Erotic Nights of the Living Dead (1980)

Starts with two slim girls on a beach — one blonde with long straight hair and a tight tan body, the other a brunette with waves. They’re all over each other, hands everywhere, before the scene cuts to a bedroom. The blonde’s on all fours, getting railed from behind by some inked-up dude with nipple piercings. He’s got a good grip on her hips, really slamming into her, and the camera’s right there so you see everything. Later, there’s a masked guy in the mix, all muscle and shadows, looking like he’s about to take over. The lighting’s dim but you still get a clear shot of the action — no blurry shit. If you like zombie stuff mixed with hardcore fucking, this one delivers.
