12 Transformations is a series of graphic novels where Growth Comics presents a specific type of growth in a dozen separate sequences. This issue is about Breast Expansion. Almost 100 pages long, it contains one 27 page story called "The Lift", about an elevator that changes the size of women's breasts, along with 11 other breast expansion sequences. Some of the sequences are somewhat story-like with dialog, while others are art renders of women's boobs getting bigger with no dialog. Most of the size changes result in very large but realistic (i.e., possible in the real world) breasts, though a couple go beyond that. "The Lift" is arguably in that category, featuring an athletically built women growing a pair of boobs somewhere around an M cup, while remaining fit and trim everywhere else.
