Leaving their parents, sisters Miyu (Inaba) and Kana (Nagi) live together harmoniously. Their neighbor Sato stares at them with lecherous eyes. One morning, Sato targets Kana when she is alone and approaches her. 'I have something I want to show you,' he says before forcibly taking a reluctant Kana back to his home and raping her. However, this is not enough to satisfy his desires, as Sato's lust also turns towards Miyu.
