Steve is more or less an ideal service top. He absolutely has a mind of his own and will use it in bed; he's capable of true dominance and just as capable of submission if he's approached right. But this softer, more nebulous kind of power exchange suits his physical strength while covering for any lack of experience (which is not a problem for foreplay or giving head, but might show up when they get into the bed for real).

Once he gets to work with his mouth, his hands follow suit, one stroking between Tony's thighs, the other sliding up under his shirt. And if he's good at what he does, the sheer enthusiasm he shows for it only makes it better. He looks up from time to time to watch his face, but mostly he's focused on action, eyes shut and making quiet, ragged groans like he's getting just as much out of this as Tony is.

He is. Tony isn't the only one that benefits from shutting his brain down, and since there are no substances that work for Steve, he has to find activities to compensate. This is a good one, and he's been overwhelmed for days. The process of quieting himself down mentally, emotionally, is starting to click.

Which is why, when Tony whimpers his signal to stop, he's slow to respond until hands press against his hair. Why he makes a pained little sound of loss as he draws back, and why he looks utterly confused by the question he's asked for a full three seconds before standing and scooping Tony up again, bridal-style, without asking permission.

This way, he can at least see and get to where he's going. It's not until he's set the other man on the bed that his verbal centers kick back in, and what he wants to say is 'do they keep condoms in the nightstands here or just Gideon Bibles?' but only the central concern of that question emerges from his mouth: "Condom? Lube?"

His voice sounds a little raw, too.
