While Karen was out, Jack discovered that the phone lines had been repaired and attempted to call his wife. There was no answer, but he assumed that she and Jerry were checking the animals. He would try later.
When his sister returned with the groceries, she allowed Winston, her Great Dane, inside with her. She saw how Patti fussed over the big dog, and asked if she would mind drying him with a towel, and then feeding and combing him.
"How about using the spare room?" she suggested. "He can make quite a mess when he's excited." Patti agreed happily, for she hadn't liked thinking about poor old Winston out in all that wind and snow.
"And you," she said, turning to her brother, "can help me put these canned goods away in the back."
As Jack followed his sexy sister he studied her jiggling ass and realized that she wasn't wearing anything under her lightweight dress. Once in a while the light would hit the thin fabric just right and silhouette her shapely legs and fabulous tits, and Jack felt his cock thicken. Shit! What a time to get a hard-on! He could hardly wait for bedtime, when he'd be able to slip into Patti's room and let her drink his hot cum.
Right now he couldn't pull his eyes from Karen's plump, firm ass as it shivered and rolled with her steps. Staring at it made him recall how it had looked in the bathroom, bare and upturned, her full, pink asscheeks clenching and unclenching around her dainty little asshole as she slavered in her shaggy-fringed cunt.
His cock was soon straining mightily against his tight pants, and his mind raced with ways to get Patti alone within the next few minutes. His balls felt so full and heavy that, if he'd been alone, he would have whipped out his prick and beat it until the walls and floor were covered with his thick cum. His face felt hot and he sensed the blood pounding in his ears as he recalled his session with Patti.
Just a few paces in front of him, the woman who had caused his horny state was herself filled with incestuous lusts, and deliberately swayed her hips as she thought about her brother's peeping. Knowing Jack, he'd milked his prick dry while watching her lick her cunt. Damn, what a waste of cum! She felt hot cunt juice seeping between her plump pussylips and coating the insides of her inner thighs. She gave a little shiver even though the furnace kept her house quite warm. She'd purposely asked Jack to accompany her because the storeroom was at the far end of the house, well away from where Patti was busy with Winston.
So, if she didn't lose her nerve, her niece wouldn't be able to hear the groans and cries of her anticipated climax. It was sort of funny, Karen thought, for her to be the one to lose her head like this. When they were kids, she'd been the one to slap Jack down and, after his marriage, had teased him about his lust for little girls as a teenager. Beth thought it was all a joke, never realizing that Karen was talking about herself.
She'd watched her brother at the breakfast table. Even before he offered to help with the dishes, she'd seen him eyeing her big tits with more than brotherly interest, and knew that he'd go wild when he finally had those melons in his hands.
It would be fun to let him share in the seduction, even if she did most of the leading. No matter how it happened, Karen was determined to get her brother's cock inside her hungry cunt. She turned as they entered the storeroom.
"My God, Jack!" she cried, her eyes dropping. "What have you got in your pants?" She pretended to be shocked at first, then dubious.
"What'd you do?" she asked as he stammered. "Stuff some rolled up socks in your shorts?"
"No! No… I… hell, it just happened, I…"
"Nobody's that big, little brother," Karen said, shaking her head. "I knew some teenagers stuffed their shorts with socks to out-macho their friends, but it's not a trick I'd expect you to pull at your age, especially on your sister."
Jack's face was red and his mouth was hanging open. What could he say? Shit, his damn cock was still stiff, completely unconcerned by his embarrassment.
"I'll bet you're pretty small," Karen was saying. "Otherwise you wouldn't feel the need to exaggerate. I've read about guys like you, usually three or four inches who know they're inadequate…"
"Damnit, Karen, shut up!" Jack cried, stung into defending himself.
Karen laughed derisively, but inside she was seething with kinky desire. Teasing her older brother about the size of his cock was turning her on even more. "So I hit a nerve, eh? Not more than four inches, I bet!" She laughed. "Poor Beth…"
"That's not fair!" Jack said loudly, trying to reason with her. "You know I… I can't disprove it!"
"You can't because I'm right," she said smugly. "I dare you to prove me wrong!"
When he turned red and mumbled, she taunted, "Any excuse to hide your puny prick, eh? Don't worry, a measly four inches won't offend me. And I certainly wouldn't bother mentioning such a little incident to anyone."
