I catch my stepson in the bathroom trying to install a hidden camera to spy on his cousin while I'm trying to pee. I tell him how disgusted I am with his behaviour. I notice that he's getting hard while watching me on the toilet. I make him remove his clothes so I can see. His cock is hard for me. I decide to teach him a lesson about spying so I strip my clothes off. My stepson can't resist looking at my ass and I tease him with it and make him stroke to my dirty ashole before asking him to join me in the bedroom where it's more comfortable. I continue to tease him and tell him jerk off to my ass and asshole. He finally cums all over my asshole and I let him know that if he ever spys on someone again I'll have to teach him another lesson.
