I found myself helplessly constricted in a straight jacket which was attached to a ceiling mount, and then was lowered onto the sybian. Without the ability to move my hands, I was helplessly at the mercy of the operator. I was kept me upright with the rope looped through my collar and the stiff thigh-high boots. By cycling through intensity they were able to make me cum whenever they pleased, but would sometimes put me right on the edge, and then back off completely, leaving me begging for more. Eventually I had cum so many times my pussy couldn't handle it anymore and I pled for release, but they wouldn't let me go until THEY had decided I'd cum enough. They finally dialed it back and I nearly collapsed.
