DAY 10

The following days brought a radical change in Rose's behaviour. In just a few days, the morning neurotransmitter overdose from the plant and the orgasmic sessions from the doctors had made her so high that she didn't care that she couldn't move free or even feel her limbs. Only careful daily adjustments of her body chemistry by the scientists kept poor junkie Rose marginally sane.



In order to help keeping her anchored to reality, William had placed a body sized mirror next to the pot so she could see herself whenever she wanted. The mirror was a constant reminder of who she was, but also showed the extent of her progressive transformation. The vine that snaked through her small intestine had already filled it halfway, making her look pregnant with a nest of particularly big snakes.

Each morning brought a renewed growth spurt of the tendrils, and she had become somewhat adept at tracing their movements inside her innards. They were already four inches thick and, apart from filling her to the point of bursting, they had sprouted along her innards, painfully spearing her soft tissues and invading other organs. The doctors even showed Rose from time to time something that looked like an x-ray of her body, pointing what was hers and what was the plant's. Day by day there was a bit more plant and a bit less her.

When she looked at her skin, under the few patches that weren't matted with sticky cum, she could see that it was also slowly changing colour, from pure red-headed alabaster to dryad green. It was also becoming slightly see-through and, under a strong light, she could see on her reflection the faint outline of muscles and bones, as well as the ever increasing vines that criss-crossed them.

That particular day, she awoke with the first sunlight rays to find an exciting change in her body. Her nipple buds had grown through the night, and now resembled two fleshy cones emerging from the cum coating. When Mateson arrived to begin the work day, she swallowed the semen that had been macerating inside her mouth all night long and pointed the fact to him.

"I wondered when they would start showing" he said, fondling the extremely sensitive nubs.

As he stroked and rolled her tender rubbery nipples between his fingers, she could feel something like a hard bean inside them. The friction of her sensitive skin rubbing between doc Mateson fingers and the beans was something wonderful by itself and made her orgasm on the spot.

"I see we are feisty today, aren't we Rose?" Mateson joked

"Yes doctor. Hmm, that feels good, don't stop…" she purred "What are those?" she added, eyes closed in post orgasmic bliss.

"That's a surprise!" the deviant doctor said "One that I wouldn't want to spoil"

Mateson presented his white coated fingers to the girl's mouth for her to clean, a task she did with obvious gusto, and went to work.

That day went more or less like the previous nine. Doctors performing experiments and tests, both on her and on other things around the greenhouse, the daily renewal of the cum layer that coated her inside out, various lengthy pissing sessions, and multiple mind shaking orgasms whenever the scientists were on the mood. However, that evening, a new routine was going to be added to her daily schedule.

"How is the tisular exchange rate going William?" asked Mateson looking at a chart on her pad.

"Twenty percent as of yesterday" answered the younger fellow, taking notes behind a giant flower.

"That means elasticity should be around optimal…" mumbled Mateson "better if we start early before the conversion percentage increases".

Rose watched curiously as Mateson dove between her legs, expecting with a smile another session of mind boggling orgasms. However, the scientist had something else in mind.

He began, as he always did, fondling the child's oversexed clit. The hormones and daily stimulation had made a number on the sex organ. Apart from making it grow, a full inch long and proportionally thick, like a body-builder’s one, it had made it perpetually erect, pulsing crimson at the tune of her heartbeat. The hood had grown alongside it, making Mateson cringe at the unsightly view. He made a mental note to correct that oversight later: a clitoris so beautifully large should never be hidden from view.

Rubbing his index finger up and down, Mateson zeroed on his real target, Rose's peehole. As the child panted with pleasure, tongue lolling out and eyes rolled up, he observed with satisfaction the tiny hole puckering open. Seeing a small yellow trickle, he took a side step and watched how the stimulation made the girl pee herself again. When she finished, sighing in satisfaction, Mateson traced the contours of her labia and lubricated his finger in the juices that flowed between them and the stalk. Once thoroughly covered with the clear fluid, he shoved it unceremoniously inside the girl's peehole.

Rose screamed in shock before the unexpected intrusion. A place narrower than a soda straw had stretched to accept the index finger of a grown man in an instant, and the jolt that thundered through her body had surprised the little child. It hadn't really hurt after all, and the new feeling was akin to the one at her ass. She wanted desperately to pee again, but with such a thick appendage blocking the sphincter she couldn't. Mateson began to piston fuck her last virgin hole with his finger and waved William to come.

"Do you see this?" he pointed with his free hand.

