The silence stretches a little, to the point that he almost thinks it won't break. Tony does break it though with quiet words that wash over his skin, words heavy for all that they're carried on a puff of breath. Bucky noses a little further into his hair, leaving a heavy sigh there before turning his face to rest his cheek against the top of Tony's head.

"You've read my words too." He knows that Tony's read the book, or at least read a translation of it, if not the original Russian. He never did ask how the other man had gotten his hands on it after Siberia, and he doesn't truly want to know. "You know you could control me."

Not that they've ever tried it. They've never even really talked about it, but they've talked in enough adjacent directions for them both to put it together. Still it's not quite what Tony's saying and Bucky knows it. Tony had seen his cryo tube, his chair; more than just reading the book, he'd seen those pieces of Bucky's life bared to him. It's a hell of a lot different seeing the evidence than just reading about it.

"Do you want me to try to stay more?" He doesn't know if he can, that's why he won't make it a promise, but he thinks he could try to figure out how to give Tony more of his time, to spend more of it here. It will mean balancing things elsewhere and he knows that will be a mess, but for Tony he'd try to figure it out.
