Page 1: Jean finally arrived home, exhausted from another week in the laboratory. She was so tired of the workload she had to put up with while the other employees laughed or flirted in the breakroom and around the water cooler. Just because she wasn’t as curvy or as confident didn’t mean she deserved to be pushed around. Of course, they always got her to do more work in a passive aggressive way. “Jean, can you take care of this analysis of mine for me? I have to leave early today.” “Jean, can you finish my report for Friday (on a Thursday evening!) I have to leave early today for an errand.” Week after week, on and on the excuses went. Why didn’t she just say no? It made her so mad! Jean sighed, at least it was finally the weekend. Taking most of her clothes off, Jean put on her comfy robe before realizing she’d worked up quite a thirst venting her work frustrations to the cosmos. Reaching into her bag, she pulled out her water bottle from work. Immediately she noticed the color was off. Was this some sort of prank from people at work!? If so, they were going to hear about it on Monday! She’d go right to her lab manager! Carefully opening the bottle, Jean looked inside. Almost instantly the black fluid started flowing out. Afraid it would ruin her bed sheets; she reached out to stop it. The slime like substance oozed over her hand and started to pool up in the center before growing larger. She’d seen some strange substances in the lab, but never anything like this. When the substance refused to stop oozing out, she attempted to close the bottle with the cap to stop it, but a deep “HEY!” echoed through the room. Shocked, Jean looked around, but after seeing no one, she turned back at the ooze which, to her surprise, had now formed a small, toothy head with two little white spots for eyes. Jean blinked a few times and then stared for what felt like ages before the deep voice once again echoed, “You got a staring problem?”

Page 2: Shocked, Jean shook her hand, attempting to dislodge the slime, but it refused to release. As she flailed her hand around, the deep voice spoke again, “AYE aye aye, relax! You’re giving me a headache.” Breathing heavily, but trying to calm down, Jean looked back at her hand and sure enough that little toothy grin looked back. “H-hello, who are you?”, Jean asked nervously. “H-Hi there,” the ooze replied in a mocking tone, “I d-d-don’t have a real name, they don’t give those out to lab experiments.” Instantly annoyed, Jean’s face soured. Great, even the lab experiments were being disrespectful to her now. Jean thought for a second, about the situation. She may be a pushover, but she was anything but dumb. This, whatever it was, was clearly a stowaway, so it was time to do a little fighting back. Changing her tone, Jean replied, “Very well, Mr. No-Name, in that case, how about we take you on a trip back to the lab to get you one?” Slight panic showed in those beady little white eyes as it looked around unsure what to do. “Okay, okay, I’m sorry,” its deep voice responded, “Maybe we got off on the wrong foot. In all honesty, no one has ever asked me my name, so I didn’t know how to respond. I don’t really have one.” Surprised, Jean replied, “I guess we’ll have to give you one. How about, Eddie?” The slime rolled its little white eyes, “Lame.” Unperturbed, Jean continued, firing off names with the slime responding to each. “Venom?” “Too Edgy.” “Brock?” “Nope.” “Sally?” “What?” Jean rapidly laid out about 20 names, each getting turned down by the slime before it finally interrupted, “Look, look, relax, we’ll workshop it over time, okay? I want to offer you a deal.” Surprised by the conversations change in direction, Jean only responded with, “I’m listening.” The slime made a throat clearing noise, “I’m a genetically enhanced, military grade symbiote, designed to augment with humans to make them stronger. As I heard from your argument with… yourself, you could use a confidence boost.” Jean blushed, looking away for a second, but turned back when the symbiote continued. “You need me to get this and I need a human to live outside the laboratory,” the symbiote said. “I can help you get all the confidence and even the looks, you’ve ever dreamed of,” the symbiote finished. Jean sat in thought for a few seconds so the symbiote continued, “Look, I know its sudden, so you don’t have to make a….” Jean cut off the symbiote, “Deal.” The symbiote tried to continue, “…choice right now, we can… wait what?” Jean sat up straight and replied again, “It is a deal.” Surprised, the symbiote, shook its head, before continuing, “O-okay, lets get to it then I guess.” Jean responded, mocking the symbiote’s surprised stutter and with the sassiest face she could said, “S-Sure thing.” The symbiote groan at being beat by its own joke before instructing Jean to put its bottle down on the bed and lie down. “Will it hurt?” Jean asked a little concerned. “On the contrary, it should feel rather nice,” the symbiote said. “Should?” Jean asked. It was the symbiotes turn to blush. Even though its colors were all dark, Jean could have sworn she saw a hint of red flash in its little cheeks. The symbiote looked away before responding, “It’s my first time merging with a human, so I’m not sure, but I’ve heard results from the scientists.” Feeling better, Jean lay still as the symbiote slowly oozed out from its bottle home. More and more poured out like a bottle clown car as it slowly creeped up her lower legs. A warmth spread its way up her lower body, settling between her legs. Jean bit her lip, savoring the new feeling.

