In the far future of mankind, interplanetary colonisation was well underway: the stars shone with the glittering beacons of a hundred human worlds, from the miraculous comfort of the Terran standard planets to the hundred variations of difficulty, danger and dysfunction that could result from the smallest of changes. Worlds with high levels of chlorine in the atmosphere, others just a bit deeper or a bit further out from the gravity well, others with lush vegetation that could produce wondrous cures or the vilest of poisons.

The solution had been not to change these planets through expensive terraforming, or look ever and ever outwards, but to change humanity, bit by bit. Gene therapy, biological component engineering, behavioural programming... all these tools served to make us at home among the myriad stars, making us by degrees, more and less than what we were.

This is a story of two people who managed to find happiness; happiness in a world where humanity is more of a cultural agreement than what we know now: a species bound by blood and love and society.

The dating grid node had been recommended to him by three or four old acquaintances, a way of meeting people who were "plus normal" as the advertising put it. The pleasure city of Euphoria was the hub of this special interest sexual fetish, a den of vice so involuted and corrupt that it had acquired the laid back charm of a mature courtesan. Every service route, secluded corner and gaudy bar exuded the kind of relaxed, unaffected atmosphere of an opium cafe, where love and lust could blossom and die in their own time, where the frantic hustle of crime was replaced by the slow waltz of seduction. For him however, it was simply home for now: a place where the freaks met the freakish and being baseline human was rare in the extreme.

So here he was, sitting in a quiet little booth in a place that served only the most ridiculously coloured cocktails the galaxy could offer. As he sat waiting, looking at the peculiarly pinky green liquid in his glass he felt the presence of another person between him and the low interior lighting and looked up.

Into the face of a goddess.

The woman was easily a head, perhaps a head and half taller than the rangy waiter who was making his way over to the table, putting her somewhere about seven, maybe seven and a half feet tall. But to say she was a big girl would be to miss the point rather spectacularly; if she was taller than the waiter by a little bit, she was certainly more than a little bit more massive than him, perhaps three or four times the server's bodyweight and all of that unbelievable muscle.

There was something about her, a proportion, a collection of dangerous curves that was enough to let him know she was all woman, but it was her physique, her bearing and her glorious physical conditioning that really set alight a fire deep inside of him. On his homeworld, some tribes people were
amazonian, tall or strong or a combination of both and in his hunting days it had excited him to meet and add these women to his harem, but this woman was more than that, much much more.

She smiled down at him, eyes twinkling at his expression, her face a symphony of graceful muscularity and beguiling feminine wiles. Dark, wild curls surrounded her features like a silken cloud, framing a gently oval shaped face, her bronzed skin caressing high, wide cheekbones and a smooth jawline. Her purple eyeshadow was painted seductively around a pair of almond shaped eyes, luminous dark irises glimmering softly in the club lighting, the creases around her eyes speaking of many happy smiles as she grinned pleasantly, full, lush lips shining purple again and parting to show white, perfect teeth.

He found his voice in time to save his manners, offering, "Er, I'm so sorry; please have a seat! I didn't know tha- er, I should ha- hrmpph..." His thoughts tumbled out one after the other and he saw as he spoke that her smile looked a little strained now, eyes watchful but still good humoured. Gripping the table, as if the physical act would steady his thoughts he collected himself and said plainly, "You really are a very gorgeous woman... you've put me at a loss for things to say, I'm afraid!"

Her smile in return was like a binary sunrise, lighting his heart and his loins something chronic... he could almost feel the force of his attraction, a tingle all over his body that bathed him like a dip in a tropical plunge pool. He put his hand across the table, in offer of handshake and said, "Just so you know I'm not here by accident; I'm Marcus, it's lovely to meet you," he stumbled briefly over the login name
she'd chosen, "GRwngGRRL001...?"

In return, she met his hand with her own and shook it once, gently, fingers lingering over his before she took her hand back, "Just call me Lisa, Marcus, it's probably easier for both of us!"

