The Big Test

Sercw Me Sneselses Tihwglit

By: Sirius Face

“I came early, princess!”

Dinky Hooves trotted into the Golden Oak Library—Pinkie Pie levels of excitement coursing through her veins—she was ready to ace her big test. Her mother, more reserved, followed behind the excited filly. Derpy took time to wipe her hooves on the doormat before entering the neat and orderly library.

From the second level of the hollow tree, Princess Twilight Sparkle stuck her head over a railing to see her first ever student grinning up at her. Twilight spared a second to wonder if she ever gave Princess Celestia a smile like the one Dinky was now giving her.

“I hope you don’t mind,” Derpy asked in her usual bubbly tone betraying her actual age. The mare gave Twilight an adorable, cross-eyed apologetic look, “It was all she could talk about this morning. I hope we haven’t come at a bad time.”

Twilight smiled and disappeared in a blink of purple light, reappearing a foot away from the excited young filly and her mother. Dinky didn’t hesitate to approach the alicorn and hug her like a best friend, knowing Twilight didn’t mind in the least. Twilight returned the hug with a single front leg. The recently coronated princess was without her crown, or royal garbs, preferring to stay practical when she was home. Since returning to Ponyville, everypony soon realized Twilight was still the same bookish pony she had always been, with the only change to her routine being starting a service to tutor young unicorns in the ways of magic.

“I don’t mind at all. I’m happy Dinky is so excited to take her test today.” Twilight said, giving Dinky a smile, recalling how she used to be excited for Celestia’s magic tests. The sense of nostalgia made her almost as excited as her student. “Go ahead and take a seat at your desk, I’ll be there shortly.”

Dinky gave a quick nod and hurried to one of the chairs at the center table, where a bust of a stallion head stood watching. Twilight turned back to Derpy, who had already placed a brown paper bag by her hooves.

“I made these for you.” Derpy smiled, “You know, I don’t mind paying you for Dinky’s lessons.”

Twilight lifted the bag with magic, already able to smell the warm baked goodness. Muffins, Derpy’s specialty. How the mare didn’t have a muffin for a cutie mark was beyond Twilight. “I’ve already told you, I don’t want to be paid. Every unicorn should have the chance to learn how their magic works. Now that I’m a princess, the least I can do is show some leadership to the next generation of unicorns. Teaching them what I can is all the reward I need.” Twilight opened the bag to see a collection of small chocolate muffins with generous portions of chocolate chips baked into them and smiled at the sight. “Getting home baked muffins is a nice perk though.”

Derpy looked pleased and caught Twilight off guard with a sudden hug from her wings. “You really are the best princess ever!”

Twilight wanted to argue that point but let it go, choosing instead to hug Derpy back before pulling away. “Thank you Derpy, and thank you for the muffins too. I’ll see you in three hours then?”

Derpy gave Twilight several nods before waving to her daughter, who had already set up her supplies on the desk, clearly ready to learn. “Have a good test, Muffin!”

“Thanks momma!” Dinky waved as her mother left the library.

Twilight called out a farewell once more, then flipped the welcome sign on the library door to closed so that no pony else would disturb them. The locks clicked in place with Twilight’s magic and she faced Dinky, who was eagerly waiting to test her new skills in magic.

“Is it hot in here?” Twilight asked.

Dinky’s excitement was briefly forgotten once she heard the question. Her eagerness over the test was replaced by the sudden realization she was feeling warmer than usual. It wasn’t very hot outside, despite it being cloudless and sunny. Focus on the day’s activities had kept her from realizing just how warm she felt all over.

“A little bit, actually,” Dinky said, her cheeks blushing.

“I really need to talk to Rainbow Dash about getting a winter cloud to blow cold air in the library. I’ll shut the windows to keep the heat out—go ahead and take out your notes from last week. We’ll start with a review and then take the test on telekinesis.” Twilight smiled as her magic lit up, a purple aura reaching out to each window in the library, shutting them all at once. The outside world was quickly banished.

“Already got my notes, princess.” Dinky indeed had a notepad out in front of her, lines filled with surprisingly neat mouth-writing. Twilight chuckled, once more surprised by how much the little filly reminded her of herself at that age. Being called princess made Twilight’s stomach flutter. It would take some getting used to for her to be okay with Dinky, or any other future students, calling her by the title she still used for her own teacher.

Correction—my equal, not my teacher anymore.

A sobering thought, it brought Twilight’s attention back to the task at hand. Seeing how ready Dinky was, both in terms of her natural magical ability and in her preparedness for the test, Twilight couldn’t think of a better filly to be her first student.

“Alright then, my little pony. Let’s start with the basics. Can you tell me the definition for telekinesis?”

