『Graduated Mother』 refers to a woman whose child has left home, whose parenting is also settled, and who has finished her role as a mother and graduated. Whether it's a son or a daughter, without distinction! "From now on, I'm going to live freely as a woman." A serious mother, rewarding herself with SEX, removes her limiters with the sense of liberation after finishing child-rearing and indulges freely, getting completely out of control!!!
