do you wanna fuck your sister, or do you wanna fuck someone who knows everything about you, knows your whole life from the moment you were born, as been with you ever step of the way and seen every mistake you've ever made, everything you've ever done wrong, and loves you anyway? do you want to stop being scared that they'll find out the truth, lean your mistakes and hate you for them, stop being afraid that it could all go up in smoke if they ever realize who you are underneath, because they already know, and they've always known? do you want them to understand every inch of your mind because they've seen it all laid bare, because they know everything about you and what you want, what you need, even when you don't know yourself, because they know everything there is about you, because they've been by your side, watching you your whole life? do you wanna fuck your sister, or do you just know that no one else can ever, truly, unconditionally love you the way she can?
