Tea and toast. A light breakfast, at nine in the evening. Celestia had gotten her in the tea habit, and Luna had to admit it woke and refreshed her better than coffee. She sipped, eyes down and away.

It had been a week since her little indulgence in the castle. Luna’s duties were small, but they had piled up over the course of her project. Night Court and a few wandering nightmares had to be addressed, as well as a more personal touch when a fashion designer’s attraction to her colleague turned into guilty dreams.

Why be guilty of love? Luna gave a light snort, though she knew the feeling better than most. She only hoped she was able to steer young Coco in the right direction.

“And now,” Luna sighed theatrically, “to steer myself.”

It was almost burdensome, how well things had gone. If there was a time to meet complications it was in the dreams where she had control of the field, or with the gentle hypnosis of before where her intent could be disguised. These coming plays for domination of Celestia’s waking mind… this was the point of no retreat. There would be no recourse if Celestia woke up to herself eating Luna’s pussy. Nothing to come then but a quick trip to the moon; or more likely, the sun. Celestia would feel her trust betrayed, mistaking Luna’s love for a coup or some other nonsense.

Luna pictured her, shocked and sad and enraged, then pushed the image away. It would not come to that. It must not, and it was on Luna to make it so.

The groundwork was laid well. Celestia’s dreaming mind was in her thrall, worshiping Luna as lover and mistress, always hidden beneath other dreams before Celestia woke. It fed and informed the subconscious – less pliable, but paved with its own message of submission. A self-feeding echo, growing louder in the depths of Celestia’s mind until her waking self found it logical and right. At least, if all went well.

A chessboard sat on a nearby desk. Black had forced white into a corner, but white’s strongest pieces were unclaimed. Any wrong move could turn advantage to disaster.

Black needed to be patient, but had to engage. The time for delicately avoiding all risk had passed.

A knock.

A lazy smile. “Do come in.”

Celestia entered, still in her white court dress. Work had run long today, and may have gone longer if not for Luna’s invitation. “Dear Sister, come sample this new tea with me.”

At least the woman had taken off her pumps and crown first. Still, Luna snickered. “This is not a formal occasion, Tia.”

Luna herself wore nothing but black lace unmentionables. Celestia smiled back, well-used to her sister’s immodest privacy.

Less commonly, her eyes drifted to the blue, toned belly and below before coming up very quickly.

The white princess collapsed to her chair with a sigh. “I’m so sorry I’m late, it was just...”

“Hush and shush, Dear Sister.” Luna cooed, walking around behind her. “Leave all that out there. Here, it is just us two.”

“You’re right,” Celestia said, still a bit breathless. “It’s just such a puzzle to adapt to Thorax’s kingdom. The changelings still have bad apples, how do we protect against them without–”

Luna hugged her from behind. Celestia tensed as the bare blue arms enfolded her bosom. Sudden warmth crept into her body. Instincts – the subconscious – had taken lessons from the aroused dreams.

“Be calm, Dear Sister.” Luna felt the tension fade at her command. “Here, there is just me. You are safe and warm.”

Here was the clock, the lavender. Celestia’s eyes fluttered, her subconscious rolling easily down the path prepared for it. Safe and warm. With Luna, who she trusted.

Her waking mind stumbled, finding it odd that trust specifically came to mind. But that was Celestia’s own fault; it’s not like Luna said anything strange.

Celestia’s eyes drifted to the blue moon on her finger. Yes, she loved and trusted Luna.

Luna kept the embrace, rocking her sister gently from side to side. Her magic poured the tea. “There we go. Forget about it all til tomorrow, Dear Sister. You are safe, warm, and happy.”

Celestia nodded slowly.

Tick...

“Can you say it for me, Dear Sister?”

Tock...

Celestia was a bit confused at that. But she was very tired, and trusted Luna.

“I am safe, warm, and happy.”

It was like the words had power. Celestia felt cozy contentment blossom inside her like strong wine. Why had she been in such a tizzy before? She didn’t even remember.

