“... and with that, we’ll conclude our lesson on the downfall of the Seapony Empire for the day.” Cheerilee looked up from the well-worn pages of her teacher’s edition history book and grinned at the sight of her students racing to stuff their own textbooks into their bags. It was Friday afternoon after all, which meant that the only thing standing between them and two and a half days of freedom was her verbal dismissal of the class. “But...” the schoolmare continued, eliciting a mass groan from her students. “Now, now, this will only take a moment, everypony,” Cheerilee assured with a dismissive wave of her hoof. “Before I release you from class, I’d like to take a moment to go over the test results of Wednesday's unit on pony sexual reproduction with you.”
A simultaneous shudder swept through the class as they collectively recalled the graphic nature of the excruciatinglydetailed documentary on equine reproduction Cheerilee had subjected them to only two days ago. The majority of the class—save for a select two oddities by the names Snips and Snails— had been permanently scarred by the psychological torture their teacher had written off as a mandatory part of the curriculum.
“Now, I know it wasn’t exactly easy for you to take it all in—”
Cheerilee stopped herself short as she heard Snips and Snails chuckling amongst themselves. “Take it all in, huh? I’ll bet she could,” Snips whispered to his lankier, and decidedly more oafish, classmate.
“Dohoho, I see what you did there,” Snails drawled with a dopey grin plastered across his face.
Cheerilee could feel her face grow hot with embarrassment at the comment. In her flustered state, the schoolmare hastily stammered for wording that wouldn’t be taken so easily out of context. “I-I meant, to learn the module!”
“I’ve got a module she can learn, if you know what I mean, eh?” Snails whispered, playfully nudging his much stockier counterpart.
“Snails, that didn’t even make sense.”
Cheerilee rolled her eyes at the colts before turning her attention back to the matter-at-hoof. “But, nonetheless, I’m very proud of you all for bearing with it. Even though it was a very long and hard unit, you’ve demonstrated that you have a firm grip on the—”
Cheerilee found herself once again interrupted by another bout of snickering from the resident goons of her class. “Heh, I’ve got a long, hard unit that could use a firm grip, if you catch my drift,” Snips chuckled, Snails chortling in a moment later.
Cheerilee held her composure and fought the urge to slam her face into her desk. “...I’ll just read off the grades so you all can go, how’s that sound?” Cheerilee said flatly.
A collective “Yay!” resonated from the rest of the class as the irritated teacher swept away a fair amount of clutter from her desk to reveal a small stack of papers bound together by a paperclip.
“Twist, with the highest grade in the class: one-hundred percent. Very good, Twist!”
“Thath thooper! I can’t wait to sthow my parenth!” the filly gushed.
Cheerilee beamed at the heavily-lisped filly before turning to address the second of her filly prodigies. “Silver Spoon, with the third highest grade in the class: ninety-seven.”
Silver Spoon confidently pushed her glasses up the bridge of her nose before scoffing and letting loose with a bout of self-assured rhetoric. “Like, did you expect any less?”
“Applebloom, Sweetie Belle, Scootaloo: eighty-one, ninety-two, and seventy-three respectively. Great work, girls.”
“See, Scootaloo, I told you that you should’ve studied with us instead of drawing,” said Sweetie Belle.
“Yeah, yeah, whatever... a ‘C’ is still passing isn’t it?” Scootaloo asked.
“Pffft, that’s hardly passin’, Scoots,” Applebloom replied.
“Oh, what do you know?” Scootaloo growled, while her friends proceeded to giggle and muss up the mane of the grumbling pegasus.
“Snips and Snails, both of you just managed to pass with an... ugh...” The schoolmare rolled her eyes as she prepared for the obvious innuendo that would ensue. “Sixty-nine,” she concluded flatly.
“Hey, Snails, she said sixty-nine!” Snips doubled over and fell out of his seat laughing uncontrollably.
“Gahaha— wait...” Snails took a moment to mull his friend’s joke around in the cavernous space where one would normally expect to find a brain, before he finally arrived at the conclusion he often reached while pursuing any form of higher thought: “I don’t get it.”
“And lastly, Diamond Tiara...” Cheerilee looked at the test paper in front of her, then at the filly in question, and frowned as she returned her attention back to the offending document. “I’m afraid I’m going to have to ask you stay after class. Pipsqueak, I’d like to see you after class as well.”
“Oh, bollocks,” said Pipsqueak. “Me mum isn’t going to be too happy about this...”
“What!?” Diamond Tiara whinnied. “But I have things to do this afternoon! Why do I have to stay back?”
“I’ll explain after the rest of the class leaves, Diamond Tiara,” Cheerilee said sternly.
“Hey, Diamond,” Silver Spoon started. “I’ll wait for you outside if you want.”
“No, you go on, Silver Spoon. I’ll see you this weekend,” said Diamond Tiara.
“The rest of you are dismissed, so I’ll see you in class Monday, my little ponies!”
Not five seconds after Cheerilee had given her consent, the classroom had emptied out faster than the bladder of a certain yellow pegasus during the great dragon migration, and the rampaging students racing towards freedom had left a literal dust cloud in their wake. Once the dust had settled, the only inhabitants left in the room were Pipsqueak, a sulking Diamond Tiara, and Cheerilee herself. The schoolmare hummed to herself as she sifted and sorted through a small stack of papers on her desk. Upon finishing her nitpicking, Cheerilee finally turned her attention to the two she had requested to stay back. “Pipsqueak,” she called.
“Yes, Ms. Cheerilee?” the pinto colt replied.
“I’d like to talk to Diamond Tiara first, so could you please wait outside until we’re through in here?”
“Yes, ma’am.” The colt heaved a sigh of relief as he trotted to the door and slipped outside. His sentence had thankfully been postponed for at least few more moments.
After Pipsqueak left, it was just Cheerilee, Diamond Tiara, and an awkward silence that lingered as the teacher prepared to improvise a lecture. “Diamond Tiara,” she started.
The brooding filly gave only the slightest tilt of her head in response to her teacher’s words.
“Do you know why I’ve asked you to stay after class?” Cheerilee asked.
“No, Ms. Cheerilee,” Diamond Tiara said sardonically, still avoiding eye contact with her teacher.
“Would you like to guess?”
“Because I failed another dumb test?” Diamond Tiara spat before turning away completely, forelegs crossed.
With a sigh, Cheerilee shook her head. It was never easy dealing with a problem child, but where difficulty failed to entice, the moral reward of helping one of her beloved students was more than enough to send the teacher through the motions. Cheerilee stepped from behind her desk and trotted over to the pink earth pony. “Well, that’s part of the reason, Diamond.” Cheerilee placed a hoof on the pink pony’s shoulder, but quickly found it shirked off as an angry Diamond Tiara shifted away.
“So, what’s the rest of the reason?” Diamond Tiara asked, intent on keeping her teacher on the most frigid patch of her cold shoulder treatment.
“I’d like to answer your question with another question, Diamond Tiara,” said Cheerilee.
Diamond Tiara raised an eyebrow at her teacher’s words, but remained as distant as she could.
“Do you think the material I teach in class is too hard, Diamond?”
“Well... no...”
“Answer me honestly, Diamond,” Cheerilee instructed.
“I don’t think it’s hard, Ms. Cheerilee, it’s just...”
“It’s just what?” Cheerilee pressed.
“I don’t know, I just don’t get it!” Diamond Tiara bellowed.
