"But it's supposed to be my turn with him today!" Twilight fumed, her fists clenched at her sides.
"Oh come on! You got to have him all to yourself yesterday, and the day before!" Sunset argued, raising her arms up in frustration.
As the two girls continued to yell back and forth, Spike sat on the carpet a few feet away from them, his purple tail waggling behind him. The three of them were currently in Twilight's bedroom and the two girls were having a pretty big argument over him. Well, to be more specific, it was over which one of them got to have some intimate one-on-one time with him tonight.
It was a pretty interesting position for Spike. It was also one that he felt many other boys at school could only dream of being in. Every few weeks, Twilight and Sunset would take turns having him rut them silly for a few nights. Twilight eventually ended up created a schedule they'd follow to make sure that each of them got equal time. Now, It was supposed to be Sunset's turn yesterday, but then at the last minute, she ended up being called in for work for the night. As a result, Twilight took the opportunity to have some extra fun with him herself. But now that Sunset was back the following day, she was determined to get her turn.
To an outsider looking in, they might find it strange how two girls who are as close as Sunset and Twilight, could possibly end up in such a heated debate like this. The two normally got along great with each other, never really fighting about anything at all. But apparently, this was another matter entirely. Spike couldn't really recall how this had all started, but one way or another, they'd both managed to get themselves completely addicted to his...well, his dick.
Honestly, Spike didn't really care who he got to be with tonight. But still, he didn't want this to get in the way of their friendship...
"Uhh, guys?" He finally spoke up, hoping to find a way to put a stop to the ever more intensifying argument before one of them said something they'd later regret.
"What?!" Sunset and Twilight both shouted in unison, turning towards him with fearsome expressions still on their faces. A red-hot inferno was dancing in their eyes.
"Uh, nothing!" He yelped, their looks seeming to promise a very slow and painful death. With him dismissed, they proceeded to continue their shouting match.
"Look, I know you missed yesterday, but I let you take this day, It'll throw my whole schedule out of whack!" Twilight exclaimed.
"Then just make a new one! You already broke it by taking an extra turn in my place anyway! When I got called in yesterday, I was dripping! You have absolutely no idea what it was like having to work like that for 8 hours straight, all while trying not to let your co-works see just how horny you are for some dog dick!" Sunset exclaimed.
"Im sorry that you've been feeling really pent up Sunset, but there is something that I really want to try with Spike tonight. I've been thinking about it all week but I've only just now built up the nerves to actually try it!" Twilight whined. She was wearing a simple pair of blue jeans and a dark purple hoodie that Sunset had bought for her a couple years ago.
Sunset looked as if she was about to say something back, but then she finally noticed the concerned looks that Spike was giving the two of them. Pausing to take a deep breath, she pinched the bridge of her nose. Crossing her arms over her chest, Sunset tried to think of an easy way to resolve this. She currently wore her favorite black leather jacket along with a light blue-green shirt and an older looking pair of jeans that had a few holes worn through them in various places.
"Fine, then how about this." She began, letting out a frustrated sigh. "We can just let him decide."
"Him? You mean Spike?" Twilight asked.
"Yea, why don't we see who he thinks deserves his special attention tonight," Sunset said, turning towards the purple and green dog in question. Twilight said nothing, only turning to look at Spike.
"Uhh..." He said, mouth hanging open. He honestly wasn't sure who to pick. He really didn't like the idea of having to pick a favorite.
Granted, Twilight had raised him since he was only a little pup, but at the same time, that felt unfair to Sunset. Both were equally good 'in bed', though in different ways. It was true that Sunset did lose her chance yesterday but he was also pretty curious to find out what Twilight apparently wanted to try with him.
As he thought about this, Spike noticed the way the two were looking at him. Sunset had squatted down to his level, her arms folded underneath her breasts in an effort to make her cleavage stand out to him a bit more. At the same time, the saucy gaze she was giving him was one that most guys would probably melt like putty under. Twilight, on the other hand, had gone for a slightly different approach.
She was down on her hands and knees right next to Sunset and had somehow managed to loop one of Spike's collars around her neck while he wasn't paying attention. One of his leashes was being held out towards him as she blushed with an adorkably nervous smile. While she didn't have the same kind of curves as Sunset, she easily made up for it in other ways.
But rather than win him over, both their efforts only succeeded in making him feel even more conflicted. Oh, how he wished that he could just choose both of them, but that solution hadn't worked out very well in the past. Despite now being a fully grown dog, he was still a pretty small breed. That, combined with his pretty lengthy 'recharge' time, got irritating for whoever was forced to wait their turn. He would have to find some other way to settle this...
'What if I gave them some sort of challenge or competition?' He wondered
He thought hard, trying to think of something they could do. He didn't want to make it too hard for one of them over the other, but at the same time, he didn't have much to go on for reference. Having been a non-magical dog for most of his life hadn't provided him with much material. Though, now that he thought about it, there was one thing that he used to do with other dogs at the city park.
He and a few of the other male dogs would sometimes compete with one another in a rather...unique way to entertain themselves. They would each try to find the riskiest or strangest places to do their business, all while avoiding the keen eyes of their owners or anyone else that might not want them leaving little presents behind. To his knowledge, humans didn't do that sort of thing, preferring to instead keep their bathroom habits mostly to themselves. That meant it would be very unlikely that either of them would be at all practiced for it.
