Bucky & Jack
Bucky was self conscious about his arm, the heavy scarring around it where it met his shoulder. So far, the only people who'd seen it were Steve and Finnick. He'd kept a shirt on at all other times around camp when a lot of other people walked around shirtless. He was relieved that Jack was treating it as nothing to be concerned about. That was helpful to him.
Leaning in, Bucky kissed Jack again, a bit more aggressive about it than his utter tentativeness of before. It was easier this second time to let his lips part and actually deepen the kiss, to not worry about it when he touched Jack's face again with his metal hand. He was more than willing to drag this out a bit, savor it. Kissing was nice, and he didn't have to worry about being very vulnerable while doing it.
