A medium sized space ship zoomed through the atmosphere of a lush, uncharted and presumably uninhabited planet, its sensors primed to its maximum as the ship scanned for an abnormality that it’s remote probe detected in a brief examination of the planet. The ship itself would easily house a full science crew, with multiple labs, fully furnished sleeping quarters and cafeteria as well as a sizable cargo hold to contain whatever of value is discovered, belonging to the U.S.A., or United Science Association. It’s crew, however, is worse than skeletal, crewed by only one person. Known commonly by her moniker, the crazed researcher, Cassandra was too focused on her own research that she didn’t even notice the various notices sent by her former boss about her dismissal from the company and demands to return the now stolen ship, at least till all long range tracking was accidentally disabled when she piloted her wayward ship through an asteroid field many months ago.
 
 
The Eccentric researcher had been jumping from planet to planet, searching for anything strange, which led her to her current location. She swept her short, black hair out of her focused green eyes as she looked at the screen, grumbling about cutting it again before turning her attention to the work before her. An unidentified alloy had been detected in surprisingly high quantities on the planet, and her insatiable curiosity thus brought her in search for the reason.
 
 
Minutes pass, and Cassandra’s eyes widen in awe at the source of the abnormality. Hidden in the vast jungle was a metal ziggurat, clearly religious in nature and made completely of the mysterious metal alloy. Excited, the researcher set her ship’s autopilot to land while she rushed off to get dressed in her environmental suit, squeezing her shapely body into her skin tight suit, before donning the bulkier Hazardous Environment suit, the latest in U.S.A research tech. It’s more of a safety precaution more than anything, despite all scans of the planet deeming it habitable, the inside of the ziggurat was unknown, and for all she knows could be filled with toxic fumes.
 
 
The sound of crushed and snapping timber fills the air as the heavy ship comes in for a landing, smashing its way through the foliage with little care. When the landing gears finally reach solid ground, the cargo bay opens with a loud hiss, and Cassandra steps out, walking slowly in the heavy suit towards her destination, the doors closing behind her automatically. It takes a good 30 minutes of walking before she is even at the ziggurat, the black metal sheen making an ominous sight and making the moulded murals depicting sacrifices all the more foreboding.
Cassandra, however, pushes on, ignoring the various scenes depicted, even as the scenes of sacrifice slowly turn to those of smaller humanoid beings worshiping a much larger creature, while she walks past many human skeletons, the quantity of bodies increasing as she gets deeper. Slowly but surely, Cassandra trudged onwards, and eventually made her way to the inner sanctum of the ziggurat, so deep that her wrist mounted computer can’t even connect to her ship computer.
 
 
When Cassandra pushed open the heavy doors to the inner sanctum, her eyes widened in surprise at the very first thing that caught her eye, a massive corpse of a creature, clad in sleek black chitin, looking vaguely humanoid and covered in many wounds that eventually lead to its death, three of its four arms sliced off, its long tail laying to the side of the room and its head completely removed and missing. Around it were many primitively armed human skeletons, having fallen in battle and judging from the various murals, they likely were protecting the black creature from whatever slain them all. Cassandra sighed as she looked at the sight before examining the creature closely, lifting its sadly hollowed out and light body to get a better look. That’s when she saw it, a fleshy, pulsing egg hidden by the creature’s form, the size of a large urn with four closed petals at the top, perhaps laid as the creature lay dying to continue its line.
 
 
Excited at the possibility of researching this unknown species, Cassandra went to work removing the egg from the floor, but the moment she touched it, the petals began to spread open, revealing the living creature within. Unable to hold back her curiosity, she leaned over the edge, and saw a spider-like creature looking back at her. It takes its time climbing out of the egg, stretching its eight spindly legs as it swishes its long tail around, the two fat sacs at its side pulsing as it looks at the researcher despite having no eyes. The creature itself is quite big, about the size of Cassandra’s torso. Cassandra squeals in excitement, seeing the creature being curious and non-hostile, and slowly begins to reach out to pet it. The creature lets out a strange sound, but sounds pleased as it is patted,not doing much else except observing the one before it.
 