Her voice when it met Marcus' ears was like the sweetest, most mellow golden honey, the words raising the hairs on the back of his neck like a lover's kiss and he felt himself shiver from the top of his head to the tips of his toes. Marcus swallowed audibly and gazed upon her, enraptured, "Oh my dear Lord!" he whispered hoarsely.

Her delighted laughter rang out across the club like a chime, the sound like a blanket wrapping Marcus in it's crystalline embrace...

---

An hour or two later they were strolling down the corniche in the cool, climate controlled air of the arcology, an arm easily twice the mass of either of his legs, if not both together, slung across Marcus' shoulders like a warm, muscular feather boa. It was a strange sensation for him, something that should be practically half his bodyweight resting comfortably across his back; he felt that she must have incredible control to be able to do that. His hand moved up and briefly squeezed hers in appreciation, before instinctively stroking her power packed arm and wrist, drawing out a satisfied hum from his companion.

His fingers briefly felt a series of tiny bumps under her wrist, each bump a little patch of shiny scar tissue and her felt her tense a little bit, before her massive form leaned in and she whispered, "Don't worry darling, it's not what you think." She kissed his ear softly and chuckled, leaving him for some while unable to think anything much at all.

The meeting/date had gone very well and it seemed that while they didn't share a lot of interests, they found each other interesting and were all too happy to spend some time getting to know each other. Marcus had eventually recovered his wits a bit and had showered her in compliments, eliciting many pleased smiles and an almost feline level of satisfaction. Lisa had told him about the great length of the wait for someone who could not only deal with her physique, but revel in it, enjoy it the way she very obviously did.

He looked across at her as they walked and knew that she very much enjoyed flaunting her body. Her dress was nothing short of scandalous: a straining micro mini that was stretched almost to breaking point across her expansive chest and the tops of her massive thighs. There was only one shoulder strap, leaving him with an unobstructed view of her pumpkin sized shoulders, allowing him to enjoy the sight of ten people's worth of muscle jostling for space in one place and her boulder shattering thighs lifting the hem of her dress as she walked, brazenly flaunting a white candyfloss thong that was almost swallowed up by the power packed, striated muscle.

Marcus could barely contain himself as she walked alongside him and strutted her stuff and was certainly shocked when she reached across and grasped his hand gently, moving it to rest on her powerful glutes. A playful twitch of her muscle nearly jogged his hand from its perch, but her saucy wink let him know that what she really wanted was for him to keep it there or thereabouts. They walked on then, happy and contented and for a few minutes they shared a charged and somewhat mutually appreciative silence.

But Marcus wasn't just a baseline human, he had come, some years ago admittedly, from the humid harem jungles of Zeitun V and this woman was stirring up some fairly powerful feelings inside of him. He could feel the glands at the base of his neck kick into life and soon he was wafting a seductive pheromonal perfume across the gently breezy climate controlled air of Euphoria. In an echo of the old mating hunts of yesteryear he could feel his libido rise, overwhelming the shy, retiring persona of a sin city drone and slowly letting the personality of a rapacious sexual predator bleed through.

A hand on Lisa's ass was soon two as he gently steered her round into his arms, feeling her skin slowly heating up to match his, kissing and worshipping the bottom half of her mountainous pecs as she ground into him like a great, warm goddess. His fingers deftly circumnavigated the pathetic little panties, dipping into her power packed gluteal cleft, sliding fingertips over her tiny, puckered anus to dip into her wet, slick little pussy, feeling incredible tightness surround the end of his digit. Marcus could feel every shudder through her body as she gave into the sensation, he could feel her heaving chest lifting and dropping her massive breasts, the huge implants swaying pendulously atop her granite boulder pecs.

Lisa nibbled and licked at his ear, bending over, turning his face up to hers for an incindiary kiss, her
lush lips pressed into his, tongues swirling, tasting and savouring each other, her breath hot between
them as her hips ground against his fingers and bucked upward in small paroxysms of passion. He felt
her hands settle on his ass in return, massaging and kneading his butt. Her thrusting hips and his wet
fingers had achieved a steady rhythm, her massive body flexing and tensing as she rode his hand, the
smell of her warm, minty breath hot and moist in his nostrils as she ravished his lips with her own, her
gasps little notes of pure pleasure in the empty silence of this back street.

