They’re too sensitive now

by spacevlad   

Sean convinces his burly husband Jorge to get his nipples pierced for his 40th birthday. The results trigger an unexpected growth spurt much like one that happened in an infamous growth incident a year prior.

Jorge had always been a big guy, even since he was young. A thick, chubby kid growing up, he was always self-conscious about his size. He was teased and his parents had given him a hard time, even as he grew into his thick frame and settled at 6’2”. In his early 20s, he was able to get to the gym a little bit and created a solid foundation of beef, but he was never comfortable at the gym, never serious about it. By the time he was in his late 20s, he had leveled out at 320-pound and thick, with a round, prodigious belly, broad shoulders and barrel chest, and plump quads and huge calves from carrying around his chubby frame for so long.

Fortunately, Jorge found someone who loved his thickness and embraced his size. Even though he often felt insecure and self-conscious about his bulk, his husband Sean made him feel like a catch, like the features he felt shame about were actually strengths.

It was fast approaching Jorge’s 40th birthday, and he was feeling a little past his prime. His gut sagged over his fat pad as he sat down for Chipotle with Sean, and his big arms felt like they were losing some of their heft and solidity. His bushy, dark mustache tickled his nose and his rich, mocha-colored skin was coated with a generous layer of fur covering his chest, arms, shoulders, and back. He was a big, meaty Latino bear, maybe not quite muscular enough to quality as a “musclebear” but certainly packing a lot of heft.

Despite his efforts, Sean hadn’t been successful in dragging Jorge to the gym until recently, despite both of them knowing he had the potential to be bigger. But Jorge didn’t really want to be bigger. He had always been self-conscious about his size; why would he want to add even more?

“So, sweety, your birthday is next week,” Sean said over his double meat chicken bowl. He was fresh from the gym and looking fit and sweaty, pumped and solid, shoulders and traps swollen from a hard lift. “Remember when you said last year that you had always wanted to get your nipples pierced?” Sean said past a mouthful of chicken.

“Well yeah, but that was more like just talking at the bar, I was wasn’t really that serious, I mean, I wouldn’t want them like poking out of my clothes or whatever…” Jorge started, reaching an arm up to rub his chest. “Plus, it would probably hurt right?”

“Well, yeah, but I went ahead and got you a surprise early birthday present to get them pierced!” Sean said as he came around to the other side of the table and nuzzled his short, black beard against Jorge’s neck rolls. Sean didn’t have to lean down too far, as he was only 5’7”.

“But what about The Incident from last year, you know, of that guy like… growing?” Jorge said, sounding nervous. “That was supposedly from getting his nipples pierced right?”

“Do you really believe that?” Sean scoffed, puffing a breath into Jorge’s ear. “That’s an urban legend and it was over a year ago. That was a freak incident of some weird genetic anomaly, I read an article about it on Vice News. Besides, that was just the one guy, it’s not like everyone who gets pierced now magically grows bigger,” Sean said. “Plus, it’s just a couple small bar piercings to start with. The appointment is on your birthday. Sound good?” Sean cooed, obviously excited to get his husband pieced.

“Oh, uh, jeez, wow, yeah ok, let’s do it!” Jorge said, a little nervous and reluctant. Sean was definitely the one in the relationship who called the shots; he made more money, was more sexually aggressive, and usually got what he wanted. Jorge was more than happy to support him and make him happy and try to stay in the background when they were out at the bar or social engagements; that had been his survival strategy for years when was more insecure about his body. Jorge rubbed his nipples a little nervously; they twitched with an excitement he wasn’t expecting.

“Awesome, hmmm, it’ll feel so good babe! And it’ll make those big pecs stand out even more!” Sean growled as he rubbed his big husbear’s thick traps. What Jorge didn’t know was that Sean had been able to track down the guy who had pierced Josh’s last year, the same man who grew into a monstrous giant just a year prior. It was unlikely that it would have the same profound effect on Jorge, but Sean secretly hoped that it would.

Sunday came around, and Jorge came back home with his piercings. He and Sean had gone to the gym to get a nice chest pump, then to the piercing place, so both of them were sweaty, pumped, and horny when they got home.

