Luna's first attempt to raise the moon leads to the unwitting birth of Molestia.

Luna is tired of waiting for her opportunity to lift the moon into the night sky, and jumps on the first chance she gets. But trying to lift something so big puts her in a compromising position, one that the watchful eye of her older sister is keen to notice.

Chapter 1

Raise the Moon

Luna trotted out onto a balcony, looking up with an excited grin as Celestia touched down on the marble surface herself, her head continuing downward into a deep bow as she steered the sun gently below the horizon. The sky faded from blazing shades of orange and red to indigo and royal purple. The light continued to shift as the sun dipped further beyond the skyline, the sky fading to a uniform shade of deep blue. Celestia remained in place for a moment, seeming as though she might kiss the floor she knelt at, then opened her eyes and lifted her head with a tranquil grin.

“That was so pretty...” Luna mused in wonder, drawing a surprised twitch from her sister.

“Oh, Luna,” she smiled back at the little alicorn as she wandered over to her side. “Were you watching me?” she asked with a joking air of suspicion. “That’s not polite, you know; watching someone without permission.”

Luna fiddled a hoof and looked away for a moment with a faint purple blush, muttering an apology, then looked back up at Celestia, her blue cheeks turning orchid.

“Hey Tia?” she asked bashfully, “Um...d’you think...I could lift the moon tonight?”

Celestia’s smile broadened. “You think you’re ready?” she asked, leaning down to nudge Luna’s side.

Luna giggled and pushed her elbow away. “I can do it,” she chuckled. Then looked at the horizon, her smile faltering only slightly. “I think...”

Celestia caught on to her sister’s insecurity and followed her gaze to the horizon. “...I could help, if you want.”

Luna’s gaze remained fixed on the edge of the world a moment longer before she shook herself and looked up. “Huh?”

“If you need help...” Celestia trailed off.

“I can do it!” Luna protested, stepping forward. She looked forward, gulping quietly, then set her jaw. ‘I can do it...’

“Alright then,” Celestia conceded, taking a step or two back. “But if you do, I’ll be right here.”

Luna looked back at her and nodded thankfully, then turned her focus to the horizon. She took a deep breath, then spread her legs out slightly and lowered her head, pouring magic into her horn in preparation to drag the moon up from its hiding place. Celestia smirked at her obviously inexperienced stance, shaking her head slightly, then flinched as Luna flexed the muscles along her back and inadvertently lifted her tail into the air.

“Oh, um...” Celestia lifted a hoof to her mouth, her face reddening slightly. “Luna, don’t...could you stand up for a moment?” Luna straightened up and looked over her shoulder with a confused frown as Celestia walked back up beside her. “You need to lower your whole body when you kneel, you see,” Celestia explained, showing her the proper position. “What you were doing is...not exactly very.....modest.”

Luna titled her head, her face a picture of innocent confusion. “What does that mean?”

Celestia pursed her lips, trying to come up with a discreet explanation. “Well...When you um...a filly, or a mare, rather, usually only gets in a stance like that when she wants...It’s just not proper,” she concluded, now flustered.

“Why not?” Luna asked with a scowl.

Celestia opened her mouth, searching for the right words, then sighed.

“Well, it...exposes you to anypony who’s standing behind you,” Celestia said, gesticulating on a circle with a hoof. “It’s not something you do around other ponies. You’ll understand it better when you’re older, just...kneel like I showed you.”

Luna nodded slowly, part of her sister’s vague explanation making sense, and looked down with a blush. “Sorry, Tia,” she murmured.

Celestia nodded, glad to have gotten the point of her message across, and backed up again to let Luna concentrate. She heard a whisper in the back of her mind, and paused mid-step to look behind herself. She frowned, confused by the voice she thought she’d heard, but shrugged the event off and turned back to Luna.

