Samuel Scarsdale had just lost his virginity to his sister, in front of their parents. His body was still tingling with endorphins, and his extremities trembled. He’d never felt anything like this before, and if he never got to feel it again, he would die. He knew he would be chasing this high for the rest of his life.

He wanted to rut Samantha again and again and again… later. Right now he wanted to rest, to lay down with the beloved twin sister who was currently on her back beneath him, and to rub his whiskers into her soft yellow belly fur. She looked up at him with admiration in her eyes; she was panting too. (But why, he thought. He’d been the one doing all the moving.)

But it seemed their mother had other plans. "Did that feel good?" asked Nilly Scarsdale, the family matriarch. She was sitting on the sofa with her husband Static, enjoying the show of her kids rutting on the futon. Enjoying it far too much, in fact, to let the fun stop just yet.

She got up off the couch, regretfully leaving the embrace of her lover, fingers lingering on his arm before the connection broke. Then she crossed to the futon and gave her son a warm hug. "Did you enjoy cumming in your sister? Why don't you pull out now so you both can see what you did." This was still a lesson, after all, and she was curious how they'd react to seeing their first cream pie up close.

Samuel was only able to nod a response out to his mother's questioning. Having just experienced his first orgasm (and his second almost immediately after), his poor body was in all sorts of euphoric bliss. Even the slightest movement made him tingle to such an extreme that he couldn't speak without becoming a moaning mess. But, he had taken the first step toward manhood today - and future parenthood, if he inherited his father's virility as well as he’d inherited his sex drive. Either way, that was cause to celebrate.

He pulled himself free of his sister's delectable, still clenching cunt. The sound of air escaping, along with the slosh of his fresh, hot cum oozing from her now open vaginal canal filled the room, easing up the silence as both parents and child awaited the sight of Samuel and Samantha's first creampie together. The seed was a pearly, shining white; its smell was strong enough to drown out the scent of Samantha's now deflowered maidenhood, a sign of its virility and potency. Not only that, it was thick, creamy even. It held its form together and didn't become runny or watery as it slowly trailed out.

Static too got off the couch, taking his position behind the rest of his family and bending down, hands on his knees and admiring what was, to him, one of the most beautiful sights in the world. "Man, talk about being my son, alright. He's definitely got a breeder's set of balls he's workin' with, eh honey?"

Nilly had set this up so that her kids could be amazed by their first creampie... but she was the one who ended up captivated instead. It was, in a sense, the perfect creampie, and she couldn't be prouder. Seeing the thick seed oozing out of Samantha's cunt, Nilly couldn't help but imagine that same seed inside her, and as if by instinct, her fingers crept to her cunny to finger herself. It was well past time for the parents to get in on the action, and she needed her son's cock now. "There's no question about that," she told Static. "The only question is who will get the most of that cum. You're going to have to fight everyone else for it."

Samantha craned her neck to see what they were all gawking at. "Oh my god," she said. "That came out of Sam's penis?"

Nilly helped her son sit down, no doubt rocked to his core by such an orgasm. And then she took his place between her legs. "That's right," she told her daughter. "But only because you made him feel so good." Then she took Samuel's place, kneeling down at the foot of the futon, and she began to lick the cum out of Samantha's snatch. Samanatha gasped and moaned as she gave the boys of the family a fun new show.

Static smirked as he watched his wife start to engage in the action with Samantha. He knew just how well she could use that tongue of hers, and if Samantha's moaning was any indication at all, there was no way she was going to be able to hold in any form of orgasm for long. She was in good hands, er, tongue. 

Samuel was still a bit out of it, but seeing his mom eating out his sister made him stare (and his spent dick gave a meager twitch.) He had never thought that an act like Nilly was doing was even an option; he surely had a lot to learn from her.

His eyes drifted down to his mom's thick ass, and he could only watch in amazement as it waved in front of him. It was hypnotizing. All he could do was stare into it, completely mesmerized by how she swayed it back and forth. It was like she was taunting him. Her pussy was leaking plenty of her juices too, further demonstrating her excitement.

Static caught him staring. Any normal father might feel outraged or threatened. But this family knew the value of sharing. He nudged his son to get his attention. "You admiring your mom’s cunt? Go for it, buddy. Be aggressive," Static whispered.

