Because my clinic specialises in electro-stim therapy of the cock and balls, Im confident that my pierced and clamped patient will soon be feeling the benefits of the multi-channel currents Ive now attached to his foreskin and scrotal sac. In this final part of my medical extravaganza I add some manual masturbation and extreme vibrations to the mix to test if his sexual responses have improved as a result of my painful, but necessary, medical treatments.
