Chapter 1: Rias Has A Duty

Chapter Text

"Mhmmm, Issei... You're so amazing… Please grab our tits to make yourself feel good !" Rias said in a sexy voice.

"Yes, Issei… ! Play with our boobs as much as you'd like. They're all yours!" Akeno said in a teasing voice.

"Why don't I ride you while you relax and play with our boobs, Issei…?" Rias mounted him and started bouncing her hips and down. "Ooooh ! So good… !"

"While she rides you, issei, why don't I lick your balls? Or would you prefer to use my boobs as a pillow? I'll let you do anything !"

"So virile !"

"So good !"

"Heh heh… Heh heh heh…" Issei enjoyed a heavenly moment of intimacy with his two girlfriends.

Yes, everything was perf-

Issei woke up from his dream.

"You already hogged him all to yourself last time! He wants to play with my boobs this time…!" Rias aggressively barked at Akeno.

"Oh, my! But if he prefers mine and wants to play with them again, is that so bad ?" Akeno passively-aggressively retorted.

"Ghh…! Issei! You want to play with mine this time, right?"

"If you want to play with mine, Issei, they're right here for you, okay?" Akeno grabbed his left hand and rested it on her cleavage, taking the lead.

"Wh-wha?! I-I-" Issei had no clue what to say.

"You…! Fine! Then I'm taking his penis this time!" Before Akeno could act, Rias mounted him and inserted his penis inside her vagina. "Ngh ! Play with her boobs as much as you want, Issei. I'm the one who will receive your seed tonight."

"Oh my… Well, ride it as much as you want. I'll keep his face of pleasure all to myself, okay?" Akeno shoved her lips onto Issei, blocking Rias from view with her face.

"H-hey! I want to see the face he makes when he cums!" Rias struggled with Akeno.

"Mhhhhhmm …" Akeno refused to move out of the way.

And, throughout their scuffle…

"Ghhmmm…!" …Issei let out a compromising groan.

"Heh? You came…? Oh…" Rias was disappointed.

"Already? Oh, my! Too bad your turn didn't last that long, Rias." Akeno gloated – though also with disappointment hidden behind her words. She backed off from Issei, freeing his mouth.

"I-I'm sorry, President…!"

"It's fine, Issei." Rias leaned forward and gave him a pecker on the lips, ultimately unmounting him to cuddle him from one side while Akeno cuddled from the other. "I'll take it as a compliment. After all, you lasted a little longer with Akeno yesterday, so that must mean my body feels better."

"Oh, my! I thought it meant you were less skilled at managing a penis' release. I'm learning so much from you, Rias." Akeno chipped in.

"Grrr…!"

"Heh Heh heh heh…" Issei had no large contributions to make to their argument.

…He was too distracted by the large, soft, pillowy boobs hugging his shoulders.

For a couple of months now, Issei had been living a heavenly hell after entering an official relationship with Rias and Akeno at the same time. Neither wanted to give him up, so they formed a throuple with plenty of possessive discord within it.

The present mini-fight was an almost nightly occurrence due to how much each woman loved Issei and wanted him.

'I'd be lying if I said I don't like it… Heh heh heh…' He basked in the glory of being squished by the two largest, softest sets of boobs he had ever seen.

Still, Issei felt guilt.

The core issue of the frequent mini-arguments between Akeno and Rias was his insufficient virility to satisfy both of them.

Without exception, he never lasted long in bed, meaning it was impossible for him to properly please both women on the same night; Not just that, but most nights, he did not even please one of them. As a result, they had to fight for his energy since he lacked enough for both.

The two women did not seem to blame him, but he most certainly did.

Nevertheless… '…How much can it be my fault? ANY man would lose it and release too fast! H-hah… Just feel these boobs… Hah…' His thought processes and emotions never drifted too far due to the sedating effect of being hugged by the breasts he loved so much. 'It's impossible… Their bodies are too erotic… If I can't get hard again right away with these two around me, then no one can! Just look at them…!'

Akeno Himejima was a short woman standing at 5'6 with violet-colored eyes and a lean figure… If not for her enormous breasts and ass adding unbelievable curves to her physique. Her hair was black, voluminous, and very long, reaching all the way down her ankles – usually in the form of a ponytail tied with a ribbon. When she was in bed with Issei, though, she let her hair run loose. 'I love sinking my hand in her boobs! They can swallow all my fingers, my palm, and there's still more to grab! And she's so dirty too…! Was she always this erotic? Or is it just to please me? I don't know, but I love it!'

Rias Gremory was taller, standing at 5'8 with beautiful light blue eyes and a slender frame… If not for her huge breasts and ass as well. Rias had long legs and wide hips, giving her an even more prominent hourglass figure due to her narrow waistline. Her crimson-red hair was long and straight, reaching down to the back of her thighs, almost always run loose. 'President has the best body I have ever seen! Her proportions are insane! Her boobs are a little smaller than Akeno's, but they're firmer! But then who has the best ass?! I don't know…! Life is so difficult… The struggle of man…! Which pair of boobs do I want to squeeze? Which butt?'

"Rias." Akeno suddenly said. "Shouldn't you go shower? Issei released his big . Manly . Load . Inside you, after all. You'll stain the sheets once it leaks out."

"And I assume that while I shower, you'll take him to the corner of the bed and spoon him all to yourself?"

"Oh, my! You think I'd do that…?"

"Grr…!"

And thus the night proceeded onward…

Issei relaxed with the members of the Occult Research Club in their club room.

"It's been pretty peaceful recently, hasn't it, Issei?" Asia said, sitting beside him.

"Let's hope it stays that way!"

"You like it when it's peaceful too?"

"Yes, because I love it when…" His eyes scanned around for every female chest in the room. "…Everyone's perky. Heh heh heh…"

"I want to be perky for you too, Issei!" Asia gave him a bright smile, innocent to the perversion going on in Issei's mind.

Asia was a foreign girl from Italy who had a rough past involving fallen angels and the church before being rescued by Issei and turned into a devil by Rias. She had waist-long blonde hair with bangs covering her forehead, green eyes, and was overall very slim and short, with breasts barely breaking into the B-cups and her ass being best described as 'perky'. In terms of character, Asia was the living embodiment of the words 'cute' and 'innocent'.

"By the way…" Asia whispered to him.

"Hm?"

"I was wondering if… I could sleep in the same bed as you, Rias, and Akeno tonight…"

"S-same bed…?"

"It feels lonely now that you three started dating… Why is every bed in that mansion so big?! I want to be with you three so I don't feel so lonely!" Asia made a grand announcement.

"Hoh. Could I join?" Xenovia popped from behind Issei with an innocent – or naive – smile. "You guys do a lot of babymaking, don't you? I wanna join. We can practice with those condoms I bought."

Xenovia was one of the tallest women in Rias' peerage, standing at 5'5 with short blue hair that went down to her neck from the sides and back, and front bangs that stopped right above her amber eyes, with a green streak on one of the rightmost bangs. Bodywise, she was arguably the fittest of the entire peerage due to the harsh training she went through as a former angel, with faint muscular definition present throughout her body. Despite being lean and fit, she had large breasts for her figure, along with a voluptuous rear that was a mix of blessed genetics and muscle mass.

"D-don't go around saying that stuff, Xenovia!" Issei was always thrown off by Xenovia's lack of common sense – a consequence of her upbringing under angel tutelage.

"Oh? But don't you guys have sex, like, all night, every night? I bet I could help."

"S-sex all night with Issei…? I'll have to join that too if I sleep on the same bed…?" Asia instantly got flustered, turning red.

"Th-that's…! Uh… Have realistic standards…!"

"Well, I don't care. Can I join too or not?"

"Issei…" Koneko joined them. "…Are you perving again…?" As always, there was no emotion on her face and quiet voice.

Koneko was a VERY short girl, standing at 4'6, making her shorter AND slimmer than Asia. Despite that, her strength was no joke because she was Rias' Rook piece, making her able to easily send Issei flying through any wall with a single punch. She had amber eyes and short hair just like Xenovia, but white with sidelocks that ran slightly past her neck. Her voice rarely broke off from its low tone, and her face hardly ever expressed emotion.

Still… "…I don't want to be left out. Can I also sleep on the bed? I don't want any sex, but we can cuddle." …She had an affectionate side to her.

"Looks like you're in trouble, Issei! Hahahah!" Kiba laughed from the other side of the room. He was Rias' Knight piece and avoided involving himself with the girls.

"Issei…? Are you seeking out new girls to have fun with? How many holes can a horny guy like you need…?" Akeno appeared in front of him with a kind smile – which could mean anything from genuine kindness to unbridled wrath.

"Issei? Aren't we two enough for you? How many pairs of boobs do you need to be satisfied? I thought we loved each other." Rias appeared beside Akeno with crossed arms and a light scowl – unlike Akeno, she did not hide her emotions behind fake smiles.

Issei's peace was soon about to end. His life was about to enter a new chapter where he had to wrestle with the five women of Rias' peerage who deeply desired him-

"Rias!" The club door slammed open.

Everyone looked toward it.

It was Sona, the heiress of the Sitri Clan and leader of the other devil peerage in that school – essentially, the Rias of the Sitri family. In that school, she acted as President of the Student Council, whereas Rias was President of the Occult Research Club – a façade for her and her servants to have a personal club in the school.

Beside Sona was Saji, a student and pawn of Sona's peerage. And beside him, was…

'Who's that…?' Issei's eyes widened in surprise.

"Ghh…!" Saji was using his arm and shoulder to help a MASSIVE black man walk.

The mere look on Saji's face was a clear indicator of how heavy the black man was, magnitudes larger than him in terms of height and muscle mass, with a physique so thick that his white shirt bordered on ripping apart with each breath; The same applied to the blue jeans on his legs, which were already ripped in many places. He had black eyes and a bald head.

Whoever the black man was, he seemed to be in poor health, though there were no noticeable wounds on his body – at least as far as Issei could tell with him dressed up.

Initially, Issei assumed no one in that room understood what was going on.

Then, he noticed Rias had a look of utter shock, with her eyes misty on the verge of tears.

Akeno also seemed to have some awareness, with her mouth slightly open in surprise.

"President? You know who that-"

"Marcus!" Rias rushed toward the black man – whose name seemed to be 'Marcus' – and took him in her arms, sitting on the floor with her feet under her butt to rest his head against her lap. "Are you okay?! Marcus?!"

"Rias… Ughhh…" The man muttered before his head collapsed to the side, passing out.

'He called her Rias? He knows her…?'

"Marcus! Wake up! Marcus…!"

"Asia." Akeno said, implying a command to Asia – as Rias' Queen piece, she was essentially second-in-command.

"Huh? Ah! Yes…!" Asia shot to her feet and rushed over to use Twilight Healing on Marcus-

Rias raised a hand. "Stop. That won't help him."

"I-it won't?"

"No… His problem is something else…" Rias was holding on to avoid crying.

"I-I see…" With a sad look, Asia returned to the sofa.

"My apologies, Asia. I thought your ability might be able to help, but I was mistaken… It's a curse with so many unknown traits to it…" Akeno got up and approached Rias to observe as well.

'Curse…? Unknown traits…? What…?' Issei was thoroughly lost in the plot.

"I can't believe he's back…" Koneko said before walking over to Rias, looking down at Marcus from over her shoulder.

"…Yeah." Kiba followed Koneko.

Apparently, everyone but Issei and Asia knew who Marcus was.

"Hey, Issei." Xenovia whispered.

"Wh-what?"

"Who's that?"

"Oh. I guess you don't know either, huh? I have no clue."

"Huh… Well, whoever he is, he seems important somehow."

"I-I think so too…"

"But that aside… Incredible, isn't it?"

"What is?"

"His muscles." Xenovia looked straight at the man's body, ignoring his face of pain.

"Muscles…?"

"He's got a very strong body. Look at the boulders on his shoulders… The chest and back too… I've been trying to understand more about society since I quit being an angel, and I think he's got the type of body that women would describe as attractive and masculine."

"Uh…"

"What do you think? As a man, you should be able to tell, right? Is he attractive and masculine? Would most women be interested in him? The dark skin is interesting too, isn't it?"

"S-stop saying weird things!"

"Hey, Asia." Xenovia called out to her. "Do you think that guy is attractive and handsome?"

"Heh?!"

"You know, because of the muscles and height. Girls like taller, bigger men, right? That guy's shirt barely fits because he's so strong. Also, what about the dark skin?"

"I-I don't know what you're talking about!" Her face turned red again. "Issei…! I'm sorry!"

"There's nothing to apologize for. You can just ignore Xenovia…"

"No one gives me a straight answer…" Xenovia gave up.

With Asia and Xenovia calming down, Issei focused his gaze on everyone grouped up around Marcus. 'I feel a little jealous that President is caring for him with his head on her lap… Aaaah! Don't be like that, Issei! He's clearly hurt!'

"Rias. What are you going to do?" Sona asked with a serious voice – her usual.

"Sona… Do I have to make that decision now?"

"Yes. When I saw him approach the school, I didn't recognize him because his body has changed so much, but his identity became evident once I looked at his lower body."

'His lower body…? What about it…?' Issei looked at the man's pants to understand. 'What the-!!'

There was a COLOSSAL bulge running all the way from his crotch to slightly past his knee. The man sported a MASSIVE erection – not just long, but VERY thick too; Easily girthier than Issei's upper arms. It was pulsating so aggressively that it threatened to tear his pants further. 'Is that why his jeans are so ripped?! Because his dick keeps shaking like crazy?!'

"B-b-b-big…!" Asia buried her face on Issei's shoulder, scared.

"Woah! Dicks can be that big?" Xenovia sounded more impressed than anything.

"It's a big black cock…" Koneko muttered.

"A nasty curse…" Kiba avoided looking.

"It's a true big black cock." Akeno spoke with a serious voice for once.

"…I know. It's bigger and thicker than ever. His balls too…" Rias said vulgar words with a sad tone; A bizarre situation.

'Can everyone stop talking about his penis?!' Issei felt out of place.

"Rias." Sona demanded her attention once more. "You know as well as I do that he's a threat to the stability of your peerage and probably mine. We should kill him."

"I'll take him back as my servant."

Everyone was surprised by Rias' decision, especially Sona.

"Really? I never expected to see you forgive a stray devil, Rias."

"Everything that happened to him is my fault. I'll… Take responsibility." Rias slowly moved a hand to the man's lower body.

…And then started slowly and mechanically stroking the immense protrusion through his pants; It spasmed even more upon contact.

Sona seemed impressed. "Rias… You're really going to do it-"

"President! What are you doing?!" Issei shouted, freaked out from seeing her touch another man's penis.

"Issei-"

"You can't do that!"

"Issei!" Rias raised her voice just slightly enough to fully shut Issei down. "…All I'm doing is taking responsibility for-"

"Ghnn…!" Marcus suddenly squirmed in pain.

"Marcus…!"

"He's on the verge of death already." Sona explained. "It would be smart to put him out of his misery-"

"I won't do that! Marcus…!" Rias moved her hand into his pants without hesitation and started stroking at a fast pace; Her hand motions could be easily seen through the fabric of the tight-fitting jeans, embracing the girth of the man's large penis in long, fast motions.

"Hey, hang on a moment…!" Issei was in shock over how casually his girlfriend – the tough, commanding Rias – was directly touching another man's genitalia; Pumping him furiously, no less.

"This is not good…! He's too pent-up…!" Rias pulled her hand out and stared at it. It was DRENCHED with a slimy, dense substance: precum. Strings connected one finger to another no matter how much she separated them.

"He needs release now!"

"Release? What… What are you talking about…?" Issei did not like what he heard.

Rias ignored him. "Sona! I need an empty room to-"

"I can free the infirmary for you, but are you sure? If you take him back as a servant, you'll have to constantly-"

"I don't care. It's done! It's my responsibility!" Rias gently rested Marcus' head on the floor and stood on her feet, looking at Sona with intent while bringing a hand to her own chest. "I, Rias Gremory, heir apparent to the Gremory Clan, will accept the Black King piece back as my servant!" Without realizing it, she smeared her uniform with the viscous substance.

Sona, Kiba, Koneko, and Akeno were all in awe of Rias' determination. Xenovia, Asia, and Issei were confused – especially the latter, feeling like he had just witnessed his girlfriend cheat on him by stroking a gigantic black penis as if it were something completely normal; And, through all of it, Rias seemed remorseful and worried.

"We'll carry him." Kiba and Koneko took Marcus out of the room.

"I hope you don't regret this, Rias." Sona left with Saji.

"I'll explain the situation tomorrow." Rias addressed everyone else and left-

"President! Wait!"

"What is it, Issei?! There is no time!"

"But…! I don't understand what happened just now…!"

"Look- Ah- S-sorry…!" Rias touched Issei on the chest, not realizing what hand she used. His uniform was now also smeared with the thick, sticky substance coating her fingers. "Oh, I got some on myself too…! Tch…! There's no point cleaning this up. There's going to be more in just a few minutes."

"What is that supposed to mean?!" Issei was disgusted by the viscous liquid on both of their uniforms. "President, I don't understand anything…!"

"I… I don't know how to explain. I'm doing what I have to as a master. I… I guess I'm sorry. Akeno, take care of Issei."

"Of course, Rias."

She left.

"I don't… Get it…" Issei sulked in place.

"Oh, my! I guess this means I don't have to compete for your penis tonight, Issei!" Akeno hugged him from behind to provide comfort with her soft chest squeezing against his back.

"What do you mean…? She's going to be back way before night, right...?"

"I very much doubt it. Marcus needs a lot of… Attention."

"Attention…?"

"…Forget it for the moment, Issei. Why don't we go home early and cuddle in bed? All naked …" Akeno erotically provoked him to change the subject.

It would have worked if not for…

"Woah! This is super creamy! Is this what they call precum?" …Xenovia inserting herself into the conversation and scooping some of the substance off of Issei's uniform with an index finger. "It smells good… I didn't know that penises could produce something this thick. Is real semen even better?"

"Xenovia…!"

"Oh, right, you're not going to give me an honest answer, are you? I get it." It looked like she was going to drop the subject, until… "Hey, Asia! Do you think it smells good?"

"Heeeh?! Uhm…! I-it kind of does…?"

"Hey, finally a direct answer! But does it TASTE good?" She inserted the finger into her own mouth without hesitation, gulping down the creamy liquid. "Hm…! Hey, this is kind of good!"

"I-it is?!"

"Yeah, let me get you some so you can try it out, Asia-

"STOOOOOOP!" Issei murdered the conversation by frantically rubbing his hand against the smeared area of his uniform.

Xenovia looked disappointed.

Asia was relieved.

Akeno laughed.

And Issei…

"Uugh…" …Now had another man's precum all over his palm.

"A-Asia…" Issei glanced at Akeno.

"Asia…" Akeno glanced at Issei.

"What?" Asia looked at them both. "Am I… Bothering?"

"Uhm…"

They were in the massive royal bedroom that was built for Issei by Rias' father a while ago.

Akeno was wearing trim-lace red lingerie that left her nipples and crotch in play view – though hidden under the sheets – and Issei shirtless and in his boxers.

…But Asia was too innocent to understand that she was ruining what would have been a – quick – moment of sex.

…

'No, it wouldn't…' Issei could feel that he was unable to get hard, too worried about Rias. 'With or without Asia, no sex is happening tonight…'

"You're not going to let go, are you, Issei?" Akeno could sense the worry in him. "Rias will explain it tomorrow…"

"I'm worried about her! She's not in bed with us for the first time since forever! Where is she right now?!"

"I'm worried about Rias too!" Asia supported Issei.

"What even is a Black King chess piece?!"

"Does that mean he has the same authority as President Rias?!"

"Oh, my… So many questions. I suppose it'll make things easier for Rias if I explain the situation to you two. Pay attention, will you…?"

Roughly one year ago, there was a foreign student from America who often contracted with the devil of Rias' peerage.

The one to attend to him was usually Akeno herself. One day, Akeno could not go, so Rias did in her stead since Koneko and Kiba were already too busy as well.

That foreign student was, of course, Marcus himself. Back then, he had just turned 18 and looked much different than now, with an afro and a much, much skinnier physique and shorter stature.

Marcus had trouble in Japan. Due to not understanding the language properly yet and being of dark skin, he found himself the victim of bullying and general xenophobia. According to him, even living in his building was a small problem, with the neighbors threatening to call the police at the smallest of non-events.

To avoid feeling so lonely, Marcus summoned them often, enjoying Akeno's company and willingness to help him with Japanese.

After that one day when Rias went in her place, he never summoned Akeno again, having hit it off too well with Rias. Both him and her were big fans of Japanese culture, especially anime, meaning they had a lot to talk about while she helped him with the language. Over time, they became close friends with each other.

On a sad day, Marcus summoned Rias in a different set of circumstances.

Deadly circumstances: He was lying in a pool of his own blood in an alleyway.

Whether it was due to xenophobia or poor communication due to not understanding the language well, he found himself in an altercation with three thugs who ultimately stabbed him before robbing him.

He summoned Rias because he had fallen in love with her and wanted to say goodbye before passing away.

Rias had found so much in common with Marcus that she wanted to save his life – much like she saved the lives of every one of her servants – but there was a problem: Saving Marcus would not take a normal chess piece; She could not save him even with 8 pawn pieces, like Issei required.

To save him, she would have to sacrifice a Black King chess piece – a unique piece that only the Gremory family had. It could only be used on males with remarkable potential for virility.

"P-potential for virility?!" Asia blushed.

"Yes. Which means, most likely, that it could only ever be used on western black males."

"Why is that?!" Issei did not follow.

"Well… Even among devils, all women know there are certain traits innate to black men."

"I-is that true, Asia?!"

"Heh?! I-I don't know! B-but he was big…" Despite Asia's cuteness, she understood exactly what Akeno meant on female instinct alone.

"So this Marcus guy had that virility potential?!"

"I think most black men do, but Marcus had it even more than most. I knew that from the moment I first met him."

"How?"

"Oh, my… Issei, women ALWAYS know. Don't you think we stare…?" She giggled, getting a rise out of provoking him.

"S-stare…?"

"At the crotches of every man we meet to know if they have hung penises." She whispered in the most seductive possible.

"What?! Asia, is that true?! Do you do that too?!"

"I don't know, I don't know!" Asia covered her face with both hands and shook like a nervous child.

She did do that too, and Akeno knew simply from following her eyes around Issei.

"Did you do that to me when we first met, Akeno?!"

"Of course I did. I stared lots and lots, curious about your penis."

"A-and… Uhm… What's my virility potential…"

With a naughty smile, Akeno brought her lips to Issei's ear and whispered… "Average, just how I like it."

"Hah… Hahahhah… Great…" Issei turned into a drooling buffoon due to her sweet breath and the proximity of her voluptuous cleavage to his face – he was easy to please, which Akeno loved about him.

"Anyway…"

The origin of the Black King piece was unknown, but it was passed down from Rias' mother to her. According to what Rias told Akeno, her mother had tremendous difficulty letting go of it.

The reason for that was because her mother knew that the piece imposed a hefty curse upon whatever person became a devil through it. Perhaps more importantly, that curse would almost indubitably have to be managed by the devil's master; In this case, Rias herself.

From the way Rias' mother talked about it, it sounded like she had some experience with that piece and its curse in the past. Akeno vaguely remembered mentions of a dark-skinned male servant in the Gremory family, but never met him, if he existed at all…

Thus, Rias relucted but ultimately decided to save Marcus by using it.

And so, Marcus was cursed with the Black King piece, but got to live.

The impacts of the curse were immediate.

"Impacts? What does the curse do?" Issei asked.

"I was with Rias when it happened. The moment he came back to life, he gained several inches."

"Inches? Of height?"

"…In a variety of places ."

"Do you have to say it like that?!"

"Oh, my! But you make it so easy to tease, Issei! Even when you have a big pair of boobs to grab and a cute blonde girl holding your arm, you're still so insecure. That's not manly at all."

"S-stop…!"

"Well, that's fine. I'm not into manly guys. I like skinny perverts like you…" Akeno gave him a kiss on the cheek.

"I-I also love playing with perverts like you, Issei!" Asia gave him a random kiss on the other cheek to not feel left out.

"Heh heh heh…" He did not mind the insults.

Akeno continued…

The Black King piece accentuated the physical and sexual traits innate to the servant it saved.

Since black males were already prone to being taller, stronger, and more virile, that meant that Marcus' body would go through significant growth in a masculine sense… For years to come.

When Akeno first met Marcus, he was 5'10 tall and weighed 160 pounds. When he appeared by the club room, he must have been 6'5 and 260 pounds – a massive growth that would likely not stop there, and it occurred within the span of a year.

The same applied to his penis size, which had an absurd growth easily noticeable by the expansion of his bulge. Before, Marcus had a large penis capable of easily pleasing women. Now, he had an enormous meat club fit to destroy any female body and ruin it for life.

"I mean… If it's just him becoming bigger in every sense… Is it THAT bad?" Issei questioned.

"Oh, my! Issei, could it be that you're jealous? Do you also want to become bigger…" She grabbed his small erection over his pants. "…In every sense?"

"Ghh…! Th-that's…!"

"You're great as you are, Issei!" Asia offered him support. "Muscles don't make a man!"

"Neither does penis size ." She stroked him very subtly without Asia noticing. "It's all about personality. I don't care about your physical traits at all… But you're free to care about my boobs."

"Heh heh heh… Okay, then…"

The curse did not just mean a significant, prolonged increase of masculinity in the physical sense. It also meant so in the sexual sense.

Specifically, the emergence of an uncontrollable sexual craving to have breeding sex.

"Breeding sex?!"

"L-like animals?!"

"Yes… Like animals. Animals don't use condoms, do they? Even though they cannot think, all animals know to procreate due to innate biological urges. Even humans have such a need, but because of how we organize society and have the ability to think, we deal with it in a variety of ways… Right, Issei…?" Akeno slid her hand into Issei's boxers and started directly stimulating him under the sheets, away from Asia's view.

"Ngh…!"

"Issei? Are you okay?" Asia was oblivious.

"Ask him in a few minutes." Akeno giggled. "Continuing…"

The curse meant the emergence of an uncontrollable craving to have breeding sex, and this craving would only grow stronger with time. When unsatisfied, the Black King servant undergoes intense physical pain and grows frenzied and desperate to satiate the curse.

That was why Rias was reluctant to save him: It would become her responsibility to keep him 'satiated'.

That was exactly the problem that led to Marcus fleeing and becoming a stray devil.

Rias did not desire to have a romantic relationship with Marcus, nor a sexual one. Moreover, she was only 17, much like Akeno and Koneko back then. She refused to engage in sexual acts under those circumstances, and she refused to allow Akeno and Koneko to act in her place. Moreover, she also prohibited him from having sex with normal women, fearful of what he might do to them with his 'enhanced' body and lust.

So, Rias tried to keep Marcus in check purely with emotional support.

…It failed spectacularly. With each passing day, Marcus became more and more impatient. He never adapted well to being a devil. Again and again, he complained and blamed Rias for cursing him with such horrible pain and insatiable cravings. Seeing his body change in real time was an agonizing experience for him, despising how he was growing bigger, turning bald, and becoming a sex-thirsty monster.

"He particularly hated his big black cock…"

"Th-that's such vulgar language…! Why do you keep calling it that?!" Asia yelled, hiding behind Issei's shoulder.

"It's the term we use for the large penis of Black King pieces. How else would any woman describe that long, thick thing that reaches past his knee…?"

"P-past his knee…?" Asia used her hands in the air to measure the distance. "Wh-wh-whaaa…?!" She somehow grew even redder.

"But, like I said, size isn't everything… Right, Issei…?" Her hand continued to jerk him under the sheets, now at an aggressive pace.

"Ghhhh…!"

Even back then, Rias felt strong guilt for putting Marcus in that situation, at times wishing she had just let him die.

Around two months later – which was a few weeks before Rias saved Issei and turned him into a devil – a drastic incident occurred that shook Rias to her very core.

Marcus was sent to form a contract with two women who summoned a devil.

Even after many, many hours had passed, he had not returned, so Rias and Akeno went to check on him.

That was when they found him and the two women…

…Covered in a puddle of semen, vaginal fluids, and sweat. The girls were almost unconscious from how hard he had fucked them. Their vaginas and anuses gaped wide with sperm gushing nonstop. Their stomachs had expanded to the size of full-blown pregnancy bumps. Their muscles were tense due to continuous spasms contracting them amidst endless mindbreaking orgasms, with their eyes crossed together and their mouths stuck open so that their tongues could dangle out, mumbling nonsense due to cum-drunk brains.

Any sane person would have looked at the two girls and assumed they had been fucked by a dozen men with insurmountable brutality.

Instead, it was just Marcus…

…And he was still hard and going at one of them even after seeing that Rias and Akeno had caught him in the act.

That was how much the curse made him crave breeding sex. His enormous penis bulged out the cum-packed stomachs of the girl, gouging them out as they struggled to moan and breathe due to excruciating contractions all over her body. Even if it was clearly a situation of aggressive rape – as easily determined by their empty eyes caused by unpaused sex, the strangle marks on their necks because of choking, and the red bruises around their inner legs, asses, and vagina due to ruthless pounding – the women clearly felt pleasure beyond normal human limits.

After that incident, Rias hoped that Marcus had gotten it 'out of his system'.

And then the next day, Marcus fled, officially becoming a stray devil, abandoning the peerage.

"What happened to the girls? Were they okay…?" Asia asked.

"They… Changed a little."

"Because they got pregnant?"

"Hm… Let's say that's it. They found boyfriends to raise the kids with them." Akeno decided to omit a part of the story.

…A part about how the girls' bodies became meatier, and their minds cruder…

"Japanese boyfriends?"

"Yeah."

"Wouldn't they… Uh… Know?" Issei asked.

"Oh, they would. But they found just the 'right' types of boyfriends. You know, the type that doesn't mind raising someone else's kid because they love their girlfriends so much." Akeno simplified a crueler part of the story.

…A part about how they settled with weak men who were easy to dominate and humiliate into submission while they continued to desperately try summoning Marcus again…

"After that…"

Rias was a strong master, so she was able to power through the feelings of guilt and failure, more than willing to kill Marcus if he were ever found again.

…But then he appeared in the club yesterday, bordering on death.

The fact that he was so injured could only mean one thing: He had been denying his cravings for long enough that his body was beginning to collapse. The size and hardness of his bursting member in his pants was proof of that. In his moment of despair, he decided to seek Rias' help once more…

…And that won over her heart, tugging at the strings of her heart with remorse.

Rias had likely always secretly wanted a chance at redemption and did not intend to let the present opportunity go.

"…Especially now that she is 18, like the rest of us. Even you, Asia, cute as you are." Akeno pinched Asia's cheek like a playful mother, still jerking Issei under the sheets, feeding a little on her sadistic tendencies. 'I'm playing with your beloved right in front of you and you can't even tell, Asia. Sorry … His penis is all mine.'

"B-but… I don't… Uh… Understand one thing. Ghhh…"

"What's that?"

"President- Nghhh…! President said she would be taking- Ughh… Responsibility for him…!"

"That she did. And then she took him to the infirmary, which Sona cleared up to give them privacy."

"T-to do what? Nghhh…!" Issei's body began to tremble due to reaching orgasm; Akeno sped up her strokes…

"…Her duty ." …And enjoyed the feeling of his semen coating her hand.

"I-Issei?! Are you okay?! What's going on?!" Asia panicked from seeing Issei grit his teeth and shake so much. Soon, her eyes traveled to the sheets, where she could see Akeno's hand blatantly moving up and down. "Wh-what are you doing, Ms. Himejima?"

"Well, I'm Issei's girlfriend, so…" She finished pumping Issei's ejaculation out, pulled her hand out, and licked her fingers to drink it all up. "…MY duty ."

"I'm telling you guys, I need to go…!" Issei had an important meeting with Rias and everyone else in the Occult Research club room and was already late.

"Issei, you don't wanna miss this! I'm telling you!" Matsuda, his nerdy, pervy friend shouted.

"You're not gonna believe the shit we saw yesterday!" Motohama, his other friend, grabbed him by the shoulders.

"Grrrr…! There's nothing you can say-"

"I swear it's erotic!"

"VERY erotic!"

"Tell me, tell me!" Issei changed his mind right away.

"Yesterday, we were about to leave the school, but this guy here got a headache, so we figured we could check in with the school nurse."

"Yeah, so we went to the infirmary-"

"You entered the infirmary?!" That was where Rias took Marcus yesterday.

"Let me finish! We WENT to the infirmary BUT we could not enter because the student council prez was at the door and said we couldn't go in! She didn't even explain why! But then…!"

"Then, while Motohama talked with Sona, I peeked in through the door. I saw a girl giving some guy a handjob!"

"Huh…? Wait, really...? Wh-who was the girl?"

"I don't know because there were curtains around the bed, but I could see their silhouette. Issei, it was INSANE!"

"I-insane?"

"The girl wasn't giving him a normal handjob. She was pumping THE LIFE out of his dick! I actually didn't feel jealous of the guy, I felt sorry! She must have been CRUSHING his dick with how hard and fast she was going!"

"H-huh…"

"And he was shaking SO MUCH too! It must have hurt like hell or something, because he wouldn't stop grunting! I don't think he's from this school either, because there's no one here who's THAT big."

"B-big…?"

"Yeah! I could see through the curtains. The guy's huge! I don't mean just his dick, I mean everything! I don't know who that girl was, but she's gotta be a complete size queen nympho to like dicks that big, dude! And the cumshot… Holy fuck, he showered her! And she wouldn't stop pumping! That girl LOVES cum!"

"D-don't say that about her! Take it back!"

"Wha-?! What do you care? We don't even know who it was."

"Wait, unless you know something we don't, Issei."

"Holy crap, do you know who that slut pumping the super mega dick was?!"

"Grrr…! You're idiots! And liars!" Issei ran away, filled with anger.

If he understood things correctly, it was obvious who was the woman masturbating the man in the infirmary.

However, that was impossible! Rias would never be unfaithful! 'President loves me…! She would never cheat or do something unfaithful, even if it was to deal with that guy's curse or whatever! I know it's all a misunderstanding! I don't know how, but… But it is!'

…Even though he openly saw her grabbing and stroking the man's penis inside his pants yesterday….

…Even though the very uniform he was wearing right now was still a little stained with dry precum because he forgot to clean it up before coming to school…

…Even though Akeno said Rias wanted to take responsibility and do 'her duty'…

Even then, there was no way Rias did something sexual with Marcus.

It would all make sense soon enough.

"Good. Issei is here. We can start." Rias was sitting behind her desk with her hands clasped together on it. Based on her voice and look, the conversation would be serious, but Issei did not initially focus on that.

Instead, he focused on her eyes – there were bags under them.

Had Rias cried during the night…? Or had she not been able to sleep because of something…?

Why did she not join him and Akeno in bed?

Why did it look like she was avoiding eye contact with him?

More importantly: Why was she repeatedly making eye contact with Marcus, who was there for some reason?

They had given him a chair of his own, though it looked tiny beneath his gargantuan stature. 'He would never fit on the sofa with the rest of us… He's seriously big, isn't he…? I can see his abs through his shirt, and… Ghh…! Get less tight pants, you fuck…! Trying to show off…!' The ever-present bulge on his lower body stressed Issei out. 'Th-that's not what President is looking at, is it?!'

It was, as he confirmed a second later by following her gaze. Rias' eyes moved irregularly from Marcus' face to the enormous penis being choked within his pants. Whenever she was not looking at him, she looked at Akeno who stood beside her for support.

"She looks serious… Do you think it's something bad, Issei…?" Xenovia whispered on his left.

"I don't know…"

"At least Marcus looks healthy today. Rias must have done something. Isn't she amazing?" Asia whispered on his right.

"Grr…"

"Everyone…" Rias finally spoke up; Everyone's attention immediately went to her. "…I want to introduce everyone to Marcus Moore, your newest peer. His piece is the Black King."

"Black King? Aren't you the White King, Rias? Does that mean he is also our master?" Xenovia was confused; She was not present during Akeno's explanation last night.

"No, the Black King is a special piece that…" Rias paused. "…It's easier if I show it. Marcus, can you please come over here? There are new members since you…" She paused again. "Issei, Asia, and Xenovia weren't here last year. They don't know you yet. Please come and introduce yourself."

Issei, Asia, and Xenovia looked at Marcus with open mouths, curious to finally hear his voice in a normal setting and discover what his personality was like. Based on his appearance, they all expected him to be the living stereotype of a dominant and cocky male.

"Y-y-yes…! Right away, Rias- Ms. Gremory! O-or is it President?!"

"Call me Master, like you used to."

"Yes, Master!" He got up and walked over to Rias' side with trembling legs, sweating coldly due to sheer timidity. "I'm M-Marcus Moore. I already know Koneko, Kiba, and Ms. Himejima, but I'm happy to see you all again. I-Issei, Asia, and Xenovia, p-pleasure to meet you…" He bowed as a show of respect… Or tried to. In truth, he simply hunched forward slightly.

"A-ah…!" Asia got up in a hurry and bowed – or, rather, went out of her way to bow poorly too. As someone who was also a foreigner, she understood Marcus' struggle.

"Huh? Are we doing this?" Xenovia got on her feet and bowed as well, but without realizing Asia's intention of intentionally bowing poorly. Thus, she offered the deepest, most respectful bow Issei had ever seen, highlighting her athleticism and flexibility.

"Ah…! That was amazing…!" He clapped with a big, dumb smile, praising Xenovia.

"Heh? Oh, th-thanks… I guess that was kind of amazing, wasn't it…? Hahahahah!" …Xenovia was an idiot.

The brief exchange made Issei realize something: Marcus might have been a gargantuan-sized man, easily towering above everyone in that room by a large margin, both in terms of height and raw muscle mass; But, on the inside, he was just a timid guy.

That gave Issei confidence, seeing himself as socially superior to him. 'I'm so stupid for being worried. Girls like personality and confidence, not looks! This guy's got nothing on me!'

For the past year, Issei had lived an enjoyable life with several beautiful girls around him showing constant interest in him. Even while dating Rias and Akeno, there was an implicit understanding that it would be perfectly okay for him to hook up with other girls and add to his throuple if he so wished; He was that popular within the peerage. 'Asia, Koneko, even Xenovia… Everyone here is mine! I'm not being selfish, just realistic!'

After sorting out his insecurities, Issei felt as good as ever. Nothing could threaten his happiness and growing harem! 'I'll be the Harem King!'

Rias got up and stood beside Marcus. The sheer size difference between them looked even more ridiculous. There was more than enough mass for Marcus to swallow three Rias whole.

"Marcus belonged to my peerage before becoming a stray devil one year ago. Issei, Asia, Xenovia, you don't know the story, but-"

"I already told Issei and Asia, Rias. I'll tell Xenovia later." Akeno cut in.

"Ah. Good. That makes it easy. Everyone: Marcus will be rejoining my peerage. I have chosen to forgive him for leaving and he will be in my care from now on. I want everyone to treat him well."

"E-everyone, I will be in your care!" Marcus hunched forward again. "I… I am so sorry for leaving! I apologize!" Despite the deep voice, it was easy to feel the sorrow in it.

Everyone greeted and welcomed him into their group.

"Marcus is a Black King." Rias continued. "By saving his life and turning him into my servant, I gave him a curse for the rest of his life, so it is my responsibility to take care of him. Therefore, I will be satiating his big black cock whenever needed from now on. It is my duty as his master."

"Rias- I-I mean, Master…! Thank you very much…! I… I am so sorry for causing you all this trouble! This is my fault for having this hideous body…!"

"It's okay, Marcus. It's not your fault. Your big black cock…" Rias looked directly at the large, thick protrusion running past his knee. "…Is my responsibility. I know you're a good person, so don't feel bad." She touched his chest to console him.

"No, but I…"

"You felt guilty about leaving, didn't you? And about hurting those girls that day… I could see it in your face."

"…"

"And you were nearly dead yesterday. That means you were holding back on acting out and having sex with girls, isn't that right?"

"I… Didn't want to hurt anybody else… But I did… I did rape a few girls…"

"It's okay!" Rias took his head – as difficult as it was because of his height – and hugged it with her soft chest, affectionately caressing his hair. "…It's all my fault. You won't have to worry about any of that anymore… I will take care of your body and needs from now on… You don't have to hate yourself…

'Wh-what the hell is happening…?' Issei could not believe the words uttered by Rias, nor the fact that she was giving Marcus the same affectionate breast hugs that she often gave him. 'I… I don't want to ever hear her saying those sorts of vulgar words again unless it's to me…! I need to talk to Rias in private.'

"What's a big black cock?" Unfortunately, Xenovia asked a question that forced the conversation in a direction Issei did not desire. "Everyone's been saying that since yesterday."

"That is the technical term we use for large black penises from devils cursed with the Black King piece. Black males with that piece have enhanced penises that are constantly erect and in need of release, or they suffer significant physical harm and can even die. They're satisfied only by… Intense, prolonged sexual breeding." Rias looked to the side, too innocent to speak without blushing a little."

"Intense breeding…? So… You're saying that you'll let him use your body for sexual release whenever he needs?" Xenovia spoke without tact. "You'll let him penetrate you all the time with his 'big black cock'?"

"If need be. For now, I am focusing on pleasing his needs in other ways, such as with my hands-"

"P-President!" Issei could no longer hear it quietly. "Wh-what are you talking about?!"

"Issei…" Rias averted her gaze. "…I understand how you feel, but…"

"Issei, calm down…!" Asia tried to pull him back down to the sofa.

"What do you mean 'but'?! You're my girlfriend…! You're saying you'll have sex with another man?!"

"It's my responsibility to give him the release he needs to-"

"Who do you think you are?!" Issei rushed over to Marcus and glared up at him with fury in his eyes. "Do you think you can just come in and ruin President's life like this?! She's happy with me…! You can't force this on her! It's basically rape!"

"I-I…!"

"You what?! You're a stray devil trying to take advantage of President's kindness-"

"Issei!" Akeno got in the way between them. "Stop." During a moment in which Rias lacked the strength of mind to shut him down, she took her place, crushing Issei's momentum with a commanding tone and intense glare.

"Ghh…! But…!"

"I'm sorry…! I'm so sorry…! I'm causing so much harm to everyone…! I never wanted it to be like this…!"

"D-don't try to gain pity points…!"

"I'm not trying to do anything…!" Marcus began full-blown sobbing with tears running down his eyes. "I felt so guilty every day… It's awful to see my body become so big in the mirror…! I can't sleep because I'm always hard and thinking of sex…! The girls I impregnated…! They just wouldn't stop asking for more, and I wouldn't stop using them more, rougher every time…! I came to Japan because I like anime and cosplay, not… Not to turn into a sex monster…! And now I am making Master's life a living hell just to keep me healthy! I wish I were dead!" He shouted with fervor, turning the room silent with his teary emotional outburst.

For what felt like an eternity, no one said anything, silently watching him sob and tear up further…

"Khh…!" Until he let out a random shriek.

"Marcus?!"

"N-no, Master…! I'm fine…! It's okay…! Nghhh…! Ghhhh…!" His best efforts to feign well-being were futile before the crystal-clear contortions of horrible pain across his face.

"Rias, I think he needs…"

"I know, Akeno. Issei, back away."

"What are you gonna do?!"

"…Give him attention right now. This is all my fault for not controlling the conversation better. Stress makes the curse act up. Get out of the way, Issei."

"A-absolutely not! H-hey…! Akeno…! Let me go…!"

"Oh, my! So sorry, but Rias has a duty to fulfill, Issei. Won't you be happy with the Vice-President…?" Akeno dragged Issei back to the sofa and sat beside him, forcing Xenovia out. Asia hugged his arm too. "You can grab my boobs if it'll make you feel better."

"No! President, what are you-"

"I would tell everyone to leave, but I still have something to say, so forgive me as I attend to Marcus while speaking." Rias lowered Marcus' pants.

His monstrosity of a penis sprung out, somehow managing to stand tall despite clearly weighing an absurd amount, reaching all the way to Rias' chest due to its length and their height discrepancy; It promptly smeared her uniform with precum and made her flinch from the strong impact.

To say it was massive would be an understatement. Its length and girth were such that everyone in the room turned silent upon laying eyes on it, shocked by its aggressive throbbing. The entire member was covered in an absurd coating of slimy, glistening precum, all the way from head to shaft – so much so that it dripped on the floor, some landing on Rias' feet. Possibly more impressive, it had dozens of dense veins running along its length.

And then there were the…

"…HUGE BALLS! Holy crap!" Xenovia shouted in shock. "I didn't know balls could be that big…! Where do you hide them when you have pants on?! They're bigger than tennis balls! WAY bigger! Issei! Asia! Are you seeing those balls?!"

"X-Xenovia…"

"I'm serious! Look at them…!"

"It's normal." Rias cut in. "Marcus was always well-endowed, but the Black King piece makes his genitalia even more prominent. They'll likely grow much bigger with time too. Do you see how it's pulsating? He needs release, and it has to be from a female's hand… Self-indulgence won't do anything because of the magic associated with it. I'll have to deal with it."

"President!" Issei burst out without thinking.

"…What?"

"Y-yesterday… I-In the infirmary… What did you do…?"

She side-glanced at him for a few seconds before answering; There was regret in her eyes. "…This." Rias grabbed Marcus's penis at the glans and started stroking him – hard and fast.

Too hard.

Too fast.

The intensity of her motions was such that squelching echoed in the room due to how furiously she gripped it with her small hand, not able to cover even half of his girth; Similarly, the strength of her grip barely resulted in any squeezing, showcasing how hard his erection was.

It was a brutal reality check for Issei; Whenever he received a handjob from her or Akeno, they grabbed much lighter and stroked much slower. If Rias had been grabbing his penis with even half the strength she was grabbing Marcus', he would easily cry in pain.

And yet, Marcus did not cry in pain… "Ghh… Mngh…" Instead, he grunted in pleasure, leaning back against the wall to avoid collapsing on the floor. "Keep going…!"

"Yes… Please relax and release whenever you need. Don't worry. I can keep stroking for a long time… If you need multiple shots, I won't hesitate to jerk you until that point…"

"Thank you…! I'm sorry…! Thank you…!"

"It's okay." Rias smiled at Marcus. "It's my duty to milk your big black cock-"

"P-President…" Once more, Issei interrupted; This time with a weakish voice from sadness. "You can't… Do that…"

Rias glanced at him with disappointment in her eyes – most likely disappointment at herself. "There's no way around it. Marcus' big black cock needs regular service. It's my duty…"

"Focus on my boobs, Issei… Here…" Akeno grabbed his hand and made him grab her chest.

It did not work. Issei could not take his eyes off of Rias jerking a penis obscenely bigger than his own, and with much, much more effort and intensity than she had ever used on him.

"There are other girls here… Who don't have boyfriends… Why not them…?" In a moment of despair, Issei argued to offer the girls he had not developed a full relationship with yet.

"I can do it, President." Koneko took his lead; Her gaze was focused on Marcus' penis. "I'll masturbate his big black cock. If he needs it, he can use my body too. He is really big for my small body, so I might feel too good… But I'll do my best."

"I can try it too. Sounds like a fun challenge." Xenovia, too, would not stop looking at it. "We could fight in bed. Whoever wins, stays on top."

"Rias… Do you want me to do it? He might be too much just for you." Akeno also offered herself.

"I-I… I…" Asia lacked the bravery but had the sentiment. Though her physical stature was greater than Koneko's, she likely did not have the same durability.

"I can try to find a girl for him…" Even Kiba tried to pitch in.

"No. None of you will do anything. It isn't that simple. None of you are accounting for the fact that the Black King curse will- Wh-wha-?!" Rias was cut mid-sentence by a surprising event.

"GRRRRRRRRRRRR…!" A mad grunt…

…Followed by an EXPLOSIVE, IMMENSE burst of semen barraging out of Marcus' expanded urethra, painting the front of Rias' uniform with a ridiculous volume of semen.

"GRRRRRRRRR…! GHHHHHHH…!" Marcus entered a standing seizure, clenching his teeth and contracting his muscles until his uniform burst ripped in several places, exposing his bulging, veiny muscles; Amidst his frenzied outburst, he grabbed Rias and inserted his penis between her thighs from behind.

"M-Marcus, it's okay…! Calm down and- Ghnnn!"

"It's starting to huuuuuuuurt! Nghhhhhhhhhhh!" With freakish fierceness, he began slamming his hips back and forth while his mammoth dick was tightly snugged between her bare legs, using them as a masturbation tool – Rias rarely wore stockings or pantyhose.

"Nghooh! You're going…! Too hard…!"

"I can't…! Ghhhhhhhh…! Control….! Nghhhhhhhh…!" Marcus reached around Rias and grabbed her breasts, squeezing his hands with so much force that her face immediately contorted into one of pain.

"Nghhhh… !"

"President!" Issei got up and-

"Issei. Don't move." Akeno pulled him back down, silencing him with her eyes. "Rias can handle herself."

"But he's hurting her…!"

"I'm okay, Issei…! Mnghhhh… ! It's fine…! He needs to shoot as much as he can…! To stay healthy…! Keep going, Marcus…! You can hump me as long as you need…! Let it all out…! Use my thighs to masturbate yourself as much as you need…! Nghhh … Please… Nobody interrupt… Even you Issei… Just watch…! Unghh …"

"Grrrrrrr…!" Marcus did not hear her, immersed in his own sensations.

Soon, another thick rope of cum came out of his urethra, shooting at the door on the other side of the room with scary speed.

Then, another, this time landing on Koneko's uniform by accident, on the chest. "Hot… And smelly…"

And another, hitting Xenovia straight in the face. "Shit! That hit hard…! It's like I got punched!"

One more, hitting Akeno- "Oh, my!" She used a magical shield to stop it from hitting her, Issei, and Asia. "He's VERY virile, isn't he…?"

"Sorry, sorry…! I'll cover it!" Rias put both her hands in front of Marcus' pulsating glans, keeping them a few inches away to block the next jets of cum to shoot. "Nghhh… Go ahead…! Mnghhh…! Play with my… Boobs… As much as you want…! If it helps you shoot it out, Marcus…! Oooooh… !" She devotedly remained in place on her tiptoes, taking the man's animalistic humping and tit-kneading.

"Nghhhh !"

"Cum as much as you need! Sate your urges…!"

"Mnghuuuh… !"

Several minutes passed, and the humping kept going and going. 'How long is he going to do it?! How is he shooting so much?! It's not supposed to last that long…!' It felt like no matter how much time passed, Marcus had an endless supply of semen to release, with Rias' inner legs turning red from the burning friction – despite ample precum acting as lube – and her hands becoming so covered in sperm that there was a waterfall of cum permanently running down her fingers.

Forming a LARGE, DENSE, puddle.

Through all of it, Marcus continued to clench his teeth and grow veiny as well as sweaty.

It did not take long for Rias' face to turn red… "Nghhh …. Ghnn … Mnghhh …" …And for her grunts and groans to turn into sweet moans. "Don't look…! Issei…! Don't look…! Nghh …"

Issei did not understand why she made that request all of a sudden. They had all been looking at Marcus humping her for multiple minutes already, so why did it matter?

Then, he saw her legs start to shake and her eyes cross slightly as she pursed lips in an attempt to control the sounds coming out of her body.

…Rias was orgasming. "Mnghhhhhhh… !" The violent, bestial humping had been pushing up her skirt and rubbing against her slit through her panties the entire time, pushing her to climax on continuous attrition alone.

Forced to stand on her tiptoes due to the man's penis pushing up against her crotch, the muscles on her legs popped out with thin veins, strained; Vaginal juices flowed down her legs. "Hah… ! Hah… ! Hah… !" Her breathing grew ragged.

By all measures, Issei was witnessing his girlfriend reach a level of pleasure that she had never expressed with him – all without anything more than a loveless thighjob.

It was humiliating in every sense possible.

"Relax, Issei…" Akeno whispered in his ear while subtly bringing a hand to his lap, teasing to touch the small erection in his pants.

'…I have an erection…?' Issei had not realized it until then. 'Why am I hard…?'

"Because it's an exciting sight, isn't it?" Akeno spoke as if she could read his mind. "Seeing Rias cumming like that makes me a little horny too. Let's deal with it together tonight, okay ?"

"Ghh…" Issei did not appreciate her teasing.

For a few more minutes, Marcus continued to hump Rias and abuse her breasts with reckless kneading.

By the time he finally let go of her, his uniform was ruined due to excessive sweat and ripping; The club room reeked of sex and masculine musk from all the cum he pumped out.

"Hah … Hah … Hah …" Rias had to support herself against the desk to catch her breath, also sweaty. "Marcus … Hah ... Hah … Are you… Hah … Okay…?"

"Yes… Thank you, Master… Thank you…!" He covered his face with his hands to conceal the tears of guilt coming out of his eyes. His cock remained tall, hard, and splurging cum despite the absurd load shot out.

"Good… Then… I… Hah …"

"President…" Issei mumbled weakly, emotionally crushed over what he witnessed. "I don't get it… If everyone is willing to help… Why…? Do you not love me anymore…?"

"Issei… Hah … It has nothing to do with that. I still love you… Hah … Hah … But Marcus' semen carries the same curse affecting his body. It has strong effects on the bodies of women who are not High Devils. In this peerage, only I can safely engage in sexual interaction with him. Everyone else is at risk. Even Akeno… Hah … Hah …" Rias made a grand revelation.

