Sarah, a young female mink, is doing all she can to endure her yearly heat. If only she could get some help with it...


I have returned, after much too long of an absence, and bring with me a light, pleasant story. It does contain brother/sister incest, so my apologies if that isn't your particular cup of tea.

The first Saturday of summer vacation found Sarah at home, hunched before her computer, typing furiously away with the one paw that wasn't stuffed down the front of her pink cotton panties. It was approaching dusk, the orangey-red light of a dying sunset beaming through the cracks of her tightly drawn blinds. It shone upon her screen in such a way that she could see herself palely reflected; a scruffy little mink with dark eyes and messy pink-dyed hair, her ears pinned and expression sullen.

She'd been trying to appeal her ban on a fan-fiction forum for the past three hours, all to no avail. Somewhere in the back of her mind, Sarah knew that this was definitely pretty lame, but the rest of her burned with righteous indignation. So what if she'd called someone a few bad words? They'd made fun of her story! And true, it was kind of a bad story and the slash pairing didn't make a lot of sense, but...well...

Shit.

It was tough to keep any of her thoughts straight with the hot, insistent burn throbbing non-stop between her legs. Sarah's first heat had only been the year before, towards the end of her junior year in high-school, but she didn't remember it being this intense. She certainly hadn't kept sticking her paws down her pants at every opportunity. Maybe all of the classwork had kept her busy. This year's heat had waited until the day after graduation to show up, so now all she could do was hunker down and wait for it to be over.

Her eyes kept straying to the row of tabs arrayed neatly at the top of her screen. 'Alpha wolf rails bratty bunny' and 'slutty tigress cop interrogation' were the first in line, but she'd seen them before. And the acting was really, really bad. Normally, something like that didn't stick out to her, but she'd been watching a lot of porn since her heat began. Even if the slutty tigress cop had perfect tits, she couldn't deliver her lines worth a damn, and the astonishingly well hung alpha wolf was not very good at being alpha. It was all so tiresome.

Sarah leaned back from the screen with a groan, still busily pumping a pair of fingers into the slick heat of her intolerably needy cunt. Tiny pale arcs of static crackled where her fur rubbed against the fabric of her panties. The terrible part of being in heat was that no matter how bored she got of being constantly aroused, getting herself off never stopped feeling great.

...If only it wasn't so much work. Her wrists were starting to get sore and simply diddling herself felt downright robotic now that she'd done it a dozen times in a row.

It had occurred to her that she could probably find herself a hookup, but though the thought of having a real live person come and fuck her silly made Sarah feel giddy with lust, it also deeply terrified her. In the whole of her eighteen years on the planet, she had never done anything of the slightest lewdness with anyone else. Unless she counted internet role-play...which of course she could not.

Sarah made an unhappy noise, then forced herself to stand up and stop with the fingering for a little bit. Even this was a challenge; she felt twitchy and warm, filled with a desire to lie back and shut her eyes. Someone--anyone--could come, spread her legs open and take her right there on the bed. She...

She was touching herself again. Goddamnit.

"Go downstairs. Get a glass of water." Sarah said to herself, the instructions coming as a harsh growl.

Sarah's room was in the attic, up a steep flight of stairs from the main floor of the house. She took them one at a time, hating how rubbery her legs felt. She was only wearing a hoodie and her panties, but that was fine, it was just her and Aiden at home. Her older brother had returned from college two days before...slightly too late to see her graduation. Then of course she'd been stuck in her room, heat addled, so they hadn't seen much of each other. As a capper, their parents had blithely said farewell and gone on a three week trip abroad. Sarah knew better than to complain; plenty of other people her age would have killed in order to be left unsupervised for part of the summer...but in truth she just felt lonely.

Once her heat was past she'd go give Aiden a big hug and then he'd drive them out to the bowling alley, where there was also a bank of retro machines (Sarah held the high score on everything but Street Fighter II, where Aiden was just too good at spamming kicks). She had a driver's license of her own now, but in her mind it was Aiden driving. Everything would go precisely how it had back before he'd left for school.

They'd go to the movies and make fun of the hokey local adverts which ran before the feature. They'd ride bikes through the woods and shoot off bootleg fireworks on clear nights. It all sounded wonderful.

Sarah got herself a glass of water and took her time drinking it, forcing herself to ignore the continual heated squirm between her legs. It was fine. Another day or two and it would be over. She looked to the clock on the wall, its face painted with a bucolic rural scene, and tried to make herself calm down. There were swans, hayfields and a cheerful fox farmer in a checkered shirt that was open halfway down his chest. Sarah took a deep breath, found her thoughts immediately going to what it would feel like to be knotted, and then violently shook her head.

