"Why did Brad say that stuff about being exclusive with his sister?" Carolyn asked as the video resumed playing.
"According to Mel, that was the promise their parents had them make in exchange for the lifestyle they wanted to have."
"Seems logical, I suppose," Carolyn commented as she watched Brad Petersen peel off his sister's already skimpy attire.
Carolyn noted that Melanie Petersen was every bit as well-packaged as her brother: breasts the size and shape of honeydew melon halves, slim waist, hips wide and curvy enough for easy childbirth, shoulder-length blonde hair, a full bush which proved her blonde
bona fides
, and sexy, ultra feminine legs which seemingly went on forever.
On the TV, Brad was kneeling in front of his sister who had placed her left leg on his right shoulder to open up her pubic area for his mouth. She steadied herself by holding onto the bedpost with one hand as she massaged her firm breasts and tweaked her erect nipples with the other. Then the camera zoomed in for a closeup of Brad inserting two middle fingers from his left hand into Melanie's pussy while he played his tongue all around her clit without actually touching it directly. Without thinking, Carolyn began to mimic the young man's actions on her own moistening vagina under her sleepwear. A moan from her daughter caused her to pause her actions until she realized that Tanya had gone her one step better by getting completely naked and was now lifting her large breasts to her mouth in order to suck on her own nipples.
Back on the screen, Melanie Petersen was doing some deep, guttural moaning of her own as her brother brought her to her first orgasm of the session. As she began to sink from the experience, Brad steadied her and then stood up. The pair then kissed for what seemed to Carolyn like minutes, and then Brad hopped up onto the bed and laid on his back. Melanie also got onto the bed, but knelt on her knees over her brother's calves. She leaned down and began to spit and otherwise slobber all over Brad's glorious tool — Tanya's camerawork capturing every second of her sweet assault.
Carolyn's attention was drawn back to her daughter's masterbatory efforts; noting how the girl was furiously fingering herself...
"Tanya, baby," her mother began, "build up to it. Don't be so aggressive with your kitty. Give yourself time to enjoy the anticipation..."
"But, Mom, this video always gets me revved up! I need to cum or I'm gonna get a cramp!"
"Do you want me to help you get there?"
"Seriously?"
"Well, I know what I said earlier, but having someone else stimulate my clit always made me pop."
"I guess so..."
On the TV, Melanie was now sitting astride her brother's tummy. Carolyn stood from the couch and got naked just as Melanie bent over while Brad sensually licked and sucked on her perfectly paired peaks...
"Look at what Brad is doing to Mel's tits," Carolyn urged her daughter. "He's taking his time and they are both enjoying themselves, Tanya. That's what real love-making is about: making sure both partners have a great time in bed."
"If you think that's something, Mom, just wait for what Melanie does next..."
Carolyn came over to where her daughter lay reclined and got between her spread legs. As Tanya resumed the stimulation of her nipples — pulling and twisting them — her mother began to lightly scrape her fingernails across the sensitive skin of Tanya's inner thighs; working ever closer to the girl's glistening core. Then Carolyn put her face close to Tanya's pussy and blew onto it. She got an immediate reaction as Tanya lifted her hips off the seat cushion toward her mother's lips. Carolyn didn't believe Tanya was consciously trying to get her to make contact, but that was what Carolyn did anyway.
Never before in her forty-eight years had Carolyn Smirnoff ever tasted another woman's genitals. That streak ended when she stuck out her tongue and gave Tanya's cunt a long, slow swipe from its liquid bottom to its hard, nubbin top. Tanya moaned out her orgasmic glory and — with her hands — pulled her mother's face harder onto her sex. This went on until...
"Oh, fuck, Mom... quick: you've got to watch this part of the movie! Mel's about to do it!"
Tanya released her mother's head from her grasp and Carolyn turned around on her bottom just in time to watch as Melanie Petersen moved back over her brother's dick which was standing straight up from his groin. But instead of putting his horse-cock into her, she pressed it onto his stomach with her delicate pussy lips.
"She going to grind on Brad for almost ten minutes, Mom."
"He couldn't possibly last that long before he cums all over himself."
"He does! And what's more, Mel told me after filming that Brad had not cum for five days! Five days!"
"What... was this about giving his sister as much sperm as possible?"
