Mina smiled at Kirishima and Bakugou's quick retreat and wondered if there would be a new couple in the squad now. Finally!

She finished her own glass of water and turned to the others, giggling, "Anyone wanna swap rooms? I'm pretty sure there's gonna be a whole lot of noise coming from their rooms from now on."

Kaminari grinned at her, "You know you're always welcome upstairs. They're probably gonna get real freaky."

Sero snorted and pushed at his shoulder.

Kaminari laughed, "What!? You know I'm right!"

They fell into comfortable silence for a while before Sero stood and reached a hand down to Mina, "Do you want to sleep in my room tonight?"

Mina beamed at the offer and grasped his hand, letting herself be pulled up. They made their way on tired legs up the stairs and collapsed onto his bed.

"Who would have thought a rainy day would turn out like that!?" Mina chuckled.

Sero laughed in return, "Not me, that's for sure." He smiled to himself as he looked up at the roof, "I don't think I'll ever do anything that wild ever again."

Mina twisted onto her stomach and faced him, grinning mischievously, "Who really says we can't though?"

Sero slowly turned over so he was facing her, "What are you saying?"

Mina shrugged, "Maybe the others enjoyed it too and it could be, well, not like a regular thing but not just a once off."

Sero snorted, "I can't imagine Bakugou and Kirishima agreeing to that."

Mina laughed, "Not them, silly, but Kami and Jiro might."

Jiro looked shyly at Kaminari from under her bangs in the now empty lounge, "Hey Kami?" The blonde turned to face her and gave her a tender smile. "I really like you." She said quietly.

Kaminari beamed, "I like you too. I'd really like to take you out on a date."

She gave him a soft smile and nodded, "That'd be nice."

"Wanna stay with me tonight?" He asked softly.

She smiled sweetly back and nodded before making their way to his bedroom.

"I'm pretty sure we both need a shower, can I use yours?" Jiro asked when they were both inside his room.

"Yeah of course." He said but pasted a look of innocence onto his face before continuing, "But it's one of those showers that only works with two people in it."

She stopped in the bathroom doorway, "You're such a dork" she said over her shoulder as she went inside and turned the water on but she couldn't help the little smile the played over her lips at his dumb joke.

She put her hand under the spray to test the temperature but flinched away from the cold water and adjusted the tap again. She tested again, still cold.

She turned to call Kami for help but he was already standing in the doorway, his arms crossed smugly over his chest. "Can I help you?"

"Your shower's cold. I can't get it to work," she huffed.

Kaminari smiled crookedly at her. "Told you it needs two people for it to work."

Jiro rolled her eyes as Kaminari reached in and turned the taps to what looked like very specific spots and the water warmed. He turned to step back out of the shower but Jiro's hand on his arm stopped him.

"You'd better stay, just in case it stops working."

Kaminari chuckled and pulled her to him, "Oh so it's ok for you to make dumb jokes, but not me?"

"I think you're rubbing off on me." She whispered as she ran her hands down his sides. She could feel his cock starting to twitch to life where it was caught between their bodies and she ground herself against it.

He groaned at the pressure and caught her lips with his.

After a heated kiss he pulled away. "If it's alright with you, I'd like to have sex with you in an actual bed." Kaminari said against her ear.

"Fine, just let me wash my hair. I'll be out in a minute."

Kaminari smiled as he dried himself, they were like an old married couple already.

He lay back on the bed and waited for her to finish up. True to her word she didn't take long. Maybe because he passed the time by occupying himself.

Jiro came out of the bathroom to see Kami reclining on the bed lazily stroking his hard cock and smirked at him. "Oh really?"

"Would you like to take over then?" He teased.

Jiro subconsciously licked her lips as she crawled onto the bed. She made her way up his body and his hand fell to his side, "I've got a better idea." She whispered as she straddled his waist.

She ground herself against his shaft, letting him feel her arousal and he moaned at the contact.

She used her hand to position himself at her entrance and started to sink slowly down.

"Wait, wait, condom." Kaminari groaned.

