Part Three: Finale.

A feminine battle cry and masculine growl in familiar voices erupted behind Jennifer and Nathan. Turning in shock they witnessed the farthest pair of their naked copy-cats clashing at the end of the red carpet.

Not-Nathan barrelled across the short distance with his broad arms extended as Not-Jennifer arched her back into a lightning-quick back flip that ended with her athletic thighs locked around his thrashing head and her long autumn hair brushing his staggering feet.

“If you are inclined to more aggressive bedroom play, we can accommodate great feats without any cosmetic change to either of your bodies.” Heather moaned, as her Not-Nathan slipped a hand into her blouse revealing the gentle slope of a large creamy breast cupped by a white satin bra. Her nimble hands never left the clone's raging erection though as she continued. “Bones can be reinforced, muscles and tissue density increased, natural regeneration of injuries reduced to a fraction of your current healing rate.”

The backwards hanging Not-Jennifer was struggling to get an arm-lock around Not-Nathans knee as the wrestling pair swayed then crashed into the carpeted floor. The Jennifer copy gasped as the Nathan trapped between her thighs did something that made her slender hips twitch before letting out a wicked little giggle and punching him hard in the calf.

“No fair, you Natty pounder!” She scolded before pushing long silken locks out of his prone lap to reveal his jutting erection resting against his ripped stomach. “If you wanna fight dirty then two can play by those rules.”

With that she seized her lover by the base and ran a slow languid lick up his steely length before taking him into her pretty mouth with a furious passion. The two grappled and writhed, rolling on the ground like Grecian wrestlers as they fought and fucked each others faces with all the fury of a gladiatorial exhibition.

“We have seen such performances before in the Outer Rim Worlds, Heather.” Nathan said, turning them both to face the crimson-haired Haardaxian. “While it is certainly entertaining, that is not why we are here.”

Heather, for her part, was plastered up against Not-Nathan’s side. One long sleek leg was wrapped around the doppelganger's thigh and her blouse was now open as she continued stroking its rigid man-meat and rubbing her face against its strong chest.

Jennifer felt her own nipples hardening as her Nathan, the real Nathan, kneaded her tight ass and began running his hand lower, digging deep into the firm valley. Her own arms were wrapped tightly around him as her hands quested over the rocky muscles of his back and chest. Slowly drifting downwards, towards parts well known.

“Mmmhmmm~ A poor first guess, but by my own count I have five remaining.” Heather gasped as Not-Nathan pinched a nipple through the shiny fabric of her bra. Then nodded towards the next couple adjacent to the first still rolling around on the ground shrieking in a mixture of **** and ecstasy. “Perhaps you have acquired a taste for the exotic and uncanny.”

The two simulacrums eyed each other hungrily as they slowly paced towards each other. Each step saw a dramatic physical change come over them.

Not-Jennifer’s skin took on an organic green tint and a short layer of velvety fur sprouted across her epidermis. Her eyes grew large and silvered as her lips became pronounced and took on the hue and softness on rose petals. It was a distinctively alien and vegetative look and impossibly alluring. A sweet pollen-like scent wafted on invisible breezes around the couple.

Not-Nathan was… elongating. There was no other word for it as his physique stretched and slimmed down in places as it bulged and distended in others. A russet red mane grew around his neck and the pupils of his eyes were changed into vertical slits. Claws replaced nails and white stripes slashed through the dark hair on his head.

Soon it was a large feline humanoid that met the plant-woman version of Jennifer in a ravenous kiss. His long furry arms wrapping around her soft pliant body and dragging her into his clawed clutches as he devoured her rose petal lips.

“A rose by any other name would smell as sweet.” Jenny whispered up to Nathan as they watched the two variations of themselves moan into each other's mouths and drank in the intoxicating floral scent of the horny writhing dryad. “Heather is getting warmer, my Love but is still some ways off I think.”

"I think I make quite the dashing Shraddash hybrid." Nathan chuckled, brushing his lips across hers as Jennifer found his turgid throbbing member and squeezed it through the insubstantial synth-fabric of his bodysuit. "But I agree, such play is not for us. What would the shareholders say?"

"All changes are reversible at will…" Heather panted as the Not-Jennifer partner of the Nathan she was grinding against, slipped up behind the Haardaxian beauty and began nibbling on her ear. "You are both so deliciously distracting… aaah~! It is interfering with my reasoning and deduction processes."

