That night, Luna raced through her few official tasks and spent the remainder of her time fantasizing, role-playing, and furiously masturbating as her controlled passions boiled over. Ambitions for romance and tender lovemaking were pushed to the far rear. Luna imagined Celestia both wrapped around her finger and screaming in ecstasy beneath, fucked in mind and body. She played out a scenario of utterly conquering Celestia that very evening, going from ticking clock to licking mouth at Luna’s pussy, eyes spiraling as Luna dangled a pendant before them. ‘Obey, slave,’ and ‘Yes, mistress.’

A fantasy. Even if Luna’s delicate trance could have survived the jarring suggestion of sex, it could never have endured the frenzy she craved. Her hooks were in the subconscious, yes. But ponies ignored their subconscious every time they woke up before dawn or stood ground against their fear. Influencing the instinct only got you so far, and Luna wasn’t even sure how effective that had been.

Three frantic orgasms left her with the drained feeling of too much, too fast. She sprawled upon the bed at the end of it spread-eagled, letting the night air brush against her sweat like a douse of cold water.

Her passions had gotten their fun. Now it was time again to think.

Luna eyed her own body with approval. She had long moved past all self-conscious doubts: she was gorgeous. Small breasts with blackberry nubs, each no bigger than a curled fist but perky and smooth. She was quite slim, taking after the pegasi with lean muscle and a tight, aerodynamic ass. A more athletic model of beauty than her voluptuous sister, but no less glorious. Different, yet the same. A worthy equal.

Black night turned to purple as the time drew near for Celestia to raise the sun. Luna stood and showered, barely feeling the water as she pondered her accomplishments and plans.

Secrecy remained paramount, although Luna would have to make greater and greater plays. Celestia would not know her subconscious was changed, even as it influenced her thoughts. The magic on her ring was as careful and gentle as could be done. It only affected the wearer, securing Luna against strangers falling to the charm, and it prodded the subconscious more than the conscious. If unpressed, Celestia might idly watch the blue moon and think lovingly of Luna. The sight would reinforce Luna’s suggestions upon her subconscious, but Celestia would remain awake and clueless. And if Celestia was distracted or particularly alert, it would have no more hold than a hypnotist’s pendulum on a roller coaster.

In short, there would be no effect on her work. No way for Celestia or anyone to become suspicious. But what was the next step?

Luna took cold showers. The stickiness of the night’s adventures washed down the drain. Love was patient.

She turned off the water. The next step was obvious: find out if the first even worked.

Luna gave it a few days. If left alone, Celestia’s subconscious would correct itself. The ring supposedly helped keep her influence, as did the lavender wash Luna had the maids use when cleaning her sister’s sheets. Ultimately, though, the only way to learn if her suggestions held was to use them. Preferably in a natural way, because ‘Dear Sister, lick me out,’ was a gamble at bad odds.

Her time came when she reported to Celestia one morning, stopping by her room with random news from the Everfree. Casual with her sister and charmingly populist, Celestia always dressed herself and kept doing so as Luna made her report. A criminal fold-out wall separated them until Celestia emerged in a full-sleeved dawn-orange dress and subtle crown, ready for the day.

Luna watched carefully as Celestia walked barefoot to her bed and sat down, giving a curiously resigned sigh. Yellow magic floated over a pair of golden pumps with complicated laces, metal footrests, and toes pointed enough to stab.

Luna wore heels at social functions, but an inch high at most. She scoffed grumpily. “Oh, don’t torture yourself. Wear those nice silver slippers I got you. They’re plenty formal enough, and it’s not like you’ll be going outside today.”

“I must look my best.” Celestia gave a wry frown.

Luna’s mouth sighed. Her mind pounced. “Dear Sister, please wear the slippers I gave you.”

Celestia paused for a second longer than she might have. Luna fancied she saw the gears in her subconscious tick into place like clocks.

Trust Luna. Obey Luna.

Celestia wiggled her eyebrows, setting the foot-torture devices back where they came. “Alright, if it makes you happy.”

They chatted for another minute, but Celestia’s work had to begin. They departed and pleasantly went their separate ways.

