Hidden Desires 3: All or Nothing

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.
