Celestia elegantly grunted, as the commotion in her barrel grew rather intense, halting the princess’s graceful gait as she took a leisurely stroll across one of the marble-clad galleries of the royal palace. The long-stained glass window-lined corridor the ideal place to mull, as digestion took its course and today was no different as a familiar tail hung from the solar snatch twitching weakly. The nerdy squeals emanating from within Celestia’s taut belly loud and persistent, as the wriggling of her cunt consumed student had continued unabated the moment the puffy pussy had parted to shepherd the surprised unicorn to her princesses’ foal foundry.

The hum of magic joining the struggling sounds of distress, as a light purple hue began to emanate through Celestia’s side as Twilight tried a new strategy to escape the musky confides she found herself bundled in. The twinkling sensation of magic trying to manifest something tickling Celestia’s entrails, causing her to smirk at the pointless attempt that did little more than provide another exotic stimulation to the tactile commotions of her cooch captive. Twilight putting up a rather poor showing as the mare had not yet been able to invert herself, the slick womb walls offering no grip as she just squirmed like a worm stuck in treacle. This lack of meaningful motion leaving Celestia with the quirk of having two tails trailing behind her, as Twilight had not managed to pull in her straight brush-like dock accessory, not that her teacher minded as the course material was caressing her clitoris pleasantly with each step. The stimulation keeping the loins in a state of constant attention leaving Celestia to drizzle some of the contents of her honeypot in slick streaks down the normally well-groomed bundle of hair.

The sparkle of magic growing ever more intense, as Twilight attempted to blink out of her birth-related binding as the cervix was pinching her dock holding her contained in the swampy space. The humid interior tart and constricting as the uterus tightened to hold the misbehaving pupil primed for whatever the alicorns innards intended to do with her flailing form. But this was all for naught as it simply made Celestia’s cheeks flush red as she scrunched her svelte face to suppress a moan, the mature mare not having experienced this much attention in over a century and it was doing a number on her carnal needs. Biting her bottom lip and giving a calming exhale, Celestia turned her head, a content smile on her muzzle, as she wanted to see her middle dance as her letterbox lunch fought with an A for effort. Her time-worn magenta eyes seeing the aura of her student putting her all into a spell that would sizzle out like a match in the rain like all her miscasts since she had become lost in the guts of her superior. Twilight was a gifted mare, but she could no more escape her destiny than any other pony and the mewling librarian would endure the same fate that Celestia had over an epoch prior.

Savouring the quivering of her quim and the trembling of her meaty mons, Celestia breathed in her conquest of her shaking student, who seemed to be being smothered by the compressing one-sided coitus as the womb worked her over with its steel gripped clenches. The magic doing nothing but adding a slight smell of melting metal to the room, as Celestia’s magically charge bones absorbed any meaningful projection of the smaller mares will, leaving her magical staff little more than an impotent glowstick adding a light show to the after-meal entertainment that was her weak wristed resistance. The confused sounds of an unexpected betrayal hitting Celestia’s heartstrings as she meant the mare within her no harm, though the intimate ingestion had been enough to give the unicorn second thoughts and when she had been into her hips she had changed her mind and gone from willing passenger to hollering hostage in an instant.

This left a cloud of regret to hang in Celestia’s mind, but it was easily quashed by the lustful lullaby that was singing its sweet caress throughout her engorged marehood, as the divine bulge finally began to tucker out as Twilight capitulated to the whims of her better. The naïve mare would soon forgive her tutor, and these begging yelps for release would soon dim as the unicorn realised her role and embraced the future with open arms. Celestia thinking it was wise to remind her student that she meant no malicious intent and placing her hoof gently on the bulge that housed Twilight’s bright brain she began to let her voice flow like a river of milk and honey.

“Shush, just relax Twilight, all will be revealed soon my most faithful student,” comforted Celestia, the mare not sure if her words reaching through the body cavity to her snared snatch snack's sexual secretion flooded ears. The tender touch of a gold-clad frog seemed to work better, as the heavenly hoof rubbed Twilight’s cheek affectionately like a mother would her foal, and after a few strokes of the lithe wrist, the unicorn’s horn dimmed as she relaxed into a slack fetal fold. The bulge dull, but clear as the mare within was easily manipulated into a shape that would allow her to sit comfortably during the strenuous spell that was soon going to course over her body in electric waves.

“That’s a good girl, sleep, it will be over soon…” whispered Celestia, as she felt Twilight go loose as she embraced Luna’s gift, the mare giving herself as she was finally ready for her metamorphosis to the monarchs equal. Celestia was not sure if it was willingly, or the stale atmosphere and sex hormones getting to the younger equines mind stilling the bucking of that paunchy plot, but soon it would be time to cast the spell that would allow the unicorn to be reborn an alicorn. The process not the most orthodox, but in order for the rebirth to occur the mare would have to regress to the point just before her egg was fertilized and from there be conceived and reformed with the elements of all three pony tribes in a crucible of powerful enchantments.

Of course, this situation was not the least bit orthodox and was a dangerous endeavour that skirted the edge of hedonistic hubris, as it was liable to go wrong as the sharing of such magic could end fatally for those of weak constitution. In her years Celestia had only met 4 ponies including herself who could qualify for such a risk to be taken, the first her dear sister, the second her pink niece and the final was the mare within her now who would soon be regressing to the point of inception to start again as a living embodiment of a school of magic.

Celestia’s only concern was that her years might be getting to her and she might have forgotten a step in the correct nuances of this forbidden magic, as the possibility for a melty mistake to be made was always present. The alicorn would surely find out the true extent of her magical capacity in a few hours when she either exuded an ascended alicorn in a wash of amniotic fluid, or she deposited a greasy purple pony pellet as Twilight’s frame failed and she was metabolized in a fizzling frenzy of energy. Her flesh reduced to little more than calories expended in the surge of magic, leaving her oily marecum soaked fur as the only testament to her ever existing.

Only time would tell but Celestia was confident that Twilight would not melt under the pressure and would be at her side soon. This created a strange situation though as it would be some time until Twilight was ready to crown, which to Celestia’s delight gave the restrained regent plenty of time to burn off some of this steam her student had stoked with a hot bath. The aftershocks of Twilight’s stubborn opposition to being reduced to an ovum leaving the normally parched pussy damper then it had been in decades, and it would be prudent to make the most of the sensual situation……..

Today we have something rather special for my seemingly weekly collab with Crazy water ( https://derpibooru.org/tags/artist-colon-crazy+water ).

Introducing "Insert pony here," the current only tier in Crazy water's patreon, where patreons are given the chance to vote on a pred, and then get an edit of said image with the poor pony of their choice tucked up tight in some sodden sack.

This time the pred is the always classy Princess Celestia, as lets be honest who doesn't like that plump plot. If you would be interested in gaining access to having a say in who makes lewd lumps in a myriad of midsections, pop over to my boi's patreon ( https://www.patreon.com/crazy_water ).

Oc's, cannon ponies, all are options, as it's up to the discretion of each individual patron to pick who is reduced to a bouncing bump each month. perhaps celly is punishing an upstart Starlight, or maybe its Luna squirreled away to sleep. if cannon is not your cup of tea, well perhaps your personal oc is getting more then a little intimate with royalty, the choice is yours.