Turns out, that was all Samuel needed. He watched Nilly lavish Samantha with affection, paying close attention to her motions. Then once his overwhelming sensitivity to stimuli returned to a manageable level, he stood back up and gently gripped Nilly's asscheeks before diving his face in between them, his muzzle attaching right to her cunt as his tongue began to explore her succulent folds.

Nilly gasped as Samuel grabbed her asscheeks. She should have expected this from him. He was his father's son, after all. But even if she had expected that, she wouldn't have expected his sudden oral assault on her moist folds. And he was doing such a good job too, even after seeing her demonstrate on Samantha for a matter of seconds. Her whole body shuddered. "Ooh, just like that, baby..."

Nilly already had her hands full dealing with one sexually aggressive male. If she had to deal with two, it would be a full time job to keep them from knocking her up. 

Static was so proud of him. It helped that he was getting his own private show. "That's it. That's a good family bonding experience~" but he wasn't the only child who deserved to get some practice in. "As for you, Samantha, dear. Will you be Daddy's good girl and suck his penis till he fills your mouth with his sperm?" He maneuvered himself so that he stood over her face, his lengthy and girthy cock waving just on top of her muzzle and nose. His musk and scent of virility wafted down towards her nostrils.

Samantha did her best to pay attention to her father's commands, even as Nilly's licks sent shivers up her spine. "Okay, Daddy~" She grasped his cock in her hand and guided it to her lips. Her movements were jerky and uncoordinated, his scent stirring her arousal to even greater height. She kissed the tip, and finding the taste agreeable, opened her mouth to fit more of it inside.

Static reached down to pet his daughter's head. His big hands nearly eclipsed the size of her head, making it easy for him to ruffle up her hair, or grip her gently and guide her down his meat pole. "That's it... that's a good girl~" He cooed out, giving her gentle words of encouragement as she worked her way down his cock. He was by no means an easy amount to swallow, yet she was making good progress in slowly taking it down the back of her mouth, little by little. "You've definitely got your mother's mouth on you, sweetie. You're gonna make Daddy a proud Papa~"

Hearing Static's words of encouragement, and feeling his large yet gentle hands show her affection, Samantha knew that she was doing a good job. She wanted nothing more than to make him happy, to make memories that they would all enjoy and look back fondly on. She couldn't talk with his dick in her mouth, so she hummed instead, and she tried to fit more of his cock inside her. His feline barbs brushed against the top of her mouth in a way that tickled, and she made eye contact with him as she slowly worked the dick, a fraction of an inch at a time. It looked unlikely she would be able to take the whole thing right now, but with enough practice, who knew?

Meanwhile, Samuel continued his rapid assault on Nilly's slick cunt. Her enthusiasm had spurred him to continue his tongue-work and try new things. He flicked his tongue across her clit in a curling manner, followed by a jab as if he was pushing a button into a socket. While he didn't have the experience to quite pull it all off, he had a general idea in his mind of what to do and when to do it. With some fine tweaking and more experience under his belt, there was no doubt that he'd be just as good as his father was in bed.

There was no way Samuel was new to this, thought Nilly. He had to have been practicing. Or maybe he was just that creative to figure out he could do these things with his tongue all on his own. Her hips bucked, and her kegals twitched. Her body ached for something to penetrate her, be it Samuel's tongue or his cock.

She distracted herself from her son's assault on her sopping nethers by taking Samantha’s young tight pussy lips into her mouth and suckling on them. This in turn made Samantha squeal around her father’s cock.

The daisy chain of lions was a perfect show for Static. He watched his wife get double teamed, curious how long it would be before she buckled and begged for cock. He wanted to see his own flesh and blood breed her; the next best thing to doing it himself (and he had to admit it was naughtier.)

"You sure you can handle that tongue lashing he's giving you?" Static teased, smirking over at his wife as he watched her body spasm in uncontrolled bursts. 

Nilly recognized her husband's teasing for what it was: "If I can handle you, I can handle him," she shot back. 

“Can you handle me?” Static challenged. "Or him? At this rate, you're gonna pass out before the kids do~" His voice was playful, and the entire time he teased he was stroking his fingers through Samantha's hair. His affectionate pets and little blow kisses of encouragement really cemented the close relationship the two had with each other. And now that they were getting to be intimate, it was only going to get closer.

