The next morning Naruto led Sakura out behind the house. He pointed the start of a hardened dirt path that was heavily hidden by trees on all sides. "The whole path is about five miles. But there a shortcut back about halfway that cuts the trail in half." He led her to the western edge of the back yard. It was a large yard, cleared of all the trees except for one large willow in the middle. The whole yard was covered in a carpet of thick soft grass. Sakura could imagine herself sitting out here, maybe playing fetch with Karin, while her other slaves worshiped her feet and she cuddled with Ino. At the far western end of the yard there was a good sized barn. There were no windows, and the only door had two locks built into the door, then a padlock. Naruto unlocked the door and handed Sakura the keys. On the left side there was one long stall that was about half the length of the barn. On the right side was a stall the same length but it was broken into three. "The back area here is the training area. The left stall is meant for the lead mare, and the right side is for the others. The passenger carriages are usually meant to be pulled by three pony's. So if you fill all the stalls you'll have an extra in case you wear one out. But your personal carriage is designed to only need to be pulled by one pony, usually the lead mare." "The carriages are outside under the big awning." Sakura ran her fingers along the fence of the lead mare stall. "Naruto this is amazing, and I already know the perfect girl to be my lead mare. Come with me." Sakura said grabbing his wrist. She had always loved the way Pony Girl outfits looked, she had seen Becky in hers a few times, but they had never had enough room for one before. Sakura rushed upstairs and went into the hidden space of the closet. She grabbed one of her I.O.U.'s out of a locked drawer and rushed out of the house, Naruto trailing behind. They arrived at the village, and Sakura rushed right to the Hokage's office. She slapped the note down on the desk and told Tsunade what she wanted. Tsunade smiled and led her down to the Hokage's private holding area. She told Sakura to wait outside, then went into Tayuya's holding cell. Tsunade came out a few minutes later with Tayuya's limp body flung over her shoulder. "She should be unconscious until tonight, so you'll have time to get her ready for whatever you want her for." Sakura took Tayuya and met Naruto outside. They stealthily headed to the kink shop. Rachel let them in and they headed to the back to find Sarah. "Oh hey Sakura how's it been going? We haven't seen you in awhile." Sakura set Tayuya down and hugged Sarah. "We've been moving into a new place. You have to come see it soon, you're going to love it. But that's not why I'm here today. Can you measure her for a Pony Girl outfit? I want the best of everything you have." Sakura said slapping down a wad of cash on the table. "Alright Sakura, I think you're in luck. I just finished one of the best sets I've ever made, all the rings are made of solid, engraved gold, the leather is red and the softest I've ever worked. The gold is all reinforced with chakra so it will never bend or break. I'll even include a set of weighted training boots for free." Sarah went to the back and pulled out a pile of gold rings and red leather straps, as well as a pair of pony boots. "Everything is really close to her size, I should just need to adjust a few things. It should only take about an hour, do you want to wait here?" Sakura sat down and waited patiently, stroking the unconscious Karin's hair. Sarah brought a black leather bag back to Sakura. It was full of the Pony Girl stuff. "Careful this is kind of heavy cause the weighted training stuff is in here." Sakura thanked her and Naruto picked up the bag. They snuck out of the village with the naked Tayuya slung over Sakura's shoulder. And made their way swiftly back to the house. Sakura carried Tayuya out to the barn and set her down in the training area. "Naruto go let the girls out of their cages, they've been locked up all day. When you're done with that meet me back here, I might need your help with her. Sakura rested Tayuya's head in her lap and stroked her hair while she waited for her to wake up. Tayuya woke with a start, confused by her surroundings. When she saw Sakura she calmed down a little. Tayuya sat up, directly across from Sakura and studied her for a moment. "You got me out of that prison?" Tayuya asked confused. Sakura only nodded. "Why" she asked, suspicious. "Well I decided I could put you to better use, instead of just letting you rot in that cell." "What do you expect me to do for you?" Tayuya said at length. "Very simply. I expect you to be my lead Pony Girl. In exchange, you will be fed, housed, and taken care of to the best of my abilities. Also, if you behave you will be rewarded with pleasure. That's my offer, if you decline I can always take you back to the Hokage's prison." Tayuya thought about it for a long time. She remembered how Sakura showed her mercy when the Hokage would have just as soon have had her tickled unconscious. "You promise you'll be nice to me? And you wont hurt me?" Sakura nodded. "I promise I will never hurt you, unless you do something that is worthy of punishment." Tayuya sighed. "Alright, I guess