The beautiful and youthful mother of Fifty was having an affair with multiple men during her husband's overseas assignment because of her strong libido. The son who knew such a mother's behavior was very jealous. A son who devours the body of a fifty mother as long as a beautiful mother has a relationship with a stranger. A fifty mother who enthusiastically wets a ripe omako while refusing to be confused and raises a voice of joy. Drowning in a strong and intense forbidden pleasure that no other man can feel in fellowship with his son.
