I don't want to have sex without love… But, because it seems like I'll die if I don't, will you be an outlet for my incubus impulses, Ms. Shinonome…?

Official English Translation

A secret was suddenly told to Aoba Ichijiku by his mother: "You are an incubus, so if you don't eat a woman, you'll die." He was confused, but he knew it was true because of the burning pain in his chest. So he uses his power to seduce the teacher after school.
