Fluttershy led Rainbow Dash, Rarity, Sunset Shimmer, and Pinkie Pie into her bathroom.
Rainbow Dash, Pinkie Pie, and Rarity were covered in mud from head to toe. Rarity had accidentally fallen into a mud puddle at the park, and Rainbow Dash and Pinkie Pie had jumped in to play in the mud with her, partly trying to make her feel better.
Sunset had accidentally sat on a pie Pinkie had left on a bench, and while she had done her best to wipe off the whip cream and strawberry filling, wet traces of it lingered on the butt of her jeans.
Twilight and Applejack had stayed clean and gone home for the day.
"Now, take a seat in the tub," said Fluttershy gently.
Rarity sat at the side of Fluttershy's bathtub nearest the tap, for she wanted to be closest to the water when it was running. Sunset sat beside her, close enough that their sides were touching. Sunset didn't mind that Rarity's mess was getting on her because Fluttershy was going to wash them anyway. Rainbow sat beside Sunset, also touching sides, and Pinkie sat beside Rainbow. This bathtub was easily big enough to fit them all.
"I should probably give you a little rinse first." Fluttershy filled a bucket with warm, soapy water, and poured it over Rarity, knowing Rarity wanted it the most. It washed most of the mud off her. Though not completely clean yet, she felt better at being cleaner than she was seconds ago.
Then Fluttershy poured another bucket of soapy water on Rainbow Dash. Rainbow liked the warmth of the water as it washed most of the mud off her. Then Fluttershy poured another bucket on Pinkie, then one on Sunset just to get her hair wet, even though she was the cleanest of the four.
Fluttershy turned the bathtub faucet on. When there was no more brown in the water, she put the plug in the drain and poured bath soap under the running water.
In about a minute, Rainbow, Rarity, Sunset, and Pinkie were sitting waist-deep in a bubble bath.
"Now, how about I wash your hair first?" said Fluttershy.
"We can do that ourselves," said Rainbow Dash.
"I think it'd be fun to have her wash our hair," said Pinkie excitedly.
"I think so too," said Sunset. "It'd be fun to try something different."
"It would be kind of like going to the spa," said Rarity.
"Oh, all right," said Rainbow Dash.
One by one, starting from Rarity and working to the right, Fluttershy poured shampoo on their hair and washed it. All of them enjoyed it, even Rainbow Dash, though she wouldn't admit it.
Fluttershy did not rinse their hair yet, letting the shampoo stay for now. She took two cloths, dipped them in the soapy water, and scrubbed every inch of Rarity and Sunset's top halves, Rarity with her left hand and Sunset with her right hand.
Rarity and Sunset didn't know why they were enjoying this so much. Taking a bath fully clothed with someone washing them with soap was a fascinating new experience to them.
Once Fluttershy was done with Rarity and Sunset, she began scrubbing Rainbow Dash and Pinkie Pie. They liked it just as much as Rarity and Sunset had.
As soon as Fluttershy finished, she said "Now, if you don't mind, put your tushies up in the air."
Rainbow and Pinkie giggled, and they, Sunset, and Rarity turned around and positioned themselves with their heads just above the water, and their behinds in the air facing Fluttershy. Fluttershy giggled a bit at the sight, for it looked kind of funny.
Fluttershy dipped her cloth in the soapy water and scrubbed Rarity and Sunset's butts first. She really liked the soft feeling of both of their butts, taking a little too much pleasure out of it.
Rarity and Sunset liked it. They couldn't describe the pleasure they got out of the new sensation of their rear ends being brushed with soap by someone else.
After scrubbing for a little longer than she had intended, Fluttershy lifted Rarity's skirt up and scrubbed her purple panties. Rarity let out a little squeal, but didn't try to fight it, for she took a naughty pleasure in this.
Then Fluttershy set the cloth aside, put a lot of soap on her hands, rubbed them together, and started massaging both their butts by hand. Rarity and Sunset let out sighs of pleasure, though not overly sexual.
When Fluttershy moved on to Rainbow Dash and Pinkie Pie, Rarity and Sunset resumed their sitting positions facing her. Fluttershy scrubbed Rainbow Dash and Pinkie Pie's butts, using her cloths again. Rainbow and Pinkie giggled, finding the sensation, or perhaps the situation, to be funny. Their butts were a lot more firm than Rarity and Sunset's, but Fluttershy still liked washing them.
