                      One wild night

One wild night
It was late in the day in Canterlot, and Luna was hurrying back home, for she needed to prepare for her nightly duties as princess. Through the castle and up the steps she trotted, heading for her bed chambers for her regular brief nap before the evening was out. Curiously, she found the hallway to her room was absent of guards, which was curious as she had counted at least four or five of them positioned there before leaving. Despite the slight unease she felt from this, she figured they were changing shifts or on a break. When she opened the door to her bedchamber, she found a very special surprise waiting for her.
Her sister Celestia was there, on her bed wearing none of the usual royal jewelry, rolling around and pretending not to notice she just came in. The sun princess giggled as her illustrious mane thrashed in the air while rubbing her snout all over Luna’s pillow.
“SISTER!” Luna exclaimed. “What in Equestria are you doing here? I thought you were supposed to be lowering the sun!”
A smirk widened across Celestia’s face as she sat up on Luna’s bed, facing her sister. “Well it’s no problem for me, and besides,” she said getting off the bed, “is it so wrong for a princess to want to spend some quality time with her sister?” she asked with suggestive tone.
“N-no, it’s just strange you see you here so late, and naked as well,” said Luna, a bit anxious from how close to her with a seductive look in her eyes.
“Naked? You mean without those dull jewels? I sometimes find it relaxing to get out of them every once in a while,” she smirked as her horn lit up. “Wouldn’t you agree dearest Luna?” she asked as her magic whisked Luna’s tiara, necklace, and horseshoes away and placed them in the corner.
Luna was shocked “Sister, what’s gotten into you?” she asked adamantly. “What is this?”
Celestia giggled, the sun princess was in her heat and wanted her sister bad. “Luna, do you remember that time when Starswirl was away for a long time, and one night we were supposed to be studying, and I caught you playing with yourself?” she asked smirking, ignoring Luna’s question.
“What are you talking about!?” Luna reacted loudly and blushing. She looked before she was about to speak, and she paused. She began to ponder: “Now that you mention it, I do remember something like that...”
“And then I lent a helping hoof as a big sister,” recanted Celestia, slowly allowing the memory to pass in Luna’s mind as she crept just a step closer, bringing her muzzle just inches away from her sister’s. “We played and explored each other for days until old Starswirl came back.”
Luna started walking backwards and stammering. “Celestia, I remember that and I appreciate whatever it is you’re trying to do for me, but the two of us can’t be like that, we’re sisters! And what will the citizens of Equestria think if we were ever found us together in such a way?”
“Nopony will ever know I promise,” she assured Luna, following her backsteps “I just want to be closer to you, for it seems we haven’t connected much like the way when we were younger,” Celestia lamented, keeping her eyes on Luna.
“I understand, truly, but still I don’t think of it as befitting us as princesses,” worried the blushing night princess, unable to take her eyes off her sister.
“Well, we’d hardly be the first royalty to be so intimate with each other, and besides that,” she almost whispered to her as she touch Luna’s cheek, “all we’ve ever had is each other,” spoke Celesia to her beloved sister, before kissing her lips tenderly.
Luna was stunned, she hadn’t expected for her sister being so sexually aggressive. Her mind drifted to those days when they were young and ‘experimental’ with each other’s bodies. Her worries of responsibilities and appearance became started to melt away, and she couldn’t help but think of all the pleasure she felt from the intimacy with her sister long ago, and how Celestia was right. Having lived for so long, the two of them were the only ones who never left their lives. As Celestia’s kiss parted, she mumbled: “I never thought of it that way — perhaps you’re right.”
Celestia smiled, then suddenly Luna returned her kiss and she could feel her sister pushing them forward onto the bed, putting her on her back. Celestia put her hooves all over her sister’s hair and flank and kissed her back. She was ecstatic, overjoyed even, for she’d fantasized about this moment for centuries. She had tried many suitors, but none that made her as happy as her time with her sister.
The minutes the two spent making out felt like hours for them. Had there been anyone been in the hallway, they would hear the faint wet sounds of their lips smacking together and murmuring sweet nothings before Celestia shut the door. They hugged each other tightly, stroking their enchanted manes and everywhere else, all while their lips barely parted. Celestia kicked the air as they kissed, then gripped Luna by her long hindlegs and pulled her sister down beside her.
