"So let me get this straight. You want me-"

Princess Twilight, wearing nothing but black heels and a lab coat, pointed at her bountiful chest.

"To share your cock." She pointed at Sunset's crotch.

"With all of them." She gestured at Sunset's wives.

Sunset grinned sheepishly. "Yes?"

"Hoo boy..."

In the center of Earth Twilight's lab, amongst the various beeps and boops of electronic gadgetry, Princess Twilight sat her ripe, supple ass on the office chair.

Within her bosom, her dark chocolate shaft had snuggled itself comfy, steadily drizzling thick pre. The obstruction posed a challenge to pinching the bridge of her nose in irritation, but she managed.

Fluttershy looked abashed. "Is something wrong?

"No, no. Nothing's wrong." Twilight rolled the chair over to the table, shuffling through her Earthbound counterpart's meticulous - laminated - - notes. "It's just I'd have no idea where to start. I've never done any extensive research into the magic of your geodes, and that's clearly what gave you all your powers and turned you into smoking hot bombshells. Usually, in Equestria, I'd start with some simple body modification spells, some intermediary transference matrices, and we'd be off to the races. Sun, I bet I could just as easily slap some constructed cocks on you and you'd have the equipment you want. Except..."

Sunset finished for her. "We don't just need the equipment. We need full functionality."

In other words - the ability to impregnate.

Twilight groaned, head in her hands. "Correct."

Warily, Sunset approached, placing a tentative hand to her shoulder. "Look at it this way, Twi. You've got a whole new problem to solve."

As of late, Princess Twilight had solved many such problems. Born from her inquisitive nature, in the times she'd come and gone through the mirror, she had begun unraveling yarn by yarn the minute and major differences between their two worlds' magic. For her, solving problems was where she found her fun.

It wasn't the only 'fun' that she got from it, though. Through careful study and research, she had been able to replicate and display her true hybrid form.

Nowadays, she and Sunset stood eye to eye. The only real difference lay in their physique - Twilight more supermodel, Sunset more superwrestler, though equal in feminine sex appeal.

Yet between the two, Sunset possessed the greater magical knowledge. Things worked differently on Earth than Equestria. The root magic may have been the same, but Sunset's personal experience and exposure gave her a greater wealth of reference to work from.

As of late, that had begun to change.

Every day, the differences grew smaller. Every day, with increasing frequency and intensity, Equestrian magic bled into their realm. Perhaps not so fast to bring their worlds' thaumic tapestries in sync any time soon, but a full shift was nonetheless inevitable. It was a plain, simple, irrefutable fact. They'd need to look into cutting the flow soon, or chaos would reign.

Twilight met her gaze, and with a smile eased her hand aside. "Thanks, Sunset. You know how I can spiral."

Sunset could not help but snort, eyeing her wife of the same name. "That I most definitely do."

"Okay!" With a start, Twilight launched herself from the chair. Clacking heelstrides brought her over to her other self in a second, whom she grabbed by the wrist and pulled close. Their buxom chests squished delightsomely together. "Me, it's magic time."

Wife Hybrid Twilight crossed her arms, pushing up her breasts. "Excuse me. It is just as much magic as it is science."

Placing her hands upon her wide, doorframe-brushing hips, Not-Wife Equestrian Twilight scoffed. "Magic and science exist on both sides of the portal, so there's no reason to say either field belongs to one or the other. And, depending on the pony you ask, the field of magical studies is just as scientific as any other discipline. Not to mention that, if anything, given magic originates from my world - where we also have science - you could make the argument that magic and science are actually both pony-"

Sunset tuned out. She knew Sparkle dissertations when she heard them, and the only thing worse than a Sparkle dissertation was a Sparkle debate.

Even worse. A Sparkle on Sparkle debate.

Sunset shuddered.

Sunset observed from a purely visual perspective her wife flush, stamp her foot, and twitch her lavender ears in adorable frustration. Less adorable, more dick-hardening, was the salacious series of jiggling that cute little foot stamp set about.

As the two intellectual terrors raged on, Sunset's attention flicked between them. It struck her suddenly that it might be wise to properly name the two in her mind. Thinking of them both as 'Twilight' got a little head-spinny after a while.

At first, she was tempted to name her wife Sci-Twi. Sci for science, and Twi for, well. Duh.

But that felt wrong. While yes, Princess Twilight had been the first of them she'd known, the Twilight Sparkle who came from Crystal Prep, whom she saved from the madness of Midnight, was her wife. Giving her the nickname between them just wasn't right.

So, in that case. What to call Princess Twilight?

Magi-Twi, for magic?

No, too long. Equi-Twi, for equine?

Same problem. Also, honestly? Just sounded kinda weird.

Or what about Pri-Twi? For Princess-

No. No. No. Absolutely not. Heavens to Celly, Sunset, that's the worst one yet. How could you even consider that?

"Aha!" She snapped her fingers. "Got it!"

The gaze of two very confused Twilights fell upon her.

She returned an awkward grin. "Was just trying to think back on where I left my onahole. Just remembered. You may continue." She waved a hand.

Hopefully the lie was of sufficiently embarrassing quality. They had to buy it.

They looked at her a moment longer, amethyst eyes narrowed in analytical suspicion, before resuming their dialogue.

