“Shockings are good” Princess Sara tells this slave, and the way she will convince him is with the pain and reward principal. She will shock his cock until he falls to the floor in pain, and then he is permitted to worship her feet. In that way he learns that having his cock shocked is good because it means he gets a reward. Princess Kendall loves this training as well as she shocks his cock repeatedly and then grants him permission to adore her feet. Good slave, with such repeated shock/reward training he will indeed learn that having his cock electrocuted is a good thing.
