Introduction: An alien entity in search of a mate invades the home of a suburban couple.
 
On the last day of his life, Paul Greenstreet woke to the sound of his wife singing.

He rolled over in bed, pushing down the comforter and looking at her as she got dressed at the mirror. Early morning sun was streaming in and her perfect silhouette stood in a spotlight of golden rays.

She was busy fixing her hair. She had on the blue skirt and blue jacket over white blouse outfit that meant she was going away on business, and she was singing "Eight Days a Week", which meant she was in a good mood. She turned and smiled at him while fixing the diamond earrings that he had given her for their anniversary.

"Good morning sleepyhead."

Kim was thirty eight, five years older than Paul, but she was gorgeous enough to be the envy of women half her age, with pale blond hair, a perfect profile, buxom breasts, and a curvaceous body that still drove him wild even after all these years.

"Good morning," Paul said. "Look at you. The conference doesn't even start until tomorrow, aren't you a little overdressed for a daylong car trip?"

"Oh, I know. But I can't leave the house for one of these things unless I feel like I'm really prepared, and that means dressing my best. I guess it's a little silly, huh? The only person who's going to see it is the kid at the drive thru when I pick up lunch."

"That's not true, I'm seeing it. You look beautiful hon." He patted the spot on the comforter next to him. She sat down, stroking the back of his hand with her fingers.

"I know you're not happy about this Paul."

"I didn't say a word."

"You don't have to. You've been moping all week."

"I'm sorry hon. I know this trip is a big opportunity for you. I'm happy, really. It's just that two weeks is a long time. We haven't been apart for that long since we've been married."

"I know. It's just this once, I promise." She squeezed his hand. "Hey, you want to see what I didn't include in this outfit?"

"What do you mean 'didn't include'?"

She got up on her knees and lifted the hem of her skirt. "See? No panties." She smiled wickedly.

He whistled. "Gonna show that to the kid at the drive thru?"

"Nope, this part is just for you mister." She pulled the comforter down and swung her leg over his body, straddling him.

He ran his hands along the length of her legs, smoothing over her nylon stockings. "Careful babe. You just got put together, I don't want to ruin the ensemble before you head out the door."

She reached down, the tips of her lacquered nails trailing across his abdomen, sending tiny shivers through his body. "Don't worry, I'm a big time businesswoman now, and that means I remain immaculately coiffed no matter what."

"No matter what huh?"

"No matter what," she said, wrapping her hand around his morning erection and squeezing firmly.

As Kim Greenstreet stroked her husband's rigid cock in the palm of her hand, both of them preparing to indulge in one last spontaneous romp before parting, neither was aware that they were not alone. Something else was in that room with them, invisible and undetectable, but waiting and watching.

The strange presence stirred, awakened by the faint psychic ripples caused by their mutual arousal. Unbeknownst to the couple, inhuman eyes observed their every move, lurking in the shadows. The moment it became aware of them, their lives were altered forever.

Kim gripped Paul's shoulders, pinning him to the mattress, still smiling that special, naughty little smile of hers. "Now you just stay right there and relax. I'll take care of everything."

Paul felt a low throb of pulsing desire as he caught a glimpse of his wife's tight hairless pussy under the hem of her skirt. "I guess if you're the big time businesswoman now then that means you're the boss?"

"That's right," she said, as she gripped his swollen cock in one hand and guided it to her, "I'm the boss."

She teased him by pressing the tip against her and running it up and down the length of her slit, swiveling her hips back and forth, letting him feel her hot and wet, her outer lips swollen and dripping with desire. His shaft throbbed in her hand as she squeezed just below the tip, pressing it against her, letting it penetrate a little as she held herself over him. Paul gasped and grunted, hands gripping the bed sheets into knots as his entire body trembled with anticipation. .

Meanwhile, still unseen, the strange presence was taking in every detail of their interaction. It studied the curves of Kim's body, Paul's muscular physique, and the tiny panting breaths that each took. It detected the delicate flush on Kim's face, the tiny hairs standing up on Paul's arms, the heat of their bodies so close together, and most of all the intense, smoldering passion of each for the other.

Kim finally relented and, pushing down with her hips, guided him inside. She was hot and wet, the confines of her body rippling as he entered her. She pinned his shoulders and began to move on top of him, swiveling her hips. She meant to tease him further by starting slow, but soon she felt intense desire blaze inside of her, and she increased began riding him, grinding against him, indulging herself.

Kim licked her lips and moaned throatily as she pumped up and down. She had started fast and then only increased her pace, until she was in a wild frenzy, riding with reckless abandon, gasping and panting as she lifted herself and then dropped again and again, pounding him relentlessly.