“Well, I’ve talked to your father about your performance in class and some of the behavior you’ve exhibited towards—”
Diamond Tiara, feeling indignant and betrayed by her teacher, began to shake and shiver out of frustration. “You... you told my daddy about—”
Cheerilee simply held up a hoof to silence the simmering filly. Much to her surprise, Diamond Tiara merely grit her teeth and remained silent. “Yes I did, and both Mr. Filth— I mean Mr. Rich and I came to an agreement.”
Diamond Tiara kept her jaw clenched, but cooled down a bit at the mention of her father’s name.
“We both think that if you were to see a tutor a few days out of the week, it would greatly benefit your performance in class.”
“A... tutor?” Diamond Tiara asked, grimacing slightly at the word as it rolled off of her tongue.
“That’s right, Diamond Tiara, a tutor. Just one or two days out of the week to help get you up to snuff in class, and also to give you make-up assignments that I’ll use to excuse some of your less-than-satisfactory grades. But only if you want to, Diamond. I don’t want to force you to do anything you don’t want to, but I can’t help you unless you let me.”
Diamond Tiara mulled the prospect around in her head for a moment. On one hoof, she knew that if she didn’t start getting proactive about her grades, her father would most likely send her back to a private school somewhere far away and she’d probably never get to see her Ponyville friends again. But on the other hoof, the filly had seen many tutors in the past, all of whom boasted about remarkable educational backgrounds and scholarly achievements, none of whom had been able to make any significant progress with the filly. As far as she was concerned, the whole idea was bound to fail. However, Cheerilee had gone as far as speaking with her father about the whole situation, and Diamond Tiara knew better than to go against his judgement. With a defeated sigh, Diamond Tiara turned to her teacher and finally ceded. “Alright, Ms. Cheerilee. If my dad thinks it’s for the best, then I’ll go. I just don’t see what good it’ll do…” she grumbled.
Cheerilee beamed at the crestfallen filly and made another attempt to lay a reassuring hoof on her student’s shoulder. She was pleasantly surprised to find that Diamond Tiara allowed her to maintain the contact instead of just pushing her away. “Hey, if it counts for anything, I think you’ll do just fine, Diamond.”
The filly wordlessly nodded in response to her teacher’s encouragement.
“Now then,” Cheerilee began trotting back to her desk. “Your first tutoring session will be this afternoon, at the Ponyville Library, and you’ll be retaking the sex-ed module from Wednesday.”
“This afternoon? But I had plans and—“ Diamond Tiara looked into the less-than-impressed eyes of her teacher, and crumbled beneath the educator’s unspoken pressure. “Yes, Ms. Cheerilee.”
“Oh, don’t fret about it too much, Diamond. I’m sure that you’ll really like the mare overseeing your studies. After all, she seemed especially excited and literally jumped at the opportunity to teach you!”
Diamond Tiara cocked an eyebrow at the fuschia mare’s description. “Who is it?”
“Twilight Sparkle. And if I know her, she won’t stop until you can recite entire textbooks from memory. Now go on, Diamond Tiara, Ms. Sparkle is the last pony you want to keep waiting, so I suggest you get there nice and early. Oh, and could you send Pipsqueak in after you leave?” Cheerilee asked as she pulled a pair of rimless reading glasses from a drawer in her desk and pushed them up on the bridge of her nose.
Diamond Tiara nodded to her teacher, gathered her belongings, and stuffed them into her pink, rhinestone-encrusted saddlebags before trudging to the door. The filly placed her hoof on the knob, yet she didn’t turn it. She couldn’t turn it, at least, not without first regaining her air of smugness and superiority first. After taking a deep breath to regain her composure and character, Diamond Tiara pulled down the door handle and stepped outside for the first time since recess had ended. She didn’t have to look long before she spotted Pipsqueak, who was steadily drawing in a nearby patch of dirt with a stick. “Hey, dweeb,” she spat.
“Yes, Ms. Tiara?” Pipsqueak responded, nervously trotting over to the prissy filly.
“Okay, ew.” Diamond Tiara held out a hoof to the dirt-covered colt, effectively halting him at a distance she found to be suitable. “First, personal space. You’re like, covered in dirt. Second, you’ll never call me ‘Ms.’ again if you know what’s good for you. Lastly, Ms. Cheerilee said she’s ready to see you now, and let’s just say I wouldn’t want to be in your horseshoes,” Diamond Tiara teased.
“Wh-what do you mean?” Pipsqueak asked nervously. “Is she upset with me? Did I do something wrong?”
Diamond Tiara smirked at the beguiled colt, satisfied that he had fallen for her little ruse hook, line, and sinker. “Oh, you’ll see...” She snickered as she trotted down the dirt road to Ponyville proper, leaving a panicked Pipsqueak behind her.
“I don’t think I care for her much...” The cockney colt mumbled under his breath while turning towards the door. Pipsqueak placed a hoof to the door’s frame and pushed it open just enough to peek inside. There, he spotted Cheerilee sorting through a stack of papers on her desk, her face a mask of stoic focus given even more intensity by the glasses she had donned only moments ago.
“Come inside, Pipsqueak,” she called automatically, not even bothering to look up from her desk.
“Y-yes ma’am,” he stuttered while stumbling forward, taking care to close the door behind himself.
“Do you know why I’ve asked you to stay after class today?” Cheerilee asked, her attention still heavily geared towards her gradebook.
Pipsqueak swallowed back a nervous lump that had formed in his throat during the short trek towards his teacher’s desk. “N-no, Ms. Cheerilee, I haven’t the faintest idea.”
With a sigh, Cheerilee flipped the notebook closed, grabbed a single sheet of paper off of her desk with her mouth, and trotted to the front of her desk. Wordlessly, she dropped the paper, allowing it to gently float to the colt’s hooves.
Pipsqueak cast his timid gaze down at the paper, half expecting to see a massive zero adorning the page or even a letter of expulsion issued to him for some infraction he was wholly unaware of. Much to his surprise, it was his only sexual reproduction test sporting a massive ninety eight percent circled in red ink. “But... I... Ms. Cheerilee, I don’t get it.”
“Get what, my little pony?” Cheerilee asked.
“Aren’t you... upset with me?”
“Upset with you?” Cheerilee chuckled. “No, no, no, I’m not upset. Where did you get that idea?”
“Well, Diamond Tiara said that—”
“Celestia, that girl is incorrigible..." Cheerilee giggled, and shook her head. “I think she was just having a little fun at your expense, Pipsqueak.”
The colt heaved a sigh of relief, but quickly found his reprieve from nervousness short-lived.
“However, I did want to speak with you about some of your answers on that test.”
“I didn’t cheat, I swear it!”
“And I didn’t say that you did, Pip.”
“Oh.”
“I just wanted to discuss some of them with you; namely your responses to the essay questions.”
“Oh....okay?”
“I have to say, I was very impressed by your knowledge of female anatomy, but that got me thinking...” Cheerilee smirked, and turned her back to Pipsqueak, her tail swaying playfully back and forth all the while. “You seem to know a lot about mares, but have you ever—” Cheerilee swept the contents of her desk to the floor, and crawled onto the now barren table.“—known a mare?” She asked rhetorically, running a hoof along her voluptuous curves.
“M-M-Ms. Cheerilee?”
With her free hoof, Cheerilee slid her reading glasses off of her delicate features, and nibbled the temple-tip suggestively. “It’s alright, Pipsqueak, come a little closer. I don’t bite... much.” the older mare cooed, ushering the wide-eyed colt closer with a wave of her hoof.