Dinky didn’t even have to look at her notes to answer Twilight. “Telekinesis is the paranormal force that can move objects at a distance.”

“Correct,” Twilight said as she stood at Dinky’s side. “Telekinesis is the most commonly used form of magic by all unicorns. It is also gateway-magic for using other, more complicated spells, such as teleportation. When unicorns have an understanding of how their magic can reach out and take hold of things at a distance, it allows them to know how their magic feels and how to multitask with it.”

Dinky, pencil in mouth, took notes while Twilight lectured on the theory of telekinesis. Dinky knew she could use her magic to move the pencil, that much she had mastered, but she wanted to save her magic for the complicated test that she knew was coming.

“Now, any unicorn can move an object with magic, but can you tell me how telekinesis works best?” Twilight asked.

For this, Dinky did pause to refer to her notes, setting her pencil down and out of her mouth. “By understanding the laws of perspective!” she said with a voice that was nearly as bubbly as her mother’s, though not as high pitched.

“Very good. Now with that in mind, we’re going to launch into a minor review and begin the test. Do you feel ready for it?”

Dinky nodded, and the excitement on her face positively shining. She moved away from her desk to stand in front of Twilight, as her teacher’s horn started to glow.

Twilight’s magic steadily grew brighter and brighter, the light simmering like heat on a dry road. The light was animated, pulling off Twilight’s horn in a shapeless glowing blob and splitting into parts that grew and stretched into shapes. Before Dinky’s eyes, Twilight conjured several three-dimensional rectangles, some with staircases that lead to nowhere and others with holes in them

From one of the rectangles, the small featureless white pony sprang up from its surface. Three other black pony figures emerged on different rectangles in similar fashion.

It was an impressive spell, one Dinky saw Twilight use before when explaining lessons, but have never actually used herself. Once the white pony started walking on his small rectangle, Dinky knew her test was about to start.

“Alright now, I’m going to explain the laws of perspective one more time before I give you this test. What you need to do is help this white pony reach his shadows on the other spaces using your telekinesis to create paths that you can see for him. There are twenty four patterns I’ve enchanted in this spell, and they get a little harder as you reach the final patterns. If you can figure out the puzzle of each pattern, you pass your test.”

As Twilight explained the test to Dinky, she moved the three dimensional rectangles three hundred and sixty degrees, showing Dinky the location of the rectangles was locked into position.

“Now reach out with your magic and take hold of this space I’ve made. I’ll hold it with you, but for now I want you to get a feel for the spell I’ve made.”

Dinky nodded and focused the magic in her horn, making it glow yellow as a freshly bloomed sunflower. With Twilight’s lessons in mind, she felt her magic reach out like an extra limb and blend into Twilight’s aura. The sensation was chilling—Twilight’s magic felt cold as it enveloped her own warm magic, allowing Dinky to slowly spin the three dimensional object like Twilight had.

“Got it?” Twilight asked, smiling because she knew her student was already taking control of the complex spell.

“I think so. It feels like I’m holding one thing instead of all those little rectangles.”

“That’s because you are. You’re holding the space that holds those shapes. What you need to do is move the space in specific way to help the white pony reach his shadows. You’ll have full control of moving this space, creating paths for him to follow. For that, I’m going to explain the laws of perspective one more time to you.”

With her magic still holding the spell, Twilight coaxed Dinky’s aura to tilt the space of the spell forward, making Dinky see stairway that lead to nowhere suddenly connect to the rectangle the white pony was walking on.

“The first law is perspective traveling. If objects appear to be touching, they are in fact touching. Now the second law is perspective landing. If an object appears underneath another object,” Twilight explained this as the white pony figure walked down the small flight of stairs towards a hole in the new rectangle it was on, falling in slow motion to a rectangle under it, where it regained its balance and walked up to a pony shaped shadow. “It is underneath it.” Twilight said with a smile.

Dinky watched as Twilight positioned the spell to create paths for the animated pony to follow. From her perspective, the entire shape of the floating objects took on new forms with a few simple rotations. What she didn’t realize was in the empty space made by those floating objects, letters were made.

She wasn’t meant to notice that though. Consciously, at least. Twilight made the figure the main focus of the test. Dinky’s subconscious would notice the letter, which was what Twilight wanted all along.

“See? Now remember, these laws are not true laws in the technical sense of the word. They help give confidence to young unicorns who are using telekinesis for the first time. When I first learned them, it was like discovering an additional limb I never knew I had.”

Twilight smiled more, happy to see Dinky so attentive to the spell. They both watched as the white pony figure reached the first shadow, mounting it from behind for a split second, before the shadow disappeared. It happened so fast that Dinky couldn’t be sure she saw the action at all.

