Author's Notes:

Using her Other Side outfit, of course. Again, please don't let this ruin the episode for you if you dislike this kind of content, just ignore the story and remember it's only fanon from my side of the fandom.

Rarity had just finished a new line of outfits for her boutique. They were skintight sleeveless spandex unitards. She especially liked pairing these with the high heels that she was making recently. She would start selling them tomorrow.

It was winter, so Rarity and her friends couldn't engage in their fetish activities outside, aside from peeing themselves and immediately magically cleaning up. But their magic gems allowed them to make as big a mess inside as they wanted, and Rarity thought, why shouldn't she have a little fun with her new outfit?

She put a black version of her outfit on, with high heels to go with them. She didn't really need them, but they made her look prettier, and she loved the contrast of someone so ladylike doing something so dirty. She walked into the middle of her living room. It was time for the fun to begin!

She touched her magic gem, and then lifted her leg and let out a loud fart. She sighed in relief, and then laid on her back with both legs in the air. She touched her magic gem again to make her twice as gassy as her little warmup seconds ago.

FFFFFFFFRRRRRRRRRRT!

Rarity giggled at the unladylike sound that had come out of her. It was twice as loud and long as her last fart.

She let out a few more wet farts before she ran out of gas. She touched her gem again and positioned herself with her behind in the air.

PPPPPPPPFFFFFFFFFFRRRRRRRRRRRRRRT!

After this incredibly long fart, she slapped her butt, made herself gassy again, lay on her stomach, and released a series of loud, wet farts, taking great pleasure in how unladylike she was being.

The room was full of the stench of her farts, but of course she didn't mind. She loved the smell of her farts. And soon the room would be even stinker, as would her outfit.

She used the fart spell one more time.

BBBBBBBBBRRRRRRRRRT!

This deep-pitched fart was slightly shorter than her previous long fart, but equal in volume.

Once Rarity was done with this, she slapped her butt again and touched her gem for a different spell.

Instantly, her bladder was overflowing to bursting point. Rarity loved this, and got to enjoy it more now that she could always clean herself up with her magic gem.

In her current position, Rarity accidentally leaked a little, much to her surprise. A few seconds later, she let go and started to pee, sighing of relief. She could hear the sound of her pee soaking the crotch of her outfit, she could smell her pee along with the fart smell, and she could see the puddle forming around her. And of course she could feel the warm wetness, and the immense relief that came with peeing when her bladder was full.

After four minutes, she finished peeing. Her puddle was massive and the entire front half of her outfit was soaked. She made a metal note to try wetting her outfit in different positions, but for now she was too excited to try her dirtiest kink.

Rarity touched her gem again, while staying in her facedown position. She let out a wet fart, and felt something plop into her outfit. She giggled, then pushed all the way, noisily releasing a large mass of hyperscat into her outfit. The smell mostly drowned out that of her pee and her farts.

She paused for a few moments, taking in what it felt like to soil this outfit. She felt her mess for a few seconds, then touched her gem again. She grunted and pushed out a few logs of more solid waste into her outfit. She sighed in relief once she was done.

Then, feeling particularly dirty, she touched her gem again, and unleashed a torrent of diarrhea into her outfit. She giggled at the state she was in, and stood up. She could feel much of her mess running down the back of her legs.

She touched her gem to make her puddle disappear, and then sat on the floor, feeling her huge mess squish under her rear. She wiggled her butt against the ground to further saturate her outfit with scat.

Once she'd had her fun, she used her gem's magic to clean herself up. Her outfit looked good as new, and didn't smell. No one could ever tell what she had done in it over the past few minutes.

Next, Rarity tried peeing herself in sitting position. It was much like wetting her shorts, so it wasn't really new, but she loved the sensation of her warm, yellow puddle expanding around her butt. She even refilled her bladder when she knew she was about to run out, so she peed for eight minutes straight. She let out a few wet farts during the last four minutes.

After she finished and dried herself off, along with her puddle, she then tried peeing standing up. She let out a moan of pleasure as the wetness flowed down her legs, soaking the lower half of her outfit. She honestly couldn't tell which wetting position she liked better!

Four minutes later she was very wet. After a couple minutes of feeling how wet she was, playing in her puddle and spanking herself for being so naughty, she was dry, as was her floor.

It was now time to indulge in the other part of her scat fetish. She stripped out of her unitard and, using her gem's power, made a huge pile of shit in the middle of her room. About half of it was hyperscat and the other half was logs.

Once Rarity was sure it was big enough, she put her outfit back on. She didn't clean herself up, so the butt of her outfit was dirty. She scratched her butt, and sat down and wiggled her tush against the ground in order to get her outfit dirtier. She stood up, touched her butt with her fingers, and sniffed. It smelled bad, and she liked it.

But she was about to get much dirtier.

Squealing with excitement (and wetting herself slightly), Rarity dove into the big mess she had made in the room, and played around in it. It wasn't quite the same as with the horses, but it was still incredibly fun. More fun than playing in the mud.

Occasionally she would touch her gem and let out a sloppy wet fart. Most of these, she was sure was a shart.

When she'd almost had her fill of playing in her stinky mess, she lay next to it with her legs up and resting on it. She farted again and soiled her dirty, stinky outfit even further. Then she peed, forming another puddle around her.

Once she was satisfied, she touched her gem, and all traces of what had come out of her nether regions had disappeared from both the room and her outfit.

She was about to make dinner when she couldn't resist an urge to do one last thing. Touching her gem again, she filled her outfit with explosive diarrhea, giggling as she felt some of it run down her legs. And she couldn't resist peeing herself and farting some more.

After cleaning herself up, she continued on with the rest of her day. She couldn't wait to wear this outfit with the other girls at the horses in spring.
