Diaries of The Mare in the Moon
Chapter 1
Don't Panic

With a scream of rage, Luna loosed the bolt from her horn and watched it dwindle into the distance. What followed was a moment of complete disorientation. Celestia was gone. The castle was gone. All that existed was the grey, dusty ground beneath her, and the starry backdrop of her night sky. Nothing.

She fell to her haunches. Was she dead? Luna didn’t think her sister had been actively trying to kill her; up until the end Celestia hadn't even fired a spell at her. There was always the chance though, in the heat of the moment.

You’ve gone too far, Luna. Celestia’s voice in her head. Stop this, before I have to. Echoes from a conversation that had ended in nothing short of magical warfare through the stone halls.

But not now. Now she needed to focus. To work out exactly what had happened. Luna pulled off her helmet, casting it aside as she shrugged off her armour. It hit the ground with a heavy thunk, sinking slightly into the dust.

The stars above twinkled, oblivious and uncaring to her plight. At least she could draw solace in her moon, she thought. Which was, of course, when icy cold rolled down her spine, that sinking in the pit of her stomach as she came to terms with how wrong this whole situation was.

The moon was gone.

In its place was a blue orb, much larger than her moon had been. Misty clouds covered its surface; white swirls over the crystalline turquoise. It was beautiful, but all Luna wanted to do was tear it from the sky, rip it from its place for being so ostentatious as to replace her moon.

This could not be happening. The moon must still be there somewhere, it had to be. Her wings shot out, ready and willing, and after a short run she leapt into the air. Three seconds later she crashed into the ground, throwing up clouds of dust.

She couldn’t fly. Why couldn’t she fly?!

Pounding the ground beneath her in frustration, kicking up more of the fine motes, Luna came to the truth she had been avoiding. She knew that dust. Luna had found her moon.

She was sitting on it.

***

Step One: Don't Panic.

Step Two: Find out what's limiting my abilities, and stop it.

Step Three: Get off the moon.

Step Four: Don't Panic.

Luna reviewed the list she'd scratched into the moon's surface. It had gone through several rewrites (buried somewhere under the loose dust was the item 'Hit that sun-bitch in the face', which she'd ultimately decided wasn't conducive to a productive atmosphere), but she was satisfied with the finished product. It was short. To the point. Imperative.

It hadn’t taken long to discover her magic was just as restricted as her flight. Her first escape attempt had been to try teleporting back to Equestria. Back home. Luna had fixated on the blue orb above, horn sparking shakily to life, and managed the grand feat of reappearing about three feet in the air. A moment of bewilderment, and then she was falling. Her landing hurt, but she jumped to her feet anyway, brushing off her injuries.

Again.

Luna filled her mind with images of the castle, trying to recall every detail, down to the paper-thin cracks in some of the stone blocks. She felt herself lift, fall away from the moon’s surface as magic enveloped her. And then she rematerialised, plummeting towards the surface and crashing into it.

Again.

Not even standing this time, Luna’s horn blazed once more. This time she trapped her leg underneath her when she fell, twisting it and crying out in pain.

The pain was good. It brought with it clarity; a return to her senses. Only ignorant or desperate ponies would attempt the same thing over and over, expecting things to change. Luna was not the first and couldn’t afford to be the second. She had to accept the truth that had been there since the beginning.

Something was repressing her magic – holding her back, keeping her contained.

Come on, Luna. You won’t, can’t, let it win. You can break through this.

Her memory flashed back to her arrival. To the bolt that she had sent forth, watching it shrink to a speck over the horizon. That had been after she had arrived, not before. She’d cast that on the moon. She could beat this. Drawing the magic through her once more, Luna prepared a similar bolt of energy. Again she released it, giving a shout of effort as the magic blasted free. Again she watched its light recede as it soared over the landscape, but this time Luna beamed in triumph.

Next she attempted to lift a moon rock, and succeeded in floating the pebble without a second thought. It spun effortlessly through the air, at least until she tried to send it to Equestria. It met with the same fate she had, falling back to the ground from only slightly higher than its original position.

