"Unngggh! Oh, shit, Jimmy! That feels so good!" Karen gasped. "Unh! Lube up my little asshole, little brother! Oh, fuck, oh, shit, my little asshole wants your big dick!"
It was now about seven in the evening, only a few hours since Karen had stomped out of Executive Dental and bade farewell to her first ever job as a dental assistant. As usual, she'd decided that the best way to relieve her tensions was with plenty of sucking and fucking.
And her favorite partner these days was her own little brother. Jimmy had already fucked her pussy once, but he hadn't dumped his cum load inside her yet, and Karen's tingling, itching asshole had told her where she wanted to feel his stiff pisser pounding next.
Now she was hunched up on her knees on the bed, her shoulders pressed to the sheets. Shamelessly she held her round fanny cheeks spread wide open, opening up her pink, puckered asshole so her brother could lube it up. Jimmy was kneeling beside her, his giant fuck organ already well anointed with Vaseline. He dipped his fingers into the jar and smeared more of the jelly on his big sister's sensitive little shitter, until her rosy asshole ring was glistening with the lube.
"Fuck my asshole, Jimmy!" Karen cried. "Oh, I'm so horny! My asshole needs fucking bad!"
Jimmy mounted his horny big sister, aiming his swollen cock head at the rubbery ring of her asshole. Seconds later, Karen's expression contorted with pleasure as she felt her tender, sensitive shit-hole opening to admit his prick.
In and in the meaty rod pushed, cleaving relentlessly into her bowels. Karen shuddered with pleasure and started humping furiously, eagerly thrusting her aching, horny whole onto the satisfying stiffness of his dick.
"Feels so good, Jimmy! Unngggh! Oh, fuck, my little asshole needs fucking so bad! Shove it all the way in, Jimmy!"
Jimmy came down hard, moaning as he slammed his big dick to the hilt in the rubbery, shaft-sucking tightness of her bowels. For several seconds he lay motionless on top of her, letting her powerful asshole muscles suck and grip around his dick.
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!
