Midoriya had managed to get permission from the school to stay home that weekend, not wanting to risk another incident with Katsuki, yet when he returned the following Monday, Kirishima claimed to have taken part in zero sexual activities with the boy at all.

"He's just been super grumpy the whole time." Kirishima was saying as they sat at the dining table together at the end of a long day. "I mean, more than usual. He didn't talk to me at all, but stayed locked in his room."

Izuku hummed in thought as he listened. The two had held off discussing the Bakugou situation until the end of the day, and now they were finally alone. The rest of their class were all scattered around the dorm, most were probably in their rooms. Over the weekend, Eijirou had tasked himself with finding some information on the quirk so he would have something to give Midoriya when he came back to UA. But he had hardly seen Bakugou at all.

Midoriya pulled the lollipop he was sucking out of his mouth to speak clearly. "Maybe the quirk has worn off? It has been a week now. But we can't really make that decision until we see Kacchan. Did he talk to you today?"

Kirishima shook his head. "Barely spared me a glance. He's pissed at something, but I have no idea what." They said nothing for a while, until Kirishima sighed and hauled himself to his feet. "Well, I want a shower. I'll see you later."

Midoriya nodded and watched the boy walk away. As much as he wanted to, Izuku couldn't dwell on the situation too long. So he turned back to his math textbook to continue reviewing that day's work. He sat there a while, pouring over the problems and working to solve them in the fastest time he could.

The lollipop was held between forefinger and thumb as he worked, and his tongue poked out and swirled around the sweet a moment before pushing it back between his lips. He didn't put it all the way in his mouth however, but held it resting on his lips as he sucked lightly on the end.

Katsuki grew hot watching the innocent scene. He had been standing in the doorway since Kirishima had walked away, glaring at the boy sitting at the table. His body ached all over, not from the training, but from the sensation of every dust particle in close proximity brushing against his skin. His throat burned from the hot, humid air he had been breathing outside, then stung as he moved into the air conditioned dorm building. He knew his afternoon had been ruined when he saw Midoriya sitting at that table.

Or perhaps not.

Katsuki walked over with an air of authority then stopped just inches away from the other. Izuku looked up warily but neither said anything. Not until Katsuki reached over and pulled the lollipop from Izuku's mouth and stuck it into his own.

Midoriya pouted then, which made Bakugou's groin burn in want. That mouth, those lips, should be doing something other than pouting at him. "Kacchan, that's mine."

Bakugou grinned, and leaned down so their noses were almost touching. Izuku swallowed but dared not move. Bakugou opened his mouth, pulled the lolly away and returned it to Izuku's now pursed lips, loving the way the other boy shuddered slightly. "Couldn't help it, Deku." He twisted the stick and it pushed forward, forcing the sweet back into Izuku's mouth. "You looked too fucking cute with something in your mouth."

Midoriya's face blushed a dark red that rivaled Katsuki's burning eyes. "Kacchan…" he tried to speak, but stopped when Bakugou grabbed his wrist and pressed his hand into the erection straining against the pants of his uniform.

Bakugou leaned in further until his lips were against Izuku's left ear. "I can't wait to see you with something bigger."

What happened next was a blur. Katsuki pulled Midoriya from his seat and dragged him towards the elevator. Izuku did all he could to avoid tripping over his own feet as they moved, his heart beating so fast he could no longer feel it in his chest. Waiting for the elevator didn't take nearly as long as he hoped, the doors sliding open almost as soon as Bakugou had pressed the button.

The moment those doors had shut and the box began moving upwards, Katsuki was on the other boy, grinding his knee into his groin with an unnecessary amount of force. Izuku's whimpers were cut off when Katsuku pushed his tongue into his mouth, sealing away any noises of protest with an angry kiss.

Whilst Midoriya let his eyes fall shut as he attempted to kiss back, Bakugou kept his vision trained on the small screen above them, watching the numbers slowly roll across until it finally rested on the fourth floor. He pulled away just as the doors were opening, and didn't wait for them to stop moving before pulling Izuku back out and towards his room.

"Kacchan, wait!" Midoriya was already panting, and tried to pull Katsuki backwards in an attempt to stop them from walking. "I get this is that quirk, but do you really want to do this?"

