The first time I read about ageplay was in books that described adult women being treated as children, dressed like small children, spanked, taken care by nannies, all for the pleasure and sexual use of their 'daddies'. Much later I was introduced to the age regression world but unfortunately most of the authors couldn't write a good story in reasonable English. (This world was also drawn into a series in Palcomix).
As most of our delightful kink, there is as many versions of the ageplay section of it, as is of authors and role players, including all the variation described by the posters, but my understanding of ageplay remained - possibly because that was my first insight into the theme - with the adults reduced to children, getting spanked and ravished by their 'daddies'.
