1.) A Princess Always Pays Her Debts
~~~ A Princess Always Pays Her Debts ~~~
~~~ By Spinner of Tales ~~~
Celestia couldn’t have asked for a better night to spend with her sister.
It was gorgeous. The night sky was clear, and the moon soared high above the tallest tower of Canterlot. A crisp breeze blew through the air, and Celestia knew she would have been cold, if not for the pony snuggled up next to her.
Luna gave her sister a light tug with her right wing and pressed a little closer into her side. Celestia cooed appreciatively. Goddess, they didn’t get to spend enough time like this, just the two of them. Luna extended her forehooves and motioned her head down to them, smiling. Celestia grinned, and lowered her head onto the waiting makeshift pillow.
A tongue, wet and just a little bit rough, pressed against Celestia’s ear and licked. Like a mother cleaning her newborn foal, Luna closed her eyes and groomed her sister. Celestia couldn’t suppress a small gasp at the sensation. She lifted her head and shot Luna a quick smile, before leaning in and kissing her sister’s exposed neck. And then, she lay her head back down on her sister’s offered hooves and closed her own eyes. The grooming resumed.
She had meant it, of course. The two of them, sitting like this in peaceful silence, overlooking the fields outside Canterlot… It didn’t happen often. Less so, with the various crises the princesses had to face on a week-by-week basis. Sometimes, Celestia thought, it was good to be forced to relax, to slow down and smell the flowers. Or, in her case, her beloved sister’s perfume. Was that lilac? Rose? Celestia couldn’t tell.
The elder princess shivered as Luna’s head ducked beneath her wing. She tensed, and then relaxed, as her younger sibling began to preen her. Luna nibbled at the spaces between her wings, targeting the many tense bundles of nerves at her sides. Nip followed suck followed light, fleeting kiss, and Celestia soon found her wings fluttering of their own accord. Her face flushed, and she cooed in happy contentment.
More and more Luna preened her, and Celestia soon found her eyes and ears drooping. She snuggled into Luna’s forehooves a little bit more, reveling in the warmth they provided. Her eyes squeezed shut, and a rather loud yawn escaped from her mouth.
Moments later, she heard Luna giggle.
“What?” Celestia asked, raising her head as best she could. Luna continued to preen her.
“Nothing,” Luna said, then bit down on another feather. “It’s just so adorable, the way your face scrunches like that,” Nibble. “You’re so cute sometimes.” Kiss.
Celestia felt her cheeks heat up at the compliment. Luna thought… she was cute? Her heart fluttered in her chest. “You’re silly,” Celestia said. Once again, however, she felt her eyelids become heavy. She knew sleep was inevitable. She was just putting it off now.
“I love you, Tia.”
Celestia kissed the top of Luna’s forehoof, the only thing she could reach in her current position. “You too, Lulu…” She murmured. “You too.”
And then, all was black.
Celestia opened her eyes.
She was in her room. Not in the fields outside Canterlot. Not snuggled up to Luna. Not being groomed by her sister. Not being… loved. A twang of sadness pricked at her heart. So it had all been a dream.
But… just then, there was a smell. It took Celestia a moment to figure it out, but once she did, all of the sadness in her heart dissipated. It was the smell of love, and it was all over her bedsheets.
“Well, at least it wasn’t all a dream,” Celestia smirked. Her sister had come to her last night, and they had made love. Her smirk turned into a bona fide smile, and the solar princess felt her heart flutter into her chest. Luna still loved her, just as she had in the years prior to her… incident. A chuckle escaped Celestia’s smiling lips, and then, a faint laugh. She reached over and pulled one of her pillows to her chest, and hugged it tight, rolling around on the bed. Her sister loved her! Her sister loved her!
Eventually, however, Celestia settled down. She set the pillow aside, and fully sat up. She glanced around the room. Where was Luna? The last time she had seen her younger sister, Luna had been snuggled around her waist as she drifted off to sleep. Truth be told, Celestia was somewhat hoping that she would still be there; that Celestia could run her hoof through her mane, and just snuggle like they had in the old days.
Lighting her horn, Celestia tugged the curtains on her window open. She was greeted by a most unpleasant sight.
“Gah!” She cried, stepping backwards and throwing up a hoof to cover her eyes as bright sunlight streamed through the window. So that’s where Luna had gone. She had raised the sun, and allowed her big sister to sleep in.
