Mary and Celestia prepare for their fateful meeting with Twilight, hoping that they can negotiate with the powerful alicorn without risking her wrath. But even in the most serious circumstances, the needs of the flesh cannot be ignored.

Dr. Mary Parvotti and Sun Princess Celestia prepare to meet with the enigmatic Twilight, leader of the Six Legends who defended Canterlot from kingdom-destroying threats in its most formative years.

Missing in action due to a tragic mistake from centuries past, the powerful alicorn has re-appeared on a new stage, threatening peace and stability on both sides of the portal. And as Mary seeks distraction within Celestia's bountiful flanks, the Sun Princess works through her own demons, hoping against hope for salvation.

Catharsis

Mary Parvotti hadn’t expected much from the official report, but she’d held out hope that something could be done to deal with the situation before her. Maybe it was just a silly kind of hometown pride, but it would have been nice to know that humanity could actually put up a fight against the potential threat they now faced. Or if not, they might at least meet the end with dignity, leaving enough survivors to tell the tale of the final War that was fought not with bullets and bombs, but with spells and curses.

The doctor tossed her phone to the side as she let her head hit the pillow, feeling her body sink deeper into the white plush bedding of Sun Princess Celestia’s massive bed. She wished she could keep going, diving down into the basement, through the earth’s crust, and out the other side to a place where she didn’t have to worry about existential doom. Or at least, where someone else could deal with it.

Celestia herself was curled on the honey-covered carpet next to the bed, looking almost feline as she lounged with her laptop open next to her head. Mary craned her neck a bit, looking over the alicorn’s shoulder at the long strings of gibberish-looking text on the screen.

Mary couldn’t make out any of the communications, which was expected. As the nerve center of the Canterlot Institute’s ad-hoc operation, Celestia was using a real-time code to pass along info, setting up the complex ciphers with magical incantation instead of computing power. Her horn glowed a soft, comforting yellow while she worked, and the keys of the laptop moved on their own as she encoded and delivered each missive.

Watching the Princess be so infuriatingly diligent gave Mary more confidence than she’d had a moment ago, though it still wasn’t much. The truth of the damning report loomed in her mind, overshadowing even their most recent personal and political successes.

“You think you could survive an apocalypse?” Mary asked, her face illuminated by a single ceiling lamp. Gray clouds darkened the late afternoon sky, and the light patter of rain threatened to lull her to sleep…or it would have, at any other time. She wished she was the kind of person who could sleep in such a situation.

“I already have survived,” Celestia replied without hesitation, never taking her eyes off her tasks. “Didn’t I tell you I was a time-traveller, little pony? Post-post apocalypse. You think it’s a coincidence the name ‘Canterlot’ sounds so familiar?”

Mary opened her mouth, then closed it. “I’m too stressed to even entertain that idea right now. Instead, I choose to believe you’re trying to lighten the mood by fucking with me. It’s not working, but I appreciate the effort.”

“I do like being appreciated. Job well done, then.”

It had been two weeks since Twilight, the renowned leader of the Six Legends, once again made her presence known after three hundred years of silence. Both sides of the portal were understandably in a tizzy, especially since she’d made the overture herself instead of being discovered in the wild. She’d also made a curious, unexplained request.

Twilight wanted to meet alone. With Princess Celestia…and Dr. Mary Parvotti. On Earth, at a specific place and time of the hero’s choosing.

They still had two days to prepare…as much as they could.

Officially, this was a moment of celebration. The lost hero of Canterlot returns after hundreds of years to teach the next generation, or maybe even get the old crew back together for more adventures? At a time of change and upheaval for both pony and human kind alike? Who could ask for a better scenario?

Internally, Celestia put a damper on everyone’s excitement. Without getting into specifics, she made it perfectly clear to Lt. Kurosawa and the others in her echelon that Twilight had skipped out under exceptionally unfortunate circumstances. As a result, the Princess couldn’t guarantee that her former protégé would receive them on friendly terms.

This was a problem. At the time of her disappearance, Twilight’s magical ability and pure strength were already approaching Celestia’s, while humanity still had only the most tentative theories about how they might deal with an out-of-control Sun Princess if it came to it. And now, they faced a being with hundreds of years more experience and skill, who hadn’t had to waste time on silly things like running a kingdom, and who knew Celestia’s strengths and weaknesses better than anyone alive.

The only thing they could do was hope for the best, and plan for the worst. So, the Institute had spent the past couple of weeks in consultation with the Princess, going over scenario after scenario in an attempt to figure out some kind of defense against the powerful alicorn. Could Earth’s combined might even hope to stand against such a creature?

Mary put a hand to her temple. “You saw the report, right?”

