Jon smiled as Karyn stopped down to visit him the next day.
"Do you want to try a wish today" Jon said as he handed Karyn the stone.
"Sure" Karyn said as she held the stone. "I wish my mind was in Jon's body."
Karyn expected a body swap, her body slumped down as her mind transferred into Jon's body. She looked down at her body and smiled. Then heard words excape her new mouth. "oh my god, Karyn, you're in my body."
She gasped, they were both sharing a single body.
