Don't be silly I am fine.

Celestia knew that her only way of successfully continuing her pursuit in lust, would be to fool the ponies into believing her lies. She had been crafting a story in her mind as she walked away from her sister's room and began her journey to the throne room. She wasn't going to allow anypony to interfere in her conquest of Luna.

She had been making gains and the book had been helpful in unlocking her hidden desires for the sweet younger mare. She wanted to make Luna's body sing in pleasure and have her submit. The right of mating with Luna belonged to Celestia only, at least her mind thought so.

Angel Bunny was still being chased by Discord, across the expanse of Ponyville. He was hoping to outrun the chaotic entity, with the goal of protecting his owner's dignity. As he ran, he began formulating a plan. He kept running even when nothing was chasing him.

Discord had gotten bored of chasing the rabbit around, and began spying on some mares bathing through open windows. His target was two lovely mares that seemingly have been in a long time relationship, seeing their intimacy, "Oh yeah, you rub that unicorn's horn you dirty earth pony... you candy making slut... rub her horn more."

In his fervor he forgot about the entire situation of Angel Bunny and the stash of Fluttershy pics. He even forgot he accidentally created a super tortoise, and in that instant he didn't give a buck if he did remember. He was stroking himself into a frenzy and wasn't even paying attention to the passing ponies walking away in disgust.

Celestia had reached the throne room and sat on her fancy throne before addressing the ponies, "It seems you all have important news to share, otherwise I am sure this meeting wouldn't be taking place. Please Twilight Sparkle let me know what is the nature of this emergency."

Twilight didn't see a sex crazed pony hell bent on seducing her sister, instead the facade of a noble princess was impressively working on the astute pony. "Well it's about a book that may have come into your possession recently. I was wondering if you have already began reading it?" she asked the ruler of Equestria.

Celestia looked at the faces of the ponies hoping for a no and there worries to be calmed, it was too easy for her to get away with her lies, "Why I am not sure, what kind of book is it? I don't recall receiving any books that could cause concern."

Twilight blushed and looked away, "Well, it's kind of a book that would entice somepony reading it into doing forbidden things with another pony... it’s a book that I wrote and should have destroyed."

Celestia grinned, "I see, well I can certainly say for certain that I have not read such a book, if I may ask what exactly is inside the book that would cause such actions?"

Twilight turned completely red, "Well it’s... sort of a book that... talks about the habits of the pony... it's written about."

Celestia chuckled, "You display signs of having written something terrible about me, my most faithful student. Please, tell me there isn't some book suggesting I am doing something lewd with my dearest sister... it would be most heartbreaking to know a student of mine would write such a travesty."

Twilight's face fell and she almost cried, "Well... it wasn't meant to be lewd, I just wrote a book that I think I may have wrote while not thinking correctly... I already had to deal with the effects of Rainbow Dash reading her book... and I am afraid of what would happen if the book I wrote about you was read."

Celestia frowned, "I am disappointed in you Twilight, you would really suggest that I would take part in an incestuous affair with my daring Luna?"

Rainbow Dash smelled something fishy, and it wasn't emanating from between any mare's hind legs either. "Wait a second, how do you know what the book is about if you haven't read it?" She asked in anger.

Celestia cringed, "Well... I ... would assume that if Twilight was very afraid of me reading this book it would describe the ultimate taboo in it."

Cadence spoke up at that response, "How do you know it isn't about me and you, and it's about you and Luna?"

Celestia chuckled nervously, "Have I done something wrong, or is interrogating a princess about reading a book so important?"

Shining Armor coughed, "Well, it's just according to Twilight, when Rainbow Dash read the first book that was discovered it caused chaos in Ponyville and lot's of things changed. We are just worried that the book would change you and cause you to do things you wouldn't otherwise."

Celestia chuckled, "I assure you my subjects that I am fine, I have no wicked intent, nor do I desire my sister's flank in any form or way."

Pinkie Pie rushed towards Celestia and looked her in the eye, "Do you Pinkie Promise?"

Celestia was taken aback and momentarily stunned, "I ... umm... well, what does this Pinkie Promise mean?"

Twilight noticed the hesitation, "It means that you ultimately swear you are telling the truth with the penalty of losing one's trust forever if you are lying."

Celestia was nervous and didn't know how to respond and luckily for her she didn't have to. "Are you calling my sister a liar?" Luna asked while appearing before the ponies.

