Diane Henson couldn't sleep. As she lay in bed staring up at the ceiling and listening to her husband snore, her mind kept circling back to the conversation she'd had with her daughter earlier that afternoon.
She hadn't meant to snoop, but when she entered Christina's room to do her laundry and saw her daughter's diary lying wide open on the floor, she just couldn't resist sneaking a peek. Although the mother-daughter pair shared a lot of physical features, their personalities couldn't have been more different. Diane was chatty and personable, while Christina tended to be an introvert and rarely shared her feelings, particularly with her mother. Despite her nagging conscious, she couldn't resist the opportunity to get a glimpse of what was going on in her daughter's head.
In hindsight, she wasn't sure what she was expecting to find. Some gossip about her schoolmates, perhaps? Or, if she was lucky, some juicy tidbits about a new romantic interest. Never in a million years did she expect to read a detailed account of how Christina had masturbated while spying on her cousin.
Once the initial shock wore off, though, she realized that maybe the two of them experimenting sexually wasn't such a terrible idea. She was fairly sure that Christina was completely inexperienced when it came to sex, and she knew that Danny would never do anything to hurt her. They would both be going off to college soon, and Diane worried that her daughter wouldn't be prepared for the kind of attention she would undoubtedly receive from her fellow co-eds. It was certainly an unconventional arrangement, but she preferred the idea of Christina losing her virginity to someone she loved, rather than with some random boy at a party.
When she confronted Christina and encouraged her to tell Danny how she felt, it seemed like the right decision. Now she wasn't so sure. Giving her daughter permission to seduce her own cousin broke just about every rule in the parenting handbook. She knew that the consequences could be severe if anyone but her ever found out.
Suddenly, her musings were interrupted by the muffled sound of footsteps. She knew instantly that Christina was sneaking out to see Danny. When the sounds passed, she carefully crawled out of bed and went to the back window. Sure enough, she could see her daughter making her way across the yard. Diane watched as Christina knocked on Danny's bedroom window. There was a momentary pause before he appeared. For a moment, she wasn't sure he was going to let her in, but after the two of them shared a few words, he opened the screen, and Christina crawled inside.
I guess there's no turning back now,
Diane thought. In a way, it was a relief knowing that the situation was out of her hands.
She kept watch until she saw Christina return to the window and shut the blinds. Deciding that there was nothing more to see, she crawled back under the covers, careful not to disturb her husband's slumber. She again attempted to close her eyes and fall asleep, but her mind was more distracted than ever. Despite her best efforts, she couldn't stop herself from wondering what was going on next door. To make matters worse, thinking about the incestuous sex happening in her nephew's bedroom was starting to turn her on.
Contrary to what she'd lead her daughter to believe, this was not her first exposure to the idea of incest. Her interest in the topic started at a sleepover she'd attended as a teen. Her friend, Tammy, had discovered her father's stash of pornography, and they'd spent most of the evening flipping through his collection of dirty magazines and novels, giggling at the lewd acts depicted in those pages.
One item that caught Diane's eye in particular, was a short paperback novel she found near the bottom of the box. The cover showed a hand-drawn illustration of what appeared to be a father and son sitting side by side on a couch. A naked young girl was straddling the man's crotch, while a move voluptuous, older woman did the same to the boy. She'd found the more conventional porno magazines to be pretty boring, if not silly, but something about that image piqued her interest. When Tammy went to the bathroom, Diane hid the novel under her sleeping bag, resolving to take a closer look after lights out.
When her friend finally went to sleep, she pulled out the novel and read it cover to cover by the dim light of a street lamp coming through the bedroom window. She was utterly scandalized when she realized that the story was about a suburban family, much like her own, and their descent into a life of incest. There was something so filthy and forbidden about the thought of family members having sex with each other, and at the time, it was hard for her to imagine that Tammy's straight-laced father would read such a thing. What surprised her most of all, though was how much the story turned her on. As she read, she wanted more than anything to reach down and play with herself, but she couldn't risk Tammy waking up and discovering her.
When morning finally came, she returned the novel to where she'd found it with a disappointed sigh. She lost touch with Tammy shortly after graduating high-school, but she never forgot about that filthy novel or the way it made her feel.
As her son, John grew into manhood, she was often reminded of the slutty mother she'd read about all those years back. She knew that most people would think it was disgusting and wrong to entertain sexual thoughts about their own children, but she didn't care. John was a sexy young man. He was tall and muscular with a handsome profile that she knew drove the girls at school crazy. She couldn't help but wonder what it would feel like to be pinned down beneath his hard, athletic body, while he had his way with her. The fact that she was his mother was irrelevant. Or at least that's what she told herself. Her fantasies had become less frequent in the three years that he'd been away at college, but they inevitably came flooding back whenever he returned for break.
