#1 of Furry Family Fucking

This first story is just one of what I'm hoping will turn into something of a collection of many short incest stories. I'm really into incest, but catch 22 is I can honestly say I'm not sexually attracted to anyone in my family. I know, right? But they just don't do it for me. But that's what rping is for, right? Because I know I'm not the only one. And that's part of the reason I wanted to write incest stories, knowing that I'm not alone. We all have secret fantasies, some darker than others. Hell, there are some that are darker than incest!!! But I don't judge, and I only hope you'll extend me the same courtesy.

Anyway, as far as my incest stories go, most of them will probably be about otters. Like this one! However very few will have any girl on girl. Sorry, bros, but to me, incest is hotter with a dude in the mix. But I do have lots of ideas for m/f/f type stories. I also plan to use wolves, foxes, huskies, lions and lionesses, horses and other species for all kinds of exotic incest fun. And anything I write with humans will contain an element of bestiality. You know, to keep things hot and furry :3

Oh! And there's something else I may write about that I feel you should know on the off chance you're not into it or have ethical problems with it. Cub incest. Yup. You heard me. Now, come on. I'm not a pervert and I hate pedophiles as much as anyone else. But furry cubs are just too yiffy sometimes. Don't worry, I would never do any of the dark, perverse things that my characters do, and for one simple reason: it's just plain wrong.

And please. I haven't written anything in a while, so please don't criticize so harshly.

Enjoy!


"Dude, I've never seen Bruce so pissed at losing," said Jen to her twin brother as the two young otters walked up the driveway to the house.

Being as they were twins, their physical attributes were nearly dead-on. They both had dark brown fur with beige muzzles and torsos, same short ears, same broad, black noses, and one's tail was just as long and thick as the other's. Aside from certain male and female body parts, their one physical difference was their eye colors. Zak's were a vivid blue and Jen's were a forest green. They shared a lot of traits personality-wise as well. They both loved the color black, listened to the same kind of music (hard-core rock and metal), and they both hated having to share birthdays, but that was something they just had to deal with. But their absolute favorite thing in the world? Soccer. The two otters loved sports in general and were absolute fitness nuts. But to Zak and Jen, there wasn't a more rewarding workout than playing (and winning, in this case) a good old-fashioned soccer match on a beautiful hot Summer's day.

Zak chuckled. "Yeah. The guy can't handle being outsported by a girl."

Jen looked at her brother and grinned as they approached the front door. "And having to pay us each $20 was the fucking cherry on top!" She had tucked her money between her boobs, which were a size C, but they looked bigger in her small black nylon sportsbra, which clung to her body in an ever-so-flattering way. "You got the key?"

Zak nodded, soccer ball tucked under one arm. He reached into the pocket of his shorts, which were also nylon, but looked baggier than they were, and pulled out the housekey and passed it to his sister, noticing the glare from the hot sun reflecting off her boobs via her top. And then, he noticed her tits, and a grin spread across his muzzle. She wasn't wearing a bra.

Nice.

Jen opened the door and walked inside, with Zak following behind her, his eyes now on her perky ass in those short, tight, black nylon shorts. He felt himself rising to attention, but it didn't bother him. Or Jen, for that matter. While the two had never done anything sexual together, they had spent their whole lives sharing a room and changing clothes in front of each other, so neither one had anything the other hadn't seen.

However, as far as sexual feelings go, Zak had only just recently started having them about his sister. It started when he first had a wet dream about her a few months ago, and instead of freaking out when he woke up, he just rubbed one out instead and went about his day. Now, whether she had any sexual feelings toward him, he had no idea. It's not like they had twin telepathy or anything. And, yeah, like most brothers and sisters, the two had walked in on each other masturbating several times. But instead of awkward silences or arguements, whoever walked in on who would just laugh, apologize, and walk out, never saying another word about it to anyone, not even each other. They weren't just siblings, but best friends.

