Depraved (1996)

Opella and Dave are engaged to be married, and spice up their sex life by acting out complicated and increasingly kinky sex games and fantasies. When he becomes upset and insists that they are going too far, she storms out of the house. The next morning, he finds a dead body in the Jacuzzi. He calls his brother but all does not go smoothly and the past soon comes back to haunt him.
