So I'm a fan of Bakugou flirting style just being "I wanna touch you so I'm gonna touch you" like I know that's not the healthiest thing but Bakugou isn't the healthiest person. Kirishima is so openly touchy with him it just made sense to touch him back.

It starts out small.

Bakugou tapping or hitting Kirishima's shoulder to get his attention, smacking him on the head when he doesn't get some thing Bakugou spent the last hour teaching him... Then brushing up against Kiri when he walks past him.

One day Kiri comes to the common area with his

Hair down and Bakugou sits next to him and just quickly runs his fingers through it. Bakugou mumbles "soft" and then retreats to his bedroom.

Kirishima, being the adorable himbo he is, is oblivious. Even when the bakusquad points it out, kiri's like "nah he's just my bro"

Then Bakugou's touches start to linger. He touches Kirishima's shoulder while they're studying and trails his fingers down kiri's spine, the touch is so light he barely feels it. When he looks at Bakugou, the blond is blushing and won't meet his eyes.

So to make his bro comfortable Kiri does the same touch back. Kiri thinks he's being nice, Bakugou take it as Kiri accepting and returning his feeling.

The touching changes.

Kiri is caught of guard when it happens. He and Bakugou are the last ones in the changing room,

They're getting ready to shower. Kiri pulls his pants down when he feels a light touch on his ass cheek. Kirishima squeaks and freezes, looking over his shoulder to find Bakugou. The blond is staring back at Kiri as if he is challenging him and then squeezes his ass HARD.

Kiri falls forwards, his hands catching himself against the lockers. Bakugou must hums and walks away.

Kiri tries to rationalize it, guys spank each other playfully in the locker room... Maybe Bakugou was trying to do that but grabbed him instead? Didn't make sense but Kiri

Rolled with it. Plus Bakugou acted like it never happened.

A few days later they were studying together during class, Bakugou and Kirishima's desks were pushed together in the back of the room. Kirishima was in the middle of asking a question when Bakugou's hand landed on his

Thigh, too close to his crotch. Bakugou's pinky finger was touching the place where Kiri's leg connected to his body. The blond shot him the same challenging look. Kiri stammered for a second but tried to act normal, his face red as Bakugou massaged his thigh. Kiri began to sweat

Biting his lip to keep from panting. Kiri's pants were too tight and he couldn't focus. How was Bakugou unfazed? The blond was still working normally, writing causally with his left hand as if he always write with it while his other hand moved to Kiri's inner thigh and squeezed.

Kiri yelped and stood up, grabbing his textbook to cover the tent in his shorts and announced too loudly that he would finish the rest in his dorm room. He left the classroom, ignoring Iida's protests, and felt Bakugou's stare burning into his back.

Kirishima stopped at the closest bathroom, and jerked off into the toilet to the memory of hand on his thigh.

Kirishima was a mess and he didn't understand what was happening. When he saw Bakugou later the blond just smirked at him and walked away without saying anything.

Kiri tries for /hours/ to finish his homework by himself, he even texts the rest of the bakusquad but they're no help. Nervously, Kiri grabs his books and goes next door. It's already 10pm, Bakugou probably wasn't awake, but Kiri has to try. Bakugou answers after the third knock

The blond is only wearing compression shorts, and he has bed hair. Kiri apologizes and points to the textbook, Bakugou let's him inside.

Kiri sits on the floor and Bakugou sits entirely too close with one arm drapped over kiri's shoulders. Bakugou skin smells sweet,

But his slightly damp hair smells like men's shampoo. It's distracting.

Also Bakugou is so close their cheeks are almost touching...

Kiri is trying so hard not to pop a boner. His thin pajama bottoms left /nothing/ to the imagination and he regrets wearing them.

Bakugou's hand starts running down the side of Kiri's body, landing on his hips and pulling him closer, while Bakugou's thumb slides under his shirts and rubs circles on his skin. Kiri shudders, he's breathing heavily and his heart is racing.

Is he imagining things or is Bakugou staring at him? Kiri wants to check but if he turns his head their lips will probably end up touching.

Bakugou is still explaining the problems to him, but he can barely listen over the sound of his heart.

"Solve for X, shitty hair"

Was it just him or did Bakugou sound breathless? Kirishima couldn't think about it too hard because Bakugou's other hand started roaming, squeezing Kirishima's knee. Bakugou's bare chest was pressed against Kiri, his muscular but soft tits rubbing against Kiri's arm.

