Chapter 6 While all this was happening to me, Master was expanding his empire. He must have been training them elsewhere because suddenly the stables were filled with little rubber-clad stable boys, looking very much like the rubber nurses at the clinic. All were in their mid-twenties, covered in rubber and wearing seven-inch stilettos and all had their genitals locked in impossibly small chastity tubes and of course they were smooth gummed. There were only two differences compared to the rubber nurses at the clinic. Master's stable boys wore red instead of white rubber and they had been allowed to keep their hair and in fact their hair tended to be long and cut in girlish hairstyles. They were perfectly docile and obedient, so it was fair to assume that Master had trained them very hard before letting them out in the stables.

They now took over the task of feeding me cleaning me and keeping me sealed in rubber, impaled by the brutal dildos. I never saw one cum and their poor imprisoned cocks always dribbled pre-cum. When I was plugged into the automatic sucking machine they always looked at me with extreme envy. I have no idea where they slept since I was always sealed inside my rubber cocoon when that happened, but I can't imagine it was someplace nice and comfortable.

When the stable boys arrived, so did the first new pony, a huge black pony, armless like me. The sign on the bars surrounding his enclosure read "Tony. Racing pony" and I got the feeling that he certainly wasn't as easily controlled as I was. At least not at first. I think he put up a real fight the first few days before Master broke him, but to tell the truth I don't really know. My world had narrowed down to the overriding need to please Master so that I could get release. All my energy was consumed by this and I didn't really notice others, only Master had my undivided attention. Not that I didn't obey everything the stable boys told me to without hesitation, it was just that they were nothing more than a poor substitute for Master.

As the stables was gradually filled up with ponies in various stages of training, Master let the stable boys ride me to keep me in shape while he was occupied with training others. There was no difference in the level of perfection required of me. The stable boys had also been trained to perfection and they knew that failure on their part to keep me in shape would result in terrible punishment.

Master also had house slaves and usually these accompanied him to the stables to watch him train us ponies. The function of the house slaves was apparently to watch Master admiringly as he trained the ponies and to give him a blowjob or let him fuck their assess whenever he needed it. All the house slaves were very pretty boys in their early twenties with very delicate and most cases feminine movements. Of course what little clothes they wore was always fine and very sexy and all wore stilettos, the minimum height seemingly seven-inches and often much higher with the help of platforms. All had their members imprisoned in chastity tubes in a manner that was visible to the rest of the world and not one of them had any teeth in their mouths. At least two of the house slaves were shemales with long hair, completely feminine features all the way down the rounded hips, ample butts, big tits and fine skin complexions. The shemales were always perfectly made up and if it wasn't for the fact that Master demanded that their chastised member were always visible no one would have thought they were, or at least had been, men.

With the introduction of the house slaves Master stopped fucking the ponies altogether. As he now always had pretty slave boys just waiting to please him at his hand, his physical contact with the ponies was reduced to sitting on our back as we ran and punishing us when we failed to live up to his demands.

This did not diminish the love and devotion I felt towards Master. Rather I now strained even harder to please him in the futile hope that he would once again fuck me and I am certain the other ponies did the same thing.

Master also began racing me and the others. Some, like Tony, competed in flat out races about who came first, whereas others, like myself, competed in style.

The races were enormous events were many hundred Masters competed, many with more than one pony. There were all kinds of ponies at these races, ranging from "slaves" in almost vanilla relationships, to ponies that were just as brutally modified and controlled as Master's ponies. The ones from vanilla relationships had usually been tricked by their lover and had without knowing it entered in a contest that marked the beginning of permanent slavery for them.

At the races it was bad for the concentration of a pony to be too much in need of release, so many owners brought slaves just for the purpose of proving relief for their animals. Some brought little rubberized slave boys who sucked and fucked like there was no tomorrow, but a few brought special ponies for this purpose. Theses ponies were all geldings with tiny useless appendages hanging from their smooth crotches. Even as I slipped my cock into the ass of a gelding Master had borrowed, I shuddered with fright at the thought of that ever happening to me.

