I had never been a real huge guy. Neither had my roommate, Jon. We'd been roommates for the past two years, and it seemed that everytime we both tried to gain some serious size, it never worked. I guess we were stuck this way forever.
Not that it was a bad thing either. I was the “bigger” one if you want to call it that. I'm 5’11”, skinny, with dark black hair and blue eyes. Of course, I have a pale complexion so that just makes me look even weirder. Jon was a bit shorter at 5’6”. He had brown hair and blue eyes as well, and to me at least, he was cute. He wasn't skinny like I was, but he wasn't real muscular either.
Not yet anyway.
So that's where my story, excuse me, our story starts. It was another normal college day. I had chemistry that morning, and like always, had managed to spill some chemicals on my hands. Of course, I knew the drill. Use this if it's a base, this if its an acid, use soap and water, blah blah blah. But it didn't hurt though. I felt dizzy though, so my professor told me to go back to my dorm and take a rest.
So, there I was. Alone in my dorm room, lying on my bed, feeling like shit. I just stared up at the ceiling, wondering what those chemicals would do to me. I tried to get my mind off it though. You see, I had a fascination for huge guys. I mean, REALLY huge guys. Bigger than any bodybuilder. So I started to think about that. I thought what it would be like to have huge biceps, something that'd strike fear into anyone's heart. What it'd be like to have a huge muscle chest, so huge that when I looked down, I couldn't see my feet. I sat there, closing my eyes, imagining it, feeling a tingling sensation in my cock. I smirked, and started taking off my pants, exposing my cock. It was normal size, about 6” hard, but I've always wanted a huge one. A two foot pecker, or something obscene like that. I felt myself getting aroused again. I watched as my dick started to stiffen. It was then that my head started to ache. Really bad. I had to turn my attention away from everything else. The pain was excrutiating!! Burning, hot, searing pain… I passed out—
When I came to, I looked at my nearby clock. 12:05 p.m. I'd only been out for an hour, but still. I sat up, and looked around. Jon wasn't back yet, so he didn't catch me naked again, like the last time, but that's another story. As I sat up, something didn't feel right. I looked down, and gasped! My huge pecs obscured the view from anything below me! Damn, I still must be dreaming. But as I ran my hands across it, I knew it wasn't. That's when I noticed my arms. THEY WERE ENORMOUS! At least 30” around. I looked in front of me, and gasped. My usual small 3” soft cock was now 18” soft!!! FUCK!! I couldn't believe it. And it was getting aroused. I stood up. I wanted to see myself in the mirror! I walked over to the mirror, and as I saw myself, my cock instantly became hard, smacking me right below my chest.
I had huge, tree trunk quads and calves. It was amazing to think I could still walk! I had a thin waist, probably 30” around. I had an amazingly hard and huge 10 pack, which seemed to jut out from my body. My chest was enormous, my pecs standing out at least two feet! And as I saw my face, precum started to ooze out of my massive cock.
My face would have made Brad Pitt look butt ugly. I had a square jaw, high cheek bones, and a smile that would cause any normal guy to cream his pants right there! I ran my huge hands over my new body, watching all the muscle fibers in my forearms bulge and twitch. I couldn't hold it any longer. I used both of my hands since my two foot long hard cock was so thick, and ran them up and down that huge shaft. Within seconds, I reached orgasm, sending a spray of cum all over the mirror and wall. It seemed to last forever as I shot load after load after load. Shit, I must've shot a gallon! The orgasm was so intense, and it took everything in my power to keep myself from screaming in ecstasy. I didn't want the other people in the dorm to find out! My orgasm lasted ten minutes!!! Finally, I started shooting less, and finally ceased.
Hell I was up for another round! But crap! I looked at the clock again. 12:25?! Damnit..Jon'd be back from class soon. I didn't want to scare him looking like this. I didn't want this room to be a mess either! I imagined my old body, and suddenly I felt my muscles shrinking. I watched in awe (and disappointment of course) as my huge body went back to being small again. I then grabbed some towels, and started to clean up my man seed. I couldn't wait for Jon to come back! I wanted to show him my hugeness!
I was still cleaning the cum off the walls, when I heard a rustling at the door. I gasped, and thanked God that it was still locked, as John fumbled with unlocking the door. I realized I was still naked, and there was still some cum on the floor, but before I could throw a towel around my waist or at least clean up that last gob of cum, John walked in.
