What Diamond Deserves

Everything was going wrong. Apple Bloom knew she was dwelling, but it was difficult not to dwell when everything she did reminded her of Diamond Tiara. Perhaps if she'd made an attempt earlier – much earlier – to get her mind off of the subject, it might have been a more feasible proposition. But as the day wore on, the subject of Tiara had progressively become more and more inescapable. Even when she wasn't fucking there. Bloom was slowly piecing together the rules for... whatever it was that was going on, but it was very clear at this point that it was too little, too late.

No, after what had happened at Carousel Boutique, she was certain that there was no one she could go to for help. Anyone who could help wouldn't even realize there was a problem, and any attempt she might make to convince them otherwise would likely just make things worse. That was the real sticking point. Zecora was likely to be outside the influence of Tiara now, yes, and more than willing to help her figure this out. But so much as explaining what she needed help with would make the problem worse, and Bloom had no idea how long Zecora would remain safely outside of Tiara's influence. She might even have already been swept up for all she knew. Looking for more information on her own at the Library had briefly popped into her mind as an option, but it was ultimately too public a setting. She couldn't risk running into Tiara, or Silver Spoon, or even just having Twilight or Spike ask her what she was looking up. No, she was thoroughly on her own on this. With no help, no information, no resources, and no clue where to start, she was, to put it mildly, royally fucked. The only idea she had left was to get somewhere where she could isolate herself. Where she could be absolutely certain that there was no risk of talking about Diamond Tiara to anypony while she planned her next move. There was only one place in Ponyville that fit the bill even remotely.

Her bedroom. If she locked her door, she could be fairly certain that her family would grudgingly respect her privacy. It wasn't great, but it was the best she could hope for.

But first, she had to get there. A task that was made incredibly difficult by the situation she found herself in. Any person she met might talk to her, and she had a sinking feeling in her gut that the most likely topic of conversation was the one she was specifically trying to avoid. Sweet Apple Acres wasn't exactly close to Carousel Boutique, either. She already had to make her way across town in order to make it back home without factoring in specifically taking the longest, most circuitous route possible in order to avoid people. Stick to the back-roads and alleys, avoiding anywhere she knew might be populated even slightly at this time of day. At several points she found herself having to hide for significant portions of time before making progress. A journey that should by all rights have taken her twenty minutes, half an hour tops instead lasted almost two hours – thank Celestia that, at the very least, the weather was good, or she might very well have considered giving up on the whole thing. As it was, she managed to get most of the way back to Sweet Apple Acres without encountering a single other pony.

It wasn't until she reached the outskirts of the farm that her plan started to fail.

The smell was faint, at first, but once she noticed it, it became impossible to ignore. Spicy and musky and unpleasantly familiar, announcing her presence like a herald announcing approaching royalty. She had noticed faint traces of it between the Boutique and the farm, but it was at its strongest, its freshest once she crossed the threshold onto Apple Family Property. Her heart sank further and further with every step she took, even as she held onto futile hope that she was mistaken. It could have been Big Mac, or any of their male farmhands sneaking off to the outskirts of the property to relieve some stress. As far as Bloom could tell, sex had become increasingly less taboo in Ponyville since this had all started, so it would hardly be surprising. She could almost believe it was the case, so long as she ignored the fact that no self-respecting stallion would choose anywhere near the one pathway into town for secret masturbation.

The smell of sex got stronger and stronger with each step she took towards the farmhouse. She knew exactly what she was going to encounter there, even as she tried to deny it or rationalize it away. With the way her day had been going, it wasn't even remotely surprising when she encountered Diamond Tiara waiting for her.

It wasn’t particularly surprising that Tiara had grown significantly since Apple Bloom last saw her. She already knew that much, thanks to Sweetie's dang poster. But the poster hardly did her justice; it adequately conveyed her height and the size of her endowments, but nothing could have prepared Bloom for the veritable brick wall that was the smell. It was very nearly overwhelming, sending her mind and body reeling like a punch to the face. She could only imagine how much worse it would be if she wasn't standing in the open air.