Paul couldn’t help but admire her. She was right, she stayed immaculately coiffed no matter what. There wasn’t a single wrinkle in her business casual attire nor a strand of blond hair out of place even as she bounced up and down on him. Other than the throaty moans from her open mouth and the little pinched furrow in her brow that meant she was about to orgasm, everything about her looked ready for the boardroom instead of the bedroom.

He could tell by the way that her firm, voluptuous breasts bounced under her blouse that she hadn’t bothered to wear a bra with the outfit either. When she arched her back her hard, swollen nipples pressed against the white fabric, generous cleavage exposed at the top. Sweat dotted her forehead and her throat.

“Mmmm, you like that big daddy? You like when I ride your big fat cock?” She purred, switching to short hard downthrusts as she neared her peak.

“You know I do,” he said, matching her movements with hard thrusts of his own.

“Ohhhhhhh, fuck me with your big fat cock, shove that fat cock right up my wet little pussy!” Her words were punctuated with short yelps that grew louder and louder the closer she got, until soon it was just one loud continuous scream of obscenities as she was racked over and over with the crashing wave of an orgasm.

“OhhhhfuckmefuckmefuckmeyesfuckmeyesfuckmeyesFUCKME!”

Paul gasped and he felt his cock explode, building pressure finally bursting in a torrent of pleasure. He watched Kim shake with ecstatic frenzy, her frame shuddering and her lips parted in a wordless moan as she came.

They both lay there, panting and shaking, waiting for each other to come down.

She smiled again. “Mmmm. See, it really is a great outfit, isn’t it?”

It was a few more seconds before he could talk. “Yeah. Very...versatile.”

“Did you notice I kept the shoes on? That’s how you can tell a quality pump, when they’re so comfortable you can fuck your husband’s brains out in a pair.” Returning to the mirror, she straightened her blouse and her hair, wiped the sweat away, and changed her stockings. After a minute’s primping, she was good as new. She gave a little spin, modeling for him.

“Now, I expect that to hold you over until I get back, right? No sneaking off with that little blond minx next door, okay?” Her tone was joking, but her expression was serious..

“Who, Lisa? You're kidding, right?"

"Oh come on Paul, you know she's been sniffing after you from the day we moved in here. It's not like she's subtle about it."

He reached for her hand. "Kim baby, you know you're the only woman for me. Besides, I don't believe for a second that Lisa could have pulled that off in that outfit."

"That's true. She really can't compete, can she?" She leaned in to kiss him. “I have to go, I can’t be late. It’s a long drive.”

“I know. Hon, do you think...” his voice trailed off, afraid to finish.

“What?” she said.

“I was just thinking how nice it would be, you know, if this one last time before you go away for a while, if this would end up being the time, that, you know, finally made it happen.”

She frowned.

“Paul, hon, you know what the fertility clinic said. The odds are really, really long.”

“I know,” he said. They’d had the talk too often for him not to know.

“You have to stop thinking about it. It‘s not your fault. I love you all the same no matter what.”

“I‘m not blaming myself,” he said. “I was just thinking out loud. It could happen you know. They said it’s not impossible.”

“I know. But I don’t want you to get your hopes up. We’ve both been disappointed before.”

“I was just saying, it’s a nice thought.”

“It is.”

They looked into each other’s eyes, neither daring to say what they were both thinking.

“I have to go,” she said finally. “My bags are already in the car. I’ll call you from the road.”

“Alright,” he said. He stood naked in the waning morning light, watching her go, feeling helpless.

“I love you baby. I’ll be back before you know it.”

“Promise?”

“Promise.”

She gave him a quick kiss and was gone out the door. Neither of them knew it would be the last.

***

All the while, the unseen creature had watched them both, ravenously absorbing the stray psychic energy of their lovemaking.

It was a fugitive from another world, the last of its kind, an organism unlike any other in the universe. Its biology demanded that it dwell in and feed off of other living creatures, never truly a separate individual nor ever entirely a part of its host. Its purpose was to spread from world to world and propagate itself and its host species, to the betterment of the planets it visited. Or at least, that was its perspective. The natives of those worlds often did not appreciate its efforts to "improve" their biology...

Hated and feared by the weak and hypocritical inhabitants of the galaxy, these creatures had been hunted down and destroyed wherever they appeared. Now only one remained. It had drifted through aimlessly space, wounded by the attack that had driven it from its last host.

It knew that if it did not find a world with a compatible lifeform soon that it would perish, starving to death in the cold, unforgiving void, its mission to maximize the reproductive potential of other living creatures a failure, and its entire species vanished from the universe.

