If you didn't see the titles of Chapters 4 and 6, there is NTR involved this series. You have been warned.

In answer to @HDM1 and a general notice for future readers, it's not actually NTR. It's netori which is cucking others as opposed to NTR which is being cucked. so NTR haters can safely read this.

Chapter 8's some pretty creepy father daughter incest though
