Remedy squeezed her thighs together in her seat and grunted inaudibly as the teacher prattled on. The waves in her nethers had already returned to full intensity and there wasn't a damn thing she could do about it. She could try meditating again but then she couldn't absorb the lecture. She could head to the bathroom with her MagiColt but then she'd still miss out on the lecture and for what? Just to achieve a few minutes of serenity before needing yet another session? That thing barely fit in her locker and she'd prefer to not be seen with it.

Her sustained arousal and constant squirming had made her seat slick beneath her rump. Again, she mopped it up discreetly with her tail in one hoof, planning to hit it with her grandmother's perfume after class. She was sure everyone in a two desk radius could smell her and that was just one more miserable thing she couldn't put out of her mind.

The constant physical discomfort was maddening. The social anxiety was mortifying but the drag it put on her studies was the worst of all.

"Alright, class," began the teacher in the wake of her spiel. "I want you to get into pairs for this project."

Oh, great, thought Remedy. I don't even want to be near anyone. This is going to be so- She quickly looked to her two best friends, Lumen and Crystalline on the far side of the classroom. They sat together; of course they had paired off already. Now what? She just wanted to disappear from the situation and do the project alone.

"H- hey, Remedy," came an anxious colt's voice from beside her. "Wanna be partners for the project?"

Her heart skipped a beat at hearing the words but she wasn't sure if it was joy from somepony reaching out to her or fear of being noticed right now. She turned her head to see a tall but scrawny yellow crystal pony with a slicked back light blue mane. It was Crash Cart. The two of them shared a mutual affinity from physical proximity and comparable intellect, especially in matters of science and medicine. She allowed him to address her by her first name.

Her eyes connected with his. Then they went down and back up his body, drinking in his awkwardly adolescent frame. He was an early bloomer for a boy. His cracking voice and the three scraggly hairs on his chin made him the very avatar of middle school masculinity.

Her heart beat in her throat. She licked her lips, now completely distracted from… whatever it was that he'd just said. She couldn't put it into words but he looked pretty good in a way she'd never noticed before.

He swallowed nervously, pushing up his square frame glasses. "Uh, so… do you want to be partners?" he reiterated, trying to weather her strange, silent gawking.

She blinked, attempting to chase away the hormonal noise buzzing in her head and between her legs. "Um, y-yeah," she sputtered, a little more emphatically than she'd intended, not quite understanding why this prospect felt so exciting beyond the realm of scholastics. "We can just go over to my house after school if you're free," she suggested breathlessly.

His eyebrows shot up. "You mean your castle?"

"Yeah, why?"

"Nuh- nothing. That sounds great," he replied, failing to temper both his anticipation and his trepidation. - - -

Crash Cart waited patiently as a stern looking castle guard rifled through his saddlebag. He smiled timidly, trying to lighten the mood and appear non threatening.

"Sorry, it's not my rule," grumbled Remedy, fighting the urge to rub her posterior on the corner of the nearby railing. It felt like MagiColt time again. Luckily it was quite flexible and could fit discreetly in the big compartment of her pack so she didn't have to freak out her companion with it.

"Background's good," came a disembodied voice from inside the post.

"You're clear," grunted the guard. He slapped an admission bracelet on Crash's forehoof before he loaded up with his saddlebag once more. Then Remedy teleported them straight into the throne room without warning.

"Mom?" she called. In front of Crash, Grandma was mom and mom was sister but Flurry Heart was busy in town for the day and wasn't in the castle.

Shining and Cadance sat side by side in their respective thrones in the middle of an audience with an ordinary looking crystal mare. Thankfully Shining was the one addressing the visitor at the moment. Their eyes flicked over at the intrusion momentarily but the discourse did not falter.

Cadance turned to Remedy and whispered. "Honey, you know you need to wait before just barging in here and talking while we're having meetings. What is it?"

"Ugh, sorry. Do you have any more of the… herbal tea." The stuff seemed to take the edge off of her heat but she wondered if it wasn't just ultimately a placebo.

"Yes, we do," she answered. Her train of thought was derailed as her eyes landed on the bundle of nerves that was Crash, standing beside her. "Oh, who's your friend?"

