All the men in my family are super hung. I am the youngest of 5 boys. My brothers and my dad are all straight muscular jocks over 6 feet tall.

Not me though. I did’t grow until I was much older, except for my cock. My dick got huge but the rest of my body just didn’t grow. I looked ridiculous naked 5’ tall. About 110 pounds, super skinny and my big fat cock hanging 8 inches flaccid. To make matters worse I was always hard especially in the locker room and during wrestling practice. Other guys got hard too but for me it was impossible to hide my huge boner.

My dad was single and raising sons he had from three different women. He was kind of a dog with the ladies but a good dad.

Anyway Once we were over 18 it was common for us to be naked and show off our big cocks. My older brothers sharped the loft above the garage once they were old enough. Dad wanted the guys to sew their wild oats and that loft was perfect.

There were always jocks around we had a weight bench and wrestling mats and a shower, toilet and si k in the open. Guys were always getting naked to change or shower and comparing cocks, challenging each other to jerk off contests. It did’t seem gay, just macho and competitive.

I was definitely gay though I enjoyed everything differently than my bro’s.

The hose was empty and quiet. My brothers were all off at college. Dad had a young girlfriend who kept him pretty occupied.

Dad had a visitor come and stay for a few days. He is a professor, Karl Stevens, giving a lecture at the local college. Dad and Karl were in the marines together. Karl was much older than Dad and looked more like a professor than a Marine. Very tall dark skinned black man with a big mustache, salt and pepper hair. Bow tie, baggy pants, cardigan sweater. He didn’t strike me as having a good body. Dad made us dinner and Jenn, dad’s girlfriend couldn’t make it. It was just us guys. Lots of guy talk about dad and Karl in the marines together.

Dad kept mentioning how strong Karl was. How much he could bench, squat and deadlift when they worked out together. Karl said he still lifts and kept most of his gains. I found myself wondering what the nerdy professor looked like under his baggy cloths. Then Dad mentioned how striking Karl looked in the shower and that all the guys were jealous of his hung meat. Karl looked embarrassed. All I could think of was how hung Karl must be for my dad to be jealous. Dad was very hung and loved to be naked. I was only 18 but I had never seen a guy built better than my Dad.


That nigh I could hear Dad and Karl rough housing . the grunting and moaning woke me up. I listened at the door, and stroke my big cock imaging what they were doing to each other. As moaning and grunting Grew to a climax my cock got harder and pre cum leaked from my piss slit. They got quiet and then quick load moaning and my dad “oh fuck, oh fuck”. I’m pretty sure all three of us came at the same time,

I woke up the next morning with a hard on like I never had before. Listening to my dad and Professor Stevens horse around got me so worked up. I came once while listening to them at the door and twice more on the couch in My step dad’s study . I wanted my step dad to catch me jerking off so bad. Usually when Dad fucks one of his ladies he can’t get out of the bedroom fast enough. I’ve timed it perfectly a couple of times where I edge my cock in the study Listening to my step dad give a lady multiple organisms. and Then he struts out of the bedroom semi hard and the sight of him makes me shoot a big hot load all over myself. He Always acts surprised at the size of my cock and the volume of thick white jizz I shoot all over my self. “ Yeah Son! That’s my boy! “ he would shout.

Not last night. He stayed in his room with Karl all night. They were quieter but I could tell yet hey were horsing around all night.

so I woke up rock hard and sticky like I had been edging all night. I heard Dad’s car pull out of the driveway. Then I realized the shower was running. I think my cock got extra hard and maybe grew another inch right there the second I realized it must be Professor Stevens in the shower and I could tell from the sound that the bathroom door was open. Now was my chance to see what he looks like under the baggy pants, bow tie and sweater. Dad mentioned being jealous of Karl’s big cock so I knew he must be hung, I was imagining a strong muscle bear type body maybe a little chubby but fit. Big round gluts thick arms and quads. I felt a little intimidated, I was so small and could never put on muscle and Karl was over 6 feet and a big strong hung bear. I took a deep breath and ripped off my T shirt and sticky boxer shorts. Feeling really small. Then I caught a glimpse of my hard cock in the mirror. It is really swollen and actually throbbing. Dripping a little. I stopped to watch my self stroke for a minute. That always gives me a little confidence. I realized I needed to hurry if I was going to “accidentally” catch the professor in the shower.

