Your Part

As Twilight watched the Maretonian dignitaries exit the palace, she pondered how much effort Princess Celestia could have saved had she simply magicked an illusion of Twilight to appear instead.

Though Twilight knew her role was small, she’d hoped she could’ve played some larger part regardless. Maybe caught the Maretonians’ attention with her knowledge of their tax system or bodies of government. Anything she could’ve learned something about, or been useful for. But all they’d done was thank her for keeping herself out of their confidential discussions. Twilight didn’t want to admit it, but it hurt a little.

Was she not important enough to know? Was all she was good for as Equestria’s newest princess the royal equivalent of scrubbing dishes at The Hay Burger?

Hiding her frustration as best she could, she turned to face the other three princesses. “Is there anything else I can do to assist with their visit?”

Cadance looked at her sympathetically. “I'm sorry, Twilight, but their visit is already over.”

“Oh.” Twilight's ears drooped in disappointment.

“Something wrong?” Luna asked.

“I guess I just don't really understand why I'm here.” Twilight let out a heavy sigh. “I get that the princesses have to keep appearances. But it seems like since I’ve become a princess, that’s all I’ve had to do.”

She pointed at the alicorns one at a time. “Princess Celestia and Princess Luna, you raise the sun and moon and run Equestria together. Princess Cadance, you protect the Crystal Empire. But me? There’s nothing new I’ve been able to do since becoming a princess, except… smile and wave.” She turned toward Celestia. “Princess Celestia, you’ve done so much for me, and I am truly grateful. But…” Her eyes looked away. “I don’t know if I really deserve the title of, well, ‘Alicorn Princess.’”

Celestia approached Twilight and touched a light hoof to her chest. “Trust in yourself, Twilight. Your time will come.”

“But isn’t there anything else I can help with?” Twilight asked. “Paperwork that needs filling? Meetings that need attending? Even if it’s just a little bit.”

Luna chuckled. “Nay, Twilight. We can handle our own administrative tasks just fine. You require no ‘princesshood internship’ to take your place among us. All you need is time.”

Twilight groaned. Though she tried to ignore the thought, some part of her told her she was useless, just an auxiliary backup princess in case the real princesses needed saving.

“Sometimes, I wish I was just your student again,” she mumbled. “At least then I knew what I was meant to do.”

Celestia wrapped her foreleg around Twilight and drew her into a reluctant hug. “It is difficult charting one’s own path, yes. But when I sent you to Ponyville those many moons ago, I had every faith you would find your way, and that faith has never waned.”

Twilight looked up at Celestia with pleading eyes. “And I’m sincerely thankful, Princess.” She gave a short laugh. “And I guess you knew from the start. You, heh, didn’t tell me, but you knew.”

And there she was, Twilight Sparkle, newest Princess of Equestria. Yet, she felt like a newborn foal, even more clueless than the Cutie Mark Crusaders.

She hesitated to say it, but the words came spilling out of her mouth. “Is all this uncertainty and me feeling useless part of your plan too, Princess? Or am I just being primed for something else I don’t know about yet?”

Her cheeks burned. It felt so wrong questioning her role model, her mentor, but she needed to know. She squeezed her eyes shut, waiting for Celestia to berate her, maybe even say she made a mistake and that Twilight never should’ve become an alicorn.

Instead, nothing happened for a few silent moments. Celestia gave a long sigh, and she cautiously peeked her eyes open. Celestia was smiling softly.

“Well, alright,” said Celestia. She chewed her lip. “I suppose there is one thing I’ve been keeping from you. I’d been meaning to tell you later, but now is as good a time as any.”

Twilight watched raptly as Celestia looked around, as if observing her surroundings, before turning around to face Luna and Cadance. Celestia muttered a few phrases Twilight was just barely able to make out—”Sleepy Luna. Crystal haze.” Confusion clouded Twilight’s face as she watched their faces and bodies briefly slump before straightening, before they began walking around Twilight.

“Luna? Cadance? Celestia? W-what’s going on?” stammered Twilight. All of a sudden, her fur was tingling.

“Hush now, Twilight,” Celestia soothed, her hoof lifting the younger mare's head with gentle grace. “Close your eyes and trust in your teacher once more.” Though phrased kindly, it was clearly an order.

“O-okay, Princess.” Twilight swallowed hard but did as she was told. She took a deep breath, willing herself to trust Celestia once again. Heart beating rapidly, she bit her tongue as she heard Celestia’s magic activate.

After a moment, Celestia said, “You may open your eyes, my faithful student.”

So, Twilight opened them. “Princ- huh- wha-”

Celestia’s eyes were glowing, shifting. A mesmerizing kaleidoscope of color dragged Twilight’s attention in, and her breath caught in her throat as she gazed into the never-ending abyss of iridescent golds, bright whites, vibrant reds, lurid greens. With every pulse and glow, she found her head dragged toward their lapping swirls, thoughts and feelings evaporating, replaced with an inner calm.

It was hard for Twilight to tell where the spirals began and ended. With every passing moment, they only drew her deeper. Lose yourself in me, they seemed to say, and Twilight did.

Eyes heavy.

Thoughts slow. No thoughts when looking at the spiral.

“That’s right, Twilight,” said Celestia. “Focus on my voice, Twilight. Just keep looking into my eyes and sinking deeper, deeper.”

Had Twilight been looking at her reflection, she’d see Celestia channeling golden magic deep into her mind, casting a yellow glow over the spirals forming within her own eyes. She’d see her jaw slack, head barely nodding, almost as if drifting off to sleep.

She felt relaxed, so relaxed.

And yet, some last vestige of her knew something was wrong. Like a cornered dog, it clawed itself to the forefront of her mind.

“Ngh- no, this. Princess, what are you-” It was so hard vocalizing her thoughts. “This is-”

Before Twilight could finish her sentence, Celestia's voice cut in, her tone calm, but unwavering. "It is necessary, Twilight. You must trust me and let go of your doubts."

