The close sisters Airi and Wakana are plagued by the noise of AV nerds every day. One day, Airi complains to a man about the trash, and is drugged and taken into his room. Her younger sister Wakana is also taken in the same way, and when Airi witnesses her being raped by the neighbor while she is asleep, she tries to run away and ends up being raped instead. The two are drugged and have sex, and are consumed by the pleasure of the drug, fighting fiercely for his dick.