"Hot" was the only answer of the assistant before he went to fetch the tall stool in order to practice what had become his favourite pastime with Rose.

Over the past two weeks, little Rose had struggled to accept more and more of the scientist's oversized cocks inside her mouth. Her goal was to be able to deepthroat them, like she could do with training dildos and normal cocks. Learning how to better perform sexually was what she had been doing since birth, and it felt natural for her to keep at it.

Thanks to the changes her body was undergoing, the feat didn't took long. The very same increased elasticity that allowed her innards to expand to the tune of the plant, or for Mateson to be fingerfucking her urethra, had also softened her throat. Just two days ago, Rose had finally felt William's glans break through the cardias and into her stomach.

Both doctors congratulated the little child profusely, telling her how sexy were her plump lips stretched like an "O" around William shaft, or the wonderful shape her throat took while the bulge of his mighty flesh rod stretched it. They even took photographs and videos of the event, and Rose felt cherished and loved while both men showed her the pictures of her cum coated body and called it beautiful.

While training to deepthroat them she also discovered that, although she could still breath like usually, she could also hold her breath indefinitely if she wanted to, at least during the day. Mateson had explained to her that now, her increasingly green skin acted like the leaves of a plant and gave her cells an oxygen surplus.


She didn't understand any of that, but not needing to breathe was a neat superpower for a cocksucker so proud of her skills like her, so she often made use of that ability, massaging both men's cocks with her throat without fear of suffocation. Once she discovered that fact, she also began keeping her mouth and nostrils full of cum for extended periods of time, enjoying the flavour and odour to the fullest without needing to vacate them. Unless it was to talk or suck cock, she would usually keep her lips shut and their semen inside.

In the wake of her training, William had developed a routine that allowed him to skullfuck Rose without needing to move her. He positioned a tall stool behind her and climbed it. The little girl saw him, smiled in anticipation and tilted her head backwards until her throat was flush with her oesophagus, opening her mouth as wide as she could.

The younger scientist wasted no time and, holding her head for leverage, plunged his full erection into the little minx's inviting hole, reaching the stomach in one thrust and feeling his glans slosh around all the cum stored there. He began skullfucking her in earnest and the sight of her tender throat bulging obscenely in the shape of his cock inflamed his passion, driving him into a frenzy.

Meanwhile, Mateson had added another finger to the mix, making poor Rose overwhelmed by the fierce assault from both ends. The doctor's fingers were stimulating her clitty like never before, rubbing the inside of it for the first time, letting her know about its hidden depths.

She felt her clit radiating the familiar pleasure waves from inner surfaces she didn't knew existed. While William's balls smacked rhythmically her nose, it dawned on her that her clit was like her plant, the roots were hidden from the view, buried in soil or flesh. Those roots were now sending her brain signals so strong that threatened to shut it down.

Before she went unconscious from the over-stimulation, Mateson buried his fingers to the hilt with gut wrenching force and pinched her clit with his free hand. Rose screamed her pleasure through her blocked throat, and the vibrations sent William over the edge. His cum overflowed her already filled stomach, burst upwards and shot from Rose's nostrils and the tight space between her lips and his cock.

Now spent, William withdrew his meat spear from her body and climbed down the stool to see what Mateson had done to her peehole. The previously tiny opening was now gaping and pulsing, spraying little streams of piss to the tune of Rose's orgasmic spasms. She slowly came to her senses and snorted the cum that blocked her nostrils, looking at the scientists with a big grin plastered on her white covered face. Bubbles of cum foamed in her mouth as she spoke.

"Can we do that again? Pretty please?"

DAY 20

Faithful to his own mental promise, some days after claiming Rose's urethral virginity, Mateson prepared the girl for a new modification. He had begun the day spraying Rose's face with a particularly large quantity of cum that had seeped into her eyes and painted her vision white. It wasn't a strange occurrence, though, and she was accustomed to the sting of the substance. She was fluttering her eyelashes madly to clear her eyes from the thick liquid that blurred her field of view and wasn't paying attention to what the doctor was saying.

"Can you repeat what you just said?" asked young Rose while her tears finished the job and her vision returned.

"I'm going to circumcise you, Rose" answered Mateson, re-sheathing his cock into his pants.

"Isn't that for boys only?"

"Not only for them. Here, let me show you" he said, bringing closer the mirror so that she could see her cunt hidden under her belly.

"This is your clit" he pointed grabbing the inch long appendage. It looked like a very small penis, the smooth glans peeking under the hood. "And this is the hood" he added, pinching the flap of skin, lifting it slightly from the clitoral shaft.

