Last weekend, I had sex with my step daughter. I know she's not that old. But I know she's only been with one guy. We've talked about it at length. I know her history, and her background and her past.

We never really talked about it until it happened. Just one night when I was at the house with her, my son was with his grandparents, and my wife was at work, we got into talking, and I just outright asked her if she had ever had interest. She said yes.

I used a condom. The sex lasted about an hour, because there was some foreplay, some kissing involved, and some oral as well. She let me go down on her, telling me a guy had never done that before. I made her cum a couple of times, between using my fingers and doing oral on her.

And when I came, I did it in a condom. When we finished, we talked for a long time, and she told me she liked being with me, and hoped that we'd do it again.

It hasn't happened again yet, as her mom and my son have been home every evening, but they're gone this weekend, and we've already talked about it. Yes. I know it's "wrong" considering the huge age difference, but it felt so good I want to again.
