Part 1 of 4 - Sylvia the Spontaneous Shewolf

This story is based on a very old comic drawn by FalyneVarger. A copy is here on DA: https://falynevarger.deviantart.com/art/Werewolf-Trans-1-2-163420604

She is an amazing artist and deserves your support! This is my extremely dirty story to accompany it, changing the anatomy a bit to fit a more sexualized version. Consider this a story for pages 1 through 5. FalyneVarger has given me permission to play with this comic. :D

Sylvia was twenty-five, and she had no history of lycanthropy, curses, or run-ins with feral wolves. She didn't wear any special necklaces. Nobody fed her anything. No strange rings arrived in the mail. She didn't wear odd furs or drink from the pawprint of a wolf.

Middleton High School hired her to teach French. She had no known reason to be a werewolf.

A little after sunset in late October, she was walking down the hallway outside the gym, past two of the lovely young cheerleaders, Gwen and Kate, when the full moon rose. A wave of pain flashed over her body. A clutch of recently graded papers fell from her hands.

Then the pain turned to simple, horrible pressure.

Sylvia was five feet tall, blonde, and rather busty. She wore rimless, half-moon glasses and put her hair up in a messy bun with jade pins. She wore pink gloss on her pouty lips. Her hips were broad. Her waist was thin and her stomach flat. Her ass was round. Her breasts were C-cup and broad. Her face was dainty. She was small and sexy and genuinely pretty...

And all of her beauty and humanity was instantly confining.

Sylvia saw the students looking at her. She must've made a sound, some squeak of sudden upset or moan of surprise. They were eighteen years old, ridiculously young and beautiful, and they barely even realized it.

One of them was an Asian girl, probably Korean, so skinny and small, maybe 90 pounds wet. If it wasn't for her perky, pouty little breasts, she might've been mistaken for someone even younger. That was Gwen. She wore a tight shirt that bared her belly and a skirt so short that it defined her ass more than it covered her. She probably didn't even wear a bra.

Sylvia licked her lips, looking at that hot little woman's breasts.

The other girl was a slightly taller blonde, more full and adult, with huge breasts--bigger than Sylvia's--and a fat fuckable ass in black volleyball shorts. Whenever she bent over, she sold onlookers on the erotic benefits of squats. That was Kate. Even her long, loose shirts were filled out to the point that gazes lingered on her chest.

Sylvia wanted to grab her waist from behind and hump her big butt.

But before Sylvia could act on these sudden, abrupt lesbian urges, she had to take care of this ridiculous, almost rage-inducing pressure. Her clothes must be on too tight--yes, that's what it was. She just--ugh--she shrugged her shoulders and grabbed the hem of her t-shirt, right at the bottom of the v-cut that bared her cleavage. Her breasts were painfully tight. It was hard to breathe! She just had to be... free!

With a rip of cloth, right in front of the sexy little schoolgirls, Sylvia tore her shirt in half, gasping loudly as her breasts spilled out of her shirt, only to find her tits straining against her black bra. Her breasts felt larger, heavier, and painfully hornier. Her nipples were screaming like tiny sensitive erections, chafing beneath the cloth. Why did Gwen and Kate have to be so hot? They made the pain so much worse! Sylvia could barely stand the way they gawked at her chest!

She growled and whipped her head to the side, slinging off her glasses. They struck the floor and cracked, and the students stared at them, shocked. Gwen checked the gym door at the end of the hall. Locked. They were pinned there, cornered by their half-naked teacher. To run away would mean running past her, and they were too scared to risk it yet.

Sylvia could feel her teeth sharpening, growing, filling up her mouth. Fangs pressed on the inside of her lips. She peeled her shirt off her body, dropping its tattered remains down around her legs. She grabbed her jeans and yanked at the waistband, snapping off the button and pulling the zipper open. Then she peeled her pants off her hips like they were on fire. Shoes were kicked away.

But the pressure, dear God, the horrible pressure remained. It was as if her bra and her panties were squeezing Sylvia so hard that the blood couldn't flow. She felt immense gay arousal thundering in her clit, like bolts of lesbian lightning shooting up her vagina and squeezing on her inner genitals. She felt her massive tits literally swelling, spilling further and further over the increasingly brutal constraints of her bra. She felt her spine squeezing and pulling, and it felt as if her asshole was filling with explosive sapphic lust.

