"Well, 3 PM, on the hour. Are you sure this is the right place, Sonic? It's not really like Tails to send out invitations so secretly like this; don't you find it just a bit suspicious???" Sonic, Knuckles, and Amy, who'd been out and about partaking in their usual daily activities, had gathered on this particular afternoon to meet with Tails, who'd evidently sent each of them a private invitation to one of his more remote workshops to 'show them something they needed to see to believe'. The trio of friends had been instructed on their invitations to meet up at what looked like a shady, run-down facility that hadn't been upkept in years. 

After arriving at the entrance to the institution, Knuckles and Amy began getting tense over the off-putting aesthetic the building exhibited. Sonic worked to dispel their skepticism, trusting that his sidekick wouldn't lead them into potential harm or danger. "Don't sweat it, Knuckles! Tails wouldn't direct us to a place like this if there were anything to worry about, you know that!"

"Yeah, well, that's kinda what I'm afraid of, Sonic. How do you know these invitations really were sent by Tails, and it's not just some ploy by Eggman to lure us all into one place?" Knuckles rebelled nervously. Amy's fear began to get the better of her as well. 

"Knuckles is right, Sonic... if this is some plot to take us by surprise, then Eggman must have us right where he wants us! Don't you think you're being a little too relaxed about this? I mean, look at the place! It looks like the roof could cave in any second!!!" Just before Sonic could offer a word of reassurance, the door to the workshop swung open. A bright and eager-looking Tails gleamed with excitement at the others, gesturing for them to enter his rather quaint abode. 

"Thanks for coming, you guys!!! I know this might seem a little strange, bringing you all to such an unusual location so abruptly, but I promise there's a good reason for that! I've been working day-and-night for weeks on these ideas that were brought up to me by the VP of a prestigious corporate firm. It started out as just a commission to fulfill their request, but I kind of got a little carried away, heheh..." Tails scratched his head and turned, leading his friends deeper into the workshop. "And let's just say, after many sleepless nights here, I think I've finally got something I can present to them! In fact, I think it's something so special, we might even be able to change the world with it! So naturally, who better to unveil my latest inventions to than my three best friends in the entire world!?" It was obvious by his tone that Tails was dying to reveal what exactly he'd been putting so much time and effort into.

"A prestigious corporate firm?" Sonic asked, sounding intrigued and proud of his friend, "wow, this must really be something, Tails! I'm excited to see what you've had cookin' up in the lab!" 

"Me too!" Amy chimed in, "I'm so proud you're getting noticed as an inventor, Tails! I'm sure you made something great." 

"For weeks?" Knuckles asked, "sounds like a huge deal!" "Oh yeah, trust me," Tails said, sounding more and more excited as he led his friends further in, "this is gonna change the way you think about everything." The two-tailed fox finally reached his working desk, where all sorts of papers and lab materials were sprawled out. Sitting on the center of the desk was what looked like a very small energy bar, about the size of a stick of gum. "This," Tails said, picking up the tiny packaged bar and holding it out in front of his friends, "is what I've been working so hard on." Sonic, Amy and Knuckles appeared to be very confused by what they were seeing. Was Tails just working on...a protein bar? For all this time?

"Uhh..ummm...it looks great, Tails!" Sonic said, trying his best to sound interested and encouraging.

"Oh--don't worry about how it looks, I'm still designing the packaging," Tails said as he smiled nervously and scratched the back of his head. 

"Wh-what is it?" Amy couldn't help herself from asking, just as confused as her friends were. 

"Yeah, what does it do? Is it just an energy bar or something?" Knuckles asked the fox. 

"Not quite, but close," Tails said, unwrapping the bar and holding it up to his friends. "This right here contains all the nutrients a Mobian needs for an entire day. If you eat one of these babies in the morning, you're set for a full 24 hours before you feel hungry again." 

"R-Really?" Sonic said, truly amazed by what he was seeing. "This is amazing!"

"Yeah, imagine how many hunger problems this would solve!" Amy said, happy that Tails achieved what he set out to do and that his idea had some amazing real-world application. 

"Hold on..." Knuckles said, sounding a bit confused, "how does this thing work?"

"I thought you might ask that," Tails said, unwrapping the bar fully, "first, the user eats the bar." Tails popped the tiny unwrapped bar into his mouth, chewing and swallowing what he ate. 

"After that, as long as the user steadily drinks water throughout the day, the bar will remain in the stomach and expand, keeping the user full and providing a steady flow of food to the small intestine, where the nutrients can be absorbed for the body to use. 

"Wow!" Sonic said, "are they easy to make?" 

"Yeah! I simplified the recipe so that they could be cheap to produce," Tails said, his face beaming after seeing his friend's eager approval, "and I get to present it to the investors tomorrow!" Tails's stomach grumbled in front of his friends, making him blush a bit from how audible it was. 

"Haha, sounds like it's working," Knuckles said, smiling at Tails as he laughed to himself. 

"Yep, heheh," Tails said, "feels like it, too!"

A question floated through Sonic's mind after hearing his friend's stomach gurgle as loudly as it had. "How'd you manage to test these things out, anyway? Couldn't it be dangerous if you eat one and they don't do what you want them to do?" 

"Err, well, funny you should mention that, heh..." Tails blushed a bit as he began to explain. "The testing phase itself wasn't particularly troublesome. First, I worked to mathematically derive a formula that I could use to approximate how large the bars would ultimately expand, given contact with an indefinite supply of water, just to ensure they wouldn't be able to expand ad-infinitum. To do this, I aggregated several values of porosity from random locations on a sample bar, which allowed me to figure out how much water one energy bar could physically soak up before reaching its largest mass. Then..."

Tails looked up and was met with the perplexed facial expressions of his friends, indicating that he'd lost them somewhere along in his explanation. "Um, a-anyway... The point is, the math backs it up! After I did that though, I performed some external tests. Because the energy bars react to water, I was able to drop some sample bars into the pond behind the workshop and observe how they reacted. Some expanded to a dangerous degree, while others didn't expand at all! I repeated this process and made the appropriate adjustments until they began to expand to an ideal size. Once I could repeat this reliably, I knew that the bars had been a success! As for the nutrients and such, it's my own special recipe. Don't worry though! It's all organic, I promise!" The other three watched on as Tails deeply explained every step behind the creation of the energy bars. Eventually, Knuckles interrupted Tails' passionate explanation after noticing a very small box occupying one of the corners of the workshop.

