The best way to send stories to other users is this :
1. click on the cover page of your story to open the READ IT page
2. Find the "More" link on the description of your story and click it
3. This will open the full page story for reading
4. go to the top address bar wile your story page is open and copy the URL (address)
5. You can now paste this into a message which is the direct link for someone reading your message to open your story. This can be sent in Messages as you use, or in Private messages (that little envelope icon in the upper right of their profile page.
Hope this helps./
Note Just know that because yhou send your work to people they are willing to read it or comment on it. Seems everyone has very little time to do this for others unless they are super interested in your work.