The sound of typing paused for the briefest instant before continuing. “I did,” Celestia said. “It’s as I expected. That means we follow her instructions exactly. No surveillance, no weapons, and a five kilometer radius cordon containing only us. I’ll do everything in my power to keep us safe, but…” She left the rest unsaid.

No known defense was the Institute’s bottom-line conclusion. Anything the planet’s forces could throw at Twilight would endanger the entire island, and it still probably wouldn’t do much more than annoy her. At the very least, they had to assume the alicorn was as strong as Celestia in her prime, and that estimation could still be off by an order of magnitude…or more. Even so, the Princess’ strength was the only weapon they could turn to if things went south.

“Your girl’s a damn extinction-event asteroid,” Mary grumbled. “That means you gotta be the nuke that knocks it away.”

“Don’t be insulting,” Celestia said mildly. “I’ve read all of your strategies for such an incident, and I regret to inform you that none of them would have worked. At best, it would have been a nice diversion before the end.” She let out a prideful tsk. “I’m a bit more effective than a nuclear warhead, if I may say so.”

Celestia’s posturing gave Mary a little more confidence. The doctor still felt a vague restlessness, and she wondered at this. Besides the obvious issue staring her in the face, she’d been distracted the past couple of days, and this was unusual for her.

Her eyes swept over Celestia’s equine body as the Princess worked away. Mary’s gaze lingered on that big, pristine, sun-emblazoned ass, and she squeezed her own legs together at the sudden burst of arousal. She realized that they hadn’t fucked in at least a week, and the thought only stoked her heat. She touched two fingers to her lower lips, feeling a pleasing stickiness.

The biologist recalled a phenomenon where animals in distress went into spontaneous heat, seeking out as many sexual partners as possible to spread their genetic material far and wide before the end. Maybe this was something like that. Mary might have been facing death, but one could not live on dread alone.

She watched as Celestia ruffled her pure white wings and stretched her rear legs, languidly working the kinks out of limbs that had been in the same position the whole day. The Princess’ wide haunches jiggled with the sensuous motion, and Mary caught a glimpse of the tight, dark hole within as the round cheeks separated and shifted, gently clapping against the sound of the drizzle outside.

Mary bit her lower lip as she took in the display, and she reached behind, slipping a long finger deep into her own rear entrance. For a while she thought Celestia was giving her a show on accident, so Mary pleasured herself in relative silence, not wanting to ruin the alicorn’s concentration. She only let out the occasional sigh as she imagined everything she wanted to do to those fat buttocks and the puffy ring between.

Celestia’s foreleg slowly wandered to her flank, tracing the curve of her ass with a gilded hoof. Without looking back or stopping her work, she pried apart one massive buttock, clearly revealing her winking hole for a glorious moment before letting go. A meaty slap sounded as the two halves came together again, and the creamy flesh rippled like Jell-O fresh out of the mold.

Mary growled with a fierce hunger, breathing in the raunchy musk that was beginning to permeate the air. It smelled like she wasn’t the only one in distress, the devious bitch.

The doctor clambered down from the bed hands-first, like an animal, and she crawled across the floor to Celestia’s backside, licking her lips as if she was about to partake in a seven-course feast. Mary arched her back and shook her own bubbly moneymaker as she approached, naked as the day she was born, and she could feel the cream roping freely from her overheated cunt to stain the carpet beneath.

The sexy aroma of the Princess’ asshole drew Mary like a unicorn to a blushing virgin, and she eagerly reached out her hands, grasping the fat cheeks in front of her. She hefted them briefly as her fingers sank deep into that tasteful thickness, relishing their weight and majesty before spreading the flanks wide, laying bare Celestia’s forbidden charms.

There was no reason to stand on ceremony. With a moan of contentment, Mary buried her face between Celestia’s buttocks, allowing the heat and smells to fully envelop her. She held herself there, unmoving, and she took in a deep, shuddering breath, before exhaling with a relaxed sigh.

“Someone seems comfortable,” Celestia said in a suspiciously casual tone.

“I was just thinking,” Mary said, her speech muffled by Celestia’s mountains of cake, “you’re a Princess, but I’ve never seen you sit on a throne.”

“Are you applying for the position?”

Mary shifted her head, snuggling deeper into Celestia’s rear cleavage. “Hmm. Depends on the benefits.”

“We have a competitive package. Cheap healthcare, a matching 403(b), and all the deep dicking you can handle.”

“Sounds tempting. Let me think about your competitive package for a while longer.”

Celestia humped her backside against Mary’s face, tickling the woman’s nose with her hungry hole. “Take your time. I insist.”

