Luna's Nightmare

Had it always been like this? Luna couldn’t say anymore. It had been so long here in the moonlit void that she honestly had no idea about whether there had even been a before or if that was just her imagination.

All she had was her own thoughts, and so she had done her best to preserve her sanity. She spent her time building up imaginary cities and lands full of ponies of all shapes and kinds, and even beyond that, other races of creatures: griffons, dragons, bugbears, diamond dogs, minotaurs, all that and more. And they would mix and fight and love each other, and it was all wonderful.

But her imagination was only so formidable, and over time it all became the same. The stories she told herself turned trite, and everything returned to the starry void as a formless slush. No matter how far she wandered nor how high she flew, it was all just one unending emptiness, and no one mare could fill it no matter how hard she tried to dream up a better world.

So it was until one fateful night (for it was only ever night, with the ever-present moon hanging over her) that she saw something in the waters she normally waded through. There, deep in the murk, was a light from something else than the moon. A bright orange glow. She wasn’t a merpony, but she could still swim, so she dived down desperately to reach the source of the illumination.

Luna kicked her legs harder. She had to reach it. It was new. It was something she hadn’t seen before. She had to know what it was. After swimming for what felt like forever, she got close enough that she could see it as more than a faint glowing dot.

It was a glass orb floating gently in the eternal sea. And inside it was a world, or rather, a dream? Yes, a dream, that felt right. She swum closer until her face was practically rubbing the transparent surface. She couldn’t look away even if she wanted to, so captivating was the dream inside. There she saw a white mare with pastel-colored hair. Sister.

Her sister. This was her sister’s dream. She had forgotten about her sister. But now she remembered. Or was that just a dream she had and this was some sort of manifestation? Either way it was new and exciting, and so she watched as her sister fought a dragon. She was so radiant, shining with the sun, and that light escaped the dream to pollute the void, brightening it too just a bit. Luna watched as her sister defeated the dragon and afterwards flew to a castle whereupon the white mare resided upon a throne. There were two thrones, but nopony sat in the other one.

“Sister,” she tried to talk to the dream, but her words didn’t have any effect. It was just her talking to herself. “Can you hear me?” No response other than the continued lonely look on her sister’s face.

“Gift.” She heard herself say, but her mouth didn’t move. “Yours.” This was hers? This dream? She looked at the orb again and placed her hoof on it. ‘Mine’ she thought, and imagined herself on that empty throne. Sure enough, a representation of her appeared on it. Her sister started in shock before immediately leaning over and hugging her, crying her name over and over again, asking if she was real, saying that this must be a dream.

The orb disappeared.

“No! Don’t go!” She tried to grab it back, but it was gone and her hoofs only passed through the newly returned darkness.

“Wake.” Her voice said again without her mouth moving. Had she woken up? “Sister. Wake.” Or had her sister awakened. This dream, it wasn’t hers, but her sisters’. But it also was hers? “Every. Dream. Yours.” Dreams were her demesne. She could see them, change them, own them. She remembered. Or she learned? Was this new knowledge or old memories resurfaced, like bubbles form the everdark ocean?

In any case, the dream was gone for now. She swam back up and out of the sea to float once more in the air. Back to the nothing that was her accustomed night. She waited, and waited, and then the dream showed up again.

“Dream.” Her voice said, alerting her to its presence even before she could see its light in the black depths. She dove down and swam to it once more. “Ours. Shape. Change.” Yes, she’d change it, make it better. She looked on as her sister was teaching a student. Some gray skinned unicorn with a starry cape. Her sister was reading out of a book and occasionally demonstrating some spells to the unicorn who was paying rapt attention and sometimes even managing to reproduce them.

Luna felt a flicker of jealously stir. It should be her and not some random colt that her sister dreamed about. She reached out a hoof to the orb and imposed her will. The image in the orb changed, and now it was her sister who was being taught by Luna.

