Bucky / Clint
Whatever they were doing was amazing, the best, and Bucky wanted more of it. He felt like he was gaining more and more of his own humanity back whenever he and Clint were together. Laughter was so much easier, it came so naturally. He felt like himself, like who he'd been before HYDRA and everything else and that was a feeling Bucky never thought he'd have ever again. But it wasn't just that; it wasn't because Clint was doing those things for him that Bucky cared for him. It was just because he was Clint, and Clint was wonderful.
When he turned and the two kissed, Bucky slid his human hand up to cup the side of Clint's face. He held it there, and in turn held onto the kiss for a little while longer than what was probably deemed appropriate for a public setting. He didn't care. It was Clint's birthday and he wanted him to feel as special as Bucky knew he was. "Yeah," he whispered against his lips, before he stole another one of those delicious kisses.