Mary let a drizzle of spit fall from her lips, covering Celestia’s black pucker with a liberal coating of natural lube. She gingerly sank one finger into the Princess’ anus, and marveled once again at the deceptive tightness and heat surrounding the digit.

The rat-a-tat sound of typing slowed considerably as Mary continued her sport, while soft sighs emerged from the royal throat. Emboldened, the doctor added a second searching finger, then a third, massaging the inner walls of Celestia’s sticky rectum with a slow but insistent rhythm.

At last, the keyboard patter ceased, replaced with bestial grunts as the Princess focused on Mary’s attentions. “Mmm. Slow down, little pony. It’s not going anywhere.”

“Can’t help it,” Mary muttered as she squeezed her pinky into Celestia’s sucking hole. “Your ass is fucking hypnotic. You’ve got no idea how hard it is to keep my cool when I’m walking behind you. Just wanna…spread you open and stick something inside.” Her thumb joined the party and, with a forceful shove, Mary’s whole hand slipped into Celestia’s ravenous asshole.

The Princess grunted with the sensations as Mary went deeper. The wrist dragged past Celestia’s rubbery ring, followed by Mary’s forearm. Muscles that could crush diamond worked the invading limb like it was a prick, and the doctor hummed as she enjoyed the teasing flutters of Celestia’s insides.

“You’ve got your arm…up a horse’s ass,” Celestia panted, stating the obvious as Mary started to move in and out, working up to a proper fucking rhythm while nasty sucking sounds filled the air. “How did you get so depraved, little pony? Ah, fuck…goddamn it…what kind of fucked-up childhood did you have? What went so wrong in your life?”

“I was a horse girl from Montana. Family’s been ranching for half a century,” Mary said, reaching deep into Celestia’s body and touching all the familiar spots as she plunged her other fist into her own cavernous cunt, matching the cadence of her sloppy anal assault. “Damn straight I bounced to equestrian studies in college with all the other horse girls. But I wasn’t like the chicks who creamed their panties at the sight of a fat stallion cock, dreaming about getting their virgin cunts turned inside out by Black Beauty.”

“I find that…hard to believe.”

Mary smiled as her tongue tasted the fragrant juices bubbling from Celestia’s stretched-out hole. “I still had a lot to learn. Thing is, it was the mares that drove me crazy. Their asses, you know? I never could resist a nice, thick set of haunches. Sometimes, I’d hide in a barn near a pasture and jerk off my little cunny, just watching them walk around. The way their tails hid their little holes, the way they’d wink when in heat…and the way they spread themselves for a good mounting…god, I was such a weird horsefucker.”

“Plus ça change…oh shit, keep doing that. Come on, fuck my ass. I won’t break.”

Mary obligingly increased the speed of her pounding fist, knowing that Celestia could take everything she had to give, and more. “You’re one to talk. Look at you, getting off to a human fist up your wrong hole. Does this count as bestiality where you’re from? You feel a tingle in your taint when you introduce your fat Princess cock to another species?”

“You’re more right than you know,” Celestia growled. “Sometimes…I have to drain my nuts, and when there’s no willing partner around, one can’t be too picky. I found this nice pasture out in Kansas…big, with lots of convenient hidden places. Mary, it’s amazing how docile Earth cows are…how pliant. Their bodies are so soft, and…fuck, you wouldn’t believe how snug the pussy is. Like it’s built to please big cock. I may take a herd back with me so I can have bovine cunt on tap.”

A somewhat different scent wafted across Mary’s nose, raw and primal, causing her core to clench in response to the now-familiar stimulus…again, and again, surprising in its insistence, until she was hunching her hips against her plunging fist, feeling the juices ooze from around her stretched cunt lips until the contractions expelled her hand, causing a wash of silky cream to spurt across her thighs. She hadn’t expected to orgasm so quickly, but the revelation of Celestia’s heartland escapades sent her spiraling.

The vibrations in the doctor’s body traveled through her arm into Celestia, and the alicorn moaned in understanding. Her tongue lolled, dripping spittle upon the forgotten laptop as Mary’s adoration of her asshole took on a noticeably shakier feel. “Oh…oh, my. Are you creaming your sloppy twat to the thought of me getting some barnyard cooze? Maybe you want to come with next time, hm? Want to watch me fuck a cow, Doctor?”

