Exam in multiple stations- interesting idea. I like the friendly neighbor idea better but this is my second favorite.
First physical, unexpected physical, or more thorough/went further than patient expected. -too broad, and this is every story on here...
Neighbor - 3 I think this is broad enough to allow for several variations on the theme and different perspectives/stories to appeal to several different interests
Home visit- this is a lot of stories on here...
Friend or family member- this is pretty broad and a lot of the stories already on here involve this.
Mistress/Sub relationship/scene- too fetish specific
a very Unwelcome/Unwanted Chaperon - 1 interesting and could be a good prompt for a lot of different stories appealing to different interests.
Young lovers exploring kink and having an erotic experience in the outdoors! - not bad
A caring boyfriend/girlfriend/husband/wife or any other family member/close friend- too broad, and it is every story on here...
Comparing injection attitudes and experiences in youth- too specific to just one fetish and not enough broad appeal to get many entries.
