A weekly magazine reports a case and the summer is "arbitrary". Yuto, a professional baseball player who returned to his hometown, meets a married woman, Nene. A gentle smile, a sweaty body, and a pair of ripe breasts the size of watermelons made in the field. Yuuto, who is being held captive, catches his eye. One day, Yuto takes an interest in the "unparalleled dick" and seduces Yuto. Sweaty fucking where a frustrated big-breasted girl and an unparallelled guy do not want each other in the countryside without air conditioning. No matter how many times they go, they still can't stop looking for each other.