Sylvia scrabbled wildly at her bra, yanking down the cups. Huge, veiny, swollen nipples flopped into the cold air, dripping with sweat. Milk dribbled from their distended, stretching tips. They were so aroused. They hurt so much! She had to do something about those erect titties!

Sylvia pulled off her bra, threw it on the ground, and grabbed her breasts violently, squeezing massive handfuls of her aching, swollen boobs in her clawlike grasp. Then screaming hatefully, she tore at her tits, and with wet, meaty yanks, she ripped off her human nipples.

The schoolgirls screamed with terror. Their teacher was cumming apart!

Each tit cummed brutally. Human areola peeled away in Slyvia's fingers, revealing gigantic, black nipples underneath--puffy, thick, and erect. She cried out with relief and orgasm, cumming from the monstrous tits beneath her skin. Twin jets of milk gushed out of her nipples and sprayed onto the floor. She kept clawing at her human breasts, splitting thin, taut white skin. Huge breasts with walnut-dark fur puffed through the gaps, spilling wetly out of her shredding chest.

Finally, growing frustrated with the remaining skin, she reached deep into her growing cleavage, took hold of the strip of skin across her sternum, and yanked at it like a handle. The last bits of humanity of on her chest tore away, and her gigantic furry breasts fell into place, the pair resting in front of her with impossible firmness. Each was bigger than her head. Dark nipples still milked. Shocks of orgasm still shuddered through her giant, horny titties.

Relief was pounding in her unveiled, furry flesh. She'd finally found a path out of this pain and into indescribable pleasure. Her reward was literally bursting out of her skin!

Another wave of growing pressure and pain surged in her back, her face, her ass, and her pussy. Fingers and hands shuddered and cracked. Milk dribbled from her jiggling breasts. Sylvia fell to her hands and knees in front of the girls, still wearing her black panties. She shook her body eagerly like a dog on all fours, feeling her flesh swell and shift beneath her skin. Then she threw back her head and felt her hairpins tumble from her head. Blonde hair spilled from her aching scalp. Her new beastly breasts hung heavy beneath her. She groaned.

She scraped at the floor with hands and feet, and the sensitive tips of her fingers and toes split open, unleashing long, scything claws. Linoleum gouged joyously as her shaking hands burst open, skin coming off like overfilled gloves. Dainty human hands were shedding off large, walnut-furred paws with black palms. Old pink fingernails hung uselessly from the tattered skin. Her feet peeled open like broken stockings. Longer, lupine feet stretched into shape.

Sylvia threw her head up and stared at the schoolgirls before her. They were so beautiful, so arousing. That thundering feeling in her pussy and ass, that pounding pressure wrapped up in her teeny-tiny black panties--fuck! Her inner genitals were transforming into something lesbian, throbbing just within her straight human cunt.

Instinct commanded her to push with her vaginal muscles, to unleash the beast through her horny cunt, but that only made the pressure worse! Her shaved pussy mound began to bulge as her inner genitals untucked themselves from deep within her groin. She felt her inner clitoral tissue merging, shifting and expanding down away from her human clit. She felt a throbbing tube of orgasmic meat inside her pussy, a growing inner clitoris curling down beneath her labia, blocking off her vaginal canal. She felt her canal filling with a pair of descending masses. Muscles were shifting in her groin. Pressure and pain rose. Her knees shook.

Then her spine snapped loudly, shifting again, and deep within her round wide ass, up between those strong buttocks, the animal within readied herself to be born, and Sylvia embraced that horrendous birth. She pushed her big, beautiful ass up into the air. She lowered her big milky breasts to the floor, bending over as far as she could manage. The tiny panties, still trapped on her hips, slid down a bit, revealing the tiniest portion of her crack. Then, clenching her jaw, she squeezed to push a raging werewolf out of her butthole!

Her sphincter tented over the inner beast, once, twice, thrice--then with a scream of joy and pain, her tender asshole blossomed, and four inches of stiff, walnut-furred wolf tail erupted out of her cumming ass, instantly tenting her tight black panties. She clawed the floor, wriggling her hips and making her buttocks slap together. It was the most intense anal sex she'd ever felt. She was being buttfucked by the animal within. Her tail was fucking her human asshole. She was being reborn through her filthy little hole, one inch at a time!