 
--------------------------
 
 
Of course, Cassandra brings the creature back to her ship, finding that the egg had melted into itself in the meantime. The creature wraps itself around Cassandra’s chest, using its tail around her waist for extra support while its long legs hold itself against her body. It was then she saw the rather erotic sight of its under belly, looking strangely similar to a human female’s pussy. Feeling it rub against her as she walks and unknowingly affected by the creature’s pheromones that managed to pass through her suit, she can feel her arousal rising, and by the time she is back in her ship, she was panting heavily, eager to take her suit off and work away the intruding lust.
 
 
 
 
The moment her suit hisses and begins its removal procedure, the creature leaps off her body and sits by a corner, watching Cassandra as she removes her environmental suit, and then the skin tight suit beneath. Now unprotected by her suit, she feels the full effects of the pheromones, and by the time she peels off her skin tight suit, she is already drenched in arousal. Unable to take it any more, she almost rips off her clothes, stripping her body as she lays on the hard metal to pleasure herself, her mind too clouded by lust to notice the creature approaching.
 
 
Moans of pleasure echo in the ship as Cassandra slid her fingers into her moist slit, only getting four thrusts in before she felt the creature’s legs touch her hips, a fleshy tube extending from its under body slit. Without thinking, she spreads herself with her fingers, hungry for whatever the creature is offering, and cums as she feels the fleshy tube slide into her pussy, feeling it go deeper into her moist depths as the creature wraps its legs around her hips, pushing it as deep as it can go. Orgasm after orgasm rocks Cassandra’s mind as each pheromone induced thrust sends her over the edge, till her body is loose enough to fit the single egg that the creature is carrying. With one final thrust, the baseball sized sphere begins pushing out of the creature, spreading Cassandra’s lower lips with another mind shattering orgasm, and slides itself into her awaiting womb, making a sizable bulge in her toned belly. With the deed done, the creature falls still, as Cassandra finally passess out from her multitude of orgasms.
 
 
--------------------------------------------
 
 
Cassandra awoke on the cold hard metal, her body slick with the juices of her sexual encounter, groaning as she looked around. The first thing she noticed is the cold remains of the creature beside her, shriveled up like a dead spider on its back. The sight caused ehr to panic, but as she moved to it, she felt the weight in her belly. The egg that the creature had pushed into her body as its final act. With a sigh, she patted her belly, feeling the egg pulsing with life. With little else to do, she decided to go to her lab, casually wondering why she even bothered with clothes when she was by herself, finding her nudity strangely liberating. Scanning her body, she finds the creature growing within her womb, and her equipment warns of unknown hormones being introduced into her body by the creature. However, she pays it no mind, and begins keeping a log on the changes to her body as the creature grows within her. Meanwhile, since there is little else left on the planet, Cassandra lifts off, deciding to allow her ship to float in space away from any possible predators that might have returned to investigate her ship.
 
 
Days pass, and eventually, the egg hatches, though not before growing to the size of a football. Cassandra moans as she feels the long, snake-like creature exit its shell, wiggling around in her sensitive womb before it relaxes within her. Upon further examination, the creature attached itself to her womb, akin to a child to its mother, and it made Cassandra excited to see the creature live and well. She did notice changes to her own body as the days went on, her breasts becoming heavier, and her clit becoming bigger, with two bumps close to the bottom, making it look almost like a penis. Her belly continues to grow too, as the creature matures within her and makes her look fully pregnant, which she clearly was at this point.
 
 
---------------------------------
 
 
It is a month since her sexual encounter, and Cassandra’s body continues to change, her heavy breasts now leaking milk, and her clit now a full on cock, with a set of heavy balls covering her slit and her belly massive with visible bulges of the ridges and limbs of the creature pressing on her fleshy walls. She didn’t mind the changes though, enjoying the gifts her child gave her. Cassandra was doing another routine check up on herself when she suddenly felt the creature shift, and begin to wiggle more, before her water broke. With a cry of pleasure, Cassandra laid down on the medical bed, and spread her legs, feeling the creature already beginning to push its way out of her surprisingly stretchy womb, thin arms grasping at her legs to pull itself out of her moist womb. Cassandra cried, feeling only pleasure from what would be a very violent birth, and cumming as the last of the creature pops out along with its afterbirth. The creature was as big as she is, looming over her as she recovers, looking alluringly feminine with two soft mounds on its chest ,its slit clearly visible.
 