Mary nodded at each word as she gasped from deep within Celestia’s flank, enjoying the aftershocks of her come. Actual, real bestiality was a line that she never thought the Princess would cross, but Mary was starting to understand that there were very few limits when it came to the satisfaction of Celestia’s demanding urges. God, she wanted to…she wanted to…

The doctor heard a thump sound, then a slow, fleshy slapping as Celestia chuckled. “No, that’s not what you need, is it? You’re not like my sister, content to sit around and watch from afar. How about I give you a cock, so you can help me out, hm? We’ll take a heifer at the same time. Who knows? You might just find a new…ahhh…addiction…”

Mary was now buried up to the shoulder in Celestia’s asshole, and the rippling motions of the alicorn’s pleasure squeezed with an almost painful intensity. “Yeah, I bet you know all about that, you fat-assed junkie. Come with my arm up in you, go ahead. Take it all. Show me how much you need it.”

“No…not yet,” Celestia groaned. With an effort of will that shocked Mary, the alicorn’s orgasmic throes slowed, then stilled. Her panting breaths eased.

“You are a terror,” Celestia said in a tone that implied the opposite. “Now, get out of my anus and come here.”

Gingerly, with a sucking sound like a 4x4 being pulled out of a mudhole, Mary extracted herself from Celestia’s clinging backside. The tight anal ring fought her every step of the way, not wanting to release the limb from those inviting innards, until with a squish the doctor’s fingers once again felt cool air.

Mary jerked her head out of Celestia’s flanks and she gasped, glad for the chance to take a fresh breath, though she was already missing the intoxicating musk from the alicorn’s taint. “Mmm…first, you need to give it to me straight. How much of that cow stuff was you spinning bullshit? I mean, you do what you gotta do to get your rocks off, but that much desperation is unbecoming, don’t you think?”

“I’ll leave it to your imagination,” Celestia said, her voice strained. “Just know that the lengths I’ve gone to in order to relieve myself would shock even you. The addiction is very real, little pony. But that’s not important right now. I said, come here.”

Celestia turned over onto her back and splayed her hind legs, revealing her full glory. Two basketball-sized nuts fought for space in the smooth white sack between her thighs, sloshing with the backed-up load inside. And above that was the kingdom’s pride and joy: three feet of twitching, pink and gray mottled cock, thick as a pair of arms, slapping angrily against the Princess’ soft white chest.

Mary almost came again at the sight. Her mouth watered as the gently throbbing tip of the royal breeder released a steady stream of thick pre, coating much of Celestia’s upper body with her own sticky fluids, and the smell of semen became cloying in the enclosed space. The alicorn’s hips hunched upward, reflexively seeking out a warm hole.

Mary put a hand to Celestia’s ballsack, feeling the impatient rumbling of its contents. “Oh, look at you! Poor thing! I know we’ve both been busy, but this isn’t healthy, you know?” She lowered her head to those percolating balls, giving a tender kiss to the smooth skin. The salty taste reminded her of the ocean, heady and strong.

“You gotta use the resources available to you, Princess.” Mary stroked the sensitive area between the alicorn’s sack and her asshole. The pure white nuts gave a lurch, and Celestia groaned as a spurt of precome shot across one of her sumptuous eyelashes, coating it thoroughly. The doctor tittered at the reaction. “I’ve been here the whole time. Did you forget? Stuff like this is what cumdumps are for. No need to let your balls get blue, Annie Lou. All you had to do was grab me and stick your cock in my mouth, or bend me over and take some pussy. Don’t even need to ask, you know that.”

As she teased Celestia with her wandering hands and tongue, Mary had a sudden thought. “Hey. Speaking of, why’ve you been keeping your equipment hidden away these past few days, even when we’re alone? Didn’t you say it’s easier on you to keep the spell undone? You suddenly get bashful? What’s the deal?”

“Ohhh, fuck…you beautiful little pony…what you’re doing to me now is exactly why. You’re a distraction…there’s too much at stake, too much to do…but fuck it, I need this. I need you, Mary. Don’t you dare stop!”

The base yearning in Celestia’s voice was a bright new ember, inflaming Mary’s lust to yet greater heights. She’d never met anyone with the Princess’ impossible combination of self-discipline and raw need.

“Unbelievable,” Mary said as she kissed her way up Celestia’s massive tool, stroking every inch of flesh she could reach. “You really can’t help yourself. When it comes down to it, you’d rather laze around with my tongue up your ass than figure out a way to keep your girl from killing us all. Much as I hate to admit it, I’m starting to see Luna’s point of view.”

Celestia didn’t respond right away, and for a moment Mary thought she might have finally gone too far. She was about to change the subject when she felt a subtle shudder in Celestia’s rampant prick, and the alicorn’s panting developed a deeper, more labored edge. Though awash with sticky pre, the doctor’s experienced hands recognized that Celestia’s body and mind were not necessarily in sync, and Mary gave an amused hum against the thick slab of meat as she considered the implications.

