Erika Itsumi, former vice-captain of Kuromorimine Girls' Academy, had her pride shattered in an unexpected back-alley hibaku. Powerlessly held down by the overwhelming physical difference, her uniform torn apart, and her body played with at will. But the real hell was yet to come. A photo of her face contorted with humiliation became the chains that would bind her forever.
"If you don't do as I say, I'll spread this photo all over the school."
With those words, Erika lost all means of resistance. She was summoned to a hotel room, where she was forced to change into lewd, slutty lingerie, shedding tears, and accepting the man's desires. Was this punishment, or a new beginning? Amid the endless abuse, Erika's mind was slowly seduced by a dark, damp pleasure.