“Hey Mike, how was—HOLY FUCK!” He dropped his bookbag as he saw me frozen, naked, and crouching down on the floor, holding a cum stained towel and a pile of cum on the carpet in front of him. John just stared at me as he frantically closed the door, and locked it, then looked back to me. I broke out of my trance and I wrapped the towel around my waist. John had a mean look in his eyes.
“For God's sakes Mike, this is the fifth time I've walked in on you jacking off. Do you think you could maybe show a bit of decency and do it in the bathroom, or at least hold it off for a bit? This is a bit excessive…” He sighed as he sat on his bed, shaking his head. I sat on mine.
“John,” I started, “Something really weird happened while you were at class. I had an accident in the chemistry lab, and…”
“What, you just had to come home and whack off?” He interrupted.
“No…I…fuck, you'll never believe me, I'll just have to show you.” I figured this time I wouldn't get to ridiculous. After all, this power was new to me too, and for all I know, I might not be able to grow anymore. I had an image in my mind of what I wanted to become, and this time, instead of passing out, I got to see and feel my growth.
It started out as a warm feeling all over my body. It felt like the room temperature had just raised by at least 10 degrees, but it didn't make me feel uncomfortable. In fact, it felt amazing. Then the changes started. It seemed to come from the floor and spread up my body as I watched my feet become bigger. Usually I’m a size 10 and a half, but they looked like they were a size 13, no 14! I then moaned a bit as I stretched my legs out, feeling them lengthen, as muscle packed onto my calves. My chicken legs started to blow up, the muscle just packing on there, about as big as my thighs were before all this started. The growth traveled up to my thighs, as I felt them swell, and bulge, and push my legs apart. I threw off my towel so I could watch my thighs grow. They thickened and contorted, each muscle fiber showing through my skin, looking like I had spent years in the gym working them to perfection.
I looked over at John. He just sat there, wide eyed, and I swore I saw a bulge in his jeans. He didn’t say a word as I felt a tightening in my stomach. I looked down in time to see each abdominal poke out. What started out as a light 4 pack grew and bulged and tensed into a very cut and very deep set of 8 pack abs. Then my chest started to grow out. The muscle grew fairly fast here, my vision of my lower body soon cut off by the huge muscle. I felt it with my hands, and I could feel my bigger nipples pointing down to the ground. Of course, my shoulders had to widen to accommodate this newly huge chest, and I could also feel my lats spreading out, forcing out my thin, but not for long, arms out. I felt the growth spread to my arms. It started first in my biceps and triceps, as I saw them swell. I flexed my right arm in front of me, and watched wide-eyed as it seemed to double in size. I reached out to feel it with my other hand, and grinned as I saw it was bigger. Much bigger. I felt my huge bicep, and it felt like steel covered by skin. It was even better than the last time I grew, though I was nowhere near as big. My forearm bulged and tensed, veins snaking up and down both arms. I kept my arm flexed as I looked over to John, noticing he was still awestruck by my growth.
But it wasn’t over yet. I felt my delts and traps rise, my neck thicken. Then I felt my hair grow long, and I couldn’t help but chuckle as I felt the tips of my long dark hair tickle the back of my neck. This time I kept my face the same. Then, as an added bonus, I felt my cock and balls start to swell. My normal 4” softie started swelling and lengthening, until it was 10” soft, with very big balls to match. I let out a deep moan, my voice several octaves deeper as I stood up. I knew I was taller, much taller, probably about 6’9”, judging by the ceiling. I looked down to John, and I couldn’t help but smile.
”Now do you understand why I had to jack off so bad?”
John didn’t say anything for a while, but finally he cleared his throat. “M-Mike…how is this…? Did you just…?” He stood up, and walked forward. He reached out to touch my abs, and hesitated right before the muscle, as if touching me would set his hand aflame. I grabbed his hand in my massive one, and forced it onto the muscle, and he let out a slight moan.
”Believe me,” I started, “This is as real as it gets.”
John could only moan as the crotch of his pants started to get wet. He looked up at me, a wild passion in his eyes.
”Does this only work on you?”
I grinned at the possibility. “Guess there’s only one way to find out…”
