Lunar Eclipse

Luna blinked.

To her confusion, she found herself in the middle of a dark forest. Black, vague figures of large, ominous trees stood silently around her. Their dense foliage almost completely blocked out the view above, only allowing a tiny glimpse of the… purple night sky? Her moon was nowhere to be seen, inducing an uneasy feeling inside her. The uncomfortable tightness sensation around her entire body only added to that anxiety.

Slowly, her eyes got used to the darkness. Blurry images began to come into distinct yet warped shapes. And the first thing she realized stroke fear and confusion in her heart.

She was being suspended in midair by more than a dozen strange black vines wrapping around her legs and chest. They tilted her slightly on her back, causing her body to expose itself in quite an undignified manner. Her wings were also tied up and pulled apart by several other vines, fully extended out behind her. They did not pull like rope, but rather hardening like wood around her limbs, allowing her body to rest comfortably without pain but still rendering it completely immobilized. Another vines coiling around her cheeks back to behind her ears, preventing her head from turning freely.

What are these things? How did they get me?

She squirmed and pulled against the vines restraining her, but they held firm. She yanked her body again, much stronger this time, only to feel a stabbing pain when one of her wing bent in an uncomfortable angle from her body as it was tied in place.

Aware that breaking out with physical force was not feasible, she lighted up her horn, casting a teleportation spell. A familiar pop reached her ears. She blinked, and found herself still in the very same place. Only, she noticed, that she could not feel her crown on her head anymore. Grinding her teeth, she cast the spell again, and this time, her shoes and chest piece disappeared, while her body stayed where it was, within the bondage of the creepers.

Dumbfounded and somewhat undignified for stripping herself naked, she looked up to her horn, and saw it was covered in some kind of glowing blue dust. A quick glance around later let her discover dozens of small blue clumps of hair growing out of the vines’ stems, filling the air with ominous blue glows and the very same dust.

Is this dust messing with my magic? I need to try more simple spells. Maybe a straightforward magic blast can cut off these vines without being derai...

Before she could complete her thought, however, another vine with a hollow tip suddenly lunged forward and latched onto her horn. A warm and moist sucking feeling immediately washed over her mind. Luna let out a choking gasp.

“GAH…? Wha…? No…”

The light on her horn fizzled out. Magic started to course through her veins, along her spine, up her neck and out of her horn in an agonizingly stimulating sensation, sending shiver all over her body. Desperately, she squirmed, trying to break out with physical strength again. However, the vines stood firm, and Luna could not move a limb even as her body twitched and jerked involuntarily against her bondage.

“Ah… Ah… Gah… Hah…”

Moans began to escape Luna’s throat against her will. The tingles of magic being sucked out pinched at her every muscle, clouded her mind and ignited a burning heat deep inside her groin. Her breath became labored. Her mouth hang open. A trickle of saliva slipped out of the corner of her lips without her noticing.

Suddenly realizing what she was doing, she slammed her jaw shut and ground her teeth angrily. What was she doing? She was a proud princess of Equestria! She would never be able to face Celestia again if she lost herself to these vile creatures. She shook her head violently to wake herself from the stimulation - or she tried to. The vines pressing against her cheek did not allow her body any movement.

The creepers did not give the Princess time to regain her composure though. There was something ruffling in the corner of her eyes. Turning her glance, Luna saw another vine had just creeped up to her cheek and brushed against her face. The head of the vine ended in a big flower bud made up by three dark green petals, slightly parted at the tip. It nuzzled her throat, slowly moving up to her chin, then coiled backward to press the tip of the bud against her mouth.

A sticky, thick liquid trickled on her lips. Luna immediately pressed them tight, trying her best to not letting any in her mouth. The vine pulled back a little, seemingly dejected, a string of the sticky fluid stretched out between Luna’s lips and the petals. She threw a razor sharp glare at the bud as if trying to cut it into pieces with her eyes, while defiantly holding her mouth shut. The vine seemed to recoil a bit. Then suddenly, the large petals unfolded, revealing a sickening sight to Luna’s horrified eyes. Protruding out in the middle of the petals was a bright red… thing that looked half like a giant flower pistil, half like an elephant trunk. The pink inner side of each petals was adorned with dozens of small wiggling tentacles, pulling with them strings of gluey fluid that stick to the side of the “pistil”.

Luna could only stare in terror as the vine inched forward and pressed the sickly wet “pistil” on her muzzle again. With all her might, she tightened her lips even more, praying to the moon for the strength to resist this creature. Unable to find the entry, the flower pulled back once again, looking agitated. Luna kept staring defiantly at it.

Then, the titillating sensation of magic being sucked from her horn suddenly intensified, causing Luna’s body to jump, or as close to jumping as it could against the restraining vines. The torrents of magic surged through her body and washed through her brain before being pulled out of her. Her eyes rolled upward, unfocused as tears started to swell up. Her face muscles twitched and strained involuntarily, slowly pulling her mouth open against her will.

“Gaaaaah…” was all Luna could mutter as her lips gradually parted. As soon as the entrance was wide enough, the flower vine lunged ahead, swiftly plunging its “pistil” deep into her maw while the petals folded forward, latching on and completely wrapping her muzzle inside the wet, sticky bud. The “pistil” stretched further in, sliding across her tongue and leaving in its path a half sweet, half bitter nectar. Before Luna could register what was going on in her befuddled mind, the stigma had already hit the back of her throat. The vile organ spurted out a glob of thick, slimy fluid into the entrance of Luna’s throat. And with the lubrication in place, it pushed forward, promptly slipping in the tight tunnel leading to Luna’s stomach.

The violated Princess immediately gagged and heaved. Her throat convulsed, trying to push the rude invader out, to no avail. It went on pulling more of itself out from inside the vine and into the alicorn. The thing kept lubricating the path ahead with spurts of thick slime, then slipped further in. Luna’s throat was slowly expanded and packed tight, to the point when her gaging reflex was simply some twitching of her inner flesh as it could do nothing more than hugging the alien organ a little tighter.

The stigma stopped just before it reached her stomach. It lay there, still and quiet for a while. At this time, the vine on her horn had slowed its magic sucking back down to a trickle, releasing Luna’s mind to fully experiencing the violation of her body. She could barely breathe though the small gap left in her windpipe by the expanded gullet. The petals around her muzzle closed in tight as dozens of the inner tentacles freely molested her skin with their greasy touches. Her tongue and upper mouth was forced hard on the slimy “pistil”, compelling her to thoroughly feel it disgusting taste and texture. Yet, she dared not bite, lest that vile thing was cut off and left lodged inside her.

And then, the “pistil” began to throb. Ripples of twitches and bulges were sent along its length from the base on her lips down to its tip near her stomach, causing her gullet to ripple as well and cutting off that small gap in her airway, suppressing her breathing pattern. Suffocating, Luna was forced to comply as the vine trained her to obediently attune her own breathing to its “rhythm”, submissively sucking in quick, tiny bits of air every time a ripple had just passed the back of her throat. All the while, the entire thing started to warm up, burning her inside.

