Google has this URL in it's DB & look at the "Google Cache of":
http://www.japamor.com/sites/teen/teenblondefingering/
which would be whatever the default index page is on the server.
My guess is Google's trying to be "intelligent" about people looking for blah.com/ndex.html or blah.com/index.htm and defaults to blah.com/ if it has it.
