"Hey Izuku."
"Wahhh!" All Might's successor yelped as she was greeted outside the nurse's office by her cru– classmate, Saiki perched on the windowsill waiting for her. She scrabbled to close the door before he could see inside where All Might was still recovering. "Hi! Saiki! Hi! How's it going?"
"I feel like I should be asking you that," he replied in a non-answer. "How are your legs?"
She looked down at her now... mostly healed legs. She raised her crutch in demonstration, "Mostly better? Recovery Girl says it's too much to heal in one go. I have to come back tomorrow to finish treatment."
"Right..."
Izuku fidgeted under the awkward silence, not knowing where to take the conversation from there. Of all her classmates, Kacchan knew her best but she had always been distant despite being childhood friends. Because of that, Saiki was a fairly close second. More than that, he knew more about her quirk than even Kacchan did.
He knew what she did in the USJ made no sense.
When All Might arrived and beat that brain villain it was amazing but she knew his time was up, that the other villains could kill him! She had to step in! Had to act!
… But no one else knew that.
Most of the class had shrugged it off. But not Saiki. He had been giving her strange looks ever since.
"Are you suicidal or something?"
The colour drained from her face at the blunt comment. "No, no, nothing like that!" she frantically waved away the suggestion! "It's just–!" … Just what? What could she tell him? That she was impulsive and rash? The rest of their time in the USJ proved that wasn't the case, not to mention everything else. What good explanation did she have?
His frown deepened at her lack of answer, shaking his head. Suddenly, he was in her personal space and sweeping her into– "Wha–! Again?!" she squealed as she once again found herself in a princess carry! She was suddenly glad she was still in her gym uniform instead of her uniform skirt!
"Should probably keep off of your legs, right?" he asked with a smirk, already headed towards the entrance. "Plus, I was disappointed I didn't get to do this before. What aspiring hero doesn't want a cute girl in a princess carry?"
"What aspiring hero wants to be the–" … Did he just say cute?
"Sorry! This is just what you get when you worry me like you did today!"
Izuku wasn't exactly in good shape to object physically... And it did feel kinda nice... She could hear his heartbeat. Very slow, strangely slow. But steady.
He was so warm.
Without realising it, she was cuddling into that warmth. Because of it, she didn't see Katsumi as the two of them passed her by. She didn't see the dark look Katsumi gave him. She didn't see Saiki's taunting wink.
-(-)-
"Hello?"
"Is that the creeper?"
"... Huh. How did you get this number?"
"That doesn't matter. I'm at that place. Come meet me."
"And I should do that because...?"
"You don't want another wager?"
And that was how Saiki found himself once again traipsing into the woods near the UA campus the day after the USJ attack. The school was closed for the day for the investigation so Saiki was in casual clothes, jeans and a long-sleeved shirt. Knowing where this was going, he carried a backpack with a change of clothes.
Finding Katsumi, he saw she was wearing more hard-wearing attire. Durable fabric more commonly found on construction workers. "Creeper."
"It's tempting to make my demand this time that you have to call me by name," he sighed, then smirked, "Or maybe 'Master'. That could be nice too."
He was trying to get under her skin and he could see from her twitching eye it was working. "Same stakes as last time," she growled, twisting and stretching out her arm and shoulder muscles.
He hummed noncommittally. "I have to admit I'm curious. I didn't think you'd come out and challenge me again. Especially so soon, and going to such lengths to do it. What brought this on?"
"I want you to stay away from Deku," she continued to growl. He really did like her voice, raspy and low, husky. He wanted to hear that voice moan in ecstasy again.
Sadly, or thankfully depending on who you asked, the girl attached to that voice was too straightforward for her own good. "Oh wow, that's adorable! Do I detect a hint of protectiveness for your most hated rival? I didn't expect to see this new side of you, Katsumi!" Just giving up her intentions like that. He shook his head sadly, feigning regret. "Well that's a shame. That's not on the table."
"Bullshit! One demand, whatever the winner wants, that's what you said!" she barked, pointing at him in accusation.
"I did. Those were the terms. Last time. This time, I'm not willing to sacrifice that." He smiled and shrugged helplessly. "Sorry!"
She balled her fists, literally shaking with rage. Her jaw worked, her neck rolled. "What do you want," she demanded as she... Dropped to the floor?
Oh, push ups! That was clever. Working up a sweat before the fight started.
