~ ~ ~

The school day of Canterlot University of the Arcane had let out not so long ago. The presence of the sun hung high above, even when the myriad of students had hunkered down in the boarding houses and bedrooms to relax after yet more grueling schoolwork as per the rigorous curriculum.

But one student, one very close to the Head Mare and uniquely so, enjoyed the celestial body's presence more than any other.

Twilight Sparkle had been hunkered down in her dorm in Canterlot Castle for quite some time now, essentially since the bell rung. A mural of 'Do Not Disturb' signs hung from practically every square inch of the imposing oak door. Every member of the Royal Guard assigned to her wing of the castle knew full well how dangerous a task it was to not heed the signs. There had been terrible incidents in the past, almost whispered legend of the destruction wrought by a cranky, laser-focused protegé of the sun.

So avoid the dorms they did, not even being near enough to notice an unusually powerful sound dampening barrier surrounding the entire complex that the unicorn had access to. And even if they were to be close enough, they certainly wouldn't be able to hear the rather raunchy noises coming from within, accompanied by fleshly slapping and horse-like whineys...

Inside the student dorms, a corkboard was illuminated in its place on the wall above the bed, and it was utterly adorn with images depicting the Sol Matriarch of Equestria, the Princess of Canterlot, and, by some old religions, the Goddess of the Sun. Celestia, the crown alicorn of the kingdom, and all the available candid photos of her bare feet.

Of all the subcultures surrounding the immortal ruler of Equestria, the one Twilight herself contributed most to was the fetish of the Princess's elusive feet, as her status as the sole prodigy of the ruler gave her unfettered access to the kinds of candid pictures she could snap of those now-sought subjects by a dedicated fetish cult of sorts, one that placed an uncomfortably fervent devotion upon Celestia's feet.

And one of which Twilight was the anonymous founder.

When it started, there wasn't really a strict date to pin. Maybe it was after so many nights of personal tutelage by the monarch herself bestowed onto her personal student. Maybe it was when the burning coals of awful, awkward puberty were stoked in the unicorn by being in the princess's regal presence. Maybe it all stemmed from that first Summer Sun Celebration, when the immortal alicorn rose with the very sun itself like a living deity above her...

Who knew how this grew to be. Only Twilight had an inkling of her own journey, and that was going to stay that way. Nopony could know this about the studious, ever serious, stone-faced shut-in of the university. Who needed friends when the sight of the monarch's forbidden soles filled her heart far more completely?

In the midst of the dingy, hotboxed room, looking up at the enlarged pictures she herself had taken of her mentor's, her royal highness’s feet, far closer and more unveiled than any other attempts at capturing them, Twilight used her hands to feverishly stroke herself off, on her back and legs raised high and twisting in her perverse self-pleasuring. Had the dorms not been concealed in sound-canceling magic, she would have woken up half the castle with her devout noises of moans and high-pitched squeals.

"C—CELESTIAAAAA!! Your feeeet... YOUR FEET!"

She continued her obsessive, repetitive moans to the Goddess, and the true object of her devotion, to the high heavens for nopony to hear. And as always, Twilight raised her hips in a final thrust that gave way to her climax of the evening, aimed toward a particular image far bolder than any other: all ten of Celestia's exposed, freshly pedicured toes, just unveiled from a tug of her dress upwards. Those enlarged images of such nut-worthy tootsies were splattered in what might as well be the thousandth load of Twilight's perverted horsecum since those toes were snapped by a very cleverly composed Twilight last week at the Grand Galloping Gala rehearsal dinner.

Recovering from her orgasm of devotion, Twilight picked herself up from the floor and tread towards the cum-drenched toes, looking upon them as she would a lover amidst the haze of post-coital bliss. Getting an inch away, Twilight then licked her cum from the photo, panting breathlessly as she did. More ropes of cum flew from her softening cock in the act.

"D—Dear, darling Princess... Who I wouldn't kill just to taste those delectable... holy... SUCKABLE TOES of yours...~"

Licking her lips, the faithful little pupil let herself fall to the mussed sheets on her dorm bed, letting her cock shrink back into her sheath. How long had she been in her dorm...?

