Katsuki knew perfectly well that he was a total brat.

He knew that with Eijirou watching him like that, his gaze smiling to whatever dumb shit Mina was going on about but his eyes burning holes into Katsuki's skull.

He knew he fucked up.

He knew he was pushing his luck.

And, well, if he wanted to deal with whatever his boyfriend had in mind he would but for the time being he was going to be a brat.

He was in a mood and the thought of Eijirou not being so gentle with him later might have just egged him on.

It started with a fight with Deku, shocking literally no one. They might have gotten better, getting over their differences and Katsuki going to therapy regularly, the nerd accepting the apology for years of bullying.

It might not have been a great friendship or anything but they were able to work through a lot, and really Katsuki knew how shitty he was then and didn't think Midoriya would even listen to the apology.

But they worked things out, healed, and kept up the work they put into therapy.

So the relationship between them was more like siblings… on a road trip and having to sit beside one another. Arguing on stupid shit, and being way too fucking loud for anyone around them.

This time was no different.

Deku muttering too fucking loud and Katsuki was too fucking annoyed at the moment. He had been unable to fucking focus on the book he was trying to read so he yelled at the nerd.

"Fucking shut the hell up you waste of damn oxygen!" Katsuki shouted.

Deku looked up not even noticing how long he was being annoying. He looked over to Katsuki, confused. "I wasn't even talking to you?"

The fact he made the statement a question just threw him off the cliff. Katsuki was up from the couch and rushing over to him in seconds. He was too fucking overstimulated for this shit.

Deku was used to this by now. They argued, they fought, and it was as close to a truth as Katsuki ever thought they would get. Dealing with the shit he said and did in middle school and not to mention the fact Deku actually forgave him which seemed more than he deserved.

"Why are you such a bitch?" Midoriya questioned blocking the punch to his face.

Katsuki clenched his teeth together. "Why are you?!"

They both started yelling, Katsuki landing a hit only for Deku to hit him right back in a game only the two of them knew how to play. Sure, Katsuki could assume they looked like they did when they were kids arguing over who got the All Might toy but he was still pissed off so what better way to deal with his anger.

By the time Aizawa broke them up for the third time that week Katsuki had stepped back anyway. He ignored the comments from his classmates.

The same classmates who would most likely bet money he worked with the damn villains because he was mean, aggressive, and because of his quirk. Fuck them.

All of Deku's little friends were all talking to each other muttering under their breath about him.

"I don't know why you put up with him?" Tsu muttered with a ribbit afterward.

"You don't deserve that," Ochaco added.

And fuck that.

Katsuki knew he was a total fuck up. He knew that no matter what he did he was the worst in the room—okay well he was better than the fucking grape bitch but the bar was low with that topic in general.

So he faked it all.

Until it felt like the only way to be.

He had to be the best, because really what else did he have? He wasn't nice, and he wasn't going to be anyone's first choice of a friend, the friends he did have were because of Eijirou and he had no idea why the redhead even liked him, let alone loved him.

Katsuki was an awful person, he knew that. He did not fucking need anyone else telling him that, if he wanted to talk about all his fuck ups he would just call his mother, and she would happily tell him he was the worst thing to ever happen to her.

"Fuck you," Katsuki spat.

Tsu crossed her arms. "I think you need to leave now."

Katsuki glared, it was enough to get her to back up but she glared right back until Deku waved between them nervously getting their attention.

"Really it's fine, I was being too loud while he was reading it shouldn't have happened—"

"Just like you," Katsuki cut him off. "Your mom should have swallowed."

Not his best moment.

Katsuki wanted to take it back, he didn't really mean it.

He was just so fucking tired of everyone looking to Deku as some golden child who could do no fucking wrong and looking at Katsuki like he was trash.

He was stubborn and it hurt physically at this point for him to admit he was wrong.

So he turned and walked away bumping into Deku's shoulder as he passed. It would be for the best anyway, they didn't want him there. No one did. He was the content fucking buzzkill of everything.

He was halfway through his dorm door when he was pushed roughly into it almost stumbling onto the floor in the process.

"What the fuck—"

"Yes, what the fuck indeed, Bakugou."

Katsuki froze.

Eijirou was pissed, at least enough to use his last name again.

He thought Eijirou would have given him some time before he came up and Katsuki could sit in his self misery for a while until his best friend made him fucking forget.

Fucking was nothing new to them at least not since he walked in on Eijirou jacking off and instead of leaving like a normal friend would Katsuki walked into the room and shut the door behind him. Leaving with a facial not approved by his skincare routine.

