This asteroid was different, not for what it was but for what it contained. Within the pod slept a creature. It traveled in the black void between stars; it was drifting, dormant, sleeping away the millennia in a state of hibernation. Even in hibernation, all that remained was a seed, a shadow of former life waiting to be born again. It had been drifting so long that it didn't remember where it had originated. The long eons had drained its intelligent sentience to its current state, not conscious but simply existing as everything but its unending hunger faded away.

Through the endless years, the being endured it all until finally, something began to change. The distant touch of light and radiation of deep space began to give way as the heat of a nearby sun warmed it ever so slightly.

Countless eons after it had been sent out into space, long enough that it might be the only survivor of its species of all the thousands sent into space, it began to awaken. It had no communication with any of the others, nor had any idea where the others were. Were they close or light-years away? The slight brush of gravity played across the surface of its vessel. Opening its senses, it discovered a living, vibrant world, a blue and green jewel of a planet, a planet that had captured its pod in orbit. With an innate thought, the creature sent the pod falling toward the globe below, summoning the last of its vessel's energy in a final effort to reach a living world. The remaining energy was enough – barely, and the long fall downward began.

As the pitted shell of its vessel began to glow with the heat of atmospheric re-entry, the creature sensed a ready supply of sentient life energy below. For the first time in its long memory, it could feed. It fell through the atmosphere, friction heating its outer surface until it became a blazing spear plummeting downward. In fire, it was reborn. Rock burned away and stripped of its concealment, the true nature of the seed was revealed. A mixture of organic and metallic components merged, making it nearly impossible to determine where one ended and the other began. That, however, was merely a shell intended to protect the true cargo within.

It didn't feel the crash of its vessel. It didn't know it had crashed through glass into a building. It only knew the basics. There was food here, and it could at long last feed.

"Two affairs, a loveless marriage, it's a pity a man had to die because all the people involved were too scared to say what they really felt. Hiding behind lies," Roy told her after they'd solved case

"Yes, it is sad," Kate agreed and watched Roy walk away, while a happy and smiling Castle was on his cell phone, talking to someone.

"Hey, I gotta run. I have to drive Alexis to Princeton. I'll see you tomorrow." But Kate had a different look on her face. One he couldn't place. "What?"

"Nothing." Kate shook her head. At that moment she knew she was in love with him. Things were different between them. She was living a lie because she was too scared to tell him, exactly like her victim. People were too scared, too intimidated to talk. To say what they felt.

However, the very next person she saw was Demming. She did like him, but she wasn't falling in love with him. He was a nice guy, but he wasn't Castle. If this was going to work, she needed to dump him, and he wasn't going to like that.

She was using him. Playing him along because Castle scared her, though what Roy had just told her had managed to reach her. Somehow that one statement had breached all her walls.

She had a week's vacation coming up, and yes, she'd been caught in a lie. She had said no to Castle but had said yes to Demming. So she had an entire week to go to the Hamptons with him. What she needed was to dump Demming. Then she'd go home, pack a bag, and show up at the loft, asking him if his offer was still open.

What happened once she was there had yet to be seen. But she wanted to be ready. She felt like she was ready for it to be them, not her or Castle, but them. Both of them.

o[)(] o

Demming had actually taken it pretty well. He didn't understand why because he thought they had something. He didn't understand what it was that she was looking for. He felt like he was the right person. She was definitely the right woman.

Kate went home so she could pack. She was even thinking of just what she was going to pack. She had some seriously sexy, lacy lingerie that she hadn't worn for anyone else to see. She even had a bustier that presented her breasts to whoever was looking. She was grinning just thinking about it as she entered her apartment, locked the door behind her, and turned and saw…

"OH, SHIT!" That sure as hell wasn't what she needed right now. One of her windows was damaged. And there was something that still looked kind of hot that was sitting in the middle of her living room.

Kneeling to look at the thing, she held out a hand over it to feel its heat. It wasn't hot enough to start a fire, but hot enough. It meant she wasn't going to touch it, that was for damn sure.

Standing up, she took out her cell phone and called the building's super. It looked like a rock about the size of a baseball, but far more rough-looking, pitted and scarred from re-entry. She needed this thing gone, and her window replaced or at least sealed and replaced later.

"Voicemail!" Great, that was just great. She didn't need this. Worse, what if the repair delayed her, and Castle left for the Hamptons without her? She had worked up the courage to go to the loft and tell him. Now she needed new courage to ask him not to leave without her.

