but you’re forgetting the blatant gross over-the-top flirting
we all know bucky’s a flirtatious guy, always had a date on saturday night back in the 40s and all, but so is sam! he fearlessly chatted up captain america and the black widow both in the span of about five minutes like the freakin hero that he is (you go sam, live the dream~)
and bucky’s no exception; bucky’s the overtly flirtatious type, so once he winks at sam over a cup of coffee, gaze lingering just a bit too long, it’s on.
they spend a week making eyes at each other; bucky brings coffee to the va during sam’s break, sam gets him flowers, honest to god a bouquet of flowers, and the whole thing is punctuated by sexually charged banter and ridiculous pick up lines.
and then bucky knocks on sam’s door, a little too late for it to be polite, and when sam opens the door it’s to a bucky that looks nervous. he’s fidgeting, shifting his weight from foot to foot, metal fingers whirring.
and without preamble he looks at sam and says, “so, this flirting thing, it’s fun, but do you -” he trails off, gesturing vaguely, dropping his gaze. and there’s something so raw and fragile about it.
"may i?" sam asks, and bucky nods, still not meeting his eyes, so sam steps into bucky’s personal space and tips his chin up and kisses him, very gently, on the mouth.
“does that answer your question?” he asks, stepping back just a bit.
“yeah, i think it does,” says bucky.
