Desolation: The Vanguard

Chapter II: The Twins

By Von Krieger

Li's sister moaned softly and shifted beneath her, responding to the soft kisses upon her breast. Li smiled as she sat upon her larger sister's midsection and began to caress her. Her employers stated that act she was performing was a sin twice over; one was not to engage in sexual activity with a member of one's own gender, and certainly not with a member of one's own family. It was a wicked thing, they said. It was a sin, a thing that would invite demons into your heart and soul, corrupt you from within until you were consumed with lust.

Of course they politely looked the other way, as the sisters had long since been demon-tainted (in the eyes of the Vanguard, anyway) and were made even more so with the cybernetic conversion program. They looked down on them for it, but then again there was very little that the vault-born did not look down upon them for. Li and Xi had grown up in the wastes, as they were called; though their ancestral home was lush and filled with living things, not the dead sand and rock common to so many places. Their ancestors had found the place by following a relatively pure river which flowed down from the single mountain, called Endless in the common language. It was named in remembrance of a place in the old world, the word for it long forgotten, but the meaning remained the same. It was named so from the endless font of water that spilled out from within, creating the pure, life-giving river that allowed plants and animals to flourish.

There had been an old bunker dug into the mountain, not the size of one of the great vaults, but there had been a great amount of goods kept there. The great warrior tribes of centuries past had required portable and plentiful food to keep its armies on the march. With the ancient magics provided by grand monsters of machines, they had sealed food into small metal cans and placed several in a box meant to be one meal. The bunker had contained the production facility, as well as a warehouse filled with crates.

The Kay Tribe had taken their name from these packaged meals, traded in caravans amidst the wasteland. They had even gotten the machines working once more, and with the bounty of the Endless Mountain they continued to help feed the wastes. Demons had tried many times to take the mountain, but it was protected; for the ancestors had brought their own demons with them, great protectorate spirits from the old world, who ventured into the depths of the mountain and called more of their kind to defend their followers. Thirteen Great Spirit Beasts made the mountain their home, and their children stalked the wilderness amongst the common animals leading their packs and herds, or acted as messengers from range to range amidst the solitary creatures.

Unlike the warrior tribes of old, her people only took what they needed from nature and nothing more. The tunnel villages dug in the mountain provided the warmth and shelter that was needed. The altered plants and fungi of a world soaked with magics and radiation gave them light and many crops, which they used to feed livestock, themselves, and those that eagerly sought the traded K-meals. There was plenty for all, and in time the population grew. Not wanting to overwhelm the generous mountain spirit and her thirteen guardians, the Kay took to having two children per couple. Those who desired more would have to venture out into the wastes and bring back something of value to the whole tribe. Some sought books or data discs and tapes, knowledge from before the demons came. Others negotiated trade routes with towns, cities, bases, and vaults that also had things to offer. Some merely left to explore the world, returning with maps of the altered land.

Xi and Li had left to explore the world on their own, allowing their family to grow by two with their leaving. When they had come of age, venturing to the shrine at the top of the mountain where the Great Spirits dwelt, they had been blessed greatly, marked as children of the beasts themselves, their destiny to find and protect a realm of their own.

Li's thick brush of a tail wagged as she ran her tongue over Xi's pert nipple. Until their visit to the shrine, the two had been identical twins, unable to be told apart even by their parents. They were close, as close as two people could be. But upon that day they had become more. Each sister had a bond to the other, an almost supernatural ability to tell what the other was thinking and feeling. At times they seemed to be almost one person in two bodies, which was rather how they viewed themselves. They were more than one being, but less than two. They could never explain the concept to others, but it was what they knew in their hearts to be true.

The blessings of the Great Beasts had made them randy, Li's blessing from the mischievous fox and Xi's of the virile tiger. Being transformed from mortal flesh to that like the Spirits dwelled in had only increased their libido. The unconscious Xi let out a soft cry as her sister suckled playfully upon a plentiful breast.

