Teatime

Celestia took a sip from her cup and sighed. "This is lovely, Luna. I should have asked to try your blend years ago."

"I'm glad you enjoy it, sister," Luna replied, smiling. "It took me a long time to get it right."

Two days had passed since Luna had first taken Celestia's mind, and in that time Luna had carefully watched her sister for any signs of her control breaking.

It had been simple things; she'd started by asking her to do things she'd never object to normally. Fetching her trivial objects from around the castle, or answering simple questions. When there had been no deviation, she'd begun to escalate. Asking her to sit out on important meetings. Asking to attend them in her stead. Asking her to sway this or that way in matters of state, even if she'd been leaning the other way previously.

There had been no resistance so far. Now, it was time to see how far she could push it. She needed total control over her sister's body before she could continue Celestia's training, and Luna was itching to begin the next lesson.

But—all things in good time.

"How go the preparations for the Solstice Summit?" Luna inquired, taking a sip from her own cup. She'd given Celestia the same lavender blend as before, but for herself, just now beginning her night, she'd prepared a second-flush darjeeling. A personal favorite of hers.

She'd waited for evening tea, this time; the sky framed behind her sister had taken on an ever-darkening orange hue. She'd have all night with her sister.

She intended to use all of it.

"Oh, just as frustrating as always," Celestia said, frowning. "I swear, arranging meetings with foreign dignitaries is worse than herding cats."

"Some of the dignitaries are cats," Luna pointed out. "Partially, in the case of the griffons."

"Don't remind me." She sighed. "I'm glad Griffonstone is finally starting to get its act together, but Godfried... well, I hate to speak ill of a fellow leader, but..."

"He's certainly no Grover," Luna said.

Celestia smiled. "That he isn't."

She took another sip of her tea. Her eyes settled on something curious.

"Is that a new necklace, Luna?" Celestia asked her, gesturing towards the thin chain that wrapped around her neck and disappeared beneath the neckline of her dress. "I don't think I've seen you wearing one before."

Luna smiled, her free hand drifting to her breast. "Oh, yes. But it's not anything worth concerning yourself with, dear sister."

Celestia blinked. Her mouth opened slightly, as if she was going to say something, but closed again.

She frowned. "I'm sorry, I seem to have lost the thread of conversation. What were we discussing?"

"The preparations for the Summit," Luna said. She fixed her sister with a worried look. "Are you okay, sister? You seem a bit off today."

"I..." Celestia's frown deepened. "I do feel a bit... strange..."

That would be the wiltweed I put in your tea, Luna thought to herself. Not like Celestia needed to know that.

Celestia's hands had begun to shake. Abruptly, she set her teacup down and stood up, leaning against the table for balance.

Luna gave her a little push with her magic, enough to upset her footing but not enough to be directly noticeable, and Celestia stumbled. She caught herself by the edge of her chair.

"Sister!" Luna said, standing herself. "Are you alright?"

"Perhaps not," Celestia admitted.

Luna circled around the table and slipped her arm around Celestia's shoulders, letting her lean on her for support.

"Let me take you back to your room, dear sister. Obviously you need a rest."

"I..." Celestia's expression clouded for a moment. "Yes, okay."

She smiled, weakly. "Thank you, Luna."

By the time they had reached the door to Celestia's bedchambers, Celestia's condition had improved, though not by much. She no longer needed Luna to support her, but she stuck close to her side just in case.

As they approached the room, the two door guards snapped to attention.

"My sister is feeling unwell," Luna told them. "I will be staying by her side tonight."

"Should we fetch the royal physician, your highness?" The guard on the left asked.

"No need; it is nothing serious. I will call for her should her services be required. Unless I do, no one is to disturb us."

"Yes, your highness."

The guards opened the door for them, and Luna led her sister inside.

The doors fell closed, and Celestia continued forwards. Luna, however, first made sure the doors were locked. Her horn flashed, and a set of wards applied themselves to the door and walls. Soundproofing charms—Luna didn't want the guards outside hearing. With another flash, a cloth bag appeared at her side; she set it aside for the moment.

