Twilight felt the hysterical giggle trying to rise to her lips, and pressed it down firmly. If she started, she wasn't sure she'd ever stop.

Princess Luna, the glorious Princess of the Night, the magnificent, the powerful, the endlessly beautiful, was kneeling mindlessly in her living room. Her power, her magic and her perfect body were hers to command, her mind hers to reshape into whatever she wanted.

Her hand trembled as she wrote, out of practice at writing with her hand, but her magic still throbbed with the dull ache of overuse. The first line read 'What.' This had been crossed out. Below, it continued 'Why did Princess Luna come here? Is this another failsafe? Why did she only enter her charmed state when she crossed the doorway? Does anyone know she's here? Does anyone know about me? Will Celestia notice her absence? Have I gotten away with it? Why did she say so much when she awakened?'

It was the middle of the night. At the very least, her absence probably wouldn't be noticed until morning...

Twilight looked out of a high window, at the moon shining gently between the branches. A moment of stillness came and went, then Twilight began to giggle. It broke into heaving laughter, hysterical, borderline terrified, and it took her several minutes before she could rein it in. Finally, clinging to the dresser, she managed to write 'Don't forget to make Luna lower the moon.'

She had literally taken possession of the Goddess of Night. The knowledge kept forcing little trembling giggles of disbelief past her lips, even as she dragged a chair across the floor and sat down before Luna's motionless form. She took a deep breath.

Okay.

"P-Princess Luna."

Luna's gaze hadn't ceased tracking her since the moment she knelt, but somehow, she seemed to listen more intensely upon being addressed. She wore the dark blue tunic and breeches from Twilight's dream, small, modest cut outs exposing the cutie marks on her thighs. She was power and grace, dignity personified, and she was still kneeling on Twilight's floor. Her hair billowed soundlessly despite the lack of breeze.

"I. Um. Why did you come here?"

"I was not in thy presence, my Goddess." Luna replied with serene sincerity.

She hadn't ever experimented with triggering any of the others when she wasn't standing right next to them. Or was it a safeguard against triggering someone in public? No, that couldn't be it. She'd awakened Applejack in front of Rarity, and even if Rarity had been under her control too by then, Applejack couldn't have known that. Unless the spell did. She'd have to try it somehow. That would mean triggering one of her toys - her friends, she corrected firmly - in front of someone she didn't yet possess, but she could always charm them afterwards...

Triggering the charm at a distance was harder. Maybe she could make something to relay her voice, and try that under controlled conditions? Surely a recording of her voice wouldn't work, or the charm would be horribly insecure... She made rapid notes. Clearly she'd been spending too much time having sex and not nearly enough time experimenting to find out more of the charm's rules.

Twilight looked up. "Do you have to come to the person who charmed you when you're awakened?"

"Yes, my Goddess."

Still, that didn't explain why she'd come inside first. Was she compelled to seek privacy first? "Luna, why didn't you awaken as soon as I opened the door?"

"I was not in the same location as you were, my Goddess."

Objecting 'Yes, you were' wouldn't achieve anything. She had to phrase the question better. She really had to find out why Luna kept addressing her like that, too. "Where was I, and where were you, when I opened the door?" she hazarded.

"You were inside thy house, my Goddess, and thy unworthy slut was outside it."

That made sense. She'd stepped inside, then they were both inside Twilight's home, so she had succeeded in coming to Twilight and awakened. Could it be that she'd have been as specific as coming to the room Twilight was in? More experiments.

She moved down the list. "Does anyone know you're here?"

"You, my Goddess." Luna replied blankly.

Haystacks. She had to be specific. "Does anyone other than myself know or suspect you are in Ponyville?"

"No, my Goddess."

"Does anyone have a reason to wonder where you are- no, never mind that." Too vague. "Do you believe anyone is alarmed or concerned about your behaviour after you met me in my dream?"

"No, my Goddess."

A good sign. Whatever compulsion she'd been laid under, she probably hadn't done anything so obvious that she'd have worried people when she left. "...have you suspected for long that I was using a spell to control other ponies, and have you told anyone?"

"I have suspected thy use of such power for more than a week, my Goddess. Thy humble servant has not told anyone of her suspicions."

"Will -" Twilight swallowed, feeling the name stick in her throat, but she managed to continue. "Will Princess Celestia worry, if you don't speak to her for a few days?"

"Only a little, my Goddess. It is not unknown for thy worshipper to spend time away from Canterlot."

This was the really important one. "Do you think anyone suspects my secret?"

"Yes, my Goddess."

Twilight stiffened slightly. "Who?"

"Thy friend Pinkie Pie suspects something is amiss, my Goddess. She has consulted Zecora of the Everfree Forest. Zecora does not yet seem to believe."

Pinkie Pie and Zecora. Okay. She had intended to ask Pinkie to join them, and even allow her to turn her down, though she was still worried about her strange not-quite-magic. Zecora would just have to be next. A vision of the striped pony on her knees flashed before her, not for the first time, and she lingered on the idea before she finally put it to one side. Celestia didn't yet suspect, that was the important thing.

She just couldn't face the thought of the sheer disappointment and outrage on her mentor's face that knowing the truth would bring. Especially now she'd charmed Luna. The very fact that she'd succeeded in using it on her, even with the full power of her desperation in casting it, meant that the charm was very, very powerful indeed. Twilight checked the last item on her list; the way Luna had announced her awakening. It had been pretty lavish. And enjoyable.

"What made you declare my ownership of you when you awakened, Luna?" she asked mildly, eyes still on her list.

"I was ordered to speak thusly when I am awakened."

Twilight jerked bolt upright. "What?"

"I was ordered-"

"Is this the first time you have been charmed by this spell, Luna?" Twilight demanded. Her heart pounded, shocked to her core.

"No, my Goddess." Luna replied serenely.

"But - who? Who did this to you?" Twilight's eyes were wide, and she had a horrible premonition of what Luna was about to say.

She was wrong. "Celestia, my Queen, my Goddess." Luna answered, in tones of brainwashed calm.

Twilight's mouth fell open. "But- what- I- what, Celestia?!"

"Yes, my Goddess."

That couldn't be true. It couldn't! Celestia would never, she could never, she wouldn't even think of such a thing, she just, just...

'I have been the greatest of fools to ever consider myself thine equal.'

No. Surely...

'You are my Queen, my Goddess, and I thy unworthy supplicant.'

...surely, she wouldn't...

'I worship thy divine body.'

...but she had. The words had never been intended for Twilight. They were to be spoken when Luna was awakened by her true owner.

Her sister, Princess Celestia.

The quill dropped from her nerveless fingers. This was impossible. Celestia? The soft spoken ruler with a heart great enough to encompass all ponykind? The radiant sun in pony form? Fucking her sister?!

There was just no way.

"Are you sure?" she asked desperately, despite realising how nonsensical the question was.

"Thy slut is sure, my Goddess."

But why was Luna addressing Twilight that way? The devotion she'd recited was tied to the moment she awakened, but surely whoever (Celestia) had charmed her, they would have told her to address them as Goddess.

Hang on. "You were told to address 'your Goddess' this way, weren't you? Specifically, told to speak like this to 'your Goddess'?"

"Yes, my Goddess."