Twilight knew her student had seen it though. All the little details, too fast to be sure of, but still there: the shadow lowering its front legs while raising its rear, the white figure mounting the shadow, giving a quick thrust of its genderless hips.

“Now,” Twilight continued, speaking softer, “the next law is the law of existence. If the gap between two pathways is blocked, they’re actually connected together. Then finally there’s the law of absence, where if something can’t be seen, such as a hole in the object, then it isn’t there.” Twilight showed this by rotating the floating structure just as the white pony was about to step into a hole. The movements were quick and precise, the white pony appeared to have walked unobstructed to the next shadow, mounting it eagerly.

While Twilight lectured, she continued the delicate brainwashing of her student, which soon Dinky would be doing to herself. Letters would be spelled out in front of Dinky without her knowing it. In the time it took for Twilight to arrange the puzzle, and for the white pony figure to take its three shadows, she had spelled the word ‘heat’ in the air several times.

“Think you’re ready for your test?” Twilight asked, struggling to keep the secret of the test to herself.

“I’m ready, princess!” Dinky said, taking full hold of the space in her magic.

“Okay then, my faithful student. Your test begins now.”

For an hour, Dinky practiced her telekinesis on the spell Twilight had made. Every completion of a pattern changed the orientation, adding in more horizontal and vertical rectangles or taking some away, likewise with stairs and holes.

Of the twenty four patterns Dinky needed to finish, she had completed half of them, and subconsciously read Twilight’s subliminal message letter by letter:

Sex is all I want screw me senseless Twilight

For her part, Twilight quietly watched Dinky arrange the spell in the ways she wanted. All of Twilight’s lessons involved some form of subconscious messaging meant to prepare Dinky for the real test.

She’s almost ready. Two months of mental suggestions should be enough, assuming my hypothesis is correct. Even if it isn’t, I still have safety words to bury anything I don’t want her to remember deep into her subconscious.

Twilight smiled, feeling proud for developing such a complex spell that would, in theory, make a pony aroused any time she wanted. With her new powers as a princess, she discovered the new things her magic could do. Like putting magic into magic, creating a kind of mind control that was on level with the changeling ability to make a host pony willingly surrender their love. With a little tweaking, and several test spells, Twilight managed to develop something that would have Dinky surrender something more enjoyable than just an arbitrary emotion.

“Is it hot in here?” Twilight asked suddenly.

Dinky paused her movement. Twilight caught the filly visibly shudder.

“Y-yes… it’s kind of warm in here…” Dinky responded as she started moving the spell around once again, unknowingly forming the last letter of the word ‘cum’.

“Good.” Twilight muttered. Before launching her plan, she had prepared trigger phrases for Dinky. Since the filly was most likely too young to have experienced her first heat cycle, Twilight subconsciously amplified feelings that mimicked the sensation of being in heat through magical exercises. Like the three dimension space she was testing Dinky with at the moment, or other more direct exercises disguised to help Dinky learn how her magic ‘felt’ inside her. Those exercises always began with the same phrase that over time would cause those subconscious feelings to feel real, or so Twilight believed.

Twilight smiled, watching Dinky try to ignore the feelings in her body. The filly’s subconscious mind driving the instinct to mate, pumping blood to the area between her thighs. A low but constant tingle between her hind legs. A growing sensitivity to air and an uncanny need to sniff the odors carried by it coupled with an inability to focus that became stronger every time Twilight fed Dinky the trigger phrase.

“Just keep at it. I keep wondering ‘is it hot in here’ and I’m glad it’s not just me...” Twilight felt her wings stiffen as Dinky shuddered again from hearing the trigger phrase, “but once you’re done with the test we can take a break.”

“O-okay, princess,” Dinky stuttered as she started sweating.

Twilight had to give Dinky credit. Her faithful student had for over an hour been going through an adult heat cycle, albeit very toned down symptoms that grew stronger bit by bit. It hadn’t stopped Dinky from wanting to complete her test and further the study of her own magic.

I wonder… if I stood next to her, could I smell her?

Twilight felt her wings stiffen more as an ache between her own hind legs started to grow from nothing to a sudden and sure need. She was really going to rut Dinky tonight.

If all her complex spells and mental suggestions worked on a still developing mind like a young filly, then it meant Twilight could test her procedure on an older pony with a more developed mind. Dinky was the first in a series of experiments, until she felt sure the conditioning would get her the pony she really wanted wet with nothing more than a simple, innocent question.

Twilight licked her lips, imaging for a moment an older, wiser, more powerful pony in Dinky’s place, planting lewd and perverted suggestions into Celestia’s mind thanks to Twilight’s new magic.

“Is it hot in here?” Twilight asked again once she noticed Dinky was nearing the last pattern in her telekinesis test.

