"WHAT DID IT SAAAAY?!" Luna shouted again, louder then ever.

Rainbow Dash studied the letter again she was in absolute shock at what it said and wasn't sure how to react. She read it in her head again wondering if she was going completely mad or if the princess of the sun had.

My dear little pony Rainbow Dash. First of all I would like to ask you not to share the contents of this letter with anypony else. I would like to inform you that I am completely aware that ponies believe that Fluttershy and Rarity are missing. I know the whereabouts of both of them. Fluttershy is performing a friendship experiment that I have approved and am allowing her to play out, with as little influence from myself as possible. Fluttershy wanted to have a long drawn out fetish granted and since it is Rarity's job now, she came to me for help to try to grant her friend's wish. Your friend Fluttershy is deliberately letting herself be ponynapped and tortured and wants her only escape to be her friends rescuing her. I know you must have a lot of questions, so please come to the top of the west tower of Canterlot castle in one hour.

- Princess Celestia

"WELL?" Luna snapped in frustration at the suspense.

"Uhhh". The cyan pegasus started hesitantly. "Princess Celestia needs to see me in secret very soon, I'm sorry but I'm not allowed to tell you anything".

"What?!" the dark Alicorn questioned. "Why not?"

"I... I don't know, Celestia's orders" Rainbow Dash shrugged.

Luna looked puzzled and annoyed. "Why does Celestia insist on keeping things from her own sister? We are supposed to rule equally, well at least as much as I can rule when I'm in charge of the night" Some resentment was noticeable in her expression.

"Please Luna...." Rainbow Dash was a little scared; if Luna really wanted she could simply take the letter from from her with her magic. "I don't know Luna, I'll be sure to ask Celestia just that".

Luna stomped her hoof and this time her loud voice was entirely intentional. "TELL HER THAT WE ARE TIRED OF BEING THE INFERIOR SISTER, WE WANT TO BE TRUSTED LIKE A SISTER SHOULD!"

Rainbow Dash gulped. "Yes your majesty, I will tell her that". Rainbow Dash held the letter tightly in her teeth and then took off into the air, hovering for a moment to stare at the displeased princess. She sped out the east window and then circled around to the west at a low altitude, so that if Luna tried to follow her she would think she went in the opposite direction.

Rainbow Dash arrived at the west tower early and relaxed appreciating the great view of Canterlot from the tower, the whole ordeal gave her one of the best workouts she ever had, but now her wings were sore and needed to recover. But she knew that even in this state she would be faster then most freshly rested pegasi. It was a restless few dozen minutes that Rainbow Dash had to wait before Celestia and her shimmering mane came into view. Even when Rainbow Dash was tired she had trouble sitting still. She wished she had a book to read, but didn't have time to get one when she left Ponyville.

Rainbow Dash didn't even let the princess land in the tower before she started throwing questions. "What is going on princess, Why does Fluttershy want to be ponynapped, who ponynapped her, why is Rarity involved?" She started spouting out without taking a breath. Celestia looked at her with a look of authority that demanded respect and stayed silent and she sat down and got herself comfortable. The rainbow maned mare realised her fatal mistake and bowed her head down in apology.

"Oh I'm sorry princess, I...I...I have no right to talk to you like that.” She stammered.

Celestia waved her hoof and chucked a bit at her subservient subject, she always found it humorous how much her subjects feared making her angry. It was funny, but at the same time she wished the ponies didn't see her as such a tyrant. "I suppose I do have a bit to explain, however, I must ask you to stay in Canterlot until I say you can leave.”

"But my friends, they are really worried, they need to know Fluttershy is.... okay.... I guess" She replied hesitantly. Then dozens more questions littered the pegasi's mind as she started to think about a innocent little filly like Fluttershy wanting to be ponynapped."

The Princess nodded her understanding. "I know this must be hard to understand, so let me explain it from the beginning, at least from when I was first made aware of it. It was two weeks ago when Rarity visited me for a petition, but she tried to disguise herself, if it had been any other pony I would have surely turned down what she requested. But I have a special love for the ponies that have saved my kingdom three times and I felt I owed each of you some favours."

Three weeks earlier...

Rarity felt hot and bothered in her tight black latex, but she had to do whatever she could to make sure no pony in Canterlot and especially Celestia would recognise her. She got a lot of strange looks as she walked through the streets and she rushed as quickly as she could to the entrance to the Canterlot castle. But as she feared she was stopped by the guards.

"Who goes there?" Asked the guard.

"I request to make a petition to her majesty" She replied in her deep gravelly masculine voiced masked by the metal collar.

"Who are you?" The guard asked.

"That is none of anypony's concern", replied Rarity.

"I'm not about to allow a strange masked pony to see the princess, lift your mask or begone!" The guard ordered authoritatively.

