"So, what year is it?" Spike asked, as the four of them exited the time portal. They stood on the mountain range that would one day become Canterlot back before Equestria had truly begun to populate. It was a misty spring day just after the winter, the Windigos must have started to disappear, and the blizzard they brought receded. The night was starting to recede, and Celestia should be raising the sun soon.

“It’s just a few years after the first Hearth's Warming, Master, the different pony races are still spreading throughout Equestria as they settle the lands. You can still see the town that will one day become Canterlot down there," Flurry Heart said pointing down at a town that was just slightly larger than Ponyville. Specifically the only stone structure in the town. “You’ll find Celestia in there. With Luna having business in another region, she’ll be alone.”

“Thank you, Flurry Heart, so let’s see what Celestia was like in her youth.” Spike said before striding forward only to be held back by Rarity.

“One moment Master.” She lit up her horn, bathing Flurry Heart, Twilight, and Spike, in light. When it receded the four no longer resembled a dragon or alicorns. Instead Twilight changed in appearance into a unicorn form, Flurry Heart became a Pegasus and Spike became an Earth Pony. “There we are.”

“Good idea, Mistress, now let’s go visit the Princess.” Twilight said, before leading their way through the rustic town. They passed through without drawing too much attention to themselves, with only the occasional pony paying them any mind. With a quick question, Spike was able to grant the four of them a special private audience with the Princess, and so, they were let in.

When they found Celestia they found her in the process of raising the sun. She was quite different than her older self. She held herself much more meekly than the regal, composed goddess of beauty from their day. This Celestia had the youthful energy of a cheerful teenager.

“Oh, hello you must be the private meeting I have scheduled. Just one moment,” Celestia chirped, sparing them a quick glance as she finished raising the sun, much more clumsily than she did today. “So, I’m afraid you’ll have to forgive me. I know I should be better organized but there’s just so much paperwork.”

She turned to the four of them and hopped on her throne. As she did so Spike noticed that her ethereal mane was still a simple pink, her body much less shapely and large.

“Do those tits never stop growing?” Spike under his breath, quiet enough that Celestia did not hear him .

“So, please excuse me but could you please remind me why you’re here?" Celestia asked almost demurely. She didn't quite have the same confidence as her future self.

“We’re here to talk to you, Celestia, about your responsibilities as a Princess, and what you could do with your power.” Rarity explained, lighting up her horn.

“You believe us, don't you?" Spike added, to make sure their questions wouldn’t be questioned. “Trust us too, right?”

“Of course I do, so this is some kind of test right? Are you going to be testing Luna as well?” She asked, with an innocent curiosity.

“No, I don’t think so. Now, why don’t you tell me everything you want to do with your position, darling? What plans are formulating in your head now that you rule Equestrian?” Rarity asked, the devilish smile of a succubus on her face, tempting this poor virtuous soul into a life of debauchery and sun.

The young Celestia tapped her chin in thought. “Well, I guess I want to make this the best kingdom possible for all my little ponies, a place where we can all be happy and under a kind and benevolent ruler.”

Rarity strode forward, each footstep echoing through the room, her lovely lavender smell filling the room. The young princess seemed to recoil under the weight of Rarity’s sheer presence, pushing herself back as the unicorn approached. Rarity cast a spell on the young Celestia, forcing her to answer honestly.

“Do you see my body, Princess? Do you see how beautiful it is? How perfect it is? Did you like mares before? I know you do now,” Rarity purred, striding to the throne as Celestia nodded dumbly. Rarity slammed her hands on the armchairs of the throne and pressed her face deep in Celestia's personal space. “Now tell me what you really want.”

The young Celestia squirmed as the spell compelled her dirty fantasy out of her throat. “It’s not exactly appropriate.”

“Oh, tell me more, darling.” Rarity said, squeezing her glorious ivory tits together and enjoying the way Celestia’s breath hitched in her throat.

“It’s wrong,” Celestia protested weakly, but her eyes were drawn to Rarity's breasts.

“All the better,” Rarity purred, “now tell me what you want.”

Celestia’s fingers twitched, but she was compelled to answer. “Ever since I was given leadership over Equestria, a certain dirty thought occurred to me.”

