Caught in the throes of solo ecstasy, our unseen protagonist surrenders to the rhythm of the milking machine. His cock, twitching and engorged, is swallowed by the device, its powerful suction drawing out every last drop of his pent-up desire. The room fills with the sounds of his desperate moans, mingling with the wet, sucking noises of the machine at work. His body convulses, back arched, as he releases, his cum filling the machine's reservoir, ready to be emptied and savored.
