"Let me do it now, Eddie," Roy begged.

"Okay, kid," Eddie sighed, "I guess that's only fair."

They changed placed, and Joan felt her younger son's hot hands closer over her tits. He was a little more awkward than Eddie, but just as eager. She bit her lip and smothered her little cries of pleasure as he fondled, licked and sucked her swollen tits. Soon, Joan didn't think she could take much more stimulation without losing control of herself, but the kids showed no sign of stopping. In fact they were just getting started.

"My turn now," Mindy told Roy when he'd finished sucking Joan's lust-engorged nipples.

Mindy got around in front of her mother and started easing off her dress. Joan used all her strength to try to break free, but the boys held her down. Next came her panties. She whimpered in protest, then blushed furiously, as Mindy whisked off the lacy garment and tossed it aside. The kids studied their mother's slim, sexy body.

"Oh, wow," Mindy breathed enviously.

She wished she had her mother's big full breasts, lush dark bush, and curvy rounded hips. Eddie and Roy were wide-eyed with lust. Joan was practically dying with embarrassment, but there was nothing she could do but lie there and take it. She just hoped she could keep her lust hidden till the kids had gotten tired of playing with her. She stiffened as Mindy started pushing her legs apart.

"Mindy, no," she snapped, "absolutely not."

"Aw, come on, Mom," Mindy smiled, "have some fun for a change."

That really hit home with Joan. When did she and Ben ever have fun? It was as if they'd been raised not to believe in it. Even their sex was no fun. It was grim, guilty, and hurried, but it wasn't fun. Joan hadn't realized what fun sex could be till she'd spied on her own children.

Mindy pushed her legs wide open, revealing the moist rosy flesh of her pussy and the fringe of brown curls. She went right for Joan's clit, grasping it between her thumb and forefinger, kneading it. Joan just managed to smother the lusty whimper that rose to her lips. It felt marvelous to have her clit rubbed and rolled like that... even by her own daughter!

"Admit it, Mom," Mindy leered. "you love it!"

Joan shook her head violently, but Mindy knew she was lying. She could feel the hot, sticky cream drooling from her mother's cunt, and she knew no woman could hide that obvious sign of arousal. Mindy rubbed her mother's throbbing joy button faster, and more thick hot pussy-cream soaked her fingers. She'd succeeded in turning her mother on, and now all she had to do was get her to admit it.

"Eddie, go down on her," she instructed.

"Hey, all right," Eddie cried.

Mindy scooted out of his way, and crawled between his mother's legs, lowering his face right down into to her glistening, pink pussy-slit. Joan knew this was going to be the supreme test of her self-control. When she'd watched the kids through the keyhole, the thing that had excited her most was the pussy-eating. Deep down, she knew she'd adore to have that done to her. Well, now it was going to happen, only she didn't dare admit her enjoyment.

"Uuuuuunnnhhhh," she gasped.

Suddenly Eddie was raking his big hot tongue up and down over the swollen flesh of her gaping slit, giving Joan the most exquisite sensations she'd ever known. She felt her whole body flushing with arousal, and her face twisted into a horny grimace. She managed to keep quiet, but that was about all. To her humiliation, she creamed right into her son's mouth.

"Yeah, Mom," he chuckled, "you love that, don't you? Mmmmmmm, you taste good, too! I'm gonna lick your pussy till you come!"

Joan moaned hoarsely, knowing she wouldn't be able to keep quiet if he did that. It was enough of a struggle right now. Her son was dragging his long, stiff tongue through her juicy slit, and it felt marvelous. Then he zeroed in on the most sensitive spot of all, the erect and pulsing bud of her clit, already hotly stimulated by Mindy's skillful fingers.

As Eddie's tongue touched her throbbing clit, Joan almost flew off the bed. He used the stiffened tip of his tongue to flick and lash the ultra-sensitive bud, and it was the most wonderful feeling she'd ever known. Her cunt drooled helplessly, the musky liquid soaking his bobbing chin. Despite her embarrassment and guilt, Joan knew she was doomed. She wanted this incredible pleasure to go on and on... she wanted her own son to suck her cunt!

"Go with it, Mom," Mindy urged from behind her, "you know you love it."

"Nooooooo," Joan murmured.

But the husky excitement in her voice told the kids she was lying. Mindy knew her mother was on the point of losing all self-control. Eddie was very close to pushing his normally stern and puritanical mother over the edge into a mind-blowing orgasm!