Of course Zak had rationalized his desires, and decided that he'd probably never act on them. Besides, there were plenty of girls at school he could nail, and he had the charisma and sex appeal to do it with whomever he wanted. He just...didn't.

As the twins walked into the cool of the air-conditioned house, shutting the door behind them, they both looked around for signs of life from either their parents or their little bro Kaiden, but neither was around.

"Man, that feels good," said Jen, standing in front of the A/C vent. She ran her webbed fingers through her short headfur, then wiped the sweat on her sportsbra, looking almost as if she were rubbing her boobs. Zak watched without hiding it, as her eyes were closed, and silently enjoyed the show. As she wiped her sweat on her boobs, she was also slightly pushing them together, making it almost look like she was gonna pop out of her top. Zak leaned back against the wall, watched for a bit longer, then closed his own eyes and took a deep breath.

"What's up, bro?" Jen asked, her eyes now open and her hands by her side.

Without opening his eyes, Zak shook his head. "Ahh nothin'. Just picturing that awesome kick you laid on Bruce's goalie."

She chuckled. "Shit, that was nothin'! You don't play sports like we do and NOT bother to learn some awesome moves! Style counts too, bro!"

Zak chuckled as he opened his eyes and saw his sister grinning at him victoriously. Then he looked down and noticed that her tits had gotten hard from the A/C. Yet another sight he allowed himself to enjoy while it lasted. And before he allowed himself to look TOO long, he quickly made eye contact and tossed out a conversation-starter with a half-smile. "Did you hear what Don said after you won the game?"

Jen smacked her lips. "Yeah, that fuckin' comment about me bein' a lesbian? I was like, 'fuck you, bro, I'm bisexual!'"

Zak laughed. "You know that motherfucker didn't see that comin'! You see how stupid he looked when his jaw dropped?"

Jen laughed too. "Hell yeah!"

The twins enjoyed the aftermath of their win and walked over to the black leather loveseat in the living room and talked more about the cool and funny things they said and did on the field for several more minutes before turning on the TV.

Jen had the remote, and after a fruitless effort of channel surfing, she cursed aloud and said, "You can watch whatever you want. TV's nothin' but commercials anymore." And with that, she scooted toward her brother a bit, then turned sideways and lay back on the couch with her arms behind her head, propped her legs up on her brother's lap, and let her tail hang down to the floor.

It was poses like this that reminded Zak just what a tomboy his sister was, and he loved her for it. If he had had one of those super girly sisters that took forever in the bathroom and hated sports with a passion and always cared what all the popular girls at school thought of her, that bitch would've ended up dead.

His whiskers twitched a bit in response to the thought. If THAT kind of girl had been his sister, then who would've caught bugs with him when he was just a pup? Who'd play video games with him? Who would he play soccer with? Who would--

--Have tits like that worth looking at while he wasn't being watched?

Sure enough, his eyes had made their way there. And Jen was too busy doing something on her phone to notice. Oh well. At least Zak didn't feel disgusted with himself for staring, or for all anyone knew, he'd have commited suicide. Of course he knew it was wrong, but after a while, he had stopped caring and started letting himself like it. Besides, he had a thing for tomboys. And it wasn't his fault that his own sister was exactly the kind of girl he liked in each and every single way.

Suddenly, Jen adjusted one of her legs, and that was when Zak had noticed just how hard he was, how hard he had made himself thinking about his sister.

Oh well. She didn't notice his boner, and hadn't taken her eyes off her phone, so...

Zak adjusted himself where he was sitting and allowed his dick enough room in his baggy shorts to flex and throb as much as was needed. After a moment, he started to get hot again, so he set the soccer ball on the floor next to the loveseat and pulled off his black tank top, catching a whiff of his armpits as he removed the garment. One of the things he loved about the special relationship he shared with his sister was that his musk didn't bother her, and hers didn't bother him. In fact, on those days where her aroma WAS particularly strong, it acted as an aphrodisiac to him, as it were.