So it had followed the faintest of biological signals to a planet few knew existed and fewer ever bothered to visit, an out of the way place it could hide. A planet full of quiet, simple creatures who were ignorant of the strange and terrifying inhabitants of other worlds. It came to this world and, in its desperate search to find a host and prevent its imminent death, it came, by chance, to Paul and Kim Greenstreet, on the last occasion that they would ever make love.

The alien’s wounds were so severe that it was barely conscious, and had only a little strength left to move. But even in its weakened state the creature could sense the frenzied psychic signals of ecstatic sex nearby.

Sex was like breath to the creature, and the distinct and tantalizing essence of ongoing copulation awoke it from its torpor, bringing it back from the brink and giving it just enough to feed off of, renewing its ebbing lifeforce. Soon, it started to feel like its old self again

Kim and Paul’s dual orgasms had prolonged its life, but without the shelter of another’s body it would soon expire anyway. A host was needed. It didn’t think it had the strength to head out and explore the rest of this world, so one of these two animals would have to do. But which to choose, the male or the female?

It probed Kim’s mind with one mental tendril. This female creature had a boundless appetite for carnal pleasures, and a variety of unfulfilled sexual fantasies, some realized and some submerged. Very fertile territory that could be explored. And she was parting from her mate, which would provide many opportunities for exploration and experimentation.

But the creature also sensed that the female had no desire to reproduce. She was neither willing nor prepared to conceive children, and secretly she viewed her mate’s infertility as a blessing. The alien could only truly bond with a creature that wished to reproduce, and the notion of an animal not wanting to propagate was completely incomprehensible to it.

The male, on the other hand, ached with the desire to father offspring. The male was also tormented by feelings of guilt and inadequacy over his inability to impregnate his mate. The creature knew that the male’s inherent deficiencies and his obsession with them would make him pliable and easy to manipulate.

Yes, it decided, it would be the male. And through him, this entire planet, and someday the entire universe, would be remade.

It waited until the female had departed. And then it made its move.

***

Paul sat naked on the bed for a long time after Kim had left.

He looked at himself in the mirror, and he saw a man who would never be young again. He might not be old yet, he was still fit and handsome and only thirty three, but he could see his hairline already receding, the lines started to appear on his face, his physique starting to go soft from too much time at the office and not enough time at the gym.

He wasn’t old, but he wasn’t young either, and he was never going to be again. And always at his back he felt the constant, overwhelming terror of it being now. A clock was ticking, and every second brought him closer to-to what? To the point where there would be no turning back, to where the path his life was on would be the path he would be on forever.

He looked at his cock, shriveled and flaccid in the aftermath of sex. A tiny dribble of fluid had leaked onto the sheets. He tried not to think about how the sight made him feel; ineffectual, useless, extraneous.

Do you want to be a father?

Yes, thought Paul, more than anything.

What would you do to make it happen?


Paul blinked. Had someone said something? There was a voice in-there wasn’t a voice in-where was the voice?

What would you do to be a father? What would you give up?


I’d give anything, thought Paul.

And that was all it took.

Paul’s vision blurred and his body seized up. His muscles knotted themselves into a single tight mass and he began to shake and convulse. He felt like there was a fist in the center of his brain and that it was slowly unclenching one finger at a time, and each and every flicker of a finger sent agonizing pain ratcheting through him.

What Paul didn’t know was that the agony he was experiencing was the first part of an incredibly complex process to make his body better suited to accepting the alien as a cohabitant. Human physiology was potentially compatible with its own, but a few...adjustments had to be made first.

Paul thrashed and struggled with his invisible attacker, lashing out uselessly, beating the air with his fists. It was futile of course, since the creature was already inside his body, sending tendrils into his mind, bonding to him.

Paul’s visions failed. His nose bled and foam gushed from his open mouth. A blinding, obliterating headache wiped out his senses except for the sound of his heart beating so fast and so hard that he thought it would burst, and he knew, without really understanding what was happening, that he would die.

And then it all stopped.

Paul lay still on the bed. He opened his eyes. And he was different.

In some ways he was still Paul. He looked the same, had the same memories, the same mannerisms, the same voice. He knew his name, his social security number, and the color of the drapes in the living room. He knew who the President was, what year it was, what time he had to be at work on Monday, and who the surviving members of the Beatles were.

But he knew other things too. He knew about other worlds. He knew about distant parts of the galaxy. He knew about thousands of strange, intelligent, completely inhuman creatures who lived on them. And he knew about an entire spectrum of senses that he had previously been blind to.

Every living thing, no matter how small, was surrounded by a field of psychic energy that he could now perceived, and read, and even sync himself to. It was incredible! By reaching out with his mind just a little he could almost become something else, feel what that being was feeling, and even influence it!

And he also knew that he was no longer in control of his own actions. There was something else inside of him now, in both his body and his mind. In fact, it was now more a part of him than he was. It was the driver and he was the passenger.

