I love the incest genre as a fantasy. I have two sisters who I have no attraction to, and I do not want to screw my own mother. My favorite form of incest is brother/sister. For some reason the transition of family to lover just turns my gears. I have often thought about why I found it so attractive, and one thing that happened in my life sticks out to me as the reason I am attracted to this. I am a twin, but my sister passed away at birth. When my parents told me about it I was around 12, and just beginning to bud sexually. Knowing that I could have had a twin really messed me up, I had always wanted a twin, and felt lonely even when I was around friends and family. It was weird but I think I always kind of knew that I had one. Anyway I started watching porn pretty soon after that and eventually stumbled upon some hentai that involved twincest. I still am ashamed about it, but it helped to get my rocks off to it, somehow relieved some of the pain I had. From then on brother/sister porn has always been my go to. I honestly don't like mother/son much cousin is also something I enjoy. A bit weird but that is my own take on it.