Before long, the ripples were follow by spurts of fluid out of the stigma. Shot by shot gushed through the end of her throat straight into her belly, and hit the inner wall at the far end of it, making it lurch in perfect rhythm as if the vine was humping her stomach. The demeaning sensation continued for some time before the fluid began to fill up her stomach, prevent the next spurts from hitting her inner wall again.

Luna’s body twitched and shuddered the entire time it was disgracefully violated. Tears swelled up in her eyes as agony and indignation washed over her in waves. Even so, she could do nothing other than docilely submitting to the vines and enduring its treatment of her until it was over.

Eventually, the throbbing and squirting died down, barely before Luna’s stomach was filled to the brim. Slowly, she felt the “pistil” began to withdraw from her throat. Yet the sensation was in no way more pleasant. It had packed her gullet so tight that, as it steadily pulled out, it acted as a piston, sucking the sticky fluid it had pumped into her belly out through her gullet along with it. Luna cranes her neck painfully to try to ease the excruciating sensation. She found her dizzy mind unsettled between wanting the vine to slow down to lessen the feeling and wishing for it to speed up to get it over with. Not that the vine was actually concerned about her thought though. It just kept going on with its pace.

But at last, the “pistil” had reached the back of her throat. With a strong final yank, it plucked its vile organ out of her as the petals released her muzzle. Luna only had a second to prepare herself before her stomach lurched hard, and thick, gluey white fluid gushed out of her mouth glob by glob. She heaved and coughed. Tears streamed down her face as the sweet, bitter and sour taste assaulted her tongue. Dozens strings of the sticky fluid still stretched out between her muzzle and the small tentacles adorning the petals of the vine. The abominable flower stooped down as if gazing after the globs of liquid she had just expelled from her body, seemingly dejected as its “gift” was wasted.

After a long while of coughing and convulsing, Luna’s body went limp. Tears continued to flow from her half-lidded eyes as she let out choking sobs. It was only a start and the blue alicorn seemed to be ready to break down. She did not think she could get out of this intact anymore. Her clouded mind began to wander. Images of a regal white alicorn slipped into her thought, and her heart clung to them for comfort.

Oh how she wished for Celestia to be here, to save her! As much as she hated for her sister to see her weak like this, she could not help but longing for that calm voice, that graceful smile, that serene gaze, that soft touch, that warm kiss on the cheek from what seemed like an eternity ago…

Strangely, that thought seemed to affect the vines’ behavior. From the back of her cloudy mind, she could feel them vibrating softly, like they were communicating and contemplating something. The vibrations rippled through the magic stream that was steadily trickling out of her horn as well, as if the vines were reading her thought.

The vines remained like that for some time, lost in their conversation, as Luna slowly regained her breath. Then, she sensed movement. Very. Intimate. Movement. Something was slowly creeping up her inner thigh. Her eyes shot open. She looked down, and discovered another vine with something like a seed pod at the tip was advancing toward her very private part.

She was confused for a moment, then trepidation hit her. Her pupils shrunk and shook as she realized the creeper’s intention.

“No… No! Not there!”

She jerked, trying to cower into a ball to hide her intimate part, but the vines stayed firm and held her limbs in place, perfectly exposing her body for their friend. Desperate, she did the only thing she could do, squeezing the muscle between her hind legs as tight as she could with all her might, not realizing how adorably futile it was.

“Gaah!... Hah…”

She let out broken gasps as the soft but firm pod touched her marehood. To her humiliation, it felt slimy and slick over there. Had she been leaking? She squeezed her eyes and ground her teeth in disgust of herself. How could she let these foul creeper arouse her so? The only time she had ever wet herself was after that beautiful but absurd dream of her…

The vine pressed its pod hard against her lips, interrupting her thought. With all the slippery her body had disgracefully provided, it easily gained ground, parting her warm slit further apart. She squirmed and thrashed in desperation, unwilling to accept the inevitable.

“No! Stop it! Don’t… Aah! Aaaaah…”

Luna cried out as the pod finally slipped inside her. It was big, way bigger than what her innocent tunnel had prepared for. Her inner flesh strained to stretch itself apart to accommodate the alien invader, while the entrance to her tunnel quickly closed up behind it (or as much as it could close up around the thick vine), intimately enveloping the pod in her body warmth.

Tears streamed down Luna's cheeks. Her entire body shivered and shook, trying to cope with the agonizing sensation of fullness and the apprehension of what had happened. She felt so humiliated, so violated. No pony, no, no creature had ever touched her there before, except for Celestia. It had been long, long ago, when they still had been so very young, and had come about from an innocent filly wrestling play. Still, it was something special between her and her sister. And now, she had lost that to a foul creeper.

It would have been much better had it been Celestia doing it.

…

Wha...?

She blinked her teary eyes. Where had that thought come from? Why in Tartarus had she wished for Celestia...

The pod started to move, yanking her out of her wandering thought and pulling her back to the reality she was in. The vine began to push back and forth, advancing a little deeper each time. The thick, firm pod flattened her inside as it moved in and out like a burning hot clothes iron. The small but rough bumps on the vine behind it ground hard against her flesh as well, as if trying to assist the pod in shaving off the folds of her inner wall. One could see the pod’s movement through the small bulge it made in Luna’s lower abdomen. Her flesh cramped up around it, trying desperately to halt the cruel invasion, to no avail. Slowly, the pod adventured further and further in, caring not for the valiant but futile resistance the tight canal put up.

The vine kept on going, piercing through her belly, deeper and deeper into her core. Eventually, much to Luna’s terror and confusion, it hit her cervix. A shockwave of excruciating stimulation shot through the alicorn’s body. Never actually feeling that core of her before, she was crushed under the sensation. Powerful convulsions rocked through her as she was pushed over the edge. The vine did not back off, however. It continued to press its pod firmly against the entrance of her womb, as if giving it a loving, passionate kiss. The gesture rode Luna’s tattered body through a long, agonizing climax. Her eyes burned with tears. Every fiber of her muscles seemed to be snapping off under the intense orgasm.

After a long, mind-breaking moment, Luna went limp, nearly passing out from the extreme experience. The vine did not let her slack off though. Hesitantly parting with Luna’s cervix, the pod pulled back into her tunnel and once again began to pump back and forth, albeit with much quicker pace and longer, more powerful thrust. It did not go in a straight line, but instead curving and bending, kneading the roof and floor of her tunnel like it was trying to reshape her body to its liking.

Much as her mind wanted to shut down, Luna was jolted awake by the vicious pumping. Even as her body was trying to recover from the previous intense climax, the flame inside her groin was ignited again. With her body held completely in place, Luna could do nothing but choke on her sobs while the vine used her body as its toy, pumping in and out of her at its own pleasure.

