Bucky & Jack
While a very small part of Jack's mind associated metal limbs with Cybermen (that was a story that was definitely staying under wraps here), his body remembered enough men who had come home with wood or aluminum in place of flesh that his soft sigh came easily at the touch. It wasn't hard to tell that Bucky was a bit out of practice, but that was all right.
He drew back slowly and reluctantly as his body reminded him he actually did still need oxygen, letting his tongue and lips linger slightly as he did. He didn't quite trust himself not to push a bit further by instinct, remembering what he would have done with The Captain right on the dancefloor if he'd stayed. Still, he was smirking as he drew away, and he kept his head bowed close. He could've said something about living up to his self-proclaimed reputation, but he'd stung a few lovers in the past with those remarks and he really didn't want to do that here.