Luna looked out a the horizon again and carefully set herself into a kneeling position, lowering her head, and flooded her horn with magic. She reached out with her mind, telekinetically feeling around the hidden side of the sky for the moon, and smiled to herself as she felt it brush against her psychic fingers and latched onto it. She set her hooves on the ground and started to stand, but jerked to a stop as the weight of the moon suddenly made itself known. Luna gasped, opening her eyes and losing her concentration, and the bond between her and the moon was lost. Celestia took a half-step closer.

“Are you alright?” she asked quickly, worried by the way she had flinched while trying to stand.

“I-I’m okay,” Luna said with a hint of embarrassment. “I just...didn’t think it’d be that heavy.”

Celestia let out a quiet sigh. “Oh...Yes, it is quite heavy,” she chuckled. “Do you want a little help?”

Luna’s ear twitched, her mind rolling the suggestion over, but she stood her ground. “I can do it,” she said determinately.

Celestia nodded and stepped back, leaving Luna to her previous occupation. The blue filly smiled confidently to her sister, then gulped quietly as she turned her focus back to the sky line. She took a deep breath and puffed out her chest, sizing up her goal, then lowered herself back into the kneeling position Celestia had showed her and extended her magic beyond the horizon once again. Her mind brushed against the rough surface of her target and she latched on, grabbing hold of it with her magic and pulling the line taut. She opened one eye, smiling at having made a stable connection, then closed it again and focused on her goal.

Luna tugged at the cord she’d made between her and the cosmic mass, testing its strength, then began to pull. The heavenly body pulled back, straining Luna’s force of will, and the bond between them weakened considerably before Luna stopped pulling to adjust its strength. She gave it another steady pull, but was met with the same problem and stopped again with a look of annoyance. Evidently she was going to have to work on keeping the connection and lifting the moon at the same time. She sighed, mentally preparing herself for the task, then closed her eyes and once again began to pull.

Celestia watched closely, keeping an eye out for signs that Luna would need her help. From her starts and stops and brief pause, she wagered Luna had already realized she needed to multitask to get the job done, but technique wasn’t her main concern. The method was relatively simple, just an oversized version of the telekinesis a unicorn uses on a daily basis. What worried her was the fact that it was so oversized. Despite her confidence, Celestia knew Luna might not be able to lift the massive object on her own, and was standing by to give it a little push from below to get her going.

Discreetly, of course. She didn’t want Luna thinking she’d never be able to do it on her own. Or hurt her pride.

Luna’s body started to rise, snapping Celestia out of her thoughts, and the pale glow of the moon began to crest the horizon like the corona of the sun. Celestia beamed at the light, turning her focus to Luna, and felt her smile fade. Luna’s body was shaking, straining under the weight of the object she was attempting to lift. Celestia’s brief moment of relief ended and she returned to watching for signs of fatigue. This was the hardest part of the ordeal after all; breaking the Horizon Line.

In Equestria, there has long since been a set of rules put in place to govern the movements of the sky. Every so often, there must be a storm organized by the pegasi. When the seasons change, the residents of Cloudsdale are called upon to deliver the necessary elements of the season to the weather control centers of each individual town, city, or province. And, amongst the royals, the duties of maintaining day and night in sequence are handled. What many don’t know about the latter, however, is that the rules that govern the movements of sun and moon are enforced by a magic more ancient than that of the royals who enact them.

There is a force, a barrier, that lies just below the horizon, called “the Horizon Line” (a sort of joke name given to it by a king of generations past). The line cannot be seen, only felt, and only by those who attempt to move one of the two heavenly bodies through it. It determines day and night, governing the passage of days in the world of ponies. When either the sun or the moon is up above, the barrier will prevent the other from crossing into the sky. When one goes down, it registers in the Line that the other may rise, and the object that just set is barred from rising again until its counterpart has passed through after its turn in the air.

Obviously the barrier works differently during periods of lunar or solar eclipse, but the mechanics have always been considered “too finicky” for anyone to give it any serious thought.

