Another night begins, and thus does another night of being locked up by Nightmare Moon. You remain quiet as the latex suit goes on, followed by the straitjacket. You don't resist as your arms are magically placed into the sleeves, which are then secured around your tummy and locked down tight. You don't wince as the Princess of the Night yanks the straps around your butt and secures them, and with well-practiced grace, you open your mouth and endure the giant muzzle that enters and ensures your silence. The posture collar comes next, and finally, thick iron shackles that lock around your ankles.
“There, slave!” Nightmare Moon proclaims. “So begins another night of your imprisonment! Wander if you will! Seek an exit if you will! But know that you will never leave my palace!”
Blah, blah, blah you think. Still, you close your eyes and bow. Have to give the ruler of Equestria her proper respect. Once that's done, you play the part expected of you. To wander throughout the palace of the Princess, shuffling through abandoned halls and dusty rooms. Some would call you a living ghost, trapped forever in this crumbling castle. And in a way, they'd be right.
But none of them would know that you've got a trick up your sleeve, one that Nightmare Moon remains unaware of. And tonight, you will finally bring her down.
*
When Nightmare Moon defeated the Bearers and her sister so many years ago, the ponies of Equestria quickly realized that with eternal night would come famine and eventual extinction. In Celestia's name, all rose against Nightmare Moon, but she was too powerful. Even though you had only lived in Equestria for a short time, you had grown so fond of the ponies that you immediately enlisted to help the war effort. Nobody really knew what a human could do against Nightmare Moon, but they welcomed your help anyway. You even participated in the most daring raid ever attempted: a siege of the Princess' castle, with a force of almost a million soldiers. Dressed in your battle armor and wielding your magical sword, you were among the few who managed to get past the defenses and fought their way into the throne room.
There, face to face with Nightmare Moon, you bravely raised your sword and charged, adrenaline flowing through your system. It was you vs. the most powerful and most dangerous pony in all of Equestria.
Needless to say, you lost.
The siege was a disaster. The forces of good were routed and forced to flee. The unlucky ones left behind were taken prisoner, including yourself. As was Nightmare Moon's way, all the captured ponies were sent to the moon, doomed to be imprisoned within it forever. But Nightmare Moon paused when she reached you. Having never met a human before that night, she gave you a special fate: You would become her personal plaything.
It was hard to learn that you would spend the rest of your life a slave and plaything of Nightmare Moon. The first few months were brutal. Nightmare Moon, it turned out, delighted in restraining her captives. You'd be left in a cell all day with your arms shackled to the ceiling. Other times, she'd strap you to a chair, blind and gag you, then say she was going to let others have their way with you. You'd be left in complete darkness, left wondering just what she had in mind. She’d even go for simple tricks and lock you in a coffin and leave you there for what felt like days.
As time went on, she refined her method and experimented with all sorts of restraints before deciding that the straitjacket was her favorite toy. Thus, you were routinely locked inside it every day, with her magic ensuring that your arms wouldn't suffer any ill effects. Once, when you snapped and yelled at her, she punished you by locking the jacket onto you for an entire year while you were in the dungeons. But even then, that wasn't enough. She began to add cuffs, straps, gags, blindfolds, and even hoods onto you. Then she got tired of seeing you naked, and forced you to wear skin-tight latex at all times (black, of course, to remind her of her own beautiful coat).
Eventually, she came across the perfect scenario for toying with you. She would give you the illusion of freedom while you were still locked up. Thus, each evening, you were restrained, but allowed to walk and wander through the castle as you wished. But with the drawbridge always retracted, escaping the castle itself was impossible.
This was your fate: to spend the rest of your days locked up as Nightmare Moon’s helpless plaything.
At least, that's what she thought.
*
When your involuntary service to the Princess began, you nearly gave in to despair, as anyone would. That wasn’t from the restraints, for you’re the type who doesn’t mind wearing them. What was hard was realizing that all control had been taken from you without your consent. Depression nearly claimed you as you sat in the dungeons for that long year, sealed in a tiny cell with nothing but your thoughts for company. But it was in those dark depths that you realized something: For all that she had taken from you, there was one thing Nightmare Moon could never claim: your mind. She could lock your body up, but she couldn't lock away your thoughts and attitude.
