Kirishima pinned his girlfriend to the bathroom door, turning the lock. He gripped her hips tightly, and leaned towards her.

"Babe, we're gonna have to be quiet, okay? We don't want your parents hearing us having fun."

His lips were pressed lightly to her ear, whispering proactively. Y/n shuddered, biting her lip.

"Of course, Eji. This is our alone time."

She cupped his face in her hands, dragging it towards her own. Their lips met, in a slow passionate kiss.

Kirishima slid his hands down, cupping Y/n's ass. She smirked against his lips, grinding her hips into his. He groaned into her mouth, keeping as quiet as possible, and she repeated her actions. The redhead moved his hips in sync with hers, slipping his tongue into her mouth. She tangled her fingers in his hair and pulled him closer. He moaned at the feeling, bringing his hands up to her stomach.

"You have such an effect on me."

"Same here."

Y/n felt his arousal poke her thigh, and a mischievous glint appeared in her eyes. She ran one hand down his abdomen, her fingertips brushing the bulge in his crotch. His breath hitched, and he broke away from his girlfriend.

"We shouldn't. Not here."

"I guess you're right, everyone's probably wondering why we're in here."

She moved to hug her boyfriend, but he held his hand up in front of him, signalling for her to stop.

"Can I have a minute? To s-sort...this out."

He gestured to his hard on, smiling nervously. Y/n nodded, understanding his awkwardness.

"Yeah, I'll go wait for you in my room. Try to be quiet though."

She blew a flirty kiss at him, turned on her heel, and left the bathroom.

"Hey, Katsuki, we're watching a movie in the living room. Wanna join?"

"Fine. But ONLY because someone needs to keep that pervert's hands off of you, and Mom refuses to do it."

"Okay, Katsuki. Just come downstairs."

Y/n pushed off of the wall, walking out of her brother's room. He followed her, complaining about her speed. They entered the living room, seeing their red haired companion getting comfortable on the couch. Y/n joined him and, just as he was about to throw an arm around her, Katsuki placed himself in between them, pushing the couple away from each other.

"There is no fucking way I'm letting you two get all cuddly and shit. You're gonna sit as far away from each other as possible, and I'm gonna make sure there's no funny business."

Y/n huffed, giving him the finger, and pulled her blanket over her completely. Kirishima sighed, knowing Katsuki wouldn't let them near each other, and looked at his girlfriend, sadly. He was looking forward to cuddling Y/n all night, but she was his bro's sister, and he would have to respect that. He glanced at her, smiling when they made eye contact.

She smiled back, forgetting the movie playing in front of her. Kirishima did the same, just admiring his love.

"Oi, stop staring at her, dumbass."

"Sorry, bro."

Y/n kicked Katsuki's leg, receiving an angry grunt in return, before locking eyes with Kirishima again.

"Come sit here, Eji. You're so far away."

"Um, I'm not sure I sh-"

"Fuck no. Watch the movie."

Y/n kicked the blonde's legs again, and picked up her blanket, plodding over to Kirishima.

"What the fuck are you doing? Sit back there, now."

"No. I think I'm gonna sit here, with my boyfriend."

"No, you're sitting there, and he's sitting there. Just because you're dating, you can't fuck in the entire house's bathroom, then come downstairs and cuddle."

"We didn't fuck in the bathroom, asshat. And we can cuddle, just because we're dating."

"I heard you two in there! You weren't quiet at all! And I know what cuddling leads to, so you'd better not go at it again to tonight."

"Fuck you, Katsuki."

"Fuck you, Y/n."

Kirishima listened to the siblings bicker, and bit his lip, wondering if he should contribute.

"...never had a girlfriend, so how would you kn-"

"Y/n, I think we should just go upstairs. You guys shouldn't be fighting. Especially if it's because of me. It wouldn't be very manly of me to let this continue."

"Okay, Eji. Come on."

Y/n held her hand out to Kirishima, leading him to the stairs.

"Hey! We're not done here, you bitch! And you are not sleeping in the same room!"

"Yes we are, Katsuki. Good night."

She dragged him to her bedroom, collapsing on the bed. He laughed and joined her, coiling an arm around her smaller frame.

"You're so cute. I wish Bakugo wasn't so against our relationship."

He sighed, kissing her cheek chastely. She giggled, scrunched up her nose, then sighed too.

"Yeah, but I like you, so I don't care what he thinks."

"You know, Mina told me if we both liked each other, it didn't matter what Bakugo thought. I guess she was right."

"Yep."

She flicked his ear and he flinched, then laughed with her.

"We should probably sleep now, we're going back tomorrow."

"I love you, Eji."

"I love you too. Now, roll over - I wanna hold you."

She did as told, rolling into her side and letting him pull her into his chest. His arm stayed firmly around her waist and his chin rested on her shoulder.

Their peaceful breathing and close proximity calmed both of them, and the drifted into sleep.
