Bound nude in the Humiliation Position with their rumps in the
air and their heads shackled by their necks to the desks, their
shame seem great. However worst was to come. Their young bodies
were soon to experience what Oracle had dubbed, the education of
the ass. Unable to turn their heads all 4 screamed as the machine
began its activity. The machine inserted a vibrator into the rears
and withdrew while sending down sharp pokers onto their cheeks.
None of them had ever experienced such unpleasantness. They
screamed as again and again, the machine would drill into their
vulnerable posteriors and smack them with the pokers. Oracle
approached them in her wheelchair and waved at them as she wheeled
past. She then activated a lever. Whirling feathers from underneath
the ground began assaulting their feet and writing vaginas.

Not really all that interesting but damn funny story... I'll post
an interesting one if I find it...
