Twilight Sparkle Gets Sent to the Principal's Office

Once inside the womb, Twilight found herself tight, cramped, and with very little room to move. Her mind worked fast to piece together what she thought was the truth: this was a test to prove herself. She first attempted to push her way back outside of the womb but found it was too tight for her to force her way out. Her second attempt was to kick and squirm about to try and bring discomfort to Celestia, but she quickly realized it was just a waste of her energy. Finally she tried her third attempt. She lit up her horn to try and teleport out. Unfortunately, she felt the same magic drain she had earlier while wedged in Celestia’s tight pussy with no apparent effect. She wasn’t outside the womb, the spell hadn’t cast as far as she could tell, but the magic had been drained. When she felt something inside the womb along with her, she lit up her horn for a weak illumination spell, happy to see that working at least.

What she wasn’t happy to see was what was shown with her light: some kind of tube sliding along her belly. She let out a sharp yipe when it felt like it had bit onto her, the sharp, though brief, pain causing her to thrash about.

Twilight, in her panic when the umbilical cord attached to her with that sharp sting, attempted a second teleportation spell, this time feeling the magic drained away from her and out, not by her horn but through the cord attached to her. She felt a hoof rubbing against the bulge she made and just barely made out the words of Celestia.

“Casting spells will only serve to speed the process further.”

Twilight was confused about what Celestia meant by process. She tried to concentrate and cast a more powerful teleportation spell but she felt the same drain in magic but with no results. She also found a strange sensation. Despite expending her magic, she still felt like she had a full charge of mana. And she also came to the realization that the womb she was in seemed less cramped. Calming herself she finally lay still and steadied herself, listening and waiting. Now she could detect in herself a magical leak. Her magic wasn’t being focused on her horn but at her belly. Right where the umbilical cord was attached. Twilight also found her surroundings not quite as tight as before. Was she shrinking?

“P-Princess!? What’s happening to me? Is this a test?” Twilight asked hastily, bring a hoof up to her mouth at the sound she made. It was the same pitch now as when… as when she was… “I’m getting younger? But how? Why?”

“If I forgave you for your mistake once again, you’ll only go forward continuing to make the same mistakes. Even if I were to send you back to Magic Kindergarten, I’m afraid nothing could be done to guarantee the same mistakes not being made again.”

As Celestia spoke, Twilight found herself getting younger, as years were taken from her in a matter of seconds..

“My explanation to you really means nothing, though. There’s nothing you can do to stop me. Your memories I’m leaving alone but it will eventually not matter,” she said, rubbing a hoof on her belly. She estimated Twilight to have lost a good deal of age by that point, perhaps around 10 to 15 years. “Every friendship you’ve made, everypony that knows you is forgetting about you.” Celestia paused to glance at her shrinking belly, feeling the magic drained away from Twilight.

“Oh don’t worry,” she continued, no longer expecting a response from a pony too young to even speak now. “I will still remember you, at least for some time. How you failed me and what I was forced to do.” Her belly looked flat but she could still feel the magic being drained. Embryo became a mass of cells, cells became a single cell, an egg impregnated by a sperm. As her magic began to wind down the fertilized egg split one last time. Inside her womb was a single sperm and an egg. She used her magic to keep the sperm away from the egg long enough until it expended all of its’ energy and went still.

“I’ll eventually forget about you just like everypony else, but for now I’ll use your failures to improve my teaching for my next faithful student.
