Lesson 1: Anatomy Demonstration

Previous ChapterNext Chapter

Feeling the eyes of all her classmates on her back, Scootaloo made her way to the front of the classroom until she stood next to Shining Armor. He was so much taller than her, and Cadance so much taller still. But she ruffled her wings and stood proudly at the front of the class, refusing to feel nervous about it after volunteering so readily.

“Now class,” Cadance said sweetly, “can anypony tell me the main physical difference between mares and stallions, between fillies and colts?”

It was Twist, of all ponies, who raised her hoof. “Boys have penithes and girls have vaginas?”

“Yes, yes exactly. I can see somepony has been studying ahead at home!” Cadance smiled warmly. “Although, technically, the correct term for more than one vagina is vaginae.”

Scootaloo fidgeted in place, even though she didn't really feel like the center of attention anymore. It still felt awkward being in front of the class, being an exhibit.

“Um... you mean hoo-ha and dingaling, right?” Apple Bloom asked without waiting for Cadance to call on her.

Scootaloo was probably the only one who noticed Diamond Tiara's eye-roll at that question.

Cadance giggled a little. “Well, because some ponies feel uncomfortable talking about these things, they've been given a lot of different names and euphemisms – which are words that replace words that ponies think are rude. A mare's parts are sometimes referred to as a marehood, her flower, a pussy or kitty, cunt or cunny, or a honeypot. And a stallion's parts are sometimes called his member, a cock, a dong, a dick, or a stallionhood. Of course, there are many other names, too many to go into right now, even hoo-ha and dingaling.” She gave Apple Bloom a sly wink. “I imagine you learned words like that from your sister teaching you about farm animals?”

“Learnt 'em from the sheep themselves, actually,” Apple Bloom said, earning her a giggle from around the classroom.

“Ah yes, I do know sheep can be dirty talkers. Though they rarely have much to back that up with.” Cadance shook her head. “But anyway, how many of you know what those parts look like, and what they do?”

Only a few hesitant hooves rose among the students.

“That's okay. It's what you're here to learn today, after all.” Cadance turned to the side, toward Shining Armor. “Hubby, if you'd be so kind...” She gestured toward the teacher's desk.

Shining Armor's cringing blush returned full-force. Scootaloo almost thought she could feel the heat of it. He shuffled over to the desk and sat on the edge of it, facing the class and crossing his hind legs modestly.

Cadance gave him a look that spoke of some discussion the two of them had been through already, and he opened his legs.

A collective taking of breath – not quite a gasp – passed through the class. Scootaloo rushed around to the front of the desk so she could see what all the fuss was about, too.

So that was what a boy looks like... Scootaloo stared hard at his empty-looking sheath and the big smooth balls below. It was surprisingly similar to what she had, and a little gross, but there was something about it that made her not want to look away, that made her want to see it even closer. For some reason, it was getting a bit hard to breathe, and she was getting a weird little tickling sensation under her tail. Almost without noticing, she stepped closer ... and closer...

Cadance's hoof stopped her. “Easy there, Scootaloo. This one's mine. You'll have to find your own, or at least ask permission and find out if I'm okay with sharing.”

Scootaloo shook her head clear and took a few steps back. What had she been doing? What did Cadance think she had been doing?

“Can everypony see well enough?” Cadance looked around the classroom, then turned back to her husband. “Let's start by identifying the parts you can see now. The most obvious part of a non-aroused stallion is his balls, which are these two round things down here.” She pointed them out. “They produce his sperm – we'll get to that later – and they also can make a stallion feel good when they're touched. You should be gentle, though, especially with a stallion you're not familiar with; the balls can be very sensitive, and if you're too rough with them, it's very painful for the stallion.”

Cadance's hoof moved up a little. “The other thing you'll notice is his sheath. This is an envelope of skin his penis hides inside of when he doesn't need it. Touching it can also make a stallion feel good a little, and it's much less sensitive, so you don't have to be as gentle as you are with the balls. The sheath isn't really any more sensitive to pain than any other part of the body.”

“But where's his penis?” one of the students asked. “I don't see it.”

“A stallion's penis usually stays hidden away inside his sheath unless he's about to pee, or he's turned on and getting ready for intercourse – sex. I'll explain that in a little while; let's not get ahead of ourselves.”

