It's never healthy to repress hidden feelings. Luna is about to experience the effects of doing so firsthand. The trouble starts when those feelings... are about your sister.

A long, drawn-out sigh escaped her lips, and she flopped onto her bed. “What are these feelings?” she wondered aloud. “Why do I feel this way about her?”

Deep inside the heart of Princess Luna, there roils a cauldron of emotions, boiling and heaving, hissing and spitting. The fire that fuels these emotions is also a Princess, one who is very close to Luna. She is strong, courageous, and Luna couldn't bear to live her life without her...

Chapter 1

Luna lay awake in her bed, unable to sleep. She tossed and turned, the covers mangling about her hooves and wrapping her up in their linen embrace. The princess of the night kicked out in an attempt to free herself, but to no avail.

She sighed, and struggled against the cocoon of blankets in which she was wrapped. “Oh, for goodness sake!” She gave another kick, but only succeeded in wrapping herself tighter in her blankets.

A long, drawn-out sigh escaped her lips, and she flopped onto her bed. “What are these feelings?” she wondered aloud. “Why do I feel this way about her?”

She shook her head, and pushed the invading thoughts to the back of her mind, before collapsing onto the bed, wrapped in her linen casket, with a heavy sigh.

“She wouldn’t understand anyway.”

The morning came, and Luna rose from her tangle of blankets, her mane as tangled as the blankets in which she was wrapped, and her eyes red and bloodshot from lack of sleep. She struggled to free herself, having surprisingly more success than last night, and heaved herself onto the edge of the bed.

She struggled onto her hooves, and tried to walk, but her exhausted legs gave out almost immediately, and she collapsed back onto the mattress with a soft thump.

She sighed, and forced herself to her hooves once more, trotting shakily out of her bedroom and into the dining room, where she found her sister waiting patiently for her.

“Dear, Luna, what is the matter? You’re usually the first one up for breakfast, and somehow, I am the one to best you. “What is on your mind, sister?”

Luna shook her head and trotted into the dining room, sliding her chair out and flopping into it tiredly. “It is nothing.” Luna assured her sister, but her tired eyes and slumped posture said otherwise to the ivory-coated mare.

“Rubbish. Luna, you have obviously not slept well, and as such, I insist that you tell me what is the matter. I want to help you.”

The ebony-coated princess glanced at her sister with her reddened eyes, and sighed. “It is nothing, sister. Now please, just leave me alone.”
Celestia sighed and returned to her meal, casting a worried glance over at Luna, who slumped in her chair, poking at a soggy bowl of cereal with her spoon.

After watching her sister poke her cereal with her spoon for the millionth time, Celestia decided that she had had enough. She got up from her seat, and whisked Luna’s bowl out from under her nose. “That is it.” she snapped. “I have had enough of this nonsense.”

Luna glanced up at her sister, an annoyed expression on her face. “What?” she sighed. “I told you, nothing’s wrong.”

Celestia shook her head. “That is rubbish, and you know it. You haven’t said a word since you got up, and I am worried. Your eyes are blood red, and that is not healthy.”

“I told you,” muttered Luna, getting up from her seat, “that nothing is wrong. What is so hard to understand?” The princess of the night stormed out of the room, her silver-shod hooves echoing on the marble floors.

Celestia put up a hoof to stop her, but decided against it. Her sister would grow out of this, she was sure of it.

Luna stormed angrily through the halls, the sound of her hooves booming in the long corridor. “Why does she always do that?” she fumed. “I’m fine. I just…” The princess of the night sighed and slumped against a wall, hiding her head in her hooves.

“I just can’t tell her how I feel…”

She looked up as the heard somepony else approach her in the hall, the tell-tale sign of metal on stone telling her that it was either her sister. or one of the guards. Her suspicions were confirmed when the horned shadow that was thrown onto the wall by the burning sconces flared its wings.

“Luna?”

The night princess sighed and got up, torn between walking towards, or away from her sister.

“Luna?”

She sighed and turned towards the sound of her sister’s voice, walking through the hallway until she could see her around the corner. When the sun princess caught sight of her, she galloped towards her and threw her forelegs around her neck.

Luna returned the hug and sighed, sobbing gently into her sister’s flowing rainbow mane.

“Oh, sister, I’m so sorry. I shouldn’t have stormed out like that.”

