Eternally Loved
Eternally Loved
By: NeonEclipse
Celestia made her way down towards her sister's room as the many clocks in the castle started chirping their midnight call. She didn't normally stay up to this hour, but it was important that she see her sister this night. She kept her pace even and held her head high as she walked, but her heart was heavy with doubt and fear for what would come once the night was over.
When she rounded the last corner, she found the two guards that were normally posted outside her sister's room, were now eyeing the doors warily. As she approached, one of them caught sight of her and, after a quick jab to his partner, they both quickly took more sentry-like stances.
“Your majesty!” They stated simultaneously, throwing a hoof up in salute.
She took a look at the large blue twin doors that concealed Luna's bedroom, silently wondering what made them drop their guard. “Is my sister still asleep?”
They glanced at each other, then one said, “I believe so your majesty.”
She nodded in understanding, having figured that Luna might have gone back to sleep after raising the moon. “I wish to talk with my sister, so I will wait for her to wake.” She said to the two guards, giving them a benevolent smile. “You may both turn in for the night.”
They both looked at the door, then back to her, and nodded. “Yes, your majesty.”
They took off down the hall, and, as they turned the corner, Celestia approached the doors. She hesitated somewhat before them, the rational part of her mind begging her to go back to bed and forget this, but her will held out. This was important, she knew, and had to be done.
With some skillful use of magic, she opened one of the azure doors without making a sound, and entered the dark room. After closing the door behind her, the light from the hall faded, and now only the white light of the moon illuminated the room through the balcony window. The soft glow coated the room’s surfaces in a silver glaze and allowed her to see where she was walking for the most part. It also let her see the small bulge that was her sleeping sister, in the large bed at the other end of the room.
It had been a few months since her sister had finally returned to her. Luna went through a lot, recovering from her time in banishment. She would often sleep through much of the day, and even her own night sometimes, still recovering from the effects of the Elements. They had saved Luna, cleansing her of the evil inside her, but leaving her in a weakened state. She didn't like to talk about what she’d gone through over the last thousand years, so Celestia avoided the subject to avoid causing her any more discomfort.
After all, it was her fault it happened.
“Sister...”
For a second she thought that Luna had woken up, but, as she entered further into the room, found her to still be asleep. She could now see the blue alicorn tossing in her bed, the covers messily scattered and tangled around her, and hear small whimpering coming from the sheets.
“Why won't you look at us?”
Now that she was close enough to see clearly in the low light of the room, she could see tears on Luna's cheeks, reflecting in the silvery light.
“We're sorry. So sorry...”
Celestia’s throat tightened as she heard her sister crying out for her in her sleep. She was suppose to protect her sister from these things, and it broke her heart to know that she was the cause of them.
“Please... please don't leave. Its so cold... so lonely...”
Celestia couldn't stand to see her sister in such a state, and came up to the bed, gently scooping her restless form up in her hooves.
“No Luna. I won't leave you. Never again. I'll always be here for you.”
Luna's eyes slowly opened from the sudden movement, both glazed with tears. She looked somewhat surprised to see her sister but still gladly threw herself at the white alicorn, seeking her embrace.
“Sister!” The dark mare cried as she latched onto the white alicorn beside her, burying her face in the comforting warmth. Celestia unfurled one of her large white wings and wrapped it around the blue alicorn like a blanket. Even though she had just woken up from her rough sleep, she already had tears pouring from her eyes.
“Shh... Shh...it’s okay.” Celestia cooed softly as she ran a hoof through her sister's mane, working through it in long, slow strokes. “I'm here.”
Each stroke brought out another hiccup or sob from the smaller pony as she held her tightly against her body, wrapping a white wing around her shaking form. Luna wept into her sister's white fur, matting it with tears. If Celestia found it to be uncomfortable, she didn't show it.
After a while under her older sister's ministrations, Luna began to get her breathing under control, and stop her tears somewhat. Even her violent shaking had slowed down and disappeared in the soothing hold of the white alicorn.
“It was only a dream. You're not there anymore, you’re home now.”
