Luna and Celestia share strong feelings.

After her return, Luna is eager to talk to Celestia about her feelings. It has been ever so long. She finally has the chance to say what's been on her mind for a very long time.

Unfortunately Celestia is a bit preoccupied.

Gentle Night

Luna smiled in the cool autumn air and landed gracefully onto the balcony. The chill kept her alert, but she relaxed her muscles. Just breathing, letting the night wash away her anxieties.

Through the window Luna could see her sister's sweet white eyelids were shut, and her body was laid out on the plush mattress, hoof twitching once against the sheets.

The moment suddenly becoming real, Luna's instincts screamed. It was wrong! Was she not supposed to be so pure and good?

...But if not Luna, what mare could be worthy of the honor?

With a soft hum, her horn flickered with the moonlight. The balcony door quietly swung open.

Making sure not to trip or kick anything, Luna snuck across the room, excitement building with delicate hoof beats. There she was, close enough to taste!

Seeing Celestia so cozy, so naturally beautiful in her bed filled the night with joy. Along with it came the unnatural, frightening sensation, and the same awful feeling that had taken her so many years and a mountain of courage to overcome.

Swallowing against the burning in her throat, Luna stepped onto the bed, careful not to disturb the sleeping princess.

So close, and yet still so far. This close she could feel her sister's warmth, see her breathing, and if she really listened, Luna could hear her heart beating.

What was she dreaming about?

Surely a peek wouldn't hurt anything.

Closing her eyes and letting her most natural magic flow, Luna stepped into the realm of dreams. Into her precious sister's mind.

Luna's eyes flicked open as the world swam into view.

There was no sign of the solar princess, and the world was silent.

Luna peeked out a window. The moon was gone, and the night void of even stars. Not a good sign.

She pressed onward, eager to learn something. Anything.

The landscape of Celestia's mind was neat and orderly. This was pretty much what one would expect from in anypony working in government. Even so, the castle had no life. No pony but she roamed the halls.

Maybe that was because it was supposed to be night? Yet not even guards roamed the halls.

Clearly Celestia valued her privacy.

As her steps echoed back at her, Luna concluded that Canterlot castle was empty and cold. And she was all by herself.

As she lingered in the dream, her hooves felt numb. Just what was happening here? Was it a nightmare? Was her sister's dream simply that of peace and quiet?

A sharp crack echoed from down the hall. The chill of the castle turned to sudden heat.

"Tia?" She felt so small, her own fears intensifying. Galloping towards the sound, ahead of her a door erupted in fire and smashed into the opposite wall. A monstrous roar, a dragon!

The hallway was lit ablaze. Eyes wide, she turned the corner, charging straight into the now burning room.

White scales, bright pink eyes, furious with rage. Restrained by chains, unable to escape. A twisted perversion, but there she was. On a mockery of the Equestrian throne, the creature was leashed to it by heart shaped chains.

Was that how she saw herself?

The dragon was three times her size, but she felt no fear of its mere form. It was someone very dear to her.

"Is that you, my sister?" Luna asked, primarily to announce her presence.

At the sight of her, Celestia lashed out, strong draconic legs leaping into the air with jaws opened wide, ready to bite. Luna winced, but the impact never came.

Celestia's bonds held tight, and she recoiled to her prison's center. "Y-" Holding a claw to her throat, Celestia coughed and lowered her eyes.

"...You should leave." She growled, suddenly dismissive.

"Celestia!" Luna gasped. "You would attack your dearest sister? Why?" Worry sprung from every aspect of her being.

The dragon didn't answer, preferring instead to stare at one of the many piles of treasure.

Silence.

Feeling disconcerted, Luna studied the room. It was full of treasures. Molten porcelain ponies lay scattered, and it vaguely resembled the shape of Equestria. Plus some areas beyond their realms. Celestia's throne was in the center of it all, and on the ceiling rested the sun eclipsed with her moon. Not images of them, but the objects themselves.