The pod at the tip began to pound ruthlessly against her cervix. The agony from the savage assault made Luna’s spine twist and bend in three different directions within the small confine of her bondage. She could not tell how long until her body tore itself apart. The creeper did not seem to even notice, continuing to viciously ram the gate of her womb in an erotic siege, demanding entry into the citadel of her most intimate part.

Under the relentless assault, Luna’s cervix began to fold inward and stretch further and further apart. Bit by bit, the seed pod of the vine invaded deeper into the moist, fertile chamber, a heaven for its seeds. Finally, with a prolonged, persistent last push that sent intense spasms to every muscle in Luna’s body, the pod popped into her deepest confine with an audible sound. Immediately, the outer sepals unfolded, latching onto the entrance of her womb and completely securing the seed pod in place.

Luna felt her eyes boiled in her tears. Her mind was already near saturated in agonizing pleasure. All her limbs painfully cramped from as many as dozens of spasm already. Tattered feathers hang broken from her wings before detaching from her battered body and slowly drifting down to the forest ground. Luna was at her limit.

The creepers did not intend to let her off the hook that easily. Quietly, sneakily, another vine made its way to her behind.

Luna’s sluggish brain seemed to register it too late. By the time she noticed it, the vine had already been pressing hard against her tailhole.

“Noo… D-don’t… there… Aah… Aaah…”

Paying no heed to her despaired plea, the vine showed no mercy. It did not go in smoothly. Her anus was even tighter than her marehood, and all the space the previous vine had taken up in her body left little room for her flesh to stretch out any further. Nevertheless, the new vine was not deterred. It squirted a slimy liquid onto her anus. Then, assisted by the slickness, it slowly gained ground, forcing her stubborn anal ring to yield bit by bit.

Ultimately, with a loud pop, the vine succeeded in its conquest. Luna’s eye shot wide as she let out a broken shriek. Not waiting for her body to cramp itself up, the vine quickly pushed in further. Despite the coiling nature of her back tunnel, the creeper sadistically took a different strategy than its comrade, shoving in hard and straight on purpose, compelling her rectum to unwind itself to reshape to the vine’s chosen path. It kept on going nearly two horn lengths in before halting, then pulling itself back out fast, tugging at her untwined tunnel before releasing it to return to its original shape.

The sensation of her anatomy being pieced through mercilessly, then compressed and released like a spring at the vine’s cruel play made Luna choke on her gasps, unable to make out a comprehensible cry. Her body seemed to be slowly torn apart.

Then, all the while the vine was plunging in and out of her, ripples of intense vibration rode along it length. And before Luna even managed to regain a proper breath, the vine drove itself deep into her, and a tidal wave of thick fluid burst out of its tip, expanding her tube onward like a balloon. The stretching sensation made Luna felt like she was being ripped in half. Her throat contracted in a choking scream while tears bubbled out of her eyelids.

Just when Luna’s body was riding its second climax to the peak, she felt the seed pod deep inside her began to swell up as well. It slowly expanded, making her belly bulge out, stretching her womb apart and just adding more and more to the raging orgasm. Her mind seemed like being torn apart bit by bit. Her muscles wrenched, her nerves ripped and twisted. It went on and on, seemingly to no end. But at last, mercifully – or cruelly, one could hardly tell – the pod burst open, releasing a blast of hot, thick, milky fluid that quickly flooded her womb, and a single, miraculous seed.

As if to prevent her from hurting herself with the throat-ripping cry, the flower vine promptly plunged its red “pistil” back into her screaming throat. With excellent precision, it slipped all the way down her gullet in one push, smoothly lodging itself inside her while the petals latched themselves onto her muzzle again. Then, it promptly spurted a torrent of fluid into her stomach, feeding her full from this end once again. She gagged a few times, but then went limp. Her body seemed to have broken its limit, and could no longer react any further. It eventually gave up and embraced the ravishing sensation. The dreadfully pleasant feeling of fullness, having all her orifices affectionately sealed tight and filled up, began to spread throughout her every nerve.

As she was drown in euphoria, the burning heat radiating from inside all of her depths reminded her of the warmth from her sister’s sun. It was hot, but comforting; scorching, but titillating; alien to the coolness of her moon, yet arousing her deepest core. Little by little, she found her body accepting it, easing into it, melting into it while the pleasure slowly saturated her mind. Was this how she would feel if she had her sister, if she could touch the beautiful white alicorn’s core? Oh, what a blissful dream…

What if she could?

…

Would she want to?

Of course she would. Why would she not...?

Embracing that lovely mare tightly, inside and out?

Yes, that would be nice…

Forever staying connected with her?

Yes…

Strangely, Luna started to feel her heartbeat fasten and her breath ragged even as her entire body loosened up and her mind slowly slipped into a peaceful sleep. Somehow, there was something intriguing sprouting in the back her mind, arousing her imagination, making her anticipate for… something. What was she awaiting for? She was not sure. But something whispered in her mind…

Maybe nightmare could come true after all…

Solar Eclipse

Celestia blinked.

The dizziness was still clouding her mind as she struggled to regain focus. Slowly, the blurry images in her eyes began to come into shape, and her heart skipped a beat as she realized the situation.

She was suspended in midair, tied up firmly in a bondage of the strange black vines. She could not believe they had managed to subdue her that quickly, even with a surprise attack. And judging by the surrounding scene, they were even able to take her out of Canterlot into their hiding place, by teleportation perhaps? If so, these vines were no small fries.

She could sense the chaos magic emitting from the vines. Discord! That wretched draconequus. What was he planning this time? And yet, it felt strange. The magic she felt from the vines was chaos magic alright, but it felt… different. Ancient. Was it Discord after all? Or something else?

She scowled. That would have to wait. She needed to find a way to escape first. Took a glimpse at her horn, she grimaced. That vine that had latched onto her horn during the attack was still there, and was sucking away her magic. She was not gonna be able to use any spell at this rate. Escaping seemed to be not a simple task. She glanced away, looking for another solution, all the while trying to ignore the strange tingling sensation inside her abdomen caused by the magic stream.

Then, she saw something moving in the darkness in front of her. There was some rustles and thick sloshing noises, then a familiar but raspy voice reached her ears, making her heart skip both in relief and trepidation.

“Tia! You are finally here!”

The shadow before her began to move into the glimmering light. Her eyes widened at the sight.

Her sister Luna was also being held in the air by several vines, although they did not tie her up like Celestia herself. Her limbs and wings could move freely, her horn was not blocked off by a vine. Why she did not use her magic to escape was beyond Celestia. Then again, her body was battered and worn out, and she was panting heavily. But what made Celestia stare in horror was dozens of sticky strings of viscous fluid still stretching from the blue alicorn’s muzzle to an abominable-looking “pistil” of a flower floating alongside her. Disturbingly, her sister seemed to pay no concern for that herself. She kept smiling brightly, her eyes twinkled with happiness as she looked at the white alicorn.

