This is one of my FAVOURITE forms of training for obedient, ballbusting subs. Step One: Understand that YOU are the only one who cares about your dick and that is your greatest weakness. Step Two: Acknowledge that my pleasure is far superior to yours. Step Three: Acknowledge that my greatest pleasure is finding your weakness and tormenting it. Step Four: Relocate your pleasure so that it aligns perfectly with mine, in your balls. This clip is an example of an obedient submissive who I've trained to orgasm by ball punching ALONE. I'm currently training him to forgo any dick stimulation at all with rougher and rougher ballbusting. Practice makes perfect and - OH YES - prolonged chastity ;) Stay tuned for Part 2!
