Twilight Sparkle couldn’t sleep. Primarily because the stars seemed off.

Ever since Luna’s return, she had taken the time every night she could to study the stars more in-depth than ever before. She thought it would be a good way to help the Princess of the Night feel welcomed home. Eventually, it had become part of her routine. So ingrained was it into her routine that if she didn’t get a chance to stargaze before sleeping, sleep tended to be either fitful or elusive.

So, Twilight had contented herself with staring up at the moon and the stars while standing on the balcony outside of her room. She could still the quiet lights of Ponyville and her school beneath her, like a reflection of the stars above. She wasn’t sure if she ever told Luna about that little similarity. She should do that sometime.

In fact, ever since Luna had left, her mind kept drifting to the Princess of the Night. In fact, she wondered what Luna was doing right now.

Her eyes were drifting through the constellation Andromeda when the moon exploded.

Well, ‘exploded’ might be a bit much. But that’s what it like.

A massive eruption of magical energy blasted out from the moon in a shockwave that bathed the countryside in shimmering blue light, like auroras in miniature. She gaped openly and stared up at the sky. Starlight all but rained down upon the world as the moon shone nearly as bright as a noonday sun.

She opened her mouth to yell for Spike when the castle trembled. She froze and looked around, trying to determine the source of the strange tremor. However, a few moments later, the strange blue auroras caught her attention once more as they reached the castle.

The entire structure ignited with incandescent white light as if the crystal had metamorphosed into moonlight made solid.

Including the balcony she stood on.

Twilight yelped and tried to take to the air, but despite her flapping, she could not gain even a single inch of altitude. Panic filled her.

“What in Equestria is going on?!” she demanded of the universe in general.

The universe responded when the blue auroras washed over her.

In a second, her worries and fears were gone. Strangely familiar magic washed down her horn, then into her horn. The magic continued through her, both inside and out, working slowly down her body. She shivered as it caressed places reserved for her fingers on lonely nights. She couldn’t stop a tiny little moan as heat rushed over her body in response.

Then, the magic grounded into the castle itself. The glowing castle of crystalline moonlight responded.

And it responded rather… intensely.

A stream of magic erupted directly beneath her and shot directly into her most private place. Twilight squealed loud enough to be heard in Canterlot as her panties instantly became half-soaked. She jumped high into the air, only to come crashing back down hard. However, she didn’t notice the impact or the vibrant stars above, since she was too busy thrashing to what was likely the most intense climax she’d ever had in her entire life. It had been a direct result of her castle interacting with magic, but right then, she couldn’t care less. She just let her hands run free, teasing and playing with her body through her dress—which was becoming rapidly disheveled.

As the moonlight effect on the castle faded, so did the orgasms. Eventually, only a few strands of light remained in the structure, most of them around Twilight. As for Twilight herself, she lay there in the cool night air panting as minutes slipped by without her caring in the least.

Eventually, however, curiosity overrode the afterglow and she pushed herself into a sitting position and looked around.

“Oh… what in Celestia’s name was that?!” Twilight demanded to no one in particular. Then, with another glance around and a blush, she mumbled, “Because I want another, please…”

The sensual nature of the pony body was one particular field she had spent little time researching. Of course, she knew the mechanics. Everypony knew those. Moondancer and her had been enjoyed several educational evenings together, once upon a time. And of course, there was the occasional tryst with one of her other friends. Still, the subject hadn’t ever been a major focus. After all, for it to become a major focus for her either required a very open relationship with a very understanding pony or to actually try a… romantic relationship. That, frankly, freaked her out.

Still, it didn’t stop her from fingering herself into a screaming mess every Saturday night.

“Focus, Twilight!” she snapped at herself, shaking her head.

She shouldn’t be thinking about this! She needed to determine the origin of that oddly familiar magical burst. Though considering the source, a strange connection developed in her mind as she finally recognized where she’d felt something akin to it before.

It had been when she’d used that bizarre potion to look back into the past and witness Luna’s transformation into Nightmare Moon. She’d never told her friends that she’d felt the magic Luna had used. But this almost seemed like… the inverse of that horrible moment.