She was teaching her sister about darkness spells and how to conjure them even in the brightest day. And how to move the moon. And how to instill nightmares. But her sister couldn’t do any of that, no matter how hard she tried. Her nature was just too inimical to such. But that was okay. Luna could handle it.

The dream disappeared again. But this didn’t bother Luna nearly as much as last time. She just waited on the spot, and soon enough (for everything not measured in eons was soon), the dream reappeared.

“Connection. Stronger.” Her voice said. “Prison. Weaker.” She spoke to herself more often now. And each time the dream re-appeared and she applied her will to it, her voice became clearer, more defined. Like it had once been lost, diminished, but was returning.

And she continued modifying her sister’s dreams to always be about Luna in some way or another. It wasn’t always front and center, but she was ever-present. She had to be. It was a way of escaping the void in some minuscule manner. It was being with her dear sister. She loved her. Loved the memory of her. Loved the discovery of her sister’s innermost wants and thoughts, and changing them. “Love. Change.”

Some nights even, she indulged in some very dark deeds. “Desire. Us.” Her sister should want her as Luna wanted her sister. She made it so Celestia’s dream-self danced for her. And another night she made it so she sung love ballads. Another night was spent with the two simply hugging each other as tight as possible, so much so that they struggled to breath for moments.

And another night, why, she made it so her sister stripped out of her regal attire. And then her small-clothes. Until she was as naked as the day she emerged from chaos as an avatar of order. Luna made Celestia say, “Luna, I love you. I need you.” Like a doll, a lovely, beautiful doll.

“I love you too, sister. Celestia.”

“Love.” Her voice added. “All. Love.” It was only after many such nights that Luna even noticed that her voice wasn’t coming from her mouth at all. Instead it was from the moon above that it sounded. Like there was another her residing there, mimicking her thoughts. “Us. One.” But that wasn’t a problem, because she was a goddess, and a goddess could have multiple bodies, multiple forms joined together to be greater than the parts. Her moon voice agreed, for Luna could feel its thoughts even without it speaking. For it was her, and she was it.

That realization spurred another. This too was a dream. Or a nightmare? Yes, a nightmare sounded right. She was asleep. Had been, for a very long time, lost in a daze. But now she was awake, awake in the nightmare. Why wasn’t she awake outside of the nightmare?

“Prison. Escape.” She was trapped here. “Sister.” By her sister. Why would her dear sister do that to her? “Bad. Wrong.” Celestia had done something very naughty, but that was okay, Luna would forgive her after she had been punished. “Punish.” In the dream, in the nightmare at first, and then in the waking world when Luna finally departed this realm.

Luna listened to the moon voice as it told her what would be. It was odd, listening to one’s own thoughts from another source than one’s own brain, but that was the logic of the nightmare, and in a way it made a sort of twisted sense. For was there no greater suffering than the loss of self, the loss of one’s own identity suborned to another? And wasn’t it her justice to inflict that on others? Every single last pony would feel that same despair. That same love.

“Sister.” “Sister, fuck me.” She changed it so the dream had the two of them on her sister’s royal bed. It was a huge, scarlet affair, with drapes and everything. Plush pillows upon which her sister’s head resided and her naked form spread out across its length. And on top was Luna with a huge cock. In the dream, in the nightmare, everything was possible.

“Oh, Luna. Fuck me, please. I’ve wanted you for so long,” the doll said. The Luna doll did just that. She plunged her cock inside her sister’s cunt, and the real Luna watched on from outside. It was stimulating, enough so that she started masturbating herself while watching the performance. Was it like this too for her sister in the waking world. Did she finger herself to vague recollections of their incestuous dream pairing?

“Yes.” Oh, so the dreams did effect her sister. “Change. Become.” They were molding her sister. Slowly, gradually, completely.

Her dream-within-a-dream self continued pounding Celestia’s pussy. Luna closed her eyes. She could imagine herself doing so, feeling that tight confine envelop her imaginary cock. How good that would feel, dominating her sister like that in reality, how good it would feel to make her sister her cumslut. “Deserved.” It was only what she deserved.
