Always do your best for me, because you're never quite good enough.
Your holes could be tighter.
Your arch could be deeper.
Your tits could be bigger.
You could be dumber, your moans could be hotter, you could listen faster, your worship could be stronger.
Do your best, and then a little better, because your best still isn't quite good enough. Be a better slur. Be a better cunt. Be a better girl.