Dry mouthed, timid, but above all mesmerized, Pipsqueak hesitantly trotted forward to meet his teacher’s amorous invitation. Needless to say, by the time they reached the end of their “supplementary lessons”, Cheerilee and Pipsqueak would have single-hoofedly given a new meaning to the phrase “after school special”.
After twenty minutes of walking with the heat of the mid-spring sun beating down on her neck, Diamond Tiara arrived in the market of Ponyville proper, parched and panting. The trip—as always—had taken far too long for the spoiled filly’s liking, and it didn’t help that since she tended to avoid the outdoors like the plague, her poorly acclimated body decided that a profuse stream of sweat was the best means of dealing with the heat. Out of the corner of her eye, Diamond Tiara spotted a nearby lemonade stand. Almost reflexively, she reached into her saddlebags and procured a single bit from a pocket containing several of the small coins. While she couldn’t do anything about her uncomfortably sweaty coat, at the very least she could solve the issue of her terribly dry mouth.
She approached the stand, bit in mouth, and promptly dropped the coin on the counter. The gray-coated mare behind the counter swept the bit into a pouch on her apron without hesitation, and quickly replaced the bit with a tall, refreshing glass of juice. Diamond Tiara seized the glass as swiftly as the mare had put it down and greedily sucked down its contents. As the salty, unpleasant beverage slid down her throat, Diamond Tiara immediately gagged and spat up the brackish yellow drink. “Gah! What the hay?” Diamond Tiara slammed the glass back on the counter, glaring at the gently beaming mare who had sold her such an atrocity. “You call this lemonade?”
“Nope! Corn!” The mare responded, her mouth wide open in a toothy grin.
“Wh— I don’t even— are you blind?” Diamond Tiara indignantly slammed her hooves on the counter, and pointed at the large lemon-shaped sign hanging behind the blond-maned mare. “Your sign clearly says—” The pink filly stopped herself as she took a good long look at the actual wording on the sign. “—mashed corn.” She finished flatly. With grit teeth and a livid temperament, Diamond Tiara stomped away from the juice stand in search of the library.
However, halfway through the market it dawned on the frustrated filly that she hadn’t even the faintest idea of where the library was. She had been there a grand total of two occasions in the last five months, and even then she had been following Silver Spoon. Diamond Tiara continued to aimlessly wander down the market road, trying her hardest to recall any of her steps from the last time she had visited. All that she could remember of the building was that it was constructed inside of an old tree and that it was located fairly close to Sugarcube Corner. Aside from that, she knew nothing of the building’s whereabouts.
Just as she was about to give up her search, Diamond Tiara heard a familiar trio of giggles coming from her left. Turning to face the source of the sound, she was less than pleased to find the noise originating from none other than the Cutie Mark Crusaders. At the sight of the three blank-flanked fillies, Diamond Tiara’s mouth reflexively opened in preparation to lambaste them for not having found their special talents like the majority of their peers. “Hey blan—” However, before she could let loose with one utterance of her tried-and-true taunt, she stopped herself short, as it had occurred to her that they could probably point her in the right direction. “—I mean, Applebloom!”
“Yes?” Applebloom turned to face the source of the voice, yet as she caught sight of the familiar light-pink pony approaching, her smile practically evaporated. “Oh, it’s just you.”
“What do you want?” Scootaloo sneered.
“Come on girls, maybe we should just go search for our cutie marks somewhere else,” Sweetie Belle suggested, pushing her friends away with surprising strength.
“Wait, wait! Don’t go, I need your help!” Diamond Tiara pleaded.
Applebloom almost laughed out loud at the absurdity of their usual tormentor’s request. “Lemme get this straight: you need our help?”
“And why should we help you? It’s not like you’ve ever done anything but give us grief.” Scootaloo growled.
“Look, I just need directions to the library, okay?” Diamond Tiara admitted. Where the callus pony had been expecting some snarky retort, she was instead met with a trifecta of incredibly confused gazes. “Hey, what’s with those faces? You got a problem with me going to the library or something?”
“Well, no, it’s just that the library is right in front of you.” Sweetie Belle pointed behind herself to a large wooden sign bearing an imprint of a book.
“Gah! I, uh... I knew that! Geez, do you think I’m stupid or something?”
Applebloom raised an eyebrow at their bully’s unusual choice of words. “We didn’t say you were. Is everythin’ alright, Diamond Tiara?”
“Hmph, just mind your own business, blank-flank,” Diamond Tiara huffed as she trotted off with her nose in the air.
“Sheesh, what’s her problem?” Scootaloo scowled after the prissy pink pain-in-the-flank as she trotted towards the tree.
“Who cares? Let’s just go somewhere else before the other one shows up too,” Sweetie Belle said.
Diamond Tiara glanced over her shoulder and waited for the three fillies to trot away before pushing her way through the heavy, wooden door.
The first thing to hit Diamond Tiara about the library was how abnormally quiet it was, given how many ponies were presently inhabiting the modestly-sized building. Even Snips and Snails could barely be heard chuckling to themselves as they flipped through the more explicit pages of an old anatomy textbook.
“Hi, there!” The pink filly turned to face the warm voice emanating from behind her, where she was met by the grinning face of the library’s lavender-coated caretaker. “You must be Diamond Tiara, I’m Twilight Sparkle.” The unicorn held out her hoof in a polite greeting, which Diamond Tiara hesitantly accepted. “Ms. Cheerilee told me you’d be coming by today, so I’ve been brushing up on my pony reproduction notes.”
Diamond Tiara grimaced at the thought of having to review that horrible unit for a second time, but it couldn’t be helped. She had already come this far.
“Come on, Diamond, we’ll study upstairs so we don’t interrupt anypony down here.” Twilight gently nudged the filly on the rump with her nose, to which Diamond Tiara scoffed and shot the older mare a short-lived look of disbelief, before she was forced into walking again. The two walked up the stairs to Twilight’s room in silence, Twilight mentally reviewing the lesson plan she had crafted and burned into her memory, Diamond Tiara moping over her lost afternoon.
A moment later, the short climb deposited the pair into a room that was absolutely cluttered with several oddly symmetrical stacks of books and bore only a hint of a living area. “This is where you live?” Diamond Tiara asked, her voice laced with more of a derisive tone than she intended to project.
“Heh, heh, yeah...” Twilight sheepishly rubbed the back of her head and chuckled to herself. “I know it’s bit messy at the moment, but it shouldn’t interfere with your less— look out!”
Time seemed to slow down for Diamond Tiara as she watched one of the towering piles of reference books topple over, threatening to crush her. Instinctively, she clenched her eyes shut and braced her body for the ensuing impact of the tomes. A second passed. Then two more followed the suit of the first, yet no harm befell her. Puzzled, Diamond Tiara opened her eyes, only to be awed by the sight of the books hanging in mid-air, each one surrounded by a vibrant purple aura. Diamond Tiara hastily scurried out from beneath the mass of floating books, which clattered to the ground almost immediately after.
“Spike, you need to be more careful! You almost crushed my pupil!” Twilight shouted at someone hidden away by the clutter.
