"Why, Kenny! What on earth do you think you're doing on that thing?"
Cheryl's eighteen year-old kid brother was sitting on the exercise machine in his bedroom, stark naked, grimacing as he worked his way through a set of leg raises. He let the weight fall and looked at his sister sheepishly as she walked in.
"Oh, hi, Sis. I was just trying to iron out a few kinks, that's all." He smiled unconvincingly. "The knee's starting to feel a lot better, Sis! Really! I mean, all I've got to do is get the blood flowing in it, and I hardly know it's hurt at all!"
"That's nonsense, Kenny, and you know it. You know the doctor told you that the best way to treat it is to just lie right on your ass in bed and let it heal itself."
"But it seems so silly! I can walk fine."
"I don't care if you can do jumping jacks, Kenny! The only reason we're going to Metro City is to get you onto the college varsity team. And what you can't do while your knees still hurts is kick like you used to. So get off that machine and get in bed this instant!"
Kenny sighed, then obediently slid off the exercise machine and walked stiffly back to the bed.
Cheryl smiled warmly again as the naked youth slid onto the sheets, bunching several pillows behind his back. And she glanced automatically at his big, meaty prick as she sat beside him on the mattress.
"What it needs is surgery," Kenny mumbled.
"Yes, I know that, dear," Cheryl sighed. "But we just don't have the money for any of that stuff. The next best thing is bed rest. Now, I want you to keep being optimistic, Kenny. I'll find a job in Metro City that'll pay rent money and your tuition in college. All you've got to do is keep that leg healthy so you can impress Coach Walsh at try-outs and get onto the varsity team."
"All right," Kenny sighed dejectedly.
"Oh, honey, you're just tired of lying round doing nothing, aren't you? Now, let me just rub that knee of yours and see if I can't make it feel better all by myself."
Cheryl leaned across the bed, her enormous tits jiggling in her uniform top as she gently started rubbing her kid brother's knee. Kenny sighed pleasurably, enjoying his big sister's soft touch. Soon, his prick started getting stiff, swelling in lewd little jerks on his thigh.
"Oooooh, you like the way big sister rubs your knee, don't you, Kenny?" Cheryl giggled. "Something big and juicy looking sure is getting stiff in a hurry!"
Kenny just blushed sheepishly, saying nothing as his cock grew completely hard, throbbing stiffly over his navel. Kenny was slightly built for his height, and it surprised many to learn how well he could hold his own on the football field. What was even more surprising, Cheryl felt, was the size of his cock. The teen's cock was simply enormous; a long, fat fucker that Cheryl adored to suck and fuck. No matter how many pricks she sucked, she knew her favorite prick of all would always belong to her little brother.
"Maybe your knee isn't the part of your anatomy that really needs attention."
Cheryl stopped rubbing his knee, slid her right hand up and wrapped it firmly around the blood-beating root of his huge, quivering pisser. Kenny groaned as his big sister started beating his meat for him. He settled low on the bed, spreading his thighs, dazedly watching her glide her skilled fist up and down on his bloated fucker.
Cheryl had started sucking on her kid brother's cock shortly after his eighteenth birthday. Only a few weeks had passed since the deaths of their parents, and she supposed the shared, hysterical need for emotional support had driven them into each other's arms, and had broken down the psychological barriers against incest.
It had been one night while tearfully hugging her baby brother that she'd felt his enormous hard-on throbbing against her thigh. With her natural hunger for sucking pricks and swallowing cum, Cheryl had automatically taken Kenny's prick out of his pants for a long, loving cock-sucking that very night.
She'd been blowing his boner and swallowing his jism every day ever since. As hard as she tried, Cheryl couldn't find anything really wrong with the practice. Kenny had been over eighteen when they'd started, after all; it wasn't like she'd seduced a child.
And the simple fact was, her own little brother had the best-tasting cock she'd ever wrapped her lips around in her life. She knew Kenny enjoyed getting regular suck-jobs from her. It wasn't every boy who had a sexy big sister with such enormous, suckable tits, let alone one who'd suck the cum out of his prick.