Alone, Luna allowed a small frown to play on her face and gave a light ‘hmph.’

Celestia was beautiful, kind, all those other things, and very, very accommodating. Did she act as her hypnotized subconscious bid? Or did she just change her mind to satisfy Luna?

Luna pondered on her way back to the room. Another test was needed. A harder thing to arrange than she first guessed. It would have to be subtle so Celestia’s conscious mind didn’t revolt, yet also something she would not do normally even if asked.

There were delicate foreign matters Celestia managed without input, to be balanced by one steady hoof and no more. Luna could ask to replace her? No, of course not. Celestia was the diplomat of them. Luna would not fare as well, and no sex was worth damaging Equestria’s livelihood.

She could have cake with Celestia, and demand her sister’s slice? Luna smiled, but rolled her eyes. All jokes aside, of course that beautiful mare would give her the damn cake. And perhaps think her a bit of a brat. No sex was worth Celestia’s disapproval, either.

Luna mapped steadily through the diversions and theories. A simple puzzle, all told. She had the answer before reaching her bed.

She asked the question in a corner of Celestia’s massive room that doubled as a private office, designed for comfort and functionality. It allowed Celestia to do work from an overstuffed chair next to a cozy fire, often while in pajamas as she was now.

Celestia frowned at Luna’s words. Not a frown of concentration or the Official Royal Frown signifying withheld approval, but an honest-to-goodness ‘I actively dislike what you are saying’ frown.

“No.”

Celestia returned her attention to a scroll. Which was good, as she did not see Luna smirk.

“Sister,” Luna half-cooed, half-whined. “You work so hard, even now! It’s dark outside and you’re still at it. No one deserves a vacation more than you.”

It was true. And it was also true that Celestia never, ever took time off beyond her allotted Sundays (and not always those). A thousand years of carrying Equestria on her back had turned Tia into a bona fide workaholic. Celestia counted a silent lunch as a short vacation, and a genuinely free Sunday as a precious gem. Laudable to be sure, but Luna had been around long enough to know Equestria would be fine without its micromanager-in-chief for a week.

Celestia, however, did not take vacations.

Luna slid a pamphlet onto the desk, sprayed with just a bit of her lavender perfume. Celestia did not look. “We’ve been over this, Luna. The affairs of state will not wait.”

“Come on, look!” Luna said. Blue magic lifted the pamphlet up and hovered it before Celestia’s eyes. “You love sunning yourself, you heat fiend. Visit Mare Mesa, lounge and read and see the natural sights. You have screened, paid, and trained ministers to make these decisions, all you’re doing is reviewing what they’ve already done in triplicate. At midnight, might I add.”

“I’m the final word, Luna. I must be an informed one.” Celestia’s tone was bored. Her own magic pushed the pamphlet out of the way and she resumed reading the scroll.

“Twilight and I will handle it. You know she craves to be useful to you, and she is certainly competent.”

The name brought a brief smile to Celestia’s face, which quickly fell. “Twilight should spend time with her friends, not covering for my laziness.”

“I see you’re still wearing that ring I gave you.”

A U-turn in the conversation. Celestia’s eyes instinctively fell to the silver band at her finger. They lingered, and she smiled softly.

“Dear Sister, take a vacation. Just for a week.”

The smile flickered. Again, Celestia seemed to pause like a ticking clock between seconds.

She blinked, blinked again. She said, “But my ponies,” sounding confused and unsure.

Luna slunk around the desk to come by Celestia’s side. Her lavender perfume filled the air. “Dear Sister, they will be fine! Twilight and I will cover for you. You trust me, don’t you?”

“Of course,” Celestia said without thinking. She squinted and blinked, shaking her head a little. Trying to focus.

Luna couldn’t have that. “You look tired, Dear Sister. You should pack in for the night and go to sleep.”

“I...” Celestia paused again, then yawned. “You’re right, yes. I should… go to sleep.”

She stood from the chair, and walked alone towards her bed. Luna followed with her eyes.

“Where would you like to go on vacation, Dear Sister?” Luna asked sweetly.