With that realization, you decided to give yourself a goal, and something to work towards. Escaping would be the logical choice, but another option beckoned. All attempts to defeat Nightmare Moon by force had failed, but nobody had tried to defeat her via subterfuge and espionage. And as the only other permanent inhabitant of the castle, you were in a unique position. The Princess was proud, arrogant, and believed herself so superior to everyone else that she refused any help in running the land. But what if her only slave began to get close to her? What if, by remote chance, a relationship blossomed between the two of you? What if you began to forge a bond with her? When her guard was relaxed and at its lowest, perhaps she would listen to your suggestions (worded in such a way as to praise and worship her, of course).
Maybe you could bring her down from within.
When the Princess unlocked your cell door a year after sealing it, you emerged with the appearance of someone humbled and tamed. But a fierce fire now burned deep within.
Nightmare Moon didn't know it, but her reign was officially doomed.
*
You make your way up the stairs to the top of the tallest tower, taking great care not to rush. With your arms restrained, you'd have no way of stopping yourself if you tripped and fell. You finally reach the peak of the tower and enter the Princess' throne room. She sits upon it, gazing out to the land beyond the castle.
“Oh, what's this? My slave has come to beg and grovel before me! Kneel!”
You do so.
“I will allow you to speak, but you will not be permitted to gaze upon my glorious beauty!”
A blindfold magically wraps itself around your eyes, sealing you in darkness. Moon's magic undoes the straps on your muzzle, yanking it from your mouth. You take a moment to get your tongue wet before speaking, hoping that this will work.
“Nightmare Moon... I'm tired of my life. I'm tired of all this. I-”
“You wish for death to release you? I forbid it! You still have many more decades of service before you.”
“I accept that,” you say, doing your best to remain humble. “But I want something better. I want to improve my life. I want it to have meaning and purpose. I don't care what it is, only that you allow me to do so.”
The silence is absolute. Nightmare Moon’s never been this quiet before.
You sweat, your heart pounding. If this doesn't work...
“Report to your cell. You shall spend the next three days there while I consider your request, slave.”
The muzzle is locked back into place, the built-in gag pushing itself deep into your mouth once again as the blindfold is removed. You nod to your princess, and then make your way into the castle’s dungeons and enter your tiny cell, sitting on the bench as the door magically closes and locks itself. You settle in. Staying locked up itself isn’t going to be hard, but not knowing what’s going to happen will test your nerves.
With no light aside from the flickering of torches, you don't know how long you remain in you cell, squirming occasionally within your jacket, and shifting to try and smooth out some of the pinches in the latex. Eventually the cell door opens, a faint blue mist guiding you back up to the throne room. The Princess awaits upon her throne, looking most pleased with herself.
“I have considered your request, slave, and have decided to grant it. You shall no longer be just a toy, but my personal servant who shall obey and fulfill my every whim. Do well, and you shall be rewarded. Fail, or dare to strike me, and the jacket will be sealed on you for the rest of your days! Do you understand?”
You nod.
“Very well, then! Your service begins now!”
Her magic shoots over you. While the straps securing the jacket remain in place, the sleeves are loosened, and fingers appearing in the fabric, allowing you to use your hands.
“I have been so busy ensuring the well-being of my ponies that I have not yet washed myself today. You shall wash and clean your Princess! Prepare my bath!”
You nod and head towards the royal bathroom.
“No, not that bath! You shall clean me by hand!”
For the next hour you go about your task of preparing Nightmare Moon's bathwater, making sure it's nice and hot before mixing in the soaps and luxury oils, hoping she finds the combination wonderful. When the water is done, you bring the buckets to her throne room, take a sponge, and wash her. It's a lengthy process, as you have to go over every inch of her body, pressing the sponge hard against her skin to clean away the dirt and assorted oils. It isn't long before your arms are sore, but you don't dare say a word, doing your best to keep your strokes smooth and focused, like those two ponies in Ponyville's spa... it almost feels like it was a lifetime ago that they were treating you to a luxurious massage-
“Focus, slave!”
You turn your attention back to the matter at hand. While you're used to the straitjacket, you have no desire to have it permanently fashioned to you, as erotic as it may sound.
When the bath is finally done two hours later, Nightmare Moon's body sparkles beneath the moonlight. She looks herself over. “I am pleased, slave. You have done well!” She fluffs her mane. “Your services are no longer required. Return to your cell!”
Nodding, you head down the stairs to the dungeons, wiping the sweat from your brow... that is, until blue magic takes hold of your arms and threads them through the straps, once again locking them across your chest.
