Rarity was in her dress shop trying hard to finish her spring line in time to get them on her store's shelves. She ran to and fro across her store as fast as she could grab supplies. She was making good time. Until, she tripped and fell right on her face. She turned around to find a white and pink backpack laying around her boot.
"Ugh, Sweetie Belle!! How many times have I told you don't leave your backpack on the middle of the floor!"
"Sorry sis." Came a younger voice from the top of the stairs, Sweetie Belle came running down to aid her sister. "I didn't mean too. I had to go to the bathroom really bad when I got home and forgot about it. You okay?"
"Yeah, I'm fine, just be happy I wasn't carrying my scissors or safety pins." Rarity chuckled slightly. Then, from the otherside of the room Rarity's phone vibrated.
"You got a text, Rarity." Sweetie Belle informed her sister.
"Who's it from, dear?" Rarity asked. Lost in thought while continuing on the dress she was working on.
"Rainbow Dash, she says she needs your help with something important." Sweetie Belle read.
"Tell her that I'm currently a little busy but I can come over later." Rarity instructed. Sweetie Belle deciding she was all ready in enough trouble with her sister, she listened to her and responded to the text. About two minutes later,
"Hey Rarity, Rainbow responded." Sweetie told her.
"Well, what did she say?" Rarity asked..
"If you come over now, I suppose I'll try on a some of your dresses." Sweetie Belle finished reading. "Whatever she needs help with, she must need bad to make a deal like tha... Rarity? Where the.."
"I'll be back soon, dear. If you need anything to eat check the fridge." Rarity said running by her with a bunch of dresses in hand.
"Wait, Rarity, your phone." Sweetie yelled to her. Rarity stopped and quickly ran back to grab it, with her hands full, Sweetie Belle placed the phone into Rarity's mouth.
"Mmank youmm" she tried to speak before running out to her car and tossed everything in the back seat.
Wow, your sister is a spazz." Scootaloo said as she stood watching the whole thing from the upstairs.
"Were you watching that whole thing?" Sweetie Belle asked.
"Well, it's not like we had an thing else to do while you were down there." Scoots replied.
"Just get back up there." Sweetie Belle said chasing her friend back to her room, shutting the door.

Rarity drove through the town and finally arrived at Rainbow's house. It began to rain quite hard, but with her hands full, Rarity walked to the door and knocked, it wasn't long till Rainbow opened it.
"Come in, come in." Rainbow said.
Rarity walked in and sat the dresses neatly against on of Rainbow's Chairs
"Now Darling, what did you need help wi..Rarity began just as Rainbow grabbed the necklace. Casting the spell on Her.
"Rarity, you okay?" Rainbow asked making sure the spell worked.
"Of course darling, what can I help you with?
"Hmm, let's head over to the couch." Rainbow said. Rarity made her way to the couch.
"Woah, that was even easier then last time." Rainbow remarked following Rarity to the couch.
"Alright Rarity, let's just get to it." Rainbow began. "What are your fetishes?
"Well" Rarity began softly. "This whole prissy, "I have to be fabulous in front of everyone." isn't who I really am. Basically, my fetish is I absolutely love to get down and dirty" she said with a huge smile on her face.
"Woah, she keeps that act up pretty damn well then." Rainbow thought to herself. "So what do you mean by getting down and dirty? Like how dirty." Rainbow asked.
"Well, it's not really what you would think." Rarity said. "Basically i'll take anything that'll get me messy. But I think one of my favorites is having my head dunked in a dirty toilet. Something about it just gives me such a rush."
"When you say dirty toilet, do you mean one that just hasn't been cleaned? Or one that's been... used?" Rainbow asked
"Well, both really. Mostly ones the have been used because part of my other fetishs are pee, mud and even though I hate to talk about it manure." Rarity said blushing bright red.
Rainbow Dash honestly didn't know what to say. One of her closet friends had such a dirty secret for so long.
"Does.. Does anyone else know?" Rainbow asked curiously.
"Only Applejack and Twilight. We get together once a week and have some fun together." Rarity said quietly. While she was still quite surprised by the whole thing. Rainbow was, of course, intrigued in trying it out.
"Well, I guess it's worth a shot. I have to go to the bathroom anyway so I guess I'll go get us started" she said nervously and walked into the bathroom and shut the door and leaned against it.
"Something tells me, this is going to be the best one so far." She walked over to her large toilet bowl, pulled down her panties and began reliving herself.. Of everything.