Page 3: Jean laid back, watching the symbiote slowly climb up her legs. Every slippery goo like inch brought more satisfaction that made her breathe heavily. Her nipples felt surprisingly tender and her bra was feeling as though it was squeezing too tight, so Jean made the decision to remove it. I wasn't like the symbiote hadn't already seen her more private bits. Curious about how the symbiote could alter her body’s appearance, Jean spoke up asking, "How will you be able to change my physique if you are only on the outside?" There was silence from the symbiote before it spoke, "From that, I've heard from the other scientist, I'll have to go... inside to merge." Jean blinked a few times, unsure about how to respond, but the feeling of the symbiote slowly coating her body felt so blissful she could only imagine it inside. After all, she was a scientist, and experimentation was part of her life. "Inside it is then!" Jean said, accidentally sounding a bit more excited than she anticipated. The tongue of the symbiote stuck out as it responded with a nod and began building up right in front of Jean's crotch. She was already dripping wet from the experience, but she imagined that wouldn't be necessary in this case. More of the symbiote spread out over her bed before the bit building near her pussy finally pushed against her tender lips. Jean let out a little gasp as it touched and the symbiote paused. It looked toward Jean who bit her lip, trying to hide a smile, and she nodded back. Acknowledging her approval, the symbiote slowly pressed its way inside, lightly parting her lips at first. It's veiny outside felt amazing as it slowly slid its way against her vaginal walls. The pleasurable feeling against her body began ramping up tenfold as it pressed more and more inside, slowly spreading her pussy lips wider and filling her up. The veins of the shaft pulsed over and over as more pushed inside and slowly absorbed into her body, turning her on more with each passing second.

Page 4: As the symbiote continued to spread up her body and fill her vagina, Jean couldn’t resist changing to her favorite position and turned over on to her hands and knees. The symbiote, taking this as an invitation, to proceed to the next level pressed itself against Jean's anus. Surprised, Jean quickly spoke, "That's the wrong Ho oooohhhl… my goodness..." as the symbiote slowly slid inside. A quivering orgasm rippled through Jean's shaking body as the symbiote began spreading inside filling both of her holes at the same time. She could feel her body changing faster as it did, with her breasts and hips both expanding and starting to give her a curvier appearance. Jean's breasts expanded, filling with milk to a point where the pressure that had built inside them was intense and needed relief. Before long the pressure became too much and milk gushed and sprayed from her nipples only to be absorbed into the symbiote below. The feeling of her body stretching and growing, while merging with the symbiote at the same time sent constant waves of orgasms through her that built even stronger as the symbiote pushed more of itself inside. Before long with her insides filling, symbiote slime started leaking from her mouth as her tongue also stretched and grew as the symbiote passed over it.

Page 5: Jean's body continued to stretch and grow as the symbiote slowly absorbed into her genetic makeup. The feelings of pleasure with each wave of growth were nothing short of the most incredible orgasmic experience she’d ever had. She could feel every throbbing inch of the symbiote stretching her vagina as it pushed more of itself in to be absorbed. The symbiote had now emptied itself from the water bottle and had spread throughout the room. Tendrils wrapped around her limbs and suspended Jean in midair like a floating sex chair. Her hips rocked back and forth savoring the feeling as her expansion came in waves, each bringing a torrent of orgasms crashing through her body. Moaning and breathing heavily, Jean managed between breaths, "Please more, don't stop!" A deep rumble of agreement was all she heard in response, as the symbiote seemed to be enjoying itself as much as her as the two continued to merge.

Page 6: As Jean merged with more of the symbiote, the limited slime of the tendrils became no longer able to support her and lowered Jean from her lofted position. Symbiote goo now dripped all over her skin as it continued to spread over her, slowly covering her body. Her swelling breasts, that were now producing milk at an alarming rate due to the merging, started being filled with symbiote slime instead, expelling all her milk as quickly as it was produced. There was little Jean could do, save enjoy the ride. The more the symbiote spread over her, the stronger the pleasures became and the harder the orgasms hit. Opening her eyes and looking through her glasses, Jean’s vision was now suddenly blurred which confused her. Feeling her confusion, the symbiote took a second from its spreading to gently remove the glasses. Jean blinked, her vision sharper than it had ever been, another advantage to the symbiote genetic enhancement merging. Before Jean could mention anything about it, the symbiote returned to its task, pushing more of itself into Jean’s body to be absorbed. A quick gasp followed by a blissful moan was then the only response from Jean as her body continued its transformation.

