You sat in a corner, away from everypony else at a small square shaped, dark brown table. ‘Everypony’, since the others inhabiting the caffe were in fact strange, pastel alien ponies with cartoonishly large eyes. But to them, you were the alien. You, the human wore strange clothes as well, while they were completely naked. You don't even remember wearing a tuxedo before you were teleported into this magical land.
You held a large, white mug in your right hand. You slowly drank down your bitter, black coffee in peace. In between sips of coffee, you would take a spoonful of porridge into your mouth by using a silver dinner spoon. Your porridge lay within a small, white bowl. Greek yogurt covered your porridge, which was accompanied by blueberries, strawberries, sliced bananas, and nuts.
This sweet caffe/baker or whatever still had healthy options, which was nice. You didn’t fancy having literally cake for breakfast like the others you saw here. Nothing eventful happened for quite some time, you simply ate up your porridge.
Until, a ringing came, followed by a door opening up behind you. A blonde haired, pegasus mare you knew all too well arrived in the building, holding a package. Derpy Hooves, truely a kind soul.
Derpy gave you a friendly wave, you in turn waved back at her. She smiled, before moving back to work. You liked that pony. She was one of the few ponies that acknowledged your existence. Her strange, cross-eyed look was adorable. To you, it felt somewhat mean spirited that her parents literally named her Derpy due to her eye condition.
You watched her trot over to the counter to talk with Pinkie Pie behind it. However, you could not hear them over the other ponies talking in the room. She put the package down on the counter during their conversation.
As they talked, Derpy at one point turned around to briefly look at you, before turning back to look at Pinkie. You heard both mares laugh despite the noise in the room from the others.
Once the package was delivered, Derpy turned to face you. The mare walked toward you, and bumped her flank against your leg as she made her way out of the establishment.
You blushed, and your pants became a little tight in excitement as your cock twitched for a brief moment. You then saw a pinkish blur speed towards you. The blur turned out to be Pinkie Pie. She dropped a white, cardboard box on your table.
“She likes you. Just give her these muffins. Then you shall get the booty.” she said, giving you a wink.
“Thanks Pinkie.”
You threw Pinkie a sack of bits onto the table. Pinkie lowered her hoof and pushed the sack of bits towards you upon the table, gesturing to you to take them back.
You gave her a warm smile, she in turn smiled back at you. You took your bits, and placed them back in your pocket. You then took the box of muffins into your hands, and walked out. Today was the day. You shall win the heart of Derpy Hooves.
Conveniently enough, Derpy was right outside. “Hey Derpy, I brought you this.” you said, gesturing to the box in your hands.
Derpy sniffed the box in your hands. “Oh Anon, you are so romantic. You mean those muffins I just delivered were for me?” she said in a joyful tone, her derpy eyes spinning widely about.
Without a word, you opened the box. Derpy gasped in joy upon sight of a dozen delicious blueberry muffins.
She closed the box, and gave you bedroom eyes. The lustful look she was giving you was somewhat comical with her crossed eyed look. "Let's go back to my place and eat these muffins together." she said in a hot steamy voice.
Side-by-side you and Derpy made your way there. Her home was rather unremarkable. It was a similar design like most of the cottages of the town. Derpy pushed open the door for you. Back home on Earth, most houses were under lock and key. At least where you lived anyway. Here, ponies seemed to have little, to no crime so why would they even need locks on their doors?
Moving on, you walked inside the single story house, with Derpy following closely behind you. Her home was rather modest. There was a kitchen, it had a dark brown, square shaped dining table with two stools serving as chairs in the middle of it. This place had many modern appliances. Such as a refrigerator, a microwave, and an oven. Despite the primitive, mediaeval like aesthetic of the building with it mostly being made of wood.
There appeared to be only about three doors in the room. The door behind you was the entrance. You could only assume one was a bathroom, and the other was a bedroom.
"Nice place Derpy." you simply said.
"Oh, stop." Derpy said, waving her right hoof nonchalantly. The pink blush on her cheeks betrayed her on the other hand.
Derpy made her way over to the table and sat down on the far left of it. Conveniently, the other stool was nearby. You made to sit down next to her.
Derpy picked up a muffin out of the box. The moment the muffin was taken, another muffin materialized out of thin air and took its place.
"Unlimited muffins? Oh Anon, I already feel like I want to marry you."
In one fell swoop, she swallowed down the muffin. The mare uttered a hot breathy moan as she began to inch upward in height by each passing second. You stared wide eyed as the pegasus grew before you.
“These muffins are awesome!” she exclaimed happily.
Derpy stood up off her stool. She turned around to face you and gave you a nice view of her growing rump. You stared in awe as new found mass was pumped into her ass. Her rump became a great deal larger when she finally stopped growing. Derpy was now larger than an average pony, who stood at about 4 feet tall. She was now at least 5 feet tall, with her rump at nearly princess tier levels.