"Solve for X" Bakugou repeated. For some reason his voice reminded Kirishima of a porno. /fuck/.

"I...uh..."

"Have you even been paying attention?"

Kirishima's swallowed thickly, he was definitely in danger of drooling right now.

"I-is it hot in here?" He managed to say

"No? Are you getting sick?"

Oh his bro is just concerned...

"N-no I don't think..."

"Let me check, shitty hair"

Bakugou's hands were off of Kiri and he let out the breath he has been holding. But the relief was short lived. Bakugou grabbed his chin

And forcibly turned his head. Then Bakugou pressed their foreheads together, red eyes staring deep into Kirishima's. The blond put his hand on the ground between Kirishima's legs to lean into him more, his forearm brushing against his leaking hard on.

...This was too much...

"/Bakugou/" Kirishima grunted, as his body tensed. His orgasm hitting out of nowhere like a sucker punch in the face. Cum leaked through the thin material of his pants. There was no way Bakugou didn't feel that... In fact Kiri knew he did, because right when it happened

Bakugou's eyes blew wide and he pulled back, staring at the red head's face as he came.

"Holy shit" Bakugou breathed.

"I... Fuck... Sorry!" Kiri yelled, jumping up and running out of the room, wishing the ground would just open up below him.

"Then I just yelled sorry and left" Kirishima groaned, banging his head against the lockers.

Kaminari and Sero just stared at Kirishima, stuck between laughing at what happened and trying to sympathize.

"He does touch you like /a lot/" Kaminari said after an awkward

Silence. Sero nodded in agreement.

"He's my bro that's what bros do" Kirishima whined

"Kirishima, we're bros and I don't /grope your ass/ while you're changing" Sero said, patting Kirishima on the back "he's clearly into you dude"

"You should tell a teacher if you don't-"

Kiri turned away "there's nothing to tell! We're bros it's /fine/"

"He literally eye fucks you all the time" Sero muttered

Kirishima turned as red as his hair "h-he does /not/"

"Just ask him, I'm sure he'd admit it" Kaminari shrugged

"I-i can't just ask him /that/"

"Sure you can"

"Here we'll do it for you!"

"What?"

"Oi, kachaan!" Kaminari called over Kirishima's shoulder.

"What do you want dunce face?" Bakugou grunted

"Nothing!" Kirishima squeaked, his voice cracking as he spun to look at Bakugou "he doesn't want anything, it's dumb"

"Do you eye fuck Kirishima?" Kaminari shouted over Kirishima

Bakugou scowled, looking at Kaminari then at Kirishima before a smug look twisted across his face.

"Yup" he replied, accentuating the p with a little pop as he stripped out of his hero costume.

Everyone was frozen, watching as Bakugou causally went about his business.

"I-i didn't think you'd actually say it" Kaminari broke the silence, shifting his weight uncomfortably.

Kirishima made a strangled gargling noise before mechanically walking out of the locker room.

He didn't even have his shirt buttoned as he walked down the hall to the bathroom in a daze and the promptly jerked off for the third time that day in one of the stalls. Kirishima was about to finish when the door to the bathroom opened with a bang.

"I know you're here"

Bakugou's voice came from right outside the stall. Kirishima froze, hand mid stroke, and held his breath as best he could.

"Shitty hair I can see your damn shoes"

"Ba-Bakugou" Kirishima yelped "I'm taking a piss I'll meet you la-"

"You're not pissing, I can hear you."

The stall door shook.

"Dude! My pants are down! I- uh..."

"Open the door." Bakugou's voice was calm and commanding, it sent a shiver down Kirishima's spine and he had to bite his tongue to keep a whine from bubbling out of his throat.

"I-I'm not done yet!"

"/Kirishima/" Bakugou sounded cold and threatening. Kirishima gripped his cock tighter.

"I'll see you later! Please, Bakugou" he whined, sounding desperate and needy as his hips thrust into his hand.

"Fine" the blond spat, stomping out off the bathroom and slamming the door.

"/oh fuck/" Kirishima moaned, throwing his head back as he moved his hand rapidly. He came with a shout, back hitting the stall door as he painted the wall with ropes of cum, hitting everywhere except the toilet. Kirishima cursed himself as he caught his breath. What a mess...

Kirishima went straight to his room and locked the door. He needed to stop jacking off to the thought of his best bro, it just wasn't a manly thing to do. But Bakugou kept saying and doing things to mess with him...

Kirishima was losing his mind.

