"I've come across some neat stories where a mother pimps her daughter for some reason or another (debt, job complications, blackmail, etc.)"

"The second common motif is where the mother pimps or pro-offers the daughter for some reason. A psychologically valid one would be the abusive step-father figure: Mom overlooks, consciously allows, or even pro-offers the daughter to keep her husband satisfied."

Can you point me in the direction of some stories that fit into either of these molds? I've been fantasizing about a scenario like this for YEARS now....
