Hey, my name is joe.  Having just turned 25 and standing at 5’11 with a slim frame i decided it was time to bulk up.  I had a great job and could afford the gym now so i figured its time i used one. i checked a few gyms out and decided on one that was larger, plus it had more hot guys there. I needed something to look at while i worked out right? 

The first day i hit the gym was crazy.  I realized i didn’t know how to use any of the equipment or how to even get started on bulking up, but the day didn’t end in complete failure.  After sweating my ass off doing pretty much nothing i hit the showers in the upstairs locker room. As i began to undress i noticed this really hot guy sitting on the benches watching me.  He was built like a house of bricks i tell ya. solid muscled from head to toe.  And he had a cute face! nice square jaw, darker skin and light eyes.  

He was wearing only a towel and i couldn’t help but look between his legs. They were spread giving me a clear shot of his dick and oh man was it hot. It wasn’t even hard and i loved it. nice girth and big nuts. He stood up and walked toward me. Play it cool i thought to myself.

“hey, i’m trey. you must be new around here.” here said with a smile extending his hand.

“yea, its my first day. i’m joe.” i said sheepishly taking his hand and shaking it. He had a firm grip and masculine hands. I was trying my hardest not to get an erection right then and there, only having a towel on myself also.

“haha, well welcome. i’m sure i’ll be seeing more of you.”  He stood in front of me, his eyes looking me up and down with a grin on his face.  It was so hot.

“same..” was all i could get out. “... welp.... i’m gonna go hit the showers. see you later i guess.” i smiled and walked over to the showers.  He was leaning up against the lockers, watching me leave.

Each shower had its on privacy curtain so i chose a shower closer to the back and got inside.  The hot water felt great over my body, my dick semi hard from my encounter with trey. fuck he was so hot.  I heard another shower start across from mine so i peaked through the crack in my curtain. shit, it was him. He had left his curtain wide open and was standing butt naked in the water, eyes closed as the water ran over his muscular form.  I couldn’t stop it, my dick popped right up to full attention.

His back was to me to start but he soon turned and leaned up against the shower wall.  I gasped as he did so. his cock was rock hard. If i thought it was hot soft, it was nothing compared to hard.  He spread his legs and started to play with his dick. one hand cupping his balls, the other wrapped around his thick shaft slowly stroking it up and down.  man i wanted that dick up my ass.  

Trey started to moan and that's when he looked across the way at my shower.  I realized i had let the curtain open more and was clearly visible now.  He smiled at me and winked.  I didn’t know what to do so i just stood there.  Then he nodded for me to come over to his shower.  Sense there was no one else in the locker room i walked over to him.  He turned me and round and let his cock slide between my cheeks.  

“that bubble butt of yours looks like it needs some attention.” trey whispered in my ear as he reached around my body grabbing my dick and kissing my neck. 

I moaned feeling his dick slide up and down my ass teasing  my hole.  i was his.  “put it in me... mmmmm i wanna feel your dick inside me.”  i arched my lower back feeling his hands slide to my hips. His head was at my hole and i felt him start to push.  i moaned then grunted as i felt his dick pop into my ass. it was think and felt amazing.  he moaned also as he started to slide his big shaft deeper into me.

It wasn’t long before his balls were slapping my ass with every thrust and we were moaning like animals. my cock was on the verge of exploding every time he pushed into me. I could feel his massive member throbbing deep inside me. it was heaven.  Trey started to groan louder. He wrapped one of his strong arms around me, pulling me close. i could feel his pecs against my back. He used his other arm to jack my dick off.  I knew i wouldn’t be able to hold off much longer so i started grinding my ass on his dick. 

“uhhhhh oh joe. your gonna make me blow” trey moaned

“uhh uhhhhh shoot it trey... shoot it deep in me. fuck i’m gonna cum!” i couldn’t hold it back any longer. i yelled out and my cock shot a massive load all over the shower wall and my stomach.  Trey then moaned deeply like and animal and i felt his dick erupt inside me. It was so hot.  i could feel the warmth of his seed in my gut. 

he stayed inside me panting for a few minutes before pulling out, turning me around and kissing me. I moaned as we kissed.  

“so will i see you tomorrow?” i asked.

“i’ll be here at the same time.” he winked.

