**JOI July 28 - Timed Masturbation Challenge**
Today is a timed challenge. You are only allowed to stroke when the timer is running. You get 30 seconds, then 20 seconds, then 10 seconds. You have to cum right at the end of the last 10 seconds. If you take too long, you don't get to cum today. If you cum before the time's up, you have to ruin it. Do you think you can make it in time?
