A Quick Lesson
"Hi everypony! So, today we're going to be talking about a very special topic," said Twilight as she started class. She cleared the chalkboard and turned to face the students. "Now some of you may have heard about this from your parents, but I know this is going to be a new topic for a lot of you." She drew a long penis and a vagina on the chalkboard. "We will be talking about puberty today."
There were murmurs across the room, some of confusion and others of excitement. "My dad showed me his penis!" exclaimed one of the colts.
"My mom showed me her vagina once!" said a griffin.
"Um, Princess Twilight?" asked Yona the yak. The princess turned to her with a smile.
"What is it, Yona?"
The Yak tilted her head questioningly. "I have two dads, but one of them has a vagina. I thought only females had vaginas?"
Twilight's eyes instantly darkened. "The fuck is wrong with you? Don't ever say that shit inside my classroom again!" she screamed so loudly that Equestria itself shook slightly.
"What was wrong about what I said?" asked Yona, cowering in her seat.
"Don't play dumb with me, you fat piece of shit!" growled Twilight. "The only thing I hate more than gays is creatures who can't make up their mind about who they are. In fact..." Twilight clapped her hooves to get the attention of everypony in the room. "LISTEN UP, YOU STUPID FUCKERS. We are starting today's lesson, and we are going to cover a variety of topics, so listen well." She pointed to Yona, who was sulking at her table after being screamed at. "Yona has something she would like to share with you all today!"
The yak's eyes widened in surprise. "M-Me? No I don't," she said shakily. The glare Twilight gave her nearly made her shit herself though, and understanding followed after. "O-Oh, okay I guess..." Yona walked to the front of the class slowly and took a deep breath. "Um hi everypony, my name is Yona."
"Tell us about you parents, Yona," Twilight said smugly.
"Well, my parents love me a lo--"
"SHUT THE FUCK UP AND TELL EVERYPONY HERE YOU HAVE TWO DADS!" screamed Twilight.
Yona flushed and lowered her gaze. "I think you just did," she muttered.
"That's right!" said Twilight in a singsong voice. "Now, I would like everypony here to know THAT'S FUCKING WRONG! And even worse, one of her dads has a vagina, which is what we will be learning about today!" Twilight used her magic to draw a detailed image of vulva on the board. "Now, does anypony here know what this is ca--" She stopped as she heard a strange squelching noise from the back of the room.
"Mmm, hnng, ah, ah... Rainbow Dash!" There was a muted cry followed by heavy panting, and all eyes turned to the back of the room where Scootaloo was sitting with her legs spread wide open. Apple Bloom and Sweetie Belle were watching her curiously. Twilight stalked up to the fillies and slapped Scootaloo right in the vagina, causing her to scream in a mix of pain and pleasure.
"Scootaloo, why the fuck are you masturbating in my classroom?" Twilight asked. Surprisingly, she was rather calm about it.
The pegasus looked at her proudly and announced, "Rainbow Dash taught me all about this when we were alone in the summer! Look everypony," she spread her cunt open, "this is a vagina!" She rubbed her hoof over it and moaned. "Rainbow Dash taught me how good it feels to massage it, and it feels even better when somepony else does it for you," explained Scootaloo.
Twilight clapped slowly. "Very good, Scootaloo. Since you know so much, would you like to volunteer to be a part of today's health lesson?" she offered.
"Um sure," said Scootaloo, getting out of her seat and going to the front of the classroom beside Yona.
"Get the fuck out of here," Twilight told Yona. The yak's eyes watered and she ran out of the room crying. Twilight let out a sigh of relief. "I never liked that bitch anyway," she said. "Now Scootaloo, please come sit in this special chair for me." A sturdy looking wooden chair was levitated over by Twilight, which the filly sat on eagerly. At that moment, a wicked expression crossed Twilight's face. "Good, now just to make sure there are no interruptions..." Twilight's horn glowed purple as she created four magical binds, pinning each of Scootaloo's legs to the chair, making sure to spread them wide and expose her stomach.
Scootaloo gulped. "Twilight, what's happening?"
The princess gave her a reassuring look. "Don't worry Scootaloo, this is part of the demonstration! Now class, take a good look at this." Twilight reached forward and spread the filly's pussy outward, exposing the soft pink flesh on the inside. "Now watch what happens when you touch it." Twilight traced a hoof over Scootaloo's marehood, which was already slick with fluid from her masturbation session. The filly moaned, closing her eyes. "Unlike males, females can have more than one orgasm at a time," explained Twilight.
Sweetie Belle raised her hoof. "Um, what's an orgasm?" she asked.
Apple Bloom nodded in agreement. "Yeah, ah never heard of no orgasm before!"
Twilight rubbed a hoof along Scootaloo's stomach, causing the filly to shiver under her touch. "That's a very good question, you two. Let me demonstrate." She brought her mouth to the pegasus's quivering marehood and licked it, slowly and deliberately. Scootaloo thrashed in her magical bonds, her breath coming out in shaky gasps. Twilight motioned to her face. "This is how you can tell she is enjoying it!" She flicked the filly's clitoris, causing her to scream. "This is the most sensitive part of a female's body," said Twilight, grasping it gently between her teeth. She sucked on it, rolling it on her tongue.
At that point Scootaloo could no longer speak. Her mouth hung open in a permanent expression of pleasure, and her eyes widened as her orgasm approached. "RAINBOW DASH, I'M... CUMMING!!!!" she screamed at the top of her lungs as Twilight continued to suck her vagina to the end of her orgasm. Clear fluid sprayed onto Twilight, who reared her head back in response.
"I DIDN'T SAY YOU COULD CUM!" shouted Twilight. "Bad fillies deserve punishment," she seethed, magically generating a vibrator. She stuffed it in Scootaloo's vagina and turned it to the highest setting. The effect it had on Scootaloo was immediate. The filly's eyes rolled to the back of her head and she thrashed and convulsed in her chair, screaming over and over for mercy. However, Twilight teleported her to a corner of the room and made her way back to the front of the class. "I hope you all learned a lot today," she said with a smile. "Class is over."
"Um Twilight, doesn't you doing those things with Scootaloo make you gay?" asked Sweetie Belle.
"Of course not!" responded Twilight. "I've already fucked Shining Armour before, so I can't be gay."
"Ah get it! It's kind of like how Applejack has taken Big Mac's cock in her before an' that's how it ain't gay when Granny Smith goes down on her!" exclaimed Apple Bloom.
"That's right!" said Twilight, giving each filly a pat on the head. Scootaloo remained tied to the chair for the rest of eternity, orgasming until the end of time. Over the years, her squirting flooded Equestria and all the ponies were forced to flee to the moon.
