How many years had it been? Five hundred? Six hundred? More? So many years since that meeting that had defined Celestia’s life. Ever since that day, it was as if a dark fire had been lit within her heart, pushing her lustful wickedness to greater and greater heights, and burning away any morals that she might have had.

At first, Celestia had to be careful and cautious. Luna after all, whilst still a slut like all alicorns, did not share her sister’s lack of morals. So those days had been spent building her own reputation, earning herself a name as the kindest, most benevolent ruler in all the world. Not one of them seemed any the wiser to the true perverse nature of their Princess.

Well, all but her sister. While Luna never quite caught on to her new true desires now, she did sense something different in her older sister’s nature. And Celestia probably didn’t help matters by secretly lusting over her sister’s body. With her inhibitions removed she could now truly appreciate her sister’s lovely dark body, her huge tits, and an even bigger ass. Every day had been a struggle not to sate her lust upon her sister. It had almost been a relief when she had banished her to the moon.

With her sister gone, Celestia had been free to experiment. She had no taste for stallions, none could compete with her Master to come. To start with she had been simple, picking out a sexy, open lesbian and having her way with her behind closed doors. Later she started to experiment with more dominant techniques. Ass sitting, chains, and collars, trapping them between her thighs and strap-ons were her first experiments. At first, she narrowed her focus to lesbian subs, then all lesbians, then the straight mares. Soon, Celestia found that behind closed doors there wasn’t a single mare that she couldn’t make her personal drooling slut.

She’d even made a small army of them that operated under the name L.U.S.T (Legion of Undercover SluTs) that served her every whim. Whether it was in the bedroom, in her sex dungeon or simply serving as spies for their Princess’s perverted plans. They were the only ones Celestia trusted with a hint of her plans and had become such massive army of whores and every one of them were almost fanatical in making Celestia’s dream come true.

But that was just behind closed doors, in public she presented herself as the most diligent and benevolent ruler the world had ever seen. And much of this was true. She had overseen a multi-century golden age for her country, passing progressive laws, developing her country, and keeping threats in check. But there was a darker reason behind her actions, after all, a better Equestria would be a much better prize for her future Master.

So within her laws were loopholes that she could exploit for both her Master and her own sexual gratification. When she built her cities she strategically designed them so that red-light districts formed for a more vibrant sex life. She patronised the dresses that showed a shade more skin and criticized any outfit that was concealing, a death sentence for any trend. Piece by piece the fashion for mares in Equestria shifted to a paradise of exposed flesh and skimpy outfits.

And every day, she got closer to the day when she might hope to finally lift the veil. The day when her Master would be ready for her, for her to have the chance to throw her crown at his feet and wrap her huge tits around his cock. She could only imagine the looks on her subjects' faces when they saw their ‘perfect princess’ throw herself upon her Master’s cock.

Today however, she had another task. As the prophets before had told her, there would be a number of milestones she must keep intact in order to ensure her desired future came to pass. And another was now approaching, the ascension of a new alicorn to one day rule over the Crystal Empire. One who would wield the element of love…among others.

Surprisingly though Celestia didn’t have to choose any particular pony to take such a position, she was free to choose any pony. It was an opportunity that Celestia seized with both hands, so she sent out her L.U.S.T agents across Equestria to find the perfect template. This template would have to be a slut with a natural affinity, one that would only be amplified under Celestia’s tutelage.

“Your Majesty,” a Royal Guard announced. A sexy young mare, a result of Celestia’s secret, a centuries-long program to slowly weed the guard out of all but the sexiest guard mares. Eventually, ponies just saw it as a normal tradition, one that even the most prudish traditionalist defended with an unreasonable passion. “Ms Cadence has arrived.”

Her stomach bubbled with feelings of glee at the news, her wings flared out with excitement, and a bright smile broke across her face. “Send her in dear, then leave me alone with her.”

The guard bowed and left, and shortly after a pink-furred Pegasus entered the throne room. Celestia had learned a lot about this particular Pegasus, she was intelligent, confident, and beautiful. But far more importantly to Celestia, she was a massive slut.

For now, though Cadence seemed confused as to why she had been summoned to the Princess’s hall. She showed little of her normal confidence today, however, awed as she was by the busty Solar Monarch.

“Ms Cadance,” Celestia purred, her fingers drumming against her throne, distracting her from her urge to stick them into the Pegasus’s slit and force her to cry out Celestia’s name. “I’ve heard so much about you.”

