Work Text:
Kirishima wasn't the type to have a bad mood, but his day had just been too long. He hadn't seen Bakugou the whole day and his work study had been exhausting. It really had been a long day and he just wanted to relax, maybe let off some steam, so when Mina asked him if he would come to that one party he hesitated, but didn't question it further. He should have.
Half an hour later he stood in front of some high fashioned mansion, regretting his choice.
“Oh come on I thought you were over it by now, you're never that resentful”, Mina tried.
Kirishima just scoffed, glaring up at the house, “It's fucking Monoma, I doubt I'll ever be able to ignore that fucking asshole”.
“Just please promise not to punch him this time?”, Mina looked at him all wide-eyed, her puppy eyes not working on Kirishima.
“I'll fucking try”, he scoffed.
He could hear a snicker behind him. “You know I fucking love it when you swear, Red”, he turned around, successfully catching Bakugou, who had thrown himself at the redhead and was now determinedly smashing his face in his pecs.
“Missed ya”, he mumbled, still hidden in Kirishima's shirt. Kirishima in return hid his face in the blond spikes, enjoying the smell of caramel and smoke surrounding the blond. He kissed the top of his head and held Bakugou close around the waist, relaxing just for a moment.
And then holding him at arms length.
“Damn, I'm lucky”, Kirishima sighed. Bakugou smirked. The shirt he was wearing was one of Kirishima's tank tops, loose on his more slender form and shorts.
Short shorts.
Ass almost hanging out short shorts.
Kiri's hand twitched. He wanted to grab.
“What took you so long?”, Mina hissed at Kaminari trotting over to her.
“He refused to come along until I said that Kiri would be here and it would be at Monoma's, don't know why though. And then he took like half an hour to get ready”, he shrugged.
They started towards the door, making sure the other two followed them. Kirishima grumbled, but reluctantly followed Bakugou up the few stairs, enjoying the view.
The door was open, inviting in to a large foyer, filled with people around their age, holding a variety of alcohol.
“Sero!”, Kaminari exclaimed, waving exaggeratedly at the tall boy across the room. They made their way over, interrupting his previous conversation with Uraraka.
“Hey, what's the hold up? I only had like Jirou and Todoroki to talk to”, he complained, leading them to the kitchen. “No offence”, he nodded at Uraraka who shrugged.
“Someone-,” Kaminari glared at Bakugou, “was being difficult”
Bakugou rolled his eyes and glared back, Kirishima's arm around his shoulder obviously calming him down to an almost social level. Otherwise there would have been much more insults and screaming involved by now.
“And I had a long day, you know the work studies”, Kirishima sighed, reaching out for a beer Sero was offering out the fridge. The drink was pleasantly cold in his hand. He really needed it right now.
They clinked their bottles together and each took a sip of their first, but certainly not last drink today.
“There's a dance floor the hall down and a smoker's nook out back”, Sero told them, “I've already seen like most of class B and some of us-”
“Yeah yeah, where is the beer pong, I think we need to catch up”, Kaminari declared, already leaving in some direction and the rest just following, until Sero pointed out the assigned room to them.
It was another big room, with some couches, a pool table and two tables where between others the Dekusquad was playing.
Right now Todoroki was throwing, obviously already tipsy, but somehow he shot the ball perfectly into the last cup, their opponents groaning and one of them reaching over to grab the last four of the Dekusquad's cups.
“Fuck yeah, we're gonna destroy fucking Deku, come on”, Bakugou dragged Kirishima by his hand, the redhead happily following along.
Deku groaned when he saw Bakugou strutting across the room.
“One game”, he said, “and not one more. You now what happens otherwise”
They all knew what happened otherwise. And as cute as Bakugou could get when drunk, aggressive drunk Bakugou was not fun. One beer pong tournament between the two of them had ended in three broken tables and some more collateral damage. In the end it had taken both half drunk squads to get the two of them apart. They shuddered unanimously at the memory.
The game was rebuild, the cups filled and first ping pong balls going to Bakugou and Deku. Kirishima could see Bakugou's sharp jaw clenching. Deku was beginning, by whatever rule Iida had recited. He glanced at Bakugou and took place, staring at their triangle of cups. He threw, and missed.
Bakugou besides Kirishima snorted. It was his turn. He was glaring excessively first at Deku, then aimed. He missed, too and Kirishima had to hold him back from flipping the table.
After that, the competitiveness just rose and quickly both teams were down to their last cup. Bakugou was seething, glaring at the ball he was holding. He hadn't hit any of the cups, anger obviously getting the better of him.
