I must admit the best sex I have ever enjoyed with my wife was the night she lost her first arranged catfight. She had, had three fights up to this particular night and fought against an opponent who was unbeaten in four fights. One of the unbeaten cougars were going to lose their unbeaten records, the anticipation and turn on factor had me rock hard well before the fight began. After a fairly vicious encounter my wife ended up being worn down and beaten, unable to continue and forced to submit to the better woman, she hated it. This was the first time I had seen a woman dominate and beat my wife, she felt embarrassed at being beaten in front of me, sex was out of this world for me knowing she did her best in front of me but was beaten by a better woman.
Whether I now want her to win or lose, depends on what her opponent looks like, superficial I know, some I want her to beat and others I want her to lose against, comes down to the turn on factor at the time. That being said, it quite often doesn't work out how I'd like it to, opponents I want her to lose against she beats, and some I want her to beat she loses against, it's the anticipation of the unknown outcome that makes catfighting exciting.