Celestia laughed in that musical way of hers, and kissed her cheek. “Do not worry, sister. It is OK.”

Luna looked up at her with tear-filled eyes. “R-really? You’re not mad at me?”

Celestia laughed and stroked her mane. “I could never be mad at you, Luna. It wasn’t your fault. I pushed too hard. But I am worried about you.”

Luna sighed. “I know sister. I’m just not ready to tell yet. You understand, don’t you?”

Celestia nodded and smiled. “I understand, sister. When you’re ready to tell me, just come and find me, OK?” She brushed her hoof against Luna’s cheek and smiled.

The feel of Celestia’s hoof against her cheek made Luna blush, and her nether regions began to burn, throbbing gently. Luna let out a small whimper, but managed to suppress it.

“Sister? What’s the matter?”

“I-it’s nothing sister,” Luna stuttered, the burning in her loins returning. Her back hooves skittered nervously, and she could feel herself getting wetter.

Her heart raced, and she was almost sure that Celestia could hear it. ‘Please, sister,’ she thought desperately. ‘Just leave, or I might not be able to hold back…’

Celestia smiled at her sister, and nodded. “Well, if you’re sure. I shall return to my chambers, and if you need anything, don’t hesitate to call me, OK?”

Luna nodded, and Celestia turned to go. As she reached the corner, she stopped, and looked back at her sister with her kind, amethyst-coloured eyes. “Oh, Luna?”

“Y-yes?”

“Make sure that you don’t get any on the carpet.”

Luna burst through the door to her chamber, and threw herself onto her bed. “Oh, sweet Celestia! What is this feeling? I’m burning up!”
Her hooves shook as she spread her hind legs, and rubbed furiously at her swollen, dripping marehood. Pleasure surged through her, and she let out a passionate moan. “More!”

Her pace increased, and her pussy became wetter and wetter with each furious stroke. “Mmm! I can’t take it anymore!” Her mind went blank with pleasure, and she pushed her hoof into her pussy, desperately wanting more.

Her lust burned brighter, and her womb started to itch. “Oh my…”

She rubbed her clit faster and pushed her hoof deeper inside her, desperately trying to reach the itch that had started in her womb. “More! I need more!”

The night princess stroked her pussy, rubbing it against the wooden posts of her bed in an attempt to soothe her burning loins. “I can’t take this anymore! But what can I do? I can’t just ask her!”

She rubbed her pussy faster, feeling her impending orgasm building up within her. “Oh, sweet Celestia! It’s coming!”

Her pants increased in frequency and her heart raced inside her chest. Rubbing her pussy faster, she felt herself becoming hornier, and the orgasm inside her building until she felt as though she was going to burst.

“I- ahh!” Sweet juices squirted out of Luna’s pussy, drenching the sheets upon which she lay and filling the whole room with the odour of her potent princess sex fluids.

Luna collapsed back onto the bed and her heart thundered in her chest. “Oh my…”

A knock sounded on her door, and the night princess bolted up from her bed, certain that whoever was on the other side of the door could easily smell her pheromones through the walls.

“Y-yes?” she called. “What is it?”

“Sister?” called the pony on the other side of the door.

Luna got shakily to her feet, struggling to stand on her legs, which had turned to jelly after her heated experience. “Yes? What is it Celestia?”

“Can I come in?”

Luna sighed. “Y-yes. You can come in, Sister.”

The door opened, and Celestia trotted into the room, her nostrils flaring as she caught the scent which lingered in the air. A devious smile formed on her lips, and she looked at her sister.

“Oh, Luna…” she said. “What have you been doing in here?”

The night princess blushed. “Whatever do you mean, dear sister?” she asked nervously.

Celestia laughed. “Oh, come off it, sister. I can smell your fluids like a hound.” She trotted across the floor to Luna’s bed, her golden-shod hooves echoing on the stone. The smell intensified the closer she got to Luna’s bed, and her nostrils flared once more.

“Oh? It appears that you forgot to clean up after yourself.”

A deep crimson blush appeared on Luna’s cheeks, and she burned with embarrassment. “Sister! What in Equestria are you saying?”

Celestia chuckled. “Nothing. I merely stated an observation. Perhaps you should have thought twice before letting me in, hmm?” The sun princess took her sister’s chin in her hoof and brought it up to make her sister face her.