It was kind of adorable. And hot.

Celestia shook her head, trying to banish the crazy thought. She called out,

“LUNA! Dear heaven, they got you too? What happened to you?”

Luna did not answer. The vines continued to bring her closer, and finally reuniting the loving sisters. Luna pressed her head against Celestia’s neck. Her forelegs wrapped affectionately around the white alicorn’s withers. Her breath was labored, like that of a pregnant mare on her due date. The sight squeezed Celestia’s heart. She nuzzled her head against Luna, whispering softly,

“It’s ok. I am here now. You are alright.”

Then, Celestia felt something warm and slick slowly trace up her neck. She pulled back with a scowl, and stared in confusion as she saw Luna’s extruding tongue, saliva still stretching between it and her neck.

“Luna… What are… URFF!”

Her voice was cut off as Luna suddenly lunge forward, pressing her hot lips on her own. Celestia’s eyes widened in shock. Her body froze in place. The warm, moist and sticky feeling of her little sister’s lips dazed Celestia for a few valuable seconds, leaving her mouth slightly open, giving Luna a golden opportunity. By the time Celestia knocked herself out of her stupor, something wet and hot, with a tang of sour taste, already invaded her mouth and caressed her tongue. Instinctively, she tried to pull back, but by this time Luna had held her head in place with her hooves, denying her retreat.

Celestia’s resistance quickly fizzled out under the stimulation. She felt a burning heat started to creep up her cheeks as Luna continued to swirl her tongue around her own, wrapping it, circling it in a sensual dance, whipping their thick saliva and some other fluid Celestia could not recognize together, then meticulously coating her tongue with it. A tingling feeling pinched at her belly as well, inducing her to close her thighs together. That was if she could have. Having her limbs completely tied in place by the vines, she could do nothing, not even squirming, to fight back the wet, salacious kiss and the titillating sensation in her groin. She could bite Luna’s tongue, of course, but she would never want to hurt her sister so. And somehow, the thought of chewing on Luna’s tongue made her face flush even more.

Celestia squinted her eyes, trying her best to wash the indecent thought out of her mind. Then, she felt Luna’s body lurch, and there was some squelching noise as the blue alicorn’s throat convulsed. A trickle of a viscous, half sweet, half sour fluid started to flow down Luna’s tongue into her mouth. Celestia’s eyes shot wide open again. She let out a muffle whimper of protest into Luna’s mouth. Somehow, that only enticed the blue alicorn even more, as she pulled Celestia’s head harder forward, grinding their lips together. The fluid began to fill up in Celestia’s mouth. She tried to stay still as much as she could, taking small bit of air through her nose, not wanting to risk inducing her swallowing reflex.

The vines seemed to have another idea, however. They lifted Luna up a little while their lips were still connected. Luna's forehooves kept holding Celestia’s cheek and pulled it higher, causing Celestia’s head to tilt upward and her mouth line up with her throat. The mouthful of the half sweet, half sour nectar slowly, dreadfully slid down the back of her tongue.

Celestia contorted her face as the warm fluid slipped into her throat. Yet at the same time, a deep red color burned up on her pristine white cheeks. She did not want to admit it, but somehow, the idea of Luna affectionately feeding her with her own mouth a warm, gooey vile meal she had meticulously cooked up in her belly titillated Celestia more than causing disgust as it should have been. The look of Luna’s face as she did so, with dreamy, half-lidded eyes and a pinch of magenta color on her cheeks made her look so cute as well. It had been a long, long time since Celestia last saw her sister in such an adorable state.

Celestia squeezed her eyes shut and tried to shake her head hard. What in Tartarus was she thinking? This was her little sister! She should be finding a way to get them out of this, not enjoying it!

It was a feeble effort on Celestia’s side though, as her cheeks burned up again when Luna continued to seal their lips tight and kept delivering more fluid into her mouth. Every time Luna’s throat lurched, a spurt of the thick, sticky and sickly warm soup gushed through their joined lips and hit right on the back of Celesia’s throat, inducing a swallowing reflex that pushed the stuff straight down her stomach.

The feeding went on for quite some time, and Celestia began to feel full. Thankfully, just as her stomach became kind of bloated, Luna parted their lips and ended the intimate feeding. As she pulled her head back a few hoof lengths from her older sister, a few thick strings of fluid still stuck between their muzzles, refusing to be severed. Celestia heaved and panted as she looked at Luna who was smiling fondly at her.

“Luna... What are you...”

Her words trailed off as Luna held her flustered cheeks up with her hooves and stared into her eyes. The longing eyes of the blue alicorn somehow felt so enticing, so captivating to her. So quietly, Luna whispered,

“I have waited so long for this, Tia. Today, we can be together.”

Having said that, Luna pulled back a little, putting her hooves on her belly. She gave the confused white alicorn an affectionate smile as she felt the movement deep inside her. Slowly, Luna began to tense up. Her spine arched backward, her mouth hang open in a silent scream. To Celestia’s horrified eyes, there was something moving inside Luna. A small bulge appeared on her belly, moving steadily down her abdomen toward her groin, getting bigger and bigger as it went. It halted just at the bottom of her body as if getting stuck. A large amount of sticky fluid dripped down like honey between Luna’s hind legs. At the same time, Luna’s torso twisted and convulsed. She let out a broken cry and, under the terrified gaze of Celestia, a large green vine with a big bulge at the head popped out of Luna’s body with a sickening “PHLOT” sound.

Luna’s head drooped down limply as she gasped for air after the excruciating “birthing”, saliva leaking out from the corner of her mouth. All the while, Celestia could do nothing but stare at the abominable thing squirming out of her little sister, coating in a thick layer of sticky honey that dripped down on the forest floor in gluey strings. She could not move a muscle as the vines pushed Luna back into her chest, her gaze kept following the squirmy thing until a dark blue body pressed into her, blocking it from view.

Very slowly, Celestia looked up into her sister’s eyes with terror on her face.

“Luna… What…”

Luna simply looked back lovingly at her.

“Don’t worry, Tia. Just relax. I will take care of you.”

Then, the blue alicorn nuzzled her head affectionately at the pristine white neck, while her sister stared on in shock. But soon enough, Celestia jolted out of her daze as she felt a slimy and firm thing touched her private part. Her pupil shrank to pinprick, finally realizing her sister’s intention.

“Oh Celestia…” Luna cooed into her sister’s coat.

Celestia jerked violently in panic as she felt the pressure built up more and more between her hind legs.

“Wait! Luna! Wait! Don–aaaAAAHHH!!”