She smiled, broad and drowsy, listening as Luna spoke. What a wonderful sister, helping her unwind from the stress.

“It feels so good to be embraced by me.”

Tick...

“Touched by me. I make you feel good, Dear Sister. My touch makes you feel good.”

She shifted the hug, both palms down around Celestia’s breasts. Innocent, surely. Celestia trusted Luna; it wasn’t her fault Celestia’s body blushed at the touch.

It felt good, just like Luna said.

Luna watched carefully as Celestia drank down the tea. No dream magic, this time. The waking mind could be ignored no longer. She whispered more words of gentle comfort, timing her pauses with the clock.

As it had months before, Celestia’s breath slowed, and her eyes became dull and unfocused. A trance, this time brought not by magic or hypnotic droning, but an alliance of subliminal messages. Clock, lavender, Dear Sister. Luna wiggled her fingers, catching Celestia’s gaze with the orange sun on her ring.

There was something else, too. Something on the tip of Celestia’s tongue that she was to say, as certain and repetitive as the clock. But she could not remember, and was too contented to try.

Luna removed her arms. Celestia shivered a little, frowning sleepily without her.

“You’re very tired, Dear Sister.”

Luna watched Celestia’s head droop lower with the words.

“So very, very tired. Too tired to think. It is so much work to keep your eyes open.”

Tock…

“You’re too tired to make it back to your room. Aren’t you, Dear Sister?”

It was true. Luna said so. Celestia said, “Yes.”

Luna gave her a kind smile. “Well, you can’t sit there all night. Sleep with me in my bed, Dear Sister. That is alright. We have shared beds before, like on my first night back.”

The nostalgia sent a wide smile across Celestia’s face. But Luna paused, pretending to remember something. “Well, you won’t be comfortable sleeping in that dress. Take it off, Dear Sister, and sleep in your underwear. That is alright, because it is just me here and you trust me.”

She tensed as she said it. Celestia, however, did not. Swayed by the logic, she stood and began stripping before Luna’s eyes. Enchanted white silk fell carelessly to the floor, and Celestia stepped from the pile wearing only blue, functional brassiere and panties.

Luna sat on the bed, proudly exposed in her own lingerie. “Come, Dear Sister.”

Celestia walked slowly, too tired to think. She crawled into bed, and Luna held her close. It felt good.

Luna hugged Celestia’s face into her modest breasts. Now unseen, she allowed her smile to become wicked.

“You are in a trance, Dear Sister. That means your mind is both asleep and awake. Do you understand?”

“Yes,” Celestia said.

“What do you say when you are asleep?”

Celestia blinked with heavy lids. What… did she say? It was that thing she forgot. That thing she was supposed to say, right at the edge of her lips.

“Say your mantra, Dear Sister.”

Celestia was too sleepy to wonder or object. Too drowsy to notice her lips begin to silently repeat the words. But that was fine – her instincts knew this was the normal, natural thing to say when asleep. And she felt so good in Luna’s arms.

It emerged a soft, sleeping mumble. “I obey Luna. I worship Luna. Luna is my mistress. I crave Luna’s touch...”

She got through three repetitions before falling asleep. Safe, warm, and happy in Luna’s arms.

Luna didn’t have as hard a time as she feared in restraining herself that night. This was the endgame, and she would not ruin it. Like that chessboard, one measured move after the next, slowly bringing her sister to checkmate. Like that ticking clock: Tick…

“Dear Sister, let me handle the Buffalo summit this time. Go to the spa. You deserve it.”

Tock…

“Dear Sister, try sleeping naked tonight. I’m told it’s wonderful for your rest.”

Luna’s dream-self held her breath as she approached Celestia’s room that night. She arrived to find Celestia’s fat pink nipples exposed to the air as she laid back in slumber, and the white ‘V’ of her crotch nude and exposed.

Luna threw back her head and laughed.

There was no longer even any temptation for hollow dream sex. Not with Celestia’s resistance crumbling away. Not with her inhibitions fading, her instincts molding to Luna’s will. The unthinkable had turned into second nature.

