That night Princess Celestia slept like a baby. It was never clear for her if it was because of the great fun she had or because of her sisters magic. Either way she never really cared too much. When Celestia finally woke up it was all calm and quiet, like nothing that she remembered from the day actually happened.

"Could... Could all of that have just been my imagination?" Wondered Celestia. She got hit with cold sweat from being worried if her mind was screwing with her again.

After a few more minutes of panic, Celestia realized that there's nothing to be gained in laying in bed and questioning her sanity. It was still dark, but she needed to get out of bed and get started with her morning routine such as brushing her mane, making breakfast and raising the sun. She even thought about getting some "me time" after all that was done.

Suddenly an unknown force takes a hold of Celestia's limbs. It starts stretching her to every side, it felt like she was being tortured. Slowly her limbs started getting tied with rope right to the bed. Celestia kept getting restrained tighter and tighter. While she continued to struggle a ring floated up to her horn and dropped down on it. The ring radiated a seemingly harmless, yet sinister aura.

Finally everything goes quiet again. The only sound in the room was Celestia struggling to unbind herself from the bed. Trying to use her magic didn't work, neither did using force. For the first time in forever Celestia felt helpless, everything she did was pointless. While she found it absolutely frighting, she did also find it strangely arousing.

The door to her room slowly opened. A dark shadowy figure entered the room. For any normal pony the figure would be a mystery but not for Celestia. Years of fantasizing about her sister made her remember every single detail about her body, even the way she walks and from that Celestia could easily tell that the pony was indeed Luna.

"Oh thank you for coming, sister! I could really use your help! Something attacked me and for some mysterious reason my magic is gone." Said Celestia relieved knowing that she isn't alone anymore and that she has a better chance of getting out of her predicament.

Luna slowly crept closer to Celestia, stepping out of the shadows into the dim light in Celestia's room. As the light shined over Luna's face, a smug grin stretched across it. "I would get you out, but there is no fun in that. The ring on your horn voids your magic, that's why you aren't able to use it. And don't worry, my dear sister, you won't need your magic for what we are about to do."

"Luna what are you talking about, snap out of it!" yelled Celestia, still being completely lost about this whole situation.

"Don't lie to me, I can see you are exited" - Luna brushed her hoof over Celestia's marehood. - "You are wet as a river."

"What are y-" Celestia was interrupted by Luna pushing a ball gag into her mouth.

"Sometimes you just talk to much," Luna stated. "Let's have some fun!"

Now Celestia was totally powerless to do anything, and her entire fate was in her sisters hands. She couldn't move, couldn't use her magic, she tried yelling, but the ball gag only let her squeal. Luna found her squeals to be really cute.

"Oh, before I go, I brought a gift for you." Luna turned around, showing Celestia her rectum. She had a butt plug inside of her, which she slowly pulled out, letting out a little sight and enjoying the stretching, and put it into Celestia.

The butt plug wasn't that small and combined with the fact that Celestia was still sore from the events of the previous day the butt plug hurt a lot forcing Celestia to squeal even more.

As Celestia calmed down Luna took a black piece of fabric, blindfolded her and left the room. For some weird reason Celestia kept getting more and more aroused by everything that was happened. There was something about feeling completely helpless that was turning her on.

Celestia didn't know how much time has passed, it could have been several minutes, it could have been several hours. To Celestia's surprise the butt plug that was currently stretching her insides wasn't a normal one. It suddenly started to vibrate causing her to start getting even more wet than she already was.

Her intense desire to play with her dripping hole grew even further, but she couldn't do anything about it. That feeling ended up turning her on even further. At that moment she couldn't think about anything else then how to get her pussy rummaged. Out of nowhere the door opens again and Luna comes back into the room, bringing some more toys in.

"Well, look what you have done, you got the whole bed wet!" Luna said. "We can't have you go unpunished now, can we?"

Luna pushed a large dildo into Celestia's moist passage. This was just the thing that Celestia needed and, even thought it was too big for her and it painfully stretched her insides, it felt amazing. Every time Luna moved it inside of her, Celestia let out a moan, that even thought was muffled by the ball gag, was load. It didn't take long for Celestia to start feeling pressure in her loins and let out all her juices.

Luna quickly pulled out the dildo out of Celestia and licked it to have a taste of Celestia's nectar. She quickly pulled out the ball gag and pushed the dildo down her throat. "Be a good sub and clean it."

The dildo stretched her throat a lot. Celestia was gagging on it, but she couldn't do anything about it, her sister was in control now. Luna pulled the dildo out of Celestia's mouth and before she could grab her breath back, Luna put on the ball gag on her again. "Good girl! I think you deserve a reward."

Luna leaned down to Celestia's crotch and rubbed her muzzle into her pussy, making Celestia excited again. She started licking it as slowly as she could, teasing Celestia. And then when Celestia least expected it, Luna pushed down her tongue as deep as possible and started messaging her inner lips. It didn't take long for Celestia to get close again, Luna's mouth got quickly filled with wetness.

"You know, your horn is pretty big," wondered Luna while pulling out from eating out her sisters pussy.

Celestia got completely lost, she didn't understand what could Luna have meant by that. But her state of being lost didn't last for long as she felt Luna climbing over her head and slowly starting to mount her horn. It didn't surprise her that much to find out that her sister was also dripping wet. The deeper Luna pushed Celestia's horn into herself, the better it felt. Luna started moaning softly as the horn continued to penetrating her. Suddenly Celestia felt a weird liquid drip down and cover her forehead, there was no doubt in her mind about what the liquid was.

Luna got off Celestia, all satisfied with what she has done. She finally removed the ball gag from her sisters mouth and removed the blindfold.

"That was probably... One of the weirdest and best experiences I had in my life." mumbled out Celestia, still having a hard time talking from the ball gag.

"I'm glad you enjoyed it as much as I did" said Luna, while untying her sister.

When Celestia got free she got out of bed and stretched. Luna remembered that she still had her butt plug inside of Celestia. When she tried to pull it out Celestia stopped her. "I still have a whole day ahead of me. And I need something to pass the time."

Both of them let out a childish giggle. Before heading out and letting Celestia get on with her day, Luna got close to her and slid her tongue into her sisters mouth. She suckled on her lower lips before finally letting her go. "I love you so much, my dear sister."

Author's Note

I'd like to sincerely thank everyone who actually spent time out of their day to read my work, it truly means a lot to me.

I'm about to do some self reflections so if you are at all interested in a few of my thoughts I'd urge you to continue reading.

Before doing this, I never considered how much work goes into writing these fanfictions. I've gained a lot more respect for everyone willing to do this.

In the middle of writting I wanted to give up on this project, but I'm glad I stuck with it, even if it isn't a good fanfic. It's a new experience in my life and I'm glad I set out to do it.