Sunset relaxed. Thank the Sun she didn't have to explain what she'd actually been thinking about. That was way more embarrassing than her 'forgetting an onahole'.

Nevermind she didn't actually have one.

Yet.

She'd considered buying one for herself as her own personal Christmas present. Y'know, when her wives weren't available. Or she just really, really had to nut in a tight fucking pocket pussy.

As for her naming scheme? Twi for Princesss Twilight, and simply 'Twilight' for her wife. It was beautiful. Elegant. Truly, only the mind of a great genius such as herself could conjure such a magnificent solution.

"Hey Sunset?"

"Huh? Whuh? What's going on?"

Twi tapped a pen to her cliboard. "Twilight and I are going to run a few tests to get started, but we need you present. Is that fine?"

Sunset glanced to her wives, then the Twilights, then nodded. "Cool with me."

"Great!" Twi clapped her hands before politely shooing the rest out. "Sorry, but we need to keep the study sample small for this one. Magic can be a bit volatile, and it's better to isolate our variables."

"Ugh, okay, we get it," Rainbow groaned. "Just... please, stop talking like a nerd."

Twilight and Twi shoved her out the door, with Twilight delivering a smack to her fit ass. "Never gonna happen, sweetie."

The door clicked shut. Seconds later The two Twilights stripped completely down, and Twi pressed her busty self against Sunset's front. Her sheath throbbed in her jeans, and each heartbeat brought a growing, hardening pulse behind her zipper.

"Woah there, cowgirl. Aren't we supposed to do research?"

Twi licked her lips, grinding her ebony shaft between Sunset's tits. "This is research. See?"

She pointed behind her. Twilight had plopped herself in the chair, legs spread and puffy violet mound on display, standing in stark contrast to her silky flesh. Fingers teased apart the folds, rubbing her winking bead as papers, pens, and recording instruments hovered beside her.

"She's, mmm, right," Twilight moaned. "Studying sex magic requires, hahhh, intimate means of conduct."

Sunset had doubts. "I want to express my concerns, but I also don't want to say no."

Twi leaned in, breath hot and balmy. "Then don't," she whispered, before their full lips pressed together.

Sunset did not resist as Twi slipped her tongue inside. For moments they warred, moaning and groping their twisting bodies. Their tall, spiralling horns clicked and slid against one another, creating in Sunset's skull a pleasant, dull tingle that led down to her loins.

When Twi pulled back, lust in her eyes, Sunset looked down to discover herself entirely nude. Off by the wayside, her clothes sat in a neat and folded pile, pressed so immaculately it would make Rarity impressed.

"Fuck." Sunset gasped as her shaft pressed against Twi's. Two equine pillars of throbbing, stiff flesh. One like mottled caramel, the other smooth dark chocolate, and both rapidly rising. Pre oozed from their tips like leaky faucets, smearing and staining the skin slick and sticky. "You... have got to teach me a spell like that, mmmmph. I-it'd make handling our daughters' laundry so much... easierrrrr!"

Sunset shut her eyes, rocking into Twi. Their hips ground together, turgid staffs of thick, virile maremeat grinding and grating the veins, the medial rings, their sensitive undersides.

"S-shhhit, Twi. I, ahhhh- always thought frotting was one of those things you only see in porn, but this..."

"Feels good?" Twi giggled. "I was surprised too. Now grind harder, babe. I really gotta test this theory..."

Sunset didn't bother asking more. Twilight occupied herself recording some kind of information, whatever that was beyond two giant horny horse women frotting with their arm-long equine fucksticks. She could worry about the science part.

Twi and Sunset could worry about the sex.

And oh by Celestia's glorious flanks did they.

Some 69ing, piledrivers, full nelsons, reach-arounds, spitroasts, and prostate milking later, they had the data both Twilights said they required. In grand total, it came up to a full twenty-four hours of shameless, frantic, and frenzied rutting.

They certainly had the results to show for it. One in the form of whole paper-stuffed manilas. The other - a very, very sticky lab, permanently stained with the scent of cum.

Sunset wiped the sweat off her brow, extracting herself from the snug, wall-mounted fleshlight. One now thoroughly glued shut with no less than a pint of steaming, maple-thick horse jizz. She fought the urge to plunge in just one more time, feel her own sloppy spunk warming her cock.

"That the last sample you need?"

Both Twilights nodded, one bouncing on the other's lap.

"S-s-should be everything!" Twilight said, though it was hard to hear her over her own squealing, cunt gushing, hips slapping, and Twi's grunting. As Sunset eyed them Twi picked up the pace, firmly grasping her smaller self's lovehandles and turning her girthy shaft into a hole-gaping jackhammer.

"Ohhhhhffffuuuuuuck!"

Sunset arched a brow. "So is there any reason you're doing that or..."

Twi grinned. "Nope! I just think your wife is super hot."

Despite her screaming orgasm, Twilight managed to blush.

"You do realize she looks basically exactly like you, right?"

"Are you telling me you wouldn't tap your human counterpart?"

"...Okay. Fair."

"And there's your one fatal mistake, Shimsham. You. Ha! Don't. Ha! Debate. Ha! MmmnnMe!"

