Chapter 11

Ricky stayed mounted on his sister, hung up on his own prick, and when he had stopped panting in the aftermath of his cumming, he began to slide his cock slowly in and out of her cunt, beginning again.

But the lithe young lady bridged up so deeply, hiking her lovely ass so high off the couch that his cock was angled wrong, and the next time that he pumped in the cock-knob came slipping from her cunt.

"Don't you wanna fuck no more, sis?" he rasped.

It didn't seem likely, yet she was making no attempt to get his prick back in her pussy.

"I wanna do everything!" she answered.

He looked puzzled, humping again, his cock sliding across her cunt and the head looming up in her bush, matting the blonde vee with her own cream.

"You fucked my tits and sucked my cunt and I sucked you off and you fucked me—"

Nancy was purring, giving a sort of litany of their lust.

"Yeah? Yeah?" he gasped.

She looked amused by his failure to understand.

"It felt real swell when you were sticking your tongue up my asshole, Ricky," she hinted.

He still didn't get it, naive and inexperienced young man that he was. But he was only too happy to do whatever his sweet sister wanted.

"Want me to lick your shitter again?" he asked.

"No, silly," she giggled.

He looked like he would have scratched his head, bemused, if he hadn't had both hands cupped under the cheeks of her ass, holding her arched below him.

"If it felt so nice to have your tongue up there—I'll bet it would be real lovely if you were to shove your cock up my ass, brother—"

Ricky gasped loudly—loudly enough so that the kids failed to hear their parents gasp in unison.

"C'mon, Ricky—assfuck me!" Nancy purred, grinning with wanton glee, feeling deliciously depraved.

Ricky hesitated, confused.

"Don't you hafta turn over, Sis?" he asked.

"No, you silly boy," she giggled, hiking her lovely ass up even higher.

Ricky had a moment of doubt, wondering if he might not skin his prick in that tiny passage. But then he remembered how her asshole had clung and sucked on his tongue and realized that her shit chute would be a tight treat—and, as she said, he wanted to do everything, too.

He dragged his cockhead down from her bushy vee and through her gooey groin and, pushing out tentatively, nudged the tip into her asshole. Not sure that it would fit, he shoved with a certain delicacy.

But his prick was greased from her fuckhole and his cock-knob wedged into her fudge slot easily. The head was the fattest part of his reamer, opening his sister's shit tract as his cockshaft began to follow.

His worries were groundless and unfounded—his cock sank up her shit chute smooth as satin.

Mounted in the missionary position, brother and sister were coupled in a way that would certainly have scandalized the missionaries who had invented it!

He held all of his prick up her as her bowels sucked on the knob and her snug shit chute pulled on his prick as if she were swallowing him backwards.

It was just like getting another blowjob, from the wrong end of her digestive tract.

Nancy swayed around, impaled on his prick, her haunches hung up on the hard lever. He worked his cock sinew, and as his prick jolted, he made the supple girl bob up and down on the coupling.

Her pussy jerked up, spilling out cunt cum and jizz that trickled down into the crack of her ass and washed over Ricky's surging cumbags.

"Ooooooh! I love it up the shitter!" she cooed.

Ricky was relishing that tight tunnel plenty, himself. He gripped her asscheeks and hauled up as he hammered his cock deep into her bowels.

Nancy jerked her knees up, rolling her body into a hoop, giving him easier access. His cockhead was sinking in, flaring and throbbing. It felt as if she had swallowed a baked potato whole as it smoldered in her guts.

He was angled up, his body rigid against the curve of his sister's ass as he pounded down so savagely he seemed to be trying to fuck her right through the couch and nail her to the floor of the garage.

She already had a bellyful of his cum and she wondered if his prick was up her alimentary canal high enough so that the knob was splashing in his own goo.

Her thighs clamped to his hips and her feet kicked wildly around behind his cock-screwing ass. Then she locked her ankles and rubbed her heels up and down against his asshole, as if giving him a hint of how her own shitter felt.

"Yeah—stuff me, brother! Fuck my ass off!" she gaily gurgled. "Bugger my bun to jelly!"

He hammered in and yanked back out. Her tiny, puckered asshole was clinging to his prick so tightly that he was damned near jerking her guts inside out.

Brother and sister were loving this depraved coupling equally—and it was giving their mother and father a hell of a thrill, besides.

Jack's prick was still stuck up Lorraine's cunt from behind but now she reached back through her crotch and grasped him by the balls, tugging his cock out. The knob lodged for a moment, then slurped free.

Lorraine moved her hand onto his slippery prick and guided the head up into the crack of her ass. Jack frigged up and down, then hiked his own ass up so that the angle of his cock shifted and the flaring head was aimed right into her taut little asshole.

He began to burrow in.

"Unghhh—ummmmm—ahhhh!" she gasped, wriggling like a fish on a hook. "Pack the fudge, Jack!"

