They been friends for a while and they both enjoyed going to wrestling shows together. The one in the Left began a relationship with a guy who also enjoyed wrestling.
The one on the Right used to be a big girl, but she's lost a lot of weight and looks amazing and her boobs hold.
One day the one in the Left came home catch her boyfriend and her friend kissing while she was already on her panties and he had her on top of a counter. The one in the Left came in and quickly push him aside and drag "her friend" by the hair to the floor.
Who wins a last standing match?
