Rambone the First Time (1985)

Gloria Leonard runs a pricey house of prostitution, and business is booming. Then her younger sister shows up and announces that she wants to earn her spurs in the world's oldest profession. Gloria is simply thrilled to have her sister training to take over the family business, and she promptly begins her education. She starts with the simple pleasures her business offers its clients — all the traditional forms of sex. Watching Leslie Bovee, who plays the neophyte hooker, performing her lessons is what adult film is all about. Later, she moves on to such lessons as the proper binding and beating techniques for clients who prefer their pleasures with a touch of S&M. A well-done tribute to bought pleasure in all of its forms.