Bakugou turned to face him, fury burning in his eyes. When he spoke, his words came out as a growl that made Izuku want to shrink into the floorboards. "That's none of your damn business, Deku." He took a step forward and grabbed the collar of Izuku's shirt with his free hand. "But thanks to you I'm fucking horny. So you had better get in that room and do something about it."

Midoriya nodded silently and allowed Bakugou to drag him the rest of the way down the hallway and into his room. Katsuki slammed the door shut once they were inside and pushed Izuku forward towards the bed, pushing him to his knees and unbuckling his belt as he loomed over the boy. "Ka- Kacchan!"

"The fuck is it now?" Bakugou snapped as he took a seat on the bed before Midoriya, spreading his legs so his thighs were on either side of his head.

Midoriya swallowed as he looked at the bulge in Katsuki's pants, the sight sending waves of heat towards his own cock but he tried to push those feelings down. "You promised you wouldn't force me to do anything like this." His voice came out as a whisper, terrified to anger the boy above him.

Bakugou ground his teeth together as he raised his arms, aiming his palms, now popping with small explosions, towards Midoriya's face. "Fucking nerd." The insult was short lived, as he leaned forward and grabbed the back of Midoriya's head with both hands. He didn't wait for a complaint before their lips were pushed together again, his tongue slipping into Izuku's mouth at a much more gentle pace than the elevator.

Midoriya gripped at Bakugou's thighs to keep himself balanced, as he completely lost himself in the kiss. There was something about it all, the way Katsuki's lips moved against his own and the way they felt. They were chapped and rough, the opposite to they way they had felt the Friday of last week. They felt as if he had been chewing on them for days on end, and Izuku couldn't help but wonder why.

He was soon dragged from his wandering thoughts however, from the sensation of Katsuki biting at his bottom lip. "Kacchan…" He meant to cry it out, but the name escaped as a moan, catching Bakugou off guard.

"Do you like this Deku?" He asked in curiosity.

"I don't know." The reply didn't satisfy however, and Katsuki pushed Midoriya forward until he was flat on his back, sprawled out on the floor. Bakugou stayed on top of the boy, rolling his hips forward into Izuku's as they continued to kiss.

Katsuki licked Midoriya's lips to encourage them to open, grinning slyly as he did so. "Feels like you do. Feels like you want it bad." Midoriya did nothing to fight back, he didn't want to. He loved the feeling of their clothed members grinding against each other, and he began bucking forward to chase the friction. "Tell me Deku," Bakugou pulled away from the kiss to speak, but made no move to stop rolling their hips together. "Do you feel forced? Do you want to stop?"

Izuku squeezed his eyes shut and propped himself up onto his elbows. He shook his head furiously before finally looking at Katsuki, staring directly into his eyes. "I don't want to stop Kacchan. But do you really want this?"

Katsuki said nothing as he thrust a hand forward to grab the side of Izuku's face. He brought it to his own and kissed the boy again, shifting their positions as he did so. It was awkward work, but Bakugou was soon back in a sitting position with Izuku laying in between his spread legs. Their mouths were still pressed against each other, a mess of saliva and tongue. Midoriya couldn't help but let out small moans each time Katsuki bit or sucked on his bottom lip, the sounds spurring Bakugou to continue the work.

Midoriya was desperate for more of that kiss, but he could feel Katsuki's hardening cock pressing against his stomach. He pushed lightly against Katsuki's shoulders to pull himself away, Bakugou reluctant to let him go. "The fuck is wrong with you now?"

Midoriya swallowed thickly, keeping silent. He kept eye contact with the boy as his hand moved down to fumble with the button on his pants. Katsuki's breath hitched, though he let out a low growl to cover it up. There was no way in hell he would give Izuku the satisfaction of seeing him come undone.

"Kacchan…" Midoriya slipped his fingers underneath the fabric and began stroking Bakugou's length through his underwear. It was hard, and there was already a small, wet patch growing where the tip of his cock strained against the clothing. "I want to make you feel good, if you'll let me try."

Bakugou glared down at Midoriya who was lowering himself towards his aching erection, silently begging the boy to hurry up. No words were spoken as Midoriya hooked the fingers of both hands under his pants, and inched the clothing down, pulling his underwear along with it. Midoriya finally looked away from Katsuki's face when he felt the clothing give way to what it had been hiding. He looked down in time to watch the large cock spring free of its confines and slap against Bakugou's stomach.

