The Metronome Game

Hi! I want to play a game. I want you to jerk your cock to the beat of my metronome. You have to jerk it to the same pace as the beats. If you mess up and cum early you will have to start the game all over again. With every round the metronome will speed up, making the game more challenging. If you are able to make it to the final round, you may cum. Good Luck!
