A lone teen boy, in the throes of puberty, discovers the joy of self-pleasure. With a mischievous grin, he whips out his hardening cock, stroking it eagerly. He's no stranger to the feeling of his own hand around his shaft, but today, he wants more. He wants to see his cum, to feel it on his skin. He jerks off feverishly, his breath hitching as he feels his orgasm approaching. With a final, desperate stroke, he unleashes a torrent of cum, coating his chest and stomach. He's left panting, a satisfied smile on his face, his body sticky with his own semen.
