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.

“Now now, Twilight, please calm down. You are safe, you won’t be harmed beyond the small sting on my umbilical cord attaching to you.”

Twilight, in her panic, 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.

“There’s no need to panic. Casting spells, however, 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?”

“I have decided that I will give you a do over. Since you’ve made so many mistakes in the past and haven’t seemed to learn from them, instead of expelling you from my mentorship I’ll simply regress you back to a foal and send you back to Magic Kindergarten. Most of your knowledge will disappear in the process, but I’m making sure that the failures you have committed and the reason for you going back remain intact so this doesn’t happen again.”

Twilight had many questions. How was Celestia doing this? Was it going to hurt? Was this going to mean that Celestia was her mother now? And what of her friends? Her… friends? As Twilight continued to get younger and younger in Celestia’s womb, knowledge of the friends she had made faded away. A pinkish purple unicorn, a blue unicorn that she thought might have been a rival, faces without names. And even those faces faded away. She was soon left with just memories of her closest friends and her family.

Minute details on what her and her friends had done as the Elements of Harmony disappeared. All that remained was a vague sense of the events that happened and how she had screwed them up. She grew smaller, younger, her mind losing more memories. One by one she forgot about her closest friends, a pink one, a yellow one, a white one, a blue one, an orange one, another pink… no, that was the same pink one. More faces without names and eventually, not even faces. Then even her family memories. She had a mother and a father and a brother, but their names escaped her. By then she was nearing less than three years old. The years drained from her until finally, everypony she had known, the spells she had learned, all of her memories save for her mistakes, gone. Finally, the regression stopped, leaving Twilight at about half of Celestia’s gestation period. It would take a few months and careful mental manipulation as Twilight grew, but she would someday be ready to be born to attempt her learning yet again.

Celestia moved a hoof to rub at her still obviously pregnant but not quite as round belly and cooed softly. “My little pony, I hope you will not make the same mistakes growing up as you did the first time.” She paused and continued to rub on her belly. “That is, if I decide to keep you to term.”
