Bruce does see the expression on Tony's face, but he isn't that all willing to comment on it right now. No, he'll... think about that later. He just wants to live in the now because the now is good and fantastic and thinking too much won't help him in this situation.

He allows Tony to lead him to the bed, settling down and scooting to a good position so that Tony can come to bed with him as well. Another brief smile crosses his face before it falters to a low hiss of pleasure as Tony teases him with his fingers between his legs.

"Anything," he replies, opening his eyes again. "Anything you want. Just--" Bruce pauses for a moment, hesitating, but decides to hell with it and says it out; its not like Tony wouldn't figure it out anyway. "Just tell me. I want to hear you talk."
