A very ancient chaotic magic has been unleashed upon the world, the kind of magic that would make Discord green with envy, and on top of that, this magic is going to bring out the madness in everyone.

For the longest time Sunset believed that the only magic that was in the human world was just the magic that she brought over to it. She didn't believe that there had actually been magic before. Nor did she believe that said magic only needed a small push to release itself again. But now evidence to that fact has come in the shape of a small wooden mask, a mask that grants the truest desires of the individual wearing it, releasing their truest selves without filter upon the world. And for good, or bad, this insanity is going to spread its influence one life at a time.

Loosely inspired by Nico-stone Rupan's Sour Sweet Stories

Author's Note

(AN: So, you're about to read this huh? Well, just know that this is written purely out of boredom. It was random, just something that popped into my head, and to be honest, i'm likely to take it down at some point. Add to the fact that I'm a little tired, and I'm working on junkfood and caffinee at the moment. Both of which are fine alone, but no something that should be consumed in large quanties together late at night. So, enjoy, and may God have mercy on my soul for writing this)

Chapter 1: Wallflower Blush

The Strange case of the ID

A The Mask and Equestria Girls Short crossover

Chapter 1 Wallflower Blush

Magic, the word once brought images of illusionists, great stage performers that tickled the senses, and tricked the mind with slight of hand, some mirrors, and lots of prep time. But shortly after the portal to another world was found it was obvious that magic was a tangible force. That magical spells existed, and people could transform into strange new beings without issue. The mundane no longer had the choke hold it did on the world. Now there was evidence of the existence of something more than the drab and dreary daily grind.

Perhaps it was the fact that belief in magic that gave it power, or maybe it was simply waiting in the wings, but regardless magic from what was once believed to be a purely mundane world presented itself in the most unlikely of ways. It was the final year of highschool for Sunset Shimmer, Pinkie Pie, Rainbow Dash, Twilight Sparkle, Fluttershy, Applejack, and Rarity. As such it was also the graduation year for Sunny Flare, Indigo Zapp, Sour Sweet, Lemon Zest, Sugarcoat, and Second Person.

For Crystal Prep the graduation was more of a standing tradition, a mark determining the final days of what could be considered a childhood, and marking the beginning steps into adulthood. In Canterlot High it was much the same, with the exception of a Violator Cupcake monster that was created by leaking equestrian magic that happened to inhabit and animate a collection of cupcakes that had been made.

“Cupcakes aren’t supposed to do that!” Sunset Shimmer screamed as the tentacle beast wrapped around her, laughing, holding her above the ground.

The cupcakes themselves had joined together to form a single being, and it had apparently taken the abridged lessons of how to become a nineteen nineties hentai tentacle monster. Luckily the gems, mixed with their own pony up powers, were managing to slow it down, and she could see the very magic that formed it was slowly leaking out. Still, she was being suspended, half naked, with two tentacles being way too familiar.

No one could blame them for never noticing a softly glowing wooden mask. After all, there was a candy colored, gigantic, hentai inspired cupcake tentacle monster that was currently attempting to violate Sunset Shimmer, that had managed to drag head of horticulture club, and prize flower organizer, Roseluck from the green house with her screaming “The horror, the Horror!” at the top of her lungs until she passed out.

No one noticed the mask, no one paid it any mind. After all, it had been found in the river, cleaned, and slapped onto an art project by Sandlewood. The project, aptly called ‘Trash - Man’ was bringing notice to the amount of pollution found in the river of Canterlot City. Of course he had no idea what the mask truly was. After all, it had simply been floating along on the river itself connected to a few trashbags, a couple of old torn workshirts, and some old fishing line that managed to come together to almost make a humanoid shape. Thus, it was the inspiration for the art piece.

It was an art piece that managed to get him the passing grade he needed to actually graduate without having to attend summer school, and of course that was the graduation that was currently being interrupted by the tentacle monster that had went from attempting to violate Sunset Shimmer, and Roseluck, to aggressively attempting to violate Sunset Shimmer and Roseluck. In an attempt to save as many students as possible, and to keep out of the way of the girls handling the crisis, Principal Celestia had everyone enter into the school, getting away from the tentacle monster that was intending on living out its hentai dreams.

Entering into the school everyone watched from the perceived safety of the large glass doors, and unfortunately it stretched back far enough that some couldn’t see out. Such was the luck of Wallflower Blush and Wiz kid. The two of them couldn’t see, and in an attempt to politely move forward the art projects were bumped into.