No. She couldn’t have.

This time Luna tried to teleport it slightly to the right. A flash of magic, and the rock shifted exactly as she’d wanted it to.

There was only one answer. Only one thing that could be limiting her magic this way.

Binding magic.

Binding magic was tricky. For starters, there were two types: physical and anchored. Physical binding was simply that; the pony in question would be unable to leave the set area. It was quick and easy, but had gaping flaws, such as the ability to teleport outside the boundaries of the binding area. This had to be anchored then, which was far more involved.

Anchored binding required the caster to trap a tiny piece of their target inside whatever they were binding them to. The most common 'anchor' was a shard of the victim's soul, which sounded more difficult than it was. Binding a piece of soul was as simple as lifting a moon rock, especially for an alicorn as powerful as Celestia. The difficulty arose in setting the area. Typically, the spell would take hours to cast, in order to set exact specifications as to where the target was to be held. In the spur of the moment, Celestia needed to send her to a place where a wide and barely defined area would be of no consequence. And fortunately for her – though less fortunately for Luna – there happened to be a vast rock hundreds of miles above the atmosphere and hurtling through space that would do nicely. And Luna had put it there.

She pressed a hoof to her head, desperately trying to recall how to break anchored binding. The first solution would be to simply wait until it expired. But, with a pony as powerful as Celestia, a binding could easily last a thousand years. Hardly ideal.

What else? There was always the entire destruction of the moon itself. Also not good. Luna's own stubborn pride was too great to take that step. This was her moon. It was her last monument; she'd be damned if she was going to destroy it, even if that was exactly what Celestia was counting on to keep her there.

There was one final possibility. To locate the source of the magic, and to take it back. Find that sliver of her soul and return it to herself. That was by far the most desirable of the three, even with the obvious complications. The fragment was most likely embedded in the hardest to reach place; the very core of the moon. It would take her so long to dig it out that the binding would have already worn off by the time she was halfway there. And it was precisely what the spell would keep her from doing.

It didn't stop Luna from trying, and it's hard to blame her for it. But sure enough, when she attempted to shovel a hole from the ground, a mental wall slammed down over her thoughts and prevented her from even beginning the spell.

So that was that. There were no options. She was, to put it lightly, fucked.

Luna's Moon Diary
Entry 1

To anyone who may be reading this, I command you to stop immediately. This is the personal and private diary of Princess Luna, during her unfair and extremely cruel incarceration on and in the moon by the callous and evil 'Princess' Celestia. It is for no-one but Princess Luna herself, and anyone she may forthwith approve for future commemorations of her excellence in the face of such hardships. So stop now.

I mean it.

Really.

...

Now that anyone who has acquired this diary through less than legitimate means has gone, I can begin.

I, Princess Luna, am trapped on the moon. Celestia has placed a binding spell upon me, and I am anchored for the foreseeable future.

And I am not panicking.

The typical limiters associated with binding spells are in place; I am incapable of any magic or flight that is intended for me to escape. I cannot fly away. I cannot magic my way out. I can still utilise both as long as my intentions are not to escape, but seeing as how the anchor is a piece of my own soul, I cannot cheat it.

My solace is that my night sky is in constant display. The stars are especially beautiful 'tonight'.

I created this diary by transforming some moondust into a book and quill. I am fortunate that I can at least use that much power. However, I am unsure what I can fill this with. I can already see the days bleeding into each other, and wouldn't be surprised if this is my only entry. We will have to wait and see.

I'm not panicking.

***

She was.

***

Long curved shapes spiralled across the ground. Some curled up into the air while others coiled at Luna's hooves. The sculptures were made of solid moon rock; products of long nights with little else to do. Together they formed a twisted mass of stone, each strand as thick as Luna's leg and interweaving with the others to create something as imposing as it was delicate. It had taken her weeks.

With a single blast of her horn, Luna reduced it instantly to rubble.

