My darling girl, it's time to make a big change in your life. To gain control of you, it only makes sense for me to control your orgasms. Yet chastity doesn't seem to be enough for your case. I've decided to take control of your precious girl dick, in the most permanent, extreme way.

I'll be giving you a penectomy. Yes, darling, I'll be lopping off your girl cock, ensuring that you will not be pleasuring yourself without my permission. How frustrating that will be for you, not to mention painful as hell. I am going to slice and dice your way to freedom.