"Hey, Tails, I don't mean to cut you off, but what's that thing in the corner over there?" Tails turned his head, then blushed a bit as he smiled back at his friends. 

"Eh-heheh... ah, yeah, that. Well, Knuckles, there's a small side effect about the energy bars I may have failed to mention before..." The three each raised a brow, suspicious of what Tails hadn't gotten around to telling them yet. "See, the energy bars themselves weren't what I had been commissioned by that firm to develop. That was just an afterthought. Apparently, the board of directors had urged an executive at the company to contact me about an idea he had. He explained to me that a politician friend of his told him that Mobius has been facing an increasingly hazardous problem with the underground pipe systems, and that reliable plumbing may not be an option for all Mobians in a decade or two from now. He wanted me to design a product that could work around the issue of plumbing altogether, at least to some capacity." 

"...aaaaaand...?" Knuckles began growing impatient at Tails' extensive monologue.

"Well, that box in the corner over there is actually the contraption that the firm wanted me to invent for them. They figured that if they could make a significant profit by fixing the plumbing epidemic before it even became an issue because of my invention, that they might consider sharing with me some of their own private assets that I've been dying to see for myself!" The workshop went silent for a moment as the fox's friends digested his explanation. 

"So, what you're saying is, you invented some mystery device that'll solve a major local crisis, and then just for fun, you also created a superfood that could put an end to hunger altogether?" Amy reiterated. 

"That's... so... AWESOME!" Knuckles shouted, clearly very proud of his ingenuitive, two-tailed pal. 

"Yeah, that brain of yours is really something special, Tails!" Sonic praised. Tails blushed even harder upon hearing the slew of compliments. 

"Aww, you guys..." The fox's stomach groaned loudly again, embarrassing him even further as his friends giggled at his noisy belly.

"So, then, what's the box supposed to be, exactly?" Knuckles asked again with a burning curiosity. 

"Heh... well, I'll show you guys," Tails grabbed the box and put it on the floor in front of him, "...but you have to stand back!" He urged the three back several steps, leaving a bit of open space on all sides of the box. He pressed a button that was on top of the box. It made a beeping sound, then began to expand in all directions. Once it finished taking shape, Tails looked to his friends to gauge their reactions. 

"...is that..." Amy trailed. 

"...a toilet?" Knuckles finished her question. 

"Heh... yeah... you remember the unintended side effect the energy bars cause that I mentioned earlier? Well, all that food's gotta go somewhere eventually!"

"Well, I suppose that's right," Amy said, showing a bit of disgust as Tails's words painted an unflattering image in her head.

 "So this huge thing just folds out from that little box?" Knuckles asked, sounding intrigued. 

"Uh huh, that's right! It was quite the challenge to put together, what with the laws of physics and everything putting up roadblock after roadblock, but I eventually came up with this design!" Tails said, proudly gazing upon what he created. 

"What kind of a toilet is it?" Amy asked, showing confusion as she tried to figure out it's strange design. "I've never seen one that looks like this before." 

"That's because this right here is a Japanese style squat toilet!" Tails proudly stated, watching as his friends continued to gaze in awe. "Typical western toilets make it difficult for your, ahem, 'waste' to properly exit the body, but this particular design allows for the puborectalis muscle to fully relax, allowing for a full, uninhibited flow of...said waste. After that, specialized lasers that I installed in the toilet will vaporize what was...produced, leaving no evidence that the toilet was even used!" 

"Wow! It's great, but..." Sonic said, eyeing the design for a moment but noticing a potential flaw after looking at it for long enough. 

"B-but what?" Tails asked as his expression changed to one of worry, concerned that he overlooked a crucial flaw in the design. 

"It's just...is there a way to make it more...private?" Sonic asked, hoping he wasn't ruining Tails's presentation. "The back of the toilet is left completely open, and if I were using this..."

"Oh!" Tails interjected, feeling a bit relieved, "I left that part out intentionally to be able to present the device to the investors. Speaking of which, That's another reason why I invited you all here today. Would any of you be interested in helping me present the things I've made to the company? I don't think I can do it without an assistant, and it would be a huge help for me!" 

"You need an assistant?" Knuckles asked, sounding excited about the idea of helping the fox out. 

"I'll do it, Tails!" Sonic said, cutting Knuckles off and stepping forward, "I kinda owe you for always backing me up on our adventures." 

"Really, Sonic? You'll do it?" Tails said with eagerness in his voice, sounding excited. "I really appreciate this, Sonic! It means the world to me that you're willing to do this." 

"Sure thing, pal!" Sonic said, smiling down to the two-tailed fox, "I'm always happy to support you and your cool inventions." 

"You guys better start preparing soon!" Amy advised both the hedgehog and the fox, "you don't want any embarrassing mistakes in front of the company heads, do you?" 

"I guess not, huh?" Sonic said, looking over to Tails. "Tails, how should we prepare for this? Is there a script or something we need to memorize?" Tails remained silent after Sonic asked his question, pretending to be thinking to himself as he tried his best not to blush. He had neglected mentioning to Sonic that the company scientists wanted to see both the 'results' produced by the sustenance bar and the toilet working to get rid of those 'results'.

"Uh..." Tails began, unsure what to say to his friend, "how about we just discuss it tomorrow morning?" 

"Are you sure you don't wanna get this presentation ready tonight? You worked so hard on this, and..." Sonic said, only to be interrupted by Tails who was worried he'd have to reveal to Sonic in that moment what he'd need him to do in the demonstration. 

"Umm...don't worry about it, Sonic!" Tails said as his face continued to grow redder. "I'll handle all the planning. I just need you to show up here at 8:00am tomorrow morning and we'll go over everything." 