'This is perfect! Neither of them will have an advantage over the other!' He thought excitedly. Plus, as an added bonus, he'd never been able to see a female dog playing the game before. Just the idea of Twilight or Sunset doing it excited him...
"Alright, I think I know just how we can settle this!" Spike declared confidently.
"You do?" Twilight asked curiously.
"Yep, with a little contest!" Spike replied.
"...What kind of contest?" Sunset said cautiously, noticing a slight edge to Spike's voice.
"Well, there was this little game that me and the other dogs at the park used to play together..."
"I cannot believe we're actually going through with this," Twilight said, nervously looking around at the inside of Sunset's apartment. She seemed to be trying to do anything but make eye contact with the girl standing next to her.
"I can't believe that Im desperate enough to be okay with us doing this in my apartment," Sunset added. "Spike, are you absolutely sure there isn't some other way?"
"Nope, It's either this or nothing at all," Spike stated firmly. He was sitting on Sunset's couch in the middle of the apartment, leaning up over one arm of the couch.
Much to Twilight's relief, they'd decided to move Spike's little competition to Sunset's place. Twilight's parents had recently called, notifying her that they'd be coming home much earlier than expected from their vacation trip to Las Pegasus. Given how messy the afternoon was likely going to get, Twilight probably wouldn't have had time to clean up before they arrived tomorrow morning.
"Well, um, I guess we should get this...competition started," Twilight said, reaching into her pocket and taking out a small bottle filled with dark-purple pills. "I, um, had these stored in a box in my lab, so I grabbed them on our way out. They should help to...move things along."
Sunset eyed the bottle cautiously. "What are they?" She asked, taking one from Twilight as she poured two of them into her hand. She held it up to look at in the light.
"They're a special kind of laxative that I'd been developing while I was still enrolled at Crystal Prep. I-it was just a silly idea I had one day...but they should speed up our body's waste production without causing any dehydration like a lot of modern-day medicines." Twilight explained, pushing her glasses up the bridge of her nose.
"Huh, why were you even making these laxatives anyway?" Sunset inquired, giving Twilight an eyebrow-raised look.
"L-like I said, it was just a silly idea I had one day. I abandoned the p-project after I left Crystal Prep." Twilight quickly blustered, her face heating up. Sunset had a feeling there was more to it than that, but chose not to prod the issue any further.
"Oookay...there aren't any weird side effects right?" Sunset asked. "I don't want this to end up a frozen block of ice like I did with that cold medicine you loaned me three months ago."
'I still can't believe Pinkie just happened to have that person-sized microwave just lying around in her backyard. I mean, Im glad she had one, but at the same time, why did she have it?!' Sunset thought, giving the purple pill a doubtful look.
"There shouldn't be any..." Twilight said though she didn't sound completely sure herself.
Sunset spared a glance back at Spike who was still watching them, his tail sticking straight up in the air and waggling back and forth with excitement. Just looking at him reminded Sunset of the heat that was still burning between her legs, waiting to be clenched. All she had to do was win this strange contest of his and he would be all hers...
A few minutes later found the trio sitting together on the couch, watching TV. Though, only Spike was actually paying any attention to what was going on on-screen as he sat between the two girls. Sunset and Twilight, on the other hand, were clearly feeling on edge.
After heading into the kitchen for a couple glasses of water, they'd both downed one of Twilight's laxative pills at the same time. According to her, it'd likely take around thirty minutes before the effects started manifesting. So here they were, about forty minutes later, and neither of them had felt a single thing yet.
During this extra time, Sunset had reviewed the rules of Spike's strange competition. It was three in the afternoon and until the effects of the pills wore off, whenever either of them felt an urge to use the bathroom, they were tasked with finding an unorthodox place to relieve themselves. Then, afterward, Spike was apparently going to be judging who'd done the best. Exactly how something like that was judged, she wasn't sure.
However, there were two special rules. The first being that neither Twilight nor Sunset would be allowed to enter the bathroom for any reason. The second was that they also wouldn't be allowed to relieve themselves in the same location twice. At first, Sunset was hesitant to think they would even be able to go more than once, but according to Twilight, the pills they had taken would make sure they would.
'Just how much are these pill supposed to make me go anyway?' Sunset thought, starting to regret agreeing to this...
*Urrglch*
Both Sunset and Twilight jumped at the same time as both their stomachs began making strange gurgling and groaning sounds. The two looked up at each other nervously.
"...I...I think that means the pills are starting to work- Ough!" Twilight suddenly gasped loudly.
"Twilight?! Are you alright-"
"I-i have to go!" She abruptly shouted, shooting up from the couch and instinctively bolting towards the bathroom.
She seemed to be tuning out Sunset's calls completely in her sudden desperation. Twilight fumbled and shook the doorknob of the bathroom, only to then remember that it had been locked. She looked around desperately as she clutched her tightening stomach with one arm, searching for anything that she could use as an emergency toilet.
The first thing she was able to focus on was a large flower vase sitting on a table in the far corner of the apartment. Too desperate to consider anything else, she went for it.
*Spllffplart!*
But then, as Twilight took her first step, she was stopped again as a very wet sounding shart forced itself through her anus, very nearly allowing the muddy avalanche building behind it to break free. Thoughts of preserving her dignity vanishing rapidly as her stomach started to seize and cramp, Twilight quickly hooked her thumbs around the hem of her jeans. With one swift movement, she yanked them down around her ankles and squatted down right in front of the bathroom door. She'd just barely gotten the hem of her now slightly muddied panties past her anus before the dam finally broke.
