女郎蜘蛛～呪縛の牝奴隷達～

A guy got a part time job with a very strange family. During the daytime, he can explore the house or sort documents. During the evenings, he gets to play rope tricks with the mother and two daughters. If he can survive and find out what's going on, he might end up happy with one of the girls. [From Li's Fun House]
