Hikaru, a female student, visits the home of her shut-in classmate, Masao. Masao's house was not popular, but it had a strange atmosphere. Frightened, Hikaru turns on her heels, but Masao is standing there, and the two exchange a conversation. However, Masao pressed Hikaru, saying, "I just wanted to fuck a woman." It doesn't stop there, but one after another, seniors appear and participate in the act. In addition, a yakuza man who claims to be Masao's father also appears and teases Hikaru's innocent body and heart.
