The smack of a palm against soft skin sounded through Saiki's apartment in a steady rhythm. Every crack followed by a sharp intake of breath, Saiki, or rather the newly dubbed hero-in-training Evo had one of his classmates over his knee. Katsumi's skirt pulled up over her backside, her spats and slim panties pulled down to give unrestricted access to her now reddened backside. The explosive girl hung her head, both from humiliation and for the sake of hiding her reaction. She would rather die than give him the satisfaction of seeing her flushed, embarrassed and worst of all aroused face. To say nothing of letting any sound pass her lips.
Not that Saiki was willing to let her get away with that. "You know, I forget. How many did we agree you earned for messing up today?" The blonde's teeth were clenched. She stayed obstinately silent. "Hm. Ah, damn. I think I lost count. Guess I'll have to start over, unless you remember, Katsumi?"
"We didn't agree, creeper!" she bit out, hiding her arousal beneath anger, "You just said fifty and told me to bend over! And you were on forty-thr-hee!" His hand came down on her ass again as she spoke, turning her words into a humiliating whine.
He snapped his fingers as if reminded. "That was it. Though," another crack to her backside, though this time his hand didn't come away. Instead he slid a finger between her cheeks, down to her moist slit. "What was that you called me just now?"
"S–" For a moment, she almost lied. But in the end, her pride wouldn't let her. "Creeper." Not like lying would have gotten her off the hook anyway.
Saiki hummed to himself, slipping two fingers inside her, diving and pressing into the soft flesh of her womanhood. He put Katsumi's well-earned spankings on hold for the moment, long enough to finger her to a reluctant orgasm. "You feel that, Katsumi?" he asked as her legs kicked against his, "That's what honesty feels like. Not that it'll get you out of the rest of your punishment for getting it wrong again."
Six more strikes to her cherry-red cheeks and she sighed in relief that it's over. The stinging soreness wasn't a patch on the shame from how much she enjoyed it. To think she had thought Saiki's latest demand had been mild. She hadn't considered the implications that he wanted her to only refer to him by name, and what would happen if she chose not to. Worse, her pride demanded she defy that order to spite him. And so she knew she would just end up in a situation like this one again and again.
Unless... She just did what he–
Her internal thoughts came out with something similar to a derisive snort. Yeah. Katsumi Bakugo giving in and submitting. That was totally a thing that was gonna happen.
Saiki pulled open a drawer on the nightstand next to her, though Katsumi couldn't see what he pullsed out, facing the opposite direction. She heard the sound of skin against skin before she felt a cool, soothing sensation as her blue-haired classmate and occasional lover (though she would kill him before she would ever call him that) rubbed what must be some sort of ointment on her abused butt. "Why do you even have that?" she asked irritably, looking away again to hide her blush at being treated tenderly.
"You know how my quirk works," he answered, "I have enough stuff like this to fill like, ten first aid kits. I go through so many bandages, thread, antiseptic and painkillers the convenience store clerk probably thinks I'm some kind of back-alley doctor or something." She heard the click of something, probably the cap for the ointment. "Feel better?"
She continued to look away, disgruntled, demanding her body to follow her instructions and send blood somewhere other than her face. "Yeah, whatever, I guess."
"Good!" he cheered, "Now for your next punishment, on your knees please."
She slid off of his lap, considered pulling up her panties but decided not to just yet. She would like the chance to clean up first, and also he might want them down still for whatever bullshit he wanted her to do next.
That was her story and she intended to stick to it.
She saw Saiki's fingers unbuttoning his pants and she looked him dead in the eyes. "No." She wouldn't do that. That went way beyond what she was willing to tolerate for a 'punishment'.
"Relax, I'm sure I'll get those pretty lips wrapped around it eventually," he smirked down at her as he pulled out his erection. "For now though, just your lovely tits will do fine."
"My–?" she asked, confused. "Why? They aren't even that big." She quietly thanked whatever genetic miracle responsible for her not inheriting her mom's. No way in hell she wanted to have cow tits like fucking Deku.
