Chapter 1

Princess Luna hesitated a few moments before reaching out with her magic and opening the crystal doors that led to the moonlit gardens. She usually enjoyed the moonlit gardens. They had been built and designed specifically for her. Celestia had the sun gardens. When she had returned from her banishment, Celestia had insisted that she have the castle gardeners design a garden specifically for her.

At first Luna hadn’t cared that her sister had her own gardens, but Celestia made a concerted effort to make sure that her sister was equally represented in all things. It was her way of showing Luna that she cared. Luna appreciated the gesture of course, but when her gardens were completed and she saw what the castle gardeners were capable of, she was very glad that her sister had convinced her to commission them.

To say the moonlit gardens were beautiful would be an insult. Everything about them was absolutely majestic. There was a waterfall whose headwaters originated above the castle and cascaded down a gentle slope into a slow running stream that ran around the entire perimeter of the gardens. The gardens were massive and included dozens of varieties of flowers of all imaginable colors that only bloomed in moonlight.

Hedges surrounded the perimeter of the gardens, raised upon retaining walls made of moonstone. There was a huge water fountain that made up the center of the gardens, the likeness of herself, Celestia, Cadance, and Twilight carved into the stone and made into a four spouted water fountain with a large reservoir. Pedals of the most delicate moonflowers floated on the water along with the tops of the moonflowers themselves, the center of the flowers glowing with a slight ambience.

There were eight rows of perfectly proportioned flower beds heading up to the water fountain; two on each side that met in the middle with a large walkway between each one, ending about ten feet from the edge of the fountain so that a pony could walk through each isle of flowers and enjoy each type one by one.

And around the inside perimeter of the stream that ran around the entirety of the gardens were many flower beds, each with a unique type of flower that bloomed only in moonlight. Luna’s moonlit gardens were quite bland if seen in the daytime. It was only at night that they showed their true brilliance.

Luna stepped forward reluctantly, each step heavy as she marched forward towards the inevitable. Had she been walking inside, the sounds of her hooves on the tile would have carried throughout the corridors. As it was, however, her hoofsteps were muffled by the silk moss that lay beneath them, the pleasant moisture of the moss lost to her as she thought about what she was about to do.

Had she been on her way to deal with a courtroom full of disgruntled dignitary ponies, she could have handled it. Quelling the nightmares of scared ponies? She could’ve dealt with that too. But what she was being forced to do now was beyond what she was capable of.

Her sister – Celestia – had summoned her. She had received the summons as she was just getting out of bed. Such a summons from her sister wasn’t unusual, but the place where she had requested to meet her was. If she had been summoned to a meeting in the wardroom, or the throne room, or even her sister’s bedroom, she could have handled it. But being in the moonlit gardens like this was not something she could handle. Not with…her.

She felt a light blush on her cheeks and she chastised herself. Not now! Not tonight! But what other time was there? It’s not like there was ever an appropriate time to admit those kinds of feelings.

She furrowed her brow and looked forward resolutely. She had to get control of herself! She was acting like a foal. No matter what happened, she wouldn’t blush. She would approach this situation with the utmost professionalism – like a Princess should.

As she made her way around the fountain in the middle of the gardens, she finally laid eyes on her sister. Celestia was looking down at a bed of blue nightflowers – Luna’s favorite. She didn’t know what it was about the blue nightflowers; whether it was the softness of their pedals or the way their pistils caught the nighttime dew, but they were absolutely beautiful to her. As she observed the scene before her however, her eyes weren’t on the nightflowers.

Nopony could argue that Celestia looked absolutely radiant under the brightness of her sun. But to Luna, everything looked more beautiful in the moonlight - her sister being no exception. Like always, Celestia’s mane was in motion, moving in a non-existent wind despite the fact that she was standing still. But the way her coat shined in the moonlight, the way the ambience of the nightflowers reflected off her mane, and the way the luminescent pollen swirled all around her as the nightflowers spread their seeds made the image of her absolutely captivating.

By some miracle she hadn’t blushed at the scene before her, still steeling herself as she walked towards her sister. She wasn’t sure whether Celestia hadn’t noticed her or was just ignoring her, but she made it all the way up to her and began to speak before Celestia turned to face her.

“Sister.” She said simply, no emotion in her voice.

