Twilight and Moon Dancer are studying together when a botched spell turns Twilight into a goo-pony. Kinky fun-times ensue.
Twilight and Moon Dancer are researching magic together, and Twilight gets a little too eager to test out their theorems. One botched spell later and she's a goo-pony with a pressing urge for physical contact. Moon Dancer is far too shy to initiate any kind of intimacy herself, so ends up being more than happy to tag along on the ride!
Moon Dancer put down the large tome she’d been poring over with a sigh and looked out the large window of the Tower Study to stretch her eyes.
“How are you getting on?” asked Twilight nearby, doing the same thing. The two of them had spent all day working on Moon Dancer’s current field of study, Teleportation. Advanced sorcery that was only usable by unicorns with an innate talent for magic. The objective was to see if there was a simpler method, something that any unicorn could master with practice, which itself might lead to many applications from a faster mail delivery network to rapid emergency medical response.
“Well, Haycart did put a lot of time into altering molecular structure for transfiguration,” she replied, watching ponies walking around on the streets below in their hive-like movement. “But he ultimately dismissed the idea as it wouldn’t go nearly far enough for the Word-Walker method and resorted to energy magic, which leads us back to the original problem.”
“Maybe that’s enough for us though?” proposed Twilight, “We don’t need to actually change shape since we want to arrive in the same state as we left. I’ve got a textbook on phase-states here, and I’m thinking if we could change our phase to much higher state that’s easier to move, the magical energy required to cover distance would be significantly reduced.”
“That’s assuming that altering a pony’s phase is any easier than changing to magical energy in the first place,” countered Moon Dancer.
The day had been long, but she had to admit that studying with a friend whom she could bounce ideas off of - especially one like Twilight Sparkle who could keep up with her - had been a pleasant change. Seeing another pony just as passionate about solving an intellectual problem as she was made her feel more confident about herself. She’d even found herself stealing little glances at Twilight, noting the slight furrow over her eyes as she read and contemplated the information from the book in front of her, occasionally pausing to scratch notes or references on her notes.
“Well let’s start with that shall we?” suggested Twilight, pushing the books in front of her away and turning to a fresh page on her notebook. “I’ll make this book gaseous, and then try to teleport it. We’ll see if it’s easier to move as a gas than a solid.”
“Well there’s no harm in that I suppose, although this is a very unfinished idea. I don’t think we’re anywhere near practical experiments yet,” said Moon Dancer, but all the same she walked back to the table and picked up a resonance meter so she could record the magic levels being used and compare them with their previously recorded baselines. Theoretically, any experiment they did that needed even slightly less magical strength than a normal teleport was progress.
“Phase Shift Teleportation experiment number one,” announced Twilight, her tongue poking out the corner of her mouth in concentration, “Begin!”
Her horn glowed with a swirl of her pink magical aura, which then appeared around a common textbook in front of her. There was a muffled pop and the book suddenly began to ripple like water.
“It’s going to blow away!” observed Moon Dancer, holding her breath while periodically glancing at the resonance meter.
Twilight quickly conjured a bubble around the experiment, which protected it from the eddy currents in the room. This was going to be additional magic, but proof of concept was more important at this point. Next, she cast her usual teleportation spell, concentrating her mind on the ghostly book’s current position and visualizing the destination, willing that vision into reality.
A tingling snap of magic echoed in the room, and the book moved to the table ten feet across the room, changing back to solid form in the process and landing with a thud. The two ponies both released their breath simultaneously.
“Well it looks like it worked,” remarked Moon Dancer, “You still used a lot of magic for that, well over the kind of target we need to achieve, however it was less than a direct teleport would’ve been…”
“It felt easier… I had to act quickly to stop the gas blowing away, but it felt as light as a feather when I actually teleported it. I think we’re onto something!” agreed Twilight excitedly.
The two of them caught eyes, sharing the excitement of discovery, and then Moon Dancer self-consciously looked away, clearing her throat. “Well, that’s just the start, a book is a far cry from a pony, but yes, we definitely have a theory to work on now instead of a bunch of vague ideas.”
“Honestly, I’m more than happy to try it on myself,” said Twilight, walking over to the table and inspecting the book. It was slightly soft, as if it had gotten wet and was still drying out, but other than that it was fully intact and still functioned as a book should. “I can ordinarily teleport myself from here to Ponyville at a push, I’m sure I can manage this method!”
