Widow Shoko continues her daily life living in public housing with her son, always enjoying warm and peaceful days. However, one morning while seeing her son off to school, a young man working for the cooperative suddenly appears. Feeling a man's body for the first time in ages, Shoko is captivated by his strong, muscular build, and naturally drawn into his arms, leading to an intense relationship. The next day, she takes her son to a public restroom to help him urinate, when a laborer appears, his mature cock immediately catching her eye despite her child being present. Several days later, filled with quiet anticipation, Shoko is once again seen heading back to the public restroom.