Luna, unexpecting of this move, squealed as her sister pulled her down, their kiss splitting away with a wet ‘pop’ as a trail of spittle briefly bridged their lips.The night princess stared at her sister with an aroused and yet nervous look. Her body called her to Celestia, but she still worried of the political consequences of sleeping with her sister.
Celestia reached her hoof out and poked her sister’s snout playfully. “Something bothering you, sister?”
“I-I’m still not sure about this,” whimpered Luna.
Celestia pulled herself closer to Luna, “Don’t worry, it’ll be our secret if you want,” she spoke as she planted a kiss on the blue princess’ head. “And best of all, we’ll always have each other, right?”
The night princess nodded, “Right.” She looked as if she was about to speak, and then began to moan.
Celestia wedged a hind leg between Luna then began rubbing her knee against her already damp vulva. She slipped and slid against her wet royal pussy as she held her sister close by her big flanks. “Don’t worry, big sis has gotcha,” she assured her dear Luna, whispering hotly in her ear.
Luna hugged Celestia tightly, moaning as she felt her knee pushing deeper into her sensitive snatch. She was pudding in her sister’s hooves as the more experienced mare pushed her marehood’s sweet spots.
“You’ve been so stressed lately. You should just relax and let your me take care of you,” she continued to whisper in Luna’s ear. She kissed her cheek, as her knee drilled into Luna and holding her close, sending into her first orgasm from another pony in over an eon. Celestia watched her sister’s face as she came and moaned; that was music to her ears. “That's it, just let it all out,” she said right as she kissed the night princess's neck.
Luna cried out in ecstasy, clinging tightly to her sister. She felt a growing pleasure and warmth passing over that only her loving sister for over millenia could bring her. Though she had to suppressed them earlier, her thoughts and lust of Celestia became overwhelming in just a brief span of time.
Some time had passed and Luna was laying on her back with her legs spread wide as Celestia laid right on top, draped over belly to belly like a blanket. Their clits rubbed as the sisters kissed again and again while murmuring into the other’s mouth.
Celestia gave her sister a nudge from her groin, getting a squeak out of Luna as their clits nudged one another. “You are just as as you were centuries ago,” Celestia said giggling some.
Luna paused upon catching her breathe, then spoke, “I love you sister.”
“I love you too,” Celestia said as they shared a kiss once again. They kissed for a long time before the sun princess raised her head up, her horn lighting up in a golden aura. “Now, we’re gonna have some real fun,” she grinned.
Celestia magically opened a box with her mark on it. She floated two shiny stallion shaped toys out of the box, sending them over to the sisters and stopping just short of their pussies, each tip just barely touching the vulva.
“Get ready,” Celestia said stroking her sister’s starry mane, kissing her forehead at the base of her horn. “Remember we can slow down anytime you like.”
Luna nodded, then let out a soft ‘Ahhn’ as she felt the shaft pushed passed her still soaking wet marehood half way in. She clungto her sister’s body as the toy penetrated her deeper. She moaned with her sister in the shared feeling of being penetrated.
Celestia craned her head down to Luna and started kissing her neck hard. Her magic pushed the toys deeper inside them, the wet slapping sounds of the thrusting length and the moaning, filling the room along with the scent of the sex. She used her magic to strongly vibrate the thrusting shafts deep inside them, and her legs began to shake while Luna’s body quaked beneath in pleasure.
“Ohhh, oh, oh sister! That feels so good!” Luna cried out. “Don’t stop!”
Celestia pulled her head up to see her sister’s face, her tongue lolling out as the toys thrusted into her tightness. When she looked up and noticed the moon outside was swerving in the sky she panicked. “Luna! Luna dear,” she tried to get her sister’s attention. She ceased the vibrations and slowed things down for a moment, “you’re shaking the moon.”
“Huh?” Luna almost moaned, before looking up out the window “Oh,” as she steadied the moon, nervously laughing it off.
Celestia laughed along “Not your fault, I shouldn’t have vibrated them so hard. I’ll try to dial it back some,” she apologized. “Now shall we continue?”
