Sunset's Smelly Sleepover
All characters in this story are 18+
The Sleepovers were a semi-regular occurrence within Sunset’s high school friend group. Almost every weekend she was at someone else’s house for a get together, and without fail, a number of them would end up staying the night. This weekend, it was her turn to host, and she was pretty excited as it approached.
But then, on Wednesday, Rainbow Dash informed her that she suddenly had a tournament to go to, and Fluttershy was going to tag along with her. So they were not going to be able to make it this weekend. And then, on Thursday, Pinkie Pie told her that she suddenly had to watch the Cake twins and she wouldn’t be able to come either. Well, that’s fine, thought Sunset. Things come up, and plans change.
Then, on Friday night, she got another call.
“Hey, Sugarcube,” Applejack’s voice came apologetically over the phone. “Rare’s and I aren’t gonna be able to make it this weekend, sorry. I’ve got a lot of work to do and Rare’s gotta look after her sister for a few days. We’ll make it up to you next time.”
Sunset smiled softly into the phone. “Hey, no, that’s okay,” she said. “It’s no biggie. It’ll just be Twilight and I tonight I guess.”
“Really sorry about this, Sunset.”
“No, don’t be,” Sunset affirmed. “It’s fine, things come up. We can get together next time. Have a good weekend.”
“Yeah, you too, Sugarcube.”
Sunset pocketed her cellphone with a sigh. Oh well. Looks like it was just going to be Twilight and her this time around. That wasn’t the worst thing ever. While she didn’t like to rank her friends or anything, she really did enjoy spending time with Twilight the most. They had an… interesting thing in common, to say the least.
And you know, maybe Sunset had a small, teeny-tiny crush on her too, but that didn’t really matter. Did it?
She shot Twilight a quick text to let her know of the updates, and then went to place the take-out order for Taco-Bray for pick up. Hopefully this time they’d remember everything in the order.
Twilight was waiting outside her front door when Sunset came back with the food, and she let the both of them inside. “Hey, Twi! Glad you made it!” she said cheerfully as she set the large bag down on the counter.
“Yeah, of course, Sunset!” Twilight replied. “It’s a shame about the others though. But, we do this often enough. We’ll probably just see them next week!”
Sunset nodded. “Yeah, that’s what I told AJ,” she replied as she started emptying the bag.
“So, what’d you get for us?” asked Twilight curiously. Sunset smiled as she set a few things down in front of the other girl.
“Oh, only your favorite order,” she said playfully. “Two cheesy bean gordita crunches, with the doritos shell, one cinnaBonBon delight, and some cinnamon twists!” She gestured to each wrapped item in turn. “Annnnnd,” she said, miming a drum roll as she pulled out two more wrapped items from the bag. “Two breakfast bean burritos for tomorrow morning!”
Twilight grinned. “Holy cow, you went all out!” she exclaimed.
Sunset turned to put the two burritos in the fridge for tomorrow, and to also conveniently hide her small blush as she replied, “Of course. Anything for you!”
The two of them dug in, quickly devouring all of their food and transitioning to the living room to binge watch some Neighflix. They got through almost three whole movies before they realized it was almost two am.
“Oh wow, that time flew by,” commented Twilight with a laugh. “I don’t know about you, but I’m ready for bed.”
Sunset nodded. “Yeah, same.” They cleaned up their mess and shut the television off.
“Hey,” Sunset began. “I didn’t bother taking out any of the sleeping bags because it was just us. I figured we could just share my bed, if you don’t have a problem with that.”
Twilight shook her head. “No of course not,” she affirmed. “It was my turn to sleep in the bed this week aways,” she added with a smile.
Sunset smiled back as she headed to her bedroom, and she tried to calm her increased heart rate. Calm down. You’re just friends sharing a bed, you do this every week, Sunset.
It didn’t take long to get ready for bed, and soon they were settled in. “Good night, Twilight,” said Sunset as she turned off the bedside light.
“Good night, Sunset.”
Silence and darkness settled over them as they slowly started to drift off to sleep. But then, Twilight shuffled under the sheets as she felt something stirring in her rectum.
The girl blushed as a burst of warm gas suddenly slipped out of her ass with a low trumpeting noise. She glanced over at Sunset as the rancid air hit her nose. The other girl’s face imperceptibly twitched as the scent made its way over to her, but otherwise, she said nothing. Twilight shifted in her seat, embarrassed by her fart. The worst part was, she could feel more gas brewing inside her gut, waiting to spew out.