"This is Crash Cart. We're doing a science project together; that's why I brought him over."

"Oh, so you're Crash. Remedy has spoken about you before. Welcome to the castle."

"He- hello, your majesty," he quivered before bowing woodenly.

Cadance stifled a giggle. Science project, she thought. For a moment, her mind had entertained the thought that perhaps she'd brought home a coltfriend. It wouldn't surprise her at all if he was her type.

Cadance's eyebrows suddenly shot up in explosive intrigue. Wait a minute, this gangly dork was the answer to her prayers. He could be the one to ice Remedy's heat.

After four days, she was running out of time and ways to divert Remedy's discomfort and the frustration in the castle was palpable. Facilitating a sexual encounter between her granddaughter and a colt in her class wasn't something she'd ever consider doing under normal circumstances but it was an infinitely more preferable solution than her getting a prescription dose of Shining's dick. Anything to prevent her from falling permanently into her husband's debaucherous orbit and ending up like Flurry Heart.

Cadance quickly examined the boy's aura. He has a crush, she thought. How cute. Oh… a not entirely chaste crush either. Well, he is the right age for impure thoughts. It was all she could do to keep her evil grin on the inside.

Crash didn't strike her as the most confident or assertive of colts but she just needed to give him a little push and then nature would take its course. Remedy was already horny as shit and smelled like a coed dorm room on a Saturday night; if she just came at him under the right circumstances, how could he resist?

"I'm sorry, did you want some more of the tea?"

"Yes, please," nodded Remedy, trying to be on best behavior in front of subjects.

"Okay, just go to your room," she smirked. "I'll get you that tea. Have fun."

Remedy nodded again in concurrence before teleporting the two of them away.

This would be easy, Cadance grinned to herself.

The meeting ended and Shining turned to her. "What was that?" he asked in alarm.

"What was what?"

"That colt with Remedy," he clarified urgently.

"Nothing," she shrugged disingenuously. "Just her science project partner. They're doing a science project together."

His eyes narrowed. "Oh, really? The old 'science project' trick," he grumbled.

Cadance pursed her lips. "Well, I think you have everything under control here. I'm just gonna duck out and go see if they need any help."

"Wait, what exactly are you-"

Cadance vanished from her seat in a flash of magic before he could finish. His eyes darted ahead where he saw the next visitor stopping before the throne with a bow.

Remedy brought Crash to her room where they shrugged off their packs. The colt looked around and began to sweat as the reality hit that he was alone with a princess in her boudoir. The experience was all happening so fast with a distinct breach of royal etiquette that felt both taboo and intentional.

The alicorn scratched her head in bewilderment. What was the assignment again? Something… science… trifold… What was happening? Keeping her thoughts on school was never this difficult. It was as if her body were screaming over her brain to do… something. She'd become more physically and mentally agitated the moment he asked to be her partner and stepping into the bedroom with him had just made her whole body an angry hornets' nest. She looked back at the colt who stood still, afraid to touch anything.

Remedy floated her big personal notebook from her desk and walked slowly toward him. "I've been thinking about this for a long time."

Crash's eyes ping-ponged as he tried to supply context to the remark.

She cracked open the book to her hypothesis and levitated it up between their faces to show him. "My idea for the project is to investigate the changes to the local ecosystem following the resurgence of ponies in the area. I want to see if we can pinpoint the appearance of every species and make a corresponding timeline of events that likely spurred their introduction to the area."

He skimmed her notes and little drawings, mouth open as he ruminated on her proposal. "Wow… I really love that idea," he replied earnestly. "And your hoofwriting." He winced himself for saying the last part out loud.

Remedy let the book dip slightly so that she could see him over the brim. They locked eyes and froze as the lit fuse inside her burned all the way down. Her magic aura vanished from the tome, letting it drop to the floor and she lunged.

Crash's eyes bulged as the princess passionately pushed her lips to his muzzle. He fell back a half step but soon leaned into her with equal hunger.

Shining listened to about half of the pony's story before agreeing with the whole thing and then giving him the brush-off. "Um, audiences are over for today," he blurted to the advisor, clapping his hooves together. Then he too teleported from the throne without waiting for a response.

