A ritual as old as time, a man, alone and unobserved, indulges in the primal urge to pleasure himself. His hands, rough and calloused, glide along his length, the friction building a fire within. The room fills with the sound of his ragged breaths, the slick wetness of his arousal, and the quiet moans of his approaching climax. With a final, shuddering release, he paints his chest with his essence, a testament to his solitary passion.
