The anxiety and ecstasy of an innocent young girl. A schoolgirl wanders into a photo shoot attended by lustful adults, where her still-developing body is played with at will, her body and Kokoro defiled by a sticky mass of desire until she climaxes... That's right, this typical honor student, who has been treated as a "good girl" by adults and classmates since she was young, is able to fully unleash her "irresponsibility" that she can't say or show even if she wants to, in front of people who don't know her normal self.
