Karyn realized that their was a possibility Jon wished his stone to her as he trusted her with it, after all with the breasts and hair she learned her lesson.
While Jon had his secret box beneath his bed Karyn has a secret spot too, she opened her top drawer and dug to the back of it pulling out a dildo, it was a bit old and didn't vibrate anymore. She thought that wishing for a simple object wouldn't be harmful.
She held her stone and said "I wish for a nice new dildo which produces intense sexual pleasure when i use it."
little did she know the same wish was granted to Jon and he didn't hear it.
