I woke up drenched in sweat.  I groaned deeply, my hands immediately going to the sides of my big round belly, my shirt clinging to my sweat soaked stomach. was it time? i peeled my shit off and rubbed my stomach, it was still firm but not solid. I groaned again as i felt my belly become rock hard underneath my hands. this had to be it.   All the signs pointed to yes, i was in labor.  I felt my belly button, it still hadn’t popped.  this relaxed me so I laid back in my bed rubbing my naked stomach.  I moaned again, this time louder. i could actually see my stomach bulging out from me this time. it was once again hard, my skin taught, then accompanied by a deep grunt my belly button popped. i watched as it protruded out from my stomach like a button and thought, oh fuck.

My name is kevin. i’m 45 years old, a doctor and not to bad looking. i’m no McDreamy but hey, who is. I was fit for my age, taking good care of my body.  A solid 175 lbs of muscle standing at 6 foot 1.  wide shoulders and a firm chest, not to mention my bubble butt. the guys always liked that about me.  

I worked in a local clinic in a small town. I liked it there. no worries really, just seeing the same people every time for their annual checkups. Leon was one of my favorites. He goes off to college this year though so i wont be seeing him around as much. He's a nice kid, buff and blond. I always loved giving him his physical and today was his last one before college. Everything went fine.

“whelp leon, your as healthy as a horse.”  I smiled at him and he smiled back.  “heading off to college your mom says, that should be exciting.”

leon chuckled “yeah i guess.”

“something wrong? not leaving behind a girlfriend are you?” i nudge him in the side playfully and he laughs. 

“haha no sir its not that its just... well...”

“go oh leon, i’ve know you forever and i’m your doctor, is it something i can help with?”

“its just that i’m still a virgin” he blushes and i laugh.

“don't worry about that, i’m sure you’ll find a nice girl in college. there are plenty of guys your age that are still virgins.”

“its not only that sir, i’ve never even ... ejaculated before” this time his face flushes full on red.

“haha, your pulling my chain. Of course you’ve cum before, what guy hasn’t”

“no sir i’m serious!”  his face definitely looked serious. “okay, you cant tell anyone this okay?” 

“of course, there is doctor patient confideciality. is something wrong? have you tried to cum before?”

“well no i haven't, my family doesn’t let me, they told me i cant and every time i asked they say its to powerful.”

i couldn’t believe what leon was telling me, had he really never shot a load before? i figured it must have been some religious belief or something.  “well, your perfectly healthy so i’m sure when the time comes you’ll be able to ejaculate just fine.”  i couldn't think of what else to tell him. 

“i know sir but.... i don't wanna go to college not knowing what it feels like. To.... ejaculate that is.  I’d never be able to go through with sex, i’d be to nervous. can... you help me?”

I stared at leon. Could i help him? i must be imagining this. a hot young guy like him asking me to help him shoot a hot load? “leon, are you sure about what your saying? i mean, i am a doctor and all but are you sure you don't wanna talk to your family about this?”

“no i don't want to talk to them, they wouldn’t help me i know it. I trust you sir, and you are my doctor so i know that you know what your doing.  Plus in all honesty i’ve never really had a thing for girls.” he smiles sheepishly at me. i could feel my dick growing in my pants. 

“you mean to tell me your gay?” He nodded, was he playing with me? was this all just a game for him to try and have some fun with me? well, if it was i didn’t care. Leon was hot and I wanted him. what better time then now too with him heading off to college and all. I crossed the room to the door and locked it, turning back around. leon still sitting on the examination table in his physical paper gown.  “if your sure about this leon i’ll help you.”

without even blinking, looking straight into my eyes he said “yes, i’m sure.”

“okay, well first we have to get you hard.” i walked up to him and slid my hand under the gown finding his cock and balls. he had a good sized dick soft and nice large nuts, bigger than average. i was excited to see how big his dick was hard. I felt his cock become warm then start to swell in my hand.  he moaned softly.

“uhhh.... i feel ... something sir.”

“yes, that's your dick growing hard.” i kept massaging his cock as it continued to grow. And grow. and grow. fuck he was big! he must have been at least 9 inches long and nice and thick too.  Even his nuts grew some, becoming larger than any balls i’ve ever seen.  “wow leon. your a big boy huh.” he looked down at his dick and gasped. “what is it?”

