Preface:

It's been nearly ten years since I took my first stab at erotic writing with 'The Christmas Portrait.' One of the most common questions I've received over the years is when it would receive the sequel hinted at in its conclusion.

In the fall, I decided to finally get to work on the sequel as a thank you to my readers on Lit. But before I could do so, I needed to re-read the original to get myself back in the headspace of these characters. I'd planned to give the story a light makeover as I went, but the more I read, the less satisfied I felt with the original product. Almost without realizing it, what started as a minor touch up turned into an almost total rewrite. What you'll find here is a version of my original story that is similar in the broad strokes -- the same premise, the same characters, the same beginning and ending. But the specifics are entirely new. This version is also significantly longer and does include some father/son content, though it should be pretty easy to skip without interfering too much with the rest of the story if you so desire. Undoubtedly, there will be some who prefer the original, so I will leave that one posted here, too.

Okay. Enough rambling from me. I hope you all enjoy Another Christmas Portrait!

~~~

John woke to the loud buzzing of his parents' coffee grinder, a sure sign that they were awake and starting their day. His mom, Susan, liked to get up early and drink a cup of brew before waking him and his sister. Hearing that buzz was normally a pleasant reminder that he still had some time to snooze before getting out of bed.

But not today.

It was Christmas morning, and he had no intention of sleeping in. He jumped out of bed and pulled on a pair of boxer briefs, which only partially covered the length of his morning erection. Checking to make sure no one was coming, he dashed across the hall to the safety of the bathroom.

After relieving his full bladder, he hopped in the shower. He'd been home from school for about a week, and he'd gotten in the habit of jerking off there when he woke up. It was Christmas morning, though, so he decided to forego that ritual. Even at 19, the allure of Christmas presents still filled him with a sense of excitement and urgency.

His dad, Bill, was a professor at the local university, and made more than enough money to let his wife stay home and raise their son and daughter. His parents didn't skimp when it came to Christmas gifts. It wasn't uncommon for him to receive nearly everything on his list, and he hoped this year would be no different. He bounded down the stairs in excitement before screeching to a halt as he remembered the other part of the Hamilton family Christmas tradition.

Presents were exciting, but they came at a painful price. Each year, his parents made them pose for a family portrait in front of the tree. John didn't mind having his picture taken, but it was never that simple.

The tradition started when John and his younger sister, Emma, were toddlers. Their parents traded Christmas portraits every year with Susan's brother, Craig, and his wife, Sally. Over time, the portraits became a kind of competition to see who could come up with the most garish, over the top sweaters, decorations, and costumes they could think of. When they were younger, John and Emma had enjoyed dressing up each Christmas morning, but at the ages of nineteen and eighteen, they found the ritual intensely humiliating.

As he made his way to the kitchen, John wondered what kind of tacky matching outfits his parents would be dressed in this year. He was surprised when he turned the corner and found them sitting at the kitchen table, stirring their coffee in plain white robes.

"What gives?" he asked. "Are we not doing the family portrait this year?"

"Well, good morning to you, too!" his mom replied, ignoring his question. She sleepily covered up a yawn and then flashed him a warm, if slightly sarcastic, smile.

It struck John as strange that they were wearing robes instead of regular clothes. He couldn't remember them ever dressing so casually around the house.

"I mean... Merry Christmas!" he said, recovering slightly.

"Merry Christmas," they replied, smiling up at him as he poured himself a cup of coffee. As his mom stood to give him a hug and a kiss on the cheek, she inadvertently exposed the pale, freckled skin of her upper chest to his gaze. John couldn't help it -- his eyes flicked down before guiltily flicking back up to her smiling face. She didn't seem to notice his transgression. As she pulled him into the hug, he found himself wondering what she was wearing underneath. Before he had time to let his imagination run away with him, though, she withdrew and sat back down at the table with his dad.

"To answer your earlier question," Bill said, taking another sip of his coffee and granting both John and Susan a subdued smile, "Yes. We are still doing the family portrait this year, but you might find that you enjoy the experience quite a bit more this year than you have in the past."

They'd made this claim before, but it was never true. John mentally braced himself for an earnest explanation of how much fun it would be to dress up as Santa's elves or some other, even worse indignity.

"Sure. I bet," he said, not even trying to hide his disbelief. "So, should I go put on my robe as well?" They chuckled nervously and exchanged meaningful glances. They clearly had something they wanted to say, but neither wanted to go first.

Susan cleared her throat. "Wait until Emma comes down for breakfast, and we'll talk about it," she said.

Sensing that no more answers would be forthcoming, he took a seat. For several long minutes, they sat there, sipping their coffee, and waiting. His parents kept stealing glances at each other, and at their son as well. Susan's cheeks carried a perpetual blush, and Bill tapped his feet impatiently while keeping his eyes laser focused on the stairs.

What are they so nervous about? he asked himself. His parents always took the Christmas portrait seriously, but this felt different. Maybe we won't have to do it this year, he thought, allowing himself the smallest ember of hope.

As he waited and tried to figure out what was going on, his gaze fell upon his mother. She sat in front of him with her legs crossed, exposing quite a bit of her smooth inner thigh. Naturally, he'd seen her in a bathing suit many times, but there was something about the way she wore a bathrobe in the kitchen felt out of place and exciting -- like a constant reminder that there was a naked woman underneath that thin layer of terrycloth. He knew he shouldn't stare, but he couldn't stop himself from gazing up to the opening of her robe and the slight hint of freckled cleavage it revealed. It was impossible not to wonder whether she was fully naked underneath. The mere thought made him shiver with a mixture of excitement and shame at having such a perverted thought about his mother.

Susan was a red-head with the pale, freckled skin that often went along with it. She'd just celebrated her forty-fifth birthday but didn't seem over the hill by any means. She kept herself fit through daily walks around the neighborhood and a well-used gym membership. Although she didn't have the body of a twenty-year-old anymore, she still turned a lot of heads wherever she went.

John had always known on an intellectual level that his mom was an attractive woman, but now those thoughts were bending in a whole new direction. Jesus, what's wrong with me? he asked himself, suddenly feeling guilty for ogling his mother like she was a co-ed in one of his classes at school.

His train of thought was interrupted by the sound of Emma's feet banging down the stairs. She was so excited that she almost slipped on the hardwood flooring, just catching herself on the counter before taking a painful tumble. Pulling her disheveled hair away from her face, she flashed a goofy, wide-eyed smile that was entirely free of embarrassment.

"Wow, that was a close one!" she said. His sister's carefree attitude was one of the many things John loved about her.

The early stages of their father's career as a philosophy professor required a lot of travel before he finally received a tenured position in the town they now called home. John and Emma made and lost a lot of friends throughout their childhoods, but the upside was that they were closer than many siblings their age. Even after John left for college, he still made a point of calling his sister every day to chat. Now that he was home for the winter, the pair spent nearly all of their free time together.

Emma was a late bloomer and a bit of a tomboy. She hated all things girly and tended to imitate her brother's fashion choices, preferring jeans and t-shirts over skirts and blouses. One area where they differed was in their personality. Unlike John, who was quiet and reserved, Emma was outgoing, excitable, and sometimes painfully naïve. When they got in trouble, they got in trouble together, and it was almost always the result of one of Emma's ideas.

She was her mother's daughter, and they shared the same green eyes, vibrant smile, and slim build. Unlike her mom, though, Emma's freckles were limited to a small patch on the bridge of her nose, and her hair was a rich honey blonde. Her pixie-like features inevitably lead strangers to assume that she was much younger than her eighteen years, something that she'd always tried to counter with her brash, outgoing personality.

Despite her near wipeout, she'd managed to break the tension in the room, much to her everyone's relief.

"Hey, what's the deal with the robes?" she asked as she noted her parents' unusual state of dress.

"Yeah guys, spill it! Tell us what's going on," John added, glad to have Emma backing him up. "When can we open presents?"

"Hold your horses," Susan said with a knowing chuckle. Emma's mere presence seemed to have lightened the mood in the room considerably. "I promise we'll get to presents, but first we need to sit down and have a family chat about the Christmas portrait."

John and Emma let out dramatic groans.

"Can't we do that later?" Emma asked.

"Or not at all?" John added.

Susan's sly smile widened even further. "I think your attitude about the portrait will change once we show you what your aunt and uncle sent us this year."

"Pfft. Doubt it," Emma replied as she sulkily followed both parents to the living room.

The four of them took their normal seats -- Bill and Susan on the couch, and Emma and John in the recliners on either side. John couldn't help but eye the Christmas tree and the piles of wrapped gifts beneath. He also noticed that his dad's laptop was plugged in and hooked up to the back of the tv.

Strange.

There was a brief awkward silence as Bill and Susan grasped hands and shared a meaningful look before nodding at each other in silent agreement.

Bill started. "Your mother and I have something we need to discuss with you, but before we do, we need you to keep an open mind. We've made a decision about our marriage that is going to affect our family a great deal. It's something you both might have strange feelings about. All we ask is that you hear us out and try to withhold judgment until you've had some time to process. Can you do that for us?"

"Oh God. Are you getting a divorce?" Emma blurted out.

John felt a growing pit in his stomach at the possibility that his sister was right. As far as he knew, his parents had a normal, happy suburban marriage, but he was also mature enough to know that parents didn't always share everything with their kids. Maybe there was trouble brewing behind the scenes that he'd remained blissfully unaware of until now. Something had definitely been off with them in the week since he'd returned from school. There was a nervous energy between the two of them that he couldn't quite put his finger on. Was this why?

The rapid rise in Emma and John's anxiety deflated just as quickly when a quiet laugh escaped their mom's lips. "Oh, no, honey... no, no, no," she said, giving her daughter a comforting smile. "Your father and I love each other very much, and neither of us is going anywhere. Even if we were, do you think that's the kind of surprise we'd save for Christmas morning?"

"No... I guess not," Emma said, her cheeks burning with embarrassment even as her expression spoke of immense relief.

"So, what do you say? Are you willing to hear us out?" Bill asked.

Both children quickly nodded.

"Good, because there's a bit of a story behind your aunt and uncle's Christmas portrait this year. It took your mother and I a while to fully process it, and we'll understand if you need time to sit with it as well."

"Can't you just show us?" John asked. "All this buildup is kind of freaking me out."

"Me, too," Emma said.

Bill cast a questioning glance at his wife, who, after a moment of thoughtful consideration, shrugged and said, "Maybe it will be easier to just show them."

"Well, okay then," Bill said as he reached for the mouse and remote control from the end table. "But before I do, I need you both to promise that no matter how you feel about these pictures, they stay within the confines of this house. What I'm about to show you could be incredibly damaging to your aunt and uncle if anyone ever found out."

"We promise," John said, speaking for himself and his sister, his heart thumping with a confusing mixture of excitement and anxiety.

With that, the TV screen lit up with an image of their uncle, Susan's brother, Craig, and his wife, Sally, standing behind their kneeling children, Jenny and Steve, all four of them smiling radiantly at the camera. Unlike the portraits from previous years, though, they were wearing robes, just like Susan and Bill were now.

"Great... more bath-wear," Emma said, clearly unimpressed.

"Keep watching. There's more," Bill said.

The next slide showed just Sally and her twenty-year-old daughter, Jenny. They were facing the camera in their robes. Like the precious photo, this one seemed like a normal mother-daughter portrait, but there was something unusual in their smiles that John couldn't put his finger on.

With another click of the mouse, Bill turned to the next slide. The image that greeted them was like nothing John or Emma had ever seen. Their Aunt Sally's robe was opened to her waist, fully exposing her large, hanging breasts to the camera. Jenny was bent over next to her mother, sucking greedily on one of her thick brown nipples. Sally's other breast hung loosely on her chest. At the age of 48, gravity had started to take its toll, but that didn't seem to matter to her daughter, who looked like she was having the time of her life.

John wasn't sure what he'd been expecting, but it certainly wasn't this. Even after all their buildup, he still couldn't help but feel that there had been some kind of mistake -- that these images were included in the album by accident. Or maybe they weren't real at all. Maybe they were photoshopped by someone whose perversions ran deeper than he ever would have guessed possible. But who?

He cast a quick glance to his parents, expecting to see his dad fumbling with the mouse, trying to close the image, but that wasn't what was happening at all. Neither of his parents seemed concerned about the lewd images projected on their television. Instead, their focus was entirely on their children, their faces filled with nervous curiosity as they gauged the reaction to what they'd seen.

Sensing her son's confusion and anxiety, Susan said, "It's okay, honey. They wanted us to see this. You can look."

So this wasn't a mistake. These photos were real -- a fact that only led to more questions.

"Um... okay," he mumbled, numbly turning his face back to the screen, still not sure how to make any sense of what was happening.

Pushing his anxiety and confusion aside, John allowed himself to fully absorb the pornographic picture of his aunt and cousin. He'd seen plenty of porn over the years, but this was entirely different from the anonymous smut he poured through on lonely nights alone with his computer. These were women he knew -- and not just casually. They were his family. The contrast between their utter familiarity and the shocking depravity of their actions was too much for his brain to process.

His cock figured things out pretty quickly, though.

Before he could make sense of his feelings or adjust the growing bulge in his pants, the mouse clicked again, and a new image appeared. This one featured all four family members. Both women were again facing the camera, this time fully naked. John's cousin, Steve, and his Uncle Craig stood behind them. The women were leaning back against them, spreading their legs for the camera. Steve was using both hands to spread his mother's furry outer lips, exposing the wet, pink of her gash to the camera. Craig was doing the same thing to his daughter, using one hand to spread her open and the other to squeeze one of her large, round breasts. They weren't quite as big as Sally's, but were still more than a handful each.

Emma gasped.

The sound reminded John that he wasn't alone. Pulling his gaze from the tv, he saw his own shock reflected on his sister's face. Past her, he saw that his mom wasn't paying attention to the slide-show at all. Her eyes were laser focused on the growing tent in his pajama bottoms. Sensing his gaze, she glanced up, realizing she'd been caught. Blushing profusely, she looked back up at the TV screen, unwilling or unable to make eye contact with her son.

"What are you two thinking?" Bill asked, breaking the tense silence in the room.

"I'm thinking that I'm ready for that explanation you promised," Emma replied, her expression unreadable.

This time it was Susan who spoke. "The short version is that your aunt and uncle have entered into an incestuous relationship with their children. We don't know all the details, but it's been going on for a few years -- ever since Jenny turned 18."

"But why?" Emma asked, looking genuinely confused.

"Because they enjoy it," Bill said. "Although I'd think that's rather obvious," he added with a nervous chuckle as he drew their attention back to the screen.

"But that's so sick!" she exclaimed.

"I understand why you might feel that way. We thought the same thing at first, too," Susan said. "It took us at least a few weeks before we were ready to think rationally about their lifestyle and ask ourselves whether what they're doing is really so wrong."

Emma stared dumbfounded back at her mom, her mouth hanging half open in stunned silence. "Whether it's wrong?" she repeated. "They're doing things... sexual things... with each other! In what universe is that not wrong?"

"I want you to do something for me," Susan replied. "Take another look at the image and tell me what you see."

"What if I don't want to?"

"Then I won't try to force you. But if you really want to understand what I'm getting at, then play along with me -- for a bit longer, at least."

Emma let out a frustrated groan, but she did as her mom asked. "I see Jenny and Aunt Sally. They are naked, and their legs are spread, and Steve and Uncle Craig are touching their..." She couldn't bring herself to use the word that was on the tip of her tongue -- not to her parents.

"Their pussies," Susan said, finishing her sentence.

The sibling's eyes snapped back to their mother. They'd heard her let out an errant 'shit' or 'damn' occasionally over the years, but nothing like this. They didn't think of her as a prude, but it still felt immensely strange to hear her use such crude language in such a matter-of-fact way.

"Fine, their... pussies," Emma repeated as a faint blush spread over her cheeks.

Susan nodded. "What else do you see?"

"Uncle Craig and Steve are behind them."

"Mmhmm. What else?"

"I..." Emma hesitated. "I don't know. That's all, I think..."

"Look at their faces," Susan said. "What do you see?"

"Um... They look happy, I guess?"

"You know your cousins pretty well. Does it look like either of them are uncomfortable with what they're doing?"

"No. They look like they're really into it," Emma replied.

"They are really into it," Susan replied. "And to hear Craig and Sally tell it, their family has been closer than ever since they started fucking."

Once again, Susan's language crashed like a hammer blow against the carefully constructed image of her that lived in John and Emma's minds.

"The point your mom is trying to make," Bill said, "Is that your cousins are consenting adults. What the four of them are doing together may be unusual, or even socially unacceptable, but as long as they are all enjoying themselves and not hurting anyone else, then who are we to say that what they're doing is wrong?"

"I... um... I guess that makes sense," Emma mumbled, reluctantly acknowledging defeat as she sunk back into her chair.

Although she took great pains to hide it, Emma felt an unexpected sense of relief as her parents spoke up in defense of their extended family's incestuous lifestyle. She could barely admit it to herself, much less say it out loud, but she'd harbored secret incestuous desires of her own.

As she entered her teen years, and her friends started showing interest in dating and other adult pursuits, Emma felt more and more attached to her older brother. She would happily acknowledge that some of the boys she shared classes with were cute, but they could be immature and small-minded, too. All they ever seemed to talk about were sports and which girls had the biggest boobs.

Her brother, on the other hand, was quiet and caring. He always took the time to understand her, even on the frequent occasions where she put her foot in her mouth. John was tall and skinny, with their mother's sharp, angular features and their father's blue eyes and straw-colored hair. She thought he was devastatingly handsome and could never understand why he seemed to be perpetually single.

Emma couldn't pinpoint exactly when it started, but in those secret moments late at night when she touched herself while imagining it was someone else's fingers rubbing between her legs, it was her brother's face who smiled kindly down at her, making her feel so safe and loved as he violated her. The intense release those fantasies brought her was matched only by the feelings of shame and revulsion that followed. She told herself that each time would be her last, but she just couldn't help herself. Trying to suppress her feelings just made her orgasm even more powerful when she finally relented and gave in to her twisted fantasies.

Her fantasies had grown less intense when John left for college, but now that he was home, they'd come back even stronger than before. She'd tried to make peace with the fact that nothing physical would ever happen between them, but now her parents, of all people, were trying to convince her that the source of her greatest shame was perfectly normal, even as she felt more sure than ever that John wouldn't feel the same way about her.

She couldn't ignore the way John looked at the pictures of their aunt and cousin. He could barely hide his arousal at the sight of their big naked tits. He'd certainly never look at her that way. It all felt like a cruel joke.

"I still don't really get why you guys are showing this to us, though," John said. "Like, sure. They can do whatever they want, but why tell you about it? And for that matter, why are you showing us?"

"Ah. The question of the hour," Bill said with a nervous chuckle.

Susan took her husband's hand in hers and gave it a firm squeeze. "No more putting it off, dear," she said. "We owe them the truth."

Bill swallowed and gave a terse nod. That same nervous tension Emma and John had sensed earlier was back in full force. They waited with silent attention, bracing themselves for whatever revelation was to come.

"Your question earlier, Emma -- about us getting a divorce," Bill said, hesitating once again. "This is hard to admit, but if you'd asked us that a few months ago, you might have gotten a different answer."

"Marriage is a wonderful thing, but it can be difficult, too," Susan said. "Your father and I have certainly faced some trials over the years."

"I had no idea," Emma said.

"Me either," John added.

"And that's how we always wanted it to be. It's our job to worry about the two of you. Not the other way around."

"What was wrong?" Emma asked.

This time, it was Susan's turn to blush. "Twenty years is a long time. Even in a strong marriage like ours, things can get kind of... stale... in the bedroom, I mean."

Susan's words hung in the air for a moment or two before Bill came to her rescue. "Your mom and I love each other as much as ever," he said, draping his arm over her shoulder as if to emphasize his point. "But things had gotten kind of... routine. Boring, even."

Bill and Susan shared another meaningful look. John and Emma could see the pain they shared, but it seemed like an old wound -- one that had healed but still left a scar.

Susan continued. "Your father and I married young. We were each other's firsts. It took us a long time to admit it, but we both wondered whether we'd missed out on some things along the way -- whether there were aspects to our sexuality that we still wanted to explore. We considered trying an open marriage, but neither of us had the first idea where to start."

"So, what did you, um... do?" John asked, silently wondering if he'd ever have a conversation more awkward than the one he was currently in.

"That's where your aunt and uncle come in," Susan said. "I confided to Sally during one of their visits, and she told me that her and Craig had gone through a similar rough patch a few years back."

"Which they resolved by having sex with their kids?" Emma asked.

Susan nodded, unable to meet her daughter's gaze.

Bill picked up where his wife had left off. "Their decision didn't just come out of nowhere. Your aunt grew up in a sexually open household. She lost her virginity to her father and regularly had sex with her siblings as well. That all stopped when she met Craig, or at least it did until she introduced the idea to him when Jenny turned eighteen, and... well, you can see how things turned out," he said, pointing with his eyes at the lewd image still splayed across their television screen.

John's head reeled at these revelations. Even after everything he's seen and heard, it was still hard to imagine his aunt and uncle, who he'd known his entire life, doing something so depraved. But he didn't have to imagine it. The proof was right there on the screen.

"Oh... Oh, God..." Emma said. "I know why you're showing this to us."

"What? Why?" John asked.

"They want to do it, too."

"Have sex with Aunt Sally and Uncle Craig?"

"No, dummy. They want to do sex stuff with us! It's why they're wearing robes and why they are showing us these pictures. They're probably naked underneath and just waiting for us to give the go-ahead." Wheeling on her parents, she said, "I'm right. Aren't I?"

Susan and Bill hesitated awkwardly. Of course, their daughter was entirely correct. This was the moment they'd waited for since they'd made their final decision weeks ago, but now that it was upon them, they weren't sure what to say.

Emma wasn't always so perceptive, but he knew his parents well enough to see that she had hit the nail on the head this time. He thought back to the brief glimpse of flesh he'd seen in the gap in Susan's robe only a few minutes prior. What at the time had seemed like an accidental slip -- something he'd gotten away with -- now felt purposeful in a way that blew his mind. His cock, which was already uncomfortably hard from the sight of his aunt and cousin's nudity, surged with new arousal.

Unlike Emma, John had never fully considered the possibility of having sex with a family member. Now that the opportunity was before him, though, he found the idea appealing in a way that he couldn't fully comprehend. On one hand, this was the woman who had raised him, who had tucked him into bed as a child and comforted him in times of distress.

She was also a sexy woman. One who was, apparently, offering herself to him on a silver platter. John had always been shy around girls, too self-conscious to risk the embarrassment of rejection. The idea of a beautiful woman eagerly propositioning him for consequence-free sex seemed like a gift from the gods. And as confusing as it was, the fact that the woman in question was his loving mother, someone who he knew cared for him deeply, just made the whole proposition even more exciting.

"Are you serious?" he asked, already knowing the answer.

Bill nodded. "This is something your mom and I have spent a long time wrestling with. It took a lot of courage for your aunt and uncle to tell us the truth about their lifestyle, and I'll admit that we were pretty freaked out at first. The more we thought about it, though, and the more they explained things to us, the more it all made sense. Why bother with the messy emotional entanglements and pitfalls that come with inviting new sexual partners into a marriage when there are two sexy and willing partners at home who they already have a close, loving relationship with?"

"And I bet you think we're sexy, too. Right?" Emma asked.

"We really do, sweetie," Bill said, staring directly into his daughter's soul.

"Oh..."

It was the only thing she could think to say. She'd expected the question to throw him off and wasn't at all prepared for the direct honesty of his response. More than that, though, the way he looked at her -- as a sexual object as well as his daughter -- made her pussy absolutely cream with desire.

