Movies like Private Pleasures (1985)

Teri and Caerage are a classic butch/femme seduction scene. In a ritzy penthouse apartment they dress up for each other's pleasure, then pop the champagne, lick off the whipped cream, and end up on the floor in a fucking scene that will astonish you. And someone is watching them! Voyuering Mariko sees it all and then takes her pleasure too.
