I'm looking for a story that probably only people hanging around here would know.

Years ago I've read a story that went something like this: In opening scene there is a teen girl going to the toilet, but instead of sitting she leans over and milks the piss out of her nipples. Then it is explained how her mother forced her to get urethral reroute to her breasts, etc.

I'm pretty sure it was posted on sexstories.com but now i can't find it anywhere.
I don't remember the title or author so I can't effectively search or be sure it was deleted.
