A Perfect Little Worst-Case Scenario

Celestia had never even asked the mare’s name. This didn’t actually bother the Goddess, though she oddly felt that it should have.

She only vaguely noticed the swift appearance of a pair of ponies who cleared away the cart and the mess of the food, and even closed and re-latched the window. They were always utterly silent and efficient in their efforts. Perfect.

In any other situation, she might have already been fucking one of them into floor as a reward for a job well done. Right now, however, there was only one pony she wished to see.

“Witch,” Celestia called. “Show yourself. We need to talk. I know you like to watch me play around, but there are weighty matters that beings such as ourselves must occasionally attend to.”

A flicker of shadow momentarily darkened the brightness of the room. Then a soft, breathy voice emerged from high in the corner above the bed.

“I was waiting for you to offer me a bite, selfish cunt. It’s hard to get your rocks off on an empty stomach…although I managed somehow.”

Something took shape near the ceiling, gradually forming into a slender pony who drifted in midair like a mote within a shaft of sunshine. The ruddy orange creature’s spread wings and spiral horn marked her for a full alicorn, though instead of a cock, she sported a pussy slit that looked as tight as a virgin’s…a cute, yet false affectation Celestia knew was purely for the Goddess’ benefit.

The eyes beneath the alicorn’s sunflower mane contained no irises. They shone with swirls of near monochrome light as she peered down at Celestia with amusement — at one moment bright white, and another stormcloud grey with flecks of gold — offering the barest glimpse of the power within. It was a power that few had seen unleashed, and none save Celestia had survived.

The pony landed gently upon the freshly made blankets of Celestia’s bed. She stretched out like a jaguar, as if she were in her own home instead of the most private sanctum of a living deity, flopping onto her side and patting the space next to her in invitation.

“Come on, then. We can attend to your weighty matter and talk about the other thing, too. An omnipotent goddess like yourself surely knows how to multitask, hm?”

“You were so much cuter back when you were afraid of me,” Celestia rumbled. But it only took a single gallop for the Goddess to leap into the bed beside the strange pony, gratefully nuzzling her head into the soft hide of the Witch’s sunset barrel. “And we both know you don’t need to eat, so stop fishing for sympathy. You’re the last magical alicorn, Witch. Try acting with appropriate gravitas every once in a while.”

“I did,” the Witch said, teasing Celestia’s mane with familiar tenderness. “For a couple hundred years, remember? It was dreadfully boring. That’s why I dispensed with all the tiresome ceremony. I’d much rather work on my theories than play at being a religious icon.”

She stroked Celestia’s massive cock with one leg, watching it slowly grow from her loving touch. “That said…I’d be happy to wear the habit again if you want. A little blasphemy for old times’ sake might be just what you need.” She blew a gentle breath against Celestia’s ear, chuckling at the resulting shudder. “It’s been a while, though. The outfit might be a little tight on me.”

“Harlot,” Celestia replied, but her voice was husky. Her hips began to move as her cock sought friction against the Witch’s thighs. “I’ll have you flogged for such degeneracy.”

“Is that a promise?”

“Perhaps. After we figure out what happened.” Celestia pulled her face out of the Witch’s breast, taking a deep breath as the morning’s events intruded upon her mind. She looked up at her companion, giving a look of such vulnerability it would have made her unrecognizable to her trillions of followers. “You felt it, didn’t you? The emotional response? Why didn’t you predict that?”

“I warned you to expect the unexpected. Setting up a beachhead in an alternate universe containing another version of yourself isn’t as simple as opening a portal and stepping over. You saw the result after the first experiment with the fruit, but the omniscient Goddess Celestia said she could handle whatever came across.”

The Witch idly stroked Celestia’s ass, consciously steering clear of the winking hole between the doughy cheeks and making the Goddess whine in annoyance. “Now that you’ve had a taste of the possibilities, do you want to keep going? You have everything a pony could ever need right here…with me. Is your drive for subjugation so insatiable still?”

“A born conqueror does not stop at only one plane of existence.” But Celestia had heard the recrimination in the Witch’s voice, along with the deeper love behind it, and she forced herself to re-consider the path she’d chosen. Certainly, when her companion had hinted at the feasibility of breaking the Axiom of Singularity within the new dimension she’d discovered, Celestia’s excitement had been boundless. She’d wanted to send an expeditionary force right away, relishing the prospect of a fight with a warped, alien version of herself.

