The Mitchell family welcomes a new family to their Los Angeles neighborhood, only to discover they are evangelical Christians, which poses a problem for their incestuous lifestyle.

This story is darker than my past ones, including rape, torture, and non-consensual sex (but there's lots of joyous, consensual sex too). / (Reviews)

Pretty soon there was incontrovertible proof that I thought she was already sexy. It was embarrassing. Then she wanted to SEE the proof and things just got weirder from there.
