Author's Note

I won’t lie, folks—this chapter gave me fits, but I’m actually quite happy with how it turned out. So I won’t keep you from getting to it, except for the usual content warning:

Chapter contains: One very rapey Shadowbolt girl getting hers, a futa thestral mare turned human, paizuri, imminent anal, and worst of all, science lessons regarding singularities—aka black holes—which are then used as improvised sex toys.

Thanks go to AJ_Aficionado for both the preread and allowing me use of his OC, and to Silverblade5 and Silentwoodfire for the usual array of edits and comments. They enjoyed this chapter and said it was the back and forth banter that sold it. But you be the judge.

12: Sour Sweetened Part 1 - v2

“Sour Sweet!” Midnight snarled as she magically plucked her classmate out of the bushes she was hiding in. But instead of pulling her forward, she threw her classmate backwards, pinning her against a large tree. Its branches sprouted tendrils that curled around the other girl’s wrists and ankles before pulling them apart, leaving her standing but spread-eagled and helpless.

Her school uniform had torn in several suggestive locations from the bush brambles that had snagged her when she was pulled free of them, breaking her vest button and leaving a large tear right over her left breast. To little surprise, given Midnight’s magical influence, it had gone clear through her bra without damaging the underlying skin and showed the outer edge of the areola, along with a significant area of the surrounding mammary, which was bulging through the rip.

I’d figured out by then that your boobs grew when you got turned on, as it enabled you to absorb more of Midnight’s mating magic, so clearly she liked at least some of what she’d seen, even in hiding. “We need to have a little talk about the way you’ve been treating me in gym class…”

Even though she was trapped, the freckled girl stared at Twilight in deliberate disdain. To her credit, she swallowed her fear and worked up some sass despite the danger she was in. “So good to see you, Sparkle!” she spoke sweetly at first, true to her name.

“Now listen... I know you’re a little upset and I’d be really happy to help you resolve all your sexual hang-ups, but I’m a bit tied up right now. And you know, you were a lot more my type when you weren’t a vengeful demigoddess drunk on her own power!”Her mood changed abruptly as she spat out the last words angrily, her fists clenching over her head.

“And what type is that?” Midnight all but snarled as she hovered before the other girl. Her body magically matured and grown, she now stood several inches taller than her classmate who, I noticed, was looking right into her cleavage. “Easy to bully and take advantage of? Never mind how much you enjoyed putting me down or feeling me up depending on your mood, do you have any idea how much I hated being around you in gym class?”

“It was all motivation!” Sour Sweet claimed with an ingratiating grin that made me want to pull an AJ and smack her on the spot, regardless of how deep Fluttershy’s tongue was working into me. “Just trying to help you bring up your gym scores! And besides, I wasn’t about to lose an athletic competition because you couldn’t pull your weight to save your life.” Her smile turned to a sneer.

“How thoughtful!” Midnight mimicked Sour Sweet’s former voice and mannerisms perfectly even as her eyes narrowed further. “The only motivation I got was to stay as far away from you as I could! But I suppose, to be fair, you did give me some genuinely helpful encouragement. Like when I was struggling to do a single pull-up, you squeezed my butt in front of everybody while I was hanging from the bar!” she hissed.

Though she paled, Sour Sweet couldn’t quite seem to help herself. “It worked, didn’t it? You pulled yourself up instantly! Hey, I was just trying to help you pass your fitness test, Sparkle!” she claimed ever-so-sweetly before she turned sullen again. “You were dragging down our class average and I didn’t want to lose to Indy’s third-period class again! And besides, your butt was too cute not to grope.” And this time, even in her sour state, her fingers flexed like they were squeezing something.

“And yanking off my shorts and panties afterwards in front of everyone while I was still up there clinging to the bar?” Midnight glared.

“Just trying to lighten your load!” Sour Sweet's voice went singsong again before dropping back to a growl. “You were embarrassing us. And you know you liked it...” she muttered under her breath as an afterthought, looking away.

“Sure I did. And what about chasing after me while we were running track, threatening to undress me if you caught me?” Midnight growled.

“Just giving you some incentive like any good classmate! You improved your best mile time by half a minute with me chasing you, making the minimum standard!” She grinned salaciously before turning grouchy again. “And if Coach Iron Will hadn’t shown up on the last lap, I would’ve caught you.”

Midnight stared at her, the sky darkening and wind increasing as her ire steadily grew. “And putting your hand beneath my chest when I was struggling to sustain a plank?” I got a distinct impression that she was giving Sour Sweet enough rope to hang herself.

“Hey, I waited until you were tired! You stayed up there for another twenty seconds, earning a passing score!” Sour Sweet pointed out eagerly before her mood shifted again, this time taking a tone I could only describe as sullen but sultry as she spoke under her breath. “I was just making sure we didn’t have to take remedial training with Iron Will because of you! And besides, I saw your tits go hard, right before they fell into my hands!” she finished with a leer. “Admit it, Sparkle. For as perverted as you’ve been acting here, you loved it.”

“‘Loved it’?” Midnight echoed derisively as a lightning bolt struck directly between her and Sour Sweet, causing the latter to flinch hard even as her own tits went rock hard while she awaited her fate; her breasts bulging out between her growing tears further. “Of course I did. Because there’s nothing that makes a girl feel better than being carried back to the clinic by you and Zesty with your hands all under my clothes!”

“Don’t blame us because you couldn’t get there without help! Iron Will told us to take you there! Besides, you didn’t fight us, filly.” She grinned again.

