Author's Notes:

Done by request, exactly as she was in The Adventures of Smelly Rainbow Dash.

You love seeing Rainbow Dash compete in sports. But there's an athletic girl you like even more.

Her name is Indigo Zap. She's always wearing a dark purple T-shirt and a pair of black compression shorts that go about halfway to the knees, and they always look pretty dirty. Everyone often avoids her in all her sports whenever possible, and when running a race, they never stand directly downwind of her. Not even Rainbow Dash, even though Rainbow Dash always beats her at races.

One day you're about to head home after a race when you spot Indigo Zap chugging down a bottle of soda. You walk up to her.

"Hi," you say. "I'm Anon. I'm a really big fan, even if you didn't win."

"Thanks," she says. "But you don't want to go near me."

"Why wouldn't I?" You get closer and immediately you catch a foul smell.

"I tried to warn you," she says. "I only wash once a month, without soap or shampoo. So I smell real bad, and I'm proud of it!"

"Is that why everyone stays away from you?"

"You know it!"

"Well, I really like smelly girls." You blush. Did you really just say that out loud? You hope she's not weirded out.

"Oh, you do?" Indigo grins. "Sounds like we're perfect for each other!" She farts loudly, chuckles, and scratches her butt.

You sniff deeply, now you know she's comfortable with it. "When's your next wash? Or rinse, I guess"

"Five days from now. But if you really want to hang out with me, you'll have to pass a test first."

"What kind of test?"

"Smell my armpits. If you can do that without passing out, I'll know you can handle my smell."

"Bring it on," you say, feeling excited.

Indigo raises both her arms, and already the smell emanating from her intensifies, with visible stench coming off her. This only makes you more excited. Your heart pounding rapidly, you sniff Indigo's armpits. It is the most foul thing you have ever smelled, including manure. And you love it. Such a rancid smell coming from an attractive girl like her. You sniff deeply and let out a sigh of pleasure.

"Heheh, you're the first to ever sniff my armpits and not pass out," she says. "You definitely got what it takes."

"Like I said, I love smelly girls."

"How about we go to my place and hang out?"

"Sounds good."

As you walk to Indigo's house, you stand behind her so you can always smell her. She lets out a wet fart along the way, and occasionally scratches or pats her butt, which you can't help but stare at.

You enter her house, which is surprisingly clean for a dirty, smelly girl like her.

"How would you like to give me a butt massage?" she asks, slapping her rear end seductively.

"I'd love to."

"If you don't mind me farting in your face. I'm usually really gassy." She chuckles.

"That'll just make me like it even more."

She gets down on all fours. "Then what are you waiting for?" She slaps her dirty butt again.

You start massaging her behind. You take a deep sniff. Her shorts smell heavily of body odor and sweat, and also a few other unpleasant smells. "Do you mess yourself?"

She chuckles. "No, but I don't use toilet paper either."

"Those shorts have got to be REALLY dirty." You rub her butt harder and harder. Her shorts feel so dirty and grimy and damp.

She lets loose with a flurry of short, wet farts in your face. You take immense pleasure in each one, occasionally giving her butt a playful swat after a particularly loud fart, which she seems to enjoy as much as you.

After about seven minutes, she says "Ok, that's enough."

You stop. "Did you like that?"

"I loved it. And I can tell you did too. How would you like to smell my feet?"

"Would I!"

She gets into a sitting position and pulls off her shoes and socks. More visible stench comes from her feet, and you immediately sniff them up close, once again inhaling deeply through your nose. They smell just as foul and pungent as her armpits.

"Like my armpits, no one else can smell them and not faint," she says.

You sniff her smelly feet for a few minutes before she wets her shorts, sighing in relief.

"Do you do that all the time?"

"Yes. It's more convenient than having to find a bathroom, which I only have to do if it's number two. Besides, I like being really dirty."

"I certainly don't mind." Now you know what that other smell on her shorts was, besides the ones that came from not washing or wiping.

Once you're done sniffing her feet, you say "Do you mind sitting on my face?"

"Lay on your back and find out," she says with a smile.

You lay on your back, your heart pounding rapidly. Indigo sits on your face. Immediately your face is pressed against her dirty, grimy, smelly rear end, with her wet, dirty, stinky shorts. You breathe in deeply through your nose and give her a thumbs up.

"Tap me three times when you've had enough," she says. She farts on you several times, all of them boisterous and wet, and you love it so much you don't want to stop.

After about ten minutes, you decide you've had your fun, so you tap her three times and she stands up. "Did you like that?" she said.

"I loved it," you say. "You've got the cutest and smelliest butt of anyone I know."

"Thanks." She chuckles, then turns around, sticks out her behind, and farts again. You slap her butt, and she giggles.

Then you watch a movie with Indigo, sitting beside the smelly girl as she farts several times. Then she orders takeout from one of your favorite restaurants.

"Want to sleep over?" she asks once you're done eating.

"Sure," you say. "In fact, if you want, I could get a sleeping bag for the two of us that can mostly close from the inside, so it'll be full of your smell.

She chuckles. "Do it."

...

So you go out and pick up the sleeping bag, along with your pajamas, and that night the two of you climb into it, and you close it, so that you're laying inside the sleeping bag with the smelliest girl in the world.

"Are you having as much fun as I am?" she asks.

You inhale deeply through your nose. "Do you have to ask?" you say.

She gives you a whiff of her armpits, which you take great pleasure in. Then she lets out a long, loud, deep-pitched fart.

BBBBBBBBBRRRRRRRRRRRRRRRRT!

"Ooh, did you soil yourself?" you ask.

She feels her butt. "No, my underwear's no dirtier than usual. Which isn't saying much." A shorter, wet fart makes its way out of her and you pat her butt lightly. "You don't mind if I wet the sleeping bag, do you?"

"Not at all."

Indigo starts peeing, giggling and sighing in relief. You can feel the wetness get near you but you don't mind. You cuddle Indigo in her wet, smelly state, before the two of you fall asleep.