Page 7: With the pleasures surging through her body, Jean once again put herself in her favorite position, giving the symbiote permission and easy access to merge more intensely. Between moans of delight Jean spoke up, “More symbiote, please push deeper inside!” The symbiote took some time to appear from its slime on her body. Looking into her lustful eyes, the symbiote could tell she was drunk with pleasures and upon inspecting her growing body responded, “I’m unsure how much more growth your body can take.” Jean shook her head panting, “More PLEASE! I can take it all!” The symbiotes tongue twisted itself around hers, both looked into each other’s eyes. The symbiote could see her conviction and feel her strengthened resolve to see the transformation to completion. The deep rumble of the symbiotes voice echoed through her head, “Very well, it shall be done.” Dual tendrils of symbiote pressed into her holes once more flooding inside her, swelling her belly, breasts and butt way faster than she’d yet experienced. The result was an overwhelmingly strong wave of orgasms that nearly caused Jean to collapse, but she held strong. Before long the milk leaking from her growing breasts was swapped out completely for symbiote goo as her body reached its absorption rate limits. However, just like Jean had said, it still continued to absorb and transform. Orgasm after orgasm slammed into her body, causing it to shake and quiver so blissfully it took her breath away. Jean’s moans of delight echoed through her home for hours and hours as more of the symbiote continued to merge with her.

Page 8: Jean’s body had stretched and grown exactly where she’d hoped it would and now sported a massive set of breasts with the thickest thighs and ass she’d ever seen. Her belly, having shrunken down to its normal size after absorbing what was inside, now revealed an impressively strong, yet thin, shapely waist. Yet another advantage to the symbiotes physical enhancements. The last of the symbiote puddled between her legs as she knelt on the bed, hefting her massive breasts up and down, feeling their weight. Smaller orgasms, still rippled through her body as it continued to expand, absorbing the last of the symbiote, as their merging was nearly complete. Even through she’d just been slammed by hours of body shaking orgasms, Jean felt like she was ready for another round. Her strength was like nothing she’d ever known and her stamina could match it. “What do you think?”, came the deep echoing voice of the symbiote from inside her head. “It’s more than I could have wished for,” Jean replied still in awe, “It’s perfect.” A rumble of agreement emanated from the symbiote as Jean started to test out her dexterity with her new long tongue. Stretching it out from her mouth, she wrapped it around her nipple, while squeezing her breasts. Milk once again sprayed out sending a wave of pleasure through her. Jean moaned, squeezing more as the last of the symbiote continued to merge with her. Her new body was absolutely perfect and she couldn’t wait to show it off to the world.

Page 9: As the last the last of the symbiote merged with Jean, her body slowly reached an equilibrium and its orgasms began to slow before finally stopping. The difficultly was that equilibrium didn’t mean sexually satisfied. Rather it felt as though her whole body was about mid-way into cresting into a powerful orgasm and couldn’t relax. Jean panted, as she slowly got her breathing under control, it would definitely take some getting used to. She desperately needed a partner to please her and the symbiote inside her was resonating similar feelings. She’d have to go back to the lab to retrieve another symbiote sample to share it with someone else, otherwise no one could possibly be on her same stamina level. The symbiote, who was a bit averse to returning to the lab, eventually reluctantly agreed with her plan. “Can you shape yourself more like clothing?” Jean asked inquisitively. The symbiote grunted in response before adding, “To a degree, I think, as long as I know what you have in mind, the rest of me, I’ll have to hide inside.” Jean bit her lip at the thought, but only nodded before adding, “I can take it.”