About five minutes later, Rainbow had finished and called Rarity into the bathroom. It smelled really bad. But nether girls seemed to care. Rainbow shut the door and locked it.
"Alright" she told Rarity. "Show me what to do."
"Well normally, I would leave all my clothes on but also normally do this in my own toilet." She chuckled bending down towards the toilet.
"If you feel like taking off your clothes then go a head and do it." Rainbow commanded. Rarity smiled and did as she was told, she took her shirt and bra off. Then she sat on her knees infront of the filthy toilet. The smell would make anyone throw up right there and then. But to Rarity, she really didn't mind.
"Well, what are you waiting for? Asked Rainbow ordered in a teasing voice. "Get your beautiful self, filthy."
Rarity looked down at the filthy toilet water below her.
"As you wish, my dear." Rarity said, she held her breath and lowered her head down into the water. An audible "squelch" was heard as Rarity splashed her head around in the dirty toilet. Rainbow leaned in to get a better look. There was just something kinda sexy about seeing her "clean and proper" friend just getting so filthy.

About a minute later Rarity lifted her head out of the toilet. Her perfect purple hair was now a sopping mess with brown water cascading along her chest and over her breasts.
"Oh my darling, that felt so amazing. What a rush." Rarity said as her filthy hair fell into her face. Rainbow blushed, deep down she really wanted to give it a shot. Just then Rainbow suddenly felt the need to pee.
"What's wrong, dear?" Rarity asked sweetly. Filthy water still dripping down her body.
"It's just. I really have to pee." Rainbow said. Rarity smiled.
"You could wash me off." She giggled and winked. Rainbow thought for a moment.
"Oh.. Rainbow thought for a minute. Then she realized what Rarity had meant. "Sounds like a great idea." Rainbow replied with a slight smile on her face.
"just hop in the tub." Rainbow commanded.
Rarity did as she was told. Rainbow was now standing above her. Under her skirt, Rarity noticed Rainbow's blue panties were still on.
"Aren't you going to take those off? Rarity asked pushing her dirty hair out of her face again.
"Nah, I wanna try something different." Rainbow said quickly, not realizing what she said.
"Different?" Rarity asked. Suddenly it hit her what She said.
"I um.. Uh.." Rainbow blushed and stuttered trying to think of an excuse.
Rarity just giggled.
"Don't worry, we all pee in the shower every now and then. No need to be embarrassed about it" Rarity replied still giggling.
"Uh, alright then. Rainbow said, regaining her composure. "Anyway, ready for your wash?" Rainbow asked.
"Oh yes" Rarity responded as more dirty water splashed down her body.
"Alright, let's do this." Rainbow said.
Rainbow began to relieve pressure from her bladder. Rainbow quickly began to have a warm feeling in her panties as they darkened. Rarity closed her eyes and waited. It didn't take long for the yellow liquid to seep through her panties and began to splash onto Rarity's head washing away the filthy mess from the top from her head. It slipped along her face and dripped onto her bare chest. Rarity was enjoying this immensely. She was splashing and giggling the whole time not as much as Twilight had though. At last, Rainbow's stream stopped falling on Rarity. Though Rainbow was still peeing a little in her panties. She couldn't help but actually enjoy it.
"Feels kinda nice and warm, kinda like a normal bath.
"That was lovely, Darling." Rarity said snapping her out of her trance.
"Yeah, it was." Rainbow replied as her stream cut off. Rarity was now mostly clean except the pee that now dripped off her.
"So, what now darling?" Rarity ask sweetly. Rainbow looked at the toilet that was still a mess after Rarity's escapade.
"I..i think I'd like to give it a try." Rainbow said quickly. Rarity giggled.
"You wanna add another color to that hair of yours?" She joked. Rainbow chuckled too.
"Sure, why not. It seems like it would be fun to at least try." Rainbow responded.
"Well, go on then." Rarity coerced.
Rainbow looked down at the filth below her. She thought for a second, took a deep breath, a began to take off her shirt.
"Why do I have the feeling this isn't going to be the most disgusting thing I'm going to try with this necklace." Rainbow thought to herself as she tossed her shirt and bra to the side. She bent down on to the floor just inches from the toilet bowl. She took another deep breath, as she did a rush of pleasure went over her and then without hesitation. Splashed her head into the filthy toilet. There were a bunch a quiet squelching as Rainbow had her fun.

Like Rarity, she didn't stay under long and about thirty seconds later, Rainbow lifted her dirty head out of the toilet. Her bright rainbow hair had turned in a dripping brown mess. Filthy water quickly dripped along her face and onto her chest and breasts below. She felt great, like Rarity had said. It really was a huge rush. Even if it was something completely gross.
"Loving the new look" giggled Rarity. Who had been leaning against the edge of the tub, watching, with both hands on her chin. Rainbow chuckled.
"I think I'm going to need a wash too" Rainbow laughed.
"Well, looks like you're in luck." Rarity said, feeling the need to pee really bad. She could already feel it starting to leak into her panties. Rainbow saw the wet mark in Rarity's panties beginning to grow. All she could do was smile. "Can't wait." Rainbow giggled back as the dirty water continued to drip.