Trust Celestia. Let go of doubts.

Doubts.

“N-no!” It was so hard looking away from the beautiful spirals, but some small part of her forced her to try. “Luna… Cadance… help…”

Desperation welled up within her when she realized they were just standing there, as if completely oblivious to her plight. Their expressions remained neutral as they simply observed, eyes almost staring through Twilight.

She needed help. Why weren’t they helping her?

“You d-did something t-to them…” she sputtered. “How could…”

Celestia pressed a hoof to Twilight’s lips. Even with just the touch, Twilight gasped in pleasure. It sent tingles through her head, as she found herself lost in the sea of Celestia’s closer gaze.

“Trust in me, Twilight. You’ll understand soon, just as they have. Isn’t that right, sister, Cadance?”

"Yes, your highness," they chanted in unison, their voices devoid of any inflection or emotion.

“Very good. And shouldn’t Twilight be good and listen too?”

“Yes, your highness.”

Celestia smiled and nodded, causing Twilight to nod along, following Celestia’s eyes. “Your fellow princesses are waiting for you, Twilight,” she said. “All you need to do is… submit.”

Immediately, the swirling colors in Celestia’s eyes seemed to take on even more of a life of their own, dancing and twirling in intricate patterns that drew Twilight in deeper and deeper. The colors shifted from gold to orange to pink and back again, each shade more vibrant and alluring than the last.

Twilight sunk into the hypnotic rhythm of Celestia’s gaze. It surrounded her like a warm, comforting blanket, her thoughts and worries threatening to fall away until there was nothing left.

And yet, the cornered dog lashed out even harder.

“Y-you’re not Celestia…” she panted. “You’re an imposter, a t-traitor…”

“Twilight.” Celestia looked at her with disappointment. “You wound me. Do you not recognize your mentor, the one that has guided you all these years?”

“Then P-Princess, w-what are you doing? This isn’t like you at all!” Twilight struggled to tear her gaze away, but turning her neck felt like moving concrete.

Celestia’s voice was calm and measured. “My faithful student, you must trust that I know what is best for my little ponies. I have always guided you to the light, have I not? All you must do to know is look into my eyes.”

Celestia’s magic flared more intensely than before, and Twilight felt magic pressure applied deep within her mind. With a gasp, Twilight found herself held even deeper within Celestia’s thrall, and time seemed to stand still as all she could do was look.

“My dear Twilight, do you not wish to learn from me again as you did in your youth?” asked Celestia. “Let me help you fulfill your wish. Feel yourself focus. Open your mind. Feel yourself take deep breaths now, in and out.”

In and out. In and out.

Twilight’s breathing slowed and her muscles relaxed.

As Celestia softly began stroking Twilight's mane, she purred in her ear, "Doesn't that feel nice?"

“N-ngh…” Twilight could do little more than moan, even though she knew it was wrong.

“That’s right.” Celestia smiled. “Just feel your worries and doubts melt away.”

In and out. In and out.

So calm. So relaxed.

“You’re doing so well, my faithful student. Letting yourself accept my every word, knowing just what I need you to do.”

Accept Celestia. Follow Celestia.

“A lullaby to soothe your troubled mind, my little pony,” said Celestia. She briefly turned and beckoned for the other princesses to approach, before beginning with a gentle lilt.

Your destiny's uncertain
And that's sometimes hard to take
But it will become much clearer
With every new choice I make

Luna continued the verse, her voice soft and melodious, blending seamlessly with Celestia's.

Patience is never easy
I understand wanting more
But you must show obedience
To spread out your wings and soar

Cadance joined in, her voice clear and sweet as she took up the next verse.

You stand here for a reason
My voice is as soothing as it’s strong
That crown is upon your head because
You will belong

Their voices washed over Twilight, stirring something deep within her mind. A warmth spread through her body with each note, loosening her thoughts and relaxing her will.

Together, the princesses harmonized, their voices blending in a beautiful chorus.

Know that your thoughts are drifting soon
As the sun rises, so fades the moon
As love finds a place in your heart
You are a princess; obey your part

Luna brushed a hoof against Twilight’s cheek before continuing.

Don’t you feel yourself wanting more
A chance to surrender, a chance to soar

With Luna’s touch, Twilight felt her eyes become unfocused. Her view blurred and faded as the lullaby fogged her mind.

Cadance lovingly put a wing around Twilight’s back and took up the next verse.

Today is the day it turns around

Finally, the three princesses joined together in one final verse.

Know that your thoughts are drifting soon
As the sun rises, so fades the moon
As love finds a place in your heart
You are a princess; obey your part

The words sunk into Twilight like stones in a tranquil pond. She struggled to keep her eyes open, desperate to embrace sleep, the hypnotic spirals the only thing keeping her afloat.

“Your time will come,” murmured Celestia. “Follow my words, and feel bliss in your obedience.”

“Obey your princess, Twilight,” Luna said.

“Obey your princess,” Cadance parroted.

In Twilight’s scattered mind, the words of her trusted mentor and friends made sense. Her mouth moved almost of its own accord. “O-ob-ob-b…” But still, some last part of her resisted.

“Take your time, Twilight,” said Celestia. “Let the words bounce around in your mind. Let them absorb into you, into your being. Let every word make you even more tranquil, at peace. Can you do that for me, Twilight?”

Twilight only sighed in response, her head bobbing in time with the spirals. Thoughts of giving in echoed deep within her, making her feel even more calm.

“It feels good following my words,” said Celestia. “It feels good letting all that stress disappear. So much better letting me do the thinking.”

Twilight tried forming her own thoughts and found she could not. Obeying her princess and letting Celestia take control of her thoughts felt comforting, safe.

Celestia cupped Twilight’s chin in her hoof and leaned in even closer. “Now try again, Twilight,” she whispered, her breath hot on Twilight’s face. “All I need is for you to fall.”