Rose was giggling with excitement. Even if Mateson acted all doctor-like and professional, he was still groping the most sensitive part of her body. She was so lucky that such good doctors had chosen her as their test subject.

"Pay attention, Rose!" he twisted her clit playfully, sending an electric jolt through her bound body that refocused her.

"The main body of the clitoris is hidden under the hood, the same way as the foreskin covers the glans of the penis" he continued.

"There is no foreskin on your cocks" she noted.

"Exactly, because we have had it removed just like I'm going to do to you. It's more pleasurable that way" he winked at her.

She nodded in acquiescence, winking in return, which glued her right eye shut and made her laugh. Whatever the doctors did was fine with her, so far all the things that she had experienced had felt good. She still had to live with the pain on her overstretched cunny, her belly still cramped awfully and the feeling of constantly being pooping never abandoned her, but she welcomed them now as much as the pleasure itself.

The older scientist brought closer a wheeled metal tray full of sharp looking steel tools and knelt before Rose's vaginal area. It was a straightforward procedure, thanks to the regenerative abilities that her body had acquired, and he wouldn't need William to assist. Mateson called him nonetheless.

When William arrived, he patted Rose's head in encouragement and knelt beside Mateson, taking care of not obstructing the immobile girl point of view. Mateson then took a clamp and a pair of sharp pointed scissors, abandoning any pretence at subtlety by that point. He used the clamp to take hold of the girl's hood and, lifting it as much as possible, switched to the scissors to cut around the perimeter of her clit, as close as the base as he dared.

Rose was enjoying the procedure. The sharp snips alongside her most sensitive part were no more painful than the myriad of pains that plagued her body constantly and she had learned to live with. The chemically forced rewiring of her brain had obliterated whatever little boundaries remained between pain and pleasure and had exacerbated her masochism to the limit, so while Mateson excised her flesh, she even bit her lip to suppress a growing bout of pain induced orgasms.





The small trickle of blood that flowed from the wound wasn't even red anymore, it had become an orange syrupy sap that hardened as soon as exposed to the air and closed the cuts almost as fast as Mateson made them. The result was that the procedure took less than two minutes and left her clit completely exposed for the first time in her life. Once the foreskin was excised, two more carefully aimed slices took care of the suspensory ligaments that anchored the clit to the labia minora.

The freed appendage now resembled a skinned penis, raw red and throbbing madly, so sensitive that even the slightest flow of air stimulated it. Liberating the clit from its sheath and anchors also made it gain half an inch of length, and without being restricted by the protective flesh, its state of erection made it rise proudly.

Mateson couldn't resist the invitation and swallowed the appendage whole, making Rose finally lose control and cum very vocally. While Mateson used his tongue to explore her feminine appendage, William silenced Rose with a french kiss, an activity that the little girl always enjoyed practising.

Poor Rose was in seventh heaven. The tongue of Mateson was exploring the shaft of her freed womanhood leaving no area untouched, while his teeth nibbled her flesh and added painful stabs to the array of sensations her clit was feeding her. She kept moaning into William's mouth, their tongues intertwining in the lewd dance her teachers had shown her.

The trio kept at it until it was clear that her mind and body couldn't cope any more. Both scientists whitewashed her torso and face with a new layer of their essence, carefully keeping the throbbing nub clean so Rose could enjoy it's sight the rest of the day.

Once she regained her voice she admired the results in the mirror. The painfully erect appendage was scalding hot, shiny with spit and vaginal juices and framed by a string of her own mutated blood, coagulated like sap. To her young mind, the ring of amber beads became a tangible proof of the doctors' love for her, a crown worth of a princess. The heat waves that radiated from the mauled organ flowed up to her brain and reinforced her chemically induced love for both scientists.

"It's so beautiful!" she managed to whisper before closing her eyes in a comatose post orgasmic state.

DAY 30

The weeks after the hoodectomy, William carefully implemented his plan to develop Rose's urethral elasticity. The deviant assistant had set her new goal to stretch her urethra until their cocks could penetrate it. What use was having a pretty naked under-aged girl, unwilling to resist your sexual advances, if you couldn't fuck her however you wanted?

Little Rose had become more a nimpho than she had started being, always starved for any kind of stimulation, so she took to this new lesson with renewed enthusiasm. She didn't have the same possibilities as with her mouth, given her state of immobility, but nonetheless, she tried her best to learn how relax her sphincter as much as she could, or how to use it to exert selective pressure to whatever traversed its length.