“Luna!” She said warmly as she turned to face her. “I see you got my letter.”

As Celestia turned to her, she found herself speechless. It took her a moment before she found her voice again.

“Y-yes…” She said softly, her eyes suddenly downcast.

She couldn’t look at her sister anymore. If she did, she didn’t know what she might do.

“Is something wrong?” Celestia asked, concerned.

“No!” She said, a little too loudly as she looked back up at her and gave her a big, fake smile.

Celestia gave her a strange look before continuing.

“I thought that we might spend some time together tonight.” She said.

When she received only a blank stare in response, she continued.

“In an environment that you find comfortable.” She added.

Celestia’s voice seemed to be conveying a suggestion, but it felt more like a command to Luna. She hadn’t been able to say no to her sister for quite some time now, always afraid that if she said no, her sister might pry further into what she was actually feeling.

“O-okay…” She said, her ears drooping.

Celestia smiled and turned around to face the nightflowers once more. Luna reluctantly walked up beside her, trying to focus on nothing but the flowers and failing miserably. She kept stealing glances at her sister, unable to stop herself from doing what she knew was bad for her.

She finally looked forward at the flowerbed once more, using all her discipline to resist looking over at her sister as she tried to enjoy the nightflowers. The sound of her sister lying down caused her to involuntarily look over at her as she got comfortable on the grass below.

“Come lay with me, Luna.” She said, looking up at her with a gentle smile.

Luna could feel a light blush on her face and she mentally chastised herself. She laid down and looked forward, trying to forget who she was lying next to. That lasted for all of about ten seconds until she felt her sister’s wing wrap around her and she lowered her head, trying to cover the blush that was now so intense she could practically feel the heat radiating off her fur.

She felt the grip of her sister’s wing loosen as she squeezed her eyes shut, and she almost jumped out of her skin as Celestia lowered her neck so they would be face to face.

“What is it, Luna?” She asked, her voice full of concern.

“N-nothing…” She said, turning away from her in a vain attempt to hide her blush. “Nothing…”

The second time she spoke it was barely above a whisper, which in and of itself was concerning. But when she turned her body away from her, Celestia’s concern intensified even more.

“Luna, are you hurt?” She asked, turning as well and putting a hoof onto her back.

“No!” She said frantically, looking back at her, her blush still covering her face.

Celestia stood up and laid down next to her again, looking down at her in concern. Luna looked away again, but didn’t bother to turn her body that time.

“Did I do something wrong?” She asked.

“No.” She said, her voice abrupt.

“Please, Luna, tell me what’s wrong.” Celestia said, her caring voice sending shivers down her spine. “You know you can tell me anything, right?”

There was a long silence between them as Luna continued avoiding her sister’s eyes, desperately hoping that her blush would go away.

“Anything?” She asked, not turning to look at her. “Do you really mean that, sister?”

“Of course, Luna.” She said, putting a hoof on her back in a comforting gesture. “I want to know what’s troubling you.”

There was another long silence as Luna thought.

“It’s…not something I can talk about with you, sister…” She said quietly.

“You’ve been acting very strange these past few weeks, Luna.” She said. “I know you’ve been avoiding me. I need you to be open and honest with me, sister. There’s nopony I trust more than you, and I hope you hold me in the same regard.”

“I do!” Luna exclaimed, looking into her sister’s eyes. “I trust you completely, sister. I just…”

Luna sighed, closing her eyes. She couldn’t look at her sister any longer, but she didn’t want to turn away from her anymore. She knew that Celestia was concerned about her, and she didn’t want her to think that she didn’t appreciate her concern.

“I…can’t…” She finally said, opening up her eyes and avoiding her gaze.

“Why?” Celestia asked.

Her question surprised Luna. She supposed the question was a logical one, but she still had no way of answering it. It took her quite a few moments to come up with an answer that didn’t give anything away, but also might convince her sister to drop the matter.

“Y-you won’t like it.” She said.

“This isn’t about me.” Celestia said reassuringly. “This is about you. You need to get this off your chest, Luna. It’s hurting you keeping this bottled up inside.”

