The young Princess Flurry Heart wandered the familiar halls of the crystal castle, looking at the walls she knew would one day be hers to command. Or maybe she’d one day be given her own land as Princess Twilight had before her. Just weeks after getting her cutie mark, these were the thoughts that filled her head.

She was not alone though, as her two crystal pony guards followed close behind her, escorting her back to the central foyer where she had a visitor waiting.

“You know I don’t need an escort anymore. I’m an adult now.” She remarked as they passed row upon row of doors, leading to rooms she’d never been in.

“A cutie mark does not mean you are an adult.” The female guard proclaimed, the same as they had been doing ever since she was old enough to request to be on her own.

With a sigh, Flurry picked up her pace, a small act of rebellion that wouldn’t get her in trouble. She began to gallop through the halls, outpacing the fully armed guards as she dashed to the foyer. She extended her wings to propel her forward, beating her majestic wings carefully so as to not damage anything.

In a matter of moments, she outpaced the guards, leaving them a turn or two behind her, struggling to keep pace. However it was at that moment that she rounded the corner into the foyer, to meet the guests she had been summoned for.

“Flurry Heart!” The princess of magic shouted as she watched the entrance, waiting for her niece to arrive. She quickly moved forward and wrapped the speedy girl in a hug,“Look at how much you’ve grown. I can still remember when you were a baby foal, and now look at you.”

Flurry smiled as she was embraced by her aunt. “Hi Aunty Twily. How was the train ride up?”

“Oh, you know, the usual. Pretty quiet in the royal train car, perfect to get some reading done. A few ponies greeting me here and there. I’m sure you get stuff like that all the time.” Twilight released the smaller princess as they conversed. “Congratulations on the cutie mark, by the way. Your mom told me it was a love cutie mark, just like hers.”

“Heh, yep. Just like mommy’s.” Flurry heart giggled as she glanced back at the marking on her flank. It was a blue heart like the one her mom had, but lacked the crystal motifs. Instead, replacing it was a purple symbol that appeared to combine the gender symbols. Though she claimed it just appeared on her one night, its true nature wasn’t quite something she was willing to share with her aunt, or her parents for that matter. “One day, I’ll grow up to spread love, just like she does.”

“She started pretty young. Younger than you are, spreading magical love to others. You should have seen her and Shiny back then.”

“Back when what?” Princess Cadence asked as she and Shining Armor walked in, closely followed by the pair of guards assigned to escort the princess.

As Cadence and Twilight began their meeting ritual, greeting each other with the same rhyme they always did, Shining and the two guards confronted the young princess about her stunt. Shining, the prince and the guard captain, stood tall above his daughter as he spoke. Though he struck an intimidating pose, his voice was soft. “Sweetheart. You know why we have the guard for you, yes?”

Flurry didn’t look at her father, once again confronting her about her habits. As she groveled, she weakly responded, “To ruin all the fun.”

“No. To keep you safe.” Shining said in a very fatherly tone. “I know you’re a princess, but I don’t want anything bad happening to you. Even on castle grounds, who knows what could happen.”

“Nothing bad will happen daddy. Everyone loves us, there are dozens of guards already in the castle, and I’m a powerful princess. Nothing wrong will happen.” Flurry retorted as she tried to make herself look tall for her father, standing up to him.

Though the older unicorn did not fight back, instead lifting a hoof to gently pat the alicorn’s head. “Just accept the guards for now sweetie. When you’re in charge, you can do whatever you want.”

Flurry’s mood had soured from her father’s words, but they had aunt Twilight over. Now was not the time to fight.

The group rejoined the princesses as they enthusiastically wiggled their rumps in the air. Both princess Twilight and Princess Cadence lifted their tails, exposing their equine pussies to one another as they shook for one another, presenting their rears for all to see. Though the two guards politely looked away. Flurry watched as the two older mares presented themselves to one another. Meanwhile Shining had to avert his eyes to prevent his cock from falling out of its sheath, blushing profusely as he caught an intimate view of his sister and his wife.

The two lowered their rumps, then their tails once again covered their backsides, giggling with one another as they enthusiastically caught up with one another. Shining was quick to join in with them, filling one another in on all the details of their respective empires.

