I want to control your orgasm in a new way: you're going to use a vibrator to cum for me. I love having you tied up and teased at my mercy, while I tie up and tease your aching cock with a vibrator. We are going to replicate that today by me instructing you in exactly how I want you to tease your cock. Starting low, you'll tease it until it is just barely hard enough increasing the intensity until you empty your balls completely. Grab a vibrator and let me make you cum.
