Dan's plan
It had been just over a week since the Intruder first broke into my apartment and raped me, impregnating me with his parasites and the aftermath of my encounter with my Personal Trainer had left me with a retractable alien cock and tail. I was slowly getting accustomed to living with both sets of genitals, my wardrobe slowly getting more effeminate as most clothes no longer fit me when I had the massive alien cock out so I tried to stick with my new vagina as much as possible.
I was slowly running out of clothes, however, and I needed to do washing, I was lucky I was able to work from home so I didn’t have to go out much in the last week but I didn’t have a washing machine and the nearest laundromat was quite a walk away, I grabbed my last shirt and pants I had left, not even realising that it was the pair of yoga pants from last week until I had already pulled them up and felt the sticky wet patch against my pussy.
Suddenly, pangs of hunger and desire flooded my brain, making me fall to my knees as my insides started burning, flaming up with the NEED to breed, or be bred, the parasites causing my ass, pussy, cock, balls, brain, everything to be filled with the heat to produce more parasites.
I began getting flashbacks to the my initial infestation, my swollen belly slowly pushing out dozens of parasites and my body needed MORE. I needed to bring more parasites into this reality, and slowly running my hands over the bump in my yoga pants, I knew just the target for the next generation of parasites…
I walked up to the gym where my Personal Trainer, had teabagged me and throatfucked me last week, I pulled up my yoga pants, making my cameltoe sink deeper and show off my pussy even more, I needed sperm in order to produce parasites so I planned to make him fuck me anyway I could, and then I would turn the tables and infest him, turning him into my own perfect breeding ground.
I walked into the gym, my pussy pulsing with anticipation as I waited near the front desk for his last session with a client to wrap up. I looked in and could see him, thick muscles bulging out of his singlet, his 6’3 frame making the women he was training seem tiny in comparison.
He finished up with his last client and walked her out, smiling and laughing until she was out the door but when he turned around, his smile vanished and before I could react, he pounced on me, wrapping his arms around my waist and picking me up, like I weighed nothing, as he threw me over his shoulder like I was a misbehaving little girl, one hand on my ass was enough to keep my small frame steady.
I was expecting to have to warm up to his advances, like what happened last week but apparently he didn’t appreciate me running out on him and he was about to make it known.
He strutted me into the middle of the room where a bench was waiting, he dropped me down for a moment, taking a seat before pulling me back into him, grabbing me neck and pushing me across his lap, bending me over his knees as my ass hung in the air, presenting itself to him while he held me there, his other hand squeezing and groping my ass.
I started to wiggle my backside to entice him even further but I was cut off with a resounding SMACK across my ass, the pain spreading down to my sensitive pussy as I cried out, his meaty hand leaving a red mark on my ass through the yoga pants. He didn’t stop at one though, his hand reached over to the other side, spanking my right cheek just as hard as he treated me like they used to in Sunday School.
My pussy dripped from the impacts on my ass, the sting from just two of his spanks burning my cheeks, I tried to get accustomed to the pain but before I could brace myself again, two more resounding SPANKS rang out across the gym as my PT started laying into my ass, his giant hands slapping against my yoga pants harder and harder as he spoke dirty words to me, calling me a naughty girl.
I pleaded with him, begged him to stop but he didn’t let up, spanking me faster as we reached 20 spanks on each cheek, my cries of pain getting louder but also mixing in with moans as my vagina was soaking wet, pulsing against his lap, which he took notice of.
He grabbed my yoga pants with both his hands and ripped them apart, exposing my ass, the cool air stinging against the burning, wasting no time in shoving two of his fingers inside of my wet pussy. His thick digits already stretching my tight, sensitive pussy as he resumed spanking me, now there was nothing to protect my bare ass as he slapped my ass with renewed vigor.
Moans joined my cries of pain as he roughly fingerblasted my pussy, scissoring me and curling his fingers inside me, his painful spanks only causing my hips to buck further into his hands as I writhed beneath him, my orgasm building quickly as I felt the parasites inside of me begin to stir.
No, no, no, this wasn’t how it was meant to go, he was meant to try and fuck me, exhausting himself in the process so I could turn him and infest him but if I cum now, I won’t be able to move, I could even pass out, leaving me helpless against him.
