Wannabe Witch update

I tricked my sister Glenda into having sex with me, by adding the words Fratrem Sexus to an old occult book I found in an old book shop. It was called Liberfamias in Maleficiis Suis or something very similar. I was asked by Glenda to join her in a ritual at the family cabin on the night the full moon and we had sex. Glenda got pregnant and is having a baby girl soon we are going to call Sabina and I told Glenda of my deception. To my surprise she knew all along I had added the words Fratrem Sexus to the pages of the old book. But she said if I had bothered to read it myself, I would have known it was already mentioned in the book several times. She has me joining in her rituals with her and still lets me fuck her anytime I want. We are living together and Glenda wants to start a coven, she has started looking for women to join with us. I asked how many men she wants to join with us and she replied none. I'm to be the only male and she said I would have to fuck all female members of the coven. I'm okay with that, but the only new member so far is Annette 35 single overweight, but very willing. But Glenda is also trying to Janet 37 divorced no children our cousin interested in joining. She is slim and plain looking and we will need 2 more if Janet joins.