The scientists for their part procured some different sized sounds and vibrators from another lab and trained her peehole to accept longer and thicker insertions. Little Rose became giddy with excitement every time Mateson or William unveiled a bigger sized toy. The sensations produced by stretching that hole, and the pleasure it elicited as the progressively bigger phallic objects expanded her innards was indescribable.

The little child went ecstatic every time they shoved a vibrator up her urethra, broke through the sphincter and entered her bladder. She rolled up her eyes and her head collapsed backwards as all the nerves around the piss tube and the roots of her clitoris became on fire. She would often ask William to put his fingers inside to check how she had improved at using her muscles to give a massage.

As a result of the intensive training regime, Rose discovered a new pair of interesting things. The first one was that she had become functionally incontinent. The frequency of their fuckings made her urethra unable to return to its original size after each session, so a small trickle of piss always drained down her peehole unless it was plugged somehow.

The second one was that her bladder was stretching like a water balloon, at its maximum length resting somewhere around her navel. She knew that because she once saw the full contour of a flexible vibrator through the skin of her misshapen belly. Her hide was so taut and thin that she sweared she could distinguish the pink colour of the vibrator through the now semi-translucent layers of green flesh.

Her nipples had kept growing thanks to the beans, or whatever they were, inside them, and now they were the size of a pregnant mother's. Half an inch long, the cone shaped flesh mounds were a source of great pleasure to Rose. The friction on the inside of her flesh caused by those things whenever Mateson or William played with them was deliciously nasty, like picking on a scar, and the thought that something was on its way to exiting her body through there filled her with a childlike maternal pride.

That morning, Mateson had brought a pair of thin tweezers with him as he approached Rose. Her daily routine included a variety of measurements, blood sampling, injections and scanning, but that particular tool was new. The novelty factor always interested Rose, so she tried to focus on the doctor even as the latest vibrator plugging her bladder fed her orgasm after orgasm.

"What are those for?" she asked, her voice trembling in barely contained pleasure.

"You will see. You are becoming very impatient for a plant, aren't you?" retorted Mateson.

That was something that the doctors were insisting on a lot, lately. Well, she couldn't move, she was rooted to the soil of her pot, she didn't need to eat or drink, even if she could somehow digest semen, and sunlight made her very happy. Above all she had become green and, even if she still hadn't leaves or flowers, since all the process started her body had undergone so many changes that she believed it was just a matter of time.

Mateson approached her chest and used his trusty water soaked sponge to wipe clean it from the omnipresent dense coating of cum. Then, he placed the tweezers points dead center on her right nipple and began to push. The pore that had appeared when the nipples first started growing had become a veritable small hole, and the tweezers slipped inside once Mateson wormed a bit the metal tool.

Rose couldn't quite describe the sensation that the tweezers were eliciting inside her nipple. It wasn't painful, nor pleasant, but something hovering in-between. Definitely another interesting feeling to add to her ever growing catalogue of aches and pleasures and something to look for in the future. Once he was deep enough, Mateson released his grip on the tweezers, allowing the points to separate and forcing the small opening even wider, making Rose yelp in surprise.

The scientist then looked closer and a smile formed in his face.

"I see it's progressing well" he said, taking a hand mirror from a nearby tray and placing it so Rose could see it too.

"What is that?" she said, angling her head to see better.

Deep inside the hole, the tweezers had exposed something shiny, red and blunt tipped. She couldn't imagine what that red thing that nested inside her breast was, but before she could ask Mateson, the hole filled with a clear golden liquid that pooled into a drop at the very tip of the nipple.

The scientist scooped with his index the small amount of that mysterious liquid and tasted it with a look of satisfaction plastered on his face. Rose was bewildered by what was flowing from her undeveloped flat chest and, when Mateson re-coated his finger with the stuff and presented it to her mouth, she sucked it without thinking.

"Tastes sweet!" she said with admiration, barely remembering the last time something sweet had graced her palate.

"Indeed it is. This fluid will lubricate your nipple when it births that red thing you have seen, and its twin" he said while extracting the tweezers and repeating the operation on her left nipple.

"But what are they? You haven't told me yet" she pouted.

"All in good time. Remember that I promised you I wouldn't spoil the surprise?" he answered, as a fresh dollop formed on her now unblocked teat.

Once both nipples were dripping the golden liquid, Mateson did something that heavily amused little Rose. He latched on her right nipple and began sucking the sweet nectar as if he was a baby drinking milk from his mother. She felt the release of a source of internal pressure she hadn't noticed before, and sighed with satisfaction.