“You have?” Cadence asked, a hand covering her mouth in surprise. As she did so, Celestia took the time to examine her subject. She was certainly a beautiful Pegasus, she had a lovely hourglass form, a sizeable ass and tits, and a lovely mane of hair. A promising start, but Celestia wanted to see how she would look enhanced by an alicorn’s slutty body.

“All about you. I’ve been waiting to find such a talented mare like yourself for some time, please follow me.” Celestia rose from her throne and Cadence into her bedroom. She pulled a specific book on her bookshelf and grinned at Cadence as she led her inside.

“A secret passage?” Cadence asked confused, there was a nervous awe in her voice. She clearly didn’t know why she was here, and Celestia looked forward to informing her. “Where does it lead?”

“All in good time, my dear, but for now I want to talk about you. I know you’re a particularly intelligent mare, confident and popular as well. I’ve heard you are well respected by your village.” Celestia explained as they walked, but then her smile became sly. “But what really fascinated me was what you got up to behind closed doors.”

Cadence stopped on her heels, a look of pure dread appearing on her face. "Oh, then what have you heard?"

“I’ve heard of a lovely little minx who fucked her way through several villages and towns. A mare who could barely manage to go an hour without getting her pussy eaten, or eat another out, or fucking another mare with a strap-on.” Celestia explained, enjoying the way her face scrunched in fear. “But that’s the most modest of what I’ve heard. How many women was it that you invited to the summer solstice orgy? I couldn’t find out if there are more than fifty or not.”

“Eh, heh you heard about that. Well before you judge me you should know-“

“Oh, I wasn’t judging. Quite the opposite actually, but there was one question I had to ask,” Celestia resumed walking along the tunnel, Cadence following behind her. “My agents suggest that you’ve never taken a dick, but they insist you’re not a lesbian.”

“Well…that’s-“ Cadence stammered, still shocked that she was talking to the Princess about such candid affairs. It wasn’t an uncommon situation for Solar Monarch.

“No need to hide anything from me, dear. Tell me the honest truth, I’m not here to judge you, if anything I’m quite impressed,” Celestia said with a reassuring smile. “And I think I can relate to your issue.”

Cadence looked intrigued, yet a little bit scared to have the Goddess of Equestria so intrigued by her sex life. “It’s nothing really complicated about it. I do really want a good dick but there’s never been one good enough for me. All the dicks I’ve seen have been weak and pathetic and would never have even made me cum.”

“And sexy mares do make you cum, but if I’m correct they don’t satisfy you, correct? According to my spies ever since your eighteenth birthday, you’ve been as horny as a rabbit desperate for a real dick. I think I might have a solution,” Celestia said with a small sly smile.

“You do?” Cadence asked, cocking her head sceptically.

Celestia had reached the end of the tunnel and pressed her hand against the door. She shot an inviting smile to the desperate slut. “Behind this door is the greatest secret in Equestria’s history, if you come inside I assure you you’ll never be unsatisfied again."

Cadence peeked at the door over her shoulder. "Greatest secret in Equestria?” She became intrigued. “I’m in.”

“Then after you,” Celestia said opening the door and gesturing to enter. Inside was a room without any windows, with a scarlet carpet and pitch-black walls. On each wall was a picture of the prophets from Celestia’s memory. Her student, her Master, her Mistress, and the Time Princess. All had yet to come, but Celestia was sure they’d enjoy this dungeon when they found it.

But that wasn’t what captured Cadence’s attention. She was enraptured by the shelves of dildos, strap-ons, and other sex toys, or perhaps she was distracted by the sex machines in the room. Perhaps it was the statue of Celestia's Master in the centre, or accurately his dick. Whilst the images of the prophets were only as accurate as her memory, there was no imperfection in the shape of the statue's dick, the image seared perfectly in Celestia's mind.

"What-what is this place?" Cadence stammered looking around in a daze. There was a mix in her emotions, her mouth hung open in shock, eyes darted around in surprise. But her nipples grew ever harder under her dress, her pussy started to drip across the floor and there was a quiver of hope in her voice.

Celestia smirked as Cadence's world came crashing down around her, and knew that some part of Cadence was eagerly watching the new world being hinted at. Behind her, Celestia let the spell she had been secretly casting on herself fade away, it was a spell that made it appear that she was wearing a regal (albeit quite revealing dress), and as it faded away her true outfit was revealed. A black latex corset, several times too small, struggled to contain the Princess's mountains of tits whilst only a thin strip of latex between her cheeks and a pair of fishnet stockings. All topped off by a pair of black latex gloves and boots, the latter of which clicked against the floor whenever she walked.

“This, my dear little Cadence is the truth.” Celestia purred stepping into the room behind her, the door slamming shut.

