In order to make the patients a bit less apprehensive about a special treatment enema, they are scheduled to see a film of the procedure so they will understand exactly what will happen to them. A suitable model is needed to role model the patient in the training film. Our heroine has been selected from a set of interviews and physical examinations to be sure that no medical problems exist which will cause trouble with the filming of the intimate medical procedures.
Many may write a story and just leave it for what the first presentation was. Good story writing often means revision and more revision to clear up the details and fill in missing links to tie the story into a far better flowing read. Some here may have noted that while not much new material may have been added at the ending, but many times there have been modifications within the body of the story to make for a far more interesting read. One never knows where the changes have been inserted, but that is all part of the fun with writing fictional work and reading the results. Often times new ideas happen in the creative mind and they need to be let out as part of the improvement of the original presentation. Perhaps only a few words here, a new sentence or two there and sometimes a whole new paragraph to sweeten the deal.
