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.
Ayame and her sister know that their dad's been lonely ever since their mom left home. Like any good daughter, they just want their dad to be happy and help in any way possible. And we do mean, Any. Way. Possible.