Preparations complete, she turned around to see her sister, leaning against one of the high posts of her lavish bed. Celestia's room was large and spacious, with three great windows set into the back wall, allowing the light of the stars to softly illuminate the room.

"Feeling better, dear sister?" Luna asked.

Celestia took a deep breath.

"A little," she said. "I think it's passing, whatever it was..."

"That's wonderful to hear," Luna said. She placed her hand on Celestia's shoulder. The older sister looked up at the touch.

"Teatime, dear sister."

Celestia's eyes unfocused. Her posture relaxed, her expression fell blank and her breathing grew even.

Luna watched her sister carefully. She'd returned to the trance Luna had left her in, several days before—that was good, though somewhat unexpected. But had she retained her memories?

"What is obedience, sister?" she asked.

"Pleasure," Celestia responded. Luna grinned. She had her. Luna licked her lips in anticipation as her hypnotized sister stood obediently before her, awaiting her next command.

Time to begin.

"Strip for me, sister."

Celestia hesitated... but just for a moment. Obedience was pleasure, a voice—her own voice—reminded her, whispering in the back of her mind.

She bent down, took the soft material of her gown between her fingers and slowly pulled it up, revealing first her ankles, then her thighs, and then her chest as it was pulled over her head. Celestia clung to it, nervous, but Luna nodded to the side and the dress was discarded.

Celestia's hands moved next to the straps of her bra. Her undergarments were a light pink; they fell away in mere moments, releasing their bountiful treasures. She stood there, naked and shivering, and it occurred to Luna that she hadn't seen her sister entirely nude since they were children.

She beckoned Celestia forwards, away from the bed and her discarded clothes, until she was in the middle of the floor. Luna circled around her, drinking in the view.

"I'm going to teach you something wonderful tonight, dear sister," Luna declared.

Celestia said nothing, her eyes simply following Luna's movements.

"Tonight, I'm going to teach you who you belong to."

Luna stepped in closer, moved around to her sister's back. She ran her fingers up Celestia's thighs and over the shapely curvature of her ass, and then, gently, she took Celestia's hands by the wrists and guided them behind her back.

"What is pleasure, sister?" Luna asked, mirroring her earlier question.

"Obedience," Celestia replied.

Luna's horn lit. The bag she had summoned opened, and a length of black fabric, no wider than two fingers, slithered out. Luna pulled it through the air, letting it snake past Celestia's face, let it brush against her cheek as it flew so she could get a good, long look at it.

"Obedience to me," Luna said. She brought Celestia's arms into position, forearms together, the fingers of each hand resting against the other arm's elbow.

"And if obedience to me is pleasure," Luna continued, her voice dropping to the gentle, even cadence it had adopted on the balcony previously, "if giving up your will to me is pleasure... then what must it feel like to give up your body, as well?"

Celestia didn't understand what she meant, at first—but then the fabric slipped around her wrists.

It slithered up her forearms, wrapping them tightly together. The material was smooth, and soft against her skin—but it was strong. She could feel that as it tightened down, not enough to hurt, but enough to tell her that it wouldn't be coming off any time soon.

Luna stepped in close, pressing her own body against Celestia's back. Her arms wrapped around her, the fingers of her right hand beginning to trace slow circles around her sister's bare middle at an even, familiar tempo. Her other hand hugged Celestia to her, resting just under her breasts.

Celestia's vision began to lose focus.

"What is being bound, relinquishing control of your body, if not a fuller expression of obedience?" Luna asked the air, as her magic pulled tight the knot that held the fabric in place.

A blush came onto Celestia's features that hadn't been there before.

"And doesn't it feel so nice," Luna said, her fingers spiraling lower, "to let me have you? To let me bind you, to so thoroughly display your obedience?"

Celestia nodded, as Luna's fingers reached her nethers.

"If obedience is pleasure, then to give yourself over to me like this must be pure bliss," Luna murmured into her ear. Her hand slipped over her sister's lower lips. They were moist.

"Your body belongs to me, Celestia," Luna said, pressing gently against the folds. "To do with as I please."