“We know, sister. But... it... it hurts so much sometimes.” Another sob worked its way through her, hooves still tight around her sister's neck. “When Nightmare Moon lost, she vanished into the recesses of our mind and hid herself until the end. She gave us back control of our body... ”
“We were conscious for every moment of our imprisonment! For a thousand years there was nopony! We were alone!” More tears filled the midnight alicorn's eyes as her empty memories of the thousand year void rushed back to her. Celestia just held her tighter in an attempt at consolation.
“I'm sorry Luna. I know it was hard, going through that, but I promise I will make it up to you...”
She lowered her muzzle down to nuzzle against her sister's lovingly and drew back a bit so that she could look into her eyes, only a few inches between them. “You never have to feel lonely again Luna...” She finished, closing the last of the space between them and capturing her sister's lips in a tender kiss.
Luna's body went rigid as her sister pressed her lips against hers. Thoughts becoming like puddy as every nerve in her twitched at the contact. Part of her was disgusted and instantly repulsed by the action, knowing that it was wrong on a fundamental level. But a deeper part of her was surprised by how soft Celestia’s lips felt pressed against hers. She was so shocked by the sudden kiss that she panicked and pushed her sister away, breaking contact.
Celestia didn't put up any resistance and let Luna push her away, also shocked by her actions. “I...” She began, trying to explain, but, at seeing the shocked and slightly scared look on her sister's face, she couldn't finish. She hadn't meant to frighten her. She just wanted to show Luna that she cared. And because of an unthinking impulse, she destroyed her one chance to properly explain herself. She turned away, unable to look her in the eyes any longer.
Luna was still spinning from what had just happened. She brought a hoof to her lips, still feeling her sister's pressed against them, velvety and warm.
“Why... Why did you kiss us...?” she asked quietly, confused and conflicted.
“Because I love you...” The reply hinting at nothing about the emotional status of the white alicorn before her. “More than one should love their sister.”
Luna 's cheeks reddened. Never before had she caught any hints of incestuous feelings towards her, so why now, all of a sudden? What had changed? “And how long have you... loved us like this?”
“I have loved you this way for a long time Luna.” She admitted, a touch of sadness in her voice. “I loved you like this long before our seperation, even when we were still fillies, I’ve always thought of you this way.”
“W-what? That can't be...”
“It’s true.” Celestia said, finally turned to face her. No longer able to hold herself together, both of her wings sagged towards the floor, and her head hung low as tears fell from her cheeks to the padded carpet below. "I love you Luna."
She’d dealt with this by herself for most of her life, never talking to others or being able to let out all the frustration and sadness, and it had taken its toll on her. But now she could finally let it out, and with it, all the pent up agony from countless years of repression.
“But you would barely even show yourself around us! If you cared about us as much as you say, then why? Why did you avoid us?” Luna said, tears once again welling in her eyes. “You never cared before... so why now...?”
“I have always cared for you." Celestia said as though it were a terrible lie to say otherwise. "I ignored you because I couldn't deal with my feelings around you. I didn't want to let you find out and ruin what we already had together.” She began to shake, much like her sister had not long ago, as she cried out, “But in doing so I left you alone when you needed me most! I should have been there for you all those years ago. Before you returned, I wished every day that I would have done things differently.”
She clenched her teeth together in frustration of her past mistakes, more tears streaming down her face. “So I decided that I wouldn't make the same mistake twice. Now that I have another chance, I would rather let you know, and have you find me disgusting, than lose you for another thousand years!”
As she finished, Luna could only stare at the alicorn before her, utterly speechless. It was a rare occurrence to see her older sister crying openly in front of another, but seeing Celestia in such a miserable state made her heart ache.
“You aren't disgusting sister, we're actually flattered that you find us... attractive.” The words caused Celestia to look at her. “But... But we are sisters. We must find others to love, not each other. It’s wrong to have feelings like these.” Luna had hoped that her words would ring true to her sister, but as soon as she said them, more tears formed in the white alicorn’s eyes.
