I've published a collection of female muscle growth transformation sequences. There are twelve of them, and the collection is more than 120 illustrated pages.
Four of the transformations are at the extreme limits of actual female human muscular proportions, the other eight go at least somewhat beyond that. One of them has toon-style characters, the other 11 use more realistic 3D figures. One of them has male shrinking, the rest of them don't.
You can get your copy from the
Growth Comics store as a PDF, or for Kindle at
Amazon.com.
There are different versions of the cover, because Amazon doesn't like showing too much skin on a cover. The one on the left is from my store, the one on the right is Amazon. The interiors are otherwise the same content.
