Twilight's pupils shrunk to pinpricks as she suddenly found out what Fluttershy meant. The scattered smirks and the fact that most of the stallions in the room were now staring directly at her crotch all but confirmed it. She was bottomless and completely exposed in front of a large crowd of ponies that she didn't even know.

Her hands immediately darted downwards, pushing her skirt back down and holding it there as blood rushed up to her cheeks. She cringed from the hot fire of embarrassment as a few whistles rang out amongst the crowd. Some of the mares seemed to sympathize with her plight, looking away with a blush out of respect or by smacking their coltfriend in the back of the head. Though, there were still a few mares who appeared to be staring just as much as the stallions.

"Oh um, darling!" The voice of a familiar unicorn called out from the far corner of the room. "I do believe you left these behind at my boutique earlier!" Rarity called, waving a pair of panties in the air in an effort to get her attention.

In an instant, Twilight vanished in a purple flash, reappearing a moment later right next to the fashionista. She swiped the panties out of Rarity's waving hand and hurried to put them back on. Looking around, she was thankful to see that most ponies were already losing interest and the crowd around the front door had already started to dissipate. Many went to get food and drinks from the various tables that had been set up around the room.

Rarity giggled as she saw Twilight's intense blush. "Oh, I'm sure after that little show you'll receive plenty of that attention you were wanting." She giggled before pausing to briefly scan Twilight again. "Hmm... perhaps the slutty schoolgirl outfit does work for you rather well after all, even if it is a bit out of style." Rarity pondered, swirling a half-full wine glass that was resting in her other hand.

The heat of embarrassment still burning brightly in her cheeks, Twilight turned to rebuke the fashionista, only for a bubbly pink blur to suddenly spring up between them.

"Hiya! I'm Pinkie Pie and I threw this super surprise party just for you! Were ya surprised?! Where ya?! Where ya?!"

"Y-you threw a surprise party in a library?!" Twilight growled, gritting her teeth.

"Yup, yup! It's perfect, right? I mean, nopony would ever expect a surprise party in a library!" Pinkie Pie exclaimed excitedly, bouncing around seemingly oblivious to Twilight's barely contained fury.

"Gah!" Twilight scoffed, turning and stomping away.

Following right behind her, Pinkie continued to babble away at speeds that were almost impossible to understand. Groaning, Twilight reached one of the tables and absentmindedly grabbed an empty red cup from a stack before pouring herself some red punch from an oddly butt-shaped bowl.

'Well, I'm never going to get anything done down here with all these crazy ponies around. Might as well just head upstairs and pray to Celestia they're not up there too.'

Tilting her head back, she lifted the cup to her muzzle. Behind her, the hyperactive mare was evidently trying to tell her something but Twilight just tuned her out, downing the punch in one aggravated swig.

'At least the punch tastes good...'

Back on the other side of the room, Rarity took another small sip from her own glass, watching Twilight as she stomped up the stairs. Meanwhile, the rather handsome looking drake from earlier was being blindfolded as a few ponies were setting up a game of 'Pin The Tail On The Pony'. Though, the particular picture being used did not match the normally foal-friendly game.

Dragons weren't exactly a common sight around here, and the few that had visited the town in the past had usually been attempting to burn it down or kidnap somepony. But since his arrival, word has spread pretty fast that a non-violent dragon was in town and an attractive one at that. She'd already heard about him long before they'd first met, but was pleased to see the rumors weren't exaggerated.

'I wonder if he'd be interested in modeling a few outfits for me. He would certainly be quite the frame to work off of, that's for sure...' Rarity pondered, taking another small sip as she watched him being spun around and around in preparation for the party game. He seemed to be enjoying himself quite a bit.

*Pwwwwft*

"Whoops, oh my." Rarity gasped as she felt a quick fart rip from her behind. "It seems Pinkie's special party punch is just as effective as usual~" Rarity giggled, a familiar tingling coming in her stomach. "I'll need to careful of how much of this I'm drinking, I don't want anything unfortunate to happen while in this new dress of mine... not here anyway..."

"Hey, um, Rarity?" A timid voice asked as Rarity felt a light tap on her shoulder.

"Hm? Oh, hello there Fluttershy, darling. How are you this evening?" Rarity greeted with a surprised smile.

"Oh, um, I'm okay," Fluttershy answered sheepishly, blushing whenever another pony even so much as looked in her general direction.

"Well, that's wonderful to hear. I really can't say I remember the last time you actually came to one of Pinkie's delightful parties."

