Chapter

Tucked away in Twilight Sparkle's mansion-like house was a basement she'd converted into her personal laboratory. All her various apparatus were neatly placed, ready to be used; a task she assigned to her friends-turned-assistants, Moondancer and SourSweet. Her lab coat swept past her when she stalked beside a table lined with caged animals, rattling their prisons and filling the air with wild shrieks. “Easy now,” she murmured staring over her glasses. “We won't hurt you, I promise.”

Turning to look past pristine walls she'd lined with schematics, machinery she'd rigged up to simulate the magic mirror that enabled one access to Equestria was stationed nearby. “I'm not sure about this,” said Moondancer who cradled a black horn in her hands, dressed in a matching lab coat. “Are you sure we shouldn't return this? All we have to do is inform Sunset-”

“Don't be such a spoilsport!” SourSweet crossed her arms with a grumble then softened. “We can't run to her every time a problem comes up! It's only a changeling horn, right? How harmful can it be? Now hand it over!”

“Fine.” Moondancer passed the spire to their lead. “But I still think it's a bad idea. What, with all the people who've mysteriously turned into monsters lately? You can't tell me this doesn't involve Equestria somehow.”

“No arguments, you two. We're all in this together!” Having run the calculations dozens of times, then letting her assistants look them over, Twilight was confident their experiment would be a success. Rather than contain, or worse slay the poor victims who'd been transformed into savage monstrosities, they would discover a way to reverse the process!

Following her gestures the device was activated with a whir; it buzzed and crackled with electricity. She placed one of the cages before the machine, and the horn beside it, then stepped back, light's flashing over hers and Moondancer's spectacles.

The trio knew to keep their distance, just in case, and backed up; ready to see a fusion between the snake she'd selected and the changeling horn. The mix of science from here and magic from Equestria would then be reversed, and could hopefully be applied later on a grander scale; but for now she decided it best to keep this contained and controlled.

A myriad of colors whirled at dizzying speeds. The machinery shook and smoked, overloading. “Quick,” cried SourSweet who shielded herself with her arms, shrieking over the winds as her ponytail was tossed about. “Terminate the experiment!”

“I-I can't!” Moondancer threw the emergency switch repeatedly.

“Let me handle this!” Twilight marched through the magical gales, notes and equipment tossed about, vials and beakers shattering and filling the air with a mixture of odors. But at the moment her sole concern was taking responsibility for this. She pushed past them, hair and coat whirling about her, raising her arms and ducking her head to shield herself from debris.

Overloaded with the Equestrian magic it tapped into, the machine exploded with a deafening boom and a blinding flash of light. All three of them screamed, thrown from their feet, the air crackling with electricity and smoldering with the stench of fire and smoke. They scrambled, knocked onto their backs or butt, trying to find purchase in the ruins amidst their dizziness.

The downpour of magic that leaked through the rift left in the air seeped through the atmosphere.

“Wh-what the hell,” muttered SourSweet whose vision swam.

Smoke and dust began to dissipate. Small fires and sparks of electricity popped, and the overhead sprinklers finally kicked in, showering them in a deluge of cool water which left hisses in its wake. Twilight stared down at her half denuded, soot-covered form. “What's happened to me...?” She practically hissed out the words, eyes turning to slits.

Below her breast she was completely naked save for blackened, tattered remnants of her attire which clung to her. Under her bared vulva flesh gave way to serpentine skin, her tail which was marked with a colorful diamond pattern dragging behind her where legs once stood. To her horror, written on her face, she realized she had somehow fused with one of the specimens.

Moondancer gasped. “A...a lamia,” she whispered recalling the monster from a myth.

Twilight's skull throbbed. She whined and reached her hands to it, tried to focus her thoughts, her memories rapidly deteriorating. What remained of her humanity was being stripped away, overwhelmed by baser animal instincts.

She twitched her tail, shot out her forked tongue experimentally, slithered and left a slimy trail behind her. Her hands lowered to her breasts, cupping them with a squeeze, their once average size now multiplied with wide, stiff nipples. Looking over her shoulder she noticed her hips and buttocks were similarly blessed, bared like her vulva before terminating into snakeskin.

Her tongue encircled her areola, drawing circles around them and leaving a spit trail that sluiced down her curvature. Yet she still felt dissatisfied, and turned her attention elsewhere. When she looked upon her lab partners she no longer saw her friends. Indeed, a new, all-consuming hunger awakened in her belly, which escaped in a rumble that made her midsection shimmy.