Celestia set her gaze on her sister, glancing occasionally at the horizon to check her progress. Cleared for launch or not, the Line was still an active barrier. It prevented any but the most magically powerful (namely the royals) from being able to pass objects through it. Celestia had taken only one try to get through the Line the first time, but it had only just allowed her through. Luna was much younger than she at her first attempt, and less magically skilled as well. Celestia nervously bit her lower lip, worried that Luna may need more time before raising the moon on her own.

Luna lifted herself out of her kneeling stance, groaning as she tried to lift her head before it sank slightly and she shot out her front legs to keep herself upright. Celestia almost said something, but kept her mouth closed. Luna needed to completely focused on the task at hand if she wanted to succeed. Luna tried again to raise her head, the muscles down her back and sides straining to lift her up, and she subconsciously adjusted her stance to ease the tension on her muscles, lowering the front of her body and lifting her rear.

Celestia felt a tinge of adrenaline and embarrassment as Luna shuffled her hind legs apart slightly, trying to keep her stance strong, but kept her mouth shut for fear of breaking her concentration. Luna began to lift her head, pushing up with her front legs, and inadvertently flexed the muscles around her tail. Celestia gave a nervous glance behind herself to be sure they were alone, for Luna’s sake, and turned back to her. She watched for another few seconds as Luna continued to flex her muscles and further expose herself before she took a small step closer and lifted a hoof, opening her mouth to say something, but suddenly stopped.

Celestia remained frozen in place, staring ahead at Luna’s rump, the tip of her tongue placed against the roof of her mouth to say her sister’s name...but she suddenly found she couldn’t move. There was something...strange about the situation. Some odd, ineffable feeling she got from the position she was in.

And there was something too about Luna that the princess couldn’t put her hoof on. Her eyes ran across her sister’s back, down her sides, around her exposed rear, and down to her shaking knees. Something about the position was...hypnotic. Celestia felt mesmerized. It was a frightening thought, and an unfamiliar feeling, but ones she couldn’t seem to push out of her mind.

Celestia remained frozen a moment more, then let her tongue lie flat in her mouth. It was a small movement, but it broke her paralysis and allowed for more.

She stepped closer, her eyes now glued to Luna’s rump, and slowed her cautious pace as she neared. Her skin felt strange, like it was crawling, and her entire body seemed to be getting warmer. She blinked and glanced down, noticing that her lower jaw was beginning to jitter, and rolled her jaw and clenched her teeth for a second to stop it before looking back to Luna and taking a final half-step toward her. Celestia lifted a hoof off the ground, keeping it an inch from the marble floor, then quickly brought it up to her mouth. Luna’s continued effort was beginning to put a strain on her body, a very thin film of sweat pushing its way through her deep blue coat and making her twinkle like the night sky in the dim light of the night. Celestia’s jaw started to twitch again and she wiped her mouth very distractedly as she realized she’d begun to drool a little.

‘What is this?’ Celestia asked herself inwardly. ‘What...why am I feeling like this? It’s so...bizarre, this...heat.’ Celestia shifted her hind legs as the mentioned heat began to intensify, Luna’s shifting her weight causing her little exposed rear to sway slightly in front of Celestia. ‘Oh, but...she...looks so...’ Celestia covered her mouth and quietly slurped up the saliva that was almost pouring out of her now, her pupils contracting into tiny black dots. ‘...soft...’

Celestia moved the hoof away from her face, holding in the air between them, then hesitantly brought it closer to Luna’s flank. She stopped, bringing it back to her chest, then shifted awkwardly as the heat in her blood surged at another little bob of Luna’s plump rump.

‘I want to...touch it...’ Celestia thought, folding her bottom lip into her mouth in an attempt to keep the drool from spilling down her chin.

‘Breathe...breathe...remember what Tia taught you,’ Luna coached herself, sending more magic into the tether as part of it began to wear thin. ‘You can do this,’ she thought with a smile. ‘You’re almost halfway through the Line. Just keep go—AH!!”

Luna jumped forward, completely severing her connection to the moon, and spun around. Celestia yelped as well, surprised by her reaction, and quickly covered her mouth. They stared at each other, shocked and confused, before Luna winced and reached a hoof back to rub her flank where Celestia had struck it.

