It's challenge time for jerker boy! Are you eager to earn that orgasm today? First, you'll have to complete an intense masturbatory feat. Look down at your cock. You'll only be allowed to stimulate one little bit of that throbbing, horny thing today. And the rest? Every part of your cock that I relegate to the forbidden zone will be denied even a single glancing graze of your hand. Now, this isn't a game of trust. There's no way you'll be able to keep your hand in place and refrain from reaching into the forbidden zone when you're worked up and in the moment. So I'll ensure that you can't trespass even if you try. You'll be constructing a little homemade cock controlling device under my command.  But that's not all. I'll be adding another element of control: a timer. If you don't succeed in exploding before the timer rings out, you'll enter the penalty phase...