"Don't need one, I'm good if you are."

Kaminari nodded and felt his eyes roll back in his head as she sank down onto him. She rotated her hips when he was finally fully inside her, eliciting a moan from them both.

She pushed her knees into the mattress and started a slow rhythm, lifting up and sinking back down, slowly building up her pace as Kami's hands moved over her body appreciatively.

She angled her hips and let out a long moan, enjoying where he was stroking her inside. His fingers trailed between her legs and brushed over her clit making her arch her back and her breath hitch.

She rode him faster, using his shoulders for support until her rhythm started to falter and he picked up where she left off, thrusting up to meet her, still rubbing her clit.

"Oh fuck Denki, I'm gonna cum already." She managed to gasp out. He watched as her muscles clenched and she tossed her head back, shuddering beneath his hands.

"You're so fucking sexy." The words left his lips without him even knowing as he watched her come apart on top of him, feeling her clench around him and loving every second of it.

He gripped her hips and started pounding up into her as she hunched over him, using his shoulders for support, drawing out her orgasm. Her moans in his ear only spurred him on and he came quickly, his back arching off the bed and his hands holding her lithe body down onto his.

Jiro stayed there for a minute before rolling onto her back, still panting hard and waited until her breathing returned to normal.

"Fuck, that was good." She said breathily and Kami grunted in agreement.

After a minute she turned her head toward him, "Kami, I know you're bi and I've seen how you are with Kiri and Sero, hell even with Mina," she paused for a second, "Now that I think of it, you're a really big flirt." She narrowed her eyes suspiciously at him, "How come you never flirted with me?"

Kaminari scoffed, "If you think I never did then you just weren't paying enough attention to me." He leaned down and kissed the top of her head. "I think you were going somewhere with that before you decided to wound my flirting pride."

She grunted in amusement before continuing, "Well I was just saying how I saw how much you enjoyed being with them so I was wondering if you would want to still do stuff with the others if we became a thing."

He smiled back at her, "Nah, I'd have you."

Kaminari could have sworn a flicker of disappointment crossed her face and his eyebrow ticked up, "Would you?"

She pinched her lips together nervously, "I had a lot of fun today but it's not like I'm interested in any of them any more than in the bedroom. But if you don't want to then I wouldn't."

Kami nearly tripped over himself to stop her words, "No, I mean, yeah we could both still do stuff with the others, if that's what you want, I just didn't think you would."

She shrugged a little at him, "I think it could be fun."

Kaminari shook his head a little, "Who would have thought reserved little Kyouka who nearly died when she saw Mirio's willy would have been the one to ask if we could-"

His words were cut off as she shoved him backwards and pinned him to the bed, they both huffed out a laugh at his words while his arms snaked around her.

"I think we'd better go see the others." Kaminari said, wondering how he'd ever gotten so lucky.

A soft rap at the door had Mina looking up. "Come in." She called which made Sero mutter "Not like it's my room or anything."

Jiro came in wearing her PJs tugging a half dressed Kami behind her.

"Hey guys, what's up?" Mina asked.

"I uh, have a question." Jiro asked, a hint of her earlier nerves showing through.

Mina discreetly shot Sero a look and he returned it with a grin. "Oh yeah? What's that hon?"

"Well I was wondering..." she looked to Kami for help.

Kaminari chuckled, "We wanna know if you're interested in fucking around more often."

"Don't say it like that!" Jiro chided while Mina giggled.

Kaminari looked between Sero and Mina who both wore matching innocent expressions, "You two already talked about it!" he said accusingly.

Mina shrugged and Sero had the decency to blush a little, "Yeah we did." He conceded, "We're up for it if you guys are."

They came up with a few ground rules to avoid any unnecessary jealousy before Mina smiled slyly, "What about the other two?"

"I feel like they'd be a package deal, couldn't have one without the other. Anyone willing to do that?" Sero scoffed.

Mina and Jiro scrunched up their noses but Kaminari shrugged, "I would" but then he laughed, "What are the chances of that happening though?"