Twilight’s body trembled with conflicting emotions. A part of her wanted to resist, to break free from the hold of her princesses and reclaim control of her own mind. But another part of her longed to surrender completely, to let go of her worries and fears and simply obey.

It felt so nice having Celestia so close, filling her mind with hazy pleasure. She liked having Celestia’s voice in her head. With the other princesses urging her on amidst her own uncertainty and fear, it felt so much easier just following the long, narrow, welcoming passage of Celestia’s command.

Like a rubber band being pulled in two different directions, she began to feel her resistance let go. For a moment, she remained suspended in this state of tension until finally, with a whimper, her doubts slinked away, and the rubber band could do nothing but hurtle in the opposite direction. Pleasure coursed through her entire body as everything seemed to just click into place, and Twilight squirmed and writhed in bliss. She squeezed her eyes shut, her breath coming in short gasps and her mouth open in a silent moan of ecstasy.

When she opened her eyes again, they were glazed over, thrumming in the same brilliant light as Celestia’s magic.

“Yes, your highness,” she said. “I obey. I am yours to command.”

Celestia smiled, the corners of her eyes crinkling with warmth, and Twilight's heart swelled. She leaned eagerly into Celestia's nuzzle, craving her affection and praise like a parched flower craving rain. "That's my good princess," Celestia purred, and Twilight glowed at the endearment, longing to prove how good she could be.

Celestia turned to face Luna and Cadance, who were both standing at attention now that their jobs were complete. “At ease, princesses,” she said. “I am very proud of the work you’ve done today.”

Immediately, Luna and Cadance softened, wings folding and heads bowing in unison before their ruler. “Thank you, your highness,” they intoned.

For the first time, Twilight noticed that their eyes reflected the same glow her own must have been. Finally, it made her feel like she belonged. They must’ve been so happy welcoming her into Celestia’s thrall.

Celestia turned back to Twilight. “Now, I hope you realize the joy they feel in obedience.” She slowly ambled out onto the balcony, looking at the night sky. “After returning from her banishment, Luna was… troubled. She feared the Nightmare would come and reclaim her. Now, such a thing will never happen again. Isn’t that right, Luna?”

Luna bowed again. “Yes, sister. Thank you for saving me from myself once more.” As if repeating a mantra, she added, “There is no envy or jealousy in obedience.”

Celestia nodded. “Very good. And Cadance’s kingdom was always so distant from my own throne. What if she was kidnapped by Chrysalis again? Or corrupted by Sombra? I needed to make sure they could not get to her mind first.”

Cadance followed suit beside Luna. “My mind and kingdom are yours, Aunt Celestia. Obedience means peace and security.”

“Well put, Cadance. And now, the time has come for me to extend my control to all of Equestria’s princesses. Come, Twilight.” She beckoned for Twilight to approach, waiting upon her slow, mechanical steps. “I hope you understand now why I have kept you in the dark until today.”

Twilight’s newly enthralled mind understood perfectly. She felt only devotion and a wish to serve as Celestia commanded. “Yes, Princess. I understand now.”

“Then,” Celestia said, her expression darkening, “do you understand now why you should not have doubted me?”

Twilight’s gut twisted. She didn’t know why she hadn’t trusted Celestia in the first place. “Yes, your highness. It was wrong of me to resist. Please forgive me.”

“Worry not, my dear Twilight. All is forgiven.” Celestia’s frown faded, and she wrapped a wing around Twilight and pulled her close. “You have always deserved your alicornhood, Twilight Sparkle,” she said. “Your intelligence and ability have always had the potential to rival us all.”

Celestia’s words sent shivers up Twilight’s spine. “Thank you, Princess. I am honored by your praise.”

“But you were too uncertain, too naive,” Celestia continued. “You needed someone to guide you, command you. I hope your new role serves you well.” She allowed herself a wry smile. “My little princess. My little hypnotized puppet princess.”

Twilight almost purred at the title. It felt like a badge of honor, a symbol of her devotion to her mentor. “Please command me as you see fit, Princess.”

“Very well.” Celestia coughed and straightened her posture. She intensified her magic, and when she spoke her voice was once again filled with authority. “Now, Twilight, let my words fill your mind again. Let my thoughts become your thoughts. Let yourself sink deep into relaxation again. Deep breaths, in and out. Good.”

She waited briefly for Twilight to fully settle in before continuing. “Now, in a moment, I will bring you fully into trance. Let yourself accept that. Do you feel sleepy, Twilight?”

“Yessss,” slurred Twilight, her eyelids already drooping.

“What an excellent, compliant princess.” Celestia leaned over and began lightly massaging Twilight’s shoulders. “Then, let me count down for you, and with each number, feel yourself sink even deeper.”

“Five. Any remaining tension beginning to leave your body.”

“Four. Even calmer than before, ready to fall deeper into trance.”

“Three. Feeling yourself enveloped by my words, each word making you sleepy.”

“Two. Ready to pull a blanket over yourself and just float away.”

“One. So close you can feel it.”

“...”

“Zero. Sleep, Twilight Sparkle. Sleep.”

Celestia felt the moment all of Twilight’s muscles relaxed completely. She caught Twilight in her magic and gently lowered her to the ground.

“Now, Twilight,” she said. “As your consciousness drifts, let your subconscious bubble to the surface, ready to listen. Can you hear me, Twilight?”

Though Twilight’s eyes remained closed and her breathing remained slow, her mouth moved. “Yes, your highness.”

“Very good. Now, I’m going to plant some simple triggers in you. Plant these triggers deep inside your mind, so that you will always recognize them, even if your conscious mind does not. Do you understand, Twilight?”

“Yes, your highness.”

“Okay. Listen carefully. Your first trigger is Submissive Sparkle. Remember how this current trance feels, how calm and safe and relaxed you are. When you hear Submissive Sparkle, you will fall right back into this trance. Let your subconscious accept that. Nod when you’re done.”