Her dark blazer had fallen off one slim shoulder and her hip-hugging office skirt had ridden up her firm thighs until the lacy hem of her white panties was edging out from under the bunched garment. Both the lookalike's hands were roaming and caressing her stunning figure as she groaned and nodded to the next pair flanking the red runway.

"Summa Humani is popular with sexual extremists enamoured with the human form." Heather gasped as Not-Jennifer divested her of the offending jacket and buried her perfect face in the nape of the gorgeous redhead's throat. "Every conceivable body-specific fetish taken to new heights and only achievable through advanced Haardaxian bio-engineering."

Nathan and Jennifer turned, now expectant of a showroom display of exhibitionism.

“That’s right you Natty pounder, grab my Jenny nipples, I want you to fucking ruin them!” The violently aggressive Not-Jennifer screamed as she bucked astride her partner's hips, riding him like a deranged cowgirl down into the floor as he mauled her perfect bouncing tits from beneath with his strong hands. “Try and tear them off, you glorious stud. I fucking dare you.”

Not far from them and off to one side the cat-alien hybrid Nathan had plant-girl Jennifer bent over one of the short podiums as it licked and lapped at her nectar dripping flower-pussy from behind. Its long, rough feline tongue made the soft alluring creature squeal and moan in a high melodic voice and wriggle its luscious ass back into its partner's whiskered face.

What drew Jennifer’s eye was the next pair of duplicates stepping onto the red carpet. Like the couple before their bodies morphed and distended as they moved but not with florid or bestial alterations. She gasped and her fondling hand took a **** grip on Nathan’s ironclad cock through his bodysuit.

This was it. This was why they were here.

Her gaze was locked on Not-Nathan as he marched purposefully towards his Jennifer. He was growing whole inches in height with each manly stride, but his gains were not simply limited to height though but also length and girth.

Heather had been right when she complimented the true Nathan's proud package. He boasted blessings few other human men could hope to measure up to and was a seasoned lover but Jennifer held a deeply secret fantasy.

She wanted her man to be huge.

Even Nathan, extremely well traveled and open minded as he was, had been mildly startled when she revealed her personal collection of custom designed feminine pleasure aids to him. Many and varied as they were in form and function, the toys all had one thing in common.

They were all inhumanly large in almost every dimension.

Jennifer's prurient preferences in holovid stimulation was heavily skewed towards interspecies copulation. She wasn't honestly attracted to the hulking, scaly bodies of the Druzzian males or the slab-like physiques of the aquatic Tarithians. But the way their immense alien genitalia stretched and distended the throats, cunts and ass-holes of their human female playmates thrilled and fascinated Jennifer to toe-curling climaxes without fail.

So she was thankful for Nathan's steadying grip on her tight derriere when his obscenely hung copy finally came to stand with its similarly over-endowed partner. Otherwise Jennifer's knees might have given out in lustful excitement at the beautifully brutal appendage stiffening to gargantuan enormity before them.

“I believe the saying is; third time's the charm?” Heather cooed softly, gracefully detaching herself from the replica lovers. The two barely registered the Haardaxians departure, turning their burning passion on each other in a hot, hungry display of long wet kisses and groping grasping hands. “I note that while the male has caught your attention the female has not garnered the same regard.”

It wasn’t a question and Jennifer only glanced at her own wildly transformed mirror-image before dismissing it. Huge gravity-defying tits as large as her head, a tinyfied waist that even her own dainty hands could close around, a spread of hips and ass a mile wide and thick supple thighs… meh, it was an outlandish caricature of feminine sexuality that didn’t really interest her.

“No, as we said earlier. I am the one who will be undergoing the procedure, not Jennifer. She is already as perfect as anyone could have made her.”

One look up at Nathan revealed that his own limited interest in the over-sexualized creation was bordering on the clinical and far from aroused. She loved him so much, more so in the moment knowing he was here to meet her size-queen needs, outrageous though they might be.

“Well said, Nathan. Your love for each other is clear and here on Haardaxia such devotion is prized above all else.” Heather crooned, dismissing the Not-Jennifer with a wave of her hand before falling to her knees before the gigantified version of the man. “Are you satisfied with the proportions you see before you? The increase in physical build and muscle mass is easy to accommodate but I rather think that… this is where the lion's share of your interest lies.”

