The afternoon sun beat down on the driveway of their suburban home in Sheboygan as Dan’s wife, Sarah, stepped out onto the porch with a mischievous grin. “Babe, the SUV is filthy from that mud run last weekend. Think you could handle washing it before I head to my book club?”

Dan, lounging in the garage with a cold beer in hand, felt a familiar spark of excitement. He’d been tinkering with his latest invention—a sleek, handheld size changer he’d prototyped in secret. It looked like a fancy remote, but it could alter heights with pinpoint precision. His three buddies—Mike, Jake, and Tyler—were already over for what they thought was just a casual hangout and car wash. Perfect.

“On it, honey,” Dan called back, winking at Sarah as she blew him a kiss and disappeared inside. He turned to his friends, all average-sized guys in their thirties, lounging around with sponges and buckets. “Change of plans, boys. We’re making this interesting.”

Before they could protest, Dan raised the device. A soft hum filled the air.

First, he pointed it at himself. Energy pulsed through his body, bones lengthening, muscles expanding. He shot upward—six feet, seven, eight. His clothes stretched and tore slightly at the seams as he towered over the garage, now an imposing 8-foot giant with broad shoulders and powerful arms. The world looked smaller, toys in his grasp.

His buddies stared up in shock.

“What the—Dan?!” Mike yelped.

Dan grinned down at them, his voice deeper, more commanding. “Relax. My turn to have some fun. You three are helping with the wash… but smaller.”

He aimed the device again. One by one, the men shrank. Mike dwindled first, dropping from 5’10” to about 4’2”, his clothes sagging comically. Jake followed, shrinking to a compact 4’1”, looking like a surprised action figure. Tyler was last, ending up at 4’3”, staring at his now-massive hands in disbelief.

“Jesus, Dan! This isn’t funny!” Jake squeaked, his voice higher-pitched but still adult.

“Oh, it’s hilarious,” Dan rumbled, his laugh booming. “And hot. Sarah’s SUV won’t wash itself. Get to work, little men.”

The shrunken trio grumbled but couldn’t deny the strange thrill. Dan’s new height made him feel godlike—every movement deliberate and powerful. He grabbed the garden hose with one enormous hand, the spray nozzle looking like a toy. “Start with the soap. I’ll rinse.”

Sarah peeked out the window, her eyes widening at the sight, but instead of alarm, a flush crept up her cheeks. She knew about the device. She’d encouraged Dan’s “experiments.” Now, watching her giant husband direct his tiny buddies, she bit her lip and stayed hidden, enjoying the show.

The buddies climbed up the SUV like it was a small mountain. Mike scrambled onto the hood, his 4-foot frame barely reaching the windshield wipers. He lathered soap with a sponge the size of a pillow to him, his muscles straining as he worked the suds in circles. The soapy water made his shirt cling to his compact, athletic build, outlining every ridge.

Jake attacked the side panels, standing on his tiptoes and stretching, his smaller body brushing against the glossy paint. Tyler took the wheels, wedging himself between the massive tires, scrubbing vigorously. Their shrunken sizes made every task an erotic challenge—the way their bodies pressed and slid against the wet metal, suds dripping down their arms and chests, turning their clothes semi-transparent.

Dan loomed over them all, his 8-foot frame casting a long shadow. He hosed them down playfully, the warm spray soaking them thoroughly. Water cascaded over Mike’s back as he bent over the roof, his ass flexing under soaked shorts. “Harder, Mike. Get in those crevices.”

Mike shot him a glare that quickly turned heated as Dan’s massive hand reached down, casually adjusting one of the tiny men’s positions—his fingers wrapping around Jake’s waist like he weighed nothing, lifting him higher to reach the sunroof. The casual dominance sent a jolt through all of them. Jake’s breath hitched, feeling the heat of Dan’s palm through his wet clothes.

“Fuck, this is weird… but don’t stop,” Jake muttered, his voice husky now.

