Boku no Hero Academia: Izuku's Harem Academia

Disclaimer: This is amature-rated fanfiction story of Boku no Hero Academiathat I am writing for erotic fun. Needless to say, this story is AU, the characters may seem OOC to some and there will be smutty lemons. Also, I own nothing of the series other than the fanfiction stories that I make.

Chapter 3: Sumomo and Tooru

Izuku woke up from his slumber and was glad that he had Sumomo with him to keep him company as he hated the idea of waking up alone after spending two nights with Ochako and Tsuyu. He smiled affectionately at the cute ball of slime and stroked it gently, causing it to quiver in response. Sumomo soon woke up and looked up at him with a sleepy look on its "face". The slime girl then woke up fully and had a mischievous look in its eyes before it suddenly rushed into his pants.

Barely keeping himself from crying out in panic, Izuku whispered, "W-what are you doing, Sumomo-chan?"

Izuku got his answer soon enough as something warm and slimy suddenly engulfed his morning wood and even started to ooze through his urethra to reach his bladder and prostate. He quickly covered his own mouth with his hands to stop himself from gasping in pleasure while his whole body shivered and shook due to Sumomo's apparent attempt to give him her own version of fellatio. He could feel Sumomo's slimy appendage moving in and out of his urethra while the rest of her slime-like body stroked and massaged the glans of his phallus.

Normally, insertion of a foreign object into the urethra has to be done carefully to prevent urinal incontinence, damaging the urethra and infections. However, since Sumomo's soft and slimy appendage could change shape to perfectly fit into Izuku's urethra without causing harm to it, Izuku felt little to no discomfort as he felt new sensations which he did not even realise were possible.

"N-not even Tsuyu-chan can do something crazy like this!" thought Izuku.

As for Sumomo, due to being comfortable with being her true slime girl self with not only Izuku but also Ochako and Tsuyu, she was perfectly happy to make use of her increased physical and mental freedom to pleasure all three of them in her own way. Indeed, just as Sumomo was pleasuring Izuku's member with her slime-like body, her physical copies did their own versions of cunnilingus on both Ochako and Tsuyu. Both girls were rendered helpless as their respective physical copies of Sumomo started to insert themselves into their increasingly moist nether parts to the point of oozing into their very wombs. Ochako and Tsuyu's sexual pleasure only grew as Sumomo started to stroke and massage their erect clitorises and even insert narrow slimy probes into their urethras to stimulate them. Before long, Izuku started to stroke his own penis while Ochako and Tsuyu fingered their own private parts to bring themselves to orgasm.

It should be noted that, due to past trauma involving a former host who had a fetish for excrement, Sumomo stayed clear of their anuses.

Due to the intense sensations on not only his phallus but also the urethra of the said phallus, Izuku quickly climaxed which caused Sumomo's body to swell with his white seed. While Izuku breathed heavily to recover from the intense orgasm, Sumomo slowly oozed out of his still-erect member and reformed into it's previous state as a cute-looking ball of slime. Speaking of climaxes, Ochako and Tsuyu also climaxed and each copy of Sumomo fed on their expelled vaginal fluids.

After Izuku caught his breath, he noticed something off about Sumomo and asked, "Sumomo-chan, is it just me or are you changing?" Although Sumomo still appeared as a cute-looking ball of slime, it was apparent that she not only had "eyelashes" just like the previous night but even had round bright-pink blushes on her "cheeks" and a small fold which formed a cat-like "mouth".

Sumomo nodded and placed an elongated slimy appendage into Izuku's ear to fully explain to him through her link with her host, "I think I am. This has never happened before."

Being a keen analyst on quirks even before he became a student of U.A. High School, Izuku asked her, "Do you think it's because you no longer need to keep constant control over us like with your previous hosts?"

"That… might actually be the case," said Sumomo who then added, "I never felt truly relaxed or safe until I met the three of you after all."

"Given the fact that you didn't develop while you were in your previous hosts due to your constant need to be in control, it's probably safe to assume that your lack of development is either due to a mental block caused by stress or due to energy expenditure to keep your previous hosts constantly under control. Now that you're with us and you no longer need to maintain constant control, there may be a chance that you will not only grow and develop but possibly even gain new abilities. Some possible abilities that you might gain as a result may include shape-shifting while outside of your host, the ability to form a biological armour to protect your own host, the ability to alter your host's body to better suit your needs or even…"

"W-Whoa there, Izuku! Slow down a bit!" exclaimed Sumomo who then said, "Let's not get ahead of ourselves here. Sure, I might be changing a bit but that's no reason to assume that I'll change even more in the future or… or…"

"Regain your original body?" asked Izuku. Sumomo nodded with a troubled expression on her face. Izuku smiled reassuringly and said, "Sumomo-chan, listen to me. Ochako-chan, Tsuyu-chan and I all love you and we won't care if you somehow regain your original body."

"But what if I can't help you find the spy after I regain my body? What if… things turn bad between the three of you because I'm no longer a brain-jacking slime that keeps everyone together due to being my useless original self?" asked Sumomo who had an unmistakably sad expression on her face. It was apparent that she had a low opinion of her past self due to years of abuse.

"Sumomo-chan, had you never entered our lives, I would not have even known how much Ochako-chan and Tsuyu-chan actually cared for me much less loved me. You have done much more good for us than you probably even realise," said Izuku who then added, "Besides, you of all people should know that we'll never think that way about you."

Well-aware of Izuku's past as a quirkless boy and his downright heroic nature, as well as Ochako and Tsuyu's overall good nature, Sumomo knew that he was being completely honest with her. However she was still afraid of the possibility of becoming human again. Sensing her fear, Izuku said, "No one is forcing you to regain your original body. If it does happen, it'll either be because it is unavoidable or, just as likely if not even more so, you have accepted being your original self again."