Of course, that didn't weird him out either. After all, it was only a natural thing that a female's scent would be considered enticing by a male, blood bonds be damned.

Yeah...damn'em to Hell...

More than ready to do it, he took a long, slow, deep inhale through his nose, quietly catching the aroma of Jen's natural body odor.

Fuck yeah...she smells so damn good...and...she's so fucking hot...

His eyes were directed toward the TV, which neither of the otters were watching, and he exhaled, enjoying the feeling his sister's scent had stirred in his shorts.

Hell yeah. That was a good one. So good, in fact, that he began to inhale again. And this time, right when he started to smell her, Jen, who was still looking at her phone in one hand, reached down the front of her short shorts, relieved herself of an uncomfortability unbeknownst to her brother, and rested her hand on her stomach, closer to Zak than it was before. Close enough in fact that, in addition to her body odor courtesy of a soccer game in the hot sun, he also caught a good long whiff of the strong bouquet emanating from the increasingly irresistable temptation that was his sister's pussy.

His cock throbbed in his shorts harder than it ever had before in his life. The smell was so strong, he no longer needed to take deep breaths to capture it. And with each whiff, his cock throbbed more and more, and was begininning to ache as it did so. Meanwhile, in his head, his mind was racing from thought to thought, and Zak was imagining doing all kinds of things to his sister. He wanted to kiss her, to smell her, to taste her, to fuck her...

He kept having these thoughts until suddenly, there was movement. She raised her right leg out of her brother's lap and over his head to set it up on the top of the loveseat behind his neck and rested it there, her foot hanging off the edge of the sofa. Zak didn't move, his eyes on the TV, and a moment later, more movement. Jen moved her left leg out of her brother's lap as well and rested that foot on the floor. Zak kept waiting. Waiting until he felt safe to indulge in his silent incestuous desires. Out of his peripheral, he saw his sister bring her hand (the one that smelled of her intoxicating pussy) to her face, and thought that she was going to scratch her chin or between her ears, or even anywhere on her face. But he learned he was wrong when she brought her fingers to her nose and, unabashedly, inhaled deeply.

Ooohh man...I don't know what the fuck to do...she has to know what she's doing, she just has to...fuck...maybe she wants it as bad as I do...

His sister was teasing him, he was sure of that. The twins already had tons of things in common. Was it so inconceivable that she felt the same about him as he did about her? He looked in his sister's direction, and saw that her sportsbra had ridden up, probably from her trying to get comfy while lying back on the leather loveseat, and he could see the bases of the two perfectly symmetrical, perfectly round breasts of his own twin sister, covered by a thin tight layer of black nylon which shone under the overhead light in the room, emphasizing her still-hard tits that Zak so desperately wanted to touch.

And damn it if she didn't "adjust" herself again! Only this time, it wasn't her feet or her legs. Hell, she didn't even bother to pull her top down. No. Instead, she used the strength in both her legs and lifted her pelvis off the couch a little, consequently sending a delightfully strong breeze of her pussy smell right to her brother's nose, then actually pulled herself further down closer to him using the floor and the edge of the sofa as leverage, so that her vagina was pressed right up against his outer thigh. And if that wasn't enough, her top had ridden up even more as she had pulled herself across the leather, showing enough boobage that Zak could have cupped one in each hand if he'd had the guts to.

He had to engage. He had to do something that he knew would make them BOTH hot and bothered, because this party-of-one shit was giving him blueballs. But what could he do? How could he effectively get his sister ready to fuck?

He looked down at the TV remote in his hand, and an idea hatched in his brain. He looked at Jen, still on her phone, then back at the TV and pressed the On Demand button, bringing up the menu showing every program on every channel their service provider had to offer. Including...

...Yes!

There parents, like any other customer with children, were given the option to set parental blocks to any channel they should want to choose. This option, they declined. The way there mom and dad figured it, they had three children, all of whom spent more time outside playing than inside watching TV. And when the kids were inside, the two oldest ones were doing their homework or having practice sessions with their band in the basement, and the youngest only watched cartoons because those were the only channels that showed anything he had heard of, or even knew existed.

