In search of something out of the ordinary, Takahashi Koichi and his wife set off on another trip today. She's 42 years old, a veteran housewife who's been married for over 20 years, and has two grown children. She takes lessons and lives an ordinary but happy life, but... on the train to the hot spring resort, her breasts are squeezed and she is trained with a remote-controlled vibrator. At the botanical garden, she is trained with a remote-controlled vibrator in front of tourists, and her ass is caressed. Her obscene ahegao face is irresistible. At the inn, they have sex in the open-air bath, and he penetrates her big ass!
