1. A Dynamic Duo

In a secluded part of the Canterlot Castle, a pair of sisters could be heard arguing into the wee hours of the morning. Both Luna and Celestia wore matching business suits, one porcelain white with a black tie, and the other charcoal black with a white tie. They were more akin to a pair of directors than royal sisters, as if on their way to have a conference meeting over sales figure than presiding over a country.

“This is most troublesome news sister. However can we save the show in this dire state?” Luna lamented to her sister, looking over the abysmal ratings for the new version of My Little Pony.

“I’m not sure Luna, we did the market research and it said that this show would be a hit. I mean, card games, who does not love card games, on motorcycles even! Maybe we need to bring in an older crowd, win back the audience,” Celestia said, thinking out loud as she went over the figures. “What’s selling these day?”

“Well in my extensive research I have come up with a few… radical designs that we could use, if we are to go to such an extreme.” Luna replied as she turned her laptop over.

“Remind me to burn that laptop of yours once this meeting is done, and then throw the ashes into the deepest pit in Tartarus.” Celestia sighed as she looked over some of the designs Luna was showing her.

Celestia weighed the options in her head. The show needed to continue for Equestria to survive but this might be pushing the boundaries. Still…

“Okay get these designs to marketing, we need to have them up and running by Friday.”

“Very well, but we have to do something about the cast as well. Twilight is quite the draw, but I feel like putting her in this new scenario seems like a big stretch.” Luna commented as she exited the room.

“Ugh, fine. You got executive control for this one.”

Luna nodded and smiled slyly, which gave Celestia a long shiver. It has been a while since the embodiment of the night was this eager for a project, and the last time she was Discord had a field day.

“Just don’t go over our budget,” Celestia said, hopefully reigning in Luna, at least a little, as the Princess of the Night left for marketing and to enact her new vision for the show.

“So Twi, any idea why Luna wanted us so badly in her castle? I mean it’s not like her to keep us in the dark.” Dash asked Twilight, the pair very much perplexed as to why Luna was so desperate to meet them yet also insisting they not tell the others about this visit.

“I’m not quite sure, Rainbow, but I bet it’s for a very good reason,” Twilight replied absentmindedly.

“Maybe she has something that’s important to national security or the like.” Twilight said, trying to think of an excuse.

“No way, I am in the Wonderbolts remember? If it were, I’d know…” Dash chuckled, as Luna opened a door further down the hallway.

“Come in quickly, there is little time to lose!” she proclaimed with great concern, as the pair ran into the darkness.

The two mares hurried quickly into Luna’s dark chambers. Whatever was going on must be important for Luna of all ponies to act this way. The room they entered was bare and stark, with only two chairs in the middle of it, and overhead the a single light in the room.

“What’s the matter Princess?” Dash asked. “Are the Changelings back?”

“Or did Tirek escape again?” Twilight added.

“Or are there weird hairless space apes invading the capital and destroying everything with giant laser guns?” Rainbow Dash continued, having read far too many comic books.

Luna and Twilight shared a couple of blinks before the Princess of the Night continued on.

“No, nothing as simple as some season finale big bad.”

“Season finale?” Twilight asked, “What’s going on Princess?”

“Ah, never mind that, quickly sit down so we can save Equestria!” Luna chuckled a bit before the pair indeed sat down, now more perplexed than afraid.

“So what’s so important we need to discuss Princess?” Twilight asked again. The chairs felt weird, like some kind of slime was over them. She shifted in her seat, trying to get comfortable but to no avail. The same thing seemed to be happening to Rainbow Dash as she too squirmed in her chair.

“First allow me to slip into something more appropriate for what is about to come next.” Luna smiled as both feet and hands of the pair were strapped onto the chair by clasps. Luna herself began to shine, a black liquid covering her body with ease and worse yet, a smile on her face Twilight or Dash had never seen before.

“Argh! It is a trap!” Twilight struggled against the bonds. “Who are you? The real Princess Luna would never do anything like this!” Twilight screamed. She tried to use her magic, only for her horn to do nothing, as if the magic was never there in the first place.

“That is not going to work, I took the liberty of disabling your special effects, and those of Dash too. So no flying for now Miss Tomboy.” Luna laughed, enjoying herself way too much in the situation.

“What the hell are you talking about?” Dash yelled back at Luna. She tried to get up, but the chair seemed to spring to life, her restraints keeping her pinned to her chair, forcing Dash back into her seat.

“Luna, or whoever you are, you’d better let us go,” Twilight threatened, though she had nothing to back it up with. “When our friends find out we’re missing, there won’t be a force in Equestria that could stop them.”

