It began innocently, with lingering looks and gentle touches. As time passed, simple step-motherly affection for my step-son transformed into something far more intense. Now I find myself living two lives. I play the part of the devoted wife, but I have the secret life constantly at risk of being discovered. In that secret life that overtakes my every waking thought, I cannot resist the animalistic passion that I share with my step-son. Now just the thought of his thick cock stretching me instantly makes me wet. I actually feel guilty for having sex with my husband, seeing how jealous it makes my step-son. Any time I have sex with my husband out of obligation, my step-son makes sure I know it's his cock that I love having inside me. As if I could ever forget how much I love having him shoot his cum deep inside of me. Every day we steal moments to share this forbidden, sexy dance. We count down for the moments when his step-father will be busy or distracted. That is when my step-son will have his way with me, as if I could resist or even want to. We are getting more and more reckless and have had too many close calls. One time when his step-father was just in the other room, I nearly had my step-son's fat cock inside of me on the kitchen as I was making the table for dinner. His step-father walked in on us almost caught us. I was sure he could have seen how wet my pants were from how wet my step-son makes me. Admittedly, the thrill of nearly being caught in the act so many times adds to the intensity. Living this secret life has presented a new challenge. I know that I am pregnant, and I will HAVE to fuck his step-father tonight. That is the only way to protect this secret. And this secret makes me crave my step-son inside of me even more. As my belly grows, so does my need to have my step-son slide his gorgeous cock in my soaking wet pussy. I don't want any of this to change.
