The trip across the desert took way longer than Sunset expected. She could see the mountain on the other side, but it was so far away and never seemed to get closer. Fortunately, dehydration wasn't a problem here, because the desert was full of vending machines that, strangely enough, dispensed water bottles or sodas for free. So she stayed hydrated, drinking so much that she had to pee every half hour, but since no one was around to see her, she was able to just pull her shorts down and do her business without much trouble. Occasionally she'd find something to eat as well, such as sandwiches or popsicles.

The desert heat dried the drool off her, but she soon became soaked with sweat. She was thankful for all this water and soda across the desert. It would take some time getting used to this world.

She slept two nights in a row, since the trip took that long. On the morning of her second day, the cake and apple Sunset had eaten caught up with her. Again, she was able to pull her shorts down and go to the bathroom without worrying about anyone seeing her, but she had nothing to wipe with, and it felt very wet, so once her shorts were back up, her white panties felt dirty.

On the third day, Sunset finally reached the edge of the desert. She was panting and dripping with sweat. She sniffed her armpit and recoiled. She had not washed for three days, and between this and how much she had sweated, she smelled bad. It didn't help how dirty her underwear was.

She found a tunnel that led through the mountain, which came out at the swamp Wind Whistler had mentioned. The water was green and smelled worse than she did right now. The sky here was full of yellowish green clouds, probably from the stench of the swamp. Sunset walked through the swamp water, which was deep enough to submerge her entire feet and a bit above her ankles. She cringed as she felt it soak through her shoes and get her socks wet. This swamp smelled twice as bad as her stinkiest farts.

She had been walking through this foul swamp for a little over ten minutes when she suddenly felt her underwear yanked up to stretch out of her shorts, lifting her in the air. She exclaimed in surprise, blushed, and looked up to see who was giving her a wedgie.

It was Sonata Dusk. She was flying with bat wings, evidently a result of the power she and her brethren had obtained.

Sonata giggled. "I wanted to do that for SO long ever since you took our powers! Your undies look a little dirty."

"Let me down!" said Sunset, struggling against her.

"Okay!" Sonata let go of Sunset's panties, and she fell butt-first into the swamp water. Sonata giggled as Sunset became soaked in the foul-smelling water. As if she didn't smell bad enough already. Sonata flew away before Sunset could yell at her.

Sunset stood up, pulled herself back together, and continued on her way, hoping Princess Tiffany wouldn't be put off by how she smelled when she reached her. Or better yet, that it would rain and wash all this off her. This was one time she was HOPING for rain.

She found another random vending machine, this one containing 2L bottles of soda. Despite the overpowering stench of the swamp, she was thirsty, so she took one bottle of soda and drank it like there was no tomorrow, spilling quite a bit of it down her front. Then she continued to walk forward. At one point she tripped and fell facedown in the swamp water again. If there was any part of her that had been clean of this disgusting water, it wasn't anymore.

Eventually, the swamp water ended, and she could see a forest ahead. Sunset felt relieved to be getting out of this area, even though its smell would be on her for the rest of the adventure.

Just as she was stopping to take this in, she was suddenly splashed from above by fish heads, and a lot of fishy water with it. Sunset looked up to see Aria Blaze with a bucket in her hands, also sporting wings.

"Revenge is so sweet," said Aria. "And we're just getting started. Smell you later!" She flew away laughing.

Sunset groaned. She was wet, dirty, and smelled of sweat, body odor, swamp water, and fish. She could handle getting soaked in the rain, but this...

...

As Sunset walked through the forest, Adagio Dazzle watched her on a TV screen at her castle. Aria returned.

"Nice one, Aria," said Adagio. "It'll take her weeks to get both the swamp water and fish smell out."

"And now she's in our forest!" said Sonata. "The one we control with voodoo!"

Adagio dropped a Sunset doll above a map of the forest. As if by magnets, it immediately fell to the spot on the map where Sunset currently was, and moved with her. "Let me go first," she said, and she flicked the Sunset doll's butt as hard as she could.

In the forest, Sunset yelped in pain and grabbed her butt with both hands. The sirens burst into laughter at this.

"Where are you?" said Sunset, looking around as she rubbed her butt. No one seemed to be around, but she knew something had hit her rear end hard.

"Are you up for another wedgie?" said Sonata, and she grabbed Voodoo Sunset's panties with her thumb and index finger, and pulled.

"Waaaah!" Sunset was lifted into the air by her dirty underwear. She looked up, expecting to see Sonata again, but she wasn't there. This was starting to freak her out. Were the sirens invisible?

Adagio, Aria, and Sonata laughed more. Sonata was kicking her legs so much you could see her underwear (all three were wearing their original outfits), but she didn't care. Once Sonata stopped laughing, she dropped the doll, and Sunset landed on her sore behind.

"My turn," said Aria. She picked up Voodoo Sunset, and in the forest Sunset levitated into the air. Aria threw Sunset into a mud puddle, landing on her back. The mud was nothing compared to the swamp water, but it did nothing to wash it off or mask her smell.

When Sunset stood up, she suddenly felt the last soda she drank go through her, and grabbed her crotch with both hands.

"She looks like she has to pee," said Sonata.

"Perfect," said Adagio. "Sonata, hold her while we get the animals. Let's have a little fun with her."

