Any other details you can think of, possibly author or characters names? Possible title?
Might try looking around at Bodyinflation.org's story archive. It's got a lot of the old LVKane pieces which you generally won't find at overflowingbra. Site loads a bit slow, though, and you don't get much beyond the title and author.
If you happen upon it there, though, please mention so here. You've caught my interest, and I don't recall hearing of this story before