This time, Dinky gasped and nearly lost control of the spell, the aura around her horn flickering as if it would go out. Twilight made a mental note that prolonged exposure to suggested heat symptoms resulted in severe weakening of magic utilization. She was sure Dinky was squeezing her hind legs together as she stood. Twilight realized Dinky’s tail hadn’t been moving for a while, no doubt trying to hide the shame in the little filly’s nether regions.

“Y-y-yeah… it’s really hot in here, princess.”

“I’ll get you a drink then. You’re almost done with your test?”

Dinky gave a quick nod, her aura still flickering as she worked out the last pattern. For well over an hour she had been spelling Twilight’s perverted message out, watching animated pony figures mating one movement at a time, while feeling a strange attraction to a place she knew she couldn’t touch in public.

“I… I just finished it!” Dinky smiled, watching the spell dissolve as the final pattern worked out.

Twilight walked up to Dinky’s side, wrapping a large wing around the filly. She could, in fact, smell Dinky.

“I’m very proud of you Dinky. Not every filly has the patience or the natural talent to do what you just did. I know your mother is going to be very proud of you too. I bet you’re feeling pretty tired by now huh?”

Dinky only nodded at Twilight’s question, smiling over her accomplishment but also struggling with the new sensations in her body. Her eyes looked as if they were watching something far away. Twilight suspected they were still seeing the hidden message Dinky spent so much time to make:

Sex is all I want screw me senseless Twilight make me cum make me squirt make me your breeding slut I’m hot and wet for you

“Dinky?” Twilight asked with a knowing smile.

“Oh,” Dinky gasped, looking up at Twilight with a bright blush creeping up from under her delicate facial fur, “I’m sorry princess, what did you say?” There was a slightly concerned look on Dinky’s face, as if she was suddenly aware of the aroma wafting off her backside.

“I was asking you, is it hot in here?”

Dinky’s eyes widened and she shuddered against Twilight. Her breathing quickened, the prolonged sensation becoming impossible to ignore without the distraction of her test.

“I don’t… feel right…”

“Sounds like you wore yourself out. Come on, you can lay down in my bed. Can you still walk?” Twilight asked, her own heart beginning to race at what she was going to do soon.

“I think so… what’s w-w-wrong with me, princess?”

“You used a lot of magic today and your body needs to rest.” Twilight nuzzled Dinky, something she had never done before and would normally never do to a small filly. Dinky was too out of it to notice the overly-affectionate gesture, body accepting her teacher’s touch and familiarizing with the concept of heavy petting.

Twilight nudged Dinky to start walking, smiling sweetly to her all the while. When she moved her legs to walk she realized something unspeakable had happened while she had been trying so hard to focus on her test.

The sudden stiffness in Dinky’s body made Twilight pause, the formation of tears in Dinky’s eyes almost made her think that her spell hadn’t worked the way she had intended, but she was confident there would be no errors in the commands she meticulously prepared and reinforced.

“Dinky? What’s wrong?” Twilight spoke with genuine concern—worried perhaps something had gone wrong with the spell.

“I… I’m sorry, princess… I didn’t… didn’t know…”

“Didn’t know what? Are you crying? Please tell me what’s wrong?”

Twilight moved in front of Dinky, wanting to see her face. The musk from the filly was stronger now, strong enough for Twilight to taste in the air. There was no way Dinky couldn’t smell herself.

Twilight pretended not to notice. “Dinky? Talk to me sweetheart.” Twilight asked again.

Dinky didn’t respond right away. By the time she managed to speak, tears spilled from her eyes.

“I... had an... a-a-accident.” Dinky whispered.

The admission caught Twilight off guard. She didn’t smell urine, and quickly looked down at the floor where the filly was standing.

Dinky was wet. Wetter than Twilight could have imagined a young filly without her cutie mark could be. The fur on inside of her hind legs practically soaked, a small puddle forming between her hooves.

The look on Twilight’s face made Dinky sniffle, but she held back the urge to run away and cry. Her mother liked to say she was ‘so mature for her age’. Had she been paying attention, she would have noticed the tempered look of joy on Twilight’s face.

This is even better than I predicted!

“It’s okay... really Dinky, it’s okay. You didn’t have an accident. You’re just in heat.”

Dinky turned to face Twilight’s tightly controlled smile and excited eyes. She didn’t understand the look Twilight was giving her, only that it unsettled her a little.

“In heat?”

“Yes... it means you’re becoming an adult, entering maturity—ready for copulation. All mares go through this. It’s nothing to be scared of Dinky. It’s perfectly normal. The wetness between your legs is just your body’s way of showing how ready you are. It’s not bad at all.”

Twilight gave Dinky a reassuring smile throughout her explanation. And the calm tone did much to make Dinky feel less ashamed over what she had unknowingly done to herself. The look on Twilight’s face still a little unsettling. Though it was enough to keep Dinky from bursting into tears.