—————

Later that evening, about 8 p.m and well after Twilight's recovery from her 'nightly ritual' as she phrased it in her meticulous itinerary, she was called upon by the princess to join her in the throne room. A common practice, as her Highness needed a reprieve from raising the moon and often called on Twilight to join her in those vulnerable times. A fact much prided by the perky, assured unicorn.

Walking into the room, the vibe was immediately different. None of the stations of the Royal Guard were manned. The chandeliers were haphazardly kept, making the room dimmer than usual. And sitting at her drafting desk instead of her throne on arrival like usual, Celestia of the Sun greeted the unicorn prodigy with her warm smile and a wave of her hand. Something that made Twilight's heart flutter every single goddamn time.

Trotting up like an excited schoolfilly on her first day, Twilight bowed deeply before she took her rightly seat on the opposite side of the desk.

"Anything on the agenda tonight, Princess Celestia?" She asked, already beaming in her royal presence.

"Oh, only an exercise in academics... Come, join me. Pick up a scroll and read with me."

The princess spoke in such a lovely, melodious voice, like the songbirds of Equestria strove to match her audible beauty. Listening to her speak made Twilight positively melt where she stood. Thankfully she had enough wherewithall to venture her hand out and grasp a scroll of papyrus to occupy herself with before her nerves got the better of her.

For a while, the night was nothing special in particular. The subject of the day was... historical erotica, of all things. Well, it's not like Twilight knew nothing of the topic, especially not regarding certain... focuses. But what was the royal protegé if not professional about academic studies?

Studying the essays and manuscripts like a dutiful student, the fidgety little fledgeling was so far buried in the paper of her reading that she failed to notice the monarch now up and about and received a heart-beating startle when she glanced up and saw Celestia sitting before her with her behind on the edge of the desk, her auroral eyes set on the papyrus unfurled in her fingers.

"Quite the interesting turn, don't you think, Twilight?" The princess asked, clearly expecting Twilight's informes opinion. "On the Lunarian golden agw of taboo writings. They were quite the raunchy group of authors last I recall."

Twilight's brain spazzed out in that moment and her only formulated response was a series of stuttering vowels and unbecoming noises.

"Please, my student, it's not postgraduate alchemy here." Celestia rebuked rather dryly, a humored grin creeping up her cheeks.

"S—Sorry, Princess, I just—" Stopping the verbal vomit and gathering herself, Twilight gave her usual type of answer. "I do think there was a noticeable shift in erotica following Nightmare Moon's banishment, from general fantasies for every reader to a focused drive to depict the Mare in the Moon as some sexual deity that preys on lewd dreams and serves as a sex icon to the lunar followers."

"That's the Twilight kind of answer I've come to expect." Celestia's praise was so warming and comforting. Like a drug to the unicorn. "Could you speculate as to why that is?"

"W—Well, um.. Forgive me, Princess but your status as a goddess in the early religions was that of a matron, the motherly aspect of femininity. The Moon was therefore the incompatible aspect, sexuality. Plus, the banishment brought about a rather puritanical streak in the early Equestrians, and that always leads to an equal push from the opposite side of the board." She really hoped her answer didn't tip over into blasphemy against the throne.

"That's the exact answer, Twilight."

Twilight blinked. Well that was fortuitous.

"My student, I personally witnessed this change in attitude when I ascended as the sole monarch. Being regarded as a deity was something I wasn't letting slip me by unchecked or misunderstood by myself. It's not like I could encourage them to allow me to represent all aspects of femininity." Celestia rolled her paper back up with a flick of magic and an exasperated chuckle.

"Oh, don't sell yourself short, your Highness." Twilight murmured saucily.

When Celestia giggled at her response, Twilight first started nervously, but settled when the princess found humor in her unprovoked comment.

Then, the monarch turned around, reaching over the desk.

"Excuse me, I need a quill here shortly..."

Twilight's mind had already checked out. Her eyes, two beaming lasers of immense concentration, found themselves locked unmoving onto the downward sight to behold, an inconceivable opportunity.

Celestia was leaned across the desk, having to be on her tiptoes to do so. That left the bottoms of her feet, both her soles, completely exposed from the imprints of her well-worn sandals and showing to the tiny mare behind her all the pearly skin of her feet. Twilight could hardly believe such a photogenic sight was right before her eyes. And by the sounds of it, the Princess wasn't finding that quill anytime soon.