Maybe they could leave in the morning? It depended on how long it took the super to listen to his voice mail, or voice mails, plural. She needed this fixed today since she planned to go to the Hamptons with Castle. Why did her life have to be so damn complicated?

Still, she needed to pack, so she left the hot rock and the broken window and headed to her bedroom. She found her bag and began choosing things to pack. She needed more than just sexy underwear, but she needed to keep his eyes locked on her and not someone else. She had already noticed that he had eyes for women with big boobs. Even if they were obviously fake.

The last woman like that had more silicone on her chest than she did skin, or fat, or muscle. Or anything else, for that matter. Kate didn't, and she was envious of women that had honest-to-goodness boobs that were that size.

Her time as a 15-year-old teenager had her praying she would finally fill out and give her the size boobs she wanted. She had eventually filled out, but not to the cup size she had dreamed of. Still, she did know what her best attribute was, and she didn't mean her mind – she meant her long legs.

o[)(] o

Finally, with her bag in hand she came back into her living room and found the hot rock hadn't miraculously vanished. Nor had the broken window been magically repaired. So she called the super again. Whatever it was, it had to be taken care of before she left. She couldn't leave some kind of hot rock in the middle of her floor, along with a broken window.

"Voicemail. Damn it!" Now she needed to stop Castle from leaving too soon. This whole situation was so not fair.

o[)(] o

Castle almost hadn't believed her when she'd asked if she could come to the Hamptons with him. He had literally stopped talking. For Castle, that was damn near impossible. But he would wait for her to call him after she solved her problem that she wouldn't talk about. It was just that she had to do something first.

So there she was, sitting on her sofa, waiting for the super to call her back and to come up here and fix this. She hadn't meant to fall asleep on her couch, she truly hadn't. Maybe it was the case or her exasperation over having to wait for the super to fix this. It was just life in general, but she'd about had enough.

With a wet crunch, the chitinous outer shell cracked open with a hiss of equalizing pressure and a puff of cloudy gases. Within the pod, the alien quivered with delight. A host was near! It had been so very long without a host, drifting alone in the cold void, kept carefully at the edge of death by the organic systems of the pod. But now the wait was over. The pod had descended to a habitable environment and detected a suitable host nearby.

Several whisker-thin stalks emerged from the pod and waved gently in the air as the alien tasted its new environment for the first time. The atmosphere was rich in oxygen and bore the telltale traces of early technical civilization. The stalks turned to focus on the warm object lying near the pod. The alien was filled with gleeful anticipation at the thought of bonding with this host. Slowly, manipulative tendrils thin as spaghetti reached out from the pod and wriggled along the floor toward its future host.

At the first touch, it quivered and shook as the sensory organs which covered. Within it, thousands of biochemical processes began, analyzing the host's DNA and initiating the changes which would allow it to conform to her body's chemistry so that the process of taking her as host would not kill her. Despite its current non-sentience, its being vibrated with delight as information continued to flow in from its sensory organs. These beings would make excellent hosts. They lacked any meaningful defenses against a biological takeover and possessed a sturdy physical structure that would be easy to modify. The alien gathered its worm-like body and flowed partway out of the protective pod that had housed it for so long. Thicker grasping tentacles moved slowly to grasp the host's body, lifting her into the air and drawing her carefully to the pod. It needed to protect the creature, its valuable host's form, while it set about taking her.

When Kate finally regained consciousness, it was already inside her mind. It was subsuming her and taking what it wanted, picking through her thoughts and memories, probing at the very core of her being, and cutting her mind apart with a touch which was both delicate and irresistible. Already so much of Kate was gone, drawn into the incredibly alien presence. There was just enough of her left to be surprised at just how good it felt as her mind was consumed by her new owner before oblivion swept her away.

Kate rose to her feet and stretched before taking a few cautious steps as she grew familiar with her new body. Looking down at her new body, nubile and glistening, she realized that she would would need different clothing, perhaps, as she changed this body. Sparing one last glance back at the pod which had so changed her, Kate began working her way to search her immediate area.

Already genetic memories were making themselves known to her new mind: ancient knowledge of how to hunt, how to seduce, how to survive, how to reproduce. Most important of all was the final piece of knowledge which made itself known as she realized the insatiable hunger which filled the core of her new being.

HOW TO FEED.

o[)(] o

Landing + 10 hours

A knocking noise had Kate headed for the sound. It looked to be a simple barrier. Even better was that she could sense a male was on the other side of the door. It was time to feed. She just had to let it enter.

