After another 2 hours of driving, she finally arrived at the farm where she will spend her actual vacation. Since now, there was nobody who knew the pretty mare was really a guy, who wanted to escape his life for a while. As a mare, he, now she, could release herself, go wild, not worry about anything, just... be a horse.
April quickly learned that her caretaker was a girl, named Elise, short, petite, dark hairs, b-cups... she would definitely get hard if she was a stallion. Being mare had its advantages after all.
April had to get used to being ridden every day. But they cared about her really well. One day she was used even to promote the farm, as a model horse. It wasn't too pleasant, if anyone would know, they would make fun of her. But nobody knew. She could free herself, her new needs, play dumb.
After all, it wasn't a bad life, maybe a bit boring, but she didn't have to worry about going to work, paying bills, talking with other people. After some time she found that her body "works alone", like on autopilot, so she could just enjoy being. Also when she had trouble with doing some tasks and tried to oppose, her body reacted on its own, against her mind. She took it for an assisting system that helps her act as a proper horse, so nobody would suspect her being a changed human. It also made her feel right about what she's done against her will.
After a week, she had used to this life, like she was really this horse... 3 more to go, then back to her former human male self.
