#1 of Incest Stories (Josh & Rose)

The first furry related smut story I ever wrote! It's been seven long years now, and I feel like I've come a long way as a writer, but that this story still holds up pretty well.

This short and sweet story tells the tale of Joshiah, a young, working class man still living with his folks and his sister, and the heat of said female complicating the peace of their humble home. When two young adults are sexually charged and both looking for someone to trust, they may find the person they needed all along is waiting for them right at home.

As always, read, comment and enjoy!


It was the end of another long, boring day at work. Joshiah opened the door to his household, not bothering to call out and see if anyone was home; he already knew that no one was. Despite living in a house with three other people, he felt like he lived alone already. His mother worked the opposite shift from him, his father was always out traveling for his business, and his sister, the only person who was ever around, always seemed to be out with friends, or too absorbed into an on-line game to even notice someone coming in the door.

"Least I get a little peace and quiet away from that dusty hellhole," Joshiah grumbled. His job wasn't the most glamorous one out there, as anyone who worked in a warehouse would attest. The air was dry and carried a scent of dust and rotten cardboard, something that became nearly intolerable to a canine with such a good sense of smell. Thankfully, different, more enjoyable scents awaited the wolfox at home.

"Thank God there's actually something to eat around here for once," he said to himself, as he opened the fridge and spied a couple of take-out boxes. Leftover Chinese wasn't the greatest thing in the world, but the scent coming off of it was plenty enough to keep him interested, and in the end, his stomach won the battle. He hastily removed the boxes and emptied the contents onto a dish, popping them in the microwave and waiting as his tummy rumbled in anticipation.

He became so enamored with his soon-to-be dinner that he almost didn't pick up on another scent. "Hmm...wonder what that is?" he asked, as his muzzle wrinkled a tiny bit. It was definitely a feminine scent, and one that he'd picked up before, but he was hardly in a mood to care.

Up the stairs in his living room, to the hallway where his bedroom and his sister's bedroom was, also contained the source of the scent. Joshiah hadn't given his sister enough credit about noticing the presence of people entering the house. Right now, Rose was more than aware of it, and even cautious of it. A silly on-line game couldn't begin to hold her attention...

...Not when her pawtips were dipping deep into her panties, two of the gently furred digits stroking ever so slightly at her labia. "I know he's home...but I just can't stop myself...it's never been this bad before!" she tried to whisper to herself, on the off chance that her brother might hear. He'd always been a rather sensory being, and she always worried that he knew what she really did while everyone was away.

The light blue of her panties was stained with arousal, leaving them a darker color around her slit, in contrast to her soft, bright tan fur. She took more after her mother, resembling more of a fennec fox, while her brother took almost directly after their father, a pure, natural wolf. She'd always admired his appearance and strength a little bit, but she could never dream of anything incestuous with him. Even innocent wrestling matches and tickle fights between the two, which they were frequently in, were starting to weigh on her mind now.

She was in heat; there was no denying that. Still, she'd never experienced quite a feeling as this. When she was younger, sexuality didn't appeal to her so much, but she was an adult now, 22 years of age, and her brother was 21. She'd been saving herself for the right moment, having had plenty of chances, but knowing that none of them had been right. "I can trust him, though, right...? I mean, he is my brother...I've always been able to trust him, he's always helped me when I needed it," she explained, as if arguing with her thoughts.

A distant '_ DING _!' made her ears flicker. Joshiah, still down in the kitchen, took his plate from the microwave and grabbed a fork, then closed the door to both appliances with his tail. Without even waiting for his rangoons and white rice to cool, he started digging in, all the while, walking towards the living room, and then turning up the stairs.

Joshiah stopped when he got to the top of the stairs. What greeted him was a scent of pure, unbridled arousal. Remembering that he was mid-chew with a mouthful of food, he swallowed what felt like a lump, and simply stood for a moment. He knew this scent for certain, now. It was the last time his sister was in heat, and the first time he'd been around for it, the year before. The memories exploded at him as if it were just yesterday, as he quickly hustled past her room, not caring to look at her closed door, or stop to try and open it.

Nearly running into his room and closing the door, Joshiah inhaled the rest of his food, and sat on his bed, tail wagging about rapidly, a combination of nervous excitement, and dreadful concern. "I had to hide from her for almost a week...anytime I got near her, I just wanted to shred her clothes and pin her down! That scent is just too much...I know she can't help it, and I know she doesn't mean to, but she's already driving me crazy!"