“I’ve tried... I tried so hard. For more than a thousand years I tried to find somepony else to love so that I wouldn't have to bring this on you...” Her mind raced through the past and all the ponies she met. “But everypony I met had a clock inside them. Slowly ticking away every second to their inevitable deaths. I would always be left alone in the end no matter who I chose.”
“But you are still here, even after everypony else has gone, even after a thousand years, you remain.” She smiled fondly at her younger sister, eyes glazed with tears. “You are all I have, Luna. No matter who I try to fall in love or find happiness with, in the end they will all vanish from this world, and I will live my life in endless sorrow. But you are like me, bound to unending life.”
“I love you Luna. I'll love you forever my beloved sister. I won't ask you to return my feelings, but please don't call them wrong when they're my only chance at an eternity of happiness.”
“Is that the only reason? Because our long life?” she whispered, but Celestia just chuckled sadly.
“Didn't I tell you already? You were the first pony I ever loved. Even as foals I was always watching over and protecting you. As we grew older I couldn't help but look at you as a mare, rather than a sister, and I knew that I loved you much more than a sibling should.”
“I waited a thousand years to tell you, and I will wait a million more for you to accept my love. No... I would wait forever for you, Luna. It’s not that you’re the only pony I can love, it’s that you’re the only pony I do love. You will always hold a place in my heart, sister. You mean more to me than any other.”
A long silence followed once Celestia had finished speaking, and, as it wore on, she began to despair that her sister thought ill of her words. She anticipated Luna would likely reject her. It would hurt, it would hurt a lot, but she could handle it on her own time and hide the sorrow that would follow. She just wanted to have this all be over already instead of dragging it out.
“Do... Do you really mean that?” Came a quiet whisper from the blue alicorn.
Celestia's eyes widened, and she looked up to find her sister looking away, blushing heavily.
“W- We... we never really loved another before...” She said, bringing her eyes to her sister’s, and then quickly away. “But... we do love you, sister. Maybe not to the same degree, but...” She brought her voice so low that Celestia almost missed the last few words. “We would be willing to try...”
Celestia began to tear up, new hope rising in her. “You mean...”
Luna nodded in response, but her eyes remained averted.
Celestia's mouth hung open in disbelief. Luna was willing to give her a chance. Even with how wrong it was for them to do this, she would still give her feelings a try. She quickly drew her sister close and hugged her tightly, feeling happier than she had ever been. “I promise you won't regret it. I'll never let you feel lonely again. I will always love you my sweet, sweet sister.”
Luna remained still as her sister held her. It didn't feel real, almost like she was still dreaming. She wouldn't be surprised if she woke up any minute now.
“Others... wouldn't find this type of relationship between us very agreeable. Many of our subjects would probably oppose it, and cause trouble down the road.” She said, giving a last line of defense against changing her mind.
“I couldn't care less what others think of our relationship. The only pony's feelings that matter to me on this are yours. I will give you my love for as long as you're willing to accept it.”
Luna could feel her heart beating wildly inside her as her head became muddled with incoherent thoughts. She knew what she was about to do was wrong in a basic sense, but her sister was right. For those that had to live their whole lives watching everyone around them wither and die, why not take a chance at having a love that could last?
Eventually she felt her sister loosen her grip and pulled away, looking at her with a loving smile.
“Could you...” She began feeling nervous under her sister’s intense gaze. “Could you kiss us again...?” She asked, rubbing her hooves together nervously and blushing furiously through her dark coat.
Without a word, Celestia gently lifted her face with a hoof and pressed their lips together much like before, but this time, Luna slowly began to return it. She felt a tear of happiness roll down her cheek as her love that had gone unknown for so long was returned.
The blue alicorn was a little startled when she felt her sister's soft tongue work its way into her mouth and start flicking hers playfully. After a while, she dared to try and return the movement, and was quickly swept up in a passionate dance with her sister's wet muscle.
It wasn't a lie when Luna said that she didn't love her sister as a mare. In the past, though, as a filly, she used to wonder what it would be like to love her sister this way. It was only a passing phase, and it did fade away with time, but now, with her sister kissing her like this, she could feel the old desires that had taken root begin to come alive again. The want to love and be loved by her big sister in every way possible.