Curious, and in the mood to chastise whoever had nearly flattened her, Diamond Tiara looked about the labyrinth of a room, scanning for any trace of this ‘Spike’ character, but saw no one. The room was empty, save for the two ponies and an utter mess of written knowledge. It took her by surprise when a strange reptilian creature emerged from beneath the toppled-over pile of books. It took the filly a moment to recognize the creature as an actual dragon, and a second longer to register the fact that she was within spitting distance of it. She had heard that there was a dragon somewhere in Ponyville, but had never made the effort to find out exactly where. Regardless, the creature’s appearance was a little more than off putting for the filly.
“Sorry about that, Twilight...” the dragon moaned, rubbing his head where one of the weightier volumes had struck him. “It’s just that I—” Spike’s sentence cut off as his attention was drawn towards the flamboyant pink coat of his anxious guest. “Hey! I haven’t seen you around here before. My name’s Spike, what’s yours?” The dragon extended a claw in greeting to Diamond Tiara, who in turn shied away from the appendage as though it were on fire. “Geez, what’s her deal?”
“Don’t feel too bad, Spike.” Twilight rested a hoof on the dragon’s shoulder. “She’s probably just nervous because she’s never seen you before: dragons aren’t exactly commonplace in Ponyville, you know.”
“Hmph, well, that’s still no way to react...”
“Look, Spike, I’ll let you and Diamond Tiara get acquainted later, but for now, do you think you could go downstairs and watch the library for me while I get started with her lessons?”
Spike huffed and rolled his eyes. “Yeah, yeah...” The dragon marched, grumbling, down the stairs to fulfill his mistress’ request.
“Alright then,” said Twilight. “My desk should be—” The unicorn’s horn lit up with a vibrant, shivering aura that spread to a select few stacks of books. With a small mental push, the towers of tomes slid apart, revealing a small, rather plain desk containing only a few quills and parchments. “—right there. Why don’t you take a seat so we can get started?”
“Yes, Ms. Sparkle,” Diamond Tiara sighed. From her past experiences with tutors, she already had a fair idea of how this first—and most likely only—session would go. First, Twilight would probably start out with an overview of the material, which would be followed by some clichéd pep-speech, and lastly, a lesson plan that was doomed to fail right off the bat. At best, she gave it a modest hour, two at the most, before Twilight ultimately called the situation a lost cause and disowned the filly as a pupil.
“Okay, Diamond Tiara,” Twilight summoned a particularly thick book from a nearby stack titled: Perusably Practical Pony Physiology: A Paperback Primer, Part One of Plenty, and began flipping through the pages of the tome, seemingly at random. “I know Ms. Cheerilee said you were having trouble memorizing and identifying the key points, so before we start, let’s see how much you retained from her class. Hmmm...” The unicorn tapped a hoof to her chin pensively as she sifted through her bloated mind for an appropriate question to gauge her student’s understanding. “Ah, okay, here’s a good question: what is the hormone in stallions primarily responsible for the growth and development of reproductive organs?”
“Ummm... I think it’s... uhh...” Diamond Tiara wracked her brain for any residual trace of the answer in her memory, but found that the name had escaped her completely. “I don’t know,” she finally admitted.
“It’s testosterone.”
“I’m sorry, Ms. Sparkle,” Diamond Tiara apologized half-heartedly.
“No, it’s alright, that question was a little hard anyway. Here’s an easier one for you: what fluid generated by males has to interact with the female ovary to enable the fertilization process?”
“Err... I...”
“You don’t have to get it exactly right, just guess.”
Diamond Tiara mulled the question over for a moment before arriving at the same conclusion as the previous question. “Ms. Sparkle, I... I just don’t know, alright?”
Twilight rubbed her temple with a hoof as she contemplated the best approach to this situation. “Okay, well, why don’t you tell me what you do know about the reproductive process, and we’ll take it from there?”
“Well... I know that it takes both a stallion and mare to make a foal, but that’s about it.”
The librarian shrugged and sighed quite deeply. “We’re going to have to start from the beginning then, aren’t we?” Teaching Diamond Tiara was going to take a lot more work than she had anticipated, but come Tartarus or high water, she was going to make sure that this filly knew how the equine reproductive system functioned. In excruciating detail. “Well, that’s no problem at all. I prepared my lesson plans from the ground up in the first place, so working with a blank slate is perfect for me.” Twilight rested her hoof on the dejected filly’s shoulder. “Don’t worry. By the time I’m through with you, you’ll be able recite each section verbatim, in song no less!” she joked.
Diamond Tiara swallowed and managed a weak grin at her tutor’s optimism, but then again, they were always optimistic at first. For the time being, the best she could do was put her best hoof forward and give Twilight the benefit of the doubt, as well as her undivided attention.
“Well then, let’s start with the basics. You already know that it takes a mare and a stallion to conceive a foal, right?”
Diamond Tiara simply nodded and waited for Twilight to continue.
“Well, why do you think that is?”
“Because of their, you know... different... things.”
Twilight raised an eyebrow at the filly’s hesitant tone. “Care to elaborate a little more for me?”
“You know, their... stuff,” Diamond Tiara mumbled, fumbling her forelegs uncomfortably.
“Hormones and gential development,” Twilight answered for the filly. The unicorn gently dropped the book in front of her pupil, and pointed to a highlighted passage for Diamond Tiara to follow along with as she continued to speak. “You see, there are two major hormones that are necessary for the development of stallions and mares: testosterone and estrogen, respectively. However, this does not mean that these hormones are gender exclusive, as stallions do possess some estrogen necessary for their development, albeit a significantly lesser amount, and vice-versa for mares. Now then, as to how blah blah blah gentials blah blah creation of ova, and production of seminal fluid blah blah...”
As Twilight droned on, Diamond Tiara found her ability to focus on the unicorn’s words slowly draining away and her thoughts drifting towards decidedly more trivial matters, such as what Silver Spoon was doing at the moment, or what she would wear to her father’s upcoming garden party this weekend in case any cute colts were to show up. Every so often, she would remember where she was and tune Twilight in for only the briefest of moments, but it was always a fleeting effort as a torrent of unrelated subjects would overload her already short attention span, and ultimately drag her back into a cesspool of obscure thoughts. After a certain point, Diamond Tiara’s mind was so mentally taxed trying to keep her hearing actively focused on Twilight’s voice that she eventually nodded off.
“... and after some very rigorous exertion on the male’s behalf, his autonomic nervous system will eventually reward his efforts by sending him through the process of ejaculation, through which a stallion releases semen that will fuse with an ova, or egg, and creates what is referred to as a zygote. Now this is where it gets interesting in my opinion, a zygote... Diamond Tiara?” Twilight glanced at the lightly dozing filly in question. “Are you paying attention?”
“Oh!” Diamond Tiara jolted upright, wiping a small trail of drool from her chin as she went. “Uh, yes of course, Ms. Sparkle.”
Twilight cocked an unimpressed eyebrow at the jittery display. “Really? Then what was the last thing I said?”
“Something about goats?”
Twilight shook her head in disappointment. She had just stood and belted out a university-quality lecture for a solid half hour and the filly before her hadn’t gained even an inkling of knowledge from the exchange. It was a mite difficult for the unicorn to accept that she had essentially just wasted her breath, but Twilight Sparkle, ever the optimist, wasn’t discouraged in the slightest.
“Alright, so you couldn’t follow the lecture. Well, it’s no big deal; I figured that it might be a bit too dry for a filly anyway, which is why I prepared...” as she spoke, Twilight’s horn began to glow with magical energy that the unicorn released in a purple cloud of smoke and light. As the mist cleared, an ancient slide projector perched atop an even more decrepit stand came into view. “...a slideshow! Doesn’t that sound like fun?”
