Mary heard her dog, Patti, whining outside the door, wanting to be let in. That gave her an idea on what to try first. She limited the changes to herself and Patti.
Patti would still be a dog, and she would still be a human...but their roles would reverse, and changes necessary to support that. She saved the program, and finally, after a few moments of deliberation, she hit run and a sixty second countdown started on the screen...with the heading...preparing changes.
Mary opened the door, letting Patti into the room. Patti barked excitedly to see her, and Mary saw the innocent happiness in her eyes...something she envied. But, it wouldn't be much longer now before it was hers...She patted Patti on the head affectionately.
The countdown hit 0, and a new message, "Executing changes. Please stand by."
Mary's fingers began to fuse together, with thick dark pads appearing on her palms. She only had a few seconds to marvel at them before her legs began to ache, and she fell down on all fours. She could feel her body shifting inside her clothes, and she looked up as her head swiveled around her shoulders.
She saw Patti leaning on the side of the chair, pulling herself up with one of her two forepaws...which looked much more like hands...as she stood, her hind legs fell flat on the floor, and she stood up straight. It felt like she towered over Mary.
"Wow," Mary exclaimed, amazed. "You look..." She tried to complete her sentence, but she suddenly couldn't...her throat just couldn't make those noises anymore. Her pet was standing like a person over her.
It was then she felt a tingle in her mind. And suddenly, the dog in front of her seemed...gigantic. She hadn't grown...it was a feeling of...submissiveness for her master.
"What the...hell," her master said. "Mary, how'd you get into those clothes? You're going to rip them..." The dog began to help her out of them, leaving Mary completely naked, something she didn't mind...it seemed to be normal. As she finished, Mary jumped up and licked her face, causing the dog to giggle. "Honestly, it's so hard to get mad at you..." the dog said, scratching behind her ears
Mary whined in pleasure, grinning from ear to ear.
