The train was full and Katsuki hated his life. Bodies were pressed against him and he could smell the cologne of the man in front of him. It was revolting. He could not hold onto anything except his own bag and he could not get a solid enough of a stance, but the people around him prevented him from falling flat on his face every time the train jostled.

It still made his skin crawl.

Something or someone brushed against his back and Katsuki tensed, trying to turn his head to see who it was. It was a girl around his age and she was smiling apologetically. Katsuki scowled at her, which made her frown.

He didn’t have the energy to handle the emotions of some extras in the train. Spending the weekend with his parents was exhausting enough, he just wanted to get back to his dorm room and relax.

She would just have to deal.

He scowled harder at her, which made her face redden. Katsuki couldn’t gather enough fucks to even start to figure out what emotion was responsible. Embarrassment? Anger? Who cares? Not him!

He wanted to get between his All Might sheets and sleep until his alarm clock rang and he would have to start doing his morning exercises. Eight hours of glorious uninterrupted sleep, unless Todoroki had found a funny picture and felt the need to share it at 2 am. Again.

He had threatened to break up with him if Todoroki did that again. It had been far more threatening three times prior.

Urgh. Two stops. Then home. Something slammed against his back and in the heartbeat between the hit and him turning around to glare, everything froze. He couldn’t move his hands, open his mouth or even blink. For a moment he just stood there, unable to think beyond the sudden flashing terror. He could barely breathe.

The train stopped and some people left with more people getting in, and it wasn’t until the train started to move that the feeling released and Katsuki took a huge gulp of air. He gasped for breath, and the man standing next to him gave him a side-eye and tried to inch away with barely any luck. Katsuki turned around, but he couldn’t see the girl beyond all the bodies. She might have left the train at the stop, if she was smart.

Katsuki shuddered and rolled his shoulder, the tension making it stiff. Fucking shit.

Getting off at his station and walking to the UA was tense, and Katsuki kept glancing around, waiting for an attack. But nothing happened. Even entering the building was peaceful with only Shouji in the kitchen and waving his hand in a small hi. Katsuki nodded at him and went to his room.

Bundling up in his bed was far less satisfying than he had expected and it took awhile for him to fall asleep.

The next morning, he woke up feeling sore all over, and did the morning stretches more carefully than usual. Katsuki rolled his shoulders, dressed up in his running outfit and took off. No one else was awake yet when he left and he could only see one familiar second year student in the running track. They gave each other a stiff nod as a greeting and then proceeded to ignore each other while running their laps.

It was glorious. His muscles started to loosen up, he could feel the energy from a good run enter his system, and couldn’t stop the small smirk from appearing when he stopped running. The other student had left a few laps before and Katsuki had gotten to spend some time on his own, concentrating only on his breathing and the sensation of his shoes hitting the track. It had felt amazing.

Classes would start soon so he would need to hurry. He took a quick shower, blow dried his hair, and dressed up in his school uniform. Then he walked briskly to the classroom.

Todoroki was standing outside the classroom, clearly waiting. When he saw Katsuki, the look on his face brightened. Katsuki blushed slightly and pushed his arm against Todoroki, who did the same thing. Something warm and gooey grew in Katsuki’s belly and he told it firmly to stop. Todoroki just smiled his airy smile, so Katsuki scowled at him and walked into the classroom.

The school day had felt longer than ever before and Katsuki had struggled to make notes. Concentrating was difficult. Every time he stretched, his joints had cracked so loudly that Katsuki was certain that everyone in the classroom had been able to hear it. Midnight had even given him a stare after a particularly loud one.

The physical training was even worse. So bad that even All Might was giving him concerned looks when Katsuki stretched for the nth time. It helped, but only for a moment. Katsuki ground his teeth in annoyance. 

There had also been another problem which hadn’t gone away yet. His hard as rock erection was drilling a hole into his underwear. Even if he had gotten so much shit over it, Katsuki was now very happy that he had insisted on getting pants at least two sizes larger than his own because he didn’t know if he could have hidden it otherwise. 

The moment All Might told them to stop and wash up, Katsuki let out a small relieved sigh and walked briskly towards the showers, ignoring the few questions directed towards him. He wanted that shower and he wanted it now. But his dick was still hard and showed no signs of softening.