Jack stared at his sister and brought his hands to his zipper. She just stood with her hands on her hips and stared back at him defiantly.
"I'm gonna do it," he warned her.
"Bullshit. You don't have the guts."
Jack yanked his zipper down suddenly, and Karen laughed. "Go ahead," she said. "Fish around in there, see if you can find it."
His sister's words gave Jack enough courage to reach into the opening and grab his hard cock. Karen licked her lips with anticipation. He had to bend it to get it out, but suddenly there it was, standing straight out from his pants, large and pink-skinned except for the broad, purplish cockhead.
Karen gaped at the size of her brother's prick as it majestically nodded up and down, dripping pre-cum in long, clear strings.
"Are you satisfied now?" he asked, pride and horniness battling with his self-control.
Karen decided to play the innocent, little girl. "I… I've never seen one that big," she said, her eyes wide.
Jack smiled, pleased. "Not even Bob's?"
"That piss-ant?" Karen shook her head, keeping her eyes glued to his dripping cock. She acted nervous, shifting her stance and edging nearer.
"It's awful stiff," she whispered, looking into Jack's hungry eyes. "Was… was I the reason?" She dropped her eyes and managed a blush. "But I'm your sister, Jack."
Jack, too, was edging closer, until he realized that the wet head of his prick was pressing into the warmth of Karen's rounded belly. He was about to hurriedly back away when she wrapped her arms around his neck and buried her face in his chest.
"Jack," she said softly, "it must be sort of painful to walk around like that…" And she rolled her hips, massaging his cock between their bodies.
"Karen…" Without thinking, Jack's arms went around his sister and he filled his hands with the softness of her ass cheeks.
As he kneaded Karen's firm ass, he was unconsciously working her skirt higher and higher, until soon he was clutching the cool skin of her ass cheeks. It took a little longer to work the front of her skirt up.
"Mmmmm," Karen sighed when she felt her brother's burning cock nuzzle her fleshy, hair-covered cunt. She knew if he went an inch lower she'd soak him. Slowly, she used her arms around his neck to pull him to the floor. The canned goods were forgotten.
Jack visibly tensed as he knelt between his sister's spread legs. Her big hairy pussy was parted for him, exposing her cuntlips shimmering with a coating of scented cunt juice. Her skirt was bunched above her belly button and her hips were lifting, thrusting her wet, gaping pussy toward her brother's bulging cock.
"Do I have to tell you what I want, Jack?" she whispered lewdly, spreading her thighs even wider.
"You little cock-teaser," Jack groaned, falling on top of her. She reached down and guided the fat head of his waving prick into her soaked cunt. As it slipped in, he felt the tight tube of her cunt snapping at him and he shoved as deeply as he could.
"Ahhh!" Karen groaned under her brother's plunging cock. She could feel him stretching her pussy and raised her legs and wrapped them around his waist.
"Uhh! Harder, harder!" she cried, pounding his ass with her heels.
Jack smacked his long, thick cock into her hot, stretched cunt, his eyes narrowing with lustful delight. Karen's hips were lifting as he slammed down, and dropping as he raised up. She could feel her cuntlips clinging to his thick shaft, stretching and pulling away until they caught on the base of his cockhead. Then he was driving inward again, rolling her pussylips back and into the hot mouth of her spasming cunt hole.
"Oh, God, Jack!" Karen screamed. "Fuck me harder! I need it so bad!"
Jack felt her go crazy beneath him, her ass squirming into the floorboards. Her soft, warm body writhed and bucked as he surged in and out of her happy cunt. His heavy balls bounced with bruising force against the soft bottoms of her juice-smeared ass cheeks. They were churning, ready to pump her cunt full of boiling fuck-juice!
"Ahhh, give it to me, Jack!"
Her brother fucked on and on, his ass bouncing rapidly, plunging his cock deep into her pussy. Her cunt juice splattered out and coated their pubic hairs and thighs every time their bellies smacked.
"Ohh, it's so good!" she groaned.
"Bet your ass it's good," Jack grunted, swiveling his hips as her sucking cunt swallowed his fat cock and squeezed it. He suddenly bent down and kissed her.
