"Keep a watch out, Pam. Do you see Mom coming?"
"Hunh unh."
Pam's brown eyes surveyed the crowded parking lot as Mark struggled beside her in the front seat of the station wagon, working his jeans down to his knees. His engorged cock flipped into the air, wagging and straining. He let out a sigh.
"Okay. Now it's your turn. I'll keep an eye out. Just hurry up, that's all."
Pam nodded and pulled her skirt up about her waist, grasping the edge of her panties. In one deft motion she arched and peeled them off, pulling their crotch stickily away from her tender heated cunt.
Mark couldn't help staring down as her dewy pussy mound burst into view, all matted and curled and tickling at her wet inner thighs.
It had been a long dull morning shopping with their mom, driving from one shopping center to another as she picked up items here and there and spent hours on end just browsing. Finally, worn out on this whole excursion, they'd begged to stay in the car and wait instead of following Linda from store to store.
And almost as soon as she'd disappeared from sight, they'd looked at each other with mutual agreement.
Pam slid the crisp moist material down her slender hips, then off. Now her pussy was bare beneath the skirt, all warm and oozy with anticipation. She reached over and grasped her brother's bobbing prick, and he grunted.
"Ahh, yeah. Now do it, Sis. Climb up on me – hurry! If I don't get my prick in you right now I'm gonna shoot all over the place! Come on!"
Still holding onto his swollen cockshaft, Pam obeyed with a smile. She wiggled onto her knees and straddled his lap, facing the window so she could see out in case their mother appeared unexpectedly.
Then, easing his cockhead against her pooched, dewy cunt lips, she lowered herself onto it.
"Oooohhh…"
A long happy groan rose from her throat as her cunt mouth stretched wide around her brother's cockmeat, sinking down on it with a spew of hot, steamy juices.
"Oh yeah, that's right, ohhh shit." Mark groaned too. His prick sank up into her, throbbing and lurching in her snug cunt.
"Uhhhmmm…"
She settled on his lap with an ecstatic flutter, her skirt fanning out to cover their actions.
People and cars were everywhere, some of them passing by so near that Mark could have reached out the passenger window and touched them. That fact only added to the thrill as he grasped his sister's hips, urging her on.
"Jesus, that feels good! Now fuck it, Pammy. Fuck it good, like that… ahhh…"
Not that Pam needed urging by this time, by any means. She began to ease up and down on her knees, undulating to feel his cock jerk and slosh inside her.
"Ohhhh… ooooh…"
Her head lolled, long brown hair tickling at his face. Her tight wet pussy made slick sucking sounds around his aching prick as she rocked rhythmically, riding it like a bronco.
He gave an approving grunt, reaching under her skirt to feel all that soft thick cunthair split apart by his cock, fingertips exploring around until they located the taut stretched button of her clit. He rubbed it furiously.
"That's real good, Sis. Pump the jizz right out of me, so I can shoot it up your cunt hole! Faster… faster!"
"Uuunnnggh…"
Pam obliged gladly, her clit shooting off sparks under his twiddling fingers. She humped up and down harder, until her pussy glided along the entire length of his massive veined pecker. The seat springs squeaked frantically as she bounced to climax on her brother's cock, slamming down with furious delight.
"Ohhh – oh fuck, I'm coming Mark! I'm coming on your cock! Now… now… now – ooowwwhhh – mmumppff!"
Her wail was cut off as Mark slapped a hand over her mouth. At the same time he lurched and his cock spasmed.
Cum fountained up Pam's taut pussy, and she careened on it in wiggling ecstasy as its hot floods pumped her to completion, gasping and moaning into her brother's clamped palm.
"Muhhhm… ummppfff!"
"Aaahhh…"
He groaned, releasing his grip as the jism was sucked from his balls. Pam wavered atop him, her pussy filled with thick hot gushes.
"Oh shit, Pammy, that… that was something else! Ohhh, fuck!"