Page 10: The two started disguising themselves as best they could. The symbiote managed to shape himself as long gloves and leggings with most of his form. Jean took a few seconds to remove the lenses from her glasses so she could use them. Next, she grabbed an outfit she’d never dreamed of wearing in public with her previous curves, but now, it would work perfectly, even if it would be stretched to its limits. Her new size would be impossible to hide, but she’d just have to hope to avoid as many people as possible. Maybe they’d arrive late or enter when everyone took their lunch. With their anything but flawless plan in place, Jean entered the high security section of the laboratory. She waited patiently for everyone to evacuate Lab SV1 before she slipped inside. She stopped over by where she’d previously been working and saw the empty flask labeled Specimen - 001. The mild anxiety emanating from her symbiote told her that had previously been his confining home. “Don’t worry,” Jean reassured, but just as she was about to continue, a voice Jean recognized broke the silence. “Jean! There you are, I didn’t see you this morning. You, look… different?” It was Julian, someone Jean admittingly had a mild crush on for some time. She always felt the feeling was mutual, but neither had ever been brave enough to make a move. As Jean worked to grab Sample - 042 and move it to a water bottle (hey, it had worked before) she also worked to distract Julian. “Hey Julian. Different you say? What’s so different?” she responded while slowly swaying her hips back and forth and humming. Caught off guard, Julian knew there were several easy and obvious answers, but played the safe card, “You… uhh… dyed your hair! It looks nice!” Jean had finished her symbiote extraction but needed to change the computers data to reflect no missing samples. The was also computer, that Julian happened to unfortunately be heading right for. Suddenly the perfect plan popped into her head and a smile spread across her lips. “He’ll do perfectly,” her symbiote’s voice echoed through her mind as he agreed. Standing, Jean started walking toward Julian at the computer. He looked back as he saw her approaching. Jean’s hip swayed sensually back and forth and her massive breasts bounced with each footstep. As she closed the gap, Julian turned around waiting for her response to his hair comment, struggling to keep his eyes on hers. The closer Jean got, the more aroused she became which in turn caused her symbiote to start to lose control and slowly spread out. Feet became inches between them before Jean finally responded to Julian, “Ah, yes, my hair,” she smiled as she playfully twirled it in her fingers, “Is that… all?”

Page 11: Julian bumbled some words as Jean’s breasts slowly pressed into his chest, his eyes straining to remain locked on hers. Admittedly, she hadn’t thought to get this close, but her plan was working. Her left hand quickly pressed a few keys on the console, adjusting the sample manifest, before turning her attention back to her next experiment. Julian swallowed nervously as Jean reached up, brushing her hair behind her ear and seductively parting her lips. Her eyes darted to his lips and then back to his eyes before she spoke, “Julian, I need your help with a new experiment.” Jean could barely contain herself. If she had his permission, she’d rip his clothes off right now, but she just needed to restrain herself a bit longer. “A, um, experiment you say? Where at?” Julian responded, clearly flustered. Jean exhaled, pressing in a little closer, struggling to hold back her desires. The symbiote inside her also struggled, slowly spreading further over her face. “My house, right now, everything is already set up,” Jean responded seriously, “I was working over the weekend and hit a major breakthrough, but I need you… your help.” Julian was really struggling to keep his composure, but managed a timid, “O..Of course, let’s go.” Pleased, Jean quickly pulled back from Julian who almost immediately collapsed to the ground. “Excellent!”, Jean said hearing Julian release a shuddered chest full of air as she turned to walk toward the exit. Jean turned back to see him still at the computer quickly trying to gather his composure. Julian guessed her question by preemptively answering, “I’ll.. I’m right behind you.”

Page 12: As the two scientists arrived at Jean’s house, both exited their respective vehicles and headed inside. Julian was still unsure what to expect or why Jean had been working from her home, but he was definitely set on finding out. Not to mention, if it has something to do with her sudden change in appearance. Jean only asked Julian to follow her as she made her way through her home. Julian’s eyes struggled to pry themselves away from her swaying hips, he was thinking with what was between his legs again and that certainly wouldn’t get him the answers he needed. Or so he thought. Jean reached out with her hand and gently pulled him into her bedroom. Her breathing was rather heavy for the lack of effort as if she was holding something powerful back. “Jean, what’s going o… ,” Julian tried to ask before Jean gently help a finger to his lips and replied, “I will show you.” She was incredibly close again, her perfume filled Julian’s nose with the scent of sweet flowers. Jean’s breathing intensified as she slowly began to undress Julian. They’d known each other for a long time and he’d always regretted not pursuing a relationship with her further, but now it was suddenly happening so quickly. As she unbuttoned his shirt, she gently pressed him back so he’d sit on to her bed. Looking up, her eyes were filled with a lust like no other and a black ooze slowly began forming around her body. Julian had seen it on her face in the lab, but had been too distracted to investigate further then, but now it was impossible not to. “Is that, what I think it is?” Julian asked. Jean nodded before motioning toward the bottle she’d set on her bedside table and replying, “I brought some for you as well.” Jean continued undoing each button as more of her symbiote spread out over her body, her lustful breathing audibly louder. “Is it safe?” Julian asked, as Jean gently pushed him back on to the pillows and began removing his belt and pants. A soft hmm was all Julian heard for a while before Jean finally replied, “It certainly feels safe, but we always have pushed the boundaries with science, haven’t we?” Julian couldn’t deny this, they always had, and he trusted Jean more than anyone else at the lab. Hearing her answer, Julian relaxed, lying back, which elicited a smile from Jean as she finished removing the last of his clothing before removing her skirt. Straddling his legs, Jean grabbed the bottle, removing the cap, but paused just before she poured. Their eyes met and her look made Julian realize she was waiting for his approval. He nodded and a smile spread across Jean’s face. As she began to pour, a warmth spread out over Julian’s body. It was a feeling like nothing he’d ever experienced. Immediately he felt he was getting hard and pre-cum dripped from his tip. Jean’s breathing escalated once again, sounding more lustful than ever. Julian could feel the liquid spreading up his back and gradually he started hearing what sounded like a second female, besides Jean, breathing in his ear. Pleasures started building inside him shockingly fast, Julian wasn’t sure what was happening, but he was certain he was in for the ride of his life.

