Big Problem
After all the bullshit Twilight had been through over the years she summoned a handsome ape from another dimension to fuck her after she became Equestria’s ruler. You were that human, and were more than happy to oblige. You even got married the day after you fucked her on her night she became ruler of Equestria. Her friends were a little confused as to why she wanted to fuck some random hairless ape, but they supported your love nonetheless.
Your marriage to Twilight seemed perfect, too perfect even. You could literally live happily ever after with her since alicorns by proxy give immortality to their lovers, and even friends. But there was just one problem, she was slowly getting bigger and bigger, and there seemed to be no sign of her stopping. It was enjoyable at first with more padding on her ass, but now it's gotten to the point that it is becoming a bit ridiculous.
In present day you saw the massive form of Twilight standing over you as you lay on a huge purple love heart shaped bed.
Twilight put Celestia to shame. She had literally at this point become about the size of an african elephant, if not even bigger. The round, bubbly beach ball like cheeks of her huge rump cast a dark shadow over your small form.
“Anon, am I still beautiful?” she asked in a worried tone.
“Yes, Twilight you’re still beautiful. You’ve just gotten a little bigger over the years.”
She sighed happily, before descending down upon you with a hard slam from her massive rump, covering your entire body beneath her ass.
Thankfully, her magic safeguarded you from being crushed into bloody jelly, but it hurt a little from the sheer force of her rump, causing you to unleash a muffled grunt into her ass.
Many more years went by… and Twilight was still not done growing. Twilight had become so large she wasn't even able to fit in her own castle anymore, and long since banished herself into the Everfree Forest.
She was literally a brontosaurus on steroids in terms of size at this point, with an ass that seemed like a massive bouncy castle. Pinkie Pie enjoyed herself jumping up and down on her inflated rump.
“Wee!” shouted Pinkie.
You, and her friends stood below her as she sat down in front of you, her huge form casting a dark shadow over you.
“I’m sorry everypony, I just seem to be getting bigger and bigger… without stop.” Twilight said in a low voice, which was quite loud over her sheer size.
“Eh, I’m sure it will stop eventually,” said Rainbow Dash, waving her hoof nonchalantly.
One thousand years later Twilight became so large she covered half of Equestria.
“Oh shit! She really is just going to keep getting bigger and bigger.” said Rainbow Dash.
“This isn’t going to stop.” Twilight said in a low voice, a single tear falling down her cheek.
Twilight felt humiliated. Sure, she became even more powerful than before, and was easily able to defeat the return of Tirek, Chrysalis, and Cozy Glow. But her ass was now a vast mountain in terms of size. Thankfully, no creature could be harmed from under her thanks to her weight protection magic.
Telepathically Twilight spoke into your mind. “Anon, am I still the beautiful pony you fucked on the night I became ruler of Equestria?”
“Twilight, I don’t care how big you get, you will always be my little Twilight.”
“Oh Anon!” she said softly, tears of joy falling down her cheeks.
Suddenly her cutie marks glowed with bright rainbow light... and Twilight had a massive growth spurt. Twilight skyrocket into the air and out into space.
Twilight could be heard moaning aloud all across the land, the growth stimulated every nerve of her body. Soon, the planet cracked below her as her rump rolled across the planet like tidal waves, the growth was so strong it broke the defenses of her weight protection magic.
Twilight gasped in horror. She acted quickly, teleporting all the inhabitants of the world unto her back. You were teleported into her vagina, which she thought during her euphoria was the safest place to be. Sure, it was dark and wet in here, but it was warm and safe.
With a flash of Magic she created a perfect replica of Equestria on her back, however this Equestria was flat in shape. Those who died during the carnage her ass had brought were resurrected, good as new.
Twilight's body expanded out into space filling up the local solar system. Her massive rump smashed into nearby planets, sending them hurtling out into space. Twilight felt horny and began to feverishly masturbate with her planet sized hooves into her huge meaty marehood.
“Yes… bigger… bigger.” she cried.
A planet's ocean’s worth of cum began to leak from her marehood as she grinded her hoof across the thick, plump lips of her sex.
The inhabitants on her back began to massage Twilight. She moaned in appreciation, sending forth small avatars of herself to have sex with those who are willing. A particularly large avatar was sent to you, the avatar for you was about the size of an african elephant.
You embraced this Twilight with your hands in the air in worship. The avatar smiled, before growing even bigger before you. She grew into the air quickly filling up space within the dark confines of her greater form's vagina. Her body began to press against the walls of the marehood. Fortunately the growth slowed down a great deal, this avatar only grew to catch up with the expanding walls of the vagina.
With magical aid, you were allowed to see her greater form’s rump soon bump into the sun. However, rather than burn her, it simply absorbed into her, causing her to have an even greater growth spurt.
Twilight grew.. and grew… and grew. In no time at all she reached another solar system.
“Make love to me, Anon!” she cried out, her powerful voice echoing in her vagina.
“Of course, friendship is magic!”
“Oh yes! Friendship is magic!” she moaned.
With that her greater form exploded outward in size becoming a galaxy in size. The aliens of the galaxy now lived on her back and joined in the avatar orgy of herself upon it.
Twilight looked at nearby galaxies, licking her lips.
“I wonder how many more friends I can make?”
