#3 of Tailmouths

My tailmouth infatuation continues, and now I've come up with two of my own! Introducing twins Autumn and Simon, and their tails Rain and Quest.

The initial concept art for the two (four?) can be found here - http://www.furaffinity.net/view/5820420/

I wrote this short story up as an official introduction for them. It's short, but hopefully this will flesh them out a little and maybe even make you fap at the same time. It contains a sort of 'sampler plate' of themes that I plan to expand on later.

I know this isn't my usual thing, so people who watch me for my pokemon stories will just have to bear with me.


Despite his physical exhaustion, Simon lay staring up through the darkness at the ceiling above his bed, unable to sleep. More than that, his cock was rock hard and he needed relief.

Shifting his gaze from the ceiling, Simon regarded his tail. Quest was curled up silently beside him, apparently not sharing in his insomnia. They were technically one being, Quest being his tail, but they were otherwise seperate entities in all respects. simon considered waking him; Quest was always happy to suck him off, but then thought better of it. He was in the mood for other company tonight.

Rolling over carefully, Simon's hands explored the bed beside him until they came to rest on the furry body lying beside him. First his fingers moved gently up her back, then along the slope of her shoulder, then moving to her front and finally coming to rest on her left breast. Her bust was modest, barely a handful, but to Simon they were perfect. He found one of her pert nipples and rubbed it slowly.

She stirred, either woken up or having been awake the entire time. Trying to pull away from him, she muttered "Simon, please... I'm trying to sleep."

Simon ignored her plea, rising onto one elbow and leaning in closer. She whimpered as his hand continued to roam across her body. He squeezed her breast erotically, then moved the hand further down along her belly, searching for the tender spot between her legs. When he found it, he ran one finger along the furry slit.

"Don't be that way Autumn. You know I could never keep my hands off you," he whispered in her ear.

They were brother and sister. More specifically, they were twins; Simon was just minutes older than Autumn. That did nothing to dissuade Simon from his current course of actions, however. They had been in an incestuous relationship for years now, the forbiddeness of their sexual liaisons only fanning the flames of his passions for her. For her part, Autumn never instigated it, but neither did she do anything to stop him from having his way with her.

Of course, Simon wasn't alone in his incestuous lust. A voice filled with desire hissed at him through the darkness. "Yes, fuck her. Roll her over and make her beg for her brother's cock."

Simon felt a wetness flick against his ear, and he knew that it was Rain. In stark contrast to Autumn's submissiveness, her tail reveled in all of the sordid acts Simon could see fit to put them through. Rain was especially fond of teasing him into using his twin sister's body to sate his urges. She was a constant co-conspirator, always urging them on to dirtier and more extreme acts of perversion.

"You're the most beautiful girl in the whole world, sis," Simon encouraged his sister. He pushed a finger inside of her and siddled up closer until his erect penis pressed against her bottom. Then he made a slight thrusting motion, humping against her and sliding the shaft of his cock against the root of her tail. His intentions were clear, and she knew he wouldn't be satisfied until he got what he wanted.

"Fine," she said finally. "But do it quick. And be gentle, please." The words sounded sincere, but to Simon they seemed more like a dare.

Autumn rolled over and got up onto all fours. Her brother wasted no time in assuming his position behind her. In the darkness, he could barely make out the shape of her body, so he leaned over and flicked on the bedside lamp. Then, in the soft light, he regarded her lovingly. Being twins, they were very similiar; the light brown fur of her back was dappled with white markings that ran all the way down her tail. From this vantage, all that was visible of her head were her perky ears and a mess of dark green hair streaked with purple. Many of her friends had been surprised when she'd dyed the purple streaks into her hair. She had always been a very conservative girl, after all, and shy to a fault.

In truth, she had done it at Simon's request. Ever since they had become lovers, everything she did was to please him. It was an act, all of it - the shy girl that everyone thought they knew was only a mask for the kinky girl underneath. Even though she gave no overt signs, Simon knew that the sordid things they did together turned her on just as much as it did him. She would protest, say that what they were doing was wrong, then moan like a whore and shake with orgasm when he shot his load into her and called her sister. She loved to be used, and she loved him. When he'd asked her to dye her hair for him, it had been a simple thing.

Rain's voice snapped him out of his reverie. "What are you waiting for? Take her from behind like the bitch she is." She had twisted herself around Simon's torso, leaving him unobstructed access to her pussy. The tailmouth's green tongue darted out from underneath them, running along Autumn's furry slit wantonly.

Galvanized by Rain's dirty talk, Simon grabbed his sister by the hips. "I'll make it quick alright," he said. "But it won't be gentle!"

Below them, Rain pulled away and purred in delight as he thrust his cock into his sister's wet hole and made good on his promise. Simon was done with foreplay and teasing; now there was just pure, animal lust. He slammed Autumn's backside hard and fast, and she braced herself on her elbows, burying her face in her pillow and trying to remain silent. Her restrained behaviour only encouraged her brother's aggression, however. Riding her hard, he grabbed her hair and pulled her head back. A small gasp escaped her lips, but she did nothing to free herself from his grip. Her pussy clenched down around his shaft, betraying her excitement at the rough treatment.

Meanwhile, Simon could feel something thick and wet - Rain's tongue - playing with him from below. His sister's tailmouth licked at his balls, then moved to slither around the base of his cock as he thrust it in and out of Autumn's dripping wet pussy. Juices from their lovemaking trickled down Rain's tongue and dripped into her open mouth, and she grinned toothily. She loved the taste of the twin's mingled lust. Then another tongue joined hers. Unsurprisingly, Quest had been woken up from his slumber. Simon's tailmouth rarely spoke, and he had joined in on the fun silently. While Rain focused on the spot where the two twins were erotically joined, Quest went to licking his partner's balls, still wet with Rain's saliva. The two tailmouths rubbed against each other in mutual affection as they worked on bringing Simon and Autumn off even faster.