It was Diamond Tiara’s turn raise an eyebrow at what would generally be considered misplaced enthusiasm. “Fun? If you say so...”
“Great! Just let me turn it on.” Twilight flicked a black switch on the apparatus, and two seconds later the old projector sputtered to life, casting horribly unfocused images upon a nearby wall. “Hmmm...” Twilight stepped in front of the projector beam and seized a focus knob on the side of the machine, experimentally fumbling about with it. “Just need to make a few adjustments to the focus... and... perfect!” Twilight pulled away from the projector, allowing the diagram-bearing light to spill forth onto the wall.
Diamond Tiara grimaced as intimately-detailed depictions of pony genatalia slowly came into focus on the wall; it was starting to look like Wednesday all over again. The filly shivered at the very thought.
“Now all we need is a sheet...” Twilight telekinetically seized the blanket from Spike’s basket and affixed the bedding to the wall. “... and voila!” Satisfied with the projector settings, Twilight levitated a nearby pointing stick from a shelf on the stand and trotted up to the projection sheet. “Now we can begin... again.”
Diamond Tiara rolled her eyes, a gesture which went unnoticed by her tutor, as Twilight had already delved back into the teaching mindset.
“Now then, we’ll start here.” Twilight maneuvered the pointing stick to the portion of the diagram displaying the male sex organs. “Of all of the components that comprise the male reproductive system, the most vital to the process of conception are the testicles.” Twilight’s horn flared for a moment, and an audible click could be heard from the projector as it switched slides. “Now, the purpose of the testicles is to generate sperm cells which carry half of the chromosomes needed to create and determine the gender of the zygote, and the average male has two of them. The reason for this is that developmentally, ponies are bilaterally symmetrical. Why, even females have two sets of blah blah blah for this same blah blah...”
Diamond Tiara yawned as she found her attention drifting away from the section of the diagram Twilight was elaborating on, and more towards one of the generalized pictures of the appendage in question. It looked like an egg, which reminded Diamond Tiara that she hadn’t eaten anything since lunch. Diamond Tiara propped her head on her hoof as she was enveloped by a torrent of food-related thoughts.
Lunch. Today’s lunch had been as bland as ever. That school menu needed to be adjusted for the sake of variety, as all of the meals were starting to run together in the filly’s mind. After all, Cheerilee had served gray mush with peas and bread yesterday, and this afternoon was orange mush with... something. Something that Diamond Tiara couldn’t quite identify. The point was that it was all just mush, and tasteless mush at that. Would it have hurt the teacher to buy some sweets from Sugarcube Corner?
Sweets. Sugarcube Corner. She caught herself thinking about various sweets from the bakery, and how she would have given her left hind-leg for one of that mentally-touched pink mare’s specialty cupcakes instead of sitting through this totally boring slideshow.
Slideshow. She was supposed to be paying attention to the slideshow in front of her wasn’t she? Diamond Tiara glanced up at her tutor who was still jabbering on about the module. The unicorn looked a little giddy even. It was probably some part of the module that she must have found really interesting. Diamond Tiara sat up straight, perking her ears up so that she might be able to catch the gist of what her tutor was trying to teach.
“...and I think that just about covers everything!” She heard Twilight conclude.
“Wait, that was the entire reproduction module?” Diamond Tiara asked in sheer disbelief.
“Yes it was!” Twilight chirped. “I’ll admit, I’m surprised that it only took us forty minutes to cover all of that material, but we did it!”
“Forty minutes? That was forty minutes?” Diamond Tiara choked out.
“That’s what I said. I mean, I didn’t believe it either, but when I looked at that clock, sure enough an entire forty minutes had just passed me by. I guess time really does fly when you’re having fun!” The unicorn chuckled and gave herself a pat on the back for a job well done. “So, Diamond, what part did you find the most interesting?”
Diamond Tiara returned Twilight’s question with an awkwardly placid silence. The filly was still having difficulty believing that she had just sat through a forty minute presentation, and gained absolutely nothing from it. A feeling that, in a few short moments, would be mutually understood by the teaching party.
“Diamond Tiara?” Twilight called.
“Oh, right, my favorite part... it was... ummm...”
“You weren’t paying attention were you?” Twilight asked quite bluntly.
“Well I...” Diamond Tiara started, but stopped herself short. “I’m sorry, it was just... I just couldn’t follow it.” The tension in the air soon became too much for the purple-maned filly, forcing her to meekly glance up at her tutor, who was absolutely beside herself and looked as though she might just explode.
The red-faced unicorn was ready to assail her frustrations towards the filly with such force and volume that mothers in Canterlot would clasp hooves over the ears of their children until the unicorn’s worrisomely-worded wrath subsided. Yet, Twilight managed to hold her composure and hide her frustrations behind a poorly-crafted mask of feigned patience that was betrayed only by her visibly grinding teeth. “Look,” Twilight rubbed her temples in as soothing a manner as her agitated state would allow her. “Why don’t you go downstairs and take a break, Diamond. When you come back, we’ll try it again, alright?”
“But, I—”
“Please, Diamond. I just need a few minutes to gather my thoughts, all right?”
“Yes, Ms. Sparkle.” The downcast filly trudged to the staircase, her head lowered in a mixture of shame and irritation. After all, it wasn’t like she wanted to come here anyway.
Twilight waited until Diamond Tiara’s hoofsteps disappeared down the staircase before heaving out a groan heavy with pent-up frustration from the past hour. “This is impossible! I spent an hour lecturing her, and I’ve got nothing to show for it? How could she have not learned anything?” Twilight seized a nearby pillow which she buried her face into before screaming her lungs out.
“I didn’t want to believe Cheerilee was right, but for Celestia’s sake, a whole hour? An entire hour and she couldn’t tell me anything about the material! It’s not like I was asking her for transmutation theorems or a research paper on the anti-life equation, it was just pony reproduction!” The frustrated mare leapt off of her bed, carefully navigating the stacks of reading material cluttering her room until she reached the window. She took a sweeping view of Ponyville, her gaze eventually settling on Canterlot in the faraway mountains. Twilight thought back to her lessons under Celestia, and how quickly she advanced compared to the other students around her. She eventually remembered her contemporaries coming to her for help. She never really stopped teaching, if she thought about it. Every day she taught somepony a new lesson, even if it was herself. “If I can raise a baby dragon from an egg and explain to Scootaloo why it’s impossible for the library welcome mat to be covering a pit of quicksand, then I shouldn’t have any problems teaching a foal, right?”
“...right?” With a sigh, Twilight sank to her haunches, leaning her back against a nearby bookshelf. Completely absorbed with contemplating her next plan of attack, she failed to notice that there was a book teetering dangerously over the edge of a shelf just above her head.
“Ow... hey, what’s this?” Twilight scooped the book up from it’s resting place on her hip, and held it up for scrutinization. “The Egghead’s Guide to Teaching by Deus ex Machina? I don’t remember seeing this book before, but I guess it’s worth a look.” Twilight flipped the reference guide open, making sure to skip the table of contents as the book only looked to be about a few hundred pages long. If nothing else, it would at least serve to calm her nerves and focus her thoughts.