“Sister! You’re embarrassing me!”

“Am I?” Celestia smiled and glanced back at her sister, who was blushing furiously.

“Oh, stop!”

“Oh, fine. What, if I may ask, was the… ‘inspiration’ for your little ‘adventure’?”

“Sister!”

“All right. I’ll stop.” Celestia laughed and smiled at her little sister.

“Thank you. Now, is there something you wanted, sister?” asked Luna, her face still burning with embarrassment.

“Yes, actually. You don’t think I came in here just to disturb your… moment, did you?”

“You knew?” asked Luna.

“Of course, sister. I could smell it from outside the door.”

“Oh…”

“Did you enjoy yourself, sister?” asked the ivory coated mare. “I trust that you plan to take care of your… mess?”

“Sister! Of course, I will!”

Celestia laughed and nuzzled Luna’s cheek. “Do not worry, dear sister. I am only teasing.”

“I should hope so! I may be younger than you, but I am still thousands of years old, and as such, am perfectly capable of dealing with my own… mess.”

“I know you are, sister. I would never assume anything less of you.”

Luna sighed and swished her starry tail across her dripping nether regions, wafting the scent of her sex right into Celestia’s face.

The ivory mare fought the urge to moan as the smell hit her; even she, the princess of the sun, couldn’t deny that she was getting turned on.
“Sister…”

Luna smiled mischievously. “Yes? Smell something you like?”

Celestia snapped herself from her stupor and shook her head vehemently, her rainbow coloured, ethereal mane flying about her shoulders, lashing the air like a whip. “No! Nothing!”

The sun princess’s heart thudded in her chest, as Luna pressed herself against her, looking into her sister’s eyes and forming a devious grin on her lips.

“Really? Is that so?”

“Of course! How on earth do you expect me to be attracted to another mare, and to my own sister at that!”

Luna smirked and pressed herself harder against her sister’s chest. As Luna nuzzled her, the sun princess was sure that she could no doubt feel her heart beating like crazy inside her chest.

“Very well, sister. I have no reason to be believe that you are lying.” This, of course was a huge lie; Luna knew exactly what was happening, and she was enjoying teasing her sister with her advances.

The sun princess shuffled uncomfortably against her sister, not because she wasn’t attracted to her, but because she didn’t want her to feel the sexual heat that her body was radiating.

As Luna pressed herself against her sister, Celestia gulped loudly, and her heart thundered in her ears. She wasn’t sure how much longer she could hold back, but she knew she had to.

The feelings that had been welling up inside her threatened to break free, but Celestia forced them down inside her, and stammered “Luna, I have duties I must see to. Please, clean up after yourself before you leave.”

The princess of the sun hurried out of the room, and, taking the door handle in her magical grasp, she pulled it shut behind her with a bang.

When she reached the hallway, she let out the pent-up breath that she had been holding in since Luna began her advances, and leaned against the wall, her knees suddenly going weak from exhaustion. Her mind whirled, and she pushed the thoughts deep into the back of her mind.

How on earth was she going to explain this?

Author's Note

So this was a pretty spicy one. It looks like somepony is starting to have certain feelings for her sister. We shall see how this plays out in the next chapter.

Chapter 2

Princess Celestia wandered through Canterlot Castle gardens, humming to herself. She glanced up at the sky, in which the sun that she had raised earlier that morning was burning brightly.

Pacing slowly through the neatly trimmed hedges, she took a deep sniff, inhaling the scent of the flowers that grew on them. A smile formed on her lips, and she turned the corner to see Luna almost face to face with her.

“Good morning sister,” she greeted. “I trust you had a restful sleep. You always were the type of mare to obsess over things that kept you up at night.”

Luna turned to her sister and smiled. “Of course. I had a wonderful sleep, Celestia. Thank you for asking.”

“It is my duty to ensure that my precious sister is well.” Celestia stroked Luna’s mane with her gold-tipped hoof. “After all, I do not wish to lose you again.”

Luna blushed at her sister’s touch, and smiled. “Nor I, sister,” she said, smiling and nuzzling into her sister’s hoof. “I could not bear to lose my precious sister.”

“Sister, I have something to confess,” Luna murmured.

Celestia smiled and gazed at her sister. “What is it, Luna?” she asked.

