"Dad Are you sure I should do this"

"Of course Shawn don't you wanna be bigger?"

"Well yeah but what if something happens?"

"Nothing is going to happen son, besides you don’t want to be a loser your senior year right?"

"yeah"

"Well Then this stuff is going to work. Once you take this stuff You'll be the biggest guy in school son. All the ladies will be crawling all over you, and you'll be the best at all the sports. How does that sound Sport?"

"It Sounds Awesome"

"Ok Good Now pull down your pants son, so we can inject this into your leg"

Shawn pulled down his pants along with his white briefs, slowly showing off his baby dick. This was the first time he had shown anyone his cock before and he was more embarrassed then ever. Standing at 5"11 135 pounds with jet black hair he was the skinniest kid at school always being picked on even though he was a senior. Freshmen had more muscle then he did.

For the past 2 years he had been eating like crazy not gaining a single pound, so when his dad told him about this experimental drug he was all for it.

He could feel his dad's warm breath touch his cock and balls. His dad smiled at his son's small 2 inch cock and his twig size legs.

"Well Son I'm Sure your going to be happy when this grows haha"

"hehe yeah dad"

Shawn was so embarrassed as his dad stuck the needle in near his crotch area on his leg. Shawn felt the formula flowing through his blood veins slowly traveling around his body.

"Now this isn't instant, but you might feel a little weird son for the next 24 hours"

"Ok"

Shawn pulled back on his pants feeling a little different inside but he couldn't tell what it was. He fell asleep that night dreaming of being one of the preppy guys at school. Getting all the girls attention with his new body no would even recognize him.

The next morning was the first day of school and shawn woke up with a raging hard on. Went into the bathroom passing the mirror stripping all his clothes off

"Holy Shit!"

Shawn looked at his cock.. only it wasn’t his cock.. It was at least 5 inches flaccid now. He stroked it and notice his rock hard abs sticking out of his chest and bulging pecs. He ran to the mirror and stood there in shock looking at his new naked body. His arm's looked like a football jocks and a neck that any girl would love to lick. He stroked his hard 8 pack and furry trail going to down to his newly improved cock.

"Fuck This is amazing"

He reached back and felt his bubble butt pushing his fingers inside rubbing his hands down his leg. He didn't even notice the rock hard 7 inch boner he had hitting against his stomach. He weighed himself on the scale reading a unthinkable 172 pounds.

"Oh My God I gained close to 40 pounds of muscle haha. DAD! DAD You have to Come See This"

Shawn started flexing his biceps in the mirror his cock leaking mounds of pre-cum now. His dad ran into the room and looked into the bathroom to see the best body he had ever seen.

"Check It Out Dad"

Shawn turned around his hard on still throbbing as he flexed his muscle's for his dad. Black crotch hair was covering his enormous penis, and filled up his pits his son was finally a man.

"Holy Shit Shawn That’s amazing"

"I Know! Oh Man I cant wait to show everybody at school. Oh Thank you so Much Dad"

Shawn walked over to his dad pressing his boner right up against him.. Pre-cum drizzled on his Dad's shirt. For the first time in his life he wasn’t embarrassed by his body. He hugged his son's enormous muscle back his hands sliding down to his huge bubble butt. He couldn't believe this happened with one dose. He couldn't wait to see what would happen with 2 doses or 5.

"Ok Son uh you better get going or your going to be late"

"Sure thing Dad"

Shawn winked at his dad and shut the door. He jerked off 3 times in the shower before going to school, cumming more then before. His sex drive was amazing he couldn't believe how horny he was all day. Every hot girl that winked at him made him pop a boner in his tight jeans. He even had to jerk off in the bathroom every period. He had never felt so confident as he pushed his thick pecs through his small shirt exposing every muscle.

Shawn got back home happier then ever. He felt a little bigger then before he went to school. He was finally becoming the guy he always envied.

“Hey Dad”

“Hey Son How was your day at school”

“Oh Man it was so Awesome” Shawn flexed his baseball bicep and winked at his dad.
“I Cant Wait to get a little bigger”

Shawn grabbed some water and headed up stairs. He stepped on the scale reading a full 180 pounds of rock hard muscle. He had always wanted to be bigger but never in his wildest dreams this big. He slipped off his clothes and rubbed his huge balls through his briefs which started to look like huge oranges. He took of his underwear watching his cock bounce up and down like crazy cum drizzling out down his shaft. He couldn’t stop stroking his cock as he thought about the new girl in his P.E class.
The new sensation was unbearable as he cummed uncontrollably into the sink filling it with his man juice.