Unlike Sweetie's poster, Tiara's cock wasn't obscured by a living condom, allowing Bloom to take in its full glory. It wasn't unlike it had been when she'd last seen it in person, except bigger and better in every way. Tiara fondled it openly, using her free hand to molest her titanic bosom. Bloom could understand Sweetie's reverence towards even its likeness, and was sorely tempted herself to show it the respect it deserved. The only thing holding her back was her intellectual awareness that it absolutely didn't deserve any respect at all.

She noted that Big Mac and Applejack had no such reservations holding them back, quietly thanking Celestia that Granny Smith was conspicuously absent. Her two elder siblings were, unfortunately, completely nude. Each was on their knees, their upper bodies entwined around of Tiara's tree-trunk like legs like they were exceptionally large, muscular stripper poles. Applejack had her face nuzzled tightly into Tiara's ass, while Big Mac buried his in her prodigious balls, allowing her copious precum to run down onto him and thoroughly soak his fur through.

Bloom made a point of paying them no further attention beyond mentally acknowledging their presence. She had to look up, but glaring Tiara in the eye was preferable to seeing her siblings debasing themselves like that, mostly because it was kinda gross.

“I was almost worried that I'd have to go out and look for you,” she said, giving a fat nipple an idle pinch. She put in no effort to return Bloom's gaze, not even dignifying her by looking down on her. “I'm not going to ask for you to explain why you didn't show up to this year's Queen of Ponyville celebrations.” Bloom cringed even as the words were leaving Tiara's mouth. “Technically, no one is obligated to participate in them. Buuuut,” Tiara slowly lowered her gaze, grinning like a hungry shark. “You've still got to pay tribute at some point. Again, you don't have to do it now, but the longer you wait, the more you'll owe.” She licked her lips sensually, and removed her hand from her breast, holding it out to Bloom. “I figure that I can afford to be lenient, though. It is your first offence, after all. Just a blowjob and we'll call your debt paid. Sounds fair, no?”

Apple Bloom stood in silent shock for far longer than she was comfortable with herself doing. She didn't want to admit to seriously considering Tiara's offer, but it was difficult not to. Just being in her presence was enough to overwhelm her better judgement. She opened her mouth, then quietly closed it again, repeating the process several times, almost – almost – instinctively replying with a “yes, ma'am.” But no, she was an Apple, consarnit. If there was one thing that the Apple family was good at, it was stubborn refusal to compromise their principles. She wasn't going to do something she didn't want to do, even if she wanted to do it. “No,” she said, quietly and tentatively, after almost a full minute of silent staring at Tiara's outstretched hand.

“You'd rather wait, then? Well, that's fine, but like I said, the longer you wait, the more you owe.”

The smart thing to do would have been to wordlessly manoeuvre herself around Tiara and make her way to her room. Stick to the plan, not fight back – she had seen exactly what fighting back against Tiara resulted in. But, if there was one thing that the Apple family was good at, it was letting their stubborn refusal to compromise their principles dictate staggeringly poor decisions. “No,” she muttered under her breath.

“Excuse me?”

“I said I ain't payin' no stinkin' tribute to a spoiled brat with delusions of grandeur!” She snapped, letting all the frustration and anger that had been building up all day flow out. “I don't care how inexplicably hot you've suddenly become on the outside, you're still the same self-centred, egotistical cunt you've always been and I ain't lettin' you get the better 'a me!” She smacked Tiara's still outstretched hand out of the way and pushed past the huge bitch, fully intending to stick with the plan and lock herself up in her room for the rest of the day.

She didn't stop when Tiara let out a low, lusty moan. It wasn't until the ground lurched violently, knocking her completely off of her feet, that the gravity of exactly what she had just done dawned on her. She landed on her back, hard, knocking the air out of her lungs and leaving her with an excellent view of Tiara's ass. Tiara’s whole body was quivering and vibrating in time with the earthquake. Her arms slowly moved up and down as she pumped her mighty member, coaxing thick gouts of cum from it in rhythmic eruptions. Her moans increased in intensity and volume, building and building into unrestrained screams of rapturous pleasure.

And she grew.