“Ah yes, how very heroic of you Twilight Sparkle. Celestia really did design the perfect role model.” Luna began her monologue, as small patches of Luna’s black rubber suit slowly dripped from her fingers, slid over the floor and creeped over, beginning to coat both Twilight’s and Dash’s fingers.

“And let me guess Dash, you were thinking of some one-liner?” Luna continued on, as Dash stopped mid breath.

“...Okay whoever you are, you are scaring me.” Twilight admitted, her mind unraveling as she felt her hands getting tightened by some alien fabric.

“What is this?” Dash said as she tried to wipe the weird patches forming on her fingers, unsuccessfully. In fact the patches started growing and spreading. In a few minutes Twilight and Rainbow Dash’s entire hands were coated in the stuff as it traveled up their arms.

“It’s your new costume Rainbow Dash, though I suppose I’ll have to call you something else in a few minutes,” Luna replied ominously, grinning at the two trapped mares menacingly.

“Don’t worry, it’s a painless process, it should only take a minute or two.” Luna continued as the rubber suit moved on, moving past the shoulder blades, destroying the clothes that it came in contact with.

Dash began to feel an alien sensation, as her wings were being pressed by this crimson red fabric her body was being covered in, and in moments she felt something she had never before, a total lack of them.

“What did you do?!!!” she screamed, almost breaking her wrists as she struggled in vain against the restraints.

“I simply removed an unneeded design element, earth ponies do so well with the more adult demographic.” Luna replied coldly, as two rings appeared above the pair, with Twilight already looking desperate.

“At least tell us what are you doing.” she said resignedly.

Luna sighed. “I guess I owe you that much, you have been a predictable heroic do gooder, but also a damn good one. Twilight Sparkle, I am afraid to tell you that you, that cyan nutjob, and everything you ever knew and loved was fabricated by me and Celestia.” Luna said calmly, letting that fact sink in, as the suits formed over them entirely.

“What?!” Twilight said, astounded. The suits were identical in every way to each other, the only difference being their color. Rainbow Dash’s was red while Twilight’s was a deep violet. “How is that even possible?”

“Afraid so, dear. Your body, your demeanor and your destiny has all been written by us two. Hell I can give you a transcript of the last 9 seasons if you want. And I am afraid you and your equine power rangers grew stale, so my sister allowed me to recreate a new Equestria, with a new duo to have fun and enjoy. Only my vision of this world is a whole lot more perverse.”

The rings began to touch the pair’s ears, and Twilight knew whatever was coming next was the end for her and Dash.

“See you on the other side girls…” Luna smiled as the rubber covered their heads.

The rubber pushed down on Rainbow Dash’s head. She tried to struggle, but with her hands cuffed there was little room for her to move as the ring continued downwards.

The rubber stuck to Rainbow’s head, creating an odd sensation as it did. It soon passed over her eyes, which she instinctively closed, but soon after opened them. She could see like normal except there seemed to be some kind of film over them, only barely perceptible. But that’s not the part that worried Rainbow Dash the most.

The ring was slowly going over her mouth and nose. It soon covered her mouth, forcing her jaw shut. She panicked for a moment as she thought her air was cut off, only for her to resume breathing through to small holes in her nose, but her mouth was effectively silenced.

The ring finished up, pulling down the rubber to met up with the rest of Rainbow Dash’s suit, and a small flash came, severing the rubber ring and fusing the mask to the rest of the suit.

Rainbow Dash tried to move, to get out of her restraints but it was no use, they would not budge.

“Stop resisting,” a voice came into Rainbow’s head.

“Who’s there? Where are you?” Dash tried to reply, but with her mouth sealed nothing came out.

“Don’t talk,” the voice ordered and Rainbow fell silent. It felt good for some reason.

“Just relax,” the voice continued. “You’re going on a wonderful journey, the journey that will make you me.” She said very seductively.

“Wait what!?” Dash tried to yell, but a quick sharp shock overcame her body.

“What did I tell you about talking?” the voice went on. “See that’s what happens when you don’t listen to me. Now let’s try this again, relax.” the voice said more commanding this time.
Rainbow Dash’s muscle loosened. She wasn’t going to get a shock just for keeping her body tensed. At that moment a way of bliss swept over Rainbow’s body, almost like the exact opposite reaction to the shock she had received.

“See that’s what a good pony gets.” The voice went on. “But I can make it both a thousand time better and a thousand time worse. Now let’s start with your name. What is it? Just think the answer.”

Rainbow Dash Rainbow thought, before her body was wracked by another intense shock.

“Oh no, wrong answer. Your name is Dream Searcher. Dream Searcher, repeat it for me.” the voice went on.

My name is Rainb- the thoughts were cut off as pain shocked her once more.

“Tsk tsk tsk,” the voice scolded her. “Maybe a refresher course on who you are would be better.”