“What was that for?” Luna asked angrily. “Oww, Tiaaa. That stings...”

“...I...” Celestia started, uncovering her mouth. “Um...there was a bug on you,” she said quickly, regretting the excuse immediately.

Luna frowned. “So?”

Celestia looked around quickly. “...It was a spider.”

Luna stopped rubbing her flank, staring at her sister with annoyed confusion. “...So?”

Celestia furrowed her brow, her mental state keeping her from thinking as quickly as she otherwise would have. “...They scare me.”

Luna held Celestia’s gaze a moment more before looking back at her flank (Celestia turning her head and questioningly repeating the phrase under her breath while Luna was distracted). She moved her hoof away, seeing that there wasn’t any kind of mark left by Celestia’s hard spank, then turned a glare back to her sister.

“Next time just tell me if there’s a bug. You could have made me drop—“ Luna gasped and spun around, shooting an arm of magic at the sky line. She blinked as her magic connected with the moon once again, surprised to find it exactly where she’d left it. Evidently the Horizon Line had caught it to stop the night from ending quickly, or maybe it was just stuck; whatever the reason, Luna was relieved to not need to pull it all the way back from the starting point. She let out a sigh and looked back at Celestia, still annoyed but less so than before. “Don’t hit me again, Tia, that really hurt,” she pouted.

“I’m sorry,” Celestia said quietly. “I don’t really know what came over me...”

“It’s okay,” Luna said, looking back at the horizon. “...Here I go again...”

Luna bent her knees slightly and shifted her stance to near what it had been before, then tightened her hold on the moon and thickened the magic she would use to lift it before starting to pull again. The brief break from her effort had given her a moment to relax her stressed muscles and catch her breath, which she supposed she was thankful for, but the dull pain in her flank was still a bit of a distraction. She soon found herself straining against the moon’s weight once again and moved her body to accommodate the stress accordingly, spreading her feet out and lowering the front of her body to take some of the pressure off of her neck. Celestia saw the signs coming and watched as long as she could, but when Luna began to flex the muscles around her tail she quickly turned her focus to the sky.

‘What’s wrong with me?’ she questioned a random point above her head. ‘Why did I do that to her? I’ve never felt like this before...’ Her eyes drifted down to the pale white glow on the horizon and her thoughts were focused on the time of night. It was getting late, and the moon had yet to even take to the sky. She looked down at Luna before quickly turning her gaze back to the sky, her face glowing red. ‘Oh my...’

Luna let out a quiet grunt as she shifted her muscles, sweat once again coating her body as she continued to press her muscles beyond any output they’d ever given before. Her lean muscles slid under her skin as they pulled taut and pressed outward, outlining just how much muscle there was. Had she been human, she would no doubt be at par with a long time professional athlete in build. She let out a breath in exasperation, then held her breath and pushed harder, straining to keep the moon moving through the invisible barrier beyond her line of sight. After a moment, she let the breath out, gasping for air, then took another deep breath and continued to push from below and pull from above the huge rock in her clutches.

Celestia kept her eyes focused on a spot in the sky, not looking at anything in particular, but glanced at the horizon to ensure progress was being made. The very edge of the massive white ball had just crested the horizon, the sight bringing a hopeful smile to Celestia’s face, and she looked to Luna to encourage her before the sight of the flexing alicorn made her quickly turn her focus away once again, a surge of heat pumping through her body with her blood and a flutter pulsing up through her stomach.

‘Just don’t look at her,’ Celestia ordered herself. ‘Whatever this is, just let it pass and keep your focus elsewhere. Take a deep breath, nice and slow, and just...ju...mmmm...’

Celestia closed her eyes and took a deep breath of the air around her, lifting her nose toward the sky and shivering as a strange smell filled her nostrils.

‘Oh my...what is tha...oh, it’s...’ She took a deep, long breath through her nose and let it out of her mouth with a shudder, her eyelids fluttering as she did. ‘Huahhh...sweet mercy, that’s good...’

