The submissive's heart races as he hears his Mistress's voice, commanding and sultry, echoing through the room. "Show me what you've got," she demands, and he hesitates no longer, drawing out his throbbing cock. He grips it tightly, his hand moving in a blur as he races towards climax. His Mistress watches, her eyes gleaming with satisfaction, as he nears the edge. "Don't you dare come until I tell you to," she warns, her voice a whiplash, and he grunts, his body shuddering with the effort to comply.
