Princess Celestia sat quietly in her throne room, leaning against a pillow in front of her fireplace as she read over a letter from her number-one student. It was late, the moon was low, and stars shined brightly through the drapes that fluttered in the light, evening breeze. Celestia closed her eyes and took a deep breath through her nose, the sweet mountain air filling her lungs.

"Ahhh. What a lovely evening." She said as she rolled the letter back up.

Suddenly her peaceful night was interrupted by an angry blue pegasus wearing a striped toga. Rainbow Dash had burst through the open window, taking down a curtain as she did so. Clasped in one front hoof was a container of Nutella, in the other a spoon.

"IT'S GO TIME!!!" The pegasus screamed at the top of her lungs.

Celestia narrowed her eyes and threw her letters off to the side as she rared up on her back hooves. "It would appear so, Rainbow Dash!"

The quick little pegasus darted forward, kicking off the windowsill and leaving a thick rainbow in her trail. Celestia braced herself for impact, and caught Rainbow Dash against her chest, sliding backwards.

"At least this time... you brought dessert!" Celestia said as she struggled to keep the upper-hoof on Rainbow.

Dash planted her back hooves firmly on the floor and used every ounce of her strength to fight against the much bigger mare. Celestia grinned as she felt the young pegasus' forelegs beginning to quiver.

"Tired already, Dash?" She scoffed and shoved her to the floor.

Rainbow leaped back to her hooves and crouched away. "Don't think I'm giving up that easily!"

"Ooh, you think you can actually take me this time? Or are you  just gonna fold and roll over like you always do?" Celestia mocked.

"How about you go buck yourself!" Rainbow shouted, anger burning in her eyes.

"Oh, you'd like to see that, wouldn't you? Hmm?"

"Very funny, Tia." Rainbow glared with a smirk.

Celestia's eyes lit on fire, and she punched her front hooves together. "Now you're asking for it."

Rainbow darted at her once again, leaving the treat and spoon on the floor behind her. Celestia grabbed her front hooves and swung her around, throwing her into the wall. Rainbow was quick to regain her balance before crashing, then kicked off the wall. Before Celestia could grab her again, the speedy little mare crashed into her chest full force, her back hooves kicking her directly in the rib-cage.

Celestia tumbled over and slid across the marble floor, clocking her head against a stone-pillar. She held onto her side, groaning as her crown rolled away.

"Ha, didn't expect that one did ya?!" Rainbow boasted.

Celestia leaned up, her vision blurry. As her sight came into focus, two blue hooves knocked her out cold.

"Ow... my head..." Celestia leaned up and looked around.

"Good morning sunshine." Rainbow fluttered just out of reach over the bed.

Celestia lit her horn to grab the mare, but nothing happened. She reached up to feel a steel ring clasping her horn, and growing hotter as she attempted to release magic.

"Hey. I'd be careful if I were you. I wouldn't want anypony getting their horn burned." Rainbow landed on the bed and began crawling up Celestia's body.

The princess forcefully threw her head back and squeezed her eyes shut. "Ugh, how did I let this happen."

"You got careless. I told you that one day you'd have to wear the toga." Rainbow threw on a cocky grin and dangled the article of clothing from her teeth.

"... Right."

"Put it on, or we're gonna have some serious trouble." Rainbow dropped it on her chest and licked her lips.

With a disgruntled sigh, Celestia wiggled her way into the much-too-small outfit and bemusedly glanced back at the pegasus. "Happy?"

"Very." Rainbow giggled and jumped onto the bed, laying on her back. "Now it's your turn to buck me, finally..."

"Yeah yeah. Let's get this over with. And you better enjoy this, because you'll never beat me again." The princess gritted her teeth and swallowed her pride. "So Miss Rainbow Dash, what will you have your pretty pony slave do first?"

Rainbow chuckled and rubbed her hooves together. "I'm already loving this. Alright, pretty pony slave, first thing's first. Rub the Nutella on my hooves."

