#38 of Incest Stories (Others)

Old habits die hard, and traditions die even harder. In this story for Serinthia Kelberry and ragnar9, we see a trio of siblings who are worried their favorite tradition might be coming to an end!

College is getting ready to potentially separate Timothy and Samantha, and their older sibling, Thomas, might finally be getting out of the house, as well. Their parents are an affluent couple who often leave for long weekends, leaving the young adults home alone, to their own devices, and that always sets the stage for a weekend of intimacy.

Believing this could be one of their last ventures, the trio put everything out in the open, exchanging their passion and concerns, as much as their sexual energies.

As always, read, comment and enjoy!


The moment that the door closed, and a set of happy, loving parents were on their way down the walk, grins appeared on younger muzzles in the house behind them.

A responsible mother and father, they didn't have any idea about the secrets that they left behind, whenever they went away for a weekend trip. Their children were all young adults now, legally able to be out and on their own, but in that magical summer between high school and college, all three of them were still trying to figure out the next place that they would call home.

If all three of them went to different schools, it might spell the end of their ritual, and none of them wanted to bring an early end to that.

"Are they in the car, yet?" Samantha asked. She was technically the youngest of the trio by mere minutes, but that didn't stop her from being the most eager to get things started, when she knew that her parents were out of view of the house.

Her twin, Timothy, was standing by the front door, gazing through the tiny window that was built into the framework. "They're pulling out of the drive...waving...aaaaaand they're down the street," He explained, watching with a quick wag of his tail. "Don't think they forgot anything this time...should be safe to-

Timothy paused as he turned and saw Samantha quickly slipping her skirt down over the course of her thighs, allowing the flowing, pleated fabric to swish back and forth as she did. She knew that their eldest brother, Thomas, would be enjoying the view from the couch, as she bent forward and stuck her rear end up, pressing the tight, delicate folds of her womanhood against the crotch of her panties.

"...Yeah," Timothy finished after his stammering pause, "D-do that."

The offspring of a tall, handsome wolf and a gorgeous, slender raccoon, Samantha and Timothy took more after their mother and her softer features, whereas Thomas was almost a carbon copy of his father, embracing the powerful, lupine genetics that he was so lucky to inherit.

Being the oldest brother, he often saw his younger siblings as something of a plaything, and though he had the strength to enforce such, he never had to use it. It was by happenstance that he walked in on Timothy and Samantha in the throes of passion when they were just young, awkward teenagers, and in his good fortune, they didn't turn Thomas away.

They welcomed him into the sexual frenzy, and ever since, the years that followed were filled with the siblings counting down the days to the next trip their parents were taking.

"Can't really blame her for being so eager," Thomas suggested. Samantha was already hooking her thumbs into the hips of her bright, pink panties as she began to tug them down, and at Thomas' words, she cast a sultry gaze to Timothy, knowing that he'd get the hint to come and help her out with her top. "There's no telling how many more times we'll be able to do this, you know. I'm almost done with college, and you two could be miles and miles apart, depending on what you choose to do."

The small gap of years between Thomas and the twins did create a greater maturity in him, where he was able to see the reality of their incestuous pastime. They just couldn't keep doing this forever, and as much as he always enjoyed himself, he knew that he, too, would have to grow out of the bad habit before too long.

That being said, he wanted them to enjoy the few opportunities that they'd have left to the fullest.

"We'll cross that bridge when we come to it," Timothy suggested, giving the same answer that he had that entire summer. The thought of having to live without the sexual attentions of his older brother and younger sister was one he willingly avoided, as he opted instead to slip his paws under Samantha's tank top. His open palms settled against the slim lines of her abdomen and caressed their way up to the underside of her bra, and as he paused and cupped her breasts, Samantha reached back and unhooked her bra, allowing it to stay only by virtue of Timothy's touch.

The matching pink brazier fell to the floor in the next moment, and Samantha, having had all of the same despairing thoughts of their routine ending, pulled her brother's paws by the wrists and forced them to tightly squeeze her breasts as she leaned in and pressed her lips painfully tight to his own.

"That's the way," Thomas murmured from the couch as he watched and slowly unzipped his jeans. He always felt particularly close to his siblings, even before they began their forbidden games, but he knew that the twins shared a bond that he could never understand, and he could hear the feverish panting in their voices as Samantha emptied her passions into her brother's muzzle. Her paws wrapped around the back of his head, and pawtips entangled themselves into bright, vibrant tresses of blue as she kept him in close, refusing to be denied the lengthy exchange. "Give him everything you've got, Samantha. Let him know how much he means to you."

Against the front of his jeans, Timothy felt a familiar pressure building, and Samantha lifted her leg, wrapping it around Timothy's lower back so that she could grind her bare crotch into the growing bulge. "Mnnnf...mnnngh!" she moaned throughout the length of the kiss, refusing to allow the physical touch to drown out the ballad of her feelings for her twin.

Timothy's ears perked to the sound, and his eyes winced shut even tighter as he felt the familiar, warm moisture of his sister seeping into the crotch of his jeans and exciting him more than he could ever need to be. His own groans of delight were muffled by his sister's tongue, as it slipped forth to wrap around his own and dance with it in incestuous passion, and his legs began to tremble from the pleasure of Samantha grinding into him with such intensity.

"You know...mom and dad are gone for the whole weekend," Thomas pointed out, as if the twins didn't know. "There's no need to torture yourselves any longer. Just get fucking already."

Samantha paused the kiss and cracked an eye open for a moment, opting to turn back and gaze at Thomas. She snickered the moment she saw the bright, pinkish-red tip of his canine member sticking out through his boxers, and she could see the swelling in the orbs of his sack as he playfully stroked his cock, enjoying the show of his own siblings sexual exploits.