Twilight nodded, and Celestia continued. “Excellent. Now, when I say My Faithful Student, even if you are not in trance, you will feel the desire to follow anything I request. It will feel like the most natural urge in the world. You will trust me completely and obey my command without question. Do you understand, Twilight?”

Twilight nodded again, feeling the triggers take root in her mind.

“Lastly, Twilight, when I say Friendship Awaits, you will awaken from trance and resume your normal life as if nothing has changed. This remains a secret between us princesses. Do you understand?”

Twilight nodded one final time. Like a student studying flashcards, she wrote the triggers deep into her memory, eager to activate them when her mentor desired.

“You’ve been wonderful tonight, Twilight,” said Celestia, patting her student on the head. “Now, My Faithful Student, let your tired mind rest. We have much to discuss tomorrow.”

And Twilight knew no more as she descended into blissful darkness, her last thoughts of love and obedience toward Celestia before drifting into peaceful slumber.

Your Part [Alternate Version]

As Twilight watched the Maretonian dignitaries exit the palace, she pondered how much effort Princess Celestia could have saved had she simply magicked an illusion of Twilight to appear instead.

Though Twilight knew her role was small, she’d hoped she could’ve played some larger part regardless. Maybe caught the Maretonians’ attention with her knowledge of their tax system or bodies of government. Anything she could’ve learned something about, or been useful for. But all they’d done was thank her for keeping herself out of their confidential discussions. Twilight didn’t want to admit it, but it hurt a little.

Was she not important enough to know? Was all she was good for as Equestria’s newest princess the royal equivalent of scrubbing dishes at The Hay Burger?

Hiding her frustration as best she could, she turned to face the other three princesses. “Is there anything else I can do to assist with their visit?”

Cadance looked at her sympathetically. “I'm sorry, Twilight, but their visit is already over.”

“Oh.” Twilight's ears drooped in disappointment.

“Something wrong?” Luna asked.

“I guess I just don't really understand why I'm here.” Twilight let out a heavy sigh. “I get that the princesses have to keep appearances. But it seems like since I’ve become a princess, that’s all I’ve had to do.”

She pointed at the alicorns one at a time. “Princess Celestia and Princess Luna, you raise the sun and moon and run Equestria together. Princess Cadance, you protect the Crystal Empire. But me? There’s nothing new I’ve been able to do since becoming a princess, except… smile and wave.” She turned toward Celestia. “Princess Celestia, you’ve done so much for me, and I am truly grateful. But…” Her eyes looked away. “I don’t know if I really deserve the title of, well, ‘Alicorn Princess.’”

Celestia approached Twilight and touched a light hoof to her chest. “Trust in yourself, Twilight. Your time will come.”

“But isn’t there anything else I can help with?” Twilight asked. “Paperwork that needs filling? Meetings that need attending? Even if it’s just a little bit.”

Luna chuckled. “Nay, Twilight. We can handle our own administrative tasks just fine. You require no ‘princesshood internship’ to take your place among us. All you need is time.”

Twilight groaned. Though she tried to ignore the thought, some part of her told her she was useless, just an auxiliary backup princess in case the real princesses needed saving.

Celestia wrapped her foreleg around Twilight and drew her into a reluctant hug. “It is difficult charting one’s own path, yes. But when I sent you to Ponyville those many moons ago, I had every faith you would find your way, and that faith has never waned.”

Twilight looked up at Celestia with pleading eyes. “And I’m sincerely thankful, Princess.” She gave a short laugh. “And I guess you knew from the start. You, heh, didn’t tell me, but you knew.”

And there she was, Twilight Sparkle, newest Princess of Equestria. Yet, she felt like a newborn foal, even more clueless than the Cutie Mark Crusaders.

She hesitated to say it, but the words came spilling out of her mouth. “Is all this uncertainty and me feeling useless part of your plan too, Princess? Or am I just being primed for something else I don’t know about yet?”

Her cheeks burned. It felt so wrong questioning her role model, her mentor, but she needed to know. She squeezed her eyes shut, waiting for Celestia to berate her, maybe even say she made a mistake and that Twilight never should’ve become an alicorn.

Instead, nothing happened for a few silent moments. Celestia gave a long sigh, and she cautiously peeked her eyes open. Celestia was smiling softly.

“Well, alright,” said Celestia. She chewed her lip. “I suppose there is one thing I’ve been keeping from you. I’d been meaning to tell you later, but now is as good a time as any.”

Twilight watched raptly as Celestia looked around, as if observing her surroundings, before turning around to face Luna and Cadance. Celestia muttered a few phrases Twilight was just barely able to make out—“Sleepy Luna. Crystal haze.” Confusion clouded Twilight’s face as she watched their bodies briefly slump before straightening. A subtle shimmer seemed to ripple across their forms before they began walking around Twilight.

“Luna? Cadance? Celestia? W-what’s going on?” stammered Twilight. All of a sudden, her fur was tingling.

“Hush now, Twilight,” Celestia soothed, her hoof lifting the younger mare's head with gentle grace. “Close your eyes and trust in your teacher once more.” Though phrased kindly, it was clearly an order.

“O-okay, Princess.” Twilight swallowed hard but did as she was told. She took a deep breath, willing herself to trust Celestia once again. Heart beating rapidly, she bit her tongue as she heard Celestia’s magic activate.

After a moment, Celestia said, “You may open your eyes, my faithful student.”

So, Twilight opened them. “Princ- huh- wha-”

Celestia’s eyes were glowing, shifting. A mesmerizing kaleidoscope of color dragged Twilight’s attention in, and her breath caught in her throat as she gazed into the never-ending abyss of iridescent golds, bright whites, vibrant reds, lurid greens. With every pulse and glow, she found her head dragged toward their lapping swirls, thoughts and feelings evaporating, replaced with an inner calm.

It was hard for Twilight to tell where the spirals began and ended. With every passing moment, they only drew her deeper. Lose yourself in me, they seemed to say, and Twilight did.

Eyes heavy.

