The story actually has hit a logical ending point, as several have pointed out to me (in a positive way). It was an experiment in writing parts of a story and showing them as they completed (like Tuck or similar) but that proved to be a very painful process because my time to write is often very limited. So, in short, I don't really know. I guess it depends on whether or not what I have to add has value for the story or not. If it does, it will grow.

I do know that any future stories will be self-contained, the Presdoh series notwithstanding. Mostly because the latter has encapsulated stories that allow me to enter, write, and move on to other things without losing the thread, more like episodes in a TV series.