Mostly I did well at the races, finishing in the top five, but as always nothing but perfection was good enough for Master and that meant winning. There were more than a few ponies that had been trained as thoroughly and brutally as I had been and subjected to modifications as drastic as the ones I had been through so many times the competitions ended with me being punished. First Master would punish me at the racetrack, most often by applying electricity to my genitals and whipping my body, but the punishment would not stop as we left the racetrack. Back home in the stables I would be denied orgasms for up to a week, depending how badly I had lost. A week of enforced abstinence made my balls grow to the size of grapefruits and every single moment of my life filled up with the need to cum and the terrible pain in my balls.

As time went on I improved my winning percentage, but this only increased the pressure on me. For every time I was milked, my production of semen went up. Soon once every hour during the day and once a night was not enough. Soon I had to be milked twice every hour during the day and at least three times each night. My world shrank further as the haze of constant need for release and constant orgasms occupied more and more of my already very thoroughly conditioned mind.

Master also began experiment with new ways to make life harder and more demanding for the ponies. First he introduced racing without the use of my sight or hearing. I was fitted with a hood that cut off all sight and dampened sound down to nothing. I now had to rely completely on the commands I received through the reins. It wasn't really that much of a change for me. My mind was already so preoccupied with my desire to please Master that I rarely saw where I was going but instead relied on my rider. Having my sight removed when running was just taking it the final little step.

Breath play, however, was another matter. Master would drastically reduce my ability to breathe properly, thereby sending me into panic attacks as I thought I was going to die. Of course that wasn't the whole story for me as I soon found out that the intense fear of suffocation coupled with the pressure on my throat turned me on something awful. Of all the added discomforts Master had poured on me since I had first come to accept that I was indeed a pony, his pony, this was the one that turned me on the most. And the more excited I became, the more sperm I produced.

Master used two ways of restricting my breathing. The first one was by tying a string around my throat just tight enough to allow me to breathe with great difficulty. I would run with just enough air for me not to collapse, constantly in fear of choking and always thinking how much I wanted to please Master. The second method was to pull a clear plastic bag down over my head and tying it off around my neck with duct tape. In the bag there was a tiny hole, just big enough for me to survive on the air coming in, but definitely not big enough for me to breathe comfortably. As my breathing became increasingly labored and the bag fogged over I was once again plunged into extreme fantasies of brutal and punishing sex with Master and sometimes the fantasies would end with me being strangled to death while Master's cock pounded into me.

After breath play had been part of my daily existence as a pony for some time, I noticed that I was becoming dumber. There was no change in the way I behaved, since that was dictated by Master's orders, but one day I noticed that I was unable to read the sign on my enclosure in the barn. I couldn't read the sign on the next enclosure either and I was filled with a sense of panic. I couldn't quite understand why I was panicking, but I knew that something bad was happening. The feeling passed as I was impaled and my ass was once again filled in that familiar brutal way and I was sealed in rubber.

I thought no more about it, but just accepted it. I was after all just a dumb, worthless pony slave.

I did, however, have a real panic attack when I realized that I was unable to understand most of what the stable boys said. The didn't talk much, since Master of course didn't tolerate anything even resembling idle chatter, but they did utter a few sentences during an evening. So it was a while before I noticed, but slowly it dawned on me that most of what they said were just sounds without meaning to me. Deep down I knew that I should be able to understand what they said and the realization made me panic and refuse to obey their commands as they tried to get me impaled for the night. After much whipping and liberal use of the cattle prod they were finally able to subdue me and impale me on my pole, locking my legs in place. I was still in a state of panic and they decided to call Master.

It was quite clear that being called to the stables at night did not sit well with Master and the rubberized stable boys delivered their explanation with their heads pressed to the ground. Trailing behind Master was one of his shemale slaves, dressed in nothing more than stilettos, a very restrictive corset, a collar and an armbinder. Cum was running down the inside of her leg and her cock looked blue as it strained against its prison.

Master heard their explanation and moved over to me. I stood on my pole, whinnying senselessly in panic. Master shouted something at me and slapped my face brutally, but I couldn't understand what he was saying. This went on for some time until Master found out what was going on. With a curious look on his face he approached me and spoke to me in quiet, soothing tones and slowly I calmed down. I still understood only a tiny fraction of what he said, but his presence and his soothing voice did the trick. Even after I had calmed down he continued talking to me, presumably trying to find out just how much damage I had sustained. The longer he talked, the more he smiled and it was clear that my state as literally a dumb animal delighted him. In the end he ordered his shemale house slave over to kneel in front of him and provide him with a blowjob as he enjoyed the situation. He came laughing at my lack of comprehension and as he left I was once again sealed in my rubber cocoon.

