my step sister caught mommy talking to a divorce lawyer and promised not to tell her father as long as mommy did whatever she wanted.
This meant that my step sister was going to do horrible things to mommy and make me watch(since she hated me.)
The demands started timid but started to get more and more cruel. every time my step sister pulls the card it ends with her cumming on my mommy’s face.
My step sister’s favorite thing to do to mommy is make her strip naked in front of me. Then she makes mommy lick her asshole. The whole thing is so humiliating.
