I sit my step-daughter down and tell her I am now having a romantic relationship with her step-brother, my step-son. She gets to watch while he eats my pussy and fucks me infront of her (implied), I can tell she likes this, it's no wonder she is my step-daughter. He gives step-mommy a big creampie and she eats it out of me like a good little Cuckquean step-daughter!
