Quite Contrary

A drop of saliva fell from Twilight’s panting mouth, glistening for a perfect moment in the midday sun before landing with a splash upon Sun Princess Celestia’s rooting muzzle, still buried within Dr. Mary Parvotti’s reddened and sensitive snatch. Mary groaned from beneath the younger alicorn’s soaked haunches as she tried to push the snow-white head away, understanding the need to keep her wits about her instead of succumbing to that talented tongue, but the Princess had not been given leave to stop.

And so, Celestia continued to slurp up the thick cunt cream that bubbled from deep within Mary’s soft-furred hole, even while the tide rolled over the three of them, washing away their combined juices as the Atlantic went on with its ageless rhythms. The Princess didn’t even slow down when the waters covered her face, so irresistible was the compulsion to obey the young alicorn she’d wronged. Celestia and Twilight had both been waiting three hundred years for this penance, and not even the power of the sea would untangle their newly twisted bond.

The smell of brine was intense — much more than usual, even this far out into the surf. The sharp aroma burned Mary’s nostrils, and she found her eyes once again drawn to the shining glyphs of compressed sodium chloride floating in the air up and down the beach, each one depicting a cutie mark from one of Twilight’s companions. The receding tide rolled meekly underneath the beautifully-crafted crystals, as if afraid to disturb their terrible purpose of extracting the salt from the world’s oceans, leaving them sterile and dead.

Mary didn’t know if Twilight was one to bluff, but she couldn’t afford to call it, not yet. Despite the young alicorn’s pronouncement, there was still negotiation to be done. As long as the doctor was still breathing, she could change their fate.

That was assuming Mary wasn’t fucked into a coma. With two insatiable alicorns around, anything could happen.

As the tide went back out, Twilight watched her former mentor devour Mary’s cunt with a deepening look of disgust. “That’s enough,” she finally snapped in her high-pitched voice.

Instantly, Celestia raised her head, addressing the young alicorn like a trained Malinois waiting for instructions. Her mouth was slack, and her rainbow mane was disheveled in a very un-royal fashion, but her eyes were clear and bright as she stared at Twilight with heartbreaking love. It was as if she’d found her true place, there under the hoof of her former student, though Mary hoped the Princess was actually keeping her head in the game instead of indulging in self-flagellation. The doctor wasn’t sure if she could do this alone.

And yet…instead of enjoying Celestia’s servile posture, Twilight’s loathing only seemed to grow. With a snarl, her stubby horn flickered, and the Princess flew backward, tumbling end over end before landing on her prodigious rear a few yards away, her legs splayed apart and her stiffening three feet of cock pointing at the younger alicorn like an accusing finger. Not a sound of protest came from Celestia’s lips as she sat up on the sand; she only stared back at her former student expectantly.

Twilight’s face twisted into an angry sneer. “What did I ever think I could learn from you?”

Celestia visibly flinched at the cruel remark, but she remained silent.

“Pleasure yourself,” Twilight growled, her cheeks still reddened with a dangerous combination of lust and rage. “That’s all you care about, isn’t it? Go ahead. Show me how a so-called Princess finds relief.” Her voice lowered to a venomous hiss. “But don’t you dare come. I forbid it. If you orgasm, Celestia, I’ll consider it a flagrant breach of our agreement. I hope you’ve learned some self-control since last time, and not just for your own sake.”

Mary started to protest, but she hesitated when she saw that Celestia didn’t seem particularly worried. Far from it, in fact — the Princess’ hips flexed, and her massive cock pulsed as it straightened, the flat crown slowly raising higher and higher until her prick became a pink tower, claiming royal ownership over everything in its shadow. Her fat nuts ominously lurched, ready for action despite the admonition. Though she’d already come multiple times today, Mary expected the alicorn could still inseminate a medium-sized village with a few gallons left over.

The doctor heard a quiet gasp, and she swallowed a chuckle. Even Twilight seemed taken aback, intimidated despite herself by the majestic slab of Princess meat before her.