“oh my god! i’ve never seen my dick this big!!!” his eyes in shock. was he acting? or telling the truth. he did look really shocked. 

“its okay leon.  all cocks get hard like this. be happy about your size, its really big, guys will like that.” i wink at him and he smiles, calming down some so i continue to rub his penis. As leon lays back i remove his gown so that he is completely naked on the exam table.  If my dick wasn't hard before it was now. he is so hot.  If he was telling the truth and really had never cum before i knew this wouldn't take long. As i stroked his cock i watch his face, he moaned more and more, then i felt my hand become wet. i looked down and saw pre cum flowing from his cock. wow, it was a lot. his cock started pulsing and his ball sack bouncing, pulling his big nuts up tighter and tighter. maybe he was telling the truth. “i know something that will help you to cum.”

“mmmmmm what is it?” leon moaned.

“slide your dick inside me” i said as i pulled my pants off.

Leon's eyes grew big. “are... are you sure sir?” 

“yes leon, i’d love to have you inside me.” Before he could think twice about it i straddled his waist on the bed and began to lower my ass onto his hard cock.  I knew i needed to feel his cock inside me and i needed to do it soon, otherwise he’d blow before i got the chance.  i groaned as i felt his cock head against my hole. i slowly lowered onto his dick gasping as his cock head popped into me. fuck he was so big! he moaned loudly and his head fell back as his cock entered me. 

I hadn’t been fucked in so long that before i knew it he was balls deep into me and we were moaning like animals. his cock was so warm inside me. pulsing and leaking more pre cum i could feel it.  I was bouncing up and down on his hard cock faster and faster.  fuck it felt so good!  suddenly leon yelled out.

“UHHHH SIR!!!! fuck i feel something!. uh uhhhhh something is happening!”  his eyes wide looking at me ride his cock.  

“its okay” i rubbed his muscled chest.  “let it happen.”  I could feel his dick become rock solid inside me. his balls tight up against my ass. his cock head swollen huge deep in me. all the signs that he was going to blow. “your going to cum leon. let it out! uhh uhh!!!”  i started to grind on his dick hard and fast

“uhh uh UGH! uhhh oh fuck! uhhhhh!!!!” he started breathing faster, his abs flexing. this was it i knew it. “AHHHHHHHHHHHHH FUCK!!!!!!” he thrust his hips up and i felt his cock explode inside me!!!!  and Holy shit did it explode!  it was a massive load, looking down at his body as he orgasms i could see my lower stomach actually bloating out to make room for all the cum he was leaving in me. shit it was a lot!  my cock was throbbing but  i didn’t wanna bust my nut all over leon so feeling him calm down i pulled off his dick and stepped to the side of the table. 

i could tell leon felt a little awkward which i expected so i let him get dressed and leave before i finished myself off.  He thanked me and i wished him good luck at college and to be sure to come back and visit before locking the door behind him and laying myself butt naked on the exam table.  Oh my god my dick was so hard and on the edge of eruption.  I began to stroke my cock, laying where leon had just filled me. I put a finger to my ass hole, funny, there was no cum leaking out. it had been a while i figured and he was fucking deep inside me. it would come out later.  

I could feel my orgasm building, my cock rock solid, balls nice and tight, just waiting for my cock head to swell up and blow! fuck i felt it, here it comes. my load was building but it was different this time, coming from much deeper. i couldn’t stop myself from moaning and grunting.  This was it! the veins started to bulge on my cock it was throbbing so hard i could actually see it!  pre cum was flowing like a faucet form my slit. i stopped touching my dick and grabbed the sides of the examination table and yelled out in pleasure as my cock shot so hard that my cum hit the celling! 

I fell back onto the table panting, covered in sweat. fuck that was a massive orgasm. I looked up at the celling and my cum. shit, that's never happened before. its like my orgasm came from my lower stomach and worked its was through my dick until it shot out. As i thought i placed a hand on my lower belly. To my surprise it was firm and still bloated out.  I didn’t think much of it. 