“Mmmm, Jorge, these look so good on you!” Sean said excitedly as they dropped their bags and Sean started rubbing the big bear’s broad chest.

“Heh, yeah, and it didn’t hurt a bit… if anything it, unf, felt kinda good!” Jorge said, his deep rumbling bass interrupted when Sean brushed against the silver metal bar of his new piercing.

“Yeah? So uh, what if I did this?” Sean said and he grabbed the ends of the metal bar with his fingers and pulled slightly.

Jorge threw his head back and grunted. “Ooof, whoa, yeah, that’s intense,” he said as his cock twitched involuntarily in his tight mesh shorts. “You gotta be, huuuuhhh, careful with these!” Jorge breathed as Sean flicked and teased both nips at the same time.

“Oh ho ho, so it looks like big papi is sensitive and connected after all!” Sean said with delight, twisting the bars and sending another shiver into Jorge’s tall, broad frame. “I told you it might help make that connection and turn you on some more!” Sean said as he started pushing Jorge towards the bedroom.

“Yeah, but I—uuuhhhhfff—didn’t think the effect would be so immediate! It’s like a tingling, burning, electric buzz through—ahhhhhhh!—my whole body and right down to my cock!” Jorge groaned as they went to the main-floor bedroom.

Sean took a moment to strip out of his sweaty tanktop, his pits ripe and musky to match his musclebear husband’s, and stumbled out of his shorts and briefs. His thick, meaty cock tumbled out, half-chubbed and growing steadily. Jorge was covered with a slick sheen of sweat; their a/c had been out for a couple days it was in a humid, 80-something degree day after their chest day at the gym. Sean pushed Jorge down on to the bed. The frame groaned as Jorge’s full weight fell onto it.

“That’s so awesome, big bear, now you know how it feels for me!” Sean said as he paused to flick his own nipples, making his own swelling cock leak into his jock strap and mesh shorts. He shucked both of them off his legs and then climbed on top of Jorge. He straddled his bubble butt against Jorge’s thick, heavy bulge and reached up to keep teasing the newly-pierced nips.

“Unf, wow, yeah, it’s just…. Unnnggg, ohhhhhh, so sensitive!” Jorge groaned as he squirmed under Sean as the leaner, more muscular otter twisted and tweaked his meaty nips, which seemed to be swelling and getting redder and thicker as he played with them more and more. He started feeling warm, even hot to the touch as he sweated profusely. Sean raised his arms up to grip the headboard, a wave of pit stink wafting up to Sean, causing the smaller man to breath in deeply.

“Yeah big pig, grunt and groan for me,” Sean said, getting into it more, calling Jorge a name that was used to bully him in the past but they had reclaimed as a way to get into size disparity headspace in the bedroom that drove them both crazy. “Growing so swole in the gym lately, pig, gonna keep working on turning you into a big boar, how do you like that?” Sean growled as he started grinding his furry ass against Jorge’s leaking bulge. “My big pig,” Sean said, grinding his ass and flicking Jorge’s nips in rhythm, his fingernails flicking the metal rods poking out the sides of Jorge’s increasingly thick nubs.

“That’s right sir, unf, feels so—aaauuuugghhhh!” Jorge groaned, his breathing shaking and gasping as jolts of pleasure rumbled through his body.

“Yeah, you really like this huh?” Sean said as he leaned down, pressing his hands against his husband’s huge broad hairy chest, and buried his face in Jorge’s hairy armpit. Sean rubbed his nose in it, massaging Jorge’s beefy chest as he did, getting that pit stink all over his nose and upper lip. Finally he came up for air. “Such a good boar! You excited to grow bigger for me, boar?” Sean teased as he backed his furry, tight hole right up against Jorge’s thick uncut cockhead.

“Uh, uh huh, unf, I’ve been lifting—ruuufff—hard for you, sir!” Jorge said, shuddering under Sean’s relentless fingers. “I’m your big boar, aren’t I?” As he shuddered, a strange flex in his chest and shoulders rippled across his body, right under Sean’s hands. “So sensitive…!”

“That’s right… and with any luck here, you’ll be growing bigger for me!” Sean purred as he kept rubbing Jorge’s thick nips. Sean felt his hips raise up higher as Jorge’s bulge and belly swelled up suddenly. “Unf, big guy, really getting into it, huh?”