Katsuki snarled, reluctantly took his clothes, and walked towards the housing. The walk with a raging hard-on was no more difficult than exercising with one, but it sure as hell wasn’t any less awkward. Katsuki tried to discreetly push it on the side, hiding it behind the folds of his clothes, but the slight touch to his dick through his underwear created such a strong wave of pleasure that he moaned out loud. Immediately Katsuki looked around, but there was no one there that could have heard him. The rush of heat on his face did make it clear that he was blushing, so Katsuki almost ran towards the dorms.

The sound of his dorm room door being slammed close had never sounded so good. Katsuki dropped his school bag and pushed his right hand immediately into his pants, almost coming the moment he touched his dick. It was more sensitive than before. Katsuki dropped onto his bed with enough force to bounce, but he couldn’t hold back. It took a firm hold and one pull to come harder than ever before. Light flashed before his eyes and Katsuki groaned loudly enough to have woken the dead.

For a moment he stilled, listening quietly, but he could hear nothing beyond some distant bird chirping. After a few heartbeats, he relaxed. Rest of the class must have been really slow on getting back.

Emboldened by the realization, Katsuki got up and pulled off his now come-stained pants and underwear to grab his dick again. It was still a bit hard, the orgasm having only been able to take the worst of the edge off. He laid back down more comfortably, putting his hand around his cock once more. Katsuki gave out a small moan and squeezed slightly, his dick rapidly hardening. He shuddered and began the familiar movements.

Four orgasms. Four orgasms and he was still hard . His dick was red and touching it was starting to become painful, but he couldn’t stop. He had tried, but the pain had become too much. 

Katsuki had thought of getting his dildo from the bottom of his drawer, but the thought of not being able to jerk off while getting it and preparing himself was too much to bear. A hot tear fell down his cheek and Katsuki bit his lip to keep his sob in.

He should have told someone. He had sensed that something wasn’t right, but he hadn’t told anyone. And now he was paying the price.

Then there was a knock. Three measured knocks, sounding the same, and on the same spot. It could be only one person. Now Katsuki let his sob out and coughed, trying to clear his voice, “What is it, Half-and-Half?” Todoroki could help. He would be able to take the pain away.

“It’s me.”

I fucking know you-!

“Get in!” Katsuki roared, but there was only silence and the door didn’t open. 

Katsuki opened his mouth to scream when Todoroki said, “I don’t have the key.”

Katsuki swallowed down his scream, but not his anger, and somehow managed to lift himself off the bed, his dick hard and angry-red. Taking the few steps towards the door were harder ( hah ) than he had ever taken, but he managed to barely take them. When Katsuki opened it, he stood behind the door so that no one (Kirishima or Shouji) could see him, and so that Todoroki could walk in immediately.

Then Todoroki just. Stood there. A vague frown started to grow on his face, but Katsuki was too furious to notice it. He snarled out, “Get the fuck in,” which finally made him move. The moment Todoroki was inside, Katsuki slammed the door closed and immediately regretted it. All of him was now visible, his cum and sweat stained body, hard and painful dick, and the shaking that Katsuki was trying very hard to ignore.

Todoroki’s frown deepened, “What happened to you?”

Katsuki snarled at him, but hesitated. It was hard to figure out what to say and what would give him what he wanted.

“I am just - just really horny.” 

Even Half-and-Half wouldn’t believe that. “You’re lying.” And he didn’t.

Katsuki stood up straighter, his back making a loud crack sound. Sex would help. He needed to have sex. How could he make Todoroki have sex with him…?

“Are you sick?”

“No!” Katsuki yelled the moment Todoroki’s question registered in his brain. This wasn’t an illness, just - just some sort of an annoying quirk, it would be over soon, what did he - 

“No,” he said more calmly. “Some asshole slammed into me on a train yesterday and I have been horny ever since.”

This didn’t seem to calm Todoroki at all. “Have you spoken to Recovery Girl or Aizawa-sensei?”

Katsuki squirmed, folding his arms before him. Being completely naked before Todoroki was awkward, but it was quickly becoming humiliating. “I’m going to when I’m not so-” The words were thick in his throat, but Katsuki forced them out, “not so hard.”

“Ah.” Todoroki’s eyes flitted downwards and he started to blush. He turned his head slightly and stared very intently at Katsuki’s computer chair.

Why the fuck was he embarrassed? He had seen Katsuki naked before. They had done a hell of a lot more naked before, far beyond standing and talking. Katsuki heroically ignored his own embarrassment to get annoyed at Todoroki’s own.

Well, in for a penny… “Wanna fuck?”

