College student Yuri Ando hears loud AV sounds coming from the room next door... Unable to bear it any longer, she goes to complain, but a naked man comes out of the room! The man drags Yuri in with his erect cock, and in revenge for interrupting her masturbation, he devours her body. Yuri is frightened, but to be honest, she also has a strong sexual desire and masturbates every day. It is not hard to imagine that such a frustrated Yuri would instantly succumb if she were to be violated by a sexually powerful man. "Such pleasurable pistoning...it's going to destroy my mind!" Yuri makes up an excuse and goes to the man again the next day and the day after...