A heart-wrenching cry escaped the white alicorn as the vine gave a powerful push forward, promptly parting her innocent lips and slipped inside the unsullied canal. She stooped forward into Luna’s embrace, gasping for air as her body strained itself to accommodate the insolent guest. The vine did not wasted time waiting for her to recover, however. It quickly gave a deep thrust, ramming two entire hoof lengths in with one stroke, piecing through the alicorn’s body. Then, it leisurely withdrew, tugging at her wall as if trying to take her core along with it. Just as it slightly parted her lips against, it gave another fast thrust, shoving itself back inside.

Sensing the vine starting to get into its rhythm, Luna gave a satisfied smile, and pulled back to look adoringly into the white alicorn’s daze eyes. Trying her best to regain her focus, Celestia used all her might to stare down Luna, although it was not at all that effective with the flustered face and the quivering mouth of hers. And so, all she gained from it was another loving kiss from Luna and a particularly affectionate thrust of the vine.

Celestia’s mind began to get cloudy. The meticulous, sensual thrusts sent lighting through her core. Her flesh was stretched apart to the limit it had never expected to experience before. Every time the vine shoved itself in, it felt as if air was pumped out of her lungs. But slowly, agony started to mingle with pleasure, as the tingling feeling in her groin before was ignited into a full raging fire.

Celestia’s heart started to waver as her sister nuzzled into her neck again. The comfortably warm feeling from the cuddle, embroidered with the piercing sensation of every thrust into her core, seized at her body, compelling it to let go. The deepest part of her just wanted to surrender itself to the pleasure. But the other part of her kept screaming for her to fight back. Maybe it was lying to herself, but she could not just... go along with this, could she? Luna was her little sister. They were related. They could not do this. What would everypony think? Not that there was anypony around to see them, but still… No… They have to stop…

Using all the strength of her mind, Celestia shouted,

“STOP IT, LUNA!”

Luna’s eyes shot wide open as everything froze, much to Celestia’s relief. Taking advantage of the respite, she tried to recover her breath as much as she could before chiding.

“What in Tartarus… are you doing? Why are you acting like this?”

Silence reigned for a moment. Then, Luna very slowly pulled back. Despite her resolve, Celestia could not help but flinch as she caught a glimpse of Luna’s hurt-filled eyes.

“Why...? Can you still not see how I feel? After all this time? After... that night... a thousand years ago?”

Her gaze bore into Celestia as her eyes became glassy. Luna said with shaky voice,

“We used to be so close, so intimate, Tia. We did everything together... You used to rely on me, always follow me, always let me choose what we played...”

Luna turned her head to the side, tears swelling up under her eyelids. “But ever since Sombra, you had become different. More assertive. Distant... You started to have goals. You began to care about other things. Equestria, our subjects, maintaining peace, public affairs, entertaining the nobles... You were no longer the carefree Celestia I knew, the Celestia who loved listening to me, who were always by my side…”

She let out a choking laugh.

“We could not even prank each other anymore. You used to spend hours playing with me inside those secret paths and hidden rooms and traps we built in our castle.” Luna turned around, her watery eyes stared into Celestia’s own again. “But ever since we came back from that war, you no longer saw them anything more than nuisances! I was no longer in your eyes! Our subjects basked in your precious light, but I could not. Your affection shone on everypony, but not me.”

Celestia’s stomach wrenched. Her throat felt warm and sticky of guilt as she saw the pent-up tears slip down Luna’s cheeks.

“But worst of all, we no longer did things together... You just did everything on your own. You just took on everything by yourself. Ruling the nation. Handling the nobles. Dealing with the foreign sovereigns. You just did it all! You kept going on alone without me, even when it hurt you, exhausted you.”

Luna squinted her eyes. Tears were flowing freely on her face now, soaking her cheeks.

“And I hated it! I hated it so much! It felt like I was not the most important pony to you anymore. It was like you thought I was not good enough to even help you anymore... It hurts me so...”

Luna pressed her head against the side of her sister’s slender neck. Her eyes squeezed shut, streams of salty, raw emotions wet the pristine white hair of the older alicorn. Her body was trembling, sending emotional vibrations along the vine through Celestia’s canal into her belly, shaking up Celestia’s own heart.

“I could tolerate the insolence from our subjects. I could deal with their disregard of my existence. But I could not bear the thought of you, of all ponies, also thinking that I was incapable of sharing your burden, that I did not fit to stand by you, that you did not need me anymore... That was why I... lashed out, and lost it to the darkness. I just... I just... wanted you to recognize me again, to see me, to let me take care of you again. I just wanted you to let me be in charge for once, to give me a chance to show you what I could do, to earn a place by your side... again...”

There was nothing Celesia could say. Closing her eyes, she nuzzled her cheek against Luna’s ears, and gingerly licked the sobbing alicorn’s neck with her warm, wet tongue, trying to sooth her.

They stayed like that for a long time. As Luna regained a little of her composure, she pulled her head back to look into Celestia’s eyes. Their body still pressed against each other, their lips only a feather width apart. Celestia could feel her sister’s moist, heavy breaths blowing into her own throat as Luna whispered shyly,

“Please, Celestia... Will you... let me... be in charge this time?... Just this time? I will not disappoint you.”

Once again, Luna’s cheeks blushed a beautiful magenta shade against her blue coat. Celestia felt a burning heat creeping up her face as well. She stayed silent for a moment. Would she accept this forbidden love? Would she open herself to Luna, to let her sister reach into the deepest part of her, paying no more heed to moral, to dignity, to whatever everypony would think? Would Luna be worth it...?

Then, as a reply, Celestia closed her eyes and reached forward, gently pressing their lips together. Luna let out a surprised muffled cry, but quickly relaxed and pushed back, her mouth wrapping and sipping at her sister’s wet lips.

Sensing the rekindled affection between the alicorns, the vine protruding from Luna started to sprung into action again. It pushed further out of Luna’s marehood and into Celestia, scrapping against both the alicorns’ inner flesh at the same time, earning arousing moans from their throats that met and vibrated on their fondling lips. The bulb at the tip of the vine was slowly pushed deeper into Celestia’s body, stretching and flattening out her inner folds. It steadily finished the final distance of her tunnel in one stroke, and finally met and pressed hard against her cervix. The lightning bolt it sent through her body made Celestia jumped and thrashed wildly, but Luna quickly wrapped her legs and wings around her sister, and with the assist of the other vines, held her in place.

Being denied even the little relief of squirming, Celestia was compelled to suffer the full force of the raw sensation. It was something she had never experienced before, and that made it even more unbearable. Celestia cried out her muffled anguish into Luna’s mouth, begging for an alleviation. Sensing the white alicorn’s distress, Luna parted their lips to allow her sister to let out the overpowering emotions.