Mindy watched intently, because everything depended on her brother's efforts. He was an expert pussy eater, as their mother was finding out. Mindy hoped he was so good, she'd soon be begging for more.

Eddie's glistening tongue was lashing up and down over Joan's incredibly-aroused little joy button, sending blast after blast of delicious pleasure through her naked, writhing loins. The sensations were so intense, she had her teeth clenched, struggling not to cry out. But Eddie seemed to sense his mother's resistance. It was time to hot up the tongue action a bit.

"Ohhhhh, God, unnnhhhhh," Moan gasped.

Eddie had made his tongue long and stiff, and he was sliding it up her cunt. The sensation was exquisite. It was more than Joan could take. She began to whimper lustily as her son probed deep into her cunt with the pointy tip of his tongue. Her husband had never gone down on her in all their married life, and she just wasn't prepared for the incredible pleasure she was feeling right now. The last of her mental defences simply melted away.

"Ohhhhh, yessss," she whimpered, "Lick me! Poke your tongue inside my pussy, honey... all of it... uuuuuuuhhh, don't stop!"

Eddie glanced up at Mindy and saw that she was grinning broadly. They'd won! Mom had admitted her pleasure, and now she wouldn't dare tell their Dad what they'd been up to. She couldn't, because she was part of it now. Her pretty face twisted into lusty contortions as Eddie began to tongue-fuck his beautiful mother in earnest. He pistoned the stiff meat hard and deep in her famished slot, and she wailed with delight.

"Unnnnnhhh, God, yes," she moaned, "do it to me, baby! Lick Mommy's cunt! Make me come... oooooohh, I need it so bad!"

Mindy felt all the tension leaving her body. It had been a bit scary there at first, but now that they'd 'persuaded' Mom into joining their family fun, they were safe... or so she thought. None of them had the faintest idea that at that very moment, their father was about to make an entrance of his own.

Ben Masters had planned a big surprise for his family that Friday afternoon. He'd just gotten a promotion and a raise, and he intended to celebrate by taking them all out for a fancy dinner. His boss had allowed him to leave work early, giving him the rest of the day off to celebrate with his family. Ben entered the house humming happily to himself.

He could hardly wait to tell Joan and the kids the good news. But to his surprise, there didn't seem to be anybody around. Down-stairs was empty. Where the hell could everybody be?

Ben suddenly heard faint, muffled sounds coming from upstairs, so he went up to investigate. There were sounds, all right, really strange ones, and they were coming from the master bedroom. It sounded like a woman moaning in pain!

Alarmed, Ben went silently to the door, knelt and peered through the keyhole. Later he figured it was as close as he'd ever come to having a heart attack. His eyes took in clearly what was happening on the king-size bed, but his mind refused to believe what he saw! It looked exactly as if Joan and their three kids were having a sex orgy.

"Ridiculous," Ben muttered, rubbing his eyes.

He must have been working too hard lately to have a fantasy like that. He looked again, but saw exactly the same thing as before. His whole family was naked on the bed, and Eddie was going down on Joan while Mindy and Roy watched. This time Ben couldn't deny the evidence of his own eyes. But his mind still reeled in shock at what he saw.

"Ooooooh, Eddie, honey, do it harder now," Joan cried, her face contorted with pleasure, "get me off, baby. Fuck mommy with your big, fat tongue!"

Ben felt his cock start to stiffen. Shocked and stunned as he was, he couldn't help being turned on by his wife's obvious horniness. He'd never known Joan to be this aroused, at least not since the first week of their courtship, before their parents had forced them to clean up their act. But so often during their marriage he'd longed for Joan to act like this.

Secretly he'd wanted to make love with the lights on, to see his wife's gorgeous, naked body, to watch her face twist in hot pleasure as he fucked her. He'd wanted to go down on her, too, and he ached to have her suck his cock. But he and Joan had always been so moralistic and puritanical, he figured there was no point in asking her to do such perverted things.

Now he saw how wrong he'd been. Joan was just as hungry for excitement and novelty as he was. She was so eager for it, in fact, that she was getting it on with their kids! She was going out of her mind with pleasure as Eddie pistoned his long stiff tongue in her famished little fuck hole.

"Oooooo, God! I'm almost there!" she sobbed.

Joan arched her body to take her son's pistoning tongue as deep as she could get it in her slippery-wet pussy-slit. She twisted her fingers in his hair and pulled on the back of his head, pressing his handsome young face into her hairy hole. Her eyes were tightly closed, shutting out everything but the wild pleasure she was experiencing as her own son tongue-fucked her to climax.

