The Great and Powerful Trixie had heard rumors that this place had some peculiar magical items. Trixe walking up to the rickety old door of the shop. Slowly opening it with her stupendous magic. The old creaky floorboards struggled to hold the magnificent Trixie's weight even though she doesn't weigh that much. Alas, Trixie was unimpressed as they looked over the various oddities within the shop. For there was a frown upon her face. That was until she saw something behind the clerk’s counter that caught her eye. She recently read up about that particular object. She immediately approached him to acquire information about the object. Trixie was able to see the endless potential within the artifact. It called to her as she walked towards the counter.

“Trixie believes that might be a powerful magical item. How much?” Trixie said with her trademark trill. Her voice easily filled the small room which brought the earth pony's eyes onto her gorgeous form. Trixie then put her two front hooves on the table with two clops. The magnificent eyes of Trixie looked between the pony and her new object of desire.

The earth pony clerk sighed. The earth pony clearly is not able to see the potential in the artifact. Earth ponies were never able to see much in terms of powerful objects. Trixie would have to show this pony how he was wrong for posting such a cheap price. 1 bit was an absolute insult to such a magical object.“A cheap price. I just want to get rid of it. Everybody who buys it ends up returning it. It doesn't seem to work. Alicorn Amulet, my ass.”

"Have the customers who bought the amulet all been stallions?” Trixie asks with a mischievous smirk on her face. The eyes of Trixie sparkling with fire as she knows full well about the truth of it. Trixie winks at the pony while licking her lips hungrily. Her horn sparks to life as she grabs a pouch from her satchel. The light blue magic of Trixie grabbing it and putting it on the table. Showing off the money she had gained from her glorious shows which impressed all the ponies she had met. Deciding to brag a bit since she knew She wouldn't have to pay for it.

"I don't see how that has to do with anything. But yes, everyone who has bought this happened to be a stallion, like myself.” the clerk then picked up the object and placed it down in front of Trixie. Trixie let out a slight chuckle while shaking her head. Tsking while shaking her hoof back and forth. Knowing that this pony would not understand such a thing. “Tell you what, if you're so interested I can give it to you for free.” Trixie rolls her eyes in annoyance as she sighs. Letting out a whinny of annoyance as well when she rolls her eyes. Eventually going back to her trademark smile.

Trixie smiled at the stallion before promptly picking up the amulet and wrapping it around her neck. Her blue magic easily grasped the object as it sparked with power. Sensing its new unicorn owner and seeming to glow with glee. Trixie felt her power immediately begin to amplify in strength. She felt a warm tingling feeling flowing through her whole body. Red and black lighting crackled through the air as the room shook with the sudden increase in power. She began to inch upwards into the air, she felt her clothes begin to tighten around her expanding frame. She looked back at her rump, smiled in delight as it rapidly became fatter and fatter. The lighting striking the area around her cutie mark the most and amplifying her cutie mark's magic. Only making sure Trixie would be the greatest magician forever.

Her clothes soon began to rip and tear at the seams, Her hat forcing itself into the air due to the size of her horn. The spiraling horn of trixie sparkling with red energy as lighting sparks off of it due to the alicorn amulet. Trixie's eyes were glowing red now with the amount of power growing behind them as Trixie's brain gained more and more magical knowledge. before ultimately shattering apart into tiny ribbons like torn up present wrapping paper. The cape flying around and sparkling in the light coming through the window. An echoing boom coming from the growth of trixie. The hat of Trixie flying into the air and landing onto the ground across the room. Unlike her clothes, the amulet around Trixie's neck increased in size; keeping base with her rapidly expanding form. The eyes on the amulet sparkled and hummed with red energy as trixie stood there. Trixie's hat then flew back onto her head and latched itself onto her. Glowing with white light before starting to grow to match her proportions, Trixie's hat seemed to expand in size, as it remained on her head and maintained its portions relative to the size of her head.

