A crash.

I was laying in bed with just a pair of pajama pants on, trying to fall asleep when I heard a crash, or more like a thumping as someone jumped into my lounge room window. I didn't even realise I had left it unlocked but now my danger senses were going off. If I was lucky, it was just a drunk person who I could shoo out, less lucky, someone was here to rob me or worse. I didn't really have much to steal and I didn't want to risk leaving some drunk out in my living room to throw up everywhere or break shit.

I dialed the cops, let them know what was happening and slowly made my way over to the door of my bedroom. I opened it to reveal... nothing. There was no one that I could see in my living room. I only lived in a one bedroom apartment and the bathroom is an ensuite... maybe whoever broke in already let themselves out?

I didn't know whether to be relieved or disappointed that I wasn't worth stealing from as I walked over to my window and front door to double check the locks. That's when I heard footsteps running towards me...

I whipped around as fast as I could just as the Intruder tackled me to the ground, the wind getting knocked out of me as I tried to fight back. He tried to push my legs up but I kicked him off before rolling over and trying make a dash for my bedroom, if I could get in and lock the door I would be safe for a little bit while the police arrived. Unfortunately I was a little too slow and he managed to grab one of my ankles out from under me, tripping me as I crashed into the floor again hard. 

He quickly climbed on top of me, straddling my legs as he pinned me down, I tried to buck him off but he was too heavy as I wildly flailed about with my arms, trying as hard as I could to get away from the Intruder. He grabbed my arms and twisted them behind my back, making me cry out in pain as I felt him tie them together with rope.

After my hands were tied up, I felt him push me flat and lift himself off me but only slightly as he grabbed the sides of my pajamas bottoms and started pulling them off me along with my underwear as I started writhing harder, telling this freak I was going to start screaming and the police would be here soon.

His response was to use my own underwear to gag me, all I could taste was my own ball sweat as I was now lying naked beneath him, dreading what would happen next. I had been with guys before, so if his plan was to rape me, my ass wouldn't be destroyed, as long as he didn't have the worlds largest penis. 

He told me how he wanted to be nice to me but since I fought back, now he was going to be a little rough and so I prepared myself for the worst to begin but instead found myself shivering as something sticky touched my asshole, not like lube sticky, but properly sticky. I turned my head around as far as I could, seeing the Intruder standing above me but at a distance but I couldn't quite see what was touching my butt.

That's when I felt it move and to my horror, whatever was touching my hole was growing, I felt two more little slimy things touched my ass cheeks and pull them apart and when I finally strained my head all the way around, I saw it... a parasite with three tentacle like appendages attaching itself to my ass, two of its tentacles sealing themselves on my cheeks while the third started to dig its way into my hole

The third tentacle was easily the largest as it buried deeper and deeper inside of me, I could feel my hole stretching to accommodate it as the tentacle just got longer and girthier inside of me before finally coming to a stop. Slowly, it pulled back out of me and then picked up its pace, rapidly fucking my asshole as I screamed against my gag. The Intruder just laughed at me as the parasite worked faster and faster, my own cock becoming erect as it pounded into my prostate.

Before long, it buried its tentacle deep within once again and held it there, that's when I felt the tentacle swell up as it started dumping its huge load inside of me, there was so much cum, it felt like an endless stream up my ass as it filled me up to the brim and then kept going, my stomach beginning to bulge as I was inflated by its load. I felt sick as the Intruder walked around me and picked me up, sitting me back on my heels as I looked down at my bulging stomach, the liquid sitting deep with in me as I felt my own cock standing at full mast, not that I could actually see my own cock anymore. 

After filling me up, I felt the parasite swell up once more, this time it deposited eggs inside of me, one at a time I felt them travel through the tentacle before popping out into me, the sensation of the eggs was too much as I reached my own climax, shooting my load all over the floor as I bucked my hips wildly.

The Intruder told me that unfortunately, I had the wrong appendage to be able to properly lay the eggs after they were inseminated by him but not to worry, he would fix that. He produced another parasite, this one more like a slug as he knelt down and took my dick into his hands. I couldn't do anything, I was still tied up, inflated with cum getting eggs deposited into me as he attached the slug-like parasite to the end of my penis.

It wasted no time in quickly slithering down my entire length, consuming my penis in one swift movement before resting there for a moment, it felt quite nice around my cock, the warmth providing a bit of comfort but it didn't last long as it attached itself just above my pubes before retracting itself, except as it grew smaller, it was shrinking my penis with it!

I lost sight of it beneath my huge belly but could still feel it consuming my penis as it reached the base of my cock and kept going, sinking into my skin as it opened up a new kind of genital instead, my penis having been turned into a parasitic vagina. I could feel it merging with the rest of my organs, as I felt some of the liquid the tentacle parasite injected into me leak out.

The Intruder stepped towards me and I looked up for the first time in a while to see him stroking his cock, it wasn't a regular human cock, it had clearly been enhanced by the parasites as it stood as a nasty 14 inches long and it was easily 5 inches thick as well. I feared for my new organ but it did nothing to deter the Intruder as he pushed me onto my back, raising my legs up into a missionary position as my stomach swished around with the movement.

He rubbed his cock against my new organ for a moment and I whimpered in anticipation, I had a feeling he wasn't going to be gentle and I was proven right as in one swift motion, he buried himself hilt deep inside of me. I felt his impressive balls slam into my ass as I screamed in pain into my underwear gag but he didn't stop, pistoning into me with his monster cock, pushing my legs further back to give himself a better angle.

I could feel him slamming deep inside of me as the sensitivity of my pussy caused me to cum again, squeezing his cock hard as it penetrated me, thats when I felt the tentacle slowly retract itself from my asshole. I was so focused on my new pussy, I had completely forgotten about the pain in my asshole as I felt more liquid gush out of me, my stomach deflating ever so slightly as the Intruder pounded me with even more fervor.

It wasn't long until he slammed himself deep inside of me and I felt his warm juice flood my insides as well, mixing in with the eggs and the parasitic liquid as he held himself there for a while. My knees were practically touching my shoulder, that's how bent into a pretzel I was, I had completely given up on freeing myself from my bonds as I waited for him to come down from the high of his climax.

Finally he pulled out of me and cleaned his cock off with my pajamas, tucking it back into his pants as I let my legs relax, putting them back down to the floor as I felt something stirring inside of my stomach. He looked up and began moving my legs again, spreading them out wide while he kept a close eye on my pulsing vagina.

Something began moving inside of me, causing my stomach to shift and bulge around before I felt it find the opening to my pussy, pushing itself out as I birthed another parasite into the world. The Intruder quickly grabbed it and put it into a special case he had, I didn't even notice it until now. This happened about 20 more times, as I birthed parasite after parasite each one pushing out of me and causing my stomach to shrink before finally, I was back to normal size and he grabbed the last parasite, placing it into the case.

Thinking it was over, he called out to the slug parasite and I felt it slime its way out of me but it didn't bring my dick back, instead slinking off of me and leaving me with a vagina, the Intruder told me it was just a side effect of the process and that I would have to enjoy my new life as a mother before laughing and leaving through the window he came in.

I couldn't take it anymore and lost consciousness, still naked on my living room floor...

I could feel myself stirring out of unconsciousness except I wasn't laying on my living room floor anymore, I was bouncing up and down, I cleared my eyes to see a man in a police officer uniform holding me up against my wall, his brutish cock pushing into my vagina as I cried out in my gag from the intrusion, he told me that's what happens when you make emergency calls for weird sex things and that a good little girl like me deserved cock...
