Catfight at the Bottom's Up

Phil has been attending the monthly topless catfight shows at the Bottom's Up club for quite a while. He dreams of his beautiful wife Mari, engaging in a match with one of the female catfighter's, and eventually gains the courage to convince her to agree to it. One time only. At the Club Mari is slated to meet Serena, her husband's favorite catfighter. The prospect of this fight has him in a heightened state of arousal and fights to contain his emotions.
He is less interested in his wife Mari winning the match as he is seeing her rolling around nearly nude sweating and struggling with Serena. Mari, a true novice at catfighting, gets off to a shaky start and really takes her lumps in the first round. But Mari is a fast learner and equates herself admirably in the second round. Luck seems to smile on every move she makes in the ring. The third round ebbs and flows, and either girl could win.
Serena has Mari on the ropes, figuratively and literally, and tries to bring Mari to an explosive climax, but from that dark moment, but will Mari's luck hold out, can Mari snatch victory from the jaws of defeat?
