Kasey reached out to her brother, as he passed her, entering the bedroom that should have been reserved for her and her husband alone. But Alex did not, by any means, respect the sanctity of it as he crossed the threshold and shrugged out of his T-shirt, dragging it carelessly up and over his head, hair ruffled. With his dilated pupils, there could be no question of what had happened and she made a strangled choking noise as he padded in, stalking the couple on the bed as if he was a wild animal.

“What a pretty girl..." Alex rumbled softly, looking down at Helena splayed out and panting. “I think you need a good fucking..."

Kasey flinched: that was her daughter he was leering at! And such language! Could she get her away? But it was too late to stop anything and, well, what could she really do? Helena scrambled up on her knees, reaching for Alex's hard cock, jutting out from his crotch already eager for attention. And so Kasey stepped back to the side of the door, refusing to interfere as it seemed that, as long as she didn't put herself in the firing line, those infected were hardly interested in her.

Nothing could be done, she repeated over and over to herself as her brother locked lips with her daughter, bearing her back onto the bed, her hands wrapped around his throbbing shaft, pulses of pre-cum spurting onto her smooth stomach. She had to keep telling herself that... For she knew, that there was a dark, tiny part of her that liked what she was seeing too, but she thrust it down where she didn't have to pay any attention to it, biting her lip and telling herself that it was just because she didn't want to get infected by the parasite too.

Kasey trembled. Then it would be her fucking her brother! Good heavens, she hadn't thought of it like that!

Helena didn't seem to wait as she hungrily moaned into her uncle's mouth, clinging to him as her father, his cock hard and ready once more, moved up behind her. The duo shifted her seamlessly up to her knees, handling her like a toy that also had a very large say in just how it was used, with Curtis' cock brushing up to her pussy lips.

The effect on the young woman was electrifying. Arching her back, she ground her buttocks back on her father's cock, letting his shaft, slippery with cum and her own arousal, slide back and forth between her ass-cheeks. He growled lustfully, curling his fingers around her shoulder, and then the back of her head was pushed down Alex's lightly toned chest and stomach to where the bobbing head of his cock waited.

Her lips opened at precisely the right moment and Helena's moan was swallowed up as she gulped down his shaft, taking him to the back of her throat in one fell swoop. Although her chest shuddered, she didn't heave and gag nearly as much as Kasey would have – that was if Kasey had ever thought of taking her brother's cock into her mouth! And she wouldn't have thought that – not at all! But it was hard to watch and not have her own needs sated and Kasey, very unwillingly, found herself licking her lips, wondering just how it would feel. Would he be as thick as Curtis? Cut too? She craned her neck to see, but couldn't quite make out as he fed Hel his cock with a moan, head tipped back and Curtis cramming her sloppy cunt full of his dick at the same time.

Kasey shivered. How could it possibly be so erotic to be the voyeur? It shouldn't have been so and certainly not so with who she was watching. Did it even count as her husband cheating on her if he had been forced to do so by the parasite's venom? The thought excited her more than it repulsed and she let out a breathy moan, no longer concerned about anyone overhearing her as her hand crept down the front of her trousers. She'd been getting ready for work, dressed relatively smartly in business-casual, but the button popped rudely loose as she pushed deeper, jamming her fingers up into her shockingly wet pussy as Alex fucked her daughter's mouth as if it was her cunt.

Oh, how she hoped he'd really fuck her!

Curtis grunted something, but she didn't quite catch it. Alex did, however, and smirked, leaning over Hel's back to put more power into his thrusts. Her daughter may have squeaked or not, but whatever sound she made was muffled by the cock between her lips as he slammed into her, cheeks bulging from the sheer effort she had to draw on simply to contain him within her lips. Her uncle, however, seemed to know that she could take every inch – and more – winding his fingers tightly into her dark brown hair as Curtis pulled her hips back, impaling her on his shaft.

