A Long-Overdue Change of Leadership

Chrysalis awoke, stretching her arms as she sat up from the bed of what used to be Princess Celestia's private chambers. Not that anyone might notice it, of course; Chrysalis bore the spitting image of her predecessor, just in case she needed to be awoken for some crisis or another. The few who knew her secret remained entirely under her control; and one even visited her this morning.

"Good morning, 'sister'," Luna said, smirking as she closed the door behind her, as Chrysalis waited for Luna to lock the door behind her before she flashed her disguise away. "I hope you had a good evening."

"Quite good," Chrysalis agreed, gesturing for Luna to approach her. Chrysalis sat on the edge of her bed, her gorgeous dark body giving a diffused shine in the light as Luna sat beside her, and shared a kiss. Chrysalis slipped her forked tongue into Luna's mouth, holding Luna's cheek with her hand, as Luna affectionately kissed her changeling lover in return. Once the kiss broke, Luna smiled at her, and gave Chrysalis a kiss on the nose.

"How is my dear sister doing in her new position?"

"As well as she could ever hope to be," Chrysalis said as she reached up and snapped her fingers, her magic flashing from her horn as, in the corner of the room, a chest of drawers with a "Do Not Touch" sign hanging from its front, shimmered away to reveal a very large cage, just the size for a tall and busty alicorn like Celestia to stand on her hands and knees, as well as plenty of cushions and pillows for her to curl up and sleep. Celestia's eyes opened, showing their now-permanent green glowing irises, replacing the magenta she once used to gaze upon everything around her. Her face lit up, in an expression reminiscent of a loyal dog eager for attention from its master.

"Good morning, Mistress!" she said excitedly, "Oh, and hello sister!"

"Hello, slut," Luna teased, "How do you like your new role?"

"It's wonderful," Celestia replied, "running the country was such a chore, but as Mistress' pet, everything is so easy! Life has never been better, and it's all thanks to Mistress Chrysalis!"

"And your Mistress thanks you for being such a good pet these last few months," Chrysalis chimed in, as she spread her legs, allowing her green cock to grow out from her sheath. A flash of magic, and Celestia's cage lock clicked, allowing the door to swing open. Celestia crawled out of it and dutifully crawled on her hands and knees across the floor. Chrysalis gazed in awe at the sexy sight of someone who once thought of herself as so high and mighty, so above everyone else, now eagerly crawling on her hands and knees to kneel before Chrysalis, and dutifully begin licking her balls.

Chrysalis looked to Luna and saw her doing much the same, spreading her legs to show her smaller, but still very impressive dark blue, almost black member to her sister. A product of the genital-swap potions Luna became fond of using when her sister was involved. Chrysalis grabbed Celestia by the horn, feeling and seeing the chitin-black magic nullification ring still fixed firmly to the bony appendage, and mashed Celestia's face unceremoniously into her crotch, forcing her nose in the space where the changeling queen's smooth sack met her shaft. She felt Celestia inhaling deeply as she manhandled the now impotent monarch for her pleasure.

"Such a good whore," Chrysalis moaned, "Fuck that's good. Use that tongue, just like that," she said, looking over to Luna, who stroked her own cock. "I see you've taken that potion again; Would you like to have fun with her, too?"

"Absolutely, my Queen," Luna replied, grinning as she got down off the bed, and knelt behind her sister, giving Celestia a firm spank to her rear. Chrysalis watched that fat thing jiggle from the force of it, and a light hand print start to form over one of the suns emblazoned on each cheek, "she's become such a whore, just like she deserves!"

"That she does, my Princess," Chrysalis agreed as she felt Celestia's muffled words of agreement through her sack, "Perhaps we should remind her just how much of a useless whore she was on the throne?" she suggested as she pulled harder on Celestia's horn, mashing her face into her balls more firmly.

"Oh of course," Luna said as she swatted the other ass cheek, making it jiggle as well, "How about in just three months, we improved Equestria's long-distance communication drastically, something that you couldn't get done in fifty years?" she taunted, accentuating those last two words with a spank to one cheek, then the other.

"Oooh, you know what else she couldn't get done?" Chrysalis added, as she pulled Celestia's head away from her crotch, looking the defeated monarch in her green-glazed eyes, "She couldn't create a counter-intelligence program that's worth a damn," she chuckled, as she slapped her new slave across the cheek, "Don't worry though, it's much better, now, but staffed entirely by changelings!" she concluded with a chuckle.

Chrysalis forced Celestia's face onto her cock, forcing it deep into her throat. The long-broken princess took it with ease, as Chrysalis felt that throat massaging every inch of her cock as it stayed there, her hand still on Celestia's horn and gripping it hard. She looked at Luna, who took Chrysalis' cue and shoved her cock into Celestia's rear, letting out a lavish moan of pleasure at her sister's accommodating rear.

