I love my sister!My relative's older sister, Natsu, has always admired me since I was little.The person who was waiting for me when I returned home during summer vacation was someone who was truly kind, dazzlingly beautiful, and who was my first love.Eating watermelon, cooling off on the porch, wearing a yukata and enjoying sparklers...I can't stop my heart pounding at her casual gestures and transparent sweaty skin.One day, one day, someone saw me with an erection in the bath, and Natsu-nee-chan smiled and took my hand, saying, "It's my fault, isn't it?"After that, in the bedroom, in the Japanese-style room, on the verandah...I hide from my parents and cum in close contact with them many times!Before I knew it, my mind and body couldn't be separated from her...At the end of summer, the words we swore under the sparklers: "This summer will be a secret for the rest of our lives." Unforgettable memories of a forbidden summer that only we know.