During the arm wrestling matches, Tiara's growth had been barely noticeable until her clothing exploded. Bloom had only indirectly witnessed her growth at Sweetie's, but it had still only been a few feet. This time, though. This time Tiara grew decidedly more than a few feet. It was not slow, or subtle, though neither Applejack nor Big Mac seemed to notice it at all. They certainly weren't reacting, even as Tiara's legs thickened and lengthened, pulling them up off the ground and pushing their arms further and further apart. Nine feet became ten in a matter of seconds, and ten became fifteen not long after that. By the time Bloom managed to pull herself back to her feet, steadying herself on the porch, she just barely came up to above Tiara's kneecaps, and the growth showed no signs of slowing down. Bloom quickly found herself staring at Tiara's calves as she surged bigger and bigger, cock spewing a seemingly inexhaustible supply of musky, sticky cum all the while.

In the space of just over a minute, Tiara went from only a few feet taller than Bloom to towering over the entire farmhouse, to towering over even the biggest barn on the property. Her knees buckled beneath her, and she fell backwards into the gigantic, ornately decorated throne that had at some point come into being while Bloom was paying attention to her growth spurt. It loomed over Sweet Apple Acres, casting a vast shadow over the fields that stretched off into the distance. Tiara stretched her legs, each one dwarfing even the biggest tree in the Everfree, casting even more vast shadows over Apple Bloom. She let out a long, low groan of satisfaction as the last dregs of her orgasm finished. “Mmmmm, what was it you just called me? I'm sorry, but you're just so tiny that it's somewhat difficult to hear you! Correct me if I'm wrong, but I believe that your exact words were something along the lines of,” she paused, giving her chin a thoughtful rub. “Self-centred, egotistical cunt, was it?” She yawned, idly resuming her masturbation. Her voice was almost bored, containing no hints that she was even remotely upset by Bloom's outburst in spite of what she actually said. “I'll have you know that that's no way to refer to Prime Magistrate Diamond Tiara.”

Even as Tiara said it, Bloom could feel the memories flooding into her head from seemingly nowhere, standing right alongside the ones she knew were real. Prime Magistrate of all Equestria, second only to the Princesses themselves. “You should really watch your tongue,” she scolded, more like a mother scolding a mildly unruly child than the kind of reaction Bloom would have expected Tiara to have to being called a cunt. “Mmmm, I don't particularly want to, but first you refuse to pay proper tribute, and now you're hurling petty insults? You're simply going to have to be punished. Can't afford to play favourites in my position, after all. Unless you have something to say in your defence?”

Apple Bloom opened her mouth to reply, but no words came. All she could manage was a strained, dry noise, mouth opening and closing dumbly like a fish slowly suffocating outside of water. This was wrong. This was beyond wrong. There were no words that could adequately convey exactly how unbelievably, unfathomably, impossibly incorrect that every single minute detail about the situation she found herself in was. It was like a deep, personal insult to her specifically, moreso than anything before. Nothing she could say could adequately convey exactly how much Tiara could go fuck herself. Which, she realized with a sensation of sinking dread, was probably for the best. The results of her last attempt at resisting were staring her in the face, fifty feet tall and sitting on a solid gold throne built directly above her home.

“I'll take your silence as a no, then.” Tiara sighed, shaking her head chidingly. “Honestly, Apple Bloom, I wish you would just content yourself to just service me like everyone else does instead of always making such a production out of it. I know you like to play at resisting, but I have all of Equestria lined up to take their turn worshipping me. I simply don't have the time to give you the personal attention you want.” She reached down, picking up Apple Bloom like she was a doll, lifting her up and up and up until she found herself standing on the vast expanse of Tiara's palm, staring at a face as tall as she was.

At some point her clothing had ceased to exist, she realized with mild annoyance, as Tiara leaned in, knocking her flat onto her ass with her snout. She inhaled deeply, licking her lips. “Well, you may act like you don't want this, but you certainly smell eager enough~” she purred. Her words washed over Bloom like a hurricane, reeking of lilac and mint and bubblegum and sex. Her pussy twitched slightly in spite of herself, and she grunted with the effort it took not to writhe and squirm and moan and give in. “Mmmm, you smell goooood,” Tiara moaned. “Don't think anyone'd mind if I had a little sample before your punishment begins for real~” Tiara shoved her massive snout in between Bloom's legs and inhaled deeply. The force of her breath pulled Bloom's torso up, holding her tightly against Tiara's face.

