Stacy's skin began to change immediately. He skin tingled, felt like it was crawling across her body, although it wasn't of course - that was just her genetic makeup altering to accomodate her step into poultrydom. She moaned in discomfort as the physical changes began.
Her legs were the first to alter, skin drying, flaking out, becoming much less pleasant to the eyes than they were typically. Tanned, toned legs were becoming dry and scaly, losing colour, her toes lengthening into ugly, bony talons. Above the knees, however, the human muscle was keeping its form nicely, although what was underneath was scientifically more like the "drumsticks" Tom had muttered. Her skin was thickening, becoming prickled... she recognized the texture. "A chicken," she thought to herself in a panic. Her eyes flashed at Tom. He was turning her into a chicken!
Feathers now all about her body, her hands were a lot like her feet, now, although the talons were much longer, and covered in more thick white feathers. The binding over her mouth was torn loose as a yellow beak formed, and her hair began to shed in clumps. Her slim hips were now thick and fat, an egg-bearing hen indeed.
The transformation was almost over, and Tom was satisfied. "Now, just what to do with you?"