"Want me to put my mouth on it now, Kenny?" Cheryl panted.
By now she was jacking his big prick so fast that her fist was a blur. Her feverish meat beating rhythm had already made plenty of precum ooze out of his cock head, coating the spongy cock knob with a sticky sheen.
"Ooooh, your big boner's sure leaking a lot of stuff now, Kenny! Want me to start sucking it for you?"
"Yes!" Kenny gasped. "Oh, yes, yes!"
Cheryl opened her mouth wide, plunging downward, hungrily slurping the first several inches of her kid brother's mammoth fucker between her wet, stretched lips. She clasped her mouth around his cock, shutting her eyes in her eagerness to block out all unrelated thoughts. Then she started nursing on her kid brother's hard-on with a wet, insatiable intensity, hearing her own slurping, gurgling sounds fill the bedroom as she sucked feverishly on the bay's big, oozing pisser.
Kenny looked down at her dazedly, seeing how red and puckered her cheeks looked, a sure sign that his big-titted sister was completely lost in the tender art of cock-sucking. Up and down Cheryl bobbed her head, her enormous tits quivering in the uniform as she shamelessly fucked her mouth with her young brother's prick.
The youth's boner grew progressively stiffer, pulsing on the roof of her mouth, oozing out a steady flow of hot, sappy pre-cum. Contentedly, Cheryl swirled her tongue over and around his pulsing, mushroom-shaped cock head, thrusting her tongue teasingly into his piss hole, wanting to taste every drop of his jizz.
"Do you like the way I suck, little brother?" She popped his prick out of her mouth long enough to give him a teasing look, a strand of saliva hanging luridly between her lips and his cock tip. "Ummmmm, it sure is awfully stiff and sticky now, Kenny. Do you want me to suck really hard now, and make this big boner start squirting?"
Kenny just stared at her, obviously too excited to speak. Cheryl opened her mouth as wide as she could, again plunging her face into his hairy crotch, this time sinking even more of his prick between her lips.
The cockshaft was so swollen that it felt thicker than her wrist, and there was so much pre-cum oozing out of his cock head that it was like licking tasty juice out of a split orange. Cheryl swirled her tongue insatiably around his cock head, swabbing it, coating it with spit. She tightened her fist around the root of his cock lance, then started beating his meaty hard and fast again, her fist a blur as it whipped up and down his prick.
"I'm cumming!" Kenny cried in a choking voice. "Unnngggh! Suck my dick, big sister, suck my stiff, fucking cock! Unnnngggggh! Cumming!"
The kid's mammoth boner started to spew, blasting cock cream onto the roof of her mouth, spraying thick gobs of cum down his horny sister's throat. Eagerly, Cheryl clung to the jizz shooting pisser, jacking and sucking cock as hard as she could, determined to milk down every drop of her kid brother's jizz.
One of the things she loved best about sucking off her little brother was how much cum he always shot off! Her kid brother always shot off big, sometimes spurting forth so much of the tasty, salty jizz that she had to swallow as fast as she could to slurp it all down. And he was cumming the way right now, Cheryl thought, as she insatiably sucked and beat the squirting cock lance, gulping down the frothing white jism until she'd completely drained her kid brother's balls.
"Umm, that was a nice big one, Kenny," Cheryl said. She held the big pisser in her right hand, jacking on the spit-dripping cockpole just hard enough to keep the blood in it. "And it's still awfully stiff too, Kenny. Do you think your knee would feel even better if I let you give my itchy little pussy a good fucking, too?"
"Yeah!" Kenny grinned.
"All right, little brother. Let me just get out of this uniform."
The busty blonde teenager slid off the bed, staring obsessively at her brother's cock lance as she started to strip off her uniform. She wasn't fondling his cock anymore, but she knew the sight of her spectacularly busty bare body would make his cock stiff again, if it went down at all.
