Great story, good premise, fine start, but it really needed more. It felt like something was rushed or left unfinished.
A refreshing one-shot about a women who finds a refreshing, and shy, man to go out with and recover from her terrible past experience with love. It's nice to see women being written like this as well; it's not just men who go for casual sex.
I really liked the idea of this story (because it's rare - the women in things are usually blushing virgins even after they've had regular sex...), but I think the story was just too short to do it any real justice.
I enjoyed it, but it could have been more fleshed-out.
