Wannabe Witch

My sister Glenda 23 is a wannabe witch and all things in the realms of the occult. I found a really old book in an old book shop
called Liberfamias in Maleficiis Suis, I hope it's spell right as the name was very hard to read. I was told it is Latin for witchcraft chronicle. Lucky its text was in English and it had 13 chapters and the last page of some of these chapters is only a sentence or two to a half-page. With a lot of pages loose in the book, I decide to play a joke on Glenda and see how far she was willing to go to become a witch. Using cut and paste I added an extra line at the end of these Chapters and trial and error in the printing on copies of these pages before printing onto the original pages. On the first page, I added too How to become a more Powerful Witch. Fratrem Sexus. That's all and later on another page Fratrem Sexus with the symbol of power the triple horn of Odin. With triple horn symbol used, again and again, I kept hinting that Fratrem Sexus was the only way to become a powerful and on the last page I added 13 times Fratrem Sexus. It took a while but I finally had it all completed and took the book and had the loose pages reattached by a bookbinder. Then I gave the book to Glenda and left her to read it. I waited to see what she would do, nothing it seemed at first. Then she asked me what Fratrem Sexus meant I said I didn't know it was Greek to me and added maybe Latin. It was several days later I saw her again and she was read the book I had given her and asked her had she learned anything from it or was it all rubbish like the other books she had. She replied she had somethings and was still working through other things. Then she asked me what I thought Sexus meant in Latin, I answered wasn't he a Roman poet. No, she answered it Latin for sex, good to know if I run into a Roman woman and left. Then she rang me and asked if I would help her out, I said okay now or later. On the night of the full moon, she said. Alright when is that I asked in three days' time and we will have to be at the family cabin at the lake. Why I asked for the rituals she replied, I thought she was having me on and just said alright. Then on the afternoon before the night of the full moon, I met Glenda and we headed off to the cabin. I unpack our stuff and Glenda walked about with a compass and marked a few trees. She didn't say anything and I went down to the lake to see if I could catch a fish. I didn't but it helps pass the time Glenda made dinner and after as the moon rose in the sky she changed into a sheer black dress which I almost saw straight through. What the Rituals I asked, she answered Fratrem Sexus, what's that I asked trying to act like I didn't know. It will make me a powerful witch she said. No sacrifices I hope I replied. No, not that type ritual she answered. Then as it got close to midnight she said it was almost time and she led me outside to where she had prepared the ritual site. She lit candles in glass jars of different colors and in the shape of a pentagram and in the middle was matress. I asked what do you want me to do, she looked at me and said I want you to fuck me. I was shocked at first and thought she was trying to trick me and then asked why me. Fratrem Sexus is Family or Sibling sex and if I want to be more powerful as a witch I must have sex with a close relative. Yeah, right I said what happens if you don't get more powerful as a witch. I just get fucked by you and I'm will keep trying to improve myself. I decided to call her bluff still thinking she was having me on. Then she stripped off her clothes and was totally naked before me and my cock went hard as a rock and I had let it out of my pants. So I stripped off also thinking she would back down, but she laid down on the mattress and invited me to join her and I did and I started to feel her up and she started to play with cock. Then she said it is time and wanted me to mount her and I did and I fucked her as hard as I could and after I had cum inside and rolled beside her. I asked do you feel more powerful, no but it is only the first time. After a rest, we started again and by morning I had fucked her 3 times. We stayed a couple of more days and she drained my balls every day. She didn't get more powerful, but she did get pregnant. The baby girl is due in the new year and Glenda thinks she will have the power of the ritual I'm still fucking Glenda.
