Messification Magic
 
        Books. Lots of them. All of different sizes and lengths. One on top the other, stacked to form massive leaning towers that swayed back and forth with each hoofstep. Volumes upon volumes of anything a pony could ever want to learn about. From “Advanced Mathematics: Calculus made Easy” to “20 Amazing Magic Tricks that will Wow Your Friends”. A vast sea of infinite knowledge lined up on the densely packed shelves and spread across the floor. In the midst of this unkempt room was a lone cream colored pony sitting at her desk with her head buried deep in the well worn pages of an old book.
 
        She was always a voracious reader, but this book gripped her unlike most of the others she read. Her eyes scanned every word through her beat up old glasses.  Line by line, she absorbed every ounce of information, stopping only to make notations in the margins and in her notebooks. The pages lulled her into a trance of constant, undisturbed focus. She was oblivious to everything around her, even the faint knocking that grew louder with each passing moment.
 
        “Moon Dancer? You home?” A muffled voice called behind her oaken door.
 
        The busy bookworm snapped out of the spell she was under and rushed to the swing open the door. Standing on her porch was a perky purple pony wearing a lavender hoodie, standing in the cold.
 
        “I’m so sorry, Twilight! I was making some last minute adjustments to the formula and I just got carried away with-”
 
        “It’s quite alright, there's nothing to worry about. I wasn’t waiting too long. ” She calmly stated as she gave her friend a comforting hug, “C’mon, let’s head inside. I’m eager to see these new adjustments you have been working on.”
 
        The two ponies trotted into the house and sat on two cushions placed on the floor. Twilight levitated a menagerie of  textbooks, notebooks, scrolls and quills in front of them. They enthusiastically set up their notes from their previous study sessions. Moon Dancer magically picked up the materials she was working on a while ago and began to elaborate on the discoveries she had made.
 
        “Alright” she began, “Do you remember how during the last couple of experiments we conducted we had problems with the strength of the spell?”
 
        Twilight nodded with a frown, thinking back to the massive mess they both had to clean up as a result of their miscalculation.
 
Their protective padding practically burst, spreading fresh manure and urine all across the wooden floor.
 
        “Well, I found the perfect solution that'll allow us to harness the full potential of our messification magic” she said as the levitated the specific passage from the book for Twilight to see, “It’s a spell that will allow our diapers to be virtually leak proof. The only stipulation is that we need to be doubly padded for it to function properly.”
 
        “Really? Why would the spell necessitate that? Couldn’t it work with a single diaper according to these notes here?” Twilight inquired, pointing to the page that contained the spell.
 
        “Theoretically it could.” Moon Dancer replied while showing off her own notes now, “But in practice it would fail even more catastrophically than the last time. It keeps any waste expelled contained in the garment itself, but if it reaches beyond its maximum capacity, then the diaper would not just burst, but explode due to there being no other avenue for the growing mass to escape. With double diapers, however, the maximum absorbency would be increased tremendously, and, according to my calculations, it should be just enough to to hold whatever the spell could throw at it.”
 
        “That’s amazing!” Twilight applauded, “I can’t wait to put your hypothesis to the test.”
 
        “I’m pretty excited, too. I even bought some new diapers to ensure we have the best results. My research has found that the ‘Filly Fantasy’ brand is the most efficient one on the market currently. Plus they have really cute pink stars on them.”
 
        Twilight giggled as she tore into the plastic packaging to pull out four of the extremely thick diapers. She examined them looking at the cute frills and stars that adorned the padding. She rubbed them across her face to feel the soft crinkly fabric.
 
        “I am sure that the cuteness factor of this brand will surely aid in their performance.”
 
        “Absolutely.” Moon Dancer giggled as she took two of the diapers that her study buddy had taken out. “Let’s get padded up so that we can commence the experimentation.”
 
        With the finest finesse, The two ponies magically prepared their diapers for usage by cutting slits within the first diaper and layering it within the second. Then, they taped each one snugly around their waist.
 