Ben's cock went stiff as steel, straining against the confinement of his pants as he watched his eldest son give his wife the tongue-lashing of her life. He could tell she was very close to orgasm by the look of total lust on her flushed face and the loud squeals of ecstasy that escaped from her hotly-parted lips.

"Unnnhhhh, baby, I'm coming!" Joan screamed. "UHHHHHHH!! JEEEESSSUS, YESSSS! AHHHHHGGGGGHHHHH!"

Ben damned near came, too, as he watched his beautiful wife climax noisily. He'd never made her come like that. But then he'd never done the deliciously depraved things to her that their son just had. He'd never crammed her creamy pussy full of his tongue, even though he'd often fantasized about it. Well, things were going to change, starting this very day. Their sex life wasn't going to be boring and guilt-ridden any more.

"Uhhh! Uuhhhh! UUUUUUHHHH! FUCK! I'm coming so good!" Joan wailed.

Eddie drew back and watched the results of his work, grinning broadly. He had good reason to be proud of himself. His pretty mom was coming like crazy, her body violently wracked by the most powerful orgasmic spasms she'd ever known. His big cock was stiff and ready, and he hungrily eyed the come-spurting mouth of her gorgeous cunt. Mindy saw the familiar look of lust on her brother's face and read his mind easily.

"Go for it, Eddie! Fuck her," she urged.

"Hey, what about me?" Roy protested, fisting his rock-hard cock. "I wanna fuck her, too."

"You'll get your turn, Roy," Mindy assured him.

Ben listened to all this and turned red. He'd been so pre-occupied with watching Joan, he'd lost sight of what was really going on here. This was incest! He couldn't allow this sort of thing to go on in his house. He and Joan were definitely going to have a better sex life, but it was not going to include the kids... no way in the world! He had to stop this perversion before things got out of hand.

But he didn't act fast enough. Eddie flipped his mother over into the doggy position and shoved his cock into her juice-filled cunt before Ben had even opened the door. Joan clawed the bedspread and let out a hoarse sustained moan of ecstasy as she took her son's rock-hard cock to the balls. It filled her to the brim, pulsing and throbbing inside her tightly-stretched pussy like a fire-hose.

Lustily, Eddie began thrust his huge cock into his mother's hot, clinging cunt again and again, fucking her deeply. His rapid, energetic strokes left her breathless.

"Unnnhhhh, shit, yes, baby," Joan panted, "fuck me good and hard."

Ben was torn between shock and lust. He was stunned to his wife and son fucking, yet he was hotly aroused by Joan's wanton display of animalistic lust. She was reacting the way he'd always wanted her to... thrusting her hips back like a whore... begging for more cock... squealing out her lust. Except it wasn't him his wife was being so sexually uninhibited with... it was his son!

As Ben watched, Eddie began to fuck his mother with fast, urgent strokes that rocked her slim body and made her big tits jiggle beneath her sensually. Joan was whimpering with pleasure. Eddie's cock was slamming into her upraised cunt so hard and fast, her copious cunt juices were being whipped into a creamy froth. Her big, firm tits swung heavily back and forth, jiggling lewdly with every powerful thrust. His beautiful wife was more insanely aroused than Ben had ever seen her.

"Fuck it to me, fuck it to me!" she babbled. "Uuuhhhh, yeahhhh! Fuck mommy good, baby!

Ben's cock was as hard as a rock, jerking and twitching against his fly as he watched his son's long, glistening prick slam repeatedly into his wife's shamelessly-upthrust cunt... He recalled that first delicious week of his courtship with Joan, the only time they'd made love without guilt and inhibitions.

They'd been innocent young people then, hungry for each other, not aware that sex should be curbed. If only they'd continued like that! But they'd allowed themselves to be ruled by their parents' ridiculous puritanical teachings. Now Joan had gone back to her old self, the way she really was... lusty and eager and hotblooded.

Eddie's deep, hard fucking brought his mother quickly to the verge of orgasm. Joan closed her eyes and sailed into orbit, the powerful pleasure-spasms wracking her body. Ben wished he could make her come like that... maybe he could!

"Unnnhhhh, yes, I'm cumming!" she wailed. "Ohhhhh, Eddie honey, fuck me hard! Uhhhhh, God, it's so damned good!"