He sank back, drained and happy.
Pam slumped too and her cunt squeezed on his pecker until it finally slid free with a limp wet plop.
Splatters of cum seeped from her bloated hole, and she collapsed on the front seat in a sated heap, skirt bunching about her hips to display the slick crease of her pussy drooling his jizz, its brown fuzz dewy with big white globs.
Mark grinned. But then his grin froze when he glanced up and saw a familiar package-laden figure heading toward them, only a few cars away.
"Oh shit – it's Mom!"
Frantically he jerked his jeans up and snapped them together, then pulled his dazed sister upright and shoved her panties under the seat.
Pam slipped back to reality as the driver's door opened, and their mother climbed in.
"Well, did you have a nice wait? I didn't mean to be so long but it – uhhh, well, it… doesn't matter. Take these, Mark."
Linda's smooth conversation broke into a stammer as the tangy reek of sex filled the car, and she pushed the packages in Mark's lap in an effort to hide her shock.
But it was all too plain to see what had happened, even if she hadn't smelled it. Mark's flushed face, and Pam's discreet glowing expression gave it all away.
Her children had been fucking. And right out in public. Right in the middle of her shopping trip! Linda was too stunned to react. Instead she started the car and headed home, not knowing what else to do.
All the way back, none of them spoke. If they noticed their mother's abruptly quiet behavior, neither Mark or Pam seemed to realize that they'd been caught. Instead they sat obediently, both looking as innocent as two children ought to look.
But Linda knew better. After the initial shock wore off, turmoil set in. She honestly didn't know quite how to react, or what to do about it. Now that they'd discovered sex, how was she supposed to stop them from wanting to learn more?
But even in her turmoil, she knew exactly who was responsible for doing this to her children. She'd seen it last night, with her own eyes. Susan. That… little… bitch!
As she drove, her fury grew. Not at Mark or Pam, because she knew her kids. She knew how innocent they were compared to so many others their age, and how easily their teenaged emotions could be unleashed at any moment with a little direction. And it was growing painfully obvious that Susan had been doing plenty of directing.
By the time she pulled into the gravel drive by the house. Linda was fuming. Something had to be done about this situation right now, before it got any worse. Somehow, she had to undo the damage her niece had done.
As the kids got out of the car and started inside, she spoke up without taking time to think.
"Mark, would you wait a second? I have another chore I forgot about, and it's going to take a man's help. Do you mind?"
"Uh… okay Mom." Giving in with a shrug, he climbed back into the station wagon beside her. "What do you need?"
"You'll see. Just wait." Unable to think up any fancy lies, she stopped his questions shortly and pulled once more out of the drive, not exactly certain where she was going.
After a few minutes of guiding the car down back roads away from the house, Linda saw a familiar-looking dirt lane and abruptly pulled in.
"Hey, Mom?" Mark frowned, perplexed. "This road doesn't go anywhere but to a cornfield. What's up?"
Not answering, she found a shady spot and brought the car to a halt. Then, when she'd killed the engine, she turned to face him. "That's exactly what I was going to ask, young man. What's up with you and Pam that the two of you feel called upon to fuck each other right in the middle of a busy parking lot? You did it, didn't you? You fucked your sister – after promising me you wouldn't!"
Mark's mouth dropped open, and his eyes bulged.
"And don't bother trying to lie, because I already know the truth!" Linda was infuriated, her cheeks flushing hotly. She was getting herself worked up, and couldn't seem to stop it. "Answer me, young man! You fucked my Pammy, didn't you? Didn't you?"
Suddenly she clutched Mark's arm in an iron grip, making him wince.
"It… it was sort of an accident. Ouch Mom, that hurts!" He tried to pull away, his face pale. "Accident!" Linda's voice rose almost to a cry, and she shivered with anger. "Accident? You mean you slipped, and your cock just fell right into her? Is that the kind of accident you're trying to make me believe, Mark Harmon? Susan caused this, didn't she? Don't try to hide it. She's the one who got you two started! She got you all horny and was showing you how to fuck your sister last night when I walked in! And now you've done it, after promising me you wouldn't! Isn't that how it was? Isn't it?"
