Its been a few hard years for Princess Celestia. Ever since Luna came back from the moon she has been feeling strange. Every time she sees Luna around her mind goes wild, usually losing the ability to think rationally. For a while it never occurred to Celestia what it could be.
As the years went by Celestia started to have sexual fantasies about her sister. Every one more perverted then the other.
"This is wrong," Celestia kept telling herself. "You can't possibly be thinking about your sister like that!"
But the disgust didn't stop her. After a while she started getting off to the thought of being with her sister. Having fantasies about spending the night in a private place fooling around together. With each passing day, her lust grew stronger. She wanted her sister and wanted her bad.
This day was a day like every other. After a hard day of ruling Equestria, Celestia needed some time off to relax and unwind. She went into her bedroom and laid down on the bed. She spread her legs and slowly started rubbing her wet privates. She needed nothing more then the thought of her sister to get off.
With every rub she could feel herself get closer and closer. Her right leg starter to vigorously twitch. Strong waves of pleasure started passing through her body as she was thinking about her sisters beautiful behind. Celestia bit her lower lip in an attempt to not moan out load and possibly get caught. As she starter to rub faster, she wasn't able to hold it in anymore. Her she could feel her cavity start to burn as her marecum was about to burst out.
"Luna!" Celestia moaned out as a strong wave of pleasure hit every part of her body.
Celestia didn't move anymore. She was soaking in every last bit of pleasure she got. So there she was laying in her marecum, unwilling to move, and unable to think anymore like her whole brain was just void.
"Ugh," Luna groaned as she was walking to Celestia's bedroom. "What does my sister want now?"
As Luna was about to open the door to her sisters bedroom, she smelt a strange odor coming from the inside. Not thinking much of it, she quickly pushed the door in. "Sister, why do you always have to shout for me and you can't just come ask me for something..."
Luna just stood there in shock, it took her a few seconds to grasp what she was seeing before her eyes. "I'll just go..."
"Wait..." said Celestia as she snapped out of it. "Please give me a minute to explain,"
As Luna continued to stand there in shock, Celestia noticed something. Her sister was not only blushing but the was something dripping down Luna's leg.
"You feel it too, don't you?" mumbled Luna.
"Feel what?" Celestia quickly responded.
"Oh don't play dumb with me, sister." Luna smirked as she started walking up closer to Celestia. "You spend several years looking at me funny, sometimes even staring at my flank. And now you yell out my name while masturbating?"
"I promise you Luna, its not what it looks like..." muttered Celestia.
"Celestia..." whispered Luna as she laid down right next to her sister. They both felt the warmth of each others bodies as Luna wrapped her hooves around Celestia gripping her tightly. "I don't think there is a more opportune moment to tell you this... I love you. I want us to be together."
"We shouldn't... This is wrong" worried Celestia
"If its so wrong, then why do we want it so much?" Luna interrupted her sister
With a seductive look, Luna leaned in closer to her sister, giving her a tender and passionate kiss. Sliding tongues against one another.
Luna pulled her head back as Celestia was trapped in a trance. She couldn't believe that her wildest fantasies were finally coming true.
"I've always wondered what you taste like," uttered Luna as she circled her legs around Celestia's head. She leaned it to have a taste of her sisters dripping crotch. Luna slid her tongue into her vagina, and started moving it around like she was giving her a message.
Celestia tightened her hips around Luna's head. It felt amazing and she even started quietly moaning.
"Well , sister. Are you not going to reciprocate?" Luna wiggled her cunt above Celestia's head, letting a drop of her liquid lust fall down on her face.
Celestia pulled down Luna's flank closer to her as she stuck her tongue as deep as she could, wiggling it inside. She made sure to taste every last bit of her sisters inside. Luna started sighing in delight "I think I'm already close!"
"Me too" Quickly responded Celestia as she felt her pussy leak fluids right into Luna's month. It didn't take long until Celestia felt her snout being covered in Luna's arousal. Never has Celestia felt euphoria as strong as this. Shocked by all of this, she blacked out for a moment.
Next thing Celestia knew Luna wasn't near her anymore. She was walking back into the room carrying a inconspicuous box with her.
"Thank you, sister. This has been an amazing experience." said Celestia as she was getting back her grasp of her surroundings.