Moondancer took a step backwards. “Twilight, wait! We're-”

Her shrill scream was cut short when Twilight snapped to her with such speeds it was impossible for a human eye to follow. Her tail repeatedly wrapped around her closest lab assistant, constricted her with what would have been bone-breaking force, yet she held back just enough not to harm her yet to where it was impossible for even a bodybuilder to escape.

Moondancer wiggled, sobbed, and begged, snot running out her nostrils, her glasses tilting off the bridge and landing with a snap below. Droplets continued to rain down on them, then abruptly stopped, and Twilight licked her prey's cheek. At the same time SourSweet stared, dumbfounded, too frightened to move as she soiled her panties with a stream of runny urine.

“Yesss,” mused Twilight with now glowing, crescent-shaped eyes. “You are ssstill ussseful to me~” She practically sang the words in a low, sensuous draw, hands tightening around Moondancer's head, forcing her to face her.

“You don't want to do this,” urged Moondancer in desperation, but whatever rationality Twilight once had was gone. Twilight nipped at her tits, made her cry out, peppering them in love bites that left red marks all over her pale flesh. Again-and-again, she nibbled and sucked, kneaded and pulled, stretching and twisting the soft milky orbs, threatening to rupture them.

“Oh-oh God,” cried the hapless assistant, burning with shame when her cunt churned, an orgasmic ripple spreading throughout her breasts and making her shamefully whimper in unwanted delight, clenching her twat and her butthole.

“Good little bitch,” murmured Twilight with a muffled coo, like she was coddling a child. “You want it, don't you?” Her tail tip teased her partner by slipping under her skirt and panties, rubbed circles around her squish cunt which she mashed against, flicked at her clitoris which peeked out, swollen and slick. “Just sssurender to me, and I'll give you eternal pleasssure.”

“I...I...” Moondancer's head swam, unable to deny it was the best thing she'd ever felt. Some depraved part of her wanted to submit, to become her living plaything, in return for the comfort and bliss she'd provide. “I'll do it!” She cried out the words, uncertain why she'd given in so easily, unaware of the pheromones clouding over her mind into submissiveness.

“Excellent!” Twilight planted another pair of kisses on her wide, perky nipples, biting on the pink nubs. She pressed her pouty lips over hers, licked them, shoved her tongue into her mouth and down her throat, her fangs injecting a potent venom.

“Mmph...!” Moondancer blubbered and tried to shake her head, forced to swallow the viscous substance down.

Forced to lock eyes, predator and prey became one as the toxins settled into Moondancer's belly with a gurgle. Eyes glazed over, unable to break Twilight's hypnotic stare, and the tail secreted its own oily substance. Clothing disintegrated under the fluids, yet she was unharmed, even the tuft of messy pubic hair on Moondancer's cunt dissolved under its touch.

Twilight licked out her prey's mouth, shoved her tongue down her gullet, claiming her completely. Moondancer moaned and leaned into it, whatever remained of her psyche shredded and twisted to suit her new master. “You're mine now.”

Flesh rippled and twisted with wet smacks. Bones cracked and shifted. Moondancer moaned, and Twilight withdrew with a pop, a string of saliva connecting their lips. Sparkle withdrew from her chattel, revealing a layer of scales that formed on Moondancer's legs, now sealing together and taking shape as a snake's tail. “Will I be like you, Twilight?”

“Yesss...but to complete our transssformation, we must feed.” She nodded at SourSweet.

SourSweet raised her hands before her with a nervous giggle. “C-come on, we're friends, right?” They started to slither towards her, Moondancer's new appendage settling into place, and SourSweet snarled. “You two are crazy! I'm outta here!”

She turned and tried to run towards the exit, only for her heel to slip on her piss puddle. With a yelp she practically flipped and winded herself with a thud. Instantly the lamias were upon her, yanking her to her feet by the arms.

“What do you sssay,” asked Twilight. “Burn away her clothes, or do it the old fassshioned way?”

Moondancer let her messy hair down from its bind, face breaking into a devilish grin. “How about this?” She seized Sour's blouse in a fist, ripped it open and the bra underneath in one motion, heavy freckled tits flopping out and smacking together.

“N-no!” Sour's breasts heaved and she panted and squirmed.

“Yesss.” Twilight's nails were now more like claws, and she dragged down the rest of Sweet's attire, skirt and stained panties pulled away to reveal a bald, tight pussy. “Deliciousss~” She hooked up her fingers, sinking a couple into her wet slit.

“A-ah...” Sour closed her eyes and moaned with a heavy blush, a trickle of blood and pussy juice seeping out her twat.

“Freckled here too,” noted Moondancer who studied the spots all over Sweet's blush-stained, pert buttocks.

