"Your hands, though," he croaks helplessly. Presumably it's meant as a compliment, given his earlier confession about some of the things he likes about Stark. Steve's own hands move up Tony's back to brace under his shoulderblades, clinging with impressive strength, and his pelvis moves, pushing up into Tony's grasp. Thrusting.

"F-for you, huh?" He adds, gaze flicking back to the other man's face, locking his eyes on Tony's face. "Yeah--yes. God, yes..."

That's when he runs out of words, dissolving into sharp gasps and whimpers, back arching enough to lift his hips off the cushion and bounce Tony in his lap. He can't keep his eyes open under the final onslaught of pleasure, squeezing them shut and gritting his teeth against the cries that want to break free from his throat.

The orgasm is intense, and it's messy, leaving his chest and belly slick and shiny with release. As the spasm fade away, he gulps air again and stills, blinking rapidly because tears have sprung to the corners of his eyes.

"Uffhh..." he says softly after a moment. It might be a while before he can give any kind of intelligent feedback, but his lips curve into a giddy little smile.