"Yea um, say Rarity, I was wondering... Do you know what kind of clothes d-dragons like?" She asked, anxiously squirming where she stood as the words came out.

'Oh?~ What's this now?' Rarity thought, suddenly very intrigued in her friend's motive.

"Hmm, I can't say that I do, unfortunately, their kind isn't exactly known for their innovative fashion sense." She explained, much to Fluttershy's visible disappointment. "However, I'm sure if you were to swing by my boutique sometime tomorrow I could suggest a few things. What might be the occasion?" Rarity asked innocently, though she had a pretty good idea that she already knew the reason.

'Could it be that our new resident dragon has already ensnared dear Fluttershy's heart as well?'

"I-I was just... c-curious that's all." Fluttershy stammered, tilting her head down and hiding behind her mane.

Rarity decided not to push any further for now, though she was eager to see where this would go.

"Well anyway, have you tried some of Pinkie's special punch yet? It is positively divine~."

"Oh, um no, I don't really drink Pinkie's punch anymore. Don't you remember last time?"

"Oh Celestia, I can't believe I'd forgotten all about that little incident. After all, It took me weeks to get the stains out of that poor dress I made for you. Yes, I suppose it would probably be better if you didn't, especially in a library. The punch seems to be particularly potent today anyway. I've only had a few sips so far, but I'm already feeling the effects..."

Twilight let out a frustrated sigh as she stared out the window above the bed upstairs. The moon seemed to be staring right back at her as she fumed about her frustrations.

She'd hoped that coming upstairs would finally allow here some quiet time to herself, away from all the noise and commotion going on downstairs. But unfortunately, she'd only half succeeded. While she was at least alone now, she could still very clearly hear the rhythmic beats of the loud music pumping on the floor below.

'Ugh! Where in Equestria is that even coming from?! I didn't even see any speakers down there!'

With the party raging on, she would have a hard time focusing on getting any research or writing done. But regardless, she needed to get that report to the princess as soon as possible. Who knew when Nightmare Moon might return and try to take over Equestria!

As unlikely as it was, should the princess still not believe her even after sending a full report, Twilight still wanted to do some more research on the Elements Of Harmony mentioned in the book. If the legends were indeed accurate, they could be Equestria's only hope.

*Grumble*

Adding to her worries and frustrations, Twilight's stomach groaned loudly, an odd tingly feeling starting to flutter inside her belly. She was really starting to worry that something may have been done to the punch she'd drank...

Spike was leaning against a bookcase, drinking from a cup of water he'd just fetched from the kitchen. He was originally going to get some punch but then overheard from some stallions that something was up with it. He wasn't sure what exactly, but he'd rather be safe than sorry.

Overall though, he was having a pretty time so far. For the first time he could remember, he was in a new town wherein the inhabitants didn't all see him as some kind of barbaric brute or monster. Not only that, but he'd already met a number of hot mares and even managed to successfully pin the tail on the pony on his first try. He was particularly proud of that last achievement.

Still, Spike was feeling pretty bad for Twilight. He'd had a number of opportunities to let her know about the whole 'missing panties' situation but just got so distracted talking with Fluttershy that he'd completely forgotten. The guilt was really starting to get to him.

'I really should go find her and apologize. I just hope she doesn't get mad at me for not saying anything sooner...'

But just as he was about to start looking around for the purple unicorn amongst the crowd, Spike heard somepony call out to him.

"Yo, dragon boy! Over here!."

He looked over to see the rainbow-maned mare from earlier peeking out from behind the door that leads into the kitchen, beckoning him towards her with one of her wings.

'Huh, I wonder what she wants...' He thought, unsure about the stern expression on her face.

As Spike started to make his way over, she disappeared back into the kitchen, closing the door behind her. Upon reaching it, Spike opened it and curiously peered inside, only to find the kitchen completely dark. Thanks to his dragon eyesight, he could still see decently thanks to the dim light coming in through the open door but he didn't see Rainbow Dash anywhere.

'Huh? Where'd she go?' He pondered, taking a step in through the doorway.

Suddenly, a pair of blue hands reached down from above him and grabbed the collar of his shirt. He was tossed forward into the room as the door quickly slammed shut behind him. Spike turned around as the lights were flicked on next, revealing Rainbow Dash standing in front of the door, her arms crossed over her chest as she leveled an intense glare at him.

"Uh... is there something you need fro-"

"What's your game?!" She abruptly asked.

"What? What do you mean 'my game'?" He replied, wondering what he could have possibly done to make her so angry.

