Jeff had found the option for a cow transformation. Something about that option quickly gripped him as he pressed it, bringing up a list of options. Gender settings, amount of transformation, and time, even an option to shift reality so no one would notice anything. Thinking about how He had wondered how cows worked at one point Jeff started editing the options.
Partial transformation
Species: Cow
Gender: Female
Time: 1 year
Reality shift: Yes.
Satisfied with his options Jeff clicked the start button before sitting back in his chair. He sat for a moment before he felt himself fall out of the chair and land on solid dirt and grass.
Jeff quickly got up from his encounter with the dirt before looking down, blushing red as he quickly noticed his lack of clothing now. Looking around he saw he was in a field with a barn off to the side, there were some bulls and cows around the pasture as well.
Jeff started walking over to the barn as he started to feel a tingle in his nether regions. Looking down he gasped as he saw his penis shrinking. Amazed he stopped walking for a moment as he watched as his penis shrunk to a miniscule size before entering a silt that had formed in place of his penis and balls.
Jeff blushed as she realized what this meant, deciding to hurry over to the barn Jeff ran inside, thankful that it was empty. Sighing Jeff looked down as her new vagina, touching it with her hand she shivered in pleasure before pulling away.
Waiting for a bit it wasn't long before the tingle started again, focusing on her belly. Jeff looked down and smiled as four small bumps started to form on her stomach, her belly button shrinking away to nothing along with her upper nipples. The skin around the bumps turned pink as they slowly pushed out, small holes forming on each of them. Feeling the pink skin Jeff felt it had a rubbery texture as it started to expand, forming a rather large udder, and forcing Jeff to place her legs apart to be comfortable. Once the udder finished forming Jeff noticed that it had overtaken where her vagina was, feeling around her ass she found her vagina again just below it, moaning as she touched it.
Deciding to play with her new udder Jeff pulled on one of the teats, moaning as she felt the pull of pleasure from it. But then the tingle started again and Jeff started to feel hungry. Waddling over to the barn door Jeff pushed it open before falling to her knees and starting to shove grass into her mouth. As she ate she feel a welt form a over her ass and her new tail pushed out, swinging around as she ate. Her ears tingled and extended, flicking at the sounds of her eating and the other cows eating. After spending a few minutes eating Jeff got up off her knees, turning around to see her tail swinging and feeling her flicking ears.
Suddenly Jeff's stomach gurgled, placing her hands a over her udder she felt a large amount of waste moving to her ass. Feeling an extreme need to do her business Jeff suddenly felt a large mushy turd push out of her ass and splint on the ground, around her feet and legs. Blushing red at that she felt a long stream of urine spray into the cow pat, splashing on her legs as well, but she didn't care about that.
Waddling back into the barn Jeff heard the gathering of flies around her ass, tail swinging instinctively to get rid of them before closing the barn door. Feeling sloshy Jeff sat down on a bench in the barn, rubbing her udder. She felt as a liquid started to fill it, expanding the sac so that she had to spread her legs even further. Moaning from the pleasure of her udder begin filled she placed a hand on one of her teats and pulled, milk shooting out of it onto the ground of the barn.
While Jeff emptied her udder the tingle started again, focusing on her feet, turning them black and balling them up into hard hooves, her legs snapped as well, making it so that she would now walk on all fours. Feeling the tingle move up her lower region Jeff moaned as black and white fur covered her lower area up to just a over her udder. Finally emptying her udder Jeff tried to stand up, but fell onto all fours.
Saddened Jeff looked at her body as it started to tingle again, this time in her legs and midsection. They started to bulk up, not to the large proportions of a cow, but a fat curvy proportion as fur started to expand up to her neck, going down her arms.
"Well it did set it to random amount of change." Jeff said, surprised at her human speech. Looking down at her hands she watched sadly as they blackened and hardened into two hooves and her arms locked into position. Now she could support her weight.
Now her face started to tingle. Looking at a piece of broken glass over in the barn she watched as her male face shifted into a feminine one, abet a girl with cow heads and a cow's body behind her. Jeff smiled as her changes all finished.