The wet sounds of their lusty intercourse echoed through the small room, the only muting effect that of the curtains and carpet, though the former was hanging open, letting a stream of morning sunshine into the room. Helena's father grunted as he slammed into her already well used pussy, the sloppy mixture of their sexual fluids making his penetration slick and easy, almost as if she was a whore ready to be fucked and bred over and over again. But Helena was no such wanton princess and relished everything she was given, slurping and suckling on her uncle's cock as he drew back. So engrossed was she in pleasing his achingly hard shaft that Hel nearly forgot to breathe and sucked in desperate gasps through her nostrils as her eyes rolled.

Kasey gnawed the inside of her cheek, rubbing her clit in small, tight circles as she watched, cheek pressed to the frame of the door. Perhaps she should have been a bit more concerned with why and how they were paying her absolutely no attention at all, so caught up in their enjoyment of one another that she may as well have not been there at all. It was difficult to, however, with the burning need curling through her, making every inch of her body feel hot to the touch – searing with sheer, raw need. As her husband let his head fall back, lips parted in a feral moan that spoke of so much repressed need, Kasey let out a breathy little gasp of her own, hips rocking slowly as if she wished it was her between them.

Not that she liked Alex like that, of course, she hurriedly corrected herself. No, it was nothing like that. Just her own desire to be fucked, to be rammed into just like her daughter was enjoying. Her eyes took on a dreamy cast, lower jaw slack. Yes... Her husband and her, the curtains blowing open in the breeze and the whole day just to themselves to fuck and fuck and fuck some more again. His thick shaft spreading her open and grinding up to that spot within her in just the way she loved. Kasey groaned, fingers pressing deep up into her cunt as Helena gagged softly around Alex's cock, his hold on her hair hardly allowing her to get a good breath in. Oh, yes, she'd like that very much.

There was nothing like a good fuck, after all.

What was she thinking? Kasey jerked to attention, cheeks crimson and shamefully ripping her hand out of her pants, eyebrows so high that they disappeared beneath her long hair. She couldn't be getting so turned on by what she was watching – had she been infected by the parasite too? Suddenly, she leapt back, wide-eyed and chest heaving. Could it be? Was that why she was getting so horny, lusting over a scene that, by all definitions, should have repulsed her?

Pulling her T-shirt out from her chest, she ran her fingers over every inch of her body that she could reach, checking unmarked skin for that telltale bump – or whatever the parasite would leave behind – that could only be one thing. Her heart tightened in her throat, a lump too thick to swallow, and even the rampant sounds of intercourse a mere breath away could not dissuade her from her fervent inspection. Her fingers were still slick with her own pussy juice as she ran her hands down her legs and she moaned against herself, the shiny trail betraying her true feelings about the whole matter.

But there was nothing on her body to suggest that she'd been bitten and so her attention was, rather rudely, drawn back to the lustful scene playing out, Curtis grunting and groaning as he filled their daughter. Alex seemed to be getting close, panting heavily with beads of sweat running down his back and his skin heating up in red blotches, the skin of his cut shaft pulling gently against Helena's lips every time he drew back. Yet every withdrawal came with a renewed promise to thrust in with ever greater power and he did just that, driving the tip up into the back of the young woman's throat as she rocked and gave the best moans she could around his length. As quiet as they were, it was impossible to deny just how much she was enjoying it and that was only further enhanced as her body was undoubtedly clutched by the claiming hand of another orgasm.

Mesmerised, Kasey clutched both hands to her chest as she watched her daughter orgasm for the second time, hips rocking and grinding back into Curtis' hold as she fought to focus on sucking the cock before her. But there was little she could do but surrender to every sensation as her body fell outside her control and Alex ground deep into her mouth, pre-cum bubbling out from the corners of her lips as if she simply could not take another drop. And yet there was more to come, her fertile, young body arching and twisting between the strong men, her only anchor in a storm of lust.

Despite having climaxed only a short while ago – not that anyone was keeping track – it was Kasey's husband that reached his peak as Hel's pussy squeezed and massaged his cock. He rumbled a moan that was abruptly cut off, driving into her with a sudden series of short, sharp thrusts, need rising through every fibre of his being, near enough palatable in the air. Curtis ground his hips up to her round buttocks as he ejaculated for the second time and, if anything, his spurts seemed to contain an even greater volume of virile seed than before. Kasey could not have honestly said whether or not her daughter was on the pill, but it was too late to think of that as his cream filled her right to the very brim.