They had joined Vanguard, their skills as warriors and defenders of trade caravans well known. The order had not known that the twins were seeking out a place to be guardians of when they had signed on, but they had still yet to find that place.

Li's tongue traced over the dark markings that had appeared on her twin's skin, joining the many markings of favor from spirits they had aided over the years, as well as their patron's blessings.

Xi's arms and legs were adorned with beautifully detailed black stripes, the marks of the great cat that had recognized a part of its self in her. In time her hair had become a tawny orange, her eyes a deep feline green and slitted. Rounded furry ears adorned the top of her head, and a long tiger's tail trailed behind her. The marks upon Xi's breasts marked where the Vanguard had implanted the two large cybernetic computer components that served as the mind of the great creature that the two piloted.

They were experimenting to see how well one of the great demon-mechs could be piloted by two individuals who were used to being partners. The Hydra was the most complex of six mechs that had been created. Though the Minotaurus and the Lillith were heavier due to their thicker armor and stouter construction, and the Leviathan and Wyvern longer, the Hydra was overall the largest and most well armed of them. It was essentially a mobile weapons platform, designed for fast and rapid movement from location to location to keep enemies guessing. Six of its seven heads were capable of using their breath weapons akin to mortar fire, delivering acid, flaming napalm, and frigid liquid nitrogen down onto demonic foes from quite a ways away. The seventh head instead utilize thick saliva to spit a long line of conductive mucus, and then to send an incredible bolt of lightning down that line. Strange forces and spells went into the making of the gland that produced the substance, and given elevation and a lack of wind, the Hydra could get her central head to spit with a meter's accuracy at three miles from the target. Four heavy guns were mounted upon her back and shoulders, four miniguns and four missile pods adorned the end of her powerful tail, nestled within a spiked mace.

While the Hydra was modeled in part of the great multiheaded dragon, it was also in part designed from great lizards that had walked the planet in times beyond imagining. Bony plates and spikes from various species of dinosaur had been inspirations for the Hydra's construction, enhanced by biomechanical armor and spikes as well. Being hit by large demons from behind or above was the most common concern for the vehicle mounted artillery the Vanguard used, but the great dino-dragon was all but immune to these strikes.

Li giggled as she traced the seven pointed stars that encircled her sister's nipples, in addition thick, wavy lines extended several inches past the pointed arms of the star, and eighth line, straight, extended downward opposite the star's central point at the top of the breast. She knew it was the mark of their beast, the created demon-mech that they had grown quite comfortable in the past few weeks.

She could feel its presence, watching over them even now, though they were unable to see it. Despite the spirit's youth, Li knew that it was one of motherhood and maternity. When linked to the Hydra she could feel its pleasure at the two lives secured within. Small and comparatively weak and fragile, needing her protection to survive and to grow. The Great Spirit thought of its two pilots as its children. It had also marked each of the sisters in areas aligned with motherhood and fertility, and also where its components resided. Li's belly sported its own seven pointed star, with the same wavy lines and the single straight line that came to a point, like the Hydra's tail before the weaponry was added on. The only difference was that her star pointed downwards, and the 'tail' pointed up.

Li was not tall and powerful like her sister, she was shorter, her body more streamlined and lithe, and flat chested to the point of looking nearly androgynous. Her patron spirit had been the fox, and it had left markings upon her as the great tiger had done with Xi. Her hair was a shade in between red and orange, the hue of the fox fur that also adorned her pointed ears and her richly furred vulpine tail. Her markings were confined to her hands, feet, forearms, shins, and calves, like the sock-like black markings of her patron creature. Li's portion of the Hydra's processor core had been installed in her womb, which resulted in the appearance that her belly would forever appear to be near term with twin children dwelling within. It hampered her stealthiness and dexterity, but she was not a caravan guardian any longer. The Hydra did all the movement and heavy lifting.

