Teatime

With a gasp, Celestia shot up in bed, clutching the covers to her chest. The cool night air of the castle caressed her sweat-soaked skin, and her breaths were heavy.

Normally, for her, this would indicate that she'd had a nightmare... but her forehead wasn't the only part of her that was wet.

Her face flushed as she played back the dream she'd just had. The princess didn't often remember her dreams, but this one was particularly vivid.

It had been a long time since she'd thoughts like that. And certainly never about her sister!

But still, the image of Luna's head between her legs, her dexterous tongue tending to her needs...

She flushed harder.

Across the castle, eyes still closed, Luna snickered.

"Good morning, sister," Luna said, stepping out onto the balcony. "Your dreams last night were pleasant, I hope?"

Celestia, froze, teacup halfway to her mouth. A rosy blush lit her cheeks.

"Yes," she replied, quickly regaining her composure. "Why do you ask?"

Luna took her seat. "Mere curiosity, dear sister. You made me promise never to peek into your subconscious when we were fillies, remember?"

This was true. At least she could take solace in that. She allowed herself a smile and finished her sip. Today, she had opted to go with something exotic: a box of leaves that had been gifted to her by Mistmane, the sorceress. She had called it "Bai Jiguan". Celestia called it delicious.

Luna was staring at her. Her own tea set remained untouched.

"Is something wrong, Luna?" Celestia asked, setting her cup down on its saucer.

"Not at all," Luna replied. "Teatime, dear sister."

Celestia's eyes unfocused. Blinked. Focused again. Focused on Luna's face.

"You..."

Celestia blinked again, suspicion creeping into her eyes.

"You did something to me—"

Her eyes widened as the memories came flooding back. She leapt out of her seat, horn flaming like the sun, wings stretching out like a vengeful archangel.

"Who are you," Celestia growled, the question less of a question and more of a demand. "What have you done with Luna. And what have you done to me?"

Luna rolled her eyes. "Sit down and put your horn out, dear sister. We need to talk."

Celestia's legs bent at the command, and she scowled at their betrayal. The flames went out. The wings folded. The look of unfathomable fury, however, remained the same.

"That's better," Luna said, once Celestia had taken her seat. "As for your questions: I am your sister, I haven't done anything with myself, and... well, I think you know what I've done to you." She grinned. "Quite vividly, if your dreams last night were anything to go by."

Celestia shook her head. "You're lying. Luna would never—"

"That's funny," Luna said. "I seem to recall you saying the exact same thing a thousand years ago."

Celestia's breath caught in her throat.

"But the past isn't what's important right now, sister," Luna said. Something teleported into her hands, but she kept it hidden from Celestia. "We're here to talk about your future. Do you remember what I told you, the last time I let you out of your cage?"

She said nothing.

"Being defiant, are we?" Luna said. "Well, savor it while you can."

She stood up, still keeping the thing in her hand concealed, and strode around the circumference of the table, trailing the fingers of her left hand around its edge. "I suppose I can say it again, for your benefit. Don't move, dear sister."

Once again, Celestia felt control over her limbs leave her.

"I'm going to take you..." Luna said, approaching her. She placed her hands on her sister's shoulders.

"I'm going to break you..."

She swung her leg over Celestia's, straddling her, and sat down on her lap. She looked down at her sister with that same, sultry grin, and draped her arms across her shoulders.

"And I'm going to make you mine for the rest of eternity."

Celestia glared up at her. "Is that what you think is going to happen?" She forced out a chuckle. "Then I'm afraid you're going to have your work cut out for you, because I will never let that happen."

"You won't, will you?" Luna said. "Then tell me: what is obedience, Celestia?"

"Obedience is pleasure," Celestia said, automatically. Her eyes widened a moment later as she realized what she'd uttered.

"And who does your body belong to?"

"You," Celestia said, before she could stop herself.

Luna laughed. "It sounds to me as though you've already started to accept your new role, sister. And you were quite eager, the other night... or have you forgotten?"

"Trickery and deceit," Celestia said, a little too hurriedly. "You were controlling me."

"I was doing no such thing," Luna said. "Prevented you from escaping, perhaps, but I never commanded you to beg for my ministrations... or to enjoy them."

Celestia opened her mouth to retort, but before she could utter a single syllable Luna darted in and locked lips with her. Celestia's eyes widened in shock as Luna's hands gripped the back of her head, forcing her into the kiss.

Luna pulled out of it just as quickly. She glanced down.

