Celestia, Dash, Soarin and Spitfire.

~300 Years Ago~

"Princess, coming to bed?" Rainbow Flash asked his mare-friend seductively.

"Flash, I am tired. Can we not do this tomorrow?" Celestia's voice rang through his ears.

"But, Twilight Glimmer said the spell was only semi-permanent!" Flash whined, flapping his wings and dragging Celestia to bed with his magic.

"I must admit, you do look dashing as an Alicorn Flash." Celestia grinned.

"Celly, maybe we could... We could do something new."

"I want this but I don't at the same time!" Celestia said, her tears pouring from her eyes.

"But we could have children!" Flash cried.

"Flash, I..." Celestia began to break down, tears and emotions breaking her body.

"Okay Flash, let's do this."

~Present Day~

"Your Highness, Prince Blueblood is here to start your meeting... Princess Celestia?... PRINCESS!" The voice of Royal Advisor Lightning Crash echoed through Celestia's daydream and brought her back to reality.

"Oh, yes. Send him in." She stammered, thoughts billowing around her vast mind.

"CELLY! WHATEVER IS WRONG AUNTIE?!" Blueblood's whines bellowed into the chamber, his ego preceding the majestic white coat and Blonde mane.

"I'm tired Nephew. Shall we begin?" She replied wearily, her mane hanging limp and boring.

"But… your mane!"

"Ignore it! Let us continue." Celestia called for some coffee, it would be a long meeting.

~4 Hours Later~

"Hngh. Why?" Celestia groaned, impatience penetrating her words.

"Why what Sister? We are… I am keen to know." Luna smiled, watching her civilian's dreams and nightmares.

"Why did Blueblood's meeting take FOUR HOURS?! It is already nighttime!" She whinnied, stomping her hooves in anger.

"Do you have better things to do? I thought you just sent letters to Princess Twilight." Luna grinned, her smile echoing the dreams of three ponies and her amusement.

"Whomever are you watching Luna?"

"Soarin, Scootaloo and Rainbow Dash."

"Tell me more."

"Well, Soarin is dreaming of being chased by Dash and Fire, whilst hoping Dash shall catch him. Scootaloo is having vivid dreams of flying with Soar and Dash, and Dash is dreaming of Soarin and... You." Luna finished with a smirk.

"Me? Why me?" Celestia frowned.

"Only wondering why you are so against her being a Wonderbolt." Luna smirked.

"Well you know why!" Celestia blurted.

"What, because Rainbow Dash is your great-great-great-great-great grandfoal?" Luna laughed.

"YES!" Celestia bellowed, angry at her sister's laughter.

"You made a mistake. I'm never going to let you forget that you made a mistake as did I." Luna sobered up, laughter leaving her dark form.

"Luna, I had to punish you for your actions. This was different!" Celestia's panicked eyes flickered from the door to Luna.

"Oh really? I come back from Imprisonment to find Discord roaming free, Twilight your new student and you have a family!" Luna growled, her anger and hatred for her moon obvious through the anger for Celestia.

"Luna! Please forgive me! Discord had reformed and Rainbow Flash had been Alicorn."

"I still think a Punishment is in order." Luna smiled, but her smile was different.

"What should my punishment be Young Sister?"

"Sexual Favours. From Discord." Luna laughed, knowing this was tough on Celestia.

"No way! No! I would never... Discord… sister please!" Celestia stammered, her eyes darting for any means of escape.

"Go find him, Bring him HERE, then Buck him." Luna snarled, anger shooting from her horn. Celestia took off, her eyes wide in horror.

~1 Hour Later~

"Discord! Thank Twilight I've found you! Come with me quickly!"

"Wait… WHY?!"

~30 Minutes Later~

"Sister, you returned with Discord as I asked!" Luna clapped her hooves together.

"I do not understand why though?" Discord asked curiously.

"Oh, no reason!" Luna giggled as she used her magic to stuff Celestia into a Black Latex suit with gaps for her mare-hood, ass and mouth. She couldn't see nor hear the two ponies next to her and her magic was stopped by the Latex coverings.

"Buck her Discord." Luna states simply.

"No! You expect me to… when I'm… FLUTTERSHY!" Discord wailed in protest.

"Whatever was I thinking? That dream had more to it didn't it?" Luna grinned, once again summoning her magic. Thick metal chains clasped Celestia's front hooves together and hoisted her up into the air. Two more metal clamps chained her back legs apart so her glistening mare-hood was visible. A ball gag kept her mouth wide open.

"I… Fluttershy…" Discord wept, his stallion-hood erect and twitching.

"Go on Dizzy. Don't fight it." Luna egged him on, waiting for this spectacular performance.

Discord walked forwards and saw the wet and glistening mare-hood of the Sun Princess. He raised a claw to it and plunged it in, teasing her clit at the same time. Through the ball-gag Celestia's moans of pleasure were audible.

"Just like that, yeah!" Luna cried, plunging her hoof deep into her own tight pussy.

Discord was ready to mount Celestia when her thought he heard a voice from behind him. He turned to see Luna indulging in some activities of her own. Smiling to himself he used his magic to Bound and Gag Luna exactly like Celestia. He plunged his cock deep into Celestia as he plunged his claw into Luna. Both mares squealed with glee through the gags.

~10 Minutes Later~

"Luna… that… was… my… punishment?" Celestia gasped, air being an item she was short of.

"Indeed… sister…" Luna panted, smiling at Discord's new dreams as he lay passed out on the bed.