“Um... Cadance?” Shining Armor said. “Do I need to...?”

Rather than answer him directly, Cadance addressed the class again. “Thankfully, the penis usually isn't too difficult to coax out of the sheath. All it takes is getting the stallion aroused. You can do that by putting on an erotic display – showing him something he's attracted to – or by stimulating him – making him feel good – or a mix of both. For the sake of an example, let's do both.” She turned to Scootaloo. “Could you please stand in front of him, facing away, and lift your tail up nice and high? It wouldn't hurt to swish your butt back and forth a little.”

It felt a bit weird to do it, but Scootaloo did as Cadance said, lifting her tail for Shining Armor. Somehow, she felt more exposed this way than she had in front of the whole class. A thrill of nervousness shot through her, but it was a thrill – some twinge of excitement that made no sense, but somehow made her want Shining Armor to look at her privates. She lifted her tail higher and swished it back and forth, looking back at him in what she hoped was a seductive way. He stared back at her, with wide-eyed fascination, and a little hint of confusion, oddly enough.

Cadance edged in close to Shining Armor and whispered into his ear, probably too quiet for the rest of the class to hear, but Scootaloo was much closer. “You like that little filly's pussy? You like her tiny little ass?” She looked down at his sheath as it began to bulge out, and she smiled. “You do like it. Such young and tender fillies. Maybe if you're good, I'll let you have one of them. Which one do you want?” Her whispers trailed off as she slid her face slowly down his belly, until her lips were brushing the top of his sheath, where she paused for a moment, glancing at Scootaloo.

Though she was still presenting herself to Shining Armor, Scootaloo had lost her seductive gaze and was instead staring and gaping at them.

Giving Scootaloo a lascivious wink, Cadance licked her husband. First, she just lapped at the rim of his sheath, but she soon moved lower down, nuzzling against him as she tenderly caressed his balls with her tongue. When he began to bulge all the way out of his sheath, she pressed her lips over the top of it and let him grow right into her mouth. A little bit of drool dripped around the edges, and Cadance's cheeks expanded ... and then her throat.

When Cadance pulled herself off of him, she had to crane her neck at a weird angle, letting inch after inch of him slip out of her mouth.

Scootaloo had seen a stallion's cock before, of course, but only from a distance, and that was just a stallion peeing. She'd never seen one so stiff before. It bobbed in the air, black mottled with pale spots and glistening with Cadance's spit. It was strange, though ... she always thought it would look different than hers.

Cadance cleared her throat conspicuously. “There, class, is a stallion's penis, and a very fine specimen, if I do say so myself.” She winked at Shining Armor. “Can you all see the way it curves slightly toward his belly? Good. With him nice and hard like this, you can even see a little of the three lobes within its round profile – look here near the base, how it has slight indentations.”

It pulsed and twitched under the whole class's watchful eyes.

“This ring around the middle is called the 'medial ring', and let me tell you, it feels wonderful when it rubs back and forth over your clitoris.”

One of the colts in the class – Button Mash – raised his hoof.

“Don't worry,” Cadance said, “we'll get to the female anatomy in a moment, and then you'll learn what a clitoris is.”

Button's hoof went back down.

“You'll notice that below his medial ring, there are lots of bulging veins – those also can feel pretty nice. Above it, it's nice and smooth, all the better for sliding in. And then we come to the tip, or flare.” Cadance poked at the top of Shining Armor's cock with her hoof. “It's a little wider than the top part of the shaft, and has a little fringe of bumps around the edge that will provide wonderful stimulation for you fillies. In the center of the tip here, you'll find a smallish hole – this is where the semen comes out.

“But what's it all for?” Cadance didn't wait for the class to answer. “The main purpose of a stallion's penis is to penetrate inside a mare and deposit his sperm inside – though that's hardly their only use!” She came around and stood sideways to the class, raising her tail. Scootaloo got an excellent view of her, even though they weren't studying mares yet. Cadance winked at her husband. “Shining Armor will now demonstrate how a penis is used.”

Shining Armor started. “Um, now? Right in front of them all?”

“Uh huh.” Cadance lifted her tail higher, flipping it over her back.

He looked a little like he was in shock, not blinking enough and trembling a little, but he did get off the desk and come around behind Cadance.

