Noite dos Bacanais (1981)

Dark-haired woman with thick curls and a slim build starts off lying on the bed, wearing little, skin glistening under low light. Another woman joins her, both white, early 20s, moving slow at first — lots of close contact, hugging, kissing deeply before sliding into grinding. They shift to missionary, one on top, rocking hips in a lazy rhythm, camera fixed just above the bed for full-body view. One of the guys — dark-haired, average build — shows up later, but the real focus is on the women. The oral work is detailed, heads bobbing low, tongues visible in close-ups. Scene switches briefly to two Black guys in their 20s going at it on the same bed, muscular, sweaty, full-on anal with deep thrusts. Lighting stays dim throughout, gives it a private, voyeuristic feel.
