Based on the erotic game by Bishop.

Yuuji, a second-year member of the school's art club, is obsessed with the female body and strives to portray its eroticism on canvas. He is a genuine pervert. To hide his peculiarities, he hides his eyes with his bangs and behaves as inconspicuously as possible, but this is not the case within the art club, and he is looked down upon by Tsugumi, a cool, busty beauty and junior member. After school, he is engrossed in sketching and ends up staying alone in the art room when Suzune, a classmate, comes to visit him. Suzune, a former popular child actress and a lively, busty beauty, is friendly to Yuuji and, as the conversation progresses, she agrees to be his model for his sketches. However, the moment Yuuji becomes excited by Suzune and contemplates the desire to see her underwear, Suzune lifts up her skirt. Realizing his mysterious power, Yuuji decides to dominate Suzune and Tsugumi. Yuuji pulls his bangs up, which he usually wears down, and disguises himself in a delinquent-like outfit, making full use of a power he calls the ability to control the human body. Though the two resist at first, they soon succumb to Yuuji's relentless sexual techniques...