In her fury she gave him a shake, and Mark's answer rattled out. "Well… sort of, I suppose…"
"Sort of!" Linda vaguely realized that she was getting carried away, but couldn't stop herself. "You sort of fucked Pam, and no doubt you've sort of fucked that bitch Susan as well! My God, you just won't be satisfied until you've fucked every woman in the household! And that includes…"
She stopped, suddenly aware of the subdued ache that had grown in her cunt from the first moment she'd whiffed that raw tantalizing aroma of sex. Her pussy was frothing, drenched and hungry.
She needed fucking right this instant, and she needed it bad. She'd practically blurted it out in so many words, though her son was too scared to notice.
His face pleading, Mark took her momentary silence to break in. "Honest Mom, we didn't mean anything by it! We were just… just having some fun, that's all. Learning stuff, like, like the kind of stuff you don't learn from your own folks! That's all it was, I swear!"
His argument was far from convincing, but Linda knew that in his own naive mind he meant it.
She took a deep breath, then answered in a chill tone. "I see. You and your sister learned about fucking because your father and I didn't teach you all about it ourselves, is that it? Well, I'm going to teach you now. Oh yes I am, since that seems to be just what you want. Strip out of those clothes young man, because you're about to learn a lesson you'll never forget."
If Mark had been taken by surprise before, he was thunder-struck now. "What?"
"You heard me perfectly well, and we both know it! Get those clothes off this instant, before I strip you myself!"
The threat in her voice was so ominous that his fingers quickly leaped to his shirt, popping its buttons one by one.
After a moment's hesitation, Linda did the same. Her hands were trembling with a whirlpool of emotions as she undid her blouse, letting it drape open. With quick, cool efficiency she pulled it off, then undid her bra as well.
Mark stared, aghast, as the white cups fell free and his mother's big tits sprang up, jiggling and bobbing, their huge, swirled areolas like two wide, bulging eyes.
It all happened in a daze, as if he were dreaming it. His shirt peeled off, and he unsnapped his jeans. For the second time that morning he wiggled them down, baring his wilted prick and sagging balls, then kicked his feet out of them entirely.
At the same time his mom did exactly the same with her slacks. She arched and jerked and pushed all at once, and they peeled back. Her glossy red cunt fur popped out all spongy and glistening in the sunlight, giving him an even better look than he'd had last night.
She worked the slacks to the floor of the car, then turned to face him with a cool green-eyed stare. "If I'm going to teach any son of mine all the disgusting things he's so eager to learn, I'll need some room. We'll do it in the back, where at least we can be comfortable."
Forcing herself not to stare down at her son's soft, enticing prick, she swiftly twisted around and climbed over the seat onto the mat that spread across the expansive back end of the station wagon.
For an instant her taut round ass jutted by his face, and Mark actually saw his mom's pert little ass winking moistly at him. Then, with a flash of long pale legs, she was over the seat and out of sight. Her voice drifted back, a cross between a threatening purr and a pleading whimper.
"Come here, Mark. Your lesson's long overdue, and it's time you learned it! Come here this instant, young man!"
He gasped, his head whirling with so many different emotions at once that they dizzied him. "Jeez-us!"
Then he scrambled obediently over the seat, not daring to disobey her again.
Linda's legs were spread out wide, and the first thing he saw was his mom's cunt gaping before him, its lips all pooched out and drooling hot juices right in his path.
It happened that quickly. Her son sprawled over the car seat, gaping at her open pussy, and Linda reacted without thinking. She grabbed his thick hair with both hands and pulled his head down.
"This is what you want – look at it! Look at my pussy, Mark! Get a good look. I want you to get your fill!"