"Urgh, I can't reveal who I am, but I mean the princess no harm, I just want her help" Rarity started begging.

The guard shook his head. "No, not unless you remove your mask".

"Please". Rarity asked going down on her knees with her front hooves together.

"No!" The guard repeated annoyed.

"Please please please please please please please" Rarity persisted. But unfortunately with the collar her voice did not sound as whiny as it did with the Diamond Dogs and was a lot less powerful. It just lead to the guard summoning more of them with a call and had her forcefully removed from the bridge and then tossed back into the town.

Rarity sat there and pouted, but nopony could see it behind her mask. She started to walk slowly away from the castle and back into the town while she started to try to think of a plan to see princess Celestia without revealing her secret. She cursed her lack of proficiency with magic. All she could do was telekinesis and gem detection that she knew of and she could not think of anyway those could help her get into the castle.

All of a sudden she felt herself falling into what seemed like a void of nothingness. Her heart pounded and all of a sudden she felt carpet beneath her hooves but didn't it feel like she landed on it, it was a strange sensation, she had never been teleported before and she stood there for nearly a minute in a confused daze before she looked up and saw Celestia in front of her.

In a rushed panic she bowed before her princess and began to gasp loudly from her nervousness of suddenly being in front of her. She normally had time to psyche herself up before meeting the princess.

"What brings the element of generosity here?" Celestia asked bluntly.

Rarity looked around at the room and saw six guards standing there watching her.

"I'm not the element of generosity" Rarity objected. She had no idea how Celestia knew who she was and she had no idea why she thought she could fool the powerful alicorn. She cursed at herself in her head for even trying. Celestia could see her distress and knew that Rarity was likely hiding for a good reason.

"Guards, leave us two alone, I know this pony means no harm, but I would like us to have privacy". She ordered.

The guards nodded in obedience and left the throne room and took guard outside the door instead.

"You can't hide from me Rarity, now I would like to know why you are here and more importantly why are you trying to hide?" Celestia said in a kind but demanding tone.

Rarity removed her mask and collar, and revealed an unusually disheavled purple mane, relieved to be free of their heat and restriction. She bowed before the princess and tried to explain her situation as best she could.

"It's Fluttershy your majesty, I want to help her make her ultimate fantasy come true, but I have realised that it's impossible and I need your help".

Celestia invited Rarity into the same five star suite she had been given during her past visits to Canterlot. Rarity explained everything about Redblood and Fluttershy and with a lot of shame, the situation she had got herself into with Filthy Rich. Rarity was very nervous about Celestia's views on such seedy activities, but was surprised when the princess simply started sharing some of her own kinky fantasies. After the most stimulating and honest chat Rarity ever had with another pony, she felt a lot more comfortable about the sex shop job she had taken on and that it wasn't something to be too ashamed about. But that didn't mean that the socialites in Canterlot would be anywhere near as open minded and she was still worried about her best friends.

"So what do you want?" asked Celestia bluntly after an hour.

"I'm not sure" Rarity replied. "I just want your help to make this happen for Fluttershy.”

"Very well" Celestia grinned, she was actually getting excited about helping her most important subjects. "I'm going to give you something" The tall white pony touched her long horn with the smaller one that Rarity had. All of a sudden Rarity's horn started to spark and crackle with electricity.

"Ahhh!" Rarity felt pain as the power rushed not just into her horn, but also into the rest of her body. She suddenly felt aware that the magic filled every one of her muscles, even right down to her hooves. All of a sudden Rarity shot a deadly beam of energy upwards and smashed a hole in the skylight of the throne room.

"I'm so sorry, I can't control it!" Rarity panicked and tried to aim her horn down only to nearly cause more damage to the wall. But Celestia was intuitive and quickly surrounded Rarity with a shield that absorbed the magic that she couldn't control.

"It may take a while for you to learn to have control having this amount of power" Celestia said. "But I will help you".

The beam coming from Rarity's horn began to get thinner and then fade until her horn began to just crackle with electricity. She slumped to the ground in exhaustion, her horn hurting from the experience.

"I'm so sorry for smashing the skylight princess". She bowed submissively.

"It's okay" Celestia smiled. "It's going to take some time, to train you to be able to temporarily hold a alicorn's power, but since you are a unicorn, it will only be temporary and will fade quickly, you will have to come back to me to recharge".

"Okay Princess" Rarity bowed in thanks.

"However, you must know that every time I give you this power I am temporarily drained, so please only come back for more when you really need it, or I will be left drained of my own power to protect the kingdom".

Rarity nodded, ready to learn to contain this new power. She honestly couldn't wait to feel more powerful then Twilight Sparkle for once, but she reminded herself that it was strictly business.

“Also If I get any letters from any of your friends asking about the whereabouts of Fluttershy or anypony else, I will have no choice but to reply honestly” Celestia explained. “There is a book in Twilight’s library about the magic of sending, receiving and even blocking letters, I would suggest borrowing it, because the first thing Twilight is going to think of is sending me a letter”.