This other thing, whatever it was, now knew everything he knew. To some degree, it had taken on qualities of his personality, but its mind was still independent, and he could feel it stirring in him. And he knew its plan too.

All of this understanding took place in less than an instant, the instant in which Paul Greenstreet, as the world and he himself had known him, died, and was instead replaced by something new, something that was partly the alien consciousness and partly the vestigial remains of Paul’s mind.

This new Paul might have liked to have a few minutes to explore the parameters of its being. Unfortunately, that opportunity wasn’t afforded to him. Although it would take practice to fully learn how to operate his new psychic senses, his instinctual awareness of the fields around him told him that something was approaching the house, a human female roughly his age.

His heart skipped a beat. Was it Kim? Had she forgotten something and come back? No, he could hear a knock at the door. He swallowed. What to do? He hadn’t been expecting an encounter like this so soon, it might be smart to wait until he was better adjusted to this new form. Then again, this might be an opportunity that wouldn’t come up again for some time...

“Just a minute,” he called out, loud enough for whoever was at the door to hear. He hurriedly dressed, stopping to clean himself up in the mirror, wiping the remains of his nosebleed up with an old shirt from the hamper.

Opening the door, he was surprised to find a shapely, curvaceous thirty year old blond smiling at him on the doorstep. Her luxurious curling hair spilled over her shoulders and she was dressed in a hot pink tank top that displayed generous cleavage while hugging and accentuating the sides of spectacular breasts, along with white khakis painted onto the curves of her shapely hips, ass, and legs.

“Hi Paul!” the woman said, startling him by breezing right past him and into the house.

He groped for a name for a second. “Lisa! Hey, good to see you. What can do I do for you?”

“I just stopped by because it looks like I got some of your mail again. Nothing important, mostly junk, but I thought you’d want it. Is Kim home? The lingerie catalog is for her. At least, I hope it's for her!" she laughed, too loudly.

“You just missed her. She’s out of town on business," Paul said, closing the door.

“Oh? Not for long I hope?”

“Two weeks. Big conference, and then she’s contracting out to another company to help them get streamlined for a merger. Whatever that means,” and he laughed too, too loudly.

“Two weeks, wow, I had no idea.” She was lying, the alien could tell. Her psyche projected loud and clear that she had known Kim was leaving town, had actually watched and waited for her to go, and made a point of showing up now, the first opportunity after she was away.

“Yeah, it is. Look Lisa, I-"

But she didn't listen, instead walking right past him and into the kitchen. "Do you mind if I get a glass of water? It's hot out there today."

She helped herself without waiting for an answer, and Paul watched as she drank and a single drop slid down the side of the glass and landed on her exposed cleavage, trailing a curve. He wondered if she had done it on purpose?

Meanwhile, the alien entity experimentally studied Lisa's mind. She was clearly interested in mating, in fact it was the sole subject of her thoughts. It probed Paul’s memories and discovered that its host had long been attracted to this female, but had passed up numerous opportunities to mate with her. Why?

Lisa caught her breath and smiled. “Thanks, I needed that. I think I pushed myself a little too hard today.” She glanced out the kitchen window. “You have such a beautiful backyard. Do you keep it up or does Kim?”

“She does.”

“I can’t imagine how she has the time. Ah, look, there’s my bedroom window right over the fence. Did you know there’s less than ten feet between your bedroom window and mine?”

Paul forced a smile. “Guess it’s a good thing we keep the shades drawn then.”

"Yeah, although, you know Paul," she gave him a sly look, leaning her back against the kitchen counter, adjusting her posture so that her breasts were pushed firmly forward and her legs slightly parted. "I don't want to embarrass you or anything, but you should know that sound carries pretty well between our two houses. I can hear you lots of times. I could hear you this morning."

"You mean-"

Lisa grinned, then dropped her voice down into an imitation of Kim's throaty purr. “’Fuck me with your fat cock, big daddy.’” She looked at him coyly, waiting to see how he responded.

Paul made sure to look surprised at first, and then slowly let a mischievous smile play over his face.

“You heard that, huh?”

“Yeah, I did. Quite a mouth on that woman of yours Paul.” She stepped closer to him, putting one hand on his arm. “You like a woman with a dirty mouth, don’t you?”

“I guess I do.”

“I can tell. Did you know I’ve got a dirty mouth, Paul?”

“Do you?”

“Uh huh. Would you like to see what I can do with it?”

“Lisa, I-”

“Shhh. It’s okay. Kim will never know. It'll be our little secret. Besides, what do you think she’s going to be doing for two weeks on her own, wearing out her vibrator batteries?" She leaned up to whisper in his ear, licking his earlobe while she did. “I know you want this as bad as I do Paul. You’ve had your pants unzipped the entire time we’ve been talking.”