But now in their last year, it was a daily occurrence to get each other off in some way. Sneaking into the other's room, in the showers, sucking Eijirou off only to have him fingering Katsuki until he was screaming into his own hand.

Katsuki knew just how it felt to have his best friend pound into him, soft and gentle. Needing to be fucked to sleep and grounded to reality and not whatever fucked up nightmare he woke up with.

Then there were times Katsuki learned just how good it felt to have an angry Eijirou rail him into the bed, leaving him having to hide a limp the next day. Hardened hands dug into his waist, his ass stinging with a handprint, or even the few times Eijirou fucked him with no prep, stretching his pussy and leaving Katsuki screaming.

Those nights were left when Shouji wasn't on their floor.

However, now Katsuki didn't know what to expect. He knew Eijirou was pissed off. Katsuki knew that he had gone too far but like hell was he going to do anything about it?

"Gods, you're such a dick," Eijirou grumbled.

He locked the door behind him, pushing Katsuki farther into his room and leaving him nearly tripping again. He felt himself flush with embarrassment.

"He was being a dick to me too," Katsuki mumbled. His voice lacked his usual air of confidence. He knew he fucked up.

He knew that he passed the line of being a brat and went to being a total asshole.

Eijirou stayed silent.

For some reason that seemed so much worse. He felt like a cornered animal about to get hunted for sport.

Eijirou pushed him down enough to leave Katsuki sitting on his bed.

"Would it kill you to be good for one day?" Eijirou asked, leaning over him.

Katsuki rolled his eyes at the ridiculous question. "Fuck off."

Two seconds later he realized his mistake.

Wrong.

Wrong.

Wrong.

Eijirou had his hand wrapped around his throat, he could strangle him in seconds if he wanted to, and fuck, if Katsuki didn't just lean into his touch.

The redhead laughed at him.

"Desperate much?" Eijirou asked.

Katsuki didn't have to answer him, Eijirou knew damn well how absolutely soaked he fucking was at the moment.

Eijirou pushed him onto his back, ripping his shirt without bothering to warn him. Katsuki almost asked what the fuck was he thinking but felt a warning hand press him down again. Eijirou cut his shorts and boxers off with a harded hand. His thigh was cut a little, grazed and stinging like a paper cut.

"You asshole—"

Eijirou covered his mouth. "What?"

Katsuki knew better than to talk back, the only word that would be acceptable was their safe word and he was nowhere near having to use it.

So he kept quiet.

He pressed into his touch, trying to press up against the hard dick he knew would fill him soon enough. Eijirou just moved back and chuckled to himself.

"Pathetic cock whore," he grumbled.

Eijirou grabbed Katsuki's phone, unbothered by Katsuki being totally distracted by the sight of Eijirou's bulge in front of him to care about anything else.

Katsuki didn't even notice Eijirou had his phone until it was being shoved in his direction and into his hand.

"Press dial," Eijirou muttered.

He kissed up his chest, taking his time when he got to the scars on his chest. Eijirou always liked them, scars were manly as hell to the idiot and whatever shame he once had was forgotten about when he knew Katsuki would let him get away with just about anything.

"You're going to apologize to Izuku," Eijirou muttered matter-of-factly.

Cue Katsuki frowning at his best friend. He did not fucking need this right now.

Eijirou held him in place.

Katsuki knew the only way he would get out of this was to safe word, Eijirou would get off of him, and let the phone call go, they could maybe even have sex and spend the rest of the night watching something on Netflix.

But Katsuki knew it wouldn't be the same.

He would not get fucked until he was sobbing for it, begging Eijirou to fuck him harder, begging to be used as nothing more than a toy. He wanted something that left a mark, something to make him forget how his own thoughts got the better of him sometimes.

He looked up and pressed the screen.

There was no turning back.

Eijirou smiled. "Try and sound like you're not getting fucked."

Katsuki's eyes widened when he realized what was happening. He thought he would just have to call the nerd and apologize then Eijirou would fuck him like the brat he fucking was. This was something different.

Something the man who didn't want to say anything about the stuff they did behind closed doors to anyone. Eijirou only grinned at him though, kicking his pants off only to settle over top of Katsuki again.

Pressing the phone to Katsuki's ear, Eijirou kissed his jaw, mouthed at his neck, and pressed the head of his cock into Katsuki's needy pussy. Rubbing his dick through slick folds, the sensation was enough to make Katsuki dizzy.

