My step son is coming home from university after a while. The backstory is step mom already has sex with her step son. step Dad knows. I it is not "taboo" in our family, nothing strange or abnormal, step mom is essentially step sons "Girlfriend". That type of relationship. I'm not just "step mom", I'm his "step mommy". Both of us caress each other, he put his hands under my dress & up my skirt, fingers in my mouth not a problem! I talk about how he spent his time, if he got a chance to watch all the vids & pics I sent him & if he only came on pictures of step mommy. Over the course of the scene, I get more & more suspicious my step son is cheating on me with another girl, he’s not calling me step mommy, the smell of his cock is different, the taste is off. It's no longer just step mom’s pussy, where his cum belongs!
