I don't mind helping her, I just wish she didn't insist that we did it outside. It's dirty...

She was trotting along the dirt path, kicking up a light tail of dust behind her. It was midday, and there were ponies everywhere. Rarity tried to draw as little attention to herself as possible. But with ever step she took, the mud she was covered in gave a loud squelch.
"Mommy, why is that mare covered in mud?" Rarity overheard, as a small filly tugged at their mothers tail. The fillies mother quickly scolded the filly for asking stupid questions. Rarity, having attracted too much attention, began galloping, leaving big patch's of mud behind her.

She reached her boutique, magically opened the door and slammed it shut.
"This is the last time I help her!" Rarity exclaimed to herself. "Just look at me. I'm filthy." Rarity contused complaining to herself. Rarity looked around, expecting Sweetie Belle to have run into the room.
"Sweetie?" Rarity called out. There was no answer. "She's must be out with her friends." She concluded. Rarity smirk suggestively,Looks like I have the house to myself for a while. Her thoughts we cut short by a drop of mud dripping from her mane and onto her muzzle. Rarity shook her head, causing mud to be splattered across the floor.
"I'll cleaned that up later. But for now, I need to clean up." Rarity said trotting towards the stairs.

At the top of the stairs piled on top of a wicker basket was a pile of neatly folded towels, all of different assorted colours. She grabbed the top one with her magic, to avoid covering it with mud. Then, also using her magic, she turned the door knob leading into the bathroom. The floor was black and white tiled, in a checkerboard style. The walls had the same checkerboard pattern but with varies shades of blue.
"Ahhh, the one room in my house where I can get as clean, or as dirty as I like..." Rarity said out loud to herself. She placed the towel down on the counter next to the sink. The sink it's self had the usual things you would expect to see, a toothbrush holder, tooth paste and a bar of soap. Rarity trotted across the room to the curtained shower, she pulled the cream coloured curtain back and looking around the base of the shower. There was a small black dot near that drain, Rarity leaned in closer to see what it was. It moved,
"AHHHHHH!" Rarity screamed, jumping back from the shower. "SPIDER!" she exclaimed. She used her magic to turn on both of the taps causing a torrent of water to flow from the shower head. The water hit the bottom of the shower, causing water to spray ever where, but Rarity ignored it. The small black spider struggled against the flow of the water, but was swept away and down the drain.
"I hate spiders." Rarity sighed. She turned down both of the taps, slowing the flow of water. She extended a hoof out into the stream to feel the temperature. She then began adjusting the taps until she found a suitable temperature.
"Ahhh perfect." She smiled. She then stepped into the stream of water. The water flowed down onto her fur, washing away large sections of the mud.
"At the Gala, at the gala." Rarity began, singing to her self. Before she continued she tilted her head up into the water, washing the mud off of her muzzle and face. She wiped her face with her hoof, allowing her to see. She then tilted her head down washing the mud out of her mane.
"My beautiful coiffure." She said, rubbing her mane. She grabbed her exfoliation brush down from it's hook and a bar of soap from it's holder, rubbing the soap onto the brush, creating a bubble lather. Then, using her magic, she began rubbing under her shoulders and upper arms, allowing long streams of hot, soapy water run down her hoofs and draining away. After brushing away for a few seconds and one shoulder and being satisfied with how clean it is, she turned putting it into the showers stream and allowing her to begin cleaning the opposite one. She continued to clean her hooves until both were spotless.
"I expect nothing less than perfection" she announced to herself, admiring her own work. She rinsed the mud off the brush and lathered it up with soap again.

She levitated the brush down to her flank and began to gently massage her rear as well as wipe away the dirt. After a few seconds she turned her body around, putting her flank into the stream. She then put the brush on her underside to allow her to clean under her hind legs. She started from her forehoof and slowly brushed straight down. The brush went straight over her pussy, sending a shudder of pleasure through her body.
"Oh...my..." she gasped. She repeated the same action as before, just over her pussy. She let out a small moan of pleasure.
"I-I really s-should clean myself up first." she stuttered between moans. She then sat down on the floor of the shower,
"But nopony's home..." she grinned to herself. She darted her eyes around the shower seeing if there was anything she could use to pleasure herself with. All she could see was a battle of apple scented shampoo.
"Perfect..." She muttered, dropping the brush into the basin. She levitated the bottle down to herself. She popped the top open and emptied some it's contents onto her underside. Most of the green liquid slid own her body and going over her pussy. The contrast from the hot water to the cooler liquid caused her to shudder a second time.
I feel so dirty... Rarity thought to herself. She closed the cap on the shampoo and placed it down, and picked the brush back up. She then began rubbing the shampoo onto herself, creating bubbles that obscured her view of herself, but she didn't seemed to care. She then worked her way down her body, reaching her pussy.

Rarity began slowly caressing herself with the brush, panting slightly. She brushed from the top to the bottom vey lightly causing her juices to flow out and mix with the water and bubbles.
'I still feel dirty." She said, biting her bottom lip. She caught her clitoris with the brush and let out a loud, panting moan. She dropped the brush again, her magic just wouldn't last her. Rarity looked down to try and find the brush, but instead she just stared at the shampoo bottle. She reached over and took the bottle flipped it around so the cap was facing away from her and grinned...

She slowly inched her hoof towards herself, the water still pouring away onto her back washing away most of the bubby lather. She could see herself again. She inched the bottle against her pussy and began rubbing it up and down, moaning slightly with each movement. After a couple of seconds of rubbing it against herself, she positioned the bottle towards the middle of her vagina and began to insert the bottle inside. She was biting her lip as she slowly inserted the bottle, she could feel ever inch of it slowly making it's way inside of her. She let out a deafeningly loud moan and she got the half way. Rarity could feel her forelegs about to give way, she just couldn't support herself. She released the bottle with her hoof, allowing to slide out slightly. The bottle was quickly stopped by her magic. She then laid fully down in the basin, rolled over, exposing her underside to the shower. Using her magic, she began to slowly force the bottle in and out of herself. She closed her eyes, imagining it was one of her previous coltfreinds. The first one to come to mind was Big Mac, wit hit being apple scented after all.
"Oh Big Mac, YES! She screamed, pushing the bottle deeper and faster into her pussy. It became easier.
"YES, MORE! FASTER!" she yelled at her imaginary stallion. She was now taking the entire bottle inside herself, cap included.
I think the whole town can hear me. She thought, not stopping. She could feel herself about to climax, until the curtain was pulled away. Rarity climaxed, covering the section of the basin in her ejaculate. Rarity, still panting, slowly turned her head around,
"Well, aren't you a naughty little mare..."