“Because I couldn’t!” Midnight snarled with another flash of lightning and sharp boom of thunder that even caused heads to turn towards her in worry from the dragon portal, where some of the drakes and drakinas were pointing and whispering even as they rutted. Still, I had to give Sour Sweet credit—the girl had some serious horse apples to go with her bipolar routine.

“My arms were too tired! And so were my legs after the run!” Midnight spat out. “I could barely walk or even lift a pencil the rest of the day! And once everybody else figured that out, I got groped every time I turned a corner!”

“Which means you got maximum benefit from the exercise!” Sour Sweet quickly pointed out eagerly with a lascivious look into Midnight’s now-ample cleavage. “Your performance that day was a credit to my motivational methods! And afterwards, I was just collecting payment for the personal training session. You’ve got a ripe and wriggly rear, Sparkle.”

The ground began to quake around Sour Sweet in direct reflection of Midnight’s growing rage as for the first time, I daresay I mentally gave Midnight blanket permission to do whatever she wanted to the other girl in retaliation.

But instead of doing so immediately, the tremors stopped as Midnight’s smile turned sickly-sweet. “You were such a Sweetie!” she mimicked in the same singsong voice, clasping her hands by her cheek as I’d seen Sour Sweet do. “It’s all true, I passed my fitness test and got to the clinic thanks to you! And you say I owed you payment? In that case, I know exactly how I can repay you!”

“How’s that? By letting me give you an Archery lesson so you don’t embarrass us again?” Sour Sweet suggested hopefully, then glared over at where Applejack and Rainbow Dash were in an intimate heap with each other by the ground portal. “And now I’m jealous of AJ for getting her paws on you…”

“Oh, please!” Applejack called out from her back. “Unlike the rest of y’all, I wasn’t trying to molest her!”

“What the hell kind of school is Crystal Prep?” Rainbow Dash asked aloud in a disgust that belied her lovemaking with Applejack. Have to say, I’d never seen those two go at it, but they were sure enjoying each other now. “Is everybody there a colossal pervert?”

“No. Just completely cutthroat in all aspects of social and sexual interaction in a place where winning and personal status was prized over friendship and healthy relationships,” Sugarcoat admitted as she now eagerly stroked the lower phallus of her stallion suitor, hugging the enormous lower shaft it to her belly and chest as the upper remained embedded deep within her proverbial tail. “And it started at the top with Principal Cinch.”

“It wasn’t always like that!” Dean Cadance shouted from the upper floor window where she continued to make out passionately with an equally naked Celestia. Luna herself wasn’t visible except for a single blue leg draped over her sibling’s shoulder, leaving me thinking she was lying beneath the pair, servicing Cadance orally while Celestia ground her marehood against her sister’s.

“When Principal Sombra was here, he was hard but fair! He demanded excellence, but not at the expense of tearing each other down!” she claimed as a new portal opened beside them to what looked like the interior of a Changeling hive, causing the startled faces and the pupil-less green eyes of the insectile drones that inhabited it to turn towards the scene in shock.

“Oh, he was hard all right…” Principal Celestia admitted between kisses of Cadance and Luna’s leg between them. “When our schools competed, it was for bragging rights and who got to be on top!”

“Wow. You were a really poor Principal, Abacus Cinch,” Maud told her as she continued to lovingly lick and caress every inch of Cinch’s now-naked stony form; to her credit, the Crystal Prep school head looked pretty good for being middle-aged, at least as much as I could tell given she was now rendered in granite. “But you’re also a really good lover and an excellent listener. So I forgive you.” She dropped between Cinch’s petrified legs and began licking at their junction; I wasn’t sure, but I thought I might have seen actual honey running down her petrified thighs.

“You heard it straight from the horse’s mouth, Rainbow Dash,” Midnight said, noting Maud’s remarks and the new race in passing but otherwise paying them little mind. “It was, as Sugarcoat says, as unhealthy a social and sexual environment as you could have. And to think that Sour Sweet here was only the second-worst offender,” she growled.

“Only second? I’m insulted,” Sour Sweet replied with a sneer. “I always get my girl, Sparkle. I wasn’t about to let Zesty have you before me. And besides, have you ever thought that you were just so adorably needy and had such a beautiful butt that I just wanted to help you?” Sour Sweet suggested with an infuriatingly ingratiating grin before her expression dropped again.

“Or maybe you were just so cute but timid that I just wanted to help myself to you…” her sour personality couldn’t help but admit; I couldn’t help but note in turn that she switched between the two parts of her dual persona even easier than Pinkie Pie did.

Midnight’s glowing, violet-rimmed eyes narrowed again. “Between chasing me in gym class and trying to molest all the incoming freshgirls, I will never understand how you found the time to master physics and quantum theory.”

“And I’ll never understand why you never wanted to be touched given you could have used your pretty purple pussy to have all the guys and girls at Crystal Prep on a string!” Sour Sweet instantly retorted.

“Brains and beauty, Sparkle. You had them both, but you never used them for anything except pointless pursuits like your obsessive investigations into magic! Such a waste of body and mind!You may as well have just taken all your potential and thrown it all into a supermassive singularity,” she said to dig her claws in deeper; I got the impression that her put-downs were how she cowed other girls and made them amenable to her advances, which just made her all the more despicable in my eyes. And those of AJ and Rainbow, given I heard the latter growl.

