The Truth About Alicorn Sisters

After Celestia learned about Luna's relationship with Twilight, she reminded her younger sister of a bet they made long ago. Considering that she is Luna's marefriend, Twilight decided to head to Canterlot and join them. Once they arrived they headed straight to Celestia's sleeping chambers where she promptly locked the door. She smacked Luna's flank with her tail and asked, "Well Lulu, shall we get back to the fun we used to have so long ago?"

Before Luna could reply Twilight asked, "About this fun, what is it? You said on my balcony that Luna liked it, I want to know exactly what it is."

Luna replied, "Twilight, to truly understand it thou wouldst have to understand the close nature of natural born Alicorn sisters."

Twilight asked, "Close nature?"

Celestia began, "Yes Twilight, close nature." She cleared her throat and continued, "Here is the thing, given that there are so few Alicorns in this world, much less natural born ones, pretty much nopony knows about the true nature of Alicorns and the bonds they forge when they are young."

Twilight asked, "So what kinds of close bonds do they forge?"

Luna replied, "Well in the case of Alicorn brothers, while they do care for one another, they fight one another to the death over territorial control. As time passed, their aggressiveness only became worse until they would kill each other. Eventually all the male Alicorns killed one another, leaving only females and thus, nopony to mate with."

Celestia added, "And when it comes to Alicorn sisters, once they come of age, they become very needy and lustful of one another."

Twilight asked, "So natural born Alicorn sisters...."

Luna replied, "Yes Twilight. The moment both sisters come of age, a special bond forms between them. They develop a bond of sexual desire for one another. With some it is only moderate."

Celestia interrupted, "But in the case of Lulu and I, it was extreme. There would be times when we would lock ourselves together in the same room for days at a time and engage in activities that most ponies don't even dare think of, much less speak of."

Twilight asked, "So incest is natural for natural born Alicorn sisters? You don't see anything wrong with it?"

Luna replied, "Twilight, it is part of our biology. No pair of Alicorn sisters was ever known to not develop this bond. It is one of those things that once the bond develops, it is eternal. The sisters will always desire one another, they will always be intimate."

Celestia added, "Even if they do find a mate at some point in their life, they will always desire their sister and find ways to have trysts with her."

When Twilight heard this, she was shocked. This was something that she simply could not wrap her mind around but then she realized one thing, that they weren't like that. She asked, "Celestia, Luna, if that is the case then why aren't you two like that anymore? Why don't you lust for one another anymore."

Luna replied, "We are no longer like that because when we became resentful of the ponies shunning our lovely night, we became Nightmare Moon. In a sense, we became a different pony with a different mindset. Yes we were still biological sisters, but we had become something else and that lustful bond was shattered."

Celestia added, "When she became Nightmare Moon, her desire went from being me to having full power over Equestria."

Twilight asked, "And I take it that when Luna returned from the moon, the bond did not return?"

Luna replied, "No, it didn't. While we did return to our former self, the bond never reformed and it will never return."

Twilight sighed in relief, "So I don't have to worry about you leaving me for Celestia or even if we were to become a committed couple, I wouldn't have to put up with you having to be intimate with Celestia?"

Luna replied, "No Twilight, you won't."

Celestia giggled, "Oh I wouldn't be so sure about that Lulu."

Celestia's response and the seductive looks she was giving Luna made her heart sink. While Luna was not giving Celestia the same seductive looks, deep down she had a feeling that Celestia would cause that bond to reform one way or another. Celestia swatted Luna's flank with her wing and continued, "Well Lulu, let's relive the old days, shall we?"

Luna sighed, "Tia, thou knows we are only doing this because we lost that bet, right? Thou can try as hard as thou wishes but thou canst cause that bond to return. Our true love is Twilight and nopony else.

Celestia giggled, "Oh Lulu, you're so adorable."