“The mesa sounds lovely,” Celestia said around another yawn.

“Good,” Luna purred. “I am happy to hear that, Dear Sister. You must pick out the best week next month and let me know so I can coordinate with Twilight. I will make all the arrangements, too. You need only go and enjoy.”

“Mm. Thank you,” Celestia mumbled. She pulled off the fluffy bathrobe to reveal an equally-conservative purple dressing gown. Not even a disappointing peek of her cleavage was visible as she snuggled into the bed, quickly disappearing beneath her comforter.

But Luna was not disappointed. Not at all.

Admittedly, it took another Dear Sister that morning to get Celestia to actually follow through. But she did. The trigger worked, and three weeks later Celestia (who never took a vacation) took a vacation.

Luna made the arrangements, as promised. If Celestia sought relaxation, she could lounge on the sun-warmed rocks and read. If beauty, she could tour the sights and incredible view. If excitement, bungee jumping. All based from a neat little bungalow on the mesa itself, complete with lavender flowers and a grandfather clock. Tick… tock…

Celestia’s subconscious would absorb the obvious. All this fun and relaxation came because she trusted Luna. Obeyed Luna.

Had Celestia come home to a disaster, perhaps her waking mind would have rejected the instinct as a lie. But Luna and Twilight did not simply succeed: they excelled, putting Celestia’s pace of work to shame. It was a mildly embarrassed Luna who then admitted the bulk of credit for this went to Twilight. That girl was good.

The vacation was more than a test. Every obeyed command, every Dear Sister that got results deepened Luna’s influence. The path of Celestia’s subconscious instinct became clear and easy, its flow more natural, its message more acceptable. Trust Luna. Obey Luna when she is in charge.

“Dear Sister, skip that stuffy formal and come stargazing with me.”

“Dear Sister, aren’t you hot in that bathrobe? Summer is coming, you know. Here, I got you this sleeveless night dress, you will be more comfortable in it.”

“A good-night kiss, Dear Sister?”

“Dear Sister, you should sleep in your underwear like I do.”

Celestia did not look up from her work, giving only a humored smile. “No thank you. I prefer decency.”

Luna had influence. Not control.

Yet Celestia wore the sleeveless night dress.

Luna woke up late one evening and got dressed. Not that she was going anywhere, but the quasi-morning routine gave her time to consider and plan.

Celestia’s subconscious had been pushed as far as possible with mundane hypnosis. There were lines her waking mind would not cross, and it held the final call.

Luna brushed her hair in the mirror, evenly meeting her own eyes. She well-knew she would reach this point. The subconscious had limits. This wasn’t a stalemate, simply the beginning of the next stage.

She lit incense, and sat down on a mat in her room laid for work instead of fun. She crossed her legs, adopting a meditative pose. Her eyes closed, her mind opened.

All strictly optional for entering the Dream-Realm, of course. But when your duties involved departing your body for up to twelve hours at a time you learned to leave it in good posture. Luna could see it below her, waiting for her return. Not even an empty vessel. Her subconscious mind – the creator of her own dreams and instincts – silently waited for her return, as did her waking mind.

The Luna of this moment was the dream-Luna. While Celestia’s alicorn power let her shift the cosmos, Luna’s was to wander and control dreams, and to exist in them with perfect awareness.

She floated gently to Celestia, unblocked by magic or stone. Just a dream, after all. The world around her was a translucent mirage, but as she focused upon her sister it changed. She entered Celestia’s dreams merely by willing it, and it was so.

Easy. And she reckoned what came next would be easy, too.

Easy wasn’t always the best first step. The subconscious flowed both ways, and what did she instruct of it? Trust Luna. Obey Luna when she is in charge, which was when she said ‘Dear Sister’…

Or when Celestia was asleep.

Deep blue clouds surrounded them, the color of Luna’s mane although thick and starless. The stuff of dreams, to be lured by unconscious musings or sculpted by Luna’s careful horn. Celestia floated dreamlessly, laid upon her back just the way she slept in the waking world. Dignified even in slumber, with legs down straight and slightly spread, and hands clasped pleasantly on her belly.

