It was another day at canterlot as the ponies were all doing whatever they needed to do for the day as some of them would look up in the sky and see that one moment the sun would be up and then as the sun sets the moon would rise up and the sky will be blissed with the night light as the night was out a guard trotted up to Celestia as she watched an two unicorn stallions leaving the throne room.

“Your Highness, that’s the last one for today. What will you do while you wait for Miss Sparkle’s arrival? He informed.

“Thank you for your service, Sun Strider. I’m looking forward to speaking with my student face to face again. She seems to have made a great discovery, possibly the greatest in the history of magic, and wants to discuss it with me and my sister. As for now I think will use this time to spend with my sister. Will you begin making preparations for her court?”

“Understood princess. Good day and goodnight.” The pegasus stallion turned to the other guards in the throne room and started giving orders to them for the nightly redecoration of the throne room.

Princess Celestia trotted off at an easy yet comfortable pace admiring the beautiful hallways of the castle watching the servants and guards walking around on whatever business they had as she was enjoying the peace and tranquility of the inner parts of the beautiful castle. Luna cracked open a sleepy eye and judging by the sun’s position, it was early evening. Which meant she would have some time for herself before she had to prepare for her court and her sister would be busy for a while longer.

Nopony else would have a reason to see her at this hour. Although she would not wanna be disturbed, Luna shifted into a comfortable position lying on her back and started softly rubbing a forehoof between her hind legs, drawing pleasure from the sensation of her pussy against her most sensitive area, Letting a small moan escape from her lips, she gradually increased the intensity of her self-stimulation, not really caring that her hoof was getting wet it just added to the sensation to her pleasure. She could feel the pressure within her building up, steadily approaching a much desired release until….

*Knock knock knock* the knocks on her door as she knew that it was probably her big sister coming in and waking her up.

“Sister? May I enter?” And with a frantic expression and almost flushed look on her face, Luna pulled her hoof away and tries to hide her recent experience as she get in a more “decent” position and calls for her sister to come in, hoping she would leave quickly and not notice what’s been going on seconds prior.

Celestia stepped into Luna’s bedroom, sniffing the air and looking over at her sister, who had three of her four hooves out as the fourth one is underneath her. “Luna? What were you- Oh”. A slight blush graced the princess face as she knew that she was doing something in her own time. “I-I didn’t mean to disturb you sister, I-I just had some extra time off, and I thought we could spend it together.. But I’ll just find something else to do, unless you...”

Her blush deepened more as Luna’s ears perked up. “Unless I what, sister?” “Unless you would like for me to join with you sister?!” Celestia blurted out, her face redder than ever. Luna closed her eyes and smiled softly as this disturbance might actually turn out to be a good thing for the princess of the night.

“Actually, I would love that dear sister.” Luna slowly licked her lips and then licked along the length of her sister’s horn getting an arousing groan in response from her big sister. The white mare was lying on her back, fully exposing herself for her beloved sister, who was taking her sweet time teasing the aroused princess like she was a toy.

Finally Luna slipped her hoof down between Celestia’s legs and started gently it rubbing her pussy. The moan she got in response nearly made her give in to her urges but she kept them in check, and continued at her painfully and teasingly slow pace.

It was not often Luna could be in control of her sister and she wanted to enjoy this rare opportunity to its fullest. She gently bit Celestia’s neck, causing the most erotic whimper she had ever heard come from Celestia as she found a new spot and bit down a little harder, drawing out the same reaction but much louder.

Celestia wanted more and those bites had felt so good to her. She had no idea her sister, was that gentle with a soul at heart but could be so rough but she certainly wasn’t complaining but all of a sudden she stopped? “Don’t stop... Harder... Please!” she moaned to her.

Hearing the need in her sister’s voice, Luna couldn’t help but give in as she bit down again, hard enough to draw blood this time. The speed of her hoof against Celestia’s juicy flower increased slowly as a moan escaped from her lips.

This was the best thing that could have happened to her for the last thousand years, at least. Not only was she being intimate with her beloved sister who had been gone for so many years but that same sister was dominating her, physically hurting her, something nopony had dared for as long as she could remember.

Not being in charge for once allowed her to properly relax, despite the tension building within her. She would be content with lying in this position. However she knew her sister could give her so much more than this simple pleasure. The blissful lusty look in Celestia’s eyes nearly became too much for Luna. She could no longer bear only being the one doing the pleasing as she needed release herself. She gently eased herself down on top of her sister and her own dripping wet marehood making contact with her sister’s.