In front of Rainbow Dash’s mind came flashes, memories, but not her memories.

“You are Dream Searcher,” A flash of a yellow coated and yellow maned pony passed in front of her. “You are a hypnotherapist. You like controlling ponies, making them yield to you.” Images of ponies falling under the mare’s watch and the mare commanding them in a mindless daze passed before her. The suit started pumping pleasure at Rainbow, the most intense sensations coming from her pussy.

“You are Dream Searcher,” the voice went on. “You love having kinky sex especially with all your hypno slaves and your best friend Bass Canon,” In front of her eyes the yellow mare was getting down with several ponies both mares and stallions as well as a white and purple unicorn, who must have been Bass. How had she known that? The white unicorn was standing out to her for some reason, as if Rainbow needed to know who she was.

The pleasure kept growing, her body bucking and thrusting as if there was some kind of invisible dong there, just something for her to grind against.

“Yes that’s it let the memories flow into you,” The voice went on as now waves upon waves of memories and feeling flowed into Rainbow’s mind and the bliss skyrocketed. The mare’s mind was losing it, completely lost to the pleasure.

“No we don’t need any of those pesky other memories, now do we?” the voice went on. Soon other memories, those of a blue pegasus running around the sky, hanging out with friends, mentoring a little orange filly. They all started to crumble and fade. The memories of happy day in the park, her friends, even that little filly growing fainter and fainter, the idea of a blue pegasus being nothing more than a fantasy, replaced by images of a yellow mare stand tall, dominating her mind.

As soon as the memories were gone, the bliss the suit was giving out went even higher, as the mare bucked and kicked and finally released, the orgasm washing over her and her utterly rattled mind. She loved the feeling, it was the greatest sensation ever as she calmed herself down.

“Now,” the voice went on, “Who are you?”

“Dream Searcher,” The same voice echoed in her head, this time it was her own thoughts. A wave of bliss passed over her.

“Very good,” the voice went on. “What do you do? What do you want to do? Who is your friend?”

“I am a hypnotherapist, I want to hypnotize everyone and make them kneel before me as well as have lots of sexy hypno sex. Bass Canon is my best friend.” Dream went on.

“Very very good!” The voice gave her another shot of bliss. “One last question now. Who is Rainbow Dash?”

“Who?” Dream Searcher asked, having no idea who that was.

“Exactly,” the voice replied and the last hit of bliss came over Dream Searcher. “Looks like you’re all ready.”

Twilight also was lost in the darkness, but in contrast to Dash, she did not hear a voice, but rather saw a white unicorn in a similar dress, smiling evilly at her.

“Who, who are you?!” she yelled, yet the mare simply placed her gloved finger on her mouth, making Twilight silent, which both was scary and bizarre for the purple mare.

The unicorn began to dance, and moved in to give a lap dance to the trapped Twilight. It was odd, she hand never felt such a heat in her life, the way the mare was grinding, using her tail to whip Twilight’s face was all making it very hard to concentrate on keeping her cool or composure.

“Why are you doing this?” Twilight asked again, this time more of a plea than demand, as she began to hear faint sounds of music, as she saw that the mare was talking, but she could not hear her.

The beat, it was beginning to coincide with the touches this white unicorn was giving Twilight, and it was so easy to sway her head to it, yet Twilight tried to persevere. She had to fight, both this music that grew louder and Luna’s wild magic.

The restraints began to loosen, as the mare rose from Twilight’s lap, making her desire the touch and by instinct rise towards her, breaking the steel clasps as if they never were there.

“... dance with me Twilight.” she heard the whisper, as the music rose in sound, and the click of their boots did as well.

Twilight was torn between her desire to fight and try and save Dash, or to give in to the beat, as this mystery mare proved to hot to handle.

She forced Twilight's hand on her hips, and made the pair sway in unison, as her voice began to not only sound clear, but echo deep into Twilight.

“The name is Bass Canon dear, and I am here to make sure you dance all your fears away.” Bass said calmly in her raspy voice, smacking her own ass with Twilight’s hand, making them both moan in unison.

“What… what just happened?” Twilight asked, slowly mimicking Bass in the movements, unaware of the corruption spreading as they made more and more intertwined moves, their hips, legs and rest of body rubbing against each other.

“You felt the electricity of being pure chaos, that is what. Felt good, I know, and I know for a fact you are desperate to feel it again.” Bass continued, slapping her thigh this time, making the pair moan anew.

Twilight felt this shock deeper than the last one, and worse yet, wanted another one.

“Go on, grab the initiative Twilight, or are you afraid?” Bass teased, to which Twilight growled, scaring herself more than anything. Yet the obvious attempt at provoking her worked so well, and she grabbed Bass from behind, both thighs this time.