"I also didn't command your body to do this," she said with a smirk, lightly flicking the visible outline of Celestia's rapidly-perking nipple against her dress. "I did make you unable to notice that you weren't wearing any undergarments, though. Like the good slut that you are."

Celestia flushed. How could she have possibly—

Luna slid off of her, the lengths of her black dress swishing about her ankles, and Celestia finally caught a glimpse of the thing her sister had summoned. It looked like... leather? And something on it had glinted in the breaking sunlight.

Celestia swallowed. She didn't like how warm her cheeks were getting. Luna was facing away from her, and she could see every inch of her shapely behind.

"I refuse to believe that you are Luna," she said.

"Would you prefer it if I were Nightmare Moon?"

"Nightmare Moon was destroyed." Celestia said. "By the Elements of Harmony."

"And yet, here we are. Your sister once again standing over you. And you helpless before me."

"Then that's what this is about," Celestia said, grasping at anything that made sense. It was working; some of the fire had returned to her eyes. "You're attempting to bring about eternal night again."

Luna laughed and turned around. "Oh, Celestia, why would I want to do that? Ponies grew to appreciate my work in your absence, despite your crude mishandling of it. The night is more appreciated now than ever before. Making it eternal would only bring resentment where there is none."

She stepped forward, slid a finger under Celestia's chin.

"No," she said. "I don't want night eternal. I just want you."

Celestia swallowed again.

"But as I said before, we aren't here to talk about the past," Luna said, drawing back. "We're here to talk about your future."

She placed the thing she'd summoned down in the center of the table.

A band of dark-stained leather, smooth and pliable, with a silver buckle securing it at the back. A steel ring hung from a loop opposite, and beside it, burned into the material with the moon at the center cut out completely, was the image of Luna's cutie mark. There was no ambiguity as to the collar's purpose... or who the owner of its recipient would be.

"And this," she said, "is your future."

"You expect me to wear that?" Celestia said.

"You will," Luna promised. "Quite willingly, by the end of today's session. You'll never want to take it off."

"I don't know how you've returned, monster," Celestia spat. "But whatever it is you have planned, I will stop you."

"Oh? But how are you going to do that if you can't even stop yourself?" Luna asked, amused. "Stand up, dear sister."

Celestia stood.

"Strip for me, dear sister."

Off came the dress, discarded to one side. The warm morning breeze brushed against her bare skin, her erect nipples, and the exposed lips of her marehood.

Luna summoned something else from the void, another recent acquisition from her trips into the seedier part of Canterlot. They looked like a pair of evening gloves, but they were black, and made of a shiny, rubbery material. She pulled them on, the cool, smooth latex encasing up to her forearms and molding to every curve.

She gave her fingers an experimental flex. She liked what she saw.

"On your knees, dear sister."

Celestia knelt, her knees pressing into the cold stone of the balcony. She continued to glare up at Luna, struggling not to show how hot each successive command was making her.

Luna circled around behind her. Much like she had during their previous encounter, she planted the tip of her sandal into the space between Celestia's wings and pushed her forward, sending her off balance. This time, however, Celestia was allowed to catch herself, and she did, her hands pressed against the floor.

"Hold that pose, dear sister," Luna said. "And try not to collapse before I'm done with you. I'd hate to have to start again."

With another flick of Luna's horn, the bag from the previous night appeared on the table, as well as something else, which fell to the tabletop with a metallic ring. The bag opened, and the pair of wingbinders emerged, flying over and sliding their elastic selves over Celestia's wing joints.

They were soon joined by the other object: a rod of metal, connected on either side to a par of cuffs. Celestia had never seen anything like it before. Magic spread her legs apart, revealing her dampness. As the manacles clicked shut around her ankles, she felt a twinge in her nethers. Why?

Because to be bound is to be obedient, a voice at the back of her mind whispered. To be bound is bliss.

With both ankles firmly fastened to the bar, Celestia's legs were forced apart. There was no hiding her shame now.

"Eager as always, I see," Luna commented. "You're such a good student."

A moment later, and Celestia let out a grunt as a sudden weight settled on her back. Luna had taken a seat on her, using her as a throne. Luna crossed her legs, and she placed her hands on Celestia's back, one between her wings, the other tantalizingly close to her ass.

"You're almost ready to begin," she said. "But first... how about we make things a little more fair?"

From the bag emerged the inhibitor ring. It floated over, hung in front of Celestia's face.

"I know you know what this is," Luna said. "And I know you know what it does. So how about we see if your will to defy me is really as resilient as you say, hm?"

