Dear Princess Celestia...
In the dim-lit bed of her bedroom, Celestia woke up with a start and frantically looked around. "Luna? Lu?" She scanned her room for her sister, but her endeavours revealed nothing. "Oh… It was just… Geeze, what a strange dream," she muttered to herself. "I haven't dreamed anything like that for a very long time. Ever since… heh." Even in the cold of the night, she could feel her muzzle flaring up from the thought alone.
"Luna?" she repeated herself, and again, there was no response. Just a crack of wood trying to settle in the cold of the night.
Without much hesitation, she sent a sliver of magic from her horn, lighting a few candles across the room. A warm glow filled the room, including a table in the corner where she had placed a single rose and a small piece of paper with For Princess Celestia scribbled on it.
She had received plenty of those letters in the past few months, making Celestia believe she had a secret admirer among her subjects. Above all else, she was amused. It had been a great number of years since the last time she had entangled herself with anypony.
Not knowing anything about the mysterious sender just poured more fuel into the proverbial fire, and she gradually admitted that she liked it that way. She couldn't help herself but wonder who the mysterious pony was, if it was a pony she had already met, and many other questions that quite a few times chipped away at her well-deserved sleep.
She sported a small smile and closed her eyes as she took a whiff of the beautiful flower, quietly asking herself the question again, "Who are you?" Knowing that there would be no reply, she turned towards the window and looked at the dark skies, watching the last sliver of her sister's work slowly fade away. She took a deep breath and concentrated.
Just like before, she lit her horn and aimed it into the dark night, but the glow didn't stop this time. It only grew stronger and brighter until the horizon started to glimmer, and the edge of the sun started to appear on the cloudless sky. As the sun rose even higher, the light of her horn started to dim down, until it faded out completely.
She calmly exhaled. "This looks like the start of another beautiful day," she said to herself as the golden glow of her magic wrapped itself around the rose and pressed it against her muzzle.
Lost in her thoughts, imagination, and expectations, Celestia happily trotted off to the bathroom to start her morning routine: Brush her teeth, take a shower, and start a ridiculously-long battle with her mane. She hated to admit it, but regardless of how long it took to untangle her mane and iron out its kinks, she wanted and needed a little bit of time for herself before spending yet another day buried in paperwork.
She picked up her toothbrush and opened a tap and—
"Tia!"
Celestia quickly turned around, her magic somehow propelling her toothbrush hard enough to launch it into the shower cabinet. "Lu-Luna! W-what are—?"
"I took a shower before heading to sleep. And you… You look like you've seen a ghost."
"Ghost, yes… Either that or somepony scared me."
Luna giggled. "Tia, the door does say 'occupied'. At least you caught me when I was all done." She paused for a second. "Well, almost done."
"What? Oh, right, I guess I hadn't noticed."
"So I see," Luna mused. Her magic picked up a nearby towel, and she started to wipe her dripping body. "Well? Are you going to tell me who's the lucky pony?"
"Lucky pony?"
With a flick of Luna's horn, the fragile flower floated from the ground. "I believe this is yours? It's certainly not mine," Luna said with a smile. "You're acting exactly like when you met… you know who."
"I'm not! I just… Am I really?"
"You're blushing, Tia," Luna said and tapped Celestia's nose with the tip of the rose. "You've also missed a pretty big sign on the door as well. Not something you usually do. Not even this early in the morning…"
"Hush, or I'll launch you to the moon again," Celestia deadpanned.
Luna giggled. "Of course you will," she replied with a smirk. "So, who is it? Anypony I know? Mayhaps a member of the Royal Guard? Mayhaps even its captain? Tia, Cadence will—"
"It's not Shining Armor!" Celestia shot back. "At least, I don't think it's him…"
"Think? What do you mean by 'think'?"
Celestia shrugged. "Somepony is sending me letters. He usually doesn't send anything but a single rose and some writing, sometimes something that would cheer me up, sometimes a poem." She giggled. "I don't think Captain Armor can write poetry, so I'm pretty sure I'm safe there."
"Wait… Does that mean you have… a secret admirer?"
Celestia nodded. "He seems sweet, and I can't wait to meet him. It's been far too long since I've been with anypony. As a matter of fact, I… uh… actually forgot when that actually happened.
"Oh dear. I hope I hadn't forgotten everything."