Tyler, down by the tires, found himself eye-level with the undercarriage, but his gaze kept drifting upward to Dan’s powerful legs—tree-trunk thighs straining his shorts. The giant’s bulge was impossible to ignore at this scale, heavy and prominent, shifting with every step.

Sarah finally stepped outside, pretending nonchalance at first, but her nipples were visibly hard under her thin tank top. “Looking good, boys,” she purred, leaning against the doorframe. “Dan, you’re such a tease.”

Dan chuckled, the sound vibrating through the air. He set the hose aside and scooped up all three tiny men in one armful, their bodies piling against his broad chest like living dolls. They squirmed, wet and soapy, their hands instinctively gripping his massive pecs for balance. The contact was electric—small fingers exploring the hard contours of his body, the contrast in size making everything feel intensely intimate.

“Time for the final rinse,” Dan announced, but his tone had dropped into something darker, more aroused. He carried them to the side of the SUV, pressing their slick bodies against the warm, soapy metal while he hosed them off personally. The water sluiced over them, over him, soaking everyone. Mike’s face ended up pressed against Dan’s abs, feeling the ridges through the wet fabric. Jake’s hands slid lower, brushing the waistband of Dan’s shorts by accident—or not.

Tyler groaned softly as Dan’s free hand cupped his ass, lifting him effortlessly to scrub a stubborn spot on the roof. “You’re enjoying this too much, big guy.”

“Guilty,” Dan growled, his own arousal growing obvious, the massive outline in his shorts tenting prominently. He lowered the trio back to the ground, but kept them close, his giant form surrounding them. The buddies, drenched and breathing hard, looked up at him with a mix of defiance and desire. Their own cocks strained against their shrunken shorts, the size difference amplifying every sensation.

Sarah sauntered over, running her hand up Dan’s thigh—her fingers barely spanning the muscle. “My hero. The car looks… almost done. But I think you boys need a proper cleanup now.”

Dan’s eyes met hers, then flicked down to his tiny friends. “Garage. Now. All of you.”

The group moved inside, the air thick with anticipation. The SUV sat gleaming under the sun, forgotten for the moment. Inside the garage, Dan shrank himself down just enough to fit comfortably—still towering at 7 feet—while keeping his buddies small. He stripped off his soaked shirt, revealing his chiseled, oversized physique. The three little men followed suit, their compact bodies glistening, cocks hard and eager.

What followed was a tangle of sizes and sensations. Dan lay back on a large workbench, pulling Sarah onto his lap first. She rode him slowly, moaning as his enhanced size filled her completely. Meanwhile, the shrunken buddies swarmed him—Mike and Jake licking and stroking wherever they could reach, their small tongues and hands teasing his nipples, his balls, the base of his shaft as Sarah bounced. Tyler climbed higher, kissing Dan’s neck, grinding his own small erection against the giant’s abs.

Hands roamed. Mouths explored. The contrasts—giant cock sliding into wife, tiny bodies worshiping every inch—pushed everyone over the edge. Orgasms ripped through them in waves: Sarah crying out first, clenching around Dan; the buddies spilling onto his skin; Dan roaring as he came deep inside her, his massive body shuddering.

Afterward, they collapsed in a sweaty, satisfied heap. Dan restored everyone to normal sizes with a lazy flick of the device, though the memories lingered.

Sarah kissed him deeply. “Best car wash ever. Next time… maybe the truck?”

Dan grinned, already plotting. “Deal.”

The buddies just laughed, flushed and hooked. “We’re in.”

Theme Song: Just My Type by The Vamps

Bound by Size: The Giant and His Mini

Josh and Troy had been best friends since their freshman year at the local university. Josh, 6’1” with sandy-blond hair, a square jaw, and an easy, confident grin, had always been the bigger of the two—broad-shouldered, naturally strong, the kind of guy who turned heads in the campus gym without even trying. Troy, 5’10” with dark hair, sharp features, and a mischievous spark in his eyes, was leaner but fiercely determined, the one who dragged Josh through extra sets when motivation lagged. They bonded instantly over iron and protein shakes, spotting each other through grueling workouts, sharing late-night talks about their shared dream: one full year of total dedication to packing on as much muscle as humanly possible, then stepping onstage together in amateur bodybuilding competitions.

