M no Joou-sama

Takeshi Saito, who lives a mediocre and unobtrusive school life, one day finds an S&M photo book and AV that his classmates gave him. He is then called by Itsuki Minagawa, the director of the student association executive department, who is dignified and strict and is also called the Queen of the school... She glared at me and decided that I couldn't help, but the words Itsuki gave me were too crazy: "Be my master." Itsuki was actually a masochist who admitted herself! She decided to educate Takeshi as her master in order to meet her own desires. [Translated from DLsite]
