Having shaved, tied and separated my slave's now-smooth balls, Lady Annisa and I can start some internal treatment with an electrified sound slid deep into the patient's cock-shaft. While I control the breathing and medication, my colleague opens up his urethra and sends the current flowing to match the electricity now surging through an elasticated cock-ring on the outside of his penis. Trapped inside a heavy rubber body bag our patient can hardly complain: but why on Earth would he want to?
