The warm evening filled the bedroom with a soft amber glow. Jessica stood near the edge of the bed in nothing but a flannel shirt. The fabric clung gently to her curves, the top buttons undone to reveal the full swell of her breasts. Her long dark hair cascaded over bare shoulders, and her nipples stiffened against the cool air. She was naked from the waist down, her bare feet sinking into the plush carpet.
Her fingers wandered to the necklace at her throat. Black, smooth like obsidian, suspended on a thin leather cord. A charm in the shape of a paw hung at its center. It pulsed. Just faintly. Like a heartbeat.
Then she felt it.
Heat. Deep, swelling heat between her thighs. Slow and thick, as if something inside her stirred in response. Her hips shifted, grinding subtly as her thighs rubbed together. She bit her lip, pressing her palm to her mound. She was wet. Soaked.
A moan escaped her lips.
Then the wave hit. Pleasure bloomed like fire under her skin. Her thoughts started to slip, becoming soft, foggy. Her skin tingled, stretched, warmed. Beneath her fingers, her flesh felt different. Softer. Hotter. A fine, short fur was growing where there had been only smooth skin.
Jessica gasped. Her arms trembled. A rush of heat surged through her chest. Her nipples throbbed, almost painfully sensitive, and when she brushed them, she moaned again. Louder. Not human.
Something in her voice changed. Thicker. Breathier. Almost a whimper.
"What... what's happening to me..." she whispered, but the sound was more a pant. Her breath was shallow, fast. Her body wanted more. Her knees gave out, and she fell forward onto all fours, her back arching, hips rolling.
Her nose twitched. Then grew. Cool and moist, black like polished leather. Her ears tingled, pulling higher on her head, lengthening into perky, furry points. When a distant bark echoed from outside, her new ears perked up instinctively.
It was a signal. A trigger.
A pulse of raw, feral lust exploded through her.
She groaned as her shirt slipped off her shoulders, revealing the full, naked curve of her back, now dusted in fine chocolate-brown fur. Her breasts swung free, heavy, sensitive, brushing the soft carpet below as her hips rocked involuntarily.
Her pussy throbbed. Hot, swollen, slick. She spread her knees wider, instinctively presenting herself. But she didn’t want fingers anymore. She wanted something bigger. Something male. Something animal.
A thick shiver raced down her spine as pressure built at the base of her spine. Then it burst. A tail sprouted, flexible, lively, wagging nervously on its own. The pleasure was unbearable. Her back arched. Her body trembled.
"I'm a bitch..." she moaned, one hand caressing the side of her new muzzle, the other slipping down over her belly, stopping just before her dripping folds.
Everything was heightened. Every breath, every scent, every inch of skin felt electric. Her own smell was intoxicating. Warm. Female. But already touched by the scent of a bitch in heat.
She panted on all fours, tongue lolling slightly. Her eyes rolled back. Her body was no longer human. It was soft, obedient, hungry.
She was no longer Jessica.
She was a bitch. And it felt so good.
If only someone came now. Caught her like this. Smelled her. Claimed her. Taught her what it meant to be a good girl...