Nilly removed her head from her daughter’s crotch to retort, "How about you you just focus on fucking our daughter and let me handle our son? Her mouth must be heaven right now."

Heavenly was certainly Samantha's goal. From her place between Static's legs she had a great view of his crotch and balls, and she reached out with one hand to cup them, even as she slowly worked her mouth toward the base of his cock.
“It really is heaven,” Static agreed. “Our girl’s a natural. She’s going to make us so proud.” Both parents understood how essential being good in bed was to getting ahead in life. The family business was in good hands for sure.

By now, Samuel's body had rested enough that he was raring to go again. Even though he just lost his virginity, his body still knew what to do in a situation like this. His cock began to sprout back up, and slowly but surely he became erect again. He even had a small, shining glob of pre waiting on the tip. While he was still face-deep in his mother's cunt, his cock throbbed, ready to impale a hole and deposit another load of his virile and potent sperm. 

"It's OK, Samuel. Go mount your mother~” Static encouraged. “Make love to her while I give some attention to my darling girl.” His hands caressed Samantha's cheeks. Her movements were already starting to remind Static of her mother's. So long as she kept getting experience with the family, she'd end up just like her mother, in terms of sexual prowess. 

Nilly focused her efforts on Samuel. She hooked her arms around his shoulders and laid back on the couch, pulling him forward. "What do you think?" she asked him. "Do you want to see how Mommy's cunt compares to your sister's?"

Samuel gave his mother a slow nod. Things were moving so quick, but he was content; this all felt so right. His dick throbbed against his mother's folds, ready to penetrate and deposit his own child into the place where he himself came from. "Y-Yeah! I wanna see how Mommy's pussy feels... and I wanna let all of it out inside her too…~" He could feel the tip of his cock gently graze his mother's pussy, nearly slipping in. There was a blissed-out look on his face. 

Nilly loved his enthusiasm, and she chuckled. "Hold on, stud," she told him. "There's one rule that we haven't really covered yet. It's naughty to let it out inside a girl without her permission, you hear me?"

The sudden stoppage caused a little bit of recoil in Samuel. His eyes and ears were at attention as his mother explained the new rule that hadn't been said yet, but once the word "naughty" was heard, he understood immediately.

Naughty was a word that had a special meaning in this household. It meant that it was something that could get you in trouble in the outside world if you got caught doing it. And it was something that the family promised not to do to each other (well, unless it was all in good fun.) But it was also something that the parents rewarded the kids for, if they could do it without getting caught. So stealing was naughty. Cheating was naughty. And knocking up someone who didn't want to be knocked up? That was definitely naughty... not that it stopped Static from trying on occasion.

But even as Nilly wanted to convey the seriousness of insemination, she also wanted Samuel to be conflicted, teased, on edge. So even as she explained this she grabbed his cock and rubbed it against her folds. "I like to make my boys earn a creampie. If you can't handle that, you'll have to stick with fucking your sister."

"I-I'll earn it, Mommy~" He promised, a small purr coming from his throat. He was twitching, and globs of precum were starting to drip from his tip in anticipation for the main event. Samuel understood the rules. But he still had so much of his father in him, so all he could think about was how he could start getting away with naughty things in the household. If he could find a way to skirt the rules, he would.

Nilly anticipated a bit of deceit from her son: she expected no less from a family of criminals and criminals-in-training. But if he wanted to pretend to obey, she’d play along too. It was an intricate dance, full of subtleties and subterfuge, and it was by far her favorite game to play. And she was good at it too: Nilly was confident that she could handle whatever Samuel threw her way, and she was honestly excited to see what he came up with. A certain amount of naughtiness in the household was not only to be expected, but much enjoyed. 

"I know you will," she told him. "Go ahead now, show Mommy you can set a good rhythm..." She was so close to something she'd dreamed of for over a decade, and now it was finally here. She needed her son inside her. She did her best to not show it, but inside the wait was killing her. She just needed him to fuck her already. 

Samuel nodded at his mother. His cock continued to graze against her pussy, tugging and pulling due to the barbs with every thrust. He took one deep breath to ready himself, making sure to line his penis up just right, and then he took the plunge. 