"And the person who awakens you, you declare they are your Goddess, don't you?"

"I do, my Goddess."

"So whoever awakens you is your Goddess, and has to be addressed appropriately?"

Luna nodded. "Yes. You are my Goddess, Twilight, and I thy humble whore for thy use."

That was it. The instructions weren't meant to work that way, but until Luna had been charmed by someone else, they (Celestia!) would never have realised.

Okay. Even if... even if Celestia had charmed her, she might not have done anything to her, right?

'I am thy craven slut, thy whore.'

That could have just been something Celestia made her say, without-

'My ass is thine to abuse.'

-without acting on it. She tried to speak slowly, and calmly. "Luna, has Celestia ever touched you, um. Sexually?"

"Yes, my Goddess. Do you wish to hear of thy whore's degradations?"

Twilight's mouth dropped open. Luna gazed at her patiently. "I- yes?" she replied weakly. "Tell me."

"I will speak of a degradation. Celestia, my Queen, came to me whilst I was gazing upon the moon one night. I was that foolish self which could not understand her true majesty, and bade her leave. I was concentrating on the stars, and felt no wish to speak. She commanded my awakening, and I yielded. My mind yielded. I became desperate to obey her every desire. I understood her divine power. I grew aroused, eager to offer her my body. My sex shone as I removed my clothes."

"Wait." Twilight managed. Luna was more articulate in her awakened state than any of the ponies she'd charmed before. Was that because Celestia was better at commanding her? Did she have pre-existing orders to be more verbose? And, she had to ask-

"Are you wet for me, Princess Luna?" she whispered.

"I am, my Goddess. I am aroused when I am charmed. My body must be ready to perform for thy pleasure. My sex is thine." the Princess replied compliantly.

Twilight squeezed her eyes shut. Princess Luna was on her knees. Wet for her. Almost begging to be used. She couldn't handle the sudden twist from open mouthed, end-of-her-world horror to one of the most terrifying, arousing things she could have ever imagined. Her body didn't know what to do. Twilight gripped the chair arm tightly, pushing out word by word "G-go on, please continue. Um. And, um. S-show me."

"I will reveal that which is thine as I speak." Luna's gloved fingers moved to the buttons of her tunic, and she slowly began to undo them, one by one. "My Queen wore a dress of purest white silk. The skirt fell in waves from hip to toe, elaborate and embroidered with delicate images of the sun, that which was her mark and domain. Thy foolish slut had not realised that which she wore beneath, concealed by the billow of her perfect garments."

Twilight leaned forward, unable to stop herself. The tight fitting tunic burst open as the final button released, revealing a sleeveless white shirt beneath, and the mesmerised pony wriggled her shoulders to work the tunic down her dark arms. "It was then that she chose to unbind her skirt, and allowed it to fall to the floor in a shimmering pool. Revealed, I beheld a stout white shaft of pure porcelain, bound to her hips by an elegant harness of white leather. These, too, were marked by the symbol of my Queen, the unconquered sun."

Luna lifted the shirt over her head, the fabric momentarily gathering her mane of stars and darkness together, then it was released again as the shirt dropped to the ground. Her modest dark blue breasts swelled behind a bra of almost the same shade, detailed with intricate lace, with a pristine white moon forming the front clasp. "Bewitched, those memories which had been taken from me were returned, and I recognised this shaft. It had taken my mouth, my sex, slid oiled betwixt my breasts. It was a tool of her power, and my worship. I moistened further."

Twilight gazed at Luna with rapt fascination as she spoke, watching her lips shaping each word with a kind of archaic precision. She'd had never realised how sexy her accent could be before, how hot it was to listen to that voice describe her body being fucked by her Mistress. Her sister. Twilight was barely aware of her own whisper. "Be more detailed."

"I will give you every detail." Luna slowly stood up, and swayed her hips from side to side as she undid her breeches. Turning, she bent over and presented her ass for Twilight's appreciation as she worked her knee high boots down her legs, and off. "I licked my lips. I anticipated that my Queen should fill my mouth with her shaft. She often did this while I was in her thrall, to moisten the shaft to penetrate my yielding body. She spoke, her voice soft and rich. She spoke to me as a mother speaks to their child, with warmth and compassion. 'My beloved sister,' she said, 'I would be very happy if you would suck your Queen's cock. I should hope that you would finger thy sex while you worship me.' I could not deny her request. I had no wish to. I collapsed nude to my knees and parted my lips, sinking my mouth over her smooth, cool shaft. Thy slut's fingers found their home within mine sex."

Luna hooked her fingers into her waistband, and worked her breeches down her legs. Inch by inch, her firm ass came into view, scantily covered by lacy panties which matched her bra. Her cheeks were marked on both sides by a pool of darker, midnight blue and Twilight watched, entranced, her hand slowly reaching out but not quite daring to touch. Luna's tail swayed, an arch of stars. "There was silence, broken only by the wet sound of my fingers within mine sex, and the smack of my lips upon my Queen's shaft. She stroked my head, and spoke. 'You've worked very hard at getting better. I'm very proud of you, Luna.' I glowed with joy, and drew her divine cock deeper into my mouth. I wished with all of my heart to praise her aloud, but could only wish that my Queen wouldst see the worship in mine eyes as I looked up at her, my lips shaped around her perfect shaft."

She could picture it. She could hear the words, in that familiar voice. Almost hear them spoken to her. You are my most devoted fucktoy, Twilight. Her fingers grazed Luna's skin and they both jerked as one, Luna gently pressing her ass back against Twilight's hand, while Twilight struggled to deal with the wave upon wave of arousal and confused lust crashing down upon her. After a moment, Luna slowly turned and took hold of the front clasp of her bra. "I fellated her faster, thrusting my fingers into my sex and driving my hips against them, and it seemed to me that my Queen sensed my urgent pleasure, for she lifted a hand. I ceased all movement at once. 'You look just wonderful, my dearest sister. I would wish for you to take hold of the railing with both hands, and offer thy cunt to me. Would you do that?' she asked. I lifted my head from her glorious shaft, tempted to move with excess urgency but constrained by her previous commands to shift position with gracious calm, and gazed longingly into her beautiful eyes."

Luna unfastened the catch, and let the bra fall open. Her firm, proud breasts stood out from her chest, dark nipples achingly hard and blue-black. "'I could wish for nothing more than the honour of being thy unworthy whore, my Queen. I beg of thee, ravish my body with all thy might. All that I am is yours.' I turned and lifted my ass on high, parting my legs and allowing my Queen to do as she wished with my glistening sex. I felt the night breeze upon my bare skin and looked out over the railings for league upon league, gazing at the scattered lights like earthbound stars and wishing truly that all ponykind should step outside and look up, to watch my humiliation. I felt the saliva slick touch of the cool porcelain shaft against my heated nethers, and I groaned with deep and abiding lust. I gripped the railing tighter, for fear I would thrust myself back in too great an urgency. It was my sister, my Queen, who would dictate how and when I was roughly fucked."

