The Body Beautiful (1997)

Camera starts on a muscular guy in a dark gym, but he vanishes after the first shot — turns out this isn’t about him. A slim young brunette with long brown hair is seen alone, wiping shelves in a bright storage closet full of cleaning supplies. Later she’s on the floor near gym equipment in dim light, face close to another girl, both grinding hard against each other. The older one — early 30s, short dark hair, wearing a fur coat — shows up in a wide outdoor shot with the girl and a slim guy, but he disappears too. All the action centers on the two women: their mouths locked, bodies pressed, one hand sliding under clothes during close-ups near a wooden beam. Lighting stays low in the interior shots, giving a raw, unfiltered look to the grinding and kissing — not full sex, but definitely intense making out with visible movement and touching.
