The legendary group series that led Japan's hidden camera boom returns with its 9th installment! This time, the star is Chisato, a girl who looks just like Koayu Yūko. Though she normally speaks standard Japanese, she naturally slips into Kansai dialect when aroused. Beyond her charming appearance, she's deeply addicted to sex—so much so that when kissed, she unconsciously grabs the man's crotch hard with her other hand. Her pale, smooth skin flushes with heat as she engages in intensely passionate, rough-style lovemaking.