'Did I do something wrong? Shit, I sure hope not. These ponies were just starting to like me.'

"Don't play dumb! I know everything! Now tell me what did you do to Fluttershy!" She growled, wings splaying out in a threatening fashion.

"...Fluttershy?"

"Yea, lizard-brain, Fluttershy! I don't know what kind of freaky dragon magic you've cast on her but it ends right now!"

"W-what?! What are you talking about?!"

"I just got here for this party and what do I find? Fluttershy, of all ponies, chatting it up with a bunch of random stallions she's never even met! Now, I've known her since we were both fillies and she has never so much as approached a stallion she doesn't know!"

"Well, I don't see how that has anything to do with-" Spike tried to counter, but Rainbow kept going.

"And! When I go to ask her what the deal was, all she'd talk about was dragons this, and dragons that! Apparently, she'd gone to the stallions for advice." Rainbow fumed, seemingly ready to pounce him at any second. "So? Out with it! What kind of freaky spell have you put on her?! I bet that unicorn upstairs was one of your previous victims! Is she some kind of pony sex slave of yours or something?!"

"What?! No! I would never do anything like that to anypony! And I certainly don't have any 'freaky dragon magic'!"

She stared at him for a long time, glaring deep into his green lizard-like eyes while seemingly judging whether or not he was lying.

"Hmph, fine, but I'm watching you, lizard-breath! If I see you so much as lay a finger on Fluttershy, I'll beat those scales right off you! You got that?!" She threatened, flying right up into his face until her muzzle was pressed against his.

He nodded quickly, hands raised in surrender. She kept glaring distrustfully for a few more seconds before finally darting back out of the room with a few powerful flaps of her wings, flicking the lights off as she left. This left Spike standing alone and quite confused in the dark kitchen.

'What the hell was that all about?' He thought, shaking his head. 'Seems like I really can't go somewhere new without somepony yelling at me for just being a dragon...'

Still, she had at least mentioned Twilight's whereabouts. She'd apparently already gone upstairs, which wasn't entirely surprising. She'd want to get as far away from the noise and other ponies as fast as possible. Hopefully, she was doing okay after her embarrassing moment in the spotlight earlier...

*Pwffrrfprt*

"Ah~" Twilight sighed, leaning forward in her seat as she scanned through a few of the books that were kept on the second floor of the library.

So far she'd had zero luck in finding anything more about the Elements Of Harmony. Not a single book up here had anything even remotely related to the subject. Assuming this library contained anything about them at all, it was probably kept downstairs. At this point though, she refused to go back down there. Ever since drinking that punch, she'd been feeling extremely gassy.

*Pwrwfrfrpt*

"Ough. Wow, that smells." Twilight murmured waving a hand in front of her muzzle to dispell the stench that just ripped from her behind.

It smelled a bit like the pies she'd eaten earlier, just far less appetizing. She was surprised though that, even with all the gas she'd was having, she hadn't really felt any signs that she might need to use the bathroom too. All that food at the apple farm would have surely made its way through her system for the most part by now.

She, like most other mares, did of course suffer from a lack of sensitivity in her bladder and bowels, though It wasn't too extreme in her case. It usually varied in severity from pony to pony, but hers was just enough so that feeling a sudden urgent urge to go while out in public usually resulted in an accident unless she could find a bathroom fast.

This seemingly needless change in a mare's biology had always fascinated her, even before hitting eighteen herself. Yet, despite trying a number of different experiments over the years, even going so far as to write a report about the subject to the princess, there didn't appear to be any discernible rhyme or reason for the change. Or even what caused it.

It just seemed to... 'happen'. Though this drove her crazy for a while, eventually, like the rest of society before her, she'd come to just accept it and move on with her life. Still, even after all this time, she felt as if there was something inherently strange about the whole phenomenon.

"Hey, Twilight, are you up here?" She heard Spike's voice call as the door to the stairs creaked open. The sound of party music boomed behind him.

"Yea, I'm here," Twilight replied with a sigh.

As he entered, he quickly closed the door behind him, once again muffling the music. He looked a bit bothered by something as he made his way over.

"Not having fun at the party full of crazies?" She asked sarcastically.

"Oh no, well yea it's alright I guess, but I er... I just wanted to apologize." He explained, scratching the back of his head awkwardly as he pulled out the second chair under the desk and sat down.

"Apologize? Apologize for what?" She asked apprehensively, suddenly fearing the worst as she imagined the downstairs erupting into bright green flames.