Of course, that left one – the one who had been the last to join the party of three. Alex moaned like a teenager all over again – yes, Kasey had heard him in his bedroom when he'd thought the rest of the household had been asleep – rocking up into Helena's eager mouth as she whimpered around his cock. There was little he could do to possibly hold back, even if he'd wanted to, with her tongue pressed up to the underside of his cock and it was with a lusty groan that seemed to rumble up from the pit of himself that he finally jerked and shuddered into a crudely abrupt orgasm.

Kasey sucked in a breath, watching just how her brother's head turned from side to side, his jaw working as if he was going to clench it and then simply chose not to at the crucial moment. Her little brother, who definitely wasn't so little anymore, filled her daughter's mouth with shallow thrusts, keeping his cock as deep as possible and hardly pulling back before rocking forward again with erratic power. That didn't stop trickles of cum from drooling out from the corners of her lips, however, as Helena gulped down all she could, the rest dripping down her chin to stain the sheets of Kasey's marriage bed.

She should have been expecting it, but her orgasm caught her off-guard all the same. The rush of heat flooded every inch of her body without due warning and Kasey cried out, hips jerking and bucking against her own hand, back in her underwear with her fingers buried in her hot snatch. Helpless in its clutch, all she could do was ride out her climax as her legs went to jelly and Alex huffed as his softening cock slipped from his niece's lips, a splatter of creamy cum slick across her lips. Where the scene should surely have disgusted her, Kasey whimpered and gasped like a virgin all over again, legs slowly buckling as she dropped to her knees and leaned into the wall for some kind of support.

Fuck...

Breathing heavily in the aftershock of climax, Kasey bit her lip and crept around the door frame to watch their lust progress, each participant shifting position for another round that would undoubtedly drive their voyeur to another delicious orgasm. They still took no note whatsoever of her presence as Helena whined and groped both male's cocks at the same time, eagerly driving them back to full hardness just so that they could fill her again.

Again and again, they fucked, the morning stretching on as they took little time between climaxes, all caught up in throbbing, undulating lust that carried them along with it like the rising tide. Three bodies moved together in idyllic harmony and Kasey could do nothing but helplessly watch unless she wanted to be a part of it herself and, like them, lost.

Yet were they lost? That little stubborn voice in the back of her mind just wouldn't shut up. She didn't really know what was going on in their heads and, really, she couldn't ask them either while they were... Well...

Blushing, Kasey gnawed the inside of her cheek until it bled. And with the metallic rush filling her mouth, something snapped inside her.

She couldn't stay, couldn't watch as they re-positioned her daughter for what had to be the umpteenth time, desires hardly quelling as the day dragged out. So caught up were they in their own lust – courtesy of the parasite's venom, or whatever it was – that Kasey doubted they would even notice the passing of the day at all.

She sighed and trailed her fingertips across the inside of her wrist, absent-mindedly checking her own pulse, though it was not as if it would jump or race or do anything else untoward. Hells bells – she didn't know what the parasite would do to her if it got her too! Except…that.

Shaking the image of her husband and daughter from her mind, Kasey pressed her lips together and stumbled down the stairs, taking the steps two at a time in her haste. She had no fear that they would follow her and supposed she had to feel at least a little bit grateful that they were harmless. There were worse things to escape into the world at large and making love not war was certainly the lesser of two evils.

Her feet had hit the floor at the bottom, the sounds emanating from upstairs making her wince. It should have been her and Curtis, not him and someone else. Her lips turned down, a headache pounding at her temples. Anyone else. Anyone else would have really been better, but no – it was done and doing and all she had to do was make sure the knowledge of it never, ever left her house.

Piece of cake, right? Groaning, she pressed her head to the cool of the wall, but nothing she did, no pressure she could create, relieved the throbbing pulse of anguished confusion within.

Drink. She needed a drink. And not just a glass of water either.

It was too early for one, but who would know? Shakily, she paused at the liquor cabinet in their living room, something they usually only delved into for special occasions. It wasn't right. She wasn't setting a good example for her family, her daughter. What would Curtis think? She had to help them – somehow. But what could she actually do to help?

