CHAPTER THREE

"Oh, Mark," Sharon said, calling to her son as he passed the open door of her bedroom. "Would you mind coming in here for a minute, please?"

Mark entered his mother's bedroom, blushing slightly as he held the towel around his waist, his wet hair dripping onto his muscled shoulders. She had timed it perfectly. Ever since her late husband had died six months before, Sharon had found herself growing progressively hornier for her handsome son. Now she'd finally decided to seduce bin. She felt as if she couldn't survive another day without tasting the meaty stiffness of her own son's cock.

"What is it?" Mark asked, sounding nervous.

"Darling, Mommy’s back is all sore again," Sharon purred. She was lying naked on her stomach on the bed, the sheets bunched in a false imitation of modesty around her slim hips. "I guess it's just the penalty of carrying around these enormous tits of mine all day. Would you mind giving me another back rub, honey? It would really help me fall asleep."

"I - - maybe I ought to put on my boxers first," Mark murmured.

Sharon giggled. "Oh, darling, you're such an adorable prude! Mommy’s not going to see anything if you just sit on my rear end and give me a back rub. Come on, Mark."

Mark hesitantly crossed the room, his handsome face screwed up into a slightly worded expression as he joined his mother on the bed and sat on her upper thighs. Sharon sighed and rested her cheek on her folded forearms. Her enormous, creamy-white tits pressed on the sheets. Mark would be staring at the spongy softness of her tits as he rubbed her back, and that, she was sure, would give him a hard-on. The towel wouldn't provide much concealment.

His fingers trembling slightly, Mark started to massage the strong, feminine muscles paralleling his mother's spine. Sharon sighed and smiled as she felt the wet need throbbing steadily in her cunt. It wouldn't be long, she thought, before they were fucking - - fucking wildly, ecstatically, her tits quivering and her ass heaving off the bed as she joyously gave her pussy to her own son.

Any man she knew, would have been eager to take her son's place. Her wide-eyed, soft cheeked face, framed by girlishly short brown hair, had remained youthful and supple, though she was now in her late thirties. Sharon had been blessed with the best legs, the roundest ass and, especially, the biggest, ripest tits in all suburbia. Only her friend Emily had a set of tits to rival her own, and Sharon knew that merely venturing outside in a tight sweater would make every cock in the neighborhood grow painfully stiff.

She could have had any man, but Sharon wanted her son. It had begun when she'd seen how obsessively he stared at her tits, watching them bounce when she did housework without a bra. Sharon had then begun to dress provocatively on purpose, and that was when she'd noticed that Mark would frequently develop a giant, throbbing hard-on while looking at her. Sharon had finally begun finger-fucking to thoughts of her son, first once, then twice, then countless times each day, imagining herself lovingly sucking the juice out of her son's swollen cock.

"Mark," Sharon said finally, wriggling beneath him. "Would you mind - - well, this sounds naughty, but would you mind rubbing my ass a little? Please?" His hands stopped moving on her back. "It really does hurt all the way down there when I get backaches, darling," Sharon purred reassuringly.

"Okay, Mom."

He slid off her thighs and waited as his mother kicked the sheets to the foot of the bed. Then Sharon heard his sharp intake of breath, and could practically feel his eyes boring into her ass-cheeks. If anything could rival her enormous tits, Sharon thought complacently, it was her ass.

Mark's hands trembled as he laid them on his mother's ass. Sharon shuddered as he kneaded her ass, rolling her ass-cheeks under his fingers. She was sure he could see her hairless pussy, peeking out under the cleft of her ass, and perhaps even her puckered little asshole too.

"Rub my front too, Mark."

This time she didn't wait for permission. The wanton mother rolled abruptly onto her back, feeling her giant tits quivering as she now faced her son. Mark gaped at her. Helplessly he ogled the spongy, resilient texture and milk white flesh of his mother's tits. Her nipples were very large, as wide around as a baby's palm, and her rubbery teats protruded with her incestuous excitement. Sharon glanced at his crotch and suppressed a groan as she saw a rigid, absolutely enormous hard-on tenting under the towel.

"Come on, Mark," she cooed. "Don't be shy. Don't you want to rub Mommy’s big tits?"

