I'm sitting in my chair in some skimpy lingerie when I realize just how horny I am. I begin to rub my pussy through my panties. I hear a noise, I'm shocked to look up and see my stepson watching me. However I'm not mad. I know he's been spying on before. So I decide to have some fun with him. I let him watch as I continue to masturbate. I encourage him to touch himself while he watches me. That's it stepson, cum for StepMommy!
