It's been 20 years since I got married... My son, Keita, has reached adulthood, and Sayuri is patting her shoulders saying that she has fulfilled her responsibility as a "mother". However, Sayuri's calm daily life is easily destroyed by a "certain incident". One day, Sayuri is raped by Kobayashi, a newspaper delivery part-timer who should have been her friend, without knowing why. When the wounds in her heart had healed... the stimulation of Kobayashi's cock carved into her body transformed Sayuri from a "mother" into a "woman"...
