"Silver! Open up! I've got something awesome to show you!"

“Ngh, go… go ‘way.” Silver groaned and buried herself deeper in the covers, barely daring to check the clock. Whatever terrible dream she was having right now, it was being too loud.

“Silver, if you don’t get up and come here immediately, daddy might just happen to find out about you-know-what.”

That got Silver’s attention. She bolted up, barely pausing to rub the sleep out of her eyes before she put her glasses on. “C-coming!” she shouted, trying to find her slippers. “I’ll be right there!”

The strangeness of the situation only demanded further haste. Diamond Tiara wasn't one to get exceptionally excited over nothing. She prided herself - often - on her levelheadedness. Calm, cool, collected. Smart. So her banging on the door to Silver's room, squealing with barely contained excitement, was incredibly unusual. Doubly so this early in the day - the sun wasn’t even remotely risen yet.

The banging only grew louder and more insistent as Silver bolted to the door, a proper mess without her usual morning grooming. Her mane, typically brushed and braided to perfection, was an unruly bird’s nest, and she’d have preferred to die before going out in her ducky pajamas - but she could never afford to keep Diamond waiting. Morning or not, anything Diamond wanted demanded the utmost haste.

...Not because Diamond deserved it, or anything like that, but because it was always much easier to do things her way than to argue about it. Diamond was more stubborn by half, and had much better vocal chords for shouting. Plus a full head's worth of height on her. No sort of argument would ever end with Silver Spoon as the victor, so it was simply much less of a headache to play the submissive.

She let out the yawn she’d had brewing before opening the door, apologizing for her lateness with a quick bow. "Yes, Diamond?"

Behind the door, Silver found a manic, grinning Tiara. Something was different - it had to be, or she wouldn't have up nearly this early. Diamond’s normal waking hours started somewhere around noon, if not later. And yet, here she was, at five in the morning, grabbing Silver by the arm and dragging her off to wherever it was that they were going? Silver didn't really know. All she knew was that Diamond Tiara hadn't bothered to put on any real clothing herself. She was only wearing a translucent pink nightie, underneath which were a lacy white set of lingerie, snug and slightly too small for her. The straps dug tantalizingly into her abundantly soft, supple flesh, and Silver couldn't help but steal a glance or two while they were on the move.

"Here we are!" They arrived outside of Tiara's bedroom - Silver had been rooming in Tiara's home in lieu of getting her own place. It was cheaper, and the sex was decidedly not a deterrent either. "It finally came! I spent all last night setting it up and - aaaah, I just can't wait to try it out!" Tiara grinned, bouncing with barely contained glee (which, Silver couldn’t help but notice, had the delightful side effect of sending her ample feminine curves jiggling).

"You can't, um..." Silver trailed off as her eyes zeroed in on Diamond's ample body. It was hard not to, especially with the way her physical expressions of excitement set it in delicious motion. Diamond had always been the taller of the pair, and after puberty she'd easily asserted her place as the bustier and the curvier, too. And it wasn't just next to herself, either. Even stacked next to Apple Bloom's height, Sweetie Belle's bust, and Scootaloo's lean, fit physique, Diamond Tiara compared favorably in all categories.

"Can't wait to try what out?" Silver Spoon finally finished her train of thought, blushing slightly. If nothing else, the view was certainly a nice perk of their friendship. “Did you order something?”

"Oh, didn't I tell you about it?" Diamond gave Silver an exaggerated wink. She flung open the door to her room, revealing...

...a scale model of Ponyville? It was obviously smaller than the real thing, but it was still massive by anypony’s standards, taking up most of the available floorspace in Diamond’s room. And Diamond's room was nearly larger than the whole Ponyville schoolhouse. The replica itself was clearly painstakingly accurate - Silver could tell even from a distance that hours and hours of effort had gone into making the perfect replica of her hometown. From the craggy peaks of Canterlot mountain to the frosted architecture of Sugarcube Corner, it seemed accurate in every possible dimension. Getting closer to it brought more and more details to light. Here, a street sign Scootaloo had knocked over ages ago that had never quite stood perfectly upright since. There, the weathered paint on the Sweet Apple Acres farmhouse, peeling away in exactly the places Silver remembered, albeit in miniature.

"So," Tiara said, grinning so widely her head was in danger of falling off. "What do you think?"

"Um..." Silver yawned, still working off her exhaustion. It was a nice model, to be sure. A fantastic model, even. Silver’s mind boggled considering how much time and effort must have been poured into making it. But, at the same time, it was certainly nothing to get this excited about. In fact it looked a bit like those model playsets Diamond had always obsessed over when they'd been much... younger. She cocked an eyebrow at Diamond, trying not to look too judgmental. "It's nice," she said, to start things off. "But, Diamond, don't you think we're... um... just a bit too... old? To still be playing with toys?"

