Daughters of Nightmare

All of Nightmare Moon's plans have failed so far. However, she has come up with one idea to stop Celestia's student and her friends once and for all. Nightmare Moon quietly watched as Twilight and her new friends entered the castle. Just when Celestia's student had collected the stoned remains of the elements of harmony, she made her move. Nightmare Moon teleported all six mares into the tallest tower and left the elements behind.

"What in tarnasion just happened?" asked Applejack.

"You have reached the end of your journey, my little ponies." replied Nightmare Moon.

At the sight of her, the group immediately got ready to attack. Nightmare Moon was, unfortunately, faster than they had expected. She enveloped the group in her magic and brought them closer to her face and gave them a devilish smile.

"Let us go! You won't get away with whatever you have in mind." said Twilight struggling against the dark alicorn's magic.

"I disagree. What I have in mind is that you’re going to help me rule this land, whether you like it or not. replied Nightmare Moon.

That statement shocked the six manes into silence.

"There's no way that we'll help you." stated Rainbow Dash once she got her voice back.

"You'll be changing your minds very soon." said Nightmare Moon as her magic got brighter.

Before any of them could ask, they all noticed that they all were getting younger as Nightmare Moon turned around and revealed her marehood. It was then that Twilight knew what Nightmare Moon was planning. Unfortunately, she was unable to tell the others due to them regressing back into foals. Nightmare Moon's smile only grew upon seeing this. One by one, Nightmare Moon levitated each of the foals into her womb leaving Twilight for last. Twilight continued to struggle as she was placed into Nightmare Moon’s birth canal and gently pulled into her womb. She tried to escape by the way she had entered, but the entrance had closed. The purple unicorn filly kept trying to reopen the cervix, but to no avail. She eventually stopped when she felt something pressing against her belly. When she looked down, Twilight saw that an umbilical cord had attached itself from Nightmare Moon's uterus to her belly button. Twilight also spotted five more umbilical cords each connecting to one of the others.

"This really can't be happening. I'm so sorry, Princes Celestia. I have failed you. thought Twilight to herself as she drifted off to sleep.

Nightmare Moon was overjoyed that she had finally bested Celestia's student and her team. She could still feel the young unicorn trying, but that didn't last long. The moment she felt body took to the six inside Nightmare Moon knew that could stop her. Suddenly, a bright flash of light briefly engulfed the room causing Nightmare Moon to cover her eyes. When she could see again, Nightmare Moon spotted Celestia standing where the light had been.

"WHAT YOU DONE?!" asked Celestia in a rage.

"Made sure that I have a way to make the night truly last forever. replied Nightmare Moon.

"Let them go, now, Luna. demanded Celestia through clenched teeth as tried to hold back her anger.

"That's Nightmare Moon to you. Plus, I can't. They're already in the process of becoming my children. said Nightmare Moon placing a hoof on swollen abdomen

Celestia was reduced into silent at that news. Her plans to teach Twilight about friendship and get her sister back, were now both up in smoke. As she tried to figure out what to do next, Celestia felt herself being lifted off the ground.

"What are you doing? Stop it, sister. said Celestia seeing that she was being drawn towards Nightmare Moon's open maw.

"My little ones are going to need their nurturement, if they are going to be helping me rule this land.

Celestia's eyes widened in realization and horror at Nightmare Moon's statement and asked "You plan to eat me?"

"Indeed." was all Night Moon said in response.

Before she could react, Celestia found her head being shoved down Nightmare Moon's throat. The whole ordeal took the sun princes by surprise. By the time she had regained her senses, Celestia was already completely stuffed into Nightmare Moon's stomach. Celestia tried to teleport her way out, but quickly discovered that a special barrier was lining the entirety of Nightmare Moon's gut. She tried once more to convince her sister to change her ways to no avail.

"Enjoy your brief time inside of there, Celestia. And don't worry about your student. She'll make an outstanding daughter alongside the others. As for Equestria, it's much better hooves now." said Nightmare Moon laying down.

Celestia could only whisper a soft sorry as closes her eyes.
