Mistress Kym, clad in leather, secures her cuckold, Marc, to a post with a sturdy chain. He's collared and leashed, his eyes downcast. She teases him, running a riding crop along his body, leaving red welts. Kym orders him to stay, his cock hard and aching, as she leaves for a night out with her friends. Marc's humiliation grows, knowing he'll be punished for his arousal upon her return.