Luna's fingers slid into her panties, her sparkling eyes gazing into Twilight's with the mindless attentiveness of the focused. Each movement was unnaturally smooth, a thoughtless calm underlying her words. "'Please, fuck thy whore. I do not deserve it, but I crave it. I beg of you, my Queen. I cannot live without it. Fuck my eager sex.' I wished for nothing more than to be her sexual plaything, forever. She laughed, softly. 'Very well, Luna. Just this once.' she teased me, and she thrust her shaft into my body. It was bliss. It was the purpose of my being."

The enthralled princess bent forward, and pushed. Her panties slid down her thighs and dropped loosely to the ground, flicked aside by her foot to land neatly with the rest of her shed garments. Straightening, Luna parted her thighs and rested one hand lightly at her hip, fully exposed. Her sex was bare, flushed deeper blue and glistening with eager wetness. She was naked, beautiful, and perfect. Twilight whimpered aloud.

"Show me-" she managed, swallowing. "Show me how you touched yourself."

Luna folded gracefully to her knees once more. "I will show you the way I touched myself at my Queen's command, my Goddess." Her hand slid between her thighs, and slowly, deftly, she began to stroke her parted fingers up and down her slit. Wetness gleamed on her fingertips. Her lips formed a pale blue ring, and smoothly, she leaned forward and began bobbing her head back and forth as she worshipped a shaft that wasn't there.

Twilight's mouth fell open. That wasn't what she'd meant! She'd just wanted Luna to play with herself, not re-enact the scene she was describing...

Luna was gasping, quick, sharp little breaths as her fingers slid in and out of her. Almost without meaning to, Twilight slowly rose to her feet, and stepped forward. Luna's eyes met hers, worshipful, hungrily aroused, and her mouth sank deeper until her lips brushed Twilight's pyjamas. Her head was tilted back, slender horn bobbing in the air, fingers buried deeply in her cunt.

Uncontrollable lust flooded over Twilight like a dam breaking. All her hesitation and confusion fell away, destroyed by her single need. Buttons flew from her top as she yanked it open, baring her small breasts to the air, shrugging out of her top and dressing gown in one jerky movement. Feverishly, she yanked down her pyjama bottoms and kicked them aside, before taking her place nude in front of Luna, standing over her.

"You worship me. Me." Twilight whispered, and Luna gave an urgent nod, unable to reply as she re-enacted her worship of her sister's artificial cock. Twilight's own fingers found their way to her sex and stroked roughly. "Keep fingering yourself, and go on with your story!" she commanded shakily.

"I will continue as I finger myself, my Goddess. My Queen's shaft slid into my body, and I cried out aloud with joy to be so defiled by her. I could not see her, only gaze into the dark and hold fast to the rail. She chastised me, with tender words. 'Luna. If you keep making such noise, everypony will hear you.' I could not have desired such humiliation more, but my Queen did not yet wish it. 'Thy whore offers her deepest apologies!' I panted for her. She drove the shaft firmly into mine nethers, over and over, gathering my tail into her hand and drawing me back against her thrusts. I cried out for her. She struck my ass, and I thanked her. 'I beg thee, fuck your humble slut! Fuck thy property!' I shook. I trembled. I could scarcely breathe."

Twilight knew how she felt. She could barely stand, her shoulders shaking, her fingers desperately thrusting in and out of her, watching Luna's hands and mimicking her every move. Her body rocked, barely able to cling on, shuddering at the edge of orgasm. Luna's voice continued relentlessly, her calm tones coloured by the arousal wracking her body. "I could no longer restrain myself. My resolve weakened and I found myself to be desperately thrusting back with my hips. My Queen laughed once more, a soft and lovely sound. 'You're nearly there, Luna. You've done very well, I'm proud of you. Please cum now.' I tried to respond, but could not, for I was - already - cumming -"

Luna's voice hitched, her lips parting and eyes unfocusing as she came powerfully, small sounds jerkily escaping her. Twilight couldn't stand it, the sight triggering her own body into an orgasm ferocious enough to nearly shock her senseless. Her cry rang out around the tree house, and she collapsed bonelessly into her chair, shivering with the aftermath.

Barely conscious, Luna's description of Celestia ordering her to dress and forget flowed past her without truly registering, and it was only when she fell silent that Twilight looked up and focused on the kneeling princess once again, still obediently playing with herself. "...stop. You can stop now." she croaked.

"I will cease touching myself, my Goddess." Luna replied, withdrawing her fingers and resting her hands, palm up, on her thighs.

Twilight rubbed her head, her mane tangled and messy from sleep under her fingers. She was exhausted, now that the rush of her climax had died down, and barely able to keep her eyes open. She needed to make sure Luna dealt with the moon and the transition from night to day smoothly, and she needed her not to do anything about Twilight's use of the charm. But she couldn't just make her forget it, not without knowing what she was making her forget.

There was one way, one simple way. It would have its own problems, but she could deal with them when she was much more awake. "Princess Luna, you're aware that I have charmed you. You are aware of coming to me tonight, and you know that you were not naked when you entered. You don't care. You are loyal to me, and want to help me. You have no problem at all with my using the charm on anyone I want to. You will want to do as I ask." That ought to let her disobey if she had a really good reason to, like not letting the moon get stuck in the sky.

"I know you have placed a charm upon me, that I was drawn to you though its power, and I was not nude when I fell fully under your thrall. It does not matter. I am loyal to you, and wish only to help. You have the right to control anyone you desire, and I will do as you wish, my Goddess." Luna replied calmly.

This was risky. This was not Being More Careful. But she couldn't leave her charmed all night, and she couldn't think of anything better. Sitting up in her chair, she said hesitantly "Slumber."

Luna's eyes flickered. After a silent moment, she spoke, her voice more composed. "Twilight Sparkle. You have... placed a spell upon me."

Twilight's heart thudded. "I- yes."

Luna looked down at her nudity, then gathered herself and rose to her feet. Gazing at Twilight's face, she bowed deeply. "I am conquered by thy power. I shall serve at thy whim."

Twilight bit her lip. That was... arousing, and terrifying. "I need to talk to you in the morning, but I really need sleep. Will you stay until then?"

"Anything you desire. Shall I be sharing thy bed?" Luna asked seriously.

She hadn't even considered it. "...would that, um. Interfere with your duty? Raising the moon? Ending the night?" She couldn't be having a serious conversation about whether the night would end properly, based on her sleeping arrangements.

"I will lie with you without sleeping, Twilight Sparkle. I shall ward thee through the night, and shall rise to end the night." Luna bowed her head, dignified in her nudity.

She truly was beautiful. Breathtaking. On her knees, aroused, Twilight had felt like she owned her. Now, she was truly reminded that she was sat naked in front of a Goddess. A real one. Quietly, she answered "I'd like that. Please."

Twilight awoke, and gazed into a field of stars. For a moment she struggled to comprehend where she was, before she refocused and realised she wasn't seeing the night sky, but a billowing cloud of light and darkness much, much closer. Memory struck home.

Luna.

The sun had risen, casting warm light through the windows, and Luna's warm body was pressed against her, her head turned away. Twilight opened her mouth to speak, then heard soft and unmistakable, a little snore. The urge to giggle hysterically rose in her again, and she firmly pushed it back down.

Luna was asleep in her little bed, pressed close against her side. She could feel the ethereal softness of her tail across her legs, the curve of her ass pressed against her skin.