Sleeping Beauty.

Here, she was nude. A blessing and a curse. Luna paused to admire the slumbering goddess, hungrily smirking and thinking of great days to come. Full white breasts, Thick and soft to sink her fingers into, topped with fat pink nipples to be sucked and teased. Her kissable lips, her breath like fresh mint with its tender voice. Hips that grew out sensuously, voluptuous but never fat, holding an ass sure to jiggle with every slap and thrust. Legs like marble idols; large, soft feet to be worshiped or tickled as the fancy bid.

Her beautiful body formed a perfect ‘V’ between its legs. How tight would she be, Luna wondered? Would Celestia be clenched and inexperienced, to be worked open like a clam guarding her pearls? Or would her large body accommodate every depravity Luna could dream?

Luna’s smirk faded, letting her thoughts pass from their worship. A blessing and a curse.

She longed for Celestia, craved her sexual touch. This was not Celestia – not the whole of her, anyway. Her dreaming or sleeping mind. Luna could fuck her here ten times over, but with her own body distant she would not truly feel the pleasure. She would just wake up irate and horny, with a cold stickiness down the leg.

To business. And her smile returned. She did not need her body to appreciate what came next.

Her horn glowed, changing the blue clouds to her fancy and whim. A black dungeon with hot coals and iron spikes. Celestia became chained standing to a wall, wearing a tattered and ripped court dress.

That was how dreams worked: you weren’t there, then you were. Celestia’s dreaming mind pulled carefully at her bonds, aware yet clueless, not realizing she was safe in her bed.

A dark, deep chuckle echoed from the stones. Celestia held still, watching with a carefully-disciplined glare as her captor stepped into view. Taller than her by a head, a gray body of waxed muscular masculinity. The fanged mouth grinned, and red eyes swept over her body with animal hunger.

Celestia gave a faint smile. “Hello, Sombra. Back for round four, I see.”

Luna frowned, invisible for she was not part of the dream. She didn’t need Celestia amused and defiant, she needed her weak and… primed.

Like a painter correcting a flaw, Luna made it so. Sombra slammed a hand next to Celestia’s head, now much taller as he leaned in far too close to her face. Celestia trembled and tried to push herself back, her mind altered to become far more afraid.

...And a little horny. She blushed and awkwardly crossed her legs. Sombra was naked except for a red cape and bulging black thong.

Luna smirked at the handiwork. Frankly, dreaming minds had no concept of subtlety. The cheesier, the better.

Sombra gently pulled at the shoulder of Celestia’s dress, sneering at its damage. He did not tear it off – not yet. But the threat was there.

He spoke, darkly seductive. “We need to get you a new dress… for my harem.”

“UNHAND HER, FIEND!”

The opposite wall burst open. Luna strode in, joining the dream with wings flared like a blue angel. She was clad for war in silver chain mail, bearing a sword and shield with Equestria’s icon of the moon in the sun.

Sombra hissed, pushing from Celestia to meet the newcomer. They circled slowly, Sombra gnashing like a beast at the tip of Luna’s sword. All Celestia could do was watch helplessly, because the dream dictated she must.

Sombra sprang – Luna was ready. What once seemed a nightmare turned vastly brighter as Luna dispatched Sombra with a single slice. He screamed, turned to black shadow, and broke apart into nothing.

Powerful blue magic undid the locks on Celestia’s wrists. She fell, but Luna was there to catch her. The chain mail proved soft as bed sheets, and tall, strong Luna lifted her effortlessly like the helpless damsel she was.

Rosy pink tinted Celestia’s cheeks, yet she smirked and raised one eyebrow. “I trust there is a point to this dream, Luna.”

That Celestia could dream lucidly – able to tap just a bit of her waking insight – was something already known and planned for. Luna did not hesitate, adopting a confused tone. “Dream? I thought you were dead, and this is how you greet me?”

“Oh!” Celestia squeaked. “You are… a dream. This is a normal dream. I see.”

Giggling, she gestured languidly to the stairs. “Lead on, brave knight.”

