My website has this story on it too: http://stories.kimintodarkness.com/genesis-of-the-slorg/
So... yeah. This is where the slorg became a thing. Looking back on it now I'm not actually that happy with a lot of it, but at the time I thought it was pretty balling and contained some nice concepts, as well as being much more interesting than most weight-gain-way-past-immobility tales you tend to find.
Be warned, contains sweat, belches and farts and stuff.