"Oh, I'm not done screwing you yet!" Luna looked at Celestia giving her a smug face. "Now please turn around."
Celestia didn't know how to respond but she did what her sister asked for. Suddenly she felt Luna getting close to her plot "Sister? What are you going to..."
Celestia suddenly got interrupted by Luna piercing her rectum with her tongue. A sharp pain went through her flank, one like she has never felt before. It was painful, but at the same time it caused her great pleasure. Luna pulled out her tongue, stopped stretching Celestia's anus "Wow, you are really tight. Well no problem, I'm just gonna have to train you."
Luna used her magic to open the box she brought in and pulled out some anal beads "This should work just fine."
"I've never played with that region before." Said Celestia with a shaky voice, still recovering from the tonging Luna gave her. "Please... be gentle."
Luna wasn't listening anymore. All she was focused on was her sisters anus. Luna put the beads in her mouth to lube it and started pushing them in Celestia's plothole slowly and carefully. She made sure to savor every little moan and groan coming out of Celestia.
This was a whole new world for Celestia. She has never felt this kind of pleasur before. It was really painful, but for her the pain made the experience even better. Despite the fact that her pussy wasn't being stimulated at all. Celestia felt an another massive wave of heat coming over her. The closer she got the loader she moaned. As Luna was pulling out the last bead, Celestia's juices began flowing once more, covering the bed.
"Well, looks like someone enjoyed them self's" Luna said with a lowered seductive voice.
"You are giving me all this attention and not leaving anything for your self. Here let me do something for you." Celestia looked down into Luna's box of toys. "Oh I like this one!"
Celestia carefully pulled out a vibrator out of the box. She quickly turned it on and off just to check if its working. She set it on the lowest setting and brought it near her sisters crotch. At first Luna barely felt anything but as Celestia kept ramping up the strength Luna was getting lost in the pleasure. Her moans were way more softer then Celestia's.
"Its nice to finally see you be the one moaning," said Celestia laughing still with disbelief at the recent events.
"Why don't you use that cute mouth of yours to do something actually useful!" said Luna as she pulled in Celestia towards herself for passionate kiss. Luna could feel Celestia's heavy breath as they pulled each other tighter to one another.
By the way Luna was twitching, Celestia could tell that she is close to climaxing. She used this opportunity to ramp up the strength to the the max. Luna couldn't take this pressure directer straight into her core. She let out a huge moan as her juices flowed out on the bed mixing with the ones left by her sister.
For a good bit of time neither of them said nor did anything. They didn't need to say anything after all, them laying there, cuddling, putting their wings around one another, was saying a hundred times more than they would be able to say with words.
"You know what?" – Luna stood up – "There's this one last thing I have always wanted to do."
Luna pulls out a strap on from her box and tightens it around her waist. Celestia stared at Luna's newly acquired shaft "Luna? Wont that be too big for me?"
"Nonsense, sister!" Smirked Luna. "We'll find a way to fit it in."
Luna started slowly rubbing her strap on, on her sisters clit, stimulating it. She made sure Celestia was nice and wet, before she would make her grand entrance. It didn't take long till Luna finally slid in her rod into Celestia's hole as deep as possible right to the base.
Celestia has never taken anything that big in her life. Luna started to slowly move back and forth, taking deep, long thrusts. Every thrust brought Celestia more pain, but most impotently with pain came immense pleasure.
"Don't stop!" Cried out Celestia "Fuck me harder!"
Luna grabbed one of Celestia's legs, lifted it up and held it tightly to her chest, twisting Celestia sideways. She started speeding up, fucking her sister as fast as possible. Celestia couldn't feel her legs anymore. Her vagina started to swole as it ignited with unimaginable heat from all the pain and pleasure she received from Luna.
"I'm cumming!" shouted Celestia as she let out one final moan.
"Well, have you enjoyed yourself, sister?" asked Luna looking down at Celestia who was laying in a bed covered in their liquids.
Celestia didn't answer. She couldn't. Everything that happened today... Her wildest fantasies finally coming to fruition. All Celestia could do anymore was calmly pant. She was tired, from all of this action and felt herself slowly drifting into the dream realm.
"Heh, I see..." - Luna gave Celestia a kiss on the forehead, not one of passion, but of care - "Get some rest. I got something very special planned for tomorrow."
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.