“Take tea with me this evening.”

Luna spoke knowing full-well it was the first day of the Canterlot toy fair, an event Celestia childishly adored. She would decline, or at least protest.

Instead, with a slow blink and second’s pause, Celestia blandly answered, “Yes.”

And she came. “Dear Sister” was obsolete. With so much repetition of so many subliminals, her waking mind found it right and natural to obey. Luna was in charge. The need to only be so “when asleep” had disappeared as the nighttime mantras of utter submission lodged deeper and deeper into Celestia’s subconscious.

This was the beginning of Luna’s victory. All Equestria was hers for the taking.

Of course, she did not want that.

Instead, she apologized for ‘forgetting’ and went out with Celestia to a lovely evening at the fair. They bought giant stuffed animals for each other, giggling, arm in arm. They got one ice cream bowl to share and ate it, cuddled close on a bench in the warm night air.

It was quite late at night when they stumbled back to the castle. Celestia turned towards her room, but Luna caught her arm.

“We’re going this way, Tia.”

Celestia did not question. It was not worth questioning – she trusted Luna. Blue hand held white as Luna lead the way down a different hall, both sweating faintly at the touch.

Celestia felt her heart skip beats. Luna’s simple perfume of elderberries seemed somehow heavy, and a low burn came to Celestia’s chest. To spin Luna around and kiss her with wild abandon, to throw off these silly clothes and worship Luna’s body with mouth, with hands, with holes…

Words without context found her mind. ‘I crave Luna’s touch.’

Celestia’s own, conscious thoughts. Luna’s touch on her hand made her happy. Luna, her strong sister, leading the way. Her shapely, beautiful sister…

…‘Sister.’ Celestia withdrew her hand, tried to banish the arousal from her mind. Her feelings were wrong.

Luna pouted, but Celestia kept following. All the way to a familiar room. Luna opened the door, releasing the scent of lavender and dull tick of the clock.

They walked inside. Luna closed the door, surveying her sister as she did. Celestia had come obediently enough, but something was wrong. The elder sister looked away, brow furrowed in worry.

“What ails you?” Luna asked with gentle kindness.

Celestia’s mouth moved to say, “nothing,” but it did not come. Luna asked for an answer, and that was not it.

Still, her mind dodged. Celestia stumbled, speaking in fits and starts as the subliminals prodded her to comply. “It is… shameful. It, it was a beautiful evening, Luna. Very… romantic.”

She closed her eyes, blushing, grimacing hard. “I’m sorry, I...”

She got no further. Luna hugged her, kissed her upon the lips. Her smaller breasts pushed into Celestia’s, and Celestia at once felt her shame vanish to nothing. Luna’s touch… the taste of her tongue, entering Celestia’s mouth…

They parted, panting, after many long seconds.

Luna spoke, like honey and opium. “Everything is fine, Dear Sister. And soon it shall be even better.”

“Now… look into my eyes.”

Celestia looked. Luna’s eyes had become sea-blue spirals.

Luna’s hand snaked up, gripping Celestia beneath the jaw. Fingers and thumb squeezed her cheeks, keeping her head steady and fixed towards Luna.

Luna grinned, though at least a little of it was fear. This was undisguised magical mind-control. The moment of truth: Luna would either conquer Celestia, or become a smear on the rug.

Celestia feebly wiggled in Luna’s grip. She seemed confused, blinking and squinting as though the light was too bright. “Luna, what...”

“Hush now,” Luna said with sweetened calm. “Quiet now. Trust me, and look deep into my eyes.”

Celestia did trust Luna, with every fiber of her being. And it felt so good, to have Luna touch her. And Luna was in charge.

So Celestia relaxed, and stared. Soon, blue spirals replaced her eyes as the spell took fully hold. The subconscious that would normally scream its warning instead whispered that this was right and good. The dream-mind that would normally wander free found these mental chains familiar and comforting.

And now, the waking mind was Luna’s to command. She had won.

“What is your mantra?” Luna asked with low authority.

