"Good girl," said Cinny as she caressed and squeezed the soft mound. Linny stepped closer and claimed the other breast, lifting it with one hand as the fingers from her other hand danced over the warm, smooth flesh.
"Pretty pony," said Linny as she enjoyed the perfection that was in her hand. "Isn't this so much better than starving and thirsting? We want to be good to you. You just need to let us."
Faith was finally able to eat her first meal in over a day. The girls kept her in her stall. Faith was required to stand at the bars with her hands locked behind her head. This caused her breasts to be displayed even more prominently, much to her chagrin, and made them easy targets for the girls. The twins fed their captive as the offered breasts received attention. When the meal was finished, the girls started to leave again.
"Wait!" Faith called out. "You're not going to leave me here like this, are you?"
"But this is where good little ponies are supposed to sleep," said Linny.
"Maybe we'll take you out for some exercise tomorrow," added Cinny. "If you're good for us." Then they left, turning off the light on their way out. Faith spent another sleepless night curled up in her cold stall.
Chapter 5
"Tell me again about Plan B," said Cinny. Both girls were naked and were curled up in bed, spooning. Linny was behind her sister, holding her, as her hand slowly caressed her.
"Well, it just came to me yesterday. Plan A was to slowly wear her down. First was the constant touching. Then, we're going to move her to constant nudity. After that, we were going to going to make her totally dependent on us. And voila. We have ourselves a ponygirl."
"Yeah, I know all about Plan A," said Cinny as she felt her sister's hand glide over her naked body. "What was wrong with it?"
"It takes forever," replied Linny. "We would have been working on her all summer. And Mom would be sure to figure it out eventually."
"Mom wouldn't object, would she? She's had slavegirls of her own. She'd have to expect us to want one." It was true that Jane had slavegirls before. That was the main thing that led to the divorce. When it started, which was before the twins were even born, it had been more of a hobby. It was just recreational fun. As the years progressed, however, Jane spent more time with her subs and slaves and less time with Frank. She knew all along that she was bisexual but finally realized that, in reality, she was lesbian. There was no room for a male in her life.
"I don't think that she would mind us having our own girl," replied Linny as she slid her hand up Cinny's belly to cup one of the firm, developing breasts. "But I think she would mind us enslaving our cousin; family relations and all that."
"Oh," sighed Cinny as she enjoyed having her breast held. "Maybe. So how did this plan pop into your head?"
"Well," explained Linny. "She was right where we were going to put her eventually; in a stall. And she was already almost naked, just like we were going to make her. I just skipped months of conditioning."
"Seems kind of risky to skip all of those other steps."
"It might be," agreed Linny. "We'll have to be harsher than we had planned. But unless Mom comes home right away, we should be able to break her. And once we've done that, it will be too late to release her."
"So how do we break her?" asked Cinny.
"I haven't figured all of that out yet." Linny's finger was toying with her sister's nipple now, rolling it back and forth and causing the delicious bud to stiffen. "We've already started. We deprive her of food and water and she only gets either when we are playing with her body."
"I think arousal and relief should be part of it too," Linny continued. "If we keep her constantly aroused but only let her climax with us, she'll start to need us."
And then she went on. "We'll have to punish her when she misbehaves too. I think it will work."
"I sure hope so," said Cinny. "She's just so beautiful. I'd love to own her."
"You will, sis," assured Linny. Then she rolled her sister toward her to kiss her. They embraced as they kissed and made love before drifting off to sleep in their warm comfortable bed.
Chapter 6
"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.
