Kawane Kurumi trains her wife's daughter in a meat toilet

After being laid off, my stepfather changes suddenly and forces my mother to have violent sex. The father-in-law's poisonous fangs, which have become so tasty, attacks his daughter. While holding back for the sake of her beloved mother, the daughter ends up doing what her cruel father-in-law says, and before she knows it, she falls into the numerous obscene plays that surpass her imagination, and begins to want to do so, and ends up begging for her to impregnate her father-in-law's child.
