It is night. In a lonely house, standing on a hill in the middle of the sea, the lights are off. In the darkness, only two silhouettes can be seen. One is a naked and bound girl, and the other is an older man with a spark of madness in his eyes. The man force-fed the girl pills and then hooked a vibrator into the "game. It was obvious that the drugs had long ago taken effect and the girl's desire was so high that she was begging the man to do whatever he wanted with her. Naturally, the "madman" did not turn down the opportunity. In the morning it turns out that the man with the crazy look is the owner of an entire estate and the main character works for him. Itami, which is the name of the protagonist's master, has business to attend to and must leave the estate for a week. He entrusts the care of his wife and her sisters to Hashizumi. As soon as he leaves, the protagonist gets a headache, but Itami's wife, Toua, hands the guy some headache pills. After trying one, the hero is surprised at how quickly the headache goes away. The two sisters intervene in the conversation, insisting that the servant is looking too closely at his mistress. He may even be thinking all sorts of obscenities. The boy excuses himself and tries to make a joke, but the girls press him very hard. Soon two more girls enter the conversation and passions get very heated. It turns out that the mother of all these girls is gradually going crazy and only talks to Toua. All this makes the guy's head spin...
