Back in the day when you were young (it was fun)
Little girl, didn't think you were the one (now here I come)
Your sexy walk, your sexy talk (that's whats up)
Little girl, you're clearly not the same kid from the block

I ain't that little girl no more
Not no more, that's for sure
Boy get your ass out on the floor
Let's explore, let's explore

You know I like the way you moving (moving)
Girl you're all grown up and now your ready to let it go
Wanna be a big girl, got to prove it (prove it)
With a body like that you got a grown man ready to blow

Back in the day when I was young (kinda dumb)

Gonna get you wet, gonna make you sweat (girl I bet)
Gonna give you something you ain't ever gonna forget

You ain't no little girl no more (nope)

Wanna work it like a big girl let's explore
Now drop it to the floor, lets get raw

You know I like the way you moving (moving)
Girl you're all grown up and now your ready to let it go
Wanna be a big girl, got to prove it (prove it)
With a body like that you got a grown man ready to blow

You know I like the way you moving (moving)
Girl you're all grown up and now your ready to let it go
Wanna be a big girl, got to prove it (prove it)
With a body like that you got a grown man ready to blow

Baby good things come to those who wait
Come and take it mama before it's too late