A rare event indeed.

"You're better than this." Luna said, stepping forward. "This isn't you. you're not..." Shaking her head, Luna continued, her voice cold. "...One who haunts innocents and enemies only to see the world burn." She met her sister's fiery eyes.

The dragon stood, towering above her. Around them the room's fires continued to eat the room.

"You're kind, and caring. You do whatever it takes for the ponies you love." Luna glanced at the chains. "You may treasure them, and it might seem like a burden now and again, but this isn't you."

"I am nothing more than this!" Celestia asserted, stomping a claw in the ground, shaking the whole room. Those sharp horns shone, and the flames around them blazed brighter. "No one else has a full belly with silver stitched in opulence." Moving forward slowly, white claws strained her bonds, pulling her as close as she could to Luna with her constraints.

She'd seen it. Could feel the sun, so close to her coat, so close to her soul, and yet so different. Luna too drew closer, cautiously intrigued by the feeling.

"Sister..." Luna shook her head. "Dragons are lonely creatures. I know you've felt like one of a kind for so long-" She blinked, suddenly realizing. Looking down at herself, she found the answer: dragon claws where her hooves ought be.

"But do you really see me as a rival?" She asked, circling the throne, feeling the strange weight of her lizard body, meeting her sister's eyes again.

"Well, I'm not." Shaking her head, Luna shed the scales, becoming a pony once more.

She would play Celestia's game. But on her own terms. Luna's body turned metallic, reflecting the mixed moon and daylight. As easy as breathing, Luna was made of silver. Safe from draconic fire, she stepped forward towards the brooding dragon.

It didn't matter that Celestia had thrown herself into this dungeon of her own design. It didn't matter that she was lashing out. She was hurt, and this was to be put right.

There wasn’t a single barricade to hide behind. But she didn't need one. Not any more. There was nothing in her way.

"Sister, this place is warped by your emotions. I can see your obligations have worn hard on you the last millennium. There's no shame in that."

This was as close as she could possibly get to her, and yet her fair sister was still so far away. She watched as Celestia's scaled tail lashed against the floor.

"What binds you, dear sister? What heavy burden rests on your heart?" Luna's horn glowed bright, and a large spray of frost shot out from it. Chilling the room, flames withering. It was just them, and piles of treasure.

Celestia turned her head away, passions cooled. Eyes no longer of anger and rage. She started to shrink. "Can't you just, please... stop?" Celestia bit her lip, looking away.

"Sister, you always push me away." Luna continued, moving to meet her eyes. "I have to..." she started to say, but the words died in her throat.

Celestia's claws scratched at the ground as she crawled away, carving grooves in the rug. She couldn't even look. "Luna, please..."

Some of the chains weakened, and broke as Celestia's mighty form began to shrink.

Celestia turned the rest of her increasingly small body away, jaw clenching. Luna continued. "We can work through this." She urged, "You don't have to suffer alone anymore, it's going to be okay."

Luna took a step forward, and soon Celestia was smaller than her. No longer draconic, but increasingly fluffy. Long ears drooped from her head.

Luna shed her gemstone form, and crouched down beside Celestia. Who was still looking away.

Celestia collapsed, and started to cry. Her size stabilized, and she was a bunny.

A white and gold, adorable yet depressing bunny.

"Can't you just tell me?" Luna pleaded.

For lack of better ideas, Luna shrunk too, taking the form of a nightingale. She laid a wing across Celestia's body.

Celestia leaned against her, but remained silent.

Giving her the much needed space, Luna gently applied pressure, giving soft strokes.

Celestia sighed, looking up at her.

"Promise you won't laugh?" Celestia asked, finally accepting her sister's invitation to talk.

"Of course."

Kicking an adorable little bunny foot, Celestia sighed again.

"I don't get to make choices." Her tone was flat.

"What?" Luna said, her bird head tilting in an avian yet exaggerated way. "Sister, what do you mean?"