The Goddess’ victory was a foregone conclusion, of course. No knockoff, bargain-basement Celestia could possibly stand against the real thing.

“But the multiverse could not abide such a conflict,” Celestia muttered to herself. According to the Witch’s research, breaking the Axiom would not be an easy task. The powerful alicorns’ simple existence in the same dimensional envelope could annihilate one or both, and the repercussions might shake the very foundations of reality in ways that were impossible to predict.

Might. Could. Impossible to predict. There were so many damnable uncertainties. Yet, there was no gain without risk. And the Witch had discovered some breakthroughs that raised their prospects significantly.

They couldn’t send Celestia over herself, or anything physical from their current realm, without courting disaster. However, energy was a different matter. The emotional essence that all living things possessed could be traded in a kind of equivalent exchange. The Witch could send over the magical wavelength of an object, and they would receive another back.

The interesting part — the cause of, and potential solution to, all their problems — was the fact that these swapped magical energies were forever linked across dimensions. When the Witch and the Goddess first experimented with sending the essence of the small, citrusy aphrodisiac fruit still used by some of the more old-fashioned ponies to the other side, they had no idea what they would receive in response. They certainly didn’t expect a slow, steady, driving kind of music, piped directly into the conscious minds of every pony on the planet.

The Witch had explained it as some sort of universal translation. The singular vibe of the fruit came across as a sound, which changed over time, until the sensual music had become a part of New Canterlot culture. Even its name had eventually reached them, though the word had no meaning to anyone on their side.

The alicorns could only speculate about what the alternate dimension received. Some other kind of sensory input? An aroma, or a color? Or maybe an infusion of pure magic? It was impossible to know. Whatever it was, it was likely affecting that far-off civilization as much as the sensual bolero had changed theirs.

Celestia hated to admit it, but whatever strange intelligence truly ruled the multiverse knew very well what passions motivated the beings in the small part she’d carved out for herself.

She cupped the Witch’s cunt with a hoof, finding it wet and sticky, and as she spread the delicate petals of the tight slit, exposing the reddened interior to the air, she was pleased to hear soft answering groans. Tit for tat.

“What…ohhh…what are you doing?”

“Multitasking.”

“Mmm…as nice as that feels, I’ll need more. Much more.” Celestia’s pride was already growing to its full majesty between their two bodies, and the Witch tried to frot against it with increasing urgency. “If you want to reward me for my service, give me cock. I…I need it. You know how I get without it.”

“I do know,” Celestia sighed. “The last time you got all pent up, every priest on the planet dreamed of the same psychic revelation involving myself, a dolphin and a bathtub full of powdered narcotics. Coming up with a reasonable explanation for that one took some doing, you whore.”

“I said I was sorry.” The Witch sounded none too regretful, but she touched her lips to the husk of Celestia’s horn — an act more intimate, in its own way, than the deepest of deep throats. “I know you want it, too. You don’t have to put up a front with me. Please?”

The Witch was right, of course. Celestia could sense the fresh load percolating in her massive nuts, and precome was already wetting both their chests. But this was still, technically, a working meeting. Priorities had to be set.

“First, I want you to admit my idea was sound,” Celestia said, loving the Witch’s moan of annoyance. “Tell me I was right.”

The ruddy alicorn’s pout was so adorable it made Celestia want to ravage her on the spot. “That remains to be seen. You still don’t understand the danger, Tia. I’d hoped today would’ve been a wake up call.”

The Goddess frowned. “I told you I can handle it. And don’t call me that. I know you do it to get under my skin. Well, it’s working. How about I speak your old name? Would you like that?”

The Witch went silent for a while. “No. No, I wouldn’t. My apologies…Goddess.”

For just a moment, she sounded like she did when they’d first met…a time so long ago, the details of their meeting had become myth. She’d been so young then. So innocent. Time had done its work on them both. Perhaps that was another challenge for the Goddess to overcome…eventually.

“The apology is mine,” Celestia said, slowly working her hoof into the Witch’s soaked cunt to show her sincerity. “I know what you’re trying to tell me. One day my bravado will lead me to my end…but that day has not yet come, I’ll wager.”

After the first successful transfer made it clear that information could pass between the two realities, a plan began to take shape. Like the spies of old, they could send over crafted ideas exchanged with magic to fully destabilize the other world, culminating in the death of that universe’s Celestia. If they could achieve such a thing, victory was assured.

But the theory of equivalence seemed unbreakable. What idea could they send that would not reflect back onto themselves, leading to their own society’s demise?