In spite of her lingering fears and insecurities, Sumomo smiled and said, "You really are a hero at heart, you know that?"

"Well, I do want to be a hero who can save people with a smile just like All Might after all," replied Izuku who was smiling bashfully before he asked, "So… do you want me to hug you before we go?"

"I would like that… very, very much, Izu-kun," said Sumomo.

Izuku smiled at the nickname she had just given him as he gave her a warm and loving hug which she tried to return in kind with an adorably small pair of stubby protrusions that were supposed to be her arms before she had to return back into his head. Before long, Izuku started his day at U.A. High School together with his classmates…

--A short while later…--

Toshinori blinked when he saw Mina and Tooru running away from Izuku, Ochako and Tsuyu during training. He then turned his attention towards Shouta who was standing beside him and asked, "Are they doing some kind of special training by any chance?"

Shouta huffed irritably as he explained, "Hardly. They're just upset that Tooru had spied on them yesterday and Mina sent a message to everyone in class about Izuku's, and I'm quoting here, 'really big boy that is over seven inches long and doesn't go down even after releasing a load'."

Toshinori blushed at the obvious innuendo and said, "Ah, that explains why they're chasing after the two of them." He then noted that Mina and Tooru were pulling off some impressive moves to avoid getting captured by Izuku, Ochako and Tsuyu who were determined to get back at them. He could not help but smile as he commented, "Silliness aside, they're doing surprisingly well all things considered."

"Nothing like running or fighting for your life to develop some new moves," agreed Shouta who smirked as Tooru's invisible body started to refract light that was passing through it to blind her three pursuers while Mina used her corrosive acid quirk so that she could literally run up a steep incline to the top of a towering rock formation.

Although stunned, Izuku, Ochako and Tsuyu quickly regained their bearings and Tsuyu's eyes began to take in infrared light as she sought to find Tooru. She then disappeared as her skin colour and body temperature changed to match with her surroundings.

Ochako on the other hand used her zero-gravity quirk to make Izuku weightless and threw him upwards so that he could catch up with Mina. Upon seeing the incoming human projectile, Mina used her acid quirk to literally create a narrow hole beneath her feet and escape.

Undeterred, Izuku delivered a strong kick to shatter the weakened rock formation, forcing Mina to jump out to escape. Ochako then shouted, "Deku, I'm going to release you!"

Izuku knew what Ochako meant and said, "Do it, Ochako-chan!"

Since Izuku knew what she was about to do, Ochako pressed her fingers together to deactivate her zero-gravity quirk so that Izuku would not float into the sky. Gravity quickly took hold of Izuku but he was prepared for it so he landed safely onto the broken rock formation and quickly sped off to catch Mina. Ochako quickly followed Izuku's lead to capture the pink girl.

Realising that she was about to be captured, and determined to avoid retribution from Ochako and Izuku, Mina created a veil of acid to both distract them and block their line of sight. To counter Mina's defence, Izuku leapt over the veil and quickly tried to grab her to stop her escape. In his attempt to grab Mina, he accidentally tore her skin-tight bodysuit thereby exposing her naked lower half for all to see. His keen observational skills made him realise that Mina had a rather nice bottom which was probably due to being both a dancer and a hero-in-training.

A moment of awkward silence passed before Mina blushed and screamed at the top of her lungs while hiding her naked girly bits.

Izuku immediately prostrated before Mina and apologised, "I-I-I'm so sorry for ripping your suit, Ashido-san!"

Shouta sighed at the ridiculous turn of events and then said, "Ashido, you're excused to leave and get yourself properly dressed. Uraraka, go with her to make sure she gets changed 'unmolested'. As for you, Midoriya, I know that this mess is an accident but do let go of that ripped piece of bodysuit and get back to training."

All three students quickly followed Shouta's instructions and Izuku handed the ripped piece of bodysuit to Ochako who followed Mina to the changing room. Mina was blushing with tears welled up in her eyes as she thought, "H-he's the first boy to ever see my naked butt and girly bits up close!"

--In the girl's changing room…--

Both Ochako and Mina were in the girls' changing room when Ochako placed her arms akimbo and said, "This wouldn't have happened if you hadn't decided to tell everyone in class about Deku's boy bits, you know?"

Mina pouted at Ochako and argued, "You of all people should know that I love hearing romantic stories. How can I not be curious about what you three are doing especially after you had sex right above my room?"

"And what does that have to do with telling everyone in class?" asked Ochako who was still frowning at the acidic girl while also sporting a blush as she could not refute the fact that she and Tsuyu had sex with Izuku directly above Mina's room.

Mina had the decency to be sheepish as she answered, "Okay, I'll admit that I probably should have kept it to just the girls in our class but the only girls who did not know at the time were Jirou-chan and Yaomomo. Besides, even Todoroki-kun seemed curious about Izuku."

Ochako raised and eyebrow and asked, "Seriously?" She knew from sharing memories with Izuku that the green-haired boy was clearly heterosexual and only saw Shouto as a friend and comrade.

"I'm serious. He was about to raise his hand during the vote to see Izuku's dick before he decided against it," said Mina.

Ochako sighed and decided not to argue about the matter further as she spoke to Mina, "You did tell them not to spread that information to the rest of the school at least, right?"

Mina suddenly paled and looked away from Ochako as she admitted, I… might have forgotten to add that part…"

Ochako was ready to throttle the pink-skinned girl but Sumomo intervened and mentally reminded her, "You do remember that I'm supposed to brain-jack Ashido-san and the other three girls in Class 1A to determine if any of them is the spy right? This is as good an opportunity to brain-jack her as any."