"Unnnngghhhhhhh! Yeahhhh! I'm cumming too, Mom!" Eddie yelled, jetting his load into his mother's visibly-spasming twat. "I'm cumming in your hot, fucking cunt! UHHHHGGGGHHHHH! MOMMMMM!!"

Ben shivered with lust and envy as he watched his eldest son shudder and bury his cock deep up inside his mother, flooding her cunt with his incestuous sperm. Ben's cock felt ready to explode. He was desperate for relief and Joan's recently-fucked cunt looked so tempting. But just as he was about to enter the room and take his rightful place between his wife's wide-spread thighs, Eddie flopped back with a satisfied sigh. Roy immediately took his place, shouting, "My turn now!"

"Unnnhhhh, yesssss!" Joan hissed, as her younger son rolled her onto her back and scrambled eagerly between her glistening thighs.

Roy positioned the head of his cock in his mother's gaping hole and slammed it home with a grunt.

"Uhhhhhh! Fuck, you're tight, Mom!", he groaned, starting to hump his slim young hips madly. Joan hardly heard him. She was in seventh heaven.

Eddie's fucking had felt so great, she wanted more of it. Roy gave her the same hard urgent strokes, blast after blast of hot sensation. Even though she'd just climaxed violently, she was ready to come again within seconds. She just wished that Ben would fuck her like this, hotly and hungrily, without any sense of shame or guilt.

"Ooooh, baby, yes," she panted, "fuck me good and hard, Roy, as hard as you want! Give it to me, son!"

Roy stared down at his mother's big jiggling tits as he fucked her. Each rough thrust of his cock made her howl with delight, a slippery mixture of sperm and pussy-juice bubbling out around his deeply-driving prick. He gave a cry of excitement as he realized his mother's cunt was filled with his brother's jizz, and he was fucking it out of her! Roy stepped up his fuck-thrusts and really pummelled her, slamming his stiff young cock balls-deep into her upthrust cunt. Joan screamed with pleasure.

Ben saw that his horny wife was going to come again, quickly and violently, and he gritted his teeth in frustration. He needed her juicy hot cunt right now, but it was already occupied. Well, he wouldn't miss his chance this time. The moment Roy finished with her, he was going to charge in there and claim his wife for himself. He'd tell the kids the fun was over and to get their asses out of the master bedroom. He wasn't quite sure how he was going to punish them for their incestuous behavior, but he'd figure that out later. Right now all that mattered was getting some relief for his insane lust.

"Ohhhhh, fuck me, Roy honey, fuck me hard! You're making me come!" Joan wailed."Ohhh, God, yessss! I'm cumming again! Unnnnnggggghhhh!"

"Come on my cock, Mom! Cum! CUMMM! ", Roy bellowed, squeezing his her big, jiggling tits with both hands. Then his own orgasm was upon him and he shuddered and stiffened arching his back as his young seed spurted deep up into his mother's spasming cunthole.

He was still hammering his load into her when the bedroom door opened with a crash. Everybody stared in that direction, and then everybody groaned. It was Ben, and he looked mad as hell. He came charging across the room and stood at the foot of the bed, hands on hips, glaring. Nobody dared say a word.

"All right." he thundered, "this little party is over. I want all you kids to get out and go to your rooms until I figure out what to do about your disgusting behavior!"

"Oh, yeah, Daddy?" Mindy said with a mischievous little grin. "If it's so disgusting, how come you've got a hard-on?"

Everybody stared at his sharply tented fly, and Ben turned lobster red. Then everybody started laughing. Even Joan cracked up. It was so obvious that Ben had been spying on them and getting turned on. He stood there looking sheepish and wondering what to do now.

"Well," he said weakly, "it is incest, you know, and that's not right."

"Maybe, Dad," Eddie laughed, "but I sure bet you'd like to get in on it."

"Yes, dear," Joan leered, "be honest with us. While you were watching, didn't you want to join us?"

Ben just went on looking uncomfortable. He hadn't lost all his inhibitions yet, and as horny as he felt, he still couldn't admit it. The family saw that they were going to have to do a little work on him. Daddy wasn't completely won over to their way of thinking yet. But that bulging crotch of his suggested that their task wouldn't be too hard.

"Mindy, honey," Joan said with a knowing smile, "I'm sure you can handle this."

"Oh, wow, can I ever," Mindy said eagerly.