“Well, those investigations bore fruit! And I don’t think we’ll need a supermassive singularity. Not when a miniature one will do...” Midnight stated, the wind starting to whip around her as both electricity and raw arcane energy crackled, dazzling my magical awareness with how much power she was pouring into a single point. She held her gloved hands as if they were cupping a small ball as she fed it with more and more magic into it until suddenly, a black dot appeared that seemed to distort the very air around it.

She continued to feed it aura from what seemed like her limitless reserves until the inky blackness grew to roughly the size of a basketball, though she had it confined in some sort of stasis field, then held it before an agape Sour Sweet, who was struck speechless for one of the few times in her life.

I didn’t blame her as I stared in awe at the impossible feat. Had that goddess of a girl just created a freaking black hole?

“So what do you think, Sour Sweet?” Midnight then held it up before her. It seemed to distort the very light around it, bending it like a funhouse mirror around a basketball-sized globe. “I made it just for you! A pristine, non-rotating singularity—the so-called ‘Eternal’ black hole. These don’t occur in nature, you know! And at this size, they’d hardly be ‘eternal’ given they’d evaporate quickly from Hawking radiation, but don’t worry—I’m preventing that from happening. And restricting its more deleterious effects… for now.”

“But… how?” Sour Sweet stared at the celestial construct in a mixture of horror and wonder.

“Magic.” Midnight’s grin turned evil again. “That ‘pointless pursuit’ you mentioned before. I have to admit, it’s kind of fun holding a black hole in my hand. Still, a non-rotating black hole is rather boring—even its Penrose diagram is disgustingly simple, possessing only a single reflected reality…”

“So let’s make it more interesting, shall we? Let me just start it spinning…”

She balanced it on a gloved finger as she focused her magic, then began making motions with her other hand like she was spinning a basketball. Her inflowing magic started whirling faster and faster around the edges as it flattened into an accretion disk that caused the entire singularity edge to glow as light was bent around it.

The faster it spun, the more the singularity’s distortion slowly distended, making the impossible object bulge out from the equator while shrinking into itself at the poles like a doughnut with not a hole but shallow divots on both sides.

“Almost there…” Midnight announced as Sour Sweet could only gape. I didn’t know what she was trying to do until suddenly, the pitch-black central area abruptly became see-through, showing a dark ring as well as a roiling storm of energy inside. “Got it! So, Sour Sweet… what do your physics and quantum theory texts say about this?” She floated it closer and presented it to the other girl, causing strands of her green and magenta hair to reach up towards it from the front of her scalp.

“What… what did you…” I got the distinct impression that Sour Sweet already knew what it was but somehow couldn’t accept it.

“I sped up its rotation to superluminal speeds to reach an R-value of 1! I’m sure you know what happens when the outer and inner event horizons merge?” Midnight explained triumphantly.

“A naked singularity?” Sour Sweet gaped anew. “But... the Cosmic Censorship Hypothesis makes that impossible!”

“Right in one! A naked singularity. Apt, don’t you think, given our general state of undress?” Midnight grinned; she was clearly immensely enjoying the banter. “And there’s this funny thing about magic, Sour Sweet—enough of it makes everything possible. Unlike with our realm, it allows for very easy transitions between matter and energy… and back!

“So, I simply fed a tiny area of space enough magical energy and converted it to mass until it surpassed the critical value, then spun it up to superluminal speeds. And now I hold the ultimate universal power in my hands…” Midnight said gleefully, staring at it like she was mesmerized by a flame. “So tell me, Sour Sweet.. if I dropped my shield, what do you think would happen?”

Sour Sweet drew back as much as the tree she was bound to would allow. “Are you trying to destroy all reality, Sparkle?” she asked in an uncharacteristically shaky voice.

“Now why would I do that? I just wanted to make something suitable to your interests as a tool for your sensual punishment!”

“Now why would I think you would?” Sour Sweet replied in her sour voice, though it sounded more unsteady than snarky. “Maybe it was the all the tears you’ve made in freaking spacetime!" She blanched hard as she found herself staring the singularity in the face.

But Midnight only laughed. “Those are but simple interdimensional rifts, easily sealed by my power. But I’d much rather leave them open right now given we’re learning so much about the different Equestrian races! Besides, you of all students should know that black holes have but three properties, Sour Sweet: mass, charge, and spin. My creation is no different! But by charging it with magic instead of electricity, I can make it far less indiscriminate in its effects! For example…”

She moved it close to the neck of the still-clothed girl, causing her to whimper in fear. But there was no visible effect on her even as the front of her bow seemed to dissolve in slow motion as it neared the darkened globe, turning into thin strings of dust-like matter that flowed directly into the impossibly dense orb.

Midnight then moved it fractionally closer, causing the effect to spread wider, progressively dissolving her classmate’s clothes with extreme but carefully targeted tidal gravity around the impossibly small singularity, leaving an expanding circular arc of bare skin that soon included the start of her cleavage. “Enjoying the caress of the ergosphere? Since it was made with my magic, I can modify the singularity’s gravitational and time dilation effects to limit them to anything I want—like your clothes!”

She then moved the torus-like anomaly lower, to the bottom of Sour Sweet’s plaid skirt to begin erasing it from the bottom up, though she stopped it short of her crotch, leaving her showing just a hint of her panties.

“Of course, all infalling matter would normally appear to freeze in time from an outside perspective at the event horizon. But strip the event horizons away? Some very interesting effects can then be realized,” she mused as she then withdrew the orb slightly, the positioned it right over the girl’s left breast and moved it inwards again, causing her blouse and underlying bra to slowly dissolve her top in a steadily growing circle, sucking the matter into its maw in slow motion.

