She goes as far as possible

You sit back on your knees and look up at her with pleading eyes. She laughs and says, "You did good, now clean my pussy." You obey, and she shoves your face into her crotch. You try to avoid her smell, but you can't help yourself. You lick and suck her pussy lips as she rubs her clit. She moans loudly and you feel her legs squeeze around your head and doesn't let you breath. You keep going, hoping she'll cum soon. Her moaning gets louder and louder, and you wonder if anyone else heard her. She finally screams out in pleasure and you know that she came, but you're still stuck there, unable to breathe. She lets go of your head and you take a deep breath, then another, then another.
