Great story. How about a series on this theme? Maybe Keith and Sophie are more into their new bodies than the wife knew? Maybe more swaps happen?
I'll add it to the list of follow ups. I think I know where to take the story next.
Btw, if you check out Fictionmania, I have a number of stories posted there as Bashful.
Oh, I know your stories. I was actually going to ask "are you *that* Bashful?" c:
