Male Hip Expansion - Tumblr Posts

Short-ish piece because I can't get this super yummy image out of my head.

Trans male, macro growth (house-sized and up), hip expansion, building fucking.

Don't tag as c*ntboy.

(fwiw: I'm a trans guy.)

He was flushed all over, so wet it was starting to puddle in what had once been his backyard. Jack's ludicrously large hips swung back and forth as he tore a bigger and bigger hole in the side of his house. The strap-on had grown with him, big enough now to leave a hole the size of a bay window in his second floor. Past the unused bedroom he first penetrated, his cock plunged into the narrow hallway, making him moan in erotic agony. His hands were starting to sink into the roof, nails leaving crumbling plaster, and he had to move them to the ground on either widen of his house. He had grown big enough to fuck his house, to rest comfortably behind it, his waist edging more and more toward being wider than the building itself. His hips had long since passed that goal--they had already been twice the width of the doors when he forced himself through a wall after his head started breaching into the second floor. His fat ass kept his body in motion, in and out, as he inched higher over his former place of living.

His pace picked up again as the harness started to pinch around his thick thighs, drawing tight as he began to outgrow the strap-on itself. It felt increasingly small against his front, the vibrations softening even as he desperately ground his clit against the back surface.

He came, not for the first time, then, leaning back so the dwindling dildo was at a 45 degree angle from the ground. The dripping on the ground became a steadier stream as he tore up chunks of ground behind him, arching forward, head tossed back. Jack moaned long and deep as the pillars of his legs dug trenches into the ground, his waist rising over the roof of the house. When he was big enough to really look over his house, even sitting down, the strap-on broke off, a piece of plastic the size and width of a fallen tree trunk in his swampy backyard.

His knees crept along the sides of the house and his new size--three or four times larger than he had been moments prior--forced his hairy bush over the top of his house. He expanded along the ground, hips wide and heavy enough to leave an imprint the size of a lake, until he was coming on the roof rather than the ground.

The growth tapered off there, leaving him hornier than ever with very little around to please him. The fallen strap-on wasn't even as thick as his wrist. Jack reared back, plush ass pushing against his heels, fingers tweaking his nipples. He moaned again, significantly more loudly, as he bore down on his cornerbacks residence and began to grind against it.

Loose roof shingles fell to the ground trapped in droplets of cum if they weren't trapped between his impossibly thick thighs or stuck on the wetness of his crotch. At first Jack only lightly grazed the top of the house, but as he started increasing in size again, the pressure became more and more until he was grinding his clit into the roof. It fell off in sheets, fluid leakng through into the already ruined upstairs. He supported himself only by the knees as his hands grasped at his chest. His moans rose back and forth as he brought his monstrous clit against the house again and again, bearing into it. The roof gave way to his room-sized head (comparatively, the size of his thumb to him) as he pressed it desperately against the second floor. The deteriorating walls became rough nubs and ridges that rubbed against his sensitive sex as he pushed it over the same patch of floor again and again. His shadow loomed heavier than ever, hips more than twice as wide as the house, with an ass approaching the size of a small town.

Jack came again, hard and heavily, growing until his head grazed the clouds sitting down and his house was nothing but damp rubble underneath him. He glanced toward the city as he rubbed two fingers against his swollen clit. There was an aching emptiness in his hole and no person, no toys big enough to fill it. Rising to his feet shook the ground, bringing down power lines and bridges. Jack eyed the tallest skyscraper in the city as he ambled toward it, leaving drops of cum large enough to create new lakes beneath him.

It was amusing to look at the skyscraper and recall being small enough to fit inside it--because right now, it looked like the right size to fit inside him.

Part 2?!

Featuring: growing mega-giant trans guy fucking a skyscraper into oblivion, drowning a city in cum, and playing with himself once he's too big to play with the environment.

Don't tag as c*ntboy.

The empty skyscraper was still hip-high to Jack as he approached it. Cum flowed down his thighs, thick enough to crush a building. He stood there, looking at it, legs putting enough pressure on his bulb to keep it shuddering and to keep him growing. The skyscraper still did not dwindle quickly enough before him.

