Looking for stories where a daughter dominates and humiliates her mother, essentially turning the mother in to a sex slave.
Things that would mmake it better:
* Story starts with mother noncosentual, but then she learns to love it.
* Teenage daughter (college freshman or even high school)
* Daughter starts sleeping with dad and cuckqueans mom
* Daughter shares mom with her brothers
* Daughter shares mother with dad's poker buddies, then the rest of the neighborhood.