So, where there's a TV with no parental blocks, there's nothing to stop someone - anyone - from ordering an X-rated movie.

Within seconds, Zak had pulled up the very long list of every adult film available for purchase on demand. And after another quick glance at his oblivious sister, he began skimming.

He eagle-eyed the list calmly and quickly, looking for the perfect selection. Whatever movie he picked, whatever purchase he was about to make with Dad's credit card, whatever film he was going to sit and watch while his sister lay right next to him, he knew he had to pick one that was incestuous. He wanted to plant the seed in her brain, so to speak, to get her so wet that she would succumb to the ultimate taboo without a second thought.

Unfortunately, incest-based movies were not available for purchase. Which he knew, which is why he wasn't in fact looking for full-on incest movies, but rather, the next best thing.

"Ooohh yeah..." A different, darker kind of grin spread across the young male otter's muzzle as he pressed select on a movie entitled "Mom and Dad Aren't Home: Fucking My Hot Stepsister"

Jen looked at her brother, then followed his gaze to the TV, and became instantly curious. "What'd ya pick, bro?"

"Just wait, sis...It's something we both wanna see." He turned to his sister, smiling coyly, and leaned back against the leather cushion behind him.

Jen's curiousity magnified when she met his gaze, and turned into surprise when she saw the huge boner in her brother's shorts. She locked her wide gaze on his tent for a moment, then looked him in the eye again, and she saw something. A lusty desire burning in the center of his pupils. And for her, there was something about the look in his eyes that made her feel a certain small desire as well. She finally broke eye contact with her brother when he mouthed the word, "Watch,", and turned to face the TV.

The film started out introducing the two main stars, who just happened to be otters, as "new siblings", and in the scenario, they were arguing over who got the nicest bedroom. This went on for a moment until the sister said to the brother, "I'll fuck you for it," and before long, the two new siblings were engaging in semi-incestuous intercourse.

Zak leaned forward in his seat and watched intently, making no attempt to calm himself down in his pants, or even hide his hard-on from his sister. But it didn't matter because she wasn't looking at his bulge anyway. She was watching the movie, becoming more and more entranced not just by the foreplay in which the two otters were engaging, but by the idea the film implied. A brother and sister, having amazingly hot sex. With each other.

And as she thought more about it, she began getting wet herself. She looked at Zak, who was rubbing his bulge, no doubt while thinking about the concept of brother-sister sex himself, and sat up on the loveseat, leaning forward as well.

"Hey, bro?" she said, half-curious, half-sexually aroused. She kept her eyes on the TV.

"Yeah, sis?" Zak answered, his voice a little deeper than usual. Jen personally found his low tone kind of hot.

She asked him. "Have you...have you ever thought..."

A moment of silence, save for the movie in the background. Then...

"Ever thought what?" he asked. He didn't take his eyes off the movie, but he knew his sister was on the same train of thought he was. Come on, sis...say it....

"Well..." She had trouble gathering her thoughts as she watched the hot step-sibling otter sex with her brother. "Whoa...that looks like fun..."

Zak looked at his sister, smiling excitedly. He chuckled, then said, "What does? Gettin' your pussy licked?" The plan was working...

Jen nodded. "Fuck yeah! I bet I could cum just from that! I mean, if I ever met a guy who was good enough."

Zak chuckled. "Yeah, good luck with that! It takes true skill and prowess of the tongue to make a girl squirt, and it's already well known around school that I, Zak the Otter, am the best of the best!"

Jen smacked her lips. "Whatever, bro! I know for a fact you've never even seen a nice pair of titties!"

"That's not true," said Zak. "I've seen yours several times!"

Oh yes. He knew what he said, and by God he meant to say it. And the reaction from Jen was better than what he had expected.

Jen, his own sister, looked him in the eye for a moment, during which they exchanged devious grins.

