[JUR-378] "My mother-in-law will teach me how to kiss an adult ..." A plump mother-in-law who takes away the lips and virginity of her innocent husband's stepchild Mariko Koto

Mariko decided to marry a man who has a son who refuses to go to school. Her husband's stepchild, Yusuke, did not recognize Mariko, her father's remarriage partner, as her mother, and kept her distance even while living together. Mariko, who wants to deepen her relationship with Yusuke, admonishes her to support her as a family and mother, and Yusuke gradually begins to open her heart. However, Yusuke's truancy has not changed, and when he hears the story, Mariko is told that he has failed in his relationship with a woman. In response to Yusuke's request to know the woman's body, Mariko gently guides Yusuke, saying, "My mother will teach me from the kiss of an adult first."