Pushing back was reflexive. The panicked scream of “Get the fuck off of me you big whore!” was not. Bloom was uncertain which one was the trigger, but it hardly mattered. Knowing the cause wouldn't make the now unmistakeable wet rubbery stretching noises of Tiara's growth go away. She let out a low, rumbling moan as she dropped the hand that had previously been holding Apple Bloom to join its sibling in pumping her growing cock. Bloom instinctively grabbed onto Tiara's fur, clinging to her nose for dear life. She closed her eyes tightly, whimpering quietly. A mix of terror and need pumped adrenaline through her veins and filled her with unnatural stamina, which was the only thing keeping her from falling to her death. She couldn't see the growth this time, but she could feel her tightly gripping hands slowly pulling apart. Feel air rushing past her body, seemingly from every direction at once, hot and wet and musky. Tiara's breath reeked of sex, as did the air rushing downward from her growth. The atmosphere was so thoroughly saturated with Tiara's unrelenting sexuality that she could taste it, a salty, bitter musk. It felt like she was swimming in an ocean of cum. Tiara's cum. Now more than ever, holding on to lucidity was a herculean struggle. Every part of her screamed to give up, to give in. To let go. To accept her place in the new world order. Even as she struggled to resist, she could feel her mind being flooded by new memories. Memories of the new world order she found herself in.

She had no idea how long the growth lasted for. Time seemed to blur together into one infinite, exhausting moment as her hips rocked and grinded against Tiara, with no input from her conscious mind. She timidly opened an eye to take in what Tiara had become, and was rewarded with a vast expanse of pink, furry nose. It filled her field of vision briefly before a vast hand as big as she was gently plucked her like she was a prize in a crane game. Bloom felt herself being carried through the air, rendered completely and utterly helpless before the sheer size Tiara had become. All she could do was take in her surroundings. Sweet Apple Acres was gone, replaced by a cavernous palace. The ceiling was so distant that there was a faint mist slightly obscuring it from view – it had to be, Bloom supposed, or else Tiara wouldn't be able to fit in it. She was huge, at least twice the size she had been moments before. The throne had not only grown bigger, in order to accommodate her larger size, but more ornate. It shimmered, as though carved out of one gigantic diamond, inlaid with gold and silver and gems that formed murals of sexual debauchery along every single solitary square inch of chair. It was enormous enough that Bloom could pick out every little detail, even from as far away as she was. Certainly, they were more clearly visible than the other ponies in the throne room. Countless, barely visible specks of colour on the uncomfortably distant floor, and slightly larger specks littered across Tiara's vast form – including, Bloom realized with a sinking feeling, a pair of vague blotches of off-white and indigo that could only be Princess Celestia and Princess Luna, crawling over her divine tits like they were insects. Literally divine, as Bloom took in Tiara's brand new wings and horn.

“I am pleased to announce that Lady Diamond Tiara's glorious Holy Equestrian Empire now reaches as far south as Horsetrailia, Officially encapsulating over seventy five percent of the known world, with more countries submitting themselves to our superior might daily,” Silver Spoon loudly and joyfully announced from somewhere. Bloom wasn't quite sure exactly where, but clearly magic had to be involved for her to be audible at all. “Emissaries from the Gryphon Kingdoms are presently awaiting an audience with Her Grand Holiness, Empress Diamond Tiara, to negotiate the terms of joining the Empire.”

“Mmmm, tell them to come back later,” Tiara said, waving dismissively with her free hand. She yawned languidly, her eyes focused solely on Bloom. “I'm spending some quality time with my favourite pleasure pet, and she's presently in the mood to play hard to get~”

It took several moments for it to dawn on Bloom that Tiara was talking about her. She briefly opened her mouth to talk back, but snapped it shut before saying anything. Taking in the full scope of the results of her last attempt at mouthing off, as much as it had been entirely reflexive, perhaps it was better to say nothing at all.