She pressed her palm against Celestia's skin, letting her middle two fingers hang tantalizingly close to her entrance.

"And you love it," Luna continued, "because pleasure is obedience."

"Pleasure is obedience," Celestia said back, automatically.

"And to be bound is a symbol of that obedience. Say it, sister."

"To be bound," Celestia repeated, "is a symbol of obedience."

Luna ran her middle finger up the length of Celestia's cunt, stopping just short of her clit. Celestia shuddered against her.

"To be bound is to let me take possession of your body."

"To be bound is to let you take possession of my b-body."

Another stroke up Celestia's marehood.

"To give up your body to me is bliss."

"T-to give up my body to you is bliss," Celestia moaned out. "Nnn..."

"To be bound by me is bliss."

"To be bound by you is bliss, sister."

"To be bound is to be obedient." Luna's thumb brushed against the hood of her sister's clit.

"T-to be bound is to be obedient!" Celestia gasped out.

"And obedience," Luna said, bringing everything full circle, "is pleasure."

"Obedience... is pleasure."

Luna sank two fingers into her sister's thirsty cunt.

Celestia gasped, her entire body quaking under the sensation.

"My, sister. We are needy today, aren't we? Did you miss my touch that much?" Luna said, curling her fingers up at the first joint. Celestia let out a short squeal as the invading digits began to dig into her in repeated, even motions. At the same time, Luna's other hand began playing with her breast, squeezing and kneading it to that same, mesmerizing tempo.

Celestia's head titled back, and her eyes raised to the ceiling. Her breaths were short, quick, becoming quicker with each stroke.

"Ah-nnn..." she moaned. "L-Luna..."

"Do you want more, sister?" Luna asked, grinning like the devil as she continued her ministrations. The question was punctuated by another brush of her clit.

"Yes!" Celestia gasped. "P-please!"

Luna's horn lit. The bag she had brought with her opened once more, and a series of belts and straps flew out of it. They were made from smooth leather, or something that looked like leather, and the low light played off of their surfaces.

She let them lazily snake their way over, drawing them past so Celestia could see. She felt her sister's marehood quiver, and grinned.

The first belt was wide, and short. It wrapped itself around Celestia's ankles, pulling them together and tightening down. Another pair, these thinner, snaked their way around her thighs, biting gently into the flesh around her cutie mark. They pulled tight, and Celestia let out another moan as her cunt was constricted around Luna's playful fingers. The dark black material stood out proud against her pale coat.

Magic took hold of Celestia's wings, folded them tightly against her back. Twin belts slipped around the second joint of each, binding the two halves of the wing together and preventing them from being spread. A second set of belts then wrapped around Celestia's chest, one over her bosom, the other sliding under, binding both her arms and her wings firmly behind her.

Celestia moaned as Luna's fingers withdrew. The princess of the night stepped around to her sister's front, examined her handiwork. Her sister was completely bound, immobilized, and helpless before her.

Perfect.

Well, almost. Something else floated from Luna's bag, falling heavily into her palm. A simple bit gag, secured by a set of straps that wound under the muzzle and around the back of the head. Old-fashioned, perhaps, but Luna always had enjoyed the classics.

"Who does your body belong to, sister?" Luna asked.

"Y-you, sister," Celestia gasped.

"You're such a fast learner, Celestia."

Luna pressed two of her fingers—still wet with her sister's juices—against Celestia's lower lip, then forced them into her mouth. She could feel Celestia's tongue in there, brushing against her fingertips. Gently, she pulled her sister's mouth open, inserted the bit, and pulled her fingers away, a thin trail of drool following them.

"Bite," she commanded, and Celestia did so. The straps wound around her head and muzzle and were tightened down by the glow of Luna's magic.

Luna reached out, cradled one of Celestia's breasts in her hand. The bindings around her chest forced them outwards, making them appear even more luscious than they already were. She rubbed her thumb across the nipple, and Celestia shivered.

"You're beautiful, sister," Luna said, drawing her hand back.

There was just one piece of the ensemble left, and Luna had it in her other hand.