Twi screwed her eyes shut, nostrils flaring as her heavy equine orbs drew up. Sunset heard the cum travel up her pipe, saw it turn Twilight's slim waist into the mildest paunch. Oodles and more of slimy porridge drooled through the marecunt seal, pooling in the crease of Twi's sack, as she continued to fuck and thrust through the ride.

Gradually, panting, she came down from the peak. Her lips offered a toothy grin, one eye opened, and in it Sunset saw a perverted twinkle.

"You can join if you want," she crooned. "I'd like to run another experiment, just for us." Her grin widened. "How about we see if two cocks can fit in the same hole?"

Twilight sputtered. "W-w-wait what?"

Already on it, Sunset pressed her flare to Twilight's entrance. "Yeah. I fuck with that."

She slipped in, drawing a laughing moan from the alicorn. "Literally."

For the next month, Sunset and her wives barely saw hide nor hair of either Twilight.

On occasion, Twi did come back and forth through the portal - one they'd since moved from the statue to their house. For the most part, however, she'd instructed Spike and Starlight to hold the fort. Any emergencies or Princess demands that drew her back, she ushered along as quickly as possible.

Sunset would admit. She was surprised.

In the past, Twi never seemed keen to linger long this side. Sunset wondered if it might be the selfcestuous siren's call of her own counterpart's fat, meaty horse pussy, but she doubted it.

Twi had seven such fat, meaty horse pussies back home, ready to serve up at her beck and call. If what Sunset gathered from an off hand comment was heard right, that offer extended to many from Ponyville's prime breeding population as well.

Sunset was mare enough to say she envied Twi. She savored the thought of strolling down the street, cock out and throbbing, with hot ass mares flicking their tails aside and presenting their wet, drooling gifts just for her. Shamefully, she'd spent many a self-love session pumping said cock to the fantasy of that cultist from November.

Alas. She only had six wonderful, beautiful, amazing wives. Woe was her.

As for the Twilights' absence, she could imagine one compelling reason if they shared deeper similarities. On many occasions, Sunset remembered well how Twilight would find some new scientific question to solve, and throw herself endlessly against it until she had her answer.

Despite her seclusion, Twi did still crawl from the hermit shack every few days. In those short breaks, it gladdened Sunset to see she got on well with the kids.

The first time they saw her, they were awestruck. The sight of both Twilights side by side then prompted Amber to start cheering "Two moms! Two moms!" until all nine troublemakers were running and chanting the phrase through the whole house.

Before Rainbow promptly - snarkily - reminded them they had seven.

But while the lab seemed to have become the pair's current home, Twilight continued coming to bed. To that, Sunset was thankful.

She would have sorely missed any one of her mare's absence. Twilight especially, however, given their history, all that they'd been through.

Several times, Sunset and her mares expressed that Twi was more than welcome to sleep in their bed if she so wanted. Generally, she did not. Once or twice she did oblige, though only as a means of partaking in a bout of frisky business.

Sunset couldn't begrudge her for that. Twi had her own herd, her own wives back home. She liked Sunset and the others as friends - Sunset a particularly close one and Twilight as a respected colleague - but nothing more, and that was entirely fair.

Fortunately, the home offered plenty spare guest rooms for dozing off. They went seldom used. Most cases, Sunset would travel down to the lab with breakfast in tow or simply to check on progress, only to find the mare passed out in an office chair, snoring and drooling against a table.

Sunset liked to use the highly academic term 'quite frankly, hella cute'.

Not that she'd tell her that. Sunset got the inclination informing an alicorn they were 'hella cute' for drooling on themselves in their sleep would be something of a kick to the ego. And, as someone who liked her ego exactly the way it was - give or take some generous strokes - Sunset refrained from letting that comment slip.

December passed without much fanfare, beyond the usual holiday ruckus. Sunset was just glad they had seven incomes to split amongst buying gifts for their nine children. Meanwhile she, herself, did in fact buy that onahole.

It was a slow January morning. Their kids had gone off to school hours ago, taken by the bus. The sky shone a dreary, bluish gray. She and her wives, sans Twilight, spent their New Years' vacation time together in the living room, watching some show or another. It was boring, but it was the kind of boring that lulled you into its boringness, until you were left so devoid of care you nor anyone else bothered switching it off.

That was until Twi and Twilight burst from the downwards stairwell door, buzzing with excitement. Their words rambled off, trampling over one another, to the point of incomprehensibility. AJ had to step in, calm them both down, and get them breathing normally. Eventually, they managed to speak without tripping over their own tongues.

"We've done it," Twi exclaimed. "It's connected to your geodes. I just knew that was it!"

"They're a very powerful artifact. Twilight says they remind her of these 'Elements of Harmony', but she doesn't know why there's a seventh in our case."

"Mhm. Still gotta figure out that one - and a lot more about them in general. To tell the truth, I'm not even a hundred percent sure these geodes are Equestrian in origin at all, or if they are they are very, very old. Old enough I wouldn't recognize the arcane signature as any currently known form of magic."

"T'would make sense if that were the case. That Memory Stone and Time Turner er whatever Sunset called it weren't from yer time neither."

Twi shrugged. "I can't say." She brought her hands together, squealing. "Not that it's important right now! The point is, I know how to get you knocked up, Sunset! Aren't you excited?!"