The effect started at her sorely erect nipple and moved outwards, baring first one breast and then the other to reveal that she had pierced nipples, with double-ended studs at oblique mirrored angles through both.

“Wow… b-bet her ma didn’t approve o’ that…” a distracted Applejack said as she sat up while Rainbow’s hand snaked between her legs.

“You said it!” Rainbow answered from atop her, not taking her eyes off Midnight and Sour Sweet even as she began to probe her friend.

“How garish!” An otherwise occupied Rarity said from across the dragon portal in an intrigued tone as she took a turn with the females, who were bathing her with their tongues and hot breath from head to toe. From what I could hear, they seemed particularly enamored of her spearmint flavor, which they found impossibly but quite pleasantly cooling on their normally hot maws and tongues.

“I think they’re neato! I hear they make boobs real sensitive! In fact, I bet you’d look good with them, Rares!” Pinkie proclaimed as she sat at the center of attention of four dragon drakes. “So how about it, boys? Can you make gold studs like she wears?”

“Using gold from our hoards? No problem!” Rift Zone promised as he held her up and took her tail from behind.

“Wow. Nice!” Midnight herself said in approval as she withdrew her impossible creation enough to behold both the piercings before returning it to float it over Sour Sweet’s crotch, shortly revealing her furless marehood as Sour Sweet could only squirm and whimper; I was getting the distinct feeling that she was reacting to not just being unclothed in such an exotic and scientifically improbable manner, but the caress of the cosmic creation itself.

“Would you look at that… nipple and clit piercings on top of a shaved pussy! So, Sour, just who were you trying to impress?” the transformed Twilight asked as she continued to run the outer edge of the singularity over the remains of the girl’s clothes, erasing them from existence until they sloughed off her entirely.

“Principal Cinch!” her sweet side answered automatically and eagerly; I was quickly learning that side of her personality had almost as much compunction to tell the unspoken truth as Sugarcoat. “She liked them. It’s how she marked her favorite girls! And besides, Zesty was right. The studs do increase sensitivity…” She wriggled them at Midnight in something approaching enticement

“Told ya!” Lemon Zest’s voice rang out, though with all the wind and other distortions around, I couldn’t tell where she was.

Midnight smirked. She then allowed more of the black hole’s gravity to be felt, causing it to slurp up the remains of Sour Sweet’s clothes quickly, leaving her as naked as the singularity before her. And either from Midnight’s mating aura or from the touch of the impossible artifact, it left her sorely aroused with her teats rigid and fluid coating her thighs.

“Zesty is going to get hers shortly. But my focus is on you for now, Sour Sweet. So how best to punish you...” She caressed the other girl’s freckled light orange cheek with the edge of the singularity’s distortion, causing the skin to ripple and the other girl to take a shuddering gasp at the contact. “Given how much you like girls, maybe I should just make you a threesome with Indy and Sunny over there?”

“No!” The latter two shouted from their involuntary erotic embrace before Midnight silenced them by causing two facsimiles of Abyssinian organs to grow from the basalt bench behind them. They sprouted upwards and began pushing directly into their tails, stretching them out further.

The question seemed to trigger another of Sour Sweet’s patented mood swings. “Girls are fun!” Her face lit up, only to just as quickly fall. “But not those two....”

“Yeah, because last time you tried groping me, I broke your freakin’ wrist!” Indigo reminded her through gritted teeth.

“Wow… I think I’m starting to like her, AJ!” Rainbow noted as she buried three fingers in her girlfriend’s snatch.

“Figures… Ya always did go for the lunkhead types!” Applejack teased as she propped herself on her hands, arching her back against the contact..

“Well, why do you think I’m in love with you?” Rainbow instantly turned it back on her as Indigo could only growl.

Midnight noted the exchange in passing, giving them a glance and smirk. “Aw… since when have you ever been shy about feeling up females, Sweetie? Or are they only ‘fun’ if they don’t fight back? Well, it’s too late now!” Midnight mocked in Sour Sweet’s own voice. “Now as to your punishment…”

Her voice trailed off as a new portal opened beside them, and this one wasn’t one of the usual ragged rips or rifts in reality she had created. It was a near-perfect circle with a fluorescing blue rim through which I could see what appeared to be an opulent chamber lit by firegems with white stone walls, and as I watched, a new equine being stepped directly through it.

She was of alicorn size and appearance given she had both large wings and a long unicorn horn. But her wings were membrane instead of feathered; her eyes were slitted like the Nighborne thestrals I could see through the portal by Roseluck and the other two flower girls, but a pale yellow that paired with an equally pallid, barely-pink coat.

She was staring in awe—not at a surprised Midnight but at the singularity she had created and still sat beside her, hovering placidly before them except for the continuing inflow of discarded clothes, which I’m sorry to say included my favorite leather jacket as it seemed to suck up every single thread of fabric within range.

“So the Nether spoke true…” the new arrival whispered in a slightly odd accent, falling to her knees before the impossible creation. “The greatest engine of cosmic creation and destruction laid bare… yet held in thrall by an impossibly large magical power…” she said mostly to herself, far more interested in the black hole before her than the sex going on around her.

And from what I knew of her, that was in itself almost an impossible feat. The High Priestess? HERE? was all I could immediately think as Fluttershy continued to eat me out from behind; her tongue never tiring for as long as her kindness didn’t run out.