Upon hearing Sumomo's reminder, Ochako had an idea. An almost villainous smirk formed on her face as she got closer to Mina and said, "Say, Mina-chan, you wanted to know how Deku, Tsuyu-chan and I got together, right?"

"Y-yes, I do want to know," replied Mina who did not like the look in Ochako's eyes and nervously backed away from her.

Ochako slowly cornered the nervous pink-skinned girl and said, "Well, the thing is, Tsuyu-chan and I had a bit of… help in confessing our feeling for Deku."

Mina's back was pressed against the wall when she asked, "H-help you say? So, who was the one who helped you?"

Ochako placed her hands onto the wall to prevent Mina from escaping and moved in to whisper into her ear, "I'm about to tell you."

Suddenly, Mina felt something slimy enter her ear and, before she could even cry out for help, her body was immobilised. Mina's eyes rolled back while drool started to flow from the side of her mouth and her body twitched in a futile attempt to fight off the parasitic takeover of her body. Panic started to swell in her chest when she heard Ochako's voice in her head, "While Sumomo-chan is looking through your memories, I'll show you what really happened between Tsuyu-chan, Deku and me."

Mina was about to ask Ochako what was going on when she saw Ochako's memories of what had happened to her, Tsuyu, Izuku and the slime girl named Sumomo. Although there were parts that were left out, including most of Sumomo and Izuku's backstories, details on One For All and Ochako's sexual experiences with Izuku, Tsuyu and Sumomo, Mina saw more than enough to realise that she was in no real danger from the brain-jacking ex-villainess. By the time Sumomo had finished looking through Mina's memories and verified that she was not a villainous spy or even a sleeper agent, she was calm enough to not "totally flip the heck out" when she regained control over her own body in spite of having Sumomo's copy in her own head.

"Wow, this situation feels like the kind of crazy story a horny bugger would cook up to fulfil his sexual fantasies," said Mina.

Ochako could not help but chuckle in agreement and said, "Well, it can't be any worse than the kind of sleazy porn Mineta's bound to have in his collection."

"Oh, I won't doubt that," said Mina who then added, "So, how do you plan to get the others?"

Surprised by Mina's inquiry, Ochako raised an eyebrow and asked, "You do realise that we're essentially going to let Sumomo-chan brain-jack the others in our class, the girls Class 1B and possibly even other people like Midnight-sensi, right?"

Mina shrugged and said, "Look, if this crazy harem plan works, we'll be able to stop the League of Villains from attacking us again like back at summer camp. Besides, this is Nedzu-sensei's plan so it has to have a pretty good chance of being a success."

"And you're not against the idea of being a member of Deku's harem?" asked Ochako.

"Well, I'll have to get to know him more to really decide if I want to be in his harem. Besides, I don't have a boyfriend at the moment and I'm pretty sure that Tooru-chan, Jirou-chan and Yaomomo are still single too," explained Mina.

Recalling the girls' discussion on boyfriends back at summer camp, Ochako had to admit that Mina was not wrong. Nevertheless, Ochako had to ask her, "But what about Kirishima-kun? He's known you since middle school after all." Indeed, as Ochako recalled from previous conversations with Mina, the pink-skinned girl and Eijirou had actually known each other since middle school.

Mina smiled and admitted, "We certainly have known each other since middle school, but that's exactly the reason why I know that he's not interested in being my boyfriend. He wants to be a great hero who never has any regrets and I doubt he'll even think about dating until he achieves that dream."

Ochako frowned and asked, "Deku wants to be a great hero too but that didn't stop him from developing feelings for me even before Sumomo-chan came into the picture."

"True, but I get the feeling that he's more into bromance rather than romance. Also, while he's undoubtedly a good friend and fellow hero-in-training, he's not really my type as a boyfriend," explained Mina.

Deciding to trust Mina's judgement, especially since Sumomo had said nothing to contradict her claims even after looking through her memories, Ochako said, "Well, if you say so, I suppose you can be a part of the harem. Just know that you don't have to join us immediately and you can even back out of it if you want. Trust me, there'll no turning back or backing out once you look into Deku's memories."

Mina nodded and said, "I'll keep that in mind, Ochako-chan."

--Later that day…--

Izuku had just finished his training and was walking towards the support department workshop to find out if Mei had made any progress on the requested support items. As he made his way to the workshop, he heard another loud explosion and sighed as he understandably assumed that one of Mei's experimental support items had blown up, again.

In spite of his exasperation, Izuku quickened his pace to reach the workshop which was clearly smoking. He could also hear the exasperated yelling of a short and skinny man with spiky ginger and dull blue eyes hair named Maijima Higari. Also known as the pro-hero, Power Loader, Higari was yelling at Mei for creating yet another insane invention that had exploded. Izuku hesitantly asked the irate teacher, "Excuse me, Power Loader-sensei. Is now a bad time for me to be here?"

Noticing the boy, Higari replied, "That depends on whether you're here for business or for socialising."

Well-aware that Higari was in no mood to put up with anyone interrupting him to socialise with the apparently unrepentant Mei, Izuku quickly answered, "I'm here for business with Mei. My friends and I requested her to make some support items for us."

"Friends as in girlfriends?" asked Higari.

Surprised, Izuku blushed and asked, "E-excuse me?"

Higari took out his smartphone and said, "There's no point in hiding it, Midoriya." He then showed Izuku a message as he added, "Even as we speak, news of your girlfriends and your… impressive genitalia are making the rounds in the entire school to the point that even the teachers got word of it as spam."

Izuku made a comically high-pitched noise which sounded similar to a cat which was receiving a colonoscopy as he read the message that stated, "Big news, everyone! Thanks to certain sources from our insiders in Class 1A, we now know that Izuku not only has TWO girlfriends but also has a member which is over seven inches long and stays hard even after releasing a load! He has the face of an innocent boy and yet has the sex drive of a beast!"