Luna's Moon Diary
Entry 63

I destroyed my sculpture today. It wasn't as cathartic as I had hoped. Staring at it may have been nothing but a cruel reminder, but breaking it felt doubly so. How low I've fallen since my ill-fated rebellion.

I don't feel particularly well, and it's not just the sculpture causing it. It's deeper than that. Perhaps it's due to not eating. With my soul-anchor such things are not necessary to survive, but there's more to life than simply existing. I long for even the most meagre of servings; a lowly cress sandwich would be divine.

I never thought I could miss food this much.

***

Luna was back in Equestria. She was back in the castle, in the corridor leading to her sister's bedroom. Finally she would take her revenge.

The double doors seemed to fly towards her as she walked. With each step she took they grew closer by three. Her horn glowed, ready to strike as soon as she threw the unguarded entryway open.

Celestia was waiting for her. She lay reclined on her enormous four-poster bed, eyes beckoning her sister closer. Luna felt the magic drain from her horn at the sight. How could she have wanted to hurt someone so close to her? Someone so radiant, so... alluring.

Her sister smiled warmly. There was no resentment; she had forgiven Luna entirely. This was her welcome home. Celestia patted the bed, inviting Luna to join her, and how could the night princess have refused?

When she hopped onto the bed, Celestia held her tightly, an embrace that Luna had missed, even before all this had started. The physical contact she hadn't felt from her sibling ever since that brooding resentment had begun to build. And when the time came to break their embrace, Celestia took Luna's face in her hooves and kissed her. It was not a sisterly kiss.

There was far too much tongue for that.

It was the kiss of lovers who had spent too much time apart. A kiss that confirmed everything was going to be alright, and that promised before the evening was through they would both be lying thoroughly satisfied and breathing heavily next to each other.

When Celestia's hoof traced the base of her horn, Luna initially shied away, half in surprise, half in her continued hesitation as to whether they should be doing this. And yet she could barely stop herself. It occurred to her that neither of them had said a single word, but when Luna made to speak Celestia pressed a hoof to her mouth, shushing her. There was nothing that needed to be said; the answers lay in the other's touch, in her caress.

A sudden warmth surrounded Luna's horn as Celestia, emboldened by her sister's barely-restrained eagerness, curled her tongue around it. She ran up its length, sneaking into each sensitive groove, and Luna shuddered involuntarily.

Celestia didn't stop, instead taking the tip of Luna's horn into her mouth and swirling her tongue against it. Luna couldn't hold back the soft half-moan, half-gasp, that escaped between her parted lips. It wasn't just the feeling of Celestia’s soft tongue tracing around her (though she could attest that her sister was definitely more than capable), it was the pony involved.

The pony she'd lived her entire life with. In her long, long existence, Luna had never been as close to anyone as she was with Celestia. They'd fought, of course, but what sisters hadn't? It was even evident in their duel. Despite the risk that Celestia felt Luna posed to the entirety of Equestria, she had been incapable of bringing herself to actually harm her.

Luna had not shown the same restraint. Her spells were made to cause great injury, and even the quick, barely charged spell that did hit Celestia had been enough to send her spiralling to the ground. The binding had not been a decision Celestia would have taken lightly, but there had been no other way. And Luna regretted that. She regretted not giving her sister another option.

But that seemed unimportant now. Fading memories that were better off forgotten. Perhaps that was why Celestia had quieted her. Don't. Don't concern yourself with it. It's water under the bridge.

And so here they were, Celestia wrapped around Luna, showing her every bit of care and love that she'd done over the years. And quite a bit more besides. Luna felt building pressure in her horn as Celestia teased the magic out of it with long, thorough licks. Finally, as Celestia spun her tongue around the tip again, Luna could hold it no longer. Unshaped magic blasted from the tip into Celestia's waiting mouth; tingly and almost without substance.

Luna kissed her sister deeply in wordless thanks, and once again Celestia took control. She placed her hooves against the sides of Luna's head and gently guided her lower, down her body to her marehood.