Karen groaned and took his tongue far into her mouth, feeling that somehow this kissing was even more exciting and forbidden than fucking. Jack licked the insides of her cheeks and twirled his tongue all around hers, then he drew his sister's pink tongue into his mouth and began sucking it.
"Ummmmm!" Karen moaned, her tongue and cheeks tingling almost as much as her pussy. She pounded her heels into his ass harder and hunched her cunt up at his plunging prick. Her older brother's fat cock seemed to have been made just for her tight cunt, and she ground up against his base as he slammed down.
"Were… uhh… were you watching in the bathroom?" she asked.
"Sure was," Jack said, not missing a stroke. "When you were training as a gymnast, I never thought you'd end up suckin' your own cunt!"
"Turned you on, huh?" she asked. "Well, how does this feel?" And she threw her legs up and locked her ankles behind his neck. "Now you can really throw it to me!" she hissed, wriggling her ass.
"Oh, Jeez!" Jack groaned. He saw Karen grab her legs behind the knees to curl herself into an even tighter ball. Now she was really open and exposed for whatever he wanted.
"Come on, fuck me!" she cried. "Throw it to me hard!"
Jack increased his efforts, hammering her soaked cunt with harder, shorter strokes. He reached beneath his swinging balls and dug his finger into the tight dimple under her cunthole.
"Aghhh!" Karen grunted, and Jack felt her sphincter close over his first knuckle. Not only that, but her cunt grabbed him as well, pulsating around his cock with elastic firmness.
Karen caught her breath as she felt her brother shove his finger up her asshole, and admired his skill. He was careful to use the ball of his finger against her sensitive, silken lining as he massaged it. Gradually, she loosened, and soon felt his palm press against the crack of her ass.
"Oh, Jack," she groaned, "that feels great! Dig it into me, big brother, scrape my hot ass harder! Fuck me, move that cock!"
"You sure got a hot, tight ass, Sis!" Jack complimented her, settling his weight down a little more. "Feels like it's eating my finger!"
"Yours is the first finger that's got up there," Karen said.
"You mean I got your cherry!" Jack grinned, plunging his finger higher and circling it slowly. He felt her hot, humid ass tighten around his probing digit. Her asshole seemed to nibble at it as if trying to draw it deeper.
"Open that blouse," Jack ordered. "I want to suck on those gorgeous tits!"
Karen used one hand to unbutton and peel apart the front of her blouse. Her fat tits quivered and wobbled with Jack's hard thrusts, and his mouth watered for a taste of the swollen nipples dancing under his eyes.
"Yowwwww?" Karen yelled, writhing sensuously as her brother filled his mouth with her soft tit and lightly bit her gristly nipple.
"Suck them, suck them!" she cried, her voice sharpening with pleasure-pain. She could see the firm, white mounds shaking beneath his handsome face and groaned with passion, for he was still plunging his fat cock and thrilling finger in and out of her holes with great enthusiasm.
"Stop, Jack! Stop!" Karen cried a few minutes later. "I don't want to come so fast!"
Jack lifted his face from her wet tits and pulled his prick from her soggy cunt with a soft, suctioning "pop". He left his finger in her ass, however, pumping and twisting it as enthusiastically as ever.
"Want to try something else?" he asked, his hard cock throbbing against her warm thighs.
Karen looked around, spotted a low bench covered with boxes and got an idea. "Help me up," she said.
She walked to the bench and with one impatient sweep of her arm knocked all the boxes to the floor. She sat her ass on it and lay back, then lifted her legs and brought her knees up to her shoulders.
Her cunt gaped, dark and wet, pouting like a toothless mouth from the center of her thick bush.
"Hungry, Jack?" she asked lewdly, clenching her butt muscles and making her red-lipped pussy pucker and ooze, as if blowing him a wet kiss.
Jack stood in front of her upturned ass, his cock jerking over her hairy cunt. It was at just the right height for him to start fucking again. Instead, he dropped to his knees and stared directly into her quivering pussy. The hot scent of her leaking cunt juice made his tongue hang out, and when Karen reached down and stretched the hole even wider he dived right in.
"Yes, Jack, yes! Ohhh… yessss! Eat me, tongue fuck the shit right out of me!" Karen's fingers tangled in his hair, holding him to her tightly.
