A mature man, alone in his space, allows his inhibitions to loosen, giving in to the primal urges that have been building within him. His hands, calloused from years of experience, unfasten his pants, freeing his throbbing, engorged member. He runs his hands over his body, tweaking his nipples, tracing the lines of his abs, before returning to his stiff cock. He pumps it slowly, his grip tight, his eyes closed, imagining the touch of another. His pace quickens, his groans echoing in the room, until he reaches the precipice, his body shuddering as he coats his fist with his hot, sticky seed.
