[Verse 1]
All the guys gas me up on the swim team
All her friends, they don't know that I'm sixteen
I'm pretty psyched, she's over every night
I'm sorry if it ever pissed you off

[Pre-Chorus]
Well, she doesn't mind
Driving home from campus for a younger guy
I'm lying to my parents
Said I'm out with my friends, sleeping over again
But really it's just her and I alone

[Chorus]
Well, she's eighteen and she does what she likes
Making out with strangers when she's bored with her life
And she takes me to a whole 'nother high
I wonder when she'll stop coming home
I hope she doesn't leave me here alone

[Verse 2]
She's out of class for the week on vacation
I'm trying to take anatomy in her basement
I'm stuck in math, she's drawing up a bath
And sending videos to my phone
[Pre-Chorus]
And I kinda like staying up 'til morning under candle light
And swimming with you naked
So I blow off my friends just to see you again
I wonder if your brother's catching on

[Chorus]
Well, she's eighteen and she does what she likes
Making out with strangers when she's bored with her life
And she takes me to a whole 'nother high
I wonder when she'll stop coming home
She's eighteen and she does what she likes
Making out with strangers when she's bored with her life
And she takes me to a whole 'nother high
I wonder when she'll stop coming home
I hope she doesn't leave me here alone

[Outro]
She's eighteen
She's eighteen
