For the first time since childhood, I'm spending my summer vacation at my relatives' house in the countryside. It's a place where I feel isolated, with no friends my age, no entertainment like shopping centers or karaoke, and no cell phone reception. Minami-san, the beautiful young wife from next door, brings me some leftovers, and her exposed, sweaty skin looks sexy and defenseless, which arouses my desire. In the countryside, where there's nothing to do, a man and woman who are both conscious of the opposite sex are alone... A summer memory of them sneaking around their husbands and having sex whenever they wanted, day or night.
