I'm not talking about Carrie or Teen Witch. (I Googled this description and all I got was Carrie and Teen Witch.
) I'm asking about an 80s (maybe early 90s) movie where a father and daughter move to a new house (I can't remember if there were other siblings) and the father meets a new girlfriend. The girlfriend turns out to be a witch and does rituals (with black feathers?). Well, there are feathers involved somehow... Also, during one of the witchcraft/sexual rituals that the new girlfriend is doing with the father (unbeknownst to him), the daughter has her period at school. Anybody have a clue as to what movie this might be?