“We’ve got the drive,” Troy said one night, sweat still glistening on their chests after a brutal chest-and-back session in their cramped apartment gym. “But we need an edge. Something to fast-track this.”

That edge came in the form of a flyer pinned to the campus bulletin board: an experimental clinical trial at the university’s physiology lab. “Rapid Hypertrophy Peptide Serum”—a new injectable compound designed to supercharge muscle protein synthesis, promising gains that normally took years in mere months. Volunteers were needed, with full medical monitoring. Minimal side effects reported in early testing. Josh and Troy looked at each other, grinned, and signed the waivers the next day.

The results hit like a freight train. From the very first weekly injection, their bodies responded with shocking speed. Within two weeks, shirts that once fit loosely now stretched tight across swelling pecs and delts. By the end of month one, both had packed on twenty-five pounds of dense, striated muscle. Josh’s arms ballooned past 19 inches cold; Troy’s abs carved themselves into a deep eight-pack that looked photoshopped. Their workouts became almost orgasmic—the pumps so intense they’d flex in the locker room mirror afterward, veins popping like rivers across oiled skin, laughing and shoving each other while their cocks strained half-hard against their shorts from the testosterone flood.

Month two cranked it higher. They were both pushing 250+ pounds of pure muscle. Josh hit 6’2” and 280, his back a wide, sweeping V that made doorways feel narrow. Troy, still compact at 5’10” but now 225 pounds of shredded perfection, matched him in density. They outgrew every piece of clothing; seams ripped mid-set. Evenings turned into ritualistic admiration sessions. They’d oil each other up in the living room, hands sliding over hot, hard muscle, tracing striations and peaks. “Fuck, bro, feel this,” Troy would murmur, squeezing Josh’s thickening quad. Josh’s hands would linger on Troy’s carved obliques, the air thick with musk and unspoken heat. They jerked off side by side more than once after sessions—“just bros blowing off steam”—but their eyes locked longer each time, breaths syncing as they came.

By the start of month three, they looked like pros already. But something was… off.

It began during their weekly measurements. Josh’s pants were suddenly riding high on his ankles. “Dude, you’re taller,” Troy said, tape measure in hand. Josh had gained nearly three inches overnight. Troy, meanwhile, found his favorite gym shorts slipping down his hips, his shoes feeling loose. “And you’re… shrinking?” They laughed it off as measurement error or posture, but the changes accelerated fast.

Back at the lab, the doctors ran scans and looked alarmed. The serum had interacted unpredictably with their genetics. In Josh, it triggered a gigantism-like cascade: explosive vertical growth alongside even more extreme muscle hyperplasia. In Troy, the opposite—a rare proportional compression of skeletal structure and soft tissue, condensing his frame while preserving (and somehow densifying) every ounce of muscle. “It appears irreversible,” the lead researcher said gravely. “We’re terminating your participation immediately, but the effects will continue for a few more weeks as the compound clears.”

Josh and Troy sat in stunned silence on the drive home. Panic flickered—bodybuilding dreams, normal life, everything upended. But as the days passed and the changes locked in, something shifted between them. Josh stabilized at a towering 7’0”, 350+ pounds of colossal, vascular muscle. His thighs were thicker than most men’s waists, his pecs heavy slabs that jutted out like armor plates, arms peaking over 28 inches cold, hands big enough to cradle Troy’s entire torso. His voice dropped to a deep, rumbling bass that vibrated through the floor. Troy, meanwhile, dwindled steadily until he stood exactly 2 feet tall—a perfectly proportioned miniature bodybuilder, every muscle still ripped and dense, abs etched like a tiny washboard, biceps popping when he flexed, cock and balls proportionally impressive but now doll-sized.

