Keep watching

"Yes." You think you are calling her bluff. "I'm going to watch you have your diaper changed." Surely she'll admit that this is all a prank rather than have your mother change her diaper in front of you.

Jane covers her face with her hands as your mother pulls her heavy diaper open, revealing her pussy. She mother gets to work cleaning Jane's most intimate places.

You can't believe what you are seeing. There's no way Jane would go this far for a joke.

Finally, your mother slides a clean diaper under Jane's bottom and tapes her into it. She helps Jane down from the changing table and declares "Let's go have breakfast." She leads the way out of the room.

"You weren't joking" You say to Jane, who looks like she's ready to cry. "This is all real."

She nods.

"How do we change back?" You ask.

"I don't know." She manages to speak. "Maybe the rattle can undo the spell."

"Where is it?" You ask as you hear your mother washing her hands.

"I don't know" She says. "I was in my room when I used it and then I woke up in the cot."

"It might still be in your room." You reason.

You and Jane go to her room and open the door. All of her stuff is gone. Instead, the room is set up as a study with your mother's books and computer which were previously in a study she shared with your father.

"What are you two doing?" Your mother asks, emerging from the bathroom. "You know you're not allowed to play in my study."