She soon made it to the flat crown of Celestia’s cock, where the coin-sized hole at the top continually pumped out an inexhaustible stream of silky fluid. Mary touched the matted fur on Celestia’s chest, feeling her hand sink into the swampy mess, while the Princess watched silently with one lidded, lavender-shaded eye, the other having been sealed shut by a pearly rope.

“I think I felt a little buzz there,” Mary said, deciding to press the issue as much as she was able. “A teeny little lightning bolt, going aaaaall the way from the back of your balls to the tip of your prick.” She traced the path with a devious finger. “It seems a little shy, though. Why doesn’t that cute tingle want to come out and play? Maybe it knows something I don’t. Verrry suspicious.”

Celestia groaned. “Mary…” Her breath caught, and now the look she gave the doctor was wild, even angry. One foreleg went to the doctor’s wiggling butt, kneading Mary’s generous backside like fresh dough, then prodding the entrance of the tight brown hole before working a gold-shod tip deeper inside, stretching it wide around the insistent hoof.

Mary hissed, enjoying the sensation of fullness that she’d been missing of late, so different from using her own fingers. She gnawed on Celestia’s wide flare in teasing retaliation, drawing a gasp from the alicorn.

“Mmm. That little buzz is whispering something to me, Princess. It’s telling me you’re feeling a bit unsatisfied, you see. Evidently, you and Twilight have some…unfinished business.” Mary chuckled. “Well…I guess you might. She probably sees things differently.”

“Fuck…Mary!” Celestia’s hoof worked deeper into Mary’s anus, as if in answer to her provocations, causing steady pulses of cunt cream to spill from the doctor’s cavernous gash. Mary hadn’t realized how much she missed a nice, deep royal buttfucking, so different from taking it in her cunt, and she raised one leg, laying it against Celestia’s oversized cock in order to better spread herself open.

“Yeah, work it. Tear me up, goddamn it. You know how I like it. Imagine she likes it rough, too, or does she need a lighter touch? Ahhh…shit…fuck what she wants, though, right? I think you regret not going straight for the booty, instead of wrecking that cunt. Think her butt is still a tight little virgin hole? Yeah, it must be. Probably crush your tongue to powder if you tried to eat it. I bet her pussy tastes like Pop Rocks and wine, though. Nice and sweet, with a sparkling finish.”

“She’s…never been that kind of pony,” Celestia said through gritted teeth. “Never…had any interest in…the carnal arts….”

Mary lightly ran her teeth against the side of Celestia’s cock, at the same time using one foot to massage her oversized nuts. “Bullshit,” the doctor growled. “No student of yours could ever get away with their innocence intact, you freak. She had to have been at least curious about fucking. Maybe your cute little wide-eyed ingénue only needed a push to fall into depravity. Just a tiny…tiny…push.”

Mary could feel Celestia’s heartbeat thrumming like a V-8 engine in her barrel, sending wild pulses into her rampant, diamond-hard prick. The Princess was almost at the point of no return, judging from the signs her body was giving off, but it felt like she was still holding back. Something was keeping the creature inside from devouring Mary whole.

That would not do.

Mary brought her lips to Celestia’s twitching, white-tufted ear, giving the sensitive exterior a mischievous lick. “Here’s my theory. Twilight wasn’t as absent-minded as you thought. She already suspected what the enhanced poison joke could do, but she still needed some, ah…hard data. So she decided to run an experiment without telling you. Unfortunately — for her — things got out of hand.”

“She wouldn’t…” Celestia groaned. “Too dangerous…wouldn’t want to get others involved…”

“You sure about that? Really, truly, absolutely sure?” Mary asked in a sing-song lilt. “Think back. When she bent over, pointing that tight pony pussy in your direction, wasn’t it wet? Didn’t you see it glistening, dripping juice down her thighs? Wasn’t it winking, just aching to be claimed by a nice, big Princess cock? You didn’t raise a fool, Celestia. Twilight knew what she was doing…she just miscalculated. How could she have possibly known that her beloved teacher was a-“

Mary felt a sharp pain in her scalp right before she was dragged away from Celestia’s ear by a mystical force. She let out a yelp as the Princess turned to face her, and for a frightening moment she wondered if she might’ve become the next poor soul to miscalculate her lover’s limits. However, the plunging hoof in her ass only went deeper into her colon, stretching her out body and soul, and Celestia’s slack-tongued face was bestial in its passion.

“You don’t…know…anything about her.” Celestia bit off each word as if it were forced from her throat.