I tried hard to resist my building climax, focusing on the pain of the spanks rather than the pleasure of the fingering but he appeared to notice my sudden resistance, so my PT switched up tactics. He slowly drew his rough fingers out of my pussy, giving one more rough spank on the way out as he instead pushed them into my waiting asshole, forcing my asshole to stretch wide around his fingers.
I couldn’t hold back, the sudden intrusion on my backside released the floodgates and I came viciously, screaming as I squeezed my tight ass around his two fingers while they continued to stretch and fuck me. I rode my orgasm to the ninth degree, not even realising that my PT was shifting our position until I felt his thick cock sliding between my cheeks, the juices from my orgasm coating his dick as he rubbed it all across my pussy and ass.
I feebly tried to stop him, attempting to crawl away from his assault but he just grabbed onto my hips and pulled me up into doggy style, his thick shaft returning to my crack as he began lining up his mushroom head with my waiting asshole, and pulling me into him, forcing all 9 inches of his massive cock into me.
I moaned loudly as he slowly pushed his way, feeling every inch of his glorious manhood as it pushed against the walls of my ass, until finally he bottomed out inside of me, his coarse pubes brushing against my asscheeks, stinging them once more from the battering they took earlier.
He wasted no time in drawing his cock back out of me before pushing it back into me, this was a slow fuck, one that showed he was in control as he used my body as his own personal sex toy. He adjusted his hips, causing his cock to sink deeper into me, hitting the perfect spot as I let out a loud moan. Bolstered by his find, he began to pick up speed, pounding into that same spot over and over as I let out moan after moan for him.
Somehow, I could feel myself regaining energy beneath him, the anal pounding I was receiving helped to rejuvenate me as my strength and willpower returned. I was beginning to plan my next move when I felt him grab my shoulders and pull me up as he laid his back down on the bench, forcing me into a reverse cowgirl position as he drilled his cock upwards into me, the new position causing his cock to hit deeper and sweeter inside of me.
I began to bounce on his cock as he held me there, shoving his dick deep inside of me over and over so I squeezed my asshole around him, getting the reaction I wanted as he began to moan and breathe faster, his own orgasm was incoming, the parasites inside of me squirmed as they eagerly awaited his seed.
He let go of one of my hips, using his free hand to smack me more across the ass, the pain making me cry out which is what he needed, burying his cock to the hilt inside of me as he pumped rope after rope into my waiting organs, I could feel my insides start to shift as he pulled out of me, his leftover climax ending up all over my ass and back as he finally let me go, collapsing onto the bench, trying to catch his breath after he just bred me.
Unfortunately for him, I wasn’t going to let him get off that easy as I swung my legs around, sliding off the bench and taking my place, his legs were on either side of the bench so I picked them up, lifting them into the air as he started to notice what I was doing, laughing to himself as he went to roll off the bench, but I had already transformed, my tail whipping around and catching his arms and pulling them above his head.
The look of fear on his face only grew as he witnessed the monster that had sprouted where my pussy used to be, my 12 inch alien cock pulsing a vibrant green as I rubbed it against his presented asshole, he began pleading and begging me to let him go but his words were quickly silenced as I began pushing inside of him, letting his legs fall onto my shoulders as I began fucking him in missionary.
I knew if I gave him my full size, he would likely break and pass out and that wasn’t productive for what I wanted so I slowly teased his hole with my tip, sliding it in and out, slowly inching further and further in with each thrust as I stretched him to accommodate my girth. My tail squeezed tighter around his wrists as I grabbed his cock with my hands, jacking him off while I fucked him.
I remembered how confident he was, a 6’3 personal trainer now getting railed by a 5’8 twink, my tiny frame being absorbed between his legs but I was bigger where it mattered, pushing more of me inside of him as I reached the halfway point of my cock. His own cock had once again reached peak erection as his hips bucked into my hands.
