778BMJ-004 Shimiken Sensei is surprised by the first erotic education Raichi Kurizuka Mina

Ero-gaku... it is a scholarly pursuit that compiles wisdom related to the body, life, and sex. Various Ero-gaku problems are tackled head-on by 'Shimiken-sensei,' renowned as the underground quiz king. Does an 'initial Ero-gaku' that the teacher doesn't know yet exist? A rookie male actor and three actresses are taught by their teacher through physical lessons in erotic knowledge. This evening's required course includes not only theoretical knowledge but also sex techniques on the bed, presented in Shikenji Sensei's new quiz-based erotic variety show!
