I am 37m she is 35. I have always had a crush on my sister since we were teenagers. I used to take her dirty panties and sniff them to fuel my imagination.

One day I was browsing porn and looking at the site Suicide Girls. My sister's picture showed up and I was completely taken by surprise. She was sexier than I had imagined. I looked at her nude pictures for hours.

To this day almost 16 years later I am still looking at her pictures and getting off to them. I have complex fantasies of her treating me like a cuck. I have shared pictures of her with guys and let them fuck me while they look at her pictures and call me by her name. I even had one girlfriend that knew how I felt and she always role played as my sister. That was the best sex I ever had.