“Come on, follow me and we’ll clean you up.” Twilight said as she guided Dinky to her side, gently pushing with an outstretched wing. Dinky sniffled once more, following next to Twilight, her legs trembling slightly.

“This... hasn’t happened before...” Dinky spoke softly, logically explaining her situation to Twilight, despite being told that what had happened to her was normal. Dinky’s face suggested she felt anything but normal as she and Twilight approached the stairs.

“Sometimes ponies can become aroused for reasons they don’t fully understand. It happens quite often to young fillies and colts. Does it feel like butterflies storming in your stomach right now?”

Dinky blushed a little more as Twilight’s question made her think about the sensations in her body she was trying to ignore. She could only nod at Twilight’s question.

“I bet that isn’t all, is it?” Twilight asked, speaking as if she were sharing a secret. “Does it feel like there’s this... throb between your hind legs? Almost like an ache, that doesn’t hurt but you can’t ignore it? Is it making you squeeze the muscles back there, muscles you didn’t know you actually had until they started moving on their own?”

Twilight could almost hear Dinky’s heart racing as she so casually brought up all the humiliating things the little filly’s body was going through. Dinky nodded again, the blush on her cheeks getting deeper as they went up the stairs and into Twilight’s bedroom.

“Good!” Twilight’s smile grew, and the feathers of her wing brushed along Dinky’s side, flicking off her small blank rump and making Dinky squeak with surprise. “These are all signs of a healthy heat cycle. Don’t let it upset you. When a mare enters her cycle, it just means she needs to mate. Of course, you’re still too young to mate with a colt! But there’s other ways to help your body. Do you want my help, Dinky?”

Dinky looked unsure, feeling as if something wasn’t right, like Twilight wasn’t telling her everything. But the tension in her body was making it hard to think, and the smell of her arousal was impossible to miss, making it hard to make decisions for herself. She’d rather just listen to her teacher. After all, Princess Twilight was smart and she had been through all this before...

“But this... doesn’t feel right...” Dinky whimpered.

Twilight’s smile never faltered as she used her magic to gently push Dinky to get onto her bed. “It’s a little scary, the first time you go through your heat cycle. Go ahead and lay on the bed. I bet it will help to get off your hooves.”

Dinky didn’t need much prompting to follow Twilight’s orders. She sighed as she lay on her side, sinking into the plush comforter of Twilight’s princess-sized bed, panting still and feeling very flushed. Twilight couldn’t help but lick her lips at the sight of such a hopelessly aroused young foal. She never considered herself a foalfidder before, but the power play she was experiencing made her more excited than she expected she would be for this. She had Dinky completely at her mercy.

“Do you want me to leave you alone, Dinky?”

There was confidence in Twilight’s voice, but Dinky was too distracted to notice. She shook her head. The thought of Twilight leaving her never crossed Dinky’s mind until the princess mentioned it. And now that she had, the little filly couldn’t bare the thought of being left alone with this feeling between her hind legs.

“No... stay with me.”

“Of course, my little pony. Your princess is right here.” Twilight crawled up on the bed, resting by Dinky’s side. Having had months since her coronation to learn how her wings could function, Twilight reached over Dinky, brushing the soft tips of her feathers along the side of her faithful student. Dinky moaned as the feathers teased her, coming back damp.

“You’re sweating. Is it hot in here?” Twilight asked sweetly.

Dinky didn’t hold back her moan as she squeezed her hind legs tightly, the protrusive paunch of her sex deeply alluring.

“You are hot, aren’t you? And you’re obviously wet too. Will you show me? Show me where you feel so hot and wet?”

Twilight’s voice was sweet as honey, sticking in Dinky’s mind and muddling her ability to resist as feathers brushed along Dinky’s side; it was time to see if the subliminal messages had worked the way Twilight intended them to.

Without much resistance, Dinky rolled onto her back. Her small chest rose and fell at a steady pace. She relaxed her legs, exposing her dripping crevasse to the air. The damp fur near it standing on end, waiting for... something, but the little filly knew not what.

Twilight felt her own heart racing; Dinky was winking at her. Her small sex was a pretty shade of light pink, opening and closing invitingly, a dollop of nectar flowing down, trickling over her tightly budded anus. The musk from the filly was getting stronger with time, a mix of sweetness and saltiness Twilight couldn’t categorize. It was a musk unique to her student, one that made Twilight’s mouth water.

“Princess?”

Twilight blinked, realizing she had been starring. Also Dinky looked scared.

