The milker's machine hums, its mechanical arms a blur as they work the captive cock with practiced precision. The man, bound and helpless, groans in ecstasy as the machine's relentless suction draws out his life-giving essence. His milk-sacks ache, but the milker's skilled touch soothes the discomfort, coaxing forth even more of the precious liquid. The room is bathed in the warm, golden glow of the setting sun, casting long shadows that dance and flicker with the machine's ceaseless motion. The milker, satisfied with the day's haul, releases the man, leaving him spent and panting, a contented smile on his face.
