The story is about a science professor who marries a woman with two daughters (Marina and Airi). The woman had gotten divorced a few years back and now she is happily married with this younger man. However, while Marina accepts her new stepfather, Airi does not and despises him. Of course only if they knew that he in fact is sexually obsessed over his new daughters, pervertedly sniffing their underwear and planning on raping them by using an aphrodisiac spray he developed, in turning them into his personal sex-hungry sluts. But first he tests his drug on Sana, a friend of Airi who quickly became obedient to his needs, which he starts videotaping Sana doing indecent things. Airi eventually finds out about the videotapes and confront her stepfather. When Airi comes home and notices her schoolmate Sana giving him a blowjob, he sprays the drug on her. Now he will do with them whatever he pleases. Now she becomes his, and from that point on her stepfather starts having sex with her. Next, her stepfather aims to her sister Marina to become his personal sex-hungry sluts.