Taking a hand off his ass, Lisa reached out behind her to steady herself, grabbing a railing and using the oppotunity to wrap a gargantuan leg around Marcus, her huge thigh radiating heat like a sexual fire as she bucked against his talented hand. Sighing, hissing breaths from the muscular woman gave rise to stuttering gasps as the heat rose in Lisa, colour flushing her enormous chest, gasps mellowing out to lusty moans as her orgasm neared. Every sucking breath drew in more and more of Marcus' powerful pheromones, redoubling her sexual passion and every sweet sound she made drove him on to greater lust. His hands roved over a thigh thicker than his entire torso hugging his body like the crook of some great tree branch and with a groan he gave into his desires, the time for teasing over, frantically thrusting his fingers home, hooking them back to find her G-spot.

Lisa's eyes popped open and her face slowly tilted back, teeth clenched together hard, not breathing as the powerful orgasm rolled over her, her neck red and swollen with lust and power, the veins standing out like thick cords of hempen rope. Marcus' fingers were trapped in the velvet vice of her thrumming pussy as the waves of pleasure rolled over her, her powerful body shaking in a tight, electric tremor of red hot passion. For some long seconds she stood in this paroxysm of lust, eventually drawing a long hissing breath and screaming into her clenched teeth, not a whimpering whine of soft girlishness, but the triumphant mating howl of some alpha predator finding satiation.

Panther dark eyes looked down at Marcus after a certain long while, the long ragged breaths evening out now and he could only shiver as Lisa intoned one lascivious word, an edge of hunger in her voice, "More!"

---

His fingers were soaking wet and slippery, yet clamped unyieldingly by the velvet walls of Lisa's pussy as she came, his hand small against the expanse of her huge bare legs and powerful ass, the other hand lost against the vastness of a single powerful thigh. She had both her hands planted against the wall, standing with her back to Marcus, butt thrust out like an invitation and legs spread in the dappled light of the service route by her apartment building. He could see the lines of gouging and cracking in the wall of the building where here hands had raked the finish, could feel the awesome heat and power of her as she shuddered through another orgasm.

He couldn't see her face, but her moan was a low, passionate thing of animal instinct as she rode out her carnal lusts, hips swaying and twisting and grinding slowly, letting her fingers squirm and tease and penetrate further inside her. Her magnificent legs swelled and flexed and pumped as she used all the power and control of her muscles to make the slightest shifting movements, tiny adjustments but done with all the unstoppability of a mass driver. Marcus pushed and stroked and stimulated with his fingers as her full, muscular glutes bunched and flexed, gliding her hips back and forth, back and forth onto his hands. Her gasps had the stuttering, choked sound of someone at the edge of great pleasure, but she still had the wherewithal to reach between her mighty thighs and softly, deftly, slide a third finger of his inside her dripping pussy.

Her cry had all the hallmarks of lust and disbelief and joy that he had come to know over the last intimate hour they had spent, kissing and loving and enjoying each other's nearness on the way back from the bar. Her feminine juices had slicked her inner thighs like a glaze, and knowing he risked getting his head crushed, he leaned into her spread legs and inhaled the musk like a perfume, slowly lapping at and licking the musky fluids from her silky boulder thighs. His tongue delighted in the taste of her and the texture of intricate web of blood vessels and tiny, ultra defined muscles and muscle fibres that made up the entrance to her juicy sex.

He felt her tense and start to cum, even before that desperate, choked gurgle of ecstasy squirmed out from between her clenched teeth and he only just had the presence of mind to jerk his head back before her ass and thighs exploded into a wall of tense muscle. His wrist was saved by the proudness and contour of her exquisite vagina, fingers held in a tight grip as her body went into the spasms of pleasure once more, her gasps from the previous orgasm eclipsed by the strangled moans she was making now, as this release joined with and was reinforced by the sensations of her earlier cum.