Flurry quietly listened as they talked politics and other topics that bored her. Though she found the affairs of citizens to be quite interesting, it seemed no one cared to talk about that as they talked about the bureaucracy and the high class. Flurry missed Aunty Twily’s tales of her exploits, how she had adventures and helped people while traveling all over equestria. Now it seemed like those days were far behind her, and with it were her stories.

Flurry was so bored that she barely noticed as her flank began to pulse. Her cutie mark shone as a ring of light pulsed from it, shedding a dim light into the room. She continued to nod along to political talk as it all rolled off her, in one ear and out the other. She kept nodding as the conversation slowed, and the others took notice of the young princess’ cutie mark.

“Flurry. Flurry? Can you hear me?” Twilight asked as she waxed a hoof in front of Flurry, breaking her out of her bored stupor.

“Huh, yes, chancellor rarity and her new clothing line. Yeah, yeah.” Flurry blurted out, not quite sure if they had moved on from that topic or not.

“No, no,” Flurry deflated as her mom corrected her, “Your cutie mark. It’s glowing.”

“Wait really?” Flurry said as she glanced back, confirming indeed, the blue heart on her rear was pulsing a dull white light. “What does that mean? Do all cutie marks do this?”

“Not all of them.” Twilight stepped in front of the filly before circling around her, examining her. “This only happens to special people, but I haven’t seen it in a decade. The friendship map is calling you somewhere, to solve a friendship problem.”

Flurry perked up at the mention of the map. “Wait, does this mean I’m gonna go on an adventure like you used to? All by myself?”

“Not all by yourself missy. You’ll have a detachment of guards-”

“Yep, all by yourself. No guards are necessary.” Twilight cut off her older brother as she gave him a harsh look. “The map is calling you, so you have to go.”

Shining gave her a dirty look right back, as the siblings wordlessly fought. “She’s my daughter, and I’m guard captain. She’s going with the guards.”

“I was actually called by the map before. I know what’s best.”

The two stood at a stand still until Cadence came to Twilight’s side. “I think we should listen to her. She is one of the elements of harmony after all.”

With Cadence’s support, Twilight gets Shining to back down, but he isn’t ready to give up. “If she’s not going with the guards, then I’ll go myself.”

“Shining, no. We just said-”

“I’m not gonna let my daughter go alone to who knows where all by herself.”

“The map isn’t calling you, it’s calling her.”

“If I’m not going, someone has to.” Shining and Twilight go back and forth with one another fighting about this as Flurry wordlessly watches from the sidelines. She didn’t want to go with her overbearing dad, especially if she was right about her working theory. If she remembered the stories right, the map called her for her talents, and she really didn’t want her dad finding out what her true talents were.

The two wordlessly squared off once again, fighting over who knew what was best, only to be interrupted by a dragon entering the foyer. Spike, Flurry’s favourite cousin, casually entered into the battleground, eating a gem dusted donut. He had really grown up over the past handful of years, standing as tall as almost any stallion. His dragon lineage gave him natural strength, but there was more to it than that. He still lacked his draconic wings, but his body was well defined. However what always caught Flurry’s attention were those emerald eyes, perched above his dragon snout. She could just get lost in those deep, emerald beauties.

“Hey everyone. Sorry I’m late. Did you know Donut Joe has a place out here? Best donuts in equestria. So, what did I… miss?” Spike started off enthusiastic, but lost his train of thought as he stood in the doorway, looking at the scene in front of him.

“Perfect. Spike can take her.” Twilight exclaims as she retreats from the battle, claiming victory. “He used to go with me on all my adventures, and he’s combat trained, better than any of your guards. He can breathe fire, and can send you updates about her progress.” Twilight smiles as she believes she’s solved everything.

Flurry was quick to agree with her, even before she really knew what she was saying. “Yep, Spike’s coming with me.”

Shining, not impressed, relented on the matter. Looking at his sister, his wife, and his daughter, the three of them were too much for him to fight against. He hung his head as his ears pressed down on his head, and he groaned. “Fine. Spike can take her, but I expect at least one message every day.”

“Come on Shiny. Don’t worry too much. She can take care of herself.” Cadence said as she sidled up to her disappointed husband. Leaning in, she lowered her voice as she continued. “And with Flurry and Spike out and Twilight visiting, we can try those things you’ve always wanted to do in the bedroom.”

