She felt warmth suddenly shooting up inside her vagina.  He'd taken advantage of her while she was sleeping, and now he was ejaculating in a hot flood, dumping his seed where it belonged.  Katie whimpered at the very notion, curling her toes as her brother continued his morning delivery with squirt after trembling squirt.  He kissed her cheek, squeezing her with his paws, grunting and huffing as his penis did its thing.  She laid there and just enjoyed it, listening to his laboured breaths, safe in his embrace, gently tingling as sleep receded from her body.  His penis felt a little bigger in the mornings, harder; morning wood was a great name for it.
 
Tommy kissed her again, this time on the side of her mouth; she blushed lightly and turned her head.  As her brother's squirts slowed, their muzzles joined, and he gripped her a little tighter.  Oozing.  Twitching.  Warm.  Stiff.  They kissed; she squirmed; it started leaking down her legs. First a trickle, then a flood: the sheets were ruined again.
 
*******
 
The fabric darkened, getting wetter and wetter; soon it was saturated and glossy.  With a jerk the wetness started sloshing inside, roiling and churning as it was driven by the ceaseless rhythmic agitation.  Tommy pulled his head away from the glass window at the front of the washing machine, nodding in satisfaction at the progress.  He giggled nervously, glancing over to where Katie sat atop the dryer.  She'd dared him to put all the clothes he was wearing in the wash as well.  He'd dared her back; now both cubs were naked.

"Umm...  So what do we do now?"

Katie tutted and shook her head, as if this were the most obvious thing in the world. "Well...  We either stay down here and play games till it finishes, or we can try making it up to our rooms without getting caught."  Her eyes widened in mock horror, and then she gave a sly grin. "If you ask me, we're much better staying put..."

Tommy nodded with a grave expression, but then his eyes grew wide. "But what if they find us in here!"

She shook her head again, looking quite disappointed. "Sheesh, would you relax?  They're watching their film together upstairs; it's gonna be *hours*.  And if there's a problem..."  Katie turned and yanked a folded white bed sheet from behind her, unfurling it with a shake of her paws.  In a dramatic sweep she swung it around her shoulders and let it settle. "You wanna play ghosts, Tommy?  Ancient Greeks in togas?"  She giggled and he smiled a little, watching her.  A little flutter of excitement arose in her chest; things were getting risky lately, yet she wanted it.
 
The room was spartan, yet quite cozy; its plain white walls were only broken by a single small window.  A modern washing machine held court on one side of the room, nearest the window, more buttons and glass than a car.  Across the other side was the tumble dryer, a simpler affair but modern too.  A few shelves adorned the walls, covered in bottles of cleaning products, packets of washing powder, all the accoutrements of a clean home.  The smell was not unpleasant; a harmony of soft chemicals and softer sheets permeated the air.  Baskets of those same sheets, neatly folded, were stacked behind Katie and waiting to go upstairs.

Tommy looked at his sister, facing her with his naked bum just brushing the cold metal of the washer.  She was soft too; that soft smile played across his lips at the way she made him feel.  The sheet hung loosely and didn't obstruct his view, of her, of her soft breast and tummy, of her soft thighs, of her softness in between.  He gave a little shiver and squirmed where he stood against the washer; it thrummed against his legs.  She was smiling even wider.  Looking.  Looking at his...  He gasped and blushed deeply, covering himself with his paws, trying to hide his tip peeking out.
 
"Awww...  You got a different game in mind, huh Tommy?"  She tried not to tease, but it was so difficult, so irresistible; he was terribly cute when he got like this.  "Come over here.  Come on, please Tommy, I won't bite."  She put on her best smile.
 
He continued blushing, trusting himself to glance only at her feet; his squirmy feelings weren't going anywhere.  But then between those feet was that sleek tail that went up, up, up to her...  Her sleek legs, spotted and smooth furred, everything just led his eye straight to...  Tommy gave a little whimper and pushed off from the machine.  Hesitantly he approached, making a show of hiding himself, but his heart just wasn't in it.  She sat on the corner of the dryer, legs hanging down either side, naked but for the bed sheet round her shoulders.  Tommy stood in front of her and looked up; she had an even greater height advantage than usual on him.
 
Katie put her paws on his shoulders, smiled, and then pulled him into a naked hug.  The sheet found its way around both of them, enveloping, cocooning; Tommy found his head against her tummy.  He put his arms round her back and held her, smiling again.  Soft.  Round.  Warm.  Tommy kissed it, and she giggled.
 
"Hey...  What was that fo..."
 
The cub kissed her soft round tummy again.  Her scent, her soft girl smell filled his nostrils and he gave a happy sigh.  Lower, and another kiss, Tommy found himself in a sensual rhythm, planting those soft brother kisses again and again now, all the way down her tummy.  She /was/ putting on a little weight, wasn't she?  He didn't care; she shivered; he could see her clenching her teeth in soft pleasure.  He could see without looking; he knew her; he knew her sounds; he knew her smell.  Her girl smell.  Tommy licked his lips and brushed them below, below her tummy; a sharp intake from Katie whistled through her teeth.
 