Celestia herself had come up with the potential solution. They could use her own singular existence to upset the symmetry of the payload. The Goddess’ own mental wavelength would become something like a magical virus, guaranteed to infect the one individual whose emotional signature was unique in every reality.

“You know very well how real the risk is, though.” The Witch’s voice was muffled, since she’d mashed her muzzle firmly against Celestia’s fragrant horsecock. If she couldn’t get a cuntfull of prick right away, she could at least get high on the fumes, it seemed. “You may be much the same in some ways, but your histories will likely be very different. Your fundamental mindset, values, goals, belief system, friends and enemies, lovers…all that will diverge.”

The Witch took a deep whiff of Celestia’s cock, and she moaned as the aroma went straight to her brain. The Goddess felt her lover’s creamy juices gush anew under her hoof, and she found it increasingly difficult to hold herself back. Work, then pleasure. Lots and lots of pleasure.

Vorfreude. What did that word mean, and why had it entered her mind just then?

The Witch muttered something unintelligible. “Use your words,” Celestia chided.

The sunset alicorn pulled her face away from the dizzying cock with a gasp, lustily licking old sweat, semen and marecome from her chops. “Fuck, that’s good. Thankfully, we have more clues about our enemy after the incident this morning. Our target seems…naive in many ways. Kind. Optimistic. She cares very much about her ponies, though her love is very different from yours. She also obsesses over her failures in a way that you don’t.”

“Because I don’t fail,” Celestia said with absolute certainty. It wasn’t a brag. It was just the plain truth…as she saw it.

The Witch pursed her lips, as if holding back something better left unsaid. “Of course. The thing is…she also has the same…hungers that drive every alicorn. Depending on how she’s managed that side of herself, the equivalency could become a problem. You might be walking into-”

“Enough,” Celestia growled, and the Witch immediately went silent. She seemed to know the limits of being bratty.

“Overthinking all this is pointless. I felt her emotions as if they were my own. She is weak, my love. When all is said and done, someone like that is not a conqueror. She would never have been able to achieve what I have, not if she had all the time in the world.”

Celestia’s eyes grew unfocused, as if she could see across dimensions into an unknown realm. “My strength is utterly overpowering, Witch. I imagine my thoughts are already intermingling with hers…changing her from the inside out…affecting her personality in ways she can’t understand. Maybe she doesn’t even realize what’s happening. And in the end, she will destroy herself, beating her brains open upon the rocks of madness…or it will be done to her, by the people she loves most, as she becomes a stranger to them. Either way, our path will be clear.”

The Witch gazed up at Celestia as she spoke, enraptured by the alicorn’s absolute self-confidence. Abruptly, she dragged the Goddess’ face to hers, kissing the other with a sloppy, tongue-filled, spit-soaked fervor.

“There truly is only one of you,” the Witch sighed as she pulled away, affectionately touching her horn to Celestia’s. “Even if there are others with the name elsewhere in the multiverse…there is only one Crowned Sun.”

“And thank the stars for that,” Celestia murmured.

The Witch chuckled. “It’s funny, isn’t it? ‘Thank the stars.’ ‘By the stars.’ You use that phrasing all the time, but your ponies have no idea where it came from.”

“And they never will,” Celestia said with conviction. “The original wielder of those stars is long dead. If not for me, she would be utterly forgotten in time. But as long as I live, I shall keep her memory alive…which means she will live forever. And that is more than enough. Those memories are mine alone.”

The Witch’s pure white horn began to sparkle like a distant jewel. Celestia grunted in surprise as she found herself placed flat on her back, her legs spread and mighty cock a-thrust to match the monument outside.

Her lover straddled the alicorn’s large body with her own, slight form. The Witch rubbed her soaking twat to the slab of knotty horseflesh at her rear, and a burning spark seemed to travel between cock and cunt, demanding a resolution to their seductive play. Both ponies hissed at the shared sensation as a gush of precome showered the two of them in hot fluid.

“Those memories are mine as well.” The Witch gazed down into Celestia’s piercing, jewel-like eyes…perhaps the only part of her that had not changed appreciably over the millennia.

She touched a hoof to the Goddess’ muzzle, silencing her protests. “No. Let me say this. She may have been your lover, but I was her friend, though there was some jealousy, as well. I can admit that. I know I can never take her place…but at least, allow me to soothe your soul.”

