Get what you need.

Cameron's three wishes were simple enough. He wished to be young and healthy, to never worry about money again and for the ability to get laid on demand.

With a puff of purple smoke his reality changed and Cameron awoke to find himself transformed into Cammie. Nineteen years old and a keen runner Cammie's petite body as certainly young and healthy enough to satisfy the first wish if not in a way Cameron might have expected. 

A flood of memories filled the new girl's blonde head and her eyes went wide as she realised she's rich. At least, her parents were, which amounts to the same thing in Cammie's book. Since her parents got divorced they've been competing to see who can spoil her the most. The part of her that remembered being Cameron muttered distantly about being a little brat but she was too busy think about the new Porsche asked daddy to buy her to pay it much attention.

As for the last wish, Brian, Cammie's new step farther, was on hand to take care of that. The older man may not be much to look at but he had it where it counts and Cammie had him wrapped him round her little finger. With him in the house and mom away on business so much a rough fucking was only ever a flirtatious smile away. 

 Altogether Cammie is pretty satisfied with how things turned out. The wishes may not given her exactly what she wanted but at least she'll never have to worry about getting what she needs again.