They stayed tightly locked together as Celestia started to move her hooves over her sister's neck and wings, slowly trailing over her barrel, caressing each part of Luna’s body gently. She broke away to start planting little kisses over her sister's face and neck as the blue alicorn panted from her lack of breath.
Luna groaned as Celestia nibbled on one of her ears, a normally playful gesture now given a more intimate meaning. She could feel heat beginning to build up between her legs and started to rub them together subconsciously.
Celestia noticed her sister's subtle shifting of her legs and moved so that she was laying parallel beside the dark mare, but inverted, her head now facing the midnight blue flank. She started stroking her sister's rear, admiring it for its firm build and soft curves.
“You know, you really do have a beautiful flank, sister.”
“O-Our flank?!” She squeaked out.
“I have to be honest. I had some rather impure thoughts of it when I was walking behind you as we retire to our rooms from dinner last night. Your tail barely covering your filly parts and your flank swaying from side to side as you walked.” She was slowly caressing Luna’s back-end with her hooves, drawing circles around the cutie mark, but leaving it untouched.
Luna blushed heavily as, what used to be a innocent memory, became something not so innocent.
“You really should control your ethereal tail better, I swear sometimes you would keep it floating high on purpose just to tease me.”
“W-we never intended t- ah!”
Luna couldn't finish her sentence as Celestia licked her cutie mark, drawing out gasp from her which turned into a needful groan. Her sister carefully worked over her haunches, causing a tremendous heat to well up inside her. But right as her heat had hit an unbearable level, she felt her sister's hooves move away from her as she stood up and left the bed.
“Well I guess I should be going sister. You must still be tired and I wouldn't want to keep you from your sleep any longer.”
Celestia turned to go, hiding her smirk at the expression her sister made when she said that. She didn't make it halfway to the door before her sister called out.
“Wait! Don't just leave us like this!”
The white alicorn turned around and gave an innocent look. “Like what Luna?” She knew what she meant of course, how could she not? She could smell it in the air, the heavy scent of her sister's arousal, she just couldn't resist the urge to tease her a little.
“It aches sister, please...” Luna's ears were pinned back and her mouth was slightly open, hot pants coming from her.
Celestia approached her sister once more and started rubbing her hooves over her in various places. Luna grunted and whined as her sister deliberately avoided her problem area. Celestia could see the pleading look in her sister's eyes, begging her to help.
“Where does it hurt Luna? I need to know so I can sooth it and make it feel better.” She whispered sweetly.
Luna continued whimpering in distress, choosing not to talk, but her tail twitched as if flagging attention to the burning occurring in her loins.
“Oh, I see...”
Celestia moved to her sister's haunches exceptionally slowly, much to Luna's misery, and carefully ducked under the dark, sparkling tail; she could see now that her lips were badly irritated and inflamed. It surprised her that she had caused such a large buildup of heat, she had only meant to leave her slightly bothered.
“Oh my... I’m sorry Luna, I seem to have neglected you.” She uttered softly, giving her flank gentle strokes with a hoof. “Do not worry though, your big sister will make it feel better.”
She knew that she would be taking her sister's purity, but she would also be giving her something of equal value in return; her love. Without a second thought she buried herself between the dark blue cheeks, flicking her tongue over her sister's pink marehood, and tasting her for the first time. Luna's tail lifted slightly at the sensation, and she let out a little scream of delight as her sister licked her aching spot. Celestia quickly found that loved the taste and began to lick it as if she were eating a sweet dessert.
Luna couldn't believe what her sister was saying, or, for that matter, what she was doing. Even though she’d missed a thousand years she still knew these incestuous desires were wrong. But she couldn't deny how good it felt. Her body shook with each delicate lick over her pink petals, and her cries rose in pitch. No other had ever touched her in these ways, for she had been pure, and had never made love to another. But now her own sister was touching her in her most intimate place and gently loving her. Suddenly, it didn't matter anymore that they were sisters, that what they were doing was wrong, all that mattered now was the love she was receiving from her sister.
