Bucky doesn't move, doesn't try to pull away when Steve grabs for him. He simply crouches there, watching Steve's face, and lets Steve do what he wants - including lean in to kiss him.

His lips curve up into a fond smile as Steve pulls back, and he shakes his head a little. "I'm not offering it just 'cause you did. I mean, fair's fair, sure - but I want to." He kind of really, really does - he wants his mouth all over Steve, every inch - and that means every inch. "I wanna find out what you like. And I wanna see if I can't find things you didn't know you liked."

Like, you know, going slow. He's grinning full tilt by the time Steve tells him to cut out the teasing, to which Bucky just laughs softly, and pushes at Steve's shoulders again, shuffling forward to position himself between Steve's legs, hooking his fingers into his underwear and pulling it down enough to free Steve's cock from its confines. "A whole three, huh?" he teases, before he starts working Steve's jeans and underwear down his thighs, seeing if Steve will let him pull them off.
