La peccatrice (1982)

A muscular black guy rides a slender blonde from behind in doggy style, deep thrusts, face in the pillow. Another black guy stands over her, jerking off, waiting his turn. They switch fast — now she’s on her back, one guy in her mouth, the other lining up for missionary. Camera stays wide in most shots but cuts to a tight close-up of a pale, toned ass in the middle of it. The lighting is low, warm, looks like late night in a messy bedroom. One guy leans in from the side, grinding into her while the other fucks her hard — she’s moaning, eyes shut, nails in the sheets. No talking, just heavy breathing and skin slapping.