He tried to take his mind off of things by working out for the next few hours. To Kirishima's relief it worked, by the time he was ready to stop it was already 830. Bakugou would be asleep and Kirishima could apologize for not coming over when he woke up tomorrow.

Kirishima collapsed in the bed with a satisfied smile and closed his eyes... And then he open his eyes and stared at the ceiling until it was about 11. Thoughts bounced around in Kirishima skull, all of them were about Bakugou. Kirishima cursed and paced around the room.

He was never going to be able to sleep like this. He needed to know /why/ Bakugou was messing with him.

Without thinking Kirishima knocked on the wall connecting his room and Bakugou's until he heard the blond grunt.

"Bakugou are you awake? Can I come over?"

Kirishima held his breath until he heard another softer grunt. He smiled, quickly changing out of his sweaty clothes and pulled on compression shorts and a thick pair of sweats the be knew would be better at hiding his inevitable arousal.

He knocked once to let Bakugou know he was coming in before opening the door. Kirishima was confused why it was still dark in the room, but he closed the door quickly before searching the wall blindly for the switch. Hands grabbed Kirishima's hips and slammed him back against

The door. If it weren't for his sweats Bakugou's nails would have broke skin.

"Bakugou!" Kirishima hissed, hands flailing on the darkness in front of him, but Bakugou's head wasn't at face level.

"You don't seem to get it so I'm gonna spell it out for you"

Bakugou's breath was hot against Kirishima's stomach and he felt the blond's thumbs hook into the waistband of his sweats and underwear "You don't have to do anything. Just stand there and /take it/."

Oh god Kirishima should've masturbated again before coming over.

"Ba-Bakugou?" He whined, his head leaning against the door with a thud, hardened fingers digging into the wood "Come on man I don't understand this game."

"Shut. Up." Bakugou growled, teeth scraping against him

Bakugou pulled Kirishima's clothes down, freeing his throbbing erection. The blond grabbed it roughly in his hand and Kirishima cried out at the contact, doing his best not to let his hips move.

Bakugou pressed his noses against Kirishima's skin and inhaled deeply.

"You're fucking rank" he hissed, but there was no anger in his voice.

"I-I was working out in my room" he felt the need to explain himself "I haven't showered"

"I know. I heard." Bakugou inhaled deeply again "I jacked it to the sound of you"

Kirishima.exe stopped working.

Bakugou slowly started stroking Kirishima's length slowly, his head moving lower until Kiri felt his nose brush against his balls.

"Bakug- oh /fuck/" Kirishima was cut off by the sensation of Bakugou's tongue, hot and wet licking between his balls.

A loud crack sounded through the dark room as Kirishima's hardened hand broke the door. Light from the hallway seeped in, and Kirishima was finally able to see Bakugou's face as the blond kneeled before him.

Bakugou was naked except a thin pair of boxers that had been pulled

Down to expose his tight ass. He looked fucked out, eyes half lidded and dilated. Bakugou's pale skin was shiny with sweat and his cheeks were flushed in a way that made his freckles stand out. He looked like he was straight out of one of Kirishima's wet dreams.

"Oh god"

Bakugou smirked and sucked one of balls in to his mouth while rubbing circles around the head of his cock, maintaining eye contact the whole time.

"'M not gonna last" Kirishima whimpered, bucking into Bakugou's grasp as the blond hummed around him.

Bakugou released Kiri with a lewd pop, licking his swollen lips "I didn't expect you to"

"I don't understand" Kiri moaned through gritted teeth and Bakugou pumped him faster

"You're thinking too hard" Bakugou grumbled and stuck his tongue out by kiri's slit, catching the pre that had collected there and was starting to drip.

"Oh my God, /Bakugou/" Kirishima whined, carefully running a hardened hand over the blond's cheek leaving a trail of red lines

Bakugou's looked up at him, tongue out and mouth open wide. The image sent Kirishima over the edge, his eyes rolled back as he accidentally grabbed the side of Bakugou's face and pulled him closer. His fingers scratching Bakugou as he came all over his tongue and in his mouth.

Bakugou pulled back, a string of spot and cum connecting is tongue to Kirishima's cock. He slowly curled his tongue back into his mouth and swallowed thickly, opening it again to show Kirishima that he had drank it all. Kirishima's cock twitched and he squirmed, unsure what to do

Then he noticed the tent in Bakugou's boxers.

"C-can I help you with that?" Kirishima asked sheepishly.