“This is the classic type of intercourse, and it's still the most common,” Cadance said, “but let's just focus for know on what Shining Armor is doing with his penis.”

Shining Armor lifted up his front hooves and set his chest down on Cadance's rump. His cock bobbed up and down just below her tail.

“The stallion mounts on top of the mare like this, and he gets his penis lined up with the opening of her vagina. It has to be nice and hard in order to penetrate, but once he finds the right spot, he'll—” she gasped as he lunged forward “—he'll push his penis inside her vagina.”

He pushed back and forth a few times, each time sinking deeper into his wife. Scootaloo stared – she had a front-row view, almost close enough to the action to reach out and touch. She could see the wet black skin of Shining's cock sliding into Cadance's winking and dripping pink pussy.

“Depending on the size of the mare and the size of the stallion, he may or may not be able to fit his whole length inside, and he may or may not be able to stimulate every part of the mare. If he's too big, it can be painful for the mare, both from the stretching around his girth and from his tip hitting her cervix.” Cadance's head dropped a little lower as she pressed back against her husband. Her breaths were coming in little gasps. “But in the case of me and Shining Armor—”

He shoved himself forward, all the way until his thighs pressed against Cadance's butt.

Cadance moaned a little. “We're a perfect fit.” She was quiet for a little while, other than the little gasps and groans she made as she was filled over and over. “Shining,” she said quietly, “pull out when you're close.”

Grunting his dissatisfaction, Shining Armor pulled out of her right away, his length dripping with Cadance's honey as it slid out of her. Scootaloo was surprised when the tip of it stuck for a moment and then popped out forcefully.

Out from under him in a moment, Cadance used her magic to sit Shining Armor back on the desk. “Now you all can see what a stallion's flare really looks like. This happens when a stallion is almost ready to orgasm.”

Scootaloo stared, her mouth gaping. The flat tip of Shining Armor's cock had swollen out wide, two or three times as wide as the rest of it.

“The flare serves a few purposes. First, and most importantly to all of you, it feels incredible inside when it swells up and stretches you out, when the little ruffles around the edge of it are pressed against you in just the right spot as he moves...” Cadance's eyes drifted closed a little for a moment, and she bit her lower lip slightly. She soon recovered, though. “But it also plays a couple important biological roles. First, it makes the penis more difficult to pull out, helping make sure it stays in for the critical moment. Second, it forms a seal between itself and the inner walls of the mare's vagina, so that when he orgasms, his semen – the white liquid his sperm is in; we'll get to that in a moment – his semen is forced to go deeper inside the mare, where it needs to go, rather than coming back out around the sides of his penis.”

Shining Armor moaned a little, and his legs flexed, squirming in place.

“As you can see, leaving a stallion in a state of almost orgasming is uncomfortable for him.” Cadance's face moved close to Shining Armor's cock, almost touching him. “I'm going to stimulate him a little more, and then we'll demonstrate a stallion's orgasm. An orgasm is the climax of a sexual encounter, and it's one of the greatest feelings you'll ever experience. When one happens to a stallion, muscles inside him will contract and he'll squirt out a sticky white fluid called semen, which is full of his sperm. Observe...” She leaned in just a little closer and started licking his cock, long slow licks from bottom to top. Her tongue pressed heavily against him, leaving wide trails as she slid it across his shaft.

Scootaloo noticed a face in the window. It was Princess Twilight! Was she going to be lecturing here, too? But no, she was just there, watching. She was eagerly staring at ... Shining Armor's cock! Scootaloo's eyes went wide at the realization. Who would have thought Twilight Sparkle could be interested in that?

But Shining Armor soon took back Scootaloo's attention with a progressively louder series of grunts. He threw his head back and arched his body, lifting himself off the desk a little as Cadance continued to lick him.

She gave him one last lick, then pressed her lips against the side of his shaft. Shining Armor jerked. His cock spasmed, and a fountain of white goo shot out from the tip.

Cadance deftly sidestepped the spray, but Scootaloo wasn't so prepared. The thick strands and globs of it splattered right onto her face. She jerked away, trying to blink it away from her eyes, and she did manage to avoid the rest of it, five more big splurts that plopped onto the floor in front of her, but it was too late. Her face was covered in Shining Armor's cum! She couldn’t even keep her eyes open.