Luna could feel tears run down her face as she looked down, unable to meet her sister’s gaze. Her tears hadn’t gone unnoticed by Celestia, who leaned her neck down to nuzzle against her affectionately. As Luna felt her sister’s soft fur on her cheek, she leaned against her instinctively and started to cry. She cried in silence for a few moments before breaking out into a quiet sob, nuzzling into her sister’s neck as she rubbed against her, tears staining her pristine white fur.

Celestia hugged her sister against her form, comforting her as she released the sadness that she had been carrying around the past few weeks. She had cried many times since she had realized her feelings, but she hadn’t cried in several weeks. It felt good to cry again, and even better to be in the embrace of the pony she loved. But it was a bittersweet feeling, as she knew that as soon as she stopped crying that everything would all go back to the way it was before. She would never be able to tell her sister the truth.

“There, there.” Celestia said, nuzzling against her comfortingly as her sobs started to die down. “I’m here for you, Luna. I always will be.”

Luna nuzzled against her sister’s chest, taking comfort in her soft fur as she rubbed her cheek against her.

“I love you so much, sister.” She said. “I just…”

“Yes?” Celestia asked, encouraging her to continue.

Luna looked up at her sister. She wanted so much to tell her how she felt. It would feel so good to finally admit these feelings. But she knew that the relief would be short-lived and quickly replaced by horror from her sister. Their relationship would be destroyed by the terrible feelings she had. She had to keep them locked up inside of her, even if it did reduce her to a quivering mess on occasion.

“Nothing…” She said, turning to avoid her gaze once more.

She was surprised as she felt her sister’s hoof under her chin, forcing her to look up at her. As she beheld her sister’s visage in the moonlight, she suddenly felt her cheeks light on fire again, yet she was unable to look away due to her sister’s hoof.

“I know it’s something, Luna.” She said gently. “Whatever it is, you can tell me.”

Luna felt tears in her eyes again. Unable to look away, she wrapped her hooves around her sister’s neck and pulled herself forward, bringing them into a tight hug as she started sobbing again.

“I-I can’t!” She said, sobbing.

Celestia lowered her head a bit, nuzzling against her sister’s head in a warm embrace.

“Yes…you can.” She said reassuringly.

Something about the way she said it put Luna at ease. She knew it wasn’t logical. All the facts remained. But her sister sounded so sure of herself. Her confidence gave her the resolve to start. She pulled herself back, looking away from her sister as she laid down on the grass again.

“I-I love you, sister.” She said softly.

“I love you too, Luna.” She said, smiling down at her.

“No.” She said, her voice commanding as she looked directly into her sister’s eyes.

The smile left Celestia’s face, but all of her attention was still focused on her sister.

“Not like that.” Luna said, blinking as she felt fresh tears in her eyes. “My love isn’t pure like yours. It’s dirty. It’s wrong.”

“What do you mean?” Celestia asked in concern.

“I…desire you, sister…” She said, looking away from her in shame.

“W-wha…” Celestia stammered, her mouth open in shock.

Luna wasn’t even blushing anymore. She was too ashamed to blush. She wanted so much to look at up her sister, but she didn’t deserve to look at her. Her sister was pure, and her gaze was unclean. Looking at her sister after saying such a thing would be a disgrace to her sister, and that was the last thing she wanted.

Nothing really surprised Celestia anymore. After more than a thousand years of ruling Equestria, she had seen just about everything. And she had rejected more than her fair share of hopeful suitors. But for the first time in hundreds of years, Celestia didn’t know what to do.

Rejecting some hopeful mare or stallion that she didn’t know was one thing, but Luna was her sister. She couldn’t just brush her off and expect everything to go back to normal afterwards. She had become an expert at rejecting ponies over the years, but none of the techniques she had learned could be applied to Luna.

Her heart ached for Luna. She felt so sorry for her. Not only did she obviously have feelings for her, but she had been so reluctant to share those feelings that she practically had to drag the confession out of her. To simply reject her now would be far too cruel.

“I know these feelings are wrong, but I can’t help it, sister!” She said. “I want us to have so much more than we do. Every time I’m around you, I feel like there are a million butterflies in my stomach, and every time we’re apart I feel like there’s a knife in my stomach. They say that love comes from your heart, but I think it comes from the stomach, sister.”

Celestia laughed at that. Her sister’s laughter surprised her, and Luna found herself smiling weakly, feeling a little better about things.

