Having discovered the joy of fucking Mary, Dean was eager to get into Sharon's twat. He was even more eager to strip his beautiful older sister naked, fondle her firm young body and stick his tool into her pussy.
All this came out in the course of a family conference later that evening, when all of them were fully clothed again.
Adam and the girls told how excited they had been while watching the exciting performance; then it was Mary's turn to tell of how thrilling the seduction of the boy had been, how she especially enjoyed the way he had tongued her crack and her bung, promising him she would teach him exciting variations of that game.
The girls had been excited by that act, too, and had agreed that it would be exciting to take Dean to a room and have him lick both their asses.
"There's something we have to make clear right from the start," Adam told the group. "Dean, you can count on getting all the fucking you want from now on, but Mary's cunt is the only one you're allowed to get into."
"Why, Dad?" the boy asked, obviously disappointed.
"Because Mary is fixed up so that she can't become pregnant. The same doesn't apply to Sharon and Emily."
"But you fuck them, don't you?" Dean asked.
"Yes, I do, but I wear a rubber when I do. You see, your cock isn't big enough yet to wear a rubber safely. What you must remember is that just one drop of your sperm getting into a pussy could knock a girl up. I want the three of you to keep that in mind each time you play and get horny."
"Then I can play with the girls and see them bare naked and feel them up and all that?" Dean asked.
"Yes, of course. In fact, there's also a way you can fuck them."
"You mean up the ass, Daddy?" Emily asked, and she wondered how it would feel to take a hard prick up her shitter.
"That's right. Lots of people, men and women, like being ass-fucked. I think it'll be especially good with Dean, because his cock is nice and slim. We could have a little demonstration of ass-fucking later. Are all of you interested?"
The girls and Dean assured him they were, and they agreed that they would give it a try later, after Dean had recovered his vitality.
Leaving the others to chat, Adam went to the well-stocked bar and poured a couple of drinks. He returned with them and guessed that things would soon warm up as he noticed that the three females had raised the hems of their dresses, and that Dean was trying to look at all six thighs at the same time.
The evening wore on pleasantly, and Adam saw that the others were eager to move beyond the stage of conversation and get into action. More than anyone, Sharon and Emily made that clear as they sat together on a couch, Sharon with a hand between Emily's thighs, Emily with a probing hand inside the younger girl's blouse, fondling her firm young tits.
"Since you two seem so interested in playing," Adam told the girls, "perhaps you should put on a little show for us. Who knows, it might help Dean get a hard-on and then we could have a real orgy."
"How about your cock, Daddy?" Emily asked. "Is it hard?"
"It's very hard," he assured her as he watched her playing in Sharon's crotch while she showed him how her pale-blue nylon panties snugged against her warm pussy.
With help from Mary, Adam quickly rearranged the furniture, so the second couch was facing the one on which the two girls sat. Before sitting, Mary drew the hem of her dress above her hips; then Adam was seated to her right and Dean to her left as they watched the two girls petting on their couch, sharing hot kisses, each fondling the body and thighs of the other. While they watched, Adam and his son fondled Mary's thighs and the crotch of her panties; then she gave the boy permission to unbutton the top of her dress, and there was even more for them to play with.
On the couch, the girls removed each other's clothes gradually, unhurriedly, until Sharon took Emily's panties off. Then they were both naked.
While their audience watched intently, they went wild with passion, sucking and fondling tits, stroking warm little pussies until they agreed that it we time to produce some comes. Seconds later, they moved into an end-to-end embrace. For the first time in his life, Dean saw two females lapping cunt in the sixty-nine pose.
It was so thrilling to the boy that he couldn't just watch. He left the couch and went to play with the two writhing, naked bodies, stealing all the feels he wanted, his cock so hard that he couldn't believe it possible.
Mary didn't mind when Dean left her, especially when Adam put an arm around her and fondled one boob with a gentle hand while his other hand rubbed so excitingly in her crotch that her panties became nicely moist there.