The next week they injected him with another dose of the formula making him ridiculous 240 pounds of teen muscle. Shawn was actually getting concerned with himself. He couldn’t stop getting a hard on not matter where he was. He would cum right in class without even touching himself. And his now 12 inch boner was hard to hide from anyone and he was going through underwear like crazy.
He did like the way his biceps looked though when he flexed them. 21 inches of rock hard biceps were packed in his arms. And his pecs looked like they could destroy any shirt with one flex. All of his friend started asking if he was juicing or how he was getting so big.

He would look at all the bodybuilder magazines in the store and smirk knowing he was bigger then them. Two weeks later it was time for his 3rd injection

“Ok Son Pull Down your Pants”

Justin tugged down on his shorts pulling them past his 13 inch cock. His bubble butt sprung out from behind as he released it from his underwear.

“Whoa Son Look at You Your getting huge, Cant Wait to see what happens when we inject you with this”

“Uh That’s just the thing dad”

“What Shawn”

“Well Look At me I’m already huge! I have 22 inch biceps and a Body anyone would kill for. And I was thinking maybe we shouldn’t do anymore”

“Oh Come On Son Don’t you like the way you feel”

“Well Yeah its great but..”

“But What Shawn! Listen you have the opportunity to become bigger then any bodybuilder, or any football player at your school. Don’t You want to win this season and get every girl.”

“Yeah ok But Just one More”

Scott watched his son’s cock hang half way down his legs his huge softball size balls could probably squirt gallons of cum. He couldn’t wait to see how huge we would become. He stuck the needle in his leg and smiled at Shawn.

The next morning Shawn felt stranger then ever. His underwear was ripped to shreds and his bed was soaked in cum. He Looked down at his cock and screamed as it was almost touching his knees.

“Oh Shit”

He ran to the mirror and saw a freak, a monster standing there. He flexed his arms which looked like they were over 27 inches now.

“Oh No! Oh Fuck Shit Why Did I do this”

He ran over to the scale and watched the needle spin around hitting 350 pounds.

“Fuck I’m To Big! No This wasn’t supposed to happen”

He flexed his body in the mirror in anger as his boner popped up squirting cum all over his face Running down into his mouth.

“Fuck Look At me I’m A Freak…Fuck I Didn’t Want to be a Freak”


Shawn ran downstairs in huge baggy clothes his face beat red and went to school. All day people stared at him chuckling at how huge he was. Barley fitting into the desk and snapping pencils just by writing. People were making fun of him left and right over huge boners and his cum soaked pants. He hated what he had become, he never wanted this to happen. He ran upstairs when he got home and took off his ridiculously tight clothes. He stood in front of the mirror looking bigger then before. He touched his cock and cummed all over the floor.

He heard his dad walk into the house and started yelling at him to get upstairs.
Scott opened the door to see the biggest muscle freak he had ever seen. His own son was bigger then any bodybuilder complete with a huge muscle ass begging to be fucked and a cock bigger then a horse.

“Oh Shawn Look At You! I Cant wait for you to try this new formula! Its 10 x stronger then the one you have been taking and..”

“Whoa WHAT NO!! I Don’t Want to Be Bigger!”

Shawn Pushed his dad over in rage, his cock getting an enormous boner again
Scott stood up and rubbed his sons’s cock slowly.

“But Shawn This is your dream”

“NO Dad This Is Your Dream! Look At You Dad You’re Turning into a Fucking FAGGOT. I HATE YOU I CANT BELIEVE WHAT YOU DID TO ME”

Shawn Pushed his Dad down on the floor again his boner throbbing again cumming all over his dads face. Scott started licking up all of his son’s cum as a thought came over his head. He wanted the power he wanted to be the most powerful man in the world. He ripped off his shirt licking the rest of the cum off his hand. He Held the needle up in the air snickering.

“IF YOU DON’T WANNA BE HUGE SHAWN..…I WILL”

Shaw’s Dad Injected the formula into his chest inflating his veins to the size of snakes. His whole body started trembling as he inflated everywhere with muscle pushing him off the floor. His Jeans ripped apart setting his huge cock free springing up to his abs reeling out like a fire hose. He stood up and started flexing his arms and chest watching himself grow past 400 pounds.


“HAHA YESSSSS!! LOOK AT ALL THIS POWER! MORRRREEE”

He grabbed another needle shoving It into his leg laughing hysterically consumed by his own size. He neck was flaring out as his body grew disproportional in everyway. He started growing faster now his dick reaching his chest. His arm’s must have been over 38 inches as he flew passed 600 pounds.

