Twilight

When Glitter finally regained consciousness, her room was a hot, sticky mess.

"I should probably clean this up, then I really need to speak to Twilight."

With a simple wave of her horn the cleaning only took a few minutes, then she changed into a fresh set of clothes.

"Looks like all my clothes transformed too," she remarked while examining herself in the mirror.

Turning to look at her rear, she noted, "Wow, I never knew my butt was so… plump."

However, a new dilemma struck her as she turned to face the mirror again.

"But what am I supposed to do about this?"

The tight leggings she wore left little to the imagination, outlining her shaft perfectly, with a length reaching all the way down to her knee.

"I can't walk around like this, I'll just have to teleport over to Twili's and hope she's got some free time.

* * *

With a poof, Glitter materialized out of thin air.

"Woah, why's it so dark in here?"

Navigating through Twilight's treehouse, she clumsily knocked things over and stumbled into furniture.

"Twilight?" she whispered, receiving no response.

Making her way upstairs, Glitter was suddenly halted by a sound – moaning, intense and unmistakable. Realizing she was in a place she wasn't supposed to be, she hesitated but curiosity urged her forward.

Approaching Twilight's bedroom door, which was slightly ajar, she couldn't resist the urge to peek inside, and there Twilight was, seemingly affected by the same transformation that Glitter was experiencing.

Twilight lay sprawled out on her bed, with her hand nestled between her legs. She moved her hand in a circular motion and each time she did she let out a loud moan.

Beads of sweat trickled off her body as the act she was performing got more intense. Lewd, sloppy sounds resounded from Twilights nether regions.

Glitter stood frozen in the hallway, her eye still peeking through the small space between the door and the wall.

"Is that really Twilight? She so… hot"

Glitter was mesmerised by what she saw unfolding before her. Then she suddenly started to feel the same sensation again, her pants got tighter and tighter, her shaft was fighting to stay in place, it was on the brink of ripping straight through her leggings again.

She pushed it back down with both hands.

"Oof, that hurts but…. not in a bad way. Crap this isn't good, I need to get out of here right now"

In an attempt to leave as quickly as possible she knocked over a plant in the hallway but quickly caught it before it hit the floor.

"Phew" she said

When she looked back through the door Twilight was gone.

"Can I help you with something Glitter?"

Glitter jolted at the surprise voice behind her

Twilight stood behind Glitter, now fully clothed. She wore short shorts that could barely hold in her butt cheeks, and a crop top that was clearly too small for her huge breasts.

Glitter audibly gulped when she saw Twilight.

"Twi! Just the Pony I was looking for hehe. I could really use your help" said Glitter.

"Mhm, follow me to my study" Twlight floated down the stairs using her magic and Glitter followed behind.

Twilight floated up to one of the higher bookshelves and brought down a huge book.

"So as you can see we've clearly undergone some form of metamorphosis, which form we've taken? I can't be too sure, I've never seen creatures like this before. However I've deduced that this occurred last night when everypony was celebrating the Grand Galloping Gala. It's the only time when everybody could've been affected simultaneously. However you & I and the others all stayed in ponyville to celebrate the gala, so unless us ponyville residents are the only ones affected, then I've deduced that the only common factor was last nights storm."

As twlight paced back & forth brainstorming, Glitter was preoccupied with other matters.

She watched as Twilight's breasts bounced up and down with every step she took, carefully admiring the way her shorts barely covered her butt.

"I want to hold her, I don't know why but I just do. I need to feel her warmth sink into my fingers." She thought to herself

"Hey, are you even liste-" Twilight froze in place, she had finally taken notice of what Glitter was packing in her leggings, and it was on the brink of jumping out to say hello.

"Don't look it's disgusting, I don't know why I have it, that's why I came here. I really need your help Twilight" Explained Glitter.

"It's so big, why didn't you tell me you had one" as if mesmerised by the sight of Glitters imprint, Twilight activated her horn and floated over to Glitter.

"Uhh Twi? Twilight are you okay? Hello?" said Glitter.

"Just… just let me hold it for a minute, okay? I won't do anything weird I promise I just wanna hold it."

Twilight was in a trance, she wasn't even looking at Glitter anymore, her eyes were permanently fixed on Glitters crotch.

"Twi we really shouldn't."

"Oh but we really should" replied Twilight

Using her magic she ripped a small hole in Glitters leggings, crawled right up to Glitter on all fours, wrapped her arms around her and took a huge sniff of her shaft.

This seemed to put Twilight in even more of a daze. She was no longer thinking rationally.

"Cmon Glitter take it out just for a sec, pleeease" she begged.

"Twilight we can't do this, you're not in your right mind. Also you're one of my best friends, we can't" explained Glitter.

Twilight stopped sniffing and stood up, she turned and walked away from Glitter.

"Fine, but when you go I'll be here all alone playing with myself." She said seductively, pulling her shorts up even higher into her butt cheeks so they were barely visible anymore.

This seemed to trigger Glitter, with that small action Twilight performed, Glitters members tore straight through her leggings, revealing itself to the cool air.

Twilights eyes widened, she was visibly stunned.

"Now look what you've done," said Glitter.