She took a quick whiff of the air, sniffing out the smell with her eyes closed, and dipped and turned her head as she attempted to follow it to its source. She took a deep breath, letting out an excited sigh, and opened her eyes with a start as she realized what she was staring at.

Luna was inches away from her, her legs spread and tail raised, and her back arched as she struggled beneath the weight of the moon. Celestia stared in amazement, dumbstruck as to how she could have followed the enticing smell to such a place, but found, for the life of her, that she could pull away.

‘What am I doing??’ she thought in a panic. ‘Wha, REALLY, what in the HAY am I doing??’ She frowned, trying to fight the spell she seemed to be coming under, then found another question in her mind. ‘...Why didn’t I smell this before?’ Celestia shook herself, trying to push the thought out of her mind, but it remained. ‘Why now? Shouldn’t I have smelled it before? Has this smell always been there? This certainly has. Am I just unobservant?’

Celestia winced, trying still to pull herself away from those thoughts and that place, but the more of its aroma she breathed in, the more muddled and conflicting her thoughts became.

‘How could I never have noticed? IT’S SO OBVIOUS!! AM I CRAZY? I’m not crazy, am I? Oh, look at me...I’m three inches away from my little sister’s...crater arguing with myself about not noticing how it smells. I’ve really lost it, haven’t I?’ the princess wailed inwardly, disgusted with herself. She opened her eyes, reasserting her location to herself, and noticed something that disturbed her, not for its occurrence, but for the simple fact that she noticed.

‘...Her...her little hole...’ Celestia thought, suddenly mystified, ‘...Oh my...’

Celestia’s face moved indistinguishably closer, her eyes focusing intently on Luna’s “crater”. The opening twitched slightly as Luna let out a grunt and shifted her muscles, making a surge of heat run down the front of Celestia's body. She watched, hypnotized, as it opened slightly and closed in rhythm with her sister’s breathing, and soon her pupils began to constrict again, veins in her eyes suddenly flooding with blood and reddening her corneas.

‘Oh my my my...’ Celestia mused, her teeth starting to jitter quietly. She took a breath, a thin form of sweat starting to form on her face, then closed her eyes and breathed long and deep, sniffing Luna’s private flesh with a greedy lack of restraint. Her outward breath was ragged and hot, moisture from her saliva condensing on Luna’s rump along with the sweat and making her flinch, the opening to her crater percolating at the sudden brush of warmth.

“Tia?” Luna asked, not looking back, “What was that?”

Celestia blinked, almost seeming surprised by the fact that Luna could talk, and straightened up slightly, her eyes still focused down below.

“What was what?”

Luna opened her eyes for a second, looking up at the horizon to see that almost a third of the moon had risen above the horizon, then redoubled her efforts. “Uh...never mind.”

Celestia’s eyes stayed focused on Luna’s nether region, her blood boiling as Luna’s increased efforts spread her open slightly and her muscular spasms made her little hole open and close. The once few beads of drool now trickled down her chin in a constant stream and her teeth chattered together as quietly as she could keep them.

It was unbearable. The heat, the smell, the opportunity; she had to do something, something, or she feared the stress of her craving might overload her senses and drive her mad (though, in truth, they may as well already have).

‘I-I...Luna...’ she managed to think through the haze of lust and irritation. ‘It’s so...pretty...cutie little booty....hah...’ She lowered her face again, drinking in Luna’s sweaty scent like a ravenous animal before pressing her nose almost against her lips and taking a deep, greedy sniff, then turning her head and letting out a ragged breath, her knees trembling beneath the weight of her self-sickening desire. She opened her eyes, turning them back to Luna’s privates, then brought her head into alignment with them as well, her tongue snaking out of her mouth and sliding across her drenched lips.

‘Oh Luna. You look...so...delicious...’