“The truth?” Cadence said, turning around and seeing the outfit Celestia was wearing. The Solar Monarch was pleased to see the Pegasus’s mouth dry up at seeing her.

Celestia lifted the tip of Cadence’s chin, her seductive dominant eyes pouring into the Pegasus. “The truth, my darling little Cadence is that Equestria is founded on a lie. This is the true Equestria.”

“True Equestria?” Cadence whimpered, looking around in awe at the room, eventually, her eyes falling on the statue of their Master Spike, or more specifically his dick. She raised a quivering hand at it, words failing to form, perhaps this could sense that this was cock she had been waiting for.

"He is the true ruler of Equestria, my kingdom exists to prepare the world for his rule. To serve his every need as his slaves,” Celestia purred, before casting another spell. A golden imitation of her Master’s dick made of light appeared on her body like a strap-on. “And in exchange, he will use us as his sex slaves. Allow me to demonstrate.”

Without foreplay or warning, Celestia tore Cadence’s dress apart and thrust the light cock into Cadence's body.

“AHHHHHH! WHAT-WHAT ARE YOU DOING?! OH FUCK!” She screamed as Celestia rammed into her. She felt no need to be gentle, from what she had heard, that wasn't something either of them wanted. "OH SWEET CELESTIA! ITS SO GOOD!"

“I know,” Celestia whimpered, leaning forward so that her canyon of cleavage pressed against Cadence’s back, to give herself better leverage. “But this is just a taste of what’s to come.”

“A taste?” Cadence gasped in shocked disbelief. Sweat was now drenching her face, which had turned a deep red in lust.

“Well, it all started just a few years after the creation of Equestria…” Celestia explained with an almost sing-song patronizing tone. She continued to explain the true purpose behind Equestria’s existence, herself, and why Cadence was here. All the while pounding Cadence with her magical dildo. There was an animalistic desperation in her eyes, one that only grew more intense. Celestia already knew this was by far the best sex the Pegasus had ever received.

"So, is this what you want, Cadence? Will you help me make this land into a perverted paradise? Guide the Crystal Empire in Equestria’s footsteps, in our Master’s name? Shed off the mortal coil and become an alicorn? Not a noble goddess as you’ve been led to believe but a creature of lust, depravity, and sex?”

“Yes, Celestia! Please do it! I want it! I want to be fucked by our Master! Make me an alicorn! A Princess of Lust! A slave to our Master! Do it, Celestia!”

“Then cum, my slut. Cum and begin your new life as the Slutprincess of Lust!" Celestia screamed, making sure to ram particularly deeply into her.

"OHH FUUUCCCK!" She screamed as she came to the imitation of her Master's cock. Then, she was engulfed in a divine pink light and the transformation into an alicorn slut began. Her mane flared outward, extending from her neck all the way to her ass. Her waist pinched as her hips ballooned outward, to accommodate her new bubble ass, whilst her tits ballooned outward to the natural size of an alicorn.

"Fuck!" Cadence gasped as she finished her orgasm and crumpled into a heap on the floor. Her hands started to explore her new alicorn body, especially her new ass, tits and pussy. "I'm so beautiful, so powerful, and I'm even hornier than usual. Are you always like this?"

"I'd say you get used to it, but that would be a lie. At least until our Master Spike comes, so make sure you follow my plan, my naughty little Princess of Lust and it'll be all alright," Celestia soothed Cadence in a stern yet motherly voice. "Although being open about being the Princess of Lust would raise too much suspicion. Perhaps you might assume a public identity as the Princess of Love, the two do overlap after all."

"Does that mean your role as Princess of the Sun is just a public identity for you?" Cadence asked, cocking her head curiously. Celestia had powers only over the sun after all, yet would it not be appropriate? Perhaps something she could research applying, or requesting her Master for help when he arrived. But perhaps such a title would be fit in spirit if not practice.

"Publicly, my dear Cadence, I'm the Princess of the Sun, but in private and truth, I'm the Slutprincess of Servitude. Of sex slaves, submission and devotion to our Master."

Many more years passed since Cadence's ascension and Celestia's declaration as the new Slutprincess of Servitude. With Cadence's help, Equestria prospered, perhaps even more so than the time the prophets came from. Hindsight was an immense advantage after all, and Cadence proved an adept accomplice. Celestia told her all about her role in regard to Ponyville and their Master Spike, and she was eager to help. She soon became a temporary leader of L.U.S.T. and proved surprisingly adept at it.

But now Celestia was dealing with a separate issue, another fixed point was coming up. This time it was the betrayal of Sunset Shimmer, and her defection into the human world was inevitable, necessary in fact. And it did not take long for Celestia to see why. Already it seemed that the pony despised her.

