"Cuckold, I've told you before, you're here to serve my pleasure, not your own," she reminds him, a hint of sadistic glee in her voice. He's her plaything, her pet, and she loves to tease him, to push him to his limits. Today, she's decided to indulge in a bi-fantasy, a threesome with another woman. He watches, helpless, as she kisses, touches, and fucks another. His cock strains against his pants, but he knows better than to touch himself without permission. After they've both cum, she turns to him, a wicked glint in her eye. "Clean us up, cuckold. Show me how much you love serving us."