Nilly squealed, a crazy wail that revealed her total loss of inhibitions. Her body reacted to his primal touch, her insides squeezing him tight, forming a tight suction seal. And a second later, it was done. One loud schlick and a hearty moan from the boy signaled what had happened. His cock was inside his mother's cunt, her wet insides wrapping around him like a vice. He immediately could feel a difference from his sister's pussy. Nilly's twitched and milked at a much faster pace, almost as if it had a mind of its own volition. At first it felt like he might not even be able to do much, but after a few seconds he managed to collect himself and start thrusting slowly.

The sensory overload that was overtaking Samuel still nearly made him lose control every second, but he did his best to keep that edge away, even if it was just for a little bit. He wanted to prove to his mom that he could have sex. He wanted to be naughty, he wanted to shoot his cum inside of her. Those were the only thoughts going through his innocent little mind right now; all to feel good and make momma feel good too.

While Samuel found a rhythm within his mom, Samantha was in the zone, purring softly as she nursed her Daddy’s cock and he caressed her soft body. Her purring created pleasurable vibrations up Static’s dick. Her eyes were closed and she breathed in his musk as her head continued to bob up and down, his barbs now touching the back of her mouth.

The rather vocal sounds of moaning and groaning and fucking from right next to them finally got her attention. She popped the cock out of her mouth and took a moment to watch them. Mindful of her father, she continued to jerk his cock with a free hand.

Static had a good idea what was going through her mind, and how to prod her in the right direction. “What’s wrong, Sweetie? Do you not like how Daddy’s cock tastes?”

“It’s not that… they look like they’re feeling really good.” Samuel was the more audible of the pair; his mind was at such a complete loss to describe the new feelings coursing through him that he was falling back on savage moans. But Nilly was clearly feeling good too: despite her attempts to maintain her composure, despite her focus on the task at hand, her body was melting from the pleasure.

“I bet they are,” he agreed. And then he asked the question he’d been dreaming of asking for years. “You want to do it too? You want Daddy to fuck your tiny little pussy, baby?" He smirked down at her, petting and playing with her hair. He had been waiting for this day. The idea of fucking his own daughter, creaming her pussy and making more kids had been his fantasy since he knocked Nilly up. Now, it was all right there for the taking.

Something inside Samantha hungered. "Yeah, I want you to fuck my pussy and shoot the white stuff in me." 

*God, she even calls it white stuff.* Static couldn’t remember if they’d told her any of the more grown up names for jizz, but hell if he was going to correct her now. She’d learn in time.

Samantha watched Samuel working up a rhythm with Nilly, who was on her back just like she was. "Do I have to be on my back?" she asked curiously. "Or are there other ways to do it too?"

Static would patiently answer all of her lewd questions. He would only get to teach her how to be this naughty once, after all. "Of course there are other ways, sweetie. Daddy can show you lots of ways. You like the dog boys from down the street, right? Daddy can show you how they fuck." He knew firsthand how they fucked, too. That had been a fun night.

A serious and composed countenance settled over Samantha. "Okay. Show me how to fuck like that.” That wasn’t a request, it was a demand. Samantha had a tendency to get laser focused when she saw something she wanted. It was sometimes a hassle between the father and daughter, but when it was something they both wanted, it worked out great.

Static smirked as he picked up his little girl and set her gently on her hands and knees. He took a little bit to adjust her pose: Getting her back arched properly, making a stand out of pillows so she was higher in the air to make it easier for him to slip inside, as well as warming her up by playing with her pussy and clit again.

Samantha trusted her father completely and let him pose her. The doggy pose was new and a little uncomfortable, but his minor adjustments helped; to her, it was just another sign that he cared about her and wanted her to feel pleasure. She gasped as her father's magic fingers ran over her sex, her entire lower half feeling tingly and warm. Her brother's cum still oozed from her snatch, dripping onto the pillows. Static felt so lucky to be getting a close up view.

