Katie knew exactly what she was going to do.
"I wish that Kelly was my 14 year old twin sister. She thinks we snuck her through by pretending we were older than we are and we share everything together. I also wish her clothes would change with her."
No sooner did she say it, Kelly began to change. Katie, watched fascinated as her mother's adult features began to fade away, replaced by those of a gangly teenager. More and more highlights weaved through her blonde hair as adolescence betrayed her skin and pimples dotted her face. Her arms and legs were lanky as her breasts continued to diminish. Kelly of course, went on about the movie, talking like an excited teen, unaware of her change.
Katie continued to observe, spellbound as the pimples and signs of a teenager began to fade as Katie dropped to a fourteen year old. Freckles began to reappear as her chest flattened and hips became boyish. Her clothes shrank and changed to those worn by a young teen. Then Katie saw something that both terrified and made her amazed. Kelly's face and features became her own, right down to the subtlest detail.
The young girl realized that the magic had reinterpreted her wish about making them share everything! Kelly was now her identical twin!