Luna blushed, her cheeks turning a bright red colour that was easily visible through her dark blue coat. “W-well, you see…” she turned away and blushed harder.

“Sister, what is it? You can tell me.”

“I-I know. You see, sister… I have been having these feelings.”

Celestia grew curious and looked at her sister. “Feelings? What kind of feelings?”

“Romantic feelings. S-sexual feelings.”

Celestia smiled and nuzzled her sister’s cheek. “That is perfectly natural to have those feelings, sister,” she said. “If I may, who is the focus of these feelings?”

“Well…” Luna trailed off and looked away.

Celestia took Luna’s chin in her hoof and turned her head to face her. “Sister, what did I say? You can tell me anything.”

Luna blushed. “I know, sister. It’s just that these feelings aren’t exactly… normal.”

Celestia looked at her sister curiously. “Whatever do you mean, sister? Who, if I may ask, is the focus of such emotions, that you would say such a thing?”

Luna took a deep breath, her heartbeat thundering in her ears. She exhaled with a whoosh, and her chest deflated with a rush of air. “It’s… you, sister.”

Celestia froze. “Whatever do you mean, dear sister?”

“I’m in love with you, Celestia.” Luna said, her hooves shaking, and she struggled to keep herself standing. “I can’t stop feeling this way about you.”

Celestia nodded. “I see.”

“That’s it?” asked Luna. “Is that all you have to say?”

“I am afraid I do not quite know what to say, dear sister.” She wrapped her hoof around Luna’s shoulders and sighed. “I love you, I do. Just… not in that way.”

Luna nodded. “I see. Then… what am I going to do about this?” The dark blue alicorn swished her starry tail across her behind, revealing her glistening entrance, which was leaking its fluids onto the grass.

Celestia’s eyes widened. “Y-you got that way… because of me?” she asked.

“I love you Celestia. Every time you’re near me, my loins burn with lust and want. When I stormed off the other day, it was because I didn’t want you to see… this.”

“Oh, Luna, it’s OK… You don’t have to be embarrassed about it. It just means you’re attracted to mares as well as stallions, and that’s fine.”

“No, sister, you don’t understand. I don’t get this way with other mares. Just you.” She smiled and swished her tail across her nether regions skittishly.

“But sister, we can’t! It’s not right! Think of the scandal if this got out! The entire kingdom would fall into anarchy!”

“I know, but I can’t hold back anymore, sister. If I have to bottle up my feelings any more, I feel as though my heart may explode! My nether regions are burning, and I can’t sate my desires with my own hooves.”

“Well then. I suggest we go inside, and I shall aid my sister in her endeavour.” Celestia smiled and lifted a hoof to gently caress her sister’s dripping behind.

Luna yelped and instinctively jumped away, but when she realised that her sister was trying to help, she backed into her sister’s hoof, attempting to drive it into her dripping nethers.

“Oh, sister, that feels so good!”

Celestia smiled and nuzzled Luna’s cheek. “I’m glad you like it, sister. And…” she paused a little before saying “I love you too. I was just thinking about the kingdom.”

Luna smiled. “I know, sister. But I’m glad that you feel the same way as I do.” She moved towards her sister and hugged her tightly. “You know, sister, I am still incredibly horny. My nethers are burning like the fires of Tartarus, and it is unbearable.”

Celestia smiled and kissed the top of Luna’s head. “Well then, shall we remedy that? My bedroom is empty, and your musk is driving me absolutely crazy.”

“I couldn’t think of anything I’d rather do, sister.” she purred, and nudged Celestias rump with her nose, getting a strong whiff of pheromones radiating from the ivory mare’s behind. “Oh, sister…”

Celestia turned to Luna and grinned. “Yes? Is there something you’d like to say?”

Paralyzed by the intoxicating scent, Luna shook her head. “No… I just…”

“Just what, sister?” asked the sun princess. “What is it?”

“You smell… incredible. I don’t know how long I’ll be able to last before I force myself on you…”

Celestia blushed and smiled. “Is it that good? Well, then I suggest we make for my chambers post-haste.”

The sun princess left the garden ahead of her sister, her nether regions radiating heat and pheromones straight into the face of her sister, who trailed behind her, struggling to keep herself standing on her weak legs.

