Your bully acted like he's your friend infront of your mom. Two visits to your house and now he's fucking her after drinks. Everyone in school now knows that your mom spreads her pussy for him.
He can bend her over and fuck her pussy during a lecture. He can spank her ass coming into the classroom. He can even rip off her panties during lunch and lodge a buttplug up her ass. Doesn’t matter, he completely owns and dominates your fleshtoy of a mom
