Alana could feel the animals near by, they were all connected, one big family. One big Pride.
She ran naked under the sun, feeling completely free and uninhibited. As she ran she could feel her changes continuing. Her shoulders popped as they widened, her rib cage was expanding and her waist thickening. Everything was growing, and taking on a stronger, more masculine build. Her legs stretched as she ran, lengthening her stride.
A tingle ran down her spine. Without stopping to look, she knew this was a line of fur quickly extending down from her bestial head and neck. As this reached her tailbone, that vestigial footnote of human evolution surged with new purpose. Flesh and bone pushed outward, quickly gaining animation, swaying back and forth to balance her strides. The tingle continued down to the tip of her new tail. Had she paused to check it she would have found it to be nearly four feet long and six inches thick including the girth added by the plushness of her pelt.
She reached the lion habitat, unerringly seeking the second lioness she had watched on the monitor.
Alana knew the animal as Nala, uncreatively named after the children's cartoon character. As she approached, the massive herm lion was sitting sphynx-like under a tree. Shi was motionless, if not for a faint breeze rippling hir mane, the cat could have been carved from onyx.
Alana knew what she wanted, she turned away and went down on her hands and knees, new tail raised high...

Danielle waited outside the building, looking for a white transit van. Shi had been able to fill Jay in on what was going on, leaving out hir creation of the new virus. Shi instead spun a story of Dalton and Clyde being the source of hir and Alana's infections.
Danni could feel hirself slowly changing further as shi waited. Hir chest was pushing outwards as hir ribcage deepened and expanded, thickening pecs adding further bulk. Hir torso had completely lost any semblance of a womanly hourglass, and was now a broad shouldered 'V'.
Danielle's cock and balls continued to grow with the rest of hir, the hardness of hir permanent erection rubbing pleasurably with every movement of the lab coat. Shi was also becoming extremely uncomfortable wearing it, and knew that within the hour shi would take it off, never to wear clothing again.
To hir relief, Jay's white van came bouncing into view, taking the gravel road much too fast.
