It seems like wordpress is what you need, as it is probably better suited to long-form story content as opposed to what I'm familiar with, which is Tumblr.
Another avenue for Simmers who are more photographically inclined is Instagram! There are plenty of accounts called Simstagrams dedicated to posting Sims stories via screenshots, but this is definitely best suited for shorter conversation-type posts, as it is impossible to read entire narrations on IG. What is nice, though, is that Instagram can help you market your longer story-based content with snippets to a wider audience! Just an idea that I hope helps some!