Luna carried her from the castle, and for all her clear amusement Celestia’s blush remained. That’s how the dream went – and Luna was in control.

Luna distracted Celestia with feelings of warmth and sunshine as she examined her next moves. The dreaming mind was more clever than the subconscious, capable of suspicion and thought even when not lucid. But in many ways, it was also weaker. Perception could be altered and tricked easily. Even Celestia’s lucidity was barely an obstacle. Lucid dreaming took focus – Luna distracted her with a kiss on the neck. Celestia stammered, and Luna kissed the lips. Like a pulling tide, Celestia’s mind lost its footing and was swept once more into the delusion of dream.

Luna brought her home, to a great blue castle of art and wonder. Celestia let herself be dressed in dusky velvet, the rescued princess of a strong and lovely hero. They were not sisters, not here. They married that evening, uniting sun and moon into perfect harmony.

When the stars came out, they made love on a massive blue bed. Luna nibbled at Celestia’s neck, fondled her breasts, pinched and poked fantastically with her magic at Celestia’s clit. It was all real to Celestia. She clawed Luna’s back, screamed her name in ecstasy.

They settled down, exhausted, gazing at each other. Luna’s sea-blue eyes… Celestia loved them.

Luna said something. Celestia laughed. This was a dream? Then let her never wake up!

Luna said something else, and it made perfect sense. Celestia was asleep, so Luna was in charge because she was princess of the night.

Celestia knew the rest before Luna told her. Luna was in charge, so Celestia had to obey. That was fine, because Celestia trusted Luna. Her beloved sister.

...That was strange. But Luna told her not to worry, so she didn’t.

Luna mounted Celestia, knees to the bed as she straddled her sister. She leaned down, bringing their faces close. Celestia looked up, up into the beautiful sea-blue eyes.

Luna’s loving smile turned small and cunning. She fixed Celestia with those eyes and commanded her not to look away.

She said much more, but it became hard for Celestia to understand. The dream filled her with so much love for Luna – her hero, her wife. So perfect, so strong. So utterly in command, because this was a dream and Celestia must obey. Here, Luna was her mistress.

It was Luna who said that word, one of the few Celestia grasped. It felt so right. Mistress Luna. Obey Luna.

A clock ticked deeply in the background. Luna’s eyes became spirals of that warm and lovely blue. Celestia floated up into them, so beautiful and comforting.

Luna’s words became clear as Celestia followed those spirals deeper, deeper. “You cannot look away. This is because Luna told you so, and she is in charge. This is alright, because you love and trust her. Luna is your mistress. You obey Luna.”

Celestia’s own eyes turned to spirals. Luna’s horn glowed aggressively, enchanting the defenseless, dreaming mind. The time for deception had passed, at least here and now. Celestia was subsumed in the dream, utterly in Luna’s power. The subconscious instinct that would normally resist such influence was already corrupted.

“Dear Sister...”

Tick...

“Dear Sister...”

Tock...

“You love Luna. Luna is so beautiful, and you lust for her. She is so powerful, so smart, so caring. Luna is your mistress. You obey Luna.”

In truth, only Celestia’s dreaming mind was becoming enthralled. Celestia would awake unaware, and barely effected.

But her subconscious knew that Luna was in charge. The dreaming mind would come to agree, and know yet more. Luna was powerful. Celestia lusted for Luna. Luna was her mistress.

Blue magic like tingling electricity connected their clits. Celestia cried out in arousal, screaming her love and devotion all through the night.

Had Luna left it at that, it would have been an erotic dream and nothing more. Celestia woke that morning as many ponies do, recalling only that she dreamed and then forgetting even that.

Luna stayed up late enough to have breakfast with her. Casually, Luna noted there was a tremor in the Dream-Realm last night. Not an uncommon occurrence, but did Celestia notice anything strange as she slept? The answer was no.

Luna did not use the trigger. Success had brought her to a delicate moment: the dreaming mind was primed for domination, and the subconscious was exactly where she wanted it. Anything with even the slightest risk of alerting her sister was to be avoided like the Cutie Pox.

No, the goal now was much the same as before. Take Celestia’s unconscious in the proper direction, time and time again until the unnatural became… obvious.