Swallowing the lump in her throat, she closed her eyes, swaying from side to side as if she was already taken drunk by simply standing in the mere presence of the cabinet. She was the one who hated dipping into it for anything other than special occasions. So why was she suddenly so thirsty? Was it right? Was anything right anymore?

Ah, but what did it matter? Kasey yanked open the door with a grimace on her lips and grabbed the first bottle that her fingers touched, manicured nails curling around the neck. Vodka. She barely hesitated as she dumped a sizeable measure into a tumbler, one of the good glasses with the right rim for the drink. It splashed into the bottom, burbling companionably as it was released from its glass prison, soon to find its end in her stomach and bloodstream.

Kasey took a sip and tipped her head back with a sigh, the glass warming to the touch of her hand. Just what she needed. Orange juice on top and it would be a screwdriver or something fancy like that. The right kind of alcohol and she could pretend it was a mimosa. That was posh.

“What else am I going to do?" She said to herself, sitting on the edge of the sofa cushion and reaching for the remote, if only by autonomy alone. “It's not like any of are actually getting ourselves into work today."

She laughed at her own joke, but there was no one there to hear her and she scowled unprettily at the television screen as it blinked onto the news.

Destruction, death, despair. Kasey made a face as a very serious newscaster shuffled his paperwork. How much do I wanna bet that everyone was affected by the parasite in the same way?

_ _

Belatedly, she gulped and darted to both front and back doors, ensuring that both were locked. Of course, Alex had left one open, but what more could she have expected from her silly younger brother? She scowled darkly at her reflection in the hallway mirror as fear lent speed to her feet, shoulder ramming into the wall without pain. He never had his head screwed on right, the silly boy, always thinking of something else. Kasey snorted and pressed the back of her hand to her mouth, finding her lips wet. Probably much the same as what he was getting up to at that very moment, if she was correct about how he had continued on in life.

Perhaps that was unkind of her to think, but she wasn't thinking clearly as she checked each window, finding them all, thankfully, sealed tightly and with the outside world appearing blissfully, ridiculously serene. For an extra measure, she closed the curtains in the living room too, sealing herself away in a false twilight. Only then did she return her attention to the screen, tipping her body in to a near enough foetal position as she drew her knees up to her chest, the vodka slowly diminishing in the glass as it made trip after trip to her lips.

“Residents are advised to stay indoors, although the effects of the parasite's escape have not proven threatening to the general population, as yet," the newscaster read – hadn't she seen his name about somewhere before? – with a frown that helped convey just how serious his words were. “We do not know as yet how far the parasite has travelled, but, from the spread of the infection, it seems that it may now be passed from human to human."

He frowned, lips twitching ever so slightly. Kasey leaned forward, eyes wide and drink forgotten, if only temporarily.

“It is, of course, passed on through intercourse, which means that husband and wife, civil partners and so on, are the most commonly infected. It has spread further than expected as the parasite's venom is causing individuals infected to behave…" He seemed to struggle with the words, a finger sliding within his shirt collar. “…Not as they normally would."

The newscaster ran his fingers through his gelled and styled hair, addressing then someone out of sight of the camera.

“What? I can't say that! Not on the morning news! It's not right!"

The argument was short-lived and he returned to the papers before him, red-faced and eyes popping out of his fat, meaty face.

“That said, there appears to be no active harm caused by the parasite and those affected are not showing any violent tendencies. We do not yet know just what the parasite will cause, but we strongly advise those who are not infected to avoid contact with the infected, for their own safety."

Kasey's eyes flicked upward as a thump sounded from the bedroom – her bedroom. Was it too late to run up there and lock them in? Probably. But nobody seemed all that interested in her, it had to be said, so she was probably – probably – okay.

Was that “probably" enough?

“Do not engage with the infected," the newscaster continued on, likely ignorant to the turmoil he was very likely causing to the many other families watching the news while their loved ones lost their sense of selves. “Do not allow them to touch you and do not be coerced into acts that you may later regret."

Not very professional of a newscaster, she thought to herself, smirking as he cleared his throat yet again. Maybe he's a prude in the bedroom and just doesn't know what to do when he actually has to talk about it? Or he just really needs to get his ass laid.