Celestia withdrew her muzzle from her sister's flank, licking her lips as she stood up. She had a smile plastered on her face along with a good amount of sticky liquid.
“You taste wonderful Luna. Sweet, like honey.”
Luna's face heated up from such a brazen statement from her normally serious sister. Just as she dared to peek back, a bright flash illuminated the room with golden light. But it only lasted a second before the light vanished and the room fell back to darkness.
“Sister, what was...” Luna began, but was interrupted as Celestia caught her in another kiss; the fact that she could taste herself on her sister's lips arousing her even further.
“Just giving us some privacy dear sister.” Now that no one would hear them she had no reason to hold back. She wanted to make her sister cry out more, to feel even better. “Why don't you lay down on your back Luna, that way I can better 'help' you with this problem.”
Luna quickly turned over, too bothered now to care what position she was in. But, as she settled back down and looked into her sister's eyes, she could now clearly see all of the heat and desire in them. She couldn't bring herself to look away as Celestia’s gaze seemed to hold her in place.
“There, now we can see each other.”
With her sister splayed out in front of her like that, it took all the restraint Celestia had to not pounce on her right there. She wanted this to be something special between them, something that Luna would always remember.
Gently setting her hooves down over her sister's legs, she positioned herself between them. She looked up at her sister lovingly before digging back into the sweet marehood. Luna resumed her cries of passion as Celestia treated her aching sex.
“Does it feel good Luna?” Celestia said, keeping their eyes locked.
Luna could only nod her head as she held a hoof to her mouth, trying to hold in her moans.
“Where does it feel better?” Still Celestia's eyes stayed glued to her sister's, but Luna refrained from letting out more than the occasional gasp or grunt of pleasure.
“I can't help unless you tell me...” she cooed, giving errant licks across her sister's sex. She delighted in hearing Luna’s loud moans, and as much as she enjoyed teasing her, she also wanted to hear her sister call out to her.
“There! It feels good there!” Luna cried out, unable to contain her voice as Celestia brushed her tongue over the small bud at the top of her marehood.
Celestia smiled as she licked, giving the little bit a long suckle, rewarding her for letting her voice out before returning to wide licks across her entrance. Luna gasped and moaned as her sister sucked on her sensitive bud, pleasure, like electricity, coursing through her body.
Luna could feel a pressure beginning to build up inside her from such direct stimulation. She could feel it coming in waves, slowly pushing her closer and closer to the edge.
“W-we're starting to feel s-strange sister!”
Celestia just smiled at the innocent statement and started licking more eagerly, encouraging her sister to release for the first time. Each quick pant and wordless groan from her sister's mouth was music to her ears.
“Its okay, your sister is here for you. Just let it out...”
Luna's hips bucked, and her whole body tensed as she reached the top, then cried out as she fell.
Her hips jerked so violently that Celestia had a hard time keeping close. The first spurt of liquid caught her by surprise as it spritzed onto her muzzle, though she was quick to recompose herself and lick away, catching the rest of her sister's release in her maw.
“That's it Luna.” She murmured in between licks. “Let it all out.”
Luna continued to cry out as the constant licking, along with her sister's naughty words, drove her first ever release even further, drawing it out even as her vision went white from pleasure she had never before experienced. Each spurt of liquid she let out being instantly taken in by a quick flick of the white alicorn’s tongue.
Her hips still automatically bucked into her sister's mouth, even after her release had ended. It wasn't until Celestia pulled away that they finally settled down.
Celestia took great joy in the fact that she was the one to bring her sister to her first orgasm. She looked up at Luna, wanting to see the satisfied look on her face, but instead she saw her sister biting her lower lip and whimpering.
“Please sister. It’s still so hot...”
Luna reflexively tried to rub her haunches together again even as Celestia was still positioned between her legs. The heat slowly coming back in full force and igniting a burning desire inside her.
Celestia frowned, thinking that she had failed to properly satisfy her. “I'm sorry sister. Have I left you unsatisfied?”
