#3 of Incest Stories (Josh & Rose)

The finale of the incest trilogy, written a few odd years ago! This one came about a year after the first two, however, and I feel my skills had improved greatly by the time, making this my personal favorite chapter.

In the finale, Joshiah and Rose have an established and consistent incestuous relationship, exploring a world of different kinks and styles together, all while keeping the relationship a secret from everyone. What starts as a little punishment for being rude quickly balloons into full on pegging, but when Rose is overcome by her lust, she makes a decision that could put their secret in jeopardy, and truly puts her brother's love for her to the ultimate test.

As always, read, comment and enjoy!


The hustle and bustle of the outside world peacefully gave way to the calm and serenity of home as Joshiah stepped in the door from another day of work. As usual, no one would have been home but his sister, and as usual, there wasn't a peep from her as he entered.

Life had gotten mighty interesting for the young wolfox over the past year. In that time, he'd decided to get back into college and finish his degree, tried to look for a new job that could actually blossom into a career, and finished writing his first full length novel.

He'd also, more excitingly, started fucking his sister on at least a weekly basis.

The memory of their first sexual encounter was still fresh in his mind. He'd gotten home from work on a day just like this one, right in the middle of her heat cycle, and from there, nature simply took over. Their baser instincts overtook their better minds, and before they knew it, they were practically addicted to each other. At least once a week after work,

Joshiah would enter their house, only to find Rose in the hallway, wearing nothing but the fur that God gave her, simply begging for a thick, hard cock to fill her.

Joshiah dropped his supply bag from work on the floor and shrugged off his shirt, trying to stay cool in the sweltering summer heat, as he mentally prepared to embark on another afternoon of hammering himself into his sister's loins.

"Rose! I'm home!"

There was no response.

Wondering if perhaps she was playing coy, Joshiah started up the stairway to the second story of the house, nearly jogging up the stairs in his bottled up excitement, but when he got to the top, all he saw was an empty hallway.

"Rose?"

Again, his call heeded no answer.

Normally, the wolfox wouldn't have been so aggressive in his search for his sibling, but the summer heat did something to him that was similar to the physical heat that his sister underwent. Every day at work, he could feel his groin stirring, and his cock just begging to be released from it's sheath so that he could take care of business.

His impatience guided him down the hallway, right to Rose's room. The door was all the way closed, which struck Joshiah as odd, as she often left her door at least a little bit open. "Hello?" he asked, as he forewent knocking on the door, and simply opened it and stepped inside.

Rose was standing there, nude, as Joshiah had expected, but she was facing away from the door, and her tail was firmly draped down over her supple, shapely rump, keeping her appearance at least a little modest. Her paws were behind her back, gently clasped together, leaving an air of dignity about her.

"So rude...you didn't even knock. I thought I'd trained my little brother better!" she suddenly spoke, her voice sharp, and even slightly offended, as she started to turn, casting an angered eye in her brother's direction. "I was hoping I could treat this more like a reward, but I guess I still have to teach you a lesson..." she finished, her stern, scolding appearance starting to fade into a teasing smile.

Joshiah let out a nearly gasping sigh of relief as his sister's facial expression softened, his heart rate spiking as high as he'd ever felt it, just before easing back down. Rose still wasn't turned all the way around, and the curiosity that had been literally scared out of him a moment before started to creep back into his mind. "Well, I am sorry, Mistress, but you didn't answer when I came home...hopefully I'm not in too much trouble?"

Moving elegantly, turning just slightly on one paw, Rose changed her pose to a side profile, and from just past her thigh, a long, blue shaft stuck out. Joshiah's jaw started to drop slightly as Rose completed her turn, standing face to face with her younger brother now, her face the picture of delight, and his, the picture of worried surprise.

"Oh yeah. You're in big, big trouble, my pet," she confirmed, setting her paws on her hips and pushing them forward just a little bit to show the heft that her toy held. "Turnabout is fair play, after all, and I've been dying to play with your tailhole, ever since I told you to fill mine with that hot, thick cum of yours...now, I've got my chance, and a very, very good reason."

Joshiah felt his tail slink down against his legs as he froze in place. His instincts told him to bolt for the door and forget that he'd ever knocked. Something about the moment was erotic, no doubt about it, but he wasn't sure that he was ready for something like this, if he would even be into it. "I...uh...Mistress? Is there any way I can beg my way out of this?" he asked, already letting a pleading tone into his voice.