"Tia…"
"If he would invite me out, what would I wear? Where would we go? I mean—"
"Tia!" Luna barked, snapping Celestia out of her rambling.
"What? Oh, sorry, I lost my head there for a little bit." Celestia smiled. "But regardless, it would be nice to go on a date after so long."
"Even if it’s possible that your admirer is a mare?"
Celestia tilted her head. "A mare?"
"You're convinced that your secret admirer is a stallion. What if it's not?"
"A… mare?"
"Tia," Luna said as she tapped the rose on her sister's muzzle. "Tia, you're a princess, you're smart, and you're very beautiful on top of it all. Don't tell me that you never thought that a mare could be interested in a pony like that."
"No, not reall—"
Whack. Before Celestia managed to finish her sentence, a soaking wet towel, now crumpled into a loose ball, hit her in the face, leaving both giggling like foals.
"Now you're just being silly. Anyway, we'll see each other in the evening," Luna said happily. "Good day."
Celestia waved her hoof, locked the door with her magic, and turned towards the shower. "I swear, Luna, one of these days you'll scare me enough that I'll launch you to the moon. Again," she muttered to herself. "Unless you deliberately want me to do so," she added. "That, or you just want me to lose all my toothbrushes. And speaking of which—"
She poked her head into the cabinet, spotting the brush immediately. However, it wasn't the only thing that caught her eye. Sitting in a corner of the tub, a slick, dark-blue, rubber replica of a stallion's erect penis waited for its next adventure. Regardless of seeing the same toy a few times before, she had hardly ever seen it after just being used.
Her nose recognized the unmistakable scent of Luna that was still lingering on it, and with the encounter of her dream still fresh on her mind, she cautiously approached the toy. With the tip of her tongue, she tasted the thick, rubbery toy, licking some of the residual fluids off of it.
To her surprise, the encounter didn't make her cringe or back away, quite the opposite. Like in her dream, she felt butterflies flutter in her stomach. However, those stemmed not of discomfort, but the combination of curiosity, excitement, and emerging lust.
Her timid licks quickly emboldened to a thorough cleaning of the entire tip. After a few moments, she stopped abruptly and jerked away from the toy. Her mind was racing as she motionlessly stared at the rubbery member. She felt the heat spreading across her muzzle, tinting it red.
"I—" She buried her face in her hoof. "She's your sister, Tia," she muttered to herself. "First the dream, then this… What next? You're going to sleep with her? Get a grip on yourself." With a swift move, she wiped her mouth and turned away.
Unlike other days when she spent ridiculous amounts of time taking care of her mane, she picked up the pace. She brushed her teeth and took a quick shower, her mind needing to get away from the bathroom. Wanting to start her workday early or perhaps visiting Ponyville for their yearly celebration, it did not matter. Anything was better than thinking how much she enjoyed her latest dreams or what she had done just minutes ago.
With one final stroke of her brush, she was finally done, her morning routine concluded. She looked at the mirror and sighed. "You're a mess, Tia. At least work will keep you distracted from what happened today. Or sleep. Or sleep at work." She giggled at the sheer thought, spun around, and headed towards her office.
It didn't take her long to focus on her work. A seemingly never-ending pile of paper that's been stacking on her desk, a pile that, for a princess, was usually nothing more than a chore, was now a distraction that she desperately needed.
With time, she drowned her thoughts in paper, enough to make her lose track of time; but as busy as she made herself, she still couldn't silence the lingering question that Luna asked: You're convinced that your secret admirer is a stallion. What if it's not?
"Pfffft," she said to herself. She lifted the rose with her magic and pressed it against her muzzle again, taking a deep breath of its sweet scent. She could feel the warmth spread across her body as the image of her mystery companion formed in her mind. A young, handsome, dark-grey stallion would pin her between his strong forelegs, and his mouth would quickly but gently glide down to her most sensitive area. She'd indulge her lover, opening her hind legs even more, allowing him to take a sip of her nectar before he'd plunge his stiff member deep inside of her.
With that imagery on her mind, she bit her lower lip and closed her eyes. Her hoof, like on autopilot, snaked between her hind legs and glided its tip over the damp slit, making her moan softly. She grinned as the pleasure of the act washed over her, however, her body wanted more. She pressed slightly harder, the tip of the hoof sliding smoothly between her folds and brushing against the erect clit.
