Eileen began to feel a tugging sensation in her chest. Her shirt was feeling tight, way too tight. Eileen looked down and saw her breasts growing, and multiplying. Eventually they became too large for the confines of her shirt and they undid her buttons. Eileen's bra was growing tighter by the second thanks to her enlarging boobs and broadening back. Her growing second pair of teats clearly showed what Jimmy was turning her into: a cow.
Eileen was terrified. She didn't know what she had done to deserve such a fate.
"Why are yoOOou doOOOoing this to me?" Eileen bellowed in despair.
"Well, we couldn't let you go, and besides, you certainly already had the perfect chest for being a cow. Your boobs were practically udders already!" laughed Jimmy.
"YoOOou're turning me into a coOOow because I have big boOOOobs?" Eileen said incredulously.
"Don't be that offended, he turned me into a pig because I have a fat ass!" joked Petula.
Eileen didn't take much solace in Petula's words, the strain her udder was putting on her bra grew too great. It eventually snapped clean off her body, exposing her new milk-bearing teats to the world (or at least to Jimmy and Petula).
Eileen doubled over. Her arms and legs were growing and fattening to support her increasing weight. She saw her fingernails expand and blacken, eventually covering the whole of her hands. Within a short time, she saw that she had fully functioning hooves. Eileen couldn't look back to see it, but she imagined that her feet were undergoing the same metamorphosis.
"Please! Make it stoOOOOop!" Eileen pleaded as her face began to change.
Her nose expanded greatly. She could smell all sorts of new scents, most particularly all of the appetizing greenery in the area. In the distance, she found one particularly exciting scent. Eileen didn't know it yet, but that scent belonged to a virile bull that would happily accept Eileen as a mating partner.
Eileen's lips became bloated and her tongue fattened within her mouth. She felt around inside her mouth to find that her teeth had changed to fit her now exclusively vegetarian diet. Eileen grimaced and closed her eyes as her pretty face began to push out into a bovine snout. Even her ears grew larger.
As Eileen's udder moved down her body into its new resting place, her legs and ass exploded with fat, shredding her shorts and panties. Her ass now contained not only her anus, but her vagina as well. Eileen began to subconsciously swish her new tail about, anticipating the insects that might be attracted to her new stinky butt.
As the rest of her body began to fill out with fat, Eileen started to rapidly grow some light brown fur. Within a few moments Eileen was completely a cow, who, like Jimmy's other victims, had retained her original, long, brown hair.
A giddy Petula looked over to Jimmy. "Well, that was fun! What are we going to do with her now?"
