Not new galleries, but some pics are in these that haven't been posted already:

Unless she has posed under another name, I'm not sure there is much more out there right now (free stuff, anyway) other than what has already been posted. As far as movies, her web site says there are movies, including masturbation.
KelseyXXX is so pretty, she is one of the few girls on the web who I can honestly say I enjoy looking at her clothed pictures just as much as I enjoy her nude ones.