"More than anything, we want you both to know that we love you and would never want to do anything that might damage the relationship we have as a family," Susan said. "Your father and I have gone back and forth for months trying to decide whether we should even bring this up with you. We know that, regardless of what you decide, you won't look at us the same way again. But we haven't been able to look at the two of you the same way ever since Sally and Craig put this idea into our heads."

Turning to John, she said, "Having you home with us these last few weeks has been... difficult. I know what you've been doing in the shower each morning, and just the thought of it..." She cleared her throat and looked down at her feet, unable to hide her embarrassment. "I keep wondering what you would do if I just stepped in and joined you."

"Y-You do?" John mumbled, hardly believing the words coming out of his mother's mouth.

Susan raised her head and stared at him dead on. The look on her face was like none he'd ever seen before. Her eyes were big and wide -- somehow appearing excited and terrified all at once. He didn't need for her to say a word to know that she was absolutely sincere.

"You probably think I'm sick. A bad mother. I know I am," she said, her voice thick with emotion. For a moment, John thought she was going to cry. "If you don't want this, I'll completely understand. Everything will go back to the way it was. We'll never talk about this morning again. It'll be like it never happened."

"No! I don't think that," John exclaimed, suddenly afraid that the opportunity his mom was offering him might slip away as quickly as it had arrived. "I just... What's a guy supposed to say to something like that?"

"You could tell me what you're thinking. How you feel about all of this?" Susan replied, feeling relieved that her son hadn't closed the door on anything. Not yet, at least.

John hesitated for a long time as he struggled to put his thoughts in order. "I'm... I mean -- I've never..." he trailed off, but his mother immediately understood.

"Well, that's okay, honey," Susan said, switching effortlessly back into Mom mode as she scooted to the end of the couch and took John's hand. Inside, though, her heart was doing backflips at the thought of taking her son's virginity -- of teaching him to fuck. The embarrassed flush rising to his cheeks just reminded her of how much she adored her little boy. She'd woken up this morning hoping to fulfill a sexual fantasy, but now she realized it was more than that. She'd be doing something for him, too, and she was determined to make the experience as perfect and wonderful for him as she could.

"I could teach you, you know," she said, her voice delicate and low. "I could show you everything there is to know about how to pleasure a woman -- how to fuck," she added with a breathy hiss. She could hardly believe the words that were coming out of her mouth. What had seemed like an impossible fantasy only minutes ago was now almost close enough to touch. She wasn't sure where it would lead, but now that she was on the path, she felt determined to see it through.

"Oh, God, Mom..." John moaned as he squirmed uncomfortably in his seat.

A quick glance downward was all Susan needed to confirm that her boy was excited. Before she could react, though, something caught John's eye, and he snapped back to reality. Following his gaze, her heart sunk when she saw the look on her daughter's face. Emma's eyes were wide and shiny, and her mouth was pursed into a tightly controlled frown. It was a far cry from the playful, animated expression she was used to seeing there.

Once Emma saw that she'd become the center of attention, she let out a frustrated grunt and stormed off, the echoes of her footsteps ringing throughout the house as she stomped her way up the stairs.

All of Susan's nervousness and insecurity came flooding back as she looked back to her husband for support. Bill was already on his feet, ready to follow their daughter upstairs.

"No, Dad. Don't. I'll go talk to her," John said.

Susan opened her mouth to object, but quickly shut it again. Her first instinct was to go upstairs and apologize herself -- to take back everything she'd said and repair the damage they'd caused, but somehow she knew that there was nothing either she or Bill could do to fix this. She was well aware of the special bond her children shared and sensed that, no matter what she was feeling, the person Emma needed most right now was her brother.

"Go ahead," she said. "We'll wait down here."

John nodded and rose from his chair, once more feeling a wave of embarrassment at the way his pajama bottoms hung over his prominent erection. The heat in his cheeks only intensified when he made eye-contact with his father. The things his mom had said to him had so completely occupied his thoughts that he'd almost forgotten that her husband was right there with them, seeing everything that was happening.

He padded his way upstairs and knocked quietly on his sister's door.

"Go away!" Emma shouted.

"It's me," John replied as he cracked her door open an inch. "Can I come in?"

There was a long pause before Emma finally said, "Fine."

What he saw when he stepped inside made John's heart sink. His sister was curled up in the fetal position on the bed, facing away from him. He didn't need to see her face to know she'd been crying.

"This is pretty freaky, huh," he said, taking a seat at the foot of her bed.

Emma rolled over to face him, her eyes bleary and her cheeks wet with tears. "You didn't seem to think so downstairs."

John didn't know what to say. His thoughts and emotions were so confused. What their parents told them was freaky, but it was exciting, too. Now concern for his little sister added yet another flavor to the bubbling stew of feelings boiling in his head.

"Would you really have done it?" Emma asked. "Would you really have had sex with Mom?"

"Honestly? Yeah, I think so," he admitted. "I know it's weird, but it's kind of exciting, too. I can't explain it, but there's something about Mom wanting to teach me about sex that's so messed up that it circles all the way back around to being hot."

"You're just a horny virgin," she said, cracking a teasing smile for the first time since she'd come downstairs.

"Oh, and you're not?" he shot back. "Don't think I didn't see the look on your face when Dad said he thought you were sexy. It was just like when Mr. Darcy jumps into that scummy pond." When their mother showed Emma the BBC miniseries of Pride and Prejudice, she'd also inadvertently introduced her daughter to her first crush. It had become an endless source of teasing from her older brother.

"Ugh! Shut up!" she groaned as she flung her pillow in his direction.

He caught it and set it aside. "Am I wrong?"

Emma hesitated for a long time before finally mumbling, "No. You're not wrong."

"So what's the problem, then?" he asked, a hint of impatience creeping into his voice. "Why don't we both go downstairs and enjoy ourselves?"

"I'm not saying I'm not interested in doing stuff with Dad," Emma admitted. "It's sick, but I get the appeal. It's just... I just don't want you to have sex with Mom. Okay?"

"What? Why?" John asked, unable to hide his growing frustration. "It's not like it would change anything between you and me. I'd still be your big brother. We'd still be best friends."

"I know, and that's the problem!" Emma said, the words bursting out of her with another flood of new tears. "What they want... What Mom wants... I've wanted it, too, and for a long longer than either of them. I don't want things to stay the same between us! I want you to look at me the way you were looking at Mom. It's all I've wanted... for years. But I kept quiet because I knew it was wrong. I knew you'd think I was a sick freak if I ever told you all the dirty things I wanted to do with you. And after all that time, after all those years trying to make peace with the fact that the one thing I wanted most in the world would never happen, Mom just seduced you like it was nothing. Like it was no big deal."

Moving on pure brotherly instinct, John went to his sister and wrapped her up in his arms. "I'm sorry, Em. I had no idea."

"I know. That was kind of the point," she sniffed.

He felt like an idiot. And worse, he felt like a terrible brother. He always thought he knew his sister better than anyone. She was the first one he'd call when he needed someone to talk to, and until a few moments ago, he thought he knew all of her secrets. He couldn't quite comprehend how he'd been so wrong. How was it possible that he'd never picked up on a single hint of her true feelings?

Pulling back, he couldn't help but look at his sister with new eyes. Emma wasn't gorgeous in a way that teenage boys tended to notice, but she had her own unique kind of vivacious beauty. She was short and skinny with wide, innocent eyes and a small, button nose that gave her a look of youthful innocence. Beyond her physical appearance, though, she had a sort of imperceptible energy to her -- an adventurous aura that promised excitement and fun to anyone who followed in her wake.

Despite her attractive qualities, his sister was one of the few women he could honestly say he'd never had an impure thought over. He'd always thought of himself as the responsible one -- as her protector. The one whose job it was to keep an even head and curb his sister's natural instincts for troublemaking and mischief. Perving over her would have felt like a betrayal of all of that.

Now, though? Now he didn't feel like being responsible or even-headed at all.

"Is this the look you wanted?" he asked as he smiled lovingly down at her and took her cheek in his hand, brushing away a tear with the pad of his thumb.

Emma stared dumbly back up at him for a moment, the corners of her lips turning up into an excited smile as the realization of what John meant finally crystalized in her brain.

"Oh, Johnny," she moaned as she practically leapt out of the bed and into his arms.

Without a conscious thought on either of their parts, they started kissing. Emma wrapped her arms tight around her brother's chest, trying to get as much skin contact with him as she could while their mouths mashed hungrily together. Neither had a clue what they were doing. There was no technique behind the way they sucked on each other's lips and drove their tongues madly in and out of each other's mouths through muffled grunts of joy.

It didn't matter. No amount of prior experience could have improved the feeling of his sister's soft pink tongue gliding wetly against his own.

As they kissed, he let his hands roam over her body, starting in her short blonde hair, then moving lower over her neck and down her back. No bra, he thought to himself as he ran smooth circles over her flesh, marveling at how oddly familiar this all was. How many times had he hugged her close or felt her warm body snuggled up to him as they watched a movie on the couch? She was just as much his then as she was now. The only difference was that now he knew it. He may have been late to the realization, but he was determined to show her that his ardor was every bit as strong as her own.

"I love you, John," Emma gasped as she finally pushed her face to the side, moaning as her brother kept kissing her cheeks and neck.

"MmmHmm..." he said, still too engrossed in the sweet and somehow familiar taste of his sister's skin to give a proper reply.

Finally, his hands reached Emma's ass. There was hardly anything there -- just two slim little lumps of flesh, barely big enough to fill the palms of his hands, but they gave him the perfect leverage point to pull her crotch close up against his.

Though separated by several layers of fabric, the feeling of their excited genitals pressing together was almost too much for either of them to take. With his hands still mauling her little ass, John leaned forward, pushing her back onto the bed and pinning her small body beneath him.

"Ohhhh... Ohhhh Yes!" Emma sighed. She lifted her arms above her head, giving her brother full access to her nubile and very aroused body.

John couldn't say what had come over him. Maybe this was a latent instinct that had been hiding inside of him all along. Or maybe it was Emma who brought it out of him. Regardless of the reason, he'd never felt more in control than he did as he roughly ground the length of his cock against the growing wet spot between his sister's legs.

"You're so sexy, Em," he moaned. "Your body feels so fucking good."

"Yours, too," she replied, lifting his chin and bringing him close for another wet, tongue-filled kiss.

With one hand firmly on her ass, guiding her back and forth against his straining erection, his other felt more free to explore, though there was only one place it truly wanted to go. Moving upward, his palm pressed against her chest, quickly feeling out the hard little pebble of flesh that pushed against the thin fabric of her shirt. Much like with her ass, there wasn't a lot there, but that didn't stop him from roughly squeezing and pinching at her little breasts.

"Mmmmmfuckyeah..." she groaned in one deep exhale. "I'm all yours, Johnny. My body is all yours..."

Without realizing it, they'd crossed some imperceptible barrier. They were falling deeper and deeper into each other with each movement of their hormonal bodies increasing the speed of the fall.

John's fingers dug into Emma's ass as he ground her covered pussy against his straining erection once, twice, three times.

Then it was all over. His vision blurred as he humped madly against her, muttering excited nonsense as he started to cum. His pajamas kept his hard cock pinned tight against his belly, but the frantic nature of his thrusts pushed the head of his prick past the waste-band of his shorts.

Emma felt a wave of delirium wash over her as she felt a splash of wet heat against the exposed portion of her belly, immediately followed by another and another. She knew from health class about semen and how boys ejaculated, but nothing could have prepared her for the reality of having her brother's cum pouring out of the head of his cock and smearing all over her skin.

Her thoughts went back to all the times she'd rubbed at her privates while imagining her older brother kissing her and touching her body. In her filthiest imaginings, she sometimes even pictured him taking out his penis and letting her touch it. But even in the midst of her most forbidden explorations, she'd never reached that sublime apex of pleasure. There was always something missing -- some secret key to unlock her deepest source of pleasure that she hadn't yet discovered.

The feeling of John's hot cum spraying out of him and pooling in her bellybutton changed all that.

"Oh, John! Something's happening! Something's happening and I can't stop it!"

Suddenly, it felt like she was wetting her panties. She would have been overwhelmed by embarrassment if it wasn't the nicest feeling in the whole world. Her hips flexed as she rutted against her brother, grinding her cunt against his hard cock with a force and intensity that was entirely out of her control. John was kissing her, but she couldn't say when he'd started. She couldn't breathe, but it didn't seem to matter. She would have happily drowned in the deep well of pleasure that seemed to pour out of her with each thump of her wildly beating heart.

Eventually, the intensity of the sensation dulled, even as their mouths kept sliding wetly against each other. They moaned happily into each other's mouths as the moment slowly slipped away.

"What was that?" Emma asked, her eyes wide with wonder.

"You came, I think," John said. "Has that never happened to you before?"

Emma shook her head. "Nope. But it was amazing! Can we do it again?"

John couldn't help but grin at the innocent glee on her sister's face. "Let's at least take a moment to catch our breath," he chuckled.

"You had an orgasm, too, right?" she asked as she slipped a finger down between them and drew a dollop of her brother's spend onto her finger and inspected the slimy substance. "And this is your... cum?" She'd heard the word before but had never had cause to say it out loud herself.

"Uh. Yeah," John replied, surprised by how little she seemed to know about the practical aspects of sex.

"I wasn't expecting it to be so warm, but I guess that makes sense. Is it weird that I got all excited when you shot it out on me?"

"I have no idea," John laughed. "I've never cum on anyone before. I think some girls like it, and some don't."

"Well, I'm definitely one of the ones who does."

There was a long pause as she seemed to contemplate something. "Do you think it's okay if I taste it?" she finally asked, looking bashful as she stared up at him. Before John could reply, her cute tongue slid out from between her lips and drew her brother's cum into her mouth. She spent a moment in silent contemplation before her eyes once again opened wide and a big smile spread across her face.

"Yum!" she said. "Want to try some?"

"Maybe another time," John said, chuckling at his sister's naïve exploration of all things sexual.

She shrugged and said, "Your loss," before scooping up another wad of cum and shoving it in her mouth.

John rolled off of her and sat cross-legged as he watched his sister happily eat the load of cum he'd deposited on her stomach. As weird as the situation was, he felt strangely at ease. He didn't feel an ounce of regret over what they'd done, only that same sense of loving connection he always felt with Emma, albeit now with a level of eroticism that hadn't been there before.

"So what do we do now?" he asked.

"Can we do it again?" Emma asked. "With fewer clothes this time?"

John felt like he'd hit the jackpot -- or rather that he'd discovered the jackpot had been in the bedroom next to his all along. He would have happily spent the rest of the day -- hell, the rest of his vacation -- sexually experimenting with his younger sister. But as much as he shared her enthusiasm, he hadn't forgotten the circumstances that led them here.

"Definitely," he said. "But what about Mom and Dad? They're still waiting for us."

"Shit! How long have we been up here?"

"Ten minutes? An hour? I have no idea."

Emma's lips pursed into a tight little frown as her gaze wandered up to the ceiling, something she did when solving a difficult problem. He also knew there was no sense in rushing her. Once she figured out what she wanted to say, there would be no stopping her from saying it.

"I feel kind of bad about how I treated Mom downstairs. It seemed so unfair that she wanted to have sex with you even though she has Daddy around all the time. But now I think I get it."

"Yeah?"

"MmmHmm. I had no idea how fun sex is. If I had two hot guys living in the same house with me, I'd want to have sex with them, too."

John grinned. "But you do have two hot guys living in the same house with you."

"I know, dummy," she replied with a playful smirk. "That's why I said I understand how she feels."

"So, you've changed your mind about their offer?" he asked. "And you don't mind the fact that I have two sexy women living in my house?" he asked.

Emma paused for a moment as her thoughtful expression returned. "Thinking about you and Mom having sex still makes me a little nervous," she admitted. "I bet she knows all kinds of ways to make sex feel super good that I've never even thought of. What if you like it with her more than with me?"

"Impossible," he said. "I love Mom, but you're my favorite person. I can't lie -- the thought of doing sex stuff with her is really exciting, but there's nothing we could do together that would make me less excited about being with you."

Emma beamed with happiness back at him. "I believe you," she said as she seemed to squirm in her seat, pressing her knees together as they talked. Even John, with his limited experience with women, could tell that she was still turned on.

"Would you really be okay watching me and Dad doing stuff together, too, though?"

The mere question brought to mind images of Emma and their father engaged in all kinds of sexual activities. Unlike Emma, though, the prospect didn't bother him. On the contrary, picturing the tightly wound bundle of youthful sexuality that was his little sister going at it with their mature father was more exciting than any porno that existed outside the theater of his mind.

"Honestly," he said. "I think that sounds super hot."

Emma rocked and fidgeted with embarrassment. "You do?"

John nodded. "I like seeing you happy, and I bet Dad could make you feel really happy."

"Well, when you put it that way," she mumbled as one of her hands unconsciously went up to her chest and rubbed at a hard nipple poking through her shirt. "I do like the idea of them being there with us... of sharing this all with them."

"Me, too," John agreed.

"Okay, then. Let's do it!" Emma said, pumping her fist with excitement. "Let's go fuck our parents!"

John laughed and rose up off of the bed, offering a hand to his sister. It was only then that he realized how ridiculous they both looked. Emma's pajama bottoms were soaked through with her arousal and stained with his cum. His own underwear was uncomfortably wet and cold from the few shots of cum that had filled his shorts before escaping out onto his sister's body.

"Maybe we should change first," he said.

"Yeah. Good idea. Meet me in the hallway?"

"Sounds like a plan."

Out in the hallway, John realized that he'd likely missed an opportunity to see his little sister in all her naked glory. He doubted she would have protested much had he asked to watch her get undressed. But then again, that might have led them down a path that would have further delayed their trip back downstairs to their waiting parents.

He took a quick stop into the bathroom to clean off his messy cock before heading into his bedroom. Once safely inside, he tossed his sodden pajamas into the dirty clothes hamper. He could have grabbed another pair and been done with it, but then he got another idea. Opening the bottom door of his dresser, he dug through a bunch of clothes he rarely wore before finding what he was looking for. With a satisfied smile, he donned this new garment and stepped back out into the hall.

His smile widened even further when he saw his sister wearing the same matching robe he'd chosen for himself. Ironically, it was a gift their parents had gotten them several Christmases back. John almost never found cause to wear his, but now he couldn't imagine a more perfect opportunity.

"Great minds," Emma said.

John nodded. "Ready?" he asked.

Emma nodded. "Ready."

He took her hand, and the two of them made their way back downstairs. Their parents were sitting just where their children had left them, but they looked worse for wear. Susan had been crying and was trying to compose herself as their children came downstairs. Both of them looked like defendants at a trial who knew a guilty sentence was already a foregone conclusion. Their gloomy expressions turned quickly to curiosity, though, when they saw their children dressed in the same robes they'd chosen for themselves.

"I'm sorry for storming off," Emma said.

"You don't need to apologize," Susan said. "This is all our fault. We shouldn't have sprung something like this on you. Your father and I have been talking, and we both think it's best that we try to put this behind us and have a normal Christmas together."

Emma gave an enigmatic smile. "I think it's too late for that, though."

"I know we can't just pretend like this never came up, but we... Wait. What do you mean?" Susan asked, sensing a familiar note of mischief in her daughter's tone. "What do you mean, it's too late?"

"As it turns out, you two weren't the only ones who had been fantasizing about having sex with a family member," John said, enjoying the look of confusion on his parents' faces.

"I wasn't upset that you two wanted to have sex with us," Emma continued. "I was mad that John wanted to fool around with you and not with me. But we cleared that all up, and now we're ready to play."

"Cleared it up... how?" Susan asked, her own smile growing wider and wider as she realized what this meant for the four of them.

"I'll tell you, but can we eat first? I'm starving," Emma said, relishing the opportunity to turn the tables on her parents, who had drawn out their own revelation for as long as humanly possible.

Susan rolled her eyes in exasperation. "Fine. Let's go."

The four of them made their way to the kitchen, and Susan set to work preparing breakfast for the family. While she cooked eggs and bacon and poured another cup of coffee, Emma and John took turns filling them in on everything that they'd said and done upstairs. By the time they finished their tale, both parents were practically feral with excitement.

"It sounds like we have some catching up to do," Bill said with an excited grin as stood up and brought his plate to the kitchen sink.

"Leave that," Susan said. "We'll have plenty of time to clean up later. I want to spend time with my family."

Before anyone could reply, she was on her way back to the living room. The rest of the family followed suit. John returned to his spot on the recliner, and Susan and Bill sat back down on the couch.

"As exciting as this all is," Susan said, "We should probably set some ground rules."

"Agreed," Bill replied.

Emma looked confused. "What do you mean, rules?"

"Come here," Bill said, lifting his arm and inviting his daughter to sit next to him on the couch. "I know you're new to this, but sex can be complicated. When you have sex with someone, it's more than just a physical act. You're opening yourself up to someone in a way that can get complicated really quickly. You already have some experience with how easy it is to end up with hurt feelings if you don't communicate well with your partner."

"That makes sense," Emma replied.

Susan continued. "The last thing we want is for anyone to get hurt in all of this. We have to make sure we're thinking with our heads and not with our... well, you know."

"Your mother and I have talked this through, and we have some ideas for how we can navigate this together, but let us know if there's anything either of you thinks we should add or change."

"Okay, hit us," John said.

"First," Susan said, "Your father and I feel strongly that our relationship as a family is more important than anything else. No matter what filthy things we do in the bedroom, we are still your parents and expect to be treated as such. We have a right to expect love and respect from each other, but we don't have the right to expect sex on demand. I think you'll find your father and I to be very willing sexual partners, but if either of us feels uncomfortable pressure to perform, then we'll need to re-evaluate things. Is that clear?"

"Crystal," John said.

Emma just smiled and gave a smart military salute.

"The same goes from us to you, by the way," Bill said. "If either of you don't feel comfortable with something your mother and I want, or if you're simply not in the mood, we promise to respect that."

"I'm not super worried about that one," John replied with an excited leer on his face.

"Me either," Emma added.

"You think that now," Susan said, "But you might be surprised by some of the things we have in mind. Communication and honesty are going to be incredibly important. We want regular updates about how you're both feeling -- good or bad. You're adults now, and if this is going to work, you'll have to act like adults."

"Okay, what else?" Emma asked, growing more and more impatient with the lecture.

"The last one should be obvious," Bill said. "No one. And we mean absolutely no one can know about any of this. Outside the four walls of this house, we're a boring suburban family. No suggestive remarks. No stolen touches when no one is looking. Nothing. If anyone found out about this, our lives would be ruined. You both understand that, right?"

John and Emma both gave a solemn nod.

"Is there anything either of you would like to add?" Susan asked.

"Just that I'm tired of all this talking and want to have some fun!" Emma said, eliciting smiles and laughter from the rest of the family.

"Well, what kind of fun did you have in mind?" Susan asked.

"Ooh! I know," Emma said. "Since John and I are new to sex, can you be our teachers, and we'll be the students?"

"That sounds delightful," Susan replied. Turning to Bill, she said, "Honey, will you go get the camera, please?"

"Gladly! Be right back!" With that, he zoomed out of the room, nearly slipping and falling on the hardwood floor just as his daughter had earlier that morning.

"It's for the portrait," Susan said, answering her children's unasked question. "Besides being a gift for your aunt and uncle, we thought it would be nice to take some pictures to remember our first time together as a family."

"Fine with me," John said. At that point, the Christmas portrait was the very last thing on his mind. Emma nodded in agreement.

By the time she'd finished speaking, Bill was back in the room with his camera in one hand and the tripod in the other. He took a moment to set it up in the corner of the room before rejoining Emma on the couch.

With everything in place, Susan took center stage in front of her family. She looked nervous at first, but a confident nod from her husband and a deep calming breath settled her nerves enough to continue.