Celestia hesitated only one second before at last knowing the message of her dreams. “I obey Luna. I worship Luna. Luna is my mistress. I crave Luna’s touch.”

“Good,” Luna breathed. “Now… strip for me, slave.”

‘Slave’ was a bit unnecessary, but Luna damn well deserved this. She watched, biting her lip, fondling her crotch as Celestia stripped herself down. No restraint needed, not anymore.

Celestia had worn pink underwear today. Her slow, mesmerized movements unclasped the brassiere, causing her full breasts to fall, jiggling slightly as they came to rest. She pulled down her panties, revealing her shaven pink pussy to the air.

“Come here,” Luna said. One more step. With the moment of victory at hand, she found she did not mind dragging it out.

Celestia moved, and knelt down at Luna’s command. Luna took her time in removing her own clothes, drinking in the still submission that came so naturally to Celestia’s mind.

Luna sat on the bed, teasingly opening her legs on level with Celestia’s head. Her own private lips were darker than the rest of her body, and capped with a cute blueberry clit.

Just like the dreams. But real. To one such as Luna, it was the difference between making passionate love and reading about it.

Her magic pulled open the nightstand drawer. Out floated the final move: a small, sea-blue gem on a silver thread.

She dismissed the magic in Celestia’s eyes, but there was no time to recover. Celestia’s pink orbs blinked, then fixed upon the gem as Luna began waving it back and forth… back and forth…

Enchantments could fade, after all. Luna didn’t need Celestia to be mesmerized, she needed her mind permanently changed. This pendant was the second half of a long, slow-building spell. The first half, a blue-moon ring on Celestia’s finger.

“Gaze into the pretty gem,” Luna said. The ring had done its work, magically pushing her subconscious influence ever upwards. This was the finishing touch, binding it all together.

“Gaze deeply into the pretty gem. Let your eyes follow as it swings, as it sways. Let it pull you in. Let it unveil the truth to your waking mind.”

Celestia followed the gem perfectly. Luna swallowed. “I am your mistress, and you are my slave. You obey me, you worship me. You trust me, you love me, you lust for me. None of this betrays what you are, for you still love our little ponies, and all Equestria. We were meant to be together, as lovers.”

“Now: repeat your mantra.”

Celestia immediately spoke in a dull monotone. “I obey Luna. I worship Luna. Luna is my mistress. I crave Luna’s touch.”

The spell made her waking mind utterly open to her dreams and subconscious. What resistance she had left was drowned in a wave of mantra and obedience. At last, Celestia’s psyche was in perfect union.

Celestia kept repeating lowly as Luna went on. “You must accept these truths, Dear Sister, because you are helpless to me. Your every instinct and dream binds you to this reality. Your waking mind accepts it as natural and good. This is ‘you,’ Dear Sister. This is the ‘good’ way to be, the ‘right’ way to be. This is who you are.”

Luna watched, letting arousal’s pleasant burn build within her. Over and over, Celestia said those four lines, never taking her eyes from the gem. “I obey Luna. I worship Luna. Luna is my mistress. I crave Luna’s touch.”

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

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

“You may finger yourself,” Luna purred.

Celestia obeyed, hooking two long white fingers into her pussy. She pumped them slowly, in time with the gem’s sway. Her eyes never left, and her mantra never slowed.

The minutes ticked by with delicious sloth, and Luna felt the gem’s magic gradually fade to nothing. The spell was done, linking the hypnotized certainty of Celestia’s conscious and unconscious.

Luna set it down. Celestia kept chanting, kept masturbating.

Luna spread her legs wide. “Now,” she said, “Gaze upon my body, and know that it is yours to adore, to worship, to fuck. Just as yours is for me. I am your mistress, but you are my equal, my co-ruler, my lover. I love you, Celestia. I want to indulge your secret kinks, and to give you pleasure as great as what you give to me. Stop chanting, and stand.”

Celestia did so. Luna smiled impishly, closing her legs. “But I will go first. Come, sit on my lap.”

