Nectaria

Excerpt from: Creatures from a New World.
Among the most common looking creatures recently discovered is the Nectaria. Slightly larger than a honeybee, it sports a spotted pattern instead of a striped one. The sting, an alabaster thorn long enough to penetrate the skin, is housed within the thorax, which is wider than that of a common bee. Since it's not attached to any of the Nectaria's organs and doesn't detach, it can be used several times. Still, the poison will only be administered on the first sting.
The poison is the reason this creature, despite looking unassuming and commonplace, is one of the most dangerous found in the New World. It spreads throughout the body in about a week, and after that, it starts taking effect. It causes a fairly rapid, permanent transformation which, depending on whether the poison comes from a male or a female, will have some variations. If not treated properly, it can become permanent, and if not treated at all, it is lethal.
The following is a transcript of what happens when an individual is stung by a Nectaria, taken from Captain Hills's logbook.

Two hours have passed since the previous log, and we seem to have found something resembling honey. A river of it, according to our guide, it's not dangerous to consume. She doesn't seem to be wrong, although perhaps she has developed some sort of immunity to whatever there may be in the honey if it is indeed poisonous. I talked to some of the crew, and they seem to think that taking some of that honey might be a good idea. An'Syl or whatever her name is seems to not be okay with that choice, claiming that it will undoubtedly attract predators to our location. The crew seems convinced, however, one of the researchers wants to take a sample. And our head scientist is gone, her and all the equipment. According to some people, she went uphill, wanting to know where the river of honey begins. Our guide jumped out uphill after I told her what Carline was doing, without a single word. She seemed distressed, so I'm putting the crew together and heading uphill, in case something goes awry and we need to carry either our head scientist or our guide away in a hurry.
Everything seems to be fine. According to Carline, there was a massive hive swarming with a strange sort of bee. The river of honey comes from a massive hive. Makes me wonder how the bees can produce that much honey. While Carline seems giddy with her discovery, An'Syl seems somewhat agitated. I might need to ask her what's wrong later on. On the meantime, that researcher took his sample of honey, which should conclude our business here.
Three days since last log. A strange lizard with feathers attacked us yesterday night. It's tenacious. We are running away from it. Philip is dead. The lizard crushed his head with a bite. An'Syl says it's because of the honey. We'll get rid of it as soon as we lose sight of the lizard.
It's been two days since what the crew has come to call the "Quetzal Lizard" stopped chasing us. We are in no dire situation just yet, but our supplies are dwindling. Furthermore, we are all quite tired from several days of running, yet none of us wants to sleep in fear that the Quetzal Lizard finds us again. After what one of them did to old man Phil, it's understandable. Ankh'Syel also taught me how to properly write her name. And the honey sample is gone, which according to her means we'll sail calm waters again, which is a relief.
Six hours after my last log. Carline's skin seems to be much more pale than usual. I asked her, but she says she's feeling all right. I'll ask Ankh'Syel tomorrow, she may have been bitten by something or eaten something she shouldn't have.
The medic in our crew says it's only fatigue. Ankh'Syel disagrees. She is very distressed, saying that Carline has been cursed for getting too close to the Golden Spring. Does she mean the giant beehive? It's possible that Carline may have been stung by a bee, but it's been almost a week since that. Bee's poison is neither toxic enough nor lasting enough to cause such a reaction on Carline now. It has to have been something else. According to the crew, she drank some honey, but she was not the only one. I'm terribly afraid.
It's been an hour since the last log. I believe this place is getting to me. I need to cool my head, worrying about something that may very well be fatigue doesn't help the expedition.
This is Dr. Wilkins. I fucked up. It's not just fatigue. It's morning, Captain Hills has asked me to take care of Carline while he stays back looking after the camp. Syel and I have been forced to take Carline away from the camp. She thinks Carline's condition, or curse, or whatever, could affect someone else if we don't do so. As of right now, Syel is carrying her on her back. Carline doesn't seem to fully grasp what's going on yet, she's either not fully awake or whatever's happening to her is keeping her woozy. I intend to document her changes, as it could help if any other member of the crew ends up getting the same illness Carline has. As of right now, Carline looks like she normally does. Average height, lithe frame, shoulder-length chestnut hair, peachy skin, green eyes and freckles. Aside from that, C cup breasts, flat belly, wide hips, toned thighs and ass...about 114 Lbs if I recall correctly.
This is three minutes since the last log. Carline's skin has become a dark amber hue. It also looks shinier. Both I and Syel have noticed a sweet smell coming from her. She's kneeling, mouth agape and looking up. Still dozed off. There haven't been more physical changes. According to Syel, her transformation hasn't even started, but it shouldn't take long. I've asked her for a remedy, but it'd seem she doesn't know any. Carline has started to drool honey, according to Syel. Something does seem to be flowing out of her mouth, but I'd rather not check what it may or may not be myself.
