Le trio infernal (1974)

Starts with a slim blonde in a feathered hat leaning in real close to another girl in a train seat—lips almost touching, fur stole slipping off. Then two guys in suits show up, one holding luggage like he’s about to check in for a very different kind of ride. The blonde ends up kneeling on a plush rug, holding a leash attached to one of the guys—he’s got that “I own this” look while she stares up at him. Later, he drips hot wax on her stomach, slow and deliberate, like he’s savoring every second. The whole thing feels like a 1920s noir flick but with way more skin and kink. Good angles on the wax play and the leash tugging—no shaky cam, just tight shots of the action.
