The Be(hind) all and End all
Three weeks of planning. Three weeks!
A new brand of jeans was taking Equestria by storm. Discord had managed to gain access to the main source of production, and was ready to surreptitiously begin inserting his own addition to the design. An incredibly potent Want It, Need It spell that would make the jeans irresistible and essentially mentally incapacitate anyone who came into contact with a pair with their desire to own and wear them, eventually making the entire Equestrian population pliant and compliant. Discord had seen the power of this spell when Twilight inadvertently exposed Ponyville to it in the past, and it had given him this devilish idea.
He had the perfect idea to rapidly propel the circulation of enchanted jeans. An idea that would almost certainly make the jeans appeal to the Princess of Friendship, Twilight Sparkle, and not long after that her other royal friends. Twilight's close friend, Applejack, would be the perfect model to get the brand off the ground in Ponyville. She already wore jeans quite often and looked damn good in them with her large, curvaceous behind, wide hips and juicy thighs - the perfect model to lust after, and to make people lust after the jeans outlining every contour of her delightful curves.
Three weeks of labour had seen Discord create the super-enhanced spell, and bind it into the fabric of the jeans. Now, all he had to do was see Applejack at the meeting they had arranged a few days prior, and let Applejack try on the prototype.
"Mighty fine-lookin' threads, I'd say."
Applejack was very enthusiastic. A nice, new pair of high-quality jeans was something she wouldn't turn down easily. She'd worn a pair of her work jeans here. Despite also being made of denim, they were worlds apart from the fine specimen Discord had laid out on her kitchen table. The pristine stitching, the deep, ocean-like blue dye: true quality. Discord smiled.
"I'm glad you think so. Feel free to try them on - in your own time."
He smiled and turned, stepping out into the living room and sipping the apple juice his host had given him. Applejack eyed them up a little doubtfully, and looked over her shoulder and her butt.
"Sure hope I can squeeze into 'em, I ain't a small girl."
She discarded her own worn jeans, and stepped into the new ones. She began to hike them up, struggling a little with her thick thighs. Then she reached the big, round curve of her ass. Her toned arms flexed as she strained to pack her fat booty into the denim. With gritted teeth, a loud grunt and a very hard tug, the jeans gave up with a loud tearing. The material on the inside of her big thighs had torn open, as well as on the outside of the wide expanse of her hips. The spell, painstakingly and intricately woven into the material, was an integral part of the structure of the jeans. Now they were comprised, the enchantment lost its fine-tuned and delicate stability and broke up. A dark purple foggy haze spilled from the jeans and rose up, dissipating into nothing.
Discord heard the rip and stepped quickly back in, only to see his weeks of work quite literally go up in smoke. Applejack was a little confused.
"Uh, somethin' came out of 'em, mister Discord. I guess that stuff was important?"
Discord's eyebrow twitched, and he struggled to hide his apocalyptic scowl.
"Applejack, my dear, your oversized derriere has utterly ruined all of my very hard work."
"I'm mighty sorry, Discord. You shoulda considered the possibility a big gal like me'd put a hole or two through a little pair o' skinny jeans like these, though."
She grinned and gave one of her big ass cheeks a firm pat.
"Quite. Well, no doubt you would have been the centre of attention if my little plan had come to fruition. But you still can be. It's what you deserve, after all."
A black fog unnoticed by Applejack swirled into life in the hidden palm of his hand, crawled down the back of his leg and across the floor, and seeped into her.
"Whaddya mean?" Applejack asked, turning to pick up her glass of juice on the table. Discord took the opportunity to pump a great gout of the fog into her.
"Oh, just that I'm sure that if all goes to plan, you'll still catch everyone's eye."
He nearly spat out the words. Applejack worried the juice she'd served him had gone bad. She smiled.
"Well alrighty, then. I'm real sorry. Hopefully next time we'll sort somethin' out."
Discord managed a rather dark smile, and turned to leave.
"No doubt, Applejack - no doubt."
Before she could escort him to the front door, he had marched out. Applejack idly sipped her juice, watching him go.
"Sure is a strange fella, that one."

"So what happened with Discord?"
Big Mac came in hauling a big basket of apples, setting them down on the table before running himself a glass of water and gulping it down. Applejack was finishing up her dish washing, drying her hands on a towel.
"Oh, uh, didn't go too well. I may have been a mite too big for the jeans. They were real small, though... for me, anyway."
Mac chuckled.
"Not too surprising, not much that ain't too small for that butt of yours."
Applejack rolled her eyes and talked over her shoulder.
"Just 'cus that's true don't mean you gotta say it! Hmph. I—"
Applejack frowned. The seat of her jeans felt tighter, and a pleasant warmth spread through her lower body. She looked over her shoulder - there definitely seemed to be more booty than there had been since the last time she checked. But it was so easy for her to gain weight there, she just put it down to her eating habits as of late. Her hips hadn't measured less than forty inches around for a very long time, and that could increase quite readily given the chance.