Rose shook her head firmly, eyes closing as she went through the gesture, then opening again, her perfect emeralds looking positively deceptive in the sweet, innocent appeal they gave off. "I'm afraid not, little brother. In fact, if you try and protest, I'll tie you up, and then take your tailhole, so...the choice is yours."

A twisted feeling of fear and excitement crept through the young wolfox, making the tip of his tail lift ever so slightly. Deep inside, he couldn't resist the thrill of being tied up and taken, but he still wasn't sure if he would be so into the idea of having something in his back door.

"Although, I think you've already made your choice...and I like it," Rose said, her voice soft and drifting, almost like a long, drawn out sigh, filled with emotions. Joshiah had become so absorbed in his mental conundrum that he almost missed Rose slipping down, elegantly, to her knees, and resting by his crotch. She took in a light breath and started losing herself in the familiar scent of her favorite and only male, and the bulge that was pressing against the jeans that kept her from her true desire. "Already getting stiff, my pet? I'd say I'm ashamed that you don't have more control, but...that would be a lie.

Oooh...damnit! Joshiah thought to himself, having been completely betrayed by his body. The thought of being bound by his vixen-wolfess sister was just a bit too much for his body to handle, and it caved in. Under the front of his jeans, the tip of his warm, pink member was already starting to peak past his fuzzy sheath. "I suppose I don't have much of a choice in this, do I...?"

The sound of jeans unzipping, and the feeling of cool air rushing into his heated flesh was the best response that Joshiah could have asked for. "Of course not, lover, but it is cute that you would ask," Rose teased, greedily wrapping her lips around the tip of his cock as soon as it was exposed to her maw.

Unsteady paws gripped upon a wooden bedpost, Joshiah's claws pressing into the woodwork as Rose's maw sent shocks of pleasure through his whole body. His cock almost immediately grew in her maw, making her eyes widen with surprise, and her lips curl into a devious smile. Knowing that her brother was off balance, Rose effortlessly pushed him down into her bed and stood up, looking down over her soon-to-be captive. "I'm not sure you can be trusted to cooperate through this, so...I'll just tie you down anyway. Something tells me you'll like it!"

Joshiah knew better than to protest any further, for his own good. He thought about trying to hop off of the bed, but before he could finish the idea, a rope cuff found it's way around his right ankle and tightened up, keeping him from straying. "What the...where did you get that?!" the wolfox yelled, completely stunned that she was able to get something on him so quickly.

A second rope cuff was quickly fastened around his left ankle, keeping the wolfox stuck to the bed. "It came with the other toy I'm going to use on you," Rose explained, gesturing down at the fake member that was nestled into her nethers. "You simply slip it under your mattress, but above the frame...it's easy to keep hidden, and just as easy to break out in a hurry, to keep you from getting any ideas."

"You never cease to amaze me, sis. Perhaps I should be a little more open minded...I know you'd never do anything that mean to me, right?" Joshiah asked, relinquishing himself to the fact that he could no longer move from the bed.

"Hmmm...I don't know, little brother. You are my fuck toy, after all," Rose mused, but it was all too clear that she was teasing, just in the way that she grinned at her tied up sibling. "Now then...shall we get you ready?" she asked, leaning down into his legs and spreading them open a bit. She moved up onto his body, the fake, cold member pushing up against

Joshiah's warm, fully erect cock. A quiet, slightly shameful moan escaped the young wolfox's lips, but they were quickly sealed over as Rose leaned in and took an intimate taste of him. As their lips gently pressed and moved against each other, the clever, crafty vixen wolfess managed to slip the top two cuffs around Joshiah's wrists, not feeling any resistance from him as she completed the act.

A shared chorus of light gasps broke the air as Rose slowly released her younger brother's lips. Satisfaction played about her so much that she almost looked cheeky. "Just relax, my pet," she started, resting a paw daintily upon his chestfluff, kneading her pawtips through it as her other paw picked up a conveniently nearby bottle of lube. "If you give it a chance, I promise that you'll enjoy it."