“I don’t know Twilight,” said Moon Dancer, raising one eyebrow, “Surely if it was this easy Haycart would’ve finished his own work on this method?”
“You said it yourself, he abandoned phase magic because it wasn’t suited for Word Walker - that doesn’t mean it doesn’t work.”
Moon Dancer pursed her lips. Twilight was pushing forward much quicker than she would have preferred. Previously she’d spent weeks just writing essays on unfinished theories, but Twilight was moving to testing on the first day. It was exciting to work at such a pace, yet it also felt like she was missing a lot. Or could be missing a lot.
“Don’t worry, if this works we’ll slow down to analyse the results. We still need to figure out how to reduce the net magical cost anyway, but proving that phase-shifting before teleporting can save on the required magical power would be an amazing day-one discovery!”
“H’mm. Well, if you’re sure, Twilight. Ready when you are…”
“Okay, if you could transcribe for me - Phase Shift Teleportation experiment number two! I will create a bubble around myself right away to protect myself from convection currents in the room, then phase-shift to a gaseous form before teleporting across the room to the fiction bookshelf, approximately fifteen feet from here.”
Twilight assumed a stable stance that made spell-casting easier and performed the simple bubble spell again. So far so good. Next, she surrounded herself with her magical aura and channelled her magical energy to alter her physical state. A sense of weightlessness overtook her senses as her body began to break apart. She fully retained her sense of self, and with a soft pop, the feeling of her body vanished entirely.
It was unnerving, although exactly as she had planned. She tugged harder on the mental cords of her magical reserves to initiate the teleport, and with a flash and clap of magic appeared on the other side of the room in the blink of an eye.
But unlike a normal teleport, where she would be instantaneously able to move and sense again, she still felt far away. This would only last for a split second, but the change in sensation caught her off-guard. It was with a shock of surprise that she felt herself being compressed at great speed, as if a bucket of water had been thrown into the air and the water had reached its arc and was now crashing back down. The molecules of her body squashed back together with what felt like enormous weight - and bounced.
The was a strange, liquid sounding bloop, and then everything fell still. Twilight blinked, feeling like she had water in her eyes.
The sound of Moon Dancer gasping on shock made her turn around, and she saw the unicorn, books splayed around her, with both hooves covering her mouth, her eyes wide with shock and fear.
“What is it? What’s wrong?” asked Twilight. Her voice felt... wet. Like she had just downed a glass of water and still had liquid lining the top of her throat. She took a step forward and nearly fell over - her centre of gravity was different, and her weight seemed to wobble with a new inertia that felt completely alien.
She quickly sat down and raised one forehoof, and then understood Moon Dancer’s reaction. Her foreleg was translucent and wavy, almost like jelly, but somehow seemed to hold its shape.
“Wooah,” she exclaimed, raising her other hoof and inspecting herself. She appeared to be made of some kind of goop, closer to liquid than solid, and could now bend and flex in ways previously restricted by bones and joints.
“Are you okay?” wheezed Moon Dancer, visibly trying not to panic at seeing her friend’s current state.
“I… I feel fine,” replied Twilight, standing up and walking around again. She was quickly getting used to the new sensations now the initial shock was wearing off. She felt like a giant water bottle, her insides swirled as she moved, lurching forward if she stopped suddenly. She could feel a strange slick rubbery softness to her tongue, lips and mouth, which she seemed to be able to make disappear entirely by pressing her jaws together hard enough - and then reappear if she opened her mouth again. Likewise, if she pressed her forehooves together, they both joined with a ripple, like two beads of water combining. Then she pulled them apart again with a plop. “Err… experiment number two conclusion, there seems to have been some level of rebound with my phase-shift back to solid, and I’ve transformed into... I don’t know what…”
“A… goo-pony?” suggested Moon Dancer, quill and notepad floating in her magical aura, but no longer writing anything down.
“Uh… Yeah. It’s quite remarkable, we may be completely off-topic from our original objective, but we now have an entirely new phenomenon to explore!” she exclaimed, her face lighting up with curiosity. Moon Dancer looked less impressed. Curious, but curiosity tempered by concern.