“Let me”, Kirishima whispered in his ear, leaning close. He reached over and took the ball quick enough that Bakugou couldn't close his fist around it. He winked and Bakugou glared, ears tinted pink. Kirishima took position and aimed. He took a deep breath and threw. And hit the target perfectly.
“Fuck yeah”, Bakugou bumped in his shoulder, grinning widely. Kiri rolled his eyes, still pulling Bakugou in by his waist.
“Just for you”, he whispered while the others still cheered. He could feel Bakugou shiver in his hold.
“Come on, spectacle's over, I wanna go dance”, Mina said and Kaminari's face lit up, and they started leaving.
“Wanna join them? Or do you need another drink for that”, Kirishima breathed into Bakugou's ear, still wrapped around the smaller man.
“Let's get some shots, yeah?”, he mumbled back, twisting in Kirishima's grip and facing him. They both knew that Bakugou could dance, but only if enough alcohol had flown beforehand.
“Was that shots I heard?”, Sero apparently hadn't left with the other two, instead joining them on their way to the kitchen, pulling Todoroki behind him.
They played a game, spinning a small bottle in a circle of shots and a big bottle in their circle and the chosen one had to take the designated shot. They didn't play more than one round. Their circle of shots had been 'too many' apparently.
But enough to get Bakugou drunk enough for the dance floor, simultaneously sending poor Todoroki on one of the couches, feeling nauseous.
The dance floor was packed, the bass making the sticky floor vibrate, people dancing and grinding everywhere. Somehow they found Mina and Kaminari dancing with that purple guy from class B. Kirishima couldn't remember his name.
They sweat through the next few hours, limbs and bodies shaking. Somewhen Kaminari started dancing very close with the dude from class B and Mina had collected Uraraka on a drinking pause, the two of them moving in their own world.
And Kirishima himself was very focused on how the blond in front of him moved, his hips shaking, arms twisting and rising, now coming back down behind Kirishima's neck. Bakugou was close. So close, red eyes fixed on him, even in the dim light. So close
“Brooo”, a loud voice interrupted their moment, bumping into Kirishima's shoulder and wrapping a large arm around his shoulder. Tetsutetsu.
“Wasssupp”, he slurred, slightly tipsy, but still putting most of his weight on Kirishima, who was not in the very least annoyed and did not roll his eyes. Bakugou giggled tipsily. Kirishima had to smile lopsidedly at the cute action.
“Where's Kendou?”, he shouted at the metalhead, trying to talk over the loud music.
“Somewhere-”, he raised his arm from Kirishima's shoulder, “-I think – no she went to the kitchen”.
Kirishima nodded his head. He could feel the soberness creeping in on him.
“Want me to help you find her? I need another drink”, he asked if Bakugou wanted to join, receiving a positive answer.
The three of them fought through the thick crowd over to the kitchen.
When they arrived at the main bar thingy, Kirishima started mixing himself a drink, hearing Tetsutetsu talking about his gym routine at Bakugou.
“T!”, a loud voice got through the quieter music. Kendou.
“Bakugou! Yo”, another voice. Unrecognisable to Kirishima.
“Ugh, some fucking extra form middle school, M'gonna talk to him and tell him to fuck off”, Bakugou squeezed his hand not holding a drink and went a few metres away, grunting at some tall guy.
Kirishima just stood there for a moment, enjoying the buzz around and inside him, the chatter and the laughter, the world slightly tilting every now and then. He stole another glance at Bakugou's illegal shorts. His legs looked really great. They would look better over Kirishima's shoulders. He licked his lips and took another sip from his drink. A nice thought for later maybe. If they weren't too drunk and/or exhausted. He sighed and took another sip.
“If it isn't the rock head from class A”. Kirishima tensed up at the annoying voice, obviously directed at him. He turned. Fucking Monoma. He had to hold back another eye roll. It was his party after all.
“Where's your little squad eh? Or your little explosive bodyguard eh? I thought I saw his ass flouncing around here somewhere”, Kirishima snarled. Outside class A almost nobody knew of his and Bakugou's relationship, but their closeness wasn't missed often. And he could barely hold himself back at the arrogant asshole as long as he didn't bring up his friends or Bakugou, let alone Bakugou's ass.
“What do you want Monoma?”, he asked, as calmly as he could muster up right now. He frowned at him, unconsciously glancing over to where Bakugou was still talking to that guy.