She screamed again and another three inches of tail tore through her white-hot sphincter. The strength of the wolf's tail was immense, pressing at the top of her asshole with enough pressure to draw her sphincter taut, nearly to breaking.

Her panties, pulling up into her swollen pussy mound, finally could no longer hold. They snapped down off her tail, bunching over her increasingly distended snatch. The waistband stretched over her growing muscular thighs. Her asshole was bared, with a werewolf's tail sticking out of her butthole like a flagpole buried between her buttocks.

She stared at the girls with lesbian lust, and this time, she howled!

The schoolgirls screamed again, now grasping the true nature of Sylvia's transformation, but their terror only fed her lust and rage. Pressure surged, filling her ass to the brim from within. It was time to push more out! Sylvia strained reflexively, slowly birthing more tail in slimy jerks, each inch of wolf thickness leading to a wave of assgasm. The monster within no longer fit in her skin. She was cumming out of her anus because she was growing too big for her humanity!

Anal orgasms surged sympathetically through her pussy bulge. Her vaginal canal was now packed painfully full and tight with two hot, aching masses. Her clitoral tube was growing denser and girthier. A head of flesh was forming somewhere at the bottom of her pussy mound, right at her taint, reshaped by buttgasm after buttgasm of transformative anal sex!

Yes, yes, Sylvia thought, I understand now! I'm a werewolf! I'm a monster, and I'm destroying my human self from within. Now watch, girls! Watch my ass burst!

The werewolf's tail continued to rip out of her asshole. She grabbed her buttocks and spread them, shouting wordlessly, encouraging the end of her straight ass. Three feet had grown out of her anus. The tail was becoming too thick and far too strong. By now, it was tracing a visible bulge from the top of her rump, down between her buttocks, and out to her asshole--a line showing that it'd grown all along from its proper place on her back. Her sphincter was stretched almost two whole inches up, an oval of white hot asshole hooked over that straining monster's tail. She was shaking her rear and summoning the strength to destroy her asshole!

Here it comes! Anal birth! I'm cumming! Oh God, goodbye butthole! Hello wolf!

She clenched every muscle she could, bending over as much as possible, and she annihilated her asshole to give butt birth to her beast!

With a loud meaty tear, her tail tore through the top of her asshole, sending her into convulsive fits of blinding assgasm. Her veiny, throbbing snatch squirted into her panties, followed instantly by inner genital flesh surging and squeezing. Her two aching masses pressed into the clitoral tube blocking off her canal. Her meaty tube began to swell and pound beneath her pussy lips.

Her tail whipped up through her ass crack, sundering her milky skin straight up to the top of her rump--and then her big, furry, dark buttocks began pushing out of the wreckage of her cumming asshole, her entire rear pulsing to the relief of her tail being forced out of her butt.

But the transformation wasn't ending! Anal birth was destroying the last of human Sylvia beneath her skin. An assgasm surged up through her body, through her milking tits, out into her throbbing limbs. Everything swelled with strength and power. The tears on her hands and feet began to climb in long, slow lines along her arms and legs, with fur puffing through the gaps as her flesh peeled open. Even her face cummed with buttgasm, and she could feel nasty cracks as her nose and jaw began to thrust towards her open mouth, pushing her lips even further apart and baring her massive, slavering fangs to the open air.

But most grotesquely, her assgasm made her human pussy hurt more and more with every passing second, until the pressure and pain were growing so immense that they nearly rivalled the pleasure of her transformation. Her tail stood on end.

Sylvia thought she'd understood what she was becoming, but this thing inside her vagina was something new. This was something deeply feminine, deeply lesbian, and deeply monstrous.

Her pussy hurt so much. She wanted to destroy her snatch. She rose onto her knees and grabbed her hair with her claws, getting a solid grip down near the scalp. She wanted to destroy everything so she could be free to fuck the living hell out of these beautiful school girls!

Sylvia spread her legs and squeezed her vaginal muscles again, and this time, her groin muscles shifted with an audible slorch of flesh. She bayed with pain, and that giant, girly pair pushed out of her vaginal canal and into the space beneath her horny pussy lips, shoving the meat tube tight against the inside of her tiny human vagina. Her straight pussy lips were instantly filled by the beast's true genitals, packing the itty-bitty crotch of her black girly panties with throbbing, aching pussy mound. Instantly, her massive shaved cunt was edging on orgasm. Her labia were distended, veiny and pale, spreading apart over the hefty girl within. Dark, bulging flesh peeked out of her all too tiny vagina. Gwen and Kate could see the gates of her human sexuality, strained to their limits. They could see her pussy lips, ready to cum to shreds!

