Sadie and Greg pulled on their shoes and ran down to the cow fields. Since their father had disappeared a year ago, their mother had taken over the running of the farm, and the twins had volunteered to milk the cows. Sadie was the older of the two, thirteen years old with the beginnings of small breasts growing on her chest. She had been in therapy for the physical abuse her father had visited upon the two of them, as out here no-one could hear them screaming.
Her mother stepped in when she could, but she had been as scared of them as the twins had been. Sadie sighed in relief that she wouldn't have to worry about that anymore. Greg ran ahead to open the gate for the two of them. He hadn't been spared from the abuse she had experienced, but she always tried to take the blame for anything that would have gotten him beaten so she could endure it instead of him. Older siblings were supposed to protect younger, afterall. Greg was only ten, and Sadie smiled at the fact he didn't seem to have lost the exuberance of childhood. She had had to grow up too quickly, in some ways.
"Sadie, are you coming?" Greg called, pulling her out of her thoughts.
"Sorry, yes," She jogged forwards through the gate as Greg pulled it shut behind her.
The two were accompanied by their sheepdog, Flint, who could also help to round up the cows, but they were usually well trained to come for milking if they rang the bells.
Sadie rang the bells, and the cows began to follow them towards the milking shed at the edge of the field.
The family farm had five cows: two males and three females, though Sadie had noticed one of the female cows was pregnant the last time she'd been in the fields. As a general rule, they didn't milk cows that were close to term in-case it was required for the calfs, so only two of the cows were being milked that morning. While they were milking the two cows that were not pregnant, Sadie noticed Staci, the third female cow, currently pregnant, acting strangely.
She was moving erratically, faster than any of the cows usually moved. Concerned, Sadie left Greg to milk the cows and approached warily. A panicking cow might kick out blindly, and Sadie did not want to get kicked.
"Staci, you alright, girl?" Sadie asked, her voice gentle. Staci ignored her, and... was it Sadie's imagination, or was the cow smaller than it had been a moment before?
Another moment or two of watching, and Sadie was certain the cow was shrinking. Sadie stood stock still, her surprise at what was happening before her eyes making her forget even the danger of the cow's hooves... which didn't look like hooves anymore. Strange, long thin growths were growing out of the front hooves that it took Sadie a few moments to realize were fingers and a thumb, as the back hooves elongated, forming feet. The cow mooed in discomfort as she lay down, rolling onto her side as her weight was unable to be supported by the strange new appendages. Fur retracted into her as her skin became lighter, almost the exact same as Sadie's own skin.
Greg had noticed what was going on at this point, and was caling to Sadie to get away from it, but Sadie didn't hear him, transfixed by what was occurring before her eyes.
The fur retracted all over her body as she shrank, her udders moving up and merging, becoming a single pair of breasts like beachballs, and her belly remained swollen, suggesting the human, for that was what the cow was becoming, Sadie realised, was still pregnant.
As the transformation concluded, the woman panted, barely able to keep her eyes open, let alone stand. She fell asleep in the grass.
Sadie exchanged a look with Greg, and the two...