She moaned again and pressed even harder. As her hoof started to circle around her sensitive nub, her breathing became deeper, and the massage focused on the tip of her clit. Moving her hoof faster and faster, she felt the pressure building up, until her body jolted in the ecstasy of the self-induced climax, trapping her hoof between her hind legs in the process.
Catching her breath, she slowly opened her hind legs, freeing the trapped hoof. Hesitantly, she brought the damp hoof to her muzzle and took a whiff, which resulted in her cringing and putting it away immediately. "I don't think so," she muttered to herself. "Besides, Luna's smells nicer."
She blinked when she realized what she had just said. "Tia," she reprimanded herself. "That was just a dream." Without a second thought, she scanned the room, looking for something she wasn't sure of herself, and then focused her attention on her hoof and the small puddle that had formed underneath her. "I also need to clean up."
A few minutes and a bathroom visit later, Celestia sat back behind her desk like nothing had happened. Again, she lifted the piece of parchment adorned with short writing. She took another look and giggled. "Mare, huh? What mare would be even interested in me? Silly Luna. But then again, wouldn't the same apply to stallions?" Without another thought, she folded the letter and placed it into a wooden box to join the others. As much as she was taken by the letter itself, a pile of paper in front of her reminded her of her own duties.
It didn't take long for her to lose track of time again, but soon, her concentration was interrupted by a knock on the door.
"Princess Celestia?"
"Yes?"
"Your afternoon tea, Princess."
Celestia opened the door. "Ah, thank you," she acknowledged the gesture with a bright smile. "Exactly what I need." She looked at the tray and noticed something was missing. "Hm. There is no letter today?"
"Letter?"
"A letter that I—" Celestia blinked when she realized how happy she was to receive a letter from a pony she knew nothing about, not even their name. Luna was right. Even though the letters had been there to brighten up her day, the written words of the mysterious pony had somehow managed to sneak into her heart and make her yearn for the next letter. She sighed. "Never mind. Has my sister woken up yet?"
The servant shrugged. "I think I saw her—"
Celestia nodded. "Thank you." She hastily stepped around her servant and exited her chambers.
"Princess, you forgot your tea!"
"Oh… um, I think it can wait for a little bit. Besides, I never liked scorching-hot tea."
"But—"
Celestia smiled and ran towards Luna's chamber, leaving the servant confused.
Upon arriving at Luna's room, she knocked lightly on the door adorned by a depiction of a large crescent moon. "Luna? You were right. I just realized… I'd really like to meet the pony behind the letters, and I need your help. I think I am really falling for him." She waited for a couple of seconds, but there was no reply. "Luna? Are you in there?" She knocked again, this time a little harder, but again, there was no noise from within. She hesitantly pushed the door open. "Luna?"
Instead of the dark room of a sleeping pony, Celestia was met with a bright room, its curtains opened to invite in the fading rays of the sun. It also uncovered the paper disaster that literally covered the bedroom floor. "What a mess. It looks like the room hasn’t been cleaned ever since she came back. I think I'll just—"
A piece of scribbled paper sitting on a desk caught her attention. "I know I shouldn't, but a quick peek never harmed anypony," she said to herself mischievously. "Who knows, maybe she caught herself a stallion as well." She scooted closer, faked innocence radiating from her.
Dear Princess Celestia,
"Hah, she got the letter… instead? Wait, this isn't—"
"Dear Princess Celestia, I know it hasn't been long since I started…" she repeated in a low tone, each word quieter than the last one until she couldn't hear her own voice anymore. And yet, she continued to read regardless.
...writing these letters, and I might not be well versed in many of the things you take for granted, but I am content in hoping that I managed to brighten your day morning, mayhaps perhaps even your day. As I started writing these, I just wanted to let you know that your endeavours are welcome and deeply appreciated, but as I continued to write, I realized it was something deeper, something… something I couldn't continue as an anonymous pony anymore.
I never told you this before, but you walk by me every day, and you hum that annoying song that keeps getting stuck in my ears. For so long, I've been gathering the courage to step up to you, look deeply into those gorgeous, pink eyes, and kiss you and ask you for a chance to have a cup of coffee together, but that never came to be. So I ask you, Princess Celestia, would you allow a humble nopony to ask you to join me for a cup of coffee? There's a—
Celestia's heart sank. Unable to read any further, she turned her head toward the door, only to find Luna staring silently at the ground.
"L-Luna? I— You—"
"Tia… I can explain…"
"No, no you can't," Celestia replied, her voice cracking.
