Restrained to the medical bed, the patient of Mistress Euryale is wearing orthopedic braces: neck brace and spinal brace - not allowing to see what Euryale is preparing for him. Her collection of stainless steel dilators has been displayed next to the bed: picking up the first one in her latex-gloved hands, Euryale will use it as a warm up for the next step. Slowly first, she will dig into his urethra with 2 Hegar dilators, before she connects several electrodes and one electro-sound to her e-stim unit. Her patient delivers an immediate response, screaming loudly and hysterically, penetrated and electrocuted by the long and cold e-stim sound. Not interested in his discomfort, Euryale will keep increasing the power of the unit, testing how much electricity her patient can take inside his cock. His urethra will get dilated and electrocuted non stop, deeper and faster, while Euryale enjoys the view of her patient in agony. His mouth already maintained wide open by a metal gag is even easier to fill with her spits.