_ _

She started, her glass already empty. Chuckling to herself, she turned off the news and set it aside, leaning back into the comforting, soft cushions of the sofa. She hadn't slept all that well the night before, perhaps knowing, subconsciously, the trials that were to come with the day. Even though the vodka had not yet really kicked in, she giggled to herself, eyes heavy and half-lidded. A little sleep would do her good, she reasoned. Just a little rest to come back to herself some. She'd be able to handle everything so very much better if only she could sleep it off for a little, mini while…

Thump… Thump… Thump. Thud.

Someone traipsed down the stairs, landing heavily with each step. Kasey stiffened, a hand that she could not see or really feel locking around her throat, squeezing tighter and tighter and tighter as she struggled for breath that was not to be allowed.

Her senses snapped back to her and Kasey had just about dug her heels into the carpet, the only light glancing off her features that of the rambling television screen, when Curtis flung open the living room door. She exhaled in a rush of breath and braced herself for the worst.

“Good morning, dear wife!"

Curtis beamed as he bounced into the room, naked from head to toe and with a great deal more life in his form than he had ever demonstrated before ten o'clock in the morning. Blinking, it was all his wife could do not to snap her fingers in front of his face, just to make sure the man was actually of the waking world.

Her husband grinned foolishly, eyebrows pushed so far up into his rather dishevelled mop of dark hair that they nearly disappeared altogether. Kasey frowned. Had he even stopped to brush it that morning? Honestly! What was it with men and thinking they could roll out of bed without spending a single moment on personal grooming?

The man before her who looked like Curtis and yet was not at the same time laughed and threw his head back, teeth flashing white in the dim light.

What in the world…

It couldn't have been her husband – no way in hell or heaven! She was the morning person, not him! Her mind whirled. Did the parasite change personalities too? Was it a new development, something that the news and research teams just hadn't picked up on as yet?

Was she the first to know? She had to be cautious, wary. Kasey took a deep breath through her nostrils, chest expanding as her husband's eyes locked onto her.

“Hi…Curtis," she said slowly, shrinking away from him as he tried to touch her arm. “Oh, no…honey, no…"

He pulled back, confusion flashing across his features as his eyebrows knotted together. Kasey's heart raced, making up for all the beats it had skipped in the turmoil of the morning. Quick, quick – quick!

“No, dear," she pushed the words out too quickly. “It's not you, just… No! Don't come any closer! Don't touch me, I-I think I'm coming down with a cold and wouldn't want to get you sick too!"

She snapped the last word, but Curtis didn't seem to really take it in, spinning across the living room like a top to flop into one of the uncomfortable armchairs that they usually offered to visitors they didn't like very much.

“Alright, well, if you insist." He shrugged, clearly nonplussed. “Was there anything for breakfast today? I'm starving!"

Kasey raised an eyebrow, thankful that she'd avoided questioning and yet...still incredulous that, after everything that had happened, his dominant feeling was, of course, hunger. It would be just like him though, really just like him.

Or was it? Was he the same? And, if he was not himself, how could she tell? The little voice in the back of her mind whispered, cruelly, that surely the sight of him fucking their sweet daughter should have been evidence enough that he was not in his right mind, but she thrust it down and down and down, locking it away where her rational mind could ignore it, if but for a time. Yet she had to know.

Eyeing Curtis from the sofa, Kasey took a deep breath.

“How are you feeling?"

The words came out slowly, thickly, as if she was the one who was unwell, not him. And that may have been true for all the reasoning that reverted to her in the depths of his gaze.

“Me? I'm feeling amazing, my dear wife!"

Kasey winced.

“Please don't call me that."

“What?" Curtis drummed his fingers on the arm of the chair. “Why don't you like it? Is there something wrong?"

“Well…" She hesitated, but ploughed on regardless. “There is. There is something wrong. Very wrong, in fact."

Curtis stared blankly at her.

“And are you going to share that with me? What's so wrong?"

