Have her bend over the desk.

"Oooh," the nurse squeals, shivering in delight at your suggestion. Instantly she flips over, spreading her stocking-and-garter clad legs, her white high heels causing her hips to be thrust back, her perfect, heart-shaped ass and very, very wet cunt raised towards you. She grips the far end of the desk with her pink-nailed fingers, bracing herself, and rubs her huge tits and rock-hard nipples against the dark, fine wood.

You undress--at least enough--and take hold of her hips, guiding yourself into her. She's extremely wet and your cock slides in easily, spreading her tight, hot cunt. She pushes back at you, buyring you in herself to the hilt, and gasps in pleasure. You pull back, then push forward again, burying yourself once more, and again she shivers in pleasure, her cunt fluttering around your rod. Soon you have established a good rhythm, driving yourself in and out of the blonde, bug-titted nurse before you.

"Yeah, fuck it. Fuck my cunt," she rocks back at you, her enormous breasts rolling back and forth on the desk, and looks over her shoulder. "Fuck it nice and hard. Harder, yeah. Harder. Harder. Fuck me, fuck me, fuck me, fuck me..." she starts pushing back at you faster and faster as, goaded on, you start fucking her harder and harder. Soon the big desk is moving with each thrust, and her moans and cries are getting louder.

"Fuck me, fuck me good, oh yes, oh, so good, so fucking good, yes, fuck me, harder, harder, yes, that's it, oh God, oh God OH GOD FUCK ME FUCK ME YES FUCK OHHH--" she throws her head back, her cunt clamping down on you as she cums, her head shaking, her blonde hair flying, her white nurse's cap somehow staying on. She lowers her head to the desk as you continue.

"Oh yes, oh yes, fuck me, oh, fuck me, so good, oh yes, fuck that cunt, fuck it nice and hard, oh God..." she arches up and squeezes one of her breasts, hard, then twists the nipple. "Grab my hair," she says. "grab my hair and pull it hard, pull it and fuck me hard. Make me cum again, oh yes..."

Of course you oblige, and she starts pushing back at you harder than ever, faster and faster, forcing you to up the speed and tempo, and now the big desk is rocking. She cums again, and you see her eyes roll up into her head this time as her cunt squeezes your cock.

All of this is nearly too much, and she seems to sense it. "Cum for me," she pleads, rolling her hips now. "Come on, do it, come on, yes, yes, yes..." it seems she's working herself up to peak with you when suddenly there's a noise at the door.

"Oh fuck--the supervisor! Quick--"

Before she can finish her sentance, the door flies open and a tall woman in a woman's business suit storms in. "Nurse Watkins!" The blonde recoils from the shout as the supervisor looks at the scene in disbelief. "In my office? Again?" You notice a certain flush in her cheeks, and she's definitely letting her gaze linger on Nurse Watkins--especially her breasts--much longer than strictly necessary.
