Kristi wished she had learned of the bizarre holiday tradition in the quaint little town before she had moved there. Within an hour of having arrived with a moving van filled with her belongings, she had been kidnapped and taken to a horse farm a few miles away. It was only when she saw the other harnessed and bridled women in the stable that she had to admit to herself that the promised teaching job didn’t exist—it was merely a ruse to lure her here as another victim for their twisted fetish. The town had no school; the town had no children.

She had fought with them as they had stripped her of all her clothing and fitted her with ponygirl tack, but as the days turned into weeks, she was faced with the inevitable conclusion that escape and resistance were pointless. Even now, she still could not believe that she and a dozen others were being treated and trained as show ponies.

They had explained it all to her the first day: “In order to generate revenue for our small town, we came up with the idea of holding an adults-only Christmas pageant. And what better way to do that than replace Santa’s reindeer with beautiful young ponygirls.”

And so here she was, wearing nothing but leather restraints and a sports bra all day, forced to obey the impossible demands of her leering trainers. Forced to relieve herself in front of, and be dressed and washed by, a coterie of strange men of all ages. Forced to live in a tiny bare stall and eat a bland unchanging diet from a feedbag.

All the other girls, with one exception, looked as if they had been there a while, and were used to their situation. Kristi did not want to know how long her horrifying imprisonment was going to last. She did not want to think of all the things she missed, or of what the future held in store for her.

Of course, her head and pubic hair had been shaved the first day, which was traumatic enough. She had had her long curly coppery locks since as long as she could remember, and losing them was like losing an arm or a leg. And being strapped down as some guy lathered and razored her crotch had nearly sent her into a panic. And if that wasn’t bad enough, there were the surgeries.

Even though she had seen the tiny posts jutting out from the bare heads of the other girls, it wasn’t until after she woke up in the hospital bed that she was told that small plates had been glued to her skull, which held the posts on which her antlers would be attached. They had also given her implants, increasing her from a B to a C cup.

The fact that they could so blithely make these extreme changes to her body terrified her. Even the implants bothered her, as she was a runner, and bigger breasts made it more difficult to run. It was only as the months progressed that she learned they were going to increase her to a double-D. A double-D! Only strippers and porn stars had such big breasts.

Training continued, day after day, the only changes over the months being larger breasts and sturdier sports bras. Pretty soon, the rituals of men standing by as she used the toilet, dressing her every morning, hand-washing her naked body every night, and shaving her head and pubic area become routine.

Kristi lost track of time. She had been kidnapped in February, and she was aware of time passing as the trees bloomed, the days got hotter, and then the trees lost their leaves, and the days got colder and shorter.

Then one day, things changed. After being dressed in open-cup bras, they were powdered down with talc, dressed in latex catsuits (deersuits? she wondered) that covered them from head to toe under their tack. The latex suits were light brown except for the breast and pelvic area, which were transparent. The worst part for Kristi was the ponytail butt plug, which still took some effort to get in, despite being lubed. Their arms were then bound behind their backs in leather sleeves, thrusting their breasts forward. Finally, fake antlers were snapped to their heads.

We have to train like this? thought the new ponygirl, whose sphincter muscles kept trying to force out the “blockage” in her ass. After warm-up exercises, they were taken through the snow to a barn. Inside, they were hitched to a sleigh. Kristi saw with dismay that she was the lead reindeer. Despite all she had been through, she still whimpered with fear as the reins were attached to her bit.

With a crack of the whip and a jerk of the reins, Kristi dug into the hard earth with her booted toes. Even with a team of thirteen young athletic women, it was still an effort to pull the heavy sleigh. In four inches of snow, it became even harder.

Kristi trudged through the thick accumulation, not wanting to believe how shitty her life had turned out. All because she had answered one little want ad. Her breath steamed out of her mouth and the nostril holes of the latex snout, turning to thick clouds of frost in the frigid air. She could hear the desperate huffing and puffing of the girls behind her as sweat pooled in various creases and ran down her body.

They were driven to exhaustion before being taken back to the barn. One of the girls had been sobbing for several minutes before they returned, but the trainers ignored her. Their pain meant nothing to their captors. The only thing that mattered was their performance.