“The day my soul is soothed is the day I lose my ambition forever,” Celestia growled. But her fat cock throbbed against the Witch’s ass cheeks, as if in response to the alicorn’s offer, and the Goddess could only chuckle at her body’s honesty. “I suppose you are welcome to try, though.”

The Witch laughed — by the stars, her expression looked so much like hers — as she rose into the air with a flap of wings, planting her drooling cunt firmly atop the flat tip of Celestia’s holy spire. Slowly, never taking her eyes off the Goddess to savor her reactions, that deceptively tight twat began to stretch wide, engulfing the first few inches of her lover’s fat breeder. They both moaned as the scalding orifice convulsed, and silky cunt cream dripped down the prick in rivulets. At the same time, fresh pulses of precome splattered out of the Witch’s fuckhole, and their merged juices made new stains upon the bedsheets.

“You wanted…oh, oh fuck…you wanted my little pussy to stay nice and tight for you, just like the first time, didn’t you? But that’s not what you really need, is it? You need a pony who can take everything you have to give, and ask…beg for more. A pony who won’t break when this big…fucking…cock destroys them from the inside. None of those mind-raped fanatics out there can do that, no matter how much you toy with their DNA. Only I can truly please you, Celestia. Only me.”

As she spoke she slid lower and lower, and they both watched, enraptured, as the massive bulge of Celestia’s cock rose higher into the Witch’s body. The Goddess could not deny the truth of her lover’s words. Her insatiable tool had done things to the lithe little alicorn that would’ve made any other pony recoil in horror. Every hole had been used and abused in a million different ways…and she still came back for more. Thus did the power of magic prove its worth.

“You have an…ahhh…an amusingly high opinion of yourself,” Celestia said, grimacing as the intense contractions around her cock threatened to drive her insane. The Witch was about halfway down already, but that was not nearly enough. The Goddess reached up and took hold of her lover’s hips, stopping for a moment to stroke the cutie mark on her haunch — a white archway, brilliantly cut from a single crystal. Was that mark still affecting the Witch’s destiny, even now? It was one of the oldest mysteries of pony kind, and the answer eluded them to this day.

Well. Ancient enigmas could wait. Celestia’s third load of the day was begging for release from her overactive nuts, and she could sense it would be just as voluminous as the first. Even for her, such an instant refractory period was unusual. Perhaps that was another gift from her unseen doppelgänger. If so, they had more in common than she might have thought.

With a force that would have torn apart a normal pony, the Goddess pulled the Witch’s hips toward her own. The ecstatic screams of her lover as she was filled with cockmeat shook the bedroom, and her slender legs began to twitch as if she’d been electrocuted.

A rush of fluid broke the seal of the Witch’s stuffed cunt to coat Celestia’s dark red knot — if she didn’t know any better, the Goddess would have thought the alicorn had lost control of her bladder. It wouldn’t have been the first time, in any case…by accident, or otherwise. But the silky feel of the juices on her snowy hide combined with an unforgettably piquant aroma told the true story. No pony she had ever been with had been as gushing wet as the Witch, and Celestia loved her for it.

The Goddess was relentless. She drew the Witch down further, heedless of any useless organs in the path of her fat breeder. She could take it, after all. She would take it, all the way down to the…

Celestia stopped…or rather, she was stopped. Something kept her from burying herself entire into the squirming sheath above her. A blockage was there, and the strange mixture of inviting softness and unyielding firmness against the head of her cock made the Goddess roar in anger.

The monochrome mists in the Witch’s eyes whirled in amusement as she watched Celestia rage. With a teasing hoof she prodded the bulging tip of her lover’s prick in her chest, pulsing like a second heartbeat, and she tittered as the Goddess strained for deeper insertion, to no avail.

“Is there a problem, Holy Mistress? You look rather stressed. I’m waiting for you to fuck me into madness, like that other thing you discarded. Can’t you get it all in? Or is the gate of my cervix too well defended for your battering ram to overcome?”

“Let me in!” Celestia’s roar was that of a starving lion as her hips rolled, fighting for one more inch, one more centimeter. “I demand it! You are committing the gravest of sins! I shall cast you into the deepest void for this sacrilege! Open your womb to my cock, little pony. Do it. Now!”

The Witch touched one of Celestia’s hooves desperately gripping a haunch with her own, and she gave the Goddess a challenging grin. The sparkling light of her horn almost overpowered the late morning sunlight.

“Tell me you love me. Say the words, and I will give you what you desire. This tight, hot, sucking womb is waiting for you, Celestia. But it will not be breached without parley. All you have to do is say, ‘I love you, Witch.’ That is all I ask. Is it too much?”