Shining Armor dribbled out his last, gave a huge sigh, and then fell backward onto the desk.

“There. This is a stallion's semen, sometimes called cum or jizz, or several other names. After he—” Cadance saw the state Scootaloo was in. “Oh dear. I'm so sorry, here, let me help you with that.”

Something warm and soft touched Scootaloo's face, a tongue! Cadance was licking the cum off of her, little by little, humming softly to herself as she did.

In a few moments, Scootaloo's face was clean again, or at least as clean as licking could get it. She opened her eyes and smiled back up at Cadance. “Thank you.” When she looked at the window, though, Twilight was gone. She'd just have to keep it to herself that she saw Twilight watching. Nopony else would believe her.

Cadance returned to her husband's side. “For a stallion, an orgasm is usually the end of his sexual experience, because once he has one, he quickly loses his arousal, and his penis softens and retreats into its sheath.” She held up his cock in front of the class. It was slowly shrinking and flopped limply in her hoof. “It also often makes the stallion very tired, sometimes even putting him right to sleep.” She nudged Shining Armor's leg. “Hey, wake up!”

With a snort, Shining Armor rose back up to a sitting position, though he still wavered drowsily back and forth. She shooed him off of the table, and he stumbled over to the teacher's chair and promptly fell asleep again.

“Now Scootaloo,” Cadance said, “let's progress to the mare's anatomy portion.” She lifted Scootaloo up with magic and set her on the desk where Shining Armor had been. The spot was still warm. “Now class, if you'll look right here, you'll see...” As Cadance motioned with her hoof, she stopped suddenly. “Wait, what?” Her eyes went wide.

Scootaloo felt a blush coming on, her cheeks heating. The whole class was staring at her, their mouths gaping. She'd always secretly assumed that she was somehow wrong, but...

“Mithuth Cadance?” Twist asked. “I thought fillies didn't have penithes.”

Scootaloo's cock was still mostly stiff from having watched Cadance and Shining Armor, not to mention the feeling of the Princess's tongue on her face. It stretched half-limp over her belly, her tight little balls hanging below, almost concealing her pussy. She looked down at it and cringed.

Cadance recovered from her shock quickly. “No, no don't be ashamed, Scootaloo. You're a very special filly.” She raised Scootaloo's chin up with a hoof, making Scootaloo look into her eyes. “Class,” she said, still looking straight at her, “Scootaloo is what is known as a Futanari, sometimes called a futa for short. They're sometimes also called hermaphrodites or herms. It's nothing to be ashamed of. In fact, she should be very proud.”

Scootaloo blinked up at her. Proud?

“Futanaris are very rare, and they're also very special because they have both a mare's parts and a stallion's. That means they can experience sex as a mare, or as a stallion, or even both at the same time. It's an incredible gift, and we should all count ourselves lucky to have such a filly in our class. In all the hundreds of classes I've taught, I've only seen five fillies like this.”

Huh. After that, Scootaloo did feel a bit proud of herself. But she was still blushing.

“I'm afraid, though, that it means I'll need to ask for another volunteer. As wonderful as Scootaloo is, she's a special case, and I need to find an ordinary filly to demonstrate what an ordinary mare is like.”

Well, there went her pride. She was officially weird. Scootaloo slipped off the table and down to the floor. Her cock slipped back inside her sheath.

Although a few hooves were hesitantly rising among the class, Cadance took the time to stop Scootaloo with a hoof over her shoulders. “Don't feel bad, Scootaloo. You'll have your time to shine.” She leaned in a little closer and whispered, “And maybe I'll get to feel your wonderful little filly cock inside me.”

Scootaloo's eyes widened at the thought of doing that to a princess, and she rushed back to her desk before her cock could come out again and betray her thoughts her classmates.

Cadance's attention returned to the class, and she picked one of the raised hooves. “You, yes ... what's your name?”

The little grey filly trotted to the front of the room, her head held low. “Dinky Hooves, Ma'am.”