Forgetting his place as a student, he quickly snatched the phone from Higari's hand and continued staring at the damning message as he fearfully asked, "Does… Nedzu-sensei know about this?"

"Knowing him, he probably knew about it long before the message started to spread around the school," replied Higari who did not mind Izuku snatching his phone in an understandable moment of panic.

Izuku's shoulders slumped in comical despair as he muttered, "N-no wonder everyone in school has been staring at me today." While the boys stared at him with amazement, envy or even admiration, the girls stared at him as though he was a lustful beast to be avoided or a piece of meat to be "devoured". He then fell onto all fours as he added, "M-my mom's going to disown me and then kill me when she finds out about this. Or tease me to death which might just be worse."

Higari bent down to console Izuku, as well as retrieve his smartphone, and said, "If it makes you feel any better, the principal is doing what he can to keep the damage on your reputation, as well as the reputations of your girlfriends, to a minimum." He then grinned and said, "Besides, scoring two girls at the same time after what you all went through back at summer camp is hardly the worst sexual scandal the hero world has ever known."

Izuku found the willpower to stand up and said, "I just hope that this… mess will die down soon."

"Provided that you stay faithful to those two girls, I'm pretty sure that the worst of the rumours will die down before long," said Higari who failed to notice Izuku's slight flinch at the statement. Considering the Harem Plan, Izuku had every reason to worry that his growing infamous reputation as a lustful beast would not die down any time soon.

"Anyway, I've already taken more of your time than necessary so I'll let you take Hatsume off my hands for a while," said Higari who then whispered in a conspiratorial way, "By the way, if you don't mind me making a request, please help me to convince that idiot to stop blowing up the workshop. She has caused more explosions than all of her peers combined!"

"You're… not seriously telling me to use my 'manly charms' on her, are you?" asked Izuku who noted the irony that Higari was essentially telling him to take in Mei as a harem member after she already knew about the Harem Plan.

"Honestly… yes, I am," admitted Higari who then explained, "Make no mistake, she's a great inventor but I'll rest a lot easier if I know that she has someone to keep her from blowing stuff up all the bloody time."

Izuku chuckled sheepishly and said, "Well, I can't make any promises but I'll see what I can do. In return, do you think you can help with the rumours?"

"That depends, do you and your girlfriends love one another?" asked Higari.

Izuku had a firm, confident and downright heroic expression on his face as he answered, "We do, Power Loader-sensei. It may have taken the attack during summer camp and the Kamino Incident for the two girls to finally decide to tell me their true feelings for me but I am truly glad that we got our feelings across."

Higari smiled at Izuku and patted him on the shoulder as he spoke, "Then I'll do what I can to convince everyone that those two girls have a damned good reason to be your girlfriends."

"Thank you, Power Loader-sensei," said Izuku who gratefully bowed to Higari.

"Think nothing of it," said Higari who then pushed Izuku towards Mei and said, "Now, go and find out how much progress Hatsume has made with your support equipments."

Mei was all too happy to show off the progress that she had made to Izuku as she quickly grabbed onto him and then dragged him to her corner of the workshop. He soon found out that Mei would be able to finish some of the requested support equipment by the end of the day and would personally deliver the goods to the girls' side of the Class 1A dorms. The boy could not help but blush as he knew that she would soon learn more about him and possibly decide to become an official member of his harem.

--Meanwhile…--

Tooru recently received a message from Mina to meet her in a secluded part of the school to discuss on how to settle things peacefully with Izuku, Ochako and Tsuyu. Considering her role in spying on the three of them while they were sexually pleasuring one another, Tooru knew better than to ignore such a discussion. She had barely avoided Tsuyu who could not only camouflage herself but even detect infrared light which essentially gave her heat-detecting abilities. Although Tooru was undoubtedly invisible, she could do nothing about concealing her own body heat. The invisible girl shuddered as she recalled how Tsuyu kept on chasing after her like some sort of unseen persistent predator. It was a small miracle that she was able to escape Tsuyu's grasp.

Before long, she saw Mina who was waiting for her at the meeting place and said, "Hey, Mina-chan. You wanted to discuss with me on how to settle things peacefully with those three love birds, right?"

Mina nodded and explained, "The good news is that I have an idea on how to settle things peacefully."

Tooru tilted her invisible head and asked, "And the bad news?"

Mina did not react to the downright terrifying sight of Tsuyu emerging from "camouflaged hiding" directly above Tooru with her long tongue extended as she sheepishly smiled and replied, "Well, it involves getting an earful of slimy wing-wong."

"Wait, what?" asked Tooru before Tsuyu suddenly seized her with her tongue which was coated with a slimy copy of Sumomo…

--Elsewhere…--

Momo and Jirou were making their way to class when Ochako stopped them and asked, "Jirou-chan, Momo-chan, can I have a word with the both of you?"

Surprised by Ochako's sudden request, both girls had no reason to reject it as Momo replied, "Of course, you can. Is something the matter, Uraraka-san?"

Ochako smiled sheepishly as she scratched the back of her head and explained, "Well, it's not something to be discussed in public."

Jirou blushed as she wore a deadpan expression and asked, "It's nothing to do with your love life, does it? If it does, count me out!"

Embarrassed by Jirou's response, Ochako waved her hands to dispel the implication and said, "N-no, it's nothing to do with my love life! I just want to talk to you two about some things in private, that's all."

Jirou raised her eyebrow sceptically while Momo readily accepted Ochako's request, "Well, it if is something not related to lovema…" Momo coughed before she corrected herself, "-love, I suppose we can afford a few minutes to help you out."

"Great!" said Ochako who then turned around and beckoned the two other girls to follow her.

