Tom Allison - Dental assistant on top

Graham sprawled on her bare backside, working his hips quickly, groaning with pleasure as he rammed his mammoth dick deeper and deeper into her well lubed bowels. Soon Karen was humping rapidly to meet his strokes, overwhelmed with the pleasure of sodomy, gasping and whimpering as she fucked her tender little asshole onto the satisfying stiffness of his big, probing prick.

It so happened that she did enjoy getting her butt hole fucked a great deal. In this case, however, she knew she would have acted like she enjoyed anything he wanted to do to her. Mr. Graham was a very handsome stud at age fifty, but he also happened to be the president of the company, the most important person she'd met from Cedar Manufacturing so far. If they were ever going to become the corporate dental agency, he was the one most likely to give Hank the title!

"Harder!" Karen pleaded, holding her ass checks spread open. "Unnngggh! Oh, it's so horny, Mr. Graham! My little asshole's so hot and juicy! Fuck it deep, Mr. Graham! Ungh! My asshole loves your big dick!"

Graham was now butt fucking the naked dental assistant good and hard, panting on her shoulder, furiously stabbing his huge fuck organ in and out of her bowels. Karen humped frantically to meet his rhythm, tirelessly thrusting her itchy asshole onto the root of his dick. Soon they were butt fucking in rhythmic unison, Karen squealing as she felt the giant prong growing bigger and bigger in her bowels.

"Gonna cum, Mr. Graham!" she panted suddenly. "Ungh! Oh, shit! My asshole's horny! Fuck my butt harder, Mr. Graham! Unnngggh! Cumming now, my asshole's cuminmiiinnnggg!"

Her tender, cock-stuffed asshole erupted in a series of uncontrollable spasms, milking and contracting around his hammering cock length, sucking every inch of his pisser. The horny company president kept fucking as hard as he could, guiding her through her orgasm. Then he collapsed on top of her, spearing his big prick to the hilt in her ass guts.

The sappy prick juice started spewing out, blasting up Karen's asshole, deluging her sensitive skit channel with a spouting load of cock cream. Karen shuddered as she felt the milky white jism squirting into her ass, soothing the sore, itchy walls with his jism.

"Oh, Mr. Graham!" Shamelessly, she kept wiggling and humping beneath him, flexing her shitting muscles, helping him squirt out every drop.

"I think," Graham said, as he pulled out of her aching asshole, "that you and your employer should start thinking of your company as the official service of Cedar Manufacturing from now on!"

"Oh, Mr. Graham!"

"And I must say, I hope you get a raise out of this," Graham sighed. "A big raise, too! You must be the most loyal, dedicated assistant any dentist ever had!"

"Jeez, just look at all these people!" Hank sprawled in the swivel chair behind his desk, staring in happy wonder at the appointment book. He was fully booked for the next four weeks. "Tomorrow, we've got four teeth cleanings, an undetermined pain in the lower jaw, an undetermined pain while chewing, an X-ray, a gum job…"

Hank whistled under his breath.

"It just goes to show you, perseverance pays off!" Karen said happily. She was standing beside him.

"This isn't perseverance! I mean, all those guys from Cedar Manufacturing! It's just incredible!" Hank shook his head. "I show up forty minutes late to meet that personnel guy, and now he refers everyone in the company to me. That's the kind of plum that any private dentist or doctor would practically kill to get! And it just dropped right into my lap!"

As long as you just keep thinking that, Karen thought. She squirmed nervously as she stood beside him, and prayed that he never found out the truth.

She was, by now, utterly in love with Hank, even though she was too horny to stop fucking and sucking other men. The only danger now was that he might one day learn what she'd done to make the agency so successful.

What, in fact, she was still doing, though now only with one executive. This was Mr. Graham, who, as president, still had the clout to have sole control over the dental contract, while still demanding in return that his big cock be sucked on a regular basis. Karen didn't mind doing this for him. He had a nice big meaty prick, and she was happy to take into her pussy, mouth or asshole at any time.

The only danger was being caught by Hank.

"Well, the least I can do is give you a big raise now, Karen," Hank smiled. "I mean, name your figure, okay? Two thousand a month? Three? More?"

"Hank… never mind that now," Karen said impulsively. Then she blurted it out: "I'm really horny, honey. Can I suck your cock for you?"

"What!"

"I said I'm really super horny, Hank! Please, I don't even know why, myself. I just want to suck your big prick again, Hank! Please?"

"Well, shit…"

Hank pushed his chair back from the desk, giving her a funny look as he spread his legs open. Her sudden, uncontrollable hunger for cock-sucking obviously struck him as pretty strange.

Karen didn't care. She dropped to her knees before him, almost trembling as she yanked open his pants and tugged them down to his ankles. Out bobbed his big prick, the long, meaty pisser she loved sucking and fucking most of all. Karen wrapped her fingers around his cock and started jacking hard and fast, her hand a blur as it pumped up and down his cock meat. "Shit, when you get horny, you really get horny fast!" Hank sighed.

Karen stuffed his by now stiff fucker in her mouth and started sucking immediately, clasping her lips around the cock shaft, shutting her eyes and sucking cock as hard as she could. It was just as well that Hank didn't know why she wanted to suck cock so badly.

It was because she was in love with him, and was afraid he'd catch her with Mr. Graham one day, and was afraid that this – or any day – might be her last chance to shove her lover's big prick between her lips.

"Do you like it?" Graham was panting. "Hmmm? Do you like it when I fuck your little asshole, Karen? Do you?"

"Harder!" Karen gasped. "Ohhh, yes, Mr. Graham! Unnngggh! My asshole just loves your big boner, Mr. Graham! Oh, hard, fuck it really hard!"

She was naked again, sprawled on her belly again, again holding her ass cheeks spread open as the company president shoved in his prick. The handsome, fifty-year-old Mr. Graham also loved her cock-sucking abilities, but fucking his cock up her ass seemed to be his favorite sex act of all.

His cock was fucking in deep now, plowing into her lube-slickened asshole, cleaving into the tender, spasming depths of her guts. Karen wiggled and humped eagerly beneath him, shuddering as the fuck heat built in her pussy and asshole at once. Soon the giant fuck organ was buried to the balls in her asshole, the root stuffed in her wet, itchy little shitter.

"Fuck my asshole, Mr. Graham! Utah unh unh, I'm so fucking horny! Fuck my little asshole!"

Graham started ass-fucking the naked dental assistant hard and fast, panting on her shoulder, drilling his enormous pisser in and out of her ass guts. Karen let go of her blushing ass checks, no longer needing to hold them open now that he had his cock impaled in her shifter. Instead, she thrust her hands under her belly and feverishly started finger fucking, jacking off her hairy pussy, fucking her hot, tender asshole onto the satisfying stiffness of his big pisser.

"Fuck my asshole, fuck my horny little asshole!" she pleaded. "Make it cum, Mr. Graham! Oh, fuck, you're making me cum!" Graham grunted on her shoulder, now hammering his big prick up her asshole as hard as he could. Karen grimaced, finger fucking in a frenzy, rolling her clit under her finger. Her face contorted with obscene pleasure as she felt the cum mounting deep inside her guts.