“I-I’m sorry, Luna, but that was funny.” She said, chuckling. “Love can be confusing and unpleasant sometimes, especially when it’s unrequited.”

Her sister’s response did little to lift her spirits, and she found herself looking up at her sister seriously.

“So, um, now that you know…” She said softly, resisting the urge to look away. “H-how do you feel about me?”

Celestia looked down at her seriously.

“Luna…” She said sadly. “I love you more than I can say, but…”

She paused as she saw the dejected look on her sister’s face. She couldn’t reject her like this. She just couldn’t.

“I-I need some time to think about it, okay?” She asked hopefully.

She immediately felt guilty as the little white lie left her lips. She didn’t want to get her sister’s hopes up, but she didn’t want to crush her by telling her that she had never thought of her that way.

“Okay, sister…” She said, sighing in relief as she leaned against her and closed her eyes.

Celestia leaned down and nuzzled against her affectionately.

Luna let her body completely relax as she felt the tension leave her. It hadn’t been the enthusiastic reciprocation of love she had hoped for, but the very lack of a stern denial from her sister filled her with hope. She would settle for anything even close to acceptance from her sister, even if she didn’t reciprocate her physical desires. As she nuzzled into her sister’s warm embrace, she felt her eyelids start to close, and before she knew it, she was fast asleep.

||||||||||||||||||||||||||||||||||||||||||||

Celestia had been a mess in court the next day. She was consumed with guilt from lying to her sister. She wasn’t doing her any favors by leading her on. It was better to let her down gently than to get her hopes up only to completely dash them in an instant. She knew it wouldn’t be easy, but she had to have a talk with her. She was making her way to her sister’s chambers, cognizant of the sounds her hooves made each time they made contact with the tile below. As she rounded a corner, she was surprised to come face to face with her sister, who also wore a surprised expression. Luna got over it quickly however, and rubbed her body against her chest, pressing against her enthusiastically.

“Calling it a night already, sister?” She teased.

Luna looped between her sister’s front legs, looking straight up at her. Celestia looked down at her in surprise.

“Actually, I was - .”

She was cut off abruptly as Luna gave her a quick, chaste kiss. It certainly hadn’t been a long, drawn-out, romantic kiss, and had she not learned about her sister’s feelings for her, she would have merely been surprised by her quick gesture of affection. However, knowing how she felt about her gave the kiss a whole other meaning, and she found herself blushing profusely as the implication.

“I know where your room is.” Luna whispered into her ear. “Just send for me and I’ll be there.”

With that she kept walking down the hall as if nothing happened, leaving her sister standing dumbstruck in the middle of the hallway as she rounded another corner. By the time Celestia got control of her body again and looked behind her, her sister was already gone. It was then that she realized that her blush still hadn’t gone away. She shook her head, still completely frazzled by the encounter. Part of her wanted to follow Luna and demand an explanation, but another part of her wondered if her offer was serious. She found herself walking quickly towards her own bedroom, rushing inside without ceremony and collapsing on her bed in utter exhaustion.

Her heart was racing in her chest. The Luna she had just encountered was completely different than the Luna that had admitted her feelings to her in the moonlit gardens. That Luna was meek, submissive, vulnerable. The Luna she had met in the hall had been daring, aggressive, and confident. It turned her on as she realized that nopony had dared to speak to her like that in hundreds of years. She looked over at her door and wondered if she really had been serious. She chastised herself for even thinking such a thing. Even if she had been serious, there was no way she could take her up on such an offer! She was her sister!

Still, she couldn’t deny that she felt a stirring in her loins as she thought back to the encounter. Without realizing it, her hoof had traveled a little too far south for comfort and she pulled it away defiantly, refusing to take pleasure in such a memory. No. She had to put a stop to this. But despite the uneasy feelings she got from the feeling of her hoof against her most sensitive of places, she did find pleasure in herself that night, memories of her sister’s aggressiveness causing her body to shake in pleasure like it hadn’t done in centuries.

|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Celestia awoke with no memory of what she’d done the night before. That is, until she felt the stickiness between her legs. She swore under her breath as she got out of bed, rushing into the shower to get rid of the evidence of her unclean thoughts. She raised the sun, trying her best to put the memory of the pleasure she felt the night before behind her. Suitably refreshed, she made her way to the dining hall, intent on putting a stop to her sister’s behavior. As much as she wanted to spare her feelings, she couldn’t allow this to continue. She opened the large, double doors and walked inside, a bit surprised as she saw her sister sitting at the table.