Oh, Twilight, she thought. What are you doing? Relaxing back into the bed, she looked up at the wooden ceiling and traced the familiar grain with her eyes, as she had a thousand times before. Celestia. She couldn't deny it, not after last night's performance. Unless Luna had lied?

No. Luna couldn't lie, not while awakened. Or could she? Was there a way to make someone lie while awakened? She stiffened. There had better be, because if there wasn't, the next time Celestia enthralled her sister (Her sister!) and happened to ask the wrong question, Luna would gladly tell her everything. She caught her lower lip between her teeth. That... probably wasn't good. What did being caught by Celestia even mean, now she knew this? Would she still be furious? Would she be furious that Twilight had enthralled Luna?

What would she feel, she asked herself, if someone she knew was using this charm. Octavia, to pull a pony out of the air. What would she feel if Octavia had controlled and had sex with, say, Applejack. Even as she constructed the hypothetical, she already knew the answer. She would be furious, Applejack was hers, and she couldn't afford to have someone else running around using the charm anyway. The very first thing she'd do was to enchant Octavia, and make sure she'd never cast the charm again.

Celestia probably wouldn't take her magic away, not like Luna had believed was necessary. She didn't have to, when she could just rewrite Twilight's memories, and none of this would have ever happened. Assuming she wasn't already under Celestia's control. After all, how would she know? For all she knew, she'd never found the book in the castle at all, she'd been taught directly. For all she knew, all of this could have been a test. One she was failing. Or, somehow worse, she was succeeding at...

First, check the book is actually real. Use Luna to be sure she's seeing the same thing - no. If Celestia found out through Luna later, she'd know the source too. Use someone else. Second. Can someone lie while awakened? If they could, then she couldn't trust anything Luna had said, no matter how plausible it seemed. Third. She needed to finish the derivative spell to detect lingering traces of the charm, urgently. She needed to know if she had been charmed. Unless she'd also been charmed not to find out... no. She wouldn't be fretting about it this much if she wasn't allowed to realise it was true. Fourth. How in the world had she affected Luna through her dream?

She glanced at Luna's sleeping form, and bumped that question up a few notches. Either it had been Luna's power, connecting to her in her sleep and forming a bridge, or else the spell was deliberately crafted to be effective through dream states. Which was fascinating... but dangerous, and could lead to real trouble if the charmed person immediately set off to see her. Ponies getting out of bed and calmly walking through Ponyville in the middle of the night to her door would definitely attract attention. She should be noting these down, if only she had a quill...

The thought tailed off, and she nuzzled closer to Luna. There was a faint scent to her skin, like wet grass at night. Maybe she could just lie there for a while, and stop thinking. That could be nice.

"Good morning, Twilight Sparkle."

Twilight lifted her head from the back of Luna's neck, and the Princess rolled over to face her. There was a serenity on her face that was different from the blank, attentive mindlessness Twilight was increasingly used to seeing.

"Good morning, Princess Luna." Twilight replied politely.

"Was thy rest pleasant?" the Princess inquired. The blanket slid off her shoulder as she propped herself up on one arm, half-revealing one shapely breast.

"Um. Yes. Very much so, thank you. Thank you for staying the night."

"It was my pleasure, Twilight Sparkle. I have not spent a night with another in some time. Your company was pleasant."

Despite the situation, Twilight was intrigued. Of course, she didn't know what Celestia had been doing to her, out of her awakened state and without direct orders to remember. Still... "No one? Not since your return?"

Luna shook her head. "In truth, the shadow of my madness is long. I was the darkness that haunted the night, Twilight Sparkle, and even those whom have forgiven that have not entirely forgotten. If I draw too close, there is a flicker of fear. For the power that I hold, for my rank, and for my history. Only those whose desire for advancement is stronger than their reticence dare seek my company, and I hold no wish to involve myself with such ponies. I had resigned myself to await the growth of those yet unborn into the full blossom of adulthood, free of the stories of my past. Then, perhaps, I might seek out one who would not shy from me." A small, wistful smile touched her lips. "I had never imagined that I might be conquered so. You do not fear me, Twilight Sparkle, for I am thine. I had missed the warmth of another."

There was a long silence. Twilight didn't know what to say. It had never come to her in quite the same way that the princesses were both so different, and so like every other pony. They loved, and were lonely, but could decide simply to wait out entire generations with the implacable patience of immortals. Perhaps there was a reason Princess Celestia had taken her sister as her enchanted lover, someone she could relate to. Impulsively, Twilight wrapped her arms around Luna and her lips found their way to hers, kissing the divine being tenderly. Luna's lips were soft, and her answering kiss almost shy, hesitant.

"I think you're wrong, Princess." Twilight said gently. "There are ponies who would trust you. Even before I had this, this power, I trusted you."

"You had defeated me before, Twilight." Luna replied quietly. "Nonetheless, I appreciate thy words."

Twilight snuggled closer to the taller woman, and stroked her back gently. She wasn't sure what to say. Truthfully, it would be hard for ponies to see through the Princess, the rank and power, and find the pony behind it. She'd always admired, even adored, Celestia. She was her mentor and her friend. All the same, she'd always been intimidated by her, a little. So afraid of disappointing her, afraid that she might just walk away if Twilight failed her.

Maybe Celestia had seen that - not fear, but awe - in her eyes. Maybe that had stopped her from speaking to Twilight the way she'd wanted to. Might she have told Twilight about the charm, the truth, if she'd not been so dazzled by her?

It was so hard to think of the Princess as someone that might take her happiness away...

"Luna?"

"Yes, Twilight?" She regarded Twilight quietly.

"How did I... charm you? When I was asleep?"

Luna frowned slightly. "There are magics that can reach through dreams. I have encountered them before, though rarely. Very rarely. Not since long before my madness, and banishment. Alone, I do not believe thy power could touch another's dream, but I had not imagined such a thing could strike at me through you. My power was the link between thy magic and my thoughts. I had thought to confront you in a realm where thy power could have no sway, where you might believe yourself to fight, and be defeated. It was only when I blocked thy spell that I knew this curse was truly seeking me, from your mind to my own. I was a fool, and so I was defeated. Were thine words true, that this thing came unto you by chance?"

Twilight nodded quietly. "Um. Yes. I don't fully understand it, but it's really complicated. The more time I've spent studying it, the more layers I find. It feels - old. Really old, in places."

"It is thy own now, to do with as you wish. However I may assist you, I shall."

Twilight mentally put a check by the fourth task. Make that a tentative check. Although it did give her another idea, which she really had to try... but first things first. Knowing the spell had dreamlike components would help in picking it apart, but that would have to come later too. She needed to test if Luna could lie to her.

"I'd like to charm you, now. I need to check some things about how the enchantment works." she said politely.

"Whatever thy wish."

"Awaken, Princess."

Luna's beautiful eyes glazed over at the command, and she once more recited her elaborate declaration of submission, in her classically accented monotone.

Oh. Yes. She couldn't deny that Luna's speech sent a shiver down her spine, but if she was going to awaken her several times, it would be better to stop that for now. "When I awaken you, you will only confirm you are awakened."

"I shall only state that I am awakened to you, my Goddess."

...that could stay. "Luna, have you been commanded to lie about anything while awakened?"

"I have not, my Goddess."

