Brothers

“Hey, you got a package.”

Derek rushed to the front room of the house at his brother’s call. Getting close to the front door, he saw his older brother Robert holding up the parcel that had just arrived for Derek.

“So, what is it, shrimp?” Robert asked in a condescending tone as he casually tossed the box in his hand despite the fragile sticker stamped across the parcel. Derek stammered a bit as he watched the casual way Robert played with his delivery.

“It’s just something for my collection,” Derek said, scrambling to catch the box as Robert tossed it over his shoulder, the muscular brother leaving to go back to the living room, speaking what a waste of cash as he passed the smaller sibling. Derek sighed but was thankful that Robert didn’t make things too hard for him.

Heading off to his room, Derek shut the door behind him before getting to work opening the parcel, praying to whatever god that Robert didn’t break what he had ordered.

“Thank God,” Derek said with visible relief as he saw what he had ordered had survived his brother’s abuse. In the box was a foam layer that held a bottle within the cutout shape. Lifting the bottle, he smiled at it.

“Jumbo Gro! A M.A.S.S. Inc product” The tag read, filling Derek with excitement as he knew this would help him with evening things out with his brother. No longer having to deal with being pushed around by the more muscular sibling, this tiny bottle promised Derek a chance to put the more arrogant Robert in his place.

“Hope it tastes good,” Derek said as he sat back on his bed, popping open the bottle before gulping it. Immediately the sweet, candy-like taste filled his mouth before the liquid flowed down into his stomach, where it rested and filled him with warmth. Lowering the bottle with a sigh and a small burp, Derek corked the bottle before the heat began to spread through him, already signalling the growth that was kicking in.

Biting back a moan, Derek brought his free hand to his flat stomach as it began to puff out and swell under his touch. His lithe form stretching taller in spurts as his torso and waist thickened out. Derek’s shirt was getting tighter, riding up his swelling gut as his once flat chest began to bulge into a set of plump moobs. Derek struggled to keep from moaning with excitement and relief as his feet burst through his shoes with his limbs thickened out. The growing man wiggling his thicker toes, ripping through his socks as the bed beneath him creaked from his increasing mass.

“Fuck..” Derek moaned as his body was hit with another growth spurt. The growing man was lifting a thickening arm, his shirt finally tearing open as his moobs were released, slapping against the top of his growing gut. Derek’s broadening ass swelled beneath his widening back whilst his heavy thighs spread across the steadily shrinking bed. Derek brought an ever-increasing hand to his belly, running it as he noticed the light body hair he had was not significantly denser, giving the thicker treasure trail and appraisal. Relaxing under his touch, the growing Derek licked his lips, feeling the curl of his facial hair, before heaving up a resounding belch. The eruption of gas shaking the contents of his room like a small earthquake, along with causing his fattened form to jiggle.

“The Fuck? What the hell are you doing up there?” Derek smirked at Robert’s shout before grunting deeply as he got to work getting off his creaking bed. Standing up, the fragments of Derek’s clothing burst off with only his stretched out briefs trying to contain his swollen ass cheeks and thick thighs that were easily wider than his waist had been. Standing tall, the giant man smiled at how much bigger he was now, not to mention significantly fatter than before, as he now looked like truly giant sumo with how fat he was

Heading towards the now smaller doors of his room, unable to resist relishing the way he now waddled with how fat his thighs were and how the floor shook under each footfall. Before he could even attempt to squeeze his enlarged form through the doorway, Derek stopped and looked at the small bottle resting in his baseball mitt sized hand. Deciding it wouldn’t do for Robert to find it, Derek stomped towards his chest of drawers and pulled open his underwear drawer, smirking at how small they were now, before stashing the bottle under cover of the pitifully small clothing.

With the bottle safely hidden, Derek turned his ample body towards the door to show off his size to his now little brother. Getting to the door, Derek smirked with his head and broad shoulders above the doorframe whilst his wide gut, thick waist and huge ass were too big to get through the usual way. Opening the door and being careful not to rip it off its hinges, the giant man crouched down and moved through the door shoulder and side rolls first. Getting halfway through, one of his heavy moobs and thick legs got through the door whilst the widest point of his gut and ass began to get wedged, the doorframe creaking as the giant man began to force his way through. The immense Derek placed his hand against the wall and started trying to push himself through, causing the wall and doorframe to crack under him as he forced himself through.

With a crack of the now broken doorframe and wall, Derek got through into the hallway. His heavy body was wobbling about as he stumbled a bit, shaking the entire house. The huge man was feeling proud as he glanced back over his shoulder, seeing the wrecked doorway behind him before he shuffled down the hall towards the stairs. Derek relished how his wide hips brushed against the bare walls of the hall. Each step he took shook the house. Getting closer to the stairs, Derek smirked when he caught the sound of his brother shouting in confusion, clearly wondering why the place was shaking.

“What the Fuck?!” Robert exclaimed, standing at the foot of the stairs as he saw the enormous giant blob-like man that was once his tiny brother. Derek stomped down the stairs, relishing the feel of his fat feet breaking the stairs under each heavy footfall, forcing Robert to hold on against the wall as he stared in shock at the giant before him. It wasn’t long before Derek was standing before Robert, forcing the more petite man to have to look up as Derek’s swollen gut pinned the stunned, muscular man to the wall.

“Hey ‘big’ bro. You’re looking pretty small.” Derek said with a deep chuckle before grunting as he let out a resounding booming fart, shaking the house as his gas stunk the room.

“Jesus! What the fuck happened?” Robert coughed out before groaning as Derek leaned into him more, unable to push the massive man off as the wall behind Robert creaked audibly.

“Well, I just had a growth spurt. And I think we’re going to have some changes here.” Derek chuckled deeply, feeling excitement beneath his gut as he enjoyed how easily he overpowered the once stronger Robert. Before Derek could begin the plan for what would happen, his stomach let out a deep gurgle with hunger. “But for now, I think we’ll start with a meal. Better get to work feeding me, Rob.”