“Remind me to thank her,” Her mind told nopony in particular. “Though she still has much to learn about raising the sun.” Celestia lowered her hoof and, illuminating her horn once again, used her magic to turn the sun down several levels of light. “Shouldn’t be like that until noon, never mind breakfast.”
Her eyes opened. “There,” She smiled. The sun was now a yellowish-goldenish color, and a lot less intense. Her little ponies could wake easily now.
But, since ponies were waking, that meant that they would soon start coming to court. Which meant that Celestia had to start getting ready for her day. She surrounded her horseshoes and her tiara with a golden glow, and levitated them closer. She lifted one hoof to put it in the shoe, and then…
Crack.
Celestia stopped. Her ear twitched. What had that been? She hadn’t… broken something, had she? She didn’t feel any pain. Shrugging it away as a mid-morning hallucination (she had a ton of those), Celestia lowered her hoof into the…
Crack.
This time, Celestia felt something. It was the fur surrounding her thighs, and it was… cracking? Curious, the princess lowered her gaze to examine her lower regions.
“Oh,”
The entire area surrounding her marehood was surrounded with… evidence. Evidence of her and her sister’s illicit union the previous night.
"Perhaps I ought to take a nice, long shower," Celestia thought. Being covered in her and her sister’s cum was… unbecoming of a princess, to say the least. And while it would have been a lie to say that Celestia didn’t find the prospect of marching into the throne room covered in her sister’s cum and scent, marking her as Luna’s and Luna’s alone, to be at least a little bit appealing, it just wouldn’t do. What if the servants were to see?
Celestia took a towel into her magical grasp and trotted toward the bathroom. And then, she heard something which caused her to stop in her tracks.
Her shower was already running. Somepony was in her personal bathroom, using a shower. Celestia couldn’t help but smile as she realized who that somepony could be.
She could take a shower with Luna! The thought coalesced in her mind, giving her a small, giddy smile. Much like it had been in her dream, Celestia would like nothing more than to snuggle into her sister’s side and allow her to clean her. Perhaps… perhaps Luna would allow Celestia to groom her as well? It had been ages since they’d done that together! Or... Celestia grinned. "Perhaps I could give her an orgasm? After last night, I think I should do something nice for her. I do owe her." She reasoned.
It was only fair, after all. Her father, Faust rest his soul, had always told her: "You are a princess, and a princess always pays her debts." Luna had given her an excellent orgasm, so Celestia owed her an excellent orgasm in return! It was a just and honorable rule, and Celestia was a just and honorable ruler.
It was settled, then. An orgasm for an orgasm. Celestia bit her lip as she dropped into a crouch and began sneaking toward the bathroom. Naughty thoughts invaded her mind. She would sneak up on her sister, surprise her with a kiss on her cutie marks, and then --
Luna’s singing caught Celestia’s ear. It was an old tune, one from centuries ago. And while Celestia couldn’t recognize the language it was sung in, she was nonetheless enthralled. She loved Luna’s voice. It was rich, yet still feminine, tickling the edges of Celestia’s ears and making her smile. It was almost too bad that Celestia was about to transform her sister’s gorgeous singing voice into the pleading whinnies of a desperate lover.
Celestia stepped into the massive shower. Luna was, thankfully, still unaware of her presence. She continued to sing in that wondrous voice of hers. A magical comb weaved through her the individual hairs of her ethereal mane, and with every stroke, a comfortable smile spread across Luna’s muzzle. Inch by inch, Celestia crept closer and closer. The tip of her tongue poked out from in-between her lips. She could hear her heart beating in her own chest.
Finally, she was there, a mere breath away from her sister’s most private parts. Luna’s tail flicked out of its own accord, leaving Celestia with an unobstructed view of her slit. It was a little puffy, but not aroused. Not yet. Celestia bit her lower lip; she would soon take care of that.
Feeling her own tongue running across her lips in anticipation, she leaned in, pressing the tip of her muscle against Luna’s slit. The younger princess tensed. She gave a small gasp, turning her head back so that she could see the intruder probing her most intimate of places, though her muscles soon relaxed as she saw Celestia smiling back at her. Celestia winked at her, and delivered a long lick, straight from the top of Luna’s slit to the bottom. Luna’s right hind leg twitched, and her tail, on instinct, rose a bit higher. Celestia was pleased to see the tip of Luna’s clit poke out from between her folds. Smiling, she took it in her lips and delivered a few flicks of her tongue, each one lingering longer and longer and drawing random shapes over the little pink nub, until eventually she pulled away. A small strand of saliva connected her lips to her sister’s clit, though it was almost immediately washed away by the shower. Celestia once more leaned in and gave her sister’s folds a delicate kiss.
