Yumi Kawai is a 55-year-old milf. A few years ago, on a night when her husband was away on a long business trip, overwhelmed by loneliness, she ended up sleeping together with her son. That night, her son's hand slipped into her embrace. At first, his hand touched her breasts, but gradually moved downward, slipping inside her underwear. My panties became completely soaked from the affection I received from my son during those lonely nights without my husband. Eventually, I accepted him as a man. From that night on, whenever my husband was away, I began a daily affair with my son.
