Le Sexe qui parle II (1978) (Better Quality)
This one’s all about a slim blonde teen giving a detailed blowjob in what looks like a workshop or lab. The guy’s just standing there, but the camera gets right in, showing every detail. The lighting’s bright and clear, making it feel almost clinical. She’s got long straight hair, and the way she’s working it makes it obvious she’s done this before. The POV angle really lets you see her technique. At one point, she looks up, making eye contact with the camera — nice touch.
