Ming dai tao hua / The Seductress (1987)

One of the girls is lying on a bed in just heels and a black bra, getting her shaved pussy eaten while the camera holds a close-up on her moaning face. Another scene cuts to all three standing in a bathroom, fully dressed at first, then two bend over the sink and pull each other’s hair during cunnilingus. They switch fast — one minute they’re fully clothed in what looks like restaurant attire, the next they’re buck-ass naked on sheets, sliding around. A guy shows up later outdoors but doesn’t get involved in any sex, just standing around with a group near cars and a bridge. The indoor stuff is the real focus — natural lighting in the bedroom makes the sweat on their backs visible, and the bathroom mirror shows multiple angles during 69s. Hair-pulling happens a lot, and one girl has noticeably smaller tits but is the most aggressive oral performer.