Her expression told Luna everything she didn't want to know. She could tell Celestia was on the verge of tears, but she dared not take another step or say anything.
Celestia didn't wait for an answer or explanation; her horn lit up, and she disappeared, leaving Luna alone.
"T-Tia!" Luna yelped, but it was already too late. Her ears fell flat against her head. She felt terrible for what had happen, but there was nothing much she could do anymore. For a brief moment, she contemplated about what to do, before she too disappeared in a flash of dark-blue light and appeared in front of Celestia's door.
Without much effort, she gently pushed them open. The usually bright and vibrant room was now shrouded in darkness. The candles that usually remained lit were now extinguished, and she could hear soft sobbing in the vicinity of her sister's bed.
She swallowed hard. "Tia?" she asked softly, but there was no reply. "Tia, I'm sorry…”
All Luna got in response was more sobbing, making her feel even worse.
Luna took a step forward. "I… I never meant for it to go so far. It's just…" She sighed. "I noticed you have been feeling down lately… The last thing I wanted to see was you being like that, and I wanted to do something… And I did. It was wonderful to see you smile again."
She paused for a moment, and again, there was no reply.
"But something… I…" She sighed. "For the first time, I could say what I really felt about you, but… Now, I wish I hadn’t. None of this would have happened and everything would have been fine."
After a moment of pause that seemed to last forever, Luna turned toward the door. "I… I'm sorry, I really am."
Deafening silence filled the room as Celestia's sobbing stopped. "So it was you who made that dream," she said in a shaky voice.
Luna looked back. "What dream?"
"This morning. About… us."
Luna shook her head.
"Luna…"
"Tia, a long time ago, I gave you my word as a princess and as your sister, that I would not enter your dreams without your explicit permission. It’s a promise that I do not take lightly."
Celestia hung her head. "That means…"
"What have you dreamed of?"
"I… It was… it was nothing worth mentioning. Nothing more than a silly dream."
"And yet, you're worried."
"It's not important anymore, Luna," Celestia replied with a sigh. "It wasn't real. Just another frivolous dream."
Luna understood. She lowered her head again, letting her ears fall against her skull as she turned towards the door.
"Luna, wait," Celestia breathed. She stepped off the bed and slowly paced towards Luna. She paused just inches away from her sister’s muzzle, curiously and silently staring at Luna.
"Tia?"
Instead of a reply, Celestia leaned forward and pressed her lips against Luna's out of curiosity. With everything that had happened these past weeks, she felt like that finally everything had fell into place. At that moment, she felt like she was reliving her dream, and the warm and welcoming set of lips was all that mattered. She put her hoof on her sister's shoulder and pushed her muzzle further.
In the heat of the moment, Luna pushed back. Her forehooves clung around her sister's neck, and Celestia's forehooves wrapped around hers.
"Luna," Celestia whispered after their kiss broke, their muzzles still leaning on each other as they enjoyed the warmth of their breaths. "Lu, what if…"
Luna smiled faintly. "Nopony will ever know, Tia. It's just you and me." Her hoof glided down her sister's snow-white neck and pressed against her sister's chest. She could feel Celestia's heart racing, which only further fueled her own lust.
Celestia laid on her back, and let her worries and concerns go. In that very moment, it was just the two of them, two lovers enjoying each other.
Not long after, she closed her eyes as she felt another kiss land on her chest, one right between her teats, and another one— Her body shivered as the last kiss landed on the top of her still-dry slit.
Luna giggled. "Too much already? I haven't even started yet…"
"Luna, I've never been with a mare, so…"
"More the reason to relax and enjoy it. I don't bite… much…"
Celestia smiled and nodded subtly, and with it, she opened her hind legs just a little bit more, allowing her sister even easier access to her intimate parts. She couldn't help but look down just as Luna nipped her nipple and took her teat into her mouth to suckle on it, the back of the rough tongue stimulating her now-stiff nipple. If Celestia was capable of a coherent thought, she would’ve sworn that Luna mistook her teat for a flaccid penis, working her way to stiffen it.
Regardless of what Celestia was thinking, Luna did her job expertly. She spent enough hot nights with mares to know how to turn them on and eventually bring them to one of their most powerful climaxes. And she knew that she needed to take her time.
So she did.
