Actually, from the description it sounds like one of the Growth commissions Lorekeep was having done (or trying to have done) for his earliest packages. It was going to be something like that story "Plaything", with some guy getting possession of a little fairy/doll thing (whose name did start with a "z") growing when it ate or sex was involved, etc. Unfortunately, it never got made, or at least not to the point that Lorekeep was able to do anything with it, and I know it passed through the "hands" of at least 2 different artists. He simply had the one promotional image of the fairy-esque girl looking pissy and sitting in someone's hand, which shouldn't be too hard to dig up.

Are you talking about the Plaything Poser work by Voluminous? I know there are different versions of the story out there. The one I have starts with a scientist in a lab with a tiny woman in a tube and she grows a little. After the fade out, she's on a hospital bed (about 15-20 inches tall). She goes through several small growth spurts and such.