"You like my tits?" Her smile was playful and mischievous, and altogether sexy.

Zak nodded, smiling back. "Fuck yeah, sis...matter of fact, I've kinda always wanted to touch'em." He didn't break eye contact. He wanted her to know he was serious.

Jen thought for a moment, then reached down in between her boobs and pulled out her $20, unfolded it, and slapped it on Zak's face, covering his eyes. And when he removed it, the first thing he saw was two of the most perfect breasts he had ever seen, right in his face. And the fact that they were his sister's made him that much more horny.

He was mesmerized by his sister's goods, lolling his tongue out like some kind of dog.

"You like?" asked Jen, bouncing them at little and watching her brother's eyes follow their every move.

"Fuck yeah, sis..." Zak wrapped his arms around her waist and pulled his sister closer, then began licking and sucking her tits.

Jen giggled. "Feels good, bro." Her tone was soft and full of lust, and it was then that she straddled her brother, pressing his bulge against her tight short shorts which were wet in the crotch area. As Zak licked and began massaging his sister's boobs, he also began grinding his bulge against her, eliciting a few small moans from her.

Zak was giving in more and more to his incest desires, and Jen could tell. She lifted his muzzle with her paw so that his eyes of blue were locked with hers of green, and responded to his deep hot breaths with her own, and then, slowly, she leaned down and he leaned up, they closed their eyes, and the otter siblings were engaging in a deep tongue kiss with each other, both discovering a new need, as well as a forbidden love for each other. They knew they were brother and sister, and they loved it.

Jen's lips felt so good against his own, and she was a damn good kisser herself. Feeling brave, Zak swiftly but smoothly slid his tongue into his sister's maw and moaned deeply into the kiss as he explored her mouth.

The female otter couldn't help but grind against her brother as she returned the favor and slid her tongue into his maw, the taste of which only made her more wet, filling both of there noses with the scent of sex and kicking their teenaged hormones into overdrive.

Zak slid his hands down to his sister's perfect perky ass and gave it a firm squeeze, making Jen gasp aloud, breaking the kiss. She looked down at him and saw the look in his eyes, not knowing what to think of it. Until, that is, he slowly eased her on her back on the leather couch, hooked his fingers in the elastic of her nylon shorts, and pulled them down, intensifying her strong feminine smell and revealing to himself his sister's beautiful perfect pussy. And when her shorts were completely off, she spread her legs (opening her hole for her brother) and began rubbing her pussy, getting it wetter and wetter for her hot otter bro.

Zak watched his sister play with herself, his own tip poking out of his shorts. "Damn, sis...you're makin' a puddle on the couch." He reached down and rubbed his fingers in his sister's pussyjuice, then brought it up to his nose and smelled it before opening his maw and tasting the sample. And the second Jen's sweet juice touched his tongue, Zak was hooked.

He murred deeply as he savored the taste, making Jen grin smugly and rub her pussy faster.

Zak smiled. "This is really fucking hot, isn't it..."

Jen let out a chuckle, looking up at her brother. "Hell yeah..."

"Here,", said Zak as he grabbed his sister's hand and moved it out of the way, stopping her rub session. Her lusty breathing calmed, but only for a moment.

Zak wasted no time in positioning his face inches away from her slit, which she was spreading open for her brother, and immediately began lapping and sucking on his sister's hot otter cunt, eating her out with a passion to be rivaled with.

It was only a moment before Jen lost control and wrapped her legs around her brother's head, enabling him to bury his muzzle deeper inside his sister and lick her in places that made her squirm more than anyone else ever had.

"Holy fuck...Oh my GOD yes..! Lick me, bro! Lick your sis!" She reached behind her to grab the arm of the couch and began face-fucking her brother, moaning and squealing as both his nose and his tongue rubbed and teased her clit, which in turn made her squirt a bit all in her brother's face.

Neither otter had ever been so horny in their lives as they had during this incestuous intercourse, and after Zak slurped up a good bit more of Jen's fluid, he pulled his head up, wiped his mouth with his forearm, stood up on the couch and said to her, "You're turn, dude."