Jack approached it and thrust his hips against a sharp corner, driving his clit into it and giving him an extra ten feet all at once. The building reached the tops of his thighs now--he was big enough to straddle it, but still too small to fuck it. Jack bent his knees slightly, his mountainous butt swaying beneath him, and continued grinding against the hard edge of the building. It crumbled beneath him, and his knees were forced to bend lower and lower as his insatiable growth kept its pace.

Finally, the corner of the building crumbled to barely anything, a pool of cum deeper than the front door was tall around it, Jack deemed himself the proper size for his next step. On legs shaking with pleasure he straightened to his full height (now easily far beyond a mere thousand feet) and stepped over the skyscraper so it was positioned just right beneath him.

Contemplating his next step made Jack almost orgasm, letting loose enough hot liquid to douse the entire building and properly lubricate it. Careful to spread his legs--which was easy enough, given the span of his hips nearing the height of the tower--so his thighs wouldn't destroy his toy, Jack slowly squatted down.

The roof of the building pushed past his entrance, making him moan in a voice deep enough to rattle any surrounding structures. Jack struggled to stop himself from inserting the whole thing instantly. The incessant growth of his body helped that--every relative inch he brought inside himself, he seemed to gain two relative inches on the size of the repurposed skyscraper. Thick droplets of cum ran down the slick windows of the tall building, contributing to a deepening lake that was consuming most of the downtown area. Jack lowered himself a little further, the top of the building just barely beginning to scratch the itch deep inside him. He moaned again as he grew past the point where his toes outsized a modest townhouse. The edge of his left foot was starting to sink into the underground stations crisscrossing underneath the city's financial district. By the time the top half of the building was inside him, Jack's chest was rising above the clouds. Steadying himself, Jack stopped bracing his arms on his thighs (each as wide as three blocks) and trailed his nails against the sensitive surface of his nipples. He instantly grew enough that he had to sink to his knees to maintain the skyscraper's level of insertion.

Jack brought himself lower and lower, his hungry hole consuming more and more of the tower, which was starting to become too small to do much. When his lips brushed the ground, Jack clenched hard, his strong inner walls compressing the building into a tall collection of rubble. He knew it should have hurt, but the broken metal beams and cracked concrete scratched us walls just right. Cramming a finger in after the building, he pushed its remains right against his g-spot.

Jack drastically outgrew the city, his looming legs long enough to reach two towns over, each immense ass cheek more than twice as large as the entire city. The entire area flooded with a deluge of cum that was heavy enough to break through the streets, washing bits of buildings and cars into the deepening hole in the ground. There was no longer a city beneath Jack; only a city-sized lake that stood monument to his massive growth.

Yet he was still not done growing.

Jack planted his ass behind the steamy puddle, laying his back down on the ground. His head reached halfway to the mountains now, meaning the remains of his own house were trapped somewhere near his shoulder blades. The ground sunk under him as he continued expanding against it. As he grew too large to feel much more of the skyscraper inside him, Jack added first one, then two fingers to his smacking wet pussy. With his other hand, he massaged his clit, fingers stroking hard against it. He pushed and moaned, each shiver forcing his body a few hundred feet in every direction, and by the time he was almost ready to orgasm, the crown of his head brushed the mountains' foothills.

Jack redoubled his efforts, more turned on by how massive he was getting than the actual sexual stimulation, hooking his fingers so they pushed his g-spot over and over. Spasms racked his body, an earthquake shaking the area for hundreds of miles around him, and he finally came as his head peaked into the valley between two large mountains.

He grew yet more as he came, and fame, and came, one orgasm turning into two, then three, then five. His voice was almost too deep for human ears to register, large enough to pick up from halfway across the country. Jack bucked his hips in the air as if fucking an invisible toy far above the clouds, which even his diamond-hard nipples breached. The mountains reduced to rubble under his widening back, and his hips stretched from one edge of the state to the other. His feet dipped into the ocean, sending out massive tidal waves across the whole world. Jack arched his hips up one last time and sprayed into the sea, connecting the string of lakes his cum had made into a river that lead out to the ocean.

