https://www.patreon.com/omnipotenceThe author has begun a Patreon page. People who pay through Patreon receive a slight discount on Tokens and access to her Production Blog. At higher levels, you get access to the Suggestion Box (likely to be implemented on January 1, 2018) and, at the highest level, free previews of stories. (Final stories will not be free, however.)
Most of her stories include at least some breast expansion, though it is generally not the focus of the story.