“Lun... ah.... aah... Too deep... I can’t... Too much...” was all Celestia managed under the convulsion. Before she could voice any other complaint however, Luna gingerly pressed her forehoof on her sister’s lips, cutting her off. She leaned in and gave a wet lick along the side of Celestia’s muzzle, making the white alicorn shiver even further, before whispering into her cheek,

“Just relax, Tia, and give all of yourself to me. I will take care of everything.”

With that, she traced her lips back to Celestia’s own and locked mouth with her sister again, completely sealing off any further protest deep in the white alicorn’s throat. Together with the vines, her legs and wings tightened up around Celestia, fully rendering her body safe and secured.

Now that it was given some leverage, the vine connecting their pussies started to pick up the pace, ramming the entrance of Celestia’s womb repeatedly. Every time it went in and out, it rotated several rounds, mercilessly wringing Celestia’s tunnel like a wet towel, causing the alicorn’s spine to painfully twist and bend along as well. The pod at the tip of the vine did not simply battered Celestia’s cervix. It drilled into it, getting deeper and deeper every time using the rotation, much to her anguish. The rotation went all the way back, up into Luna’s womb, allowing her to enjoy the same agonizing pleasure her older sister was being subjected to, much to her delight. Luna knew her sister had always been uptight about these feelings, and she knew because of that, this was even more excruciating for Celestia than it had been for her. That was exactly what Luna desired. She wanted to screw the lovely white alicorn up as hard as she could. She wished to embed the most mind-breaking experience into her sister’s memory, from now until the end of their immortal life.

And judging by the muffled yet throat-ripping cries Celestia was screaming into her mouth, she was succeeding. But this was just the start. She had waited, tolerated so long for this moment to reconnect with Celestia, to bond with her sister again that she would not stop until it had been done thoroughly, inside and out.

Wet, squelching sounds echoed through the dark forest as the green vine continued to swirl and pump back and forth between the two alicorns’ intimate parts, whipping their thick, slimy love juices together into a fine blend. If listening carefully, one could hear a muted “SPLOTCH” every time the bulge at the tip of the vine connected with the white alicorn’s womb. To Celestia, it was a torment, but one that was filled with earnest love from her little sister. And so, despite the agony, she entrusted her heart, her mind and her body entirely in the hooves of the blue alicorn, and let herself drown in the torturous sensation.

Then, after a vicious drill, the seed pod lodged itself halfway through the warm gate to the alicorn’s holy chamber. Celestia’s whole body immediately went rigid, each of her muscles froze in a ripping spasm as her inner most core was stretched and torn to the limit. The vine was not discouraged however. It pressed hard forward while rotating back and forth, grinding the alicorn’s cervix apart bit by bit to advance in an excruciatingly slow pace. Celesia’s eyes almost already melted into tears when the pod finally popped into her sacred sanctum and unfolded it sepals to seal it safely inside.

Celestia went limp in Luna’s embrace, promptly passing out from the extreme session. In fact, the only reason she was still breathing after all those waves of excruciating stimulation was probably because sweet Luna had been giving her mouth-to-mouth rescue breaths all this time. Sensing that her lovely vine had succeeded in its task and stopped moving, Luna slowly parted their lips and carefully lean Celestia’s head back on a waiting vine. She then pressed her head against the white alicorn’s chest and closed her eyes, enjoying the weak, heaving breaths, the irregular heartbeats and the sweating warmth from her dearest sister. With an adoring smile, she lifted a forehoof to Celestia’s belly, feeling on the smooth skin the small bulge where the seed pod of her vine had snugly embedded itself inside her beloved sister, and immersing in the deep, deep connection they now had.

But no, this was not the end. She needed more! She wanted them to be completely, thoroughly connected together! An idea lighted up in her mind, and even she herself shivered at the thought. It would require her to take the lead, and that would be an absolutely wild venture, one she was not entirely sure she could follow through to the end. But for the euphoria of being able to truly become one with the most important pony in her life, she wanted to take it on, no matter how much hardship and challenge it brought forth.

“I’ll do anything for you, Tia…”

Finally making up her mind, she earnestly hugged the white soft body, drawing in some courage from her sister’s warmth and bracing herself. The vine growing in her sensed her feeling through the roots it had implanted in the wall of her womb, and recognized her intention. It responded immediately, simply too eager to give its beloved “bearer” an assistance.

Drawing magic from Luna’s body, the stem began to sprout new green vines inside her womb, nearly a dozen of them but much smaller this time. The new branches of vines grew, their tips gathered at the entrance of their cradle, which had been completely plugged up by the main vine. But they were gonna come out to the call of their “bearer”, no matter what! They valiantly pushed against the tiny gaps between Luna's flesh and the big stem, stretching her gate even further apart.

Despite her resolve, Luna choked on her gasps under the intense sensation. She squeezed herself tighter against her sister and bit her lip, trying to relax as much as she could. One by one, the new green vines popped through the entrance of her womb, earning a choking cry for each of them. Their path ahead was not any looser, but they got their momentum, so they kept pressing forward, pushing apart any fleshy obstacle in their way.

Finally, the new vines emerged from Luna’s tunnel one after another. They stretched out and curled upward, surrounding the two alicorns as if to present themselves. Luna was panting hard right now, her eyes watery. Glancing at her new creations, she gave an adoring smile.

The vines, understanding her approval, started to make their way back down to begin their mission. They gathered and coiled around each other to form a thick, long bundle of vines that was not that different from a single vine itself. Despite each new vine being pretty thin, when combined together they were no less formidable than the first vine that was still intimately connecting the two mares. The bundle they created began to stiffen, and slowly made it way toward... Luna’s tailhole.

Luna let out a deep breath as she felt the tip of the bundle press against her other hole. She quickly tried to relax as much as she could. The memory of the violation into that area she was subjected to not too long ago made her tremble. But this time, as she was willing to, it went more smoothly. With just a few pushes and probings, assisted by all the slickness they still retained from her marehood, as well as all the slimy fluid still remained in her tailhole from the previous assault, the vines already managed to stretch her hole apart quite considerably, getting half of the bundle’s tip inside. Emboldened by the progress, they gave a strong press forward, intending to finish the job early.

At last, with a wet “PHLOT”, the bundle of vine reentered Luna’s body, causing her to let out a broken shriek. Again, a feeling of fullness she had once experienced washed over her, though the sensation on her inner flesh was significantly different from the last time. The texture of the vines as they entwined around each other was neither smooth nor bumpy, but rather “twisted” and “spirally”. Nevertheless, it was tight. The threads of the spiral dug themselves into her anal wall, as if trying to mold her rectum into a big screw hole being fasten tight.

But that clearly was not the end of the total fullness they could give her, and the vines were quick to remind her of that. Withdrawing a large amount of magic, they elongated substantially, their tips plunging forward, and further in the screw went. Luna gasped for breath, her head slumped down on Celestia’s chest. The tingling sensation of magic being suck straight out from her womb combined with the feeling of being filled to the brim and over made her panting more and more erratic. The vines did not slow down, however, taking no regard to her distress. Every bit of the creepers emerging from Luna’s marehood immediately shoved itself back into her, simply too eager to be enveloped in the moist warmth of the alicorn’s body again.

