Chika, a member of a theater company, has been given the lead role in the next performance by the director. However, there is a rape scene. Having never been raped, Chika has no way of understanding the Kokoro pain of a victim, so she imagines rape when masturbating or practicing. The imaginary rapist attacks her real body. Before she knows it, the line between reality and dreams becomes blurred... she enters a territory that should never be entered... Chika plays the heroine who is raped. Chika is toyed with by a messenger of lust. Her supple body writhes as an extra-thick penis pushes open the opening of her vagina!