"Alright, Tails," Sonic said with a confused expression as he scratched the quills on the back of his head, "whatever you say, I guess." Sonic, Amy and Knuckles began to walk out before Tails remembered one last thing he needed the blue hedgehog to do. 

"Wait!!!" Tails shouted, causing the three to turn back to the fox. 

"What is it, Tails?" Amy asked, wondering what the fox had forgotten about. 

"I just remembered, Sonic," Tails said, extending one of his bars to him, "I need you to eat this."

"One of your bars?" Sonic asked, walking up and taking it from Tails's paw. "I guess it would be cool to try one..." Sonic took the bar an unwrapped it, popping the whole thing in his mouth and chewing before swallowing it all. "Hmm..." he said, thinking to himself for a moment and letting the taste resonate, "I kinda like the flavor!" 

"It'll fill you up, too!" Tails said, holding a paw over his belly, "the one I ate sure filled me up, haha!" 

"Eight o'clock tomorrow morning, right?" Sonic confirmed as he began to walk out. 

"Yep!" Tails said as he waved Sonic off, "thanks again so much for doing this."

The day continued on as normal with everyone resuming their usual activities. Tails spent the rest of the evening in his workshop, double-checking and triple-checking that everything was in tip-top condition for tomorrow morning. He made slight adjustments to the Port-o-Box, as he dubbed it, which kept him plenty busy through the following hours. His mind was kept so busy, in-fact, that he didn't even pause between work sessions to eat, drink, or--ironically enough--use the bathroom. As he gradually felt the bar continually digest and supply his body with energy, he at one point considered performing an early test with the Port-o-Box, just to make sure it worked as it should. However, he ultimately trusted that his intricate plans and calculations had been executed and measured flawlessly, and decided to leave it be for Sonic's "demonstration" tomorrow.

Finally, night fell, and after many more hours of restless labor, so did Tails' eyelids. 

"Yawwwwwn... Well, I've finally made every modification I can think of... this should be perfect for the presentation. I'd better get plenty of sleep for tomorrow..." Grooooooannn...
Unfortunately, Tails had been so focused on attuning his inventions to absolute perfection, that he had failed to notice how frequently his stomach had been rumbling the entire evening, warning him that he should have probably taken a moment to make use of his own device. "Eheheh... maybe just oooone test of the Port-o-Box before bed wouldn't be so bad. I mean, I could always chalk it up to experimental testing in the name of science!" 
…….. 
"...but then again, I'm starting to feel reeeeally sleepy, and that bed looks reeeeally comfortable right now..." Tails walked over to the bed before glancing once more at his new prized technological innovation. "Yeah, I shouldn't dirty it up just yet. I really want Sonic to get the most out of it when he shows everyone how it works tomorrow. I'll just wait until after the presentation!" With that, Tails buried himself in the bed's blankets, and fell asleep almost as soon as his head hit his pillow. Finally, a good night's sleep... he thought.

All throughout the night, Tails found himself tossing and turning in his sleep. It wasn't anything discomforting enough to wake him from his slumber, but little did he know, he'd begun farting up a storm as he rested. 

Brrrrt, Frrpt! Braaaap... 

At one point during the night, much to the fox's unaware misfortune, things began getting more backed up than he'd anticipated, as he eventually cut one fart that pushed something a little more concerning with it. 

fffff-- Tails unconsciously stiffened his body as his anus was met with the tip of a heavy log--the first mass of waste of many that would begin trying to force his tailhole open. A soft crackling could be heard as while Tails slept, the head of the log poked his butthole open, becoming exposed to the open air. Tails grunted softly as his anus began opening, little by little. 

Just as it was about to open wide and begin releasing the enormous log, however, the fox suddenly tossed in his sleep, contracting his anal sphincter and forcing the log back into its tight, ever-filling chamber. 

Brrrrrt... An hour later, and Tails finally awoke as the sun beamed through the workshop's dusty, worn old window. The first thing he noticed was how much more drastically full he felt than when he had put things to a halt the night before.

"Woah," Tails said to himself, holding a paw over his belly as he sat up in his bed, "I've really gotta go, heheh." The two-tailed fox could feel how much fuller his large intestine and rectum were since he had gone to sleep the night before, and realized that he'd probably need to use the bathroom soon. "What time was the presentation today gonna be again?" Tails asked himself softly, soon remembering the time that the executives had given him. "Oh yeah! It was 11:00 in the morning, wasn't it?" The fox looked over to the clock he had on his bedside table, hoping he would have enough time to find a place to use the bathroom before he'd need to leave for the presentation. "Let's see...the company's headquarters is about 2 hours away by plane," Tails thought to himself, "so I'll need to leave at 8:30am just to be safe. And right now, it's...8:00!" Tails smiled and exhaled a sigh of relief. "That gives me just enough time do my thing and be able to leave in time!" 

KNOCK KNOCK KNOCK 

"What the--? Oh no, I totally forgot!" Tails said, hearing the knock on his lab door and remembering that he was supposed to go over the presentation with Sonic this morning. "Uhh--coming!!!" Tails walked over to the door with both of his tails down, feeling too backed up to fly right over as he usually did. The young fox pulled the front door to the lab open, gretting the blue hedgehog standing in the doorway. "Hey, Sonic!" Tails said with slightly bent knees and a barely-noticeable agitated expression.

"Hey Tails," Sonic replied, noticing that something was a bit off about Tails. "You doing alright buddy? Are you nervous about the presentation?" 

"Th-The presentation?" Tails said, glad Sonic wasn't questioning him about what was really wrong. "Oh, uh--yeah, just some pre-performance jitters, heheh!" 

"Well, don't worry," Sonic said reassuringly as he stepped into Tails's lab, "you're gonna do great today! It'll be a total piece of cake."

"Heheh, thanks, Sonic," Tails sheepishly showed his friend his gratitude. "Your confidence will definitely help in this presentation." 

"What's there to not be confident about?" Sonic encouraged his friend, "your inventions are amazing! Speaking of which, let's take a look at them real quick and run through what this presentation is gonna be like." 

