The plot

Luna had become bored of sitting at her sisters side every passing day and ever night, raising the moon as her sister lowers the sun and vice versa, she was getting restless in many ways. She had begun to plan, a plan to take the kingdom for her own selfish needs, she wouldn't call it selfish, she just wanted some power.

A grand gala was being held late in the night, all of Canterlot would be there. The Mane Six would not, Luna made sure of that, destroying their invites and forging a letter from Celestia before her plan would really start.

Luna trotted over to her sister who seemed to be looking for Twilight Sparkle or Rarity. Normally Luna would be conversing with Fluttershy, not tonight.

"What's wrong, sister?" Luna asked, gently nudging Celestia with her navy wing, Celestia sighed before hanging her head low.

"My student has not arrived yet, I should send another invite, I'm sure she can make it in time with her friends." Celestia said before poofing a scroll into existence with her golden magic, Luna lowered it with her dark blue magic, celestia gave a questioning look.

"Celestia, I promise they're fine, it's a gala, you should have some fun, or start the speech if you want to get it over with," Luna offered, Celestia nodded before walking up to the podium, Lunas horn glowed weakly as she forced the bear traps into invisibility, said traps made of modified materials, only modifiable by her magic, if someone is ensnared, they stay there until Luna says they're free.

Celestia cleared her throat before tapping the podium, everyone stopped conversing before turning to look at Celestia, Luna nodded for Celestia to begin.

"Ponies of Canterlot, we sadly do not have the Elements Of Harmony with us to celebrate this momentous occasion, tonight, for the first time in a millennium, my beloved sister Luna will bless us with a blood moon." Celestia boomed out over the crowd, all eyes were on Luna who smiled softly before letting her horn glow, the moon above slowly change color as she tried to snap the bear traps in place on Celestias hooves.

When the moon reached a lovely crimson, the crowd cheered and Luna ensnared Celestia in the bear traps. The diarch screamed at the sudden pain and the crowd froze as Luna trotted up to her struggling sister. Luna simply ensnared Celestia neck with a chain before linking the beartraps to a single chain, Celestia froze, not daring to move.

Normally the solar princess would be attacking without abandon, but with was Luna, her beloved sister, only sister. Not Nightmare Moon, was it Nightmare Moon in disguise? Celestia didn't know, nor could she think with the fact her sister was leading her across the castle grounds to the main lawn, placing the solar diarch in front of the fountain.

Luna placed a sign beside her sister before chaining Celestia to the ground, the sign read 'Public fleshlight' Celestia shuddered. Luna shot a blast of magic at Celestia, hitting her sister easily, heat shooting across snow white fur. The blast of magic forced the princess into heat, Celestia was panting and legs weak in mere minutes before Luna left.

Luna trotted across the castle grounds once again, finding few scattered ponies, hitting them with similar blasts of magic before they turned to predators, each one living only to fulfill their sexual dreams. She caught some of them undergoing vore, others fulfilling dreams oviposition and inflation, the magic that strong. She pushed open the door to her room, a large ledge parallel to the entry door, she trotted to the ledge, a window pushed open so she could sit out there.

She pulled up a few scrolls, duplicating 'Celestias' printing for each letter, she knew they would work, they had to.

'Twilight Sparkle, Luna has become corrupt and trapped me down below in the dungeon, I don't know where I'll be or what state I'll be in when you arrive, but I need you to come and save me, for all of Equestria, your mentor, Celestia.'

Luna poofed the scrolls away, each one varying slightly for each of the Elements, she knew they would work, her plan would go into full swing very, very soon.