"Hey, let me try." you said, reaching into the box with your right hand.
You took a muffin out of the box. The moment you picked up the muffin, another took its place. With that, you quickly scoffed down the muffin. You moaned at the delicious blueberry taste of the muffin.
You waited patiently for something to happen. Derpy stared back at you in anticipation. However, you felt an odd tingling feeling in your pants. Your pants felt a lot tighter than normal.
"Aww. Nothing happened to you." she said sadly.
“Uh, I think my dick just got bigger.”
“Really? Let me see!” she said excitedly, clapping her hooves together.
You stood up, and then pulled down your pants to reveal your penis. Derpy’s mouth formed an ‘O’ shape at the sight of it. You stood at least ten inches and three inches thick while in a flaccid state.
“I will need more muffins to handle that big cock of yours, big guy.”
With that, Derpy reached into the box and took out another muffin from the infinite muffin box. In quick succession, she swallowed down the muffin. Derpy’s eyes rolled into the back of her head as she uttered a deep throaty moan.
Your cock twitched hard at the sight of Derpy growing even further into the air. The power of the muffin flowed into her. A torrent of white creamy liquid leaked out of her marehood, spilling out upon the wooden floor, forming a thick puddle underneath her.
When she finally stopped growing. She was basically the size of Princess Celestia. A full blown horse. If you didn’t know any better, you swore Derpy’s ass was a little bigger than hers. Your cock between your legs was basically as large as a horse cock, more than capable for her size.
You were going to get big pony booty tonight.
You looked in awe at the now larger Derpy Hooves with her massive backside turned to face you. Her huge fat rump was a truly breathtaking sight. She stared back at you with bedroom eyes, while shaking her fat bubbly cheeks from side to side. As her cheeks wobbled wildly about, there came a wonderful sound of flesh slapping against flesh as her bubbly cheeks smacked against one another.
At the same time, Derpy's long, bushy blonde tail wagged excitedly from side to side. Her huge, feathery wings were extended outward as if she was about to take flight. Her plump, meaty pink marehood glistened before you. Her sex was soaking wet with her juices. A river of her creamy essence leaked down the canyon of her buttcheeks, dripping down onto her leg, before finally landing squarely on the floor, and forming a puddle of her love cream.
Between your legs, your massive horse-like cock stood primed and ready for her big fat ass. You partially held your thick cock with your right hand, its sheer thickness meant you could not fully wrap your hand around it. You stood naked, fully ready to give all the love she needed.
“I just wish I could have your massive ass sit on me without hurting me if you grow really big.” you said in a low voice.
“Actually Anon, all ponies have built in anti crush magic.”
“So you can keep getting bigger and bigger without fear?”
“Yep.” she said, giggling in joy, bringing a hoof over her mouth.
The mare reached into the box and took out another muffin, and swallowed it whole. The mare moaned aloud as she once more began to grow in size. Mid-growth, she then took another muffin into her mouth, and then another, and another.
6 feet became 7 feet, 7 feet became 8 feet, 8 feet became 9 feet, 9 feet became 10 feet, 10 feet became 11 feet...
As Derpy gorged on the muffins her ass began to air-balloon out in growth, quickly filling up the room around her. Her rapidly expanding mass soon came to knock over her chair. You walked backward to avoid being hit by the expanding bulk of her rump. A loud creaking sound filled the room as Derpy’s bloating cheek pushed the table across the room.
There came a loud snap as Derpy’s expanding hooves sank into the wooden floor below her, and began to sink into the earth itself below.
“Uh Derpy, don’t you care that you’re basically destroying your own home?” you asked.
“Eh, magic will fix it later.” she said, waving her hoof nonchalantly, before stuffing yet another muffin into her mouth. “Mmm.”
Derpy grew and grew, seemingly without stop. Before long, Derpy’s head came to bump against the ceiling. At the same time, her fat bubbly cheeks began to push against the walls of her cottage, the fat cheeks of her ass depressing deeply against them. Dust and debris began to fall from the ceiling for a brief moment, before the ceiling and the walls began to expand around her, allowing her to grow even further.
Derpy squealed in delight, making a sound like a dog's chew toy. “It seems I can eat all the muffins I like."
Derpy brought her right hoof back, and placed it upon her plump asscheek. She smiled in delight as her heavy hoof sank into her plush rear, a deep depression was formed upon her buttcheek. Once satisfied, she pulled her hoof back. The depression faded as her cheek quickly returned into a perfectly smooth shape.
“Mmm, you want this big fat ass, don’t you?” she said in a hot breathy voice.