It was almost a relief to hear some of the joy melt from his words, but her heart throbbed with guilt a moment after the thought crossed her mind. It wasn't his fault really. He hadn't asked to be bitten by the parasite or whatever the damned thing was. Yet a small part of her narrowed its eyes at him, a snake's head rising from the pit of anger that boiled into her frustration at being so aroused at something so very wrong. Kasey clenched her jaw. Just why did Curtis have to make her day miserable? Couldn't the parasite have chosen another house, another family? Would it really have been that difficult for the thing to go elsewhere?

But Curtis stared at her still, eyes so hopelessly clueless that the anger sizzled away, sulking in a dark corner of her mind where it swore it would have its moment – if not quite that one.

Kasey coughed into her hand, clearing her throat.

“Well..."

The words stuck in her mouth, refusing to leap from her suddenly far too dry tongue, and yet she forced them out anyway, ploughing on through what she could only hope was the very worst of it.

“Don't you remember what you did upstairs?" She blurted out, clutching at straws. “You know, Alex was there. And our daughter. Hel. Helly. She was there too along with you and Alex and that thing... The thing you were doing..."

Well, she could at least attempt some manner of tact, but her words took on a frantic, desperate edge as they spilt from her lips so rapidly that it was as if they could no longer bear to be contained. Curtis smirked, an eyebrow cocked above his left eye.

“Ah, yes, I was wondering when we'd get to that."

Kasey's heart skipped a beat.

“So," she said slowly, giving him ample opportunity to jump in. “You remember what happened then...do you?"

“Of course, I remember, darling," he said with a low chuckle that seemed to rumble all the way up from his gut. “It was great fun. I don't know why you didn't come in to join us, but you're always so polite, maybe you just didn't want to disturb. That would be like you."

Kasey blinked at him, taking a moment to collect herself while pretending that her mind had not completely and utterly locked up.

“You m-mean," she stuttered, fumbling and grabbing for words before they fled from her grasp once more. “You remember all of that? This is you talking to me now? Not a sex zombie?"

Curtis threw his head back and laughed, white teeth flashing.

“A sex zombie?" He bellowed, slapping his bare thigh. “Where the heck did you get an idea like that from?"

The heat of humiliation, so unlike the raw flush of orgasm, flooded her and Kasey straightened her back, teeth coming together to hiss out the words that followed.

“Fucking our daughter with my brother is a start of an idea!"

It was Curtis' turn to blink, in a rather dumbfounded fashion, at his wife.

“Yes?" He rubbed his chin. “What's the problem? You know I've been looking at her like that."

Curtis' lips parted, a worried look suddenly crossing his expression. And, for a moment, Kasey thought he realised, that he knew the seriousness of his actions.

“Why," he pressed on, leaning forward in the chair, “didn't you like watching?"

His wife pulled back, eyeing him incredulously. It was all she could do to stop herself from raising both eyebrows cartoonishly.

“I..."

What could she say? Think, Kasey, think!

“I... Yes..." The words came out in the wrong order, one in front of the other that should have been behind and to the side. “Watching, yes. Nice to watch."

She fought down the urge to retch and took a deep breath, steadying herself. And yet it was to no avail as, when the words came, they were as hot and vicious as the roiling guilt in her core.

“But that doesn't mean it was something I enjoyed!" She snapped, struggling with the words she wanted to force out. “What are people going to say if they find out about this? You can't do...that with our daughter!"

“Oh, Kasey!" He laughed and shook his head, eyeing her sympathetically as his lips twisted. “There's nothing bad going to happen, I promise – that's what you're worried about, isn't it? You think I like fucking Helly more than you?"

“What – no! That's not it at all!"

“It's okay, really," he said, holding his hands, palms out, as if the mere action alone would placate her. “I promise I'll always come back to you. You're my wife, after all, and trust me when I say that no one ever could replace you."

As much as the words warmed her heart, they were not the ones she wanted to hear, but she didn't get the chance to interject as the door creaked open behind her. Curtis' face broke into a grin once more and he waved whoever was on the other side of the threshold in with abject enthusiasm.

“Alex! My friend! Do join me!"

Kasey's head whipped around, eyes wide, as her brother stalked into the room, a wide, toothy grin on his lips that seemed to convey a great deal of contentment in the whole lark. Alex took little notice of her, however, exchanging only a high five with Curtis before slumping to the living room carpet, right in the centre, and rolling onto his back.

