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.