Maintaining eye contact with her former student, Celestia bent herself almost double, pointing the head of her cock directly at her own drooling mouth. Her maw spread a little more, and that eerie tongue snaked out, tasting the dribbles of precome that were already dripping from her slit and running down the shaft, splashing messily upon her heaving balls. Then she opened even wider, almost dislocating her jaw in the effort to engulf the first few inches of her prick, yet moaning in bliss as she worked her head down like a feeding snake, further and further, forcing as much cock as she could into her own tight gullet.

Twilight slowly approached the older alicorn, utterly fascinated by the sight of Celestia swallowing herself. She listened to the loud, wet glucking as the Princess moved her hungry mouth up and down the first third of her cock, twisting her head at each stroke for maximum gratification. Celestia made it sloppy, not caring one whit that her chest, face and crotch were covered in her own secretions. She had been given a direct command, and she would carry it out with consummate skill.

“Aren’t you ashamed?” Twilight asked as she watched Celestia’s self-fellatio, a mixture of awe and horror in her voice. “Aren’t you disgusted? You’re sucking your own p-penis! Is this the wise Princess I devoted my life to? I must have been blind!”

Celestia gurgled something like a whimper as she received Twilight’s insults, but she only increased the pace of her throating, loving herself as if her cock was the only thing in her universe. Mary watched closely, hunching her own hips in sync with the Princess’ motions and wanting with all her heart to tell Twilight exactly what she could do with useless concepts like shame. Instead, she held her peace, knowing that the young legend needed to see for herself the power of unrestrained lust.

Maybe Twilight thought she was immune. Maybe she figured she’d seen the worst of it, on that terrible day three hundred years ago. She wouldn’t be the first pony who carelessly tried to handle Celestia’s passions, only to find their souls utterly consumed in the Princess’ unquenchable bonfire. But now, watching Celestia satisfy her urges with animalistic fervor, it seemed that Twilight was beginning to understand the depths of her former mentor’s depravity, and she wasn’t quite sure how to handle it.

Mary felt a mote of hope in her chest, infinitesimal yet hot as the sun. If Twilight really wanted to know how Celestia got down, they could teach her. They could learn the fuck out of her. It was just a matter of making their arguments appropriately convincing.

“Why don’t you take a closer look?” Mary called out, capitalizing on Twilight’s uncertainty. “She won’t bite…unless you’re into that shit. I’ve got no idea what you’ve been up to in these past few centuries, but I imagine you’ve never seen anything like that…have you?”

Twilight shook her head with wide-eyed wonder as she took in Celestia’s display, causing Mary to release her chuckle. But she resisted the urge to invade the young alicorn’s personal space, in order to guide her with her own human hands — as surreal as it all felt, this wasn’t a dream, and there was no telling how Twilight would react to such a provocation.

For now, at least, it seemed that such a drastic step was not yet needed. Driven by Mary’s words, Twilight squatted to her haunches in front of Celestia, deliberately spreading her thighs so that her dripping, cream-filled twat was on full display. The Princess took in her former protege with a famished look while she crammed another few inches of her massive cock down her own throat, at last reaching the halfway point as she groaned in satisfaction.

Twilight touched her marble-sized clit with a hoof, and she gasped as a spurt of cream squirted from her cunt, painting the lower part of Celestia’s fat prick with her fragrant juices. The Princess’s obscene tongue instantly lashed out of her mouth, collecting as much of the spending as she could reach while she redoubled her efforts, devouring herself as though she would never taste anything better.

“Does this look familiar?” Twilight asked, spreading herself wide to show off the rivers of thick come oozing out of her stretched-out hole. “It’s not quite the same as it was, but I’m sure you recognize it. Don’t you?”

A sudden throb went through Celestia’s cock, and splatters of precome gushed uncontrollably from her overstuffed mouth.

“That’s what I thought,” Twilight whispered as she rubbed herself faster, adding her contribution to the puddle of silky cream on the sand below. “I used to be so tight, you know? Couldn’t even get a crayon into my little slit, although you would have loved to watch me try, wouldn’t you? There’s meek little Twilight all alone in her bed, toying with strange feelings she doesn’t yet understand, desperately waiting for her perfectly trustworthy mentor to give her a guiding wing. I’m shocked you held yourself back as long as you did.”