It was the first time Luna had been this close to another mare's entrance. Her sister's musk filled her head, urging her forwards, and she pressed her muzzle against Celestia, tongue running over her folds, tasting her, feeling her sister’s warm wetness against her muzzle. Celestia sighed and let herself fall backwards as Luna – driven on by her reaction – pushed forwards, tongue running deeply against her.

Her movements were clumsy, inexperienced, but it was more than made up for by Luna’s pure enthusiasm. Nothing was left untouched, uncaressed, every movement exploring more of Celestia. Luna’s frantic breaths ran over Celestia’s skin, and each time it did so she would shudder, holding Luna’s head a little tighter against her.

Luna’s tongue circled her sister’s clit, toying with the sensitive nub, and Celestia gave a little squeak. Luna almost laughed. It was so unlike her, to see Celestia lose her air of grace and restraint. An embarrassed flush filled her sister’s cheeks, which Luna found almost unbearably cute. She didn’t have long to muse on it though; soon Celestia’s insistent hooves pressed Luna back between her folds.

Her sister’s marehood was hot, so hot, warmth surrounding Luna’s muzzle, the thick smell of her lust driving Luna to a frenzy, desperate to push Celestia further, to taste more of her. To feel her squirm at her touch. Tia’s hooves fell away from her head, waving weakly as she tried to grip something, anything, some support from Luna’s relentless assault. Her hind legs hooked over Luna’s shoulders, trying to draw her further in, though Luna was already as far as she could go, pressing as deeply as possible.

Her sister’s hips bucked against Luna’s mouth, the last fragile remains of Celestia’s composure falling apart under Luna’s ministrations, the sounds of her nickers and moans filling Luna’s ears as her excitement filled Luna’s mouth. Celestia thrust desperately against Luna’s muzzle, relying on that for stimulation just as much as the tongue that ceaselessly caressed her.

Her bucks grew quicker and shorter, the inevitable drawing near, but Luna responded by slowing her pace. Drawing out the pleasure, holding back the climax. Her sister mewled pitifully.

“Please…”

But Luna would have none of it, a devilish smile on her features. She let Celestia’s excitement recede, waited for her bucking to slow before redoubling her efforts, her sister’s needy cries spurring her on. Twice more she brought Celestia to the edge, twice more Tia pleaded with her but ultimately surrendered, allowing Luna to tease and toy with her. The fourth time, Luna instead increased her speed before pulling her muzzle away and circling Celestia’s clitoris one final time.

“Oh god…” Celestia whispered. It was all she could manage.

Even Tia seemed unprepared for the climax that rocked through her after being denied for so long, a wordless cry of pure exultation echoing through the chamber, shaking hind legs tensing around her sister as she came, wetness splashing against Luna’s face.

As she bucked and thrust her hips erratically, Luna responded with her own eagerness, keeping Celestia in that state of bliss for as long as she could, watching her writhe fitfully beneath her. But all good things must end, and soon enough Celestia took Luna’s head in her hooves and pulled her in for another kiss. The taste of her sister was still strong in Luna’s mouth, but Tia didn’t seem to care, if anything putting even more into it, leaving Luna almost unable to breathe in the passion of the moment.

When they broke apart, Celestia pressed Luna’s head to her chest before falling back, and Luna snuggled close. It was just like before, before everything had gone so wrong, and she let out a happy sigh into Celestia’s fur, listening to her rapidly beating heart, watching the rise and fall of her chest slow as her breathing returned to normal. Occasionally Tia would shiver slightly, the aftershocks of her climax running through her body.

They still didn’t say anything; there was nothing that needed to be said. Tomorrow would be the time for words, now was the time for silence, for enjoying each other’s presence and closeness.

The bed was a complete mess; pillows had been thrown across the room, in a couple of corners the sheet had been pulled free, and the covers were in a pile on the floor. The two sisters lay in the middle, surrounded by debris, each wrapped up in the other. The evening was warm, and at that moment, hearing the gentle chirp of crickets outside the windows, there was nowhere Luna would rather have been.

