We are going to play a little game. The prize is an orgasm, and the rules are very simple: You will stroke when I say start. You will halt when I say stop. At any moment, I may begin counting down from ten. If you can reach orgasm by the time I reach zero, you win! So, it's in your best interest to ride that edge as much as you can. If you fail to cum when I give you the opportunity, you'll find yourself with a very uncomfortable pair of blue balls for the rest of the evening.... Good luck.
