Work Text:

Since they moved to dorms, they were able to spend more time together. It made both of them very happy. Not that Bakugo would admit it. And currently... This stupid happy-go-lucky bastard was supposed to be having sex with him. But no. The higher ups decides, his over-stressed mother has to call right now, when they were almost at the good part. And so... The whole mood was completely ruined. At least for Kirishima. You see... It's just so rare for Bakugo (or anyone) to see Kirishima's annoyed expression. The one he is having right now as he is slowly dressing and trying to tell his mother to finally give him a break. Most people would feel intimidated, scared even by that expression on his face. Especially that eyes. So why the fuck is it that every time Bakugo sees him with that kind of annoyed dark eyes, he gets incredibly hard?! That's it. He needs to leave. And so he also got dressed in record time, grabbed his things and ran out of that room. There is no way Bakugo could live down the shame, if Kirishima saw him getting hard from that.

 

******The next day in school******

The next day, as Bakugo was walking to a school, he heard Kirishima calling after him from behind.

 

"Bakugoooo!!! So sorry about yesterday. Since I moved into the dorm, my mom suddenly became so persistent, she keeps calling me everyday."

 

"It's fine since what happened at Kamino got broadcasted, it's only natural she will be worried about you, right?"

 

"That may be truth but I was impatient since you disappeared so suddenly. Well... I am glad you are not mad at me...Since you even put effort into preparing for me, sorry about tha--"

 

"SHUT UP!! DON'T SAY A WORD!!" A little explosion from tomato red Bakugo could be heard and seen that morning. Till now, Deku has no idea what was that about. But he wishes Kirishima all the luck in this world if he made Kacchan angry...

 

 

This was the first time Bakugo saw that annoyed face so directly.
'Kirishima's always smiling and giggling like an idiot, but he can also be like that to his parents, huh.' Bakugo thought.

 

"What's with that frown on your face, Bakugo?"

 

"Your face is too close, shitty-hair!!" Bakugo was so lost in his thoughts he completely missed the fact that Kirishima stopped talking to Sero and Denki and was standing right next to him.

 

At lunch break, Bakugo made up his mind. He wants... No... He needs to see those eyes again. That annoyed look on Kirishima's face. That's why he started provoking him. But that idiot took it the exactly opposite way...

'Somehow recently, Bakugo is like a little devil!!' Kirishima though.

'He is being mean, but it's somehow... He is so cute. It seems like he has been spoiling me and yet, his aura has been strange... He has been more aggressive even. Isn't he super cute?!!' (Man... You need help.😅)

 

So when Bakugo finally run out of his own ideas, he went looking for the only person who (probably) knows how to annoy Kirishima. That's right. Tetsutetsu from 1-B, Kirishima's best friend. And it did not take long to find him. Seems like Tetsutetsu is on garbage duty today.

 

"Hey, extra. I need to talk with you."

 

"What?! Are you picking fight with me? You wanna go at it?!"

 

"What are you talking about? Are you dump? I just need you to answer my question than you can get out of my sight."

 

"Question? What question?" Tetsutetsu asked. It was really unusual seeing Bakugo seeking help from others, after all.

 

"You are close with Kirishima right? If you were trying to piss him off, what would you do?"

 

""What?"

 

"Are you an idiot? What part of that question did you not get!!"

 

"No. No. I get it. I just... Isn't pissing people off your speciality?"

 

"YOU REALLY WANNA DIE, RIGHT!!"

 

"Bakugo? It really is you. I thought I heard you screaming. Why did you leave class so suddenly. I wanted to have lunch with you. Oh... Tetsutetsu!"

 

"Oh... Kirishima!"

 

"Listen to me, hey!!" Kirishima quickly stood in front of them. Another amazing event this day. Is Bakugo actually trying...?

 

"Kirishima. Why are you here?" Bakugo asked. Annoyance clear in his voice.

 

"Aaah. You see... Big Sis of 1-B found me and told me she saw you two arguing and was afraid you would srar to fight so she send me to find you. It was as hard as I thought. Thanks Bakugo. Hahaha."

 

"You...! Whatever! See you in class."
This left Kirishima and Tetsutetsu really confused.

 

"Well that was... Unusual."

 

"Hmm." Kirishima nodded. It really was. Just what is going on in Bakugo's head. He has been acting really strange since this morning... Kirishima is now on a mission.
'Is it possible that Bakugo has... Has become interested in Tetsutetsu?!' Now Kirishima feels like crying...

