Author's Notes:

I threw this extra chapter in from a combination of the first chapter missing something of which the story is a turn-off to some without it, and someone else saying I should do this.

Rarity ran along the path to her home as fast as she could, not wanting anyone to see her in her current state. Her panties were full of a muddy brown mess, some of which had stained the back of her skirt and leaked down her legs. She also smelled really bad.

So far, Rarity had managed to stay out of sight, but as she neared the block her house was on, she froze. Two people were walking in her direction, fast. Her heart was pounding. They were about to discover that she had soiled herself.

Rarity looked for a place to hide, but couldn't find anything suitable. However, there did happen to be a pool of mud to the side, at an unfinished driveway next to a house whose construction had recently finished.

Rarity hated getting dirty, but this was preferable to total humiliation. With only a few seconds' hesitation, Rarity jumped into the mud, and played around in it so she was covered from head to foot, hiding any traces of her accident. Except for the smell, but she hoped they'd think it was something else.

Rarity got into a sitting position, squealing a bit as she felt the mess inside her panties squish under her rear. But... she didn't exactly dislike it. Something about it seemed so... arousing. Did she actually like this sensation? And why didn't she seem to hate the mud right now? She had always thought of dirt as repulsive, but now that she had to get dirty, she couldn't help but feel she secretly liked it...

The two people, a boy and a girl, walked by, and looked over at Rarity. Rarity blushed a little, wondering if it might be too suspicious that a girl like her would willingly play in the mud. They brushed it off and kept walking. They had seen Pinkie Pie and Applejack play in the mud; they knew Rarity liked Applejack and figured that she had rubbed off on her.

Once they were gone, Rarity sat in the mud for about ten more minutes, until she felt the familiar sensation inside her bowels, and ran home as fast as she could.

She got into the bathroom, and paused. Her heart was pounding again. Now that no one was here to witness her humiliation... she could allow herself to enjoy being messy and unladylike.

Rarity lifted her leg and let out a loud fart, sighing of relief. Over the next ten minutes she farted several more times, each fart loud, wet, and smelly, some of them long.

PPFFFFFT! FFFFRRRRRRT! BRRRRAAAP! PPPPPRRRRRT! PPPBBBBTH!

Rarity giggled with each fart. She didn't know why she enjoyed this so much. This was a side of her she had never known, and would never dare show to her friends. Except maybe Applejack.

After a while, Rarity felt that she needed to take a dump, just as badly as the last time. She walked over to the toilet and was about to pull her panties down, when she stopped. She was already dirty and smelly, and she couldn't help but wonder how much she had secretly enjoyed her accident.

She stepped into the bathtub, and with a loud, wet fart, she released the contents of her bowels into her underwear, sighing in satisfaction as she enjoyed it thoroughly, unlike last time in which it was a potentially humiliating accident.

Her bladder was full by now too, so she peed in her panties, finding this just as fun as messing herself. Afterwards, she sat down, enjoying the squishy sensation of her shit against her bottom as she squirmed around a bit.

After sitting in her filthy, smelly state for about half an hour, Rarity decided she was done for now. She took a very long shower, and then removed her soaking wet outfit and took a long bubblebath, and was surprised to find she was actually disappointed that she didn't fart in the tub. It seemed her bowels were back to normal. Afterwards, she changed into a clean dress that she thought was fashionable, wanting to return to her ladylike self now that this was done (though she knew she'd still enjoy doing this whenever she got the chance).

She threw her outfit, which was still a little dirty, into the washing machine with the most powerful detergent she had. Her skirt cleaned up surprisingly well, although her panties were still heavily stained. Instead of throwing them out, she decided to keep them for her "activities" in the future.
