The next morning, Kirsten stepped into the shower, where she was joined by her parents' lovers, Natalie and Bridget. "You still need to be fucked by us, baby, and don't tell us that you don't want it, because we can tell you were turned by the sex between us and your family.", Bridget said. Kirsten had to admit that sex with Bridget and Natalie was the one part of her fantasy that had not been fulfilled. She did not resist as Natalie began to rub her body all over with soap and baby oil- just like her parents had the day before.
Bridget, meanwhile, started fondling her breasts and kissing her sweet lips. Soon, the kiss became a French kiss. Her tongue tangled with Kirsten's, and Kirsten was totally enthralled by these lovely women who often fucked her parents. She could easily see what Mom and Dad saw in them. Now, she fully understand the swinging lifestyle in all of its beauty. No jealousy, no frustration, no regrets, no hiding, and no lies- just sweet, slutty sex for everyone.
In the meantime, Natalie was rimming her ass, licking her butt-cheeks, and tasting her young cunt. The excruciatingly delightful arousal she was feeling vindicated all of her hopes and fantasies.
Lesbian sex was every bit as wonderful as she had thought it to be.
Soon afterward, Bridget got on her knees to share the sweet snatch with her good friend Natalie. The sight of the hot redhead who loved her parents loving her own pussy was enough to begin Kirsten's ascent toward orgasm. Within moment, the girls were swapping places back and forth, going from cunt to ass and back. Bridget and Natalie were even simultaneously rimming her bottom for a little while there. Despite the extent of her climax, it still took some time to complete, and every touch of her anal and vaginal areas by these ladies was making the delay more tantalizing.
Finally, Kirsten was cumming into their mouths, and they decided that it was her turn to pleasure them. She was ordered to go down on Bridget first, and then eat Natalie out. She really did her best, giving Bridget everything she could remember being given by her. She ran her mouth and tongue all over the vulva, parting the cunt lips, and sucking on the clit. The fact that Bridget had a tongue ring, and had used it on her sex, resolved her at this point to get one herself, because she could tell that it made a difference in cunnilingus, and probably in fellatio as well. Still, she gave it a worthy shot, and she could sense the gratifying climax of her new lover, as Bridget, while kissing Natalie on the mouth, was being increasingly turned on by the delicious licking of her vagina. Finally, Bridget actually came, and the degree of her orgasm was signalled by the amount of girl-juice dripping into Kirsten's waiting gullet.
Then, Kirsten moved toward Natalie, prepared to lick her cunt, but was stopped short by the sound of a sharp command, "No, Kirsten, my darling girl, I want my ass kissed first! Do my butt, and use your fingers, too!". Sweet Kirsten naturally obliged, and the taste of female ass was so exquisitely delicious, that she felt like she could cum herself just from eating it. She spread her cheeks again and again, sucking, fingering, and licking that succulent backside. After a few minutes, Natalie fully climaxed, letting Kirsten taste yet more tasty anal cum (her first had been Vicki's). She could have died happy that second, ingesting the sweat of a beautiful babe's bottom.
After that, she reamed Bridget's butt the same way, and found that she enjoyed it even more than did Natalie. Bridget's reaction to butt-licking mouths was inevitably a total orgasm, which caused her to shriek like a banshee. She eagerly came into Kirsten's throat, as the young woman found this 3rd ass-rimming experience to the best yet.
Now, it was Natalie's turn to get her pussy wet. She was teased a little by Kirsten, but soon the girl was determined to make her go off like a missile. Once she was finished eating these women, they helped her with the rest of the shower, and she began to wash them as well, making it a 3-way bathing experience almost as hot as the Sapphic threesome that they had just undergone.
Suddenly, there was a knock on the door- it was Karl, and he wanted some of his sister- he wanted to fuck her in the ass this time. Kirsten was only too pleased to oblige him here, and she stepped out of the bath to bring her friends with her. Karl was only expecting his sister's butt to be his, but now he would get 2 more asses.
They went to his bedroom for fucking good 4-some. He got on top of Kirsten, eating her cunt and ass first, getting her wet from his oral attention, even as Natalie started to lick his balls and Bridget stuck a long finger in his butt. He then moved decisively, shoving his dick into Kirsten's bottom, and he could tell that, through her pain, his sister was enjoying the experience of anal incest so much that she was turning red all over. All of the nerves seemed to concentrate on that region. She screamed her pleasure and agony at the same time. She finally managed to speak, "Karl, that was so great- I can't believe that I would love it so thoroughly, and without lube, either! Wow! Sweet Karl, promise me that you'll always fuck my ass on occasion, no matter who you're with at the time- won't you promise me that, my sweet brother?" "Kirsten, I promise you exactly what you just asked, and I hope that you'll swear that you'll give me the use of your pussy whenever I need it.", Karl answered her. At that moment, he finally relieved his balls and cock, shooting into her butt.
That got Natalie to beg him to fuck her ass next. "If you're so great at buggering girls, that your own sister wants to keep you as a booty call, then I want you to really give it to me as well. He got up and was ready to fuck her bottom doggie-style, but Natalie said, "Not that way, boy- you need to try it different ways, and so I want to show you the porno way of sodomizing a girl." She got on her back, lifted her legs like a woman normally would in missionary-style fucking, and gestured for him to insert his penis in her rectum as it was just above the bed. He was no dunce, so he picked up on the non-verbal message and began to pound her pucker while standing, with her legs wrapped around his neck.
