学校の夏休み期間中に開かれる秘密のスイミングスクール。少女たちはみんなプールが大好き。言葉巧みにダマし無防備な少女の裸体を貪りヤリまくる。未開発の未成熟な穴は種付けし放題。まだ何も経験していない少女達はアブナイスイミング指導で大人の階段を一段一段上っていく。A secret swimming school opens during the school's summer vacation. The girls all love the pool. He tricks them with his words, devouring the naked bodies of the defenseless girls and fucking them. The girls' undeveloped and immature holes can be impregnated with seeds as much as he desires. The girls, who have not experienced anything quite like this in their life, climb up the stairs to adulthood one by one with the help of these risqué swimming lessons.
