Sensei, Ore ni Kamawazu Itte Kudasai!!

Twenty-six-year-old manga assistant Mamoru Ashida is too skilled for his own good. Due to his habit of overworking, the authors he works with soon become lazy and complacent, leading to him eventually being fired. Struggling to find work, Mamoru resolves to turn things around when editor Kasumi Mashiro, his former classmate, tells him to work for her little sister Madoka. But as he enters her room, Mamoru sees an absurd sight—Madoka is masturbating while drawing!

Madoka explains that she can only draw well while touching herself, which deters any assistant from working with her. Believing he has no other option, Mamoru agrees to become her assistant. With every climax and finished manuscript, a strange yet close relationship develops between the peculiar artist and her reliable assistant.
