The Key (1983) (Better Quality)
The guy in glasses sits back in his office chair while a woman goes deep on his cock — you see the rim of his glasses reflecting the dim light as he leans his head back. She’s taking it slow at first, mouth wide, one hand on his thigh, then picks up pace with her head bobbing steadily. Cut to a bedroom where two women are grinding on a bed facing a mirror — the one on top has long brown hair and a tight ass, the other’s got short gray hair and is pulling her own folds apart to watch the action. The lighting’s soft but clear enough to see juices on the lower girl’s thighs as the other rides up and down. Camera stays at medium range most of the time, no shaky close-ups, just steady shots that keep both faces and genitals in frame. The office scene comes back at the end with the guy finishing on the guy’s shirt and tie still on, pants around his ankles.
