"Uh, give me a second Kell," Katie said, walking off a few paces. She was looking around for the car. Then it hit her; she was fifteen, she couldn't drive yet.
"Well, that needs to be fixed. I wish I was sixteen and had all the knowledge and skills of a sixteen year old girl, including how to drive, along with my current memories."
Kellie's body didn't change very much, but Katie felt the effect on herself immediately as the knowledge of a sixteen year old filled her mind. It was a lot to take in, conflicting with her former innocent five year old personality. It felt like she'd simply woken up and had a gap of all those years with memories, but she still had the knowledge and experience she should have anyways.
She looked down and saw she now had a purse, and inside that purse was a driver's liscence, credit card and other things a girl her age ought to have.
Turning back to Kellie, Katie's new teenaged instincts started to kick in. A part of her felt responsible for thee newly regressed preteen, but another part was terribly embarrassed by her. Someone might see her acting like this maybe even a boy. Katie stopped.
She'd never thought much about boys till now, and some of the changes hadn't caught up with her, but the idea that a boy would see this petulant kid acting up was mortifying.
"Ok Kell, let's get you surfing. I some clothes just for you." Katie had to pat herself on the back. Kelly looked just like any average preteen, with a simple one piece bikini like Katie herself wore when she was 12.
"Thanks sis," The little girl said.
"All right. Let's go hang out," Katie said, taking Kellie by the hand and walking down to the shore. The ring was really making things interesting.