Remedy moaned inside the breathless wrestling of their clumsy, soaked lips, her intimate vocalizations sending shivers through her partner's body. Their forehooves pawed at each others' withers as their passion intensified. They had no idea what they were doing but it was instinctual and it felt like a rollercoaster.

Truth be told, he had imagined himself inside her a time or two but he'd relegated anything like this to the realm of nocturnal fantasies and honestly thought the most he'd be getting today was a smile and a solid science project idea.

His lips tingled. Everything tingled. His thoughts had become as hazy as the fog Remedy was leaving on his glasses. Harnessing every remaining atom of critical thinking power that Crash still possessed, he pulled out of the kiss and held up a hoof between them. "Ha- hold on," he gasped. Isn't your mom coming imminently with tea or something?"

"Ugh. Yeah," she groaned in dismay. How did she forget that? She checked to see if her pigtails were still intact. She wanted more, a lot more. On the plus side though, he gave her a 'hold on' and not a 'no.'

Suddenly there came a knock at the door followed almost immediately by the door opening, the telltale decorum of someone entertaining the illusion of privacy.

The two foals flinched away from each other as a shifty-eyed Shining Armor filled the door frame.

"Hey, Remedy," he began in an even tone. "Can you please go clean up your resin casting project before you get into your schoolwork?"

Her eyes fell to the floor. "Oh, yeah. I forgot. Ugh. Be back in a minute." Remedy blinked out of the room leaving Crash alone with the prince.

Shining beheld the on edge colt. He certainly looked like a shrimp but that was no reason to discount him as a threat to his daughter's virtue and good name. Shining broke the standoff by smiling genially. "So you're Remedy's project partner. What's your name?"

"Crash Cart," he replied, immediately proud that the name didn't die in his throat.

Shining put a hoof to his chin in thought. "Oh, like in a hospital?"

"Yeah."

"So what exactly do you want to be when you get out of school?"

"Paramedic," he grinned.

Did this kid even have the fortitude for a messy job like that, he briefly wondered. But if it was in the cards, it was in the cards, he supposed. "Oh, that's cool. Saving ponies… So you know mouth to mouth yet?"

Crash swallowed. "Well, I mean… heh. That part's not actually as important as the- the chest compressions."

Shining nodded slowly. "It's nice to meet you, Crash. And I'm so pleased to see that you're an upstanding young stallion and not some skeezy degenerate looking for fun in the wrong places." He punctuated with a good natured chuckle before sighing and leaning against the door frame. "I'm sure you know… the types who don't know their place or mind their manners or might even try something untoward with an afflicted young mare. Some ponies, I tell ya. It'd be silly to try something like that in a place crawling with security though. His eyes darkened. "And in a sprawling complex where somepony who's lost their way could easily go missing… you know?"

Crash felt his guts squish into his legs. He laughed nervously, not knowing what to say, fumbling for any words that could help take the heat off of him. "Well, you don't have to worry about me because I'm gay."

It felt like they'd both been sucked into the endless silent vacuum of outer space as neither of them could find the escape hatch to the next part of the conversation.

Crash maintained a weak smile but was punching himself in the face internally. Why did I say that? I want to die.

Shining's eyes narrowed disdainfully. So, the old 'I'm gay' trick. He's very crafty for his age. I do not like this one at all.

"Dad, you're still here?" asked Remedy, blinking back into the room.

"Yes, why?" he laughed with sudden jollity. "Are you anxious for me to leave for some reason?"

Instead of delegating the task to a servant, Cadance took matters into her own hooves. She decided to put birth control in the tea to make sure that Remedy got it no matter what happened but she'd also make the birth control readily available by choice in case they were hesitant to have sex, thinking that they didn't have any. Cover all the bases. She sprinkled a powdered aphrodisiac on their plate of brownies. It probably wouldn't do much for Remedy who already had a full head of steam going but it would work on Crash. It would be the perfect sexual powder keg.

Cadance teleported with her laced treats to just outside of Remedy's door. She knocked and then waited several seconds in case they were already doing something amorous and needed time to untangle. She opened the door slowly to find nopony inside.