“Did you enjoy the dream I bestowed upon you, dear sister?” Celestia looked up, and found Luna’s gaze meeting hers. A blush had spread across the younger alicorn’s smiling, demure muzzle, and her ears seemed to flick back and forth.
In response, Celestia nuzzled against the moon emblazoned on her sister’s flank before stepping under the stream of hot water to stand beside her. She pressed her lips against Luna’s, closing her eyes and allowing the water of the shower to wet her mane as she kissed her beloved sister.
She pulled away and opened her eyes. Luna looked up at her, a smile on her face. With the water running down her mane and wetting her muzzle, Luna looked beautiful. It brought a flutter to Celestia’s heart as well as a longing desire to fully love and be loved by the pony in front of her. “Oh, yes,” Celestia leaned in towards her sister’s ear and whispered, giving her a small lick and kiss. “I enjoyed it so, so much, Luna.”
Luna answered with a giggle, kissing the underside of Celestia’s chin. Their gazes met once again, and Luna gave the elder alicorn the most caring smile she could muster. “Now that you are awake, I would be more than pleased to actually preen you. If you so desire, of course.”
Celestia smiled. She took one of her hooves and rubbed it tenderly against Luna’s cheek. She stared into her sister’s gorgeous teal eyes, before leaning in and capturing her lips in another kiss. Celestia took her sister’s bottom lip in hers, and suckled on it for a precious few moments, before she stopped and regarded her sister. “I think,” She said, stopping to take a breath she hadn’t known she’d needed. “That while being preened by you would be wonderful, there is one matter I must attend to first.”
Luna must have noticed the sultry tone in Celestia’s voice, for when she answered, her voice was laced with no small amount of coyness and an equal amount of desire. “And what might that be, dear sister?” She asked.
Something in the corner of her vision caught Celestia’s attention. Her younger sister’s tail was beginning to twitch erratically, and Luna’s hind hooves were doing the same. And so Celestia smiled down at her sister. “I could tell you,” She grinned, capturing Luna’s mouth in one more kiss. This time, she slipped her tongue inside Luna’s mouth, tasting the younger alicorn’s saliva and teasing her tongue for the briefest of moments before she pulled away, leaving a dazed but happy smile on Luna’s face. “Or, I could show you.”
The elder alicorn could see the color rush to Luna’s cheeks. Giving her sister a wink, Celestia moved away, allowing her tail to tease Luna’s muzzle as she moved behind Luna’s rear.
Using a foreleg, Celestia spread one of Luna’s back legs, then the other. “Keep your hind legs spread wide, Lulu,” She cooed and dared a glance over Luna’s rump. Her sister, looking back in eager fascination, licked her lips and turned her head back around. She raised her tail as high and to the side as it could go, allowing Celestia free and unfettered access to do whatever she pleased.
Celestia nuzzled the inside of Luna’s right thigh, feeling the short, coarse fur of her sister’s most intimate area rub against her cheek. She moved up, just a little bit, and planted a small, tender kiss just on the edge of her sister’s pussy, not quite touching the edge of her labia. Celestia heard Luna take in a deep breath, and grinned, an idea popping into her head.
Deciding to tease Luna, just a little bit, Celestia exhaled onto the quivering petals of Luna’s delicate marehood. The hot air on her outer lips sent a shiver running up Luna’s back and through her body. But then the elder alicorn moved away from her beloved sister. In response, Luna whined, and shook her rump a little in every direction, hoping to reconnect her pussy, which was now starting to leak a clear, thin liquid, with the muzzle that had just been so close to caressing it.
“Patience, Luna,” Celestia said with no small amount of effort and a slight hitch in her voice. “Good things come to those who wait.” It was advice meant just as much for her sister as it was for her. It took everything Celestia had to restrain herself, to not dive right in and taste the sweet, succulent nectar right in front of her.