At first it appeared that no damage was done, but sadly that was not the case. As the sound of something clattering to the floor could be heard. Wallflower looked at the mask, its glowing inner surface was practically speaking to her, and she lifted it up. She looked at the inside of it, no longer interested in the world outside, and she could practically hear the promises of anything she could ever want.

She grinned, pulled the mask on and a jolt of energy shot through her. The mask became a living being, wrapping around her head, causing her to scream in fear, and she attempted to pull it off, only for it to remain in place, enclosing around her head with ease. She felt herself spin in place, but not a quiet, soft spin, but instead it was as if her body was attempting to reproduce an imitation of a hurricane or tornado. Lighting began to flash around her, and she felt her body change shapes.

She’d never been exactly blessed with classic beauty looks. Her chest was always a little flat, she was thin, but not exactly in shape, and her hips were a little narrow. She felt her hips widen, her breasts grew like two water balloons, and she felt her waist draw in on itself until it was practically gone. In truth, the way she looked was physically impossible. She, on some internal level, understood that her body shape was that of an oversexualized cartoon from the golden age of animation.

Her clothes changed as well. No longer was she wearing her striped sweater and blue jeans. They transformed into a flowing red dress that was slit up the side until it reached just below her panty line. The spinning stopped, and she didn’t feel dizzy, instead she felt amazing! She felt powerful, she felt sexy, she felt beyond amazing. Her brown eyes shined with mischief and she laughed.

“It’s party time!” she exclaimed, “That’s P A R T Y, because I gotta!”

With a laugh she looked above her, jumped, while reaching behind her back, and pulled a sledge hammer from the very voids of space where the fifth dimension, the dimension where imagination ruled all, existed and slammed through the roof of the school and landed on top of it. She looked at the cupcake monster, seeing the destruction, and a slight frown appeared on her face.

“Hey! No fair having all of the fun yourself!” she shouted.

To its credit the newly formed hentai nightmare heard the sound of something new, looked up, and saw the overly sexualized new prey. It puffed itself up, ready to take her own, only to find that its new prey had reached behind its back and pulled out what looked like balloons. It continued to attempt to violate the two girls in its grasp while the others attacked it, but it was confused as to what this new prey was doing. Until the new prey had tied the balloons into the shape of anvil. It jumped, effortlessly, over it, and the balloons popped creating a very real anvil, with the words ACME Corporation on the side, which the new prey then dropped onto the cupcake monster.

The force of the anvil drop was great enough that Sunset was thrown free of the cupcake monster, and at the same time so was Roseluck. Seeing Roseluck heading toward the building the Mask, which was currently Wallflower’s unleashed ID, rocketed forward as fast as she could. She hit the wall of the school, indenting the brick, knocking much of it loose, and she pulled herself away from it with a laugh. She shook, giggled, and looked at the falling Roseluck again. She reached behind her again, and this time she pulled out the single largest coconut cream pie ever known to man. It was eight foot wide, six foot deep, and was simply made to perfection. Roseluck hit it dead in the center and the cool coconut center managed to slow her, absorb the impact perfectly and of course spray coconut cream pie all over the seven girls who stood in awe of what just happened.

The mask put the tin down with a very knocked out Roseluck inside of it, fished her out, and then looked at the others as they stood there.

“Wow, looks like I cream pied all of you, and I didn’t even go futa!”

They stood there, but Pinkie Pie giggled, “Silly, the author of this story might be cool with the idea of having a lesbian orgy when the plot line calls for it, but that is so not this moment!” she laughed, “and besides, he figures that you’re most likely going to hook up with Party Favor, because he really compliments you because you’re kind of quite and reserved, and he’s an extravert on a huge scale!”

“Eh, maybe,” the Mask said, “but right now Mama wants to go clubbin!”

With that she laughed, once again reached behind her, and pulled a nineteen ninety-six Harley Davidson FLSTF Fatboy out from the same place the sledge hammer, balloons that became the anvil, and the gigantic coconut cream pie had come from. She hopped onto it, her clothes changing mid jump from the revealing red dress to white motorcycle suit with a cape behind it, the edges covered in mock flames, and the note, this suit belongs to Evel Knievel, don’t touch! Sewn onto it. She started to motorcycle, and then sped off from the group of girls.

“Ummm, Sunset, darling, what kind of Equestrian Magic was that?” Rarity asked.

Sunset stood, pulling her pants up, which was now filled with frosting, and shook her head, “I have no idea, but we can’t let her get too far, whatever that thing is, I’m sure that it’s most likely dangerous, I mean did you see it bring everything out from practically nowhere?!”

