Alucarda, la hija de las tinieblas (1977)

Alucarda, a slim brunette with long wavy hair and a pierced nipple dripping blood, is the focus here. She’s going at it with another young woman in what looks like a creepy ceremonial space — fire pits, skulls hanging, red lighting, the whole gothic thing. Close-ups show her taking a blowjob from a dark-haired girl with short hair, both fully into the weird energy. The sex is rough and intimate, lots of face shots during oral, and that blood detail adds an unsettling edge. One wide shot shows them standing in a room with a hooded figure in the background, not doing anything sexual but adding to the ritual vibe. Camera stays tight during the action, focusing on faces and breasts, with a greenish or fiery tint depending on the scene.
