There's one rule above all others: you will only be able to wank your dick, when I give you permission. You won't ever touch it before I gave you the go! And because I have the key to your chastity device, I have the full control over your dick! You'll be buying all my clips that will tease you like hell, but you won't jerk off. All that you can do is begging and crying for some relief, but it's on me to control it.
