Happy Symbiote (alien breeder)

The others laugh at me, call me 'swamp slut' and 'bug-fucker', but I don't care. I have discovered a pleasure so overwhelming that after each encounter I lay exhausted and happy in the swamp, part of my belly hanging out of me. I'm being used there in the swamp, but I love that use; being taken and impaled so deep until my orgasm explodes over and over.

I don't eat human food anymore. I don't need it. The outpost's doctor tells me I'm now a symbiote for alien life on this planet. The planet where we were sent to populate. Except for the doctor and the pilots, we are all in our late teens and dropped here to breed and grow the human colony on this Class-M world. We were chosen because we are young and fertile, tasked to breed as long as our bodies are able. There is one boy for every three girls, so sex for boys is constant and the girls are happy when new life blossoms in their bellies.

I too am a breeder. Just not for humans.

I know my body stinks of the swamp and alien semen, and sometimes I feel shame for that stink for I have no friends and sleep alone in a pod built for four. But now as I walk out of the settlement onto the path to the swamp, I'm defiant as a group follows and calls out insults and laughs at their wittiness. I am their entertainment, and I must admit that being watched when I'm being bred is a thrill. It makes me feel dirty in a sexy way and I enjoy the curious and aroused expressions on some of the girls' faces. I know they envy my pleasure.

Two of the girls following have firm round bellies, pregnant from the orgies with the other teens. I can see their tits have grown along with their bellies just as mine have. As a symbiote my body reacts to being bred as any other girl's would, and I feel a maternal craving as my arousal draws me back to the swamp to satiate that aching need. And I wonder if the cheeks of those girls' bums are slick as they walk like mine are; so horny and so hungry for what awaits me.

My special place is the crash site deep in the swamp where we lost a pilot on a survey flight. It was while I explored it alone that I discovered the scorpions. They live and breed in the swamp, seeking any living creature to impregnate. Most don't survive, but I do. I have returned many times to feel the ecstasy of symbiotic pregnancy and explosive birth.

I live for it.

The group following stop as I pick my way through the swamp's warm water and lay down in front of the crashed shuttle. They laugh and call insults as I peel off my pants and open my jacket, baring my body. They laugh harder as I spread my thighs and pee into the brackish water.

This is how I call my creature; hormones in my pee acting like a beacon in the stinking water; hormones that tell him a willing female has come to be bred.

Soon I hear the gentle sounds of moving water as my scorpion rises from the murk to loom over me. I spread my thighs wider then, curling my hips and holding myself perfectly still so he can prepare me. The first time I thought he was going to kill me, but I know better now. His tail raises high and slams down into my mound, piercing it to the bone, injecting me with his venom. I grunt from the impact into my tender flesh then moan as the venom spreads over my crotch, my vagina and anus growing loose, the familiar hunger in my belly growing stronger. I want him to fuck me and fill me with his eggs and semen.

As he climbs over me I reach down and cup my vagina protectively and curl my hips, sliding my open legs between his. His ovipositioner slides wetly between my cheeks, then through my relaxed bumhole and into my rectum. I moan louder then, lifting one hand to grip his upper shell and the other to fondle my own tit as his long curved hardness slides deep into my bowels, its hard ridges rippling my bumhole; a promise of pleasure to come.

My descending colon no longer lives on the left side of my belly where it's supposed to; his repeated fucking has pulled it to the centre of my abdomen so I sport a permanent pot belly even when I'm empty. I'm proud of my pot belly that proclaims me as his broodmare.

I remember the first time he moved it; I felt the thin membranes that held it in place ripping and tattering. It was painless and so perversely erotic knowing he was rearranging the architecture of my belly to suit his needs. After the fourth time with him my descending colon stayed in the centre of my core where he put it.

And oh god, how good this feels; skewered by his long ovipositioner as he begins to fuck me from bumhole up to my stomach with each slow thrust. Gushes of his thick semen begin to flow, carrying hundreds of little eggs to bloat my bowels and make my belly tighten.

I am moaning as a slow gentle orgasm begins to pulse in my core with each slow thrust of his rigid ovipositor. The ridges making the special lump in my pussy throb as his semen and eggs gurgle and burble following the ropes of my intestines, making my belly tighter and tighter.

I tilt my head back to look at the boys and girls who continue to laugh as they watch me get fucked and filled. They have no idea how all-consuming this slow, deep fuck really is. How much pleasure I'm feeling as he churns the eggs swimming through his semen inside my belly, knowing that this is just the prelude to an explosive orgasm once the eggs inside me are fertilized and ready to be released into the swamp.