He looked down. She was right! He hadn’t even noticed, but she thought he did it on purpose. No wonder she had been so worked up the whole time!

Lisa’s hand slide inside his open fly, probing until her fingers glanced over his erection and then squeezing experimentally. “How about it, ‘big daddy’? You want to see what my dirty mouth can do?”

Before he could answer she was on her knees, tugging his pants down and pulling his rigid cock out. At the back of his mind, the alien entity watched, passive for the time being. This would be its first experience in the new host. It would be most...educational.

Lisa held him in her hand, fingers wrapped firmly around the base, giving a couple of half strokes, testing it and finding it eager and ready. Without breaking eye contact she extended her long pink tongue and flicked the tip. Paul shivered, and the alien consciousness eagerly devoured his reaction.

“I know Kim won’t do this for you. I’ve heard you ask. I told you the sound carries.” She squeezed a little tighter, tickling the underside with her tongue, licking up and down, wetting his shaft before circling around the head. Paul gasped and moaned, running his fingers through her crisp curling hair, gripping a handful.

“You should have asked me, I would have done it a long time ago. I’ve been hungry for it, all this time.” She opened her soft pink lips and began to suck tenderly at the swollen mushroom tip, moaning in her throat, the vibration sending ripples up Paul’s member.

“Mmmm, it’s even tastier than I always imagined." She giggled, tickling his balls with her tongue. The alien watched as Lisa sucked wetly on Paul's cock. The act she was performing had no discernible reproductive purpose, but it clearly was stimulating both the male and female animal. Curious, the creature reached out with its mind, syncing with Lisa's psyche and observing her thoughts in greater detail as she indulged herself.

Lisa swallowed the swollen head between her soft, inviting lips. Cradling his balls in one hand, she began to work the tip, tasting, letting him enjoy the luxurious feel of her hot wet mouth slowly enveloping him.

She opened wider and began to swallow him one inch at a time, moaning with pleasure so that the vibration of her lips stimulated his shaft. She sucked her way down to the base, deepthroating him, savoring the feel of a thick bulge stretching out her lips and pushing all the way to the back of her mouth and beyond.

To think she was finally sucking Paul’s cock! That stuck-up bitch Kim didn’t know what she was missing. A man like this needs special attention.

Ever since they had moved in two years ago Lisa had had her eye on Paul. Not just because he was handsome and polite, but because it seemed his wife never really respected or appreciated him. Lisa knew what that was like, she had been in a one-sided marriage once too. She wanted to show Paul that a real woman appreciated a man like him, and knew how to take care of him.

She bobbed her head up and down, her mouth watering as her hot sucking lips drew him in and let him glide across the inviting pad of her tongue. She had dreamed about this for so long and now that it was finally happening a frantic, ravenous hunger had awakened inside her. She filled her throat, pursing her wet lips and making obscene little sucking noises as she gorged herself.

Lisa quickly stripped off her top. She had made a point of wearing no bra, and now her ample, generous 36DD breasts were exposed for Paul's viewing pleasure. She winked as she cupped them, still deepthroating him hands-free, rubbing around and around her red swollen nipples with her thumbs and squeezing with her fingers, jiggling them for him. Even Kim didn't have a rack as nice as this, Lisa knew. She would show Paul everything she could do for him that that bossy ice queen couldn't.

The entity returned to Paul's mind, intrigued and enlightened by its brief sojourn into Lisa's thoughts. It watched as she pulled his cock free of her mouth with an audible "POP" and then lay on her back on the floor, tugging her too-tight khakis down and exposing herself to him, legs parted, fingers poised just above the tantalizingly inviting entrance to her sex, fingers glancing against her own swollen, engorged clit.

"Fuck me Paul," she growled. "Fuck me right here, right now."

Paul began shedding his clothes as well. "You want it right here?"

"Fuck me right here on the kitchen floor. Fuck me right here where you eat breakfast with your wife every morning. Take that nice big tasty dick of yours all wet from my mouth and shove it up my hot little pussy. Just give it to me baby, I want it. All of it."

Paul paused, looking down at her. "You really want it all?"

She purred incorrigibly. “Oh yes.”

“Are you...sure?”

“I’m more than sure baby. Give it to me. I need it.”

Paul hesitated only a second longer. Then he shrugged. “Alright Lisa. If you really want it all...”

And then he changed.

When the alien bonded to Paul, it redesigned his entire anatomical structure. Outwardly, he appeared as he always did, but something else was living inside of him, and now he let it out. His whole body shifted and slid into new configurations, his features melted away and his form merged into itself. In a few seconds, what stood over Lisa’s naked body was something entirely inhuman.

