Young Jane Stalwart 2

 Assume any nudes are now Jane with a full-grown woman's body (ie of legal age). I tried to do breast expansion and clothes hanging off her in tatters or her new body bursting out of her clothes

but had a lot of trouble. A few she's hefting her new bosom as I imagine a young tomboy wouldn't be happy or used to the added weight

Young Jane Stalwart

 15yo Jane accompanied her father on an expedition to Norway c1925. While exploring a cave located near an ancient ash tree, she stumbled up a passage and lost her footing, sliding down she fell into a a vril-infused pool believed to be the well of urdr from Norse legend. She fell in a thin scrawny teen and emerged a full-figured grown woman. Technically she ends up with a C-cup. Later, she and Patty bathed in the well of Ymir and her cups turned to DD as well as her latent psychic power emerging. The Cock of Osiris would increase her breasts once again.