"Fuck's sake..." She sighed, and was starting to resign herself to going back upstairs and watching the doings of the slutty tigress cop (with the sound muted, maybe), when she heard something through the floor. Muffled laughter, then movement.

Aiden's room was downstairs, and he clearly had a friend over. This was technically against the rules that their parents had given before they left (no friends, no parties, don't you dare touch the bottle of scotch in father's office, etc. etc.). Normally Sarah wouldn't have minded, but she thought she knew which friend Aiden had invited. There was something familiar about the sharp, yipping noise of his laughter.

It had to be Jake, one of his old friends from high school. Sarah did not like Jake, who had always struck her as arrogant and a little bit mean. He was a coyote, with sandy fur and mischievous yellow eyes. He'd delighted in teasing her whenever Aiden hadn't been looking, and had even once put gum in the fur of her tail. There had been an embarrassing short patch for _weeks. _

Sarah blew out a breath, set her glass into the sink with a clunk, and decided to go and scold her brother. This wouldn't actually do anything, but she felt disgruntled enough to give it a go regardless.

She tiptoed down the stairs, hoping to make a sudden, startling entrance. Giving herself a definite objective helped a little bit with the heat, but even now it was a struggle to keep her thoughts in line. She wondered, with a hint of worry, what she might say once she burst into her brother's room.

...Actually, scolding no longer seemed like the way to go. Not only wouldn't it accomplish anything, but she wasn't exactly an imposing presence; five feet tall on her tiptoes and practically buried in the loose fabric of her hoodie. Or...not hers, exactly. She'd taken it from Aiden's closet after he left for school and worn it the whole of the first autumn he'd been gone, until the last traces of his scent were worn away.

Sarah paused on the final step, her brother's bedroom door firmly closed just in front of her. Why was she thinking about that?

Aiden's door had a triangular yellow placard in the shape of a roadwork sign. On it, written in messy black letters, was: WARNING: BIG BROTHER AHEAD. She'd made that for him when she was five or six, an arts-and-crafts project brought home from school. Even though it was faded and the edges of the construction paper were starting to curl, he'd never taken it down. Sarah, despite herself, felt genuinely charmed that he'd kept it for all these years.

Maybe she'd just go and say hi. That would be fine.

Sarah pushed open the door.

Aiden's room was rectangular in shape, with a bed directly ahead of her and then a television mounted upon the rightmost wall. Aiden had managed to drag a gray fabric sofa down the stairs at some point and kept it front of the television. The lights were off and the room dim except for fading streamers of sunset orange coming through the window and then a blaze of color from the television. Aiden and Jake were lounging on the sofa, Sarah could see the backs of their heads, Jake's sharp ears perked. The coyote was saying something to her brother, his tone low and excited.

Now that she was in the room, Sarah suddenly felt dizzy. There were new scents in the air, warm and distinctly male. A few rational thoughts squirmed to the forefront of her mind, insisting that this was nothing new, but now a hundred ancient instincts were all firing in unison. Everything between her legs quivered and then clenched. She thought for half a moment about turning around and leaving--this was what a rational person might have done--but every motion that might have let her do that was suddenly frozen.

And suddenly she was standing at the back of the couch; Sarah couldn't remember stepping forward, it was as though she'd been drawn by some unknowable outer force.

"Hi..." She tried to say, then realized what was happening before her and was abruptly consumed by a cold pall of shock.

Up on the television screen a buxom black wolf and a meek red vixen, both wearing improbably skimpy military uniforms, had just been captured by masked insurgents.

"I won't break, no matter what you do to me!" The wolf insisted, her ample chest puffed bravely out. Her line delivery was...something.

At this, the vixen was tugged away, held between a pair of well muscled jaguars. The actress was trying very hard to look scared, but Sarah couldn't help notice the tip of her fluffy tail wagging. There was a tiny orange price tag hanging from the bottom hem of the vixen's uniform blouse.

"If we can't have you, then we'll have to make do with her!" The insurgent leader, a charcoal furred fox, said with a laugh. At this the wolf very dramatically caved and sank to her knees, reluctantly undoing her blouse.

"You won't ever turn me against my country--" She began to insist, then promptly had her mouth plugged by a thick vulpine shaft.

Sarah, feeling oddly paralyzed, let her gaze slide downward, past the television and to the couch. She was near enough to see over it now, down to where Aiden and Jake were lounging and--

"Oh!" She cried.

Jake and her brother were nude from the waist down, casually stroking themselves. Sarah's eyes darted jaggedly back and forth. It was dim in the room so she couldn't quite see everything, but the impatient red throb of Jake's canine member was obvious enough, leading down to a thick sandy furred sheath and then the round swell of his balls. Shock forced her heart to stand still and for a halfway panicked moment Sarah wondered if she was about to keel over. Her legs, already unsteady, nearly came undone.

