When they got back to Jon's house after school, Jon told his mother that Karyn would be stopping for a bit and then they both headed upstairs to his room. They both dropped their trousers so that they could see each other's underwear, Jon grabbed his rock and said "I wish that Karyn and I were wearing our correct underwear." Nothing happened, Jon looked at Karyn "See? I told you, these boxers are mine" she said. "Let me try again" Jon said "I wish that Karyn and I would switch underwear."
There was a glow as the wish was granted, when they opened their eyes Karyn burst out laughing, while Karyn was wearing the panties, they looked big on her almost as if they were made for Jon's body not hers and she had to grab hold of them. Meanwhile Jon's boxers were too small for him and were stuck up his legs, embarrassed, Jon quickly dropped the rock and used his hands to cover himself up. "It's not funny Karyn!" Jon said, defeated he asked her "can I have my panties back please?" Karyn stopped laughing and handed him the panties while he handed her boxers back. Once dressed again Jon said "This is weird, it's like we've swapped underwear but everyone thinks we've always been this way."
"If you say so Jon-boy" Karyn replied "I guess we will have to leave it as it is until we can figure out how to fix it" "yeah I guess" Jon replied. Karyn stayed for the rest of the afternoon before heading home for dinner. After dinner Jon went to bed hoping that it would just be his underwear that had changed.