The girls ran to the van that Pinkie Pie had bought, which was an older Volkswagen minibus that had seen three owners, over two hundred thousand miles, and more garage bands inside of it than anyone could truly guess. It started on the second try, and then they took off in the direction that the motorcycle had headed. It was too early for clubbing, there wasn’t any that was actively open. But the direction they were heading wasn’t exactly a clubbing area. It was an area of gated communities, well to do individuals that held socially acceptable positions of power in the local area.

They saw the motorcycle, which had somehow been buried into the back of a school bus, which had been flipped up on its side, and the word painted, in bright pink, “I used the backdoor!” Pinkie Pie couldn’t help but giggle. They looked at Crystal Prep Academy, and the seven of them heard the sound of shouts and screams from inside. They rushed in and found Wallflower Blush on the ground. She was groaning, but looked unharmed. They could see the clothes she was wearing, which had been the white motorcycle suit, was slowly turning back into her own clothes.

“W..what happened?” she asked as she looked up.

“We’re not sure,” Sunset said, “but whatever it is has gotten loose over here.”

“Somebody Spank Me!” a voice shouted with a laugh from deep inside of the school.

“And it’s somewhere over there.”

Chapter 2: Second Person

The Strange Case of the ID

Chapter 2: Second Person

Crystal Prep was a multitude of things. It was a formidable facility dedicated to the molding of young minds for a future set in path by their parents, business owners, and civic leaders. It was a highly regarded Five A school private school, which meant that it could handle a large number of students, offered the most advanced curriculum, and had the most up to date texts available to the civilian education market. To say that it was a cut above other schools would be an understatement that could, and would, take the cake of all understatements.

However, the one thing that Crystal Prep lacked in was the Magical Attack Preparation Plan, as developed and enacted by Principal Celestia. Such plan followed other protocols, to be sure, but it also had specifical details on where to send students, which councillors would have the students best interests at heart, and would, of course, be willing to keep an open mind, and of course a closed mouth about the ongoings at the school itself. The councillors Principal Celestia had chosen were mostly those who were left overs of a dying breed that had been teenagers in the 1960’s.

They had experimented with various lifestyles and ideals that their minds were open, and they absolutely understood the idea of keeping their mouths shut. After all, the last thing that any one of them wanted to do was alert the man onto something strange that seemed to work itself out fine. Plus, having grown up in the sixties they completely understood how the government would work toward something it didn’t understand. Unfortunately Principal Abacus Cinch had never made those contacts. She didn’t have the magical preparation plan, because her students were exposed to it only once, and that was at Canterlot High.

Instead, she had resigned herself to deal with issues as they came. Tradition was far more important to her than whatever supernatural aliment was happening at Canterlot High. Her students would simply remain separate, and at no time would they engage with Canterlot High’s students unless it was deemed absolutely necessary.

It was for this reason, and none other, that Crystal Prep was caught with its metaphorical pants down, bent over, with its cheeks spread. The moment a girl with a strange elastic looking green mask covering all of her head, except for a small area where dark green hair stuck out in a ponytail. She wore a white leather motorcycle suit that had flames stitched into the seams, a cape flowing behind her, and the note this suit belongs to Evel Knievel, don’t touch! Sewn onto it. She let out a laugh as she began to strut down the hall of the school as if she had belonged there.

Upper Crust saw the unknown newcomer, realized that no one else was going to say a word, and stepped forward. She looked at Jet Set who nodded, and ran to tell the security guard. She studied the girl, uncertain of who she was, but figuring that she must have come from Canterlot High. After all, she looked to be their type.

“Excuse me,” she said, “But your kind aren’t allowed here.”

The girl looked at her, smiled brightly, and managed to slide her left foot toward the right, doing a perfect split, picked herself up, and then reached behind her, pulling out two maracas from someplace that Upper Crust couldn’t see, understand, or want to understand. The girl then shook the maracas, and as she did music began to pump through the PA system.

“They call me Cuban Sweet,” she began, “I’m the master of the Rumba beat.”

Within seconds Upper Crust was dancing the rumba, her top missing, she was laughing, singing, and practically everyone else in the hall had joined in. The entire hall was a mess of discarded uniforms, scantily dressed teenagers, and all of them dancing a style of dance to a genre of music that’s only reference to any of them were some old golden age of animation cartoons in which a wolf was attempting to pick up an attractive redhead. Yet somehow all of them were dancing on beat, singing perfectly with every line, and more to the point it was pulling other people out of class rooms.