“Yes your Majesty, thank you for your help”. Rarity nodded.

_________________________________________________________________

Rainbow Dash had been enjoying the luxury comfort of the Canterlot palace for nearly a week and as great as it was she was getting bored. She decided to go out for a flight to stretch her wings and make sure she didn’t get rusty when Celestia would finally be able to return to Ponyville. When she asked the princess why she didn’t want her going back, she said it was because she now knew what was really going on and that she had disqualified herself being being one of the ones to rescue Fluttershy and Celestia didn’t want her knowledge to influence Fluttershy’s little experiment.

Rainbow Dash flew out of the window and began to practice her tricks and practiced getting close to but not pulling off a sonic rainboom, as it would cause too much fuss from her friends who would see it from Ponyville not to mention everypony in general. She just wanted to make sure she could still do it at will if she wanted.

As she started to fly over the gardens surrounding the castle they reminded her of Fluttershy and how mad she got about being unable to befriend the animals here, if there was one thing that Fluttershy hated it was to not be loved by any creature pony or animal.

As Rainbow Dash continued to explore the beautiful gardens from above at high speed she saw something that looked out of place. It was a pony sprawled out on the ground, it was wearing a black latex suit that completely masked their face and anything that they could be identified by, all the rainbow maned pegasus could tell was that it was a unicorn. She landed next to it to investigate.

“Hello?” The cyan pony asked inquisitively. “Are you awake?”

The latex pony stood up slowly and shakily, clearly in pain and was gasping for breath.

“R-Rainbow Dash?” the pony asked as it took in a deep breath of air, the voice sounding gravelly and masculine.

“Yes, it’s me the greatest flier in all of Equestria” She responded vainly. Rainbow Dash figured that she was already famous as both the Element of Loyalty and the only pony that can do sonic rainbooms so she didn’t think much of the pony knowing her name.

“Please… I need to see Princess Celestia, hurry” the pony said amongst groans of pain, she was so weak it hurt to speak.

“Why should I let a strange pony see the princess?” Rainbow Dash demanded to know.

“I… uh” The latex pony looked unsure about what she should say next and decided to just take her mask off revealing her unusually unkempt purple mane. “It’s me Rarity”. She submitted.

“Oh? Are you here about Fluttershy?” Rainbow Dash asked. She was starting to really miss Ponyville and all her friends.

“Yes please, I need Celestia to give me more power, so I can keep Fluttershy happy a bit longer.” She replied.

“Yes mam!” Rainbow Dash gave Rarity a salute and then speed off to the castle. She was worried about Rarity’s health and she knew that Celestia would be the best one to help her.

__________________________________________________________________

Celestia soon landed down next to the injured pony with a disapproving look. “Rarity, what are you doing here?”

“I’m sorry princess but they want more time” Rarity replied.

“I think this experiment has gone on long enough” Celestia said softly but with authority. “It’s time to end it.”

“Yes, I agree princess, but right now my sister and her friend found the house and I think Scootaloo escaped to tell everypony, so I imagine Twilight and everypony else is going to march down on us and kill Redblood” Rarity panicked. “So I need more power so I can move the house one more time and then get all the ponies in the same room so that they can understand that Redblood and I are not villains”.

“Rarity… Everytime I give you this power I leave myself vulnerable”. Celestia scolded. “But I see your point, put an end to this now, even if Fluttershy doesn’t get her dream of being rescued, her selfishness is starting to get out of hand.”

“Yes I know, It’s just I felt she deserved to have what she wants and I wanted her to have it”. Rarity nodded.

“There comes a point when you can be too generous Rarity, I want you to consider this a valuable lesson.” Celestia said to her and Rarity nodded submissively.

“Don’t let other ponies use your generosity to just tread all over you, you need to say no if they start to become a real burden on your own well being or other ponies that are affected.”

“Yes Celestia, you are right.” Rarity bowed. “I let my landlord basically sell me into slavery…I completely understand now.”

Celestia touches Rarity’s horn with her own and first begins to heal her while lending her the power of an alicorn one last time.

“Thank you, Celestia.” Rarity says genuinely as she feels the warm rush of the power course through her.

Present day…

Pinkie Pie had a angry look on her face as she followed the three fillies into the Everfree forest. She was ready to kill Redblood and as much as she wanted to keep the fillies safe by making them go back home, nothing she said could convince the determination of the Cutie Mark Crusaders. Her only option was to follow them and keep them protected that way.

The crusaders had a determined look of revenge on their faces, whoever had caused Sweetie Belle to break her horn was going to suffer their wrath.

“Cutiemark Crusader Avengers, charge!” Applebloom shouted as they ran into the forest.
