Breath shuddering, Billy honestly wasn't so sure he could wait in that moment, despite how tired he was. Feeling Bucky's possessive touch, that hardness rutting against him...hearing those delicious words.

"Jesus-" he managed shakily before his mouth was claimed, stealing his breath away and leaving him panting by the time Bucky was through with him. He wet his lips, hips grinding subtly without really thinking as he tried to catch his body up with his mind, nodding wordlessly in agreement even as he moved to chase down another kiss. He wanted both simultaneously, waring internally between pleasure now or the reward for restraint. His fingers ghosted down Bucky's chest and over his hip, but he made himself stop shy of taking him in hand. He nodded again, trying to hold onto that resolve. "You're going to get me off again all ready if you keep talking like that."