It was an inhibitor ring, a wide-banded circlet of black iron with ancient runes engraved across its surface. It hinged at the back, and a clasp at the front held the keyhole which would lock it in place.

The clasp was shaped like a crescent moon.

She held it out to her sister, letting it rest heavy on her palm. "Do you know what to do with this, sister?"

Celestia nodded. Her horn lit a golden yellow, and her aura engulfed the ring. It snapped shut and levitated up, above her head, stopping just an inch above her horn.

"Good girl," Luna said with a smile. "Put it on, dear sister."

The ring slid slowly Celestia's horn, coming to a rest near the base. Immediately, her magic aura flickered out.

Luna reached under the collar of her dress and pulled up the chain which Celestia had noticed earlier. Hanging from the end of it was a tiny silver key.

She slipped the chain over her head, let it hang from her fingers. Celestia's eyes had focused on the key, which swung back and forth under her palm.

"One twist of this key," Luna said, "and you will be helpless. Your body will belong to me. Totally..."

Luna's hand drifted forwards. The backs of her fingers pressed lightly against Celestia's collar bone, traced downwards between her breasts.

"Utterly..."

Her caress continued down her stomach, brushing past her navel.

"Mine."

Her touch brushed once more over Celestia's marehood, wet and needy. Luna's fingers came away damp; she made a show of placing their tips in her mouth, licking them clean.

"You want that," Luna said. "Don't you, sister?"

Celestia nodded, letting out a whine past the gag.

"Good girl."

The key twisted in its keyhole, and Celestia was hers.

Luna smirked. She stepped back, and her sister sagged at the new distance between them. Celestia knew what she needed.

But Luna had other plans.

"Wonderful," she said. "You've done so well, Celestia. But now... "

She trailed her fingers down Celestia's cheek. Her index finger slid under her chin, tilted her head up so she was looking directly at her.

"...awaken from your trance, dear sister."

Celestia's eyes closed. When they re-opened, the difference was clear—before, she had looked tired, content. Now, her eyes were alert... and quickly settled into panic, darting around, trying to comprehend where she was and why.

She began to struggle. She tried to lift her arms, but the belts held them firm. She tried to spread her wings, but that had been taken from her, too. She tried to speak—but the straps around her muzzle held her jaw firmly clamped around the bit. All she could get out was a muffled "Mmmph!"

Her eyes flicked to Luna, questioning and frightened. A mighty blush had broken out in her cheeks. Luna relished the sight.

"Hello, sister," she said, softly. Confidently.

Celestia tried to say something, but it was lost to the gag. Still, the intent was clear.

"Untie you?" Luna chuckled. "Why would I do something like that, sister? You were the one who asked me to do it."

She gestured to her sister's crotch. "And clearly you've been enjoying it too, so I don't know why you'd want to stop now."

Another bark through the gag.

"Why?" Luna echoed. Her grin grew devilish. "Isn't it obvious? Revenge, my dearest sister."

Celestia tried to walk, but the belts around her legs held firm, and, eyes flying wide, she began to topple forward...

...only for Luna to catch her in her arms.

"Careful, sister!" Luna grunted. "We don't want you breaking that pretty face of yours. Not yet, anyway."

Gently, she lowered her sister to the ground, into a kneeling position.

"Don't look at me like that, Celestia," Luna said, noting her sister's glare. She'd seen that look before. "You owe me this much. Don't move, dear sister."

Celestia froze in place (much to her own shock, given the look in her eyes), and Luna stood up.

"Really, sister, a thousand years on the moon? Alone? Did you think I was just going to forgive you for that?"

She walked over to the bed, retrieved her bag.

"No. I've been planning this since before my return. It was a very different plan at the time, of course; I hadn't factored little Twilight and her friends into the equation, but..."

Celestia's head jerked up at the mention of her pupil.

Luna set the bag down beside her sister's shaking form and squatted down in front of her. Reaching out, she cupped Celestia's chin, forced her to look at her.

"I'm going to turn you into my willing slave, Celestia," Luna declared. "And you're going to repay me for every minute of my banishment. You can understand that, can't you?"