Mary met the Princess’ gaze with unblinking defiance. “Maybe not, but at least I know where my blinders are. Why not take this chance to find out the truth? What do you think would happen if you showed up to the meeting without hiding yourself? Just walk up hanging dong, without a care in the world. Would she be offended? Or intrigued? Maybe she’d even want to pick up where you left off…”

“No!” The roar shook the bulletproof glass of the suite, and the echoing denial overpowered even the driving rain outside. The doctor’s body jerked unnaturally, and she abruptly found their positions reversed, with her on her back and Celestia straddling like a predator about to enjoy the fruit of the hunt. This brought her face to cock with Celestia’s drooling comeslit, and the Princess made sure the two were intimately acquainted as she rubbed herself all over her lover’s features, uncontrollably thrusting that massive tool as gouts of cloudy pre stained Mary’s flushed cheeks.

“Take what I have to give you, little pony,” Celestia grunted as Mary felt a hoof on the back of her head, hard and unyielding. “And if you bite my cock again, it’s going in your ear. I guarantee I’ll make it fit. Honestly, I might just do it anyway. Haven’t had a good skullfuck in years.”

Mary knew without a doubt that Celestia was not exaggerating or joking, not when she was in this state. She toyed with the idea of giving a nibble regardless, just to see what would happen. Mary didn’t have much time to consider what a magical braingasm would do to her before the pressure on her head became irresistible, causing the spongy tip of Celestia’s fat prick to spread her lips wide before stealing into her hungry mouth.

“Ahhhhh.” Celestia groaned in bliss as she let the head of her cock rest against Mary’s tongue, which dutifully licked the underside of her throbbing flare. “That’s it. Why does it always take a dick in your mouth to shut you up? Mmm…I don’t think you quite understand…the power dynamic in this relationship…oh, fuck…”

Mary wondered if she would like Celestia’s answer if she asked exactly what she thought that dynamic was, and whether or not it was playing out like she expected. Instead, she embraced the Princess’ fat cock like the world’s most vulgar hug pillow, using her whole body to pleasure the entire shaft at once. Celestia snorted scalding breath from her nostrils as she allowed the doctor to worship at her royal altar.

“Twilight is a good pony,” Celestia gasped as Mary worked her gushing cunt against that massive prick, twerking her own big ass with delirious abandon as they drove each other higher. “She’s loyal…and brave…she’d do anything for her friends…and she’s so thirsty for knowledge. I couldn’t ask for a better successor…oh, fuck, Mary, suck my cock. Work for that sweet treat. I hope you skipped lunch…”

If Mary could have smiled around the flare stretching her mouth wide, she would have. The fact that Celestia had been grooming Twilight for eventual rule was new information. She’d been given much to consider…later. For now, she concentrated on the thickening cream flowing into her stomach, preparing herself for the incoming deluge.

“She’s not like me, Doctor.” Celestia almost sobbed with the excruciating pleasure as she hunched her meat deeper into Mary, knocking the laptop aside in her haste to turn herself around for a better angle of attack as she forced the first few inches into that hot, wet throat. “She’s not a slave to her…fucking cock. She doesn’t want to…split open every puffy little cunt she sees. Oh, Mary…she was so sweet, so pure. And I ruined her! Corrupted her!”

Mary mourned the pain behind those bitter words as she took the Princess’ confession, willing herself to become the perfect receptacle for her lover’s sins. From what she’d learned, it had taken a thousand years for Canterlot to grow from a backwater hamlet into a castle in the sky, a model of cultural and political power visible to everyone in their world…and beyond. It was a fantasy kingdom in every sense, an implausible collection of magic, monsters, and people of all types, coaxed into harmony by the implacable force of Sun Princess Celestia’s will over the long centuries.

The second greatest mystery of all was that this castle was shockingly fragile, and the foundation upon which it floated in those impossibly blue skies was a rainbow pillar, each color amplifying the others to strengthen the whole: honesty…kindness…generosity…laughter…loyalty…and of course, the keystone of the arch, magic. But underneath this shining prism was a hidden aspect, an infrared spectrum just out of visible range, without which the entire structure would have crumbled to dust long ago.

“Power,” Celestia rumbled from deep within her barrel as she watched the outline of her cock bloat Mary’s neck and tunnel lower, past her chest and into her stomach. The doctor was in a trance, passively turning into a fleshy sheath for the Princess’ needy shaft as they both sought to sate their lusts in their own ways. “That’s the only reason I could do a damned thing, little pony. All those ideals, so fine, so noble…fuck, your throat, so tight…they’re nothing without strength. That’s the dirty little secret, Doctor. It’s a beautiful kingdom…if I can keep it.”

Only the most powerful alicorn in the history of pony kind could have created a peace that stood unbroken for a thousand years, building a realm whose inhabitants lived in such a magical state of happiness. Celestia’s subjects enjoyed a place of freedom, of fun, of acceptance and joy and love. Above all, it was stable.

