Chapter the First

Author's Note

This is just a little prologue to the actually good stuff. Way darker in tone than what I have in mind for everything that will follow it. I wanted to give darn a good reason for Luna to end up sleeping in her sister's bed. Plus its helpful to have a sort of warm-up after not writing anything in a long while. Hope it makes for a compelling, if extremely short, read.

Chapter the First

It is just after midnight on a cool summer evening. The moon hangs full and proud above a city of dreaming unicorns. Ill gotten flame bathes the streets below, making cobblestone dance spectacularly as if bewitched. At the halfway point between heaven and earth, the Princess of the Night stirs from her trance.

Luna had found herself within the dream of an orphan colt, where she did battle with manifestations of trauma she could not hope to soothe. The young urchin's indescribable sorrow had affected her deeply, and her will to fight faltered. She could do nothing more than flee, and vow to rescue the poor foal in the waking world.

She now stands, crestfallen, atop her spire. Though certain she will make good on her promise, she nonetheless feels as though she has failed her subjects. Ashamed though she is, Luna recognizes that she is in no state to aid ponies in their dreams and resolves to take the rest of the night for herself. She hopes the ponies of Equestria will once again pardon her absence from their dreams as she makes her way to bed.

Luna spends an agonizing hour chasing sleep in the dark of her bedchamber. Eventually, she finds it. Rest, however, still eludes her. She dreams of Canterlot arranged as a labyrinth, and of herself arranged as a great heroine. She fearlessly navigates its shifting corridors and presses on towards its heart. Though upon arriving at the maze's center, she finds no minotaur to fell. Her Asterion is a child, alone and sobbing. He turns to face his savior, and her noble visage dams his eyes. He beams a gap-toothed smile at her which reveals discolored gums. Luna reaches out to touch the colt's face, but in that instant his body melts like wax, leaving behind that gap-tooth smile, disembodied. His teeth, too, begin to melt and soon all that remains is the gap, pitch black and screaming. Its nothingness swallows Luna whole.

A moment later, darkness constricts the princess. She is trapped, as though bound in a sack sunken deep below the water. The damp walls of her prison tighten around her rhythmically, as warm liquid begins to pool at her hooves. Slowly the warmth climbs up her body until it grazes her chin. She can hardly breathe. Her pupils widen with terror. There is only blackness here to fill them. Finally, the liquid submerges her completely, and begins to fill her lungs. It tastes sour. It stings as it invades the cavities of her body. Just as Luna realizes that she is going to die here, choked by hot sloshing void, she wakes up.

Chapter the Second

Luna has woken up, face down, in a pool of her own urine. As she pushes herself up, drops of pee are shaken loose from her damp neck. It has been years, actual millennia, since she last embarrassed herself in this manner. The feeling, however, remains familiar as if she was still the same bed wetting filly she had been all those lifetimes ago. Her bedding, it would seem, is near water proof. This proves to be a mixed blessing. Without permeable fabric to bleed into, the piss has nowhere to go besides her own coat. The princess is completely drenched in her own mess, a puddle of un-absorbed pee surrounding her. She is torn between profound embarrassment and a strange desire to remain in its warmth. After such a harrowing dream, it feels almost comforting, like a liquid hug.

Gradually, the warmth fades, and a cold reality sets in. Luna realizes she will have to inform the guards. The thought alone sends her heart racing. She can't claim to have ever been well respected, beyond the pleasantries her royalty demanded from those in her presence, but this would ruin her. Once the rumor mill turned, the whole world would grow cruel around her. Every eye in Equestria would cast a harsh leer, every whisper another voice in the chorus of mockery she must endure. She'd be forced each day to confront the plain truth about herself: she was an embarrassment to her people and a sorry excuse for a princess, serving them best when she was hidden from sight.

All of this worrying was absurd though. She can trust her guardsmen not to let slip her horrible secret. They would mock her within the walls of the castle, sure, but they would never seek to shame their princess in the eyes of her public. She calls two in from the hall, and begins to draw herself a bath as they set about the task of cleaning up her royal mess. Their stern expressions do little to assuage her fear, but at the very least she can say she isn't being openly mocked. She can live with the quiet, implied, sort of judgement. She always has.

Her bath is now ready for her. She steps in and a new, clean, warmth soaks her fur. Just for a moment, she almost feels at peace. This does not last. An acrid scent finds its way to her nostril and she realizes that, scrub as she might, the smell of urine will not leave her. If she can not perish the reek of her shame, then a paltry attempt to mask it must suffice. As her bath drains, Luna towels off in front of her vanity and emits a long sigh. Without a dry bed of her own to sleep in, there is only one path forward to reach a good night's rest.

Remaining in front of her vanity, Luna takes a moment to contemplate the many bruises her already weathered ego has endured tonight, and the further battery it will be made to endure. To ask her older sister to share her bed would be humiliating under any pretense, but especially after wetting herself. She felt the phantom pain of an imagined scolding, Celestia's sharp tongue piercing sternum and sinew to rasp against her frail heart.

Luna reasons that if she must meet her sister tonight as a scared filly in spirit, she may benefit from putting on an affected sort of neoteny. She pouts at herself in the mirror, trying her best to look every bit as vulnerable as she feels in this moment. She would rather be pitied by her sister than the subject of open contempt, she thinks. Shooting one last miserable look, she steels herself and sets off for her sisters chambers, the scent of her own pee in dogged pursuit.

Chapter the Third

Something has gone wrong. We don't seem to have an archived copy of that chapter.

Chapter the Epilogue

After a morning spent dealing with the mess Luna made of both of their beds, the sisters finally find time to sit down and enjoy a breakfast they had made together. Celestia's pancakes, so divinely fluffy that one could be forgiven for mistaking them for angel food, were complimented perfectly by a pineapple syrup of Luna's own design. Also included in the spread were spinach omelettes, fresh squeezed orange juice, and that most taboo indulgence of the Equestrian nobility: bacon.

The sisters enjoy their meal in silence, quietly contemplating the night they had just shared. Luna's disposition begins to sour, though, as her mind turns to that poor colt. What was his name? Where did he live? Could she do anything to help him now? Luna is unable to answer these questions for herself and seeks comfort in her sister once more.

"Celestia, I have need to speak with you once more about last night. The foal I met in a dream, I think I would like to find him and do for him in the waking world what I failed to in the night. If it pleases you, dear sister, I would like to take him in as our son."

Celestia smiles brightly, overjoyed by the love and charity in her sister's heart. "That is a wonderful idea. I'll have the guards prepare a room in anticipation of his arrival, though I am afraid it falls upon you to locate him," Celestia says. "I have a long day of playing host to diplomats before me. Do you have any idea where this young orphan might be?"

"I should think," answers Luna, "he is here in Canterlot somewhere. The shape of his dream was eerily familiar, bearing resemblance to streets I have walked before, yet twisted and ominous."

"Very well then, good luck in your search, sweetheart." Luna blushes as she gets up to leave. "and Luna," Celestia calls as her sister walks away, "please visit me in my dreams again sometime."

Author's Note

That's all for now!! I have a follow-up planned to resolve Luna's search for colt she hopes to take in off the streets, as well as further explore her budding romance with her sister, but tacking any of that on to this epilogue was feeling extraneous to the story as it exists so far so I decided to leave off on the note of the two sisters enjoying a morning together before returning to their individual lives for the day. Hope you enjoyed reading my first serious attempt at writing weird kink porn! ^u^
