mother's friend

``Today, my mother's friend is coming to stay.'' ``If she's a young woman, that's fine, but if she's my mother's friend, she's probably just an old lady.'' Goro, his son, goes home without hesitation. However, the person who greeted him was Hotaru, a beautiful mature woman of a certain age. Goro is captivated by her beauty and spends a sleepless night with stress. When he leaves the room for a change of pace, he happens to see Hotaru masturbating. Excited, Goro could not contain his desire and showed his erect penis, seeking Hotaru's body.