They were given warm tea to drink and made to walk off the cramps and tiredness. Even though the stables were heated, the women shivered as their latex suits were peeled off their soaked bodies. Kristi thought that it would have helped if they could have hugged each other and taken solace in their shared torment, but they were kept isolated in their stalls at night, tethered and muzzled and blindfolded so they could not have any social contact with each other.

Shortly after this, they began giving Kristi injections in her breasts, which were now a massive double-D. They didn’t tell her what they were for, and all kinds of nightmare scenarios loomed in her mind. She didn’t feel any different, but after about a week, she began to notice that her pale breasts seemed even paler, if that was possible.

And then one day, as she was being dressed, it seemed as if her breasts were actually glowing beneath the cotton of her bra cups.

“It’s working,” said one of the men, pointing to her chest. He turned to Kristi and patted her on the cheek. “We’ve managed to isolate the DNA of bioluminescence from deep-water fish and fireflies, then alter it so that it accumulates in breast tissue. If things proceed as planned, you’ll make Rudolph look like a penlight with bad batteries.”

He laughed and went to take care of the others. The new ponygirl looked down at her massive hooters. Deep blue veins were clearly visible amid the soft glow of her skin. A tear spattered on one of her giant tits and quickly disappeared into the deep valley of her cleavage. They were turning her into a sideshow freak.

Their grueling workouts on the sleigh continued, and Kristi’s breasts got brighter and brighter. After a few weeks, she was able to light up her stall in pitch darkness. The glow was visible, even through the thick absorbent material of her bounce-proof bras.

And then December came. Tourists flocked to the area. Word of mouth was all that was needed for fetishists of all stripes to come for the Christmas show. As midnight approached, they lined the streets, bundled up in winter clothing and sipping hot drinks, the crowd electric with anticipation. Then, as the clock in the village square struck twelve, the sleigh came racing down the street, Santa cracking his whip.

Even from half a mile away, Kristi’s breasts could be seen bouncing along like the dim headlights of a car on a rough road. To support her massive chest, they had laced her tightly in a boned corsolette, with open cups to display her large radiant tits.

They went down one side of the street, then the other. Kristi was horrified to see that nearly everybody had a camera, camcorder, or picture phone.

They ended up in a small sports arena, where they were unhitched and tethered to the wall at one end of the arena. Kristi noticed a sumptuous buffet at the other end. The smell of food soon filled her nostrils, and her mouth began to water; before she knew it, she was drooling from her open mouth like an old bulldog.

Sports bottles filled with coffee were put in their feedbags, and the feedbags strapped to their bridles. As the ponygirls stood there sipping coffee, sweaty and uncomfortable under their latex catsuits, the tourists poured into the large room. They milled about, eating, talking, and admiring the ponygirls.

Kristi found herself the target of most of the attention, due to her massive glowing breasts. And there was nothing she could do about it, either.

After a couple hours, the ponygirls were made to do a half-hour of warm-up exercises before being hitched back up to the sleigh for the journey home. Even so, it was miserably cold, and the novice ponygirl was afraid she would get pneumonia before another day had passed.

Their show continued every night for the next three weeks. Though it was only a few hours every night, those few hours were an interminable hell of grueling exercise, freezing cold, and uncomfortable heat. Towards the end, she wished she would get pneumonia so that it would end her misery, but when any of them got sick, she was force-fed cold medications to keep her going.

Christmas came, and the shows ended. As a treat, they were each given a lousy candy bar. Kristi devoured hers in seconds, having not had anything even remotely sweet during the entire time of her captivity.

A few days later, two of the ponygirls were taken away, and Kristi never saw them again. Within several weeks, two new girls took their place. Kristi eventually figured out that older ponygirls who could no longer perform as well as they used to were sold at an auction. A girl who suffered a bad knee injury also disappeared. New girls were then kidnapped to keep the team strong and add variety. It soon became apparent that any ponygirl who had reached her late twenties was considered over the hill and expendable, and even young ones could be sold if the price was right . . .

The busty, genetically-modified ponygirl knew that she would fetch top dollar because of her unique chest, putting her out of range of most buyers, so that it might be a while before she was sold. But would her new life be any better than her old?
