The sky was sunny, a thing that often happened in this world. Frolicking merrily through grassy meadows were huge ponies, tall, thick and meaty for the most part… they were literally african elephant sized monster horses, if not even bigger.
Upon a tall hill a most strange, small creature was laying next to a massive, light blue horse with a rainbow mane, and feathery wings upon her back. That creature… the smaller one was a human, dressed in a navy tracksuit, a light blue hooded jumper, and black sneakers.
For what little skin was exposed it appeared he had a very pale, white pinkish color to it. His hair was short, like he had just come out of bootcamp.
He looked lovingly up at the big blue horse, who was looking down at him with a questioning look. This exchange happened for quite sometime, until he found the courage to speak.
“Rainbow… I” he began, before going silent again.
“You want to tap my ass jack? I’m sorry, but the answer is no.” she stated firmly.
His head lowered, looking down between his legs. “I guess… I can understand. You’re a big pony after all, and I’m just a little human.”
Rainbow’s eyes widen in alarm. “No… no. Your size is not the issue man. It’s just that if Rarity finds out, she will kill me.”
“Rarity!” he shouted in anger. “She has the hots for me? Fuck!”
“Hey! What’s wrong with Rarity?!” she bellowed, staring down at him with narrowed angry eyes.
“I think she’s too girly and a drama queen. I don’t want that kinda girl. I much prefer a tomboy like yourself.”
Rainbow Dash cheeks went a slight shade of pink, a hoof rubbing the back of her neck.
He stood up, a look of determination on his face. “I’m going to tell her why we can’t be together right now.”
With that he marched toward Ponyville, making his way to the tall white tower known as the Carousel Boutique. Once there, he knocked upon the massive pink, diamond encrusted door of the building.
There came a loud sound of clopping hooves for a brief moment, before the door opened to reveal a massive white unicorn, who was a great deal larger than Rainbow, for she was considered petite. Jack, hated to admit it, but Rarity was a very pretty pony. She smelled of perfume, kept in good shape, and was delightfully plump in all the right places.
Not only that… but she seemed literally to have grown much larger than a normal pony, yet still maintaining her feminine beauty. Her body was a tower of meat and mass, she was literally twice the size of an average pony now, perhaps even bigger. Her femininity seemed to be even stronger than before.
“Jack! Hello there! Would you like to come in? I’ll cook you a big bloody steak if you like?” she said in a friendly tone.
‘A steak… nopony has ever offered me that. Maybe, I should give her another... No! Stay focused!” came his thoughts.
“Wow… Rarity… you’ve gotten big.” he said in a low, fearful tone.
Rarity blushed, smiling broadly. “Why thank you Jack. But personally, I think I need to be a little bigger.”
Rarity lit up her horn with magic, turning around in quick session to present her enormous backside to him. Her hooves elongated, inching higher into the air. She grew bigger and bigger, fatter and fatter, heavier and heavier.
Jack stared in a mix of fear and arousal as Rarity assumed greater and greater size.
Her already massive rear-end inflated like a balloon before him, rapidly growing in thickness and height. Her backside was unnaturally smooth, round, and just a plain perfect rump even as it grew even larger by the second. The poor little human could not help but get a boner, her beautiful femininity was simply overpowering. His breath was taken away, all he could do was stare, wide eyed at her growing rump, while his cock was as hard as a diamond in his pants.
The snowy white unicorn’s cheeks jiggled like crazy as more and more flesh was pumped into them. Her growing, succulent rump was simply memorizing to stare at. The human had to resist the powerful urge to fondle it.
Further and further she grew, before finally coming to a stop when she grown three times the size of an african elephant.
Her massive, white rump stood tall and proud before him, casting a vast shadow over the little human. A butt she can make even bigger by a whim.
Rarity stared back at him with a wicked grin, pressing her hoof down upon her right cheek, the soft fat conceding deeply from her applied pressure. Once she pulled her hoof back, her rump returned to its perfectly round bubble butt shape.
“Is there anything I can do for you, Darling?” she said sexfully.
"Goddammit she’s sexy! But she’s annoying as fuck." came his thoughts
“I… uhhh… well Rarity.” he mumbled.
“What is it sweety?” she asked softly, bringing her large head down to level with his body.
“I’m sorry Rarity, but you’re too girly and a drama queen. I don’t want to go out with you.” he said nervously, giving her an awkward smile.
“Jack, give me a chance. You might like me.” she implored, staring at him with pleading doggy eyes.
“I’m sorry Rarity, but I like girls like Rainbow Dash, or Applejack.”
Rarity’s left eye twitched. “You like them filthy mules over me?!” she shouted in shock.
“Okay, I’m going now.” he said, backing away in fear.
“Good! I never want to see you again! Dirty ape!” she roared, slamming the door closed.
He stood there for a brief moment, before hearing a loud wail of grief coming from behind the door.
He sighed. “I had to do it.” he said in a low, somber tone.
With that he turned around to see Rainbow with a very angry look on her face.
“Uhhh, Rainbow. I-I…. I.”
“Oh, don’t worry Jack. I’m not mad at you.” she said softly, giving him a warm smile.
“Why are you here?”
“To make sure you didn't get killed by Rarity.”
“Oh, thanks Rainbow. So, you wanna go for a drink?”
“Not quite yet Jack. You’ve just rejected Rarity. Give me a week, then you can stick your small monkey dick inside me.”
“So, no romantic dinner or anything?”
“Nah.” she said, waving her hoof nonchalantly. “Just give me a nice belly rub and you’re good to go.”
