Paige felt the wind blowing through her long, dark hair as she rounded the corner, the white horse beneath her contrasting with her dark skin. Paige was focused, blocking out the sounds of the other riders and of the crowd. She was only focused on the finish line; though she knew that winning was important to all of the jockeys riding in the Kentucky Derby, the stakes were much higher for her than for any of them. “Freedom,” she thought to herself. “Freedom.” A small smile came to her face. The other riders were far behind her and she began thinking of all of the things she would do with her freedom. High on her list was getting far away from the ranch. Paige intended to head for somewhere she could be seen as equal. Even if Sara freed her, Paige knew that her half sister would always see her as a slave.

Paige began thinking about the first time she ever rode Wildfire. She had been cleaning the horses’ stalls. It had been a gorgeous summer day and Paige couldn’t bear even one more duty. She had to be outside. Since Sara was nowhere in sight, Paige had taken Sara’s beautiful white horse outside for a ride. To Paige, being on horseback felt like freedom. She rode around the ranch, oblivious to the fact that Sara had returned home unexpectedly and discovered her. Sara had been angry that day, the first time she ever saw Paige ride the horse. But part of Sara realized that Paige was a natural born horsewoman. She and Wildfire moved so naturally together.

The anger Sara had felt that day was no match for what she felt when she saw the other rider pull in front of Paige, winning the Kentucky Derby. Sara screamed, cursing her sister when she saw that Paige had lost. There was no reason that Paige should have lost and Sara was beyond angry. She was surrounded by friends and was humiliated by the loss of the race. Sara had told all of her friends about what a brilliant rider Paige was, how talented she was on horseback and Paige embarrassed Sara by losing. Sara felt like a fool and the more she thought about it, the angrier she became. Sara fixated on revenge. She was going to make Paige pay for her laziness and for humiliating Sara.

Paige began brushing Wildfire. She took her time, brushing long, slow strokes down the horse’s back. Paige was not eager to leave the stall and she planned to spend as much time as possible in the stall with the horse. “What happened?” Paige heard a curt voice behind her answer and Paige felt her stomach fall.

Paige dropping the horse’s brush and ran to Sara, dropping to her knees before her. “I am so sorry,” she apologized. “I was daydreaming and I am so sorry. I lost my focus. It will never, never happen again.” Paige’s stomach turned as she looked up into Sara’s disappointed and angry face. “I can make it up to you,” Paige promised. “I am going to win races for you. Any race you want. All of the races.”

Sara smiled into Paige’s upturned face. “Stand up,” she said. “Of course I forgive you, sister.”

Paige stood in front of Sara. She was so happy to hear Sara call her “sister.” Though Paige and Sara shared a father, Paige knew that Sara did not really consider her a sister. She was a slave, just as her mother had been a slave. Paige’s mother, Victoria, had fallen in love with her owner, Richard Scott, Sara’s father. Paige had heard from other slaves at the St. James Ranch that Richard had loved Victoria, too, but that he did not dare cross his wife. Sara’s mother, Caroline, had been a very cruel, vindictive woman who personally made certain that Victoria was hung to death for having an affair with Richard. Paige wanted to cry every time she thought of her mother, hung just for loving a man she couldn’t be with. Paige has been a tiny baby when her mother died.

Paige had been raised on the ranch, but Richard never treated her like a daughter. She was merely a slave to him and Sara always treated her the same way. Paige had always longed to be a part of a family; instead she didn’t fit in anywhere. She was a slave.

Paige felt tears well up in her eyes when Sara wrapped her arms around her. She held on to Sara a moment longer than necessary. When the embrace ended, Sara took out her perfume bottle. Instead of spraying herself, however, Sara sprayed the bottle in the face of her half sister. A few moments later, Paige’s eyes rolled back into her head and she fell onto the ground.

The first sensation Paige was aware of when she awoke was the feeling of confinement. Paige’s head felt fuzzy and she blinked, trying to clear her head and trying to figure out why she couldn’t stretch out her body. Paige looked around and she became aware that she was suspended and from her surroundings, she determined that she was in the metal shed out behind the stable.

But the metal shed was never used, she thought. The only reason anyone was ever sent there was . . . punishment. Paige began to panic as her head cleared and she realized that she couldn’t see the rubber bag that hung from a beam in the ceiling of the shed. Immediately she realized the reason why: she was in the rubber bag!

