If you want to jack off for me, you will respect and obey my methods. If you want to cum for me, you'll cum exactly when I tell you to cum, whether I deny you or drain your balls until they shrivel.

It's time to fix your worn out broken dick and retrain you. If you're going to be a masturbation addict, you will be MY masturbation addict.

This might seem a bit extreme at first, but it's exactly what you need.