Twilight reached out and grasped Celestia’s frazzled mane with one sticky hoof. The Princess’ throating became shallower and shallower, until she no longer went up, only down her fat shaft. Celestia sputtered and coughed, and tears ran down her cheeks as her former student began to apply pressure, forcing yet more savory meat past her lips.

“I used to wonder what it’d be like. Losing my virginity, I mean.” Twilight spoke in a wistful, yet bitter tone as she pushed Celestia’s head further, still exposing her dripping cunt to the ravenous Princess. “Who would my lover be? Would they be gentle and experienced, carefully guiding me over the threshold of marehood? Or would the affair be torrid, introducing me to pleasures I never could have imagined?”

“I can guess,” Mary almost said.

“You broke me open,” Twilight murmured, her voice growing huskier as she put her face closer to Celestia’s, almost nuzzling the freakishly stretched-out mouth in her eagerness for a front row seat to an unforgettable sight. “You tore me apart, body and mind. No wine, no candles, no flowers or sweet nothings. Just a cold, hard dose of reality for poor, naive Twilight, all the way to my cervix…and beyond.”

Her other hoof touched a spot high on her trim belly, and she shuddered within the memory. Whether it was one of pleasure or pain, Mary couldn’t tell.

And that was what made Mary’s heart beat faster. The young alicorn hadn’t even seen it coming. One moment, she was having a pleasant conversation with two of the most important ponies in her life, about a breakthrough that might have re-written the textbooks on Canterlot psychiatry. And then, before she could blink, she was being mounted…assaulted…fucked by the one pony she trusted more than anyone. More than herself.

She might as well have been raped by her mother. Worse, she had come there at the end, weeping and struggling in her confused pleasure. Mary suspected that was the part that really messed up Twilight’s head, beyond even the betrayal and physical destruction. If things had been different…if Celestia had approached her student with love and tenderness, instead of blind fuck lust…what might have been? Could such a strange sexual relationship have worked?

They would never know. All that was left was crushing regret.

Celestia was getting closer to the bottom. She retched and sputtered, causing more throat slime and precome to drip onto pulsing balls that were already brewing a fresh, hot load, but Twilight was merciless as she forced the older alicorn to take every sticky, throbbing inch of Grade-A horsecock.

“Choke on it,” Twilight said in a gentle tone. “Choke on it, Celestia. Choke on it.” She pressed with unnatural strength on Celestia’s struggling head, and both her and Mary watched closely as the wide, fleshy base began to fill the Princess’ mouth.

“Choke on it. Choke on it. Choke on it.”

The wet, sticky sounds coming from the bulged-out throat were pure sex to the doctor, and she felt her own heat rising higher as Celestia’s maw went lower, finally touching the foundation of that monstrous prick.

Celestia had consumed the whole thing. Not a hint of mottled pink remained exposed to the ocean air. Her searching tongue laved her own salty nuts, big as beach balls, and they lurched in response, dangerously on the verge of delivering what was sure to be much more than a mouthful.

It wasn’t the first time Mary had beheld such a sight…or the second, or the third…and usually the process took a good bit longer, but she still found herself utterly fascinated by alicorn physiology. Celestia’s horn remained dark; her efforts had been more or less her own, without any magical assistance other than the passive energies infused into every cell of her ageless body. The Sun Princess was a natural cumslut, a cock hound born and bred whether she was giving or receiving, and not even Twilight could hide her grudging admiration.

“Fifty years,” Twilight breathed as she marveled at Celestia’s shameless indulgence, one hoof still stroking her own gushing cunt while the other held the Princess’ rainbow locks in an iron grip. “For fifty years, I isolated myself, attempting everything I could think of to get you back to normal. Because of course, the monster that ravaged me in your chambers wasn’t actually you, you know? It couldn’t have been. Something in the poison joke must have affected your mind. It all made perfect sense at the time. Even now, when I look at your pathetic face, I want to believe it was all a silly mistake that I could have fixed, if only I’d been able to find the root of the problem.”

