年に1度の夏休み。姪っ子姉妹が田舎の実家に遊びに来る。こんがり日焼け跡を残しても徐々に大人へと成長してきている。多感な時期を迎えた姉の「おと」と純粋な眼差しで見つめる妹の「ゆうか」は「おじさん大好き！」といつも僕を慕ってくれる。元気に遊び時折見える日焼け跡に動揺が隠せない。汗ばむメスの色香を漂わせ、無邪気に誘い、僕を狂わせる。あどけない姿に邪な欲望が目覚める。
Once a year during summer vacation, my nieces and sisters come to visit my family home in the countryside. They are gradually growing into adults, even though they still have dark tan lines. The older sister, Oto, is at a sensitive age, while the younger, Yuuka, looks at me with pure eyes and always adores me, saying, “I love you, Uncle!” I can’t hide my excitement when I see the tan lines occasionally visible as they play happily. They exude the sexiness of a sweaty female, innocently seducing me and driving me crazy. Their innocent appearances awaken my evil desires.