Her ballooning cheeks caused other magical merchandise to fall over onto a floor with a long bang; shattering into pieces. Most of it was Fine Ponecelain, but Trixie didn’t care. She could sense the other magical items' powers were mundane in strength. Trixie ignites her horn with a glowing red and blue mix of power. Grabbing all of the magical items and sucking the magic out of them like she was Tirek. Absorbing it into her body and making her growth go even faster while Trixie does this.

Trixie giggled at her newfound size. Smirking down at the stallion with Trixie's white teeth which are at least the size of small sticks. Licking Trixie's lips with her red tongue as pleasure sparked along her body along with her growth. Experimentally, she began bouncing her fattening cheeks up and down; she smiled in delight hearing them smack together with a loud meaty clapping sound of flesh, slapping against flesh. It kind of reminded her of the sound of inflatable rafts being thrown around. It brought her back to that moment where she was forced to use rafts on her home so she could cross a river without incident.

Trixie admired her backside some more by placing her front right hoof upon her cutie mark and watched in delight as it sank to the abyss of her cheek like squishy soft light blue play-doh; creating a deep depression. The sparks going around her cutie mark hitting her hoof and causing tingles to go along it. Feeling almost like her hoof had fallen asleep before it faded. The alicorn amulet continued to grow the body of Trixie along with her magic power. She held it there for a moment, before slowly pulling back and watching in joy as it returned to a perfectly smooth shape. It was like a water bed in terms of how it acted at this point. Adjusting to any changes easily before returning to its normal shape.

The mare then approached the clerk with a seductive look in her eyes, her hips swayed from side to side as she grew larger by the second. The echo of her cheeks clapping could be heard as she approached. Her hooves as wide as dinner plates hit the wooden floor with a loud thud each time took a step towards him; Each impact of her heavy hooves upon the floor caused them to crack upon contact. Dust and debris fell from the ceiling, and merchandise fell off shelves from the sheer force of her hooves.

Once she reached him she turned around and presented her massive backside to him. Her tail slapped him in the face and showed off her bits to the stallion. Almost knocking the stallion over with the force of her tail as several things on the counter clatter to the floor from Trixie's tail. The clerk gulped as he stood underneath the growing shadow of her rump. Though his cock betrayed him as it started to grow hard from the musk of Trixie flowing off of her marebits. The stallion could only look on awe as he watched that ass inch upwards into the air like an inflating hot air balloon.

The stallion wanted to embrace her ass, but stood firm and stopped himself. The stallion opened his mouth to voice his protest, but before he had a chance she subsequently dropped her ass down on the counter with a loud bang; crushing everything upon it into a fine dust. causing the stallion to cough and sputter while moving his front right hoof back and forth. Bending down while coughing before then shaking his head. Looking back up at Trixie only for nothing but a croak to come out of his mouth.

“Mmmmm!” she replied with a lustful moan. Her eyes go lidded with pleasure while she shakes her butt back and forth. Sparks going up and down her spine as her horn continues to crackle with power. The growth of trixie's only gets faster and faster with each moment while she claps her cheeks. Teasing the stallion behind her while doing so. Letting the stallion see her cheeks jiggle around like the water. “Allow me to repay you in some other way,” she said in a hot breathy voice; her rump rapidly air ballooning fatter and fatter towards him, quickly closing the distance between him and her. Trixie smacks her fat butt with a hoof which makes it shake around like a tsunami and shake the whole store like a 5.0 earthquake is going on.

The stallion hesitated for a moment whether to embrace her ass or run. The stallion's heart pumps in his chest as he glances towards the door. Knowing full well this crazy mare will eventually grow big enough to block him. The floor creaking and breaking apart under the balloon mare accentuating the dire situation. His legs were shaking in place, and he was sweating all over. For his erection was raging despite that terrifying encounter with this insane mare. His pre drips onto the ground with each throb of its length while he stands there unable to speak. His mouth felt like it was full of cotton as he stood there.

