Then about a month ago my father in law said that Jean in a silly way fancied me and that they have talked about what it would be like to have sex tog...ther, I was shocked but a little turned on, I said that sounds great and left it at that. Two weeks ago Tom my father in law said would I like to call round one afternoon while Ann was at work and have a little fun.I called round on Tuesday afternoon and there was Tom and Jean we had a cup of tea then Tom said that he wanted to stay and watch. Lifting my hands from my sides, Bonnie moved them to her boobs, craving attention: "Come on Steven, show this filthy slut what a man you are."Moulding purposefully, I soon had her moaning lasciviously, tits squirming in my palms. With a sure touch, I squeezed them together, fingers reflexing around the oversized mounds. "Oh baby, you have such greats tits," I enthused, nibbling an earlobe before my eyes were drawn back to the screen.The moment the music began and they burst into dance, I was. I’ve had my experiences with guys who try to control me and it usually never worked. But this man had some kind of power over me. Some kind of magic that had me slipping under the table. I unbuckled his belt and unzipped his fly. I reached into his shorts and removed his engorged cock. I ran my thumb over the bulbous head, catching the drop of pre-cum and smoothing it around the head. I could barely get my hand around the girth. Leaning forward from my knees, I wet my lips and took his large. I didn’t know what my sister was about to suggest, but I could tell it would be perverse. Sure enough…“I just licked your pussy to help you relax, sort of like a warmup,” explained Candi. “Plus, I’m a cat. I like pussy.”The joke was so unexpected that I couldn’t help laughing. It helped me relax, and I was able to think clearly for what felt like the first time in ages. Though incest—and bestiality—was both illegal and wrong, I was determined to activating my shifting gene. I had come too far.