During a blissful moment, Rose felt like a mother feeding his child. She reminded how her own mom had always been available for her children whenever they felt like drinking milk, back in the nursery. Her oversized breasts, almost as big as her children were, always had one child or another latched into the teats, eagerly drinking the sweet white liquid.

Mateson finished draining her right nipple and repeated the operation with the left one. Once he had done both, he dove straight for her lips and kissed passionately the little girl. As their syrup coated tongues coiled and uncoiled in the dance of love, she thought that her new life couldn't be better.

DAY 40

From the day Mateson had unblocked her nipples, that sweet nectar hadn't stopped flowing. The constant trickle formed a pair of sticky paths that run straight to her hips and then dripped into the soil, diluting the perpetual cum coating on their way. From the distance it looked like she was dressed with a white t-shirt decorated with two vertical golden lines.

Every day, Mateson or William took a small sound and scraped the inside of her nipples, unblocking the tubes from the dried syrup that had accumulated during the night. Then, they relieved the girl from the excess liquid with obvious gusto, much to her chagrin at seeing the traditional roles of adult and child reversed.

The range of activities they indulged in was slowly expanding. However, both scientists always managed to find time for their pretty test subject, and playing with her ever growing clit, coating her on a fresh layer of cum or stretching her urethra never was out of their schedule.

Rose was, in fact, savouring the last load that Mateson had deposited inside her mouth when he saw William entering the greenhouse carrying an enormous bag. He closed on her place and with a loud "thud" dropped the bag to the floor, straightening while he massaged his kidneys.

"That bag weighted a ton! I must be getting old" he winked at her.

"What's inside?" she asked candidly.

"Oh, just plain ol' fertilizer for your roots, Rose. Nothing exciting this time, sorry" he apologized.

She was a bit disappointed, but the fun never really ended in the greenhouse and she was sure both of them would come with a surprising new experiment to try on her sooner or later.

William opened the bag and went for some gardening tools. Fortunately, the plant required little maintenance, and most of the nutrients needed soaked the soil regularly through the tubes connected to the pot. However, from time to time, it was necessary to renew the soil and add some substances that could not be delivered through water. It was, in fact, the first time such an operation had been performed, so Rose felt curious about it.

The foul odour of the fertilizer slowly started to fill the greenhouse. It was an earthy smell, deep and acrid, that remembered Rose of the diaper changing time, back at the nursery. That daily activity was so distant that it now seemed to have happened to a different girl. Unexpectedly, the stench stirred her bowels, and reminded her of a need she hadn't experienced since she had been planted there. She was suddenly hungry.

She didn't know what to think. How could that manure smell so appetizing? Fertilizer was food for plants after all, people didn't eat that. Immediately it dawned on her, it was so obvious that she would have slapped her forehead if she had retained the use of her hands. She was not human anymore, as the doctors insisted time after time, she was now a plant. When William returned with his tools and began to work with the dirt of her pot she didn't hesitate asking.

"Can I have some of that?" she said, looking at the opened bag "I'm suddenly very hungry"

William looked at her in a stunned silence for a moment. Then he nodded with his head.

"Sure, sweetheart. Let me finish this and I 'll let you try some"

William wasn't really shocked about Rose asking for fertilizer. He had been surprised that it had happened so soon. That could only meant that the process was more advanced than what Mateson and him had estimated. A good sign and an indicator that the specimen was of prime quality. Of course, her new needs, triggered by the appendage nesting in her stomach, opened a new batch of exciting activities that he had enjoyed very much with past test subjects.

Once he had finished renewing the soil that supported Rose's vegetable symbiont, he used a hoe as a spoon and scooped a small amount of the earthy substance from the bag, presenting it to the child. Rose licked the brown heap and chewed a little bit.

The taste was ten times worse than the smell, it flooded her mouth and nostrils and made her light headed. It was positively awful and stinky, and she liked it. She rolled the small amount through all the corners of her mouth, trying to extract as much flavour as possible from the fertilizer, pretty much the same she did with the wonderful semen.

William had observed her every reaction and, as soon as she swallowed that first sample, he moved the hoe closer to her lips. She opened her mouth wide and devoured all the contents of the gardening tool, a happy expression plastered on her face as she munched on the manure.

It was not perfect though, and she let William know.

"I like it very much, thank you!" she began "It's a shame it crunches so much on my teeth."