"It carries the curse?" Issei looked at Xenovia and Koneko since the two had been hit with Marcus' sperm.

Koneko was apparently aware of that information, having already taken her uniform and bra off several minutes ago without Issei noticing. "I am okay."

Usually, Issei would have been happy to see her perky breasts out, but, this time, he felt nothing.

Next, he looked at Xenovia.

Her face and uniform were still soaked – she lacked awareness of the semen's curse until right now.

…And she was licking it off her fingers. "Wha-? Is this bad? It smells kinda good, so I just tasted it a little-"

"It's fine." Rias quickly moved to her with a towel and cleaned her face with incredible speed, and then tore her uniform and bra off. "…Just a little bit won't be a big deal, but that can't happen again. Don't ingest it or ever let it touch your skin."

"O-okay. Sorry."

"Oh, my, is that what virility means? Asia would be done for with just a bit!" Akeno joked.

"N-no, I wouldn't…! Uhm… How would his s-s-s-semen change our bodies and minds, Rias…?" Asia asked.

"…In a way similar to how Marcus' body was changed. Enhanced sexual development and cravings in a… Variety of ways."

"Isn't it dangerous for you too, President?!" Issei shouted.

"The effects are minuscule on me, as I am a High Devil."

"R-regardless, there has to be another solution!"

"There isn't."

"So what?! You're going to throw our relationship away just like that?! Out of nowhere?!"

"…Issei, do you want to date someone who is sexually servicing another man regularly?"

"Of course not!"

"Exactly." Rias saddened up – she hoped for a different answer, even if she did not expect it.

"So don't do it!"

"Should I let Marcus die, then? Is that the compassion you show your peers?"

"It's not like that…! It's just…"

"It's exactly like that. Issei, I still love you, but there is no way around it. While I am using my body to service Marcus' big black cock… Please know that I still love you."

"I'm so sorry… This is all my fault… If only I wasn't an abomination… I'm hurting everyone…!" Hearing their argument made Marcus feel guiltier and guiltier.

"Marcus… It's fine…" Rias approached him and grabbed his cum-bathed penis once more, giving it gentle strokes. "…You still need a lot more release, don't you? Don't worry. I'll jerk you a lot more. Before we start…" She turned around. "Akeno."

"Yes, Rias?"

"…Take good care of Issei for me."

"It'll be my pleasure." She openly grabbed Issei's small bulge over his pants, claiming ownership of his penis. Akeno and Rias had always somewhat competed for his attention and limited sexual availability. It was not surprising to see the possessive Akeno excited.

"Hmph…" Rias was mildly frustrated by Akeno's behavior.

"P-President…"

"Yes, Issei?"

"Tell me… You'll come back to me eventually."

She looked at Marcus' erect, veiny penis and stroked faster. "…I can't make that promise. Issei… Let's break up."

"…"

"I need to help Marcus release some more. Everyone, please leave us. I may be more absent in the upcoming days as I get used to it… But I remain the same Master as always."

And so ended the meeting.

With Rias breaking up with Issei…

"Ghh…! Khhh…!" …And masturbating a big black man and his big black cock.

That night, Issei slept alone with Akeno, who tried to have sex with him to officialize their status as a 'couple' instead of 'throuple'.

It failed.

Issei could not get hard, too upset about Rias who was now sleeping in a different bedroom, sharing a bed with Marcus.

For the whole night, he mulled and mulled over it. No amount of consolation by Akeno made him feel better. Her constant reinforcement that Rias was only doing it out of duty and still loved Issei hardly made him feel better.

If anything, it made him feel more obsessed with bringing her back.

That was why he woke up with a fiery heart the next morning. 'How can I become the Harem King if I lose my main girl this easily? All I need is a moment of private talk with her! I'll pull her aside during breakfast and we'll fix all of this!'

There was zero chance he would let go of Rias! He loved her!

Unluckily, Rias was not present during breakfast. His parents were there, along with everyone else… Except for Rias, Marcus, and Koneko.

"I'll go to the bathroom!" With the simplest of excuses, Issei got himself out of their daily morning routine and headed for Rias' new bedroom. 'This mansion is huge… There are so many empty bedrooms. I wonder if more people will ever come to live with us…?'

As he approached Rias' new bedroom, Issei was greeted by an unexpected sight: Koneko peacefully standing in front of it.

"Good morning, Issei." She told him with the same expressionless tone and voice as ever.

"Good morning." He paused and stared at her. "Uhm…"

"Did you come to talk to Rias?"

"Yes."

"You can't."

"Huh? Why?"

"I was asked to guard it. No one can come in or knock on the door. Sorry."

"But why?! Don't dodge my question."

"Rias is with Marcus."

"D-doing what…?"

"Helping him."

"Grr…! Let me take a look…!" He tried to move past her, but Koneko blocked his way.

"You can't look, Issei. Rias needs privacy to attend to Marcus. It's not healthy for you either."

"Attend how?! What are they doing in there?!"

"You don't want to know."

"Yes, I do!"

"Are you sure?"

"Yes!"

"She's letting him dry-hump her."

"D-dry hump?!"

"In a variety of positions."

"You didn't have to tell me that part! And how do you even know if you can't look inside?!"

"…You asked." Koneko ignored the second part of his question. "I thought you wanted to know for perverted reasons-"

"Don't joke with me, Koneko! This is serious!" He tried to get past her again.

"Issei." Koneko changed her tone; There was an implied threat in her voice. "Rias is doing what Rias has to do to protect us. Like she helped you, she is now helping Marcus. Accept it."

"Ghh…! I just want to-"

"Nghhhh ! Mnghhh ! Uuuungh !" Deep, guttural moans suddenly leaked from the room, accompanied by wild bed creaking. "Keep going…! Go as hard…! And as fast…! As you need…! Marcus…! Hooooh… ! Let it all out…! Wherever you want! Focus on your pleasure…! Thrust at will…!"

Issei froze up. "What… The…"

"You shouldn't have heard that…" Koneko raised a hand against the door to cast a spell. "Rias used a soundproofing spell to keep that from happening, but it must be hard to maintain focus with Marcus humping her so hard in a mating press… I'll keep the spell up on my own from now on."

"H-heh…? Soundproof…? Mating press…? Th-those moans are happening right now but you're keeping them from coming out of the room?! The whole time we were talking, Rias was moaning like that?!"

"No."

"No?!" He felt relieved.

"…For a few hours now."

"Gnh…!" Issei was crushed.

"Sorry, Issei. Rias is only doing what she has to. Understand and forgive her."

"This is all… Ridiculous…" Issei walked away emotionally crushed. It was difficult to maintain his drive after hearing the words of voluntary submission coming out of Rias' own mouth.

With each step, all he could think was… '…She's moaning right now… I'm not hearing, but she's moaning… Why is she moaning…? Because he's humping her so much that she feels good through her clothes? No, it must be acting, right? Just to arouse him more so he releases faster? Yeah… Yeah…'

…

Interestingly enough, the thought that Rias was moaning extra hard to please another man did almost nothing in terms of improving his emotional situation.

Before turning the corner, Issei looked back one last time.

Koneko was peeking through the door.

…Rubbing her legs together.

Issei was not able to get a moment in with Rias, forced to leave for school with everyone.

"Nghhhh ! Mnghhh ! Uuuungh !" Again and again, the moans kept playing out in his head.

Rias had never made ANY sound close to that with him.

Was it because Marcus was 'physically superior' to him? 'No way… Rias doesn't care about that! She loves me for who I am and my personality… Girls don't care about looks or muscles… Or penis size or anything like that! Even if they did, Rias is special. Like Akeno! And Koneko, and Xenovia, and Asia! Hell, even Sona! Khh…'

It really was a mistake for him to ask Koneko for details.

Now, he was stuck thinking about his beloved Rias being crushed under the bed by the enormous black man, getting dry-humped with so much ferocity that her body got repeatedly dug into the mattress, bouncing up and down due to Marcus' ridiculous build. 'What would she be wearing…? Just panties…? Shorts…? A skirt…? But with his dick being that big and hard, does it matter?! It'll push through anything, meaning she'll feel it directly against her-… Nghhh… No, that can't be it… Maybe he was just humping against her shirt… Yeah…! Like her stomach! That's not as bad… And then… And then…'

And then, whenever he reached release, his semen would rain all over her midsection, chest, and likely face.

Issei did not feel any better about that interpretation of events.

For hours, with fake moans or not, his voluptuous ex-girlfriend was smashed under the large, large man, likely disappearing from view if seen from above.

How was Issei supposed to cope with-

"Yo, did you hear that thing about Rias?" A student said to another behind Issei in class.

"No, what about her?"

"Some guy said she saw Rias going up to the rooftop with that new foreign student."

"The black guy?"

"Yeah, that one. You think she's doing something with him?"

"Rias…? Man, she's so hot… She does have the kind of body to match up with a man that big. Is Rias a size queen?"

"Wanna go check?"

"No fucking way. The rooftop's off-limits, and Sona's a bitch. She'll kill us if we get caught." The student was a coward.

"Yeah, you're right." So was the other.

…But Issei was not.

He fled class by claiming to need to use the bathroom and rushed to the rooftop. If he found Rias there – with or without Marcus – it would be his chance to talk to her and solve their messy situation!

Just as he meant to open the door to the rooftop…

"Issei!"

"Huh? Asia?" The blonde girl grabbed onto his arm at the last second. "What are you doing here?"

"I was coming out of the bathroom and saw you running with that look on your face, Issei! I got worried. Is everything okay…?"

"You shouldn't be here…"

"Why? What's going on?"

"I… Heard that Rias was here on the rooftop, so I came here to talk to her…"

"Isn't she with… Uhm… Marcus…?" Asia blushed. Merely mentioning the man invoked the memory of the animalistic thighjob that took place in the club room yesterday.

"…Maybe. I want to talk to her either way. Even if they're doing something, I'll interrupt them to talk to her."

"Okay…! I'll join you, Issei! I'm worried about her too!"

Issei did not want Asia there, but it did not look like she would accept leaving, so he resigned.

He opened the door to the rooftop and crossed through with Asia closely behind him, holding onto his arm.

"Ngh… ! Mngh… ! Ughn… !" Their ears were instantly invaded by feminine groaning and wet squishing coming from nearby.

Not just that, but… "Khhh…! Ghhh…! Master…! I'm about to…!" …Also deep, masculine grunts that implied strenuous physical effort.

It did not take much thinking for Issei and even Asia to realize what Marcus was implying.

"Go ahead… ! Ghnn… ! Mngh… Don't hold back, please… ! Nghhh ! The more you let you… ! The better you'll feel… ! Ooh ! You're thrusting ! So hard… ! Against my boobs… ! It's rubbing a lot against my nipples… !"

"I'm sorry…! I'm sorry…! Grrr…! Ghhh…! I'm losing control…!"

"Don't apologize…! Mnghh ! My nipples are sensitive is all… ! And it feels a little good too… ! Keep going… ! I won't let you suffer again… ! Milking you with my breasts… ! Is… ! My… ! Responsibility… ! Nghhhhhh… !" Rias' voice suddenly got tense, with her words turning into nothing more than senseless groaning.

"Pres- Whoah…!" Issei was thrown off-balance by Asia speeding up past him to peek around the corner. "H-hey…!" Just as Issei tried to peek over the corner too, she pushed him away.

"Don't look, Issei…!" Asia shook her head frenetically.

"Nghhh ! Mnghhh !

"Wh-why not?"

"Ghhh! Khhh!"

"Don't look! I'm serious! It's… It's not good." She blushed with accelerated breathing.

Issei had no doubt that Asia meant well, but he did not care – And Asia did not have Koneko's physical strength to be able to stop him.

He gently moved her out of the way and peeked.

'…' Indeed, it was a mistake. After only a second of looking, Issei backed away from the corner.

Rias was pressed against the wall on her knees, crushing the sides of her boobs with her closed hands to smash them together around Marcus's monstrously-sized black cock. It was so big that half of its veiny, soaked length still popped out of her cleavage, forcing her to move her face slightly to the side; The alternative would have been to suck it deep into her mouth, and it was questionable whether any woman could do that without dislocating her jaw.

What was the worst part…?

Was it the fact that Rias was just kneeling in place while the muscular man brutally pounded her tits as if they were a cheap sex toy, repeatedly flattening them due to his bulky legs and bruising her abdomen to his low-hanging, heavy balls?

Was it the look on her face, with her tongue dangling out as she breathed heavily from clear arousal, waiting for a load to shoot onto her face and boobs like a good girl?

Was it the small puddle of vaginal fluids accumulated on the floor, implying she enjoyed the rough treatment of her breasts and nipples to the point of orgasming into oozing sex juices?

Was it the fact that her face, hair, and chest were covered in cum, meaning they had been going at it for a while and showed no signs of stopping?

"You're so strong and handsome, Marcus… ! I love seeing your abs dripping with sweat as you do it… ! Keep going… ! Use my tits… ! You're doing a great job… ! They're pillows to please your big black cocks, so focus on enjoying their soft sensation… !" Was it the fact that she talked dirty in the gentlest of ways to stimulate the giant black brute into fucking continuously hard the boobs that Issei loved so much?

Maybe it was one of the above.

Or, maybe, it was the fact that Asia took a while to catch up to him even though he was walking at normal speed.

…Why did she lag behind?

Issei's motivation during their PE class – today was swimming – was non-existent, simply going through the motions.

Was Rias still on that rooftop, letting Marcus maul her chest for sexual gratification?

She was no masochist as far as he knew but was willing to let her body be abused for the large man.

More than that: She seemed to have orgasmed. 'Maybe… Rias likes him because he's stronger and taller than me with a bigger dick…' It was hard not to feel inferior when seeing the feminine reactions coming out of her face and voice for a man who was treating her so roughly. 'I KNOW that if I tried to be that rough, she'd hate it… But for him, it's okay…? Is it all just to please him because he's a Black King piece… Or is it because she likes him for being bigger and stronger? How much can Rias fake it…?'

Regardless, even in his downtrodden state, Issei noticed something curious during swimming class: Xenovia – who never ever stopped exercising during PE – had just left the pool to talk to Sona.

'What's Sona doing here…? They look like they're talking about something important…' Issei got out of the pool and peeked from a corner, hoping to spy.

"Right now?" Xenovia asked Sona.

"Yes. I'll deal with the consequences of you skipping class. Just go help Rias in the Student Council room."

"Alright, sounds like a challenge! Let me just get my phone."

"Don't take too long." Sona left.

'Help Rias in the Student Council room…? What does that mean-"

"Oh! Issei. Were you spying?" Xenovia bumped into him upon turning the corner.

"Yes!"

"Wow, you admitted that super easy-"

"What did Sona tell you? Does Rias need help?!

"Damn… You're not even staring at my boobs. You must be worried sick about Rias, huh…?"

"Yes! I need to talk to her alone…!"

"Well, maybe after I help her a bit, you'll be able to!" Xenovia raised a fist in support of his feelings.

"Why did she ask you to help Rias?"

"Sona thinks I might be resistant to his semen because I used to be an angel. Plus, I bet Rias is having a hard time since Marcus is so virile and has lots of stamina. He has that huge dick and it's super thick, so she might be having trouble handling it all on her own. Oh, but Rias didn't ask for it. It was Sona's idea because she's worried about her… I guess Rias is doing her best but it's still not enough. It makes sense when you consider the size of that guy's balls!"

"B-but…"

"Oh, sorry. I guess it's a sensitive topic for you, huh…? You guys were dating and kissing just a few days ago, and now she's using that same mouth to kiss the dick of a guy three times your size…"

"Wh-what?! She's blowing him?!"

"Hm? I thought you knew. Th-that's what Sona told me at least… She wanted me to help her blow him because Rias' jaw is getting tired."

Issei wanted to snap in rage but was too crushed from the continuous emotional beating.

"Hey, it's okay, Issei! I'll do my best!" She grabbed his shoulder and gave him a thumbs-up with a big smile. "I'll suck really good!"

"S-suck really good…?"

"If I do a good job and that guy finally gets his balls emptied, Rias might have some free time to talk to you, right? You can convince her to find some other solution then!"

"Oh! Okay… That is a really dirty way of helping, but if that works, I'll take it!" Issei was so desperate that he did not mind sacrificing one of the members of his future harem to recover Rias. 'Even a Harem King must make sacrifices sometimes! And it'll be just this one time. Xenovia won't get affected by his semen from just one time blowing him, right?' His mind paused. '…Ghh… My pride is basically gone, isn't it…?'

"Alright, leave it to me. I'll go all-out sucking that guy's huge black dick to help you out! I promise Rias will be back to you by evening!"

"O-okay…! Alright, do it, Xenovia! I believe in you!" Issei felt like an idiot for what he was praising. "But… Uh… Be careful."

"Don't worry. I won't change or anything just because I give him a blowjob. I got this." She moved past him to leave-

"Ah, wait, Xenovia. Just one thing..."

"Yeah?"

"Why are you doing that?"

"Doing what?"

"That." Issei pointed to his own mouth to get her to think of her own mouth.

She did not understand.

"You've been licking your lips the entire time we were talking. It's a little distracting."

"I have?" She touched her own mouth – apparently, she had been doing so unconsciously. "Oh, that's weird. Wonder when I started doing that? Thanks for letting me know." She left.

It was a good question.

When had she started doing that?

'It was after Sona talked to her, I think.'

…

'Yesterday, she drank a little of Marcus' precum…'

…

'It's fine. I doubt it means anything.'

It was already evening and Issei did not see Xenovia or Rias again. 'Neither one is taking my phone calls… Could they still be in the Student Council room…?'

…

'Giving that guy… A double blowjob…? N-no, there's no way. I bet Xenovia misunderstood something too. Rias would never give that guy a blowjob in the first place!' It was hard for Issei to imagine and accept a reality in which the lips he kissed so often were now running along the length of Marcus' massive black penis, rubbing against every single vein while being coated in viscous precum – and possibly cum… AND possibly drinking it. 'He shot so much on the rooftop and was still hard… If she shot that much in her mouth, wouldn't she choke?! And it's so thick too, so it's gotta taste AWFUL! President always drank my semen when she blew me, but I could see it on her face that it did not have the best flavor. That guys' must be ten times worse!'

Perhaps worse, it was hard to imagine that the man who invaded Issei's life was now receiving a DOUBLE blowjob within a day of rejoining Rias' peerage. Even while dating both Rias and Akeno, Issei never received oral service from both at the same time due to reaching ejaculation far too quickly each time, ruining his erection – and there simply was not enough penis length available for two lips. 'Getting blown by two hot girls at the same time…? After spending the morning with President, and after getting a boobjob on the rooftop?! How many times can that guy go…?! Grr…! All this because he's got that big body and big dick…?! I can't accept this…!'

Moved by fury, he rushed over to the Student Council Room, aiming to be proved wrong.

In front of it, he found Sona standing with her back against the wall, bored. "Hm? Rias' pawn? What is it, Issei?"

"Wh-where is Rias…?"

"Inside, serving the Black King piece with her mouth." Sona was upfront as always; Too upfront. "Your Knight friend, Xenovia, is doing the same."

"B-both… At the same time…?"

"The dream of many men, isn't it? Black Kings are energetic…"

Sona Sitri was a short – 5'5 – slender woman with a bob-cut style black hair with blunt bangs on the front and violet eyes. Her ass was perky and her breasts were B-cups, giving her an overall slender and refined look. She acted as Student Council President of Kuoh Academy and was a High Devil with her own peerage, standing as Rias' rival and childhood friend. She rarely lost her cool, and imposed authority on her pieces with much more harshness than Rias, able to maintain a cold, rational outlook on things at all times – for better or worse.

"Why are you here, Issei? You wish to get inside and stop Rias?"

"I… I can't accept what's happening! She's using herself as a tool to please him!"

"I agree. We should have killed him."

"What?! No, that's not what I'm saying! No one is talking about killing him!"

"No? Then what ARE you saying?"

"That… That we should have found another way!"

"There is no other way. Are you a child? It was either kill him or let Rias objectify herself into a living sex toy for his eternal gratification. It must be bad for you as her boyfriend, but I'm sure she'll learn to enjoy it."

"E-enjoy it?! Are you nuts?!"

"Are YOU nuts, Issei? Haven't you realized it yet? The Black King's piece instills its devil with an uncontrollable urge to procreate. How does it ensure that the procreation occurs? By continuously enhancing the devil's body with masculine traits that attract and easily satisfy women. In general, females feel a strong allure to tall, muscular men. The presence of a large, thick, odorous penis adds even more to that effect. A man like Marcus only needs a single time with a woman to make her sexually dependent on him… And that's even before accounting for the powerful effects of the semen. It will grow the bodies of the women he breeds with and make them highly addicted to sex with him. In essence, the Black King is cursed to build a harem and spread his seed, whether he wants it or not. Hm? Why are you looking at me that way?"

"…"

"Oh. I've rambled a little, haven't I? I just heard so many girls ask me who the new student was and if he was single, it gets tiring. The point is, you're out of your mind if you think Rias won't relish in the greatest pleasure possible to a woman by having sex with him. Even sucking him is likely far better than sex with any other man on Earth, especially a chump like you."

"I-I'm not a chump! And Rias loves me…!"

"Well, love is great, I agree. But in terms of pleasure, physical exceptionalism is far greater. You can have Rias' heart while Marcus THOROUGHLY has her body. Does that make you feel better?"

"I don't believe anything you're saying!" Issei stood his ground, even if shaken up by Sona's willingness to so heartlessly explain 'reality'.

"You don't NEED to believe it. Either you defend that Marcus should die, or you accept that Rias is gone for you, at least sexually. Sorry if that hurts your feelings. Honestly, at this rate, it's going to be more than Rias, and it's starting to worry me…"

"What is that supposed to mean?!"

"It means that she's holding back far too much. Using her mouth to blow him into satisfaction…? That's ridiculous. That man will not be sated until he has hardcore breeding sex with her or other women. The masculine fulfillment of knocking up a beautiful woman… That's what he needs. Everything else is just palliative. He needs raw penetrative sex with plentiful internal releases. Whether the impregnation part matters, I don't know. Not much is known about the curse… But it is not as if birth control works against sperm that strong, so who cares?"

"Y-you're wrong…! There's no need for things to go that far!"

"Yes, there is. Rias will realize that soon too. I just hope she does it soon enough that I can relax about him possibly infecting my peerage's women with his big black cock. Killing a devil of another family is frowned upon, so I don't know what I'll do in that case. Maybe I'd have to start letting him breed me…"

"Then why don't you do that now?! You don't have a boyfriend, right?! You could keep Rias from having to do this! Aren't you her childhood friend?! T-take Marcus as your boyfriend if sex with him is so great!"

"It's a possibility under consideration." Sona bluntly announced. "He IS attractive and sexually powerful. The appeal is self-evident and even I feel drawn to it."

"So… So do it!" Issei thought he had found a lifeline.

"Hah… I'm not sure yet. Like I said, not much is known about the curse, and I THINK his seed might have some effect even in High Devils. I am afraid of how depraved I might become, or how my body might develop sexually… Sorry, Issei. It's Rias' responsibility. She chose to save him, so she has to be the one bouncing up and down on his penis now. Don't take it the wrong way, but you'd be happier accepting that he'll knock her up and use her regularly as a sex toy from now on. That's what Rias is willing to do to protect your peers from becoming breeding sows."

"Grr…! If that's the case, why'd you ask Xenovia to help?! Huh?! Didn't you just compromise her?!"

"As an experiment. She has a past as an angel, which is unique among devils. Maybe she is able to handle him better than most? Honestly, I doubt it… But I had to try. I'm not one without empathy. Rias needed the help. She's holding back too much, which is just tiring out her arms… Boobs… Jaw… She had bags under her eyes when I saw her go in with him, and it hasn't even been a full day yet. At this rate, she'll physically collapse, and Marcus will run loose with unsatiated urges."

"Then let me talk to her! I'll convince her to rest a little…!" He absolutely did not mean that sentence – his goal was to talk her out of it somehow. 'There has to be a different way of helping Marcus! I know it!'

"No. If anything, you'll make it worse. This is your fault, Issei. You're the reason she's holding back."

"What…?"

"Because her heart belongs to you, she can't bring herself to go ahead with letting him penetrate her… So she's doing just about everything else, which, like I said, won't work. If you go in there, you'll just remind her of her love for you and she'll hesitate even more. She needs to accept penetration as soon as possible."

"If… If that's true, that's all the more reason for you to let me talk to her right now!"

"No. In fact, it'd be smart of you to start letting go, for her sake and yours. I preemptively apologize."

"Apologize?! For what-"

"For this." Sona raised a hand and gestured to cast a spell.

"Ghluurgh ! Shluuurp ! Ghluuurgh ! Bhrluuuurgh ! Shluuuurp ! Ghluuurgh ! Shlrrrrrp ! Bhluuuuuurgh !" Aggressive, desperate sounds of gagging and gurgling started leaking through the door behind Sona.

The entire time, Sona had been keeping the room soundproofed, as Koneko did in the morning.

Now that she removed the spell, the truth behind the door made itself known.

"Ghurgh ! Shluurp ! Shlrrrrp ! Brlhuuuuurgh !" …And it was loud, nasty, and scary.

"Wh-who… Who is… That…?"

"Could be Xenovia or Rias. I don't know-"

"Let me take over, Rias! You've been going for a long time! It's too much for just one mouth…! Let me… Hah … Let me suck and drink a little…! To give you a break…! The shaft is great, but I wanna take the tip a little…!" Xenovia pleaded with a breathless voice…

"Ghluuuurgh ! Brhluuuuurgh ! Shluuuuuurp !" …Making it obvious who was gurgling so frantically.

"See what I meant? Do you really want to kiss those lips again?" Sona looked him straight in the eyes with an aloof expression. "…Let go."

Issei would definitely not let go; He could not. Regardless, demoralized as he was, Issei had no choice but to retreat. "I-"

"Hm…?" Sona looked back at the door for a moment. "Oh, it's happening again…"

"What is…?"

"Listen."

"GHLURGH ! BHLURGH ! SHLUUUUURP ! GHLUUUURGH ! BHHLUUUURGH ! GHLUUUUUUUUUUUUUUUU-" The desperate gurgling abruptly stopped after Sona made another gesture – she used the spell again to cut sounds off.

"Marcus entered another frenzy."

"Frenzy…?"

"Yes. It happens when he starts…" She stopped and averted her gaze – a small sign of empathy amidst her cold exterior. "…Releasing. He grabs her head, or Xenovia's head, and… Well, I suppose the best way of describing it would be that he facefucks them and releases an extensive load directly down their stomachs by deeply penetrating her-"

"Stop! Just… Stop… I… I can't listen anymore." He hunched forward and supported himself on his knees; Issei could feel vomit and tears coming.

"…Issei." Sona rested a hand on his shoulder and leaned forward, bringing her face level with his. "…Let go."

Suddenly…

"GHLUUURGH ! BHLUUUUUURGH ! SHLUUUUUURP !" …He started hearing Rias getting brutally facefucked again – it was clear from the frantic sounds that she was being made to chug down an absurd volume of semen.

"Wh-what are you doing?! Soundproof it again…! I don't want to hear that!"

"Hm? It IS soundproofed. There's no sound coming out."

"What…?" Issei looked at the door.

Indeed, there was no sound.

"You imagined it because of how shaken up you are. You're crying, Issei." She used her sleeve to wipe off his tears. "Akeno still loves you and will remain with you as long as she doesn't get tainted by Marcus. Cherish her and let Rias do her duty as your peerage's master, alright? Try not to think too much about it either… And absolutely do your best to avoid Rias whenever she is busy with Marcus. You get why, don't you…?"

"…No… Why…?"

"Because I promise that whatever sounds or visuals you imagined…'

…It was likely much rougher in reality.

"Issei… Oh, my, you're starting to make me jealous." Akeno taunted Issei by rubbing her large breasts onto his face, trying to get his attention. "Here I am, offering you the funbags you so love to play with, but you're still sad about Rias? Am I not enough for you…?" She whispered in his ear with a sweet voice.

It was night. He was in bed with a naked Akeno but could not get hard again. "Sorry…"

"Hm… It's fine… I get that it's a rough situation for you, but you'll have to get over it. The situation is better than you think."

"How is it better?!" Issei snapped at Akeno – an abnormality, considering his love for her, her high ranking as Rias' Queen piece, and their usual dynamic: Akeno was easily the most dominant of their throuple. "Rias is getting used like a prostitute to- Ghh! Wh-what was that?!"

"Oh, my." Akeno had poked his nipple with a finger and shocked it mildly – something easy for the Priestess of Thunder. "That was a cute whimper. You were getting a little rowdy, so I wanted to scold you… But it had a bit of an effect down here, didn't it…?" She ground against his lap. "Should I just tase your nipples until you give me a big, nice boner to milk…? Then, I can be the Rias to your Marcus, hmm…?"

"D-don't say it like that…!"

"Why not…?" Akeno rested her torso against his, warming his chest with her big frontal mounds. "…She's having tons of fun sex with him right now, I bet… He's feeling super good, releasing lots and lots of cum… So, while they're there having crazy sex, we should have crazy sex too. What do you think…?" She sucked on his neck until it was marked with a bruise – a hickey for later – and moved her lips to his ear. "…Doesn't that sound good…?"

"I-it's not that easy for me…"

"Is it because you're not as manly as him…?"

"Wh-… What did you say…?" Cold sweat formed on Issei's forehead.

"Marcus is always ready to pound a tight, sexy girl… So, is it because you're not as manly as him…? I bet if Marcus were here, he'd be shredding my small hole with his huuuge cock… He's so much bigger than me, so I'd be in real danger. It's hot, though, isn't it…? I bet the pleasure I'd feel from his big black cock pouring baby cream inside my womb is magnitudes greater than what you can provide with your soft penis, Issei… I'm starting to get jealous that Rias is there, having fulfilling sex that makes her feel like a woman while I-"

"STOP THAT!" Issei pushed her away. "What are you doing, Akeno?! Why are you talking like that?!"

"Oh, my!" She smiled. "You didn't like that, did you…?"

"Of course not!"

"My bad. I thought that maybe you had an inkling for being cuckolded, so I was just trying to stimulate you. I didn't mean any of it, okay?"

"Why would you think I'd like that?!"

"Because I'm right here, naked and offering myself for you, and all you can think about is Rias getting railed and bred by Marcus' big black cock and body." Akeno did not hold back whatsoever; There was hidden frustration within her voice – and explicit frustration within her words. "I apologize. I understand your feelings. It's only been a day... It's not reasonable of me to expect you to get over her so quickly. Just a while ago, you had TWO women with big titties tucking you into bed, and now you have only me… Oh, my, what a victim!"

"Y-your sense of humor is dark, Akeno…!"

"Like Marcus' big black cock?"

"Stop!"

"Oh, my! I'm pushing too much. Sorry, sorry…" She lied beside him, put her face against his neck, and closed her eyes. "Why don't we sleep, then? We don't need to have sex EVERY night."

"Y-yeah…"

…

"You know, Issei…"

"What…?"

"I know you might feel sad, but you should be a little happy…"

"Why…?"

"Rias is sacrificing herself to keep everyone safe. The reason you get to enjoy daily life with tons of beautiful devil girls giving you all sorts of attention is because of her efforts. If she were not doing what she's doing right now… Well… You know…"

"'You know' what…?"

"Just be thankful for what you have. You might miss it someday."

Akeno said something weird.

The next day, Issei remained unable to talk to Rias all day due to her 'duty'.

Nevertheless, he was hopeful that an opportunity would appear in the evening: Rias proposed that they all go to a karaoke bar after school so Marcus could bond with everyone.

…It did not work too well.

Though everyone was in the same small room, eating and taking turns singing – with varying levels of bad – there was barely any talking or bonding due to palpable tension in the room.

Asia, sitting close to Issei, could not look Marcus' way, blushing nonstop.

Koneko was the opposite, unable to look away. Her eyes glued to Marcus without blinking, like an obsessed cat.

Xenovia seemed mostly herself, maintaining an energetic, carefree demeanor… But she could not stop licking her lips for some reason – way more than yesterday.

Kiba was mostly himself, but he kept glancing back and forth between all the girls.

Akeno was the only one who remained the exact same, sitting beside Issei with a possessive hand on his leg and a constant devilish smile on her face, teasing him with erotic whispers every now and then.

Issie himself was deeply, deeply anxious.

How else should he feel when looking at the Rias on the other sofa, sitting beside Marcus?

She looked drained. There were visible bags under her eyes. Because they went there straight after school, she lacked the time to take a shower. Her hair was slightly disheveled and oily; Her body was coated in a thin layer of dry sweat; Her uniform was slightly bunched up and stained in multiple spots; Her nipples popped out more than usual through her clothes; And there were constant streams of vaginal fluids running down her skirt, dripping onto the floor.

Anyone could look at her and tell that she had barely been sleeping – if at all – due to how extensively and committedly she had been satisfying Marcus. Perhaps it was due to those strenuous efforts that they were able to hang out at the karaoke room that evening.

And yet… '…He's still hard…!' Issei was frustrated by the man's ridiculous superiority in terms of erection power. 'She's been helping him release load after load since yesterday, and he's still hard!'

Marcus did not look as drained as Rias, but the signs of physical exertion throughout the day were visible on his veiny arms and somewhat sweaty clothes. His penis remained fully hard inside his pants, throbbing wildly. No doubt, if given freedom, it would spring up and stand at full mast, ready to be serviced with plenty of veins drawn across its length.

Its size and throbbing were not the main attention-drawer, though; It was the growing smudge at its tip. Even without any direct stimulation, it was oozing endless precum, lubing itself up for the act of sex to the point of staining his pants from the inside – and then some. Some drops of it ran down the full leg of his pants, creating a tiny puddle on the floor, beside Rias' small puddle of vaginal juices.

…It did not take long for the reek of dry sweat and sexual desire to oppress the room.

Funnily enough, Marcus seemed the most nervous of all, unable to maintain contact with anyone.

Eventually, Marcus stood up because it was his turn to sing.

But instead of singing… "Everyone! I'm so sorry! I'm so sorry! I hate this!"

"Marcus?!" Rias was shocked. "I-it's fine, it's not your-"

"It IS my fault! I'm so sorry! Because of who I am, the dynamic of everyone's lives became bad! I hate myself for it…! I hate my body…! Sometimes I wish I were dead! But Master Rias is so kind and wants to protect me even though I am making her life a living hell…! If I could do anything to get rid of this curse and this disgusting, ugly body, I would, but I can't, so… Please… Forgive me…!" Almost in tears, he gave everyone a bow – a true one, unlike the small hunch of the other day. "I know it's difficult…! And I know I'm to blame for causing so much trouble…! But I would love to become friends with everyone someday! I'm sorry!"

His abrupt apology was so filled with clear, honest emotion that everyone was stunned.

…Or was it because of his pants straining to hold his throbbing erection in? Standing and bending like that threatened the integrity of the fabric due to its sheer power.

After a long period of silence, Rias-

"Hey, it's fine, Marcus. We all know you're a good guy. I know it's rough, but we've all got our circumstances… If it counts for anything, I like you. And we had a good time yesterday! Let's be friends." Xenovia said with a bright, lively smile – still licking her lips.

"Yes. Rias saved us all. There's nothing wrong with her saving you. Sex is normal. Let's be friends." Koneko supported him with her cold voice – still staring at his bulge.

"Y-yeah…! She saved me too and Issei almost died in the process! I would never hate you! And you're not ugly! You're handsome! L-let's be friends!" Asia said – still unable to look his way, blushing.

"You're one of us now. I tried to leave one time too and got everyone involved in a huge mess, but Rias accepted me back anyway. You're not the first one to screw up. Let's be friends." Kiba also supported him – still moving his eyes between every girl.

"If anything, it is Rias' fault for being so overbearing. I think she likes you, Marcus. Must be nice to be so strong and masculine. The sexiest babes just come for you. Let's be friends." Akeno teased him – still the same woman as ever.

Rias' and Marcus' eyes brightened up due to everyone's warm reactions. They clearly did not expect such a positive outcome, helping Marcus to feel included in spite of his disruptive situation.

The only one missing was Issei.

Rias looked his way, hopeful that he would join everyone.

"…" …But all he did was cross his arms and look away, pouting.

"Ah…!" Marcus gasped upon seeing Issei's reaction, with tears beginning to roll down his face. "Of course… I ruined… Master's happiness with you… I'm so sorry… I can't be forgiven- Ghnnn!" He abruptly groaned in pain and grabbed his crotch. "Khhh…!"

"Marcus!"

"M-Master… It's a friendly hangout…! I don't want to…! Ruin it…! Please, ignore me…! Please…! Khhhh…!"

"That's ridiculous. We'll deal with it right away." Despite her visible exhaustion, Rias was ready to act. "My apologies, everyone. We'll be right back. Come, Marcus." She slowly and gently stroked his protrusion as they walked out of the room.

"H-hey, this is a joke, right…? I thought President would finally have some peace…! Even here…?!"

"It's your fault, Issei." Akeno said with a smile – as always.

"Mine?!"

"It's clear that he cares about your opinion. Marcus trusts Rias, and you're important to Rias, so… You could have been more understanding."

"So?! How does that make it my fault?!"

"Stress and anxiety make the curse worse. This was already said, wasn't it? Maybe if he didn't feel as guilty and sad, he wouldn't need as much sexual attention."

"A-are you saying she's been helping him for almost two days straight because of me?!"

"Yes." Akeno bluntly announced.

Issei did not expect to be directly assigned blame. He looked around the room for support.

Koneko and Kiba said nothing.

Asia was still too busy blushing nervously.

"Hey, don't look at me. I don't know anything about this stuff." Xenovia had nothing deep to add, still licking her lips.

"W-what a joke… President is getting that guy off right now because of me?!"

"Issei. Let me be clear." Akeno grabbed his hand and looked him directly in the eyes from up close. "Right now, Rias is using her body as a tool to sexually relieve him BECAUSE of you. You have all of us as friends, and me as your girlfriend, but your obsession with Rias is making things worse for her. And, frankly, for you too. Did you get it this time, or was I too vague?"

"T-tch…" Issei crossed his arms and looked away, too stubborn to concede. 'It's not my fault. Of course it isn't…! I'm just looking out for Rias…!" He strongly rejected Akeno's claim.

…Nonetheless, Rias WAS sexually relieving Marcus, his fault or not.

'She's been gone for over 20 minutes…!' Issei could not take it anymore. 'I'm gonna check!'

"Issei? Where are you going?" Akeno asked.

"To the bathroom. I need to pee."

"Oh, my. To the bathroom, hm…? I should probably stop you."

"Please, don't."

"…Well, there's no point, is there? Maybe you'll finally get the wake-up call you need. Don't come crying to me if it's too bad, okay?"

"He needs to pee that badly?!" Xenovia was surprised.

"It's bad to hold it in, Issei!" Asia offered essential support.

"I'll go with you, Issei." Koneko got up and volunteered herself.

"Uh… I can pee on my own."

"No, you can't. Let's pee together." Koneko forced herself to his side and grabbed his hand, leaving him no choice.

"It's THAT bad?!" Xenovia was even MORE surprised!

"Do whatever you need to get your pee out, Issei, Koneko!" Asia offered even MORE essential support.

"Y-you guys…" Kiba struggled with everyone's lack of awareness.

"Let's go pee, Issei."

'You've got to be kidding me…' Issei left with Koneko. "Why are you going with me, Koneko?"

"To make sure you pee inside the toilet."

"Can we stop with that?! You know I'm going to check on Rias."

"And I want to keep you from doing anything reckless. Anything more than what you already did, that is. Marcus isn't a bad guy, you know? He's going through a tough time."

"Grr… I don't care."

"You should."

"…" Issei added nothing.

They headed for the female bathroom, where they assumed Rias and Marcus were.

Indeed, they were correct. By simply entering the bathroom, they knew they were there.

"Shlrrrrrp ! Shluuuurp ! Shlrrrrrrp ! Shluuuuuurp !" …It could not be more obvious.

"Th-that smell…" Issei whispered, wincing from the worst stench of his life. "What is that…?!"

"Let's find out." Koneko was seemingly unaffected by the stench, rushing inside the stall neighboring the one that Rias and Marcus were in. She climbed the toilet and looked over the stall separation.

Issei was surprised that Koneko was so eager to look when her only goal was to keep him from doing anything bad, but cared too little to question her, climbing the toilet to look-

"Don't." Koneko tried to stop him.

"Why?"

"You'll regret it."

"Shluuuurp ! Ghluuuuurgh ! Shlrrrrrrrrp ! Shluuuuuuuurp !"

"…I don't care." Issei could not ignore the sounds. He evaded Koneko's hand and looked over the stall.

His shock was infinitely greater than on the rooftop yesterday.

Seeing his beloved Rias giving Marcus a sloppy boobjob was one thing…

…Seeing her face buried into Marcus' ass, giving him a sloppy rimjob was another.

Rias was on her knees with her nose shoved between Marcus' muscular glutes, licking up and down his asshole with one arm around his hips to aggressively stroke his SOAKED enormous cock and another between his legs to massage his balls as if to pump the cum out of him.

"Shluuuuurp ! Shlrrrrrrp ! Ghluuuuuurgh ! Bhluuuuuurgh !" Her oral technique was so sloppy and fervent that thick, slimy strands of spit dripped down her chin whenever she stopped to take a breath.

"Shlrrrrrrrp ! Bhluuuuuurgh ! Shluuuuuurp !" Tears ran down her eyes from the smothering effect of being so dug into the man's asscheeks, compromising her ability to breathe.

"Shllrrrrrrrrp ! Shluuuuuuurp ! Shlrrrrrrrrp !" Even when she was not eating his ass, it must have been difficult to properly take in air. After all, their small stall was SMOTHERED in the reek of musk and sex.

The stall door in front of Marcus was almost completely covered in semen.

It was so viscous and sticky that it glued to the door like gum, slowly streaming down to form puddles on the floor.

In only 20 minutes, Rias had licked his ass and stroked his massive black cock with enough ferocity to release enough semen to cover almost the entire door.

And yet, Marcus remained hard enough to need dedicated service.

'What… Is this…?' Issei had never received a rimjob, nor did he want one. 'I love Rias too much to ask for something this degrading! Licking a man's asshole?! That's humiliating…! How could he ask for this?! How could she say yes?! There's no reason to pity this guy! I hate him…!'

"Shluuuuuurp ! Shlrrrrrrrp ! Hah … Hah … Hah … Marcus… Is it feeling good…?" She continued to aggressively jerk his wet, hard cock while taking a breath and speaking. The hand she used to stroke his penis was drenched in cum and precum.

"Yes…! Ghh…! But you don't have to keep doing it if you don't want to, Master…! Khh…!"

"It's fine. It was my idea… Hah … Hah … It tastes good, actually… You have a good body, Marcus. I'll keep going, okay?"

'What…? It was her idea…? Huh…? Just to get him off…?'

"Shluuuuuurp ! Shlrrrrrrrp !" Rias got right into it, barely waiting to fully catch her breath.

And then, something even more astounding happened.

Rias stopped massaging Marcus' balls to free a hand.

…To touch herself.

Issei watched in slow motion as she slid the hand into her skirt and began fingering herself.

There was no way THAT was to get Marcus off. 'Is she… Enjoying doing this…?'

"Mnhhm … Hnmm …" All of a sudden, Koneko let out small whimpers beside Issei; Her legs were rubbing together at a fast pace, watching without blinking.

"Wh-what are you doing…?"

"Hm? O-oh, nothing…" She stopped herself.

Issei once more looked at the action. 'Ah…! She stopped touching herself! I-it was just a moment of madness!' He felt a little optimistic.

Then, Rias moved the free hand to Marcus' penis, getting it coated in a thick layer of cum and precum.

…And then she brought it back under her skirt.

"Nghhh ! Shluuuuuuurp ! Shlrrrrrrp ! Mnghhh !" Rias had only pulled her hand out to get his sex juices on her fingers.

Was it as a form of lubrication, or was it because she wanted to feel his semen inside her vagina, sticking to her walls?

Whichever the answer was…

"Nghh… ! Shlrrrrrrp ! Shluuuuuuurp ! Unghh… !" …The effects were immediate, leading her to rock her hips back and forth on her fingers while continuing her dedicated ass-eating session, licking and jerking devotedly. Her uniform was ruined with sweat, along with her disheveled hair and messy face. Her neck was red and tense with veins from physical exertion and insufficient breathing. And yet, she carried on licking and breathing the heavy air.

Right as Issei thought things could not get worse, something happened: Marcus started spasming and grunting like a maniac.

"Grrrrrr! Ghhhhh! Khhhhhh!" His cock spasmed out of the control of Rias' small hand, escaping its grip to swing left and right, up and down, shooting dense jets of cum all over the door, and even under and above it. A couple of times, it even hit his own abs, bruising his skin.

It was the craziest thing Issei had ever seen in his life, looking like a psychotic beast out of control, trying to free itself from his body in frenzied orgasmic release. The popping muscles and veins throughout his skin were a clear demonstration of the physical strain he felt each time he ejaculated.

Throughout all of it, Rias continued to devour his ass, aiming to extend his release window and pleasure.

For her own sake? For his sake? Or for her enjoyment…?

The last option became oddly realistic when Issei realized Marcus was not the only one cumming.

"Ghnnn ! Shlrrrrp ! Mnghhh !" Rias' body was quivering and spasming too, with gushes of vaginal juices coming out so intensely that her skirt was stained from the inside and her inner legs were ruined with renewed volumes of the fluid.

'I can't… Watch this anymore…' Whatever drive Issei had was decimated. 'She… Orgasmed… From giving him a rimjob…? I can't… I can't…' He backed off from the edge and got down the toilet. "Koneko… Let's go…"

"…" She was intently observing Rias and Marcus, sniffing constantly.

"Koneko…?"

"Hm? Oh. Yes." She got down from the toilet and followed him out of the stall.

Issei held the door to the bathroom open for Koneko to pass.

…

"Koneko?"

"I need to pee."

"Huh? This joke again?"

"No. I really need to pee, so go ahead without me." Despite maintaining her stoic look, Koneko was blushing an unusually intense shade of red.

"I can wait. Or use the male bathroom."

"No. I REALLY need to go now. It'll take a while."

"Why-"

"Issei. Go. Please." Koneko glanced at Rias and Marcus' stall. "I'll… Be right there…"

"Shlrrrrrp ! Shluuuuuurp !"

"O-okay." Issei left with a bad feeling.

There was some sort of thick substance running down Koneko's legs.

…And it was not pee.

"Yo, Issei!"

"Hm…?" Right as Issei was returning to the karaoke room, Xenovia stopped him in the hallway. "What…?"

"Can you help me out?" She was still licking her mouth without realizing it; There was a dense layer of saliva over her lips.

"Help you out? How?"

"Let me practice my blowjob on you, okay?"

"What?! Whoah!" She grabbed his hand and forcefully pulled him in the direction of the bathroom.

Thankfully, she chose the male bathroom.

Soon, Issei found himself inside a stall with his back to the toilet, while Xenovia squatted to her tiptoes with her back to the stall door.

"Alright, let's do it!" She grabbed his pants and pulled them down-"

"W-wait…! Wait…!" Issei stopped her. "What are you doing, Xenovia?!"

"Practicing my blowjobs! I wasn't able to fully satisfy Marcus' big black cock yesterday, so now I'm feeling a little competitive, you know…?" Xenovia looked and sounded restless. "I wanna suck… Drink cum… S-so I'm better next time I get called! To help Rias, you know?"

"T-to help President…?"

"Yeah, yeah, yeah, so come on, let your dick out! I'm going to make you nut in my mouth to practice!" She pushed him against the toilet seat, forced him to sit, and lowered his pants.

"Ghluuuurgh ! Shluuuuurp ! Shlrrrrrrrrp !" Out of nowhere, Issei started hearing very, very faint sounds of slurping.

Rias' slurping.

'Wh-wha-…?' Sitting on the toilet brought him a few inches closer to the wall separating the male and female bathrooms. That mere distance was enough to allow him to hear the faintest of evidence that his ex-girlfriend was still using her face to eat another man's butthole while fingering herself.

"Shluuuurp ! Ghluuuuurgh Shlrrrrrr-"

"Tch…!" He leaned forward enough to stop hearing it. 'This can't be real…! Get me out of here already…!' He focused his eyes on Xenovia to scream at her to get out of the way.

…But then he stopped, surprised by the look on her face.

"What is this…?" She mumbled.

"What are you- Ah!" Issei had not realized his pants and underwear were down. Xenovia was staring at his penis from so up-close that her breathing rubbed off on it.

"Isn't this too small? Are you sick or something…?" The enthusiasm and agitation she had until a second ago was completely gone, replaced by confusion – and a tinge of disappointment.

"That's because I'm not hard!"

"You're not hard?"

"N-no, I've been having trouble because… Uh… Uhm… What…?" Issei looked at his penis.

He WAS hard.

'Wh-what…? Why…?'

"Shlrrrrrrrp ! Shluuuuuuuuuurp !" By accident, he leaned back just enough to start hearing Rias' degrading rimjob again.

"Oh, it throbbed!" Xenovia exclaimed.

"H-huh?!" Issei leaned forward again and took note of it. 'Wait, I'm hard because I got turned on from hearing Rias doing that?! I can't get hard with Akeno, but I can get hard with THAT?!'

"Let me check…" Xenovia grabbed his dick with her index finger and thumb. "…I don't know… It FEELS hard… But not like Marcus' big black cock. I can crush this easy… If I tried to crush his dick, it'd be a struggle, and I bet I'd lose."

"W-well, that's…"

"I knew he was manlier and hotter than you, but I didn't think the virility advantage was THIS big. This sucks… You barely have balls…"

"So, it's not going to be good practice, right? Let's leave-" He tried to get up but was pushed back down.

"Shlrrrrrrrp ! Shluuuuuuuurp !" Again, his ears found themselves the victim of acknowledging uncomfortable realities taking place in the neighboring bathroom.

"What are you trying to get up for!? You just throbbed again, so you totally want me to blow you. Let me do it!"

"Ghh…!" Issei hunched forward again to avoid hearing the other bathroom. "You just said it sucks because I'm not big like him, didn't you?! Why are we still here?!"

"W-well, uhm… To… To practice drinking semen!"

"Practice DRINKING?! Why does that matter?!"

"Y-yeah… It's not because I want to drink semen or anything like that… I just want to… Uh… Practice chugging it down! Marcus' spunk is super viscous, so it's hard to drink after a while because my throat gets all burned up from the dick scraping. So… Uh… What I'm saying is… Is…"

…

"Shlurrrrrrrp!! Shlrrrrrrrp!!" Xenovia stopped talking and swiftly buried her open mouth onto his crotch, sucking her cheeks in to stimulate his penis.

"Hey!! Nghhhhh! What?! X-Xenovia…! Oooooh…" Before Issei had the chance to react, Xenovia was already swirling her tongue around his length, keeping his full penis lodged into her mouth with ease. 'This is what a deepthroat is like…? Ghnn… She's making it look so easy…'

Xenovia pulled her head back and- "Oh! Sorry…!" By accident, she pulled her head back so far that his penis slipped out of her lips.

Xenovia buried her head in and pulled back- "Shit…! I'm not getting it right…! Sorry!"

Again, she buried her head in and… "Puah! H-hey, this is impossible…! This isn't at all like yesterday! My instinct is to pull my head back and forth way more than this…!"

"I get it, he's bigger! You don't need to keep saying it!" Issei grew increasingly upset with Xenovia's unintended degrading comments.

"Ugh… Fine, I'll keep it to my tongue then… It's just too easy and boring like this…" With visible disappointment, she buried her face again.

This time, she kept it there – in Xenovia's eyes, there was no point in moving her head back and forth because his penis was too small in comparison to what she was used to.

…Which was Marcus' big black cock.

How much had she orally serviced him yesterday?

"Shlrrrrrrp… Shluuuuurp…" Based on her skillful tonguejob, likely a lot.

'D-did she do that to him…? Put it in her mouth and thrust her head back and forth…? W-wouldn't her jaw dislocate? Ah, shit, whatever…! I'm almost there...! I'm going to…! Nghh…!' Because of Xenovia's great oral service, it took less than a minute for Issei to reach orgasm.

As his body trembled from pleasureful release, he lost control and was forced to lean back for the duration of his ejaculation – however brief it was.

Consequently…

"Shluuurp ! Shlrrrrrp ! Ghluuuurgh ! Brhluuuuuurgh ! Shluuuuurp ! Shlrrrrrrp !" …He was forced to endure an enjoyable orgasm while listening to the most hideous sounds he could – Rias eating Marcus' ass.

'Fuck…! Fuck, stop, stop, stoop…!' He kept trying to crunch forward to stop hearing the sounds, but Xenovia's tongue did not ease up. In fact, she seemed oblivious to the fact that he was ejaculating, therefore applying maximum stimulation to get him off.

It was too much for his amateurish penis to handle, making his body jerk in place…

"Shlurp ! Ghlurgh ! Bhrluuurgh ! Shluuurp !" …While hearing Rias for several seconds that felt more like an eternity of humiliation and emotional ache.

Once he was finally in control of his body again, Issei crunched forward and used all his strength to pull Xenovia off his penis by the hair due to the pain of excessive post-orgasm stimulation. "Hah…! Hah…! Hah…! Y-you're killing me, Xenovia…!"