Luna pushed hard against the marble floor beneath her, the muscles in her shoulders bulging as she straightened her arms and arched her back. She opened one eye, her heart lifting as she saw the moon visibly rising above the skyline, and flexed every muscle in her body as she attempted to jerk it free of the Line in one go.

‘I can do this! I really can do it!’ she squealed inwardly. ‘Okay. One...Two...ThreeeeaaaAAAAAHH!!”

Luna whipped her head around, her eyes bulging, then quickly looked back at the horizon as she felt the moon start to plummet. She quickly regained her grip on it, bringing it to a halt, then turned her head back again, staring in shock at her older sister. Celestia stared back at her, her beady eyes opened wide. They remained frozen, neither knowing what to say or do, but Celestia’s instinct quickly overtook her confusion and she closed her eyes and dragged her tongue upward along Luna’s lips, making her seize up and almost drop the moon again.

“Tia! What are you doing??” Luna protested, shooting a glance back at the object in her grasp. “Stop, that feels really weird!”

Celestia lifted her muzzle from Luna’s muff, a long strand of sticky pony juice hanging from her chin, and licked her lips with a long, excited sigh. She locked eyes with Luna again, her head tilted to magnify the lustful gaze she shot at her, then started to lower her head again.

“Raise the moon, Luna,” she said softly, sending a chill up her sister’s spine.

“T-Tia, I...no, don’t, please.”

“Raise the moon...”

Celestia held eye contact with her sister for another moment before closing her eyes and burying her snout in the soft, pink flesh before her, shooting her tongue into the opening and moaning as the muscles around it clamped down around her.

“AH!! TIA, NO!”

The muscles around Luna’s rear began to spasm, unfamiliar with the sensation she was being assaulted with and unsure of how to react. Her legs trembled, her eyes clamping shut, and she would have jumped away had the moon’s weight not reasserted itself. She opened her eyes and looked despairingly at the great ball of white that loomed over the horizon and threatened to drop should she lose her focus for too long. Evidently it had just gotten stuck in the Line previously, as it was beginning to slip out of her grasp the more distracted she became. Luna moaned in annoyance and confusion, trying to strengthen the tether to at least keep the moon from slipping out of her hands, then looked back at Celestia.

“Tia...what are you doing?” she asked weakly, her face flooding with color. “That’s...mnnn, stooop.”

Celestia couldn’t hear her. She could hardly hear anything over the rush of blood in her own ears. Her body was hot, burning, and she was soothing the raging urge inside herself the only way she thought she could.

It was incredible. The taste was even better than the smell, and the texture was nothing short of maddening. So soft...so smooth...so juicy...It was enough to make the pink maned alicorn lose herself. She let out a long moan through her nose and pressed further, opening her mouth wide and pressing her tongue as far into Luna’s sticky, wet canal as it could go. The cobalt coated alicorn rolled her head, moaning with confliction and irritation at the heat that was beginning to spread upward along her belly from the point of contact with her probing sister. Her head jerked, the moon starting to slip as she lost focus on it, and her upper body was forced downward as she regained her grip on it and brought it to a halt, opening her further to Celestia’s prodding tongue. Celestia noticed the shift and took the opportunity to push deeper, straining her tongue to reach in as far as the flexible skin pressed against her muzzle would allow, until the tip was tickling at Luna’s cervix. Luna’s muscles clamped down on Celestia’s snout, making her pull her head back some to be able to breath, but she quickly buried her nose in Luna’s muff once she’d gotten a breath of air.

Luna squirmed, struggling to keep the moon steady while she tried to fight off Celestia’s ravenous tongue by wiggling her rump and shifting her legs, both of which only seemed to egg the starving animal on. She cracked an eye at the horizon, at the mockingly bright moon, then took a deep breath and stamped a hoof on the marble floor, starting to push again. Celestia had told her to raise the moon. Maybe if she did, she would stop whatever it was she was doing. Maybe it was a test, something every pony had to go through their first time. Luna clung to that hopeful thought as she began to push off the ground and lift herself back into a standing position, the massive lunar object following suit at a depressingly slow pace.