Her mouth gaped and shock paralyzed her. The thing in front of was primarily a shapeless, blob-like mass that floated two feet off of the floor, supported by gently waving masses of thin, sucker-covered tentacles. Its flesh was translucent with a faintly purple and blue tint, and the memory, unbidden and divorced from context, of the jellyfish she had used to love watching at the aquarium her father took her to as a child flitted to her mind. The entire thing throbbed with excitement as the sexual energy permeating the room after her shameless tryst with Paul fed and strengthened it. Three dull orange eyes swiveled in their sockets on the creature's body, fixed dead on her.

The change came so fast that Lisa didn’t even have time to react before the thing was on her. Almost immediately a dozen slimy tentacles whipped forward and ensnared her, wrapping themselves around her waist, her shoulders, her arms, her neck.

Four more attached to her ankles and pulled, spreading her legs, and a half dozen twined around her generous breasts, squeezing and constricting them, the transparent ooze covering the monster’s body smearing across her naked flesh, punctuating her erect nipples so that they gleamed in the light. By the time she even thought to scream, it had her completely trapped and at its mercy.

The creature took a moment to enjoy the freedom of reverting to this body for the first time. Maintaining the appearance of normality to the native creatures was important, but here, in private, and in the midst of an intimate moment, it preferred to really be itself.

And what a delectable female it had found for its first experience on this world! The woman was now screaming and struggling quite ineffectually. It reached out with its swirling mass of appendages and gently caressed her naked body, trying to soothe her. Probing tentacles played along the outline of her figure, tracing the path of her hips and thighs, smearing wetness on her warm, soft flesh. The alien quivered in anticipation of what was to come next.

Even as Lisa tried with all her might to escape, the creature’s many prehensile limbs were busy subjecting her sensitive breasts to sweet, agonizing torments. It mimicked her own movements of a few moments ago, twisting and pinching her nipples until they reddened and swelled with excitement. Separate tentacles twined themselves around each breast and squeezed, massaging them. It was precisely the sort of foreplay Lisa loved most, and even as she panicked and screamed her body was responding to the physical stimulation. Against her will, wetness blossomed between her legs.

The alien knew an invitation when it saw one. Three particularly large tentacles, each almost the thickness of a human arm, sprawled from its center body mass, snaking their way across the linoleum floor to where Lisa’s naked, helpless, wriggling form was trapped in its coils.

Lisa moaned and whimpered in desperation. She knew what would happen next and she knew she couldn't stop it, but she tried anyway.

“No! No, please, don’t, don’t, don’t-ahhhhhhhh!”

Her back arched and her body rocked as one thick, swollen tentacle plunged into her wet pussy. The muscles of her sex tightened reflexively around the intrusion even as she begged for a reprieve. The strange member was covered in protruding ridges that stimulated her swollen lower lips and pressed against her throbbing clit as it entered her. She had asked for it,. and now Lisa really was getting it all.

The alien was pleased. The physical sensation wasn’t like anything it had ever experienced before! Though it had inhabited countless species on innumerable worlds it never partook of a creature for which mating involved such delicious and uninhibited physicality!

It pumped the probing tentacle experimentally inside Lisa, testing the strength of her internal muscles and the pliability of her wet lips. It massaged her naked skin with its forest of other limbs, relishing each and every bare inch as it passed under its touch. Extraordinary!

Lisa felt like she was going to pass out. The combination of fear, shock, disgust, and bewilderment, mixed with the horrifying eagerness of her body as it responded to the creature’s touch, was too much for her. She closed her eyes and clenched her jaw, low animal grunts slipping from between her teeth even as she tried stifle the noise.

The creature’s enormous probing tendril was now buried deep inside of her and fucking her with a force she had rarely experienced in her life. The heavy pounding of each thrust pushed deeper inside, and a throb of appalling pleasure twisted and contracted in the center of her being. She wanted it to stop. She wanted to stop liking it. But she couldn’t!

The alien was so busy fucking her with one of its specialized tentacles that it nearly forgot about the other two. Realizing that, amazingly, the situation had not yet reached its full potential, it pushed one more limb forward, the tip hovering just in front of Lisa’s face. Sweat, both from terror and exertion, shone on her forehead, and as her body shook it was equal parts fear and orgiastic satisfaction that caused it.

The creature produced a noise very much like a voice, and the words it spoke were perfectly understandable despite the inhuman anatomy producing them:

“Let’s see what you can do with that dirty little mouth of yours.”

All of Lisa’s protestations weren’t enough to stop the tentacle from forcing its way past her lips, into her mouth, and down her throat, pushing until she gagged. The thick, slimy liquid that covered the monster's body collected on her lips and she involuntarily swallowed mouthfuls of it as it began to mercilessly fuck her mouth in the same rhythm it was working on her lower orifice.

