In the dimly lit compartment, a lonely man finds solace in his own hands. The rhythmic clacking of the train on the tracks sets the pace as he begins to stroke his growing erection. His calloused hands, rough from years of labor, provide a unique sensation as they grip his throbbing shaft. The window reflects his intense gaze as he pleasures himself, the cool glass offering a stark contrast to the heat building within him. His breath hitches as he nears the edge, the tension in his body mirroring the anticipation of the approaching station.
