(F to Tiger)

“Stupid idiot,” Josie grumbled, an uncharacteristic frown on her face. The blonde crinkled her nose as her foot stepped into something unmentionable, and she resolved herself to using Daddy’s money to buy herself a new pair of shoes.

“I mean, what’s so special about a zoo anyways? Why did that dumb guard say that I needed to be older to get into these exhibits?” Josie’s thoughts buzzed with ire and aggravation alike. “I’m an adult,” she paused, “technically.”

Little did she know, that she should have heeded the guard’s warning. As she walked into the exhibit, subtle changes began to make themselves apparent along her body. Small lines traced their way along her young skin, like cracks forming along ice. Around these lines, her skin began to darken and smooth to a rich shade of green.

A brief headache overcame her, and she squeezed her eyes shut. When she opened them again, they were gold and supported vertical slits. “Ssssomething’s wrong,” she muttered. The girl’s tongue flicked from her mouth, twice as long as it had been before and with a bifurcated tip.

Her gait slowed, and she looked to the trees around her. The green leaves looked strangely welcoming, and for some reason she wanted to press herself against, curling around a branch, looking for prey, awaiting a mate…

Josie shook her head, clearing her thoughts. It was then that a small bump began to protrude from her backside. As she remained still, contemplating what to do next, the nub grew. It started inches at a time, then soon began to grow a foot every few seconds, until it curled around her leg.

She looked down with aggravation, only to squeal in surprise at the site of a snake’s tail wrapped around her jeans. “Get off me!” She cried, falling backwards and bruising her tailbone. With the motion, her tail dislodged from her calf, shaking before her startled eyes.

It rattled. She could feel it rattle. Her eyes widened as she realized the tail was a part of her; she had somehow grown a rattlesnake’s tail. “No way…” She breathed, a faint flush crossing her cheeks. Though she’d never admit it, the girl always expressed a private interest in lamia and other such monster-girls. The thought that she was turning into one was… Intoxicating.

She curled her new tail, trailing her fingers along its smooth scales and gasping with quiet surprise as she felt her digits upon her own snake flesh. As she did, her legs began to shrink and her tail repositioned itself to the lower side of her body. Josie watched her shoes fall from feet that were no longer there, a smile slowly working its way across her face.

“This is so rad,” Josie smiled and revealed a set of lengthening canines, “I can’t believe that this is actually happening…” She trailed off, at a loss. She looked down to her legs, and watched her pants slip off the new snake’s coil that served as the lower half of her body.

“Guess I’ll need to get better at bellydancing,” she said, curling her tail beneath her and slowly rising. She wobbled a bit, then lifted her arms above her head, practicing a few gyrations of her hips. Then her arms fell limply to her sides, and she began to acutely realize something was very wrong.

“That is to say, if I can make my stupid arms work.” Josie scowled down to her fingers in time to see them wither away. She let out a quiet gasp, jerking her head back, and golden strands fell onto her shrinking, outstretched arm. It took her a moment to realize the strands were her own hair.

“Wait, why isn’t it stopping? WHY ISN’T IT SSSSTOPPING?” Josie began to hyperventilate, her tongue flicking from her mouth more and more frequently. “I DON’T WANT TO BE SSSSOME SNNNRRRKSSSSS!” Her words cut off as her throat tightened, stealing away her ability to speak. She pawed with the nubs of her elbows towards her throat even as her neck stretched away from her body.

Your yellow eyes were wide as they swept towards the sides of her head, and she crossed them to see the bridge of her nose flare out occupying much of her vision. She felt something land on her tail, a clump of fabric. She realized after a moment’s shock that it was her shirt, having fallen from a body that no longer had shoulders. Her breasts receded into her chest, and she fell onto the flat tube of her body, hissing in distress.

I don’t want this, I don’t want to be a snake! Josie thought frantically, noticing a strange shimmering before herself. Her tail rattled curiously, and her golden eyes struggled to make out details of the haze. It looked much like the forest she was in, except the trees were different. These looked more like pine then the foreign foliage around herself currently.