The two regal sisters returned to lovemaking, kissing and moaning as Celestia worked her magic with the vibrating shafts thrusting, eventually reaching their cervixes. Their huffing and wailing escalated as both began reaching their climax with their toys thrusting deep inside. All the pleasure made Luna’s hooves begin to curl.
“Ahhhh, I feel I’m coming again, sister!” Luna shouted.
“Let’s come together,” Celestia responded, as the two kissed once more.
They hugged each other tight, rejoicing in their shared climax, moaning into each other’s mouths. Their juices dripped and splashed on the sheets below as Celestia thrusted the lengths all the way in. The sun princess landed on her side next to her sister, then draped a wing across her. The two gazed into the other’s eyes catching their breath as Luna caressed Celestia’s cheek.
The night crept on as the two canoodled, until Luna began to break away and walked towards the window facing the night sky. “I really should be spending time looking after ponies’ dreams,” said Luna concerned.
Celestia got up and walked toward her sister “I think they can manage just one night without you,” she said, resting a hoof on Luna’s shoulder. “After all, we have to take care of you too, right?”
Luna smirked, chortling a bit, “I suppose, though it does seem rather selfish.”
“Well not at all. You’ve been working so hard since you came back, it would be very imprudent for you not to take some time off,” she assured her sister before giving her a quick peck on the lips.
“It has been nice,” Luna blushed, “I didn’t realize I missed us being, so, intimate until tonight.” She put a hoof on Celestia chest, “Thank you sister.”
“No need to thank me, the pleasure is mine to share,” the sun princess responded rubbing her cheek against Luna’s, and the two nuzzled together.
Soon they were at it again, sitting with their hooves folded and bottoms partially in the air. Both held the shiny dildoes with their magic, thrusting into the other, staring into the other’s eyes as they sent each other orgasming several times.
“Ahh ahn, coming again,” moaned Luna as she climaxed again, “starting to get a bit light headed.”
Celestia nodded “Maybe we’ll just let you take over mine then,” pulling her toy from Luna’s marehood, soaked with her juices.
“R-really?” Luna said taking the toy from Celestia, “where should I put it then?”
Celestia giggled and lifted her tail and raised her butt all the way and shaked it. “Try the other hole,” she winked.
After pausing to realize what Celestia meant, Luna, blushed and responded “Oh? Are you sure?”
“Positive,” the sun princess assured her, gesturing with her bottom up and down.
Luna turned on her side to face Celestia, beginning to push the other shaft into Celestia’s anus. Her sister winged slightly as she pressed the length deeper in, while continuing to slip the one below it in out. Soon she was plowing both holes and vibrating the toys within hard.
“Nnnh give me all you got,” Celestia taunted her “do your worst.”
Luna’s gave a look of surprise which quickly grew into a devious grin as she started to push harder like an errant locomotive. Slamming the shafts into Celestia while fondling her clitoris, sending the sun princess into varied gasps and whines of pleasure as her fluid dripped onto the bed. She made the toys vibrate harder while sliding them in and out of each, sometimes together at once.
It secretly pleased Luna to have this kind of control over her sister; she smiled wryly while resting her head on a hoof. With her other hoof she started touching herself, rubbing her pussy while watching her sister being penetrated so rough with the shafts by her magic. Soon, all the thrusting and vibrations sent her sister into a fit of moaning.
“Coming so soon?” Luna asked teasingly with a giggle as she leaned.
“Ahhh- ahh ah,” Celestia cried in ecstasy. “Mmm, well done,” she muttered in the afterglow as the shafts ceased.
“Shall we try it again?” offered Luna with giggle “This time you could try licking my marehood while I, you know?”
“How bold of you to ask such,” Celestia spoke with a chuckle. “Very well.”
Luna got into position in front of her sister sitting upright on a pillow with her sister facing her soaking wet sex. As soon as Celestia began to lick, Luna’s horn lit up started working the hard shafts still inside, sliding them in hard, often getting a huff out of Celestia. She rested a hoof on the back of her sister’s head and pushed her snout further into her pussy.