“Explore?” she repeated incredulously, “Twilight we have to fix this! Can you turn back? Does your magic even work?”
Twilight glanced up toward her horn - which seemed to have a noticeable waggle to it now she was no longer solid - and furrowed her brow. Nothing happened.
“Err, no,” she said, “I can still feel my magic, it’s not like it’s been taken away, but I’ve got no way to channel it without a proper horn…”
“That would tally with unicorn biology,” commented Moon Dancer, walking up to her friend whilst taking notes, “The horn is an extension of the nervous system to the outside world, and acts as a focal point for our innate magical energy. It might be that you can still use your magic, but not in the way that you’re used to… Interesting…”
Twilight would normally have been quick to acknowledge that she knew this already, but as her friend approached and began to walk around her, studying her translucent body, she was feeling an overwhelming urge for physical contact. Moon Dancer just looked so… enticing. Solid, and contrasting to her own malleable body. What would it feel like to press her soft and gooey body against a warm, firm pony?
Moon Dancer set herself to focus on what she was seeing. Twilight looked as though she were made of jelly, however on closer inspection there was more to it than that - there was still anatomy here. Although her interior seemed to be a shifting mass of viscous liquid, it was denser in certain areas, forming lines and shapes that were unmistakably where her organs would be. Vague impressions of her throat, stomach and gut could be seen, with additional shadows of a heart and even a brain. Curiously her lungs and respiratory system were less apparent. It was a good thing she had retained her magical nature, since surely this form couldn’t support life without some form of magical drive behind it.
She was torn between scientific curiosity and wonderment. She was trying to remain objective and uncover what had happened, but at the same time Twilight was visibly excited and the idea was infectious. As Moon Dancer came to a halt in front of the good pony, Twilight suddenly leaned forward and threw her forelegs around her in a space-invading hug, causing Moon Dancer to squeak in surprise.
“Twilight! What are you doing?” she yelped. She moved to recoil, but couldn’t help but stay put and experience the moment. Twilight felt like, well, nothing she’d ever felt. She was like a heavy blanket or comforter draped over Moon Dancer’s shoulders, but unlike a blanket Twilight’s body formed perfectly over her in the most satisfyingly cosy way. It was like getting into a deliciously warm bath, except that the water didn’t soak into her, and moved of its own will.
Twilight pulled away again, leaving a trail of purple slime on Moon Dancer’s woollen sweater. They both broke eye contact awkwardly, Twilight visibly restraining herself from doing it again, and Moon Dancer knowing she should back away, but also wanting to stay put and experience more of the same thing.
“T-Twilight we should get you back to normal-”
“Wait, let me do that again… just… we’ll fix this in a minute it just feels nice,”
Twilight stepped forward and leaned into Moon Dancer again, feeling her liquid body deform against the unicorn’s mass. It was heavenly, there was so much surface area to contact. It wasn’t like a normal hug where bones and joints got in the way and made uncomfortable jabs, it was like hugging a huge soft toy, except that she was the toy. All she wanted was to touch as much of Moon Dancer as she could, and without even thinking about it she pressed herself around her friend’s sides so they were practically sharing the same spot in the room, face to face, close enough to see each other in perfect detail.
“H-hi…” stammered Moon Dancer, not sure what to do, a blush darkening her cheeks.
“Is this okay?” asked Twilight, hoping with all her being that Moon Dancer would say yes. She nodded meekly in reply, her breath nervous, eyes locked onto Twilight’s.
“Y-You feel… it’s like a spa mud-bath, but I can feel you moving against me…” stammered Moon Dancer. Twilight nodded in agreement. She could feel the same thing, her soft gooey form spread against Moon Dancer’s chest, and Moon Dancer’s steady breathing pushing her back and forth. Without even thinking about what she was doing, Twilight touched her lips to Moon Dancer’s.
Just a peck.
Moon Dancer blinked, her blush deepening into the full spectrum of the setting sun, but she didn’t turn or try to move away. Twilight kissed her again, holding her soft lips to Moon Dancer’s comparatively firm, but still soft mouth. The silence in the room was deafening. The feeling of their bodies pressed together now equalled by the kiss. Twilight gently touched her tongue against her friend’s lips, and at her command, Moon Dancer’s lips parted slightly to let her own tongue peek out to meet it.