The blush spreading across Izuku's features was far too arousing for Bakugou to keep still, as he reached down to give himself a few long, slow strokes. Izuku licked his lips as he watched the motion, pushing down the panic boiling over his thoughts, back to a place where he could ignore it. He wanted to try, and so he allowed himself to get closer.

Kirishima had done this, Bakugou had done this to Izuku himself. How hard could it be?

Watching his every move, Katsuki smiled a shit eating grin. He's finally going to do it. He angled his cock towards Izuku's mouth as those lips parted, taking the head into that wet heat Katsuki had been longing for. He could feel Midoriya's hesitance, could feel the boy shaking but said nothing as he continued to stroke himself.

Izuku's tongue, which had at first been stuck to the roof of his mouth, ran over the tip once before stilling on the underside of the head. Midoriya looked up momentarily, long enough to see the hunger blooming in Bakugou's eyes. This was okay.

Izuku squeezed his eyes shut and pushed himself forward slowly, feeling the erection fill his mouth until it hit the back of his throat. He choked, pulling back at once and cracked an eye open.

"Is that it?" Bakugou growled from above him. Izuku had only just managed to take half of his length into him, and had choked on the first try.

Izuku pressed his lips to the tip in a brief kiss before speaking, "It's too big, Kacchan."

Bakugou glared at him and grabbed a fistful of green hair. "Kirishima doesn't fucking complain."

Those words sparked something inside Izuku who opened his mouth once more. Katsuki was right, Kirishima didn't complain. Eijirou had said himself that he takes the whole thing, without a seconds thought. Closing his eyes again, Midoriya pressed forward, though not as far this time to avoid gagging. He tried to think back to how Katsuki had sucked him off the first time.

It had been fast, rapid movements. That was the main thing Midoriya could remember, so he began to mimic those memories. He bobbed his head faster, holding himself steady with his hands braced against Katsuki's hips. His tongue, still pressed against the underside of the cock, made it impossible for Izuku not to taste the precum leaking over. The low groan that escaped Bakugou made Izuku almost smile, and he pushed the cock to the back of his throat again, taking all he could for a split second before pulling off to continue his shallow movements.

"Fuck." Bakugou let the curse slip out as he let his free hand join the other in Midoriya's hair, curling his fingers through the locks. He had a tighter than necessary grip, he knew, but he needed it. Katsuki could feel Midoriya begin to pull off completely at the sting from his scalp, and Bakugou took this chance to force his head downwards onto his cock, only stopping when he felt Midoriya's nose press against his pelvis. "Oh fuck." Izuku tried to pull away, gagging around the intrusion which sent amazing vibrations straight through Katsuki's length. "Not yet."

Midoriya whimpered and Katsuki finally let him move. Izuku pulled off completely now, coughing and trying to pull Katsuki's hands away from his hair. "Kacchan, why-"

His words were interrupted as Bakugou pulled him forward again, this time thrusting up into his mouth simultaneously. He didn't hold him there however, but pulled him back again only to thrust forward at a brutal pace. It was easier to push Midoriya's head down as he fucked his mouth, no matter the noises coming from him. "Take it Deku," he grunted, biting down on his lip. "Moan for me, let me hear you." Izuku happily obliged, despite the pain burning in his throat. He allowed himself to moan at the feeling, embarrassed at the way it quickly became a whimper. "Fuuuuuck."

Izuku needed to breath, and he began a rough tap against Katsuki's thigh in order to get his attention. It didn't work, Bakugou ignoring the wordless pleading in favour of thrusting faster. "I'm gonna cum Deku."

These words made Izuku panic, and he pushed against Bakugou's wait. After a second, he realised this would get him nowhere fast and so he gave one final push, activating his quirk as he did so. The sudden surge of power caught Katsuki off guard and he felt himself cum as Izuku finally pulled his head away.

The boys went still as Izuku's lips and cheek were painted white with semen. He held a hand to his throat which still stung from the abuse, yet he still managed to smile. He had made Katsuki cum, and this time, no one had been forced into this.

Izuku was happy. He was happy even as Bakugou pushed him away to pull his pants back up. Happy enough to watch the blonde stagger to his feet and turn towards the door without looking back. "Get yourself cleaned up, you're filthy."