Mark was too dumbfounded to notice her salacious tone. His trembling hands came down, the fingers digging gently into the spongy softness of his mom's huge tits. Sharon moaned openly as he kneaded and massaged her enormous tits, rolling and squeezing them, her stiff teats poking onto his palms.

"Oh, son, you're very good at that," Sharon purred. "You like it, don't you, baby? It's all right if you do, Mark. You don't have to be embarrassed. It's perfectly natural. You like massaging my big tits don't you?"

Mark obviously couldn't speak. His cock was obviously as hard as stone now, and Sharon could hardly believe how stiffly it throbbed and jerked under the fabric.

"Mark," she said innocently, "Why do you have such a big hard-on? Is this really turning you on so much?"

Mark gasped, his face reddening brightly. Sharon lifted her hand and swiftly undid the knot holding the towel around his waist, letting it drop to the floor. Then it was her turn to gasp as she stared in wonder at her son's enormous prick.

"Oh, Mark! Mark, it's so big!"

His incredibly long, incredibly fat fuck-pole rose straight out of his big balls and cock-fur, throbbing and jerking stiffly in front of him. His cock-knob was big, puffed up to an incredible size by a skin-stretching load of blood. Sharon gasped as she watched his milky cock juice oozing out of his piss-hole, coating his crimson cock-head with a sticky sheen of cum.

"I - - I'm sorry, Mom," Mark sputtered. "I guess I just couldn't help it."

"I had no idea!" Sharon exclaimed. "Rubbing my tits did turn you on, didn't it, honey? Why, I think this is the biggest, stiffest cock I've ever seen in my life!"

Mark continued to look embarrassed until he realized that his mother was now stroking his hard-on, obviously enjoying herself as she slid her fingers lasciviously up and down his prick. His giant cock responded by squirting out more cock-juice onto her palms.

"Oh, my poor, poor baby," Sharon purred. "You're never going to be able to get to sleep with a hard-on like this. Would you like Mommy to give you some relief, honey? Sit up on the edge of the bed for me, will you? Hurry, Mark!"

Mark did as his mother asked, sitting on the edge of the bed with his giant fuck-tool throbbing wildly up in front of his belly. Sharon felt her pussy creaming heavily as she slid off the mattress and knelt before him. It was, she thought, high time for a long session of mother-son cock-sucking.

She wrapped her fingers tightly around the bloated fuck-tool looming in front of her face, again marvelling at its thickness and stiffness. Then the horny, naked mother started pumping her fist rapidly up and down in a skilful hand job. Mark shuddered with pleasure, sticky cum-juice bubbling more heavily out of his piss hole, running onto his mother's hand.

"Does this feel good, baby?" Sharon mewled. She jacked her hand fast, staring at his cock-head, watching the pre-cum ooze out in obscene little squirts. "This is how you do it to yourself when you beat your cock-meat, isn't it? Do you like the way Mommy’s beating your cock meat for you?"

"Yes!" Mark cried. "Oh, yes!"

"Then I'll bet you'd like it even more if Mommy did a little cock-sucking," Sharon said excitedly. "Would you like that, baby? Would you like your own mother to suck off this big, throbbing cock?"

"Yes, yes! Oh, please!"

Sharon slid her cum-slicked fingers to the root of his massive boner, preventing it from throbbing. Then she opened her mouth wide and plunged her lips over his cock. She forced her head down until she was nearly choked herself on his cock with half of it jammed into her gullet. Sharon shut her eyes and locked her lips in a tight, compressed circle around the blue veined stiffness of her son's fuck-meat. Then she started sucking, very hard, bobbing her head and slurping noisily around the tasty stiffness of Mark's cock.

It was delicious, the biggest, stiffest, tastiest cock she'd ever sucked in her life. Sharon had been a little obsessed with cock-sucking during her late teens, and had gone through a period in which she'd tried to coax the cum out of a different set of balls every day. But her son's cock was the biggest and best-tasting of all. Sharon really knew that she would never get her fill of sucking the hot spunk out of her own son's cock.

Mark looked down at her dazedly, beholding the spectacle of his own gorgeous mother with her lips stretched tightly around his cock, hearing her gurgling sounds of cock-sucking pleasure as she shamelessly mouthed his cock-meat. His hands dropped, cupping the back of her head. Then he excitedly began to grind his hips off the bed, fucking his cock down her throat.

