"Claws! What? How is this possible?" Karen yelled.
Her finger nails were being pushed out by sharp talons growing out of her finger tips. Staring at her hand, mouth agape, Karen felt a painful cramp in her feet, legs and toes. Her shoes tore open revealling that her toes also had sharp claws growing from them. Now her feet looked more like paws. Karen tried to stand and look in the bathroom mirror but as soon as she stood up, her legs cracked and she dropped back to the floor. Karens legs continued to pop and move under her skin as they reformed themselves into a more digitigrade stance. Thats when Karen saw the fur. It was thin at first but filling out rapidly starting with her hands and feet and working it's way towards her torso. The thickening coat of hair moved up her limbs while the muscles beneath grew, bulging and stretching her skin. Karen held up her left arm and noticed the color patern on her new fur was orange with black stripes crossing over it.
"T-t-tiger stripes?" Karen questioned. "What is happening to me?".
The pain had subsided a little at this point and was giving way to a much more pleasurable sensation.

The fur had moved it's way up her pelvis and started to work its way up her belly. Her new fur covering her groin felt strange but electric to the touch. She reached a hand down to tease her clit. Waves of pleasure coursed through her body while she worked her sex.
"OUCH!" She jerked her hand up. "Damn! I forgot about these claws."

"Mmmmmmhmm! AAGH!" Karen arched her back, starting to orgasm.
A tail snaked its way out from her backbone and started growing fur. Fur overcame her shoulders, it started to spread over her torso and up her neck. Two more pairs of breasts had started to grow below her original ones. Using her other hand, Karen reached up to grab her growing breasts. She brushed her arm over her new nipples and sent herself even farther into orgasm. Her new boobs stopped growing when they were just smaller than the pair above them, making her profoundly well-endowed. The last changes were taking place now. Karen felt her face pushing out into a feline muzzle. Whiskers poked out from her upper lip. Karen's once slim nose had turned pink and triangular. Finally, her teeth reformed and sharp fangs replaced her canines. Karen let out a mighty roar and climaxed. Orgasms rolled through her body making her shutter in pleasure.
Karen sat, exhausted, on the floor. New instincts were manifesting themselves in her mind not the least of which was to...