Without hesitation, Heather reached up and began smoothly stroking the monstrous hard cock swaying like a tree-branch in the air, inches away from her exquisite smiling face. Without really thinking about it, Jennifer began to mimic the woman's hypnotic gliding hand motions on her own Nathan’s throbbing bulge.

“Y-yes… I mean, yes, it is. We would like Nathan… my Nathan to be larger when fully erect.” Jennifer stumbled a little with her words. Something that never happened but to be so close to her deepest fantasy made flesh was messing with her mental equilibrium like nothing else could. “So big, long and thick…"

Her mouth watered when Heather shot her a coy wink and leaned in to lash her moist pink tongue over the enraged head of Not-Nathan massive tool as though it were an ice-cream cone. The copy that resembled Jennifer’s fiance grunted and grabbed a fistful of the kneeling woman’s crimson locks and began guiding her movements as she began eagerly licking and kissing her way along its tremendous length.

“Nathan… mmmnph~... All I need is your consent to have… mmwah~... your genome to be altered…” Heather gasped out between hot lip-smacking tastes of the meaty member.

“You have it. Unequivocally.” Nathan stated firmly, never breaking his passionate gaze into Jennifer’s eyes as she frantically jerked him off through his cyber-wear clothing.

“Darling, thank you.” She whispered up at him, gnawing at her bottom lip. “I promise that I am going to make you so happy.”

They kissed and it was like they had only just met, with the fierce need to take each other for the first time. Jennifer pressed her tight, lean body into his side as his big hands laced through her glossy auburn hair and pulled her harder into his lips. Their tongues danced and Jennifer drank in his earthy taste, rich as Gemini coffee and twice as invigorating before he broke the kiss to smile lovingly down at her.

“You already do, you silly Jenny.”

Then Jennifer felt it, a gentle but insistent swelling of his already rock-hard erection in her rapidly pumping fist. Staring down in fascination she watched the sheer synth-fabric warp and distend as the stiff tissue in her palm bubbled and grew in both length and breadth.

"Oh Baby, don't stop. That feels really good." Nathan grunted, his eyes closed as he lost himself to the sinful sensation.

Jennifer gave Heather a questioning look and got a wicked smirk in return as the Haardaxian bombshell paused in her own enthusiastic cock worship to answer the unspoken inquiry.

"The genetic catalyst was introduced to your bodies in the form of Haardaxian candy and would have been rendered chemically inert if this meeting was deemed unsuccessful. Nano-transmitters in your cyber-wear bodysuits are guiding the change as we speak." She purred huskily, a thin line of spittle still connected her ruby lips to Not-Nathans twitching immensity. "Simply stop stimulating him when you have achieved your desired outcome."

With that said, Heather turned her pretty head and swallowed the thick bulbous head of the male doppel's monumental member with a muffled moan of delight. Soon her crimson tresses were bobbing as she avidly attempted to skull fuck herself on his massive tool accompanied with hot gurgling noises as Jennifer watched Heather **** his brutish size down her slender throat.

The surreal turn in events washed over Jennifer even as she continued to stroke her Nathan's expanding manhood. Around her, their various altered copies were heavily engaged with each other. Kissing and licking and fucking each other in a hedonistic bacchanal that would have made Nero blush.

The first combative couple had flipped until Not-Nathan had its shrieking Jennifer pinned to the carpet, her limber legs bent back over her head as he plowed her until the floor with furious pounding thrusts of his powerful hips.

Feline Nathan had mounted his florid partner from behind, clawed fingers digging into her soft hips as it pried her lush verdant cheeks apart to drive deeper into her flowery pussy. Each feral penetration was punctuated by songful sighs and small yipping cries from the rutting pair.

The remaining showroom models had come to life, their perfect bodies joining together along the length of the carpet. Kissing and caressing. Sucking and slurping. Humping and fucking in a lascivious parody of the Federated Alliances favourite couple's lurid love life. The sights and smells stoked Jennifer's deepest desires as she drank in the endless possibilities of what could have been.

Most of all she kept coming back to Heather, the Haardaxian knock-out gagging and gargling on her Not-Nathan’s terrific tumescence. Jennifer’s eyes were riveted on the bulging rippling flesh of her tiny throat as the obvious outline of the duplicates mountainous cock battered its way down between the young woman’s clavicles.