“Unf, I, pppffffttt auuuhhhhhh!!” Jorge groaned as his body suddenly, noticeably, undeniably swelled up bigger all over. Sean gasped and sat back, stunned, as he took in his noticeably bigger husband spreading before him; it wasn’t too much, but he looked like he suddenly had the biggest gym pump in his life, his gut felt full and round, his limbs looked just a big longer, and his shoulders spread wider than ever.

“Whoa, what the… holy shit,” Sean said, as he climbed off his big boar. “Jorge, I think you just grew,” he said.

“Ha ha, very funny,” Jorge said as he rolled over onto his stomach before lifting himself off of the bed. “You’re taking the scene too far, I think, heh,” he said sheepishly before standing up in front of Sean.

Instead of Sean being eye-level with Jorge’s chin, he was now suddenly looking straight-on at his nipples.

The meaty nubs throbbed subtly as Sean looked up, mouth agape, at his now bigger husband. He had to be at least 6’6”.

“Holy shit, Jorge. You… you grew!” Sean said. He couldn’t help but put his hands all over Jorge’s bigger body, exploring the changes, feeling the hardness and fullness of his chest and upper arms and shoulders.

Jorge wriggled away from him. “I—what!? How? No no no no, I don’t…” the burly, hairy Jorge growled, his voice noticeably deeper than before. He rumbled over to the bathroom, the floor shaking a bit, and he looked in the mirror. “Ahhhh! Ay Dios mio…! Whoa…,” he gasped.

“Uhhh yeah man. Look at yourself, just… wow,” Sean said lustfully as he joined Jorge in the bathroom. Jorge was eyeing all the changes and flexing a bit in the mirror.


Jorge wasn’t just the same proportions but bigger—was more muscular, broader, thicker, wider, and taller. He shifted around sidewise and took a deep breath, flexing his chest and comparing himself to the suddenly diminutive Sean. “Jesus, look at my pecs,” said Jorge as he bounced the fur-covered mounds and rubbed his hands over his prodigious gut, which stood out even farther than before.

“I’m so big… damn, I’m huge,” he said softly, almost under his breath, as he slowly flexed his right arm and watched his bicep peak swell up, way bigger than before, a round, hard peak forming on upper arms that were easily over 20 inches around. Then he brought his hands down, his chest bunching together, and hefted the weighty overhang of his gut up and down. New stretch marks streaked across his upper pecs, shoulders, hips, and belly.

“Oh yeah big boar, told you! Growing so big for me, mmmm,” Sean said as he pressed himself up against his bigger, broader husband. “Can’t wait to grow you even bigger now!” Sean said as he reached up for Jorge’s nips, which were an angry shade of red, highlighted by the gleaming metal piercings.

“N-no, wait, I, I don’t know, I don’t know if I want to gr——ohhhhhhh god, unf,” Jorge groaned as Sean reached over and rubbed his fingers in a circle around the meaty nubs. Sean shifted around in front of him and kept prodding, pinching, and pulling on them, using the metal piercings to cause even more pleasure.

“Come on boar, I know deep down you want it, don’t you? You’ve always been a big boy, and now you’re gonna be the biggest!” Sean said, mercilessly teasing Jorge’s sensitive nips.

“Unf, I’m already, hhhhuuuuhhhh oooooph, so big!” Jorge groaned, just in time to see another wave of growth erupt across his body. He could see it himself in the mirror as he surged a few inches taller, bulged thicker, spread wider. His briefs were suddenly, painfully tight around his expanding bulge, his cock longer and harder and heavier than he remembered. “Ohhhhh, too big, fuck I’m getting bigger agai—ahhhhhhuunnnggg!” he moaned as his head started approaching the 7’ ceiling.

“No such thing as too big, boar, remember what I said when we started lifting together? I’m gonna turn you into the meatiest muscleboar out there, right piggy? Still plenty of chunk on you too, heh,” Sean teased as he smacked Jorge’s growing gut, which started pressing him against the countertop. “Yeah, bigger, grow for me, pig!” Sean said as he relentlessly rubbed Jorge’s nipples even more, reaching up to flick his thumps along the bottom and top, up and down, up and down.