"By the stars!" Luna exclaimed, "She's so loose! Have you really ruined her so much in three months?"

"She's laid a clutch of eggs in that time, too," Chrysalis lavished, using Celestia's head and throat like a toy, "It is only natural for a pony's body to become more accustomed to such penetrations."

Luna, meanwhile, continued pounding her sister's rear with reckless abandon, her eyes squeezed shut, her hands gripping hard on her sister's plush rear, squishing that soft flesh in between her fingers as she grit her teeth, baring them as the sounds of clapping of flesh against flesh filled the room.

"You whore," Luna grunted as Chrysalis watched, bobbing Celestia's head thoughtlessly on her cock as she watched Luna grow so passionate about railing her sister. "You useless harlot! NNGHHH!" she cried out, as she slammed herself fully inside of her sister's rear, holding herself still. Chrysalis watched with a grin, practically feeling herself what happened with Luna, as she soon after followed suit. Her own cock erupted in seed down Celestia's throat, right into her belly. She remained more composed than Luna as she came, though the pleasure still flushed through her body as her orgasm came and went, both her hands gripping on Celestia's horn firmly as Celestia swallowed every drop.

Soon, Chrysalis pulled Celestia off of her shaft, letting her now flaccid, green member flop down between her legs as Celestia coughed and gasped for breath. Chrysalis let go of Celestia's horn and watched Luna finally let go of her sister's rear. Chrysalis heard the wet sound of a cock slipping out of Celestia's rear, and smiled as she patted Celestia's head affectionately.

"Good girl," Chrysalis said, as Celestia finished coughing, and looked up at her Mistress with a loving smile.

Luna spanked her sister once more, contorting Celestia's smiling face into one of lust, as she looked back, blushing at the sight of her sister back there.

"Now clean yourself up, slut," Chrysalis said, gesturing to the bathroom, "Luna and I will leave soon, so make sure the door is locked when we leave. Do you remember our rule about visitors?"

"When you're not here, Celestia isn't here, either!" she replied rather upbeat, staring lovingly at Chrysalis with her green, heart-shaped irises, before she crawled on her hands and knees towards the bathroom, and closed the door behind her. The sounds of the water running indicated that Celestia did as instructed, and with a snap of her fingers, Chrysalis instantly cleaned herself off, followed by Luna, while her magic-induced male genitalia disappeared as Luna magically dispelled the effects of the potion.

"Should we check in on Equestria?" Chrysalis suggested, "It has been too long since we have toured this country, to see how well it is doing under our new rule."

"I believe it should be," Luna agreed, "and perhaps we can begin dealing with one lingering issue while we are in Ponyville."

"What lingering issue?" Chrysalis asked, standing up and fetching some clothes with magic, but looking at Luna quizzically.

"The Elements of Harmony," Luna explained, "Celestia's protege and her five airhead friends hold the only key to freeing Celestia. With the power of the Elements that they control, that magic suppression ring and that mind-control spell you have on her will break in an instant!"

Chrysalis paused, her face showing concern, but not despair.

"I hope you have a plan for it," Chrysalis replied, "They may not realize all the good they will undo if they were to act on such an idea."

"Thankfully for us, that would require those harlots to have the wherewithal to know that you are not actually Celestia in the first place," Luna said, "but it would be best for us to ensure that such a possibility never comes to pass."

"Indeed. Shall I prepare for bringing those six into a similar position to Her Royal Highness in there?" Chrysalis wondered, gesturing to the in-use bathroom.

"It would work most expediently," Luna agreed, "Their leader, Twilight Sparkle, I suspect has had a crush on Celestia for a long time, so seduction may be your best option."

A grin grew on Chrysalis' face as she dressed herself in Celestia's clothes, and flashed her green magic to turn herself into the exact image of the subjugated princess.

"Then let us set an impromptu royal trip to Ponyville!" Chrysalis said in Celestia's voice, as she caressed Luna's cheek.

Luna leaned in, raising herself up onto her toes to kiss Chrysalis on the lips.

"May your reign be unending, my Queen."

The pair waited for the real Celestia to finish her shower, and once she exited the room, this time on two legs, she went to the bed and sat on it in a position reminiscent of a dog. Luna and Chrysalis both pet her on the head, gazing into those heart-shaped green irises, confident that even in their absence, Celestia could not betray them.

"Make yourself comfortable," Chrysalis commanded her, "after you ensure the door is locked behind us, of course."

Celestia nodded eagerly, as she waited at the bed, while Chrysalis and Luna exited the room in their standard daily wear; upscale, but not so much so that it could be damaged by dirt and grime from going out and about Equestria.

