While a certain meeting was starting in the safety of the Sugar Cube Corner in Ponyville, a young lavender Unicorn was running for her life.

Wait, what?

Okay, let's back up for a bit shall we?

Twilight arrived through her new, security locked teleport crystal to an eerie silence in Castle Canterlot. The letter she had received from Princess Celestia was short, and written hastily in, hopefully, dark red ink. She thought back to the odd letter...

"Dearest Twilight.
Come alone to Canterlot right away. The fate of Canterlot, nay, all of Equestria lays in your hooves.
Tia"

Wandering through the halls of the great castle, Twilight became concerned.

Not a servant or guard was to be seen anywhere.

Even during Celestia's heat there had been female servants and a few female guards present, but right now the place was deserted.

Her hoof steps echoed through the halls, each tap causing Twilight's pinned back ears to twitch.

(What's going on here? The Palace feels... dead.) She rounded a corner and saw a sight that caused her to gasp.

A solitary Royal Guard lay on the floor, not moving and barely breathing.

Twilight was at his side in an instant. “Hey, what happened to you? What's going on here?” She shook the guard.

His eyes fluttered open, a pained expression on his face. “N... Nightmare... Moon...” He then passed out again.

Twilight's eyes became pinpricks. Had she just heard him right?

Nightmare Moon?

Was she back? How? Princess Luna had been turned back to good by the Elements of Harmony, hadn't she?

Twilight had been in the Princess's presence enough to know that she had no spite or evil in her whatsoever, so why did the guard just mention that dark name?

Twilight dragged the guard into a small side storage room for the kitchen, then closed the door behind her as she left. He had not been injured, but looked more drained of his energy. The poor Pegasus.

She headed right for the throne room, expecting the worst.

When she arrived, the great doors were wide open. Twilight peaked in and saw it was empty.

“Hello?” She whispered. “Is anypony there? Princess?”

Silence greeted her ears.

Twilight swallowed her nervousness down and stepped through the great archway and into the throne room.

Not a single guard was to be seen. Even when Princess Celestia was not present there was always at least two guards on duty here.

(This is freaking me out...) She thought moments before her mane prickled and stood on end. Something was here.

She spun around, expecting something, ANYTHING.

Nothing.

“Twilight...” A soft, frightening voice whispered in her ear.

The mare spun around and came face to face with...

“N... N... Nightmare... Moon?” Twilight stepped back from the black mare that towered over her.

“Why hello Twilight. It is so good to see you again.”

“No... This is impossible. We defeated you with the Elements of Harmony.” Twilight stepped back, fear written clearly on her face.

Nightmare Moon's mane snaked out and caressed under Twilight's chin. “Defeated, but not destroyed.” Her smile was one that made Twilight feel even more fear. “I am the deepest desires of Princess Luna after all.”

“Wait a moment... You... You're not here to bring eternal night?”

“Goodness no, not this time, but I am after something I want. Something I have wanted for a thousand years.” She leaned down, her face inches from Twilight's. “And you will give it to me.”

“No... I'll never give you the Element of Magic.”

“Oh my dear foalish Twilight Sparkle. I care not for the Elements. What I want is something only YOU can give me.” Her mane wrapped around Twilight's hooves waist and neck, then lifted her off the floor. “You will give me your child.”

Twilight's mind clicked. “Wait, what?” A fear of a different sort crept into her mind. “No... You can't have my foal. I...” She looked down at her belly. “NEVER!!!” Her horn flashed and she vanished from Nightmare Moon's grasp.

Twilight appeared in her private chambers and activated all her security wards, locking the door and all the windows and blocking any form of teleportation into the room, but not out.

She rushed up to her library and grabbed all her spell books.

“There's got to be a way to turn her back. I can't let her take my foal.” She fretted as she poured through the books.

None of the spells she had learned so far were powerful enough to defeat Nightmare Moon. She was a freaking dark goddess for Celestia's sake.

“Wait, maybe I can get a letter to the others and tell them how to use my crystal. I can get them here and we can get the Elements from the tower... No, only Tia can open that vault. Pony apples...” She wanted to cry. She wanted to hide and cry.

But she was trapped INSIDE the castle with a monster. Alone, save for that single guard who would be of absolutely no use.

“There's no way to get through the barrier that surrounds the castle... If I can somehow weaken her enough maybe I can defeat her...” She pulled another book off the shelf and poured through it quickly.