The massive mare began to become impatient, a frown forming upon her face. “Embrace the power of my butt, or embrace your own destruction!” she said in a stern tone; her tail wagging in annoyance, like that of a grumpy cat. The horn of Trixie sparkling and spewing red lighting which created holes in the wall. Massive black holes being burned into them from where the lighting hit it. Trixie growled like an angry dog while she stood there towering over the stallion.

When she said that, his fear got the better of him and he attempted to escape by lunging towards the door of the shop. The stallion desperately attempted to flee as best he could. Wanting to get as far away from the crazy mare as possible. Though this would not come to be. Trixie with a mere flex of her magic lifted him in the air and flung back over to the counter. The horn of trixie glowing like a miniature red sun and grabbing the pony with ease. Flinging him like a rag doll back towards the counter. “Foallish puny mortal! Don't try to escape again! I will leave you off with a warning this time. I will just punish you even more next time!” Trixie's massive face became red hot with anger; her growth accelerating, which caused the stallion to whimper in fear.

In her anger Trixie had now become so heavy the wooden floorboards began to creak and groan from under the strain of her weight. The floor was littered with shrapnel, which were the remains of various magical trinkets. Sparks flying off of them and swirling into a show of stars. going into the body of trixie and combing with her new found power. Making her even more powerful as she growled in annoyance at the pony in front of her. These trinkets however were slowly being crushed as her asscheeks rolled over them like steam rollers. The cutie mark of trixie glowing like a miniature sun and casting an ethereal light blue glow on the room.

"Hehehaha! There is no escape! Puny pipsqueak! Our power only grows stronger the bigger we become! You shall be the first of many dominated by our glorious and mighty fat rump! Our backside will dominate this universe and beyond! You will be buried under our Great and Powerful Ass!” boomed the growing giantess unicorn. Her horn started to dig into the ceiling at this point. Gouging a massive hole in the ceiling as pieces of the ceiling fell to the floor with loud booms. The floorboards then collapsed underneath her; the weight of her hooves digging into the dirt below. Creating indentations in the ground while the unicorn showed off her power to everyone around now. ponies started to gather as they heard the noises coming from the shop.

If he had to guess, the clerk figured this mare might be about the size of a ‘Hipposgigmonus’ he saw in a few history museums. Which is speculated to be related to ponies… only to about twice the size of an elephant. Making images race through his mind while he stood there. This race has mysteriously vanished out of thin air, however nobody could really tell why it happened since this was prehistory. However, there are rumors that Princess Celestia is the last Hipposgigmonus. Luna is not considered a Hipposgigmonus, her rump isn’t fat enough. Giving Celestia the sole role of continuing the species and making more of them. Though she could never find a stallion who could handle her gigantic rump.

At any rate, her growth never seems to be stopping. Giving the stallion even more and more to worship as he stood there. Completely dumbfounded by the growth of the mare in front of him. His mind racing while the cock of his throbs violently as he watches the mountains grow in front of him. Just as he thought that he heard a lustful whisper in his head “and it will never stop.” The stallion is quite concerned by this sudden voice and looking around. Hoping to make sure no one sees this happening before going back to looking at Trixie. His cock twitched at what that might imply, even if it sounded so scary. The heart of the stallion pounding in his chest like crazy. The eyes of his are unable to stop looking at Trixie's booty while his knees shake. Licking his dry lips hungrily while he looks over the mountainous cheeks of Trixie. One Hair along Trixie's luxurious fur was almost the size of his head at this point.

The mare lit up her horn with magic; accelerating her growth even more. Her eyes glowed a sinister red as the Alicorn Amulet’s power flowed through her. Massive amounts of the red magic flooding into her body like a waterfall. The sheer amount of power flooded into the mare causing her veins to bulge and glow red. Her whole body taking on the same sinister sheen of red from the alicorn amulet. Her fat cheeks clapped loudly like thunder as they bounced and jiggled about wildly, making her meaty cheeks clap together from the resulting migrations of fat pumping into them.

