His sister

You're enjoying a rimjob from your ex-abuser's mother and finally decide that you don't have to stand, instead you tell the slut's mother to lay her head up on the couch in a very uncomfortable position - let the slut do some gymnastics. You then sit on her face and tell her to continue licking your asshole, which she does. You sit comfortably on her face and turn on the TV.

While waiting for Zack's sister to come, you feel like you want to fart, so you fart right into the mouth of the slut licking your ass.

After a while, Ann, Zack's sister comes in and starts screaming when she sees what you are doing with her mother. She runs up to you and tries to pull you away from your mother but you touch her and tell her to calm down and then undress and then suck your cock while her mother continues licking your ass.

You laugh at the fate of these two whores and revel in the power you have over them. Now you're just waiting for Zack to show him how you treat his family, tell him what you did to his girlfriend, and destroy him too.