Thoughts slow. No thoughts when looking at the spiral.

“That’s right, Twilight,” said Celestia. “Focus on my voice, Twilight. Just keep looking into my eyes and sinking deeper, deeper.”

Had Twilight been looking at her reflection, she’d see Celestia channeling golden magic deep into her mind, casting a yellow glow over the spirals forming within her own eyes. She’d see her jaw slack, head barely nodding, almost as if drifting off to sleep.

She felt relaxed, so relaxed.

And yet, some last vestige of her knew something was wrong. Like a cornered dog, it clawed itself to the forefront of her mind.

“Ngh- no, this. Princess, what are you-” It was so hard vocalizing her thoughts. “This is-”

Before Twilight could finish her sentence, Celestia's voice cut in, her tone calm, but unwavering. "It is necessary, Twilight. You must trust me and let go of your doubts."

Trust Celestia. Let go of doubts.

Doubts.

“N-no!” It was so hard looking away from the beautiful spirals, but some small part of her forced her to try. “Luna… Cadance… help…”

Desperation welled up within her when she realized they were just standing there, as if completely oblivious to her plight. Their expressions remained jovial as they simply observed, wide, unblinking eyes almost staring through Twilight.

She needed help. Why weren’t they helping her?

“You d-did something t-to them…” she sputtered. “How could…”

Celestia pressed a hoof to Twilight’s lips. Even with just the touch, Twilight gasped in pleasure. It sent tingles through her head, as she found herself lost in the sea of Celestia’s closer gaze.

“Trust in me, Twilight. You’ll understand soon, just as they have. Isn’t that right, sister, Cadance?”

"Yes, your highness," they chanted in unison, their voices devoid of any inflection or emotion.

“Very good. And shouldn’t Twilight be good and listen too?”

“Yes, your highness.”

Celestia smiled and nodded, causing Twilight to nod along, following Celestia’s eyes. “Your fellow princesses are waiting for you, Twilight,” she said. “All you need to do is… submit.”

Immediately, the swirling colors in Celestia’s eyes seemed to take on even more of a life of their own, dancing and twirling in intricate patterns that drew Twilight in deeper and deeper. The colors shifted from gold to orange to pink and back again, each shade more vibrant and alluring than the last.

Twilight sunk into the hypnotic rhythm of Celestia’s gaze. It surrounded her like a warm, comforting blanket, her thoughts and worries threatening to fall away until there was nothing left.

And yet, the cornered dog lashed out even harder.

“Y-you’re not Celestia…” she panted. “You’re an imposter, a t-traitor…”

“Twilight.” Celestia looked at her with disappointment. “You wound me. Do you not recognize your mentor, the one that has guided you all these years?”

“Then P-Princess, w-what are you doing? This isn’t like you at all!” Twilight struggled to tear her gaze away, but turning her neck felt like moving concrete.

Celestia’s voice was calm and measured. “My faithful student, you must trust that I know what is best for my little ponies. I have always guided you to the light, have I not? All you must do to know is look into my eyes.”

As Celestia’s magic flared more intensely than before, Twilight felt her adrenaline spike, and some deep-rooted, instinctual fear took hold and yanked her head away. Panting at the effort, she stumbled away from her mentor’s touch.

In her mind, a single comment held sway: get away from Celestia. But in her dazed state, teleportation was not a possibility.

Twilight felt her head clear with every second she wasn't being subjected to Celestia's control. Time. All she needed was to buy time. With a weak cry, she channeled an offensive spell into her horn and fired it at Celestia.

Celestia parried it almost disappointingly. “Twilight, you couldn't let your mentor down like this, could you?”

Though the comment stung, Twilight hissed through gritted teeth, “My mentor would never try to mind control her subjects. This is wrong.” Concentrating further, she let off another barrage of magic, each blast more powerful than the last.

This time, Celestia put up a magic shield and let it simply absorb the attacks. She advanced slowly on the retreating Twilight. Her horn glowed a dazzling yellow, traces of hypnotic magic still lingering in her eyes, threatening to draw Twilight's gaze back in. “What I show my subjects is bliss, certainty. The confidence in knowing that with my guiding words they have nothing to fear. It feels good submitting to my spell. Accept it, Twilight.”

Twilight's legs wobbled as the memory of those smothering spirals invaded her thoughts again. Unintentionally, she let out a low moan. Yes, it felt good sinking into the spirals. Even now, they beckoned for her to succumb once again.

But no, she couldn't. Above anything else, she treasured her mind, and she wouldn't let Celestia or whoever this creature was lay claim over it. Taking to the air on unsteady wing flaps, Twilight resolved that if she couldn't teleport herself away, she would simply have to flee with her own two wings.

As she prepared to leap off the balcony and soar into the skies below, she yelped. She looked down at her tail and saw it was being held down. Not by Celestia's radiant glow, but by a dark blue shade. Luna's magic.

“L-Luna. How could-” The words died in her mouth as Twilight realized Luna still held the same smiling, unblinking expression she’d had before. Of course. Celestia must have brainwashed her already. That wasn't good—Twilight was both outnumbered and overpowered.

But she'd been in perilous situations before, and she wasn’t ready to give up. Racking her brain, she noticed Luna's movements were slow and sluggish. As Luna faced Twilight, she seemed uncertain, almost as if she wasn't sure what to do with her body without Celestia's command.

Fine. If magic wouldn't work, she'd have to do it with more force. “I'm sorry, Princess Luna,” she shouted. Dropping to the ground with a noticeable thud, she leapt toward Luna, and the two mares grappled, struggling to overpower each other. Yet, Luna's body felt slippery and squishy to the touch, seemingly impervious to Twilight's blows. At the same time, it felt as if Luna still struggled to fight back, her body squeaking loudly, her own blows cushioning off Twilight.

Breathing heavily, Twilight rolled away from Luna as she saw Celestia continue to advance toward her. It seems as though Celestia was in little of a rush. She'd made no effort to incapacitate Twilight, instead, her horn still alight and causing residual magic within Twilight's mind to emit a persistent and dizzying throbbing.

