Bilitis (1977)

One of the blondes is wearing a tight white top that gets lifted during the bedroom scene — you see her bare tits as she rides the guy on the bed. They’re all in their early 20s, slim, and dressed casual like they just hung out at home. The vibe starts off relaxed — they’re sitting on the couch, talking, chess game half-finished on the table. Then later you see the same couple in bed, dim light, her straddling him facing forward, moving slow. There’s also a scene in the kitchen where the two women sit across from each other, one tucking her hair behind her ear while sipping a drink. The outdoor shot shows them loading a car with suitcases like they’re coming back from a trip, but no context links it to the sex scene. Camera stays wide for the group shots, close in during the intimate moments. The sex is quiet, not rushed, with natural movement — you can hear the bed creak slightly. The second blonde appears only in non-sex scenes, so she’s just part of the setup.