Cadance frowned. "I told them to wait here," she muttered to herself. Maybe they'd already snuck off together somewhere, she hoped. Well, if they were already going at it, she definitely didn't want to interrupt. She decided to look for them but only in large rooms more likely to be populated with castle staff.

She teleported to the library which they could certainly still do it in but with unnecessary risk. She checked the dining hall where they were nowhere to be found and then the gallery. She appeared on the balcony of the southeast crystal spire and finally spotted them at a cluttered table in the courtyard below, surrounded by busy castle landscapers.

"Ugh… They can't fuck there," she groaned. "It's fine. It's fine. You'll get them. It's a slam dunk for the Princess of Love." She teleported down to their table.

"Oh, here you are," she began in dismay. "Here's your tea, Remedy." She set down the cup and saucer, next to her open notes with the poise of a veteran waitress. "And I brought a plate of brownies for you two." She set the pile on the table between the foals and smiled expectantly.

"Ooh, after I finish," said Remedy. "They taste gross with the tea."

Crash looked at the plate with initial interest but paused. "Are these chocolate?" he asked with worry.

"Double chocolate," added Cadance emphatically.

"I'm actually allergic to chocolate but I can have carob brownies if you have those. No one ever does," he muttered under his breath.

She scooted the plate away. "Oh, how thoughtless of me. I'll just go get you something else. Any other allergies?"

"Peanuts," he replied.

"No chocolate, no peanuts," she repeated.

He nodded. "Thank you, Mrs… Princess." Crash scrunched up his face in a pained grimace of mortified self loathing.

He's adorable, thought Cadance. I almost regret the birth control.

"I'm sorry," he groaned.

"You can call me 'Mrs. Princess' if you want," she laughed. "Oh, but you should really be in a room. Why did you come out here?"

Remedy sipped her floating tea. "Dad said we're not allowed in my room or other closed rooms. I don't think he likes Crash either."

"Oh, ridiculous," growled Cadance, looking around. She quickly found Shining's horn poking out from behind a well manicured hedgerow. Predictable.

"I'm going to have a talk with him. It's much too noisy and chaotic to work out here. You should either be in your room with the door shut, outside behind the groundskeeping shed or vanished into some other mysterious isolated room. Why, there's any number of nooks and crannies in the castle that no one ever goes, places where you could spend hours in complete solitude without anyone ever bothering you and have all the se- studying you want… to do." She cocked her head with an awkward smile. Nice save, Cadance, she thought to herself.

"Go ahead and pick anywhere," she prodded. "He'll never even know. I'll see you later." That was a good noncommittal, I'm not going to come drop in on you anytime soon kind of reply, she decided. She teleported away behind the bushes.

Shining screamed with a start, nearly dropping his binoculars.

"Shining, did you threaten that poor boy?" she hissed.

"What?" he blurted aghast. "No. No… Cadance, seriously? I simply- I just laid down a few guidelines on how we do things with boys over because we are in uncharted territory here."

"It wouldn't be 'uncharted territory' if your parenting style wasn't just suffocating caudling and vagina panic."

"That's not true," gasped Shining indignantly. "I just want to make sure she keeps her dignity and respect through all of this."

"Uh-huh," grunted Cadance, rolling her eyes.

"Where did they go?" he gasped, looking back at the now empty table.

"Wouldn't you like to know," she huffed smugly.

He glared suspiciously at her. "Are you trying to get Remedy laid?"

Now it was Cadance's turn to feign indignation. "What? Absolutely not! What kind of sick grandparent would even think about doing that? I can't believe you'd suggest such a thing."

Crash unbuckled his saddlebag to find a third vial of blue liquid clearly labeled 'female use birth control' in somepony's incongruously very elegant hoofwriting. There seemed to be one in every compartment somehow.

He scratched his head "These weren't there when I-" He abruptly shoved his pack away as Remedy approached him from her search of the wine cellar. Her hollow eyes luminesed in the blue light of the enchanted sconces.

Crash bit his lip with uncertainty. "So, are we still doing work or are we…" He realized it was a stupid question even before she pressed her lips to his and began devouring his mouth.