The sound of the music, the magic of the dancing, and the inspired singing found its way toward the administration offices and caused Principal Abacus Cinch to step out of her office, and into a liability nightmare. At this point there were at least a hundred students, all in violation of the dress code, dancing the rumba, singing a ridiculous song, and making a mockery of Crystal Prep! She stepped forward, completely planning on taking the bull by the horns, returning order and tradition where it belonged, and ensuring that the guilty party be expelled for this massive disruption. That was her plan, but then Principal Cinch had never personally been forced to deal with magic with the exception of the Friendship Games.

She had no idea of knowing that there were two magics working together, and one was feeding the other. Harmony magic gripped her, and soon she was singing the ridiculous song, her jacket open, her power heels forgotten, and there was the security guard who was holding onto her as he danced the rumba with her. It spread past her, infecting all that came into contact with it, and one teenage girl that had managed to go back onto her meds and keep the hallucinations at bay was wondering if all of this was real.

Beside her, her best friends were dancing, all looking uncertain, but belting out a song they had never heard before a day in their lives. She saw her boyfriend near her, glad to have him, and watched as he moved further into the mess of teenage bodies. He moved toward the girl dressed in the motorcycle suit, waving the maracas, and he felt his hands reach up. A sort of pull directed him, and he grabbed the back of the mask. It came off easily in his hands, and the girl fell to the ground. Everyone slowed, stopped, and he looked at the back of the mask. He could hear the promises.

He could be as athletic as his brother First, he could be anything and everything that Sour could ever want. He could be as popular as he ever wanted to be, and he would have the power to change his parents if he wanted. It would grant him his every single desire, everything he could ever want, and he just had to put it on. He lifted it, and like with Wallflower Blush it latched onto him. He let out a yelp of surprise, but he didn’t fight it as it surrounded him with a rainbow. When it cleared he was slightly taller, his muscles now defined to the point that it looked cartoonish and fake, and he was wearing a latex bodysuit with zippers near his crotch. The mask itself had reached deep into his truest self, and unleashed that upon the world.

He laughed maniacally, sounding more like a cartoon villain from something that his uncle might have watched on saturday mornings back when he was a kid. He moved faster than he’d ever moved in his life, faster than most people could ever move, and in truth fast enough that it caused the very tiled floor under him to crack, break, and go flying with each step. He skidded to a stop near Sour Sweet, causing her eyes to widen as she took in the form before her.

He changed from the full latex bodysuit, to that of a pair of white slacks, form fitting blue shirt, French beret on the side of his head, and his abnormally large and sparkling white teeth were shown in the most over exaggerated smile she had ever seen.

“Ah, my Sour Sweetheart, come with me, and I shall fulfill your every desire,” he said moving toward her, “We shall live in a palace of pure love and sex, with a heavy helping of sex, and it shall never end.”

She backed up, “Second?” she asked, “Is… is my medicine not working?”

He moved closer to her, his smile actually touching the corners of his eyes, “No, they’re working, but I can be everything now,” he said, “With these powers I can be a superhero!”

He laughed, “I can protect the innocent, right wrongs, promote world peace and total equality regardless of gender, ethnic background, and financial standing!” he exclaimed before he looked at her, and he stepped closer to her, boxing her in, invading her personal space, and being a bit more aggressive as she stated that she thought he should be from time to time, “but first I want to do like we discussed in our world history, divide and conquer, Je t'adore, Je t'adore, Je t’a window, I don’t care!”

He expected a few things, and one of the things he expected happened. Sour slapped him, and of course his new found powers, and maniac responses, reacted as one would think they would. His entire face turned toward the direction of the slap, his cheek practically warped around his nose and mouth before righting itself, and he looked back at her.

“You are so coy, I love it!”

“You’re acting like an unhinged lunatic right now,” Sugarcoat said, “And honestly it is frightening everyone.”

He looked at her, “Ah, direct to the point,” he said as he spun and when he stopped he was dressed in a charcoal gray suit, a pair of glasses adorned his face, and there was a fake cigar in his fingers, “I believe that the father of psychotherapy would be proud of you.”

Sugarcoat stepped back, uncertain of what was going to happen next. With the other girl, she had just appeared and all of them had danced and sang. It was like a party, and almost like she was living out some kind of fantasy where she was the very life of the party. With Second it was odd. He seemed focused on Sour, but he was reacting to all of them in an incredibly over the top fashion. He moved from her, his clothes altering and changing again, changing into a dog collar, leash, pair of spandex boxers that fit way too well, and the leash curled up into Sour’s hand as she stood there.

“Second?”

He grinned at her, turned around, and grabbed his ankles, “Somebody Spank Me!”
