"Well, I was thinking," Shinsou said as he pressed Kaminari back into the bed, his lips against his neck, "that'd I'd like to start by returning the favour."

Kaminari shivered. Start with that? His swallow was audible. "And then?"

"And then," Shinsou kissed his way up his neck to his jaw, "I could," Kaminari's toes were literally curling in anticipation, "Maybe use my fingers."

Whoa. Yeah okay, that sounded really good right about now. He'd only messed around like that a few times but he really wanted to know what it was like to have Shinsou do it.

Hearing Shinsou talk like that was turning his bones to liquid. "To do what exactly?"

Shinsou pulled away enough to look down at him with a heated half smile. He knew Kaminari liked his voice so it made sense he would like this too. "I'd use my fingers, kitten, inside of you." He whispered much quieter, "To give you a taste of how it might feel when I, how did you put it, screw your brains out?"

Kaminari was pretty sure that undignified noise just came from him.

Shinsou sat back on his knees over Kaminari's lap and he could feel the affect he was having on him. He dragged his finger along the blond's lips and Kaminari wordlessly opened so Shinsou could slip his fingertip into his mouth.

"I'd love to see your face as you come while I'm fingering you." Shinsou watched as Kaminari's pupils dilated as he spoke, lips wrapped around his finger and a flush creeping down his chest.

He dragged his finger back out and ran it over his bottom lip as he asked quietly, "How does that sound?"

"Yeah. Yes." He had to clear his throat to speak properly. "Let's do that."

Shinsou tried not to laugh at his eagerness because he felt that same sense of urgency. "Should we get started then, gorgeous?"

Kaminari nodded frantically and Shinsou couldn't stop his laugh that time.

He gripped the blond's hips and pulled him a little further down the bed so he was laying back properly and ran his hands up under his shirt. He bunched the fabric over his chest so he could kiss his way down his body.

Kaminari could feel the hot trail of Shinsou's lips on his heated skin and he made a trail of goosebumps pop up as he moved on.

Shinsou got to the top of his pants and reached for the waistband. He curled his fingers around it and paused, lips hovering over flushed skin.

The sight of Shinsou looking up at him, eyes half hidden beneath his lashes, from between his legs shorted out his brain. He only managed a nod and Shinsou slid his pants down his thighs.

"W-wait," Kaminari whimpered and Shinsou sat back immediately.

"Condom," Kaminari reassured.

Shinsou nodded and got up to make sure the door was locked. When he turned back, was greeted with Kaminari's ass covered by only his tight black boxers while he flipped onto his stomach to rummage in his bedside drawer.

Kaminari must have heard his sharp intake of breath because the blond giggled before wiggling his hips.

"God, your ass, Denks," Shinsou breathed, reaching out to give it a firm squeeze. Kaminari covered his moan by rolling back over and passed him a condom and a small bottle of lube.

He moved Kaminari's hips to the edge of the bed, letting his legs drape over the side, and dropped to his knees on the floor. Kaminari's big bed really did come in handy for some things.

Shinsou mouthed at the hard line of Kaminari's erection which was clearly visible beneath the thin fabric of his underwear and his hips bucked up off the bed. Shinsou gripped his hips to keep him in place and did it again.

Kaminari groaned at the teasing contact and flopped his arm over his eyes, knowing that if he watched, it was sure to be over all too quickly.

Shinsou slowly tugged Kaminari's underwear down and his erection sprang free. He wrapped his hand around him and started to slowly stroke, finding that slow, torturous rhythm that worked last time.

Kaminari blindly found the condom on the bed with his other hand and passed it to his boyfriend. "Here, better sheath the lightning rod."

He felt Shinsou's huffed laugh against his thigh. "Dick jokes are not appropriate when I'm on my knees for you."

Yeah, god he really was on his knees for him. Shinsou had slung his legs over his shoulders as he knelt on the floor between his thighs. Kaminari couldn't think about that too much because this would definitely be over too quickly if he did.

Kaminari's whine caught in his throat when Shinsou took his hand away and reached for the condom. It was quickly rolled on before Shinsou pinned his hips to the bed with one hand on his stomach and he felt the wet heat of his mouth envelope him soon after.

His mouth was warm and tight and wet and the noise Kaminari made was pathetic. He really hoped Iida wasn't in his dorm next door but the thought turned back to static when Shinsou hummed and dragged his lips back up.

Kaminari concentrated on trying to be quiet while Shinsou took him apart with his mouth. He only realised he'd sunk his teeth deep into his lip to keep quiet when there was a sting of pain.

He could already feel the telltale signs of his oncoming orgasm so he let go of his lip to warn, "Cl-close, Tosh."

Shinsou pulled off him so he could push his knees back into his chest. He pressed kisses into the soft skin of his thighs as he opened the lube and coated his fingers with what was probably too much.

He looked back up at his boyfriend laying spread out for him and he groaned at the image he made. He wished he could see his face but he knew how intense this probably was so he wouldn't make him look at him. Next time though he wanted to see his face as he pushed into him.

He placed the tip of his finger at Kaminari's hole and traced little circles, just enough to let him get used to the sensation and he felt him start to relax.

He let the tip of his finger sink into him on the next circle before pulling back out and was rewarded with a very pretty sound so he did it again.

He slowly worked his finger inside, feeling his tight heat clench around him. "You're doing so good for me, kitten."

He couldn't tell if Kaminari's whimper was from the praise or the way he pulled his finger back out and pushed in again. He took his dick back into his mouth and swirled his tongue back around him.

Kaminari finally let his arm drop from his eyes and Shinsou met his gaze. The golden, blown out look was too much and Shinsou shoved his hand into his pants to fist his own pulsing shaft.

Kaminari's pulse was pounding so hard in his ears it was all he could hear and when Shinsou added a second finger his legs started to tremble against his chest.

Shinsou's fingers pressed against something inside him and it made pleasure shoot through his veins. "Holy shit, more of that."

He rest a tentative hand in Shinsou's hair as his other hand fisted his own shirt. Shit, he hadn't even taken it off. His back bowed off the bed a little and it made his hips grind down onto Shinsou's fingers. He gasped and held the breath in. It only took a couple more bobs of Shinsou's head before Kaminari needed to shove his knuckles against his mouth because he was coming harder than he ever had before.

By the time Kaminari opened his eyes again, Shinsou had climbed onto the bed next to him. He was looking far too put together for how hard Kaminari's heart was still pounding.

"You good?" Shinsou asked.

"Fuck, Tosh. I think you killed me."

Shinsou chuckled softly and wound his arm around him to pull him to his chest. "I'll head out soon so you can have a shower. You might want to avoid your class rep though, even with something in your mouth, you're still loud."

Kaminari groaned in embarrassment. "Can't I just like, never leave this room again?"

Shinsou snorted in response and pulled him tighter against his chest.

"Maybe next time you should use your quirk on me," Kaminari teased.

Shinsou grinned and it was all dark angles and teasing lines. "Or I could gag you instead."

Kaminari spluttered and hid his face in his shoulder. "Remember when you got flustered easily? Where'd that guy go?"

Shinsou kissed his temple. "Payback, kitten. For all the times you made me so damn flustered."

Kaminari huffed a laugh through his nose. "I love you."

Shinsou kissed his temple again and spoke the words against his skin. He'd never get used to hearing that.