She shook her head. “No. That was amazing. It’s just...” She looked away in embarrassment. “Our yearly season started last week, so we are very aroused right now.”
“You mean... you're in estrus?”
Luna blushed and nodded.
Celestia considered for a moment, what would be the best way to please her sister while she was in heat. Her eyes widened as a particular thought struck her, and she asked hesitantly, “Luna... I would like to try something with you... if you would like. I think it will be better suited to help your heat.”
Luna contemplated what it might be that her sister had in mind, but she had already come this far and she was in an incredible heat at the moment.
“We are alright with anything you have in mind sister.”
Celestia gave a little nod and got off the bed, leaving her sister spread out on it, watching her intently as she began to channel magic into a spell.
“I never really had a reason to use it, but I think now is a good time.”
Luna watched her sister's horn ignite with magic and flash brightly for a second. Temporarily blinded by the bright light, it took her a minute to finally notice exactly what it had done. But as her eyes wandered over her sister's form, she could now see something sticking out underneath her.
Celestia had a generous length protruding from between her legs. It was white, like her coat, for most of it, with a slightly pinker tip that flared out at the end. There was also a pair of two round white orbs hanging from the base of the long stallionhood. Luna's jaw dropped.
“H-how is something like this even possible?”
“Over the years that you were gone, a great deal of new spells have been discovered by unicorns. One of which was a way to manipulate a pony’s genitalia temporarily. And not just in looks either, it’s actually commonly used among mare partners that want to have foals.” She ended, giving her underside a quick look to make sure the spell had been successful.
“You mean this could...”
Celestia looked up and nodded, brushing one of her legs against another.
Luna could feel something in her mind break at the thought. She could have her own sister's foal growing inside her with this. Just the thought alone was enough to make her nether lips secrete large amounts of mare cum. She was ashamed of herself for getting so worked up over this, but, in her defense, she wasn't exactly in the best state of mind right then. Where she hesitated, though, was at the sheer size of the her sister's new length. She didn't even know if it would fit inside her.
Celestia mistook her hesitance for fear and added in. “Not that I would ever force that upon you. I will only do what you feel comfortable with.”
“Its okay, sister. I wouldn't have come this far if I did not trust you completely. Its just... so... large...”
“O-oh?” She said, blushing as the comment caught her off guard. Luna just nodded dumbly.
The dark alicorn got up and looked towards her, unsure of what to do now. She didn't have any experience with anything like this, and assumed that her sister didn't either. “S-Should w-we...” She stuttered, turning to point her back-end at Celestia.
“You can stay lying on your back, Luna, just come closer to the edge.” The white alicorn said, patting a hoof on the soft mattress. Luna moved as instructed with a slightly doubtful expression. She knew something of what position a mare was supposed to be in for a stallion to mount. Though, as she laid back down and Celestia positioned herself over her, she was surprised to find that they fit perfectly together, pure white fur against her dark blue coat, a hoof on either side of her.
The bed was high, and a perfect distance for her while standing on the ground with her back legs. It was almost too perfect as Celestia lined up, her impressive length resting right on top of her stomach, just above her entrance. Not only that, but something about being able to see her sister while they would be doing this made her feel so much better about the situation. She could clearly see the lust in her magenta eyes as they looked to each other.
Celestia carefully drew back, bringing the tip of her member against her sister's entrance. She took a look at Luna, waiting for her acquiescence. She dearly wanted to finally come together with her sister, but also wanted her to feel completely safe and in control while in her hooves.
With a quick nod, Luna gave her the signal to go ahead, clenching her eyes shut as she waited for her sister to begin. She could feel everything as Celestia slowly inched herself forward, her lips parting around the tip as the white alicorn pressed into her, stretching her further with each inch. She cried out as Celestia pushed through her maidenhead, tears from the sharp pain it caused welling in her eyes.
Luna struggled to contain her sister’s girth as her tunnel was filled for the first time. She couldn't believe how much more satisfying this was than her sister's earlier ministrations. Although it was painful, it also served to satisfy a deeper need inside of her, right at the source of her heat. Luna groaned loudly as she was stretched even further around her sister, who continued drawing ever closer to the center, where the ache was strongest.