Did this perhaps have something to do with Luna? Had something happened to her? She was supposed to be safe back in Canterlot! Twilight would never forgive herself if something had happened to her right after leaving her castle! She’d seen how upset Luna had been and she’d been helpless to render any real assistance other than a friendly ear!

Why couldn’t she—

“Twilight?”

The voice came from behind her.

Twilight spun on a heel and peered into her bedroom. To her shock, Princess Luna herself was sitting at the edge of the bed, looking down at the floor with her hands clasped before her. Her ears were back and her wings rustled slightly. She seemed… oddly nervous.

Yet, when Twilight looked beyond the body posture, she saw something that surprised her far more. The stars in her mane and tail were as brilliant as the ones above Twilight’s head. Beyond that though, Luna seemed… different somehow. Not just in body, but in magic, too.

Something had changed.

Twilight took a few tentative steps forward until she leaned against the doorframe. “Princess?”

Luna twitched and scowled. “No.”

“No?” Twilight felt a knot of fear form in her stomach and she stretched her wings slightly. “No, what?”

Luna turned her head and met Twilight’s eyes. Twilight could have sworn she saw comets glittering in the depths of that beautiful blue gaze. “No more of that. Titles divide us. I would ask you to no longer call me that, Twilight.”

“You… don’t want me to call you ‘Princess’ anymore?”

“Not unless strictly necessary.” Luna waved a hand. “You do not ask your friends to call you Princess, do you?”

“Well, of course not, but—”

“Am I to be counted among your friends?” Luna asked pointedly, her wings twitching again.

Twilight reeled a little, trying to figure out what in the world had gotten into Luna. “Of course you are!”

“Then I ask you to simply call me Luna.”

Twilight’s wings folded against her back as she studied the Princess of the Night—Luna. She looked almost ready to beg! This mattered to her, more than Twilight could possibly understand. Yet, there was a strange bashful air around the elder alicorn. Twilight just wished she knew why!

“That… might take some getting used to,” Twilight hedged.

Luna smiled, her eyes sparkling. “I’m willing to wait.”

Twilight scratched her head. There was something in Luna’s expression. Fondness? More? Oh, she still was terrible at reading Luna, though she could still read her better than Celestia. And that wasn’t a very high bar. Perhaps it would be best to focus on more critical matters.

Twilight shook her head and pointed out at the brilliant moon and the glowing night sky. “Prin—Luna, what happened? I saw the moon and—”

“Ah yes. You will have to forgive me for that, Twilight,” Luna chuckled wryly, running a hand through her star-studded mane. “I should have realized there would be magical side effects.”

“Magical… magical side effects?” Twilight finally stepped into her bedroom, her eyes locked on Luna. “What are you talking about?”

Luna slowly rose to her feet. She stared at the wall for a few long seconds, taking several deep breathes. Then she turned and strode up to Twilight until they were little more than a foot apart. Twilight had to look up slightly at the taller princess, though Luna wasn’t exactly looming or anything like that. In fact, her expression seemed a mix between wary and fond. Again, Twilight felt the nagging idea that there was something different about Luna tonight.

“Yes, side effects.” Luna licked her lips. “It… well, on further thought, it could not have been avoided.”

“‘Could not have been avoided?!’” Twilight squawked as she pointed out the open door. “Prin—Luna! Every race with even a shred of magic is going to feel that! And they’re going to demand answers to know what just happened!”

“Then perhaps it is for the best.” Luna nodded, looking somewhat pleased with herself. “Yes. Yes, I think this shall be a good thing.”

“And how is this ‘for the best?’” Twilight demanded, bouncing up and down on her feet in annoyance. “How is this a ‘good thing?’ Luna! I’m the Princess of Friendship! I have at least one student for every one of Equestria’s allies! And you’re the Princess of the Moon! We’re both involved in this! I need to know! What did you do?!”

Twilight may have been yelling at this point, but Luna didn’t seem to be offended. In fact, she was covering her face with her hand… as if to hide her giggles!