Paige had never had any experience with the bag or with the shed but she had heard horror stories. It was a horrific punishment and Paige realized that she was trapped. She opened her mouth to scream but could not. She was gagged with a penis gag that was connected to a small hose. Paige recalled that the tube was a feed tube and as she made the realization, she knew that the tube was in her mouth and down her throat. Paige struggled, trying to free her hands but she was not able to move at all. She was stuck, tethered to the bag.

Paige was panicked, as she thought of how the bag was described to her by a fellow slave who had had the misfortune of helping to set up the bag in the shed. As far as Paige knew, no one had ever actually been in the bag before. It was a punishment greatly feared by the slaves at the ranch. It was a large black bag with straps on the inside and outside. When Paige looked down, she could see strap after strap on the outside of the bag and she knew that there were straps inside as well. She wasn’t sure how many, but she felt them all over her body. Paige was completely immobile, held in place by each of those straps. She wasn’t entirely sure what the punishment was, but being held inside so helplessly, unable to move, was certainly punishment enough.

Paige was still struggling against the tight straps when she heard the door open. Paige was facing the door and she saw Sara walk into the shed. Sara tossed her hair and smiled at her half sister. “My, don’t you look comfy, darling?” she said as she walked closer to Paige. “I hope you don’t mind, but I took the liberty of putting you in that thing so you can spend all day and night daydreaming. Just like you did during the race.” Sara was now standing in front of Paige, smiling wider. Paige felt her body turn cold even within the thick rubber bag as she saw the look on Sara’s face. Sara got close to Paige, as close as she could, as Paige was raised up off of the ground.

“Now, Sis,” Sara said, hissing the last word and making it sound like a complete insult. “You humiliated me and I’m going to make you pay. Pay and pay and pay until you wish you had never been born. I intend to make your life a living hell. You lost the race and I am going to make sure that you suffer for that.” Sara smiled again, widely. “I just want to tell you a little bit about the punishment bag so you’ll know what you’re in for. You already know about the straps, all those delightful straps inside and out that are keeping you in place. And of course you know about the penis gag filling your worthless little slave mouth. See, that makes sure that you can’t speak, but there is also a feeding tube to make sure you get your nutrients, darlin’.” Sara used the winch on the wall to slowly lower the punishment bag until Paige was eye level with Sara. Sara moved closer so that she was standing with her face next to Paige’s gagged face so she could look into Paige’s eyes.

Even beneath the gag, Sara could see the confused expression on her half-sister’s face, so she decided to explain further, knowing that what she was able to say was going to horrify Paige. “Your feeding tube is connected to the machine behind you,” Sara said. “There are tubes in the bottom of the bag that will connect all of your disgusting little wastes. Your sweat, your feces, your urine. My lovely machine there purifies your waste, adds water and certain enzymes that will help enhance those breasts of yours and then it feeds the liquid back to you through your feeding tube. It is genius, really, and it means that you can be kept here for a long, long time.”

Paige’s eyes grew wider as Sara continued to talk. She was horrified. Surely Sara wasn’t serious. She couldn’t just leave her there. The thought of being fed like that, of being trapped like that, it was making Paige begin to panic. She fought again against the straps, but she couldn’t move. The bag was so tight around her and the straps felt like they were made of metal. She felt metal against her skin.

“Oh, Sis, I didn’t even tell you about the best part,” Sara said, the same cruel smile set on her face. “Oh, but if I tell you, it would spoil the surprise. I don’t want to do that to you.” Sara leaned in and kissed Paige’s penis gagged face. “Bye slave. Enjoy.” Sara moved the bag back up so that it was suspended in the air and then walked over to the machine behind Paige and she flipped a switch. She waved goodbye and then closed and locked the metal shed door.

Left alone in the otherwise silent shed, Paige heard the machine behind her begin to hum and then the bag around her began to heat up. It was growing hotter and hotter so that it was uncomfortable around her body and she tried to squirm away from the coils of heat, only to discover there was nowhere to go. She felt herself began to sweat and she tried to scream in frustration but the penis gag blocked the noise so that it was only a small groan of protest that escaped her lips.

Then, the real punishment began. Paige felt a painful shock administered to her left nipple. She tried to writhe away from it but it subsided quickly and she felt a shock on her right thigh. Then her labia. Anus. Stomach. Nipple again. Random shocks happened throughout her body and she fought against the bag, trying to free herself, trying to stop the shocks, but there was nowhere to go. She was utterly helpless. After some time, Paige became aware of an urgent need to pee. Though there was no one around to see, she felt her face flame with the shame of having to pee into the bag. She began to struggle again, and she held the pee until she felt pain in her bladder and she had to release it. She felt the hot urine run down her leg and collect at the bottom of the bag.

