Favorite Breast Expansion Scenarios?

I'm doing some script writing for upcoming short films on my loyalfans involving breast expansion, and I wanted to see what you all find most appealing about the kink.

What are some aspects that make a certain piece of Breast Expansion media stand out to you?

I really want to put a bit more emphasis on story and characters in upcoming works, with a bit of plot thrown in, but also want to make sure the expansion/inflation parts really hit hard.