She slipped a hand down to her sister's sex as her tongue moved upwards, seeking her sister's lips. As always the faint caress over her loins was enough to stir Xi from her catnap. Li could toy with her sister's breasts all she liked, even drive her to powerful climax, but Xi would continue to sleep through it. But the faintest touch to the core of her femininity would serve to awaken her from slumber.

Her larger twin sighed softly, returning the gentle kiss. Their lovemaking was always slow, tender, hours of building up to a single glorious climax. Their alterations, cybernetics mixed with demon-magic, assured that they did not need sleep. But the dream world was so fascinating Xi preferred to slumber and dream during whatever time she had to herself. But at night, in the bleak hours between midnight and dawn, those were the hours that belonged to both sisters, when they would share everything with one another.

"Father Tiger spoke to me from the mountains," Xi whispered to her sister, her powerful hands coming up to gently trace the black star upon Li's belly. "Something wondrous is to happen tonight, a gift from the Great Spirits to assure that many of their wicked cousins will be punished by us for the horrors that they inflict upon mortal beings."

"And how will we do that, dear sister?" Li said softly, resting her head upon Xi's ample chest.

Xi smiled. "Why, you do realize that we have thirteen benevolent yokai," she used the old word for demons, one with less negative connotation that the one in the trade tongue, "The six great beasts, and the seven who pilot them."

Li smiled as well. "I had, but until you mentioned it, I had not thought of its parallel to the mountain home of our kin and its spirits."

The tiger-touched twin merely chuckled, hugging her sister to her breast, "Tonight, I am told, we will become powers ourselves, no longer mortal spirits inhabiting demon's flesh."

"And how will this be brought about, my sister?"

"I am not sure, but I do not think it will mind if we continue our love making while we are waiting for it."

"I do not think so either," Li concluded, the twins meeting in a more passionate kiss.

-o-

Delilah stood in the shadows, her demonic form cloaked with the darkness. The scent of the Kay sisters was irresistible. They were twice marked by demonic forces, and that made them stand out like beacons in the night to Delilah's succubus senses. Their bodies entwining, two sisters pressed against one another, hands, lips, and tongues roaming over the other's flesh; this too had drawn the new demoness' attention. But it was not the so-called sin of the act that called to her; rather it was the intensity of the act. The emotion shared between the two sung its siren song to her, calling her to oversee the alteration of these two before any others.

She could not believe that the Vanguard had been so ignorant. She could sense new presences now, it was not quite sight, scent, or sound, but had components of all three. Using this new sense Delilah could feel the energy building in the room; hot, warm, lovely, and delicious. She basked in the glow of the twins' lovemaking, for the affection the sisters shared fueled the energy storm building around them as much as the carnal lust.

Oh how she longed to join in, but she was not the only demonic presence in the room. Though the astral form of the Hydra was half in the room and half out, the demon-mech's rear half residing in the storage room on the other side of the wall. Her many eyes watched over the room, some focused on Delilah, others focused on the beast's pilots in the bed. The many headed reptile knew what had happened to Delilah and what she had done to Shailai. The succubus could faintly feel each surge of pleasure the new demoness felt as she mated with her mistress the Wyvern, and she suspected so too did the Hydra. The demonic mech looked almost pleadingly at Delilah, wanting to grant her pilots the gift that Lillith had granted to the new succubus. Hydra was a new spirit, and she did not have the power that Delilah's love had bestowed upon her.

She smiled and closed her eyes, reaching out to the mighty presence. "Take all you need," she whispered. "Use my strength to grant them the gift we both desire for them to receive."

Delilah shivered as she felt some of her demonic lifeforce slither away. It was not an unpleasant sensation, for she had an incredible amount to spare and she gave of it willingly. She could see why some sorts of demons, the vampiric types, would greatly enjoy corrupting their victims with this method. It was rather effective; drain a mortal's living essence and then replace it with an equal portion of your own. Mortal agents and thralls could be created in this manner, just as long as the demonic force was not in dominance over the mortal.