 

***|°•‡•°|***|•°†°•|***|°•‡•°|***

 

It was late night, when Kirishima came to Bakugo's room. Well... More like barged really. The next thing Bakugo know, he was lying on his back on his bed with Kirishima hovering over him looking at him with a face of kicked puppy. Bakugo did not know if he should be irritated or intrigued. Did his plan of pissing Kirishima off work?!
"Bakugo..." Kirishima started slowly with tears in his eyes. "have you perhaps become interested in Tetsutetsu?"

 

"Hah?" 'What is this idiot talking about...'

 

"I mean... That is, Tetsutetsu is a good guy, and he is manly, and on top of that, it's shameful but he's a bit taller than be..." Kirishima went on with his mumbling, completely unaware of the dark expression slowly forming on Bakugo's face.

 

'That's not it! This idiot got it all wrong!'

 

"I know I am not that manly, but... I really, really like you Bakugo, so I've... been anxious about it whole day and.."

 

Kirishima cut himself off when he felt strong, warm arms embrace him. Bakugo put his head on Kirishima's shoulder. He really doesn't know what to do with this idiot. And Kirishima couldn't help the blush spreading across his cheeks. Bakugo, after all, never really initiated any intimate touches between them. Well... Sometimes but very, very rarely.

 

"B-B-Bakugo! What are you-!"

 

"We just talked, Kirishima. Nothing of that short. He is your friend, so I just wanted to try to get involved." 'What the hell am I saying?!'

 

"So you... You wanted to become closer to my friends? What the hell... BAKUGO! THAT'S SO CUTE!!"

 

"Stop it, shitty-hair! Don't give me that puppy look!"

 

"Bakugoooo~!! I love you so much!" Not it was Katsuki's the to be tightly embraced by his boyfriend. And suddenly a red blush came to rest on his cheeks no matter how much he tried to fight it down. He failed miserably.

 

"So you are not an idiot after all.... I love you too."

 

*******The next day in school******

 

"Hey, Bakugo!" Bakugo turned around as he was walking to his first class when he heard Tetsutetsu calling him.

 

"What do you want? Make it quick."

 

"What we talked about the other day. Are you trying to do something to Kirishima? I left the issue unsettled at the time but... I can't let you do anything to him. Kirishima's my friend!"

"It's nothing. Forget it." Bakugo turned his back to Tetsutetsu and started walking away, when he felt someone grab his wrist. He looked at Tetsutetsu with his murderous look, daring him to do anything. None of them realising they made it to a chemistry room. (Our beloved chemistry Rosemary... 😓)

 

"I can't let you do that! Kirishima is my friend! If you're up to no good with him, than I can't overlook it!!"

 

"Och! You are just as smothering as shitty-hair, HUU?! LET GO!! NOW!!"

 

"Smothe- I was just curious... So what are you acting so righteous for?!" Tetsutetsu yelled.

 

"What did you just say!!" Bakugo's back hit the rack where all the test-tube's were. They came falling down on both of them. Tetsutetsu realising it was his fault run up to Bakugo, throw him at the floor below him and stood hovering over him with his iron skin, so that no glass or any of the tube contents would fall on Katsuki.

 

"What the hell-?! Get off of me!"

 

"Aaah... Don't move. The shards of glass are-"

 

"I don't need your protection!"

 

Kirishima was walking down the school hall when he heard Bakugo yell.
'Bakugo's voice? And he sounds pissed...' Kirishima decided to follow that voice, hoping he would find his boyfriend and they could spend some time together. What he was not expecting was to find his best friend and his boyfriend, both lying on the ground in the chemistry room. And that in quite damaging position, with Bakugo's shirt tolled up, showing his abs and chest. Tetsutetsu had his knee between Bakugo's legs, keeping them open and his hands were on both sides of Bakugo's head giving him no way to escape. Both of the looked surprised at the Kirishima standing in the door with a dark look on his face.

 

*******************************

 

It all happened so fast, Bakugo's mind was not following. One moment he was in the chemistry room with that iron-headed idiot, and next thing he knows he is roughly thrown onto his bed in his dorm room and Kirishima is kissing the living hell out of him. The kiss lasted for few minutes, before Bakugo really needed to breath some air.

 

"Hey Bakugo... Why were you alone in that position with Tetsutetsu?" Kirishima looked down on him with unclear eyes, filled with anger and lust. His voice was low, lower than usual and it made wonders to Bakugo's lust clouded mind. He can feel himself getting hard with that voice and eyes both focused on him - and him only.

