"How's my pretty pony this morning?" asked Linny as she stood at the door to the stall.
"Miserable," replied Faith. "You have to let me out of here. What you are doing is illegal."
"Oh, it's not illegal," said Cinny. "We're just three teenage girls having some fun."
"I'm not having fun," said Faith. "And yes it is illegal. It's called kidnapping."
"But you haven't been kidnapped," argued Linny. "You are still living with us."
Faith gave up hope of winning this argument. It was clear that the girls were not going to let her go. She would just have to find the right time to escape. "I'm filthy. I need a bath."
"Yeah, you have looked better," said Cinny. "But ponies don't take baths."
"What's all of this nonsense about ponies?"
"You are our pony," responded Linny. "Our beautiful pony."
"I don't even know what that means," replied Faith. "You aren't making any sense."
Linny explained what she meant and Faith grew more irate with each new revelation. She was not going to be treated as human. She was going to live in a stall. She was going to be exercised and raced and shown. "It will be lovely. I think it must be most exciting to be a slavegirl."
"I've had it with you two," Faith said angrily. She pointed a finger at one girl and then the other, causing her breasts to jiggle as she moved. "Open that door this instant!"
"We were planning on opening the door, silly. You don't have to get mad at us."
"Well, it's about time," said Faith. "This has gone on long enough." She stepped to the door, crossing her arms and tapping her bare foot impatiently.
"Now just turn around and give me your hands," said Linny.
"What!?!?!??!" said Faith, indignantly.
"Yes, pretty pony," said Cinny. "Until you are tamed, we need to keep you harnessed."
"Forget it!" responded Faith. She stomped to the far end of the stall and sat down on her bale of hay. "You two are nuts!"
Faith missed the next two meals and was starved by the time dinner rolled around. Plus, with the heat and the dirty stall, she felt unclean. It was a miserable state of affairs for her: starving and filthy. When the girls showed up at dinner time, she tried to reason with them again. When that failed, she tried to negotiate. They would not budge, however. In the end, she found her wrists held behind her back by steel cuffs.
The girls marched her out of the barn to an outside shower. There, they stripped themselves so they would not get their own clothes wet and Faith found herself blushing as she saw her younger cousins naked for the first time.
They turned on the water and pushed Faith under it, following until one was in front of her and the other behind. Faith had expected the water to be cold but was pleasantly surprised to find it comfortably warm.
The girls wet her hair and then worked the shampoo in together, raising a sudsy foam in the long auburn locks. They rinsed out her hair and then repeated the shampooing. They worked the bar of soap in their hands, creating a new foam and then used their bare hands to spread the soap over their captive's body.
Faith suspected that Cinny would pay too much attention to her breasts and she was right. She squeezed and manipulated the fleshy mounds, resoaping her hands several times before she seemed to think that they were clean enough. Both girls crouched down and soaped up the legs, starting at Faith's feet and working their way up. Faith was completely unprepared for what happened next, though. She felt a hand covering her sex with a finger parting her labia at the same time she felt one of Linny's soapy fingers pushing down they valley between her bottom cheeks.
"Hey!" she shouted at them. "Get out of there! Both of you!"
"Gotta clean the pony," giggled Cinny. Faith twisted and tried to move away but Linny grabbed the cuffs and held her in place.
"We can always tie you up more for your showers if you would prefer," said Linny. Faith stopped struggling for fear of more severe bondage.
Cinny softly stroked Faith's petals for awhile, smiling as she felt them becoming slick with arousal. Faith closed her eyes in shame as another girl touched her so intimately. After awhile, Linny's finger started moving again and stopped to tease Faith's little pucker each time the finger passed through the forbidden valley.
After a few more passes, Linny soaped up her hand again and pressed the tip of a finger to the little rosebud. She kept pushing harder and harder until the little pucker finally yielded. Then she sawed her finger in and out of Faith's bottom as Cinny started plunging her finger in and out of the captive's sex.
Faith protested again but was immediately silenced when each of her bottom cheeks and each of her breasts were spanked harshly. She stood silently while her two younger cousins had their way with her vulnerable body. It did not take long for the girls, working together, to steal an orgasm from their captive. They both squealed in delight at what they had accomplished, seeing Faith tense and hearing the soft moans.
