The movie consists of three parts with Mako playing the main character in each part, rural girls being lustful in the hot summer days. The first part is a childhood friend who has just returned from Tokyo. The second part is someone born and raised here with Mako. The third part is a handsome and stylish senpai, whom Mako secretly loves and has just returned from the city. But all cannot resist the beauty of Mako in revealing, sweaty clothes, and shiny skin. Both indulge in each other, licking every drop of sweat on each other, enjoying the sexual pleasure to forget the scorching heat of this summer.