"I, uh. Heh." Sunset laughed, scratching the back of her head. "Yeah. A little nervous, admittedly."

Twilight walked up, standing on her tiptoes to kiss Sunset's cheek. "You will be, but it's okay. I survived, and I'm not some crazy immortal alicorn like you are."

'I'm not some crazy immortal alicorn like you are.'

The sentence entered her mind. It ping-ponged off the walls of her skull, growing louder and fuzzier with each repetition.

She forced a smile and kissed Twilight back. "Thanks, baby."

"Let's get this done then, shall we?" Twi chirped, extracting a palm-sized notebook from her coats' pocket. "Whether or not this works, I've got notes I want to take."

Fluttershy frowned. "You don't know if it will work?"

Twi rolled her eyes. "Of course not. You can never know for sure if a new spell is going to work, just like you can't know if a new medicine will. You have to run a trial, see if there's any side effects. Speaking of which, does everyone here consent to the study? I highly doubt there will be any complications, but there is a teeny tiny risk something goes wrong."

"What're the odds?" asked AJ.

"Yeah," Rainbow echoed. "I prefer to bet on money, not my body."

"From our calculations," said Twilight. "There is approximately a point oh oh-"

"Okay, okay! It's low, we get it. No more numbers, please. That show already melted my brain."

Both Twilights giggled.

"She really is the same in every universe, isn't she?" Twi said.

"What's that supposed to mean?"

Sunset arched a brow, crossing her arms. "Hold up. 'Every' universe. There are others?"

Twi blushed. "Oh! Oh, sorry, haha. Misunderstanding. I've only been to this one. I just meant, y'know-" She gestured vaguely.

Twilight turned, placing her hand on the stairwell bannister. "Before we begin, I need to go downstairs and retrieve the equipment. Twilight will tell you what you need to know. She's better at the magic thing than me."

"Not forever you won't be! Definitely not if this past month's performance is anything to go by."

Twilight hid behind her bangs. "Yeah, well. Helps I've technically been studying it since highschool."

Twi huffed. "Don't sell yourself short, Twilight. You're smart and we both know it."

Before she could get in another word edge-wise, Twilight squeaked and scrambled down the stairs.

Leaning an arm against the couch, Rarity sipped wine from a glass. "That girl needs some serious pep talk."

"You're tellin' me," Rainbow muttered.

"Either way! Let's get this done." Twi strode to the front door, throwing it open. A gust of cool winter air whooshed into the building. "Everyone, outside. I'd like to minimize whatever damage might occur if things go wrong."

Sunset took the first step, the rest following her lead. Outside they were greeted to pale-green grass waving in the wind, the sky above an icy, cloudless expanse. While the surrounding forest of apple trees remained hardy, strong as oak as ever, others fared less fortunate in the face of winter's chill.

Twi quickly caught up, stopping some ways away. Squatting, she pulled a small red flag from her coat pocket, jammed it firm into the earth, and straightened. "Here should work. Trees and the house are far enough away. Oh, another thing I forgot to ask. Do any of you know how far we are from the city?"

AJ's brows furrowed. "'Bout two'na half miles. Why?"

"Oh, nothing serious. There just might end up being an EMP discharge from the spell, and I'd rather not black out any civil infrastructure."

Rarity raised a hand. "May I interject?"

"Go on."

"To be entirely forthcoming, some of your statements have not filled me with the greatest ease. Are you and Twilight certain this is safe?"

"No more than the scientists who worked on the atomic bomb."

Twilight, levitating many large metal boxes behind her, strolled in. They all - save Twi - watched curiously as she set them down, one by one with careful scrutiny. When she was done, Rarity quirked her brow, folding her arms and pushing up ample pounds of milky cleavage.

"I'm not quite certain I catch the reference, darling."

"Did you never see Cloppenheimer?" asked Rainbow.

"I don't even know what that is."

Twilight rolled her eyes. "It's a movie, about the man behind the Manehattan Project. Before they tested the nuclear bomb for the first time, he and his team estimated a fractiously small but existent chance the explosion might never end, continuing on until it engulfed the world."

Rarity gasped, hand to her mouth. "And they carried through with it, despite the knowledge?"

"The estimate was something along the lines of zero point zero zero zero three percent. In other words, technically possible, but profoundly improbable."

"That's roughly what we've calculated things down to as well," echoed Twi. "You really have nothing to worry about. I've been training Twilight on Equestrian theorems since we started, and she's been teaching me how magic works here, so we really should have no issue. The risk comes more from the spell circles than our individual spellcasts anyway."

Meekly, Fluttershy spoke up. "What are spellcircles?"

"Pretty much what they sound like. You draw runes and patterns on a surface, in a circle. Those runes and patterns act like words or sentences, and if you pair them together in the right order, they form a complex spell, kind of like a paragraph. They're useful for more... complicated things like this."

Sunset nodded, adding on. "Here on Earth, lots of occult magic talks about them. Witchcraft and older pagan stuff. I've never seen any evidence they work, though."

"Mhm. Probably because magic isn't as natural here as it is in Equestria. That, or they're not using the correct runes. A spellcircle won't work if what you write down is complete gibberish."

"COuld be both," Twilight offered.

