Katie watched as her 18 year old mother bounded out of the car with the exuberance of a girl looking forward to her first day of the summer. "Grab my stuff kiddo," kellie called as she grabbed her surfboard. "We've got a long day at the beach and I don't want to waste anymore time."
Katie nodded glumly as she fished Kellies bag out of the backseat. Glancing at the young 18 year old Katie marveled at her appearance. Kellie was a trim an athletic looking viral with golden blonde hair and a deep tan. Her breast size had decreased slightly but had become perkier. Unfortunately she saw katie as more of a nuisance than a sister and left her behind while she headed towards the water. Katie sighed wondering how much longer the regression was going to take before getting an idea. Digging into Kellies bag shequickly produced her license. Looking at Kellies license she could see that Kellie was now a month shy of her 18th birthday. As katie continued to look at the license she saw it change again. Kellie was now a month shy of 18 and the license was continuing to change.
Katie watched from a distance as Kellie continued to change. The 17 yearold girl had planted her surfboard into the sand and was looking around the beach looking for any cute guys. Unfortunately the beach was sparsely populated with a group of old women relaxing under an umbrella, two middle age couples eating on a blanket, and a elderly woman walking along the surf.
Kellie sighed as she went from 17 to 16. The young girl was sighed and looked back up the beach. "Hurry up katie," the teen whined. Katie suppressed a giggle at the sound of Kellies voice. It now had that whiny teenage tone to it. The teen had shrunk again leaving her only a few inches taller than her 12 year old sister. "Good like what took you so long," Kellie whined. "When I was like your age i could of been down here in half time and I didn't have any help."
"Sorry, " Katie said. "This tuff is kind of heavy." Kellie sighed and looked at her sister. "Just don't get in my way okay," withthat Kellie turned and and headed towards the water. KAtie took this opportunity to take a glance at Kellies license. Her had now turned 16 a month ago, Katie watched with interest as the license continued to change, today was now her sisters 16th birthday, as Kellie went from 16 to 15 Katie was shocked by what she saw. The license transformed into a blank piece of plastic with no information on it. Katie looked back towards the parking lot to watch the car slowly disappearing. From Katie's perspective it looked like someone was taking an eraser to the car starting with the roof. In only a fewseconds the car disappeared from existence.
"Oh no," Katie whispered. "How are we going to get home."
As Katie now thought about her current predicament she didn't here her sister sneak up from behind. "What you doing!!" Kellie yelled. Startled katie jumped and spun around only to be confronted by her 14 year old version of her mom. The girl giggled at her sisters response, brushing back her long golden blonde hair. "Scared you huh sis," she said with a smile.
Katie frowned and looked at the young teen. Kellie now had a young and innocent face that had lost all of its womanly maturity. Her breasts had been reduced to a pair of small Bs that seemed to rapidly diminishing. Finally the suit she wore had transformed into a girly pink two piece. "Why you scare me like that," Katie yelled. Kellie looked at her sister oddly as she became 13. "Oh lighten up sis," she sighed. "Don't be such a baby now come on are we voting surfing or what. "
"Katie watched as Kellies regression finished leaving her 12. The two girls looked incredibly similar with softball sized breasts and flare hips. Kellie was a little more girly than her sister with a bright pink swimsuit and was a half inch shorter than her sister but still you would of thought the two to be twins. Katie looked at Kellie in awe. This is what she wanted even if she had been a really mean older sister. That thought gave katie an idea. Should she make kellie even younger or enjoy her wish. Whatever she was going to do she needed to decide now.
