Prompt: Steve/Bucky, Bucky sold his soul (maybe)
Bucky, in a fit of youthful stupidity, sells his soul to what he believes was the devil (this being Bucky, it was probably to save Steve's life). He knows he's living on borrowed time, and he's got no intention of letting Steve know.
Steve eventually finds out when the not!devil comes collecting (post CAWS, perhaps?).
Before he goes to Europe, Bucky summons a demon in order to make sure Steve will stay safe. There is no way, of course, for this to go badly.