Her eyes were wide as she stared down at his nodding head. Jack used his tongue like a paintbrush, caressing her loose pussylips and twirling around the base of her straining, over-large clit. She could feel that tender, sensitive organ quiver under its delicate tissues and dug her nails into his scalp.
"Oh, God, Jack! That feels good!"
Jack nibbled lightly around the throbbing prong of her clit, then fastened his lips on it and began sucking as he bobbed up and down over it. His lips skimmed only an inch or two before slipping off, but then he started all over again. He heard her give a deep, moaning sigh and lifted his face.
"Do I do it better?"
"Better…?" Karen groaned, not understanding.
"Yeah, better than you?"
"Yes, yes! You suck better than me, you bastard! Now get your tongue back in that hole!"
Jack grinned and slipped the full length of his hot tongue into her quaking, drooling cunt. Karen's hips bucked out of control when she felt his lips fastened around the quivering rim of her cunt. But then he was fastened around the quivering rim of her cunt. But then he was pulling out and lapping downward. He scrubbed the sensitive strip of skin between her cunt and asshole for a long time, teasing her, then raised his head again.
"C'mon," he said, "do what you did in the bathroom, suck your clit for me. I'll take care of your cunt and ass."
Karen was so excited she would have sucked a monkey's ass if he'd asked her, so she rolled up on her shoulders and bent her head down to her swampy pussy.
When Jack saw his sister's full lips wrap around her clit, he felt his balls tighten. What a turn-on! In her obscene position, her clenching cunt and winking asshole were upturned and completely vulnerable. Jack drew his fingers over them.
"That's the way, Sis," he said. "Give that clit a good sucking and I'll make you come so hard the top of your head will blow off!"
Karen groaned and tormented her sparking clit with her lips, tongue and teeth. Her nose rubbed the rim of her bubbling cunt and Jack's nose as he bent and slurped up some of her pussy juice. Then he slid down to the puckered ring of her pink asshole. That prominent opening was throbbing, expanding and contracting with the strong sensations filling Karen's pussy.
"Mmmmm!" Karen groaned as she felt the feather-like softness of her brother's hot tongue scrub across her sensitive, wrinkled butthole.
Jack loved the taste and texture of his sister's ass, and gripped her upturned butt cheeks in his hands to hold and knead them while he poked at it. He felt the tip of his tongue pushing into her tightly clamped asshole, slipping through the soft, delicate muscle and inserting itself in the satiny heat of her dark tunnel.
"Mmmhhh!" he groaned, tasting the muskiness of her tight shitter. He started sliding his tongue back and forth in the still-narrow, but opening ass channel. Karen's muffled moans were music to his ears as he rapidly tongue-fucked her asshole.
Karen was really writhing now, her ripe body shaking with the extreme pleasure of having her clit sucked while her asshole was filled with her brother's tongue. She began panting and snorting as she sucked, and Jack could feel her body rippling with joy every time he stabbed his tongue to its roots in her butthole.
Karen couldn't take much more. With a gasp for breath, she released her clit and tried to see what her brother was doing. She could feel very well, but she wanted to see…
"Ooohhh!" she wailed. "Leave it in! Leave it in!"
Jack pushed his tongue deep into her butthole and held it there with his lips pressed tightly to her winking ring. He could feel the hungry tug of her inner muscles and began curling the tip of his deeply imbedded tongue, twisting and licking at the contracting walls of her ass.
"Yaahhhh! Fuck it, fuck it," she cried. "I want to feel you in my asssss! Oh, stick your cock up there, please, Jack! I… I want it!"
Jack felt his cock swelling and burning until he thought it would burst. He'd never seen any woman get so hot she'd beg for his big cock in her ass. Jeez, if only Beth would let him play around with her asshole just once…
"I don't want to hurt you, Sis," he warned her, lifting his face and getting to his feet.
"Yes, yes! Hurt me! Shove that fat cock all the way up my ass! I want to feel it in me!"
"You want it bad, don't you?" Jack grinned, squeezing her hot butt cheeks.
"Yes! Damnit, yes!"
"Can you bend enough to lick your asshole, too?"
Karen lifted her eyes to her brother. "You're a depraved bastard, Jack. You know that? Even when we were kids you wanted to do kinky things."
"You complaining, Sis?"
"Hell, no!" She laughed. "I've licked my asshole a few times in the past."
"Let's see," he said.