"They're big enough," he answered as if speaking from experience. "Come on, sooner you get me off, the sooner you can get gone," he reminded her.
She scoffed as she opened her shirt, reached back to unclasp her bra and let both garments fall off her shoulders. "Whatever. Fucking c– Saiki," she quickly amended. Screw him and what he wanted her to call him, but at the same time flouting his demands twice was probably enough for one day. Gods forbid she kept doing it long enough she wouldn't get to leave today. She was sure if she gave him the opportunity he'd force her to literally sleep with him. Would probably demand they cuddle just for the extra humiliation. Eugh.
No it wouldn't feel nice! Shut the hell up, stupid voice in her head!
Her movements were uncertain but rigorous as she moved forward, pushing her breasts inward with both hands to wrap around his cock. It took a couple of minutes but eventually her movements became more confident, more sure. Basically like a handjob but with her tits in the way.
"There you go," he praised in a sigh, "See? Just the right size, and so soft."
"You don't have to fucking talk while I do this," she groused, sliding up and down over his shaft, grimacing as she saw the head poke out of her cleavage.
"Don't have to, but I want to," he shrugged as he lays back. While his disinterest in her was irritating, it also gave her more room to work, and hopefully have this over quicker. "So, you picked out what agency you'll be interning with yet?"
"The hell would I tell you for? It's none of your damn business!"
He gave a pleased little hum, a sign he was enjoying himself, a sound that egged her on, pushed her to experiment a little, find out what he liked. To make it end faster of course.
"Just making conversation. You wanna know where Izuku is going?" he asked teasingly.
"Fucking Deku," she grumbled under her breath. "You gonna cum yet or what?!"
Infuriatingly for her, he took that as a yes. "Apparently one of All Might's old mentors offered her a spot. She's hoping the guy will be able to help her master her quirk since it's so similar to All Might's."
"She's nothing like All Might!" Katsumi snapped, her movements increasing with her fury, "She's a worthless Deku! It should be her fat cow tits here, not mine!"
"Gah, I love it when you get all hot and bothered about her," the bastard groaned, "Your whole hyper-tsun thing is so fucking cute!"
"Shut up!" she barked, bouncing her tits with vigour, "Just fucking cum already so I can go!"
"You know what would be great? Izuku joining you right now," he spoke dreamily, getting lost in his imagination. "My cock trapped between your tits as you fuck her mouth with your tongue. Maybe Momo too, underneath, tonguing my balls."
"If you're gonna fantasize do it about those two. Leave me the fuck out of it."
"Not a chance!" he laughed. "That anger of yours? That passion? It's the hottest thing in the world to me right now. I want to fuck it out of you. Or into you. Or both." She could hear his breathing get heavier. He was getting close. Fucking finally. A small spurt of cum squirted out of his cockhead. Then a much larger spray that splashed onto her face.
"I want to fuck you and turn you into my dirty little slut."
Two more spurts, one over her right eye which she thankfully closed in time. The other over her lips. Which she did not close in time. It was salty. Not unpleasant.
"Think of finger-fucking you as a kindness."
More splatters over and between her tits as his climax ebbed.
"Willing to get on your knees and service me just because I said so."
"Enough of your shitty daydreams," she groused, sitting back, still with her panties around her ankles, face and chest given a fresh coating of cum. "Can I fucking go now?"
He looked down his body to smirk at her, still kneeling before him. "Sure. Do as you like. Just remember the rules next time."
"Whatever."

Jonosu. It was a little afield of Musutafu. No especially convenient travel options for a daily commute. Thankfully for Saiki, his choice for internship had okayed him sleeping and living at their office for the duration of his time with them.
It wasn't much of an inconvenience at all as far as he was concerned, compared to the opportunity presented. He had quite a number of high-profile heroes on his list. Not all. Notably Endeavour didn't show interest. After a little asking around he had discovered only Todoroki had gotten an invite from the number two hero. Nepotism. Well, Todoroki could have all the shortcuts to greatness he wanted. Saiki knew he'd surpass the two-tone prodigy anyway.