If Jennifer had bothered to wear any panties on this excursion, they would have been drenched by her excited juices. As it was, the Synth-fabric seemed to wick away the moisture of her trembling cunt.

"Jennifer Baby… I'm getting close."

She came back to herself with a gasp at Nathan’s deep rumble of warning. Looking up at him, Jennifer discovered her own hands had been far from indolent. Pumping and teasing him constantly as she lost herself in the pornographic performances surrounding her like a salacious sideshow of carnal cavorts.

She was perched on his hip, her sleek thighs grinding together as she practically dangled off his broad shoulder. He was so tall all of a sudden, the top of her own pretty head barely reached his collarbone and his straining jerking member was of a size with her own forearm.

"Ooooh~ Nathan.” She breathed reverently, finally pulling her fondling hands away to cover her own gaping mouth.

Nathan groaned at the loss of her warm loving touch and finally opened his eyes. Looking down at himself, he paused then that damn half-smirk, half-grin cracked his handsome features as he pulled her tight against him and planted a kiss on the top of her head.

“Is that what you wanted, Baby?” He asked, with a throaty chuckle. “Is it big enough for you now?”

Jennifer wanted to sob tears of ecstatic joy but nodded instead. “Oh, my Love. It’s perfect. You’re perfect. I love you so much.”

Then, without waiting or asking permission, she reached up and touched first the stud at the collar of his cyber-wear bodysuit and then her own. The fabric billowed out loosely then dropped away, puddling around their bare feet. Both of her hands dropped to his stupendous shaft, running up and down its magnitude as she tried to touch every glorious inch of it.

“It’s so amazing, my Beloved. It’s so thick and unyielding but the skin is still so soft.” Jennifer babbled, her eyes thirstily drinking in every groove and vein of his preposterous protuberance. “I love how hard and hot to the touch it is…”

“I think I get it.” Nathan laughed and bent down to warmly kiss her again. “You really like my new dick.”

“No, you stupid Natty.” Jennifer’s rush of words ended in a ravenous growl and her manicured fingers curled up into small fists. “I love your new dick. Now be a good Natty pounder and shove that fat monster cock inside of me, right now.”

Grabbing his pulsing enormity in both hands (because it took two hands to have any shred of hope of wrangling the goliath love muscle) Jennifer dragged Nathan to the ground on top of her. In her horny haste she had misjudged his new size, both in height and endowment and ended up flat on her back with his huge engorged tip slapping down into the valley of her perky pillowy cleavage before his own collapsing body-weight drove it up that soft canyon to upper-cut Jennifer in her small chin.

“Oof! Whoa… I felt that, Baby. Are you alright?” Nathan asked, trying to push himself off her.

Was she alright? Jennifer wanted to cackle as she blinked stars out of her vision. Her man had almost knocked her out with his big swinging mega-dick, she was better than simply alright. She squirmed eagerly beneath his crushing weight, sandwiching his phenomenal girth between her brilliant perfect breasts and hungrily vacuumed his raging crown into the cupid's bow of her pouty lips.

"Oh Jennifer… oh faaark~!"

Her lips were drawn thin and her jaw creaked as fought valiantly to take in his whole apple-sized knob. Jennifer's moist tongue swirled, lathering and tasting his turgid tip, milking a heavy bead of pearly precum to bath her small mouth in his manly flavor.

Her frantic hands gripped her diamond hard nipples like tiny handles to roll and mash her buoyant tit-flesh around his rocky width, arching her spine like a drawn bow up into his rugged heat and savoring the feel of his epic throbbing man-meat against her flawless skin.

"Gah! Do you like that, you Natty scum?" She teased hotly, coming off his **** uber-cock for a much needed breath of fresh oxygen. "Do you like the feeling of this priceless Jenny body wrapped around your giant Natty dick?"

Despite the challenging dirty talk, Jennifer's thrilling cunt was soaked. She could feel Nathan's racing heartbeat in every twitch and throb of his gargantuan hardness and could hear him panting in a **** state of blazing arousal to match her own. She almost wanted crow in elation when he bent low to grab a fistful of her long autumn tresses and roughly yanked her head back to stare up into his dark domineering gaze.