“What's the matter, Pear Blossom? You were putting up so much of a fight earlier and now you're just sitting there like a little statue. What happened to all that fire, hm?” Her voice oozed with confident condescension. There was an unshakable, divine knowledge of her own perfection laced into every syllable. Her voice rumbled like an earthquake, washing over Apple Bloom's entire being down to her very soul. “Don't you know that's why you're my favourite slut? You try so hard to fight back against me, it's just adorable.”

That's what she was, in the end. In the new world order that her many futile attempts at fighting back had created, she was nothing more than a lowly slut who only existed to pleasure her mistress. And, as far as it mattered, that's all she'd ever been. Everything about the world reflected that immutable fact, that Tiara was superior and she was inferior. Even her body had changed. Gone was the powerful, rippling musculature that had been the result of more than a decade of heavy labour on the farm. There was still muscle, she had to be strong in order to be able to climb Mistress Tiara's body, to properly pleasure her goddess, but it was buried deep beneath a plush layer of luxurious fat. Her breasts bulged against the micro-bikini top she found herself wearing, clearly several sizes too small, especially considering that her breasts had grown significantly. It covered exactly her nipples and nothing else, not even areolas, in flimsy fabric the same dark pink her old bow had been. A matching thong, barely big enough to actually cover any relevant parts, dug tightly and almost uncomfortably into newly fertile hips and soft assflesh. Her belly bulged outwards and over it in a way that it never had before, and that it always had. It wasn't quite enough that she counted as fat, and either way it hardly made much of a difference when compared to how vast Tiara had become – so large that any building large enough to house her developed its own weather systems. But still, it rubbed salt in the wounds to be that much worse than Tiara, however slight it might be.

And yet, at the same time, this was how things were supposed to be. It was wrong, but it was right. This was new and different, but it was how everything had always been. Her mind was at war, with half of her mind telling her that Tiara had grown and that mere days ago she had been barely over four feet, and the other half painting an equally vivid picture of how the way things were now was the way things had been her entire life and would be forevermore. If not more vivid. She could feel her memories of her old life slowly fading away, and even though she knew for certain they were the truth, there was a part of her that wasn't so sure that they weren't just an elaborate fantasy her mind had constructed to motivate her to better pleasure Mistress Tiara.

Of course, in the end, it hardly mattered. If things had always been this way, fighting back too much would eventually make Mistress Tiara angry. And if her fantasy was the truth, then fighting back would just make Mistress Tiara bigger. And, in spite of the erotic tingle that sent down her spine, she didn't want that. It was already so difficult for her to draw any kind of pleasure from her goddess, as tiny as she was compared to the divine body of Mistress Tiara. Making her bigger would make her job downright impossible.

“But Mistress,” she said, her voice meek and tentative. That, on its own, was enough to shake the doubt from her mind. The Apple Bloom from this reality would never be so uncertain. No, she was not an experienced pleasure pet. She was just Apple Bloom, the big dumb farmgirl. “If I keep on resisting you, eventually it'll get old. I thought I'd shake it up by being a bit submissive for a change.”

“Mmm, clever girl.” A gigantic finger, bigger than Apple Bloom's entire body, slowly reached down and ever-so-gently patted her head. “Such a good little girl, always thinking of her Mistress,” she cooed. The praise sent an uncomfortable warmth welling up deep in the core of Apple Bloom's being, and she squirmed uncomfortably.

“Thank you, Mistress.” She'd tried resisting, over and over again, and it had always backfired. The only thing Bloom could think of to do now was to try playing along. There was no way Tiara could grow if she didn't resist, even passively. She would do her absolute best to pleasure her until all of this went away.