Celestia's look could have melted steel... but there were also tears welling up in the corners of her eyes. Smiling mischievously, Luna darted in, kissed her sister's gagged lips, the glare disappearing in an instant and a look of shock tanking its place.

"Of course, being such a good sister," Luna said, drawing back, "you'll do whatever it takes to make me happy, right?"

She stood back up, circled around behind Celestia.

From the bag, she withdrew two items. She'd picked them up in Canterlot, in one of the stores that only opened at night. She'd been under a guise at the time, of course, but—well, she'd been pleasantly surprised, to say the least. Her ponies had been busy, these last few centuries.

She planted a sandaled foot on the back of Celestia's head and forced her to the floor, leaving her ass stuck up into the air. Luna was presented with two holes, one already wet with lubrication.

Out came the toys. The first was larger, and shaped like a stallionhood; the smaller bulbous, and flanged. Each was a dark black, the same color as her restraints. The back of the plug had an emblem of Luna's moon painted onto it. It matched the one around Celestia's horn.

She pressed the larger of the two toys against her sister's folds, brushing against her clamped-down legs. Magic spread her lower lips to accommodate its head. At the same time, the other toy floated up and pressed against Celestia's ass, prying the tight little hole slightly open.

Celestia's breathing became more panicked. Her eyes darted around, trying to see what Luna was doing, but she couldn't move her head, stuck as it was being ground into the marble.

Luna let the moment hang, longer, longer, and then...

With one quick thrust, both toys forced their way into their respective holes. Celestia shrieked into the gag, her eyes wide in shock, pain, and pleasure.

"Mmm, so tight, sister," Luna teased. "How long have you gone without a good rutting? A century? Two?"

She removed her foot from Celestia's head, but the mare remained where she was, unable to move under her sister's command. Wrapping her hands around Celestia's shoulders, she pulled her back up to a sitting position. Celestia was crying properly, now, she noticed. Good.

Conjuring another belt from within the bag, this one with clips on either end, she affixed one end to the belt over Celestia's breasts, looped it around under her, and affixed it to the back side of the same. Tightening it down, the thin black material disappeared between her legs, pushing the dildo in deeper and eliciting a second, quieter squeal.

Luna slipped her arms around her sister's shoulders, leaned in close enough that the material covering her own breasts pressed against her captive's bound wings. "Enjoying yourself, sister?" she murmured.

When she got no response, she gave the belt holding the toys in place a tug, eliciting a gasp. "It's rude to ignore a question, Celestia," Luna purred. "I said, 'are you enjoying yourself, sister?'"

Fearful, Celestia shook her head.

"No?" Luna sounded almost disappointed. "Well, I'm sure you will. After all, the night is still young..."

One hand drifted down, traced the outline of the toy in her sister's snatch. She called upon her magic, not to cast a spell, but to activate the enchantment already woven into the material of the toy. Celestia gasped as the dildo began to vibrate, first slowly, then quickly picking up speed. It would change intensities once every few minutes, the deviant shopkeep had said. "To keep them on their toes."

Her ponies had come up with such clever things during her absence.

Celestia's eyes clamped shut, and her head fell back as she moaned into her gag.

"See?" Luna said. "I told you you'd love it."

She pushed the thing in deeper, held it there with her fingers, and got another moan for her troubles.

"Unfortunately, as much as I would love to keep playing with you until you break, sister," Luna said, letting up the pressure, "I have duties I must attend to in the dreamscape."

She stood up, leaving Celestia kneeling on the floor at her feet. Her sister's eyes were wide, looking at her in panicked confusion.

"But I'm sure you'll be fine on your own, won't you, Celestia?"

She bent down, brought her muzzle to Celestia's ear.

"Just don't forget," she whispered, voice heavy and mischievous. "You can only come for me, dear sister."

Straightening up again, she ignored her sister's cries into the gag. She turned away—but paused. A devilish grin spread across her features.

Turning around, she slipped the key to the inhibitor ring off of her own neck... and draped it over Celestia's.

"Have fun," she said, turning away one last time and leaving Celestia a quivering, damp, moaning mess behind her.

