Reiko Sawamura is a milf who, after her husband left, devoted her life to raising her son, Hiroaki, seeing it not just as a duty but as her deepest desire. Even as Hiroaki grew, Reiko continued to protect him. However, Hiroaki grew resentful of being treated like a child and began wishing to support his mother with his own strength. Gradually, these feelings transformed into romantic love for his mother. One day, using money saved from his part-time job, Hiroaki gifted his mother a two-day, one-night hot spring trip. This was more than just a present—it was his way of expressing his true feelings.
