House of Whipcord (1974)

The older guy has a bald head, pale skin, and some wrinkles around his eyes — he’s not in great shape but seems into it. One girl is blonde, slim with long hair, the other has dark brown hair and a tighter frame. They take turns sucking him off on a couch before flipping him over for doggy. The camera stays close during the blowjobs, you see every leak and gag. Later, the brunette rides him face to face while the blonde jerks him off from the side. Lighting’s low throughout, mostly shadows and skin tones, gives it a raw feel.