‘Most education experts support the learning categorization theory of the VAK/VARK education module, which states that there are three to four different primary methods from which a pony can derive information. There is the visual method of learning, through which the individual derives information via imagery and pictures, the aural method, through which one can absorb lessons and instructions from lectures, speeches, or any other audio-based mediums, and lastly there is the kinesthetic method, through which one retains knowledge by immersing themselves into the subject matter with hooves-on experience and physical activities. Various studies have shown some individuals are proficient in the use of two or all of the aforementioned learning methods, while others specialize, and potentially depend on, one style for their learning needs. Some professionals believe that there may be a fourth method based around the concept of learning through reading and writing, but it has been argued—”
“Wait a minute.” Twilight shifted her attention to the section on kinesthetic learning and the portion that followed. The unicorn thoughtfully tapped a hoof to her chin as she thought back to Diamond Tiara’s issues with retaining the subject matter when something dawned on her.
“Maybe it isn’t Diamond’s fault...” she mused under her breath. “Maybe I just wasn’t being attentive to her needs!” Twilight sprang to her hooves and began tearing through her book shelves, levitating and dropping tomes left and right as she searched for something that would help her construct a lesson plan around Diamond Tiara’s unique learning requirements. “This whole time I’ve been trying to teach her the way that I learn, when what she needs is something to get her involved, something she can really wrap her hooves around, something—” Twilight stopped herself short and dragged a hoof down her face as she recalled just what it was that she was supposed to be teaching. “Oh Celestia.”
Unable to think of anything other than how she had completely and utterly let down yet another tutor, Diamond Tiara sulked her way down to the lower level of the library. The room had emptied out significantly since she’d first walked in, and that suited her just fine: she didn’t want anypony to see her in such a downtrodden state, lest she reveal her vulnerable side to anypony from her class. The last thing she needed was for the Cutie Mark Crusaders to have any dirt on her. As her hooves made contact with the ground floor, the filly looked around for a secluded spot so that she might pout in solitude. As luck would have it, she spotted a vacant alcove in a nearby window, complete with a body pillow, and wasted no time laying claim to the space. Just as she settled in, a familiar dragon stepped in front of her holding a tray of freshly-baked chocolate chip cookies.
“Hey, it’s you! Twilight finally let you have a break, huh?” Spike paused to pop one of the pastries into his maw. “Your name was Diamond Crown, right? Or was it Diamond Hat? It was Diamond something...”
“Tiara.” Diamond Tiara kept her gaze averted from the dragon, who had chosen to sit in the nook next to the filly.
“Right. Diamond Tiara, that was it. Man, I am so bad with names and new faces.” The dragon stopped to pop another cookie into his mouth before continuing. “So, how are the lessons going with Twilight?”
“...”
“Still not talking to me, huh? Are you still weirded out by me because I’m a dragon?”
“It’s not that, it’s just... I’d just rather not talk about it.”
“That bad, huh?” Spike offered his new acquaintance a cookie from the plate, which she hesitantly accepted with a weak smile.
“Mmhm.” Diamond Tiara nodded and took a nibble out of the cookie. As she chewed, she found herself easing up a little around the dragon; growing comfortable even. “It’s just that I’ve had a lot of tutors quit on me in the past, and—”
“Wait, wait, you’re afraid of Twilight giving up on you? Gwa, ha ha!”
“D-don’t you laugh at me, you jerk!” Diamond Tiara threw her cookie at the dragon with as much force as she could muster, causing it break harmlessly against his scales, before turning away from him with crossed forelegs. “I can’t believe you! First you offer me cookies, and then you laugh at my problems? What is wrong with you?!”
Spike paused to wipe tears from his eyes and chocolate from the spines atop his head between fits of giggles, an action that only prompted Diamond Tiara’s temper to flare even higher. “I’m sorry, I’m sorry. It’s just that Twilight never quits, no matter how hopeless the situation. Trust me, she won’t quit on you, no matter how bad or impossible things seem.”
“You really... think she won’t just quit on me?”
“I know she won’t.” Spike shot the filly an assuring smile, which she returned, albeit in a nervous fashion. “Now, why don’t you go back up there? I’m sure that Twilight is ready to give it another go already.”
Rising to her hooves, Diamond Tiara nodded to the dragon and trotted off to the staircase feeling a little more confident about her next session with Twilight. “I wonder what she’s got in mind this time,” she mused to herself as she pushed through the door to Twilight’s room.
Diamond Tiara strode into the upper room, only to find that it had changed drastically. The mountains of books that were previously cluttering the room had seemingly vanished into thin air, allowing the filly to easily pick out the room’s only other inhabitant curled on her bed with a book. “Ms. Sparkle?” Diamond Tiara called out to the unicorn.
“Oh! Uh...” Startled by the sudden interruption,Twilight enveloped the book in magic, and slid it beneath a nearby pillow on the bed. “Yes, Diamond?”
“Look, I’m... I’m sorry about earlier, but if you’ll let me, I’m ready to try again, and I promise I’ll pay attention this time. So, please teach me the reproduction unit again?”
Twilight beamed at the filly’s reformed attitude. Maybe there was hope for Diamond Tiara yet, especially considering what the unicorn had just discovered about her problematic student. “Diamond, why don’t you join me on the bed so we can discuss something?”
“Yes, ma’am.” As she made her way towards her tutor’s simple twin mattress bedding, the filly could hear the door shut behind her, but thought nothing of it as she crawled onto the cot and took a seat in front of Twilight. “So what did you want to talk about?”
Twilight turned to nudge the book she had been reading earlier even further under her pillow, returning her attention to the curious filly. “Well, while you were on break, I did some reading and I found something that might explain why you were having so much trouble paying attention to my lessons earlier.”
To this statement Diamond Tiara raised an eyebrow, but continued listening attentively.
“You see, from what I’ve read, I have reason to believe you might be what’s referred to as a ‘kinesthetic’ or ‘tactile learner’.”
“Tactile... learner?” Diamond Tiara repeated the easier of the two pronunciations, voice laden with uncertainty. “What does that mean? Is it bad?”
“Oh, no, not at all, my little pony. What it means is that the best way for you to learn things is if you do them by hoof, so to speak. Does that make sense to you?”
“Mmhm.” Diamond Tiara nodded. “But how will that help me learn the unit?”
Twilight averted her gaze from the filly and began to fidget her hooves uncomfortably as she cleared her throat. “Well... like I said, the best way for you to learn is through activities, but...”
“But what?”
“It’s just that there’s really only one thing that we could do on such short notice and it’s hardly appropriate... ”
“Well, what is it?” Diamond Tiara was growing weary of her tutor’s incessant beating around the bush, and her tone was beginning to reflect it.
“N-nevermind, it was a dumb idea anyway, you should just forget that I said anyth—”
“Ms. Sparkle,” Diamond Tiara interjected, her voice heavy with arrogant authority. “I gave up my entire afternoon to relearn this whole gross unit and I am not leaving until I do! So please, just tell me already!”
“So you’re really not going to leave, huh?” Twilight glanced into the determined eyes of her student, and silently cursed herself, wishing that she could take back the last three minutes of this conversation, but what was done was done. “I’ll tell you, but first,” Twilight reached out to rest her hoof on Diamond Tiara’s own. “I need you to know that some of what I’m about to teach, it’s not going to be anything like Ms. Cheerilee’s lesson plans. Are you okay with that?”
The pink filly nodded in response to Twilight’s question.
