秋が終れば冬が来る　ほんとに早いわ
夏休みには二人して　サイパンへ行ったわ
日焼けした肌まだ黒い　楽しい思い出
来年も又サイパンへ　泳ぎに行きたいわ

あなたは優しい人ね　私を抱きよせて
ずっとこのままいようと　KISSをした

私がオバさんになっても　泳ぎに連れてくの?
派手な水着はとてもムリよ　若い子には負けるわ
私がオバさんになっても　本当に変わらない?
とても心配だわ　あなたが　若い子が好きだから

そんな話はバカげてる　あなたは言うけど
女ざかりは　19だと　あなたがいったのよ

だけど何くわぬ顔で　私を見つめて
あれは冗談だったと　KISSをした

私がオバさんになっても　ディスコに連れてくの?
ミニスカートはとてもムリよ　若い子には負けるわ
私がオバさんになっても　ドライブしてくれる?
オープンカーの屋根はずして　かっこ良く走ってよ

私がオバさんになったら　あなたはオジさんよ
かっこいいことばかりいっても　お腹が出てくるのよ
私がオバさんになっても　本当に変わらない?
とても心配だわ　あなたが　若い子が好きだから

Fall passes, and Winter comes upon us, the time passes so quickly
For Summer break, you and I would go to Saipan Island, just the two of us
Even now my skin is still dark from that suntan, what happy memories
I want us to go to swimming at Saipan Island again next year, too
 
You're such a kind person, you draw me closer in an embrace
I wish we could remain like this always, I thought as you kissed me
 
Even when I become an old woman, will you still take me swimming?
I definitely won't be able to wear a flashy swimsuit, I'd lose to the young girls
Even when I become an old woman, will things really not change between us?
It really worries me, because you like young girls
 
Although you say that talking like that is foolish
You're the one that said that the peak of womanhood is nineteen
 
But you looked at me with that air of innocence
And told me that was a joke, as you kissed me
 
Even when I become an old woman, will you still take me out to disco?
I definitely won't be able to wear a miniskirt, I'd lose to the young girls
Even when I become an old woman, will you still take me for a drive?
Let's put the roof of the convertible down, and go for a cool drive
 
When I become an old woman, then you'll be an old man
Even as you say all cool things, your stomach will stick out
Even when I become an old woman, will things really not change between us?
It really worries me, because you like young girls
