Thanks guys! High praise indeed!
I would love to continue at some point. But time is an issue. I know there are still lots of unanswered questions, but it would take a short novel to answer them all, and I wouldn't want to rush. How each couple reacts to the other's sexual relationships and the long term implications of dating themselves are interesting plot ideas to one day follow. Maybe even the bikini could show up again. What if there were three Melissas? How would that change the dynamics?
I wanted to keep the story as realistic as possible. As it was Melissa's first time I didn't think she would be being too quippy with herself. That's the sort of thing that comes with experience. Sandra would have had more experience so the sex talk was raunchier. And you're right, it would have been good if I had the other Sandra and Melissa having an identical conversation at the end, but oh well, can't think of everything. Next time maybe
