Kaori remarried a year ago. Kaori has a son named Takeshi, who was bullied by her husband's children Akira and Ryo on a daily basis. Kaori, who is careful, is forcibly forced by Akira and forgives her body. Kaori is ashamed of herself, but remembers what she did and indulges in masturbation. Witnessing all of this, Kaori loves Takeshi, who laments her ineptness, opens her body and guides her son.