“’Tiaaaa…” Luna whimpered. She swallowed prominent lump in her throat. “Pleeassseee…”
Celestia gave in, at least a little bit. She allowed herself one small kiss to the outer edge of Luna’s burning folds. It wasn’t much, just enough to show Luna that Celestia cared. But for the younger alicorn, it must have been a burning hot coal of pleasure, applied right where Luna needed it most. Her whole body shook as it was wracked with pleasure, and Luna immediately tried to back up, to shove her sister’s muzzle inside of her. However, a firm magical presence seemed to root her in place, preventing her movement. Luna cleared her mind just enough realize what had happened, and to look down. Golden magic covered each of her hooves.
“I told you,” Celestia nickered. Each one of the breaths against her pussy sent shivers straight up Luna’s spine. “Y – you need to be p - patient…”
Celestia smiled when her younger sister’s pussy winked back at her for the first time that morning. She could see, just a little bit, of Luna’s inner muscles at work, churning in desperate need. And Luna’s juices were at work, preparing her to be rutted and mated and bred like a good little filly. Several droplets of clear liquid gathered at the base of Luna’s marehood, covering her clit in a glistening, sticky sheen. It began to fall, and Celestia, not wanting such a delicious mixture to go to waste, lapped it up as it hung, suspended from her sister’s gorgeous snatch.
It was at this point that Celestia became aware of the burning in her own loins. She was positive that she was dripping just as much as her sister, if not more so. Half of her wanted to reach a hoof back there and take care of her own business. Perhaps she would lick the cum off of her own hoof. Or she could have Luna lick her clean. The thought of Luna’s tongue against the sole of her hoof, sucking on the short fur and taking Celestia’s cum into her own mouth… The fantasies made her shiver. However, she found one of her fore hooves travelling down her stomach, and she forced it back down to the ground. “Patience,” She told her raging hormones.
“I am being patient!” Luna practically screamed into the shower, her own front hoof stomping desperately against the marble floor. Celestia once again looked over her sister’s rump, daring to glance at her beloved sister’s face. Luna’s eyes were squeezed shut, her mouth hung open and needy pants escaped her with every breath she took.
Celestia once again went in, peppering Luna’s thighs and legs with kisses and licks. With each application of pressure, Luna’s hindlegs kicked and her tail twitched. Her wings, now fully erect, trembled in anticipation. Her breath caught. Having Luna here, in the shower, her legs shaking, her wings at full mast, sent one thought and one thought only through Celestia’s sex-addled mind.
“Screw patience,”
It was time. Celestia took a deep breath and focused a portion her magic on Luna’s labia. The golden glow latched on to her sister’s outer lips, spreading them apart and revealing the treasure trove of delicious nectar within. Hot, sticky, clear strands of Luna’s juices clung to the walls.
At the sudden exposure of her innermost regions to the cold air, Luna gasped in loud, pleasurable abandon. “Oh, yes!” She cried, squirming against the magic still holding her hooves down. “Yes! Celestia, please!” Her rump almost fell backwards in a desperate attempt to impale her pussy on her sister’s tongue.
And then Celestia dove in. Her tongue ran up and down the insides of her sister’s walls, lapping up the massive collection of fluids that had accumulated inside of her. She loved Luna’s taste. It was sweet, and she found that she couldn’t compare it to anything in the world. Nothing tasted quite as good as her sister. And so she drank. She swallowed as much of her beloved sister’s juices as she could, licking along the inside of Luna’s pussy all the while.
Each lick caused Luna’s breath to hitch. Each kiss and suckle sent her heart fluttering higher and higher in her chest. She was shaking fully now, practically seizing against her magical bindings. Sensing her sister’s need, Celestia, with a single thought, released the magic holding Luna’s hooves to the floor, granting the younger alicorn the freedom to do whatever she needed to do, without reservation.
Luna jumped backwards, driving Celestia’s muzzle ever deeper inside of her sopping wet marehood. A throaty moan escaped the young princess. Luna then collapsed onto her forehooves, burying her muzzle inside her forelegs and moaning like a common mare in heat. She kept her firm ass presented and her tail raised for her sister to ravage and lick and kiss and love. A strong lick against her clit caused Luna to raise her head up from the ground. “Yes!” She cried, her voice practically dripping with lust. “Oh, Celestia! Yes, yes!” She panted, her breaths heaving as Celestia began to alternate between tonguing her slit and sucking on her clit. She shook her rump furiously. “Fuck me!” She cried, oblivious to her profane, un-princesslike language. “F – fuck me!” Her voice stuttered as her breath caught in the midst of her scream. “Y – Yes! Yes, I aaahhnnnn!” Her cry trailed into a desperate moan. “Ah! Yes!” She panted. “Fuck me, fuck me, please… harder, harder, harder!" Her eyes rolled into the back of her head as Celestia’s tongue ravaged and had its way with her.