 

"Bakugo. I don't care who you are interested in. Remember..." Kirishima ripped his shirt open with one of his hands. The second one was places next to his head on pillow. Both Kirishima's legs were keeping Katsuki's open. Kirishima moved to Bakugo's neck and littered it in red bite-marks and kiss marks. Bakugo pushed him off and looked him in the face. And there it is. That face... Pissed off. Kirishima is totally pissed off.

 

"If I wasn't there, what would have happened? Hey..."

 

"No. You've got it wrong. T-that was...! Something from the shelf above us just happened to fall down and shitty iron bastard just-"

 

"It's true, Tetsutetsu and I have lot in cammon... And he is manly, huh? I probably can't stop you from what you're interested in but... You need to remember, that the only one who is allowed to touch you, to see you like this... The only one who is allowed to love you is me. And me only! Do you understand me?"

 

'These eyes again... What the hell is wrong with me?' Bakugo thoughtand before his mind could even comprehend what was happening he was once again pinned to the bed with Kirishima kissing him and pinning his hands down with one of his.

 

"It's time for your punishment, Bakugo."

 

"Wait. Kirishima!"

 

"On four."

 

"Wha-"

 

"Now!" With that tone of voice and eyes, Bakugo found himself following the order. Kirishima did a quick work with both of their clothes and slowly started to push on finger in. A few moans escaped Bakugo's lips, as he felt second finger entered him.

 

"Hey Bakugo, have you... been playing with yourself?"

 

"Wha-!! Shut up!" The blush spread from his cheeks to his ears and neck as well.

 

"This place hasn't been played with recently. You didn't do it, right? Fuck- You have this sexy body and yet... You've been neglecting me... So that's why you've been messing around with other guys, huh?" Outraged, Bakugo turned around.

 

"Ah?! What the hell are you saying? You know I wouldn't- Aaah!" He got cut off as he felt something much bigger than fingers push inside of him. A loud moan of pleasure and pain escaped him. It was accompanied by the sound of skin slapping against skin. Kirishima lifted his legs and put them on his shoulders. He bend down and started kissing Katsuki again. Bakugo was bend in half and thanks to this new position, Kirishima could go even deeper inside of him. Kirishima moved his lips from Bakugo's neck, to his pink nipples. He took one of them in his mouth and played with the other one with his fingers. Kirishima's second hand found its way all the way down to Bakugo's manhood. It took only a few strokes of Kirishima's hand for Katsuki to come undone.

 

 

"I just put it in but you already came? Has it become a habit for you to come like a girl, huh Bakugo?"

 

 

"S-shut up! Don't -Aah!- Don't look so smug about it!"

 

"Aaah. But look. This part of you hadn't been used for such a long time and yet, it's sucking me up this much and won't let go." The fingers which were playing with Bakugo's pink nipple softly touched his entrance, as Kirishima slowed down his thrusts and began slowly taking his dick out.

 

"What do you thing you are doing. Don't touch-!! Aaaaah." A scream was ripped out of Bakugo's throat when Kirishima suddenly pushed all the way in without warning.

 

"You don't understand it, do you? Just how cute you are like this..."

 

"What the hell are you- Ah! Kiri-Ah-Shi--Ma!!"

 

"Did you come a little again? You're coming easily today, huh? When I saw you got pushed down by Tetsutetsu... I thought I was going crazy with jealousy. Hey... Can you call me by my name? 'Cause you belong... To... Me... Be more aware of that!!"

 

"Aaah! Kiri- Ah! Eijiro! Wait a-AH!- a minute!"
'He is not the same as usual. Not the usual hesitant movements. What- He is fucking me however he wants. It's so- So good!' Bakugo thought as Kirishima picked up his pace again. His thrusts were strong and quick. His hips slapping against Bakugo's ass, as his dick went even deeper inside that hot and soft hole, hitting Bakugo's prostate more directly.

 

 

"Can anyone other than me satisfy you like this?! Your shape, your body has already become exclusive to me!"

 

"Seriously. Eijiro! Stop! It hurts! I-I think I'm coming! Sto-Aaah!"

 

"You leak when I push here. Your insides are so willing... Let's come together, okay?" After a few more thrusts they both came. Bakugo on their stomachs and Kirishima inside of him.

 

"I love you, Bakugo."

 

"Of course you do!... I love you too..." Bakugo whispered after they came down from their bliss.





"DON'T GET HARD AGAIN! IDIOT!"

 

"I'm sorry. One more round!"

 

"What?! No way. Get los-Aaah! Don't push in!"

 

"I love you."