This is the symbiotic part; the scorpions need mammalian flesh to act as a living incubator; the heat inside my belly allows the eggs to open and swallow the sperm. And for me, his semen sustains me, being rich in nutrients that feed my body, allowing me to last three days without eating as the residual semen slowly works its way through my alimentary canal to leave greasy skid marks inside my pants and on my bedsheets. It's why I stink of swamp and semen and why, as it drains from my body, I am compelled to return and repeat this over and over.

I am branded by him; my mound hairless and knotted with scar tissue from his preparatory stings and my tits swollen with milk that no child will ever suck from my body. But by craning my neck I can suck my tits empty as I masturbate in my cot to relieve the powerful sexual cravings I feel all the time.

My belly is aching now, so bloated with eggs and semen, and still he adds to it and churns it by fucking my core from my quivering bumhole to just under my sternum. These girls who laugh at me will never experience a fuck this deep nor an orgasm as powerful as the one that's coming.

In the colony, one girl who likes other girls came to my pod and asked me to show her, so I let her use her fist and arm in me and it felt good as she pushed it up my bumhole almost to her shoulder and she made me cum by flicking my clit with the fingers of her other hand. She enjoyed making lumps in my belly by curling her fist and arm inside me.

When we switched, she tried so hard, but she couldn't take my fist and arm even to the elbow. I told her how to call the scorpions by peeing in the swamp to feel what I feel. She's still working up the courage to do it and I hope she does; maybe we can become symbiote sisters getting fucked side by side and holding hands.

I hear and feel gurgling high in my belly as my swollen bowels force the eggs and semen past my pyloric sphincter into my stomach. It starts to bloat now as well, and I can taste him in the back of my throat.

As my belly aches and my stomach fills, I feel my expulsion orgasm building in my core. He keeps fucking me but now is just squirting semen in me now. I can tell because his gushing ovipositor isn't vibrating with eggs. This pure semen will remain inside me to feed me after I expel the fertilized eggs. Feed me and keep me horny.

God help me, I'm horny all the time. I couldn't stop this if I wanted to.

Girls in the group watching me are transfixed. The two pregnant ones are stroking their round bellies, their erect nipples tenting the fabric of their tops. I know they are imagining what I am feeling, and I wish they knew. because if they did they'd never fuck another boy again.

I feel the pressure inside my belly build alarmingly as my pussy clenches and the scorpion keeps fucking me slow and deep. This is it. This is the moment before an orgasmic storm explodes inside me. I crane my head back so my throat is inline with his plunging ovipositor, preparing to birth his fertilized eggs.

I feel semen and lumpy eggs rising up my gullet.

I feel my bumhole opening wider around his curved rigid shaft and cum starts leaking out of me past its ridges. I take a deep breath.

Then it hits.

As always, It hits hard.

My orgasm bursts inside my bloated belly as eggs and semen rocket up my gullet to spew from my open mouth as my bumhole prolapses, my rectum and descending colon unravelling still wrapped around his thrusting hardness. I am emptying myself in a series of exquisite tight convulsions, regurgitating eggs and semen up my gullet into the swamp. As always, my orgasm is total and all consuming. My toes curling, my hand squeezing my tit so hard it spurts milk against my palm, my mind lost in the maelstrom of ecstasy.

I've seen boys cum, pulsing their milky cum from their quivering cocks as they lose control and I wonder if this is what they feel; releasing their cum in rolling convulsions of ecstasy. I feel like my entire body is a cock, ejaculating my orgasm up my gullet, spewing fresh life into the womb of the swamp.

I can't stop doing this if I tried, my belly in spasms of tight orgasm as my stomach convulses in ecstatic regurgitation, and in this moment of all-consuming sexual euphoria my thoughts turn to dying like the other mammals the scorpions use as broodmares; for when I die I hope it will be at this moment; ending my life as my body heaves and twists as a tight rolling orgasm grips my belly over and over.

But I don't die this time.

I lay limp as the group hoots and laughs at my perverse display before walking away. The scorpion lifts and moves off me, his rigid ovipositor pulling more of my descending colon out of my belly to flop like a drained hose between my limp, quivering thighs as he withdraws. I enjoy these moments; catching my breath, calming as my orgasm still flutters in my belly, aware of the semen still inside me feeling heavy and luxurious, knowing I will have to push my colon and rectum back inside my bumhole and resting until it contracts enough so I can walk without it sliding back out.

I'm a symbiote. A happy symbiote.