"Yeah, heheh...right..." Tails replied nervously, blushing as he thought to himself about how in the world he was going to tell Sonic what he actually needed him to do in the presentation. The two Mobians made their way over to where Tails was keeping both inventions. Picking up a bar off of the table, Sonic couldn't help but turn to Tails and praise him on his work. 

"I gotta tell ya, Tails," Sonic said, holding the bar up to the fox, "this thing really filled me up!" 

"Oh really?!" Tails said, sounding excited as he received confirmation that his recipe was likely to work on all species. "That's great news." 

"And, uh..." Sonic continued, beginning to blush as he glanced over to the Port-o-Box Tails had built and had set up in the center of the room, "you weren't kidding about how much they make you need to..."

"Heheh, yeah," Tails blushed, scratching the back of his head. "I guess that's the one drawback to a bar like this: all the food you need but at the price of all the waste that comes along with it." 

"Speaking of that..." Sonic said, unable to stop himself from blushing as he tried to explain what his situation was. "Do you think it'd be okay if I gave that toilet of yours a little...'test drive'?" 

"Uhh...ummm, well," Tails stuttered, still unsure of how to break the news to Sonic but fully aware he'd have to let him know one way or another. "The thing is...I'm gonna need you to hold it until the presentation." 

"Until the..." Sonic began to reply, suddenly getting a bad feeling in the pit of his stomach. 

"The...the scientists and investors who are watching my presentation want to..." Tails started to explain, almost too embarrassed for Sonic to continue. "They want to observe the toilet being used by a Mobian who's consumed one of the bars..."

"...is that why you didn't run me through what we'd actually be doing during the presentation until now?" Sonic's excited tone had all but disappeared. 

"Ehm, w-well, kinda..." Tails was afraid Sonic might suddenly decide to back out. After a moment of silence, Sonic finally spoke back up. 

"Geez, Tails, you really have to keep me informed about this stuff!" Sonic's smile and enthused expression returned. Phew. Glad he seems okay with the idea...Tails thought. "I definitely don't mind giving it a try in front of the big wigs up there, but I would have appreciated if you'd told me sooner, buddy!" Sonic patted Tails on the back as he said this. 

"A-ha, sorry Sonic, I didn't mean to keep you in the dark, I was just afraid that--" GrRrRrRrrrrrgle...

"--ooh... S-sorry Sonic, the energy bar I had yesterday kinda put me in the same boat as you, heh..." Tails suddenly remembered the discomfort he'd have to endure during the presentation, and hoped it'd be a quick one, for his own sake. 

"Yikes, sounds like that portable bathroom of yours is going to get a good test run after all!" Sonic teased. Tails blushed as he knew Sonic was aware of exactly what his intestinal distress implied. 

"Hehe... as badly as I need to use it myself, I think I'll just hold off until after we present. I kind of want to be a surprise for you the first time you see it in action!" Sonic's expression suddenly grew serious again as he just remembered something. "Hey, uh, Tails?" 

"Yeah, Sonic?" Tails replied.

"I don't mean to throw a wrench into things, but I just remembered that my body's kinda bathroom shy sometimes. These guys won't actually be able to see me doing, eh, y'know... right...?"

Tails' intuition suddenly turned dark, like he knew something bad was going to happen soon. "Well, umm, actually Sonic, they... kinda will? I know it's going to be weird and everything, but--"

"Oh," Sonic interjected, "I guess it's all right. I'll certainly try to use it when the time comes then, but there's a small chance I maaay freeze up and not be able to actually go. If that happens, do you have a backup plan?" The fox's two tails suddenly raised on their own accord: 

Brrp! 

"A-ah! Sorry...!" Tails wanted to apologize profusely for passing gas in front of his longtime best friend. 

"Hey, don't sweat it buddy!" Sonic tried to reassure his friend, "Remember, I'm feeling the same way as you right now! As a matter of fact, maybe even a little worse. Be thankful you didn't stay the night with me last night, I'll just put it that way. But having said that, just in case I can't get myself to actually do my business in that thing, you should be able to demonstrate it yourself, right? I mean, it sure sounds like there's no shortage of, well, you get my point." 

"Oh, oh yeah! I don't see any reason why I wouldn't be able to show them how it works myself, I suppose. I'm just... extremely shy about that stuff, kinda like you. But, they are specifically asking to see us go firsthand, so just in case you can't do it when the time comes, I'll go ahead and show 'em myself!" 

KNOCK KNOCK!

"Huh?" The two looked at each other in confusion. Tails walked over to the front door and opened it. 

"Surprise!" Amy exclaimed as she hugged Tails, who could see Knuckles just behind her, grinning with eagerness. 

"We came to watch your presentation, Tails!" Knuckles explained, "We figured that if this is going to be something that could change Mobius entirely, we'd want to be the first to see it happen! And, uh, provide moral support, of course." Both Sonic and Tails felt waves of horror wash over them realizing that their friends would be there to watch them 'use' the Port-o-Box close-up. You've gotta be kidding me! There's no way I can use that thing in front of Knuckles and Amy! It was going to be hard enough trying to use it just with Tails and the execs watching! Sonic's mind raced in a profuse panic.

"Uh...are you sure you wanna come see the presentation?" Sonic asked, trying his best to get his friends disinterested. "It's pretty boring stuff. Just a bunch of big sciencey words and nerd things." 

"Sonic!" Amy exclaimed angrily, glaring unhappily at the blue hedgehog, "Tails worked very hard on his inventions; we don't think it's boring at all! The least we could do is tag along and show our support!" 

"No no, trust me Amy, Sonic's right," Tails interjected, trying to steer the conversation in the direction Sonic had intended. "You and Knuckles don't wanna go to this boring thing. It'll probably make me too nervous to present if you come along!" 

"Haha, you don't have to worry about being nervous in front of us, buddy! We're here to make you feel better about this thing!" Knuckles said, walking up to Tails and giving him a slap on the back. Unfortunately for the fox, the slap on the back he just received caused a gas bubble he was holding back to escape. 

FFRFT! 

