You don't know me but I'm about to become the most important person in your life: your keyholder.
You're going to put your cock in a chastity cage because I tell you to.
I may let you out one day.
I may never.
It's my decision and you will accept that.
You're going to do this because deep down you know it's right and proper. I'm your superior in every way and I have the right to decide if and when you will ever have access to your penis again.
Welcome to the rest of your life. It's going to be frustrating, tortuous, and wonderful.
You'll thank me for it every day.