Paige heard more noises from the machine behind her, a small sucking noise as the urine was pumped from the bag and into the machine. Paige remembered what Sara had said and she tried again to free herself. She was frantic as she heard the machine behind her hum and then the sound of water running. No, no, no, no, no, no. The words kept going through Paige’s head. This was a nightmare. The heat. The shocks that stopped and started and stopped and started with no real pattern so she could not anticipate them. And now this. The shed was so silent that Paige could hear the tube begin to fill and then suddenly the liquid mixture was in her throat. She couldn’t taste it since the tube bypassed her mouth and deposited the liquid into her throat. She wanted to gag, to cough, anything to keep the liquid from going into her body, but there was nothing she could do. The liquid went into her body. Paige then realized how hopeless this was. She hadn’t wanted to believe Sara, but it did appear that she was going to be trapped here in this bag for some time. She felt tears stream down her face at being trapped so completely. Paige realized too just how deeply Sara wanted her to suffer. She had always known Sara didn’t care for her, but for the first time, she truly understood that Sara wanted her to suffer, to take pain and to be in agony.

Paige was exhausted. She had no idea how long she had been in the bag, but it had to be days at the very least. It could have been weeks. It felt like months. She had no way to mark time, had no idea how to determine whether it was day or night. She hadn’t been able to sleep for any length of time, though when the shocks ceased for a short time, she would close her eyes and drift off. Always she was awoken by a shock, usually to her vagina. Those shocks still made her scream into the gag.

Paige was stunned by a sound and she had to close her eyes and turn her head when light came in through the shed door as it was being opened. Sara stepped into the shed but she didn’t even glance toward Paige. Instead, she walked around the shed talking to her girlfriend, Rachel, on her cell phone. Sara had wanted to make sure Paige was suffering and she knew immediately from the look she saw on Paige’s face when she walked through the door that the punishment bag was doing its job. But Sara wanted more, wanted to make sure Paige continued to suffer, as Sara knew she would have to take Paige out of the bag soon. She asked Rachel for her suggestions.

“You know, I just read something online that might interest you,” Rachel replied. “There is this pony girl competition in Texas. Huge prize for the owner of a winning pony girl.”

“Pony girl?” Sara asked.

“Oh, yes, definitely!” Rachel replied. “I know you want to keep punishing the bitch and pony girl training is very painful. You know your little slave knows a lot about horses so she should have no problem learning how to be one.”

“Oh, I do like the thought of making her suffer more. Do me a favor would you? Find out what you can about this competition and then get back with me.” Paige watched as Sara walked around with her phone and then heard Sara laugh and say “Oh, you are so bad! I hope you’re that bad when I see you later.” Sara hung up the phone and looked at Paige. “Just wanted to make sure you’re still alive. Well, see you later.”

Sara started walking toward the door and as she left, the small glimmer of hope that Paige had felt was gone, too. When Paige saw Sara, she thought that was the end of the punishment bag. The horrific, mind-numbing awfulness of the punishment bag. The endless shocks. The disgusting liquid forced into her body through the feeding tube. It was all too much to endure and Paige thought that finally she would be free, but Sara just closed the door behind her.

While Paige continued to endure the horrors of the punishment bag, Sara was headed to see Rachel to talk to her more about the pony girl competition. The more she thought about it, the more excited she was and when she saw Rachel, Rachel filled in the details.

“It is a live, televised pay-per-view event. This year it is in Waco, Texas. The pony girls have to pull a cart with a rider on it for 20 miles on a hot, desert road. But, the owner of the winning pony girl wins $3,000,000.”

“Three million dollars?” Sara repeated, just to make sure she heard correctly.

Rachel nodded her head. “And the pony girl who comes in second.”

Sara was getting very excited just thinking about it. “It sounds fantastic. Great punishment for that slave bitch. But I don’t know anything about training pony girls. Do you?”

Rachel smiled. “Oh, yes. Debra and I have trained pony girls. We could train your slave. It would be so much fun.”

Sara nodded, excited about the thought of Rachel and her sister training little Paige to be a pony girl. Rachel could be a sadistic bitch, which was part of the reason Sara enjoyed being with her, but from stories she had heard, Debra was even worse. That would be perfect.

