Like the title says, I'm curious if anyone else's interest in this fetish goes through high and low phases, where they may lose interest in it for a while before coming back to it. Personally, I spent a lot of time with this fetish in my late high school/early college years (especially blueberries), but after a while, I realized that it wasn't doing much for me (especially compared to my fat fetish). It's only now, two years after graduating college, that I'm starting to get reacquainted with this fetish.
Around 1990s I have seen an asian animated series with belly expansion like Wicked's scenes. I'm not sure that animated series is from China or South Korea.