Of course, that was the moment the phone was answered. Because why wouldn't that be the moment the other line answered Eijirou thrust into him? Filling him full in one deleouse slide and Katsuki gasped out at biting his lip to cover the whorish moan wanting to escape his lips.

Eijirou grabbed his thigh, making his place between Katsuki's legs all the more well-known for the blond. Pressing him into the bed and holding him in place. Something the yoga he did in the morning was all the more rewarding.

"Hello," Deku answered, sounding confused as ever.

Katsuki felt the same, what the fuck was he about to do.

"Kacchan, are you okay?" Deku asked.

The blond didn't even want to know how he knew it was him or why he had his number but all Katsuki could focus on was the shit-eating grin plastered on Eijirou's face as he watched Katsuki process what was happening and what he was going to do about it.

He knew Katsuki was going to fail at being quiet for the phone call.

And fuck.

Katsuki knew it should not have been as hot as it was.

"Fine," Katsuki grunted into the phone.

Eijirou started thrusting into him, slow enough it would be muffled on the phone but enough to have Katsuki biting his tongue. The feeling of the fat cock sliding in and out of him really was going to be his downfall when it came to Kirishima Eijirou.

Fuck.

He hated him.

He loved him.

And he was a coward about the second one.

He forgot he was on the phone for a blissful second until Eijirou was pinching his arm. He needed to get the phone call done with.

"Okay, was there a reason why you called me?" Deku asked.

He must have been in his room by now. The chaos and loud chatter of the common room were gone and replaced with soft music Auntie Inko played when she was reading and in Deku's case most likely studying.

"Fuck," Katsuki muttered not quite meaning to say it out loud.

Eijirou bit down on his neck and Katsuki tried to quickly correct himself.

"I wanted to say—what I said earlier," Katsuki tried.

Eijirou only made it more difficult as he picked up his speed. He was practically hitting his g spot with each thrust, Katsuki felt like his whole body was shaking.

He tried not to react to the pleasure, tried to remember why he had the phone to his ear or why he was enjoying the thought of someone hearing how much of a slut he was or at least how much of a slut he was to his best friend he had feelings for and was too fuckign terrified about losing the embodiment of sunshine to say anything.

"I'm sorry," Katsuki blurted out. "For what I said."

Eijirou licked at the mark he left on his neck, Katsuki would have to most likely get concealer or something to hide it tomorrow. He was all too happy for Eijirou to be marking him like that to give a shit.

"Oh," Deku was silent and Katsuki nearly thought he hung up and almost let out a small whimper when Eijirou moved his hand to rub over his clit.

"Uh thanks for uh apologizing and I am really sorry about the muttering I didn't notice and I know you can get overstimulated at those kinds of sounds," Deku finally spoke.

But all Katsuki could focus on was how Eijirou pulled out of him, keeping his legs spread wide as he traveled and kissed down his torso and Katsuki only grunted in response to Deku's rambling.

Too busy noticing how Eijirou's mouth moved lower and lower until he was licking up his pussy. His hot tongue sucking on his clit before going lower. Mouth pressing over him, licking and sucking at his clit and down to his cunt.

Eating him out as if he were a starving man.

"Godsdamnit!" Katsuki cursed, his free hand gripping the sheets.

"What?!" Deku asked, startled.

Katsuki felt his pussy clench around nothing as Eijirou sucked him off. Katsuki could do nothing to stop it, cumming only to have two fingers shoved into his pussy.

Eijirou curled his fingers ever so slightly as he pulled them out before pressing them back in.

Katsuki was going to die.

He just came while on the fucking phone with Deku.

"Are you sure you're okay, you seemed a little red earlier, do you have a fever? Do you want me to get Mr. Aizawa?" Deku rambled on.

Katsuki would be annoyed about the fucking muttering again, talking too much and rambling on about nothing or being a worrying mother hen about everything, but Eijirou was pulling his fingers out of Katsuki's pussy only to press them to his mouth.

He was gone.

Katsuki opened his mouth, sucking on the two fingers as if they were Eijirou's cock. Licking it clean from his own mess. Like the good little bitch he could be when he wanted to be.

It was short-lived when he made eye contact with Eijirou who was staring intently at his fingers and out lewdly Katsuki was sucking on them. Tasing himself was not new and he loved seeing how glazed over it made Eijirou when he did things the redhead didn't expect.

Eijirou pulled his fingers back, spit-covered, and he pressed them back down between his legs with a devilish smirk.