“Remember, this is normal for a filly. Your body’s heat cycle is it’s way of telling you that you’re ready to attempt breeding now. Or, if you want to be less technical, to have sex.” Smiling deviously, she let slip one of the trigger words, "you may have heard younger ponies refer to it as 'screwing’.

Dinky bit her bottom lip, unable to pull her eyes away from Twilight’s face as she mused over the meaning of the words, sounding rather familiar.

“I... want to have sex...?” Dinky asked.

Twilight nodded, continuing her gentle petting of Dinky’s side with her feathers.

“That’s right, Dinky. That’s what it means to go into heat. When a mare feels this way, it means she wants, or rather, she needs to achieve orgasm. That’s the ultimate form of pleasure for a pony to experience. It’s very special.”

Twilight nuzzled Dinky again, letting her feathers rub teasingly along the inside of Dinky’s hind legs, lacquering them in a thick syrup Twilight knew didn’t come from sweat.

“Does it feel like you need an orgasm, more than anything else? Do you want me to help you?”

Dinky gasped and looked up at Twilight with apprehension in her bright eyes. Her body was screaming yes, but a tiny voice in her head whispered no.

“Dinky? Is sex what all you want right now? Are you all hot and wet right now, just for me?” Twilight asked, her lips brushing against Dinky’s ear as she whispered her questions.

The response Twilight got was sudden. She watched Dinky’s eyes glaze over, the mental suggestion the filly received suddenly kicking into full power. Logic and reason were silenced as Dinky thrust her hips up into the air, her body mimicking the quick humping motions she spent over an hour watching without realizing it.

“Yes,” Dinky moaned.

Experiment number one:success. Twilight grinned and slowly lapped at the corners of Dinky’s mouth, grinding against the filly’s side. She glided her smooth hoof from Dinky’s stomach to the source of heat between her student’s legs.

Dinky moaned like a shameless mare, but with the squeaky voice of a confused and desperate filly. The sight was more arousing than Twilight could have imagined in her lewdest dreams. Twilight traced her hoof around Dinky’s puffy sex, careful to never touch it as she gauged Dinky’s reaction.

She looks so... desperate. Helpless even?

Twilight’s hoof continued its circumnavigation of Dinky’s winking sex, helping to mat down the fur, surprised at how much softer the dry fur looked under Dinky compared to the rest of her coat.

Dinky’s moans and whimpers never stopped, much to Twilight’s enjoyment.

I’ve got her. I bet I could do anything now and she wouldn’t say no.

Twilight caught herself hyperventilating in excitement and from how successful her experiment had been. It wasn’t completely over, but now she could at least enjoy it.

I... I can do anything to her. Anything I want.

Twilight positioned herself a little lower, sliding on the bed in front of Dinky, gently pushing her hind legs open to allow herself a better view of Dinky’s glistening mound.

Her breasts are still flat. I can barely make out her nipples. And her smell...

Twilight licked her lips, wafting the aroma into her nose. Shivering from the delicate fragrance, like a new book smell. Even her own musk never smelled this powerful, but Twilight had to remind herself she had never gone such a long length of time being aroused without so much as touching herself. She had never been as wet as Dinky was at that moment.

She looked up to Dinky’s face, her glassy stare indicative of the filly giving into her lust, subverting the will to resist her princess.

It felt time for another test.

“You smell wonderful down here, Dinky.”

Dinky didn’t respond. She didn’t even seem to hear Twilight’s perverse comment.

Twilight tried again.

“You smell so good, it’s making my mouth water.”

Dinky’s only reaction was to quicken her breathing.

Nervousness began to gnaw at Twilight. The only way to really be sure that she had full control of Dinky was to simply use her. She reminded herself there were other commands she could use to make Dinky forget anything Twilight needed her to forget. And that there was no real danger of Dinky resisting at this point.

Reassured, Twilight crossed another line in her experiments. She lowered her head to press her snout against the hot and soaked foalhole. The heat could be felt in her nostrils. Closing her eyes, Twilight took a long, deep sniff of Dinky straight from the source.

Oh Dinky...

Twilight’s body tensed as her wings stood at attention. She pressed her own aching mound against the bed as she breathed in concentrated lust from an innocent, unsuspecting young mare. Twilight’s brain lit up like fireworks exploding all at once. She sniffed Dinky again, making the filly whimper in desperate need as she mindlessly humped her teacher’s face. It took only a few thrusts to coat more than half of Twilight’s face in filly juice.

Twilight didn’t pause to consider if she should or shouldn’t stick her tongue out to taste Dinky; her tongue was already forcing its way into Dinky. It wiggled to try and fit inside the narrow tunnel as Twilight’s nose rubbed on Dinky’s super sensitive clit. Twilight had never gone down on a mare before, but lack of knowledge didn’t hold her back. If anything, it made her over-eager to please as she licked and suckled and kissed Dinky’s mound, greedy for an endless supply of love juice. Her front legs hooked up and over Dinky’s hind legs, lifting her up to get a better angle, allowing Twilight to push more of her tongue into the small honey pot.

