Consultorio sexológico (1980)
A dark-haired guy with a mustache sits in an office chair, looking like some kind of therapist or doctor, wearing glasses and a button-down. Two women show up — one brunette with long hair, another with a tighter frame and short dark locks. The mood shifts fast from professional to sexual. First, the brunette gives him a blowjob right there in the office, slow and deep, then switches to riding him on the desk with her tits bouncing. The other girl jumps in, taking over in doggy style while he grabs her hips hard. Camera stays tight during the action, especially when they switch positions and she leans forward, ass up, getting pounded. Lighting stays soft and clinical, which makes the whole thing feel like a fantasy gone real.