Breathing heavily, Jack withdrew his hands and rested them by the ridiculous width of his waist. He was thoroughly spent, having experienced not only the greatest orgasm of his life, but probably the entire top one thousand best orgasms in the universe. Being the size of a state unto himself kept him excited, but he was too exhausted to keep masturbating. His breaths evened out and his eyes shut.

Just at the edge of sleep, Jack heard a voice. "My, you've been a truly naughty boy, haven't you~?" He opened his eyes to tan feet as large as his head behind him. "Hmf. It looks like you'll need some help bringing the rest of the planet to ruin." A thick, long shadow loomed over his chest and released sparkling droplets of pre on him. A cock large enough to split him in half stood proud over his face.

Exhausted as he was, Jack smiled. The fun was only just beginning.

"And... ta-da!" Leon said, briefly tapping the sides of Harry's hips before stepping back.

"Nice magic trick, babe, but what does it...?" Harry trailed off as warmth suffused his body, sprouting from where Leon had touched him. He yelped at the sudden spike in arousal and cupped his half-hard dick. The feeling turned him on so quickly that his jeans were already starting to feel cramped.

Scratch that--it wasn't his erection. The jeans curved over Harry's legs, tight against the thickest point of his admittedly scrawny thighs. They were no longer long enough to cover the tops of his feet. The jeans pinched at Harry's groin, showing off a lewd bulge between his legs.

"You shrunk my jeans?" Harry looked up, unimpressed, but started when he had to look down to meet his boyfriend's eyes. His usually slightly-taller boyfriend.

"You're a smart boy," Leon said coolly, in that mysterious-but-alluring tone he knew would get Harry fully hard. "I think you can figure it out."

It worked, and as his arousal grew, so did Harry. His cock was hard enough to strain at the denim, its head inching down his inseam and beginning to brush the rough fabric. "Oh god," Harry said, but it was more like a moan. Despite himself, he rubbed his palm against the head of his cock, and wasn't rewarded with a sudden spurt in length.

Harry was already nearing seven feet in height, but his cock had to be at least a foot long, growing faster than the rest of his still-proportional body.

Or not-so-proportional body. Harry's legs weren't half as scrawny as they'd been, and pressing a hand against the extraordinarily tight denim told him that almost none of it was muscle. A strange grinding sensation filled the space between his hips as he felt them stretch out and expand. They would have grown anyway, of course--but Harry was becoming more and more pear-shaped by the second.

And more and more gigantic, as well. In the time it took him to notice his hips' increasing width, he'd gained more than another foot. His head was half a foot away from the ceiling--make that less than half a foot. His ankles were exposed, his socks disintegrating against his large feet. He grunted as a slow tearing began at the ass seam of his jeans. Harry's briefs were a little more forgiving, but even they were starting to reach their limits. His balls hung between his legs, both too large for his underwear to contain. Moving denim played against them as well as his foot-and-a-half-long dick as he continued to expand against it.

Harry had more than outgrown his thin shirt by then, but it was hardly giving a fight. The combined pull of his wider shoulders and increased width of his neck tore a large hole where the collar had once been. The arms were basically shredded, and the seams down his sides were separating more and more. Harry's shirt didn't reach more than two inches above his belly button--not quite because of his height, but because of his hips. Each of his ass cheeks had to be approaching the size of his head.

The waistband of his jeans gave up its fight as he surpassed eight feet in height and two feet in length. A slow but deliberate tear worked its way down the outer seams of his jeans. His calves, even as skinny as they were, were overwhelming the legs of the pants. Not to mention his thighs--Harry's thighs were thicker than he imagined was even possible. Each one was as thick around now as both had been before, even adjusted for proportion given his greater height. They grew thicker yet, shoving his cock up against the rough denim seam.

Harry moaned as his cock made further headway toward his left knee, pressing a hand against it in disbelief. Enough pre trickled out to leave a large, wet stain on the outside of his jeans. Harry rubbed his hand up and down its length as the splitting seams exposed it to the cold air.