*Splorpft!*
A mushy, mostly liquid, torrent of poop burst from her quivering hole, impacting onto the hardwood floor with a surprising amount of force. Twilight's breaths were ragged and shakey as more and more of her semi-solid waste poured out of her like a hose. The seemingly endless contents of her bowels continued to pile up higher and higher beneath her rear, the mess slowly starting to spread out over the floor.
She gasped sharply as a particularly thick and solid turd stopped up the flow of diarrhea for a few moments as it attempted to wedge itself through her tight anus. But after another cramp, it finally popped free before falling down atop the growing pile. Twilight's anus felt like it was on fire and the shit passing through it seemed like hot lava. All Twilight was able to concentrate on was the loud splattering sounds coming from behind her as she very messily voided her bowels all over the floor.
It was only once the burning sensation in her rectum had finally begun to fade, a full minute later, that Twilight re-opened her eyes. Her whole body shook from the sheer volume of shit that she'd just expelled. Fearfully looking down between her legs, the miniature mountain of poop piled up on the floor beneath her had nearly reached all the way up to her ass. But despite not quite making contact with the brown pile, her rear had most certainly not gone unharmed. The area between and around her asscrack was heavily smeared and caked with shit, her twitching anus only standing out from it all as it remained slightly agape.
Suddenly, Twilight remembered that she wasnt the only one in the room. Face heating up intensely from embarrassment and shame, she looked back to the couch behind her. Spike was watching attentively, his front legs standing up on the arm of the couch. His tongue hung out the right side of his mouth and his tail was waggling side-to-side, faster than Twilight had ever seen it move before. More noticeable to Twilight, however, was the bright red 'spike' standing full mast underneath his stomach. It seemed to twitch and throb as she found herself hungrily eyeing its length.
Tearing her eyes away from it, she looked up to find that Sunset was also staring. Twilight thought she'd be disgusted, but her expression seemed to portray curiosity and...was that arousal? But as soon as she realizing that Twilight was looking back at her, she immediately turned the other way, her face turning as red as her hair.
Though Twilight was still wincing from the after-burn on her anus, she couldn't help but feel immensely relieved. It felt like she'd just been cleaned out after being constipated for weeks. Slowly standing up from her squatting position, she shivered as she felt her cheeks meeting and rubbing caked-on filth up against one another. Taking another look at the messy pile between her legs, Twilight couldn't help but feel a tiny bit proud of herself. She couldn't remember ever producing quite this much poop at once ever before.
'At least the pills seem to have worked correctly...'
Sunset Shimmer was doing her level best to look anywhere else but back towards Twilight as she had begun to clean herself up on the other side of the room. They'd set aside a few spare rolls of toilet paper from the bathroom for this very purpose, though Sunset wasn't so sure that they would even have enough. If what had just happened to Twilight was any indication, things were going to get even messier very soon.
But that wasn't the focus of her thoughts at the moment. Her stomach was still making the same strange grumbling and gurgling sounds as they had been before, though, for some reason, she had yet to feel any sudden need or urge to go like Twilight.
'I guess I have been feeling a little bit stuffed up lately...maybe that has something to do with it?' She wondered.
"Ah!" She suddenly heard Twilight gasp.
Looking over the back of the couch, Sunset was surprised to see Twilight now across the room from where she'd been before, holding the large flower vase that Rarity had given Sunset a few months back. The flowers in it had long since died though as, it turned out she wasn't all that good at keeping plants alive.
The reason for Twilight gasp became apparent as, while she was still bottomless, she was visibly about to lose control again. She was hunched over slightly, her mostly still messy behind spread to expose her widening anus. A large turd was visibly poking out and she seemed to be struggling to keep it in.
Twilight quickly flipped the vase upside down, dumping the dried flowers onto the floor. She set it on the floor before crouching down and placing her ass right on the opening.
"Hnngg-Ahh!" She grunted loudly, letting loose.
Noisy sounds of diarrhea followed as she started to fill the vase with shit. Diarrhea didn't last long, however, as next, multiple long snake-like logs slithered out of her. Looking up to Twilight's face, Sunset expected to find her looking utterly disgusted or ashamed with what she was doing, but it couldn't have been more towards the opposite. She looked like she had found heaven itself. She was smiling while giving the occasional gasp, though they didn't sound like gasps of pain or discomfort.
Then, to Sunset's shock and embarrassment, she reached a hand down and pressed her fingers to her pussy and began slowly rubbing the area. Instantly she started to moan loudly as the seemingly infinite amount of poop inside her filled the vase. This only appeared to excite her further as she accelerated her motions, openly masturbating.
'W-what was in those pills?!' Sunset thought, trying to comprehend how that much poop could possibly fit inside such a relatively thin girl like Twilight.
Unable to make herself look away from the spectacle, Sunset failed to realize that her own hand was slowly slipping down towards her crotch. It had been about to slip down into her jeans when she cringed. Her stomach was rumbling again, but the feeling was much more intense this time.