The ring flew up, out of Celestia's vision, but she felt it as it slid slowly down the length of her long horn. It fell into place, and a moment later, she heard the lock close.

And then another object was dangled in front of her. It was the key, still on its silver chain.

"You may use magic again, dear sister," Luna said. Celestia frowned.

The key dropped to the stone, right in front of her, just inches away from either hand.

"There," Luna said, a tone of smug certainty in her voice. "All you have to do is reach for the key, Celestia, and you'll be able to free yourself. From where I'm sitting, I probably wouldn't even notice until it was too late. You could vanquish me in an instant."

Celestia's heart leapt, and she strained to reach for the key... but her hands remained firmly planted on the ground.

"Of course," Luna continued, "I've ordered you not to move from that position."

She ran her gloved fingers through Celestia's hair.

"But all it would take is one moment," she said. "One moment of self control, and you'll be free. So tell me, Celestia: do you think you can overcome the need to obey that I've so lovingly etched into your brain? Because I'll warn you: by the time I'm finished with you today, you won't have it in you to try any more."

Celestia said nothing. Everything she had was focused on the key. Regain her self control for just a moment? She would do more than that. She'd show the Nightmare that her will could never be broken.

Her arms began to tremble as she tried to will them forward.

Luna laughed. "Defiant until the last, I see. Very well. Then we'll begin."

She turned her attention back to the bag at the table, but paused.

"Oh, and sister... try not to make too much noise," Luna said. "I've made it so that the guards can't hear you, but I've done nothing to stop your precious subjects from seeing what a slut you are."

This was a lie, of course; she wasn't that careless. Not that she'd be telling Celestia that.

She smiled, shifted her weight a little. Celestia's body held firm under her. The stage was set; it was time for today's lesson.

All that was missing was her tool.

Out of the bag it came, floating over to her. Celestia hadn't even noticed.

Luna reached out and took hold of the riding crop. It had a nice heft to it, and it felt good in her latex-coated hand. The degenerate shopkeeper had been right; the gloves did feel amazing.

She ran the end of it across Celestia's cutie mark, traced a circle around her sun. If Celestia noticed, she didn't react.

"I've already taught you the pleasure of obedience," Luna said, continuing to run the crop across her sister's skin. "And you've learned it so well. But today, I'm going to teach you the consequences of disobedience."

With that, Luna levitated the crop around Celestia's backside, trailing it across her thigh and the curves of her ass.

Celestia suppressed a gasp as the end of the crop prodded at her marehood. It pressed against one wall, exposing the caverns inside, and then let it snap back into place. The touch of the cool leather was... intoxicating.

Then it pulled away and—

Thwack!

Celestia grit her teeth as the crop came down on the delicate skin of her ass. She wouldn't scream. She wouldn't give this creature the satisfaction.

Luna pulled the crop away, leaving a bright red welt on Celestia's skin.

"I'm going to teach you what you deserve," Luna said.

The crop returned to Celestia's marehood, the end tracing up and down her puffy folds, threatening to penetrate but never quite getting there.

"And I'm going to teach you to like it."

Thwack!

On the other side, this time. Celestia shouted into her teeth. Another red mark to match the first, and damp with her own fluids to boot.

Celestia forced herself to keep her eyes on the key. If she could keep her focus on it, empty her mind of anything else, then just maybe...

Thwack!

Back on the right side, just inches away from the previous. Tears sprung to Celestia's eyes, but she ignored them.

Luna's gloved hand slid across the raw flesh on Celestia's thighs, her fingers tracing the marks. The cool kiss of the latex soothed each angry welt it touched. Celestia shuddered. It almost felt... good.

"Enjoying yourself yet, sister?" Luna purred, alarming Celestia with how accurately she'd mirrored her own thoughts. "But we've only just started!"

Twisting her hand around, Luna summoned another familiar item from the depths of the bag: an anal plug, emblazoned with the crescent moon. Reaching down, she rubbed the tip of the thing against Celestia's puckered hole, then slowly, so slowly, pressed it inside.

Her hole was more receptive to the plug, this time, loosened from its previous encounter with the silicone toy. It hurt less as it finally popped into place... but the sensation of fullness somehow felt even better.

Then down came the crop again.

Thwap!

Right across her cutie mark. Her body shifted slightly, on instinct alone, and the movement only served the highlight the feeling of the object that had claimed her ass. Celestia bit down on her lower lip. She was beginning to shake, and the heat kept rising...

