The close sisters 'Airi' and 'Wakana' were troubled by the noise of AV otaku every day. One day, 'Airi,' who complained directly to a man about garbage, was knocked unconscious with drugs and taken into his room. Wakana was also taken in the same way, and while in a sleep state, 'Airi' witnessed her being raped by a neighbor. Trying to escape, 'Airi' was instead raped herself. Afterwards, the two were driven mad by aphrodisiacs, consumed by pleasure, and fiercely fought over the penis.
