Sumire, the most beautiful girl in the neighborhood, will participate in the annual hot spring trip to strengthen the friendship of the neighborhood association. However, my father, who always goes with me, cannot go because of work, so this time I decided to go with him alone as a caretaker. The uncles in the neighborhood have known her since childhood, and the innocent Sumire has no sense of guard or anything. However, the ugly old men, who covet the mature appearance of a beautiful girl they have known for a long time, took advantage of Sumire's innocence and gradually began to sexually harass her repeatedly.