"Please, Silver,” Tiara waved dismissively. “If my father can spend hundreds of thousands of bits on scale models of Baltimare and Manehattan and whatever for his dinky little toy trains without anyone judging him, I don't see why I can't do the same." Her facial expression morphed slightly. Less gleeful and more... lascivious? Was that the right word? There was definitely a predatory aspect to that smirk she had on. "Besides, this isn't just any old playset. It's enchanted."

Enchanted! Silver's ears perked. Diamond's idea of an enchantment was usually fun, when it was for the bedroom and not a mean-spirited prank. She took a glance back at Diamond, supple, palm-filling breasts still jiggling beneath her nightie as she bounced from hoof to hoof.
"I guess that makes it better," Silver murmured. She reached out a hand, almost as if to touch one of the little buildings, but thought better of it at the last minute. Best not to play with magic she didn't understand just yet. "But enchanted how?"

"Oh, you can probably guess," Tiara purred, twirling a lock of lavender hair idly around an index finger. "It's actually designed for foals, but I had some... special modifications made to it. Removed some limitations designed to keep things foal-safe~ It was expensive, of course, but it's all on Daddy's wallet. You know how he is! Anything to please his little princess~ Suffice to say," her grin widened, even more predatory than before, "you're going to like it. I promise."

“Well..." With that hint, she probably could guess what the enchantment was, now. Silver had read about something like this before: miniature landscapes that foals could enter and manipulate to act out their imaginations. There were usually safeguards, though, that kept anything too sexy or inappropriate from happening. Safeguards that Diamond had undoubtedly removed. Silver bit her lip, mind racing with all the possibilities that total control over a little Ponyville made for. The both of them goddesses, acting out all their wildest fantasies in a world they both-

"Wait..." Then she remembered something else about playsets like these, and her heart suddenly sank. Any number of ponies could take part in whatever world the playset's Owner created, but... "Diamond, isn't only one pony allowed to be the Owner?"

Tiara rolled her eyes. "Yeah, so? The way I see it, that just makes it more fun!" She leaned in close, having to duck down slightly in order to get to her desired position, her face almost buried into Silver's ear. "Think about it," she purred sensually, sending a shiver down Silver’s spine. "You, alone in Ponyville, at the mercy of my every whim. Every kinky, dirty, filthy little idea that pops into my head becoming a delicious reality~" She gave Silver's ear a gentle nibble. "And I do mean anything. What with the modifications I had done, the limits I had removed, the only limitation is my imagination. And I'm a very imaginative pony when it comes to sex, Silvy~"

And then, just like that, she pulled back. "In short, don't be such a wet blanket, babe. Just go with the flow and let's fuck like animals." Without a further word, she grabbed Silver and flung her forward into the playset, laughing as she jumped in gleefully after.

"Ughhhhh." Diamond Tiara had the worst fucking hangover. She glared angrily at the sun, flittering its way into her bedroom through one of her massive windows. "Fuck off, sun," she muttered. "Motherfuckin'..." She stretched and scratched herself idly as she got out of bed. Slowly and deliberately. She looked at the time - 9 AM. Celestia's tits, it was way too fucking early to be awake. She shed her blankets and groggily left her bed to get dressed and grab some coffee.

She wasn't wearing any clothing, she’d noticed. That was… odd. She definitely remembered wearing actual bedware - her transparent pink nightie and the lacy white undies that she’d specifically bought a hair too small because she knew that it drove Silver fucking wild. Silver's favorites. She couldn't quite remember why she'd been wearing them, though. Something about... a surprise? It couldn't just have been an early morning quickie. She reserved that outfit for special occasions.

“Hm.” Her sleep-addled mind dimly recalled something to do with a playset? But there was no playset in her room. It hadn't arrived yet. Oh, yes, okay. That was it. She'd only dreamed that it had come in, and woken up just before she’d gotten to the good bit. She nodded knowingly, flinging open the doors to her enormous walk-in closet as a cloud passed over the sun, the light dulling slightly. She grabbed something at random - just for the sake of having something on. A keyhole sweater that she didn't remember owning. Dimly, she recalled Silver begging her to get one of those, but it had never really been Silver’s place to dictate her wardrobe. She shrugged and slipped the thing on anyway. Whatever, as long as it fit.

"Coffee! Three sugars, extra cream!" she shouted to the servants downstairs. The usual chorus of affirmation was strangely absent, but some days the servants were just quiet. It wasn't her business to control their volume, as long as they got the job done… Though, speaking of that... "And it had better be hot by the time I get downstairs!" she added.