It was only then the new arrival turned to Midnight and all but prostrated herself before her. “Greetings from the Temple of Karabor in the sovereign state of Batican City, young human goddess. I am Juniper Neptune XXX, High Priestess of the Highborne Thestrals and steward of the sacred energies of the Twisting Nether.”

She bowed low before Midnight, not caring in the least that her silk robe and crystal slippers were being dissolved right off her body, revealing an enormous equine organ that hung half-hard beneath her belly.

“And what you have created is what all my line has sought for centuries—the ultimate engine of destruction and creation! The ability to travel freely and cross into different realms—even create them! For it is said that to unshroud the sacred vortex is to enable access to all times and realms!” she explained almost frantically, flaring her large wings in deep respect.

“I beseech thee, young goddess… please allow me access to it! By all thirty of my long line, please teach me how to use it!”

“I see…” Midnight considered her curiously, a gaping Sour Sweet momentarily forgotten; I couldn’t help but note that the Nightborne on the other side of the portal by Roseluck and the other two flower girls were staring in shock at her, pointing and whispering excitedly to themselves.

“You believe that by creating a naked singularity, I have in fact opened an accessible Einstein-Rosen bridge. You believe it would enable you to travel great distances and even explore parallel universes—perhaps you could even access a newborn universe on the other side, where the black hole turns into a white hole, molding it as you would wish!”

“But… white holes are a myth!” a badly flushed and freaked Sour Sweet shouted, both her personalities united for one rare moment—which was an amazing accomplishment in and of itself. “Look at the damned Penrose diagram! They can only exist in the infinite past!”

“Of our universe, perhaps. But of a brand-new one at the start of time?” Midnight retorted. “Our esteemed visitor is correct. To create a naked singularity means that the possibilities of research—of all reality—are endless! It would enable you to travel not just through vast distances of space, but even through time itself! And yet, such purely scientific pursuits must wait. I would explore them myself in the presence of our honored guest, but business before pleasure, after all.”

She favored the thestralcorn priestess with a nod. “Greetings to you, Juniper Neptune the XXXth. I must admit, I am very impressed that you were able to come here, crossing the realms of your own accord. Your portal spell is well-designed and surprisingly stable. I might wish to make use of it myself instead of tearing such crude rifts in reality.”

“It is yours to use as you see fit! But it does have limits. I was only able to cross because the chaotic energies and weakened interdimensional barriers you have caused allowed my power to produce one—something that normally is only the case during rare interstellar ley line convergences! I admit I feared for the safety of both realms should I sunder the boundaries further, but how could I not come? Not see this magnificent creation for myself?”

She got as close to it as she dared, staring transfixed at the twisted torus shape and swirling energies within the black orb—none of which should even have been visible but for the fact the event horizons had been impossibly stripped away.

“It is the very embodiment of both infinity and eternity… a portal to all possibilities! I know not how you created it, but I humbly ask again that you show me its secrets. Teach me how to make it! And how to use it!”

Midnight’s smile only grew. “Very well, Juniper Neptune. As you have been nothing but reverent and respectful—completely unlike my classmates!—I will grant your wish. But first, you must do something for me.”

“And how may I serve a goddess?” the High Priestess asked, bowing low.

Midnight grinned. “I could not help but note you have some extra… equipment,” she nodded down at the impressive and now-rigidly erect phallus beneath the thestralcorn mare’s belly; it was nearly as large as the one rutting Sugarcoat, who for once, had fallen completely silent as she stared openmouthed. “Please tell me—how did you come about that? Did I somehow do it?”

“My stallionhood? No. I have had it ever since my ascension to High Priestess. It is a long story, but it is both the boon and the curse of my line.” She stretched out her now-naked body to show it off. “If the price for your aid is to serve you with it, then I will gladly pay it!”

“Wait—she’s a dickgirl?” Sour Sweet recoiled, but both mages ignored her.

“Don’t insult her! It’s called futa if she’s got both sets of gear!” Jet Set reminded her with a glance over his shoulder.

“Figures you’d like it! Futa is so gay!” a disgusted Upper Crust claimed from where she was still bound to the wall, though her doppleganger continued to feed and fondle the eight felines as her many mammaries endlessly oozed milk.

“No, it isn’t!” he shouted back, at which point a massive argument erupted on the Crystal Prep side of the field that would have done certain online forums proud.

Midnight rolled her eyes but otherwise paid them no mind. “Long stories are so tiresome. As you are clearly an incredibly powerful mage—I might even call you a peer!—let us simply share our thoughts and memories…” She closed her eyes in concentration as she cast a telepathy spell; one rapidly matched by a far more practiced and elegant one from the High Priestess.

Ten seconds elapsed before the two opened their eyes again.

“I see. You are the latest in a long line of Juniper Neptunes; not immortal but passing on your powers, physical attributes, and memories to each new host in turn,” Midnight recited. “Your male equipment and insatiable sexual appetites came from the original High Priestess, who sought to usurp the prevailing order and gain godhood in some rather… questionable ways.

“But you have different motivations than your progenitor. You seek the secrets to ultimate cosmic power and knowledge for the benefit of not just yourself, but the entire Highborne race.”

“And you, Midnight Sparkle, are the ultimate expression and avatar of magic itself,” Juniper rejoined. “Your ascension was accidental, but not undeserved given your brilliant mind and equally ceaseless efforts to understand the arcane energies of my world!

“But before leaving this realm behind forever to live as the goddess you have become, you wish to punish those who tormented you and reward those who helped you.” She motioned with a large bat wing at the scene around her as if it was normal. Which given her line’s well-known proclivities—ceaselessly horny and always at least half-erect from what I’d read—it might well have been.

