The now spirit girl flew through her house looking for something to possess, as she was looking Katy heard her dog Bruce barking at her in an angry way.
"Oh? Bruce!" She flew to him as he tried to chase her. Bruce jumped and tried to attack her but he only went through her without a scratch. "Calm down sweetie, I'm Katy! Just with a... Little change".
Her dog keep barking like she was a total stranger, Katy had no other choice. "So things are like that huh? I hope this will make you notice who I am~". Katy flew to Bruce entering his body, for a couple of seconds he remained frozen but then his black eyes turned into the green pair of Katy, feeling how her soul settled into her new body, getting familiar with her male cuadruped canine form.
"I can't believe it, I'm Bruce now!" She could speak even if Bruce couldn't. Katy unconsciously waved her tail thinking that maybe that were one of Bruce instincts, also could feel her dog's mind inside her but kept him in a quiet state to not bother her for a while.
She decided to have a little walk, the door was open so she exited her house to walk through the streets, she felt her canine dick getting hotter so maybe she could fuck a female dog, change herself into a strong anthropomorphic dog scare people or fusing herself with another animal, maybe a person, her fun was only getting started.