Karen bent her head again and, with her knees past her ears, reached down and grabbed her ass. Her face turned red with the effort, but she managed to lash her tongue over her pink, spit-slick asshole while her brother watched and laughed.
"Great!" he said. "You think if I push down on your shoulders and neck a bit you could suck your asshole?"
"What've you got in mind?" she asked suspiciously.
"Nothing. Just thought you might get a kick out of sucking my cum out when I'm done."
"Wow!" Karen said, surprised. "That's a new one!"
"You don't mind, do you?"
"Shit, no! I've swallowed a gallon of cum in my life. But this'll be the first time I've had it second hand, and from my own ass!"
"And the first time it's come from me." He laughed. "How's it feel to be a brother-fucker? Sorta rhymes with something else, doesn't it?"
"Stop talkin' and start fuckin'," Karen said. "We haven't got all day, you know."
Jack leaned over her bent body, his hands holding her calves and pushing them even further past her head. His cock felt the steamy heat of her cunt hole and, after nudging her stiff clit, slipped inside.
"My ass, I said," Karen groaned as he pumped her pussy hole.
"Just getting my cock nice and wet again," Jack said. "Feels good, though. Maybe I oughta come here where you can suck it better…"
Karen's hand came down to fumble at his cock and he slapped it away. "Hold on," he said, pulling his wet cock from her sucking cunt. "You're gonna git it…" And he placed the broad, purplish head of his prick against the rosy, throbbing ring of her asshole.
"Ahhhhhhhh!" Karen wailed, her spine arching as her brother's enormous cockhead pushed into the tiny, wrinkled opening of her ass, spreading the tight flesh painfully.
Jack rested briefly. Only half of his fat cockhead was wedged in her butthole, but it felt as if someone had fastened a tourniquet over it! He groaned and heard Karen echo him as he leaned his weight into her ass and felt the head snap through.
He groaned again as her sphincter squeezed rhythmically, almost as if it were nibbling an ear of corn. "Here it comes!" he shouted, lunging forward and ramming his fat cock into her narrow shitter. The heat of her smooth, pulsating ass tissues made Jack realize just how much he'd been missing by fucking nothing but cunt since his marriage. Nothing in the world beat an asshole for tightness and heat. Mouths were all right, but they weren't tight, and they weren't as hot, and you couldn't go as deep. And accidents with teeth were always a possibility…
His heavy balls slapped noisily against his sister's upturned and widely spread ass with every slow, steady stroke. He wasn't going to fuck her ass like her cunt. He wanted this fuck to last. He intended to savor every hot, squeezing, throbbing moment of this buggering.
"Oh, darling!" Karen cried, clutching his lower back with her hands. "It's great! I never imagined it'd feel so good! I've always heard how awful this is, how painful… Oh, those poor women. What do they think their assholes are for, anyway? Jeez, if a good shit feels good, a good ass-fuck's bound to!"
Jack grinned and lustily fucked his sister's ass a little faster, watching his cock as he did it. He liked the way her asshole puckered out around it as he pulled back, his shaft all hard and greasy-looking, as if he'd smeared it with vaseline. Then, as he shoved back, the pink rim of her asshole sank with him, disappearing along with his cock into her dark depths.
The more he pounded Karen's hot asshole, the easier it got. The hole was as tight as ever, but she became more lubricated as her excitement grew. He felt her muscular bowels tighten around him, surrounding him with moist, throbbing heat, and for the first time in his life wished his cock was longer. He wanted to probe the very end of her ass tunnel, he wanted to shove it in so far that his cockhead bulged her throat!
"Ahh… ahh… ahhh!" Karen grunted as her brother's fat cock made her ass feel good. It jumped and jerked in her tight shithole every time his balls flattened against her widespread asscrack, and the sensations were going right to her clit!
Jack leaned his weight behind every thrust, enjoying his sister's whimpering, lust-filled face. Backing slowly out until her tight ring caught his big cockhead, he ran a finger around her slick, pooched-out asshole, then slid it up to her cunt hole.
"Like this?" he asked, stroking the oily length of her twitching clit.
"Nuhhhhhh! Oh, God… God!" she grunted loudly as he picked up her glowing red clit and twirled it between his fingers. Jack varied his torment, tugging her clit and rubbing his thumb over the head as he held it up. Then he batted it from side to side.