Sara stuck around long enough to enjoy a bit of Rachel’s sadism and her skilled tongue and then she set about registering Paige in the race. Once she had sealed Paige’s fate, she excitedly went back to the ranch and entered the shed. Sara was delighted to see how frightened Paige looked. She knew that her slave had suffered greatly and she was so excited about the thought of making her suffer more.

With long strides, Sara crossed the floor of the shed and turned off the machine that was connected to the punishment bag. Sara lowered the punishment bag and then stood in front of Paige, who was exhausted and sore from her weeks of confinement. “I have news for you, slave,” Sara said. “Tomorrow you start training to be my pony girl and you’re going to be entered into a pony girl competition. You will win the race. Winning this race is the most important thing in the world to me, so it will become the most important thing in the world to you, too.” Sara’s eyes narrowed to slits as she looked into Paige’s scared face. “If you dare make the mistake of losing this race, I will bring you back to the ranch, tie you to a large barbecue skewer and slowly roast you alive. I’ll feed you to the other slaves on the ranch. Do you understand?” Sara slapped her sister’s face hard.

Fearfully, Paige nodded her head, her brown eyes welling up with tears again at Sara’s cruelty. Sara walked to the door of the shed and flung it open, calling out for the other slaves to come to the shed. “Let her down and clean her up,” Sara said, turning her head back in Paige’s direction. “She fucking stinks.” With that, Sara walked out and the other slaves removed Paige from the punishment bag and took her out of the shed.

Paige was barely able to stand, let alone walk, after being confined for so long. She was assisted by the other slaves who let her lean against them and try to walk out of the shed. She knew that she smelled bad and was ashamed, though it was hardly her fault. Once Paige was cleaned, she was allowed to go back to the slave quarters and lie down. Though the words “pony girl” were stuck in her head, she was exhausted by her weeks of punishment and she fell asleep immediately.

The next morning Paige was awoken by Sara who carried an armful of clothes. “Get up,” she ordered. “You’re going to start training. And put these on. They’re your new clothes. Don’t you dare fucking embarrass me either, you little bitch.”

Paige rose and pulled the clothes on, barely able to believe that Sara wanted her to dress like this. But she didn’t offer a word of protest; instead she put on the clothing. Sara stood and watched her, enjoying her slave sister slide into the skintight clothing. Sara added the final touches and then waited for Rachel and Debra to arrive.

Paige waited quietly, not wanting to upset Sara, who was so excited about the day ahead of them that she was smiling and pacing, anxious for Rachel to come. Debra and Rachel finally arrived and the first thing they did was inspect their new pony girl. Paige was dressed in a shiny black rubber cat suit and was wearing thigh-high spiked boots. Sara had bound her arms behind her in a leather arm sleeve. A hood covered most of Paige’s head, but her mouth was filled with a penis gag. “Not bad,” Rachel said, walking around Paige. “She doesn’t look bad.” Rachel turned to Paige. “Of course that means nothing if she can’t be a pony girl.”

“Unbind her arms,” Debra said. Sara stepped forward to do so and when she did, Rachel took hold of their pony girl and bound her arms up over her head. When Paige was tightly bound, Debra unfurled a large bullwhip and began whipping Paige’s back. Sara could hear screams behind her slave sister’s gag. After a few strikes, Debra handed the whip to Rachel, who also began whipping Paige. Paige tried writhing within her tight bonds, but her hands were too tightly tied. The pain in her back beneath the cat suit was agonizing. Again and again the whip landed against her back. As Rachel whipped, Debra walked behind Paige. “You know, little pony, we will not tolerate any of the crap that you pulled during the Kentucky Derby. You’re going to train hard and you will be punished for every error that you make.” Paige tried pulling away, but she was stuck, unable to move.

Finally, the whipping stopped and Paige was led away from the barn out to a fenced area outside. “First,” Debra said. “You’re going to learn to trot like a pony girl.” Sara watched as Paige stumbled around the area. It was obvious that she was unaccustomed to walking in the spike-heeled boots, but the gag prevented Paige from protesting and even without the gag, she was too afraid of another whipping to raise any objection. Instead, she continued emulating the horses that she so loved riding.

