[Verse 1: Marcus]
I was thinking about how you look
With the moon lightin' up your eyes
You're in my head and my heart and I know it's right
I got your hand in my hand and I'm digging this thing
Digging this thing when you're looking like bling
Never let go, I'ma do what I know is right

[Pre-Chorus: Martinus]
And if could feel your lips tonight
I think I wanna do this every night

[Chorus: Marcus & Martinus]
You are my first kiss
Never knew it could feel like this
I think I'm in love
You are my first kiss
Never knew it could feel like this
I think I'm in love
You are my first, first, first kiss
Never knew it could feel, feel, feel like this

[Verse 2: Marcus]
I don't know if you know
When my friends may have said I'm a fool for you
And I'm feeling that fizz so hard like I always do
I know it's late, but I must say I'm digging this thing
Digging this thing when you're looking like bling
Never let go, I'ma do what I know is right
[Pre-Chorus: Martinus]
And if could feel your lips tonight
I think I wanna do this every night

[Chorus: Marcus & Martinus]
You are my first kiss
Never knew it could feel like this
I think I'm in love
You are my first kiss
Never knew it could feel like this
I think I'm in love
You are my first, first, first kiss
Never knew it could feel, feel, feel like this

[Bridge: Martinus]
Been dreaming of you for so long
So I really had you to write you this song
And I've been known to put my worst right out
But you make me go silent now
What can I say?

[Chorus: Marcus & Martinus]
You are my first (you are my first) kiss
Never knew it could feel like this
I think I'm in love
You are my first (first) kiss (kiss)
Never knew it could feel like this (feel like this)
I think I'm in love
You are my first, first, first kiss
Never knew it could feel, feel, feel like this
You are my first (you are my first), first, first k​iss
Never knew it could feel, feel, feel like this