Joshiah was slowly warming up to the idea, perhaps even finding himself eager to try it as his dominant sister was already working on the next step. He watched as his jeans were casually tossed aside, with his boxers quickly following. He couldn't help tensing up a little bit as his sister leaned back forward, closing her sharp, shiny fangs over one of his nipples, and suckled tightly upon it, just to tease his body a step further. "You know I'd do anything for you, ahhh...Mistress..." he said breathlessly, just trying to keep enough composure to respond properly. "Ahh! Hey! What...what are you doing down there?"

Rose grinned toothily as her thumb, slicked with lube, started gently rubbing around the opening to her wolfox's tailhole. "I'm getting you warmed up! What do you think this is, some kind of a silly porno? You can't just shove a cock in your tailhole without warming up first..." Rose explained bluntly, letting the pad of her thumb press right up against the tight pucker, before it slipped in with a nearly inaudible _ pop _!

The now overly anxious wolfox clenched his fangs tight together, expecting some kind of pain, and Rose could tell, as her thumb was literally clenched in place, but no pain ever came. There was a slight pressure, but it was nothing too uncomfortable. Instead, Joshiah found himself quickly enjoying the feeling, and as his tailhole loosened a little bit, Rose urged further onward, burying her thumb inside her brother, right to her palm. "That...that isn't so bad," Joshiah mused in surprise, feeling the calm, relaxed air wash over him, allowing him to relinquish his body to the pleasure that awaited it.

"Told ya," Rose bragged, her grin as strong as ever. Her pawtips, still free to roam, started gently caressing over her brother's lightly furred sack, making his cock jump about as pleasure shot through it, right up to the tip in the form of glistening precum. The juices started to trickle down his length painfully slowly, messing against the fake member that was still pressed upon him. In all ways, Rose was in control, and keeping him pinned. "In fact, I'd say you're loving this already..."

Before Joshiah could hope to protest, Rose was pushing him even further still. As her thumb wriggled about inside his tailhole, helping to relax and loosen him up, her body was doing its own work. Her smooth, curvaceous figure was pressed tightly up against to her constricted brother. Large, supple breasts rested upon her brother's flat, toned chest, right in his face, and yet, right out of his reach. Joshiah nearly whimpered at the sight, wishing that he could so much as draw a pawtip down the side of one of her soft, perfect tits, but he was completely bound, only able to let his tongue slip past his maw, dripping with saliva in anticipation at the chance to taste her.

"You know I'd love for you to suck my breasts, brother, but if you're really that eager, you're gonna have to beg ," Rose said, acting as though she could read her lovers thoughts, and capitalizing on them as soon as they came into his mind. Rose had turned teasing into an art, and she enjoyed it so that she seemed to gain some kind of sexual gratification from it.

Though the false member nestled in her nethers had no nerve endings, the vibrating bullet inserted in the base kept her swimming in pleasure as she teased, something that her brother very quickly came to appreciate.

"Please, let me taste you, my sister...I'm so desperately thirsty for you..." Joshiah whimpered, taking perfectly to the role of the pleasuring slave that his sister had forced him into. Tiny trails of saliva drizzled over his tongue, simply dripping at the thought of sucking upon her perky, tasty nipples, and his precum flowed freely to tell the same.

Rose pressed the pad of her thumb up in a harsh, domineering thrust, pinning her paw inside of her brother's backdoor. "That's Mistress Sister to you, brother...perhaps you aren't thirsty enough to enjoy a drink from these soft, sweet breasts," she suggested, drawing her teasing paw away from the base of her brother's fuzzed sack and sliding it up along her tummy, making a show of the slow, captivating movement, just as the paw came to rest under her right breast. Giving her brother a look that could make a Popsicle melt, she pushed her breast up towards her own muzzle, and with a wink, she sealed her lips over her own nipple, moving her tongue expertly around the stiffened peak...

And her brother could only sit and enjoy the show, struggling against his bindings as his cock throbbed and jumped against the vixen's fake length. Keeping even his member pinned down gave Rose a new level of dominance over her brother that she'd never known before, and it was clear by the near streams of her arousal running down her thighs that this was a kink she'd happily explore again, though she wasn't nearly done with this opportunity.

"Mm...Mistress Sister...let me taste your breasts, please...let me pleasure you while you use me to your fullest desires," Joshiah rumbled out pathetically once again, so desperately aroused by the show in front of him that he wasn't afraid to plead for a taste of his sister's flesh. Though fires of lust burned through the very core of his being, he was content to play the part of a helpless slave...as long as his sister eventually gave him what he wanted.