Getting the barrier to open had proved to be easy. It allowed her to gaze upon the male on the other side. He was older than she liked, but he was a male, and she had a hunger.

As she drew close to the stunned man, the internal changes came into play. Her body began to produce pheromones of a far greater potency and concentration than an ordinary human's, capable of creating an overwhelming level of sexual arousal in her victims. At the same time, her puffy labia swelled outward, revealing the wet pink flesh inside as her vagina began producing copious amounts of lubricant, causing the material she wore to become soaked.

She smiled as she waited; it was obvious that her pheromones were beginning to affect him when his skin became flushed and his breathing began to quicken. He was also having a great deal of difficulty maintaining eye contact with her, his eyes kept straying downward to her pert breasts and then further down to her swollen Mons. Against his will he was rapidly becoming aroused by her presence.

In her green eyes, specks of gold glimmered and danced. He felt something like a moment of vertigo before his jaw slackened, allowing her tongue to explore his mouth in a kiss. As he continued to stare into her hypnotic gaze, a burning desire began to throb in his body and mind. Rational thought faded while his cock became rock-hard in his pants.

Kate's eyes gleamed with delight as she sensed his resistance break, replaced by need instead. She guided his hand between her legs, allowing him to feel her excitement while her own hands went to work rubbing and caressing the man's hardness through his trousers. They moaned into each other's mouths as their tongues sparred. Nimble female hands unfastened his belt and quickly undid his pants, freeing his erection before pumping and caressing it as they smeared pre-cum along his length.

Kate forced the man to the floor, taking him by surprise. Both partners moaned in pleasure while Kate worked herself against his cock. Finally, Kate drew back, angled her hips, and ripped away the material between his penis and her entrance. The head of his penis nudged into her entrance and Kate grimaced in pleasure as she slowly pushed downward, little by little impaling her tight vagina on his stiff cock until she buried to the root.

She smiled and closed her eyes, laying her head against his chest as she grew accustomed to the feeling of penetration, experimentally clenching her inner muscles to squeeze the member which filled her cunt. Slowly she began moving, rising up and down as she felt his shaft rub against her inner flesh. Moving faster and faster, Kate was soon crying and panting as she pounded herself down on him.

Kate squeezed and rippled her inner muscles, milking his cock while she let out little shrieks of ecstasy and bit her lower lip with pleasure. Her response to his thrusts only aroused the man more, and she moaned in anticipation as she felt him double his efforts, hammering into her body as he strove toward his peak. Like an animal, he impaled her again and again, stroking hard and fast as he fucked her. With a hoarse cry, he finally came with an orgasm unlike he had ever experienced before.

An expression of confusion appeared on the man's face as his body continued to thrust into Kate outside of his conscious control. He couldn't stop coming inside her clenching depths as his climax went on and on without release. A tortured cry of intermingled pain and pleasure was wrenched from his throat as his cock jumped and pulsed, spurting his seed deep into her womb.

She laughed evilly, feeling his life-force flow into her body, strengthening her and bringing with it a buzzing ecstasy which coursed through her core with an intensity far greater than mere sex. The succubus watched with a wicked smile as the life drained from his eyes.

Kate smiled victoriously. She slowly ground herself against his still erect cock with a hand pressed against her flat belly, reveling in the afterglow and the satisfaction of feeding upon his life's energy. Finally, with a sigh of regret, she rose to her feet. As she did so, her victim's cock slid from her vagina with a wet sucking noise.

Looking down at the male, it was obvious that his body was worse for the wear. His skin had turned grey, and he seemed slightly shrunken. Every vein in the man's body was now black.

Kate's mind told her of another male she could feed on, and he was expecting her. So she put on a skirt she found but skipped wearing panties since they just got in the way. So did this thing that was on her chest, enclosing her breasts that were now bigger. The life-force she had drained from the man allowed her to make changes to this body. Instead of 35B breasts, she now had breasts that were easily size 35C. She kept the long legs, left this space, and used what she'd learned from her host to go to him.

Except what was on the other side of the door wasn't a male but a female. That, though, was a bonus. She could put her to use as well.

"Detective Beckett! Dad's not here. He said he had to go out and get something. He was supposed to be going to the Hamptons, but he said he had to get something first," Alexis explained.

As Alexis talked to Kate, a strange scent of musky sweetness was filling the air. Unconsciously, the teen began breathing deeply, filling her lungs with the pheromone-tainted air of the room. Falling into a daze her eyes became glassy, and she began to pant as her body responded to the pheromones.