The apartment became their sanctuary. Josh had to duck through every doorway, reinforced the furniture, and bought a custom king-plus bed that barely contained him. Troy’s world was now a landscape of giants: counters became cliffs, the couch a mountain range. But Josh adapted instantly, scooping his best friend up in one massive palm or letting him ride on his broad shoulder like a living accessory. “My little spotter,” Josh teased affectionately, his huge fingers gently adjusting Troy’s tiny tank top. Troy, never one to lose his fire, fired back: “Still the brains, big guy. Don’t drop me or I’ll kick your giant nuts.”

Practical life flipped. Josh quit his part-time retail job—his size made everything awkward—but started picking up strongman gigs and modeling work for niche fitness brands. Public stares were constant; people gawked, whispered, asked for photos. Troy, tucked safely in a custom harness inside Josh’s hoodie or perched on his shoulder, became the secret weapon—whispering form cues during lifts. Troy’s independence was gone, but he discovered a strange freedom: no more pressure to “be big enough.” Josh handled the heavy lifting (literally), while Troy’s sharp mind kept them organized, scheduling, planning content.

But the real transformation was inside their home—and between them.

The size difference ignited a raw, insatiable hunger they’d only hinted at before. One humid evening, after Josh had carried Troy through a sunset park walk (Troy nestled warm against his massive chest), they collapsed onto the oversized couch in the living room. Josh sprawled back in nothing but loose blue shorts that strained obscenely over his tree-trunk quads and the heavy bulge between them. Troy, shirtless in matching tiny blue shorts that hugged his miniature glutes and thighs, climbed up onto his friend’s lap—exactly as they’d later capture in their favorite private photo.

“Flex for me, big guy,” Troy breathed, eyes wide with lust as he stood on the warm, solid expanse of Josh’s thigh.

Josh grinned, that familiar cocky smile now framed by a jawline that could crush walnuts. He raised both arms into a massive double biceps pose. The peaks erupted like mountains—veins thick as ropes, skin stretched tight over striated perfection. Troy’s small but powerful hands couldn’t even span half the swell. He moaned openly, pressing his entire compact body against one bicep, grinding his tiny, rock-hard cock against the hot muscle while his face nuzzled into the peak. “Jesus… you’re a fucking god now,” he whispered, licking the salty skin, biting gently at the vein.

Josh’s breath hitched, his own enormous cock—now over a foot long and as thick as Troy’s forearm—stirring and thickening rapidly in his shorts, the head already peeking above the waistband like a blunt club. “And you’re perfect, little man. Every inch of you.” One of Josh’s huge hands came down, fingers thicker than Troy’s arms, gently cupping the smaller man’s back and ass, pressing him flush against the bicep. Troy humped harder, his whole torso sliding over the muscle, leaving a wet trail of pre-cum.

They kissed then—deep, hungry, Josh’s full lips enveloping Troy’s as he lifted him effortlessly toward his face. Troy’s hands roamed Josh’s neck and traps, then down to those massive pecs, sucking and biting at nipples the size of quarters while Josh’s free hand roamed lower, tugging Troy’s shorts off with careful precision.

Their sex became an art form of size and worship. Troy explored Josh’s body like a climber scaling a living mountain—crawling across the deep valleys of his abs, licking sweat from every ridge, burying his face between the heavy pecs until Josh’s moans shook the couch. Josh would lay back, shorts discarded, his colossal cock rising like a veiny pillar. Troy straddled it eagerly, wrapping his arms and legs around the shaft as best he could, rubbing his entire muscular little body along its throbbing length while Josh stroked himself slowly, the motion sliding Troy up and down like a living sleeve. Troy’s cock dragged against the hot skin, driving him wild.

“Fuck… use me,” Troy gasped, and Josh did—gently at first, then with growing confidence. He’d coat his palm in lube and slide Troy along his cock in long, full-body strokes, or position the tiny man between his pecs and thrust slowly, the friction and pressure making them both groan. For Troy’s pleasure, Josh was endlessly creative: his massive tongue lapping over Troy’s entire torso and groin in wet, hot strokes that made the smaller man shudder and cum within seconds; or a single thick finger, slicked and careful, teasing into Troy’s tight ass while Josh sucked gently on his tiny cock and balls at the same time.