"I mean..." Celestia's bunny brow furrowed.

"I mean I have to always make the right choice. Do what is best for Equestria. For centuries at a time."

The blue nightingale considered this, stroking her sister all the while, gently. "How do you want to choose?" She asked after a moment's thought.

"I..." Celestia slumped into her, and went silent again.

"Or perhaps..." Luna reconsidered her question. She whispered in Celestia's ear. "Perhaps... you want to have no power with which to be unable to choose?"

"What?" Celestia asked, eyes wide. Luna only smiled a very birdy smile.

"What if I... just take over for a bit?" Luna grinned through her beak. "Let you be free- lets take you back to how we were all those years ago. Before you were Princess?"

Celestia tapped a bunny paw to her bunny face, considering.

"Okay." Her voice sounded hopeful for the first time that night.

With a sharp nod, their bodies grew, reforming. Celestia's equine form was fully returned, but not the one Equestria was familiar with. Instead of a alicorn, her body regrew into that of an adult unicorn mare in her prime.

This was her sister, Tia. Pink mane, firey personality. Lovely eyes. All the energy of her prime, with none of the bells and whistles that came with being a noble pony.

Sitting up, Tia examined herself. No larger than anypony else. Just an ordinary mare. She visibly relaxed, shoulders rolling, feeling free of their heavy burden of wings.

"Lulu~" Tia chimed, smiling at her, looking her over. All over. Luna's own body was returned to that of a pegasus. It had been so long...

They sat there, staring into each other. Just the two of them. It could have been thousands of years ago. As if nothing had changed. As if they'd just... made everything else up.

It felt like she could just... make up for lost time.

With a final act of bravery, Lulu leaned in slowly. Eyes closed and mouth opened wide, she pressed her lips to her sister's.

Soft. Gentle. Welcoming.

She felt her sister's head press against her in earnest, and it was then she learned that Tia had quite a long tongue.

Lulu could feel the intensity under her jaw, the trembling and shaking. She was lost in the trance of her sister, and the thought of her filled her with joy. She felt her tongue slip inside and out, and it tasted amazing. Luna moaned into it, enjoying every instant.

Lulu looked at Tia. She always knew she would be fine with it, but that it was actually happening...

"You seem to be enjoying yourself," Tia said, lips curling into a smirk.

Lulu blinked, looked away, and then clenched her teeth.

"I'm sorry, sister," she said, "I'm sorry. I really am...I just..."

"I always just wanted you to be happy," Lulu said, plainly. "I just never expected to be able to... well, go on a date with you..." She closed her eyes, feeling the tension in her body return. "And now that I am with you, I'm happy."

"Is that what this is? A date?" Tia giggled. "Can't say I fancy the location." She teased, looking around at the soot and ash.

Lulu was surprised by the sudden shift in mood. She was laughing? Turning back to face her, she saw Tia was smiling. She felt her heart soar. That prize-winning smile Tia shared with very few.

"I was a little surprised," Tia said, glowing ever warmer. Like sunshine, like the spring time.

"But only because I expected you to go for it all those years ago. What took you so long?" She poked Luna in the shoulder. "Have a little trouble working up the nerve?" she teased.

A little embarrassed, Lulu's eyes were sparkling as well. "Well. Maybe a few more years than I thought it would be..."

Celestia then continued the work on the nerve, her hooves pressing deeper against Luna's side, gently massaging. She shifted her weight inward.

Luna moaned as she felt her sister's tongue work into the back of her neck. Those soft lips pressed gently, kissing her all over.

"It's okay, Lulu. You have me," Tia purred, her horn glowing as she gently touched Lulu everywhere with magic.

"That..." Lulu began, trying to not seem like a wound up ball of pleasure, the touches making her blush and mumble. She tried to return the favor, planting her lips deep into those gorgeous white hooves and lovely pink mane.

The feathers of her left wing poked out of her left wing, extending out a bit down, to show they were close. Then, slowly, one stroke from a small nape of her neck to at the tip of her ear, then down her neck.

