Incest + Brother + Sister Stories

I'm a clinical psychologist whose quixotic goal is to become a screenwriter. Not that I'd give up my day job. I'd like to use my private consultation experience to create a Netflix-type of series. The seven case studies I describe here comprise an interesting subset of incest. Each one involves a mother who actively enables her son's sex life. IDs are disguised, but all the sexual activity did occur. I am required to report things such as child abuse. I alone define abuse.