Since he was clearly enjoying it now, I decided to give him exactly what he wanted, as I pulled my dick out of his ass until just the tip remained before SLAMMING it back inside of him, filling him to the brim with my cock as he screamed in pleasure and pain, his legs flying up into the air as he tried to cope with the sudden splitting pain inside of his hole. I stroked his massive cock, wishing I had a parasite that could turn it into a pathetic vagina so I would have the pleasure of breeding him properly but alas, whatever was being created inside of me would have to do.
I could feel his wrists had stopped struggling so as I began thrusting in and out of him, I wrapped my tail around his cock, jacking him off as my own thrusts became faster and faster. Our moans became a chorus as I jerked his cock with my tail, the feeling was amazing and like nothing I had experienced.
I wanted one more thing before I finished, the tip of my tail climbing his shaft and slowly pushing its way into his piss slit, working its way inside of his shaft as I continued to pound him, the sudden sounding pushed him over the edge as he screamed out in pleasure, cum getting shot into my tail, and out of his cock around it. His asshole tightened as I pushed inside of him one last time, feeling my own climax reach its peak as I began to shoot liters of liquid inside of him, my cock pulsing as it pushed its seed into his waiting ass.
I released his dick as I watched his reaction to his stomach growing larger and larger, as I inflated his entire body with my sweet juice, his stomach was now a perfect bulge, covering most of his body as it jiggled around underneath me. I could feel the first egg pushing its way through my cock and so I pushed against him harder, forcing the eggs to flow through me into him, mixing with my spunk as my PT’s infestation was complete.
I withdrew my cock out of his ass, letting his gaping hole close up, some of the cum leaking out of him but most of it was already being consumed by the eggs inside of him. Now all that was left to do was wait for him to transform and give birth to some beautiful parasite babies…
I reached underneath him, using my tail to help me as I lifted him from the bench onto the floor, spreading his legs as the Intruder once did to me, to give the parasites inside of him an easy way to come out but since we were waiting and I still wanted some revenge from last week, so I moved over to his top side where he was closing his eyes and taking deep breaths, probably hoping this was all a bad dream.
I straddled my legs on either side of his head before plonking my ass down, my alien cock and balls landing perfectly on his face as I began to TEABAG him, just like he had done to me last week, except my slimy alien nuts were a lot worse than his were, I rotated my hips around, covering his face in my goo before lifting my nuts up and down, slamming them into his mouth over and over.
His hands reached up to try and pry me off but my weight was too much for him, the heft of my cock and tail giving me the extra support I needed to keep his face trapped beneath me, I jerked my alien cock off on top of him, leaving my nuts inside of his mouth for him to choke on while I pleasured myself some more.
I watched as his belly slowly shrank, the eggs finally devouring all of the juices they could find, it would only be another minute before he was giving birth and I wanted to watch it from the best angle possible. I hopped off his face as he started grimacing in pain, screaming and crying out as I walked around his body to look in between his legs.
The sight that greeted me, however, was something even more horrifying than I thought. His cock was glowing green and growing, larger than mine, larger than the Intruder’s even was, 16, 17, it was easily 18 inches! I watched as his whole body started getting green and purple veins, his muscles growing and hardening as his stomach finally became flat once more, but it kept retracting, turning into a defined set of abs.
I suddenly remembered that when I was first infested, the Intruder had converted my cock into a vagina, and this must’ve been why! If the host has a female organ, it makes him into the perfect birthing machine but if the host has a male organ, it makes him into the perfect breeder, strong and dominating but this was even worse than the Intruder, who just had a monster cock but was otherwise normal-looking, my PT was turning into a behemoth, or something even worse as TWO ARMS sprouted out of his sides, giving him four arms total as he climbed his way up from the floor.
He was now easily over 7 feet tall, his large cock hung between his legs, swinging from side to side as his whole body towered over me, but even more worrying than his new build, was the look on his face.
Pure rage. It must have been what was giving him the extra steroid dose, his uncontrollable anger that had led to him spanking my ass raw was now giving him even more power, and he was directing that rage at me. Without me wanting to do so, my alien cock and tail shrunk back inside me, the parasites clearly as terrified as I was, leaving me standing before my new infested PT as a useless human.
I tried to take off, turning around and running for the door but four pairs of arms wrapped themselves around me, lifting me off the ground….