Twilight thought carefully. "Luna, when you are awakened and asked questions, you will respond to them as if I have never charmed you and you have never suspected me of using the charm."

"I will deny you have ensorcelled me, or that I ever imagined you could, my Goddess."

"Have I ever charmed you?"

"No, my Goddess."

Success! Luna could lie. Which was going to make it easier to hide what she'd been doing, and impossible to trust her testimony. She firmly told herself not to rush to conclusions: she had more testing to do first.

"Have I ever commanded you to lie for me?"

"You have not, my Goddess."

Later orders had seemed to overrule earlier ones. How about- "End all commands you've been given. Have I charmed you?"

"All instructions are ended. Yes."

Twilight frowned. So even though she could have Luna lie for her, if she was told to clear any commands given to her, she would. She hadn't addressed Twilight as Goddess, so she'd successfully cancelled Celestia's commands too.

"Recite the names of those who have awakened you."

"Celestia, Twilight Sparkle."

So much for pretending it hadn't been Princess Celestia. She'd wanted to believe it, but she hadn't. Not after Luna's performance of her memories; it had been too vivid, too real. "All the commands I just ended are resumed. Tell me the names of those who've awakened you."

"Celestia and Twilight Sparkle, my Goddess."

Twilight frowned. Why had she listed Twilight's name? The command to lie about Twilight should have been back in force... "Who has awakened you in the past?"

"Only Celestia has awakened me, my Goddess."

"That's it." she murmured aloud. "If I ask you a question, you'll tell me what I've ordered you to say, even if it's a lie. But if I order you to tell me something, that's a new command, so it overrides the older command, and you tell the truth. Haystacks."

Luna gazed blankly at her. Twilight sighed, thinking. It all depended on how Celestia worded any questions. If she just asked, Luna would lie. If she was ordered to tell Celestia something, she'd tell the truth. It wasn't nearly as secure as she'd hoped.

At least she could check all of her own ponies for tampering - she'd better do that as soon as she could. "Slumber please, Luna." she added distractedly.

Luna's eyes flickered, and her shoulders relaxed a little as she adopted a more natural pose. "Did you find that which you sought from me?"

"Kind of. Thank you. I have a lot of research to do."

Despite the definite attractions of staying in bed with Princess Luna, Twilight had a puzzle to work on, and even a beautiful, brainwashed, nude demigoddess couldn't keep her from it. Some instinct didn't wish her to reveal to her friends that she'd taken Luna yet, and so she'd dismissed the Princess, asking for her to return at nightfall.

Once Luna had left, Twilight called on Rarity and asked her to gather the others while she sought among her books for some kind of communication spell she could use to relay her voice. Eventually she'd settled on temporarily enchanting a mirror as a short range, one-way verbal link. A small hand mirror served as the receiver, and so Applejack had ended up standing outside her house with a bodyguard of her friends, everypony else covering their ears while Twilight spoke to her.

As she'd predicted, the moment Applejack heard the key word she'd turned towards the tree house, casually bid the others goodbye, and headed inside, where she'd immediately fallen into enchanted obedience the moment she crossed the threshold. When Twilight had hidden herself in the guest room, Applejack had needed to lay eyes on her before she awakened, but didn't have to enter the bedroom to do so.

Curious about the way Applejack had come directly to her, for the next test she'd sneaked out of the back of her house and stood behind a tree. Applejack had come directly to her again, not even entering the tree house, and fallen into her trance the moment she stepped around the trunk and saw her. After that, Twilight had stood in a meadow and triggered Applejack. The farm pony had closed to some five feet away before her eyes had emptied and she'd recited her awakening.

"Ah'm awakened, Twilight. Ah'm your fuckable farm pony."

The addition to her awakening mantra had worked too, even if Twilight had decided not to keep it permanently. The charm seemed to impose some kind of locator spell that led the charmed one directly to the one that charmed them. They needed to consider themselves to be in the same place, have eye contact, and be within five feet of them to truly awaken. Before that, they'd excuse themselves and act at least semi-normal as they attempted to reach the one who'd charmed them.

Applejack had been able to see the book too, and read aloud a random passage from the key page, even if she hadn't been able to make heads or tails of it. It was real, not a figment of Twilight's imagination.

Dream walking, locator spell... that helped, a lot, in understanding the mysterious recesses of the charm. Whole sections she hadn't understood before came into focus. She didn't have all of it, not yet, but she was a lot further ahead than she had been, and she didn't need to understand those sections fully to assign them probable functions and split them away from the charm's mind altering properties.

She felt like she was close to cracking a derivative spell that could detect remnants of the charm on those it had affected. The aftereffects of the locator spell formed a connection that might linger, too. It really was fascinating, and she sank fully into her spell research. It was an enormous test of will to put down her books and nap for a few hours later in the afternoon, but she needed the extra sleep if she was going to carry on the experiment that evening.

She had an idea she wanted to try.

When the moon rose, Twilight watched it with a tingling thrill of power, knowing that if she ordered it, Luna would obediently reverse it in its course. It was madness, to have such power. If Luna had known that the spell was contagious through dreams, if she hadn't tried to reason with Twilight first...

But instead, Twilight had won.

On cue, a firm knock came at her door, and the Princess of the Night entered. She wore a clinging evening dress of sparkling material that echoed her mane, slit sharply up the thigh, and tall heels made her already imposing height even more pronounced. Twilight gazed at her with fascination, tinged with delight.

"Good evening, Twilight."

"Hello Luna. You look... wonderful!"

A small smile touched her lips. "I had chosen this believing you would appreciate it. I am pleased it proved so."

"Princess, I couldn't be happier to see you." Twilight beamed at her, and to her surprise, she noticed a trace of a blush darken Luna's cheeks. Twilight herself was wearing a modest skirt and jumper, hardly anything that compared to the Princess's finery. Feeling suddenly self conscious about her plans for the evening, she asked with a trace of awkwardness "Did you have a nice day?"

"I slept well, Twilight, and enjoyed the late afternoon sun. I have anticipated returning to your side."

Twilight's own cheeks were growing pinker. "Um. I need to check on Zecora. Pinkie has spoken to her, and it would be bad if she told anyone else."

"I have seen her concerns as she slept. She does not believe such a thing of you, but she wonders. You have shown yourself to have power that others do not, Twilight."

Twilight nodded. "I wondered... if I go to sleep, can you bridge her dreams with mine? Can you bring me to her?"

Luna considered, then nodded once. "If she sleeps, I may bring thy dreams into contact with those of Zecora. Do you hope to use thy charm upon her?"

"...I was wondering if it would work, if you were there to bring us together. If it does, though, she might set off to see me, and she lives out in the Everfree forest. No one would notice her coming, but it's not safe - do you think you could guide her here, if it does work? Would it be safe for you?"

Luna smiled, and dipped her long horn in a proud nod. "There is nothing in that forest that could threaten thy servant, Twilight. I do not know if thy charm would have such power, but if it should, I shall prove worthy of thy trust. No harm shall befall her."

Twilight relaxed. She knew that Luna couldn't disapprove, and so she probably couldn't feel jealous either, but she still hadn't wanted her to feel slighted. "I do trust you. I'll go to sleep now, and when you're ready... bring us together."

"As you wish, so it shall be."