Night after night.

Chrysalis had won, capturing Celestia and keeping her in a cocoon of green ichor. She boasted of making Celestia her brainwashed broodmare, but all changed when Luna arrived. She routed Chrysalis, and carried the slime-covered Celestia to a royal bath. She cleaned Celestia in hot water that smelled of lavender. Luna was so strong, so caring… they made love in that bathtub, giggling and splashing as they fumbled blindly in the water to finger each others’ pussies. Celestia gazed deep into her sister’s spiraling eyes and knew she was safe.

Twilight fell to evil magic, unleashing Midnight Sparkle upon the land. She latched Celestia naked and spread-eagle to a table, placing electrodes on her body to sexually stimulate and torment the sun princess until she submits. Lust crazed Celestia, yet she held on. Luna was coming – Luna came, banishing the corruption from Twilight’s body. Celestia begged Luna to bring her to orgasm, and Luna satisfied with her own tongue. Celestia was so grateful that she returned the favor, all while still strapped to the table. They cuddled afterwards, and she listened to the sweet words of her hero. Lust for Luna. Obey Luna.

Daybreaker rose, and this time Celestia was the hero. It came from her own selfish ego, but Celestia knew beyond doubt that she did not stand alone. Luna was by her side. Her equal, her sister, her lover. When night came, it was Celestia’s own humility that banished Daybreaker, for Luna ruled the night and was therefore in command. Rightly, justly, they lead Equestria together. Two as one, proven by the entwinement of their magic, their fingers, their tongues and fluids and bodies. Luna was so beautiful, such a worthy equal and mistress. That made sense, for sometimes she needed to be in charge.

They destroyed Tirek, and kissed passionately atop a mountain.

Tirek defeated them, and threw them into Tartarus. Not even the sisters could take all comers. They worked together perfectly, each with strengths and weaknesses, fending off demons over an exhausting week. Twilight defeated Tirek and saved them, and on their return the sisters fucked all night long.

How could Celestia defend against Nightmare Moon? She couldn’t. The mare tied and ravaged her, pounding her ass with a dildo, dominating her mind into a pliant slave. Luna rescued her, but how to reverse the brainwashing? Luna knew. She hypnotized Celestia to be enslaved by Luna instead, then commanded her to act normally all the rest of her days and never be controlled by anyone besides Luna again. Such a clever solution, from such a wonderful mistress.

They wrestled, laughing. A pillow fight that turned to a tickle fight, that turned to an undignified mashing of lips. It was in Luna’s room, with Luna’s clock.

Again, in Luna’s room. Tea, lavender, clock. Luna’s spiraled eyes dominated Celestia’s. Celestia tried to focus, but her gaze kept drifting down to Luna’s naked breasts. The eyes, the breasts, the eyes. Celestia could see nothing else. A wonderful evening with her beloved sister.

Again. All she did this time was sit and watch the pendulum of the great clock go Back and Forth. Back and Forth. Tick, Tock. Luna prowled behind her, giving mantras to repeat which Celestia did without question. Nothing else across the long hours, and at the night’s end Celestia was permitted to come to the bed and worship Luna’s body for a precious moment.

Again. The same. The clock, the worship.

Again.

And again. Sometimes Luna wore tall black boots for Celestia to kiss. Usually she had Celestia lick her clit to dream-mind orgasm.

Last night, she just had Celestia kneel still and admire her nude blue body, worshiping Luna with helpless, spiraling eyes. Her breath hitched often, and the large pink nipples puckered as though cold. A month of hypnotic dreams had thoroughly conditioned Celestia’s sleeping mind to lust passionately for her sister, her mistress, and to obey her every command. There were no more stories, no more fun scenarios. No more trickery needed to bring the dream mind to heel. Celestia dreamed of Luna’s room, and instantly knew her place.

It was only now, however, that the real victory had come. Celestia knelt once more to Luna, unable to act on her lust for Mistress commanded she only watch.

Yet it was not Luna on the bed. Just a dream. The real Luna paced behind, examining the dream with clinical approval.

