The story of Katie, a woman who indulges in her monstrous transformation for pleasure

Katie tossed her shirt aside, smiling to herself as she kicked off her shoes, stepping into the moonlight. She unbuttoned her shorts, wiggling out of them while still moving. The moonlight tickled her skin in an exhilarating way making her shiver. She smiled, letting her chestnut skin bask in the light. She had gone too quickly last month, this time she intended to savor her transformation.

She took off her bra, leaving it in the dirt behind her. The moonlight glazed gently across her breasts, making her skin tingle. Katie carefully pinched her nipple, letting out a soft moan as a shiver raced through her spine. Then she doubled over, yelping loudly as pain raced through her body. Her stomach felt like it was twisting in on itself and her lungs felt like they were collapsing. Prematurely, Katie let out a howl, arching her back and neck inward and staring straight into the sky.

Admittedly, her attempt was pitiful, but her transformation hadn’t even begun. She closed her eyes, concentrating. She felt the searing pain in her spine as it began to stretch and winced, a pleased smile across her face. Just above her ass, a small nub began to protrude, pushing at her panties. She concentrated harder, willing the magic of the moon to focus on her tailbone. The nub stretched long, pulling at her panties until they could stretch no more, and tearing through. The stretched and torn fabric slid uselessly down Katie’s legs, stopping at her ankles, she kicked them off into a bush.

She lost her concentration for a moment as she happily swished her tail, which was rapidly sprouting thick black fur. Katie screamed as suddenly she felt as if someone was repeatedly pummeling her in the gut. She squeezed her eyes shut, focusing on her exercises. She let herself feel a little relief when she felt a disembodied tugging on her ears, stretching them to points. She spread her fingers as far as they would go, gritting her teeth as the bones lengthened inside and the skin stretched to match, making hideous pops that made her wince each time.

Fur was beginning to sprout across Katie’s skin now, she ran her hands along her skin, feeling the fur, letting it grow. She stumbled forward and fell as pain shot through her feet, knocking her off balance, she braced herself against a tree. She let out another howl as her feet began to change, stretching and reshaping themselves into hideously beastlike features, her socks were being tested for all their worth, the hems and thread ripping and stretching. Katie groaned a combination of pain and laughter as her feet became misshapen and deformed, the bones reshaping and the muscles stretching. She screamed as her fingernails began to extend, the nails curling into themselves and coming to vicious points. Her toes bulged as her nails began to extend and expand, she screamed even louder, the pain near unbearable, but Katie liked it that way. She dug her claws into the bark of the tree, crying out in pain.

As she did, a passionate moan escaped her lips. She took a breath, then moaned again, distracted from the pain of her feet by a near orgasmic feeling through her body as her wild curly hair gently grew longer, snaking down her back to her tail. Katie turned around, bracing her back against the tree. She let herself become enraptured in her hair growth. As her hand began to creep down her stomach towards her nethers, her concentration lapsed. That was all it took for all the changes Katie had been holding off to come in full ****.

Katie screamed as her insides ignited, she keeled over, falling to the ground. With a series of hideous cracks, her spine arched, pushing against the skin of her back. Katie felt like her back was being beaten with sledgehammers, trying desperately to regain her control, she let out another scream as her spine began to stretch, elongating itself, pushing Katie’s head away from her legs. A series of sickening pops came from Katie’s hips, her hips began to shift in their place, fitting a new shape.

Katie tried to stagger back to her feet, but her legs gave out and began to extend. Katie screamed again, but this time not in pain. “Yess!” She howled, “More!” Her body began to bulge and distort as thick muscle mass painfully took place across her form. Her chest felt like it was being stabbed from the inside out, looking down, she saw her ribs poking against her skin. Her body swelled to match her growing skeleton. “Ohhhh!” She cried out.

Then her face began to rip with pain, her mouth felt like it was being ripped in two. Her teeth ached as if she had been punched in the month, her nose started to push outward, pulling her face as if with a hook. Her mouth extended into a long snout full of vicious teeth.

Katie’s eyes were stung with tears, the changes were coming too fast. She howled a third time as her body was racked with a surge of incredible sensation. Her breasts swelled outward, her nipples hard enough to graze the dirt.

Katie screamed one final time as all her limbs dislocated themselves, replacing themselves at different angles. As her scream turned into a proper canine howl, Katie’s Human mind faded away, replaced by the beast.

As the golden beams of the rising sun cast onto Katie’s dark naked body, she stirred awake. Checking her surroundings, she sighed. “Dammit, went too fast again.”