Mary had to keep reminding herself that there was a very good reason Celestia chose this pony to be her successor. Someone with Twilight’s rational thought processes wouldn’t have immediately blamed the effects of a psychotropic drug on its victim, especially one laid low due to Twilight’s own slack. She would have done her due diligence before rushing to conclusions.

“I tried everything to replicate the effect,” the young alicorn said, confirming Mary’s thoughts. Twilight seemed fixated on Celestia’s overstuffed throat, and she ran a sticky hoof against the steel-cord muscles reflexively working overtime, coaxing the fat shaft within to ultimate glory. “I experimented on myself, as well as others…willingly, and otherwise. My research notes probably look like the ravings of a mad pony, but it was all for naught. None of my other subjects became as…unhinged as you did after controlled exposure to the extract.”

That was the least surprising thing Mary had heard yet, but she couldn’t help pressing a little harder for more info. “Questionable ethics aside, you really just…gave up, after only a half century? That doesn’t quite track with your legendary rep. I gotta admit, I’m a little disappointed. I’ve seen longer clinical trials for dick pills.”

Twilight gave Mary a sideways glance. “If you’re trying to antagonize me, Dr. Parvotti, A) you’re stupid for making the attempt, B) Celestia did it better, and C) it won’t work, anyway. There is no D) all of the above. Would you like to comment further?”

She did, but Mary decided to conserve whatever goodwill she still possessed by staying silent. For the moment.

Twilight gave a disdainful nod as she turned back to Celestia, who had extracted a few precious millimeters of cock from her tortured gullet in a vain attempt to take a clean breath. The legend snarled as if offended by the insubordinate action, and she yanked hard on the Princess’ mane, moving her head up and down like a child playing with a doll.

“I must have made some kind of mistake,” Twilight said as she toyed with her prey. “That was what I told myself. I needed more knowledge…more resources. I had to go to a whole other plane to uncover the truth, once and for all. It took another hundred years, but I did, at last, find answers. They weren’t the ones I was seeking, but science is like that, I guess.”

Mary’d had an inkling that Twilight had spent at least part of her exile on Earth — if you didn’t want to be found, there were few better places than an alternate universe, and it would be simple for an alicorn to stay under the radar in a world without magic, or even internal combustion.

“I get the feeling some very famous scientists found a mysterious collaborator around the 19th century or so,” Mary ventured. Despite the circumstances, she couldn’t help being intrigued. “Not every day you find someone who could call Newton a colleague.”

Twilight half-turned to Mary with an expression of tentative respect. The doctor might have found her scholarly enthusiasm cute — even sexy — if it hadn’t been so tied to tragedy.

“That was rather insightful. The good Sir Isaac was a bit before my time, I’m afraid, but I may have helped Darwin and Pasteur with a few thorny conundrums.” Mary was impressed at how she could reveal such things without a scintilla of self-consciousness. “And I’d love to say that our scholarship bore the fruit that I’d sought…but, no. The secret of Celestia’s insanity eluded me yet. Goodness…a hundred and fifty years wasted. Can you even imagine that, with your human perspective?”

Mary arched an eyebrow. She couldn’t let that fly. “Hey. We may not have much of a long-term view individually, but us apes can do some crazy shit when we put our heads together, you know? Give us some credit; you don’t get Notre Dame without at least a little bit of foresight.”

Mary shakily rose to her feet from the wet beach, suddenly sick of being looked down on. “Ponies haven’t cornered the market on wisdom yet, just like humans don’t have a monopoly on losing control and fucking things up for themselves.” She nodded at something behind Twilight as she brushed sand from her plump ass cheeks. “Case in point.”

Twilight whipped her head around just in time to see Celestia’s balls start to contract, pulling up hard against the shaft in preparation to let loose with an ocean’s worth of salty spew. The Princess’ fat cock thickened, stretching her packed throat even more as the vein inside opened wide. There was a look of delicious terror in Celestia’s eyes, and she struggled in Twilight’s grip, vainly trying to keep herself from tipping over into the abyss.