In spite of her doubts, Jirou decided to tag along with Momo as they both followed Ochako to a secluded part of the school. Once they arrived at the place, which was an unoccupied science laboratory, Ochako closed the door and said, "Thanks coming to hear me out."

"It's no trouble at all, Uraraka-san," said Momo who then added, "As the vice representative of Class 1A, it's only natural for me help my fellow classmates in any way I can."

Jirou shrugged and said, "Your love life aside, you're still a friend of ours so of course we'll help you out if you need it."

Ochako smiled gratefully and said, "Thank you, it means a lot of me."

"So, what do you need help with anyway?" asked Jirou.

At that moment, two blobs of pink slime landed onto Jirou and Momo's heads…

--Later at the dorms…--

Izuku, who was helping Mei to deliver some support gear to the girls of Class 1A, blinked in surprise as he stared at all six of his female classmates who had gathered in Ochako's room and asked, "How did you two manage to get all the others on the same day?"

"Well, after I 'convinced' Mina-chan to join us, Mina-chan and Tsuyu-chan worked together to convince Tooru-chan while I had a word with both Momo-chan and Jirou-chan," explained Ochako.

Jirou wore an annoyed expression as she added, "Ochako-chan got us real good. We didn't even get to say no before we were convinced to give you and this crazy Harem Plan a chance."

"To be fair, I couldn't have done the double brain-jack without completely evacuating from Ochako-chan and splitting that copy into two. The only reason why I can even consider doing such a thing is because I trust her completely," said Sumomo who was mentally communicating with everyone present in the room.

Izuku knew that the girls were deliberately avoiding mentioning about Sumomo to prevent anyone from finding out about the brain-jacking slime girl. He then recalled what Sumomo had done to him, Ochako and Tsuyu earlier that day and mentally spoke to her, "Sumomo-chan, I think you should stay hidden and not leave our heads too often. The last thing we need is you being discovered by someone whom we cannot fully trust."

Sumomo's mental image nodded in understanding and said, "I understand, Izu-kun."

"Still, I never expected you three to be forming a harem of all things," said Momo as she placed her hand onto her cheek in a ladylike manner and then mentally added, "Or the fact that your love lives were actually improved by a brain-jacking ex-villainess. No offence meant, Yamanaka-san."

"None taken, Mo-chan," said Sumomo who then mentally spoke to Izuku, "That said, we managed to find a lead on our objective."

"Really, who?" asked Izuku as he handed the support gear to the girls.

"It's not really a who but rather a what," said Sumomo who then explained, "It seems that Tooru-chan's parents requested a trusted family doctor to implant a tracking device into her body so that they could get someone to track her down in case anything bad happens to her such as getting kidnapped by a villain. Considering her invisibility quirk and the USJ Attack, I can't really blame them for making that decision and I can't imagine them knowingly doing anything that would harm her unless they are forced to do so."

Izuku nodded slightly and mentally said, "I understand. There is a chance that this could be a false lead but we do need to be sure about the tracking device is not being used by the League of Villains or any other villainous groups."

"Which is why Tsuyu-chan quickly reported the matter to Nedzu-sensei after I had brain-jacked Tooru-chan," said Sumomo.

"Hopefully, that will settle the issue. I'd rather not have to drag in any more people into this," said Izuku.

"Kind of too late for that, don't you think?" asked Sumomo.

Izuku smiled sheepishly and said, "Maybe, but in my defence this is mainly Nedzu-sensei's idea."

"Speaking about Harem Plans, I think we should start discussing about this crazy idea of yours, Midoriya Izuku," said Mina who had a cheeky grin on her face.

"That's right, are you seriously going to form a harem?" asked Jirou.

Izuku blushed and bashfully replied, "Well, I'm already in a relationship with Ochako-chan and Tsuyu-chan so none of you have to actually join the harem if you don't want to." He then mentally added, "You're in the harem too by the way, Sumomo-chan."

"I know, Izu-kun" replied Sumomo.

Momo, Jirou, Tooru and Mina looked at one another for a moment and then turned their attention towards Izuku. Mina was the first to speak as she shrugged and replied, "Well, none of us has a boyfriend at the moment. Heck, I didn't even think about getting a boyfriend up until recently."

"Really?" asked Izuku who was surprised by the answer.

"The other boys in our class are generally good friends and comrades but… let's just say that we have our reasons for not considering them, as well as you, as boyfriend material," explained Momo who then added, "Prior to… recent events, only Uraraka-san and Asui-san even considered you as a possible boyfriend, Midoriya-san."

Izuku recalled Ochako and Tsuyu's conversation with the other girls of Class 1A and even three girls from Class 1B about boyfriends during summer camp. Blushing at the realisation that he might be the only sexually attractive boy in the whole class, at least as far as Mina, Tooru, Momo and Jirou were currently aware off, Izuku bashfully asked, "So… you're okay with getting to know me?"

"Considering that none of us have a boyfriend and your… sexual acts have gotten us hot and bothered lately, I'd say that we have nothing to lose in getting to know you," said Jirou. The other girls, including Mei, nodded in agreement with Jirou.

Seeing no reason to delay any further, Izuku sat down and said, "All right then, you might want to get comfortable. This could take a while."

--One memory share later…--

"H-holy shit…!" swore Jirou as tears fell from her eyes. Prior to the recent memory-sharing, Mei, Mina, Tooru, Momo and Jirou were not informed of certain details such as Izuku and Sumomo's full backstories and the details of One For All. Needless to say, all five of them were shocked by Sumomo's terrible past which drove her to villainy and Izuku's cruel abuse due to being quirkless. They also quickly understood why both Ochako and Tsuyu became so cold if not hostile towards Katsuki lately and, honestly, none of them could blame the two girls. In fact, their opinion of Katsuki had fallen so much that he was deemed as basically no better than Mineta as far as they were concerned.