"It feels good, Mom!" he moaned. "Harder! Oh, shit, I never thought anything could feel so good! Harder, Mom, suck my cock!"

Joyously the naked mother bobbed her head, excitedly fucking her face with the cum-drooling stiffness of her son's hard-on. She laved his cock-tip continually with her tongue, lapping the jizz out of his piss-hole. Her cheeks reddened as she sucked her son's cock as hard as she could, dragging her lips up and down his fuck meat.

"Harder, harder!" Mark gasped. "Oh, fuck, it's gonna shoot!"

Now the wanton mother could feel the massive cock swelling even stiffer between her lips, beating wildly on the roof of her mouth, signaling that he was about to cum. Desperately she craved the taste of his jism, but suddenly felt seized by a longing that, in a sense, was even more depraved.

I want to watch it shoot out, Sharon thought. I want to watch the first blast shoot out, and then I want to suck out all the rest of his cum.

Sharon's madly-slurping mouth brought her son to the very brink of squirting. Then the horny mom slid her mouth off of his burning cock.

Mark jerked his hips excitedly off the bed, his cock throbbing. Her eyes glowing with feverish hunger, Sharon caught his puffy, drooling cockhead between her fingers. Mark yelped as she pinched it hard, preventing the cum from spewing out of his meat.

"No! Mom, let it shoot! It's killing me!"

"You want to shoot your cum, do you?"

She pinched his cock-head tightly, knowing that to relax the pressure would let the white cum fountain up from his balls. Then she shameless mother wrapped her fingers around his aching, throbbing fuck-pole and started beating his cock-meat again. Her right hand whipped up and down his throbbing, tingling cock-meat, torturing her son, keeping him at the very brink of cumming.

"Does this feel good, Mark?" she asked, her voice shaking with passion. "Do you move your fist this fast when you jack off? Do you, Mark? Mark, what do you think about when you jack off?"

His enormous cock had bloated to a lurid crimson shade now, as if it would explode. Sharon pinched his cock-head tightly and continued to whip her fist faster and faster up and down his hard-on. Mark grimaced, writhing on the bed.

"Let it shoot, Mom! Oh, fuck!"

"You think about fucking your mother when you jack off, don't you?" Sharon panted. "That's right, you think about sucking Mommy’s big, juicy tits and ramming this big cock of yours in and out of Mommy’s cunt. Will you keep your cock hard for me, Mark, if I let it squirt? Will you, baby? Mommy’s cunt is so awfully wet and swollen. No matter how hard you cum now, Mark, I want you to keep your cock nice and stiff for me, so you can fuck my tight, juicy little cunt!"

"Oh, Mom! Oh, Mom, please!"

Sharon finally released his puffy cock-head, simultaneously jacking his cock with her right hand. Mark shuddered as the hot, milky-cum sprayed out of his burning cock.

The blast was incredible, shooting out of his open piss-hole and squirting over her face and enormous tits, coating them with thick lines of jizz. Sharon watched the sticky jism spew out and almost forgot to shove his gushing cock back into her mouth. But she finally remembered, after her wildly pumping fist had made almost half of the geysering cum-load shoot over her. Moaning loudly, the naked mom plunged her lips back over his throbbing, erupting cock. Then she contentedly started swallowing and sucking loudly at the same time, letting the rest of his cock-juice shoot across her tongue, splashing on the roof of her mouth, running down her throat.

Mark held her head, jerking his hips convulsively off the mattress as the cum kept streaming up from his balls. Sharon eagerly gulped it all down, smacking her lips around his spewing cock-shaft as she savored the taste of his cum. Finally she slid her wet mouth off of his cock, her belly feeling warm from all the cum she'd gulped.

"Oh, Mom," Mark groaned. "I swear, I thought you were going to kill me! I never came that hard in my life!"

"I'm sure you didn't, baby. But it looks like you've kept your promise to Mommy, haven't you? You've still got a nice, big hard-on, don't you? Now, Mark, would you like to fuck Mommy's cunt?"

Mark nodded. Being kept on the brink of squirting for so long had made his stiff cock really ache, so that he would have to blow several wads in a row before his prick would even be capable of getting soft. Now the massive organ grew stiffer than ever as his mom rose before him, scooping up his jism off her tits and licking her fingers clean.