The treatment of one teat eventually migrated to the other, and Luna’s hoof joined into the foreplay, caressing Celestia's inner thighs. She looked up when Celestia moaned and squirmed from her actions, but she didn’t let herself be fazed by that. Her focus switched back to the wet teat for a few more seconds before she let it go with a pop.
Luna took a quick glance towards her sister's nethers, where a strong, warm scent disclosed Celestia's arousal. She smiled lightly and kissed Celestia on her stomach, quickly followed by a kiss on her chest. As she nuzzled her sister's lower lip, Celestia pulled Luna towards herself, their act turning into a deep kiss.
With their muzzles still locked like two needy lovers, Luna's hoof snaked between Celestia's legs and pressed against the slippery slit.
Celestia broke their kiss and gasped.
"Luna…" she whispered, staring deep into Luna's eyes and added in a pleading tone, "Lu… Stop teasing me, please…"
Luna smiled and gently pressed her muzzle against Celestia's as a sort of affirmation. Luna planted another kiss on her sister's chest and then turned around, her intimate parts now fully exposed for Celestia's muzzle.
The plump, dark-blue nether was a sight to behold. The two strong, dark thighs were something Celestia glimpsed now and again, each time with a hint of envy. It was clear Luna wasn't as keen to taste the sugary goodness from the royal kitchen as she was. Between the thighs was a sexy, slightly-opened crevice that was clearly waiting for her attention. She could even see a tiny droplet escaping the forbidden fruit and landing on her chest. For a split second, she tried to imagine if Luna was seeing the same with hers, but the thought faded away when her sister's intoxicating aroma permeated her nostrils.
It was the same warm and arousing aroma that Luna left on her toy. Celestia cautiously leaned forward, the tip of her tongue pressed against Luna's crevice. With a gasp, her entire body stiffened as she felt Luna's warm tongue press against her slit, spreading the lips ever so slightly. Celestia closed her eyes and took in a lungful of Luna's thick scent, let her body relax, and enjoyed what Luna had in store for her.
Without much pause, Luna continued. Whether Celestia wanted to do something more with what she presented, Luna didn't know for sure, but regardless, she enjoyed what she had in front of her. A slippery organ emitted Celestia's arousal, so she knew that she did her job well, but she was quite far from being done.
Luna pushed her tongue into the small opening between the now-soaked lips and let it slip even deeper. Celestia's body stiffened and let out a tiny sigh of pleasure, but Luna wanted more. Luna wanted to drive Celestia to a climax she could never reach with a few thrusts from a stallion. Her tongue glided through the warm and wet slit, stumbling on a small, pink bud now extruding from the delicious folds.
Luna smiled and flicked the tip of her tongue against it. Celestia flinched. With another flick, Celestia flinched again. And again. As amusing as it was, Luna took the pink organ between her lips and suckled on it.
"Ohhh…"
Luna latched to Celestia's labia, her tongue quickly swishing across her sister's erect clit. As she continued to do so, she could hear Celestia's breaths deepen. Luna smirked. With a flick of her horn, she switched her position back. As much as she enjoyed being in a position like this, she was determined to see Celestia squirm and eventually watch the divine climax.
She kissed Celestia's inner thigh before she looked up, just to see Celestia looking back at her with her beautiful, pink eyes. Without breaking eye contact, Luna dove back between her sister's folds and continued playing with her clit.
It didn't take long before Celestia started to breathe heavily again, still trying hard to keep her composure. However, that was deteriorating quickly with every tap of Luna’s tongue against her clit and every shift of her sister's hooves across her inner and outer thigh. She felt a pressure building within herself, a familiar pressure she was all too eager to release. "Lu…"
Luna felt what was happening as well. Just before Celestia muttered her name, Luna dipped her tongue between her sister's warm folds, happily lapping up the moisture that manifested within the divine crevice. It was more than enough to push Celestia over the edge with a small scream, sending her hips up with a shiver and a small stream of clear liquid into Luna's eager mouth.
With a few skillful licks, Luna happily cleaned the remaining liquids off of Celestia and gave a kiss to the winking vulva, another one on Celestia's stomach, and the final one on her sister's panting mouth.
"Luna," Celestia cooed when she managed to catch her breath.
"Yes?"
"That was really wonderful. Truly something I hadn't experienced in… a very ĺong time…"
Luna smirked. "I'm glad you enjoyed it."
For a brief moment, silence fell between the ponies.
"Luna?" Celestia asked again.