Celestia moaned as Luna’s increased efforts made the muscles inside her seize up, tightening the already vice-like canal of her supple pony hole. Her tongue was squished by her insides, her juices being pushed out by the lack of space within, and eventually Celestia had to pull her tongue out for fear of it getting stuck inside. She lapped greedily at the sweet fluids that dribbled down her chin, and then those that trickled down Luna’s haunches. She let out a hot, humid breath, the thick haze in her mind making her sluggish even in movement, and slowly blinked her beady, bloodshot eyes. Luna was shaking, both with the effort of trying to lift the moon and the unfamiliar sensation Celestia had thrust upon her. The sight of her quivering body, her legs dripping with her sweet, sticky juices, the muscles along her body clearly visible through her sparkling blue coat; Celestia shivered as a new wave of white hot lust coursed through her body.

‘That’s not enough,’ she moaned inwardly, lifting a hoof to Luna’s flank and rubbing it in a slow, calculated circle. ‘More...Give me more, dear, beautiful sister.’

‘Okay, rubbing. Rubbing’s not so bad,’ Luna told herself, trying to stay positive. ‘Rubbing’s...kinda nice...FOCUS! Just keep the moon going. She’ll stop once the moon is up. Or...I don’t know, maybe I can help her once I’ve got my hooves free? Oh dear, what do I do? Why is she...’ Luna blinked, wanting to look over her shoulder, but kept her focus ahead of her. ‘...Why did she stop?’

Spasms shot up Luna’s spine as Celestia’s body gently descended upon her in a rolling wave of motion, her haunches pressed up tight against her rear, her tongue sliding up her back as her face slid upward toward her neck. Luna kept on her feet through sheer force of will and locked her knees as Celestia came to a stop over top of her, pushing her tongue out as far as it would reach and wrapping it around the tip of Luna’s left ear. Luna whimpered quietly, terrified of what Celestia might be planning to do from this new position, and felt though didn’t exactly notice that Celestia’s body was almost as hot and sweaty as her own, despite her inactivity in comparison. Celestia moaned as their bodies came into contact, the heat from them both diffusing through their skins into one another, and subconsciously rubbed her stomach against Luna’s back, enjoying the feeling of her sweat coated body sliding beneath her own. Luna swayed for a moment, almost seeming as though she’d fall, but shot out her legs and kept herself upright.

“Tia...you’re really heavy...” she said weakly, her knees shaking under the weight of both her sister and the moon. “Please...can you get off of me?”

“I’ve got a better idea,” Celestia whispered hotly in her ear, making it flick out of reflex and Luna let out another whimper.

Celestia lowered her head and angled her horn until it was beside Luna’s, then slowly ran it up its length, pushing magic into it as she did. Luna gasped as her sister’s horn became hot, the air around their connected shafts growing electrified. She felt something else grab hold of the moon, presumably Celestia, and the weight was instantly cut in half. Luna let out another gasp as huge amounts of stress were taken off of her body, her limbs suddenly feeling much lighter than before. Her reprieve was short lived, however, as Celestia began to grind against her, stroking her slender horn with her own, and a new kind of strain began to overtake her.

“Is that better, little sister?” Celestia asked in a sweet yet disheveled voice.

“I...Tia, why are you doing this?” Luna asked, trying to buck Celestia off with weak bumps of her rump.

“Mmm, keep that up,” Celestia nearly hissed in Luna’s ear, adjusting her movement to fit the rhythm of Luna’s bumps. “Ohhh....you’re good at this,” she giggled mischievously.

Luna quickly stopped, drawing a disappointed moan from Celestia, but her grinding and stroking was unabated. Luna returned to her previous strategy of do what Tia says and see if she stops and refocused her energy on lifting the now much lighter moon, feeling it respond immediately to her pull. The massive object began to rise quickly, at least compared to before, and soon more than half of it had broken through the Line.