Her next words confirmed it. “I wholeheartedly approve of such sentiments and appreciate your rather inventive methods, given they are not far removed from how I… mark holy days and discipline disobedient disciples.” Her organ twitched hard as her long chiropteran tongue circled her muzzle as she bared her sharp teeth in a salacious grin.

“If you will grant me the secrets of this shroudless ‘singularity’ as you call it, I will be more than happy to serve you however you wish. Including helping you with such enjoyable endeavors.” She lowered her head and splayed her wings in a formal bow.

“Very well, Juniper Neptune—you are truly a mare after my own heart! I accept your gracious offer, and in turn, I offer up my next punishment to you. Before you stands the human girl known as Sour Sweet—I’m sure you know her crimes against me well from my shared memories.”

“I do indeed,” the High Priestess said thinly, turning to stare at the girl, sizing her up little differently than she would a piece of meat—which, it should be said here, bat-ponies do eat; the dark-furred Nightborne in particular had many rituals around hunting.

“I am only too familiar with her ilk, as my line has encountered them repeatedly in the past. So be assured that the thirty lifetimes of memory within me means I know well how to deal with them. I will simply treat her as I would a boastful and unruly acolyte who does not know her place. So the only question before me now is simple: just how shall I deal with you, you insulting, intrusive and abusive filly?”

She turned to the human girl and regarded her lazily as Sour Sweet struggled mightily not to shake. “I gather from your earlier words that you are knowledgeable of these holy objects as well. You clearly understand their great potential, but shall we see what more personal pursuits they allow for?” She brought it closer with an evil grin..

“Be careful with that thing…” Sour Sweet’s voice had gone noticeably unsteady again.

“Worry not. It is true that the embrace of the sacred vortex is final and normally inescapable. But as your former ‘schoolmate’ has made plain, this one is charged with massive amounts of magic instead of mere mass. And with it, she has removed its normally impenetrable shroud, unveiling its interior.

“Though I very much wish to use it immediately to explore and shape new realms—it is truly a tool of the Gods!—there are other, far more mundane uses for it. So, let us see how I might manipulate it to serve far more sensual ends… with your permission, Midnight Sparkle?” she hastened to add with a glance back.

“You have it,” Midnight said with an eager grin and nod as she floated back a few steps to watch. “And be honored, Sour Sweet. I was just planning to punish you with one of your favorite celestial subjects, but it turns out you’re going to be a scientific pioneer—the first to experience and observe the insides of a naked singularity!

“Oh, I’m so honored to see my body matter spaghettified and reduced to quantum dust by extreme tidal gravity!” she said sweetly, if somewhat sickly. To her credit, she followed that up by shifting moods and even actually managing some sullen snark again. “I bet Stephen Hawking never had to put up with this…”

Juniper’s slitted yellow eyes narrowed. “No. Stephen Hawking—peace be upon him—just had to ‘put up’ with a crippling disease that progressively destroyed the use of his body. But did he stop his search for knowledge? Not at all,” the High Priestess announced in annoyance, earning a shocked look from Sour Sweet and even a startled one from Midnight.

“For seeking understanding of all space and time, as well as making discoveries not even my line knew of, I very much respect him as both a peer and a prophet. In truth, I would have invited him to the Temple of Karabor and made him an honorary Sage of the Stars if I could. But sadly, even before his death he was too frail to make the journey, and repairing his broken body was beyond even my considerable power.” She closed her eyes in regret, and even Midnight seemed to be given pause; she fell silent and looked away upon hearing the story.

For one of the few times in her life, Sour Sweet looked speechless. “You met him?”

“Of course I did! Do not be surprised, obtuse and insulting young mare. My line seeks to tap the infinite power and possibilities of the Twisting Nether, or the multiverse as you call it, and we are not picky about where the knowledge to do so comes from! I actually have a Penrose diagram I borrowed from your world in my personal study,” she noted as she projected an image of it from her horn into the air.

“Needless to say, I am more than happy to learn what insights human science has to offer on the subject, and to that end, I have read his books and even sat in on his seminars,” she concluded as she cut the projection.

“Looking like that?” Sour Sweet gaped at her thestralcorn form.

“No. Like this.” The leucistic mare grinned as her horn glowed. Her form seemed to not so much change as flow as she stood upright and fluidly transformed into a human, her barely pink fur melting into very pallid skin while her ample teats migrated from her crotch to her chest. Either by accident or design, they caressed the sides of her rigidly erect organ as they did so, causing her to hum happily.

When her transformation was finished before a newly shocked Sour Sweet, she was a tall and slender human woman with pure white hair and pale yellow eyes; her skin only a slight shade of pink less pallid than her mane.

She was utterly gorgeous by any standard, doubly so as she had made it a point to keep her horn, cat eyes, bat-wings and fangs in her new form, giving her the appearance of a voluptuous vampire queen.

“Once again, you impress me, Juniper Neptune,” Midnight complimented, openly ogling her admittedly impressive curves, which included a large set of apples and still-equine organ that hung at nearly the same level as Sour Sweet’s crotch. “That is a very smooth and well-practiced spell.”

“Thank you, Midnight Sparkle. I cannot say it was my invention—Juniper Neptune the 19th has that honor—but it is one I am quite well-versed in after eleven lifetimes of practice. Meet my human form, young Sour Sweet, though I normally hide my horn, wings and pointed teeth.” she bared them with her grin, causing Sour Sweet to shiver and lick her lips nervously. “I see you like it as well? I do admit this upright body has certain… advantages over a purely equine one.