"Ung" She grunted, just now noticing a slowly growing tightness in her lower gut. Getting up off the couch, she began to look around for a place to go before things got too urgent. But where would be best if she wanted to win this thing? Spike appeared to still be completely focused on Twilight at the moment, humping the back of the couch as he watched his owner.
'I could go in the kitchen sink, that's pretty strange, right?' Sunset thought.
Then again, after Spike had made it clear that he didn't want either of them using an actual toilet, Sunset had a feeling Spike wouldn't be all that impressed with her just using the kitchen sink as one. Sure, it would probably be troublesome to clean up later, but it didn't really feel all that different. Based on his reactions to Twilight, he wanted something messy...
'I'm pretty sure Rainbow pissed in the sink one time at her own house when she got really drunk at one of Pinkie Pie's parties.'
At that, Sunset suddenly thought of what she was going to do.
She smirked. 'Spike didn't say anything about having clothes on did he...'
At the sound of Sunset grunting, Spike turned to see what she was up to. He was pleasantly surprised to see her starting to pull down her worn pants while still standing right in front of the couch. After a few moments, she wore nothing but a simple pair of white cotton panties and her light-blue shirt, with her jeans resting around her ankles. Sunset then bent down in front of the couch, hanging her ass over the cushion that she'd just been sitting on. On the other side of the couch, Spike watched excitedly as he realized what she was planning on doing.
"How's this for 'unorthodox', Spike?" She said between grunts.
Pushing as hard as she could, Sunset felt something huge press hard up against the inside of her sphincter. With another grunt, she felt her anus expand as it attempted to make room for a surprisingly solid brown log. She was stretched wider and wider as the heavy mass slowly emerged, spreading her more than she'd ever been before.
"Urgt!" She winced. "S-so much for those pills being l-laxatives," Sunset grumbled under her breath.
Spike was watching excitedly as her panties suddenly began to develop a tiny bump in the fabric which slowly but surely started to grow in size and length. As the solid log continued to slither out from between her cheeks, it smeared them with streaks of brown. The fabric of Sunset's panties stretched and contorted as they attempted to accommodate for the huge turd being pushed into them.
At one point, a much thicker section of the log was a struggle to push through, causing the now grapefruit-sized bulge to stop growing. But after another pained grunt from Sunset, she finally was able to keep the train going as she resumed pooping her panties.
As the log bent and coiled over itself beneath her rear, it grew very heavy in her underwear, causing them to hang down a couple inches beneath her. Finally, with one last push, the tapering tail end of her enormous log finally slipped free from her filthy anus, falling to join the rest of her load.
*Pfffwwwpapartpt!*
"Ahh~" Sunset sighed happily as let out a warm and airy fart that had been trapped behind the blockage.
Sunset panted quietly as her arms went limp from the exertion. Looking back over her shoulder, she was unsure what to even think about what she'd just done. As much as she felt that she should be feeling embarrassed and ashamed of the naughty taboo thing she'd just done, she found that she was feeling a bit..turned on. Biting her lip, she slowly shook her hips from side to side, the heavy bulge swinging along with her.
Spike certainly appeared to have enjoyed the show. A long string of pre-cum was dripping down from the tip of his canine cock, pooling onto the cushion he was standing on. Sunsets wished he'd just pounce her right then and there and push his dick right through her messy panties and into her ass. But as she let her messy rear sway from side to side, seemingly in an attempt to hypnotize the horny dog, she couldn't help but feel a little bit disappointed by the noticeable lack of relief she usually felt after pooping that much.
*Pwwwwft*
'Huh?' Sunset thought, hearing another fart. Looking down she realized it had been Spike who seemed to be sharing her 'enthusiasm'. Raising his leg, he let out another sharp fart. Sunset laughed and gave him a sultry look.
"You joining in or something?" She said.
Suddenly, Sunset gasped loudly as her stomach growled aggressively, an immense pressure making itself known in her rectum out of nowhere. She had absolutely no time to react as, just as Twilight's had before, her tired anus gave way to a flood of semi-solid mush. It spilled out of her like a river, instantly flooding what little room was left inside her panties and staining right through the fabric, turning it a dark and wet brown.
With nowhere left to go, the mess gushed out through the stretched leg holes of her underwear, oozing quickly down the back of Sunset's trembling legs and falling in globs down onto the couch with a series of wet *Plops*.
'Was that massive log holding all this back?!' Sunset thought.
Some of the flow managed to dislodge a portion of her previous mess, causing it to fall out of her panties and join the rest of the liquidy mess that had started building up on the couch beneath her. But despite the mess that she was making on her couch and the burning pain in her rear, Sunset couldn't care less as she was flooded with the immense feelings of release and relief that she'd been missing before.
"W-why does this feel sooo good?!" She moaned out to no one in particular.
With one last "Eep!" of pleasure, the contents of her bowels seemed to finally run dry. After taking a moment to recover, Sunset looked back again to asses the damage done. In addition to the near watermelon sized bulge in her panties, she'd left a large pile of shit, not dissimilar to Twilight's, on the couch. The back of her legs was caked with shit that ran all the way down.
"Woah..." She heard Twilight say.
Looking up, Sunset found Twilight was watching from right behind the couch, evidently having got up to come to watch. She had a shocked expression on her face and appeared to not register or not care that she was still bottomless, the top of her slender glistening slit visible from the front. After a moment she seemed to realize what she was doing and blushed madly.
