You are completely out of control. Guilt ridden and ashamed of yourself.
Your porn addiction and compulsive masturbation is ruining your life. That's why you need to cage that cock and let me take control.
I know what you need. You need guidance and training. Someone to answer to. A mature woman in authority. A teacher, a key holder.
This can be a very rewarding experience for both of us if we are a good fit.
Maybe you are new to the idea of chastity and would like to discuss the possibilities with a woman that understands or a seasoned device wearer who needs a long term key holder; I'd love to assist you through your journey.
That cock belongs to me now.
