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.
Bully: I told you to stay away from my girlfriend's pussy (your mom) or you'll get punished. Your mom fucked your toothbrush and said she's gonna spank you if you don't brush your teeth as well. Either way you lose. Such is the life of a wimp.
Your mom went to talk to your bully's dad about his son but ended becoming their family whore, look how she sucks him off as your bully fucks her pussy.
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