The spectral form of the Hydra shimmered, granting her a little bit of solidity, but not so much as to prevent her from passing through the wall. She was just 'real' enough to touch those who she had marked as her own. The creature lowered her central head down onto the bed, her jaws opened wide. The six other heads extended their tongues, playfully licking and lapping at the twins. Li and Xi both cried out, quivering. Delilah recalled how wonderful her own deimomech's touches had been upon her body, and could only imagine what the twins were feeling now.

-o-

The Hydra crept forward slowly, her pilots slowly coaxed into her spectral maw. Li and Xi could feel a soft warmth surrounding them, but they could not yet see the source of the heat, nor where the soft, smooth caresses of pleasure over their bodies came from. As the warmth spread over their bodies, drawn deeper and deeper into their mech's mouth, they found themselves in a pleasant and lustful haze. They ground gently against one another, their loins forgotten. What seemed to give the most pleasure were the marks upon belly and breast, the places the Hydra had claimed as her own. She was not devouring them, oh no. A demon's anatomy was malleable; it was whatever the creature desired it to be. So if she desired her throat to lead to her womb, then so be it. There was nothing that stopped that from being true, save for the tiny expenditure of power that it took. She had longed for her pilots to be truly inside her, residing within her womb, not merely within the specially crafted chamber where they piloted her from. They were to be her children, her offspring, but in order to do so they needed to be truly reborn.

Hydra crept forward into the room, lifting her head to send her pilots on their journey from mouth to belly. She could feel her power building as she drew in the elements the two sported that granted her consciousness and control. Her tongue slithered between the twins' legs, caressing their sexes, further marking the pair, making them hers. With a gulp she drew them into her completely, closing her mouth and trapping them inside her. She could feel a world of potential opening up within her; a demon could do whatever it liked with its own body, provided it had the raw power to alter it. Her pilots had been marked twice now, a third time and they would be as her own flesh.

She fully entered the room, resting her forequarter atop her pilots' bed, curling her heads and tail around, drawing in her power fully to one location. Li and Xi cried out softly as the deimomech drew out the control components from each of them, adding her missing pieces to herself. She gave back in turn, knowing that her pilots adored their additions, loving the plentiful breasts and the big round belly that they had been given, made so wonderfully sensitive by demonic alteration. But the Hydra also knew that each sister had envied what the other had, wanting to have a generous bust and a round, pregnant belly of her own. It was quite simple to grant the desire, to give Li an enhanced bust, and to Xi a rounded, full belly. New markings appeared upon the skin of each sister, the same seven pointed star with wavy lines that symbolized the great Hydra. Upon Li the markings upon her breasts were turned 45 degrees inward, the long 'tail' opposite the peak point of the joining just below her sternum, making a Y shape with the mark already upon her midsection. Xi's mark was identical to the two she already sported; save for its location upon her navel, the symbol's tail pointing downward to her loins where small black marks had appeared.

Thrice marked, they were fully hers now.

-o-

The Hydra beckoned Delilah towards her, and the succubus found herself unable to resist the call. There was something the deimomech craved, something she needed, something that she fantasized about, and as such it stirred the demonic instincts deep within the new succubus.

Her crimson skin seemed to glow softly for a moment as the pilot drew upon her power to begin the alterations she would need to satisfy the massive reptile. Her loins began to ache and throb, leaking thick juices that glowed the hue of embers in a fire. She approached the creature's astral form as if in a trance. Delilah's taloned fingertips traced over the ethereal skin and scales, feeling them in all their wonderful sleekness even though they were not truly there. If she truly wished, Delilah could have walked right through the Hydra's massive flank, feeling nothing more than the slightest sensation upon her, like unseen cobwebs in a passage. But she wanted the Hydra to be solid to her, and so she was.