"Either way, I think that's enough lecturing for now. You girls want dicks. Sunset wants babies. I wanna make that happen. But first, I'd like you all to step back. We need to set up some equipment. If anyone wants to help they can. Strength and magic is going to be the biggest help."

"Oh," Twilight added. "And accuracy."

"Yes, and accuracy."

Fluttershy, Rainbow, and Pinkie stepped back. AJ, Rarity, and Sunset moved forward.

In unison, the two Twilights worked together, opening boxes. They gave instructions, and Sunset and Applejack helped haul out and plonk down the heaviest equipment. Rarity and Sunset with their magic tuned switches and dials to the Twilights' request.

When they were done, all sorts of technological gizmos faced them in a kind of widespread u-shape. Sunset didn't recognize much of it, but she did some. At four points stood tall, lamp-like structures, topped with what seemed to be artificer's clasps. Between the three pronged heads, thin arcs of magenta lightning spat between them, creating a quiet, pervascent hum. Two focusing irises pointed inwards, their roaming eyes aimless without a target.

Sunset whistled. "You weren't kidding when you said this was complicated."

Twi grinned. "No I was not, and we haven't even drawn the runes yet. Twilight, you have the diagrams?"

"Sure do." Twilight opened her coat, retrieving a sheath of papers. They lifted up into the air through magic, and stayed floating, facing towards them. "I don't know the runes like you do, so it might be better for me to step back on this one."

Twi gave a nod. "Sunset, what about you? Did you ever practice much rune-carving."

Sunset wavered a hand. "It's been a long time, though. But if you need my help, I can try."

"Come here, then. We have the diagrams anyway. Just feed your magic in as you're going. This spell is going to need some real oomf."

Beside her, Sunset and Twi got to work. Slim beams of teal and magenta magic poured forth from their horns, and slowly but surely engraved intricate patterns into the ground. At first they'd glow with their initial magical input, but as time went on the opposing colors merged to form a shimmering, iridescent lilac.

The design contained three circles. Not spread out, each had in itself another, smaller. They began with the largest, some twelve feet across, the sides of which nearly brushed the equipment. From there they worked clockwise and counter respectively, until culminating at the last and smallest circl a third the original's size.

Sunset leaned back, wiping her brow. "I have almost no idea what any of these runes mean, but that took a lot outta me. You don't need my magic for the main spell cast right? It's been a long time since I've really done actual Equestrian magic."

"Don't worry. Me and Twilight will handle that."

"Twilight and I," Twilight corrected. Twi huffed. Sunset smirked.

"First," Twi said. "Everyone get in the circle. You don't need to stand anywhere particular, just make sure you're inside. Also, strip down. I don't think you guys want your underwear getting ripped in half."

They did as she said, shuffling into the space. With seven distinct amazonian figures, it crowded quickly, elbows brushing waists with fat mark-stamped booties and boobies squish-squashing every which way. Any mild winter chill that might otherwise have existed never stood a chance.

Twi inhaled. "Alright. Here I go. Follow my lead, Twilight."

Her horn lit magenta, joined by Twilight's. Orbs of arcane energy appeared at the spire's point, growing and swirling with a dazzling array of streaks and sparks. Twilight's wavered as it grew, partially unstable, but the moment their spells connected it settled.

Gradually, the two orbs became one. Sunset observed in a mixture of fascination and wonder. She'd seen magical collectivizing here and there in her time with Princess Celestia, but only on the small scale. Watching this made her feel like she was watching two stars collide, glowing masses of energy feeding back into one another until something stable somehow formed.

The spheres' edge crept closer and closer. Both Twilights' hair blew in unseen wind, and the air itself seemed to spark around them, as though vaguely electrified. The edges were right there, one blink away from kissing, completing the spell.

Then, the world went white.

It stretched on ad infitum. She tried calling out, or raising her hand in front of her face to see.

Her mind went back to her transformation into Daydream, or the form she took today. Those had been similar to this, but shorter lasting, the blast of white light similar to a momentary flash.

As she strained to hear anything beyond the nothing - not even ringing - she began to make out sounds.

Familiar sounds.

Schlap, fap, plap, whap, slap!

"Unnnngghhhh!"

"Yeah, that's it. Fuckin' take it you bubble-assed siren bitch!"

"Annnh, Daddyyyyyy~"

Sunset knew those voices. Both of them.

Because one was her own.

The vision of herself breeding a half-fish Sonata Dusk from behind lasted all of a second. Yet in that second she got all the information she'd ever need and more.

Her half-crouched, plowing the drooling Dazzling from behind. Sonata's torpedo tits, more massive than even Fluttershy's, pooled against the floor. Her face stretched into orgasmic joy, with serpentine pupils, serrated shark teeth, a long tapered tongue, and fins in combination with blue equine ears. Shining blue scales decorated her peachy complexion, and she dug sharp claws into the ground as her muscular fish's tail coiled around Sunset's waist.

Above her yoga ball breasts, Sunset recognized a familiar gemstone. It hung not on a pendant, but was embedded into the skin, much like Sunset and her wives' geodes. It had changed color, however, glowing a hot and lustful pink, rather than its previous violent red.

Then, as though with a snap of fingers, the scene disappeared.