And here, on the edge of orgasm, her face cracked one final time. Ears stretched and strained within their skins. Nose and mouth merged beneath the mask of her face, becoming a muzzle behind her lips. She grimaced, shutting her eyes tight and squeezing her mouth closed, and she started pulling on her hair as hard as she could. With a gross series of pops, the monster beneath beautiful, effeminate Sylvia surged into her lips, her nose, and her brow. And slowly, with disgusting tension, Sylvia's face was distorted, stretched and tented over the clear shape of a werewolf's head, threatening to destroy that grimacing girl.

"No, no, no..." whispered Gwen, begging Sylvia to hold it together, to hold it all in!

Spitefully Sylvia squeezed again to empty her cunt, to give birth to her true self, and her pussy lips spread one final time. The lesbian werewolf crowned the human's hetero vagina. She grabbed those fistfuls of hair tighter, yanked harder. Everything hurt beyond imagining, but coitus and relief were almost there. Goodbye humanity! Goodbye pussy!

Sylvia the French teacher was ready for a life-ending orgasm, and in that moment of pure acceptance, human Sylvia ended.

With immense werewolf strength, the beast ripped Sylvia's head in half. Pulled by her fistfuls of blonde hair, her scalp burst apart. Her lips snapped in the middle. Her nose burst open. Her brow cracked in half. And with wet, sticky yanks and the loud sounds of tearing skin, the werewolf forced her furry head through Sylvia's sundered face and scalp, destroying them utterly, and the halves of Sylvia's head were peeled off the walnut-furred werewolf, howling--

And in that moment of annihilation, her bulging labia blossomed, spreading beyond their limits. Her inner lips parted over the crowning monster. The pink of the vestibule--the flesh around her vagina--stretched to translucency over a straining serpent of black, veiny flesh. The tube of girl meat was tucked down between her legs, curled over the contents of her bulging snatch. Then her vagina gave up the ghost, and with the immense wet noise of her lovely genitals tearing in half, her sweating pussy suffered the most massive orgasm Sylvia had ever felt.

Gwen and Kate screamed in horror!

Sylvia's orgasm exploded out of her tiny, girly cunt, starting the pussy-bursting birth of the lesbian werewolf's gigantic black cock and humongous furry balls! The mass of her shewolf genitals surged. The terrible pressure of her instantly swelling erection forced her labia apart and tore her vagina down through her taint and through to the bottom of her butthole, connecting her anal rebirth to her vaginal rebirth. Waves of orgasm wracked her body, making her howl endlessly with pussy's end. Her massive slimy dick untucked from between her thighs, whipping her tasty penis into the black crotch of her panties, where it was caught half-erect and straining. Her clitoris screamed with joy, stretched over her turgid shaft. She squatted harder, pushing more ass and genitals through the tear in her human rear. With a satisfying smack of flesh flying free, her apple-sized werewolf balls burst from her parting pussy lips and flopped onto her big gay dick. Her heavy lesbian scrotum overflowed the crotch of her panties, completely filling up her gorgeous thigh gap with aching nuts.

Then her boner grew too hard for even those panties to hold, and the cotton bands around her hips tore away. Her immense cock swelled instantly to full erection, sundering the rest of her pussy with the sudden upswing of her girthy weiner, annihilating her little human clit with a final pussygasm. Sylvia's howl broke, becoming a sheer roar of joy. Her walnut-furred balls flopped beneath her, and that final pussygasm surged through her aching newborn testicles, squeezed her throbbing prostate, arced up through the base of her monster cock, surged up her full, arm-thick erection, erupted into the fist-sized cockhead jutting lewdly out of her wet foreskin--and then Sylvia's foot long werewolf cock cummed!

Thick long arcs of hot girl jizz shot into the air between the shewolf and the school girls, painting the floor, her breasts, and even striking a white line of semen across Gwen's shoes. Her cummy erection bounced up and down, hot balls flopping and sexy girl dong whipping through the air. While emptying her massive balls, her erect nipples took their cue and unleashed the pressure within. Hot milk sprayed in streams from her breasts, adding to the mess of white, sticky fluids that rained down onto the tiles. Some sprayed over Sylvia's own dick, running and dripping in white rivulets down her black pillar. Her nipples simply cummed as long as her dick cummed, a cycle of orgasm that shook her from her fat tits own down to her fat weiner and back again.