Delilah planted a kiss upon one inquisitive snout, gasping softly as others began to nuzzle her, soft, smooth tongues wider than her spread fingers exploring her demonic form. The Hydra's touch did not stir the same incredible sensations that contact with her own Lillith did, but they still were wonderful. The gentle touches of a somewhat shy, but eager lover. Heavy forked tongues teased her four nipples and her dripping sex. The merest touch about her womanhood made Delilah nearly fall to the floor in bliss.

The Hydra imparted a fragment of her dream upon Delilah, providing the instructions for alteration. Immediately Delilah felt her loins altering, the small nub of her clit beginning to swell and lengthen, her insides churning and shifting to provide the proper plumbing. While it was most certainly phallic in shape, as could easily be seen by its eight inch length after a few moments, the new organ Delilah sported was not a cock, not truly. It was not for filling others with her seed, but rather to provide a more effective delivery method for the demonic eggs that grew within her belly.

Delilah's new shaft drooled a generous amount of the same ember-hued fluid that seemed to have replaced Delilah's precum in her new demonic form. The Hydra seemed to enjoy lapping it up, her ethereal form shimmering, gaining a bit more color and definition to it, becoming less and less of an empty shell and more and more a creature of the astral plane. She would never be able to interact with proper humans, but she could likely... influence things. The outer walls of the Vanguard base were heavily warded to prevent such things from entering, but the Hydra was already inside.

A heavy tongue encircled Delilah's ovipositor, coaxing and caressing it into the size and shape the Hydra desired. Heavy and thick, about the length and thickness of Delilah's upper leg. It was most certainly not human; the thick knot at the base gave that away, as well as the strange, spade-shaped head, the rounded bumps on the bottom, as well as the three thick rings upon the length. With its sleek smoothness and onyx coloration it looked almost like some sort of obscene sex toy, another thing that was banned by Vanguard. Delilah couldn't even imagine what it felt like to have such a huge, wonderfully shaped thing inside her. But she wanted to, oh did she ever. She wanted to explore every single deviant thing that she had been told not to do for fear of drawing in demons.

She licked her lips at the thought of performing one more; bestiality. It was true that her Lillith was a beast, a four legged creature; but that was rather different. Delilah and Lillith complemented each other, they were soulmates. Shape did not matter between them, something greater than mere flesh and form. But the Hydra did not share such a bond with her. A gentle thrill ran through her as she thought about the situation. Demons drew energy and strength from human emotion; the guilt and shame some felt at having such fantasies, and the web of emotions woven by years of habitation in the Vanguard base left enough behind to fuel Delilah's further arousal.

The Hydra's tail curled around her, coaxing her forward as it lifted its rump, exposing the great demoness' sex. Like Delilah, the juices that showed the mech's arousal and lubricated her passage glowed softly. The hue was a pale blue, nearly a grey, contrasting a bit with the Hydra's gold and green scales. It felt wonderfully cool to the touch, whereas Delilah's had a pleasant heat to it.

"I gift to you, Mother Hydra," she whispered, "two of my eggs for your use. Bless your pilots, your children, as you see fit."

She relaxed, abandoning thought, acting only on the instincts that whispered to her, telling her of dreams, fantasies, desires, and sensations, telling her where her reptilian lover desired to be caressed, and what touches would most please her. Delilah had never felt as good in her life as she did at that moment, fully embracing what she had become. She was having the time of her life, and she wasn't even halfway through the roster of pilots yet. Mmm...So much to do, and so little time. But she would not rush through this night. Everything had to be perfect, be wonderful. It wasn't every night that you got to be reborn into what you've always wanted to be...

-o-

Xi let out a soft moan as she began to stir. She could feel the faint twitches of pleasure in her loins that always came after a night of delicious carnal embrace with her sister. But the pleasure felt different this time. It felt more intense, but at the same time more natural. Like this was what she had always been meant to feel, but the limitations of her body, mind, and soul would not allow it. She felt warm, safe, loved, but she also felt strangely alone and isolated. She reached out in the darkness, feeling for her sister, her lover, her other half. The movements were slowed, muffled, as if passing through water. Her fingertips found a more solid resistance in a smooth, curved surface. Xi pressed against it, but found it hard and unyielding, even to her powerful body.

