18

All the guys gas me up on the swim team
 All her friends, they don't know that I'm 16
 I'm pretty psyched she's over every night
 I'm sorry if it ever pissed you off
 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
 Well she's 18, 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
 She's out of class for the week on vacation
 I'm tryna take anatomy in her basement
 I'm stuck in math, she's drawing up a bath
 And sending videos to my phone
 And I kinda like
 Staying up 'til morning under candlelight
 And swimming with you naked
 So I blow off my friends just to see you again
 I wonder if your brother's catchin' on
 Well, she's 18, 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 18, 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 comin' home
 I hope she doesn't leave me here alone
 She is 18
 She is 18
 Ah-ah-ah-ah
