My day started out like a normal Saturday morning off from work. I woke up a little early before my alarm had the chance to go off, and I made my way to the bathroom in nothing but my boxers. I lived alone in a two-bedroom apartment, so I didn't have to worry about roommates seeing me or anything. Not that I would have minded. I turned on the light and saw myself in the mirror. I had fairly large pecs, bulging biceps, and decently shown abs. Speaking of bulges, I had a relatively large one that hung over my meaty thighs. All-in-all, I was a 210 pound, 6 foot tall, 25 year old hunk.
I stripped the grey boxers off and got into the shower. I got a handful of gel and began washing my body and my hair (I kept it pretty short, nearly buzzed until I was done and began caressing my dick and pumping it with my large hands and big muscles and fantasizing about other bulging men with their lips wrapped around my dick. When I finished in there, I dried off and walked naked to the kitchen. I had a large breakfast consisting of four eggs, toast, and bacon. To finish it off, I went to the pantry and grabbed a new mass gainer I wanted to try out. The instructions said I should take two tablespoons of the power in a glass of milk. Truth be told, it was an experimental mass powder I had gotten from a friend who worked in a research lab devoted to enhancing athletic ability and minimizing injury.
He was getting his doctorate in biochemistry, and his focus was on increasing the speed at which cells repaired themselves. The idea was that the powder would effectively increase the speed at which his muscles would grow, but his friend was unaware of the fact that the substance would also decrease the amount of energy (calories) that the body would consume for such processes, and as a result, I would be burning around 1,500 less calories than I normally would a day. I wanted results fast, so I took around a cup of the stuff and downed it. I didn't notice anything immediately. I still ate like a bodybuilder and worked out at the gym like a bodybuilder, but my body slowly began to change. I was actually growing larger by the day. At first, I noticed it in my pecs, my biceps, and my thighs, and I grew hard at the sight of myself in the mirror. My large shirts began to get tighter, and I walked with a new sense of confidence. I was beefing up.
The new weight was steadily piling on. I hit 230, the 240 pounds…. And it kept coming. At first my abs just slowly became less visible. The ridges were becoming filled with fat. My ass grew larger and more rounded, my arms grew bigger and stronger, my back widened, my shoulders beefed up. I didn't think much of it, the changes weren't especially noticeable. Of course, the changes began to come faster.
A week into the change I was already hovering around 280 pounds, I decided to hook up with a guy I met on Grindr named Miguel. He was also built and sexy, and we met at a bar after work on Friday afternoon. After getting drunk, we ended up at my place, and we had sex. It was more than just physical, and I felt my heart rise in my chest when he smiled. The next morning, we woke up with me spooning him, my dick pressed against his ass, and my new small pot belly resting against his lower back. He rolled over and kissed me on the lips and told me good morning. He rested his forehead against mine, and we kissed passionately and slowly for some time. His beard scratched against his face, and his hairy torso was pressed against me. Gradually, his hands moved from out from under my arms down to my belly and my dick. He began to explore my body with both his hands and was kissing me harder and harder, his naked, hairy, powerful body driving me crazy.
After a few minutes of this and breathing heavily, I came, and he rolled me over and put his dick inside of me pushing me towards with every well-placed thrust. Finally he came, and I came for a second time from the exertion on my prostate, and we drifted asleep in each other's arms again. When I woke up a few hours later, the first thing I noticed was his hairy arms wrapped around me and his hand on top my bulky belly. His hands were holding mine, but I felt extremely uncomfortable with the added mass I was putting on. My pecs had blown up too and looked… and felt... thick. Miguel kissed the back of neck and whispered, "I love your size. So beefy” he grabbed my belly “ And your arms… You're so fucking big." My heart felt like it grew, and my hard-on became pronounced. I should have been shocked by how huge I had gotten, but I wasn't. I felt perfectly content there in his arms, and I enjoyed the bigger size of my body.
So what if I was a little softer, I was so much bigger everywhere. At 280 pounds I looked like I had bulked way up… gone far into the offseason... I looked strong as hell. My pecs and arms looked massive, and my shoulders were so broad. I loved the feeling of his fingers pushing into my belly, grabbing my meaty pecs, and it turned me on to feel him turned on, his bulge growing thicker at the feel of me, and his fingers playing with the thick happy trail growing up my stomach. I was usually better about shaving, but I had gotten lazier about manscaping… and the hair seemed to be growing in more and more.
While on one level I felt that my new size and bulk was enough, I still got the feeling I wasn’t done growing… I didn’t *want* to be done growing.
"I think you're sexy too" I told Miguel. He snuggled his body closer to mine. “And I think I’m gonna get beefier” I said.
“You’re gonna get bigger? Than this?” Miguel asked, squeezing me tighter.
“Oh yeah, I have a feeling I’m not done bulking up yet” I said.
That morning I made myself another shake, complete with another big dose of the mass gainer. I wondered what another 70 pounds would look like on my already beefy frame. I downed it wondering how soon I’d hit 350 pounds.
