As the sun slowly climbed into the sky, the light shone through the windows of Carousel Boutique, revealing the enlarged belly of Rarity. At first glance, the fashionista appeared to be a couple weeks overdue with triplets. The only thing was that Rarity had never been with a stallion. She had flirted with some on occasion but nothing serious. Rarity continued to sleep until a shout came from her large stomach.
"RARITY." yelled a young filly.
Rarity mumbled and merely turned over to her other side, causing the voice to call out even louder.
"RARITY!!"
The purple maned mare jolted awake at that and looked down towards her belly somewhat upset.
"What is it Sweetie Belle? Do you know what time it is?" asked the fashionista placing a hand on her enlarged belly.
"It's time for you to let out. I have school today." replied Sweetie Belle.
The alabaster unicorn mentally groaned as she rolled out of bed with some difficulties, due to the added weight of her little sister. Four months ago, Rarity discovered a hidden ability that allowed her to keep other ponies in stomach unharmed. The way this talent was brought to light was by accident. Sweetie Belle was trying to help as always, when the young filly slipped off a ladder and into her sister's open maw. The forward momentum was enough to send the young unicorn straight down to Rarity's waiting stomach. It took several moments before the fashionista realized what happened. Rarity quickly headed over to Twilight's castle to help get Sweetie belle out. During the trek over to the crystalline building, Rarity noticed how pleasurable it was to have somepony else in her belly. She could do without all the squirming though. Once at the castle, Rarity quickly explained what happened to Twilight, who was indeed able to safely remove Sweetie Belle from the fashionista's belly. The moment she was out, Rarity hugged Sweetie Belle and apologized for what happened. Sweetie told Rarity that it was fine and it was an accident. Later that day, the sisters sat down to talk of what had occurred. Rarity was little surprised that Sweetie Belle had somewhat, enjoyed being inside her belly. Claiming that, it was like being in their mother once more. Sweetie Belle went on to suggest that try it again that every night. That made Rarity a little uneasy, but agree on the condition that if it turns to be dangerous. They would get her out and never attempt it again.
Since then, Rarity had discovered that she sleeps a lot better when she had somepony in her stomach. Especially when, she learned from Twilight, that she had the ability to whole ponies in her belly for an infinite amount of time, without digesting them. Or having running out of air. It was an ability that showed up every couple of generations in each pony race. Sweetie Belle however, was getting tired of bring the only one to her big sister "ATE" nearly every night. Once their morning routine was done, Sweetie Belle headed to school, while Rarity made her way upstairs to her workroom. As the progressed, Rarity was able to finish some her major projects, while Sweetie Belle was enjoying hanging out with her friends. Rarity had just put the finishing touches on a dress for Fleur de Lis, when she heard her younger sister return.
"Hey, Rarity. I'm home." called Sweetie Belle as she headed to the kitchen.
After making sure the jewel was in place, Rarity made her way downstairs. The two sisters spent the last bit of sunlight talking about their day as they ate dinner, before getting ready for bed. As Sweetie Belle slipped into nightgown, the young unicorn couldn't help but wonder how her life ended up like this. While yes, it was her idea at first. But Rarity had taken it a little far. She barely remembered how sleeping in her own bed felt. Sweetie wouldn't mind so much, if she had some company while in her sister's stomach. Sweetie Belle's face suddenly lit up with excitement at that thought. Naturally, she would have to run the idea past Rarity first. Sweetie Belle quickly finished getting ready and headed to Rarity's room.
"Ready for bed, Sweetie?" asked Rarity as soon as her sister enter the room.
"Yes I am, Rarity," replied Sweetie Belle with a small smile.
"You seem somewhat energetic tonight. Is there a reason why?" questioned the seamstress.
Yeah, but it can wait until morning." answered the younger unicorn.
Rarity was going to press further, but changed her mind at the last second. The sisters made their way to Rarity's bed where, the fashionista sat down so that she could swallow Sweetie Belle easier. Once Rarity had opened her mouth, Sweetie Belle gently inserted her arms. It only took a couple of minutes before Sweetie Belle was fully inside of Rarity's stomach once again. Rarity could only blush as she felt her sister move slightly to find a better sleeping position. Despite not being a fan of Sweetie Belle around so much, Rarity would emit that sight of her abdomen lightly moving was a little relaxing. Sweetie Belle spent a minute or two before she sitting right-side up.
"Good night, Sweetie." said Rarity placing a hand on her enlarged belly, once she had settled into bed herself.
"Good night, Rarity." replied a muffled Sweetie Belle.
As Sweetie Belle fell asleep, the young unicorn thought about exactly who would be joining her in Rarity's gut. Sweetie Belle made her decision in the final seconds of consciousness. Meanwhile, Rarity gently rubbed her stomach as she felt Sweetie Belle drift off to dreamland. The seamstress soon felt sleeps embrace herself, which was her cue to turn off her bedroom light. Rarity took one final glace at her belly before turning off the light. The sight brought a small blush to her face. Little did she know, Rarity would be hosting two fillies in her stomach instead of just one as she fell asleep.
