Laura S. Fox, in 19 Days. 05/01/2018 (Updated: 06/07/2018)
I wrote Nude Pics Please! for the 19 Days by Old Xian fandom. 19 Days is a really cute Chinese manhua (the Chinese word for comics) that follows the adventures of a group of teenage boys. To give a little bit of context for anyone who didn't read the manhua, the characters starring in my little fanfiction piece here are He Tian and Mo Guan Shan, two boys who are sort of in a cat and mouse game.
This story starts after He Tian sends Mo Guan Shan a dick pic to tease the guy. The characters are aged up, so they are in their last year of high school and of legal age.