"Okay students," she said, doing a silly impression of her high-school math teacher, whose stern attitude was still etched in her mind over twenty years later. "It's time for your first day of Incest 101. I understand that you both have some basic experience with male and female orgasms. Yes?"

"Yes, ma'am!" Emma replied. "But not much. I just had my first one earlier this morning."

"Hmm... Yes. I see," Susan replied as she stroked her chin in a gesture of faux thoughtfulness. "And you, son?" she asked, turning her attention to John. "We, of course, know all about what you've been doing in the shower each morning. Any experience beyond that?"

"No, ma'am," he said, grinning as he played along with their little game. "Other than me and Emma upstairs," he added.

"Yes. Very naughty," Susan replied with a wag of her finger. "And how is your knowledge of anatomy?"

"Oh, very poor!" Emma replied.

"Well, that sounds like as good a place as any to start. Why don't both of you stand up and take off those robes? Let's see those healthy young bodies of yours."

Emma and John stared first at their mom, then at each other. Despite their excitement -- or maybe because of it -- neither wanted to be the first to disrobe. Emma, in particular, felt insecure about her appearance, worrying about her small breasts and boyish figure, especially compared to their mother's more womanly figure. All of that nervousness vanished in an instant when she saw the look on her brother's face, though. John was practically salivating with anticipation at the thought of seeing his sister naked.

"On the count of three?" he asked.

Emma nodded.

"One... Two... Three..." they said in unison before dropping their robes to the floor.

Both siblings' eyes went wide with excitement as they hungrily devoured each other's nudity, marveling at the strangeness of seeing someone so familiar in such an unfamiliar way. John's body was everything Emma hoped it would be -- lean and long, with light blonde fuzz in the space between his pecs, and another trail of wispy hair that led from his belly button down to his very erect cock.

And -- Oh! That was most certainly not what she was expecting to see underneath her brother's robe. She knew from health class at school that the boy's penis went into the girl's vagina, but clearly there must have been some kind of misunderstanding. She'd tried to put a finger up inside of herself more than once, but never had much success. There was absolutely no chance that her brother's thick cock would fit inside her petite little vagina.

At least that's what her brain was telling her. The rest of her body felt hot and bothered in a way she'd never experienced before. Her nipples hardened into tight knots that ached for attention, and she felt ridiculously squishy and wet between her thighs. Every instinct in her body drew her to that thick, hard appendage poking out from between her brother's legs.

John was equally aroused by the sight of his naked sister. Her skin was pale and smooth, and, while her breasts were tiny, they fit her frame perfectly. Her nipples were a rosy shade of pink that poked outward like a pair of pencil erasers over her little mounds of flesh. Farther down, he could see the faint outline of her rib cage above her flat tummy and narrow hips. Between her legs, there was a fringe of wispy blonde curls, but with her thighs pressed tight together, he couldn't see the pink treasure beneath.

With some effort, he pulled his gaze up to her face and flashed a wolfish smile. It was so strange seeing the same cute freckled nose and toothy grin staring back at him. She looked like the perfect picture of innocent sexuality, and John felt an overwhelming desire to pounce on her, much as he had in her bedroom upstairs.

"Ahem... Very nice... Very nice..." Susan said, her voice catching in her throat as she admired her naked children.

Emma rocked on her heels, feeling bashful and more than a little intimidated by the sight of her brother's erection.

"Don't just stare, John," their mother said. "Tell her how she makes you feel."

"You're so beautiful, Em," John said, his voice heavy with love and desire. "Your body really turns me on..."

"Thanks. Me, too... for you, I mean," she mumbled awkwardly, as a deep blush spread from her cheeks and down to the tops of her petite breasts. She wasn't used to having a man staring at her with such obvious sexual hunger in his eyes, much less the man who had been the object of so many of her own sexual fantasies.

"Have you ever seen a boy's penis before?" Susan asked.

Emma shook her head. "It's really... big... and kind of scary. But I also think it's really sexy. I kind of want to touch it. Is that normal?"

"That's very normal. Especially for one as nice as your brother's," she added.

Now it was John's turn to blush.

"Would you like that, honey?" Susan asked. "Is it okay if your sister plays with your penis?"

John gulped and nodded. "Y-Yeah, please do."

A great shiver rocked through Emma's body as she stepped up close to her brother. She was a full head shorter than him, and John could hardly imagine anything more exciting than his naked sister staring up at him with her big green eyes as his cock brushed up against her tummy.

"Do I just... like, grab it?" she asked.

"Gently," Susan said. "Boys are just as sensitive down there as you are."

"Okay. Gently. Got it."

With that, Emma reached forward and brushed her hand against the length of John's cock. A desperate moan escaped his lips as he fought to keep his knees from buckling beneath him.

Emma pulled back as if she'd been bitten by a rattlesnake. "Sorry," she said with an embarrassed grin. "That felt good?"

"Very," John gasped. "Please don't stop!"

Feeling emboldened, Emma once again touched her brother's cock, this time rubbing her palm awkwardly up and down its length. John let out another excited groan and thrust his hips forward, seeking more direct pressure on his manhood.

"It feels so funny," she said to no one in particular. "So soft, but also so firm, and I love how it keeps moving around."

"They really are wonderful," Susan agreed as she stepped closer to her children, wanting to get a closer view of their incestuous explorations. "Do you want to see how to make your brother feel really good?"

"Ooh, yes, please!" Emma said with an excited nod.

"Is that okay with you, honey?" Susan asked, turning her smoky gaze on John.

"Yeah. That would be really... um... really awesome," he replied with a nervous gulp.

Despite her best efforts, Susan couldn't keep her hands from trembling as she stepped forward and pressed her body up next to her son's, suppressing a moan as she felt the heat of his naked flesh through her robe. Before she continued, though, she sought out her husband. She was about to take a step that they'd discussed many times, but she knew that sometimes things that seemed exciting in theory could feel very different in practice.

Bill was standing a few feet off, camera in hand, as he watched with rapt attention. Sensing his wife's indecision, he gave her a confident smile and a nod as he rubbed his hard cock through his robe with his free hand. Susan returned his smile, her cheeks flushing red with excitement at the utter depravity of what she was about to do.

With a renewed sense of confidence, she turned her attention back to her children. "You have the right idea, Emma. Boys are really sensitive on the underside of their penises -- right... here," she said as she guided her daughter's palm up to the ridge that separated her son's shaft from its bulbous purple head, eliciting a ragged moan from his lips.

"Ooh! I see!" Emma exclaimed as she rubbed her palm in firm little circles over her brother's glans. "Is it normal for him to leak like that?" she asked, pulling her hand away and examining the fluid that had oozed out of the tip of his penis.

"Very," Susan explained. "Have you noticed that your vagina gets all wet and slick when you're excited?"

Emma nodded. "It's like that right now," she admitted, pressing her knees together awkwardly.

"Mine, too. It's nothing to be embarrassed about," Susan replied, giving her daughter a comforting smile. "Boys get wet, too -- especially when they're really excited. It makes it easier for them to fit inside of you when it's time to fuck."

"Oh..." Emma said, an unmistakable note of disappointment in her voice.

"What's wrong, honey?" Susan asked. "Did I say something wrong?"

"No. You didn't. It's just that John's cock is really sexy, and I really want him to put it in me... but there's just no way it will fit."

Susan let out a quick bark of a laugh. "Oh, Emma... I remember thinking the same thing the first time I saw your father's cock. I was sure he would rip me in half, but I was so wrong. Your brother's cock is nice and thick, and it'll stretch you like you've never been stretched before, but in the best possible way. Your father's, too, for that matter," she added, flashing a sly smile in her husband's direction.

At the mention of her dad, Emma glanced his way but quickly averted her gaze, embarrassed by the intensity of his stare and frightened by how turned on she was by the thought of getting fucked by the man who raised her.

"There will be time to worry about that later, though," Susan said, drawing her daughter's attention back to the matter at hand. "Can I?" she asked, stepping up a bit closer in front of her son as she reached forward with a trembling hand.

Emma and John nodded as their mother wrapped her fist around the base of her son's cock. John gritted his teeth and closed his eyes as he tried to maintain control. Never in a million years would he have guessed he'd be in a situation like this, and he was quickly growing overwhelmed.

"The head of a man's cock is the most sensitive, but if you wrap your hand around him like this, you can simulate the sensation of fucking a woman's vagina." As Susan spoke, she started jacking off her son's prick, moving her fist steadily up and down in a way that felt so much better than when he did the same thing to himself. "Want to try?" Susan asked.

Emma's only reply was a quiet little coo of approval as her small, slender fingers replaced their mother's. Susan didn't remove her hand entirely, though. Instead, she kept her thumb and ring-finger wrapped around the base of John's stalk, seemingly unwilling to let go of her son's excited organ now that she'd finally gotten her hands on it.

"You have to be very gentle," Susan continued, "But men also really enjoy having their balls played with." As she spoke, her other hand drifted down between John's thighs and cupped his sack. "Ohhh yes. That's my good boy," she hissed, losing herself in her own incestuous fantasies as she rolled his nuts between her fingers. "Just relax and let us take care of you, baby. Let us make you feel soooo good."

That was all it took. Hearing his mom's sultry voice comforting him and encouraging him while she played with his balls and his sister stroked his prick was more than his virginal brain could process. His vision blurred and he lost his balance as every ounce of blood in his body seemed to surge to his cock as it swelled in Emma's hand and spurted a huge rope of cum onto his mom's robe. Emma giggled and kept stroking, sending spurt after spurt of cum flying everywhere. Some of it landed on other parts of Susan's robe while others splashed against Emma's naked skin. One dribble of spunk even sprayed against his sister's belly and slid down into the crease between her thighs, wetting the fine blonde hairs that protected the entrance to her womanhood.

A long wail of ecstasy exited his lungs as he deflated like a popped tire. Through it all, Emma kept dutifully jacking his cock, not realizing that the sensations that had been so wonderful a moment ago were quickly growing painful.

"Slow down, honey," Susan said, removing her hand from the base of John's cock and using it to halt the excited up and down motion of her daughter's fist. "Your brother will be really sensitive for a while after an orgasm like that, and we don't want to hurt him."

"Oh! Sorry!" she said, unable to hide the pride of her accomplishment.

"Mmmm s'okay," he mumbled as he collapsed down on the couch. It was only then that he noticed his father standing nearby, snapping photo after photo of the aftermath of what the three of them had done. He might have been embarrassed were it not for the endorphins still flooding his brain.

His eyes drifted back to his mom and Emma. His sister was already making a show of licking his cum off of her fingers while their father snapped close-up shots of her grinning face. Susan just stood there with an expression he'd never seen before -- something between shock and childlike glee. It reminded him a bit of pictures of himself on previous Christmas mornings after opening a long-hoped-for present.

Sensing her son's gaze snapped Susan back to the present moment. She smiled as she looked down at thick globs of milky-white fluid that clung to her otherwise clean terrycloth robe. "What a messy boy," she said, clucking her tongue and waving her finger in a mock-scolding motion.

"Sorry, Mom," he mumbled, returning her smile with a lazy one of his own.

Susan shrugged. "It's okay, sweetie. But I probably shouldn't wear this anymore. I wouldn't want any of it to rub off on the furniture."

Without another word, she untied her sash and let it fall to the floor. Despite having just cum, John's cock shot immediately back to full hardness as his eyes drank in the sight of his mother's naked body, noting all the similarities and differences between her and his sister.

Like Emma, she was slender and feminine. He wasn't surprised to see that the freckles that covered her face continued down her chest, thinning out around the top of her chest. Her breasts were quite a bit larger than her daughter's but still no more than a solid handful. Breastfeeding John and Emma had sapped them of some of their perkiness, and while they drooped a bit more than in her youth, no one would call them saggy. His eyes naturally gravitated to her puffy, pink areola and nipples that jutted out from the skin of her breasts like a pair of small, ripe plums. They were deeply swollen, and seemed to be begging to be sucked and played with.

John's gaze went lower, appreciating her soft, motherly curves. Susan kept herself in good shape, but her body still carried the marks of carrying and birthing two children. Her tummy had a slight but noticeable pooch, and her hips were thick and motherly. Far from being a turnoff, these slight imperfections served as an exciting reminder that the woman displaying herself to him was his mother -- the woman who'd given him all of her love and attention and was about to give him even more.

His gaze finally came to rest on the fiery red curls at the juncture of her thighs. Much like with Emma, he was frustrated by his inability to see more, but he could tell from the moisture on her thighs that she was very excited.

Ever since she'd started fantasizing about her son, Susan wondered whether he would find her attractive, but all of those fears dissipated in an instant as she saw the look of wonder on his face. Feeling emboldened by his hungry gaze, she did a quick pirouette, stopping halfway to arch her back and show off her full, motherly rear-end, and giving him a brief glimpse of her fur-covered mound as it poked out from between her cheeks.

"You're beautiful, Mom!"

It wasn't John who spoke but Emma. She had a big goofy grin on her face as she absorbed Susan's naked body with her eyes.

"Aw, thanks, sweetie," Susan replied, returning her daughter's smile as she leaned forward and scrunched her shoulders together, pressing her boobs together in the process.

"I think John thinks so, too," Emma said, giggling as she pointed at her brother's renewed erection. Susan licked her lips as she openly ogled her son's cock.

"She's right, Mom," he said. "You're beyond sexy."

"I'm flattered. But I think it's our turn to get some attention."

"Ooh. Yeah! Me too! What should we do?"

"Let's start by giving your brother a lesson in female anatomy," Susan replied, her heart fluttering with excitement at the look of abject lust on her son's face. "Have you ever seen a woman's pussy before, John?"

He swallowed nervously and shook his head. "Not in person, at least."

"And would you like to?"

"I bet he'd like to do more than just look," Bill said before his son could reply.

"All in good time," Susan replied with a knowing smile. Turning back to her son, she dropped to her knees and said, "First, I want you to understand how us ladies work down there. Then we can get into a more practical demonstration. Emma, why don't you take your brother's seat. And, John -- you come down here on the floor with me." Both children did as their mother asked.

Susan struggled to maintain her composure as she felt her son's warm, naked body brush lightly against her own. For his own part, John could practically smell the arousal wafting off of his mother's body, and it took every ounce of willpower he had to keep his hands off of her and focus on the task at hand.

Susan cleared her throat. "Very good. Now Emma, please spread your legs."

Emma hesitated, her pale cheeks once again turning a dark shade of scarlet at the thought of exposing herself in such a brazen way to her family. Being naked in front of them was one thing, but this felt different, somehow. His face was right there -- right up close to her most private spot, and she knew that once she opened herself to him he would see how wet and aroused she was. Having her father perched above them snapping pictures of her naked body didn't help matters. Everything about her current situation made her feel so dirty and wrong, which in turn, made her even more excited.

"Please, Emma?" John asked, gazing up at her with wide, pleading eyes. "You're so sexy, and I'm so turned on. I really want to see it... and more, if you'll let me."

There was something about the tenor of his voice that erased all of her anxiety in an instant. Her brother wanted her, and she wanted nothing more than to give herself over to him. There was nothing she wouldn't do if he asked.

"Okay," was her simple reply as her knees parted.

John, Susan, and Bill all gasped at the sight of Emma's swollen vulva. Emma's embarrassment ebbed, but only for a moment. It all came rushing back when Susan grasped her ankles and placed them up on the couch cushions on either side of her ass, making her sex as open and exposed as humanly possible.

"So beautiful..." John mumbled as he unconsciously reached down to stroke his aching cock.

"She is. Isn't she?" Susan replied. Looking up at her daughter's blushing face, Susan smiled and gently rubbed her inner thighs in a comforting motion. "You have an incredibly sexy pussy, dear. And it will look even nicer wrapped around your brother's cock."

Emma moaned, and John watched with fascination as her opening seemed to flex outward for a moment, followed by a small stream of clear fluid that dripped out of the base of her opening.

"Mmm... Yes. You like that, don't you?" Susan asked, her voice getting husky and low with her own arousal. "You like imagining your brother putting his big sexy cock up inside of your tight little hole..."

"Yes... I really do, Mommy," Emma moaned. "It's all I've wanted for soooo long..."

"Soon, darling... soon... But first, we need to give your brother a lesson in how to please a woman. Is it okay if I touch you?" Susan asked.

Emma bit her lip and nodded. "I-It's okay."

"Just tell me if anything feels uncomfortable, sweetie." Turning to face John, Susan began her lesson. "This is your sister's vulva," she said as she ran her palm over Emma's exposed sex, drawing a quiet whimper from her pursed lips. "Her vagina is the space inside where a man puts his penis. But for our purposes, we'll just call this her pussy, or if you're feeling extra naughty, her cunt."

John flinched at his mom's use of the 'C' word. He'd never once heard her say that out loud. In a way, it was surprising that she knew it at all. But the fact that she did, and that she was using it while giving a live demonstration of his sister's genitals was more exciting than anything he could have cooked up in even his wildest fantasies.

"Women's pussies are like a mouth, but they have two sets of lips," she continued, smiling slyly at the obvious effect her lesson was having on both of her children.

"What do you mean?" John asked. He could see a little strip of pink at the bottom of Emma's split, but beyond that, her pussy looked like a straight, vertical line covered in a fine layer of fuzzy blonde hair.

"These are Emma's labia majora, or her outer lips," Susan replied. As she spoke, she pinched her daughter's outer lips together and gave them a firm squeeze. They bulged outward, exposing some of the pink flesh within.

Emma let out a desperate groan and squirmed in her seat. She'd never thought of herself as a show-off -- always assuming that no one would want to look at her boyish, underdeveloped body. But being the center of attention and having her mom's hands touch her in ways she'd never experienced before was quickly unlocking something within her that she hadn't known was there.

"As you can see, your sister's outer lips are quite thick and plump. Most women enjoy having their pussy touched, squeezed, or rubbed, but the really fun stuff is inside." Releasing her hold on Emma's pussy, Susan placed a hand on either side of her daughter's vulva and spread her open for their viewing pleasure. "Yes... so lovely," she murmured, half to herself as she caught her first glimpse of her daughter's blossoming pink sex.

"Everything inside is going to be much more sensitive," Susan continued, moving so that the thumb and index finger of one hand held Emma open while the other traced a feather-light path through the gooey pink flesh of her daughter's cunt.

"OHHHHHooooooohhhhhhh..." Emma sighed, the air rushing out of her lungs in a great gust as her pussy once again flexed and released another dollop of girly cum from the impossibly tiny entrance to her vagina.

Ignoring her daughter's obvious pleasure, Susan continued her lecture while John stared in rapt fascination at what had to be the most exciting thing he'd ever seen in his life. "As you can see, your sister's labia minora -- her inner lips -- are much smaller and very pretty, if I do say so myself." As she spoke, Susan traced a line over the thin ridges of flesh that circled Emma's opening.

"You're really beautiful, Sis," John said, making a point to tear his eyes away from her exposed sex and look her in the eyes as he spoke.

Emma, who was already awash in a sea of physical sensation, practically melted at her brother's words. His approval was the only thing she truly desired, and getting it when she was so completely exposed was the most wonderful feeling she could possibly imagine.

"Thanks..." she murmured, her whole body burning with fresh desire for her brother.

"Good boy, Johnny. Did you see how she reacted to that?" Susan asked, indicating the stream of fluid that dripped from the base of Emma's opening and down to her asshole. "It can be easy to get caught up in the physical side of sex, but always remember to communicate with your partner. The quickest way to get a girl aroused is to make her feel loved and desired, and based on the way your sister's pussy is flowing, I'd guess she's feeling plenty of both. Am I right, Emma?"

"Y-Yes... I really -- really am!" Emma replied through gritted teeth as her butt squirmed around on the couch, growing more and more desperate for release.

"See how wet she is?"

Susan drew her finger once more through her daughter's slick groove and held it up for her son's inspection. "Your cock gets hard when you're aroused, but it's different for girls. Our pussies get all runny and wet and loose. It's very important that you make sure your partner is ready for you before you try to put anything inside of her. It can be very painful, otherwise."

"So does that mean Emma's ready to have sex?" he said, his voice thick with boyish excitement.

"Let's not rush things," Susan said with a patient smile. "The first time can be uncomfortable for some girls, so we want to make sure your sister is as ready as she can be before she loses her virginity."

"Oh, okay..." John grumbled.

"Don't look so glum. There's lots of things we can do to help your sister feel good. Have either of you tried oral sex?"

"You mean, like blowjobs?"

"What's a blowjob?" Emma asked, her voice laced with breathless curiosity.

Susan looked up at her husband, her eyes flashing with excitement. They'd roleplayed countless versions of this scenario as they'd worked themselves up to this moment, but neither of them were prepared for how truly innocent and inexperienced their daughter would be. Having the opportunity to teach her literally everything there was to know about sex added an unexpected element to a fantasy that was already so far beyond the limits of what either of them thought was possible.

Turning back to her daughter, she said, "A blowjob is a slang term for when a woman uses her mouth to pleasure a man's penis -- usually by licking it or sucking on it."

"Ooh. I think I'd like to try that!" Emma exclaimed before pausing for a moment, her eyebrows scrunching up in confusion. "Shouldn't it be called a suckjob, though?"

Susan and Bill chuckled. "Maybe so," she said. "But blowjobs aren't the only forms of oral sex. Boys can do it, too."

Emma's eyes went wide. "You mean suck on other boy's cocks? I'd really like to see that!"

John and Bill cast nervous glances at each other while Susan laughed. "Me too, dear, but that's not what I meant. What I was trying to say is that women can receive oral sex as well as give it. It feels absolutely wonderful to have someone's mouth licking around or even inside of your pussy. Your father always makes me cum so hard that way."

Both women turned their eyes up to Bill who stood off to the side, smiling down at the two of them with a mixture of pride and arousal. "I bet he would love to show you what he can do," Susan said, smiling wickedly as she held her husband's gaze.

"Nu-uh," Bill said, mirroring his wife's grin with an even more evil one of his own. "I want to see you do it."

"I--But... I thought we..." Susan stumbled over her words, searching for a response, but she shouldn't have been surprised.

Once the shock of seeing Craig and Sally's incestuous photos had worn off, Susan had become particularly infatuated with the images of Sally and Jenny together. She'd never considered herself a lesbian or even bisexual, but there was something about the thought of her sister-in-law touching and licking her daughter's body that tortured her with endless cycles of arousal and guilt. It wasn't long before she started wondering whether she might do the same thing with Emma one day, and once that thought entered her mind, it was impossible to dislodge. When she finally built up the courage to confess her fantasies to Bill, he fucked her like a man possessed, all the while demanding she tell him every filthy thing she wanted to do with their innocent teenage daughter.

"No holding back now, honey," Bill said. "You know what you want. Now take it."

Susan swallowed a big gulp of air and nodded. Taking a moment to center herself, she turned her attention back to her daughter. Examining and exploring her daughter's virgin cunt had been one of the most exciting experiences of her life, but she'd at least been able to hide her intentions behind the guise of teaching her son about the female body. If she took things further, there would be no doubt about what was really happening or why.

It came as a surprise to both adults when Emma spoke up. "You can if you want to, Mom," she said. "I never thought of doing something like this with a girl, but it would make me really happy if you licked me down there. You don't need to be embarrassed."

"A-Are you sure?" Susan asked, still reeling from the sudden turnabout in their roles.

Emma nodded, her eyes wide with need. "Definitely. I'm really horny, though, so please don't make me wait for it."

Susan let out a weak moan and practically fell forward into her daughter's crotch. Any pretense of teaching John how to please a woman fell right out the window as she latched her mouth over her daughter's opening and delved her tongue into her split. The taste and odor of her daughter's arousal was so unique and different from her own. She couldn't describe it, but something about her tasted fresh and new, like the morning dew on the first warm day of spring.