Despite her naughty fantasies, she would never allow herself to act on them. Incest was fun to imagine, but had absolutely no place in the real world.
Of course what she'd read in Christina's diary earlier that afternoon had forced her to reconsider that position. The sharp line she'd drawn between fantasy and reality no longer seemed quite as clear.
Now it wasn't just her son who dominated her fantasies, but her daughter and nephew as well. Her mind was filled with images of Danny and Christina engaged in all manner of sexual activities. She pictured Christina sucking Danny's cock and wondered whether he'd go down on her as well. The thought of her nephew burying his face between her daughter's legs, causing her to pant and moan in unbridled pleasure, made her shiver with excitement.
Her pussy began to throb as she pictured the two of them together. She knew that fantasizing about her daughter and nephew having sex was wrong on so many levels, but she couldn't stop herself. Unable to ignore the sticky heat between her legs, she pushed her hands under the elastic of her panaties and rubbed gently up and down her slit, using the tips of her fingers to spread her warm lubrication over her erect clitoris.
She ran quick circles over her sensitive bud with her left hand and used two fingers from her right to fuck herself in a slow and steady motion. As she played with herself, she visualized Christina bent over on hands and knees while Danny fucked her from behind, her perky tits bouncing with each thrust of his cock.
The mental images flooding her brain were so enticing that she briefly considered sneaking out of bed and going out to spy on the two of them just as Christina had done the night before. As excited as she was by the prospect of witnessing her daughter's first sexual experience, it would be an unforgivable violation of her trust. Instead, she contented herself with her fantasies and hoped that Christina would give her all the juicy details tomorrow.
The longer she imagined Danny's plowing in and out of Christina's pussy, the more she wanted to feel real thing. Her fingers felt nice, but they were a poor substitute for a hard, throbbing cock. Luckily there was one available. With a wicked smile, she turned to her side and deftly slipped her hand inside her husband's boxers. Taking him in hand, she gently stroked and massaged him, knowing exactly how to bring his soft member to life.
Ray shuffled around a bit and yawned before his breathing returned to normal. Despite his slumber, his cock quickly responded to his wife's touch. Moving slowly, so as not to wake him, Diane crept underneath the covers and fished his lengthening member out of the hole in his boxers and took a long, slow lick from the base of his shaft all the way up to his sensitive, purple head. It had been a long time since she'd woken him with up a blow-job, and she was looking forward to the look on his face when he took in the sight of her lips stretched tightly around his erection.
After several more swipes of her tongue, she opened wide and took him fully into her mouth. She never got tired of the musky taste of her husband's flesh and, she loved feeling his cock expand as she greedily devoured him. Her mind flashed back to Christina, wondering whether her daughter was currently engaged in the same activity.
An involuntary moan escaped her lips at the thought, and she sucked Ray deeper, pushing down until his shaft was fully lodged in her throat and she could feel his balls tickling her chin. She held him there for a few beats before she started rhythmically swallowing the head of his cock. All the while, her tongue slithered along the sensitive underside of his shaft. Supporting herself with one hand, she used the other to gently massaged his balls just the way she knew he liked it.
Even after all their years of marriage, she still loved sucking Ray's dick. She never seemed to tire of the sensation of his hot flesh pulsing in her mouth or the rich, musky taste of his spunk. Thinking about him fucking her face and cumming in her mouth was almost enough to distract her from the incestuous thoughts that plagued her mind. Almost... but not quite.
It didn't take long before the warm, wet sucking sensations of Diane's mouth caused Ray to wake. "Mmm... fuck, that feels good," he groaned. His voice was groggy and more than a little confused. Looking down, he could see the unmistakable shape of his wife's body underneath the sheets and smiled as he watched the outline of her head bobbing up and down between his legs. With a quick motion, he tossed the sheets aside and made eye-contact with his horny wife.
Realizing that he was finally awake, Diane smiled at him through the corners of her mouth and pulled away from him with a wet slurp. A long strand of saliva clung to her lips as she sat up before dripping sexily back down onto his erection. There was no mistaking the look of unbridled lust in her eyes as she said, "I need you to fuck me... Now!"
Ray was surprised by the desperation in her voice. Their love making had always been frequent and satisfying, but it had been a long time since he'd seen her so turned on. It seemed to be coming out of nowhere. Not one to look a gift horse in the mouth, he smiled back at her and said, "I'd love to."
The two of them quickly dispensed with their underwear, and Diane crawled up his torso, aligning the head of his cock with her dripping entrance. In one swift motion, she impaled herself, taking him all the way to the root and causing them both to whimper in delight. "Fuck, you fill me up so good, honey," she said as she started grinding on his shaft. Ray's only response was a satisfied moan. He wasn't sure what had gotten into his wife, but with the velvety walls of her pussy squeezing and pulsing around his cock, it was difficult to care.