She did little, these last few dreams. Night after night of steady enchantment had blessed Celestia with a tiny bit of Luna’s power. Her dream-mind sought what it craved and built this dream itself. Room, clock, worship. Celestia herself was becoming an active ally in Luna’s quest. Her subconscious fed a message of compliance and trust in both directions, and the sleeping mind responded with a wave of lust and submission. If all went well, they would reinforce and support each other, permanently changing Celestia’s mind.

Luna moved as a gardener, carefully pruning the dream. Sometimes the clock’s pendulum held a sea-blue spiral, sometimes there was no lavender. Sometimes Luna was naked, sometimes in lingerie. Tonight Celestia wore an outfit of tight black straps, pinching her crotch and gagging her mouth.

Luna made the gag disappear. At once, Celestia resumed the mantra she was taught to say.

“I obey Luna. I worship Luna. Luna is my mistress. I crave Luna’s touch. I obey Luna. I worship Luna...”

Four lines, over, and over, and over. The distilled and condensed lessons of weeks of unremembered dreams, now a self-sustaining engine.

As a last, careful addition, Luna made sure Celestia could not dream of touching her physically. She could only watch her mistress, distant, desperate for touch that her own dreaming mind could not produce.

The message was clear, if not understood. Celestia needed Luna to cross the threshold, to at last grasp the pleasure she sought. Not just the dream, but Luna herself.

A bit cruel, perhaps. But necessary for the next steps.

Besides, Luna would take good care of her dreams. Celestia’s sleeping mind had cooperated so perfectly that a reward was in order.

Luna wove her own dream, easily dispersing the one that was. A grand castle of black and blue, topped with flags of a lone full moon. This was her dream castle, from which she ruled her nighttime empire. They were not equals here, but Celestia already knew this. Here, Luna was in charge.

Luna permitted Celestia’s vision to hover behind and see herself be led through massive hallways by a chain leash at her neck. Blinders covered her eyes, leather straps closed her mouth. Her only clothes were manacles around the ankles and wrists. Luna marched behind her in a silver crown and blue leather. Every time Celestia stumbled or turned wrong, Luna swung up a black riding crop and slapped her hard across the ass.

It felt so good. Celestia craved the touch. It was in her mantra.

They went down to a dungeon. Stocks latched Celestia’s hands by her head, and magic chains elevated them and her legs from the ground. Ass and pussy perfectly exposed, mouth now forced open by a ring gag.

Luna paused. It felt… strange, seeing her sister so. Quite silly after all Luna had done, but the idea of inflicting torment with her own dream-hands felt a little bit wrong.

“May I go on?” she asked, briefly once more the little sister. She had what she needed. If Celestia’s dreaming mind felt betrayed by the coming pain instead of aroused… Luna would listen.

Celestia was confused, to be asked to choose. But after restrained dreams of only being permitted to look upon godly Luna, the question proved meaningless. She made a garbled noise with her mouth and nodded eagerly.

Luna was merciless. She surprised Celestia cruelly by starting with feathers, tickling the upturned soles, the exposed tits, the helpless anus – or ‘ponut’ as the delightful slang went. Celestia screamed with gagged laughter, then screamed again as the crop returned with more of its kind. Her breasts became pink under the blows, her ass rocking like the sea with each endless swing, never permitted to settle. Blue magic clamped hard on her clit, pulsing jolts of electric pleasure that caused her to arch spine and thrust in vain. A crop found her ponut, and spanked it into a hard red ring.

Then they were all gone, but something came in their place. A strange, gentle tug on her crotch, and Celestia wiggled in disappointment.

Then her blinders vanished, and she saw the milky white dick hanging down from her, right where it would be on a stallion. It twitched half-erect with her arousal, showing a set of generous white balls beneath.

“No you don’t,” Luna teased, seizing the cock with an unnaturally cold hand. Celestia whimpered piteously as her erection fled, shrinking the penis until it fit neatly into the two-inch cage Luna put it in, which she locked with a tiny ‘click.’

The hand grew warm. Luna cooed, cupping Celestia’s balls with one hand while scratching the dick gently through the cage bars with a single nail. She sat down on a nice chair, getting comfortable.

