Eric lumbered his way back to his house. Only a few minutes after polishing off the four additional sandwiches he ordered at the cafe, was his stomach already howling at him to feed it even more sustenance. The huge, hulking teenager wiped the sweat from his brow, barely paying any heed to the extra effort it took to lug all that extra mass he was now carrying around. With the midday heat beating down on him, he took the liberty of undoing the top couple of buttons on the jacket. Without his ruined shirt, his bare chest spread the top of the jacket wide open, the heavy cliff of his huge pectorals on display, a sheen of sweat visible to passersby.
It dawned on the enlarged Eric that when a mother and her teenaged daughter walked by, that he should've felt a little embarrassed when the mom pulled her clearly swooning child away. But he just beamed with pride, an extra spring in his step. He didn't stop to think that it was because of the massive breadth of his shoulder-span, the two of them having to walk onto the side of the road just to get past Eric's enormous frame!
By the time he rounded the corner to his street, the former skinny nerd let out a huge huff, feeling the beads of sweat dripping from the dramatic swell of pecs down onto his rounded stomach. The huge teen grasped at the jacket and undid another couple of buttons, letting the top of his giant gut out. He quickly swiped at the crease underneath his pecs, the amount of sweat pooling underneath them driving him crazy. Eric was surprised to feel matted fuzz against the palms of his giant mitts he called his hands. He'd always been smooth, but now it seemed like whatever process went into making a huge musclebear was changing him in other ways too. He shook his hand, slicked with sweat, and droplets sprayed over the sidewalk. Eric picked up the pace, not wanting his neighbors to see an increasingly half naked musclegutted jock around.
Eric fumbled with his keys, the flimsy sheets of metal almost comically small in his hands. His hands had grown. He didn't know it yet, but while the jacket had enhanced his dexterity with a pigskin (and if he'd ever try, with a girl as well!), everything else was so small that his huge fingers had trouble handling them. Finally, he managed to get the right one and he was able to swing the door open. As he barreled in, he barely felt the way his gargantuan shoulders caused the sides of the doorframe to creak.
The huge teen let out a big sigh of relief as he felt the air-conditioned air hitting his skin, the cooling sweat trapped on his light dusting of body fur prickled him as the heat rapidly dissipated. Eric grunted as he tried to reach around and peel the jacket off. A small sense of panic washed over him as he realized that all that sweat he'd made had practically sealed the jacket to his skin along the shoulders and arms.
"Dang, gonna have to cool down first, I guess," he rumbled to himself. He could barely recognize his own voice, the tone coming out of his mouth so deep and gravelly.
Eric was about to settle down on the couch when he felt the familiar pang of hunger rumble in his stomach. With a sigh, he stomped his way into the kitchen and took a fresh gallon of milk out of the fridge. Without a second thought, he ripped open the seal and began to chug the contents. Normally, his mother would've bought a jug for the whole week and there'd be plenty left over, but after a half a minute of glugging the contents, Eric was surprised to find that he'd managed to consume the entire thing in one go! And still, his stomach was persistent: it wanted more. His mom and dad were out for the weekend, and they'd left him a whole roast chicken to eat over various meals. Instead, Eric found himself tearing into the meat. One leg devoured, then the other, scraping the breast meat off to the bone. The hunger was gnawing enough for him to crunch down on the gristle too!
Slightly sated, Eric returned to the living room and plopped down on the couch, now slightly less overheated thanks to the gallon of milk he gulped down, and just satiated enough that he didn't want to tear into the drywall and begin to eat it after consuming the entire contents of the kitchen. Normally a three-seater, it took Eric a moment, but he chuckled when he realized that his massive frame took up practically half the couch. The frame groaned underneath his immense weight as he leaned back and relaxed a little.
The huge guy unbuckled the rest of the buttons on the jacket and looked down at what further changes it had wrought on his body. His pecs were even fuller than before by the looks of it. Even with a generous layer of padding, Eric could make out a vein running along the surface. The smooth skin was now dusted with coarse hair. He hovered a hand over his chest and felt the way the hairs bristled against his palm. His gut was still present, the jury still out whether Eric liked it or not. Eric crunched down and sucked it in and to his delight, a slight 6-pack revealed itself. He ran his fingers over the blown-out ridges and laughed. So he did have abs after all!
