Kato visited Takao's house to show off his SLR camera to his best friend. Then Takao's mother, Fumiko, appeared in a hurry. "I won a trip to Hawaii in Fukubiki!" Fumiko, who had soared overseas for the first time, pulled out her old swimsuit and felt like a resort. Kato, who was watching the floating situation, asks Fumiko for a photo model. Fumiko was able to get on well and respond to bold demands ... The next day, Kato threatens Fumiko with the picture, puts on a more radical bikini, and begins to shave the hair that sticks out of her crotch.
