Bruce tries to hold on, but Tony's giving him exactly what he needs -- well, it's more what he doesn't need, since the invitation to let go is only fraying his control even more -- but he definitely never lets himself be this free, never lets himself have so much. Really, he doesn't have much hope in being able to keep up that domineering control; he's known that he idolizes Tony in a way, as much as you can idolize someone with their faults included, but Tony is so big, and free, and eager to give, and he sweeps Bruce up in it without really giving him time to catch his breath. It's amazing, and frightening, and he wouldn't want it any other way.

He chokes off a groan, and tugs Tony in for a fierce kiss; it feels safer to communicate what he wants and how much he wants like that, because he's afraid to say it in words, almost like he's not allowed to say it in words. He barely allows himself to want anything, and if he really lets what they're doing sink in, he's afraid he might freak out and leave. He doesn't want to do that; he doesn't want to say no to Tony here, now.

His hand slips free from his pants to instead curl in shirt, pushing it up his chest.

"Off." There's no question that it's an order; there's something primal coming out in him, and he isn't sure if he should hold it back or not, so used to not trusting his instincts.