Considering that Katsuki had spent years bullying Izuku for being quirkless and even went so far as to suicide-bait him, the girls felt justified in thinking that he was no better than the worst pervert they had ever known. They knew that any hero worth his salt would not be a cruel bully who picked on the weak.

Feeling mentally and emotionally drained, the girls were in no mood for anything other than rest, preferably with plenty of warm cuddles. Even Mei was affected by the urge but she had something else which was even more urgent in mind as she stood up and spoke with uncharacteristic seriousness in her voice, "Everyone, please read the instructions on how to use the babies that I have made for all of you. If you have any questions, feel free to ask me tomorrow. I'll also let all of you know as soon as I'm done making the other babies."

"Do you need to go somewhere, Hatsume-san?" asked Izuku.

"Let's just say that I… might need help in improving my babies," said Mei who then added before she left, "Also, count me in as a harem member, Izuku."

Although the others were not aware, Sumomo knew what Mei actually wanted to do and mentally asked her, "You're going to ask Nedzu-san to have 'her' come here and possibly have her join the harem, aren't you?"

Mei left Ochako's room as she mentally communicated with Sumomo, "That's right. Izuku'll need all the help he can get if he's going to be the next heroic symbol of the world. We need her expertise and we both know that Izuku's too pure-hearted to even consider such an idea on his own."

"Considering her relationship with All Might-san, it'll be best that he's informed about your idea too before Nedzu tries to invite her. The last thing we need is an overprotective former hero going after our collective butts," said Sumomo who did not want to even think about an angry All Might going after her and her hosts. Retired hero or not, Sumomo did not want to risk getting "United States of Smashed" into the next century.

"No argument there," agreed Mei.

While Mei left the dorm, she caught sight of Katsuki and threw a dirty look at him before she left. Her angry look did not go unnoticed as Eijirou blinked at her and asked, "Hey, Bakugou, did you blow up one of her inventions or something?"

Katsuki was "somewhat blissfully" unaware of how badly the girls of Class 1A and Mei viewed him as he angrily replied, "No, I didn't do shit to Goggle's stuff."

--Back to Izuku and the girls of Class 1A…--

"So… I'm assuming that you all want to join the harem too?" asked Izuku.

"Considering everything that you have revealed to us, I think it is a safe to say that we're all interested to give this harem lifestyle a try if nothing else," admitted Momo. Much like the other girls, she was awed by Izuku's heroic nature in spite of his past suffering and she knew that he would make a great hero. There was also the fact that Izuku was apparently incredible in sex which was an admittedly appealing bonus.

Izuku blushed at the thought of being sexually intimate with the other girls in his class as he asked, "Well, if you don't mind, I would like to have a word with Hagakure-san alone. Is that all right with all of you?"

Realising why Izuku wanted to have a word with Tooru alone, none of the girls protested although they were disappointed that Izuku would be spending time with her, especially Ochako and Tsuyu. Tooru on the other hand was surprised that Izuku wanted to spend time with her alone but she did not refuse as she led him to her room.

Before long, Izuku was alone with Tooru in her room and he asked her, "Are you… all right Hagakure-san?"

"Well, considering everything that has happened today, I'm doing okay I guess," replied Tooru who was lacking her usual upbeat attitude.

Concern was evident on Izuku's face as he asked, "You're worried, aren't you?"

Well aware that Izuku had seen her memories, Tooru meekly nodded and said, "Considering that I might have played a role in bringing those villains to summer camp…"

Izuku gently yet firmly placed his hands onto her shoulders and said, "Listen to me. No matter what Nedzu-sensei finds out about that tracking device, please know that this is not your fault. Your parents asked that doctor to put that tracking device into your body for the sake of being able to keep track of you in case anything bad happens to you. The only ones who deserve the blame are the villains who have taken advantage of it and that's assuming that they have actually done it somehow."

Tears welled up in Tooru's eyes as she hugged herself and argued, "But if my tracking device was used by the villains to find us during the summer camp, that means that Ragdoll's loss of her quirk, Katsuki's kidnapping and everyone's injuries were all because of it." Her tears fell as she started to sniffle, "H-how can I face everyone and still be happy as though nothing is wrong after knowing that my parents and I have basically allowed the attack to happen? I… don't even know hot to start atoning for what I have allowed to happen."

"Hagakure-san, please look at me," said Izuku.

Tooru hesitantly looked up into Izuku's eyes and saw only kindness and concern in them as Izuku continued to speak, "I was among the people who got badly hurt in the attack but I refuse to blame you for something which you have unknowingly done. You're my classmate and a close friend of both Ochako-chan and Tsuyu-chan who also don't blame you for the attack."

Tooru became even more upset as she slammed her clenched fists into Izuku's chest while yelling at him, "T-that's the thing, you selfless idiot!" She shook with barely-repressed emotions as she continued to yell, "Y-your arms… that boy, Kouta… if things had gone even a little bit differently, both of you and so many others would have died! I… I shouldn't have become your classmate! I should have just accepted what everyone said about me being invisible and…"

Tooru's rant was cut short when Izuku suddenly hugged her closely and gently patted her head with his scarred hand. He then said, "Please, don't ever think that you're not worth anything." Thanks to the memory-sharing, Izuku knew that Tooru had a fear of living her life being unnoticed and alone due to her invisible nature. The prejudice which she received due to her quirk only made her hidden fears and insecurities worse. As someone who was deemed as worthless due to being quirkless, Izuku knew what it was alike to be treated as though his very existence did not matter to anyone and he refused to allow Tooru to think way about herself.

Unable to hold back her emotions, Tooru cried.