“This is no laughing matter!” Twilight stomped a hoof on the floor. “I mean—”

“Twilight!” Luna cut her off with a smile—and a blush for some odd reason. “You seem so flustered. Is there something amiss?”

“Aside from the entire night sky looking like it had just stolen half of the sun’s light, my castle transmogrifying into moonlight and—” Twilight wisely cut herself off before she could mention the screaming orgasm. “No, everything’s just freaking fantastic! What happened tonight?!”

Luna’s smile deepened. “You have a new ally, Twilight Sparkle.”

This caught Twilight entirely off-guard. “I’m sorry, what?”

Without answering, Luna stepped past Twilight and looked out over the night sky with a happy little sigh. “Anypony who is ten or older remembers when my shadow once stained the moon. When my shadow vanished, I was unleashed to wreak havoc across the land. I started here. A simple village within striking range of my sister’s base of power in Canterlot. A simple village to frighten into submission. And they did grovel… save for one very specific mare.”

Luna leaned against the doorframe, then turned back to Twilight with a smile. “You stood up to me even then, in a small way. You were willing to identify me to all. And then, you had the audacity to bring forth your friends, bond with them and despite my best efforts, bring forth all six of the Elements of Harmony. And then, you struck me down.”

“I…” Twilight swallowed hard and took a few steps backward. “I didn’t do that to you. I did that to Nightmare Moon.”

“We are one and the same,” Luna replied, her smile growing even as she described her own downfall—after a fashion. “Though I appreciate you trying to spare my feelings. You need not do so. Because I would share them with you right now, as I promised I would.”

“Promised?”

Luna again didn’t answer Twilight, but instead met Twilight’s gaze. She took a long, deep breath and then spoke once more.

“All those years ago, Twilight, you saved me. You saved my mind, my body, my heart, and my soul. The shadows I called a thousand years ago had all but totally consumed my essence. Through the Elements of Harmony, you restored what I once had been. Yes, you stripped much of my inborn power, but I am glad of it, as I was once again myself. And on that day, that very singular day, I believe started to fall for you.”

Twilight froze as if she’d been hit by a petrification spell. Luna’s Modern Equestrian had to have failed her. She couldn’t have... No, of course not. Twilight smiled—even she could feel how awkward the smile was—and managed to get out a few words to convey her thoughts on the present situation.

“I’m sorry, what?”

They were not the most eloquent of thoughts.

Luna turned to glance out the doorway again, smiling at her night. “With every challenge you and your friends conquered, I started to see your potential, as my sister has. And while Celestia sees you as a mother would see her most brilliant of children, I see you in a starkly different light. Even after all you’ve gone through, even after you’ve ascended, gained a title, a castle, saved Equestria a dozen times over… you still stargaze before bed.”

“You… you knew?” Twilight squeaked, her eyes darting between the night and Luna. “I… ah… you actually knew?”

Luna sighed happily. “Yes. And I have never been able to speak of it to you until this moment. My decision earlier this evening allowed me to come here and say these things.”

“And… what decision was that?”

Luna suddenly seemed far taller, reminding her a little of Celestia in both bearing and attitude.

“This eve, I beseeched the light of the heavens and the heart of the land. I did this so you and your friends would have a new and powerful ally in your battles against the shadows that lurk on the edges of our world,” Luna declared, her voice serene as she stared down at Twilight. “There was but one thing required of me in return for that power.”

Twilight opened her mouth to ask, but Luna placed a delicate finger on her lips, silencing her.

“I had to confess that I am madly in love with you, Twilight Sparkle. “And I have been so for quite some time.”

Luna exhaled, as if she had been holding her breath even as she spoke. Stars exploded in her mane as her smile deepened. Her cheeks were a little red, but she looked relieved like an enormous weight had been lifted off her shoulders.

Twilight reflected that, okay, maybe Luna’s Modern Equestrian hadn’t failed her.