That reaction was glorious. Todoroki’s head immediately snapped towards him, his eyes widened, and his jaw dropped. Katsuki didn’t know why he was so surprised. He had said those exact same words to him five days ago!

Idiot . Katsuki ignored the fondness surrounding that thought. This was not a place to get mushy.

“Would that be-”

Katsuki knew exactly what he was gonna say. “It just made me horny, it didn’t cloud my mind!” Katsuki let out an annoyed huff. “I was already waiting to get back here to have sex during the weekend, it’s not like it was forced into my brain.”

“During the weekend…” Todoroki said, sounding contemplative. Katsuki could feel heat grow on his cheeks and tried very hard to force it back down.

“How romantic.” Now that bastard was smirking. Katsuki was gonna kill him. Instead, he grabbed Todoroki by the collar and pulled him close. His lips met Todoroki’s with a bit too much force, the kiss starting as more of a bruising press of lips rather than a real kiss. Even their teeth clacked together, but Katsuki was too horny to care.

The moment they pulled apart to breathe, Katsuki tugged at Todoroki’s shirt and luckily, the blockhead understood what he was trying to do, and pulled his jacket off while Katsuki loosened his tie. The moment it loosened enough, Katsuki pulled it off and threw it to the side, not looking where it landed. Todoroki let out a small chuckle, which Katsuki smothered by kissing him again.

A moment later, Katsuki wasn’t certain how Todoroki had lost his shirt and his belt, but he was pulling off his pants in such a rush that one of them got stuck on his leg. Todoroki had to balance on only one foot and jump up and down, looking like an idiot. Katsuki let him know it by calling him that while laughing hard enough to pull a muscle. The glare Todoroki gave him was beautiful, but Katsuki’s own hard-on demanded for help.

The moment Todoroki was as naked as him, his own dick still half-mast, Katsuki gave him a firm shove. The force of it made Todoroki take several steps backwards, his legs hitting the edge of the bed, making him sit down on it hard.

“Hey,” the furrow between Todoroki’s eyebrows was a small one, but Katsuki recognized the tone. Katsuki grunted and the furrow immediately disappeared. Katsuki tried to will his blush down, but the small twist of Todoroki’s lips told him that he was failing.

That fucker could read him far too well. Katsuki made a face at him and kneeled on the floor in front of him to pull his knees apart. Katsuki glared at Todoroki when he saw the small twist of a smile grow. Katsuki raised his arms, stretching to get rid of the stiffness and showing off his muscles. The dark look in Todoroki’s eyes made him grin, so he flexed a bit more than was necessary.

Katsuki reached towards Todoroki’s dick and squeezed it gently, making a small hiss of a breath escape from between Todoroki’s lips. The grin on Katsuki’s face grew wider until he opened his mouth and gave the head of Todoroki’s cock a small kitten lick. The musky taste was almost comforting in its familiarity. Todoroki sighed above him but Katsuki didn’t let it distract him; He was on a mission.

Katsuki opened his mouth wider to put the whole cockhead inside his mouth and sucked on it gently. Todoroki’s cock was now fully hard, its ridges familiar against his palm. He sucked on it harder and a taste of precum entered his mouth. Katsuki smiled around Todoroki’s dick and pulled off slightly to start licking on the outside of it in long strokes to get it as wet as he could while rubbing his palms against it.

Todoroki had always said that he liked how soft his hands were.

Todoroki’s thighs were twitching and he kept his hands forcefully on the bed. The sight of it made the warm feeling in Katsuki’s chest grow.

He alway remembered that Katsuki hated having his head held down. Katsuki slowly took the dick deeper, the head of Todoroki’s cock hitting the back of his throat, and gave out a few messy slurps. Todoroki’s groan was a miniature symphony, the slow climb into a high pitched gasp making Katsuki almost choke in his mirth.

That’s quite enough , Katsuki thought, and carefully pulled off. He didn’t want Todoroki to finish too early. He had plans for his boyfriend.

Even Todoroki’s pout wasn’t enough for Katsuki to continue. He got up, put his hand against Todoroki’s chest and gave him a firm shove, making Todoroki fall down on the bed, narrowly missing hitting the wall with his head. The glare Todoroki gave him wouldn’t have scared a puppy, but Katsuki gave him points for trying.

“Lay down properly,” Katsuki said. Todoroki obeyed, settled down on the bed, and leaned against the pillow in a half-sitting position so they would both be more comfortable. And that Todoroki wouldn’t get a concussion again.

