Desc: Science Fiction Sex Story: Susan is bored with all porn, even scat porn, until she discovers a new kink - Squirmies: Slimy, fat, genetically engineered worm-like vertebrates that invade the human body for human amusement. She soon becomes hooked, and auditions to become the star of the website's newest video.

I remember when I first heard about Squirmies. Like a lot of people, I was just a bored woman searching for something interesting online. Porn, mostly. But I'd already seen the kinds of things I wanted to, and some of the things I didn't, even scat porn and bestiality porn until I was commenting on camera angles and choices of outfit even in the middle of Hungry Bitches, and while I craved excitement, I was not even remotely interested in anything illegal or vile. No gore for me, no snuff films, none of that nonsense.

After months and months of such boredom, I was finally beginning to give up hope. But one day I saw something new, something that purported to use the latest genetic engineering science to give people something they'd never seen before. The site was called, and so – intrigued – I clicked on it. It looked like a standard porn site, with pictures and a free sample video section. I viewed one of the videos, and was amazed by what I saw.

It began with a beautiful woman, blonde, getting undressed and laying down on an operating table. Once she was settled down, a man came over with something in his hands. I thought it was a snake at first, but it had no head. Some kind of gigantic worm? But no, it didn't look like any natural animal. Yet it didn't look fake or CGI, it looked real. The woman spread her legs, showing her pussy, and the man placed one end of the creature in front of her cootch. It hesitated for a moment, then began to slide itself up her. It was big and long and thick, so the woman reacted favorably to its intrusion.

Once it was up there, it wriggled around inside her, the camera panned to show it distending her belly. A second one was soon put up there, then a third, and the woman looked nine months pregnant with these giant smooth-skinned worm-things squirming inside her. She masturbated while they were up there, but then the video was over.

I was hooked. I immediately got out my credit card and subscribed to the site, and as soon as I could I was watching the rest of the video. She masturbated with the Squirmies as they were called inside her, and then the man came back with a fourth. But instead of putting it in her cunt, another person sprayed her throat with an anti-gag substance, and soon this strange creature was forcing its way down her throat into her stomach. I was masturbating heavily by this time myself, and in a few minutes I had the biggest three orgasms I'd had in a year.

That night, I went to bed thinking about the Squirmies, and imagining them invading my own body; the fantasy was so hot that I brought myself to another orgasm before going to sleep. I had a new kink, and I knew it.

Over the next few months, I watched every video they released, downloaded every picture, and was one of the top posters on the forum. And I fantasized about being a Squirmie girl so much, that I worked hard, did so much research about the Squirmies, until I finally found out what I wanted to know: where to go to audition.

I am lucky enough to be a beautiful woman, though if I'd been born in another era, I wouldn't be so lucky, since I had been born assigned male at birth. But with a combination of nanotechnology and 3D-printed human organs using my own DNA, I was now the proud owner of breasts, a vagina, a uterus, and ovaries; all the working plumbing, so to speak. I am a woman; only a DNA test would ever contradict me, and I was saving up to have a DNA re-sequencing operation. If I got the role I wanted, I could indulge my kink and pay for my operation at the same time.

The audition went well. They liked my looks, my voice, and they were thrilled to find out that Squirmies were my kink. Apparently, they shoot their videos in one take, and prefer people who genuinely like having their bodies invaded.

"So, Susan," the director, a mustachioed man with hazel eyes and dark tan skin said to me, "one more thing: we've gotten permission from the FDA to add something new to our repertoire with these videos, if you're interested in trying it out sometime. You can change your mind at any time, but just sounding out the possibility first."

"Try what?"

He whispered into my ear (I shall not spoil the fun by telling you what he said), and I felt my pussy get wet and tingle. As soon as I could, I said, "Yes, that sounds like something I'd very much like to try," I said.

"Good, good. Now, if you're willing, we could start filming after lunch. And I can discuss a few other things we might try, too."

I grinned. This was going to be a great day.

An hour after lunch, the director led me into the studio. I recognized the table from the videos I'd been watching for months. I felt a little like I already had things squirming around in my belly as I saw it, I was so excited. The cameras started rolling, and at the director's cue, I stripped naked, pulling my long black hair out of its ponytail. I should probably describe myself some more. I am 5'10'', with pale skin and green eyes. My breasts are a C cup, and I'm slender but not Hollywood skinny. I kept my pussy clean-shaven, too.

I climbed up on the table – an old gynecologist's setup – and put my feet on the stirrups. One of the men slathered my belly with a gel filled with nanites designed to make my skin stretch fast without tearing, which would also put the skin back to its previous state after everything was over. I believe it also made the skin more durable, too.

Soon after, I saw it, being carried over by one of the men. It was long, fat, and green, tapered on each end. The man let me touch it first. The director had explained everything over lunch, but I already knew – Squirmies are made from reptile and mammal DNA, and also amphibian and penguin DNA. They can breathe through water, they can hold oxygen in their blood for hours without breathing, and they ate only moss. Also, their poop was sterile and non-toxic, so if they had any accidents inside me, it wasn't going to make me ill. I was not surprised to find its skin was moist, but I was surprised by its warmth. It had no eyes, either, but it seemed almost to be looking at me anyway.

After having touched it, Raul – the Squirmie handler – took it down to where my legs were splayed open, and lay it down by my crotch. I felt my pussy tingle with excitement and anticipation, especially when it nuzzled my cooter a little with its ... nose, for lack of a better term. And then, by whatever programming they had given it, it started sliding inside of me, a warm, moist, crawling sensation better than anything I'd yet imagined. And then its thicker parts started working their way in, and I began making little moans and whimpers of joy as it stretched my cunt on its way in. I played with my nipples as it slid the rest of the way in.

It was truly glorious. I could feel it inside of me, this thing that should not be there, invading my body. And I loved it. I watched it push against my insides, its shape briefly visible against my skin. I wanted to masturbate, but Raul was preparing a second Squirmie, and I didn't want to startle it. The second one went in much faster than the first, as though it had some need to join the other one. This one was a lot thicker, and almost didn't fit. It hurt a little, but not much, and the pleasant tingle its fluids left behind in my cunt more than made up for it.

Now I could feel the both of them inside me, and I could feel every place they touched my insides. I watched with delight as they distended my belly, and I even enjoyed them beginning to push my other organs aside.

Then the third one was inserted, and I felt a lot more discomfort, since I too looked nine months pregnant now, but that discomfort was balanced by how amazing it felt to be invaded like this. The writhing visible in my belly's skin was turning me on so much. I was finally able to start masturbating, so I did so with gusto. But it was difficult, now, to reach down there around my gigantic belly.