“No need to thank me. Good pets get rewarded with praise and scritches and fucks. You've gotten your praise, and your skritches.” Once again, Bloom felt air rushing against her body as Tiara moved her in close, inches away from her mouth. “Now,” she opened her vast maw, wider and wider. Her teeth, perfect and white and so very big, glistened with moisture. Thin strands of shimmering drool connected them as her tongue slowly emerged. It was enormous, bigger than Bloom's entire body and more. Bright red, with a rough and bumpy surface that trapped glistening pockets of saliva. Hot, wet, musky air rushed over her body once again as Tiara slowly licked her, starting from the bottom and slowly working her way upwards. It lingered on her crotch, pressing firmly against the inadequate fabric hiding her moist cunny from the warm air of the palace, wriggling up and down and left and right and up and down and left and right, drawing a strained groan of orgasm from Bloom. Satisfied, Tiara continued her journey upwards, pausing again at Bloom's tits. The giant muscle played with them gently, before quickly finishing its canvassing of Bloom's front. “For the fucks~”

There was the rush of movement again, pausing with her dangling just above the landscape that was Tiara's lavender flare. Slick, translucent pre bubbled up from her urethra hundreds of gallons at a time. “Look how big I've gotten. Big and leaky, all because you're such a big whore. Oh, but even though you're getting rewarded for being such a good girl, you still need to be punished. Don't think Mistress Tiara's forgotten about that. You don't get to have aaaaany of this until then. No, what you get is to spend some time thinking about where you belong-”

One final time, there was a rush of movement as she found herself dropping down down down down, until - “While I put you in your proper place.” Tiara's free hand hefted her enormous ballsack. Each churning cum factory was bigger than the farmhouse had been, by several orders of magnitude. Tiara placed Bloom gently in the shadow of her virile testicles. “I think half an hour would be an adequate punishment for you, no?”

A terrible, terrible thought blossomed in Apple Bloom's mind. It was only the faintest glimmer of an idea, but it was an idea that filled Bloom with an unfathomable dread almost enough to overwhelm the overpowering desire she felt. Oh, she wanted this so badly. To be flattened, buried under countless tonnes of Diamond Tiara's manly cumsacks, overwhelmed by musk forever and ever. But she could not shake that faint, nagging feeling in the back of her head. There was something, some vague and nebulous but unshakable sensation that somehow, this was going to go wrong, even as she lay down as flat as she could. After all, if she stood up, there was the chance that she might get hurt when the balls came crashing down on top of her, burying her, suffocating her, no matter how hard she fought-

The realization hit her like a tonne of bricks immediately before considerably more than a tonne of balls did the same. She just barely had the chance to scream, “Wait, don't-” before her world was nothing but hot, musky, infinite darkness. It was suffocating, no air except that which managed to filter under Tiara's balls, saturated with the stench of sex, of cum, of virility. They surrounded her almost completely, conforming to her body like a glove. She could feel herself sinking in deeply. Pressing onto her.

Or, rather, her body was pressing into them.

Against them.

They began to undulate, pulsing and rumbling and swelling, churning audibly as they produced more and more and more cum, almost but not quite drowning out that uncomfortably familiar rubbery noise.

Apple Bloom had no choice in the matter but to resist. She couldn't not resist if she fucking tried.

She could feel that vague apprehension building and building into a panicky crescendo. Her body moved on its own even as her mind screamed at it to stop, that this would only make it worse, but she couldn't help it. It was a reflex of a body that was afraid it was going to die, crushed to death by tonne upon tonne upon motherfucking tonne of hot, musky cumsack. She struggled and squirmed, even as darkness slowly creeped its way into the edges of her vision, spreading like oil as unconsciousness slowly enveloped her almost as tightly as Tiara's testicles.

Apple Bloom had no idea how much time passed between blacking out and regaining consciousness. All she knew was that she was no longer in the throne room, and no longer being crushed to death by ballsack. It was far too dark to see where she was, but she was at least free. The air was hot and moist and musky, even moreso than the throne room had been – even moreso than Tiara's balls had been. Like all of Equestria was completely suffused, saturated with Tiara's manly essence. The ground felt soft and wet, and smelled even more strongly of sex than the air. All around her were enormous shapes that she assumed were trees. She couldn't think of anything else they might be, but it was too dark to know for sure. She pushed her way forward, shoving aside the thick foliage as best as she could as she began her journey to escape the wilderness she found herself trapped in. She'd lived next to the Everfree forest for long enough that she knew the best course of action was to just pick a direction and walk in a straight line until she saw sunlight.

