You want to stroke. You have an instinctive need to stroke when I'm in front of you like this, but. You know better. You know you must wait for my permission. So properly trained that if you where to stroke without my blessing, it wouldn't even feel good. You may go ahead and rub it for now. Rub it in desperation as I tease you with my power. No cupping your hand. No stroking. Just teasing it ever so slightly. If you want to cum, or even stroke you will need to beg and convince me to do so.