"Whatever, I'm nearly late, I gotta have the market stall set up by eleven. I'll sea ya later, Mac."
He rose a hand casually, beginning to inspect the apples he'd brought in for bruises and bugs. Applejack gathered up the last of the crates and trays and loaded them into the family pickup truck. She climbed into the driver's seat and slammed the door, feeling it push against the side of her hip as it closed. That certainly didn't happen yesterday. Weird. Oh well. That made her reflect, as it occasionally did, on the comparative smallness of her breasts.
"Wouldn't be so bad if I had a bigger chest, seems to be what a lotta fellas are into these days. Ain't so sure my big ol' behind is too appealin' to fellas my age. Nobody's perfect, I guess."
Simultaneously, the buttons on her shirt were drawn taught and a quiet ripping sound emanated from around her hips. her breasts quickly gained a cup size or two, putting pressure on her shirt, and her ass had grown a little more once again, putting the seams along the outside of her legs under a lot of strain. She stopped the car.
"What in the world...?"
She studied herself for a good thirty seconds. She didn't believe it, but a quick feel of her newly-enlarged breasts confirmed that they were indeed genuinely larger. The fact her bottom had grown at the same time really made her think. She was beginning to catch on.
"My fingernails."
Her nails were very short, a thin slither of white so that muck couldn't accumulate beneath them after long hours of hard, dirty work. She held her hands up, palms face-down, and studied her fingertips. To her amazement, and as she almost allowed herself to suspect, the white nail on each fingertip began to protrude visibly, gaining perhaps half a centimetre.
Discord. The jeans. The strange smoke when they ripped open. The cold fury in his face that tinged with twitches of sadistic amusement.
"Discord. Why, that little... Ugh. No way I can afford to lose my place at the market, but when I next see that varmint there'll be hell to pay."
She drove on, struggling to get accustomed to the new weight hanging from her chest - and the tightness of her jeans.

"Good to see you Applejack! Was worried you wouldn't make it today, that'd be unlike you."
She smiled and waved to the man who'd run the stall to her left for several years now.
"Nothing to worry about, Clear Cut, just some last minute additions to today's wares."
Her belly grumbled loudly. Damn, she hadn't eaten since yesterday.
"Sounds like your stomach's a little upset with you, AJ. I've told you before how important breakfast is!
Applejack gritted her teeth and groaned as her belly expanded, pushing out her shirt. She now had a visible amount of chub below her breasts. Clear raised an eyebrow.
"Hey, your stomach okay, AJ?
She groaned again as it spilled further forward, un-tucking her shirt as it pushed out. She now looked as though she'd recently enjoyed a large meal.
"Uh, yeah, fine. Took some indigestion pills just before I got here, they play havoc with my innards sometimes, heh."
She turned away from him and bent forward, just managing to tuck her shirt back in over her chubby belly. Clear gawked at her recently-enlarged behind, and couldn't stop himself from speaking aloud.
"Damn, look at that butt..."
Applejack rolled her eyes.
"Gosh darn it!"
Her ass cheeks rose like dough, trying to spill out from the waist of her jeans as they grew once more.
"What amazes me," one of Clear's regular customers offered, "is how wide her hips are. They're amazing."
Applejack groaned as her 'amazing' hips began growing wider, tearing small holes in the sides of her jeans. Gods, her lower body was so big now. All she could do was sit down on her stool, cheeks rosy with both embarrassment and the not-unpleasant sensations of growth, to hide her outrageous curves from view. The stool felt so small now.
Out in the square, in the middle of the bustling market, Applejack saw an upturned cart and large crates spread around it, with two girls talking around it. Applejack knew them well.
"Just what I needed. How are we going to lift these? They must weigh a hundred pounds each."
"How about AJ? If she's not too busy, that is. That girl's got some serious muscles."
Applejack's entire body seemed to shudder. Her muscles groaned as they began to grow, thicken, and expand. She went from toned to well-built in a few seconds. The girls looked in her direction.
"Oh, yeah, she's not too busy. And you're right, jeez, her muscles are pretty huge."
Groaan.
"Yeah. Huh. I don't remember her muscles being that big, though.
Groaaan.
Applejack moaned as her thick, heavy, dense muscles began to tear her clothes apart, seam by seam. Her biceps blossomed into thick, meaty lumps of brawn, her legs exploded outwards, thick and wide and strong. Fuck, she felt like she could bend a steel bar.