“Don't be shy, Dinky.” Cadance lifted her up and set her on the desk where Scootaloo had just been sitting. “We're all going to know each other quite well by the time this is over, so there's no need to hide yourself. Now, lean back a little... Yes. And spread your legs out...” Cadance nodded, then turned back to the class, pointing with a hoof. “This, class, is what most fillies look like. A mare's genitals are much less showy than a stallion's, but they're no less important or less fun to have.”

Dinky flinched a little when Cadance touched the top of her puffy little pussy.

“The outer surface here is called a vulva, and it stretches all the way from here down to her anus here.” Cadance's hoof slid gently down, pointing it out. “Now, going back up, you'll of course notice the two outer lips. They're plush and soft, and they feel good when they're touched.”

As Cadance's hoof traced its way across, Dinky's legs twitched a little. She was breathing a little too fast.

“You can see that at the end, the two lips of her vulva come together into this little bulb. Just under there is her clitoris, which we'll get to in just a moment.” She took her hoof away, but then her horn glowed. Dinky's pussy lips spread open in a magical blue glow. “The really important parts are inside.” She pointed to the big gap in between the fleshy lips. “This is the entrance to her vagina. You see these two pink walls closing in on either side? They can actually spread much further and much deeper. Allow me to demonstrate.”

Scootaloo stared as the blue magic went deeper inside Dinky, lighting its own way and spreading her out on the inside, too. She tried to ignore the way her cock was growing again, and as she'd long practiced doing, she nonchalantly more-or-less hid it by crossing her front hooves in front of her on the chair and pressing it against her belly.

“Just a little way inside, there's a round opening... There. There it is. That's the barrier between the entrance of the vagina and the vagina itself. Beyond that, it gets a little wider and much softer, perfect for pleasuring a stallion.”

Dinky squirmed, and her pussy flexed itself open and shut again.

“Ah, good!” Cadance released her magical hold, letting Dinky's slit close again. “That was what's called a wink. Let's see if I can coax one out of her while she's not stretched out, so you can see what it normally looks like.” She caressed her magic lightly up and down over Dinky's pussy.

It winked again, only the uppermost part of it flicking open this time, showing the class a flash of pink before it closed back in on itself.

“Isn't that lovely?” Cadance tickled her a bit more, eliciting another wink, a whole series of them. “Winking like this helps spread lubrication over the outside of the vagina, and it can be a way for a mare to attract a stallion's attention and arouse him. It also can play an important role in his initial penetration, exposing the slippery inner parts for him to press into rather than the outer lips, which might still be dry.”

From the front row of the class, Pipsqueak spoke up, “Lubrication?”

“Ah, yes, we haven't discussed that yet, have we? An important role for the mare's parts is to produce most of the lubrication to make sex nice and slippery. Believe me – you don't want things getting stuck or getting friction burns there. Hopefully by now...” Cadance leaned in to take a close look at Dinky's pussy. “Yes, good. It's not very much yet, but if you look closely, I'm sure you'll see it. This clear fluid leaking from her vulva is her natural lubrication.” She swiped a little of it up with the tip of her hoof and showed it around to the class, making a pass around the front row. “The more aroused a mare gets, the more of this she'll produce, and for the most part, the more the better. Of course, you can also just use artificial lube if you need to, but that's another lesson.”

“Miss Cadance,” Dinky asked, “um, I'm feeling kind of weird down there, so can I please—?”

“That's perfectly normal.” Cadance returned to her. “And we only have a couple more things to show the class, so I'll help you with that feeling very soon.”

Dinky nodded, though a little uncertainly.

“The only other external features special to mares are the teats.” Cadance pointed to one of the tiny little nubby nipples under Dinky's belly. “They're also sexually sensitive, though not as much as the vagina itself, and you can make a mare feel good by rubbing them, licking them, or even nibbling or pinching them, though you need to be gentle when you're doing that.” She demonstrated with a little lick along the closer one, which occasioned another wink. “Stallions don't have them, and unfortunately for Scootaloo, neither do futanaris.”

Scootaloo hung her head low in shame ... and also, privately, to look at herself, on the weird feeling that she'd look there and notice something she hadn't seen before. But no, everything was just how she remembered it.

“A mare's teats will stay small for most of her life, but they will swell much larger – and get much more sensitive – if she becomes pregnant.” Cadance used her magic to spread Dinky open again. “Now, I've saved the best part of a mare's anatomy for last. Can anyone guess what it is?”