She moved slowly, causing so much more ecstatic agony than the assault before. She pinched and nibbled at the balls, then turned a vibrator to its lowest setting and began massaging where they connected to the crotch. Soft blue feathers ran so slowly along the shaft, drawing babbled laughter with each malicious stroke.

Luna licked the tiny bit of its exposed head, right at the hole. “Come on, Tia. You can do it.”

But she couldn’t. Celestia wobbled in the air, thrusting pathetically. Her dick pressed against its cage, but the pressure only aroused her more in vain, and there was no give.

Minutes. Hours? “Do you want to cum, Dear Sister?”

“Yes!” Celestia screamed. Her gag was gone.

“Then cum.”

Celestia cried out, thrusting against the cage.

Luna stood. “Cum, Dear Sister.”

Obey Luna. But how? Celestia thrust again.

Luna giggled like a child. “Cum, Dear Sister.”

Obey. Celestia thrusted, and did not go back. She grit her teeth, shrieking in the depths of her throat. Her fingers and toes clenched and splayed, hard and fast as they could.

The vibrator pulled away. So did the feathers. “Cum, Dear Sister.”

Nothing. The caged cock was as erect as could be, but no larger.

Luna’s voice grew stern. Celestia was failing to obey. “Cum, Dear Sister.”

Celestia’s cry gave way to a short, sharp scream. A thick ribbon of liquid white shot from her caged dick into the air.

Luna grinned triumphantly and unlocked the cage. Celestia’s penis immediately expanded, brushing aside its prison to launch two more gooey strands across Luna’s chest before it settled, dribbling a last load onto the floor below.

The chains and stock released. Celestia fell to her ass, then clambered to her knees and bowed low. “Thank you, Mistress!”

Now they were on a massive bed, huge and fit for the queen of the night. Luna reclined onto the blanket, now only in black lingerie. She gestured lazily to the white cum still on her body, spattered across her stomach and breasts.

Celestia worked without needing to be told, licking her mistress down while Luna patted her head. When it was done, Luna pulled her panties down. Celestia no longer had a cock, but now a dark blue one rose between Luna’s legs.

“Your turn, Dear Sister.”

Celestia was bound again, locked with leather straps into a kneeling position. With her arms tightly behind her back and legs trapped, only one motion was left to her. She bent and took the whole member into her mouth. Her spiraling eyes gazed intently upon their task as she bobbed her head back upwards, letting her tongue wiggle and wrap, scraping her teeth against the flare, almost pulling her head away as her lips teasingly gripped the very tip before she abruptly sunk all the way back down.

Now it was Luna’s turn to scream. She stammered, arching her back, briefly gone to thought before wondering aloud “Have you done this bef-AH!”

Her eyes rolled back. It was so embarrassing, but between her aroused foreplay and Celestia’s skill she came with the fourth, plunging bob. Celestia drank it down perfectly, and licked what little fell onto Luna’s balls.

Then she was no longer restrained. They cuddled together in the massive bed, both in comfortable, clean lingerie. No pain, sweat, or penis.

Luna worked her magic, hot-cheeked at both her decadent indulgence and its awkward climax. She kissed Celestia’s sleeping face and sent her off to dreams of puppies and laughter.

Then Luna opened her eyes, returning to the waking world. The moon hung high. Her body was right where she left it, folded with practice into upright meditation.

Luna frowned steadily. The comfort of her pose was marred by a dry, cold stickiness between her legs. She reached to the side, grabbed a pillow from her couch, slapped her own face, and fell backwards.

Frustrated, sticky, and unsatisfied. She had lost herself to lust, both for Celestia’s false body and to flex her domination. That last bit with the castle was unnecessary, an utter waste with Celestia’s dream-mind subdued and real, tangible victory within sight.

Still on the floor, Luna reached up and fumbled with the couch cushions. A bit of feeling beneath them found her spare vibrator, and Luna pulled it down to her.

The next steps would be tricky. They would need planning. Such would have to wait until she wasn’t too horny to think.