“Uh..." Kasey opened and closed her mouth several times, searching for words that seemed slow in coming. “Hi? Alex? Do you know who I am?"

As silly as it seemed to ask when it had already been clear that Curtis knew well enough who she was, she had to anyway. And the answer she got was the usual disappointing one that, in all honesty, she should have expected from such a brother.

“Sure I do, Kasey, you're my annoying older sister." He rolled his eyes. “Nothing ever changes like that, huh?"

“Uncle! You said you wouldn't leave without me!"

Hot on his heels, her naked daughter bounced into the room and Kasey suppressed the urge to cover her eyes, though she wasn't quite sure whether she should have been covering her eyes or Helena's. She winced. It was not as if the young woman, her own flesh and blood, hadn't seen it all before anyway. Hell, if she'd not been a virgin before that morning, she certainly wasn't one anymore! But that wasn't the sort of thing she'd have shared with her mother, oh no.

Alex grunted as Helena prodded him with a toe, arms crossed stubbornly across her chest as she demanded a response.

“Sorry, Hel," Alex chuckled softly, hands back behind his head. “I didn't think you were that far behind."

Her hands slid over his stomach and chest as the young woman knelt over him, straddling his hips with shocking familiarity. It seemed to take nothing at all for his cock to rise to the occasion, grinding up hard and throbbing against her perfect backside and, watching from the sidelines, Kasey covered her lips with one hand, eyes wide and despairingly childlike.

But there was nothing she could do but watch. Or, at least, that was what she told herself. It was, perhaps, the only way she could possibly get through the erotically spellbinding horror of the whole debacle.

“Are you glad you're finally fucking me, Helly?" Alex whispered to her as if there was no one in the room but them. “You said how much you wanted me. Well, now you've got it. You've got me and everything else you know you ever wanted."

Smiling, Helena tapped the side of her nose, raising her hips up enough to draw the tip of his cock up to her wet snatch with her free hand. It was all the answer she needed to give as she sat back, sitting down on her uncle's cock with a low, throaty moan that rang across the small living room.

Kasey squirmed in her seat, knees pulled all the way up to her chest. Oh yes. She was definitely enjoying herself. No doubt about that.

But the fun laid out on the living room floor was not solely for Alex and Helena to enjoy. Hel had barely risen and fallen on that thick shaft more than a few times before Curtis scrambled up and out of the hair, hard cock bobbing before him as if to point to his mark. And the mark he clearly had in mind was Helena's mouth, spread into a lewd 'O' as she enjoyed her uncle's cock.

Feeding his daughter the cock that she had savoured more than once already that morning, Curtis let out a low, long groan that seemed to encapsulate his need and that of everyone else in the room too. Helena giggled, batting her long eyelashes up at her father until her nose pressed into the light smattering of pubic hair, perhaps left after his last grooming session, and she was forced to look away.

“Helly," he breathed. “Your mouth is so sweet..." He grunted, eyes half-closed. “So warm and wet..."

As ineloquent as the words were, she murmured her approval around his shaft and, still riding Alex's cock she suckled on her father's shaft hard enough to make her cheeks hollow in gently. Curtis grunted and rocked lustfully into her mouth, every thrust pushing the light curl of hair at his crotch up to her nose, but she made no complaint, taking her father into the back of her throat as Alex's fingers brushed her clit. Everything they did to one another seemed to drive on their lusts, innocently raw need, to ever greater heights and the three bodies that she'd thought she knew so well, rocked and ground together in a cacophony of lewd moans.

Trembling, Kasey bit the inside of her lip until it bled, eyes riveted on the action. No longer did it feel illicit to watch when they were so openly putting themselves on display for her and she rubbed a hand over her breasts, teasing her nipples into hard buds of flesh through the fabric of her T-shirt. Briefly, she considered taking it off, but perhaps that would have indeed been a step too far and she settled for squeezing her thighs together, enjoying the wicked squelch of her own sexual fluids soaking through her underwear. No one knew just how much she'd enjoyed watching the scene in the bedroom and, even with the morning drink coursing through her mind, the desire to climax again thrummed through her veins, calling her back to the domain of pleasure.

