Flirt Dangereux (1981)

One of the girls has short dark hair and red nails, on her knees sucking a guy with no hesitation — deep throat action, you can tell he’s into it by how he’s gripping the bed. She switches to the other girl, both of them eating each other out in missionary with lots of close-ups on the faces and tongues. Then the third player comes in — a muscular guy with dark curly hair, gets tied up with ropes while both girls take turns riding him and going doggy style. The brunette stays dominant, pushing the blonde’s head down for a double blowjob at one point. Most of it happens in the bedroom under dim light, but there’s a clean wide shot of all three naked in the living room earlier, posing near a bookshelf like it’s some kind of intro. The gangbang gets messy, lots of skin slapping, switching positions, and facial at the end.
