Perfect size to eat it
You find yourself fixated on that ass, perfectly sized and impossibly round, demanding every bit of your attention the moment your eyes land on it.
You feel something primal stir low in your gut, the kind of want that bypasses thought entirely and goes straight to your hands, your mouth, your instincts.
You could spend hours there, tasting and gripping, learning every curve with your lips until the whole world narrows down to exactly this — nothing before it, nothing after.