Her howls and roars died away. Finally, she grabbed hold of her cock by the base and tried to aim it up between her milking breasts, spurting the last little bit of cum towards her own face so she might taste her cum and know she had been reborn. Salty-sweet jizz sprinkled on her dark muzzle but mostly splashed on her tits while she lapped the air and sampled her own semen.

The newborn werewolf Sylvia rose to her feet then, her erection untamed by blowing her load. The ruins of her human head lay collapsed across her broad shoulders. Where her clit had stood, her dick now rooted. Where her labia had been, now her nutsack hung heavy. Her straight human pussy was gone completely, everted into the gay cock and balls of the beast.

In a sense, she was still Sylvia. Her memories were her own. But her personality had been replaced entirely by the monster that'd grown underneath her skin. She had a new, beastly lesbian identity, and she planned to fuck the shit out of these young women with her humongous newborn dick--but only after they had come around to her point of view!

Quietly, she hooked the remaining human flesh at her throat and sliced open the band of skin between her lupine head and her bare werewolf bosom. Using a hand, she peeled back each shoulder like removing a tight latex dress, pale rubbery skin tearing and slipping wetly off her walnut-colored fur. Then she took a single claw, hooked the skin below her breasts, and unzipped her flesh in the shadow of her werewolf dick, slicing down to the top of her old pussy mound. Her bunched and wrecked labia ringed the broad base of her cock and balls, with the bottom of it becoming loose about her naked ass and hips. She pulled back the skin on her belly, peeling off the skin where it was stuck to her back, and all the humanity that'd fallen of her shoulders and arms flopped wetly down around her hips and thighs.

Then, like a pair of pants that'd already been dropped below her genitals, Sylvia popped the skin off each hip and dropped it down onto the floor. Gravity peeled the remaining tatters off her forearms, thighs, and calves. In a circle around the feet of a naked, horny shewolf, there was the empty, collapsed flesh of a destroyed human girl, out of which she'd burst violently and orgasmically, for no apparent reason at all. The full moon had changed her forever.

Sylvia the shewolf was stronger and more muscular. Five feet of woman had expanded to five and a half feet of werewolf. Every limb strained with the potential to leap and bound. Grace defined her lithe, skinny form. Her muzzle was long and refined. Her ears were tall and sharp. Her eyes were gold and glittering in the dim hallway lights. She could smell ass, pussy, cock, milk, and cum. She could smell the fear of Gwen and Kate.

But most importantly, now that the human was a torn and empty pile of skin, Sylvia felt pangs of relief blending with aftershocks of orgasm, and she felt so perfectly dominant, sexual, and female. Her breasts were immense and fertile, ready with sweet hot milk. Her hips were even broader and her ass was gigantic, strong, and deep. Her werewolf asshole was sensitive and her tender prostate ached to be milked. And below that fine feminine butt, hanging in complete view, there were her big sexy balls in a soft furry sack. She must look like the most incredibly buttfuckable woman, ready for an asshole full of cock and a reach-around.

That's not what Gwen and Kate saw though. They saw the thing that made Sylvia feel like a mighty queen. She had a baseball bat of hard black girl cock standing tall over her belly and nearly touching her breasts, dripping with cum and milk, proving with every inch that she was eager and able to give them the lesbian dicking of a lifetime.

Sylvia took one step forward, her cock swaying with the swinging of her wide hips.

Kate and Gwen bolted to the right side of the hallway, where there was only a touch more room between the werewolf and the wall. Sylvia lunged half-heartedly. She easily could have tackled them both, but it wasn't necessary. Gwen was being dragged by Kate, and she lagged behind long enough to be reached. Sylvia landed on all fours and swiped out gently with one claw, drawing blood across the front of one bare thigh just within Gwen's flowing skirt. The girl probably didn't even feel it. The cut was so smooth.

Then the screaming school girls found the end of the hall and bolted through the exit, charging straight for the woods to the west of the school.

Sylvia smiled, a small twist of her black werewolf lips, and she tugged on her cock to keep it hard. If Gwen was anything like her, there were only minutes left in her humanity. Sylvia would find her in the woods soon--if legends were true.