The two boys before her scrambled around, equally surprised.

"Shit." Jake said mildly, his ears pinned out to the sides.

Aiden nearly fell off of the couch, then managed to grab a cushion and hold it over his crotch. His dark eyes were huge with embarrassed shock.

_"Sarah?! _ What are you doing down here?" He demanded.

For a moment Sarah was stuck for words. Her head felt somewhat clearer now and she was beginning to realize just how deeply embarrassing this whole thing had to be for everyone involved. Still, her eyes kept flicking out and down, almost on their own. Aiden had grown a bit during his time away; he was leaner and more toned, his shoulders definitely broader. He held the cushion at an awkward angle and Sarah realized that she could see a hint of his cock pushing out to the side. It took everything she had to look away. Jake had put a paw over his own groin but didn't seem to be working hard to cover himself up. Already there was a sly, halfway amused gleam in his amber canine eyes.

Shit. She had to think of something to say. Sarah wanted for a moment to be apologetic, then angry (but why?) and then simply to throw herself over the couch and hug her brother as tightly as she could.

"What are you watching?" She blurted instead. A needless question, but at least it broke the silence.

Slowly, Aiden looked back to the television screen, where the soldier wolf was being bent over and railed by a pair of very happy cats. Her uniform was in tatters.

"Just a...shit...sorry," Aiden managed a shaky smile. "I didn't hear you coming."

"You should've knocked." Jake said, but weirdly the coyote didn't sound very annoyed. His nose kept twitching and his eyes were all over her. The press of his gaze felt nearly physical.

Now that she noticed this, Sarah realized that Aiden was trying and failing to keep from staring at her too. She wasn't underdressed by any means, Aiden's hoodie came halfway down her thighs, but that wasn't what their attention had been drawn by. The slick wet need between her thighs burned worse than ever. Sarah had been so completely surrounded by the scent of her own heat for the past several days that she'd stopped registering it.

"Sorry." She heard herself say, but though a part of her mind insisted that she turn and leave before things could become any more awkward (if that was even possible), Sarah's feet remained rooted to the ground. Her heart was hammering. She noticed that both Jake and Aiden were still achingly hard behind their shoddy attempts at privacy. She could smell them, in the same way they could certainly smell her, instincts still ceaselessly firing. She had to ignore those. This was her _brother. _ Her brother and his no good coyote friend. She had to force herself to speak and say the correct, responsible things. "Just came to say hi. I'll get out of your fur..."

It took a huge effort even to shift her weight a little bit, to make herself begin turning. The thought of taking the stairs felt like climbing the north face of Everest. But, before she could move more than an inch, Jake reached for the remote and muted the video still playing on the television, uncovering himself for just a moment.

"She can stick around, can't she?" He asked. The question was directed to Aiden but Sarah felt the coyote's eyes flash meaningfully to her. He wore a sharp toothed grin at one corner of his mouth.

Aiden blinked, caught off guard. He opened his mouth a crack but said nothing. There was a slick gleam of pre staining the fabric at one corner of the cushion he was still ineffectually covering himself with. Sarah felt simultaneous pulses of lustful heat and curdled, shameful cold ripple through her. She shivered.

"...No, you're right," Jake said, flapping a dismissive paw. "She doesn't watch stuff like this."

At once Sarah felt a huge flare of annoyance.

"Yes I do." She blurted, before she could think better of it. In the back of her mind she knew that this was probably precisely what the coyote had wanted her to do, but she was too irritated and hot to put any deep thought into the situation. Jake's paw had slid slightly upwards now and he was only covering himself with his fingers.

"If you want to come and hang out with us..." Aiden said. He spoke carefully, still making a valiant effort to pretend like everything was normal. His gaze flickered to her and then away. The insides of his ears had gone a deep shade of pink.

Slowly, Sarah shuffled around the side of the sofa. There was a gap between Jake and Aiden and that was where she sat, allowing her legs to collapse.

She was smaller than both of them and the cushions in the center of the couch were slightly saggy, which seemed to emphasize the difference in size. Aiden was still trying his hardest not to stare at her but Jake's gaze remained perfectly direct. Casually, he took the remote and restored the sound, then lowered it by a few ticks. The wolf was moaning through gritted teeth, grinding down hard upon a fat vulpine knot. Somehow, Sarah found that she could ignore the television quite easily.

"So what do you like?" The coyote asked. "Do you like this? Group stuff?" Though he was surely only talking about the video, his eyes never left her. A funny, warm floating feeling expanded within Sarah's center, both embarrassment and not.

"Dude." Aiden said, a mild sort of warning in his voice.

