Selena, naked as a jaybird, eagerly watched the moonrise from her window as she eagerly prepared for her first shift. It wouldn't be much, she knew, but it would be more than she'd ever managed before. She stared intently at the full moon, meditating on the Goddess and silently willing her Change to begin.
Suddenly, Selena felt a strange tingle within herself. As the moonlight spilled upon her, she saw little hairs begin to poke out of her skin. As the hair sprouted, Selena suddenly felt overwhelmingly aroused. Unable to stand it, she began toying with her pussy lips as the hairs grew in. To her amazement, she could actually feel her once sparse pubes blossoming into a dense, '70s-style jungle of a bush under her palms. As she stroked herself, Selena felt her nails sharpening. She shuddered at the delicious sensation of her pointed nails dragging over her pussy, pricking and tickling it.
Trying not to accidentally draw blood, Selena positioned her proto-claws over her clit and began to tease it. The pricking sensation was almost painful, but so intensely erotic at the same time. She felt her orgasm beginning to stir within her crotch. She rubbed feverishly at her rock-hard nub, panting like the savage wolfgirl she dreamed of becoming. She howled and curled her clawed toes as the climax surged through her, making all of her new hair stand on end. She gripped at her treasure trail ("Sweet Jesus, I have a treasure trail!") as she rode out the nearly unbearable waves of stinging pleasure.
Once her orgasm wore off, Selena made a beeline for the floor-length mirror. She was greeted by a much more feral reflection than she remembered. Every inch of her body from her neck to the tops of her feet were covered in hair. It wasn't so thick as to resemble fur, but it was more than enough to make her look like she was suffering from clinical hirsutism. From her feet to her legs to her pussy to her ass to her back to her belly to her tits to her chest pits to her arms and even her shoulders, everything had a generous dusting of curly red hair.
"Hmmm..." Selena mused as she studied the long red hairs. "I wonder when it'll turn silver like Di's fur. And when it'll spread to my face." She stroked her regrettably hairless cheeks wistfully. "Oh well, slow burn."
Of course, Selena's hairiness wasn't her only change. Her fingernails and toenails had elongated and sharpened, well on their way to becoming true claws. Her nose had also flattened, giving her face an animalistic cast. The redheaded wolfgirl smiled, revealing her lengthened, fang-like canine teeth.
"Wow!" Selena said, hugging herself. "I may not be a full werewolf just yet, but this is already the hottest I've ever looked!"