Crap, thought Sunset as she watched Twilight stir out of the corner of her eye after another quiet fart. The scent of her anal air once again passed over to Sunset, and she did her best not to react to the foul fumes. She could also feel a stirring in her own bowels that was likely to make an appearance soon as well. Maybe Taco-Bray wasn’t such a good idea.
It was a gassy night, with the two girls not acknowledging each other’s flatulence and trying to sleep. In the morning, both were hesitant to tackle their burritos, but their hunger eventually won over and they ended up scarfing them down with some fresh coffee.
“What do you want to do today?” asked Sunset as she finished her coffee.
Twilight shrugged. “I don’t know. We could watch the sequel to that movie we watched last night, it was pretty interesting,” she suggested. “Plus I don’t really feel like going anywhere today.”
Sunset nodded. “That sounds like a plan!” she said as she put both her and Twilight’s dishes in the sink.
They went back into the living room and collapsed on either side of the couch to watch their movie. The two girls watched in silence, sipping on their second cups of coffee, and each recognizing an unmistakable discomfort growing in their colon.
Twilight lifted up slightly to let a silent whiff of gas slip out in an attempt to lessen the pressure in her rectum. Another quiet toot followed, and Twilight flattened her butt back against the seat in shame.
Suddenly, the raucous noise of a wet, crackling fart pierced the silence in the room, and Twilight cringed in embarrassment for a moment before she realized it hadn’t come from her. She hazarded a glance over at the girl sitting next to her, and saw that Sunset’s face was a deep pink.
“Sorry,” she muttered out as she noticed Twilight looking at her in shock. “I guess the Taco-Bray didn’t agree with us last night.”
“Y-yeah,” replied Twilight. “I guess not.”
They turned their attention back to the television as best they could, but it was hard to focus with the pressure building in each of their intestines. Tiny, quiet farts interrupted the movie’s dialogue every so often, and the scent made it hard for either girl to fully focus on the film.
Gradually though, as Twilight tried to stifle her farts, Sunset’s seemed to be getting louder. She lifted her ass up off of the couch slightly, and let another one rip. This one was loud and wet, and Sunset grunted as she forced the air out of her rectum. Twilight’s face was beet red as she stared at the offending ass. “A-are you trying to make them louder?” she asked incredulously, and she waved a hand in front of her face as the putrid stench drifted over to her.
The fiery girl next to her grinned. “What? Are you jealous that yours aren’t this loud?” she asked. Twilight opened her mouth to reply, but was quickly cut off by Sunset. “Why don’t we see how loud you can get?”
“How loud I can get?” Twilight echoed. “Sunset, that’s gross!”
Sunset just smiled as she let another toot out of her butt. “I mean, we’re already gassy beyond belief. Why not just have a little fun with it?”
Twilight frowned slightly. “Isn’t that really childish though?” she asked quietly.
“Oh, comeon Twilight! It’s just the two of us! No one else will know,” Sunset urged. “Plus, it’s fun to be a little childish every now and again.”
Twilight sat there in silence for a moment, a look of distinct discomfort across her face. Sunset realized that the other girl probably found this really gross, and her own face grew slightly redder in embarrassment. She straightened back up, planting her butt firmly on the couch. “Hey, listen-” she started to say but was cut off by a fairly loud sputtering burst of flatulence from beside her.
She looked over and saw Twilight looking at her as she leaned to the side, a deep red blush on her face. “How was that one?” she asked nervously.
Sunset grinned. “Not bad,” she commented. She lifted her own ass and let another fart rip, and the vibrations reverberated into the couch.
The two of them continued at this throughout the next section of the movie - each of them trying to one up the other in the boisterousness of their farts. The room was getting stinkier with each burst, and Sunset secretly loved it.
The truth was, Sunset had a bit of a bathroom fetish. Not a large one, she didn’t want someone to like crap all over her or anything, but she enjoyed watching girls fart and poop. Especially when they were really gassy.
Twilight didn’t seem to be too bothered by the stench either, which was a relief. She was glad that her friend wasn’t disgusted by her little competition, and it led to a spark of hope in her chest that maybe Twilight had a similar fetish as hers.
