Mistresses Michelle and Lydia take the training of slave 47 up a notch by using their electric shock box on his cock and balls. Bound in a straitjacket, the poor slave is helpless as the Mistresses turn the intensity knob on the box higher and higher, laughing as they inflict more and more pain on his helpless genitals. They want to make sure he learns his lesson: his cock and balls belong to the Mistresses of Club Dom, to use and as they see fit.