Joshiah was no stranger to the pent-up lifestyle. He'd been in more close encounters with the opposite sex than almost anyone he knew, but there was no question to his morale. The girls were always drunk, emotionally unstable, or just in it for the sex. None of those options appealed to him, and so, even after 21 years, he still hadn't had a female to his own. The pink tip of his member started to poke past his sheath, as it had done so many times in the past. This time, he was tired of waiting. She was obviously wanting, and he couldn't resist such a powerful scent.

"I can trust my sister, right? I've always been able to tell her anything..."

Making sure to keep his clothes on, and his arousal as hidden as possible, Joshiah opened the door to his room. He knew that the two of them would have all the privacy they could ever need, and that it would stay a secret, if it happened. His nerves continued to get the better of him, however, and he had only made it halfway down the hall in slow, quiet steps, when the door to Rose's room cracked open.

"Josh...could you come here for a minute?" she asked, in a calm, comforting voice. The arousal that escaped when her door opened was even stronger, but Rose seemed so quiet and casual that Joshiah was taken aback.

"I...y-yeah, sure." he rambled off, looking aside with a faint blush. He felt silly, being unable to speak properly, but he tried to shrug it off, stepping over to the door as Rose disappeared back inside. He took a deep breath, tried to relax, and open the door, and as he walked in, his chest dropped a little bit.

There was Rose, standing in her usual blue jeans and a red tank-top. Her paws were behind her back, though, and she did look adorably shy.

Feeling somewhat relieved, Joshiah sighed quietly and closed the door behind him, as if he had any reason to. "What's up?" he asked, as casually as could be.

Rose just stood there for a moment, as, when Joshiah entered the room, his own scent of arousal had mingled with her own, sending a chill down her spine. She'd tried to be reserved, and calm in her approach, but as the undeniably male scent of her brother filled her muzzle, she gave in.

"Please...help me..." she nearly whimpered, slowly closing the gap between them. Joshiah almost felt a knee-jerk reaction to move, but his legs felt like they were trapped in cement. He stayed put, as Rose put her paws on his shoulders and looked him right in the eyes. "I'm sorry to have to ask this of you, but I don't know where else to turn, Josh. I...I need a male, to mate with me, and I can't think of anyone I trust more than you. I don't think I can trust anyone but you..."

Joshiah knew his sister had concerns with trusting males in the past, but her words spoke volumes beyond what his suspicions were. Gulping as quietly as he could, he tried to deny that his stiff tip was starting to push up and over the hem of his loose fitting jeans. "But, Rose...it's not right. We're related!" he tried to exclaim, though he felt little faith in his argument at this point.

Rose, always keen in the eyes, let her gaze drift down, over the chest fluff of her brother, down his uncovered, toned stomach, and to the stiff, growing cock that started to push past his jeans. "Don't be so shy, brother. I can tell how much it drives you crazy to have to deal with my scent like this. You can trust me, and I feel I can only trust you...we love each other. You may think it's not 'right', but I can't see how it's wrong." she tried to argue, as one of her paws trailed down his body, to take the tip of his length in her pawtips, still damp from teasing at her petals earlier.

"I..." Joshiah tried to speak, but as his sister took his length in her paw, his inhibitions started to melt. There was no denying it anymore. The dominant, alpha wolf that rested deep within an otherwise calm, reserved person started to come forth, just enough for Joshiah to break from his sister's grasp. "Let me get a condom, at least."

Rose's eyes lit up a little bit as her younger brother finally started to give in to the idea. Leaning in and biting fiercely at his neck, she left him with a light mark in his fur, before giving him a playful shove. "You've got fifteen seconds." she said, rushing him out the door.

Joshiah fell into the hallway and practically ran to his room, his mind racing as he tried to make sense of what was going on. It was obvious that he and his sister had a history of sexual tension, but he'd never dreamed of it coming to fruition like this. Frantically, he slipped back into his room, and headed over to his dressed, frantically ripping open the top drawer and fishing out a box of condoms. He took one out, and before he could even rip open the packaging, a flash of fur pinned him down to his floor.

There, sitting on his lap, was a now naked vixen-wolf, showing off just how much of an alpha she really was. Between the two, Rose had always been the more dominant one, but she had to be in just the right mood. Lucky for Josh, she was in it right now, and he could feel it, as the damp, heated depths of her body rested right over his covered length, drawing a deep gasp from him.