Josie didn’t know what it was, and that gave her hope. She tried to ignore how natural was to move her serpentine body towards the portal, her long and reptilian form easily coiling and gliding towards and then through it.

Leaves and sticks brushed against her bare nipples and the girl squeaked in surprise. “What the-“ Josie’s eyes widened as she realized she was human again, albeit without any of her old clothing. She spun back behind herself to find the haze had vanished as though it had never been.

“Okay… That was weird.” Josie trailed her fingers through her hair, shuddering with visible relief. The motion jiggled her breasts faintly… As well as her gently swelling stomach. Already she was beginning to change, still unknowing of the danger she’d put herself in.

Rather than looking for an escape, Josie was too busy focusing on celebrating her renewed human form. She stroked her slender arms, pet her curvy hips, and then pat her belly as it rumbled loudly. “Well, I guess stress will do that to you,” she chuckled weakly.

Her nose visibly twitched as she instinctively latched on to the scent of food. Before she knew what she was doing, she began to move towards the intoxicating scent, her eyelids fluttering. The blonde girl’s hands and feet swelled, palms and soles growing coarser and puffing out into pads. Her fingers bulged as well and her nails encompassed the tips of her changing digits.

Josie reached the source of the smell in no time, reaching her transformed hand towards a beehive. She barely noticed the claw that her index finger had once been, instead fixated on using it to trail along the underside of the hive and draw a bead of honey. A smile spread across her features, even as her upper lip swelled into a particularly ursine cleft, and she stuck her finger past her black and rubbery lips with undisguised relish.

“Delicious,” she smiled vacantly, only to squeaked as she realized the danger she put herself in. “Wait, what am I doing? Without my hide, I’ll get stung all over!” She realized the ludicrousness of what she’d said a second later, by then realizing that she’d begun to change again.

She also realized that this time she’d missed the first signs of change.

Cold dread spread across her swelling gut, and she took another lumbering step backwards. Her wet nose snuffled at the air, and thick and shaggy brown fur erupted across her entire body. “Rrrghy dunwannrrrgh change!” She growled.

Like it or not, she could do nothing to fight it. Her tongue swelled in her mouth, causing her cheeks to bulge in a cartoonish fashion. Tears dewed at her eyes, and her rounding ears drooped. Then, a shimmer came to her left. She practically threw herself into this next portal, her shaggy body blooming fully into the form of a grizzly before landing as a girl.

She splashed into a warm and foul sludge, and a whimper of distaste left her lips. It was followed by retching, as she realized that by whimpering she’d accidentally swallowed some of the swamp she found herself in.

Her back arched, knobbly scales slowly pushing out from herself as her skin darkened once more. She hissed once more, baring her teeth to show her aggravation. “I don’t get it, why do I keep turning into… into…”

The warmth of her surrounding mock dimmed her mind and she fell onto her belly with a low rumble of approval. “This is more like it. This the vacation was looking for.” She didn’t realize that her thoughts were slowing; she didn’t realize that her form was changing.

Her arms and legs bulked up with incredible amounts of muscle, but grew shorter at the same time. Had she not been on her belly, she would have looked ridiculous. Instead, her body resembled a predator’s—more than a predator’s. She looked like a crocodile.

Josie flexed her jaw, watching with a smirk as her teeth forced her weak mouth open. She knew that new muscles would come in before long, giving her the bite strengths she needed to tear the gazelles apart. The weak prey would learn to enter her watering hole. They would learn the consequences of facing an apex predator.

Coarse, brown-green, and ugly scales carpeted her form like a tank’s plating. Her back violently wrenched as it straightened out, and she thrashed a tail she hadn’t even noticed grow. Flapping wings echoed the sound of her outburst, and she proudly hissed at having scared off the nearby waterfowl.

Her skull stretched and shrank at the same time, growing more and more room for a cavernous maw at the expense of what had once housed a human brain. Josie didn’t notice, Josie didn’t care, Josie was hungry. That was all that mattered.