Orgasms were explosive. Josh’s loads came in thick, ropey torrents—enough to cover Troy head to toe in hot, sticky cum that the smaller man would rub into his own skin like the world’s most expensive lotion, glistening and spent. Troy’s climaxes were smaller but no less intense, his whole body convulsing as he painted Josh’s abs or cock with his release.

Nights blurred into tender aftercare. Troy would curl up asleep between Josh’s pecs or nestled in the crook of one massive arm, the giant’s heartbeat a soothing drum. “I used to worry about being big enough for you—for anyone,” Troy confessed one night, voice soft against Josh’s skin. “Now… this feels right. Like we were always meant to fit together this way.”

Josh’s huge hand stroked down Troy’s back with impossible gentleness. “You’re my everything, little bro. Always were. The serum just made it obvious. I love carrying you. Protecting you. Feeling you worship me like this. We’re closer than any competition could ever make us.”

Publicly, they leaned into their new reality. Josh dominated local strongman events and oversized bodybuilding showcases, drawing crowds who cheered the 7-foot freak of nature. Troy perched proudly on his shoulder or lap during photos, flexing his own miniature physique, becoming an online sensation in size-contrast fitness content. Their bodybuilding dream evolved—they created a joint brand, “Giant & Mini,” with training videos, sponsorships, and private subscriber sessions that got very explicit. The money let them renovate: reinforced everything, custom everything, a life built around their sizes.

Months later, they recreated that perfect living-room moment on the couch for a private “photo shoot” that quickly turned filthy. Josh lounged back, blue shorts barely containing him, one arm flexed in a towering double biceps, the other supporting Troy who sat on his massive thigh, also shirtless and flexing, looking up at his giant lover with pure adoration and lust. Troy’s small hands traced Josh’s abs as the giant’s free hand slid down to cup his ass.

“Ready for round two, big guy?” Troy grinned, already grinding against the growing bulge beneath him.

Josh’s deep laugh filled the room. “Always, little man. Climb on up. We’ve got all night.”

The kitchen light cast a warm glow over the two friends as they stood in Jim’s apartment, the air thick with the faint scent of protein powder and something electric—something neither could quite name yet. Jim, at 5’10” and carrying a hefty, soft build that spoke of comfort and indulgence, leaned against the counter with his shirt riding up over the curve of his substantial gut. Steve, shorter at 5’6” and carrying a little extra padding himself, couldn’t stop stealing glances upward. He’d always loved the way Jim towered just enough to make him feel small, loved the way that heavy belly strained against Jim’s shirts after a big meal. But tonight, Steve had a secret.

“Drink it,” Steve said, pushing the oversized shaker toward Jim. His voice was steady, but his hands trembled with anticipation. “It’s… special. I mixed in something I’ve been working on.”

Jim raised an eyebrow, his thick beard twitching with a skeptical laugh. “You’re fucking with me, right? Some weird supplement that’s gonna make me huge overnight?” He patted his belly, the soft flesh jiggling under his palm. “I’m already big enough, man.”

Steve’s eyes darkened with hunger. “You’re perfect. But I want you bigger. I’ve wanted it for years.” He stepped closer, tilting his head back to meet Jim’s gaze. “I’m gay, Jim. And I’m into… this. Big bears. You. I’ve been obsessed with watching you grow that gut. And I found a way to help it happen.”

Jim stared, stunned. He’d had no idea. Steve had always been the quiet, supportive friend—spotting him at the gym, cooking massive meals together, teasing him about his appetite. But this? The confession hung heavy between them. Jim’s cock twitched unexpectedly in his shorts at the raw honesty in Steve’s eyes.

“You’re serious,” Jim muttered, then shrugged with a grin. “Fuck it. If it works, I’m game. I’ve always liked being… substantial.”

Steve watched with wide eyes as Jim downed the shake. The change started slow—a warm flush spreading through Jim’s body, then a sudden surge. Jim gasped, gripping the counter as his bones lengthened with audible creaks. His shoulders broadened, his chest barreled out, and that already impressive gut ballooned forward, rounder and heavier. Inch after inch stacked on. Steve felt it too—a dizzying pull, like his own mass was draining away. He shrank, clothes loosening, the world growing taller around him.

