Jon felt woozy for a moment. His vision cleared, and he was shocked to see that he was looking at...himself? His mother stood next to him. He did the math quickly. It could only mean one thing.
He looked down to see a pink sweater with two large, perky breasts poking out--his own nametag was there. Blonde hair cascaded down over his shoulders. He was wearing a pink plaid skirt with smooth legs and wedge sandals. He was in Sarah's body!
"Ew! Gross! I'm old!" Jon heard his mom's body exclaim. He figured Sarah was inside of there...it only made sense after all. Well, at least as much sense as bodyswapping could make!
"You'll be learning quite a lesson about responsibility and treating others with respect, young lady!" Jon's own body said, clearly his own mother was inside.