Lower, her scent was strong now, sweet and naughty; he felt her legs parting as the kisses rained down.  Delicate skin, delicate fur, private and warm.  Delicate kisses, delicate folds, Katie let out a whimper and held his head through the sheet.  Tommy's nostrils flared, and he kissed, kissed her lips, kissed his sweet sister between the legs; her paws slipped.  She gasped and he reached under her thighs to push, push them up, push them back.  Katie lost her grip on the sheet as she reached behind to steady herself; it slipped off both of them, twirled to the ground, forgotten.  Tommy was beginning to pant; he kissed once more; he kissed her vagina, wet lips and then wet tongue.
 
She squirmed and her taste begun to flow as he licked at her, her private spot, first a touch and then...  Katie gurgled as his tongue swirled under her tail and then up her slit, higher, higher, and then the same all over again.  Tommy grunted, determined, hungry, thirsty for her as her naughty flavour flooded his mouth.  So soft, so delicate, so yielding, he couldn't stop, wanting to feel every inch of her, wanting her to feel.  Every part, it didn't matter; it was all hers and it was his treasure.  Under her tail, that smooth tightness, her other hole.  Curiosity piqued, the leopard licked again, again, smelled her gentle musk, felt her moan, nothing but sweetness to him.  He'd never taken the time to think, to wonder, and now his tongue lapped, flicked at that delicate skin; she made noises she'd never made before.
 
But her sweeter scent called to him, like honey; it pulled his nose higher, higher, and he licked.  Katie mewled, nearly slipped, as Tommy's tongue dragged up her slit.  He was slipping in between her folds; they both shuddered as he licked again, sweetness flooding his mouth.  So soft.  So wet.  Her wetness, and now his.  He pressed.  Tommy spread his sister's legs wider, and he pressed his wet tongue against her.  Her soft lips began to part, and inevitably, inexorably, the boy's tongue began to slip into her.  She mewled again, and he pressed.  There was no stopping it, no stopping them, as it found entrance; slippery wriggling wet warmth penetrating her vagina.
 
He was inside her, deeper and deeper, it came easy now.  She whined, softly pulled his ears, and then he threaded his tongue the rest of the way in.  Muzzle pushed hard between her legs, her taste in sweet floods, so warm, tight, slippery.  Her thighs brushed his cheeks and his tongue curled, curled inside her; he flexed it and she cried out.  Wriggles, devastating wriggles of his versatile pink flesh; his sister trembled, squirming and squeezing; he could feel it on his tongue.  Tommy gripped her thighs a little tighter and pushed them further, tilting her, exposing her full femininity to his assault.  He pushed, soft nose brushing her special spot, licking her deepest parts; Katie began to chirp.
 
Utterly helpless, the girl succumbed to a squeezing eruption of pleasure between her legs.  Tommy felt sudden spasms rippling along his tongue; he blushed; he'd just pushed his sister into her sweet release.  Carefully, it was a little too much to endure, he pulled his tongue free, feeling the soft flow of her fluids increase as she writhed.  That taste too, it never left him and he gently licked at her, hearing her mewl louder and hold his head.

There was a sudden thump-thump-thump that made both of them gasp out loud.  Someone was coming downstairs!  Tommy pulled back and they stared at each other in panic.  Katie couldn't stop, couldn't stop huffing, panting, gasping; she put her paws between legs as if they could stop the flow of pleasure.  There wasn't time; Tommy stared a while longer and then started wiping at his muzzle with both paws.  Wet with his sister's fluids.  A few seconds later he crouched down, picked up the forgotten sheet and threw it over Katie.  Finally, heart racing, he plucked a sheet for himself out of the basket, whirled it over himself, spun around...

"You two had better be folding those, and certainly not playing in them; I spent hours ironing last night."

Tommy gasped and poked his head out one end of the sheet, being sure to preserve his modesty, which was rather stiff right now. "Y-yes mum!  We'll fold them all up nicely won't we Katie?"  He glanced up to see her struggling under the sheet. "We're doing all our own washing to save you the trouble, see?"  Tommy gave a cheesy grin.

Mum rolled her eyes but then nodded; perhaps they'd save her more time than they'd cost. "Fine, but /please/ put everything away when you're finished."  Seemingly in a hurry, the older leopard retrieved a bottle of cleaning spray and a sponge.  Without another word she turned and left.  Another thump-thump-thump and she was gone upstairs.

