Knocking Optional
Ever since Peter moved in to stark towers, Tony had leared the very hard lesson that teenagers needed privacy.
On some level, Tony knew that it was true. He had been a teenage boy once too, and he had one or two horrifying memories of his parents walking in an him while he's got his hand wrapped tight around his cock, but he never thought about that with Peter.
It happened once, Peter had come home from school and immediately retreated to his bedroom. Foolishly, Tony had assumed that Peter was just working on his homework and walked right in without knocking.
There was Peter, splayed out on his bed, flushed all the way down to his chest, thrusting his hips up into his tight fist. Tony felt his mouth go dry. He watched, frozen, as Peter's mouth drops open and he lets out a choked off moan, clearly trying to be quiet, just before thick white cum spurts from his cock and lands on his stomach, a few drops rolling down his shaft which he seems to use as lube, his hand twisting along his cock as he spreads it around.
Tony couldn't help but be a little stunned at the way Peter doesn't even slow down despite having just cum. He watches the way that Peter's slim hips flex up and then down, back arching and toes curling. He shouldn't be here, shouldn't be watching this and yet...
Instead of turning around to leave like he should, Tony slips his hand into his pocket to squeeze his rapidly hardening cock. Before he can stop himself, a small whine leaves his lips.
Peter freezes, his eyes flying open and his head turning to the side, looking wide eyed at his mentor. "M-Mister Stark, I didn't know you were there, I just, I was just..."
"I know what you are doing," Tony cuts him off, suddenly feeling emboldened and Peter's stuttering. "I was just wondering what those spider powers mean for your stamina and refractory period." He smirks.
Peter sits up a little, shocked, before his eyes darken with arousal. "Why don't you come over here and find out for yourself?"
Maybe privacy didn't matter to Peter as much as everyone had thought.