"H-here, I think you're going to need these more than m-me..." She said, holding out the package of toilet paper rolls she'd been using earlier before the 'second wave' had hit. Looking past Twilight, Sunset noticed that the entire vase she'd been sitting on was filled to the brim with shit.
"Hmm, nah, Im good." Sunset eventually replied, finally standing up straight. Her ruined panties slid down slightly as she did so, exposing the top of her filthy crack in the process. She had to quickly reach down and hold up her panties in order to prevent them from falling to the floor.
"What do you mean?" Twilight asked.
Instead of answering, Sunset replied by simply leaning back and then promptly falling onto the couch butt-first. With a heavy *Splurt!*, the messy pile on the couch and her bulging panties met. The contents of her underwear smushed and squished against her ass, spreading even further and even seeping up towards her vagina. However, with a content and satisfied sigh, Sunset seemed unbothered. To her, It felt like she was sitting on a warm and mushy pillow.
"Ahhh~ Wow, that feels even better than I expected." She sighed, twisting her hips and causing even more of her load to ooze out through the leg holes of her panties. "Sorry Twi, but I think I got this competition in the bag." She said confidently, swinging one of her legs up and over the other. "Good luck topping this."
Twilight just stood there, stunned. The sound of Spike's rapid panting brought both of their attention downwards where the dog in question had started humping the mess surrounding Sunset's butt. He appeared to be in a trance as he quite literally fucked the pile of shit on the couch.
"Heh, I wish you'd had us do this ages ago, Spike. If I'd know not using an actual toilet could feel this good, I'd probably have been doing it ages ago." Sunset said though Spike didn't seem to really be paying attention.
Twilight bit the inside of her cheek nervously. As disgusting as all of this was, Sunset was right about it feeling pretty good. Reaching back, she felt between her cheeks. She'd done the best she could to wipe herself clean, but her recent mess now caked her rear.
"Well, S-spike still has to judge, and the effects of the pill might not be over yet!" Twilight argued defiantly.
Sunset raised an eyebrow and looked down at Spike who had changed places and was now humping the side of her butt, thrusting his filthy canine cock through the exposed leg hole of her panties. He seemed completely focused on what he was doing, acting more like a horny canine in heat than a magical talking dog.
*Fptpwwarpt* Another quick bout of flatulence ripped from Spike, acting as his cue to quicken his thrusts.
"I think he already made his choice. Sorry Twilight, I think he's too far gone to do any judging at this point." Sunset chuckled.
"B-but..." Twilight started to say. She seemed immensely disappointed.
'Well, I guess she didn't really have time react the first time like I did...' Sunset considered. She suddenly remembered the bottle of pills Twilight likely still had stored away in her hoodie.
"Hmm, well alright, how about this..."

Author's Note
Warning! As per requester's...request, this second chapter contains slightly more intense content than the first. This primarily includes: Piss Drinking, A Dirty Rimjob, And generally two girls getting pretty damn filthy together .
Getting Even Messier
"B-but, what if instead I-"
"Nope, that's the only way I'll allow it," Sunset affirmed, cutting of Twilight. "Either you do this or Spike is all mine for the rest of the night."
She crossed her arms over her, now completely bare, chest, however, they quickly shot back down in order to prevent her still loaded panties from falling down. Said thoroughly ruined undergarments remained the only article of clothing she still had on. Twilight, on the other hand, was completely nude.
The two stood just before a small and somewhat dusty screen door. It lead out onto a tiny balcony which hung over the sidewalk in front of Sunset's apartment. She never really found a good use for it before, but now it provided the perfect opportunity to have Twilight do something she'd always wanted to see, with a new twist.
At Sunset's feet, Spike was still humping away at her left leg, smearing her ankle with brown streaks as his cock was still coated with shit. He seemed to have gone in auto-pilot mode, in his own little lust-driven world.
"F-fine! I'll do it." Twilight grimaced, giving in. Her mind positively raced with the many ways that what she was about to do could go horribly wrong.
She bit her lip as she stepped up the door. It was getting pretty late now, but people could easily still be wandering through the streets. With an audible gulp, Twilight slowly pushed the open the door. A gust of cool evening air blew right through her, making Twilight's whole body shiver. Folding her arms over her breasts in a protective fashion, she took a tentative step outside.
The cold of the concrete balcony's floor shot up her leg, causing her to yelp and recoil. What if the very moment she went outside, a bunch of people noticed her standing up here, completely naked with her lower half smeared with mostly-dried poop.
Really considering the risks, Twilight turned around, intent on telling Sunset she was simply asking too much. But then she glanced down at Spike again. She found herself staring longingly at his messy canine cock, reminding her of why she so badly had wanted to have him tonight. Before tonight, the layer of poop which coated his cock's length would have likely disgusted her, but now it only boosted her desires.
After taking one last deep breath, Twilight turned back and stepped fully out onto the balcony. She quickly scanned her surroundings, checking up and down the sidewalks that ran from left to right only a floor beneath her and across the street. To her immense relief, there didn't appear to be anyone around. But she knew that, should someone happen by, they could easily spot her up here.
Not wanting to remain outside any longer than necessary, Twilight dashed to the edge of the balcony before taking one last glance back inside. Sunset stood in the doorway, giving her an encouraging nod.