"I'm going to lie on my back, Mark, so I can put my legs over your shoulders. Your cock will really go in deep that way."

The naked mom's huge tits quivered firmly as she slid onto her back on the bed, never taking her eyes off of her son's rigid cock. She wiggled her ass into a good humping position, then lifted her legs high in the air. Mark stared at her wide-open, shaved, hairless pussy, seeing how wet and swollen her pink pussy looked, his massive cock throbbing in anticipation as he realized that he was about to bury his giant fuck tool into his own mother's cunt.

"All right, sweetheart. I think it's time to fuck Mommy’s pussy now." Excitedly Sharon wiggled her rounded ass on the bed, her knees hovering over her shoulders. "Hurry, Mark. Can't you see how wet and sticky my pussy is? It's throbbing, lover. It's throbbing because it wants your cock!"

Mark climbed onto the bed, his huge cock twitching as he prepared to mound his naked mother. He crawled into position between her thighs, then moved his hips downward, trying to nudge his puffy cock-head into her cunt. But his cock was throbbing so much that it was hard to center his cock-tip. Sharon reached down, grasping his cock and fitting his spongy cock-tip into her pussy. Then she threw her arms around his shoulders, gasping with intense, incestuous pleasure as she felt his meaty fuck-pole finally beginning to batter its way into her, stretching her tender pussy-hole as inch after inch of her son's hard-on plowed up her tight, juicy cunt.

"Do you - - unh. Do you like that, baby? Does my pussy feel good around your cock?"

Mark answered only with a groan. Never had he dreamed that his own mother's pussy could be so tight and juicy, could cling so deliciously to his huge, throbbing cock. The naked mother started humping to meet his fuck-strokes, her enormous tits quivering as she pumped her tight pussy onto her son's cock.

"That's right, son! Oh, yes, it's so fucking big! Fuck me deep, lover! Ungghh! Oh, Mark, oh, please, fuck that monster all the way in!"

Mark kept shoving his cock up his mom's surprisingly tight pussy, wiggling his hips to help his meaty fuck-pole slide all the way up her cunt. Finally it was stuffed to the balls in her hairless pussy, his cock-knob probing her womb, all the way up his mother's tender, throbbing cunt. For several seconds the youth lay motionless on top of her body, letting his hard-on savor the intense pressure of being sucked and gripped by his mother's cunt. Then, as his mother humped madly beneath him, the horny son let his chest come down on her enormous tits.

"Fuck me, Mark! Fuck me!"

The youth slid his hands down, clutching the sides of her heaving ass-cheeks, nearly making her pass out as his massive hard-on speared another inch up her gooey cunt. Slowly Mark lifted his hips, feeling her tight pussy cling wetly around his cock. He paused with just the tip of his cock inside her, then sighed as he speared it back into her cunt.

"Ungghh! Harder, Mark!" Sharon was so horny that she knew her pussy could start spasming at any moment. Her ankles bounced on her son's shoulders as she heaved her ass frantically off the bed, rhythmically pumping her tight pussy onto his cock. "Fuck me, baby, fuck Mommy’s pussy! Hurry, Mark, fuck me fast, fuck me hard! I need to cum, lover! Mommy needs a good cum!"

Mark started stroking, his mother's huge, stiff-nippled tits quivering under his chest. He pumped his giant cock in and out of her pussy, panting as he felt her glistening cunt-walls sucking exquisitely around his cock-meat. Sharon humped wildly to meet his rhythm, nearly humping her hips completely off the bed as she pistoned her wet, throbbing pussy onto her son's fuck meat.

"Fuck Mommy, fuck Mommy!" she gasped.

Now her tender, clasping cunt had begun to suck and contract round his cock as if it had a will of its own, wetly nursing the thrusting shaft of his hard-on. The top of his mammoth hard-on chafed her clit with every stroke, sending waves of intense pleasure coursing through her body. Her own son was the best pussy fucker she'd ever had between her legs!

