I love my wife, I really do, but her daughter has been turning me on since before she was legal. So when she came to visit this summer, finally 18 and perfect in every way I knew what I was going to have to do. I was thinking with only one head, the only one that matters in these situations. I did not care that she was my step-daughter, just that she was young and tight and had tits that give men a hard on when she is just walking by. The fact that she usually stayed with her dad made it easier on me, or I would have lived with a boner for the past two years. Her mom had been amazing in bed, in the beginning, but she was way too busy now with her business, too busy for me or her daughter this summer. Which worked in my favor.
It was on one of those lazy days the very first time. Too hot to be outside if you could help it. The wife left early and would not be home until long after dinner time, as usual. I was just sitting in my chair drinking a can of beer and watching a movie when the girl came in. She must have been out all night as she looked a little disheveled. Her ass hanging out of her skirt and her tits barely in her top. I asked her what her mom would say. She looked at me and asked what it would take for me to keep my mouth shut. My cock jumped to attention, this was the moment I had been waiting for. I walked over to her and looked her up and down, I told her I don't think she could handle what I wanted. The little minx looked me in the eye and said she could handle anything I could throw at her. With that I picked her up and tossed her over my shoulder. She squirmed against me but I only tightened my grip and slipped one hand up to her pussy, the thong she wore good for little but turning a man on even more. I could feel she was already wet, despite her protests.
