My Big Step Dad Part 3
"Getting Big"

?Awesome where do I Stick It In?

Derek had a huge smile on his face tenting his massive 9 inch boner in his shorts thinking about growing as big as Scott was. Derek quickly lifted off his shirt Scott walked up behind him pressing his muscled body and huge boner against his small back. Derek?s cock pumped up in down from all the excitement his boner getting even harder feeling like it was going to burst. Scott wrapped his arm?s around Derek and grabbed the syringe.

?This is How you do It?

Scott pierced the needle into his left arm pushing the formula into him. Scott could already feel the teenager?s body start to rumble.

?Oh Shit Scott I can already feel it, My Whole body is on fire. Fuck It feels Good?

?Yeah You Wanna Grow huge For Your Muscle Dad?

?OH YEAH?

?Then Flex! Flex as hard as you Can, Show me How Big you can get?

?Oh I?ll Get Big I?ll Get Fucking HUGE GRRRRRRRRRRR AHHHHH?

Scott stepped back watching every vein pop out of Derek?s body as his Body inflated with muscle?s. His pec?s expanded outward filling up his whole upper body his aching nipples grew out slowly getting covered with manly chest hair snaking out of him. Scott watched as the muscle teen flexed his back laughing watching his abs grow out turning into a rock 8 pack, feeling his arm?s swell up. A Huge muscle neck expanded out making him look like a true bodybuilder.

?SHIT THIS IS SO HOT?

Derek watched his shorts push out from his growing cock the pubic hair sprouting out of the top of his shrinking shorts feeling his balls fill up with warm man juice. Scott watched Derek?s legs press against the fabric growing wider filling up with power. Derek lifted up his arm?s flaring his growing pitt hair flexing the huge 15 inch biceps on his arm?s feeling the rush of power come to him. His dick started getting rock hard Scott watched in amazement wondering how his shorts held in his enormous cock.

Scott came over and rubbed Derek?s rock hard abs watching him laugh at the very sight of his new body Scott slowly slid down the teenagers shorts unleashing the huge monster between his legs. It was growing bigger then his own cock at least 12 inches long and still growing bigger. The underwear was drenched in cum the fabric tearing from the ever growing man hood. Derek looked down with wide eyes

?Fuck My Cock Wont Stop Growing!! Haha This is Awesome!?

Derek felt his own cock giving him a wedgie up his own muscle ass. Scott finally ripped off Derek?s underwear in one pull the teen huge cock releasing from the fabrics.

?Holy Shit Its HUGE?

Scott looked wide eyed watching Derek?s inflating testicles grow bigger. The monster cock was gushing torrents of cum inching its way out reaching close 13 inches now.
Derek grabbed Scott?s head pushing him towards the beast between his legs.

?Come On Suck It, Suck Your New son?s cock!?

Derek shoved Scott?s head on moaning from the intense pleasure as his wet lips caressed his thick shaft. He rubbed his blond furry abs guiding Scott?s head further feeling him lick every part of his new penis. He couldn?t wait to show the guys how huge he was now at soccer practice. He would proudly be a skin then a shirt any day now. Scott grabbed Derek?s bubble butt pushing he cock further down his throat trying to suck every part of the massive manhood.

?Yeah Come On Take It All, Put Your Face in My Crotch hair?

Derek shoved Scott?s head further down moaning louder slowly starting to feel up his ass with his own fingers. He slowly rubbed his ass crack bucking his cock in and out of Scotts mouth.

?Ohh Fuck I?m Gonna UHHHh CUM!?

Derek shoved his hand up his ass feeling the warm sperm shoot out of his cock grunting loudly watching Scot try and drink all of his young cum, it squirted out of Scott?s mouth onto the floor still unloading more and more. He shoved Scott?s head all the way down his shaft making him drink all of it wanting the pleasure to never end. He kept bucking his body

?Haha Shit I can?t stop cumming?

Scott dropped on the floor trying to breath warm cum showering down on his muscled body. Derek squirted some into his own hand trying his own man juice wiping it on his chest. The cum slowly subsided Derek fell on top of Scott and Kissed him. He worked his way down his muscled neck and licked up his own cum of the huge bodybuilder chest.

?Oh Fuck Who Knew we would be doing this When I first saw that tight ass of yours?

?Well who knew your cock would put a horses to shame?

?Haha which reminds me when you ever going to let me fuck that tight ass of yours, You know it?s my 18th birthday this Friday right??

?Oh Yeah..?

