I am waiting for my step-son to hurry home from school. He wears a remote ball shocker under his chastity so I can shock him any time I need him to come and service me. As I grow more impatient, I press the shocker more. Finally, he comes home crying in pain. I do not care that he had to leave in the middle of a test. I don't care if he fails. He needs to prepare my asshole for a date and I'm gassy, so he needs to suck out the farts so my boyfriend doesn't smell them. My step-son has no choice. I lie him down and smther him under my huge ass. I fart relentlessly in his mouth and nose while berating his negative attitude. I shake my ass and tease the locked up boy, turning around and spreading my pussy that's about to be fucked and filled with cum. My loser step-son will be a virgin for life. He is going to be my date prep bitch and clean me up when I get back too!
