Bucky leaned back just a little bit. "James is sterile. And he's not sure when it happened, he just knows..." He hadn't told Steve that part. He brought his hands up to capture her face, his thumbs lightly caressing over her cheeks. "I'm not trying to push you away. I'm saying that I don't mind them all being his." He spoke around the lump in his throat. He wasn't sure why he wanted something that was only his, when he adored Steve's kids like they were of him too.
He was leaving himself out raw again. Was she going to stab at the rawness again? Or was she going to get what he was telling her. He wasn't sure how much he could take her jabbing at things that hurt.
