Looking for a story

[cockfightdude]

I am looking for a story I read on here a while ago.  It took place in a nightclub toilets was a sexfight between two rivals in a cubicle who had a score to settle from before.  Was quite violent and incredibly hot.  Seem to think one of the two was a red head but cannot remember more than that just that I loved it and can't for the life of me remember the title to find it.

Any ideas!?