Her other hand, her left, felt a bit strange, stiff and cramped, like it had been in an uncomfortable position for quite some time, or had fallen asleep. But oddly there was no pain or discomfort, just a strange feeling that things were not bending as they ought. She couldn't feel her fingers, now could she seem to make a fist. Though she could open and close her hand rather like a crab's claw.

Xi smiled as she realized where she was and what had happened. She had experienced this once before, long ago. She had gone to meet the Great Spirit Beasts and had been reborn, infused with a portion of their power.

The Hydra had given them her blessing, marked Xi and Li as her own, not merely with marks, but in their forms as well. Xi smiled, pressing her claws against the shell of her egg. The shell parted easily, and almost seemed to shatter as Xi pushed her way free of it. Blue-grey fluid gushed forth from the egg, clinging to Xi's body. She drew in a deep breath, even though she did not need to. She felt the warm air flow into her lungs, but it continued to flow, coming to a rest deeper within her belly within some unfamiliar organ. Oddly enough she also felt it in her left arm.

She looked down upon the limb to find it massively changed. Her jaw dropped upon seeing her left hand, no longer a hand. It was instead a second head, draconic, sporting the same horns and fins as the great Hydra. Looking upon it seemed to activate new senses within her, the emerald, slit-pupilled eyes opening. Its muzzle grinned as Xi found herself seeing the world through four eyes instead of two. It made looking over her altered form so much easier.

Everything was familiar, yet most of her had changed in some way. The markings upon her body, the sign of the Great Tiger, still adorned her skin, but they also marked her scales. Orange, black, and white scales adorned her body, covering from toe to knee, from fingertip to elbow, and from shoulders to buttocks and down her tail. Her tail too had been altered, transforming from its furred feline shape to a longer, thicker reptilian tail covered in scales, with only a strip of striped, spiky fur down the middle. Nestled within the strip were small spikes that grew in size the further up her spine they went, until they reached her head, becoming the foundation for a large crest that extended six inches outward from her skull. Her long hair still remained, as did her pointed, furry, feline ears. But a pair of spiked frilled had been added to the side of her head where her ears had once been when she was human.

Her face had changed as well, with a light dusting of small scales, almost like freckles. Small spikes encircled her eye sockets, a pair of thick, but short, horns growing from her temples. They were not yet the majestic horns of a great dragon, but in time they would. The thought spread a smile over Xi's short, blunt muzzle. Her face was not draconic, but it certainly was not human. It was a beautiful blend of both, taking what Xi felt were the best features of both and bringing them together, painting the union with the coloration and markings of a tiger.

She ran her right hand over the scales upon her left, both of her mouths smiling as she found them to have a velvety texture to them. Not quite fur, but a pleasant compromise between mammalian and reptilian traits. On the subject of mammalian traits, her own markers of belonging to that particular group had seemingly grown. Xi couldn't help but chuckle, she had always been fond of the computer core 'implants,' and found herself wishing on more than one occasion that they could be even bigger. Her breasts had been her favorite feature about herself, and Li loved to watch her sister play with them for her amusement. Xi's favorite portion of her sister's anatomy had been Li's similarly enhanced belly. Her smaller sister looked so sexy with a large, rounded middle, and Xi had spent many a night caressing and kissing the roundness as she pleasured herself.

Now she had her own roundness to enjoy, and she did so, running the forked tongue of her head-hand over the ebon marks of her 'mother,' the Great Hydra. The touch made her moan softly, causing her arousal to rise rapidly. That too was different; it seemed almost an external thing, a lustful ache building outside her body, rapidly extending further and further outward.