Chrysalis locked the door behind her, and nodded at the guard just outside the door, as she waited for the sound of Celestia on the inside fiddling with the lock to ensure it stayed that way, before she patted the guard on the shoulder. The guard, whom she knew to be a disguised changeling, smiled back to her, flashing his green eyes briefly and lovingly towards his mother before he returned to attention.

Luna cast a small spell, allowing them to speak telepathically, so as to not arouse notice from the content of their conversation.

"How do you know which ones are yours?" she asked.

"All changelings can recognize their own, disguise or no," Chrysalis explained, as she lead the way through the castle, now a far more bustling epicenter of Equestria than it ever was under the real Celestia, "It is difficult to explain to one who does not share our senses, but they all emit an aura about them, one that we simply sense, if you will. It ensures none of us attempt to feed on each other, as it is quite an unpleasant sensation for both parties involved."

As the two walked, guards, secretaries, administrators, bureaucrats, many of them disguised changelings, hustled to and fro with boxes in their hands and arms.

"This whole profession of couriers throughout the castle alone is far more efficient than even the magic we used previously," Luna noted, telepathically.

"It is borne of how it works in my hive," Chrysalis explained, "messengers are always on the move, communicating with one sector's captain to another. In my hive, anyone can be a courier, but making it a profession here allows them to know the castle layout so well that even those who cannot cast spells, such as earth ponies and pegasai, can efficiently send and receive packages."

"An intra-castle parcel service," Luna noted, "But simple messages remain confined to magic."

"Indeed," Chrysalis agreed, "That crystal Celestia used to overlook and did nothing with shall serve as the model for how a communication network across all Equestria will operate, and since my drones are finishing a second one, perhaps we can have Ponyville be the first expansion of the network to outside of Canterlot?"

"As good a reason as any to visit that place," Luna agreed, "And a good way to get that purple ditz to have some private time with you."

"Of course, but also, this communication network will be for the good of all of Equestria, not that any of the airheads in charge ever saw it. I never believed I might be saying this, but I look forward to Equestria's prosperity, even if it needs a little culling of their leadership to get there."

"A culling, I like that," Luna said, smirking, "then let us get to Ponyville, my love, and ensure your rule continues."

The two exited the castle, where a small but elegant dirigible airship waited for them. Boarding to the salutes of various guards and ground crew, half of whom were disguised changelings, the pair descended into the royal cabin to get comfortable as the ship made a quick departure. Hardly a ceremony here, but Chrysalis expected a royal reception when she arrived. As the ship departed from the castle's private airship dock, Chrysalis sent a magical message to her drones to get the first of the communication crystals sent to Ponyville immediately, and she and Luna sat down on a couch, facing a forward-looking window, watching their progress towards the sleepy town of Ponyville.

. . .

After an hour of flight, the airship closed in on the small dock Ponyville had to offer. Easily within sight of the gaudy castle in which Twilight Sparkle lived, and the stately Mayoral Plaza at the center of town, Chrysalis gave Luna a hug as they descended down, watching the earth pony dock workers signaling the airship in for a safe landing.

"You know what else we can do here?" Chrysalis noted as she observed the surprisingly slow train pull into a nearby station, "improve the rail network. How long has that train system been in place?"

"About a hundred years," Luna said, "it was the pride of Celestia's reign back then, but I doubt she had a true hand in any of it."

"And in a hundred years, is this still the best our capabilities can offer?"

"Unlikely."

Chrysalis thought a moment as they felt the slight jostle of an expert landing onto the platform. A flash of green from her horn later, and she stood and squeezed Luna's hand.

"Let that be our next project after we upgrade the communication network."

"Agreed, and it would be very useful for the rail network with that already in place."

"Truly?"

"Yes, a fast and widespread communication network can manage a large number of trains, which should make getting around Equestria far more efficient than our current method of airships and slower trains."

"Then let us make the communication our priority, starting with the existing train stations. We will need a list of the biggest train hubs in Equestria by the time we get back."

"Once the crystal in Ponyville is installed, I'll send such a message to the engineers while you work your way into Twilight's trust," Luna said, giving Chrysalis a teasing squeeze on her rump.

Chrysalis chuckled and gave Luna a firm spank to the rear right before the door opened to the outside, leaving Luna blushing and holding in her reaction as various dock workers bowed to the two princesses. Chrysalis, disguised still as Celestia, waved to them all and gently stepped out onto the platform. The workers looked up expectantly at "Celestia" as if they expected something, but Chrysalis showed no indication of any expectations as she and Luna proceeded off the platform, followed by a small retinue of disguised-changeling guards.

"Why are they staring at us?" Chrysalis asked.

"My sister normally has a whole song and dance when she goes anywhere," Luna explained, telepathically, "I swear she got off to seeing ponies grovel before her in all the pomp and circumstance she would have. They're expecting you to command them to do something."

"Should I?"