"As you wish, ma'am." Celestia took the jar in her hooves and listlessly began slapping in onto the two blue hooves in front of her.

"And now you have my permission to lick it up." Rainbow quivered in anticipation as she watched Celestia's face twist into a grimace.

"... Dash, you know I HATE Nutella."

"THAT'S MISS RAINBOW DASH TO YOU!" The young mare shouted, then lifted her back hooves closer to the princess's face.

Celestia groaned once again, then did as she was instructed. "Yessss Miss Rainbow Dash..."

"That's a good girl. Lick it all up. You know you like it, don't ya you little whore." Rainbow closed her eyes and leaned back as she had her hooves thoroughly licked.

Celestia closed her eyes, cringing as the paste made contact with her tongue. "This stuff is absolutely disgusting. I don't know how you and Luna can handle it." She said as she continued licking the paste off Rainbow's hooves.

"It's not that bad. Not bad at all..." Rainbow gasped and covered her mouth as Celestia's tongue tickled the center of her hoof.

"Okay, ma'am, I'm done." Celestia wiped her mouth and eyed the two sparkling clean hooves in front of her.

"Uh, no... no you're not. I still have two more hooves, and that's a full jar of Nutella. You have a lot of work to do." Rainbow held her front hooves out and closed her eyes.

The princess sighed and slapped another helping onto the hooves.

"This is nice. See? I'm so much nicer than you. Now go ahead and slap some of that sweet stuff on my sweet spot." Rainbow said as she looked down into Celestia's eyes as they peered over her hooves, her tongue swashing around them.

"Yes Miss Rainbow Dash." She nipped at the tip of her hoof as she reached for the jar yet again.

Rainbow swatted the princess's flank as she knelt over the edge of the royal bed. "That's a sweet ass you've got there."

"Thank you, would you like a taste?" Celestia asked, glancing back over her shoulder with seductive eyes.

"Nah, not tonight. I'm all about relaxation this time. You're gonna take care of me for a change. It's not everyday I get to have a sexy princess as a pretty pony slave." Rainbow laughed, then closed her eyes as Celestia began to apply the paste to her sweet spot.

"Yes, ma'am, with pleasure." Celestia rolled her eyes and bit down on the mare's crotch, her tongue slurping up all traces of the Nutella as quickly as possible, but not stopping when she was done. She bit down and licked as hard as she could, hoping to make this go by as quickly as possible.

Rainbow was surprisingly calm. "Yeah, that's it. Eat me you dirty little freak."

Celestia simply nodded and kept at it. Rainbow looked down at the long beautiful mane glowing and waving across the bed. "That's really nice, Celestia. Mmm. Do you have any idea how long I've been waiting for this? It's crazy, I wonder how many ponies would kill to... Oh yessss," She bit her lip, "... uh, kill do be in my position right now."

Celestia shrugged and shoved her tongue inside, causing Rainbow's voice to crack as she squeaked.

"I wonder what Twilight would think."

Celestia's head shot up. She wiped her mouth and choked. "Ah, no! No! You can't tell her!"

Rainbow immediately spotted a moment of opportunity. "Or what?" She asked.

"Or I'll... I'll banish you to the Everfree Forest... I'll throw you in a dungeon! I don't know what I'll do, but I assure you that you don't want to find out." Celestia narrowed her gaze and her voice took on a sharp edge.

"Ha! I don't think you'll do anything. Why don't you want me to tell her? Embarrassed?" Rainbow asked with a laugh.

"Look, I like this. This little game we play. I've never done anything this strange or exciting in all my years on this world. But Rainbow Dash, I can't allow you to tell Twilight about this. It'll mess with her morals, and I need her. She's meant to fill a very important role in the future. Please, listen to me." Celestia pleaded, bowing her head.

"Hmmm. Okay, I won't tell her. But it seems like you're going to have to wear the toga more often from now on." Rainbow winked.

Celestia sighed, then chuckled. "You got me..."

"Now then, my pretty little pony slave. You've got half a jar of Nutella to finish eating. Get to it!"