"OhhhhhWow!" Emma groaned. She'd loved the feeling of her brother's large body on top of hers and the rough grinding of his cock on her sensitive cunt through their pajamas, but this felt entirely different. Her mom's mouth felt so warm and wet and seemed to touch her in all the right places. A great, roiling wave of motion rocked through her, making the muscles of her tummy tremble as her crotch pressed hard against her mom's face.

"That's it, babe. Show her how long you've waited to eat our girl's cunt," Bill said, his voice husky with arousal as he snapped photo after photo of his naked wife on her knees, burying face between their daughter's thighs.

"Good?" Susan asked, coming up briefly for air.

"So good," Emma replied as she greedily pushed her mom's head back to the pulsing source of her need.

John didn't feel a bit disappointed that he wasn't getting any action, himself. He could tell from loud moans and wet slurping sounds emanating from his sister's crotch that his mom had wanted to try this for a very long time, and the way Emma's eyes rolled back in her head was a sure sign that she was enjoying herself as well. Taking his own cock in hand, he played with himself while he watched the most filthy and exciting sex show he could possibly imagine.

His eyes traveled all over his mom's naked body, appreciating the way her breasts hung beneath her chest, jiggling with the up and down motion of her head. He badly wanted to touch and squeeze them, but he hesitated, unsure how she would react.

"Go ahead, son," Bill said, sensing his son's conflict. "She'll love it."

Looking up at his dad, he was surprised to see that Bill had untied the sash of his robe, and was casually jerking himself off while enjoying the show. John had seen his father's cock before, but never in its aroused state. For reasons, he couldn't quite fathom, he couldn't take his eyes off of that long, veiny mass of flesh that looked so similar to his own. Seeing the shocked expression on his son's face, Bill just smiled and said, "Well? What are you waiting for?"

It was all the confirmation John needed. He knee-walked a few steps closer and placed a hand on his mom's bare back. Susan shivered, and he watched with fascination as goosebumps rippled across her soft, freckled skin. He'd touched his mom countless times over the course of his life, yet this felt so forbidden and exciting.

"Don't be shy, baby," Susan moaned, her voice muffled by the folds of Emma's cunt. "You can touch me anywhere you want to. I've wanted this for so long -- to feel your hands all over me -- touching me and groping me... showing me how turned on you are by your mommy's naked body. It's all for you, baby. I'm all yours... use me however you want."

John felt his balls tighten and his cock surge with excitement, but he managed to pull his hand off of his excited cock just in time to stop himself from coming. He didn't need another reminder that what the four of them were doing was filthy and wrong, but hearing his mom talk that way -- giving him permission to explore her body to his heart's desire -- made the reality of their situation almost too vivid and exciting to handle.

Keeping one hand firmly planted on Susan's back, he reached underneath her with the other, grasping one of her hanging tits in the palm of his hand. He'd never felt a woman's breast, but even without a point of comparison, he knew that his mom's were absolutely perfect. He tested their weight and firmness, giving them a gentle squeeze and finding the soft, pliability of her flesh to be strangely exciting.

Susan let out a desperate moan as her whole body roiled with arousal at her son's touch. Keeping her mouth planted on Emma's cunt, she sagged downward, pushing her breast more firmly into John's palm.

His fingers squeezed and toyed with her, eventually zeroing in on her puffy, red areola which he took between his thumb and forefinger and squeezed. Susan shrieked as a small orgasm rocked through her body. Not realizing what was happening, John pulled his hand away, afraid he'd hurt her.

"No! Puh-Please! Back -- Put it back! Don't stop!" she pleaded. "Feels S-So Guh-guh-goood..."

Happy to comply, John once again reached down and started pinching and pulling on his mom's nipple. The angle was awkward, but eventually he reached farther underneath, grasping her other tit and giving it the same treatment. He felt a giddy sense of disbelief as he played and pulled with her rubbery nipples, marveling at the way she sighed and moaned in reaction to his exploratory touches.

As he groped his mom's tits, his other hand stroked her back, first in slow circles, surprised by how erotic it was to feel the muscles of her back arch and release with the motions of her body. Eventually, his motions grew wider, giving her firm strokes from the nape of her neck down to her tail-bone.

Finally releasing her breasts, he scooted behind her. There was something else he wanted to see and touch. Freed from his nervousness and hesitation, he moved behind his mother and took the cheeks of her ass in his hand and spread them wide, exposing her hairy asshole and cunt to his excited gaze.

He marveled at just how different his mom's vulva looked from Emma's petite opening. Susan's inner lips were thicker and spilled out from her outer lips, and her pubic hair was dense and wiry -- a stark contrast to the wispy blonde fuzz that covered his sister's sex. It was the pussy of a grown woman -- not a teenage girl. One that was ready to take a man's cock at a moment's notice.

One thing that wasn't different at all was her visible arousal. A long strand of clear fluid dangled from her opening and clung to her inner thigh. Her whole crotch seemed to be soaked with the stuff. If he didn't already know how excited she was, he might have thought she'd peed herself.

Feeling his boyish curiosity taking over, John started to explore. He began by combing his fingers through her pubic hair, spreading it outward to get an unobstructed view of her wet slit. Remembering what his mom had done to Emma earlier, he placed his thumbs on opposite sides of her opening and spread her wide. He stared with wide-eyed fascination into his mom's pink, pulsing depths. Almost without realizing it, his thumbs slid inward, the added leverage giving him an even more lurid view of his mom's glistening insides.

"Oh! That's... um... okay..." Susan said, her body tensing in momentary embarrassment at being so completely exposed to her son.

John's hands snapped away like he'd touched a hot stove.

"No! It's okay!" she said, turning to rest her cheek on Emma's wet mound as she spoke. "I just wasn't expecting you to be so... intimate. Go ahead and explore -- learn all about a woman's insides. It's what I'm here for."

With a fresh surge of confidence, John once again slid his thumbs into his mom's slit and took another look inside of her. He'd never seen anything quite so enticing as the slimy pink flesh of his mom's vagina as it seemed to swell and recede with her strained breathing.

"Do you see that little hole deep inside of me? It looks a little like a donut," Susan asked, once again adopting her teacher persona.

"Yeah. I think so." John replied. He examined it closely, marveling at the mysteries of the female body. It was covered in what looked like a thick, milky fluid that, if he had to guess, was coming out of the puckered dimple at its center. "What is it?" he asked.

"That's my cervix, baby -- the entrance to my womb. It's where you grew inside of me."

"Can I touch it?" he asked, his voice shaky with unnatural lust.

"Yes. Gently, though. Too much pressure there can be painful."

Keeping one thumb hooked inside of her opening, he removed the other for a moment, only to replace it a second later with his index and middle finger, pushing them deep into his mother's body until he felt something firm and smooth. "Is that it?" he asked, mesmerized by the utter strangeness of feeling such an intimate part of her anatomy.

"Mmm... yeah, that's it, John. You're touching the spot where you were born, baby. And it's where your semen will go when you cum inside of me."

"Wow..." he mumbled as he carefully explored his mom's most forbidden depths.

The sensations coursing through Susan's body were overwhelming on their own, but hearing the awe in her son's voice as he touched her broke something in her brain. She'd never felt more filthy and whorish, or more loved. Those two competing emotions fought for dominance before somehow coalescing into an acceptance that two things could be true at once. She loved her son dearly and she was a good mother to him. She was also a tramp. A slut. A fallen woman who would let him use her body however he liked.

This surprising revelation was accompanied by an equally surprising orgasm that quickly washed away any conception of herself as a being separate from the fingers penetrating her sex. "Unnnnghhhh... Oh god... Oh shit... OH FUCK!" she shrieked, as her inner muscles pulsed and a stream of fluid poured out of her, soaking her son's hand and the floor below. With her head turned to the side, she caught her husband's excited gaze.

"He made me cum... Our boy -- my son -- just made me cum so fucking hard!" she moaned.

Tearing his eyes away from his mom's crotch, John looked up at his father, who was jerking himself off while smiling down at his wife. He knew his parents loved each other deeply, but he couldn't remember a time when he'd seen such adoration on his father's face.

"Keep going, baby," she begged. "Touch me. Squeeze me. Finger the shit out of me. I don't care what you do, just keep doing it!"

John was happy to do whatever she asked, especially if that meant freely exploring her dripping hole. Not knowing exactly what he was doing, he ran his fingers back and forth in her wet passage, surprised at how quickly and easily his index and middle finger slid inside of her.

"Mmmmmmyeah. That's it," Susan grunted. "Fuck Mommy's hot cunt, baby. Really get in there deep."

He could hardly believe the filth that was spewing out of his mom's mouth. It was like she'd been possessed by some kind of incestuous demon. But of course, she hadn't. This was the same loving mother he'd always known, and it excited him beyond belief knowing that these desires had been bubbling beneath the surface for who knows how long, just waiting to boil over.

Following her instructions, he started ramming his fingers in and out of her hole, curling them this way and that, trying desperately to touch every part of her. Susan went wild, her hips bucking like a bronco as she went back to work, lapping at Emma's cunt. He couldn't believe how slimy and hot she felt as her fluids poured out around his fingers or how it felt when her hole tightened, gripping him as it pulsed and spasmed in response to his every motion. It was impossible not to imagine how amazing her slick hole would feel around his cock. The thought made his head spin.

"Does it feel good, John?" Emma asked, drawing his eyes upward.

He'd been so focused on his mom that he'd barely paid any attention to his sister. If she was jealous, though, she wasn't showing it.

John grinned and nodded. "She feels really amazing."

"Mom's tongue feels really sexy on my pussy. You should do it to her -- OOH! I think she likes that idea," Emma added with a happy gasp at whatever Susan had done between her legs.

Feeling bold, John grinned back at her, and said, "I will if you give Dad one of those suckjobs you were talking about."

Emma, who had been all laughter and happiness moments ago, suddenly grew quiet, making John worry he'd overstepped. Craning her head, she seemed to truly notice her father's hard penis for the first time.

Sensing her nervousness, Bill said, "Only if you want to, sweetie. But I would really like it," he added, taking a step forward as he kept jerking himself off to the sight of his loving family licking, sucking, and touching each other's naked bodies.

"I want to, but I don't know how," Emma said.

"You can just lick it or put it in your mouth a little bit. Whatever feels good to you."

Emma blushed and gave a shy nod. "Okay. I'd like that, I think."

Time seemed to stand still as Bill took another step forward, putting his hard cock within inches of his daughter's mouth. The contrast between his masculine prick and Emma's innocent, girlish features set a new bar for the filthiest thing John had witnessed, and even Susan couldn't help but pause her own oral activities to watch what came next.

With a demure smile, Emma reached forward and grasped her father's penis, letting out a quiet gasp as it bucked and jerked in her grasp. Bill's lusty groan was more overt. Taking her actions as permission to push things further, he pushed his crotch forward, pressing the tip against her delicate lips. Emma didn't immediately open her mouth, but he wasn't deterred. Using his hips for leverage, he traced the contours of her mouth with the leaky tip of his cock.

Emma's heart raced with a swirl of confusing emotions. This felt so filthy and wrong -- somehow way more forbidden than her mom's own mouth licking between her legs. Yet that wrongness made it so much more exciting. The very concept of a man putting his penis in a woman's mouth had never crossed her mind until just a moment ago, but now that it had, she could hardly imagine anything more exciting. Doing something like that for her daddy, who she loved so much, added an extra layer to her arousal that was almost too much to take.

Smiling up at him with her big green eyes, her lips parted, and she gave the head of Bill's cock a wet, open-mouthed kiss.

"Oh fuck yeah, baby," Bill moaned. "That feels so nice... My sweet little girl is making me feel so good."

Emma smiled through the corners of her mouth, her heart fluttering with pride at the effect she was having on her dad.

"Stroke him while you kiss it. Just like I taught you," Susan said from beneath them.

"Like this?" she asked, keeping her eyes locked with her father while giving him a few experimental strokes.

"You don't have to be so gentle, sweetie," he replied, placing his hand over her fist and guiding her to jerk him off harder and faster. "Mmmm yeah. That's it," he groaned as she got into the rhythm.

Emma let her father's cock penetrate her lips once again while she jerked off the base of his shaft. This time, she took him in deeper, once again surprising herself with how much she enjoyed feeling his warm girth filling her mouth.

"Mmmm... You taste so good, Daddy!" she exclaimed before diving back for more, this time swirling her tongue around the tip of his cock.

"You're doing such a good job, Emma," he said through panting breaths as he reached down and ran his palm lovingly through her hair. "Keep going just like that and I'll cum just for you. Would you like that? Would you like to taste your daddy's hot cum? To feel it filling up your pretty little mouth?"

Emma's eyes grew wide and desperate as she gave a firm nod and a murmured, "Mmmhmm!"

To John's surprise, his father turned his attention away from Emma and toward him. "Don't you have something you should be doing?" he asked. "And you, too, honey," he said to his wife. "That pretty pussy isn't going to eat itself."

John's heart skipped a beat as he remembered that he'd made a deal with his sister and still hadn't fulfilled his end of the bargain. As much as he hated to tear his eyes away from the mouth-watering sight of his sister sucking cock for the very first time, the prospect of giving his mom the same treatment was too exciting to put off for long.

Dropping to his knees, he took in another up-close and personal view of his mom's drooling hole. Her plump inner lips looked delicious as they splayed outward, giving him an enticing glimpse into the dark red interior of her sex. He didn't spare a thought for doing anything the 'right' way. He was too far gone for that. After taking a heady whiff of her feminine arousal, he buried his face between the cheeks of her ass and started lapping away at her crotch like a pig at the trough.

The effect was immediate. Susan let out a muffled shriek and bore down hard on her son's face, pushing her crotch more forcefully against his insistent tongue. Her juices smeared all over his cheeks and chin. The taste excited him in ways his logical brain couldn't process. Her flavor was rich and salty, and somehow instantly recognizable as belonging to his mom despite having never tasted it before. He couldn't get enough, which was good because there seemed to be no end to the amount of fluid that poured out of her.

Positioned as he was behind her, the tip of John's nose rested right at the puckered entrance to her ass. To his surprise, he didn't mind this one bit. On the contrary, his boyish enthusiasm led his tongue higher, until he was swiping his tongue over and around her wrinkled rear passage.

"Oh, you naughty boy..." Susan grunted. "Yesssss... lick Mommy's dirty asshole. It feels so nice, baby. You're making me feel sooooo nice..."

John happily complied, using his lips and tongue to devour every inch of his mom's hindquarters, moving back and forth between her ass and her pussy as his instincts dictated.

Sounds from above reminded him that there was more to enjoy than his mom's pussy. With his mouth planted between her legs, he still had a clear view of the upper half of Emma's body as she sucked their dad's dick.

Bill was beyond comprehensible speech, mumbling compliments and encouragements to his daughter as she slid his dick in and out of her mouth. He kept one hand on the top of her head, guiding her movements as he reached down with the other to pinch and pull on her pointy little nipples. Emma writhed and moaned between her parents, her focus repeatedly drawn back and forth between her dad's cock sliding in and out of her mouth, and her mom's tongue running laps around her clit.

Eventually, it got to be too much to take. A quiet, muffled whine emanated from deep within her that grew louder and louder with each passing moment until she was practically screaming through the space between her lips and Bill's cock. Her whole body felt feverish and tingly, especially her pussy, which was starting to feel that same sense of impending release.

Unable to hold on any longer, she let her dad's cock fall free from her lips and released a pathetic wail, her hips bucking hard into her mom's mouth as she started seizing, her arms and legs flailing with wild abandon. She whimpered and groaned, utterly lost to the world as overwhelming pleasure washed through her. Suddenly, as if a switch flipped, her mom's tongue was too much, each swipe feeling like a bolt of lightning flashing through her whole body.

"Ah! M-Mom... It's t-t-too m-much... T-Too much!" she shrieked as she finally regained enough control of her limbs to push her mom's face away from her crotch while the rest of her body bucked and heaved through an earth-shattering orgasm.

Bill stared dumbfounded down at his innocent daughter, rocked by the most indecent pleasure imaginable. The sight of her pink pussy, so swollen and drenched with her arousal and his wife's saliva, was more than he could take.

"Emma! I'm gonna cum! Gonna cum all over you, baby!" he said, his voice frantic and a little afraid of how she might react.

She heard him, but it was like he was calling out to her from the other end of a long tunnel. Her next conscious thought was that she was wet -- that someone must have spilled a glass of warm water on her. It didn't make any sense, until her own orgasm started fading enough for her to be aware of the crazed look on her father's face as thick wads of cum poured out of the tip of his penis, drenching her face and her chest with his spend. She opened wide, wanting more than anything to taste her dad's cum, and sure enough, he pushed the end of his cock between her lips, letting the last few spurts of semen splash against her tongue.

The whole tableau was so far beyond anything either of the parents had imagined in their wildest fantasies, and the sight of her husband's cum painting their innocent young daughter's pale white skin combined with her son's insistent lapping between her legs sent Susan over the edge of another powerful orgasm of her own.

"Oh fuck... ohhhhh fuck... OHHHHHFFUUUUCK!" she yelled as a great tremor ripped through her legs and a gush of hot fluid shot out of her pussy and directly into her son's eager mouth.

He wondered whether his mom was peeing, but quickly decided that it didn't matter. There was nothing she could do, no secret of her body that wouldn't thrill him. Planting his mouth right over her opening, he sucked on her lips, drawing more moisture into his mouth and swallowing it down before delving his tongue deep inside of her sex.

Susan let out another shriek as her elbows collapsed beneath her and she buried her face in the carpet. Her son's tongue was inside of her body. The boy she'd birthed was licking and sucking on the very pussy he'd emerged from 19 years ago. She'd imagined this moment over and over again, wondering how he would react to her wanton desires. Now those doubts were gone, and only deep, satisfying pleasure remained. She never wanted it to end.

But of course, it had to.

After a moment or two, the sexual mania driving their actions finally crested and waned, leaving them looking like they'd just completed a triathlon. Bill sat heavily on the couch next to his daughter, watching with dumb fascination as she lazily drew gobs of his cum from her chest and brought them up to her mouth.

"I can't believe no one told me how delicious this stuff is," she mused to no one in particular.

"Me either," John said as he guided some of his mom's ejaculate into his own mouth, letting the flavor settle on his tongue before he swallowed it down.

Susan turned around and sat on the carpet in front of her son, her cheeks flushing with embarrassment when she saw what a mess she'd made on her son's face. "You made me squirt," she said.

John cocked his head and gave her a questioning look.

"When your mom gets really excited, she cums like a boy," Bill said, sensing the question on his son's lips.

"I'm sorry, honey. I should have warned you," Susan added. "It doesn't happen all the time, but feeling your mouth on me like that... I just couldn't hold back."

"Don't apologize, Mom," John replied. "It was so hot. Do you think that will happen when we have sex, too?"

"God, I hope so," she said, her eyes falling naturally down to her son's crotch as she imagined her son's beautiful cock sliding inside of her.

It was only then that she realized that her son's cock was still rock-hard. She smiled and remembered what Sally told her about boys their age. They were easily overexcited and quick to lose control, but they could go over and over again. Apparently John was no exception.

"Come here, sweet boy," she said with a loving smile. "Your mouth made me feel so good. Now let me use mine, too."

John didn't need to be told twice. His mom looked sexy as hell, lounging in front of him, her legs spread wide, not caring at all how immodest she looked with her soaked cunt parted between her legs and her breasts and belly drenched in sweat. She could have told him to jump off of a bridge and he'd do it. Rising on wobbling legs, he stepped up to his mom as she sat up straight and took hold of his prick.

Looking up at him with motherly concern, she said, "You don't need to be gentle with me or take it slow. You'll feel like you want to thrust your cock into me, and that's okay. Just do whatever feels good."

"Are you sure?" John asked, already knowing the answer but not wanting to seem too eager.

Susan nodded. "Very. You have no idea how many times I've thought about this -- how many times I've imagined having your sexy cock in my mouth -- fucking my face. Just grab my hair and use me, baby. And when you need to cum, just let it go. I want to taste it all."

Hearing the raw lust and utter sincerity in his mom's voice almost set him off without a touch. "I love you, Mom," he said. "I love you so fucking much."

He'd wanted to say something sexy and exciting, but as soon as the words left his mouth, he knew they'd been right. Susan sniffed, holding back an emotional outburst and said, "I love you too, my sweet boy. Now let me take care of that gorgeous cock of yours."

Susan opened her mouth wide, and John leaned forward, pressing his prick as deep into her mouth as he could. His mom looked up at him with wide lustful eyes, grabbed the cheeks of his ass, and pulled him in deeper, until he could feel the head of his prick sliding into the back of her throat. She made a happy gurgling sound and winked up at him, giving as clear a signal as she could that she was enjoying herself.

What happened next wasn't sweet or romantic. John immediately understood what his mom meant when she said he'd want to thrust into her mouth, and he was glad she'd given him permission in advance. He felt overcome by a selfish urge to possess her, to use her, to make her understand that her mouth existed solely as a receptacle for his cum. Doing just as she asked, he grabbed two handfuls of her curly red hair and pushed his cock even deeper into her throat, groaning desperately at the most sublime pleasure he'd ever experienced.

His mom's eyes drooped happily as he withdrew and gave one more experimental thrust. After that, he was off to the races. Throwing caution to the wind, he rhythmically pumped his cock in and out of her sucking mouth. Each time he pulled out, Susan sucked deep, dragging the length of her tongue against the spongy head of his cock. When he thrust back inside, she swallowed repeatedly, milking him with the muscles of her throat. The sensation was so much more intense than he'd imagined it would be.

He fucked her face with an animalistic intensity, insensible to everything but the pleasure coursing through his cock and the wet, slurping sounds of his mom's sucking mouth. Movement out of the corner of his eye drew his attention, and he smiled as he watched Emma and their dad lazily making out on the couch. His sister looked so small and innocent compared to their father's mature, masculine body, emphasizing the taboo nature of their actions.

Something about the sight of them set him off, and he turned his attention back to his mom's pretty face, stunned by how gorgeous she looked as her freckled cheeks hollowed out around his excited prick.

"Mmmm Fuck! I love fucking your mouth, Mom!" he exclaimed. "You're gonna make me cum!"

Susan intensified her efforts. She couldn't wait to taste his hot sperm straight from the source. Moments later, she felt his balls contract and prepared herself for his outpouring.

He thrust once more into her mouth and held himself there, spurting again and again, loving the feeling of her throat rhythmically gripping and releasing the head of his cock as she swallowed his cum. When he was finished, she pulled back, making a noticeable popping sound as her lips broke contact.

Susan sighed contentedly, leaned back, and smiled up at her son. The actual act of sucking him off and drinking his cum was so much more satisfying than she imagined. It wasn't just the sexual thrill of sucking cock. She loved taking care of her children, and seeing the relief on her son's face made her feel like a good mom, even if what she'd just done was very, very bad.

"How was that for a first blowjob?" she asked, staring up at him, her curly red hair disheveled, and her lips and chin were dripping with saliva. Although she'd done her best to swallow it all, a few strands of her son's cum leaked out of the corners of her mouth. She'd become her son's cum-slut and absolutely looked the part.

John grinned down at her. "It was amazing. You're the best, Mom."

"It was lovely for me, too," she replied, demurring at the compliment. "So no more jerking off in the shower, okay? If you need relief, come to Mommy. I'll take care of you."

There was something about the way she said it that struck him. She wasn't just trying to titillate him -- though that was certainly part of it. Her voice had the same motherly tone she might have used when offering to clean his laundry or make his favorite meal for dinner. They may be sexual partners, but she was still his mom. What they'd done hadn't changed their relationship -- only added to it in new and wonderful ways. He couldn't remember ever feeling more connected to her.

Without sparing a thought to where her mouth had just been, he dropped to the floor, crawled up into her arms, and kissed her full on the lips. Susan let out a happy moan and opened her mouth, welcoming his eager tongue.

