Eat that ass out like a good boy

You obey, spreading her ass and working your tongue around her crack. At first, you're apprehensive, but soon you get into the task, pushing you tongue in and out of her pucker, licking her taint, and occasionally sucking on her balls from behind. You're driving her crazy, and she jerks herself off until she cums against the wall of the shower. She is only a moment recovering, then she whirls around to face you. "I need you," she says fiercely. "Either up against the wall, or on the shower seat, I don't care, I just need to be inside you!"