Marcus had been acutely aware of his own arousal for many many minutes now, but was able to keep it roughly in check as the vestiges of his training reasserted themselves. He knew it simply would not do to reach a state of full arousal in public in this city... his kind had a bad enough reputation anyway without causing mass panic. But now he could feel the blood flow creeping ever onwards into his genitals, the sheer visceral sexiness and power of his partner overwhelming the mental exercises he was practicing, filling his mind with the sheer presence of Lisa.

Luckily, she had more or less the same idea he had, gripping his wrist gently but firmly and dragging his fingers out of her vagina, turning, with her mini skirt still hiked sluttily over her ass, the folds resting on her childlike glutes. With long strides, not stopping to cover her sex, or her sexy ass, Lisa marched around to the front of the building a high flush across her chest and in her cheeks leading Marcus by the hand as we walked. With a girlish little giggle, incongruous in a woman so massive and vigorous, she stopped and lifted a leg, sliding her soaked, rumpled panties to the floor and stepping out of them, looking back at Marcus and smiling, twirling the undergarment playfully.

Bare, exposed from the belly button downwards but for a pair of high heels, she walked into the lobby of her apartment building, casually tossing her soaked underpants onto the steel head of the robo-concierge, the panties looking tiny and ephemeral now that they weren't stretched tight around her massive waist, muffling the automated greeting of the security machine. A few more footsteps took them both through the atrium and to the lift lobby, where the air between them positively crackled with sexual tension, the only sounds the cool electronic ping of the lift call button and their heavy breathing.

With a tinkle of musical notes the lift arrived and the doors opened, revealing a young man frantically tapping on a datapad, dressed in the livery of a fast food delivery chain and preoccupied by his work. The first he knew of Lisa was when she grabbed his wrist and shoved his hand between her slick thighs, the stylus falling to the floor with a tick, his protests smothered quickly by her powerful, insistent kiss. With her other hand she picked him up by his jacket and turned to put him in the lift lobby, bending down and flicking the stylus into the lobby after him. Marcus quickly joined her in the lift and she pressed the button for her floor.

The last thing the delivery boy saw as the doors closed was a muscular goddess, dress hitched above her waist, sucking on her finger and looking him in the eye as she masturbated herself with her other hand, exuding raw lust. He saw her lips move and heard Marcus' chuckle before he could register what she had said, but as he left it echoed round his head.

"What do you think of *that* for a tip?"

---

As soon as the reassuringly heavy door of Lisa's apartment clunked shut, Marcus felt himself relax a bit, watching her sashay into the bluish gloom of the unlit room, the moisture on her inner thighs visible as a sheen, a suggestion of shininess. Her footsteps receded away into the darkness and he lost her for a little while as she stepped into a very shadowed corner of the room. Music started to waft softly out of hidden speakers, a tinkling little chime the only indication that it was at her initiation. The sounds were melodic and pleasant but not distracting... obviously the only art appreciation Marcus was supposed to indulge in was her sculpted body.

Uncomfortably, he adjusted the crotch of his loose trousers and felt his manhood engorge slightly, a constriction to blood flow eased for now, the bulge at his waist growing noticeable now, pressing the fabric outwards in a thick hump. His attentions returned to the room as he heard Lisa breeze past once more, this time with different shadows painting her body the sound of her footsteps muffled a bit by thick carpet. As she grinned at him, her teeth gleaming silver blue briefly in the semi dark, he noticed what was wrong about these new shadows and smiled himself... her tiny little dress was gone.

Lisa disappeared into the gloom again and some seconds later a soft, orangey light came on, lighting a doorway further away than he expected, bringing the apartment to life in a still image of sweeps, curves and angles: orange highlights against the evening light. Lisa was stood in the doorway like a gatekeeper, her body black against the light from behind her, the glow caressing rolling, powerful bulges of muscle, a corona playing around the wet downy hair over her pussy. In the moments he stood silently and drank her in again, member hardening further she raised a hand and crooked a finger, seductive and demanding.