*
You continue to clean Nightmare Moon every night for the next several months, in addition to all the other tasks she gives to you, including tidying her room, sweeping the castle, and generally acting as a housekeeper and personal servant. At times it's humiliating and degrading, but you manage to keep silent. You're biding your time until the moment is right. And in doing all your tasks faithfully, and appearing to even gain pleasure from fulfilling them, you're slowly building up a relationship with your captor, working to earn her trust. With any luck, it won't be long until she takes the next step.
That moment comes one night in the summer while you're dusting the castle's library. Nightmare Moon looks out the window to the fields. She seems puzzled.
“What is the matter, Mistress?” You ask.
“It is the fields, slave! My little ponies toil endlessly, yet they cannot grow food! If something is not done, they will starve!”
This is it. Your moment to strike.
“That is because food cannot grow without sunshine, Mistress.”
“I am aware of that!” Nightmare Moon thunders.
You wince, gulp, and continue on, but in a respectful tone. “If I may offer a solution, Mistress? Perhaps you may raise the sun temporarily each day, for no longer than an hour. That may give the soil and seeds enough light to which to grow, after which you may raise the moon once more.”
Nightmare Moon is silent. Then she nods. “Your suggestion is logical, slave. I shall do this!” She thrusts herself forward. “Attention my subjects!” she shouts, her voice booming across the land. “All farmers are to report to the field, for I shall raise the sun so you may all grow food! Go now and use your magic to make the plants grow!”
Her horn glows, and the moon, which hasn’t moved in over two years, drops below the horizon. In its place, the sun rises. You have to turn away, the light being so bright it hurts your eyes. But when you can finally stand it, you walk to the window and look towards the sun. It's so warm and beautiful, and the land beyond the castle... it looks so alive. You can just faintly see the outlines of ponies in the fields beyond the Everfree Forest, rushing to make the most of the time they've been granted.
“Is this pleasing to you, slave?”
You shake your head, having forgotten that you were standing next to Nightmare Moon. “Yes, Mistress. It is.”
“And why is that?”
You choose your words carefully. “Because you have been merciful, and allow the ponies the chance to grow their food.”
Any other villain would see through your sweet talk. But Nightmare Moon's pride is boundless. “Indeed, I am! And I am most merciful to those who serve me!”
Her horn lights up, and your arms are suddenly locked back into place.
“You inspired me, slave, and you shall be rewarded! Enjoy the gift that your princess now gives you!”
A rush of energy hits your groin. Before you can even take a breath, a warm, wonderful sensation spreads through you as a wave of pleasure begins to build, growing bigger and bigger with each second. It's so all-consuming that you fall to your knees, gasping even as you grin as the sensation reaches its peak, washing over you so much that you fall and moan in sheer ecstasy. Then, almost as soon as it came, the pleasure fades away, and you're left on the floor, breathing deeply and feeling more satisfied than you can ever recall.
All that pleasure... it felt so good.
A chuckle makes you look up. Nightmare Moon obviously enjoyed the show. “Continue to serve me well, and more rewards like these shall be given to you!”
Needless to say, you throw yourself into your work with newfound abandon. Mostly due to the fact that you've established a connection, and need to work to ensure that it'll continue dot strengthen. But you're also working for more of that incredible pleasure, of course. Who could resist it?
*
The next several months go by in a blur. You continue to offer suggestions to Nightmare Moon when the opportunity presents itself, not wanting to give the impression of being pushy or frantic to get another pleasure wave... though you do get those from time to time, each one longer and more powerful than the last.
Nightmare Moon gives you other rewards as well. She upgrades your latex suit from black to a shiny silver that glistens under the light of the moon and the castle's candles. A few months after that, she rewards you for your hard work with a brand new jacket. No longer do you have a wear a generic one of heavy-duty cotton, for now you have one built from high-quality black leather, the inside lined with luxurious sheepskin that glides across you when you're locked into its embrace. Nightmare Moon was most pleased as you wiggled in it, luxuriating the tight, form-fitting softness.
While technically still a prisoner, you're being treated like luxury.
A year passes. Crops continue to come in. Your whispered suggestions cause Nightmare Moon to concede other things as well: Ponies are now free to travel where they want instead of being confined to their towns. Then those towns start to govern their own affairs. Then they elect their own rulers.
