I know in internet explorer there is a way of right clicking on a text and one of the options is to translate into english.
It is done throught google and it is readable. Not perfect but readable. It works with webpages and text files.
I have traslated some spanish storys that were on the BDSM library from spanish into english. they were readable but they usualy had a probelm with past tence.
But it was understandable. Post your story on the library and Try the translater the worst you will get will be "germish" German/english