Marcus needed no further encouragement, unbuttoning his trousers to pull his shirt off, kicking off his shoes as he hopped toward her bedroom, struggling out of his clothes. By the time he arrived at the door he was down to a pair of overmatched underpants and once sock which he was tugging off with great haste. Looking up he felt himself stop breathing, seeing Lisa on the bed, looking over shoulder as she did a slow one handed press-up on the soft mattress, the fingers of her free hand buried in her snatch, thumb caressing and rubbing the thick nub of her clitoris. He saw her bite her lip and moan in desire as she looked down at his crotch, the only other source of movement in the room, as a huge lump was straining to erupt from the confines of his jockey shorts, the stitches popping one by one.

"Oooohh!" she purred, smiling wickedly, "you're one of *them*! Mmmm, how kinky..."

The legacy of human genetic manipulation has seen many triumphs, both technical and moral, but has also exhibited a dark and twisted underbelly characterised by freakish anomalies, the engineering of "super-races" and a legacy of sexually deviant proclivities. The world of Zeitun V was one of these scientific backwaters, a private colony planet run by scientists made rich on the spoils of gene therapies and task-oriented gene manipulations.

These men and women had let their imaginations run wild, using the human genome as their canvas, splicing
in DNA from Earth flora and fauna and indigenous organisms found on the jungle world. Selective breeding practices were implemented by some and the creation of artificial genes was worked on by others, bending the laws of nature and science. Each lab had a different approach, different specialities and fetishes and so was born a melting pot geneculture of the weird, the wonderful and the downright strange. Women with male genitalia, anthropomorphs, humans with immense secondary sexual characteristics and those with more subtle changes, hidden from the eye, or sets of eyes as the case may be...

And then, one by one, the scientists died. Not violently, not accidentally, but slowly and of old age. And with them died the order that had kept things generally heading in the right direction. The population exploded in four generations, spreading from the equatorial belt to the polar extremes, from the highest mountains to the most abyssal sea trenches. Technology became the hallmark of the rich even as civilisation decayed. Within one hundred years of the death of the last human scientist the world was a densely tribal, tumultuous and dangerous place to live.

Tribes with different genetic traits sent out raiding parties to accrue mating harems, adding depth to the gene pools, selecting positive traits, watching as genetic anomalies merged and changed and evolved into new and different forms. In the present day large nation states were slowly coalescing out of the soup of tribes and rogue bands, following in the wake of a Uniter, a person who had turned the Deep Green into a personal fief, conquering and subjugating other lands, using diplomacy and trade to achieve his aims. The world trembled under his growing power and the tides of fortune shifted into battle lines and national borders... war loomed.

And then, he was gone.

The states slowly fragmented again, to acquire different names, merchant leagues sprang into existence and for the first time in three centuries the tendrils of planetary civilisation began to knit together. The others in space soon grow to hear of the harem planet, home of sexual excess and orgiastic sex attacks and finally Zeitun V, the "Planet of Rape" according to intergalactic news, was a place on the map again.

---

Marcus dragged the material of his shorts down over his ass, cock sliding free to bob semi-hard in the cool air of the room. The shaft was covered in cable thick veins, a long, thick stalk of cock nearly longer than his forearms and not even hard yet. He was sweating lightly now, the heat in the core of his body reminiscent of all those frantic mating hunts, lightly dressed and ready to fuck anything that cross his path, to subjugate them. His nostrils flared as he caught Lisa's scent in the room and his cock jerked again, getting harder and longer by the second.

His reaction was different than usual though, a feeling of mating rut paired with a respect he had rarely felt with a naked woman in front of him. The sheer sensual power of her massiveness permated the air, overrode his harem instinct, left the sweet mix of arousal and fear deep inside him a pleasant tingle that seemed to wrap itself around his huge cock and low hanging testes. He licked his lips as he slowly walked over to his date, watching her eyes glued to his rod; she spread her legs and gyrated her hips lewdly from this one hand press-up, her fingers making the smallest, sexiest wet noises as they slipped in and out of her pussy.