Bakugou wiped some stray cum from the corner of his mouth with his thumb and sucked it off before saying "No, get out"

Kirishima was a zombie the next day. After Bakugou kicked him out the blond had spent at least an hour loudly jerking off, moaning desperately as the bed squeaked and banged on the wall. Kiri had to cum against before he could sleep, and even then he slept for a total of 30 min.

He didn't even style his hair when he went to class, Mina and Kaminari shot him worried glances as he nodded off during that day's lessons. Every so often Kiri would glance at Bakugou, make eye contact, and his mind would conjure the image of Baku at his feet mouth full of cum.

Kiri would get painfully hard. He took so many bathroom breaks th at Aizawa was visibly frustrated with him.

After class Bakugou left without talking to Kiri, but made a point to push past him in the doorway. Baku's firm, round ass grinding against Kiri's crotch when he passed.

Kirishima almost ruined another pair of boxers. Bakugou shot him another smug and challenging look over his shoulder. Kiri was thoroughly confused.

"I just don't get it..." Kiri said with a yawn, his head was in Mina's lap while they sat in the common roon "What does he want?"

Mina looked frustrated and a little grossed out after Kiri caught her up what was happening.

"He's clearly messing with you. He's a sadist"

"I guess... But what do I do?"

"I don't know Kiri, you could stop it if you wanted to but you won't. You're a masochist"

Kiri frowned at the foreign word but he was too tired to think about it.

"He says I'm thinking too hard"

"You probably are" Mina poked the crease between his brows "You're gonna give yourself wrinkles"

"You're not being helpful"

Mina shrugged and Kiri sighed.

"I'm gonna go take a bath" Kiri grumbled rolling onto the floor before standing "maybe that'll help clear my head"

"And go to bed early" Mina called after him "you look like death"

"Gee thanks..."

Kirishima took his time washing up. It was too early for anyone else to be in the baths, and Kiri appreciated the time to be alone and think.

Thinking too hard? That didn't make sense. Nothing Bakugou did made sense. Kirishima thought, pouring water over his head to rinse away

His shampoo. When he was clean he sunk into the baths, the water close to scalding but it felt so good as he sunk in deeper. Kiri was so relaxed he could hardly move, the back of his head rested against cold tile as he struggled to keep his eyes open.

Cw: noncon to con, somno

Kirishima must have drifted off as some point because he woke up with something weighing heavily in his lap. His head had been propped up and some thing was touching his lips lightly. The touches were gentle, barely there, like whoever was doing it was trying not to wake him.

Kirishima groaned and the person froze, but Kiri was too tired to care or open his eyes, so after a few seconds the touches started up again.

The touches felt nice, almost ticklish up and down his body, around his lips, necks and chest as Kiri drifted in and out of consciousness

He probably would've stayed asleep if not for the hand getting bolder and pushing past his lips and into his mouth. Kiri scowled, arching his back as he tried to stretch, but the weight and hands held him in place.

"Wha-?" He mumbled around the thumb in his mouth.

Kiri opened his eyes and found Bakugou sitting in his laps, holding his head of up as he pressed down on kiri's tongue with his thumb. Bakugou had a hungry look on his face, his pupils were so dilated Kiri could barely see any red and he was panting.

"Shh" he breathed "it's ok"

Bakugou opened kiri's mouth wider, running his thumb along the points of his teeth.

"I can see you thinking" Bakugou said, replacing his thumb for two fingers "I told you it's fine, calm down. I locked the door."

That's not want Kiri had been worried about but ok...

Bakugou stopped holding kiri's head up and pushed his hand between their bodies. His hand wrapped around both their erections and squeeze, Kiri gasped.

"Like I said just sit there and take it" Bakugou smirked, biting his lip as he began to stroke them together.

"Oh gaw" Kiri slurred around the fingers weighing heavily on his tongue "pwe- ACK"

Bakugou cut Kiri off by forcing his fingers to the back of his throat making him gag.

"You never listen. Don't think and shut up."

Kiri did his best to nod while Baku fucked his face with his fingers, trying not to gag when Bakugou got the back and pushed deeper. His other hand sped up around their lengths, swirling around the head before sliding down. The feel was overwhelming.

Kiri didn't know what to do with his hands. Bakugou hadn't said if he could touch him, so he gripped the edge of his seat. Trying to keep his eyes open and focused on Bakugou's face.