This is about a minute after the last log. We were trying to undress Carline at Syel's recommendation. We managed to remove her shirt, shoes, trousers and everything except her undergarments when Syel told me to step away. I can see why. She is swelling quick, quicker than I can write. Her flat belly has turned into a fleshy gut. It ebbs slightly over her crotch, but not to the point to which it'd cover her sex. Her hips, thighs and ass show a clear expansion, straining her panties and nearly covering her calves, which also seem to be swelling. Her breasts look to be in proper D territory now, flowing over the cup. I can see the areola starting to peek out of the bra. She still seems woozy, but now her eyes shine with lust. She is making sounds, although I'm too far away from her to tell what is exactly happening. Her belly is now flowing over her panties, unlike her hips, which are flowing out of them. Walking around her I can properly see how much her ass has grown. Her panties look like a thong from the back, most of the fabric between her buttcheeks, which have grown so far out that they're starting to reach her feet. I can also see that her bra is starting to tear apart, and going to the front I can see her nipple pop out of the cup. I can also see that her labia has swollen vastly. Her undergarments are not covering anything anymore, not even her clit, which is a noticeable bulge in the front of her grey panties. She is moaning softly, and the smell of honey is starting to become overpowering. I can't see Syel. I don't know if she left because she found something useful or because she knows how these transformations can end. Her bra gives up just as I'm stepping away, falling to the floor torn in the back. Her breasts are now looking like proper basketballs. Something is oozing out of her nipple, and if I'm starting to understand this correctly, it's most likely honey. Her belly is now almost covering her sex, which is more visible now than before? I think she's opened her legs. It's possib Her panties have broken as well. I can clearly see a decent amount of honey dropping down from her vagina. Her things and hips are pretty thick at this point. If I had to guess her weight, I'd say she'd be somewhere in the ballpark of 190 Lbs. Her moans are more audible now, and they are starting to make me feel uncomfortable. I can see Syel coming from between the bushes. She's gesturing me to get away, which I'm doing.
It'd seem that her smell will soon become strong enough to start attracting "N'yrena", which I assume are the bees that lived in that giant hive. Carline is starting to resemble a blob, having grown significantly while I wasn't paying attention to her. Now, her once svelte face is cheeky and swollen, and her arms are starting to develop fat, or honey or whatever it is that's filling her, rolls. Her fingers also look stuffed. Her belly is now so big that not only does it fully cover her sex, but it also folds into two. And as I imagined, the "N'yrena", those goddamned bees, are starting to fly around her.  Her breasts are now roughly the size of beachballs, and they are oozing out a consistent stream of honey. And I imagine so is her pussy, judging by the pool of honey now forming between her engorged thighs.
I Ankh'Syel. Doctor vomits. N'yrena burrowing in golden woman's bellybutton. Woman becomes Golden Spring, Ankh'Syel mother too. Golden Spring is strong smell. Golden woman scream, looks happy.
As Ankh'Syel notified, the bees are, or have been, burrowing inside Carline's bellybutton for a while now. She's screaming in pleasure, every scream sending ripples through her fleshy body, which is still growing, but far slower than it was before. I can' properly see her face anymore. Her arms and legs have both been swallowed into the amber mass her body has turned into. Her double-folded belly reaches the floor and still extends several inches forwards. Her breasts are now the same size her entire body was before, her nipples have grown extremely engorged as well. At some point, it'd seem she went from her kneeling position to a standing position, since I can see her legs more clearly now, which are packed with as much flesh as the rest of her body. Her belly does no longer reach the floor, but her sex does, still producing outrageous amounts of honey. Her height must now be roughly twice as she was before. Now her nipples have started to squirt nectar as well as oozing honey. Her face has now risen over her flesh, making her visible again. I cannot even imagine what she must be feeling right now. Probably amounts of pleasure no-one's body was created to withstand. Carline is now completely surrounding by bees, I don't think none of us can do anything for her. Until we can come retrieve her, we have no choice but to leave her here.

It has been discovered that Nectaria bees use the bodies of any transformed creature as a hive, while keeping that creature alive, in a state of perpetual lethargy. When there are no bees around, the body can fill with honey to the point of bursting, however, bees siphon honey regularly, keeping afflicted individuals roughly the same size as Carline was by the end. Being stung by a male results in a transformation mainly focused on the production of honey and nectar. Being stung by a female will create cavities in the flesh in which the Nectaria will lay their eggs.
