Don't say it's a lie

little girl, I knock on your back door 
x2 
First I kiss you once 
then I kiss you once more 

little girl open your little mouth wide 
x2 
you know iI love you girl 
and don't you say it's a lie 

little girl now I'm lifting your latch 
x2 
First I kiss your front now 
I'm gonna kiss your back