Turing back, Twilight leaned forwards against the balcony railing and began spreading her legs apart, slowly inching her feet away from each other while bending over as much as she could. Her arms were braced up against the railing, pushing up underneath her breasts as they did so. At the same time, behind her, Sunset bit her lip as she admired Twilight's messy asshole.
"Hng!" Twilight grunted.
She felt a familiar feeling as her anus widened, her exhausted sphincter provided no resistance. Like a smelly brown snake, a thick log slithered down as It slid out from between her cheeks. Twilight had to admit it felt pretty nice doing something so naughty in the open like this.
Still feeling pretty on edge, a police siren from a few streets over startled Twilight, making her instinctively clench. She pinched off her log and it fell to the ground with a *Plop*. Looking back over her shoulder, she found Sunset still standing there, one of her hands moving rapidly inside her panties while the other held them up.
With another grunt, Twilight continued pooping, adding more to the pile on the concrete. She still wondered where all of this poop was even coming from. As the rest of her first log coiled around the first half, a bubbly wet fart following it out. Her anus was left gaping, the cool air sending shocks of pleasure through her.
But just as Twilight had begun sliding a hand down towards her dripping pussy, she heard something that made her freeze. Footsteps. Quickly looking to the left, she spotted two people walking down the sidewalk, about to pass right underneath her. But the worst part was that it was none other than her brother and his girlfriend. Twilight dared not move as the two grew nearer and nearer, fearing that any movement might cause them to look up.
All the while she remained helpless to stop another long and thick log of shit from pushing out of her asshole. Every little crinkle or hiss of gas that came with it made Twilight jump. Shining and Cadence would be so close now. Little did they know, she was taking a massive shit right in front of them.
'Please don't see me, please don't see me!' Twilight begged, her eyes clenched shut.
Twilight could feel her bowels growing lighter, signaling the end of her log. Shining and Cadence were about to pass right underneath her, having not noticed a thing. She was going to get away with it!
But then, just as the two were passing underneath her, an enormous wet fart splattered out, sending small brown chunks everywhere. The sound seemed to echo through the street, impossible to miss.
"Hey, did you hear that?" Cadence's voice said.
With a yelp, Twilight jumped up and lept back inside, falling over Sunset in her urgency.
Outside, the unsuspecting couple glanced up at the source of the strange sound they'd just heard, only to see an empty balcony above them, its door wide open.
"Someone's probably just playing an instrument or something," Shining guessed, shrugging his shoulders.
*Sniff, Sniff*
"Ooo, Cadence, is that you im smelling?" Shining asked, raising an eyebrow suggestively.
"What? No! You know I refuse to do that when we're out in public." She whispered sharply, blushing ferociously.
"Oh come on, you know you'd love it." Shining teased.
"Shhh, don't talk so loud! Someone might hear you!" She shushed.
"Ah, nobody is gonna hear us, this side of town is practically deserted this time of night."
"Just behave and take me home." She said, before looking around to make sure that they were alone. "If we don't hurry, I might not make it this time..." She teased back with a nervous smile.
It was Shining's turn to blush, an eager smile spreading across his face.
'The scenic route it is.'
"Mnf, Mf, Mmf!" Twilight moaned, rocking back and forth while one her hands and knees.
Her ass was high in the air and a dog collar had been tightly fastened around her neck. The attached leash would give her the occasional firm tug. Spike's front paws were pressing down on top of Twilight's head as he humped her face, plunging his cock down her throat with each of his beastial thrusts. Twilight relished every moment as it's many bumps slid over her tongue. Despite having recently being cleaned off, a slightly bitter tang accompanied its usual salty taste. It was something different, and Twilight knew full well what it was from, but Twilight absolutely loved it.
Behind her, Sunset gripped her ass with one hand, while the other kept the leash taut. Repeated wet slaps joined Twilight's muffled moans as Sunset thrust all six inches of her strap-on's girthy shaft deep into her friend's messy asshole. Biting her bottom lip, she watched the once bright purple dildo, now dyed a muddy brown, disappeared and reappeared in and out of her bowels. Sunset still wore the same pair of thoroughly ruined panties underneath, though some poop had been added to the load since. Not all of it was from herself.
The straps of her strap-on had been fed under and around the massive bulge, constricting and pushing the warm mess up against her. Her thrusting had already squeezed multiple formless mushy chunks of poop out through the stretched leg holes, joining the numerous messy piles that had already been scattered across Sunset's bedsheets.
"Nnf! Ha-having fun down there Twilight?" Sunset grunted, a shiver running down her back as she felt the mess in her panties brush her vulva.
The only response Twilight mustered came in the form of another grunt. Suddenly, Sunset felt something pushing against her. Looking down, she was pleasantly surprised to see another wave of shit oozing out from around the shaft.
"Heh, thought so. You're just love getting your filthy little ass pounded don't you?" Sunset teased, giving another little tug on Twilight's leash. She felt powerful, letting a bit of her old self shining to the surface.
She was also pretty surprised that the fabric of her panties was still holding after everything she'd done in them. It almost looked like she'd shoved an entire melon in them 'I'll have to buy more of whatever brand these ones are, especially since this is definitely not the last time we do this if I have anything to say about it.'