With an errant stroke over his belly, Eric accidentally brushed his fingers against a downturned nipple. Already hard from the cold air of his house, it sent a jolt of electricity down Eric's spine, the hairs over his body standing on end and the space in the crotch of his pants felt just that little bit tighter as something stirred within.
"Whoa!" the overmuscled jock exclaimed, his heart beginning to race. Taking a few deep breaths, Eric paused as he waited for himself to calm down. Deciding that it'd be best to not get too riled up, he tugged at the bulge in his crotch, and put the beast back in, it having slipped down one of his short's pant legs during all the excitement. It was then that the slip of paper he'd gotten from the waitress fell out of his pocket.
Eric's heart skipped a beat. He remembered that he'd actually gotten a girl's number! Biting his lip, he pulled out his phone and entered the number into it before sending out a text. The huge bear of a man sighed, a light smile creeping onto his face as he leaned back and counted himself so lucky. He felt Little Eric begin to stir again, but this time he just tried to ignore it, basking in the thought that a pretty little thing thought that he was attractive.
Not a minute passed by before his phone buzzed. Whoa, he'd already gotten messaged back? He hastily texted her back. It was like everything he texted to her was magic, her replies always a flurry of emojis and flirting. Eric didn't know if he always had such charisma, or if the jacket had somehow made him better at talking to girls, or if she was just really, really into him, but he was liking it! Before he knew it, they had set up a date for tomorrow night, a perfect way to cap off the best weekend of his life!
"Oh man, a date!" Eric laughed to himself as he put his phone down, the butterflies in his stomach twisting knots, he was so excited! And uh... Little Eric seemed to share in that excitement. The huge teen stopped in his puppy-love addled haze and stared down at the enormous tent he was pitching in his shorts.
The hulking, musclebear of a teen winced as he pulled the band of his shorts down, nestling it between the base of his engorged shaft and his balls, desperate to relieve the pressure. Eric was speechless. He knew that the jacket had made his muscles bigger, had turned him into a jock, but he was not ready for the other changes it had made! A dense bush of pubes crowned his pelvis and a towering shaft. He knew he was kind of small down there before, but now he was easily twice as long as he remembered himself to be, and his shaft was well over twice, definitely three times, and possibly even four times as thick as it was before he'd put the jacket on for the first time!
With morbid fascination, Eric brought a huge hand up to wrap around his shaft and gasped when he couldn't get his fingers to touch his thumb. He tried stacking his hands one on top of the other, but found that there wasn't quite enough real-estate to double fist himself. Had he not been so overly grown, what he guessed to be 8.5" would've been plenty of space for two hands, but with as big as his hands had gotten, there just wasn't enough space! Not one to be disappointed, Eric was plenty satisfied with gratifying himself with one hand as his other reached up to play with his extremely sensitive nips.
Before long, Eric was creating a large puddle of pre-seed on the hardwood floor in front of the couch. The air-conditioned air wasn't enough to cool him down any longer, and his whole body was once again slick with a sheen of sweat as he continued to masturbate with his enlarged cock and balls. The bearish brute, now so stuffed with muscle, looked like a mix between an offseason heavyweight bodybuilder and a powerlifter, his low groans of self-pleasure rattling the fine china in the dining room adjacent.
"Aaargh!" he bellowed as he finally came. The first jet spewed out of his big, goose egg balls and erupted from his thick, apple-sized cockhead as he blasted a wad all across the room, the heavy squirt glazing the TV. The next few spilled all over the coffee table, ruining the stack of yet-to-be-read newspapers, adding a few more dollops of creamer into an unfinished cup of coffee, and getting all over the keyboard to his dad's laptop. The last few dollops of seed oozed out of Eric's mini-howitzer, pooling along his ab-pocketed gut as he laid back, basking in an intense afterglow, the most intense one of his young life.
Eric felt himself slipping in and out on consciousness, a goofy grin on his face. Heck yeah... best weekend ever.
***
When Eric came to, he jolted awake, his surprised huff ringing throughout the otherwise still living room. It was still light out, so not too much time must've passed. Blinking once or twice, he shook the grogginess away, feeling the extra mass, that extra momentum his body generated. Oh no... extra mass?! Eric's eyes went wide open, realizing he'd forgotten to take the jacket off! The now even larger man looked down and gulped. He'd definitely grown even more...