A quick and silent spell brought out a holographic interface, a capture screen locked onto Celestia's candidly exposed soles. Twilight took what must've been dozens of snapshots in the precious few seconds she had the spell activated. She dispelled it with haste before burying herself in reading once more. Nothing to see here, just an academic nerd enjoying some analysis of godly smut...

By the time Twilight dared to peek around at her mentor once more, she was right back to gliding around the perimeter of the reading light of the lantern, completely unaware of the sheer act of degeneracy committed right under her toes— HER NOSE. That's what she meant, her nose.

"What seems to be the motivation for the eventual acceptance of Lunarian erotica, my student?"

Shoot, another question.

"Wasn't it the liberation movement started by queer authors of all genres? I think that's a night of research all on its own..."

Celestia looked... mournful in that moment. Her eyes now looked at nothing in particular. Whatever papyrus scroll she held, she did so solidly in both hands. Her brow became furrowed. Twilight shrunk back in her seat. "Is... something wrong?"

The monarch silently rolled the scroll into a tight wind, more then enough torque to shut it and almost tearing it. She breathed deeply before magicking it away.

"Repression is a grave sickness, Twilight. Do you understand?"

The unicorn had no words for an entirely different reason.

"I bear some of the responsibility for those ponies bearing the fate they did. I was distracted by things other than my people's well-being. I vowed to never foster an environment where anypony had to hide their true selves. I fear how it could regress to such folly in the future."

"Your Highness," Twilight spoke up finally.
"Your role is as good as you could've made it. I can't think of a single decision you should have made differently."

"Even with you?"

That confused Twilight. What did she mean by that? How could she ever wish to be treated differently by someone so gracious to her?

"Oh, ignore me," Celestia soon waved her hand dismissively. "I fret far too much. You make me prouder than any student I've mentored before; that ought to speak to my effect on your development."

A deserved moment of self-recognition, Twilight thought. She felt she wouldn't have reached nearly the heights of her studies without such divine guidance. And it didn't hurt to have such an effective if secretive stress relief in the same source.

The night resumed once more with normalcy past their conversation. More reading of queer literature, more thoughtful discussions on the topic and Twilight displaying her encyclopedic deduction, and more and more slow and steady descent into the sleepy, quiet hours of the late night. Come the hour before midnight, and Celestia was back in her chair, cozied in just as her student was.

Fighting off a shiver, the princess lifted her horn and fired off a signal to turn the candle fire up a notch, sending a wave of warmth down the sprawling length of the throne room.

Twilight exhaled appreciatively now that she didn't quite feel the night air creeping in through the gaps in the window. Such protective warmth the princess was capable of, even against her holy opposite in her territory. She only hoped her love for the monarch could be felt as acutely. Looking up from her book, she noticed a very invested Princess pouring herself into a particular tome. Her thoughts changed direction abruptly, almost at breakneck speed.

Was her Majesty... actually interested in this? Not just in an academic sense, but a... libido sense? No, perish the thought, she must. The Princess has never been that kind of mare. She's an entirely different breed of pony, far above those kinds of awful thoughts! Plus, she had never expressed anything resembling libido in all her years of mentoring from her, and there are no children to speak of from her holy royal bloodline, so...

"Quite invigorating... I say, the Lunarians know what they're doing with their quill and parchment..."

If Twilight's face got any hotter and brighter than it became after hearing THAT, Celestia would need to turn the braziers down for her own fire would overwhelm them.

"I—I—aiyiyiyi don't think.. I have that book out o—over here. What are you— ahem— referring to?" Twilight somehow managed to pull herself together to string together a coherent combination of words into her inquiry.

"Oh, this juicy excerpt from about a hundred years after the founding of the cult, of the lunar followers' devotion to the Mare in the Moon. It's remarkable how... detailed the writings are. I must say I enjoy them, barring the obvious associations of course."

Twilight could swear she heard steam exiting her pinned ears. She buried herself in the glossary of her book in a desperate, intellectual equivalent of a cold shower. Oh, those are the terminology entries describing the lewd words in the book, THAT won't do—.

In her scramble to ignore the burning in her body, the monarch took her nose out of the tome's crease and drew her eyes on the snug ball of nervous unicorn sitting across from her. Please don't ask to engage, dear princess—.