Tails's face turned bright red as he slapped his paws over his rear, smiling nervously to his friends. "Heh, sorry about that," Tails said, trying to hide his embarrassment. "I think you guys are already making me anxious," Tails said, looking over to Sonic in the hope that the hedgehog would back him up. 

"Y-Yeah!" Sonic said, looking to Amy and Knuckles, "you both should probably stay back here. We'll let you know how the presentation went! C'mon, Tails, let's get going!" Sonic picked up the compact port-o-box from the ground as he looked over to see Tails grabbing some papers and his prototype sustenance bar from his desk. "Right with you, Sonic!" Tails said, starting to make his way out of the lab with Sonic. Unfortunately, they only got as far as the front door to the lab, where Amy was waiting with Knuckles, standing with her arms crossed. 

"That's total nonsense, Sonic!" Amy said, looking angrily at the blue blur.

"Yeah! A little pre-presentation gas is...normal," Knuckles offered from behind Amy, noticing Tails acting a bit more embarrassed after he heard his remark. 

"We're coming with you to show you our support, whether you like it or not!" Amy affirmed, making Tails and Sonic's stomachs sink as an embarrassing image came into their heads about what kind of presentation they'd have to end up watching. "I was even thinking of inviting some more of my friends to see you present! Cream was saying she'd love to come see you and your new invention." 

"Nononono!" Tails said, smiling nervously after realizing he was probably confusing Amy with his eager discouragement. "You both can come along, just...don't invite anyone else, alright?" 

"Uh...Tails?" Sonic said, pointing to a clock on the wall that read '8:40', "I think we were supposed to leave ten minutes ago." 

"Gah!" Tails said, checking one more time to make sure he had everything he needed. "C'mon, everyone! We're heading to the plane!" The group of four exited the lab, with Sonic and Tails in the lead about ten or so feet ahead of Amy and Knuckles.

"Why do you think they're so nervous about us coming to this presentation?" Amy whispered to Knuckles, wondering what could've been the cause of their jumpiness. 

"Psh, they probably realized they didn't have enough time to rehearse the presentation and now they're gonna bomb," Knuckles said, laughing a bit before being glared at by Amy. "Hey, it's still a great idea, and I'm sure Tails will be able to do a good job showing it off. I'm just saying that this presentation might be a little rough around the edges is all." Ahead of Knuckles and Amy, Sonic and Tails were beginning to panic about the presentation they were going to give in front of their friends. 

"Tails, this is not what I signed up for," Sonic whispered to the fox as they approached the plane. "I don't know if I'll be able to do my business in front of them," the hedgehog said as he let a silent fart hiss out, "hnngh, even when I have to go this bad."

Tails' trusty handmade plane, the Tornado, was sitting just behind the workshop. The team of 4 walked over to it and paused. Amy was the first to mention the plane's apparent lack of available seating.

"Hey, Tails? Doesn't this thing seem a bit small for the four of us? How are we all supposed to fit when it looks like only 2 people can squeeze into the cockpit?" 

"A good question; luckily, I prepared for something like this months ago. Check this out!" Tails opened one of the doors to the plane and powered it up. Its propellers began whirring rapidly, producing a loud buzz as they rotated in place. The fox hopped into the cockpit, and pressed a blue button on the control panel. Suddenly, the latter half of the plane began to move. Pieces of metal and other components were translated about, transforming the plane into a longer, sleeker ride with an additional seat fit for 2. 

"Wow! That's the coolest thing I've seen all day!" Knuckles impressively declared. As Knuckles and Amy began boarding the back seat of the Tornado, Sonic used the excess noise it produced to discreetly release some more flatulence. It was fairly audible, but fortunately the noise coming from the plane masked it well enough that nobody noticed. Finally, Sonic proceeded to hop in the front seat with Tails. 

"Is everyone buckled in?" The blue hedgehog performed a quick safety check with everyone. 

"Yep!" "Yeah!" "Of course!" After ensuring everyone was prepared for takeoff, Tails began rolling the plane across the perimeter of flat land behind the workshop before it finally ascended into the blue skies above.

Eventually, they touched back down about 5 minutes away from the corporate headquarters they were supposed to present at. Tails checked the time on his plane's dashboard as they landed. "10:55!? Guys, we need to g-get over there now!!!"

Sonic, Amy, Tails and Knuckles all hopped out of the plane, with Sonic and Tails making sure they had everything they needed for the presentation. 

"Phew," Sonic said to himself as he hopped out, noticing his urge to go had grown over the two hour flight. "These bars sure do the trick, don't they..." The whole group started running over to where the company's headquarters was, with Tails choosing to run on the ground with his friends in order to keep the load building up in his rear all held in. Running when I'm this full is kinda tough, Tails thought to himself as he let some silent gas loose on his run over, hoping they were all running too fast to smell anything. After running for about four minutes through the grassy plains they landed on, the group eventually reached the road leading straight to the tall building ahead of them. 

"Quickly, we're almost there!" Tails said, continuing to run with his friends until they all eventually made it to the building's entrance. 

"Hey...Tails?" Sonic whispered to the fox as he stepped up next to him, trying to stay out of earshot of Knuckles and Amy. "Are you sure you can't let me test out that toilet thingy real quick? I'm kind of about to b--"

"--Mr. Miles Prower?" The voice of a secretary rabbit stepping out the front door of the building interrupted Sonic, drawing the attention towards Tails and herself. "You're a minute late. The board doesn't have all day to wait for you, you know..." 

"Sorry, sorry!" Tails apologized profusely, bowing his head down in shame before looking back up and following the rabbit inside. The secretary led the group through the lobby of the building and into the elevator. 

"Wow, even the elevators are super nice!" Amy said, admiring the architecture around her. The rabbit pushed the button that would take them to the top floor, standing in silence as they began to ascend. Sonic and Tails were still both struggling to hold in the loads they had been carrying up to this point, and with the added anxiety of the presentation just around the corner, Tails was having trouble holding in his building gas. 

PFFFRRT! 

"Aw, gross, Tails! In the elevator?!" Knuckles complained, laughing and waving his paw past his nose. 

