The bed dipping was what happened to stir Izuku from slumber, a gently murmured apology coming closer as a body pressed closer to him under his comforter, warm and bringing the familiar smell of his lavender body wash, a cool arm curling around his midsection to pull him even closer as the other snuck underneath his pillow. Izuku hummed a sleepy greeting, feeling the ghost of a kiss flutter against his ear as Tenya did his best to settle against him without jostling him any more than he already had, cool from the shower after tonight’s patrol.
“...Tenya?” He was hushed for his groggy whisper, a thigh bumping softly against his rump. Sleep was calling for him, dragging him slowly back under as he allowed himself to sink back into Tenya’s familiar warmth, cocooned in his embrace. His awareness was slipping, and Izuku closed his eyes again, intent on going back to sleep, before the lightest brush of skin under his night shirt caught his attention.
A heavy breath stuttered against his neck, and fingers curled against his side, skimming against his skin with the lightest of touches. There was a moment, a pause, the hesitation almost palpable to Izuku, and a small smile curled his lips, before he hummed lightly and pressed his leg back against Tenya’s, an acknowledgement and silent permission to continue - if he needed to.
They had talked in passing about it, weeks ago now. Tenya had been nervous, always hesitant about trying something new but eager if they were both consenting and knew their boundaries, what he could and couldn’t do, if Izuku was sure because sleep was important for both of them and interrupting it could have potential problems for their hectic schedules, but Izuku had seen the cautious excitement in his eyes that first time he’d brought it up, cutting across Tenya’s words smoothly with a simple, “I’m sure.” He had been waiting for when Tenya would take the chance to explore the possibility.
Tonight’s patrol must have triggered something, riled him up in a way that others hadn’t before, because although Tenya’s hands were soft against him as they slowly pulled his pants and briefs down, he could feel the hot, heavy breath against his neck coming in quick bursts. Tired as Izuku was, he groaned gently as Tenya palmed his rump, squeezing his cheeks gently and grinding his hips forward where he was already hot and heavy - and, oh, Tenya’s pants weren’t pulled up all the way.
His dick was rubbing between his cheeks, skin catching, dipping into the sensitive curve of thighs, and Izuku felt a shiver go down his spine. It wasn’t anywhere near a smooth glide, and Tenya seemed intent on trying not to jostle him too much, but the tender kisses against the back of his neck made his breath catch and the way Tenya’s hips slowly dragged his hardness against his backside had emotion clogging his throat, warmth blooming in his chest.
Fingers flexed against his cheeks, and loosened in a slow, steady rhythm, and a small spot of wet began to make the movement easier with every gentle thrust. Izuku could feel how tense Tenya’s legs were, straining to keep their gentle pace, and he sneakily tensed his own thighs at a thrust and was rewarded with a sharp nip to his ear, another hushed apology murmured into his hair.
The subtle rocking was almost lulling him back to sleep, but it was getting warmer between them, and Izuku tried not to squirm in Tenya’s embrace as one, two, three more thrusts against his thighs before Tenya pulled away, a hushed groan pressed into the back of his necks as he felt the quick knock of knuckles against his spine before Tenya shivered against him, curling against his body, and, oh, he didn’t want to make a mess of Izuku’s backside, what a gentleman.
Lips pressed featherlight against his cheek, and the mattress dipped again, Tenya retreating from the bed, presumably to wash his hand, and Izuku smiled against his pillow, content to fall asleep in the lingering warmth left behind until he returned.
