This had the germ of a good idea, but sorry to say it was poorly written. I write this in hope it will help your future output. Avoid use of words like 'when' and 'then' - they stop the flow of a story.
Proof read your work before you post - Cindy morphing into Sarah was a terrible mistake.
A good story needs a setup, transition and a payoff. The setup was okay, but there was no sexual tension in the transition - sexual tension is what makes a story interesting.
Keep writing.