The trek was difficult. The trees were flexible enough that she could just barely push her way through, but they were thick, contributing to the disorienting atmosphere along with the rumbling of the uneven ground beneath her feet. It occasionally lurched and pulsed like an earthquake. Or, more likely, a distant Tiara pleasuring herself. It took what felt like hours before the trees began to thin out, light began to filter in through the canopy, and Bloom realized with a sinking feeling that they were not trees at all.

Before her, dark purple ground stretched off into the horizon. It glistened and pulsed and reeked of sex. The sun was setting in the distance, nestled between two massive pink mountains, the same pink as the forest behind her, that Bloom could barely make out, each one capped with an engorged, leaky nipple.

“Ah, there you are, Bloom!” Tiara's voice boomed, coming from everywhere at once. It resonated through to the core of Bloom's being, less a voice and more some kind of force of nature. Like if an earthquake or a volcano or a hurricane could speak. Like if an entire fucking continent had a voice, this is what it would sound like. “I was, mnnn, worried for a moment that you'd gotten yourself hurt!” The ground rumbled in time with every word she spoke. Apple Bloom struggled to maintain her footing, and failed miserably, falling flat on her newly fat ass.

“You're supposed to evacuate well in advance, silly!” She giggled. “Now you're too late! I've already cum once an– mnnnnnngggg – and it'll be a few weeks before I'm done. And that's if you're lucky, because I've been cumming so much more lately.” The ground lurched and rumbled violently beneath Bloom, even when Tiara wasn't speaking. Her voice was underscored by a deep, wet noise – the sound of her country-sized balls producing more and more and more. “I think this time I might even be able to break my record! I've grown a few hundred miles since I set that one, so I should hope I'd be able to break it!”

Apple Bloom swallowed heavily as she felt the ground – the cockflesh beneath her begin to slowly rise. “What- what was the old record again, Mistress?” she asked tentatively, her voice far too quiet for Diamond Tiara to even possibly hear.

“A year and a half. Let's shoot for three, shall we? Ooooooooooooh fuuuuuuuuuckkkkkkk, here I cuuuuuuuuuummmmmmm!” There was a deafening crash, the sound of Tiara's hips rising and crashing down with literal earth-shattering force. Again, and again, and again she thrust. Bloom flung herself flat on her belly, grasping tightly to Tiara's skin. The size difference was so impossibly vast that Bloom couldn't even see the orgasm happening, not this close. All she knew was that the ground beneath her was rushing upwards, miles upon miles as countless oceans' worth of cum rushed forwards at once. Oh, but she could picture it so clearly. Gigantic fingers, each one miles across, digging gashes in the earth below her so deep and wide and long they made even the biggest, deepest of canyons look insignificant. Her ass, so fucking massive it stretched all the way from Baltimare to Los Pegasus, rose and rose and rose, hundreds of miles in the air, before crashing down to earth with such force the continent below her shattered. Gouts of fire and lava erupted forth from the cracks as Diamond Tiara literally humped the world to oblivion.

What finally pushed Bloom over the edge, though, was what she could see: Diamond Tiara's breasts, bigger than the biggest mountains. Heaving and swaying pendulously, capped with big, leaky nipples the size of cities. She could just barely make them out in the distance, erupting like volcanoes, spewing out enough thick, fatty milk to end world hunger forever. Titanic hands squeezed and groped at them, pushing them ever so tightly around her continental shaft, working it up and down as she came and came and came with no end in sight.

Tears of joy ran down Bloom's face. This was it. What everything, the entire time she had known Tiara, her entire goddamned life had been building towards. This single, perfect moment. This was her purpose in life – to aid in Diamond Tiara's ascension. To facilitate this new world order, the way it was always meant to be. This was where she belonged. Less than an ant compared to her Mistress, her Goddess.

