On a crowded train, a chubby man, discreetly unzips his pants, his meaty hand disappearing beneath his waistband. He strokes his cock, eyes darting around nervously, yet excitedly. Passengers oblivious, he builds a steady rhythm, his face flushing, his breath quickening. Suddenly, he lets out a low grunt, his hand pumping faster, before pulling out his cock and unleashing a thick, creamy load onto the floor, a Bukkake-style mess for the unsuspecting commuters.