Harder and harder Mark fucked his mom's juicy cunt-hole, repeatedly slamming his cock to the hilt in her burning, aching cunt. Then he suddenly quickened his rhythm dramatically, and Sharon knew that he had another load of cock juice welling up in his balls. His huge hard-on pounded up his mother's tight pussy, banging her pelvis onto the sheets, fucking her so fast and hard that she could barely hump her ass fast enough to meet his fuck-strokes.

"Harder, Mark, harder!" She started clawing his back in her excitement, her face red and contorted with incestuous lust, her hips heaving in a blur off the sheets. "Ungghhh! Oh, Mark, oh, fuck, oh, shit, I - - ungghh! Harder, baby, fuck Mommy’s pussy! Cumming now, lover! Shoot your cum again, shoot it up my cunt, Mark! Unghh, unh, unh, oh yes, oh fuck, I'm cumming!"

Her pussy erupted into a series of luscious, drawn-out spasms, her shaved, hairless fuck-slit smacking and contracting juicily around her son's driving cock. Mark kept fucking his cumming mother harder than ever. Finally he collapsed on her heaving tits, plowing his aching cock to the hilt in her gooey cunt.

The second load of cock-sap streamed up from his balls, making his cock spew a frothy cum load deep into his mother's cunt. Sharon felt his hot dick-juice spraying deep inside her pussy. Feverishly she contracted her pussy muscles, making her cock-filled cunt-hole suck the last drops of cock-cream out of his cock-meat.

"Oh, Mom," Mark sighed, panting on her shoulder. "I want to keep fucking you, Mom! I want to fuck your pussy all night!"

"All right, baby," she whimpered, splaying her creamy thighs as wide apart as she could. "Go ahead. Fuck Mommy’s cunt again!"

Mark began plowing his huge cock all the way up her pussy again. Sharon shuddered and wrapped her legs tightly around him, high across his back. Mark started pumping, driving his cock into her. It wasn't long before they were both humping as fast as they could.

CHAPTER FOUR

"Ungghh! Shit, Mom!" Mark gasped. "Come on, you gotta let me go to college some time, don't you? Ungghh! Oh, shit, you sure do love sucking my cock!"

It was the next morning, and the fucking twosome had already been awake for an hour. Sharon had already coaxed one load of cock juice out of her son's balls, and now, with breakfast behind them, she was anxiously trying to suck out a second.

Mark was overdue at college, but she didn't care. They were both naked, Mark sprawled on the living room couch with his ass pushed to the edge of the cushion, gasping as he watched his horny, huge-titted mother slurping noisily on his cock. The youth's giant fuck-tool was swollen as if he'd never shot a cum-load at all.

Sharon's eyes were tightly shut, blocking out all thoughts that didn't immediately relate to the taste, feel and stiffness of her son's hard-on. Her right hand was wrapped tightly around his cock-shaft, lewdly gripping and squeezing. Her brown-haired head bobbed rhythmically on his cock as she fucked her mouth with his cock.

"Ungghh! Oh, fuck, Mom, you really work out on it!" Mark gasped. "The first thing I saw when I woke up was you with my cock in your mouth! Ungghh! Oh, Mom, keep sucking it! You're gonna make me cum!"

The naked mother puckered her cheeks sharply, increasing the suctioning pressure around her son's cock. Her head moved in a blur now, bucking on her son's crotch, fucking his ironhard cock in and out of her mouth. She tightened her fingers around his cock and started whipping her hand up and down as fast as she could, desperately trying to coax the morning's second load of cock-cream up from his balls.

"Any second, Mom! Any fucking second!" He pulled her hair, his spongy cock-head pulsing angrily on the roof of her mouth, signaling that he was about to spew out a huge load of cock-juice. The cock-loving mother kept sucking and jacking his tasty hard-on as hard as she could.

A giant wad of thick, salty cum-cream spewed out of his cock, spurting on the roof of his mother's mouth and then gushing down her throat. Sharon started swallowing hungrily, pumping his prick with her fist, desperate to bring up every drop. Repeatedly his delicious cum squirted out of his cock-knob, until his balls had no more cum-cream stored up to give her, until the mother's belly was finally full of cum.

“Mmmm, Mark! That was really a good one!" Sharon giggled as she finally let his big cock pop out of her mouth, gulping down the last of his cum-juice. Her smile became mischievous as she realised what she wanted next.

"Mark, darling, would you like to learn about playing with Mommy’s asshole?"