When it stopped, Jim stood at a towering 7’4”, his body a massive, powerful bear of a man. His black shorts clung desperately to tree-trunk thighs, the waistband digging into the vast, overhanging shelf of his belly. Steve, now barely 4’0”, stared up in awe, his head level with the bottom of Jim’s enormous gut.

“Holy shit,” Jim rumbled, his deep voice vibrating through the room. He looked down at his hands—huge now—and then at Steve, a mix of shock and delight spreading across his bearded face. “You… you actually did it. Look at you, little guy.”

Steve’s heart hammered. The height difference was intoxicating. Jim’s belly loomed over him like a warm, soft wall. Without hesitation, Steve stepped forward, his small hands grabbing the hem of Jim’s shorts and yanking them down. Jim’s thick, fat cock sprang free—semi-hard already, easily as long as Steve’s forearm and girthy enough to make the smaller man’s mouth water.

“Steve, what the—oh fuck,” Jim groaned as Steve wrapped both hands around the base and lifted the heavy shaft toward his face. Steve stood on tiptoes, then pressed his lips to the plump head, kissing it reverently before opening wide. He had to stretch his jaw to take it, but he did, sucking greedily on the first few inches while stroking the rest with eager hands. Jim’s cock swelled fully in his mouth, veins pulsing against Steve’s tongue.

Jim’s massive hand settled gently on the back of Steve’s head, not forcing, just guiding. “That’s it… good boy. You’ve been wanting this, huh?” His belly rested heavily on Steve’s shoulders and the top of his head as he leaned forward slightly, feeding more of his fat dick into the eager mouth. Steve moaned around the girth, saliva dripping down his chin, eyes watering with effort and lust. He bobbed as best he could, worshipping every inch, his own smaller cock tenting his shorts painfully.

The sight was obscene and perfect: the towering giant being serviced by his shrunken friend right there in the kitchen. Jim’s balls, heavy and full, swayed against Steve’s chest with every suck.

After several long, sloppy minutes, Jim pulled back with a wet pop, his cock glistening. “Couch. Now.”

He lumbered to the living room, the floor creaking under his new weight, and dropped onto the wide sofa. His belly spilled forward between his spread thighs, a massive, soft dome that rose and fell with his breathing. Steve approached, stripping off his own clothes, his smaller but still eager dick bobbing free—now perfectly proportioned for what he had in mind.

“Can I… fuck your belly button?” Steve asked, voice husky with need. He climbed up onto Jim’s lap, straddling the lower part of that enormous gut. Jim chuckled, the sound a low rumble, and leaned back, lifting his belly slightly with both hands to expose the deep, inviting navel.

“Fuck yes. Use me, little man.”

Steve pressed the head of his cock against the soft, warm indent. It slid in easily—Jim’s belly button was deep and accommodating now, like a tight, fleshy sleeve. Steve groaned loudly as he pushed inside, the heat and give of Jim’s fat surrounding him. He thrust shallowly at first, then harder, hips slapping against the yielding belly flesh. Jim moaned, the sensation strange but intensely pleasurable, his own massive cock twitching and leaking precum onto his gut.

“That’s so fucking weird… and hot,” Jim growled, watching the tiny Steve hump his navel like it was the best pussy he’d ever had. Steve’s hands sank into the soft overhang of Jim’s belly for leverage, kneading the warm fat as he fucked faster, lost in the fantasy.

After a few minutes of desperate thrusting, Steve pulled out, panting. “Need more. Need you inside me.”

Jim’s eyes gleamed with dominant hunger. He lifted Steve effortlessly with one huge hand, positioning the smaller man over his throbbing erection. “You sure you can take it, shortstack?”

Steve nodded frantically. “Please.”

