Sunset's M-ASS-IVE discovery

*SIX MONTHS LATER*

"Morning, Sunset. How are you doing today?" asked Applejack as she entered her family's barn.

"So far, so good. I would be better if I could still walk." said Sunset looking at her enormous ass.

Sunset's backside had grown to a point where the only place she could easily fit, was the Apple family barn, due to some of the other students accidentally saying the trigger word. On the upside, her new size allowed Rarity to create a line of clothes for people with enlarged features.

”Do you need anything before I leave?”

"I'm good for now,but thanks anyways."

"Alright then. Oh. Before I forget, Rarity just called saying that she'll drop by with some new undergarments for you." said Applejack as she made her way to the door.

"That's good to hear. I hope the others get to drop soon." replied Sunset.

"I'll let the others know you said that. See ya after school, Sunset." said Applejack.

Sunset leaned back on her rump and softly smiled to herself.

"I'm so glad that I have great friends to rely on. Hopefully, we continue to grow closer in the future. said Sunset accidentally saying the trigger word.

Sunset only realized her mistake when she felt the familiar process of her ass getting bigger. By the time it was done, Sunset's rear end was gently pressing against the barn's walls.

"For the love of Celestia. This is going to be a long day.". said Sunset pinching the bridge of her nose.