“Oh right, there he is”, Monoma followed his eyes, grinning evilly, “well he seems to be occupied.” Kirishima was glaring at Monoma, so much that he could see how his eyes stared Bakugou up and down. Kirishima had to hold back a growl. How dare he look at Bakugou like that. He clenched his hand harder around his drink.
“So that outfit right?”, he raised an eyebrow, “certainly attracts attention eh? I mean we all know he needs it. Just look how he gloats at some guy giving him an ounce of attention. Have you been slacking off?”, he chuckled. Kirishima did growl this time, which did not stop Monoma the slightest. Bakugou knew he was Kirishima's. He was his.
Monoma dared grinning even wider, looking at Kirishima down his nose, his grey eyes swirling.
“Think he'll loose the shirt if I pay enough?”
Crack. Kirishima's fist connected with Monoma's face. Without a glance back, he crossed the room pulling Bakugou by his arm to some secluded corner. Bakugou was his. Bakugou knew that.
And Bakugou smirked. Every fucking time. Somehow every time Monoma had some conversation with Kirishima, he was guaranteed a damn good make out session if not more and a neck full of hickeys.
As it surely would be soon enough.
He had seen Kirishima break people's noses before, hell even Monoma's nose, but the look he had send him directly afterwards was new. And damn was it hot. He looked … almost angry. And Bakugou did not resist one second to being dragged away from the boring conversation he had.
Fuck he was hot when his eyes shone with thinly concealed anger like that, his usually sunshine boyfriend nowhere to be seen.
He was being pushed against the wall, a warm hand protecting his head, before hot lips were smashed against his, Kirishima's mouth demanding and pushing. Bakugou knees buckled at the display, quickly saved by a thick thigh pushing between his. He moaned into their kiss, Kirishima not missing his chance and sneaking his tongue into his opened mouth. He hadn't noticed Kirishima's other hand, which was now making it's way teasingly up the stolen top, pulling him closer by the waist and creating much needed friction.
Kirishima released him from the kiss, just to hear the sweet moan falling from the blonds lips. He growled, goddamn growled, and if Bakugou wasn't already completely gone, this would have been the moment to go fully putty in Kirishima's large hands. His head was being pulled back by his hair, eliciting another noise from Bakugou. There were a few kisses placed on his neck before the first bite. Bakugou rolled his hips at the sharp pain melting into pleasure.
There was a small pause, Kirishima staring at the quickly forming hickey. He breathed at Bakugou's ear.
“Tell me-”, he rasped, voice at least an octave lower than normally, ”-tell me who you belong to”
Bakugou was barely in the mindset to mutter, “you. 'M all yours”, before gasping at another sharp bite to his collarbone.
“Let's get out of here”, Kirishima growled, not moving an inch. He was the only one who got the see Bakugou like this, walls down, blush high on his cheeks, hickeys blooming on his neck and shorts certainly tighter than before. He pulled him close, resting his hand in one of the blond's back pockets as they quickly made their way to the door.
Bakugou spared one last glance at the kitchen revealing Kendou scolding Monoma who was holding a tissue to his nose, before the hand on his ass pulled him forward.
“All mine”, Kirishima whispered a few hours later, drawing shapes on Bakugou's bare back.
“All yours”, he sleepily smiled back, almost passed out in Kirishima's arms. He was shifting every now and then, revealing hickeys and lovebites to what little moonlight passed through Kirishima's window.
The Aftermaths:
“Good morning y'all”, a cheery loud voice shouted.
“How can you have like absolutely no hangover? You drank more than I did”, Mina groaned, not even lifting her head form the table.
“Good karma I guess”, Kaminari shrugged, plopping down next to her and serving himself some of the food.
“Yoo what happened to you”, he stared at Bakugou's neck. Then he gasped. “Have you been attacked by an opossum on your way back? There is this guy training opossums to attack random people on-”
“What the fuck dunce face? An opossum? Fuck right off with that shit”, Bakugou yelled, blushing nonetheless and trying to pull his shirt higher over his neck. He would have to stop stealing Kirishima's shirts if he continued to leave this many marks. Not that he really minded them. It was kinda hot, some of the marks staying for days after.
He shovelled the last of his food into his mouth and slammed his dishes in the dishwasher, quickly making his way back to the elevator. Kirishima was still sleeping upstairs, maybe he could get some more cuddles before the day really had to begin.
“Yeah sure get back to your opossum”, Mina grinned at him. He flipped her off while the doors were closing
He did get some more sleepy cuddles.
