It's hard to tell what Tony's expecting. There's a moment where he firmly believes that Steve will let go, that he will need to step back, and the moment will be over. And, really, he would have been okay with that. He would have respected Steve's boundaries, even if right now it probably doesn't seem that way considering his proximity to Steve and the fact that he had his arm around him just moments ago.

But then Steve does something that Tony really isn't expecting, although he has been wanting it. He leans in, Steve's own arms wrapping around him, and Tony's hand moves again so he could move it back to where it was. Maybe it's that warmth that Steve is emitting, maybe it's the feel of his bare skin under his fingertips, maybe it's just how he's kissing him - whatever the reason is, he kisses him back just as hungrily. He pulls Steve closer to him as he does so, his fingers trailing along the muscles of Steve's back as if trying to memorize them. As if trying to stay here forever, as if trying to just enjoy the sensation of it all.

This time, even if there's that annoying little voice in the back of his head, he doesn't pull back. He doesn't wonder if he should stop. He gives in to this overwhelming feeling of needing Steve closer, of not letting him go, and he uses his free hand to settle it against Steve's hip. He can feel the spot where the jumpsuit begins again, and as tempting as it is to push it down a little further, he just moves his fingers so that his hold can be partly on Steve, and partly on the jumpsuit itself.

Before breaking the kiss, Tony catches Steve's bottom lip with his teeth for a brief moment - not enough to hurt, but more as a gentle tease. Even when he stops kissing him, though, it's clear that it's only because he needs to catch his breath and not because he wants to stop.

If anything, since he's still close enough to Steve, he moves in to kiss his collarbone. Before doing so, he asks quietly, his lips almost brushing against his bare skin. "Is this okay?"
