Kareki hates his new step mom and step sisters. These bitches have no place in his house, let alone a part of his inheritance money. Fuck that. And fuck going to court. What they need is a good dicking - of the rape variety.
Marina and Airi's single mother has recently gotten married. Their new step-dad seems like he'll make a loving father. Like a really, really loving father.
Karen and Mizuki are magical Utea girls who protect the world from evil aliens. How do they go about doing that? By letting the beasts fuck their brains out of course!