“Unnnhhh, no, ung, stop, it’s too—hehehhhh—too much! Too sensitive!” Jorge groaned as Sean kept flicking, the bar piercings pulling the swelling meat of his nipples up and down more and more forcefully.

“Too bad, boar! Plus, I know you like this, don’t you?” Sean teased, pausing to suddenly pinch the sensitive flesh hard. Jorge gasped and his chest swelled wider, his pecs surging with more muscle.

“Y-yeah, but, unnnggg, it’s so… rrrrhhnnnnggg!!” Jorge groaned and squirmed as Sean kept the pressure on and Jorge’s head hit the ceiling with a thump. “It’s too much!” He gasped and panted, totally overwhelmed and overstimulated.

“Hehe, look at yourself grow, pig, flex these big arms,” Sean ordered, and Jorge obeyed, clenching his fists and lifting them up into a huge bicep flex, his pit stink stronger than ever. Sean buried his nose in Jorge’s exposed, hairy pit and he kept prodding the big man’s nips.

“Unnffff, fuck I’m so big,” Jorge groaned, the source of his biggest insecurity now growing right before him, his emotions a swirling mix of anxiety, excitement, uncertainty, lust, and awe. “So BIG!” He brought his fists together and flexed his chest and shoulders; massive traps erupted next to his neck as another explosion of growth rippled across his body, muscles and beef swelling bigger, his thighs ballooning with so much more mass that he was forced to adjust his stance, his head grinding into the ceiling until plaster dust started raising down. “We have to… have to st-stoaaaahhhhh fuuuuuuck,” he roared as another shiver of growth ripped through his chest and shoulders, causing his frame to expand wider in the mirror.

Jorge’s huge bulge pressed uncomfortably against the briefs that were cutting deep into his waist; he reached down with one huge paw and ripped them away from his body until they fell to the floor. He sighed and adjusted his manhood; a 10” uncut cock as thick as a beer can erupted from the ripped briefs, his hardon bouncing against Sean’s furry chest and stomach. He reached down and peeled back the foreskin, revealing his huge mushroom head, glistening with precum. “Unf fuck, I’m so BIG all over!” he grunted and pressed harder against Sean, pinning him against the sink.

“Fuck, boar, we gotta take this back to the bed, I need that cock inside me before you get too much bigger,” Sean said as grabbed the metal rods of the nipple piercings and pulled Jorge towards the bedroom. Jorge was helpless to resist as he stumbled to follow Sean until his forehead smacked into the doorframe, cracking the wood and paint.

“Ooof oww fuck,” Jorge groaned. “Too tall…” he rumbled. Sean just grinned and yanked on his nips again, another wave of growth sprouting him up taller and thicker, as Jorge stumbled into the bedroom. It felt like the whole house shook as he collapsed onto the king-size bed heavily, the frame groaning in protest.

“Oh yeah, YEAH pig, I’m gonna fatten you up good, growing my prize-winning boar, that’s right, squeal for me,” Sean said, getting worked up, as he bounced on Jorge’s enormous body, which was spread out and taking up nearly the whole bed. Sean’s rock-hard cock pressed against Jorge’s expansive, round gut as he seized the meaty red nubs and continued his pleasure-torture. “Yeah, grow for me, boar, I wanna to see MORE!” Sean growled.

Jorge grunted unintelligibly as he writhed and wriggled, trying to buck Sean off his huge frame half-heartedly. Muscle exploded across his shoulders, arms, and traps, a mountain range of size bulging up into round, thick peaks. He took a deep breath and bellowed, his suddenly deep bass rattling the windows as his shoulders spread wider, reaching the edges of the king sized bed on both sides. His enormous, thick calves spilled over the edge of the bed as he stretched longer and taller.

“I need that cock inside me! Get the lube, boar!” Sean groaned as he positioned himself on Jorge’s thick, uncut cock. The huge Latino musclebear easily reached to the side table and pulled out the lube, brought it to his junk, and liberally squirted enough around to coat his entire, massive, growing cock.