Bit by bit, you keep whispering into Nightmare Moon's ear. Against all odds, her popularity grows. Other ponies begin to think she's coming to her senses. Nightmare Moon doesn't see it that way, believing it to be all her own doing. You remain silent, letting her think that.
Five years after you were taken captive by Nightmare Moon, your goal is finally accomplished. Nightmare Moon, after giving everything careful consideration, has finally decided that the sun shall once again raise regularly over Equestria, restoring the day and night cycle once more. And no longer will she rule over ponies with an iron hoof, but with compassion, understanding, and gentleness. After all, it is the Equestrian way.
For you, the day is a glorious one. You're used to watching the sun be up for an hour at a time, but now it will be up twelve hours a day. And it's all thanks to you. Best of all, Nightmare Moon has no idea that it was you who slowly turned her. Not from persuasion or threats, but kindness and compassion, slowly reforming her, helping her see that doing good feels good. Even if you are to remain in this castle for the rest of your life, at least you know you have helped to free a nation.
Hooves clank against stone as someone enters the throne room. You turn as Nightmare Moon enters, and you kneel.
“Rise.” As you do so, Nightmare Moon comes over. “Slave, I have come to realize that no longer must I rule over my ponies like a tyrant of old. For now they have both the sun and the night to enjoy, and they delight in my night as I once hoped that they would...but...”
“Yes?” you ask. “Is something wrong?”
Nightmare Moon nods. “It is strange, but I feel... guilty.”
“Guilty?”
“When I look back, I realize that my sister, Celestia, was right about me. The ponies did love my night, even though I could not see it. I allowed my pride to consume me, and I brought about misery for my ponies! I must make amends!” She quiets herself. “I have come to rely on you not only as my slave and servant, but as my counselor, and now I ask you this: What must I do to atone for my crimes?”
It takes you a good minute to come up with an answer. “If you wish to atone for all you've done, then you must undo the damage you caused. You have restored the land and given the ponies their freedom, but you must release all the prisoners you took. And if you wish to fully atone, you must also restore Princess Celestia.”
“Celestia?! But she will put me in the moon once again for another thousand years!”
“Not if she sees that you have changed, and not if she sees that you are trying to atone for what you did.”
Nightmare Moon considers your words. “You are indeed wise, slave. I shall release the prisoners from the moon immediately. But I cannot give back what I took from them... therefore, it is only fitting that I be punished for putting them there!”
Her magic comes to life, and your jacket is removed. A moment later, and Nightmare Moon fires her magic high into the sky, where it slams into the moon.
“It is done. The captives have been released, and will soon return. But they shall sleep for a day. Enough time for our task to be completed. Now come!”
*
The two of you head deep below the palace, level after level, until you arrive on the lowest, where the strongest cells are kept. Despite the security of this place, you're the only one to ever come down here, as you've slept in the same cell every night. Nightmare Moon herself has only come down here twice, once to lock you in your cell, and the other to release you a year later. She now walks in silence, until arriving at a cell in the most remote corner of the dungeon.
“Slave, go to the storage room.” A key magically appears in your hand. “Take all the restraints you find and bring them to me!”
It's strange fulfilling her order, and upon unlocking the room you find all manner of restraints, locks, and everything needed to tie up a prisoner. You recognize most of them, for they were used on you many times. It takes three wheelbarrow trips to take all the equipment back to Nightmare Moon, and on the last one she finishes a scroll and magically teleports it away.
“That letter will explain to my sister what is happening. By the time she arrives, she will be too late to undo what has been done!” She examines the pile of restraints before her. “Slave, this is your last order: I command you to restrain me, upon which I shall seal myself inside this cell!”
“What?”
“It is only just that I endure what I did to my captives, to the Bearers, and to Celestia. Therefore, I shall remain here for fifteen years: Five for the captives, five for the bearers, and five for my sister! Only then, when I emerge, will my soul be cleansed!”
Raising her hooves, Nightmare Moon removes her horseshoes, then her collar, and finally, her helm and crown, leaving her without any adornments. “Now, slave, fulfill your final duty!” She closes her eyes. “Restrain me as I once restrained you!”
It's the most bizarre command you've ever been given, but you proceed. For the next hour you clean Nightmare Moon, and then put her inside a white latex bodysuit. Then, for a bit of dramatic irony, you lock her into a straitjacket, taking care to make the process slow, unable to resist making her feel helpless as her front legs are pulled into the sleeves, then threaded through hoops and straps before being buckled down and locked into place. To her credit, Nightmare Moon keeps her eyes closed and her head held high, not resisting as you slowly take her freedom away bit by bit.