Tommy's sheet dropped to the ground, heart racing.  He looked at Katie, still struggling, tangled in soft white.  That roaring in his ears, the flutter in his chest, it had been so close and yet...  Tommy was excited.  With a soft pull he freed her, exposed her, lent her naked body to his eyes.  The boy came back between her legs, set them on his shoulders and snaked his paws behind her bottom.  Her eyes widened and she looked down as Tommy picked her up with a grunt.  Struggling, he gently carried her across the room; she briefly held him around the neck and then he placed her down on the washer. 

Tommy looked at his sister.  His penis throbbed.  She was wet between the legs: slippery, pink, warm.  She looked back at him, panting, unsure of what just happened.  The washer jerked suddenly and began winding up to the long spin cycle; Katie gasped.  Tommy licked his lips; it was time.  Her eyes widened as he gently nudged her back further on top of the machine, then clambered up too.  Breathing deeply and with an intensity she'd not seen before, he lent her back and held her with his paws as he laid on top of her.  Both their legs hung off the side and his erection made itself felt, smooth firm and warm between them.  She shivered, shivered again as the washing machine began shaking and pulsating wildly.

Tommy's muzzle dipped in for a kiss, wet with her scent.  He kissed his twin and with a gasp, found her warm crease, pushed, drove his stiff willy all the way inside.  The whole world was vibrating, every bone, every muscle; it strummed as if alive.  He held her, held the kiss, twitched inside.  They could hardly breath, pressed together while the spin cycle roared.  He could hardly move, but wanted to.  With a grunt, Tommy began to mate his sister, trembling with overloaded feelings.  He broke the kiss and laid his muzzle on her shoulder, thrusting, deep and slow.  She squeezed on him, squirming, breathless, wet, squeezed again; he groaned.

His tail rose up and she called his name, softly, desperately, begging for his release.  Soft balls brushing the vibrating metal, the cub cried out, pulled Katie against him and sank all the way into her.  His tail flagged, jerking up and down; the cub shuddered and started squirting her full of his seed.  She cried out too and began squeezing on him, milking his length as it put more and more of his warm sperm inside her.  Their nerves were on fire as the machine quivered and shook, driving their twin pleasure ever higher.  Tommy moaned and fired jet after jet, ears flat to his head, tail in a delicate dance behind him.  He could feel her filling with his ejaculation; it pooled and flowed more and more in her deepest recesses.  Tommy clung to her and shivered all over as deep pleasure rippled through them both.  

He arched his back and moaned again, finally starting to run dry, but the rush of feelings from his stiff willy were somehow intensifying.  Gripping his sister even tighter he gasped, shivering, trembling, fighting for breath.  He...  He couldn't be.  He couldn't...  Tommy cried out louder and began ejaculating anew, the second time in a minute, squirting hard.  His tail flagged faster as he dumped even more cub seed inside her, mewling, out of control.  Katie mewled too, gasping at the renewed wet torrent inside her; would it ever end?  She shivered, tipped her head back and joined her brother in a second release.  Her vagina squeezed hard, really hard; the cubs could barely stand it.  Endless pleasure washed through both of them, relentless as the thrumming spin cycle.  The soft drip-drip-drip of semen indicated Katie was once again filled up.  It oozed from her in soft bursts each time Tommy spurted inside; one in one out, there was no way she could hold it.

The spin began finally to wind down, the machine shaking violently a few times; the cubs gasped and clung to each other.  Tommy squirted as many times as he could, but finally, mercifully, he was finished.  In a pleasured daze, he couldn't quite believe what had happened, but the sticky flood that was starting to leak down both their legs told the story.  Shivers telegraphed between them, one setting off the other; he murmured and looked up at her face.  She looked back, half smiling in her own little world, a muzzle lit up with gently fading pleasure.  Tommy kissed her and then shivered; the metal was cold, now still beneath them, uncomfortable.  Katie gasped as he pulled away, first muzzle then groin, and planted a gentle kiss on her furred chest.  He slipped out with a wet sound and then carefully clambered backwards down to the laundry room floor.

Standing in front of the machine now, in front of her, he looked at Katie again with soft love.  First muzzle then groin, he could see how thoroughly he'd mated her.  Tommy's penis twitched as he stared at her matted fur, at the slickness, at that gap between her legs which oozed his wet essence.  He leaned forward and she watched as he placed another kiss on her round tummy.  With no preamble this time, Tommy dipped his muzzle between his sister's legs and began to lick; she mewled.  Salty sperm flooded his mouth and his willy twitched harder; he had to lap it up, every drop.
 
It was some time before the twins made it out of the laundry room.
 
*******
 
Night time, she stirred from a deep sleep.  He was sleeping with her again.  They were gonna get caught if this kept up, no doubt about it.  But the leopard gasped and softly whimpered in pleasure as she felt his stiff willy nudge her, then push all the way inside.  Inside her tight vagina.  Katie bit her lip and squeezed on him, felt his paws excitedly brush her sides, felt his quick breath against her neck.  Side by side, as always, as ever; he liked it and she did too.  And he needed her.  It wouldn't wait till morning, wouldn't even wait another second; he needed her and so he was mating her there and then.
 