“Y-you’re… in… in love with me?” Twilight squeaked, suddenly very aware of just how close they were. And how warm she was. And how they were already in the bedroom. And—

“Madly. Please don’t omit that part,” Luna chastised her with a giggle.

“But… why?” Twilight demanded. “I’m just me! I’m just—”

“Everything we talked about this morning and just moments ago. Leader of the Bearers of Harmony. Conquerer of Tirek. She who helped defeat Discord, uncover Chrysalis, destroy Sombra—twice—and more. You helped reform Starlight Glimmer and Sunset Shimmer. Oh yes, and saved my very soul.”

Twilight gaped a few more times. It seemed like the thing to do. It was the only thing to do.

“I know this is sudden, dear Twilight,” Luna whispered, a hint of hesitation creeping into her voice. “And I am not going to demand you confess your own undying love this night. But my fear of rejection from you, a pony I admire in so many ways… it was in the way. I see now that it has been a burden I’ve carried for some time.”

Twilight blinked. Okay, apparently, Princess Luna, Princess of the Night, the Goddess of the Moon and the Stars, was in love with her.

That… that she couldn’t process yet. Soon. Maybe soon. Soonish. But not yet.

However, she did want to process that explosion. Magical explosions from celestial bodies were something she could deal with. Not confessions of love from one of the only two Elder Alicorns in existence.

“In the way of what?”

“I think I have teased you more than long enough.” Luna smile turned into a mischievous grin. “Still, if I am to show you, it should be away from prying eyes.”

“What do you—”

Luna’s horn lit up. Her magic wasn’t blue anymore.

It was a pale white, like gentle moonlight.

There was a brief flash, then the doors and windows of Twilight’s bedroom were simply gone. As if they’d never been. However, there was one other startling difference. Namely, the ceiling had vanished, leaving them open to the brilliant moon directly overhead set in a vibrant star-speckled sky.

“What… did… you do…?” Twilight whispered. The magic that Luna had just used so casually should have been impossible, even for an Elder Alicorn.

Luna waved a hand and gave her a knowing smile. “I simply altered the flow of core magic to your castle and requested it reshape itself for the evening, transposing this room with a room from one of your towers, remove the ceiling, create a distraction field around our view so no wandering pegasi see what is about to transpire and a few other minor things. Just… to make things comfortable.”

“This castle was grown out of a seed of the Tree of Harmony itself...” Twilight began but paused when she realized Luna’s horn was still glowing white. “And your magic color changed. That’s… is that a good thing?”

“A necessary thing,” Luna said with a shrug. “Now, to finally answer your question.”

With a casual wave of her head, Luna attached Twilight’s bed to the wall and teleported herself squarely into the center of Twilight’s circular bedchambers. Then, she looked up at the moon and smiled.

Her horn burned ever brighter as liquid light seemed to pour down from her horn, over her face and across her shoulders. Twilight could only gape as the magic flowing off Luna seemed to fill the world. She felt her body absorbing the excess power. It made her almost giddy. It seemed to interact with whatever strange effect had happened earlier, making her warmer by the second as she watched the unfolding spectacle.

The moonlight—with an odd rainbow sheen—flowed over Luna’s shoulders and down her arms, only to begin spill down Luna’s medium-sized breasts. Luna sighed within her suit of light as it continued to envelop her, slowly sliding down her fantastic hips, smooth rear and all the way down to her legs.

Then, nothing happened—save for there was now a shining figure of burning moonlight standing in Twilight’s bedroom. The silence became a little awkward, so Twilight raised a finger to ask a question.

Luna absorbed the light in a matter of moments.

Then, she opened her eyes and smiled at Twilight, but her eyes were brimming with beautiful glowing moonlight surrounded by a shimmering rainbow edge. Twilight took a step backward into a wall, but she couldn’t tear her eyes away. The magic pouring from Luna had increased by a factor of ten. This… this was the magic of a Goddess. Complete with a capital ‘G.’

“Oh… oh my…” Twilight squeaked.

Soft blue lines that reminded Twilight of ancient spellcasting marks grew on Luna’s muzzle and face. The Princess of the Night let out a soft moan as she started to grow in every sense of the word.