Quickly Cheryl pulled off the uniform, leaving herself naked except for her bra and panties. Her brother's boner pulsed over his belly as she undid the bra, letting her enormous, red-rippled tits jiggle and sway spongily on her chest.
"Gosh, Kenny, sometimes I think you're the biggest tit freak I know," Cheryl giggled. "I mean, I know I've got a set of really big ones, but your cock always just stands straight up every time you look at 'em!"
"I know!"
"I think you might have a hard time finding a girl to settle down with, little brother. I hope you don't expect her to be as busty as I am."
"Shit, I don't care if she's flat-chested!" Kenny grinned. "I'll just keep coming over and visiting you instead!"
"Oh, Kenny! What a thing to say!"
Then Cheryl wiggled out of her panties, realizing that her cunt was so wet and juicy that the crotch band stuck stickily to her cunt fur. That usually happened when she sucked a nice, spewing load of cum out of her kid brother's boner. Kenny's prick juice was so warm and tasty that she could almost cum without touching herself, just from sucking his prick and swallowing his jizz.
Now her cunt was throbbing and aching, the pouting pussy lips pulsing in and out with her need to get fucked. The petite blonde sprawled on her back beside her brother, her huge tits slowly rolling to a stop on her chest. She stared at his boner as she splayed her legs wide, opening her curly-haired cunt for the invasion of a nice, big prick.
"Kenny, why don't you lick it a little first?" Cheryl panted impulsively. "That way, my little pussy'll just be burning for you to put your cock into it!"
Kenny grinned, then obediently sprawled on his stomach between his big sister's legs. He spread her thighs wider, helping her drape the backs of her knees over his shoulders. Cheryl shuddered and bit her lip as she felt the first pressure of his wet, swiping tongue between her pussy lips.
"Ooooh, Kenny! That feels so good!"
She slid her hands down, delicately peeling apart her pussy petals with her fingers, exposing the bright, juice-glistening pinkness of her cunt interior, and the fat little bud of her clit. Kenny hungrily started licking and lapping, his cock pulsing between his belly and the bed as he savored the musky aroma of his sister's wet, ready-for-fucking pussy.
In and out his tongue fucked, thrusting as far up her cunt as he could shove it in. Then Kenny settled into a steady, up-and-down rhythm, lovingly lapping the pussy oils from the oozing depths of his sister's cunt slit.
"Unnggh, Kenny!" Cheryl's giant tits started jiggling again as she humped her round little ass off the bed, hungrily thrusting her wet, throbbing pussy on her kid brother's face. "Now lick my clitty, Kenny! Unnggh, unh! Lick it for me, lick it really good!"
Her clit was fat and protuberant, tingling and aching with its need for a nice, hard licking. Kenny pressed his tongue on the underside of the nubbin, making his big sister's thighs twitch against his cheeks. Then he started licking the pulsing little clit bud expertly from side to side, sending waves of intense pleasure coursing through her naked body.
"Oh, Kenny!" The naked sister's tits jiggled as she humped her bare ass furiously off the bed. "Lick it for me, Kenny! That's right! Oh, lick me, lick me good!"
Kenny straightened two fingers, gooshing them into the narrow, clasping interior of his sister's spasming fuck-channel. Rhythmically, he started fucking them in and out, making his busty big sister hump her ass even more frantically off the sheets.
He took her clit into his mouth, sucking gently but forcefully, puckering his cheeks around the sensitive nub. Cheryl cried out with pleasure, arching her hips off the sheets as the cum spasms burst through her loins.
"Suck my pussy, suck my horny pussy!" she cried. "Unnnggggh! Cumming now, Kenny! Suck, my cunt, it's cumming!"
Her aching pussy burst violently into orgasm, throbbing on Kenny's mouth, her cunt channel sucking and gripping needfully around his fingers. Again and again, the heat of cumming pounded through her pussy, until Cheryl thought she might pass out with the sheer intensity of her lust. But her horny kid brother kept sucking and finger-fucking her, guiding her through the delicious delirium of her orgasm.