She couldn’t scream with her mouth crammed full like this, but she tried. The tentacle was shoved so far down that it very nearly filled her entire esophagus, threatening to choke her to death. The lower tentacle ground and twisted inside her body even as the upper pressed deeper and deeper. Both tentacles were in so deep that she had an image of them meeting in the middle of her.

Now that she was not only restrained but twice impaled on its probing tendrils, the creature picked Lisa up off the floor and began to fondle the rest of her naked body. The accosting tentacles began to massage her bare skin, and she jerked as she felt its touch on the smooth, rounded flanks of her pert little ass.

Reaching back into Paul’s memories, the alien remembered that Kim had always responded well to stimulation of this orifice. Would this other female respond the same way? It was pleased to find that she did. The tight, puckered rim of her asshole opened almost eagerly for the last of the thick, ridged tentacles, and finally Lisa was truly and completely being fucked every way possible.

All rational thought was now crowded out and distorted by the throbbing aching pulse of her body as the horrendous thing penetrated her three ways, fiercely and mercilessly fucking all her holes with a constant, steady stream of pumping thrusts. She couldn’t think, couldn’t move, could barely breathe, all she could do was feel, and what she felt, against her every wish and inclination, was raw physical gratification of the most potent variety she had ever experienced.

She didn’t want to resist anymore. She wanted to give in, to let go. What was happening to her was so strange, so confusing, so terrifying, that her mind couldn’t cope with it. So instead it simply turned away, and, left with only physical sensation divorced of all conscious reason, she submitted to the rising and relentless impulse to indulge.

Soon she was no longer screaming, she was moaning. She wasn’t struggling., she was writhing. Her lips wrapped themselves around the intruding member and she sucked it eagerly, swallowing, an obscene slurping noise issuing from her mouth as she deepthroated the monster.

Her hips bucked with each thrust into her hot, surging cunt, wetness dribbling down her naked thighs, and her ass cheeks jiggled as it slid into her tightest and most inviting of holes. Soon she was orgasming, over and over again, in blinding, obliterating waves of pleasure that blocked out everything else.

Ah, thought the alien, the moment it had been waiting for had finally arrived. Though it had redesigned its hosts anatomy, it still retained a elements of the original creature’s body. Since it had observed that animals on this planet fertilize females by releasing fluids at the moment of greatest sexual gratification, it followed suit.

One by one the penetrating tentacles began to pump thick, gelatinous cum into Lisa's open orifices. She writhed in uncontrollable ecstasy as it spurted, filling her pussy and her tightly puckered little asshole. Her tongue lapped at the one shoved down her mouth, feeling the alien appendage swell and pulse with the raw force of orgasm. Cum spilled over her tongue and, filling her mouth, dribbled over her lips and chin even as she gulped it in greedy mouthfuls, tasting it hot and sweet as it ran like a faucet down her throat.

Now the creature really got down to business. It understood that a female of this species usually could only carry one fertilized egg at a time, and the chances of pregnancy after mating were shockingly small. But it had other plans for Lisa. As the alien fluids reached her uterus, her ovaries went into overdrive, discharging every single one of their eggs, dumping them into the womb which was by now filled to the brim with extraterrestrial cum. The eggs fertilized instantly and attached themselves to her uterine walls, and her abdomen began to expand.

Lisa looked down, amazed, as her belly swelled and inflated. Something squirmed inside of her. She might have felt frightened if she hadn’t been lost in the throws of mind-obliterating orgasms, one on top of another. She threw her head back, eagerly sucking another load down her throat, gasping and moaning as she feels the inseminating tentacles fill her up in every way possible. She had been empty and now she wanted to be full, so full she overflowed.

The monster continued flooding her body with its juices, far more than was necessary for fertilization. The compound it produced wasn't just there to communicate its DNA, it was also a nutrient solution which would not only sustain the incubator through her entire gestation process, it would feed the young when they hatched as well. They would remain inside for some time after they were born and would not yet have powerful enough psyches to feed off of mental energy, so the slurry rapidly filling Lisa's body would take care of them until they were ready to come out into the world.

The tentacle planted in Lisa's pussy pumped her full until her distended uterus was so swollen that her belly expanded almost to the size of a beach ball. Looking for space elsewhere, it poured fluids into her ass and mouth, letting them seep into her body cavity. Two tiny suckered tentacles attached themselves to her nipples and began ejaculating into them as well, liquid diffusing through the skin, causing her breasts to inflate until they were enormous, sloshing, nutrient-filled sacs attached to the rest of her body.

