Sensei no Mijuku na Seikantai

Overview

"I'm the type of person who can't draw what they've never experienced. Kurose, please, won't you show me how it's done...with your body?" Boys' love comic artist Mashiro only wishes to create romantic stories that touch people's hearts. So when his editor Kurose tasks him with drawing a sex scene for the first time, he finds himself in a bind. As unease fills his virgin soul, Mashiro decides to visit a shrine rumored to bring good luck to comic artists. But after he makes his prayer, a being possesses him... Instantly overcome with a surge of sexual desire, he starts coming on to Kurose! Lessons have begun for our talented yet crude editor and innocent BL comic artist-turned-seducer.
