Months ago, a couple of scientists decided to try and tackle the issue of world hunger. Everyone knows humans need food to live. Everyone also knows that most plants use photosynthesis to create their own food using sunlight. And everyone is well aware of genetically modified plants, even introducing the DNA of certain animals into plants to give them greater resistance to given situations. They can't just uproot and relocate themselves, obviously, that's just silly. But it did get the scientists to thinking if they could do it the other way around - introduce plant characteristics into animals, and eventually humans.
The idea was to allow human cells to house a bit of chlorophyll that would subtly feed the person while in the sunlight, but hopefully not so much the person's skin turns a leafy green. On paper, it sounded brilliant, but tests would be needed to see if it's possible. In practice though, something somehow went awry, creating what seemed to be a successful cell carrying the properties of both a human and plant, but the cell began dividing like crazy before any further tests could be done on it. By the time the scientists began to realize something was wrong, the cells had already begun to specialize into familiar structures of a brain, heart, and numerous others. "Well shit. We've accidentally created life!" one of the scientists said in frustration.
Rather than sterilize the experiment, as was proper procedure, the scientists allowed this rapidly growing... thing to continue to develop, keeping it well watered and nourished, though the latter proved to be about as hard as keeping a normal plant in the light. Within days, their creation had taken on the recognizable form of a fetus... albeit green, and could watch it develop right before their eyes. By the end of the month it had developed into a form resembling a baby girl, and was given the name Flora.
A week later, Flora had developed into what resembled a 5 year old child with flowing cherry blossom pink hair. One of the scientists approached her in an attempt to cut her open and learn about her anatomy... but the positively frightened look in her eyes broke his will to carry out the act. Shockingly, Flora demonstrated a learning pace that was as fast as her development, learning words and how to communicate almost as quickly as the new information could be presented to her.
During all this time, the scientists were trying to replicate the previous result, but without any success. Could one or more of the materials used in Flora's creation have been contaminated with an unknown substance? Or perhaps a freak genetic quirk that allowed this to happen? Either way, it seems to this day that the answers may have been lost when Flora first started developing.
Some time later, the people providing the funding for the project came by to see if it was going anywhere. They were... less than enthused to find out progress had stalled. But then Flora stumbled in, thankfully remembering to cover herself up with her leaves, forming what looks like a two-piece swimsuit patterned after autumn leaves. Investors were both infuriated and frightened of her. Yet even as she stood almost as tall as some of them despite still looking roughly 11, none of them could bring themselves to hurt the plant girl. Funding for the project however was put to an end. "Sorry..." she apologized.
By the end of the second month, Flora appeared to have finished developing. Despite her green skin and intimidating height of 7'10", her... bountiful breasts and almost as impressive ass along with her gorgeous face and smile could win just about any man over. In her curiosity of humans, she's thoroughly studied the subject of sexual intercourse, yet still to this day doesn't understand why humans are so obsessed with it.
In the present, Flora sighs. She knows those that invested in the project that unintentionally created her still fear her, and this fear saddens her. "I'm the only one of my kind. I'm not sure how I'm supposed to procreate, and even if I did I would be teaching my children to respect and help humans, not replace them." she says to herself and lets out another sigh, "There are times I wish my creators were able to recreate another like me... I might not feel so lonely then."
Of course, she couldn't necessarily blame them for being scared of her. The events of last month are still fresh in her mind. Flora had stayed out too long in the sun then, which caused her to grow in large spurts. And with the feeling of her body growing being as intoxicating as it is, it was hard to keep from pleasuring herself just like human females when aroused and get out of the sun to let her body gradually shrink back down to normal. It's a curious trait she has, and her creators couldn't tell her where it came from. She was over 100 feet tall by the time she managed to get out of the sun, but thankfully she returned to her normal size by nightfall where it's safer and she was able to apologize and help clean up.
The annoying part is while it's clear she has a similar digestive system to a human, she still needs some sunlight to nourish herself, and hates the idea of staying cooped up indoors. The pleasure is frustrating to circumvent, and there's also the fear of growing too big to avoid direct sunlight. She can only hope there's some sort of cap on how big she can get, and that she doesn't have to find out how big that is...
"Hey, Flora. God I still have trouble getting over the fact you've got bigger boobs than me..." a voice says, and Flora lifts her head to see Audrey, a pretty young woman who runs a local flower shop. She was the first person outside the scientists who created her to show no fear towards her, thus became fast friends. Flora even comes by sometimes to help tend to the plants, something she always looks forward to. Audrey believes Flora is gifted with a deeper connection to and understanding of nature than any human could hope to achieve. The fact that the flowers Flora has cared for even once grow bigger and more brilliant than the others might give merit to this belief.
"Yes, humans seem to have a very odd obsession over the size of a female's breasts and a male's cock. Like this story of an anthropomorphic horse with such generous curves it's a wonder she doesn't snap in half let alone stand and move about. I've been studying it for months and still don't understand the obsession." Flora replies, "Though I still believe yours are quite nice."
Audrey just smiles and the two friends stand and embrace, Flora lifting the young woman up clear off the ground and setting her down shortly afterwards. "So what are you up to? Not still dwelling on that accident a month ago, I hope." Audrey asks.
"Not much. Just thinking over the story of my life and wondering what it'd be like if I wasn't the only one of my kind. At least I have my friends, right, Audrey?"
"Damn straight you do, Flora!" Audrey replies happily, "Well if you've still got time before you reach the level of sun intake where you start to grow, how about caring for some flowers at the shop?"
