It was the start of a new day in Equestria, and to Twilight Sparkle that meant a new day on the unending quest for knowledge. She had just arrived at the school of friendship to teach a lesson. "Welcome to class, everypony!" Twilight greeted her students as they seated themselves. Most of the class smiled and mumbled a greeting back.
"Hi, Twilight!" exclaimed the Cutie Mark Crusaders. They weren't official students of the School of Friendship, but they visited occasionally to see what they were missing out on.
"We're going to be doing something very exciting in class today." Twilight thought for a moment, putting a hoof to her chin. "Well, I'll be doing something exciting and you'll be watching, but it's basically the same thing." She looked around the room eagerly, secretly thrilled that she would be able to showcase her physical prowess. She knew most ponies saw her as a skilled magician, but she had also gone through complex studies on healing and medicine with Princess Celestia in case something were to happen one day, leaving Twilight as the sole ruler of Equestria.
"So... does anypony have a broken hoof?" asked Twilight. There were murmurs and giggles, but nopony volunteered. "Really? Okay, no problem! Just wait here everypony. I'll be right back." With that, Twilight disappeared in a flash of purple light.
The Cutie Mark Crusaders turned to each other in confusion. "So uh, where do y'all think Twilight's gonna find a pony with a broken hoof?" asked Apple Bloom.
"I don't know, but she's smart so I'm sure she'll figure it out," replied Scootaloo.
"I mean, couldn't Twilight just go break somepony's hoof if she really needed to?" said Sweetie Belle, tilting her head. When her friends didn't reply, she realized she might have misspoken. She raised her hooves innocently. "Not that I think she would!" she added quickly.
"Uh..." Seemingly at a loss for words, Apple Bloom turned her attention back to the front of the room, where Twilight had reappeared with a large metal cage.
"Welcome back, everypony!" Twilight said excitedly. "Yes, Apple Bloom?" she asked as the young farm filly raised her hoof.
"We weren't the ones who left, so shouldn't we be the ones saying 'welcome back' to you?"
"That's a great point, Apple Bloom!" Twilight made her way to Apple Bloom's table with a smile on her face and leaned in close to the filly's ear. "Don't you ever fucking correct me in my classroom again. Do you understand, you moldy piece of shit fruit?"
The young Apple's eyes grew wide with terror and she nodded her head. "Y-yes Twilight, ah'm sorry. W-Won't happen again," she managed to squeak out.
"Good!" replied Twilight. "Now everypony, I'd like you to all welcome Cozy Glow back to our class for the day!" She gestured to the filly inside the cage. She was sitting in a wooden chair, all four legs restrained by Twilight's magical binds. A dark and sinister frown creased her face, and the look she was giving the class made many of the students squirm uncomfortably. They clearly remembered what Cozy Glow had done before her... departure.
Scootaloo raised her hoof. "Um, Twilight? I don't think she has a broken hoof," she pointed out. "How are you gonna show us this technique of yours?"
"That's ridiculous." Twilight opened the cage door and levitated Cozy Glow out beside her. She grabbed the filly's hoof, prompting a vicious snarl from her. However, hard as she tried, Cozy Glow could not escape her bindings. Twilight turned to the class, covering the caged filly with her own body. "Just give me one moment, everypony!" she said and teleported herself and the cage into the hallway.
Twilight slammed a hoof across Cozy Glow's face, warm pleasure washing over her as she heard the surprised cry of pain from filly. "Cozy, what did we say about the conditions of your parole?" She thought she saw a flicker of doubt flash in the pegasus's eyes, but it was replaced so quickly by a fake cutesie smile that she couldn't tell if her eyes were just playing tricks on her.
"I'm sorry, Princess Twilight," Cozy Glow said, her eyes watering with fake tears. "I'm just a little filly who doesn't know any better. I promise I'll take part in your demonstration if you just let me go." Suddenly, she spat at the princess. "Maybe if you let me out then I would be-- hey, what are you AHHHH!"
back in the classroom
"Uh, did y'all just hear that?" Apple Bloom asked her friends.
"Uh, you mean the noise that sounded like somepony screaming?" replied Scootaloo. "I think it'd be pretty hard not to."
"I have a bad feeling about this," said Sweetie Belle. She leaned in close in case anypony else was listening. "Maybe we should tell somepony about this, like Starlight." At that moment, Twilight poofed back into the room with Cozy Glow still inside the cage.
"Gather around, everypony! We're all ready for the experiment. Turns out Cozy Glow really did have a broken hoof and Scootaloo is an unqualified, stupid motherfucker who needs to keep her mouth shut!" announced Twilight, staring daggers at the orange pegasus, who gulped and averted her gaze.
The class crowded around Cozy Glow like visitors to a zoo. Despite knowing what she'd done, the three crusaders couldn't help feeling a little sad for her. She was just a filly, though one who had made much bigger mistakes than they ever had. Her front right hoof hung limply, and her jaw was clenched in pain. Sweetie Belle frowned. She hadn't remembered her looking like that when she first entered.
"Now class, I'm going to demonstrate how to fix a broken hoof. It's dislocated, so we'll need to put it back in place. Watch closely." Twilight reached out to take the filly's hoof, but Cozy snapped at Twilight as she did.