" Ahhn! Ooh...Rose, what...-

"I got tired of waiting." she cut him off, licking her muzzle hungrily as her claws gripped at his jeans, actually yanking the button clean off of the fabric as she ripped them, and started to tug down. As if knowing his role now, Joshiah lifted his legs just enough for Rose to get the pesky material out of the way. His silken boxers didn't stand a chance, as they too met with a vixen's claws, and were left in tatters. Joshiah could only watch with wide eyes and a breathless expression as his fully engorged cock now stood before his sister. "Gimme. Now." she demanded, wrapping a paw tightly around the base of his cock, before she leaned down, running the flat of her tongue along the whole length, leaving it glistening with her saliva.

"Ooooh...God that's good!" Joshiah suddenly moaned. Though he wouldn't admit it, he'd never so much as gotten touched there by a female, and the sensation of having his sister lick his flesh was almost more than he could bear. His back actually arched against the floor, pushing the head against his Rose's cheek, making her giggle.

"Someone's really enjoying this, hmmm?" she asked, her voice almost tauntingly sing-songish. Knowing her brother couldn't escape her now, she felt a fresh rush of excitement in taking control of the situation, as she started to lightly stroke her paw up and down over his length, while her tongue coiled around the head, slurping back and forth over it.

Joshiah went silent as he tried to moan, but his voice couldn't match the pleasure that he felt. Instead, a silent whimper was all he could make, as his claws dug into the carpeted floor beneath him. "You have no idea!" he called out breathlessly, as a few spritzes of pre-cum soaked the tip of his sister's tongue.

She swallowed them eagerly, slowly retracting her tongue from his cock. "I'm about to find out." she assured him, looking over his now soaked length with approval, and actually wincing as the sight reminded her of how badly she needed to be filled. Reaching up and pressing her claws firmly into her brother's stomach, Rose climbed back up into his lap and positioned her naked slit right over the head of his member.

"Be a good boy, sit back, and enjoy it...and let me take what I want." Rose demanded, letting her instincts take full control now. She had already started to descend her body onto his length, and Joshiah, already too absorbed at the sight of her dripping wet, tight folds of flesh, completely forgot about the condom. He could only nod in silent awe as her lips started to expand around the tip, and slowly take the first two inches.

"Are you sure...that you're ready?" Joshiah asked breathlessly, starting to feel some resistance within her.

"It's just my first time, and you're, well...you're really big." Rose mentioned, blushing for the first time since she'd pounced her brother down. "But I think you can feel how ready I am..." she finished in a low, lustful voice, as she started to push down a little further on his length.

Joshiah knew she was right. It was a feeling unlike anything he'd ever known before, and nothing could prepare him for it. It was warm; almost hot, but just right for his cock, and the walls were so tight and slick, nothing else would ever compare. His length throbbed inside of her, causing her to buck gently, and finally, hilt herself with his member, as the slit of her femininity pressed against his crotch with a wet, sticky sound.

"I'm sorry...if I...don't last long," Joshiah tried to say between gasps. Rose simply chuckled a little bit, though she was moaning plenty herself. "That's just what I want, little brother. A quick fuck and a bathing of cum to satiate this heat..." she assured him, as she started to lean her upper half over. Her full, soft breasts pressed up against his chest as she dug her claws into his sides, deep enough to leave a mark. "Now fuck me."

Joshiah took well to the submissive role, as he reached up and dug his claws into his sister's back, providing him a suitable grip as his hips pushed upwards, causing Rose to gently bounce against his length, as brother and sister gave each other their virginity. As shy as he was about it all, Joshiah could no longer hold his own voice, and Rose couldn't contain herself, as she pushed her hips back down onto his length.

"Rose...you feel amazing! Oooh...it's so tight!" Joshiah called out, his hips starting to move on their own as he thrusted his cock deep into his sister's wet flesh, trying to keep in time with her hips as she pushed back against him. It was okay; they were both inexperienced, and in this moment of heated pleasure, neither one of them had to be perfect. They were already meant for each other, even if it was just for this one romp.

"You're so big! Josh! Please don't stop!" Rose called out, as the desperation of her heat only seemed to intensify with each thrust. She knew for certain now that the only way she would feel satisfied was by orgasm, and thankfully, her heat made that much easier than before. They were true to their canine nature, in that a hard, rough, and fast session was all they really needed, right now.