"Hm…? What?" Despite the intensive effort, she did not look even the tiniest bit exhausted or affected by the hair-pulling, as if it was all too easy for her. "Oh, are you already close to release? That's a little fast, but I think it's cool. Because it's small, there isn't much point to sucking for a long time, so we can speed it along, yeah?" She raised a fist as if she had just said something really cool instead of hurtful. "Wanna stroke it out on my tongue? Or want me to suck it off?" Xenovia brought her tongue close to his penis and waited for an answer.

"What are you talking about? I just came!"

"What do you mean?"

"I don't know how I can be clearer than that."

"Uh…" She paused. "You released semen into my mouth? Like, your sperm?"

"Yes!"

"I missed it?! No, that's impossible…! I didn't choke or gag or anything! I didn't even get a little hazy from tasting it!" She started licking her lips fervently. "There's nothing! No cum coating, no salty flavor lingering… Nothing! You can't trick me, Issei."

"I came already! What do you want me to say?! Look! I'm going soft!"

"Going soft…?" Xenovia reacted as if he had said something truly asinine. "I don't… Men go soft after shooting…? Oh! Did you already cum a lot earlier today?"

"N-no, guys go soft after one time!"

"…"

"…"

"So… Only big black cocks attached to muscular guys stay hard after dozens of cumshots…? Guys like you have weaker dicks…?"

Issei had no way of answering without destroying his self-esteem, so he just gritted his teeth and glared in frustrated anger. 'I just orgasmed while listening to Rias licking that guy's ass and now I have to experience this crap?!'

"W-well… Shlurp… Shlrrp… Why don't we try one more time? Shlrp… Shlurp…"

"Huh?"

"Just one more time… Shlrp… Let's try one more time… Shlurp…"

Something was wrong with Xenovia.

It was true that she had been constantly licking her licks as some sort of odd tick…

…But now her lips and cheeks moved as if she was trying to give small blowjobs to the air in-between her words, drooling incessantly.

Not just that, but there was an impatience and instability in her voice that was not present until a moment ago.

"Xenovia… I think you need help-"

"Fuck, Issei, let's just try a different position! How about this?!" She got up, grabbed his shoulders, and switched positions with him in a flash. "I'll sit on the toilet and you fuck my face REALLY hard-"

…

"Huh…?" She stopped talking and leaned back, turning her face slightly to the side.

…To listen better.

Xenovia was hearing the sounds of gurgling and slurping coming from the other bathroom; Issei could no longer hear them due to his new position, but she could.

Her eyes widened and her jaw dropped slightly, drooling. Soon, her nipples hardened significantly, protruding obscenely through her white dress shirt.

"Xenovia…?"

"I need to pee…" She mumbled without looking his way, still focused on the sounds.

"Uh… I'll leave the stall then…"

"No… In the girl's bathroom. This is the boy's bathroom, and I'm a girl… So… I'll just go to the other bathroom real quick…" She got up and walked out of the bathroom.

Issei quickly pulled his pants back up and followed her. "Wait, Xenovia…!"

She stopped right as she was about to open the female bathroom door and looked back at him. "What?"

He was unable to answer, stunned by her mouth.

It was full-on blowing the air as if there was an enormous penis inside her mouth, frantically swirling her tongue.

The sight stunned Issei so much that Xenovia got tired of waiting and entered the bathroom.

Between the door opening and closing, Issei did not see Koneko. 'She was just peeing, so she's probably back in the karaoke room already, right…?'

Issei returned to the karaoke room.

Asia was there.

Kiba was there.

Akeno was there.

…And Koneko was not.

"Issei." Akeno called out to him. "Are you okay?"

"Yeah." He sat beside her.

"Is that so…?" Akeno knew he was not but decided to let him cool down on his own.

"Is something wrong, Issei?!" Asia was the opposite, feeling compelled to help. "Koneko and Xenovia haven't come back yet…! I… I-I think I have an idea of what's happening! I can help! I'll go talk to them right now!" She got up and rushed to the door.

"Wait, Asia, don't…!"

"It's okay, Issei. You saved my life… I'll always do everything I can to help you!" She said in the coolest way she could.

Asia turned the doorknob-

"Kiba." Akeno commanded.

"Yes." Kiba kept Asia from leaving the room. "Sorry, Asia."

"But I want to help…! I want to talk to Rias! Issei is hurting!"

"Asia, pipe down." Akeno said with an unusually serious voice. "Sit down and be a good girl, okay?"

"O-okay…" Her great drive was easily crushed.

"Issei." Akeno turned her focus to him. "Koneko and Xenovia are with them, aren't they?"

"…Yes."

"Do you understand what's happening to them?"

"…Yes."

Issei was not stupid enough to not get it. 'Xenovia drank some of his precum on that first day… And then helped sucked him off yesterday too… The semen is probably affecting her body and mind… And Koneko…'

…

'…I don't know about Koneko… Is it just because he came all over her uniform on that first day…? I thought it had to touch your skin or enter your body, but maybe his semen is so powerful that just the close proximity already affects you… And now they're in that bathroom with Rias…'

Koneko and Xenovia were probably gone, corrupted into desiring more of the Black King's semen. How would their bodies and minds change from now on?

Issei did not want to know, feeling awful about the whole thing. Maybe if he had been more agreeable and befriended Marcus instead of alienating him, he would not have had such an urgent need for release…

…And then, Koneko and Xenovia would not be in that bathroom right now.

Then, Rias would not be passionately rimjobbing him right now.

Then, Issei would not have lost her AND Koneko AND Xenovia.

'Wouldn't Koneko and Xenovia have gotten corrupted anyway…? Maybe not… If President did not have to deal with him because I stressed him out, Koneko and Xenovia would not have the chance to be so close to the act… Maybe with a few nights of normal sleep, they would have been okay. Now, they're in there, doing something… Watching? Masturbating? Or… Joining President? Maybe she will try to push them away and succeed? It's clear that I can't do anything to stop any of it, so… I'll just stay out of the way from now on… The more I try to do anything, the worse it gets.'

"You have to cherish what you have, Issei. A pair of big titties in the hand is worth two around Marcus' big black cock, hm? Well, three, but Koneko's aren't big."

"Yes… I'm sorry, Akeno!" He hugged her, sinking his head into her pillowy chest. "I'm done! I accept it…! Rias can do whatever she wants…! I just don't want to lose you too!"

"Oh, my…!" Akeno blushed from his words. "Now I'm getting emotional too…" She caressed his hair to comfort him.

"M-me too, Issei! I don't want to lose Akeno either!" Asia inserted herself in their hug.

"I think she wants to hear about how you don't want to lose her, Issei."

"I don't want to lose you either, Asia! I'll let Rias go! I'm keeping you both for myself forever!"

"I don't even know what's happening anymore…" Kiba scratched his hair on the other side of the room.

Issei was ultimately forced to accept reality like everyone told him to. It took him far longer than it should have, but he was best off for it.

'I'll cherish Akeno and Asia! I refuse to lose them…!'

"Hey, Issei…" Akeno whispered.

"What…?"

"Let's do something naughty tomorrow." She rubbed his crotch without Asia noticing.

Issei was already hard again.

Letting go was the right choice by a long shot.

"This is crazy, Akeno…!" Issei entered the school gym's equipment room, pulled by the hand by Akeno.

"Since when are YOU so prude?" She closed the door behind them. "Or is your complaint that we should have done it during swimming class…? You prefer one-pieces, is that it…?" She mischievously smiled at him. "I'll make sure to steal Koneko's swimsuit then."

"You stole those clothes from Koneko?!"

"Can't you tell?"

Akeno was wearing a white gym t-shirt that was WILDLY undersized for her curvy figure, struggling to properly cover her expansive chest, bunched up so much that her full midsection was in plain view all the way to where her black bloomers began.

Those were MUCH, MUCH smaller and tighter than they should be. 'I don't understand how she's walking without her bloomers ripping or tearing…!' Akeno's black bloomers barely covered a fifth of her thighs, skin-tight to the point that her slit bulged out of it in a thick cameltoe; Her asscheeks were equally highlighted, with the fabric burying itself so deep into her asscrack that her butthole was outlined almost perfectly.

She appeared at random in the middle of their PE class, pulled him by the hand in front of everyone, and dragged him to the equipment room.

"Th-they all saw us come in here!"

"Oh? So it's a problem if everyone thinks you're railing me in the equipment room while they're sweating their butts off in that boring class? Or is it a problem that they all got to stare at this…?" She spun in place, going out of her way to push the limits of her bloomer's elasticity against her thick rear. "Or is it because they all got to stare at these a little bit…?" She cupped her breasts and moved them up and down to tease him – her nipples protruded against the shirt.

"I… Uh… I don't know…" Issei felt himself growing hard; It was difficult to remember what he was saying. "Heh… Heh heh heh heh…" A smile instinctively formed on his face, mesmerized by Akeno's curvaceous figure struggling against her clothes.

"I guess you're not a prude in the first place, hm…?" She squeezed her large breasts against his chest and whispered in his ear. "How about you wreck me, then…? No one's going to find us… You deserve to get a nice, sexy fuck after the past couple of days, don't you…?"

"I do… I totally do… He he he he…" His brain function was degraded after too much visual stimulation.

"I love it when you turn into a horny perv." She kissed his lips and grabbed his crotch through his pants. "Oh, you're nice and hard. I've been missing this strong erection in bed at night… Then, right here…" Akeno bent over against the nearest vaulting box. "…Take me from behind. Mark this box as yours by fucking my pussy hard and painting it with the smell of our sex. The next time some girl jumps over it, she'll smell your cream."

"Alright! Let's do it!" Issei lowered his- "Huh?"

"Oh?"

They were interrupted by the sound of the door opening.

"Let's hide over there!" Akeno pulled Issei by the wrist, leading him into a nearby locker with her.

"This is the worst luck…!"

"Oh, my! Is it…?" Inside the limited space provided by the locker, Akeno's sideboobs inevitably pressed against him. At the same time, she rubbed his bulge with the back of her hand. "I think it's hot… While some naive teacher is coming in to do something, you're getting a nice tug from your big-titty girlfriend. Doesn't that sound good?"

"Heh… Heh heh heh heh… Okay, maybe it isn't bad luck…" It did not take much stimulation to turn Issei into a perv. Akeno always knew what buttons to push.

Akeno inserted her hand into his pants and started slowly and gently stroking him.

For a moment, Issei thought they would have a genuinely naughty, enjoyable experience.

And then he saw Rias into the room, pulling the massive Marcus by the hand. "We can do it here."

"Oh, my…" Akeno was as surprised as Issei. "This is a poor coincidence, isn't it…?" She stopped stroking him.

"Rias…" Issei whispered under his breath.

Rias was wearing the same outfit as Akeno, except hers was not undersized. Even then, her huge breasts pushed the shirt up so much that there was still a small gap between it and her bloomers, leaving a bit of her midsection exposed; Similarly, her correctly-sized bloomers also provided a clear outline of her bubble ass.

Both Rias and Akeno were more than meaty enough to make any clothing skin-tight; Akeno had just gone out of her way to make hers indecently so by stealing Koneko's uniform.

"Are you sure about this, Master…? I-I don't know if it's a good idea…" Marcus was reluctant.

"No. It's fine. This was always going to happen. It's my fault that you're in this state even after so many releases…" Rias sounded more tired and drained than ever. The bags under her eyes were huge, implying an intense lack of sleep.

"I-it's MY fault, Master! It's my fault for having this body…! It's my fault for not being able to control myself! I'm a monster, and you're just helping me! You can't feel bad!" The man was about ready to cry again.

Rias stood on her tiptoes and caressed his face. "Marcus. You understand what we're going to do, don't you?"

"Sex…"

"No. You're wrong." Rias turned around and approached a nearby vaulting box; Ironically, the same one Issei and Akeno nearly used.

"I am…?"

"Not sex. Hardcore breeding sex." She bent over, supported herself against the vaulting box on her elbows, and kept her feet close together to perk her ass up for him. "You will breed me hard until you are fully satisfied. Nothing else will satiate your curse."

"M-Master…!"

Rias looked back at Marcus. "Everything else we've done is a waste of time. Honestly… I've known from the beginning that there was no way to calm you down other than prolonged, harsh sex with direct release of semen deep in my womb, but I thought it was worth a shot since so little is known about the Black King piece…" She paused. "No, I'm lying. I was holding back because…" She looked at the floor with sadness in her eyes. "…It doesn't matter why. Pull your big black cock out."

"Are you sure-"

"I am sure. Pull your big black cock out, Marcus. This is a direct order from your Master."

Her words carried tremendous authority, making him lower his pants in a comical rush.

The moment his penis was fully freed from the tight constraint of his pants, his enormous black cock shot up at full speed smacking his abs multiple times. Then, due to its sheer weight, it fell on top of Rias' back, making her body almost topple onto the vaulting box because of the force and weight.

Its girth and length covered an indecent amount of her body; If not for her bloomers, its shaft would have likely sunk into her asscrack with ease while the tip reached all the way to her middle back.

Issei already knew that it was huge from seeing it multiple times, but observing it resting against her body was a whole new experience, making his heart pound in horror. "That… Can't possibly…"

"It'll fit." Akeno said.

"Huh?"

"It'll fit. Big or not, Rias will take it as part of her duty."

"…" Issei believed her. The past couple of days had crushed his spirit too much.

"Go ahead, Marcus." Rias said with determination in her voice and eyes. "Tear my bloomers off… Go as hard on me as you want."

"But… You don't really want to do this… Do you? Because of me, you're not with Issei anymore… You're not happy…"

For a brief second, Issei's mood perked up.

"That's not right, Marcus. I… I'm actually very excited." …Only for it to crash down again.

Rias had a very nervous smile on her face. If Issei wanted, he could use that as a way to think that she was lying to make Marcus feel better.

However, Issei had seen her in the stall with Marcus yesterday. 'She masturbated and came while licking his ass… She might be nervous, but… I bet she really is excited…' He truly had accepted reality. 'She doesn't love him, but she likes it on a physical level… His body is just that great compared to mine…'

"If you're excited, then why do you sound so afraid, Master?!" Marcus was also aware of Rias' nervousness.

"Because I'm scared that if I let you really go at me, you'll steal my heart."

…

'What…?' Issei went pale.

"Your big black cock… It's so… So… Attractive… !" Her tongue dangled out, panting slightly. "It's so heavy…! I feel it pushing my back down, throbbing to knock me up with your potent semen…! Every time I see it… Touch it… Suck it… I get excited about what it might feel like to have it inside my uterus, releasing that deliciously thick sperm directly inside me …"

"M-Master…"

"You made cum a bunch of times without even putting it inside me. I came with you far more times than with Issei, and I love him! That's why I'm scared… Because I thought that if I let you fuck me with the intensity necessary to satiate your curse, you would sway my heart and mind on pleasure alone. I love Issei… So it's difficult for me to admit how much I want to be fucked by you, even past my duty as your master. Your body is so attractive and your cock is so powerful that it could make me forget him…"

"I didn't know you felt that way…"

"That's because you're a good guy, Marcus. I'm the bad person for ruining your life with the Black King piece. So, from now on, please don't blame yourself anymore, alright…?" She raised her upper body – despite the heavy cock weighing on it – and twisted herself to kiss him while bringing a hand to his nape for support.

…It was the most erotic kiss Issei had ever seen come from Rias.

Their tongues dangled out of their mouths, rubbing and intertwining together as spit dripped down, falling on her bloomers, staining them.

"Mnhhhm … This is the first time we kiss, isn't it…?"

"Y-yeah…"

"Could you feel my excitement?"

"Yes…"

"Then, promise me you won't hold back anymore. You have an amazing body and penis that are capable of pleasing women with intense sex unlike any other person on this planet. You used to be skinny, and now you're strong and manly. Your new body is so incredible that I want to be fucked a lot by you even while I love another man. So, embrace your absurd masculinity and destroy me, okay? I want to feel really good with you, and I want you to feel really good with me."

"But… What about your heart… And Issei…? And you could get pregnant…"

"That's my responsibility, not yours. Your responsibility is to use me like a whore to pump your cum into. As for my heart… I won't lose my love for Issei. But I might fall in love with you. Would that be so bad from your perspective? You have a thing for me, don't you…? Didn't you use to like all the cosplays I did for you back in the day? I could see you staring at my boobs."

"W-well…"

"Marcus."

"Y-yes?"

"My body is yours now. Knock me up ." Rias bent over again, gritted her teeth, and waited.

There was still a nervous smile on her face.

…But even more excitement.

…

"Master! I've also been hiding something!"

"Is it a fear that if you stop holding back and decide to enjoy the feeling of using my body, you might not be able to stop until I'm broken?"

"H-how did you know?!"

Rias giggled. "You're so easy to read. Let it all out. Show me what it's like to be fucked by a Black King's big black cock."

"Fine…! I'll… I'll fuck you hard!" Marcus tore off her bloomers and shirt, removed his own clothes, grabbed his penis, and directly poked her slit with it. "I won't hold back!"

"Good."

"I'll really do it!"

"Excellent."

"I'll… I'll treat you… Like a worthless sex toy, Master…! Like a fleshlight. I'll knock you up!"

"That's exactly what I want."

"Fine…! Fine…!" Despite his words, his face was covered in nervousness, with tears nearly coming out of his eyes; Marcus even hyperventilated a little.

…But his resolve was irrefutable. He wanted to change and move past his insecurities.

"They're going to fuck." Akeno finally broke the silence between her and Issei with a whisper. "Issei. I suppose this change of events makes it a little awkward for you, doesn't it…?"

Issei nodded nervously.

"I empathize with your feelings…" She brought her lips to his ear. "…But I miss having fun with you, so I'm not going to stop."

"A-Akeno?! Ghn…!" His body flinched upon feeling her grip tighten up around his penis.

Akeno had been made to wait for too long. The past two days of Issei ignoring her to obsess over Rias had hurt her more than he realized.

She wanted him NOW, even if it was while watching Rias and Marcus doing something.

…

That was a good thing.

Akeno DEEPLY desired Issei.

And so… "I don't mind! You can jerk me off, Akeno." …He decided to match her expectations.

"Oh, my …" She loved his response, moving her hand with fervor.

Issei truly meant his promise at the karaoke room yesterday. Even if it still hurt, he had let go of Rias, accepting that she intended to do her duty at all costs. 'I'm not losing Akeno or Asia! Or Xenovia and Koneko if something can still be done! I'll cherish what I have before I lose even more! I… I don't care even if President gets knocked up…!'

"Jerking you off while we watch Rias get bred by Marcus… I'm a little excited." A naughty smirk formed on Akeno's face; Dirty as she was, she was able to find plenty of reason for arousal in the present situation.

Issei was different. He was uncomfortable but would power through for the sake of their relationship. 'It is what it is…! They're going to do it…!'

Marcus gritted his teeth…

"Nghh …" Rias gritted her teeth…

Issei gritted his teeth…

And Akeno jerked him with tight, slow strokes.

And then…

"MNGHHHHHHHHHHHHHHH!!!" …Rias was penetrated by a big black cock for the first time in her life. "Khhhh…! Ghhnnn...! Mnghhhh…!" Even though Marcus made no more motions after the initial penetration, Rias' face contorted excruciatingly, clenching her teeth to avoid letting out shrieks of what must have been deep pain. "Ghh…! Khhh…!"

"Master…! Khh…! It's…! Tight…! Really tight…! And I still…! Have a lot…! To push in…!"

"Ghh…! Hah…! Nghh…! Mnghh…! Hah…!" Rias clearly wanted to say something but was unable to; Her entire body was contracting so hard that she was not able to breathe, with her face quickly turning an intense shade of red. "Mnghh…! Ghhh…!"

"I can't move…! Without forcing it…!'

"Khhh…! Ghhhh…!"

"Should I…?!"

"Nghhh…! Ghhh…!" Veins popped all over Rias' face, with her neck muscles tensing up far beyond what was healthy, showcasing her efforts to breathe and speak.

"What should I do, Master?!"

"Mar-… Cus… Ghhh…"

"Yes?! Yes, Master?"

"…I'm… Ghh… Just a… Khh… Fleshlight."

…

"I understand… Khh… Master…" Marcus' eyes were filled with determination. He understood her sentiment.

Rias was fully offering herself as part of her duty.

It was onto Marcus to…

"MNGHHHHHHHHH!" …Take her. "GHNNNNNNMMMM!" He leaned forward and supported his fists on the vault box too, towering over Rias; It truly looked like she was mounted by a gargantuan dark breast because of his height and build. With that leverage, he pulled out with reckless force, fully disregarding the grunt of pain splurging between Rias' clenched teeth.

…Exactly as she wanted. "GHHNNNNN! MNHHHHHH!" Even if amateurishly, Rias understood her role as the weaker one in their sexual relationship. Her purpose was only to take it. It was on Marcus to use her until satisfied.

Marcus successfully pulled his penis out all the way to the tip. The upper third – which corresponded to the length he managed to brutally insert in Rias' tight, inexperienced vagina – was glistening in pussy juices, with veins bulging so much that they almost looked on the verge of bursting.

"Oh, my. Rias is quite wet, isn't she…? He'll really impregnate her…" Akeno whispered, still proficiently moving her hand inside Issei's pants.

"Don't say that… I don't want to hear it…"

"My bad… It's just that between seeing her face, his shirtless muscles, and his big black cock inserting into her, I couldn't help but comment…"

There was something weird in Akeno's tone, but Issei did not bother paying attention, too distracted by the horrible sight in front of him, even if partially compensated by Akeno's pleasurable strokes.

"Get ready, Master…! Grrr…!" Marcus flexed his abs, clenched his fists to the point of filling his forearms with veins, and…

"NGHHH! MNGHHH! GHNNN! UUUUUNGH! OOOOOOOH!" …Began using Rias like a fleshlight, thrusting back and forth at a maniacal pace.

"Ghh! Khh! Ughh!" Each thrust was accompanied by loud, deep, masculine grunts. It took only seconds for the entirety of Marcus' body to become clad in dense veins, with sweat coating every inch of his dark skin.

Rias did not get as veiny as quickly, but she did get far, far sweatier.

"UUUNGH! GHNNN! MNGHHH!" Enduring the aggressive assault of a massive cock by a massive man was no easy feat. Her contorted face from a few seconds ago was a joke compared to the face of agony she was making now, unable to keep her eyes in place.

"OOOOOOH! NGHHHHUUUUGH! GHNNNNNNN!" Her entire body trembled nonstop. There was a high likelihood that if Marcus stopped thrusting, she would simply collapse. In a way, his large girth going in and out acted to keep her impaled in place, even if unsteadily.

"HOOOOOOOH! GHNNNNN! MNGHUUUUUGH!" Her ample, heavy breasts swung back and forth due to the ruthless cock hammering. With each piston, her feet threatened to leave the floor. Rias was standing on the very edge of her toes to keep up with his fervent pace.

"It's tight…! Master, you're really tight…! You're squeezing me…! But I won't let up…! I won't slow down…!"

"NGHUUUUUUH! GHNNNNNNN! MNGHHHHHHH!"

"I'll keep my promise…! And not hold back…! I'm not slowing down…! Until I bottom out…!"

"UUUUUUUNGH! MNGHHHHHH! NGHUUUUUUGH!"

"You're just…! A little whore…! Right now…! So I don't care if you lose it…!"

It was a murder.

Issei lacked other words to describe what he was seeing, stunned by the savagery of the sex act. The woman he loved was being thoroughly sexually obliterated by Marcus.

It was horrifying and scary to think that sex of such harshness could exist. Issei had always seen sex as a moment of intimacy and naughtiness. The sex before him was anything but. 'That's the sort of stimulation this guy needs to feel satisfied? Rias has to get used to this…?'

"…It's… Quite exciting, isn't it…?" …Akeno randomly whispered the creepiest thing she had ever said to Issei.

"Wh-what…?"

"It's quite exciting… Look at how he's fucking her… I must admit that I didn't realize it was THIS rough and hardcore… Breeding sex with a big black cock is even crazier than I anticipated." Her breathing was slightly ragged.

"Akeno… Are you okay…?"

"I'm fine. I just… Couldn't help but note."

"R-right…"

"HYAH!" Rias wailed as her back arched in an abrupt spasm, capturing Issei's attention again. Marcus had violently descended his hand against her thick butt, sending ripples across her body and indenting her rear.

"Did it hurt, Master?! No, wait…! I don't care! I want to slap your ass, so I'll do it! I'm assuming ownership of you…!"

"HYAH! NGHH! UUNGH! HOOOH!" Rias shrieked and spasmed again and again as repeated slaps were dished out to her ass. It did not take long for part of her skin to turn red from the harsh impacts, all while Marcus continued to slam into her, keeping her body in a permanent state of shaking and grunting.

"Khhh! Even though you're so wet…! You squeeze so much…! I'll pry you open, Master…! I'll keep my promise…! I'll bottom out and empty my balls inside you…!"

"UUUUUNGH! MNGHHH! NGHHHHH HYAAH!" Rias did not seem to follow a single word he said, far too immersed in the pain of having her body brutally hollowed out with merciless thrusting.

For the longest time, they kept going like that.

Marcus kept ramming and slapping her ass…

"GHNNNN! MNGHHHH! UUUUUUNGH!" …And Rias kept grunting and wailing in pain while her breasts danced back and forth due to the inevitable inertia caused by being pummeled so violently.

Even in the wildest pornos Issei had watched throughout his life, he had never seen a woman be taken from behind with so much ferocity.

That said, he had never seen a video involving a woman being taken by a 6'5' brute covered head to toe in veiny, bulging muscles and carrying a colossal, veiny black cock.

'Is he going to fuck her this hard every day?!'

Sona had told him that whatever he imagined, reality was worse.

So, Issei was afraid of imagining the future.

…But was still unable to look away from the reality in the present.

"NGHHHH! GHHHN! MNGHHHHH!" No matter how much time passed, Rias continued to have trouble breathing due to her body bracing excessively to handle the pitiless pounding. She was starting to lose her footing from endless trembling. Though Rias was not particularly muscular, her leg muscles popped out more and more due to the isometric contraction involved in remaining on her tiptoes to take Marcus' fucking.

"It's just a matter of time until her body gives out…" Akeno said in a slightly breathless voice.

"H-hm…?"

"He's REALLY taking her… I don't think she can speak even if she wants to. But still… She must be feeling tons of pleasure…'

"P-pleasure…?"

"Yeah… Don't you think so…? I mean, he's fucking her a little inhumanely, but…" She turned to face Issei directly; Her tongue dangled slightly out of her mouth, breathing heavily. "…It's a really juicy big black cock, isn't it…?"

"A-Akeno, you're looking a little-"

"Oh, my. I've been neglecting you, haven't I? Let me speed that up."

"Ghhn!" Issei crunched from the sudden increase in jerking speed. "W-wait, Akeno…!"

"Shh… Let's watch, let's watch…" Akeno completely ignored him to focus her eyes on the action some more – but still stroking him. "Look…! It's getting even crazier! So manly…!"

"E-even crazier?!" Issei also looked.

"NGHHHH! UUUUNGH! MNGHHHHHH!" Something had changed: Rias' feet were no longer touching the floor whatsoever. Marcus' savagery had ramped up to the point that his enormous penis impaled her lower body into hanging solely on it.

"Ghh! Khh! This angle is bad…! Come over here…!" Marcus grabbed Rias' hair and pulled it until she was fully lifted in the air, with her back hugging his muscular front. Then, he brought his arms under her kneepits and locked her feet beside her head with his hands locked behind her head: Rias was taken in a restrictive Nelson Hold that demanded excessive flexibility from her in a moment of great physical stress.

"NGHHHHH… UUUUUUUNGH…" She drooled between clenched teeth; The present position was far, far more demanding of her body than the previous one, forcing far too much of her body weight to rest directly against the gigantic penis impaled inside.

The new angle allowed Issei to get a better view of how penetrated she was. 'H-he's got half his dick into her…! That's so much…! How can it fit?!'

"Wow… Her vaginal lips are so stretched to the sides…! Look how they're twitching…" Akeno panted. "It's gotta be pushing up against her cervix…"

"H-her cervix?! Khh… I-isn't that supposed to hurt? Ghh…"

"Issei."

"H-huh?"

"Finger me ."

"Huh?!"

"Finger me…! Come on…!"

"O-okay!" Issei moved a hand into Akeno's bloomers and inserted a finger into her vagina to stimulate her.

Why was she so, so wet? 'I don't think I've ever seen Akeno this aroused! Is she into voyeurism?!'

"Issei…!"

"What?"

"More fingers! Come on…!"

"Okay?!" It was the first time Akeno desired more than one finger from him; Yet another sign that voyeurism might be a fetish of hers. Issei inserted two more fingers.

"That's better … Ah, look…! Her cervix is about to go…!"

"What?!" Issei looked again.

"OOOH! HOOH! NGHOOH! UNGH! MNGH! GHHN!" Rias howled maniacally as her pussy was violently mauled by Marcus in the restrictive hold. Every single motion was deep and fast, pulled out to the tip before hammering back in at full force. Each time, his balls swung enough to graze her clit. If he managed to get a few inches deeper inside her, there was no doubt that his balls would CRUSH her clit again and again.

And that was going to happen anytime soon.

One would have to be clinically insane to reach a different conclusion after witnessing the strength with which Marcus was slamming into her. If any doubt was left, one simply had to observe the increasing lack of sanity on Rias' face, or the increasing intensity with which Marcus' teeth clenched in pleasure and physical exertion.

Or his huge legs;

Or his huge muscles;

Or her sweaty, red upper chest;

Or her swinging breasts;

Or the absurdly huge bulge moving up and down her flat stomach.

…

'What…?' Issei blinked again and again to make sure.

There was a massive cock bulge moving up and down her flat stomach.

It had happened so fast.

From his perspective, there was no protrusion on her stomach… Until there suddenly was.

Should it not have been noisier? Was there not a cracking sound missing? It felt so sudden!

Naturally, it only felt so because Issei was a moron.

For Rias, the one receiving the full power of Marcus' deranged thrusting, it was certainly not sudden. Her cervix had been getting rammed by his hard, thick glans for a long time now. She probably felt it slowly and slowly crumble with each hit, sending jolts of pain to her brain that made it impossible to think or remain sane.

Nevertheless, the lack of a guttural, desperate groan by Rias caught him off-guard.

Once he looked at her face again, it made sense: Rias could not make sounds, though she desperately tried to. Her neck was at its peak tension. All sounds were obstructed despite the presence of direct pressure on her windpipe.

And yet, her face told everything. Rolled-up eyes, a dangling tongue, intense blushing, and a head tilt that made her living status questionable.

"……………….." Rias was enduring insufferable silent pain-

"She's cumming so hard … W-wow …" Akeno mumbled.

"Cumming?! Sh-she's in so much pain-"

"Faster, Issei… ! Don't stop fingering… !" She cared little about what he had to say, rocking her hips slightly to make his unskillful fingering even more stimulating.

For a while now, Akeno had stopped stroking, not even pushing him to completion.

Her heavy breathing, distraction, and increasing lubrication worried Issei, yes…

…But he was curious about Akeno's assertion, leading him to ignore that worry in favor of proving her wrong; All he needed was to look at Rias again and confirm things in his brain.

Rias was in pain.

…Is what he wanted to internally reassert until he was forced to perceive a different reality.

An uncomfortable reality.

A reality in which Rias was convulsing and squirting like a madwoman. Her juices flew so far that they nearly hit their locker. Her pussy, which had been twitching maniacally so far, somehow found the ability to quake even more, gushing fluids that ran down Marcus' substantial scrotum. The only reason her head did not throw itself back in the convulsive orgasm was that Marcus kept both his hands behind it, pushing it down.

It was an unbelievable sight for Issei, filling him with indescribable ache. Seeing Rias feel pleasure several magnitudes greater than she ever did with him was destructive to his ego.

Still… Something was missing.

Was it truly possible for a woman to cum and squirt so hard without a single moan…?

Again, he examined her face.

That was when Issei realized it was just a matter of time. He could feel the big wail welling up inside her, fighting to break out.

As if time had slowed down, he saw her mouth open up wide, her tongue shoot out even more, and then…

"NGHOOOOOOOOOOOOOOOOoooooooOOOOOOOOoooooooooooooooooOOOOOOOOOOOOOOOOooooooooonghhhhhhhuuuuUUUUUUUUuuuuuuuuu !!!!" …The grand echoes of pleasure filled the room.

And after that first one…

"OOOOOOOOOH ! NGHOOOOOOH ! HOOOOOOOH ! UUUUUUUNGH ! MNGHOOOOOOOH ! GHNNNNNNNNNNN !" …There was no more stopping. Submissive howls flooded out of Rias' mouth as if a dam had been broken through. Her body quaked madly as her abdomen contracted around the enormous black cock packed deep into her womb, shoved in to the point that his shaft was fully hilted inside her.

Issei thought the sex could not get more brutal and absurd than that.

That conclusion was only reached because he had not accounted for the fact that Marcus had not been thrusting whatsoever after breaking into Rias' womb, stuck in place due to her uterus clamping down so hard.

Once he saw Marcus' penis pulling out to slam in again, his expectation adjusted accordingly.

There was much, much more room for the sex to get more brutal and absurd.

"NGHUUUUUUUUH !!! OOOOOOOOOOOH !!! HOOOOOOOOH !!!" How else to describe the squirt flurries that came after that?

"MNGHUUUUUUH !!! HOOOOOOOOOH !!! GHNNNNNNN !!!" Rias' body entered an infinite state of psychotic convulsion, shaking frenziedly as Marcus SLAMMED his full length in and out of her, not slowing down whatsoever even as her insides clenched desperately amidst squirting orgasm after squirting orgasm.

"OOOOOOOOOH !!! NGHOOOOOOOH !!! UUUUUUUUUNGH !!!" Now that his full monster cock could make its way inside her by rearranging her womb to become a bag to squeeze and milk his glans, his low-hanging heavy balls were finally able to swing enough to smash her swollen, sensitive clit.

Every.

Single.

Time.

"NGHHUUUUUUUUUUUUUUUUH !!!!!!!" Rias was done for.

Not in terms of physical stamina; In that regard, she had been done for a while.

Rather, she was done as a woman. Issei simply knew that on an instinctive level. The way her body had been taken would never be forgotten. As silly as it was, he would fully believe if told that her vagina would never close up again. The girth stuffed into it was too large.

"She's… Blacked for life… Aaah …" Akeno again muttered weird things.

"B-blacked…?"

"You don't know what that is, Issei? A porn-watching perv like you? Hah … Don't stop moving your fingeeers… !"

"S-sorry!" He sped up his fingering again; Akeno was so wet that it produced light squelching. "I-I do know what it is, but how do YOU know?"

"Maybe I'm a bit of a perv too… Hah … Nghh … Oh, shit…! Oh, no way…! It's happening! He's going to release inside her…!"

Issei's attention shot back to Rias and Marcus.

"GHHHHHH! KHHHHHHH!! GRRRRRRRR!!!" Marcus had begun grunting even more furiously, with his legs trembling insanely while maintaining a cruel rhythm of slamming.

The great moment did not become evident from a big change in Marcus' body language. Instead, it became evident due to a bizarre visual change in Rias herself.

"NHGOOOOOOOOOOH !!! HOOOOOOOOOOOH !!!" Namely, the emergence of a growing belly where her flat stomach was supposed to be.

Marcus was releasing such a voluminous load so deep inside Rias – directly against the back of her womb – that it welled up into a small cum belly. 'I am watching… Rias get impregnated in real-time…? Right now… Right now, exactly…'

If asked beforehand, Issei would have guessed such a thing to be painful from Rias' perspective.

Now seeing reality, he knew it was not painful.

Or, at least, if it was…

"CUMMING ! CUMMIIIIIING ! HOOOOOOOOOOOH NGHOOOOOOOOOH !!!" …It was not more painful than the sexual ecstasy that came along. The pleasure was seemingly so strong that Rias uttered her first words ever since the massacre had begun.

They were not elegant words, but they had weight: There was an immediate and sharp increase in the density and frenzy of pussy juice squirting out of her body. Apparently, there was still room for her to cum harder.

Slowly, amidst brutal thrusting, her small cum belly grew a little more…

Slowly, her medium cum belly grew a little more…

Slowly, her large cum belly grew a little more…

All of a sudden, Rias had become a woman with a belly so expanded that she looked significantly pregnant.

Three months?

Four months?

Five months?

It was hard to estimate because the cum pool inside her womb would not stop swirling around.

…There was a gigantic black cock violently coming in and out, after all.

Marcus' length was so thick that it was a miracle that any volume of semen managed to leak out of her plugged hole; A consequence of him pulling out all the way to the tip each time to ensure maximum stimulation and gouging, re-running through the entire distance of her sensitive inner walls with every thrust.

Issei could not belie-

"Issei, you're screwing up at the best moment…!" Akeno cut off his inner observations by slapping his hand away from her bloomers.

"Wh-what?"

"Shit, shit, come on…!" Akeno inserted her own hand inside her bloomers and started masturbating by herself.

Furiously so.

MAULING her pussy with aggressive fingering. The squelching from Issei's fingering was a joke compared to the sounds made now; Akeno was going much harder on herself than Issei was.

At the same time, she was gritting her teeth while watching Marcus and Rias with wide eyes, not blinking at all.

Soon, her legs started shaking like crazy and…

"Mnghh … Nghmm …" …Soft groans escaped from the bit lips of her cross-eyed face.

Akeno was orgasming hard from masturbating to the same act that Issei was horrified by.

…

'…Is the Black King curse affecting her just from watching…?'

Was he losing Akeno in real time without realizing it?

'I… Don't know…' He returned his eyes to Marcus and Rias.

"Hah…! Hah…! Hah…!" Marcus had finally finished ejaculating inside her. Overall, he released more volume in a single orgasm than Issei could release throughout an entire month. Even though Marcus had remarkable stamina, he looked spent.

At first, it made no sense to Issei. As far as he understood, Marcus had been releasing load after load for the past couple of days. Should one ejaculation have really drained him so much?

Then, he remembered everything he had learned so far. 'Hardcore breeding sex… That has a different impact, is that it? Because he came inside her, it satisfies him more…? Rias is probably pregnant now… Does that finally satisfy him?!'

Regardless, little changed in terms of the rigidness of his erection. His massive black cock remained lodged deep inside Rias, pulsating at random; Each pulsation was accompanied by the cum pool inside swirling at the same time. Because his penis was shoved all the way in – or so Issei thought, since the large belly camouflaged the cock bulge that existed a while ago – no semen leaked out; The plug was simply too snug.

As for Rias…

"……………………………………………………" …There were no signs of consciousness. One of her eyes was almost fully closed, twitching; The other was mostly rolled up, also twitching. Her mouth was slightly open, and her tongue dangled slightly out. Finally, her head tilted to the side due to its weight, with her neck forgetting to keep it straight from raw exhaustion. Her overall figure was soaked in sweat, and her vaginal lips and clitoris were as puffy and swollen as they could possibly be without it looking medically dangerous.

Every few seconds, she let out small gushes of pussy juice, unprompted. Though her body shook, she made no sounds, nor did she move her face in any way, shape, or form. Every muscle on her body was tense, contracted to the limit, and her face was red. That said, her chest WAS heaving up and down, so she WAS breathing… Even if with questionable effectiveness.

Rias was done for; Somehow, more than before.

'Sh-should I do something…?' He looked toward Akeno for some form of emotional support.

"Ghnn … Nghh …" Akeno was still savaging herself in aggressive masturbation.

…So, Issei simply watched on.

Marcus and Rias remained still in the same sex position for a long time.

Him basking…

…And her existing.

Eventually, he gently put her down on the vaulting box, facing up.

"M-Master, are you okay?!" Only now did he realize that Rias was not conscious. "Master?!"

"Ugh ……… Ghn ………" She let out quiet groans, breathing raggedly as cum finally began pumping out of her body now that her vaginal cavity was unobstructed. It was like a waterfall of semen. It took mere seconds for Marcus' feet to change colors, covered in the texture of his own sperm. "Nghh !"

"Master?! Wh-whoah!" Marcus raised his hands to cover his face as a random bout of pussy juice fired out of Rias' pussy. Now that the sperm was leaking out, she started cumming again.

There was no way around it. She needed a break.

"Incredible … He destroyed her to that point … I didn't know it was possible to be fucked to that degree … Sex with a big black cock is… Special … She's knocked up for sure…!"

"A-Akeno…?"

"Issei… I think Rias came so much… Isn't it crazy… ?"

"Uh… Th-that's…"

"But it's hard for her … Her body doesn't develop because she's a High Devil … So she doesn't receive the changes and growth she needs to handle an assault of that magnitude … If it was me, I'd be able to take him. Not at first, but eventually, and much better than her …"

"Akeno…?!"

"Hm? Oh, sorry… I guess I'm saying weird things. I'm just pitying Rias is all."

"That's all…?"

"That's all …" She said, pulling her hand out of her pants.

There was not a single inch of its skin that was not soggy with excessive female lubrication.

"You like looking at it…?" She noted his eyes on her hand.

"Uh- Mnghh?!" Issei could not respond before Akeno shoved her fingers into his mouth.

"You should taste them, Issei. They were produced with the strongest orgasm I had with you yet. Isn't that nice…? I hope it's thick and flavorful…"

Akeno had always been the type to tease and dominate, but there was something odd this one time; A hint of malice that Issei had never sensed before.

Intimidated, he licked her fingers as she asked.

All of them.

Fully clean.

"Oh, my… If I'd known you were this good at finger-sucking, I'd have told you to suck my fingers so many times before…"

"A-awesome… Hahah…"

"Master!" Marcus' shout called their attention. "I'm sorry for what I'm about to do…! But I promised to use you like a fleshlight until I was empty, and I still have a lot more to go…!"

He supported his fists on the vaulting box to shove his cock yet again into her.

…

"What?! Sh-she clearly can't keep going…?! We have to do something, Akeno!"

"It is what it is, Issei. Black Kings and their big black cocks… They're powerful and unrelenting."

"B-but she… She can't take it anymore…!"

"Can't she? Well, either way… I bet she's going to cum lots, so I'm a little jealous ."

"Jealous…?"

"Oh, my. Don't pay attention to me, I'm just teasing you. We should go, shouldn't we? There's only so much I can watch before I start feeling like a cuckold…"

"You're going to portal us out of here? And leave her?"

"She's the one who wanted to hog that wonderful cock all to herself. Now it's on her." Akeno touched Issei's shoulder to portal them out of there.

…

…

…

"Akeno…?"

"Hang on …" She moved a hand back into her pants and rubbed her slit once more.

They both watched silently until…

"NGHUUUUUUUUUUUUUUH !!!" Rias was penetrated again, letting out an involuntary wail even in her unconscious state.

"Ah… Wonderful… Nghh… !"

Akeno portaled them out.

"Issei. It's midnight. Why are you calling me this late?" Sona was moody on the other side of the phone.

"I'm sorry, but I needed to talk to someone!" Issei was hidden in the bathroom of their mansion.

"I see. It was a great talk, have a good night-"

"Waaaaaaait! Seriously, hear me out!"

Sona sighed. "What?"

"I-I wanted to ask about the Black King curse!"

"What about it?"

"S-so, it affects women by… Uh…"

"Direct contact or ingestion of the semen."

"Wh-what about… Uh… Smelling or looking at him having sex or anything like that…?

"

"Are you asking if that can also corrupt and warp women?"

"Yes!"

"No, it can't."

"Huh?" Issei was surprised by her answer, expecting to hear something closer to 'maybe' or 'I don't know'. "Didn't you say not much is known about the Black King curse?!"

"Yes, but not in that sense. I meant that we don't know if he needs to impregnate women to reach satisfaction or if the simple act of raw sex works. Also, not much is known about how it alters the bodies of women. Some grow more, others less… It's hard to determine a pattern. Also, it probably affects High Devils at least a little too, but we don't know how much. In terms of how it starts affecting women, though, it's only via direct contact or ingestion."

"Are you sure about that?!"

"Yes."

"Are you really, really sure?!"

"…Yes."

"But-"

"Issei. What is this about?"

"I… Uhm…" He paused. "…I'm worried that… Akeno might be getting affected… She didn't drink or touch anything, but… She saw him and Rias…"

"…And what? Saw the appeal? Didn't we talk about this? Even without any curse, Marcus is tall, muscular, hung, and masculine. He could fuck any girl he wanted, Black King piece or not. She's just feeling the normal attraction of a woman."

"That can't be it! Akeno isn't like that…! Rias isn't either! They don't care about looks or shallow things like that… Personality is everything to them!"

"Issei." Her tone got stern.

"Y-yes?"

"EVERY woman likes tall; Muscular; And hung. Wake up. I've masturbated multiple times a day since Marcus returned, fantasizing about him fucking the shit out of me, and I've barely interacted with him."

"B-but… But…"

"Relax, alright? If Akeno did not touch his semen, she's the same woman she's always been, for better or worse. Now, I need to go. I'm busy with something-"

"Please, Master…! You're stepping too hard…!" Saji whimpered on the other side of the phone.

"Shut up, dog! Lick-"

The call ended.

…

Initially, Issei felt demoralized. 'She's saying that Akeno is interested in Marcus because he's more man than me…? It has nothing to do with the curse…?'

Then, his brain reached a far more logical conclusion. 'Or… Maybe I'm imagining things and she's not interested in him at all.'

…

'Yeah, that makes much more sense…! Because of Koneko, Xenovia, and Rias, I got a little too paranoid! If anything, isn't it good that there is no impact from seeing Marcus and Rias doing it? That means Akeno is safe! Otherwise, I might have to worry! This is good!' Issei psyched himself up.

Sona's explanation was a positive thing; Not negative.

With that understanding, he returned to his bedroom, cuddled up to Akeno, and fell asleep…

"Hmmm…?" Some sort of movement woke Issei up. "Akeno…? Where are you going…?"

"Oh, my. I didn't want to wake you up, Issei…" She was getting off the bed.

"Why not? What is it…?"

"I'm worried about Rias."

"Worried…? But weren't you the one who told me-"

"I couldn't stop thinking about it when trying to fall asleep. So… I'm going to her bedroom to bring her back to you."

"Bring her back?!"

"Yes. She'll be back in your arms by tomorrow morning. You'll be a couple again. Wish me luck." Akeno left the bedroom with a smile.

'Wow… My worries were COMPLETELY off-base!' Not only was Akeno the same as always, but she had a plan to bring Rias back to him, whatever it was!

The only odd thing was how she said that he and Rias would be a 'couple' again. 'She forgot to include herself… We're a throuple!'

An honest mistake, to be sure.

Chapter 2: Akeno Had A Duty

Chapter Text

Even if the man she loved would never say it out loud, it was obvious that she was second place.

Everyone knew, her included.

Still, she did not mind it. Sharing him was fine because she loved him so much… Or so she thought until she had him all to herself.

As it turned out, she hated sharing him, she just had not realized it yet.

And now that she had him all to herself, she learned one other thing.

…The gap between first and second place was a wide chasm…

Did no one realize she had feelings and could get hurt too?

'It's my own fault, really, for always smiling…'

Ultimately, she was willing to power through that chasm because she loved him so much.

How pointless did that determination turn out to be when she realized there was another man to whom she was much, much more attracted, and who was also not receiving the full attention he deserved?

She never thought sex was THAT important. To her, it was just a tool to show love; A duty to her beloved.

Now, though, she wanted to experience what it was like to receive that same love back.

'Carrying this huge set of tits has to have a purpose other than bothering my lower back. Oh, my! Someone has to use them well.'

Akeno was tired of being second place.

"Ugh…" Rias' consciousness slowly returned. 'I can't move… I'm… So tired… Nghh…' Earlier that day, she chose to finally give it up and have full-on sex with Marcus.

"Nghhhh ! Mnghh ! Unghh !" …It was still ongoing.

"Khhh…! Ghhh…!" Even after hours and several releases of plentiful volumes of sperm straight into her speared womb, Marcus kept on slamming and grunting, destroying her body with his massive muscles and huge black cock.

It was a truly surreal sexual act. The loud wet clapping that came from their swampy crotches colliding against each other was intimidating even for a strong girl like Rias. Their enormous difference in body size added to that intimidation. Rias was not small or petite whatsoever, but she looked minuscule before Marcus; Everyone did.

Perhaps most intimidating of all was his endless supply of stamina and cum, leading him to aggressively fuck and destroy her pussy even now.

'It's not gonna stop… Anytime soon… Is it…?'

PLAP! PLAP! PLAP! PLAP!

"Uuuuuuungh !"

Indeed, nothing indicated that a break was incoming. Marcus' pummeling remained as vicious and fast-paced as ever. The wet mashing indicated Rias had plenty of pussy juice left to go as well. Her body's ability to take on the giant and his big black cock surprised her.

Even then, Rias was incredibly sore and dizzy, with her vision equally blurry. She might have been getting sexually obliterated at the present moment, but she was not able to tell what sex position they were in.

It made no difference, really; it was not as if she could feel a thing beyond the soreness. No doubt, Marcus must have been battering the depths of her abused uterus with his huge glans; Even so, she felt nothing.

Nothing at all.

Her body was numb with exhaustion and soreness. There was only so much contracting that her muscles could handle; After a certain point, anyone would simply shut down.

Rias was mentally and physically done. 'I've had no break for days now… Ever since Marcus returned… But it's not his fault. It's all mine. I've been neglectful, trying to satisfy his urges with other forms of sexual pleasure. Of course none of it worked…'

Thighjobs;

Handjobs;

Boobjobs;

Blowjobs;

Rimjobs.

None of them worked for significant periods of time.

The Black King curse created urges that could only be sated with hardcore breeding sex. 'I realized that after the mess in the karaoke… The only way to really alleviate the curse is with raw sex…'

Rias did not know if Marcus required actual impregnation to calm down in full but doubted it. Devils had incredible difficulty becoming pregnant, and Marcus had calmed down SUBSTANTIALLY after a few cumshots inside her. 'I think it's just the act of shooting inside a vagina… Well… Maybe that and all the scraping… And squeezing… And pulsating… Nghh … How many times did he shoot in me…? Four…? That was too much… I can't even remember any of it… I lost it so quickly… I was already tired when we started, so I had no stamina left to go…'

Overall, Rias recalled little of the hardcore sex in the equipment room. All she knew was that she moaned LOUDLY and came HARD, with her vaginal cavity being stretched to its limits alongside her womb.

However, there WAS something she vividly remembered: All the lies she told to Marcus about being afraid of falling in love with him. 'I'm sorry, Marcus… I feel guilty about that, but you just wouldn't get going… I meant none of it…'

Rias wished that Marcus could just man up and take her ruthlessly without caring about her feelings.

Such a desire did not come from a fetish of submission or anything of the sort. Instead, it came from mental exhaustion and emotional ache.

It was so, so painful for her to proactively cheat on Issei.

Though she had broken up with him, she did not feel that way. In her mind, she was simply cheating, and that hurt her very much.

It hurt to cheat, and it hurt to hurt Issei. Every time she looked him in the eyes and saw his misery, she wanted to cry.

Because of that, Marcus' timidity and apologetic nature were so challenging for her. 'If he were more proactive and carefree about fucking me, he could just take me and I wouldn't have to feel as bad… But he makes me go out of my way to milk him, always apologizing and trying to make me stop… This is so hard on me…'

In the end, Rias had to bear the full emotional burden; A heavy and painful one. That was why she told those lies to Marcus, hoping that they would egg him on to fuck her senseless without her needing to further rile him up.

Her plan worked… But it hurt a lot to say such blatant lies, especially when they involved supposedly loving someone who was not Issei.

…

'How is he…?' Her mind wandered on its own to her loved one.

Was Issei sleeping well?

Was Akeno taking good care of him?

Had he gotten over her?

In part, she hoped for a yes; In part, for a no.

'Taking care of my peerage is my duty… I'm the only one who can safely handle the Black King piece without getting my body and mind warped and corrupted… I'll just have to tell more and more lies to keep Marcus going… Maybe… I'll have to pretend to be his girlfriend… And make him think I really love him… Would it be easier if I just fell in love with him for real? Is that even possible?'

Perhaps so, but she did not wish for it, wanting her heart to belong exclusively to Issei.

'None of this matters… Marcus is too shy and good of a person. He can't take charge and handle the guilt, so I'll bear it on my own. That's why I am everyone's master. I'll protect you, Marcus… Even if I have to hurt Issei. It's my duty.'

…But she really wished it was not. Rias would do anything for a way out, terrified of how much Issei would suffer if he heard the things she told Marcus in the equipment room. 'I don't want him to think I love another man… And… I don't want him to feel inadequate as a man.' For better or worse, Marcus did make her cum like crazy. 'Big black cocks are… Awesome .'

PLAP! PLAP! PLAP!

"Nghhhh ! Mnghhh ! Unghhh !"

'Ah… At least he manned up a little. He began fucking me in my sleep instead of making me start it. Marcus might be changing. This is good.'

PLAP! PLAP! PLAP!

"Ghnnn ! Uuungh ! Oooooh !"

'He's fucking me so hard that I'm not even feeling him right now. I've gone this numb? Amazing…'

PLAP! PLAP! PLAP!

"Hoooh ! Mnghooh ! Nghhh !"

'Wow… It's so hard that I actually can't feel a single thing on my entire body, and I'm moaning without even opening my mouth-'

…

"HUH?!" Rias opened her eyes wide and shot her torso up into a sitting position.

She was not getting fucked whatsoever!