“I would be lying if I said I had not indulged myself in this form with a few lucky members of your race… though some of the men I mated did have to get over a certain shock.” She gave a toothy grin as she reached down to stroke her shaft. “But they came around quickly enough, like all of my stallion acolytes. Or perhaps I should say, they came quickly enough when they discovered they enjoyed having their tails taken. So it will be with you.”

She grinned leeringly as she nodded down at her eighteen-inch erection, which was no smaller than what it had been as a pony. She placed its tip between Sour Sweet’s spread legs, not quite touching her but dangerously close to doing so. “Be honored, Sour Sweet. For the High Priestess does not normally lower herself to rutting school-age fillies!”

“Well, I’m not! Dick is ick!” Sour Sweet stared down at the equine organ in revulsion, only for her gaze to quickly turn rapt. “Unless it’s attached to a really hot chick…” her other personality spoke up, causing her to gape and clamp her jaw shut while her classmates began to laugh.

“Hate it, do you? Then you insult not just me, but my entire line, you two-faced filly!” Arcane energies distinct from Midnight’s started to swirl around her. “Though I will grant you some leniency for being referred to as a ‘really hot chick’… I will make sure you enjoy yourself, as much as I know at least half of you would hate that.”

“Actually, all of her will. She hates it when she’s not in control,” Sugarcoat offered unhelpfully even as she approached climax again, earning a sharp glare.

“Do you ever shut your mouth, Sugarcoat?” Sour Sweet snarled.

“Look who’s talking!” Sunny Flare shouted around kisses of Indigo, the two now rotated towards each other so they could continue to make out while still planted firmly on the phallic constructs beneath them.

“We hate her too! So give that cock-hating bitch every inch, miss vampire queen!” Indigo demanded.

“Vampire…” Juniper rolled her eyes and shook her head in disgust. “Your classmates try even my patience, Midnight Sparkle.”

“I know. But that just makes punishing them all the sweeter,” Midnight pointed out with a smile. “And I eagerly wait to see what you plan to do with her.”

“Then you shall wait no longer! Let us start with this…” she floated the slightly donut-shaped black hole closer and brushed a cringing Sour Sweet with its periphery; it was hard to see around the gravitational distortion but it looked like she moved the outer edge of the distortion field—I think it was called the ergosphere? Or at this point, should that be the erogenousphere?—over the captive girl’s left breast.

The sweating but sorely aroused girl visibly bit off a gasp as it tugged on her mammary with invisible force, drawing more blood into it and the pierced teat that capped it. The nipple actually stuck to the singularity—or excuse me, ringularity since it was spinning at superluminal speeds—briefly, but then impossibly, it released it, as it was then drawn away, causing her breast to recoil and bounce upwards in slow motion.

Sour Sweet had to bite off a sharp gasp. “Wha…?” she said in disbelief as Juniper grinned knowingly.

“Remarkable, isn’t it? Without its sacred shroud, the vortex becomes fully escapable and the ‘singularity’ itself accessible, along with its accompanying ‘wormhole’ to other times and places—though in truth, I despise the latter term, for making it sound like an invertebrate-dug tunnel!

“But no matter. I’m sure you also note how time slowed down in its presence, resulting in a much longer-lasting, low wave of pleasure instead of a short burst,” the High Priestess noted as if she was giving an erotic seminar.

“Thanks to your former classmate’s magic, I can now control just what it affects and how strongly. But make no mistake, Sour Sweet—it is no less irresistible. As am I!”

She bent the tree Sour Sweet was bound backwards to lay her flat with an arched back; it gave a sharp creak but did not break. She then stepped forward to straddle the shaking Shadowbolt girl, nestling her long half-equine, half-avian erection between the schoolgirl’s studded breasts with its drooling tip dangling before her quivering mouth.

Juniper smiled toothily as she watched the girl try to resist her own urges as well as the sight and smell of the large equine organ hovering just beneath her nose. “You can resist me no more than could my male acolytes, human girl. But please don’t think I’m picky, for I can certainly enjoy females. I would tell you to service me with your teats—that is one ability I do appreciate humans have!—but as your limbs are unavailable for now…”

The High Priestess lowered the naked singularity over Sour Sweet’s chest, causing her breasts to bulge upwards towards them again; her teats stretching towards the impossible orb as if reaching for it. Juniper then began moving the cosmic construct back and forth over her chest to control the motion of her mammaries, causing them to caress and press into the sides of her eighteen-inch shaft with each pass.

“Look, ma… no hands!” AJ said in amazement as the pair momentarily stopped their lovemaking to stare; even Rainbow Dash was taking a keen interest in the proceedings. And she hated science class!

“Now that is inventive,” Midnight said in approval, watching from her hover over crossed arms.

“Thank you again, Midnight Sparkle. But we’re just getting started! Time for your first taste of ‘dick’, Sour Sweet,” she announced as she pushed forward slightly to part her lips, still using the singularity to stroke herself with the Shadowbolt girl’s boobs.

“I… hate… dick…” She managed one final weak denial even as her body began arching sensually upwards with each tug of the singularity’s passing, pushing herself into it fully..

“Unless it’s attached to a ‘really hot chick’,” Juniper reminded her with an evil grin. “And I am!” she added triumphantly as Sour Sweet’s lips finally gave way and allowed her access, silencing her to the cheers of her classmates..

