You're out camping somewhere. After lunch, you go for a walk around the campsite path through the woods. You're still wearing your pajamas, you can't really see any reason not to.

As you turn a corner, you see two girls standing there talking. One has yellow skin, red and yellow hair, and is wearing a black T-shirt with a sun design on it and a pair of tight jeans. The other has purple skin, dark purple hair in a ponytail with glasses, a light blue T-shirt, and short, thick but tight purple shorts.

As you get closer, you notice these girls look very dirty, and a visible stench is emanating from them. You have a thing for dirty smelly girls like them so you walk towards them. As you get closer you can smell them.

They stop talking and turn towards you.

"You don't want to come any closer," says the redhead. "We pick the most isolated campsite for a reason."

"If you're referring to the way you smell, I don't mind," you say.

"Really?" says the redhead, sounding intrigued.

"In that case, it's nice to meet you," says the purple girl. "I'm Twilight Sparkle."

"I'm Sunset Shimmer," says the redhead.

You shake their hands, and sniff. Sunset and Twilight smell absolutely foul. You're really enjoying being near them, but you don't want to weird them out with your fetish. "Did you get sprayed by a skunk?"

"No, we just haven't washed for a year," says Sunset.

"A year?"

"Twilight and I were on a two-week camping trip. But the shower was broken and the lake was roped off because it was polluted. So we weren't able to wash the entire time. At first it was unpleasant, but we found we liked it. There was also no toilet paper in the bathroom so we haven't been wiping either. We got some dirty fun out of that, too." Sunset blushes but smiles. "So we haven't washed or wiped since we got back."

"Not washing for an extended period of time causes body odor that makes you smell really bad," says Twilight.

"Yeah, I knew that already," you say.

"When we hang with our friends we always spray air freshener in the room," says Sunset. "And when we go out, Rarity makes us wear frou frou dresses that block our smell."

"Sometimes they can take a while to get off," says Twilight. "Of course we don't have to worry about making it to the bathroom on time because whenever we need to go, we always wet ourselves."

"Yes we do," says Sunset. "I hope that doesn't put you off." FFFFRRRRRT! "And we fart a lot. But although we don't wipe, we don't mess ourselves either."

"Doesn't put me off in the least," you say. "Do you mind if I hang out with you today?"

"Not at all," says Sunset. "I like someone who doesn't mind how we smell."

"Me too," says Twilight. "There's just something about it that makes me feel..." She blushes a little.

"How would you feel if I really liked the way you smell?"

"Ooh, you have an olfactophilia fetish?" Twilight says excitedly.

"Olfacto-what?" says Sunset, a bit puzzled.

"It means you get sexually aroused when someone smells really bad."

"I like that even more." Sunset blushes and smiles.

"Sounds like we're gonna have lots of fun together," you say. You can't believe your good fortune. Here are two smelly girls who like the way you feel about them.

Twilight is so excited she wets her shorts. She blushes lightly but giggles.

"Expect that to happen a lot," says Sunset. She stretches her arms and the smell of her armpits wafts in your direction. You inhale deeply through your nose and exhale in a sigh of pleasure. Sunset and Twilight smile.

...

You hang out outside for a while before Twilight says "Want to go back to our tent?"

"Sure," you say.

"Our sleeping bag might be big enough for three," says Sunset.

"Sounds like fun."

Sunset and Twilight walk ahead of you. As you walk behind them, with their stink wave blowing in your direction, you stare at their butts. Sunset's butt looks so cute in those dirty jeans, and Twilight's butt, just as much in those tight dirty shorts. You can see small brown stains on their butts from not wiping.

Twilight farts loudly. PPPPRRRRRT! She looks over her shoulder at you with a smile, then slaps her butt.

Sunset wets her pants while walking. She sighs in relief as she does so, then slaps her butt seductively.

You enter their tent. It is pretty small, so as soon as you're inside, the tent is full of their smell. More so when Twilight closes it.