As they grew accustomed to this contact, Twilight relaxed her mass a little more and began to sink over Moon Dancer. Her body oozed like lava, but rather than stretching, she seemed to gain size as Moon Dancer displaced her middle, letting her flow even further until half of Moon Dancer’s entire body was now enveloped by lavender slime.
Moon Dancer moaned softly, not sure what to do, but quickly becoming intoxicated by the sensations she was receiving from Twilight. Her body felt wonderfully warm and soothed by the liquid embrace, while the intimate kiss held her focus, keeping her brain preoccupied from wandering onto potentially more important things like reversing Twilight’s predicament, or the possible danger she was now becoming part of.
From the outside, Twilight seemed to have become somewhat amorphous as her mass spread over the bulk of Moon Dancer’s frame, filling in every gap and crevice between her limbs, caressing every part of her body. Finally, her forelegs started reforming behind Moon Dancer’s shoulder blades, and before either of them knew what was going on it was no longer a matter of Twilight covering up Moon Dancer, but Moon Dancer being inside Twilight’s chest.
At this strange angle, Moon Dancer’s glasses that were already askew slipped off and clattered onto the soft carpet. “Mmmmf,” she mumbled, interrupting their kissing for a moment, “Twilight- we should stop for a moment… we don’t know what’s happening here…”
“It’s okay, it’s fine,” Twilight reassured her, whilst her reformed front hooves settled on the ground again behind Moon Dancer, “Let’s just… we’ll just, see what happens…”
Moon Dancer glanced down, her eyes widening in amazement as she saw her entire body now enveloped in purple goop, her hooves no longer touching the ground, but now treading on the outer bubble of Twilight’s form, completely wrapped up and separated from the outside world. Concern fought with bliss as she saw that her sweater seemed to be separating. It was a shade of purple itself, but saturated with Twilight’s ooze it was dissolving like tissue paper in water, unveiling her light-tan coat underneath. What’s more was that her legs, while almost floating in Twilight’s mass, now felt like they were being gently pressed together from all sides, Twilight’s body seemingly trying to draw her into a liquid belly.
Twilight distracted her with another kiss, driving away her concerns and her fears with more soft contact. She could shape her tongue to perfectly wrap around Moon Dancer’s, extending right into her friend’s mouth to make their tender interlock completely effortless. Moon Dancer’s head was now angled up, with Twilight leaning back as the unicorn was completely engulfed up to her neck, with even her tail pulled in and slicked around her hip. Twilight had no idea what she was trying to achieve, but the wonderful sensation of touching and caressing every exposed part of her friend was now an obsession. The pleasure and communion only grew as Moon Dancer sank into her now noticeably larger body, and she was certain that some ultimate climax or goal would be unlocked if Moon Dancer became fully submerged.
She opened her mouth wider and without hesitating pressed her muzzle over Moon Dancer’s head, muffling the shocked moan that followed. With the unicorn’s body already trapped inside the barrel of her chest, Moon Dancer’s head and neck passed through Twight’s own neck as she swallowed her head and with an audible gulp settled in the space where her esophagus would be, while the bulk of her body wobbled into the stomach.
Moon Dancer’s world turned a lavender hue as without warning Twilight appeared to swallow her, and she found her head trapped in a stretchy tube inside Twilight’s neck. There was a little air trapped in here, and as Twilight experimentally stretched her jaws, Moon Dancer caught a brief, normally coloured glimpse of the Tower Library framed by Twilight’s open mouth, and then the slimy goop her friend had become rejoined and closed off the throat entirely.
The shock of being swallowed entirely momentarily cut through the hormone-fueled haze that had clouded Moon Dancer’s brain enough to let this happen in the first place, and she immediately cast a spell of underwater breathing. It was temporary, with a longer lasting version requiring more concentration than she could muster right now, but at least she wouldn’t drown or suffocate for the next few minutes.
“Twilight!” she yelped, her voice dampened not only by the viscous fluid around her but also Twilight’s loud and drawn out moan of pleasure as she fully absorbed her friend into her core.