This sentiment served to soften the Prince. His ears perked up as he knew what his wife was implying. He tried hard not to show what a strong argument this was. “Okay then. Spike can take her on whatever mission this is.”

Spike was left out of the loop, looking back and forth between the mares and Shining. Though he could guess at a few things, he was still confused about what was happening. “Uhhh… What?”

Twilight took the time to fully explain the situation to Spike, who continued to happily eat his donuts as everything happened. Once he understood what was happening, he quickly agreed to take Flurry wherever they needed to go, much to the young princess’ excitement. Then twilight cast a spell that opened a magical window to see what exactly the map said. Flurry’s blue heart cutie mark with the combined gender signs circled around a small village bordering yak territory. That would be the destination of Flurry’s first friendship mission.

With saddlebags packed and a companion at her side, Flurry Heart set out for the train station, with only a slight deviation to pick up some more donuts on the way.

As the train station was piled with people, very few took notice of the dragon and the Princess. Though dragons were still a sight, they were growing more common in pony territories with the help of queen Ember’s integration initiatives. And though the princess out of the castle would be noteworthy, the princess was still small enough to evade too much attention, especially if she didn’t use her wings or her horn.

The two greeted the Ticket seller, only to receive a simple smile, and two golden tickets to their destination. As well, a member of train security was dispatched to make sure Flurry got on safely. This only annoyed Flurry more as she realized she was in yet another escort.

Minutes later, their train pulled in with a royal car attached just before the caboose. That was what finally got people to take notice of the small princess, who was rushed into the cabin by the security member before it was swarmed with people wanting to meet the princess. Though Flurry wanted to greet them, the security pony insisted she not, not wanting to hold up the train.

She still went to the window and waved out to them as security began to corral the ponies back to the platform, and on to the train, if they had the ticket.

As the train pulled out of the station, Flurry finally began looking around the train car. It was certainly designed with royals in mind. It had luxurious red carpets with a golden trim, and ornate decorations all representing the crystal empire. The back had a bed large enough for four, while the front had austentatious seating for a dining experience. None of it had any modesty or restraint. It was easy to tell that it was her parent’s normal car, as there was a portrait of the two in a loving embrace hung opposite of the bed, while above the bed was a family portrait, done before Flurry could remember.

Spike sat across from her as she took in the sight of the car, looking from wall to wall, seeing everything she could. Spike cut in, as he slid his box of donuts on to the table, flipping it open for them both to enjoy. “Have you ever been on a train, Flurry?”

The princess let her eyes glaze over as she looked from spot to spot, no longer really taking in what she was seeing. “A few times. Usually on ‘royal business’ to canterlot.”

“Ahh, so trips you didn’t want to take.” Spike said as he grabbed a donut covered in gem flakes to enjoy.

Flurry kept looking around until her view met the window beside her. She watched as the flatlands around the empire gave way to the frozen landscape and snowy hills. “Maybe a little. My parents have also been pretty strict on me leaving the castle for a while, so getting out at all is pretty big for me.”

“Well, you know what’s pretty big for me? These donuts. Who knew Donut Joe’s recipe was so good on its own?” Spike joked as he took another bite out of the donut he held, eyeing up whatever he would eat next.

Flurry didn’t laugh though as she looked out of the window, looking longingly at the hills that quickly passed by.

Spike took notice and pushed the box of donuts towards her. “Hey, you’re thinking about something, aren’t you. What’s up?”

Flurry took a moment to think, not responding immediately as she collected her thoughts. Turning to the dragon, she looked into his deep green eyes. “Hey, you know you’re my favourite cousin, right?”

“I think I’m also your only cousin, unless Cadence has any sisters I should know about.” Spike continued to joke, hoping to lighten Flurry's mood.

And it worked, as Flurry let out a little giggle. “Come on, you know what I mean. We’re close. And if I tell you not to tell others about something, it will stay a secret, right?”

Spike took another bite of his donut, now almost completely gone as he looked at the princess. “Yeah, I won’t tell anyone. Pinkie promise.”

“Okay.” Flurry took a deep breath, fogging up the glass as she gazed out to the world. “Well, you know how Cadence said my cutie mark is about love?”

“It’s a cute little heart. What else could it be about.”

“It’s about sex.” Flurry blurted out. As she said it, she felt strange about everything. It was nice to have that out of the way, like a weight had been lifted off her shoulder she didn’t even know about.