"I am not asking you to be as ostentatious as my sister, but it might be best to not arouse suspicion."

Chrysalis cleared her throat and looked at the dock workers.

"Please fetch Princess Twilight and the Mayor," she declared.

The workers nodded and rushed off into town, as Chrysalis looked to the sky and saw a transport dirigible descending into the center of town, near the pavilion. It already drew quite a crowd, and Luna soon gestured to Chrysalis to approach.

A gingerly stroll later, and the workers from the transport dirigible, all disguised changelings, unloaded the large crystal, and Chrysalis ensured that it was placed properly inside the pavilion, with support structures and a connection to the latent magic in the air of Equestria, allowing it to power on just in time for Twilight Sparkle and the Mayor of Ponyville to arrive.

"Your Majesty, you grace us with your presence!" said the mayor, who gazed upon this incredible device as the workers finished installing it in the center. The crystal towered over ponies at ten feet, as it hummed and glowed with blue magic. It was smaller than the one in Canterlot, but Chrysalis' workers informed her that it possessed sufficient power for a town of Ponyville's size.

Chrysalis turned to face the Mayor, who beamed with excitement, and saw Twilight, dressed in a formal dress, but bearing an expression of awe but a lack of understanding. Chrysalis internally wondered if Twilight even read the missives her superior sent to the leaders around Equestria. Still, Chrysalis smiled warmly and nodded at the mayor.

"With your town's proximity to Canterlot, I determined that Ponyville would be the optimal place for the first step in expanding the new Equestria-wide crystal communication network," she explained, looking from the Mayor, to Twilight, to the others around them, "and I promise you that one day very soon, instantaneous communication from anywhere in Equestria, to anywhere in Equestria, will become a reality!" she declared.

"What about the post office?" cried out another pony, a stallion in the back row, flanked by a grey pegasus who bore an equally concerned, if wall-eyed expression, "Are we gonna lose our jobs?"

"But of course, do not worry about the Equestrian Postal Service, for this network can only send simple messages. Hand-written letters, postcards, and parcels, shall not be supplanted by this network," Chrysalis explained in the calm, and judging by the reactions of the ponies around her, more calm and serene than previous assertions by the princess, "only those with the most urgent matters should use this network. Currently, only the Mayor, Princess Twilight, and those designated by their authority, can use this network from here, but soon every pony will be able to enjoy the magic of instantaneous communication from here in Ponyville, to as far away as Somnambula!"

Applause sounded, as Chrysalis looked to Twilight once more, and gave her a little wink. Twilight caught it, and a grin formed on her face, and winked back. Internally, as Chrysalis raised her arms to accept the applause, she wondered what things Celestia and Twilight got up to before Celestia's secret dethroning. She felt quite eager to find out what a layabout princess got up to with an airhead mare like Twilight.

As the applause died down, she looked over to Luna.

"I could not have done any of this without the help of the greatest expert in signals, codes, and magical algorithms in all the land, my lovely sister, Princess Luna, and of course, the many engineers who worked tirelessly these past few months to get all of this done," she said, gesturing to Luna, to another round of applause, who took a bow, and gestured to the many disguised changeling workers around her, who also took a bow.

Soon the applause died down, and ponies dispersed as Chrysalis and Luna approached the Mayor and Twilight. The Mayor immediately shook both their hands, and Twilight bowed to the two princesses in turn.

"Thank you very much, it's such a surprise to see you here!" the Mayor said, "I could have prepared your usual ceremony and parade if-"

"Worry not," Chrysalis said, cutting off the Mayor, "I believe we have more important things to dedicate our resources towards than pomp and circumstance for such a brief visit," she assured her, "I shall be gone tomorrow, but do let my secretary know when an official state visit can happen, and we can put out all the bells and whistles. Oh, here, let me attune you two to the crystal," she said, leading them up towards the giant crystal. She placed her hand upon the large blue crystal, and gestured for the Mayor and Twilight to do the same.

Once they did, a small spark emanated from their hands, and Chrysalis smiled.

"There, now you can attune yourself to the crystal and speak a message that you wish to be sent to anyone in Canterlot. It will appear as a magically-written paper in its appropriate room, so as to not overwhelm the receiver at inopportune times."

The two nodded, as Chrysalis turned her attention to Twilight.

"Mayor, you may go, I have a private matter to attend to with the Princess," she said as she looked to Luna, "Would you like to come along, sister?"

"Oh it is quite all right," Luna replied, "I shall see to the refueling for our return home." Then, telepathically, Luna added, "Take your time."

Chrysalis nodded and looked to Twilight, who looked back at her, giving a sort of anticipatory look of coyness. A wink from "Celestia" put a knowing look upon Twilight's face.

"How about you come to my place?" Twilight suggested.

"I would love to, my faithful student."