"Nghhh ! Mnghoooh ! Oooooh !" There WAS sex happening…

PLAP! PLAP! PLAP! PLAP!

And it WAS very, very rough sex…

'BUT IT'S NOT ME!!!' She looked to the side to identify what was happening on the creaking bed.

Hardcore sex, of course.

Marcus was BRUTALLY fucking someone in a VICIOUS mating press, CRUSHING her body into the sheets as he drove his hips HARD into her, making the bed shake from each impact – much like the woman's thick ass and heavy tits shook.

As for who the woman was…

"Akeno?!"

Rias' close friend and second-in-command offered no response to her.

"Ooooooh ! Nghooooh ! Mnghuuuh !" How could she when every ounce of her being was busy getting railed harshly by Marcus' humongous, muscular, masculine figure?

In fact, even now, Rias could not confirm with 100% certainty that it was her. Marcus was so big that her body and face were concealed underneath him, sunk into the sheets due to their added weight pressing deep into the mattress.

Nonetheless, her hair and voice gave her identity away.

PLAP! PLAP! PLAP!

"Mnghoooh ! Hoooooh ! Nghuuuuh !" …DID her voice give her identity away?

Rias had never heard Akeno make such guttural, submissive sounds in her life.

Thus, the only evidence was her hair.

'No, there's no way…! Why would Akeno be having sex with Marcus?!' Rias desperately sought more evidence.

Thus, she examined the feminine hands failing to latch together around Marcus's sweaty back due to its width…

The thick, toned legs BARELY able to cross together around his waist, many times coming uncrossed and flailing about due to Marcus' FRENZIED pounding…

The SMASHED breasts splurging to the sides from how heavily Marcus crushed her body with his…

No new evidence surged, other than the hair.

…

Why did Rias continue to watch?

Akeno or not, she had to act, no?

The Black King could not be allowed to mate with anyone other than High-Class Devils because of the body and mind-altering effects of his semen. A woman tainted by contact or ingestion of his sexual fluids would have her body and mind become sexually warped in ways that were not readily clear due to how little was known about the Black King curse.

Only High-Class Devils could have sex with Black Kings without great risk, suffering minimal effects; At best, no effect whatsoever.

…So why did she watch for so long…?

'Wow…' Her hesitation had nothing to do with exhaustion or soreness. 'This is…' She was simply fascinated by the AMAZING sex occurring in front of her.

Rias was as feminine a woman as any other, even if she was in a position of powerful leadership.

…Seeing such a physically masculine and attractive male sexually OBLITERATE another woman stirred something deep within her…

'Is that how it looked from the outside when he fucked me…?' Rias recalled so little of the sex in the equipment room that she could not draw a proper mental comparison. She remembered the strong pleasure, naturally, but so little of the act itself.

Seeing it with a calm mind was a whole experience in and of its own.

…She felt a strange pride for knowing that Marcus had spent so long using her body like that…

Rias remained in that state of unintentional hypnosis for multiple minutes, watching the massive, manly Marcus aggressively drive his hips into the woman crushed underneath him, until something called her attention.

Where did the guttural wails go?

"Ghh! Khh! Nghuuuh!" Marcus began grunting so loudly that his voice vastly overshadowed the woman's moaning.

Why was he grunting in such physical strain? Everything indicated that he had full dominance over the woman underneath him. If anyone were to be howling maniacally, it should be solely her. Marcus was more than muscular enough to be able to crash his hips into any woman for a full day if he so wished.

What could possibly consume so much from a strong man like him that he would involuntarily grunt so desperately.

Right then, perhaps by instinct, Rias took note of Marcus' GIGANTIC, HEAVY balls.

They stored vast volumes of thick, rich cum; She would know, having swallowed dozens of dense, creamy loads from him. Each one was equivalent to several from Issei, and each one was a challenge to swallow, often making her gag and choke due to density. One time, she even had to stop sucking to puke on the floor, but not because it tasted bad; Rather, because she nearly choked unconscious from how obstructed her throat became.

…On the matter of taste, it was actually the best drink she had ever had…

'I wanna drink some…' Rias thought automatically, distracted by the beauty of the two heavy balls swinging again and again against the woman's ass due to the force poured behind each slam. The crashing sounds were an orchestra of their own, making her feel intimidated and aroused.

…She tried to remember if the collisions were that wet and loud when it was HER pussy getting deliciously smashed by his-

"KHHH…! GHHH…!" Marcus' grunts summoned her attention again, this time with her knowing what was happening.

Marcus was raping the woman – most likely Akeno – and was about to ejaculate inside the woman! He had lost himself in a cravings-fueled rush due to his curse!

It was an urgent matter that had to be stopped at all costs!

"Marcus! Stop! STOP!" Rias snapped into action, screaming.

"Master?!" Marcus was surprised enough to stop thrusting and look her way.

PLAP! PLAP! PLAP! PLAP!

…For a mere second. "Khhh! Ghhh…!" He was too close to release to fully halt his movements. The tensing of every muscle across his body and throbbing of his balls were proof of that.

An outburst of CREAMY semen was imminent, and nothing could stop him. Marcus' desire to ejaculate was a force of nature when the finish line was so close.

Still, the small interaction did provide Rias with two useful pieces of information.

Firstly, Marcus had raised his head just enough to look at Rias, exposing the face of the woman under him: It WAS Akeno.

Secondly, she was certainly getting raped against her will. The exhaustion on her face must have meant so, even if there was also plentiful euphoria as well. Based on the sweat across her body and the exaggerated tension of her neck muscles, she must have been so drained that breathing had become a life-threatening challenge; Having her face buried in his muscular chest probably added to the oxygen deprivation.

Therefore, Rias could not give up. As heir apparent to the Gremory Clan, she HAD to rein in the Black King piece that she brought to the world.

"Marcus! STOP! You can't rape her!" She infused her voice with authority.

"I-I'm not-"

"Stop."

"Ghh…! Yes…! Khhh…!" He clenched his teeth hard; His face tensed up.

Release was seconds away; Rias was ready to pull him out by force if she had to.

Thankfully… "Ghh…!" …He motioned to pull out on his own, fighting every urge in his body.

That made Rias smile; Marcus was a good person and wanted to cooperate. No doubt, it must have been IMMENSELY challenging for him to pull out. Nonetheless, he was succeeding!

He pulled out-

BZZZZZZZZZZZZZZZZZZZZZZZZZZZ!

"KHHHHHHHH!!!" Marcus stopped pulling out, jittering in place.

It was almost like he was being…

'…Electrocuted?!' Rias stopped focusing on his face to look at Akeno.

"Oh, my…! Please don't leave… Hah … When you were just about to… Hah … Show me how much you enjoyed my body… Hah … Marcus !" Akeno panted in-between words, breathless. She had both index fingers touching Marcus' nipples to jolt him. "Ooof!" Perhaps a little too hard, resulting in Marcus collapsing on top of her, still jittering.

And then, probably without conscious input by him…

PLAP! PLAP! PLAP! PLAP!

"Mnghoooooooooooh !!!" …His hips resumed PUMMELING Akeno.

Rias was so stunned that she did nothing but watch wide-eyed.

Why had Akeno done that? Who was raping who?

Those were relevant questions that would not be answered at that moment due to a more pressing matter.

"GRRRRRRRRRRR!!!"

"Uuuuuuuuuuuunghhhh !!!"

A POWERFUL, MASCULINE release of sperm was occurring, taking preference over every single worry in Rias' mind. She observed slack-jawed and wide-eyed as Akeno's flat stomach turned into a small belly from how much cum poured into her womb, expanding wildly to accommodate the total volume. It had grown large enough to almost conceal the massive bulge created by Marcus' penis lodged deep inside her.

"Nghooooooooooh !!!" Marcus was not the only one cumming. If Akeno's wails were not obvious enough, Rias could also draw proof from her own vague memories of the equipment room: Whenever Marcus ejaculated inside her, she came the hardest.

…There was an inexplicable satisfaction in feeling her tight, wet pussy squeeze cum out of such a virile male…

'I wonder if she feels that way too…?'

"Ooooh … I love it … It feels so good … Keep pumping cum into me … You stud … Yeeees … Uuuungh … I'm gonna burst open … Your cock's trying to spear out of me … It's shaking so much … Thank you for making good use of my pussy … Let all the nut out … Hoooh …" Akeno answered that question pretty directly all on her own, gently massaging Marcus's sweaty, bulging back with trembling hands and toe-curled feet.

All in all, Rias was amazed. Akeno had handled Marcus so much better than her despite not being a High-Class Devil.

"Uuughn … Mgnhhh …" And then reality came crashing hard, with Akeno ceasing her praise and letting go of the intimate hug. Her quivering body went limp, drained of all energy to keep going.

"I'm so sorry…! I'm sorry…!" Without Akeno to zap him, Marcus pulled out with ease, drawing one last squirm from her as his cock scraped her throbbing insides on the way out.

"MNGH !"

"Sorry! Sorry…! I didn't mean to finish inside her...! I tried to pull out…! I'm sorry…! I don't want to hurt anybody… It's all this horrible body's fault… I hate it…" He teared up; Meanwhile, his cock remained hard, veiny, and tall, oozing final spurts of cum that added powerful odor.

"I-it's okay… It's okay… I… Uh…" Rias did not know what to say, confused about what was happening. "H-how many times… Did you cum inside her…?" She observed Akeno's euphoric, drained face and twitching, exhausted body. There was a dense river of cum flowing out of her gaped-out pink slit.

At least five times, Rias assumed. It was the only way to explain how the athletic, strong Akeno could be so physically spent. 'When he fucked me, I lost it right away, but I was coming from days of nonstop milking him without sleep. She's all rested up, so-'

"Just once! I swear!"

"ONCE?!"

"I swear!"

'Ridiculous…!' The curse was as strong as Rias estimated. 'Only High-Class Devils can safely have sex with Black Kings… So why is Akeno here?'

"It's all my fault, Master! I accepted her offer!" Marcus offered an explanation.

"Offer…?"

"While you were asleep, I started feeling that horrible pain again, but I didn't want to wake you up because of how tired you must be! Then, there was a knock on the door! I went to check it and Ms. Himejima offered to have sex with me. She's the woman you trust the most, so I thought it was okay. I didn't want to push you more after… After how much I hurt your body at school earlier… It's all my fault…! She started rubbing her boobs on my crotch and I couldn't hold back…!"

"Marcus… What about the promise you made me? You said you'd stop holding back and use me like a whore to pump your cum into…"

"I'm sorry…! I couldn't hurt you like that when you looked so tired…!"

"I-it's okay… Hah…" Rias was tired of Marcus' apologetic nature. 'Please man up a bit… Match your body with your spirit…'

"That's right… Hah … Hah … It is my fault, Rias. You don't need to scold him over it…" Akeno raised her torso into a sitting position, turned to face Rias, and tried to look into her eyes.

'Tried' because her eyes were still crossed, her breathing was still ragged, and every inch of her body was still trembling.

"A-are you… Still climaxing…?"

"Oh, my, am I? Nghhh … Maybe… Ooooh …" Her vaginal lips BLATANTLY confirmed a STRONG orgasm, twitching so wildly that they flapped into very quiet wet claps multiple times.

Most people would usually say that seeing was one thing and doing was another. This statement could be applied to any activity in which there was a big difference between expectation and reality.

For Rias, it was the absolute contrary.

Having sex with Marcus was one thing. Seeing what the sex was like and its impacts as a third party was another.

…It was amazing…

…Marcus was so, so masculine…

…Akeno's sweaty, spent body was a work of art…

"Akeno, are you okay…?"

"Do I look not okay? I just had the pounding of a lifetime. I don't think I knew what an orgasm was until now. You were having quite the fun all by your lonesome with Marcus, weren't you, Rias…?" Slowly, Akeno's gaze recovered its focus, making eye contact with Rias. Even so, her voice, breathing, and body reeked of exhaustion.

"I don't understand what's happening here…"

"Rias. Why don't you go back to Issei?"

"…Huh?"

"Leave Marcus to me. Go back to Issei."

"What are you talking about, Akeno?!"

Akeno silently stared at her for several seconds, upholding her usual smirk.

Then, for a very quick moment, that smirk broke into a wince; One that did not last long but told the full story of Akeno's feelings when taken into consideration along with her next words. "Oh, my, can't you tell? I'm not enough for Issei."

"Heh?"

"He wants you, Rias. Let's swap."

"What are you talking about?!"

"Wasn't I obvious enough? What else do I need to say?"

"You're not making sense to me! I asked you to take care of Issei! And… And it's my duty to protect Marcus and everyone else!"

"Rias… Issei doesn't want me to take care of him. He loves you much more." Even if smiling, there was a tinge of resentment in Akeno's voice.

"That's not true! He loves you too!"

"Oh, my! I guess being in second place does count as love. But, you know, it can be a little tiresome…"

"I… I didn't know you felt that way…"

"Oh, my! I didn't mean to gain pity. I am just being honest."

"…"

"Go back to him. I'm offering you a way out."

A way out; One back to Issei.

Those words resonated with her on a deep level.

Rias wanted a way back to Issei.

"I can't do that. It's my duty to take care of Marcus…"

"Is there a point to repeating that so much, Rias?"

"Hm…?"

"Everyone can see you're hesitating. It's not hard to understand. You love Issei, just like me, right?"

"…"

"If you hesitate so much, you just end up neglecting this big guy here, don't you…?" Akeno looked at Marcus and grabbed his penis, giving slow strokes to its cum-coated length. "It's still got so much vigor left . A masculine piece like this isn't getting satisfied by a woman who can't commit, High-Class Devil or not."

"That's a lie! Master has been great to me…!" Marcus defended Rias.

"Oh, my! This one is in love with you, Rias. Aren't they all? And here I thought my bigger tits gave me an advantage. Even big black cocks prefer you, hm…? But, say, Marcus… Wouldn't you feel better if you got to fuck the pussy of a girl who you don't have to feel guilty about?"

"Uhm…" Marcus averted his gaze.

"I know you feel bad. You wouldn't have to feel bad with me. I'm very excited to become your full-time cock caretaker . You could sink your strong hips lots and lots against me without any remorse… That's important when you have so much vigor and muscle, right…? No need to hold back with me. Didn't you love how my cervix caved so easily…? My womb wanted you to access it. You can use these a lot too …" She used his cock like a stick to smack her fleshy breasts with; Sweat and cum splashed from the impacts, producing small echoes from the collisions.

"Ghh…" Marcus trembled. Even if his urges were sated, he remained hard and ready to go. Most likely, he still needed a lot more raw sex to be fully satisfied for any relevant period of time.

"Akeno, that's…"

"Rias. I can take better care of him, and you can go back to Issei. Isn't that simple enough?" For once, Akeno stopped smirking. For a woman like her, it was a sign of intense seriousness – and slight annoyance.

"How am I supposed to just accept that? You know about the Black King curse. I'm the only one who can safely have sex with him. If you do, the curse will affect your body and mind…! Even what you two did now was already too much…! Especially with…" She glanced at Marcus' erect, wet cock and balls. "Especially with how much he shoots each time…"

"It's already bound to happen, so who cares?"

"What?"

"Rias, you've been doing a bad job. Have you been paying attention to Xenovia? Or Koneko? Aren't you already losing control? Isn't your hesitation compromising the peerage?"

'Xenovia and Koneko…' Rias thought back to the karaoke's bathroom. 'How did things get to that…? I was so distracted licking his ass that I didn't notice Xenovia entering the stall and deepthroating him until it was too late. He came so much inside her throat, and then she kept sucking and sucking… I couldn't pull her off him. And Koneko… What was she doing staring from over the neighboring stall…? Tch…' As much as Rias hated to admit it, Akeno's words rang true: She HAD been doing a bad job due to her hesitation.

"M-Master…" Marcus felt self-conscious and hurt, not okay with the idea that Rias should be forced to have sex with him. Circumventing that anxiety was the whole point of the lies she told him in the equipment room about possibly developing feelings of love for him.

There were no feelings of love.

Mind-numbing sexual ecstasy as a woman, yes; Love, no.

"You see it too, don't you, Rias? If you're going to keep doing a poor job, why not centralize all the cursed semen in me?"

"Centralize…?"

"Yes. In my pussy." She jerked Marcus harder, adding constant squelching to the background from how tightly she gripped his penis and tugged. It was a small act that transmitted a great deal of commitment. Akeno truly had no hesitation, wishing to become Marcus' full-time cum bucket. "I'll let this beautiful, manly big black cock nut inside me as much as it needs to satisfy the curse."

"But…"

"It's okay, isn't it? I've always been a little annoyed by how big my tits are. People stare, choosing clothing can be hard, bras don't work, and they weigh so much on the front… But I forgot all of that because Issei liked them. Suddenly, I feel annoyed about them again."

"What does that have to do with anything…?"

"Oh, my! I suppose you wouldn't get it. There is such a gap between first and second favorite, isn't there? A woman like Rias never feels wasted." She tilted her head, smirking with a voice coated in sarcasm.

"I DON'T get it. But if you're talking about size, isn't this bad for you? You'll probably grow with the curse…"

"I don't mind it because this guy is going to make full use of my body, right, Marcus…? In fact, I want it… Retool my body as much as it needs to keep up with this hung boy . It'll be worth it. I'll use my fatter tits to milk this big black cock lots and lots …"

SQUELCH…! SQUELCH…!"

"Nghh… I-I…"

"Isn't his timidity so cute? Please forgive me if I devour you with my big titties, okay, Marcus? You just make it so fun to tease ."

"H-hah…" Marcus quivered as Akeno's handjob proceeded without pause.

Even after so much talk, Rias still did not understand. "Don't you love Issei anymore?"

SQUELCH…! SQUELCH…!

"Khhh…! Hah…!"

"Akeno?"

"…Pointless boredom is pointless." She answered without looking away from Marcus. Her gaze moved up and down, going from his strained face to his throbbing, veiny black cock. As a dominant woman, she adored seeing the giant shudder with her touch.

"Pointless boredom…?"

"Imagine my surprise when I learned how amazing sex can be with a big black cock… Wouldn't it be fun to feel sexually fulfilled for once?"

"…" Rias did not entirely understand Akeno but found herself wanting to accept the proposal. "But the curse..."

"Rias, Relax. I'm your Queen piece. I am strong. I can handle Marcus and won't become warped."

After that confident declaration, an eternity passed in Rias' mind.

Did an eternity pass outside her mind too?

It was hard to tell, but she vividly observed Akeno's hand rush up and down dozens of times, milking the life out of Marcus' rigid, tall, veiny black cock with plentiful eagerness, strangling a future orgasm out of it.

Rias had shown that same eagerness several times, even when rimjobbing Marcus – a record of erotic filthiness for her times.

…But it was fake, and Akeno's eagerness was not.

"If… If I do accept, you'd have to promise that you won't let the curse spill to the others."

"That's a given. I'll do a much better job than you at keeping this sexy black boy satisfied. Oh, my! Please don't get jealous." She laughed playfully.

"If… I accept… What am I going to tell Issei? He'll be hurt that you left…"

"What to tell Issei, huh…?" Akeno averted her gaze from Rias again, focusing on the wet, hard cock being milked. "He won't care. Tell him whatever."

"Of course he'll care!"

…

"Do you really think so…?" Akeno side-glanced at her, blushing.

"Absolutely…!"

…

"Well… Then… If you really think he'll care…" Akeno blushed harder. "Why don't you tell him that we switched because you want to find a cure but need the freedom and time? That might make him not feel so bad… How you'll fix that lie later is your problem. I'll keep it on my end… I'm sure Marcus will too, right…? We won't tell the others to avoid causing a ruckus."

SQUELCH…! SQUELCH…!

"Khhhh…! Ghh…!" He nodded with clenched teeth. Akeno's pumping grip was mercilessly tight.

"P-promise?" Rias asked.

"Promise." Akeno nodded.

…

Something still made Rias hesitate: Marcus. 'Is he angry with me…?' She nervously glanced at his face.

Marcus was not angry.

Just sad.

"It's okay, Master… I understand… Ghhh…" Akeno did not pause the handjob for even a second. "You love Issei and I'm getting in the way. Nghh… Everything is my fault. I hate this body and everything that's happening because of it… I don't want you to be unhappy because of me. As long as you don't hate me, I'll be fine with Ms. Himejima… So, please go. Khhh…" He forced the worst of fake smiles to give Rias courage.

…

There was no more reason for Rias to hesitate.

…So why did she not leave already?

…Was it because she remained captivated by the sexual allure of Marcus' hypermasculine body…?

…She wanted to deny it, but looking at his big black cock made her pussy throb…

…Rias was a woman before being a Devil…

"No more looking!" Akeno got in the way with a petty smile. "He's all mine now! No stealing my man. You wanted Issei, so Marcus is all mine now! Right, Marcus?"

SQUELCH! SQUELCH! SQUELCH!

"Nghhh…! Ghhh…! Yes…! Ms. Himejima…!"

"Oh, my! It's Ms. Akeno from now on, okay? We'll be intimate from now on."

"Yes…! Ms. Akeno…! Ghhh…!"

"Isn't it cute how such a big boy can shake so much? I think I'll let him blast the next one all over me. My body is not suited to take consecutive shots directly in the womb yet. Rias, would you leave? You're getting in the way."

Rias did just that. Without making eye contact with Marcus, she got up, put her pajamas on, and walked all the way to the door.

It was not a quick walk. Every step felt so, so heavy.

She wanted to get back to Issei but felt that if she walked through that door, her heart would be so overtaken by cowardice that she would not be able to come back.

Taking care of the Black King piece was her duty. If things got out of control, what would she do? 'I can't break up with Issei twice. It would destroy him!'

Rias looked back one last time.

Akeno had already shifted gears, adjusting herself on top of Marcus' lap to take his cock in a cowgirl position. Her dominant, overbearing demeanor was a perfect match for his passive, needy self.

'Akeno is strong! She can handle him! I know it!' Confident, she walked out the door.

Rias trusted Akeno.

"Get ready, Marcus…! Sorry for being so bold, but I'm gonna ride your balls dry, okay?! Oh, my, I'm excited…!" Akeno adored admiring the big statue of muscles underneath her as she adjusted the tip of his erect penis against her slit. "Are you ready…? I'm gonna go wild now…!"

"Y-yes…! Thank you, Ms. Akeno…!"

"You *better* thank me. I'm going to give you dedication and commitment that Rias was not willing to, so make sure to show me the same back."

"Yes…!" Marcus nervously said.

"Be ready to witness a spectacle. I'm going to make this cock go crazy inside me." She fully believed in her ability even after having lost it just a few minutes ago. 'If I focus hard enough, I can do it.'

Akeno bit her lips, readied herself, and sank her hips HARD, blowing past her pre-pried cervix; The back of her womb was immediately impaled deeper into her body as his HOT, HARD glans hit it.

"NGHOOOOOOOOOOOOOOOOOOOH !!!" Next, she wailed very, very loudly as an EXPLOSION of pussy juices blasted out of her stretched-out pussy.

And after that…

…

Darkness.

Akeno passed out.

"Koneko…?" Rias bumped into the petite white-haired girl upon walking out of the room.

"…" Instead of greeting Rias, she tried to look over her side to see inside the room. "…You closed the door too quickly…"

"What? What are you doing here?"

"Guarding the door for you. Keeping an eye out for Issei."

"I didn't ask you to do that tonight."

"Ah, is that so? But I did it anyway."

"Huh...? Okay…? Then… You can go to bed now."

"You're stopping…? No more sex with Marcus tonight…?"

"I… Akeno is with him now."

"Nghhhhuuuuuuuuuuh !" A hoarse, desperate howl came from inside the room with perfect timing. Because of the thickness of the door, it was significantly muffled.

"Akeno…" Koneko glared at the door. "I see. Goodnight, then."

"Goodnight." Rias walked down the hallway.

…And then stopped, looking back after realizing she could only hear her own steps.

Koneko was not leaving. Instead, she was gluing her ears to the door and rubbing her legs together.

On its own, that was weird enough.

That said, the weirdness peaked a few seconds later when something changed on her face.

The way her eyes twitched, her breathing accelerated, and her lips pursed…

…

'…Is she feeling pleasure from… Listening…?' There was no spell currently active to conceal the sounds of sex within the room. Therefore, Koneko might have been able to hear something – even if not much, considering the size of the bedroom and the thickness of the door.

Something might have been seriously wrong with Koneko.

Rias realized that when she saw a stain form on the small girl's crotch.

…Dripping on the floor…

Rias and Issei did not say a single word to each other at first. As if they could read each other's minds, they simply ran to each other and hugged tightly.

"I love you, Issei…!" Rias said in tears. "I missed you so much! D-do you still love me?"

"Of course I do!"

"I'm so happy to hear that! I thought you might hate me…"

"No way! I love you! B-but what are you doing here?! Are you… Uhm… Are you here because you want to get back together…?"

"Yes! Yes, please! I want to be with you again!"

"Hah…!" Issei almost cried as well.

"I love you…! I love you…!" His passionate reaction warmed her heart, sending her into another burst of tears. 'I had to steel and ice myself so much to handle everything…! I'm so happy he still loves me…! I'm so lucky…!'

"President-"

"I'm sorry for everything you had to see, Issei! I hurt you too much! It's all my fault! I'm so sorry!"

"S-stop…! I know! I understand everything! It was my fault for making it worse for you! You… You were just doing what you had to as our master… I just want to know if you're really back!

"Yes! Yes!"

"Ah…! I can't believe it…!" A huge smile formed on his face. "What about Akeno? Where is she?"

"A-Akeno, huh…?"

"Yeah, where is she? And how are you back? What about Marcus? I don't understand. Akeno said she'd bring you back, but she didn't give me any details."

"Sh-she said that, huh…?" Rias knew her moment of pure happiness would be short-lived. 'I have to steel myself once more to lie…'

…

…

…

"I can't accept that…! Even for a cure, I can't accept Akeno sacrificing herself like that…!" Issei reacted to the lie as well as she expected him to. "I need to talk to Akeno right now! She didn't tell me she would do that! There's gotta be another way!" He broke from their hug and stormed toward the door.

Rias should have stopped him but could not find it in herself. 'This all is my fault… Huh…?' To her surprise, Issei stopped on his own.

"…I… I don't want to make the same mistake again."

"Same mistake…?"

"Akeno must have done this because she felt ignored by me… I should have cherished her more…"

'I didn't expect this much perceptiveness from Issei… Woah!' She shuddered from a sudden tight hug.

"I'm not making the same mistake twice! I'll just accept that you're back and that the situation is what it is, President!"

"Ah… Y-yes!" She did not fully understand what happened to Issei while they were apart, but one thing was clear: He had grown in some way – a convenient one that allowed her lie to flourish. If Issei insisted on not accepting Akeno with Marcus, the truth would have easily been exposed.

"Is it true, though?! Is there really a cure for Marcus' curse?!" Issei glared at her. His eyes BEGGED for a 'yes'.

"Yes." So, she lied again.

"So it's just temporary! You're going to cure Marcus and everything will go back to normal! Akeno will come back! And I can then apologize to her!"

"Y-… Yes. But don't talk to anyone about it yet. It's… Uhm… A secret."

"Okay…! Okay, I can work with that. I won't cause more problems! I'll trust you and hold on! As long as needed!" He hugged her again.

One more time, she shed tears, now with her face buried in his chest. 'This lie isn't gonna last for long… Why did I double down so hard on it…?! What am I gonna do?! Ah… I don't know… I turned into a coward… I just want to enjoy this moment...!' She hugged him back harder than ever.

It was a long, long hug.

So long that she felt like something was missing.

What was it?

'Ah… He's got no bulge in his pants pressing against my legs. That's okay. I don't miss it… Size and masculinity don't matter to me. I love Issei for his personality.'

"Hey, what are you doing, President…?"

"Hm? What?"

"You're rubbing your legs against mine a lot."

"Ah…"

Maybe she missed it a little.

That morning's breakfast felt like the most important one of Rias' life. 'Let's see how things go with the swap…'

There was no strict schedule or rule for breakfast. Everyone usually gathered at more or less the same time and ate whatever they wanted – except on the rare days that someone cooked breakfast for everyone.

Right now, Rias was sitting and eating with Issei beside her.

On the other side of the table was Marcus, who seemed physically healthy. 'I think Akeno helped sate him well throughout the night. That's good.' Mentally, it was unclear whether he was fine or not, though the awkwardness was blatant, going out of his way to avoid looking at Rias. 'It must feel like a break-up to him… I hurt Issei and now him… But things will get better from here on out. I'm nervous about what Issei might-'

"Marcus." Issei said.

"H-hm?"

"I'm sorry for being so mean these last few days." Issei got up and bowed.

Everyone looked with surprise: Marcus, Asia, Xenovia, Koneko, and Kiba. Akeno was not present yet.

"Please forgive me for everything I said in the karaoke that day. I want to accept you in the peerage and be friends too, like everyone else."

"Issei…!" Rias girlishly brought both hands to her mouth, in tears.

"Issei…!" The hypermasculine Marcus girlishly did the exact same thing.

Issei walked over to Marcus and hugged it out with him.

'He's such a man! I'm so proud of you, Issei!' Rias thought with a big smile. 'Marcus is so much bigger and manlier-looking… Look at that huge bulge in his pants …' …While her mind brought other intrusive thoughts to the fold at the exact same time. 'What?! Wh-what was this thought?! I love Issei! I can't think that sort of thing…!'

Was it the curse?

…Had Rias been impacted…?

Issei sat back down and breakfast proceeded without a hitch for the next several minutes.

Rias was very, very hopeful that things would pan out well. 'Without Issei going off on Marcus, his stress should be minimized! Akeno can handle him just fine! I don't know what I'm gonna do about the lie yet, but I'll come up with something. For now, I want to enjoy this moment of-'

"Ghlrrrrrrgh!!!" Xenovia abruptly made the loudest of sounds.

Choking.

"H-hey, is she choking on food?!" Rias got up to-

"Bhlrrrrghhh!!! Ghlungh! HAH… HAH… HAH…" She swallowed it all down, panting for air after her face had been painted a DEEP shade of red. "Hah… Hah… Hah… That was a good one… Hah… I still feel my throat all stretched… Hah…" She kept her head thrown back and slowly massaged her neck.

…Squeezing it strangely hard…

Why did it look like Xenovia was strangling herself after having almost choked on food?

In fact… "…X-Xenovia… Why is there so much food on your plate…? And… Why do you have five bottles of soda on your side there…?"

"Huh? Oh, I'm just really hungry. Thirsty too. I don't know what's been going on, I guess I'm having a phase. I just can't eat enough! Fuck, fuck… I can't fix this itch…! Ghhh…!" She continued to massage – or MILK – her neck, running a tight grip up and down its length. "Someone needs to go grocery shopping. I think I ate almost the entire fridge last night."

"Y-you ate during dawn?"

"Yeah, why? I'm just really hungry…! No, no, that's not it… I mean, I'm hungry, but it's this itch…! Ghhhh…! God, I need to shove something down now…! It's making me go crazy…!" She resumed eating and drinking.

Or, rather, DEVOURING like her life depended on it.

There was something curious about the way Xenovia ate and drank: Each time, she worked hard to stop the food and drink deep in her throat before swallowing. 'It's like… She's trying to rub her neck from the inside…? Isn't she shoving too much food down at a time?! Why is she eating so much anyway?! Shouldn't she be getting super fat?!' Rias examined Xenovia's figure. 'Hey… When did she put on all that muscle…? Aren't her boobs a little bigger too…? I think she gained a bit of height… And now that I'm paying attention to her…'

…Why was she glancing at Marcus every few seconds?

There was more to it too. The timing of her glances matched perfectly with every moment that she stopped the food and drink deep in her throat.

Was she trying to relive certain memories?

…Memories of vicious throat-scraping and cum-pumping straight into her stomach…?

'She drank a lot of semen, didn't she…? Xenovia might be affected. Is that making her build muscle and become obsessed with oral stuff…?' Rias gulped down, nervous about a potential severe problem within her peerage.

Xenovia was not the only one. She looked at Koneko next.

'What is she doing…?'

Koneko was glaring nonstop at Marcus, to the point that her eyes were bloodshot from lack of blinking. Moreover, she slowly inched her chair closer and closer to him while subtly taking sniff after sniff of air.

Why? There was no special smell in the air, was there?

'C-creepy… Koneko, blink, please! Why are you staring so much at him?! Marcus can tell, you know?!' The large black man looked left and right intermittently, uncomfortable with Xenovia's glances at Koneko's creepy glare.

Next, Rias examined Asia.

NOTHING out of the ordinary. 'Asia, you're a good girl! Please never change…! Kiba, you too, right?'

Kiba seemed well, though he looked at Marcus and the two girls often, no doubt out of discomfort.

Seeing them well reinforced Rias' optimism. 'Maybe Koneko and Xenovia have been somewhat affected, but that's okay… Maybe if they don't have contact with more of Marcus' semen, they will regress back to normal. I have to stay strong for now. I trust Akeno more than anyone else, so it will be alright.' Rias was confident that rock-bottom had been long since reached.

"Where's Akeno?" Kiba asked.

"Ah… She's… Sleeping, I think." Marcus answered.

"Huh? Why would you know that?" Kiba had directed his initial question at Rias.

"Because… Uhm…" He looked down, unsure how to word last night's change to the others.

"Did you and Akeno do it last night?!" Xenovia exclaimed, devouring food and chugging down soda in-between words.

"…Yes… Rias and Akeno swapped last night for some reason…" Koneko exposed reality, refusing to blink even once, still inching closer to Marcus.

"Heh? You're no longer taking care of Marcus, Rias?" Asia asked, confused and scared.

"Did something change?" Kiba was the only one maintaining his cool – other than Issei, who knew the 'truth'.

"Hey, hey, hey! *I* just asked a question! Can I get an answer?!" Xenovia brought the focus back to her, sweating and glaring. "Did you?! Did you?! Glrrghhh! Kuh! Kuh!" She choked on food again, coughing hard between words.

The purpose of her question was self-evident to Rias. 'I think Xenovia might have gotten addicted to his semen. She's trying to figure out if everyone's now allowed to have sex with Marcus. Look at how much she's staring at his crotch…! She's drooling while munching on food! This is bad. I want to say she shouldn't be so affected, but she drank a lot of his semen those two times… I should have stopped her. What should I say now…?' Rias scrambled for a public statement to give since Akeno was not there.

"Just tell me! Is it a free-for-all now?! Can anyone suck his big black cock?! I just wanna-"

CLAP!

"Calm down, everyone!" Akeno entered the room, clapping her hands loudly together to silence Xenovia's agitation; There was a limp to her steps. "No one said anything about a free-for-all. No sucking my boyfriend's big black cock off, okay, Xenovia…?" She hugged Marcus from behind, resting her face on his shoulders, gluing cheeks together. He was so tall that she was unable to press her chest against the back of his head even with him sitting on a chair.

Everyone reacted with surprise at the 'boyfriend' announcement.

"You see, while you were all distracted with your daily lives, Marcus and I were secretly forming a bond… And now we love each other, right, Marcus?" She gave him a pecker on the cheek.

"That's… That's right…"

"What about Issei?!" Asia cut in with a shout of her own.

"Oh, my! Asia, you're such a good friend, caring for Issei's feelings. Well, isn't the answer to your question obvious…?" Akeno looked at Rias and Issei. "Look at them so close together. Rias and Issei are back together, and Marcus is with me now. No one can have him but me, okay…? Because I am a possessive lover. I'm Marcus' number one, and no one can tame his big black cock as well as I!" She gave him another pecker on the cheek.

While everyone reacted with differing levels of surprise – with Xenovia being the most disappointed one, and Koneko the most indifferent one – Rias examined Akeno's face and demeanor.

Something was off. 'It's very subtle, but… I feel like there's a hint of malice in her voice… Why would there be? I must be imagining things. Though… I don't think I imagined what I saw when she walked in, did I…?'

Akeno's nipples were blatantly erect when she entered the room, protruding through her shirt even though she wore a bra. Moreover, her breasts seemed very slightly fuller.

Could she have been influenced by Marcus' seed from only a single night of sex?

'That's impossible. No way-' Rias' confidence was crushed by memories flashing before her eyes.

Or, rather, a distinct lack of memories caused by sex so rough that she quickly went mindless in the equipment room yesterday, only to wake up with a river of cum stuffed into her womb.

Just like that, 'impossible' turned into a silly word. Without having Rias' protection as a High-Class Devil, Akeno could have easily been affected already.

…

'I'm imagining things.' Rias opted to deny what she saw. 'Heh? Oh, everyone is looking at me…!' She refocused and grabbed Issei's hand. "I never stopped loving Issei. Circumstances made us break up temporarily, but everything is back to normal now. Akeno is with Marcus and will take care of his needs… Because they're boyfriend and girlfriend and love each other now. And about the curse… I'll talk about it another day, but no one needs to worry."

"See? There you go, everyone." Akeno offered a wide smile.

…With a tinge of annoyance and frustration behind it? 'Isn't she looking at Issei a lot…? Why…?'

"I am very happy being Marcus' cum depository. You're happy too, right, Marcus? Aren't you happy to have an even bigger set of tits to use now? Isn't it wonderful that you can dump your wonderful seed all over them whenever you want…?'

"Y-yes…" Marcus reluctantly nodded, side-glancing at Rias. He made a poor effort at hiding his true feelings, which made her feel guilty. Marcus had genuine feelings of love for Rias. As beautiful and sexually dominant as Akeno was, she could not overtake those.

"…" Akeno smiled even wider, again looking at Issei and Rias.

And then…

"Ghlrrrrgh…! Bhhlrrrrrrgh…! Khhhhhhhh…!" …Xenovia entered another episode of creepy, life-threatening choking, with so much food distending the shape of her neck that it looked like she was trying to kill herself via suffocation.

"I got you- Huh?" Kiba shot to his feet to help Xenovia, but she raised a hand to stop him and started PUMPING her neck with her other hand; Soon, with both.

Everyone watched in shock as Xenovia jerked her food-distended neck like she was trying to milk it, break it, or strangle it. It was a gut-wrenching sight that made everyone uncomfortable – except for Koneko, who did not look her way, still concentrated on Marcus.

"Ghlrrrgh…! Bhlrrrrgh…!" It kept going and going. Xenovia refused help even as her face grew dangerously pale due to oxygen cutoff. Within seconds, her lips would start becoming blue. Veins popped all over her face from the pressure that came with lack of air and an overstuffed throat.

"Out of the way!" Kiba smacked her hand, hugged her from behind, and performed a Heimlich maneuver.

"HAH … HAH … HAH …" Soon enough, Xenovia found herself frantically gasping for air.

"Are you okay?!"

"Why did you do that…? Hah … I was almost there…! Almost there…! I was almost scratching that itch…! Ghhh… I'm hungry…!" It took her no time at all to start devouring and chugging again.

…And glancing intensely at Marcus and his crotch.

Had Xenovia almost orgasmed from choking herself with food?

Rias wanted to think it was the creepiest thing she had ever seen, but it was impossible to ignore the cat girl on the other side of Marcus.

Koneko had fully inched toward him, now silently resting the side of her face against his massive biceps.

…And was trembling so, so much, with tears almost coming out of her eyes. The drool leaking from her mouth exploded in volume, and her nostrils sniffed even more aggressively. Koneko was breathless for no reason at all, blushing and shuddering slightly.

Rias' peerage was contaminated. 'I can't pretend it's not true. It's so obvious…! Khh…! I did a bad job protecting everyone. Switching with Akeno was the right choice. She'll be able to control Marcus better than me-"

"Marcus, why don't you escort Xenovia to the bathroom? She looks a little sick." Akeno asked.

"Heh?" Rias said.

"Huh?" Issei exclaimed.

"What?" Marcus asked.

"Yes, I'm very sick…!" Xenovia burst with adrenaline.

"I-I don't know the layout of the house too well yet. Maybe Kiba should-"

"Oh, my! No, you go. Be a good boyfriend and help poor Xenovia, okay? Take your time… There's no need to rush while you're there with her." Akeno's question was more akin to a hidden command. Between the overbearing smirk on her face and the mild sarcasm in her voice, she had full control of the passive large man.

"I… Okay…" Marcus nervously agreed.

"I-is it really okay?!" Xenovia looked at Rias, expecting an intervention.

Anyone with a functioning brain could tell what would happen the moment Xenovia found herself alone with Marcus, too passive to reject anyone.

"Oh, my! Why are you asking *her, Xenovia…?" Akeno cut in with unhidden frustration in her voice. "Marcus is *my* boyfriend. Shouldn't you ask me? And is it that weird if I have him escort my sick friend to the bathroom?"

Yes, it was weird.

What was Akeno doing?

Rias almost raised her voice to intervene, until she received a subtle stare from Akeno; One filled with threat.

'If I say anything, she'll reveal the truth to Issei…? Is that what she's saying to me with that gaze?!' Rias was shocked. 'Why is she doing this?! What's happening?!'

"Marcus, make sure to stay with her until you're sure she's all good, would you? Don't hurry her out of the bathroom. Take your time. We'll all be waiting here." Akeno maliciously smirked.

In the end, Rias did nothing. Xenovia left with Marcus, eyeing the enormous bulge in his pants without the slightest of subtleties. Her lip-licking, desperate gaze, neck-massaging, and heavy breathing exposed her intentions very, very clearly.

As soon as they were alone, she would force herself on Marcus and suck his balls dry with a level of despair befitting that of a withdrawing junkie.

Marcus was not only too timid to say no but dealt with a powerful curse of lust. If one seduced him enough, it was easy to make him lose control and turn into a sex-starved animal, even if he had been sated until then.

Akeno had essentially thrown Marcus to the wolves; To Xenovia. 'Didn't she promise to handle Marcus by herself?! Why did she do that?! She should be minimizing sexual contact with Marcus, not stimulating his urges… Especially with the rest of the peerage!'

"I'll go help too…" Koneko got up and-

"Oh, my! Two beautiful women alone with MY Marcus? I don't like that, Koneko." Akeno pressed Koneko back into the chair by the leg. "I'm very possessive."

"…Yes." Koneko gave up.

The small interaction lit a light in Rias' head.

Had Akeno acted on simple jealousy-driven impulsiveness…? 'She's getting back at me, Issei, and Marcus…? Is this a joke, Akeno?!'

There was no joke taking place.

Akeno's subtle, malicious smirk to Rias made that clear.

At that exact moment, Rias knew she had made a big mistake swapping. Not only was Akeno acting on toxic emotions, but her brain must have been influenced by the curse.

A single night with Marcus had affected her to the point of acting out against Rias and compromising the peerage.

What would happen with a few more nights?

'I can't go back…! I'd break Issei's heart if I did…! And now I have a lie to keep up…! Khhh…!' Rias felt cornered.

"President…" Issei whispered to her.

"H-hm…?"

"Wasn't Akeno going to handle Marcus by herself? Is it a good idea to let Marcus go with Xenovia…? Right now, she must be…"

…Nymphomaniacally sucking Marcus off, going out of her way to bully her own throat as aggressively as possible to satiate whatever itch she had developed from ingesting so much of his semen. By the end of morning, Xenovia would have taken in several new loads down her throat, which would further impact changes in her mind and body.

And she would probably cum a lot in the process, deriving great sexual ecstasy as spit dripped down her chin, tainting the area around her lips with cum and spit bubbles – plus, all the musk that would latch itself to her natural odor.

…Maybe she would suck on his heavy sack, munching on it like she did with her food…

…Marcus was hung and hard enough to handle bites without pain…

…Rias felt slightly jealous-

"S-she's being tactical!" Rias whispered back, cutting her own train of thought.

"What?"

"Y-you see… Marcus is a lot to handle… So, she's using Xenovia tactically to help her out…! Just until we find a cure. I-it's all good because any effects of the curse on her will be reversed too. D-don't sweat it!"

"Is that so…?"

"A-and don't talk to Akeno about it or question her, okay? This is very hard for her because she misses you a lot so… You have to hold strong! To encourage her to stay strong!"

"Ok. I got it." Issei believed in Rias.

Certainly more than herself.

…

'What happened last night?' Akeno asked herself, looking at the mirror in the school's bathroom.

She could not remember too well, having passed out immediately after beginning her second round with Marcus. 'I think I remember cumming a bunch of times... And moaning… And his dick pounding past my cervix like crazy… Other than that, it's just a blank.'

…

'But…'

…

'Did I do a good job…?' Akeno felt oddly insecure. A rare feeling for her, who oozed confidence.

Unlike Rias, she had offered herself whole and without hesitation to Marcus.

Why had he behaved that way during breakfast earlier?

…Looking at Rias…

…Missing her when Akeno was right there…

…Issei barely looked her way too…

…

'Am I second place again…? That's impossible. Yeah… It's just because he got used to her. Of course he prefers me. We just got together, but I'm giving myself whole. He HAS to prefer me.'

…

'Especially…' Her eyes moved to her chest in the mirror. '…With those huge tits… They grew a little bigger, didn't they…? I can tell. He's a big man with a big black cock and an insatiable sex drive. He has to prefer the woman with the bigger tits who doesn't hesitate to be a slut for him, doesn't he? Especially if her tits are going to become even bigger. Otherwise, what's the point of carrying this excessive weight on my front? It'll ruin my athleticism… Playing volleyball will go to hell… He HAS to prefer me…'

Has to.

HAS to.

…

'Hah… My head's a bit jumbled… Is this the power of his semen warping my mind? It feels a little good, though…' There was a CONSTANT ache between Akeno's legs. 'I want him to fuck me again…! I can tell that I'm more used to it already…! I wanna get blacked by his big black cock all night…!'

…

However, Akeno would not do anything reckless. 'He's satisfied enough after last night. I don't think he'll get cravings for a few days at least. Let's be responsible and not entice him, yes…? I did make a promise to Rias.'

Earlier, she fucked up with Xenovia, regretting it instantly afterward. 'I never felt so much anger in my life. My mind must have gotten at least a little warped. Oh, my, how silly of me! To feel jealousness? I am able to ignore my Fallen Angel heritage but not a bit of jealousy? That's just not me.'

Akeno smiled at her reflection.

"Oh, Akeno." Issei coincidentally ran into Akeno leaving the bathroom.

"Oh, my, Issei. How are you doing? I hope you didn't have too bad of a morning with the news." They walked together down the school's hallway.

"Ah… That's okay. I'm fine…"

"…Really? Aren't you desperately missing these…?" She brought an arm under her voluptuous chest and bounced it up and down. "Rias is pretty, but mine are bigger, right…? And they grew a little bigger from all the cock Marcus gave me last night."

"Heh heh heh heh…" Yes, Issei did miss her, but not just her breasts. He missed Akeno herself.

However, he had no intention of making the same mistake he did when Marcus was with Rias, especially after what he had been told earlier. 'I bet Akeno is worried that I can't handle her being with Marcus. She's worried about me, trying to figure out if I'm okay. I made everything a mess by being so disagreeable when Rias became Marcus' caretaker, but I'll do it differently now…! I don't want to add stress and pressure to Akeno! I know she's doing this to help us all return to a normal life, so I have to show her my strength!'

"Issei? What's that face…? Why do you look so serious all of a sudden…?"

"I am fine with Rias, Akeno."

"…Heh?"

"I understand you're just doing what you have to. I miss you, but I'll be happy with Rias alone for as long as needed. Don't worry about me. I won't get in your way! I'll cherish what I have, like you told me to!"

"Oh, my." Akeno silently stared at him with a growing smile. It seemed that his words were exactly what she wanted to hear. "Isn't that wonderful? When Rias became Marcus' big black cock cumhole, you were a big crybaby who could barely pay attention to the woman on your side. Now that it's me, you're a strong boy who can take it with no problem. I love seeing it. My tits are a little fuller and you don't even care! You're a big boy who doesn't need me, aren't you, Issei?" She gently pinched his cheek.

"Aaah, yes, yes…! I'm a big boy…! That hurts…!"

"Yes, it does, doesn't it…?" She pinched harder before resuming her stride. "By the way, have you seen Marcus anywhere?"

"Hm? Not really… Why?"

"No reason. I was just thinking of my duty."

"Your duty…?"

"Yes. I think I hate it. That makes me feel VERY impulsive."

"I get it…" Issei assumed her 'duty' meant milking Marcus.

"Oh, my. I don't think you do, Issei."

"Huh? Why not…?"

"Because you don't pay attention." She smiled the widest yet.

Akeno was in an excellent mood.

"I can't believe the nonsense you're telling me, Rias. If this is a prank, it's long past time you said so." Sona had yet to stop facepalming.

"I know I screwed up…! Help me, please…!"

"It's your duty as the High-Class Devil and master of your peerage to handle his curse. Instead, you let him run loose on your queen piece? Just so you could continue your pointless romance with your pawn? Did you hit your head?" Sona barely raised her voice or accelerated her speech – that made Rias feel even more judged, coldly scolded about her lack of emotional control. "If you wanted that, why didn't you just kill him when I said so? He was a stray devil. You had all the justification in the world."

"I couldn't do it…! It's my fault he's the Black King piece in the first place…!"

"I understand your position, but you're being irresponsible. Aren't you aware of the power of his semen? Did you actually think your queen would be able to handle him because she's strong-willed?"

"She CAN handle him! Just long enough for you to help me!"

"No, she can't. You're seriously underestimating the corruptive power of his semen. Before you know it, her mind and body are going to be sexually warped in ways you haven't even imagined yet. To think you'd sacrifice your biggest piece to him… At least send him on contracts with women that he could breed. That way, he'd be satiated."

"I can't let him go around hurting and knocking up girls! When he loses control, he can be… Animalistic."

"Better them than your peerage, Rias."

"Sona-"

"You don't realize how lucky you are that he's obedient and passive. If he were half as sexually aggressive as the average black male, your entire peerage would be interracial cumholes already. The Gremory family heir's peerage would be a harem for big black cock."

"Wh-where's that coming from? What do you mean 'as sexually aggressive as the average black male'?! How would you know something like that?"

"Because I am a woman with internet access, you idiot, and so are the female devils in my peerage. Marcus might be YOUR piece, but he's already affecting MY pieces. I haven't even let them interact with him, and I've already caught them watching and discussing interracial porn together multiple times. Do you know how much of a mess this is? What do you think happens if he cums inside them a single time? I'm fighting to not spend too much time watching black cock porn myself, and you come here to tell me you're throwing your responsibilities away to enjoy romance with a pawn?"

"C-can't you just not watch 'black cock porn'?!"

"Did you miss the part where I'm a woman? There are some things you don't come back from. I can't forget what I've seen, and I certainly can't stop touching myself to hardcore porn of large black men smashing small Asian girls against the bed with their fat black cocks. It is what it is, Rias." Sona's ability to speak calmly about something so vulgar gave her the absolute upper hand in the conversation. "The point here is that giving up control over your piece was a remarkably stupid thing to do, even for an emotional creature like you."

"I'm not emotional!"

"Please."

"It'll be fine…! Listen to me, Sona…!" Rias grabbed her shoulders and glared as hard as she could to convey her determination. "As long as we find a cure for the curse, everything will be fine! Help me!"

"Rias…" She removed Rias' hands. "…It's incurable and you know that."

"Maybe it isn't! We know so little about it. Maybe you can find something! You're smart and resourceful enough for that, aren't you? You're Heir to the Sitri clan!"

"Hah… That's pointless hopefulness. Rias, go back to acting as Marcus's full-time dick drainer. If you are able to keep your pieces clear of him for long enough, they might recover on their own-"

"Sona, please…!"

"…" Sona remained unconvinced; For better or worse, she was too calm and confident to be persuaded by Rias' emotional appeal.

So, Rias tried an appeal to reason. "Think about it! I-isn't it just a matter of time until he has sex with other devils and corrupts them? Wouldn't it be better for us to find a cure and fix it earlier rather than later?!"

"You're saying that it's inevitable that my pieces and I will breed with his big black cock eventually…? Hm… Interesting… Sex with him is inevitable… One way or another, he's going to shove it inside me and my pieces and pour gallons of semen into us while flexing his big muscles, huh…?"

Something in Sona's tone and word choice left Rias uneasy, but she powered through to keep her momentum going. "U-unless we find a cure! Please… I can't hurt Issei a second time… He was so happy last night…"

"You're being a coward."

"Yes, I'm begging you like a coward! Please!"

…

…

…

"Hah… No promises, but… I'll look into it and see what I can discover."

"Thank you! Thank you!" Rias broke into tears, hugging Sona.

"That aside, you should watch out for yourself."

"For myself…?"

"I said it already, didn't I? There are some things you don't come back from. In the West, they say that once you go black, you don't come back."

"What are you saying…?"

"I'm asking you if running all this risk is worth it. After having so much sexual interaction with a superior black male like Marcus, are you truly back with your pawn? Won't you be lusting for Marcus' big black cock soon enough, making all this pointless?"

Sona had always been perceptive at catching lies.

"I need to go…" That was why Rias did not answer.

"One thing, Rias. Don't let things spiral out of control, would you? Let's avoid causing a ruckus in the underworld that might bring intervention from other clans."

"Of course! I trust Akeno!"

"I hope you're right."

Rias had to hope a lot too to avoid panicking the instant she entered the Occult Research Club room.

"Oooh ! Nhgoh ! Uungh ! Too big… ! Uuuungh… ! Cummiiiing !" Akeno was bent over against the side of Rias' desk, getting RAILED from behind by a naked, aggressive, sweaty Marcus. "Oooooooh !"