"Oh, gosh, Kenny, that was a really good one!" Cheryl panted. "Now hurry up and fuck me, little brother! My pussy needs your big prick!"
The sucking had left her pussy hot, swollen, and slickened with a lewd mixture of pussy juice and spit. The pouting pussy lips pulsed in and out with Cheryl's need for a long, hard cunt drilling from her brother's giant pussy-pleaser.
Kenny rose to his knees, smiling at his sister, licking the pussy juice from the corners of his mouth. He held his cock in his hand as he loomed up in position between her spread thighs, aiming his blood-beating cock head at her gooey fuck-hole. Again, the horny blonde stared down the valley between her enormous tits, wriggling her ass as she watched her brother fitting his cock head into her cunt.
"I can feel it going in, Kenny! Ooooh, it really feels fat!"
Kenny pushed his big cock lance up his sister's juicy cunt, sighing with pleasure as he felt the glove-tight fucking channel spasm welcomingly around his cock meat. In and in the boy's immense boner pushed, giving Cheryl's cunt the big, meaty pussy-prober to suck on that she'd wanted. The big-titted blonde started humping when half the cockmeat was stuffed inside her, eagerly thrusting her hot fuck-hole onto the satisfying stiffness of her young brother's cock.
"Unngggh! Feels so good, Kenny! Awwww, fuck my pussy, fuck my horny little pussy! You know I love it, Kenny! My pussy loves your cock so much!"
Kenny grunted, coming down hard, ramming every inch of his blood-beating fucker up his sister's pussy in one hard stroke.
For several seconds, he lay flat on her naked body, crushing her big tits under his chest, letting her tight, stretched pussy suck and spasm around his prick. Then Kenny started fucking his horny sister, fast and hard, making the bed squeak beneath them as he rammed his huge fucker in and out of her buttery cunt slit.
"That's right, Kenny! Unh, ungh, unh! My pussy's getting really juicy now!" Shamelessly, the naked teenager humped and wiggled to meet her brother's rhythm. "Fuck my tight pussy, Kenny! Unh, ungh, unh! Fuck my horny pussy just as hard as you can!"
Kenny picked up the pace of his fucking, panting on his sister's shoulder as his huge prick soaked in the buttery juices of her cunt. In and out his massive fucker sawed, spearing deeper into her pussy with every savage thrust.
Cheryl's expression contorted with the intense pleasure of the incestuous fuck-session, feeling her juice-oozing cunt hole beginning to suck and contract around her brother's prick. She twined her arms tightly around his shoulders, clawing his back in a desperate attempt to make him shove his boner even harder and deeper inside her.
"Kenny – think I'm gonna cum now!" she gasped. "Unngggh, oh fuck, my little pussy's getting super itchy now! Need hard fucking, Kenny! Unh, unh unh, oh, yes, ram my pussy, ram my horny little pussy! Oh, Kenny, I'm really gonna cum hard!"
Kenny started fucking his horny sister as hard as he could, relentlessly ramming his boner in and out of her cunt. Cheryl felt the luscious heat of cumming mounting deep inside her belly. Suddenly the orgasm exploded through her loins, making her nipples tingle and her asshole pucker, her expression contorting obscenely with need as her cock-stuffed pussy sucked and gripped around her brother's prick.
"I'm cumming, Kenny! Fuck my cunt, fuck my horny cunt hole! Cumming, cuuummmiiinnngggg!"
Kenny kept fucking his sister's cum-throbbing pussy as hard as he could, guiding her through her orgasm. Then he suddenly rammed his prick to the hilt in her cunt, shuddering as his balls vented another load of spewing cum.
Cheryl felt his cum-load spouting and streaming deep inside her, showering her aching fuck channel with a soothing sheen of jizz. Feverishly, she kept wiggling and humping beneath her naked, horny kid brother, flexing her fucking muscles around his cum-squirting prick, helping him to drain out every droplet of cock cream.
