In the dimly lit room, a solitary figure, Jack, finds solace in his solitude. His hand, calloused from years of labor, wraps around his throbbing cock. He strokes, slowly at first, feeling the velvety softness of his shaft. His breath hitches as he picks up speed, his grip tightening. The room fills with the sound of his hand meeting his flesh, a primal rhythm that drives him closer to the edge. His abs contract, his body tensing as he nears his climax. With a final, powerful stroke, he spills his seed, groaning in relief.