"Sounds to me like you're the one being tortured," she pointed out, as she pressed another quick, firm kiss to Timothy's lips. "You just want us to get right to the action so you can join in...isn't that right, big brother?"

Thomas was caught in the act, and no doubt, Samantha was partly to blame for his growing erection. She knew that he'd enjoy the show of her panties coming down so slowly around her thighs and ending up on the floor, complete with the tiny, but profound stain of her wetness upon the crotch. It was only a matter of seconds before he started teasing his own flesh at the sight, and now, Samantha was stuck between a pair of horny, needy males...both of whom happened to be her brothers, and further, both of whom had been saving their orgasms for over a week in anticipation of this moment.

Samantha knew what a pain it could be for such a virile young man to intentionally hold back from release for such a long time, and she would have been a terrible sister to leave her siblings hanging in such a state.

"Very well then, boys. I can see just how swollen you both are," Samantha teased, taking the lead role despite being the youngest of the three. "If you've got something to give me, hurry up. It's rude to keep a lady waiting."

Timothy leaned toward being timid and shy overall, but with the heavy amount of seed in his sack, he couldn't live up to that role at the moment, and naturally, Thomas wouldn't have any problem bending his sister over. It was all a matter of what she preferred that afternoon, and whatever her choice was, Thomas had lube on hand, if it was required.

There were worse decisions to be stuck between, but Samantha always had trouble choosing if she wanted to suck her twin while her older brother took her from behind, or if she wanted to stand between them and be sandwiched.

Taking the middle ground, she licked Timothy's cheek and pounced him down to the floor, lifting her tail for Thomas on the way to the ground.

"I got tired of waiting," she murmured under her breath, as she reached into Timothy's jeans and fished out the growing length of his cock. It was still pulsing to a full hard-on as she held it in her paws, and the touch of her glistening, pouting folds against the very tip was all it took to leave Timothy stiff as a board.

The male twin snuck a quick lick back to Samantha's cheek as he managed a wry grin. "I'm n-not complaining," he suggested, as he felt his sister lowering her hips, dropping her womanhood onto his shaft. She gritted her fangs and adjusted to the delicious fullness that her brother provided, and held still for a moment as she waited for Thomas to line up with her body.

The lupine sibling was pressing the tapered tip of his canine length up to the exposed pucker of her tailhole the moment his knees hit the floor. Samantha was used to Thomas having a preference for her rear end, and despite how tight she was, she'd become accustomed to the feel of his manhood inside of her.

There was something delightful about the feeling of the thinner tip sneaking into her tight, eager passage, followed by a slowly widening shaft, and Thomas was surprisingly gentle with his younger sister, as she was speared between a pair of incestuous cocks.

"T-This...this won't be the l-last time, right?" Samantha asked, panting heavily already, just from the effort of being so completely filled up. "We...w-we can keep doing this?"

Thomas could never lie to his siblings, least of all his young, sweet sister, but he knew that their opportunities would be few and far between as the summer months came to a close.

Even if he had to literally make the time, he wouldn't allow this to be their final coupling.

"Of course we can," he replied, keeping the stammering moans from his voice until he pulled his hips back and gently bucked them forth again. With a quiet slap, his full, heavy sack bounced against her inner thighs, and before she could let out her cry of ecstasy, she was bucking down against Timothy, who met her in the middle.

No matter how many times the three siblings met in a sexual act, Samantha couldn't remember a time that she felt so blissfully full, and as if her brothers could sense it, they kept a perfect timing with her, never allowing her body to be empty.

Leaning over her back and keeping her pinned into Timothy, Thomas gently pounded his hips against her full, perky rump and watched as his sack swayed into her body on each pass. Timothy couldn't give her all of the same force that Thomas could, being pinned, but Samantha gazed into his eyes tenderly, as if to assure him that he'd already done more than enough to satisfy her needs.

He was there for her in a more emotional way than their eldest sibling, and he could feel her appreciation for the same whenever she bounced her hips all the way down and completely impaled herself on his length. Her inner walls hugged and squeezed at his member with forbidden affection, and as the pace increased, and pleasure built, their lips met once more, under the watchful eye of their older brother.

I don't care if it's wrong, Thomas thought, as his knees dug into the carpet and his thrusts became choppy and desperate. This kind of passion...this kind of love between them...this is something I could never have stopped. I can only thank them for letting me join...

His thanks was in the form of just what Samantha wanted, as she felt warm, streaking seed pouring across the inside of her ass. The tight, gripping passage was filled with the mess as Thomas released her hips and gripped his own knot to keep from tearing his poor little sister apart, and as he pulled it free, cum spilled from the gaping entrance, and the last ropes of the mess fired across Samantha's back, leaving her happily marked.

In their youthful inexperience, the twins bounced against each other rapidly, trying to hold the kiss the whole while. "Nnn! _Mnnnf![/b]" Samantha refused to break the bond of their lips, even as each raccoon reached their peak and trembled with untold, forbidden pleasure. Cum flooded inside of Samantha and poured straight into her womb as she bucked down on Timothy with such a harsh thrust that the poor boy was nearly winded by it.

A small trickle of her own orgasmic juices spilled away from Samantha in the aftermath, as wet and silky arousal dripped down over Timothy's depleted sack. The excess build up of cum was still dripping out of her cunt and staining the carpet, as well, as the boys blessed Samantha with everything that they'd been saving for her.

They were empty, but they were nowhere near spent; there was still a whole weekend ahead of the incestuous trio, and they were just getting started._