"Mmmnn! I dunno..." Rose pondered as she pulled her maw away from her breast with a pleasant _ pop _,a small splatter of saliva falling down from her breast to her brothers tummy. "I seem to be pretty good at this after all...perhaps I should just make you sit back and watch me tease myself until I cum...without ever giving you a chance to do so."That was finally a push too far for her eager, passion-ridden brother. "I don't think so...I'm not gonna sit back and let you cum without me, sis...lemme go, or else you're gonna pay for it."The threat did nothing to deter Rose, who pulled her thumb out of her brother's tailhole with another quiet _ pop _. She smoothed the pad of her thumb over the well-prepared orifice and grinned down at her brother with malicious intent, sliding the long, blue shaft of her fake member away from his real one and dragging the tip over his sack, she put it right in line with his backside. "Someone forgot to call me Mistress yet again...I'm afraid it's time I taught my silly little brother a lesson."

"And someone clearly didn't hear me...I said lemme gooooooooo!! Fuck!!" Joshiahs claws gripped at his bindings as the head and half of the shaft of his sister's toy easily slid inside his rear entrance with a wet _ schlick , falling prey to a fate he felt he should have known was coming, but that didn't make it any easier to take. The extra pressure had precum flowing down his cock and onto his crotch and tummy like a river, staining his fur with an endless desire for his incestuous partner. "You're..._ahhn...an evil bitch sometimes, Rose..."

"And don't you forget it...I have to get my fun in with you while I still can, brother dearest...and ever since you came in my ass in the shower, all that time ago...all I've wanted to do is plug your tailhole up the same way you did to me...so you better just lay back and enjoy this, because you're not going anywhere til I've had my fill," she confirmed, moving her hips forward and filling her brother to the hilt with her fake cock, the toy taking her brothers anal virginity with deceptive ease.

Joshiah could hardly remember all of the times that they'd made love between that shower and now. There were plenty of other steamy interludes in the shower, of course...and the time that they had sex in the pool in the back yard, and in the bushes at the park, and the absolutely feral fuckfest that had become their last spring break...it was impossible for him to count them all, but this was by far the kinkiest his sister had ever been, and suddenly, he found his gender being slightly less important than the mere fact that his sister had a sexual need that only he could fulfill.

"Just...nnngh...damn, that's a lot... try not to take too long. Brother needs his fill too, y'know," the spunky wolfox was quick to remind. With his strapping body pinned down against itself, he was in no position to make demands, but the constant throbbing and pulsing of his glistening cock made it clear that he would try anyway.

"Oh, don't worry...just be a good boy, and you'll get yours, my darling little brother...all of that tasty cum has to go somewhere, after all!" Rose pointed out with a playful grin, the delight on her lips derived from her sudden dominatrix role, and the vibrator nestled into the egg of her feeldoe, constantly making its presence known to her in the form of a quiet, yet powerful buzz, leaving her a few clit strokes from a powerful orgasm of her own. "And I don't plan on wasting a drop!"

The wolfox could hear the pleasured moans, lacing his sister's voice with pure lust as the words traveled over his sensitive ears like a silken cloth. "Tasty, huh?" he asked, as he started slowly working his rump back against the invading toy. Though he was completely inexperienced, he was quickly getting the feel for being on the receiving end, and his sister was taking him slowly enough. "Does that mean I get one of my sister's famous blowjobs for being good...?"

Rose stuck the pink tip of her tongue out and shook her head, letting her tongue slip out just long enough for a single drip of saliva to dangle down and then fall onto the tip of her bound brother's length. "Nu uh..." she said playfully, letting the bead of saliva break away from her. "I have other plans for your cum tonight, my dear brother..."

The two lustful canines started to move in tandem with each other. Joshiah braced himself the best that he could in his bondage, and pushed his tight rump against the toy, as Rose worked her fake cock into her brother's back end like a seasoned veteran, slowly picking up the pace to let him adjust. "Well...nngh...if you really have some plans, you better..." Joshiah paused, letting out a pleasured moan, "You better get on them, fast...I never thought I'd enjoy this so much...I can't last like this!"