Rarity gracefully made her way behind the throne, Celestia’s eyes were fixed on the unicorn all the while. Rarity’s elegant hands started to massage the Princess’s shoulders. “Don’t be ashamed darling, just tell us the truth.”

“I imagined-“

“You wanted,” Rarity interrupted firmly. “And you still want it, don’t you? Don’t deny it.”

“I want to see how far I could push my power. I want to be loved by all my ponies, but all the while for them not to know the true me. I want them to adore me, completely ignorant of what I really am. What I’m really doing,” Celestia admitted, Rarity smiled as she washed the princess in another spell. This time one of Cadence’s temporary anti-inhibition spells, but under Rarity’s power she was able to make such an enchantment last eons until a time when such inhibitions would no longer matter.

“And what is it you’re really doing?” Rarity pressed, leaning forward and whispering into the Princess's ear. Her hands were working their way down Celestia’s body.

“Being a horny bitch,” Celestia exclaimed, the words escaping her mouth like water bursting from her mouth. “That I was to use them to sate my lurid lusts. That was I a perverted queen, twisting their souls for my perverted amusement. Making an Equestria where I would order my guards to summon a slut for me to fuck. I’d sneak provisions into the laws giving me new powers to delight in depravity. I’d slowly corrupt this nation into a nation of whores, and as Princess, it’d be right to use, abuse, and dominate them all.”

Celestia gasped, her face turning red with lust as she confessed to every one of her repressed sinful desires. But then her face screwed up, a shade of disappointment on her face. “But I can’t. That would be wrong.”

“So?” Rarity’s hands moved from Celestia’s shoulders and slipped under her dress. There, she took one breast in each palm and molested the small piles of tit flesh. The arousing sensation, amplified by Rarity’s magic, rippled through Celestia’s body, transforming the resistance in her body into pleasure, her morals started to escape her in weak moans of pleasure. “What does it matter if it’s wrong?”

Celestia let out a squeal as Rarity’s left hand moved from her tits to her pussy. Under Rarity’s inhuman skill, the young Celestia could never resist for long, and soon her body convulsed in her first, but hardly last orgasm.

"OH, OH, OH!" Celestia squealed, sweat soaking through her fur as she grew in lust.

“Just think of what would happen if you indulged yourself. You are exceptional, beautiful, sexy, with a perfect body. These little ponies need to serve you, to please you, to fuck you. You’re intelligent, Celestia, imagine if you used that intellect to warp and corrupt these ponies, sneaking in lovely perverted laws to allow you to fuck them. Slowly you’ll turn this land into a den of sin, so slowly that no pony will notice. A paradise for you to sate your lurid lusts,” Rarity chanted into Celestia’s mind. Spike couldn’t tell if she was using mind control, or simply funneling lust into her and using her words. “Maybe you could even do it to Luna? Would you like that? Fucking your sister in sexy, sinful depravity?”

"That-that would be amazing!" Celestia moaned, legs squirming. Spike himself was getting impatient, but he was still eager to see Rarity’s efforts bear fruit. His cock stirred, out of the corner of his eyes, he could see Twilight had stuffed her fingers into her pussy, whilst Flurry Heart had begun to molest her own breasts. Spike wondered if she hoped to have tits as big as the Solar Diarch's someday.

“You want it, don’t you, Celestia?” Rarity purred.

“I want it!” She moaned, eyes closed as she squirmed in ecstasy.

“You need it.”

“I need it!”

“You’ll do it.”

“I’ll do it all!” Celestia screamed, as her morals faded away completely under Rarity’s anti-inhibition spell.

“Excellent.” Rarity purred before planting a deep kiss on the alicorn's neck. This proved to be too much as the pink-haired alicorn let out a scream and came for the second time. Meanwhile, Spike could feel that he would be soon having his way with the Princess, and that was causing his dick to harden quite nicely.

“Now, darling,” Rarity purred. “We need to talk about how we’re going to make everything you desire come true. But only if you do as we say, only if you follow our plans. If you do that, then all you desire will not only come true, but be destiny.”

“Destiny?” Celestia moaned as Rarity glided over to the other three, leaving the needy Princess wanting. Rarity made a small flourish with her hands and the disguises of the four ponies disappeared. Celestia’s eyes rounded like saucers when she spotted two alicorns and a dragon.

