I’m sure many here are aware of the healthy amount of pregnancy lovers on DevinatArt, but I found a gallery of, between the favorites list and posts, has several hundred bellies that seem to have been carefully picked, there’s some classic and a lot of new stuff and was a joy to look through. It’s heaven!