Like Emma and Bill on the couch above, mother and son sat next to each other, kissing and stroking each other's naked bodies. All the heat and passion was gone, but their love remained. John had kissed a few girls, but not like this, and his mom guided his movements, giving him quiet moans of approval and words of encouragement when he did things she liked.

Eventually the pairs shifted, and Susan rejoined her husband on the couch while Emma took a seat in her brother's lap. She loved her daddy, but there was something about being in her brother's arms that just felt so comfortable and right.

There was a note of hesitation in Susan and Bill's embrace as they searched each other's faces for any hint of jealousy or regret over their actions. They weren't blind to the possible repercutions of fooling around with their children. Both of them had worried endlessly about the consequences, both for Emma and John and for their own relationship, each of them assuring the other that taking this step would be worth the risk while knowing inside that there was no way to truly know how they'd feel until they'd actually gone through with it.

"Are you okay?" Susan asked.

Bill nodded. "You?"

"Better than okay," she replied, her expression brightening as her anxiety eased. "I thought I knew what it would be like... how I would feel... but I had no idea."

"I know. Seeing you down there with our kids, loving on them like that... you looked so beautiful."

Susan melted under her husband's adoring gaze, hardly believing that she'd ever felt the spark going out of their relationship. She's never been more in love with the man she'd married.

"I love you so much, Bill," she said, choking back tears as she nuzzled her face into his hairy chest and letting out a happy moan when he wrapped his arms around her.

Bill let out a happy sigh as he felt his wife's naked body press up against his own. What had happened with his daughter had been, in some ways, the most thrilling and perverse act of his life, but nothing could match the feeling of intimacy and connection he felt with his wife. He'd been skeptical when Sally and Craig told them incest had improved their marriage, but now he understood. Sex with other people only emphasized the intensity of his feelings for his wife.

Getting her emotions back in check, Susan sat up straight and gave her husband another elated smile. "How about you two?" she asked, turning her attention to John and Emma, who were still making out, lost in their own private world.

"I'm good. Real good," John replied, letting out a satisfied groan as he stretched his arms out above his head.

"Boys," Susan replied, rolling her eyes at her son's typically horny behavior. "How about you, Emma?"

Emma hesitated, as if she was choosing her words carefully. "It felt really sexy having you lick my pussy, and I really liked sucking your cock, Daddy," she said, heat rising to her cheeks at the strangeness of saying something so nasty out loud. "But... is all of this really okay?" Casting a shy glance back at her brother, she said, "I've fantasized about doing things with John for a long time, but I always knew those feelings were wrong. In some ways, I still feel that way, but it also feels really right, too. It's just confusing, I guess..."

There was a momentary pause as Susan and Bill shared another look, silently negotiating who would answer.

"We know how you feel, sweetie," Bill finally said. "Your mom and I tortured ourselves for weeks over the same question. We worried that wanting to be with the two of you like this made us terrible people and even worse parents."

"But feeling that way didn't make us want you any less," Susan added. "If anything, knowing how forbidden our desires were just made them even harder to ignore. And actually going through with them has felt just as nasty and wrong as I expected... but it also feels kind of natural, too. Right? Almost like this was how our family was always meant to be. I mean, when was the last time the four of us just sat together and talked like this? Can something that brought us closer really be wrong?"

A weight seemed to lift off of Emma's shoulders as her mom spoke. "That makes sense. I always thought my fantasies about John were sick. And now... well, I guess they still are," she said as an impish smile spread across her face. "But maybe that doesn't matter -- even if no one else would understand."

"I wouldn't be so confident on that last point," Bill said. "This is all new to us, but Sally and Craig say these relationships aren't as uncommon as you might think. They know several incestuous families who join them for sex parties on a regular basis. Apparently, there's even some kind of summer camp for families like ours that they've attended for years."

"Wait, so they spend all summer having sex with each other out in the open whenever they want to?" Emma asked, her eyes wide with surprise and wonder.

"I think that's the idea."

"Wild," John mumbled, his eyes glazing over as he imagined the possibilities.

"Can we go this summer, too?" Emma asked, squirming around in her brother's lap as images of incestuous hedonism drifted through her mind.

Susan and Bill laughed. "One step at a time, sweetie. We haven't even opened our Christmas presents yet, and you're already thinking about summer vacation."

"Oh, right! Presents! When can we open them?" she asked as her eager gaze shifted to the pile of unwrapped packages piled high under the tree.

"Why don't we get cleaned up first," Bill suggested, smiling affectionately as he stood up from the couch and stretched his limbs. "Then we can do Christmas before getting back to the real fun."

"Sounds like a plan," Susan said as she rose from her comfy spot on the couch. "We could all meet up back down here after we've showered. Or..."

"Or what?" John asked, sensing enticing possibilities in his mom's unfinished sentence.

"Or... we could wash up together. It might be a tight fit, but our shower is probably big enough to fit all four of us."

"I'm in!" John eagerly replied, his cock already hardening at the prospect of soaping up his mom's naked body.

"Race you!" Emma shouted as she scrambled out of her brother's lap and darted up the stairs, her skinny legs all akimbo, heedless of anything but her own excitement. "Best. Christmas. Ever!" she shouted, her voice echoing throughout the house.

By the time John, Bill, and Susan made it upstairs, Emma was already under the spray, warm water glistening as it flowed over her lithe, girlish body. "What are you waiting for?" she asked, seeming not to realize just how sexy she looked to the other members of her family.

Without another word, the rest of them piled in. Susan and Bill's hot-tub style bath occupied the corner of their large bathroom. Two shower heads pointed from opposite directions, so no one had to take turns with the water. Even with that extra space, it was a tight fit for four, but that was more than okay with them.

John immediately glommed onto his sister's body, paying close attention to her small breasts and sensitive nipples. Having free access to explore a woman's naked body -- even his sister's small, underdeveloped one was beyond exciting. He loved the way she sighed and leaned into him every time he ran his palms over her rubbery nipples.

Bill did the same with his wife, soaping her breasts, belly, and matted pubic hair with practiced ease.

Both couples stole glances at the other, silently reveling in the strange unreality of being so naked and free with the closest members of their family.

Giving her husband a playful wink, Susan broke away from him and joined their son and daughter, plastering her naked body against Emma's back and sliding her slippery tits up and down against her daughter's flesh, abandoning all pretense of getting clean.

Emma shivered and turned around, giggling as her smaller breasts squished up against her mom's more curvaceous rack. "You're so naughty, Mom," she said. "I know some girls like other girls, but I didn't realize you were one of them."

"Me either," Susan said, her voice breathy and low. "But ever since I saw those pictures, I can't stop picturing my hands and mouth all over your sexy little body."

"I'm all yours, Mommy," Emma replied, tilting her chin back and offering her neck and breasts to her mom's hungry mouth.

Susan let out a ravenous moan as she kissed her daughter, sucking her plump lips between her own before moving lower, planting kisses over her chin and down her long slender neck as the water from the showerhead flowed over them. Eventually, her mouth made its way down to her daughter's nipples and hungrily sucked one between her lips, flicking her tongue out at the hard little nubbin.

"That tickles!" Emma giggled as she bashfully turned aside, leaving Susan looking desperate and unfulfilled.

"Sorry, sweetie. I guess I got a little carried away," she said, her cheeks burning with embarrassment.

"It's okay. It just surprised me is all. I never thought of having someone suck on my nipples before. You can try again if you want to."

"Are you sure? I can stop if it makes you uncomfortable," Susan said, trying to maintain a neutral tone despite her overwhelming desire to suck on her daughter's tits.

Emma just grinned and pulled her shoulders back, silently inviting her mom to feast on the pair of little lumps on her chest. A delirious moan escaped Susan's lips as she bent forward and once again latched on to Emma's nipple. She took a different tack this time. Instead of teasing with her tongue, she sucked hard on the little knob of malleable flesh, drawing it between her lips, catching it between her teeth and biting down -- not enough to hurt but enough that Emma could feel it.

"Ooh! That feels really nice, Mommy," Emma cooed as she cradled Susan's head in her arms.

Unable to resist the growing call of her own depraved arousal, Susan reached between her legs with both hands and started fucking herself, shoving the middle and ring finger of one hand into her cunt and using the other to stimulate her clit.

John and Bill had abandoned any pretense of getting clean as they watched the conservative housewife they thought they knew so well give herself over to her most taboo desires. Both men casually stroked their hard cocks, hoping not to do anything that would interrupt the lewd scene playing out before them.

Of course, the status quo couldn't last for long. Sensing motion out of the corner of her eye, Emma turned to face her brother and father. She wasn't surprised to see what they were doing, but it was still jarring to see the two men she knew best standing naked in front of her, openly masturbating.

"Do boys usually like watching girls do sexy things together?" she asked to no one in particular.

"Most do," Susan replied, pulling away from her nipple with a wet pop.

"But why?"

"It's just basic math," John explained. "Women are sexy. Two women doing sexy things together is even more sexy. Right, Dad?"

"That's pretty much the long and short of it," Bill agreed. "And your mom and sister happen to be the sexiest women alive."

Emma smiled at the compliment even as her nose scrunched up and her eyebrows narrowed in deeper thought.

"I guess that makes sense. I think you two are sexy, too, so can I see you and Dad do stuff together?" she asked.

John and Bill's hands froze on their cocks. They turned to face each other, their expressions stricken with discomfort before turning back to Emma and Susan, who had stopped suckling on her daughter's tits to see how the men would react.

"What? Did I say something wrong?" Emma asked, worried that she'd ruined the moment somehow.

"No, honey," Susan said. "You didn't. But... Your brother left something out in his explanation. You see, most boys think girls having sex with girls is natural -- that it's all just girly, feminine fun."

"Isn't it?" Emma asked.

"It can be! But boys don't think of it that way when it comes to being sexy with other boys. Kissing, touching, or even having sex with another man would be a very serious and very dangerous threat to their all-important sense of manliness. Isn't that right, boys?" Susan asked, her voice laced with playful sarcasm as she turned an accusing smile on her husband and son.

John and Bill opened their mouths to reply, but nothing came out. What could they say? As much as they hated to admit it, they both knew she had a point.

Emma frowned. "So John and Dad won't do sexy stuff together? Don't they know how fun it is to give blowjobs?"

"You'll have to ask them," Susan replied, her smile widening as her daughter unintentionally backed both men into doing something she also found highly arousing.

"I'm not opposed to other people doing it if they want to," John said. "It's just that I'm not gay."

"I'm not gay either," Susan replied, standing up straight and crossing her arms under her naked breasts. "But I can recognize a sexy girl when I see one, and I'm not about to let some social hangups get in the way of a good time."

"So you really won't?" Emma said, pouting with the big puppy-dog eyes she'd used to get her way countless times in the past. "It would be soooo hot to watch. Plus, you got to watch me and Mom!"

"But you and Mom like doing that kind of thing," John protested.

"And you're sure you don't?" Susan countered. "Your sister's right. You're both sexy guys, and sucking cock is a lot of fun. How do you know you don't like it if you haven't tried it?"

John and Bill turned to each other yet again, silently asking each other how the tables had so thoroughly turned on them in such a brief space of time. Both men shrugged and turned back to Emma and Susan.

"We're not getting out of this, are we?" Bill asked.

Susan tried to keep her victorious smile in check, but her excitement was obvious. "We can't force you. But seeing my handsome son go down on his dad would get me really excited, and it sounds like Emma feels the same way."

"I do," Emma confirmed.

"I have such a hard time controlling myself when I get that way. I bet there's almost nothing we'd say no to after seeing something like that. Isn't that right, Emma?"

"It sure is!"

The quid pro quo couldn't have been more clear, and despite his anxiety over what they were suggesting, John couldn't help but imagine the filthy things he might ask in return. He even allowed himself to consider the possibility that sex with his dad might actually be a little bit fun. If nothing else, he liked the thought of doing something that so obviously excited the two women he loved most in the world. Another quick glance at his father confirmed his thoughts ran in a similar direction.

"So what?" Bill asked. "Do we just start sucking each other's dicks?"

"No," Susan replied. "Build up to it a bit. Soap each other up. Touch each other's bodies. Kiss a little. You know -- put on a show. I promise we'll make it worth your while."

"Okay, sure," Bill replied, the faint hint of a smile forming on his face as he saw the excitement on his wife's face. "You ready, son?"

"Yeah. I think so," John replied.

Both men stood awkwardly in the shower spray, each waiting for the other to make the first move.

"Can I --"

"Should I --"

"Oh, sorry..."

"It's okay. I just --"

They knew each other as well as anyone could, but suddenly, they felt like strangers walking on eggshells, terrified of causing offense. Finally, Bill squirted some body wash into his palm and started rubbing it onto his son's chest. John froze, holding his breath like he was preparing for an invasive procedure at the doctor's office. It was almost surprising when he found that his father's touch wasn't at all unpleasant. His hands were bigger, and his motions were less delicate, but that wasn't necessarily a bad thing. If not for his instinctive revulsion at being touched this way by another man, he might have acknowledged that it felt pretty good.

Bill, too, was surprised by how much he enjoyed touching his son's body. John was tall and lanky, with just a small patch of wispy hair between his pecs. No one would accuse him of being girlish, but he couldn't pretend like he didn't know why his wife and daughter found him so sexy.

Both men went through similar experiences but in reverse when John copied his father's actions, rubbing a dollop of soap into his father's hairy chest.

Excited moaning momentarily pulled them out of their private mental battle. Emma and Susan were both perched on the ledge of the tub, resting their backs against the tile walls with their legs spread wide, watching them with unspeakable lust while rubbing at their slits.

"Keep going," Susan grunted. "Don't stop."

They did as she asked, continuing to soap each other's bodies. When their chests were fully clean, they did each other's arms and backs, carefully avoiding anything below the belt line or above the neck.

"Kiss!" Emma called out, reveling in her ability to make her father and brother do whatever she wanted -- a power rarely afforded to the youngest member of the family.

John sighed, knowing this moment would come. His eyes traveled up to meet his father's nervous gaze. Bill was several inches taller than him and quite a bit more muscular. He knew his father would never force him to do anything he didn't want to do, but he still felt strangely vulnerable standing naked next to this much larger man. Part of him wondered whether this was how Emma felt when they'd made out earlier that morning. An even smaller voice in his brain asked whether being helpless -- surrendering himself to a sexual partner who was bigger and more powerful than he was -- wasn't a little bit thrilling.

Bill's thoughts moved on a very different track. Much like John, he'd tried closing his mind to the reality of what was about to happen, telling himself that he could disconnect his brain until it was over and he could get back to the things he was really looking forward to. But now, as he looked down at his son, memories of a lifetime of love and happiness came flooding in.

In all of his fantasies about this day, he never imagined doing anything sexual with his son, but now he wondered if maybe his wife and daughter were right. Maybe it really was foolish to close himself off to a unique and special experience with someone he loved.

Regardless of their reasons, both men found themselves more receptive to the idea of kissing the other than they ever would have guessed. John wordlessly tipped his chin upward and parted his lips. All four members of the family held their breaths as Bill leaned forward and pressed his mouth against his son's. Time seemed to stand still as they stayed that way, frozen like statues, each of them waiting for a reaction from the other.

To his immense surprise, John was the first to respond. He didn't feel that same sort of overwhelming passion that had overtaken him when he was in bed with his sister, but the feeling of another man's lips on his own wasn't nearly as unpleasant as he'd expected. It actually felt quite nice.

A quiet, almost imperceptible moan escaped his lips as he started moving his mouth against his father's. Bill wasn't sure whether he was more surprised at John's reaction or his own jolt of arousal at the thought of his son actively kissing him. He still wasn't sure how he felt about the idea of having sex with other men, but the naughty thrill of doing something so forbidden with his son more than overcame those concerns.

Before either of them were sure what had happened, they were making out like teenagers -- their mouths opening and closing against each other, their lips gliding wetly together in a forbidden dance. Tossing caution to the wind, Bill pushed his tongue into his son's mouth, drawing a much louder groan from deep within John's core. Thinking back on it later, Bill wouldn't be able to put his finger on what, exactly, had come over him in that moment, but the feeling of his son -- the boy he'd raised from an infant -- pressed up against him, ignited something inside of him that he couldn't suppress. He ran his hands over John's body with a frantic desperation, caressing the light musculature of his back and sides before grabbing his ass with both hands and giving it a firm squeeze.

John melted as his father passionately mauled him. His frame sagged under the overwhelming pleasure surging through his body, but Bill's strong arms held him up, keeping their naked bodies in constant contact as they kissed. Gripping his father's muscular shoulders, he held on for dear life, happy to let his father use his body however he pleased.

A jolt of surprise went through them both as their hard cocks rubbed against each other. This was a step beyond what either of them might have felt comfortable with only a moment ago, but the sensation of another man's hard penis pressing up against their own felt so much nicer than they ever would have guessed.

Rather than pull away, they pressed forward, grinding their hips and moaning into each other's mouths as their hard cocks rubbed together, trapped between their bellies. Unable to resist their primal urges for a moment longer, they started thrusting, their hips rolling back and forth and side to side, trying to put maximum pressure on the sensitive undersides of their cocks as they moaned deliriously into each other's mouths.

"Oh, wow..." Emma mumbled. "That's really... Oh yeah -- that's really hot... Oh, Mommy! What are you...?"

The question briefly drew the men's gazes, each of them smiling with wide-eyed excitement as they saw that Susan's free hand had drifted into her daughter's lap where it was diddling away while continuing to masturbate herself with the other. Emma turned to face her mom, gave her a shy smile before leaning in for a chaste kiss.

"That feels really nice, Mom," she said. "Can I touch you, too?"

"Oh god, yes. Please!" Susan said, the sexual mania behind her eyes intensifying with each passing moment.

Soon, Emma was copying her mom's movements, their arms crossed as they toyed with each other's excited cunts. Emma's movements were less practiced than her mother's, but the sheer taboo of having her daughter touching her privates more than made up for Emma's lack of expertise.

As much as both men enjoyed the sight of mother and daughter diddling each other, the visual wasn't enough to distract them from the more immediate pleasure of their hard cocks sliding against each other, and soon they were both back in their passionate embrace, frotting wildly while their tongues competed for dominance in each other's mouths. The pleasure was like nothing either of them had ever experienced, but it wasn't enough.

"Dad, I... I need... I need more," John murmured, his voice thick with unexpected desperation. "Would you... Oh, god... would you fuck me...? Please?"

The rational side of John's brain could hardly believe the words coming out of his mouth, but rationality and logic had nothing to do with it. He'd been looking and touching and exploring all morning, but he was a horny teenage boy, and he needed to fuck. Never in a million years would he have guessed that his dad would trigger that primal desire within him, but each slippery thrust of that long, veiny cock against his own only added to his desperate need to be penetrated -- to feel his father's cock inside of him, fucking and thrusting and cumming inside of his virgin hole.

The motion of Bill's hips slowed as he stared down at him, dumbfounded. He'd been so lost in the physical and emotional whirlwind of making out with his son that he hadn't given any thought to the natural endpoint to their actions. The thought of his handsome son bending over for him, spreading his cheeks wide, practically begging to have his ass stuffed with dick made him surge with arousal, and it took every ounce of willpower he had to restrain himself from pushing John up against the wall and taking him right then and there.

"Are you sure?" he asked, the fire in eyes contrasting sharply with his hesitant tone. "A few minutes ago, you... I mean, we--"

"I don't care. I just don't care! This is so hot, and I don't want it to stop. I want to feel even closer. I want you in me, Dad. Will you? Please?" John begged, practically dropping to his knees in pleading submission.

Hearing that exchange between her husband and son -- more than even seeing the act itself -- was enough to send Susan blasting off into the stratosphere. She gritted her teeth and let out a deep, guttural groan as her ass lifted off of the edge of the bath, and her cunt spasmed and clenched. Both men watched as the pink interior of her pussy revealed itself between her thick dark lips, followed by a gush of fluid that splashed against their legs. Emma, to her credit, kept stroking, gliding her fingers over her mom's pulsing gash, until Susan collapsed against the tile wall like a wet dishrag.

Without her mom's help, Emma returned her own hand back between her legs. Her own explosion followed soon after. Like with everything she did, Emma's orgasm was girlish and cute. A tiny shiver ran from her toes up through her whole body, ending in a quiet mewling whimper.

As Susan's orgasm faded, she slid down into the tub with her husband and son. That her teasing and bullying of them had been successful was surprising enough. Never in a million years did she think things would progress this far this quickly, and she wasn't about to give either of them enough of a pause to reconsider.

"Come here, sweetie," she said as she gently but insistently tugged her son out of Bill's embrace, turning him around and guiding his hands up against the wall. She pressed on his tummy, pushing his ass outward, her own pussy burning with arousal as she helped him assume the position. "Is this how you want it? Is this how you want your Daddy to fuck you, baby?"

"Yes. Please... I just really need it. I'm sorry, but I just really need it," he moaned, growing embarrassed at his pathetic desperation for something that under any other circumstances would have been cause for deep shame and embarrassment.

"Don't be sorry," Susan said, her voice calm and soothing despite the raging inferno building within her. "There's nothing wrong with what you're feeling. It's normal for a boy your age to need sex, and your mommy and daddy are here to help. Isn't that right, honey?" she asked, turning her lust-filled gaze back up to her husband.

Bill hadn't actually agreed to any of this yet, but the look of crazed desire on his face was all the answer his wife needed to know that nothing would stop him from shoving his cock up their son's hot little ass.

"God yes," he murmured, his eyes roaming hungrily over the lithe musculature of his son's back before zeroing in on his ass as it protruded out in his direction, begging for his attention. "Gonna make you feel so good, son. Gonna make you cum so hard on Daddy's dick..."

He jolted in surprise as an unexpected hand wrapped around his steely prick. Looking down, he saw his daughter's wide eyes staring up at him.

"Can I help get you ready?" she asked.

Bill grunted in assent, too lost in his arousal to form a coherent response.

"What a good girl," Susan said by way of encouragement. "John's ass won't lubricate the way our pussies do, so you'll need to get his cock really slick." She cast her eyes quickly around the room before finding what she was looking for. "That lotion over there should do the trick."

John let out another pitiful moan. There was no space in his mind for anything other than his father's cock, and he felt a pang of jealousy as he heard his father moan, knowing his sister's hands were all over that cock -- his cock.

"Oh, my sweet, desperate boy," Susan hummed. "You don't have much longer to wait. Just give me a moment to get you ready, too."

A shiver of anticipation ran down his spine as he waited for his mom to rub lotion onto his ass, much like his sister was doing to their father's cock. He jolted in surprise when, instead, she slid around him and shoved her face deep into his cleft and started lapping hungrily at his butthole.

"Ah--Oh! Ohhhhhyeahhhhh..." he moaned, his legs going all wobbly as he pressed his ass more fully into his mom's face. The feeling of her tongue swirling all around his puckered hole made his stomach flutter as goosebumps rippled across his arms and legs.

In a different version of reality, he might have been happy standing there, rubbing his ass back and forth on his mom's face, but the feeling of something swirling and sliding around back there just made him even more desperate to get fucked -- to feel his dad's thick cock sliding deep up inside of him.

Apparently, Bill felt the same way, because moments later, John heard his mom give a surprised yelp as he pushed her aside. Before he even realized what was happening, his dad was on him. He felt hairy thighs press up against his own and his father's muscular chest cover his back. He let out a moan that his father echoed as a throbbing, lubed-up cock slotted between his legs, sliding parallel beneath his own.

John's heart was pounding so fast. Too fast.

It was really happening. Here. Now.

Driven by a primal urge, John reached down and wrapped a trembling hand around his shaft and his father's, pressing the two together. His dad groaned, hips jerking to thrust against him, his hard, masculine flesh gliding smoothly against both hand and shaft of his son.

