All you knew is that your mom was going to confront your sister for dating your bully. Now you get a text from your sister telling you "Bro! Mom is lubing him up real nice for me."
Hey cuck, your gf says she's dumping you harder than I dumped my load in her. She's not even gonna be my girl, just a side hole for when I feel like using her like a bitch. Now come clean this mess up and send me your mom and sister
You walk into your girlfriends room to see her like this, when she is about to respond your bully shoves his cock down her throat and says "she's busy". She just moans in agreement