Orders given, she dipped into the bathroom to freshen up. The morning routine went without incident: manestyling, brushing, and all that. She paused only briefly while measuring out the toothpaste for her toothbrush. The tube was the customary red of her usual Cinnamon Blaze, but she could have sworn she'd stolen Silver's tube of Minty Blue just last night when she'd run out... Diamond shrugged. Not her problem either.

What was her problem, though, was that none of the servants had her coffee waiting for when she got downstairs. In fact, none of the servants seemed to be anywhere at all.

"Ugh." Diamond groaned and stepped into the kitchen to put the coffee on. Useless, useless, useless. It was probably one of those worker holidays the servants always thought they were owed. What pains in the neck. And where in Celestia's name was Silver Spoon? Even she'd gone absent without getting the coffee ready for her! "Double ugh," Diamond grumbled. She'd be giving Silver an earful for that later.

Tiara grumbled all the way to the kitchen. She preferred not to make her own coffee this early in the morning, but given the choice between going without and making it herself, she had to pick the latter. It wasn't like making coffee herself was difficult - she had spent several thousand of daddy’s bits on a very fancy cappuccino machine. No muss, no fuss, just press a button and get coffee. She'd gotten herself coffee before, but for the first cup there were several more steps - add fresh water, add fresh beans, run a cleaning cycle. More steps than she was usually willing to put up with. But put up with them she did, muttering vague promises of righteous vengeance under her breath all the while.

It took her ten minutes to get her morning coffee. Ten minutes that thoroughly soured her mood. "Fuckin'..." she growled. "Where is everypony?" Diamond took a drink of her freshly brewed, piping hot coffee, scratching her bare ass - she hadn't bothered to grab any bottoms. Or underwear. Or anything other than the tight keyhole sweater. It was long enough to mostly cover anything that could get her in legal trouble if she poked her head outside for whatever reason. For example, to see where the fuck everyone had gone. "Silver!" No response. "Daddy!" No response. "...Mother?"

Nothing. No one responded. It wasn't surprising that any one of her housemates would be out, but all of them? At the same time? This early in the morning? No, she thought, frowning and shaking her head. This wasn’t normal. "Where the fuck did they even go?" She stormed off, making her way through the dimly lit manor she called home. That was also somewhat odd. It had been bright and sunny outside when she woke up, but then that cloud had passed across the sun and since then the light had gone dim and dull. If anything, the sky had only gotten darker since waking. It felt more like evening than morning.

She reached the front door, threw back the rest of her coffee, threw the cup over her shoulder (she could always get a new mug, and breaking this one was delightfully cathartic), and threw open the door.

...To find no one. Not a single pony milling around in the darkened town. "Maybe it is a worker's holiday or some bullshit like that," she muttered. "I guess that's why no one's around?" It was definitely going to storm. It was apparently overcast, and the air was hot and wet, in that way that the air only got immediately before a massive thunderstorm. Tiara groaned loudly. "It'd better not be about to rain," she muttered. "Because I'm not making my own food and if I can't at least get to a restaurant I'm going to murder someone. And that goes double if they’re all closed!" she shouted, as if one of the absent ponies might overhear her irritation and make certain that there would be somewhere for her to get lunch. She glared at the empty town, as if the force of her irritation could change the weather. It didn't, so she turned her focus upwards, to the presumably angry, dark clouds above her.

And then she noticed that there wasn't a cloud in the sky.

"...What the fuck?"

Something was definitely wrong. She turned her gaze further up, and up, and up, scanning the sky for whatever was blocking the sun.

And then she saw the cause.

"Oh."

There, far above in the sky, were the two biggest tits she'd ever laid eyes on. Not in a hyperbolic sense - they were beyond massive. Mountainous, sun-eclipsing knockers topped with nipples that had to be the size of a poorer pony's house. She let her eyes wander back to their owner, over the all-encompassing wall of dark gray fur that had risen behind her mansion. Her vision trailed down a smooth gray stomach big enough to build another Ponyville on, down and down and down... Until her eyes met a fat, pink-lipped pussy looming like a monster over her house. It looked nearly big enough to swallow the mansion whole, clit throbbing happily as it pressed ever so slightly against the very tallest towers. Diamond's nostrils flared as she realized the air wasn't just hot and humid. The atmosphere was thick with a musky, nigh-on overwhelming haze of arousal.

"Hey, Diamond!" rumbled Silver Spoon's voice, times a million. She giggled, and the ground shook unsteadily beneath Diamond's hooves. "You're a late riser, aren't you? I got so bored of waiting that I decided to play around a little. See how big I could get." Again, that earth-shaking giggle. The tallest tower of Diamond's mansion buckled, almost ready to tip over as Silver's clit rocked ever so slightly against it. "But being the size of the playset's universe got a little boring, so I settled on big enough to straddle the town. What do you think?"

