Rarity walked into her backyard again after a fun day with her friends. She was once again wearing her light blue tank top and skintight purple shorts, which were now spotlessly clean - but that would change!

Around her neck was a thin chain necklace with a crystal on it. Rarity had found it exploring a cave. It had glowed bright when she got near it, as if it could sense something about her. She knew the crystal must contain Equestrian magic, and took it. As soon as she touched it, she knew what kind of power it had, and why it reacted to her.

Rarity held the crystal and used its magic on herself.

Immediately, she could feel an urgent need to take a dump. She quickly got her shorts and light blue panties down and released the contents of her bowels in the center of the yard.

She had used the crystal to make herself poop for an unrealistically long amount of time, and when she was done, there was a pile of shit in her yard bigger than the section of mud. Satisfied, Rarity pulled up her shorts, and rubbed her butt a little, feeling her underwear get a little dirty.

She held the crystal again and cast another spell.

Almost immediately, Rarity released a series of loud, wet farts. She giggled with each one, slapping her butt occasionally. These farts were louder, wetter, and smellier than when she wasn't using magic to satisfy her fetishes.

After about a minute, her farts had turned the back of her shorts brown. Rarity held the crystal again and cast another spell while still farting.

She could feel her bladder become more full than ever before. She had never been this desperate. She let out another boisterous fart, and suddenly lost control.

She was surprised when her shorts started to grow warm and wet, but she liked it. She peed harder, letting it flow down her legs in torrents, farting every once and a while, and letting out a moan of pleasure.

Rarity peed herself for about three and a half minutes, and felt relieved but a little disappointed when it was over. No matter - she could use the crystal's magic to pee again if she wanted. Maybe for five minutes this time.

She rubbed the crystal again. Make me fart for a bit and then soil myself.

Rarity let out louder, wetter farts than before, and after about another minute, her next fart released a brown mess into her already-dirty shorts. She quickly touched the crystal, and a few seconds later, she messed herself again for about ten seconds. Her shorts were now full of a wet, smelly mess, and she loved it.

After rubbing her butt for a few seconds, Rarity dove into her pile of shit, playing around in it and loving it. Soon she was covered in her scat from head to toe, and sat still for a while, taking in every second. This was even dirtier than mud, and she never thought she'd get the chance to do this.

BBBBBBBLLLLLLLLRRRRRRRRRT!

Rarity made another noisy mess in her shorts, and giggled. She peed again, and let out several more farts, some of which were more than just a fart.

Once she had enough - and had taken the time to pee for five minutes - Rarity stood up and walked back onto the grass. She was dirtier and smellier than she had ever been in her life, and she felt so aroused by it. She was so excited she accidentally peed again, much to her pleasant surprise.

Rarity lifted up her crystal, which, along with her necklace, magically repelled all dirt so it never got dirty. Using its power, she made her mess in the yard disappear, and then picked up the hose. She could have easily cleaned herself up with the crystal - she told her friends she kept it with her for this reason in case she ever got dirty - but she liked doing this the old-fashioned way better. Of course, that didn't stop her from peeing and farting in the tub!
