The Drawings by higurashika - Adult Sex Game

It is good to have a sister. You can share everything with her: your thoughts about s, dresses or feelings. But what if everything you knew is a lie? What if your school life won't be the same after some cruel event? Will you accept your lineage? Will you stay the same when your parents reveal their biggest secrets to you?

This is criminal story with sex and murders. Something in between Dexter and House of 1000 corpses.