“Behold the power of our great and powerful ass!” boomed the rapidly growing mare. The trill of Trixie shaking the whole town with its force as her lungs have expanded a lot at this point. Her simple breaths blowing around paper and objects in the rapidly shrinking free space around her. Her rapidly expanding flanks quickly bulldozed down the walls of the shop, this was accompanied by her head bursting through the ceiling of the building; smashing it apart. Sending pieces of degree flying into the air and slamming into a few buildings. Leaving massive holes in houses as ponies start to run away as best they can.

The counter and the wall behind somehow still stand. However, the counter began to creak and groan beneath the weight of her ass before collapsing with a loud crash. The stallion closed his eyes and accepted his fate as her ass ballooned towards him. Her asscheeks closed in on him; pushing them against the wall, snaring him in a warm bubbly soft prison. She giggled hearing him squirm as her rapidly fattening cheeks pressed against him. He could feel his large erection going between her fat cheeks, the tip kissing her marehood; while her mattress-like cheeks hugged the lower section of his long cock.

The stallion pushed his hips forward; driving his long stallionhood deep into her soaking wet marehood. A loud slurp filling the air as wet mare juices spew out from his thrusts. Getting all over the stallion and making him all sticky though he doesn't stop his thrusting. He moaned as his cock became snared by the powerful walls of her vagina squeezing all over. Trixie giggled as the stallion frantically pistoned to his hips back and forth, causing his balls to slap against her fat cheeks with a loud meaty slap. Indeed, his member was deeply lodged into her crevice of her vagina, but, little by little he was slowly penetrating her less and less as her vagina became ever larger, resulting in him slowly becoming inadequate for the growing mare.

"Hah! Your pathetic love making tool won't be able to compete with Our Great And Powerful Ass for much longer!” Trixie grilled with her loud booming voice. Shaking the remains of the building while the stallion fucked her. Letting out yelps and moans due to the pleasure going up and down her body. Trixie clearly enjoying herself while she absentmindedly thrusted into the cock of the stallion. Trying to make his cock go deeper into her with each thrust though she continues to grow more. Only making it so the stallion felt more and more inadequate under the shadow she was casting.

Indeed, little by little, he was filling her less and less as her ass kept getting fatter and fatter. Forcing him deeper and deeper into the floor of the destroyed shop. Making a pony sized hole as with a loud boom he goes through it. Spitting dust into the air as his bones creak and groan. The sheer weight of the mare means he can no longer move even if he wants to. Though the stallion did manage to get back up to his hooves just barely before beginning to be pushed back once more by the growing mare butt. The stallion hopelessly tried to hump into her expanding sex to prevent this, but it was becoming inevitable. On the plus side the mattress-like cliffs of her fat asscheeks began to ensnare his member in a warm and soft embrace.

The wall behind her then gave away; collapsing into a heap of rubble. The stallion fell backwards onto his back with Trixie following suit bringing her massive ass down upon him. The stallion cried out in pain as the immense weight of her ass bore down on him. Instinctively his hooves grasped her plush cheeks; seeking deeply into their squishy soft depths. It felt as if bones were breaking under the weight. Yet, somehow… they weren’t. The stallion was covered by a red glow from the mass above him. Keeping him from getting crushed into a pancake by the multiton ass of Trixie. He left his body compressed with greater and greater amounts of pressure, yet somehow he lived. His cock was sandwiched by her heavy bubbly cheeks above; ensnaring them in a warm and soft vice. The stallion was filled with a mix of pain and pleasure like a vial of a potion slowly bubbling and filling up. The cock of the stallion throbbing and bobbing up violently. This indeed the case since Trixie was actively pushing her cheeks together; as if her buttcheeks were the walls of an ancient tomb’s hallway closing in on a foolish adventurer. Her hair was like the spikes popping out of the wall as they got closer to him. Though not hurting him but tickling the stallion.