Saiki tapped his chin as he considered the situation, a lucky turn that just fell in his lap. "How about... One demand... and we settle the Izuku issue? You win, I'll leave her alone. I win... You butt out. No matter what happens. Permanently. I win and I could empty my balls down your throat right before I take Izuku on a date and you can't say a word about it." She stopped her set to stare at him with a hanging jaw. "So? How confident are you today, Katsumi?"
She started her exercises again. Guileless people like Katsumi were so much fun! She probably didn't even realise even if she won that her little plan would backfire. Izuku would realise Saiki was avoiding her, she would try to figure out why, all he had to do was drop a hint in Katsumi's direction and that would be it. Izuku wouldn't give a damn what Katsumi would have to say about him after that, after so deliberately trying to drive a wedge between them.
"You agree then?" Saiki asked, doing his own stretches, not that it was quite as required for him but there was no harm in a little extra prep work. Katsumi was clearly in this fight to win it, unlike last time.
"Fine. Deku, plus one demand. You ready?"
"Sure–"
BA-BANG!
Saiki was put immediately on the back foot as Katsumi literally exploded at him, the blast propelling her at speeds much greater than he'd previously seen from her. Not only that, she was fighting smarter, refusing to let him dodge and weave out of the way of potential damage. Instead she worked to box him in, forcing him to dodge one way only to catch him with another blast in his path. Even as he tried to get space she propelled herself with another blast right back into his face with an eager grin.
He didn't have the time he had in their previous fight, the chance to pontificate in his own head and analyse her, but in the flash of seeing that smile, he couldn't help but feel it wasn't menacing like it was before. It was almost like she was enjoying herself.
"DIE!"
Well... She was still Bakugo. But still.
As the blast caught him in the face making him flinch back, he realised he couldn't play defensive here. It did him no favours. He was just letting her build up a head of steam. Her explosions didn't do as much to him as they would most other people but they still did damage. He got caught off guard, he had to leverage his strengths! Instead of continuing to avoid, he rushed her, attempted to force her on the defensive by rushing through her explosions.
Attempted. Katsumi was waiting for it. She grabbed his arm as it reached for her, used his own momentum against him to throw him and launch him with another blast. Strong and durable he might have been but he couldn't leverage that in mid-air. He sailed back-first into a tree– "Oof!" with enough force that even he felt it.
Meanwhile, Katsumi blasted herself into the air with an explosion powered jump, followed by a spiral of blasts that forced her body into a spin. "Howitzer..." she growled, her spiralling blasts whipping up a storm of wind before she drove herself toward the momentarily helpless Saiki, "IMPACT!" Her palm was only inches away from his body as she released all the built up explosive force in one giant blast! One she hopes was enough to break through his protection.
It was certainly enough to break through the tree. And the one behind it. Saiki tumbled helplessly as he was blown away, rolling to a stop in the dirt, his body smoking.
"Hah... Hah... Hahhh..." Bakugo panted with a wicked grin on her face. "How's that ya tough bastard?! Did your stupid resistance hold up against that?!"
Saiki coughed as he pushed himself off the ground. She was giving him time to collect himself so he would happily take it. Her mistake. He cautiously got his feet under him and rose, rolling out his shoulders and patting himself down. His hair tie was gone so his cobalt hair now hung free, his clothes mostly tatters, thankfully his underwear held up somehow.
Oh yeah. And he hurt. All over. That was one hell of a blast!
Not that he could let her know that.
"Well, I definitely felt that one," he admitted with a smile. "Can you do it again?" Because he really hoped she couldn't. He genuinely wasn't sure if he could take another of those.
"Bastard..." she growled, not answering one way or another. Saiki didn't want to take the chance that the girl with the explosive temper suddenly learned to be sneaky so he stayed cautious, letting her take the lead in their little dance again.
To his relief her stamina seemed to be flagging. The tank was clearly not empty but it seemed to be about where it was when their last fight started. Even if she managed to injure him this time, it wasn't enough to change the result if that was the case. He was well practiced at ignoring pain.
Minutes later, Katsumi was left panting. She wasn't injured like she was last time, though she might simply have been hiding it better. "Do you concede?" Saiki asked, the burns and abrasions slowly but visibly healing as time passed. He wouldn't be fully healthy again for hours yet but it was still intimidating to see the damage done to him go away, all while Katsumi had failed to do anything close to that since.