Once he was finished setting her up, he laid his cock on her butt, letting the spittle and juices from his earlier escapades stain his daughter's tail and back fur. "This is called Doggy style, sweetie. It's very good when you want to fuck fast and rough. But it's also helpful for the white stuff, too. It lets it go deep inside of your pussy and into your womb~"

“Doggy style~” she repeated. She liked the sound of it. You know, those dog boys are pretty cute…" Then she got an idea. "If I wanted to, could I fuck with them too?"

That sounded so hot. Static imagined inviting the whole family over, taking their mom while Samantha entertained the boys. "Mmm... I don't know,” he teased her, despite already deciding it was going to happen. “We'd have to ask Momma if she wants puppies in the family. But I think it should be fine. Especially since you go to school with them." As he talked, he lined himself up properly, the tip of his cock pressing into the folds of his daughter's pussy.

Samantha peeked between her legs and got to see her Daddy's cock resting right at her entrance. "Puppies? What does puppies have to do with that?" She asked, her voice incredibly shaky. God, it was hard to think about anything other than getting rutted right now. She needed him to just stick it in.

"Don't worry, sweetie. Daddy and Mommy will tell you more about that after we're done,” Static promised. Then he gave it to her, slipping between her eager folds with a single firm stroke. Once he gave her some time to adjust to the feeling of an adult cock stretching her, he began to  cock pistoning out of her, his balls slapping against her legs. Gentle, but firm and powerful. He made sure to get deep, to rock her to her very core for her first time with her Daddy.

Samantha put her weight into her elbows to keep balance and steady herself as her daddy thrust into her. At first she looked down at the couch, too overwhelmed by the incredibly tingling feeling of fullness to do much else. Even though she'd already been fucked by her brother, this was something else. Static was bigger, and knew what he was doing to boot, pushing in deep and spreading her with his girth. Samantha's inner walls squeezed back on Static's cock: God, she was tight, and her pussy was burning hot. She moaned as he rocked into her, touching something deep inside her that sent a jolt up her spine and made her moan.

"A-Ah!" The sudden shout didn’t come from her, but from her brother, who was now recklessly pumping into his mother. Both Static and Samantha turned their heads to watch; Static could multitask.

Samuel looked like he was in heaven. "Hah.. M-Mommy's pussy feels... amazing~" He managed to get out, his tongue hanging from the side of his mouth.

"It feels amazing because it's the one you came out of," she told him. She could tell by his sudden faraway gaze that those words had struck him right through the heart.

"A-Ah... T-This is where I came from?" Samuel asked, barely able to edge the words out as he thrusted even harder into his mother's pussy. 

Nilly knew how to push her son’s buttons. He’d been doing such a good job before, but now he was breaking down from her words alone. Nilly looked at her son with love in her half-lidded eyes. "This is where you came out of Mommy," she confirmed.  "And now, you're back inside her and she loves you so much~."

Samuel's moans continued to burst out from his mouth without control. His gaze was focused purely on his mother and her rocking body. His thrusts started to become shorter, but quicker and with more power behind them. He was mustering as much force as he could in his tiny frame, desperate to fuck to his body's limits. His limbs shook, as the feeling of a coiling spring began to take place in his loins, the same feeling from when he had sex with his sister. "I love you too, Mommy, so much! Ah! I think... I think.. I'm gonna...!"

“You gonna cum?” Nilly teased her son. “Gonna shoot your load all inside Mommy? Have you earned it? Or are you gonna be naughty and do it without permission?”

Samuel didn’t answer the question; he merely groaned. “Please, Mommy… I’m really gonna cum!” He was trying to hold back for her, but it was impossible. Her insides felt too good, and he was a slave to his body’s desire to breed. He couldn’t stop it now, and the concept of pulling out didn’t even occur to him. Coitus interruptus was not a thing he’d been taught yet…

Nilly considered her options. She wanted to tell him to use his sister instead, but one glance was enough to show that Samantha's pussy was occupied at the moment. Oh well. Might as well embrace it. "Go ahead, baby! Fill Mommy up!" she instructed, pulling him in closer for a kiss.

Samuel tried to respond back, but all he could do was lean down to kiss his mother. His lips locked onto hers, his little body frantically pumping into her even as he tried to hold back his impending orgasm. Mother always knew best, and right now it seemed that was to give into his body’s demands. So he stopped holding back, and almost immediately he was pushed over the metaphorical edge. His cock spasmed, and pumps of hot sperm rushed from his tip and into his mother's pussy.