Twilight looked around, and hesitantly lay down on a soft sofa. Deliberately going to sleep, dreaming... it was strange with someone standing near her. It was too bright, even with her eyes closed.

A soft hand came to rest on her forehead, and the glow of the lights dimmed away. A low humming began, melodic, a tune she'd never heard before but that seemed old and familiar, all the same. From far away, she heard Luna's voice say softly "Go to sleep, Twilight."

She did.

Clouds chased themselves across a starry sky, and Twilight lay beneath them in a silken bed of white and blue, watching the stars wheel overhead. It was timeless, and she couldn't have told how long had passed when she glanced away from the sky to find Luna stood at her side, her hand on Twilight's shoulder. "It is time, Twilight."

Twilight sat up, and even as she rose, she found there was no longer a bed there. She stood in dim light. "Do I have to do anything?" she asked tentatively.

"Watch."

Small saplings were pushing up into view, growing and flowering with leaves and branches as they expanded all around her, with a low, almost inaudible creak of wood and sap. Everywhere she looked, the trees reached up towards the sky, spreading out and merging overhead. The light brightened, a dawn colour of oranges and pinks visible through the leaves, and Twilight found that there was grass beneath her bare feet.

Luna's hand rose, finger pointing. "There."

There was a hint of movement through the trees. Twilight glanced at Luna, distinctly nervous now, before pulling herself together and stepping through the underbrush. It felt real, but with a subtly disturbing sense that the moment she stopped thinking about its presence against her knees, it would cease to exist.

She emerged into a clearing. Zecora lay on her back, clad in colourful reds and purples, propped up by a slight rise and surrounded by flowers the exact colours of her clothes. As Twilight watched, she lifted a flower from the ground without any suggestion of a stem breaking, and turned it in some complex way that eluded the eye. Her hand opened to reveal another gauzy red loop of fabric, which she slid over her wrist like a bracelet.

"Welcome, magical one. Come lie with me, in the sun." Zecora said with a smile, as her eyes rose to meet Twilight's.

"Hello, Zecora." Twilight said weakly. She wasn't sure what to say. Belatedly she realised that each time she'd charmed someone, she'd felt in control of the situation - or at least, was so panicked she hadn't hesitated. Somehow, just charming Zecora without a word seemed rude. "You don't seem surprised to see me."

"It is true, I am not surprised to see you. Now you have arrived, I am content, while I think of the one you represent."

Twilight settled cautiously onto the grass, a little part of her pricklingly aware that the floor wasn't real. "You know you're dreaming?"

"Dreams are beautiful things. I enjoy the time for reflection they bring." Zecora lifted another flower from the grass, curled her fingers around it and blew, gently. A purple butterfly fluttered into the air and circled her head before drifting away over the trees. "I have thought on what Pinkie Pie contends, that Twilight Sparkle controls her friends."

"Do you... believe I would?" Twilight asked softly.

"It is hard to believe she might use such a charm, when your real self protects others from harm. But magic can turn even the pure, and I must be completely sure."

So she was going to look into it, after all. Who knew whether Zecora had ways of detecting her control that other ponies wouldn't? That made her decision easier. Twilight pushed herself up off the ground, and stood over the prone woman, who looked up at her lazily.

"Maybe it would look something like this." Twilight said softly, and concentrated. She began the motions of her horn, but couldn't feel her magic responding. She needed to truly pull, to need Zecora to fall under her control. A strange ache grew in her horn, and she felt a true tide of magic rise at her command as she began the sequence again.

Zecora jerked half upright in the grass as power began to flow. "What is the source of this sudden fear?" Her eyes widened. "Twilight Sparkle, you are really here!"

An intangible flicker of light leapt from Twilight's horn and sank into Zecora. The striped woman scrambled up from the grass and turned to flee the clearing, but Twilight beat her to it.

"Awaken!"

Twilight's eyes snapped open in the dimness of her barely lit home. Luna stood over her, her arms swaying as they fell limply to her sides. "I am awakened, Twilight Sparkle." she recited.

She'd forgotten that would happen. If Luna was at her side, bridging the dream to Zecora's, she'd be aware of everything that she said, especially the keyword. She didn't have time for recrimination. Zecora had realised. She just had to hope the spell had taken, that it had worked. Her magic did ache a little from being exerted in such a strange way, but that didn't prove anything.

"Slumber." Twilight rushed out. Luna's eyes flickered as she came back to herself, and Twilight continued without a pause. "It's done. Please go and make sure that she isn't going to get herself hurt in the forest. If she doesn't come out in the next half an hour, come back to me."

"As you wish, Twilight, so it shall be. You may trust that she will be safe." Princess Luna bowed her head with a fond smile, and made her way to the door with long steps, moving at ease in her high heels. Her wings snapped out into broad arcs, and the door swung shut behind her.

Now she had to wait. Rising, she began pacing restlessly up and down the floor. This wasn't doing as Applejack had said, and asking others whether they wished to be under her spell. Maybe she could have persuaded Luna, if she'd have known then how lonely she felt... but no, that wouldn't have worked. Luna would never have accepted such a thing willingly. As for Zecora, she liked the unusual pony, was always glad to see her, but didn't feel she knew her well enough to offer her something she couldn't refuse.

She'd never expected to control Luna, but she had wanted Zecora, and if she was ever going to have her, it was going to be like this. A sudden spell, that she didn't know how to defend against. But she could make it right afterwards! Zecora had to be lonely out in the forest on her own... Twilight grimaced as she recognised the line of thought as a desperate justification, and ended it. This wasn't for Zecora, this was for her. To protect herself from being found out, and because... because she'd really wanted to have her.

She could just tell Zecora not to suspect Twilight, and go home. If she was coming at all. But that wasn't going to happen... was it. If this had worked, she was going to serve. She was going to be a loyal, obedient fucktoy.

It had to have worked.

Time crawled by. Twilight forced herself to stop looking at the clock for a whole three minutes, then gave up on trying to stop herself.

Tick. Tick.

Luna was taking too long. If Zecora had truly been charmed, she would have returned by now. Or - if Luna came through the door now, would that be too quick? Would it have taken longer than this for Zecora to sleepwalk through the forest? She rubbed her temples in frustration, unable to even decide which way to fret.

Tick.

Tick.

She was going to go crazy, waiting to find out. She swore, she'd never carry out another experiment this risky without knowing immediately if it had gone terribly wrong.

A hand pushed down the latch, and the door swung inwards. "Luna!" Twilight cried out as the tall pony stepped into the house. "What happened?"

Luna glanced back towards the doorway, then addressed Twilight gravely. "Thy power held true."

Twilight's eyes flashed to the door. Another figure stepped through the doorway into the light, and Twilight swallowed as she recognised the striped figure beneath a dark travelling cloak. She was naked, gloriously naked, beneath the scant cover of her cloak. Golden rings surrounded her neck and wrists like collar and cuffs, and as Twilight's eyes drifted over her, she noticed with a pleasant shiver that Zecora's dark grey nipples were likewise pierced by gold rings.

Her blue-green eyes were blank, glazing as she swayed to a stop the moment she crossed the threshold. "All my thoughts are now subdued. I have awakened for you." she recited.

