A few hours from the city is an island where life still moves at an old-fashioned pace. After failing the college entrance exam, depressed NEET Hiroki Ayase needs a change and arranges to stay with busty Yoriko Ohba and help her out working at her guest house. The married Yoriko is sweet and proper, but Hiroki's always had a crush on her... and one day, her neighbor Fumie catches him sniffing Yoriko's panties! Fumie tells him the island still practices the ancient custom of night crawling, and tells him if he's so horny he should crawl into Yoriko's bed at night... or hers. To Hiroki's surprise, Fumie really is waiting up for him and takes his virginity. But it turns out Yoriko isn't as sweet and innocent as she seems...