Sarah managed a few fractured thoughts about the many, many tabs that had been left open on her computer upstairs, but could only helplessly shrug. A part of her wanted to tell Jake to bug off, that she'd only come down in the first place to see Aiden, but the fact that he was paying such direct attention to her was disorienting. There was still a bit of the same old coyote mischief lurking in his eyes, but so far he hadn't pulled any nasty tricks.

She made herself look at Aiden, but the odd fluttery feeling only got worse. A powerful urge rose to snuggle against his side and bury her face into his chest...but of course he was still nude from the waist down except for the clumsily positioned cushion.

...Why did that not bother her? Why did realizing this still not bother her?

"Must be tough, having to deal with your heat every summer." Jake said.

Sarah blinked, snapped from her thoughts. For a moment she felt halfway embarrassed but there was really no point.

"I guess." She said. It was tough to think, tough to do anything. This time she really did lean against Aiden. A muted shiver rolled through him, but he didn't pull away. Slowly, he shifted and then put an arm around her shoulder. They were so close now, her arm brushing against the cushion, mere inches from...

She shivered, fur prickling up. It was ridiculous just how sensitive everything felt, each part of her humming like an overloaded electrical wire.

"You're burning up..." Aiden said, touching her forehead with the back of one paw. Sarah wanted simultaneously to duck away from her brother's touch and to lean further into it. There was such gentle care in his voice. The flutter in her stomach deepened. She almost felt ill, but somehow not in an unpleasant way.

"It's just my heat." She mumbled. Now that Aiden mentioned it, she really did feel warm even past the need throbbing insistently between her legs.

"Maybe you should take the sweater off." Jake suggested. Though his tone was perfectly light and eminently reasonable, the glow in his eyes had not gone away. Sarah shuffled her legs up, realizing just a moment too late that doing so exposed the pink fabric of her panties, clinging tight to her rear and the heat slicked lips of her sex. She had to pull her tail in to be sure that everything was hidden, but even that movement put odd tremors through her center.

The idea of Jake seeing, of everyone seeing those parts of her, had become weirdly interesting. Sarah knew, in the back of her mind, that this was only the heat talking, but it was impossible not to give in just a little bit. Perhaps her tail was not tucked as firmly as it could have been, her legs not closed especially tight...

Sarah looked up at Aiden. She'd fallen into such a position now that she was practically lying on the couch, feet pointed at Jake, her whole upper body invading her brother's lap. He'd begun to squirm and was gripping the decency cushion very tight, but even now he made no move to get up or position her elsewhere. His arm was still around her, holding her close.

"Maybe..." She breathed. Jake shifted closer. He wasn't covering himself at all now, the red of his pointed canine shaft twitching in the open air. Somehow, this didn't surprise Sarah at all, though another powerful squirm of needy warmth twisted her stomach into a knot.

Aiden shuffled against the side of the sofa and Sarah heard the cushion fall softly to the floor, then his paws were at her waist, hooking into the hem of her hoodie.

"Is this one of mine?" He asked, warm breath tickling Sarah's ear.

"Yes." She said, her answer coming as a tiny gasp. She thought for a half second about saying why she'd taken it, but there were to many words. She could feel the hard press of his cock against her side and felt momentarily startled by just how solid he felt, how wonderfully thick.

"You mind if I have it back?" Aiden asked. He was breathing hard, everything past the outer facade of casual questioning filled with impossible tension. He felt like a spring that had been coiled too tight.

Sarah nodded, biting back a strange feral noise that had bubbled up from some deep, primal place within her. She wanted for an instant to say that she wasn't wearing anything underneath the hoodie--no bra, only the panties, and even those were soaked straight through--but her words failed. She put her arms up and let Aiden undress her, her breaths coming as jagged little huffs.

The fabric bunched at her chest for a moment and Sarah had to squirm. Jake made a low, surprised noise as her breasts bounced free.

"Holy shit," he said, eyes flashing to Aiden. "Your sister's _stacked." _

Sarah squirmed. She'd always been well endowed for a member of her species, her breasts round and firm, covered with coffee hued fur that melted to white as it ran down her stomach. Her nipples stuck out, black and achingly hard. Her fur was a mess, ruffled and all askew, but that hardly seemed to matter. Jake's eyes roved all across her, raising a nearly electrical tingle wherever it landed. Aiden let out a slow breath, tossing the hoodie aside. His cock pressed insistently against her ribs, throbbing in time with his heartbeat.

In front of her, Jake began to reach out, then hesitated.

"...Can I touch you?" He asked.

Seeing him frozen like that, trembling with need, put a strange shiver of delight through Sarah. For the first time she felt grounded, slightly more in control of the situation.

"What are you gonna do?" She asked.

