Stupid laugh or not, Jon was tired of his sisters shit. Jon glared at her. "I'm so done with your bullshit Zoe."
"You're done with this? Well it's no pick nick for me either, but here we are and what can we do about it."
"You're wrong there sis, there's plenty I can do about it." Jon's grinned, he was going to enjoy this.
"Have you hit your head recently? If you try anything funny I'll tell mom and dad. Stupid two feet boy." Zoe sighed as she was still peeing, "Ugh, this takes so long."
"You know what, I don't think you'll appreciate this if I don't change a few details."
"You're talking shit bro and not the good kind. Now get out and I'll call you when I'm done."
"I wish Zoe was aware of the changes I've made and my wishing power."
Zoe slammed a foot onto the tiling. "Didn't you heaa...." her voice trailed and her eyes went wide as the wish took hold. "Oh..my god....Jon..I" she stammered.
"Yes I. Now then, about what I was saying. I'm done with you sis. I wish you were done peeing."
Zoe's stream instantly stopped. "J..Jon, how did you? What are you going to do?" She turned to look him in the crotch.
"I don't want nor do I need a sister. I'd like a pet instead."
"Don't you dare Jon! I'll tell mom and dad!" Zoe shouted defensively, her voice was shaky.
"I wish you were roughly the size of a large hamster."
Before his eyes Zoe shrank smaller, her clothes quickly started to get loose around her. She kept shrinking until she disappeared into the shirt she'd been wearing.
Jon just stood there, watching a small bump find her way out of the crumpled up clothes.
Zoe slowly crawled out. "Jon! I'll tell!" Her voice was barely audible and Jon laughed as the tiny naked Zoe tried to hurry to run to the doorway.
"I wish Zoe was in a hamster cage."
A large cage appeared around her, she skidded to a halt right before she hit the side.
Jon crouched next to the cage and peered through the bars. The cage was fully furnished, with a small hamster house in the corner, a hamster wheel to the side, a drinking bottle and a small bowl to eat from. Zoe was standing on the soft bedding, her swollen pussy and front ass turned towards Jon. Her eyes were furious.
"Jon!" she squeeked angrily, "Undo this....please?" she ended meekly.
