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.

“I’m afraid that all spells you attempt to cast get redirected into me. An easy and effective way to recharge my own magic without needing rest. But that’s really not something to concern yourself with right now. Doesn’t it feel warmer inside me than it should?” Celestia asked, hoof trailing on her squirming belly.

Twilight froze and finally realized that it was much warmer than a pony womb should be. But her mind tried to rationalize it by comparing the increased temperature to the fact that Celestia was tied to the sun. A reasonable assumption but it seemed to be getting hotter by the second. She was sweating profusely. She lit her horn for an illumination spell and wiped her brow. It was so hot she could swear she was melting. She glanced at her hoof and gasped. The sweat on her body wasn’t clear like sweat, but more purple in color. As it dripped off, it began to pool around her trapped body. She began to push and fight again but found her hooves and legs bending in ways they shouldn’t. She had no purchase and no rigidity to push any more.

“H-how? I’m… I’m melting?”

“Painless, right? Just a few hours inside and you’ll get fully melted. Well, it’s not exactly melting, I’ve cast a spell on my womb. Anything inside is slowly transformed from solid into liquid. But in this case the liquid is my own mare juices. And do you know what I’m going to do once you’re transformed?”

Twilight shook her head as she felt more of herself painlessly drip into the rising puddle around her.

“I… no? Why? What are you doing? Is this some kind of test?” asked Twilight in what sounded like hurried desperation. “Please, let me out! I’m getting smaller as time passes and the stuff I’m turning into is rising higher!

Celestia only shook her head in response. “Twilight, this is no test. This is your punishment for failing so many times. I’ve decided that, once you’ve finished your detention in my womb, you are to be expelled!”

Twilight drooped her ears and a horrified expression crossed her face. “Ex-Expelled? But, if I’m expelled, I’ll never get into any other magic school! Who’ll take a unicorn that was expelled from Celestia’s School for Gifted Unicorns?”

Celestia gave a slight chuckle. “As always, the faithful student makes a grave error. Getting into another school will not be a concern of yours. I literally mean expelled. As in, you’re going to be my release after clopping.”

It felt as if the heat was turned up yet again, the illumination spell fading out when her horn dripped off into the rising puddle. She could still move, albeit her movements became limited. Twilight continued to grow ever smaller, her sharp defined outline now looking more smooth and round. She attempted to speak, but by that point, any sound she made was a gurgling sound.

While Twilight’s transformation was going on, Celestia had made her way to the bed. She flopped upon it and landed on her back while simultaneously spreading her back legs. She lit up her horn and began playing with her nether lips. It had been some time since she had expelled a student from her school, but it was by no means any less fun. She rubbed a hoof over her now rounded belly, looking more like a pregnant mare and not one with a whole pony princess shoved inside her womb.

“It seems that your transformation is complete,” she cooed as she began targeting her magic directly onto her clit. “I’d take my time with you, but I’m afraid my own princess duties require speed and due diligence.” Celestia let out a loud cry of pleasure as her juices slowly dripped from her pussy. She cursed under her breath as she began to buck and writhe on the bed. Her clit was hypersensitive: a curse at some times, a blessing at others. This time it was a blessing, the large alicorn mare panting hard as sweat formed on her body. She tugged and pulled at her clit, feeling the inevitable pressure building. Just on the edge, she managed to speak through her loud moans.

“T-Twilight Spark…. Ungh! Despite being my mmmmm…. Most faithful student… Your failures and dis AAah~ pointments can not be overlooked. As such, as your mentor and… ooooooh… y-your principal, I revoke your title as Princesssssss…. And hereby expel you f-from my…. My…”

Her words devolved into one loud cry of pleasure as her back legs began to spasm. Her slit winked a number of times before a rush of fem juices spurted out. In the midst of her pleasure high, Celestia used her magic to direct the flow of her juices, tinged purple thanks to the melted mare, so that the puddle formed in the shape of Twilight’s cutie mark. Celestia panted hard from the exertion of her release, glancing at the purple puddle on the floor. She took a few minutes to recover before she stood up from the bed. She made herself up to look proper before turning to head out to the main hall. She took a glance back at the puddle and grinned.

“Perhaps I’ll have somepony come mop you up. Perhaps I’ll just let you dry there. Either way, enjoy your new life after expulsion,” she said simply before walking out into the hall and slamming the door shut.