“Unnnhgggggg yeah Sean, I’m gonna fill you up so good, such a big cock now, gonna feel amaz—unnhhhhhhhhnnnngggg,” Jorge growled as he thrust into Sean in one clean go, his insatiable bottom swallowing up the entire massive stump.

“Ohhhhhhh god, yes!” Sean groaned as the giant cock invaded him. He settled in on it, twisting and wriggling down further and further until Jorge was balls deep. Sean leaned forward. “You know what it’s time for now, right?”

Jorge shook his head and wrapped his huge hands around Sean’s arms. “No, no more sir, I can’t, I’m already too biiiiiiiaaaaaahhhhhh! Rrrrrrroouuuurrrr!!!” the expanding giant roared, his shoulders spreading wider, his legs stretching until his feet hit the opposite wall of the room, his chest and belly expanding thicker and bigger and rounder as Sean grabbed his nipple piercings and twisted, gently but firmly, the pressure turning on a faucet of growth that poured into his massive frame.

His muscles weren’t the only thing growing, of course. His cock started swelling, twisting, and expanding right inside of Sean.

“Oh fuck yeah I can feel you growing inside me, boar, fuck yes, so big!” Sean groaned, his ass getting stretched further than ever. “Grab me, pig, I want to feel you break me apart, keep growing!” he groaned, lost in lust, his desire for growth insatiable, flicking and rubbing Jorge’s nipples relentlessly.

Jorge grabbed Sean’s arms and started ramming him up and down on his monster cock, suddenly realizing how thin and frail his husband felt in his oversized hands but too overcome with lust to stop. “groooinnnnnkkk yes sir!!”

He bounced Sean up and down for several minutes, both of them lost in the trace of lust and pleasure, heedless to the size that Jorge was packing onto his massive frame until Jorge’s head bonked against the headboard. He was now tall enough to stretch from one wall to the other.

“Fuck, I… I… I’m too big, Sean, it’s too much, you gotta stop, I can hardly—rrrRRUUUunnnnggg—fit in the room! I, ung, I, unf, gotta st-stop and—hhhHHhhhaaaahhHHHUUUUUhhhh,” Jorge moaned, his chubby cheeks expanding and black mustache thickening as more dense hair spread across his chest and shoulders.

“Feels so good, boar, I need more, love watching you grow, my growing fucking pig, fuck yeah!!!” Sean roared, ignoring the pleas of his husband as he sprayed his load all across Jorge’s enormous gut and chest. He shot all the way up to Jorge’s chin, streaks of cum dribbling over the contours of Jorge’s enormous, growing body.

When he was finished, Sean stood up on the mattress and slid off of Jorge’s manhood with a wet squelch. Jorge shivered but didn’t cum, though his cock was red and swollen and angry, clearly needing release. Sean stood at the end of the bed, between Jorge’s feet. The big man was stretched from head to toe on opposite walls of the room, which were 10 feet apart.

“Sean, we gotta, we gotta slow down, this is all too much!” Jorge panted. He shifted his weight to the side of the bed, and the frame cracked and broke, falling awkwardly to the ground in a crash. “Fuck, I’m so heavy now,” Jorge groaned. He tried to stand up, but only got about 3/4ths the way up; his shoulders and back were bent over uncomfortably in their suddenly tiny bedroom.

“Mmmm… when I got these pierced, I was hoping this would happen!” Sean admitted as he stepped closer to Jorge. Sean only came up to his enormous, deep belly button now; Jorge’s swollen, leaking cock smeared precum and lube along Sean’s chest as he pressed closer. “I found the same guy who gave that giant Josh his piercings last year. It wasn’t easy… dude ghosted after The Incident last year and vowed to never do it again in case he was the cause, but I can be very convincing. And now… now we get to see just how big we can push you, pig!”

“Wh-what? No, Sean, I’m, I’m already way too big, like, how am I going to live normally, how am I even going to get out of the house!” Jorge moaned; it was strange to see such an enormous man, towering over Sean and packed with more hard, dense muscle than anyone on earth, complain. His belly wobbled as he adjusted his weight and stepped forward, the house shaking as his huge footstep rattled the windows, cobblestone abs protruding under the thick layer of fat coating his gut.