"I fucking love your perfect Jenny body." Nathan growled, before smashing his lips in hers for a quick but torrid kiss. "I'm going to ruin this sexy Jenny body of yours for any other man."

Then he was sliding down Jennifer, his incredible heft dragging down her trim torso until Nathan's muscular hips were flush with hers measuring his lewd length over her smooth flat tummy, all the way up to her sternum.

"Do you see that, Baby? Do you see how far it reaches?" He asked in a gravelly tone, looking down at her writhing prettily beneath him. "That's how deep it's going to be inside you. Stirring up your insides."

"Yes, fuck yes…" Jennifer whimpered needily. "Do it… mess up your perfect Jenny wife. Fuck me with that massive cock, you dirty Natty pounder!"

Nathan had to pull back an unreal distance to maneuver his bulging tip towards her sopping entrance. Jennifer gasped as he slowly parted her fleshy folds, stretching her pussy lips until they formed a skin-tight seal around the top of his impossibly girthy shaft and made her pelvis ache deliciously.

"By the stars, Baby. You are so damn tight…" Nathan groaned, pulling back a fraction and drawing out more of her juices to lubricate his jutting length.

"No, my Love. You're just fucking huge!" Jennifer gasped and jerked her taut ass up off to the floor to **** him back into her.

A few more cunt-crushing inches slid into Jennifer and she squealed as her wet channel was filled to capacity even as Nathan pushed in further. Her peerless designer body bucked and flailed as he began to thrust, slowly at first, gaining more ground within her tortured twat with each stretching stroke.

Jennifer was literally built from the cellular level up to be strong, flexible and resilient far past any natural human standard. She had trained herself on her exceptional range of mammoth-sized sex-toys to take far more than any earth-born woman realistically should but Nathan was quickly taxing even her superior limits.

He was titanic in proportion, filling her fit to bursting and Jennifer loved it.

“So f-full… so g-good…” She huffed, struggling to breath as each hammering blow knocked the wind out of her.

“I’m almost all the way in.” Nathan panted, “Look at that sweet Jenny body stuffed full of my big Natty dick.”

Jennifer did look and almost unraveled at the sight. Her immaculately lean, svelte belly was distended with an obvious outline of his humongous man-meat pushing up from under her supple flawless flesh. She ran her soft hands down past her swaying cleavage to rest them on the bulge like a proud expectant mother after feeling her baby kick.

“I see it, Beloved. Now do it…” Jennifer crooned, happy tears glistening on her blemishless cheeks.”Finish filling this tight Jenny pussy and make it yours forever.”

Nathan thrust so deep inside Jennifer that he was crushing her g-spot, riding it as he bottomed out, ramming into the back of her cervix. Her gigantic fiance was filling and stretching her so full that her genetically fortified internals were shifting to accommodate his unfeasible dimensions. Her handsome lover was plumbing hither-unknown untouched depths and wrecking her completely.

It was divine agony, her darkest most secret wish fulfilled and it was with the only man she would ever accept as her equal.

Jennifer reveled in Nathan's rough handling of her utterly breakable body. He crashed into her time and time again, pulling on her long silky hair, mauling her perfect perky tits, biting at her faultless flesh, marking and owning her completely.

“Fuck, fuck, faaark~!” He roared, using a bruising grip on her slender shoulders to hold her in place as he humped and used her pristine body like a cheap fucktoy to get himself off.

“Yes, Nathan. Fuck yes, cum in my hot Jenny pussy!” She wailed, needing to feel him dump a heavy load in her screaming squirting cunt. “Fill me all the way up, you magnificent Natty stud!”

Her gorgeous head was bouncing like a bobble from the brutal pounding he was giving her. Her superb full tits swaying in small circles and clapping together in time with the slapping of their joining flesh. Heat seemed to pour off his heaving body, bathing her and filling her olfactory with his manly musk.

All the while she pressed down on the prominent bulge in her trim tummy. Working him through her own warped flesh. Feeling him move within her thin frame from the outside in.

Then… bliss.

Jennifer sang out in ecstasy and Nathan bellowed like a bull as he erupted inside of her. He pinned her beneath his towering bulk as she thrashed on the soiled carpet, stuck like a pig on his jerking fountaining cock as he fired great volleys of his hot Natty spunk inside of her.