The end of the crop pressed into Celestia's clit, making her shudder. Half a second later, and Luna's icy fingers descended between her legs.

She bit back a moan. No. She wouldn't break.

The touch started where the crop ended, just below her clit, and trailed upwards, across the length of her slit. Luna's fingers came away wet; the lubrication coating the latex only made the next pass even more pleasurable.

Celestia tasted the faintest trace of iron as her teeth punctured her lip, but she kept her focus on the key. No matter what Luna did, she had to keep focused on—

The crop came down again, harder than before, and in the same moment Luna's fingers pushed their way inside her.

This finally unsealed Celestia's lips; she gasped at the twin sensations. The lasting sting of the crop bled into ecstasy as Luna curled her fingers inside of her. She moaned; she couldn't stop herself.

Luna chuckled. "You make the sweetest noises, sister."

She continued her ministrations, keeping an even, familiar tempo. Every few strokes of pleasure were punctuated by the pain of the crop coming down on her sensitive flesh.

Celestia arched her neck, gritting her teeth together as her breaths grew more and more ragged. Each lash against her skin made her muscles tense, clamping down and rubbing against the invading objects in each of her holes. Her legs tried to clench together, but the bar held them firmly apart.

"I can feel you getting close, sister," Luna said. "But remember: your body belongs to me, Celestia, and so does that delicious cunt of yours. So don't come yet, dear sister. Not until I allow it."

She punctuated the statement with another strike from the crop, again across her cutie mark. The impacts had stained each sun red.

Celestia whimpered. Marecum bubbled out of her with each movement of Luna's fingers, dripping down in long, sticky strands to the growing puddle between her legs.

Luna once again rubbed the end of the crop against Celestia's clit, eliciting another moan and soaking the leather implement in her juices. She trailed it slowly up the inside each of her sister's thighs, leaving wet trails across the sensitive skin. Then—Thwack! Thwack!—she produced red marks across both of them.

"Ah!" Celestia cried, squeezing her eyes shut. Luna smiled. Music to her ears.

She continued working Celestia's marehood, swirling her fingers about for good measure, but she withheld the crop. Instead, she ran her gloved fingers lovingly through her sister's long, multicoloured hair.

Celestia gasped for breath and tried to set her focus on the key again, in this moment of respite. It was still sitting there on the stone, as close as ever. If she could just—

"Well, sister?" Luna said. "How are you feeling?"

Celestia ignored her. She focused all of the will she could muster on her right hand. Luna had commanded her to hold this pose... but there was a way to do that and get to the key. She just had to play Luna's game: go slow.

Her fingers curled and pulled her hand forward, barely even a millimeter, keeping the palm down against the ground. Even though it was almost no progress, it sent a wave of hope crashing through Celestia's mind. She might have started to cry, if the sting of the crop hadn't already coaxed out her tears.

Luna, however, didn't like being ignored.

"I said," she growled, grinding the tips of her fingers into Celestia's insides. "How are you feeling, dear sister?"

"Agh!" Celestia gasped out, her mouth moving on her own. "It, it h-hurts, Luna! It hurts so good!"

Luna's grip relaxed, and her tone returned to its normal purr.

"I see you've finally accepted that I am, in fact, your dear little Lulu."

Celestia bit her tongue.

Luna let out a laugh. "What pushed you over the edge, sister? The realization that no one else would ever be able to make you feel this way?"

The statement was punctuated by another grind from Luna's fingers, making her moan.

"Or did you just finally decide to stop lying to yourself and admit that you were wrong?"

"I didn't—"

"One thousand years I spent on the moon, sister," Luna said. "Alone, in the body of a goddess."

"That... wasn't you," Celestia grunted out. "Nightmare Moon—"

Luna snorted. "We were one and the same, Celestia. Nightmare Moon was me. I was Nightmare Moon."

"N-No..." The heat in her nethers was growing too hot, now, the pleasure building against the wall Luna had erected in her mind. She felt like she'd been placed in a pressure cooker, like she was about to burst...

"Why do you tell yourself such lies, sister?" Luna said, her voice like velvet. "Is it because you couldn't believe your sweet, innocent little sister would dare to disobey you? To hate you?"

The crop trailed across Celestia's thighs.

"Or..." Luna said, "was it just to make yourself feel better about what you did?"

Celestia said nothing, her head hanging, everything she had going to trying to hold herself together, to move her hand forward again before she broke forever—

Luna leaned down, whispered into her ear.

"If that's true, sister, then you really do deserve this."