“Well big boar, there’s only one way I can think of!” Sean said with a cheeky grin, and he pointed his thump upwards and jerked it towards the ceiling. “Onward and upward, big man!” he said and he pounced on Jorge’s nipples, wrapping his legs around Jorge’s ample belly and holding on tight.

“UUUHAAAAHHHH, UnnnFFFFF FUCK!” Jorge groaned as his back and shoulders pressed hard into the ceiling, cracking the surface of it and pushing up into the second floor. “N-no, Sean, I’m too…UuuuuHHHAAAAAGGGGHHHHHHRRRR!” the giant roared as his grown accelerated. He exploded bigger and fatter and more muscular. His delts and traps ripped through the hardwood floor of their second-story guest room as he straightened to his full height, Sean still flicking and rubbing his nips, sheltered by Jorge’s huge pec shelf.

“YEAH Jorge, keep growing! You’re doing it, yeah, MORE!” Sean laughed as he kept playing with Jorge’s meaty nubs and feeling his enormous husband grow in his hands. Jorge shivered and grew bigger, reaching up and pressing his enormous hands against the second-story ceiling. He pushed and the ceiling broke apart in his hands like cardboard as his incredible strength multiplied. Another wave of growth jolted through his spine and soon his head cracked into the underside of the roof, breaking through support beams like they weren’t even there.

Sean had to use his hands now instead of his fingers to grip the meaty nubs protruding from Jorge’s huge pecs, squeezing and pulling and twisting, the metal rods now as big as rail spikes to him. “UNNNGGGG FUCKKKK, HUHHHHH, UMMMPPPHHH, RRRROOOOAAAAA!!!” Jorge groaned uncontrollably as wave after wave of growth tore through his body, thicker and more muscular than a strongman competitor, massive muscles bulging round and hard, his huge gut hanging down and pressing against his huge, hard cock.

At 25 feet tall, Jorge’s head rose up out of their suddenly fragile roof. “Unnnnnggggg, sean, please, too sensitive, you’ve gotta—uuuuhhhg hhuuh hhuhhhhhh fuuuuuuuck!” the giant roared as his pecs and shoulders broke open a wider, bigger hole in the roof, causing the structure to crumble around him as Jorge grew and grew. “I’M SO BIG, TOO BIG, TOO SENSITIVE, FUUUUUCKKKK!” Jorge groaned as his massive cock broke through the back wall of the house and ripped up through what remained of the roof, precum spurting and leaking onto the back yard like a super soaker.

Finally, as he crested the nearby powerlines, Jorge brought his hand up, snatching Sean away from his chest and into his grip. Jorge’s hand covered about half of Sean’s tiny, frail body. He felt like a little action figure in Jorge’s hand, and he squeezed his husband, feeling his strength as Sean squirmed in his hand.

“FUCK, SEAN, YOU WENT TOO FAR THIS TIME!” Jorge boomed, his voice deep and resonant, rattling Sean’s ribcage as he spoke. “I’M TOO BIG NOW! AND LOOK AT THE HOUSE!”

Jorge stepped, his enormous left foot rising up 10 feet, lifting out of the house and crashing through the remains. He shifted his weight into the backyard, his tonnage rumbling the surrounding neighborhood, settling in a wide stance to make room for his thighs, which as big around as oil tankers.

“JEEZ I’M EVEN BIGGER THAN THE TREES, THEY’RE MORE LIKE WEEKS TO ME NOW,” Jorge rumbled as he reached down with his other hand and casually ripped a 20 foot tall birch out of the ground with seemingly no effort at all. “FUCK, I’M STRONG…,” the giant rumbled, marveling at his own power as he clenched his fist, the tree splintered in his hand like a toothpick, branches and debris falling to the ground.

“Heh, yeah, sorry big man, I guess I got carried away,” Sean said, suddenly realizing he was definitely NOT in control anymore as Jorge brought him up to his face. “But you’re my big boar, and I know, deep down, you’ve always wanted this, always loved being big, haven’t you?” Sean asked. Jorge’s thick, bristling mustache twitched into an unexpected grin as he held Sean in his hand.