"What would you like to do first?" Sunset asks. She and Twilight stretch their arms, and the smell in the tent intensifies.

You inhale deeply through your nose, greatly enjoying the smell. "I'd like to sniff your armpits."

Sunset and Twilight walk in front of you. Sunset raises her right arm, Twilight raises her left arm, and they put their armpits as close to your face as they can. You sniff deeply, savoring every second the stench of their armpits enters your nostrils.

After about a minute of it, Sunset and Twilight grab your face and force it into their armpits. You're surprised at first, but then resume sniffing deeply. Their armpits are so sweaty and stinky and you love it.

Another 30 seconds or so later, they lower their arms.

"How would you like to give us a butt massage?" Sunset asks.

"If you don't mind us farting in your face," Twilight says.

"I'd love to," you say.

Sunset and Twilight get side by side and down on all fours with their butts facing you. You love the way they look in this position in their dirty, tight outfits.

You start rubbing Sunset's butt first. Sunset sighs in pleasure as you caress and sniff her butt simultaneously. Her butt smells just as bad as her armpits, though it's a little less body odor with the added smells of farts, pee, and poop. Her jeans feel dirty, damp, and grimy, and her butt feels so soft.

Sunset unleashes several boisterous wet farts in your face. After a particularly loud fart, you slap her butt, then you continue rubbing it. Sunset seems to enjoy the swats as much as the butt massage, and she looks like she's having fun farting on you.

After about five minutes, you go over to Twilight and start rubbing her butt. Only five seconds in, she lets out a long, loud, wet fart in your face, and sighs of relief. "I've been holding that in for the last four minutes."

"I'm glad you held it till I was right next to your rear end," you say, slapping Twilight's butt playfully. Twilight giggles and lets loose with a flurry of short, explosive wet farts as you continue to rub her butt. Her shorts are as dirty, grimy, and damp as Sunset's jeans, and while her butt doesn't quite feel as soft, you still really enjoy rubbing it.

After about five minutes, Sunset says "I have a big fart coming and I don't want it to be wasted."

"Go ahead," says Twilight. "I can wait another five minutes."

You go back to rubbing Sunset's butt.

BBBBBBBBBBBRRRRRRRRRRRRT!

Sunset sighs in relief as her long, loud, deep-pitched fart blasts you in the face.

"Nice one, Sunset," you say, slapping her butt before rubbing it some more.

You go back and forth between them for about a half hour before you stop. "That's enough butt massage for me," you say. "Although I really enjoyed that."

"Me too," says Sunset.

"Me three," says Twilight. "So what now?"

Sunset lays facedown. "How would you like your face pressed against my rear end?"

You lay facedown with your face on Sunset's butt. "Like this?" you ask. Her butt feels as good on your face as on your hands.

Sunset farts in response and chuckles.

Then Twilight sits on your head. Your head is now pressed between Sunset and Twilight's butts, equally foul-smelling and gassy. You can't think of a more fun position to be in.

"If you can smell our armpits and rear ends as close as you did, it's scientifically impossible for our smell to make you faint or vomit in any way," says Twilight.

"You know it," you say.

"In other words, Sunset, don't hold back on the farts."

"I won't," says Sunset. You can't see because your face is pressed against Sunset's tush but you're sure she's smiling.

Immediately after, Sunset and Twilight both let out a series of wet farts ranging in pitch and length. You're enjoying this position even more. As the minutes go by, you don't want this to stop. You have to pee, but you don't want to make Twilight get off you so you just pee your pajamas.

Twilight giggles. "Looks like you're enjoying this so much you don't want to take a bathroom break." She farts again.

You lose track of the time but it has to be over an hour before Twilight gets up. "That was fun but I feel like doing something else now."

You get up. You smell like farts and your pajama bottoms are wet, but you don't care, you're enjoying this way too much. "It was fun. Sunset?"

"Most definitely," says Sunset. "Before you came along, Twi would just sit on my butt and we'd fart on each other. Sometimes I'd wet myself laying down, sometimes she'd pee herself all over my rear end."