She had already flung her body about as low as it could go, but somehow she managed to press herself lower. Closer to the musky flesh of Tiara's Divine cock. She spread her limbs widely, rubbing herself up and down against it as best she was capable of. She wasn't big, not nearly big enough to even be noticed by Mistress Tiara, but any pleasure she could bring, no matter how slight, was worth it. It was her role. To make Lady Tiara bigger and to make her feel good.

“Oh, Lady Tiara,” she moaned. “Oh, Lady Tiara, you're so good and I'm so worthless. You're better than me, in every way, and-”

There was a lurching feeling, deep in the pit of Bloom's stomach, as reality rewrote itself one last time. It was like a badly done jump cut in a low-budget movie. One moment she was giving a full body massage to a cock the size of a continent. The next, everything was back to normal. She no longer had the body of a pleasure slave, perfect for pleasuring her perfect goddess. She was no longer wearing a slutty slave girl bikini, instead just the normal overalls and tank top that hadn’t fit her burly frame in ages.

She was at school, at the end of the day. “Are you listening to me, Apple?” Tiara was standing before her. She was no longer a living goddess, once again just barely over four feet tall. “I don't care about my fur, it's gone back to normal, but you ruined that dress! It cost me almost three thousand bits, you fucking asshole!” She was lunging at Bloom viciously, or at least attempting to. Silver Spoon stood behind her, awkwardly holding her back from ineffectually attempting to maul Apple Bloom. She gave the taller mare a pained look, and silently mouthed “I thought it was funny, honest.”

“Well?!” Tiara shouted, bordering on frothing at the mouth. “Are you just gonna stand there like a retard or do you have something to say for yourself?”

It took Bloom a moment to collect herself. The tonal whiplash hit her almost as hard as Tiara's balls had. And she was still so fucking horny. She'd spent the entire day resisting Diamond Tiara, until the very last second. And, when she'd finally admitted to her true feelings and given herself over to pleasuring her mistress, it had all ended before she'd gotten any kind of proper release. It was difficult to think straight. It was difficult to think at all. All she could do was give over to instinct.

Instinct currently was telling her that she had angered her Goddess. She dropped down to the ground, prostrating herself before Lady Tiara like a worshipper before the Divine Being made flesh that she was. “I'm so, so, sorry, Mistress Tiara. It won't happen again, I assure you, and I'm willing to accept whatever punishment you deem necessary for such a transgression from a lowly slave like myself. Use me and abuse me however you see fit, I deserve it for daring to defy your divinity.”

There was a good minute of silence. “Uh.” Tiara stared down in blank confusion at the worshipping Apple Bloom. “Are... Are you making fun of me?” It certainly made more sense than her doing this sincerely, but if that was the case then Bloom was a much better actress than she'd ever given her credit for. No one, not Tiara, not Silver Spoon, not the small crowd that had gathered to watch the small spectacle unfold, no one had any idea how to react to this.

After a moment, Tiara frowned. “Fine, whatever. Fuck you, can't even be bothered to just say 'oh I'm sorry for wrecking your expensive outfit' like a normal person. Cunt.” With that, she turned and stormed off, dragging a snickering Silver Spoon behind her. “Don't fucking encourage her, Silver. This isn't funny.”

Apple Bloom pushed herself to her feet, and watched Mistress Tiara leave. She was no longer even the nine foot tall sex goddess, let alone massive enough to be beyond measurement. But at least, Bloom noted, she still had a nice enough ass. She was a bit scrawny, but her butt was still nice and firm and perky, rocking enticingly as she walked away. Still, it hardly compared to how she had been. How she should be.

No, this wouldn't do at all, she decided. Mistress Tiara was far too small. She smacked a fist into a waiting hand, making a meaty noise as she resolved to make things right. She turned and marched off towards the Library. That was her first stop, to pick up as many books on alchemy – and, more importantly, formulas and recipes for growth potions, fertility and virility enhancers, and other sundry ways to help Mistress Tiara reach her proper place in the world as she could carry. And, from there, directly to Zecora's hut to get to brewing, and perhaps get some advice and further recipes and formulas for growth potions from her. Getting there from the library, of course, would be something of a trek, and she would have to go through the Everfree, but that was fine.

She knew a shortcut.