"Well, Rose, it's fertilizer after all. It needs to have soil mixed in"

"But it's so unpleasant" she protested, her teeth gritting with the little grains.

"Hmm" he started reflexively "I think the only way to avoid that is going straight to the source, before it has been mixed with dirt" he explained dutifully.

"The source?"

"Yes, you know what I'm talking about Rose, you are very intelligent. Where do fertilizer come from?" he asked.

"From poo?" she said, not very sure.

"Poo! Exactly! Very good, Rose" he congratulated her while stroking her inch long clitoris.

Rose felt very good with herself. Of course it was poo! how silly of her to not have thought about that sooner: the smell told it all.

"But how can I get poo? I haven't done it since I came here"

"Well, you have doctor Mateson and me" he said "I'm sure he will help you as well once I tell him"

"Really? Will you do that for me?" Rose yelled excitedly.

"Of course, darling, how could we refuse our precious plant girl?" he patted her head "In fact, I was going to go to the toilet soon. I have to dump a big one, do you want it instead?"

"Can I? For real?"

"Of course! let me fetch the stool"

He went to her backside to take his trusty stool that served him so well to skullfuck the little lady and secured it on front of her. The same way that his cock was level with her head whenever he climbed it put his asshole at the correct height. He dropped his pants and boxers and climbed the stool, this time presenting his asshole to her mouth instead of his cock.



It took a bit of manoeuvring to position himself correctly but, when he felt the tongue of the vivacious girl probing tentatively his ass, all the discomforts of his forced posture felt more than worth it. He spread his ass cheeks with his hands to give her better access, and saw doctor Mateson looking at them intently.

"Already?" was all he said.

"She is very precocious" William answered, moaning when he felt the tip of her tongue entering his puckered hole. No matter how many girls they experimented on, he never got tired of that.

"I wouldn't want to miss this for anything. Think she will want more once she is finished?"

"I'd bet on it, boss"

The stimulation of her wet, flexible tongue was too much for his sphincters to keep holding their cargo, so he relaxed and felt a big turd sliding down the chute.

Rose was delirious. Once she had taken the first licks, she became entranced by the musky aroma of his fresh shit. She dug into the hole trying to coax the tasty treat hidden inside, so she sucked and tongued and lavished his hole inside out as best as she could. Her efforts were soon rewarded when she felt something hard pushing against her tongue.

The fresh turd began his travel down and Rose opened her mouth as wide as possible to accept it into her waiting maws. When the tip touched her palate the foul flavour flooded all her taste buds and, closing her eyes, she felt how the slimy, thick turd began to slide effortlessly from his ass directly into her. The rope of crap wasn't as thick as their cocks, so she just relaxed her throat and let it flow continuously in an unbroken line straight to her stomach, closing her lips around it to better feel the texture of the log as it passed. Rose didn't dare to chew, she wanted it all and wasn't risking the turd breaking if she closed her mouth.

Mateson lost it when she kissed the turd and saw her throat bulging with its mass while she used her muscles to force its travel downwards. He was openly masturbating in front of the perverse scene, his eyes barely believing the pleasure he saw in the girl's face as she practically inhaled the fecal substance.

William's load was fairly substantial, but he finally finished dumping it and pinched his sphincter close. Rose took this as her cue to close her mouth around the tail of the shit snake and began chewing the morsel. Her teeth broke the soft material easily, aided by her copious salivation, and she enjoyed the bland texture a lot more than the grainy one of the manure. She kept munching the substance until her mouth was full of creamy shit, enjoying how the overwhelming taste and odour soaked her every fibre.

She only stopped when long ropes of cum launched from Mateson's cock landed straight on her face, covering her eyes and blinding her with the stinging bite of the semen. Looking at the older man through a veil of translucent white she smiled and dutifully swallowed the load, feeling how the tendril at her bowels writhed in response to the substance. Her plant symbiont celebrated the influx of nutritive material with a cascade of hormones that filled her brain with a satisfied languor.

"Can you give me some more? I'm still hungry" she said mischievously, her breath smelling like an open sewer.

DAY 50

Having a sweet mouth eager to accept their daily excrements, both scientists discarded the use of toilets altogether to have their assholes lavished by her flexible wet tongue. Rose didn't even object to rinsing her mouth with their piss after every feeding of either cum or shit and soon, whenever they needed to relieve themselves of solid or liquid waste, they reached for the little strumpet.

Now that the plant was receiving additional nutrients daily, its growth accelerated exponentially, changing her body more and more, in overt as well as subtle ways. With her mouth doubling as a toilet, it was not long until Rose felt one of such alterations.

