Chapter Text
“You’re drooling, Eiji.”
Kirishima blinked, a spoonful of curry frozen halfway to his mouth. Across the training dorm’s kitchen, Mina stood with her hips cocked, one brow raised, and a devilish smirk curving her lips.
“I—what? I’m not!” he said way too fast.
She sauntered over, hips swaying like she knew exactly what she was doing. Her new workout crop top clung to her just enough to be dangerous, her pink skin gleaming from the post-gym glow. “Mmhmm. You’ve been staring at me for the past five minutes. I counted.”
“I wasn’t staring,” he said, turning redder than his hair. “I was—uh, zoning out!”
“On my butt?” she teased, leaning in and stealing the spoon right out of his hand. “That’s new.”
“Mina!” he hissed, ears burning. “You can’t just say stuff like that!”
“Why not?” She licked a bit of curry off the spoon, her eyes locked onto his like it was a challenge. “You’re always so good, Eiji. So polite. It’s cute.” She leaned closer. “But I wonder what it’d take to make you not so polite.”
His breath caught. “You’re playing a dangerous game, Ashido.”
“Oh?” she giggled, backing away slowly. “Is Red Riot gonna teach me a lesson?”
She winked—and that was it.
He stood so fast the chair scraped the floor, and in three strides he had her backed up against the fridge. Not touching. Not yet. Just close enough for the heat to crackle between them.
Her smile faltered for just a second. “You gonna kiss me, tough guy?”
“Only if you ask nicely,” he murmured, voice low.
Her breath hitched—but her grin came back full force. “Please.”
And he did. Firm, hot, full of all that pent-up tension she’d been playing with for months. Her hands tangled in his hair, and he lifted her like she weighed nothing, setting her on the counter without breaking contact.
When they finally broke apart, breathless and grinning, she poked his chest. “Took you long enough.”
“Maybe I was just waiting for you to get really cocky.”
“Oh, baby,” she said, looping her arms around his neck. “You have no idea how cocky I can get.”
“Oh, I’ve got a pretty good idea now,” he said, leaning in again, voice low, gravelly. “You’ve been driving me crazy for months, y’know that?”
She tilted her head, playful and smug. “That’s half the fun.”
“I figured,” he murmured, brushing his nose against hers. “But here’s the thing, Pinky… you’re not the only one who can tease.”
Mina opened her mouth to respond—probably with some spicy comeback—but before she could, he trailed a hand up her thigh. Not rushed. Just a slow, calloused drag up the outside of her leg, making her breath stutter in her throat.
She narrowed her eyes. “Oh? Is this you trying to be smooth?”
Kirishima grinned, all sharp teeth and confidence. “Nah. This is.”
He leaned in, lips grazing the shell of her ear. “You keep looking at me like that and I’m gonna forget we’re still in the common room.”
Her thighs instinctively tightened around his hips, and she swore under her breath. “You wouldn’t.”
“I would. And I think,” he said, voice dipping low as his hands settled at her waist, “you want me to.”
Mina’s heart pounded like a bass drum in her chest. Sure, she teased him constantly—he was hot, he was fun, and seeing him flustered was addictive—but this was new. This was intentional. He wasn’t flustered now.
He was focused.
“Okay, Red Riot,” she challenged, voice a little breathier than she meant. “Show me what you’ve got.”
His eyes burned with something darker than usual, but he still chuckled. “You’re not scared of poking bears, huh?”
“Not when the bear looks like you.”
“You’re such a little menace.”
She leaned forward, brushing her lips along his jaw. “You love it.”
“Yeah,” he breathed. “I do.”
The second kiss was different. Slower. Hungrier. His hands pressed into her hips, grounding himself like she was the only solid thing in the world. Her fingers slid beneath the fabric of his shirt, tracing over his scarred abs with a curious reverence that made his stomach tense.
When they finally broke apart again, both of them dazed and flushed, Mina let out a soft laugh. “Okay. Maybe I’ve underestimated you.”
“Glad we cleared that up,” Kirishima said, voice rough. “But hey…”
“Hm?”
He looked up at her, eyes softer now—sincere beneath the heat. “This isn’t just messing around for me. You know that, right?”
Her smirk faltered—just slightly. “Yeah. I know.”
He brushed her cheek with his thumb. “So if I take this seriously… if we do… you’re all in?”
Mina looked at him—really looked—and for a moment, she didn’t joke. Didn’t tease. Just nodded.
“Yeah,” she whispered. “All in.”
And just like that, the heat between them settled into something deeper—something steadier than fire.
The dorm kitchen was quiet—too quiet, given what was happening inside it.
Mina’s legs were still wrapped around Kirishima’s waist, her fingers tangled in his shirt, lips just barely parted from their last, toe-curling kiss. His hand was cupped around the back of her neck, thumb brushing that spot just below her ear that made her squirm.
And then—
SLAM.
The door burst open with the full force of a dramatic anime entrance, and in walked Denki Kaminari, earbuds in, head bopping to whatever ridiculous playlist he’d made this week.
“Yo, Eiji, I was thinking we could hit the gym and do some—”
He froze. Mid-step. Mid-bop. His eyes landed on Mina sitting on the counter, Kirishima standing between her legs, both of them still very much entangled.
“…deadlifts,” Kaminari finished weakly, blinking.
Mina blinked back. Kirishima didn’t even move.
Kaminari’s mouth slowly stretched into a grin. “Oh. OH. So that’s why you skipped leg day!”
Mina choked on a laugh and buried her face in Kirishima’s shoulder.
Kirishima groaned. “Kaminari, I swear to god…”
But it was too late. Kaminari was already backing out of the room like he’d just discovered forbidden knowledge. “I didn’t see anything! Nope! Just two friends… practicing CPR… on a counter…”
He was gone before either of them could recover.
Mina finally pulled her face out of Kirishima’s neck, laughing so hard her eyes watered. “You should’ve seen your face.”
“You’re lucky I like you,” he muttered, cheeks on fire.
“Oh, come on,” she grinned. “That was bound to happen eventually. You really thought we’d get away with this in this dorm?”
“I was hoping.”
Before they could even step away from each other, the door creaked open again.
This time it was Yaoyorozu, looking polished and composed as ever—until she saw the scene in front of her.
Her eyes went wide. “Oh! I—I’m sorry! I didn’t mean to interrupt anything, I just needed to grab the tea kettle—!”
Mina raised a hand lazily from her throne atop the kitchen counter. “Hey, Momo. We were just… testing gravity.”
Momo blinked. Once. Twice. “I see.”
“I don’t see!” Sero called from the hallway. “Why is Kaminari giggling like a maniac on the stairs?”
Kirishima sighed and let his forehead drop against Mina’s chest. “We’re never gonna live this down.”
“You’re the one who said stay here a little longer,” she teased, ruffling his hair. “Guess we’re in it now.”
From outside, Kaminari’s voice rang out “I’m calling it now—power couple of the year!”
“They were making out in the kitchen, weren’t they?”
Sero quipped.
Mina cupped her hands around her mouth. “We’re not sorry!”
Kirishima groaned again. “I kinda am.”
“No, you’re not,” she said, leaning in and kissing his cheek. “You love the chaos.”
“…Maybe a little.”
