Michelle retired alone to her yurt. Her boyfriend had broken up with her the day before she left, and she was alone in the wooden bunk bed when she noticed a change in her arm. It felt rough, like her legs a few days after shaving. As she mused, she realized that it was fur growing! It was orange, with a tabby pattern.
"Agh! What the hell is that?!"
The fur spread up and down her arm, as her fingers and palm grew pads and claws. When it reached her chest, it exploded outward, covering her other arm and her chest. Her breasts grew to D cups, but somehow felt weightless as the fur covered them. Two more pairs grew beneath them, followed by hair growing around her pussy and a tail flipping up from it, covered in the same tabby streaks. Her pussy and ass changed to be more feline, so she would have to be mounted from behind for the most comfortable sex. As the fur reached her toes, her feet changed so she walked on the balls of her feet. Pads grew, and more claws. Then, the fur moved up her neck to her face, which rearranged, giving her feline eyes, golden yellow hair, cat ears, a cat nose, a split mouth like a cat and cute little fangs. Then, desire hit her like a truck. She needed to satisfy her lust, and fast. She began to encroach on a nearby camper... A girl, alone as well.
Alex was shocked when her door flew open and a sexy cat girl walked in, crouching and slinking around the small wooden yurt.
She screamed. "Get away!" But the cat girl moved closer, and pounced, her body launching onto Alex's, tearing away her clothes until they were both naked. Then, she bent over and sucked and licked at Alex's clit and pussy while fingering her own. When they both came, Alex changed as well. Her change took a lot less time, as she simply rippled and crashed in on herself, her body turning soft and blue as she became a goo girl. She bent inward and kissed the cat girl deeply, flowing slowly into her feline pussy. The cat girl moaned into the kiss as she was filled. They made love until dawn, where they parted ways and the virus developed. On contact with a woman, it would cause change, and it would stay this way until these odd girls were millions strong.
