Des:The mother, Erika, and her son, Satoshi, divorced five years ago and became a single-parent household. The two end up living in Erikas countryside, but Satoshis shy personality makes it difficult for him to make friends. Satoshi is the only person who can soothe my heart. It was his mothers butt. Erika also begins to notice that her son, who touches her butt both when shes doing housework and when shes sleeping, is endearing to her and gradually brings her joy. Five years ago, the family was divorced, and her husband and wife were married to each other. However, when she thinks about it, she thinks that she has a beautiful buttocks.