Jack heaved in and filled her ass, his balls slapping in her crotch, splashing loudly as they walloped into her sodden cunt-slot.

Now Mom and Dad were coupled as their kids were, in the back passage, but in a more traditional position, standing in tandem as the teenagers, slim and supple, continued to assfuck face to face.

Jack plunged in, driving off his toes, his thighs bulging with muscle. He held Lorraine by her womanly hips and jammed his cock in and out of her shitter in a frenzy, matching the pace of his vigorous son.

Lorraine rose up onto her tiptoes as he slogged in and dropped back onto her heels as he whipped his prick out, her heavy tits flying up and down and her gently rounded belly humping in and out.

He was plowing up so deep that she almost thought that his cockhead was going to come out of her mouth.

She dipped both hands down into her groin, playing with her own clit with one hand and fondling his swollen balls in the other.

He rested his chin on her shoulder and, cheek to cheek, they continued to watch the buggering action that they were so eagerly emulating.

Nancy was rolling like a foundering ship as she soared to yet another crest.

Her feet kicked around like a clawing cat and her brother kept on pile driving up her ass, his big prick plunging into her bowels, rattling her bones.

Her knees jerked up so high that they hit her tits as she looped her limber body into a bow. Ricky was pumping almost straight down now, his prick sinking into her asshole like a weighted plumb line.

Her cunt was creaming empty and her ass seemed to be melting in an anal orgasm on his cock. Then the youth was jolting to the peak, as well.

His balls detonated and the hot enema of his slime poured into his sibling's bowels. She kicked and bucked in a frenzy, cumming harder and faster now that the thrill of feeling his goo in her guts was added to her own sensations.

They creamed off together and slowed down, descending through the ebbing spiral. He stopped humping, and her hooped-up body slowly shifted back to the horizontal, dragging him down as her haunches dropped with his stiff cock still stuck balls-deep up her asshole.

As her ass sank down to the couch, her weight was bending his prick. Ricky tugged back. He had to pull with an effort to drag it out of her sucking fudge-hole. The head popped from her shitter and his cock lay along the couch, soiled and soaking, as he bent down to kiss her on each swollen nipple, then on her panting lips.

In the kitchen, Jack and Lorraine crested again, as turned on by the sight of their teenage kids cumming together as they were by their own sensations.

Stabbing up and into Lorraine's ass, Jack lifted her high onto her toes and the geyser of his fuck-juice steamed into her guts like Old Faithful.

She cried out in ecstasy, just managing to stifle the sound enough so that the kids were not alarmed and alerted. Jack's balls were going off in her left hand and she was clawing at her empty cunt with her right hand, frigging herself off in conjunction with the assfuck.

Jack rocketed up, lifting her, then sank back on trembling thighs as she dropped on his cock. They spasmed through the peak as one. Then he stopped humping and clung to her haunches, weak-kneed and gasping.

Lorraine leaned back against his chest, her own legs shuddering spasmodically. They both wondered if the action was over—and stared into the garage.

Ricky was lifting his prick in his hand and gaping down at it, marveling to find it still fat and firm. Even in his most fevered fist fucking fantasies, he had never spilled out so much cum and remained hard.

Nancy, too, was impressed.

"You sure are horny," she purred.

Ricky looked sheepish, as if having a perpetual hard-on was sort of embarrassing.

"I been hard all day," he explained. "Ever since I saw Mom naked in the shower—"

"Oooooh!" Nancy squealed. "That's exciting! You got the hots for Mom?"

Ricky grinned bashfully and, knowing he need keep nothing secret from his sibling at this stage of the game, he nodded and mumbled, "Yeah, I sure do!"

Lorraine and Jack glanced at each other, both holding their breath and listening in fascination.

"I don't blame you, brother," Nancy said with an impish smile. "Mom's got great tits, huh? I would mind sucking them, myself."

Ricky blinked in surprise.

"Oh, I ain't a lesbian," his sister said. She licked her lips and squeezed her creamy cunt.

"Obviously."

He still looked perplexed.

"A girl can have the hots for other girls without being a dyke, you know. I love cock—but I wouldn't mind sucking a cunt, either."

"Holy cow, Sis!" Ricky croaked.

A graphic vision of his sexy sibling tonguing their curvaceous mother's pussy hit his mind and his prick lurched in response, throbbing to the workings of his imagination.

Nancy was delighted by his reaction, loving to turn him on by words as well as physical caresses.

"Sure—I'd suck Mom's cunt," she chirped. "I'd just love to have her cream in my mouth!"

Ricky's jaw was open so wide it seemed to be braced on his breastbone, and his head was slowly turning from side to side in disbelief.

"Of course, I'd adore fucking Daddy, too," Nancy added to prove she was basically normal.

The girl was saying these things for her brother's benefit, of course, and had no idea that the parents to whom she was referring were also hearing her confessions.

But they sure were.

And, obviously, they had to do something about it.
