Her husband died early in an accident, and Ms. Kitagawa had to raise and teach her son who was in high school alone in the hope that he would have a good future. Because she has to take care of her children alone, and she still has a teaching job at school, she often feels tired and extremely emotionally deprived. So deprived that when her son invited her friend to study with her, she always had sexy and stimulating expressions and even crushed her son's friend to rape and satisfy her burning sexual craving for a long time. And yet, every time he came here to study, he once again became a sex slave to this lewd teacher. Although he knows that, the curiosity and excitement after each time he has sex with your mother is the motivation for him to come here more regularly. What a lucky student.