Rarity and Rainbow switched places in the tub, now Rarity was standing above Rainbow. After holding it in for what seemed like forever, Rarity began to release the pressure in her bladder. As she did, it filled her panties quickly and came rushing through her panties onto Rainbow below. The warm liquid splashed onto Rainbow's head watching away the brown and revealed her Rainbow hair once again. Everything spilled off Rainbow's head and was soon washed away completely. But she was enjoying the wash so she was disappointed when Rarity began to cut off her stream.
"So, what do we do now?" asked Rarity putting her shirt and bra back on. Rainbow Dash thought for a moment. Listening to something.
"Rarity, what did you say the other part you enjoyed about being degraded again?" She asked.
Both girls looked at each other still dripping from their fun.
"Mud" Rarity finally said. "Playing around in mud." Rainbow didn't speak for a moment still listening to something.
"Sounds like it's still raining, you wanna go play in the mud before we get fully cleaned up?" Rainbow asked putting her shirt and bra back on. Rarity smiled, she looked like a kid in a candy store.
"Yes, yes, yes, ye.." Rarity began
"Okay, okay. I get it. Let's go have some fun." Rainbow laughed and the two walked quickly towards Rainbow's backdoor. Rainbow had been right, it was still raining pretty hard. She looked out and saw her soccer setup. Infront of it there was a large, gooey, mud puddle.
"Alright Rarity. Go play in that mud. Get as dirty as possible." Rainbow commanded.
Rarity did what she was told. She opened the sliding glass door and ran out to the mud pit flopping down and rolling around.
"I Wish she would do this all the time" Rainbow chuckled. And went to clean up.

About Twenty minutes later, Rainbow came back out to her living room. She looked outside and saw the rain had let up a bit but, Rarity was still wallowing in the mud. As she watched she remembered her end of the deal they had made. She looked over at the chair where the dresses laid neatly on the arm.
"Ugh..a deal is a deal." Rainbow groaned and walked over to the dresses and picked one out. She put it on and fidgeted with it a little so that it looked like they had been doing measurements.
"This actually looks pretty nice on me." Rainbow said as she looked at herself in the mirror. She walked back to the backdoor where Rarity was still playing. She opened the door and shouted to her.
"Hey Rarity, come back in now." Rainbow hollered. Rarity came running back to the door as Rainbow lifted her hand up to the necklace, breaking the spell on Rarity.
Rarity looked around for a minute.
"Wha.. What happened? WHY AM I COVERED IN MUD!?" Rarity yelled.
"Wow, she should get an oscar for that acting." Rainbow thought to herself. "Well you see" She began to explain to Rarity. "Our deal was I uh.. would try on some of your new stuff if.. If you played a game of um.. soccer with me since I had no one else to play with." Rainbow said trying not to let Rarity know she was, of course, lying.
"Uh-huh..." Rarity said feel a bit skeptical about it but eventually gave in.
"Well, let's go get you cleaned up a little." Rainbow said quickly before Rarity could ask anymore questions.

About thirty minutes later, Rarity was back to her clean self, her clothes though, were a different story. Her clean white shirt and perfect purple skirt were stained from the brown mud, Which Rarity wasn't exactly pleased about. They were sitting on Rainbow's couch. Rainbow had taken off the dress she had been wearing and was now back in her normal clothes.
"I gotta say.." Rainbow finally spoke up, breaking the silence. "As much as I hate to admit it. That last one we tried on, was pretty nice."
"Pretty nice? You actually liked to wear a dress for once?" Rarity replied a tad surprised.
"Yeah, looks like you might finally have another customer on your hands." Rainbow joked.
"I'll have you know, i have plenty of customers. In fact i was working on my new spring line before I came ove..." Rarity said before cutting herself off. "THE SPRING LINE! I FORGOT ALL ABOUT IT." Rarity yelled and jumped up.
"Woah, slow down there Rares.. Whats wrong."
"I HAVE A WHOLE LINE TO FINISH TONIGHT SO I CAN GET THEM OUT BEFORE THE DEADLINE!! Rarity yelled. "So sorry to leave so quickly darling, But I must simply have to go" she said quickly before running towards the door. She grabbed all the dresses from the chair. Except one.
"Wait Rarity!" Rainbow said running across the room. "You forgot one."
"Keep it darling, you said it yourself you loved it." Rarity winked as she opened the door.
"Thank you, Rarity." Rainbow said and smiled back at her.
"Ta-Ta for now, see you in class!" She said as she rush out the door to her car.
"See you then" Rainbow chuckled and shut the door. She looked at the clock. It was almost six o'clock.
"Hmm, I think I might have time for one more today." Rainbow giggled as she reach her phone out and went through her contacts once again.
"Let's see. Who's it going to be..." She asked herself. Then she stopped suddenly. "This should be interesting." She said and began to write out a message.
