Bored and alone, a man decides to entertain himself in the most primal way. He strips down, his thick, veiny cock already hardening at the thought of his own touch. He grips it tightly, feeling the pulse of his desire. His hand works up and down, spreading pre-cum along his length, the slickness allowing his hand to glide effortlessly. His breathing deepens, his body tensing as he brings himself closer to the edge. He imagines a lover's touch, a tight pussy gripping him, and with a final, hard stroke, he comes undone, his cum shooting out, painting his stomach.