Twilight’s face was a picture of wrath as she grasped Celestia’s regal horn with both hooves, at the same time spreading herself as wide as possible, almost rubbing her sloppy cunt against the Princess’ treacherous balls as they heaved with strain. “I told you not to come! I commanded you! Are you going to disobey me, Celestia? Are you? Could you truly be so far gone you can’t even follow simple f-freaking directions? Hold it back! Do as I say!”

Celestia shuddered, and she grasped the top of her soft-furred sack tightly with both hooves in a desperate attempt to delay her release, to no avail: the familiar contractions were far too strong, overpowering even the royal grip as the pumping action continued unabated. Celestia’s orgasm was surely inevitable — Mary was intimately familiar with the signs by now, and the Princess had never been one to deny herself pleasure when it was right in front of her. Celestia knew this, Mary knew this…and Twilight likely knew it, too.

That was probably why Mary didn’t panic or succumb to despair as she watched the Princess’ failure. It was the calm of a terminal cancer patient going home to hospice care, enjoying the last few moments of springtime air before the end. If the fate of humanity rested on Celestia not getting her rocks off, then they’d been fucked from the beginning, and it had all been part of the plan. In that case, Mary figured she might as well enjoy the ride all the way to the ground.

“I should send you back to the throne room. Right here, right now.” Twilight’s sloppy pussy drew closer and closer to Celestia’s nuts, until the creamy lips finally kissed the leathery pouch, and the young alicorn began to grind her hips against the round mounds while she grasped the Princess’ horn possessively. It was as if she was working a pole, twerking her tight ass and popping her grape-flavored cunt for a captive audience of one.

“I could do it,” Twilight rasped, her eyes dull and lidded as she danced, indulging in her fancy. “I should. Why not show the whole court what even the youngest Ponyville filly already knows? Let them see you sucking yourself off, drinking your own spending without a care. Imagine the shudders of revulsion from the other Elements…the looks of shocked disappointment. And you’d deserve every…withering…glare.”

Something important was becoming clear to Mary. She decided to take a chance. Wet sand squished between her toes as she took a tentative step toward Twilight, and the sea foam on her olive skin turned her into an insane Venus going for a stroll outside the asylum.

“Kind of a shame you didn’t figure out the whole poison joke thing early on. If you really wanted to fuck everything up for your pretty Princess, weaponizing that stuff in public would’ve been a hell of a play.” Mary put a hand to one breast, pinching the pebble-hard nipple between her fingers as she visualized the scenario. “Would have been amazing to wait for some important audience — maybe that dragon delegation — before cracking open a jar from the shadows and watching the sparks fly.”

Mary recalled one of her many briefings. “What was her name? Ember? I’ve seen her picture. Chick looks like a…tight little package. How long would it take for the Princess to mount that blueberry bitch right there on the royal carpet after catching a whiff of your ganja? Twenty seconds? Ten? Think of Celestia’s face as she starts to realize what’s happening…the horror, the struggle to hold herself back, and then that kinda blank look she gets when she’s too deep in the rut, like a hungry shark sniffing blood in the water. Then would come the screams, the useless fighting to pull her off…and over it all, the plap-plap-plap sound of Celestia getting diplomatic in some prime dragon pussy.”

The doctor heard a warbling groan from deep within Celestia’s barrel, and Mary’s unrestrained laughter carried far over the waves. “Oh, I’m sorry, Princess! Did I just blow up your spot? Is it the teeny little scaly tits, or do you just like ‘em feisty? All the more reason to bounce you out of the castle on your fat ass. What the fuck good is a ruler who doesn’t know how to keep a little goddamn discretion? Lt. Kurosawa had it right. Twilight might’ve saved the kingdom if she just made you go feral where everyone could see it.”

Mary felt the heat in her chest and in her cunt, and she struggled to control her labored breathing. It was so easy to forget why they were there. “‘Course, that probably would’ve started a war or something, but omelettes, eggs…you know.”

