Here are some links to other people's adult fanfic:
(I do hope to have more, but these are all the sites that I can link to,
so far.)
KAREN NICHOLAS'
FANFICTION ON THE WEB
(Karen's massive links site covers just about every type of fanfiction you
could want, from Adult Heterosexual
and Slash - that's same-gender sex to those of you who haven't heard the
term before - sites, as well as fan art and webrings, you name it!)
BARB
AND MARTI'S FANFIC PAGE
(This site has it's own pages of Adult, Slash and General Fanfic. It
is mostly Hercules, but they do have one or two
stories in other fandoms. They also have links to other fiction sites,
too.)
MORGAN'S ADULT FAN FICTION
LIBRARY
(This is one really GREAT site! Morgan does sterling work; she is a
dedicated writer, and I recommend a visit to her site, especially if you
like your fiction neat - that's without any dilutant, if you catch my drift!)
AFTER
HOURS
(This is a slash page which features Iolaus from HERCULES, with a smattering
of Methos, from HIGHLANDER.)
ORI'S
SINGULARITY
(This site hosts various fandoms, BEAUTY AND THE BEAST, amongst them.)