Scott grinned and kissed Derek on the lips holding the teens tight ass

?Well then maybe I?ll have a Big surprise for you? Scott grinned at Derek ?Lets shower up though big guy. I think I need to get a little bigger which means I?ll need some more of that fresh protein?

Scott flexed his arm one more time rolling over on top of Derek there cock?s getting rock hard there new huge muscle bodies pressing against each other. Scott got up soaked in the teens man juice and headed towards the master bedroom. Derek slowly got up hearing the shower turn on and walked towards the mirror. He looked down at his cock and laughed

?Holy shit its gotta be 9 inches Flacid! Can?t wait for the guys to see me now?

Derek flexed his 15 inch biceps crunching his abs watching them burst out of his stomach. He slowly squatted down watching his cock almost touch the floor looking at the huge definition on his own legs. He slowly started getting an erection feeling the cum start to dry up on his skin.

?Hehe I hope Scott is Ready for some more of my juice?

He grabbed his balls with a cocky look on his face and walked out of the weight room down the hall to the master bedroom. He couldn?t stop flexing his new muscled body feeling the weight of his muscle?s against his bones. He stopped in the bathroom doorway looking at the shower seeing Scott soap up his huge body through the glass shower doors lathering up the soap. Derek felt his cock bounce up watching Scott soaping up his bubble butt bending over to wash his legs showing off his aching crack just waiting to be fucked by his thick cock. Scott turned around and saw Derek?s standing there in the doorway a huge stream of pre-cum running down his huge 13 inch shaft pressing against his rock hard 8 pack. Scott smiled and started rubbing his hairy muscled chest grabbing his own massive balls.

?Well come on Tiger, aren?t you going to help me with something?

Scott slowly soaped up his cock feeling it expand in his hand?s from just the sight of Derek and how Hot he was looking. Derek walked over his pric bouncing up and down with excitement the shaft engorged with huge veins as it pumped to the max. He walked over to the big shower opening up the glass door. Scott watched as the muscle teen walked in slowly closing the door behind him. Derek walked up to Scotts soapy chest and rubbed the crevasse between the two huge pecs. He rubbed his shoulders sliding his hands down his wide back down to the perfect bubble butt and slipped his fingers into his crack. Derek quickly pulled Scott and his body together, pressing their thick cock and balls up against each other. Derek slowly pushed both of them under the running water feeling his own hairy chest get wet against Scotts.

They looked into each other?s eyes and locked there lips together slipping there tongues in each other?s mouth, Derek pushed his fingers in further up Scott?s ass.

?You Like that Big guy?

?Oh Fuck yeah. I want your big cock so bad?

Derek pushed back from Scott holding his 13 incher rubbing his balls.

?You Want this? You Want this big thing in your mouth??

Scott walked up closer and knelt down before Derek?s mammoth pric. Derek watched as Scott rubbed his thick soccer feeling rubbing his hand?s around working his way up to the teens ass. Scott grabbed the inside of the Derek?s crack licking his blond hairy legs working his tongues around his balls. Derek moaned from the pleasure feeling Scott?s warm tongue approach his balls grabbing his legs harder. Derek stopped Scott before he licked his giant shaft grabbing his head.

?No Stop?

Scott looked up

?If you suck my Cock, I get to fuck that tight ass of yours?

Scott Smiled and stuffed his head on Derek?s cock hearing him moan. Derek grabbed Scott?s head pushing him all the way down his shaft. He flexed his own bicep and licked it finally feeling like a real man. He bucked faster feeling hornier then ever he rubbed his abs moaning louder.

?Uhh OH Uhh SHIt STOP? Scott pulled his mouth off the cock

?Oh Shit that was close I almost Cummed??

Derek grinned

?Now Its my Turn?

?You are a horny Dog?

?Yes Sir I am, Now Bend Over and Let me fuck that tight ass?

Scott stood up and turned around rubbing his hands over his crack slowly bending down. Derek grabbed his back pressing his balls up against Scotts manly crack. He slowly positioned his huge cock head with his new Dad?s ass when he heard a load rumble.

?OH SHIT MY MOM!!?

?Fuck You Serious!?

Derek ran out of the shower and started getting his clothes on as quick as he could. Scott was trying to get down his boner trying to pull up his shorts over the massive boner.

?Derek run into the workout room and pack up the steroids I?ll distract her?

?Ok?

?Hello, Anyone home?

Scott walked down the hallway completely shirtless his chest still soaking wet.

?Hey Babe?

?Scott, What are you doing here?

?Oh Derek and I were just working out?

Scott leaned in and Kissed Lisa. She placed her hands on his abs stroking his dark trail.

