Professor Of Sex Ed (1973)

The scene opens with a curvy brunette with long brown hair already sitting topless on a guy’s lap in a dim living room. She’s got big tits and a thick waist, leaning back against his chest while he gropes her. They transition to a bedroom where she drops to her knees and gives him a slow, deepthroat blowjob — you see every inch of cock disappearing into her mouth. Later, she rides him in bed, bouncing hard with her tits swinging, while another woman watches or steps in for hand stuff. The camera stays tight on the action, lots of close-ups on lips, hands, and skin. Lighting stays low, giving it that tutorial vibe — like an actual sex ed class you wouldn’t survive in high school.