Her vagina began to moisten and a burning need began to grow in her groin.

She became hyperaware of Kate's warm body and the press of her firm breasts as every inch of her skin began to tingle.

"What…what's happening?" Confusion and disgust began to fill her mind; how could she feel this way about a woman, let alone Kate? Her cheeks began to burn red with shame as Alexis tried to deal with these immoral and unexpected feelings while she involuntarily rubbed her thighs together. Kate leaned forward and kissed her.

Alexis's eyes widened in shock when Kate's tongue separated her lips and forced itself into her mouth. That shook her from her trance, and Alexis stiffened. She tried to push Kate away only to find that her arms had locked around her with the strength of steel bars. She fought helplessly against Kate's irresistible grip and copious amounts of sweet saliva flowed from her mouth into her own. Reflexively, she swallowed the sweet sticky fluid. Suddenly she found herself relaxing while a calming warmth came from within her belly, and a tingling sensation began to spread throughout her body.

Kate drew back from the kiss, leaving their mouths connected by a thread of sticky saliva, and looked directly into her blue eyes. There she found the glassy-eyed arousal she was looking for, bringing an evil smile to her face. Catching her stare, Kate's eyes bored in with a sudden intensity, riveting the aroused girl's attention with a gaze the girl couldn't avoid. Distantly, Alexis noted that golden sparkles seemed to dance and play in Kate's green eyes. She felt like she was falling into them; they were so very deep that she could drown in their unwavering look. As this almost subliminal sparkle continued to pulse and swirl, she felt herself slowly relax, surrendering to the dreamy feeling her eyes instilled in her.

Once Alexis had relaxed in her embrace, Kate picked her up and slung her over one shoulder in a fireman's carry. That roused Alexis slightly from her trance and she mewled weakly in protest while being carried up the stairs to her bedroom. When the succubus tossed her onto her bed Alexis let out a squeak of surprise.

"Take off your clothes." Kate was quickly and efficiently removing her own clothes. After her perfect body was exposed, the succubus noticed that Alexis was sitting on the bed, frozen as her expression alternated between guilt and hunger.

"I said take off your clothes." Kate stared deeply into her eyes, riveting her with an unwavering gaze until a captivated Alexis could only obey, succumbing to her growing arousal and the strange influence Kate seemed to possess. Alexis quickly stripped, exposing her fit, young body.

Climbing onto the bed, Kate swiftly displayed her dominance. She pushed her onto her back and climbed on top, straddling the hapless teen. Kate placed Alexis's hands on her breasts and used them to massage the firm orbs. When Kate dropped her hands, Alexis continued to squeeze and caress the shapely mounds. That left Kate's hands free to explore every inch of her body, stroking and caressing as she drove the teen's arousal to new heights until she was almost sobbing with need. Alexis dropped her right hand from Kate's breast and began frantically touching and stroking herself in a futile attempt to lessen the burning need she felt.

Alexis cried out in disappointment when Kate climbed off of her. Kate ignored her complaints and moved so that she sat facing her. After placing her right leg over Alexis's left and vice versa, the succubus scooted forward until their vaginas kissed, and Kate began rocking back and forth, grinding her wet slit against her. Kate's tainted juices only aroused Alexis more, and she could only whimper pitifully in pleasure as one shuddering orgasm after another ran through her body until she lay exhausted but still twitching in pleasure. They strained together for nearly fifteen minutes before Kate decided it was time.

Kate gritted her teeth and pushed, smiling as a conversion module slid from her between her lower lips and nudged its way into Alexis's waiting slit. The module was black, about four inches long, and one inch wide. It was tipped with short, writhing, motile tendrils to draw itself into a host and had a segmented body which narrowed at the end. Right now, it took advantage of its segmented body to twist so that it unerringly found Alexis's entrance.

For a moment, Alexis stiffened, looking down in horror at the thing crawling into her body. The moment passed and her eyes rolled up in her head. Her uterus contracted again and again as the motile tentacles caressed and probed at the sensitive walls of her birth canal. It drew itself into her waiting womb, overloading her nervous system with pleasure in the process. As the last of the module drew itself inside Alexis's body Kate disengaged their union and stood up.

