Pretty Peaches 2 (1987)

Peaches is almost 20 but her divorced mother forces Peaches’ boyfriend Bobby to leave when she hears them having sex. Suffering a cramp from the sudden stop, Bobby accidentally tries leaving through the mother’s bedroom and hides behind a curtain when she gets back. She then catches him peeping on her and – under kitchen knife point – forces him to strip to see what it feels like to be peeped upon. Once he’s nude like her, Bobby’s cramp worsens. The mother decides to take advantage and fix it for him. Peaches, who thinks her mother is prude, looks for sexual advise from her stepfather who tells her to just ask around and to never be a tease. His scantily clad secretary overhears this and seduces him as soon as Peaches leaves despite his threat of sexual harassment charge. Peaches then hitchhikes with a trucker to her step uncle. While peaches is in the bathroom of their shared motel room, the motel’s prostitute offers her services to the trucker. Peaches joins to watch and learn. .