A Second Chance

Despite Luna saying that nothing would cause that sisterly bond they once had to return, Celestia had other ideas. Twilight certainly hoped that nothing would cause the bond regarding Alicorn sisters she learned about to return. After contemplating exactly what she was going to do for a couple of minutes, Celestia pointed one wing at Luna and the other at her bed and ordered, "Lulu, lay down."

Luna gave Twilight a nervous smile as she did what was ordered of her. Celestia crawled on top of her and chuckled, "I've waited over a thousand years for this Lulu, I hope you're still as good now as you were then."

Luna sighed, "Please Tia, canst we do something else, something that wouldn't make us feel like we're betraying Twilight?"

Twilight interrupted, "Luna, you're not betraying me. You made a bet and I understand."

Celestia laughed, "Alright then." She smiled at Twilight, "You know, eventually you can join us. A third will make this all the better."

Twilight replied, "I'll think about it."

She wrapped her legs around Luna and began to kiss her. While the kissing felt good, she wanted more so she began to grind her marehood up against that of Luna. She moaned, "Oh Lulu, I've missed this so much."

Luna did not say anything as she was trying her hardest to just get through the grinding without breaking. While Celestia would never admit it to Twilight, she wanted to destroy the relationship her sister had with Twilight and have Luna solely as her own. She wanted things to be like they used to be, she wanted her and Luna to do everything they used to and most of all, she wanted that bond back.

Once she finished grinding on Luna, she sat up and began to lower her marehood towards Luna's face. Celestia saw Luna begin to move and ordered, "Lulu, stay still. Remember, you owe me!"

Luna begged, "Please big sister, we love Twilight. Wasn't the grinding and kissing enough?"

Celestia did not answer at first. She lowered herself lower and lower until Luna teleported herself over by Twilight and cried, "No big sister, we canst bring ourselves to do this. We love Twilight and no other. There hast to be other ways to bring happiness to thee."

Celestia looked at her sister and while she saw anger in her eyes, she saw the anguish in Twilight's eyes. She decided she would give Luna one chance to avoid this. She said, "Lulu, I will give you a chance to avoid this. You must make me a cake. If it is the absolute best cake I have ever ate in my life, that will be it. You won't have to fulfill what the terms of the bet are" she then got a huge smile on her face and continued, "but if it is not the best cake I have ever had, not only will you have to fulfill the terms of you losing the bet but you will have to do more for me."

Luna asked, "What else would we have to do."

Celestia walked over to Luna, swatted her flank with her wing and continued, "You will be my sex slave for a year, following the month you owe me." She began to caress Luna's clit and continued, "You and I will lock ourselves in my sleeping chambers for that whole time and you will not be allowed to see Twilight, it will be just the two of us and nopony else."

Twilight gasped, "Seriously Celestia? You would do that to not just her but me as well? You would keep a couple who loves one another apart like that?"

Celestia replied, "Yes. Trying to get out of losing a bet with me can have it's rewards if you make me happy, but if not, the punishment can be tough."

Luna asked, "But big sister, who will raise the sun and moon? What about us eating?"

Celestia replied, "We can do that from in here and we will have our meals delivered to us." She began to giggle, "But face it, our meals will consist primarily of each other!"

Luna stood confident and replied, "So be it big sister. We shall head to the kitchen and make thee the best cake thou hast ever tasted."

Celestia said, "Alright," She saw Twilight begin to follow her and ordered, "Twilight, you will stay with me. I do not want you helping her and besides, I want to talk to you anyway."

As Luna closed the door behind her Twilight replied, "Alright, but I do want to talk to you too."

Celestia sighed, "Alright, but if it involves your relationship with Luna, if this cake isn't the best, it won't matter."

Twilight grunted over her comment. She knew that this situation was completely out of her hooves. While Celestia had always been honest with her and she trusted her former teacher completely in the past, she couldn't help but wonder that even if Luna made her the best cake she ever ate, that she wouldn't lie about it just so she could engage in the sexual activities she desires so much.