Further and further in they reached, touching Luna in places she had never felt, or even thought she could feel before. They bent and wiggled all the way, leaning against each side of her tunnel and using that as a gripping point to pull more of themselves in. They slithered along her spine, all the way up to her rip cage and bumping hard against her inner wall before making a U turn. Then, they kept coiling around, going up and down, worming their way through her body. Sometimes, they pressed her inside hard against the front of her belly, causing her spine to bend backward. Slowly but surely, they continued to cramp more and more of themselves into her, packing her tight.

The sensation of her body being so deeply invaded and so mercilessly screwed up from the inside wrecked Luna’s frame. Her spine twisted and bent every which way whenever the vines turned, so much so that it felt like every one of her vertebrae was disconnected. Her cries were shattered into broken gags. In the back of her mind, she started to regret about this endeavor. She was not so sure she could pull it off anymore.

As if sensing her waver, the vine still joining her and Celestia gave a strong wave of vibration into her womb, just as to remind her of her true cause. It was barely noticeable to her given how intense everything was right then, but it was enough. As she just slightly opened her tear-soaked eyes, the blurry figure of an adorable white alicorn sleeping peacefully – or rather exhaustedly – came into view.

A flame was reignited in her unsteady heart. In a flash, she was reminded of the undying desire to become one again with her sister, to make the white alicorn completely hers, to share the deepest love between them. She remembered the yearning to fully envelop that beautiful mare with her very core, inside and out, to protect her from anything of this world, to never let them be separated again.

“Celes... tia...”

Luna let out a whisper of her sister’s name amid intermittent gasps of air. She brushed her tear-soak cheek against her sister’s coat, taking in the warmth from the white body as an encouragement. Regaining her resolve, Luna bit her lip and steeled herself for what to come. With a sickly churning sensation, she felt the vines plunged into her stomach. Her hooves clung desperately at her sister’s body as the force of the vines inadvertently pushed her up and up. The vines went about unwinding and spreading out, brushing their tips against the wall of her stomach. Then, the whole length of the things throbbed violently, and out from the tip of each vine a thick shot of some gooey fluid was sprayed into her. The squirts hit her hard in different directions, intensifying the churning sensation as they quickly filled her belly once again.

Just as Luna began to feel bloated, the vines started making their way toward her throat and forcing themselves in one by one. The feeling of something alive slowly crawling up and digging out of her throat from inside her stomach, amplified by her body being packed completely full and tight from end to end, was beyond anything Luna could ever imagine. It was unbearable. Every nerve end in each of her muscle ripped and tore in excruciating spasm. Waves and waves of raw agony crashed over her nearly wrecked mind, saturated it and pushed it dangerously close to being scorched out. She jerked her head backward, her mouth opened wide as gurgling sounds and saliva bubbled out of it. Her body convulsed and thrashed violently and involuntarily as her throat throbbed and gagged, trying desperately to push the alien things out as fast as it could. However, the creepers just took their time, advancing in a frustratingly slow pace, with no concern for the near-broken endurance of the poor mare’s physicality and mentality being pushed over the limit. Not that her body would be able to actually get rid of them any time soon anyway.

Luna’s seizure were so strong that it jolted the unconscious Celestia awake from her weary sleep. Her entire body still ached terribly, her coat and mane felt very sticky in places, and there was still a certain fullness and tingling feeling making itself known deep in her belly. Struggling to regain focus, she blinked several times, failing to register what was happening around her.

Until she finally noticed Luna, that is. Her sister’s posture was... off. Her whole body had risen up, looming over the white alicorn, and was completely still. Her head was thrown back, neck straight up to the chin. Both her forehooves were gripping tight at Celestia’s side.

Disturbed by what she saw, Celestia meekly called out to her sister,

“Luna... Are you...alright? What...”

Her words trailed off as the blue alicorn’s head slowly drooped down in front of her. Luna’s eyes were closed and full of tears. Her mouth was hanging, sticky saliva flooded out and trailed down in strings to their bodies. Her breath was ragged, but seemed to be steadily regaining its rhythm.

Then, Luna’s eyelids parted, and her gaze slowly lifted up to meet that of the white alicorn. Celestia found her heart skipping a beat. Oh those eyes! They were full of emotions. They were unfocused, yet somehow were boring straight into her own. Celestia could see the immense pain and suffering that had clouded those beautiful teal eyes, and still they were twinkling with tremendous love and pride (and tears), like a testament to her sister’s triumph over a grueling ordeal she had endured in the name of her undying affection for her beloved sister.

Luna began to lean toward the white alicorn. A deep blush adorned her cheeks, blending in with her dark blue coat to make a bright, beautiful crimson color. Her lips parted further, as if she was trying to call out Celestia’s name but could not. Her eyes continued to stare longingly at Celestia, so enticing and captivating that they kept drawing the older alicorn in.

But then, some movement caught the corner of Celestia’s eyes. She blinked, then immediately recoiled in horror. There was something wiggling out from the back of Luna’s throat. And there were more than one of them. They reached out toward her, pulling with them thick strings of white gluey fluid straight out from the blue alicorn’s throat.

Celestia kept on staring in terror and confusion. Then, in a flash, apprehension washed over her. Her body froze and her stomach knotted. She understood what Luna had done. And she understood what Luna was offering her. The thought alone made both her face burn bright red and her hairs stand on end. Her heart beat frantically and her throat clamped up. That was simply too much! It was impossible! She could never engage in such an act. Would she even dare to? Could her body even...?

But while Celestia was still recoiling in dread, her eyes caught a glimpse of Luna’s gaze again. And once again, she felt her frantic heart just skip. It kept piercing into her, that sad stare, full of sorrowful yearning and aching affection, wishing, asking, begging for acceptance, for love. Conflict flooded Celestia. Luna had done all this just to reconnect with her, just so they could share their deepest feeling with each other. Her sister had suffered, had gone through such an ordeal because of love, of devotion to Celestia herself. She had withdrawn her innermost self, her own very core, and was offering it to her. Would she be so cruel, so heartless that she would refuse that gift, that love?

A dozen of emotions clashed against each other inside Celestia. Decency, love, fear, guilt, disgust, longing, anxiety, excitement... All of them gripped and pulled at the white alicorn’s heart. Celestia’s body simply froze in place as her mind swirled in contemplation. Her wide eyes stared back at Luna in hesitation. All the while, Luna kept leaning in on her slowly. Their muzzles kept closing in on each other. For every bit of distance lost between their lips, Celestia found herself waver a little more, and a little more...