“All right,” Twilight sighed as she ceded to the filly’s insistence. Hesitantly, the unicorn stood up, but as she did, something else flopped down. From the moment she walked in, Diamond Tiara hadn’t paid any mind to the way that her tutor chose to lie down on the bed. In fact, no pony in their right mind would have paid such an obscure aspect any attention at all. To the average observer it would have seemed as though Twilight was just resting comfortably on her belly, and certainly not concealing an object that was absolutely vulgar in its nature; but alas, there it was, plain as a hydra in a hen-house.
Diamond Tiara gawked at the strange thing protruding from between her blushing tutor’s hind legs. “M-Ms. Sparkle, w-what is that thing? Where did it even come from?”
“Heh, right, that... well, you see, after I figured out that you were a kinesthetic learner, I started looking for ways to make reproduction interactive and... I... kinda found this spell.” Twilight rubbed the back of her head in embarrassment. “I was trying to do something about it when you walked in and, well you can see how far I got.” Twilight glanced up and took note of the awe-stricken expression on the filly’s face. “If this is too much for you, Diamond, then we can conclude the lesson right now...”
“Well, I...” Diamond Tiara was still surprised by the sheer presence the appendage commanded. Certainly she was intimidated by the thing, but she still had an obligation to fulfill to her teacher. “I suppose we can keep going with the lesson; you went through all of this trouble after all.” Diamond Tiara cast her full attention towards unicorn’s new accoutrement and felt the blood rush to her face, as she couldn’t quite take her eyes off of it for some reason. Looking at a diagram of a penis was one thing, and it was a very droll and uninteresting thing at that, but to see one up close was an entirely different matter. With a great deal of effort, she managed to avert her eyes just long enough to spit out a question. “But what are we supposed to do with... that?”
“Well, I suppose we could cover some basic anatomy with it for the time being.” Twilight sat down on her haunches, slowly spreading her hind legs so that the filly could get a solid and unhindered view of the member in question.
It was at this point that Diamond Tiara noticed something about Twilight’s equipment that was vastly different from what little she remembered of the earlier diagrams. “Ms. Sparkle, where are those two little things that are supposed to be right there?”
“Are you talking about the testicles?”
Diamond Tiara frowned slightly at the nomenclature, but nodded regardless.
“To be honest, the spell I found only gave me this part, so I really don’t know—”
“Can I... touch it?” Diamond Tiara asked apprehensively.
“Oh, um...” Twilight’s face flushed scarlet at the filly’s request. Admittedly, ever the empirically minded student that she was, Twilight simply couldn’t just allow the opportunity to explore the physical nature of the opposite sex to slip through her hoof. “I-I suppose so. I mean, it’s best for you to get some hooves-on experience after all, isn’t it?”
Diamond Tiara slowly trotted between her tutor’s splayed haunches, and quizzically tilted her head at the close-up view of the magically induced member. It was certainly much bigger up close, and from this proximity, she could see that it was of a disproportionate color palette, as a good portion of the black coloring greatly overpowered the few flesh-toned spots about it. Cautiously, she reached out and prodded the tip, to which its owner gave a slight shiver at as her brain registered the strange, but welcome, contact. “Huh, it feels all spongy and soft,” Diamond Tiara remarked as she continued to jab at it .
“That part is called the glans,” Twilight explained, wincing at each bout of contact from the filly’s hoof. With each contact, she could feel her penis growing firmer and more emboldened, and as a result the sensations only intensified. “From what I’ve read~ahn~it’s the most sensitive part of the~ohh~penis, because of the high~ahh~c-concentration of nerve endings,” Twilight managed to pant through the onslaught of sharp stimulation.
“So, then what about this part?” Diamond Tiara asked as she gave the slowly hardening shaft another curious, albeit much more concise, poke. The filly’s ministrations elicited another, much stronger shiver from the pony on the receiving end.
“This part?~Mmmn~ This part is the corpu—*pant*— corpus!” Diamond Tiara had taken the opportunity to change her approach to the anatomical exploration, and began to stroke it with both hooves.
Twilight could feel her hind legs beginning to quiver at the alien euphoria shooting through her spine and magically materialized member as the filly focused her efforts on rubbing the firmness of the shaft. However, the filly stopped and pulled away as she noticed a clear fluid leaking out of Twilight’s tip. “Hey, what’s this stuff?”
Twilight, now released, but still wanting, from the rapture of Diamond Tiara’s hooves, turned her attention to the transparent liquid emanating from her throbbing appendage. “Oh, that.” Twilight scratched her head as she sought a simplified explanation. “Well, I think that’s seminal fluid, or as it’s more commonly referred to, precum. And it’s blah blah blah...”
As Twilight, having forgotten her student’s learning preference, continued to ramble on about the discharge, Diamond Tiara leaned in and gave the running solution a hesitant sniff. “It smells weird...”
Diamond Tiara looked into the distant eyes of her rambling teacher, and shrugged. The unicorn had clearly gone off on yet another tangent, thus leaving the filly to her own devices.
“It’s dripping... I wonder...” Diamond Tiara leaned towards the cascading stream of pre-ejaculate, her tongue stiff and unyielding as she pressed it against the firm flesh of the lavender mare’s phallus. A sharp yelp followed by a fierce jolt erupted from the recipient of the lick almost instantaneously.
“D-D-Diamond, you can’t just~kyaaa~” Twilight’s words trailed off and her tongue lolled out of her mouth as her nerves were once again overloaded by the piercing heat of the filly’s small, edge-like tongue. Twilight nibbled on her lower lip as the filly continued to assault her senses with a relentless torrent of randomly-placed licks that grew more purposeful and precise as the filly developed preferences for the textures and tastes afforded by the different areas of the flesh. Twilight was prepared to pry the filly away when Diamond Tiara did something the unicorn hadn’t been expecting.
Diamond Tiara began wrapping and swirling her tongue around the head as she gripped the shaft firmly and took it into her open mouth. Twilight’s eyes rolled into the back of her head as the damp inferno of the filly’s mouth enraptured her mind. In response to this new development, Twilight found herself involuntarily bucking her hips in a driven frenzy to further immerse herself in the pleasure of the filly’s mouth. Diamond Tiara took note of the other mare’s behavior and tried to pull away only to find herself drawn back as Twilight wrapped her forelegs around the filly’s head and pulled her back down. She wasn’t quite finished yet, but an ascending, swelling sensation from the base of her shaft indicated that she would be soon.
With a few final pumps, Twilight vigorously pursued the the strange build-up, until at long last the mounting pressure reached its peak. She exploded, releasing a hot stream of her essence into the filly’s mouth, her back arching involuntarily as Diamond Tiara’s abrasively amateurish efforts brought the unicorn to her first cross-gender orgasm.
Diamond Tiara, sensing the unicorn’s grip had weakened, pulled away from the encounter, coughing and spitting up as much of the faux seminal fluid as she could without having to swallow. “Ms. Sparkle,” she choked, “what just happened? Why didn’t you give me some kind of warning?”
“Heh, heh, sorry Diamond. It just felt so good that I guess I got a little carried away.”
“That was gross!” Diamond Tiara could feel something sticky trailing down her forehead. “I think you got some of it in my mane too,” she whined.
“I’m sorry about that, but if you’d like, I think I can make it up to you with the next part of our lesson.”
“What are we going to do next?”
“Lay on your back and I’ll show you,” Twilight instructed.
“Alright, but you better not do anything funny this time,” Diamond Tiara growled as she obliged her tutor’s instruction.