Jen chuckled as she sat up, her knees digging into the leather, and began rubbing her brother's bulge through his shorts. "Hehe," she said as her brother moaned and humped against her webbed paw, "I gotta say bro...you got a big dick." She smiled up at him, and he smiled back. "Thanks, sis..."

She rubbed a little faster, making Zak's breathing pick up, and his tip rise out more and more, pre leaking from the tip. And when she'd finally waited long enough, she quickly pulled her brother's shorts down, and his nine-inch otter rod fell like a tree onto her muzzle.

Zak had definitely gotten a little relief at his newfound freedom, but only got more turned on at the sight of his sister's smiling face rubbing and nuzzling his dick. Her fur was so soft that he couldn't help but slap her cheeks with it. He slapped her with it even more when she stuck her tongue out, and moaned everytime his dick slid across it the right way.

Jen grinned up at her brother. "You like my tongue, bro?"

Zak, panting a little, nodded at her. "I love everything about you, sis..."

And after a brief moment, Jen grabbed her brother's long otter cock and gave it a deep, hard suck, making Zak's legs wobble as he threw his head back and moaned loudly. No one who had ever sucked his dick made him feel as good as his sister was at that moment.

Apparently, when it came to giving head, Jen was no amateur. It wasn't long before she was taking in his full length without a problem. Her head was going back and forth with ease, and Zak was loving every bit of it. In fact, it wasn't long before he grabbed her head and began muzzle-fucking her himself. It felt amazing, shoving his cock in and out of his sister's mouth, but after one last thrust, he had to stop himself or he would've cum down her throat. No...if he was going to cum in his sister, he was going to do it the way he'd been wanting to since he first had a wet dream about her.

The siblings were both breathing quickly and their hearts were pounding courtesy of the dark lust they held for each other. And when they looked into each other's eyes yet again, they both knew what the other one wanted.

"...Jen?..."

"...Yeah, Zak?..."

He looked down at his sister, then sat down on the couch with her, leaning back with his cock standing straight up. "No matter what..."

Jen listened, waiting to hear him out.

Zak took a deep breath and swallowed. "Mom and Dad can never know..."

Jen nodded in agreement before pinning her brother back on the couch, surprising him, and started grinding on his cock with her wet, dripping pussy. As Zak lay back and enjoyed not only the sensation on his dick, but the sight of his sister bouncing on top of him, he tried to resist just ramming it up inside her like he so desperately wanted.

But, thankfully, it wasn't long before his sister grabbed his cock and aimed it up directly at her pussy, and slowly began lowering herself onto it. And as the penetration was nearing completion, Zak learned just how tight his sister was, and Jen realized just how big her brother was.

The siblings moaned in equally lusty tones for each other as the fucking picked up the pace. It wasn't long before Jen was riding her brother like a bull, bouncing as hard and fast as she could on his big otter cock. And Zak couldn't help but grab her ass and give his sister the extra thrust that they both so badly needed. He watched and listened as his sister moaned and bounced on him, his eyes on her perfect perky tits, bouncing above him driving him crazy.

They both moaned louder and louder as they fucked, and when Zak reached up to get a squeeze of his sister's titties, the sensation made her release a high squeal and her pussy clenched tightly around her brother's cock, causing Zak to thrust upward inside his sister one last time as deep as he could before he finally shot load after load after load of hot otter cum inside his own sister. The orgasm was so good and lasted so long that neither of them cared about impregnation. They were just a young otter brother and sister who had the hottest sex ever with each other, and they loved it.

"Fuuuck yeah sis..." said Zak, his eyes closed, his heart pounding, and cum leaking out of his sister's pussy and dripping down his cock.

Jen leaned forward and lay on top of her brother, neither of them in a hurry to seperate from each other.

The siblings were awake, but had their eyes closed, breathing deeply, taking in the smell of their sex they had left lingering in the room.