Paige caught on pretty quickly and once she was able to trot like a proper pony girl, she was led away from the exercise yard over to a horse walker. Paige was tied with straps to a large circular machine. Rachel turned on the machine and Paige was led around in circles, forced to walk and keep pace with the machine. At first, it was difficult to pick up on the rhythm of the machine and Rachel and Debra took turns flogging her whenever she made any misstep.

Paige’s legs were aching at the end of the first hour and she wanted desperately to stop, but she had no choice but to keep walking. She was growing tired from the constant pace of the machine, but she kept herself moving by thinking of the whip and of the time in the punishment bag. It had been so horrible, so unbelievably awful that she knew she would do anything to avoid those punishments again.

Paige was released after a few hours and she was allowed to drink water. She was led to a trough and told to drink. When she balked, Rachel pushed her face down into the water. Rachel was thirsty so she drank. She was given food scraps in the trough as well, which she ate up. She wasn’t allowed use of her arms at all; they were strictly bound behind her with arm binders.

For the next two weeks, Paige followed a very rigid schedule set for her by Rachel and Debra. Several hours per day she was forced to go around and around hooked to the walker. She tried to focus her attention on her steps, but the repetition was boring and her mind would wander. Whenever that happened, she would trip or make a mistake and Rachel and Debra were always watching her and would flog her for each mistake.

Paige noticed Sara sitting off to the side, enjoying the shade of a tree. The sun was high and the day was hot; Paige was sweltering inside of her cat suit. With her arms tied, she wasn’t even able to brush away the sweat on her forehead. After her walk, she was allowed water and then she was expected to learn more. Rachel and Debra taught Paige how to gallop and how to jump over small fences. The first few times she attempted that, the heels of her boots caught the fence and she tumbled over. Rachel and Sara both had a good laugh at that and Debra forced her to get up without any assistance, struggling to get up without the benefit of her hands.

Paige was flogged for any mistakes as well. She tried very hard not to make any mistakes, but it was all very new to her. Being a pony girl was very different than riding horses. Because she knew horses, she was able to mimic them, but there was so much to learn.

Rachel spent time teaching their slave proper etiquette, including bowing her head whenever she saw her owner or trainers. Much of her time was spent learning to pull a pony girl cart. The first time Paige was hooked up to a cart to pull, she cried. The pain in her legs was awful and the cart was very heavy. She was in good shape and used to exercise, but the heavy load was nearly unbearable.

Debra, Rachel and Sara decided that Paige’s training should consist of getting her into shape so she can win the pony girl race. She would need strength and stamina and Rachel and Debra were going to train her hard. Sara wasn’t too involved in the training, but she was always present to torment her sister.

Paige’s schedule was very rigorous and she was forced to exercise seven days per week. She was forced to rise every day at 5:00 a.m. and she ate her breakfast from the trough. Then from 6:30 to 8:00 a.m., Paige was forced to pull the pony girl cart around the ranch. It was still very tough for her to do so, but she was grateful at least that part of her training was early in the day.

Rachel and Debra set a treadmill up in the stable and for 2 hours a day, she was forced to trot on the machine at a fast pace. Paige was getting into better shape, but her muscles were sore and stiff from so much running; she was not given any breaks though and she had to keep trotting through the pain.

After her indoor running, Paige was taken back outside and for several hours was forced to walk hooked up to the horse walker. Around and around she ran until her muscles were in absolute agony, but she wasn’t allowed to stop.

As their pony girl ran, Rachel took Sara aside to discuss with her what she and Debra had decided. Rachel stroked Sara’s nipples as she talked to her; Rachel had already discovered that her lover’s slutty little pussy got soaked every time they talked about Paige suffering. “Steroids,” Rachel said as Sara writhed beneath Rachel’s skilled fingers. “We’re going to have to start giving her steroids to increase her speed and endurance.” Sara moaned as Rachel’s finger rubbed her clit. “And we bought a new high tech pony girl suit for her. You’re going to love it.” Rachel’s mouth covered Sara and though Sara was excited to taste her girlfriend, Sara’s thoughts were all on the suffering of her beautiful slave sister.

The next day, Paige was introduced to the high tech pony girl outfit. Debra stood in front of her as Rachel and Sara dressed her and she explained how the outfit worked. “That sensor,” Debra said, pointing “reads a bar code that we place on a stationary object. For example, the horse walker. When our pony is in the outfit, she’ll be expected to keep pace with the bar code. If she ever falls behind, then she gets shocks.” Debra pointed out the shocking wires that were located over every inch of the inside of the suit.