Katie shivered deeply and curled her toes, squeezing on him again; he moaned softly in her ear.  He needed her.  Another shiver and she moaned with him, unstoppable pleasure unexpectedly flooding through her.  He wanted her, and so he'd just put his willy up her, simple as that.  She mewled, trembled, pushed back against him as her vagina began to spasm.  His soft noises in her ear grew louder.  Katie gasped again and again and again, each one a helpless squeeze; it was too much; it was just... 
 
She gasped loudly as a sudden burst of delicious warmth sprayed wetly against her vaginal walls.  It was followed immediately by another, and then a third, and Katie shook as her brother set about filling her with hot sperm.  He was ejaculating in her.  So much, so soon, and it was because of her.  Katie felt the warmth spreading and began to thrash, great spasms wracking her body as the pleasure suddenly redoubled and burst inside her.  Trembling paws gripped her, held her as they poured seminal fluid into her fire.  Strange mewling sounds escaped her lips as she accepted her brother's wet gift, sanity slipped away as feelings became nearly unbearable.
 
Katie pushed her paws between her legs and shook, bearing down on him fiercely; he groaned hard and squirted harder.  She couldn't stop it, she just couldn't, she...  Her paws touched his penis and that's when she started losing count.  As soon as one orgasm begun to fade, the next suddenly exploded, like a string of Chinese firecrackers.  Colour drained out of the world as she gasped and hitched, trying to breath, trying to surf her own waves but drowning.  With a sudden intake of breath, Katie fainted.
 
Tommy noisily finished filling her up, breeding her now mute, limp body as she gently spasmed in his grasp.  His strained face held a look of slight puzzlement, but as his own nocturnal emission came to an end, fatigue quickly swept in.  Within minutes he was asleep with his arms round Katie, stiff penis still buried inside, an erection that persisted for some time.  Katie's dead faint became sleep, and the cubs slept together.  

*******
 
"I said what's got into you lately, Tommy?"  Katie smiled at her brother patiently.
 
Tommy stared fiercely at the screen. "Hmm?  Oh...  I don't know, really," he mumbled distractedly.
 
Katie rolled her eyes and scooted around so she was nearly in front of him, trying to catch his eye. "There's something different about you..."
 
He stared right past her, never breaking eye contact from the fierce adventure playing out on the screen as he wielded the games controller. "Oh...  Is there?"
 
"Tommy!"
 
He jumped, nearly dropping the sleek white plastic from his paws. "What?!  Damn, gonna die...  Nope, got it!"  Tommy chewed his lip, already engrossed again.
 
The girl blew out a long sigh between her lips, dropping her head down in defeat.  He was so difficult to get through to sometimes.  After a moment, Katie lifted her head up again, eyes sparking suddenly with mischief. "I guess I'll just have to show you how you've been..."  She rocked forward onto her knees and came a little closer, the back of her frilly skirt just brushing the ground.  "It's like...  You're more... Confident."  She placed one paw on his knee and he flashed her the briefest of glances before focusing all his attention back on the large display.  "You've started...  Doing naughty things to me."  The paw slipped down his thigh, down, down to the crotch of his shorts.
 
Tommy gasped and spared a slightly longer glance, but he was determined not to loose this level. "Katie..."
 
She nodded, fumbling at his top button before undoing it, now crouching at his side. "Started doing naughty things to me...  Without me encouraging you."  The leopard found his zip and gently tugged it down, undoing his shorts all of the way, feeling her brother give a very soft shiver.  "I'm not complaining, of course."  Without any further delay she slipped a paw down the front of his undies, grinning slyly as she felt an already hardening sheath.
 
He nearly dropped the controller, chewing his lip for a different reason as a soft whimper escaped. "Oh..."
 
"But it's not exactly like you, Tommy."  She cupped him, cupped his smooth furred balls in her paw, so warm, plump, firm, full of what she craved.  Another whimper.  "I wonder what happened?"  The shorts had to go.  She pulled her paw back, carefully, and started to tug them down, a most terrible distraction.  Tommy grumbled and rolled his eyes, trying desperately to play his game, yet willfully complying as she slipped his shorts and undies under his rump and then off.  Anything to make her stop.  "You know, it'd be more fun if you always played with your Wii like this."  She barely suppressed a titter.  He rolled his eyes again, now in just a t-shirt.
 
