34-year-old Azusa is a married woman from the Kansai region who enjoys erotic activities with her husband's permission. Her imaginative personality is perfectly suited for erotic reading while wearing a remote-controlled vibrator. On the other hand, 32-year-old Yuka is a devoted wife who recently discovered, somewhat mysteriously, that she has a deeply masochistic side—this revelation has sparked her growing interest in erotic experiences. This is a highly sensual reading work that highlights the contrasting natures of the two women.
