weekend. Shintaro, a hard-working young office worker who lives with his wife somewhere in Tokyo, hastily cleaned up the room in order to welcome his wife's mother, who will be visiting soon. The wife's mother, who lives in the countryside, travels a long way to Tokyo by train to see how her daughter and her husband are doing. She heard the chime of the door chime, and her son-in-law couldn't help but gasp at the sensual swelling of the female body of her mother-in-law, who soon entered the room.