“Sssshh sssshh,” Twilight cooed, leaning back and swallowing several times to push Moon Dancer completely down into her bubble-like stomach, “It’s okay I won’t hurt you, just, don’t you feel how wonderful this is? It’s… it’s incredible, I’ve never felt so close to somepony…”
Moon Dancer felt herself blush again. Despite her brain screaming at her that this had gone much too far, her body wallowed in pleasure, massaged all over by the heavy weight of Twilight’s body wrapped around her, touching and stroking every muscle from her shoulders, even down to her thighs - and between. It felt like being inside a balloon that was being deflated around her, vacuum sealed and submerged into a warm bath. She found she was still able to move, but on the inside, Twilight seemed to behave like a non-newtonian fluid. Gentle movements were possible, but as soon as she exerted any kind of force, Twilight’s goop locked up solidly, binding her in place. Relaxing was rewarded by both a little freedom of movement and a greater sensation of Twilight’s involuntary caress. She began to feel so relaxed she could just melt there and then.
Twilight had leaned forward into a sphinx-like position, eyes closed in bliss as felt Moon Dancer feebly move with her. It was heavenly, she could feel her slime seeping into the unicorn, weaving into the fibres of her coat, soaking into her skin, the taste seeping into her - the whole experience amplified by Moon Dancer’s slow surrender to her steady advance.
Finally, as Moon Dancer’s brain began to melt again under the onslaught of sensory pleasure, she felt a tingling jolt as Twilight’s embrace brushed against her clit and her eyes shot open again with guilty surprise. She looked blearily down at herself, curled up in Twilight’s centre, cocooned in a warm heavy goop, and- dissolving.
She was dissolving! A pale wisp surrounded her body, and her hooves were visibly rounded as she was beginning to diffuse into Twilight’s mass, a tingling sensation that spread across her. That was too much, she didn’t want this experiment to end in her body getting liquified into a goopy Twilight, no matter how- unbelievably good it felt.
“Twilight! I’m dissolving! You have to get me out of here right now!” she shouted. She tried to pull her hooves back and curl tighter and pull away from Twilight’s ooze, but the sudden movement did nothing else but jam up her surroundings again, locking her in place.
Twilight’s eyes snapped open. She had spread so much over Moon Dancer now that she could sense every fractional movement she made, and for the first time now she felt a tremble that wasn’t of nerves or uncertainty, but true fear, and the spell they had both covered themselves with evaporated.
“Oh goodness!” she exclaimed, getting up and stumbling back, only to realise that she was carrying Moon Dancer in her belly now, and couldn’t just let go. “Hold on, I’ll get you out of there… just give me a moment to figure out how!”
How indeed, she thought in her brain. She couldn’t move her insides like she could her wings or her legs - however, she suddenly remembered Moon Dancer mentioning her magic, and she focused on that instead. The familiar swirl of energy inside her was there, and her mind focused on that. Thinking as if she were trying to levitate her own mass as she would a teacup, she felt the unicorn inside her slime and realised she could control the distribution and concentration of it. Slowly, she nudged and pushed, and Moon Dancer’s compressed body was pressed up against the stretchy surface tension of her body. Then she relaxed, and Moon Dancer flopped out from her chest onto the carpet in front of her. At the same time, Twilight felt herself diminish in size again, her middle collapsing in on itself until she was the same height as she’d started out.
The air in the room was warmed by the strong sunshine blazing in through the huge floor-to-ceiling window, but after being inside Twilight, Moon Dancer felt chilly as she lay out on her back staring up at the roof. Bits of slime clung to her in clumps as she panted.
Once she’d gathered her wits again she looked over at Twilight who was sat upright stock-still, her translucent hoof covering her mouth in concern for her friend.
“I… I’m sorry,” stammered Twilight, her eyes shimmering, “I didn’t mean to hurt you- are you okay?”
Moon Dancer raised her hoof to inspect the damage, but to her surprise and relief, found it to be entirely whole and solid again. Had she imagined herself dissolving away?
No, she thought, I know what I saw, and what I felt… Twilight’s body had definitely begun to erode away at her. She’d been in her stomach and everything. But now she was outside, the effect seemed to be reversing. She wondered how much longer it might’ve been before the damage became permanent. Curiously, it was not with a shudder that she imagined it, but with a strange sense of lust. The memory of that full-body stimulation was still fresh in her mind - however committing to something that appeared to be at best permanent, and at worst fatal was a step too far.