"Help you with your heat." Jake grunted. He managed, despite everything, to sound genuinely charitable. Sarah kept glancing between the coyote's legs, to where pre gleamed from the pointed tip of his cock. He wasn't as big as Aiden, but his knot looked so deliciously thick...

Sarah blinked hard.

"If I say yes, you have to promise always to be nice to me no matter what." She said.

"Done." Jake agreed in an instant.

"And apologize for putting gum in my fur."

"You're still...?" Jake began to protest, then caught himself. He drew up straight and managed an expression of sincerest contrition. "I am deeply sorry, Sarah. Won't ever happen again."

Though someone in a clearer state of mind might have found room for doubt in the authenticity of the coyote's words, Sarah hardly minded. To see her brother's no good friend practically prostrating himself before her was reward enough. Slowly, she allowed her legs to fall open, leaning further back against Aiden. His paws came around and interlinked just beneath her breasts.

Sarah let Jake strip her panties off, exposing the slick ebony folds of her pussy. The coyote let out a slow, shivery breath, paws sliding slowly down the insides of her thighs. Sarah shivered and could not contain a giggle.

"What are you...?" She began to ask, then the coyote pushed his muzzle between her legs. For an instant there was cold, his nose poking at her clit, then came the warm, eager press of a flat canine tongue. He spread the lips of her sex and took a deep breath, inhaling her heated scent. His tail wagged even faster.

Sarah couldn't have contained a moan if she'd tried. She flopped back against Aiden, legs twitching and tail swishing jaggedly from side to side. A flood of surprised words bubbled up and she flashed a startled glance at Aiden, but before anything could be said her brother leaned down and suddenly their lips met. She gasped, mouth falling open. Their teeth clanked for an awkward moment, then Aiden found an easier position and kissed her again, more fully. His paws came up to squeeze her breasts, fingers finding the tingly peaks of her stiff black nipples.

"Aiden..." Sarah managed, filling the instant between one kiss and the next. The whole world was overflowing, it felt like. She hardly knew what could possibly be said, there was no room for words between the busy tongue between her legs and now the wonderful wet heat of her first kiss. That it was with her brother...

Somehow, she couldn't entertain even the slightest shame. All that registered was a sense of ecstatic taboo, there and then gone again. More noises were rising from within her, moans and needy little whines wrung from between her lips by the talented canine tongue working away at her wet little slit.

Everything she'd used to pleasure herself before; fingers, vibrators and shower nozzles, seemed pale and immaterial in comparison to the attentions of another person. Though a part of her didn't want to acknowledge it, the coyote clearly knew what he was doing. Or perhaps canines were just good at licking.

Slowly, she sagged further down onto the sofa. Everything within her felt as though it had been wound far too tight, yet somehow she could not move at all. High, desperate gasps sounded with each new exhalation. Jake flashed her an amused grin for just a moment, then was suddenly rubbing a pair of wetted fingers over her clit, the move smooth and practiced. It felt as though some sort of slow, all consuming electrical shock were building to consume her.

"Ff...Ggh..." Sarah could only attempt words through gritted teeth, then she was swept over the edge, the corners of her vision filled with a dazzle of rainbow spots and every bit of her locked ecstatically tight. Her mouth fell silently open and she felt her tail trembling where it had shot out perfectly straight. Jake continued to work her, not letting up for even a moment. The coyote's expression had returned to smug slyness, enjoying every bit of her incapacitation.

"You good?" He asked after a few more moments of wonderful torture, casual as anything. Sarah didn't even attempt to respond. She lay perfectly still, gasping for breath, legs shivering. For an instant the lust cleared from her mind and was replaced with a sunny feeling of euphoric wellbeing...but this only lasted for a few seconds, then the need was back. A part of her felt almost annoyed, the rest burned with mingled curiosity and lust at the idea of what might be coming next.

Sarah gave Jake a shivery thumb's up, then looked to Aiden. She hadn't quite realized it at the moment, but she was lying practically flat now, her head in his lap. Aiden took her beneath the arms and pulled her closer, one paw rising to stroke her fondly behind one ear. Sarah thought that perhaps he might lean down to kiss her again, but she was left as she was, eyes perfectly level with the eager throb of his cock. It was all too easy to sag forward and bury her nose into the warm puff of fur where his sheath met the low hanging swell of his heavy balls. Sarah took a shivery breath, enjoying how Aiden's paw came to stroke along the side of her face.

"Ready?" He asked.

Sarah glanced quickly back to where Jake had positioned himself between her legs, the heated girth of his cock rubbing impatiently against one thigh. A small part of her wondered if it was really right, letting the no good coyote be the first one to have her, but even trying to think about this in the heat of the moment felt useless. What sort of meaning really was there? Sarah spread her legs and twisted her upper body so she could more fully face Aiden. It was sometimes useful to be a mink, stretchier and more flexible than most other species.

