Work Text:
It's not often that you're invited to the same parties your brother attends. And truth be told, you're probably not supposed to be at a third-year party when you've just barely made a name in your first sports festival. You're pretty sure you had to work double-time to make up for the impressions Katsuki has left on people, both in classes and out of them.
Denki had been the one inviting you, smiling from one ear to the other, like he knew a great joke he wouldn't quite tell you.
"And bring your friends," he said. "Especially the redhead who's got a crush on Midoriya."
"Eh?" You blinked. "Why's that? Denki? Are you planning something?"
"Maybe," he pinched your cheek. "And if you've got a fat little crush on someone in third year, this is your chance."
"You can't have a crush that's both fat and little," Masako pointed out on your left, pushing her glasses up her nose. "But, uh, is Iida-san going to be there as well?"
-
You lose your friends right as you enter the dorms of the third-years, Masako disappearing like she's trained to do, with her chameleon-quirk and her fable for sniffing out her favorite hero in the world, and Akiko trips over her shoelaces and falls face-first into Midoriya's lap, who feels so guilty that he takes Denki's joke about better visiting the infirmary at face value.
So, that leaves you alone amidst a mass of third-years, some of them looking down at you in curiosity or disdain. You're pretty sure Katsuki doesn't know you're here, so you keep an eye out for his familiar head of hair and the smell of his explosions, and accept the drink that's being pushed into your hands. It tastes awful, so you dump the rest of it into one of the flower pots and march off, determined to find someone worth talking to.
-
Kirishima isn't that hard to spot either, not with his body being the size of a fridge, or his spiky red hair, someone - probably Denki - had decorated with colorful tinsel. You approach him warily, still an eye out for your brother.
"HEY!" Kirishima beams at your sight, and your heart leaps in your chest like an annoying frog. "I didn't know you were coming! Wait!" He grabs you by the shoulders and looks around. "Are you the surprise Denki talked about?"
"I don't know, but he invited me."
"Awesome!" Kirishima's hold is firm and warm, and he's not letting go.
"Uh, do you have something to drink?" You ask, curious about his demeanor.
"Ah, well," he chuckles. "I think Mineta made the punch, and there's not much else in the kitchen that's drinkable, I think. Katsuki is out to get some things because he can't stand low-quality drinks. His words, not mine."
"Shouldn't he have thought of that before the party?"
"Rumor has it there was enough stuff around, but Mineta used it for the punch," Kirishima grimaces. "I haven't seen him around in a while, so he might have gotten punished for his carelessness already."
You laugh, the sound a little tighter around the edges. Your heart's beating double time in your chest from how close Kirishima still is. Does this mean anything? Or is he already a little tipsy?
A commotion down the hallway alerts you, and you try to turn to look for it - it could be Katsuki, after all - when someone bumps into you from behind, forcing you forward. You open your mouth to protest, when it brushes against Kirishima's in the worst possible way, a kiss that's not a kiss, but still... well, a kiss.
You jump back, unable to miss the way his eyes have turned the size of dinner plates, when the bumper behind you seems to have realized something.
"YO!" Smaller hands grip your shoulders, where Kirishima's hands have been seconds before. "You made it. Come, play with us!"
"Don't!" Kirishima interjects, stepping closer. "Kaminari-"
"Why not?" Kaminari puts his head on your shoulder, pouting. You can barely see him, with being unable to turn your head and all, but you know his pout by sound alone. "Worried she'd kiss someone else?"
"Who's kissing who?" You ask, confused, breathless, a little panicked. "What are you talking about?"
"Oh, we're playing seven minutes in heaven, and we're a little low on the girls. I was trying to ask your friends, but the redhead is still being tended to by Deku, and your other friend has disappeared."
"She should be somewhere close to Iida-"
"Yeah, I figured, but Iida's not supposed to know we're playing that game-"
"And you shouldn't play, anyway," Kirishima decides, a surefire way to get you to agree to playing.
"I'm in, then," you turn. "I don't actually have to do anything for those seven minutes, right? We played it during training camp, and we just talked."
"Booh," Kaminari shrugs. "But of course, you can. I'll make sure you don't pull Mineta."
"Pull me," Kirishima breathes out, flushing bright red when you both turn to look at him. "I mean, we can talk. And you won't get Mineta."
"I thought I wasn't supposed to play?"
"Well," he shrugs helplessly. "I guess it's the best hiding place in case Katsuki returns."
"Can't argue with that."
-
Kirishima is even more distracting in the quiet darkness of the broom closet, the ruckus of the party shut out for the moment.
His bicep is pressed against yours, and you can feel it tensing from time to time, as he seems to be thinking.
"I thought we'd be talking," you mumble after an eternity has passed. "We're not talking."
"I'm, uh," he hesitates. "I'm sorry I kissed you."
Your heart sinks. "Oh. Yeah. Okay."
"Not that I didn't want to kiss you," he admits, and heat radiates off him like he's been set on fire, the same heat that's rising to your own face now. "But I wanted to do it properly. With consent!"
"Oh," you breathe, swallowing tickly. "You, uh, got it. My consent, I mean."
Kirishima turns so fast, he miscalculates the distance, pushing you into the wall.
"Sorry," he breathes, "Shit, I'm doing it again. I mean, I-"
You lean in, trying to be brave and suave and, well, kissing him. Your lips hit the corner of his jaw a little awkwardly, and he misses your mouth when he tries to reciprocate, an awkward bumble of limbs and breath and warmth.
You giggle, and he hiccups a laugh, and it's glorious in itself - until the doors are ripped open to reveal your brother, brows furrowed angrily until he spots you.
"There you are," he barks. "You know you're not supposed to be here!"
"I got invited," you bark back, Kirishima turned to stone - literally. "How did you even know where I was?"
Katsuki shrugs. "Someone told me Kirishima's doing seven minutes in heaven. There was no way in hell he'd do it with anyone with you with the way he was looking at you, so-" He turns angry again. "I don't have to explain myself to you. This is a grown-up party, and you're a kid. Get out of that closet."
"Make me."
Katsuki takes one step forward, but Kirishima is a little quicker, grabbing you around the waist and lifting you out of the closet. "We were leaving anyway," he mumbles, Quirk still activated, like he expects Katsuki to blow up any second. "Sorry about that."
"Don't sorry me," Katsuki barks after him. "If you hurt her, I'll blow you up so good, you won't have any Quirk left in you."
"Noted."