The thrill of being caught wet-hoofed by her sister and then seeing her moan and writhe in pleasure underneath her had done nothing to do with the lustful feelings that had caused her to rub herself in the first place rather the opposite. She knew she could have teased her sister for a while longer but her own urges wouldn’t stay in check anymore as the time to be gentle is over and she began forcefully rubbing their lower bodies together making Celestia scream.

The scream did not last long as soon as she opened her mouth Luna attacked it with her own sending waves of bliss down Celestia’s spine. The wrongness of the situation they were sisters combined with Luna’s lustful intensity, caused Celestia to peak long before she normally would.

Even as herself was coming down Luna did not relent. The taste of her sister’s mouth and then her increasingly loud moans and body spasms had made Luna lose control completely freeing the sex demon she had struggled so hard to contain. The white mare could do nothing but lie there as her climax had drained too much of her energy

Only barely conscious she felt her sister’s mouth leave hers, and then some shuffling around until her sister’s marehood dripping wet with both sisters juices was pressed against her mouth. Taking the hint from her she slipped her tongue inside the other mare and started gently moving it around her folds.

The feeling was good yet so tame Luna wanted it to be wild. “Harder, sister! Come on!” she screamed before burying her own tongue inside her sister to show her how it should be done.

Despite being exhausted from her previous climax Celestia could feel herself building up towards another. The feeling was nearly too much but she managed to focus enough to increase the intensity of her own licking as she found herself enjoying the taste of her sister’s juices.

Still not satisfied Luna lifted herself off Celestia’s face. “Sister, Bend your head forward. Now!” she commanded with a slight hint of the Royal Canterlot Voice making Celestia unable to disobey. Luna impaled her dripping hole on her sister's horn, before letting herself fall sideways onto the bed.

Celestia started pumping her horn obviously not fast or hard enough according to Luna’s screams as she also fired up her magic, making her horn vibrate inside her sister. The unusual feeling of a tight marehood around her horn made it difficult for Celestia to properly control her magic or indeed focus on anything at all besides the pleasure.

After what had felt like forever Luna peaked, soaking Celestia’s horn and face, screaming in the Royal Canterlot Voice. Celestia briefly wondered if Luna had soundproofed the room, before the flesh repeatedly clamping down on her horn caused her to reach a second peak.

Luna is still full of energy, way too full, turned around and kissed her sister again, forcing her tongue into her mouth and she slid one forehoof down to her sister’s marehood, and one to her own, and started rubbing both. Celestia knew that with the intensity of her two previous orgasms, a third one would leave her completely exhausted and nonfunctional but at this point she simply didn’t care. Her sister’s lustfulness was apparently contagious and she wanted her.

Without breaking the kiss the elder sister rolled the younger onto her back, placing herself on top for once. She roughly smacked the other’s flank, drawing a yelp and muffled moans reminiscent of her saying “Harder, harder”. She smacked it again, before replacing the hoof between Luna’s legs with her own. Knowing what her sister wanted, she rubbed the area roughly, while simultaneously wrestling her tongue, fighting for dominance.

Despite the heat of the moment, Celestia suddenly remembered the appointment she had with her student. The guards knew that Celestia was in her royal bedchamber and she would surely relay the information to Twilight who had the habit of walking in without knocking. And she would arrive any mi-

Celestia’s thought was popped as her third orgasm washed over her, numbing her senses and leaving her panting, exhausted from the sheer pleasure inside her veins. She fell down on top of her sister, who quickly wiggled her way out from underneath her. Celestia opened an eye seeing first the crazed expression of lust on her sisters face then following her sister’s gaze, Her sister’s shouting brought the entrancing alicorn out of her daydream. Shaking her head to get rid the last webs from her mind as she turned to Celestia.

Both mares entered what could only be described as ‘the zone’. A place where the seriously strange and fucked up situations in their minds were that was to be so impossible to imagine it rendering both of the mares unable to even form a basic coherent sentence between them though eventually someone would draw away from ‘the zone’ and speak up and it just so happened just as Celestia opened her lips to speak.

“You know all well that this is just romantic love not just family love sister,” Celestia said as she rolled her eyes.

“Mhmm, who said I wasn’t up for it?” But before Luna could react her sister leaned in and pressed her lips against hers. Luna opened her mouth to scream but found herself muffled as Celestia seized the opportunity and slipped her tongue into her mouth. The two hung there for some time suspended by shock, lust and passion while lip locked together. Luna’s mind had pretty much exploded into an incapable husk of rational thoughts leaving her as Celestia started thinking for the both of them as in her mind.

“Mhmm... This is nice. I should’ve done this sooner. Lulu’s a nice kisser.” She said to herself.

Finally pulling away from her as she was leaving a thin trail of saliva dangling between their lips. “Falling in love with others will only lead to heartbreak sister. But I on the other hand will never leave you,” she said with a giggle.