"I find this quite interesting... Here, look at this passage."

Suddenly, Twilight was thrust into a new document's contents by the monarch's magic levitating it up to her, thankfully highlighted by the same magic. How kind of her for the neurotic fledgling— holy hay there are toes in that book.

Plain as day before her eyes and given special attention by the Princess of Equestria herself was a passage by a Lunarian cultist's feverish declarations of devotion to the Moon Goddess's divinely beautiful feet, in far more flowery and eloquent speech than even Twilight could muster in private towards her affections. Hearing how brazenly this devotee verbally *slobbered* for Nightmare Moon's toes was enough to make a Manehatten streetwhorse blush.

"Quite the intriguing fetish to link to the Lunarian image of sex, don't you think? A focus on the Moon Goddess's feet is unique, but not unheard of in the erotica of Equestria's deities. There's always been a significance placed upon a god's feet, as their connection to the same ground that every other mortal walks. Any thoughts on this phenomenon, my student?"

Twilight had to play off her utter wordlessness as an engrossment of the material in front of her, which wasn't... entirely misrepresentation. She DID have a very easy time reading these passages and disections, especially the previously unseen excerpts of Lunarian writing. That was some devotion, alright.

Then Twilight caught the monarch's gaze in the corner of her eye, those thick lashes batting in anticipation for her studious response. The unicorn could feel sweat rushing past her brow, illuminated by her magic as she flipped through the pages back to Celestia's place in the literature. She could NOT let the princess have any clue as to her deepest, darkest rituals.

"Ohh, I—I reeeally don't think I'm that qualified to speak on such— such matters, your Majesty. I think I'll keep reading a—and educate myself! Yeah, yeah, that's the best course of action right now..."

Twilight tried to bury herself back into the tome, but Celestia raised an eyebrow above lidded eyes and asked a very dry question with just an expression. "Twilight, you only decline to engage when you have hangups about a subject and its literature."

That was a clue!?

"You also only use 'your Majesty' when you're not being sincere."

THAT TOO!?

"What troubles you this time, my faithful student? It's unwise to let those feelings go unchecked. Remember when the Equestria Journal of Biology published their findings on draconic upbringing and you threw a fit in the lecture hall with me there?"

Oh yeah, that was bad. Twilight almost had to get bailed out of jail for the way she reamed those colonialist pricks. Maybe... she could divulge to her mentor? Drifting the tome down just enough to reveal her earnest gaze to the monarch, sandwiched between her straight bangs and the leathery bindings, the prodigy took a deep breath and braced herself.

"I... I can answer the question, Princess, I just feel uncomfortable with the knowledge I have on... such a subject." Twilight admitted, flicking her gaze away.

"Oh, Twilight," Celestia smiled gently in bemusement. "If you yourself are drawn in by the Lunarian feet-focused erotica, there's no shame in that. Why do you think I am so eager to speak with you on such material?~"

Twilight met the princess's kind, matronly gaze with wide eyes under a furrowed brow. She huffed through her snout quite forcefully.

"I'm sorry what."

Celestia smirked. Rather deviously too. "Do you think an immortal princess has no sex drive, Ms. Sparkle?"

Twilight slammed the tome closed, hiding her face with her arms raised to hold the covering tightly. The burn of her blood rushing throughout her slender body only got hotter. She couldn't bear to look her Majesty in the eyes after such words were spoken. They echoed in her head in that same, smoky tone the princess had said them in.

To her surprise, the tome was nudged downward and revealed to Twilight the sun-dappled face of the monarch above her, her body leaning across the desk and getting very close to her student. The toga that wrapped the alicorn's front and waist was clinging for dear life to her tightly-bound chest, and her voluminous mane of pastel raindow was cascading down her shoulders and draped over her large frame. Her eyes held auroras within the honey-colored irises. It was all enough to suck the breath from Twilight's lungs like a vacuum.

Celestia made the next move, not expecting a petrified unicorn to be proactive in the face of a deity. She took her student's face in her palm whilst her other hand kept her balanced on the edge of the desk. Twilight's breath came out of her ajar maw in a jittery yammer at such a touch. The monarch's hand was comfortingly warm to the touch. She looked upon Twilight with those eyes holding all the knowing in the world, eyes from which nothing could hide. Twilight was certain Celestia could feel her heartbeat within her flushed cheek's capillaries.