The next morning i awoke to my swollen stomach. It was bigger than yesterday and seeing as my bloating didn’t go down any i gave myself a quick examination to check that i was okay. maybe leon’s dick had gone to deep in me. Nope, everything was fine so i got dressed. My work slacks wouldn’t button around my waist. My stomach was too big.  I looked at myself in the mirror.  My stomach curved up from the top of my dick, protruding out at a sharp angle then curving back up slowly to my ribs. I rubbed my stomach and it was warm and firm.  I knew i was okay but i couldn’t help wondering why my stomach was like this.  luckily i didn’t have any appointments today so i pulled on some sweats and called into the office telling them i’d be working from home and just to page me if there was an emergency. 

I sat at home reading up about different stomach conditions. As i read i kept getting up and going to the kitchen for a snack. i’d never been so hungry, my stomach grumbling for more and more food. By the end of the day i had read everything i could find and still couldn’t figure out why my stomach was so swollen. Needles to say i didn’t do my P90X abb ripper workout that night.  Seeing as i couldn’t really do anything right now I headed up to my room to get ready for bed.  as i changed i caught a glimpse of myself in the mirror, was my stomach bigger? i placed a hand on my belly and rubbed its firm round surface, i think it is bigger and definitely rounder. I walked up to the mirror for a closer look and discovered a light stretch line forming. Going from the base of my dick up through my belly button.  I tried not to think about it and got into bed and forced myself to fall asleep. 

The next day i woke up and the first thing i saw was my stomach. it was twice as big as yesterday.  My shirt had actually stretched up over my belly through the night and was now resting on my chest, exposing my belly to the world.  The light stretch mark was now a dark brown also.  Something needed to be done. It was sunday so the clinic was closed.  I drove into town and went into the building. I decided i should give myself a sonogram to make sure i was really okay, i just hoped nobody was working overtime today.

I pulled up my shirt and squirted the cold gel onto my exposed gut.  I then slowly rubbed the device around until..... what? i dropped the handle in shock. there on the screen was the definite figure of a baby. a baby inside me!!!!! And in only two days? i didn't understand, i was a man, and this should take 9 months not 2 days!  I ran from the building and jumped in my car. I sat in the parking lot for a while racking my brain then i gasped. I put a hand to my stomach, the baby had kicked. It actually kicked inside me!  this was real.  I started to panic, what should i do? I took some deep breaths to calm myself then realized i needed to go to Leon's place and figure this out. Pulling on a baggy sweatshirt to try and hide my stomach i drove over to Leon's.  I got out, knocked on the door and his mother answered. 

“oh hello, is leon home by chance.”

“no kevin, he left for college this afternoon.” his mom replied with a smile. “what can we do for you.”

“im not really sure honestly, but can you explain this to me?” I lifted my clothes and reviled my pregnant stomach. Her smile faded as she saw my belly.

“quick come inside.” and she stepped aside for me.  I entered their home and we went to the kitchen. i sat at the table and she began pacing back and forth. “i had a feeling this would happen someday, well not with you kevin but non the less happen.. oh dear...”

“well?... can you explain this to me?” i said as i rubbed my belly. the baby was moving inside me. It was the strangest feeling. 

“Your a doctor kevin so i’m sure you know that your pregnant.”

“i was afraid you’d say that. Isn't’ there anything you can do, make it go away or something?”

“here let me see your stomach.” She walked up to me and once again lifted my cloths to show her my belly. It had gotten bigger. I could tell i was about 8 months pregnant now. she rubbed my stomach, feeling the curve from the bottom to the top. Poked it a bit in certain places then looked at me with a small frown. “i’m sorry, but your to far along. there is nothing i can do, maybe if it were yesterday i could have reversed this but now there's only one way to get that baby out of you.”

“... and what is that” i said nervously.

“your going to have to give birth.”

I almost fell out of my chair, birth? me give birth to a baby? i couldn’t believe my ears.  “could you at least explain to me how this happened?” i said grabbing my stomach.

“yes... yes you deserve that much.” she began to pace again. “lets see, how do i start. Well the men in this family are... different.  There sperm is very powerful. yes i know it sounds crazy but its true. You see, if their seed mixes with a woman it works normally, your a doctor so you understand that. But if they place it in a man, it well, does that.” she pointed to my stomach. “that's why we never let leon ejaculate. we were trying to protect him and whoever he might have sex with.”