Canterlot would not survive another thousand years of stability. That road led only to stagnation and decay.

The Princess bared her teeth, snarling at the inexorable feeling brewing in the fat nuts that were already pulling closer to her body, ready to do their duty to bring forth a new generation. “I can’t keep it up! Mary…Mary, I’m on a knife’s edge! I’ve given everything I have to my kingdom, except its fate. That’s the one gift I cannot grant. The things I’ve done…I shouldn’t be the one to lead my lovely ponies on that glorious path. I don’t deserve it. I wanted to…ahh…leave that for others. I wanted to leave that for…for her…”

Here was the greatest mystery: force alone would not bring Canterlot into the twenty-first century. That would always be important, of course, but equally necessary was the innovative instinct of the young, and the bravery it took to follow those untrodden paths. Twilight represented the best hope of Canterlot’s future, a genius of ravenous intellect with the drive to create a better, brighter kingdom and the might to protect that which she sought to build. It was all supposed to be hers, and but for a moment’s weakness, it would have been.

No longer. Now, that future was in peril, and Celestia would spend the rest of her days doing penance, struggling to keep that brittle yet glorious castle aloft for a century, a year, a day longer.

“I just wanted to make something beautiful!” Celestia cried within the throes of her sexual frenzy as she struggled to pull her mighty cock free from Mary’s crushing gullet. The doctor had never seen her so ready, so strung-out with the urge to come, to feel that elusive pleasure that was like the most mind-expanding high. The length inside her grew still larger — even as she disgorged foot after spit-shined foot from her magically molded throat, it felt never-ending, packing itself into every corner of Mary’s body so that the sights, sounds, and smells of the Sun Princess became her whole existence.

Soon, the broad head of Celestia’s prick lodged against the wide stretched opening of Mary’s mouth, and the Princess growled as she struggled to free herself. Then, with a sharp yank and a pop, using an amount of force that would have broken teeth without protection, the wide flare finally came loose, and Celestia gazed down at a gasping Dr. Mary Parvotti, her face and chest splattered with spit and silky prenut, proof of a load well earned.

The doctor stared back at her lover, overcome with dizzy passion as she focused on that leaking cock tip, and fluids flew in every direction as the Princess stroked herself to her finish, mindlessly acting on that ancient urge to mark her conquest for all to see.

“I have to…I have to finish what I started,” Celestia muttered, her hoof moving faster and faster against her shuddering pink length as she focused her entire being on Mary’s olive-skinned face, flushed with lusty anticipation. “Canterlot has to be made beautiful. If Twilight can’t do it, I will. I swear I will.”

Her words came in a rush, sounding manic, and tears pooled in the corners of her ageless eyes. “I’m going to make a perfect kingdom, Doctor. A pretty, pretty little kingdom, filled with good things. I’ll show you. It’s going to be so lovely…so pretty…so beautiful…” She trailed off as her other hoof possessively caressed Mary’s stained lips, jostling them with her exertions, and her searing breath came in ragged gasps.

Mary’s look was just as wild, just as needy. “You can. You will. I want to see it,” she hissed. “Show me, Tia. Show me how you’ll make a beautiful kingdom…a beautiful world. Start with me.” She opened her mouth wide, extending her long tongue so she could properly accept the Princess’ precious gift.

Celestia groaned deeply at the sight. Mary’s use of the old diminutive, combined with her posture of absolute submission, was about to drive the alicorn over the edge. “Look at me, Mary…Mary…you’re going to sparkle in the sun! Let me make you beautiful, little pony! So…f-fucking…beautiful!”

The slit on Celestia’s flare opened wide, and her cock trembled with the strain of the oncoming load. Mary felt the pulses moving from the Princess’ rumbling nuts up through the shaft, and there was a moment of breathless pause before the dam broke.

Thick lines of sperm blasted free from Celestia’s loins, firing so rapidly that she seemed to be pissing her release in one long ejaculation. With a roar that spoke of complete royal dominance, she covered Mary’s face, neck and tits, dumping a week’s worth of frustration onto the doctor’s passive features, ensuring that every patch of exposed skin was coated in a foamy layer of her rich cream.

Mary’s mask of pearly white only grew thicker as Celestia continued to empty her prodigious balls. Eventually, the Princess aimed at Mary’s mouth, almost immediately filling it full of scalding hot spunk. It tasted like the sweetest, rarest delicacy, and Mary’s tongue swam in a lake of Celestia’s love as the juices overflowed out of the corners of her lips and ran down her cheeks in fat rivulets.

The alicorn gave a lusty grunt with each contraction, savoring every fleeting moment of bliss as her overwhelming discharge continued. Not wanting that pleasure to end, Celestia squeezed the tip of her cock into Mary’s full gob with a sense of anguish, seeking to once again feel the doctor’s devilish tongue against her shaft, now sensitive and raw.