Mark's cock answered for him, throbbing more stiffly than ever, dripping a lurid mixture of saliva and cum. Sharon could feel both her pussy and asshole pulsing now, as she realized that she was about to initiate her son into the forbidden act of ass-fucking. She got on the living room carpet on her hands and knees. She turned so that her ass faced him. Then she reached up and spread her ass-globes with her fingers. Mark groaned at the sight of her asshole.

"Oh, fuck," Mark sighed.

"Get down here with me, baby," Sharon purred. "Mommy wants you to do some asshole licking now, honey. Come on, Mark, get that nice tongue of yours in Mommy’s ass."

Sharon had thought that her son might be reluctant to lick her asshole. Instead he surprised her with his eagerness. First he just explored her asshole with his fingers, making her shudder as he wormed his middle finger into the puckered ring, exploring the rubbery interior of her ass. Then he applied his tongue and lips. Sharon squealed as her son started licking her asshole, swiping his tongue back and forth across her puckered pink asshole, sending waves of pleasure shooting through her body. Sharon thrust her hand under her belly, shamelessly finger-fucking her dripping cunt. Suddenly she realized where she wanted to feel her son's gigantic cock-shaft pounding next.

"Mark, you want - - unh! You want to fuck Mommy’s asshole now, don't you?" she panted. "That's what you want, isn't it, son? You want to shove that big, stiff, fucking cock of yours right up Mommy’s ass!"

"Y-y-yes," Mark stammered. His face was red and his cock was very hard. "Yeah, I really do."

"All right, baby. Mommy will let you then. Mommy will let you shove that big, hard cock up my asshole, and shoot out all your hot cum. But Mark, first you have to do something to lube me up. My asshole's just too little to take that giant cock of yours without some lubrication. There's some Vaseline in the bathroom. Would you be a dear and get it for me Mark? Then you can fuck Mommy’s asshole as hard as you want!"

Mark practically ran into the bathroom, his naked body shining in the curly morning sunlight, his enormous fuck pole throbbing stiffly before him. Sharon gasped her ass-cheeks and spread them even wider, eagerly opening her asshole completely for the for the coming invasion of her son's cock.

"Hurry, Mark!" Sharon panted, as she saw him return. "Hurry, baby, lube up Mommy’s asshole! Mommy needs your big fucking cock up her ass!"

Mark knelt on the floor, beside his stacked, horny mother, uncapping the jar of petroleum jelly. First he smeared the yellowish goo liberally all over his cock. Then he took out another glob, and Sharon gasped as he pasted it on her asshole. Mark wormed first one, then two fingers up her narrow, clasping asshole, basting the inside of her asshole until the rubbery sheath was hot, gooey, stretched and ready for his prick.

"Okay, Mark, that's enough!" Sharon squealed. "Now fuck Mommy’s asshole, baby! Please, my asshole's so fucking horny! Put your big cock in, son, fuck Mommy’s ass!"

Mark mounted his fuck-starved mother, aiming his swollen cock-head at the invitingly distended ring of her asshole. Sharon shuddered with pleasure as his massive cock started to push into her, instantly stretching her asshole to the bursting point around the invading thickness of his cock.

"Oh, fuck, it's so tight!" Mark moaned. He winced with pleasure, feeling his mom's rubbery asshole sucking and contracting around his cock. Sprawled top of her, he started to hump his ass, fucking his huge cock into the welcoming tightness of his mother's asshole.

A shameless smile of intense sexual pleasure curled Sharon's lips as she felt his meaty hard-on plowing up her ass, filling her hole.

"Deeper, Mark!" she pleaded, as she torridly started humping beneath him. Her asshole sucked and spasmed uncontrollably, nursing the driving stiffness of her son's huge prick. She’d loved getting ass-fucked by her late husband but being fucked up the ass by her son was so much better.

Mark could hardly believe what a tight, hot little asshole his mother had. The harder he pushed his cock into her ass, the more lusciously her ravished asshole seemed to suck around his prick.

Finally his cock was embedded to the hilt, and his mother's asshole was clamped around the root of his cock. The mother thrust her hand under her belly and started finger-fucking again, her fingers darting rapidly in and out of her pussy. Mark started reaming out his mom's juicy asshole, pumping his huge cock through the rubbery grip of her asshole.

