Twilight's Science Class

Twilight sat sadly in front of her castle’s furnace, her friend’s body burning. She rubbed a hoof across her muzzle-she wanted to give Fluttershy a proper buriel, but even if the princesses pardoned her, the trial would ruin Twilight forever. And then...there was the other issue…

Her gaze wandered to the stairs. She wanted to do more science. She wanted to write more on the workings of ponies...but most of all...she wanted to feel that tingling in her nethers as she did so. Was it just the cutting open of the ponies? Was it the life, held in her hooves? Was it the pain they might die in?

She was appalled to realise, when she looked back, she was upset at how little Fluttershy had suffered. She got up, pacing. This...this had awoken something in her. She was afraid. She was exhilarated. She was...aroused.

She went up the stairs slowly, deep in thought. Well...one of the elements was dead...so it didn’t matter if more were...so what if she, just...kept experimenting on her friends? Looked at how the three pony tribes varied.

She came back to her senses in the foyer, mulling it over again, when Rarity trotted in.

“Oh, darling! Have you seen Fluttershy? She was meant to met me at the spa after getting that book she wanted?”

Twilight went pale under her fur. A witness...well. The choice was made for her.

She faced Rarity, and sent a bolt of magic at the other’s horn, leaving a crack from base to tip. Rarity convulsed, screaming, and passed out from the massive pain of horn trauma. Twilight lifted her in her magic, carrying the unconscious unicorn down the stairs to her lab.

She laid out the dress horse on the same table where Fluttershy had passed, using leather straps to keep her still. She prepared her tools, taking long enough Rarity awoke, sobbing immediately.

“It hurts, why does I-w...wah...where am I? Why am I tied do-Twilight! Please, release me, we have to report whomever has done this!”

“It was me, Rarity...I’m sorry, but I need to...to get off to this! I mean...science! Yes, science!” When she turned to collect her tools, Rarity could see just how much of a lie the latter was. The princess’ tail was hiked up, fun goo drooling profusely down her thighs, like she was in heat.

“T...twilight, please...we can...talk about this surely? I...” she thought hard, but there was little she could bribe a princess who lived in a crystal castle with. “I can help?”

“Don’t be silly, partners increase the danger of being caught, and I don’t plan on getting caught. I’ve thought of alibis for all six of you! Seven, if I can get my hooves on that fake magician Trixie...” she grumbled.

“...dear Celestia, are...are you...going to do this to everyone?!”

“Of course I am...and then maybe my self, too-it’ll be hard to pull myself apart AND record it all, but I believe in myself!”

“Twilight, enough! Listen to the madness you’re spouting!”

“...you’re right, it is madness...and it...feels so good! No wonder Discord wanted us all to feel this, it’s amazing!” She pranced over to Rarity, a chisel and hammer in her magic, as well as a journal and everything needed to write in it.

“Now, please be open and vocal about how it feels, this is for science!” she positioned the chisel at the tip, “I’ll take it piece by piece, and record the bits and what it looks like inside! This will give me great data on traumatic horn damage as well,”

“...Twilight...Twilight please, no...I don’t want this!”

Twilight huffed, “Well, that is hardly generous, Rarity!” Somehow...Rarity felt she was right- she should be more generous, and what higher generosity than giving her life so generations of ponies would know more, and not have to under go such pain?

“...very well-just please forgive me if I cannot keep a lady like composure.”

“Of course I will!” she stroked her friend’s mane with a hoof comfortingly. “And as painful as this will be, I won’t hold it against you,” she promised, before replacing the chisel, and giving it a solid whack.

Rarity screeched with such pain and horror Twilight wondered if she’d turned the poor mare feral, before Rarity begged to be let out of her pain. She seemed to come back to herself, shaking her head- or trying to before the jolted tool in her horn hurt far too much. Twilight made notes, asking questions and writing as Rarity as best she could through tears and agony.

Twilight struck the horn again, and it cracked right off, in many pieces. Rarity’s eyes rolled back in her head, and no matter what Twilight tried, she couldn’t bring Rarity back to her senses. Not shocking, not smelling salts, nothing. The closest she got to a reaction was when she poked the horn’s remains. This intrigued Twilight, and she got a few more tools.

She sat on Rarity’s barrel, blushing heavily, but the table was too small for much else. Book held in magic, she made notes in it again as she placed a nail in the horn stump, carefully hammering it in. Rarity jerked, Twilight rubbing against her before stilling her hips with a fair amount of shame. She cast an electricity spell at the nail, watching Rarity convulse, making notes on it.

She sighed-interesting, but not all that helpful. She got down from the table, pacing as she thought deeply. “Hmm...still, this is good...oh, of course!” she began vivisecting the unicorn as she had Fluttershy, pulling her apart, making notes and drawings. Unicorns seemed lithe, but not as light as Pegasus ponies-most likely their inherent magic for flight.

“I wonder how it compares to earth ponies...” she mused, as Pinkie popped out in typical Pinkie fashion from the doorway- covering the room in confetti.

“Heya, Twilight! I- oooooh, we’re doing THAT sort of fic, huh?”

“...I...what?”

“Well that’s cool with me! Can I request a science?”

“...yes?”

“I wanna die the way I lived- eating waaay too much! Feed me till I pop, Twilight!”