Celestia soaked her flare in Mary’s fragrant soup, forcing out dollops of come as the flat shape formed a tight seal, ensuring that the rest of her load would go directly to its destined place within the human’s belly. She watched Mary’s throat closely as it worked to clear the passage, moving rhythmically in reflexive spasms while her stomach bloated with seed.

“Swallow. Swallow my come, little pony, that’s it. I made it all for you. Drink deep.”

Nasty glucking sounds filled the air as Mary obeyed, taking in the balance of Celestia’s royal issue with the desperation of one dying of thirst. The Princess growled in satisfaction, making sure that every drop was accounted for, and as she wrenched herself free one last time, goopy strings stretched and snapped between her broad cock head and the indecipherable mess that was once Mary’s face.

For a while, Celestia simply gazed lovingly at her obscene work of art. But when the doctor opened her mouth wide, proudly revealing the emptiness inside like a good cumslut, something primal seemed to manifest in the Princess’ actions.

Slowly, methodically, Celestia dragged her cock around Mary’s come covered face, collecting dollops of cream and scraping them into Mary’s searching mouth, to be hungrily slurped down without a trace. Mary opened up again, and Celestia repeated the motions, cleaning her lover’s features and satisfying her craving for jizz at the same time, leaving only a sticky residue behind. All the while, Mary’s hips humped up and down uncontrollably, and gouts of cunt cream flew from her angry red gash as she rode out her own spending, tying her rapture to the Princess’ in unconscious harmony.

When Celestia deemed that Mary had been sufficiently fed, the alicorn rolled onto her side with a heavy thump, just missing the doctor’s prone body, coated with sweat and fluids. Their breathing seemed to sync as they succumbed to their exertions, with Celestia’s barrel expanding and contracting like a bellows, while Mary stared up at nothing, feeling her racing heart start to settle.

After a while she turned toward the Princess, who also seemed to be peering into space, her equine mouth open slightly as she continued to pant. Celestia’s massive cock was soft and quiescent against her matted fur, yet still an intimidating sight. Mary brushed it lightly with scum covered fingers, and it twitched in response, but that was all.

For long minutes, the two lay there in silence, listening to the waxing and waning sounds of rain. Mary glanced at the light gray skies outside the window, judging that dawn was near. Had they been at it all night? She’d scarcely noticed.

Well…that was fine. One could only put off basic needs for so long. And for someone like the Sun Princess, those needs were very base indeed.

Celestia went first, her eyes still focused on the ceiling. “I should not have spoken so freely. Losing myself in lust is no excuse. You’re driving me insane, Mary.”

Mary chuckled. “Princess, you’re old enough to have a spot in the Bayeux Tapestry. Anyone would go nuts after living that long.”

There was a pause. “That’s certainly worth considering.” Celestia fell silent once more, leaving the unspoken floating in the air like a storm cloud. My crime is all the more tragic, then.

Eventually, Celestia spoke again, her voice thick with repressed emotion. “Do you think she will ever forgive me?”

Mary averted her eyes, hoping the Princess couldn’t see her expression.

The doctor considered herself a fairly accomplished liar. Lies were useful sometimes…dangerous, but useful. Yet, some lies were so destructive, they could tear a soul apart. A good liar had to have standards, knowing which was which in any given situation. It wasn’t always easy to tell.

Mary let out a small sigh. Right now, she thought she had a pretty good idea.

“If Twilight wanted you dead,” she said carefully, “she probably wouldn’t send a fucking invitation. I mean, there’s a long way to atonement from there, but she’s given you a chance, which is more than you had a couple weeks ago. Maybe she really is doing some supervillain shit, setting us up for a big fall, but that doesn’t seem like her style.”

Mary raised her arms and stretched, hoping the motion was suitably casual. “In the end, it’s all up to her. I suggest you use this chance wisely, because I don’t think you’ll get another.”

Celestia nodded, lost in her own thoughts. Mary let her ruminate for a while before putting a hand to her snout, drawing her attention. “Hey. There is one thing that might help me answer your question.”

The Princess raised an eyebrow. “And what might that be?”

Mary stroked her rainbow-colored mane. “Tell me about her. Not what’s in the files…tell me some stories. What’s she like?”

Celestia grinned, then she laughed, and the sound was a crystal bell tolling in the darkness. “Gladly. My word, where do I begin? That little pony used to get up to so much mischief…”

The break of dawn gradually brightened the penthouse, but neither of them noticed until the pitter-patter of rain finally ceased and shafts of sunlight pierced the gloomy clouds.