"S-Sorry," Tails said, keeping his tails down as he watched the secretary wince in disgust. "Still nervous, I guess, heheh..."

After what seemed like the longest elevator ride in history, they finally made it up to the boardroom on the top floor of the building. The secretary allowed the others to exit, before wafting the bad air out as the doors closed behind them. They were immediately greeted by a panel of fancy suits and other entrepreneurs of high social status, a couple whose faces they recognized on billboards and television commercials. The four looked to one another, then back at the table of executives, who stared back silently at the group of friends. Tails, figuring he was acting as the "head representative" of his own group, stepped up first.

"Eh, um, hello everyone! My name is Miles Prower, but I spoke to one of you over the phone not too long ago under the nickname 'Tails'. Are there any preliminary questions or comments before I begin the presentation?" Though he didn't say so aloud, Tails secretly hoped one of the executives would give him a quick rundown as to how the occasion would unfold, given such an experience was far out of his own element of comfort.

"Yes, Mr. Prower," One of the executives stood up and walked toward the fox, putting a hand out and formally introducing himself, "the one you spoke to over the phone before was me, Mr. Davis. It's a pleasure to make your acquaintance. My only question before we begin is, who is this group of individuals behind you? We hadn't discussed bringing others to this presentation during our phone-meeting." Tails suddenly realized the unspoken rule he'd probably just broken by letting his friends tag along without notifying the members of the boardroom prior. He quickly tried to improvise an excuse that would make it seem like their company was implied from the start. 

"Err, well, yes, the three you see behind me are some of my frie--uh, 'colleagues,' that aided me with miscellaneous things here and there as I developed this new technology. I do believe as we talked over the phone, that I briefly mentioned having us demonstrate this technology to you firsthand--something I wouldn't be able to do on my own, given I'm responsible for presenting and explaining the inner workings of it all." 

"Huh. I don't recall your mention of bringing along company, but I suppose I may have overlooked your statement at the time." It wasn't the best excuse, but the one who called himself Mr. Davis seemed satisfied enough with it. Tails felt a bit of relief as he continued: 

"Anyway, just to quickly clarify for everyone today, my colleagues and I are here to present to you a piece of technology that your firm had commissioned me to design for you, in exchange for private access to some valuable assets that we'll discuss in the coming days. So if there are no more questions, I guess we'll begin...!"

Tails walked over to the front of the boardroom with an energy bar in-hand. His confidence was thoroughly shaken as he stared across the room, his eyes being met with the glares of many important figureheads and icons--as well as his those of his closest friends. He'd left the Port-o-Box in Sonic's hands for when the time came for Sonic to demonstrate its functionality, as he wanted to first present his ingenious energy bars, that which he still hadn't come up with a name for. "First, before I show off that gadget over there," Tails pointed at the compact Port-o-Box Sonic was holding, "I'd like to briefly show you all a little something else I was inspired to develop. I'll be having one of my colleagues, Knuckles, demonstrate it for me!" He gestured to his friends for Knuckles to come up to the front of the room.

The echidna, confused, hesitantly walked over next to the fox. His nerves immediately began to overwhelm him as he found himself to be in the spotlight among some very famous names. "All right, everyone!" Tails held up the energy bar in one hand for everyone to see, "This right here is a little something I designed as I brainstormed ideas for ways to improve Mobians' hectic day-to-day lives. It may look like just a granola bar, but it's actually something quite special! Once ingested, it absorbs some of the water the user drinks throughout the day, and like a sponge, it expands not just from water-weight, but in its own mass as well! This provides vitamins and nutrients that would otherwise take several meals to attain, all in one sitting! Knuckles, if you wouldn't mind trying one yourself?" The fox looked expectantly at Knuckles, who'd suddenly realized just how unnerving it was being in front of a crowd. He regretted teasing Tails about his low expectations for the presentation behind his back.

"Uh...s-sure!" Knuckles exclaimed nervously, shakily taking the bar from Tails's hands. He unwrapped the small bar and popped the whole thing into his mouth, starting to chew. "Hmmm...tastes pretty good!" Knuckles commented between chews, trying to get more comfortable as he continued to stand with Tails in front of all of the executives. 

"Now, my friend Knuckles here is going to finish this bar pretty quickly, thanks to its convenient, compact size," Tails said to the executives, hoping to sell them on the bar's positive aspects. "At this point, all he'll need to do is drink water periodically throughout the day," Tails said, handing Knuckles a water bottle he had brought along with him, "and the bar will supply him with all the nutrients he needs, keeping him full for 24 hours!" 

"24 hours?! In that little bar?" Mr. Davis said, giving an impressed look to some of his colleagues as he wrote down his impressions on a notepad in front of him. 

"Heheh, that's right, sir!" Tails said proudly as he watched Knuckles drink the water he had given him. 

"W-Wow," Knuckles said, holding his paw over his stomach, "I can really feel myself filling up! H-How did you do this, Tails?" 

"Well, it's my own secret recipe!" Tails said, looking over to the investors, "that I may be willing to share if you're all willing to agree to the terms we set, heheh..." 

"This is all amazing, Mr. Prower," one of the bigwig mobians said, "but we're also interested in the other invention you brought over since your first one was so incredible. Could you tell us what it is before you have your friend bring it up? I'm just dying to know what it could be!"

"Ah, yes.." Tails said, his blush beginning to form as his mind transitioned over to the subject matter of his next invention. "This particular invention was the product of the plumbing crisis on Mobius that your team informed me of." Tails was going to continue speaking, but he felt a sudden shift in his bowels before he could get any words out. He was doing a good job holding in his load until then, but his urge had crept back up on him at the worst possible time. "Th-The device I brought to you all today i-is..." Tails started again, feeling a gas bubble poking at his exit before he ran out of strength and couldn't hold it back any longer, lifting his tails slightly as a reflex. 

FSSSSPFRT!  

What started as a silent hiss quickly grew into a more audible poot as Tails blushed a deep red from his embarrassing emission. 