The next few days my performance was poor because of the shock, but after a day of painful abstinence I was once again focused on my life as a pony and I accepted that I was just another dumb animal. At any rate my mind could handle only simple thoughts and only for short periods of time, so the thought that I should be able to understand what everyone said was soon forgotten.

I have no idea how long I lived as a pony. I think it was for quite a few years, but in truth I don't know. I just ran with complete and utter devotion to Master, enjoying every glorious orgasm he saw fit to grant me.

In the end I had to be milked three times every hour, both night and day. The milking device on the fence was replaced by a mobile one strapped to my abdomen, constantly holding my cock and pumping my semen to a large bottle placed just below my saddle. My life was a constant state of obedience and extreme sexual pleasure. My mind had dwindled further from the near constant breath play and I now understood very little of went on around me.

Then one day my routine was broken as I was led out of the stables in the morning. I had no saddle on my back and no plug with a tail in my ass and instead of being led out for a training run, I was led up to Master's house. I had never been inside the house and I hardly recognized the house for what it was. Still high stepping my very best I was led into a large room where Master sat on a couch surrounded by devoted little house slaves. In front of the couch was a pole just like the one in my enclosure and soon I was impaled on it just like I was in the stables. My ankles were tied to the pole and a low table was placed in front of me so that the edge of the table touched my shins. On the table one of the house slaves placed a very large bucket.

Then at Master's command two of the little chastised house slaves fitted me with a chastity tube, just like the one they wore themselves. Since my cock had long since reached a state of permanent erection, this took quite some doing, but using a combination of a very large icepack and some vicious electric shocks to my balls they finally managed to shrink it down to the very small size needed to fit me with the tube. Both looked very proud as they say down at Master's feet.

I of course didn't understand what was going on, only that it hurt awfully. My cock desperately strained against it's prison, but of course the steel tube made sure it couldn't get hard. It had also been sometime since my last orgasm and I had begun to feel the ache. The ache just got worse and worse, but it was quite clear that no one would do anything about it. Master and his slaves continued lounging about. Occasionally he fucked one of them or tortured them in some way, but no one paid me any heed.

By nightfall I was desperate and my sounds became annoying to Master so he had me gagged. The little house slaves on the other hand were all smiling, even if most of their smiles were strained as Master had proven that he had an insatiable appetite for causing pain. All his slaves had been screaming at some point during the day, but they all did their best to look as if they enjoyed it a great deal. Even my slow and damaged mind understood that they were all terrified of him, just as I was, and that they were probably all hopelessly in love with him, just as I was. Like me, they were trapped. Like all his slaves they had been conditioned to love him, no matter how their feelings had been before he caught them.

When night fell Master went to bed with most of his entourage, but he left one slave to watch me. It was one of the shemales and she spent all night kissing and caressing my body at his command.

In the morning the pain from my crotch was unbearable. I thought it might have been years since I had last gone twenty-four hours without an orgasm and my balls felt like they were the size of watermelons. As Master and his house slaves took their place in the couch, this was confirmed when Master had a mirror placed off to one side so I could see my own balls. They were indeed the size of watermelons and it looked like the skin was about to burst.

All through the day I watched in fascinated horror as my balls grew to a grotesque size. When the sun went down the pain was unbelievable and I would do anything to get rid of it. Master and his slaves had gradually stopped talking and were instead watching my balls intently. In the mirror I watched as they grew until suddenly a very small tear appeared in both of the ball-sacks almost at the same time. By that time the pain couldn't get any worse so I didn't really feel it. The tears grew very slowly at first, but finally it was like the skin just gave way and suddenly my scrotum burst open, like two large zippers had just been pulled, and my balls exploded out through the opening. They were huge, the size of large grapefruits, but as they burst out the most impressive thing was the enormous amounts of cum that exploded out with them. It was like a flood of blood-laced cum that exploded out of my scrotum along with my testicles. I screamed for all I was worth and passed out as I saw my balls land in the bucket along with most of the semen, tearing away the last few string attaching them to my body as they fell.