It happened some days after that first session, while she was trying to down a particularly long and thick turd from doctor Mateson. It was so long and consistent that the beginning had firmly lodged itself at the bottom of her oesophagus and the end protruded slightly past her open lips.

Rose was chewing dutifully to try to soften the dark brown mass, while at the same time working her throat muscles, in the same peristaltic motions that both men liked so much when she deepthroated them, to ease the passage of the massive log. The vibrations of the latest toy stuffed in her urethra reverberated through all her body, distracting her from feeling the change at first, but when the turd finally decided to continue sliding towards her stomach she definitely noticed it.

"Doctor, I think my teeth are loose" she said sending a waft of foul fumes towards Mateson.

"Let me take a look then" he answered, having just finished injecting the girl with one of the many substances needed for the experiment.

Being a pervert without limits, Mateson found her new smell quite erotic, and he opened her filthy mouth to take a look at her brown caked teeth. Using his index finger, he prodded here and there, confirming what the girl had just said.

"Indeed, they are loose" he said "I think it's better if we remove them now, lest you swallow one by accident"

"Why are they like that?" Rose asked, unable to resist her tongue from probing one loose tooth after another.

"The calcium of you body is being redirected to other purposes, and their roots are withering away"

She gazed at him with a look of incomprehension, but also complete faith, in his words. The reasons were unimportant to her, all she wanted was reassurance that everything was proceeding as it should.

"Don't worry, it's all according to plan" he calmed her "I'll go fetch the pliers and we will get rid of them right now!" he finished, patting her head and making her flash a smile that soon would be devoid of white.

The tool rack nearby had a pair of pliers suitable for the work. He wouldn't need to take special cautions, or even disinfect the area. Her immune system was pretty much impervious to infection by that point. Mateson could have slashed her skin open and stuff the wounds with shit and nothing would have happened. Her improved regenerative abilities would shut down any bleeding almost immediately and, in less than twelve hours, her gums would be whole again.

Armed with the chosen pliers, Mateson went to the bound girl and commanded her to held her mouth open as wide as possible. He grabbed her upper left incisive and moved the tooth back and forth.

The excruciating process didn't even make the girl flinch. Worse pains plagued all her body all the time, and she had learned to accept them into every fibre of her being. She was the very definition of a perfect masochist, pain and pleasure holding the exact same meaning to her.

Once he felt it was loosened enough, Mateson suddenly tugged downwards with more strength and the tooth left her mouth in a swift and smooth movement. True to his words, the brown stained root was corroded as if it had been dipped in a strong acid.

He left the tooth in a nearby tray and looked at the hole he had made. The orange sap that had replaced the girl's blood was flowing slowly, already hardening around the wound.

Satisfied everything had proceeded so smoothly, he grabbed the pliers again and chose another tooth to continue the operation. After extracting all the loose pieces, Rose's smile had turned into the toothless grin of the older people.

"You have done very well, Rose" he complimented her.

"Zude I haf" she answered in the accent that now would color her every word, making her giggle at the strangeness of it. It would take her a while to acclimate herself to her new voice, but Mateson knew that her young and pliable mind would soon learn to compensate for the difference until it was barely noticeable.

While the scientist used the vibrator to fuck relentlessly her peehole in reward for her bravery, making her cum again and again, she tried to keep her mouth open to see the results in the mirror, exposing the brown cave dotted with orange spots as much as possible, and probing each and every corner with her shitty tongue. Like everything else done to her, she approved of the new style.

DAY 60

The daily deepthroatings went on to become even more pleasurable for both men, as Rose learned to use her bare gums to massage their cocks on their way in and out of her throat. The loss of her teeth had increased slightly the diameter of her mouth, allowing her to more easily accept their penises, making it seem that she breathed in the meat rods rather than swallowing them.

All in all, her mouth and throat had become the perfect sex sleeve, a condom of flesh to wrap around their monstrous dongs, soft and tender through all its length. Just like a second cunt, as the first one was in permanent use.

Her urethra was also well on its way to accept their oversized cocks, although that didn't stop the scientists enjoying it as much as possible. Day by day, the girth and length of the vibrators was increased, forcing the girl's sphincter to the absolute limits of its elasticity.

In fact, the rubber dongs, having reached and surpassed the boundaries of even her improved tissues long ago, were already tearing the urethra, making dozens of small cuts here and there when the flesh gave way under the relentless assault. Her piss tube stung fiercely with the friction of the fuckings and the constant flow of acidic urine, but small wounds like those healed almost instantly, increasing the diameter of the muscle on every iteration.

