Shades of Ecstasy (1983)

One of the girls has long dark hair and a lean, tight body — she’s bent over a mattress early, getting pounded from behind while another girl watches. The second brunette is shorter, with curly hair and a thicker ass, sitting on the guy’s face after he finishes cumming in the first girl. The third girl is blonde, petite, and starts off making the bed like some weird fetish setup before stripping down and sucking the guy off while he jerks himself. The whole thing’s shot in dim light with wide angles that show the dirty industrial space — exposed pipes, concrete floors, the kind of place you’d film a post-apocalyptic sex scene. They switch up positions constantly — doggy, missionary with legs pulled wide, reverse cowgirl riding backward — and the guy cums on the brunette’s back after creampie sex. Camera stays steady, no fake moaning or weird filters, just raw-looking sex with natural movements and real-looking bodies.