“That’s it, my Love. Give me all of it.” She pleaded softly, locking his big hazel eyes with her own and cupping his perspiring face in her gentle hands. “Give your Jenny wife-to-be every drop you have.”

His gaze was distant, almost shocked as he continued to deliver his absurdly hot and heavy load into her swelling baby-belly for what felt like a full minute, before eventually he came back to her. She ground her sleek hips back onto his spasming magnitude, milking him for every drop as he lowered his head to hers until their foreheads pressed together.

“Oh Baby, my darling Jenny…” He rumbled hoarsely and she loved how deep his voice got after they made such passionate love. “Was that everything you wanted it to be? It wasn’t too much?”

“It was perfect. Everything I could have dreamed for and more, my sweet wonderful Natty.” She cooed and kissed him warmly on the lips. “You were amazing. Thank you for indulging your silly little Jenny.”

They stayed there, locked in a brief eternity together. Nathan was still buried inside her placated pussy, holding her tight against his strong rugged body as she caught her breath and rested her head against his bare burly chest.

“Look at what you did to me though.” She giggled, guiding his hands down to the rounded pooch in her usually flat stomach. “Do you like my new look?”

“I love it,” He said, chortling along with her as his hands ran over her belly bulge. “Though we might need to move the wedding date up a few months. I’m not sure your contraceptives will handle that sort of load.”

“I can’t wait to find out…” Jennifer began then stopped at the soft sound of clapping nearby.

They turned as one to see Heather standing a few feet away. She was beaming happily and politely applauding them, her smart skirt suit back in place and her pretty face was spotless as though she had never been a part of the prurient proceedings at all.

She was also alone. The Nathan and Jennifer clones, the pedestals they had been displayed on, everything but the red carpet had vanished. Suddenly it was just the three of them alone in the empty cavernous space.

“You were both fantastic, thank you sooo~ much for sharing your passion and energy with us today.” The mysterious redhead gushed, almost dancing in place. “So much love, such devotion. Are you both satisfied with the outcome of our consultation?”

Satisfied? Jenny was certain that she wasn’t going to be able to walk for at least a day or two. So… yes, she was very satisfied.

Nathan must have read it in her smug expression because he answered for both of them.

"Yes, I dare say we are." He said, lifting Jennifer in his arms as he climbed to his feet. The movement caused his softening member to slip out of her bloated insides and a small cascade of their combined juices splattered into a large, pungent puddle at his feet. "Uuuh… sorry about the mess."

"It's not a bother, Nathan." Heather said with a gleam in her emerald eyes as she licked her cherry lips. "I will… take care of it after your departure."

"Fine, fine. So that is it then?" Nathan asked, looking about as Jennifer snuggled in happily under his chin.

"Yes, I believe this concludes our business and time together." Heather said with a small regretful smile and gestured towards the large double doors they had entered through. "On behalf of the Haardaxian people, I thank you for your visit and extend to you our friendliest invitation to visit again. Just so long as you abide by the terms of our agreement…"

"Ha! With the prices you charge…" Nathan began to retort then paused, looking down at himself. "Well, never say never."

"A fine sentiment, Nathan." Heather giggled. "We Haardaxians have a traditional farewell. May the many paths we each journey intersect once again."

Jennifer thought that sounded rather nice, smiling sleepily as her big strong Nathan carried her to the exit. Heather held the door open for them before continuing.

"However in the case of you and the lovely Jennifer, I think I prefer an old human maxim." She shot Jennifer a saucy wink as she was carried past. "See you again soon."

Then the doors clicked shut and Heather was gone.

"Well, that was quite an encounter." Nathan commented wryly as he walked them both across the small foyer to the open airlock. "Are you still okay, Baby?"

Jennifer had never felt better. Sure, she was sore, so incredibly sore but it was a good kind of soreness and nothing that thirty minutes in the ship's auto-medico wouldn't fix.

Until then maybe, just maybe…

"Mmmhmmm… I was just thinking, my Love." She said coyly.

"Tell me."

"Maybe once we are underway, you could try shoving all that huge Natty cock down my tight little Jenny throat?"

Nathan let out a mock growl and hugged her tighter to him as he ducked through the airlock. He was just so big now.

"Anything for you, Baby. You know that."

Jennifer sighed in contentment, she loved him so much.

She couldn’t wait to feel him fucking her up again.

The End.