Luna’s pussy wouldn’t stop winking. Each contraction sent a fresh supply of nectar into Celestia’s muzzle. Each time her sister cried out, each time her sister’s pussy contracted around her tongue, pulling her further and further in, Celestia’s vision became more and more hazy, more poisoned by the sweet smell of love and lust which now permeated the steam-filled shower room.
Celestia pulled back, but only for a moment. She regarded her sister, panting, moaning, squirming, presenting her pussy and her ass, begging, pleading to be fucked, imploring Celestia to give her the orgasm her body needed. She regarded the strands of her sister’s juices connecting her muzzle to Luna’s dripping, winking, pulsing, puffy pussy.
That was it. Celestia would not – could not - deny her beloved sister any longer. Her mouth returned to Luna’s clit. Her lips wrapped around the pulsuing nub and she sucked, humming as she did so. And then she channeled some more magic into her horn and enveloped Luna’s entire marehood in a golden, vibrating glow. That sent Luna over the edge.
“Tiiiaaaaa!” Luna screamed into the shower, her entire chest seemed to harden, and her limbs seemed to lock in place. “Aahhh!” Tear-filled eyes rolled back into Luna’s head, and she ground her pussy into Celestia’s muzzle as she came. Her inner walls contracted, and waves upon waves of white-hot pleasure wracked her body as Celestia shoved her tongue, once again, inside Luna’s marehood, thrashing with wild abandon.
The first volley of Luna’s thick marecum painted the inside of Celestia’ cheeks. She continued to lick and suckle even as the second and third shots filled her muzzle to capacity. The fourth and final spurt, having nowhere else to go, escaped the seal created by Celestia’s lips and sprayed all over her cheeks, coating Celestia’s muzzle in the scent of the mare she loved.
Luna, totally paralyzed by pure pleasure, collapsed onto the floor of the shower. Panting, quivering, shaking, writhing on the marble floor, she almost didn’t notice Celestia walking over to her on shaky legs, before sitting down right next to her and opening her mouth.
Once again, Luna’s breath caught. Celestia’s mouth was filled to the brim with warm, sticky marecum. Her cum. And Celestia smiled at her younger sister and closed her mouth and her eyes. She swashed Luna’s cum around for a few moments, reveling in the delectable taste, and then swallowed, giving her sister an audible gulp. Luna watched with rapt interest as the small bubble of marecum disappeared in a lump down Celestia’s throat before disappearing into her body.
“T – T – Tia…” She tried to speak, but was interrupted by periodic spasms throughout her body, causing her breath to hitch. “I l – love…”
Celestia held a hoof up, pressing it against Luna’s muzzle. “Shh,” The elder sibling whispered. “It’s okay,” In an instant, the hoof was replaced by Celestia’s lips.
It was only a matter of time, however, before Celestia’s lust overcame her own tender feelings. Luna couldn’t suppress a happy moan when her sister’s tongue pressed up against her teeth, asking for entrance. She grinned into the kiss as she opened her mouth. Luna could taste her own cum mixed in with her sister’s saliva. It was among the most exotic sensations she’d felt in a long, long time.
“Luna,” Celestia broke the kiss and whispered into her sister’s ear. “Lulu, I need you… I can’t… I can’t take it anymore…” She took a deep, shaky breath. “Please… love me?” Her words weren’t a demand. They weren’t really a request. They were a plea, a begging plea.
Luna nodded, her eyes full of sympathy. “Let’s dry off,” She said. “And go to the bed. I think you will be pleased with what I have in store for you.”
Celestia’s eyes widened in anticipation, and her pussy contracted, squirting the smallest bit of cum onto the floor. Her tail swished it around. What could Luna have planned? Would she use her magic? Her hooves? Her tongue? Each fantasy that played out sent a massive shiver through the elder alicorn’s body, straight to her quivering, dripping, and burning marehood.
