There was a story posted (not here) by Laura Davis (sometimes known as Laura Lynn or Laura Lynn Davis), titled, "The Enema."
In the story, a woman's middle-school aged (or so) daughter encourages her mom to go on a date with her teacher. The date turns into a Dom/sub encounter where the teacher takes the mom home to the teacher's house, gives her an enema and then starts f**king her. The mom says they can't let her daughter know, whereupon the teacher calls the daughter into the room, and the daughter is both nude and collared. The mom ends up eating her daughter as she acknowledges her slavehood to herself.
This was a totally hot story, but was taken down sometime in the early 2000s, and I've never been able to locate a copy. It's also one that almost begged for a sequel.
Laura Davis wrote a slew of hot lesbian D/s stories, but this was one of the best of them imho. Anyone know where I can find it? Or better yet, anyone have a copy?