"Ready." She said, doing her best to sound it.

Jake acted first, the tip of his cock pressing insistently against the sensitive folds of her sex as he lined himself up. Then, slowly, he pushed into her. Sarah forced herself to relax, even as her legs once again trembled and a heated pulse of tingly delight tightened each one of the tiny muscles governing the silken heat of her near-virgin snatch.

"Oh fuck..." Jake groaned, ears pinned back. He was panting already, tail still triumphantly wagging.

Sarah felt herself shoved forward by the weight of the coyote's first thrust, not hard but certainly thorough. She let herself go with it, muzzle pressed up against the base of Aiden's cock. He let out a shivery little breath, then guided her mouth along his shaft. Sarah licked, the taste of salt and iron blooming across her tongue, mingled with an unidentifiable other taste that she supposed had to be unique to her brother.

It felt intimate, impossibly special to be so close, sharing such a moment and making him feel good in the same way that he was doing with her. She braced one paw against the inside of her brother's left thigh, then dared reach in and weigh his balls with the other. They were big enough that she could hardly fit her fingers around them, heavy and firm. Aiden's cock twitched and Sarah caught a spurt of pre across one cheek. Then she was at his tip. Sarah opened wide and allowed her muzzle to be filled. It was shockingly easy to hilt him into her; Sarah had never given much thought to the active mechanics of giving a blowjob, but it probably helped that she belonged to a very adaptable species. Certainly one used to swallowing a great deal of meat.

She looked up, to where Aiden had leaned back against the arm of the sofa. He was breathing hard, whiskers twitching and eyes wide. He looked halfway surprised, yet also deeply pleased, a simple adoration warming his expression. Something about it reached within her and Sarah felt warm as well, not in a perniciously lustful way, just...warm.

Between her legs, Sarah felt the swell of Jake's knot press at her entrance, the coyote testing to see just how far he could push into her. For how small she was, it didn't hurt to accommodate his girth. All Sarah felt was a pleasant feeling of fullness, traced all around by the same halfway electrical tingling that had forecast her first climax.

The coyote kept up a steady rhythm, but Sarah could feel a mad lust threatening to undo his restraint; the heat and wet grip of her cunt calling for him to rut her just as rough and wild as his feral ancestors might have done. It both exhilarated and frightened her (though only a little).

"Fuck..." Jake groaned again, ears pinned tightly back. He was gritting his teeth, fighting hard not to go over the edge. Already Sarah could feel his cock throbbing desperately inside of her. His grip on her thighs tightened, almost enough to hurt.

Sarah pushed back against him, legs tight against his hips. At the height of his next thrust the coyote lingered for a long moment, putting his full weight into trying to push the swollen girth of his knot into her cunt. Sarah whined and bucked her hips, a white hot sparkle of pleasure rippling through her center. She could feel a tight band of resistance slowly giving way, a thousand tiny muscles still molded perfectly around the girth of Jake's cock, tight as a velvet lined trap.

She moaned unapologetically around Aiden's cock, possessed once more by a full body shiver, then felt him sink fully into her, his hips meeting hers. A dozen fragments from a dozen erotic stories and porn videos flashed nonsensically through Sarah's mind, but there was nothing in them that could compare to the real thing. She squirmed and cried out, legs locking tight around Jake's hips. For an insta the coyote looked surprised, then smug, then his teeth were gritted tight and his eyes squeezed shut. He leaned over her, still desperately forcing his cock deeper into her with messy bucks of his hips, then Sarah felt his heavy balls tighten against the base of her tail and the coyote let out a very canine whine.

A hot bloom of liquid warmth soaked her pussy and overflowed her womb. Sarah whimpered and moaned, the world once more falling away. She clung desperately to Aiden, tongue playing across his cock. He looked down at her, still aglow with a shivery delight.

"Sarah..." He managed, then his hips jerked and whatever he'd been about to say dissolved into a gasp and a moan. A thick, sticky pulse of musky seed landed upon her tongue, then the next splashed her mouth and in a moment she was drenched in her brother's cum. What she'd caught in her mouth tasted both creamy and slightly bitter. Sarah swallowed almost before she could think about it, producing an audible gulp. Aiden stared at her, a shiver of lust upsetting his fur. Silently, he put a gentle grip on one ear and guided her mouth back to his cock. Sarah obediently cleaned him, enjoying the little noises he made each time her tongue roved somewhere especially sensitive.

At last he flopped back and Sarah was released. She flopped against Aiden's stomach, watching with a hint of sadness as his cock slowly shrank back into its sheath. For a moment the room was silent but for the sound of heavy panting, everyone struggling to get their breathing back under control.