So I took a deep breath and strutted naked into the bathroom. I decided to pretend I thought it was my step dad in the shower. “ sorry Dad, I have to pisssss.....

My eyes were locked on the biggest hardest pectoral muscles I had ever seen. What the professor was hiding was not chubby at all. Karl was solid and huge everywhere. He tapered nicely at the waist. Thick strong abs muscles ripped with the V shaped definition from his obliques to his groin.“Cum gutter” my brother calls them. Karl’s cock was full and thick, I swear to god as thick as my forearm and 9 inches long flaccid The quads were huge. And ripped Karl was toweling off and polite enough to not mention my throbbing hard dick. He turned his back to me and his lats and traps flexed and grew exponentially from his comparitvely small waist. the professor just kept chatting about sports & small talk not even noticing my balls were about to explode. He still had his back to me and- you guessed it - he bent over to dry his legs. Karl’s gluts and hamstrings were more impressive that you can imagine. Completely shredded. He bent over and flexed and Karl caught me staring straight at his asshole. Holding my cock.

Karl was as polite as ever and he complemented my physique. You’re putting on some muscle stud” he said as he grabbed my shoulders. I was looking in the mirror with karl standing behind me. I asked him if he competed in body building. He laughed and said no, but he does show off a little for the young college guys in the locker room. “Can you teach me?” Sure he said.” You know I was skinnier than you when I started weight training. Wow I thought. I decided right then to train hard and get as big as Professor Stevens.

We were both still naked and Karl taught me a bunch of body building poses in front of the mirror.

We posed and flexed for about 45 minutes. Naked. My hard on subsided into a semi . Karl ran his huge rough hands over every muscle on my tiny body. I loved the contrast of his big dark hands on my small pale frame. I have good definition, I know and the professor made me feel good about my size. He held his hands around my 28 inch waist and then ran his big hands over my round gluts. It was then I first realized I was getting a nice booty. “Look at that ass son” “that’s a nice round ass especially in contrast to your tiny waist and ripped abs. He ran his hands over my stomach and chest. I turned to face him and ran my hands over his 8 pack. He had a light coat of hair all over. I loved feeling his pecs and gluts.

my hard on was back. I noticed Karl was still flaccid but was protruding out from his body more. I wondered if a cock that big ever points up like mine.

“ you ever give a guy a bear hug? “ I asked.
“ Would you like that boy? “

With that he picked up my naked skinny body and gave me the greatest hug ever. His python arms could have squeezed the life out of me. I was completely helpless and felt totally safe in the arms of this giant. I started to black out a little and he put me back on my feet. Karl was still holding me against his naked body or I would have fallen over. I looked up at his handsome face, his big salt and Pepper mustache.. “please do it again sir” this time he picked me up higher so we were face to face, my hard cock pressed into his sweaty abs. He gave me a good squeeze and then relaxed.

He kept helping me against him and I kissed him. Didn’t even think about it and we shared a deep passionate kiss. I had never kissed like that before. Kissing girls made me nervous and this was totally natural and spontaneous.

he put me down and I grabbed his hand and led him into my step dad’s bedroom. I grabbed a bottle of lube from the night stand and ran it over his massive cock fatter and harder now then ever. A fat mushroom head began to take shape as I stroked his lubed up cock His fat head poking out from out of his foreskin then the foreskin disappears as his monster cock got real hard and solid. It curved down when hard and I got excited because one of the guys on the wrestling team bends like that and slides right down my throat. Karl’s cock was so fat though. I asked if anyone could deep throat him. He laughed and said he could teach me. He told me to relax my throat and gently worked two of his big lubbers up fingers into my throat for practice. . Karl said he wants me to be the aggressor. “Take as much as you want son. “ “Dominate my cock. “

I tried to swallow the massive cock but gagged. I grabbed a little bottle from the night stand And took a sniff.