Jim lowered him slowly. The fat head of his cock pressed against Steve’s tight hole, stretching him open inch by inch. Steve cried out in pleasure-pain as he was impaled, his body sliding down the thick shaft until he was nearly halfway seated, belly bulging visibly from the intrusion. Jim’s gut pressed warmly against Steve’s chest and face, smothering him in soft, heavy flesh.

“Fuck, you’re tight,” Jim grunted. He began to pump, strong hips thrusting upward, bouncing the tiny man on his cock like a living toy. Steve’s legs dangled, feet kicking helplessly in the air as he was fucked senseless. Each powerful stroke made his own smaller dick slap against Jim’s belly, precum smearing across the vast expanse.

Jim fed him more—holding Steve down deeper, grinding that massive gut against him, letting the weight pin him in place while the huge cock rearranged his insides. The room filled with the sounds of skin slapping, wet squelching, and their mingled moans.

Steve came first, shooting ropes of cum across Jim’s belly, the sight pushing the giant over the edge. Jim roared, flooding Steve’s insides with thick, hot loads that overflowed and dripped down.

They stayed like that for a long while afterward—Steve draped limply over Jim’s heaving gut, still impaled, while Jim stroked his back with one enormous hand.

“I could get used to this,” Jim murmured, a satisfied smile on his face as he looked down at his shrunken, cum-drunk friend.

Tara had always been the target of the school’s cruelty. At barely 5’2”, with her pale skin, jet-black hair cascading down her back, and an impossibly full, heavy pair of DD breasts that strained against every top she wore, she was impossible to ignore. The jocks and cheerleaders called her “Witch Tits” or “Goth Goblin,” whispering that her dark eyeliner and pentagram choker meant she was casting spells in the girls’ bathroom. But none of them knew how right they were.

For months, Tara had pored over her grandmother’s old grimoire, perfecting one spell above all: Amplificatio Corporis. A ritual of raw, forbidden power that would let her grow—truly grow—into something unstoppable. And this year’s Halloween party at the old frat house was the perfect stage. Jake would be there. Jake, the 6’4” star quarterback with the chiseled jaw, broad shoulders, and that cocky grin that made her thighs clench every time he passed her in the hall. She’d fantasized about him for years. Tonight, she would make him hers.

She arrived at the party in full witch regalia: a tight crimson-and-black corset that pushed her massive tits up into two creamy, jiggling pillows of cleavage, a short ruffled skirt, thigh-high fishnet stockings that dug deliciously into her soft flesh, and shiny black platform boots. Her tongue piercing glinted as she smiled at the stares. The house was packed—orange lights, fake cobwebs, thumping bass, and costumed idiots already half-drunk.

Tara slipped into a dimly lit corner, whispered the incantation, and felt the magic ignite in her veins like liquid fire. Heat bloomed in her core, spreading outward. Her body shuddered as the first wave hit.

“Oh… fuck…” she moaned under her breath.

She shot upward fast. Five-foot-two became six feet in seconds, her curves swelling proportionally—her breasts ballooning heavier, rounder, straining the corset until the laces creaked. Seven feet. Eight. Her thick thighs thickened further, the fishnets stretching taut over expanding muscle and plush softness. Ten feet. Twelve. The ceiling rushed closer as she hit fifteen feet tall, her head brushing the rafters, black hair tumbling like a dark waterfall around her shoulders. Her ass and hips had widened into powerful, womanly proportions that made the wooden floor groan beneath her massive boots.

The party erupted in screams.

People scattered as Tara rose like a living goddess, her enormous tits now each the size of beach balls, heaving with every breath inside the barely-contained corset. Her long legs, wrapped in those stretched fishnets, dominated the room. She grinned, sticking her tongue out playfully—longer now, pierced and wicked—as she raised her arms, palms open, and let out a theatrical witch’s cackle that shook the walls.

“Trick or treat, bitches!” she boomed, her voice deeper, sexier, dripping with power.

Most of the partygoers fled in panic, tripping over furniture. A few stayed frozen, staring up at the giant goth beauty in awe and terror. But Tara’s eyes locked on one person who hadn’t run.

Jake.

