9 1/2 Weeks(1986)
In this legendary erotic drama, an art gallery employee played by Kim Bassinger finds herself seduced by a man she barely knows, played by Mickey Rourke. Soon she is dragged into a wild world of erotica, one sexy game at a time. This is a film that helped many an 80's teen boy during his transition into puberty.
This is the theatrical trailer for the movie.