The outfit was powered by a long lasting rechargeable battery which was shaped liked a butt plug, which was inserted into Paige’s tight ass. Moving with the battery was agonizing, but not nearly as bad as the shocking wires throughout the suit. Debra and Rachel shocked her via the remote control several times, just for their own amusement, laughing at Paige’s pain and discomfort.

The outfit and shocking did produce the desired result, however. Paige became much faster and performed more smoothly. The only problem that Debra and Rachel both picked upon was that Paige was bothered by the high body temperature from being forced to run faster and faster.

“We can fix that,” Debra said. “We’ll build up her tolerance.” That night before bed, Rachel and Debra fitted Paige with a very right corset and covered that with a thick rubber catsuit, thigh high boots and her penis gag. Over the gag she was forced to wear a gas mask and her arms were forced into an arm binder.

Over these items, Debra and Rachel placed a huge, leather trench coat on her and then they took Paige down into Sara’s basement where a sauna had been installed. Paige was locked inside of the sauna, forced to endure the horrible steamy temperatures all night long.

The sauna was awful; the heat was unbearable, just as it has been in the punishment bag and Paige tried desperately to free herself but she wasn’t able to move. She felt as though she could barely breathe, trapped in the heavy layers of clothes and with the gag and the gas mask on. She panicked and she had to force herself to calm down. There was no escape from the horrible sauna, just as there was no escape from the training and from the punishment bag. There was nothing Paige could do.

Her days were filled with the painful training and her nights with the horrid sauna. Finally, the day of the race arrived. The trainers and Paige were all nervous as Paige was hooked up to a pony girl cart. Rachel was her rider and she joined a crowd of 200 other pony girls all connected to their carts.

Debra and Sara stood off to the side as Debra explained the race again to Sara. “The pony girls have to pull the cart down this road,” she said, pointing down the dusty dirt road.”

“Dressed like that?” Sara asked, pointing to one of the pony girls. She noticed that they were all dressed alike, including her slave sister.

“Oh yes. To make it much more difficult for them.” Sara and Debra looked at the pony girls dressed in thick leather catsuits, thigh high leather boots with spiked heels and leg irons on their legs which made it difficult for them to run properly. Each pony girl had a penis gag in her mouth and then a gas mask placed over her gag.

“So they all have to go through what we put Paige through?” Sara said.

“Every bit of it,” Debra said and the two women laughed about what the pony girls were enduring. Beneath the heavy rubber catsuits, the pony girls were wearing rubber panties with butt plug and dildos attached to it. Then a tight fitting corset and nipple clamps painfully biting at their nipples. Sara had particularly enjoyed torturing Paige’s nipples before clamping them. Then, the pony girls had their arms bound behind them in leather arm sleeves.

Sara was excited, nervous, but excited as she watched the line of pony girls. Suddenly there was a voice on the loud speaker, as the judges made an announcement. “We’ve decided to make the race even harder for the pony girls. Riders in the pony girl carts may not provide any water to the pony girls until after the winning pony girl crosses the finish line. This also applies to any pony girl who doesn’t finish the race due to heat exhaustion.”

Beneath the layers of clothes, Paige was already sweating. The day was brutally hot and Paige began thinking about water as soon as she was told that it would be forbidden during the race. The starter pistol went off and the pony girls began.

Even after all of her brutal training, Paige found it difficult to pull the cart. Next to her other pony girls stumbled and several succumbed to the extreme heat and fell in exhaustion. Paige began thinking about the threats that Sara made to roast her alive and feed her to the other slaves on the ranch.

Paige continued to stumble along the dirt road, pulling the cart. Rachel yelled at her and whipped her whenever Paige slowed down too much. But with her spiky heels and leg irons, going quickly was just not possible. She was exhausted and so thirsty, but Paige just focused on the many nights that her trainers forced her to sleep in the sauna. It had been so awful and Paige had felt like she couldn’t breathe, but now she was grateful for that cruelty because she was still standing and was one of only three pony girls left in the race.

“Just go, just go, just go,” Paige thought to herself, repeating the words. With every step she took, the plugs in her ass and pussy moved. She couldn’t move her arms and felt as though she could barely breathe within the gas mask. The whole race was extremely sadistic and Paige couldn’t wait to get to the finish line. She concentrated on just taking the next step. Hot. So hot, she thought to herself. She imagined that she was back in the horrible punishment bag, suffering endlessly. She had survived that and she would survive this, the heat and the confining clothing. She limped along the road in her shoes, trying to drown out the noise of the crowd.

