I awoke to a mess. There was cum everywhere. Literally—I had to wipe it from my eyelids, and that wasn’t easy because my hands were so caked and soaked in all of it.
As soon as I tried to move, I stopped and looked down at my belly. It was humongous! There were veins and stretch marks everywhere on it. For some reason though it seemed to be smaller than when I passed out. As I tried to sit up on my elbows, I also noticed that I was still impaled on over a foot of my friend’s cock. It felt like I had an arm up my ass and it was warm and pulsating. Was it still cumming!? With post-nut clarity still prominent, though quickly subsiding, I knew I needed to get off his dick so that I could think straight, or else I’d start something that may end up killing me.
I slowly and pleasurably got off of his dick, and once I did the flood gates came crashing. Gallons of cum racked itself onto the floor.
“Damn, I really did a number on you…”
I looked over to see Frank finally waking up. The stimulation must have stirred him. I had to look away because his glorious body was already trying to distract me. His now ten-pack abs and his longer and more built body in general were a Greek sculptor’s dream, an eighth wonder of the world. My cock was already stirring, and I didn’t need another session without cleaning up, washing up, and getting food.
“Yeah, you did,” I said, as my stomach rumbled and more cum flooded out my cumhole.
“That was fucking amazing, TJ. Ima need that ass again.”
Frank was still horny as fuck and hadn’t fully come down from the ecstasy that was his cock and body, so he was still insensible to the fact that anything had changed. He just knew he’d had the most amazing sex of his life and he wanted more of it. Thank God I got up or he prolly would have fucked more cum into me. My cum-belly had definitely deflated some, but it was still looking like I was seven months pregnant. Ignoring him, I quickly waddled to the bathroom and turned the shower on. I slowly stepped in and contemplated our next steps.
There was a lot of testing to be done, but how was the issue at hand. I didn’t want him to suspect anything until I knew the serum was 100% safe. I didn’t want to burn out his life force. Maybe taking a cum sample would be good, but I may need a blood sample. Feeling the water cascade down on my body was so intoxicating I nearly passed out, lost in thought. It appeared that I was more exhausted than I thought I was.
“Whoa, you okay... ?”
Startled out of my reverie, I looked over my shoulder. It was Frank. His dick had gone down to half mast, and though his face still had pleasure and euphoria written all over it, there was a look in his eyes of confusion and concern.
“Yeah, I’m good. I’m just trying to shower up and just lost balance a little bit, but I’m good.”
He looked down at me and his body and as if for the first time it looked like he finally realized something was off and wasn’t normal. As he looked down in awe and fear, I covered my tracks by speaking first.
“So … you wanna tell me why and or how you became like this? I mean, I’m not necessarily complaining, but you basically mauled me like a bear last night. I saw you grow and—”
“I honestly don’t know! I was so drunk last night I literally have no recollection of even getting home. The only thing I remember was waking up on the couch feeling this unbearable heat and desire. I’ve never in my life been that horny. It was like I hadn’t had sex in more than a decade and it all came at once. I lost it at that point.”
I put on my best concerned look and caressed his face looking into his eyes. It wasn’t all an act. Again, I was truly worried, but my cock was clouding my judgement.
“Are you okay, though? Do you feel bad at all?”
He smiled then and grabbed my waist pressing us together. “Nah I’m fine. In fact, I feel better than I have in years. For some reason I think I have you to thank for that.”
My blood ran cold but he couldn’t see my face as I hid under his chin by his collarbone. “Oh, so fucking the absolute shit outta me was your plan all along huh?” We laughed and he playfully punched my shoulder.
“You know that’s not true. I am, or I guess you can say was, as straight as they come. Last night was a first for me, but I can tell you right now it won’t be my last.” He started playing with my abused and very sensitive cunt-hole he demolished only hours ago.
