A different start to the swapping

After making his wish Jon had no idea what he and everyone else were in for. Leaving his room Jon headed downstairs for breakfast. As he was walking into the kitchen he accidentally bumped into his younger sister Zoe who was headed for the front door.
“Hey watch where you’re going!” Zoe said to her brother as she walked past him. Little did she know that things had changed as she now sported her older brother’s lower half. Now below the waist she or he was clad in a normal pair of jeans some boxers and Jon’s old beat up sneakers. She had also gotten taller due to now possessing her older brothers legs as well as his dick. Vice versa Jon had shrank in height after gaining his sister’s lower half. He or now she was clad in a very different style of clothing. Now Jon was wearing fishnet stockings and a tattered mini skirt along with what used to be his sister’s panties. Furthermore although she had lost some height due to swapping legs she had regained it due to her current foot wear which were a pair of 6in stack buckle boots that were up to her knees. As Jon looked down she nearly fainted as she now sported what used to be her sisters lower half. However before she could react her sister left for school and her mother walked into the kitchen.
“Good morning Jonnie. Almost ready for school?” She asked.
“Ya mom.” Jonnie replied deciding to play along until he could fix it later. As for now she would just have to get used to having a female lower half Jonnie thought. However little did she know this was only the beginning and Zoe now had the curse of the half-and-half swap.
