Kirsten's Incestuous Orgy

Note : This story is completely fictional!

Dan and Vicki had been married for 18 and a half years, and their daughter Kirsten, with her fraternal twin brother Karl, had been born 6 months into the marriage. Speaking of their union, it was always a happy one, since neither of them was the jealous type- they were both swingers, and had several flings, affairs, and lovers over the years.

They had 2 other kids, Cassandra and Hector, but these were too young to figure into this story (expect one set 2 years from this point later). Anyway, Karl and Kirsten had just recently graduated from high school, preparing for their 1st semester at college. Kirsten had been keeping a secret from her family for 5 years- she wanted to have sex with them. She lusted for her brother Karl, but much more desire was in her heart for her parents, both of whom were hot as Mercury.

Dan found out about this once, when he was "snooping" for drugs, and he discovered an open diary (she must have "forgotten" to lock it).
In it were graphic depictions of what the then 16-year old Kirsten wanted to do with him, Vicki, Karl, and even some of their lovers.
Being an enlightened, open-minded father, Dan naturally regarded these writings as flattering and sexy, instead of being judgemental. He did, however, show them to Vicki (not to Karl, though). She shared his liberal attitude about the whole matter, and they agreed that, as soon as she turned 18, Kirsten would get her wish.

Today, a hot summer Southern day, Dan and Vicki agreed that it was time for Kirsten to be initiated into the family's lifestyle. Cassandra and Hector were at a teenage retreat for an environmental- ist group, so they knew that they would never get a better chance at Kirsten's pussy. They waited until she got home from shopping at the local mall, then they approached her and asked her to sit down for a moment with them.

"Sweetie," Vicki (not the dominant partner, but definitely the more outspoken one) said, "We want you to know, but not to panic, that we found your diary and its contents the summer before last. Dan found it first, and he showed it to me. I must admit that I was shocked at its substance, but Dan and I think that sexuality is a good, natural, healthy thing- including fantasies. As long as they don't involve hurting children or innocent people, it's OK to even act on them. We were wondering if you still felt the way you did then."

"Mom," Kirsten, stunned, responded,"This is kind of embarrassing, but yes, I still feel lust for you guys, including Karl, but especially you and Dad. Why do you ask, anyway?"

"Honey, it's just that we were thinking that it might be good to go ahead and act out your fantasies now, before you or us get old and you regret having them unfulfilled.", Dan answered her.

"Do you mean that both of you are willing to have sex with me? Isn't that incest? Are you saying that it's OK to do that?", Kirsten stammered.

"Yes, darling, it's perfectly alright for consenting adults to even commit incest- after all, Dan had a vasectomy a few years ago, so the whole genetic thing is not a factor.", Vicki stated, "We have good enough genes, anyway, that occasional incest would do no harm. So, do you want to fuck us, to sleep with your parents?"

"Oh, yes, Mom, I really do- are there any ground rules?", Kirsten asked.

"Just assume the submissive role- we are your parents, so that is logical enough, isn't it.", Dan spoke.

At that, the couple led Kirsten into their bedroom, where they proceeded to undress her like they did when she was younger, and Vicki went into the bathroom to get the bath running. Once she was finished, she rejoined Dan and Kirsten in the bedroom, stripped to complete nudity, and Dan began to do the same. When all 3 were naked, Dan and Vicki carried Kirsten to the bathtub, put her in it, and started bathing her body with soap and her hair with shampoo.

When Kirsten was clean, her parents joined her in the bath and started to massage, lick, and kiss her nubile body. Pretty soon, she was shaken from an extremely intense orgasm. They had shared the pleasures of eating her pussy, rimming her asshole, kissing and licking her butt-cheeks, sucking her fingers and toes, and teasing her breasts with their mouths and tongues. After some 15 minutes of this "attack", they began to finger-fuck her holes- all 3 of them.
She screamed yet another orgasm.

After this, Dan bent her over in the tub, spread her legs, thighs, and ass-cheeks, and commenced the doggie-style penetration of her sex.
Vicki got in front of her face and ordered her to eat her mother's cunt, which the girl did with gusto. She was quite surprised at a closer inspection to realize that it was shaven (Vicki's body hair, like her head hair, was a rather light shade of brown). Kirsten delightfully ate her mom's womanhood. Then, Vicki turned around and told her daughter to lick her butt-crack, which was also done.

When she had made both of her parents come twice, Kirsten was lifted out of the tub, brought to their bed, tied to the posts flat on her stomach, and mounted by Dan in her ass. By this time, the girl was so aroused, her anal sphincter was more than ready for Dan's impressively-sized penis. It slipped into her bottom, and began fucking her rectum so thoroughly and energetically that she was soon overwhelmed by this backdoor climax. Meanwhile, Vicki had strapped-on a dildo, and promptly got underneath her little girl to fuck her sweet cunt. This parental DP sent Kirsten over the precipice. It had her shrieking her excitement, which completed the job of making both Dan and Vicki cum. Dan released his semen (sans sperm, of course) into her butthole), causing his daughter to feel the heat of his man-milk in her rear entrance.

At this point, Karl walked in his Mom, Dad, and sister having a 3-way, and he was sufficiently turned on that he got up on the bed and made his twin suck his cock. When he came (rather easily, since she was at her best), some of his cum spilled into his Mom's mouth, which so excited her, that she begged her husband and daughter to let her up, so she could ride her son cowgirl-style. Dan and Kirsten had no objections, as they were in the middle of a "rectal rhythm", with both father and daughter about to climax yet again.

Once Dad had filled his daughter's ass the 2nd time with cum, he got out of her anus and stuck his member in her mouth, which gladly deep-throated it. In the meantime, Vicki rode Karl hard, bringing him off easily, and then cumming herself from the sheer ecstasy of getting it on with her strapping son. The next part came when Natalie and Bridget, two of the pair's shared lovers, joined in the hot sex and started to suck Karl off. They passed his cock and balls back and forth between them with delicious passion, knowing that he was the son of their female lover, who had just fucked him to satisfaction.

Soon, Natalie was straddling Karl's face, while Kirsten got on his manhood and followed her mother's example by riding it with enthusiasm. Dan proceeded to fuck Bridget's ass, while Vicki began to lick his like it was a Sno-Cone. After a minute, she used her strap-on dildo to bang his bottom for about 20 minutes, and then she switched places with Natalie, sitting on Karl's face so he could taste his own Mom. Natalie fucked Dan's butt for about 10 more minutes, and then she swapped with Bridget, who was glad for the chance to ride Dan's bum (not a new experience for her, but naturally a pleasant one), while he pounded Natalie's cunt. 

Once he finished with the pussy, he screwed the girl's ass, and then he put Bridget and Natalie back in their previous positions, so Natalie was once fucking his ass, while he diddled Bridget- only this time, he used her pussy. After he came again, he had Kirsten face-sit her brother, while he fucked Vicki's cunt doggie-style, and Bridget rode Karl's cock. Natalie continued to butt-fuck him all of this time, but now they were all tired from this family orgy, and they collapsed in a pool of their own spit, sweat, semen, and girl-cum.

That day began a new chapter in the family album, one which they would certainly NOT show to their kids (until they were 18).