“Good morning, sister!” She called, waving over at her. “Care for some breakfast?”

Celestia blinked for a moment, somewhat surprised at how prosaic her sister was acting - like the night in the gardens hadn’t even happened. She walked over to the table and sat down next to Luna, using her magic to grab some of the breakfast items that covered the table and adding them to a plate which she quickly put in front of herself.

The dining hall was quite a private place. It was one of the few places which had no guards and that all servants were instructed to avoid entering unannounced. Because of this, Celestia felt at ease enough to broach the uncomfortable subject.

Celestia found herself going over the discussion in her mind.

Luna, we need to talk. She thought, furrowing her brow. No. That’s too on the nose. I have to let her down easy. But how am I supposed to do that?

“Sister, are you alright?” Luna asked, looking over at her in concern.

“Huh?” Celestia asked in surprise.

Luna’s concerned expression never left her face, and Celestia automatically assumed her usual role.

“Oh, yes.” She said, a practiced smile gracing her lips.

Celestia couldn’t help but lose her composure as Luna furrowed her brow. She knew she’d been caught.

“You can’t Princess me, Celestia.” She said flatly. “I know you too well to be fooled by your consumate smiles and your superlative words.”

Celestia sighed, slouching down in her chair. This was going to be harder than she imagined.

“Luna, we need to - ”

A resounding CLANG filled the room as Luna dropped her fork.

“Whoopsie!” She said whimsically, getting off of her chair and beginning to search for the fork.

Celestia watched her little sister as she crawled around on the floor, still in shock from the loud sound that had interrupted her train of thought. She suddenly felt grateful for the interruption however as she realized that she hadn’t really known how to say what she needed to say without hurting her sister’s feelings.

“Luna, the servants can fetch you another - ”

She stopped talking abruptly as her sister turned away from her, flagging her tail to reveal her tight pussy. She swayed her rump back and forth in a show of finding her fork, studying an empty spot on the floor with feigned interest as she made sure to give her sister the chance to behold the magnificence of her posterior.

Celestia found herself staring at her sister curiously. She’d never seen her sister’s marehood up close before. It wasn’t that she hadn’t had the opportunity, but rather that she’d never been interested enough to try and look before. Now that she was looking however, she was in awe. If there was one word she could use to describe her sister’s marehood, it would be “perfect.” Her puffy blue lips looked incredibly tight. She almost gasped as they opened slightly to reveal a sliver of pink between them. Her body finally forced her to blink, breaking the spell she had been put under. It was then that she realized that Luna was looking back at her with a smirk. She felt ashamed as she realized how long it took her to recognize her inappropriate behavior and avert her gaze from her sister.

“L-Luna…” She whispered under her breath.

She blushed furiously as she realized that her wings had fully extended without her knowledge. She reached behind herself with a hoof to try and force them down. It didn’t work very well but she had to at least try to control herself.

Luna sighed theatrically.

“Oh well, I suppose I was done eating anyway.” She said, standing up straight again.

She started trotting towards the door.

“I’m going to bed.” She said simply as she opened the door and stepped outside.

“Oh!” She exclaimed rather melodramatically. “If you need any *ahem* assistance today, just wake me up and I’ll be happy to help! Ta-ta!”

“W-wait, Luna!” Celestia exclaimed, holding out a hoof.

But it was too late. Luna had already slammed the door behind her and Celestia was left alone with burning cheeks and a very uncomfortable wingboner.

|||||||||||||||||||||||||||||||||||||||||||||||||

Celestia’s court had been even worse that day then it had been before. She had felt arousal before of course, but not in a very long time. Her sister had been so timid in the gardens during her confession, but now she was being completely unguarded in regards to expressing her feelings. Celestia had been pursued before, but Luna’s attempt at courting her was surprisingly direct and forthright. She supposed she shouldn’t be surprised. Luna had never been one for beating around the bush. Still, how much longer could these adolescent games continue? Surely, they would eventually have to sit down and have a real discussion about what they were both feeling.