Trixie giggled at the feeling of his cock slowly sinking away from under the depths of her marehood as she grew bigger. Her hair was easily bigger than his body at this point. Leaving the stallion in a hopeless battle against an unending tide of expanding light blue furry cheeks. The stallion's mind rapidly becomes overwhelmed with the pleasure sparking along it. His neurons in his brain were like they were on a rollercoaster as electricity fired all along them. Inch by inch his member began to slip, until with a loud pop. His member was now simply not long enough to enter her; and was only held by the loving embrace of her heavy fat cheeks hot dogging it. He made a desperate attempt to re-enter her sex, he actually succeeded, however his tip barely managed to enter. However, it was only for a fleeting moment as her rump continued to get fatter and fatter; her marehood becoming further and further out of reach.

“Mmmmmm! Yeeessss! You shall be the first of many buried under my great and powerful ass!” boomed the giantess, her backside cartoonishly bloating bigger on top of the stallion. Her rump made a cartoonish bwooomp which shook the area for miles with the very sound itself. Trixie's butt crunching more and more buildings under its growing weight. Breaking off massive pieces of stone and wood which roll up her butt. As if on a conveyor belt the objects she had crushed slowly went between her cheeks to get fully crunched into dust.

The stallion nonetheless paid homage to her ass by placing his hooves upon her lower backside. His hooves upon contact immediately sank to the plush fat as if it was soft Play-Doh. Her growth rate accelerated upon his hooves touching her ass to the point she had to use magical intervention to help him still touch her ass. His hooves slipped through unseen portals in order to to touch such an ass. Hills of blue ass completely submerged his cock in their embrace as her marehood became so distant it was like a waterfall on the top of a mountain. A river her creamy essence was leaking from her vagina; slowly dripping down the thick canyon gap of her succulent cheeks. When it finally reached the bottom it created a milky white pool. Forming into a murky bubbling Swamp of her juices. Bubbles forming and popping as the air fills with her scent. Steam coming off of the Swamp of white colored juices and turning ponies and creatures all around into sex crazed fiends. Massive orgies forming due to the juices of trixie acting as an aphrodisiac to their primal brains.

With her greatly increased mass, she noticed her pool of magic had increased tenfold. She closed her eyes and experimented with a new spell, her horn glowing with a blinding light. The spell spirals itself out of her mind and forms around the grooves of her horn. Slowly going up her horn and eventually reaching the tip of her horn. A loud hum filling the air and shaking the ground as things bounce up and down. A thick fog began to shroud the surroundings of this humble little village. The ponies within the village had long since fled. Trixie didn’t care, her rump will sit on them all eventually. A glowing light blue silhouette of a pony began to take shape behind her, it rose into the air; morphing into shape, its ass cartoonishly bloating outward to match hers. A sinister hue of red glowed around her neck… alicorn amulet came into existence around this perfect clone of Trixie.

The mist dissipated, ponies in the distance could not see two rising hills of Trixie. Trxie laughed out loud with her booming voice as her spell had worked. Knowing that she had truly surpassed that sparkle now in terms of magical prowess. No way that pathetic princess could have this much power at her hoof tips. The original Trixie looked back at her creation with lustful eyes and elevated the stallion upwards between the midsection of her rump’s cheeks. Her clone didn’t need to move, it simply grew her rump toward her creator, resulting in the stallion being eclipsed between their cheeks. The stallion could only utter muffled moans as he sandwiched their fattening cheeks smoothing him on both sides.

The stallion immediately began to feverishly hump his cock against her squishy soft cheek; causing it to depress slightly from the pressure. Though her ass immediately reformed back to normal as the stallion could never hope to make a permanent or lasting dent on her massive rump. The mountain sized cheeks of trixie casting a shadow over the town around her in the form of two globes. He used his two front hooves to gently stroke her plush cheek, his hooves sinking into the soft fat like butter. The stallion while humping his cock against her cheeks also tenderly applied kisses upon her cheek. In between kisses, he would lick her butt. Running his tongue along her fur and gaining some of the sexy juices of trixie onto his mouth. Causing an explosion of pleasure within his mind as his cock throbs violently from the small taste of her cum he had.