There was a wild flurry on the couch as the two girls climaxed at the same time. In his arousal, Dean clutched at both cheeks of Emily's ass. His fingers dug into the firm flesh hard enough to make marks on her sensitive skin, but she didn't seem to mind as the girls untangled and she got up smiling, looking very pleased with herself and her partner.
When Adam began undressing, Mary and Dean followed his example. As Mary began to push her panties down, Dean begged to be allowed to do that for her, and she smiled as she tugged them back up and waited for him.
"Your daddy made the crotch of my panties wet with pussy juice, Dean," she told the naked boy as he crouched before her. "Why don't you make my panties a little wetter with your mouth, darling? I love having the crotch of my panties sucked."
It was all the invitation the boy needed as he dropped to his knees, and ran his hands up her thighs. Then his upturned face went to her crotch. While the others watched intently, Dean sucked greedily.
He mouthed and sucked and licked so excitingly that Mary realized that she was on the verge of coming. As the first shock wave struck, she clutched at his head and pulled it tightly against her, her hot crotch jerking against his face until the waves had all pawed.
The girls were impressed, and then they watched as Dean slowly pulled Mary's wet panties down, taking his time about it. When her panties had been pulled to just below her ass, Dean began kissing the plump, smooth cheeks, but she told him to hurry and strip her because she had a surprise for him, one that he would like very much.
Seconds later, Mary stepped out of her panties and knelt on the couch with her head down and her big butt arched high, her asshole and cunt clearly displayed for all to see.
"Adam darling," she said with a sigh, "since Dean likes asses so much, I have a feeling he'd enjoy doing a nice ream job on me. What do you think?"
"I think the two of you are even wilder than me," he told her, "but I think you're right about a nice reaming."
Adam and his son went to the couch to admire and play with her ass while the girls watched, not knowing what the proposed reaming was all about. They watched as Adam showed his boy how a tongue should be curled into a roll so that it could be worked up an asshole just like a cock. Dean had so enjoyed kissing and licking her crack that he knew it would be sheer delight to get his tongue right up Mary's bung and use it as a prick to ass-fuck her. There was no trace of apprehension, no thought of taste he could encounter there. Her bung was a beautiful little ring in the valley of her ass and he wanted to ream her.
Crouching behind her, he rubbed his hands over both smooth cheeks, and probed her crack with a gentle finger as she trembled and sighed. Then he was holding her well-fleshed hips as he licked up and down her crack.
When he decided that her ass crack should be wetter, like her cunt, he poured saliva into the top of it and watched it trickle all the way down through her crack into her crotch, to make her cunt even wetter. With a gentle hand, he smeared the juice over her pussy. His face returned to her beautifully arched, white ass and went between the cheeks to plant a loving kiss on her butthole, a kiss which made her tremble with lust.
Mary groaned that she wanted to see the boy as he worked on her ass, and Adam hurried away, returning with a mirror which he positioned against the other couch so that she could watch. When the mirror was in place, Mary groaned at the sight of the boy with his face pressed between the big cheeks of her butt, looking a; though he was trying to get his whole face up her asshole.
And then she felt his tongue probing, trying to curl into the tight bung. Trying to help him, Mary used her ass muscles as though she were shitting. He felt her brownie pushing out to meet his tongue, and as it opened, his tongue pushed inside.
Wrapping his arm tightly around her big thighs, Dean kept his face pressed against her ass. Then his tongue was working in and out of her bung as she panted with lust and tried to describe the thrill of the reaming to the others, who stared in disbelief as Dean went on tongue-fucking her up the ass. Finally it became too much for Mary, and she had to tell him she couldn't take any more.
Dean wore an expression of regret as he let his tongue come out of her shitter and pulled his face away. Before he let her go, he planted one loving, moist kiss on each cheek of her ass, then got to his feet, looking very pleased with himself.
"Finish up the job with your big cock, lover," Mary panted as her naked butt swayed. "Stick that big prick up my asshole and fuck me blue."