The next few days i met trey at the gym and we’d work out together then fuck in the showers. it was pure bliss.  After about a week he realized i didn’t know anything about working out and offered to help me out. I was more than happy to accept his offer and he became my personal trainer. He put me on a workout routine to help me gain muscle fast and even showed me which proteins i should be taking.  

everyday we would meet at the gym and he’d work me to the bone. we weren’t fucking as often because he had me working out so hard but i still loved it.  After about 3 months i was seeing great results.  My biceps had gotten bigger along with my chest. i even had abs now. 

One day we where in the locker room after a long workout and i was checkin myself out in the mirror. i turned to the side and noticed that my belly stuck out some.  “he trey, come look at this.”

“what is it?” trey asked as he walked over.

“this” i said pointing to my belly.

“oh that's fine, is it firm?” 

“yea..” i rubbed my stomach with one hand.

“its just your body reacting to all the new protein.” he put a hand on my lower stomach feeling it. “it  could be your working your abs out wrong also, we’ll try a new set of sit ups tomorrow”

Trey and i continued to work out and the results kept on coming. he had even given me new protein bars to add to my muscle gain.  3 more months passed and i was now as big as trey was. I had a strong back, big arms and legs and a great firm chest just like Treys.  My stomach had also gotten bigger though, seeing as all of me had grown it didn’t look to out of place.  My stomach was like a firm beer gut now, big and round. 

“hey trey, will this ever go away.” i asked rubbing my belly one day in the locker room.

“i’m not sure, some guys bodies just don't react the same to the protein, they get a roid gut. we can try to get ride of it if you want after you’ve reached your goal. you wanted to get more muscle right?”

“yeah, i wanna be huge.” i winked at him

“well you will be, plus i kinda like the belly on you.” trey came up behind me and was rubbing my firm gut, his cock between my cheeks growing hard.  I moaned as he rubbed my stomach, it felt so good. my own cock growing hard also. 

We went to the showers and fucked like wild animals.  It was amazing. Trey rubbing my stomach the whole time.  I shot such a huge load that it covered my belly and even my chest and trey filled my ass to the brim.  I decided then and there to keep my belly because trey loved it so much. 

We continued my work out plan and 3 more months passed. i was now bigger than trey was. i was a muscled god from a porno and i loved it!  My belly had also grown bigger too but i didn’t care.  IT had taken on a lot of size and pretty fast too.  It was huge and round with a dark stretch mark up the center and my belly button had popped out.  Trey loved my belly and we were having the best sex of our lives so i didn’t care how big i was. 

I was getting a lot more gas lately also, not just farting, but i could feel it moving around inside me. I asked Trey about it and he said it was normal. i was switching up my protein intake now so my body was just adjusting.

About 2 more weeks passed and i continued my workout. My muscles were growing but my stomach had stop, if anything it was only becoming more firm, if that was even possible.  I figured i must have reached my plateau in my stomach growth. Good thing too, i was massive, like i had swallowed a beach ball. 

Today Trey and i were working out and i had to stop halfway through our routine. I kept getting a pretty bad cramp in my lower stomach, i had been having awful gas lately.  It was bubbling up inside me, i could feel it but nothing ever came out. 

“uhhhhhhhhhh man” i groaned as i lay on the bench press bench, trey spotting me. 

“you okay?” he asked and i rubbed my lower stomach. 

“yeah man, just these cramps. mmmmmm, they keep hitting me”

“you must have to take a massive dump, lets just head up to the showers and call it a day.” trey smiled down at me and helped me up. 

“sounds good. i could use a nice hot shower man” i winked at him and he knew what i really wanted. We hadn’t had sex in a few days and despite my cramps, my ass whole was twitching with lust. 

It took us no time to get up to the locker room and strip down. luckily the place was empty. I hopped in a shower turning the water on before trey could get there.  I leaned up against the wall on my elbows and spread my legs arching my lower back. Trey rounded the corner and smiled. “now that's what i’m talking about” he grunted as he got behind me his cock ballooning up in seconds and pressing against my tight hole. 

I gasped, just feeling his cock against my ass was heaven. “uhhhhhhhh yes... i’ve missed that big boy inside me. mmmmmm” i pushed my ass back and forced the head of his cock to pop into my hole with a groan. “OHHH!!!!!”  he grunted as his dick popped into me.   I could tell he was really horny. He immediately started to pound my as and i loved it. his cock throbbing deep inside me. 

Every time he thrust into me i felt pressure against my stomach. It was a strange pressure but it still felt good. I started to rub my stomach. i could actually feel it pressing out as he pushed deep inside me. It turned me on. 