But they had technically already done that. Or Luna had at least. Luna had made her feelings perfectly clear. It was Celestia that needed to make a choice. Or at least that’s what she had told her sister. In reality she had never seen her sister as anything other than her little sister, so why did the thought of sitting down and having a serious discussion with her fill her with a sense of dread? It couldn’t be that she was enjoying being courted by her sister, could it?

She’s waiting for you to reciprocate.

The thought sent shivers down her spine. How could she reciprocate? She had never been good at acting factious like her sister. How could she respond to such inappropriate attempts to court her?

Inappropriate.

Another shiver. Everything about this situation was inappropriate. Luna was her sister. The very idea of having sex with her made her both apprehensive and excited. She knew that on a purely logical level it would be very bad for her to have sex with her sister. It would complicate their relationship. It wasn’t like they could just not see each other anymore if something went wrong. They were immortal alicorns with duties and responsibilities. But maybe the idea that it was wrong was what made it so seductive.

Celestia had finally made it to her room. She opened the large double doors silently with her magic and stepped inside. Once the doors were safely shut behind her, she let herself go, visibly slumping in relief as she allowed herself to take off the mask of regality she always wore. She was exhausted.

She nearly jumped in surprise as she saw a form outside her balcony window. It took her only a moment to recognize it as her sister but it had given her quite the fright.

Luna was looking up at the stars, sitting down on her haunches as her starry blue mane moved in the ethereal wind. Celestia stood there for a moment, mesmerized by the sight. Luna truly was beautiful. She didn’t know how she hadn’t recognized it before. It was like she had been half blind. She opened the door to her balcony and stepped outside to join her.

“Luna?” She said quizzically.

Luna turned to meet her gaze, a smile gracing her face.

“I see you’ve returned.” She said. “Your court went a little over today.”

“Yes, there were a lot of ponies that sought my council.” She said. “What are you doing here?”

“I was hoping to share your bed tonight.” She said bluntly, a smirk spreading across her face.

Celestia took a few steps back in surprise.

“L-Luna, I…” She stammered nervously, averting her gaze.

Luna sauntered over to her and rubbed against her chest affectionately.

“Can we have sex, sister?” She begged. “Please? I know you’re attracted to me. You don’t get a wingboner like that from looking at a fork.”

“B-But I…” Celestia stammered as she continued stepping back, trying to get away from her horny sister.

She felt her rump come into contact with the glass of the door to the balcony as she was forced to stop. Luna took the opportunity to begin kissing her neck aggressively. She made low grunting sounds like an animal as she breathed in her scent, and Celestia found her wings fully extending in arousal as her sister focused all of her desires on her.

“I want you so badly, ‘Tia.” She said huskily between kisses. “Do you want me?”

Celestia’s marehood winked in arousal as she felt powerless to deny her sister’s desires. Celestia felt more dominated with each kiss her sister stole, and despite some feelings of trepidation, she found herself unable to push Luna away. It would be a simple matter to raise her hoof and push her aside, or to pull her away from her with her magic. Even simply asking her to stop would bring a halt to her sister’s advances. But Celestia found she didn’t want to do any of those things and simply allowed Luna to continue.

Luna was enjoying every minute as she buried her muzzle in her sister’s fur, kissing her on her neck and chest, but she wanted more. She fired up her horn, sliding the door out of the way with her magic and pushing her sister back into her room forcefully. Celestia stepped back frantically, barely able to keep up with her sister’s rapid advances and nearly tripping over her own hooves as she tried to backpedal so quickly.

She was suddenly surprised as her back hooves bumped into something, but she didn’t have long to think about what it was because Luna kept pushing. She crawled up on top of her as Celestia fell onto the bed, peppering the white alicorns face with light kisses. Luna stopped abruptly, her breath heavy as she looked down at her sister with a look of pure desire on her face.

“Can we have sex, ‘Tia?” She asked.

Celestia furrowed her brow in confusion. She thought that she had already given her consent but now that she thought about it maybe she hadn’t.

“Please?” She added, the desperation evident in her voice.

Celestia looked up at her sister in sympathy. The desperation and desire on her sister’s face made her cheeks heat up in embarrassment as she realized how much she wanted her.

