催眠即ヤリ学園 勝気副会長・肉便器調教編

The protagonist, Yuzuru Kusaka, is an ordinary, timid high school boy.
The only thing notable about him is his neat handwriting, which landed him the role of student council secretary.
Under the guidance of the beautiful, gentle student council president and the sharp-tongued, strong-willed vice president, he’s essentially become their errand boy.
Though he resents it, he secretly harbors feelings for the president, so he puts up with it.
