Not Exactly What I Wanted (слэш)

Tony has always been happy to piss off Alphas who try to control him - especially Howard Stark. Unfortunately he managed to push his father just a little too far... and the man arranged to have him auctioned off to the highest bidder. Now he's married to a guy he hardly knows, one that is too damn patient and too damn nice. There's no way that isn't an act, and Tony is resolved to be a little shit until he finds out the limits of his husband's fake personality.
Though he's been back from the war for a while, Bucky has been left scarred by the experience. The most prominent one is the personality that came into being because of Hydra's torture and brainwashing attempts when he was captured. They were rescued before they became the Winter Soldier, but Winter is still very much sharing space in his head. Winter has never responded to anyone positively... until they met Tony at an auction Bucky had been dragged to by a former commanding officer. They are both captivated by the Omega and buy him despite their better judgement.