There were only two factors Saiki took into consideration when choosing with whom he would be interning. First, was prestige. It would be a waste of his victory at the sports festival if he ended up going with some no-name hero at the end of it. Todoroki had a fast track, Izuku had All Might in her corner for whatever reason. He needed to milk every opportunity to its utmost. Second, the potential for him to grow stronger, more capable from the experience. Sure, internship was just to give students a feel for what day-to-day heroing is like, but if he could learn and grow as a hero from the experience, that would be something worth doing.
In the end, he found someone who was perfect. Well, not quite perfect. There were more prestigious options. He could have gone with Best Jeanist or Crust. They were both better rated heroes. But Saiki knew what an internship with them would be like. Best Jeanist would be all about putting out the right image of a hero. And Crust... Well, Crust wouldn't be terrible, but not great for what Saiki felt he needed to learn either.
No, his final choice was exactly what he needed. A popular and strong hero, with exactly the attitude he wanted to embody. And even better, she fulfilled a third criteria that Saiki wasn't fully weighing as part of his choice, but was certainly a nice bonus.
He frowned. To look at her workplace, he wouldn't think of it as the place a top rated hero lived and worked. It was a nice place, completely detached from other buildings. A luxury in a crowded part of Tokyo. But it was also not exactly grandiose. He knew his boss for the week wasn't one for running a full-on agency with sidekicks, but if he didn't know any better he would think the place was just the home of a mildly affluent family. Still, it was the right address. He hit the doorbell. The attached intercom crackled to life soon after. "Yeah?"
"Hi, I'm Saiki Saisei, your intern for the week."
"Oh, right! That's today! Hold on, I'll be right there."
Saiki waited patiently, suitcase in his left hand, costume case in his right hanging over his shoulder. He listened, waiting for the sound of footsteps on the other side of the door but heard nothing. At least no footsteps, he did hear the scraping of something opening, then a loud thud from above him. Out of the corner of his eye he saw a growing shadow, then–
"LUNA FALL!"
"Guhuagh!" Saiki blurted out in pain as he felt a powerful strike land on his left shoulder, enough to smash his whole body into the concrete slabs of the front path. Both cases flew from his hands, forgotten in the pain of a surprise attack that laid him out in one blow.
Shakily, his head came up, getting his first in-person look at his mentor for the week. The very first thing he saw was what, to him, was her most defining feature. Her incredibly powerful legs, dark and muscular thighs, then up to her purple and white leotard, a gold crescent embossed over her bust. Then up to her sharply grinning face and prominent rabbit ears. Rumi Usagiyama. Mirko. The number eight hero in Japan. "Man, I knew you wouldn't die from that but you can still move? I'll give you some credit, you sure toughened yourself up, huh? Gotta work on your situational awareness though."
"Wh-y?" he struggled to say as he raised himself to hands and knees.
"Well here's the way I figure things," Mirko continued to grin at him, putting a foot on his back, impatiently tapping it. Each tap felt like someone punching him in the spine. "You're here to learn how to be a better hero, or, how to be a hero at all. You won the sports festival so you had your pick of top hero agencies, but you chose me. I don't have a big, fancy agency. I don't have sidekicks. I can show you the basics of being a hero but that'd take like, a day." She grinned wider, wilder, when she felt him push against her foot to rise into a kneeling position. "So that means you're here for the kind of training that matters more than any of that boring admin and patrol crap." She turned, and despite the hit he just took he couldn't look anywhere but at how that leotard accentuated her beautiful ass, the hypnotic sway as she walked back into her house. "Come on then. Grab your shit. It's about time we get started."
"Right," he grunted, rising to his feet. He quickly grabbed his costume case, then his suitcase before laboriously following his mentor into her house. One good hit and he felt as worn out as he did by the end of the festival. Just from that moment, he knew he chose the right mentor.