“P-please...” Sweet whimpered and sobbed, unable to break their supernaturally strong hold. They dragged her, slithering over to an examination table, where they spread her limbs wide and secured them with binds.

Twilight had only ever intended to use this to protect a patient who might harm themselves, but it was perfect for experimentation! The serpents played with their meal, wrapping their tongues around Sweet's tits several times, almost crushing the soft flesh while their forked tips flicked and dabbed at her perky nipples. She squeaked louder, her cunt dripping down her ass curves onto her asshole, leaving the hot pink exit hole glistening with her feminine slime.

They inhaled the scent of her moist pussy, spread its tender walls open, exposed the sticky pink caverns. Her clit swelled from its hood, her urethra and cervix entrance left unveiled. Moondancer jabbed a couple digits into her, wet schlicks sounding as she rapidly pushed in-and-out, sending spatters of her feminine cream shooting out. The discharge pooled under her ass.

“St-stop,” begged a watery-eyed SourSweet, struggling before the sensuous yet nightmarish pair. “I'll kill you!”

Moondancer shook her head, now fully settled into her new form. “Unssstable bitch.”

The pair sunk between her open thighs, elongated tongues extended to assault her fuckholes as one. Twilight dragged circles around SourSweet's pussy, cleaning her sticky warm walls with a slurp, while Moondancer did the same to her asshole, the pair pushing in unbelievably deep. Sour shrieked, her cervix forced open and the slimy confines of her womb explored.

Wiggling and jiggling, SourSweet's cries mixed with her moans, her skin laced in a sheen of perspiration. She blushed so bright her freckles were nearly invisible, and her funholes reflexively squeezed down, crying when she arced her breast and hips upwards, shooting a spray of her feminine nectar down Twilight's throat which messily ran down her lips and chin.

Moondancer greedily slurped up the runny excess, the tangy flavor settling on her tongue. “Mmm...deliciousss.”

Twilight similar withdrew and licked the juices that glazed her lips. “Too bad we have to ssshare.” their stomachs rumbled, a reminder that if they weren't able to feed in time, they would revert back to mere human women.

On cue a knock sounded at the basement door. Twilight was thankful she hadn't soundproofed the lab this time. “Hello? It's Lemon Zest,” came the voice. “Hey, is everything okay in there?! There's a few smoke vapors leaking out!”

“Hold on,” called back Moondancer who attempted to sound normal as possible. She exchanged a nod with Twilight, who quickly clamped a hand over Sour's mouth, and Moondancer slithered up the stairs unlatching the door.

“Cool,” said Lemon Zest who marched in. She froze in place, seeing SourSweet writhing naked on the table with her mouth covered by lamia Twilight, but before she could react Moondancer's tail wrapped around her ankles and yanked her down. “Fuck!” Her head banged on a stair, dragged down the snake-slime stained stairs with repeated thuds.

Moondancer seized Lemon's ankles and hefted her upside-down, spreading her legs wide open. Her blouse drooped down to expose a lacy bra containing a smallish but perky pair of tits, her pleated skirt flipped to reveal a similar pair of panties that clung to her toned hips, ass, and pussy. “A sssweet meal for both of usss.”

“What's up with you freaks?!” Lemon Zest snarled and tried to wiggle free, but was held fast, head starting to swim from her current position. “A-ah-!” The serpent's tongue lapped over the visible labia through her panties, left a spit trail that mixed with the juices that started to freely flow. “You're not really gonna-!” She tensed up, the fabric torn when the tongue's tip shot into her. It wormed into her pink tunnel, explored its spreading walls, pushing deeper and deeper without relent.

She was mercilessly tongue-fucked, sharp fangs ripping away the rest of her underwear, the slimy muscle shooting in and out with rapidity. Cunt musk filled the air, Lemon's twat secretions dripping down her curves, over her barely contained breasts, making her gurgle when it slid into Lemon's mouth. “Gl-gluh~!” She was forced to swallow down her tangy lust.

Unsatisfied with simply watching, Twilight slipped over, dug her claws into Lemon's top and upraised skirt, shredding them and the bra away to leave her bared. “Happy to help,” she said then wandered back to her own hapless treat. “I have an idea.”

Moondancer listened, still focused on her exploration, tongue so buried it distended Lemon's belly while she claimed her slime-drenched womb. Zest's tits swayed each time she struggled in her grasp, more trails of her feminine goo dribbling down her curvature and into her glazed lips. At the same time Twilight undid the binds around Sour's ankles, laughing when she kicked at her. She seized her prey by the ankles, lifted her spread legs up so that they were around the girl's head, ass upraised.