Twilight had full control over Dinky’s free will and could twist it to her own perverted desires. It was the most sexually provocative thing she had ever experienced.

A small voice in the back of her mind reminded Twilight to test many, many other fillies before she could move on to mares, and finally to Celestia. There was so much to plan for and so many kinks Twilight had only read about that she wanted to try. In Twilight’s eyes, Celestia’s generous flank was a prime target for anal sex. She could see herself easily spreading Celestia’s graceful hind legs and performing cunnalingus, after making her mentor participate in an exchange of pillow talk. She would make her teacher beg for a horn job and Twilight, ever faithful, would finally get to lick every groove of the alicorn’s horn. And tribadism, getting to rut Celestia like a common breeding mare... that would be Twilight’s favorite part.

She was so caught up in future plans that Twilight nearly forgot about the one kink she couldn’t do with Celestia: foal fucking. Someday Celestia would be in Dinky’s place—on her back, in heat, at Twilight’s mercy—but until then, Twilight was going to celebrate by letting loose and taking full advantage of her first success.

She pressed her mouth over the whole of Dinky’s snatch and sucked as hard as she could, drawing a sweet but mostly salty taste from the slit. Dinky, unable to form words thanks to the complete control of Twilight’s conditioning, began to vocalize her pleasure in short, squeaky shouts. Her hips wiggled, trying to allow Twilight better access, as the princess’ tongue cut between the filly’s thighs. Lapping the walls of her pussy, it opened Dinky up to the prospect of perhaps having something firmer inserted inside her.

Twilight moaned as she felt Dinky squeeze her tongue, the filly’s body trembling in Twilight’s hold as juices ran down her teacher’s chin. Twilight listened as Dinky’s moans turned into loud, high-pitched whimpers. Dinky’s primal urges took her, the need to mate overpowering conscious thought.

There was no time to for Twilight to avoid the first squirt as Dinky creamed into her mouth. She pulled her face up as the second and third squirts soaked the bottom half of her face. The rest of Dinky’s first orgasm soaked the comforter, creating an impressive and dark wet spot.

Twilight laughed, licking her lips as she continued to hold Dinky close to her face.

“You ejaculated!”

Twilight’s eyes were wide with excitement at the discovery. She couldn’t be sure if this was just a natural reaction of Dinky’s body, or the work of her mental suggestions. The fact that Dinky could even experience such an intense orgasm was astonishing.

Regardless of the source, the result made Twilight’s pussy throb harder.

“Let’s... let’s help you do that again. After all, we should be conclusive with our discoveries.”

Twilight pulled Dinky by her hind legs, dragging her over the warm wet spot she had just made. Her body deep in the afterglow of an impressive orgasm was a rag doll: making no show of resilience as Twilight turned her over and push her face first into the mess she made.

Raising Dinky’s hips up, Twilight forced her into the position the shadow ponies in her test had taken, showing off her newly christened marehood. It was a position she was subconsciously familiar with. Twilight lit her horn, wrapping her magic aura around Dinky’s messy mane, pushing her student’s head down.

“You look good with your plot up in the air,” Twilight commented as she used her magic to keep Dinky’s tail flipped up.

Using wings for balance, Twilight mounted Dinky, her larger body almost completely covering Dinky’s as she pressed her own aching marehood against the wet foalhole she had feasted on.

It was a tricky position; one Twilight had to adjust to before shamelessly humping her student. The position was one she always wanted to try, and it would show no signs of physical abuse on Dinky afterwards. She knew that there were easier positions to trib with Dinky, but none of them allowed Twilight to also shove her student’s face into her own mess.

Dinky couldn’t complain. Her moans were muffled by the mattress as Twilight took what she wanted, confident in her control, eager to feel the filly gush against her own needy sex.

Twilight slapped her hips roughly, making Dinky’s blank flank jiggle as it was spanked. Her clit teased against a puffy slit, earning excited moans from Twilight as her own pleasure quickly started to build.

“You’re so soft... so fuckingsoft,” Twilight groaned into Dinky’s ear, licking her face, letting the juices solicited earlier from Dinky’s snatch drip on her, admiring the faraway look in Dinky’s eyes. “Ejaculate again. I want to feel you do it on me. I’m not going to stop until I feel it!”

Even as she said that, Twilight felt she was at her limit. Dinky was smoother than silk, and only getting hotter as she got humped. Twilight held back as much as she could but her hips didn’t slow down.

