Metronome JOI

Today were going to play a game. I will check how good trained you are. Youll stroke along to the pace of my metronome, while I am teasing you with my tight body in this lingerie. Whatever tempo I set will determine the speed of your strokes. I will be toying with you as always.Youll have to keep up no matter what. If I want you to stroke slower or faster you will do exactly as I said. What about your orgasm? You will find out in the end. Its not about your pleasure, its all about my fun, but maybe you will be lucky to have my permission :)