Luna lit her horn, and turned the shower off. She rose to unsteady hooves, still sensitive after the orgasm she’d experienced. A quick magic spell from Celestia dried the both of them. She didn’t want to waste time performing such menial tasks. Although, she couldn’t deny that having Luna dry her would be at all unpleasant. Especially if she knew just where to rub that towel.
Celestia was snapped from her fantasy by the arcane tingle of Luna’s tail as her sister trotted by her. The tip of the tail tickled along Celestia’s side, up her neck, and across her cheek, and Celestia’s gaze was drawn to meet her sister’s. Luna gave her the sexiest ‘come-hither’ look Celestia had ever seen. Luna twitched her tail, allowing Celestia to see her sister’s still-aroused pussy. It winked, and Celestia practically galloped from the bathroom to follow the younger alicorn.
~~
Celestia felt giddy with excitement as she hopped up onto her giant bed. Looking back, she saw Luna making her way towards her. What would Lulu do to her? The possibilities were endless!
Luna crawled up on top of the bed, and approached Celestia. Soon, she had a hoof on either side of her elder sister’s neck, and she looked down upon Celestia with a passionate, loving gaze. Celestia’s body squirmed, eager to press against the body above her. Luna leaned in, close enough that Celestia could feel her lover’s hot breath on the tip of her nose. “You have been a bad filly, haven’t you?” She cooed. Celestia felt a shiver shoot straight up her spine, and she froze. A… bad filly? What was Luna talking about? “Forcing me to endure such cruel torment…” Luna gave a quick lick to the wet tip of Celestia’s nose. “Teasing me so, so much… I think you need to be punished.” Celestia’s hot marehood clenched in anticipation. What would Luna do? Spank her? Sink her teeth into her flank? She bit her lower lip.
It wasn’t until it was too late that Celestia felt it. Her own bedsheets had begun to move and twist, forming thick, ropelike structures that, in a single instant, had tied themselves around all four of Celestia’s legs and had fastened her to the bed, pulling her hind legs wide and exposing her puffy slit to Luna. Another cord, from where Celestia had no idea, secured her wings to her sides. As much as she tried, and try she did, there was no escape from Luna’s bindings. Her wings strained against the rope, and her hooves struggled against the bedsheets tied around them, all to no avail. She looked up at her sister, her beloved princess. Celestia’s eyes were wide, and her ears flicked back against her head.
The younger princess leaned down towards her with a lustful gleam in her eyes. “There you go,” She said. “Now… how shall I begin?” She nickered into Celestia’s ear, before she captured her elder sibling’s lips in a deep kiss. In an instant, Luna slipped her tongue fully into Celestia’s mouth, licking along the perfect teeth it found.
Celestia’s tongue soon found Luna’s, and engaged it in a wet, sloppy battle for dominance. Celestia could taste her sister’s delicious saliva mixing with hers as the kiss dragged on, and their mouths became more and more filled with each other’s fluids. Suddenly, Luna took Celestia’s tongue into her lips and suckled, drawing a loud and needy moan from the elder alicorn. In response, Celestia lit her horn and tried to pull her sister’s tongue further into her mouth using the only remaining means at her disposal. All in all, that may have been a mistake.
As soon as Celestia applied pressure to the back of Luna’s head, the younger princess let her tongue go. Despite a vocal whine of protest from Celestia, Luna pulled back from the kiss, a non-serious frown on her face as she looked down at her sister.
“Oh, my. It would seem as if I’ve forgotten something” Luna smirked. Luna lit her own horn, and Celestia felt an odd, magical pressure against hers. In an instant, the strange feeling was gone, and Celestia gave her sister a confused look. “We cannot have you using magic right now, can we?” She asked. Celestia’s eyes widened.
Celestia tried to send a pulse of magic to her horn. Sure enough, nothing happened. Luna… Luna had cast a magical inhibition spell on her! There was nothing Celestia could do. She was totally at her sister’s mercy now. Her hindlegs tried to clench, and her tail flicked about on the bed, swishing through a rather large collection of fluids pooling just underneath Celestia’s pussy.
“Now I can begin.” Luna said. “I think,” Luna muttered before she leaned back down and pressed her lips back against Celestia’s for the briefest of moments. She pulled away. “Since you teased me for so long in the shower. I should tease you a little bit, too. That is fair justice, is it not?”