Celestia put her forehooves on Luna’s thighs as she worked her tongue, sliding around and lapping at the walls and crevices with increasing vigor, often suckling her clit and wrapping her tongue around, sliding it around. Sometimes, from the sheer force of Luna’s thrusts into her holes, she had to stop to moan hard into her sister’s crotch.
Luna watched at her sister started lapping her vagina up like a thirsty kitten. Her eyes drifted up to her sister’s horn and she started touching it. “Ahh-ah, I wonder, have you ever put this inside mmph, a mare?” Luna asked.
Celestia pulled away “Ahhh, I think there was one a long time ago, AHA! I-I can’t really remember,” she tried to recall.
“Well maybe we could try it?” Luna said giggling.
Celestia agreed, tilting her head down then slid her horn inside, it’s swirling grooves driving Luna wild.
“Ohh, ohhhh, fuck yes! Just like that!” Luna exclaimed as her sister’s horn went inside.
Celestia pushed the horn in deeper into Luna’s wet insides as both moaned in pleasure. Her horn made a wet slap each time she drove her horn in and covering her forehead in her own sister’s juices.
Luna was nearly overwhelmed by her sister horn, but wouldn’t cease in her relentless pounding of Celestia’s rear, slamming the lengths in one after the other and vibrating hard. The two mares together made symphony of moans as both sent the other into a fit of orgasm, wailing in ecstasy as their unusual sex act reached its tipping point.
The two regal siblings rested, catching their breath after an already long night of debaucherous sex. Holding one other in their hooves as Luna licked her juices clean from Celestia’s face, lapping it up as her sister giggled softly. After recovering, Luna lifted her head up. Curious of what else her sister might have brought with her, she drifted the box over.
“Let’s see what else you have here, oh…” said Luna as her eyes widened at the sight of the big double ended purple dildo before her, “my, this looks quite fun, never seen anything like this before.”
“Mmm, I wasn’t sure if you’d be ready for that sort of thing,” spoke Celestia fatigued.
“Well,” said Luna with a devious grin on her face. “I am now.”
Celestia smiled back, and very soon both her and Luna were lying on their backs, their legs spread and interlocked with the toy between them wedged firmly in their pussies. They bucked their hips into the other’s, trying to time it in unison, sending shockwaves of pleasures throughout their bodies as the shared shaft pushed deep into them.
“Annrgh harder this time Luna,” said Celestia right before they slammed their waists together. “Ohhh yes, just like, thaaaaat.”
“Ohhh, it feels so good, agh,” exclaimed Luna in a moaning wail “I love you sister! Unnnf.”
“I-I love you too sis,” said an ecstatic Celestia as she withdrew her hips before pounding against Luna again.
Their wings flung open as the two climaxed, flapping them and knocking over objects in a gust of wind. The two spent nearly an hour with smashing the big violet length into each other over and over, thrashing their hips wildly and moaning loudly from their multiple orgasms together. All the sound from their sex noises and crashing echoed down the hall away and was bound to catch somepony’s attention eventually.
The doors flung open and several guards bursted through.
“What’s going on here!?” one guard demanded to know.
By the time they got there the sisters were standing fully dressed in their appropriate apparel, off the bed, the room was clean, and with their toys hidden away. They looked at the castle guards and laughed.
“Oh nothing Cobalt, was just doing a bit of catching up with my sister,” said a facetious Celestia.
“It sounded like Princess Luna was being attacked!” said Cobalt confused.
“What is that smell?” said one guard sniffing the air.
“Celestia just said something really surprising, scared me a bit,” Luna played it off.
Celestia nodded and continued quickly “Yes, and it’s a new perfume I’m trying, do you like it?”
The guards looked puzzled at each other, then to their princesses. “Okaaay?” said one awkwardly, “I guess,” said the one asking about the smell.
“Well, we had better let Luna be,” Celestia expanded her wings hurrying the guards out as she left “she has a busy night, and I should be in bed.”
“Isn’t it almost morning?” asked an inquisitive guard as the sun princess brushed them out beneath her wings.
“Don’t worry about,” Celestia said. Before closing the doors behind them she looked to her sister “See you tomorrow Luna,” she said suggestively, giving her a wink and a smile, to which Luna reciprocated as the doors shut.
