The Bull Master, a man of considerable size and confidence, takes center stage in his private sanctum, dedicated to the art of self-pleasure and body modification. His massive cock, already a formidable sight, is joined by his balls, which he meticulously prepares for enhancement. He applies lube to his heavy sac, the cool liquid sending shivers through his body. With practiced ease, he places the vacuum pump over his balls, turning it on with a flick of his wrist. The machine hums to life, pulling at his flesh, drawing his balls out and up, inflating them to a size that defies belief. His cock twitches in response, eager for the main event.
