The submissive kneels, eyes cast down, awaiting his Mistress's touch. She circles him, her heels clicking on the cold stone floor, her breath heavy with anticipation. She traces the curve of his ass, then firmly grips his cock, making him jolt. "Stay still," she warns, before spitting on his cock and rubbing it in with her palm. She presses her ass against him, feeling his hardness through her thin dress. She grinds, moaning softly, her pussy dripping onto his cock. "You will not cum," she orders, before walking away, leaving him aching and desperate.