Simon leaned down over his sister and yanked her head further back so that he could whisper in her ear. "Do you like it like this baby?"

"Stop," she whimpered, pressing her ass back against his pounding hips.

He did not relent. "You're my slutty little sex toy, sis, and everyone knows it. Does that get you off?"

Despite their forbidden relationship, the twins were less than discreet. In fact, Simon loved to flaunt their incest in front of others, and although she pretended otherwise, he knew that Autumn felt the same. Often Simon would come home to find his sister's girlfriends were over. He and Rain would give them a sly smile as he grabbed Autumn by the wrist and pulled her into the bedroom for a quick fuck session. Usually he would have the decency to shut the door behind them, but sometimes he would leave it open, leaving her company to listen to the sounds of their incestuous liaison and inviting them to take a peek if they dared.

When Simon was finished, he would casually stroll out into the front room. Autumn would follow closely behind, eyes downcast, her clothing and fur disheveled and sometimes stained, depending on where her brother had blown his load. Quest and Rain would grin, licking their lips in satisfaction. Autumn's friends would stand there awkwardly as Simon left, the bolder among them stifling a giggle. Then they would assault their poor friend with all manner of questions. Simon wondered what his sister told them after he'd left; certainly not about how she'd bite her pillow to hide her cries when she came.

Simon's friend's were all aware of the goings on as well. What's more, Simon would often have his sister service them. At a word from her brother Autumn would sink to her knees and obediently suck them off with Rain's help, sometimes while Simon took her from behind.

She loved it all and they both knew it, but instead of answering, Autumn let out a strangled moan. Satisfied with the response, Simon straightened his back, gave her hair another playful tug and rode her hard. His sister's tight pussy and the two tongues working them both over were pushing him over his limit quickly, and as much as he wanted to hold out, he knew he wouldn't last. Still, he wanted to make Autumn cum first, and he had one last trick up his sleeve.

"I'm gonna cum in you, sis," he panted. "Maybe this time I'll knock you up."

It was her most secret desire, to bear his incestuous children, and hearing it spoken aloud right before he came always drove her crazy. At that exact moment, Quest's probing tongue found her sensitive clitoris. Autumn let out a series of cries of "Oh!", quiet at first, then growing louder and more passionate until Simon was sure all of the neighbors could hear; with her head craned back, there was no burying her face in her pillow this time! Her back arched and the walls of her pussy squeezed the shaft pumping in and out of her rhythmically. His beautiful sister was cumming.

His mission successful, Simon buried his cock as deep as it would and, with a grunt of relief, stopped holding back. He could feel his own orgasm approaching quickly; a burst of pleasure surged through his loins, and he exploded inside of Autumn. Thick cum flooded her warm depths, filling her pussy and gushing into her fertile womb. The feel of his warm seed spreading through her intensified Autumn's orgasm, and she squeezed down on him as best she could, desperate to keep his cum inside of her. It was hardly necessary, however. After the first few spurts, the base of Simon's cock began to swell, his knot tying them together and preventing any of his seed from escaping.

Rain hissed in delight, and Quest growled. The two tailmouth's licked and nibbled relentlessly at the twin's privates. They probed Simon's knot, searching for any semen that had dripped out, but there was none to be found - they would have to wait patiently for the bulge to shrink. Instead, they had to satisfy themselves with licking up all of Autumn's sweet juices. The two tailmouth's tongues ran along the lips of the girl's pussy, fighting for every little drop, until their tongues entwined and the licks evolved into an open-mouthed kiss between the two tailmouths.

While their tails made out underneath them, Simon let go of his sister's hair and slumped down over her . Totally sated now, he nuzzled her and kissed her neck gently. Autumn did not respond; instead she closed her eyes and focused on the feeling of her brother's knot filling her up. Slowly, she contracted the muscles in her pussy, squeezing the shaft trapped inside of her in an attempt to milk every last drop out of him. It wasn't long before she triggered her second orgasm, less intense than the first but no less pleasurable. Autumn shivered beneath her brother and bit her lip, riding out the waves in silence.

They stayed there like that for a while, tied together; Autumn on all fours, panting heavily and bringing herself to orgasm after orgasm, with Simon lying on top of her. Finally, his knot began to shrink. When it popped out, it was followed immediately by a torrent of semen. Rain and Quest were right there to fight over it; the two naughty tails pushed each out of the way, trying to catch as much cum in their mouths as they could, then swapping it back and forth in a series of gooey kisses. Simon flopped down onto the bed beside his sister as their tailmouth's attacked her exposed pussy. They pushed their tongues deep into the squirming girl in search of more delicious cum. To them, cleaning up the sibling's mess was almost as much fun helping make it.

"Thanks, Autumn," Simon said to his sister. "You're the best sister a guy could ask for."

Rain raised herself up for a moment, grinning and licking some stray cum from her maw. "Yessss," she cooed. "Such a good whore."

Removing his tongue from Autumn's furry slit, Quest turned his attention to Simon's cock. He nuzzled the flaccid shaft, licking it tenderly. Simon reached down and stroked his tail. "Sorry to wake you," he said. "Don't worry, I'll be ready to give you a good meal for breakfast."

Quest grinned at his partner. He always loved his meals straight from the tap.
