カラオケなどでの[延長](https://eikaiwa.dmm.com/uknow/questions/38640/)という習慣は英語圏にはない、あくまでも日本独特のサービスであるため、定番の自然な表現というものよりは直訳に近い訳でしか言い表せないことと思いますが、まずは〝延長” ＝ ”extension”（名詞）、“extended time”（[時間](https://eikaiwa.dmm.com/uknow/questions/45991/)を延長する） という表現が思い浮かびます。
Can we have extension, please? （時間延長でお願いします。）
We'd like to extend our time. （時間延長してください。）
We would like to ask for extended time. （時間は延長でお願いします。）
こんな感じになるでしょうかね～！！
少しでも参考になればと思います。
We are having such fun...let's extend the session for another hour!
We can sometimes find that ..." time flies when we are enjoying ourselves".
Say in a karaoke bar or playing games like paint bal etc...And "before we know it"
We have run out of "the allotted time". Not a problem usually ;-))
Simply ask to "extend the session!"
私達は時に" time flies when we are enjoying ourselves"（楽しい時間は飛ぶように過ぎていく）と実感することがあります。
例えばカラオケ店の中だったり、ペイントボールのようなゲームをしたりしていると、"before we know it"（気づかないうちに）"the allotted time"（与えられた時間）が終わってしまっています。たいていの場合は問題はないですが。
単に "extend the session!"（延長する）ようにお願いしましょう！

You may politely ask the organizer by starting with the adverb 'please' to give the karaoke more time'
So, you may say:
Please give the Karaoke more time.
or
you may politely ask the organizer as follows:
Will you please extend the karaoke time?
or
Please let the karaoke last longer.
To last longer actually means to go beyond the time something was supposed to end.
please' という副詞を使うことによって丁寧に主催者にカラオケの延長をお願いできます。
このように使えます:
（英文）
Please give the Karaoke more time.
or

or
Please let the karaoke last longer.
To last longer actually means to go beyond the time something was supposed to end.

If you would like to extend your time in a place and want to ask someone to help you, you can say something like "I would like to extend our time please." or "Can I please extend our time please?". This is an easy way to ask someone to help you extend the time on something, for example karaoke.

「延長」という言葉を英語で表すと、「extension」と「time extension」または「extended time」という言葉を使っても良いと考えました。延長を頼むと、「Please give me a time extension.」と言っても良いです。質問で頼みたい場合、「Can I please have an extension?」という質問を使っても良いです。

延長 = extension
カラオケでは、延長するのは"time" (時間）です。
簡単でいうと、"Please extend our time" = 「延長お願いします」です。
"We'd like to extend our time." = 「延長したいのですが」（主語を加えましたが。）
カラオケ以外の例文：
May we please have an extension of the deadline?
Could you please extend the deadline?
両方の意味は「締め切りを延長いただけますか」。ただし、１番目のextensionは名詞で、２番目のextendは動詞です。
"May we have an extension?" = 「延長お願いできますか」もしくは「延長いただけますか」
Me and my friends are having so much fun here! Could we extend for another hour please?
Examples:
Could we extend for another hour please?
If it's possible could we extend for another hour?
If there are any slots available could we extend our booking?
Can we extend our booking please? We are having such a good time, we are not ready to go yet.
Here are two examples that we can ask when we want to extend our time at a place or when doing something for a rented amount of time. Notice that we can either use the noun version, "extension," or we can use the verb version, "extend," to have the same effect in these phrases.
When you want to ask to extend the time at a place, then you may use the following expressions:
-more time
-time extension
You may use the above phrases in the following ways:
-Would it be possible to have more time for karaoke?
-I would like a bit of time extension for my time here. Would that be possible?
延長はextendとextensionです。
お願いします - please, can I, may I?