You stared in awe at your now even more massive marefriend. She currently stood at about 20 feet tall. Each cheek of her bubbly, perfectly round rump was like an over inflated beach ball. In terms of size she was quite literally on par with an elephant thickness, crossed with a giraffe in height. Her heavy, thick hooves dug deep into the floor before her. Her estimated weight must be ranging somewhere between 10 to 20 tons, if not even more. Her rump alone must have weighed several tons.
Her massive, bubbly rump jutted out from behind her, and looked a little disproportionate to the rest of her body’s respectively large frame. Her rump was perfectly smooth and round, not a hint of sag in the least, despite the great thicknesses of her ass, it seemed to defy gravity itself with its magnificence.
Derpy hiccuped, this was followed by a massive growth spurt. Derpy cried out in bliss, a huge blob of her creamy marecum came blasting out of her vagina. Her seed flew everywhere, like a shotgun blast, hitting you and the walls of her home. You were now covered from head to toe in creamy marecum. The smell of blueberry muffins bombarded your senses.
You stared wide eyed as Derpy skyrocketed into the air. Within a manner of seconds she doubled in size, now reaching 40 feet tall. Derpy hiccuped again, blasting her upward to 80 feet tall.
Her rump was blimp-like in terms of size at this point. The massive bubbly spheres of her cheeks loomed over you, casting a dark shadow over your small form. She was ten feet taller than the dinosaur known as a Breviparopus. Breviparopus had a much longer neck than a pony, so therefore Derpy’s mass was much greater. You couldn’t even see the entirety of Derpy’s massive, bubbly ass up close without walking back a great deal to see it.
Derpy’s massive butt cheeks pressed against the walls of her home, the squishy soft fat of her butt depressing deeply against the walls. Dust and debris fell from the ceiling, and several bricks became loose. Her home soon expanded away from Derpy, stopping her from destroying it.
“Oh, my. Look how big I am.” she said, blushing at her new size.
You walked forward to embrace her huge rump. However, you only managed to reach her thick, back hind legs, which were like red wood trees in terms of thickness at this point.
Derpy giggled."Here, let me help you."
In one quick motion, Derpy stepped forward, and then proceeded to slam her massive ass hard upon the wooden floor underneath her. The wooden floor cracked like glass underneath her upon impact from under her heavy rump.
Her moist, dripping wet marehood lay before you between her thick hind legs. The shadow of her massive ass loomed over you as it stood tall and mighty into the air.
You walked between Derpy’s thick hind legs. You then found yourself walking upon a seemingly invisible staircase, allowing you access to her upper rump. You now stood above her marehood, her puffy, pink ponut lay before you. Slightly above that lay her tail. Her soft tail came to snake itself around you, wrapping you in a warm embrace.
You placed your hands on both sides of her bubbly, upper cheeks, your hands sank into the plush, soft flesh of her ass. Her soft fur brushed against your skin as you did so. Her cheeks were so wide, that you couldn't even reach either of her cutie marks without going down lower, and leaving the canyon between her cheeks.
You stared at Derpy looking back at you with her signature cross-eyed look. Her eyes alone were like the size of british double decker buses at this point. Her right eye was out of focus, seemingly staring out into space. Her left eye would look at you for a brief moment of time, before her eye looked at a random direction, before returning to look back at you.
You pulled your hand back far, before delivering a hard slap on her buttcheek. Derpy uttered a happy whinny as her rump wobbled like jello upon impact. This was accompanied by a delightful, meaty slapping sound as her asscheek slapped against the other one.
Derpy could not help herself, she reached into the box to grab another muffin to make herself even bigger for you. However, the sheer thickness of her red wood tree-like hoof made that next to impossible. Derpy grunted in frustration at this turn of events. Just when all hope was lost. The box magically enlarged itself, allowing Derpy to fit her hoof inside.
With the box now larger, Derpy reached into the box and ate another muffin. You saw her crane her neck back, while uttering a deep, throaty moan.
You were pushed back slightly as newfound mass flowed into her rump. The sight was simply breathtaking. You thrust your hips forward, slipping your cock between her soft tail. As you did so, the lower half of your cock came to hotdog the thick canyon of her buttcheeks.
Derpy squeezed her asscheeks together, sandwiching your cock between her soft, heavy cheeks. You moaned as her soft cheeks came to smother your cock. As your member thrust back and forth, it rubbed against Derpy’s hot ponut below.
Derpy giggled as she felt you happily hump her growing ass with your cock. While still growing, she took more and more muffins into her mouth.
Derpy’s air ballooning rump pushed against you as it grew in size. The space between her buttcheeks came wider and wider as more and more mass flowed into her rump. As she grew taller, you found yourself slipping lower and lower between her asscheeks, your cock sliding long the canyon of her buttcheeks. Her plump, soaking wet marehood soon came into view as you found yourself standing back down on the floor below.
Derpy's rump alone was at least 100 feet tall in height. A dark shadow loomed over you as her great bubbly mass dominated your vision. You watched in awe as Derpy's ass quickly air ballooned up in growth.