When she opened her eyes, Lulu was on top of her sister, hooves wrapped around. Taking a moment to stare down at her sister, she noticed Tia had finally relaxed.

"I'm ready if you wish." The words made the world stop. Lulu became motionless. She realized their teats were touching each other.

"Ready for...?" She swallowed and stuttered. She couldn't move and couldn't believe it. Eyes wide with anticipation.

"Oh Luna," her sister smiled teasingly "surely you don't enter a mare's dreams without hoping to become the mare of their dreams."

"You can't mean-" Lulu started, but Tia cut her off by leaning in. She set her mouth right new to her ear.

“Mmmm... fuck me.” She whispered, hind legs spreading. Lulu felt her lower half dropping between them. Solar excitement pungent in the air, wetness below her. It was everything she ever wanted.

LuLu couldn't help but feel the excitement too. Cautiously, she slid her sister's vaginal lips against her own.

Both of them continued hard kisses. Lulu's wings were still wrapped around Tia. Tia's tongue prodded at the tip of her wing, kissing all along the most sensitive feathers. Moving from there down the wing, and then slowly working back towards her sister's face. , and slowly began to stroke the feathers.

She let her mind rest against the wonderful, thick flesh pressing against her own. All the centuries of doubt melting away. Her sister's juices flowing, intermixing with her own.

Moaning, Lulu slid her tongue over Tia's horn. She took long strokes, making the unicorn moan and shudder in pleasure.

Gently, Tia spun Lulu around, so that each of their snouts were firmly pressed into the other's crotch.

Lulu began to work, lapping along Tia’s wide lips down to the tip of her slit, licking and suckling at clit ear for long seconds. Feeling Tia's tongue slide inside of her as well. She felt it pull at the inner flesh. She felt whole.

Celestia’s tongue teased Luna deeply, probing at Luna’s pussy as it slipped in and out, licking around every now and then, teasing at the lips only to return to her clit to suckle.

All the while the two moaned into each other, moaning and kissing well past the edge of formal discourse. Lulu, eyes still rolled up in ecstasy, didn't seem to notice the breach in etiquette. She could feel a pressure inside, now. It was a wonderful feeling.

Eyes closed, the moans still coming and slowly, her nethers dripping and her head shaking, her back was throbbing, but her mind was focused on the she could feel every inch of her sister's teats, and that amazing tongue sticking up inside her. Her tail swished at the touch, and she could give herself entirely to pleasure.

Lulu pushed her nuzzle in and kissed her sweetly, sharing the feeling with Tia. Her tongue went in as deep as it could. Her tongue's tip poking into the pussy with a lewd slurp. It was like her body had taken on a life of its own.

Sliding into the rhythm. They started in earnest, animalistically sating each other's needs.

The feeling of pure pleasure was more than she’d expected. Tia gripped and pushed, feeling her up with her magic for a second at a time. Lulu felt it pulse against her. The magic gave her head only a few moments to take a breath. She didn't always manage it, feeling Tia's tongue was wrapped firmly around her lips. The little moans continued to grow and spread as deep as they could.

The pleasure pushed itself to a boiling point, and the two mares shuttered in ecstasy, holding on tightly to one another.

It felt even better knowing it was a pony she cared for more than anyone else in the world.

Tia changed pace, giving her slow and affectionate touches. Kisses all along her body. Tia gave her side another slow kiss, eliciting another small moan from the blissed out pegasus on top of her.

They finally stopped, licking along her lips as much as she could get. The taste was everything she hoped it would be.

Finally, a hoof pressed against her wing and her mind finally came to rest.

Luna finished with a happy sigh.

It was a wonder no one could take from her.

Her sister kept her warm.

Lulu spun herself around, wanting to see that smile once more.

Grinning, Tia looked over her sister's shoulder, staring up at the eclipsed sun. "You know, I'd like to stay in here for a little while."
