I don't really know sites that you have to pay for to recieve written erotica. Seems kind of silly to me since there is so much free stuff out there.

I am talking about works just uploaded to sites for anyone to read for free. Of which there are many sites. One of the biggest with thousands of stories (80% adult stuff) being uploaded a day has been around for at least 10 years since I first saw it.

Of course I wouldn't be able to prove it since that would violate site rules, but a simple google search for written erotica sites would do.