“No good... I don't know any spells she can't overpower with her power alone. I might know more spells than her, but they're nowhere strong enough. I can keep running till help arrives... maybe.”

“Oh Twilight.” A voice echoed from outside her door. “I know you're in there. Open up and we can discuss what I want from you.”

“NO! NEVER!” Twilight cast another layer of spells on the door. It would take even Nightmare Moon some time to break through those wards on the door.

Yea, the door, but the wall?

The wall suddenly cracked, then crumbled.

Twilight made a quick mental note to magically reinforce the walls to her home, assuming she got out of this without her belly being ripped open by Nightmare Moon's sharp teeth.

She ducked low behind the desk, hoping the monster would overlook her.

“I can smell you Twilight. I know you are here.” A movement on the library loft, and Nightmare Moon looked under the desk.

Twilight had already teleported out and activated a couple prearranged spells. One being a tracking damper, and the other a teleport block. She heard Nightmare Moon scream in rage as she galloped down the hall as fast as she could.

(Gotta think. Gotta think. Nightmare Moon is Luna's desires... and she wants my foal. I can't let her have my baby.) She ducked into the hall leading to the servant's quarters and slipped into one of the many rooms.

From the looks of things, the servant who lived here had evacuated without even touching their food.

Twilight frowned on stealing, but she would be needing her strength. She wolfed down the sandwich and apples and slammed back the cold tea. She felt a little better, her mind starting to formulate a plan.

(If I can get her into the old vault, I might be able to lock her in till help can arrive.) She grinned for a moment, then shivered, goose bumps covering her body. She spun and faced the door.

Tendrils of dark blue and starry hair were peaking under the door. “I found you Twilight Sparkle. You cannot run. You cannot hide.”

“I can run.” Twilight teleported again. This time she was back in the main hallway outside the quarters, and galloped as fast as she could.

As she ran, she cast a silence spell on her hooves, and her running became a whisper. She ran through the halls...

And this brings us back to where we started.
...

Twilight rounded a corner and hid in a large vase. She levitated the lid on her and cast a couple more spells. One would mask her magical aura, and the other her physical scent. (This should keep her from finding me...) She hoped to Celestia that it would.

“I know you're around here. I will find you and take what I want, by force if need be. Your foal will be MINE.”

Twilight did her best not to move and held her breath.

The lid of her hiding place flew off and Nightmare Moon looked down at her. “Gotcha.”

Flash. Twilight teleported again.

“If you stop running, I promise... less pain.”

“I'd rather no pain thank you.” Twilight yelled back as she ran away again. A glance back, and Nightmare Moon was charging after her, and catching up. The black mare's legs were longer, and stronger than the Unicorn's.

Just as Nightmare Moon was on top of her, her mane starting to reach out to snare Twilight, she vanished again.

“You're such a fun plaything, but sooner or later, I will catch you. You will eventually have to sleep. I, however, do not.”

Twilight gritted her teeth and ran into a side office. The only way out was the small window. She threw it open with her magic and jumped up onto the railing. She glanced back as her horn started glowing brightly.

Nightmare Moon stepped into the office, a gleeful look on her face. “Yes, run all you... wait, what are you doing?” Her expression changed to shock as Twilight jumped.

Nightmare Moon rushed to the window and looked out to see a small lavender Unicorn sprout matching feathered wings and take flight.

“Oh clever filly you are.” She grinned and transformed into a dark blue cloud and flew after Twilight.

Twilight was glad for those flying lessons. She found she was fairly nimble and quick. No match for Rainbow Dash or Pinkie Pie, but she had learned fast.

Flying felt pretty good too, but this was no time to be enjoying being airborne. She was running, er, flying not for her life, but for her unborn foal's.

“You may be faster than a cloud, but can you out fly a Princess?” Nightmare Moon transformed and flew on wings of pitch black. Her speed was awesome and she closed the distance quickly.

Twilight had only one advantage in the air. She was smaller and more nimble than Nightmare Moon. She evaded the first flyby barely, and kept weaving out of the larger mare's reach whenever she came close.

Twilight finally saw a chance to escape. A narrow window. She dove and flew for it, casting a toughening spell on herself. She snapped her wings to her sides at the last moment and flew through the glass and crashed into the floor and wall of the room.

Outside the window came a loud crash and a scream, then silence.

Twilight struggled to her hooves. She was glad she had magically reinforced herself, or that would have hurt.

Not wanting to risk getting caught, she exited the room, shutting the door behind her as she ran. She had to find a safe place. Maybe she would now have a chance to get to the old vault and set up her traps. A couple hours was all she would need.