Luna nuzzled her sister and then turned to the crowd, "I don't enjoy hearing my sister being interrogated. If she says she hasn't read some silly book and isn't a deviant then why question her further?"

Twilight was dumbfounded, "Wait... so she hasn't tried touching you inappropriately or even doing anything strange?"

Luna gave a course look and yelled, "No! She hasn't done anything that warrants this kind of treatment, now leave her be or face the wrath of the night!"

Pinkie Pie was enraged, "I know I sent the book here, and if she isn't lying then why didn't she Pinkie Promise?"

Celestia was staring at Luna and not even paying attention to the group of ponies, "Luna, I am sorry my subjects made you lose sleep Please go back to sleep if you can as I escort our guests out of the castle."

Luna chuckled, "it's alright Tia, I am not in the mood to sleep as it's already night time. I shall deal with these ponies why don't you get some rest or something."

Celestia used this opportunity to flee from the scene before anymore attempts to force her to spill the beans could occur. "Thank you Luna, I shall be in my room. You may let me know how the meeting went," she softly said. Celestia began walking off a bit nervously and when out of sight she ran to her room to grab the book.

Luna faced the crowd and dropped the act, "Listen I need to know what exactly does this book do... I am afraid my sister is slowly losing her sanity and is frightening me."

Twilight frowned, "I thought as such... it seems in order for her to get better she has to confront the emotions the book is giving her."

Luna sighed, "so does this mean I have to allow my sister to take me for the night?"

Twilight blushed, "That, or you would have to reject her harshly so she understands it won't happen... ultimately it's up to you to decide what you want to do... I just feel so awful this has even happened."

Luna began crying, "what you ask of me... it's unfair, I love my sister but I don't know if I feel that way towards her. I just can't be the pony to ruin her like this. I will have to think of something but for now please... go back to Ponyville. From now on this problem is mine to deal with."

Twilight looked down and nodded softly. She had nothing to say and started walking away with the group in tow.

Celestia grabbed the book and thought about burning it and hiding the evidence or using her alone time to read it more before Luna eventually came back from her little pow wow. "Well if I begin reading it now I won't think straight tonight when I spend time with Luna... I need to get control of myself... She means too much for me to continue forcing my way into her heart... but the sex... I want it."

Celestia was slowly losing her mind and becoming unstable. She wanted to regain the lost sanity by any means possible and yet her desire to mount her sister and tame that flank was too strong. "The book can wait, I have to prepare myself for my nightly stroll with Luna... I wonder just how far I can get tonight."

She began brushing her mane and letting the natural flow of the hair follicles do the rest to make herself look magnificent. She purred at the image of herself and thought about mounting herself if things didn't work out with Luna. She heard a knock on her door and eagerly invited the pony in.

"Come in," she said with excitement dripping in her voice.

Luna came into the room and with her resolve intact began formulating the plan to either damn or save her sister from eternal despair. "Let's go for a walk tonight... I shall lift the moon and we can have a talk sister," Luna said softly while hiding her emotions.

The group slowly walked away from Canterlot castle and hoped they had made the right decision. Fluttershy was the only pony not to have said a word during the meeting and it was for a good reason. "Hey everypony... I think the book isn't so bad... I mean, if you think about it Twilight, if it hadn't been for your book you and Pinkie wouldn't have found each other... and I wouldn't have my Dashie."

Twilight sighed, "You are right about that, but still, imagine if Spike hadn't found someone else to love and Rarity never did get with Applejack what then? Would that awkwardness kill their friendship, what about Big Mac? He loved you, and if it wasn't for the book you would have been with him. If I didn't write that book then Celestia might not be potentially destroying her career as a princess..."

Fluttershy got angry, "Listen here Missy, you don't even know anything about me... I never liked Big Mac like that, it was always Rainbow Dash, she was always my choice. If Celestia is acting this way it isn't because of some book. The book may have brought it out but it was always there... You think you and Pinkie just had random sex and became lovers? You two have always had this connection... just like Rarity and Applejack... The book may have been the best thing you have ever written."

Twilight grew silent, she wasn't sure if what Fluttershy was saying had any validity to it. She only knew that she was causing Celestia, her mentor, unneeded stress and deviant desires.

Rainbow Dash looked into the night sky as the moon rose high, "it seems whatever happens now it's out of our hooves, plus I think Luna is pretty capable of doing the right thing. In the end it will be their fate not ours."
