Man you can talk about being open minded and shit, but it ain't fricking normal (in my defintion of what's the norm) for a Father to be plotting on ways to start an incest relationship with his own daugther... or for a son to be plotting on ways to sleep with his Mom and his aunt at the same time... or for brothers to have relations with their sisters and get them pregnant.
This is some sick shit and saltynuts you're mad angry scientist.