"Yes?"
"What… I mean… how long did you… About me…" Celestia fell silent.
"You mean since when I felt like this about you? Since we were foals… You were the first pony to kiss me, and I… never got the chance to return it."
"Since we were… But you never said anything…"
"I tried, but all of my endeavors were fruitless. The hints I gave were not enough to catch your attention, and mayhaps it was better that way." Luna giggled. "Thinking of it, I wonder what the nobles would have said…"
Celestia smirked. "At least, I now know why I caught you staring in my general direction on several occasions… It wasn't that general, was it?"
Luna shook her head, clearly amused by the conversation. "What can I say? I had a nice view."
"Mhm." Celestia answered happily, her hoof started to caress Luna's chest, just like Luna caressed hers. "Within my dream, it was just you and me. A warm night that ended like tonight. The only thing different was that I had taken the lead.
"Which is strange. Before tonight, I never thought that I'd spend a night with a mare. Especially with… Even though…" She stroke Luna's cheek. "Lu," she whispered.
"Another round?"
Celestia smiled.
"I have an idea," Luna said. She flicked her horn, and a moment later, a rubbery strap-on appeared between her hind legs, standing erect, seemingly waiting to fill a warm and welcoming hole.
Celestia shook her head.
"What?"
"This will hardly do anything for you… I want us to enjoy this together…"
"You mean…"
Celestia nodded.
"Tia," Luna said cautiously. "That could be a very bad idea."
"It might be a little late for that," Celestia mused. "We already did something that'd make nobles faint. Besides, I took precautions, so neither of us need to worry about it." Her hoof ruffled Luna's chest again, and she nuzzled her lower lip. "Lu…"
After a moment of hesitation, Luna pressed her lips to her sister's and lit up her horn. She could feel the rubbery toy become a living part of her. It wasn't long before Celestia could feel the long, now stiff, dark-blue penis pressing against her inner thigh.
"I forgot how taxing this spell really was," Luna said, panting. "I just—" She fell silent when Celestia's mouth covered hers. A curious tongue seized the moment of surprise to play with hers, deepening the passionate kiss even further.
"My turn," Celestia breathed when their muzzles parted. It didn't take more than a little nudge for Luna to forfeit her position and lie on her back, her appendage fully erect between her legs, patiently awaiting for undivided attention from her sister. Celestia nudged it, and it shot up like a soldier on command.
"You weren't kidding."
Luna shook her head.
Celestia smirked and kissed away the droplet that appeared on the penis’s top. It carried the same scent and aroma she encountered in the bathroom the other day, only this time, Luna's newest appendage reacted to her ministrations. Her mouth gently took in the top and slowly glided down the dark-blue shaft. Just like Luna, Celestia was in no hurry either. After she reached the bottom of the shaft, she returned to its top, released it for a moment, letting the cool air lick the sensitive tip, before going back down and up again.
With a nudge against her white flanks, Celestia understood the gesture and offered her behind to Luna.
Luna smirked. It was the second time she was glaring at Celestia's awaiting crevice that desperately wanted attention as well. She gave the irresistible, pale folds a passionate kiss before her tongue snaked inside and started to explore the now familiar warm and wet interiors.
Luna wanted to take her time to enjoy her current position, but she knew full well that she did not have the luxury of time on her side this time. Her sister's ministrations had already started to take their toll; each suck, each stroke against her newest member carefully added to the already-tingly lower part of her body. She knew quite well that if Celestia kept this tempo, she would explode into Celestia's mouth very soon, leaving her sister to finish on her own.
Luna closed her eyes and let her tongue wander between the slippery folds, briefly exploring the gap, but again, she postponed more meticulous discoveries. Instead, she led the tip of her tongue even higher still, stumbling on a gem now-hidden between the tasty lips.
She flicked it, causing Celestia to moan and pause for a moment before returning back to what she was doing. It wasn't good enough. Luna gently spread her sister's legs even further and pressed her muzzle against her slit. Her tongue occupied the erect bud, flicking relentlessly against it. It wasn't long before she felt a thick liquid starting to ooze out of the slit again and ending in her mouth.
With all the enthusiasm that Luna exerted, she hadn't even noticed that the ministrations between her own legs ceased completely, leaving Celestia breathing heavily again.
"Lu… na," Celestia breathed between her pants. "W-wait, hold on."
