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.

When Peter cums, he clutches onto Tony and the man finds himself cuddling Peter protectively while he cries.

"That was a lot, kid, are you okay?"

"M'good, I just... I just don't want this to end."

Tony swallowed a lump in his throat. "I know, kid. Me neither. But I'll be with you the whole time."

"Thank you, Sir," Peter whispered.

Tony gave a wet laugh. "I think we're way past Sir."

"No we're not," Peter murmured, tucking his face in Tony's neck. "I love you Sir."

Tony hugged him tighter. "I love you too, kid."

"Did I do okay?" Peter asked.

Tony pulled back enough to give Peter an unimpressed look. "Did you do okay? Kid, you did perfect and you know it. I haven't cum that fast since I was your age."

Peter giggled. "Can we do it again?"

"Can we--is this a spider thing?? Going again and again?"

Peter frowned. "Can't everyone?"

"No," Tony laughed. "No, kid. And not an old man like me."

"You're not old."

"I am old enough to be your--"

"Boyfriend."

"Boyfriend," Tony tried the word out. "that's awfully fast, Mr. Parker."

Peter giggled. "We're literally hurtling through interstellar space at a million miles an hour. We're already fast."

"Ugh. You're right. Come here and let me kiss you again. I think I'm getting addicted or something."

Peter pounced on Tony not unlike a spider ambushing a fly, and felt Tony's nice scratchy beard on his face just like he needed.

They did not plan on the weird glowing lady giving them a push towards Earth and all the related consequences.

"I…" Peter paused, then restarted - "I finally know the answer." He said matter of fact. 

Mr. Stark's nostrils flared, and a growl formed deep in his throat. He put his glass down and unbuttoned the top of his shirt, getting more comfortable after a long day. "You've had plenty of time to think on it. Three years is a long time to make a man wait, Peter." 

Peter nodded in agreement. It had been a long time, but the young omega needed it. Needed to be sure, and now he was. "I'm sorry I kept you waiting, alpha. But I know now that I do want it. Want you. Want to be yours."