"It's just, I feel like it's kinda my fault you got, uh, 'exposed' earlier. I should have... noticed and said something to you about it before you got embarrassed like that."

Twilight sighed, partly relieved that this was all he was anxious about.

"Don't worry about it Spike, it really wasn't your fault. I, of all ponies, should have noticed that I was missing my panties. Especially with how long we were outside."

"Yea but-"

*Prfrprprt*

A wet sounding fart suddenly cut him off, making Twilight groan and hold her stomach.

"Are you feeling alright Twilight?" Spike asked, concerned.

"Yea, I'm fine. A-anyway, what were you saying?" She said, grimacing as her stomach churned.

"I... nevermind, it was nothing."

"Well alright. By the way, you didn't drink any of that punch downstairs did you?" She asked.

"No, I just got some water from the kitchen. I heard some ponies saying that there was something up with it."

"Great, I thought so."

"Why? Did you drink some of it?"

"An entire cup full, yea, and ever since I've been feeling super gassy. It's probably nothing serious, just some stupid party prank like the kind Minuette pulls sometimes."

"You want me to go down and ask if anypony knows anything?" Spike offered.

"No, it's fine, I'll just-"

*Pflrrrptrtrrtpt*

"-wait it out. Say, could you bring up our suitcases for me, please?" She asked. "There might be a party going on, but I really need to get that report done, no matter what it takes."

"Sure thing Twilight, I'll be right back." He replied, getting up and heading for the door.

As it closed behind him, Twilight couldn't help but think back to each time he'd been admiring the mares they'd met today.

"Why can't he ever look at me like that?" She mumbled without thinking, only for her to realize what she'd just said a moment later.

"Woah! Where did that come from?!" She said, surprised that she could even think something like that about someone who was basically her little brother. Thankfully, another brief buildup of pressure in her rectum distracted her.

*Pwwfrptrrpt*

'Whew, that one felt wetter than the others... maybe I should head to the bathroom, just in case. I only have a few pairs of panties packed for this trip anyway. I can't afford to let them all get dirty.' She thought.

As Twilight got up out of her chair, she could feel a few tiny wet splotches that were already splattered on the inside of her underwear. Thankfully, there was a bathroom up here, in addition to one downstairs. It seemed like a bit much compared to the average house, but right now she was just glad that she didn't have to go downstairs to use one.

Twilight was about halfway across the room when she felt yet another ball of gas demanding an exit from her clenched anus. Contemplating it for a moment, she shrugged and bent over slightly to let it pass.

'What's a little more gas at this point anyways~.'

*Pwwwwft-Pflorpt!*

Twilight gasped in surprise as the fart she had been expecting was instead revealed to be a massive surge of diarrhea. Brown sludge quickly spewed out into panties, flooding them in seconds as more liquidy mess poured out of her. In mere moments it stained right through the soft white fabric, turning it a wet brown color.

Twilight was left breathless as waves of relief washed over her while she pooped her panties, her feast at the apple farm finally catching up to her. Both the leg holes of her panties were pulled down as the weight inside them grew. Twilight remained bent over, hands on her knees as she was left stunned at the suddenness of what was occurring. But then, just as fast as it started, it was suddenly over. Her bowels felt empty again and her panties were filled to the brim with mushy shit.

Once she was able to collect herself, she reached a hand back and felt the squishy wet bulge in her thoroughly ruined panties. The muck reached up through her crack, partially exposed from how much her underwear was sagging. Meanwhile, more of it had seeped forwards, threatening to coat her marehood in filth if she had done anymore in them.

She was surprised that the fabric had been able to hold everything inside without letting any of it escape down the insides of her legs. This was easily her messiest accident in a long time too.

Turning to make sure Spike wasn't back yet, Twilight hesitated before pressing her hand into the center of the bulge, biting her bottom lip as she felt the warm mush inside squish up against her cheeks. Removing her hand, she sighed in disappointment and wiped the sticky brown smears on her fingers off on one of the remaining unstained parts of her panties. Unfortunately, she wouldn't have any time to enjoy her accident, especially with Spike about to return at any moment. Not to mention, she still had to get some work done on her report.

'I'll just have to wait for Spike to get back and hope that he remembers to bring both suitcases with him. My only other two pairs of panties are inside one of them and I'll need them before I can go to the celebration later.'

She prayed there was a shower in the bathroom on the upper floor. Twilight had a feeling that she wouldn't be able to get away with just wiping a little bit this time...

*Pflorp*

A small chunk of poop had just slipped out of her panties following another short fart, landing on the floor between her feet.

'Great...'