Meanwhile, every other member of the peerage was present – except for Xenovia – sitting on the couches and chairs, uncomfortably waiting or averting their gazes – except for Koneko, whose eyes were so bloodshot that Rias could not look at her face without feeling creeped out.

PLOP! PLOP! PLOP! PLOP!

"Nghuuuuh ! Oooooh ! Mnghooooh !" Rias wanted to ask Akeno what was going on but could tell that she lacked the proper state of mind to answer any questions: Her usual smirk was absent, replaced by a dangling tongue and crossed eyes. Moreover, her uniform had become glued to her fleshy figure due to excessive sweat pouring from her body, along with generous volumes of sex juices gushing from between her legs.

Just like in the bedroom last night, it was a mad show of vulgarity that intensely captured Rias' attention. 'Woah …' She had trouble looking away from Marcus' GIRTHY, VEINY black cock pulling all the way out of Akeno's hole only to SLAM back in at full force, making her thick rear ripple with the vicious impact, almost sending her toppling forward against the desk if not for his dominant grip on her ponytail.

Marcus could be quite dominant whenever he was overwhelmed by the curse's cravings. Rias found it quite alluring to stare at his sweaty, pumped, veins-clad muscles destroying Akeno's plump rear with animalistic rams…

'Ah, what am I doing watching?! But… It's not like I can do anything…! Shouldn't he be satisfied after having sex with Akeno all night? Did he really have an episode now…?! Did something happen?!'

All important questions.

"Mnghoooh ! Hoooh ! Uuuungh !" None of which could be answered with Akeno wailing so loudly from pleasure and physical strain taking hold of her thick body. Even though Akeno was an athletic woman, she seemed to be on the verge of physical collapse. Staying bent over on her tiptoes while a girthy, long, HARD cock bulged her flat stomach and repeatedly churned her insides had to be immeasurably difficult.

Rias would know.

…She remembered the pleasure well…

Though, once more, seeing it was far different from feeling it. Rias was fascinated by the way Akeno's pussy lips twitched; The sounds of the squelching caused by the hard member scraping her wet pussy walls; The protrusion making itself known through the midsection of her uniform; The juices flowing down her inner legs; The wet clapping sound caused by Marcus' muscular front CRASHING against Akeno's meaty ass; The way her breasts swayed back and forth even inside her clothing; The expression of bliss on her red face, having trouble breathing from agitation alone.

And…

"Oooooh ! Nghoooh ! Mnghooooh !" …The moans.

'I wanna feel that way too- What the hell am I thinking?!' Rias interrupted dangerous intrusive thoughts trying to dominate her head.

Was it the Black King curse? Had she been affected too, even if minimally? Or was it just her urges as a normal woman?

…Which answer morally justified her vagina throbbing just from staring…?

"President…" Issei noticed Rias.

PLAP! PLAP! PLAP! PLAP!

"H-hey." She sat beside him. "What happened?" It was difficult to hear her own voice due to the constant sounds of hardcore sex.

"Mnghooooh ! Hooooh ! Nghuuuuh !"

"I don't know… Everything was fine… Then Akeno spoke to Marcus a little and announced she would have to milk him right here because he was having an episode…" Issie was visibly uncomfortable.

PLOP! PLOP! PLOP! PLOP!

"I-is that so…" Rias grabbed Issei's hand, squeezed it, and decided to wait it out. What else was she supposed to do? 'I still don't know what's going on with Akeno, so it seems like a bad idea to intervene…' She told herself…

…While her eyes focused on the THICK cock POUNDING Akeno's uterus with FURIOUS thrusts. The sight of Marcus' large torso towering over Akeno with his fists resting on the desk was amazingly enticing. 'He's so masculine … Akeno is a tall girl, I'd say… And he completely shadows her… Look at her face and all the juice coming… Ah… I bet her uterus is getting hit so hard by that hot tip of his…'

It could have been her.

At that very moment, Rias could have been the one bent over against the desk, getting her ass pounded so hard it momentarily turned flat with each collision.

"Uuuungh ! Mnghhhh ! Cummiiiiiing ! Ooooooh !" …It could have been her cumming cross-eyed and breathless.

…

Was Akeno not having a bit too much trouble handling Marcus?

She was not a High-Class Devil. Maybe she needed assistance.

Maybe it would be a good idea to assist-

Rias glanced at Koneko by accident.

That single stare ceased every thought in her head.

'Am I staring at Marcus the same way she is…? Like a… Perverted creep…? I need to control myself.'

Koneko was starting to SERIOUSLY worry Rias. The dryness of her bloodshot eyes could not be comfortable, but she still refused to blink, obsessed with catching every millisecond of the rough sexual act taking place.

'Does she even care about the sex? I feel like she's always staring at him. Maybe she just wants to look at him naked…? Smell him…? What's going on in her head…? And… Hasn't she been quieter than usual…? It's like she's avoiding speaking for some reason…'

In the end, Rias controlled herself and avoided looking at Akeno and Marcus. 'I can't deny my urges as a woman. He's got a huge cock, big muscles, and knows how to fuck hard. Sorry, Issei… I still love you, but if I look at him, I start getting horny and comparing… And… Sorry, Akeno. I'll just leave you to it without helping. It was your choice, so you don't mind it, right…? I think you want this…'

"Cummiiiiing ! Uuuuungh ! Nghoooooh !" Indeed, it seemed like Akeno did not mind it.

PLOP! PLOP! PLOP!

"Ooooooh ! Fuuuuck… ! It's so big… !" Even if she was breathless and barely able to remain in place, Marcus did not require too much conscious input from her to successfully milk himself dry into her pussy.

PLOP! PLOP! PLOP!

"Hoooooh ! Uuuuungh ! Mnghuuuuh !" With her figure, Akeno would do just fine by remaining alive and taking it. Her role was simply to exist and stay in place as the giant black man wrecked her pussy like a mindless savage, mounted on top of her with his fists on the desk. Her ability to not fall forward even in that frenzy was commendable.

PLOP! PLOP! PLOP!

"Nghooooh ! Mnghhhh ! Uuuuughn !" Though, even if she fell, would it make a difference?

Marcus was a virile black male who needed to dump massive volumes of semen to be healthy. If Akeno fell, he would just follow her down to destroy her pussy and uterus in whatever position she was in.

…His big black cock would find its release in a tight, soaked pussy one way or another, sending his target into a heaven of frenzied, wet sexual ecstasy…

PLOP! PLOP! PLOP!

"Ooooooh ! Nghhhh ! Mnghhhh !" Akeno did not need any help. She was just fine getting her narrow insides stretched out by a cock so girthy that the concept of squeezing felt comically irrelevant; His girth alone resulted in vaginal prying to Akeno's limits.

'Maybe I should call off today's meeting… I figured we could talk about how Akeno will be taking care of Marcus from now on, but breakfast solved that, so…'

Just as Rias intended to dismiss everyone so they did not feel compelled to watch the sexual spectacle taking place, she found herself mesmerized by Akeno's face.

She was grinning at her; Bragging.

As playful as Akeno was, she had never looked at Rias with that level of malice before.

The curse was getting to her.

'I made a serious mistake underestimating how quickly she'd get affected…!' Akeno might have had some form of jealousy deep in her heart before, but getting her uterus tainted by Marcus' semen was corrupting and warping her mind far too intensely. 'I can't go back to Marcus now… I'll just have to do my best to not antagonize Akeno until Sona comes through. That way, she probably won't do anything too impulsive…'

What if Sona never came through?

'…' Rias utterly rejected that outcome, afraid.

Everything would be okay. How hard would it be for Rias to avoid antagonizing Akeno?

'Not hard at all.' Rias knew that for a fact.

But what if someone else antagonized Akeno?

"Nghhhhhh ! It's pulsating… ! Oooooh… ! Are you gonna cum, Marcus? Yeees... ! Blast my slutty little hole with your wonderful black cum… !"

"Yes…!" Marcus tensed his body so strongly that dense veins bulged throughout his entire body, especially his closed fists on the desk. "Master…! Khhh…!" He growled with his eyes shut.

…

'Master?' Rias blushed; Her vaginal lips throbbed.

Even while cumming hard inside another woman, Marcus was thinking of shoving his big black cock inside her.

Akeno must have thought the exact same thing, feeling an emotion so strong that bliss disappeared from her face, replaced by an emotionless glare toward her and Issei that only lasted for a split second, quickly replaced by a wide, wide smile.

"Koneko." Akeno said with remarkable composure, considering how disordered she looked just a moment ago; Even now, her entire figure trembled. "Come here."

"…Huh?" Koneko finally blinked, shocked. "…Really?"

"Yes. Now. Get here, quickly." Akeno pointed to the floor between her legs.

Before Rias could say anything, Koneko had already rushed to her knees in front of Akeno's legs. Her back was tightly pressed to the desk, having almost no room to fit where she was.

"Ghhh…! Cumming…! Khhhh!!!" Marcus let out one last DEEP grunt, accompanied by aggressive contraction of his abdominal muscles. His balls shuddered from how much cum was about to burst from his urethra.

The target would not be Akeno's womb, though.

"Nghhh !" After all, she pulled out at the last second, catching everyone by surprise.

"Ah …" Especially Koneko. She was the most surprised of all when the heavy, flailing, monster black cock fell straight on her face. She quickly grabbed it and-

"No touching!" Akeno slapped Koneko's hand away and took control of the penis herself by grabbing the shaft. "Just stay there."

And then, a shower of viscous, rich cum.

Everyone watched it with some variation of amazement in their eyes.

The sweaty, exhausted Akeno used both hands to control the swinging of Marcus' big black cock, keeping its tip aimed at Koneko from a small distance. She gently stepped on his toes to force him to step back, thus making it possible for the penis to aim anywhere on Koneko's body.

That she did. Koneko was showered from head to toe. Akeno made sure to move his cock after each voluminous jet to ensure no area of her body remained untainted.

Face; Hair; Chest; Midsection; Upper legs; Crotch; Shoulders; Arms; Forearms; Hands.

…Cat ears and tail, which came out at random amidst the cum shower. Koneko was not entirely comfortable with her special genes, often keeping her cat ears and tail concealed via magic.

…Why had they come out…?

Akeno treated Marcus' penis like a hose and Koneko like her garden. Every inch had to be watered with semen, and Marcus had more than enough volume and masculinity to fully bathe the petite girl's skin.

Once it was clear that no part of Koneko's body had been left untouched, Akeno let go of Marcus' penis and restrained it between her thick inner thighs, with her back facing him – the same form of thighjob position that Rias found herself in a few days ago with Marcus, in that same room, in front of the same people.

She looked at Rias, grinned, and let the cock swing wild and free within the limited space of her thick legs' restraint. Marcus' release was long enough for all that. Every cumshot was equivalent to a dozen from Issei, if not more.

'Ah… There I go again, comparing Issei to him…'

…

'But how wouldn't I…?' Rias obsessively observed the swinging cock; The puckering of the urethra; The popping of more and more veins; The endless shooting of cum on Koneko.

It was a majestic sight.

No wonder it was the Black 'King' piece.

…The king of masculinity…

"Ooooooh… !" …And the king of making women feel like women, as shown by Akeno's quick return to orgasmic form, trembling as the cock's shaft smacked her pussy lips again and again as it maniacally swung up and down. On instinct alone, he grabbed Akeno's breasts by sinking his fingers through her uniform, making her grit from painful pleasure. Even with no cock inside her, she felt enough ecstasy to squirt all over his penis, adding more sticky sex juices to it. "Yes… ! Use my big tits… ! That's what they exist for… ! They need to have a purpose… ! Grab hard… !"

About two minutes later, it was over. Marcus was no longer pumping cum, though his penis continued to pulsate and swing slightly. "Hah… Hah… Hah…" He let go of Akeno and stood up straight, catching his breath. His shredded, muscular physique was clad in veins and sweat.

"Hah … Hah … Hah …" Akeno was no different, still shivering from lingering and delayed orgasms. Every few seconds, small gushes of pussy juice came out of her twitching pussy lips. Her calves looked strained to the limit from keeping herself on tiptoes to properly thighjob Marcus – he was that much taller than her, with a cock so hard that her inner thighs seemed slightly burned from the friction of the frantic release.

And Koneko…

"…" …Was doing nothing but breathing VERY intensely. Slowly, but intensely.

…And quivering slightly…

At first, Rias saw that as a positive thing. 'Her skin is completely covered in sperm, but she's not doing anything. M-maybe she's not that affected-'

"Ghn ." Koneko let out a small grunt.

…Followed by an ERUPTION of pussy juices from under her skirt.

Not just any eruption; A CATACLYSMIC one that loudly hit the floor with so much liquid that the puddle grew and grew, trailing all the way to the couches and chairs that everyone was sitting on.

Rias looked at the expanding ocean with a slacked jaw. 'I could pour a full water bottle on the floor and it would be less than this…! This is all from having her skin covered in semen?! H-how hard is she orgasming?!' She looked at Koneko again.

At first sight, it seemed impossible to tell. Koneko was not shaking all that much; At least not enough to match the ocean of female sex juices ruining the floor of the clubroom. Or was she cumming so hard that shaking was impossible due to excessive tension throughout her body?

However, even if at first it was not clear, the answer soon became obvious by focusing on her cat tail instead.

It danced, flailed, and swayed around in a frenzy of joy.

Koneko was climaxing very, very intensely.

"K-Koneko, are you okay?! I'm so sorry! I-I don't know why Ms. Akeno did that…!" Marcus squatted to check on Koneko, but there was no reaction even after shaking her. Koneko had turned into a kneeling statue covered in cum.

"Uuungh …" Akeno groaned weakly before collapsing forward, landing face-first on the desk. Whatever energy or malice existed in her a minute ago had fully expired, now replaced by absolute physical fatigue. "Ghnnn …" Based on the continuous twitching of her vaginal folds and continuous production of sweat, she was still orgasming.

"Ms. Akeno?! Are you okay?! Ah, I hurt them both…! I'm so sorry…! This is all because of me…!"

"Marcus." Rias called out. "It's okay. Just… Uh… Dress up and help Akeno to a seat, okay? Everyone understands what's happening and it's not your fault. Don't feel bad. It's not your fault if your penis and body are so strong that she's tired afterward. Sh-she's your dear girlfriend, isn't she? So she knows what she's doing. I'll just make a few quick announcements and then we're all dismissed. You can take her to the infirmary then, if she needs it."

"O-okay…! Sorry, sorry…! Why do I have this body…?! I hate this…!" Marcus continued to mumble under his breath as he dressed up and carried Akeno to the couch, sitting beside her. His uniform soon got ruined with sweat stains and sex juices, much like Akeno's.

"Ughnn …" Akeno rested her face against his shoulder, opening her eyes. Though tired, she was conscious.

Rias got up and moved in front of the desk to speak to everyone. 'How can I pretend everything is well after all that? This room smells of sex, and I'm stepping on Koneko's sex j- She's still there?!' She realized Koneko had not yet gotten up. "Koneko. Go back to your seat, please…"

…

"Koneko…?" Rias squatted in front of her, maintaining distance to not touch the semen plastered all over her. 'W-woah…' She was taken aback by Koneko's expression. 'She's crying like crazy and smiling so much… One of her eyes is rolled up and twitching too… Th-this is a little creepy… Are her cat ears twitching…?'

"…"

"Can someone hand me a towel to clean-"

"Don't clean me up, thank you…" Koneko got up and moved to her chair perfectly normally – which meant shivering nonstop and breathing heavily, along with continuous sexual fluids streaming down her thin legs and soggy skirt.

Everyone looked at her, amazed by her euphoric expression and the INTENSE reek of sex emanating from her cum-bathed body.

"Okay, everyone. Let's get on with it!" Rias snapped her fingers, hoping to bring order back. "I wanted to announce that we've finally sorted out the funds with the Student Council, so we'll get to go on the trip to the cosplay and anime event in the coming weeks-"

"Shorry for being late." Xenovia barged into the room, carrying a box of hot dogs, one of which was currently inside her mouth… And deep down her throat, seemingly unchewed as it bulged from her neck. Her uniform seemed stretched to the very limit of what it could without bordering on weird. If Xenovia gained slightly more breast size or muscle mass, her clothes might tear off with the most normal of movements.

…

'Oh, no.' Rias looked at Koneko covered in cum and then back at Xenovia.

She knew what was about to happen.

Sadly, that did not help her in knowing what to do next.

"H-hoh …" Xenovia dropped the box of hot dogs and rushed to sit beside Koneko, moving Kiba out of the way. "Koneko…" She glared at Koneko with the same intensity that Koneko glared at Marcus earlier.

Koneko glared back, trying to intimidate Xenovia who had gotten far, far too close to her. Their faces and bodies were so close together that if either one moved an inch, they would be touching.

"Hah … Hah … Hah …" Xenovia breathed heavily, panting with her tongue out of her mouth as her chest heaved intensely. Sweat ran down her forehead as agitation installed itself in her mind.

It was like watching a starving animal being offered food.

…Xenovia wanted to eat – or in this case, drink…

"Don't touch me." …And Koneko wanted to keep her second layer of skin untouched, supposedly enjoying the feeling of Marcus' creamy sexual fluids on herself.

The atmosphere quickly grew tense, and it only got worse as Rias took note of an unexpected change in Xenovia's face: Her lips were fuller. Not enough to look like surgery had been done, but more than enough to call attention.

…Her body was changing…

"Koneko, you're really dirty. Let me shower you, okay? Okay… ?" Xenovia moved closer slowly.

"If you touch me, I will kill you." Koneko stood her ground.

"Why, why? Don't cats like grooming? Let me groom you …" Spit dripped down Xenovia's dangling tongue at an unusually fast pace.

"Don't touch me…" Koneko frowned harder.

Rias approached them, leaned forward, and authoritatively stared at Xenovia. "Stop."

…

"Yes…" Xenovia backed off.

…Side-glancing with continuous drool dripping on her clothes, licking her lips without pause.

Rias still had authority, but things might have been slowly spiraling out of control.

'It's gonna be fine…! It's gonna be fine!' Rias thought.

…Trying her best to ignore noticing Akeno's smirk toward her.

Everyone had already left the clubroom. Rias quickly talked to Issei to make sure he did not become suspicious about Akeno's behavior. 'He says he trusts me and is going to patiently wait it out until Marcus is cured. Crap, he really bought into my lie… He must be really hopeful that things will go back to normal. Me, Akeno, and him together… And that silly fantasy of him of being a Harem King Devil… I need to hold on too…! Don't piss Akeno off until Sona has a solution!'

Rias had stayed behind to find some papers that the Student Council demanded about the budget of their club. Once she was done, she would meet Issei outside and they would go home together.

That task was easy enough, taking her less than two minutes.

The problem was leaving the room.

Rias was finding it quite difficult to stop looking at the puddle of cum on the floor, where Koneko was kneeling a few minutes ago.

No one was available to clean the room. Koneko and Xenovia had their own 'problems', Asia was too innocent for it, Issei and Rias had a date, Akeno was exhausted, Marcus was too pitiful, and it would be cruel to make Kiba do it alone.

So, it was left for tomorrow.

…Meaning that Rias had been left alone with a puddle of rich cum to stare at.

Why was she staring at it so much?

Rias was fixated on the beautiful, creamy texture.

Her lips salivated.

Her groin ached.

Her heart raced.

And her nipples were unspeakably erect, chafing hard against her bra.

'I'm really interested in it, aren't I…?' Rias prided herself in self-awareness. 'I'm interested in cum on the floor…? This can't be just my base interest as a woman, right…? Just because it's the seed of a hypermasculine male and tastes really good… And is nice to chew on and swallow… There's no way I'd like just as a woman. I must be a little corrupted. That would explain everything. Marcus did cum a lot on my hands, boobs, in my throat, and in my vagina. Yeah… Yeah. That's all. That's why I'm fascinated by this delicious puddle… Isn't it beautiful…? From this close, I could lick it… I bet Xenovia would have if she hadn't been so fixated on Koneko…' Without realizing it, Rias had gotten on her knees and brought her face a single inch away from the fluids.

The odor was wonderful.

No wonder Koneko was so hooked on Marcus. She had stronger senses than the others, meaning her nostrils must have become obsessed with sniffing the masculine scent – especially now that she had received so much direct contact with his seed.

…

'Even if I'm a little affected… I'm going to be just fine after we cure Marcus, right…?'

…

'So, it's not that big of a problem if I act a little reckless and indulge myself, right…?'

…

'It's not like… I can control myself… If I got a little corrupted… Right…?'

Rias breathed heavily.

"Ngh …" …And rubbed her now-bare nipples.

"Oh, finally. It was taking you a while." Issei almost entered the clubroom to see what was taking Rias so long.

"Ah, my bad. I had trouble finding these!" She showed him the papers. "Let's just drop these by the Student Council room and go home."

"Okay." Issei was in a good mood, all things considered. Knowing they would cure Marcus and everything would go back to normal allowed him to fight back against the urge to snap in anger over everything going on.

That said, one thing did make him uncomfortable. "What happened to your uniform?" He asked Rias.

"H-hm?"

"Your chest." Issei pointed. The chest area of Rias' uniform was soggy, as if she had dropped a full glass of water on it – the nipples, in particular, seemed the wettest. 'Why does the smudge look so sticky too…? And kinda smelly…'

"Ah, it's just… Sweat! Hahahah…" Rias looked away and blushed.

"Huh. Alright." Issei loved how cute and prude she was at times.

Two days passed since the 'incident' at the clubroom. Since then, nothing TOO weird had happened, barring Akeno's constant flirting with Marcus, Koneko's bizarre glaring, and Xenovia's 'obsessive' eating and drinking habits. 'I wish Akeno didn't hit on Marcus so much in front of everyone, but… She's just being his "girlfriend" until Rias comes through with that cure… She never tells me the details when I ask, though…'

…

'Well… There are a couple of weird things going on, but… It's kind of inevitable I guess…'

Namely, Akeno and Xenovia were forced to make changes to their uniform due to the growth of their bodies.

Akeno had grown a couple of inches in terms of height, but that was nothing compared to the significant addition of fat to her hips and breasts. Because her uniform no longer fit her properly, she had to crop her dress shirt and skirt. 'Seeing her navel out is sexy, but it makes me jealous too… Ghhh… If only it didn't mean that she's having a lot of sex with another person…! Dammit…'

Xenovia changed as well, though her case was different from Akeno's. She did not grow in pure meatiness, which was Akeno's situation. Instead, Xenovia's growth was very muscle-related, with her thighs and ass expanding the most of all, sporting thick veins due to substantial leanness and muscle mass. Furthermore, she had grown more than Akeno in height, now as tall as her despite starting at a lower point. Akeno had gone from 5'7 to 5'9; Xenovia from 5'5 to 5'9. Still, her breasts did expand a full cup size as well. Much like Akeno, Xenovia cropped her dress shirt and skirt, leaving a full set of abs in plain view all day.

Regardless, muscle mass was not the creepiest part of Xenovia's changes; That would have to be her lips, which grew softer and thicker after the incident in the clubroom. Issei's friends asked him multiple times if Xenovia had done some sort of light surgery to her mouth – a rumor that soon spread throughout the school, along with the news that Akeno and Marcus were now boyfriend and girlfriend. The changes to her outfit had been attributed to 'black men liking it better that way'. In the public eye, Akeno was a slut for Marcus – a perception that infuriated Issei, whose relationship with her had never gone fully public before.

Right now, issei was enduring a boring class by hiding behind Marcus' wide back. 'This guy is so big that the teacher can't see me. I hate him… He looks so funny sitting on that tiny chair... That's just how big he is.'

Out of boredom, Issei found himself glancing to the sides every so often. 'The girls are always looking at him. If this guy were a bit more confident, he'd be sleeping with every girl in this place. He'd have a whole harem… He's basically getting one already by doing nothing but being a big guy with a huge dick. So unfair…'

…

'No, I'm gonna be the Harem King! Don't give it up, Issei! This is all temporary! Don't think about it! Akeno's coming back and we're going from there!'

…

Class ended. With no plans, Issei intended to invite Kiba to eat something at the cafet-

"Hey, Issei." Marcus turned around – almost breaking the chair's back – and talked to him.

"Oh. Hey."

"H-how are you…?"

"I'm fine, how are you?"

"I'm… Uh… I am…" She rubbed his forehead and then his chin. "Good." Marcus had forgotten the proper Japanese wording, so he spoke in English.

"Ah. Good."

"Heheh." He laughed nervously.

…

And then awkward silence.

…

"Anyway, I-"

"H-how's Rias…? I mean, Master..."

"President's fine…"

"Ah, President! You call her 'president'. President."

"Presidant."

"No, no, President.'

"President."

"Yes!" Marcus raised his fists, celebrating Issei's pronunciation.

'…What is this conversation?' Issei wanted to get out of there.

He understood Marcus' discomfort and lack of choice in the grand scheme of things. Moreover, he understood that he was a foreign student who had trouble fitting in – especially because of his VERY different physical structure and skin color, AND imperfect Japanese.

'…But I don't sympathize or pity him at all.' Issei could not care about him. On an emotional level, he would always have disdain for Marcus, even if he externally acted nice. How could he possibly like him after everything he saw Rias and him do? 'She gave him boobjobs and rimjobs… Ghh… And he fucked her like crazy in the gym's equipment room. I can't just forget that. The stuff she said to him… I haven't confronted her about it, and don't even know if I should, but I can't avoid feeling jealous… And…'

…And he could not forget the faces and sounds made by Rias as Marcus RAVAGED her in a ruthless Nelson hold. 'I never make President cum more than once or twice. He made her cum so hard that she was barely awake by the time he shot his first load. "First load". This guy shoots multiple ones, and I precociously shoot only once… Crap…'

Issei felt inadequate. It was hard to see himself as a man worthy of Rias after everything he witnessed. 'We haven't had sex even once after we got back together… I don't think I can do it… She's not going to cum as much with me… There's not going to be any bulge in her stomach because my dick isn't that long or thick… The moaning is going to be so much weaker… What if she doesn't even make any faces? I can't believe I'm this way. Is the same thing going to happen when Akeno comes back? What do I do…?'

"So, President is okay…?"

"Yes."

"That's good, that's good…" He looked away, gloomy.

Marcus clearly missed Rias. 'I guess he fell in love with her. That's easy to understand… President is amazing.'

…

"Uh… How's Akeno?" Issei took the lead this time.

"Ah, Ms. Akeno is great! She's… She's good."

"Cool…"

…

'Holy fuck, this is awkward!!!' Issei wished to die.

"Ms. Akeno… Is a little scary." Marcus said.

"Ah… I think I know what you mean…"

"She sometimes… Is very bossy and… Uhm… What's the word…"

"Teasing?"

"Yes!"

"Yeah, that's her. And she's always saying 'Oh, my' to laugh in your face."

"Yes! Oh, my. Oh, my."

"Oh, my."

"Oh, my. Oh, and she also…" All of a sudden, the two bonded slightly over Akeno's overbearing nature.

In some way, Marcus was alright.

'…But he's still fucking the shit out of Akeno with his stupidly huge dick…' It never took long for Issei to dwell in negativity. 'Grr…'

"Ah… I got a text from Ms. Akeno." Marcus sighed. "…I need to go…"

"…" Issei said nothing to keep frustration from poisoning his voice. 'Is he telling me that he's about to go fuck her? Grr… Don't say anything…! I need to calm down…!'

"…" Marcus did not get up. For the longest time, he remained in place, saying nothing. The gloom on his face became more prevalent. "You know… I think Ms. Akeno doesn't really care about m-"

"I don't wanna know." Issei cut in.

"…Sorry." Marcus got up and walked away.

'Tch… I can't control myself THAT much, sorry… I wonder if he thinks Akeno actually loves him. President didn't tell me if Marcus knows that Akeno is just taking care of him so she can sort out the cure thing… Better not to bring it up in that case. What was he going to say, though? Ah, who cares? I'm just pissed now…! While I'm here, doing nothing, Akeno is going to be getting railed by that guy's huge dick?! How am I ever going to have sex with her or President again if they get used to that sort of sex?!'

Issei mulled over it for a minute before storming off the classroom to distract himself by looking out the hallway's window.

There, he saw where Marcus was headed: the gym. 'They're gonna do it in the equipment room? Where Akeno and I saw President? What's with that? Was it her choice? She's the one who texted him, right?'

…

'Wait, why did SHE text him? If Marcus isn't having any cravings, isn't he fine? Is she… Doing it preemptively…? But why would she choose there…? Is there a special reason? Couldn't she just do it at night, in their bedroom?'

Right then, issei realized something: He had received a text from Akeno several minutes ago but forgot to check it.

The content of the text puzzled him greatly: Akeno invited him to come talk to her in the gym's equipment room because she had a surprise for him.

'…Huh?' Issei failed to understand. 'But she also invited Marcus a few minutes after me? What's the surprise? I don't get it. Either way, I didn't get back to her in time. There's no way I'm going there now if they're about to do it.'

Just as he intended to walk around school to find Rias to hang out with, Issei noticed one more thing: Kiba following Marcus from a distance.

THAT made him very, very curious. 'What's he doing…?'

Issei followed Kiba.

'Th-this is a joke, right…?' Issei could not believe what he witnessed upon peeking over the corner of the gym. 'Kiba, what the hell…?'

Kiba was peeking into the equipment room with a hand inside his pants.

A very frantic-moving hand.

'He's jacking off to whatever they're doing in there?! Are you kidding me?! He can't be affected by the curse, so it's just who he is?! You like that stuff, Kiba?!' Issei half-regretted discovering that about the peerage's Knight. 'Ghh… This is too weird for me to get involved with… I'm getting out of h-'

"Issei, what are we doing?"

"AH!" Issei jumped in place, surprised.

"Eeeh?! What?! Did something happen?!" Asia jumped in place too. "G-g-get behind me…! I'll protect you-"

"What are you doing here, Asia?!"

"Heh? What do you mean?! I was walking beside you all this time!"

"Y-you were?!"

"W-well, maybe you didn't notice me because I was a little bit away, but…"

"…So you were following me."

"Yes! Because I don't know what's going on! I'm scared! No one is telling me anything… Akeno is with Marcus out of nowhere, Rias is back with you, Xenovia is acting weird, Koneko has been even quieter than usual… The only one who's normal is Kiba!"

"Oh... Yeah, totally..." Issei peeked out the corner to see if the 'normal' Kiba was still there. 'He left through another door. I guess he heard my yell. As long as he didn't see me, it's fine, I guess.'

"L-look, I know Akeno and Marcus said they're in love and dating but isn't it a little weird?! I don't know! And isn't Akeno in danger from the curse?! That's what Rias said the other time! Something is wrong, don't you think so, Issei?! We're both out of the loop, so shouldn't we stick together and figure it out?!"

"Y-yeah…" Issei felt bad for Asia. '…I have no idea what to say.'

"For instance… I saw Akeno come here earlier, before I found you! Maybe something is going on in there!" Asia turned the corner and ran for the equipment room.

"H-h-hang on…!" Issei did not react quickly enough to stop her. "Hang on, Asia…!"

"Let's try to figure out what's going on together, Issei! Don't you want to know too?"

"That's…"

"Or… Do you know something and you're not telling me…?" Her cute, innocent look transitioned to a sad, lonely one.

'…I don't know if I can tell her anything…! I'm pretty sure it's all supposed to be a secret. Shit…' Issei was forced to play dumb, shaking his head.

"I know. I trust you, Issei! Let's look behind this door!" With unprecedented fire in her eyes, Asia opened the door slightly to peek in.

Right then, her drive and determination vanished.

It was only natural. Asia was far too innocent for the visuals present inside the equipment room.

"Mnghoooh ! Nghooh ! That's it… ! Cumming, cumming… ! Nghuuuuh !" …And the sounds.

Just like Issei suspected, Akeno and Marcus were engaging in rough, loud sex within the equipment room, just like Rias and Marcus a few days ago.

What Issei did NOT suspect was that they would be engaging in EXACTLY the same rough, loud sex as Rias and Marcus.

"Mnghuuuh ! It's deep… ! Deep… ! My pussy's burning up with pain… ! Oooooh… ! Keep it up… ! Full rhythm… ! Fuck my tight pussy blaaack… !" Akeno was getting VICIOUSLY speared in a restraining, ferocious Nelson hold, carried with her feet raised far above her head and her legs locked in place by Marcus' beefy arms under her kneepits.

'Th-this feels weird…!' Issei was not comfortable with the intense déjà vu hitting him. 'Wh-why is this so similar…?! She's even wearing bloomers and a white gym shirt, but… Those can't be Koneko's this time, right? They would never fit. She must be wearing her own clothes… And they're already torn anyway! Was it Marcus, or just her new body?!'

Did the similarities with the other day mean nothing?

Had Akeno chosen that specific place for a reason?

…Why had she invited Issei to come earlier for a 'surprise'…?

That aside, there were significant differences too.

Perhaps the most glaring one…

"Ooooh ! Use my tiiits ! Use my tits too ! I told you to use my tits too ! Don't just fuck my pussy nice and hard, use my tits too ! Uuuuungh !" …Was the fact that Akeno maintained unexpected control of herself during the act.

Marcus was not slamming into her as hard as he slammed into Rias that day, but it was still HARD. Her ample ass quaked with each crash, and her round, large tits bounced every time-

'Her TITS?!' Issei's eyes shot wide open. Akeno's boobs had become even bigger than he had realized with her clothes on; Enough so that he could tell with ease. 'Isn't she becoming way too meaty?! She's gonna have to change her entire wardrobe if she grows any more! Isn't this all too quick?!'

Quick or not, what did it matter? Issie could do nothing to stop a thing. His only task was to hold on until Rias came through with the cure.

That did not make it any easier to bear the hideous sight before him.

PLAP! PLAP! PLAP! PLAP!

"Uuuungh ! Cumming, cummiiiing ! Why aren't you using my tiiiiits ?! I told you to use theeem !"

"I can't…! Khhh…! It's not easy to touch your boobs in this position, Ms. Akeno…! If we switch to another, I can-"

"Master! Call me Master!"

"Y-yes, Master…! It's not easy…! If I move my arms, I won't keep you in place properly-"

"You're just holding out on me…! Aren't you…?! I'm not good enough for you, is that it…?" Akeno's voice had a sharp change in tone; Somehow, she sounded perfectly collected despite Marcus' continuous thrusts, which were powerful enough to paint the background of their conversation with repeated wet clapping.

Her tone was not just perfectly collected, but also menacing, much like her wide-eyed gaze. Though she could not turn her face to make eye contact with Marcus, her voice conveyed authority.

"I-I didn't say that-"

"Use my tits… ! Uuungh ! Use my fucking tits already… !" Akeno insisted on the same thing, powering through the orgasms making her body shake.

"Khh…! Yes…!" Marcus relinquished proper control of one of her legs to 'use' her tits.

Until that moment, Issei was not sure what 'use' meant.

SMACK!

"UUUUNGH ! Ooooh, that was good… !" Akeno spasmed intensely upon receiving a HARSH strike to her breasts; One that left Marcus' palm indented on her skin. "More, more… !"

SMACK! SMACK! SMACK! SMACK!

"Mnghhhhh ! Oooooh ! Uuuuuungh !" Akeno wailed and howled frenziedly, trembling ceaselessly as each slap resulted in squirt gushing out of her black cock-packed pussy.

'This is so weird…' Issei had trouble seeing Akeno acting so off-character. She was a woman that rarely lost her cool, always smiling and teasing; Seeing her moan and beg for abuse like a mindless slut was abominable.

Yet, right now, she WAS nothing more than a mindless slut addicted to orgasming.

SMACK! SMACK! SMACK! SMACK!

"Nghhhhhh ! Hoooooh ! Mnghuuuuh !" Worse yet: Orgasming to supposed masochistic pleasure. Issei had no idea that Akeno felt any sort of desire to have her tits so aggressively struck. Marcus was sinking his palms so strongly and thoroughly that it would soon be difficult to find unmarked flesh on her chest.

Should she not have been in excruciating pain?

"H-how awful… That's awful…" Asia thought similarly to Issei, protecting her chest with her arms. Merely from looking, she felt afraid of whatever pain Akeno must have been feeling.

It genuinely made no sense. Akeno was not a masochist.

'Then… Is it the curse corrupting her…?' Issei theorized.

"Haah … Haah … Haah …" Akeno gasped for air once Marcus finally stopped abusing her breasts. "That hurt … That hurt so much … Uuungh …"

"I-I'm sorry…! I won't do it again…!"

"What the fuck are you apologizing for…? That wasn't enough…! Marcus, don't you like me…?" Akeno's tone became cold again. "When you fuck Rias, you go berserk. Why doesn't that happen with me…? Are you not into me…? Am I not good enough for you…? Are my big tits that worthless…?"

"N-no, that's not-"

"Hey… My tits are getting a lot bigger, aren't they…? Don't you think so…? It kind of hurts my lower back, and I feel a little gross, but I don't mind it because we're together in this, right? You MUST like HUGE tits, just as I like your HUGE cock and muscles, right?"

"I-I…"

"Or are you telling me that my huge tits mean nothing to you…? Are they becoming this big and annoying for nothing…? Am I not good enough for you even with bigger tits…?"

"Ms. Akeno, I…"

"Master! Call me Master! And why did you stop fucking me?! Why isn't that dick moving?! Why aren't you fucking me raw properly?! You didn't hold back for Rias, so why are you holding back for me?! You're THROBBING, so why aren't you MAULING the shit out of me?! Oh, my, I AM not good enough for, aren't I?!"

"I-it's just not so easy for me to-"

"Marcus, you better start showing me some gratitude for giving myself whole to you. If I feel like you aren't cherishing me, I might just throw you to *them*."

"…! I-I'll do my best…! I'm sorry!" Marcus gulped down nervously.

'Them…? Is she talking about Koneko and Xenovia…?' Issei was puzzled by the dynamic between Marcus and Akeno.

"Then, start cherishing me by making proper use of my FAT tits and fucking me as HARD as you fucked Rias! At the same time!"

"C-can't we switch positions-"

"In THIS one! I want THIS one!"

"Khhh… O-okay…! Master…!" Marcus gritted his teeth and…

PLAP! PLAP! PLAP! PLAP!

"Mnghuuuuh ! Oooooh ! Hoooooh !" …Resumed pounding Akeno in the rough Nelson hold.

SMACK! SMACK! SMACK! SMACK!

"UUUUUNGH ! Mnghuuuh ! Oooooooh !" Without a doubt, Akeno's greatest moments of pleasure came from the abuse of her breasts.

Nevertheless, the intense ecstasy of having her pussy stimulated and stretched by Marcus' big black cock could not be underestimated. 'I-it's twitching like crazy…!' Issei could not take his eyes off how much they quivered as the girthy, veiny member scraped in and out of her, protruding her flat stomach with its immense size.

Had Marcus finally managed to reach Akeno's demands?

"Harder ! Hit harder ! Hit more ! Don't lose rhythm ! I wanna feel your balls hitting my clit! Make them swing harder by thrusting harder ! Oooooooh ! Not enough, not enough, not enouuuugh !" No, he had not.

That said, it was not Marcus' fault. Rather, it looked like Akeno was finding reasons to complain.

Had something put her in a foul mood?

Surely, Marcus was performing more than well enough to sexually satisfy her.

PLAP! PLAP! PLAP! PLAP!

SMACK! SMACK! SMACK!

"UUUUUUUUUNGHHHH !!!" Her crossed eyes, dangling tongue, and endless shuddering were evidence of that fact; Plus the constant outpour of sweat and pussy juice as her body dwelled in overwhelming sexual ecstasy.

By all measures, Akeno HAD to be sexually satisfied. More than that: She HAD to be out of her depth. No degree of athleticism could make a woman withstand Marcus' physical and sexual superiority.

And yet…

"Nghhhhhh ! That's not hard enoooough ! You don't love me… ! Ooooooh ! Why aren't you… ! Uuuuungh ! Giving it to me hard enoooough ?! Hardeeeeer…! Pinch my nipples…! Hurt my tits…! Nghoooooooh !!!" …She found room to exasperatedly complain with her strained voice. Akeno's body had not just developed in terms of flesh growth; It had also become more proficient at handling the Black King's cock and sexual prowess.

…

Why complain in the first place?

Was Akeno not just having sex with Marcus to keep him healthy until Rias came through with the cure?

If Marcus was not having an episode of painful cravings, why even bother demanding so much effort from him? If anything, Akeno could afford to relax and not compromise her body and mind so much.

Something felt wrong.

"I-Issei... I-I can't..." Asia grabbed his arm, in tears. "I can't look anymore…"

"Huh? Ah... I-I agree… Let's go…"

"She's being so mean to Marcus… He's hurting so much…"

"Heh…?" Issei was surprised. "You're worried about HIM? I mean, he's fine, right…? I bet he's enjoying it…"

"No, Issei! He doesn't want to do it! Can't you tell?!" Asia said something absolutely insane.

Even if Akeno was being unusually bossy, there was no universe in which Marcus was a disfavored party.

Just to make sure of that, he took one more look.

"Ghhh! Grrr!"

PLAP! PLAP! PLAP! PLAP!

SMACK! SMACK! SMACK!

"Mnghuuuuuh ! Harder, harder ! Ooooooooh !"

…There was no universe in which Marcus was a disfavored party.

If anything, the victim there was Akeno, who must have been forcing herself to preemptively milk Marcus.

"Nghh ?! Oooooh, it's pulsatiiiiing ! Yeeees, yeees, yeeees, give me your black nut… ! Oh, my, it's gonna be so much, so much… ! Shoot it all up my womb… ! Knock my pussy up… ! Fill me up… ! Make my tits fatter for you ! Uuuuuungh !"

"Grrrr…! Khhh…!" Marcus closed his eyes, tensed his muscles, and clenched his teeth as his thrusts lost rhythm-

"DON'T STOOOOOP !"

"Nghh…! Fuck…!" Marcus opened his eyes with difficulty, keeping them tightly compressed as involuntary tension overwhelmed every muscle in his body.

PLAP! PLAP! PLAP! PLAP!

SMACK! SMACK! SMACK!

"MNGHOOOOOOOOOOOOOH !!! YEEEEEEES !!! FILL ME UP WHILE YOU SHOW MY TITS HOW FAT THEY ARE !!! HIT THESE UGLY, GROSS BOOBS !!!OOOOOOOOOH !!! THAT'S WHY THEY'RE SO BIIIIIIG AND ANNOYING !!! TO BE USED BY A BIG, STRONG MAN !!! UUUUUUUUUNGH !!!" Akeno's lips contorted into a creepy, wide smile that sent shivers down Issei's spine.

Hearing her crazed voice and observing her frantic orgasming were miserable experiences for him. 'Th-this is the same woman I was dating a few days ago…! First I see Rias cum like crazy, and now Akeno?! H-how much is this just the semen corrupting her…? And how much is JUST her?! It's only been a couple of days…! H-how much sluttier is she gonna get moving forward…?!' He observed the area connecting their genitals.

Hardly any cum leaked out because of how plugged-up Akeno was with Marcus' massive black cock. However, the growth of a substantial cum belly around the cock bulge in her navel told the complete story, making her look three or four months pregnant.

Rias needed to come through with that cure as soon as-

"Issei! I think the gym's door is opening! Someone's coming…!" Asia grabbed his hand.

"Huh?" Issei let her lead him away.

They hid in a corner, peeking to see who it was.

Koneko, carrying a backpack.

'Is this a joke?! Was she ALSO following me?! Is someone following HER next?!'

No. It soon became apparent that Koneko had not been following anyone, arriving there on her own. She walked to the center of the gym and stood still, sniffing.

Sniffing…

…Sniffing…

…Sniffing.

Koneko turned toward the equipment room's door and looked at it for a few seconds. Then, she approached it, put the backpack down, and opened the door slightly. "Ah …" Such was the only sound she made upon seeing what was happening.

Either that or it was the only sound Issei could hear her make.

After all…

PLAP! PLAP! PLAP! PLAP!

SMACK! SMACK! SMACK!

"MNGHHOOH ! OOOOOH ! UUUUNGH ! NGHHHH !" …The aggressive sex between Marcus and Akeno had not slowed down in the least, making it hard to hear anything.

"What's wrong with Koneko?" Asia asked in his ear. "She's always glaring at Marcus… And she's shaking… I don't understand, Issei! Do you know…?"

"Uhm… I think it's… Like… The curse…? She must be affected a little because of how her skin got hit a couple of times…"

"But why does she glare like that? Why does she shake?"

"Because... I don't know." Issei did not want to answer.

…But he KNEW the answer.

Anyone who was not innocent and pure would know the answer by simply looking at Koneko's thin legs. Or, more specifically, at the juices running down the thin legs, past her skirt.

'Koneko cums just by looking and sniffing…' Issei had already realized as much. 'C-creepy… Please blink…! I can't stare at that…! It hurts to look at her eyes…! Huh? What's she doing…?' Koneko reached into her backpack and pulled out a towel. 'Is that covered in cum? Is it the towel she used to clean herself after what happened the other day? H-huh?! Why is she doing that?!'

Koneko started rubbing the towel all over her face.

Her arms.

Her shoulders.

Under her uniform's shirt.

Her legs.

Her calves.

Under her skirt.

…Everywhere.

Even her tail and cat ears; Like in the clubroom the other day, they popped out without warning.

Then, she pulled another towel from the backpack and did the same.

And another and another and another…

It must have taken several towels to fully wipe her body the other day. That much was not odd. What WAS odd was why she had the unwashed towels in her backpack, and why she was rubbing herself with them. 'Does she want to get herself covered in his semen…? Is it the texture rubbing on her skin… Does she like that…?'

That might very well have been true but could not be the case for Koneko's actions at the moment. The towels were all dry, so no significant volume of semen had stuck to her skin.

Once Koneko took the last towel and brought it to her nose, Issie understood.

'It's gotta be the smell…' He watched with shock as Koneko's eyes rolled up and her legs convulsed, falling on her knees as a puddle of pussy juice formed on the floor beneath her.

Koneko liked watching, listening, and…

"Mnghhhhhhhhmmmmm …" …Smelling.

Her tail swung about wildly, agitated; Her ears twisted themselves.

…And Koneko drooled from both lips on her body…

"I-Issei, can we go?! I-I don't want to look at any of this anymore…!" Asia had long reached her limits.

"Y-yeah, let's get out of here." With Koneko distracted by the sounds, visuals, and smell, it was easy to sneak behind her and get out unnoticed.

After they left the gym and wandered away, Issei found himself lost in thought.

Too much was changing too quickly.

The things Akeno said conflicted with what Rias told him. Furthermore, he was getting increasingly nervous about the sexual madness presented by Xenovia and Koneko.

'Is everything really okay…? I feel like things are getting out of control. Is Akeno even capable of keeping Marcus in check? Girls in class were looking at him… They like him without having ever even spoken to him! Is this going to get more and more out of control just because he's big and has a big dick?! Is every girl into that?!'

…

His eyes turned to Asia.

It was the fourth time Asia witnessed a hardcore sexual act between Marcus and someone.

Twice in the clubroom; Once at the rooftop; Once now.

…Would Asia, the purest girl he knew, also become depraved like Koneko and Xenovia?

…Like Akeno was becoming…?

'Maybe Rias is secretly like that too…! Th-the things she told Marcus that day… Maybe she's already in love with him!'

Issei felt hopeless-

"That was so gross and viiiiile!" Asia closed her eyes, brought her hands to her face, and whispered in a cute voice, burning red.

"H-heh?"

"Wasn't it?! I don't want to ever see that again! I-it was all too naughty…! I can't handle that! That curse is awful! I can't believe Marcus has to handle that to not die! It's so awful! I would prefer to be dead!"

"You… Didn't find it even a little interesting…?"

"What?! Who would?!" She paused, flabbergasted. "D-d-do you like that sort of stuff, Issei?!"

"Heh?! N-no!"

"D-do... Do I have to... Do I have to like that sort of stuff for you and I to…"

"I don't know what you're talking about, but no! No, it's too much!"

"Th-that sort of stuff should be gentle… And between loved ones!"

"Y-yes! Yes! I mean… Sure!" Issei did not entirely agree but had no intention to express that.

Asia had shown him something he needed.

Purity.

Issei felt hopeful again. 'I'll just trust Rias and hold on. I'm sure everything is alright.'

"I feel so bad for Marcus…" Asia went on. "I can tell he's suffering… Without Rias, I feel like he doesn't have anyone he can rely on right now. Akeno was acting weird in there… Does she really have his best interests as his girlfriend…? Maybe he needs a friend to talk to…"

'Woohoo!' Issei did not care at all, too happy by his newly-found hopefulness.

Asia was a symbol of hope for him.

There was no special appeal to Marcus' large build, muscular physique, or absurdly large penis. It was all because of his semen's corruptive power.

Asia would remain pure as long as she had no contact with it.

Later that day, at night, something happened that left Issei uneasy.

Akeno had sent him a selfie.

'Wh-why…?'

It showed her in front of Marcus, hugged from behind, with her body coated in large dosages of sperm and her large breasts reddened with dozens of slap marks. Because the selfie was angled from below, Issei was able to tell just how much fuller and heavier Akeno's breasts had become. Marcus' face was cut off from the shot due to his height.

Somehow, though, the cum, sweat, and abused breasts were not the main highlight of the shot.

It was her wide smirk, which looked more like malevolent mockery than playful teasing.

Issei was so shocked by it that he felt his heart race. 'Sh-she must think this is just normal teasing… Yeah, now that I think about it, she made some jokes about cheating when it was just me and her too… I thought she understood I didn't like them, but maybe not…' He drew a charitable interpretation of what happened.

That said, Issei had no idea how to 'charitably' read the text that Akeno sent along with the selfie.

'You missed your surprise!'

…

'What was the surprise?!' Issei was confused.

"Issei? Is everything okay?" Rias asked him, entering the bedroom.

"Uh? Ah, yes…!" He quickly put the phone down.

Issei had hoped they would have sex that night, but that was an unlikely scenario now. 'President had even rougher sex with that guy that day…' Images of Akeno moaning her brains out earlier dominated his mind. 'How can I possibly perform well enough to match that…?'

The photo left him feeling inadequate about his own masculinity.

…

'What WAS the surprise?!' And curious.

Three more days passed with no great surprise. Other than that breakfast and the incident in the clubroom, Akeno had kept Marcus all to herself, avoiding grand contact with Koneko or Xenovia.

For Koneko, that was not too big of a deal. She seemed bizarrely content with simply glaring at Marcus whenever possible.

For Xenovia, things were not so clear. She had begun regularly skipping class to eat and drink; Wake up early to eat and drink; Not sleep to eat and drink. The fridge had to be fully stocked again multiple times a day because she devoured and chugged down all the contents within it.

One day, there was only a carton of expired milk in the fridge. Rias, Asia, Kiba, and Koneko would soon come back with groceries. Xenovia could not wait, though, and chugged it all down like it was no big deal.

Interestingly enough, despite the constant eating and drinking, she did not grow fat. There was continued increase in her muscle mass, her breasts expanded slightly, and she seemed to be another couple of inches taller, but that was it. The calories from eating and drinking mostly disappeared into a black hole within her stomach.

…Her lips had become disgustingly bigger, though…

'She ABSOLUTELY looks like someone who added filler to her lips already…!'

Issei could tell that Rias was as worried as him, but she always put on a strong smile and said they would fix it up with the cure for Marcus any day now. 'I wish she'd tell me the details. It doesn't matter… I'll just keep trusting. I'm just worried about Xenovia constantly asking Akeno to let her spend time with Marcus. Akeno says no, and Xenovia looks like she's getting more and more agitated… I swear I saw her growl the last time. Something's wrong with her.'

In the end, Issei ignored his worries. Rias knew better than him, so he just had to power through his discomfort and nothing more.

The present night was too important for him to focus on his insecurities: He would finally man up and have sex with Rias again. 'Since we got back together, she hasn't tried to come onto me. I think that's because she knows I feel weird. But it's happening tonight! We've already talked it through! As soon as I get back from the bathroom, we're doing it!'

…

'So, maybe I should start walking instead of reflecting at a snail's pace…' Issei got a move on.

There was a reason he hesitated: To make it to the bathroom, he had to pass by the door to Akeno's bedroom.

…He was afraid of hearing anything. What he witnessed a few days ago at school had tarnished his memory. Both of his women had been thoroughly branded by rough sex with Marcus' big black cock.

The last thing he wanted was to hear a moan.

Alas, Issei had no idea what he was in for during his bathroom trip.

…A moan would have been the tiniest of problems…

'K-Koneko there again, huh…?' Issei saw Koneko hanging outside Akeno's bedroom door with her cat ears glued to the door and her tail swinging about, excited. Juices flowed down her inner legs. She had a towel glued to her face, sniffing it again and again with agitated breathing. As always, Koneko did not blink whatsoever, ignoring her dry, bloodshot eyes. 'Her obsession scares me… Her tail and ears are out all the time now. Can she even tell I'm walking through? Ah, don't look her way… I'm freaked out…!'

He passed through without-

"Oh, my! Issei? Why are you walking so fast?" Akeno came out of the bedroom at the worst possible moment.

"A-ah… Hey… Akeno…"

"Are you heading to the bathroom? Why don't we go togeth- Out of the way, Koneko. Stop being an annoying brat." Akeno pushed Koneko so strongly that the small girl fell on her ass. In part, it was Koneko's fault for unwittingly blocking Akeno's way in the process of trying to peek into the room; In part, it was Akeno's fault for being unusually aggressive.