Their little game continued for a while, the two girls trading farts for several minutes. At one point, they even got a little bit more competitive. Sunset stood up and angled her butt towards Twilight’s face and let it rip, farting loudly in her friend’s direction. Her ass was only a few inches away from the other girl’s head, and she could feel the light breeze that came from it.
“Oh, now you’re just playing dirty, Sunset!” complained Twilight as she too stood up and turned around to squeeze out another fart back in the redhead’s direction.
Sunset was torn out of her playfulness as she ripped out another fart, though. It was wet and rancid, and Sunset’s face went crimson as she felt something semisolid squirt out of her butthole and into her pajama bottoms. It made a disgusting squelch as it filled her panties, and Twilight turned to look just in time to see a light brown stain begin to spread out from around the seat of her pants.
“Uh…” the purple girl balked. “Do you, uh, need to use the bathroom?” she suggested. Sunset, her face still red, just nodded silently. Twilight’s eyes were still locked on her butt as she made to stand up, but then she paused as the other girl’s face began twitching slightly before Twilight burst out in a fit of uncontrolled giggled.
“Uh, Twilight?” Sunset asked, an uncertain smile on her own face. “You good there?”
Twilight waved a hand in the air as she tried to rein in her laughter. “Y-yeah I’m g-good,” she managed to stammer. “I don’t know why its so… so f-funny!” She was barely able to finish her thought as she fell into another fit of giggles.
Then, because karma is oh so sweet, (or should Sunset say stinky?) Twilight's laughter quickly petered out as her giggled loosened her own rectum and she let a similar wet shart fill her own shorts.
Now, Sunset began to chuckle as the other girl covered her mouth in shock, her eyes wide as she looked up at Sunset. “Oh-ho, that’s too perfect!” she chucked maniacally as she held her stomach. Her own anus trembled again as she laughed, and it was futile to try and hold in the few extra spurts of shit that slipped through her loose butthole.
“S-sunset, I really think we need to get to the bathroom,” Twilight urged as she struggled to both hold in her poop and stop laughing.
“There’s only one,” Sunset replied. “But I have an idea, follow me.”
Twilight didn’t even have time to question what they were going to do as Sunset walked over and pulled on her arm. She struggled to keep her bowels in check as she stood up - a task that was far more difficult than she thought it should be - and she was dragged through Sunset’s kitchen.
Sunset opened the sliding door to her modestly-sized backyard and ushered Twilight through. “Sunset, what are we doing out here?” she asked nervously as she glanced around.
The other girl turned to face her and smiled. “Twilight, I’m going to teach you how to be a pony,” she said, before she bursted into another fit of giggles.
“Sunset…. W-what?” Twilight asked bewildered. She blushed a deep red as she watched the other girl slowly shimmy out of her pants. Her eyes locked into the deep brown semi solid sludge that was nestled in the crack of Sunset’s panties as she pulled them down. “You’re not serious are you? What if someone sees us?!”
“Look around, Twilight” Sunset replied as she turned her pants over, allowing the wet fecal matter to fall out with a dull plop. “There’s a high fence all around, no one can see us.”
Sure enough, Sunset’s backyard was lined by a tall, wooden fence. Twilight couldn’t even see any of the neighbor’s houses. “A-are you sure?” she asked timidly, looking back at Sunset.
“Of course. We’ll be fine, Twi,,” Sunset replied as she turned back around. Twilight somehow managed to blush even deeper as Sunset had walked over to the small stone patio to place her clothes down. The action caused her to bend over, fully exposing her bare ass to the girl behind her.
The pale, golden cheeks parted slightly, allowing Twilight to peer in between them and see what a mess Sunset had made of herself. Clumps of wet shit clung to the girl’s pucker, and spread out around in a rough oval. She could even see the plump wet lips of the girl’s pussy peeing out from between her thighs, and her crotch grew warm with a familiar feeling.
Well, if Sunset was going to do this, so was she.
Fueled by the sensation between her legs, Twilight yanked her own shorts down without any further hesitation. She looked at the mess in her bottoms with a strange feeling in her chest. Was this whole situation contributing to her arousal too? That was really gross. But also… hot?
Sunset squatted down then, and within moments a series of smooth semi-solid logs began to push their way out of her anus. Twilight watched with a rapt fascination that quickly grew into a strange, unfamiliar feeling of lust.
There was no doubting it, she was attracted to this whole idea. Sullying her panties and watching her friend fart and shit in front of her was turning her on.