"... Fine." It wasn't growling, it wasn't angry, just an acknowledgement. Saiki found himself struggling to figure out where her head was at in that moment. Maybe she was a little more interesting than a ball of rage inside an eminently fuckable girl.
"Don't worry, Katsumi," he reassured her. "Even though I'm going to steal your girlfriend's heart–"
"What the–! That shitty Deku is not–!"
"–I fully intend to steal yours as well," he finished with the smirk she hated.
"Whatever," she grumbled, unbuttoning her jacket, "We doing this or what?"
Saiki had to fight to hold in his laughter, oh she might actually have been a little eager! "Keep your shirt on!" Literally. "That super move you used is probably gonna bring people out here. Not to mention, well, you actually did a number on me."
Somehow Katsumi didn't take his admission of her strength well. "What, so we can fuck when I'm injured but not when you are?"
"I won both times. So yes. Besides, I haven't even said what my demand is yet."
"It doesn't take a mind-reading quirk, creeper."
"Actually, I think I'll give you a choice this time," let her choose her own debasement, "Option one. You suck me off until I'm satisfied, put those pretty lips to good use." He raised a hand before she could yell at him. "Option two. You take my dick in your ass. I've never done that before, it's a nice new experience for us to share!" Juri the fucking prude. "Option three... You're mine for an hour." Like a whore.
"Yours?" she asked with suspicion.
"That's right. I can do whatever I want with you within that hour."
"Like those other options?" she asked in a flat tone, seeing the loophole like it was marked with hazard lights.
"Yup!" he admitted cheerfully. "Whatever I want. Of course, if you choose one of the other options... Well, I'm sure you'll make the decision you're most comfortable with. I'll message you my address. Come by tomorrow with your answer."
-(-)-
Saiki grinned when he saw Katsumi standing on his doorstep, hands in her pockets and for once not glaring at him. Finally it seemed her strong front had taken a little bit of damage! "Hey Katsumi. How's it going?" he asked, not able to keep the smug out of his voice if he tried.
He didn't try.
"Bastard." There was little heat in it, and she still wouldn't look at him.
"Well come on in," he gestured her inside, standing aside to let her pass.
She shuffled her way inside, not giving the traditional phrase when entering as a guest in someone's home. Saiki watched her look around with none of the bravado he had become used to from her. Smiling, he shut the door and locked it with a click.
"Shitty place," she commented, not at all wrong in her assessment so he didn't begrudge her for it.
"Well, it's what I get by with from the little money I get from my folks and my job," Saiki shrugged. "Not much room for luxuries when I have to pay UA tuition."
"Am I supposed to feel sorry for you?" she bit out.
… Saiki's initial intention was to just keep the small talk going, to let her dwell in her discomfort a little longer but the conversation had taken a turn he wasn't comfortable with. "No. I am not and have never been a charity case. I worked hard to get where I am."
Katsumi glanced at him, the first time she had looked at him today. Her expression was impossible to read. "Can we just get this over with?"
"Sure," he acquiesced, no longer in the mood for that game. He moved close to her and put his hands on her shoulders, peeling off her jacket. "So? What did you land on?"
"... Option two," she mumbled.
Ohhhh, fun! He knew she wouldn't tell him so he wondered to himself why she landed on that option. She probably tossed option three out as soon as she saw the loophole, considering it a trap option. But why not option one? Maybe she was more affected by that crack he made while fucking her. The first experience for her lips being a dick passing between them. She did seem pretty determined not to let him kiss her...
Still... Option three wasn't the only trap option. "I'm sorry, which one was that again?" he asked, voice quiet and teasing.
"You know full well what it was, you bastard!"
"Do I?" he asked, kissing lightly at her neck and making her shudder, "I really just threw them out off the top of my head. I don't remember what order they were in."
The ash-haired girl wasn't stupid. She knew he knew full well. But she also knew he wasn't going to get it over with until she said it out loud. "... My ass."
"I'm sorry?"
"It was my ass."
"What about it?"
Her hands sparked and smoked, pops of tiny explosions punctuating the silence.
"I want you to say it, Katsumi. I want you to admit what you want me to do." That was the trap. She had been given the option of leaving everything to him. Letting him do as he liked. By not choosing that option, she had made herself an active participant. She had asked him for this and he would make sure she would know it. "What do you want, Katsumi?"
"... I... Want you to fuck my ass."
"Louder."
