Bree remained in the kitchen, and found her body to be changing as well. But unlike Lena who was becoming more horselike, Bree was reverting to a more human form. More human, not entirely human. The effect of the horseshoe was wearing off, but only for Bree. Lena held it the longest, and her desires were much more corrupt than Bree's. Bast's magic had a much stronger effect on her than Bree.
So as Bree munched on her breakfast, her transformation back into a more human form continued. The fur on her body retreated and then centered around her genitals. Her tail was sucked back into her body, and her legs slowly returned to a human form. But they were much more muscular than Bree's legs had been before the transformation. In addition to her new and improved legs, Bree's breasts had returned much larger. They had been D cup before, and now bordered on G.
The only things to remain fully equine were Bree's genitals and asshole. Which she was fine with. It was easy enough to hide them inside large pants, or a very loose skirt.
When Bast entered the kitchen she found Bree completely naked, without fur covering her body. She smiled when she saw Bree hadn't completely reverted. Bast had other plans in store for her new play things.
