"Well, love, you've got a VERY eager test subject right here," Tabitha told Rick with a smile.
It was true. While Tabitha had initially thought of Rick's attempts at the lycanthropy formula as silly, she'd gradually warmed to the idea. Now it had gotten to the point where she seemed genuinely curious about trying it.
Rick strapped on his gas mask again as he prepared the lab for her. Opening the container, he turned on the exhaust fan to prevent the fumes from spreading too far.
The effect on Tabitha was immediate, and impressive. Though she was attractive when he married her, motherhood and age had softened the looks she had in her youth somewhat. However, just as the gas had invigorated Rick, it began to work upon her, smoothing laugh lines, tightening her build, and rejuvenating her skin and hair. Within moments she had been restored to how she looked in her early twenties.
She continued to change, both in appearance and bearing, the overall effect lending a sense of feral mischief to her look. She smirked impishly, twirling a lock of her rich chestnut brown hair around a finger.
"This feels amazing, Rick."
"Pity it's not permanent. I'll figure out a way though, honey."
"I'm sure you will. Then we can both be night howlers."
She winked and smirked again toothily, the first hints of sharpening canines showing. Her green eyes were already showing flecks of gold as they slowly faded to that vivid shade. Tabitha let out a happy sigh as her ears began to stretch and twitch, growing to points which poked from the thickening and lengthening mass that was her increasingly wild and manelike hair.
She stroked her arms, rolling up the sleeves of her sweater as a downy brown growth sprouted, her nails pushing outwards, darkening into claws.
Soon, the confinement was too great for Tabitha, and she hooked her fingers under the bottom of the sweater and pulled it over her head. Fumbling with the fly to her jeans, she eased them down her legs, revealing the dark hairs spilling from the crotch of her panties.
The change quickened, hackles creeping out from her shoulders and back as a ruff blossomed on her chest above her breasts. Tufts of fur splayed out from her cheeks as she licked fangs that had finished growing at an inch apiece. With a wicked grin, she reached down and tore her panties off, the sound of tearing fabric echoing in the room as a wolfish tail budded from her tailbone and grew to a luxurious length of three feet.
Her nose darkened and turned upwards as her mouth and brow began to jut from her face. Moans became snarls as a small muzzle developed, finishing her change.
Rick grinned at his wife, but realized he'd have to cut her off now, before she got any ideas. Capping the liquid, the exhaust fan swept the remaining vapors out of the room.
Slowly, Tabitha's form reverted, the lycanthropy retreating back into her.
Oddly enough, her restoration was not complete.
Tabitha had retained her youth, as well as the feral bearing Rick had noticed, and something else besides. Her eyes remained an eerie yellow-green, and her ears still bore vague points. Her canines were still visibly sharp, though they could pass for human. Her hair was still manelike, and her body hair was untamed, as if she had never shaved a day in her life.
She looked herself over, then looked back to Rick, a little unsure.
"You know what this means, don't you dear? It means I'm infected..."
