Rereading the Famous People thread, a thought came to mind...as much as this interest is kept secret by us, how many of you have let bits of this innocuously show in your real life? The most common example would be innocently as part of a Halloween costume but I'm sure there are countless other examples, where some aspect of belly or body or whatever inflation is innocently portrayed, one that could be easily passed off without highlighting a deeper interest.
For example, this was never used (no clue where to use it) but I designed an Escape Room/Puzzle Room based on Willy Wonka's Inventing Room. It was designed for other people to use, not me, but it included the plot device of Blueberry Inflation. It's not necessarily kink-related as much as I see it as using my knowledge of the genre applied in a more general sense.
