The low hum blends nicely with the droll sound of the manicurist's tools and is virtually undetectable. A sly smile bends my lips as I watch her shift...and squirm in her chair. She knows she's not allowed to orgasm without permission, and I plan to test that today. As I watch, I can tell she's fast approaching that threshold; her eyes shut tight as she fights to keep her body from betraying her. I quickly shut the vibrations off, and begin randomly flicking the power on and off so she doesn't. . well, you know." That I'd deny it? I will tell you we go to a lot of parties, so we don't have as much time by ourselves that I'd like."That seemed to sit well with her. To have sex we'd have to be alone, and we went to parties.

The most beautiful part was her face. Mary must have incredible trouble lying, in that her eyes and face tell everything..
