Tremble…

She squirms on the very tips of her toes. That is all she can do. Any other move drags the silk over her hypersensitive clit. Every breath stretches her nipples and tightens the thin nooses at the base. Drool drips from the coroners of her gag, little moans escape her lips. Her legs tremble at the strain and from the arousal. She has been more than ready to service him for some time, but for now she knows she is his erotic art to enjoy.