She looked down, but found her 'assets' to be an impediment. Xi chuckled, using the eyes on her 'hand' to view the alteration. Both of her mouths gasped at the sight of her altered loins, and they began to water at the sight of her bestial manhood. It was the size of her forearm, the thicker left forearm anyway, a deep black in color, emerging from a sheath at the base. She lacked a hanging sack, but she could see her heavy balls beneath it, extended outward partially from her body, but not entirely. Like the rest of her it seemed a mix between reptile and mammal.

The shaft itself was rather chimeric, rather equine in proportion and scale, but with a rounder, more human head. It was studded with feline spines, and sported the beginnings of a canine knot at the base. Xi could tell that while her body had all the outward appearances of being female, her sexual organs were entirely that of a male. It made her laugh, and also filled her with pride. Her people did not think of gender merely as a binary concept; there were other combinations out there, though rare in naturally born humans. But Xi had long since ceased being limited by what nature had gifted her for a body, having been transformed thrice over. Twice by Great Spirits and once by Vanguard scientists.

Xi was about to curl her tongue around her new length, to orally pleasure one new addition with another, but the surprised gasp of her smaller sister drew her attention elsewhere.

Li too stood in the ruins of her egg, similarly altered. She too had become a mix of her three aspects, human, fox, and dragon. Scales adorned her body in the same pattern as Xi and nearly in the same color, but hers were far more red than orange. Her tail lacked the central strip of bristly fur, instead sporting a fluffy, white tip, with long spikes hidden within, the tips just barely poking out of it. Like Xi, her breasts and belly had grown, the former having reached the size that Xi's had been before her enhancement, and the latter having grown even larger and heavier. The very sight of her sister made Xi's erection drool thick streams of glowing goo, oh how she longed to explore the new wonders that that had been gifted upon them. It was then that Xi noticed one more aspect of difference between the two of them; Xi's head-hand was on her left side, while Li's was one her right.

The two sister's came together, embracing one another, kissing in a way only they could; lips against lips and muzzle to muzzle. A double kiss, greater than anything anyone else could ever off them. They were a perfect match for one another, a perfect mirror. Li wrapped her left arm around her sister's neck, while Xi slipped her right beneath Li's rump, the two pulling her upward for proper lovemaking. With their large bellies and breasts, it ought to have been quite a chore, but somehow they managed. It was only a few moments before Xi's member was hilted in her smaller sister, her knot beginning to swell, binding them together in an act of passion as great as two lovers could ever hope to achieve.

It was then that something gave way inside of them, a wall that had been present all their lives, a wall with only a tiny window to the other side that could be peered though, and on a rare occasion reached through. Each sister's mind was fully open to the other, a union of mind and spirit to bolster that of their flesh. The contact was what each had craved for the entirety of their lifetime. Two souls joined eternally together, but until that moment trapped, despite their link they would be always apart had nature taken its course. But nature no longer had any say in the affairs of the twins. An idea sparked between them, not coming from one or the other, but from the union of both. There were pieces that were still Xi and pieces that were still Li, but as they had always known there was more overlap than there was individuality. Less than two souls, but more than one.

As they made love their bodies began to join together, as their minds had. There had always been a great power within them, but a power divided. As two became one the power flooded them, making the sisters more than the sum of their parts. Their bodies grew as they united, as skin became coated in velvety scales, as human features were replaced by draconic, as neck lengthened, as claws grew, as hands and feet became paws.

Four draconic heads cried out as pleasure rocked their shared form, the liquid flow of their uniting flesh and united souls as great as any sexual pleasure they could ever hope to experience. They grew and grew, their merged form twice as big and several times as heavy as their combined mass ought to have made. Within the room a new hydra took shape, her red-orange scales gleaming, her markings that of a demonic tiger, inverted upon her lower fore and hind legs where the coloration of the fox remained. She caressed her four heavy breasts with eager tongues, caressing her broad, egg-filled middle with one forepaw, the other encircling her manhood. Her frame was not quite quadrupedal, but also not quite humanoid. She could function as either if she so desired.

