Bathed in the cosy glow of the kotatsu, a man loses himself in the rhythm of his own touch. His hand, slick with pre-cum, glides effortlessly along his throbbing shaft. The heat of the kotatsu and the friction of his hand build a pressure inside him, a pressure that demands release. He feels it building, a second time, his body tensing, his breath hitching, and with a final, powerful stroke, he comes undone, his cock pulsing, his body shaking as he paints the kotatsu table with his essence, the mark of his solitary, intense pleasure.