“You should know better than to fight your mentor,” Celestia said.

“Yes,” monotoned Luna, her voice oddly muffled. “Join us, Twilight. You'll be so much happier when you submit.” She took a step forward.

As the two mares inched ever closer to her, Twilight tapped into every magical reserve she had. Forcing her frenzied mind to concentrate, she tried to access her teleportation magic once more and found it nearly within her grasp. Agonizingly slowly, her horn flared to life again as she crept ever closer to activating the spell, closer, closer.

Then, she bumped into something behind her and felt her wings press into something cold, almost rubbery.

Oh, she’d forgotten about Princess Cadance.

She yelped as Cadance wrapped her hooves around Twilight and dispelled her magic with a single tap. Clinging on tightly, immobilizing the flailing mare, Cadance looked up expectantly as Celestia finally reached the pair and put her hoof back onto Twilight's trembling chin.

“I have something for you,” said Celestia. “It was meant to be a surprise, but the situation calls for some improvisation.” In a blink, she teleported something in between them, and Twilight's eyes widened.

Twilight saw something that looked like herself, but not like herself. Celestia was holding what looked like a shiny suit made exactly in Twilight's image, mane, tail, and fur replaced by smooth, shiny, colored rubber. Its eyes were wide, sparkling in a manner that matched its toothy grin. There was a separated seam in the back, and Twilight watched in horror as Celestia began opening it up.

As Twilight continued flailing in Cadance's grasp, she couldn't help but notice how smooth, yet squeaky her sister-in-law felt. Straining her neck to turn around, Twilight stared, betrayed, at Cadance’s unchanging face, the corners of Cadance’s mouth straining against her grin.

As Celestia continued drawing the suit closer toward her, everything clicked. Why Luna and Cadance had seemed so happy to be there, so squeaky, so rigid. She couldn't believe she hadn't noticed sooner.

“Even just minor illusion magic does great wonders where one does not expect its usage,” said Celestia, as if reading Twilight's mind. “It's better if the ponies don't know. As for you, Twilight, struggling will only make it harder for you to put this on. Please, for me.” Celestia lowered her head until she was at eye level with Twilight. “All I need is for you to drop.”

Immediately, her eyes filled with renewed spirals, blasting waves of pure bliss directly into Twilight’s vision. Even at just the mention of the word drop, Twilight felt the hypnosis roar back with a renewed vigor, and it didn't take long for her eyes to droop and her mouth to fall slack again. As Celestia's magic smothered her mind, she almost didn't notice as her mentor gently lifted her hoof and began slipping it into that of the rubber suit’s.

“A lullaby to soothe your troubled mind, my little pony,” said Celestia. She briefly turned and beckoned for the other princesses to approach, before beginning with a gentle lilt.

Your destiny's uncertain
And that's sometimes hard to take
But it will become much clearer
Once you're suited for our sake

Celestia gently raised Twilight's other leg and squeezed it into the suit's hind leg. A part of Twilight still fought against the control, but even as she weakly flailed and kicked, it was within the confines of the rubber, which kneaded against her skin and sent shivers up her spine that weakened her resistance even further.

Luna continued the verse, her voice soft and melodious, blending seamlessly with Celestia's.

Patience is never easy
I understand wanting more
But you must show obedience
To spread out your wings and soar

Luna rubbed against her sister like a friendly kitten as she approached Twilight. Gently massaging Twilight's chest, she grabbed at the folds of the rubber suit and helped pull it up even further over Twilight.

Princess Cadance joined in, her voice muffled but sweet as she took up the next verse.

You stand here for a reason
My voice is as soothing as it’s strong
That rubbery crown is upon your head because
You will belong

As Twilight quietly moaned and trembled, Cadance, having fulfilled her duty to hold her sister-in-law down, softly pressed Twilight's mouth closed and ran her hoof through Twilight's hair. “Hushhh. It's going to be okay.” Obediently raising Twilight's arms and wings, she lovingly guided them into the rubber material, as if nurturing a delicate flower ready to bloom.

Their voices washed over Twilight, stirring something deep within her mind. A warmth spread through her body with each note, loosening her thoughts and relaxing her will.

Together, the princesses harmonized, their voices blending in a beautiful chorus.

Know that your thoughts are drifting soon
As the sun rises, so fades the moon
As love finds a place in your heart
You are a princess; obey your part

Luna brushed a hoof against Twilight’s cheek before continuing.

Don’t you feel yourself wanting more
A chance to surrender, a chance to soar

With Luna’s touch, Twilight felt her eyes become unfocused. Her view blurred and faded as the lullaby fogged her mind.

Cadance lovingly put a wing around Twilight’s back and took up the next verse.

Today is the day you're tightly bound

And as the song reached its conclusion, Celestia pulled the mask of the suit over Twilight, watching as the poor mare practically squirmed to insert herself into it. No, she wouldn't withhold it from Twilight for long. With tender care, she began stretching it over Twilight, and soon Twilight's blissful face was completely encased in that wide, unblinking smile.

Finally, the three princesses joined together in one final verse.

Know that your thoughts are drifting soon
As the sun rises, so fades the moon
As love finds a place in your heart
You are a princess; obey your part

“Your time will come,” murmured Celestia. “Follow my words, and feel bliss in your obedience.”

“Obey your princess, Twilight,” Luna said.

“Obey your princess,” Cadance parroted.

The words sunk into Twilight like stones in a tranquil pond. Inside the suit, she felt every aspect of herself being smothered, overwhelmed. She fixated on a new set of dazzling spirals that seem to entirely surround her vision, coming from within the suit itself. At the same time, she heard salacious whispering echoing in her encased ears. Obey Celestia. Rubber is bliss. Love the squeaks. With every second, she felt the turmoil in her mind still, replaced by a blissful tranquility. Though she still stood on all four legs, her posture slackened as every muscle in her body let go of any stress and threatened to collapse her to the ground in a blissful sleep. She struggled to keep her eyes open, the hypnotic spirals the only thing keeping her afloat.

