Interesting this story. Sally KA has a mind set that is aligned to mine.
I have written a very similar story, including the AR disease. but it is quite long and has very little ABDL content. It is more an age regression to pre-teen with Wife as Mummy.
Not sure what to do with it at the moment. I had great fun writing it.
I notice that Sally has been influenced by some favourite stories of mine on fictionmania -- search author: Totok and read 'Peters' Girl' and 'Slip of the dimension'
My story is very much like Sally Ka's but in the vein of those two ohn fictionmania.
