"What? I didn't have that much for dinner," Bucky protests, barely able to stop himself from doing that half-inhale and rolling his eyes. But he does try to displace more of his weight onto his legs and stay on his hands and knees, leaning in close to resume their making out activities.

Bucky would point out that it's mostly muscle but he doubts Zemo would stop complaining even with that caveat. He just asks if it's better with a grunt and a nuzzle, without using his words, and goes back to where he left off. Luckily he'd already left a bit of a reddened mark so he knows where to fixate on.