Luna’s hoof began to trail down Celestia’s belly, and the older alicorn squirmed under her sister’s ministrations. Each touch of Luna’s hoof was like the kiss of heaven to her, feeling her lover running and rubbing her soft hooves over her exposed stomach. “Ahh,” She moaned a little, and she arched against her sister as Luna’s hoof caressed her teat. It rubbed against Celestia’s small nipple, and Celestia looked into Luna’s eyes, utter adoration in her own as her sister sent bolts of pleasure straight to her dripping, pulsing core. Luna's hoof then went lower, trailing around the edges of Celestia's burning outer lips, teasing her desperate, winking clitoris. Celestia's muscles clenched in anticipation. "A little closer," She thought. Her breaths became punctuated by breathy pants, and for every inch downwards that Luna's hoof went, to Celestia, it may have taken an eternity to do so.
But then, Luna pulled away. Her sister let out a strangled cry as her hoof trailed back up Celestia’s stomach, up her chest, and finally, to stroke at her cheek. Luna smirked, and focused her magic.
Celestia whimpered and nickered, and her body strained against the bindings as Luna’s magic began to work over her. Her hoof began wandering once again, as well, following the trail of her magic up and down her thighs and around her teats and her sopping, dripping marehood. Her ethereal tail thrashed around on the bed, spreading Celestia’s thick wetness all over the sheets. A dark blue glow surrounded Celestia’s clit for the briefest of moments, before it vibrated for an instant and disappeared. Celestia let out a wanton moan and a whinny. Her body convulsed against her restraints. And during all of this, Luna stood, dominant, over Celestia, biting her bottom lip as a permanent, heated blush played at her muzzle.
“Lulu!” She cried, panting with heavier and heavier breaths. “Luna, p – please, I…” Her cries were cut off as Luna leaned in and bit down on Celestia’s neck, just above her collarbone. Hooves still wandering alongside magic, sending tingles up and down her spine, Celestia let out a hoarse scream, and her eyes rolled into the back of her head. She couldn't take it anymore! “Ahhh!”
Luna sucked on the spot she had just bitten. Celestia could feel her flesh being pulled into the suction of Luna's mouth. And then, Luna let go. The cold air hit her. But Celestia didn't have time to dwell on it, as Luna bit down on another spot, just a bit lower. Again, she suckled, pulled away, and wet down another inch. Each love bite left a small whorl of wet, raised fur and a small red mark in its wake. Celestia rolled and squirmed against the bedsheets every time Luna pulled away, more and more so as she went lower and lower, until Luna found her muzzle right in front of Celestia's winking, needy slit.
Celestia could feel Luna’s breaths against her labia. Each breath was like an ice-hot spike impaling her, and her pussy clenched with every exhale. She could feel her juices dripping down her slit, puddling just under her puckered hole. Would Luna lick her down there? Would Luna stick her horn inside of her? Would Luna fuck her in the ass like some common whore on the street? The prospect sent her even more crazy with lust than she had been before.
As if she had read her sister's thoughts, Luna's tongue darted out, teasing her tight asshole. Celestia's tongue lolled out of the side of her mouth, and she bucked her hips as best she could. A lurid moan escaped her. She forced her entrance to open, to show Luna just where she wanted her little sister.
The moment Celestia's entrance loosened, Luna licked around the rim, sending spasms of pleasure throughout the elder alicorn's body. Luna looked up at her sister and smiled. Her horn lit, and Celestia gasped and her hind legs tried to kick as she felt a small, magical sphere insert itself into her ass. As if on cue from Luna, the small magical egg began to vibrate, and Celestia's eyes rolled back into her head and she squealed. Luna, in turn, brought her muzzle up just a bit, hovering it above her sister's pulsing snatch.
"Say you're sorry for teasing me," Luna said, smirking. She wanted Celestia to submit to her. She wanted to hear her sister, without question, scream whatever she wante --
"I'm sorry for teasing you!" Celestia shouted in the full Royal Canterlot Voice, her hips shaking against their bindings. "Please, just... Just mate me! Rut me! Please, Lulu!"
"Who's the best princess?" Luna asked. Just how far would Celestia go to get off?
"You are!" Celestia threw her head back as another powerful breath blew against her sensitive pussy. "You're the best princess! Please, make me cum! Please, rut me! Fuck me, mate me! Just do it!"
