For starters, I expect you to be constantly stroking your cock from now on, only stopping if you're gonna cum, and even then only just for a bit. I want you to stay as close to the edge as possible, nonstop. You'll probably have to do super slow, super light strokes once you get real close.
It's an art. I expect you'll become quite practiced! The closer you can keep to the edge, the better - you should be seeing new precum at the tip of your cock every few minutes. Which you'll be promptly licking up, by the way.
