Michelle moaned, "Oh god yes!" She hadn't realized the sun setting or the chill that ran down her spine as the cool night air set in. The incubation period had concluded, and the virus began to work at her easily altering human DNA. A warmth filled her insides, the stomach and bodily systems reacting first to the virus, but it did nothing but increase her libido, as she fingered herself and groped and squeezed at her tender breasts. An odd feeling pressed at her abdomen, the growth of new nipples and budding breasts below her own, without realizing their addition, she continued her self-pleasuring. As virus worked its way into her skin, she began to tingle all over, increasing her stimulation. "Oh.. ohhh!" Michelle cried out, her fingertips and digits expanding and developing calloused prints and nails developing into wicked claws. The fur thickened fastest around her moist sex, collecting her musk and accenting the forest with the scent of a panthress. Her toes dug into the dirt, also broadening and becoming paw-like, the big toes on each foot curving out and upward into a dew claw. As the black fur swept over her white skin, thickening over her new paws and breasts, a cracking sound eminated from around her tailbone. "Unngh!" Michelle growled, collapsing over, the pleasure mixed with an odd painful sensation. Her bottom raised, the furred nub pushed and cracked, as new bone and tissue extended outward. She found that the new appendage could be swayed, it grew outward and enticed an enjoyable purr. Soon the virus was altering her furred human face, she winced as her teeth sharpened and a painful stretching of her mouth and nose began to develop. She growled, nose uplifted and fangs as her lower face pushed and swollen into a feline muzzle, the pressure hurt but also was enjoyable. Human ears pointed upward, and though didn't fit over her head, were a mix of elfish and feline appearance. Her blonde locks had fallen loose, scattering onto her shoulders or the loose dirt as the panthress recovered from her changing face. Michelle gasped with the moonlight behind her, yellow eyes opened and changed to see better in the night. Her appitite wasn't settled yet, and Michelle set out to find her first companion, leaving behind her humanity.