“I sssee!” Moondancer grinned and let Lemon's head hit the floor with another thump. She raised her own tail tip, like her mentor using it to tease at her meal's tight orifices. “Ssshould I fuck your pussy? Or your asss?”

SourSweet cried, “How about neither?! Just let us go, and-”

The lamias took aimed and impaled them at the same time with one brutal thrust. Their cunts were forced wide opened, seizing around them, buried womb deep, bellies rounded and filled to the brim. Shrieks turned to moans, Twilight and Moondancer fucking their fleshy toys in unison, their palms encircling tits and asscheeks, groping and smacking them raw.

Wet slaps filled the air. Twat spatters splashed over them. Their fuckholes reflexively clenched around their intruders, faces sweaty and flushed, eyes hazy and mouths opened in a dulled manner. Both predators pressed their lips to their fucktoys, tasted them in a sloppy kiss, left small red scratches over their breasts and buttocks while they crawled at the supple flesh.

They lost track of the times their prey were forced into messy orgasms. And when they grew bored, both switched partners, and repeated the process. Twilight reminded herself they were ultimately disposable, that there were more Shadowbolts to sate themselves on, but as for her own circle of friends? Well, she preferred to convert them, too! To make them perfect like her!

“N-no more,” whimpered Sour who was slack, fucked into an addled stupor, ponytail loosened to a tussled, sweaty mess.

“I'm so sensitive,” whined Lemon through tears. “It feels like someone took a jackhammer to my insides!”

Twilight undid the bands around her meal's wrists and flipped her over. She licked her lips and stared at the freckled, feminine lube-slicked ass, tried to decide whether she should rape her some more of finally quell her boundless hunger.

Toying with them some more, the lamias slurped at their sexholes, digging all the way in, making sure to drink up every last drop that tickled their now more sensitive tongues, able to appreciate each subtle taste and scent of their musk and womanhoods. Their prey swayed, wincing each time the serpents nipped at them, teasing their breasts in particular nips with dripping, venomous fangs that dribbled down their curves, threatening to break the skin and end their lives with a flood of toxins. Sucking on Sour's clit and tickling her g-spot, she screamed and came directly into Twilight's throat.

Gushes overran Twilight's mouth, down her gullet, washed over her lips and chin. She dragged her tongue over the contours of her mouth, drinking up every drop, savoring its tang. Her slave was still quaking, and she tightened her hold, her tail threatening to crush her bones. Sour slackened further, face starting to turn purple, fighting to draw breath.

Not to be outdone, Moondancer raised her tail, spun Lemon so that she faced her, and held her upper arms, impaling her on her tail tip. Zest yelped, stomach bulging, her innards reshaped to take her phallus-like extension, yet it was also curvy and feminine, mist and warm. Roughly she fucked her, slamming her down with gritted teeth and a hiss.

“It...it hurts,” whined Lemon through tears, her face flushed and her pussy clamping down, dripping over her rapist.

“You're ssso tight~” Moondancer dragged her up and down, driving into her uterus, filling it like she was a living nest. Her maw opened impossibly wide, bones shifting allow her mouth to stretch, which resembled an incredibly wet pink birth canal. She wrapped her jaws around Lemon's head, prepared to ingest her, enjoying the feel of her struggling, helpless.

“Lemon Zest!” SourSweet screamed for her friend, thrashed about, only to be taken by Twilight in a similar manner. “N-no...” Darkness enshrouded her when the maw closed down, emptying her bladder again in renewed horror.

Gradually the lamias swallowed down their food, throats distended while they were dragged, still being tail-fucked all the while with wet squishes. Their tails pushed their wiggling, kicking legs down, plush buttocks sliding over the moist roofs of their mouths. By the time they settled into the serpentine tummies, their flesh was distended out like they were heavily pregnant, giving them a new sexual thrill feeling their insides churn, so full as they completed their metamorphosis.

Twilight and Moondancer slid up to each other, pressed their bared bellies and breasts together, linking their tails while they embraced and shared a passionate kiss. Tongues wrestled playfully, both satisfied, knowing it would take excruciating hours before the Shadowbolts were digested. Their snake bodies burned all the while, getting an amorous pleasure from the act.

Each time the girls tried to escaped, trapped within their stomachs in a fetal position like they were babies in the womb, a mini orgasms rippled though the serpents who trickled out more juices and left them moaning.

Yet there was a whole world out there, waiting for them. First they would convert their friends and family, then spread out further, feeding on the rest of the Shadowbolts, their enemies, and anyone else who they deemed unnecessary or unworthy.
