ive been looking for games or books. honestly just throw anything you think is intresting at me i will read it or play it
for pregnancy I can only recommend Preggopixels’ Seeds of Destiny.
For breast expansion there was a little arcade game called breast Quest I found.
As for books i have no idea what those are I cannot read
That is a wide array of fetishes, there are the normal tags to search on the site of course. #weight-gain, #breast-expansion, #ass-expansion, #inflation, #pregnancy. That might help you discover somethings/narrow down your search.
Outside of that I have a list put together for games I have played and would recommend for weight gain. Krod’s weight gain games recommendation list - Projects - Weight Gaming. It also has loads of tags on it while the games on it are largely WG focused there are some that include other fetishes like BE, AE, Preg, etc, and are labeled as such.
Hellbrain has a few good pregnancy/expansion focused games.