Karen's eyes bulged with the intense pleasure. Her asshole fluttered thrillingly around Jack's cockhead, and her gristly, burning, elongated clit was so swollen she felt it would burst like a blood-blister any minute.
Jack took his hand away, but he kept the head of his cock in her distended butthole. "Let's see you suck it, Sis!" he cried. "Suck that clit like a cock!"
He watched as his sister, her mind filled with nothing but the need to come, willingly grabbed her clit with her full lips. He lost sight of it as her nose and forehead lowered, but just knowing what she was doing, and hearing her wet, suctioning lips working over her clit was enough to make his balls ache!
Leaning away from her butt by arching his back, he was able to sink the full length of his fat cock into her asshole without knocking her head away with his stomach. He heard her moan as he hit bottom and his balls slapped against her wet asscrack. He withdrew again, faster this time, and thrust in quickly, and Karen's whole body shuddered.
He fucked her asshole hard and fast, his cock burning and his balls tightening. Her hot, tight shit-chute was nibbling and sucking on his prick like the mouth of a whore who gargled with alum!
Sweat rolled off his pumping, shaking body as he jabbed his sister's ass with his jumping prick.
Karen felt her brother stiffen and moaned soulfully as her winking asshole clamped spasmodically on his still-sliding cock. The tight squeeze made her all the more aware of how it was swelling and twitching. Then the cum began pumping out, spraying her throbbing asshole with a torrent of steaming, creamy jism. Her butthole was filling up with the burning jism as if it were an enema! Her climax hit just as Jack's softening prick was pushed out of her spasming butt with a squishy, obscene "pop". A trickle of cum followed it.
"Grab it! Grab it!" Jack yelled. "Come on, suck your ass! Eat my cum!"
He helped her get her mouth down between her asscheeks and knelt at her side to witness the kinky sight. Karen's slightly open asshole was bursting with thick, white cum as her muscles contracted, and then he saw her tongue lash out and gather up all that was dribbling out.
"Wow!" Jack exclaimed, feeling a quiver in his balls as his sister's pink tongue slid around the rim of her elastic shitter. Then she slipped her tongue into her tight, dribbling asshole.
"That's it, that's it!" he cried as he saw her lips cover her butthole. "Suck your asshole! Drink all my cum!" Once in a while the suction broke and he heard a loud, bubbling noise. Tremors slid across her body as he watched her eat his cum out of her ass. He heard her heavy breathing and snorting and his cock started to thicken.
Karen felt enormously perverted as she eased her tongue into her asshole and tasted her brother's jism. The very depravity of the act excited her. To do such a thing, and to be watched doing it, was almost as exciting as fucking. She was clutching her ass cheeks, her lips forming a tight seal around her butthole as her tongue burrowed into the cum filled tunnel, tasting just a hint of bitterness mixed with the cum. She salivated copiously as her tongue drilled into the trembling, pink rosebud of her ass and the hot walls grabbed at it. The muscles of her neck and shoulders strained and ached as she gave in to her brother's obscene request. Her hot breath bursting against her upturned asshole increased her overwhelming desire for kinky degradation.
Her butthole flowered wider from the teasing of her probing tongue, and she felt a flood of Jack's jism trickle from the depths of her brown cave. She lapped wildly at it and groaned, swallowing contentedly. She suctioned the sensitive ring, drawing out the last sticky strings of white cum and searching for more. She whimpered when it was gone, but kept right on spearing her asshole.
Jack heard her moaning continuously and his cock rose to full, throbbing hardness as he watched her body quivering. She was obsessed with her butt-tonguing, out of control and lost in some sensuous daydream of her own. Finally, he gripped her hair and forced her head up harshly.
Karen gasped and shuddered, her eyes blinking as she returned to the present. Her brother's huge cock was in front of her, nodding threateningly. She pursed her lips and looked up at Jack with pleading eyes.
"Want another drink, Sis?"
She nodded, her lips ovalled and working like a fish's mouth.
"Get on the floor on your back," he said. "I'll fuck your fat tits. I've always liked fucking tits, but Beth won't let me shoot off in her mouth, says it's too dirty!"