Luna blinked. Well, she couldn't argue with a request like that. So, she began to vibrate the egg in Celestia's ass as best she could, and dove her tongue into Celestia's dripping wet snatch. The titanic scream that tore from Celestia's lips could have shattered the windows, it was so loud. Her wings, as strong as they were, finally broke through the cord restraining them, flaring to their full span. Celestia bucked her hips, each buck punctuated by another massive scream, as she tried to drive her marehood onto the tongue invading it. Her pussy clenched around Luna's wet muscle, drawing her further and further in. Luna could feel her sister's nectar coating her muzzle, and the heavy scent of a mare lost in passion filled her nostrils with every breath she took.
As she licked, one of Luna's own hooves trailed down across her belly, and caressed her own aroused pussy. A shot of pleasure wracked her whole body as she rubbed against her clit, and she moaned into her sister's pussy. The vibration of her voice mixing in with the vibration of the magical egg in Celestia's ass caused the elder alicorn to throw her head back.
Luna could feel her sister getting close. A few more licks, and Celestia would be sent over the edge. And with her pussy dripping more and more, Luna knew she was on the precipice as well. With great effort, Luna pulled away from Celestia's twitching marehood and clit and crawled up her lover's body. Locking eyes with Celestia, Luna leaned in and shoved her tongue inside Celestia's mouth, thrashing with hers as she moaned. And then, Luna dove her hips down. Her clit met Celestia's in a wet smack, and both ponies broke the kiss and cried blissfully into the room. Once more, Luna raised her hips, and once more, she brought them down.
The room was filled with the sounds of wet skin and wet fur slapping against wet skin and wet fur. Loud moans seemed to each slap, save for when both princess' lips were occupied with each other in heated kisses. Slaps gave way to grinds, and moans gave way to desperate pants and whinnies, and, with massive screams and lustful moans, both ponies came to their peaks.
Celestia came first. Her eyes rolled into the back of her head for what seemed like the thousandth time that day. Clear, thick liquid erupted from her pussy, coating the inside of her thighs and the outside of Luna's pussy as it ground against her. She felt her whole body explode in pleasure as spurt after spurt of marecum coated her, her sister, and her bed. And through it all, that magical egg still vibrated inside of her ass, making her squeak every time her breath heaved and her ass clenched around the conjured toy.
Having Celestia's cum sloshing around as she thrust was too much for Luna to take. She cried out into the bedroom, and happy tears fell from her eyes as she thrust one last time onto Celestia's pussy. Her marehood clenched over and over again, and her own thick cum spurted out, mixing with the pool of Celestia's sweet juices. Her legs shook, and her ears flicked about. A bit of drool fell from her open and panting mouth into Celestia's.
And then it was over. Luna collapsed on top of her sister, their hips squelching as a massive pool of their cum was spread across their stomachs by their connection. The two lovers panted heavily into each other's necks. They reeked of sweat and cum and the smell of love, and they couldn't get enough of it.
"We're..." Celestia swallowed. "Going to be late for the day court, you know."
Luna gave her sister a breathless laugh and lit her horn, undoing the bedsheets tied around her sister's legs. "F - Fuck the day court. Let's... stay here."
With all of her might, Celestia calmed her still-racing heart. "You know we can't do that. Ponies are depending on us."
"I know, I know." The elder alicorn felt her younger sister tense above her, and then Luna rose onto shaky legs. The still wet puddle of cum connected them for a few moments, before the strands fell downwards, splattering back onto Celestia's lower stomach and her bedsheets. "I will open day court for you, sister." She brought a hoof to her marehood, taking a sample of her and Celestia's mixed cum. "After another quick shower, of course." Luna hopped down from the bed, gasping as her legs almost gave way underneath her.
"Can... Can I join you?" Celestia asked, a hopeful look in her eyes as she got down from the bed as well.
Luna regarded her for a moment, and then, much to Celestia's disappointment, shook her head. "I don't think that would be wise," She said. "I think we both know where sharing our shower would end."
The older sibling chuckled. But then, a wholly different idea struck her. "Can we do this again? Tonight?"
Luna turned around and began walking back to the bathroom door. Just before she rounded the corner, she turned her head back and locked her gaze with Celestia. She swished her tail, flicking a bit of cum around the room and giving Celestia an unobstructed view of her marehood. "Perhaps," She said with a smirk. "Assuming you can be a good filly and control yourself during day court."
And with that, Luna was gone. Celestia heard the shower start. Her own tail flicked.
It was going to be a long, long day.