They stood on their hind legs as their bodies came together like magnets. Crash fell over backwards flat on the cold stone floor, his science project partner landing on top of him. The wind was knocked out of him for a moment but their feverish kissing never wavered. Her tongue shot into his mouth and he greeted it with his own. Little muffled sounds of pleasure echoed down the hall of giant casks in the converted cave beneath the castle.

They sucked and nibbled any tender piece of the other that presented itself. It didn't matter that they were amateurishly bumping their teeth together and smearing saliva on each other's muzzles. It was the most exhilarating feeling they'd ever felt.

Crash's trembling hooves traveled down Remedy's body to rest on her chubby flanks. The feel of her meaty backside in his grip was absolute electricity and his growing hard on filled to capacity with almost painful instantaneousness. Her hips began to gyrate, furiously humping and grinding his hard cock between their undulating bellies. The new feeling compelled him to move his own hips and rub back against her.

Crash gasped. Everything, all at once, the breathlessness even while they shared the same air, two hearts beating out of their chests, the tingling and tugging on his lips, her healthy ass like putty in his hooves while her angelic downy underside massaged his shaft. He was in free fall. It was all too new and too much for his inexperienced brain to process. He could feel the tension building in his loins like an avalanche.

Not yet. He had to find out what pussy felt like. Now that he was suddenly here on the precipice, he wanted to be greedy. He wanted to lay claim to an alicorn princess. No one would ever believe him. He had to pause. He had to hold out. But what they were already doing felt so good too. Maybe if he could just scoot the tip in. He stopped his thrusting but there was no slowing his runaway train.

Crash sighed with heavenly relief into Remedy's open mouth. He squeezed her flanks and shuddered as a hot geyser erupted between them. He felt his cock throb against her as a pleasant, slippery warmth spread across their bodies. Remedy continued kissing and grinding for several moments, only pulling off of the boy's lips when he seemed to lose stamina and the strange sensation became impossible to ignore.

Remedy sat up on him in slack jawed surprise. She looked down her body, rubbing her barrel curiously with both hooves, eliciting a quiet squish.

Crash panted, adjusting his glasses that had been knocked askew by their desperate entanglement. He looked up to see his science partner slathered and glistening in his cum. He couldn't quantify how intensely erotic she looked in that moment and even though he was spent, briefly wondered how the sight didn't immediately resurrect his softening member.

"Woah," she panted with heaving chest. "Is this your… ejaculate?"

"Uh, yeah," he blushed. "Sorry?"

She scraped a bit of it onto one hoof to examine it closer. "I see," she murmured. She sniffed her hoof, detecting a pungent salty musk that was alien but strangely alluring. Her wonderment gave way to fear, snapping her from her lust-addled spell as she gazed down at him. He was just as covered as she was. She wasn't exactly sure what was normal but this seemed like a lot for one colt to produce, like it had been building up ever since he hit puberty.

The fur of both their undersides was matted with cloudy white seed that they'd smeared on one another in their furious make out session.

In his post orgasm clarity, Crash understood that Shining Armor could theoretically appear out of thin air at any moment and the thought terrified him beyond words.

Remedy stood up and tried to smooth down her mane with her wingtips instead of her cum drenched hooves. Though riled up and unfulfilled, she knew she had to put her sexual awakening slash research on hiatus. "We'll be in trouble if anyone sees us covered in semen," she murmured. "They'll know what we did. We need to go wash ourselves off."

There were plenty of unoccupied guest rooms with showers.

They washed up separately and dried off. They got their project materials together. They nailed down the scope and did a bit of preliminary research out in the open and behaved themselves. They didn't talk about what they did, not with eachother, not with anyone. What they did was simply something odd that happened, a hiccup that neither needed to mention again that day, even as the echoes reverberated in the solitude of their own heads. There was a mutual unshakable feeling that the whole world had changed somehow or perhaps they had simply peeked behind its curtain, a shroud that they'd never even noticed before.

They never came to an understanding about what, if anything, their heated collision meant for them. Did she like him the same way he liked her or was it just mother nature pushing her toward the closest y-chromosome? In the end, they did agree that the school library would be a better place to work next time. It was less complicated.

