In the dimly lit room, Peetee's eager hands grasp the vacuum pump, a sinister grin spreading across his face. His massive cock throbs in anticipation, but today's focus is elsewhere. He meticulously places the pump over his swollen balls, the rubber seal tight against his skin. A switch flick, and the machine roars to life, pulling at his sensitive flesh. His breath hitches as the vacuum intensifies, his nutsacks aching and swelling within the glass chamber. He groans, pleasure and pain intertwining, as he endures the testicle torture, his cock twitching with each pulse of the pump.
