This role-play is performed by adults. Student ``Kameda'' always hangs out with his good friend ``Hosoda.'' One day, Nanami, who she has a crush on, comes to a study session at Kameda's house with her best friend, Yui. ``Hosoda'', ``Yui'', and ``Nanami'' stay at Kameda's house to pretend that their parents are away on a trip. That late night, Hosoda shows Kameda's erotic goods to two girls, and the four of them get into a lewd atmosphere... Their unrequited love becomes distorted by the excitement of orgy and netorare sex. #YoroP