Something glimmered to her left, and the crocodile darted her head towards it, seeing a familiar shimmering. Something about it triggered a feeding part of her mind, and she instinctively swim towards it, passing through it.

Plus, human lips pulled back to bare a young adult’s teeth, and the blonde hissed in confusion. “This isn’t right, where am I, where’s my swamp?” Josie blinked as she heard her own words, and it took her brain a second to return to focus.

It took her body even less time to begin to change once more. Once again, the petite girl began to swell. Unlike before, her form held no trace of muscle. Rather, it looked like she was growing fatter and wider. “Oh no. Oh no no no…”

Now that she was aware was coming, Josie could feel her head begin to fog over. She gritted her teeth, falling onto her knees and sending a jiggle through her fattening thighs. Her massive ass trembled like gelatin in the face of an earthquake, and she pressed the thick stumps of her hands to the sides of her head.

“Don’t want this… Don’t want change…” Josie grumbled, her ear flicking slightly. “Wannarghh… Grrhhuhhh…” Her heart sank, as she realized there was nothing she could do about this. One way or another, the transformation would have its way with her body.

She leaned her head back, opening her mouth to wail her displeasure. “GRRROOOUUGH!” Her mouth continued to open, opening and opening and opening until it was wider than her head was tall. A thick, goofy muzzle first from her slender face. Blunt but dangerous teeth lined this new maw.

She closed her mouth with a loud pop, recognizing it for the snout of a hippo. She didn’t even need her darkening skin to tell that. Something about it just felt right. A small tail wiggled above her fat butt, and she looked down to see a massively blubbery backside.

“NOOUGH!” She thundered, clumsily beating the sides of her head with her useless forelegs. “NUUGH HUPPOUGHHH! NUH! OOUURRMANN!” She babbled like a mindless idiot, unaware as to the consequences of her futile struggles.

The angrier she got, the dumber she got. It was easier for the territorial nature of her hippo side to take over this way, easier for to sublimate her mind. Soon her thick hands fell into the muck once more like twin cannonballs. Massive splashes of mud covered the underside of her mouth, and the cow hippo paused for a moment to smile.

That felt good… That felt like… No. She couldn’t… She didn’t want to… Another haze, another portal she fell through.

This time, nothing of the hippo’s mind remained. This time, her new form overtook her brain in an instant. Josie’s eyes widened for a horrified second as she felt her humanity return only to be cruelly stolen away.

Then she snarled, slinking forwards on all fours with her backside in the air. Why had she been upset about this? The old her was weak. The old her wasn’t like this new form at all. She looked down to her arms to find orange and black stripes dancing across her flesh like wildfire, burning bright.

“Tiger, tigerrrrrghh…” she growled, though there was no trace of an animal’s baritone in her voice. This time, she wasn’t losing the ability to speak from physical changes to her form. This time, she’d simply forgotten how to talk.

Josie felt strong, felt powerful. As she began to change, her senses vastly heightened. Her lips chuffed to express her happiness, the closest thing a tiger could manage to a purr. With her better vision, she could see a portal out already. She could see a human environment on the other side, a familiar bedroom. Her bedroom.

With her better sense of smell, she could taste the feebleness of the creature that had inhabited that room, even though she so resembled that weak little girl right now. Josie didn’t mind. She knew that would change soon enough.

She didn’t so much as need to think over her next decision. The tigress spun on her heel, wiggling her human butt towards her old life with a condescending growl. The sound started as a human girl’s impression of a tigress, but deepened by the end of the breath.

Inwardly, a girl clawed at the fraying edges of her mind. The tigress paused for a moment, amused. The right side of her lip quirked upward at the old Josie’s attempt to regain control and return her to a life on two legs. She couldn’t understand it, neither of them could. The tigress couldn’t understand what the human would enjoy about being so pathetic. The human couldn’t understand why the tigress would ever surrender her strength, her senses, her passion.

It was passion indeed that soon drove the minds to a union. A heat awakened between her legs, and for once the tigress was glad some human side of her remained. That side knew what to do in this circumstance.