Sonata gave Sunset another wedgie and held her in the air while Adagio and Aria took dolls of various animals, and placed as many around every tree and bush in the forest as they could. Since they had constructed these dolls, the animals were mere drones under the sirens' control, but Sunset didn't know that.

"Let me down!" said Sunset, holding herself with both hands. "I have to go to the bathroom!"

Sonata released Sunset, and Sunset ran behind a tree, but the tree branches were crawling with monkeys. Sunset didn't want to pull her shorts down in front of any animals, so she ran around looking for a bush to go behind.

She found another bush, but then a deer walked up to her, so she continued running around. The whole while her bladder became more and more full. She was already filthy, but didn't want to suffer the indignity of a pee accident.

She finally found a big tree that looked like there weren't any monkeys around it. She ran behind it, and had just unzipped her shorts when she heard a loud neighing sound, and four horses ran up to her. Sunset quickly blushed and zipped herself up again. Her shyness of peeing in front of animals went double for horses because they looked so much like ponies.

Running a bit away from the tree, she found an outhouse. Perfect! It was her only shot at some privacy so she could avoid going to the bathroom in her shorts. As she ran toward the outhouse, it suddenly moved away. She looked in the direction it had gone, and saw its new position. She ran toward it again, but then suddenly she went moving in the opposite direction.

Sonata giggled as she moved the Sunset doll while Aria had her hand on the outhouse doll.

When Sunset regained control, she ran toward the outhouse again, but it moved upwards, then fell back down in another section of forest. Sunset found it and ran at it as fast as she could, feeling the pee sloshing around inside her. But unexpectedly, she rose into the air and flew over it, landing on her butt. She ran to the outhouse entrance, but it moved again.

"Whoever you are, this isn't funny!" said Sunset, holding herself and pee dancing. "I really have to go!"

"Ooh, I wonder how long until she wets herself?" said Aria. She and Sonata continued to keep Sunset from reaching the outhouse.

Eventually, Sunset realized trying to get into this outhouse was a lost cause, so she returned to the path and ran as fast as she could, hoping to find another one.

Aria placed the outhouse near the path ahead of Sunset. Sunset saw it, assumed it was a different one, and ran for it as fast as she could, feeling she was about to burst.

But then it rose into the air, and never reappeared. Sunset groaned and continued to run.

"At this rate, she'll be out of the forest soon," said Adagio.

"Way ahead of you," said Sonata, and she started to tickle Voodoo Sunset's armpits with her fingers.

In the forest, Sunset could feel herself being tickled and started to laugh uncontrollably. Sonata only had to tickle for five seconds before Sunset started to pee full force. Sonata continued to tickle as Sunset continued to laugh and pee in her filthy shorts.

Adagio and Aria watched on their screen, and exchanged glances of satisfaction as they watched the pee run down Sunset's legs.

Once Sunset stopped peeing, Sonata stopped tickling. Sunset's laughter slowed down and stopped, and she felt her shorts. They had been wet before, but now they were warm, and smelled of pee in addition to everything else. She blushed beet red. She could not believe she had just peed herself. At least she could take a bit of comfort in the fact that it would be hard for anyone to notice with how messy she already was.

As Sunset resumed walking forward, Adagio took out a doll of a large forest monster resembling a giant pig and set it on the path ahead of Sunset.

"What's that for?" said Aria. "You know that thing doesn't attack people."

"No, but what I'm gonna make it do will be unpleasant for Sunset all the same." Adagio started to cast a spell.

Sunset found her path blocked by the monster.

"You don't want to eat me," she said. "I don't taste very good like this."

The monster didn't look like it was going to make an aggressive move. It just looked confused. Then, yellow sparkles appeared around it, and it suddenly started taking deep breaths, in the way that usually only came before one thing.

"Oh no," said Sunset.

The monster sneezed, showering Sunset with snot. The very texture of it repulsed her more than the swamp water. She could only imagine how Rarity would react in her position. The monster sneezed on Sunset twice more, each time as effective as the first. Sunset wiped the gooey substance from her face. The monster rubbed its nose, sniffled, and walked away.

Sunset continued running, wanting to get out of this forest NOW. She finally reached the forest exit, and saw the sirens' castle not far ahead. This was it. This was the end of her journey.

As Sunset ran towards the castle, Aria and Sonata suddenly flew in, wearing rubber gloves, and grabbed Sunset's arms, lifting her up.

"I hope you enjoyed our little forest funhouse," said Aria.

"And me tickling you," said Sonata.

"And that monster sneezing on you," said Aria. "You can thank Adagio for that one."

"When I get through with you..." said Sunset.

"Phew," said Aria. "She smells real bad."

"It's about to get worse!" giggled Sonata. And she and Aria threw Sunset down a manhole. She landed on her back in sewage that had her completely submerged. She sat up instantly, sputtering. The sewage smelled worse than the swamp water. She climbed up the ladder out of the manhole, to find that Aria and Sonata were gone.

Author's Notes:

The desert scene was inspired by a scene in Digimon where, after walking through a desert and taking a bath, Sora comments that they were getting pretty smelly. The forest/voodoo scene was also inspired by Puppetmon's first big episode, though there wasn't anything bathroom-related there. And the fish heads, Hey Arnold.

Don't worry, Sunset will get through it all just fine, though it will take a while to get the smell out. And she's survived worse.