Celestia was taller and wider than Luna, though Luna’s strength let her accept it with comfort. She hugged Celestia from behind and nuzzled the white neck, getting a giggle from Celestia. Vanilla and sweat, undisguised by clothes. Luna breathed it in, kissing and nibbling at the neck, working her way up to the cheek, then the ear.

Her hands moved as well, first exploring Celestia’s belly. Long blue fingers stroked gently, drawing more giggles as they drew up along her sides. They pressed, finding firm muscle. Celestia had tough abs beneath her delightful squish.

The touch was a drug to Celestia, feeding an addiction she never knew she had. The hands moved steadily upwards, pushing up beneath her breasts and fondling them, letting them overflow between fingers and over nails. Luna moved slowly, groping, massaging out gasps and squeaks until her forefinger and thumb found each puckered pink nibble.

Luna breathed unsteadily, grinned evilly. She pinched hard, pulling out on Celestia’s nipples.

Celestia gasped, arching her back and stammering.

“Something to say?” Luna sneered.

“Th-thank you, Mistress!” her sister replied. It was in Celestia’s mantra, her truth. She craved Luna’s touch. She needed it, wanted it.

Celestia’s hands moved low.

“Aw, is my sister needy?” Luna chuckled, now pushing back on the breasts with a groping squeeze, kneading into the soft texture. She lowered her voice. “Do you want to cum?”

Celestia gasped and nodded. Luna pulled back her right hand and slapped the breast. “Don’t be so impatient, Dear Sister. This is our first night together as lovers. We can take our time.”

Celestia set her hands to the bed and grasped desperately at the sheets. A noise like “Nnnnng!” came out through her throat, interrupted by a sharp gasp as Luna’s left hand slipped from the breast to gently touch between her legs.

“Of course, in some ways this isn’t our first night together.” Luna spoke teasingly, letting her nails brush and run along Celestia’s hidden folds. “Do you now remember your dreams of me? So many erotic dreams of us making love, of you worshiping me, enslaved by me?”

“Yes,” Celestia gasped. Her psyche was whole. She remembered them all.

“I gave you those,” Luna said, chuckling with dark liberation. “I made you into this. My enslaved, submissive fucktoy, did you think these new feelings came naturally? Prudish Princess Celestia would barely consent to a chaste kiss, and now look at you. Desperate, horny, a bitch in heat.”

Their feet played on the floor, interlocking toes and rubbing against each other. Luna’s horn glowed, creating a tight magic clamp right on Celestia’s tender ponut. Celestia squeaked and wiggled, distracted by pain and arousal yet not willing or able to climb off.

Luna’s hungry voice went on. “Welcome to the rest of your life. My slut, my slave, we’re just getting started. You will be whipped and chained, blindfolded and gagged. You’ll be tickled to insanity, you’ll be edged beyond belief. You’ll suck dildos – ha! And you’ll wear them for my own pleasure. You will worship my body, just as I worship yours.”

The strong, voluptuous white body, completely real beneath her touch. Everything Luna craved was in grasp, now and forever. Not a dream, but real.

“Unless, of course… you can break out?” She leered. “Try to break out, Dear Sister. Try to not be my submissive slave. It’s your last chance, after all. You can do it. If you fail here, you’ll be my obedient slut forever.”

Nothing but a tease. Celestia tried to break free, but only because Luna commanded it. She must obey Luna.

And why would she want to be free? Even the pain and denial Luna gave was raw pleasure beyond any she had ever known. And she loved Luna, and trusted her.

She grunted and shuffled, petering out after only a few seconds.

Luna released the breast to run her hand along Celestia’s cheek. “Aww… such a good effort! Did you escape my control?”

“No, Mistress,” Celestia said. Her breath hitched as Luna’s teasing nails found her clit.

“Then it’s settled. You are my obedient, submissive slave...”

Luna breathed the last word, letting it tickle over Celestia’s ear. “Forever.”

“Yes, Mistr-GUH!”

Luna’s fingers dug sharp and fast into Celestia’s pussy. Her thumb began flicking along the clit, her magic at the ponut changing from pain to penetration.