Samantha was in heaven too. The best part was how in this pose she didn't have to move, she could let Daddy do the work while she watched Samuel and Nilly. "Oh wow, look! Samuel's cumming in Mom!" she called out, pointing. "Is that what it looks like?" She couldn't really see it when it was happening to her, so that was the first insemination she could actually watch. "Are you gonna do that to me, Daddy?" she asked him. Her pussy held his cock like a vise, eager for his seed. The area between her legs burned with need, the pleasure washing over her in waves.

"Uh.. fuck yeah. Daddy's gonna do that to you, baby," Static promised. The short little thrusts he was making into her, steadily went deeper down her pussy. His cock throbbed, already wanting to blow his sperm into his daughter and fuck up the family tree. (Assuming that his son hadn't already fucked up the family tree by blowing his load inside Samantha, of course.)

Nilly laid back and enjoyed the ride as hot cum flooded her insisdes. She wasn't sure how she felt about getting pregnant again, but the thought of her son knocking her up was erotic enough that she decided to let it slide, this time. She held Samuel close, making sure that every drop went inside her. "Good boy," She praised. "You did an amazing job."

Nilly was never this enthusiastic about being creampied. She was almost certainly doing it to fuck with Static: she was always so careful about not letting him inseminate her, and then she spreads her legs for their son and lets him creampie her the first time? She was trying to make him jealous, for sure. But given that he got to watch such a hot show, could he really complain?

"Hah... I did good...~" Samuel managed to pant out. Every sense in his body was in overload, but starting to come down. Now all he could feel was the exhaustion starting to run its course across his entire body. His dick managed to stay hard, but that was about it. Muscles went limp, and his body crashed into his mother's body.  "Mmm... love you, mommy..~"

Nilly pulled her son's head in close, enjoying the intimacy. "You did great for your first time, but there's room to get even better. You came pretty fast... and you came inside Mommy. That's naughty, you know." She tapped him on the nose playfully to let him know that she wasn't actually mad. "I want you to practice with your sister every day, okay?"

Samuel nodded, and blushed from his mother's touch. He looked forward to waking up each day, now. If all of his future days were going to be like this, but with his sister? What else could he ask for? "I will... me and Samantha will... practice for you everyday~"

"Good boy," Nilly told him, stroking his back. "I have such amazing, wonderful, sexy children." Nilly was looking forward to seeing her kids fuck freely around the house, and thanks to their home security system, it would all be recorded.

Holding her son close, she laid back to watch Static go balls-deep in their kid. She couldn't believe her luck in getting to watch her husband potentially knock up their daughter; it made her feel less bad about playing so hard to get, now that Static had another female in the house to make babies with. She imagined the four of them doing this every night, Static breeding his daughter and Nilly breeding her son. Surely Static would have no complaints about that.

The force of Static's thrusts pushed Samantha into the couch. “Now, are you ready for Daddy to go faster? You want him to put his white stuff inside your vagina, right?" he murmured in her ear.

Samantha was loving the attention. "Please, Daddy," she begged. "I want it." The thought of carrying her dad's seed inside her warmed her heart. She'd carry it as long as she could, until it all dripped out~

"Well, if you're asking me like such a good girl, I guess I have no choice but to give it to you." Static gave in and gave his daughter what she wanted. His deep thrusts became even faster now that she started to adjust to his size. In turn, he could feel her tightening cunt clamp around his shaft with every pump of his hips. His balls slapped against her pelvis, the slap and audible sounds of her juices being sprayed everywhere on the floor. 

He groaned out. He could feel the growing pleasure starting to congregate in his crotch area, the all-too familiar feeling of a spring pulling back, ready to launch. "C'mon, ask Daddy for his sperm. Tell him you want it inside you like a good girl would." He whispered to his daughter, still fucking her silly, even as his orgasm began to approach. He desperately needed to hear his daughter begging for his seed inside of her. Her mother was always so picky about not letting him cum inside. Well, he'd make sure she shared no such tendency~

Samantha couldn't wait. She needed to feel his goo inside her. Just imagining it was pushing her up against the edge. "Give me your sperm, Daddy!" she begged. "I'll keep it inside me forever!"