A Wonderful Ending

While Luna was in the kitchen, she was searching through the cupboards looking for exactly the right ingredients. She knew that if she were to fail in making her sister the best cake she ever tasted, that she would be relegated to a role that she considered disgusting and demeaning, the role of a sex slave.

Once she had found all the proper ingredients she headed to the fridge to get eggs and milk. As she started to mix it all together she said to herself, "Just you wait Celestia, this will be the best cake you ever ate and you will let me be with Twilight."

Once she finished making the mix she poured it into a pan and placed it in the oven. She began to pace back and forth hoping that it would meet Celestia's requirements. She began to sweat she was so nervous, "Luna, everything shall be ok, our sister shall love it."

In Celestia's sleeping chambers things between her and Twilight were tense. Twilight asked, "Celestia, you said that if Luna doesn't fix you the best cake you ever ate that she would be your sex slave. You aren't really serious about that, are you?"

Celestia replied, "Actually Twilight, I am. She lost a bet and while you may think it seems harsh, I can't let her get out of this and besides, I have waited over a thousand years for this. I have waited so long for our sisterly bond to reform."

Normally Twilight tries to remain calm in most situations, this was a time that she simply could not remain calm. She snapped, "Celestia, I know you have this desire to take Luna as your own but that isn't happening. She loves me, not you. I just wish you would get that through your head."

Celestia hung her head, "You're right Twilight. I look at things and I realize that perhaps I have been going a bit overboard," soon she began to smile, "but that still won't keep me from either having my cake or having my Lulu."

About an hour later the two heard hoofsteps rushing towards Celestia's sleeping chambers. It was Luna carrying a chocolate cake with her. She presented the cake to her sister, "Big sister, here is thy cake. We hope thou finds it most delicious."

Celestia lifted the cake to herself, "Well we'll see. I must admit, it does look delicious but what matters is how it tastes. If it doesn't taste good, you know what will happen!"

Luna sighed, "Yes we know what will happen but we dost not have to worry as thy cake will be the most delicious cake thou hast ever tasted, we promise."

Celestia sighed but then took a bite of her cake. She couldn't believe it. It was by far the most delicious cake that she had ever eaten, it was one of those cakes that simply couldn't be topped. She shouted, "Luna, this cake is beyond delicious! How were you able to make it just perfect?"

Luna replied, "We just found the right ingredients to add to it." She got a huge smile on her face and continued, "We take it thou finds thy cake acceptable?"

Celestia shouted, "Acceptable? Acceptable? This cake is far better than acceptable, it is the best I have ever eaten."

Twilight heard their discussion and interrupted, "Celestia, I take it that Luna doesn't have to 'pay up' as you put it?"

Celestia replied, "No Twilight, she does not." Luna stepped over by Twilight and put her wing around Twilight. Celestia continued, "I'm happy for you two. I'll be honest, I didn't think Luna could make this cake so good" she cast her gaze at Luna and continued, "But there is one little thing that I ask of you."

Luna sighed, "What is that big sister?"

Celestia replied, "I simply want you to give this recipe to the cooks. This is the best cake ever and I want lots and lots more of it! You know me, if there is one thing I can't get enough of, it is cake!"

Twilight asked, "So I take it that Luna can leave with me?"

Celestia began to gorge more on her cake, "Yeah, she can go with you."

Twilight and Luna began to celebrate as Celestia remained more focused on her cake. Luna took a look at Twilight and said, "Well Twilight, shall we get going? I really want us to just spend some time together. I want to get this whole situation put behind us."

Twilight replied, "As do I. Let's get going, let's pick up where we left off and move towards a wonderful future together."

Luna and Twilight were finally happy. After nearly having to submit to Celestia for a year, Luna was as happy as she could be and after Celestia nearly took Luna from her, Twilight was ecstatic. Now the two could focus on what mattered most, and that was each other.