Her fingers trembled as they reached towards herself. There she was, an 18-year-old girl dyed in the strips of a tiger, on the cusp of surrendering her form. Josie knew that she’d be surrendering herself, and that she’d be giving up any chance at returning to humanity. The tigress knew that if she did, she’d experience the best pleasure of her life.

Josie and the tigress were very much alike in that regard, and that was what made it so easy to descend into the abyss. A serpent was too chilling, a bear was too lazy, a crocodile was too predatory, and a hippo was too oafish. But this, this potential to be so much more than she was, was intoxicating.

She did need to fight against the mental incursion, and the tigress didn’t need to overtake her mind. The two selves bled into one another and left something better than both. Her mouth hung open with an animal’s vacant pleasure as she dexterous Lee worked her fingers along herself.

Fur, so much fur bloomed from her pores, fanning out and giving her a deceptively fluffy appearance. She nuzzled into the soft hairs at her shoulder, slender whiskers able to tell each of the thousand strands from one another. Human hair striped and receded into a sloping skull.

Josie loved it. For once, she loved becoming an animal. The girl who’d walked into the zoo would likely have turned tail and run from the beast she’d become—and Josie would be all the better for it. She yowled with delight and carnal bliss, and her heart soared as a growl replied.

She pressed her palm against the forest floor, feeling it swell and lift beneath her. She didn’t need it anymore, didn’t need those fingers. A dawning realization lanced into her thoughts: she didn’t need to pleasure herself. She had him for that.

A male slowly slinked from the foliage, his fur matted with the sweat and dirt of a life in the forest. It gave him a rugged aspect, the same kind of masculinity that Josie would have killed to have as a human. She turned towards him, arching her back in a feline fashion, flexing her shoulders as they popped.

She wanted this. She needed this. She was a tigress, and every tigress needed a mate. Finally, she understood why the tigress burned so brightly. It was to because she needed to shine to attract such a specimen; to be so richly pleasured and feel a content unknown by any human.

He clambered atop her with grace that defied his strong appearance, and Josie rumbled her approval. She looked back towards him and drank deeply of his scent, tasting the promise of something beyond what words could describe. That was good, because the tigress didn’t need words anymore. She needed action.

She drove back towards him at the same time he drove into her, and the result nearly drove her wild. The rest of her muzzle shot outwards, her body gaining the remainder of its bulk almost instantaneously. She yowled, rewarding him for his efforts and tearing what was left of her human minds into shreds.

Her dreams of a future, memories of the past, and even her present name were all shorn from her mind as surely as though she’d swiped at them with her clawed paws. It left her fully able to embrace pleasure without restraint or concern.

Her massive heart thundered in her chest, and she opened her snout to pant with a ragged, burning passion. She managed three breaths before her feline folds clenched, and she reached the first climax of her new life.

But the male didn’t stop. He hadn’t reached his own peak yet, and so he drove her further and further form her own. His paws clamped around hers, his teeth nipped at the back of her neck. The tigress’s eyes watered with desire and submissiveness, and she angled her head back to nuzzle at him with her ears.

Time became unfathomable. They could have been pleasuring one another for hours, minutes, or even weeks. Trapped in a world of ever-increasing ecstasy, the tigress drowned in delight. She rolled her hips, wiggled her rump, clenched every muscle in her body to coax her mate’s warmth from him.

At last, she succeeded. Sweat covered the underside of her rough paws, and her mouth felt dry from yowling and panting. But she finally felt him tense behind her. Desperately, feverishly, she threw herself back onto him, just in time.

He erupted within her, and a warmth unlike any other filled her, truly filled her. She knew at once that she’d bear him a healthy litter, and chuffed with delight. Then she pulled off of him, almost coquettishly batting at his face with a paw.

The message was clear: if he wanted any post-coital rest with her, he’d need to earn it. Her tail flicked with amusement as she darted from him, hearing the crash of his larger form through the brush behind her.
