Karyn smiled as she examined the dress, imagining dressing her doll. "C'mon, Jon-girl," she called playfully through the door. "This should be easy for you. Tell you what, I'll give you three guesses. If you guess correctly, I'll change you back to normal. But each time you fail, you'll have to do something like a dare. Sound good? Great!" Of course, she hadn't changed him at all since she entered the bathroom. Jon was perfect just the way she was. That didn't make it any less fun to torture her like this. Besides, she wasn't sure if that would work, and she wanted Jon to think she had power over her.
"Is it..." Jon said hesitantly, "My breasts?"
"What about your breasts, honey?" she asked innocently.
"Are they... larger?" Jon asked, her voice adorably nervous.
"Sorry, Jon," she laughed. "That's one. For your 'dare', you can... tell me how much you love them." This would be the test to see what kind of power she really had over Jon. She needn't have worried.
"...They're wonderful, Karyn," Jon forced excitement. "T-thank you so much for giving them to me! I- I love them?"
Karyn giggled. It was so much fun to hear her squirm like this. "Okay, Jon, glad to know how much you appreciate them. I'm sure you can now tell me what's changed?"
"You made them smaller?" Jon asked fairly confidently.
"Nope," she grinned, imagining what Jon's face must look like. "Now, tell me how much you hate having your penis attached."
"Oh, I, uh," Jon stumbled. "It's, um, horrible. I, uh, hate it. I hope I never have to wear it again."
"That can be arranged," Karyn said sweetly. "Last chance, Jon. What did I change?"