But, as she watched the show in front of her, the urgency in Twilight’s colon could no longer be ignored. No sooner did she squat down in the grass than her ass open up to release a similar deluge of soft, long turds. The brown muck slithered out quickly into grass below her in large clumps. Twilight winced as a longer log fell down and draped against her leg, and she shifted her feet wider apart as another soft, brown serving of shit squeezed its way out of her ass.
As gross as this was, the sense of relief that came from her rectum finally emptying out was incredibly pleasurable. Her eyes fluttered shut as she forced the shit from her colon, and she let out a sigh as a stream of urine began to dribble out of her wet pussy.
The stream quickly picked up in volume, until there was a steady spray of deep yellow pee flowing into the lawn in front of her along with the torrent of blown slop still pouring from her ass on the other end.
Sunset watched as the other girl lost herself in the bliss of finally relieving herself, and a sultry smile came over her face. She made her way closer to Twilight, and then had a naughty idea. Gently, she lowered her hand so that Twilight’s stream of urine began to spray into her palm.
Twilight opened her eyes as the sound of her pee stream changed, and she looked down to see that Sunset had gotten closer and was letting the warm fluid flow over her hand. “S-sunset?” she breathed, but made no effort to either move away or stop pissing.
“Hi, Twilight,” Sunset said back quietly. “Can I tell you a secret?” The purple-haired girl nodded as the last of her shit squeezed its way out of her loose anus. Sunset leaned in closer, and put her mouth up to Twilight’s ear. “This is kind of hot.”
A bright blush adorned Twilight’s cheeks as Sunset pulled away. Reluctantly, she had to agree. There was something so wrong, so disgustingly primal about what they were doing, and her pussy was so fucking wet…
Tentatively, Twilight was forced to nod in agreement. “Y-yeah,” she whispered back. The two of them sat in silence as they gazed into each other’s eyes. Sunset idly waved her hand underneath Twilight’s pussy as the pee stream slowed to just a trickle.
“Is this just pee?” Sunset asked as she looked down at her friend’s vagina. Twilight slowly shook her head. “Or are you just as horny as I am?” A nod from Twilight confirmed this. “Can… can I touch you?” Sunset finally asked as she looked back up at Twilight.
Twilight swallowed. “I’d like that,” she breathed.
Slowly, Sunset raised her hand to brush at the swollen outer lips of Twilight’s pussy. The girl gasped as she felt another girl’s touch on her flower for the very first time. Sunset wasted no time, easily parting her labia and slipping two fingers into her dripping, wet slit.
Twilight threw back her head in a gasp and Sunset began to slowly pump her fingers in and out of her pussy.
After a few moments of this pumping, Twilight’s legs gave out to the pleasure and she had no choice but to collapse down to the ground. Her ass landed in the pile of soft, warm shit she had just produced, and the nasty muck smeared onto her bare skin. But, the pleasure Sunset was currently giving to her pussy pushed any disgust out of her mind. As a matter of fact, it may have even added to her pleasure.
A squeak made its way out of Twilight’s mouth as she came. Her body shuddered as a jet of clear fluid flew out of her parted cunt, arching across the lawn and landing a few feet away. Sunset’s eyes widened as Twilight squirted, and a wide grin came over her face as she withdrew her hand and gently helped the girl ride out her orgasm.
“H-holy shit,” Twilight gasped after a few moments. “That was…”
“Intense?” Sunset finished for her. Twilight nodded.
Sunset smiled down at Twilight. “Come on,” she said. “Let’s get you cleaned up.” She helped the girl to her feet and led her back to the house on shaky feet.
Twilight grimaced as she felt the wet diarrhea that clung to her bare asscheeks. “Damn, I really made a mess, huh?” she asked.
“Yeah, you kind of did,” Sunset confirmed with a smile. Then, her face got serious for a moment. “Did you enjoy it though?”
There was a brief pause as Twilight looked deep in thought. The silence made Sunset shift nervously, fearing the impending rejection that she was undoubtedly about to receive. But to her surprise, Twilight looked back up at her with a warm smile.
“You know, I did,” she said. “It was really gross, and I thought I was going to be really disgusted, but I… don’t feel that way at all.” Sunset’s smile grew wider as Twilight spoke. “You know what Sunset?” she added.
“What?” asked Sunset.
Twilight smiled at her. “I’m really glad the other girls canceled.”
“Ha ha, you and me both, Twi. You and me both.”
