You guys are amazing at finding stories based on sketchy memories, so here's one more. Read this online probably a decade ago, but don't remember where.

Ok, all I can remember of this one is that there's going to be a catfight or couple fight or family fight in a cage in front of an audience, but before the main event they're in the audience watching some earlier fight between two men (yes yes ewwwww...but us girls like reading about boys being destroyed too lol). One wore blue and one green (speedos?) if memory serves. aaaaand the loser gets his cock and balls chopped off by an attendant with a little guillotine thing. OK, you can uncross your legs now...

Unfortunately can't remember anything about the main fight except that it was good.

In short: blue and green speedo men fight, choppity chop chop one loses his penis, and mysterious big fight follows.

Any of you catfight savants know what this could be? Thanks in advance!
