Behind bars, a burly prisoner finds solace in his own hands, stroking his rigid cock with fervent urgency. His cell becomes a private theater, the dim light casting shadows as he pleasures himself. The air grows thick with his musk, the sound of his hand slapping against his flesh echoing in the confined space. His body tenses, and with a final, desperate tug, he unleashes a torrent of cum, his load painting the cold, hard floor.