“YES MORE! MORRRE!! I NEEED MORE MUSCLE”

He grabbed 2 needles and held them up to his face gazing at the formula. His body was pushing past 700 pounds with the growth no end in sight getting faster with ever passing second. The floorboards were starting to creek trying to hold his dad’s immense weight.

“DAD You Have to Stop You getting to Big”

“NOOO I DON’T HAVE TO DO ANYTHING! I’M YOUR DAD! THAT MEANS I CAN DO WHAT EVER THE FUCK I WANT”

He stuck the 2 needles in his legs his cock flying past his nipples. He was growing to huge as his head started to look outrageously small compared to his body. He was becoming a monster, a freak.

“HAHA FUCK YEAH! NOW SUCK YOUR DAD’S COCK”

He grabbed Shawn’s head shoving it on his 20 inch pric cumming continuously making him drink every last drop. He must have been over 900 pounds now of rock hard muscle packing it on now even faster. His Dad licked his armpits as his biceps grew past 50 inches now. He could barley move his body he was getting so big and it wasn’t stopping.

“AWW I WANT MORE”

He grabbed another one of the more potent formula’s and stabbed it into his leg. Scott’s back was wider then a car now and still expanding outward .

“NO DAD STOP!!! YOU CAN BARLEY MOVE”

“BUT I WANT TO BE BIGGER”

His Dad started inflating with more muscle faster his skin started stretching showing ever vein. He couldn’t stop laughing covering the floor with his cum pouring out of his cock flying past his lips. Scott’s hairy chest was wet with his own man juice slowly uncontrollably licking his own body.. Shawn watched as his dad started growing towards the ceiling to make more room for his growing muscle.

He couldn’t believe how huge he was becoming as he laid there watching his dad turn int a god. A god with balls the size of Tires and his legs would put a tree to shame. He watched his dad lick his giant cock just by sticking his tongue out. His pec’s were in between his pric squeezing against it as they grew.

“DO YOU HAVE ANY IDEA WHAT THIS FEELS LIKE SHAWN?? HUH! JUST ONE MORE DOSE”

He stuck another needle in his leg making his chest expand up towards his head his bones expanding to hold his huge body up. He was becoming obsessed with his growth he didn’t know if his dad was going to stop.

“HAHA I’M GOING TO FUCK YOU SHAWN HAHA! THEN YOUR DAD WILL BE A REAL FAG”

He grabbed Shawn’s ass as he screamed trying to get away from his dad. Scott shoved his 26 inch cock up his own son’s ass. He could feel how tight his son’s muscle butt was as he shoved his cock into the giant man hole.

“AHH DAD PLEASE STOP”

“NOOOOOO I”LL NEVER STOP! I”LL ONLY GET BIGGER! NOTHING CAN STOP ME”

Scotts head hit the 9ft ceiling as he plowed his son’s body growing past 3000 pounds. Shawn started realize he was going to die unless he took more of the formula. He grabbed the formula and squirted it in him. His dad laughed as he felt his son growing on his huge cock as they became monsters together.

His dad stabbed another syringe in his son’s leg and his own. Licking his son’s back and neck as he fucked him harder both of them growing together. He rubbed his son’s pecs pinching his expanding nipples.

“FUCK, YOU LIKE THAT SHAWN”

Shawn didn’t want to admit it but he started to love it as he watched the room get smaller. The feeling of his own fathers cock up his ass sharing each other’s cum. Knowing that he was bigger then anyone on the planet. He could feel his dad’s hairy pecs pressing up against his back as he licked his ears. He turned around and looked at his dad’s face which started looking younger then ever.

He filled his hand up with cum dumping it into his mouth. He kissed his dad sharing there man juice between there tongues filling up there room with there bodies.
Shawn Grabbed the syringe as they pushed through the roof.

“I Wanna Be Big Dad”

Scott rammed his cock faster pumping cum into his son’s ass slowly injecting the formula into there bodies.

Good but a little too fast... Slowing down would build the suspense and all that would COME with it. But, I do thank you for your time, efforts and energy.

[SoraIsTheMan]

I wouldn't mind takeing the drug but the rest is onther story

[MuscleMage]

I've noticed it in several stories, but don't you guys find it irritating when the author writes something similar to "... wakes up with a raging hard-on" and then in the next line describes the penis length as "when flaccid"? Did his dick go soft so he could measure it before it gets hard again?

Otherwise, a very hot story

[thufirhawat]

Very hot, as always!!!
But like MAZIVKAROLY said, it was a bit too fast...It would have been better to make it last more...
Don't worry it's VERY HOT anyways...you have the style, man !!!

[Kitex989]

as always nice work very hot