The first and most noticeable change was her height. While Luna had always been a bit taller than Twilight, within a few moments, she had grown by at least a foot and a half. With that new height, the rest of her proportions changed.

Her beautiful gown shifted and reshaped itself, oddly becoming quite a bit more revealing through her midriff, thighs, bust and sides—well, honestly, just about everywhere. The result was a cross between tribal pegasus warrior queen and ancient unicorn fertility goddesses. Her wings stretched, then the feathers each becoming a piece of the night sky, giving the effect of twin ethereal visions of night that simply held the shape of normal alicorn wings. Luna stretched her arms into the air and more blue lines wove across her body from the top down, creating intricate patterns of intense magic. Some patterns, Twilight knew, some, she didn’t.

And she suddenly wanted to know them all.

Finally, her bust, which had always been a little smaller than Twilight’s, swelled by to nearly double Luna’s original size. That was only a guess though, as Twilight was a terrible judge of those sorts of things. Luna’s hips and her rear quickly followed her chest’s example. There was one final surge as Luna’s body became as one with whatever force she had bonded to, and then the magic simply faded… leaving Twilight panting, flustered and far more excited than she could ever remember being.

Throughout the process, the waves of magic had coursed over Twilight. Only now did she realized they had driven her down a kneeling position, her horn acting like a grounding rod for the excess magic. She swayed slightly on the ground, staring up at the now tremendous vision of Luna.

A Luna who definitely was no mere princess.

A Luna who could only be a full Goddess.

Luna opened her glowing eyes as the light of her horn faded away. She blinked in shock when she saw Twilight on her knees.

“No, no, no!” Luna cried. She rushed over, every movement leaving a brief echo of moonlight.

Then, she took Twilight in her new magic, levitating her to a standing position. The feeling of Luna’s new magic around her was… beyond intense. Enough to make her squirm a little, but she did manage to gain her feet.

Twilight whimpered slightly as she looked up at the stunningly gorgeous Goddess that now graced her presence.

“Twilight, are you well?” Luna asked, gently running her hands along Twilight’s face and around the base of her horn. Twilight felt a gentle probe enter her magic, just enough to ensure her health, but even that felt more powerful than anything she’d ever felt from Celestia. “Twilight, please!”

Twilight finally blinked and looked Luna up and down—though it was quite a bit more up than she was used to. She found she didn’t mind.

“I’m… okay,” Twilight said, her voice cracking a little. “I just… wow. Oh, wow.”

“I see I overwhelmed you,” Luna said, taking a step back and blushing—which looked odd with the arcane marks across her cheeks. “Perhaps it was the transformation or… oh, the excess magic! That is what caused the explosion earlier, you know. Intense magical feedback. In hindsight, I may have sought too much, so I am discovering I tend to… well, leak.”

“It… was really both,” Twilight whispered, gawking outright to a point that Luna blushed even harder. “I’m sorry!”

“No, I do not mind… not… really,” Luna clasped her hands behind her back. Even though she had the body and presence of a Goddess, she reminded Twilight of nothing more than a nervous schoolfilly. “So… you asked a question…”

“And… you just had to admit that you were…” Twilight couldn’t finish the sentence. She still could barely believe it.

She could believe it even less now that Luna had the magical power of one of the ancient goddesses of myths. Or at least it felt like she had it. She found herself wondering if there were arcane marks all over her body, or just the visible parts.

“I had to admit I was in love with you, which is still very much true, Twilight,” Luna whispered as she gestured overhead and around them. “I had to be as true to myself as I could to be granted the power to do this. And my feelings for you were the one thing that was left for me to confront.”

“You… did this to protect Equestria?”

Luna hesitated, then bowed her head, unable to meet Twilight’s eyes. “I… I did it for many reasons. For my own feelings of helplessness. For my fear of you throwing yourself into danger without another spellcaster at your side. To protect ponies as I once did, only better. And… I… did it in hopes that you would enjoy it. I know your love of magic, Twilight Sparkle. I had hoped if I took this magic upon myself, you might see fit to let me… I mean allow me… to… uh… court you.”