“I’m okay,” she finally replied, propping herself up with her forelegs behind her. “I think we stopped just in time there, but…”
“You’ve never felt anything like that?” completed Twilight. Moon Dancer nodded in agreement. Twilight felt the relief that her friend was unharmed and unscarred by her experience warm the chill that had crept into her - and suddenly the urge for contact rushed back with vengeance. “Can… can we try it again? I think I’m getting the hang of how to control myself now… we can stop before anything bad happens…”
Part of Moon Dancer flared up in annoyance that after such a close shave Twilight had the gall to ask her this - but then again, the kiss, the embrace, the feel of being wrapped up in that warm goop, it was overriding her common sense. Looking at herself, she could feel the touch from the patches of purple slime still clinging to her all over in blotches.
Twilight followed her gaze and blinked in surprise. She could still feel Moon Dancer. The sensation was faint, but those patches of goo on the unicorn’s coat were part of her. Separated by an air-gap her senses were vastly diminished, however the unmistakable feel of a foreign pulse was there. Twilight focused her magic again, and her slime twitched. Moon Dancer jumped as she also felt it, and Twilight imagined that she was holding Moon Dancer again.
Moon Dancer, touched one hoof to a patch of goo on her side and found that it had turned sticky, glueing her hoof in place! She yelped and fell on her back again, instinctively moving her other hoof to wipe herself clean and getting that one stuck as well.
“Err Twilight, maybe we should figure out how to get you back to normal before we uh… do another test…” she said, straining against her bonds. Unlike a rope that would dig in, her forelegs were merely stuck, making this strangely gratifying, but they could do this another time - when things were a bit more under control.
Twilight approached her and gently stroked Moon Dancer’s hind legs from thigh to fetlock, leaving a trail behind. She slowly closed the unicorn’s legs again, binding them together so she was now laying completely helpless on her back with Twilight standing over her.
“It’s okay! See? I’m getting the hang of this…” she reasoned, “I think it was because you were in my stomach… if I put you somewhere else I don’t think you’ll get dissolved, and even if something happens, I can just push you back out again… it’s fine see?”
Moon Dancer’s common sense was telling her that things were anything but fine - but the memory of being inside Twilight’s soft, warm embrace, and now the strange allure of being at her mercy was eroding her reasoning skills. The tantalising promise of sharing that sensual touch and another kiss. If she didn’t roll with the situation now she had no idea when or if she’d ever pluck up the courage to get into a situation like this again.
Her lack of objection and evident wide-eyed curiosity was enough for Twilight, and with hooded eyes, the jelly-like alicorn advanced on her helpless body and sat down at her hind hooves with legs parted on either side. It took Moon Dancer a few moments to realise where this was going, and by then Twilight had picked up her hooves and aligned them with her exposed and glistening marehood. With the afternoon sunshine illuminating Twilight’s translucent insides, Moon Dancer could see the basic shapes of a vaginal canal leading to a uterus.
This is absurd, she can’t possibly go through with that! screamed Moon Dancer’s brain. But he burning curiosity had already seen the goo-pony grow considerably in size when another mass displaced her own - and with her viscous flexibility, the idea of her absorbing Moon Dancer up into her inner chambers was far more plausible than a first impression would suggest.
Twilight, oblivious to her friend’s internal dilemma, had already squeezed Moon Dancer’s bound hooves into her slick folds, letting out a low moan as she did so. Using her newfound ability to change her surface tension from slick to sticky, she grasped Moon Dancer’s thighs and pulled her closer, feeding her legs into her expanding pussy. As Moon Dancer’s legs slipped into her body up to the hocks, she could both see and feel herself growing larger again, making room to draw more of the unicorn inside into an even more intimate embrace than before.
Moon Dancer wanted to say something, anything at all, be it an objection or some nonsensical pillow-talk, but the blissful sensation of Twilight’s goop spreading up her legs and between her thighs stole her voice away, leaving behind a series of short breaths and gasps. When her wider hips lodged in between Twilight’s, there was a pause as they both wondered if Twilight could proceed - however Twilight was almost twice the size of the unicorn now, and her stretchy labia had no such trouble contracting and sucking in Moon Dancer’s rump with a muffled gulp.