Entranced by the many future possibilities that bounced around in her head, Sunset barely noticed a new sensation prodding at her subconscious. Without any hesitation, and while still eagerly pounding Twilight, she relaxed and allowed a slightly different bodily fluid to flood her panties. A wet splattering alerted her to the forceful stream spraying the densely packed mess hanging less than an inch beneath her pussy. Her piss wasted no time in saturating whatever fabric it could reach, flowing down her legs and soaking into the bedsheets at her knees. The mattress was utterly ruined, but Sunset couldn't care less.
Then, Spike's breath suddenly started to quicken, as did his humping. Twilight, still in a daze, had little time to react as after one more thrust, Spike's swollen popped into her mouth. Despite his size, Spike's cock seemed to fill her mouth in its entirety, her tongue tickling sensitive areas as it throbbed hard. Ropes of thick cum burst from his tip, filling what room was left in Twilight's mouth and puffing out her cheeks. Before she could swallow it all some spurted out from around his shaft, dripping down her lips and chin.
Gulp after gulp, the flow of cum seemed never-ending. It was only once Twilight actually felt full that cum stopped oozing from Spike's tip. Spike appeared to be right about to start pulling out when he suddenly stopped, half of his length still in her mouth. Panting, Spike seemed to finally register the world around him. He would be kaput for at least thirty minutes but there was one last thing he wanted to do for Twilight.
While she had yet to actually say what she so adamantly wanted to try with him tonight, he had a pretty good idea he already knew. Even after how long it had been since he started to talk, Twilight would often forget he was anything more than a normal dog. There was a fair share of times he'd been in Twilight's bedroom when she masturbated, and often what she was watching on her computer was in full view.
Spike smirked and stepped forwards again, making sure his cock was deep in Twilight's mouth. Then, laying his head down on top of hers, he relaxed. Twilight let out a muffled gasp as a stream of pee shot from the tip of his cock, impacting the back of her throat. She gagged for a moment, though more out of surprise than disgust, before fully realizing what was happening. Once she did, her eyes went wide and she immediately began eagerly slurping down as much of the golden nectar as she could.
The salty taste was just as good or greater than Twilight had imagined. It seemed to act like some kind of aphrodisiac, making the pleasure she felt from getting her ass pounded even more mindnumbing. She felt an intense heat building within. Behind her, Sunset seemed to notice and picked up the pace, driving the entire shaft of her strap-on as deep as she could into Twilight. The thought of her stomach being so full of Spike's cum and piss was what finally drove her over the edge.
Though muffled slightly by the canine cock still in her mouth, Twilight's climactic howel rang out. Her entire body trembled and shook and her pussy quivered as jets of transparent juices shot out from it. The overwhelming combination of stimuli proved to be too much for her as her eyes rolled upwards and she suddenly went limp. With a wet *slick*, both Spike and Sunset pulled out, leaving Twilight laying passed out on the bed between them, a silly smile on her cum-stained face.
Sunset breaths were labored, not quite realizing how tiring all that thrusting had been until now. Spike, on the other hand, seemed completely satisfied, waggling his tail contently.
"W-whew..." Sunset sighed, looked down at the messy strap-on still protruding from her crotch. "Glad I finally got to use this thing, at least how it was meant to be used, heh." With Twilight out like a light, it was Sunset's turn to have some one-on-one time with Spike. Unfotruneltly, she'd likely have to wait for a while for him to 'recharge his batteries'.
*Pwwft*
Sunset thought at first the fart had come from Twilight but then realized it had actually originated from Spike. He seemed to have not even really noticed and was currently licking the drool and cum off Twilight's face.
"Hmm..." Sunset thought, getting an idea.
"You're sure about this Sunset?" Spike asked, sounding a bit uneasy.
"Yep, might as well try it after all the 'shit' I've done today," Sunset replied with a chuckle. She was laying down on the couch, now completely naked, with Spike standing on her chest. His front paws pushed down into her breasts, like two warm cushions. His little butt hung just in front of her face, and his tail was raised.
"It's just, I've never really- eep!" Spike started, only to be interrupted as he suddenly felt Sunset tongue graze up across his anus.
Sunset initially recoiled from the bitter taste she received, but pushed forwards anyway, giving the tight hole another lick. She circled around the edge of Spike's tiny anus, coating it with her saliva as she cleaned it. She felt Spike shudder, moaning silently. He was enjoying it more than he expected.
After her next few licks, Sunset felt Spike's anus start to quiver underneath her tongue. And then, just as she was preparing to dive back in again, she was met with a sudden gust of warm air as she was blasted with an airy fart. The unexpected nature of Spike's stinky surprise caused Sunset to briefly descend into a coughing fit, though she quickly recovered.
"Sorry! Are you alright back there?" Spike apologized, feeling bad about not warning her.
"Yea- *cough* -im fine, don't worry about it." She replied, sounding oddly pleased with what just happened.
Getting back to work, Sunset slid her tongue around and over every inch of the Spike's hole, yet even now she didn't feel satisfied. Reaching up with her arms, she took hold of Spike's rear, and using her thumbs, spread his anus apart. Spike yelped in surprise, the sensation strange yet pleasant.
With an apprehensive gulp, Sunset stared inside the dark hole. Closing her eyes, she dove forwards again, sticking her tongue in as deep as she could. Once inside, she felt around, tasting the same awful bitterness from before as her saliva mixed with Spike's anal juices. She swirled her tongue around and around inside him, making sure she got every inch. Then, a minute later, she felt Spike quiver again and readied herself for another powerful blast.