Twilight blinked a few times. “I… court me? I’ve… I’ve never been courted before… Sun and Moon, I’ve only been on a handful of dates!”

And Luna still seemed like the nervous schoolfilly, trying to ask out her crush for the first time.

“You’re serious,” Twilight whispered. “You’re actually serious…”

“Yes, Twilight.”

“I… I don’t even know what to think. Or say. Or do!” Twilight cried, waving her hands in the air as panic started to overwhelm her. Her brain tried to process this data and just found it was nearly impossible.

Nearly.

“I will not force myself upon you—” Luna began but Twilight waved her into silence.

“I know you’re not going to do that!” Twilight snapped with a glare. “Seriously. I know you better than that! I’m just… how am I… how am I supposed to do this? I… dating, love and romantic relationships are not my areas of expertise!”

“What would Cadance say?” Luna asked quietly.

That froze Twilight. Because once upon a time, she had gone to Cadance for every time somepony had seemed attracted to her. Granted, it was rare, but it happened. And her answer had always been the same.

“That… there’s no harm in trying,” Twilight whispered, staring at her feet. “As long as I wanted to try.”

“Do you?” Luna asked, her voice just barely keeping together.

Twilight closed her eyes. She didn’t want to see Luna’s new body, only think about her voice. Her words. What she said and what she was saying now. But she couldn’t start this without the truth.

“Luna, I… I can’t say that I love you back.”

There was a small sigh. “I never asked you to say such a thing.”

“Let me finish…” Twilight mumbled, squeezing her eyes shut as all the myriad versions of Luna played across her mind. “I’m… I think I’m willing to… try?”

She deserved that much, at least.

Complete silence was her reply. Finally, Twilight looked up into Luna’s glowing eyes. There were tears in them.

“You are willing to try… with me?” Luna asked timidly. How a Goddess could be timid, Twilight wasn’t entirely sure, but Luna was doing it.

Twilight nodded, a blush running up her body and into her face. “If… that’s okay with…”

Luna snatched Twilight’s two hands and kissed them both. “That is all I ask for now.”

When Luna kissed Twilight’s hands, it sent shivers of intense magic running up her body. And as the former Bearer of the Element of Magic, she had a rather unique connection with magic. One that only a handful of ponies knew about. Namely, that one the most erotic things one could do to Twilight Sparkle was to imbue magic into her body, intentional or not.

She couldn’t help herself. Combined with the still lingering heat, she moaned softly.

Luna blinked in surprise and then, slowly, tentatively, kissed Twilight’s left hand again. Luna’s lips were a pale blue, the same color of the magical lines across her body. Another bolt of pure magic ran into Twilight and she let out another gasp, her knees becoming weak.

“This… pleases you?” Luna asked quietly.

“Y-yes…” Twilight whispered, shivering, her eyes half-closed. “P-please don’t… don’t stop… your new magic is… extremely intense.”

Luna leaned down and slowly kissed Twilight’s palm five times.

It was enough to make Twilight nearly collapse. She would have if Luna hadn’t caught her. Twilight blinked open her eyes and realized the two of them were mere inches away, with Luna stooped over to have caught her. She could feel the heat of Luna’s breath upon her lips. Twilight went rigid, staring at her.

“This… perhaps I should stop,” Luna whispered, though she made no move to let go. “I… you just agreed to court and… I do not want you to do anything unseemly…”

Twilight stared up at Luna. She saw the raw power of the stars, the moon and the bright places of the world in Luna’s face. But she also saw the princess she had helped become comfortable with herself on that Nightmare Night so long ago, the one she helped defeat the Tantabus with, the one who she called friend. They were all one and the same.

If this Luna had been nothing but power, then Twilight would have pulled away.

But this was the Luna she’d known for nine years. That Luna was worth the risk.

And if she were to be totally honest with herself, Twilight had never been more turned on by a pony in her entire life.

So, Twilight leaned forward and kissed Luna hard on the lips.
