Northpole.Com has some (non-religious) Christmas stories that can be read aloud, on most of them the "next page" button stays in the same spot, so you can put your mouse pointer over it and have switch users turn the pages.
Note: for some bizarre reason the sound on these is not working in Firefox on my computer, but does work in Internet Explorer, so if you aren't getting sound try a different browser. Wait... I reinstalled Adobe Flash Player and now sound is working! So quick tip if for some reason you suddenly loose sound in Firefox, reinstall the
Flash Plugin.