Not to leave the clone of Trixie completely devoid of attention. The stallion turned his eyes to the perfect clone of Trixie. Having hearts in his eyes as he was practically in heaven under all this ass. The stallion could die happy at any time having experienced the perfection that was trixie's growing rump. He leveraged the use of back hind legs to stroke her buttcheek with his hooves, making them sink into the soft cheek like wet sand. The cheeks seemed to have a mind of their own as they sucked his hooves in like a mouth before he pulled them out. Rapidly reforming into its previous form before he rubbed his hooves against her butt again.

The two Trixies moaned; growing in unison; their asses advancing across the village; bulldozing down all in their wake. A particular sleepy stallion found himself with a rude awakening as Trixie's right asscheek came smashing through the wall of his bedroom. He subsequently was buried under her ass; his screams muffled as her rump became his entire world. Trixie smiled as the puny little stallion squirmed as he lay buried under her ass. This stallion was a particularly pathetic individual, for his cock was only six inches long when fully erect. She could detect that this puny stallion was also a virgin. His cock was less than half the size of your average twelve inch long member.

Trixie giggled feeling his puny little cock poking against her behemoth of ass on top of him. She rolled her ass back and forth over him; taking delight in hearing him squirm. To rub salt into the wound Trixie decided to make this stallion even more puny. Her horn glowed with magical light, and she made that cock of his even more puny. Inch by inches his member shrunk until it was little more than half an inch long. She moaned as she felt his tiny puny erection prematurely ejaculating upon her fat cheek smothering it.

Trixie began to laugh hysterically upon hearing him cry against her asscheeks. Her asscheeks began to wobble about as massive migrations of fat pumped into them; her weight drastically increased, shushing the stallion as her ass skyrocketed in growth over him, fueled by his tears. Loud meaty slapping sounds could be heard echoing across the land as her buttcheeks smacked together repeatedly.

Trixie's next course of action was to take the stallion inside her. He sank like quicksand into her cheek, and became submerged into her thick fat. His body then dissolved into a rainbow mist, before vanishing into nothing. Being sucked into her body like it was a blackmore. Turned into nothing but more fat on her body as trixie moans aloud. Kicking her legs back and forth happily while she grinds herself into the ground.

His soul became transported into a pocket plane within her body. There the stallion found himself lying upon her bed within her cart. A shadow loomed over him as a massive full blown elephant sized avatar of herself stood over him. The massive elephant sized Trixie descended; dropping her ass down him with a loud slam. She rolled her cheeks back and forth over him; smiling in delight as she heard him squirm. Her rump grew fatter and fatter over him; burying him into the mattress with greater and greater amounts of bubbly soft ass.

Back in the real world the entire village has now become submerged under the two Trixies. The other stallion sandwiched between their cheeks was panting in exhaustion. Slowly he rocked his hips back and forth, rubbing his cock against Trixie's ass. His rubs of their cheeks were far less thorough, they were pretty much patting at this point. Not really able to reach much of it due to how big Trixie was above him. The buildings of the village creaking and groaning under the weight of the pony above them. Bowing back like a palm tree in the wind before breaking apart under the weight of trixie. Cracks start to appear in the air as the power of trixie grows even more. Her cackling filling the air and shaking the fabric of the world with her power. Eventually the rips in the sky start to spark and fill more of the land. leaving the pony below to be crushed by Trixie in this growing void.

A big wall of text appears above as the simulation ends. The stallion Sighing as he pulls the visor off his head. Revealing a massive metal room filled with neon lights and computers beeping and booping. He can hear the voice of another stallion saying to him “I get to choose which mare this time and who gets to be under her”. The stallion then nods and rolls his eyes at his companion. Putting the visor back onto his face and reloading the simulation once more.
