Searching for "Smart Phone APP Breast/Penis Growth" Series

[millionman]

All, I read this story recently and have attempted to run it down using tags along with a range of search terms with no luck. Essentially, the protagonist's best friend sends her a link to a new app that can alter breast/penis size and sexy things happen between the protagonist, the best friend, and her boyfriend. It's a pretty well written story and I'd like to see if the author continues the series. Any help locating this story is greatly appreciated.
