What it says on the tin: in the backalleys of Brooklyn, Bucky catches wind of a plan by one of the gangs to get a hold of Steve and subject him to a brutal gangbang (maybe with the intention of coercing him into being their own pet prostitute afterwards). Instead, Bucky offers himself up instead - really piling on that charm and swagger - and doing what he has to do to 'convince' them that he's a better choice and has a lot to offer. Cue Bucky mouthing off while they all take turns with him, and limping home with a dozen guys' come dripping out of him and a pocket heavy with a fistful of come-stained money. Maybe it happens again.

Whether and how Steve finds out is up to you.
