O Lago Maldito (1977)

Starts with three dudes in full priest gear—dark hair, trimmed, average build—shaking hands with a slim brunette in a dress. You can see the tension right away, like they’re about to break some serious rules. The lighting’s dim, all shadows and curtains, like a church office or some old parlor. Then it cuts to a close-up of one guy’s stubbly face, looking all intense, like he’s about to lose it. Later, there’s a weird medical scene where the girl’s in a nurse outfit, bending over one of the guys in a lab coat—total roleplay, but the way she’s touching him, you know where it’s headed. The best part? The ritual vibes—three guys in tribal-looking robes, posing like they’re about to summon something, but it’s just foreplay for the main event. She ends up riding one of them hard while the others watch, then switches to doggy style on a bed. The camera work’s solid, gets right in there for the close-ups, especially when she’s sucking dick or getting pounded from behind. No fluff, just straight-up fucking with a creepy-church twist.