***

Awakenings from dreams like that are always unpleasant, and to find that soft bed and loving company replaced by hard rock and empty loneliness was especially so. Luna felt fresh anger rising through her. The forgiveness her dream-sister had shown her could clearly not be said for the one in real life.

Still, that had been an especially vivid dream, to say nothing of its content. She could almost still taste Celestia on her lips.

No, I'm not thinking about it. Forget it happened. Oh god forget that EVER happened.

And then, as she awakened fully...

Oh no. Oh no no no no, not now. Why now? Why here?

A warmth in her nethers, a deep and aching need that ran to her core. It had been hundreds of years since her last, but the feeling was unmistakable.

Luna was in heat.

Back in Equestria there were ponies who were trained to... alleviate it, but she wasn't in Canterlot. She wasn’t even on the same planet. She was in heat, and not only were there no stallions present, there never would be. Not for a thousand years, give or take. She was alone.

Luna's Diary
Entry 64

If this entry seeems a little haphazrd, then forgive me. I'm fnding it verry difficult to concentra. The worst thing possible has happnd.

Suddenly everything makes snse. Why I was feeling odd, why I had that dreamm. I've gone nto heat.

This is, without a dout, a bad thiing. I can barrly hold thequill straight, and this is only the strt.

Alicorns havee always had the wrst time whn it comes to estrus. We doo have the advantge of onlyhaving one evry few hunred years, but when we do? It's bad. I ned a stallion.

Ogod, when I think abot having one just rut me, bend me down and tke me so roghly that
[Illegible]
Do you seee what this iss doing to me? I cant blive I just wrote that. And yet it wold be fntastic, would clear my hed. I thnk my wrtttings actually gtting worse – let me caaalmdown.

Okay, it toook a while, but I should hav a little more control now. I'm sorry again, but the quilll is shaking sobadly.

I'm at the point where I considereed creating a 'replacement' out of the mooon rock. I probbly would if I thouht it wuld help. But it won't bcause it has to be mre than that. Somethng sentient.

Alive.

***

You can do this. It'll be difficult, yes, but you HAVE to do this. If you think you can't, you won't be able to.

Luna steadied herself, which was easier said than done. Her head was spinning, her loins pulling every bit of her attention they could. But somehow she managed to focus. Her horn lit up, and a large circle that she'd traced in front of her began to glow around the edges.

Contain it. Gently.

Shape it, slowly, bit by bit. Ignore that growing distraction, shut it out. Shut everything out. It was the only way she could keep any focus, to remember the snatches of information she had gleaned in her studies of magic. She shouldn’t know anything about this anyway; it was as taboo as magic could be. A reigning monarch couldn’t be caught studying it, and so Luna was trying to piece together hundreds of snippets from hundreds of books, hoping her skill was enough. That her sheer tenacity would see her through, and avoiding thinking about what could happen if she got it wrong.

Concentrate. Remember.

Magic began to eke out of Luna’s horn, filling the groove of the circle in front of her with a cold, blue light. Her own body seemed desperate to betray her, insatiable desire filling her, doing its best to draw her away from the task at hoof. Exhaustion racked through Luna’s body, her legs trembling and threatening to give out at any moment. Her face was locked in a rictus of concentration; there was no room for mistakes, she had to keep going. Even with the rising waves of lust that crashed through her.

The circle in front of her began to spin. Luna had no idea if that was promising or horrifying, but spin it did, the glow from the edges becoming so bright it was nearly impossible to see into the centre, where the rock was slowly reforming itself.

With a final explosion of energy Luna released the last of her magic and was hurled backwards by its force. Stabilising with her wings, she recovered quickly, staring at the smoking crater she had made. The sides were perfectly smooth, leaving a deep, bowl-shaped depression in the moon's surface.

And in the centre, in the clouds of dust that were beginning to dissipate, something stirred.
