The Las Vegas Strangler (1968)

Starts with this tiny brunette chick—dark bob, slim as hell, collarbone popping—jerking off on a chair in some sketchy motel room. The lighting’s all shadowy, like a 70s detective flick, and there’s a dog just chilling in the background, not giving a fuck. Then this dude in a checkered shirt shows up, leans in close like he’s about to drop bad news, but it’s just the start of some rough shit. She’s on the bed, looking all vulnerable in a nightgown, and he’s got that vibe like he’s about to wreck her. No soft-core cuddle stuff here—just straight-up choking, hard thrusts, and that dim lighting making everything look grittier. The camera work’s solid too, close enough to see the tension in her face when he’s really going at it. Feels like a crime scene meets porn, and the vintage setting sells it.