She then massaged their butts with her hands, again using soap, all three enjoying it greatly, and when she stopped, they sat back down in the tub.
"Now, lift your feet up so I can wash them."
The girls did so.
"And... if it's all right... take your shoes and socks off."
The girls removed their footwear, turning their shoes upside-down to pour the water out. Fluttershy took her cloths and rubbed Rarity and Sunset's feet first, along with their lower legs. But, she spent a lot of time on their feet, carefully scrubbing between their toes. She couldn't help but notice Rarity's panties were visible in her current position, but Rarity didn't mind.
Then Fluttershy started washing Rainbow and Pinkie's feet. Rainbow and Pinkie started to laugh.
"Cut it out!" said Rainbow. "I'm ticklish!"
Fluttershy scrubbed their feet as thoroughly as she could, managing to wash between their toes, but she was tickling Rainbow and Pinkie so hard that they splashed wildly in the tub.
"There you go, I'm done," said Fluttershy, who was now just as wet as the other girls from all the splashing.
"Oops... Sorry, Fluttershy," said Pinkie.
"It's all right." Fluttershy sniffed Rainbow's feet. "The only thing I can smell on them is soap." She licked Rainbow's foot playfully, causing Rainbow to laugh and splash her again.
Fluttershy filled her bucket of water, this time without soap, and poured it once each over Rarity, Sunset, Rainbow, and Pinkie, rinsing the shampoo and soap off them.
"You know, darling, there's enough room in here for one more person," said Rarity.
Fluttershy took the hint. She stepped into the tub while Rainbow and Pinkie moved sideways to make room for her. Fluttershy sat between Rainbow Dash and Sunset.
Rarity lathered Fluttershy's hair with shampoo, while at the same time, Rainbow and Sunset took the cloths and scrubbed her. Fluttershy enjoyed this as much as the other girls had. She had secretly dreamed of this for a long time, just as she had dreamed of being a rabbit's pet.
Once Rainbow and Sunset finished scrubbing, Fluttershy raised her butt in the air, shaking it playfully in Rainbow Dash and Pinkie Pie's direction. Rainbow and Pinkie put some soap in their hands and rubbed Fluttershy's rear vigorously. Fluttershy sighed, taking great pleasure in this. Then Pinkie lifted her skirt and started rubbing her pink panties with soap. Fluttershy blushed lightly, but giggled.
When her butt massage was done, Fluttershy sat back down facing Rarity and Sunset, and raised her smelly feet, resting them on Sunset's knees. Rarity took Sunset's cloth and scrubbed Fluttershy's feet with it. It tickled slightly, and Fluttershy giggled. Rarity washed Fluttershy's feet as thoroughly as Fluttershy had done to her.
Then Sunset tickled Fluttershy's feet, causing Fluttershy to laugh and splash a little.
"Ooh, I almost forgot!" Pinkie took the bucket, filled it with bath water, and poured it over Fluttershy, rinsing her hair. Fluttershy closed her eyes and sighed in satisfaction.
Afterwards, the girls took all the soap bubbles on the surface of the bath water and covered themselves with it, enjoying the foamy, slippery sensation. Then Rarity pulled the plug in the bathtub. As the water drained, the girls continued to sit in the tub, covered in soap foam from head to toe.
When they'd had their fun, Rarity turned the hot water tap on again and placed the bucket under it until it was full. She dumped it over her head, and then filled up the bucket four more times, passing it to each of the other girls so they could rinse off one by one. When they were done, Rarity turned the water off, and the five girls stood up, sparkly clean and soaking wet.
"How would you like to go to my big shower, and the five of us shower together?" said Fluttershy.
"I'd love to," said Sunset.
"That would be awesome!" said Rainbow.
"That sounds lovely," said Rarity.
"Sounds like fun!" said Pinkie.
After a hot, relaxing shower, during which they each washed themselves with soap again just for fun, Rainbow Dash, Rarity, Sunset, and Pinkie walked home, feeling very refreshed and ignoring how wet they were. As soon as they were gone, Fluttershy dried her hair and changed out of her wet tank top and skirt into her Legend of Everfree outfit.
