A Japanese office worker, craving release from his monotonous day, begins to pleasure himself discreetly at his desk. He starts by pinching and twisting his sensitive nipples, moaning softly as the sensation sends jolts of pleasure down to his crotch. His cock hardens in his pants, and he can't resist the urge to stroke it through the fabric. Slowly, he unzips his pants, letting his thick, uncut cock spring free. He strokes himself, his pre-cum lubricating his hand as he picks up speed.
