The mistress commands, 'Stroke faster, my pet.' Her voice, a mix of sultriness and sternness, guides him through his masturbation. She counts down, 'Ten... nine... eight...' With each number, his hand moves faster, his breath comes in shorter gasps. She orders, 'Don't you dare cum until I say so.' The room fills with the sound of his hand slapping against his cock, his moans of anticipation, and her low, commanding voice, 'Seven... six... five...' The air is thick with the scent of his pre-cum, his muscles tense, and he fights to obey her orders, waiting for the final countdown.