Sarah looked down, to where Jake had collapsed across her, face nuzzled pleasantly between her breasts. He surveyed her cum spattered face and smirked. Within her, Sarah could feel his knot throbbing, still unloading tiny spurts of canine seed into her overloaded pussy.

"I can't believe you took the whole thing," he said with genuine astonishment. "If you ever wanna do it again, just you and me..."

"Jake..." Aiden said tiredly.

"Sorry," the coyote said, raising a placative paw. "But...I mean, you did just cum on your sister's face."

For a moment there was a deeply, intensely awkward silence. Sarah squirmed in place, feeling slightly trapped. Now that she'd gotten her breath back, she was again beginning to feel the need returning. Not quite as intensely, but it was still definitely there.

"How long does your knot last?" She asked, breaking the silence.

The coyote straightened up and tugged experimentally at his knot. Sarah just barely managed to suppress a moan, but there was no disguising the way she immediately clenched down on Jake's knot.

"Not too long. Twenty or thirty minutes." He said, wearing the edges of a self satisfied smirk.

As it turned out, the coyote was soft enough for her to pull free after a little more than fifteen. Aiden fetched a towel and pushed it under Sarah's hips, so that his couch wouldn't be drenched.

"Ready?" Jake asked. Sarah nodded, as bravely as she could, then made herself relax. A huge pressure built, then Jake pulled back and his knot slipped out of her with a wet pop and a flood of warm coyote seed. Sarah fell back, legs trembling and her breath coming in shaky little gasps. Jake stood and stretched, looking very happy.

"I don't think I can stand..." Sarah said, giving her brother a slightly guilty look. Once more she was thinking about the stairs. The idea of having to crawl up them was distinctly unappealing. But, even as she pondered, Aiden simply leaned in and picked her up. Sarah felt her heart flutter and couldn't contain a tiny, halfway startled giggle. She wrapped her arms around her brother's neck.

"Um, I should get going now..." Jake said. The coyote had put his pants back on and, but for the general dishevelment of his fur, looked perfectly ordinary, as though nothing had happened whatsoever. Sarah couldn't keep her eyes from straying to his groin. Her pussy still tingled though, somehow, she didn't feel the slightest bit sore. Heat was a hell of a thing.

"Alright," Aiden said. "I guess I'll talk to you later. Tonight, maybe. And Jake..."

"I won't tell anybody," the coyote said, gently preempting his friend. "Lips are sealed. I swear." He mimed locked his mouth and throwing up the key. Sarah, though she'd not had much time to seriously contemplate the aftermath of...whatever had just happened, still felt relieved. While Jake could certainly be a bit of perv and a pill, he wasn't a gossiper.

Aiden bid the coyote farewell, then carried her all the way up to her room. Sarah felt momentarily embarrassed looking at the clutter crowding her bedroom, then figured that it couldn't possibly be more out of the ordinary than what she'd done downstairs.

"Are you alright to stand?" Aiden asked.

Sarah nodded and willed her legs to stop trembling as she was set down. She could remain upright, just about, though her tail would not stop swishing in odd directions.

"Um...thank you." Sarah said, unable to meet Aiden's gaze. Already she was tingly and heat addled again, every bit of her filled with the same dull, irritating need.

"Aiden?" She asked.

"Yeah?" He asked. Sarah noted, with a sickly sinking feeling, that her brother couldn't quite meet her gaze.

"We're...still okay, aren't we?" She asked.

At this Aiden blinked, looking at once surprised and slightly guilty (though for what Sarah couldn't imagine). He nodded quickly.

"Of course we are," he said, then glanced behind her to the adjoining bathroom. "We should get washed off, yeah?"

Sarah supposed that was a good idea. The mess on her face had become unpleasantly gummy and cold.

Aiden came with her into the bathroom. It was a little space, with a toilet, a sink and then a relatively little shower. Sarah turned it on, testing the temperature with one paw as she watched her brother.

"Are we showering together?" She asked.

"Saves water, right?" Aiden asked, a bit sheepishly. Sarah wanted to hug him...but figured that this could wait until after she'd washed off her face.

Despite how heat addled she felt, and despite the fact that she was showering with her own brother, for a long moment they simply stood and let the water wash over them. Sarah scrubbed her face and then gingerly probed between her legs, though the whole space was so sensitive that she could barely touch her pussy without shivering. None of it felt unpleasant, exactly, but there was still that same odd electric shock feeling.

Watching her efforts, Aiden managed a half smile.

"Want me to take care of it?" He asked.