In minutes, Natalie was absolutely speechless, so fantastic was this anal experiment. She was soaked all over her sex, which turned Bridget on so much, that she just had to thank Karl for being so nice to her girlfriend. She took out a strap-on dildo with thigh harness, walked over to Karl, and whispered in his ear that she wanted to join the cluster. Thinking that she meant to use the dildo on Natalie, he agreed. She surprised him by walking over to Kirsten, who was busy masturbating, sticking a finger in her cunt, pulling out after wetting her pinky, and then applying to his own bum. She even kissed and licked his ass for a few seconds, clearly determined to get him as hot as the sun. Then she paused to put on the harness and dildo, tiptoed toward him, spread his cheeks again, and penetrated his posterior, while Kirsten watched in mixed shock and arousal. Needless to say, Karl was even more stunned, especially when he realized how horny it was making him. Soon, the train was in full gear, with Bridget riding Karl, and Karl riding Natalie. Like father, like son, thought Bridget, as she butt-fucked Karl- Dan loved this just as much as his boy.
All of the sudden, Karl came into Natalie, with his ejaculation spurred on by the stimulation of his prostate. Natalie then came, and Kirsten decided to 69 her, taking advantage of the group climax. She quickly released her own juices into Natalie's mouth, and this sight was the final key to Bridget's orgasm. She had another of her banshee-like cumming screams to indicate her pleasure. At last, she pulled out of his bottom, and suggested that Natalie switch places with her.
The ravenous blonde agreed, and Bridget got to feel Karl's cock getting stuck in her butt, while Natalie did some sticking of her own. Karl felt the awesome fullness of the dildo in his tush again, while Kirsten stayed on for a 2nd 69- this time with Bridget. She tasted Bridget's delicious womanhood yet again, relishing the nectar-like flavor of it. They kept up this wonderful 4-way frolic for another half hour, with Natalie seesawing in and out of Karl's ass, Bridget's butt feeling the painful pleasure of his penis, and Kirsten sharing that sweet 69 with Bridget. After they came in succession this time, however, they were all too fatigued to do any thing else but rest for a little while.
In case you're wondering what happened in the shower after the four of them left it, well, it was soon full again, because Trent, Vicki's older son by a previous relationship, now a good 32 years old, was there in all of his mature, yet vigorous manhood. He was just minding his own business, when Vicki opened the door without knocking and knew that her firstborn was behind the curtain, singing as usual. Well, she thought, I'll give him something to sing about! She simply removed the curtain and jumped in the shower with him, fully nude, as she had never bothered to get dressed (Vicki loved to be naked, and only wore a little clothing as she could get away with). He turned around, seeing his mother, and was absolutely incapable of speech. He seemed catatonic for a moment.
Then Vicki seized the opening, "Trent, my boy, I love you, and I want to take care of you, even if you are too young for the ways that I used to do it. Now, I'll just have to take care of you the way any real woman would take care of a man- by fucking you out of your mind!" Not waiting for an answer, because the look of pleasant surprise on his face said everything, she knelt and began to suck his cock with a intensity that marked her as the sweet, submissive slut she really was. He was her son, and she was going to do right by him, damnit! She gave him such a cock-sucking that his knees nearly buckled from the sheer force of it. When he came into her mouth without warning, she not only did not scold him for not asking her permission to fill her with his cum, she rewarded him for his initiative by showing some of her own. She asked him to turn around, and when he did, she spread his butt-cheeks and started munching on his ass. He was stunned by this treatment, but hardly inclined to complain about it. Here was his own mother, licking his butt like it was cotton candy!
Once she had pleasured his posterior, she asked him to return the favor, saying, "Trent, baby, would you please fuck your mother's cunt, which has already had your brother Karl, and desperately wants yours as well." He answered readily, "Mom, after what you just did for me, I would be a terribly ungrateful son to deny your request- I'll gladly fuck your pussy. Give it up for your firstborn, as you did for your 2nd!" With that, she got in front of him, and wrapped herself around him to take his cock standing up- always a sexy position as she was concerned, and apparently Trent agreed with her, because he was soon thrusting furiously into his Mom's cunt, oblivious to the newest member of the party- his stepdad.
Dan applied some baby oil to lubricate his stepson's virgin ass, and then used his fingers to make the passage even easier. Finally, however, it was time to fuck his wife's handsome boy's behind, and he eagerly entered Trent's rear. Both Trent and Vicki were amazed at this, since Dan had hitherto only fucked women, but neither of them tried to stop, as they were just too turned on- besides, Dan had the right to fuck whomever he wished, especially in his own house. No one opposed this patriarch's will, and everyone liked it that way. Dan pounded away at Trent, while the young man fucked his own mother eagerly, particularly since he was sure that Dan would treat him the same exact way that he treated her. After good 30 minutes, the slippery threesome sank into exhaustion, as Dan released his cum into Trent's now quite willing backside, and Trent gave his mother the full contents of his scrotum.
The barbecue was quite interesting indeed that evening, as each of the participants began to first blush, and then tell about their encounters to the rest, all of whom were very happy, and horny, to hear about them.
