My Sister my Horny Witch

My sister 37 I'll Sabrina went a little strange after the death of her husband in early 2024. I'm 43 divorced and only relative living close to Sabrina. Sabrina cannot have children to ovarian cancer in her twenties. My children prefer their mother to me, so they rarely call or see me at all. I went to see Sabrina last Halloween, mainly to check on her as I was told she was acting strange. Using Halloween as a cover for dropping by, growing up it was a favorite celebration of ours. Dropped by on Tuesday the 29th, found her dressed in all black all her makeup was also black eyeliner, eye shadow, lipstick and nail polish. She a natural brunette, her clothes weren't very revealing unlike Elvira as they didn't hug her figure or being low cut. I did find out certain things; she had tried to contact her dead husband thru seances. Lost interest in that fairly quickly, had started going online to occult websites. One or two told her that modern occultism was corrupted by the churches over many years. But she found a so-called original book of course downloaded onto the internet. This took her interest; it claimed that thru rituals you can get extra powers. Different rituals for different powers, the one that took her interest was ability to contact the dead in the afterlife. It didn't require potions or weird rituals, just sex on special nights of the year like Halloween and Walpurgis night plus some others. But both involved had to be connected via something such as same belief or as in our case blood relationship. As she was having trouble finding someone of the same belief, I became her next best option. To say I was shocked when she straight asked was in my case overstating it a little. I was a little taken aback, but I love sex and that overcame my reservations almost instantly. But sex was to be only on the special nights no other nights, a plus was no limit on the sex had those nights. Of course, I refused not really, I thought I should but didn't actually say that I agreed. But not wanting to appear too over eager. I asked you just want a fuck on Halloween, she responded Yes, but more than just the once. I nodded couldn't believe my luck, also it turns out Christian celebrations such as Christmas are based on pagan celebrations. Just made holy by the church in the past. I turned up at 5pm on Halloween ready for sex, but she was ready to start straight away. Wanted to do the modern Halloween thing first. Not going trick or treating, just giving candy to children in the area who came to her door. After the candy was gone, then ritual cleaning started. Showering together and sensual massaging, then fucking my favorite part. We fucked three times before falling asleep together, I awoke early it was still dark outside, so I tried my luck she allowed me to fuck her again. Plans made for the next special night Christmas, every special night I get fucks from my sister. No extra powers gained by her yet, but it does say years of devotion in the occult belief she is following. So, I'm looking for years of regular sex with my sister the Witch.
