The Dirty Dolls (1973)

Starts with six girls in a living room—blonde with inked arms, a redhead MILF with freckles, a couple of skinny brunettes, and a black-haired chick—all drinking and laughing in their underwear. The redhead MILF gives this look like she’s about to wreck someone, then the camera cuts to a guy on the phone grinning like he’s setting up the next round. First real action is him face-deep between the legs of a brunette with long straight hair, her legs shaking while she grips the sheets. Later the blonde and another brunette get into it on the kitchen counter, kissing and fingering each other while the guy watches and jerks off. Doggy style with the tattooed blonde is the money shot—she takes it deep, moaning loud, and you can see every thrust in close-up. Lighting is dim but clear, so you don’t miss any detail.