Karen hurried to position herself, holding her tits up and spreading her shapely legs. Her cunt glistened, a wide, deep hole framed by matted curls. Her fat cuntlips quivered, their outer edges red and swollen. Her tits and belly were covered with sweat. Her thighs slicked with both cunt juice, cum and sweat. The hot, steamy odor rising from between her plump white thighs was a dead giveaway to a blind man that she'd been fucked half to death.
She ground her ass around and pressed her palms to the big outer swells of her tits, pushing the creamy mounds together to make the sweaty crevice nice and snug for her brother's cock.
Jack gazed at his sister as her bright eyes followed the movement of his bobbing cock.
"It's beautiful, Jack," she said. "A beautiful, big, thick cock. And I want to eat it!"
He straddled her sexy body and slowly lowered himself until his fat, hanging balls brushed her lips. "Lick my balls, first," he said. "Get 'em in your mouth and start humming!"
He knelt, his knees in her armpits, as she swept her tongue over the wrinkled, hairy skin of his sac. Jack groaned as his sister paid special attention to each big ball, circling and lashing it with her hot, wet tongue. Then he groaned and jumped as she daringly darted her tongue past them and tapped with its soft tip at his asshole.
"Oh, Jeez, Sis!" he grunted. "That's it, rim me, you cocksucker!"
Karen had never licked a man's asshole before, and if Jack hadn't been her brother, and if she hadn't been so hot, she probably would never have had the nerve. But now she eagerly circled his hairy, damp shitlips and even probed their tight center.
"For chrissake!" he yelled, reaching back and pulling apart his asscheeks. "Lick my ass, Sis!"
Karen ran her tongue up and down his hairy ass crack and poked at his puckering, quivering asshole as Jack lowered himself still more. It slipped into the tight ring and he recoiled, then moved down again, trying to get more. Finally, her tongue aching from the strain of stabbing it into his asshole, she returned to his swaying balls.
This time she sucked them both inside her hot mouth and nibbled each one gently as her tongue darted from side to side. Then she sucked hard on them, her cheeks caving in and her tongue pressing toward the roof of her mouth. He felt his spongy nuts squeezed and rolled by her talented mouth and knew they were churning up a big load of thick cum for her.
"Suck me now!" he ordered, pulling back.
Karen opened her mouth and took the huge column of her brother's cock in her hands. The purplish, swollen cockhead seemed to dwarf her opened mouth. Her tongue lashed out and wrapped around it, leaving his cock glistening wetly.
Jack shoved forward. "Take it!" he cried, and watched the head of his prick disappear into her oven-like mouth. He began screwing his cock in and out, loving the slick rubbing of her soft lips over his turgid shaft. Her wet, pooched-out lips were almost nibbling his thrusting cock, and he probed deeper into the back of her throat, making her cough.
"Okay, now your tits!" He lifted enough for her to hold them up again, the nipples hard and dark on the fat, upstanding mounds. Pushing his cock down, he slid it into the silken, hot channel of her shoved-together tits. Pumping his hips quickly, he felt his balls boiling and tightening.
"Here it comes!" he shouted, sliding his prick faster and faster, driving far enough for the pouting hole at the tip of his cock to leave a wet smear on her chin.
Karen lifted her head and opened her mouth wide, as if yawning. Her tongue hung out toward her chin, trembling with anticipation. Her eyes were fixed on the swollen, puffing head of her brother's cock. She squeezed and kneaded her tits, varying the pressure of her slick, fleshy tunnel.
Then Jack groaned and held still with just his cockhead peeping from the crack of her tight tits. It pulsed and hot jism jetted forcefully into her opened mouth, filling it and causing her to swallow greedily. The next thick, white streamer of cum splashed warmly over her tongue and neck. Jack heard sloppy, slurping noises as Karen gurgled over her mouthful of gooey cum.
"Swallow my load!" he hollered, the muscles of his butt tightening as he tried to squeeze out even more cum.
Karen shoved her face forward and gobbled her brother's softening prick. Her cheeks bulged as her tongue swished it around. Thick, sticky cum ran from the corners of her mouth and, after sucking his balls dry, she released his cock and used her long tongue to get most of the remaining jism.
"Whew!" Jack grinned. "That was some blow job, Sis!"
Karen smiled wearily at her brother. Her belly was burning with the swirling cum that filled it, and some sticky strands were still caught in her teeth. "You ain't seen nothin' yet," she sighed.