She laid down in Celestia's massive bed, letting the silk and cotton pool around her, and closed her eyes.

Her eyes opened again, a moment later, but not to the sight of her sister's bedroom.

The dreamscape took on many forms, depending upon the state of her ponies' collective unconscious. Today, it was a vast beach that stretched off forever, an equally infinite ocean lapping at its shores. The skies were orange and purple, though there was no sun to be seen, and the water reflected this.

Luna's bare feet left footprints in the wet sand as she walked. A flash from her horn, and hundreds, no, thousands of doors appeared before her, stretching off to the horizon. Behind each of these doors, Luna knew, was a dream.

And behind some of them, she also knew, lay nightmares. She could feel them, the afflicted ponies' minds calling out to her for help. And she would help them, soon enough.

But time meant little in dreams, and there was one pony's mind in particular she planned to visit tonight. Nightmare or not.

The doors slid past, at a blinding pace, until at last the one she was looking for appeared. It settled into the sand at her command. Emblazoned upon it was a six-pointed star.

She wrapped her hand around the doorknob and pulled it open.

Luna opened her eyes.

The first thing that hit her was the stench of her sister's arousal, thick and heavy in the air. She breathed in deeply, savoring it.

By her own estimate, she'd been in the dreamscape for several hours. Grinning in gleeful anticipation, she sat up and turned towards where she'd left her sister.

Celestia sat in a pool of her own juices. They poured out of her stuffed hole, around the dildo, leaving sticky trails in their wake on their way to the floor. She hadn't moved, but her eyes, rolled up into her head, had glazed over. Saliva dribbled down her chin past the gag, mixing with the streaks of tears running down her cheeks. Her breaths were deep and labored.

Luna's tongue slid over her lower lip. "My, sister," she purred. "You've held out so well..."

Her only response was more ragged breathing.

"Not that you had much choice in the matter." Luna slid off the bed and strode over to her sister, her black dress trailing along behind her. She knelt down, ran her fingers through Celestia's mane.

"You're such an obedient little pet, Celestia. I'm proud."

She pushed the belt around the toys to the side. The dildo slid out with an audibly wet noise; the thing was drenched, a trail of nectar stretching after it as Luna pulled it away, as if unwilling to give the toy up.

"Hah... a-ah," Celestia gasped as the thing was dislodged fully, her glistening marehood now fully exposed to the cool castle air. Its lips were puffy and stressed from the hours of abuse they'd just suffered, but the night wasn't over yet.

Luna's horn glowed, and the straps restraining Celestia loosed themselves, sliding sensually across her pale skin. The gag undid itself and was gently extricated from her mouth.

The plug in her ass, however, remained where it was.

"Well, sister?" Luna asked. "How do you feel?"

Celestia's mouth moved, but all that came out was half-formed gibberish. There was no room for thought left in her head; hours of pleasure and denial had driven it out.

Luna chuckled. "Just what I wanted to hear."

She placed her fingers on Celestia's sternum and gave her a gentle push, sending her sprawling to the ground. Another flash of her horn, and Celestia's wrists were pinned to the marble.

"I could take you now, sister," Luna said, walking her fingers down Celestia's chest. "Or would you prefer I leave you like this? Miserable, unsatisfied..." She saw the growing look of panic in her sister's clouded eyes, and she had to fight the urge to start taking care of her own needs right then and there.

"I could tie you up again," Luna continued, trailing her fingers across Celestia's stomach, playing with her. "Put the toys back in. It would be easy enough to impersonate you; I could keep you here for months..."

Luna's cruel touch came so very tantalizingly close to Celestia's needy folds, but diverted at the last second, tracing a line down the inside of her thigh, instead.

"N-n-n-n-n—"

"I wonder how much of you would be left," Luna asked the air, "after a year?"

Celestia shook her head emphatically, her long hair, normally so beautiful but now matted from sweat and sex, becoming even more unkempt. "N-n!"

"Oh?" Luna said, feigning surprise. "Then you'd prefer to let me ravage you? I am the only one who can give you release, after all... but think of your image, sister. Surely it wouldn't do for a crown princess of Equestria to let herself be used in such a manner?"