Spike, however, was too stunned to speak. Partly from the bluntness of the statement, but also by the concept. This little princess was the princess of sex. Slowly, Spike came back to normal, squinting as he tried to look into Flurry’s bright cyan eyes, looking for anything to tell him it was a joke. “Flurry, you shouldn’t make jokes like that. I mean, you’re only fourteen. What if-”

“I’m not joking spike. My special talent is either rubbing my pussy, or it’s sex. And I’m not an expert at cutie marks or anything, but I think a pussy rubbing cutie mark would be pretty explicit.” Flurry spoke very franky about all of this, despite knowing how weird it was for her to say this.

Spike kept looking at the filly in front of him, looking to see any sense of a lie, but he didn’t. The young princess seemed genuine. “Well, then how did you get your cutie mark? Are you… You know, seeing anyone?” He was a bit nervous about the topic, since he was talking to his young cousin about her sexuality, but Flutty heart was more than willing to answer very bluntly.

“Well I was up late one night, reading one of the books from mommy’s private collection. I had a wing between my legs as I held the book with my hooves. I can’t concentrate on magic when I orgasm, and I don’t really like it when books fall on my face. I was getting close to finishing and-”

“Okay, I get it.” Spike cut her off before she could finish her story, “Okay, so you’re either the princess of masturbating, or the princess of sex.”

“Master-what?” Flurry innocently asked, despite the overwhelmingly lewd tone of the conversation up until that point.

“Wait. You’re the princess of sex, and you don’t know what masturbation is?” Spike asked the princess in such disbelief that he had to put down his donut to not risk it falling from his grip. “How much do you know about sex?”

“Just what mommy’s books say. Sex is something that is fun for mares and stallions to have fun with. Sometimes a mare puts a stallion’s penis in her mouth, and other times it’s in her pussy. What more is there?”

Spike just listened, astounded by how lewdly this filly was speaking. Though also astounding him was that, for the princess of sex, she didn’t know much about what she was princess of. “There’s a lot more. Like, way way more than just that.” Spike went to stand up to walk as he thought, but realized just how the current conversation was affecting him. He could feel his thick dragon cock standing at full attention, talking to his cousin about sex. He no longer tried to stand as he picked up his donut again.

The two sat in silence for a moment thinking about what to do now.

A light bulb suddenly went off in Flurry’s mind as a wide smile formed on her face. She excitedly turned to her draconic cousin and innocently asked. “Can you teach me about sex then?”

Spike choked on his donut as the innocent filly across from him asked him to do one of the most lewd things possible. “Ahem, excuse me princess? You want me, to teach you, about sex?”

“Yes.”

Spike’s hope of not exposing himself to the filly went out the window once she asked that. Still, he didn’t want to do anything she didn’t want. “Okay, teach you what?”

“I don’t know, everything? I’m sure you’ve been with a few girls. You’re uh…” For the first time, a blush began to form over her face as she quickly glanced up and down the dragon’s toned body, “You look good.”

Spike would have returned the blush if all his blood hadn’t rushed to his stiffening cock. He looked down, not able to look at the filly before him. “I uh… I have. I guess I can teach you a little. But not much.”

Flurry continued to smile as she magically grabbed one of the donuts and took a big bite out of it. She quickly gobbled it down before getting up from her seat and prancing to the bed in the back. She let her tail flag high, exposing her filly bits to the dragon as she moved. She looked back over her shoulder as she beckoned Spike to follow her “Come on. We have to be on the bed, right?”

Spike had to pry his eyes off of flurry’s light pink rear. The sight of her tight little pussy and her tighter, tasty-looking ponut was hard not to stare at. He yanked his head up to meet her eyes as he spoke. “O-okay. Lesson number one. There aren’t really any rules. You can uh, do it, anywhere you want.”

“Oh, they never said that in the books.” Flurry innocently says as she turns, making her way back to the ornamental chair across from Spike, “Then where should we start?”

Author's Note

Thanks for taking the time to read my story. This is something I wrote about a year ago but was never confident about posting. After some friends found it and told me it was good, I figured I'd share what I had. Likely some changes will be made before writing the next chapter, as I am rethinking how the problem will exist in this world.

Also, I never watched beyond season 7, so if I get anything wrong, too bad. Again, thanks for taking the time to read this.