His head hit the ceiling just as his shirt ripped down the middle and fluttered to the floor as a useless scrap of fabric. Harry's jeans were worryingly tight, the frayed legs halfway up his knees.

"Oh, god, Leon," he moaned. "How big is this gonna make me?"

"As big as you'll let it."

"Fuck you," Harry breathed to Leon's smirk.

He bent forward at the neck, then the shoulders, as more and more of his body insisted upon pressing up against the ceiling. Blindly, Harry navigated backwards until his ass hit a wall. He accidentally hip-checked a tall tower of DVDs, making it crash to the floor. The poor thing wasn't done being tortured, though, as it was decimated completely by half of Harry's monstrously huge ass as the giant of a man sat down.

Sitting was the last straw for his jeans, which roared as they split into two pieces of stretched out denim. Harry picked the remains of his underwear from between his legs as he spread them out. As it was, he was taking up almost half the room. One of his feet pushed the couch into the wall, crushing its frame as his legs continued to lengthen.

Harry's dick was almost gushing pre as it rose up, a three-foot monstrosity between his immense legs. His hips started to press into the walls adjacent to the corner in which Harry sat. He rubbed his hands up and down the cushiony expanse of his thighs as they continued to consume floor space.

"I wonder how much longer this will last," Leon commented. "None of my other partners ever got quite this big."

"Leon," Harry groaned, trying to grab his shaft but finding it too thick to hold with just one hand, even if the hand was the size of a serving plate. His hips dug trenches in the walls and his thighs took up more than half the floor. Between them, each of his balls was the size of a beanbag chair. "Stop," he added, breathless, as his foot knocked over a standing lamp in the corner from furthest from him.

"Stop what?" Leon asked with a coy smile. "Stop comparing your size to my past partners? Because, believe me, you're already more than twice as big as any of them got." Harry moaned loudly enough to shake the windows as a sudden spurt of growth sent him up the wall. He was officially taller sitting down than Leon was standing up.

Harry grabbed as much as he could of his cock, holding it more like a firehose than a penis, as it throbbed and produced more and more pre. It was already up to Leon's ankles. The head was as tall as Leon's knee, and he affectionately patted it as one would a dog.

Between this and Harry's head bumping against the ceiling for a second time, the stimulus overwhelmed him. In one last huge spurt of growth--which bent his legs toward the ceiling as his feet pressed against the walls and forced him to lean forward as his shoulder blades left indents in the ceiling--Harry came, actually flooding the living room floor. His moan made the windows shatter against his huge right thigh. He kept coming, insensate, for at least a minute before he snapped out of it.

His hips were almost as wide as the room, and his legs much longer. If he pushed his feet out any farther, they would leave holes the size of small doorways into the adjacent rooms. Plaster and ceiling popcorn liberally dusted his hair as he attempted to find a more comfortable position for his half-bent torso. Harry was absolutely huge, even discounting his enormous cock and ridiculous thighs, hips, and ass.

Harry looked around himself as best he could, but he couldn't spot Leon anywhere in the sea of cum covering the living room floor. He shimmied down the wall as best he could, raising his legs to make sure he hadn't accidentally crushed Leon. He would have looked under his dick, but it was too thick and heavy for him to move just yet. "Okay, Leon, you can shrink me down," he called, hoping Leon could hear him.

With a light weight, Leon was suddenly there, straddling Harry's cock. But Leon was already out of his jeans, sporting a cock half the size of Harry's, and looking up at the crouched-over giant with excited eyes. It was going to be a long weekend in more ways than one.

Look, an actual thing posted! It's a MIRABLE. It's my usual kind of thing so if you're not into macro growth, guys getting big, guys getting stuck in houses, guys getting curvy, pear expansion (butt/hips/thighs), some gay shit, etc. then you should probably sit this one out. It's like 1,400 words or so long so it's a shortie. But hey, I'm actually writing again, I'm actually writing things I want to share (with strangers) again (this isn't the only thing I've been writing with intent to share, I'm rewriting my Very Incredibly Specific AU fanfic from a few years ago).