Rapid teleporting would speed up her travel, but also deplete her of the magic she was going to be needing. She chose to just hoof it. To recover some of her magic, she dispelled her wings.
...

The vault, it was old and had once held great treasures, but no longer. It was now empty and the great doors were opened wide.

Twilight stepped inside and looked around. It was clean in here, not a spec of dust. She could feel magic wash over her as she entered.

“Maybe I can use some of the existing enchantments.” She grinned.

“You would think so, wouldn't you Twilight Sparkle.” Nightmare Moon's voice came from the vault door.

Twilight turned back in time to see the great door slam shut with a thunderous boom. Instantly she tried to teleport, but her magic failed.

“Oh Twilight. There's no escaping me. I will have your foal. There is no escape.” She grinned, her horn flashing.

Magical blue bands appeared around the base of Twilight's horn, blocking her magic. Around her fetlocks appeared more blue bands, connected by chains. These kept her from being able to run. Finally, a band appeared around the base of her tail, forcing it into a lifted position.

“No...” Twilight backed away, nearly tripping over the chains. “Please... don't do this. Please don't hurt my foal.”

Nightmare Moon chuckled. “Whatever made you think I want the one in you?” She grinned. “I want you to make one in me.”

Twilight's eyes went wide. “WHAT?”

“I studied the gender changing spell that you perfected.” Her grin became wider. “You will give me a child, and you have no say in this matter.”

“But... L... Luna...”

“I am Nightmare Moon.” She screamed. “I am no weak little Princess Woona. I am the true Goddess of the Night. Now...” Her horn flared, the magic striking Twilight and transforming her from a mare into one with both genders. “I wouldn't harm your own foal. I have no interest in it.” She turned around and lifted her long flowing tail. “Now, come mount me. Make me a mother.”

Twilight could smell Nightmare Moon's strong scent.

It suddenly donned on Twilight. This WAS Luna. Her strong desires to have a foal, and after a thousand freaking years being trapped on the moon with no means to relieve herself when she went into heat...

A thousand years of heat, all rolled into one desire.

To become a mother.

Twilight felt tears run down her face, and she spoke softly. “Nightmare Moon?”

The black mare looked back, a little confused at the softly smiling and teary eyed pony. “You're too tall for me. Why don't you come lay down and we can... You know.”

Nightmare Moon turned around completely, an actual look of confusion on her face. “Why do you not fear me anymore? Ah, I know. You've realized your fate and have accepted it.”

“No, it's not that. Well, not entirely.” She smiled a little brighter. “You are my Princess, no matter your form. I can feel your desire. I am honored you have chosen me.”

Nightmare Moon simply smiled. “Indeed. You should be honored. You are a very beautiful mare, and a very hansom stallion. Our foal shall be even more so.” She walked up, towering over Twilight. She then lay on her side, presenting herself. “Now, mate with me.”

Twilight nodded and mounted Nightmare Moon. Inside, she knew this was really Luna. Scary as hell Nightmare Moon form Luna, but still Luna.

Twilight's cock slid between the tight lips of Nightmare's vagina, causing the large mare to gasp.

Nightmare Moon's head swung back as Twilight gently fucked her. Her breathing became filled with moans and gasps.

The Unicorn kept up her gentle thrusts, knowing even if she pounded as hard as she could she couldn't hurt her. But this was Princess Luna, and she would show her nothing but love as they mated.

The wet sounds increased along with a most beautiful sound from Nightmare Moon's throat as she came. Her vagina tightened and magic raced through her entire body like lightening. Her breathing started matching the pace that Twilight had set with her thrusts, each one nearly taking the Princess's breath away.

For over an hour, Twilight kept up the pace, bringing Nightmare Moon to a loving pinnacle of pleasure again and again. As wet as Nightmare Moon was, she was still tight, the wet slapping sounds echoing through the vault, mixing with the sounds of the pair's lovemaking.

Finally Twilight was beginning to tire. She started thrusting faster, and in turn making Nightmare Moon literally scream in delight. Faster she rutted the black mare, driving into her as deep as she could till she felt it. Her own, unprotected orgasm.

Nightmare Moon gasped at the sensation of being filled with almost liquid fire. She collapsed, completely drained, gasping for breath as Twilight shot the last of her seed into her womb.

Finally Twilight pulled out and collapsed. She had passed out before she had even hit the floor.