Sarah hesitated, feeling halfway surprised, then guiltily nodded. Aiden took the shower nozzle and guided her into a sitting position on the floor (so she wouldn't topple over, Sarah supposed). Then, very precisely and with zero mercy, he sprayed her clean. Sarah tried not to moan, kick or cry out, but it was very difficult to mute even the tiniest of her reactions. By the time he was finished she'd been reduced to a twitching puddle, tiny gasps leaking from between her lips.

"Are you okay?" Aiden asked. His concern was slightly undercut by the tip of his cock poking free of its thick, fuzzy sheath. Sarah managed to sit up, still trembling, then sagged forward into her brother's legs. Every atom of her being demanded that she open her mouth or spread her legs, anything to invite another pounding.

"God, I'm a mess..." She mumbled.

"You're in heat. It's normal." He hesitated, then helped her up. "And, I kinda lost my head too. Downstairs...I kissed you."

"That was my first." She said quietly.

Aiden blinked.

"What about that kid in seventh grade? You bragged for a week."

Sarah couldn't tell if her brother looked more surprised or amused.

"I lied." She admitted.

"So..."

"It was nice," Sarah said. "Even past the heat, I liked it."

Aiden let out a slow breath. He said nothing but his gaze had gone very direct. Flutters of warmth and want filled Sarah and made her feel as though she were floating.

"Do you want to do it again?" She asked.

He kissed her.

By the time they stepped from the shower Sarah felt giddy and warm. They had stuck to kissing, no matter the temptation to go further. There simply wasn't a lot of room to fool around in the shower, though that hadn't stopped Aiden's paws from wandering. The memory of his touch tingled upon her breasts and hips, between her legs and behind her ears...

"You know all about me, so...what have you been doing at school?" Sarah asked as she dried her fur. The question came shakily, her heart was beating too fast for anything to feel especially steady.

"What have I been doing?"

Sarah felt the insides of her ears go pink.

"Sex." She clarified, feeling a bit foolish. "...What do you like to do?"

Aiden smiled permissively, then scooped her into his arms. Sarah squealed and laughed.

"I love that you're little enough for me to do that," he said, then nudged the bathroom door open and brought her back into the bedroom. "Now let's see, what kind of treatment does my darling little sister deserve..."

He placed her down on the bed, the silky satin bedspread shushing beneath her, striking tiny prickles of static from her fur. Sarah let out a slow, anticipatory breath as Aiden slid smoothly over her. He was achingly hard, fat beads of pre gleaming at the head of his tapered shaft.

Sarah tried to say something but he kissed her silent, his tongue pushing firmly into her mouth, pinning hers without the slightest effort. This felt different than down in his bedroom; that had been a surprise, impromptu and very much improvised. Here, he was fully in control. Sarah let out a slow breath, feeling dizzy with lust, as though she might swoon away at any moment.

He moved between her hips and Sarah felt a slick heat slide playfully across the still sensitive folds of her snatch, Aiden taking his time to line himself up. He broke the kiss and watched her pant helplessly, puddled out across her own bedspread.

"I missed you." He said, then pushed forward and claimed her.

Aiden moved quickly, hilting himself into her with a pair of hard, dominant thrusts. His weight was huge and immediate, pinning her to the bed, taking the edges from her breath. Sarah gasped, the noise threaded through with a desperate moan. She felt dazzled, utterly overwhelmed in the best possible way.

Adoring words bubbled up, but with each attempt to air them they turned to little squeaks and moans. She grabbed hard to Aiden's wrists and wrapped her legs tight around his hips, mouth open rapturously wide except for when he sealed with with deep, perfect kisses.

Within her, Sarah felt splashes of pre soak her cunt, further easing the way for Aiden's cock. It was almost uncanny how perfectly he fit her, just big enough to make her gasp, but not so thick or long that there was any pain. Indeed, she felt a strange pride in how well she was playing her part; meeting his every thrust with mews and moans of delight, massaging his cock with the silken heat of her eager sex.

At last a few perfect words managed to form and launch from her tongue, as though guided by divine purpose.

"I love you." She gasped.

He kissed her, something different about the gesture now, gentler and yet more deeply pressing. A shiver of ecstatic delight passed through him, drawing everything taut, and Sarah felt her brother's cock twitch and then flood her with a dozen fast, heavy spurts of seed. She clutched him tight, helpless little twitches and euphoric moans wracking her well fucked self.

Rivulets of cum began to pool at the base of her tail, but Sarah hardly minded. She took a deep breath, trying hard to recover herself. Aiden idly stroked her left ear, enjoying how he made it flutter.

"How was that?" He asked.

Sarah just smiled and kissed him on the tip of the nose. It was perhaps a bit early to tell, but she thought that maybe, just maybe, her heat had entirely gone away.