        “Wow!” Twilight exclaimed as she got up to examine her poofy posterior, “Doubling the diapers makes them so thick I can barely walk!”
 
        Moon Dancer gave her friends rump a playful swat, but Twilight barely noticed with all the padding.
 
        “Thickness is directly proportional to capacity and time able to be spent in a diaper, so the thicker the better!”
 
        “Correct.” Twilight nodded in agreement as she sat back down. “Now let’s get down to business.”
 
        She levitated a notebook and a quill over to herself.
 
        “First, we must document our own personal data so in order to ensure that we are testing in a controlled environment. When was your last bowel movement?”
 
        “Exactly two hours and thirty-four minutes ago.” Moon Dancer stated matter-of-factly.
 
        “Last meal?”
 
        “Dandelion sandwich with a side of potato chips and chamomile tea to drink. I ate it exactly four hours and fifteen minutes ago.”
 
        “Have you been having problems with irregularity?”
 
        “Nope. My movements have been consistent and regular.”
 
        Twilight continued asking question after question, pausing between each one to record the information down into her notes. After the data collection was complete, Moon Dancer did the same for Twilight.
 
        “With that out of the way” The purple pony said as she rose up and cleared the working area away, “We can move on to the funner part of this experiment. Do you want to go first or shall I?”
 
        “After you, Twi. I am all yours.”
 
        Twilight braced herself as her horn lit up. She concentrated hard, focusing all her magical energy into her test subject. A glowing aura surrounded the entirety of Moon Dancer’s body, then dissipated in a blindingly bright flash of light.
 
        Both of the ponies stood in silence as they waited for the effects of the magic to kick in. Seemingly nothing had changed at first, but a sudden, loud rumble broke the stillness that filled the room. Moon Dancer recoiled in pain and let out several loud grunts as she felt her stomach gurgle and churn. She pushed as hard as she could to rid herself of the uncomfortable pressure that grew with each agonizing moment. After a few moments, a strange peace washed over her despite the fact that she had not relieved herself at all.
 
        That, however, was just the calm before the storm. In that moment all control of her bodily functions was lost. Her doubled diapered butt began to expand at an alarming rate. Massive continuous logs of feces coiled into the pristine padding. The semi-solid mass mushed against the diaper as more poop flowed in. The gooey chunks spread far across the front and back of the diaper to make room for the seemingly endless deluge of waste. A steady, strong stream of urine joined the filthy mixture as it showered into the thirsty garment. The yellow liquid penetrated the brown, poopy layer and was absorbed by the first diaper. It swelled up until it overflowed into the next one, filling it up the same as the last. A relatively deep puddle formed at the base of the diaper, but was held in thanks to the spell Moon Dancer discovered. The pee had begun to subside, but the solid mess was still steadily coming in. Piece after piece of the soft fecal matter loaded the diaper up to the very brim, and didn’t stop until it was visible from beyond the double layered padding. No normal pony would be able to ever excrete this much from their bodies, but with the help of their very own messification spell, it was now possible to completely augment anypony’s messing capabilities.
 
        Moon Dancer, still a bit unsure if she was done or not, moved her hoof to touch her diaper, but was quickly stopped by Twilight.
 
        “Wait a moment. I know you’re eager to give it a feel, but we need to run some tests first, and I don’t want any variables skewing the data. We might have actually succeeded in perfecting this magic this time around and we need to record the results in as much of a controlled environment.”
 
        “Yes, of course.” Moon Dancer embarrassingly said, “I guess I just got a bit carried away and forgot about the basics of the scientific method.”
 
        “That’s quite alright. I know if I was in your place I would feel the same way.” Twilight comforted before moving on, “We need to run some stress tests to see if there is any chance of a potential for leakage. After that, I would need to give you a quick questionnaire to gather data on your own personal experience and feelings of undergoing the spell. Lastly, we would need to measure your enjoyment levels of the overall experience before replicating this experiment with me as the subject.
 
