La dernière femme (1976)

The black woman in her 20s has short dark hair and a slim, toned body — she’s wearing a tight black outfit early on but loses it fast. One guy is white, 20s, curly blonde hair, slim, shirtless with a red tracksuit bottom, confronting another guy in a bedroom before things turn sexual. They end up in a messy threesome in the living room, all on a couch — she gives one guy a blowjob while the other eats her out, then switches to riding the blonde guy facing away, deep doggy-style thrusting with visible bounce. Camera stays wide in most shots, capturing the whole setting — bedroom, living room, even a suitcase and handbag left around like they just arrived. The second guy, dark-haired and short, gets facial cum after she jerks him off leaning against a wall in the apartment. Lighting stays dim throughout, mostly lamp and ambient, gives it a late-night, private vibe.
