Sin in the City (1966)

Starts with the girl—slim, curvy, full lips, long black hair—on her knees in a dim living room. She’s sucking one guy’s dick while the other two stand around, tattoos on full display, chatting like it’s just another Tuesday. Camera lingers on her face, eyes locked on whoever’s filming, slow deepthroat action. Later, she’s lying back legs spread, painted toes flexing while she fingers herself. One of the dudes rolls a blunt on a desk, close-up of the grinder and papers—real chill vibe before the next round. Last shot’s a blonde MILF negotiating with two older white guys in an office, but the main heat’s the Black GF and her three-man rotation.