Cadance sighed and waved from the balcony rail as she watched the two foals part. Remedy's aura was still haywire with undirected hormonal lust. She was clearly still in the throes of estrus. She giftwrapped it for them and they still didn't do it. Strangely though, Crash Cart's Aura had settled. That was odd, she thought. Usually that meant… Her eyes squinted in wonder. Could he have… missed his target?

The sound of labored breathing emanated from over Cadance's shoulder.

"Hey, Cay, do you have time to help me out with something?"

She turned around to see her husband gesturing under his barrel with one hoof.

Cadance's eyes followed to find his overstuffed cock, looking like it could fuck a hole in a brick wall. His tip was weeping with precum. She looked back up at him, noticing his face was flush, almost feverish. "Did you by chance eat a plate of mysterious brownies?" she droned.

Shining paused before answering. "Well, not the whole thing… Okay, yes, the whole thing," he admitted quietly. "Please," he whined. "It hasn't been like this since I was twenty. It feels like it's going to explode and not in the good way."

Cadance sighed. She was still annoyed with him but also chomping at the bit for his attention. "Come here, you big idiot," she ordered, masking her desire with a bit of theatrical derision. - - -

In the evening, Shining Armor updated Flurry with the day's events and she took it upon herself to speak with the filly in her room about how her heat was playing out. Things seemed to be coming to a head and they needed to intervene before she did something rash.

"My grades will begin to suffer if this doesn't get better soon," Remedy almost cried on the edge of her bed.

Flurry scooted up closer to her and wrapped her in a comforting side hug. "I know. I know. Hey, you want to know what I did to get through my first heat?"

"Yes."

"It was really bad, just like yours and I couldn't stand it anymore either. So you know what I did?"

"What?"

"I let Grandpa Shining rut me and it cleared up immediately."

Remedy blinked, scarcely believing what her mother was saying. "But that's… incest."

Flurry gritted her teeth. "Technically… yes but you can make exceptions in cases like this."

"But, any biological male will do. Why resort to incest?"

"Well, many reasons, actually. When it's your first time, it can be kind of scary and confusing so it's best to be with someone who you're very comfortable with. And If you're a very curious filly who has a lot of questions about anatomy and the reproductive process and things that you just can't get from books, it's nice to have somepony who's patient and knowledgeable. I know grandpa would agree to calm your heat too if that was something you wanted and he makes it really fun and easy."

Flurry almost drooled, thinking back to the very memorable mind-blowing oral her dad had lavished her with that night.

Remedy hadn't expected her mother's anecdote to end abruptly with an invitation for her to have sex with her grandpa. She scratched her head. The proposal sounded strange on its face, the age difference, the blood relation, but if her mom did it and was suggesting it to her now, it must have been… fine. Ponies did many things in the field of medicine that would seem strange or obscene in any other context. She just needed to approach the idea from a clinical standpoint. That seemed easy enough.

She gestated on it for a moment more, trying to envision real sex happening to her. Her face began to heat up. It would be nice to embark on such a journey with someone comfortable like grandpa who would be approachable with questions and open to experimentation. Now that she thought about it, sex under controlled laboratory conditions where she couldn't get in trouble sounded amazing.

"It wouldn't be for reproduction, of course," clarified Remedy.

Flurry smiled. "No, you would be using birth control to prevent that… just like I did."

The filly nodded, still thinking. Getting rid of her heat was a huge selling point but it was actually a secondary consideration now to finally being able to experience the rite of reproduction on all her own terms, or at least go through the motions. That sounded truly edifying. "Okay, that sounds good to me. When can I start?"

Flurry was internally on cloud nine at her daughter's decision. She wished she could do it right now but from what she'd heard about her mother's detonation of her dad's priapism earlier, he probably needed a little break to at least refill his semen reservoir. There was no such thing as too much semen, after all.

Flurry tousled her daughter's mane with playful anticipation. "I think tomorrow night would work well," she suggested with a twinkle in her eye. "But before then there are a few things we should go over first."

"Yes," nodded Remedy. "Let me just get my notebook."

Ask your doctor if incest is right for you.
