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.
Once you discovered your best friends mom's big secret, you were able to blackmail her into doing everything to you. She was shy at first but now really takes control when she fucks you.
My friend asked me if i could help him get him my mom, i just told her hes a really good masseur and that she really needs a massage, he has been fucking her everyday ever since.