“There you go.” Bass commented with a chuckle.

“Don’t tell me what to do, you freak.” Twilight growled again, angry at the fact Bass was not afraid of her for some reason.

“Feisty, where did that come from? Careful now, your voice is getting a bit raspy.” Bass chuckled again and turned towards Twilight, as the beat began to coincide with Twilight's heartbeat.

“Shut up.” Twilight cut her off and pushed her down, as a bed rose to catch Bass.

Quickly recovering, Bass made sure Twilight could see her gleaming ass, the latex making sure the roundness and firmness of it was on full display. The sight of it gave Twilight chills. Never before did she desire an ass so much, and she did not care how to get it.

Slowly the color from her face began to lose it’s purple sheen. She was becoming as white as Bass, the purple seeming to squeeze out of her and forming a thick rubber dildo strapon.

“That’s it dear, make sure to get every last drop of Twi-ah!” Bass wanted to tease but the thick rubber dong pushing deep into her made those plans impossible.

“As I said, shut up and take this dick. I am no idiot Bass, I understand now what I must do to achieve my goals. I don’t mind being you, in fact, as these lovely scenes flood my mind, I begin to see Luna’s plan as not my ending, but our new beginning. Just don’t think Twilight Sparkle is going out without a bang.” Twilight explained, her own inner demon slowly taking hold.

“Excellent, then please do continue Miss Bass Canon.” Bass smiled and spread her legs out more, so as to take the dick better.

“Of course Miss Bass Canon.” Twilight replied, in the last moment she even looked like her old self, all of her heroic personality and identity now inside the purple dildo that was sliding in and out at a pace that gave both mares pleasure.

The pace quickened, as Twilight began to not only resemble Bass in body but in mind too. Memories of Dream, of being a kink engineer, a mare who developed new ways to have pleasure, of her constant battles with her friend and how many funny and kinky adventures they had, all began to feel like reality to her, and the name Bass Canon only became that sweeter to take, to own and enjoy.

The pair were close to the edge, and Twilight felt her last memory seep into the dick, as it released into the old Bass, as the world turned to pure white.

Bass woke up in the bed alone, there was on old self, no dildo or music. Just Bass, as always, in her own subspace.

“I guess it is time to wake up…” she chuckled, as her subspace slowly faded away...

Meanwhile in the real world a mechanical arm descended, a collar in it’s hand. The collar wrapped around Dream’s neck and clicked into place. The mare came to in the real world. The bar around her arms and legs were removed.

Bass’ restraints also were removed, as Luna came back, very much admiring her newest creations.

“Hello girls.”

“Mistress Luna.” the pair replied in unison, the grins matching that of Luna.

“Tell me, who are you?” Luna said already knowing the answer, her smile growing ever bigger.

“I am Dream Searcher,” Dream Searcher said, standing and stretching from her chair. “Who did you think I was?” She smirked.

“And I am Bass Canon” The mare next to Dream said, also standing and stretching.

The sound of rubber latex squeaking filled the room as the two newly made mares tested out their new bodies.

“You like what you see Mistress?” Bass teased Luna who nodded but walked away.

“Oh I do, dear, I do, but you two have work to do.” Luna said as she teleported the two mares into their new apartment in Manehatten.

Luna walked into Celestia’s office, who was looking at the new pilot episode.

“So what do you think?”

“It is provocative, I’ll give it that. And I have never seen anyone as flexible as those two.” Celestia said, her hands under her muzzle.

“And the ratings?” Luna asked, very much eager to hear.

“Doing great. Not beating “Game of Thrones” anytime soon, but the ship is sailing okay. Equestria is saved, by my lunatic sister and too much lube. Oh, I am going to have to drink this day away at some point.”

“Huzzah!” Luna exclaimed, her rubber suit squeaking as she clenched her fist.

“Must you wear that everywhere now?” Celestia groaned, the long day taking its toll.

“... It makes me feel pretty.” Luna admitted shyly.

“Ugh fine. We still need a male character as well, to balance the demographic.” Celestia explained, looking at the ratings and pointing at the distinct drop in one of the focus groups.

“Oh don’t worry, I just phoned him in.”

Meanwhile deep in the basement of Canterlot.

“Hello,” the timid little yellow pegasus rang out. “Is anyone here? I got a desperate message from Princess Luna.” Fluttershy said as she wandered the dark, barely lit hall.

A door opened up in front of her, pouring out light compared to the halls

“Fluttershy, come in quickly, there is little time to lose!” Princess Luna said emerging from the door.

As Fluttershy hurried past her into the sparingly decorated room, she failed to notice the smirk on Princess Luna’s face.
