I Make My Step-mom My Submissive Little Slut

Ever since I started staying with my step-parents again after finishing college I have come to realize something that is very apparent. My step-mom NEVER CUMS. She is a great actress, I will give her that, but you can tell it isn't the real deal. Her husband (my step-father) is a great guy, don't get me wrong, but he is just not the kind of cock smith that can leave a woman with a leg shaking sopping wet orgasm. I can't decide if it's more hilarious that I can hear them trying to replicate the sex life I bring home or more pitiful that it has gotten that desperate. One day I come home early from work to find my step-mother on the couch getting herself off. This starts the spur of the moment rollercoaster that is, convincing her that she needs a real man, becoming her daddy, making her my slut, and my step-dad becoming her unknowing cuckold; ALL IN ONE GO. I knew she needed a real man to make her cum, and she fell into the submissive slut role almost instantaneously.
