Incestuous Sex

I met my father when I was 38, and my youngest sister who was 26 was sexually attracted to me. I resisted at first because we are siblings until one night at my father's house my sister just pulls out my dick, I was shocked and turned on too, it felt weird. She I just want it one time I gave in. She gave me some of the best head I've had and her pussy felt amazing. I told myself this is the only time but it wasn't so we proceeded to fuck like rabbits and she now is in love with me and I love fucking her in every way and hole. I still feel conflicted because she is one of the fucks I've had but she is my sister. I done came in her delicious pussy fucked her ass and she loved every minute.