Pleasure rippled through the heated vixen as her brother warned of the impending climax. In her heart of hearts, she was torn between truly railing her brother while she had the chance, and what she had been planning for all this time. The desire for a kinky, messy finish slowly started to give under her lust for her brother's seed, and with a quiet, slurping pop, the hefty fake cock slipped from her mate's tailhole and hung harmlessly before the stretched opening. "Don't keep me waiting then, my naughty pet..." she growled hungrily, yanking the feeldoe from her snatch and leaving it carelessly on the floor, and leaving her body empty of the vibrations, and needing to be filled. "Your mistress is right on the verge herself...and she needs a good, hard dicking, now!!"

With the toy removed, Joshiah felt as though the weight of submission had been lifted a little, and his spirit to please his mate was revitalized. He was no longer a victim, but a pet with a mission. "As you wish, my mistress sister..." he murred, his own voice low and almost soothing as his cock throbbed in the open air, dying to feel his sister's passage. It didn't have to wait long, as Rose climbed atop his body and straddled him, her soft, glistening labia spreading themselves over the tip of his length, and with a quick thrust of the hips, his member disappeared, engulfed in his sisters treasure.

"Good boy...ooooh! And don't you dare hold back on me," Rose commanded, leaning away to straighten her back, pushing her hips forward so that every single inch of her brother's cock could fill her to the fullest. Her claws gripped tightly onto his strong, toned legs, and tugged at his flesh as she started bucking herself closer to orgasm.

Her brother couldn't have stopped his climax, even if he wanted to...and part of him truly did want to. "But, wait...Rose...what if...ooh...what if I cum inside of you? I love you, but...I can't...I just can't...nnghfm-

In that moment, Rose stopped being his sister, stopped being his mistress, stopped even just being a sexual partner...and decided to make him her mate. With a swift and gentle touch, her paw cupped and caressed the face of her kin, and she leaned forth, pressing her soft, dainty lips upon his own, silencing any concerns or doubts Joshiah could have about his actions.

Without another thought, Joshiah relaxed, and every muscle in his body started to contract with a pleasure he'd never known in any other orgasm before. His knot burst forth from his sheath, and with almost no effort, pressed easily against his sisters deliciously tight vulva, and right into her body, joining them together in the sort of embrace that they'd avoided for so long. With their lips sealed, there was no howling, no chorus of pleasured moans, but only whimpers of ecstasy; quiet in sound, but speaking volumes to what they felt. Tongues lashed against each other, and fangs pressed to the delicate flesh beneath as Joshiah's sack tensed, and a rush of thick, warm, sticky seed filled his mate, and the pulsing rush of such voluminous liquid sent Rose over the edge right after him. Her paws gripped tight onto his shoulders and her claws dug in to the tough, tense flesh as she pounded her hips into his body, desperately thrusting against him even as his knot kept them completely tied. Having waited so long for this moment, her brothers cum started overflowing from her well filled passage, drizzling down her thighs and back over his sack as each pulse sent for a burst of fresh seed, and sent Rose into another, smaller climax, like the aftershocks of a massive earthquake. Her whole body shuddered as she nearly fainted from the pleasure, but she held on, not wanting to miss out on this moment for anything in the world. Nothing could tear her away from her brother in this moment, even as his incestuous seed started to nearly inflate her womb.

Just trust me, my brother...that everything will be all right.

**

Light trails of smoke drifted away from a slowly smoldering cigar as Joshiah looked over the balcony of his apartment.

Not too long after graduating high school, the young wolf had taken up a job working on the railroads and moved a little bit out of town, and the next thing he knew, he was all on his own. His friends all went to college, his family stayed back in the old town, and the only girl he'd ever really grown attached to moved away to a private school after seeing a thankfully negative pregnancy test.

That was all three years ago.

It was rare enough that Joshiah wasn't alone at home, anymore. He had no roommates, and had only made a couple friends in his new location. The occasional girl would follow him home from the bar, and he might have a cheap romp, but nothing was truly clicking with him. There was rarely affection, and certainly no connections like the one he felt before. He'd tried to let the whole thing go and be a part of the past...being in love with your sister for a lifetime wasn't a way that someone could live, much less, a way that they should.