Twilight’s hips were a blur of motion against Celestia’s heaving nuts as Mary spoke, but the idea of using her extract to kick off an international incident had her moaning with an even wilder fervor. “Goodness…Dr. Parvotti, how could you be so cruel? I thought you two were partners! But sometimes…mmm…sometimes, cruelty is needed. If I’d only known then what I know now about Celestia’s passions, I would have taken action without hesitation. Better to…oh, oh dear, I’m almost…nnn…better to throw the kingdom into turmoil rather than leave its fate to such a monster!”

And Mary had once thought herself overly impulsive.

Celestia was close. Too close. Her entire body shuddered as she fought to regain the tiniest bit of control over her orgasm, a cause so lost it was whistling Dixie. Far from being outraged at the doctor siding with her former student, the Princess had been carried right up to her limit by Mary’s hypothetical.

But Twilight was teetering at the edge next to her. The young alicorn had said it herself: sometimes, it only took a push to send everything spiraling. One last, good shove would probably do it. That was the hope, at least.

“What did you find out?” Mary’s breathless question was not entirely out of necessity. “Tell me. Tell her. Educate us, Twilight. Hurry!”

Mary’s strident tone seemed to reverberate through the half-sized alicorn like a bell. Twilight began to lose control of her body as she spread her thighs to the maximum, humping her gaping, dripping pussy all over Celestia’s cock-locked face as she painted the Princess’ stretched lips and snout with her foamy cream.

“I…I thought it was me!” Twilight gave a wrenching cry as she tightened her grip on Celestia’s twisted horn. Mary half expected to hear a cracking sound as the ivory gave way beneath the younger alicorn’s hooves, though not even an industrial press could scratch that spire. “I searched my own memories, using magic to go deep into my subconscious. Deeper than any pony has ever dared look at themselves. You would have called it reckless, Celestia…even dangerous…but I could see no other choice. I had to know the truth. For both of us.”

Twilight rested her forehead against her ex-teacher’s while they both barreled toward their endings, and their two horns touched in an intimate way, as if the former student was trying to implant her recollections directly into the Princess’ brain. “I started to see patterns in our interactions, Celestia. Strange words here and there, little touches and caresses that weren’t so innocuous. You remember the games we used to play when I slept over? The funny little ‘lessons’ late at night? Mmm…yes, you do, don’t you? It all became so clear, even though I tried to deny to myself the proof of my own anamnesis. But I’m a scientist. I couldn’t run from the truth forever. And when I finally faced reality…nnn…I’ll never forget the feeling. The sense of betrayal, of innocence defiled. You were grooming me, Celestia, but not just for the throne. Isn’t that right?”

Celestia made a sound like a sick duck as another spurt of precome wet the sands beneath her wide buttocks, and Mary almost came where she stood as she processed Twilight’s accusation. It was a possibility the doctor had kept in the back of her mind since she’d first heard about their relationship, thinking it too obvious — and too fucked up — even for Celestia’s warped mind. But here it was in the clear light of day, and even if the Princess possessed the power of speech, Mary wondered what she could possibly say in her defense. This was more than she expected…and yet, another part of her felt like a fool for expecting anything less.

Twilight released her crushing grip on Celestia’s horn as her hooves wandered across the Princess’ face, touching every disheveled hair on her head as if they were all hers by divine fiat. “That’s okay though, Celestia. It’s all right. I’m much better now. I’ve figured out how to properly slip the reins over my life…and your life, and the lives of everyone you love, if love is even possible for someone like yourself. The desalinization was a delicate plan, requiring a few breakthroughs in magical theory, but I never gave up. I never forgot, and I never forgave. And now…now I’m f-f-fff-frotting myself on your muzzle while your lover watches! Oh, goodness…g-goodness…it’s too much, curse you…come, Celestia! Come! Feed yourself! I command it! Bloat yourself with your own seed, you filthy degenerate! Now! D-do it n-n-now!”

Celestia’s eyes rolled up into her head, showing the whites as she careened past her limit. Her cheeks bulged chipmunk-like as a chunky splurting sound came from deep within her belly, and her massive hips and thighs hunched upward, over and over, battering her chin with her own oversized nuts as they hitched and let go in a regular rhythm, releasing their creamy spend at last.