--Some time later…--

"Hagakure-san, do you feel any better now?" asked Izuku who was sitting on Tooru's bed with the invisible girl by his side. His arm was draped around the girl's shoulders in a comforting manner.

Tooru nodded in spite of being invisible and said, "Thank you… De-kun. I really needed someone to cry on."

Izuku smiled kindly to her and said, "It's the least I can do to help you…"

"Tooru. You can call me by my first name, De-kun," said Tooru.

Realising that he had permission to call Tooru by her first name, Izuku nodded and said, "I understand, Tooru-chan."

Tooru's blush would have been clear for all to see if she was visible as she hesitantly replied, "Say… De-kun. If I'm a part of your harem, does that mean we can… have sex?"

Izuku blushed as he replied, "Well, we certainly could." His expression became serious as he added, "But do you really want to? I don't want you to have sex with me just because you feel obligated to repay me for forgiving you or because you need something to stop the pain. Trust me on this, having sex for just those reasons don't usually end well."

Sumomo's mental image nodded in agreement with Izuku as she spoke, "He's right you know. If you're going to have sex with Izu-kun, do it because you actually like him as a person, not because he's the easiest source of comfort to get."

Smiling in spite of being invisible, Tooru admitted, "I admit that I want to be comforted and I am grateful for your kindness and forgiveness, De-kun." She then reached out and kissed Izuku tenderly on the cheek before she added, "However, I also like you as a person and I know for a fact that you will treat me and the other girls in the harem right."

Realising that Tooru was serious, Izuku's blush deepened and said, "If that is how you really feel about me, then I'll try to be as gentle as I can, Tooru-chan.

Tooru nodded and then started to remove her clothes. Izuku quickly removed his own clothes and the both of them were soon naked. While Izuku was essentially staring at seemingly empty air, Tooru was staring at his naked body with a mixture of awe for its masculine appeal and regret for the scars of his damaged arms. Izuku then asked, "So… do you want me to be on top or do you want to be the one on top?"

"L-let me be the one on top," said Tooru who the added, "My naked body might be… difficult to get used to."

Izuku nodded and lay back on the bed. He soon felt someone getting on top of him and he asked, "Tooru-chan, are we facing face to face?"

"Yes, we are," replied Tooru.

"Then, please excuse me," said Izuku before he reached out to told her. As soon as he got hold of her face which had soft cheeks, he started to gently trace his fingers on other parts of her upper body including her short hair, shoulders, neck, ears and breasts. The invisible girl shivered in pleasure as he gently fondled her soft breasts and teased her erect nipples. Her breath grew heavier and her nether part became moist as Izuku proceeded to stroke her flat stomach, backside and thighs.

As for Izuku, he felt increasingly aroused as, in spite of being unable to see Tooru, he could still touch, smell and hear her. His growing arousal became apparent as his penis became fully erect and started to twitch while pre-ejaculate leaked from the exposed tip of his glans.

Unable to bear the growing desire in her loins any longer, Tooru said, "De-kun, I'm going to put your… big and stiff thingy in."

Izuku nodded in understanding and almost gasped as he could feel a warm yet unseen hand guide his phallus towards what he assumed to be Tooru's invisible maidenhood. Soon, he felt his member entering her sacred place and he knew that Tooru was struggling as he could hear her holding back gasps of pain. He was about to ask her if she wanted him to be on top when she suddenly forced her hips downwards so that his penis could enter her fully. Tooru barely held back a scream of pain as she gripped onto the sheets of her bed tightly and gritted her teeth. As the pain slowly subsided, she started gasping and was struggling to support herself so Izuku placed his hands below her armpits to hold her up.

"A-are you all right Tooru-chan?" asked Izuku who could see blood on his still-visible phallus and was worried that he had caused her great harm.

"I-I'm okay, De-kun," said Tooru who then asked, "You do realise… that your hands are under my armpits, right?"

Izuku blushed and sheepishly replied, "I kind of suspected it but I didn't think that was important at the time."

Tooru chuckled at Izuku's still-innocent nature and said, "I'm all right now. You don't have to hold me up while I move, De-kun."

"Maybe so, but I do want to continue holding you and touching you, Tooru-chan," replied Izuku who then added, "I might not be able to see it but I can tell by touch alone that you are beautiful." He was being honest as he could feel her soft yet firm body, smooth skin and delicate bone structure.

Tooru felt her heart swell with joy as she had longed to hear someone compliment her looks in spite of being invisible. She then lowered herself so that she could kiss Izuku on the lips. Although Izuku was initially surprised, he soon gladly accepted her kiss as he placed his hand behind her head so that he could kiss her more deeply. After what seemed to be a mere moment, the two of them parted their lips to breathe and looked at one another longingly before Tooru started to move her hips.

In spite of the pain, Tooru also felt pleasure as she could feel Izuku's member reaching deep inside of her. As Tooru moved with increasing speed and passion, Izuku started to move his own hips to match with her movement while his hands held onto her slim waist. Tooru's sweat formed a rough yet erotic outline of her sensual body as she started to sway her hips to fully enjoy the feeling of Izuku's member moving about in her nether part. Soon, the two lovers were close to climax and Izuku said, "T-tooru-chan, I'm going to cum soon!"

"I had my period yesterday so go ahead and do it!" said Tooru who knew enough about the female reproductive cycle to know that that day was her save day. The movement of her hips quickly accelerated as she too was close to climax.

Reassured by her statement, Izuku climaxed and ejaculated deep inside of the invisible girl who could feel his hot seed filling her insides. As Izuku recovered from his orgasm, he idly noted that he could see his ejaculate filling up the inside of Tooru's twitching vagina and even leaking into her womb. The sight turned him on and his still-stiff member twitched in response to his sexual desire.

Surprised by the twitching sensation, Tooru had to ask, "So… how many times do you have to cum for your thingy to calm down?"