So saturated was she by this time with the alien's cum that her skin turned almost translucent and was moist to the touch. Her figure was now dominated by her bloated abdomen, and just above it her gigantic, fluid-filled breasts. When the inseminating tentacles finally retreated and she had time to concentrate on something other than pleasure and her greedy suckling of mouthful after mouthful of the intoxicating slime, she was shocked by what she saw when she looked at herself.

She reached up, putting her hands to the side of her enormous belly. “What, what is this-?” she mumbled incoherently, her lips still thick with cum. Her head was spinning, and thoughts came in a daze, hazy and incomplete.

Rejoice! You have reached the next stage of your existence. Now you are an incubator, a vessel for new life.

“I’m pregnant?! No, I can’t, I mean, my babies, they always die, that‘s why my husband left me, he said if I couldn‘t, if we couldn‘t, if we-” she was trying to cry but no tears would come. She didn’t know it was because the alien had altered her body so that all “wasted” fluids were redirected to the nutrient reservoir instead.

That’s behind you now. These will live. You are female, and this is your purpose. Be thankful, for it is now fulfilled.

“But, but-” Lisa experimentally pressed on the sides of her incredible, inhumanly engorged body. She could feel them inside. How many? Too many to count. And they were a part of her, her children, and she would protect them and feed them until they were grown and went out into the world. How wonderful, she thought, to really be a mother at last!

And, while she was distracted by the overwhelming maternal instinct that the alien had instilled in her, it reached into her mind and simply switched her off. So traumatized was she by the experience she just had that it took only a small effort to push her into a dreamlike state, deep and dark and comforting. Meanwhile, it stimulated her pleasure receptors and then set them to run at a full, automatically. She would spend the rest of her life in a deep, rapture-filled dream while she carried her children to term. There was no more pleasant fate, from the alien’s perspective anyway.

The mass of tentacles crept back and retreated, vanishing into their host, and Paul, or whatever was left of him, became himself again. He looked at his body, naked and covered in a thin layer of transparent ooze. Then he looked down at the figure lying on the linoleum. Is that really Lisa?

He put his hand to her belly. There was movement inside. Oh my God, he realized, I’m a father! A father of many, many, many special children. He knew that these gestating young would carry traces of his DNA, and of Lisa's, but that they would be of the alien visitor's species. It allowed its host and mate to fulfill their biological obligation and pass along their genetic material even as it advanced its own agenda. A most equitable arrangement, as far as it was concerned.

Paul squeezed one of Lisa’s swollen, engorged breasts experimentally. It gurgled under the pressure and he could hear fluid sloshing inside. It felt spongy and moist, the nipple flat and distended. One thing was for sure, when his new children were finally born they would eat well. Lisa’s mature but deliciously potent body would make the perfect incubator. He was a good provider.

Paul toweled himself off with a dishrag off and then dressed. He threw Lisa's clothes in the trash, then hefted her body and took her out of the kitchen and into the hall. He took the basement steps one at a time, so as not to lose his balance with the heavy load he was carrying. As he set her down in one corner, a moan of pleasure slipped out of her mouth. Well, at least she was still having a good time.

He stood in the center of the basement and closed his eyes, letting his mind expand again, feeling the biological echoes all around him. Lisa was a good start, but to truly remake this world he would need more. Millions and millions of offspring to cover the face of the planet, transforming every male into a creature like him and they, in turn, transforming every female, pushing the human race forward to realize their full reproductive potential.

But there was a lot of work to do first. He could sense many females in the radius of his mind. A few were too old to have any reproductive potential left, and many others were too young to be put to such ends. And of those remaining, only those with a powerful desire to breed could hope to survive the trauma of mating with the alien lifeform.

Even so, he sensed mature, fertile, desirous women everywhere. There was so very much out there for him, and he had so much to do.

But something was wrong.

Fertilizing a female was one thing, actually triggering a birth was another. The alien’s race was trisexual, requiring a third party to catalyze the birthing process. Without this third element, the young would never leave the womb. Once they had consumed the nutrients immediately available to them, they would simply starve without ever emerging. The alien would have to find a female to transform into this third creature, to fill that role when the time came. And to fill that role, not just any female would do.

It would have to be someone unique. Someone special. Someone with a quality that the creature itself did not fully understand. And none of the females it sensed possessed it. None, except...

Paul opened his eyes and walked back up the basement steps, turning the lights out on Lisa as he went.

He picked up the phone. His fingers dialed the numbers from memory. He wasn’t looking at the phone, he was looking at the calendar.

“Hi honey. I missed you already. How long are you going to be gone again? Yeah, I forgot, I’m such a goof. Two weeks, really? Well damn. I hope you can get back early. I have a surprise for you. A special surprise. No, I can’t tell you, that would ruin it. Trust me though, you’ll love it. It’s out of this world.”

To be continued!