“Yes.” Celestia said simply.

The affect that simple word had on Luna was immense. She brought them into a lust-filled kiss, releasing all of her pent-up desires onto her sister as she groaned in pleasure. Celestia was a strong mare, but even she didn’t want to be in control all of the time. She had taken many lovers over the years, but none of them had truly dominated her like this. As her sister rubbed her body against her enthusiastically, she suddenly realized the reason. Luna was her equal. Despite how involved she had become with her previous lovers, they still respected her authority. None of them had felt powerful enough to feel truly comfortable in dominating her. Luna was.

“Ah!” Celestia gasped in pleasure as Luna pulled her muzzle away from her, breaking the kiss.

“I’m going to make you feel good.” Luna whispered into her ear.

Luna slid down her sister’s form, peppering her chest and stomach with kisses as she got lower and lower. Celestia simply laid there and looked up at the ceiling, allowing her sister to do whatever she wanted to her. She felt a shiver go down her spine as she felt her sister’s breath against her flower. Without any further warning or ceremony, Luna pressed her muzzle against her sister’s folds, tasting her nectar.

It had been decades since Celestia had felt the touch of another pony. She had almost forgotten what it felt like. She had been unprepared for the intensity of the sensation and found herself moaning loudly in pleasure, her eyes squeezing shut and her back arching as the pleasure overwhelmed her.

Luna found herself smirking involuntarily as she heard her sisters’ moans. She wanted to make this experience as good as possible for her, so she made every effort to deliver consistent jolts of pleasure to her sister as she enjoyed the sensations.

Celestia’s breath hitched again and again as her sister continued her ministrations, the overwhelming pleasure making it impossible for her to breathe normally. Her lungs burned, but she paid them no mind, completely consumed with the pleasure washing over her entire body. Her sister gave her no respite, pushing her closer and closer to the edge. The pleasure built up inside of her until she could contain it no longer. Celestia threw her head back and squeezed her eyes shut.

“Ahhhh…Ahhhhhhhhhh!” She exclaimed, her flower spasming around her sister’s muzzle in a desperate attempt to keep it inside of her.

Every muscle in her body tensed as she experienced her orgasm, the overwhelming pleasure causing her to momentarily lose control of her body as she shook in pleasure. Suddenly her muscles released and she found herself collapsed on the bed, panting heavily.

“L-Luna…” She breathed.

“Shhhhhh…” She said, crawling back on top of her and bringing them into another passionate kiss.

Celestia could taste herself on her sister but it didn’t bother her; she was too consumed with the feeling of her sister’s lips pressed against her own. They separated for a fraction of a second every few seconds, allowing each other to breathe.

Celestia rolled over onto her side, taking her sister with her. Luna suddenly found their positions reversed, her larger sister on top of her as she took the lead. Celestia slid down her sister’s body, looking down between her legs at her perfect flower. It was agape with arousal and Celestia found herself licking her lips in anticipation.

“Y-you don’t have to, ‘Tia.” Luna said, still panting.

“I want to.” Celestia said insistently.

Without any warning she leaned forward, bringing her muzzle to bear against her little sister’s marehood. Luna looked up at the ceiling and breathed deeply, pacing herself for what was sure to be a long, pleasurable experience. As she felt her sisters tongue begin to lap against her marehood she shifted, the sensations making it impossible for her to hold still. She found herself putting her hooves on her sister’s head, more to steady herself than to direct her. Celestia seemed to take it as an indication that she wanted her to put more effort into it because she started moving more feverishly in an effort to increase her sisters’ pleasure.

Soon enough Luna found herself moaning from the intensity of the experience, her rear legs moving on their own accord as she tried to cope with the pleasure coursing through her body. Celestia paid her movements no mind as she focused on her clit, sucking on it expertly. As much as Luna had dreamed of this day, actually having sex with her sister seemed almost ordinary. More than that – it felt right. She knew that incest was frowned upon by most ponies, but she and her sister weren’t ordinary ponies. She loved her sister with everything she had and at that moment she knew that her sister cared for her in the same way.

Celestia knew that her sister was close as a rather loud moan was torn from her lips. She redoubled her efforts, doing everything she could to increase her sister’s pleasure. Luna’s reaction when she came was quite different than her sister’s. Celestia found her head squeezed on both sides by Luna’s legs as she shook violently in orgasm.

