Oohh,
  You always told me
  If I ever want to leave
  If I find the better girl
  Someone who lets me breathe
  That you wouldn't stand in my way
  Oohh girl I never meant to break your heart
    I promise you
  I didn't know, oh no
  She was your sister, sister
  What could I do
  She is so dope, oh yeah
  I couldn't resist her
  Your little sister
    And who would've thought
  That she's really that young
  Unlike you
  Kisses good with the tongue
  Oh please don't stand in the way
  I guess it really doesn't matter
  If I break your heart...
    I promise you
  I didn't know, oh no
  She was your sister, sister
  What could I do
  She is so dope, oh yeah
  I couldn't resist her
  Your little sister
    How, ooh,
  Oohh, how could I know
  How could he know
  How could he know
  How
  I'd really, really didn't know
    I promise you
  I didn't know, oh no
  She was your sister, sister
  What could I do
  She is so dope, oh yeah
  I couldn't resist her
  Your little sister
    I promise you
  I didn't know, oh no
  She was your sister, sister
  What could I do
  She is so dope, oh yeah
  I couldn't resist her
  Your little sister
