Yuriko Takazono, a woman in her fifties, sexually assaulted her friend's mother. (AWD-152)

Yuriko, a woman in her fifties with a beautiful face and full breasts, is a woman with a strong sex drive. Even though her son's friend lives there, she still indulges in masturbation. Her son, Yuta, lets his friend, Akichi, witness his mother's obsessive behavior, and he also engages in lewd acts with his mother, boasting about it to Akichi. Akichi, intensely curious about the forbidden relationship between mother and son, takes advantage of Yuta's absence to display his desire to Yuriko. She allows the young man's penis to enter her mature body, driving her lust wild with pleasure.