The class was surprisingly silent, but Scootaloo had been paying attention, even if nopony else had. “The clitoris?”

“That's right, Scootaloo!” Cadance's smile for her contained far more underneath it than the mere satisfaction of having a good student.

“The clitoris, or clit, is by far the most sensitive part of a mare, and it can make her feel good in ways nothing else can even come close to. The clitoris is a little nub of flesh located right ... here.” Cadance pointed with her hoof between the outspread lips of Dinky's pussy, near the very top. A heart-shaped pink bump was indeed there; it throbbed outward as Dinky winked again. Cadance began slowly caressing it with her magic, ever so gently. “Stimulating the clitoris is – for most mares – the key to achieving orgasm.” Her magic still working, she came in close to Dinky's face. “Have you ever had an orgasm before, Dinky?”

Dinky's forelegs were trembling as she braced herself up against the surface of the desk. Her chest heaved up and down. Looking over at Cadance with a wide eyed mix of fear and wonder, she shook her head no.

“Now, the clitoris can easily be overstimulated and become uncomfortable, even painful, so you'll need to start off slowly and gently, working your way up to what the mare is comfortable with, which is different for each one.” Cadance smiled, and her magic's stimulation intensified a little. “How does that feel, little one?”

Dinky gasped, fell back onto the desk, and squealed. Her legs spasmed in sharp jerks and her belly heaved. The soft skin of her pussy bulged in and out, getting even wetter.

“That, class, was a female orgasm.” Cadance looked quite pleased with herself, and she stopped her magical stimulation. “The vagina contracts repeatedly, as well as most of the pelvic muscles, and it feels incredible for the mare. Could you tell the class how that felt, Dinky?”

The spent filly gave an ambiguous bleat and waved a hoof upward.

“But the truly wonderful thing about a mare's orgasm is that while a stallion needs time to recover from his orgasm in order to have another, for mares, having one makes it easier to have another.”

Dinky gasped as Cadance's magic began working on her again.

“What I'm doing here is a simple spell to rub Dinky's clitoris and move it back and forth a little. This can also be done with a tongue or a well-lubricated hoof – I'm just using this method in order to avoid blocking your view. Now of course, while the clitoris is a mare's most sensitive spot, it isn't her only sensitive spot, and the experience can be made even more intense by stimulating her in multiple ways. Observe...” Cadance's magic reached out to caress both of Dinky's nipples, then it branched down to rub her entrance as well. As soon as Dinky winked again, Cadance formed her magic into a long, round shape and plunged it deep inside the little filly.

Dinky gasped and moaned, writhing on the table.

“With this much stimulation, it probably won't take long. Watch closely, class.”

She was right. Dinky's movement became jerkier and less controlled, and soon she cried out again, arching her back up against the table. A huge spray squirted from inside her over the front row of the class, then died down and dribbled onto the desk.

“Ah!” Cadance smiled and let her stimulation stop again. “I'm glad you all got to witness that. What you just saw is a squirting orgasm, where the contractions inside the mare become so intense that she loses control of her bladder.”

“Wait,” Pipsqueak cried out, “so she just peed on us?”

“It's perfectly normal for this to happen to a mare, and it should really be taken as a compliment at how good of an orgasm she's just had. Keep an open mind, and you might come to enjoy seeing a mare so satisfied.”

The class was quiet for a moment. Scootaloo herself wasn't sure – she could understand what Cadance meant about it, and maybe it was kind of sexy ... but all the same she was glad that she wasn't among the ones who'd gotten sprayed.

Cadance looked down at Dinky, who was laying flat and limp, her chest still heaving, and smiled warmly. “In theory, there's no reason a mare can't have an indefinite number of orgasms in a row. In practice, though, orgasms take a lot of energy, and most mares will find themselves getting pretty exhausted after just a few. I think Dinky here has definitely had enough for now. Hasn't she done a good job?”

The class applauded a little.

“And thank you to all my brave volunteers,” Cadance said with a nod to the still-sleeping Shining Armor and a wink to Scootaloo.

The class applauded a little more, but it quickly died down.

“Now, since our volunteers are exhausted and we've demonstrated more or less everything you need to know about sexual anatomies and how they work, how about we move on to today's homework?”
