Trapped In The Moon

☀

Once Celestia was able to make out the approaching figure was her sister, she felt a swell of relief flood through her. Between her and Luna, it wouldn't be too hard to get in contact with Discord and make him fix this. Strangely enough, a part of her wondered if it really was Discord's fault that this happened; magical anomalies were not uncommon in Equestria, but for something as extreme as this... it seemed too much like a prank to just be a coincidence.

Her musings, however, ended as soon as the massive form of Luna dwarfed her vision. It was quite a marvelous sight, really, to see her sister tower over her like a mountain. At her size It almost looked like her mane could actually be the night sky. Celestia waved to her younger sister, only for confusion, then fear to replace the wonder.

Luna was turning around. For some reason she couldn't see Celestia, and as the view of Luna's forelegs, barrel, head, and mane were replaced by her hindlegs, flank, and tail, it was all to apparent to Celestia what was about to happen. With a great flap of her wings, the Alicorn launched herself into the air in hopes that she could escape the impact zone before it was too late--what she didn't count on was how fatigued her body would feel. The take of was slow, lethargic, and it brought her to the point of near exhaustion just to get off the seat.

She was smashed into the cushion of her own throne as Luna's rear slammed into her like a meteor. Now, while being trapped beneath Luna's flanks wasn't even last on the list of things Celestia ever wanted to do, if that was all that happened than maybe Celestia wouldn't be as horrified as she was now.

She was not trapped beneath Luna's flanks, but between them. She could feel the hot ring of muscle that made up the Lunar Princess's plot pressed against her back, and with each breath her lungs were filled with a mix of the spicy, pleasing scent of lilies, roses, and jasmine mixed with a hint of cinnamon, clove, and anise combined with the pungent, earthy fumes pouring from the musky orifice above her.

It may surprise some to hear that Celestia, while both afraid and embarrassed to find herself under her sister's posterior, did not truly mind the smell. It would be a lie to say she liked it, and it would be even more wrong to say that she wasn't disgusted at the thought of breathing it in, but Luna was at least very thorough while bathing herself and her soap--which was meant to smell like moonflowers--was at least strong enough to at least diminish the natural scent of her tailhole.

Still, that was hardly a comfort to the Sun Princess as she tried to squirm her way free--and act which, unfortunately but not surprisingly, only managed to make things worse. With a startled gasp of breath Celestia's body was pressed further into Luna's hole as the massive ponut smashed, rolled, and crushed her body against its twitching flesh and even--to her horror--partway inside it.

She wanted to struggle, wanted to fight hoof and horn to escape the heated prison in which she found herself gripped by, but even her body was wedged partway within Luna's hind-quarters, and the air lost its floral scent to the more fetid smells of Luna's depths, Celestia knew that trying to escape further would only end in greater misfortune.

As an Alicorn, Celestia could afford to be more patient than a normal pony would in this situation. She remained still as she could, even as the muscle continued to clench and push against her in some vain attempt to stifle the irritation she caused. Even as the oxygen in her lungs were squeezed out, and faint traces of methane began to take its place within her, this wasn't anything she couldn't handle physically.

Mentally, though... Celestia wasn't sure if she'd ever be able to look at Luna the same way after this.

After a few seconds of being treated like an anal chew toy, Celestia's patience payed off she felt her the G-Forces of Luna standing up slam into her body. Greedily, the tiny pony sucked in the fresh air as soon as she was able; given where she was and how deep she was pushed inside Luna, it was only natural that the air still bored the scent of the Alicorn's hind-quarters, but the scent was bearable so long as the air wasn't produced in Luna's colon.

Celestia's struggles to escape resumed immediately; she was sluggish, yes, but even though her voice was gone and her magic was currently sapped, her wings could still hold her aloft if she could just use them. Perhaps if the circumstances weren't so dire, the Solar Princess would have noticed how mesmerizing the sight before her was--strange thing to say, I know, but just try to picture it; just ahead of Celestia, constantly rippling and flowing through the air as if caught in the breeze , was a perfect image of an entire galaxy born within Luna's tail.

Where Celestia's mane and tail were an aurora of light and color, Luna's was a nebula; stars both dim and bright twinkled in the ethereal mass of blues and purples--moreover, whenever the light managed to strike her hair just right, the colors would change or darken, allowing yellows and black into the spectrum while simultaneously accentuating the natural, ever present hues.

Strands of faint, wispy blue hair writhed and swayed in translucent beauty, occasionally giving the impression of shooting stars being vanishing back into her mane or tail. As hard as one might try, to convey the beauty of Luna's mane and tail they would have to describe the beauty of the night sky itself--something I fear is beyond my own meager abilities.

Celestia had almost freed herself from her unwitting captive, and perhaps as she flew away she may have been able to marvel at the beauty her sister held, but instead of freedom a blue light matching the color and feel of Luna's magic enveloped her and the sphincter, and instead of flying out she felt her body being shoved deeper in, the feeling that somepony was scratching her entire body following her as she was forced deeper and deeper.

No more was the air safe the breath, nor did she smell the scent of moonflowers mingling with the musk--instead, with each panicked breath Celestia took, her nostrils and lungs were assaulted with the putrid scent of pony waste. She began to feel a slimy substance she really didn't want to think of cling to her pristine white fur, as the heat radiating from Luna's insides rolled over her as if she stepped into a sauna.

The pushing stopped before Celestia breached the other side of her sister's sphincter, even as the magic continued for a few seconds longer. Just as quickly as it happened, the spell ended, and with a silent scream that could only be heard in her own mind, Celestia was enveloped by the filthy walls of Luna's inner ponut and held firmly in place as the mare outside resumed her night...