I didn’t really understand yet i did. i realized that i was actually pregnant and would have to give birth to leon’s baby. “so.. when will i know its, time. Time to give birth?”

“you’ll know leon, your a doctor for goodness sakes. Oh but it wont happen until your belly button pops. That's like a timer, letting you know your time is up. that will happen soon i’m sure but its different for everyone you know.”

I stood from my bed, the sweat still coming from my body, rubbing my laboring stomach. So that's how i ended up in this position.   I grunted and felt my stomach drop. i could actually see it get lower. Fuck it wouldn’t be long now. I went to the bathroom feeling the need to pee or something. I sat on the toilet, and another contraction hit. i groaned rubbing the sides of my belly. this one was different. it got stronger, pushing my stomach out from me. i could see my belly bulging out more and more. I began to moan then felt release as fluid emptied from my ass into the toilet. a huge gush of it.  My water broke. I had a few seconds to breath before a massive contraction hit, starting in my lower back and working its way around to my solid stomach. I yelled out this time. bending over my belly as i sat on the toilet. I took deep breaths waiting for it to pass.  

I stood and walked back to the bed, passing myself in the mirror. I was quite the site. A naked man with a huge 9 months pregnant belly.  I watched as the sweat from my still muscular chest formed rivers down my stomach and around my popped belly button.  I thought about what it would be like to push this baby out of me as i rubbed my stomach. I’m a strong guy so i knew i could do it. Then another contraction hit. I doubled over, it was a big one, my stomach once again pushing farther away from my body. I groaned and waddled over to my bed. 

I managed to get onto the bed with some pillows propped up behind me for support. I was rubbing my stomach breathing deep, legs spread.  Any moment now i knew i would be giving birth to a baby, to leon’s baby. I felt the baby moving inside me. i took some more deep breaths then felt the baby move even lower, you could actually see my stomach bulging out and dropping down as i lay there.  I grunted, fuck the baby was starting to push on my prostate, my dick growing hard. THen a contraction hit and my stomach tightened around the baby. uhhhhh fuck! i was moaning deeply grabbing my stomach.  Suddenly i felt the urge to push. i reached down and felt my ass hole. it had gotten wider but definitely wasn’t big enough to let the baby out yet so i grunted and tried as hard as i could not to push. 

About six contractions later i couldn't resist the urge to push any longer. i was covered in sweat and my ass was ready to deliver the baby. my cock was pulsing because the child was now pressing directly on my prostate.  i started to moan as i felt a big contraction coming. this was it. i was going to push this time.  I yelled out as my stomach once again swelled up that little bit more and pushed the baby down.  I spread my legs wide and felt my cock almost explode!  The child was sliding past my prostate and through my ass!  

“uh uHHH AHHHHH FUCK!” i grabbed the sides of my stomach moaning more and pushed again. I felt the child's head slide out of my open ass hole and them I screamed in pleasure as my cock erupted a huge load all over my belly.  I knew it wasn’t over yet though. i had to get the rest of the child out of me. My cock still rock hard as the shoulders of the baby pushed on my prostate now. It was strangely erotic. rubbing my pregnant belly like it was my swollen erect cock.

“uh ugh! uhhh ah shit!” another contraction was coming and it was a big one again. i brought my knees up to the sides of my stomach and moaned as i pushed my chin down against my chest pushing this child out of me.  Suddenly i felt my dick begin to ejaculate again as the baby slide even more out of me.  “uh OHHHHHHH!!!” i yelled out as more cum splattered my stomach. The baby was almost out. I felt another contraction and i was determined to make this the last one. My entire belly quivered as this contraction hit and swelled up more around the baby.  My stomach rock hard and shinny with sweat. I yelled out as my face turned red with the effort of pushing and felt the child pop from my ass and i feel back onto the pillows panting. 

I didn’t have long to relax though. I needed to check the baby. i quickly cut the cord and wrapped the child up in a blanket to keep it warm as it started to cry.  I had done it. i actually gave birth to a baby. a little boy.  I had no idea what i would tell leon when he came back from college.