With every word that dripped from those sultry lips Celestia’s wrath increased, along with her unfathomable need. This bitch had chosen the wrong time to play games. The Goddess could now clearly feel the magical barrier preventing her from breaking open her lover’s deepest chamber, and the sheer insolence of its existence made her want to crucify the twisted alicorn. It took all her willpower not to issue the divine command. The Witch would’ve found a way to get off on it, anyway.

Had she forgotten? Had it been so long since Celestia expressed her power that this absolute cunt now thought she could get away with such silly taunts? It seemed a demonstration was in order. Let the Witch remember why the Crowned Sun of New Canterlot no longer needed magic to rule.

The Witch must have felt the change come over Celestia, as the Goddess could feel a new tension in her lover’s body. But it was too late for apologies. Her grip on the Witch’s thighs became like steel.

“Don’t swallow your tongue,” Celestia murmured. She took a deep breath. The muscles in her arms and back all stood out in sharp relief as she mustered her strength. Then, in one fearsome motion, with the power that had built and defended the greatest kingdom in the galaxy, Celestia heaved.

The Goddess savored the Witch’s piercing scream almost as much as the crackling shatter of a spell overcome. Celestia’s cock stretched the smaller alicorn’s chest to an impossible degree as it sank home in the snug womb, and the fluttering cervix seemed to suck on the head of her prick like a second mouth. The orgasms that roiled the Witch’s spasming channel were lover’s kisses, wet and passionate, and a pressure that could have crushed diamonds made the Goddess moan and laugh, all at once.

Celestia recovered her faculties first. She tensed her internal muscles, making her cock flare larger in the Witch’s forced-open cunt. A gibbering wail answered.

“What happened to all that fine talk, little one? Your magic is broken, by mere flesh and blood and strength of will. Come on, then. Defy me again. Play your next move in our game. Or have you conceded defeat already?”

“Bbbblll…urghhh…Celestia…you…how…” Spittle ran down the Witch’s sunset muzzle, and her strange eyes were wide, as if she was experiencing something not meant for mortal minds.

Celestia began to fuck with long, fast strokes, making the Witch’s body flail like a broken doll around her prick. She brought the alicorn’s twitching face to her own as she cored out her insides, close enough to feel the hot, overexcited breath against her own skin. The massive log of cock audibly slurching in and out of the Witch’s womb almost made their tryst a ménage à trois, so large did it loom between them.

But if Celestia had learned anything in her long existence, it was that cock was only a tool. It was her mad passions that had made mares scream her name from here to the edge of the known universe. Even if she’d only had a cunt, she’d have been able to do the same.

Still…a nice, fat prick certainly made things easier.

“You want to know how I broke you?” Celestia’s breath hitched as her own moment of truth crept closer. “If that is your question, then I don’t think you’d understand the answer. But we are not yet done, little pony…oh, no.”

Celestia’s fucking abruptly stopped, instead becoming a steady downward weight. Her fat knot throbbed against the Witch’s straining twat, causing it to admit the bulging invader in a way that should not have been physically possible. But the Goddess had been doing the impossible her entire life.

“You’ve done well taking so much of me, little pony.” Celestia’s voce was hoarse. She was close…very close. “Despite your childish attitude, I suppose you deserve a reward for your…flexibility. Receive this gift of truth from your Goddess, and be thankful.”

She brought her lips to the alicorn’s ear. “I love you, Witch.”

With a pop, Celestia’s full knot entered her lover’s twat. She barely had time to register the Witch’s keening cry — of adoration, tinged with pleasure and relief — before her balls lifted in their soft-furred sack. Her teeth clenched as the power of her coming took her breath away, forcing an ocean of semen into a too-small container. And yet, the Witch’s belly expanded, accepting every ounce of steaming jizz without losing a drop of the precious fluid.

Both ancient alicorns groaned as their mutual release turned them into beasts of sensation…at least, for the moment. Later, there would be much more work to do — there were so many experiments to run, and plans to be drawn up for the conflict to come. But right now, they would enjoy the spoils of their efforts as only the gods themselves could.

Far below the rutting pair, in one of the spacious gardens surrounding Celestia’s tower, a deep gouge could be seen in the soft earth. But of what had marred the formerly immaculate surface, there was no sign.

The next day, a new bed of flowers would be planted in the same spot, erasing any trace of Josephine. The Crowned Sun demanded perfection.

Always.