"At least it's the weekend. I haven't seen the Sox play in forever..." he mused quietly to himself, tossing the stub of the cigar off his balcony and into the grass by the street. He stepped back inside his rather luxurious apartment and slid the door closed behind him, only to find that someone had come to his door when he wasn't looking. Out on the balcony, he never heard the knock.

Who the hell would be visiting me right now...?

Cautiously, Joshiah opened his front door, only to receive the shock of his life.

"Hello, little brother. Miss me much?"

There, dressed in a slim, black pencil skirt and a business jacket with a white dress shirt was Rose, looking every bit the part of a woman who had already gone far in life, despite being so young still.

"...More than you could ever imagine, sis," Joshiah said, his voice almost empty, as he wasn't quite able to assess the situation right just yet.

"Gonna let me in, or should I just stand here a little longer?" Rose asked, smirking at her dumbfounded sibling.

Joshiah stuck his tongue out and reached out into the hallway, pulling his sister inside, and into his arms for a tight, warm embrace, much needed, and thankfully returned. "Oh, get your ass in here!" he chided, chuckling quietly as his emotions kicked back in finally, and he realized he wasn't dreaming.

"That's a bit more like it!" Rose said, yelping a bit as she was nearly yanked off her footpaws. She gave her younger brother a quick, tight squeeze before letting him go, and kicking her heels off by the door. "Have you been smoking...? When did you pick that up?"

"I just had a cigar...trust me. Cigarettes are still nasty," Joshiah pointed out, closing the door behind her and gesturing to the couch. "Go ahead and take a load off...can I get you something to drink?"

Rose sauntered over to the couch and plopped right down, unzipping the base of her skirt just slightly so she could relax. "An amaretto stone sour would be lovely...work was a disaster today."

Joshiah rummaged through the cabinets in his kitchen, finding none of the proper ingredients, so he simply grabbed a glass, tossed some ice cubes in, and mixed her up a rum and coke, tall and stiff. "Yeah...I'm not sure that you understand...we don't live at mom and dad's anymore," he teased, handing her the glass with a smirk. "That will have to do, I'm afraid."

"That works," the vixen said, taking the glass and taking a large drink with a refreshed sigh. "Mnn...I should look you up more often. Service with a smile, and not too bad looking, either!" The vixen jested, giving her brother a wink to show that she was probably just teasing.

Joshiah almost felt the need to caution his sister about saying such a thing, but as she winked, he just fought off a blush and started mixing himself a whiskey and coke. "I'd gladly welcome the company, but...I gotta admit, this is a bit random. I don't see you outside of Christmas and Easter for a couple years, and then, you suddenly come and look me up, out of the blue?"

Rose took another quick drink, as if she wanted to avoid the question, but she knew that she couldn't do so forever. "Well...to be honest...things are going great, Josh. I have a very nice paying job working at a school in closer to the city, I'm working on finishing my degree, and I have a place, well...almost as nice as this one. The only thing I really haven't been able to make work is my love life..."

"You don't say..." Joshiah said softly, pouring a healthy dose of whiskey over a couple of ice cubes, and deciding to skip the coke altogether. "I guess we have a similar problem, then. They just don't make 'em like you anymore, sis..." A wink was given in return, as if the wolf wasn't speaking the truth.

"Been striking out a bit with the ladies? I can relate...maybe a little too well," the vixen admitted, sighing quietly and downing another chunk of her drink. "And...I can't stand it anymore. Josh...I..."

"What...?"

Rose set her glass down on the drink table in front of her and stood up, turning to face her brother. "One more time...I know we said we'd never do it again, we made a rule against it...but...I need to have sex with you just one more time...and then I'll never ask you for it again. I know I said I wouldn't, but..."

Joshiah was in the middle of taking a drink, and he nearly spit it out as his sisters request rang in his ear. They had made a rule...there were too many times that they'd nearly been caught, too much attachment to let it go any further, and no realistic future in which they could truly be together...but as he thought it over in his mind, he decided...

"Rules were meant to be broken, sister..." he whispered, setting his glass on the counter and stepping around it, taking his sisters paws in his own to try and calm her worried spirit. "I...I've been needing you, too...all this time, no one has ever come close...no one will ever compare to you...so again, just this once, one more time..."

The wolf was silenced by an affectionate kiss, and in that moment, he knew that all the other rules no longer applied, save for just one...

No telling mom and dad.