"Don't touch me, you purple dragon dick rider," she snarled. Her eyes grew wide as the purple glow of Twilight's magic engulfed her body. The princess turned to the class with a dark smile on her face. She snapped Cozy Glow's leg backward so hard that the tip of her hoof briefly touched the front of the limb, holding in laughter as the filly let out an ear piercing scream. Covering the class's view momentarily with her body, Twilight torqued the already broken limb, feeling a growing warmth in her groin as she heard several snaps along with the high pitched squeals coming from the filly. It was all very arousing.
The three crusaders just stared in shock with their eyes wide open. "I'm scared!" whispered Sweetie Belle.
"A-Ah think we gotta get somepony to stop it. This ain't right," Apple Bloom whispered back.
"Well I'm not staying here by myself!" said Scootaloo. "Let's just go before Twilight notices." The three fillies crept to the doorway, doing their best to ignore the sobs from Cozy Glow.
"Where the fuck do you three think you're going?" A shiver ran down the crusaders' spines at the sound of the cold voice behind them.
"Go Scootaloo, you're the fastest since you can fly!" said Apple Bloom, nudging the pegasus forward with her head. "We'll buy time!" But the pegasus turned her head indignantly.
"I can't fly, you shit for brains motherfucker!" replied Scootaloo.
"Oh, ah forgot. Well then I'll go." Apple Bloom slipped around the corner of the hall just as Twilight made her way over.
"Where are you two going?" asked Twilight.
Sweetie Belle and Scootaloo looked around nervously, fidgeting with their hooves. "Uh, washroom?" tried Sweetie Belle. The look of anger spreading across Twilight's face told her that was the wrong answer.
"You've been here long enough to know that the bathroom policy is ONE AT A TIME, and since it looks like Apple Bloom is out, you two can come back and watch the demonstration!" Without hesitation, Twilight teleported back to her position at the front of the room in front of Cozy Glow, this time bringing the two crusaders with her to the front row. She cleared her throat. "Since we're already here, it would be a waste not to get the most out of our subj-- er, volunteer! So today we'll also be going over the anatomy of a prepubescent female pegasus!"
Twilight used her magic to sit Cozy Glow belly up in the chair, each leg pinned outward to a corner of it. She ran a hoof over the filly's small wings, feeling her shiver underneath her touch. "Now there are lots of body parts of a pegasus, but we'll just go over the interesting ones." She slowly trailed her hoof down Cozy Glow's stomach, stopping just before she met her marehood. "The most sensitive part of a mare's body is the vag--"
"Stop right there, Twilight!" announced a new voice.
"Starlight?"
"Apple Bloom told me what you were doing in here, and I didn't have any choice but to come along." Apple Bloom's eyes widened as Starlight blew her cover. "You of all ponies know that these kinds of demonstrations aren't allowed... without also showcasing the reproductive system!" Starlight teleported over, her horn glowing as she prepared to cast a spell on Cozy Glow.
"What are you going to do to me!?" Cozy Glow cried in a shrill voice. For once, she seemed to realize she wasn't in full control.
"Oh nothing," said Starlight, giving her a comforting slap on the back. "In fact, I think you'll enjoy this!" She pointed her horn at the filly's clitoris and casted her spell. There was a bright flash of light, and then gasps from all around the room. Cozy Glow's clitoris had grown multiple times larger, and Apple Bloom could tell it was almost the size of Big Mac's cock. Twilight's eyes glowed in excitement. She prodded the organ with her hoof, drawing a gasp from Cozy Glow.
"Wow. Great job, Starlight!" The two unicorns hugged before Starlight went to leave the room.
"I've got to go masturbate. This is too much for me," said Starlight. And with that, she was gone.
Twilight turned her attention back to the class and Cozy Glow. The young pegasus was writhing in her bonds, and her breath came in laboured gasps. Twilight could tell she was very, very sensitive. Just one touch might send her over the edge, but that would be more a reward to her than anything. "Now watch, class. Sexual desire is a very powerful thing, and we will see that today by making Cozy Glow lose her mind by doing absolutely nothing."
A minute passed. Cozy Glow's marehood was now dripping with her own arousal. She squirmed in her bonds, but to no avail. Moaning in agony, she thrust her crotch in the air, but it only frustrated her more when she realized she couldn't get any stimulation at all. The class was watching intently. A few minutes later, she had tears in her eyes from her horniness.
"Is something wrong, Cozy Glow?" Twilight asked.
"I WANT YOU TO FUCK ME!" screamed the filly.
Twilight put a hoof to her chin. "What's the magic word?"
"JUST STICK IT IN MY VAGINA YOU MOTHERFUCKER!" Cozy Glow could no longer think about anything but the burning desire in her pussy. Twilight's eyes darkened at the desperate comment.
"I'll do better, Cozy."Twilight grabbed the writhing filly's enlarged clitoris in her hoof and squeezed. It was slick with Cozy Glow's own vaginal fluid already. An unearthly cry of pain and pleasure escaped form Cozy Glow's lips. "Class, this is an orgasm. It happens when sufficient stimulation has been given to an erogenous zone!" She pumped her hoof up and down, and the pegasus began spasming in her bonds. A high pitch screech filled the air as she came, spraying clear fluid all around the room, but Twilight didn't stop. She held the filly down, continuing to stroke her clitoris over and over as her body started shaking. Suddenly, she stopped moving altogether.
"Oh fuck I think I killed her"