        “Excellent plan, Twilight. What specific trial would you like for me to do first?”
 
        “You can start by doing some walking around. A very basic task, but important in finding out if this magic is practical in even the simplest of movements.”
 
        Moon Dancer nodded and began to waddle around the room to her best abilities. Each hoofstep caused the contents of the diaper to slosh around, but the was absolutely no signs of spillage from the drooping diaper.
 
        “So far, so good.” Twilight commented as she scrawled her observations into her notebook. She moved in close and put her hoof on Moon Dancer’s soiled padding. “Now I am going to apply pressure across the diaper to check for leaks before moving on to the most rigorous test.”
 
        The purple mare gently massaged the front of the diaper and worked her way around, carefully observing the possible leak points. Moon Dancer’s face turned redder than the colorful crimson streaks in her mane as she felt her friend's sweet touch. Twilight noticed this and smiled softly to herself. She was definitely enjoying the testing just as much as Moon Dancer was. After a while of examining the heavily sagging garment, she took her hoof off and began writing in her notebook again.
 
        “Nope, not a single leak. This is going great. Time for one final test. I need you to sit down and squish your diaper as much as possible on the floor to ensure that nothing will leak out of it.. Is that alright with you?”
 
        “Absolutely!” Moon Dancer ecstatically replied, “It would be my pleasure!”
 
        Twilight grinned as she eagerly eyed the cream colored pony squatting down into position. Moon Dancer dropped her padded booty onto the cold, wooden floor beneath her. She rubbed as hard as she could, enthusiastically spreading the mess all across her filthy flank. Each loud squelch made it clear that mess was coating her entire crotch a deep shade of rich, dark brown. She used both her hooves to squish the mess even more, desperate to feel as much of the poop as possible. Her whole body rocked back and forth until she became too tired to continue. She laid herself down on the floor to rest for a moment.
 
        Twilight moved over to the poopy pony and began to give the messy diapers some more playful rubs as she checked for any leakage. With one final pat, she picked up her notebook and wrote down the results.
 
        “Success! There was no sign of leaks or spillage and the padding remains intact after heavy interaction and movement!”
 
        “That...Is...Fantastic!” Moon Dancer replied between her heavy panting.
 
        Twilight gave her dirty friend a moment to recover before continuing with the rest of the data collection.
 
        “Alright, you ready for the questionnaire?”
 
        Moon Dancer breathed out a relaxed sigh.
 
        “Yup. Lay it on me.”
 
        Twilight cleared her throat and began the interview. She asked question after question, inquiring about various topics like if she felt any extreme pain or discomfort during the process or if she experienced any strange side effects as a result of the magic. Moon Dancer answered honestly and stated that everything was normal as far as she could tell. Twilight finished writing down all her responses before moving on to the final part of the data gathering.
 
        “Okay, now on a scale from one to ten, tell me how you would rate the overall enjoyment of your experience and elaborate on what you like the most about it.”
 
        “Ten out of ten, hoofs down! I would rate it even higher on that scale if it were mathematically possible for the data gather purposes. The huge feeling of release coupled with the immense pleasure of having a impossibly filthy diaper is unlike any other feeling I have ever experienced! Pure stinky bliss.”  
 
        Twilight smiled as she giggled at her friends answer.
 
        “Great, that’s all the data we need.” She said as she closed her notebook. “Now it’s my turn to partake in the fun.”
 
        “And I’ll record my observations. My very detailed observations.”  Moon Dancer said with a sly wink.
 
        The filthy filly went through the same steps that her clean counterpart went through in preparation for the tests. With the questioning out of the way, Moon Dancer began to perform the messification magic on Twilight. Her subject went through a similar experience, except that she didn’t feel as much discomfort from the spell. She thought that is was most likely due to the fact that she was an alicorn and was more resilient to magical effects, but that theory was soon dismissed when she saw what was going on in Twilight’s diaper. Moon Dancer stared at the awe-inspiring scene unfolding before her.
 
