It is described in great detail in the story, so I will not repeat that here except to point out that the design I described is only one of many variations. The basis for this story is a life-long passion I have had for sensuous female clothing. Through the Internet I have gained much comfort in knowing that there are many people who like me enjoy fantasies and even enactment of fetishism and extreme sex play, including erotic tickling. What goes along with that knowledge is my acceptance of the fact that my own favorite twist, women enjoying the delightful torment of clothes that tickle them to the limit of their endurance, is a highly unusual infatuation. It is that rare.
Special mention needs to be made about the age of the central character.
Shelly encounters, but the truth is that I simply wanted to deal with a young woman's first encounter with unfamiliar and relatively extreme forms of sex. Sixteen is not a magic number, it just seemed to be the best age to choose to make that point, because most readers will ascribe a quality of innocence to her that might be lost if she were any older. If sixteen is too young for you to feel comfortable with, make her whatever age you wish. In order to make the story sound more realistic I have included dialog based on Pidgin English, as well as some Hawaiian terms related to hula. I tried to keep it simple and provide sufficient context so that little is lost if you are not familiar with the dialect.