Recovery Girl had not believed their excuse for it and it had taken a long time to make her understand that it hadn’t happened because of fighting. She had laughed so long and hard that Katsuki had wanted to kick her through the window. Only Todoroki’s dazed and vaguely nauseous look had stopped him.

Though the condoms she had given them afterwards had come in handy.

Katsuki smirked at him and climbed on Todoroki’s lap. He stretched, the small pops coming from his shoulders and back ringing loudly between Todoroki’s near-silent gasps of breath. Katsuki rubbed his ass against his dick, which made Todoroki look like he was a hair away from burning the bed to ashes.

Hah. Showed him.

Todoroki visibly gathered some sort of brain power to say, “We need lube”.

Katsuki growled, his own dick twitching painfully and his skin tightening around him. “No we don’t.” Todoroki looked apprehensive and Katsuki grumbled, “we’ve done without it before.”

Todoroki looked contemplative, but nodded at the end. Katsuki smirked and reached for Todoroki’s dick, the touch of his hand making Todoroki go cross-eyed. He positioned himself above the cockhead and slowly lowered himself down.

A small hiss of a breath escaped his lips at the friction, but it wasn’t bad. It was really good. Much better than the last time they fucked without lube. So good that he couldn’t stop, just steadily lowered himself until his ass hit Todoroki’s hips. The familiar feeling of fullness was amazing and the moan he let out would have made pornstars blush. Katsuki immediately reddened at the slightly wobbly smirk Todoroki gave to him, and slapped his hand against Todoroki’s chest. Dickhead.

Katsuki leaned forward, put his hand on the wall to be more stable, and lifted himself up slightly, starting up a familiar rhythm. The brush of the cock against his walls felt good, excellent, and the painful pressure around and inside him finally eased, making everything more bearable.

Katsuki slammed himself down and Todoroki let out a small shriek, his eyes nearly rolling over. Katsuki would have laughed if he wasn’t too breathless for it. He was dripping sweat, the rivulets of it creating several paths down his back. Katsuki raised his eyes from Todoroki and noticed that he had slammed his hand directly on his All Might poster’s crotch. Any other time he would have removed it in fear of damaging it, but he couldn’t do it now. He was too close. The pain would come back if he stopped.

Todoroki put his hand against his back to pull him closer and sucked on Katsuki’s chest. Katsuki shuddered, the feeling of lips on his nipple made him almost falter. In retaliation, he squeezed around Todoroki’s cock and the ensuing moan against his chest felt like a victory.

Take that, Half-and-Half!

Todoroki took revenge by using his free hand to tweak Katsuki’s other nipple. Katsuki moaned and wondered feverishly why everything felt so much more sensitive than usual, yet his joints kept cracking?

Todoroki finally thrusted his hips forward and every thought disappeared from Katsuki’s head. That lazy bastard was finally starting to work for his living.

He was close. Everytime he fell down, Todoroki thrusted up, and he was so, so close and hot, but he couldn’t spark. That poster was a rare edition. The pain was finally gonna go away…

The moment it let go, everything went cold and dark.

For Kirishima, everything was normal. Sun was shining, he was doing homework, most of the class had gone to a mall, and Bakugou and Todoroki were having sex next door. The usual. He had put his noise-cancelling earphones on the moment he had gotten into his room, finding out that Bakugou was a screamer was quite enough information. He didn’t need to know anymore about their… activities.

Kirishima looked at the clock. It had been an hour. Maybe they had already finished? Sometimes, they would do it for hours. Better check anyway. Kirishima lifted one earphone carefully, preparing to put it down at the first hint of a moan or shriek.

He didn’t expect to hear Todoroki screaming for help. Kirishima rushed out of the room and grabbed Bakugou’s room’s door handle. It was locked. Todoroki screamed again, the sound of it spurring Kirishima into action. He hardened his hand, punched through the door, and used the hole to open the door from the inside.

The moment he saw them, Kirishima froze. They had been having sex. Bakugou was on top of Todoroki, the expression on his face lewder than Kirishima had ever thought Katsuki could look like. Todoroki’s… penis was still inside Bakugou, and Kirishima lifted his gaze immediately upwards the moment he realized it. And Katsuki...

Katsuki was still. Frozen. Grey. Grey like…

Stone.

Todoroki was crying. “Please get help,” he said, his voice broken from, what, screaming? How long had he been screaming for help, but no one had come?

Kirishima nodded, feeling small and scared and ran out to get Aizawa. Sensei would know what to do. He would have to.
