My neighbour catches me

I woke up after having passed out briefly on the floor of the gym, the events that had happened minutes prior still fresh in my head. Not wanting to engage with my new demon PT any further, I hurried out the door and made it all the way back to my apartment building. I passed by one of my neighbours who catcalled me and asked me if I wanted to hang while grabbing his bulge.

I ignored him and pressed forward, determined to make it safely to my apartment which I did, locking the door behind me and flopping onto my bed, falling asleep once more.

While I slept, my body underwent a few rapid changes…


I woke up to a throbbing in my core, my hips bucking themselves upwards over and over as I rolled out of bed, it felt like there was something in me, constantly pushing against my pussy, milking it from within. These damn parasites were causing me so much grief in my new life, I had to find a way to uninfest myself before I become doomed to live like this forever.

As I stood up, something seemed different about the room around me, I couldn’t quite tell until I looked in the mirror and saw myself for the first time since last night. I had shrunk at least 5 inches, making me around 5’1 or 5’2 now and my limbs had also shrunk significantly, making me even thinner and lighter. My facial features had softened as well but my ass had only grown even bigger, I was more feminine than I had ever been and now with my reduced height and weight, it would make it even easier for men to overpower me.

I spread my legs in front of the mirror, watching as my vagina continuously pulsed itself, begging to be fucked by the nearest cock. I put those thoughts away, and grabbed some clothes, although the only pants that fit me were skin-tight yoga pants. I went into the kitchen to try and feed myself but discovered that it was mostly empty and the milk I had was off. Amongst all the chaos of my recent life, I had completely forgotten to go shopping. 

I braced myself as I prepared to leave the house once more, on a quest for food…


I wouldn’t get very far though, as I entered the corridor, my neighbour was once again present, this time with an even more demeaning attitude. He complimented me, saying how I looked different and asking me what I did. I tried to ignore him again and walk past him but I was stopped by a vicious SPANK on my ass.

My ass jiggled roughly as the parasite milking my pussy only sucked even harder at the response to the stimulus. My neighbour whooped at me, saying my ass was even more fun to play with then he thought it would be. He grabbed me and pushed me up against the wall, my ass facing him as he spanked it again, the yoga pants providing me no protection to his rough smacks.

He roughly groped each cheek before spanking them, making good use of his time dominating me as I tried to push off the wall but my weak muscles had nothing good to provide me. His spanks increased in frequency as I began to moan, the parasite inside me turning the pain into intense pleasure.

I only hoped he didn’t turn me around as my pussy juices were flooding out of me, drenching the front of my yoga pants, but he seemed infatuated with my bouncy ass for now as he repeated my punishment over and over.

He rained down spank after spank on me, causing my ass to start stinging as he giggled at my misfortune. One big hard spank was my undoing, as my knees buckled and I moaned loudly, giving away my enjoyment to my attacker. He laughed even harder at me, called me a little bitch for enjoying this so much and spun me around, revealing my drenched front to him.

He gasped in delight, his hand gripping my pussy roughly through my pants as he practically threw himself against me to keep me trapped in my current situation. I desperately asked him to please let me leave and go shopping. He appeared to stop for a moment, considering what I had said but his response was less than favourable for me.

He reached both of his hands down to my yoga pants, gripping them tightly as he tore them from my body, exposing first my pussy and then turning me around and ripping my ass open too, leaving both my holes open for easy access. He spanked my bare ass a couple more times as he asked how I would go shopping now before he picked me up easily, throwing me over his shoulder as he continued to spank my butt, walking us into his apartment.

I looked around to see if there was anything I could use to escape this maniac but unfortunately, he quickly threw me down onto the couch in his living room, lifting one of my legs up and throwing it over his shoulder. He pinned my other leg down by sitting on it and fished his cock out from his pants, I couldn’t see it but as he slid it inside of me, I could feel its massive girth open up my pussy.

As he bottomed out inside of me, I felt the parasite that had been milking me latch onto his penis instead and begin milking it my neighbours cock inside of me, causing both of us great pleasure. He moaned and cursed loudly as he wondered out loud how I wasn’t constantly getting fucked with how good my pussy is.

He began to thrust in and out of me, his nuts slapping wildly against me as he stretched my leg even further, leaning into me to get a better angle on my vagina, our moans began synchronising as I lost myself in pleasure. His hands found their way back to my ass, roughly groping it and spanking it while he continued to pound relentlessly into me.

I heard the door open and my hope rose for a moment that someone had come to save me, but it was diminished moments later as my neighbour greeted his roommate like nothing weird was going on. I looked up at his goliath roommate, the biggest man I had ever seen as they held a conversation like I wasn’t getting pummeled beneath them.

His roommate took his MONSTER cock out and began stroking it, asking if he could join in to my dismay as my neighbour agreed, sliding my leg of his shoulder as he once again picked me up like I was nothing, not letting his cock fall out of me as he wrapped my legs around him, spreading my ass to his roommate before his roommate SHOVED it inside of me, impaling me between the two of them as they both began to roughly thrust inside of me.

Bouncing between them as they traded thrusts, my eyes rolled into the back of my head as my orgasm began building rapidly, the parasite inside of me still milking both me and my neighbours cock while my roommate stretched my ass open wide, not nearly as wide as my monster PT but I worried that if I infested the two of them, what would happen?

I pleaded with them not to finish inside of me but this only spurred them on harder as they drilled into me, until I finally burst out of my orgasm, clenching around the two cocks inside of me, causing my neighbour to also reach his tipping point and bursting inside of me, the parasite inside of me milking every last drop from his cock, my smaller frame making me engorged stomach even more obvious.

My neighbour stayed buried inside of me while his roommate continued to pound my ass, clearly enjoying getting his cock milked. He stayed inside me long enough for the parasite within me to finish consuming his cum and give birth to two more parasites, I cried out as I felt them push their ways out of me and into both my neighbour and his roommate.

Giving birth to parasites while getting fucked was a new experience for me and one I will hopefully never relive as I watched my neighbours eyes light up, his cock slipping out of me. I couldn’t tell what had happened, as far as I could see, there were no physical changes but soon I couldn’t see anything as his roommate slammed me down onto the couch face first, fucking me doggy style as he put one of his legs on my head to help bury himself deeper and deeper into my ass.

I heard my neighbours briefly, describing how he never realised how sexy his roommate was before I heard a loud scream as I felt his roommate being pressed further into me. I was roughly thrown from the couch, the cock slipping out of me as I saw a magnificent sight, my neighbour had buried his cock into his roommate ass and was furiously going at it, fucking him at a speed I didn’t know was possible, causing great agony to his roommate but my neighbour was revelling in the pleasure.

His roommate couldn’t hold back as he began shooting ropes all over the room, spreading his seed everywhere as my neighbour continued to fuck him, except after he had finished orgasming, the roommate angrily threw the neighbour off him and held my neighbour down until shoved his own monster cock inside of him.

They continued to wrestle and fuck each other as I booked it out of their, thankful for the first time to the parasite inside of me…