That did the trick and I swallowed 6 then 9 inches I could taste his pre cum and wanted more. I took another sniff, sucked 6 inches gently at first and then 8 12 inches. I swallowed him balls deep and sucked as hard as I could and he moaned louder than he did for ny step dad. I blacked out a little and Karl pulled me off his cock, Pre cum running down my chin. I dove onto him again swallowing him sucking him harder than before. Karl held my head in his hand and slowed me down. Hey, hey, hey.

Son, i want you to do something else for me.

I was still sucking but gently as Karl put some lube on my big hard cock and stroked it to a fat solid 10 inches. I had never seen my dick so big. He sat on the bed and pulled me off my knees so I was standing in front of him and he kissed me holding my face he put some lube on my fingers and guided them under his balls and I instinctively I found my way my to his muscular man pussy.

Karl wrapped his legs around my waist and pulled me toward him as he stroked his big dark brown dick. He held my face and stared deep into my eyes smiled and kissed me deep and hard. Our hard dicks frotting together as we made out .

We kissed and stared into each other’s eyes. And I started fingering his tight Sphincter with my lubed up fingers.

“easy son, I haven’t been fucked in years”

my hips and his were moving together in a way the kept our hard cocks grinding against each other and moved my fingers around in his tight muscular ass. I probed a little deeper and a smile came over his handsome mature face. “ YEAH SON, that’s it son, a little deeper” I’m going to teach you how to used that big cock boy. “

I put in another finger. Karl moaned and squeezed me between his legs, “ YEH STUD. Take control of my ass boy.” He lifted his legs higher tiling his pelvic bone up exposing his ass.

I was wearing my dad’s my dad’s chrome cock ring and my dick was really swollen and hard . I loved seeing it like this. My dick right now is bigger than I had ever seen it before. I am surprised it doesn’t hurt. I’m hoping it swells some more.

I put the fat swollen mushroom head of my cock against the tight hole of my dad’s marine buddy and looked into his eyes. Karl put his feet in my chest like he was in a leg press machine as I lined up my dick and worked the head into his hole.

His ass was getting juicy. At first it was just lube dripping out but after some good fingering Karl’s tight ass started secreting a nice slippery juice. I kept the pressure against his hole and let Karl move his hips to take as much of my Cock head as he wanted. He move back and forth on my dick teasing me. I watched his face and his handsome smile and listened to his breathing and moaning to gauge if I should push harder and go deeper.

The big marine squeezed his ass muscles around my swollen cock and then released. It was so fucking tight I didn’t think he was going to be able to take it. Karl reached for the little bottle. I grabbed it for him and removed the top. Karl was still thrusting his hips trying to take more of my big teenage dick. His smile had turned to a grimace that looked like pain and I was worried we would have to stop. I moved the little bottle towards Karl’s face but just the he moved his hips again and knocked the bottle from my hand a couple drips landed on his chest and face. The bottle and most of the liquid landed on my dad’s sweaty gym cloths he left in the bed. The pace of the body builders hips suddenly picked up and the pain disappeared from his face. His big smile was back, but he also looked very determined.

I weight about 120 pounds tiny frame about to plow the ass of a 300 pound 6 and a half fort tall black body builder marine. “OWN MY ASS BOY! “

I realized this guy was so disciplined, always in control and just needed to let go.

6 inches of my 10 inch bone were inside the tight muscular honeypot I pulled out leaving only my mushroom head in. I looked at his face. “ DO IT” he said .

I drove my entire bone deep inside the big alpha stud with all my strength which was met with incredible force from Karl’s entire body. His veins were popping everywhere as he pushed against me to take more of my cock. The handsome smile came over his face as I pushed my cock deep into his core. “Oh Yeah” he moaned. His muscles kind of relaxed. Karl was still moving his hips with mine but I was clearly in charge as I started pumping my cock in and out harder, faster, deeper.
