This is simple, even a wastrel like you should be able to follow my rules. There is going to be a timer, once the timer starts you can start jerking. When time runs out, you cum! You can only cum when the timer is at zero, not a moment earlier. I'll, of course, be here teasing you the whole time, making it difficult for you to hold onto that load. I think I'm being more than fair.