“Oohhh…Ohhhhhhhhhh!” Luna cried out, a loud, deep moan leaving her as she was pushed over the edge.

Celestia continued unabated through her orgasm, stopping only when Luna finally released her head from between her legs. Luna looked down at her with a warm smile, which she returned.

“Did you enjoy that?” Celestia asked, chuckling.

“Very much so.” Luna said matter-of-factly.

Celestia pulled herself up alongside her sister in the bed and used her magic to put the blanket over both of them. She spooned her little sister against her and embraced her tightly.

“Mmmmmm…” Luna said in contentment as she felt her sister kiss the top of her head.

In only a few moments both mares slipped into a restful sleep, content in each other’s hooves…

Celestia opened her eyes slowly. A big blue blur filled her vision. As her vision cleared, she was surprised to realize it was Luna. It took a few seconds for her mind to remember exactly what had happened the night before. Her breath hitched as the memories came flooding back to her. Luna was still sleeping, but she stirred, scrunching up her nose before opening her eyes slowly. Her experience was similar to Celestia’s, and Celestia got a certain sense of satisfaction watching the same thoughts go through her sister’s head. Unlike Celestia however, her breathing didn’t hitch. Instead she smiled widely.

“Good morning, sister.” She said happily.

Celestia’s face had originally been expressionless, but her sister’s smile was infectious and she soon found a matching smile on her own face.

Luna giggled, grabbing a pillow from the bed and pelting her sister in the face with it. Celestia snorted in surprise and struggled to sit upright. By the time she had collected herself, Luna had already rolled out of bed and was racing her into the bathroom.

“I get first dibs on the shower!” She called after her.

“Hey, no fair!” Celestia called after her.

Luna’s giggles could be heard through the locked bathroom door and she was tempted to simply unlock it with her magic, but another pressing need grabbed her attention and she nearly gasped in panic.

“Luna, the moon!” She exclaimed.

“Lower it for me, will you?” She asked nonchalantly.

“What?!” Celestia snorted indignantly. “No fair! Do your own job!”

“I’m not listening!” She called. “Winter wrap-up, winter wrap-up, la, la, la, la, la, la, la!”

“Lazy Moonbutt…” Celestia muttered.

She begrudgingly walked over to the doorway to her balcony and lowered the moon and raised the sun. Luna had already gotten out of the shower by the time she finished.

“So, are you done yet?” She asked casually.

“You know how taxing it is to do both the sun and the moon, Luna.” Celestia said disapprovingly.

“But I had to get into the shower first!” Luna complained. “That takes first priority!”

Celestia rolled her eyes.

“Just like when we were foals…” She said.

“I don’t change much.” She said simply.

She suddenly blushed, giving her sister a grateful smile.

“Thank you, ‘Tia.” She said.

“I expect you to do the sun and the moon tonight in exchange.” Celestia said.

“No, not for that!” Luna exclaimed, exasperated. “I meant…”

She lowered her voice before continuing.

“…For having sex with me.” She said bashfully.

Celestia suddenly blushed as well. There was no other way to put it. They had had sex.

“I know I was rather forceful, but I hope you didn’t feel that I pushed you into it.” She said.

Celestia looked at her in surprise.

“What?” She asked. “No! I’m a grown mare and I make my own decisions. You were rather aggressive, but it was my decision to submit to you. It was, umm…it really turned me on…”

By then her blush had spread across most of her face, but it went unnoticed by Luna, who wore a giant smile on her face.

“Really!?” She asked excitedly.

“Y-yeah.” Celestia said, smiling meekly.

“Does that mean you want to do it again?” Luna asked hopefully.

“Do you want to?” Celestia asked.

“Yes!” Luna said enthusiastically.

“Then we will.” Celestia said, smiling.

Luna nuzzled against her sister’s chest affectionately. Celestia returned the gesture before pulling away gently.

“I have to attend my court now, Luna.” She said. “Seeing as you slept all night, you’re welcome to attend.”

“I think I would like that.”

Sorry if this story isn't up to my usual caliber when it comes to my writing. I really had to rush about half of it in order to submit it in time for the contest. Here's to hoping it wasn't as bad as I think it is!