But the harder Luna pressed, the more her magic intertwined with Celestia’s, and the more the hot, staticy sensation began to spread outward from her horn and down into her body. Celestia sneered at her panting sister and flattened her tongue against the back of her neck, dragging it upward in a slow, forceful arc around the side of her head. Their horns broke contact for a brief moment, and as they did, adrenaline surged into Luna’s blood as the thought of the moon dropping passed through her clouding mind. But then their hors relocked, and the moment was gone, the rush of epinephrine still tickling Luna’s extremities.

The moon marched on, creeping out from behind the curvature of the world, and Luna’s fears began to fade as the Line slid down around it, almost to the very bottom tip of the pale sphere. Luna’s heart swelled, a faint hope pushing through the heat and haze and prompting her to push harder and end the experience at last.

But something snagged. Luna flinched, suddenly unable to move the moon. Her eyes shot open as she felt the extra upward lift suddenly reverse and hold the moon in place. She whipped her head around, about to question what Celestia was doing, and found herself eye to eye with...somepony who was most certainly not her beloved older sister.

“Don’t be such a party pooper,” the wild eyed pony whispered seductively. “It doesn’t have to end yet, right?”

Luna’s heart sank, her eyes opening wide, and she started to protest but was cut off by a forceful kiss from whatever creature it was inhabiting her sister’s body. A long tongue forced its way into her mouth and wrapped itself around her own, tugging it back into Celestia’s before sliding along the bridge back into her own. Luna let out a muffled yelp, trying to disengage herself from her sister’s body, but a sudden pulse of energy from their connected horns sent a wave of disorienting heat down her spine, frying her nerves and making her watering eyes roll back into her head. Celestia closed her eyes, probing her sister’s mouth in a rhythm that allowed her to systematically stroke her horn with her own, her hips still grinding against Luna’s round, succulent rump. The blue pony had been reduced to little more than a puppet now, so overwhelmed was she by the situation and the unfamiliar and overpowering sensations it brought. She was powerless to resist the forceful grinding and kissing and stroking the ravenous white alicorn thrust upon her, and her lack of resistance only served to further push her into helpless blankness, making her a living doll to be done with as Celestia pleased.

Her body, however, was not so unresponsive. Despite herself, Luna’s trembling body was growing hot, and her legs began to move of their own accord, matching their motions with Celestia’s grinding in a circular, counter active motion. Her head began to bob slightly, synchronizing with the stroking movements of Celestia’s horn, and her own length of spiraled bone began to glow with a magic that, were she conscious, she would have no idea how to produce.

Their embrace continued; each moving in unison with the other, each losing themselves more by the minute; for several minutes. The air became charged with magic, ozone permeating the night as the electrified energies from their horns ionized the surrounding atmosphere. There were no words, only sparse gasps and moans and sighs of an intoxicated sort of pleasure. In a moment however, all motion came to a halt. A bright light erupted from the two interlocked horns, streams of liquid fire bursting out from both the tips of their horns and the spaces between their haunches. Celestia lost her downward grip on the moon as she came, leaving Luna’s tenuous grasp on the stellar sphere unopposed, and the great ball was sent hurling upward into the night sky. It slowed after a moment, crawling to a stop at the center of the night sky, and rained down a vibrant silver light over the collapsed ponies down below.

The princesses lay on the marble balcony, interlocked even in their fallen state, and panting heavily. Both their coats were drenched with beads of sweat that glittered in the night light, a slowly spreading pool of shimmering fluid spreading from their still touching bodies and serving as a testament of the events of the evening. In minutes, they were asleep, drained in every sense of the word and exhausted to the point of near catatonic sleep.

The next morning was a blur. Celestia shifted the positions of sun and moon on autopilot, still not fully conscious of the world. Luna awoke sore and achy, but otherwise unaffected by the strain she had been subjected to. Neither could remember the night clearly, all that stood out being Luna’s successful attempt to lift the moon on her own. Though a success it had clearly been however, Luna made it clear that she was too sore and tired to try and do it again that night, and likely the night after.

But it wouldn’t be long before she asked to try again.