She'd always found her father sexy, and now she had a chance to show him just how she felt. She slid off the bed and walked over to him, and Ben's eyes ran helplessly up and down her cute, curvy, naked body. Grinning enticingly, she unbuttoned his work shirt and helped him out of it. He seemed helplessly in her power as she tugged off his t-shirt. Then she reached for the fly of his pants, unzipping it deftly.

His pants puddled around his ankles, and he stood there in just his jockey shorts, the fly bulging obscenely. Mindy's hands were quivering with excitement as she seized the shorts and tugged them down. She had to go to her knees to do it, and his huge cock snapped free, brushing her face and leaving hot sticky juice. Mindy looked up at her father's big, stiff prick and moaned with excitement.

"Oh, God, Daddy... it's huge," she breathed.

Roy and Eddie just looked awestruck and envious. The old man was hung like a bull, and Mindy could hardly contain herself as she reached for his massive cock and started pumping it in both fists. Ben shivered lustily as his daughter's fingers closed around the rigid shaft. His nostrils flared, and his eyes got glazed with horniness as she ran her hot little fists up and down his engorged prick.

"Come over to the bed, Daddy," she purred, "Let's get comfortable."

Even with his naked young daughter jerking on his cock, Ben still wasn't completely comfortable with all this, and he glanced uneasily at his wife as Mindy pulled him onto the bed.

"You sure this is okay with you. honey?" he asked.

Joan grinned at him wantonly. He'd never seen such a lustful look on her face in all the years of their marriage.

"Ooooh, yes, darling, it's fine with me," she cooed, taking both her sons' cocks in her hands. "I intend to have some more fun with the boys, so there's no reason why you and Mindy shouldn't enjoy yourselves. After all, we're all family aren't we?."

"Yeah! Come on, Daddy," Mindy said impatiently, "let's get it on."

"Get it on?" Ben said dazedly. "Just what does that mean, young lady?"

"Everything, Daddy, " she giggled, reaching for his massive hard cock.

Ben knew he was making a very slow entry into the twentieth century, but he just couldn't help it. It was the way he'd been raised.

"Uh, I just don't think it would be right for us to do everything, sugar," he said.

Mindy wasn't fazed one little bit. Her father just need a little more friendly 'persuasion', that's all.

"Alright, Daddy," she smiled, "How 'bout I just suck your big beautiful cock for now, okay?"

Joan could barely keep from giggling, Ben looked so stunned. Mindy pushed him down onto his back, and his huge rock-hard cock stood straight up... stiff and bulging with blue veins... drooling pre-cum. Mindy knelt beside him, crouched low, and stuck out her tongue, whipping the glistening hot flesh up and down the long granite column of her father's cock. It was to much for Ben.

"Ohhhhhhhhhhh, Christ," he groaned.

Maybe it wasn't right, but he just couldn't resist. He'd never had his cock licked before, though he'd been fantasizing about it for years. He'd always wanted a woman to go down on him, though he'd never dreamed it would be his own sexy teenage daughter. Eagerly Mindy whipped her slick hot tongue all over his prick, coating it with her glistening saliva. Ben slumped back in bliss, unable to resist any longer.

Joan nodded her approval of her daughter's efforts. Mindy had her father completely under control, and in another minute or so he was going to be completely won over. No need to worry any more about him. Joan could turn her attention to her own pleasure. She was lying between her two sons, fisting a nice hard adolescent cock in each fist.

"I'm so glad you boys aren't tired," she purred.

"Oh, we're not a bit tired, Mom," Roy assured her.

"Right! We're just getting started," Eddie grinned.

Both boys were wildly aroused by their sexy, naked mother. Her ripe, mature body drove them crazy with lust. Now she was stroking their cocks, running her hot little fists up and down the rock-hard columns, bringing the brothers to a fever pitch of need. Joan felt hot, sticky cock-juice wetting her fingers, and she shivered with excitement.

It was wonderful to know that she now had three big, stiff pricks to please her. Often after she and Ben fucked, she still didn't feel satisfied, and no wonder. Those quick guilty fucks didn't do much for her. But tonight she could absolutely glut herself on pleasure, fucking one son after the other. For the first time in her life she'd get all the hot, horny fucking she craved.

And Ben was going to get all of the things she'd been too inhibited to give him. He was going to get all his secret desires satisfied by their horny little daughter. Joan was glad for him. She didn't feel at all envious or possessive as she watched him getting his pleasure from another female. And she wasn't shocked because that female was their own daughter. No, for the first time in their marriage, their sex life seemed to be improving. Hell, it wasn't just improving, it promised to be fantastic!