She felt a comforting warmth enfolding her, the embrace of her spectral mother. The Great Hydra curled around her daughter, her lover, four muzzles locking with the smaller hydra's, two others suckling hungrily upon plentiful breasts. She coaxed her child onto her back, lowering herself down onto the new hydra's aching member. The sisters cried out as their body shuddered, a fifth, central head emerging from their body. It was the sum of all that they shared, a consciousness that was neither Xi nor Li, but rather their true self, the single persona that the twins had always been facets of. They would never be apart again. Though the new hydra could divide herself into her component selves, the sisters were now forever united, brought together in one mind and one spirit, one that could inhabit two bodies. She didn't know the words to explain herself, she never did. The mortal tongue had no terms to describe a being that was at the same time one and several.

"We thank you, mother...," the new hydra's two outer heads said in unison.

"We are united in one, as we have always desired...," whispered the two in the middle.

"I am yours forever, your pilots, your daughter, your lover...," the center continued.

"Whatever you desire," all five finished in unison.

The Great Hydra purred softly, nuzzling her daughter's many muzzles with her own. She had no desire for ownership, for domination of her children, her lovers, her pilots. But there was one thing she desired, and desired more than anything.

-o-

Daughter Hydra cried out, her twin sexes linked together in climax, her seed flowing into her mother's eager depths. Though Mother Hydra's true body slumbered many stories above, whatever coupling took place between Daughter and Mother would have identical effects on both. With demons there was little divide between body and soul, any effect upon the astral form would be carried over to the physical. Even pregnancy.

Delilah chuckled to herself as she mused upon the topic. The room had grown increasingly crowded, filled with mating Mother and Daughter, serpentine heads and tails moving about with little regard for smaller sized voyeurs. The succubus walked down the hall, placing both hands upon her belly, the weight of her remaining eggs both a comfort and a burning ache within her. There were so many gifts that she needed to give and so little time to give them in. Perhaps once she had granted all the deimomech pilots the wonder of true demonhood, of being brought closer to the nature of the creatures that had become very much a part of them, Delilah would awaken her napping soulmate's astral form, drawing another load of seed into her belly, granting her another clutch of eggs to introduce comrades to the power that suffused every fiber of her being.

The thought made her chuckle, hour long pregnancies and rapidly growing eggs. It was something that was almost unheard of. The power to do so only seemed to be unlocked within a newly transformed human. But Delilah knew that if she so desired, she could be filled with eggs again and again, unlike anything she had ever heard of before, beyond even her seemingly instinctual knowledge of demonhood. Demons seldom parted body and soul, to explore in astral form. It left the body virtually helpless, and any damage taken upon one would be carried over to the other. It was little surprise that they would not investigate the wonders of this ability and power. A succubus would use it; of course, it made slipping into the rooms of lustful lovers so much easier, and kept them from detection.

Delilah shivered, a thick strand of lava-hued precum leaking from her ovipositor. Perhaps once her task was done she would see what it was like to visit others in astral form, perhaps causing a few pregnancies. The very thought filled her even more with lust and desire as she slipped into the next pilot's bedroom.

The more she experienced the more she craved, the more Delilah wanted to explore. Her body seemed to change a little more with each pilot she brought over into full-on demonhood, a little more of Delilah's fantasies and desires made real as she discovered them and could act upon them. She would never have imagined herself with a cock, invading women's dreams, seducing them, making their bellies grow with demonspawn. Of course she would gently peer into the minds of her lovers, assuring that such would be something they'd enjoy.

Delilah smiled as she sat down upon the bed, running her hand over the huge belly of the pilot through the covers. Delilah didn't even need to poke around in this one's thoughts in order to know that she would be more than eager, perhaps even outright thrilled, at the prospect.

After all, Technician Sardius had already willingly, eagerly, and by the sounds that occasionally came from her room while Delilah was passing by, very enthusiastically had filled herself with eggs.
