Ah, but what a way to go!
Here's just some movies based on these sexual demons.
The Incubus (1982)
A supernatural source is discovered to be behind a series of violent sex crimes in a small town. I really liked this one, but that era of movies were just totally cool and it has this awesome sexy and scary music.
"Succubus: Hell Bent"
Sometimes what happens at Spring Break doesn't stay at Spring Break... it follows you home.
"Incubus" (2006)
Stranded after a car accident, a medical school student and her friends try to find shelter - only to cross paths with a deranged killer.
Okay, I know y'all are thinking--yeah, but where's the SEX? Here you go--
Succubus XXX
A mind-blowing, erotic horror, Evil Motion's Succubus stars Raven Riley and Liz Vicious as good and evil adversaries whose origin stems from a very ancient tale. Lilith (Liz Vicious), the fabled first wife of Adam, has been awoken from her slumber with a renewed lust for blood. Due to her defiance of God, Lilith was damned to eternal punishment by having to walk the Earth as a succubus demon feeding on the strength and lust of innocent people. Legend tells that only the eldest daughter in the bloodline of Eve herself has the power to stop Lilith. That chosen one is Raven Riley. She is the one who bears the mark and she will not be able to come to peace until she has slain the succubus.
