Emiko Ejima is a dedicated housewife struggling with daily life. Her son Akira should have reached an age where he no longer needed it, yet he remained unable to wean himself from her breasts, clinging to his mother's chest every day. Worried about her son's future, she tried reasoning with him, saying, "It's time to move on from your mother's milk." Akira seemed to understand, but from that day on, he gradually became more and more listless. Concerned, Emiko went to check on him in his room and discovered Akira masturbating while whispering, "I want to touch Mother's breasts." Seeing how pitiful he looked, she gave in and said, "Just a little... you can touch them," exposing her breasts to her son.