I'll give it a shot." Sakura got up and retrieved the bag of supplies. Tayuya sat on the ground. Looking nervous but accepting. The first part of the outfit was the black hoof boots. They made it so that Tayuya had to stand on the balls of her feet. Sakura helped her stand. The boots helped to show off her muscular calves. Tayuya wobbled for a moment while she got used to the boots. Sakura pulled out a butt plug tail, and started lubing the end. Tayuya submissively bent over to give Sakura better access. Sakura did her best to slide the tail in gently. After the tail was in, Sakura picked up the red leather harness. The harness was designed to keep the tail in place. It also had straps on either side of her pussy, so that one could still access it. More straps ran across her torso, and above and below her breasts. The back of the harness had thick metal rings, for pulled a carriage. Sakura pulled out a black leather arm binder and slid Tayuya's arms into it. As Sakura was tightening it, Naruto knocked on the front door of the barn. "Mistress do you need anything?" "No Naruto I'm fine. Go back inside and relax with the girls." Sakura made sure the arm binder was snug, but far from uncomfortable. Sakura put a thick leather collar around her neck, not quite as wide as big as a posture collar, but still bigger than a normal one. "How's that?" Sakura asked running her hand down Tayuya's mostly naked body. Tayuya pranced around a little and smiled. "I actually sort of like it." "Good, I'm glad. Now lets test your strength." Sakura guided Tayuya over to a thick metal pole sticking out of the ground. There was another thick pole sticking horizontally out of the first at roughly chest level. Sakura clipped a bunch of straps from the horizontal one onto Tayuya's harness. "This device is to measure your strength as a Pony Girl. I've been told most girls can hand up to setting eight at first for about fifteen to twenty minutes without passing out or straining themselves. Tayuya simply nodded that she was ready. Sakura turned the machine on setting eight, and Tayuya started walking forward. She managed to pull setting eight with little issue, so Sakura turned it to ten. Still Tayuya pulled on. Eleven, then twelve. Twelve is when Tayuya slowed a little. Sakura sat down in the chair in the corner to watch. After thirty minutes Tayuya stopped. Sakura helped her to the ground, then used chakra to help her recover. After Tayuya had recovered, she looked up into Sakura's eyes. "How did I do " Tayuya said with a smile. Sakura kissed her on the forehead. "You made me very proud. You handled four setting higher than average for ten minutes longer than average on your first day." Sakura took off her normal hoof boots, and replaced them with the weighted ones. Each boot weighed twenty five pounds. Sakura helped Tayuya stand. "You are going to wear these training boots five days a week, on Saturday and Sunday I will let you wear the normal ones." Sakura reached into the bag and pulled out the last item. It was a black bit gag "One last thing. Pony's can't talk. You will wear this, all day, every day. For a few hours each night I will sit with you in your pen and talk to you. But you will talk to no one but me, understood? Tayuya nodded. Sakura led her outside. Tayuya was a bit embarrassed, but Sakura comforted her. "Alright, I know you're tired, but I have one more test for you. If you can make it to the halfway point on the trail and and back, I will let you rest for the remainder of the day, and reward you." Tayuya nodded, and started jogging. Sakura was surprised that she could lift her legs enough to jog, but was also proud. Tayuya would make a good lead pony. Tayuya made it back about half an hour later. Sakura helped her walk to the barn, and laid her down in her stall. Sakura took off the weighted boots, Tayuya had done well, she deserved a rest. Sakura pulled Tayuya up, until she was sitting between Sakura's legs. The floor of the pen was covert in a padded futon mat, instead of hard dirt like real horses had. Sakura hugged Tayuya to her chest, and slid her hand down between her legs. Tayuya would be wearing the arm binder almost all the time now, so she would be unable to masturbate. Her only source of pleasure would be Sakura. While Sakura's finger slid in and out of Tayuya, she undid the bit gag. Tayuya moaned at the freedom. "Thank you so much Mistress." Sakura simply kissed her on the cheek as she came. Sakura sat with Tayuya awhile longer, and they talked. "So what do you think of your new life?" Sakura said while she held Tayuya and stroked her hair. "It's wonderful Mistress, I think I actually enjoy being a Pony girl. Thank you so much for saving me." "You're very welcome, it pained me to see such a beautiful girl wasting away like that. Now you get some rest, I expect you to run the track again tomorrow. But I'll let you use the normal boots since you did good on your first day, I expect you'll be sore tomorrow anyway." "I'm going to leave your boots and gag off, since horses don't sleep in their bits. But remember, don't talk to anyone but me. You're a Pony now, I expect you to respond like a Pony." Tayuya neighed and tossed her mane of thick red hair from side to side. Sakura smiled at her as she closed the barn door, and locked it.