The Princess’ belly expanded with each flex and spurt of that thick pink hose, accepting wave after wave of delicious baby batter, but those lusty swimmers would be paddling around the wrong pool this day. As Celestia’s midsection rounded and grew to a third-trimester size, the balance of her mighty spending broke the seal of her pink lips against her cock as her load first dripped, then poured from her throat in pulsing surges, freely saturating her chest, stomach, and balls with sticky sweetness.

That was more than enough. Twilight’s whorish moans put the lie to her facade of youthful naïveté as a torrent of cunt cream exploded from her gaping pussy, instantly covering Celestia’s face and body with yet more white, silky juices. She shuddered through her climax like she was wringing every drop of liquid out of herself, and every contraction, every splash of come against her foe’s already soaked-through fur caused an equal response from Celestia’s mighty cock, until the two alicorns’ synchronized orgasms descended into a filthy feedback loop. Their bodily fluids made the sand around them into a slimy swamp, while they gasped and moaned like the mindless beasts they wished they were.

Mary put a hand to her own clasping, furry cunt, reveling in the clenching of her own core as she felt her pussy squirt into her palm — once…twice…godfuckingdammit, three times! — and her thick thighs trembled as she struggled to squeeze multiple fingers into her twitching asshole. But it wasn’t the wild alicorn orgasms that had set her off, nor the devastatingly hot details about the past…not entirely, anyway. Most of all, it was the look of absolute power in Twilight’s sparkling eyes, the dominating posture that demanded perfect obedience, requiring nothing less than willing slavery, complete and unquestioning.

No…it was much, much deeper than that. There was something unique to these ponies, something that made them two hateful peas in an overripe pod, and as Mary rode out her own fierce spending, a kind of orgasmic clarity crystallized her earlier thoughts into a realization that almost sent her over the edge again.

Twilight didn’t really care about the poison joke anymore. After questioning the narrative of her own past, her trauma had gone far beyond a single event, no matter how heinous, so she had come to the conclusion that she needed to take firm control over the shadow that had always loomed over her life. She would not cast light on that shade, obliterating it utterly, for this was not an entity that could be completely destroyed — even if Celestia fell dead right this second, her chilling spirit would remain, dimming the rest of Twilight’s existence with an umbral glow that would never be fully lifted. Instead, the young alicorn would become an even darker shadow, absorbing every stray speck of light as she sought to dominate the creature that made her, that broke her.

And Celestia, in her blind search for forgiveness, would follow her former student all the way to the gates of hell, and beyond. She would do it happily, debasing herself freely, allowing herself to be bound and tamed as if it were the most natural thing in the world…because for the two of them, it was.

Mary had witnessed — and been involved with — more than a few D/s setups in her time. Mostly, it was a game to be played in the bedroom, a naughty bit of fun whose influence evaporated like sweat in the morning light. For a few, it was a “lifestyle,” allowing a constant level of sexual tension, yet carefully controlled and regimented so as not to be too disruptive to everyday existence. There were rules and code words — safe, sane and consensual, as the phrasing went. It was a life of compromise, as dangerous as a roller coaster, with cheap thrills substituting for true pathos.

This was not that. Celestia and Twilight did not cling together because they wanted to. They had been storm-tossed by misadventure before washing upon the shores of the lotus-eaters, only to set sail once again in an obsessive hunt for their white whales, which had become each other. They did not wish for safety; if Twilight ever decided to kill Celestia in a fit of mercy, the Princess would gladly offer her neck. They did not want sanity; they had both lost that light long ago, becoming shells of themselves, hiding their warped personalities under a façade of alicorn pride. And as for consent…well.

The two ruined ponies fed off each other in a parasitic spiral, one taking everything, and the other giving all. This was no longer a relationship as the doctor understood it.

It was a food chain with a Möbius twist, and Mary's cunt bathed itself in glory as the star-crossed beings consumed each other, leaving nothing except flesh.
