Golden Century of Porn 2 (1976) (Better Quality)

A slim brunette in a white coat plays patient in a fake medical exam, lying on the table with her legs spread while a muscular doctor checks her out. It doesn’t take long before his hands are down her panties and the exam turns into full-on sex. They move to a bedroom with red lighting where she rides him slow at first, then takes it hard from behind in doggy style. She goes deep on the blowjob, looks like she’s actually trying to choke herself on his dick. Later, he jerks off on camera in close-up, two separate shots showing him stroking and cumming. The whole thing has that raw, low-budget cam-film vibe but with better lighting and tighter shots than most.