When the two sisters reached Celestia’s chambers, they burst through the door, and hadn’t even closed the door behind them before they collapsed onto the large bed that was the sun princess’s night-time dwelling.

They straddled each other’s burning bodies, wriggling underneath the covers and when the dust settled, Luna was pinned underneath her older sister, who grinned down at her and kissed her muzzle.

“You’ve been holding out for a while now, haven’t you, sister?” she purred. “I can tell.”

Luna moaned and pushed her sister’s hoof into her nether regions. “Please… I want this. I need this.” She gasped as Celestia’s armoured hoof drove into her soaking cavern. “Oh, sister…”

“Shh,” whispered Celestia. “Leave this to me…”

The sun princess smiled and kissed her sister, pressing her into the bed. “I’m going to show you what naughty really means…”

The bedroom door slammed behind her, gripped in the amber clutches of Celestia’s magic, as the sun princess led her sister into the large chamber room, and led her to the bed. She pinned Luna to the bed and grinned down at her.

“You, sister, are about to see what I am like behind closed doors.”

Luna gulped. “R-really?”

“Yes, sister. I am about to show you what it’s like to love a real mare.”

Luna blushed furiously and looked away. “But sister… what if someone walks in?”

Celestia chuckled. “Do not worry, sister. I have sealed the door and placed a sound barrier around this room. Nobody will be able to hear us, or get in to interfere.”

“Then by all means… take me.” whispered Luna, her voice raspy and desperate. She spread herself out on the bed, surrendering completely to her sister, who loomed above her, her eyes sparkling with the lust of someone who had every intention to dominate.

The sun princess ran her hooves over her sister’s body, grinning at the moon princess’ for, which lay spread-eagled on the large bed. “You, dear sister, are about to find out what real pleasure is like. I am going to make you beg for more.”

Luna’s breath quickened, and she began to sweat heavily. “Please, sister. Give it to me…”

“Oh?” Celestia purred. “Is someone getting excited?”

“N-no, I’m not…”

“I am afraid, sister, that I don’t believe you.”

“Well then, perhaps you’d better punish me, hadn’t you sister?”

“Oh, yes. Luna has been very naughty. Luna needs a spanking…”

Celestia purred lustfully. “Oh? Is that so? Well then, I suppose I’d better oblige, hadn’t I, my pet.” The sun princess smiled and stroked Luna’s rump, which she raised high into the air, expectant of what was to come.

The ivory-coated mare smiled and gave Luna’s raised rump a heavy smack, resulting in a red welt on the princess’ backside. The princess of the night let out a squeal; a mix of pleasure and pain filled her voice. “Oh, sister!” she moaned. “Harder!”

Celestia obliged and slapped her sister’s rump again, causing Luna to bury her head in the sheets and bite down instinctively. She knew nobody could hear them, but she just couldn’t help it.

“More!” begged Luna, her voice filled with ecstasy and lust, desperately wishing to be spanked again, wanting to feel the warm fluids of her sex dripping down her thighs and staining the bed on which she was knelt.

Celestia laughed and grabbed her sister’s chin, turning her to face her, and kissing her forcefully. “You’re a naughty mare, aren’t you sister? You love to be punished.”

Luna entwined her tongue with her sister’s, and pushed back a little, forcing her off of her and wrapping her hooves around her neck. “I do. I love to be punished.” she breathed, her voice raspy and tired.

“I love you, sister,” she panted lustfully. “I don’t care what the kingdom thinks of our relationship.”

Celestia moaned against her sister’s lips. “Oh, sister, I don’t care either! It turns me on to be naughty like this!”

She broke the kiss and dove her head between Luna’s spread hind legs, attacking her dripping pussy with her tongue and furiously eating her out, listening to the ecstatic moans which slipped from her sister’s parted lips.

“Sister…” panted Luna, struggling to breathe. “Stop… I can’t… breathe…”

Celestia stopped eating out her sister, and smiled. “Tell me, Luna. Have you ever been… penetrated before?”

Luna blushed and shook her head. “No, sister, I haven’t. But how are we going to…”

Her voice trailed off as Celestia got off her to rummage in the bottom of her closet, before returning with a plastic mould of a stallion’s cock strapped around her rump.

“Sister, are we really going to…”

“Yes, sister. I want to fuck you like you’ve never been fucked before. I want to be the first pony to feel the insides of a princess like you...”

