Mary noticed these the wet spots getting bigger on her shirt. She took her shirt and bra off too. Milk has spraying out of her breasts and getting everywhere.
She tried running around the house to find a bucket or something to contain the milk, but fell down after a few steps. She wasn't used to these new hooves and gave up on running and got back up.
She then noticed that the transformation was still in progress! She was looking at her hands as they slowly formed into hooves. By then she had also grown a mussle. Mary's hands were now hooves by then and were as big as her others.
Mary was still standing, and tryed to walk to the bathroom to contain the milk that was still bursting all over the place. This was also happening with her udder too.
To her surprise she looked like she was still transforming. Her butt, breasts, udder, and herself were growing. She was getting very heavy from all this new weight. She was also getting a little fatter. Soon the growing stopped and her butt, breasts, and udder were now notably gigantic. She was will lactating though.
She now was at the bathroom and found that the door was closed. She tried opening it normally but with her hooves, she couldn't twist the handle. This was kind of embarrassing. She couldn't even open a door with her new body and had to find another mean.