Thwap! Celestia screamed as the crop struck her clit. Twin waves of pain and pleasure swept through her, crashed against each other with such force she thought she might be broken apart. Her wings strained against their bonds, trying to flare out on instinct.

Luna's free hand began to trace slow circles along Celestia's back, between her wings, and her thoughts began to cloud.

"This pain excites you, doesn't it, sister," Luna said, not so much asking a question as stating a fact. The crop came away, and it came away wet.

Celestia moaned, all self control gone after Luna's last strike, struggling to come back.

It didn't get the chance. Once again, the crop came down on her clit, paired with another thrust from Luna's fingers. Her moan turned to another scream.

"Do you know why?"

Again. A spurt of marecum erupted from Celestia's snatch as she squealed.

"It excites you because it is mine."

Celestia shook, the manacles around her ankles clanking.

"Obedience is pleasure," Luna said, rubbing the crop against Celestia's red, puffy nub. "But you've been disobedient. You've been trying to disobey me this whole time. And so you must be punished."

She pressed the tool down, hard, into Celestia's button, and got another squeal.

"But accepting that punishment," Luna continued, "is just another expression of obedience, isn't it?"

The crop let up for just a moment before it struck her again. This time, she didn't scream. She moaned.

"And to be punished by me is just another form of my taking ownership of you," Luna said. "And to be owned by me is bliss, isn't it, sister?"

"Y-yes!" Celestia shouted, and was rewarded with another strike from the crop. "Ah!"

"And you deserve it, don't you?"

Silence.

Thwack!

"Don't you?"

"Yes!" Celestia cried out. "I deserve it!"

"You want to be punished for your disobedience, don't you, sister?" Luna said. "If it brings you this much pleasure?"

"Yes!"

"You enjoy being punished for your disobedience."

"Yes!"

"You enjoy being praised for your obedience."

"Yes!"

"You want more."

"Yes! Please, sister!"

Thwack!

"Agh! Ha... ha..." Celestia's lips had turned upwards, into a smile.

"You deserve this."

Thwack!

"You deserve every minute of this, Celestia."

Thwack!

Thwack!

Thwack!

"And you love it."

Celestia moaned, and panted. Drool dripped from her mouth. Cum dripped from her reddened snatch. Sweat dripped from her brow. The key glinted on the stone, ignored.

Luna pressed the crop into her clit again. "Do you want to come, sister?"

"Ah, yes, please Luna, ah..."

"Are you going to obey me from now on?"

"Yes!"

"Willingly?" She ground the crop in harder.

"Agh! Yes!"

"Then I suppose you deserve your reward, for being such a good slut," Luna said, smiling. "Come for me, sister. Come as hard as you can."

"Ah... ha... AHHH!"

Celestia erupted. Luna pulled her fingers out just in time, as wave after wave of Celestia's juices flooded out of her puffy folds. Her entire body shook, trembled with each spurt of her orgasm. She tried to keep upright, but her body wouldn't obey and her arms gave out, sending her pitching forward, breasts and cheek grinding into the stone under her sister's weight. She twitched, moaned, twitched again as her arousal puddled behind her.

Luna slid off of her sister's back, watched as she came, and came again. The thing on the floor wasn't Celestia; it was an animal, reduced to pure instinct as her mind deserted her. She smiled, and lifted the dripping fingers of her left hand to her mouth. Her tongue slithered across the smooth latex, savoring every drop of her sister that remained on them.

Eventually, Celestia stopped twitching, and the stream from her marehood turned into a slow drip. Her moans turned to shuddering gasps as her lungs heaved for air.

Once Celestia had just begun to catch her breath, Luna squatted down next to her.

"I told you not to collapse, sister." Her smile was cruel as she bent the crop in her hands. "You know the punishment for disobedience..."

Celestia said nothing, too far gone to reply.

Luna flipped her over onto her back. Celestia's arms splayed to either side while Luna sat atop her, straddling her stomach. Celestia could feel the dampness seeping through her sister's underwear as it pressed into her skin.

The crop slid under Celestia's chin, forcing her head back, then trailed down, tracing over her collar, along her breasts.

Then, grinning, Luna brought the crop down laterally, cracking it across both of Celestia's thick, aroused nipples.

"Gah-AH!" Celestia screamed. Her hips bucked.

The crop returned to Luna's magic. The cold latex made her shiver as Luna grasped her breasts and began to play with them, kneading and squeezing in all the right places.

