Up for a challenge? get ready ;) You have exactly 100 strokes to cum. Your goal is to cum EXACTLY on the 100th stroke, NOT before, and NOT after. So I'm gonna count from 1 to 100, and you're gonna stroke each time one, two, three, four, etc., whatever pace I count at is the pace you have to stroke at. No cheating ;) If you cum before the 100th stroke, not only will you have to ruin your orgasm by letting go of your cock when you cum so the cum would dribble down your cock, but, every stroke that you are early is one day that you're not allowed to cum (so if you cum on the 90th stroke, that's 10 days that you're not allowed to cum). If you don't manage to cum on the 100th stroke, too bad, you're not allowed to cum today. Come back and try again tomorrow. ready??