Twilight giggles. "Want to smell our feet now?"

"Sure," you say.

First Sunset and Twilight stretch their arms, and you get another whiff of their armpits amidst the stench of body odor and farts in the tent. You inhale deeply through your nose and let out a sigh of pleasure. Then, Sunset and Twilight sit down side by side, and remove their socks and shoes. More stink waves come off their feet and the smell in the tent becomes even more pungent.

You take Sunset's feet in your hands and sniff them. They smell just like her armpits. Years of walking, sometimes in summer heat, and sometimes with warm socks in winter, and not washing them once.

After about 30 seconds of sniffing Sunset's feet, you then take Twilight's feet in your hands and start sniffing them. They smell just like Sunset's feet. Twilight giggles as you sniff her feet deeply. They really do enjoy having you sniff them.

Then you start tickling Twilight's feet. Twilight starts laughing, trying to kick her legs but you hold her feet tight and tickle them while sniffing. Twilight laughs so hard she wets herself again, while a few short wet farts make their way out of her. You don't stop tickling until about a minute after she's done peeing her stinky shorts.

"That was really fun," says Twilight once she catches her breath.

"Now it's your turn, Sunset." You take Sunset's feet in your hands and simultaneously sniff and tickle them. Sunset laughs uncontrollably. You keep tickling, while keeping her feet as close to your nose as possible. As Sunset laughs, she lets out a few involuntary wet farts.

"She's gonna urinate on herself any second now," Twilight says with a smile.

Sure enough, Sunset laughs so hard she wets her pants. You stop tickling her a minute after she's done peeing.

Sunset catches her breath. "I love being tickled into wetting myself while you're sniffing my feet." She and Twilight both stretch their arms, and once again you get a very unpleasant whiff of their armpits. Well, far from unpleasant for you.

...

When it's time for bed, you examine the sleeping bag.

"Usually the two of us sleep in it," says Twilight. "But it should be big enough for all of us.

"You get to smell us up close the whole night," says Sunset with a smile.

"Sounds like a wonderful night," you say.

"I hope you don't mind how dirty the sleeping bag is inside," says Sunset. "We've been laying in it in our filthy state several times, and peeing in it."

You respond by climbing into the center of the sleeping bag. Sunset and Twilight smile and climb in on either side of you. You're really enjoying being in this dirty sleeping bag between these two dirty, smelly girls.

"If you have to go to the bathroom, you can do it right here unless you really don't want to," says Sunset.

"I'm going right now," Twilight says as a hissing sound comes from her and the inside of the sleeping bag feels wetter. All three of you laugh.

Then Sunset and Twilight stretch their arms. With their armpits on either side of you you're smelling them full blast again. They fart several times, even after they fall asleep. You stay awake for a little while longer, but eventually, the sauna of their foul smell inside this tent soothes you into falling asleep as well.

...

You wake up to a hissing sound on either side of you and a very wet feeling. At first you think you're wetting the sleeping bag, but then you realize you're not peeing, and both Sunset and Twilight are. They're smiling and sighing of relief as they sleep. And you join right in, peeing your already wet pajamas.

Eventually Sunset wakes up. She stretches her arms, giving you another whiff of her armpits, and farts, waking Twilight up.

Twilight giggles. "Did we wet the bed again? It's hard to tell." A sputtering wet fart makes its way out of her.

"You did," you say. "And then I wet my pajamas while awake."

Sunset and Twilight giggle.

"How long are you here for anyway?" Twilight asks.

"Two more days," you say.

"Two more days of fun," says Sunset.

"And even after we're done here, we can hang out at your place or ours," says Twilight.

You have more fun sniffing Twilight and Sunset's armpits, butts, and feet, while giving them butt massages and having them sit on your face and fart. Sometimes Twilight and Sunset swap positions so your face is on Twilight's butt and Sunset sits on your head. All of you only use the bathroom to take a dump, and don't wipe.

You don't change out of your wet, smelly pajamas until the camping trip is over.
