Malabimba

After the matriarch of once rich and influential aristocratic Caroli family dies, her nearly bankrupt family decides to hold a seance in their decrepit castle and contact her spirit. Unfortunately, they contact instead the malicious and possibly demonic spirit of their evil, hedonistic and decadent late cousin Lucrezia that, after assaulting and messing a bit with those present at the summoning, ends up possessing the dead woman's virginal teenage daughter Bimba. Bimba suddenly becomes overtly sexual and starts acting out in a completely unhinged, aggressive and sexually provocative manner in front of her family and their guests, all while brutally insulting them. She tries to satisfy her confusing demonic urges with masturbation but quickly moves on to seducing those around her. (Vinegar Syndrome)
