With each word Billy's breath grew shorter, and his mouth grew drier. There was a trembling undertow to his movements, and he nodded faintly, finger's catching at Bucky as he moved with increasing need. His gaze jumped between his eyes and those lips, ghosting close in want of the kiss he was sure would come when those words ended.

Which let a surprised little broken sound slip past his lips unguarded when Bucky drew back. He flushed belatedly, laughing bashfully, well and truly worked up as he rode that muscular thigh with increasing need. "Ta-take me apart-" he managed, voice catching with how dry it had become. The second option was obviously welcomed of course, if Bucky wanted to use that as a tool to do so.