The consequence was that her peehole was always on fire, and she loved every second of it, as it synchronized wonderfully with the sensations that radiated from her clit whenever she cummed.

As days went by, the vines kept slowly growing inside her. The one at her ass had traversed all the digestive tract and now coiled inside her stomach, poking its walls from time to time and therefore adding the constant need to puke to the constant need to poo. She would usually retch partially digested mouthfuls of runny shit, mixed with a healthy amount of piss, cum and traces of nipple syrup. However, her naked body was so filthy with layers of those very substances that neither her or the scientists bothered cleaning them. She even came to enjoy the taste of the bile mixed into the foul cocktail when it came the wrong way.

Both tendrils had increased their girth as well as their length, and now, little Rose wouldn't have had the least difficulty in passing a baby through both holes without dilating first. The plant had continued to consume her bones for calcium and other micro nutrients, and it had made her hips warp around the thick tendrils. Even her ass cheeks were now doughnut shaped, wrapping around the woody invader.

That particular day, doc Mateson had busied himself thoroughly examining her arms and legs. The lack of use and the invasion of the ever growing tendrils had painlessly consumed the muscle and bone, and now they were just withered husks, ghosts of their former shape.

"They will never be able to move again Rose, I fear" he explained "although this was an expected result of the experiment"

"Well, if I have grown accustomed to not feeling or seeing them, I don't see any difference in having or not having them" she nonchalantly said, her toothless accent barely noticeable by that day.

"Do you want me to remove them?" he asked.

"Why not? I can't even see my legs because of my belly" she said, looking lovely at her bizarrely pregnant belly and the dildo that merrily vibrated the length of her bladder, slowly suffusing her body in an orgasmic haze that would have turned an unaltered woman's mind into mush.

"Al right then, I will remove them asap" Mateson said cheerfully "William, prepare the saws and the rest of the surgical equipment. Do you want anaesthesia, darling?" he asked, turning again at her.

"Why?"

"Your limbs are already dead for all that is worth, but maybe you don't want to see the actual operation"

"Then no, I'm having too much fun right now to go to sleep!" she flashed a toothless grin at Mateson.

While the mad scientist wondered at how her mind had changed so much in such a short period of time, he and William prepared the tools for the operation that would render Rose into a living torso. It wasn't a difficult operation, given their state of colonization, it was more like cutting the limbs of a tree than the limbs of a human.



Rose watched with curiosity the development, fluttering her eyelashes madly to remove a drop of semen that threatened to obstruct her vision. Mateson and William tied her braided hair in a top bun and cleaned the caked layers of cum and shit around the hips and shoulders, just to see what they were doing, not because they needed sterility. They would begin with her left arm, and the curious child turned her head as much as she could so as to not miss any of the action.

Using a small electric circular saw, Mateson began making deeper and deeper cuts around her left arm, as close to the shoulder as possible. No blood flowed from the cuts while Rose saw her limb slowly detach from her body, just the thick amber sap that she first saw when her clitoris was circumcised.

It wasn't painful, as doc had said, but she still somehow felt the cold unyielding steel of the saw penetrating deeper and deeper into her arm. The inside wasn't just red muscle and white bone as she could have expected, it included a tangled mass of hardened root-like tendrils that intertwined between her human parts and oozed that already hardening sap.

When the scientists were almost done, William took a paring knife and peeled a circular patch from the skin that was still attached to her body and, as Mateson dislodged the rest of the arm with a slight crunching sound, he used that skin flap to cover the circular wound that marked the place where her arm had been. The sticky sap clung to the flap and kept it in place, sealing the borders and making it seem like she had never had that limb to begin with.

Rose felt immediately lighter, as one of the bounds that had kept her in that forced position had been removed, and congratulated herself on allowing the doctors to detach her useless limbs. She could hardly wait for the remaining appendages to be cut.

The operations went as smoothly as they expected. In less than an hour, Rose had been relieved of her old motor appendages and was now supported just by the incredibly thick tendrils that distorted her hips and ass so much. She was standing straight for the first time since she had arrived at the greenhouse, and she enjoyed the sensation.

Doc Mateson displayed her arms and legs atop a tray in front of her. She thought that she should be feeling something when seeing body parts that not an hour ago still belonged to her, but the almost woody appendages that resembled human limbs did not feel like hers, and she didn't experience regret or remorse over having lost them.

"Now you are truly your namesake" said Mateson with finality.