“I won’t, I promise,” Twilight chuckled as she crawled between the filly’s hindlegs. “Now I’m going to teach you about the vagina.”
“You mean... my...” Diamond Tiara’s face was blazing crimson as completed her thought by wordlessly motioning to her nethers, to which Twilight responded with a nod. “O-okay.”
“Now,” Twilight said as she set a carefully placed a hoof on the filly’s inner thigh, eliciting a slight shudder from the earth pony that only grew more intense as Twilight slid her hoof closer to her target. “The first and most noticeable part of the vagina is the labia, of which there are two parts,” Twilight explained while tracing the slit of filly’s small mound with her hoof, to which Diamond Tiara shivered and squirmed uneasily. “The purpose of the labia majora is to protect the rest of the vagina from infection by dirt and bacteria. However—” Twilight placed her other hoof on the filly’s pallette, parting the slit to reveal the bright pink color of her unspoiled fillyhood. “The labia minora serves next to no purpose at all.”
Diamond Tiara covered her face with her hooves, feeling utterly embarrassed by the whole situation. The mere thought of having her private place so thoroughly exposed and explored caused Diamond Tiara’s face to grow red and her nethers to grow moist. Needless to say, this did not go unnoticed by Twilight, who cracked a toothy grin at the earth pony’s bodily reaction. “Oh, he he. Did my lesson get you excited, Diamond?”
“Wh-what are you laughing at? Aren’t you supposed to be teaching or someth~♥hyaa♥~!” Diamond Tiara whinnied and covered her mouth with her hooves as Twilight spread the filly’s cleft open wider and slid her own tongue in. “Why are you~♥kaa♥~ doing that? ~♥Hnnn♥~ It feels ~♥hahn♥~so strange.”
“Well, you seem to be getting more out of this than my lesson plan,” Twilight paused to give the filly a slow, deliberate lick before continuing. “And besides, I figured I should return the favor from earlier. Don’t you like it?”
“W-well,” Diamond Tiara panted, trying to catch her breath, “since you put it li~♥ooohh♥~.” The filly’s train of thought derailed quite quickly as Twilight plunged her tongue back into Diamond Tiara’s tightness. As the unicorn probed and explored the filly’s cavern, she could feel the pulsing walls growing slicker and clenching her tongue tighter. Twilight, pleased by the positive feedback, began to suck in as she delved deeper into her pupil. After a certain point, Twilight felt Diamond Tiara’s hind legs tighten around her neck. “Please, Ms. Sparkle, do it harder,” the filly pleaded, to which Twilight merely grinned and doubled her efforts. Through Diamond Tiara’s increased convulsions, Twilight could tell that she was just on the verge of orgasm. All it would take was a few more licks and—
~♥Nyaaaa~aaaa~hah!♥~ Twilight pulled away as Diamond Tiara began to convulse and squirm uncontrollably, savoring and being overwhelmed by the jolts of ecstasy that she had never known before flowing through her. As the euphoria gradually faded away, Diamond Tiara hazily stood up. “Wh-where did you learn something like that?”
“Well, uh, let’s just say that I had a very thorough teacher for a good portion of my life,” Twilight explained as she glanced at a nearby portrait of Princess Celestia.
“Do it again, Ms. Sparkle! Oh, please do it again!” The filly pleaded.
“Hm? Again? But don’t you want to move on to our final lesson?”
“But, we didn’t even finish the first one,” the filly pointed out.
“True... but the point was to get you involved.”
“I still don’t feel like I’ve learned as much about this as I should have, Ms. Sparkle. But if you want to move on then it’s up to you I guess.”
“Don’t worry: this last lesson should cover the rest of the module, quite thoroughly.”
“So, what do you want me to do this time?”
“Hmmm... just roll over and put your flank in the air.”
With only the slightest hint of hesitation the filly obliged her. “Like this?” she asked, voice heavy with innocent uncertainty.
“Just like that, now leave the rest to me. Are you ready, Diamond?” Twilight asked as she pressed her tip against the filly’s moist, waiting hole.
“Will it feel as good as last time?”
Twilight smirked, “It’ll feel even better, trust me.” With no further hesitation, Twilight slid the tip of her new appendage in between Diamond Tiara’s tight, velvetlike folds, moaning as she felt the filly clench around her shaft. For the unicorn, the experience was truly delicious; the constant pulsing heat of Diamond Tiara’s inner walls clenching around her emboldened faux-phallus was nothing like she had been expecting. While stallions may have gotten the short end of the stick as it pertained to orgasms, they certainly made up for it with their consistent penile sensitivity.
However, as marvelous as the experience was for Twilight, it was completely different story for the filly. “It hurts!” Diamond Tiara whinnied, as she scratched and clawed at the sheets in a futile attempt to distance herself from underneath the much heavier mare. “Y...you lied to me, take it out!” She bucked and pressed against the unicorn’s chest, but this only served to drive Twilight even deeper into her.
“It hurt my first time too.” Twilight wrapped her forelegs tightly around the struggling filly’s waist, successfully restricting her movements. “Just bear with it for now! I promise that it gets better!”
“But it—” Diamond Tiara winced and moaned as Twilight began to nip and nibble on her ear, successfully taking the earth pony’s mind off of the sharp pains plaguing her body. She could feel Diamond Tiara growing lax and placid beneath her, and after what seemed like a small eternity, the filly finally breathed a small sigh of contentment.
“How does it feel now?” Twilight purred into her pupil’s ear.
“~just like you promised...~” Diamond Tiara craned her head up and nuzzled her tutor’s neck.
“I’m going to move now,”
“~mmm, please go slow.~”
Twilight gradually drew her hips back, feeling her partner’s tiny body quiver with each inch she withdrew. As she reached the limit of her retreat, the unicorn inched her shaft back into the filly, who cooed in contentment and anticipation for her next injection. Twilight, who was still growing accustomed to her new appendage, once again pulled back and pushed herself forward, eliciting a small yelp from Diamond Tiara.
Again and again Twilight continued her experimental bump and grind, making sure to savor both the slickened heat of Diamond Tiara’s slit, as well as the reward of her partner’s enraptured writhing and moaning that accompanied each successive stroke. As she grew acquainted to the pleasure, Diamond Tiara began to rock her hips against Twilight’s shaft, adding to the unicorn’s pleasure with such noticeable intensity that Twilight had to clench her jaw to keep her focus from slipping away. Twilight was sensed that she was starting to lose control of herself in the ferality of the act, as her hips were simply moving on their own now, picking up speed and power with each thrust that brought her closer to orgasm. She had been feeling the build-up to her climax for quite some time, but had managed to push it into the depths of her mind up until now. She could feel the impending release growing hotter and more intense as she mindlessly pursued the ambrosia of the flesh that her student’s body would soon grant her.
“Diamond Tiara, I’m at my limit,” Twilight grunted between pumps. “I can’t hold this anymore, I’m going to let it out!”
“I don’t mind, go ahead!” Diamond Tiara panted through the abuse.
With one final pump, Twilight slammed her hips against Diamond Tiara’s flank with as much power as she could muster. She released her essence into the pink filly, all the while violently trembling as she struggled to keep herself from collapsing from the sheer force of the orgasm as it ripped through, and ripped apart, her magical member, reducing it to nothingness in a puff of purple smoke.
Absolutely spent, Twilight collapsed on the bed, panting and heaving as she allowed sleep to overtake her.
Epilogue Coming Soon
