Mom is sneaking around and cheating on her ill husband with three older brothers. Her son thinks he's gay and is fucking the same men. Things go wild when they learn the truth.
Two, 14 year old brothers, work to enslave their mother, having only S&M, dirty books to guide them. This story is a fan prequel to Kathy Andrews' book, "Chained and Spanked Sister". [WARNING - Chapter 4 contains water sports. It's the only chapter that goes into detail about it. Not really my thing, but it brings important continuity to Kathy Andrew's original story.]
