Nobuhiko's next door neighbor Anna is a kind-hearted Brazilian woman who doesn't shy away from showing off her amazing figure. Much to his dismay, however, Anna is married to a short old man who looks more like her grandfather than her husband.


While returning from his part-time job, Nobuhiko notices Anna's husband accidentally drops a wallet with five million yen inside. Without hesitation, he calls out to the old man, only to be told that this was a test! The old man invites Nobuhiko to his house, and ends up asking him a very personal and strange favor: he wants Nobuhiko to sleep with his wife Anna?!
