The remark actually caught Jack off guard. He wasn't exactly used to the Doctor flirting back with him. Still, he wouldn't be Jack Harkness if he didn't meet it with his signature charm. He closed the distance between himself and the Doctor, taking one hand and wrapping it around him to pull him against Jack's half-naked body.

"Don't tempt me. Don't think I haven't had that very same train of thought at least once." With a grin, he leaned close to his ear to whisper, "To have you bent over that console, screaming my name while I took you into ecstasy? Yeah, the thought occurred to me once or twice."
