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.]
A woman grows up in an very permissive household and following her first introduction to sex with her brothers and parents devotes her life to sexual gratification of the most perverted kind.