"You love me. Don't you, Twilight?"

Twilight could cry at such a wistful, beautiful tone in that voice of hers. Her mouth hung open before the princess's gaze, the smallest squeaks of attempts at speaking bleating from her maw.

"More than that, even. You worship me, like a goddess."

"You are a goddess."

It was the most conviction throughout all Twilight had spoken with tonight that she declared that to Princess Celestia. Yet her devoted declaration was met by a retreat of Celestia's hands, something that sank Twilight's thumping heart into the depths of her stomach.

Though Celestia pulled away, her gaze never left her, nor morphed in any way. Her hand moved back to the tome and returned it to her grasp. The only change in the monarch was her leaning back into her seat and opening the tome. Twilight finally took in the title illuminated across the leather bounds:

'𝐓𝐇𝐄 𝐋𝐔𝐍𝐀𝐑 𝐆𝐎𝐃𝐃𝐄𝐒𝐒; 𝐀 𝐂𝐎𝐌𝐏𝐋𝐄𝐓𝐄 𝐇𝐈𝐒𝐓𝐎𝐑𝐘.'

Twilight watched how the princess tenderly riffed through the pages. What special thing was held within those scrawlings that she regarded so thoughtfully? What was Twilight missing?

"That was honest. That's something I find quite rare in you, my student."

Twilight blinked, drawn out of her trance by something so blunt out of the monarch's mouth. "What..? I—I've never lied to you—!"

"No, of course not. You couldn't even if you tried. I meant to yourself." The bravado in Twilight's self-assertion gave way to defeat. She sat pretty and still on her chair, waiting to be called into the principal's office for some unforseen social crossing. It wasn't often, even in magic kindergarten, that she should be subject to a visit with Celestia under such pretense. It terrified the unicorn.

"You hide parts of yourself away in recesses you think are sealed and hidden. I see them beneath the smoke and mirrors, and the distortion of your perception of yourself. You love in ways beyond your academically-tracked mind, in baser, simpler ways like other ponies do. You engage with so much more than your studies, even if you decline to admit it."

"W—What do you.. mean?" Twilight twiddled her thumbs in anticipation. She didn't know if this was a lesson or a lecture, despite the princess's gentle-as-ever tone.

"To be blunt and relevant, reading about moon cult porn turns you on."

Twilight didn't know if she wanted to scream to the heavens or perish on the spot. Her face turning a brilliant shade of magenta only added to her condemnation by the Princess's words.

"It's nothing to be ashamed of, Twilight. We all come to confront our libido at one point or another. I know I did reading what the Lunarians would do in honor of their goddess's holy feet... Hff. ♡" Celestia's voice became just the barest bit raspier upon that last statement. Twilight flailed in a knee-jerk reaction and almost took the papyrus scrolls with her frantic arms.

"I—I don't need a lesson in sex positivity with our erotica research, y—your Highness!" Her tittering and choked-up bellow left Twilight embarrassed and Celestia bearing down on her with her honeydrop orbs.

Twilight feared the worst, especially when the monarch closed the tome and carried it with her around the desk to seat herself upon the ledge, looking back down at Twilight.

"Do you think it's improper to expose my ears to vulgar topics in vulgar ways? Or is it the misconception of my matronly position?"
When Twilight didn't answer, Celestia leaned down, a hand put on her student's knee. Her smile didn't waver at all. "If you wish to dispel that misconception, I can show you what I really am like as a living, breathing mare. Up close..."

Her slender fingers slipped down the crevace of Twilights legs...

"And personal. ♡"

Without another second to process just what the Holy Goddess of the Sun was suggesting to a mere mortal mare, Twilight had *thrown* her legs apart, her concentration entirely on the looming monarch and not at all on bodily discretion. When Celestia gave a melodic giggle for the young unicorn's apparent eagerness, Twilight gasped in realization and slammed her knees together, making a deep clap ring out from her thighs. Unfortunately, it was around the monarch's hand, and it wasn't tight enough to keep her from slipping up the unicorn's uniform skirt.