She would have never done such a thing a week ago.

Akeno was changing.

…Physically too, with her breasts having expanded multiple cup sizes. 'They're larger than soccer balls… I didn't know boobs could be this big. Her ass too…'

Her hips had grown wider; Her ass had become meatier; Her thighs thicker. In terms of height, though, she only gained one more inch, now standing at 5'10.

The body-changing was not equal in everyone. Xenovia had mostly gained muscle, height, and some breast growth – along with her lips becoming so full that they looked surgically enhanced. Akeno, who had been exposed to far more semen, was becoming thicker and meatier instead of muscular. Koneko – who had the least direct exposure, supposedly – had not changed at all, other than mentally.

"Issei, you're staring at me a lot." Akeno smiled as always, enjoying teasing him.

How would Issei not stare?

Akeno was naked, bearing the marks of hardcore sex. There was THICK cum flowing down her legs and THICK cum tainting her breasts. She and Marcus had clearly been having intense sex before she left the bedroom.

If that was not enough proof enough, there were the hand marks on her chest.

Just her chest. Her ass was clear. For some reason, Akeno had become obsessed with having her breasts struck by Marcus, or so Issei assumed after what he witnessed in the equipment room.

Did she even remember her initial goal was to take care of Marcus until Rias came through with a cure?

"Are they that pretty, Issei? Oh, my, you're going to make me blush!" Akeno laughed.

Had her laugh changed? Or had it always been that devilish and intimidating?

…Was it solely the smell of Marcus' obnoxious cum on her breath…?

That aside, one thing was true.

'They're so big… Heh heh heh…' …Issei loved her new breasts, soon ignoring his anxiety to drool like a buffoon from staring at them.

"You can say it, you know…? I promise I won't get mad."

"I do like them… Heh heh heh…"

"Really…? Oh, my, you must REALLY mean it. Are you enjoying them even when my body reeks of sex with another man? Issei, you're a naughty tit lover aren't you?"

"Uhm… That's…" Akeno's words brought him out of it."

"Oh, don't be that way. I WAS thinking about you, you know?"

"Thinking about me?"

"Yes… I was thinking about how letting Marcus breed me like a slutty cock-loving sow was very beneficial to you and me."

"Beneficial…?"

"That's right. If we get back together, you'll now have a pair of bigger tits to play with. Isn't that wonderful? I'm so happy for you, Issei. All that creamy cum pooled up inside my womb right now is helping my tits grow bigger. Don't you love that? My hips too, which I bet you like as well… My body evolves to be able to match Marcus, I think. I am able to keep up quite steadily with him now that I'm so thick."

"Uh…"

"I can't fit in any of my clothes anymore, but at least you're happy with my new figure, aren't you? Xenovia's got the same issue. She and I are going shopping tomorrow, but we'll have to go with our current clothes. They're so stretched with these huuuge tits and ass I got now… Do you think they might tear off in the store? Maybe you should come with us… I bet you'd love to see that. Ah, but I might take Marcus too. If my clothes tear off, it would just feel right to have him fuck me right there. Would you hold Xenovia off for us? She's been a little annoying, and I like to focus when I'm getting dicked by a big black cock. You'd be able to hear lots, though …"

"Th-that's…"

"I bet you're hoping Marcus fucks me more and more, shooting loooots of juicy cum so your favorite pair of titties can grow even nicer for you ." She laughed again.

Issei did not feel so good anymore.

…He felt mocked…

"Ah… What a crazy experience it is to get railed so hard every day. I'm starting to feel claimed by big black cocks, Issei. Maybe I won't be able to go back to you… I might become one of those 'blacked' pornstars. What do you think? Do you think it'd be sexy if I started filming videos of me getting ragdolled by Marcus? I bet lots of people would jerk off to that. Would you be one of them?"

"Uh… Akeno-"

"Would it be sexy for you if I became the kind of woman who can only get off when pounded by a large black with a sturdy black cock? Oh, my… I must admit that I can't imagine getting my holes filled with anything but sperm from strong black men. It's such a good feeling to be sore from that huge dick …" She gave him a wink and entered the bathroom.

Issei did not know what to say or think. Akeno's behavior frightened him.

"Go ahead. I'll wait for you." Akeno came out.

…With her body still plastered with cum. Akeno did not bother washing or wiping even a single drop off her sweaty, semen-coated front.

"N-no need to wait for me."

"Oh, my." She giggled. "I insist."

"O-okay…" Issei went into the bathroom.

In truth, he did not want to come back out. The maliciousness behind Akeno's voice and words was incredibly painful. That said, they paled in comparison to the pain he felt from seeing her body so viciously used.

Akeno was having regular hardcore sex with a hung, muscular giant. As a man, Issei felt tiny and inadequate.

Was a curse even needed for Issei to be replaced…?

Who would want to have him as 'Harem King' if someone like Marcus was available right beside him?

…Maybe Rias preferred Marcus too…

'Khh…! No, no, no…! It's all the curse! Size and looks don't matter! Height and muscles don't either! Just think of Asia!' The blonde girl acted as an anchor for his self-esteem. 'Akeno is just getting affected by the curse and that's all…! Rias is back with me, isn't she?! She doesn't like Marcus more than me because of his body or anything like that!'

…

Right?

…

'The things she said to him in the equipment room…' Issei had trouble ignoring what he saw and heard. 'She said she was afraid of having sex with him because she could fall in love with him… B-but she's back with me, so that didn't happen, did it? That's right… I don't have to freak out…'

…

Issei held onto his fragmented self-esteem and walked out of the bathroom. 'Please tell me she left…!'

"Oh, my, your little wiener had a lot of pee to let out, didn't it, Issei…?" Akeno had not left, grinning with a tilted head. "Marcus' is like that too… But it's juicy cum instead. It's kind of delicious…" Akeno scooped some off her heavy, enlarged chest with her index finger and licked it clean in front of Issei. "Almost made me cum …"

"Ghh…"

"I cum the most when he uses these, though, you know…?" She brought both hands to her tits and groped them hard, making excess flesh splurge between her fingers from how deeply they sank into her chest. "They're so big now, Issei … Marcus is a bit like you. He loves playing with huge, round tits too … They say black guys make good basketball players. Is that why he likes messing with these so much? But I think a basketball is smaller than these… Are basketballs this heavy, or are my tits too full…?"

"Khh…" Issei tried to look away but failed.

…Her grown breasts were too much of a sight, even covered in cum and slap marks…

"Oh, my, I got your attention, Issei…?" Akeno stepped forward, leading Issei to step back. "You like big tits so much that you really don't mind them being covered in another man's spunk…?"

"H-hang on…" Issei continued to look…

"That's a little gross, Issei…" Akeno stepped forward again; Issei stepped back again. "Shouldn't you be a little manlier and be grossed out? I teased you about cuckoldry a little bit a few days ago and you got annoyed. Now you like it…? Is it all about the boobs, then? If I have bigger boobs, you're more interested in me? You accept anything…?"

"A-Akeno…" Issei continued to look…

"Isn't it wrong for you to stare so much at a pair of boobs that don't belong to you anymore?" Akeno stepped forward; Issei back. "A lot of this new flesh was caused by Marcus' special cum, and he's claimed ownership of my boobs by hitting them a loot . He looooooves hitting and groping them. He might be a bit of a passive boy, but when it comes to my big tits, he goes wiiiild abusing them …" She blatantly lied.

Issei knew the truth from spying into the equipment room with Asia a few days ago. Akeno was more in control of Marcus than she let on.

…But Issei continued to look. Akeno's small hands fondling, kneading, and groping the 'enhanced' chest appended to her body was a mesmerizing sight for a boob-lover like him.

"You should see when he fucks these with his big black cock. It comes out from the cleavage even though they're so big… Because he's got a big, manly black cock ." Akeno stepped forward once more; Issei did not step back.

There was no more room.

He was cornered against the wall.

"He sucks my nipples a lot too …" But Akeno stepped forward again.

"I cum sooooo much each time …" And again…

"If I'm gonna have annoyingly huge boobs, they need to be used properly by a REAL man, don't you think… ?" …And again.

Issei was CRUSHED by Akeno's massive chest. 'Sh-she's taller than me…!' He already knew she held a height advantage from all the body growth, but it felt much, much more significant now that she was smashing him against the wall. Mixed with her thickened-up figure and massive breasts flattened against his chest, Issei felt an unexpected level of intimidation.

Akeno's grin was terrifying.

…

'Ah, they're so big…' …But he still found himself admiring the huge mounds crushing him against the wall, even with them covered in slap marks and cum from another man.

Issei felt pathetic for that.

"Issei… Are you jealous…?" Akeno whispered with her eyes wide open, focused on his. They hypnotized him, making it impossible for him to blink.

"I… Uh…"

"Right before this, Marcus was fucking my tits sooo hard … I really needed to come to the bathroom, but he had such a big nut to bust, so I let him maul my boobs until he was done. I came so good from feeling his body slamming against my nipples and his dick against my chin… It's not just the body. He has a man's instincts to fuck hard … I guess you wouldn't know what that's like…"

"A-Akeno…"

Akeno pressed both hands against the wall, beside Issei's head, leaving him fully stuck in place from front, sides, and back. "How does it feel, Issei…? Why won't you answer any of my questions? Does it hurt to feel another's man's cum rubbing on your clothes…? Does it hurt knowing that I've been milking him a lot with huge tits that you wish were yours every night…? I use my pussy a lot too, though… Marcus is suuuuch a man …"

"Uh…"

"Are you jealous…?" Akeno repeated the question, but this time with a BIG difference: Her face no longer sported a wide smile.

…Just a cold, chilling wince…

"…" Issei said nothing. Not only was he distracted by the wonderful sensation of her huge, soft breasts flattening and splurging themselves against his chest, but her voice and face intimidated him too greatly.

"Oh, my. It's okay, Issei…" Akeno soon smirked again. "…I KNOW you're jealous. How wouldn't you be? My body is getting hotter and hotter, right? Just the type you like…" She leaned forward and brought her lips to his ear. Meaty … Fat … Tits … Even bigger than before… My bras don't fit anymore, I lost my athletic advantage for volleyball, and my lower back hurts, but they should be pretty to you, right… ? At least tell me that much …"

"They're… Pretty…"

"Oh, my…" Akeno removed one hand from the wall and slid it down his side, ultimately resting it on his crotch. "I can tell you think they're a lot more than pretty, don't you, Issei…?" She breathed against his ear, sending shudders down his spine as her hand rubbed his bulge.

Issei was hard.

Earlier, he was worried about getting hard with Akeno due to feelings of inadequacy.

Now, he was hard as a rock in a situation of unmistakable inadequacy.

…Humiliating…

"Hey, Issei… If you ask for it… I'll let you fuck them tonight…" Akeno whispered.

"Fuck… Them…?"

"My tits. I'll let you play with and fuck them as muuuuch as you want." She slowed her voice down while sliding the hand into his pants, directly stimulating his hard penis. "…Doesn't that sound fun…? That's their function, isn't it? To get fucked by dicks… They're frustrating in every other way, just like my fat ass, but they're greeeeat for cock-milking…"

"Khhh…"

"…I'll ditch Marcus for tonight, just for you…"

"Ghhh…"

"…Maybe, for tonight, these tits can be all yours…"

"Nghh…"

"…Just say that you want my tits, and I'll give them to you…"

"H-hah…" Issei was losing his mind from the feeling of her breath – even if cum-smelly – the wonderful sensations of her bare breasts on his chest, and the pleasure coming from her hand rubbing his penis directly.

It was the easiest proposal of Issei's life.

He accepted-

'Wait…!' Issei almost made a grave mistake. 'I-I'm ignoring what President told me…!'

Rias had been simple and direct with Issei: Akeno needed them to remain strong so she could maintain the motivation to handle Marcus until she had the cure sorted out. What was happening right now was nothing more than Akeno teasing him to figure out if he was unable to remain separated from her any longer.

Akeno was strong, so she surely had no issues being without Issei for as long as needed. It was just a test – perhaps mixed with a bit of her personality being influenced by Marcus' semen.

…

But Issei still did not want to say no to Akeno. 'This feels wrong… President, why is it taking so long? Is there really a cure…? What if it doesn't work? Is it really okay to let Akeno sacrifice herself like this…? I hate seeing it happen… It's humiliating to me as a man…'

Issei felt conflicted.

Ultimately, however, what helped him make his decision was Akeno herself. Namely, what she told him multiple times in the past several days.

Issei needed to cherish what he had. If he exposed how much he missed Akeno, she might give up on handling Marcus. That would cause chaos in the peerage and leave Rias unable to figure out the cure since she would have to start handling Marcus again – Rias would never leave Marcus to die.

With the way Xenovia, Koneko, and Akeno were already corrupted, who knew where things would go from there?

It was better for Issei to cherish what he had instead of caving. 'If I don't hold strong, I'll just sabotage myself, like in the karaoke. I won't let Akeno pity me.'

"Issei…? I'm waiting…" Akeno grinned wide with an open mouth, drooling on his ear. "Tell me, tell me… Admit my tits are the best and that you want them … I'll milk your balls dry in return …"

"I'm okay, Akeno." Issie uttered the most difficult words of her life.

"…Heh? You… Don't want them…?" Akeno backed away from his ear, staring him straight in the eyes with enormous surprise.

"I'm fine with President until everything's sorted out. It's okay…"

…

"Is that so…?" Akeno mumbled slowly and without blinking, maintaining steady eye contact; Her hand remained inside his pants, and her chest against his. "…This gross, bigger body is just useless, isn't it…? Second place is second place…"

"What…?"

"…Oh, my! Pretend I said nothing." Akeno tilted her head and smiled very, very widely – a sign that she was happy with Issei's determination and willpower. There was no need to pity him. "These weighty tits would have been wasted on your tiny Asian dick too, so who cares? It's become a little hard to sleep with this much curviness on my figure, but Marcus breeds me like crazy every day, so it's worth it."

"R-right…"

"Very, very worth it…"

"I-I see…"

"Nothing's more worth it than that… Got that?"

"Y-yes…?"

"Great."

…

"A-are you going to let me mov-"

"Are you and Rias having a lot of sex, Issei?"

"Uh… Well, actually…"

"Yes, yes?"

"I was thinking that tonight could be our first night since she got back…"

"Oh, my! So you haven't done it even once?"

"No… I feel self-conscious because of what we saw that day in the locker. I can't even get hard because I'm scared that I won't be enough for her."

"…Hoh." Akeno's smile was gone, replaced by…

…

…Suppressed anger?

Was Akeno wincing again?

This time, it was not a split-second wince; Instead, a constant expression of supposed disdain.

Issei felt inexplicably tiny before her.

"You can't get hard with Rias because you're so nervous that you won't be good enough for her, but you sure are hard for me, aren't you?" She began stroking him again. "What a creative way to insult me."

"Heh…?" Issei did not understand. The reason he was hard was self-evident: Akeno was crushing him against the wall with massive tits.

"So you've been saving up for Rias all this time, huh…?"

"I-I guess you could say that… I need to convince myself that size doesn't matter. I want to be able to do it again with you too- NGHHHHH…! Hey! What are you- KHHHHHH…!" Issei's eye shot up at the same time as his vision went completely blank from AGONIZING sharp pain.

Akeno had SQUEEZED his penis within her small fingers with little to no restraint. "Hey, Issei… Maybe size matters…" She whispered with a creepy glare and unstable voice. "Are you sure you can get Rias off with this tiny little Asian worm you have here…?"

"Stop, stop…! It's hurting, Akeno…! KHHHHHHH…!"

"Does it hurt? Does it hurt a lot?" Akeno went out of her way to BREATHE the smell of cum on his face.

"Yes, it does…! Stop…!"

"What if I squeeze here…?" She moved her hand slightly down, giggling.

It was the sort of giggle no man wants to hear when a woman is grabbing their balls.

"NGHHHHHHH!!!" The reason why was obvious. "Let gooooo!! You're going to crush theeeeeeem!!!"

"Ah, my bad, my bad… I'm not useful to you if I just make you hurt… I have to make you feel good instead, right? Oh, my! I guess that's all I'm good for!" Akeno stopped squeezing and moved her hand back to his length, gripping it tightly – though not nearly as much as before.

And then…

SQUELCHSQUELCHSQUELCHSQUELCH!

"Ghhhhhhhh…!" …Issei endured the aggressive handjob of a lifetime. Akeno pumped his erection with a pace that entirely disregarded his well-being, treating his penis as a toy for her small hand.

"Issei, Issei… You're smart. You know you won't ever fuck Rias again…"

SQUELCHSQUELCHSQUELCHSQUELCH!

"Ghhhh…! Stop…! It's still hurting…!"

"The moment she sees this tiny little prick, she'll laugh at your face and come running to my room to beg me to let Marcus use her womb like a fun bag…"

SQUELCHSQUELCHSQUELCHSQUELCH!

"Nghhhh…! Pleeease…! Slow down…!"

"You don't have the muscles, the drive, or the cock to please a woman like Rias. You may put her in first place, but you're second place to her, don't you see…? I bet that hurts a lot…"

SQUELCHSQUELCHSQUELCHSQUELCH!

"Ooooh…! S-slow…! Down…!"

"Your little man-clit will never make her feel good again. It never did, actually. Rias learned what real sex is like in that equipment room, and she can never forget it. Me too. That's why I have these WORTHLESS fat tits…! To please Black Kings like Marcus! They have a lot of sex drive, so they need women with annoyingly fat tits and gross, curvy figures!"

SQUELCHSQUELCHSQUELCHSQUELCH!

"Khhh… S-seriously…! Please, STOP…!" Issei could hardly open his eyes with the pain coursing through his body. Thrashing about was entirely useless, oppressed against the wall by Akeno's meaty chest and enhanced figure.

SQUELCHSQUELCHSQUELCHSQUELCH!

"She won't enjoy sex with you, Issei… Rias can only cum from having THICK… VEINY… HARD black cocks inside her pussy from now on. If you can't PUSH her womb DEEP into her FUCKING hole, you can't do ANYTHING. Get it, get it, get it?!"

Akeno buried her face in his neck and intensified the pace of her handjob.

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

"KHHHHHHHHHHHHHHHHHHHHHH!!!"

"SHE'S NEVER GOING TO SMILE AT YOU FOR REAL AGAIN! IT'S ALL FAKE! YOU'RE JUST A PAWN! HER ASS AND TITS BELONG TO BLACK KINGS FROM NOW ON. MINE TOO, OKAAAAAY?!?!"

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

"I NEVER WANTED YOU TO PLAY WITH THEM ANYWAY! MARCUS IS MY FAVORITE, NOT YOU! I DON'T CARE ABOUT YOU! I'M A BLACKED WHORE FROM NOW ON. MY BODY IS GOING TO GROW THICK AND GROSS TO MAKE MARCUS HAPPY!"

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

"YOU CAN STAY BEHIND HAVING CRAPPY SEX WITH RIAS WHILE I HAVE AWESOME SEX WITH MARCUS' BIG BLACK COCK! I'LL CHUG DOWN AS MUCH CUM AS I CAN TO MAKE MY TITS HUUUUUUUUUUUGE, JUST SO YOU CAN'T STOP LOOKING AT THEM!"

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

"I…!"

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

"HATE…!

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

"YOU…!"

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

SQUELCHSQUELCHSQUELCHSQUELCH!

"HAH… HAH… HAH… HAH…" Akeno stopped and pulled away from him, breathless from overexertion. "Huh…? When did you cum…? I didn't even notice. This is all you can shoot? How feminine of you…" She examined her hand with disgust on her face.

Issei wanted to say something but did not know what. Even then, he could not speak.

If Akeno was breathless, Issei was dead. The moment she pulled away, he fell flat on his ass, lacking strength in his legs. "Uugh…" Even groaning was too difficult, wheezing instead. Akeno had not just masturbated him to orgasm. She had masturbated him AFTER the orgasm into ANOTHER orgasm… And then some more. 'I've never felt my dick so sensitive…! It hurts even now…! Ghhh…! A-ah…! Why is she looking at me that way…?! Akeno, how much did you change?! Wh-why are you so scary- Heh…?'

Akeno was crying. Nonetheless, her expression wildly contrasted with the idea of sadness, presenting disgust and anger instead. "You're out of gas just from that? To think I offered you my tits… It really would have been a waste."

"A-Akeno… A-are you okay…?"

"Oh, my! Are you worried about me?" Her expression smoothly shifted into her traditional teasing smile – though the tears kept on running. "I don't need your worry. I'm more than happy being a cum dumpster for Marcus' big black cock. Someone has to make good use of my body, don't you think? Ah, but he is a little like you… Neither one of you knows how to cherish me…"

"Akeno, I AM worried about you!" Issie shot to his feet and grabbed Akeno's shoulders. "Something is wrong! Maybe we should talk to President together and- Hey…! Eeew, why did you do that?!" He pulled away from her after she rubbed her cum-covered hand onto his shirt. "Ah, crap…!" Issei was disgusted by the presence of MORE semen on his clothes; Some from him, some from Marcus.

"I don't care anymore, Issei. You should be worried about Rias instead."

"What does that mean…?"

"She's lying to you." Akeno giggled and grinned. This time, there was no doubt about animosity present in her face and voice.

"About… What?"

"Ah, who knows? That's on you to discover. Here, have a parting gift from me." Akeno rubbed her pussy to get more of Marcus' cum on her hand and rubbed it on his shirt again. "There you go. Maybe with a real man's smell on you, Rias will be interested in you. Fucking loser." She turned around and walked away.

"Wait…! Akeno, wait…!" Issei chased after her.

"…Yes?" She stopped, turned her head, and looked at him. "Did you get enamored by my tits and ass bouncing?"

"Wh-what is it?"

"What's what?"

"President's lie."

"…"

Akeno walked away.

Issei felt extremely confused about what was going on in her mind. Even if her mind was affected in some way, it felt like too much for it to be solely that. 'It's no good…! I can't figure her out!'

Nevertheless, there WAS something dangerously off and destructive about Akeno. How else to explain her next action?

"Koneko? Oh, my. You're still at my door? Pervert…" Akeno looked down on Koneko, pissed.

"…I'm just-"

"I don't care." Akeno stared at Issei and offered another devilish grin. "Get in, Koneko. Let's have fun together."

"Yes…!" Koneko rushed in without asking questions, feeling lucky.

"W-wait…! Is that really a good idea, Akeno-"

Akeno shut the door.

"I… Need to talk to President…" Issei could not 'hold on' anymore. 'She has to tell me what this cure idea of hers is. Things are getting way out of control…! I'm scared about what Akeno is becoming…!'

Issei headed for their bedroom.

"HUH?!" …Until his eyes accidentally landed upon a demon right as he passed by a corner.

Xenovia was standing there with perfect posture, glaring.

A coincidence, or stalking?

Issei was caught so off-guard that he froze on the spot. Xenovia wore black short shorts and a black tank top, but neither outfit seemed proper for her anymore, stretched to the limit. Her muscles had been growing significantly day by day, even without Akeno allowing her interaction with Marcus.

Moreover, her height had also increased substantially. 'I think she's 5'10 already? From 5'5 to 5'10 in just a few days?! I swear her clothes are going to tear off if she moves too much…! She's got a full-blown six-pack now, and her arms are covered in veins… Isn't she getting a little too ripped…? H-her legs…' His eyes were drawn to the thickness and definition of her quads, and the veins running across it; The same thickness was present on her ass. 'Her boobs aren't growing as much as Akeno's, but they're bigger too… They have to be at least two cups bigger, right…? It's like she's an Amazon…'

Even if the muscular and breast increase were noteworthy, the biggest change in Xenovia was on her face. More specifically, on her lips. 'It's like a… Small pillow on each lip…' Issei had trouble looking at it. 'It already looks surgically enhanced… How much bigger are those going to get…? Gross… That aside… Why are there crumbs of food around her mouth? Was she eating until now…? And… Why is she drooling and glaring so much at my body…? Wh-what…?!' Issei's eyes shot wide open once he looked at her neck. 'What the hell…?!'

He had to blink multiple to make sure he was not imagining things.

Xenovia's neck was an atrocity; A horror spectacle.

Firstly, it was BRANDED with scratch and strangle marks, with a bit of blood coming out due to cuts caused by what must have been reckless scratching.

Incredibly enough, that was not the main shocker.

…It was the belt TIGHTLY knotted around her neck, constantly pulled by Xenovia's hand to squeeze again and again.

SQUEEZE…! SQUEEZE…!

For how long had Xenovia been walking around, casually strangling herself by tugging on the belt? Based on the veins, muscular tension, and overall redness around her neck and face, she must have been enduring excruciating agony; Yet, she kept tugging and tugging, squeezing and squeezing.

SQUEEZE…! SQUEEZE…!

…With a false smile…

"Are you gonna eat that?" She pointed at his shirt with her free hand; The other continued to abuse her neck with the belt.

SQUEEZE…! SQUEEZE…!

"Xenovia, what are you doing?! That's dangerous…! Get that thing off your neck?"

"Ah, this? Don't mind it. I just have this really deep itch in my throat, it's no big deal. Anyway, are you gonna eat that?" She asked again without blinking, still smiling falsely; Her voice was slightly strained from the pressure on her windpipe.

SQUEEZE…! SQUEEZE…!

"What are you talking about? Eat what?" Issie looked down at his shirt. There was fresh cum all over it. "No…?" He said, incredulous.

SQUEEZE…! SQUEEZE…!

"Ah, you won't?"

SQUEEZE…! SQUEEZE…! SQUEEZE…!

"That's great…"

SQUEEZE…! SQUEEZE…! SQUEEZE…! SQUEEZE…!

"Can I have it, then…?"

"You're kidding, right- Hey…! Hey, hey…!"

"Shlrrrrrrrrrrrrrrrrrrrrrrrrrrrrrp… ! Shluuuuuuuuuuurp… !" Far faster than Issei could react, Xenovia grabbed him by the shoulders and shoved him against the wall, cornering him with her enhanced physique. Once more that night, Issei found himself pressed against a wall by a bigger woman in a frenzied state.

This time, though, there was no conversation or soft breasts to distract him.

"Shluuuuuuuuuuuuuuuurp… ! Shlrrrrrrrrrrrrrrp… !" Just a mad Xenovia licking and biting his shirt like a rabid, thirsty dog desperate for water.

Or, rather, a junkie thirsting for a hit.

That WAS what Xenovia was, was it not?

"Khh…! Hang on…! Don't sink your fingers into me like that!!! Ouch, ouch, ouch…!" Because of Xenovia's frantic state, she recklessly pressed him against the wall without regard for potentially hurting him.

Her itch had to be scratched. Issei had no doubt that if he resisted, she would eagerly fight with him.

"Xenovia…! Stop…! What's wrong with you?!"

"SHLRRRRRRRRRPP… !" Xenovia was not slowing down whatsoever. The more she licked up, the more aggressive she got.

After all, she was orgasming.

Issei could tell even in the chaos of their small scuffle. Xenovia's lower body SHUDDERED, with her six-pack abs contracting WILDLY with each small chug of cum. By the time he looked down to verify, there was already a small volume of female juices on the floor – a product of Xenovia's vaginal lips going mad with sexual ecstasy from feeling Marcus' semen travel down her throat. Amidst the frenzied climax, she tore parts of her tank top and shorts off due to uncontrollably flexing her muscles in the process of physically controlling Issei.

"GHRLRRRRGGHH!!!" Xenovia abruptly broke off from him, covering her mouth with both hands. "What is this awful…?! Bhlrrrgghhh… Ghlrrrrgh…!"

"H-heh…? Xenovia, what are you- Oh, come on…!" Issei could not help but recoil at what had just happened.

Xenovia puked on the floor.

"Aaaaah…! No…! No, no, no...!" She got on her knees and stared at the disgusting pool of food and fluids with misty eyes. "I wasted it…! Why did this happen?! No, no, no…! What was that awful taste?! It's not my fault…! Grrrr…! This is YOUR fault…!" She shot to her feet, cornered Issei against the wall, and glared at him, this time with RAGE plastered on her face. "What was that awful liquid?! That couldn't have been Marcus' semen…!" One of her hands immediately moved to the belt, tugging it again to strangle herself.

"I-I d-don't know…?! Oh…! M-maybe it was m-m-mine…? M-m-my semen…?" Issei shivered in fear. Whereas Akeno intimidated him on a psychological level, Xenovia intimidated him physically. Her defined arms, shoulders, abs, and superior height made her look far more imposing than anyone else in the peerage, other than Marcus – though, the black giant lacked the aggression that Xenovia expressed.

"Huuuuuuh?! That thin crap you showed me in the karaoke?! You made me drink THAT?! Why didn't you FUCKING SAY SO?!"

"I-I didn't even think about it…! X-Xenovia, I-I need to go, so…!"

"No, no, no…! AH, what do I do, what do I do…?! I'm going crazy…! I just need a little bit, just a little…! Just to stop this itch…! I'm so thirsty and hungry…!" Xenovia backed away from him, swinging from rage to panicked agitation again. "I can't anymore…! Please…! I can't do this anymore…!" She brought both hands to her neck, tore the belt off with raw strength alone and…

…

Issei could not believe what he was seeing. "H-hey… T-take it easy…"

"I can't, I can't, I can't go another second, please, I need a little, please…" Xenovia PSYCHOTICALLY clawed her neck. The more she moved her fingers, the more Issei shivered. The deep indentation from the belt that had been on her neck a second ago was equally frightening to look at.

It was a visual horror show. Xenovia had strangle marks, scratch marks, and DENSE veins across the entire length of her neck.

Whatever frenzy Issei was seeing now was just a small segment of a much larger picture. Xenovia was going crazy with oral fixation; It would not be surprising if she hurt herself by accident – or not.

"Give me some…! You give me some then…!" Xenovia swung back to rage, still scratching her neck. "Give me cum…!"

"I-I don't have more of Marcus-"

"It can be YOURS! Fuck it! Give me YOUR cum…!"

"H-h-here, I'll give you my shirt and you can-"

"IT HAS TO BE FRESHER THAN THE CRAP YOU HAVE THERE!"

"Th-this IS fresh! It just- Khhh…! Wait, Xenovia…!" The blue-haired psycho tore his pants, shot to her knees, and buried her face in his crotch with her jaw dropped, taking his full penis inside her mouth with remarkable ease. "Ooooh, shit…" The feeling of her enhanced, pillowy lips against his crotch was unexpectedly heavenly.

"Shlrrrrrp…! Shluuurp…!" Xenovia did not move her head back and forth, using only her tongue to stimulate his penis.

His soft penis.

Issei did not have the stamina to shoot more than once every few hours, and Akeno had drawn two loads out of him with plentiful overstimulation. There was no possibility of him getting hard again, thus making it borderline impossible for him to ejaculate.

"Shlrrrrrp…!" That did not mean Xenovia would stop…

"Shluuuurp…!" …Or slow down…

"SHLRRRRRRP…!" …But she might get FURIOUS…

"SHLUUUUUURP…!" …And grab his balls.

Issei only had a fraction of a millisecond to realize what would happen after Xenovia grabbed his balls.

The good news was that he DID realize what would happen.

The bad news was that his realization was entirely inconsequential.

Xenovia squeezed them far faster than he could react.

"…" Issei did not scream.

Too much pain.

Blank vision.

Loss of mobility.

Whatever strength Akeno used earlier was a joke compared to the reckless, agitated Xenovia.

By the time the pain had stopped, he was on the floor, whimpering in pain…

"What are you good for?! How are you the same sex as Marcus?! What's the point of having balls if you can't use them?! HUH?! WHY DID YOU MAKE ME PUKE HIS CUM OUT IF YOU WOULDN'T GIVE ME ANY?!" …And Xenovia was berating him with maniacal fury. "You piece of shit…! Khhh…! I just need a little bit…! Just a little bit…! You ruined it…! You're not a man, you're just a worthless piece of shit…! If you were a man, you'd have a dick, not that useless thing…! I hate you…! FUCK!"

THUD!

"NHGAAAAAH!!!" Issei spasmed from the strongest pain of his life: A kick to the balls.

It was the only one, thankfully. Xenovia soon stopped berating him and wandered off on her own, scratching her neck and crying to herself about her itch.

Then, she stopped in front of Akeno's door and knocked on it.

KNOCK!

KNOCK! KNOCK!

KNOCKNOCKNOCKNOCKNOCKKNOCKNOCKNOCKNOCKNOCKKNOCKNOCKNOCKNOCKNOCKKNOCKNOCKNOCKNOCKNOCKKNOCKNOCKNOCKNOCKNOCKNOCKNOCK!!!!

Xenovia had long lost her mind.

Was that a sign of the future? Would Akeno lose it the same way?

'President said that everyone is affected differently… Then, did Akeno lose it already?! Which one is more far gone?!'

"Akenooooo! Pleeeease…! I just need one load…! Pleeeease…! Just a few drops…! Anything…!" Xenovia continued to slam the door with one hand while scratching her neck with the other.

For a long, long time.

It was a miserable sight. Issei almost pitied her if not for the pain keeping him paralyzed on the floor. 'It hurts so much…! Ghhh…!'

Considering how unstable, angry, and possessive Akeno had been acting, there was no chance of her letting Xenovia into the room. Her letting Koneko in already made no sense.

"Hoh…" Akeno opened the door, sweaty.

"Ah…! A-Akeno…! Please…!" Xenovia scratched slower to not look as freaky in front of Akeno.

"…Didn't I tell you that I don't like sharing? Get over it-" Akeno's eyes noticed Issei.

…

"Come in." She grinned and let Xenovia pass.

"YES! THANK YOU!" Xenovia rushed into the room, drooling.

"Oh, my…" And then Akeno closed the door after giving Issei a last glance.

…

Was she going out of her way to punish Issei for something…? 'Did I… Do something to anger her…?'

Most likely, but Issei lacked the emotional intelligence to know what. Regardless, he was now left with an altered Akeno who wanted to get back at him for some reason.

What should Issei do from now on?

The answer was not clear, but what he should NOT do was blatantly obvious.

And yet, he did it anyway.

Issei approached the door to Akeno's bedroom, realizing she had left it slightly ajar.

…To peek…

'It's been a while since Issei went to the bathroom… Well, it gives me time to think.' Rias reflected while lying down on the bed, wearing nothing but lace-trim red lingerie.

Issei and Rias had not done anything sexual since getting back together, so she hoped to seduce him once he came back from the bathroom.

Sex needed to happen to prove that their relationship was fine.

…To prove that she still desired Issei…

…

But, if Rias did desire Issei…

'Ah… I miss Marcus' big black cock…' …Why did Rias constantly think back to Marcus?

Every day, her glances were toward Marcus. Every night, her dreams were of Marcus.

Only Marcus.

Rias never thought about sex with Issei, not getting even slightly aroused from seeing her boyfriend shirtless whenever they went to sleep.

It was nigh impossible.

How could she get aroused from looking at a skinny, average-looking man like Issei?

…Rias had tasted better…

'Stop thinking that…! Body isn't everything…! I love Issei for his personality…! He loves me so much too, how could I not love him back?'

Indeed, Issei's strong feelings for Rias were one of the components of her attraction to him.

So why had Issei not come onto her since they got back together?

…Did HE stop loving her…?

'Maybe… Maybe he secretly hates me for having done things with Marcus? He doesn't know most of the stuff we did, right…? He should only have seen the thighjob and handjob I gave him that second day, in the clubroom… Is that enough for him to stop loving me?'

If Issei had seen the stuff Rias did to please Marcus, he might have lost all attraction to her; He might have become disgusted with her. What man could love a woman that gave rimjobs and endured hardcore sex with another man? Especially sex that involved her cumming into going crazy.

…Issei would hate her if he knew…

If Issei no longer cared about her, then…

…

…Then, maybe, she should just go back to Marcus and start milking him again…

…It might even be the most responsible choice…

…Rias could get to cum on that powerful, sturdy cock again and again…

'What am I thinkiiiiiing?!' Rias shot to a sitting position. 'This is it…! I've been thinking way too many weird things! I am DEFINITELY affected by the curse too…! It's the only way to explain it! As heir apparent to the Gremory Clan, I have to fight this!'

…

Fight how, exactly?

…

'By focusing on something else…! Avoiding stressful thoughts!' Rias had a good idea.

Thus, she thought of something else.

…Such as how her peerage was crumbling further with each day. 'Khhh… Akeno is losing it… She's been acting jumpier and jumpier with each day. Her body too… It's changing so much faster than I thought. Her clothes don't fit anymore, and she cropped the shirt and skirt of her uniform to keep them from tearing up at school. I had to ask Sona to get the teachers to ignore the fact that she's looking like a bimbo with no bra under her cropped uniform… It's not Akeno's fault. They are so round and big, and her ass too…'

"Nghmmm …"

Xenovia, too, was changing too much, too quickly. 'She's looking like a mini-bodybuilder. Xenovia was always fit, but a full set of abs… The other day she tore her shirt by accident from trying to scratch her back. Her legs are ridiculous now… I didn't know you could have veins on your quads… Her boobs aren't as big as Akeno's, but… She's so tall now… Is she going to cross six feet at this rate…? Forget all that, the worst part is her face. What are those lips?! They look made to…'

"Ghnmmmmm …"

To suck dick, which was exactly what Xenovia was desperate for every single day. Akeno had not been letting her do anything with Marcus – which was a good thing – but it seemed to make Xenovia more impatient with each passing day. 'A little like Akeno… But Akeno just looks moody. Xenovia looks like a junkie instead. Why is she always scratching her neck too…?'

"Unghhhhh …"

As for Koneko… '…She doesn't seem to be changing physically, but she has her cat ears and tail out all the time now. I feel like she's been quieter than usual. Is it because she's always immersed in stalking Marcus and glaring at him…?'

"Mnghhhhmmm …"

'It's all going to hell.' Changing focus just made Rias more stressed. 'How long is it going to take Sona to find something? What do I tell Issei? How much worse is it going to get? I made a big mistake by abdicating all control over Marcus to Akeno. Maybe I really should go back to him… And start letting him shoot that awesome cum deep in my- Stooooop!' Rias cut herself off again.

"Ooooooh …"

'Th-these intrusive thoughts…! Khhh…! It's just because I'm horny, isn't it?! So, if I'm not as horny, I'll control myself better, right?! Issei is taking too long, so maybe I should touch myself up a bit! It'll get me wet for him too! Then we can have sex and resume a normal dating life!' Rias decided to masturbate to fix her situation.

There was but one problem.

"Uuuuughnnn …"

Rias had been masturbating all along without realizing it.

"Nghhhhmmm …"

At no moment did she genuinely think of her peerage to find solutions.

"Mnghhhmmm …"

She just wanted masturbation material; Her thoughts were food for her touches.

"Ghnnmmmm …"

Her masturbation method was curious, though. There was no hand directed at her crotch.

"Oooooooh …"

Instead, Rias had both hands frantically rubbing her nipples up and down inside her lingerie; The same two places that she coated with Marcus' cum the other before leaving the clubroom to go home with Issei.

Rias remembered the feeling even now, days after; The inexplicably fulfilling sensation of having Marcus' powerful, sticky sex juices glued to her sensitive nipples. Even after showering, she could feel as though the sperm was there.

…Making her cum…

'I came three times while walking home with Issei…! Just from having cum on my nipples…! Haaah … I kind of wish I had some more now…! Ghnmm …'

Sadly, there was no semen for her to use at the moment.

So, she just used her memories.

"Nghhhhhhh… !" They were enough to make her cum harder than she would with…

…

With whom, again?

Marcus' big black cock was the only thing on her mind.

Issei froze up once he peeked through the door.

There should have been no surprise that the contents within the bedroom would be sexual in nature, but his expectations were still vastly surpassed.

…A spectacle of degenerate devotion…

"Ghlurgh ! Shlurp ! Bhlurgh ! Shlorp !" Bhhlrgh !" Xenovia had wasted no time squatting to her tiptoes to PASSIONATELY facefuck the standing Marcus, engulfing the full length of his turgid, thick cock with ease that defied reality.

"Bhlrugh ! Shlurp ! Shlrrp ! Ghlugh ! Every single motion ended with her pillowy lips buried in his crotch and a PROMINENT bulge spanning her entire neck and some of her upper chest. Xenovia had not even bothered removing her ripped clothes, letting spit and sweat drip down her chin and ruin her tank top further, sliding down between her cleavage and the crevices of her six-pack abs.

"Shlurp ! Ghlrgh ! Bhlrgh ! Ghlorgh !" Xenovia had no regard for her own health, as was apparent by the redness of her oxygen-deprived, cheeks-puffed face. Undoubtedly, she would happily facefuck herself into unconsciousness as long as it meant getting more of Marcus' big black cock into her throat.

…

Was it 'happily'?

Or was it 'obsessively?'

The look on Xenovia's offered little information, ruined by tears, snot, and spit bubbles. Only a couple of minutes had passed, and she had already turned her face into that of a mindless, cocksucking pornstar, reaching around to sink her fingers into Marcus' asscheeks for better leverage, pulling her face into his crotch again and again.

Funnily enough, Xenovia's hands on Marcus' asscheeks provided unintentional aid to Koneko, who was…

…

…What WAS she doing?

It was blatantly obvious, but Issei still had trouble acknowledging reality.

'She's… Sniffing his asshole…?'

By all measures, that seemed to be Koneko's sole action. She was standing on her feet and slightly bent forward – which was all she needed thanks to their height difference – with her nose SUNK into Marcus' crack, sniffing and sniffing.

Issei could tell she was sniffing because…

SNIFF…! SNIFF…! SNIFF…!

…It was loud. Koneko was LOUDLY sniffing Marcus' taint.

That was all.

Nothing more special than that.

Koneko was merely indulging her sense of smell.

"Nghhhhhhmmmm …" It was all she needed to orgasm plentifully, as could be told by the wild swaying of her cat tail, the twisting of her cat ears, or the general quivering of her petite body. Koneko, too, was not naked, but her shorts had already been ruined by repeated gushes of pussy juice soiling the fabric from the inside.

Even Xenovia had not orgasmed as much. It was hard to tell if the blue-haired girl drew intense pleasure from 'scratching' her throat with Marcus' big black cock, or if she had a compulsion to do it. It was true that she trembled nonstop as well, but that might have been from excruciating oxygen deprivation alone; Every inch of exposed skin of Xenovia's figure was marked with veins and bulging muscles – not as much as Marcus, but more than any other girl in the peerage or at school.

Issei was disgusted by the show of degenerate devotion taking place. How was he supposed to ever be the Harem King with women like that? 'I-I can't forget seeing this… Khh…! And look at his face…! Why is he looking all nervous and uncomfortable?! Marcus, you piece of shit…!'

There was still room for things to get worse, though.

After all, Issei had been ignoring looking at Akeno.

She was on the edge of the bed, lying on her stomach, looking at the two girls servicing Marcus with an arrogant smile. "This is not enough, you two…" Akeno got up and moved beside Xenovia. "You can go faster than that, can't you?" She grabbed Xenovia's hair and began assisting with her motions.

SPLAT! SPLAT! SPLAT! SPLAT!

"GHLRGH ! BHLRGH ! SHLRRP ! SHLURP !" What was already a frenzied facefuck session somehow increased in intensity, with gushes of spit and precum leaking more and more out of the sides of Xenovia's over-extended mouth.

Not for long, though.

"GHLURGH ! Stop it!" Xenovia did the unimaginable: She slapped Akeno's hand off and stopped sucking for a moment.

Too long of a moment, it seemed. Even a second without the cock in her throat led her to start scratching her neck again.

"Excuse me…?" Akeno asked, no longer smiling.

"I-I mean… I-I can suck him myself. You don't need to-"

"You only get to suck him because I let you. Marcus is mine. You do what I say." There was no emotion or increased aggression in Akeno's voice; Just cold command with a slight glare.

"Y-y-yes…" It was enough to intimidate Xenovia.

"Then…" Akeno grabbed the back of Xenovia's short hair again. "…Get sucking." She pushed the muscular girl's head toward Marcus' crotch once more.

SPLAT!

"GHLRRRRGH !"

And then many, many more times, much, much faster.

SPLATSPLATSPLATSPLATSPLATSPLATSPLATSPLAtSPLATSPLATSPLATSPLATSPLATSPLAT!!

"GLRGH ! BHLRGH ! GHLRGH ! SHLRRRP ! GHLRRGH ! BHLRRRGH !" Xenovia's face became substantially redder, with veins peaking in thickness at her neck. Quite clearly, she was being pushed to her limits.

Right then, she began matching Koneko's pussy juice production. A waterfall of female cum exploded from her pussy, leaking through the fabric of her shorts in the form of a rain of sex juices. The rest trailed down her inner legs. Soon enough, a thick, smelly puddle formed on the floor.

"Keep that up." Akeno giggled and let go of Xenovia's hair.

Surprisingly enough, the girl DID keep the rhythm up. Xenovia liked it, she just had no idea of her own brutal facefucking capabilities.

SPLATSPLATSPLATSPLATSPLATSPLATSPLATSPLAtSPLATSPLATSPLATSPLATSPLATSPLAT!!

"BHLRRGH ! GHLRRGH SHLRRRP ! BHLRGGGH ! GHLLRRRRGH ! SHLRRRRP !" Her endless self-throat-abuse became ambient noise.

"You too can do better, can't you, Koneko…?" Akeno walked over to Koneko next. "Aren't you being selfish, just sniffing like a mindless animal…? Shouldn't you do SOMETHING to make my boyfriend feel good? Why not give him a rimjob…? Don't you think so, Marcus?"

"Yes, Master…"

SNIFF…! SNIFF…! SNIFF…!

Koneko offered no response, possibly unaware of anything other than her sense of smell and continuous state of quivering orgasm. Because of how buried she was into Marcus' ass-crack – to the point that her nose and eyes were virtually out of view – Issei had no clue if she was even conscious.

"Koneko…" Akeno whispered with a hint of frustration.

SNIFF…! SNIFF…! SNIFF…!

"Koneko…!"

SNIFF…! SNIFF…! SNIFF…!

"Koneko!" Akeno grabbed Koneko's hair and pulled- "Are you kidding me?!" Akeno failed to pull Koneko. The cat girl sank her nails into Marcus' asscheeks to remain in place. "Get out of there…! Answer me…! Khhh…!" Akeno pulled harder and harder.

Issei witnessed a ridiculous tug-of-war between Koneko and Akeno. One woman wanted to sniff Marcus' asshole into infinity. The other wanted to talk her into sniffing AND licking Marcus' asshole into infinity.

An absurd sight.

And, to add music to it…

"GHJLRGH ! BHLRGH ! SHLRRRP ! BHLUURGH !" …Xenovia continued to gouge her throat out, also into infinity.

"You're strong, aren't you, Koneko…?" Akeno breathlessly gave up on pulling Koneko's face from her entrenched position. "Forgive me for this, then." She raised her foot and stomped Koneko's tail.

"KYAAAAAAAAAH!!!" Koneko finally let go, throwing her head back in agony. "Stop …!"

"I will once you listen to me." Akeno wrapped the tail around her fist and condescendingly stared down at the small girl. "Service my boyfriend and quit being so selfish. I don't care how self-centered or obsessed you are with his smell or the touch of his skin. If you're here, you have to show service. Ah, aren't I the best girlfriend? Right, Marcus?"

"Yes, Master…"

"Yes, what?"

"Yes, you're the best…"

"Your favorite girl, right…?"

"Yes."

"Aaah, I love you too ." Akeno blushed with a big smile; Then, she coldly stared back at Koneko. "Start using your tongue."

"…" Koneko looked away.

Issei was surprised to see Koneko so defiant of Akeno's command. 'I thought she was obsessed with Marcus? Maybe she isn't as corrupted as Xenovia and Akeno…? Can Koneko still be saved?! I mean, they're all gonna be fine once Rias has the cure, but I mean until then…'

"Ah, wait… I see what's happening now…" Akeno giggled and smiled, squatting until her face was level with Koneko's. "…You're ashamed of it, is that it, Koneko…? You don't want anyone to see it, is that it…?"

"…" Koneko blushed and averted her gaze further.

"Don't look away from me…" Akeno glued the front of her face to the side of Koneko's; They looked like two cats on the verge of a fight, though one was clearly in control of the other – especially because the one happened to have the other's tail under her grip.

Koneko obeyed and side-eyed Akeno.

"I get it, Koneko…" Akeno grabbed Koneko's chin and gently inserted a thumb into her lips. "…I hate how my body is changing too. It's gross, isn't it…? I think so too… Look at how big my tits, ass, and legs are getting… And I'm getting taller too. I never thought I was 'cute', but now I just think I'm an outright whore. No one will ever look at me again and think that I'm a lovely, charming woman. They'll just see a sexhole made of excess flesh to knead and use. I already hated how my tits got in the way of me playing volleyball before, so imagine now… Sex is all I'm good for from now on. To be stared at and fucked… It's especially annoying when there's no one you care making good use of it, isn't it? Feels like a humiliating waste…"

'What…? Did she always feel that way…?'

"But, you know… I'm okay with it because I have Marcus to love my thick body. He's huge and hates his body too, so he gets me… And he looooooves using my tits, because he loves me as his number one love, right, Marcus…?"

"Y-yes, Master…"

"Oh, my! So you see, Koneko? There's no need to be ashamed or grossed out by how your body is changing. Follow Xenovia's example. Look at how brave she is for accepting how she's changing."

"GHLRGH ! BHLRGH ! GHLRGH ! SHLRRRPR !" Xenovia gave absolutely no fucks about her changing body – for better or worse.

"A-anyway… Let's all be grossed out with our new bodies together… Marcus will make it worthwhile for you, okay… ? Show yourself to me, Koneko… I promise I won't laugh…" She inserted her index finger into Koneko's mouth next.

Issei failed to follow Akeno's words. 'What's she talking about? Koneko is the only one whose body didn't change in any way. I don't- What the…'

He was wrong. Koneko had changed plenty. They simply failed to notice it because she had been going out of her way to speak little, hiding the growth in a certain part of her body.

"Isn't it beautiful…?" Akeno grinned, slowly pulling Koneko's tongue out of her mouth.

…For much longer than should have been possible.

Koneko's tongue had grown extensively. Issei observed in awe as Akeno slowly pulled the full length out of her mouth. Each time he thought it was over, another inch appeared… And then another and another and another…

"Oh, my… It's even bigger than I thought." Akeno noted after the full tongue was out. "How long is this, Koneko…? Seven…? No, eight… Eight inches…? Congratulations. Your tongue is WAY bigger than my ex-boyfriend's dick."

"Mnghl…" Koneko groaned, blushing so much that it would have been cute if not for the context. Her tongue was not only long, but also unusually wet, RAINING saliva on the floor while Akeno kept it pulled out by the tip.

"Now that we've exposed the shameful tongue you've been hiding in your mouth, there is no reason to hold back, right, Koneko?" Akeno got up and grabbed Koneko's hair, gently pushing her toward Marcus' crack. "Sniff it up as much as you want. And while you're at it, make your enhanced tongue useful. Because it's so long, you can do something none of us can. I wanna see it…"

Koneko's face was dug into Marcus' ass again.

SNIFF…! SNIFF…! SNIFF…!

At first, all she did was sniff and sniff, soon entering another constant state of trembling and tail-swaying.

Soon enough, however, Issei learned what Akeno meant.

"Shlrrrrrp … Shluuuuuurp …" Koneko could bathe Marcus' low hanging balls while keeping her nose buried into his asshole; A feat only possible due to the excessive length of her tongue.

At first, Koneko licked very slowly and gently, unaccustomed and ashamed.

In a matter of seconds, that gentleness vanished.

"Shlrrrp ! Shluuurp ! Shlooorp ! Shlrrrrrrp !" Koneko began licking Marcus' heavy, low-hanging sack as if her life depended on it, ending each motion at his asshole; A 'sackjob' and rimjob combo. At the same time, she continued to fervently sniff.

She had learned the feverish pleasure of rubbing her tongue on Marcus' scrotum.

At that moment, Issei finally understood the way in which Koneko was affected by the curse: Her senses had grown very, very sexually sensitive.

Sight;

Hearing;

Smell;

Touch;

Taste.

All five of these senses had become erogenous tools for Koneko. She glared at Marcus because it made her cum. She listened to him have sex because it made her cum. She sniffed because his odor made her cum. She touched him because it made her cum.

And, now…

"Shlrrrrp ! Shluuuurp !" She feverishly bathed his balls and asshole with her spit, taking in the direct flavor of the muskiest, sweatiest parts of his body into her tongue, which made her cum.

Everything related to Marcus made her cum.

Sex was not needed; Just the most basic of sensory perceptions.

Every few seconds, she licked all the spit on Marcus' balls back into her mouth and swallowed it all. Whenever those moments came, her entire body spasmed AGGRESSIVELY more than usual.

"Shluuuurp ! Shlrrrrrp !" And then she repeated the same thing again and again.

"Oh, my! What a spectacle." Akeno let go of Koneko's hair and tail, satisfied. "I must be the best girlfriend in the world, don't you think so, Marcus?"

"Yes…"

"What other woman would let you have this sort of hardcore sexual pleasure? I am dominating these pesky, slutty brats just to get you off. You value that, don't you?"

"Yes…"

"So, if you could choose between me and anyone else, you'd choose me, wouldn't you?"

"O-of course…"

"Then, why aren't you playing with my tits yet?" Akeno stopped smiling. "Are you lying to me?"