"Your daddy wants you bad," Susan moaned, quickly losing herself in her own homoerotic fantasies.

"I... want... him... too..." John grunted between clenched teeth, dizzy with desire.

It was a good thing he did because at that moment, he couldn't stop what was coming. Bill was lost in a sea of confusing and exciting sensations, long past any rational thought besides the ever-growing desperation to fuck his sexy son. He humped against him with senseless abandon, his hips moving on pure animal instinct.

He wanted to claim him, breed him, but also something deeper than that. He wanted to give his son the experience of being taken, of surrendering control the way a woman could when she was fucked. He wanted to show his son what it was like when a man gave in to his primal urges.

And not just any man, but this man -- his father. He yearned to show his son what his daddy could be like when he unleashed the horny beast within.

Above all, he wanted his son to feel utterly conquered. That, at least in this incredible moment, his ass was his daddy's to use and fill whenever he wanted.

"Let me help," Susan said, placing a soft hand on her husband's back, which calmed him -- temporarily surfacing the rational side of his brain. Bill stopped his crazed thrusting as his wife took him by the base of his cock and pressed it firmly against their son's puckered hole.

The sensation of his son's anus against his tip nearly undid him. He released a ragged gasp as he clung to the tattered threads of his self-control.

"Be careful with him," she said, feeling a pang of maternal concern surface through her own sexual fog.

Bill nodded and gently pressed forward.

John might have been worried by the feeling of his dad's dick pushing up against his ass if he wasn't already so desperate for it. His own erection strained forward, fully engaged at the thought of getting his ass reamed out by his dad's cock -- of feeling another body on him and in him -- of finally having real sex with someone he loved and desired.

Later, he would wonder how he managed it so easily, but in that moment, his desperate desire to be penetrated was all it took for him to open himself to the insistent pressure of his dad's cock. Bearing down on him, he felt something stretch and give way. There was a moment of discomfort, but it was nothing next to the strange sensation of hard, throbbing flesh sliding deep into his body.

"Unnnnghhhhhh... Oh D-Daddy..." he groaned, his mouth hanging open in a stupor as a line of drool slid from his lips and down the drain.

"Yeah... Oh yeah... Oh, Fuck Yeah..." Bill replied as he steadily fed himself deeper and deeper into his son's willing ass. He gripped his son's hips tightly, eyes locked on the sight of his hardness sinking past that stretched ring. "Your ass feels so fucking good, John. Sooo fucking good..."

Susan stared wordlessly up at them, still not quite believing that any of this was really happening -- that her husband and son were fucking. She couldn't even say that they were doing it for her amusement anymore. It had gone so far past that -- a fact that made the whole thing even more mind-meltingly hot. Catching Emma in the corner of her eyes, the mother-daughter pair locked gazes for a moment, enjoying a shared moment of utter disbelief before Emma wordlessly came and sat in her lap. Susan sighed as she wrapped her daughter's small body up into her own, touching her breasts and belly as Emma rested her head in the crook of her neck while watching the two men fuck.

John was completely unaware of any of this. The almost unbearable pressure on his insides was the only sensation his brain could process. That, and pure disbelief that something so filthy and exciting could really be happening. He'd never felt so completely full before, and if he didn't know any better, he would swear his dad's dick was all the way up in his stomach.

Of course, it wasn't until Bill pulled out and gave a steady thrust forward that the real pleasure began. John didn't understand what was happening, but there was something inside of his ass that felt unbelievably good when his dad rubbed against it. It was like there was a direct connection between the inside of his ass and his cock that felt so much better than anything he'd accomplished with his hands. If he was being honest, it even felt better than the blowjob he'd received from his mom downstairs.

"Why does it--OH! Why does it feel so good?" he asked no one in particular as his dad picked up the pace, fucking into him with deeper and faster strokes.

"Feels good for me, too," Bill grunted as he bottomed out yet again in his son's ass. "Feels really fucking good..."

Fireworks went off behind John's eyes every time the weighty presence of his father's cock slid against that special spot inside of him. Without even realizing what he was doing, he started jerking off, his motions unconsciously matching each thrust of his father's hips.

"I want to help him, Mom," Emma said, looking up at Susan with big doe-eyes. "I want to help Johnny feel good."

"God, yes. Go. Do it," Susan urged, practically shoving her daughter out of her lap and watching with bated breath as Emma knelt between John's legs and started swirling her tongue over the head of John's cock as it poked in and out of his tightly clenched fist.

John felt a moment of confusion as his sister's mouth added another layer to his sensory overload. A lazy smile spread across his face when his eyes finally came back into focus, giving him a wildly erotic view of his adorable little sister, her lips pursed as her small pink tongue snaked out over the tip of his penis. Sensing his gaze, she looked up at him. "Can I, John? Can I suck it? I really want to."

John gave a desperate nod. "Y-yes. Puh-puh-please!"

He moved his hand out of the way and groaned as the warm suction of his sister's mouth replaced the familiar sensation of his tight fist. Emma made a happy noise deep in her throat that reverberated through his cock and made him groan.

Wanting to get a better look, Bill lifted up on his tip-toes, digging his cock deeper into John's ass as he peered over his shoulder..

Seeing her father's face smiling down at her, Emma pulled away and flashed him a slutty smile, keeping her eyes locked with his as she opened wide yet again to engulf her brother's cock.

"Take it all in, babe," Susan said in a tone of voice that could only be meant for her husband. "Do you realize what's happening? You're fucking our son. Your dick is inside of our son. Fucking him. You're fucking the boy we made together. The boy we raised. And he's so happy. Aren't you, John?"

"Mmm... so happy..." John mumbled, too overwhelmed with pleasure to do more than dumbly parrot his mother.

Her words were having their intended effect on Bill, who let out another passionate growl as he started slamming himself in and out of John's ass, drawing plaintive yips of joy from the teenage boy's lips.

"And that's your daughter down there," Susan continued. "On her knees... sucking our son's cock. Isn't she beautiful? Doesn't she look so fucking beautiful down there sucking cock -- like she was made for it -- made to suck her brother's dick and eat his cum. Isn't that right, Emma? Aren't you excited to eat your brother's cum? To feel it filling up your mouth? To have that sperm swimming around in your belly?"

"Ungh...MmmmHmmm..." Emma gurgled, unwilling to take her brother's hard cock out of her mouth for long enough to give a proper reply.

It was all too much. Every filthy word spewing from his wife's mouth pulled Bill closer and closer to the abyss until his balls finally contracted and he gave one final shove as deep into his son's bowels as he could.

"OHHHHFUUUUUUUUUCK!" he bellowed as his dick started pulsing and twitching, flooding John's rectum with thick streamers of cum. His hips thrust involuntarily into him in short jerks as he held his son tight to his body, trying to implant his potent seed so far up into him that it would never come back out again.

The noise that came out of John's mouth was different. Instead of a passionate roar, he let out a quiet, breathy moan that sounded a bit like a balloon deflating. That sensation of incredible fullness was soon accompanied by a warm and wet feeling that seemed to fill up every empty space within him. It was everything he'd wanted and more -- a sense of complete love, fulfillment, and eventually, release.

Emma let out another happy moan as she felt her brother's cock swell in her mouth, followed by a thick rope of semen. She did her best to hold it all in, loving the feeling of his gooey spend sloshing around in her mouth even as his hard prick kept firehosing more and more of the stuff between her lips.

Eventually, she sputtered and pulled away, moaning with disappointment as a flood of sperm poured out of her mouth and down over her chin even as another blast of John's cum sprayed against her face. A big rope of the stuff drew a diagonal line from her forehead down to her cheek, followed by a few more spurts that painted flecks of the stuff over the rest of her smiling face.

No longer able to support his own weight, John fell forward, shuddering at the strange feeling of his dad's cock sliding out of his ass. He gave his sister an exhausted smile which she returned before leaning in to kiss him. They made out that way for a moment or two, trading his cum back and forth in their mouths before John felt the familiar sensation of someone's mouth on his ass.

Glancing back behind him, he smiled as he saw his mom's green eyes peering up at him from above his ass. Unlike before, this time he could feel her tongue inside of him, swirling this way and that, searching desperately for her husband's spend. Feeling incredibly wicked, John intentionally bore down, pushing a thick wad of cum directly into her waiting mouth and receiving an appreciative moan in return.

Bill sat sprawled out at the other end of the tub, his soft cock hanging between his legs as he watched the rest of his family casually lick and suck cum from each other's orifices. In the afterglow of his intense fuck, it was hard for him to believe that he'd actually fucked his son. It had never been part of the plan, but now that the seal was broken, he knew it would be something they'd do over and over again.

Almost on cue, the shower water started turning cold, snapping all four of them back into reality. With various groans and stretches, the family rose to their feet and with what little warmth was left from the shower, quickly soaped and rinsed off their bodies.

They regathered in the parents' bedroom, where Bill made a point of snuggling up close to his son. "Are you okay?" he asked, the parental concern in his voice contrasting sharply with the animalistic desire that had coursed through him a few minutes prior.

"Yeah, Dad. I'm good," John replied, smiling as he nuzzled against his dad's shoulder. "A little sore, and a lot confused, but really really good."

As if it was the most natural thing in the world, Bill leaned down and kissed him full on the lips. There was no furious passion this time, just happy affection between two men who loved each other deeply.

"See? I knew you'd like it," Susan said with a condescending smirk, drawing their attention.

"I didn't think you'd like it that much, though," Emma added.

"I guess we forgot to follow the cardinal rule of this household," Bill said. "Mom's always right."

"Damn right I am," Susan replied, snuggling close to her husband on the other side. "And since we're all in agreement that I'm the divinely chosen ruler of this family, I hereby decree that it's time for lunch and Christmas presents. What say you?"

The rest of the family eagerly agreed, suddenly realizing how empty their stomachs were, now that their immediate sexual needs had subsided.

Downstairs, Susan went to work making sandwiches while her family stood around the kitchen, chatting as if it was a normal Christmas morning. Any residual awkwardness from their sexual encounter faded away as they sat around the dinner table and simply enjoyed each other's company. With their bellies full, and the dishes put away, they returned to the living room and the pile of presents under the tree.

For John, the idea of opening his Christmas gifts wasn't nearly as exciting as it had when he'd woken up, but there was something comforting about engaging in a normal family activity after all the unusual events of the past few hours.

As the family took their places around the tree, Bill took on his traditional Santa Claus role, handing out gifts to everyone in turn. John got a new gaming console and some games, which he'd been asking for. He found it funny that something he'd wanted so badly now seemed like a nice afterthought.

Emma was thrilled to receive package after package of books, movies, and music. She jumped up and gave her dad a big hug, then surprised him by pulling him into a passionate kiss. John and Susan could see her small pink tongue thrusting in and out of his mouth. "Oh Daddy, thank you!" she exclaimed.

Susan stood next to them and put her hands on her hips. "What? You don't think he picked all of that out by himself, do you?" she said in mock annoyance.

"Oh, Mommy, I love you so much, too!" Pulling away from Bill, she met her mom in an equally passionate embrace. Susan smiled inwardly, reveling in the unique pleasure of making out with her hot daughter. As they kissed, she reached down to grope Emma's ass, pulling her tighter into him. John was certain that this was a sight he'd never get sick of seeing.

Susan gently pushed Emma away, cutting their kiss short. "There's more, dear," she said with a sly smile on her face. John's intense focus on Susan and Emma's kissing had distracted him from his father's sudden disappearance. He was surprised to see him re-enter the room carrying two more packages.

"Your Dad and I weren't sure how you two would react to our new lifestyle, so we kept these presents away from the tree. I think it's safe to open them now, though," Susan said.

Both packages were small, and Bill handed one to each of his children. Emma started with hers first, revealing a sheer pink teddy with a matching pair of frilly pink panties. She gasped in surprise at the gift. She'd never considered wearing sexy underwear before, but delighted in the idea of dressing up and showing off for her family's enjoyment.

She ran to the bathroom to change, taking a moment to admire the sight of herself in the mirror. She loved the way the soft fabric accented her nipples and hugged her slender hips. Deciding that she wanted to put on a show, Emma put her robe back on before returning to the living room.

The rest of the family waited in anticipation as she re-entered the room and stood before them. With a demure smile, Emma opened her robe and let it drop to the floor. John, Susan, and Bill were taken aback by her beauty. The outfit made her look innocent, but intensely sexual at the same time, just as her parents had hoped it would. They stared at her in awe, each of them wanting nothing more than to ravish the beautiful girl standing before them.

"Your turn, John," Susan said as she handed the other box to her son.

Not even the sight of his sexy sister could overpower his curiosity about its contents. He quickly unwrapped it and was a bit disappointed when he revealed what appeared to be a perfectly normal photo album. Confused, he flipped through a few pages, a big smile forming on his face as he realized that there was nothing normal about this collection of photographs.

The binder contained page after page of pictures of his mom in various poses, doing all sorts of sexy things. His eyes were immediately drawn to a shot of her from behind. Her asshole and pussy were fully exposed, and a big glob of cum was dripping out of her split.

"Jesus, this is the hottest thing I've ever seen... next to the real thing, of course," he said, looking up at his mom.

Susan blushed. Despite all they'd done, she was still wrapping her head around her family's new lifestyle. Logically, she knew that there was something shameful about showing her son pictures of her freshly fucked pussy, but seeing the boyish glee on his face was so unbelievably flattering and exciting. She couldn't wait for him to see the rest of the pictures.

"Keep reading. There's more."

He continued to flip through the book, eventually reaching a set of pictures showing his mom and dad having sex in different positions. Their family had already transgressed so many laws of society and morality together, but he still hadn't actually seen his mom getting fucked, and seeing the look of delirious pleasure on her face while impaling herself on his dad's cock brought John's own erection back to full mast.

Flipping a few pages further, he saw that the album also included pictures of his Aunt Sally, Uncle Craig, and his cousins. One picture that caught John's eye was a side-shot of his uncle fucking his cousin, Jenny, doggy-style. His aunt lay beneath them, pressing her tongue fully against the joining of his cock and her pussy. Everyone looked like they were having the time of their life.

The next page showed John's other cousin, Steve, burying his cock to the root in Aunt Sally's throat. Later pictures showed Steve on top of her, his dick shoved deep inside of her pussy. Other shots showed Jenny sitting in her father's lap. In one close-up, John could see his cousin's pussy lips dragging along her father's shaft, leaving a wet trail along the exposed part of his cock. The next picture was taken from farther back and showed Craig playing with his daughter's sizeable breasts while he fucked her.

John looked up at his mom in surprise. "Wow! I can't believe this. Do they know you're showing me these?" he asked.

"Of course they do!" Susan replied. "In fact, they took these just for you. It was your aunt's idea. She said to consider it a preview of what it will be like when we all get together as one big family." Suddenly, John's mind filled with images of both families engaging in a big, sweaty fuck-pile and hoped that visit would happen sooner rather than later.

Later pages focused on his Aunt Sally. Her body was so different from his mom's statuesque figure and his sister's nymph-like youth and vitality. Sally was thick and curvy, with fleshy thighs, a plump ass, and big, pendulous tits that sloped down either side of her round belly. It wasn't the type of body he was used to seeing in an erotic context, but that didn't make her any less sexy. He could only imagine how nice it would feel to be on top of her, feeling her soft, pillowy flesh beneath him as he fucked away in her hairy cunt.

A picture that became an instant favorite showed Sally in profile, laying on her bed. Using both hands, she held up her sizeable breasts while her son fucked his cock into her cleavage. From the smiles on their faces, it was clear they were having a great time. John hoped that one day he'd get to feel those soft tits wrapped around his own cock.

The last picture in the album showed Sally and Jenny sitting side-by-side, smiling at the camera. Their legs were spread wide, exposing their well-fucked pussies. The words "Merry Christmas, John!" were superimposed on the image above their smiling faces.

"I think he likes his gift, honey," Bill said, chuckling at the mesmerized look on his son's face.

"I think you might be right, dear," Susan replied. Turning to her son, she said, "Your aunt and I thought it would be nice to give you something to keep you entertained when your sister and I aren't available."

John gave her an appreciative smile. "Thank you both for all of this. This has been the best Christmas ever." Getting up out of his chair, he gave his dad a big hug, his hard cock once again rubbing up against his dad's penis. The two men shared a brief kiss before John pulled away and went to his mom.

Their embrace was more overtly sexual. Pulling him in close, Susan shoved her tongue deep into her son's mouth and grabbed his ass, pulling him into her. Moving on pure animal instinct, he thrust himself against her, loving the feeling of the underside of his cock rubbing against the soft skin of her belly.

Bill coughed lightly to get their attention, and the mother-son pair reluctantly parted. "Since it looks like you two are ready to go another round, how about we go ahead and take the family portrait!"

At that moment, taking the portrait was the last thing on John's mind, and it annoyed him that his dad had interrupted the moment he was having with his mom.

Emma was a bit quicker on the uptake. "So does that mean we're going to... do it? Have sex, I mean? Like in the pictures they took for John?" she asked, sounding more nervous than excited.

"If you're ready for that," Susan replied, stepping away from John and taking a seat next to her daughter.

There was a long pause as Emma fidgeted in her seat, nervously crossing and uncrossing her legs. "I want to. I really do," she said. "But I'm scared. I know you said it stretches down there... but how? John's dick is so thick -- so much thicker than my finger."

Susan smiled and wrapped an arm around her daughter's shoulder, drawing her close. "I won't lie, honey. It does hurt a little the first time, and I know how scary that can be with a part of your body that is so sensitive. But once that passes..." she closed her eyes, replaying thoughts of Bill's cock sliding up inside of her body. "Mmm... There's just nothing like it. It's impossible to describe until you've felt it for yourself."

Hearing the obvious lust and excitement in her mom's voice eased Emma's concerns, if only a little. "Could I see? I mean... could you show me what it's like?"

"What an excellent idea," Susan replied, her eyes shining with arousal. "What do you say, John? Want to show your little sister what a woman's body is capable of?"

John was taken aback by the question, but only for a moment. "Oh god, yes. Can we? Really?" he asked, unable to hide his excitement at the prospect of finally having real sex with his beautiful mother. Almost as soon as the words left his mouth, he realized how he must sound to his sister.

"I mean... if that's okay with you, Emma," he added. "I'm really excited to do it with you, too, and I can wait until you're ready if you want me to."

Emma's heart swelled with adoration for her big brother. She could see how excited he was to lose his virginity and could only imagine how hard it would be to hold himself back. But he was willing to do so for her. She'd never felt so loved, and in that moment, she would have done anything to make him feel the same way.

"Go for it, bro," she said with a big, excited grin on her face. "Make Mom cum like crazy on your cock, then you can come show me what you've learned."

The beaming smile on John's face filled her with unspeakable joy, but that happiness grew by multitudes when he knelt next to her on the couch, placed a loving hand on her cheek and pressed his lips to hers. His kiss was soft and loving and conveyed the unspoken truth that, while he was beyond excited to fuck his mother, Emma was the one he held closest in his heart.

"Have fun," she said, pushing him away with one hand while she wrapped her small fist around his cock with the other. "I can't wait to see this thing buried up in Mom's pussy."

John just grinned and nodded. Rising to his feet, he took his mom's hand and pulled her upward. With her face even with his, he palmed her ass, desperately pulling her naked body up against his as he kissed her with passionate intensity.

Susan let out a happy yelp of surprise at her son's sudden aggression and eagerly kissed him back. "Get the camera, Bill," she said, her voice coming out in a breathless moan.

The reminder of his father's presence momentarily blunted John's excitement. He was, after all, about to fuck the wife of a married man. But a quick glance at Bill's smiling face and hard cock confirmed he had nothing to fear.

"Be right back," Bill said, before dashing out of the room.

Without a word, John and Susan were back at it, forcefully mashing their lips and tongues together as they devoured each other's mouths. John couldn't get enough of his mom's taste Their hands roamed freely over each other's bodies, groping and squeezing with mindless abandon.

Susan was more than ready for him. Her nipples ached as they dragged across his chest, and her pussy felt impossibly squishy and moist, her juices sliding out of her and wetting her thighs. This was what she'd anticipated for months -- the moment when she'd usher her only son into manhood. She would have happily let him ravish her right there, and her heart raced at the thought of him bending her over the couch cushion and taking her -- fucking his thick cock up into her wet mommy-hole until he painted her insides with cum.

But there would be time for that later. This was about more than just what she wanted. She was still his mother, and she still had a responsibility to teach him -- to show him how to care for his partner and make sure she always came back for more.

"You turn me on so much, son. I can't wait to feel you on top of me, fucking me with that big, hard cock. Your mommy's going to make your cock feel so good, baby." She grabbed one of his arms and shoved it between her legs, encouraging him to explore the wet and hairy entrance to her sex.

"Tell me what to do, Mom," he said as his fingers swirled around in her swampy wetness.

"You're doing great, baby," she hummed. "But remember what I taught you this morning. Women love to be complimented. Feeling your body is nice, but knowing what's going on in your brain is even nicer."

"God, Mom. You're so beautiful... so fucking gorgeous. I love your tits. Your nipples look so sexy. And your pussy..." he let out another hungry groan as his palm closed over her sex, squeezing her feminine folds and making her knees buckle. "I just love you!"

Mind-numbing jolts of pleasure shot from Susan's drooling cunt out through the rest of her body, and for a second, she thought she might faint. With a reluctant moan, she stepped back and sat down on the couch next to her daughter, who was watching the whole scene with wide-eyed fascination. Her gaze caught momentarily on her husband, who stood behind the tripod, snapping photographs before turning her attention back to her son.

"Come here," she said, making a come-hither motion with her index finger as she spread her legs wide.

John eagerly complied, stepping up between her legs, his steely cock pointing right at her face.

"I want you to get down on your knees and tell me what you see."

John did as she asked. The sight that greeted him took his breath away. His mom's pussy was red and swollen, framed on either side by damp, matted curls that clung to her flesh. Her dark inner lips hung open, giving a tantalizing glimpse of the pink delights within. Her odor -- a mixture of sweat and arousal -- triggered something primal within him, a need for fulfillment and release that was quickly growing beyond his control.

"You're so wet, Mom. So wet and so beautiful."

"I'm that way because of you, baby. I'm in heat, and I won't be satisfied until my son's cock is in me -- fucking me, and filling me up with cum."

Turning to Emma, who was leaning forward, staring down at her mother's sodden crotch, she said, "You feel it, too, right? That emptiness? That need to be filled? To be fucked?"

Emma nodded, already rubbing at the wet spot in her pink panties.

"There's only one way to make it go away..."

Turning back to her son, she said, "I'm ready for you, baby." Before John could respond, she shifted her body lengthwise on the couch, reclining against the arm-rest, so her daughter (and her husband's camera) could get a good view of what was about to happen. "Now get up on top of me. Don't worry, I won't break."

Moving awkwardly at first, John clambered up on the couch, struggling to find a place for his hands and feet before finally giving up and laying down on top of her, trapping his hard cock against her warm slit. Susan let out a contented sigh as she felt the full weight of her son's body on top of her.

"Yes, that's it," she hissed. "Let Mommy take care of that hard cock."

Reaching between them, she grasped his shaft and dragged it back and forth through her wetness, bathing him in her arousal before positioning him right at the precipice of her opening.

Susan smiled lovingly up at him, caught between motherly affection and wanton arousal at the thought of her boy's cock worming up into the same hole from which he'd emerged nineteen years ago. Holding himself at her entrance with one hand, she used the other to pull him inside.

"Mmmm FUCK!" Susan screamed. He wasn't as long as his father, but he was thicker, and that extra girth stretched her in ways she'd never felt before. She was already delirious with arousal, and the feeling of her son's cock penetrating her was all it took to trigger a small orgasm.

