In the throes of self-pleasure, the uninhibited masturbator indulges in their desires, their massive cock throbbing in their grip. They trace the pulsing vein along their shaft, their other hand cupping their heavy balls, kneading gently. As their rhythm increases, their body tenses, their breath ragged, and with a final, desperate stroke, they cum, their cock pulsing as it unleashes a torrent of hot, creamy cum, coating their body in their own lewd masterpiece.