With those chilling words she arched, forcing his head down in the same motion.
Suddenly Mark's lips were mashed against wet, slippery cunt flesh. The juices smeared his face, its fat creased mouth smacking at his chin. That abrupt act made him hiss, and his mouth opened.
"Mppff – Mom – Muhh – hummppf!"
His tongue jabbed out automatically, and flicked across his mother's pussy. Hot juice poured over it and she clutched his head with a groan.
"Oh God, yesss! Eat me, damn it! Eat me out, you horny little bastard! I'll teach you just what pussies are for – eat it! Ohhh, oh fucking yes!"
Though taken by surprise, he responded naturally. With that first taste of cunt cream tingling on his mouth, Mark lapped out again. His tongue slapped all the way up and down his mom's greasy cunt, plowing between her flared cunt lip folds and swooping up the cream that poured out of her.
That eager slapping probe tore across her fat, oiled clit, and she soared up in a spasm as pure jolts of pleasure surged through her.
Linda wasn't behaving very motherly at all by now, and in a vague, guilty way she knew it. But things had gone too far beyond simple motherhood by this time, urged on by her own anger. And the first jabbing strokes of Mark's tongue had her wrenching up in delicious waves of delight, swept along in a tide of bliss that had her hunching urgently and twisting her fingers in his hair, grinding his mouth to her cunt even harder. "Yes! Get your tongue up my pussy, Mark, eat me out good! That's it, lick up my juices and gobble them all down, because I've got lots more where that came from! Ohhh baby, ream me out! Ohhh, Godddd!"
She let out a delighted wail as he followed instructions to the letter, lapping her moist tender cunt folds and then diving his tongue between.
Despite all his experiences with Pam and Susie, Mark hadn't been prepared to find himself eating his own mother's pussy. But he was doing it now, and from his mom's shuddering reactions he seemed to be doing it just right. His tongue raced out of her musky cunt hole to flick the fat bud of her clit and dip along her entire pussy gash, then raced back into her again. Plunging in and out like a cock, fucking his mother with fast jabbing strokes that had her twisting and mewling in the back of the station wagon, he plastered his face to her cunt with greedy slurpy sounds.
He nuzzled into all that wet pliant pussy flesh with a fury now, totally caught up. His eager probe plunged deep into Linda's thrashing cunt, and she hunched up to meet it.
"Yehhs, do it like that! Give it to me, nice and fast! Tongue my pussy all the way, you sister-fucking little bastard! Yes, yessss!"
Just the sight of her son crouched between her thighs gnawing at her heated cunt was enough to send her wrenching up in the first bursts of orgasm. His tongue darted between her cuntlips with frantic need, lunging into her with fast wiggling stabs. She hunched even harder, exploding in a sudden burst of climax that wrenched her up with a vengeance. "Yesss! I'm coming, eat me good! Good damn it, good, go – ooooohhh! Aaaannnnh!"
Her ass bucked and her pussy smashed against Mark's face as he slurped his tongue in and out of her in rapid-fire jabs, reaming her to orgasm.
Linda reeled, pouring a flood of cunt juice over her son's mouth. She came in rippling surges of uninhibited release, until every fire-cracker of bliss had burst inside her. Then she pulled his head roughly up, jerking him toward her.
"You… you sweet mother-sucking baby, that was a good start! But I've got a better punishment than that in mind. Get up here and give me just what you gave Pam! If you've got the balls to fuck your own sister, then you can damned well do it to your mother! Get it in me this instant Mark – now, nowww!"
Jerking him to her with a painful twist of his hair, she swooped down with one hand and clutched his throbbing prick.
"Oh jeez…"
Mark scrambled atop her gladly, his cock now so stiff and sore that it felt as if it might explode right in her hand at any moment. He sprawled between her wide-spread thighs and his prickhead dove hard against the wet, hot flesh of his mom's sopping pussy.
