The Coming of Sin (1978)

One of the girls has a tight pink bikini on, the other’s down to black lace panties — they’re grinding against each other in front of a foggy mirror, hands all over. The lighting’s dim, just candles flickering on their faces and bodies as they take turns going down on each other. You get clear shots of tongue action, fingers pulling lips apart, and some deep thigh riding where one of them arches her back hard. It’s slow but filthy, no rush, lots of moaning and eye contact. The camera stays close, almost like POV at times — you see every twitch, every wet drag of skin. Feels more personal than most studio stuff, like it was shot for maximum intimacy instead of angles.