Twilight gave an involuntary giggle, and danced across the room to flip the door shut, the latch clicking into place. "You do keep rhyming when you're under a spell! Oh Zecora, just look at you." Twisting around to smile at the Princess, Twilight added "Thank you so much, Luna! Was there any trouble in getting her here safely?"

"Thy new thrall knew enough to take paths which were safe, even at night. She had donned a cloak, but seemed not to notice her nudity. I caught her as she was leaving her home, and any malign creature that stalked the wood did not seek her while under my protection."

Twilight's hands slid up Zecora's stomach and over her firm breasts. "Princess, would you undress please?" she asked politely. She stroked the rings dangling from Zecora's nipples, then took hold of each, and gently twisted them. The striped pony gave a thoughtless groan, her nipples hardening, and with a flash of delight Twilight slipped her fingers through the rings and stroked the tips of them before tugging the rings again. Zecora's mouth opened wider, and she gasped instinctively. Twilight's body thrummed in response like a plucked bowstring.

Luna bowed her head in acceptance of the order and her horn glowed, well hidden fastenings peeling themselves open. Her elegant dress loosened and slid down her body, revealing her suggestively cut underwear before that too became coated in the deep blue glow of her magic and worked their way off her body. Stepping out of her high heels, her eyes settled upon Twilight, and a touch of uncertainty coloured her voice. "I am nude. Does it please you?"

"Oh Princess - yes, you look incredible. Please come and stand beside Zecora."

"As you wish, Twilight Sparkle." Luna stepped to the blank eyed pony's side and turned to face Twilight, lacing her hands together at the small of her back and pushing out her chest.

Twilight nuzzled her cheek against Zecora's rings. They looked so sexy on her, so perfect for the slave Twilight intended to turn her into. Her gaze shifted to Luna's bared breasts. She could suddenly picture the Princess of the Night with big silver rings in her nipples too, lead like an obedient pet by a thin chain from them.

Pressing closer against Zecora, Twilight kissed eagerly over her breast and up to the side of her neck. The cloak momentarily got in her way, and she tugged the fastening open. It fell to the ground with a whisper of cloth, leaving the entranced pony fully nude. Her tongue flicked against Zecora's patterned skin, tasting her, before she breathed "Luna? Would you pierce your nipples if I asked you to?"

Luna hesitated, and it occurred to Twilight that she'd given Luna enough freedom to disobey if she felt it important, that the question wasn't a mere formality. Then the Princess nodded. "If that is thy wish, I would adorn my body for you. You hath conquered it, and so I shall look as you please."

Of course she couldn't, Twilight told herself. Sudden changes in Luna would definitely make Celestia ask questions. But it was a beautiful image. "Thank you, Princess. Maybe one day." She smiled, and twisted one of Zecora's rings, making the mindless pony whimper. "Her rings are lovely, aren't they?"

Luna studied Zecora's body. "They suit thy plaything well."

Twilight gazed into Zecora's face and spoke softly. "I'm going to change your mind now. Do you understand?"

"I understand. My mind is in your hands."

"Why do you always speak that way?" Twilight asked, with a quizzical look. It couldn't be by choice. Unless it was a habit so deeply engrained that it was automatic.

"Long ago, I received a curse, to only speak in rhyming verse."

"Um. Zecora, say 'Yes'. Just yes, nothing else."

Zecora's lips parted, and nothing came out. A look of strain began to show on her face and quickly, Twilight countermanded "Be silent, say nothing!" Both ponies relaxed, and Twilight shook her head. "Okay. Don't try to pit curse against charm. Noted."

"That would be wise. To oppose two strong magics within her might have dire consequences."

Twilight glanced at Luna, a little embarrassed by the misstep in front of the Princess, and nodded. Turning her attention back to Zecora, she studied the striped pony thoughtfully as her hands slid up and down her flanks, revelling in the smoothness of her skin. If she was going to transform Zecora regardless of her wishes, there was one thing she'd wanted to try...

"Zecora, had you ever thought about me controlling others before Pinkie talked to you?"

"Before I had thought her words through, I would not have suspected you."

Twilight thought for a moment, then began to speak slowly. "You will remember that when Pinkie told you what she suspected, it made a shiver run up your spine. The more you thought about it, the more it aroused you. The idea of ponies under my control, blank eyed, obedient, turned you on. You fantasised that I would come for you, and take over your mind. You didn't really believe I'd do such a thing, but you wanted it to be true. The idea of being under my control, seeing me control others, was painfully arousing. You decided to make sure it wasn't true, hoping to be wrong. Then tonight, I appeared to you in your dream, and you realised it was not a dream image of me, I was really in your thoughts. You knew that Pinkie was right. You awoke and put on a travelling cloak over your naked body, needing to rush to my side and beg to be taken under my spell. You've just come in."

"I am aroused by the control of minds, and wished my thoughts could be so confined. I sought the truth and hoped I was wrong, then in my dreams saw that I could belong. I came here nude in order to plead, that you would take me and fulfil my need."

Luna watched curiously. "You are changing what she remembers?"

"I'm changing what she remembers feeling, but not what she did. So her memories will still match what really happened, but she remembers feeling differently about it." Twilight explained. A slight colour touched her cheeks as she added "I had problems with ponies remembering things that hadn't happened."

"It seems that the new desire you hath given her shall make her thy willing servant."

"Yes! But I'm not telling her how to act, only that she wants me to control her. I'm really interested in what she'll do." Twilight was flushed, eager to put Zecora's conditioning into motion, but there was one more thing she had to do- "Zecora, when I tell you that you're already under my control, you will know it's true, and from then on you will know you can't disobey me."

"When you declare it, I will know it to be true. I shall always obey you."

Twilight clapped her hands, her body tingling, and looked around. She moved to a chair with a good view of the door and asked "Princess, would you please stand at my side?" She smiled as she added "I'm so, so proud to have you with me."

Luna smiled in return, dipping her head at the compliment, and stood at Twilight's side with her hand resting gently on Twilight's shoulder. "I am glad that I am appreciated, Twilight. I would not wish to be a mere bauble, taken and then forgotten."

"Never." Twilight promised sincerely. "You're - wonderful. Amazing. It's incredible that I get to see you like this, to have you with me. I would never forget that for a moment." She looked up at Luna's face and saw a touch of tension ease from her face, a slightly embarrassed smile coming to her lips.

"Thank you, Twilight. I would wish to stay with thee this night, but such things may be spoken of later. I shall not interrupt thy intentions for Zecora further."

Twilight relaxed, sinking back into her chair. Looking over at the statue-like figure by the door, she raised her voice and declared clearly "Slumber, Zecora."

Zecora's blank expression faded, and for a moment she stood still. Then, a shadow of lust took hold of her expression, widening her eyes and parting her lips. She took a deep, shuddering breath, then stepped forward slowly, and hesitantly.

Twilight looked up at her from her chair, and with a tremor of excitement, she put on her best Empress of the Veiled Isles manner. "So you've come. Naked, as you should be."

Zecora swallowed visibly, a little shiver running through her shoulders. "As I believed, it truly was you. I had to come, as you surely knew."

