Looking for an old story

[ihhb]

So I vaguely remember a story from awhile back, and I'm trying to find it again, if anyone could help.

A girl in collage starts getting constantly aroused, realizes that her breasts are growing, and essentially decides to leave her old life behind to become a specialty prostitute (maybe in Vegas?) and have sex all the time. She ends up so big she can't move and when she's off the clock she does her coworkers

It sucks when old hard drives crap out, I'm sure I had it on my dead external...

Anyway, thanks in advance.
