Rainbow Dash was talking to Cherry Fizzy on the phone.

"So, what's up?"

"Not much. How about you?"

"I lost a race to Indigo Zap earlier today and, because of a bet we took, I had to go into the closet with her for an hour."

"How was that?"

"I survived, but I had to rinse off cause I smelled a LITTLE more than I like to."

"I wouldn't mind going into a closet with you for an hour. Or longer."

"Hey, why don't we try that? Not tonight though. I'm sure I smell right, but I'll want to sweat and not wash for a few more days just to be sure."

"All right. Wednesday night, we'll have dinner, then go into the closet of my spare room."

"Oh yeah!"

...

Three days later, Rainbow Dash and Cherry finished dinner. Rainbow Dash had run a few races and played a few games in the summer heat, and she smelled as bad as ever.

Cherry led Rainbow Dash into his spare room and opened the closet door. It was empty. Rainbow Dash took off her socks and shoes, and they walked in, and Cherry closed the door. He opened it from the inside just to reassure Rainbow they wouldn't be locked in, and closed it again.

Almost immediately, Cherry could feel the closet become full of Rainbow Dash's smell. He inhaled deeply.

"Ahhh," he sighed. "This is wonderful. Better than the sauna at the swimming pool."

"This is much better than Sunday with Indigo," said Rainbow Dash. "Want to sniff my armpit?"

Rainbow held up her arm, and Cherry sniffed her armpit. "Mmmm, your armpit smells REALLY bad!" He sniffed again, and Rainbow Dash chuckled.

They sat inside the closet for half an hour, Cherry occasionally sniffing Rainbow Dash. Once she put her butt in his face for him to sniff. He liked the way it smelled, though he liked the smell of her armpits more.

"Hey, I'll call Rarity and see what she's doing right now," said Rainbow Dash. "Feel free to sniff me all you want while I'm talking to her. Oh, and I took my shoes and socks off for a reason."

Cherry started to sniff Rainbow's feet, savoring the smell, because they smelled just as bad as her armpits.

Rainbow Dash called Rarity's cell phone.

"Hello?"

"Hi Rarity."

"Oh, hello Rainbow Dash. How are you?"

"I'm having some fun with Cherry Fizzy."

"Ooh!" Rarity knew they were probably doing something dirty, but she didn't mind. "I'm having dinner with Twilight, Applejack, and Fluttershy."

"How's that going?"

"We just finished, but Applejack's in the bathroom because she had an accident in her shorts."

"Well, it's not the first time she wet herself!" Rainbow chuckled.

"Actually, she didn't wet herself. She... farted a little too hard, and made a big mess."

"Oh. How's she doing?"

"Oh, she's fine. It's hard for any of us to get embarrassed around each other now, but she doesn't have a change of shorts... or underwear... so she's rinsing herself off in the shower."

"How was your morning?"

"Fun. And wet." Rarity giggled.

"Awesome! Have a fun night." Rainbow hung up.

"How's she doing?" said Cherry, who laid back and relaxed, still able to smell Rainbow Dash clearly even if he wasn't sniffing her armpits or feet.

"She's doing great," said Rainbow Dash. "She's with Twilight, Applejack, and Fluttershy now."

After another half hour, during which Cherry occasionally sniffed the stinkiest parts of Rainbow Dash, she called another number.

"Hello?" came Sunset Shimmer's voice.

"Hi. I'm in the closet with Cherry. We're really loving it right now. What are you doing?"

"I'm having as much fun as you. I'm at Flash Sentry's house and I just wet my pajamas for him." She giggled. "He's just about to give me a bath in my pajamas. I asked him to spend extra time scrubbing my butt."

"Oh, he'll love that."

A loud fart was heard.

"Is it one of those times?" said Rainbow Dash.

"Yes. I'm sure I'll fart in the tub a lot, and in his face. And I'm sure he'll love that."

"Sounds like fun! Have a nice bath."

"Have a nice time in the closet."

They hung up.

An hour later, Rainbow said "I have to go pee."

"I don't mind if you go in here. I can just clean the closet floor. But if you want to get to a bathroom, go ahead."

"No, I'll stay in here with you as long as you want."

"Awesome!"

"Hey, I wonder what Pinkie Pie's up to." Rainbow called Pinkie while Cherry sniffed her feet, this time between her toes instead of the soles.

"Hi Rainbow Dash! Sonata and I just finished a REALLY fun farting contest! I won this time!"

"I wish I could've seen it," said Rainbow Dash.

"You'd probably have more fun HEARING it. You'd probably wet yourself from laughing too much."

Rainbow felt a jolt in her bladder.

"Both of us peed ourselves not even five minutes in!" continued Pinkie. "The pee was just flowing down our legs cause we were laughing so hard. So once again we were wet for most of the contest." She giggled.

"Sounds like fun." Rainbow Dash was finding it harder to hold it from Pinkie's description, but she didn't mind. "Right now I'm in the closet with Cherry. It's much more fun now than it was for us three days ago."

"I probably wouldn't want to be in his position, but he likes smelly girls so I hope you two have fun!"

Rainbow fidgeted for another hour while Cherry continued to sniff her.

"You look so cute when you have to pee," he said.

"You're really loving this aren't you?" Rainbow blushed lightly and chuckled.

"Of course."

Another 20 minutes later, she really needed to go. She had drank a lot with dinner. She probably could have held it longer, but Cherry didn't show any signs that he wanted out of the closet yet. So, Rainbow let go and started to pee right here. She chuckled as she felt her shorts grow warm and wet, and a different smell was soon noticeable in the closet.

Cherry could hear the sound of Rainbow Dash peeing, could smell it, could feel the back of his jeans get a little wet as he was sitting beside her.

"Ahhhhhh," Rainbow Dash sighed.

Cherry sniffed Rainbow's armpit again, causing Rainbow to giggle.

They stayed in the closet for another few hours. The closet was full of not only Rainbow Dash's odor, but also the smell of pee.

Eventually, it was time to brush their teeth and go to bed. Rainbow Dash didn't rinse off until tomorrow morning.

Author's Notes:

Somehow I'm finding it easier to fetishize Applejack than before, or at least EqG Applejack.

Also, if you think that Cherry would have wet himself at some point in the closet, for how many hours they were in there, he probably did. His jeans were already wet from sitting in Rainbow Dash's pee anyway.

I held back on having Rainbow Dash fart this time so it didn't interfere with her usual smell.