Izuku blushed and avoided Tooru's invisible yet undeniably inquisitive gaze as he replied, "I honestly don't know but I think I can cum at least three more times."

Tooru blinked and said, "I hate to break it to you, but I just came and don't think my girly bits can take much more of it today."

Knowing that Tooru had just lost her virginity, Izuku was about to reassure her then they both heard the door open. Both lovers were shocked as Ochako, Tsuyu, Mina, Jirou and Momo entered the room with bright-red blushes on their faces. Their blushes only grew when they could see Izuku's phallus which was still inside Tooru's ejaculate-filled vagina.

Izuku was filled with both fear and excitement as he asked the five other girls, "Do you… want to have sex too?"

All five girls nodded and Jirou glared at Izuku as she spoke, "You are so taking responsibility for making us so… so damn thirsty for sex!"

"Not that I mind having you girls take over, but my bed's not big enough to fit everyone," said Tooru.

Mina grinned in an almost predatory way as she replied, "Nothing that a few adjustments can't fix!"

As if sharing one mind, Mina, Ochako and Jirou went to fetch Jirou's mattress, pillow and blanket while Momo went to Tsuyu's room to get some spare IUDs. Unlike Tooru, Momo wanted to make sure that everyone who wished to have sex with Izuku were properly protected.

Seeing the girls set off, Izuku sighed with a smile and his face while Tooru pulled herself off his erect phallus. Sumomo used that moment to leave Tooru's head and oozed her way into her sore private part to feed on Izuku's ejaculate. Safe day or not, it never hurt to make sure that an unwanted pregnancy would not happen.

"De-kun?"

"Yes, Tooru-chan?"

Tooru leaned against Izuku's solidly muscled form and said, "Thank you… for being a good friend and lover."

Izuku smiled in response and nuzzled against her head affectionately as he replied, "You're welcome, Tooru-chan.

Although the two lovers knew that the peaceful silence would soon end due to the other members of Izuku's growing harem wanting a piece of the action, they did not mind it the least as they simply enjoyed being close with one another.

--Meanwhile…--

"I must admit, I never expected you to make such a request, Hatsume-san," said Nedzu who was smiling at Mei who stood before him in his office. He then asked her, "So tell me, why should I invite Melissa Shield into U.A. High School when she can receive better technological support and security from I-Island?"

Mei had a determined look on her face as she spoke, "That's because she's the only one who actually created something that could protect Izuku's arms from getting damaged by his own quirk which, by the way, we both know he was not born with." She stepped forward as she added, "Even if the Full Gauntlet was destroyed in the end, the fact that it could protect Izuku from damaging his own arm while he used the full power of his quirk for up to three times is more than enough reason for any sane individual to realise that she's a bloody genius." Mei stood across Nedzu's desk and slammed her hands onto it as she spoke, "As much as it pains me to admit it as an inventor, I need her help to make the kind of support gear that Izuku will need to have until his body is able to handle that ridiculously powerful quirk without destroying his own body in the process." Her eyes bore into Nedzu's own eyes as she asked, "So, can you do anything to help us?"

A tense moment of silence passed before Nedzu smiled and accommodatingly replied, "I would need to have a word with All Might about the idea of having Melissa join the harem. However, given your convincing argument and certain… complications that have arisen due to her father's misguided actions during this year's I-Expo, I believe I will be able to bring her to U.A. High School as a transfer student of the support department. I will let you know by tomorrow, Hatsume-san."

Mei smiled and replied, "Thank you, Nedzu-sensei. You won't regret it!"

"Just be sure to let Izuku and the rest of his harem know about Melissa's arrival after I have confirmed her transfer," said Nedzu.

"Will do, Nedzu-sensei," said Mei before she left the office to return to her room.

After Mei left, Nedzu could not help but chuckle as he thought, "What an interesting turn of events. To think that the infamous 'mad inventor' and 'shameless advertiser' of the support department would actually go so far for the sake of helping Midoriya after joining his harem. I seems that I have actually underestimated your ability to impress the ladies, Midoriya Izuku. Even I'm no longer certain of what will happen if you continue to make your harem grow." His chuckles turned into a near-mad cackle of glee as he added, "Things are about to get interesting!"

--End Chapter--

Author's Notes:

BNHA has not only an anime series and a manga series but also a series of short stories known as BNHA School Briefs which cover parts of the story not mentioned in the anime or manga such as the girls talking about having boyfriends during the summer camp.

I am writing this story under the assumption that Mina, Tooru, Jirou and Momo do not have any boyfriends or boys whom they are romantically interested in. This assumption is supported by BNHA School Briefs Volume 2 which covers the summer camp discussion mentioned above. Don't get me wrong, I have nothing against Momo, Jirou, Mina and Tooru liking other guys and I'm sure that they would have fallen in love with other boys in the later parts of canon. However, trying to acknowledge the fact that they are interested in other guys in what is basically an Izuku/Harem fanfiction would make things too complicated and drama-filled for my liking. Don't forget, I'm writing this story for erotic smutty fun, not romance-related angst.

Also, in response to some comments from both and , I would like to make a few things clear:

I am NOT going to add EVERY girl in the series into the harem. That said, I am definitely going to add Melissa Shield into the harem (kudos to the commenter who mentioned/suggested her as I actually forgot about her).

At least one more girl will definitely be added into the harem. However, for the sake of avoiding spoilers, her/their name(s) will not be revealed for now. Also, Sumomo does not count as she is already in the harem.

As for the other ladies, including the girls of Class 1B, only time will tell.

By the way, you better believe that Izuku's going to have sex with the other girls in the next chapter!

I hope you all have enjoyed this chapter and look forward to future chapters.

Until next time, go beyond, plus ultra!