Luna grinned, her eyes shining with lust and want. “Then allow me to make it easier for you, sister.”

She turned and put her forelegs on the bed, displaying herself to her sister, who stood behind her, grinning. The deep blue mare’s vulva winked excitedly, and Celestia grinned.

“Naughty little filly.” she purred. “You have been very bad indeed.”

Luna giggled. “I know. I’ve been naughty, haven’t I sister?”

“Very naughty,” Celestia agreed. “You’ll learn soon enough not to do it again when I’m through with you.”

Luna got excited at the sound of her sister’s voice, and her pussy began to drip with lust juices. She whined softly, and craned her neck to look at her sister, who simply grinned, and nibbled on her sister’s flank.

“Oh, sister!” moaned Luna, struggling to keep herself from losing control completely. “Just take me already!” Her voice almost begged Celestia to enter her, and the sun princess happily obliged. She mounted her sister and pushed the makeshift stallionhood into her sister’s soaking cavern.

Luna moaned wildly, and pushed her flank excitedly into her sister, forcing the makeshift cock deep inside her. The tip assaulted her insides, and she instinctively bit her lip to fight against crying out, even though she knew that nobody could hear her sex-driven moans.

Celestia smiled and thrust harder into her sister’s pussy, eliciting louder moans from the almost frothing mouth of the dark blue alicorn. “Sister!” she moaned wildly, “Give me more! I’ve been a naughty little filly and I need to be punished!”

Obliging to her sister’s request, the ivory-coated mare quickened the pace of her thrusting, determined to reach as deep as she could into her sister’s cavern, which dripped with her lustful fluids, staining both the dildo and the carpet on which they stood with the naughty juices.

“Sister, you’re so good!” moaned Luna, in complete ecstasy as she was held at the mercy of her domineering older sister. “Make me yours!”

The ivory mare thrust harder into her sister’s sopping wetness, the fake stallionhood making a dirty slopping sound as she pulled in and out of her sister, the younger mare’s sex fluids dripping down her legs and pooling beneath her feet, in a mess of fluids that drove Celestia wild with their musky scent.

“Oh, sister, I never knew you were this filthy.” purred the older mare, leaning into her sister as she thrusted and biting her ear playfully. Luna squealed in pain at first, but she soon began to enjoy the sensation, and begged for more.

Celestia obliged, and nibbled on her sister’s ear, simultaneously thrusting the dildo into her sister and enjoying the sound of her moans.
“Sister, more!” begged Luna, pushing back against the assault she was receiving from the makeshift penis strapped around her sister’s rump.

“Oh, sister, I never realised sex was this good!”

Celestia grinned, thrusting harder into the drooling, dribbling mess that was her sister, and feeling her loins burning with pleasure. “I love you so much, sister!” she moaned, oblivious to anything but the pleasure that coursed like fire through her nether regions.

Luna screamed in pleasure as her sister thrust hard into her, hitting her womb with violent strokes of the phallus strapped round her rump. Her insides were on fire, and she wasn’t sure how much longer she could hold on before she…

An ear-splitting scream erupted from Luna’s mouth as she came, and her body went completely limp beneath her sister, who smiled and pulled out of the pleasure-stricken alicorn, planting her hooves on either side of her sister’s head.

“Sister, was that good?” she asked, knowing full well what the answer would be.

Luna moaned in ecstasy, using the last of her strength, which had left her long ago, to nod her head slightly.

Celestia smiled and kissed her sister lightly on the lips, her tongue wrestling with hers, exploring every crack and crevice of the younger alicorn’s mouth, tasting her spit and pressing her into the bed.

The younger alicorn found renewed strength in that kiss, lifting her head and kissing her sister back, forcing herself up off the bed and tackling her sister to the ground, pinning her beneath her. “My turn…” she whispered, grinning.

Celestia purred lustfully at her sister’s sudden boldness. “Oh, Luna…”

The younger, blue coated alicorn grinned and kissed her sister’s muzzle, flicking her tail across Celestia’s burning nether regions and making her gasp in pleasure. “Sister…”

Luna smiled and kissed Celestia again. “Yes? Something wrong, dear sister?”