Manuevering Nightmare Moon with your hands, you guide her into the cell, at which point you then lock her rear legs into a sleeve, which you then lock to the straitjacket. Only her head remains uncovered. You wrap a posture collar around her throat, buckling it down tight. It'll be attached to the wall soon enough, but you're not done yet. A blindfold is latched tightly around Nightmare Moon's head, sealing her eyes shut and ensuring that she will see nothing but darkness for the next fifteen years. Then a tight hood, one that hugs every inch of her head so that there are no wrinkles or folds in the fabric. Only then do you take the various chains and attach the jacket and sleeve to the rings embedded in the walls. Locks go on, and Nightmare Moon is officially locked into her cell.
All that remains is to silence her and seal the cell.
You take a thick muzzle and bring it to Nightmare Moon's mouth. “Do you have any last words?”
“Yes. You have been a good slave to me, and have served faithfully for many years. Therefore, I will give you one final reward for being in my service.”
“My freedom?”
Nightmare Moon gives a smug smile. “No. Quite the opposite, in fact.”
A whoosh, and your straitjacket quickly embraces your body. Your arms are thrust through the hoops before you can even gasp.
“What are you doing?!” you cry out as the straps and buckles are fastened down tight.
A cell door across the hall opens.
“While I shall spend the next fifteen years within these cells, I shall not be alone,” Nightmare Moon says. “You will join me.”
“No! You ca-”
Your voice is cut off as your muzzle falls into place, the straps wrapping around your head.
“Do not be afraid, slave, for you have earned this.”
“Mphrmph!” you cry out, trying to form words as Nightmare Moon's magic drags you into your cell. Chains attach themselves to you, securing you to the wall as cuffs lock themselves around your ankles before they too, are secured. You thrash and fight, but it's no good. You can't break free.
The ceiling rumbles.
“Even as we speak, the dungeons are being sealed. My most powerful magic will ensure that not even Celestia will find this place until my sentence is complete.”
More bangs as tons of stone are shuffled about and fall into place.
“This is our tomb, slave. We shall remain here, together, for the next fifteen years. But be not afraid. My magic will keep you alive and safe.” Nightmare Moon smiles. “You shall find your imprisonment a most... enjoyable experience.”
Nightmare Moon's muzzle levitates, and she accepts it into her mouth, strapping it in with her magic. And once that's done, the door to her cell slowly swings shut, allowing you to watch as she's embraced by darkness before the door slams shut, internal locks falling into place and sealing her inside.
As soon as her cell is secured, the door to yours swings shut. You scream as darkness embraces you, and the numerous locks are applied, ensuring that even if you could free yourself from your jacket, you'd never be able to get out.
The banging continues as stone fills the hallway beyond your cell... and then stops.
All is silent.
You breathe deeply, nostrils hissing as you suck in air, trying not to panic. But how can you not? This will be your tomb for the next fifteen years. Locked up, secured, and unable to escape, you will remain in darkness, passing the time until-
Wait. What's that? A feeling within you... a sensation. One of...
...pleasure.
Your frantic breaths stop. The fear goes away as that familiar, oh-so wonderful pleasure goes through you, rising, building faster and faster. You've felt this many times before, but it's just as wonderful now as it's always been, but... wait. Something new is happening. You're... you're... you're going beyond!
You thrash violently within your jacket, the chains barely holding you as you have a mind-blowing orgasm, the ecstasy alone causing you to thrash and fight your restraints, kicking and struggling, your latex suit squeaking, and the straps on your jacket creaking as they're pushed to the limits while you scream into your gag. You expect the feeling to last a few seconds, maybe ten at most.
But it doesn't. It keeps going.
And going.
And going.
And going.
Only after what feels like an hour does the incredible pleasure subside. You collapse to the floor, exhausted, your suit and jacket soaked in sweat. But you're too zoned out to care. This is bliss beyond anything you've ever felt. You're so tired, so worn out that you just want to sleep, to rest and relax.
Then you feel it.
Pleasure.
It's coming back.
*
It's quiet throughout the castle, especially in the sealed dungeons. Nobody could get through the spells and fallen stone that ensures no one will enter for the next fifteen years. As a result, nobody's there to listen to your muffled screams.
Nobody’s there to listen to you receiving your reward for taming Nightmare Moon.
