Self control. That term is the bane of Tony's existence right now. All he wants to do is touch Bruce. To strip him down and kiss every part of him until he's bucking up into him without any worry or reason left. But of course Bruce would bring it back to sense. He's much more responsible and mature than Tony, and that part of him is something that Tony respects. He admires the mind that can so perfectly control his body.

He slows down enough to grudgingly give Bruce the space he's pushing for. The exposed throat is ridiculously tempting, but he likes Bruce. He does. So he holds himself back, groaning softly in protest and letting the pad of his thumb swipe over the tip of Bruce's cock. Now that he's gotten a taste of what the man is like when he's into the moment, he's not about to let him go that easily.

"Right. Self control, self control... You know, part of the fun is not stressing out over these things, Banner." Tony's teasing, though. He knows that Bruce needs that control, and he makes sure to be gentle, easing off of the contact while his friend regains composure. It doesn't stop him from teasing, though. Feathery light touches over his hips and up his navel, Tony lets his fingers explore the warm body beneath him with near reverence. Because he can, and he does want Bruce to feel special. He is special.
