’春の風が吹くたび、隣を歩く先輩から、甘いシャンプーの香りが鼻先をかすめていく…幼なじみの七緒先輩と、1つ年下のボクは10年以上もこの道を一緒に学校まで通った…家族ぐるみの付き合いでお互いの家にも気軽に行き来する姉弟のように無防備で親密で一緒にいるのが当たり前の関係だった…。何でもない坂道でつまずき、顔を赤らめる七緒。そのふんわりとした頼りない姿を見るのも、あと数日だけ。大学の推薦が決まり、この街を出ていくことになった七緒との距離が少しずつ遠くなっていく…その現実が、ボクの胸を締め付けていた。七緒は他校の男子から告白されたらしい…でも、「告白、断ってきたんだ。私……ずっと前から、大好きな後輩がいるから…」ボクのことが好きだったと打ち明ける七緒…。ボクも一途な想いを伝え、お互いに高まる性衝動を抑えきれず、身体を貪り合う！部屋に響く秘めやかな吐息。階下に母親がいるというスリルが、二人の感覚をさらに過敏にさせていく。大人びた表情でボクを翻弄していた先輩が、次第に快楽に身を委ね、甘い声を漏らしながらボクを強く求めてくる。二人は引っ越し直前まで何度も激しく身体を重ね合った。迎えた旅立ちの日…切ない別れを惜しみつつも、再会とお互いの若い欲求を約束して、七緒は新生活へと向かうのでした。’

Every time the spring breeze blows, the sweet scent of shampoo from my senior walking beside me wafts past my nose… For over 10 years, Nanao-senpai, my hood friend, and I, a year younger, have walked this road together to school… Our families are close, and we visit each other's homes freely. We were as vulnerable and intimate as siblings, always together as if it were the most natural thing in the world… Nanao stumbles on a simple slope, her face turning red. I'll only be able to see that soft, helpless figure for a few more days. With her university recommendation secured, Nanao will be leaving town, and the distance between us is slowly growing… This reality was tightening my chest. Apparently, a boy from another school confessed his feelings to Nanao… But, "I turned him down. I… have had a junior I've loved for a long time…" Nanao confesses that she's always liked me… I also express my sincere feelings, and unable to suppress our rising sexual urges, we devour each other's bodies! Secret sighs echo in the room. The thrill of having her mother downstairs heightened both of their senses even further. My senior, who had been toying with me with her mature expression, gradually surrendered to pleasure, letting out sweet moans and strongly desiring me. We made love passionately many times right up until the moment of departure. On the day of departure… while regretting the bittersweet farewell, Nanao promised to meet again and satisfy each other's youthful desires, and headed off to her new life.