Celestia bucked her hips at her. Tears rolled down her cheeks.

"I see," Luna said, smirking. "Then remember, Celestia: you begged for this."

She slid her hands under Celestia's knees and pulled her up gently, let her sister's legs fall over each of her shoulders. Her arms wrapped around them, hands spreading her thighs, supporting Celestia's weight but still leaving her upper back pressed into the ground. Her now-unbound wings spread instinctually, her pristine feathers drawing trails through their owner's stale fluids.

Luna bent her head down. The stench of her sister's arousal was overpowering as she brought her head between Celestia's legs. She let her muzzle draw agonizingly close to the red, puffy folds—but held back, instead looking down, into her sister's eyes.

Celestia's gaze was lazy; unfocused. "Look at me, sister," Luna commanded.

With some effort, her eyes drifted to Luna's face.

Luna kissed the inside of her sister's thigh, sucking the skin between her teeth and giving the sensitive flesh a little nibble. Celestia moaned at the tease, and another gush of fluid came bubbling up from between her folds.

Sear this image into your mind, Celestia, Luna thought. I want to see it in your dreams tomorrow.

Luna's tongue darted forward. The taste of her sister filled her as she ran it up the inside wall of Celestia's marehood.

Celestia jerked, but Luna held her firm as she went in for another taste, slowly trailing her tongue up the other side, savoring it. Celestia howled, even the slightest touch an agonizing jolt of ecstasy after being kept on edge for so long.

Luna's tongue traveled bottom-to-top, slow, even motions, rubbing and prodding as it explored her sister's dripping caverns. Celestia's tongue lolled out of her mouth. Her hands grasped and ungrasped at nothing, still pinned to the ground by Luna's magic. Her body jerked again as Luna flicked her tongue upwards, tracing a teasing circle around her clitoris before descending back down.

Celestia's gasps turned to squeals. Luna could feel her getting closer, closer, her folds clenching around her eager tongue. Up to the clit, just for a second, then back down again. She increased the speed of her movements, pushing Celestia closer and closer to the edge, letting her hang there, one moment, two moments, and then...

Luna slid her tongue upwards, kissed Celestia's clit. Her teeth squeezed the little nub and Celestia screamed as she finally came.

Her body spasmed, twisting under Luna's firm grasp. Her thighs tried to squeeze together, but Luna held them apart, letting Celestia's marecum flood out. Luna lapped it up, and Celestia came again, her back arching as she squealed.

Now, at last, Celestia was spent, falling limp in her sister's grasp, her chest heaving.

Luna released her magic and her sister's legs. Celestia collapsed to the floor, a sticky, sweaty mess. There was nothing regal about her now, Luna thought. She looked like a back-alley whore, used and then discarded.

The thought made Luna very, very hot.

Celestia's dry gasps shook Luna from her thoughts. Turning around, she retrieved the last item from her bag of tricks—a canteen of water. Unscrewing the lid, she knelt down and brought it to her sister's lips.

"Drink up, sister," Luna said. "Quickly, before you pass out."

Celestia dutifully gulped down the offered water, then collapsed again. This time, her eyes fluttered closed and stayed that way.

As the last of her consciousness faded, Luna bent down and whispered into her ear.

"Teatime is over, dear sister."

And with one last moan, Celestia fell unconscious.

At the back of Luna's mind, she felt a light tug; turning her attention to the window, she saw her moon slowly descending towards the horizon. It was dawn.

Closing her eyes, she reached out with her magic. Not to the moon, which was already dutifully on its way. No, she reached past it, to the great, flaming ball of plasma that sat below the eastern horizon.

She gave it a pull. It was resistant, at first, but quickly settled on its track across the heavens. The sky turned gray with the dawn, and Luna smirked. The sun already obeyed her. Soon, so would its master.

Turning her attention back to the mess on the floor, she gently lifted her sister up in her magic. Her head lolled. Luna chuckled.

"Come along, sister," she said, turning towards the door that lead to Celestia's private bath. "Let's get you cleaned up."