Still holding herself up one-handed she dragged her soaking fingers out of her box and across her massive, ridged tummy, the glistening digits running over her boulder glutes until one found the tight brown pucker of her anus. Lisa giggled and licked her lips as she forced a finger deep inside, body tensing, bulging out to ridiculous proportions as she savoured the sensation.

Marcus grunted as he felt his cockhead slap into his chest, his mast fully erect now and looking like an angry, knotty instrument of sexual punishment. His movements were almost feral, wild as he raced over to the bed, Lisa tensing at the sudden change in Marcus' demeanour, only reassured by her own size and the soft sag of the mattress as the muscle struck man worked his way over between her legs to press the leaking tip of his dick against her slit. A shudder rode through Lisa as she felt the spongy flesh pressed into her sex, the glans so big that the top pressed against her anal probing finger and the bottom was rubbing her rosy, throbbing clit.

Marcus' body was covered in sweat and lean like a prize fighter, his thighs and waist a lot stronger looking and more developed than even Lisa realised, and she considered herself something of an expert in muscle. He grunted behind her as he rubbed the tip of his cock up and down her soaking slit, letting the head ride forward into her pussy a little bit with every stroke. She could feel his heat, but he seemed reticent, unwilling to skewer her, perhaps in need of a little encouragement.

Lisa moved slowly, the finger sliding out of her asshole, her hand sliding down to the bedsheet to join the one supporting her body weight, bulging with power. She felt the tip graze her entrance, once, twice and on the third pass, jerked her hips up and backward, feeling Marcus get jolted nearly off the bed, screaming as her vagina got stretched around his log of a cock, taking the head and an inch or two of shaft deep inside her. She could feel his hands hurriedly reach out to grip her hips, struggling to keep himself balanced, keening softly in time with her gasping breaths, his cock trapped in the prison of her pussy, every knotted inch inside her gripped in a velvet vice, stimulating her.

Changing his position, Marcus flexed powerfully, body tensing into a sculpture of chiselled muscle, driving his hips forwards. He could feel the heat in his face and the sweat on his body from the effort, but knew even as he thrust harder that Lisa was in control. She was moaning, high, quick sighs of pleasure and pain as her vagina was stretched farther than it had ever been, but even deep inside herself she could feel the warm glow that was so close to the satisfaction of a good pump, the countless years spent in the gym telling her endorphin fuelled brain that no pain, was no gain. Marcus slipped in further suddenly, eight inches of his almost inhuman erection ploughing into Lisa's centre before she arched her back and once more held him in her gripping tunnel.

His senses were sharper like this, his body shovelling hormones and adrenaline around his frame at an accelerated rate: he could feel the fine musculature inside Lisa's hole as it flexed and massaged every inch of his member, hear her squeaks slowly get a growling gravelly undertone as she began to work back into him, swivelling her hips and pushing back now. Her entire body was a mass of rolling muscle, the veins rising to prominence around her arms and waist as she pushed harder and harder back into her lover, the tanned skin looking like bronze body paint over an extravaganza of power. Marcus could only really concentrate on the sheer overload of this sexual experience, revelling in a sense of
her power that none of his previous partners had ever shown him, a novel route into sexual excess with this
dynamo of a muscle goddess. He felt her stomach muscles rippling as she moved her arms down to her waist, hands spread wide in support of her body, the veins in her biceps exploding into power cable relief as she
struggled to compensate for the odd balance of her bodyweight. She barely even grunted as she lifted her feet off the bed, concentrating on keeping stable as she hovered, effortlessly supported only on her hands, her torso anchored down via Marcus's huge, brutalising penis.

He froze, uncertain, not sure what she would do as she spread her legs into a full splits, impaled on him like the lewdest, biggest, most jacked gymnast ever seen. He marvelled as her leg muscles bunched into thick heavy slabs, as her tummy muscles tightened around his shaft, her gluteus muscles spreading and showing him her tight, wet anal bud once more. Lost in revelation, he saw her lower legs fold in like the lotus position, felt the soft pads on the soles of her feet touch his bottom and press into his flesh.