“There you go Sunset,” Celestia said, placing down a plate of pancakes on the table. But, as predicted, Sunset ignored them and just picked up a granola bar. “You know I do put a lot of work into this breakfast.”

“Too busy,” Sunset scoffed, mouth full of the granola bar, her nose stuck deep in a book. As Celestia expected the book was a topic about alicorns, which Sunset had been reading in spite of Celestia’s warnings. That wasn’t the only warning Sunset ignored, in fact, Celestia believed Sunset was in that phase where she deliberately rebelled against any suggestion Celestia gave her.

Unfortunately for her, Celestia had been one step ahead of her for a while now.

“Sunset,” Celestia chided in the nagging tone she knew Sunset hated. “We talked about this, you must start wearing appropriate attire. What you’re wearing is just too scandalous.”

Celestia had to hold back a smile as Sunset scoffed, and Celestia just knew she was digging in her heels in spite. Already Sunset had adopted a perfectly whorish outfit. A loose leather jacket with nothing underneath, a small thong, and a lovely pair of fishnet stockings were all she wore. Once scandalous, this clothing would now be only mildly revealing.

“You such a prude Princess, this is what everypony wears.” Sunset said a noticeable bite in her tone.

“Well make sure you don’t wear any less, could you imagine just what it would do to my image if you did that?” Celestia asked, certain that the selfish motive she implied would only encourage Sunset more. “Speaking of my image, I’ve heard certain rumours about you. Spending time in strip clubs, having sex with whores, those had better not be true.”

“Or what?” Sunset demanded, sending Celestia a glare. For Celestia though she had made sure that every bluff she made in these regards was a threat she wouldn’t back up. To a rebel like Sunset, she might as well have been begging her to become a whore.

“Or there’ll be consequences.” Celestia said with a stern glare, just daring her to do exactly that. A challenge she was certain to meet, and slowly become the whore that Celestia was moulding her to be.

And several years after that day, the time came. Sunset abandoned Celestia to escape into the human world, with quite the dominant streak. Sunset believed that her new addiction to sex was her form of rebellion, but she was playing right into Celestia's designs.

The final tipping point had been Celestia's adoption of a second student, something Sunset's pride could not tolerate. Twilight was still a few years younger than Sunset, but much more different in personality. She did not rebel, in fact, she did quite the opposite. Thankfully this was a trait Celestia could use to advantage, with a little help.

“Babysitter?” Cadence asked, a little confused. They were Celestia’s secret sex dungeon, Celestia had her leg lifted straight up and had Cadence knelt before her as she ate the Solar Monarch's cunt. “Isn’t Twilight a bit old to need a babysitter? And why would you want me to do that?”

“Twilight is the kind of pony who looks up to her superiors. She’s such a dutiful pony, who looks to her loved ones for guidance and inspiration. I need you to be my new student’s lovely muse, and inspire her to follow a life of perversion and debauchery,” Celestia explained, wrapping her raised leg around Cadence’s neck and pulling her in. “I’m certain with enough time, she’ll become a perfect young mare who looks up to shameless sluts like you for inspiration. Think you can do that?”

“You can bet on it.” Cadence said with a smile.

“Good,” Celestia purred, stroking Cadence’s hair affectionately. “Make sure you also introduce yourself to Gleaming Shield as well and remember the spell I taught you.”

“Which one?”

“The one that will allow you to be impregnated by a mare, I’m certain you'll find a good use for it. And remember we must leave our Master alone, for now, let destiny play its part until the day when I send you to Ponyville. Understood?"

"I understand, Princess," Cadence purred, before resuming licking Celestia's pussy.

It was only a few years since that moment until the day arrived. Celestia had spent centuries practising, she had refined Equestria so it would be the perfect gift and made every effort to make it as powerful and as much of a pervert's paradise as possible, whilst enhancing her own sex appeal.

It was perfect, all ready to be handed to her Master on a silver platter.

Author's Note

That was a long chapter, but I hope everyone enjoyed it. A big thank you to everyone who helped

So an opportunity has opened up. I received a message from Brianna_green who offered to create a comic of a truthful dragon albeit at $100 a page. Unfortunately, I can’t afford that by myself so I’m opening up another crowdfunding ko-fi page. For every $100 milestone, I’ll commission another page, with a bit of luck we might actually get to the first sex scene. We’ll have to see.

I’ll want to keep it separate so people can donate to commissions if they still want to, but unfortunately, Ko-FI only allows one fundraising page per account. So when you donate leave a message saying if you want to donate to the comic or commission.
