Firstly, this was an old commission I got from November from https://www.deviantart.com/traupa (original not posted), make sure to check them out!

I've waited so long to post this on my page since as with all commissions I get, I usually want to write a story to go along with it. It took me a while but lost motivation due to life at the time, then forgot about it but remembered recently! Took a little break in between other projects to write this small diddy for it!

I've never seen an episode of MLP in my life but I love their designs.

Following story is done by me:

*****

"So you just want me to stand here?" Nafster asked, standing in front of a camera with a purple gradient background behind him.

"Yes, that's perfect!" Amelia said with a thumbs up.

"Tell me again why I needed to be here so early, and how you set this up in my apartment so fast?" Nafster asked with a risen eyebrow.

"Because you promised you'd help me and I have a lot of stuff to do later!" Amelia answered. "And you know me, I'm a fast worker!"

"Can I at least get dressed? I'd rather not be photographed in my boxers and this shirt."

"No need! Because that's apart of the test for my invention!" Amelia answered. "This camera will change you so you'll fit perfectly with the gradient behind you. It's a two-step invention!" The camera does the transforming part, the background does the choosing part!"

"Wait, did you say it will change me or my clothes?" Nafster rose an eyebrow.

"Both!" Amelia said with a giggle as she snapped a photo.

In an instant, Nafster was hit with a gust of wind that blew his gray hair and ears up. Not just that, but his clothes were entirely different as well. The sleeves of Nafster's shirt were much shorter, rather than reaching his forearms like they used to were now barely passed his shoulders and ended with ruffles. The collar of his shirt was much lower, the crew neck now a V-Neck that reached down to his chest, and the black shirt was now blue. This would be tucked into his transformed boxers. The legs of them merged together and grew down to just above his knees as the blue color turned black with a purple lining around the waist as he was now in a skirt.

"Ah! What the heck!?" Nafster was shocked by the near-instant change, putting his hands on the waist of the skirt trying to move it, though the outfit was more snug than he anticipated. He blushed at the sudden breeze between his legs from the openness of the skirt.

"Isn't that outfit cute?" Amelia asked with a giggle. "But you're not even close to done! That outfit is a keeper, but you're body just doesn't fit it! The color scheme is all wrong! Don't worry, this next pic will fix things up!"

"Wait, let's talk-" Nafster questioned but was cut off by another snap of Amelia's camera.

Nafster blinked a few times, noticing that his muzzle looked different now. His nose was no longer pink, and instead merely slits on the end of his muzzle. The gray on his face was also lighter, more white than gray now as spots started to vanish on it. His ears were longer, while the insides of them were no longer pink, instead simply the same white color that the fur around it was. Nafster's hair was much longer and puffier, as well as a definite dark purple color. It was fairly disorganized, though in the process of forming curls in it. Sticking out from it would be the end of a white horn that started protruding out from Nafster's head.

Below the neck, Nafster's arms were starting to take on a more slender shape. His hands were smaller, fingers longer and thinner having a more feminine appearance overall. Nafster's fur from the elbows up was entirely white rather than gray with spots. The same would happen at Nafster's feet with one key difference; his paws were shrinking and hardening as all the digits of them started merging into one. The claws at the end of them were also gone entirely. From behind him, Nafster's tail would have the greatest change so far. There didn't seem like there was any mass to the tail, rather it appeared more hair-like. Nafster's tail was a light shade of purple, flowing and thin.

"Are you turning me into a girl? I didn't even have my coffee yet!" Nafster exclaimed as he looked down at his transformed hands.

"I could answer you, or I could let the next photo answer for you!" Amelia giggled as she snapped another picture.

Nafster's face was now nearly all transformed, with the gray fur now fully snowball white. His hair became more organized, growing down passed her shoulders. The hair was curved around his horn now, revealing it fully. His eyebrows were longer complete with mascara, eyebrows much thinner and feminine overall. On Nafster's eyes light blue eyeshadow would also find its way being magically applied. The lump in Nafster's throat became much smaller, leaving him with a much higher-pitched voice.

Nafster's shoulders cracked downward, losing their broadness overall. The sides of his body pushed inward, as would his black to give his body more curves to it. The biggest addition to Nafster's body would be two mounds of flesh that ballooned out from his chest as he grew a pair of breasts. Due to the cut of Nafster's top, an amount of cleavage was revealed to the air.

Between his legs, Nafster's knees suddenly locked together and pointed inward. His legs themselves formed their own set of curves as they became much more shapely. Nafster's paws were now fully shifted into pair of hooves instead. His hips were much wider, rear significantly more pronounced. Lastly, Nafster's manhood between his legs was lost as the transformation came to a close.

"And all done! Take a good look at your body! You came out so cute!"

Nafster looked down at his body with a harsh blush, hand to the side in a fist, and the other up to his chin holding his index finger up to it. "I-I guess so...?" Nafster blushed with an awkward smile on his muzzle.

"You make a cute Rarity! I got to run, don't worry! It'll wear off...eventually, I don't remember how long!"

"Wait, what?" Nafster turned to Amelia who was already leaving.

"Bye Nafster! Or Rarity! Whatever you prefer!" she said as she waved Nafster off and left his place.

"W-well...not how I expected this morning to go..." she looked down at her outfit.

"...she had to choose such an uncomfortable outfit for me..."
