The more Bruce gets into it, the more Tony is fighting the urge to break his one restriction. It's hard not to want to push Bruce back and pin him down. To just kiss him and caress him until he's writhing helplessly in the heat of lust. Patience is not Tony's strong point.

But he holds back. Instead, he cups his hand over Bruce's cock and smirks, giving him a look of absolute mischief.

"Anything? That's a dangerous word, Banner. You sure you want to trust me that much?" He's joking of course. Tony leans in, nipping the edge of Bruce's jaw before he whispers huskily against his ear. "I want to see you when you come apart."

It's a little more than daring, considering he knows how Bruce tends to tense up at any suggestion of conflict, but he hopes that Bruce trusts him enough to allow this. A little dirty talk never hurt anyone. And he wants to hear it. Tony can't pass that chance up.

"I want you to strip down for me so I can see you naked, and then I'm gonna get my mouth over every bit of you."
