During class time, Suzune Maihara was masturbating on her seat with her hands reaching for her crotch.
Her face showed shame, fear, and bewilderment upon indulging in bold acts despite her body moving against her will as if it was being manipulated by someone. Meanwhile, a male student smiled quietly as the sole witness of that scene.
The protagonist, Yuuji Kageura, has no outstanding merits and is so extremely transparent that his classmates can't even remember his face.
However, he realizes that he has a unique ability to manipulate other people's bodies at will then uses it by controling his classmate Suzune into masturbating during class to display his newfound power.
With this ability, he can play with the girls he has always admired and wanted to get.
Thus began the story of the poor flesh dolls being degraded into a prison of humiliation.