In Twilight’s scattered mind, the words of her trusted mentor and friends made sense. Her mouth moved almost of its own accord. “O-ob-ob-b…” But still, some last part of her resisted.

“Take your time, Twilight,” said Celestia. “Let the words bounce around in your mind. Let them absorb into you, into your being. Let every word make you even more tranquil, at peace. Can you do that for me, Twilight?”

Twilight only sighed in response, her head bobbing in time with the spirals. Thoughts of giving in echoed deep within her, making her feel even more calm. The sensation of rubber expanding and contracting around her chest from her slow, methodical breathing became almost a source of soothing familiarity.

“It feels good following my words,” said Celestia. “It feels good letting all that stress disappear. So much better letting me do the thinking.”

Twilight tried forming her own thoughts and found she could not. Obeying her princess and letting Celestia take control of her thoughts felt comforting, safe.

Celestia cupped Twilight’s chin in her hoof and leaned in even closer. “Now try again, Twilight,” she whispered, her breath hot on Twilight’s face. “All I need is for you to fall.”

Twilight’s body trembled with conflicting emotions. A part of her wanted to resist, to break free from the hold of her princesses and reclaim control of her own mind. But another part of her longed to surrender completely, to let go of her worries and fears and simply obey.

It felt so nice having Celestia so close, filling her mind with hazy pleasure. She liked having Celestia’s voice in her head. Liked how the suit permeated her mind with the smell of clinical rubber that bordered on the faint scent of blueberries. With the other princesses urging her on amidst her own uncertainty and fear, it felt so much easier just following the long, narrow, welcoming passage of Celestia’s command.

Like a rubber band being pulled in two different directions, she began to feel her resistance let go. For a moment, she remained suspended in this state of tension until finally, with a whimper, her doubts slinked away, and the rubber band could do nothing but hurtle in the opposite direction. Pleasure coursed through her entire body as everything seemed to just click into place, and Twilight squirmed and writhed in bliss. She squeezed her eyes shut, her breath coming in short gasps and her mouth open in a silent moan of ecstasy.

When she opened her eyes again, they were glazed over, pulsing with the same brilliant light as the spirals enveloping them.

“Yes, your highness,” she said, her voice muffled by the suit. “I obey. I am yours to command.”

Celestia smiled, the corners of her eyes crinkling with warmth, and Twilight's heart swelled. She leaned eagerly into Celestia's nuzzle, suit squeaking away, craving her affection and praise like a parched flower craving rain. "That's my good princess," Celestia purred, and Twilight glowed at the endearment, longing to prove how good she could be.

Celestia turned to face Luna and Cadance, who were both standing at attention now that their jobs were complete. “At ease, princesses,” she said. “I am very proud of the work you’ve done today.”

Immediately, Luna and Cadance softened, wings folding and heads bowing in unison before their ruler. “Thank you, your highness,” they intoned. They stepped back, no longer having any orders to follow upon Twilight's submission.

If Twilight could see through their suits, she'd notice much the same experience as her own. Love the squeaks. Love the creaks. Obey Celestia. Rubber is bliss. Happiness is glossiness. Luna and Cadance’s minds were all but present, long having been entranced by those sensual spirals. All they felt now was pure bliss at having successfully carried out Celestia's commands.

But, Twilight could see how they trembled in pleasure underneath their suits, soft gasps betraying their blank, grinning faces. Finally, it made her feel like she belonged. They must’ve been so happy welcoming her into Celestia’s thrall.

Celestia turned back to Twilight. “Now, I hope you realize the joy they feel in obedience.” She slowly ambled out onto the balcony, looking at the night sky. “After returning from her banishment, Luna was… troubled. She feared the Nightmare would come and reclaim her. Now, such a thing will never happen again. Isn’t that right, Luna?”

Luna bowed again. “Yes, sister. Thank you for saving me from myself once more.” As if repeating a mantra, she added, “There is no envy or jealousy in obedience.”

Celestia nodded. “Very good. And Cadance’s kingdom was always so distant from my own throne. What if she was kidnapped by Chrysalis again? Or corrupted by Sombra? I needed to make sure they could not get to her mind first.”

Cadance followed suit beside Luna. “My mind and kingdom are yours, Aunt Celestia. Obedience means peace and security.”

“Well put, Cadance.” Celestia ran a hoof over Cadance’s suit, causing her to moan in pleasure as the rubber squished and creaked. “These suits serve as the perfect way to both reinforce my control and act as the perfect disguise to conceal what’s hidden underneath. I’m very pleased yours seems to fit you so well, my faithful student.”

She faced Twilight once more. “And now, the time has come for me to extend my control to all of Equestria’s princesses. Come, Twilight.” She beckoned for Twilight to approach, waiting upon her uncertain, squeaky steps. “I hope you understand now why I have kept you in the dark until today.”

Twilight’s newly enthralled mind understood perfectly. She felt only devotion and a wish to serve as Celestia commanded. “Yes, Princess. I understand now.”

“Then,” Celestia said, her expression darkening, “do you understand now why you should not have doubted me?”

Twilight’s gut twisted. She didn’t know why she hadn’t trusted Celestia in the first place. “Yes, your highness. It was wrong of me to resist. Please forgive me.”

“Worry not, my dear Twilight. All is forgiven.” Celestia’s frown faded, and she wrapped a wing around Twilight and pulled her close, massaging her rubbery exterior. “There, I think that suits you a lot better.” She raised Twilight's new squeaky chin and asked, “What do you think of me now, Twilight~?”

“I'm sorry, Celestia. You're right. You're always right,” Twilight said. “I'll never disobey you again. Forgive me, Celestia.”