John had never felt anything quite so wonderful as the slick walls of his mother's cunt as they hugged his invading cock. He held himself deep inside of her, enjoying the way her pussy rhythmically pulsed and twitched through her shuddering orgasm, watching in awe as her eyelids fluttered and her head shook back and forth, her disheveled red hair covering her face. The feeling of her lubrication flooding his cock as she came amazed him.

"Goddamnit! Your cock feels so good, baby," she sighed as she caught her breath. Slight tremors still shaking through her as her orgasm subsided. "Okay, it's time for you to fuck me. Normally, I'd tell you to take it slow and build toward the big finale, but I just can't wait any longer. I can teach you some technique later, but right now, I just want you to have your way with me. Use me. Do whatever feels good, and when you're ready, I want to pump me full of cum."

John didn't need to be told twice. He started thrusting in and out of her with gusto, reveling in the feeling of her wet hole stretching to accommodate him. He was thankful for all the play that led up to this moment. The many orgasms he'd already experienced gave him some staying power and let him enjoy the wonderful sensations without feeling overwhelmed. "God, Mom, this feels so much better than I ever could have imagined. I never want to stop fucking you!" he said, grunting with each frantic thrust.

The sounds and smells of sex filled the room as Susan's guttural moans nearly drowned out the wet squelching sound of his cock pounding in and out of her. "Oh baby, your cock feels so fucking good. I can't believe my baby boy is fucking me. I can't believe I'm taking my son's cock in my hot, nasty cunt!" With each thrust, she felt his pubic bone grind against her clit, driving her closer and closer to a second, more powerful release.

While they fucked, father and daughter watched in awed silence. Emma's panties were down around her knees as she furiously masturbated, never having seen anything as naughty or exciting as her beautiful mother's pussy stretching tight around her brother's cock. Any doubts she had about wanting the same treatment were quickly forgotten as she fantasized about switching places with Susan.

Bill was turned on too, but he avoided touching himself, wanting to save his energy for his daughter. He distracted himself by taking pictures, trying to catch every moment of ecstasy on camera. "Fuck her, John," he said, egging his son on. The sight of his wife getting railed as she gave herself over to degenerate lust, excited him in ways he couldn't explain. In a way, he felt like he was seeing her true self for the first time, and she'd never looked so beautiful.

John was totally focused on fucking his mother. He supported himself on his elbows as he hammered into her and reveled in the look of passion on her beautiful, freckled face. "I... Ungh... Love... You... Ooh... Mom!" he gasped. The sight of her breasts swaying on her chest with each down-thrust of his cock beguiled him, and he bent his neck to take one of her erect nipples between his lips.

"Mmmm, I love you too, son," she moaned. "Yessss... that's it... I missed having your mouth on my breasts..." After several minutes of this, she planted her feet on the cushions and started humping back against him. She wanted to feel every inch of him filling her up. John took a firm grip on her hips and increased the pace and intensity of his fucking.

"OH GOD! KEEP FUCKING ME, SON! RIGHT THERE! JUST LIKE THAT!" she screamed. The sounds and smells of their coupling, combined with the feeling of his cock surging in and out of her, ushered Susan into another powerful orgasm. She wailed deliriously as her eyes rolled back in her head as her legs and stomach spasmed uncontrollably. Her pussy clamped down around her son's cock as a hot spray of her cum shot up between them, soaking their bellies as they wriggled and writhed together. This orgasm was much more powerful than the one that preceded it, and her son's insistent fucking drove up the intensity until every nerve in her body felt raw and painfully exposed.

John pounded her for all he was worth, enjoying the velvety warmth of her insides as they pulsed around him. As he sloshed in and out of her, he couldn't help but be amazed that she was so turned on. Before he knew it, he was right there with her, coming inside of her clutching hole.

"Oh shit, Mom. I'M COMING!" He yelled, grunting hard as he emptied the contents of his balls into his mother's womb. The feeling of his cock swelling inside of her was more intense than any orgasm he'd ever experienced. His cock jerked and pulsed over and over, filling her belly with his liquid warmth. When their orgasmic high started to fade, he collapsed on top of her, laying his head against her heaving breast. He breathed deeply while listening to her heart pounding in her chest and feeling their combined juices dripping out around his softening prick.

Emma kept rubbing her soaked pussy while they fucked. The sight of her brother's hips jerking and his balls contracting as he came inside their mom's pussy had made her cum as well. Hearing his daughter's yelps of pleasure, Bill directed his camera at her, snapping a few shots of her hunched over frame as she rubbed desperately between her legs. He couldn't wait for the opportunity to fuck her.

For several long minutes, John and Susan snuggled with each other, reveling in the afterglow of their first mating. They kissed each other tenderly, and Susan nuzzled herself into her son's chest, enjoying his scent. "I love you, Mom," he whispered as he ran his hands through her tousled hair. "That was the best ever."

"Ever?" Bill asked with a sly smile, gripping the base of his dick and pointing it in his son's direction.

John blushed. "Okay, maybe it was a tie," he said, his asshole flexing as he remembered the mind-numbing pleasure he'd received at the end of his father's cock.

Susan giggled, making her pussy squeeze down on her son's cock, ejecting a load of ejaculate and her own creamy lubrication from their joining. She felt like a completely wanton slut having let her own son fuck her in front of the rest of their family, but she also felt appreciated and cared for in a way that she hadn't since her children were young. She couldn't remember the last time she'd felt so completely fulfilled.

"You were so good, baby," she said. "This was everything I hoped it would be. You made me come so hard!" She hesitated a moment. "You don't regret anything, do you?" she asked.

"Mmm, not one bit," he said, sighing contentedly and nuzzling closer to her. "I can't wait to do it again." As they snuggled, his soft cock plopped out of her pussy. With a reluctant sigh, he rolled off to her side and knelt next to her on the floor below.

Bill got right up between his wife's legs and started snapping pictures as a river of cum and pussy juice flowed out of her. The meaty lips of her cunt hung open slightly, and the knowledge that it was his son's cock that had made such a sloppy mess down there sent a dark shiver of excitement down his spine.

He stepped back a bit and took a few shots of Susan smiling up at the camera. In a picture that would become one of John's favorites, she held her pussy open, proudly displaying her creampie to the camera. It reminded him of the last shot in the photo album, but knowing that it was his cum leaking out of her made it seem so much more filthy.

Seeing her brother's cum leaking out of her mother's split triggered something in Emma's brain. Almost without thinking, she dived head first between Susan's splayed legs and started lapping away, reveling in the taste of her brother's spunk as it mingled with something new and equally delectable. She licked and sucked selfishly at her mom's gash, only caring about filling her mouth with as much of that thick, briny fluid as she could get.

Her mom yelped in surprise before chuckling at her daughter's eagerness. From his position, John had a closeup view as Emma used her tongue to make broad swipes from her mom's puckered asshole to the top of her clit. "Mmmm, your cum tastes so good, bro," she said, temporarily lifting her head out of her mom's sodden crotch. He felt a shiver of excitement at the sight of his cum glistening around his sister's lips as she flashed a wicked smile at him before getting back to work.

Susan smiled lazily down at her daughter as she lapped at the cleft between her legs. She wasn't close to cuming again, but she was content to lazily enjoy the feeling of her daughter's active tongue. Pulling her gaze away from Emma, she turned back to her husband. They smiled at each other, silently acknowledging that they were more than happy with how things had turned out.

After taking a few more pictures, Bill stepped forward and gently displaced his son. Dropping to his knees, he lightly traced his hand up and down his wife's body, making her shiver. "Was it everything you hoped?" he asked, smiling.

"Everything and more," she replied. "Are you okay? It didn't bother you...? Seeing me like that?"

"You tell me," he said as he guided one of her hands down to his turgid cock. They kissed deeply, and her hand grasped his hard-on, delicately stroking his excited manhood. On the upstroke, she encircled the head of his cock with her fingers, giving it a light squeeze, which made him tremble and moan.

Before too much of this had transpired, Emma rose from her mom's pussy, wiped away the bits of shiny fluid sticking to her lips and cheeks, and meticulously licked them off of her fingers. She smiled shyly at John, then leaned over and took his soft cock into her mouth and started cleaning him off as well. Like his mother, he was too spent to reach full arousal, but her tongue bathing his cock still felt warm and nice. Emma was quickly learning that she loved to suck cock. Even though he wasn't hard, she just loved the taste and feel of his flesh in her mouth.

Bill and Susan were entranced by the sight of their daughter going down on their son. As Susan stroked him, he gently cupped and fondled her breasts, drawing contented sighs from her lips as she savored the familiarity of her husband's touch, feeling unbelievably lucky that he was as aroused by the idea of incest as she was.

"God Susan, I still can't believe what a turn-on this all is," Bill said, breaking the silence.

"I know. I can't wait to see Emma's face when she realizes how amazing it feels to be full of this lovely cock of yours," she said, giving his erection an extra little squeeze for emphasis. That comment got their daughter's attention, and she reluctantly extracted herself from her brother's cock.

"Would you like that?" Susan asked, locking eyes with her daughter.

Emma looked like a deer in the headlights. "I would... I mean, I do. But I really want John to be my first. Is that okay?" she asked, her eyes downcast, worried about disappointing her father.

"Oh, my sweet girl," Bill replied, giving her a comforting smile. "Of course that's okay."

"Thanks, Dad," Emma replied, her expression brightening at the sincerity in his voice. "I really want to do it with you, too. Like, really," she added for emphasis.

"I know, honey. I do, too, but we have all day plus the rest of our lives."

Emma and John both paused at that. It had been an incredible day for both of them, so much so that they hadn't given much thought at all to the fact that their lives had changed in a way that couldn't be undone -- not that any of them wanted to, of course.

"You do have a problem, though," Susan said, making eyes at John's soft cock. "If you want your brother to be your first, you'll have to get him ready. Even youth has its limits."

"I can do it!" John said with determination. His sister needed him, and there was no way he would let her down. Not today. Not ever. "But if you want to help, I wouldn't say no," he added, making eyes at Emma's lithe body, clearly visible through the transparent material of her top.

"Mmm, give me that cock!" she demanded, practically pouncing on her older brother. They wriggled and squirmed together, giggling playfully as they tried to situate themselves comfortably on the crowded couch.

Eventually, John found himself reclining in his mom's lap, her legs spread out on either side of him as his head rested right between her breasts. Emma knelt at the other end of the couch between her brother's legs, smiling wickedly up at him as she sucked his cock and played with his balls. Bill stood above them, snapping photographs with one hand and stroking his cock with the other. Emma's panties still hung around one of her ankles, and he couldn't resist pulling them off of her and taking a deep whiff, inhaling the refreshing scent of his daughter's arousal before tossing them to the floor and snapping a few close-up shots of her bare cunt.

"Come here, honey," Susan said, drawing her husband closer.

Tilting his head upward, John watched as his mom opened her mouth wide and started sucking on his dad's cock. It wasn't the same sloppy face-fuck she'd given her son earlier that morning. This was much more intimate and loving. She stroked the base of his shaft and planted wet, tongue-filled kisses all around the sensitive ridge underneath his cock-head. She stared up at him, her eyes wide with adoration as she sucked. John could sense the bond between them -- different, but no less intense than the one he shared with his mother.

Turning his attention between his own legs, he saw his sister staring up at him with that same devotion and intensity of feeling. His heart practically melted. He'd had crushes on girls in the past, but what he had with his sister felt so much more real. He adored her in every way and knew she felt the same for him.

Reaching down, he palmed her cheek, gently stroking her as she made love to his rapidly hardening prick. "You're doing such a good job, Emma," he said. "I love the way you suck me."

She just moaned and wiggled her hips. It was only then that John realized that one of her hands was still shoved between her legs. The mere thought of his sister's plump pussy, dripping wet and ready to fuck, excited him enough to reach full hardness yet again.

"I'm ready if you are, sis," he murmured.

"I noticed," she replied, grinning up at him, her lips and chin wet with saliva and the remnants of the load he'd deposited in his mother's cunt just a few minutes prior. "I'm ready, too. Or at least I think I am. How do you want me?"

"Why don't you switch places," Susan suggested.

"Okay," Emma replied, a hint of nervousness in her voice as she carefully extricated herself from between her brother's legs and stood by the couch while he did the same.

Settling back down between her mom's legs, she glanced upward, much as John had done. She smiled at her mother and father as they stared down at her. Being the object of so much attention made her feel shy and squirmy, but having them there with her for this moment just felt right.

"You're so beautiful, Em," John said, standing on his knees between her spread legs.

"You're beautiful too, John," she murmured. "I mean -- well... you know."

He just smiled and nodded before falling forward and planting a passionate kiss on her lips. Emma groaned and squirmed beneath him, trying to press as much of her naked flesh up against his hard, masculine body as she could.

Breaking their kiss, John moved lower, licking and kissing her chin and neck, and eventually reaching her breasts, which in her reclining position, had disappeared entirely save for the pair of stubby pink nipples that rose from her chest. Remembering what his mom had done earlier, he moved back and forth between them, gently nipping one with his teeth and tweaking the other with his thumb and forefinger.

"Oh, Mommy!" Emma groaned, staring up at her mom. "Johnny's making my titties feel sooooo good."

"He must love you very much," Susan replied, the words catching in her throat as her emotions threatened to overwhelm her.

"I do," John replied, coming up briefly for air before going back for more.

Just when Emma was starting to think she couldn't take it anymore, John moved lower yet again. His tongue traced a line down her sternum, making her giggle when it swirled over her flat tummy and into her belly-button. Moments later, he reached the true source of his exploration -- the apex of his desire. The outer lips of her pussy parted slightly, giving the barest hint of what lay within as a thin trickle of her feminine juices leaked out of her and down to the pink star of her anus. Even with his limited experience, he knew that his sister was as ready to get fucked as she would ever be.

He gently cupped her mound, testing its firmness and pliability before tracing a finger through her moist slit. His eyes went wide as she seemed to open up just for him. The small pink petals of her inner lips were so different from the thick folds of his mom's pussy, and John thought they were even more beautiful because they belonged to his little sister, who he loved so very much.

With one last smile, he leaned forward and tasted her. He moaned as his tongue swirled around in her wetness. Her flavor was so strangely familiar -- immediately recognizable as belonging to his sister, despite being so different from anything he'd tasted before.

"Ohhhh, Johnnnny!" Emma moaned, bucking her hips up into her brother's face.

"Lick higher," Susan said, directing him as she ran her palms up and down her daughter's torso, helping Emma relax while also getting a dirty thrill of her own.

John did as she asked, finding the hard little knot of flesh at the top of her split. What surprised him even more was the way his sister shrieked and jerked in surprise when he pressed the flat of his tongue against her.

"You just found your sister's clit," Susan explained. "Focus on that if you want to make her feel really good."

He did as she instructed, swirling his tongue in steady circles around that sensitive bundle of nerves. All the while, he kept his eyes locked on his sister's pretty face, reveling in the way her features twisted in delicious agony with every flick of her tongue. He hoped she could feel the same sense of loving devotion he'd received from her when their positions had been reversed.

"Nnnnghhh! Mmmgonna... gonna... I'm gonna cum!" she shrieked as her consciousness started to unravel.

John pulled back, watching with excited fascination as his sister lost control. Her pussy flexed open and shut, spurting out little dribbles of fluid as her legs kicked wildly in every direction. Susan took her hands, interlocking her daughter's fingers with her own. She held her daughter close, whispering words of encouragement to her as suffocating waves of pleasure washed through her body.

It wasn't until it was all over that Emma realized she'd stopped breathing. Her lungs burned as she sucked in as much air as she could, panting as her normal bodily functions started reasserting themselves. The first thing she saw was her brother's smiling face looking down at her, his adoration making her feel unbelievably loved.

She'd fantasized about this moment so many times, though never in such vivid detail. Even before she really knew what sex was or any of the other dirty things two people could do to make each other feel good, part of her knew that there was no one she wanted to do those things with more than her older brother. He was a part of all of her most important memories -- always by her side, cheering her in victory and comforting her in defeat. He was her favorite person, and she just knew that having him inside of her, filling her up with his perfect cock, would be the most wonderful feeling in the world.

"Oh, please fuck me, John!" she begged. "I'm so ready to have you inside of me. I want it... no -- I need it so bad."

Her orgasm had washed away any sense of apprehension she might have felt as her brother nodded and pulled back, grasping the base of his cock and aiming it at her virgin opening.

Through all of this, Bill had been photographing his daughter, catching every moment of her sexual initiation. The camera zoomed in close as the head of his son's cock moved up and down in his daughter's cleft, eventually settling at the base of her opening.

"You can put it in me," she said. "Just go slow, okay?" she said.

John nodded. "Tell me if it hurts."

Everyone held their breath as he lowered his hips and pressed the head of his cock into her virgin hole. The only sound was Emma's panting breath and the repeated click of the camera as Bill documented Emma's entrance into womanhood.

John smiled at the look of radiant beauty on Emma's face. Fucking his mom had been an incredible experience, but nothing could compare to the sense of connection he felt with his sister. She was slick and ready to fuck, but unbearably tight at the same time. It was hard for him to know where his body ended and hers began as every tiny tremble made her insides twist and squeeze him in the most fascinating ways.

He went slow, knowing how nervous she was. Emma let out a series of quiet yips, biting her lip as he made tiny thrusts into her unexplored depths, going a little deeper each time. Those noises quickly turned into yelps of pain when he reached a certain depth.

John stopped right where he was, his excitement turning to concern as tears welled in his sister's eyes.

"Don't worry, honey," Susan whispered. "It only hurts for a moment, then you'll feel better than you can possibly imagine." As she spoke, Susan reached down between her children's joining and caressed her daughter's clit, offering a subtle reminder of the pleasure to come.

The ever-present girth of her brother's hard cock was painful, but Emma knew her mom was right. Despite the discomfort, she wanted to feel him buried fully inside of her. Taking a deep breath, she smiled up at John and said, "I'm okay. Keep going."

Seeing the renewed certainty in her eyes, John let out an excited groan and pushed a few more inches into her, wincing as she cried out in agony. His first instinct was to pull back, but a stern look from his mother stopped him in his tracks.

Emma scrunched up her eyes and balled her fists as her brother stretched her cunt past anything she would have thought possible. Just like her mom had warned her, the pain was piercing and intense, but it faded quickly into a sensation of pleasant fullness. That feeling grew in intensity until the initial flash of discomfort was just a dull ache, lurking in the background of a kaleidoscope of new sensations. Seeing the worry on John's face, she flashed him a carefree smile, signaling that everything was okay, while locking her thighs against his sides, using what little strength she had to hold him steady within her.

"Give me a minute to adjust," she said as he twitched inside of her, sending tendrils of warmth throughout her body. "I've never felt so... full. It's like I can feel every part of you pushing against my insides." When she felt more comfortable, she pulled him in deeper. She was steady, but insistent, wincing occasionally as he filled her up. They held their breath as he went deeper and deeper, letting out a sigh of relief when she finally felt the faint tickle of his balls resting against her asshole.

They stayed like that for several long minutes as Emma adjusted to the feeling of deep penetration. John's face was a mask of concern, and she loved him all the more for worrying about her. She explored his body, rubbing and lightly scratching his back before groping his ass cheeks. Sensing that she was ready for more and unable to resist his own growing need, John moved his hips in slow circles, grinding his pubic bone against her clit.

Looking up into his eyes, she nodded at him. This time there was no fear, only her burning need to cum on her brother's cock. He slowly pulled himself back out of her, his shaft pink with the blood from her deflowering. Moving slowly, but deliberately, he slid back into her, giving an extra little thrust at the end, which made Emma squeal.

The room was silent except for the sounds of John and Emma's increasingly frantic moans of pleasure and the occasional click of the camera. Bill looked up from the viewfinder to make eye-contact with his wife. They shared a loving smile, neither of them quite believing what they'd set into motion.

Without getting too rough, John starting fucking his sister at a steady, deliberate pace. She squirmed beneath him, rubbing her nipples back and forth across his chest. Eventually, John lowered himself fully on top of her. Their considerable height difference made her nearly disappear beneath him, the top of her head only barely reaching his chin. Bill could see the lusty smile on her face as she pressed her cheek against his chest. John reached beneath her, and held her close, wanting to feel every inch of their skin touching as he thrust himself fully into his sister's body.

With her legs wrapped around him, Emma hugged him back. She was in complete ecstasy as he steadily fucked her. With each down thrust of his cock, more of her juices poured out of her and ran down the crack of her ass. Soon she found herself humping upward at him, leveraging her grip on his back to slam her crotch harder and harder against his cock, her pussy making wet squelching sounds as her inner lips formed an air-tight seal around his girth.

Sensing that she was close, John picked up the pace, countering her thrusts with equally powerful lunges of his own that made their bodies slap together, drawing animalistic grunts from their panting mouths. Emma's groans quickly turned into shrieks of overwhelming pleasure, and a deep flush covered her face as she neared her peak.

"Nnnggghhhh! Oh Fuck! OH FUCK JOHN!" she screamed, completely overwhelmed with passionate love for her brother.

Sensing her imminent orgasm, he started grinding against her hard, putting pressure on her clit with each thrust.

"Cum for me, Emma," he whispered to her. "Cum for your big brother. Show me how much you like getting fucked."

John wasn't sure where that last bit of confidence had come from, but he sensed that it was just the push his sister needed to slip headlong into another brain-melting orgasm. Emma's eyelids fluttered as she gripped his shoulder-blades, holding on for dear life. Sucking in a deep lungful of air, she felt her sense of control slip away once again. This orgasm was quiet, but intense. Her whole body shook uncontrollably as her muscles strained against her brother's body. She could feel her pussy pulsing and straining against his invading member as her fluids poured out from around their joining, her entire world shrinking down to nothing but her brother's hard cock and the lightning bolts of pleasure that shot through her every time it bottomed out inside of her.

Eventually, her grip loosened, and she felt herself sinking back into her mom's lap as a wave of sublime happiness washed over her. Fucking her brother had been one of the most enjoyable experiences of Emma's life, but she knew it wasn't over yet. More than anything, she wanted to feel his cum filling up her pussy, and she was willing to do whatever it took to make that happen.

"Keep going, John," she begged. "I want you to cum, too. Make yourself feel good in me, just like you did with Mom."

He groaned and started fucking into her with long, steady strokes. Reaching between them, he lifted the hem of her teddy up to her neck, devouring her little titties with his eyes as he watched her nipples wobble back and forth on her chest with each violent thrust.

"Mmmm yeah. I never knew it would feel so good... having sex... fucking," she hissed between panting breaths, reveling in the look of abject lust on his face as he thrust in and out of her. "I'm all yours, John. This pussy is yours. Whenever you want it -- however you want it. You don't even have to ask. Just bend me over and fuck me. It's all I want... All I need... To feel you on me... In me... Fucking me... Filling me up with this perfect cock..."

That did it. The total conviction in her voice as she promised to be his personal cum-slut was more than he could take. With one last groan of relief, he buried himself deep inside Emma's cunt, holding himself there as he bathed her womb with his semen. He held her tight, making sure every drop of his slimy spunk reached its intended target before he finally collapsed, feeling utterly deflated.

They stayed that way for a long time, panting and sweating as they tried to regain some semblance of themselves. Emma sighed when her brother finally rolled off of her, shivering at the sudden feeling of cool emptiness as his softening cock slid out of her.

Standing on wobbly knees, John stared down at his sister's limp body. Her normally pale flesh looked red and raw from the friction of their lovemaking, but what really caught his eye was her pussy. That neat little slit he'd had his eyes on all morning was nearly unrecognizable. Her sparse, blonde pubic hair clung wetly to her swollen outer lips, perfectly framing a cock-shaped hole at the base of her opening.

Bill stepped up close and took a few shots of her well-fucked cunt, catching the exact moment when his son's thick, runny sperm bubbled out of her, dripping through the crack of her ass and down to the couch below. Emma was too far gone to feel embarrassed at being so exposed.