“What do I…? Ugh, I see what happened." Tiara pinched the bridge of her nose. "I forgot to designate myself as the Owner before we jumped in, so somehow it defaulted to you. Great." She groaned. "Well, it's an easy fix. We're just gonna have to start the whole thing over. Irritating, but whatever." She took a deep breath, and immediately regretted it, her nostrils filling with Silver’s burning sexual musk. Instantly, she felt overly warm. Hot. She could feel herself panting as her body was enveloped in intense, burning lust. "Silver, get back to normal, you're making me horny and it's too early for foreplay. We need to get out of here so we can do this right."

"Mm..." A titanic finger dipped down to earth, brushing itself gently over her clit. A warm, gooey feeling rose around Diamond's hooves, and she yelped as she realized she was standing in a rising tide of Silver's arousal. "Nah, not really feeling it. C’mon, let’s actually have some fun first! You said it yourself, Diamond, it'll be sexy!"

A second Silver Spoon, smaller than the first but still titanic next to Diamond - easily twice the size of her mansion - peeked her head over Silver's wall-like thigh. "Plus, look how cute you are!" She grinned as she scooped Diamond up like a grain of rice… along with a generous helping of the first Silver’s juices. "You know, I always thought you'd look great in a keyhole sweater."

"Silver, this isn't funny," Tiara snapped, blushing deeply. Her sweater suddenly felt warm and wet as the fibers soaked up Silver’s copious arousal. She wrinkled her snout, trying to focus on breathing through her mouth instead to avoid inhaling any more of that delicious musk. "We can have plenty of fun when I'm in charge like I’m supposed to be. Now, put me down and let's just-" she suppressed a groan, subconsciously rubbing her thick, feminine thighs together. "Let's just go home, okay? And do this right?"

The two Silvers giggled in tandem. The larger one rocked her hips ever so slightly forward, lips pressing gently, but insistently on the back of Diamond's mansion. Though she knew it was only a magical recreation of her real home, Diamond couldn't help but wince at the idea of her best friend using it as a makeshift dildo... nor could she help blushing, her thighs clamped together as the image made her even hotter.

"I don't think it's a good idea to go home just yet, Diamond," the smaller Silver said, as casually as if she were discussing the weather. She swung her hand over toward the mansion, giving Diamond a full view of her larger self’s ever more insistent motions. Stone walls built to last a thousand years were already beginning to crack and crumble for Silver’s pleasure. "You might need to get a few repairs done first, once I'm done with it. You know how I can get sometimes." She giggled as she dipped a finger into her palm, sticking the juice-soaked Diamond against the pad. "And I know you, Diamond, so I know when you're playing hard to get. I can practically smell how turned on you are, and you're quite literally swimming in how turned on I am right now. Let's play a little."

Tiara frowned. Playing hard to get?! "Silver," she growled through clenched teeth. "We are going to leave the playset. And then we're going to go back in, with me as the Owner. And then we can play all you want. To your heart's fucking content." She turned away, crossing her arms and closing her eyes. "And until then I refuse to play along with this charade."

It took far more willpower than Tiara was comfortable admitting to resist Silver's offer. Between the two of her, and a little of Diamond herself, the air was completely saturated with intense sexual musk. It was overwhelming and mind-numbing. It was all Diamond could do to not give in to the enormous mares’ demands. Give herself over to raw desire. It wasn’t like she’d never fantasized about being the bottom before. There was something tantalizing about being so completely overwhelmed, enveloped in sex with no option or opportunity to object. No, it wasn’t the situation that Tiara objected to. It was the way that it had come about. There was a world of difference between Tiara giving herself and Silver taking her the way she was. Something about it made her afraid, a deep, primal kind of fear.

And something about that fear made the tingles running down her spine all the more intense.

"Stubborn, aren't we?" Silver winked, with an eyeball bigger than a dozen Diamond Tiaras put together. "I see how it is! Don't worry, Diamond, I think you're going to like this game of ours. And it's only fair! You always get to make the rules. Maybe you'll like it more, letting me take-"

The world seemed to pop. Suddenly, Diamond found herself not precariously suspended hundreds of feet in the air, but sitting safely on a carpeted floor... in some awfully revealing corporate attire. The skirt was so short it couldn't possibly be decent, and the neckline cut almost too low for her comfort. Silently, she could only thank her lucky stars that she was dry and not sticky... though she blushed at the results of a quick sniff test. The faint scent of Silver Spoon was still clinging to her fur.

"-charge," Silver said, seated at the chief executive's desk. She seemed a bit more modestly dressed, in a smart black work jacket and matching pants, but something about her seemed too big by far. Sitting down, she was nearly eye level with Diamond, the fabric of her outfit stretched near to bursting with her seven-foot frame. "Now, Miss Tiara, I believe you had the earnings reports for the quarter?"
