Shamelessly Karen started finger fucking, darting her fingers in and out, rubbing her fat little clitty while her kid brother reamed out her bowels. The combination of sensations in her pussy and shit hole soon got the better of her. Within a minute, Karen was humping as hard as she could, groaning and whimpering as she fucked her needy, horny whole onto her brother's pounding prick.
"Fuck my asshole, Jimmy!" she gasped. "My little asshole's so fucking horny! Gonna cum now! Fuck my asshole, fuck my horny little asshole! I'm cumming, Jimmy! Cumming, eiiuummmiinnngggg!" Karen humped in a delirium of orgasmic passion, torridly finger-whipping her pussy, tirelessly thrusting her stretched, squishy asshole onto his big, skewering prick. Jimmy butt fucked his naked sister as hard as he could, guiding her through the writhing violence of orgasm.
Suddenly he came down hard, moaning as he rammed his huge prick in to the hilt. A second later a tremendous load of prick juice was spouting out of his boner, making the big prick twitch and quiver up her asshole as spurt after spurt of cum sap streamed out of his big cock.
"Keep cumming, Jimmy! Keep shooting your cum up my butt!"
Her brother's orgasm lasted nearly a minute. When he finally pulled his huge prick out of her asshole, Karen's shit-sphincter felt swollen and bubbly with the welling-up load of jizz.
Jimmy flopped onto his back, gazing dazedly up at the ceiling. As horny as she still felt, it wasn't long before Karen's mind returned to her other problems.
"Jimmy, do you know how much money we have left?" she murmured.
"Neither do I, but it's not much. I gotta get a job!"
"Very pretty girl," the man was saying. He sat behind his desk with his fingers interlaced, nodding his head sagely. "Yes, that's what you are. A very, very pretty girl!"
"Th-thank you," Karen murmured. "Please take it as a compliment."
"I do."
"A very pretty girl."
The man's name was Max Wallace. He was about thirty-five, Karen supposed, short and sturdily built, with a knowing smile and thinning black hair. He didn't look like a big businessman, but Karen supposed that he was.
Executive Dental, which Max Wallace owned, took up half of one city block. She was here in his private office for a job interview, her first job interview ever as a dental assistant. Karen faced Mr. Wallace in her best pleated skirt and a formal, frilly white blouse. Her newly issued diploma was folded safely in her purse, which she held in her lap.
Karen felt very nervous, and the impressiveness of Executive Dental had done nothing to put her at ease. As Mr. Wallace had smugly volunteered, his business was the largest of its kind in the state. It was, he freely admitted, a high-volume, turnstile type of operation, that made its profits by offering low prices to as many customers as possible.
On her way in, walking to the stairs, Karen had counted at least a dozen dental booths on the first floor alone, with young dentists and white uniformed dental assistants scurrying busily about left and right. The second floor, where Mr. Wallace had his office and where she was sitting now, seemed to be a bit different. The dental booths weren't really booths; they were separate, private offices. Max Wallace had already explained that the clients serviced on the second floor were more select, as he put it. They were also charged more money.
This didn't explain why the two dental assistants she'd seen on the second floor were so conspicuously younger and prettier than the one's she'd seen downstairs.
"What are your salary requirements?" Mr. Wallace asked.
"Well, I… I'm just starting out," Karen flushed. "I mean, whatever… well, whatever your starting salary is here, I'm sure it would be fine…"
"How does twenty-five hundred a month sound?"
"What!" Karen's eyes widened.
"This is to start, of course."
"Well, that…" Karen's mind reeled. "Well, that… that's extremely generous, Mr. Wallace!"
"When can you start working?"
"Well, I could… right now, I guess! But I… I'm sure you need time to check my references from Rickman-Hymer, don't you?" Karen opened her purse. "I did bring my diploma along."
Wallace waved his hand. "Not necessary."
"You… you don't need to see my diploma?"
"Not necessary. You're a trustworthy girl. I can tell, just looking at you. A trustworthy, pretty young girl." Suddenly Max Wallace stood up. "We need to have you fitted."
"Excuse me?"
"The fitting room! Follow me! We need to find a uniform for you! Come, come!"
He strode out of the office, giving her no choice but to follow. Together they strode down the second-floor corridor, at one point nearly bumping into a blonde dental assistant who was just leaving one of the private upstairs booths.
The woman was wiping something from the corner of her mouth. She noticed Karen staring, and gave Karen a quick, dirty look before disappearing into another one of the other rooms. Karen shook her head and hurried after Mr. Wallace.
The woman hadn't looked like a dental assistant. She'd looked like an aging showgirl, with an incredibly voluptuous body under her white dental assistant's smock.
"That was Angela," Wallace said. "She's one of my very best girls, but I'm afraid she's not very friendly to newcomers."
"I see."
"Here we are."
Wallace produced a string of keys from his pocket, unlocking one door, opening it to reveal a small, brightly lit wardrobe room. A rack full of uniforms hung on the opposite wall.
"Go ahead and get undressed and see which one fits you," Wallace said. "I'll check on you in a minute."
And then he left her, giving her just enough time to enter the wardrobe room before shutting the door behind her. Karen just stood the for a minute, trying to get her bearings. Twenty-five hundred a month! And he'd already hired her! It was too much to believe.
Well, she'd just better be sure to stay in his good graces! Karen put down her purse and swiftly stripped off her cloths, folding her blouse and skirt neatly over a chair. She automatically unhooked and removed her bra letting her enormous, creamy-white tits tumble out of confinement. Just as she finished draping it over the chair, too, the door suddenly swung open again.
It was Mr. Wallace.
"Awwk!" Karen squealed.
She spun toward him, her checks flushing a hot pink as she struggled to fold her arms over her jiggling tits. But her boobs were much too large to be concealed this way. Except for her panties, she was completely naked. "Mr. Wallace!"
"Oh, excuse me. I thought you'd be finished by now."
Wallace shut the door spin, with him inside it. Then he faced her, staring straight at her body.
"You know, your breasts are extremely large," he said.
"Well, I… I know that!" Karen squealed. She was still trying to cover her huge tits with her arms.
"They're so large we might not have a uniform to fit you. Hmmm." Wallace stepped up, still looking very businesslike. "Please remove your arms."
"What!"
"I said, please stop trying to conceal your breasts with your arms. I need to see them."
Wallace looked slightly irritated. Karen hesitated, then embarrassedly lowered her arms to her sides, letting her new boss look at her huge milkers. Wallace stared, admiring the giant, round, creamy-white tits, with the wide, pink nipple caps in their centers.
Karen gasped as he raised his hands, filling his fingers with the spongy enormity of her tits.
"Mr. Wallace!"
"I'm trying to determine how large they are." Wallace stepped very close, gently fondling and kneading her huge sucklers. In spite of herself, Karen soon felt her pussy getting wet and hot.
"I think I may have one uniform that will fit. You might have to do some contortions to get into it, though," Wallace said. He kept fondling her tits. "Your nipples are quite sensitive, aren't they?"
