START-419 Eng Sub. A Late-Marriage High School Teacher Who Loves Exhibitionism During Class Is Caught by Students and Reawakens Her Instincts.

START-419 English Sub. Teacher Yui, known for her strict and tomboyish attitude while always wearing sportswear, constantly scolds her not-so-bright male students. They secretly tease her, saying she probably has no boyfriend or romantic experience and has missed her chance for love. However, her true nature is very different: she has a strong desire and secretly indulges herself with daring acts during lessons and after school when no one is around, enjoying herself in private.