And then she pushed, hard.

It almost felt like the blood was being pushed out of his shaft as she pressed him into her with her feet, her muscles shaking now from working so hard in this kinky stress position, the walls of her slick, hot pussy still almost unyielding against the pressure of his penis. Marcus could only gasp as the gripping vice around his cock suddenly changed it's nature, Lisa's abs rippling now as her insanely developed inner muscles physically pulled his shaft inside her, her little shrill grunts a pained counterpoint to the awesome power of her pussy. The haze of lust thinned slightly the moment he heard that and he knew then that even this sucking penetration was hurting her, his huge cock uncomfortable for her unprepared box, but she was taking him anyway... and loving it.

A passenger for now in their lovemaking, Marcus let Lisa take the lead, feeling her inner muscles expel his meat now, her pressing feet not letting him slip out of her completely. He saw the muscles in her arms swell and flex and bunch into rocky striations as she pushed back at him, slowly setting up a rhythm, his mouth hanging open in awe as she exerted her massive strength. Her whole body was shining with sweat now, the blush of red heat shading her skin as this symphony of muscles drove their strange lovemaking. Even she couldn't hold out forever though and slowly lowered her chest to the bed, her arched back keeping her hips in the air as she panted into the pillow.

Unable to see her face, Marcus could only hear a ragged grunt before the pulsing walls of Lisa's pussy pulled him into her once again, his dick as hard as steel and tingling with the pending promise of orgasm, the sight in front of him goading him, almost forcing him ever closer to cumming hard into her. He could feel her muscles pulling harder and harder, watching as his hips got drawn in towards her powerful ass and he gasped as he felt the tip of his penis jam hard against Lisa's cervix, only six or so inches remaining outside her pussy. Marcus swore then, and loudly, as the sensations on his mutant cock doubled and then tripled, a throaty yell from underneath him and an explosion of writhing muscles and veins underneath Lisa's golden skin accompanied the pain as his head was mashed cruelly against her cervix, the pressure mounting with every second.

They screamed together as his titanic dick speared through the cervical opening and into Lisa's womb, his enhanced testicles jerking up hard as his orgasm began, his hands gripping her hips like a pair of vices, the whole length of his unnatural cock trapped inside her shaking mass. The veins on his neck stood out like cables as he yelled, feeling the copious semen rocket through his reproductive tract to jet out of his throbbing meat, the sensation of his cum pipe bloating under the pressure enough to make him grit his teeth. The first blast smacked loudly into the back of Lisa's womb, causing her to jerk her hips convulsively, her powerful form writhing and wriggling underneath him now as she gave into the tide of her orgasm, her legs snapping out straight and toes curled as she shuddered and shook through a titanic wave of pleasure, crying out lustily and looking ahead wide eyed.

The thick, sticky spunk squeezed back out around Marcus' shaft like a hydrant, the power of his abdominal muscles and the tightness of the seal enough to force the virile juices out from between them in a rush. The splattering gooey shots pounded against Lisa's sensitive womb for what seemed like eternity, the sheets turning into a soupy marsh at their joined waists as the enhanced reproductive systems inside Marcus' lean body went into overdrive.

Some minutes later, Marcus was sucking in huge lungfuls of air, slumped over the warm and massive body of his lover, listening to her satisfied purrs as the softening lump of his dick inside her set off tiny orgasmic aftershocks. Slowly, he rolled off of her and landed on his back, head near hers as he lay panting, the trunk of his red, abused cock sliding out of her with a slurp and thumping wetly onto the sheets between his legs. Her hand reached out and stroked his belly as she stretched over and kissed him on his cheek, a soft hum of pleasant satisfaction from her being all the sound in the room.

"Hmmm," she giggled, reaching underneath herself to stroke her own tummy, "I feel so full darling... I may have to keep you."

For his part Marcus could only smile exhaustedly and shake his head ruefully, returning the kiss gently and slumping, tired, back onto the bed.
