There's so many tropes I love when it involves unwanted or forced expansion. "Careful what you wish for" scenarios, or shy girl growing bigger and not wanting attention, etc...

It's hottest when the girl is already decently huge, and she starts growing uncontrollably bigger with absolute terror.

It's the thought of knowing how hard a girl struggled previously to gain confidence in her already large chest. Then suddenly, BAM, triple her boob size with a lingering fear of expanding whilst dealing with the aftermath of having a Venus body.
