When youre sound asleep then become awoken by your dude but you can't open your eyes bc he is standing squatting over your face with his ass cheeks ful spread whilst your eyes are total Tea bagged by his hanging balls causing you to be disoriented and temporarily blinded by warm scrotum causing not such a lovely awakening!
