I'm not sure what to say. Some (a big part) of the S people I know don't like to read any kind of book (but I don't think that the S is to blame for that, but more their own mentality).
On the other hand, my ESTP sister likes to read both fiction and nonfiction. And I know some other Ss who like to read fiction as well. There are some who would more likely read nonfiction as well.
My S friend loves fantasy fiction, it must be based in some kind of wordly lore/history though, like The Mists of Avalon, or The Clan of the Cave Bear. If it's too fantastical and out there she just won't enjoy it.
None of my other S friends, or family, read at all.
Not really into fiction. Fiction series are easier to get into, probably because it establishes a more "normal" feel, just from repetition alone. In other words, it feels too other-worldly on the first read, but after getting used to it (as in a long series) that doesn't really bother me much.
