Murder Obsession (1981)

Alright, so this one’s got a weird-ass vibe but it’s actually pretty hot. Starts off in some creepy mansion with a bunch of chicks in vintage dresses and dudes just chilling—no sex yet, just suspense. Then you get this brunette in a robe holding a knife like she’s about to go full psycho, which, honestly, gets me going. Later, it’s all skeletons and foggy woods, but don’t worry, the sex part delivers. The main girl—slim, long wavy brunette—ends up getting fucked hard in some dark room, and the lighting’s dim but you still see everything. The dude’s not huge but he knows how to use it, and she’s into it, moaning like she’s actually feeling it. The whole murder obsession thing is just set dressing, but it works—gives it a kinky edge without going full horror. Camera’s solid, not too shaky, and you get a good look at her tits bouncing when she’s on top.
