Under the guise of a medical examination, the doctor's true intentions are revealed as he unzips the twinks' pants, their hard cocks springing free. He teases their balls and shafts with the electro-stim wand, making them buck and moan. The doctor's rough, calloused hands join the dance, twisting and pumping their cocks in time with the electric pulses. The twinks, lost in ecstasy, beg for more, their cocks throbbing and purple with need. The doctor obliges, pushing them into a final, intense orgasm that leaves them panting and spent, their cum painting the clinic floor.