"Yep! Now let's both watch this. And — by-the-way — thanks for one of the best orgasms I've ever had."
"It's not
exactly
what mothers are for, but you are most welcome, darling."
For the next eight minutes, Carolyn watched as Melanie Petersen swayed and sashayed her pelvis up and back over the bottom part of Brad's boner. It glistened more than if she had poured a bottle of massage oil over it. Carolyn could tell the young man was almost instantly attempting to hold back his pent-up release. The camera could not have been more than six or seven inches from the action; it picked up every soggy sound as well as every sensuous shift of Melanie's hips. Occasionally, Carolyn could hear her daughter's excited commentary on the action until Carolyn heard Brad say something garbled to his sister. In response, Melanie rose up on her knees and grasped hold of her brother's baby-maker. With the crimson tip, she stimulated her clit, then found the entrance to her love canal into which she inserted the glans. Then Melanie dropped like a ton of love on Brad's groin while she and her brother intertwined their fingers in each other's hands. With a sound of pain mixed with relief, Brad Petersen deposited into his older sister everything his big, hairy balls had spent five days accumulating.
To Carolyn's eyes, it seemed the young man had sent no less than seven large spurts of his sticky seed up onto his sister's cervix, but Carolyn knew that the cowgirl position was not anywhere near the best one for conception. She needn't have worried, for Brad let go of his sister's hands and repositioned them under her shoulder blades in order to gently lay her back on the bed. While keeping himself sheathed inside her, Brad managed to maneuver them into the missionary position. As he did this, Mel began to work on her clit to bring herself to climax. Her efforts didn't take long, and with a loud groan, Carolyn saw the thrashing girl almost knock both lovers off the conception bed!
"Well," opined Carolyn, "that's
one
way to get pregnant..."
"Damn straight, Mom! And the two of them aren't even close to being done. I never told them, but when Melanie came at this point in the session, so did I. I had my left hand in my shorts practically the entire time!"
As the movie progressed, Carolyn lost count of the many positions these wanton siblings used, but the Petersen kids' favorites seemed to be doggie and spooning. Every time Tanya caught the image of Brad's prick exiting his sister's weeping pussy, Carolyn could see that it pulled her vagina out along with it in spite of all the lubrication. And no commentary was needed to tell Carolyn when Melanie's brother emptied his large, cum-filled sac three more times into Melanie's greedy womb: she could clearly see each pulse from the young man's ejaculations.
In over sixty minutes, Carolyn calculated that these incestuous lovers must have cum at least four times each. And in all that time, Melanie never allowed her brother to remove his fleshy stir-stick from her gooey honey-pot. Carolyn marveled that there wasn't much in the way of dialogue, but that absence was more than made up by the fiery love-making which filled the screen. She noted how her daughter was able almost always to know just where to place the camera lens so as to get the most from any given moment in the couple's sex-play. When Brad finally did extract his spent pecker from his sister, Tanya caught the image of his incestuous sperm bubbling up to the entrance to Melanie's cunt. Before any of it could escape, the young woman grasped the back of her thighs and kept her pussy pointed to the ceiling before uttering her final words...
"Right here, baby: this is where you began!" she said into the camera. "My brother and I love each other so much that we've risked committing this illicit act to bring you into this world. You will be the most loved child ever to be born! Like your father said, 'See you nine months...' Bye!"
When Tanya finally turned off the video, Carolyn was more than ready to go fuck her son... her other daughter... or them together as the Dyadomorph.
"Well, I have to agree with you, Tanya; that
was
a beautiful thing we just watched. They really love each other, don't they..."
"Didn't you love Gramps and uncle Ralph when you had sex with each of them?"
"Not so much my dad... you could say he was just a
prop
. Mom made him do it because she didn't want me to get hurt by some teenage boy who didn't know how to treat a virgin. But, like the Petersens, I would have never stopped shagging my brother if he hadn't gotten killed."
A noise off in the direction of Carolyn's bedroom alerted the two women that the Dyadomorph was now awake and heading to the bathroom — still naked. Twenty minutes later, it emerged wrapped in a towel. Carolyn could not help herself...
"Being a bit modest now, aren't we?"
"Not modest, Mom, just cold... I'm going to fix myself something to eat and then meet you in Renee's bedroom."
"Why in..."