The pressure started building, my stomach pushing out but staying out. I started to moan as i rubbed my belly.  The pressure started to hurt and i grunted, my stomach growing more and more solid by the second. suddenly it was rock hard and i yelled out as the pressure became almost to much to bare! Then i felt something pop inside me and the pressure subsided as something rushed out of my ass. I sighed in relief, looked down and saw that liquid had gushed out of my ass all over treys dick. 

“are you okay?” trey asked as he pulled his dick out of my ass.

“yeah, i think. What was that man?” i turned to face him, one hand rubbing my ass whole to see what the liquid was.  When i looked at my hand it was just clear liquid. I felt the pressure start to build again, this time faster.  I grabbed treys hand and placed it on my stomach. “feel this” i said.

“fuck....” trey gasped as my stomach became once again rock solid under his hand and i groaned. It hurt, but wasn’t unbearable. It lasted for a few seconds before my belly returned to just firm.  “what do you think that is?” trey asked

“i.. i don't know man” i said, slightly worried. My hands rushed to the sides of my huge mound of a belly. “oh fuck.. its happening again. hmmmmm.” i moaned as my stomach grew solid under the pressure. it was bigger this time though. Trey’s eyes grew wide as he could actually see my belly balloon out this time. i grunted for the few seconds that it lasted then panted slightly as my stomach returned to normal.  some sweat on my forehead. 

The pressure kept coming, but faster and stronger each time. After a few minutes my legs didn’t want to hold me up and i sank to the shower floor. Leaning against the wall, legs spread, Trey beside me, rubbing my stomach. “what's happening?” i asked him but he didn’t know. 

“don't worry, we'll figure this out.” he said reassuringly. this calmed me for a second but then the pressure returned the strongest its ever been. 

“uhhhHHHH!!!!!!” i grunted, rubbing my solid stomach as it pushed out.  Then i felt this intense urge to push. “ ahhh fuck, i feel like i gotta take a shit man.”

“here, let me help you up. we’ll get you to the toilet.” Trey said as he pulled me to standing.  As soon as i was up i was back down again, the pressure had hit.  I couldn’t hold myself up, i fell to a deep squat, bulging belly between both my knees.

“OHHHHHHHH FUCK!” i yelled as i saw my stomach grow outward as the pressure built, the urge to push growing stronger. “i think i’m gonna shit right here man! uhhhhhhh!!!!” The need to push rapidly increasing. 

“go ahead! push!!!!” trey said as he rubbed my rock hard stomach.  I began to push, and soon felt something coming. it was bigger than a shit though. 

“uh uhhhhhhh oh shit man! it hurts!” i moaned as trey rubbed my stomach. i felt my ass whole being stretched open as whatever i needed to pass began to come out. “uhhhh something coming! uh UH UHHHGGG!!!!!” I groaned and push hard. Trey looked down between my legs, eyes wide.

“fuck man.. i.. i think your pregnant!” 

“pregnant?! how the fuck could- AHH!!!!” 

“i don't know but it looks like a baby is coming out of you” 

I knew trey couldn’t be lying, he wasn’t that type of guy, and by the feel of it i was definitely pushing something huge out my ass. I groaned loudly and felt whatever it was pop from my hole. I took a few seconds to breath before looking down and seeing a baby's head hanging from my ass.  Shit this was really happening!

The urge to push soon returned and i felt and saw my entire stomach quiver with the effort to push this baby out. “fuck trey! its coming!” i panted as i could no longer hold back the need to push. “Uhhh uhHH UHH AHHH!!!!!” I grabbed my quaking belly and pushed with all my might!

“you got this man, you can do it!” trey was rubbing my stomach and cheering me on, trying as much as he could to stay calm as a baby began to slide from my ass. 

“ohh ohhh OHHHHH HERE IT COMES!!!” i could feel the shoulders passing now. my stomach rumbling as it pushed the baby lower. i grunted and pushed harder feeling the baby almost out of me. with one final moan i managed to get the child out.  

It slid into trey’s arms, a little boy.   We quickly wrapped him in a towel and trey sat next to me as i panted holding him. “he's beautiful.” trey said smiling at me.  Then he leaned over and kissed me passionately.  “looks like we’ll have to move in together now.” he said with a smile.

I kissed him again, “i like the sound of that.”