"D-Did you just...?" one of the executives asked as he sat in disbelief of what had just happened. The nervous fox looked over to his friends, who he could tell were cringing in second-hand embarrassment from the volume and unfortunate timing of his release. 
"BAAhahahahaha!" Mr. Davis broke out into laughter, unable to contain himself from seeing a young little fox embarrass himself while he was giving a presentation. The rest of the executives joined in, some not wanting their colleague to be the only one laughing and some of the others genuinely finding it funny. Tails looked over and even saw his friends joining in on the laughter, making him blush even more. "Don't worry, Mr. Prower, I'm sure you're just a bit nervous," Mr. Davis said, "we do have business to get to, however, so please continue with your presentation." The room had settled back down and Tails had recomposed himself enough to keep going with what he was about to say. 

"Right. A-As I was saying, this new invention of mine is designed to vaporize any...ahem, 'waste' produced from eating the bars I made. Sonic, if you'd be so kind to bring up the device?"
Sonic had been dreading this moment since the presentation started. While the room was a bit lighthearted thanks to Mr. Davis's laughter, he still had to do something completely humiliating in front of a whole room of business mobians, making him blush bright red on his beige-furred cheeks. 

"You'll do great, don't worry!" Amy said to him, resting one of her paws on his shoulders and giving him a kind smile before he turned to the front of the room and approached Tails with the box. He turned to his audience and set the box down on the ground between himself and Tails. 

"Now, what could be better than a toilet that vaporizes any waste produced by the user?" Tails asked the room, pressing the button on top of the box and watching it unfold before them. "One that can fold up into a tiny box and be taken on the go, of course!" The toilet had now completely unfolded, revealing itself to be a squat toilet positioned to where the user's rear would be facing the executives. The room filled with applause from the board as the device revealed itself, making Tails smile as he received his praise. 

"Wow, this is amazing, Mr. Prower!" Mr. Davis said, applauding the fox. "You said you had a demonstration prepared for us as well?"

"A-heh, uhhh..." the executive's comment caught Tails off guard, realizing just what he was about to make his best friend do in front of an entire room of people. Sorry for this Sonic, but you did agree to it after all! He thought to himself. "O-oh yeah...! A demonstration! Sonic, if you'd be so kind?" He looked over to his hedgehog pal, who he expected to be getting into position, but Sonic had apparently been just as frightened by the idea as Tails. The two stood there, looking at one another like two deer staring into a set of headlights. 

"Um. Tails, I..." Sonic began. "I don't think I'm, uh... ready, for this demonstration...? I-err, I uh..." At this point, it was clear to Tails that Sonic was trying to go back on his word. C'mon Sonic, you're the one who volunteered to help!!! Tails was feeling the pressure get to him as he felt the patience in the room begin to dwindle away. And unfortunately, that pressure didn't just come in the form of tension. 

BRRRRRrrrllllt... 

A horribly rancid fart broke the silence and blew the fox's two tails into the air as he was fixing to succumb to his urge to defecate. "Oh, uh, yikes, Tails! Sounds like you're much more suited to demonstrate your invention than me, so I'll uh, let you do that then!" Sonic raced back to the other side of the room, rushing to escape both the permeating smell and any attention that had been put on him.

No no nonononono! Not now!!! Tails crossed his legs and tucked his tails between his own cheeks as a built-up heap of fox dung bulged his butthole outwards, nearly forcing it open even despite his resistance. He tried to think fast of a way to gracefully bring the presentation back on track. He realized the only way of doing so was right in front of him, and it was the one option he'd hoped he wouldn't have to resort to. Regrettably, he spoke... 

"...uh, t-thank you for doing your p-part, Sonic...! Now allow me to d-demonst--" brrrrphh "--nngh... Don't w-worry, this is just part of the--ungh--presentation... w-watch closely now, everyone! O-or don't..." Knuckles and Amy stared speechlessly, wide-eyed as they realized how Tails was about to 'demonstrate' his contraption's practicality. Sonic felt extremely relieved seeing that Tails was letting him off the hook for now. His own bowels felt only moments away from forcing Sonic into the same situation as his furry friend, though. He decided to sneak off seeing that everyone's eyes were on Tails, and took the elevator down to take care of his own business in private. Tails turned his back toward the crowd, and squatted into position, his rear hovering just over where he'd be 'depositing' his waste. Everyone stared as his swollen butthole twitched and puckered. 

Frrt, Blllrrt... Finally, Tails closed his eyes and tried to relax.

The embarrassed fox could feel a breeze over his exposed butthole as it began to open, welcoming the first of his logs to the open air. Trying to not whine in shame, Tails grunted as he began to push. "Hnnngh...hmph," Tails strained, hearing his first log begin to crackle and pop on it's way out, making all sorts of squishing noises as it did so. 

"Is he seriously..?" Tails could hear one of the investors closer to the front say, making him continue to blush. He could feel the air on his tight, furry ballsack as his log continued to descend from his exposed anus. 

"This is...quite the demonstration," he heard another executive say. The log continued to emerge before finally tapering off and plopping into the toilet underneath Tails's rear, making the fox sigh in relief.

"Hahhhh..." Tails sighed loudly as he basked in the glory of his first release, soon remembering he was still in front of a room of carefully watching business people, not to mention his close friends as well. Unable to stop himself from looking behind him to see if his friends were looking, Tails's worst fears were realized when he saw all eyes in the room on him and his exposed, dirty tailhole. 

PFFFFFRRRFT! 

Tails's expression turned into one of surprise after he unexpectedly released an enormous fart, feeling another log start to poke out from his twitching, pink anus. He was about to start pushing, but he suddenly heard something behind him that struck nothing but fear into him: laughter. It was somewhat soft, but some of the executives behind him were laughing at what was happening. Glancing back again, he saw that even Knuckles couldn't help but giggle at the humiliating display he was putting on. Tails was frozen by his embarrassment, unable to continue pushing without freezing up.

"Hey, don't worry, Mr. Prower!" Mr. Davis said from where he was sitting, having to stop himself from giggling, "just keep going! You're doing a fine job up there!" 

"Y-Yeah, Tails!" Knuckles chimed in, also holding back giggles. "You're doing great so far!" Tails turned his head back to face forward, away from the watchful eyes of the crowd behind him before trying to relax again. 