She guided his cock deftly between her flared cunt lips, and let out a squawk as it slid into place and slithered up her cunt hole.
"Unnnh! Oh fucking yes, that's how I want it! Fuck me, just like you did Pammy! Dick my cunt!"
He crashed atop her, and his cock sank to its base up her pussy. Instantly their mouths crushed together, and Linda groaned between her son's lips as she licked off the warm film of her own cunt cream up and stabbed her tongue down his throat.
Mark's cock began to piston in and out of her with machine-like strokes, his balls tickling the crevice of her ass with every thrust. She hunched up to meet him, her pussy lips snapping with rubber resilience about his veined cockshaft. With all the fury of an insatiable mother she fucked herself onto her son's meaty prick, abruptly pushing his head down to one of her big, taut-nippled tits.
"Suck my tits, you bastard! Suck me and fuck me just like Pam! I'll give you all the fucking you can take, if that's what you want! Do it! Do – ooooh! Yes, yessss oh fucking baby, give it to me nice and hard!"
Mark sucked greedily on the huge bloated nipple that shoved into his mouth, catching it in his teeth and chewing as well. Her pussy slid up and down his greased prick with such intensity that he didn't have to pump at all, but he did just the same. Suddenly it was fun to make his mom scream after the way she'd just treated him. It was fun to bite down on her big nipple a little extra, to piston his cock in her pussy with a strength that smashed her ass against the mat.
She wailed and sobbed, humping all the harder. He sucked on her tit until its rubbery hardness was crammed deep in his throat. He fucked his cock, the thing that his mom wanted, just the way she wanted it.
"Oh God, God that's fucking sweet! Stick it in me lover, stick it in me good! Fuck me just like that horny slut cousin of yours, so I can feel your cum in my pussy! Ohhh, oh my God honey, you're making your mother come! I'm going to come, sweet baby give it to me faster! Faster! Guhhh – gunnnhhh – gaaaaahbhhhh!"
Bouncing with a ferocity that bobbed the whole back end of the car, Linda soared to climax. It was like nothing she'd ever known before. Perhaps because it was her son's precious young cock that was making her come, she came in a spiraling bliss that seemed to explode up and up forever, drilling her totally onto his pounding prick.
"Aaannnggghhh!" she screamed, twisting and bunching in sheer unbelievable waves of utter bliss.
That was all Mark could take. He slammed down onto his mother's heaving, voluptuous body, and let his load of jism erupt inside her.
Caught at the very peak of her orgasm, Linda shrieked as her son's hot cum spurted into her pussy, unloading blast after searing blast. She took it all, and hunched for more. Her legs wrapped around his youthful, pumping ass, and she writhed in unleashed luxury.
"Aaannh – aaaahh – ahhhhh, yehhhhssss…"
Purring in utter abandon, she sank back on the floor twitching with release, as Mark's cock continued to splatter the last of its dregs deep inside her. At last he collapsed, panting.
"Oh Mom, oh shit…"
"Uhhhm…" Linda clung to his sweaty body, her cum-filled pussy refusing to release her son's slumping prick. "Ohhh, baby… good, so fucking good…"
Mark couldn't have agreed more. He nestled against his mom's gasping body and heard her giggle.
"Now… now isn't that better than fucking your sister? Or even your cousin, for that matter?"
He had to nod, his hands stealing over his mother's huge, pliant tits. "Yeah Mom, it was… oh fuck, it was fantastic!"
Linda laughed softly. With his cock snuggled warmly in her cunt, she couldn't feel even a twinge of guilt. "And if I ever catch you sniffing around the girls again, we're going to have this little conversation again! Do you understand?"
For the first time, Mark really did understand. Hell, his mom was every bit as hot as Susie! Maybe even hotter! "Yeah, I understand. Whatever you say, Mom."
"Ummm, good. And if you need any reminders, just come to me first. That's what mothers are for, baby…"
What this mother's for, anyway, she thought. And the thought made her smile.