"No…! I just thought… You were busy with them so…"

"Are YOU busy with them?"

"H-heh?"

"Are they servicing you so well that you don't care about me anymore? I'm secondary to these two girls that I let you have? You don't want me anymore? You want them over me? You don't need me?"

"Th-that's not what I-"

"Then play with my tits!" Akeno stood beside him, locking eyes. "Play with them!" She cupped them from below, raising them. "Play with them!"

Was breast play truly Akeno's own form of corruption…?

"Nghh … Don't just fondle them, you buff giant… 'Play' with them." Akeno ordered again.

"Ghh… Yes…" Marcus hesitated to obey her command.

Issei quickly realized why.

SMACK! SMACK! SMACK!

"Mnghhh ! Ooooh ! That's it…! Hit them hard… ! MNGH !" To Akeno, 'playing' with her boobs meant 'abusing', just like in the school gym's equipment room.

SMACK! SMACK! SMACK!

"UUNGH ! Yes…! Show these worthless titties how fat they are…! They're gross and ugly…! Punish them…! NGHHH !" Every time Marcus descended his large hand onto her chest flesh, she quivered in pain AND pleasure.

SMACK! SMACK! SMACK!

"GHNN ! I hate them…! I hate them, I hate them, I hate them…! Make them suffer for ruining my beautiful looks…! I'm becoming a sex ogre…! So make them count for something by showing them some pain…! OOOH !" Her pussy lips twitched and throbbed with each contact, gushing small volumes of female juices on the floor.

Rough breast stimulation. Issei settled on that interpretation.

Interestingly enough, he changed his mind minutes later after seeing Akeno turn around and bend slightly, offering her THICK, FAT ass for him to hit.

"There next…! Show my ass how ugly and fat it's become too…! NGHHM ! OOOOH !" Akeno trembled just as much from feeling her ass being abused by vicious palm strikes. Satisfied with her breasts being fully marked, now she wished the same for her enhanced rear.

Xenovia was orally obsessed.

Koneko had her senses overenhanced.

…And Akeno had turned into a masochist?

On an instinctual level, Issei felt like that was incorrect.

The real truth came to him a few minutes later, after Akeno's bubble ass had been fully branded by Marcus' large hands.

"Nghhh… ! You just can't do it hard enough, can you…?! Why not…?! Why is nothing I give you enough for you to show the same devotion to me that I'm showing to you…?!" Akeno grabbed Marcus' cheeks and pinched them with misty eyes, on the verge of tears. "You don't love me?! You prefer Rias over me even after everything I've done for you…?! Who the fuck milks you as much as I do?! Why am I not enough, Marcus?!"

"M-Master, please…! Khhh…!" Akeno was pinching his cheeks hard enough to actually hurt.

"Oh, my…! It's okay, you'll come around…! I know you'll come around…! I'm not going to accept that my body is getting this gross and sexual for nothing…! So I know you'll come around to love me…! Obsess with me…! Worship me…! I mean, look around you…!"

SPLATSPLATSPLATSPLATSPLATSPLATSPLATSPLAtSPLATSPLATSPLATSPLATSPLATSPLAT!!

"BHLRGH ! GHLRGH ! SHLUUURP ! SHLRRRRP !" Xenovia continued to animalistically destroy her face on his hard, lengthy cock.

SNIFF…! SNIFF…! SNIFF…!

"Shluuurp ! Shlrrrp ! Shlooorp ! Shlrrrrp !" Koneko continued to smell his ass while bathing his balls with her long tongue.

And Akeno…

"No woman is ever going to give you this much pleasure, okay?! I'm the best one for you…! My body is the best too…! It's changed for you…! It's grown for you…! It's become ugly for you…!" …Continued to be unsatisfied, resentful, and authoritatively angry.

That was Akeno's variation of the curse: intense enhancement of negative feelings. Her worst traits were stimulated out of proportion, much like her hips, breasts, and thighs. She was no masochist; Just someone that could not be satisfied.

Issei wondered if those were natural feelings she had before being affected by the curse, or if they were planted from scratch by the curse.

That, he lacked the emotional intelligence to know.

Either way, nothing could be worse for the one woman who was supposed to keep Marcus in check.

…

Issei should have left to talk to Rias; Explain the situation. She might not have been aware of how long-gone Akeno seemed to be.

He knew that.

But seeing Akeno issue new commands made him curious to watch just a little longer.

"Right there, right there…! If you're going to be mean to the one woman who loves you the right way, you don't need to speak, right…?! Oh, my, I bet you're enjoying this anyway!" Akeno laughed and giggled devilishly, sitting on Marcus' face.

He had lied face-up on the bed with his legs spread wide open. That way…

"Shlrrrrrp ! Shluuuurp ! Shlooooorp !" …Koneko could lie chest-up between them with her face smothered by his oversized balls to sniff and lick. Her tail endlessly swayed in giddy joy from having her tongue and nostrils overwhelmed by Marcus' scent and taste.

"GHRLGH ! BHLRGH ! GHLRRRRGH ! BHLUUUURGH !" Meanwhile, Xenovia lied on her stomach and hammered her face up and down along Marcus' full length. She was unexpectedly proficient at taking his entire cock again and again with no slowdown – likely a consequence of how her body had been modified by all the sperm consumed in the previous days. The bulge in her neck, overstretching of her jaw, and constant state of oxygen deprivation did not affect her. In fact, she probably preferred it. Most notable of all, though, was her enlarged lips acting as a spring every time she sank them into the base of Marcus' shaft, giving her a small bounce to pull all the way up before once more maniacally sinking down.

And, while the two girls sloppily and nymphomaniacally serviced Marcus' genitals one way or another, Akeno rode his face.

"Nghhh ! Mnghh ! Unghh !" …A lot. Akeno bit her hips, grinding her hips back and forth to rub her pussy on Marcus' face. She was not using his tongue; Just his face's skin to scrape herself into orgasm by stimulating her wet, sensitive pussy lips.

Marcus almost looked like a victim of Akeno's deranged, warped mind.

Xenovia was deepthroating him, yes…

Koneko was showering the underside of his heavy balls with spit, yes…

Akeno was cumming and squirting on his face, AND getting two girls to service him, yes…

…But he still looked like a victim, controlled by her.

For that one quick second, Issei pitied Marcus.

Then, Marcus' body began thrashing wildly, matched by equally frenzied and desperate grunts of masculine pleasure.

He was ejaculating.

"GHLRGGHHHH !!!" Xenovia's cheeks exploded into puffiness, and her eyes rolled back. Based on how her motions stopped after fully digging her pillowy lips into Marcus' crotch, it was easy to tell that she was melting in mindbreaking euphoria – the intense squirts that she blasted on the bed after that were further proof.

"Shlrrrrp ! Shluuuurp !" Nothing changed for Koneko, who had fully immersed herself in sniffing, licking, and munching Marcus' large black balls.

Something did change for Akeno, though. "Woah…! Nghh !" She was forced to stop riding Marcus' face because he crunched his torso back into a full sitting position, hugging her tightly against him – to the point that her huge breasts splurged from the sides of his wide silhouette. Akeno hugged him back, almost failing to hold her hands together due to the size of his lats.

"Khhhh! Ghhh…!" It did not seem to have been a conscious action. Marcus' body had moved on its own due to excruciating pleasure.

Even so, that small moment made Issei lose all pity for Marcus.

He was ENJOYING being dominated by Akeno. 'He has to be…! This piece of shit is more than big enough to take control of all of them if he wants to…! He has a sick fetish and is letting them take advantage of him on purpose…! Marcus isn't a victim. He's a pervert…! He's using his semen on purpose to ruin their minds and bodies…! I just know it…!'

The truth was convenient for Issei. If Marcus had turned out to be a simple good guy, that would make it harder to hate and judge him. Thankfully, such was not the case.

Akeno was the victim; Marcus the perpetrator.

Issei convinced himself of that even as his eyes connected with Akeno.

Issei convinced himself of that even as his eyes noticed Akeno's wide, wicked grin and squint.

Issei convinced himself of that even as Akeno took her cell phone from the side of the bed and took a selfie of the action.

Issei convinced himself of that even as he closed the door and noticed a strong hard-on in his pants.

THUMP! THUMP! THUMP! THUMP!

He did not think of it.

Everything was Marcus' fault, so there was no need to waste time thinking about why he was hard.

…

'Ah, it's because… I want to sleep with President tonight… Yes, that's why.' He thought about it anyway. 'I'll sleep with her and then… Talk to her about how we need to do something about Marcus. Things can't go on like this anymore…'

Indeed, they could not.

…Issei could not handle a single second more watching the women around him melt in pleasure that he could never match.

THUMP! THUMP! THUMP! THUMP!

…

THUMP! THUMP! THUMP! THUMP!

…

THUMP! THUMP! THUMP! THUMP!

Issei moved his hand to open the door to Akeno's bedroom again-

"Oh, hey, Issei."

"Wha-?!" Issei backed away and looked at the man who called him.

"What are you doing?" It was Kiba.

"A-ah, hey… I was just coming back from the bathroom."

"Ah, okay. I'm heading to the kitchen."

"Y-yeah! Yeah, I'm on my way back too!" Issei ran back to his bedroom.

At what point had he slid a hand into his pants to masturbate?

What had he almost done?

"President? What are you looking at…?" Issei asked Rias after entering the bedroom. 'She's staring at something on her phone… What is it…?'

"Heh?! Ah, Issei! I didn't see you come in…!" She threw the phone away. "It's nothing!"

"Sorry that I took a while. It's because… Uhm… Nevermind. We can talk about it later." Issei did not want to waste his erection; Akeno could be talked about afterward. "I was thinking… Why don't we-"

"Why don't we have sex tonight?!" Rias asked with a big smile.

"Yes! That's exactly what I was going to say. It's been a while so…"

"Yes, it's been, so come on…!" Rias lied on the bed and removed her lingerie, exposing her large breasts to him; Her body was slightly sweaty. "I know you love these, so come play with them… I can tell you want to." She took note of the bulge in his pants.

Meanwhile, Issei took note of the wetness between her legs and the erection of her nipples.

Rias was aroused by the prospect of sex with him to the point of being the wettest she had ever been before.

Issei's worries about her falling out of love with him were entirely unfounded. Rias was more excited than ever from missing him so much.

"Heh heh heh heh…" That was exactly what Issei needed to relax and play with her boobs, laughing like an idiot.

The sex they had that night was their best yet. Issei could see that Rias really enjoyed it, moaning more intensely than she usually did – even if not as loudly as she moaned with Marcus in that equipment room.

"I love you, Issei…"

"I love you too."

They renewed their love for each other.

Because of that, he felt nothing was wrong when Rias took her phone to go to the bathroom.

'Oh, yeah… Why did Akeno take that selfie? She didn't send it to me…'

He did not think too much about it.

It was the worst sex of Rias' life.

'I didn't feel a thing… Was Issei always this small…? I didn't get even close to cumming… Ghhh… There's no doubt about it now. I've been at least a little corrupted, even though I am a High-Class Devil. No woman can take that much cum from that awesome big black cock and come out unscathed…'

Rias had been dealing with intrusive thoughts of desire for Marcus every single day. Because of her self-awareness, she had managed to maintain control of herself with no major problems… Even if she had been masturbating to thoughts about Marcus before Issei arrived. 'That's why I was so wet… My vagina is throbbing. It wants to be filled and stretched like crazy… I don't think Issei can satisfy me ever again until I have a cure…'

…

What cure?

That was just a short-term lie that she told Issei without much forethought.

Asking Sona to look into it was just a panicked decision that would yield no results.

'That's wrong… She's going to figure something out, I know it…!' Rias was fueled by hope.

An important, essential hope.

One that allowed her to ignore what she was doing right now because all mistakes would be washed away once things got back to normal.

Rias was going to Akeno's bedroom to peek.

…The photo that Akeno sent her had enticed her…

…Seeing Xenovia, Koneko, and Akeno enjoying hardcore, pleasureful sex made her desire it too…

…Since she was a little corrupted and it was inevitable, it was okay to give in a little bit…

She would just watch.

Not go in, of course.

…Just watch-

"Oh, hey, Rias." Kiba greeted her.

"A-ah, hi, Kiba…" Rias ran into Kiba, who was checking something on his phone right by Akeno's door. "What are you doing?"

"I'm just going to the kitchen for a snack. What about you?"

"Me? Ah… I am…" Rias looked at the door. "I am going to the bathroom."

"Alright. Have a good night."

"Good night…" Rias walked past Akeno's bedroom. 'I can't peek with Kiba there…! Ghh… Whatever, this is for the best…!' Instead of waiting for Kiba to leave, Rias rushed on to the bathroom, taking control of herself. 'I can't give in this easily…! Peeking like a pervert is too much…!'

Indeed, Rias could not peek like a pervert.

She had to do better than that; Fight the urges in her body.

"Nghhhhh …" So, she merely masturbated in the bathroom, looking at the selfie Akeno sent her, thinking of the big black cock that could have been inside her at that very moment.

That barely counted as losing control, right?

Everything was in control.

Rias was in control of herself and of the peerage.

It was just a matter of time until Sona came with a miracle to save the situation.

"Ghnnnn !" Rias came too.

…Again and again…

It was fine to give in a little bit.

Things could not spiral that much more, surely.

Everything was under control.

"You're… What?" Rias asked, shocked.

"Oh, my, didn't you hear me? Then, let me say it again…" Akeno hugged Marcus from behind, squeezing his head between her breasts. She had grown tall enough that her chest could reach his head as long as he was sitting down – such as now, during breakfast. "We're a quadrouple now!" She laughed and smiled.

"…" Issei was as shocked as Rias.

Still, they did not ask any questions; Kiba and Asia did not too.

How could they?

"Ghnmmm … Mnghmmmm …" They were visually freaked out by Koneko, who was glued to Marcus' side with her nose buried in his armpit, sniffing like her life depended on it as she quivered and gushed juices on the floor, and her tail and cat ears twitched…

"GHLRGH ! BHLRGH ! SHLRRP !" …And audibly freaked out by Xenovia, who sat on Marcus' other side but had her face hidden under the table, sloppily and manically blowing him with passion.

"Oh, my! Issei, why are you looking at me that way? Ah… I think I know why…" Akeno squinted and giggled. "You wanted to be the 'Harem King', right? But maybe you won't be able to… The most you got was a throuple with me and Rias after a ton of work… Meanwhile, Marcus did nothing and has a quadrouple . Maybe HE will be the 'Harem King'. But… In his case…"

SNIFF…! SNIFF…!

"Mnghhmm … Nghmmmm …"

SPLAT! SPLAT! SPLAT!

"BHLRGH ! GHLRGH ! SHLRRRP !"

"…I guess he'd be the 'Harem Black King' ." Akeno laughed hard at her own joke.

Things had spiraled far, far beyond Rias' control.

"Oh, my! By the way, I should tell everyone that Rias is on course to find a cure for Marcus' curse…" Both in her peerage…

'He's so masculine… If he manned up a little more, I'd just let him take me from Issei right now… ! Fuck me too, Marcus …' …And in her heart.

Chapter 3: Rias Had A Duty - Part 1

Chapter Text

Issei never told Rias his worries about Akeno's behavior several nights ago.

After they finally had sex – great sex – he worried about ruining the mood of their relationship.

Moreover, if it was simply a matter of time until Rias finished sorting out a cure – whatever that meant – there was no reason for him to weigh her down with his worries. The last thing he wanted was for Rias to slow down her progress to do something about Akeno's steadfast corruption.

The best support he could offer was to remain tough, express no anxiety or concern, and let Rias and Akeno do their thing.

Once a cure was ready, everything would return to absolute normal. It would be like nothing happened at all.

…

'I still can't ignore it, though…' His mind kept coming back to the encounter with Akeno in the hallway several nights ago. 'Akeno looks really altered by the curse… Can she come back to normal…? Of course, right…? Rias says so, so it's gotta be true…'

…

'It just… Sounds really hard to believe in… I can't imagine it…'

…

'Why did Akeno say Rias is lying to me about something…? What could it be…?' Issei glanced to his side.

Rias was sitting beside him on the bleachers as they watched the volleyball game.

Issei considered asking her about the supposed 'lie' multiple times but never did.

Rias looked increasingly stressed and unfocused as the days went by.

No doubt, it was because of the cure she worked on… Though Issei knew nothing about it.

She never told him anything despite his questions.

No one was even supposed to know about it until Akeno exposed its development to the whole peerage several mornings ago, when she announced Xenovia and Koneko were now part of a quadrouple with her and Marcus.

'That's right… She must know something is wrong with Akeno based purely on that. I really have nothing I can do to help other than keeping quiet and letting things happen. Rias knows what she's doing. Everything will end up fine.'

Issei deposited his trust in Rias.

He was sure that, even now, she was thinking about how to solve things.

After all, she kept glancing at Marcus.

'He's got such a fat cock…! It's so fat and long…! And his body is incredible and strong…! I bet he'd make me cum my brains out if I let him do me right now… !' Rias kept glancing at Marcus and fantasizing about being crushed underneath him on a bed, pounded into orgasmic madness.

Alas, there must have been a misunderstanding about the Black King curse.

One did not require contact with the piece's semen or sexual contact to become corrupted over time.

It was the only way to explain the loss of control in Rias' own mind.

'…I wanna get home and masturbate…! Masturbate…!'

Rias touched herself to Akeno's photos every day, multiple times a day. Her queen piece had created the malicious habit of regularly sending her visual candy of Marcus' incredible body and sexual dominance.

Fucking Xenovia's face;

Getting his balls and asshole serviced by Koneko;

Brutally pounding Akeno's pussy or tits;

Their bodies soaked in cum;

Just his shirtless, sweaty body bulging with muscles with veins;

Akeno regularly sent her eye candy, and Rias regularly consumed said eye candy.

The more she masturbated, the more intrusive thoughts invaded her mind. She tried to battle them away and regain focus, but it was increasingly difficult. The only way to clear her mind was to masturbate them away.

'…I could just let him stick it in me… Stretch me out… Fill me up to the brim with cum… !' Her breathing accelerated just thinking about it.

PEEEEEEEEEEEEEEP!

The referee's whistle snapped Rias back to reality, making her look at the volleyball match once more.

It was another score for their school's team.

…The tenth in a row by their server, Xenovia.

"WOOOOOOOOOOOOH!" Xenovia celebrated by throwing her head back, shouting at the sky, and holding her fists in front of her midsection.

…Her ripped, veiny, bulging eight-pack midsection.

It was not the only ripped, veiny, and bulging part of her body.

Over the past few days, Xenovia had grown to an obscene 6'4" of height, packing full, veiny muscles all throughout her body. Her entire wardrobe had to be changed twice thanks to her continued growth not just in terms of height but sheer muscle mass.

She no longer looked like a mini-bodybuilder. Rather, she now looked like a full-on bodybuilder, reaching the limits of what a woman could look like without steroids.

…Most likely, past that natural limit by now…

Because her breasts kept up with her growth, looking increasingly fuller, rounder, and heavier, she maintained a curvy, feminine, attractive figure – pornographically so, with her clothes being so form-fitting that her red legging shorts dug into her huge asscheeks and gave her a 24/7 cameltoe. Her hips also widened beyond their natural bone structure, enhancing her curviness even further.

Similarly, her cropped tops always dug into her cleavage and smashed her nipples whether she used a bra or not. On the other hand, her arms were always exposed through the use of sleeveless clothing, letting everyone see her round shoulders, thick arms, and overall veininess.

Because of Xenovia, some schoolgirls might have discovered they were secretly lesbians all along.

Some schoolboys might have discovered they were secretly into muscle girls all along.

And, some people might have discovered they were just freaks all along.

It was the only thing someone could be if they looked at Xenovia's face and did not feel instant discomfort.

"Nexd boind! Nexd boind!" Xenovia shouted with a raspy voice for her team before clearing her throat. "Next point! Next point!" She corrected herself with the same raspy voice.

…Her lips had become abhorrently pillowy. So much so that she sometimes enunciated words incorrectly if she spoke too quickly because they flapped together mid-pronunciation.

As for the ever-present raspiness in her voice, there was a twofold reason.

Firstly, the obvious one: Xenovia regularly impaled her throat with Marcus' massive black cock, chugging load after load with junkie enthusiasm.

Secondly: Xenovia now wore a full-time leather buckle choker on her neck and buckled it as tightly as possible all day long so she could always feel strangled.

'Her oral fixation is so disconcerting… Her neck is a little veiny even now, and she gets breathless every now and then out of nowhere. Khh…'

If Xenovia was the sports pride of the peerage thanks to her INDECENTLY enhanced physique, Akeno was the opposite.

The sports shame.

Rias observed as Akeno gritted her teeth and grimaced openly throughout the whole match, frustrated that she could barely play properly.

Her breasts had grown too big.

If Xenovia's growth was muscle-based, Akeno's was chest-based.

Her entire figure expanded, giving her increasingly exaggerated wider hips, meatier thighs, and a rounder ass. That said, her breasts DEFINITELY grew at a greater rate than her lower body.

They were now the size of a volleyball and a half each.

Rias knew because she could visually compare it to the actual volleyball being served by Xenovia at that very moment.

"Grrr…" Akeno growled to herself in the court.

Her breasts were way, way too big. They got in the way of her receiving, spiking, setting, and overall movement. Not only did they bounce far too much with each step she took, but their weight hurt her back.

For Akeno, who loved volleyball and was a dedicated player of the team, it must have been insulting to become the worst player in the school so quickly and abruptly.

Still, Rias wondered how much Akeno truly minded her massively grown tits.

After all, she wore a pornographically undersized and overstretched cropped tank top that was held in place by nothing but her nipples, leaving her cleavage fully bare… Along with the dozens of bite marks and slap marks on it. Her red legging shorts were also excessively tight, leaving her cameltoe and ass crack constantly teased due to the fabric sinking into it.

Whereas Xenovia dressed pornographically out of carefreeness, Akeno did the same on purpose.

Did she flaunt her body to spite Rias? To seduce Marcus? To provoke Issei? To show some perverted form of dominance?

Rias had no idea.

'At least Koneko hasn't lost her mind… Right…?' Rias looked at Koneko, who sat beside Marcus on the seat below hers.

Koneko now wore a hoodie and baggy sweatpants at all times to cover her ears and tail, which she had lost the ability to hide for some reason. Not just that, but the latter had grown substantially longer.

'At least her body isn't freaking everyone out. Akeno and Xenovia are blatant… Everyone's looking at them and asking in their heads "what the hell is going on?"… Koneko looks normal to everyone else.'

Koneko did look normal.

SNIFF…! SNIFF…!

…But did not behave normal.

It was not normal to shove her face under Marcus' armpit in public and sniff loudly and uncontrollably while quivering in place as juices stained her sweatpants from the inside.

'Stand up to her, Marcus…! Don't let her do this to you in public…! It's weeeeeird…!'

Marcus did not stand up to Koneko.

He never stood up to anyone.

As the days passed, Rias felt more and more guilty for leaving Marcus to Akeno, who shamelessly and selfishly used him for her own sexual satisfaction – and to hurt Rias. 'She feels jealous about me and Issei and is sabotaging the peerage to hurt me…! And I can't do anything, or she'll tell everyone that I lied about a cure. I'm stuck… All I can do is passively watch…'

…

'No, I have to do SOMETHING!' Rias pumped herself up.

At the very least, she had to protect Marcus a little bit.

"Koneko…!" Rias whispered.

Koneko pulled back from Marcus' armpit and looked back at Rias.

"Stop. Not in public, okay…?"

"…I'm her girlfriend. You're not. Get over it, Rias." Koneko's bizarrely long tongue popped out as she spoke.

"Hah?"

"Akeno knows you're jealous of her, but Marcus is our boyfriend now. It is what it is."

"I'm your master! And I'm not jealous!"

"…Whatever." Koneko returned to Marcus' armpit.

It was the first time Rias was boldly and openly disobeyed by someone in her peerage.

"Marcus…! Don't let her do this to you in public!" Rias commanded him.

"A-ah… Uhm… Hm." Marcus also ignored her.

Most likely, he feared Akeno far more than he was loyal to Rias.

She could understand why.

…Akeno had grown deranged, arrogant, and sadistic…

Even though Rias spoke little with her since they swapped places, she could tell.

Akeno likely abused Marcus behind closed doors, using his body for her own selfish reasons, along with intentionally stimulating Xenovia's and Koneko's corruptions to hurt Rias.

'He has the body to stand up to her, but not the mind… I really abandoned him, didn't I…? What do I do…? Ah… I guess there's no way around it… I'll just have to explain it to Issei and get back to letting Marcus dump my pussy full of thick cum …'

…

'What am I thinking?! Khh… I won't let these intrusive thoughts win…!' The intrusive thoughts planted in her mind by the curse grew more frequent and powerful over time.

Sometimes, she almost thought they were her own normal thoughts!

'I need to talk to Sona…! I'm not going to wait anymore! After this game is over, I'm going to the Student Council Room and figuring something out with her- Woah!' Rias' thoughts were cut off by the impressive play taking place in the court.

For once, the other team managed to receive Xenovia's serve – though the poor girl who did it now had a huge bruise on her forearms.

Then, the ball was spiked back and received by a girl on Akeno's team.

The setter gave Akeno the best set Rias had seen in a long time.

It was perfect for her to spike and score!

Akeno jumped and…

MISS!

'Ah… She… Just missed it…' Rias cringed, along with everyone else.

She could not see or hit the ball properly thanks to her HUMONGOUS breasts getting in the way.

The shame and anger on her face after someone else saved the ball in the last second was a source of public embarrassment to all.

A moment later, the other school's team spiked the ball back.

Akeno moved to receive and…

BOING!

'A-ah… Her… Boobs…' Rias cringed again, along with everyone else.

Akeno not only failed to move nimbly enough to receive the ball with her arms but also accidentally received it with her boobs, making them shake and bounce off her top.

Everyone saw her nipples for a second before she hurriedly hid them back under her top – hurriedly enough that she accidentally did not adjust its bunched-up hemline enough, resulting in her excessive underboobs being on display for everyone.

It was a horrible receive. No one would be able to-

"I got it!" Xenovia sprinted with surreal speed, jumped higher than anyone thought possible, and…

SPIKE!

…Destroyed a poor girl's arm with an unrestrained spike, making the ball bounce out of bounds into another score.

It was her 13th score in a row. Xenovia was winning the game on her own thanks to her enhanced athleticism.

'D-did she completely forget we're supposed to act normal when we're playing sports with normal people…?! Xenovia, are you drunk on your muscles?!'

"WOOOOOOOOOOOOOOOOOOOH! Good one, eberyone!" She cleared her throat. "Good one, everyone."

Whereas Xenovia – and her astonished teammates – celebrated…

"Grrrrr…!" Akeno grew increasingly frustrated and angry.

Right before Xenovia served again, Akeno threw her a glance.

Xenovia got nervous.

Her next serve, she intentionally hit the net, finally letting the other team serve.

Akeno's team received the serve with ease and scored back.

Thus, her team rotated… And Akeno was the one rotated out.

Instead of waiting in place to be rotated back into the court, Akeno walked up the bleachers toward Marcus.

Her gigantic breasts swung and bounced with each step, along with her pornographically-meaty asscheeks.

Everyone looked at her the entire time; Men and women.

"Let me sit beside my boyfriend, please." Akeno told the girl sitting on Marcus' other side.

The girl scooted to the side.

"…More. I'm a big girl, aren't you able to tell? Since all you do is stare at my FAT tits, I expected you to know. MOVE MORE."

The girl scooted a LOT to the side, terrified.

"Petite little bitch…" Akeno sat down, still berating the girl. "So what if I have HUGE, USELESS tits or a HUGE, FAT ass?! I'm not worthy of respect anymore?! Is that what you mean?! I can't sit with the normal girls anymore?! JUST BECAUSE THEY GET IN THE WAY A LITTLE?! YOU SHOULD BE JEALOUS! LOOK AT MY BOYFRIEND! HE'S AS BIG AS MY BOOBS! HE FUCKS THEM RIGHT! THAT'S WHY THEY'RE THIS SIZE! YOU WOULDN'T KNOW! IF HE EVER FUCKED YOU, HE'D FIND YOU LACKING!"

The girl got up and ran away crying.

"That's right. Go cry in a corner with your tiny little chest… You're the freak, not me…" Akeno whispered to herself… And then turned to Marcus with a big smile. "Sorry you had to see that! People just have no manners nowadays. Did you miss me? How'd I do?"

"Y-yes. You did great. G-good job." Marcus answered with difficulty making eye contact with her; Koneko continued to sniff his armpit on the other side.

"No, I didn't. I played horribly. I have tits bigger than the ball because you can't stop dumping cum in me and ruining my body. Why do you lie to me? Is it because you're so in love with me that you can't help but be overly protective of my feelings? That's it, isn't it? I love knowing that you feel that way about me."

"Yes… Yes, that's true, Master." Marcus appeased her.

"Oh, that's good… I wouldn't want to think you're mocking me because you hate my fat tits. That'd really hurt me, since I'm only okay with these because you love kneading and slapping them so much when you pound me like a dumb little slut in bed."

"Y-… Yes."

"Yes, what?"

"I love slapping your big tits…"

"…Then why aren't you doing that now?"

"H-hm…?"

"Slap them. Look at my cleavage hanging out for everyone to stare at. Aren't you supposed to be using them? Hit the shit out of them right now if you really love me as your girlf-"

SNIFFFFF…!

Koneko accidentally cut Akeno off with a loud, vigorous sniff of Marcus' armpit.

"Koneko! Get the fuck outta there when I'm talking to my boyfriend!"

SMACK!

Akeno reached around and slapped Koneko on the face, forcing her to back off.

"I'm his girlfriend too." She defended herself.

"I am MORE girlfriend than you, so I get priority. Keep your disgusting tongue in your mouth and wait until it's your turn. It's always ME if ME is available. Filthy cat girl with tiny tits… Pfft."

Koneko silently accepted the treatment.

Rias considered saying something but worried about the consequences of antagonizing Akeno. 'If I piss her off, she might expose the truth to Issei right here… Tch… I can't believe I'm just watching Marcus suffer like this…! I need to do something…!'

…

'I could solve everything by becoming his dedicated cum dumpster again …'

…

'Control yourseeeeeeelf!!!'

"Marcus? What are you waiting for?" Akeno perked her enormous chest out. "Use them."

"W-we're in public…"

"So fucking WHAT?! Everyone is ALWAYS staring at these already! Didn't you see how everyone looked at me when I walked up here?! I can't hide these back-hurting monster tits from anyone, so why are you acting like it makes a difference?! Hypocrite! It's not like you hide this monster cock either!" Akeno slid a hand into Marcus' pants.

STROKE! STROKE! STROKE! STROKE! STROKE!

"Ghh…!"

Akeno pulled her hand back and showed Marcus her precum-soaked hand; The substance was so strong that even Rias could smell it. "See?! See?! You LOVE my MONSTER tits so much that you walk around with a MONSTER black cock for everyone to look at! Stop acting coy and MAUL these UGLY, WORTHLESS chest bags like you do EVERY night!"

Marcus cringed… And then raised his hand.

SMACK!

"Ooh !"

SMACK!

"Ngh !"

SMACK!

"Ungh !"

He did exactly as she asked, beating down her tits with an open palm again and again in public. The strikes were so impactful and her boobs shook so exaggeratedly that it took less than a minute before everyone around them started staring at the visual spectacle.

That did not mean he stopped slapping. Marcus certainly wanted to stop, dying of shame, but Akeno had a greater hold over him than simple public shame.

He struck her tits HARD and MERCILESSLY again and again, only willing to stop once she ordered him to.

That would likely take a while.

SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK!

"Ngh ! Ooh ! Hoh ! Mngh ! Ungh ! Ghn Ughn ! Khn !" Akeno rolled her eyes, bit her lips, and groaned with each strike, trembling in pain-induced orgasm.

A weird mix of masochism and sadism. Akeno regularly demanded for Marcus to abuse her body yet was the one in control at all moments.

Rias endured an uncomfortable and shameful mixture of emotions.

Pity for Marcus;

Guilt over her inability to act;

…Arousal and envy, wishing she were the one getting her tits slapped silly…

'His hands are so big … His muscles are awesome … Look at the huge bulge in his pants … Please, slap my tits while you push your cock really deep inside my womb … Please, please, fill it with lots of cum …'

Beside her, Issei avoided looking at Akeno, uncomfortable.

Asia, too.

Kiba looked with no issues and crossed legs, seemingly disinterested.

…And everyone around them stared with a mix of public discomfort, curiosity, and arousal…

"What is it…?! Mngh… ! You all act like you haven't…! Nghh… ! Stared at my tits ALL this time…! Oooh… ! My boyfriend is a horny… ! Ungh… ! Black man ! That's just how things are between us! He SLAPS and FUCKS these tits ALL the time!" Akeno bemoaned everyone around her with a raised voice, grinning.

Her mind was deeply warped by the curse.

"Aaaah, fuck, fuck, fuck… ! I'm cumming… ! Nghhhhh !!!" She clenched her teeth, rolled her eyes, and pumped a load of pussy juice into her shorts, much of which seeped through the fabric and puddled up on the ground. "Hah … Hah … Having ugly, gross, fat tits is the best … You can stop playing with these now, Marcus."

"Y-yes, Master…"

"Haaaah? You don't look that satisfied. Could it be that you didn't like it? That's not possible. HUGE, ANNOYING Asian tits exist to be toyed with by big black hunks like you. No way, no way, no way. You don't mean that these gross bags on my chest aren't good enough for you, do you? Do they need to be bigger?! Didn't I let you FUCK them enough last night?!"

Marcus had no idea what to say.

Nothing would satisfy her.

Though Akeno spoke with the usual cocky smirk on her face, her personality had completely lost its cool, replaced by an endlessly pissed-off sadist.

"Rias, can you believe this guy?" Akeno turned around to address her. The nipples on her chest protruded to a bizarre degree; Her cleavage was marked with bruises and sweat from the public assault dished out by Marcus. "I don't even know if it's because of this guy's Black King curse. I think he's just a horny black boy who likes demanding more and more."

"…"

"You've got nothing to say…? I guess you don't really think about Marcus all that much, huh? You're too busy being happy with Issei. It's the same for you, isn't it, Issei? I bet you don't even miss me. Rias is all you need, huh…?" Akeno's usual smirk was replaced by a condescending stare. "That's okay. I'm plenty satisfied with Marcus' big black cock drilling me out. I bet I'll be packed with mixed babies any day now. Would it hurt you if he knocked me up? That'd really put a dent in your Harem King plans, huh-"

"Akeno, stop it." Rias spoke up.

It was a simple, straightforward command said with a calm, authoritarian voice.

"…Hoh. Do you really have the time to give me orders, Rias? Why are you even here? Shouldn't you be working on that cure…?" Akeno provoked Rias.

An obvious threat: If annoyed too much, she would expose Rias to Issei.

"Akeno…! You-"

"Stop it, Akeno! Why are you doing this?! You're being mean to everyone!" A girlish, high-pitched voice cut them all off.

It was Asia, shouting with a nervous blush on her face.

Everyone stared at her with surprised looks, not expecting Asia, of all people, to rise up against an unhinged Akeno.

"Asia…" Akeno muttered before transitioning from surprised to angry and cocky. "…You're too pure to understand. It's easy for you, isn't it…? The 'cute girl' look makes it so little perverts like Issei give you all the attention… Maybe you should quit being so pure … Why don't you, I, and Marcus go for a-"

RUB! RUB! RUB!

"H-hey…!" Akeno was again cut off; This time, by a deranged Koneko rubbing her face on her precum-soaked palm. "Back off…! Back off…!"

Koneko did not back off.

Did she even know what she was doing, or heard Akeno?

"Ghnmmmmmmmm …" Based on Koneko's groaning and quivering, it was more likely that she lost herself in orgasm from feeling Marcus' precum on her skin.

"Annoying slut…!"

SMACK!

Akeno slapped Koneko away – not that she cared, still quivering with rolled-up eyes.

Akeno.

Xenovia.

Koneko.

They had turned into sex freaks because of the Black King curse.

Rias had made a colossal mistake in swapping places with Akeno.

'I said there was a cure as a short-term lie, but now it needs to be true…! I need to talk to Sona as soon as this game is over…!'

PEEEEEEEEEEEEEEEEEEEEEEEEEEP!!!

As if on cue, the match ended.

Akeno's team did not lose a single point after she got rotated out.

Xenovia was an athletic monster who received, blocked, and spiked every ball with supernatural ease.

"WOOOOOOOOOOOOOOOOOOOOOOH!!!" She shouted in celebration again… "Ooops!" …Accidentally ripping parts of her cropped tank top and legging shorts due to her muscles.

Akeno stared at Xenovia, annoyed. "Game over, huh…? They didn't lose a single point after I got rotated out… How nice of us to have Xenovia on the team, making up for my annoying tits…" She paused and smirked. "Marcus, your cock needs some milking, doesn't it? We wouldn't want you having an episode." She sank her nails on his veiny forearm. "Let's go behind the courtyard bathroom building over there. You too, Koneko."

With that, the altercation on the bleachers ended.

Akeno, Koneko, and Marcus left.

Akeno with her monstrosity of an ass and chest bouncing with each step, pushing her team tank top and shorts to the limits;

Koneko with her hand glued to her face, sniffing precum endlessly;

Marcus with hunched shoulders and an uneasy look.

Xenovia also followed along after Akeno gestured to her.

By now, everyone at the school knew they were in some sort of hardcore sex quadrouple. That said, only Rias and her peerage knew that Akeno was an authoritarian freak who commanded the other three members of the quadrouple.

"P-President…" Issei whispered to Rias.

"Hm…?"

"About that cure… Is it gonna take much longer?"

"N-no. It won't."

"How… How does it work? What are you doing, exactly…?"

"It's not me. Sona is the one making it." Rias caved and offered some 'information'.

"Oh, okay… I see… And it'll bring Akeno back to normal…? And Koneko and Xenovia?"

"Yes! Totally! I promise!" It was a lie, but Rias wanted it to be true.

She wanted to be brought back too.

'Stick it in me … Stick it in me …' …Because she felt her mind slipping more and more. 'Hm…? What's happening there…?'

Before Akeno and her group could make it to the bathroom, Sona cut them off with crossed arms.

She looked at Marcus and opened her mouth…

…

…And then said nothing and left.

Rias did not understand what that was all about, but it did not matter! It was as perfect of a moment for her to go talk to her and find out if she discovered anything in her research.

"I'll be right back." Rias got up and ran toward Sona.

Toward Sona!

Toward Sona…!

Toward…

'Ah… This is the worst… The curse has taken too much control of me…!' Rias did not run toward Sona.

She ran toward the courtyard bathroom building.

Her intrusive thoughts turned into intrusive actions.

She wanted to see what they were about to do!

Watch from up-close!

…Masturbate to it…

'I-it's good that I learn a little bit about how Akeno is treating Marcus behind closed doors too!' She invented excuses in her mind.

The quadrouple did not enter THE bathroom building. Instead, they went around it to fuck behind it.

That gave Rias the privileged opportunity to spy from within one of the stalls of the bathroom.

Their school's principal was a creep. Each stall had a window to allow sunlight to come into the bathroom; However, the window was heavily tinted, making it impossible for anyone to look in from the outside. Regardless, it still made that bathroom very uncomfortable for any girl to use, which is why no one ever did.

…But it was perfect for Rias to look at what was happening outside without being caught.

Indeed, Akeno had gone deranged thanks to the accelerated corruption caused by being pumped so full of Marcus' cum on a daily basis.

It was the only way to explain the way she treated others.

"GHLRGH ! BLRGH ! SHLRRRRRP !" …Such as Xenovia, who was currently on her knees, being forcefully made to facefuck the nude Marcus' ENORMOUS, VEINY black cock with Akeno's hand on the back of her head, slamming her back and forth without any mercy.

"Did you have fun, Xenovia…? Was it nice to have everyone's eyes on your amazing volleyball skills? You carried the team all by yourself! Oh, my! Congratulations, congratulations…!" Akeno spoke with the same playful sarcasm and smirk that was so characteristic of her.

The vein on her forehead and lack of restraint on her actions directly contrasted with said 'playfulness'.

SCHLURGE! SCHLURGE! SCHLURGE!

"BHLRGHHHHH ! GHLUUUUUURGH !" Xenovia might not have been able to hear Akeno in the first place. Her face was a deep shade of red, and her eyes were rolled up with endless tears pouring down her cheeks. Moreover, her disconcertingly thick lips were swamped with spit bubbles and precum.

"Here you go, here you go. This is your reward for being everyone's volleyball queen! Oh, my… And to think *I'm* the queen piece! But not when it comes to the sport I loved playing so much before I got these HORRIBLE, GROSS, ANNOYING tits! That's you, Xenovia. Oh, my! Congratulations, congratulations! Have your prize in cum, please. Drink a load fitting for a REAL volleyball queen!"

SCHLURGE! SCHLURGE! SCHLURGE!

Despite Xenovia's creepy oral fixation, there was a degree of facial abuse that was too much even for her.

That degree was in front of Rias at that very moment: Facefucking so forceful that Xenovia's thickened lips FLATENNED and DUG into Marcus' crotch with each motion – not to speak of the harrowing stretching of her throat with an immense cock-shaped bulge. The buckle choker on her neck had not been unbuckled at all, resulting in even tighter constriction of her throat.

'She's pushing her too hard…! Akeno, you're losing yourself…!'

Xenovia's face was plastered with tension, oxygen deprivation, and veins. Every time her lips smashed against Marcus' crotch, a huge volume of saliva and precum splurged out of her mouth, puddling up in the bursting cleavage residing within her strained tank top. There was little room for any liquid to remain in her mouth – especially when she squeezed her cheeks so devotedly to provide Marcus' cock with the most stimulation possible.

'Ah… Look at him… Marcus' muscles are awesome…! I love how veiny and defined they are…! And his abs… I wanna lick them up…! Grind them against my tits, Marcus, please …' Rias slipped into intrusive thinking.

Even though Marcus was being vigorously serviced by Xenovia, he did not look happy, clearly uneasy about the situation.

The current encounter had nothing to do with keeping the curse sedated so he did not feel pain or have an episode. It was merely a form of Akeno punishing Xenovia for perceived unfairness thanks to her altered mental state.

'This is so rough… Akeno's going to break Xenovia's neck if this keeps up-'

"It's not working." Koneko said.

"Tch! I know!" Akeno let go of Xenovia's hair.

The moment she stopped taking charge of Xenovia's head…

SCHLURGE! SCHLURGE! SCHLURGE!

"GHLRGHH ! BHLRGHH ! GHLURGH !" …Nothing changed.

Rias' jaw dropped.

Akeno had not been abusing Xenovia's face whatsoever.

She had been TRYING to… Unsuccessfully.

SCHLURGE! SCHLURGE! SCHLURGE!

"BHLURGH ! BHLRGHH ! GHLRGHH !" Apparently, Rias' assessment of Xenovia's oral capabilities was entirely wrong. There was no degree of facial abuse that was too much for her, willingly destroying her own throat with plentiful enthusiasm. Her leather buckle choker QUAKED and STRAINED, threatening to snap at any moment thanks to the huge cock stretching out her neck.

"She's cumming again…" Koneko noted.

"Oh, my! You're excellent at pointing out the obvious! Congratulations, Koneko! Very impressive." Akeno pulled Koneko's hoodie back and petted her ears.

Her quivering ears.

Koneko, too, was cumming from staring wide-eyed at a naked, sweaty Marcus having his cock drained by Xenovia's enhanced throat and lips. The scent of his precum relentlessly oozing out thanks to the energetic deepthroat was enough to send her over the edge multiple times.

"GHHHHHHHH!!! KHHHHHHHHH!!!" Everyone's attention was captured by Marcus' abrupt roar, which was followed by ERRATIC spasms that lasted many, many seconds.

He was ejaculating… Or so Rias deduced.

It was not as if she got to see any semen to confirm that hypothesis.

"GHLRGHHHHHHHHHHHHHHHHHHHHH !!! SHLRRRRRRRRRRRRRRRRP !!!" Xenovia sank her fat lips into Marcus' crotch and left her tongue out of her mouth as a carpet to ensure not a single drop escaped her mouth. His entire load was poured straight down her throat, filling her stomach up. Her buckle choker TORE off thanks to Marcus' big black cock bulging excessively from cum-pumping spasms.

'S-… So powerful…" Rias admired the flailing of the cock bulge inside Xenovia's throat. Even though her neck squeezed HARD to pleasure his monster cock, it still thrashed maniacally, trying to break out. Her neck distended in bizarre, creepy ways as it fought to restrain the long beast firing cum deep inside it.

That said, Xenovia still took it like a champion…

"SCHLURGE! SCHLURGE! SCHLURGE!

"GHLRGH ! BHLRGH ! SHLRRRRRRP !" …And resumed facefucking him right after.

She was an oral freak.

"Tch…" Akeno was disappointed.

"Can I eat his ass now…? Or lick his balls…? Or lick his cock…? Or lick his sweaty abs…? Or sniff his-" Koneko stopped, leaving half her long tongue out of her mouth – it was hard to keep it inside whenever she was talking so much, which was why she kept mostly quiet.

Akeno had grabbed Koneko's small shoulder with a cold glance of suppressed fury.

Her patience was at its limit. If Koneko said a single word more, Akeno would lose it.

"I've been far too nice to the two of you." She said. "Naming you as his girlfriends along with me… You barely earned it. I'm the only one who actually puts in the work to keep his cock pleased. That's why I'm number one. Right, Marcus…?"

"Y-yes…! Master! Ghhh…" He spoke with difficulty thanks to Xenovia's ongoing relentless oral service.

"Oh, my… That's right… But I've been neglecting my duties to you… I mean, look at this…" Akeno grabbed Xenovia's shorts, pulling on them until Xenovia was bent over instead of squatting.

"SHLRRRP ! BHLRGH ! GHLRGH !" Xenovia was so immersed in sloppily facefucking Marcus that she did not notice Akeno touching her body. The only support she needed to keep going was her arms wrapped around Marcus' muscular lower body, ensuring she could thrust her head back and forth at maximum speed.

"She's got quite the ass now. So packed with muscle. Isn't it a little bit irresponsible that you haven't gotten to fuck it yet?" Akeno removed Xenovia's shorts, exposing her round, muscular rear.

"M-Master… I don't know if that's-"

"What, you think she can't take it? Look at how she's sucking you off this very instant. Xenovia can take anything."

"S-still-"

"Still what? You're not happy?" Akeno smiled wider. "Oh, my! Not only do I get you two sexy, slutty girlfriends to milk you like whores day in, day out, but I also let you FUCK the SHIT out of me EVERY SINGLE NIGHT. You slam, and slam, and SLAM into my womb; Make me scream; Make me cry; Slap my tits; Slap my ass; Choke me out; Make me pass out; Pump so much cum into me that it hurts but you don't mind it. You enjoy it. How come you can't do the same with Xenovia's butt a little bit? It's okay to hate-fuck ME but not HER? I mean less to you than the girl I BROUGHT you? I gave you a quadrouple and this is what I get in return? You don't love me even when I bring you lots of holes to keep your big black cock pleased?"

Rias was as freaked out by Akeno as Marcus.

It was no wonder that he so easily submitted to her. 'Akeno, are you completely gone…?! Khh…! I shouldn't have abandoned my duty…' Rias blamed herself for the colossal mistake she might never be able to fix.

Once she regained control over her intrusive thoughts and got out of there, she HAD to go speak to Sona.

Immediately!

"…" Marcus said nothing, horrified by Akeno's passive-aggression.

"Oh, my! You really aren't happy, are you, Marcus? I have not brought you enough holes yet. Xenovia, pull back."

"GHLRGH ! BHLRGH ! SHLRRRP-"

ZAP!

"Khyah!" Xenovia shot back from a sudden jolt of electricity coursing through her body – Akeno's doing. "Kuh! Kuh! Hah … Hah …" She coughed and panted, letting a big volume of semen pour down her chin. Even when taking his load deep into her throat, some remained in her mouth. "Wh-what is it?! I was really into it…!"

"We're changing positions. You're going to suck in a different way now."

"Ooooh. That sounds fun. Let's do it, then! My throat is still itching… I need some more… !"

"Marcus, last night's wall fuck, okay?"

"Y-yes." Marcus put Xenovia's back against the wall and raised her legs in the air by the kneepits. "Like this, right…?"

"That's right. I love how you remember the way you fucked me last night. That must mean you cherish our intimate moments together a lot."

"Y-yes, Master."

"Uh… How am I gonna suck him off in this position…?" Xenovia asked, not following what was about to happen.

"I never said you'd suck him with your mouth. Marcus, get your dick in place."

Marcus aligned his enormous, veiny, cum-soaked black cock with Xenovia's pussy.

"…Lower ." Akeno said with explicit malice.

He aligned his black cock with Xenovia's asshole.

"…Heh?" Xenovia muttered.

"Oh…" Koneko muttered.

"K-khh…" Marcus grunted.

"Oh, my…" Akeno giggled.

'She's gonna have him put it in her ass?! Is it Xenovia's first time with anything other than her mouth?! Won't she die?! Isn't Marcus too big for an anal virgin?! Or a complete virgin, for that matter?!'

"A-A-Akeno, I don't know if this is-"

"Don't worry. You've got a really muscly ass to buffer his thrusts. You can take it."

"A-a-ah… O-okay… Okay... You'll be gentle, right, Marcus…?"

"Yes, of course! You can trust me-"

"Shove it all the way in as hard as you can." Akeno cut him off with a grim, authoritarian tone.

Marcus grimaced for a split-second… And then obeyed.

PLAP!

What a thunderous moment.

Marcus really did it: His GIGANTIC black cock went all the way into Xenovia's virgin asshole in a single thrust, resulting in a MASSIVE cock-shaped protrusion in her shredded abs.

The TIGHT grip of Xenovia's anal entrance was an astounding sight of its own, twitching and squeezing around Marcus's hard shaft as if trying to brutally strangle it to death. The same MAD squeezing could be seen in her bulging abs, which popped with veins of physical exertion as it clamped against the cock bulge destroying their shape.

Koneko observed with parted lips, stunned.

Akeno grinned, sadistically pleased by the crude penetration.

Marcus had no opportunity to express his feelings through facial expression, instead forced to clench his teeth and contort his face as his HARD cock got CRUSHED by the rectum of an overly-muscular woman.

Rias was pale and stiff, in awe of what happened.

And Xenovia…

"…" …Made no sound, simply looking at her abs with wide eyes and a slightly open mouth.

Could it be that she felt nothing?

Perhaps she could take it better than anyone anticipated?

Or was it that her mind went haywire with the sensations of having her guts STRETCHED, HOLLOWED, and RESHAPED by Marcus' ruthless balls-deep penetration?

The latter.

Obviously, the latter.

That conclusion was made clear a mere few seconds later.

Sweat poured down Xenovia's figure.

Every muscle in her body contracted FIERCELY, coating itself in thick veins.

Her toes and fingers curled.

And then…

"WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOH !!!!!" Xenovia wailed with her tongue swinging madly outside her mouth, her eyes rolling up, and tears blasting down her cheeks.

"WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOH !!!!!" Her body convulsed in place, enduring orgasm so powerful that no one other than her could tell if it felt good or painful – most likely, both.

"WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOH !!!!!" The defined abs that had become so characteristic of her bodybuilder figure CLENCHED even harder, turning her midsection into a flesh condom that perfectly highlighted the outline of Marcus' huge cock – down to the veins.

Akeno giggled, smiling. "Oh, my… Just like when she scored. What a lovely, celebratory shout."

There was no smile on Xenovia's face. All she expressed through her scream was maniacal sexual ecstasy, drooling all over herself as her tongue and head thrashed hectically, struggling with the sensations overwhelming her brain and body.

Nevertheless, even though she howled for several seconds as her body convulsed, it did not mean she had reached peak pleasure.

That occurred after she stopped howling.

Rias saw it happen in slow motion.

Xenovia's neck tensed and contracted.

One of her eyes closed halfway, twitching.

Her wide-open mouth shut itself back into a small 'O' with only the tip of her tongue hanging out.

And then…

GUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUSH!!!

…A seemingly infinite hose of pussy juices blasted out of her unpenetrated pussyhole, showering Marcus' nude upper body, resulting in streams of the sticky fluid running down the crevices of his bulging eight-pack abs.

Back in the gym equipment room several days ago, Rias also enjoyed squirting orgasms as Marcus pounded her in a vigorous Nelson hold.

It was nothing like Xenovia's.

There was no end to hers.

The blast just kept shooting and shooting without cessation. No matter how much her pussy lips gaped, twitched, and squirmed, the hose kept firing and firing and firing.

"Oh, my…! Xenovia, isn't that too much of an anal orgasm for someone so obsessed with sucking cock?"

"!!!" Xenovia offered no comment, stiff with one eye rolled up and the other twitching halfway shut.

It was a pornographic, arousing sight… But also gruesome.

Her face turned redder and redder. All breathing ceased to be thanks to the extremely powerful orgasm ripping endlessly through her muscular body.

GUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSH!!!!!

"Khhhh…! Sh-should I pull out?"

"Why would you? She's enjoying it, isn't she?"

"B-but…"

"Stay inside her."

GUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSH!!!!!