Curiously, Luna looked up, disappointed to see her sister's rump move away from her muzzle, removing the source of heat and delight. It didn't take more than a few seconds for warmth to return, now radiating from Celestia's lips. Luna wrapped her hooves around Celestia's neck and pulled her closer in a passionate kiss.
Celestia rolled onto her back, her hind legs spread, and whispered, "I want you, Lu… inside."
Luna didn't need to be told twice. Her stiff member was just as impatient as her sister, if not more. With a quick glance towards her shaft, Luna spotted a droplet of precum forming on top of it. With a smirk, she stood up and glared at her sister. She took a step further and lowered her head, kissing the rims of the awaiting vulva, sneaking the tip of her tongue between the hungry folds, and flicking the erect clit once again.
Luna moved forward and placed another kiss on Celestia's stomach. She moved even further, gazing at the hungry, pink eyes as the thick member entered the warm and slippery crevice, far beyond the reach of her tongue.
Celestia moaned, placed her hooves on her sister's hips, and smiled faintly, inviting Luna to continue.
And Luna did so. With each thrust, Luna felt Celestia let her remaining reservations go, and with it, she could feel her muscles relax and enjoy the intimate moment between the two of them. She couldn't resist leaning forward and steal yet another kiss from her sister's mouth.
"Faster, Lu," Celestia breathed.
Luna happily obliged. She could swear Celestia's movements became more erratic as her breaths became deeper, her hind legs becoming stiffer with every thrust.
Suddenly, Celestia gasped and clung to her sister's body. "Luna…"
However, Luna had stopped listening a while ago. Her mind was set for Celestia to reach another climax, and she didn't need her sister's words to tell her she's on its verge. She felt Celestia's body cry for release, and so was hers. She increased her tempo even further, wanting to reach an orgasm at the same moment, but it was too late. She felt Celestia's body shiver, and it was all the encouragement that she needed to let go of her own reservations as well. She needed to finish. Her thrusts became shorter and faster, until her body stiffened up, and released all the pent up pressure and pleasure, and with it, a stream of cum shot deep into Celestia. And another one. And another.
Satisfied but exhausted and desperate to catch her breath, Luna collapsed onto Celestia's warm and welcoming chest. It was all that she wanted at that moment, and if she could muster a coherent thought, she couldn't think of any other pony that she'd like to see under her in that very moment.
A warm hoof pressed against her cheek, and she looked up, glancing at the beautiful, pink eyes. If she'd even have the slightest amount of energy left, she'd stretch her neck and kiss the smile on her sister's muzzle, but instead, the fur on Celestia's chest had to be good enough.
The room fell silent for a while, just the sounds of a pair of exhausted ponies trying to catch their breath.
"Luna…" Celestia started first, but her inquiry yielded no result. It took her a moment or two to realize Luna's panting had calmed down, and the deep breathing had turned into soft, yet cute, snores. She couldn't help but giggle like a foal. "What a mess," she said quietly, unsure if it was loud enough for Luna to hear, even if she was awake.

Deep into the day, Luna finally roused herself from sleep with a little help from Celestia's sun. Within a moment, Luna's eyes shot open, her mind clearly in panic mode. "I overslept!" she nearly screamed. "What— wait— why is it so—"
"Morning, Luna," Celestia chirped.
"Morning, yes," Luna replied in a groggy voice. "Why didn't you wake me up to lower the moon? It's my duty."
Celestia smirked. "Exhausted princess trying to control a celestial body. Yes, that's always a good idea. We should do that more often."
Luna groaned. "Once. Just once. You won't let me forget it, will you?"
"Of course not," Celestia mused. "Isn't that what big sisters are for?" With that, her tone changed, and her smile waned from her muzzle. "Luna, about last night…"
With a shimmer in her eyes, Luna hung her head. She felt like she had swallowed a hoofful of sawdust. "I… I understand. You don't want us to—"
"No, Luna," Celestia said sternly. "It's just… you tricked me, and it's going to take some time until I come to terms with that. Even if it ended like it did, I still need some time to process everything. But until then…"
"Until then?"
"Until then, you're still my little sister, a sister whom I love very much, and nothing will ever change that. I just wish that you'd tell me what you said as… you."
Luna hung her head again. "I… I understand."
"I'm glad," Celestia replied cheerfully. "And I hope we can do this again sometime. It was really something I think we both needed."
Luna smiled. "I would like that."