Sound, sensation, and structure returned to her all at once, flooding the previous void. She blinked, recognizing the blue sky, the apple trees, her villa-esque mansion only a five-minute walk away.

Five minutes relative to her stride length, anyway.

She looked around to her mares. Their gazes flicked back and forth, a couple rubbing their heads. Had they gone through something similar?

She dearly prayed they had not seen what she had. The visions had established a clear pattern, but with nothing else to go by there was no point worrying or concerning anyone else but herself.

Now that their survival had been confirmed, their was something important to check. Something long, hard, thick, flared, and throbbing between their luscious thighs.

A big, toothy grin spread across her face as she saw them. Fat, meaty slabs of equine girldick. One after the other saluted their attention, drooling tiny rivers of clear pre.

Some matched their skin color, like Pinkie's. Others matched their darker nipples, like Twilight or Rainbow. Applejack's was a mix of mottled tans, Fluttershy's pink and caramel. Rarity's shocked her the most, a mottled pink and dark gray, almost black sheath and balls, which stood starkly out against her pale white skin.

They were a fair bit smaller than her own, a little over half the length she lugged around. If she had to guess, she'd throw her lot in with fourteen, maybe fifteen inches.

Curious, she looked down to her own crotch.

And frowned.

Gone was her mighty, hole-splitting cannon of pony fuckflesh. In its place, another endowment of adequate proportion, the same as her wives.

She sighed. Oh well. Guess she couldn't have everything. Not like this would be permanent anyway.

She hoped.

Sunset tore her gaze away to the sound of two absolute nerds squealing and clapping in their poorly contained glee.

"I can't believe that worked!" Twilight cheered.

Fluttershy arched a brow, expression flat. "I thought you said the chance of failure was low."

"I did, and that was true. I still can't believe we pulled it off!"

"You pulled it off," Twi corrected. "I did most of the prepwork. The actual mana I needed for spellcasting was nothing, honestly. The hardest work was all you."

Twilight huffed, booping her counterpart's nose. "We pulled it off. You said I shouldn't underestimate my abilities? That goes for you, too."

Sunset interrupted, raising a hand. "I don't mean to intrude, but I've got a question." They waited. "How long does this spell last? Because I am not gonna be satisfied with this." She pointed at her crotch. "Forever."

Twilight adjusted her glasses. "The spell lasts until we cancel it."

"Which will be a simple matter," added Twi. "No spellcircles or equipment or anything. Just a good old fashioned spell canceller. I'll need your help with that one, though. Removing something as big as this requires a lot of energy I'm not sure even I possess on my own."

Sunset nodded, uncrossing her arms. Her cock and pussy ached, balls brimming with seed, and she was eager to get things going.

"Also," she said, biting her lip. "Not that I want to rush anyone, but I'm really - like, really fucking horny. You mind if we get started already?"

"Right here, on the grass?" Pinkie chirped. "Freaky~ I like it."

Fluttershy tentatively reached down, touched her flare, and gasped as it twitched. "M-mmm. W-we can breed like real horses." A dark cherry blush overtook her olive complexion, and by the way she pressed her knees together Sunset knew she was grinding her pussy, even if it weren't for the swiftly trailing sounds of squelching.

Note to self. Fluttershy likes horse play.

This is highly relevant future information, Sunset. Good job.

Twi saluted, flaring her wings. Beating them, she lifted off the ground and hovered in place. "I'll leave you girls to it. If you need anything, I'll be in the lab."

Flashing a thumbs up, Sunset watched as she began to fly back.

Fluttershy called out, cupping her hands around her mouth. "Could you keep an eye out for the kids? They'll be coming home from school in a few hours!"

"Can do!"

And just like that, they were alone.

Sunset had prepared to grab her nearest wife, pull her down, and get down to work.

She never got the chance.

The moment Twi turned away Applejack pulled her in from one side. Rarity magnetized to her other, grinding her stiff horsecock against Sunset's supple sun-marked asscheek.

"Fuck, darling," she growled, as AJ forced her tongue down Sunset's throat. Both their cocks touched, rubbing and grinding together, and eliciting happy moans. "How do you ever deal with this thing? It makes me so. Fucking. Horny."

Sunset couldn't get a word in edge-wise. The others, in seeming agreement with Rarity, explored her body with all their hands. Pinching, rubbing, stroking, tracing. With a great heaving shove, six pairs of arms pushed her down, prone against the grassy earth.

Her cock stood at attention, but it was what lay beneath it they were after.

"No, I wanna breed her first!" shouted Pinkie.

"I helped with the spell, it should be me!"

"I can fuck and cum inside her the fastest, then you guys can get your turn!"

"Oh of course, Rainbow dear, as if you won't continue pounding her cunt for the next four hours regardless."

"Not ta mention you'll jackhammer her stupid. Ah wanna hear her mewl mah name while ah'm pumpin' her full 'a babies."

"Oh screw this." Fluttershy stepped in, shoving the bickering studs aside. She bore a wicked grin looking down at Sunset, who had only a moment to fear the inevitable before it happened.

"Today," she purred, rubbing her tongue across plump, pillowy lips that so many times had drained her cock dry. "I get to be the Daddy~"

She was on her in a second. One moment, Sunset wasn't in a ruthless mating press. The next, she was.