Mirko led him first to the room he'd be staying in for the week. A fairly ordinary guest room with a futon where he deposited his things. "First things first. Get changed into your costume. You've got one minute."
"A minute?" he echoed. His costume wasn't the most complicated but still!
"You wanna be a hero? You hesitate? You waste time? People get hurt. Fifty-five seconds." Her foot started tapping again, her toes thumping against the floor.
Eighty seconds later he emerged from his room fully suited up. "Work on it," she told him, ordered him. "This way is the kitchen. Don't expect me to cook for you and you clean up after yourself. That's all you'll need up here. Follow me and we'll get started on the reason you're here." She led him around the side of the kitchen to a staircase leading down.
"A basement?" he asked, confused and sceptical as he followed her down. "In Japan?" That scepticism lasted until he followed her down into it and found not only did the underground space cover a wider square footage than the building above, it was built incredibly sturdy despite the high ceiling.
"Welcome to the Bun-ker," she told him with arms spread wide to show off the space. "My personal training space!"
It was certainly something. Saiki couldn't help but be impressed. She must have spent most of her money first creating this underground space, and then on turning it into her own fitness palace. Gym equipment of every type. Not just standard fare equipment either. The same type of high-spec equipment UA had in their own facilities graded for quirk use. And by the look of all the broken and discarded ones, Mirko went through heavy bags like tissue paper.
"Alright!" the Rabbit Hero exclaimed, hopping into the middle of the space. An enormous clear area. "Get over here." Cautiously, Saiki walked towards her. But as he stepped over a line he thought was to demarcate the equipment from what looked like a space for practicing kata or sparring, Mirko spoke again. "System. Ring."
Suddenly, right behind him, a wall rose from the floor cutting the circular space off from the rest of the Bun-ker.
"Okay. Let's get started. Come at me."
Saiki blinked. "You serious?"
She gave him a flat stare, one filled with impatience. "I'm gonna say it again. If you don't do it, you'll regret it. Come at me."
Well she was literally asking for it, he thought to himself. But that one hit he took was enough to leave him cautious and he wasn't anywhere close to recovered yet. He moved forward, closes, but didn't rush in.
This it seemed, was the wrong response. The moment his approach slowed, she launched herself forward, flipped in the air and kicked him in the side with a twirl. She didn't let up from there either. She followed his trajectory as he sailed toward the wall, cartwheeled and dropped one leg onto his back, driving him into the floor again.
"And there it is," she said as she stood over him. This time as she planted her foot on his back she had no intention of letting him push himself up. He would stay right where he was and listen.
"Do you know why I invited you to intern for me?" she asked. "You know as well as I do I don't do teams. I don't do sidekicks. So why would I want an intern who'll slow me down?" He at least had the good sense to realise that question was rhetorical. "It's because that sports festival? Watching you win all your matches? It pissed me the hell off." Her foot came up, tucked under his torso and flipped him over to reveal his pained grimace as he clutched his side.
"As far as I'm concerned, you should've lost almost all of your fights," she told him as she squatted next to him. "That hardening kid? He didn't have a chance. Not enough fight training. But everyone else? The best you did was in the final. That one you almost didn't embarrass yourself except how you won because your opponent messed up, instead of because you were better. But the other two? Against that bird shadow kid, that was the most embarrassing display I've ever seen. For both of you. You just slam into each other and hope you win? It was pathetic. But it was nothing compared to that bomb girl. Now she was something! When she took her shot at you without even waiting for the ref I almost wanted to adopt her, let alone let her intern with me. But she doesn't have anything to learn from me. She has the instinct of someone fighting to win. You? Every single time you were fighting to not lose. That's not even close to the same thing."
"So. Whether you like it or not, that's what I'm going to teach you. Think on your own time. In the middle of a fight it's time to let instinct and training do the thinking. And I'm going to train you to win."
Saiki coughed, took a wheezing breath that turned into a choking laugh. "Whhhh, why do you think I wanted to intern with you?"
The sharp grin spread across her face once again. "Well alright then. We've got a lot of work to do."