I didn’t mean to, but an involuntary moan came out of my mouth as he fingered me. I felt his monster stir under us and I did not want to do anything without eating and properly cleaning up. I had pretty much washed up before he came in to save me from falling, so I quickly moved under the water and rinsed off. Even though I’d moved away I could still feel his dick slowly rising, it was so thick and girthy swaying back and forth slightly as it pulsed bigger and stronger to its fully erect state. I knew by the look in Frank’s eyes that his sanity was receding, and his new primal mind was slowly but surely kicking in.
“Let me at least eat first,” I whined as I knew the inevitable was coming.
He smirked and pushed me down to my knees. Before I could even mention that this is not what I meant he pressed his cock on my lips and his hand found the back of my head.
“I’m gonna feed you more of my kids and then I’m gonna fuck you again. I’m going to breed you until you can’t move. I’m gonna give you more and more and more until you beg me to stop. And even then, I’ll keep filling you up.”
He must have known his words were working because my dick had long since bricked and stoned itself to an impossibly hard state. I wanted to protest so badly, but his big spongy head kept getting harder and harder to resist. I finally gave up when he started pre-cumming on my lips. I opened my mouth as wide as I could and let him slide in. I felt like I was in a dream as his giant dick slowly slid in further and deeper. I could feel it expanding my throat as it went past it.
“ohhhhh fuuucckkk …. Dammit … yes … deeper take more!” Frank was gone, his new personality had completely taken over like the previous night.
I could feel it deep stretching every part of me as he slid it in and out and in and out. I loved every minute of it. In the back of my mind …. The part that was still coherent and brimming with scientific curiosity, I wondered how the hell I was taking such a massive cock in my mouth but who knew and who cared. The sucking and slurping just heightened the pleasure for both of us. We never felt so good, and you could tell. Before long he was fucking my face like a second flesh light.
“Mmmmmmmhhnnhh , I’m gonna blow you up even bigger baby. Fuck … oh fuck … here it comes!”
And with that he shot rope after rope of cum inside me. And I could feel it. The cum. It enveloped me. I could feel my belly getting bigger and stretching out. My dick was getting pressed downward harder and harder. I grabbed his strong quads and braced myself for my own orgasm. When it came, I felt his hands on my head pressing me down further.
“That’s ittttt…. Yessssssss… more …. Oh god moreeeeee!!” This beast was getting off on me cumming and I was getting off on him getting off on me.
I had almost passed out again, but it was him this time that went out first. He slumped back onto the floor and passed out in a drunken haze. This was the perfect opportunity for me to clean up and start testing but as I moved something happened. My sloshing stomach started to gurgle and vibrate. My stomach as I touched it sent shockwaves of energy and ecstasy through my brain. It was only then, however, in my own cum-drunken state, I noticed my gut was shrinking.
What happened next was even more insane. My arms and legs started filling up and out. Muscle started stacking on my body and I could feel the heat. You could hear the stretching. I suspected that the serum was definitely in his cum at this point and started permeating my cells. As it did, pleasure soared through my body, and I screamed and moaned in bliss. My cock stretched out to 14 inches and my body went from looking like a swimmer to a body builder in a mere 4 minutes. My pecs were now shelved, my ass was firm and round, my abs went from none to nine and counting and my caves and quads just kept tightening and getting bigger. My balls engorged themselves with cum tightly packed and waiting for my command going from apples to grapefruits made them even more sensitive and made me even more horny. It was like an itch that needed to be scratched. I could hear it calling to me.
Cum and grow, grow and cum …
I shook my head, showered off and ignored my body’s calling. Walking though was a bit of a challenge. My balls colliding with my now powerful legs made it almost impossible to think straight. Every step was a brush against them, and they were just so sensitive now. I was definitely going to jerk off, but I wanted to at least test Franks blood and cum to see the effects and if any side effects were damaging. After all, if they were any at all I would need to fix it right away. I didn’t want to lose my friend or his handsome face. So, I got the needles I’d brought with me and got to work. I just hoped and prayed he stayed asleep long enough for me to get the samples I needed.
