How to get back at your husband’s mistress?
Very simply!
Seduce her dad with your “matryoshkas”, marry him and become a shameless, vile, evil stepmother.
And it would be all fine, but her father is a real boor, a womanizer, and a fetishist.
Will I be able to cope with his wild parental temperament, or is it better to give up on my ridiculous plan?