'Xenovia needs a break…! She's going to run out of air at this rate…! It's too much…! Marcus' cock is just too powerful…!' Rias had an impending need to intervene.

…

RUB…! RUB…! RUB…!

"Ooh … Ghn … Ngh …" …But did nothing, instead rubbing her pussy as she continued to watch the grim sexual encounter.

The intrusive thoughts planted by the Black King curse won again. Otherwise, she would have acted right then.

'I'm sorry…! I'm sorry, Marcus…! I swear that I'm not like the girls taking advantage of you…! If I could, I'd help you, but I'm not in control of myself right now…! As soon as I can, I'll go talk to Sona and figure something out! As soon as I can…!' She begged for forgiveness, fervently rubbing off.

Eventually…

GUSHGUSHGUSHGUSHGUSHgushgushgushgushgushgush…

"…" …Xenovia's minutes-long squirting orgasm saw its end.

Her abdomen stopped contracting.

Her head collapsed forward, unconscious.

"Oh, my! That's all she could handle…? It wasn't that much of an orgasm…" Akeno boldly lied.

The liters of pussy juice running down Marcus' muscular front told a different story. Xenovia had orgasmed every drop of female fluid existent in her body. Even now, her skin was greasy and glistening with sweat, highlighting the veins and bulging of her muscles.

"Ghhh…! Should I pull out…! Now…?!"

"Pull out? You haven't even started fucking her."

"I-I can't…!"

"…Why not?"

"I-it's too tight! I can't even move…!"

"Hoh… Really…?" Akeno brought her face right beside Marcus', glaring wide-eyed at him. "…I'm offering you lots of great holes to fuck and you're going to hold out on me…? Don't you feel even slightly guilty that my tits got grossly big because of your cum…? At least appreciate the gifts I bring you as your number one girl… Do you think it's easy keeping your cock pleased?"

"I-I-I do appreciate it…! I just... I-I really can't move…!"

"Oh, my! But I want you to nut a lot more. What should I do, then…?"

"I can eat his ass!" Koneko cut in with her disgustingly long tongue licking the air "…And his balls too. Until he cums…"

"Go ahead then, Koneko. How helpful of you."

Koneko dropped to her knees, pulled Marcus's muscular asscheeks as far apart as she could, and buried her nose and tongue between them, sloppily licking his asshole up and down… And also the entire outline of his heavy low-hanging balls and some of Xenovia's asscrack.

Her tongue was that long.

"Shlrrrrrrp ! Shluuuurp ! Shloooorp !" …And that passionate and wet.

"Do you like it, Marcus…? Is it good to have your big black cock shoved into a tight, fit asshole while a petite little cat-bitch licks your ass and balls up with lots of spit?"

"Y-yes…! Thank you, Master…! Ghh…!"

"And she's quite enjoying it too…" Akeno observed Koneko.

So did Rias.

The cat girl's ears trembled nonstop, much like the tail restrained inside her baggy sweatpants, which flailed about so excitedly that it tore itself free. Much her like her tongue, it had also grown bizarrely longer – as long as her entire height.

It was not only her cat traits that expressed sexual ecstasy. Her pussy did too, hidden inside her sweatpants.

At least Rias assumed as much when she saw a puddle of thick pussy juice form between Koneko's feet.

The sweatpants never came off, but Koneko gushed so much female cum from eating Marcus' ass and balls that the fluids overwhelmed the fabric, leaking and dripping onto the ground.

'She's cumming just from licking his asshole…! That's… That's insane…! Koneko's body is completely broken by the curse too…! All three of them are…!'

…

'…Well, I get it… I ate his asshole once too… And… It was better than any sex I ever had with Issei … I wanna do it again… I wanna eat it just like that…' Rias had more and more trouble filtering the intrusion inside her head.

RUB…! RUB…! RUB…!

'Ah…! As soon as I can…! I'll go talk to Sona! I swear, I swear…! I'm not this vile and degenerate…! This is not me…!'

Akeno grabbed Marcus' shoulder. "As much as I appreciate Koneko's ass-eating, you won't cum just from this, will you, Marcus? I suppose I have to help. Oh, my! Being your favorite girl is so difficult… Black cocks are so, so needy."

Marcus almost opened his mouth to tell her he did not want her 'help'… But stopped, aware that it would just antagonize Akeno.

Everything just antagonized Akeno.

She had become a cesspool of negativity.

'What is she gonna do…?' Rias observed, confused.

Akeno touched Xenovia's abs with an index finger.

"What are you going to do…?"

"Since you can't thrust, it'll be hard for you to cum, won't it? Your cock needs lots of stimulation… I hope a little bit of wet, warm squeezing is enough."

"I don't… Uh… Understand…"

Akeno giggled maliciously, grinning. "I'm going to name this a gutjob, okay…? A form of sexual service invented by yours truly, on this day."

"A gutjob…? What…?"

ZAP!

"NGH !" Xenovia's head threw back as her body spasmed for a split-second, firing a quick jet of pussy juice against Marcus' abs. Then, her head collapsed forward again, maintaining the same unconscious look with one eye rolled up and the other shut halfway.

"GHH!" Marcus grunted as well.

Akeno had very briefly electrocuted Xenovia's ripped, sweaty abs, making them contract hard against Marcus' cock.

"Oh, my … It worked better than I expected. It's not as good as thrusting and scraping into a tight asshole, but it'll be enough to make you cum if I do it enough times, right?"

"H-h-hang on…! It might be too much for Ms. Xenovia…!"

"She can take it." Akeno dug her index finger into Xenovia's abs.

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

"NGH ! OOH ! HOH ! MNGH ! UGHN ! GHN ! KHHN ! UGHN !" …And gave Marcus a crazed, inhumane 'gutjob', making Xenovia blast dozens and dozens of new jets of pussy juice with each zap as unconscious groans came out of her mouth.

Marcus could do nothing other than clench his teeth and endure the cock-crushing contractions of Xenovia's immensely powerful abdomen; On some level, the electricity probably affected his cock as well, making it jerk inside Xenovia's tight rectum.

All the while…

"Shlrrrrrrrp ! Shluuuurp ! Shlrrrrrrp ! Shlooooorp !" …Koneko continuously bathed his asshole and balls in spit.

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

Akeno did not show an ounce of mercy, intermittently switching her gaze between Xenovia's miserable oxygen-deprived expression of vacant euphoria and Marcus' masculine grunts.

…She made eye contact with Rias…

'HUH?!' Rias pulled back for a quick second before realizing it was a mistake. 'H-hahahah… It just looked like she looked at me, but there's no way. This window can only be seen through from my side…'

"M-Master…! Ghhh…! Ms. Xenovia…! Needs to breathe…!" Marcus worried for Xenovia's well-being.

Her face was so red and veiny that it bordered on horror; No more sounds came out of her mouth due to excessive strain and sheer lack of air.

Anyone would worry.

"…Then you should nut faster." …Except for Akeno, whose malicious grin simply grew wider.

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

GUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSH!!!

"Come on, come on… Enjoy the gutjob and nut…"

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

GUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSH!!!

"Let her breathless guts squeeze your cock into shooting a juicy nut out…"

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

GUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSH!!!

"Don't hold back. Just because she's almost turning into an ACTUAL meathole doesn't mean you shouldn't shoot your delicious cum deep inside her."

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

GUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSH!!!

"Your main girl is asking for it, so you gotta make it count… Or are you going to waste mine and Xenovia's efforts? Look how much she's suffering for you."

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

GUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSHGUSH!!!

"If you really care about her, just shoot faster. Let it all out-"

"KHHHHHHHHHHHHH!!!" Marcus let out a loud roar.

He was about to ejaculate inside the DESPERATELY breathless and unconscious Xenovia.

"Out." Akeno removed her own cropped tank top.

"WHAT?! GHHHHHHH…!"

"Out! Out! Out! OUT! Pull OUT! Nut in my TITS!"

"I CAN'T…! IT'S…! TOO…! TIGHT-"

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

"OUT! PULL OUT!"

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

"YOUR CUM IS MINE! YOU'RE SUPPOSED TO CUM IN MY TITS WHENEVER THEY'RE AVAILABLE!"

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

"YOU SHOULDN'T HAVE EVEN SHOT THE FIRST LOAD IN HER THROAT! IT WAS MINE!"

ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP! ZAP!

"OUTOUTOUTOUTOUTOUTOUTOUTOUTOUTOUT-"

PULL!

"GRRRRRRRRRRRR!!!" Marcus successfully pulled out of Xenovia's asshole by pinning her shoulders against the wall and using his full strength to pull his hips back.

It was a sloppy, crude pullout.

Perhaps too sloppy and crude.

"WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOH !!!!!" Xenovia let out one last volleyball score wail before falling ass-first on the ground, unconscious with her back to the wall… And a prolapsed asshole.

GUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUSH!!!

…And offering a final, extensive spray of pussy juices.

"In my tits. IN MY TITS!" Akeno got on her knees and squeezed her nude boobs together.

"GRRRRRRR…!" Marcus aimed his cock at her tits-

"IN. I SAID IN! NOT ON! IN! ARE YOU STUPID?! DO YOU NOT SPEAK JAPANESE?! IDIOT!"

"K-KHHHHHH...!!!" He shoved his cock between her tits.

Not in a vertical angle, which would have left his tip and much of his shaft poking out of her cleavage to shoot at her face.

Rather, in a horizontal angle that kept his tip snugged deep between her humongous, oversized tits.

Because his cock was so absurdly long and thick, plenty of his shaft remained unembraced by her breasts, but it did not look like Akeno cared.

The mad, malevolent smile on her face told the whole story of her feelings.

…Unabated euphoria…

Feeling Marcus' vast load splattering all over the inside of her slap-bruised tits was a blissful sensation for any woman… And likely even more so for Akeno herself, whose body had been deeply tainted by the Black King curse.

Rias understood it well.

She had the marvelous experience of milking Marcus with her own huge tits on the rooftop of the school.

…Feeling his majestic black cock thrash and pump cum while her soft, warm chest hugged it was so, so good…

'I wanna give him a titjob right now … Right now … Ah… !' Rias removed her clothes to better touch herself, now also playing with her nipples and breasts.

RUB…! RUB…! RUB…!

PINCH…! KNEAD…!

"Fuuuuuuuuck … You shot a lot… That's it… My tits are so fucking sticky now … Good job nutting, Marcus. Aren't you happy…?" Akeno pulled back, keeping her tits squeezed by fisting their sides so no cum leaked from below.

"HAH…! HAH…! HAH…! HAH…! HAH…!" Marcus breathed raggedly.

"Aren't you happy?"

He looked down at her.

For a split-second, Rias saw raw fury on his face.

It scared her.

…It also turned her on…

"Y-yes… I'm happy. Thank you, Master…" The raw fury was quickly replaced by submissive timidity.

"Tch. Not happy enough. Look at the mess you just caused in my tits. They're fucking slimy. Look at this!" She mashed her tits together up and down, making them squelch and bubble with semen. "But I guess that's why you spermed me up into having these ugly, horrendous tits, isn't it? So you could use them as a cum depository. My body and image are ruined forever, but at least you get to have fun because you're a horny, virile black male. Poor you…"

"G-ghh…"

"Can I get back to eating his ass…?" Koneko asked with a heavy blush and a drooling tongue, interrupting what would have been another unhinged monologue by Akeno.

In the process of pulling out of Xenovia and cumming into Akeno's voluptuous cleavage, Koneko had been forcibly impeded from continuing her passionate rimjob.

"Koneko… You're very bratty and insistent for such a tiny girl. Your body didn't keep up with ours, did it…? All you got was that horrendous tongue, extended tail, and creepy erogenous senses."

"…You told me to not be ashamed of my tongue."

"Oh, my! I did! Don't be ashamed. In the end, the ruination of our bodies is just to please our beloved Black King! So, isn't it great that we grow to accommodate his masculinity? I sure love it …" Akeno mashed her tits up and down more. "…But you have been disrespectful to me. I'm Marcus' main girlfriend. He's in love with me. It's frustrating that you're constantly trying to impose. Don't you know to wait your turn…?" She approached Koneko, pressing the side of her boobs against her face as she brought an arm over her small shoulders.

"…" Koneko remained silent, maintaining eye contact with Akeno.

Was she scared of Akeno?

Her introspective nature did not make it readily clear.

…Akeno looked like a GIANT beside the tiny Koneko…

'It's not just her ridiculous boobs… Her height and hips and legs and ass and… And everything…! She looks even bigger than Xenovia, but without the muscles… And Koneko didn't change at all. The contrast is creepy…'

"Koneko…? Don't you have anything to say…?" Akeno pinched one of Koneko's cat ears.

In the process of doing so, she stopped squeezing her tits together, resulting in a steady drip of cum leaking from the bottom of her not-so-pressed cleavage.

Not a full stream or downpour; Merely a drip.

Her tits were so huge, firm, and round that they kept her cleavage tightly squeezed naturally, containing most of Marcus' load within her chest even without using her hands.

Right then, Rias discovered the answer to the question of Koneko's feelings.

The cat girl was not scared. Or, if she was, she was too obsessed with Marcus' cum to let it show.

As soon as the first drop of cum dripped from between Akeno's tits, Koneko subtly extended her extremely long tongue to catch it.

"…" All the while, she maintained eye contact with Akeno, pretending she was not doing anything.

Akeno's chest was so obscenely large that she could not see under her tits, thus missing Koneko's long tongue secretly scooping up semen mid-air underneath their shadow.

"… … …" The cat girl breathed heavily from feeling the texture of Marcus' creamy semen on her tongue. Unlike Xenovia, she did not seem to have an oral or throat obsession; The contact with her tongue was all she needed and wanted – though she was likely to enjoy drinking it if ever allowed to.

"Ah, Koneko… I get it. I've been hogging Marcus too much. Just like with Xenovia, I've neglected you, haven't I…?" Akeno made an ominous, eerie statement as she played with Koneko's cat ear.

If Koneko had been paying attention, she might have done something to prevent what was about to happen. Unfortunately for her, she was too distracted stealthily capturing the drip of semen coming from Akeno's tight cleavage valley.

By the time Koneko realized it, she was bent over nude against the wall with her small ass sticking out and Marcus' massive cum-wet cock prodding her minuscule butthole.

"M-M-Master, she won't be able to-"

"Oh, my! Are we machines on a loop? Must we do this again and again? Just do what I tell you. Did Rias not leave you in my care? Am I not keeping your horrid curse sated by letting my body become an abomination-"

"O-okay! Okay!" Marcus caved.

As big and strong as he was on the outside, he was just a tiny and weak boy on the inside, and Akeno had turned into an unhinged maniac.

There was no emotional power in his heart to stand up to her; Not without Rias' help.

'I'd help…! Marcus, I'd help…! She's hurting you! But…! But…!'

RUB…! RUB…! RUB…!

'These intrusive thoughts are so strong…! Oooh … And now my body is being controlled by involuntary actions too… The curse has overtaken me more than I realized until now…! As soon as I gain control again… I'll help…! I don't want to take advantage and masturbate to your suffering, Marcus…! I swear…! Just hang on for now…! While I… While I rub off as these women devour your cock and bully you !!!' Her slit twitched and heated as her fingers mauled it in circular motions, oozing juices.

RUB…! RUB…! RUB…!

PINCH…! KNEAD…!

Marcus tensed up, nervous to penetrate the petite Koneko.

"Do it." Koneko said, surprising him and impressing Akeno. "I can take it. I am strong."

"Oh, my… I like that attitude." Akeno grinned. "See, Marcus? It's not the dog in the fight that matters, but the fight in the dog… Or in this case, the cat. Xenovia is twice her size and was terrified, but Koneko knows best. She can take it. Especially with all that sperm lube on your cock."

Koneko nodded.

"…So I want you to grab her tail with one hand and her ears with the other while you fuck her ass."

"Heh?" Koneko's courage vanished.

"B-but-"

"…" A simple stare by Akeno silenced them both.

…

Nothing special happened.

No savior or grand trigger.

Marcus slowly suppressed his hesitation…

Koneko slowly clenched her teeth and tensed her small body…

Akeno slowly platformed her underboobs with her forearm to keep more cum from leaking…

And…

SCHLURGE!

… One-third of Marcus' cock was FEROCIOUSLY slammed into a butthole built to take none of it; Meanwhile, Marcus pulled both her cat ears with one hand and wrapped his tail with a cruel grip around his other hand.

Akeno's grin grew into one of sheer awe.

Koneko's tiny asscheeks split freakishly far apart to let Marcus insert a mere third into her anal hole. A gigantic, HORRIFYING protrusion popped up in her flat midsection, occupying half its width with its immense girth. Her feet tiptoed up to endure his penetration due to how roughly he pulled on her tail and ears, and how high his hips stood compared to her butt.

For better or worse, Koneko did not pass out.

"G-ghnn… U-ughh… O-ooh..." She grunted and groaned with a PAINFULLY strained voice, unable to make any real sounds due to the HARROWING pressure against her abdominal muscles. Both her eyes turned scaringly bloodshot, with one bulging wide and the other constricted and halfway shut. Her teeth clenched HARD, with veins popping all over her face.

"Deeper." Akeno ordered.

Marcus hesitated.

She touched Koneko's body with two fingers. "…Deeper."

A threat of electrocution.

There was no way around it other than standing up to Akeno.

…The timid Marcus lacked that bravery.

SCHLURGE!!!

"GHHHHHHHHHHHHHHHHHHH !!!" Koneko screeched and convulsed in place with more veins popping all over her body – especially her tense neck from lack of breathing and her stressed calves from the effort of standing on her tiptoes with such a heavy, turgid cock CRUSHING her guts.

Marcus had imposed another third into her miserable, suffering asshole. Her small asscheeks split apart to a point that Rias had not fathomed was even possible.

Unlike Xenovia, Koneko did not have enhanced abdominal muscles that could challenge Marcus' cock by contracting and pinning it in place. Therefore, she was the only one suffering; Marcus did not even grit his teeth, able to push further if needed.

'…Push further if needed…?' Rias examined Koneko's petite figure.

There was simply no way.

Not without destroying her insides; Rearranging and reshaping her rectum to replicate the exact shape of his cock, down to the veins and bumps.

"Deeper." Akeno commanded again.

Marcus already knew better than to bother hesitating.

He squeezed and pulled her ears and tail hard, forcing her back to arch painfully…

PLAP!!!!!

…And crashed his veiny crotch against her minuscule ass.

His full cock was inside her; His balls struck her wet slit in the process of slamming in.

"…!!!!!" Koneko made no sounds.

She had not passed out. Instead, it was merely impossible to communicate.

The cock bulge in her body went further than her midsection thanks to how indecently big Marcus' cock was, popping between her small, perky tits;

Her eyes rolled up, half-closed;

Her EXCESSIVELY LONG tongue dangled out, drooling;

Her ears and EXTREMELY LENGTHY tail thrashed and convulsed within Marcus' large hands;

Her face turned a DANGEROUS shade of red;

Her body was clad in veins from head to toe;

Quivering and trembling overwhelmed her small figure;

Tears poured down her cheeks;

Her tiptoed feet partially rotated inward.

'Huh…?' Rias paid extra attention to Koneko's tiptoed feet.

They had partially rotated inward.

She blinked multiple times to make sure she was not imagining it.

They had partially rotated inward.

It was not for better balance; It was simply impossible not to happen. Her asscheeks spread so far wide that her entire legs were forced to partially rotate inward, along with her tiptoed feet.

…A truly mismatched penetration between a huge Black King and a tiny Rook…

"Oh, my… Now that is a distension if I've ever seen one…" Akeno squatted to look at the monstrous cock bulge in Koneko's flat midsection. "She certainly isn't equipped to handle your powerful cock, huh…? The curse's modifications on her body were quite unfavorable. Oh, well! Make sure to really give it to her."

"What…? You want me to fuck her?!"

"…Yes. And I want you to have a load ready for me by the time I'm back." Akeno put her tank top back on, letting the semen drip coming from between her tits smear it from inside.

"When you're back?! Where are you going?!"

"Marcus."

"H-hm…?"

"You've got a cock that needs to be pleased to protect others. Shouldn't you be thrusting it? Honor Koneko's noble anal sacrifice. Oh, and… Don't cum inside her. It's MY load."

Marcus was too cowardly to say anything.

"Oh, my! Don't pace yourself. I'll be back soon to take your juicy nut into my lovely Queen tits. As a reward, I'll give you lots of cowgirl service tonight."

Akeno portaled away.

Without her there, Marcus had no need to obey-

PLAP! PLAP! PLAP! PLAP! PLAP!

He obeyed, pistoning his hips back and forth with immense power.

Too much power.

…Marcus was way, way too big for the petite, tiny Koneko.

"… U-ugh … … O-ooh … … Mngh …" The weak, suppressed, strained groans that came out of her oxygen-deprived throat were WILDLY disconnected from the FURY with which her minuscule asshole was being hollowed out.

What a difference it made to be meaty and curvy when bred by a muscular, tall, hung Black male.

Rias mentally compared Koneko's experience with her own.

When Rias got vaginally pounded by a passionate, vigorous Marcus, her ass turned red from how his hips aggressively and repeatedly collided against her round, fleshy rear.

When Koneko got anally pounded from behind… There was no such flattening, even though their hips collided thanks to merciless balls-deep lunges.

Koneko was simply too slim for that.

It was a brutal sexual slaughter involving two utterly incompatible bodies.

Every slam ended with her upper body being so thrown forward that her small tits and bulged-out torso squashed against the wall while her back arched so much that it looked like her spine would break.

Then, he pulled back with enough force that her body returned to its original bent-over tiptoed stance because of how tightly her body clamped around his humongous black cock.

Through each cruel thrust, his hands tightly held her cat ears and tail, ensuring she had no choice but to get skewered in place.

PLAP! PLAP! PLAP! PLAP! PLAP!

"… H-hooh … … K-khhn … … U-ungh …" It took literal seconds for her arms and legs to go fully limp. No longer did her hands support her against the wall or her feet balance in place by tiptoeing.

It was all Marcus, relentlessly holding onto her ears and tail.

'Sh-she's gone…! She's gone…! He's killing her with his big black cock…! She can't breathe…! Look at her face…! It's like with Xenovia, but ten times worse…! He's too big for her…! She's choking on nothing but her guts being pushed around inside her tiny body…! His cock is shredding through her…!'

The fact the sexual destruction was entirely silent if not for sheepish groans and LOUD wet clapping made it look even more brutal and dominant.

'Wet clapping…? Wait… Why is it so wet…?' Rias only took note of the wet collisions now, too distracted by the visual of Koneko's small body being sexually decimated.

Her eyes moved to Koneko's pussy.

It squirted a thick, warm load of pussy juice every single time Marcus slammed into her miserable asshole.

PLAP! PLAP! PLAP! PLAP! PLAP!

GUSH! GUSH! GUSH! GUSH! GUSH!

'Woah …' Rias was in awe of the consistency. No thrust went unrewarded.

Was it because her sensitive pussy delighted in the feeling of Marcus' heavy balls punching it with pendulum swings every time he pistoned?

Could it be that there was great anal pleasure even amidst penetration that compromised the integrity of her insides?

Perhaps her guts were so crushed and rearranged that her womb and pussy walls were stimulated in the process, smashed due to a sheer lack of room inside her petite body?

Whichever the answer was, there was no doubt that Koneko was bathing in EXTREME pleasure, gushing squirt after squirt after squirt after squirt…

'I wanna cum that much too… ! I wanna, I wanna, I wanna… ! A-aaaah… !'

RUB…! RUB…! RUB…!

PINCH…! KNEAD…!

Rias worshipped Marcus' sexual prowess and masculine, hung body.

Nevertheless, there was something she worshipped even more.

His dominance.

It was a rare thing to see because he was so timid and passive… But she knew how powerful it was when it took over him.

'When he stopped holding back after I encouraged him enough in the gym equipment room, he took charge and used me like a sexhole… And he's doing it now… !' Her eyes adored what Marcus did next.

He raised Koneko in the air by the cat ears and tail, removing all contact between her feet and the floor.

PLAP! PLAP! PLAP! PLAP! PLAP!

"…" Koneko lost all groaning capability, mentally and physically shattered from swinging back and forth as Marcus held her bent-over in the air by nothing but the cat ears and tail. Her excessively long tongue dangled mindlessly, drooling foolishly.

Rias had not noticed it until now, but Marcus did not look his usual self.

Gritted teeth; Frowning expression; Forehead vein; Unrestrained pistoning.

'He's angry… That's so rare… I… I love iiiiiiit !!!'

RUB! RUB! RUB! RUB! RUB!

PINCH! KNEAD! PINCH! KNEAD!

"Get angry at *me*... ! Fuck *me*… ! Fuck *me* bent-over mid-air like that… !" Rias whispered to herself with a hanging tongue, wide eyes, and a wide open-mouth smile.

RUB! RUB! RUB! RUB! RUB!

PINCH! KNEAD! PINCH! KNEAD!

"Breed me... ! I'll treat you better than Akeno… ! I'm not selfish like her… ! I care about your feelings… !"

RUB! RUB! RUB! RUB! RUB!

PINCH! KNEAD! PINCH! KNEAD!

"Issei can't fuck me like that… ! I'll be your queen… ! Be my Black King… !

"Oh, my! But *I* am the Queen."

"HUH?!" Rias flinched from surprise, pulling her hand back from her skirt as she turned around.

That motion might have been a mistake. By the time she fully turned around, her face was buried between a pair of GIGANTIC, SWEATY, CUM-DRENCHED tits, pinning her head to the wall as her ass involuntarily sat on the toilet.

Not only that, but…

PLAP!

"MNGH !" …A HARD, LARGE cylindrical object reached DEEP into her pussy, hitting the back of her womb with crude technique. "Hmngh?!" She could not speak or see due to the immense valley of cleavage turning her world dark and keeping her pressed to the wall.

"Oh, my! It was so easy to put in. Marcus must have gaped it for life during your short relationship." Akeno giggled.

Rias did not understand what was happening. It was too sudden, too quickly.

Still, she did quickly grasp one important fact.

PLAP! PLAP! PLAP! PLAP!

"Ghnm ! Mngh ! Unghm ! Nghm !" There was a massive cock slamming back and forth into her tight, soaked pussy. 'A strap-on?! It has to be! Akeno is fucking me with a strap-on?! She knew I was here the whole time?!'

Akeno FLATTENED her breasts HARD against Rias' face to ensure she was fully pinned in place. At the same time, she folded Rias' lower body up by locking her arms under her kneepits.

A perfect position for aggressive, crude pounding to take place.

PLAP! PLAP! PLAP! PLAP!

"Mngh ! Unghm ! Ghnm ! Khnm !" …Aggressive, crude pounding took place.

Akeno slammed her hips forward with decisive force, making Rias shake and ripple from the impacts and pleasure of having an enormous cylindrical object gouge deep into her pussyhole.

It did not feel as good as Marcus' cock; It was not as big as Marcus' cock; It was not hot like Marcus' cock.

…But it was more than powerful and unrelenting enough for someone whose pussy yearned for harsh penetration…

'I'm gonna cuuuum… ! I can't breeeeathe... ! Let me move my heeeead… !' Rias had trouble resisting and flailing her arms due to the colossal valley of cleavage smothering her sight into darkness. 'Huh…? Wait… Isn't it a little greasy and sticky here…?'

Her memory flashed to moments ago.

The cumshot Akeno stole from Xenovia's asshole.

It was rubbing against her face…!

"Shlrrrrrrrrrp ! Shluuuuuuuuurp !" Rias quickly lost all interest in resisting, letting her arms rest by her sides as she licked up every drop of Marcus' rich cum from inside Akeno's cleavage.

It was the curse's fault.

If not for it, she would free herself and not submit to such an abrupt, vile assault.

…Instead, she lost control to the intrusive thoughts and desires…

PLAP! PLAP! PLAP! PLAP!

"Shluuuuuuuuuuuuuuuurp ! Ghnmmm !

"Oh, my! It's so tight and wet inside you, Rias! Or so I think… It's not like I'm feeling a thing."

PLAP! PLAP! PLAP! PLAP!

"Shlrrrrrrrrrrrrrrrrrrrp ! Mnghhh !"

"That's okay! I'm not looking to milk myself inside your pussy. I just want to play with you a little bit… I couldn't contain myself. I knew you were in here. The windows are tinted, but you made it wet with your fingers, so I knew some slutty bitch was rubbing off in here."

PLAP! PLAP! PLAP! PLAP!

"Shloooooooooooooooooorp ! Uuuungh !"

"I knew it'd be you! You're an envious little whore, aren't you, Rias? I could tell from the way you've been glancing at Marcus since we swapped…! Do you miss him?! Do you regret swapping?! Are you not happy with Issei's limp Asian worm?! Do you need a big black cock to feel like a woman again?!"

PLAP! PLAP! PLAP! PLAP!

"Shlrrrrrrrrrrrrrrrrrrrrrrrp ! Nghhhhh !"

"Well, GET OVER IT! He's all mine! I'm his number one, can't you tell?! He loves ME the most of all! I please his cock like no one else! Look what I let happen to my tits for him! This is true love and he knows it! He recognizes it! That's why he devotes his cock and body to ME! His cum is all MINE! All you get is Issei's little shrimp! You wanted him, SO BE HAPPY WITH HIM!"

PLAP! PLAP! PLAP! PLAP!

"Shlrrrrrrrrrrrrp… ! Mnghhh… !" Rias felt her consciousness waver as lack of air gradually overwhelmed her brain; The more cum she licked and the more Akeno pistoned, the more the massive breasts squeezed and molded around her head, giving her no room to breathe.

"You can watch and rub off like a voyeur creep if you want, but he's all MINE! If you try to get in the way of our relationship, I won't just tell Issei that you're a liar! I'll unleash him on every girl in this school! You're going to see a pandemic of girls corrupted by the Black King curse! Pregnancies everywhere! Tons of mixed little kids! If you want to avoid that, LEARN YOUR PLACE!"

PLAP! PLAP! PLAP! PLAP!

"Shluuuuuuurp … Nghhhhmmm …"

"Oh, my! Am I smothering you TOO much? It's difficult when these are so big. Forgive the accident, Rias." Akeno pulled her upper body back just enough to give Rias enough room to breathe.

Their eyes made contact.

…There was no genuine apology on the nude Akeno's face, grinning as sadistically and maliciously as she could.

"A-Akeno-"

"Oops! You got enough air already?!"

SMASH!

Akeno pressed her spit-and-cum-soaked tits against Rias' face again.

"Shlrrrrrrrrrp !" Rias once more lost herself to the trance of licking up delicious cum.

PLAP! PLAP! PLAP! PLAP!

…And Akeno resumed pounding at full force.

"If you need someone strong to dominate you because Issei is not good enough, Rias, I'll do it. Is that good enough for you?! My cock might be fake, but it's as close to a big black cock as you'll ever have again! Because Marcus is MINE!"

ZAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP!!!

"MNGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHM !!!" Rias' legs shot straight and wide, spreading so far to the sides that they formed a perfect split while quivering and trembling maniacally in the air.

Not only was Akeno smothering her with her huge tits, AND berating her, AND cruelly slamming into her neglected pussy, but ALSO sending powerful electricity through her body, thus making her inside CLENCH around the fake penis with IMMENSE force.

It made her lose track of reality; Of time.

"GHNMMMMMMMMMMMMMMMMMMMMMMMMMMM !!!" The only thing she had any sense of was the GIRTHY object punching the back of her clenched-down uterus and the STRONG, WET heat between her legs.

She squirted nonstop all over Akeno.

Rias was not the only one suffering.

PLAP! PLAP! PLAP! PLAP! PLAP!

"…" Koneko continued to be silently and brutally pummeled outside.

How much time passed?

Was it only a couple of minutes? Or over an hour?

It truly was impossible for Rias to track anything when she was stuck in endless loops of breathless squirting and electrocuting.

"Hah … Hah … Hah …" Eventually, Akeno pulled her breasts back enough, letting Rias' teary-eyed face hang to the side as she recovered her breath with her tongue out of her cum-dripping mouth. "Hah … Hah … Hah …"

"Hah… Hah… Hah…" Akeno, too, breathed heavily from the strenuous hammering. "Oh, my… Did I push you too far? Since you were so eager to get dicked black by my boyfriend, I thought you could handle a fake black cock… Was I wrong…? Was it too much, Rias…? I guess you don't have the body to handle Marcus if you can't even handle this."

"Hah … Hah … Hah …" Rias offered no rebuttal, still coping with lingering orgasms and breathlessness.

"That's right… You DON'T have the body to handle Marcus. Look at these tits of yours… So small." Akeno touched Rias' nipples with her index fingers.

"W-wait… Wait…"

"How can you expect to please such a big and masculine hunk when you don't have GROSS, FAT, ANNOYING TITS?!"

ZAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP!!!

"MNGHOOOOOOOOOOOOOOOOOOOOOOOOOH !!!"

"What's the point of screaming like this?! I already applied a soundproof spell in this stall, you envious bitch! Are you trying to summon Marcus here so he fucks you?! ARE YOU THAT DESPERATE OF A CHEATER?!"

ZAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP!!!

"UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUNGH !!!"

"Huh?! HUH?! Why are you squirting so much?! Why are you shaking so much?! Could it be that you can cum from your nipples being abused this little?! You have sensitive tits even when THEY'RE SO SMALL?! IF YOU'RE GOING TO HAVE SENSITIVE TITS, MAKE SURE THEY'RE BIG AND CUMBERSOME FIRST, YOU SLUT! COMMIT!"

ZAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP!!!

"MNGHUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUH !!!!!"

"There we go, there we go… I was too mean to you, too mean to you… Relax, relax…" Akeno gave Rias a break… But never stopped grinning, scowling, or pressing her index fingers against her nipples; Nor did she pull out of Rias, keeping the huge strap-on intimately connected to the back of her stretched-out womb.

Psychotically insatiable; There was no better term to describe Akeno's corrupted mind. No amount of abuse or sadism could appease her negative feelings, which she infinitely vented on others.

"I hope we understood each other. Don't get in the way of my loving relationship with Marcus. If you want to watch like a sad little cuckquean, enjoy yourself… Otherwise, worry about the fake cure you owe everyone instead of the black cock you miss so much. It's mine now. I won't ever let you get close to it again. It's not like Marcus would want you anyway… He loves me, who offers him multiple pussies to breed. I'm a devoted girlfriend, not a hesitant nun like you, who made him feel so guilty for his urges."

"Hah … Hah … Akeno…"

"Hm…?"

"Y-you need to stop…"

"Stop…?"

"Can't you tell that you've lost it…? The curse… Has completely warped you… Hah … hah …"

"…You think I'm not aware that the curse affected me?" She asked, insulted.

Akeno was referring to the obscene, sweaty, greasy tits that consumed so much space between them.

"I-I don't mean physically! I mean-"

ZAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP!!!

"NGHHHHHUUUUUUUUUUUUUH !!!" Even without any thrusting, the fake cock buried into her soaked pussy brought great stimulation as her walls and uterus clamped down from the spasms caused by electricity.

"Oh, my! That was just my way of saying I'm very much aware that Marcus' semen has affected me. I hope you understand when I reward such a STUPID QUESTION with a little bit of mean-spiritedness."

"Hah … Hah … I mean mentally, Akeno…! Mentally…! I get it…! I'm being affected too…!"

"Affected? You…?" Akeno kneaded and squeezed Rias' large tits, showing no regard for hurting her. "With these small tits?"

"I told you…! Hah… ! I'm talking mentally…! My mind is getting invaded by intrusive thoughts…! Sometimes, all I can think of is Marcus' big black cock… The idea of being knocked up… Cheating on Issei… Chugging rich cum … I have to fight so hard to control myself!"

"Hoh… Aren't you meant to be resistant to it? I thought you hadn't been affected in the slightest." Akeno stopped grinning, intrigued by Rias' words.

"I AM more resistant because I'm a High-Class Devil, but I'm still affected a little bit! You're still in there, aren't you?! You can fight it! You can take control-"

"Are you telling me that I can ruin you for Issei if I feed you enough cum then?" Akeno asked with the coldest voice, gaze, and expression possible.

'Oh, no.'

Rias had made another mistake.

Akeno would now do everything in her power to corrupt Rias.

…

HAD she made a 'mistake'?

…Or was it an intentional moment of self-sabotage by intrusive thoughts she did not even notice were there…?

'If I am tainted by enough Black King cum, I'll end up as a nympho bimbo who lives to be bred by Marcus' big black cock … I'll submit without caring anymore…!' The prospect was unacceptably exciting for Rias.

…

'I can't do thaaaaat!' …But also bad.

She had to fight the intrusive thoughts in her mind.

To do that, she had to fight the Akeno intruding her pussy.

Adrenaline rushed throughout her body!

"You're out of your mind if you think I'll let you do anything to me… Or to anyone else! You've lost it, Akeno!"

"Oh, my… Isn't that a little bold for someone who will cum the moment I move my hips the tiniest bit…? Maybe I should give you some more of the nipple shocking you love so much-"

Rias grabbed Akeno's wrists and frowned at her. "Try it."

The lack of change in Akeno's expression was concerning, not taking Rias' defiance seriously.

Why should she?

…The outcome of that conversation was highly predictable, and Rias knew it.

"…If you don't do what I say, I'll tell Issei the truth."

Losing Issei was necessary to stand up to Akeno and salvage her peerage.

…

Rias built up the needed courage. "I don't care-"

"…I'll unleash Marcus on this school and city. I'll have him knock up every girl possible."

Rias was caught off-guard by Akeno's escalation. "He won't obey you if I get in the way!"

"…Then, I'll expose his existence to the Devil Underworld."

"A-ah…"

"What do you think they might do if they find out there is a Black King piece in someone's peerage…?"

Rias had no idea, and neither did Akeno. It was a threat founded on chaos and uncertainty. Maybe nothing would happen, or maybe something terrible would happen.

Moreover, Rias was not even sure if she could keep Marcus from submitting to Akeno.

Not only had she grown terrifying and unhinged, but Marcus himself was timid and submissive by nature.

'…If only he manned up…! Khh…'

"Hey, Rias… Don't be so upset…" Akeno leaned forward, bringing her face right up to Rias'; Their breasts smashed together, with Akeno's VASTLY overshadowing and overwhelming Rias'. "…We used to be close. Let's be close again, okay…? As cum-drunk bimbos for Marcus… With me as his number one and you as his number two!" Her cold expression twisted itself into a psychotic, creepy grin, accompanied by unstable giggling.

Trying to argue with Akeno had been another mistake.

Rias was accumulating a lot of those.

'…It's the intrusive thoughts influencing my decisions…! They're getting me to make mistake after mistake…! I shouldn't have said anything…! Ah… A-ah… What do I do now…?!'

The answer was obvious.

'…Obey Akeno and become a little cock whore …' Rias mentally submitted.

"I think we have an agreement, don't we…? Wonderful!" Akeno pulled back. "Here's what we'll do-"

A sound coming from outside interrupted them.

PLAPLAPLAPLAPLAPLAPLAPLAPLAPLAPLAPLAPLAPLAPLAPLAPLAPLAP!!!

Marcus' fierce pummeling of Koneko's petite body and tiny asshole had significantly ramped up.

"Oh, my! He's about to shoot. We wouldn't want THAT happening, would we? Please wait here for a moment."

SPLOP!

"GHNN !" Rias shuddered from having her tight pussy roughly scraped out in the process of pullout. 'Hah … I'm so pitiful…' Her mind was filled with shame from noticing the BATH of pussy juices coating Akeno's large black strap-on.

"Do wait like a good girl." Akeno removed her strap-on, dressed up, and rushed out; Her meaty buttcheeks and oversized tits swung and flapped with each step.

"Ughh … Ungh …" Now that Akeno was no longer there, the adrenaline left her body, leading her body to sulk, exhausted and sweaty.

Because of that, she did not pay too much attention to what happened outside.

…Though, she could guess based on Koneko's PAINFUL screech, Marcus' VIRILE grunt, and the sounds of STICKY squelching…

There was silence for a bit.

Rias found the strength to turn her head and glance through the window.

Koneko and Xenovia were both on the ground, covered in sweat with their anuses prolapsed out… And Marcus was sitting on his ass, crying from Akeno's emotional abuse.

'He… Really doesn't have a heart that matches his body, does he…?'

"Don't pity him too much." Akeno said behind her, already naked.

"Khh…!" Rias was caught off-guard again due to overall dizziness.

"With me as his number one girlfriend, Marus gets to shoot dozens of fat loads a day. Meanwhile, Issei gets one out if he's lucky, and with very boring sex with a very boring redhead. If anyone is suffering, it's Issei, not Marcus. He's getting all the tight wet holes and breeding sex he needs . One of these days he's going to end up knocking me up. I can't wait for it … I hope he's excited to be a daddy. And if it's a girl… I hope he's excited to fuck her when she's of age… ! I hope I can adapt to anal sex quickly. I don't think pussy sex when pregnant is the best idea when his cock is that manly …"

Rias wanted to tell Akeno she had COMPLETELY lost it… But was not brave enough to stand up to her either.

There was no point anyway.

Antagonizing her would merely make what was to come even worse.

…And Rias knew what was to come.

Cum.

She could tell by looking at Akeno's arms under her breasts, keeping cum from leaking out of her cleavage from below.

"I had him shoot it all in my tits for you, Rias. In honor of our friendship and former throuple, please chug down eeeevery drop, okaaaaay… ?" Akeno rested her underboobs on Rias' face.

There was no choice but to drink.

"Ghlughlughlughlughlughlughlughlughlughlugh… !" …Not that Rias would have chosen differently.

…Her pussy lips quivered from ingesting the delicious, creamy substance…

"Chug it all down…! Let's modernize the heir apparent to the Gremory Clan by making her a blacked bitch…!"

"Ghlughlughlughlughlughlughlughlughlughlugh… !"

"I feel so bad for Issei… Poor him… While he's holding out for a cure, his girlfriend is chugging down Black King nut… !"

"Ghlughlughlughlughlughlughlughlughlughlugh… !"

"And he's only got the one too. His other girlfriend already became a Black King bitch ! Hahahahahahah !"

"Ghlughlughlughlughlughlughlughlughlughlugh… !"

"Maybe I'm a Black Queen! Do you like the sound of that?! Oh, that's right… You were fantasizing about something similar earlier, weren't you?!"

"Ghlughlughlughlughlughlughlughlughlughlugh… !"

"You can't be Marcus' Black Queen! That's ME! But you can be his second bitch, if you want. You let me be number two for so long, so I'll be just as generous back to you!"

"Ghlughlughlughlughlughlughlughlughlughlugh… ! Hah… ! Hah… ! Hah… !" Rias was allowed to breathe after finishing up Marcus' extensive load – and the sweat puddled up between Akeno's huge tits. "A-Akeno… Akeno, you're wrong…!"

"Hm…?"

"You're not Issei's number two! He loves us both equally! He misses you!" Rias could not help but try to reach her friend one more time.

It was pointless.

"Really…? That's too bad, because I'm never going back to that tiny Asian dick !" Akeno giggled. "And neither will you after I'm done with you."

"A-a-a-ah…" Rias had no recourse left.

Akeno brought a hand in front of Rias' face…

SNAP!

…And snapped her fingers.

"From now on, whenever I do that, you'll take Marcus' cum one way or another. Immediately. Wherever you are. No matter if Issei is there. Either in your holes or on your skin. And no one can know, okay…? Including Marcus."

"H-heh…?"

"Unless you want to see what happens if you disobey me. Don't worry… I'll help you not get caught, okay…? You can trust me… After all, you trusted me with keeping Marcus' big black cock sated and I'm doing a great job at that, aren't I?! I keep my word!"

Did Akeno provoke Rias on purpose, or did she truly believe her words?

'I have no idea…! Her face…! She's absolutely crazy now…!'

"Ah, Rias… When you look at me that way, I can't help myself. Let's go for another round, okay? Let me enjoy the experience of blacking a bitch."

"H-hm…?"

PLAP!

"MNGH !"

ZAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP!!!

"GHNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN !!!"

Akeno used Rias' pussy, electrocuted her nipples, and tit-smothered her face for a long, long while more.

Things spiraled more and more out of control.

What should Rias do?

'That's right… I had to do something after the volleyball game ended but I came here instead… That might help… What was it again…?'

She could not remember.

"MNGHUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUH !!!"

Marcus cried to himself, sitting against the wall outside the bathroom building.

A minute ago, Master returned to portal herself, Ms. Xenovia, and Ms. Koneko back home. Even though there were still classes that day, their bodies were in no state to continue.

Before portaling away, Master did one weird thing that Marcus did not understand.

SNAP!

She stared at the bathroom building and snapped her fingers.

'I don't know why she did that, but I also don't know why she does anything. Master is an evil woman…' Marcus continued to cry to himself, hugging his legs. 'Ah… I should… Dress up…'

Before he could grab his clothes from the floor…

"Marcus. Are you okay?" …Ms. Gremory turned around the corner, getting on her knees beside him to level her gaze with his.

"A-ah… Master- I mean, Ms. Gremory…" Marcus no longer referred to Ms. Gremory as 'Master'.

…If Master found out he called anyone else Master, she would berate him like never before…

'I'm so scared of her… But I can't show it to Ms. Gremory…'

"Akeno is pushing you too much, isn't she?" Ms. Gremory surprised Marcus with a direct callout of the truth.

"U-uhm… Master is a little demanding… But it's okay. Please don't worry. You and Issei deserve to be happy together without me causing problems… I can handle my needs with Master."

"Marcus, it's okay." She grabbed his shoulder. "…I know the truth. Akeno has… Changed a little, hasn't she?"

Marcus hesitated to answer. "…A little."

"A lot."

"…A lot." More tears flowed down his eyes.

It was his fault. Because of his cursed body and semen, the kind Ms. Akeno Himejima turned into the dreadful Master; A succubus obsessed with emotional and sexual abuse. Marcus had no idea what went on in her head.

…Sometimes he felt so angry that he wanted to rape her until she begged for relief…

'That's evil… I'm evil… My body is evil… This huge penis is evil… I should have died instead of becoming a Devil…'

…

But he did not die.

Because of Ms. Gremory.

It was a little bit her fault too.

…And she abandoned him with Master…

…So it was even more than a 'little bit'…

…Marcus felt angry-

"It's okay." A soft pillow pressed against one side of his head; A pair of thin, feminine arms wrapped around the other side.

Ms. Gremory hugged his head to comfort him.

…

Marcus cried more.

How could he blame her for saving his life?

If anything, it was on him to have better control of his body and urges.

"Marcus… Let me help you…"

"Help me…?"

"Mm-hmm…"

STROKE…

"Huh…?" Marcus was surprised by the feeling of a soft, small hand gently stroking his permanently-erect cum-soaked cock. "Ms. Gremory…? I don't need to cum right now. Master makes sure… Uhm… That my pipes are always clean and healthy…"

"It's not for the Black King curse. You're not just a Black King or piece. You're a person, aren't you? And you're hurt… So you deserve comfort. Leave it to your old Master…"

STROKE… STROKE… STROKE…

"B-but… Uh…"

"You love me, don't you? I know that you do. So, won't it feel good to be consoled by me? Let me give you this much relief, at least…"

STROKE… STROKE… STROKE…

"What about… Issei…?"

"He doesn't need to know. It'll be our secret. Just relax and let the old Master you love take care of your big black cock… I'll enjoy it too… It's a very healthy cock."

STROKE… STROKE… STROKE…

"Ms. Gremory…! Are you switching places with Master again?! I don't think Master is going to be very happy-"

"No."

"No…?"

"No. I told you. It'll be our little secret… Because your cock deserves love too, not just rough milking. Don't tell anyone."

"Th-then… Ah… I see…"

Something was off about Ms. Gremory, and it was not just the thin layer of sweat on her body, or the odd smell coming from her stained clothes.

…She did not sound genuine…

"It's okay… I know your cock needs a whole lot more than just hand stuff to be pleased. Let me properly comfort you, Marcus… The way I should have when I was your Master." She removed her panties, half-squatted over his lap, and aligned the tip of his tall cock with her pussy under her skirt.

It was soaked… And slightly gaped and swollen for some reason.

'Ah… Ms. Gremory's pussy… Feels so good…'

"I will ride you the best I can, alright? Feel free to release all your cum inside me as many times as you want."

"But… The curse…" Marcus worried about Ms. Gremory turning into a monster like Master.

"Don't worry. I'm resistant to it, remember? You don't have to worry about me changing in any way. It doesn't affect me."

"You didn't feel anything odd since you switched places with Master?"

"Nope. Not a thing." She smiled with a light head tilt.

…Ms. Gremory did not sound genuine…

"Uhm… Can't you do something about her…?" Marcus asked with great guilt. 'I shouldn't be demanding anything… It's all my fault…'

"About Akeno?"

"Yes…"

"This is the best I can do, I'm afraid."

"I see… There really is no cure, is there…? You're just saying that to keep everyone calm…" Marcus looked down as more tears rolled down his face.

"A-actually, there might be!"

"Heh?"

"Y-yes… I've been talking to Sona and she might be onto a breakthrough any time now! I-isn't that great?! All the more reason for you to take it easy and let me comfort you!"

…Ms. Gremory did not sound genuine…

"That is great…!" …But Marcus believed it anyway.

Ms. Gremory would never lie or deceive him.

She was the one woman who cared for him.

If he trusted anyone, it was her.

…

'She did lie to me one time…'

In the gym equipment room, when they first had penetrative sex.

Back then, she pretended to be falling in love with him so that he felt less guilty about using her body and ruining her relationship with Issei.

He did not realize it at the time, but later when she accepted switching places with Master.

'It hurt a lot, but it was to protect me. It's my fault for hesitating so much to have sex with her. I'm such a burden…'

"Marcus."

"Yes…?"

"I'm going to ride you now. Release a ton of cum, okay?"

"Ah… Yes, Ms. Gremory."

She bit her lips and readied herself to move her hips down.

'Ms. Gremory is such a good woman… She knows how much I love her, so she's going to comfort me with her body… Ah… I'm so selfish-'

PLAP!

Ms. Gremory crashed her hips down and threw her head back; Her tongue shot out of her mouth as her eyes rolled up. "Ooooooooooooooooooooooooooooooooooh !!!"

"M-Master-"

PLAP! PLAP! PLAP! PLAP!

"Nhgoh ! Oooh ! Ungh ! Mngh !" To Marcus' surprise, Ms. Gremory PROMPTLY began squatting up and down at a vigorous place, explosively flattening her round ass and bulging her lean stomach under her corset with his massive cock. The back of her womb felt warm and tight, with every inch of her insides clamping down against his veiny cock.

Her body was not as 'developed' as Master's. Because of that, it was shocking to see her so skillfully and smoothly squat up and down, swallowing his full length from tip to base each time.

'No… Wait…' Marcus paid more attention, not letting himself get distracted by the gorgeous sight and erotic wails coming from Ms. Gremory.

There was nothing skillful about her squatting. Comparatively speaking, Master rode much better due to having more experience from night after night of using him.

Ms. Gremory was riding so thoroughly and energetically based on passion alone; Her technique was quite sloppy.

Not only that…

PLAP! PLAP! PLAP! PLAP!

"Mngh ! Uuungh ! Hooh ! Mnghoh !" …But she quit making eye contact with him the moment she began riding, losing herself to a wide smile, dangling tongue, tears, and rolled-up eyes.

It was like Marcus was not there.

How odd.

…Why was it suddenly so hard to tell the difference between Ms. Gremory and Master…?

"MNGHUUUUUUUUUUUUH !!!" She wailed as her pussy bathed his greasy eight-pack abs with hot squirt.

Ms. Gremory sounded genuine.

Something was wrong.

Asia was certain of it!

'Akeno told everyone that Rias is finding a cure for Marcus' curse… But it doesn't feel like it! And it doesn't feel like Akeno is taking good care of him either! Am I crazy? I feel like I'm the only one paying attention…!'

Moved that thought, Asia went to the courtyard bathroom building to investigate, hoping to find something to prove her suspicions.

Curiously enough, she did not find Akeno, Xenovia, or Koneko in the building.

Instead, she found…

'…A-a-a-a-a-a fake penis?!' It was inside one of the stalls, soaked in smelly, sticky fluids amidst a puddle of more smelly, sticky fluids. 'Th-this thing looks like it's supposed to be latched around someone's hips… And it's so big…! I-I-I don't understand, but this is weird, isn't it?! Maybe if I take this with me and show it to someone, they'll listen to me!'

Asia reached down to grab it-

'Wait!' She stopped herself halfway through.

Asia had almost made a crucial mistake.

There were traces of semen on the fake black penis.

If she had touched it, who knows what might have happened?

'I don't understand much, but I can tell that it only takes a little bit of contact one time for things to start getting weird! Like it happened to Koneko and Xenovia…! But I still want to use this as evidence… What should I do…? Ah, I know!'

Asia ran back to the classroom, grabbed her backpack, and ran back.

If she carefully put it in her backpack without touching it directly, she would be fine!

…But the fake penis was no longer there.

'Heh?! Who took it?! Ah… What do I do-'

PLAP! PLAP! PLAP!

"Nghoh ! Mnghoh ! Oooh !" A woman moaned gutturally somewhere behind the courtyard bathroom building.

Asia had not heard her the first time because she was so shocked by the fake penis.

'A-a-ah…' She almost approached the window to see what was happening.

…But ultimately ran away without looking.

Asia was too scared of harsh, vulgar things.