"That was the sexiest thing I've ever seen, baby," he said as he took her hand and helped her to a sitting position on the couch.

"Thanks, Daddy," she mumbled, her eyes hazy and unfocused before zeroing in on his hard cock bobbing in her face.

He assumed that Emma would need a break after the hard fucking she'd just received from her older brother, but the sly smile on her face gave him hope that she wasn't done quite yet.

"Sorry to make you wait, Daddy," she said, reaching forward and wrapping her fist around his erection. "How do you want me?"

Bill's dick lurched in his daughter's hand, and he had to look away for a moment to stop himself from blowing his load right there and then. Watching his wife and daughter get fucked by his son was the most exciting thing he'd ever seen, and it was only the thought of giving Emma the same treatment that had stopped him from bringing himself off while enjoying the show.

Still, the question left him speechless. He'd imagined this moment so many times and in so many ways, but he never imagined the question being put to him in such a direct way. Fortunately, his wife came to the rescue as she so often did.

"Come here, sweetie," she said, sliding off the couch herself and guiding Emma to a standing position. "Want to do something that will make your dad go crazy?"

Emma gave an eager nod.

Susan smiled. "Good. This position always feels great for me, too."

With that, Susan guided her daughter down to her knees and turned her around, so her face was resting on the seat of the couch. Reaching below her, she tilted her daughter's pelvis upward, offering Bill another lewd view of his daughter's hindquarters. His mouth watered as another glob of cum slid out of her opening, gliding down the length of her split before dripping to the floor below.

"Sorry!" Emma cried as she pressed her knees together in an adorable but futile attempt to keep the rest of her brother's load from flowing out of her. "I didn't realize it would just, like... come out like that."

"Sex can be messy, but that's part of what makes it fun," Susan said, giving her daughter a reassuring pat on the ass. "We can clean up later. For now, just stay as you are. Your dad's loving the view."

"I really am," Bill murmured, entranced by the sight of his daughter's well-fucked cunt.

Looking over her shoulder, the flush in her cheeks deepened when she saw the look of animal lust on her father's face. That was when the reality of what was about to happen truly hit her. This wasn't just her handsome daddy. He was a man -- a man who needed to cum and was going to use her body to make it happen. Her heart raced with excitement as she prepared to fully surrender herself to him.

"You can fuck me whenever you're ready, Daddy," she said. "I feel so empty inside -- so ready to be filled up with you."

Bill blinked in surprise, hardly recognizing the sexual creature offering herself to him, but once the reality of the situation caught up to him, his sexual instincts took over. Positioning himself behind her, he slid home in one easy stroke.

Emma shrieked. "Ahhhh! So deep! Oh, Daddy! You're so deep up inside of me!"

Bill had never been with anyone but his wife, and he wasn't at all prepared for the sublime pleasure of sliding his cock up inside his daughter's tight crevice. Her pussy made a wet, burping sound as he pushed in deep. Emma giggled as another stream of her brother's cum leaked down her thighs.

Beyond any physical sensation, though, was the sheer fact that the girl on her hands and knees beneath him was his own daughter -- the sweet, innocent little girl he'd cared for ever since he brought her home from the hospital eighteen years earlier.

Reaching around her with one hand, he groped at her tits, pinching and pulling on her nipples through the sheer fabric of her teddy before frustration got the better of him, and he pulled the whole thing up over her head, tossing it aside. His other hand played between her legs, rubbing firm circles over her clit and enjoying the way her body reacted to his fingers touching her most private spot.

John and Susan watched in rapt attention, amazed at how Emma looked, paying particularly close attention to the way her small breasts swayed below her with the motions of her father's thrusting and how her firm little butt jiggled each time he bottomed out in her. Seeing the camera lying on the floor next to them, Susan grabbed it and started snapping photographs, trying to capture every moment of her husband as he mated with their daughter.

It only took ten or fifteen seconds of hard fucking before Bill felt that familiar tingle in his balls that signaled the onset of a powerful orgasm. He wished it could have lasted longer, but there was no way to hold back the pent up arousal that had been building within him since the four of them had finished upstairs.

"MMmmfuck! I'm gonna cum, Emma!" he growled.

"Give it to me!" she demanded. "I want it sooo bad, Daddy! Fill me up with it!"

His daughter's filthy talk was too much for Bill to handle. "FUCK! HERE IT COMES!" he yelled as he took one last thrust into her clutching hole. He held himself inside of her as he came, wanting her to feel every spurt as he bathed her insides in his potent fluids.

Emma's tummy did flip-flops as she felt her father's cock swelling and flexing inside of her. "Ohhhh yes. Ohhhh fuck yes!" she cooed as a sublime sense of utter contentment washed over her. When Bill finally finished, he fell back on the carpet, watching with stunned fascination as his daughter's pussy hung open for a second, followed shortly after by a flood of his semen sliding out of her and adding to the puddle on the carpet below her.

Susan snapped a few more pictures before setting the camera down on an end table and walking out of the room. She returned with a soft towel that she used to gently wipe at her daughter's tender cunt.

Once Emma was clean, the family sat in a circle, smiling broadly at one another. "This has been the best day of my life," Susan said. "I've been building it up in my head for months now, wondering every day what it would be like to fuck my kids. I don't know if I've ever been as nervous as I was getting up this morning, knowing what your father and I were about to ask of you. Now that it's all happened, I feel happier than I ever could have hoped. Is it safe to assume you all feel the same?"

"God yes," Emma replied. "I can't wait to do it all again... but maybe we better wait til later. I'm a little sore down there," she added, giving her swollen pussy a tender pat for emphasis.

"I feel the same way," John said, jumping into the conversation. "I always wanted a beautiful woman to be my first, but I never imagined that woman would be my own mom."

Susan smiled. "You're such a sweet boy. I'm glad that I was the one who got to take your virginity. This is just the beginning, though. There's so much more I want to show you." John's eyes widened in excitement as he tried to imagine what else she had in store for him. Would his mom let him fuck her in the ass like he'd seen Steve doing in the picture album? Would Emma?

"Don't get him going again, honey," Bill said, flashing his wife a playful smile. "We still have a family Christmas portrait to take." The kids groaned. "Don't worry, we'll do it quickly, but your mom and I want a few more pictures to commemorate the occasion."

Susan grinned at her children's annoyed expressions before rising to her feet and placing the camera back on the tripod. The rest of them arranged themselves in front of the tree while she set up the timer to take pictures every twenty seconds. Once everything was ready, Susan ran back to her family. Their first picture was traditional, with Emma and John sitting on the floor and their parents kneeling behind them, smiling at the camera. Other than their nudity, and the freshly fucked expressions on their faces, it was a totally normal family portrait.

Slowly, the pictures grew more intimate. First Susan draped her arms over her son's shoulders, resting her cheek next to his. Bill did the same with Emma. They kept changing poses, including several shots of the parents giving deep, open-mouthed kisses to their children. From there, things grew even more explicit.

Emma and John made out for the camera as they groped each other's bodies. Though his cock was still soft and not likely to recover anytime soon, both his sister and mother got on their knees in front of him and took turns bathing him with their tongue. After a few more snaps of the camera, the women switched and gave Bill the same treatment.

From there, it was a natural progression to mother and daughter kissing, tenderly at first, and later with more aggression. The camera caught several shots of Emma sucking on Susan's tits in much the same way Jenny had to her mother in the picture they'd seen earlier that morning.

After a few minutes of this, both women stopped and gave expectant looks to John and Bill. "Oh, fine," John mumbled. He knew exactly what they wanted, and while he wasn't as reluctant as he let on, he still wasn't crazy about his cousins seeing pictures of him being sexual with his dad.

Still, both men knew from experience that there was no sense in arguing and quickly embraced, making sure the camera got plenty of shots of their tongues gliding in and out of each other's mouths as they stroked and fondled each other's bodies and played with each other's soft cocks.

The family ended their photo shoot with one more group shot. This time, instead of being formal, they were all sprawled in a heap on top of each other, enjoying the afterglow of the day's activities.

"I don't know about you guys," Bill said. "But I need another shower." They all chuckled, because they were, indeed, filthy with each other's juices, sweat, and saliva. He turned off the camera and took it off of the tripod, bringing it up the stairs with him as they followed behind. He tossed it on their bed as they piled back into the shower. By then, it was late afternoon, and they were all pretty spent. They joked and played grab-ass in the shower and generally enjoyed each other's company, but no one had the energy for anything more.

After drying off, they put on fresh robes and snuggled up together in Bill and Susan's bed.

"So, where do we go from here?" Emma asked.

"Well, I'd like to get those pictures uploaded and have a look at them," Bill said. "I might start assembling some of the better shots to send to your aunt and uncle. After that, I'm going to take a long nap."

"That's not what I meant!" Emma exclaimed. "What I meant was what comes next... for us?"

"I know what you meant, sweetheart, but that's entirely up to you and your brother," he replied.

"Remember our ground rules?" Susan asked. "As far as your father and I are concerned, anything goes so long as you have a willing partner. Part of the turn-on for us is knowing that you two find us desirable. No one feels sexy all the time, though, so if you're ever uncomfortable with something that's happening or just not in the mood, say so and it will stop immediately and with no questions asked. As long as everyone's into it, though, you and your brother are free to do what you like with each other, or with us. Like I said downstairs, there's a lot more we'd like to teach you."

"What about nudity?" John asked. "I mean, I really, really like seeing beautiful naked women prancing around the house. Plus, won't clothes just get in the way of all the... other activities?"

Susan sighed and chuckled at her son. "I think nudity is fine. Just make sure that you have a spare set of clothes handy in case of unexpected visitors. We should probably also institute a policy of calling home before bringing over guests."

"Makes sense to me," John said.

"For sure," Emma agreed.

As the conversation wound down, the family went their separate ways for a while. Bill plugged the camera into his computer and started sorting through the photos, while Susan left the room to call her brother and fill him in on everything that had happened. John and Emma went to his room to try out some of their new gifts.

For several hours, the siblings just enjoyed each other's company as they sat on the edge of his bed and played video games together. He kept stealing glances at her as they played, hardly believing that the beautiful naked girl sitting next to him was not only his lover, but his best friend, too. His thoughts wandered back to what she'd confessed to him earlier that morning and how foolish he'd been in not noticing that the girl of his dreams had been with him all along.

"Are you happy, Em?" he asked. "I mean about all of this. Did it turn out the way you wanted it to?"

"What do you mean?" Emma asked.

"I was just thinking about what you said this morning -- about wanting to be with me. Did I live up to your expectations? Was it everything you imagined?"

Emma stared back at him for a moment, her expression blank before she reached over and punched him in the arm.

"Hey! What was that for?" he asked.

"Don't be stupid," Emma replied. "Today was the best day of my entire life. I've wanted you for so long, but I thought I'd never be able to tell you how I felt. That would have been okay with me. As long as I had you in my life, I would have been satisfied. But having you here with me -- like this," she said, glancing down at his naked body. "It's so much better than anything I ever could have imagined."

John grinned even as he rubbed his tender shoulder. "I'm sorry it took all of this for me to realize how you felt. You do know that I love you, right? And not in a brother-sister kind of way. I was happy before, too, but I could never go back to the way things were. No matter what happens, I want you with me, just like you are right now."

Tears streamed down Emma's cheeks as she let out a desperate sob.

He scooted over to her and wrapped her up in a loving hug, feeling a flood of warm happy emotions as Emma melted into his loving embrace. Reaching down, he brushed away a tear before leaning down for a tender kiss.

"I love you too, John," she said, her voice strangled with emotion.

They stayed that way for a long time with Emma curled up in her brother's lap, sharing loving kisses and gently stroking each other's naked bodies. As time passed, their kisses took on a more passionate intensity, and having had a few hours to recover, John felt his cock hardening against his sister's thigh.

Sensing his arousal, Emma gave him a sly smile and pushed him down onto the sheets, exposing the object of her desire. His hard cock lay against his belly, and as she straddled him, she carefully arranged herself so that her wet pussy lips hugged the underside of his shaft. Her lubrication flowed over him as she ground her hips back and forth on his hardness. She loved the way her brother groaned helplessly below her, humping back up at her, desperate to feel her soft folds rubbing against his cock.

"Ohh... Fuck, that feels good, bro," she said. "I bet I know what you want."

"What I want?" he shot back. Grabbing Emma's slender hips, he slid her hips back and forth, drawing his shaft through his wetness and making her groan.

"Ugh, I hate you," she replied with a sarcastic smile as she slid back and forth in his lap, her pink nipples hardening on her chest as she coated her brother's cock in her arousal.

John caught movement out of the corner of his eye and turned to see his naked mother standing in the doorway to his room. One hand was massaging her left breast, while she fingered herself with the other. Her eyes went wide and a half-guilty expression came over her as she realized she'd been caught. "Um... Do you mind if I watch?" she asked.

Emma turned to look at her mother, grinning at her deer in the headlights expression. The utter strangeness of the situation soon had all three of them giggling, the sound of which soon drew Bill to the scene as well. He wasn't sure what to make of the situation, and the look of confusion on his face made them laugh even harder.

"Would anyone care to explain?" he asked when their amusement had died down enough for him to be heard.

"No, not really." Susan replied, still chuckling. "Besides, there's much more interesting things going on in here."

"Come on in," Emma said, smiling at her parents. As much as she was enjoying her special moment with John, having her parents there to watch added a layer of forbidden excitement to their coupling that she couldn't resist. Susan and Bill sat cross-legged at the end of John's bed, smiles of anticipation on their faces as they prepared to enjoy the show.

Emma resumed her grinding. His cock had softened slightly, but the warm presence of her pussy brought him right back to full hardness.

Raising herself up on her knees, Emma placed the head of his cock at her entrance and slowly sat down on his shaft. The feeling of her pussy giving way for his cock was exquisite for both of them. Although John was more than ready to fuck, Emma's pussy was still tender from the loss of her virginity, and she winced as she felt her brother's thick shaft push back up inside of her.

After several deep breaths, she smiled down at him. From his angle below her, John could see their joining. The sight of her small pussy lips stretched around the base of his cock was almost too much to take.

Tracing his eyes upward, he was taken aback at his sister's beauty. He knew she was insecure about her body, but he thought she was flawless. She gasped as he traced his fingers up her flat tummy and toward her breasts. He moved his fingers in slow circles around them, working his way closer and closer to her engorged nipples and driving her wild with lust. When he reached the center, he tweaked them with his thumb and forefinger, making her shudder and bear down on his cock. Her pussy rippled along his length, sending pleasurable shockwaves through his body. He caressed her cheeks and looked into her wide, green eyes, marveling at how his cute little sister had transformed into a sexual goddess right before his eyes.

The look of boyish excitement and lust on her brother's face made Emma's pussy swell and pulse around his shaft, easing her discomfort with each passing moment. Using her knees as leverage, she rolled her hips in a circular motion on his cock, mewling as her clit ground against his pubic bone. John liked the way his sister took control of their love-making. It was less animalistic and intense than their first fuck, but that was nice in its own way. They both had time to simply enjoy the closeness of the person they loved most in the world. John wished it could go on forever.

With each sway of his sister's hips, he thrust himself harder into her, feeling more and more of his cock slide in and out of her pussy. Eventually Emma rose up on her knees until just the head of his cock was still inside of her before slamming herself back down in one swift motion, causing both of them to let out excited cries.

Emma's ride on her brother's cock picked up speed until she was properly fucking him, her hips a blur in his lap. "Oh, bro, you have no idea how good it feels to have that thing sliding in and out of me," she said between panting breaths. "Can you feel how wet and hot I am for you?" John could not only feel it, but see it and smell it, too. On her up-strokes, he watched her lubrication cover the exposed part of his cock as it dripped down and matted their pubic hair.

"Mmpf, you feel so good, Emma. I love the way you fuck me," he said. "Don't stop! Please don't stop!"

They felt the bed shift and heard their mother let out a sexy moan. "Oh, honey, look at your beautiful daughter take that cock," she said. "Look at how wet she is for our son. Our kids are fucking each other, and we get to watch!"

Craning his neck, John could see that Susan had planted her feet on the floor and was leaning on the bed, supporting herself with her elbows while Bill fucked her hard from behind. From Susan's vantage point, she had a magnificent view of her son's cock sliding in and out of her daughter's cunt. John, for his part, enjoyed the view of his mom's tits jiggling and rubbing against the sheets while his dad fucked her.

Wanting the same view her brother was getting, Emma dismounted and turned around before sitting back down on it. John took the opportunity to grope and squeeze her ass cheeks, a sensation Emma found surprisingly pleasurable.

The sight of her parents fucking like animals in front of her combined with the feeling of her brother's warm cock sliding in and out of her pussy was too much for her, and she felt the familiar sensations of an oncoming orgasm. "OHHhhhh Yes! Fuck me, bro!" she grunted.

"Fuck, sis, your pussy feels so fucking good. It's so tight!" He grabbed her hips and started forcefully pulling her down on him, trying to stuff as much of himself inside of her as possible.

His forceful thrusting pushed her over the edge. "Oh fuck, bro, I'm coming!" she wailed. "I'm coming on my brother's cock!" She collapsed back against his chest, writhing and squirming through her intense orgasm. Waves of warm pleasure pulsed through her body as John palmed her breasts and held her in a tight, loving embrace. Her pussy felt like liquid fire, and he could feel her lubrication flowing out of her as he plowed into her twitching cunt.

As his sister recovered, John scooted back against the headboard, dragging her with him as she sat in his lap, his hard cock still embedded deep inside of her. From that angle, he had a good view of his parents as they kept up their vigorous fucking. Susan and Bill were delirious with pleasure and their attention was laser focused on the sight of their son's cock splitting open their daughter's pussy. Susan met John's eyes and gave him a lust filled smile. Her husband's frantic thrusting was getting the better of her, and she wasn't sure how much longer she could hold back her orgasm.

John loved watching his mom get fucked. The sound of their skin slapping against each other made his still-hard cock jerk inside of his sister's pussy.

Susan crawled up on the bed, sighing at the feeling of emptiness as her husband's cock slithered out of her. John and Emma's legs were spread wide, and she positioned herself between them. John groaned in pleasure as she leaned forward and licked from his balls, up his wet shaft and ending with a swirl on his sister's protruding clit. Emma let out a shriek and jerked on top of him, her pussy still extremely sensitive from her recent orgasm.

Susan let out a guttural moan as Bill followed her onto the bed and buried his length back inside of her. Regaining her focus, Susan returned to her son's cock and balls, occasionally sucking them both into her mouth. The feeling of her tongue swirling around them combined with his sister's tight pussy holding him like a glove had John ready to pop, and he groaned loudly.

Emma really wanted to get her brother off, but her tender pussy just couldn't take anymore hard fucking. Sighing in disappointment, she rolled off of him. "Sorry bro, that felt amazing, but if we go much longer, I won't be able to walk straight for a week."

"That's okay, sis," he replied, trying to hide his disappointment. She gave him a quick peck on the lips and moved to the side, giving their mother full access to him. From the side of the bed, Emma also had a better view of her dad fucking their mom. She looked on enviously at her breasts as they jiggled with each thrust of his cock.

Susan smiled up at her son. "Now it's your turn," she said. "What do you think, Bill? Should I reward our son for taking such good care of his sister?"

"Would you, Mommy?" he asked, playing to her fantasy. "Would you help me cum? I think you're so pretty, and I love the way you make my cock feel with your mouth."

"I think you should," Bill responded, playing along. "Isn't that what mommies are for?" All the while, he kept thrusting in and out of her, feeling her pussy swirl and tighten around him as they talked dirty to each other.

Susan was in a sexual fog, but rather than immediately devouring his cock, she pushed her son gently but firmly off of the bed.

"Trust me," she said, sensing his confusion.

As he stood by the bed, Susan flipped onto her back, temporarily pulling away from Bill's cock. She scooted so that her shoulders were even with the edge of the mattress. Supporting her head with her neck, she gave her husband the come-hither motion. He climbed back on top of her and went back to work between her widespread legs.

Since she wasn't facing him, John couldn't figure out how she was planning on sucking his cock. His confusion disappeared as she let her head hang upside down off the side of the bed. She smiled up at him as her curly red hair hung down to the floor. She opened her mouth wide and grabbed his hips, pulling his cock into her mouth.

John stepped forward and fed her his cock. Fucking her like this felt different from her previous blowjob. The angle made it much easier to take deep thrusts into her throat. He held back a bit, nervous that he might hurt her. Sensing his concern, Bill reassured his son.

"Go ahead, son. Fuck her. All she's been talking about for weeks now is how much she wants your cock down her throat. Give your mom what she needs." Susan groaned in agreement and sucked him even harder. All the while, Bill kept fucking her. The wet squelching sounds of their cocks pounding her holes and Susan's moans of delight filled the room as they spit roasted her.

John found himself face to face with his dad, and this time, they didn't need any encouragement to lean forward and press their lips together in a passionate kiss. Susan let out a guttural moan around her son's cock. From her position, she couldn't see what they were doing, but she could hear it, and the mental image those sounds produced were more than enough to push her to new heights of arousal.

"That's so fucking hot," Emma said. She had recovered somewhat and was leaning against a stack of pillows. Her pale skin was flushed and the lips of her pussy were still red and swollen. She felt physically worn out, but not too tired to enjoy the show. "Play with her tits!" she demanded, eliciting another anticipatory moan from Susan.

John did as he was told, pulling away from his father to look down at Susan's freckled breasts as they swayed back and forth with the motion of their fucking. Grasping one in each palm, he gave them a squeeze before zeroing in on her swollen nipples. Taking them between his thumb and index finger, he gave them a firm tug, drawing them away from her chest. She let out a muffled scream as she arched her back to meet his exploring hands.

Their fucking grew more frantic as they neared their respective climaxes. John had already been on edge from his session with his sister, and he was the first one to let go.

"Oh god, Mom, your mouth feels so good, I'm gonna cum!" he bellowed. She redoubled her efforts, sucking him hard and deep into her throat, suppressing her gag reflex as she repeatedly swallowed him. John groaned as he unloaded spurt after spurt of hot cum almost directly into her stomach, amazed at the feeling of Susan's throat as it milked him dry.

The volume was apparently more than she had been expecting, and she gently pushed him away, cum leaking from the corners of her mouth. He kept cumming, landing several more streaks of his sperm on her face and tits.

The feeling of her son's hot cum in her mouth and on her body sent Susan over the edge. "Ohhhhh, baby, yesssss... Your cum tastes soooo fucking good!" she moaned, loving how slutty the words sounded coming out of her own mouth. She thrust back against her husband's invading cock with desperate urgency, quickly losing herself to the filthy reality of what her husband and son were doing to her.

"Oh, baby, you love your son's cum, don't you? Does he fuck your throat as good as you hoped?" Bill teased, talking her through her orgasm before sliding over the edge himself.

"Oh, FUCK!" he exclaimed, thrusting in deep and holding himself inside as he shot another load of hot cum into her womb. He pulled out at the last minute and shot a few spurts on her gaping pussy and belly. Bill loved fucking his wife, especially now that they'd added this extra dimension to their lovemaking.

Susan felt like a wanton whore, and she looked like one, too, as she lay on her son's bed, covered in cum. She felt completely satisfied and blissfully happy that she could finally express a side of herself that had been buried down deep for so long.

"Mmmm, I love my men," she said after recovering a bit. "You both made me feel so unbelievably good." Summoning her last bit of her energy, she rose from the bed and made a quick trip to the bathroom to clean herself up.

They all relaxed in the afterglow of their impromptu family orgy, sharing loving smiles with one another.

"Well, this has been one hell of a crazy Christmas," Emma said.

"And it's not over yet. I've still got one more exciting present to share," Susan replied as she came back in. "I was talking to your Aunt Sally and Uncle Craig while you two were playing video games and filled them in on everything that happened. They were so excited to join us that they decided to change their holiday plans and come visit us tomorrow."