?I?m so glad you and Derek are getting a long. You have no idea how much that means to me..?

******

Derek ran into the weight room trying to get his 13 inch shaft down. He stuffed the small shirt over his muscled chest lightly covered in his manly hair. His nipples pushed out of the shirt his 8 pack completely visible through the thin fabric. He flexed his bicep and flexed his pecs up and down hearing the fabric tear a little

?Fuck What Am I going to do She?s going to notice something?..Though this is fucking hot?

Derek flexed both biceps his shirt rising up showing off his v shaped chest and perfect blond trail leading down to his obscene bulge.

?really hot? Fuck I can?t wait to see what happens when I take another one?

Derek pulled up his shorts and flexed his legs watching his testicles press through the fabric. His arm slowly reached towards his eager cock when he heard his name called.

?Derek! You Going to say goodbye to Scott?

?Yeah Hold On?

Derek flexed one more time and went towards Scotts duffel bag when he noticed the steroids laying on the floor. His mind flooded with desire as he saw the syringes filled with formula thinking of how huge he can get. Showing off in the team locker room, finally becoming team captain like he always dreamed. His cock started filling his pants at just the thought

?Well maybe just one?

Derek grabbed one of syringes packing up the rest in Scotts Duffel bag hiding the other one under the bench. Derek walked down the hallway strutting his chest proudly looking at Scott?s perfect ass and muscled back knowing he?ll have a chance to fuck him soon anytime he wants.

?There you are sweetie?

?Oh Hey Slugger?

Scott wrapped his arm around Scotts neck flexing his bicep the smell of his muscled body poured off of his. His hairy pecs pressing up against Derek?s head. The mom just stood there laughing not even realizing Derek?s growing bulge.

?Ok Big Guy I gotta go But Uh You wanna Work out again Tuesday after School?

?Yeah Sounds Great?

?Ok Great. Bye Babe See you soon?

Derek watched Scott and his mom kiss his smile went to a frown as he felt a strange pierce through his heart watching his mom wrap her arm?s around Scott. He turned around slowly grabbing the steroid and walked upstairs to his room. He didn?t know what to do wanting his mom to be happy, but he never felt this way about someone. Derek stood in front on the mirror and started posing trying not to think about his problems, He lifted off his shirt with a huge smile on his face flexing his chest hitting the most muscular pose. He lifted up his shorts again and flexed them as hard as he could watching his thighs explode with muscle.

?Fuck and I thought my legs were huge before haha?

Derek pulled down his basket ball shorts over his growing erection. He slowly squatted down feeling his briefs slide up his manly crack squeezing against his tight crotch. He pulled down his briefs flexing his bicep laughing.

?Fuck such a big fucking Cock! Uh I want it so bad?

Derek bent his head down slowly licking his bulging cock head, tasting his own cum.

?Haha Fuck This is Awesome?.. Just a little Bigger..?

Derek grabbed the syringe shoving into his arm feel the formula flow through his blood. He threw the steroid on the floor and hit a pose feeling his body tremble uncontrollable.

?And Now To Get Bigger!?

Derek watched his chest explode with veins feeling his muscle?s pump up. He squatted down feeling the power rush through his body watching his own cock inflate bigger squirting cum out on the mirror. He felt the weight of his balls increase watching his biceps expand in size, the neck muscles exploded on his growing back. Derek laughed thinking of the possibilities watching his cock inch up towards his face. He shoved his mouth over his cock head licking his own cum hole with his tongue his body still expanding his deepening laugh filling up the room.

?So Huge!?

Derek held up his 18 inch biceps and flexed them watching his chest expand chest hair snaking out of his skin. Derek licked his cock shoving his mouth down the thick veiny pric. Grabbing his own balls trying to shove his ever growing cock down his whole throat. He bucked faster shooting his warm cum down his throat moaning in extreme pleasure.

Greetings,
Ive enjoyed finding out that I am not alone in many things that I once thought were unique to only me. I had no clue that anyone thought some of the same things I did. This is my first time posting but Ive been snooping around 4ever. No that I know so many of us share similar views I wanted to pose a question or actually describe myself if you allow me to ust to see if anyone else shares this in common with me. I love muscle on men and never fantasise about me myself getting big nor am I too interested in getting big. I love fantasising about him being the big strong heroe out to rescue me or kicks some ass for me. If My best friend was in trouble I'd feed him the spinach so he could get big and kick ass! I know crazee as I read yalls post I see that most of you want to be the heroes wich is cool but as for me Id rather u come rescue me am I alone on this? stay tuned too you story writers I have some interesting ideas that you may want to run with.
