A group of hulking, inked gay studs present themselves to a dominant doctor for a special kind of physical therapy. The doctor, a stern yet lustful man, runs his hands over the men's rippling muscles, preparing them for the electro-stimulation treatment. He starts with a beefy, bearded patient, attaching the electrodes to his nipples and running the machine, making the man gasp and buck against the table. The doctor's own cock tents his scrubs as he works, his eyes gleaming with desire as he watches the other patients grow hard, their thick cocks straining against their shorts, ready for their own electric massage.