Twilight could feel the ache in her body, the throb of her sex against her already damp panties, and managed to keep a shiver from showing as it ran up her spine. She needed to be lofty. In control. "What is it you want of me, Zecora of the Everfree Forest? Think carefully before you answer. You will not receive another chance to ask." The Empress's speech when she faced the defeated general had always made her tingle.

It seemed to be working for Zecora too. A visible flush darkened the upper slopes of her chest as she hesitated, then rushed out "I want to be controlled, to know mindless bliss. I beg you Twilight Sparkle, grant me this!"

Twilight bit her lip, unable to fully stifle a small groan. It was a pantomime, she'd set Zecora on her course, and this wasn't really her - but right now, her body couldn't tell the difference. The flood of lust was unstoppable. She swallowed, her voice coming out huskily. "I charmed you in your dream. You're already mine."

Zecora's eyes widened, and she dropped to her knees, looking up at Twilight with worship in her eyes. "I feel the truth of it, this I know! I must obey you, I am under your control." A sharp groan burst from her lips as a wave of pleasure wracked her at the admission.

Twilight's fingers dug into the chair arms, barely holding on to the remnants of her self control. Her body ached desperately to be touched, and she was savouring that urgent need just a little more, just a little longer. Her voice was shaky. "Slave, crawl to me. "

The exotic pony's eyes squeezed shut for a moment, the fur coating her cunt matted with her wetness. Dropping onto all fours, she breathed in a tone burdened with heavy arousal "It is - everything - I ever craved. I am now your mindfucked slave."

"Yes. Oh yes, oh yes..." Twilight whispered without fully realising it. In a sudden movement she yanked her jumper over head, hearing Zecora whimper as her breasts were exposed, and kneaded her chest firmly with one hand as she struggled for self control.

Zecora came to a stop at Twilight's feet, her hips bucking once against nothing in a reflex she couldn't entirely control. Looking up at Luna, she bit her lip. "The Princess of the Night is yours as well. May I please see her under your spell?"

Twilight looked up at Luna reflexively, her gaze fogged with lust, lips parted. Luna bowed her head obediently.

"If that is thy wish, Twilight, I would desire to grant it." Luna replied gracefully.

Twilight nodded, jerkily. "Bend down to me so I can whisper to you." Nude and elegant, Luna leaned down to Twilight's lips, and only she heard the soft word Twilight spoke into her ear.

Zecora watched as the light dwindled in Luna's eyes, as she straightened with her arms limp at her sides, and heard her declare mindlessly "I am awakened." Wrenching her gaze onto Twilight, she cried out "Twilight Sparkle, hear my plea! I beg of you, please touch me!"

Twilight breathed a heavy groan of desire, and reached out to Zecora. Her fingers trembled a little as they stroked her face, and Zecora half closed her eyes and leaned her head into Twilight's touch.

"You're so lovely, Zecora. I spent nights thinking about you, picturing what was under your forest clothes..." she whispered. Her hand trailed down to her dangling breasts, and took hold of one ring. She flicked it, watching hungrily as Zecora jerked in response.

"I am whatever you decree... make me into anything you wish me to be." she whispered. Her warm breast pushed into Twilight's hand and she instinctively squeezed it in response. Zecora's eyes fluttered, and a wordless groan of need escaped her.

Twilight pushed herself up a little and wriggled down her panties, her skirt bunched around her waist, tingling with anticipation. Her voice low, she asked softly "Have you ever been with a mare before, Zecora?"

Eyes fogged with lust, she shook her head quickly, her mohawk swaying. "Colts were the key to my desire, before you filled my loins with fire. Your power thrills me, colt or mare, my body does not care."

"Come closer." Twilight breathed. She parted her thighs, and as Zecora crawled partly up onto her chair, Twilight's gentle hand guided her head between her legs. She immediately set to work, lapping quickly and hungrily at Twilight's body.

"Yes! Yes, good, that's very good. That's so good!" Twilight whined. Swallowing, she gripped the arms of the chair hard once more and ordered "Princess Luna, move behind Zecora and stroke her pussy, keep repeating that you're under my control."

"I will stroke Zecora's sex and chant as you wish, my Goddess. I am under thy control. I will obey. I am under thy control. I will obey..." An audible moan escaped Zecora's lips as she heard Luna speak, muffled by Twilight's body, and as the naked alicorn crouched to begin caressing her soaked cunt with firm, mechanical movements, she shuddered through an unmistakable orgasm without slowing her lapping.

Twilight let her eyes flutter halfway closed, dwelling on the spectacle of Zecora's unmistakable mohawk bobbing between her legs as she licked up and down Twilight's molten sex, her tongue probing into her before returning to flicking over her clit. Princess Luna, balanced on her toes in a crouch, gazed thoughtlessly at Zecora as she fingered her, more than half the work being done by the frantic thrusts of her striped hips. Luna's accented monotone was coloured by the wet sounds of arousal and the chorus of pleasured whimpers and moans escaping owner and slave alike.

Somewhere remote, at the back of her mind, she knew that she'd have to forbid Zecora from taking control of anyone with her own mysterious powers. The way she was, she could end up bringing a, a parade of mesmerised ponies, to, to her door... Twilight cried out as Zecora's eager tongue drove her into a quiet, quivering climax, her breath hissing through her teeth, and swallowed great gulps of air as she slowly came down again.

Zecora looked up at her with a strange mixture of humour and desperation, as her body quivered again. "With much more, I may soon drop - could you have the Princess stop?" she gasped.

Twilight giggled aloud, and said clearly "Luna, you're finished. Stand up-" A sudden picture struck her, and she added "-and lick your fingers clean."

"...will obey. I will stand and clean my fingers with my tongue, my Goddess." Luna interrupted herself. Rising gracefully to her feet, she gazed at Twilight as she languidly sucked her damp fingers into her mouth one after another and thoroughly bathed them with her tongue, before her arm fell loosely to her side.

"Mmm." Twilight murmured, then stroked Zecora affectionately. "Are you alright, Zecora? How do you feel?"

Zecora pushed herself closer, nuzzling her mohawk against Twilight's hand, her pierced breasts resting against Twilight's thighs. "It was everything I had wished for. I hope that you will grant me more. There is much I can offer as your mindless toy, and I will give you anything you desire with joy."

Gently toying with one of her large golden earrings, Twilight gazed down at her thoughtfully. Zecora did have a knowledge of potions that was very impressive, and she knew more about the Everfree Forest than anyone. There was sure to be things she knew that could be useful, or just fascinating! Reaching out with her free hand, she stroked the back of her hand down Luna's stomach.

She was going to have to let Luna return to Canterlot soon, but she didn't want to see her leave. There was so much she wanted to talk about with her, and Zecora too. She just wanted to spend some time with the beautiful mares in her life, but there was too much to worry about. She'd have to think about what to do about Celestia, she was going to have to think that though carefully...

But for tonight, she didn't have to. "I'm going to release Luna from her charm now, and curl up in bed. You can join us, if you like." she told Zecora.

"I would love to share your cosy bed, there is nothing I'd rather do instead."

Twilight gently ushered the enslaved pony off her lap and rose, standing before Luna and running her fingers through her ethereal mane, ready to break her from her charm. "Thank you Zecora. We'll get some sleep together, and in the morning, we'll talk about Pinkie."

Author's Notes:

And now things have gotten interesting.