She swallowed, feeling some of her dignity crumble and fall away. "I want you to fuck my ass!"
And there it was. "Good girl. Strip."
She was already in far too deep to complain, stripping her shirt off with only a little reluctance. Saiki's hands and lips started to wander downwards to the newly exposed flesh, his fingers taking a momentary detour to unlatch her bra. No sports bra today, just a plain grey number. Interesting. Her shoulders shrugged out of the straps and she let the undergarment drop to his apartment floor.
Hands continued to wander as Saiki sucked at her neck, only stopping to whisper "Keep going" as he stroked his fingers over her abs. Her own fingers fumbled with the fasten on her pants, snapping them open and letting them fall. She felt dirty being played with like this, being so submissive like this. But... She wasn't sure she'd consider it to be in a bad way?
"Get on the bed," he ordered and she complied once again. Confused when he didn't immediately join her, tearing off her grey panties like she expected him to. Instead he went to his bedside table and fetched a little bottle from inside the drawer. "You'll be glad I have this."
Oh. That was what it was.
She watched him come around to the foot of the bed. "Up, on your knees," he ordered and so she posed, ass raised in the air for him to peel down her conspicuously wet panties.
"Good girl," he told her again, sliding his palms appreciatively over her firm rear. It was no secret to him at this point how much Katsumi must work out and her perfectly firm and round ass had clearly reaped the benefits. He wanted to bite it…
"The fuck?!" she yelped as she felt his teeth nipping at her backside.
"Sorry, couldn't help myself," he admitted as he uncapped the bottle of lube and dribbled it into Katsumi's exposed crack, sliding his fingers over her little button and sloooowly–
"Nnnnh!" Katsumi groaned, face pressed into the comforter.
Pressing his fingers in, working the lubricating fluid into her tight hole, getting her nice and ready for the much bigger intrusion to come. Of course, he couldn't neglect her enjoyment either. He said he wanted to capture her heart and he meant it. A good step towards that was not being an entirely selfish lover. So even as he got her backdoor ready for its grand opening, he took the time to give her pussy some attention too. Attention that it clearly craved considering how wet it was. The fingers of his other hand just sank inside, the warm, wet flesh sucking on them as they began searching out the good spots to make her quiver and moan.
"Are you ready, Katsumi?" He might have asked the question but it didn't really matter, this was happening now.
She didn't respond. An eye peeked out, looking back at him before she hid her face in his blankets once again, bracing for what's to come. This was it. This was where her confidence got her. She had told herself that if she fought him seriously she would win. Now here she was, face down ass up waiting for him to violate her asshole.
As Saiki unbuckled his own pants and fished out his cock, he considered demanding she beg for it again but he suspected there was no need anymore. Instead, he slathered his meat with a bit more lube and slowly pressed the head into her backdoor, fingers rubbing circles into her pussy at the same time.
"Hnn, nn! Hnn!" Her grunts were muffled as the head finally popped inside. And so began the slow, careful process reshaping the hole to fit him. Little shallow thrusts inside to pry open her asshole inch by inch as he worked himself towards bottoming out inside her. All the while, Katsumi groaned and... "Breathe, Katsumi," he reminded her.
She took a gasp of air.
"Good girl, almost there," he cooed to her, two fingers delving into her feminine folds to give her something else to focus on. It was certainly a different experience to what he was used to. A bit more prep work, and it felt different. There was heat, and it was so much tighter than anything else he had experienced, but he missed the wetness, the suction. He was certainly enjoying the new sensations but he had to admit, what really brought it up to par with the other options was the dominance he was feeling. Katsumi submitted herself to this, she got nothing out of it, she was submitting her body to pain for his pleasure and there was a real rush, a thrill from that knowledge.
"I'm going to start for real now," he warned. And for the first time he pulled back and made his first real thrust into Katsumi's ass.
"Kah!" Katsumi gasped as her bowels were forcefully reshaped by Saiki's thrusting cock, jabbing her insides with his meat. All the while his fingers still tormented her pussy, alternating between rubbing and thrusting inside her, trying to bring her pleasure around the pain. Even as he planted his cock as deep as it could go his fingers seem to straighten, then, "AHHHHHH!" she screamed into the bedding as his fingers thrust at speeds she couldn't replicate, his thumb slapping her clit each time! Where did that come from?! It was too intense! It was–! "Ah-AHHHHH!" she squealed again as fluids spray out of her over the jackhammering fingers!