        Twilight had to squat down due to the great force of the poop rushing out of her diaper. The mushy mess spread so fast that it looked like a small bowling ball had been dropped into her poofy padding. She completely filled every nook and cranny to the very brim with her solidus slurry of smelly feces. Gooey, slimy scat spread across her purple butt and showed no signs of stopping. A resounding hiss could be heard as the pee began to join the filthy party. Both thick layers of padding happily did their duty as they absorbed the urine along with any of the liquefied poop. After what seemed like an eternity of excretion, the foul flow finally came to an end as the padding reached well beyond its maximum capacity.
 
        Both of the ponies stood flabbergasted at the result of the spell. They knew it could enhance natural messing potential, but this was beyond their calculations. It was a miracle that the diaper itself didn’t burst under the immense pressure.
“Well...Uhh...Wow...That’s quite the...Umm...Load you got there.” Moon Dancer commented through the stunned silence, “You wanna do some testing now?”
 
        Twilight took a while to process everything that had just happened, but then gave a wide smile and nodded her head as she thought about the implications of the results. Not to mention the fun to come.
 
        “Yes! This phenomena needs to be tested! If this magic combination can really allow for this much capacity with only two diapers, then who knows what corollaries could stem from this!”
 
        “Indeed! Now let’s begin!”
 
        Moon Dancer ran Twilight through the waddling test and noted down that there had not been any signs of leakage. Then she put her hoof onto the pooped padding and smushed it around as much as possible. Each hard press made Twilight moan a bit. The crinkly fabric felt so soft and warm to the touch. The cream coated mare squeezed the diaper to her heart's content, but no leaks were detected.
 
        "Talk about impressive! Everything is performing well beyond our expectations!” Moon Dancer exclaimed in astonishment at the resiliency of the padding, “Time for the real test to begin.”
 
        Twilight was already preparing to have some fun on the floor while her science partner was busy recording the data. She pressed the brown stained undergarment onto the floor and rubbed it in as much as possible. At first, she started off slow, savoring the delightful feeling of the filth spreading far and wide. Then she picked up the pace and let herself get lost in the wonderful sensation. Moon Dancer put down her notebook and joined in on her raunchy rodeo. The two ponies ground their smelly butts on the wooden floor of the cottage, stopping only occasionally to grope each other’s dirty diaper. The two ponies played in their poop until they were fully exhausted from the strenuous squishing. They breathed heavily as their bodies rested on the floor. After a bit of resting, Moon Dancer began to speak up.
 
        “Should we record our observations now and move on to the next step of the testing? There is so much to record! So much expand upon in other trials! So much science!”
 
        Twilight smiled at her friends drive to continue, but she had other plans in mind.
 
        “How about we take a much needed break? I am positively pooped, both literally and figuratively.
 
        They both giggled quietly in response to the cheesy joke.
 
        “Yeah, you’re definitely right.” Moon Dancer replied as she pulled herself and Twilight off from the floor, “How does snuggling up on the couch with some hot cocoa and video games sound? I just bought the new downloadable content for Moonborne, and I know how you have been itching to give it a try.”
 
        Twilight’s face lit up like the Hearth’s Warming Eve decorations that adorned the streets of Canterlot.
 
        “I can’t think of a better way to sit back and relax. Should we change before we start?”
 
“And waste four freshly soiled diapers? I don’t think so.”
 
        “You're right.” Twilight agreed, “ There is still plenty of fun to be had. Maybe we could measure that true limit of these diapers with a some more extensive testing. What do you say?"
 
        "I say that sounds like an excellent plan. I'm ready to take these bad boys way past their breaking point, even if it means cleaning up a stinky manure pile later."
 
        "Perfect then. I’ll get the game set up, you start the chocolate, deal?”
 
        “Deal.”