Katie got onto her knees again beside him, looking her brother up and down seriously. "So what's it going to be next time, Tommy?  Do I see the old Tommy or the new?"  Her paw found its way between his legs again, making him gasp, making him red.  "Will you just mate your sister whenever the desire strikes?"  Tommy whimpered as she pulled her paw back and then straddled him, still vainly trying to look around her and play his video game.  "Just lift my skirt and go to town?"  Katie squatted lower and lower, her skirt settling over both of them; she was coming down directly into his lap.  He gave a little grunt; Katie bit her lip as his stiff tip brushed her and then twitched.  She wasn't wearing any underwear.  Again.
 
"What do you say huh, Tommy?"  There was some adjustment to be made; she settled her paws on his shoulders and gave a wry smile as his head still tilted, still trying to see.  She was very close now, almost leaning against her brother while she tilted her pelvis and made it so... easy. Tommy gasped at how he just slid up into his sister; the game controller clattered to the ground, forgotten.  She sunk all the way down, slowly, savoured every nuance of the experience.  His beautiful, tapered tip, such a perfect point that invaded, spread her vagina gently wider and wider with its stiffness, lent her warmth from its heat.  "Oh...   Mmm...  And night times don't count." 
 
As it sunk deeper, deeper, she was already anticipating what would inevitably spurt from that very tip: his rich and sticky semen she'd never grown tired of.  It completed her, filled her, every crevice, every nook and cranny drenched in his essence.  But that was to look forward to; now she felt the familiar tickle as Tommy's sheath touched her, and then was pushed all the way down to his base.  Katie heard him let out the breath he'd been holding as their bodies came together; she sat, and he was all the way inside her.
 
Tommy looked at the door suddenly, didn't turn back.  Katie followed his gaze...  A burst of fear and excitement gripped her.  The bedroom door was wide open!  Mum and Dad were just downstairs, in the kitchen it sounded like; dinner wouldn't be long.  Yet a new feeling arose, maybe a dangerous feeling, but then it wasn't really new, was it?  Katie looked back at her brother; his face mirrored hers; he turned back from the door and met her gaze with worried eyes.
 
"Sis..." he began, but she put her fingers to his lips, smiling a naughty smile.  Tommy didn't like the look of that smile at all and squirmed, making his sister give a little grunt.  He felt it too, and his heart was racing again.  They could get caught.

Katie nodded, "Shh... Let's talk later, see how quiet we can be now..." 

Tommy grimaced, shifting a bit more, but this seemed to make Katie more determined; she slipped a hand down to his crotch.  The other one remained on his lips and she winked, easing up off him a little and then rubbing at their connection.  The effect was immediate and it was as if his eyelids had suddenly grown heavy, the boy groaning as softly as he could.
 
"Tommy, Katie, dinner time! Wash your paws and come down now please!"  The voice echoed up the stairs and their gazes locked, eyes wide with fear, pleasure, excitement.
 
With great effort, Katie found her voice, always Katie. "J-just coming!"  That paw moved off their connection and came around behind them, under her tail, until she brushed his soft balls.  With a smile from her and a gasp from him, she squeezed, rubbing them, rubbing at his muzzle with her other paw.  Katie spoke in a much softer voice, "Let's be naughty and fill up before dinner."  He blinked and twitched hard inside her, groaning again as she rubbed him.  Katie bit her lip and then gave a little tremble as she squeezed back on him in response, clutching her brother with her vagina.
 
Another terrifying voice up the stairs, closer this time. "I said come down now; your dinner's getting cold!"
 
They both gasped and Katie squeezed much harder on him, making him groan and tremble. "W-we're just coming, just have to put away Tommy's Wii!"  She locked eyes with him again, they were wide with excitement and longing, placed a finger on his lips as she held his warm scrotum. "I want to feel you inside me." A light squeeze.  She chewed her lip. "Every drop."
 
An unfamiliar moan escaped his curled lips as, shivering, he abruptly stiffened.  She felt his arms and penis go rigid, then jerk inside her, once, twice, thrice; a dizzying array of emotions crossing his young face.  He gripped her shoulders suddenly, pulling her hard into his lap; he sunk even deeper up her and gave a strangled cry.  It was loud, too loud, but Katie was oblivious, as his ejaculation finally erupted.  Staccato gasping matched staccato squirts that fired wetly into her again and again.  Squirts so hard she felt she should hear it; her brother pumped his sperm deep inside her vagina.  Jet after jet drenched everything, cub semen finding every crevice, every fold, covering it and then filling it.
 
Katie closed her eyes and softly murmured with bliss, drinking in her brother's pleasure while he shuddered and gasped.  This time it was a little too quick for her, but that didn't matter; a warm glow filled her body that was more than just her sticky vagina.  It was then, that the first tread of the stairs squeaked; they both gasped and clutched each other.
 
*******
 
"What the hell are those two up to?  It's not fair, it really isn't; I work so hard for all this."
 
Dad looked up from his coffee and nodded distantly. "I know dear."
 