The conversion module now nestled securely in Alexis's womb. It was a tiny biological factory whose first intention was to control a human female host, and then to convert her to most effectively serve the Race. Just as she watched Alexis writhe about on the bed, responding to the prickling sensation of the module's roots spreading outward into her abdomen, Kate came to a realization. It was an entirely new Race they were creating, reborn from whatever had come down in that pod. It would replace humanity, using it as raw material for a civilization which would spring from this world and eventually take the entire galaxy in its grasp.

Even though her consciousness was built from the rawness of Kate's mind, she was not Kate. She looked down at Alexis being converted on the bed and felt nothing but satisfaction. No conscience, no familial connection, no human morals restrained the new Kate's thoughts or behaviors. She would feed and reproduce, and the superior species would eclipse the inferior. When Kate began to get dressed again, leaving leaving Alexis behind to continue her transformation, the former detective smiled. Evolution. It was only natural.

Like Kate, Alexis's body also received the same pheromone enhancements when her brain was altered, gifting her with the power of suggestion and domination that had proven so successful in previous succubi. Her swollen vagina grew wet with her addictive honey while her already firm breasts swelled and minor imperfections vanished, leaving behind smooth tanned skin.

Once the module was finished, the new succubus opened her eyes, coming to her feet with fluid grace. Every inch of her body strummed with energy and new sensations. Despite the modifications, she was incredibly beautiful, an almost artistic combination of feminine flesh and cold metal as she stretched, growing familiar with the changes within her body.

Reaching out with her new senses, she felt the hum and pulse of the base wash across her, and information flooded through both her organic and electronic minds that quickly analyzed and filtered it, gathering data about her surroundings. In her mind, she heard the whisper of her creator, her master, her Queen. Obediently, she listened as instructions flowed in.

Ignoring the ever-present hunger which was now buried deep in the core of her being Alexis sat down to await her Queen's signal. Then the door downstairs opened, and in walked Rick. This male would be for Alexis to take and from which she would feed. That would allow her to create yet another module for the next female to be transformed into a succubus.

Rick heard a door open upstairs and glanced at the stairway. He was shocked into silence when a naked Alexis casually strolled down the stairs and headed right for him. Alexis smiled as she waited; obviously, her pheromones were beginning to affect him, his skin became flushed and his breathing began to quicken. He was also having a great deal of difficulty maintaining eye contact with her since his eyes kept straying downward to her pert breasts and then further down to her swollen Mons. Against his will, he was rapidly becoming aroused by her presence.

Alexis circled the room, her hips swaying seductively as she walked until she stood in front of her once father. Leaning forward, she favored him with a teasing grin. "I thought you might want to know that I am not Alexis, and Kate is not coming. She has already gone to spread the seed. She had given me what I needed to change from my original form to one more conducive for life in this environment. Thank you for bringing me here. I had never hoped to find such a perfect place to establish the new Nest.

"I will take what I wish, and if you fight me, you will lose. Every race has a weakness. Yours is your sexuality. You are slaves to your desire to reproduce. Look at you! I have my pheromones turned down as far as I can, and I can tell that you would like nothing more than to throw me to the ground and plunge yourself into my body. It's almost impossible to have a conversation with you humans.

"Enough talk!" Alexis stood up on her tiptoes and whispered in Rick's ear, her voice full of throaty lust, "I'm hungry and you're mine, body, and soul."

As the succubus fell to her knees before him, her nimble hands skillfully opening his pants, the helpless man let out a strangled moan of despair as she rubbed her thumb across his swollen glans before taking the length of his erection into her mouth. Mere minutes later, that sense of despair didn't prevent him from gripping Alexis's head in his hands and gently guiding the succubus while she bobbed her head up and down on his straining shaft. By the time Rick climaxed in her hungry mouth, that emotion was gone, replaced by lust and a driving desire to give everything he could to this gorgeous creature that he couldn't help but adore. He succeeded.

Across the room, the now docile girl, placated by the potent mixture of sexual pheromones and narcotics she had been forced to ingest, opened her thighs as wide as she could. She welcomed the module into her body, sighing with soft pleasure as it pushed its way up her canal and into her uterus. Before it reached her womb and seated itself in place, the attractive young woman had come to nearly a half dozen shattering climaxes as her subjugation proceeded. Once it had finished its work, the young brunette would leave home and quickly begin finding new hosts to convert into succubi. Like the other woman who had encountered the succubi, she would find her new work most enjoyable. As the young woman lay twitching on the floor, the invasion continued to spread.

Feed off of the men, convert the women into succubi, and spread out into space. They would convert this Galaxy into the new Empire. Kate was its Queen.
