Superlady (1975)

Girl on her back, slim build, dark short hair, tattoo visible on her side, lying on a messy bed under warm lamp light. Guy kneels between her legs, short dark hair, muscular build, goes down on her first — tongue working slow, close-up shows her fingers gripping sheets. She grabs his dick, starts jerking him off with one hand while lying back, not rushing it. They switch to missionary, he’s fully inside her, deep thrusts, camera stays tight on their bodies moving together. Lighting stays low the whole time, gives it a private, almost voyeuristic feel. No talking, just the sounds of skin and breathing.