She was jumping up in height by about 10 feet every second. 100 feet became 110 feet, 110 feet became 120 feet, 120 feet became 130 feet, 130 feet became 140 feet, 140 feet became 150 feet. Just then, Derpy hiccuped, blasting upward to 300 feet tall.
Her marehood at this point was like a huge cave entrance. You had nowhere near a big enough cock for her. Derpy pressed her legs together, tightly squeezing you between her thick thighs, trapping you in darkness. You shuddered at the feel of her soft, warm flesh squeezing against your bare skin.
The scent of marehood drove you wild. In the darkness between her legs, you hungrily ate her out. You could hear Derpy utter a loud whinny in response.
With magical aid, you could see Derpy lift the box with her right hoof. The mare leaned her head back and opened her mouth wide. She lifted the box above her mouth, and allowed the muffins to freely fall out of it. Like a continuous stream, droves of muffins fell out of the box, each one falling squarely into Derpy’s mouth. Derpy didn’t even need to chew on the muffins, she just swallowed them whole.
Faster than ever, Derpy began to grow. The power of the muffins flowed through her as she reached greater and greater size. You soon found yourself pulled between her asscheeks, the thick cheeks of her ass came to squeeze your small body between them. You cried out at the feel of your cock being smothered between her soft, warm hilly asscheeks.
The muffins began to grow much bigger, which in turn added even more growth to Derpy. Derpy skyrocketed into the air at great speed with larger muffins flowing into her. Her head soon came to bump against the ceiling, her massive bubbly flanks began to press against the walls, depressing deeply against them.
There came a loud crash as Derpy bulldozed down her room. Her head came shooting through the roof, her flanks burst through the walls of her home, and came speeding toward nearby houses.
Ponies on the street panicked, attempting to flee while screaming in fear. They tried and failed to do so. Derpy’s hyper expanding flanks came rolling over them at great speed, giving them no time to escape. Thankfully, the ponies remained unharmed under her. Their tiny bodies remained intact, and still could breathe even with Derpy’s plush flesh smothering them.
Derpy cried out in pure ecstasy, her tongue lolling out of her mouth as she drooled profusely. She was totally lost to the world in growing bliss. Muffin after muffin fell into her mouth, each one causing her to have a massive growth spurt. Steadily, the muffins grew larger themselves, which helped her grow faster and faster with each new muffin eaten.
The town of Ponyville soon was utterly destroyed as Derpy’s rump ploughed through building after building. It wasn’t long until Derpy had the whole town smothered under her ass. Even then, she kept expanding, her right flank began to advance over the surrounding countryside. Her right flank came speeding toward the outskirts of the Everfree forest, flattening trees as her rump rolled over them.
The inhabitants of the town turned into a rainbow mist and became absorbed into her body, safeguarding them from her butt’s destruction. They looked around in confusion as they found themselves back in Ponyville somehow with Derpy nowhere in sight.
The inhabitants fueled Derpy’s growth even more. Their matter and magical essence fed her growth. A horn materialized atop her head, her alicornation caused yet more growth. The grey alicorn mare moaned a loud, as she trusted her hips back and forth, grinding her massive ass on the earth below her.
Her mighty butt plowed deep into the earth. A deep underground Diamond Dog mining colony filled with gems was soon captured into her ass, they remained unharmed, even as the ceiling collapsed on top of them. They lay unable to move with piles of rocks on top of them. Until Derpy’s growing ass closed in on them, and absorbed them into her body. They were confused at this turn of events as they found themselves back in their mine with the ceiling still intact.
Derpy's flanks rolled across the countryside, flattening everything in their wake, and turning every living thing into a magical mist, which she absorbed into her. Derpy’s right flank soon had the entire Everfreee Forest smothered under her. Her left flank came speeding toward Canterlot mountain.
With a loud slam, her hyper expanding cheek smashed into Canterlot mountain, sending dust and debris high into the air. A flood of rainbow mist poured out of the city of Canterlot into Derpy’s body. Soon, the entire mountain itself became flatten under Derpy’s growing weight and size. Soon, the planet itself was split in half due to the power of Derpy’s growing rump. This was followed shortly with the planet being simply turned into a rainbow mist, and sucked into her. The planet was good as new inside her, nice and safe.
“I just don’t know what went wrong.” she said, before eating more muffins to grow even bigger.
Derpy grew and grew into space itself, the universe was now at her mercy. She licked her lips at the distant stars, wishing to take them into her as well. You were only too happy to encourage her to eat more muffins.
“That’s my Derpy. Keep eating them muffins. You just keep getting more sexy.”
Derpy squealed in delight, making a sound like a dog's chew toy. Derpy ate even more muffins, hoping to fill the universe with her mass and beyond.