As Twilight’s liquid slime touched Moon Dancer’s own quivering marehood, the unicorn couldn’t help but moan aloud. The warmth, the pulsing, living sensation against her clit - better than even a tongue would be if she’d ever experienced it - the touch set her on fire, driving away the last of her inhibitions and leaving her desperate to fill up the growing slime pony before her. Alas, still trussed up by the sticky patches all over her, she was just a passenger, willing Twilight to swallow her up.
Twilight was all too happy to oblige. Her ability to manipulate her mass at will gave her unimaginable control of her vaginal muscles - and she had retained all sensation of her sensitive areas as well. With the best third of Moon Dancer’s body now in her tight grip, she was able to steadily pull the unicorn inside herself no-hooves, feeling the pony equally fill her up and expand the space she occupied. She could even feel the thinner slime of her secretions flowing around Moon Dancer’s trembling pussy, and with a little focus, she parted those velveteen walls and probed inside her friend.
Moon Dancer was in up to her waist now, her forelegs pressing into the soft walls of Twilight’s inner thighs on either side of her, half day-dreaming that Twilight would just close her legs, squashing her between those gloriously enlarged hips - but even as she started stealing herself to ask, she felt Twilight’s goo slip between her folds and begin filling up her pussy with warm, pulsing slime.
She gasped aloud and arched her back involuntarily, her eyes meeting Twilight’s. The goo pony smiled, gauging if she was hitting the right spots or not, and Moon Dancer meekly nodded in approval. The signal to keep going received, Twilight set about pushing herself further into Moon Dancer’s passage, feeling her rippling walls against her convulsing goop.
“T-Twilight…?” stammered Moon Dancer, gasping between every syllable.
“Is it okay? Does it feel as good for you too?” asked Twilight anxiously. Moon Dancer nodded immediately, wriggling against her bonds and the grip of Twilight’s slick and enlarged canal.
“Could- could you close your legs?”
Twilight paused her motions for a moment of confusion, and then she realised what Moon Dancer wanted and smiled alluringly. She reached down with her forehoof and brushed Moon Dancer’s fringe back with a trail of slime, and then let the hapless unicorn lick and suck on the gel-like hoof tip for a moment. As she moaned against Twilight’s petting, Twilight closed her hind legs together, squeezing Moon Dancer between her soft thighs. Her thighs acted like balloons, pressing in against Moon Dancer’s upper body, surrounding her until she had just a crevice to breathe through. And breathe she did, her gasps getting louder and more frequent as Twilight’s goo-like phallus in her pussy convulsed and expanded, and all the while her entire body slipped deeper into Twilight’s love passage.
Moon Dancer’s hind legs were inside Twilight’s womb now, the internal walls stretching against the hooves poking into them. Glancing up at the huge see-through alicorn she was buried in, Moon Dancer felt a wave building from somewhere deep inside her. Her mouth touched Twilight’s over-sized clit, and without thinking, she began to suck, and at the same time, the wave inside her broke free.
Twilight felt her friend jerk and twitch as she orgasmed inside, and at the same time she clenched down, forcing the unicorn’s head into her stretched pussy, and tugging her body into her womb along with a hazy mix of slime and both of their bodily fluids.
“Oooooh!” Twilight moaned aloud, “Oh my stars this is amazing…”
She laboriously got up, tall enough to see over the top of the bookcases, feeling the liquid swirl of her goo move inside her like a maelstrom, and now a more stable, solid weight in her lower abdomen. Twisting her neck around she looked down her huge flank and saw the fuzzy shape of Moon Dancer curled up in her womb, feebly pushing against the walls enveloping her in a skin-tight embrace, working their way into every part of her.
Moon Dancer’s senses were all jammed on either overwhelming or smothered. Her body gushed with hormones and emotional rush, while her vision was blurred, hearing muffled, and nose blocked. She was vaguely aware of Twilight standing up, and feeling the huge mass around her move with such power and ease made her feel small and insignificant, now just a small part of a greater whole, wrapped up inside Twilight’s inner chambers to be- well, she didn’t even care what happened to her now. If she’d ever thought that getting out of bed at the crack of dawn after a late night was hard, that was nothing compared to having to leave Twilight’s wondrous body now.