The older Celestia may have responded more gracefully but this younger version was a little less sure of herself. So instead she gawked, eyes darting from each figure before her. “Bewaaa?”

“We’re from the future, Princess,” Flurry Heart spoke up. Eyes darting to her Master Spike for approval. “We’re prophets from the future, here to offer you a deal.”

“Prophets?” Celestia asked skeptically. “What kind of deal?”

“A deal where you get free reign to turn Equestrian into your lovely paradise of sin Princess,” Rarity said as walked back to Spike's side and started to cup Spike's crotch. "And access to the greatest dick in all of Equestria."

"What do you think, Princess? Irresistible, isn’t it?” Spike asked when Rarity released his cock from his pants and shot the princess a cocky smirk.

“Yes, yes… it looks divine,” Celestia muttered, rising from her throne. She was shy, but naked after Rarity’s efforts. It seemed she lacked the confidence to truly indulge in her fantasy, but her eyes were still smokey with lust. Her petite form and small breasts were no match for her future divine beauty but still charming in their own right.

“Your queen demands you service her.” She said, beckoning Spike over with a finger.

“Oh, I think you misunderstand Celestia. If you want to be the sex queen of your dreams it's only going to happen by being the sex slave to our Master Spike here," Rarity said, gesturing to Spike. "Do you really think we'll give you this paradise for free? Besides would you not like a taste of this wonderful dick?"

"Wouldn't you?" Spike asked with a grin. Celestia made her way over to him and knelt before his dragon cock. Celestia looked up at Spike in silent pleading.

"Please."

"You may," Spike said smugly. She thrust herself on his cock, wrapping it within her lips. She lacked much skill, but she had immense enthusiasm, and soon she was addicted to it. "You can feel it, can't you? Feel as your body changes? No other man could ever satisfy you ever again, right? Aren't all Alicorns massive sluts? You'll need me."

"MMMPF!" Celestia moaned, picking up her pace. Beside her Rarity kneeled down on her left, and Flurry Heart on her right.

"There are two futures before you Celestia. One where you're a frumpy, deprived prude, spending every day sitting on that chair, and another where you're the secret temptress ruler of Equestria. Breaking young sluts behind closed doors, making Equestria into a sex-filled paradise. The seemingly perfect Princess secretly corrupts the world. I know you want it, and that you can do it. But only with our help, and only if you agree to serve our Master Spike."

Celestia spat out Spike's dick. Due to a combination of her own fetishes, her arousal and Rarity washing away all her inhibitions, she had no hesitation in her conviction. "Deal."

She dove back into the sloppy blowjob with renewed whorish enthusiasm. As if she was encouraged by her submission, her eyes now filled with sinful delight and Spike could see a spark of Celestia's future wisdom being driven to new schemes to corrupt her kingdom into a land of sex-filled debauchery. Rarity smiled in triumph and allowed Flurry Heart to take over.

"Your future is like a river, it is malleable but some points are fixed. The destination can change but your path must pass by some fixed points. The Canterlot wedding, Nightmare Moon, Twilight's ascension, but the route you take and the steps you may take now can have consequences down the line. But then there's us," Flurry Heart explained, a thread of magic between the two alicorns. The Princess of Time poured the knowledge of fixed points into Diarch's mind and exactly what she needed to do. "And then there's us. We are from the future, yet to be born in your time. You must prepare the world for our Master's arrival, whilst keeping our lives intact."

"Speaking of which, will I keep my memories of the original timeline intact?" Spike asked, intentionally leaving the changed timeline out of his head. He liked to be surprised. "Will Rarity remember both timelines?"

The changes came but the blowjob continued, and Flurry Heart continued to explain Celestia's new purpose. "If you do all that then shift your future in small ways to a radically different future. One better for both yourself and our Master. Can you do that?"

"Well, can you?"

"Yes, Master, I think I can."

Author's Note

Hope you enjoyed that chapter, it was a little difficult to write but I hope it ended up well. The next chapter will have some snapshots of Celestia's new life in certain key events. I got a lot of wonderful suggestions and I think this would help in implementing it.

Sorry if you missed it but I had set up a last-minute poll but it was for a limited-time offer. But nevertheless, we're going to see a hatchling Sci-Twi at some point in the story, taking on a mad scientist theme. Next time with commissions I'll probably not do a poll, but perhaps the one afterwards.