Delighted, Adam told her he'd get the Vaseline, but she told him to forget it and slip it to her dry, adding that the boy's mouth had prepared her asshole enough for his big cock.
In no mood to argue, Adam knelt behind her, his pecker throbbing with desire, and steered his cock between her asscheeks.
The children moved in close, watching the prickhead as he guided it to the bung which looked much too small to admit his dong. Then with a groan, Mary felt the cockhead push into her asshole, stretching it as it had never been stretched before.
Dean watched the head of his father's prick vanish up Mary's butt; then he wanted to see something else so he lay face up on the bed, working his way until he was lying with his face under her wide-open crotch. He reached up, rubbed her wet, warm pussy, then slipped a finger into her slit and began fucking her with it. Mary let him know what a brilliant idea that had been as he went on fingering her twat while his father fucked her up the ass, delighting her and the girls, who stared in mounting arousal, each of them thinking that Dean would soon be diddling them that way, wondering how it would feel.
Adam went on buggering her big ass, his belly making exciting sounds as he allowed it to spank the big cheeks; then the tightness of her asshole provided more friction than he could stand, and he couldn't hold back his load.
Panting the message to her, he gave her bung a few more strokes of cock, then pressed tightly against her warm, white ass. His load exploded strongly, shooting up into her butt in shot after shot as she purred.
But Mary's purring changed to other sounds as the boy's stroking finger triggered a climax which she enjoyed with Adam's cock still up her asshole. It was a wonderful orgasm and seemed to go on forever.
Faced with the available asses of the two girls, and having only one cock to serve them, Dean didn't want to risk offending one girl by choosing the other, so he tossed a coin, hoping it would win him a ride on Emily's bigger ass. When it fell tails, appropriately, he smiled and led Emily to the couch. As he did, Adam went to get a jar of lubricant; then he went to the couch, and he was gentle as he greased his daughter's bung to provide an easy film on which his son's cock could ride. Because of the smallness of Dean's cock, Adam wasn't sure that her brownie needed lubricating, but he decided to take no chances.
As Adam pulled his finger out of the greased butthole, Dean hurriedly knelt behind his sister and used both hands to fondle her pretty ass. He wanted to play awhile with the silken cheeks, but acting like a bossy big sister, Emily told him to hurry and get his cock up her ass.
Her attitude annoyed him, and he told himself he was going to have a talk with his father about that; he rubbed the head of his dick on her bung for a few seconds, then gave a slow push and his prick slipped into the greased brownie with ease. He took his time and slowly fed the rest of his cock up her shitter. When it was all the way in, he pressed against warm, smooth asscheeks and felt his prick throbbing in her tight butt.
He held her by the hips then, as his father had held Mary, and then he was buggering the girl, doing it slowly, loving the feel of his cock pumping in and out of the very tight hole. He saw Mary kneeling close to Emily and reaching under her to play with her tits, making it more exciting for Dean as he went on riding his sister's ass.
Because he had already shot a load, Dean was able to keep the ride going for a long time. But then he reached the stage where it could be extended no longer, so he began riding her ass with fast strokes, making her grunt and groan, and then his sperm pumped up his sister's ass with very strong force.
When it was all over and Dean had taken his spent cock out of her bung, Emily decided that fucking up the ass couldn't begin to compare with taking it in the cunt, yet she thought it was an interesting game and that from time to time it would serve as a nice change of pace.
Deciding that her daughter looked neglected, Mary went to the couch with her and soon had her writhing in lust as she sucked her little titties and played with her hot little cunt until the girl was crying for a come.
Raising and parting Sharon's pretty legs, Mary pressed her face into the warmth of the sweet young crotch and began sucking her cunt. She sucked well, and it wasn't long before Sharon's legs scissored a message of ecstasy as a strong orgasm enveloped her and took her for a beautiful rocket ride. The ride proved to be a long one, such a long one that along the way she passed through heaven and kept on going.
