Bucky kissed a trail from Billy's lips down his neck, making soft little sounds of encouragement. He knew by now the general shape of Billy's magic, how careless words could come with unintended consequences. Bucky recognized the effort it took, especially combined with the topic of the request. He gave a final nuzzle and a little nip to the join between neck and shoulder before pulling back a little bit to speak.

"You want me to take you apart," he summarized. "You know how focused I can be and you want all that attention not on a mission, but on you and only you." His hand dropped to Billy's hip and his leg pressed closer, guiding the motion of Billy's rutting. He shifted close enough to kiss, speaking right against Billy's lips. "Piece by piece, you want me to pull you out of your mind until all that's left is your body, endlessly strung out on orgasm after orgasm, all night long."

Something Bucky could give, and safely so. And something Bucky wanted, that feral part of him that needed to possess. But he could also tease, and tease he did by pulling back and shrugging — though his grip on Billy's hip encouraged him to keep riding Bucky's thigh. "Or I can just fuck your face. Your choice."