Page 13:
The farther the symbiote spread over Julian the more turned on his whole body felt. The pleasure came in waves and eventually each wave came with changes that were very new to him. Slowly Julian’s body hairs began to shorten and his skin felt softer. Each wave also brought stronger feelings of pressure building up in his pectoral region as well as his hips. The pleasure that surged through him as both of these areas began to expand was incredible. Soon he wanted nothing more than the next wave to arrive. His shaft continued to get harder and harder and soon was growing in size as well, way beyond what it was previously. Julian glanced at Jean, who’s body was almost covered in her symbiote. Lustfully she looked at him before moving forward and sliding his growing shaft between her curvy ass. Jean, now panting with pleasure, slowing began moving her hips up and down sliding his cock between her cheeks. The feeling from it only intensified his bodily changes and sped up the spread of the symbiote on him. As the two symbiotes spread and came into contact, each stopped and new colors spread out over them, signifying their separation. To any scientist, this would have been incredible to witness, but Julian and Jean were so intoxicated by their lust that the moment was immediately overshadowed by the next wave of pleasure. Julian’s shaft continued to grow larger as Jean worked her hips. “Jean, I can’t… it’s too much, I can’t hold baa…” Julian said, failing to get the last bit out before a large load of cum gushed from the tip of his shaft. A satisfied hum was all Julian heard from Jean before she intensified her movements once more. “Don’t worry,” Jean said seductively while cupping her large breasts and looking down at him, “We’re just getting started.”

Page 14:
Julian’s body was buzzing with sexual energy in a way that made him feel like he was always right at the cusp of an orgasm. Each load he released never seemed to satiate his lustful desires, instead only seemed to compound them. With each load of cum he released, a wave of pleasure rushed through him causing his body to change even more. He now had a much more feminine appearance and a large set of breasts that continued to grow with each wave of delights. As he panted and moaned, his voice was now much softer and feminine than before too. His hair had also grown out, nearly matching the length of Jean’s. Jean had moved back from teasing his shaft between her ass and instead started putting her newly acquired long tongue to work. Over and over, she’d wrap it around his now massive shaft working it up and down. Julian’s testicles would swell in size, filling with cum and Jean was there to give them a pleasurable squeeze, helping him to unload. Julian couldn’t help but notice how different his body looked, but he didn’t care. If more pleasure meant more changes, he’d welcome each one. Reaching up, Julian grabbed his new breasts, feeling their weight, which earned a playful laugh from Jean. Both sensitive breasts felt incredibly full and begged to be squeezed. As another wave of pleasure approached its climax, Julian couldn’t help but grab two handfuls of his new breasts, squeezing them together. The feeling took his breath away as his tongue lulled out of his mouth and he moaned. He’s whole body felt as though it paused, right on the edge, he panted harder and harder as he squeezed tighter and Jean licked up his thick shaft, squeezing once more on his testicles. Quivering and shaking with pleasures for what felt like ages, Julian’s body finally released. His new breasts sprayed milk out as he came harder than ever before, feeling as though he was cumming for two. As his feminine moan filled the room, a second could now be clearly heard echoing through his mind, savoring his delights as much as he was.

Symbiote: "I SHALL POSSESS YOU AND TURN YOU INTO A TOTAL SLUT!"
Jean: "Joke's on you, I'm ALREADY a total slut!"

...That cock is just...oh my.

@gamefriend, do you know if there's any rumors as to why everything of theirs got nuked?

Base +6, riderone01 +6, GorbDog67 +6, AWolf343 +6

This reply is super late. It has been a while so I can't recall in exact details, and I think their reply was gone now that they had wiped their contents. Anyway, I realized some of mophingu's posts on Hentai Foundry were gone, so I made a comment to ask about it. Mophingu replied back that making these works had become unsustainable and they wanted to move on. I didn't ask any further, guess that's just life you know

A pity though, I would love to see more symbiote contents from them.
