Les jouisseuses de Hong-kong (1981)

A blonde in her 20s with long hair and a tight, curvy frame gets fucked on a rocky beach, lying on a towel while waves crash nearby. She’s first seen jerking off alone, then a short-haired brunette joins her — slim, muscular, brown-haired — and they go at it with grinding and heavy kissing. They move indoors to a dimly lit room where the brunette gives a rough blowjob, face deep in the blonde’s pussy, then gets flipped into doggy on a chair. The blonde rides her hard after that, long hair swinging, sweat visible under low light. Camera stays wide for the outdoor shots, capturing the rugged shoreline, then tight and shaky during the indoor action. The creampie at the end is messy, thick, and clearly shot in one take.
