Miko Shibari

Takuro is a high school teacher. He likes Miko and is a tie-up mania. One day, he receives a parcel from a friend of his. It's a rope with magical powers. He plans to use it immediately, and finds his targets, Kanae, a female teacher, and Yuka, his student. They are sisters from a small shrine, and allowed to wear Miko uniform as campaign girls for tourism, even at school. Perfect timing for Takuro...!