They, however, paid her no mind, much as they had done in the bedroom. Alex played his fingers over Hel's clit and pussy lips, spreading them wide as if to better enjoy the sight of his thick shaft ploughing her. She moaned and groped her own breasts as she rode him, dropping to her knees to keep him more deeply inside her, and suckled fervently on her father's cock, pre-cum dripping down her chin as he drooled wantonly.

Unable to drag her eyes away from the sight, Kasey caught her breath as her brother's cock tugged and pulled at the sensitive folds of skin wrapped around it. Her clit throbbed obviously and she could have sworn that it was larger and more flushed with blood than that part of the female anatomy had much of a right to be, but it was difficult to tell with Alex fingering it, teasing his niece to an ever greater fever pitch of muffled moans.

Kasey would not have said that Helena was at their whim, but the way her body moved between the two men was entirely reminiscent of a puppet on its strings, controlled beautifully by a skilled puppeteer. As Alex thrust up into her, planting his feet for better leverage, her eyes rolled back into her skull, slurping and gulping lewdly around the driving shaft in her mouth, as if it was only an action that gave her more pleasure and anything more than that was simply a bonus.

Heated need crept through Kasey, so slowly at first that its reach was nearly imperceptible, but her constant shifting and squirming, wanting to rock her hips, betrayed her own need even to her worried mind. Holding her breath, she tried to steady herself, but a particularly loud groan from Alex called her attention right back to the present, demanding that she watch and listen and enjoy every damn second of their debauchery.

Curtis, however, was the first to show signs that he was getting closer to climax, his thrusts speeding up as he fucked his daughter's mouth as if he was filling her cunt once more. How did he cum so often and so quickly? That was certainly something Kasey would have liked to know – and wouldn't have minded experiencing for herself, if not for the unknown nature of the parasite still – but she at least had a front row seat to every drop of the action, quite literally.

And then something that she didn't think happened outside cheesy porn movies happened, in such perfect harmony that it took her breath away. Helena shuddered and jerked in orgasm, grinding her hips down on Alex's cock just as he too hit his peak, a free hand latching down on her hip to keep his shaft as deep inside her as was physically possible, her passage clenching down to milk him for all he was worth.

That should have been the end of it, their climax tapering off while Curtis found his own, but the oldest and most experienced of them was already there. With a long, low moan that seemed to well up from deep inside, Kasey's husband juddered up to Hel's lips and emptied his load as his balls swung lightly up to her chin. Her throat worked obviously, gulping down every thick spurt of seed with such surprising skill – perhaps her earlier experiences had lent her some practice – that not a single drop bubbled out from the corner of her lips.

Even Kasey had to be impressed, if in a twisted, motherly way. A very conflicted sort of way.

Exhausted from their joint high, if but only for a moment, the trio slumped into one another, Alex's head falling back to the carpet with a weak, yet satisfied, chuckle.

“Damn, Helly..."

Kasey shivered. Oh, those words...

Curtis was by far the least far gone in the afterglow of the three, however, and ran his fingers through his daughter's hair as he locked eyes with his wife.

“Are you going to stop staring?" He grunted, hips shuddering as his softening cock slipped from their daughter's lips. “Kasey... You watch us like a hawk, darling."

He put extra emphasis on the last word, a smirk on his lips. Shrinking back, thighs quite firmly pressed together, Kasey shook her head.

“No."

“Yes."

Holding out his hand, Curtis, her sweet husband, beckoned her in. Ignoring them, Helena brushed her lips sensually over his balls, covering them in adoring kisses as she cleaned his cock of slick, dripping cum. His attention on Kasey, Curtis smiled with disarming charm.

“There's no room for inhibitions here, sweetheart. Why don't you let go too?"

And Kasey knew he was quite right. They'd demonstrated that more clearly than anything else, the ties that should have held a family together raising a deeper need for father, daughter and uncle. She could join or she could not, taking her husband's offered hand or...not.

Shaking her head, Kasey whimpered, pressing her fingers to her lips.

What would a voyeur do?
