Cally decided that she wanted to try another of the vials effects. Deciding that she'd better return to
normal first, she waited for the vial to turn white before she drank. Immediately she felt a falling sensation
as the floor rushed up toward her. Accompanying this was a tightening sensation all over her body as she
dwindled and shrank back to her normal size. Once she'd stopped shrinking, Cally watched the vial change
colors, deciding which one to try next. Deciding she wanted to try something bizarre, Cally almost tried the
black and white potion before deciding that a random change was just little to risky. The black dots on the
white background had given her another idea however. Waiting until the vial turned green, Cally drank and then
said "Cow" as the book instructed.
Cally felt her stomach rumble, and for a second she wondered if she might get sick. Then with a gurgling
sound her stomach began pushing outward, becoming pink and feeling like it was full of fluid. With audible
pops, four small teats appeared, growing longer as her stomach swelled into what Cally realized was an udder.
Her ears began to feel like someone was pulling on them as they moved to the top of her head, elongating and
growing fur which began to spread down her face. Two small horns erupted from her forehead, and Cally felt her
spine elongate into a tail which began swishing behind her rear. She felt a crack as her hips began widening
and her ass expanded outward. Cally watched as her feet elongated, her toes fusing into hooves. Black and
white fur began spreading up her legs, which rapidly started gaining mass. More fur spread to across her
swelling backside as her lower half became more and more bovine.
Cally felt her breasts fill with fluid, and begin to swell before her eyes into a pair of enormous udder-
like mammaries. She felt the weight of her new assets painfully pulling her down as her nipples lengthened
into small teats. Relief came as her back muscles enlarged as her torso swelled outward, fur beginning to
appear. Looking in the mirror, Cally saw that while her mass was increasing, her height remained the same,
giving her a much more voluptuous appearance than she'd had before.
She began to get a strange feeling from her breasts, and looked down in time to see two new breasts erupt from her chest and swell outward until they were they same size as her original pair. Fur began to spread down her arms as two of her fingers merged with the other two, hoof-like nails forming at their tips. Her face pushed out into a muzzle as the fur spread to the last of her body. As she swelled larger and larger, Cally began to feel a pressure building within her, as if she was about to explode. Seconds later, her prediction came true. Cally heard a series of cracking noises as her bones stretched as she grew in height and mass, going from 5"4" to over 7' in a matter of seconds. With that last sudden growth spurt, the transformation ceased, leaving Cally fully changed into a voluptuous anthro-cowgirl.