“M-MAYBE… BUT I, I MEAN, I SHOULDN’T GET BIGGER, RIGHT?” the giant rumbled half-heartedly. “EVEN THOUGH IT FEELS SO GOOD…,” Jorge boomed. He brought Sean down to his chest, the massive pecs spreading before him like a dark, furry wall of muscle. The huge metal rods gleamed in the sunlight as Jorge brought Sean closer to his right nipple. Sean grabbed ahold and yanked it as hard as he could.

“OOOF, FUCK, THAT’S… SEAN WE CAN’T, I—AUUUGGHHHHHHH FUUUUUUCK!” the giant groaned as Sean teased his nipple again.

“Admit it! You want this, don’t you!” Sean said, egging on the big man.

“N-NO… I WANT… I NEED… YOU… YOU GOTTA… RRRRRUUUUURRRRHHHHHH FUCK YEAH I NEED MORE!!!!” Jorge boomed, his voice growing deeper and louder as his attitude shifted and he finally, after 40 years, embraced his big size. “GIVE ME MORE, SEAN, I NEED TO GROW BIGGER! YEAH!” he rumbled as he brought his left hand up and roughly pinched his nipple with far more force than Sean could ever muster in his whole body. A massive surge of growth ripped through him, causing him to surge taller and wider and more muscular, more beef packing onto his body. His chest exploded with size, his quads ballooned out to the sides, and his gut swelled rounder and softer. He shifted his weight, crushing his neighbor’s fences and bushes with a careless move of his foot, and he settled into a wide stance, the ground rumbling under his tonnage.

“FUCK YEAH,” Jorge grunted as he dragged Sean down along his expansive belly to his 6-foot long cock. The monster dick was spurting and leaking pre, dripping and swelling as it grew bigger every second, the musky stench of his crotch radiating off him, growing more intense as he pressed Sean against his thickening member. “GET TO WORK DOWN THERE LITTLE GUY, DADDY BOAR HAS MORE GROWING TO DO AND HE NEEDS BOTH HANDS!” Jorge boomed as he dumped Sean onto his huge cock.

The giant Latino musclebear reached up with his right hand and twisted his other piercing, and size poured into his body, like a tap opening up to full blast as he rubbed, tweaked, flicked, and prodded his own meaty nipples. His huge biceps flexed and pressed against the sides of his pecs as he rubbed and rubbed, hedonistically feeling more size packing onto his monstrous frame.

“OH FUCK YEAH, MORE, BIGGER, FEELS SO FUCKIN’ GOOD, GIVE IT TO YOUR DADDY BOAR, SO SENSITIVE, FUUUUUCK!” he roared as he felt Sean’s body, now not even as tall as his cock was long, squirming and squeezing and humping his cock. “GONNA GET SO MUCH BIGGER, FEELS SO GOOD, SO SENSITIVE, FUCKIN…UNNNNGGG…. UUUUHHHHAAAAAAHHHHHGGGGGG!!!” Jorge roared as his cock exploded. Cum showered down across the remains of their house, now in rubble at Jorge’s feet as he continued to grow and grow.

When it was finally over, Jorge stood tall enough to look over even the biggest trees in the neighborhood. The houses only came up to his knees. He reached down and brought Sean back up to his face. He bristled the tiny man with his dark mustache and stuck out an enormous tongue to lick him up, cleaning most of the sticky white cum clinging to him.

“MMM SEAN YOU TASTE GOOD WHEN YOU’RE COVERED WITH MY CUM,” he rumbled, his voice rattling Sean’s ears and chest. Sean was petrified, too stunned to speak.

“NOW DADDY BOAR’S GONNA SEE JUST WHAT HE CAN DO WITH THIS SIZE AND POWER!” Jorge boomed ominously. He grinned at the nearby houses, which looked so small and fragile. He stepped towards his neighbor’s house, covering dozens of feet with one step. He pressed a massive, thick foot down, his enormous calf muscle twitching, and pushed his full tonnage onto it. It collapsed like a house of cards under him.

“HEH HEH, COOL!” he boomed. He reached up and flicked his nipples, excited by his new size and power, and felt a familiar rush of power crackle through his body, up and down his spine, filling him with pleasure as he surged even bigger. “LET’S HAVE SOME FUN!”
