The Booty and the Mechanic (слэш)

Tony Stark was in his garage.
Tony fucking Stark, the High School’s Physics Teacher, was in his garage. At goddamn six fucking thirty a.m, half an hour before opening, because the man had been banging at his door as if there was a matter of life and death.
Or,
Having Tony Stark march into his garage as if he owns the place puts Bucky on edge with rage and annoyance. Though it would be easier to stay pissed if the man stopped wiggling his butt practically into Bucky’s face. Because damn, that sure is a nice butt, huh?
