Tricky Countdown Edging

You love some naughty countdowns. Hanging on my every word, you never quite know whats expected of you, but youre desperate to keep up, because its your orgasm on the line. The countdowns I give today come with special consequences, with penalties for not being on the edge when I command it, AND for getting there too soon. You really have your orgasm control tested. How much can that cock take?
