Little Bro Grows Part 4
"I'll Show You Big"

Kyle opened the door slowly almost cumming instantly in his pants at what he saw. His muscle bound little bro was plowing a girl with his 10 inch pric on his tiny bed. He watched Drew's huge muscle butt flex back and fourth, hair starting to sprout out of his giant man crack. A gigantic bodybuilder back holding himself up over her, as his triceps flared in every direction. He saw the girls tongue licking every inch of his blond pecs as she moaned louder and louder.
He couldn't believe the size of Drew's balls! They were beginning to put a horses to shame.
Drew's pecs Moved out of the way unblocking the view of the girls face. It was Kyle?s Girlfriend Lexie being plowed by his own little bro.

Kyle sat there peaking through the door, a raging hard on tenting up his pants. He didn?t care that he was fucking lexie, and even if he did what could he do? Drew was bigger then he was, and still growing. He watched as he sat there rubbing his cock, watching his brother fuck her like a pro.

?Oh Fuck Drew Your So Hot, and So BIG!!?

?Yeah Baby You Like these fucking Muscle?s!! You Want me To Get Bigger Don?t you bitch?

?OH FUCK YEAH GROW FOR ME? Lex moaned louder every time he pumped his enormous legs

Drew started bucking Lexie faster flexing his whole body, veins coursing up his back spreading down to his muscle ass. His legs inflated with power as he pushed his teen body to grow a little bit bigger. Lex could feel Drew?s dick expanding in her pussy, as he flexed his growing biceps laughing harder and faster.

?AWW Fuck! Look At How Huge I AM!!?

Drew grunted harder as his whole body was intoxicated by his own body, Sweat dripping off of his chest into her mouth as she licked every part of him.

?AWW SHIT DREW I?M CUMMING?

Lex was screaming at the top of her lungs as Drew squirted semen up her small pussy, making it overflow out onto tiny legs. She squirmed as she had the most intense orgasm she had ever had. Kyle sat there cumming in his pants, completely entranced by what he had just scene.

Kyle ran to the bathroom and cleaned himself up. The whole rest of the day he couldn?t get out of his head what he had just scene, especially when they were all the dinner table that night. Watching his brother Drew talk to Mom and Dad on how big he was getting. Telling them he wanted to get bigger, which left both of them in shock. He ripped his sleeves flexing his giant 18.5 inch Arms. Luckily he hadn?t grown any taller today. The mom sat there squirming in her own seat staring at her own son?s muscle?s, barley touching her food.

?Umm I?m going to do the laundry? His mom started getting up from her seat

?Oh Mom wait! Here take some of my clothes?

Drew stripped off his shirt, revealing his full on muscle teen chest. He slowly pulled down his jeans over his immense bulge. Everyone was looking at his penis in shock as it stretched his briefs away from his body exposing his blond crotch hair and apple size testicles. The fabric stretched up his ass, stuffing all the ass hair in his muscle crack.
The mom stood there in shock, as she tried not to orgasm right there.
Drew snickered when he saw his mom's face.

?Whats the Matter mom, You never seen this Much Man Before HAHA! I Guess Dad Isn?t doing his Job?

Drew winked at his mom and Flexed his bulging arms up in the air. She walked quickly to the laundry room in silence. Drew just stood there stroking his fuzzy chest and abs worshipping his own body..

?Dad I?m going out for a while?

?ok..?

The dad looked down at his plate of food stripped of his manhood from his own 16 year old son.


Kyle heard the garage door clothes five minutes later and headed upstairs sprouting a major hard on in his pants. He couldn?t stop thinking about Drew, he was just so fucking hot. He found one of his muscle mags on the floor, and started flipping through.
His cock was throbbing against his jeans as he flipped through page after page of huge bodybuilders. He was never turned on by guys before.. at least not this much. He couldn?t stop looking at them, wanting to worship there manly bodies. Kyle was turning into a major fag right there.
There huge biceps, there enormous muscle legs that looked like they could lift cars. The more he looked at these guys the more he realized Drew was getting just as big. He started picturing his brother?s head on every body, slowly pulling his cock out of his pants stroking it as it filled with blood.


?Aw Fuck he is getting so big! His huge Furry pecs and his Big strong arms?

Kyle?s cock was fully hard now as he started strong his cock faster, pre-cum traveling down his shaft to his muscle butt. He licked his fingers and lubed up his ass with his spit slowly sticking them in.

?Aw fuck yeah Drew, Whats that You wanna fuck my ass. Yes stick your whole dick in me, let me lick your huge muscle pitt. Aw Fuck Your Getting So BIG, and Your Getting Bigger COME ON FUCK ME AHHHH, MAKE ME CUM UHHH?

Kyle?s sperm flew all over the magazine as he bucked his ass like an animal. He laid there thinking about what he had just done, jerking off to his own little brother. As he rubbed his sperm into the dark hair on his chest he fell asleep naked on his bed, the magazine covering his dick.


That Monday at school was the worse day Of Kyle?s life. Everyone wouldn?t stop talking about his big little brother, he couldn?t get him out of his head. At lunch Drew sat there flexing his now 19 inch biceps, all the football jocks and girls cheering him on as he pose after pose. Kyle had to get out of there, he took the truck and left the school.


Drew caught a ride home after school and while walking to his door noticed how ridiculously tight his clothes were. He walked into the great room and found his dad standing there in the kitchen.

?Oh Hey Drew I?m glad your home I wanted to talk to you about something?

?Yeah sure dad what you want??

His dad smiled and walked over to him slowly, putting his hand on Drew?s round shoulders.

His dad watched his Son's white shirt fill up with muscle, hair pouring out the top of his collar. His 19 inch biceps were inflating even bigger then before as he started hitting a most muscular pose.

Drew squatted down blowing his jeans wide open exposing his 13 inch cock slowly pushing against his briefs as it inched out from his body. His legs were enormous and so manly. Drew rubbed them with his hand, feeling his ass getting turned on by his own size.
His dad couldn?t handle it anymore and started licking Drew?s huge hairy legs. Working his way with his tongue all the way up to his abs licking his sweaty crotch hair.

Nice, can't wait to see what happens next.

Kinda feel bad for Kyle though.

Another great chapter...

You've certainly established your own style. This reminds me so much of those old Matt/Billy/Sean drawings on the Metabods site. Your stories remind me of the missing storylines to those drawings. Keep up the inspired work!
