Glass table
From Voyeurweb's Wiki about Sex
Glass table: A device consisting of a horizontal surface made of glass and the supporting frame and legs arranged in a mostly circular or rectangular shape. The only known usage of this device is to have pantyless females sitting on the glass surface for the purpose of taking photos from under the glass. During the golden age of automation, this very simple device was further developed by integrating a camera and a printer into the glass table. The modern form of these glass tables are now called "copiers". These newer devices allow you to instantly print pictures of her bare ass and pussy pressed against the glass. Caution: Make sure you do not break the glass when sitting on it. You might hurt your ass and pussy badly.
