Cambalacho Sexual (1986)

The blonde has curly hair, slim build, and wears large hoop earrings plus a necklace that rests between her tits. She’s on the bed early, posing with one hand behind her head, showing off her pierced neck. The scene shifts to three people on rumpled sheets — blonde, another woman with short hair, and a guy. They’re tangled up under low light, girl-on-girl grinding while he jerks off, then moves into doggy behind the blonde. She takes it deep, arching her back, and later rides him face-to-face while the other woman leans in to kiss her. Camera stays mostly wide or medium, no shaky close-ups, so you see full bodies during position switches. Action feels unscripted — they switch partners twice, one girl switches from sucking dick to sitting on his face while he eats her out. Lighting stays dim throughout, just enough to catch the bracelets on her wrist and the restraints tied to the bed frame.
