The strapon.

The supervisor gives a self-satisfied smile. "I thought so," she says in a cultured tone, as if to herself. With a single swift motion she undoes and tosses aside her business jacket. It lands on a coatrack across the roof, perfectly hooked. Strutting back around the desk, the supervisor undoes her skirt, lets it fall, and steps smoothly out of it, all without breaking stride. Next she unbuttons the her white shirt and throws that aside as well, though this lands in a heap atop her discarded skirt.

The body exposed by this quick strip-act would be impossible to describe without using the word "statuesque". Tone and fit but very well-curved, the supervisor is dressed in a black pushup-bra and back thong, as well as her seamed stocking and dark blue, low-rise heels.

Her smile is a smug cat's smile as she sees you taking in her form, and she sheds her panties and puts on the strapon harness with the ease of long practice. Like her bra and now thrown-aside panties it is completely black, and it makes a lovely contrast to Nuse Watkin's white stockings and uniform as the supervisor comes up behind the blonde nurse, laying a long-fingered hand on that rounded, full rear.

One of those long fingers comes down and traces its way up the folds of the blonde's shaved sex. Nurse Watkins jumps a little and gives a soft gasp of pleasure. Her eyes watching yours, the supervisor brings that finger up to her mouth and delicately licks at it.

"I see our volunteer has you nicely prepared for your punishment," she says, and smiles her wry smile at you once more.

Suddenly her tone is all business. "Nuse Watkins! You have been a very naughty girl. Say it."

"I--I've been a very naughty girl," the blonde stammers, her voice high and meek.

The supervisor caresses Nurse Watkin's ass once again. She's still looking at you as she speaks. "You're a naughty slut nurse who needs to be fucked. Say it."

"I--I..."

The supervisor brings her hand down in a sharp slap, and the nurse cries out, raising her body off the desk, her huge tits projecting out in front of her arched back. "Say it, bitch!" She points at you. "And you, start stroking. I want that sample before Nurse Watkin's punishment is complete, do I make myself totally and completely clear?"

Your head jerks in a nod and your hand starts working on your stiff cock, as if her tone set off some previously undiscovered reflex of obeyal. "Good boy," the supervisor croons, and turns her attention back to the nurse. "Say it, bitch."

The blonde hands her head again. "I--I'm a naughty slut nurse who needs to be fucked." You can see Nurse Watkin's stockinged legs spreading a bit further as she says this, and moisture from her cunt is starting to run down to her garters.

"And you will get fucked, you slut bitch," the supervisor growls. She grabs the blonde's hair again and hauls her over to the side of the desk, standing astride her own discarded clothing, and tosses Nuse Watkins down. "Grab the edge of the desk, slut, and keep your head down." Nurse watkins complies and the supervisor positions herself behind the blonde, then thrusts the stropon in, burying it to the hilt.

The nurse arches her head and cries out as if in pain, but she shoves her ass back at the supervisor, who immediately grabs the nurse's hips and starts hammering the black latex cock into the shaven cunt before her. She reaches out and grabs the blonde's flowing tresses, hauling her hair back and using it like a set of rains to pull the big-titted nurse into her thrusting.

From this angle you can see everything. Nurse watkin's cheeks are flushed with passion, her eyes half-closed, her wet, red lips parted and her tongue licking them ocassionally as she moans and gasps in pleasure. Her gigantic, round breasts, pink nipples erect, bounce and sway as her female supervisor fucks her, and her legs, with their white stockings, garters, and white high-heels are spread in acceptance. Her bubbled butt thrusts back as the strapon pounds into her.

Behind her, one hand on the blonde's hip and one hand in her mane, is her supervisor. Much taller, built like a pinup, her expression is fierce as she drives the false cock into her subordinate again and again and again. Her taut rear is tense, her dark-stockinged legs showing every trim muscle as she uses all her strength to punish the nurse with a powerful fucking. Her breasts project out before her, squeezed up and together by the pushup bra, and they bounce with each savage motion. Her hair is still back in its severe bun, and she's hissing a constant stream of **** at the blonde.

"Little slut bitch, little nurse whore, that's what you are. Take your punishment, you naughty little girl, you naughty little tramp, take it and love it. You love being fucked. Love being fucked in your little slut cunt, fucked by another woman in your little slut cunt, fucked by a big, fake dick in your little slut cunt. Naughty nurse, naughty little bitch of a nurse..."

She's working herself into a frenzy, fucking the nurse harder and harder, making Nurse Watkin's breasts bounce and shake and causing her moan more loudly in pleasure. The supervisor hauls back further on Nurse Watkin's hair, slamming into her so hard no that the desk is shaking, and Nurse Watkins's body stiffens, then shakes and she cries out, her eyes rolling back into her head as she cums and cums and cums.

The sight of this, and of her supervisor still fucking her unrelentingly, is too much for you, and you find yourself shooting forth your load into the bottle provided you, filling it quickly and seeing spots in your vision. The supervisor looks over as you do this, and you think you see her tense and her cheeks suddenly flush. She shivers and then stumbles back from the nurse, using her grip on the blonde's hair to toss her towards you. "Go pick up his sample, bitch, and take it down to the lab."

Her eyes turn to you as the Nurse, reeling and barely able to walk, collects the jar with shaking hands. "You," she says. "Pick up your payment at the front desk. We'll call if we want more. And not a word about this to anyone, understand?"

You find yourself nodding weakly, and follow the nurse out, barely able to walk yourself.

In no time at all, it seems, you're back on the silent, empty street, heading away from the Center and back towards your home. Your wallet is heavy with cash again, and what an amazing day. All in all, a very successful venture.
