Jack's solo session begins as he sets up his auto stroker, the machine whirring to life. He strokes his cock, getting it nice and hard before sliding it into the mechanical wonder. The stroker's rhythmic motions feel amazing, and Jack's breath hitches as he loses himself in the sensation. He experiments with different settings, his body glistening with sweat as he chases his orgasm. When it finally hits, Jack's body convulses, and he cries out, his cum filling the stroker's collection chamber.
