There are right click disable javascripts, but it is impossible to disable someone from viewing the source code to your site. Even for an Iframe, they can track down the page that contains the code and view the source.
Code:
<p class="blahblahblah">Even if the text looks like this</p>
<br />
<h1>You can still figure out a way to delete the tags and copy it</h1>
You'd have to use some sort of plugin, ie flash, silverlight, java where the text is not selectable and the source code is invisible. Even still, the user can take screenshots and if they really want to they can transcribe it.
Long story short, if anyone can read your stories, they can copy them if they really want to. The amount of protection you put up just makes it more annoying to do.