"No, I'm fine, just tired. I just wanted to say that so—" Katsuki trailed off.

Eijirou was watching him, his dick hard and leaking a bit of pre-cum. Katsuki was pretty sure he zoned out for a moment.

"Kacchan, are you sure? I can bring Recovery Girl up," Deku offered.

It took everything for Katsuki to be nice.

To not tell the fucker off for being all mother hen again or whatever the fuck.

But he didn't have the time or the attention to focus on it too much before Eijirou was settling between his thighs again and slamming back into him. This time not caring if Deku heard over the phone. Eijirou fucked him just the fucking way Katsuki wanted.

Rough and shameless.

His balls clapped his ass as he slammed into him with each thrust, arms caging him in and Katsuki was pretty sure he moaned at some point. It was lewd and impossible to miss as he dropped the phone on the bed.

He arched his back as Eijirou pounded into him.

"Come on, Tsuki~" Eijirou whined. "Pick up the phone and say bye," he whispered.

Katsuki gulped, he was out of breath and unable to hide what he was doing. He felt the sheets for the phone that was very much still connected as he shakily held it back up to his ear.

"I—have to go," Katsuki stammered out.

He let out a silent scream as Eijirou slammed right into his g spot. Katsuki was damn near seeing stars with how good it felt.

Katsuki hoped his voice wasn't as breathless as he felt.

"I have to go to bed. Bye."

"Kacchan—"

He hung up.

Eijirou was too caught up in the moment to notice the phone being flung across the room—and Katsuki too focused on the relief of the phone call to notice he failed to hang up the phone and that it was still very much connected to the call still.

Katsuki moaned. "AHH—fuck—fuck!"

Eijirou laughed at him.

"Do you wanna cum Tsuki?"

Katsuki whined, nodding his head as he desperately tried to not get totally lost in the fuzzy feeling clouding his thoughts.

"Please, please!"

"I'll tell you want," Eijirou paused his movements clearly.

Katsuki felt himself let out a cry, his eyes blurred as he looked up at Eijirou.

He fucking needed to cum.

He needs Eijirou to fill him.

Fuck him.

Feel the release of cum on him.

In him.

Katsuki needed it.

Gods, he needed it.

Eijirou snapped his fingers in front of his face.

"Back with me?"

Katsuki nodded.

"You get to cum only if you make breakfast for everyone tomorrow without a single godsdamn complaint about it," Eijirou leaned into his neck again.

Sharp teeth biting into his shoulder.

Katsuki yelped. "Yes, fuck. Whatever you want, just let me cum!"

He tried to move their hips but Eijirou didn't budge, only forcing him to look up at him. A look on his face that Katsuki could probably try and understand if he wasn't feeling so cock drunk.

Katsuki's eyes rolled back when Eijirou fucked into him again, thrusting into him so hard Katsuki had to hold onto the headboard behind him just so his head didn't keep hitting the damn thing.

"Yes, yes—oh gods—yes!" Katsuki screamed. "Fill me please, just fill me please!"

"As you wish Tsuki," Eijirou moaned.

He thrust into his g spot one more time and Katsuki only saw white as he came around Eijirou's cock. The familiar warmth of Eijirou stilling in him and Katsuki moaned at the feeling of him cumming in him.

Deep.

Katsuki had never felt so fucking blissed out.

He was out of breath.

He felt boneless, totally relaxed.

Slowly the realization sank in, like it always did. There was always a part of him that felt like shit afterward. Eijirou only saw him as a friend.

Not the realization Katsuki liked to make when he had his best friends jizz in his pussy but fuck Katsuki couldn't help it. He fucking loved the few seconds of bliss. When Eijirou let go, grabbed him tight, when he kissed his neck, when he stilled in him for a moment before he came.

He had time to pull out.

But he never did.

Something that would have been concerning if Katsuki hadn't demanded on a copper IUD after working out his testosterone. It would have to work for the time being, at least until he made the visit to the doctor to remove his whole damn uterus.

For right now this was just what had to work.

"Such a good brat for me, huh?"

Katsuki nodded. "Yes."

Eijirou leaned down and kissed him, parting his mouth as he lazily kissed him back. Katsuki hummed at the feeling. He could pretend in these soft moments, pretend there was something more.

He relaxed again.

Eijirou pulled back only to kiss him again this time on the forehead before laying back on the bed, pulling out in the process. Katsuki let himself be wrapped into his warm hold, ignoring the mess between his legs as he settled in.