"It's really not good enough.  Julian I'm going up there."  With an annoyed frown on her muzzle, Mum left the kitchen and began to climb the stairs.  Squeak.  Thump.  Thump.  Squeak.  She reached the top of the stairs and heard gasping, giggling, from Tommy's room.  Her irritation gently smouldered as she strode down the landing and stepped into their room, to see...
 
"Ack! 'Scuse me, Mum. We accidentally knocked a drink over!"
 
The twins bustled past her and into the bathroom, their paws wet and shiny with something.  She glanced back into the room and didn't see any of it on the carpet, thank goodness.  Sounds of splashing and running water came from the bathroom and she rolled her eyes, letting out an exasperated sigh.  "I want to see you both downstairs for dinner as soon as you've cleaned up; is that clear?"
 
In unison they answered from behind the door: "Yes Mum!
 
*******

Sleep.  Soft like liquid silk, enfolding her, enrobing her, tangible as a cloud.  Katie floated.  She knew he was inside her.  She could feel it, could feel him, especially that part of him.  The leopard hugged herself, shivering, cocooned in her own little world of thoughts and dreams.  Pleasure swirled around her like leaves caught in an autumn breeze.  Her breath caught in her throat and she felt her legs drawing up to her chest.  Colours now, sultry red rising through burgundy, orange, now yellow: flickering like fire.  She could feel the heat suddenly, as the colours jumped to blazing white, that special warmth, sticky and wet.  Inside her.  He was ejaculating inside her.
 
The maelstrom of colours and dreams abruptly collapsed inwards, inside, between her legs, and she cried out.  Wetness surged in her vagina as pleasure surged out, like ripples on a lake.  She clawed at nothing, at space, at the space between dreams.  All she was, all she could be, was pleasure, safe in her brother's arms.  His gentle form gradually coalesced round her while she hitched and mewled, holding her, making her warm.  Making her his.

*******

Katie frowned and adjusted the one piece swimsuit again, regarding herself critically in the mirror.  She'd not had it that long, just six months, so there was no way she'd outgrown the thing yet.  And yet...  The girl turned to one side, narrowed her eyes, sucked her tummy in.  It was tight, doing strange things to her usually sleek outlines, making bits stick out where they shouldn't.  With a soft sigh she let her tummy out again, gave herself another once over.  Katie was never one for eating a lot, but just lately she'd been ravenous.  It was starting to show; she really was going to have to be more careful, if she didn't want her tummy to keep growing.  This was no good, no good at all; she'd have to ask Mum for a new one.  A little self consciously, Katie picked up her towel, held it over her tummy and made her way outdoors.
 
*******

The garden was wide as their dreams, long hedgerows and flowerbeds seeming to stretch far into the distance.  Over there, the ochre wood of the summerhouse.  Further away the vegetable garden, next to it the raspberry canes.  There was the overgrown pond, wild reeds spilling over the ancient tiled surround, untidy.  There was the old elm tree.  Centrepiece of the garden however, perhaps even a little ugly in its starkness, the kidney shaped pool lay flush with the grass.  Sometimes the twins forgot just how lucky their family was to have one.  The heat was dropping out of the year like leaves, already they were beginning to turn, but a final warm weekend had made nearly everyone head for the garden.  Dad was busy in the garage on another of his 'projects'.

Mum lay on her side on the sun lounger, sunglasses over her muzzle, watching the twins.  Except...  The more the twins glanced at her, the more they realised she was fast asleep, wakefulness betrayed by the gentle rhythm of her breathing.  Tommy bumped noses with Katie and they grinned, floating with just the tops of muzzles and tips of their tails out of the water.  How close together could they float without anything else touching?  A soft gasp and Tommy felt his sister's smooth belly bump against his.  He smirked and they drifted slightly apart, trying again.  Just touching at the nose, drifting, pirouetting through the water, closer, closer.  Bump.  They both looked down this time, peering through the distorting water.  Tommy reached with a paw and touched her, gently ran it down her chest, her sleek underside, caressing with a familiar intimacy.  She closed her eyes, a soft smile brushing her lips; he quietly whispered to her.
 
"Better not let Mum see that, or she'll put you on a diet!"
 
Katie's ears and muzzle burned hot as an expression of shock, outrage and then hurt blazed across her face in record time.  Before he could say anything else, she turned her back to him and floated away.  Tommy's ears flattened to his head and he cringed, meekly following her, till she reached the far edge and clung to it.
 
"Katie, I..."
 
She sighed and waved a paw dismissively, ears back. "Just forget it."  Her tail lashed out of the water behind her, softly splashing.
 
He shook his head and floated across, until he could reach out and gently touch her shoulders.  She flinched lightly; he grimaced but persisted, grasping them and then drawing close.  His sister let out another sigh and did not draw away; her tail caught in the water between them.
 
"You learn that pickup line at school, champ?" She inclined her muzzle.
 