Twilight gasped as the touch of the sun became known to the stiffening, turgid mass thinly veiled in the fabric of her panties, and her expression of utter bliss was only matched by Celestia's own magma-smoldering gaze, complete with a batting of those thick, mascara-ladden eyelashes.

"I want to hear you say you want it before I continue. Enthusiastic consent is a key part of my seduction plan here so... do you want this?" Celestia almost begged for her pupil's honesty in those words. And Twilight couldn't lie to her mentor even if she wanted to.

"I want this so much more than you could ever know, your Highness... PLEASE show me, teacher..." Twilight was short of breath, flushed in the face, and spreading her legs as wide as her seat would allow, helped by a healthy flexibility from childhood gymnastics. At the point of releasing Celestia's hand, the princess nudged the skirt she wore out of the way and unveiled the panty-busting erection swinging from her thigh's confinement. The princess caressed the long and lengthy shaft of Twilight's, fingers pointed down and her palm forcing the stretched fabric to press back into the hard-as-diamonds log erecting from between her pupil's plump, soft legs. The student was pinned to her chair, arms beside her, using her spread legs to pump herself up and down, shamelessly grinding against her mentor's gentle, loving hand.

"How long has this throbbing monster been aching for me, my darling pupil?" Celestia's breathy voice seeped her inquiring words into Twilight's ears, only making her hump into the air harder and quicker.

"S—SO FUCKING LONG, holy SHIT..." The poor unicorn panted, squeaking out her answers as she fought off the easiest orgasm of her life. The stretched fabric draped tight over the ribbed crown of her tip was soaked completely through by her precum. Her eyes were rolled back into her head from the constant stream of blissful touch electrifying her nervous system.

In a stunning turn, Twilight no longer felt the monarch's hand. She was left humping the air like a dog. Her vision corrected and looked upon the alabaster goddess sitting above her, one of her feet pressed to her chair and dangerously close to her nethers. Before Twilight could ask about this, the princess had pushed her away, giving herself far more leg room. And with that extra flexibility...

"EEP—!!"

The unicorn's aching, stiffened shaft felt the soft, pillowy embrace of her princess's unearthly soles, one set of toes grasping the sensitive tip and the other splayed down the curve of her cock's shaft. As the latter slowly slid up and down the pulsating veins, the former gripped the ruined panties and snapped them from their stretchy predicament. Now completely exposed, Twilight stared with eyes the size of dinner plates as Princess Celestia smeared her royal feet in the gooey, sticky slime of her student's precum.

"Oh, I see what I've been missing... Smut is nothing compared to holding this monstrous horsecock between my feet..." As Celestia marveled at the joys of her footjob, Twilight gaped with her mouth ajar as she realized just how HUGE Celestia's fucking feet were.

Her cock was big. Like, far above average big. That had never been in dispute. Locker rooms in college buzzed with rumors of the royal protegé's swingin' horsedong. And the monarch's sole alone matched her length. Not to mention how her sole doubled the width, and her long toes added even more to the length and the way those fat piggies wriggled against her veins and how fucking godlike her soles felt and—.

"Cum."

Twilight blinked her eyes wide open, looking Celestia in the eye in a moment of vulnerability.

"Spray those feet-fueled ropes of marenut for me, Twilight Sparkle. Prove your devotion to these big, phat royal FEET. CUM!"

"M—MYYY GODDESSSS—!! HYUHHH"

The explosion that followed was unlike any orgasm Twilight could hope to achieve before this. She blacked out, hard. When she finally came to, she awoke with fluttering eyes to the sight of her Royal Highness, sprayed in countless thick, chunky ropes of her cum, thickly draped over her heavenly body, on her face, in her hair, and especially drizzled over her scrunched toes and seeping into the wrinkles of her soles. And Celestia was licking some of that voluminous nut from her fingers. When she noticed her student back in her head, she flashed a pleased smile paired with such utterly knee-wobbling 'fuck-me' eyes.

"Good student as always, Ms. Sparkle. A+... ♡"

Twilight blacked out again.

Author's Note

A longer form story from an inexperienced author? Say it ain't so!
This will have a whole lot of stops along the way to the eventual endpoint of the series, and a dumping grounds for all the kinky ideas around this very specific ship dynamic. Next is a direct followup once Twily comes out of her post-nut coma.