Izuku nodded in response before realising Katsuki couldn't see him. "Yes Kacchan."

Bakugou opened the door but paused before stepping out. "I'm going to the bath, I better not see you there." As he spoke, he finally looked over his shoulder at Midoriya. "If I do, I'll kill you."

The door slammed shut and Izuku smiled down at himself. "Yes Kacchan."

It was oddly peaceful in the bath, not to mention lonely without someone to talk to. Though he would never admit that. Eijirou had been alone since he walked in, assuming the others had already finished. Either that or were using their own, private bathrooms. Kirishima, however, had decided that he would rather soak in the steaming water instead.

The alone factor didn't last forever though, hearing someone busy themselves in the change room beyond the wall. Kirishima let the noise filter through to the back of his head as he kept his eyes closed, focusing on the heat of the water. That is, until whoever it was rounded the corner.

"Of course you're here." Kirishima cracked open an eye to peer at Bakugou as he stalked towards the edge of the bath. "It could have been anyone else, but it just had to be you."

From this angle, Kirishima could almost see what was hidden underneath Bakugou's towel, and he closed his eyes against the view. It wasn't as if he was embarrassed, but this wasn't exactly the time to be staring at his friend's junk. He ignored whatever Bakugou was saying now and opted to listening to the sound of the water splashing up out of the bath as Katsuki joined him.

He didn't want to be alone, but he wasn't exactly begging for company from the boy who had just avoided him for the past three days. Eijirou wasn't petty, that wasn't his thing, in all honestly he wasn't entirely sure what was running through his head.

All thought was diminished when he was hit with a faceful of water however, and he spluttered a moment before finally turning to glare at Katsuki. "Bro, what was that for?"

"For ignoring me," came the blunt reply. He watched Kirishima, as if waiting for something.

Eijirou gave him a questioning look. "I didn't realise you wanted to talk to me."

"Who else would I be talking to?" Bakugou was clenching his fists, visibly holding himself back. "You're the only one here, hair for brains.

Kirishima turned away, looking down in slight embarrassment. "Sorry Bakugou. What were you saying?"

Katsuki rolled his eyes. "I said fucking Deku doesn't know how to suck dick." Kirishima made a choking sound as he whipped around to stare at the other boy. "You wouldn't look so surprised if you had been listening in the first place."

Kirishima held up both hands as he finally gave Katsuki his full attention. "Wait, you mean he sucked you off?"

Bakugou grimaced. "Not really, he put his fucking mouth on it, but didn't exactly do much." Eijirou was about to ask him what he meant, but he was clearly pissed off about it enough to begin a short rant. "He barely took any of it, and didn't do anything with his tongue. It was like he was stuck in one spot." He lifted his arm and parted his lips for a moment, letting his tongue rest against his bottom teeth. Kirishima tried to hide the blush in his cheeks as Katsuki began pumping his fist in a backwards and forth motion, imitating a blowjob. It only lasted a couple seconds, before Bakugou slammed his fist onto the surface of the water. "That was it! A few small bobs of the head and he thinks that's enough to make me feel good! You on the other hand…"

He made eye contact with Kirishima who suddenly felt as if the bath had shrunk considerably in size. "What do you mean?" He tried to back up, almost flinching as the edge of the bath pressed against his spine, and watched, wide-eyed as bakugou slowly waded toward him.

"Get out and I'll show you." Katsuki spoke in a calm but firm voice, enticing Kirishima to follow his order. "Sit on the edge."

Eijirou did as he was told, pulling himself out of the water, watching the pink tongue dart out to lick Katsuki's lips as he eyed Eijirou's half hard member. This is when something clicked. "Bakugou, wait…" Kirishima covered himself with both hands as he spoke, not liking the look Katsuki was giving him. "I know this is that quirk, but-"

"It's not that quirk!" Bakugou snapped and lunged forward. He closed the distance between them in the blink of an eye, wrapping one hand behind Kirishima's neck whilst the other popped with tiny explosions mere inches away from his face. "This is not that fucking quirk, I've already ejaculated. That's what I was doing all weekend, figuring out what causes it." He lowered the popping hand and pulled Kirishima's hands away. "Right now, I want to show you, what you need to teach Deku."