Meanwhile, Saiki figuratively patted himself on the back for a job well done. She'd be riding that one out for a good while, plenty of time for him to finish. Now comfortable with simply seeking his own satisfaction he continued thrusting away into her bowels, pressing down on her back to push her into the bedding (not that the dominant gesture was needed but it was the principle of the thing). Gods, he loved the shape of her ass too!
… Should he?
… Yes he should. Raising a hand, he brought it down on her right ass cheek with a loud slap!
"Ah!"
Slap!
"Stuhp!"
Slap! "It's coming, Katsumi," Saiki warned as he continues to smack her ass over and over, her cheeks now a burning red. "I'm gonna fill up another one of your holes!"
"Nn-hnnnn!"
"Take it, slut!" he demanded as he bottomed out one last time, once again spilling his entire load inside her. As his release finally ebbed, he pulled out slowly, enjoying the sight of his handywork when the head popped out, revealing her twitching, gaping hole, cum already leaking from it and dripping over her soaked pussy lips.
"Hahhhh," he sighed, satisfied as he put himself away. "You can borrow my shower if you like, get yourself cleaned up." She didn't respond right away, instead taking a few minutes to collect herself before taking his offer.
Katsumi leaned heavily against the shower wall as she let the warm water soothe the stinging from her cheeks, the ache of her abused and filled hole. Rivulets of Saiki's cum dribbled out to be washed away by the water. Another loss, another thing taken from her.
No. Two things. Deku would be on her own now. Katsumi might have hated the bitch for oh so many reasons all jumbled up and knotted together to make her angry from even looking at her. But… Katsumi wanted to be a hero. And a hero protected people. Despite the loathing, Deku was still a person and clearly had no idea what she was getting into.
Not like Katsumi. Who knew full well and yet came back for more. What was she even doing? That first loss hurt, her first time being like that hurt, but she could have moved past it. But Deku-!
… No. No, she was hiding behind that. Deku might have been the catalyst, the final thing to push her to act. But she wasn't the real reason.
On some level… She liked it. Not the debasement, not having to play Saiki's submissive little fuckpet, fuck no! But… The fighting, chasing a victory with something on the line! It was intoxicating! As much as she worried when Saiki changed the terms of their wager, she also felt a little thrill at the possibilities! If she lost, sure, that would hurt. And it did, her asshole spasmed to suddenly to remind her of that, making her wince. Though that thing he did with his fingers… But then again, if she had won! Deku, whatever, but also another demand! What would she have done? What would she have demanded of him? Probably force him to eat her pussy until she was satisfied! That would show him! Get him on his knees to worship her cunt like he should! Cum all over his face, smearing it with her juices!
She blinked as she found her fingers had wandered into her folds as she panted in desire for the picture her mind has conjured. But no, not here. As much as she wanted more, as much as she looked forward to the next challenge, with a new technique that would wipe that fucking smile off his face… She couldn't let him know. She would bide her time. She would prepare. And when the time came, she would make him submit to her!
Meanwhile, Saiki noticed she didn't collect her clothes and decided to take a prize for himself, stowing her damp panties for safe keeping. When she came out of the bathroom he pleaded ignorance when she asked for them but they both knew what happened to them.
Fully dressed and very much wanting to leave and... Think. Katsumi allowed herself to be shown out.
"I look forward to next time," Saiki assured her with a smirk.
"... Yeah."
The aspiring hero of dubious morality watched the girl go, trying to figure out that last exchange. No bravado, no declaration of victory for next time? No anger?
… Did he break her? No, of course not. She wouldn't be half as interesting to him as she was if she were to break that easily.
Well, that was a question for another day. Picking up his phone, he made a call. "Hey, Izuku, how are you doing?"
"Oh, Saiki! I was just thinking ab– I–I mean... Hi!"
"Hi. So are you doing better? Your injuries okay?"
"Oh, yeah, Recovery Girl did a great job like always!"
"Uh huh?" Saiki agreed, his attention lapsing as he watched the door of his apartment close just a little too slow to be natural. "So how did you spend your extra day off?"
"Well the way Recovery Girl's quirk works makes you tired after she uses it on you so I didn't get much done..."
"Even so, I'd like to hear about it," he insisted as the door latch clicked into place. Katsumi's delayed exit conveying just a little more of her own feelings than she perhaps intended.
And soon? He would have Izuku screaming his name. He just had to be patient.