"Hnnnng," Tails grunted, feeling his next log begin to emerge in front of the whole room. As he was trying to clear his mind of all though while he did his business, Tails suddenly remembered that without an assistant, no one was talking about how the toilet works! "Uh...th-this toilet here is..." Tails said, straining to push out his second log as it slowly inched out with embarrassing noises to accompany it. "It's designed after J-Japanese squat toilets, allowing for an u-unnnhh..." Tails grunted loudly, continuing to push out his second log as it slowly descended from his rear and plopped next to his first log. "Uninhibited flow of waste." Tails could still feel quite a bit left in his rear after dropping his second log. "Geez, these bars make you produce so much..." Tails whispered to himself as he continued to burn red.

He felt another log press against the inside of his rectum, but figured he should take a moment to explain some things before continuing on with the show. "As you'll see when I'm done, the toilet will use some laser technology I drummed up in my lab to completely... v-vaporize the waste on c-command..." The furry fox struggled to get the last few words out as a third log had begun protruding from out behind him. He felt a lot of gas deep inside him pushing against the other end of the log, helping it come out faster than the others. They also began to get progressively softer and lighter in hue as they emerged. A muffled brap was heard as some gas escaped his buttcheeks between the puckered rim of his anus and the mass of waste, inciting further giggling from the executives and his friends. He heard one of the suits toward the back whisper: 

"At least this'll give us something to talk about at the soiree tonight." The fox whined quietly to himself as he understood just what a mistake it had all been putting the demonstration together the way he had. After the third log finally plummeted into the toilet's deposit area, which was now completely full, Tails was about to turn back around to show it in action vaporizing the waste, but quickly reconsidered as he thought about how he'd have to squat back down and resume doing his... business, in-between sessions, which he really didn't want to have to re-live. He managed to push out two more considerable logs, which accrued atop the already-existing pile, forming what looked like a brown, stinking mountain just beneath Tails' butthole. The executives by this point were more impressed than they were amused, and just wanted to see how big a pile one small fox like Tails could produce at one time.

One of them couldn't help but ask: "Mr. Prower, I don't mean to interrupt your... 'duties,' but I must ask, is it practical for us to expect that every energy bar one Mobian consumes will result in such a..." The executive searched for the right word, "'sizeable' bowel movement?" 

"Nng..." frrrrrrt-- Tails struggled to acknowledge the question he'd just been posed in between grunts and farts, "h-heh, I actually ha-adn't considered just how much w-waste one bar could produce.......but, it's kind of a good thing if y-you really think about it--" brt "--it r-really cleans your digestive system out..." 

The fox felt one last log of fox poop pushing against his tailhole, but only managed to expel clouds of hot gas for a solid minute. His mind started panicking knowing he was sitting in such a compromising position while nothing was happening, which was quite literally the only thing he preferred less at this moment than sitting in the same position with a lot happening. Finally, after what must have been almost two minutes, his tailhole eventually gave way and an enormous mass stretched his butthole into a perfect circle. He could barely get it to move along, it took almost another minute for it to actually get it out. He figured the last one must have been what remained of the now-digested and fermented bar. With one final blasting fart in the executives' direction, Tails had finished his "demonstration."

"Hahh..." Tails sighed out loud, hearing the room behind him giggle as he stood up and stepped to the side of the toilet. Looking down at the pile in the deposit area, Tails could see just how much he had to drop. "I was carrying all that in me?" Tails whispered to himself, his cheeks still burning red as he admired the pile. "R-Right," Tails said to the executives in front of him, bending down to push the button that would vaporize his waste. "This button right here is going to vaporize all of the...material." Tails pressed down and watched with the rest of the room as lasers emerged from the sides of the toilet's deposit area and charged up, soon shooting at the massive pile of fox business and making it glow red before...POOF! It was all gone! "A-And that concludes my demonstration, heheh..." Tails said nervously as the business people began to applaud the fox. 

"That was, uhh...certainly different from anyone else who's come to present to us, Mr. Prower," Mr. Davis said, trying to hold back his laughter in front of the embarrassed fox. "Your devices all worked just as you said they would, and I think they'd have the chance of being popular if we introduced them to the market." 

"R-Really?" Tails said, sounding excited, "you think so?" 

"Oh, I know so," Mr. Davis said, smiling to the young fox as he stood up and walked to the front of the room. "If you'll let us work with you on perfecting these inventions for mass use, I think we'll be able to make some arrangements in terms of letting you access the assets you were speaking of." 

"You will?!" Tails said, almost jumping up in joy. "Th-thank you so much, Mr. Davis, this really means the world to me!" 

"No no, thank you, Mr. Prower," Davis said, shaking his hand. "This is a day my colleagues and I will remember for years to come, so thank you for such an...interesting presentation, haha! Don't forget your invention on the way out, and we'll be calling you to follow up about this."

Tails turned around quickly to press the button that folds the toilet back up into a box, watching with the rest of the room as it folded up. The fox bent over to pick up the box, unaware his Tails weren't covering much... "Uh...Mr. Prower?" Davis said, smiling down to the fox as he picked the box up, "your...exit is quite messy from the demonstration. Feel free to stop in one of our restrooms on the way out to clean yourself up." 

"Oh!" Tails exclaimed, standing up quickly and turning his rear away from the audience before smiling sheepishly. "Th-thank you, heheh." Tails stepped over to where Sonic, Amy and Knuckles were waiting, blushing as he saw how embarrassed they looked. 

"Wow, Tails, that was..." Amy started, almost too embarrassed to continue, "that was really...something..." 

"Yeah Tails," Knuckles said, sounding more giggly than Amy, "you did a real nice job 'demonstrating', haha!" 

"S-Sorry I kinda ducked out on ya, buddy," Sonic apologized, scratching the back of his head. "I definitely owe you one, heheh."

“That’s alright, Sonic,” Tails said as he laughed awkwardly, trying his best to diffuse the tension. “Now, if you’ll excuse me, I think I need a little cleaning up…”
