Tom Allison - Dental assistant on top

Then he started butt fucking his big sister fast and hard, working his meat organ in and out of her, ramming his giant prick a little farther up her ravished shit channel with every skewering stroke.

"Unnggh! Oh, Jimmy!" Karen stopped holding her ass cheeks spread open. Eagerly she thrust her hands under her belly, beginning to finger fuck her wet, hairy pussy as Jimmy reamed out her bowels.

"Make me cum, Jimmy! Unh unh unh, fuck my asshole, fuck my horny little asshole! My butt needs hard fucking, Jimmy! Oh, please, my asshole needs a good cum!"

Jimmy fucked harder and harder, panting on her shoulder, his giant prick nursed to total stiffness by the constant, rubbery grip of her shaft milking shit sphincter. Soon his prick was as hard as steel inside her, signaling that he would soon be dumping the load of goo out of his balls. Jimmy fucked harder than ever, completely reaming out her itchy little asshole with every stroke of his meat.

"Gonna cum now, Jimmy! Umigggh! Fuck my asshole, fuck my horny little asshole! Unnggh! Cumming now! Cuummiinnnggg!"

Violently her horny little asshole burst into orgasm, spasming around her brother's pounding boner, milking every inch of his huge, thrusting prick. Jimmy fucked his big sister harder than ever, guiding her through the violence of her cum. Finally he collapsed on top of her, burying his balls in her backside, gasping as the pent-up load of cock juice started to spew out of his dick.

Rhythmically the sticky white load squirted up his sister's asshole, basting her tender anal walls with the flowing warmth of his cum cream.

"Oh, Jimmy," Karen panted dazedly. Eagerly she kept wriggling and humping beneath him, flexing her shitting muscles, making her tight little asshole suck every drop of cum out of his prick.

"Gosh, Jimmy, I just don't know what to do," Karen was complaining a few minutes later, lying bare ass with her brother. "We hardly have any money left at all. I just gotta get a job!"

Jimmy turned toward his sister and gave her a gentle, brotherly kiss on the cheek. Then he twisted sideways on the bed, opening the nightstand drawer and pulling out a wrinkled business card. He flipped it on her belly.

"What's this?" Karen held up the card, squinting at it. "Janet Chase, General Dentistry," she said, reading the printing aloud. "What's this about?"

"It's this lead I dug up for you," Jimmy said proudly. "I figured I wouldn't need it any more once you started working for that Wallace guy. Now I'm just glad I saved the card."

"Who's Janet Chase?"

"Chick I met in a cafeteria. Round thirty-eight, but super, super foxy-looking, blonde, long legs, the works. Just wish I'd gotten a piece of her," Jimmy sighed. "Anyhow, it turned out she was a dentist. I got to talking about you, and she asked all these questions about Rickman-Hymer, what you look like and so on, and then she said she might be interested in hiring you. So how's that for a lead!"

"Oh, Jimmy! Golly, you must be the most wonderful little brother in the whole, wide world!"

Karen twisted toward him, her huge jugs quivering as she gave him a long, grateful kiss. The embrace, however, swiftly degenerated into a lot of fondling and groping.

When Karen felt her kid brother's getting stiff again, she couldn't resist sliding her hand down to jack on it. Less than a minute later, Jimmy was moaning and gasping in ecstasy as his horny big sister fucked her mouth on his prick, feverishly slurping and jacking on the pulsing hardness of his cock.

His prick was all sticky from fucking her asshole, but Karen didn't care. A lead for a new job! It was so wonderful! The best way to repay Jimmy was to suck his dick so he couldn't see straight!

Sometimes she thought she had the most wonderful little brother in the whole, wide world!

"Gosh, Ms. Chase, you really don't have to do this for me," Karen was saying late the next afternoon. "I mean, it was nice enough to hire me right on the spot like you did. I sure don't think you have to give me a massage and everything too!"

"Nonsense," Janet Chase cooed. She was, as Jimmy had described her, a slim, pretty blonde in her late thirties. "You've been such an ordeal with that horrible Max Wallace. Now just relax and let me help you feel better."

Karen just sighed. She was lying on her stomach on the big couch in the female dentist's private office, naked from the waist up, her huge, spongy tits pressed on the cushions as Janet massaged her back.

Everything today had happened like a dream come true! Janet Chase had only asked her a few questions before hiring her on the spot. It was, Karen supposed, a little strange that she hadn't helped out with any patients yet, Janet had insisted on attending to the three clients that day all by herself.

It was also a little strange that Janet had stared so intently at her body, or that Janet was now so insistent about giving her a back rub now. But, Karen knew, she didn't really have anything to complain about. A new job so soon! Gosh, her luck sure had taken a turn for the better!

"Now why don't you turn over, dear," Janet cooed. "Let's take care of your front too."

"You really don't need to do this for me, Ms. Chase. My muscles don't feel sore at all."

"Nonsense, Karen! You're much too hard on yourself. Now roll over like a good girl."

The female dentist's words trailed off as Karen did as she was told, rolling onto her back on the couch. Her enormous, creamy-white tits jiggled heavily with the movement, continuing to bob and undulate slightly as she looked up at her new boss. Her nipples were like two huge pink eyes meeting Janet's gaze as the dentist stared intently at her huge tits.

"You… you certainly do have an extremely large bosom, Karen," Janet said, in a funny voice. "Honestly, I don't think I've ever seen such a slender girl with such big tits. I suppose… they must get sore occasionally, don't they?"

"Not really," Karen replied, wondering what the dentist meant.

"Oh, I'm sure they must."

Janet lowered her hands, filling her spread fingers with the spongy enormity of Karen's huge baby feeders. Karen finally began to suspect what was going on as the dentist kneaded and squeezed her giant tits, rolling the soft tit-flesh under her palms, touching the nipples until the dugs were crinkled and stiff.

"Is this making your big bosoms feel better, Karen?"

Karen just looked up at her, suppressing the urge to frown. Another tit freak!

She never had a chance to say anything. Janet suddenly seemed to lose control of herself. With a wanton little moan, the dentist plunged downward. She cupped one huge suckler in both hands, gluing her open mouth to the goose bumped tit cap.

"Ms. Chase!"

"Oh, let me suck them, please let me suck them!" the lesbian dentist gasped. "Oh, they're so big and juicy, oh, please!"

Janet's words faded as she again applied her lips to Karen's huge jug. The dentist's tit hunger was amazing. Janet slurped on Karen's huge mammary as hard as any man ever had, puckering her cheeks hungrily drawing the sensitive tit flesh deeply between her lips. In spite of herself, Karen felt her pussy getting wet. She sighed submissively, listening to the slurping, gurgling sounds of Janet's tit-sucking pleasure filling the office.

"Gosh, Ms. Chase, this is so awful!" she sighed. "All I wanted was a job, and now you're treating me like a sex object too! Golly, sometimes I wish my titties weren't so big at all!"

But the female dentist was much too busy slurping on Karen's huge tits to answer. Janet switched breasts, leaving the first nipple stiff and glistening with saliva, quickly engulfing its twin. Karen shuddered as the fuck heat built rapidly under her panties. She could hardly believe that the touch of another woman could make her pussy feel so wet and hot.
