The tied girl was in delirium. She had just been administered with a new type of drug. The effect of the drug was simple. It was stripping the woman temporally from her conscious mind turning her into the perfect slave for a little while. There was only one side effect, that turned out to be quiet useful. The deepest sexual animalistic desires of the subject were resurfacing and multiplied. Practice has shown that part of the training remains even after the effects of the drug have passed.

The initial delirium the 22 year old Anya was in was now fading. That's why she willingly obeyed when she was ordered to stand up and undress. The spectators began to whisper to one another. Quiet a few people had come this evening to the event. In less then a minute the new young slave was naked on the stage. Next, she was invited to put on the extremely high heels she was given. They were really tall so it was actually almost impossible to walk in them. Anya obediently put them on, but what she didn't know was that their base was covered in a special glue agent. Now they were completely glued to her skin and she could remove them only with the help of another chemical.

The enslavement show was different every time. Now while Anya was barely standing a horizontal round wooden beam was lowered from the ceiling. Two men from the staff grabbed her hands, spread them horizontally and tied her tightly on the beam. Next they bent down, spread Anya's legs and fixed the heels to the floor with pre-prepared clamps.

Now the real show was about to begin. The beam was moved slightly backwards. Her body was dragged backwards by the beam but because of her fixed legs it only inclined about at about 45 degrees. The staff men brought a metal rod to the stage. It had something like a rubber saddle on top of it. It turned out that it was a support for Anya's pelvis. The men positioned the saddle of the rod just against her ass and lift it. Now all of her limbs were strained and her shaved cunt was clearly visible, pointing perfectly towards the crowd.

Now the real stage of the enslavement process started. Another man from the staff came to the stage. He was bringing a bag of instruments. He squatted just below her cunt and started working. He had done this many times, so he knew how to move to leave the procedure visible for the crowd. With one of his sharp devices he began puncturing her cunt lips making round holes in them. Maybe because of the drug effects Anya's brain was interpreting the pain as pleasure. She moaned in pleasure. Her cunt was now wet but the men proceeded undisturbed. When he was ready, there were more then a dozen holes in her skin. Not wasting time, he took out inox steel rings from his bag and inserted them in the holes he punctured. When the last ring was in place, her cunt was completely sealed.

The crowd watched with interest as the man went near Anya's chest. Two metal objects were drawn out of his bag. They looked like big nipple piercing, but actually they were something more. They were round, there form was similar to a small umbrella but instead of a handle they had a few needles around their perimeter. The first one was pressed against her left nipple. The sharp needles dug in the flesh of her tit. The metal completely covered her nipple, the needles going deeper and deeper. The biggest spike in the middle pricked the center of her nipple. With the last push the needles had changed their angle. Her right tit underwent the same procedure. Now both her nipples were jabbed under their metal covers. Her tits had started bleeding but somehow she was still feeling pleasure instead of pain.

An one hour break was announced by the speaker. He also encouraged the people to get on stage to take a closer look on the tied slave. A few men took the opportunity to jerk their dicks on her sealed cunt covering it with good amount of cum. With the closer look they actually saw that there was a label on her new metal nipples that said "anal slave".

When the break was over the people that were still on the stage were asked to leave. When everything was set for action again, the beam was moved forward and the support was removed from underneath Anya's ass. Again her body was straight. The dried traces of blood from her tits were now clearly visible for everyone.

Big machine was positioned between Anya's legs. The giant dildo was slightly lubed. Nobody wanted to rip the slave's virgin asshole. The machine was turned on. It moved so slow, only gradually increasing the pressure on her sphincter. The programming was done in a way to give her possibility to adapt. Multiple times the lubed head of the plastic monster pressed against the entrance of her asshole until finally it opened. Having less resistance on its way the machine started to increase the up and down traveling distance of the dildo. Slowly but surely it was going in deeper and deeper every time retracting almost completely, not leaving possibility for her sphincter to clench and close her new fuck hole.

The moving anal impaler was now traveling through her bowels with a regular rhythm. Anya was crying and moaning from pleasure. Slight adjustment was done on the machine controls. Now the dildo went even deeper in her rectum disappearing completely inside her colon with every thrust of the machine. The observers couldn't see, but now the wider ring of the plastic base of the dildo was ramming and destroying her sphincter on every push and on every withdrawal. Her asshole was steadily being converted from mainly a shit pipe to a regular fuck hole.

Soon the millions of nerves in her ass overloaded Anya's drugged brain. Intense waves of pleasure surged through her body. The convulsions of her orgasm broke her completely as the dildo continued it's march through her rectum. She was experiencing her first anal orgasm in her life and her first orgasm as a future slave. Once all the effects of her pleasure had faded, the machine speed was greatly reduced. The auction for her was now about to begin. The effects of the drug were about to wear off also. Anya was soon about to find out that the machine will continue to fuck her ruined asshole slowly till the end of the auction.