There wasn't any fanfare. Fluttershy didn't bother extending her that grace. She simply knelt down in a squat, grabbed her ankles, pulled her legs apart, brushed her balls aside, and thrust home.

Sunset moaned. Not something low and guttural as she usually did. High, girly, the sound of a bitch profoundly deep in the throes of estrus.

Fuck, Sun yes, she needed this.

She wasn't sure if she thought that or said it aloud. It didn't matter for long.

Her other mares - studs, for the time being - homed in around her. Applejack gleefully stuffed her cock right down Sunset's open, vulnerable throat. She choked and gagged, never having practiced oral before, but her amazonian size and alicorn resilience kept her going. When Pinkie and Rainbow knelt beside her she didn't need to be told what to do, taking their presented dicks in hand and jerking them off. Rarity, patient and ladylike as ever, mercilessly beat her meat with the broad pink flare pointed at Sunset's heaving tits.

It felt so fucking good.

She fell into the rhythm shockingly fast. She moaned like a whore around AJ's cock, slurping and suckling for all she was worth while Fluttershy bred her silly. Their hips pistoned together, Sunset bucking up as Fluttershy did down. Her overwhelming, mareish urge to bear life had never been stronger.

She couldn't wait to be pregnant.

Big round belly. Fatter, leakier, milky tits. Her studs could drink from her nipples while they fucked her cunt from below, and she'd blow her steamy fucking loads all over her stomach.

Speaking of which.

Her shaft throbbed painfully, balls clenching, and ropes of hot gooey foalbatter shot across her abs, splashing the underside of her tits. She groaned louder, stroked faster, clenched her spasming twat down on Daddy's dick.

Babies. Babies. Babies. She needed babies.

She came again, eyes rolling into her skull. At the same time Fluttershy gave a distinctly equine whinny, slamming home and burying herself down to the base. Her leathery horse balls whapped against Sunset's bubbly butt, and cups of frothing, virile seed poured like molten metal into her aching crucible.

'Foal factory', she thought. 'I'm just a dumb, slutty foal factory.'

Her eyes crossed, and face pulled into an idiotic, dopey grin. As much as she could manage around Applejack's stiff she-dick.

Was this what her mares felt like when she bred them? Was it like that the first time, or all the time?

Like a dream, she recalled the various times she'd plowed her wives after that first three weeks of rutting. How they shrieked and screeched to put babies in her. Knock them up, make them her worthless, dumbfuck babymaking horse whores.

She thought about AJ pulling out, and leaving her to speak openly. She wanted to scream the same things.

She came again, cock and cunt at the same time. She didn't care how much of her own jizz was coating her face and hair. She loved this. She was born for this. Bred for it. Next time she saw Celestia she ought to thank her, preferrably in the form of taking her royal solar scepter in her cunt.

Sunset had always wanted to call her Mom.

Her last load mixed in with the spunk that followed. Jets shot out from Pinkie and Rainbow, slimy cream getting all over her. On her hands too, bubbly warmth sticking between her fingers, greasing up her palms. Rarity wasn't far behind, painting every inch of caramel skin she could with fashionista fuckslop.

When Fluttershy pulled out, extracting her schlong with a sloppy wet sucking noise, she wiped her cum-coated shaft against Sunset's face. "Eat up, bitch."

Sunset was pretty sure her pussy squirted again. Hard to tell when it blended together.

Twilight stuck herself in after. She got up close and personal, squishing their tits together, lapping up the mixed loads and nipping her skin.

Gosh, Sunset loved her. She loved all her wives, but Twilight had always been the most affectionate and outwards with her sentiments.

If she weren't getting gangbanged by five other marestuds, they'd probably be hugging and kissing. As it was, they made do grinding, bucking, and nickering like farm animals.

Finally, Applejack arrived. Sunset greedily swallowed down every drop, guzzling the thick, salty goodness that creampied her mouth. Nothing but a cum reseptacle for hung she-studs.

Twilight swelled her womb another size larger, and they switched again. Rainbow fucked her next, and it was all she could do not to pass out. She couldn't even distinguish one thrust from the next; they all blurred together into an endless electric ecstasy.

Pinkie swabbed her throat. The others jerked themselves off, coating the grass, each other, and primarily Sunset in their combined love.

It went on for hours, she was pretty sure. The blue sky turning pink, then orange, then red was probably an accurate indicator, or so she assumed.

She wished it could have gone on forever, but Twilight was the first one to stop. She panted hard and heavy, drool dripping from an open mouth and lolling tongue. By now, each of her studs were half as whitewashed as her.

"We... should probably... stop..." She gasped for breath between words. "But I gotta cum one more time."

She slammed balls deep inside Sunset's throat, and as if on trigger unloaded her cargo straight to Sunset's thoroughly swollen tummy. She already looked a month pregnant. The seed that couldn't fit simply soaked the ground.

Satisfied, she extracted herself again with a shuddering groan. "K-kids... are gonna be home soon. We have to wash up."

The rest gave a disappointed nod. They did make sure to blow one last wad on her, though. Her reward for being an obedient fuckpet.

Sunset grinned stupidly, pupils dilated, fingers bearing v-signs. Barely any of her original colors were visible under the sheets of wet plaster. It stuck to her tongue, the roof of her mouth. She didn't even realize she hadn't swallowed the rest of Twilight's spooge until she tried to say something, only to gargle the pool of hot, viscous she-nut.

