Having the sensation suddenly stop from her clit was agonizing to her.  Her body trembled softly, and her legs tried to push up without voluntary control to try to force herself back onto the wand.  However, she was too firmly tied to the table to be able to move.  As good as the slow and methodical sensations felt, her body was too hyped up and desperate for some fast, simple but forceful euphoria to send her over the plateau.  She barely knew what she was doing, but the yearning in her body was too strong to ignore.<br/><br/>She managed to stop herself from begging further, but she couldn't stop herself from shifting, trying to get herself closer to that sensation of rapture that the wand kept promising her if only the doctor would hold it still for long enough on the right spot.  She was trying so hard to be good but she just couldn't help it, and it made her feel so guilty that she just couldn't relax and accept the treatment.  Slowly her eyes began to moisten, her thighs trembling but never long enough to feel what she could only imagine would be truly beautiful.