“T-that feels so good… I want, no, need more…”

“Would you, perhaps, like me to use the same tool?” asked Luna, a seductive hint creeping into her voice. She kissed her sister again, and smiled.

Celestia leapt up, almost smashing her sister in the mouth. “Oh, yes! I want nothing less!”

Luna grinned and slid underneath her sister, running her hooves across Celestia’s white underbelly and deftly unclipping the phallic tool from her sister’s rump. It fell to the ground, but she didn’t stop there.

Her hooves reached Celestia’s backside and caressed her teats, flicking her nipples with her silver-shod hooves. She felt a violent shudder of pleasure run through her sister’s body, and the sun princess moaned in ecstasy.

“S-sister…”

Luna grinned. “Yes?”

“Stop… I’m going to c-cum…”

Luna’s grin widened and she deftly flicked her sister’s nipples with her hooves, massaging her aching teats. “N-no… I can’t hold on much longer…”

“Really? Is that so, sister? Then you’d better make sure I don’t do this.”

Luna mouth closed on her sister’s nipple, and she began sucking vigorously, sending shockwaves of pleasure through Celestia’s entire body. Her legs began to shake and she struggled to keep herself standing as the pleasure she felt coursed like lightning through every nerve.

“S-sister… I-”

“Yes?”

“I’m going to… c-cum!”

A torrent of sex fluids cascaded from between Celestia’s hind legs, and she screamed in pleasure and ecstasy. “Oh, my! Luna!” Her hind legs gave out and she sank to her haunches, panting heavily. “Oh… That was… amazing…”

Luna smiled and nibbled on her sister’s neck. “I love you, sister. We should do this again.” She smiled and lay down beside her sister, licking the mess of sex fluids that had matted into her ivory coat.

“Luna… don’t. That’s dirty…”

The night princess smiled and continued licking her matted coat, tasting the strong flavour of her sister’s sex fluids. “Oh, sister… you taste so good!”

“Luna! Don’t say things like that! It’s… embarrassing.”

Luna smirked and licked the trail of juices that was trailing down her sister’s hind legs. The taste of it was strong and tangy, the flavours playing on Luna’s tongue. The smell of her sister’s sex juices closer to her pussy drove the dark blue alicorn crazy, and she felt herself becoming drenched between her hind legs.

“Oh, Celestia…” she gasped. “You taste really good, sister.”

“Luna!”

The starry-maned alicorn looked at her sister and smiled innocently. “What is it, dear sister? Whatever is the matter?”

“Don’t speak like that! It is unbecoming of a princess of Equestria.”

“Oh, please, sister. I think we threw etiquette out the window a [i[long time ago. Don’t you?”

“Oh, absolutely. If the kingdom knew of our relationship, I am sure that they would have our heads on spikes and mounted in the town square.” Celestia shuddered at the thought, and pushed it to the back of her mind, focusing once more on the pleasure that was spreading through her hindquarters as her sister licked her rump clean of the sex fluids that coated it.

Luna smiled and lapped her way up her sister’s hind legs, eventually reaching her dripping entrance, and a small smile formed on her lips. The sex-driven mare plunged her tongue into her sister’s wetness, and an intense tingling consumed her tongue.

She drove it deeper inside her sister and Celestia screamed in ecstasy, sinking back onto her hind legs as she was unable to continue standing.

“Luna…” panted Celestia. “I think… we should… stop. I can’t… take much more…”

Luna scowled at her sister and a small smile played on her lips. She kissed her sister passionately on her lips, and climbed on top of her. “Oh, sister. You always were the one to ruin my fun.”

Celestia laughed and kissed her sister back, pulling her to her and wrapping her in her forehooves. “I am afraid I am unable to continue, dear sister. Much as I would love to, I am afraid that I cannot.”

“Oh, sister, you’re such a buzzkill.” Luna sighed and rested her head on Celestia’s chest, listening to the rapid thudding of her heartbeat. She smiled and kissed her way up her sister’s chest, reaching her lips and smiling. “I must have worn you out, huh sister?” she smiled.

“Oh, yes. Very much so. I might even have to recoup at Ponyville Spa after this.” she smiled and kissed her sister back.

Luna’s eyes lit up at the thought of being pampered at the spa. “Mind if I join you?” she asked excitedly.

Celestia nodded.

“Sister,” she whispered softly.

“Yes?”

“I love you.”