Eijirou cuddled closer using him as nothing more than a pillow.

Katsuki closed his eyes, he would get up early and keep his promise before anyone woke up. He could make breakfast and then get a much-needed shower.

Katsuki got out of bed throwing a pillow at Eijirou to hold onto instead. The red-haired man happily nuzzled into it, sleeping as if he hadn't just railed Katsuki last night.

Katsuki rolled his eyes at his best friend and stole the himbo's hoodie. Throwing on a clean pair of joggers. Ignoring how much his back hurt and how he could still fill the load of cum in him.

He groaned before sliding on his slippers as he grabbed one of the small bottles from the mini fidge and drinking one of his homemade greenjusices before heading downstairs.

It was early.

He had the kitchen to himself as he got everything he needed out and sat on the counter.

He had the prep time done by the time people started waking up. He put his hood up and ignored them as he worked.

He wanted to go back to bed.

Get a few more hours of sleep and ignore his best friend who talked in his sleep. Mostly gibberish and manly bullshit but fuck, Katsuki thought it was adorable.

"Bakubabe," Mina cried out. "Are you cooking? Enough for us?!"

Katsuki didn't bother looking up. He saw out of the corner of his eye that Deku paused in the doorway.

Face red and Mina looking over confused and worried.

"Holy shit he wasn't joking," Deku muttered.

Katsuki raised a brow at him but left it to go he didn't have time for this.

He finished up breakfast. Making a full-on spread of American breakfast foods most of his class loved waffles, pancakes, eggs, and toast. It was mostly all the american style breakfast food Icy Hot usually requested on the weekends when asked what anyone wanted.

Katsuki shoved Mina out of the doorway when he was done but she was not about to let him go that easily.

"Aw, you do care!" she cheered.

And all that Katsuki could think of saying was: 'Yeah, about dick. Hence how I was bribed into doing this,' but he kept his comment to himself.

There was not a single non-horny thought about any of this. He ignored her and the mutterings that made him grip the plate in his hand a bit harder.

He dished him and Eijirou enough before his classmates in healed all of the food that should have been enough for everyone to have seconds but apparently, they all had bottomless stomachs when Katsuki cooked.

And went to leave again but looked at the worrying Deku staring at him still.

"No one will ever believe you," Katsuki winked.

He was pretty sure he ended the call but thinking back on it Eijirou was distracting him. His hands were sweaty so he was also sure Deku ended up hearing a bit more than he wanted him to.

Katsuki shrugged.

He would worry about it when he wasn't so tired.

He walked back to his room, letting himself in. Eijirou was still asleep when he made it back, the room dark as Katsuki set their plates on his desk.

He pulled the covers off his best friend and smirked. Eijirou was lying on his back, still very much naked, and a part of him was all too happy to see him.

Katsuki leaned down.

Slowly settling between his thighs and licking a fat strip up his half-hard cock. If he had to make everyone breakfast before he even got his own then he was going to make it worth it.

He took Eijirou's cock into his warm mouth. Working him over the edge with processed ease, lapping at the head before swallowing him whole. Getting him perfectly hard for him in a new record.

Katsuki got lost in the feeling only to find out Eijirou woke up at some point just in time as he came down Katsuki's throat.

"Fuck sake's, Katsuki," Eijirou moaned.

Katsuki swallowed and smirked at the redhead. He crawled back up enough to straddle his lap but made sure not to overstimulate him.

He looked down at his best friend and knew he was fucked.

It was early, he was tired, and he was too relaxed from last night to realize the words that spilled out of his mouth before he could stop them.

"You're my boyfriend, now."

Not even a question, a statement.

Eijirou blinked.

Whether it be from his just waking up or just waking up and coming down Katsuki's throat only for the blond to tell him they were now boyfriends.

"Say it again."

Katsuki looked back, wide-eyed before he demanded to compose himself.

"Kirishima Eijirou, you are my boyfriend."

Eijirou grinned and before Katsuki knew it he was being pushed off him only to be pinned to the bed. A very happy Eijirou kissed him.

And maybe Katsuki was happy for his lack of a filter, at least when it ended with his boyfriend making out with him.

Did everyone find out by the time the two were presentable again, yes. And really, Mr. Aizawa did not get paid enough to have to lecture his students on their sex lives or having to tell them to keep it down for such events.

But Katsuki was too happy to give a shit. Eijirou was his boyfriend so maybe his luck wasn't as shitty as he thought.

THE END
