Expose Me, Lovely (1976)

The scene opens with a slim blonde in a wavy hairstyle getting held from behind by a lean brown-haired guy on a couch — kind of a soft, intimate moment with his arms wrapped around her tight. Then it shifts to a different couple: a fit brunette with long dark hair riding a light-haired guy on a blue bed, both grinding slow in a dim-lit bedroom. A standout moment is the curvy chick with the big afro — lush thick thighs, full lips — just sitting there in close-up like she owns the room, no clothes, not doing much but still commanding attention. The group scene kicks in with all three performers tangled up on a bed in a living room setup, the brunette taking the guy from behind while the blonde goes down on her. Lighting stays low throughout, giving everything a moody, private feel. The transitions are smooth, no awkward cuts — you see the guy flip the brunette onto her knees, then later pull out for a creampie finish while the afro girl watches and jerks him off.