 
The newly born creature flexes its four arms, testing its body before it leans over Cassandra, bringing its maw to her exposed breasts, and with a second maw within its mouth, begins drinking from her heavy breasts, nuzzling up against her softness as it suckles. Cassandra coos as she pats the creature’s elongated head, feeling the cool carapace in her hands, wondering how she even birthed such a beautiful being as she felt herself get emptied with surprisingly efficient movements. Soon, Cassandra’s breasts are empty, and she has recovered enough to move, the creature nuzzling up to her like a loving pet. She would continue to tend to the creature, documenting its growth and any changes.
 
 
-------------------------
 
 
Cassandra continued to observe her body as time went on, and found pleasure in experimenting with her own body. Curious about her new found stretchiness, She slowly pokes a finger into her nipple, finding that it slid in easily, dribbling milk onto the floor. She continues to push more and more, till her whole fist is in there, letting out a cry of pleasure as she pulls her fist out with a wet pop. She then examines down there, feeling her cock and shivering from its sensitivity. She then glances at the creature, who had been by her side all this while, enjoying the show or so it would seem, and looks down towards the inviting slit between the creature’s legs.
 
 
As if it knows what Cassandra wants, the creature lays back, and spreads its slit with its fingers, the deep green flesh inviting her towards it. With her cock hard, Cassndra took the invitation, and thrust hard into the creature, feeling the fleshy walls squeeze around her virgin cock. With all her inexperience with the new member, she came soon after, pumping seed directly into the creature’s womb, who nuzzles lovingly against Cassndra;s cheek. However, Cassandra was not done, and soon begins thrusting again, eager to fuck and fuck the creature till it gives her a whole load of eggs...
 
 
---------------------------
 
 
More moths passed, and the creature had changed drastically. Its elongated head had spread out to become a magnificent crown, and it’s size had increased to the point it would be almost three times Cassandra’s height if it could stand up properly. Due to her ship running low on supplies, Cassandra had landed her ship on another indocumented and uninhabited planet, the creature the key to her protection and survival. With much more room, the creature had terraformed their landing zone, making more or less a nest for them to live in, the walls covered in fleshy growths that are surprisingly comfortable, and also deterred predators from approaching.
 
 
The creature had also begun laying eggs like she wished, likely waiting for a proper nest before doing it.Cassnara noticed they were much smaller than the progenitor’s egg, the size of a rugby ball. She eagerly watched it hatch, her new cock hard and pussy moist at the thought of what is to come. Sure enough the spider-like young came out of the eggs, and she spread herself to allow them entry, crying in pleasure as she was swarmed by them. Her heavy breasts, modified by the hormones, are easily penetrated as her pussy and cock are also filled, their long fleshy ovipositors bulging out her flesh with their numbers. The creatures quickly deposit their table tennis ball sized load into the living nest that is Cassandra’s body, filling her up before shriveling up, the next in line pushing the corpse away to get access to her. Soon, all the eggs are empty, melting down to join the comfortable flesh around them, Cassandra’s body heavy with eggs as the progenitor comes over, letting Cassndra suckle on the creature’s milk filled breasts as she recovers, feeling the eggs jostle around within her heavy balls, breasts and womb.
 
 
Hours pass, and she could already feel the eggs hatching, the snake like young eager to be free. With a cry of pleasure, She cums, shooting the young out of her heavy balls along with a good amount of seed, and watch them slither off to mature. Those in her breasts however are more than happy to stay in her, drinking the milk till they are full before slithering out of her nipples, as do the ones in her womb, a shiver of pleasure running through her body as they slowly slide out of her body, less explosive than the ones that were squirming in her balls.
 
 
After the new young matures, the progenitor remains at the nest more often, cuddling with Cassndra, enjoying her company while the young hunt for food and water, keeping them all fed and happy. Despite it all, Cassandra still keeps a log of her events, happy to have found a good environment for her young to live and grow… though at the back of her mind, she is already having plans of leaving, not to escape, but to bring someone else along....