The stool couldn't take any more, and broke up beneath her. Half the market turned to hear what had made the unpleasant crunching sound, and saw a musclebound, half-naked girl sat on the floor. Applejack decided it was time to leave before things got really out of hand. She started to tidy up her things, keeping a low profile behind the stall.
Behind her, a couple of young guys had a great view of her huge body.
"Shit, man, look at the ass on her!"
Applejack grunted as her thick ass cheeks tore her jeans apart.
"Hey, is her body changing?
Applejack paused, frowning, then uttered a low moan as her entire body began to grow upwards.
"It is! What the fuck! She's growing, all of her!
Applejack whimpered in pleasure and embarrassment as she sprouted up like a weed, passing eight feet before the growth slowed to a stop.
"Gotta get outta here..."
The two guys stood there, mouths agape.
"This can't be a coincidence, buddy."
"What?"
"Watch. Her ass."
Applejack's butt swelled outwards for the umpteenth time that day, now it looked enormous even on her amazonian, muscular frame. They both shouted "woah!" in unison, making Applejack turn their way, a scowl on her face.
"Will you two get the hell outta here?"
They blinked.
"Sorry, miss. We can't help appreciating a nice ass when we see one, and yours sure is."
Groaaan. Her ass cheeks wobbled as their size increased, they now stuck out a good two and a half feet behind her, sagging slightly from their own weight. They jiggled with the tiniest movement. She instinctively placed her hands against her booty as it expanded outwards, and they sunk easily into the impossibly soft, pliant flesh.
"Dammit, shut your mouths!"
At her huge size, she had no trouble chucking everything quickly into the bed of her pickup in record time. What wasn't so easy was folding her huge body into the cabin. Her giant ass covered the seat and half of the seat next to her, her back was bent forward and her head was almost looking straight down. She couldn't close the door, her ass and hips were simply too thick and wide.
"Thank Celestia for automatic transmission," she muttered to herself as she managed to slide the stick into Drive, pushing against the doughy flesh of her huge thigh. She thought she was in the clear, but had no idea the two guys had been muttering to one another, and had decided they weren't going to let her off that easily - they wanted the show to go on.
As she began to pull away, her whole body tingled. Unknown to her, the guys were chanting something over and over behind her.
She began to grow, rapidly, in all directions. Her feet tore through the foot well, her thighs snapped the gear stick off, her breasts billowed forward, resting on top of the dashboard, her head tore a hole through the roof.
The guys watched the pickup lose speed and stop, a growing figure inside taking up more and more space. They chanted faster, making Applejack's body grow faster. A pause, a rumble, a screeching, ripping sound as Applejack's hips exploded outwards, tearing the cab in half. Her feet smashed their way through the insides of the car, spearing out of the front radiator. Her shoulders burst through the roof. The car couldn't bear several thousands pounds of weight and simply crumpled in half as Applejack tore it open like a tin can. She was still gripping the steering wheel which shrunk smaller and smaller until she was only holding it with her thumbs and forefingers.
The remains of the car disappeared between and beneath her mountainous ass cheeks as she ascended, growing past twenty feet whilst sat down. She guessed (correctly) that the larger she was the more people could see her, so invariably the more comments would be made about her body. All she could do was extend herself to her full incredible height, completely nude with her awe-inspiring musculature and goddess-dwarfing curves for all to see, and make a beeline for home. The two guys finally stopped willing Applejack larger, taken aback by the bodacious giantess filling up their field of vision. At her size she covered ground very quickly, and escaped from their machinations in short order. Her foot steps shook the ground, rattling windows and bouncing people around as she stomped by. Naturally, the odd comment passed their lips as they looked up, awe-struck, and she'd grow a few inches higher, or her ass would pile on even more thickness as the locals watched the hypnotising, jiggly sway of those two enormous globes make their way past.
Things got quieter as she stomped away off into the countryside, only the odd farmhand or someone taking their dog for a walk seeing her enormous body bounding past. She'd only gained a few more feet on her journey home, pushing her just over fifty feet, and her giant ass was only slightly more giant. She'd jogged a good fifteen miles in less than half an hour, and sat herself down beside the barn, drops of sweat the size of melons rolling from her brow and splashing on the dusty earth.
Big Mac was stood in the doorway of the house, shielding his eyes from the sun and looking up at her immense bulk. He sighed. He thought she'd given up on her wild escapades with those crazy friends of hers. She could just about deal with Applejack being small enough to fit in the palm of his hand after that incident with the poison joke, but this? Had she been playing with those elements of harmony or whatever they were called? Sure wasn't going to be much harmony with her at this size.
She was kneeling, wiping the sweat from her brow, the immense bubble of her globular ass extending out a long way behind her and competing in size with the house she'd parked it next to. She saw Big Mac eyeing it.
"Mac, don't you dare."
"Just when I thought your butt couldn't get any bigger."
The ground shook.
