After enduring daily harassment from the stepfather she despises, Kurumi is raped and creampied while her mother is away. She believes her beloved adult brother will save her, but his obsessive feelings for his adult sister take over and he rapes and creampies her too. Her desperate pleas go unanswered as the two men subject her to a domestic gangbang, driving her from despair into an even deeper hell.
