"Mom called last night," announced Linny. "We told her you were taking good care of us."
"She didn't want to talk to me?" asked a surprised Faith.
"Oh, she did. We told her you were sleeping. And she said she would be gone another week; something about complications."
This was not good news at all for Faith. She felt her heart sink at the knowledge that her ordeal was to be extended. She would just have to work harder at finding a way to escape. But so far, there hadn't really been a chance. She had either been locked in that escape-proof stall or had her arms chained together behind her back. Even if she ran, she would not get far and she would be easy to overpower.
It was very good news for the twins. They would have much more time to tame their cousin now. They sat up late, refining Plan B to take advantage of the extra time before they made love and then went to sleep together in their warm, cozy bed.
"You have to let me go, then," pleaded Faith. "A week is too long to keep someone locked up."
"Oh, a week is not long at all," said Cinny. "It will be over before you know it."
"And you'll have lots of fun," added Linny. "You seemed to enjoy your little orgasm yesterday."
"That was awful!" complained Faith. "I still can't believe you did that to me!"
"It didn't look awful to us," said Cinny. "It looked like it felt pretty good. And you are so beautiful when you climax. We'll have to do a lot more of that."
The other thing the girls did the night before was to figure out the pony harness. They knew it would work because they had seen some of their mother's girls prancing around it the harness but, at first, they could not make any sense out of the jumble of straps. They finally decided to test out the harness on one of them and Cinny was selected.
"You should take off your clothes for this," advised Linny.
"I'm sure it would work with clothes on," replied Cinny.
"Yes, but we want to be as realistic as possible. We don't want to be fumbling around on Faith."
"Ha!" remarked Cinny. "You probably just want to feel me up."
Linny laughed. "I don't need you in a harness to do that. I do that every night." Cinny finally relented and took off her clothes. Linny started laying the straps over her sister and then turning the harness. They bickered back and forth as Linny worked with Cinny providing advice and Linny arguing why that wouldn't work or saying that she already tried it. Finally, they figured it out and Linny started adjusting the straps to fit the harness.
"You look so sexy as a pony," said Linny as she stood back and admired her sister. Jane had several harnesses in different colors and they had chosen the plain brown leather one to start with, thinking that it would go well on their auburn haired cousin.
"Thanks, but I'm not sure that we've got it right yet," Cinny reached up and tugged on the straps that encircled her breasts. They were loose.
"I tightened it as much as I could. It will be snug on us in a year or two. It's just made for better endowed girls than us. It will be perfect on Faith."
Linny led her sister to the mirror and let her see herself. "Yeah, it does look sexy. I can't wait to get Faith into it."
"Let's try out the other stuff," said Linny.
The bit and bridle turned out to be just as confusing as the harness had been. The bit itself was easy enough but figuring out the straps to the bridle was a challenge. They eventually got it sorted out though.
The girls had debated whether or not to cuff Faith's wrists to her harness or use an armbinder, although that had been an earlier debate. With the bit in her mouth, Cinny was in no position to debate anything. They had decided to use an armbinder on their cousin since it was more severe. That way, she would appreciate it on days when she was simply cuffed.
The armbinder turned out to be easy to slip onto Cinny. Because of her youth, she was very flexible. And she was not as large as the girls the thing was designed for.
"One last thing," announced Linny as she held up the tail and grinned.
"Rai, rai!" Cinny tried to say around the bit that was preventing her from speaking. Linny wasn't exactly sure what she meant but interpreted the desperate plea as "Wait, wait."
"We have to check out everything," explained Linny. "This won't be bad."
Cinny had panic in her eyes as her sister advanced on her with the plug in one hand and a jar of lubricant in the other. Linny circled her sister and Cinny kept turning to keep her bottom pointed away from Linny. Linny finally realized that she would need both hands to fit the thing and stopped. She dipped the end of the plug into the lubricant and then held the other end in her teeth, letting the tail drape down her cheek.
With both hands free, it was easy to catch and subdue her bound sister. Linny dragged her over to the bed and bent her over the edge of it. Cinny kept her bottom cheeks clenched together and wiggled as much as she could. But with Linny sitting on top of her and prying her cheeks apart with her free hand, she was easy prey. Linny placed the tip of the plug at the cute little rosebud and twirled it to spread the lubrication. Then she slowly pushed it in to the grunts and pleadings of her sister.
"Let's see how it all looks," said Linny as she climbed off the bed and helped Cinny up. She led her sister to the center of the floor and then slowly circled her, trailing her fingers over the straps and naked flesh. She eventually stopped and faced her sister. She leaned forward and kissed the tip of Cinny's nose as she lifted her hands, placing her palms over her sister's exposed breasts.
"You are such a pretty pony," she said. "I might just have to change the plan." Cinny shook her head furiously and mumbled some loud complaints. Linny couldn't understand anything that was said but assumed that, whatever it was, it was laced with expletives. Linny smiled and lowered her hand to Cinny's sex and stroked the petals that were amazingly slick and the little pearl until she gave her sister a powerful orgasm.
"Don't worry," said Linny as she started to loosen the harness. "I already have a pony. I like you better as a sister. But it's true that you look delicious as a pony."
The harness was removed and then the bit and bridle. "That was so cruel!" complained Cinny once she could talk again. "Get that thing out of me!"
Linny laughed and went behind Cinny. She grasped the tail and pulled the plug half way out but then pushed it back in, causing Cinny to groan.
"Don't!" cried Cinny as she felt her bottom filled again. "Stop!"
Linny experimented and kept sliding the plug in and out of her sister's bottom. Cinny kept protesting until the protests faded away to a series of desperate moans. Linny recognized the moans as a sign that Cinny was close to climaxing.
"Don't stop," moaned Cinny. Linny reached around her captive to start stroking her clitoris. It did not take a lot of stroking to push Cinny into another powerful orgasm.
"You are so cruel!" exclaimed Cinny once she had recovered enough to speak coherently. In the meantime, Linny had pulled the plug out and removed the armbinder, leaving Cinny completely unbound. "Faith is going to hate this."
"Oh, it didn't seem like you hated everything about it," smirked Linny as she wiggled the finger that had just inflicted two earth shattering orgasms on her sister.
Cinny blushed. "Well maybe not everything was horrible," she said and then giggled. "Maybe she won't mind it that much."