The goop in which she was suspended filled every orifice on her body, touching and caressing her, stroking her into slumber. It soaked into her as she’d felt earlier on, but there was no sensation of it eating away at her this time. Looking at her forehooves tucked in front of her she could see they were fully intact, but her body was becoming rounded, taking the form that Twilight’s womb was imposing on her.
She no longer felt her hind legs or rump as flesh and bone anymore. There was something there, but it felt curvaceous, malleable, goo-like. Feeling no need to breathe at all, Moon Dancer’s head slipped under the surface of the tan-coloured goop she was melting into, her mind falling into a dream-like state.
Twilight was cross-eyed, her knees trembling, pussy dripping, feeling the torrents inside her body twist and gush about her guest. Not trusting her legs she sat back down again. With just the pressure of her weight on her ass and pussy, her tension broke and she came.
Spreading her legs wide again, her pussy gushed a stream of pale yellow goop that splattered into a puddle on the carpet in front of her. As it had before, her body shrank as the remains of the pony inside her were pushed out, the shrinking itself forcing the torrent of goo to continue until every last drop arced from her folds into a viscous blob.
As the high of her orgasm levelled out again, her first thought was that of shock. What have I done? she shouted inside her head, eyes fixated on the pony-sized puddle of slime before her.
But before horror or shame could sneak past adrenaline, the surface of the tan fluid began to ripple and shimmer of its own accord.
Moon Dancer stared up at the arched ceiling, feeling utterly spent in all ways it was possible to feel spent. She felt deflated, as though she’d just laid out on her bed after pulling an all-nighter. But unlike having spent until dawn squinting at books, she felt strangely refreshed.
And most of all, she felt very, very satisfied.
Glancing down, she noticed that the carpet was at eye-level, stretching out around her like an ocean - which couldn’t be right as her head would be too big to get this close to the floor. She lifted her head and heard a dull liquid sound from nearby. Looking down she saw a pale pool of fluid the colour of her coat, and immediately recoiled in shock. Her forelegs lunged out of the pool, diminishing its size a little, and she used them to try and shuffle backwards.
Twilight watched with open-mouthed fascination as Moon Dancer climbed out of the apparently flat puddle of ooze she’d extruded. The goop clung to Moon Dancer’s limbs as she clambered to her hooves, in the way that water droplets joined a larger body and melded into it. She was translucent like Twilight was, and visible currents and eddies of a thick fluid could be seen inside her - as they could in Twilight.
“Uh, Moon Dancer?” she asked tentatively, “I didn’t quite expect this to happen…”
“I’m… I’m a goo pony?” asked Moon Dancer, holding up her bendy hooves in front of her. She had a strange look of fascination on her face. Twilight was relieved to see that she didn’t seem to be scared or angry, but since they seemed to have shared their experience, Twilight knew that Moon Dancer was probably still riding the same high that she was.
Moon Dancer stood up and swayed her body back and forth, stifling a giggle as she felt the mass of goop that was her body bounce back and forth. It felt nothing short of amazing, but also tantalising. She felt like she needed to hold something, or someone, and feel her body mould around their shape.
“I can see how you felt now Twilight,” she said, “Like, like you have to hug someone, with as much of your body as you can!” She hugged her chest, straining until her legs disappeared into her body with a bloop, and then popped out from the shoulders again.
“Exactly!” said Twilight, relieved to hear that it wasn’t just her. “But we might have a problem now… we needed you to fix me… and I’m not sure if either of us can cast traditional magic right now…”
“Yes… we need to investigate this and put ourselves back to normal now…” agreed Moon Dancer, “But… maybe… could- could we hug again first?”
Twilight grinned and opened her forelegs invitingly. Moon Dancer trotted over to her and threw her hooves around her neck. If hugging Moon Dancer as a pony had felt amazing, having both of them be made of goo was on another level. Their bodies flowed around each other, battling to equalise in tension with each other, limbs and necks elongating to better wrap around one another.
Their mouths found one another and they kissed, tongues wrapping around each other in a manner quite beyond what ponies could normally achieve, tasting one another without the need to gasp for breath or avoid digging a hoof into a joint.
As a regular hug, it was hard to say if they actually succeeded, but they fell apart laughing with glee.
“Oh boy, we really messed up…” giggled Moon Dancer, “And I have no idea how we’re going to fix this…”