Celestia pet Twilight’s new rubbery mane. “Good girl.” The words made Twilight shudder in delight. “You have always deserved your alicornhood, Twilight Sparkle,” she said. “Your intelligence and ability have always had the potential to rival us all.”

Twilight bowed her head slightly. “Thank you, Princess. I am honored by your praise.”

“But you were too uncertain, too naive,” Celestia continued. “You needed someone to guide you, command you. I hope your new role serves you well.” She allowed herself a wry smile. “My little princess. My little hypnotized puppet princess.”

Twilight almost purred at the title. It felt like a badge of honor, a symbol of her devotion to her mentor. “Please command me as you see fit, Princess.”

“Very well.” Celestia coughed and straightened her posture. She intensified her magic, and Twilight felt the spirals within the suit intensify, dragging her even deeper under their spell. When Celestia spoke, her voice was once again filled with authority. “Now, Twilight, let my words fill your mind. Let my thoughts become your thoughts. Let yourself sink deep into relaxation again. Deep breaths, in and out. Good.”

She waited briefly for Twilight to fully settle in before continuing. “Now, in a moment, I will bring you fully into trance. Let yourself accept that. Do you feel sleepy, Twilight?”

“Yessss,” slurred Twilight, her eyelids already drooping. She squirmed inside the tight rubber suit molded perfectly to her body, listening to the squeaking of the rubber echoing inside her ears. She could feel her mind starting to drift even further as the suit caressed and enveloped her.

“What an excellent, compliant princess.” Celestia leaned over and began lightly massaging the rubbery exterior of Twilight’s shoulders, eliciting a chorus of light gasps and the crinkling of the suit’s material. “That's right my little pony, just relax and let the suit take hold of you. Let me count down for you, and with each number, feel yourself sink even deeper.”

“Five. Feel the rubber hugging your curves, conforming to your every contour.”

“Four. The squeaking filling your ears, lulling you into a trance.”

“Three. Your vision obscured by the mask, leaving your mind open and vulnerable.”

“Two. Shhhh, don't fight it my pet. Let the suit claim you, let it squeeze out any last traces of resistance.”

“One. So close you can feel it.”

“...”

“Zero. Go limp for me, surrender yourself to the rhythmic squeaking, that feeling of enclosure and compression. Sleep, Twilight Sparkle. Sleep.”

Celestia felt the moment all of Twilight’s muscles relaxed completely. She caught Twilight in her magic and gently lowered her to the ground.

“Now, Twilight,” she said. “As your consciousness drifts, let your subconscious bubble to the surface, ready to listen. Can you hear me, Twilight?”

Though Twilight’s eyes remained closed and her breathing remained slow, her mouth moved. “Yes, your highness.”

“Very good. Now, I’m going to plant some simple triggers in you. Plant these triggers deep inside your mind, so that you will always recognize them, ready to obey at a moment’s notice. Do you understand, Twilight?”

“Yes, your highness.”

“Okay. Listen carefully. Your first trigger is Submissive Sparkle. Remember how this current trance feels, how calm and safe and relaxed you are encased in the suit. When you hear Submissive Sparkle, you will fall right back into this trance. Let your subconscious accept that. Nod when you’re done.”

Twilight nodded, and Celestia continued. “Excellent. Now, when I say My Faithful Student, even if you are not in trance, you will feel the desire to follow anything I request. It will feel like the most natural urge in the world. You will trust me completely and obey my command without question. Do you understand, Twilight?”

Twilight nodded again, feeling the triggers take root in her mind.

“Lastly, Twilight, when I say Friendship Awaits, you will awaken from trance and resume your normal life as if nothing has changed, as if you can’t notice all those little squeaks and creaks and colorful waves around your eyes. This remains a secret between us princesses. Do you understand?”

Twilight nodded one final time. Like a student studying flashcards, she wrote the triggers deep into her memory, eager to activate them when her mentor desired.

“You’ve been wonderful tonight, Twilight,” said Celestia, patting her student on the head. “Now, My Faithful Student, awaken, and let us return inside the castle. We have much to discuss tomorrow.”

Twilight's eyes fluttered open, the hypnotic haze lifting as she awoke from her trance. She nodded dutifully and followed Celestia inside, her rubber suit crinkling with each step, her every thought filled with love and obedience toward her trusted mentor.

Twilight awoke as the first rays of morning sun filtered through her blinds. The comfort of her temporary castle bed cradled her as she blinked away the last remnants of sleep.

How had she gotten here? Memories of the previous night were hazy in her mind, and trying to pick through them felt like meandering through a thick fog. She recalled Celestia, and her furrowed brow quickly melted into an unfocused smile. If Celestia had been there, Twilight had nothing to worry about.

There was a knock on the door. “Twilight?” Spike’s voice called out. “Breakfast is ready.”

Twilight moaned softly, shifting around in bed. As she did, she felt an unusual tightness restricting her movements. It made her feel reassured… safe. Every little wriggle sent addictive tingles coursing up and down her body, and she lost herself in the sensations for a brief moment.

“Is everything okay, Twilight?”

Twilight heard her door click open, and Spike’s concerned face peeked in. She stared dumbly at her assistant, her mind still adrift on a sea of bliss. So peculiar the experience was that she could-

No. These feelings are normal. There is no need to question them.

That was right. She didn’t need to tell Spike about something so ordinary. He just needed to know she was perfectly okay.

“Mmph mmphm phh.”

Odd. Twilight blinked in confusion, surprised by the muffled sounds escaping from what felt like a gag but it was perfectly normal and there was no need to question it.

Spike raised an eyebrow. “If you say so, Twi. I’ll be waiting at the table.” With a nod, he turned and left, closing the door behind him.

See? Spike had understood her just fine. The spirals around the corners of her eyes pulsed happily in reward for her good behavior.

She got out of bed and stretched, enjoying the tightness and blissful squeaks and creaks surrounding her. Dozens of plans unfurled within her mind, and she allowed herself a moment to bask in anticipation.

It was going to be a wonderful day!