*Pffpwptt~*
A second fart, wettened slightly by her spit, sputtered out. Some gas managed to escape around her lips while the rest flooded her mouth. Despite this, Sunset held strong, never ceasing her actions despite the putrid taste. Spike moaned again, a bit louder this time. With him laying over her chest, Sunset could feel as his cock started to reemerge from its sheath, sliding down and becoming nestled between her pillowy breasts.
Spike was shaken from his brief stupor as he suddenly felt his stomach grumble. Sunset had felt it too, but unlike Spike, she failed to fully realize what it meant.
"Sunset, It's coming!" He quickly warned.
By the time the warning reached her ears, Sunset had reached her deepest inside Spike's butthole. At the same time, she felt the tip of her tongue make contact with something solid that hadn't been there just a moment before. The taste she received instantly made her pull back, very nearly gagging. But rather than move or push Spike off, she merely wiped her mouth and watched with a smirk as Spike's trembling anus started to widen. This was what she'd been hoping for. Ever since he started farting earlier, a dirty idea had popped into her head.
Spike grunted as his anus was spread apart. From within, the head of a solid turd peeked out, it's tip smeared with the barest hint of Sunset's spit. At this point, his canine shaft was rock hard and throbbed needily between Sunset's pillowy breasts as he found himself instinctively humping.
Sunset watched on, with one of her hands rapidly fingering her cunt as Spike's first log slithered down. It landed just beneath her neck, coiling over her upper chest. It felt warm and sticky and was quickly joined by yet another log which slipped effortlessly from Spike's well-lubricated anus. The pile eventually grew too large and collapsed, falling down over Sunset's neck.
Jamming three whole fingers deep into her still-messy pussy, Sunset found herself quickly approaching climax, the thought of being covered in her own, Twilight's, and now even Spike's shit finally driving her over the edge. Legs shaking, she came hard. Vaginal fluid burst forth, splashing down over the floor between her legs.
She eventually went limp, staring up at the ceiling in a hazy trance. Her whole body felt hot. Meanwhile, Spike had started aggressively humping, thrusting his cock back and forth between Sunset's breasts.
A few minutes went by before a shadow descended over the two of them. Sunset tilted her head up but was caught off guard as a stream of piss rained down over her face. It was Twilight, who wore a naughty grin as she stood next to the couch. Sunset didn't object though, opening her mouth and allowing piss to flow inside. She gulped down as much salty nectar as she could, relishing the taste of her friend's hot piss.
The next few minutes became something of a blur pleasure as they switched from position to position around the apartment. From Spike pounding Sunset' filthy ass while Twilight fingered her pussy, to Sunset giving Spike a blowjob while Twilight took her turn with the strap-on. It wasn't long before they both lost count of the number of times they'd each came. Their bodies were alight with pleasure almost constantly, waves of ecstasy that never seemed to end.
The next time Spike came again, he had returned to pushing his cock between Sunset's breasts, smearing them with his now shit coated cock. Ropes of cum were strewn across her toned stomach. Twilight, meanwhile was squatting down over Sunset's face, being eagerly eaten out eagerly as she cleaned Twilight's messy pussy. It was this final act that seemed to finally tire them out as they eventually collapsed on the floor, still covered in each other's juices and shit. Spike curled up next to the couch nearby, joining the others as they fell into a blissful sleep...
"I can't b-believe you talked *Ah~* me into doing this." Cadence panted, pinned against the inside of a phone booth.
"Ah, you know you're loving it~" Shining grunted, thrusting his hips forwards to plunge his thick shaft deep into Cadence's ass.
The two had been going at it for minutes now, the inside of the cramped phone booth getting hot. The walls of the phone booth they were in were covered almost completely by newspaper clippings and advertisements, allowing others to walk right past without even noticing a thing.
"I can feel *it*!" Shining panted, feeling the tip of his cock making contact with something hard deep inside Cadence.
The sensation drove him wild, his breath hitching as he quickened his pace, racing at record speeds towards his climax. Cadence felt a similar effect, as all her worries about being caught in here melted away. Her soaked pussy clenched, sending a shower of juices down between her legs. A small pool of fluid had gathered at their feet, slowly growing larger as more of Cadence's juices joined it.
She gasped as, just before she could cum, Shining Armor hilted his entire length inside her, dumping his load deep inside her already quite full bowels. The moment he pulled out, he continued stroking his shaft, coaxing out a few more spurts of cum. Cadence herself remained braced against the wall of the phone booth, and with Shining out of the way, was free to push out a different blockage.
Her gaping anus revealed a thoroughly cum-glazed turd. It slid down, bending towards the floor as it rapidly grew in length, before eventually snapping off and landing in the puddle between them. This managed to spur one last little spurt of cum from Shining, who promptly deposited it into Cadence's still-open anus. The two panted as they rode out their individual pleasure highs.
"H-how, the hell, are we going to clean all this up?" Cadence panted.
"We d-don't. Now come on, we need to go in case someone actually decides to use this thing for some reason." Shining said, collecting his pants from the top of the old and underused phone inside the booth.
Despite their disheveled state, the two were eventually able to get re-dressed and made their way swiftly back home. Her nerves still racing, Cadence squirmed, feeling cum and other dirty juices leaking out of her and collecting in her panties. Despite how scary it had been, Shining was right, they'd definitely be doing that again in the future...
