It's Not Cheating If It's In The Ass

My stepmom is always on my back, “clean this” “clean that”, but I don’t understand why she needs my help so badly. I have more important things to do, like masturbating, so I usually ignore her and focus on myself, but today she found a way to get to me. She walked into my room when I was jerking off, and before I could put my dick away she said “If you help me clean, I’ll help you with that”. No way that's going to happen. Of course, I masturbate thinking about her all the time; her body is smoking hot and she always wears those tight dresses that show off half of her ass around me, but I don’t want her to cheat on my dad. “It’s not cheating because I’m not gonna have you fuck me in my pussy, I’m gonna have you fuck me in my ass.” I know that logic is off, but so is her dress, and there is no chance I'm saying no to that hot booty and that sexy g-string. I'm going to clean this house as if my life depends on it, and I’m going to make my reward worth it.
