Put it in her cunt.

"Oh, yeahhh..." the nurse squirms, pushing back towards you as you slide yourself into the moist heat of her cunt, which seems to surround your cock like a tight sleeve custom-made to fit it. She quicks starts rocking back and forth, and soon the two of you are moving together in your own rhythm, one which escalates quickly in tempo and urgency.

"Give me that cock," she moans. "Fuck me nice and hard, fuck my cunt, fuck that cunt, fuck it, fuck me, fuck me hard, harder, harder, yes, fuck me fuck me fuckmefuckmefucke FUCK MEEE!" She arches her back and her pussy clamps down on you as she cums, tossing her hair, her nurse's cap somehow managing to stay on as her blonde hair flies about.

Your own climax is not far behind you can tell. Her huge tits bounce and sway beneath her as you pound into her cunt, and she pushes back eagerly at you, ready to take it all, demanding that you go faster, harder, faster still. Suddenly she arches again, thrusting those enormous breasts out in front of her, crying out as she screams again, her eyes rolling back in her head and her tunnel squeezing you like a vice. It's too much--you're about to explode.