Inch after inch filled her until she became too tight to press in any further, and the white alicorn had to come to a stop. She struggled around the thick length inside her, her walls contracting rapidly as it stayed rooted deep within. She had thought that it had looked large before, but it felt even bigger now that it was inside her, filling her completely.
Celestia still had some length left outside, but she didn't want to hurt her sister by forcing her to quickly accommodate more. Seeing the tears that threatened to fall from her sister’s eyes, she nuzzled softly against Luna's cheek and took her into a kiss. It served to calm her down a little as Celestia felt the blue alicorn walls begin to loosen around her.
Luna could feel the length pulsing inside her at a steady rate, soothing her with its gentle rhythm. After a bit she realized that it was, in fact, her sister's heartbeat she was feeling. She could actually feel her sister's heartbeat through their connection. Her body relaxed as they kissed, her own beat unconsciously falling into sync with her sister's as they lay there, connected.
Soon though, Luna slowly started to rock her hips up against her sister, ready to continue now that the pain had passed. Celestia took that as her sign to start moving, and pulled out slightly, only to give a triumphant thrust back in, reaching even further depths.
Luna moaned as Celestia thrust into her, managing to delve deeper inside her. The feeling of her sister pulling out, leaving behind an aching emptiness, and then the delicious stab of pleasure when she came back in was enough to make her want to cry.
“It feels so good sister! Please don't stop!” she begged.
Celestia wouldn't dream of it. She repeated the process again and again, each time gaining more depth. The cute moans coming from Luna making her redouble her efforts with each thrust, wanting to bring her sister’s pleasure to further heights. She kept up a steady pace until she felt the last of her stallionhood enter, the tip pushing up against something deep inside her sister's marehood.
When her sister tapped against her deepest barrier, the scream that left Luna would have awoken half the castle, since part of her royal Canterlot voice was mixed into it. Her body spasmed wildly as each thrust that followed brought the tip to brush across her cervix, making her squeal out in pleasure.
Between her sister's vocal sounds of approval and her walls squeezing her tightly, Celestia could feel her climax closing in on her. She lowered her body and pressed into her sister, bringing herself close enough to whisper into her ear.
“Luna, I'm close.” She purred hotly. “What do you want me to do?”
Luna's thoughts raced as she contemplated what her sister had said. If she let Celestia fill her then there would be no hiding this from the public. There would most likely be consequences for this, and she had just finally managed to start connecting with the populace. They would have to deal with this for many years until they would let them be.
She looked up into her sister's eyes and immediately knew what she wanted.
“Inside! Finish inside us!”
It was risky.
It was stupid.
But it was what she wanted.
And when she looked into Celestia's eyes, she could see all of the love held in them. She knew that her sister would be there with her for every moment, that she would be there for her forever. And she knew that it was worth it, for an eternity of love from her sister, it was more than worth it.
She was a little frightened by the thought of having a foal, but it was overwhelmed by a powerful urge to have this length inside her and be filled with its gift. That, and a cardinal desire deep inside her that wished nothing more than to bear her sister's foal.
“We will have your foal, sister!”
That was more than enough of an answer for Celestia, who started picking up her pace, no longer holding back. Each stroke made her groan as she hit up against her sister's cervix before pulling back. Luna melted each time Celestia bumped against the entrance to her womb, and she couldn't keep from screaming in delight as her insides quivered in pleasure around her sister's girth.
Celestia finally reached the point of no return, her head flaring while still deep within her sister's warm folds. She was panting heavily at this point, and her thrusts were losing accuracy. Her pair of magically created testes drew up against her as they prepared their load. Her wings shot out to their fully extended form from the intense feeling going trough her.
“Yes Luna, it’s coming! Lets make a foal together!” She cried out, her ears laid back against her head.
Luna felt her passage stretch as her sister flared inside her, she knew what was coming, and quickly wrapped her hooves around her sister's back. Celestia gave a final thrust into the dark alicorn and paused as she clenched her body close, their hooves wrapped firmly around each other. She groaned sensually as she felt herself twitching violently.
