The Book of Friendship

Withania entered the throne room for Canterlot Castle with her folder of ponies flopped over her back. The room was large and ornate, illuminated in watercolour from sunshine beaming in through stained glass windows. Ahead of her was a flight of stairs up to the thrones themselves for Celesta and Luna, where stood Celestia herself with two guards and three official looking unicorns discussing stately matters.

“As always, good communication is the key to maintaining these relationships, I’m glad we’ve been able to strengthen ties with the independents.” Celesta paused for a moment as she saw Withania approaching the base of the steps to wait her turn. “Excellent work everyone, we’ll take a break this week and convene next Tuesday to follow up this progress. That will be all.”

The unicorns shuffled their paperwork and bowed before departing, murmuring amongst themselves as they passed Withania.

“Miss Nightshade, this is an unexpected pleasure,” said Celestia. “Guards, if we could have some privacy for a moment, thank you.”

The guards now also departed silently. They glanced at Withania, wondering what business she had with the Princess that warranted secrecy, but said nothing.

“Ah, yes I wasn’t sure if you wanted me to call in advance or not… but uh, I succeeded! H-here!”

Withania shrugged the folder off of her back and held it out in front of herself, not entirely sure if she should just show off her achievement or not. Celestia looked somewhat confused, but picked up the folder with her magic and held it in front of herself. Her eyes widened as she opened it and saw the elements of harmony arranged as pages - not in shock, mind you, but intrigue.

“Withania, this is…” Celestia closed the book, speaking over it in hushed tones.

“You said bring them all together, right?” said Withania, smiling awkwardly as she suddenly realised the strangeness of what she’d done.

“Withania dear, I was more thinking of a sleepover or something. A pizza party lock-in at the town hall maybe…”

“Uhhhhh…” Withania began to fret, but Celestia’s mouth curled into a sly smile.

“However, this is quite impressive. I’m quite sure I can come up with some festivities to introduce the girls to while they’re all… gathered, like this.”

“Ah! Excellent!” exclaimed Withania, wiping her brow with mock relief before turning as if to leave. “Well, happy to be of assistance - you know where to find me!”

“Well there is one more thing,” said Celestia, reaching an enormous wing out to behind Withania’s shoulder. Suddenly placed within touching distance, Withania glanced up and became acutely aware that Celestia was about twice her size. “I must admit I suspected you were up to something unorthodox, as there have been rumours going around of the Elements disappearing and you being somehow involved.”

“I’ll be sure to keep a low profile,” said Withania, “I’m pretty well stocked at home, and I’ve got a few well-connected friends I could hide out with if needs be-”

“Oh I’ll take care of this,” cut in Celestia, with a knowing smile. “After all, you’ve gone to a lot of trouble, it’s the least I can do. Stay right where you are for a moment…”

Celestia stood up and turned around, seemingly to place the folder of ponies behind her throne. Her large and curvaceous flanks now loomed before Withania who wanted to back up slightly for personal space, but stayed firmly where she was, thinking she was about to get teleported and whisked away somewhere.

Don’t oogle the Princess, don’t oogle the Princess, pleaded Withania with herself as Celestia’s shimmering tail brushed across her face. Yet, almost as if challenging her, the same shimmering tail lifted to give a clear view of the tremendous alabaster orbs - which began to rapidly descend toward Withania.

Confused and uncertain as to exactly what was happening, Withania automatically raised her forelegs up, as if she were going to catch the huge alicorn. Her hooves met the royal flanks, hitting a layer of impeccably soft pudge, but behind the pillowly touch was an impossible weight. Withania braced to take the strain, but for all it was worth, Celestia might as well have been made of cast iron.

With zero resistance, Withania began to crumple, her face hitting the same delightfully soft, yet deceptively dense hind quarters. If she had been ready, she might have been able to twist aside or fall backwards - but with her own rear parked on the floor, Withania was stuck between a hard place and Celestia’s unstoppable posterior. She had a moment to realise what was about to happen just before her body had compressed as far as it naturally could.

“Huurrmmmfff!” Withania’s yelp was muffled as she was squashed flat in a single smooth motion. Celestia was barely pushed off-centre as the earth pony vanished under her bulk. Only the tips of Withania’s forehooves could be seen poking out under her cutiemarks in a vain attempt to save herself. The princess looked over her shoulder with her tongue just peeping out from between her lips, pressing her thighs back slightly to finish the job. Withania felt her body smushed back, lengthening a little so her hind legs were between Celestia’s thighs while her head and shoulders were hidden just under the dock of her tail.

“I must admit,” said the princess, slowly standing again, “I do enjoy throwing my weight around a little, but it’s not until today that I’ve thought to push the envelope this far…”

She turned to admire her hoofwork, and saw Withania spread out on the floor. Her head was flattened into her neck and shoulders, leaving her forelegs sticking out on either side. With her legs spread downwards, she could easily have been mistaken for a cartoon letter “T”.

