A weekly magazine reports that a case and summer are "arbitrary". Yuto, a professional baseball player who returned to his hometown, meets a married woman, Nene. With a gentle smile, she is drenched in sweat and has breasts as big as watermelons made in the field. Yuuto, who is confined, catches his gaze. One day, Yuto is intrigued by the "unparalleled cunning" and seduces Yuto. Sweaty sex in an area with a frustrated large-breasted girl and an unrivaled guy in a non-air-conditioned countryside. No matter how many times they go, they cannot help but seek each other.
