Sleazy Rider (1972)

This one starts with the blonde chick sitting in a bathtub, legs spread, fingers working herself over like she’s already past the point of no return. The lighting’s moody, all shadows and wet skin, and you can tell she’s not faking it—her face is all twisted up like she’s about to lose it. Then the dude with tattoos up his arms shows up, and things get real. He goes down on her first, slow at first but then gets rough, like he’s trying to eat her alive. She’s on her back, legs in the air, taking it like a champ. Later, he flips her over and fucks her from behind, gripping her hips hard enough to leave marks. The room’s got this weird green tint, like they’re filming in a basement or some cheap motel, but it works—adds to the sleazy vibe. No fancy editing, just raw, sweaty sex with a girl who clearly enjoys getting pounded.