"Ass-fuck me!" Sharon pleaded. "Harder, Mark! Unh, don't worry about hurting me! Oh fuck, oh, shit, your big cock feels so good! Go ahead and fuck Mommy’s horny little asshole, baby! Unggh, unh, unh, fuck your cock up my ass!"

Mark picked up the pace of his asshole reaming, panting as he drilled his freshly cum-laden cock between his mom's jiggling ass-cheeks. In and out his giant cock sawed, rooting into the innermost depths of his mom's ass. Sharon finger fucked as fast as she could, already feeling herself drawing close to a cum.

"I said fuck my asshole, Mark!" she cried, almost shouting out her need to have her asshole reamed by her son's gigantic cock. "Harder, Mark, harder! Fuck Mommy’s asshole! Ahhhh, yes, Mommy’s asshole loves your huge prick!"

Panting loudly, Mark started fucking his mother's asshole as hard as he could, making her ass-cheeks jiggle. Sharon finger-fucked madly, her face red and contorted with the ecstasy of sodomy. Finally she felt herself cumming, her rubbery asshole sucking and contracting uncontrollably around the pounding stiffness of Mark's big prick.

"Fuck my asshole, fuck my asshole!" she gasped. "I'm cumming, Mark! Ungggghhh, unggghhh, oh, shit, oh, fuck! Fuck Mommy’s asshole, I'm cumming!"

Then the morning's third load of cock-juice spewed up from his balls, gushing in a torrent deep into his mother's ass. Sharon whimpered in ecstasy as she felt his milky cum spraying into her ravished asshole. Wantonly she flexed her muscles around his cum-shooting cock, helping her son shoot all of his jizz into her asshole.

A moment later as they lay still, Mark’s cock buried deep in her asshole, the phone rang. Mark sighed as he pulled his cock out of his mom's asshole. Sharon giggled as she went for the phone, still feeling the lurid mixture of Vaseline and spunk squishing between her ass-cheeks as she moved. Her expression was one of pleasant mystification when she returned to the living room five minutes later.

"Mark, you'll never believe who that was."

"Who?"

"It was my friend Emily. You remember her. The one with the big - -” Sharon's words trailed off into a giggle as she gestured at her own huge tits. "Well, I haven't talked with her far ages, and now, believe it or not, Emily wants to swap sons with me! She wants you to stay at her house for a week while Adam stays with me."

"What?"

"It used to be my idea, believe it or not," Sharon elaborated. "I once told her that I thought it was a good thing to do if one of us were having trouble with our sons. I mean, just to give the teen a new environment for a while. And now, I guess Emily's decided to take me up on it! I don't know why! She won't tell me what the trouble is with Adam."

"Well, you're going to tell her to fuck off, aren't you?" Mark insisted. He winced, stroking his cock. "I mean, who's going to take care of my cock if I go live with her for a week?"

"Maybe she will, baby," Sharon giggled. She knelt beside her son, already staring hungrily at his cock. "And maybe I'll wind up taking care of Adam. I don't know. But something's telling me to say yes."

Mark opened his mouth to protest, but Sharon silenced him by wrapping her fingers around his cock. Then she started jacking his enormous fuck-pole as fast as she could, staring at the Vaseline-smeared, cum-oozing crown of his cock-meat.

"Mark, I think I'm going to give you a note to take to college today," she purred. "It's going to let you miss your last period class every day for a week. That way you can come home every afternoon before Adam does, and give me a nice, hard fucking for the week Adam stays with me. Would that all right, lover?"

"But I want to keep fucking you, Mom!"

"And you will, baby. Every afternoon, all week. But you might just wind up fucking Emily as well. As I said, lover, something's just telling me to say yes!"

Mark seemed confused, but then he forgot everything except his throbbing cock. His mother's pumping fist had made it as stiff as if he'd never cum at all. Sharon licked her lips, staring down at his fuck-meat.

"Mommy loves your cock, son," Sharon whispered. She curled up on her side next to his hips, sliding her hand to the root of his cock. Then she opened her mouth and plunged his sticky, dripping cock down her throat, wrapping her lips wetly around it, sucking her son's big cock as hard as she possibly could.