With only one quarter mile left in the race, Paige pushed herself. There was only one other pony girl in the race and Paige watched her running. Paige couldn’t see her face since all of the pony girls had to wear gas masks that covered their faces and kept them from really seeing each other well. The other pony girl, Gretchen, kept her attention focused on Paige, trying to ignore the heat and thirst and exhaustion. Both pony girls were suffering, barely able to keep on their feet, but other girls were being viciously whipped by the riders in their pony carts. Both Paige and Gretchen cried out from behind their gags.

The pony girls were stumbling in their shoes and with each agonizing step, drew closer to the finish line. Paige stepped over the finish line and she saw Gretchen next to her. Her heart beat wildly in her chest, both from the incredible feat she had just undertaken and the fear that Gretchen might have somehow finished the race before her.

The two pony girls were forced to stay with their carts while the judges reviewed the film footage of the finish. None of the pony girls were allowed to drink or be unhooked from their pony carts until the judges made their decision. After careful review, the judges declared pony girl Paige the winner.

Sara and Debra ran to the cart and Sara threw her arms around Rachel, kissing her and congratulating her. Several of the spectators who had been lined up on the side of the road, sitting on blankets and sipping water also ran over to Rachel to congratulate her. She smiled and laughed, happy that the training of their useless pony girl ended up working out for them.

The judges announced the winner again as Rachel was handed her trophy. Sara was given the reins to Gretchen, the pony girl in second place and Sara received the check for $3,000,000 in prize money. The girls, excited, talked about what they were going to do with the money and soon the other pony girls were being led away. Sara watched as Rachel and Debra talked. She was certain that several of the pony girls faced punishment for their failures.

Sara led Paige and Debra led Gretchen back to the stables. The girls undressed their pony girls, noticing that both pony girls were covered in sweat, making their thick layers of clothing stick to their bodies. It had been a very brutal competition and Sara, Rachel and Debra took turns spraying the girls with a high powered hose. The water was cold, but the pony girls both enjoyed the feeling of cold after the brutal heat of the day. Paige’s dark skin contrasted with Gretchen’s pale skin as the pony girls stood side by side.

Debra and Rachel filled the pony girls’ trough with food and water and the exhausted pony girls ate and drank. When they had finished, Paige looked longingly at the stable, wanting nothing more than to lie down. She didn’t think she had even been this tired when she was in the punishment bag. But their owners had other plans for the pony girls.

“Come here,” Rachel said to Gretchen, their new pony girl and Gretchen obeyed, walking up to her new owner. Rachel attached a harness to Gretchen and a strap-on dildo was attached to the front. As Paige looked on, Rachel secured the straps and then Paige was fitted with a similar strap-on.

Rachel lay back on a blanket and she pulled Gretchen down on top of her, making it clear to her new pony slave that she expected to be pleasured. Gretchen eased the dildo inside of Rachel’s wet cunt. Though she was exhausted, Gretchen moved her hips, wanting her owner to have a favorable first impression of her.

Sara instructed Paige to lay down on the blanket next to Rachel’s blanket and Sara eased herself down on the dildo protruding from Paige’s harness. Sara leaned down and hissed in her sister’s ear “Fuck me.” She pulled Paige’s hair as Paige moved against her, grinding her hips against her half-sister.

As Paige moved, she heard Rachel next to her explode in orgasm. Debra took her place and then soon Sara’s own orgasm came. The girls took turns being satisfied by their pony girls, first with the dildos and then with their mouths. When Rachel, Debra and Sara were finally satisfied, they locked Gretchen and Paige in the stable where the pony girls fell deep into sleep.

Sara, Rachel and Debra left their pony girls to go out to a local bar and celebrate. The girls drank beer and danced late into the night. In the morning when they finally awoke, they loaded the two pony girls into the trailer and drove them back to the ranch.

As Rachel and Debra took their new pony girl out for a run, Sara stayed behind to play with Paige. Sara whispered into Paige’s ear. “I hope you liked all the clothing and gear you wore at the race because there will be a lot of that in your future. No freedom for you, my little pony girl.” Despite the warmth of the day, Paige felt a chill run through her.

“But I thought . . .” Paige began.

Sara laughed. “Since when do you think?” she said as she began binding her sister’s arms behind her. “You’re here at our mercy. Our pony girl. Tight bondage. For our pleasure. Forever.”
