It'll all be very good. Tony can feel the way Bruce arches under him, responding eagerly to his touch. Oh, it'll be good. When he's like this, it makes it all so much easier to give. He kisses those lips passionately. Something deep and sensual instead of with so much force, and then Tony pulls away. He sits up on his knees on the bed next to Bruce, smirking down at him as he unbuttons his own shirt.

"Pants are looking a little tight," he remarks. He says it casually enough, as if his own erection isn't pressed tightly against his slacks. "I think we'd better do something about that."

There's a pause that is practically tangible, and Tony follows it by wetting his lips.

"Unless you want me to suck you off again. We could leave them on. I bet you look good with your pants at your knees. We should do it again like that."

But later. That will come later, after Bruce is ready and doesn't have to be convinced that every sexual encounter will end in green rage. Right now, Tony is doing his best to blow out his senses (safely, of course) and prove that he can handle more than he thinks he can. It's a gamble, sure, but it's been working so far.
