The fifth installment of the "Innocence" series features Shihosan, gradually being drawn into a more depraved world. Her sensitive body reacts intensely, becoming increasingly aroused. Despite her humiliation and shame, her physical responses are uncontrollable. Even as she's tormented, her pleasure continues to build. Under the men's relentless assault, Shihosan reaches orgasm quickly. Penetration follows one after another, pushing her to climax repeatedly—over and over, countless times. Shihosan has now become so immersed in this abnormal world that she can no longer feel pleasure from ordinary sex. Her body and mind are forever changed, unable to return to normal.