"That's right take it" the blonde moaned "You're mine you got that. /mine/"

"Yours" Kiri agreed between gagging sounds, drool spilling out of the corners his mouth. "Yours"

Then everything was gone. Kirishima whined as Bakugou stood up, water cascading down his beautiful body. The blond fisted his own cock and grabbed kiri's hair roughly.

"Don't fucking cum" Bakugou hissed, pressing the head of his length to kiri's lips.

Kiri squeezed the base of his dick hard, opening his mouth for Bakugou. He looked up at the blond through his eyelashes waiting for him to finish.

Bakugou came with a bitten off curse, Kiri just barely managing to harden before explosions went off on Bakugou's palms.

Most of it missed Kirishima's mouth and got all over his face, Kiri had to close his eye to avoid getting cum on it. Bakugou admired his work as he came down from his high, mumbling that he wish he had brought his phone. He nudged kiri's throbbing cock with his foot and smirked.

Bakugou leaned down and licked a stripe up kiri's cheek, collecting his own spend with his tongue before shoving it deep into kiri's open mouth. Kiri recoiled, surprised, but Bakugou's firm grip in his hair kept him still. When he pulled back he placed a finger under kiri's chin

And pushed his jaw shut.

"Swallow."

Kirishima complied, his eyes still wide.

"Good boy."

Without another word Bakugou left. Kiri's cock still hard and leaking, cum still all over his face and hair, still confused about what was happening.

Kirishima didn't see Bakugou until the that weekend. He had tried going to the blond's room but no one had answered. So Kiri spent the rest of the night jacking off and coming up with a game plan to corner Bakugou and get him to actually talk.

Talking at school would be the best strategy, lower chance of Bakugou seducing him, but to kiri's dismay Bakugou wasn't at school the next day.

So Kirishima had made some breakfast (scrambled eggs and rice, nothing fancy) and stood outside Bakugou's door, squirming as he waited

Bakugou opened the door, looking Kirishima up and down before stepping aside and letting him in. Kiri set the bowls down on the desk and turned to face the blond, the words he wanted to say prepped and ready to go, but he didn't get a chance to speak.

Bakugou's mouth was on his in a second, swallowing kiri's surprised yelp as he walked the red head backwards towards the bed. Kiri's legs hit the side and they toppled over, Bakugou on top, his mouth unrelenting.

Kirishima very quickly forgot why he had originally come over.

He moaned and let Bakugou's mouth dominate his own as they ground their hips together. Fuck Kiri was gonna cum in his pants.

"Bakugou" Kiri gasped, pulling back so he could breathe as Bakugou's lips chased his own "Bakugou stop I'm gonna cum"

"Already? What are you a virgin?"

"Bakugou" Kirishima whined and turned his head away. "I'm being serious"

The blond began assaulting his neck instead, starting right below his ear and kissing down his neck. When Bakugou finally pulled his lips we're swollen and shiny with spit.

"You /are/, aren't you?"

Bakugou's expression was dark and hungry as he looked down at Kirishima like he was going to eat him.

"Y-you're acting like you're not" Kirishima stammered, squirming under Bakugou's gaze.

"I'm not" Bakugou said, sliding his hands under Kirishima's tank top.

He squeezed Kirishima's pecs and pitched his nipples, rolling them between his fingers. "I'm gonna make you feel so good, Kirishima"

Bakugou leaned down and starts mouth Kirishima through his pants as the red head writhes underneath him, moaning and whimpering.

"Bakugou please" Kirishima whined, unable to stop his hips "w-wait"

"I told you I'm gonna make you feel good, Kirishima, just relax."

"Bakugou I'm being serious!"

"Kirishima..."

"I don't understand why you keep doing this with me."

"I'm doing this to make you feel good. We're dating, that's what boyfriend's do."

"W-we are?"

"Yes."

"Since when?"

"Since I said so. You're mine, Kirishima."

Kirishima frowned and pushed Bakugou off the bed.

"What the hell!?"

"Bakugou you can't just /claim/ me! That's not how this works!"

"Yes it is."

"What? No it's not!"

"'S how my mom started dating my dad. 'S how I started dating you. I said you're mine and you agreed."

"I-I... Bakugou I would like to be asked instead of told..." Kirishima mumbled, adjusting his tank top.

Bakugou muttered and then sighed "ok. Do you want to be my boyfr-"

"Yes"

Bakugou shot Kirishima a glare before smiling.

"I don't see why you wanted me to do that if you were just gonna cut me off, but /now/..." Bakugou grabbed Kirishima's ankle and dragged him closer "I'm gonna make you feel good."