Luna's entire body jerked as she felt the first thick spurt hit against her deepest spot, right up against her cervix, coating it in the creamy liquid. The feeling and the thought of her insides being painted with her sister's warm, incestuous seed caused her to reach her own peak, and begin contracting around her length.
She arched her back and cried out as Celestia pulled back a little and pushed even further into her in a desperate attempt to get even deeper into Luna's quivering sex. Her back legs dug into the carpet as she tried to push forward into her sister while keeping her locked in place with her forelegs. Luna's body could only respond by buckling back against her sister, also wanting her to gain more depth.
Their mutual wish was granted as Celestia sank a little further into her sister's warm walls, grinding against Luna's cervix until it parted slightly. The white alicorn groaned as her little sister's walls rippled around her, naturally working to align the head with the small opening.
Luna's eyes widened as the entrance to her womb opened a little, and the second volley of her sister's hot sperm shot directly into her uterus, coating it in the alicorn's gooey, virile seed. She couldn't hold back a scream of satisfaction as an emptiness inside her, that she hadn't known of until now, was thoroughly filled.
“Oh... oh sister...!”
Luna shook as each thick shot filled her, and more of her sister's hot sperm was forced into her uterus. She could feel each pulse and twitch of the white shaft as thick cream was deposited within her depths in rapid, powerful bursts, filling her fertile womb with her sister's essence. Her hips rotated desperately as she tried her best to work out as much of of the seemingly endless spurts as she could, wanting it all inside her.
Eventually though, Celestia's spurts began to lose their volume, and, after giving her sister the last of her warm spunk, she came to a stop, still deep inside of Luna. Letting out a delighted sigh, she carefully retracted from her sister to make sure that her uterus closed back up before any of her seed could leak out. Once she had finally cleared her sister and fully exited, only a small trickle of white could be seen dripping from the now satisfied sex, showing that the rest remained deep in the dark alicorn.
Luna could feel the gentle heat radiating from the large quantity of potent alicorn seed pooled deep inside her uterus. One of her hooves snaked its way down her stomach and rested right where her womb was located. She felt stuffed inside, full from her sister's hot milk as it worked hard to put out the raging heat that had built up inside her. She began to purr softly at the feeling and smiled when Celestia nuzzled her hoof out of the way to lick at the fur there, rubbing it tenderly with her muzzle.
“We're so full sister... You put so much inside us...”
She could almost feel the innumerable sperm cells working their way to her ovaries. There was so much warm spunk packed inside her that there was no doubt in her mind that her eggs would be fertilized, and she, impregnated by her sister's seed. She found that she did not regret it, coming together like this with Celestia. She felt safe and calm in the protective presence of her sister, and knew that everything would be alright. But still... she couldn't help but worry at what was to come.
Celestia lay down next to her and began to lovingly stroke the soft fur of her sister's stomach. She looked up at the blue alicorn and took notice of the lines of worry etched into her sister's face.
“Are you scared?” She asked, worried that she had gone too far.
Luna slowly shook her head. “No. It's just...” She looked down at her belly. Celestia knew what she meant, and nuzzled her affectionately.
“You are beautiful Luna, so I am positive that our foal will also be beautiful.”
Luna blushed at the comment. “We're sure they will have your beauty as well sister.”
Celestia turned her head to look curiously at her. “They?”
“We just have a feeling...” she said, curling around the white alicorn.
Celestia rested her head against one of her sister's soft wings, her ethereal hair acting almost as a blanket, covering the lower half of the dark alicorn. Luna just draped a hoof over her sister and laid her head down over the sun cutie mark on her flank. Both content and basking in the afterglow of their embrace.
“I love you Luna. I'll always love you. For all eternity.”
Luna rubbed her head over her sister's cutie mark, trying to snuggle closer.
“We know. We love you too sister.”
Little did they know that the fruit of their love had, in fact, taken the form of two new lives, now growing inside the midnight mare's body. The product of both the sun and the moon.
Both light and dark.
Day and night.
Dawn and Dusk
