I'm a professional writer with an (completely normal!) obsession with breasts getting bigger. I've been writing Boob Note and Expansion fiction for over a decade now. My time I can devote to it is directly related to my Patreon...
Things have been pretty quiet on the DA front, but it's mostly because I tend to be self-critical. Not in a lack of confidence, but because it's hard to read what people want and when. So, honestly, the number one way I can motivate myself to write faster? Toss me some feedback! Comment on a story, like a comic, letting me know what you like and why is no greater motivator.
That said, please consider making a small monthly pledge if Boob Note (and my other works) staves off your boredom and it allows you to have a clearer influence on what I make and why.
Donating also gets you insight on my work. I have a 'Space Bear Lair' where Patreon donors (even those that donate as little as a dollar) can stop by and say hi.
Yes. Fanfiction is a continuation of an existing story or existing characters in a different setting (without an official connection to the real story, hence the fan part). A tribute piece is reconstructing a story based on its elements or themes. Using the name basically makes it fanfiction by default.
Boob Note is a tribute story because it's just borrowing the concept of a magic notebook.
If the story was about someone that found Kira's death note, but only used it to expand boobs that would be fanfiction.