And before Celestia could fully made up her mind, their mouths connected. Once again, the sensation of Luna’s warm and stickily wet lips flood Celestia’s mind, washing over the hesitation inside and making her eyes unfocused. Luna pressed in further, slowly wrapping her forelegs behind Celestia’s head and pulling her into the kiss harder, as if trying to melt their lips together into one. At that moment, Celestia finally realized that it was too late. She had passed the point of no return, and could no longer resist her adorable little sister and break away anymore. Giving in to her fate, she closed her eyes and drowned herself in anxiety.

Eventually, something thin and slimy slipped into her mouth. And another. And another. They trailed a gooey fluid onto her tongue as they made their way toward the back of her throat. Celestia could feel a strangely strong, tangy taste, one that was kind of enticing. Then, her face blushed up furiously as she remembered where the vines had entered Luna’s body. Her stomach squeezed up a little bit. Still, it was a deeply intimate taste of Luna, a pure taste of her beloved little sister, and Celestia would not feel disgust of it.

Slowly, the vines gathers themselves, nearly a dozen of them, in front of her throat. They began to coil around each other again, and started to make their way in. Celestia’s body instinctively tensed up as she gagged and heaved. With the white alicorn having a larger figure, it went on somewhat smoothly for her without any suffocation. Still, her inexperience and her body’s tension did not make it too easy, as she still suffer from heavy gag reflex.

Tears began to leak out of the white alicorn’s eyes. The vines kept on going deeper, pulling more out of Luna and immediately into Celestia’s throat, allowing her to taste every essence of her little sister as fresh as it could be. Further and further down they went, scaring Celestia more and more as she did not know when they would stopped. If they would ever stopped. Gradually, much to the alicorn’s anguish, they pushed straight into her stomach.

The new addition into her belly made her feel bloated, with all the thick fluid Luna had fed her before still there. With the vines completely plugged up the entrance, not letting any stuff inside getting out, while they kept pulling more of themselves in and coiling around, her stomach gradually tightened up like a thick rubber balloon being over-inflated, ready to burst. The experience wrecked Celestia’s mind. All of her muscles strained tight just like her stomach under the sensation, ready to snap into pieces.

Then, for sweet relief, or maybe not, Celestia felt the vines plunge in deeper, releasing the stress in her stomach. Yet, her eyes widened, her pupils shrank and her brain went to overdrive, not expecting this turn of event. How much further did they want to go? They could not mean… She began to hyperventilate, as much as she could with the restrain in her throat, while her mind went into panic.

Suddenly, a faint but ensuring feeling entered her mind. It was familiar, soothing, intimate. As her eyes got back its focus, she realized Luna was staring at her. Boiling tears were still bubbling out of her half-lifted eyelids. Another vine had latched itself onto the blue alicorn’s horn, and the vines seemed to be helping them sharing their senses and thoughts.

But even as Luna was sending encouraging thought into her mind, she could feel the excruciating anguish of the blue alicorn as well. The vines were still slithering through Luna’s entire body to enter hers. The deepest core of her little sister seemed to be constantly ripped off and delivered into her. And yet, Luna was happy. Celestia could feel the deep affection that was almost literally pouring out of Luna and feeding into herself. Her eyes began to water as she could do nothing more than opening herself to accept that love.

The vines continued to coil around through Celestia’s body like a snake, scrapping at the parts of her she never felt before. Each part inside her belly felt like being twisted up into knot as the vines moved through it. Her abdomen was packed up tighter and tighter with slimy, wiggling vines. It was excruciating. But she had Luna now. They were together in their minds. Somehow, sharing their torments with each other made it feel like they could take on anything.

Finally, with a last few coils, the vines were heading toward Celestia’s final entrance. The sensation of something indecent trying to leave her body caused her to instinctively tense up. But with the encouraging thought from her Luna, she slowly ease herself and relax, letting the vines through. With a “PHLOT”, they emerged from her last tunnel, covered in thick slime and sticky juice.

But immediately, the vines turned around. Despite Luna’s comfort, Celestia choked on her gasp when the vines pressed against her marehood, wiggling around trying to find any gap between her outstretched flesh and the current occupant to get in. As if generously allowing the new comers to share its cozy home, the vine in her womb gave strong waves of vibration into her tunnel, rocking her inner core and making her lips wink. The winking of her marehood created just enough of a gap for the new vines. With a powerful thrust at excellent timing, the bundle of vines plunged itself into her overstuffed canal.

Celestia shrieked internally into their share mind as the vines stretched her body beyond the limit it never knew it had. The new vines twisted around the old one in a spiral, wringing Celestia’s core like a rope. They coiled around and around, until they reached the entrance to her sacred chamber. Then, they began to untwine themselves, each small vines positioned at a corner of her cervix and valiantly pushed through, paying no concern to the twists and bends of the white alicorn’s body in what were near-equivalent to dying spasms. One by one, they popped inside, finally reuniting with the lovely seed pod.

The two alicorns simply collapsed against each other. Their minds were nearly saturated to complete breakdown. But as they lay there in the protective bondage of the vines, they could not help but feel an ecstatic euphoria washing through their heart. Finally, after all these centuries, they had fully, totally, absolutely, become one with each other. Their bonds, their connections were complete, through their horns and minds, through their lips and throats, through their most intimate parts as well. They are secured. Nothing could separate them anymore.

However, much to the adorable sisters’ oblivion, the creepers had a final loving gift to them.

A dozen waves of throbbing shot along the small vines, rocking through Luna’s body. They traveled fast, so fast that Luna felt like her inner organs were being pull along up to her throat. Her eyes rolled upward, tears squeezed out from them as she convulsed and screamed her heart out into Celestia’s mouth. Or she tried to. All that came out were muffled squelching noises.

Then, the throbs shot into Celestia’s throat, making her pupils shrink into pinpricks. They pushed down along the vines into her throat, moving more slowly than through Luna but seeming like they were packing up more and more as they traveled along. Celestia thrashed and spasmed as she choked for air, but surely that could wait. Bulges by bulges started to form half way down Celestia’s throat, swelling up as they moved further down, then disappeared into her stomach.

Just as Celestia managed to gasp in the first small bit of air after the bulges had passed through, they reemerged in her perception again as they entered her intestine. They rushed ruthlessly through the alicorn’s body, pushing apart any obstacle, reshaping her anatomy to gain path to their destination. The white alicorn’s inside twisted like a spring as the bulges passed through.

Then, one by one, they popped out of the mare’s anus and back into her marehood, rippling along all the way into her final core. All the while, the seed pod in there swelled up massively as well. It expanded to the limit just as the first bulges travelling along the small vines reached the sacred chamber.

And then, everything erupted.

The only things anypony could hear in the Everfree Forest that moment was simply some rustling and sloshing sounds.

But, to a certain pair of loving sisters, what they heard in their heads were mind-shattering screams of euphoria, of affection, of love, as their minds, just as their bodies, were broken apart and melted back into one.

Complete.

Perfect.