Tommy shook his head again, not that she could see, and gently pressed up against her from behind. "Don't be like that."  She sighed one more time, stiffened, but then finally relaxed in his paws.  His muzzle rested against her neck.  Gently, ever so gently, he slipped his paws under her arms, round to her front, and held her to him.  She gave a soft murmur and her ears came up, as those paws gently moved lower, caressing down her tummy once more.  Tommy's ears came up too, and he stretched his muzzle up to hers. "I happen to like it." He rubbed, rubbed down her tummy and briefly, between her legs.
 
Colour flushed her muzzle again, but she turned suddenly, staring at Tommy with a vivid intensity, "Promise?"  He nodded.  She looked at him for a long time, searching his eyes, seeing nothing but love.  He looked back with his soft smile.  Soon she was smiling too, and a little weight dropped from her heart.  The twins hugged, fitting together in the water, his muzzle on her neck and her muzzle on his.  Another smile found its way to her lips though; she hugged him a little tighter, rewarded with a gentle gasp; her brother's erection pressed against her.
 
Katie drew back, glanced at Mum, and gave him a naughty look.  Before he could respond, she suddenly ducked right under the water.  A moment later Tommy gasped and struggled as unseen paws tugged and then removed his shorts.
 
"Hey!"  The leopard exclaimed to no one who could hear, blushing as he quickly found himself naked.  But before he could even cover his modesty with his paws, hers got there first.  He shivered as they slipped between his legs, rubbing every part of him.  He bit his lip as she held his soft pouch, pulled at his sheath, rubbed him firmly up and down.  The cool water of the pool was nothing against his sudden ardour; he looked around, fighting to keep from gasping again.  Just when it could get no worse, he nearly cried out as warm lips found his tip and the boy sunk into her muzzle.

Slowly, agonisingly, she pulled back again, till his willy sprung free.  He was quivering all over, eyelids fluttering like they did, as she left him and darted to the other end of the pool.  Ears popped out of the water followed by a naughty smile; Tommy looked at her hungrily.  "Katie..."  He hissed, starting to move towards her.
 
She shook her head, swimming powerfully away.  "Nuh-uh.  Catch me if you can!"  With those words the chase was on, and Tommy groaned.  He'd always been a powerful swimmer, but never as quick as her, a fact she lauded over him all too often.  The cubs zoomed through the water, slick fur and slicker bodies, one naked and one not.  She held his shorts in her paw.  He came so close, so many times; they began to splash each other and laugh.  "Better try harder, spottybutt!"  Tommy growled and kicked off from the side, swimming, splashing, trying to send a wave of water her way.
 
"Tommy, Katie dear, please keep it down?  Your poor mother is trying to rest her bones here."  They froze as Mum stretched briefly on her sun lounger, and then rolled over to face the other way.
 
Tommy stealthily floated up to Katie, and she gasped suddenly as he gripped her from the front, "Gotcha!" he whispered as quiet as he could.  She rolled her eyes and dropped his shorts.  To the bottom.  He glanced down and then ignored them; the twins were floating out of their depth right now.  Tommy grinned and after a moment she did too, as they found each other slipping into another embrace.  His penis found her first, soft in the pool water but rapidly growing; it brushed against her leg.  The twins looked into each others eyes and her paws pulled him closer in an easy intimacy.  Mum shuffled and sighed on the sun lounger, getting comfy as her breathing became more regular. 
 
He glanced up with wide eyes.  Mum was right there; his heart thundered, and there it was again: a dangerous excitement now.  Mum was right there, and he pressed between Katie's legs, stiff and warm; only the smooth fabric of her one-piece was keeping them in chastity.  The leopard struggled not to make a sound, his fast breath soft in her ear.  Closer they hugged; she pulled; his eyes went wide as his willy begun to sink with the fabric into the cleft between her legs.  Katie looked at him, eyes wide, they both glanced over to the sun lounger.  She felt it too.  Trembling, he snaked one paw down between them, between his legs, between hers.  He pulled.  He pulled the fabric of her swimming costume to one side, and while Mother lay a few feet away, he pushed his stiff penis into Katie's vagina.
 
They stared at each other with deep longing and quivered; he hugged her, hugged her close, pressed his sister against the side of the pool.  As quietly as they could, the twins began mating in the water, sparing an excited glance at Mum from time to time.  Only soft pants and gentle splashes betrayed their incestuous coitus to anyone who might listen.  To anyone looking it might be a different story, as Tommy gently thrust in and out, in and out.  The water nearly hindered as much as it helped, washing away some of her natural slipperiness, but it was tolerable.  There was warmth between them, between her legs, warmer than the pool.  Tommy's balls were already pulled up tight and neat; not yet ready to do their thing, but keeping warm.
 
