More is what Bruce wants, and more is what he gets. Tony's good at reading that part. He pushes him back against the wall with his body, hip to hip, so he can get a little dirty grind in there and coax another groan out of the man. It's good, the way he responds. Natural. And far less awkward than he tries to make it be.

Once Tony gets under that line of defense, he knows it's definitely a force neither of them can stop. And he's not even going to try.

He lets Bruce guide him, tilting his head so he can suck a red flush on the side of his neck. It's a mark that he knows will stick, and he's proud of that. It's a sign of how far they've come. He slides a knee between Bruce's legs, gently rocking up against him so that he can fit their bodies just right. No surprises, of course. But if Bruce asks for it, Tony will give him all he's got.
