"I can see that you really do you need more training my dear" Luke said with an exasperated tone in his voice, "if you would have left your tongue in my ass hole and screamed, the vibrations would have provided me with exquisite pleasure, instead you chose to place your own needs over the pleasure of your Master. You must learn that your own desires, and wants are always second to the pleasure of your Master. Don't worry the electricity will do no permanent harm to you, since it is connected to your most intimate points it doesn't take much voltage to shock you, I have no desire to harm you, now let's try it again, get your tongue back up my ass hole, and next time you are shocked do not pull away, scream all that you want, concentrate on your Master's pleasure."