His muzzle on her shoulder and her muzzle on his, they held each other tight and mated, splashing.  Her vagina squeezed and they both gasped; she was warming.  Mum shifted on the sun lounger, making a very soft snoring noise.  Katie squeezed again, breath catching in her throat as Tommy worked his stiff penis in and out of her.  It felt so strange as they floated, as if in air, only the bump of the pool side behind to remind them otherwise.  Her one-piece was tight between her legs, pushed to one side to let her brother have sex with her.  She shivered and curled her toes; he groaned and continued to thrust. 
 
Katie squeezed extra hard and turned suddenly; had she seen something out the corner of her eye, movement in one of the house windows?  What if they'd been seen?  What if...  Tommy bumped his muzzle against hers and their eyes met, his were filled with pleasure.  He held her while he thrusted, safe in his paws, and he nodded.
 
"Do it."
 
Katie blinked, confused, then another shiver surged through her.  "W-what?"
 
His eyelids drooped and his tail peaked out of the water, it wouldn't be long now, "Please...  I want you to..."  He searched for the word; he'd heard it a few times but it seemed silly, "I want you to cum, and then I can..."
 
Shivers ran all up and down Katie's body now, making her tail puff out if it could, making her paws clench.  She looked at her brother as he held her, losing herself in his eyes.  Tommy groaned, trembled, pushed in to the hilt and stayed there.  She looked at him, as he looked at her, and then that unstoppable tingle began.  Breath catching in her throat, an intense spot of pleasure surged between her legs, then began pulsing outwards in waves.  Her vagina started rippling, squeezing in time to the ecstasy that was abruptly washing through her young body.
 
She saw Tommy's tail break the surface of the water, up high, watched bliss flood his expression, watched his muzzle screw up with effort.  And then, as he gasped, she felt him start flooding her.  She felt that sudden warmth, that burst of heat which could only spread, as his willy jerked again and again and again.  She felt the slippery wet spray of his seed as it jetted against her vaginal walls, and squeezed him harder; they both mewled.  Surrounded by wetness, soaked to the skin, with Tommy's help the twins became wet inside too.  They hugged each other so tight, one rocking against the other, gasping, trembling, moaning at their intimate release.  Mum snored on the sun lounger; the cubs watched her as they copulated.
 
Tommy ejaculated for a long time, or so it seemed, his shivers and grunts just went on and on.  Katie licked his ears, awash in feelings; she always liked to let him finish.  He was so cute when he was like this, maybe the cutest, completely at the mercy of his body (and hers).  When it seemed things were finally calming down, and he panted beside her, she gently tipped his muzzle her way and they kissed. The pair closed their eyes and kissed deeply, as siblings never should, as these twins happily could, so much in love.  The sun was going down and Katie shivered suddenly; it was getting cold.
 
"Let's go get dried up and play in your bedroom, what do you say Tommy?"
 
He murmured and then gasped as they slipped apart, as he slipped out.  She quickly reached down and tugged her one-piece back into place, like nothing had happened at all, like she hadn't just been mated and filled by her own brother in the family pool.  She kissed him again, on the nose, and then swam over to the ladder.
 
"H-hey!"  Tommy exclaimed groggily, pointing down at his nude state.
 
Katie giggled softly and began to climb out, pointing down at a dark patch at the bottom of the deep end, "There they are Tommy, fetch!"  Mum stirred, but didn't turn to see her daughter grab a towel and run off towards the house, fluids other than water quickly saturating her crotch.  Tommy went diving and found his shorts, blushing as he pulled them on quickly, hoping nobody had seen (never mind about the mating).  He gave a little gasp too; today looked to be one of the days when that erection just wasn't going away.  There was nothing for it, and he shyly clambered out of the pool, blushing.  Before Mum could say anything, the boy grabbed his towel and ran towards the house after his sister.
 
*******
 
The alarm softly sounded.  Six-fifty am.  The same as every day.  Tommy groaned and hugged Katie a little tighter; not ten minutes ago he'd finished filled her.  His penis still rested where he'd put it, but he had to go.  They couldn't get caught together in bed, in her bed, they really couldn't.  He couldn't help imagining it though, heart fluttering at the thought.  But they really couldn't, so he had to go.  

Just another minute.  

The alarm sounded again, five minutes later, Tommy groaned louder.  Reluctantly, so reluctantly, he pulled away, pulled out of her with a wet sound, shivering and gasping.  The leopard sat up on the side of the bed and looked at her, seemingly still asleep.  Her fur was all rumpled, where he'd been holding her, where he'd... mated her.  She lay in a light curl, soft girlyness embodied in a shape, her hair across the pillow.
 
Tommy leaned over to kiss her, pressing his muzzle to hers with love. "Goodnight Katie.  My Katie.  I love you."  As quietly as he could, Tommy got up off the bed, reset the alarm and crept out of her room, to his.