I’m not going to last much longer... this is going to be big! Gotta try not to scre—

It was Dinky’s fault. Mid-thought Twilight felt her student follow through with the command she had be given and gushed against Twilight. The sensation of her pussy being showered in filly cream made Twilight scream as her own orgasm followed. She didn’t gush like Dinky, as her juices were lost in a shower of filly cum that ran down Twilight’s hind legs and further ruined her comforter. Twilight’s orgasm stole her breath away and made every strand of her fur stand on end. She felt tears in her eyes as her body reached a level of bliss she’d never known before. Twilight laid on her side moaning as the afterglow of her orgasm made her dizzy with joy and pleasure.

“Now... pay attention to the sound of my voice.”

Twilight couldn’t stand steady. Even after allowing herself time to rest and recover, her legs didn’t want to move. Cum and sweat matted her fur and made her mane look disheveled, Dinky in similar fashion.

She hadn’t moved off her belly after Twilight dismounted. Recovering from the induced intercourse, Twilight wondered what Dinky would make of having her physical needs met for the first time, despite the fact that she was no longer in heat. Only further experiments would confirm that thought.

“I’m going to clap my hooves three times. On the third time, you will only hear my voice. You will do as I say.”

Twilight’s horn began to bubble with light as she stood over the edge of the bed, looking into Dinky’s blank face. She wouldn’t wait long before doing more fun experiments with Dinky in the future. With a quick leap, she stood on her hind legs and clapped her hooves.

The change on Dinky’s face was fast. The blank look eased on her face, eyes half open and muscles relaxing. This was always the crucial part of Twilight’s procedures. There was magic in Twilight’s next words, and every one had to be clear.

“I will count from ten to one, and as I get close to one, you will fall deeper and deeper into sleep. You will not wake up until I clap my hooves three times and say your special name. When you wake, you will not remember any of this. You will remember passing your test, and needing a nap. You felt tired, because you used so much magic. Do you understand?”

“Yes,” Dinky whispered.

Ten. Falling asleep. Your eyes are heavy, your body is tired.

Nine. Falling asleep. Your eyes are heavy, your body is tired.

Eight. Falling asleep. Your eyes are heavy, your body is tired.

Seven. Falling asleep. Your eyes are heavy, your body is tired.

Six.

Twilight stopped. Dinky’s eyes were shut, and her breathing was normal. She would sleep and not wake until the command was given.

“Now... we need to get cleaned up. I wish Spike was here to get me a sponge and some warm water,” Twilight mentioned sarcastically. She stopped to really look at her bed, seeing how wrinkled and stained it was and how there was a small trail of wet spots on the hardwood floor leading from the bed to stairs. “It’s a good thing I know your mother won’t be back on time. If I’m going to be ruining my bed like this though, maybe I will start charging her...”

It took more time than Twilight would have liked to clean up. Dinky’s fur was very matted, and the smell of sex seemed determined to stay. All the windows were open to air out the library, prompting Twilight to add to her checklist for the next experiment with Dinky to include building a new room in the library, one that would make it easy to conduct her experiments in private and not have to worry about a mess to clean up later.

With both their manes and tails brushed, Twilight levitated Dinky down the stairs and onto a couch. A bit of nervousness stayed with Twilight as she went over a second checklist, a record of how Dinky needed to look before Twilight could wake her up. After a triple check, Twilight felt a little confident—the last test of her experiment would be seeing the conscious after-effects in Dinky’s body.

Standing on her hind legs once again, Twilight clapped her hooves three times and gave the trigger phrase that would officially end her experiment.

“Love muffin?”

The first reaction was a groan, followed by Dinky raising a foreleg up to rub her face. She didn’t look too comfortable, and her discomfort was Twilight’s discomfort.

“Have a good nap?” Twilight asked, trying not to look nervous.

Dinky didn’t respond right away, but when she turned to Twilight, it became easy to see she was not rested.

“Princess? How’d I get here?”

“What do you remember?”

Dinky thought to herself, rubbing her eyes all the while and licking her lips as if they were dry. Twilight bet that Dinky could use a tall glass of water, or three. Twilight saw her swallow a few times before answering.

“I... passed my test. You were really happy. I got really tired though... I don’t remember anything else.”

The relief that washed over Twilight put a huge smile on her face.

“You were practically ready to fall off your horseshoes. I misjudged the advance nature of my test and worked you too hard. You tapped your magic reserves and started putting strain on your body. It wasn’t a lot, but for your first time using telekinesis for so long, you weren’t properly prepared. That’s my fault though, and I’m sorry for that. Are you thirsty?”

Twilight already had a chilled glass levitated to Dinky, who looked grateful, taking it in her own magic. A yellow sparkling aura effortlessly held the glass as Dinky guided it to her lips and drank greedily.

The sight made Twilight happy on several levels.