“Now for some finishing touches, my dear…”

Withania felt Celestia’s magical aura envelop her, and she was gently peeled up off of the floor. She tried to move her limbs, but while her muscles tensed, she had no strength to actually move herself. Celestia carefully brought Withania’s forehooves around to meet her hind hooves, and the flattened pony watched in confusion as her extremities merged together into a seamless band. Next a tingling sensation, almost like popping candy on her tongue, spread around the edges of her flattened body, and a pattern in the same tan-colour as her hooves appeared as if invisible needles were stitching into her, leaving a lace edge in their wake. Finally, a ripple spread from her middle across her up chest and down the flat band that used to be her hind legs, as well as along her forelegs that spanned her new shape. In its wake, her fur smoothed out, turning from fibres into fabric, from matte into satin. The feeling of limbs and muscles was replaced with a uniform surface that she was acutely aware of, her body now an entirely new shape.

Celestia hummed with pleasure, admiring the elegant garment she had just woven from her accomplice. Just a pair of green underwear now, with a pretty lace edge and Withania’s nightshade cutiemark on the inside.

“Let’s see if the size is right,” she said, levitating panty-Withania behind her. “You’ll need to stretch a little, but if my estimate is correct, no one will even notice you.”

Through whatever magical means Celestia had imparted onto her, Withania’s senses still functioned, and she saw the now familiar view of her princess’ curvaceous behind. One powerful hind leg lifted, then the other in turn, threading through the fabric loops that used to be Withania’s legs, and she was lifted up. As she reached Celestia’s thighs, Withania could no longer reach all the way around, but Celestia did not stop, and Withania felt herself stretching, her body distorting and lengthening in ways she had never felt. And on top of that, more and more of her brushed up against Celestia’s flawless coat and supple hips, a degree of skin-contact impossible by any other means. Finally, her vision filled with the immense circumference of Celestia’s rear, her body and face made contact and was drawn up tight to conform with the royal ass.

As she had intended, Celestia noted that her new underwear dug in just enough pinch into her soft pudge, mostly hiding everything from sight. If she stood and raised her tail, Withania would be clearly visible - looking as if she had been painted in place, such was the tight fit - but with that shimmering cloud of tail lowered, no one would be any the wiser. Celestia realigned with her throne and sat down.

Settled in her seat she resumed her regal look, but the slightest curl of her mouth betrayed her secret pleasure. Knowing that the guards would not return until her request, she summoned the folder of her most loyal subjects. She flicked it open, seeing the pink “page” quivering excitedly. “Ah, quite an amusing opening chapter, this one,” said Celestia, poking the furry texture. The blue eyes stared back at her, happy to see somepony at least. Her mouth had been pressed flat so much that she couldn’t even speak anymore. Celestia gave her one last curious poke, marvelling at the almost spongy quality, before turning the page. “Applejack, I’m sure even you can appreciate a vacation now and then, especially with your friends. It’s very pleasing to see you relax.” The orange page seemed less animated than the first chapter, but Celestia’s hoof could feel the page getting warmer as she spoke. The emerald eyes looked left and right as the orange fur was tinted pink. Chuckling, Celestia flicked the second chapter over, letting it fall on top of the previous page.

“Rarity, you’re looking wonderful as usual,” said the princess, as Rarity looked up with a timid look in her eyes. “And a break would suit you, too. Yes, I think a week or two like this with your friends will do so much to get you all on speaking terms again. You’ll have a lot to talk about… once I let you speak.” The white page was turned, and Celestia found herself taken aback at what she saw. The fourth page was yellow, and looking up at her something approaching excitement. “My, are you enjoying yourself?” asked the alicorn. There was a little note of blushing there, but the page wiggled in affirmation. “I see… I think I will be re-reading this chapter later.”

The next page made Celestia chuckle. “Hah, oh Rainbow Dash, don’t look so cross!” she said, as the red eyes glared up, her flat face still managing to convey a pout. “You’ll find this a valuable learning experience in time. Even if that lesson was not to underestimate earth ponies.” Celesta shifted in her seat, slowly and deliberate, and smiling to herself in a way Rainbow wouldn’t fully understand. “I’m sure you’ll be enjoying this more later. Perhaps a private study session with me. Oh, speaking of studying…”

The blue page was shaking slightly, and Celestia could see why, as the page underneath vibrated with excitement. Celestia turned to the final chapter of her new favourite book. “Ah, Twilight, there you are. How could you have let you and your friends drift apart so suddenly? You had me worried.” This gentle admonishment quelled the shaking a little, but Celestia was quick to reassure the purple page. “Well, don’t fear; I’m going to make sure that all of you are bound back together in ways more than simply literally, aha.” She brought the page up until her muzzle was practically brushing against Twilight’s compressed face. “So get comfy now…”

Withania felt the entirety of that weight she’d previously felt once again, except this time she was flat and malleable, settled between the gap of Celestia’s buttocks, as well as pinned against the modest cushion of the throne. Unable to move or make so much as a squeak, she sighed to herself. She was finally able to relax, without a care in the world. For how long, she didn’t know. And that was almost the best part.
