Every story is, or should be unique. Although there can be a lot of very similar stories, each one should have unique qualities such as the author's perspective, and the kind of descriptive detail included. If this site contained dozens of stories all boiling down to, 'The Master caned his slave's bare bottom,' we might not be here.

Librarians would go mad if book titles were duplicated dozens of times, but there are books and also stories with titles like: 'Caroline'. I agree with fetish101 that authors should use more imagination in creating the title of a story. I would like the title to reflect some unique quality in the story. If the title itself is fairly original this makes it a lot easier to classify and find stories. The last thing an author should want is to write something with the same title as a well known, popular story. Making an effort will help to avoid this.

Some things to avoid are the use of a first name, such as 'Michelle,' and titles like: 'My first time', 'My ordeal', or even 'Submission'. Be careful to avoid using a single word as the title unless there is a very good reason.

First-time or inexperienced writers will often think that there is something unique about the theme of their first story, until they realise that there are actually dozens of very similar stories by other authors. That doesn't mean that each story has no unique value. What the discerning reader wants is a new perspective, some personal angle, or just nice descriptive prose that makes the story a pleasure to read.

Broadly speaking, most of the titles of stories on this site are unique enough. There are a lot of inventive titles. I still agree with fetish101 that effort of this kind is never wasted.

The title can have a hidden meaning. I have used the title: 'Checkout' for a recent story, and the true significance of the title will only become clear towards the end of the last chapter. Whatever the reader thinks it means will turn out to be wrong, but once the story is finished, readers will agree that it is the only possible title.