Gulp~

"Thank you for breeding your dumb whore," was all she managed to say, before fading into the warm embrace of unconsciousness.

She woke later in their large, shared shower. The tiled room had been built to house all of them, many nozzles from above raining down hot water. The space filled with steam, the naked bodies of her stud-wives, and moans.

Everypony had paired off in some variety. Applejack and Fluttershy had their cocks buried in Pinkie's snatch. Rainbow was busy pounding Twilight from behind, pressing her tits and twitching chocolate cock against the wall. Rarity, meanwhile, was in the process of plunging her tool inside Sunset, who had been awake for all of a second.

"Oh hello, darling." She gazed down with a loving smile and sparkling sapphire eyes, wet purple hair draped across her flawless ivory skin. Her pelvis collided with Sunset's, and she lasted all of a few grunting seconds before crooning through her orgasmic load.

The moment the others noticed she was awake, they ran another lewd, loud, sloppy train on her mouth and pussy. The more adventurous and naughty flicked her scarlet-gold tail aside to expose her dark winking ponut, slipping inside the ultra-tight passage and nutting within moments.

Through the deafening noise of showerfall, husky cries, wet shlicks and schlaps, and Sunset's eager cocksucking, they explained what had transpired since she fell asleep. Twilight - pony Twilight, she forgot to use her nickname given her current predicament - had flown back seconds after their orgy concluded. The bus had arrived to drop their daughters off, and she rushed to get them inside as quickly as possible.

Once in the shower, Twilight - wife Twilight, this time - locked the door with her magic. It took barely a heartbeat before they leapt on one another, kissing and grinding and fucking and breeding foals into one another's wombs every which way. Of course, as Rarity had demonstrated, they also took their turns on her sleeping form. Rainbow added teasingly, as she pistoned in and out of Sunset's throat, that she had the same idiot grin on her face the whole time. The humiliation of that fact earned a generous cumshot from her pulsing rod.

Finally, they managed to finish up without wasting another several hours mindlessly rutting their brains out. Luckily, even if they did, Twi would be there to look after their fillies.

They used a lot of soap that night.

Dressed in their least revealing bedtime clothes, they packed into the living room. Twi had found a whiteboard from somewhere, and was in the middle of a lecture on Equestrian magic. Half their daughters looked bored out of their minds. three were actually asleep, which left only two who were genuinely interested in what Twi had to say. Sunset was proud to say Amber was among them.

"Ah, there your mothers are." Twi clapped, startling the slumbering three to awakeness.

"Finally," Pepper mumbled.

Twi shooed them off with a great beat of her lavender wings, Sunset and her wives hurrying along the rest.

Fluttershy knelt, looking them in the eye. "Why don't you girls get yourselves to bed, hm? Mommies have some things to discuss in private." As they nodded and passed, she gave each a kiss on the cheek. Together with her wives, she watched them totter up the stairs with big smiles.

When they were certain no one was listening - confirmed by Twilight's detection spell - Twi spoke up. "So. How did it go? I mean, I kinda saw how it went out there with, ya know." She waved vaguely.

Sunset was the first to speak. "It was incredible. I'm a little bummed my dick wasn't as big, though."

Twi arched an eyebrow. "Noted. I'll have to look into that for the future."

"Also," Rainbow said. "You guys better develop an easier way of getting that spell thing done. I wanna do this more often! Having a dick rocks."

She and AJ high-fived. The rest murmured their general agreements. Sunset included.

Twi wiped the whiteboard clean, levitating a marker. "Well, I've still got the calculations in my head. Twilight, you wanna help me out?"

Twilight, in response, opened her mouth. A yawn came out before the words did. "Mmm, no thanks. I'm pretty beat after today."

Pinkie elbowed her. "Bet you wouldn't be saying that if it involved more seeeeeex~" she sang.

"Okay, yeah, but that's different! That doesn't involve any thinking, or complex arcano-technological mathematic equations!"

"Suuuure, whatever you say, Twitwi!"

Twi smiled. tucking the board under her arm. "Don't worry about it. I can do some of this solo tonight. Might need a coffee though. Do we still have dark roast?"

"Sure do." Sunset flung open the cabinet with her magic, feet away from the kitchen, and tossed the grounds over to Twi.

She'd never been one for coffee herself, but Twilight, AJ, Rainbow, and Pinkie all enjoyed a cup of joe. Pinkie only if said joe contained no less than four shots of creamer, and syrup so sweet and sticky it would give Rainbow a heart attack. The rest of them were tea girls. Rarity a tea snob, shocker there. Twilight was also a coffee snob, but nowhere near as big a snob as Rarity.

"Thanks. I'm gonna get the press running. Why don't you seven take tomorrow off?" She winked. "Afterwards, Twilight and I can work on a more compact version of that spell, something any of you with a horn can manage. Sound good?"

They all agreed. Before they turned to leave, Sunset took a handful of her nearest wives' rumps, giving the bountiful flesh a good squeeze.

"Sounds great~"

Author's Note

So many kids, they're finna need an orphanage. Alas, such is the consequence of mindless, uncontrollable breeding.