Joshiah's moans faded into deep, lusty growls, as his own instincts started to take hold. It almost got him to the point of flipping her over and taking her in a mounted position, but his sister was the alpha right now, and he had no problem with her being in control. He simply aimed to please, as he gripped tighter at her back, leaving deep claw marks in her fur and even her flesh, as his thrusts intensified, his orgasm drawing closer as spurts of hot pre-cum started to fill her passage.

"Hehe...such an animal, little brother. Maybe next time, I'll let you get on top! Oooh!" Rose teased, though her voice couldn't tease forever as it gave back in to joining the chorus of pleasure that they'd started. Her inner muscles started to clamp down on the stiff, full cock that was pumping deep inside of her loins, trying to milk it for every drop of that delightful pre-cum, and hopefully, something more afterwards.

The words echoed in Joshiah's head. 'Next time?' he thought to himself, already in disbelief that this was happening once. He couldn't imagine his sister wanting to do this again, but she was already planning it, and as the notion settled in his mind, he found it a bit comforting that his sister trusted him so much. The train of thought was quickly derailed, as he felt his orgasm building.

"Rose...I need to...I'm gonna...!" he tried to warn her, but his words only seemed to encourage his sister, who could feel her own warm, tingling release building in her body. Her claws moved rigidly up his sides, leaving deep marks in his flesh as she grasped at his chest fluff. "Don't you dare stop..." she growled dominantly, nearly bearing her fangs as her hips bucked violently at his cock, her thrusts becoming more and more erratic.

Joshiah gritted his teeth as he tried to hold out, unable to deny how amazing his sister felt, and unable to deny his cock from bursting. His knot started pushing forth as he tried to last just one moment longer, but he felt something incredible, as his sister's walls started to flutter on the tip of his length.

"Josh!! I'm cumming! Fuck!" she called out, gripping even tighter at his chest as she threw her whole body at his, completely dominated by the pleasure that tore through every fiber of her being. She gave into it, nearly howling as she had to bite down on her brother's shoulder for fear her screams might alert the neighbors.

Having just barely made it as long as he needed, Joshiah unclenched his fangs and let out a completely exasperated breath, as he pushed up on his sister's body, just enough to free his cock from her dripping slit. "Rose!! I'm...cum...ming...ahnn!" Joshiah managed to gasp out, and then finish his praise of his sister as his cock erupted, his knot throbbing in open space as strands of long, sticky cum burst into the air, the mess shooting all over his sister's chest and tummy, and even some on his own body, as, just as she'd asked, he literally bathed her in it, even if the mess made it's way to him.

For a moment, his cock simply throbbed against his sister's clit, extending her orgasm just a little bit longer as the two tried to catch their breath, while more and more of the white, sticky seed covered their fur. "Mnnn...shame I couldn't just cum inside you, it'd be a lot less messy." Joshiah pointed out, snickering up at his exhausted sister.

Rose stuck her tongue out at him, reaching down a wiping a pawtip in the mess, and dabbing it on his nose, making Joshiah wrinkle his muzzle. "Punk...but thank you for pulling out. I completely lost control there...there's no way I would've let you out if I didn't have to." Rose admitted, blushing warmly once again, adding to the beauty of her image. Joshiah wouldn't deny that he liked the look of his sister completely naked, and covered in his mess. The blush was just the other icing on the cake, so to speak.

"Thank you for trusting me with this," Joshiah said plainly, though his smile was genuine. It meant a lot to him that his sister would come to him for aid, even if it was something as taboo as this. "And don't be afraid to do it again if you need to."

"I plan on it," Rose assured her spent brother, leaning in and licking the bit of mess off the tip of his nose, before smiling at him affectionately. "Mom will probably be home in a couple hours. I'm gonna go get cleaned up and try to air the scent out of the place, okay...?"

Joshiah nodded with a rather shy smile. Their mingled scents and mixed juices did leave a rather amorous scent to the place, and he was sure that it would reach the living room if they let it go. "Alright. Mind if I join you in the shower?" he asked, still smiling, and even a bit more warmly now.

"Hmmm. Sure, why not? We used to shower together as kids, right? I'm sure it'll be just the same as it used to be," Rose said, smiling back down at her brother and giving him an unexpected peck on the lips. Joshiah blinked, his eyes going wide as he blushed at the uncharacteristic show of affection, his cheeks brighter than they had been from any of their other acts.

Rose stood up, still dripping in her brother's mess, and helped her brother up to his footpaws. Taking one of his paws, she lead him down the hallway to the shower, having more than a few ideas for what they could do in the sizable bathroom...