That did it. "Oh, fuck. Fuck yes, baby. Daddy's gonna give you his sperm, now! Take it all and give daddy a nice surprise after it's all done!" Static shouted. He gritted his teeth as that load finally came free, pumps of semen gushing into his little daughter beneath him. 

Nilly and Samuel watched together as Static finally let loose inside Samantha, the father's balls clenching as he rhythmically unloaded. They both understand that they were witnessing something special, miraculous even, something that the outside world would never get to experience or understand.

Samantha felt each pump as it flooded her womb, her inner walls eagerly milking him as her body accepted his gift. She wasn't sure what the nice surprise was, but whatever it was, it sounded exciting. When he finished, she sat up so she could watch where cum was trickling out of her snatch: after getting her father's sloppy seconds, the mixed cum of both males was running out of places to go. She did her best to hold it all inside her by tightening her lower muscles, but thick rivulets of cum still leaked out.

Samuel caught his breath as he watched the dribbling remains of his seed mix with his father's and leak to the ground. The globlike mess was thick and had a pungent odor to it. Not that it was necessarily off-putting, just strong. 

"How was that, sweetie? Certainly looked like you were in love with Daddy the whole time." Static couldn’t help but fish for compliments after a good fuck like this.

Samantha couldn't find words at first, so she just nodded and hummed. "Mmhm. You and Sammy both felt so good. Promise me we can do this lots and lots?" She collected some of the dripping cum with her finger. She ran it between her fingers, wondering what it was all for. "You made so much sperm, Daddy. It's warm..." She popped it in her mouth and sucked it off.

"Daddy always makes a lot,” explained Nilly. “He eats healthy and takes lots of vitamins to make sure he has the strongest sperm out there."  She smirked, watching her young daughter begin to gobble up her father's semen. She shared a glance with Static and knew they were thinking the same thing: What a hot sight it was, her curious eating stroking a fire in them both.

Nilly bounced Samuel playfully in her lap. "You made a lot of sperm in your sister too,” she praised him. “I wonder whose will take."

"Whose will take?" Samuel asked, his head tilting to the side at his mother's verbiage.

"You'll find out soon enough."

Moments like this just reminded Static of how special Nilly was, and how lucky he was to have her as his wife. "I think Daddy and Mommy might need some special time, too."

Nilly had to agree with that. "Daddy's right. He's been such a good teacher today, he's earned the right to fill Mommy's pussy too. You two are more than welcome to stay at watch," she told her children. She booted Samuel out of her lap, pushing him toward his sister, then welcomed Static into her arms. "Thank you so much," she told him. "I know I tease you, but you're the best husband a pervert could ask for. Stake your claim in me, you stud. Compete with your son's sperm and let's see who wins."

Static smirked at his wife's words. A competition of who was most fertile? Surely she couldn't be serious. It was obvious to him who would win in such a game. But then again, if anyone could compete with him in terms of virility, it would be the fruit of his own loins. He was thrilled to find out. "You're the best wife a pervert could ask for,” he told her. “Always so loving, charming. And drop-dead fucking sexy too. No one can take you from me~" Not even their son, although he was going to love watching him try.

The bonded pair snuggled on the couch, Static making several love bites on his lover’s sensitive belly. 

Samantha welcomed her brother onto the futon. "Sex is amazing," she told him. "I can't believe we didn't know about this before."

Samuel laid next to his sister, sprawled out wide. His dick, which was impressive for his age but still not fully developed, had gone flaccid, completely spent for the day. "Yeah.. it sure is fun. I wanna do it again tomorrow... and after that too~"

Samantha leaned over and kissed her brother. "We will," she promised. "I want to do it with you every day." She was sprawled out too, taking deep breaths to recover her stamina.

In front of them, their parents commenced the third round to the night’s festivities… and then after that there would be a fourth, and then a fifth… At this point, none of them remembered that they were supposed to be watching the game on the television, and frankly none of them cared.

The twins, energized by watching their parents fuck, exchanged a hungry look. Samuel was already starting to get erect again, and Samantha reached down to feel it. He reached between her legs too, rubbing her folds. The two played with each other awkwardly while they watched their parents bang.

One thing was for certain: no one was going to sleep a wink that night.