She felt the end of the crop brush against her folds, her legs forced to accept it by the spreader bar. It forced its way inside, making her tense up as the foreign object began to roughly fuck her. It penetrated deep, deeper than Luna's fingers ever had.

And Luna didn't let up, either, continuing to massage her supple breasts. She took Celestia's nipple between her thumb and forefinger, pinched it, twisted it. Pain or pleasure? She couldn't tell the difference anymore. It was such a sweet, sweet agony...

She moaned, and Luna knew she'd won.

She bent down, practically laying on top of her sister, and kissed her again. This time, she forced her tongue inside, and met no resistance—even, she thought, a hint of eagerness.

"I think you're ready," she said, drawing back, a trail of saliva connecting their lips for just a moment. With a wave of her hand, the collar on the table levitated over. It hung in the air over Celestia's head; her eyes lazily focused on it.

"What is obedience?"

"Pleasure," Celestia gasped out. The crop continued to thrust into her.

"And the punishment for disobedience?"

"P-pleasure and pain!"

"And just who does your body belong to, sister?"

"Y-you!"

"Good girl." The collar lowered. "Put it on, sister. Display your obedience to me. Display proudly the mark of your owner."

The thought of obeying gave her pleasure. The thought of not obeying hurt, and that hurt also gave her pleasure, and that pleasure made her yearn to obey.

Celestia's trembling hands reached for the collar.

The dark leather slid across her skin. She pulled it tight, restricting her throat just enough that she would feel it with every breath. She moaned with happiness as her fingers threaded it through the buckle, locking it in place. Celestia's pale skin showed through the moon-shaped hole, completing the design. It was now the spitting image of the mark that adorned Luna's flanks.

Celestia's arms fell back to the floor.

"I'm so proud of you, sister. You make such a wonderful slave."

And Celestia came again. Not as hard, this time, but enough to make her quake with euphoria.

The crop slid out of Celestia's snatch, making her groan. Luna held it in front of Celestia's mouth, her fluids dripping off of it and spattering on her face.

"Clean up after yourself, sister."

Celestia's tongue extended out, and she licked it clean. Luna gave her breasts another squeeze, and Celestia moaned again, low and needy. Luna would have killed for another hour with her, but much longer and ponies might start to worry where their princess was.

"Well, I've enjoyed playing with you, Celestia," Luna said, reaching up and brushing a few stray strands of her sister's mane out of her face. "But it's time for you to go to sleep again. Fall into a trance for me, dear sister."

Celestia's posture immediately relaxed, and her eyes fell half-closed. She laid there, not moving, awaiting Luna's new commands.

Luna tapped the buckle of Celestia's collar with a finger. The collar shifted, its form melting into something new.

When the magic had done its work, it was no longer a leather collar that surrounded Celestia's throat, but a symbolic one—a necklace, a thin chain with a silver moon hanging from its middle. It slid down, the cold metal resting against the skin of her chest.

"When I say 'teatime is over, dear sister', in addition to forgetting what has transpired here today, you will remember me giving you that necklace as a gift. Say, 'yes, sister'."

"Yes, sister."

"You love your new present. You never want to take it off. You will never take it off. Say, 'yes, sister'."

"Yes, sister. I will never take it off."

"And when you look at it, you will think of me. Say, 'yes, sister'."

"Yes, sister."

"You will not be able to notice any sign of our time together. You will not be able to feel the marecum dripping down your legs, or the smell of your own arousal. You will not notice the marks or the bruises on your body. If they ache, you will interpret them as your muscles cramping from stress. This will in turn remind you of me, and how refreshed you feel after our meetings. Say, 'yes, sister'."

"Yes, sister."

"You will not allow anyone besides me to see your body until they have healed. Say, 'yes, sister'."

"Yes, sister."

"And finally," Luna said, "Twilight Sparkle. Tomorrow, she is going to offer to come to Canterlot and help you with the preparations for the Summit. You are going to accept her offer. Do you understand? Say, 'yes, sister'."

"Yes, sister."

Luna smiled. "Good girl."

She stood up, looked down at her conquest. Celestia was a mess, covered in sweat, drool, and her own sexual fluids. The bright red marks from Luna's crop stood out against her skin.

The manacles around her ankles clicked open, the bar clattering to the stone. The bands around her wings slid off. And the key, almost completely forgotten, floated up and unlocked the inhibitor ring, which slid off and joined the other toys on the table.

The anal plug, however, remained where it was.

"Up you get, sister," Luna said, offering her a hand and pulling her up to her shaking feet. "And get dressed. You have a long day ahead of you."