“Yesss….” Juniper closed her eyes and gave a slight sound not far removed from a very bat-like scree as she sunk her first two inches to a series of whistles and appreciative claps from the Shadowbolt side of the field. “Such a silken tongue for such an insulting girl. You have potential, Sour Sweet—as both a thestralcorn concubine and as an arcane theorist. I may well request permission from your former classmate to take you back with me so I can train you properly in both arts.”

“Oh! Would you?” Sunny Flare shouted between kisses of Indigo, the pair clutching at each other as they neared their latest orgasm, backlit by a fresh eruption of lava on the other side of the dragon portal. “That alone would make this whole sex-crazy day worth it!” she said as she exchanged a high-hoof with Indy, to which Sour Sweet’s only reaction was a raised middle finger in their direction.

“That would be my pleasure. But first, we must do something about your disciplinary issues...” The High Priestess increased the pull of gravity to both massage her shaft harder with and pull Sour Sweet’s head up further. The latter, it quickly became clear, was to get more of her strangely unaffected organ inside of her muzzle. With nearly a third of it in her, the freaked and freckled girl could only stare down the shaft wide-eyed and suckle it helplessly, but also increasingly eagerly.

“Very good. Just the right amount of pressure. You know, for somecreature who doesn’t like ‘dick’, you are showing yourself masterful in orally pleasuring one, young filly.”

“You hear that, Sunny?” Jet Set called out. “She got it right her first time! And so did Trenderhoof here! So why the hell can’t you?”

“Oh, will you give it a freakin’ rest already?” Sunny snarled as she arched her head while a laughing Indigo nibbled at her neck.

I noticed both Juniper and Midnight rolled their eyes. “A good start. But the climax is the most important part. When I come, you will swallow every drop, young girl. If you do not…” the former grinned unpleasantly, flashing her fangs again. “Well. Be assured then that I will find other uses for this vortex. And be warned, I come gallons! Or liters, if you prefer”

“Do ponies use Imperial or metric?” Sugarcoat wondered aloud as she was again dangled over an open portal, this one appearing to be over a strange house in the Everfree, which drew out a gold-adorned zebra mare who looked up and gaped.

“I knew something was amiss. But what in all the realms is this?” she asked as she stared transfixed at the scene.

True to form, even naked and being driven towards climax again by her insatiable equine lover, Sugarcoat didn’t miss a beat. “Oh, hello. Sorry about all this, Ms. Zebra, but don’t mind me. I’m just getting magically screwed by my sex-crazed schoolmate as punishment for crimes of character.”

I might have listened further to the exchange except Juniper chose that moment to climax powerfully, leaning into Sour Sweet’s body as she erupted hard into her muzzle.

The normally talkative Shadowbolt girl gave a muffled squeal as she struggled to contain it all, and to her credit, she almost succeeded, swallowing the seed until Juniper’s shaft slipped out of her muzzle halfway through and fountained all over her face, though some of it caught in the gravity well and spiraled into the singularity.

“So, Sour Sweet… it would seem you could not obey even the simplest of instructions…” a still-lustful Juniper began ominously as a dazed Sour Sweet could only lie there panting softly while licking at her cheeks; when she opened her violet eyes again, I saw that they had gone slitted!

“In that case, further punishment is warranted…” She magically released Sour Sweet’s legs from the tree tendrils that bound them, but then used the black hole’s pull to tug them up and over her head, leaving her curled over with her shaven marehood and tail fully exposed.

“Wow. Look at all that flexibility!” Rainbow Dash mocked as she was contorted like a gymnast but didn’t look in the least bit uncomfortable; her feet shortly tied over her head, presenting her clean-shaven nethers. “You’d give Blossomforth over there a run!”

“Hey!” a new voice broke in from where Blossomforth and Cloud Kicker were intertwined. “Nobody’s more flexible than me, Rainbow!”

“Oh yeah? Reckon Sour Sweet there’ll take that bet!” Applejack retorted.

“Well, she was always good on the uneven bars,” Indigo noted as she reached down to spread Sunny’s cheeks further so she could sink the feline phallus deeper into her depths. “Enjoying yourself over there, Miss Molester?”

“Oh, sure! I’m just loving having my body violated by some otherworldly equine goth queen using a freaking black hole!” Sour Sweet shouted.

“Do you ever shut up, girl?” An annoyed Juniper Neptune asked even as she began to tease Sour Sweet’s shaven marehood in earnest with both her aura and the tug of gravity on her clit piercing, repeatedly tweaking it to elicit a series of startled and quite pleasured gasps that at least briefly succeeded in silencing her.

“And for the record, black hole is a woefully inadequate and inaccurate term for all they are! Your so-called ‘singularities’ are a tool of not just travel but universal renewal; one my line reveres! And yet, they were unusable, for to cross the point of no return always presented an insurmountable obstacle to realizing their full potential—to use them as the portals to and incubators of the new realms we sought to reach! But this so-called ‘naked’ singularity solves that! Though I admit I had not thought of using them in such sensual manners before this day.”

“So glad to be of service…” Sour Sweet said weakly as she awaited the inevitable. “And I still think dick is ick!”

“Then you have a funny way of showing it. I also cannot help but note you have acquired thestral eyes—how interesting! And I saw from Midnight Sparkle’s memories that this is not the first time that has happened.

“Very well then—I am as curious as her. So shall we see what other effects her mating magic crossed with my own may have under the black light of this sacred star…?” she suggested as she positioned her hybrid cock against the entrance of Sour Sweet’s rosebud tail, preparing to insert its tapered tip.