Her sister on the other hoof was not faring well as her eyes contracted different sizes and her hair usually was normally caught in a non-existent breeze but now hung limp at her shoulders with a few strands on her hair bent or curled like broken strings on a violin.

Celestia waved a hoof in front of her sister’s thousand-mile stare as if she had seen a ghost in front of her. “Lulu? Are you alright?”

The burning train wreck that was going inside Luna’s mind somehow managed to reply with, “You. Y-You. Kissed me.”

The sun princess stifled a giggling laugh. “Yes I did, Did you enjoy it?”

“I- uh- well- you. Just kissed me. Your sister.”

“For a pony who is so reliant on using her royal canterlot voice I must say you really are tongue tied right now aren’t you sister?” When she received only a small nod in reply to her the elder sister sighed softly before moving alongside her shocked sister and drap a wing over her.

“Lulu, I want you to feel that same glorious thrill that comes with loving a pony romantically. But I don’t want you to feel any of that pain that comes with losing your special somepony. But maybe you can find it in your heart to give me a chance?” She gives her the best attempt at pleasing as well with her batting her eyelashes and musters a big set of puppy-dog eyes that she could do. Luna sat there eyes darting furiously as her mind slowly reclaimed her thinking skills and says.

“Y-You and me... T-together... Isn’t t-that incest?”

Celestia shrugged and rolled her eyes. “Well, yes. But it’s not technically illegal, just frowned upon in certain company.”

Luna was torn about this because she really did love her sister more than anything else in the whole world but that glaring word incest cut deep into her mind as the thought of it alone put a bad taste in her mouth. What would the citizens think if they came out as an incestual or princestual couple? But they might just muster up the nerve to depose them from their rule!

“Don’t worry about anypony else Lulu,” Her sister piped up as if she could read her mind.

“We’ll keep this strictly between us and let nopony know.” Her mind was still half-broken from the kiss and her weighing options. On one side of her mind it took the form of her sister smiling joyously as she accepted her offer. But the other took the form of a torch-wielding mobbing commoner storming the castle to seize her from power.

“Well?” Princess Celestia was finally showing the slightest hint of impatience from her voice. But finally the darker alicorn nodded her head slowly. “I-I think I would like that.” A furious blush crept onto her face as it was sticking out like a sore hoof against her rich blue coat.

“Just one thing though tia.”

“Yes?” Celestia said as she was wondering what Luna wanted.

“Could we... Kiss, again?” Luna said as she still had that blush on her face.

Celestia giggled and smiled warmly as she drew her sister closer. “I couldn’t imagine anything better. I will always love you Lulu and I won’t be going anywhere anytime soon as long as I have you right here.”

“Indeed you cake eating princess.” Luna said as she holds Celestia tight and speaking of cake her horn glowed a sun like yellow as a piece of cake appeared in front of Lulu as she smiled a bit.

“Want some?” Asked a nervous Celestia, making light of the situation as she attempted a chuckle.

Luna regarded Celestia with a tilted brow and then, with a sigh, she rolled her eyes and sauntered over towards the bed and more pointedly, towards Celestia. “Alright, fine, but this does not make up for the cake you stole from me before.”

Celestia whined. “Oh come on, Lulu! I didn’t mean to—” without warning, Celestia muzzle was a hoof that had some cake pieces on it as her lips was covered in cake as a royal guard barged into the room.

"Your highnesses are you alright? You were both gone quite a while before and we need for you to do the lowering the sun."

Celestia giggled as she looked at the clock to see it was almost time for night court. The pleasure she had gotten made her forget all about the time. She thought for a moment and then gave a warm smile to Luna. After moments of the night court the sisters got up and put their crowns, neck pieces, and shoes back on. They walked out as it was time to raise the moon.

Celestia walked up to the stand and opened her wings out wide. Her horn began to glow as she slowly flapped her wings and lowering the sun as Luna began to raise the moon as her wings open out, her horn began to glow as she slowly flapper her wings raising the moon. Meanwhile the mares, stallions, fillies, and colts all cheered. Celestia walked back to Luna as a royal guard came up to greet them.

"Your in on this too?" The guard returned with four sun guards and five moon guards.

"Alright, good. Follow us please." the girls walked toward their room and on the way there they lifted their tails to show the guards a sneak peak of what they were in for. They all walked in the room and wondered what was going on. The castle maid noticed this and the last thing she saw of the princesses was Celestia put a "Do Not Disturb" sign on the door as she giggled and slowly closed it.

But let’s say that the can make out to be quite the love connection whenever it comes to there bedtime and the princesses are not afraid to get kinky and show there love no matter what as the two will start living there lives with this new relationship of there beginning.
