Nice one! You know I had a similar post the other day (diving accident). I wanted to find more than one pic, though, so that it would kind of tell a story. You succeeded, I didn't.
Another point - when is an "accidental nudity" pic an "ENF" pic? This pic would ordinarily classify as "accidental nudity" (nip slip) except that you have three pics, a story and a noticably embarrassed babe. Sounds like splitting hairs? heh, heh - One needs to decide what folder to put it in

My diving pic was accidental nudity (no noticable embarrassment), so I put it in "upskirts and downblouses" to be with the other nip slips, etc.
I have wrestled with this intellectual game before. Nip slips are accidental nudity unless there is noticable embarrassment in which case they become ENF's. At least that is how I see it.