“Now,” Luna said jaggedly. “At the count of three, you will cum. Do you understand?”

Celestia nodded desperately. “Yes, Mistress!”

“One.”

The blue fingers scrambled inside Celestia. The thumb pushed hard on her clit.

“Two...”

The fingers swept up, squeezing the clit from the inside while the thumb rubbed from without. Luna’s free hand gripped a white breast. The pillowy ass bucked against her, and she bucked up in return.

“Three!”

Celestia screamed without breath, releasing only a strangled moan. Only Luna’s grip stopped her from launching from the bed as a burst of thick, clear cum squirted out before settling to a leaking flood.

Luna pulled out her fingers, licked greedily at Celestia’s – Celestia’s! – juices.

...Admittedly, it did not taste as good as she expected. Perhaps a spell or enchanted jewelry would help, next time.

Now, though, another matter. For all her teasing and toying and playing with the magnificent body that was now hers, Luna was desperately horny. Her cruel kink fell to urgency as she stood, half-shoving Celestia from her.

“On the bed. Now.”

Celestia complied. Luna tackled her instantly, without one drop of patient, teasing finesse. She kissed the breasts, suckled at their nipples, buried her face between them and simply breathed, eyes rolling to the ceiling and beyond. She ground her clit against Celestia’s leg, humping it without a shred of dignity, pushing herself as tightly into the woman as she could.

She raised her head for air. Their eyes met. Celestia’s half-lidded pink gazed upon her as an adoring wife.

They blurred.

“I love you,” Luna gasped.

She blinked, the vision cleared. Celestia smirked, with one eyebrow raised.

She rolled, taking Luna with her. They fell to the other side of the bed, now with Celestia on top. The heavy breasts dangled down, resting atop Luna’s.

Their eyes met again, Luna breathlessly startled, Celestia with a puckish wink. Then Celestia began to worship – slower, more patient than Luna’s desperate affection. Her mouth found Luna’s left nipple – kissing it, nibbling it, and nothing else for a minute or more. Arousal burned insanely within Luna but she gripped the sheets, reveling in the madness.

Celestia worked her way down slowly, breath catching with her own lust. She loved Luna’s body, worshiped it beyond any faith. Every kiss was as much pleasure for her as for Luna. But she was steady, patient. Tiny, gentle kisses worked their way down the toned blue belly, lingering teasingly just below the navel. Then lower… lower…

She settled before Luna’s clit, pausing to admire it. A tiny, cute little blueberry. Celestia licked it like a kitten, then giggled as Luna’s whole body rocked. She kissed it, so lightly that she could kiss a ladybug with the same force and leave it unharmed.

Then, with the same perfect delicacy, Celestia pushed her head lower and took the clit in her teeth, gently nibbling.

It only took a few seconds for Luna to scream, cumming the whole evening of arousal out into Celestia’s mouth. Celestia swallowed and drank more, adoring even the warm fluids from Luna’s pussy.

Luna kept coming, Celestia kept swallowing. Not an evening, but years of building passion, released at last. Luna fell back to the bed at the end of it, utterly spent.

“Come here,” she mewled.

Celestia obeyed. Luna hugged her close, sniffling, babbling. “You… you need to be happy, too. I don’t want to take over Equestria or anything, or, or actually make you a slave. You still have hobbies and a life, just with me as your lover! We should come up with a safe word so I don’t actually hurt you. We...”

She gulped hard. “I want to have a romance with you, without having to hide it. I want to start leaking word that we’re not really sisters, it was just a formal title. Give a few years to become common knowledge, then I think we could safely court.”

“Leave that for tomorrow,” Celestia said, as tender as ever. She hugged Luna and Luna hugged back, pushing her head into the white bosom. “Rest, Mistress. Catch your breath. We’ve had quite a night.”

“Not yet, we haven’t.”

Luna peered up from Celestia’s breasts. Her eyes were dry, and her hands wandered down until they reached Celestia’s ass. They squeezed, earning a gasp.

“The night has just begun, Dear Sister.”
