"You like that I can get you off just by talking to you," Bucky pointed out. "You're already thinking about times when we're separated and all you have is my voice. In fact—" he slid his hand down Billy's thigh, tugged that leg up over his hip. It brought them close enough to really move together, rutting against each other with increasing urgency. "—in fact, you're already thinking about our next mission together, just you and me, and how I could start saying dirty things to you at any time. You want that too, don't you? You want to have to keep yourself quiet and hidden while I'm taking you apart."

An attractive image for sure, not that either of them would ever truly jeopardize a mission to that extent. Still, it was fun to tease, especially the more they moved against each other. Even tired Billy knew exactly how to touch Bucky to drive him wild.

"I promised I'd take you until you couldn't physically go anymore," he murmured. "And you keep offering yourself to me, tired or not. Say it one more time and I won't stop, won't let you rest until you've come at least twice more. Can you handle me, if I let go of my restraint?"