He stood in the middle of the room, staring up at her with wide eyes, his muscular body rigid in his tight grey t-shirt and jeans. His cock was already visibly hardening in his pants as he drank in the sight of her: those colossal thighs, the glistening black boots big enough to crush a couch, and especially those massive, jiggling breasts swaying high above him.

Tara licked her lips slowly. “Hey, Jake,” she purred, her voice a sultry rumble that vibrated through his chest. She took one massive step forward, her boot landing with a thud that rattled glasses off tables. Crouching down, she brought her face closer—still towering over him even on her knees. “You’ve ignored little old me for years. Teased me with your friends. But look at me now…”

She reached down with one huge hand, fingers easily wrapping around his waist, and lifted him effortlessly off the ground. Jake gasped as she brought him up to her chest level, his face inches from the deep, warm valley of her cleavage. The scent of her skin—vanilla, smoke, and raw feminine power—flooded his senses.

“You… you’re fucking huge,” he breathed, hands instinctively reaching out to touch the soft, pillowy sides of her breasts. They overflowed his palms completely, warm and impossibly heavy.

“Mmm, you like that?” Tara cooed. She pressed him gently against her left tit, smothering his face and chest in warm, yielding flesh. Jake groaned, his hands sinking in as he kissed and licked the exposed skin above her corset, grinding his rock-hard cock against the underside of her massive breast. Tara moaned, the sound echoing through the now-empty house. She could feel herself getting soaked, her giant pussy aching beneath the ruffled skirt.

With her free hand, she tugged at the hem, hiking it up just enough to reveal the soaked crotch of her black lace panties stretched tight over her enormous mound. She set Jake down carefully between her spread thighs—his head barely reaching the top of her knees even while she was kneeling. The heat radiating from her was intense.

“Everyone else ran away scared,” she whispered, her voice husky. “But you’re not scared, are you, big boy? Get on your knees and worship your giant witch.”

Jake didn’t hesitate. He dropped down, hands gripping her fishnet-covered thighs as best he could—the thick, soft flesh filling his arms. He buried his face against the damp lace, licking and sucking eagerly through the fabric, tasting her arousal. Tara shivered in pleasure, one massive hand gently cradling the back of his head, guiding him as she ground slowly against his mouth. Her fishnets strained and tore slightly at the seams from the pressure.

“Fuuuuck yes… just like that,” she growled. She peeled her panties aside with two fingers, revealing her glistening, puffy pussy lips—each one bigger than his hand. Jake dove in, tongue working her swollen clit while his fingers explored her slick folds. Tara’s hips rocked gently, careful not to crush him, her massive tits bouncing heavily above as she pinched her own nipples through the corset.

The pleasure built fast. Tara’s breath came in deep, rumbling moans. “Jake… I’m gonna come…” She pressed his face tighter against her, thighs trembling around him like warm pillars. Her orgasm crashed over her in powerful waves, her giant pussy gushing wetly against his tongue and chin as she cried out, the sound shaking the rafters.

Panting, she lifted him again, bringing him up to her face. She kissed him deeply—her full lips easily covering most of his face—tasting herself on him. Then she lowered him slowly down her body once more, this time pressing his straining erection against the slick heat of her entrance.

“Be a good toy,” she murmured, “and fuck me.”

Jake thrust forward eagerly, sinking his cock into her enormous, velvet-soft pussy. Even though she was scaled up massively, the fit was tight and perfect for him—her walls hot, slick, and rippling around his shaft. Tara moaned loudly, using one hand to guide his hips as she rocked against him, her other hand squeezing her own breast. The size difference made every motion overwhelming: Jake felt like he was fucking a living goddess, surrounded by warm, yielding flesh and the intoxicating scent of her.

She came again quickly, her inner muscles squeezing him rhythmically until he couldn’t hold back. Jake groaned into her cleavage as he pumped deep inside her, filling her with rope after rope of cum.

Afterward, Tara slowly lowered herself to sit on the floor—careful not to crush anything—still holding Jake against her chest like a treasured toy. She stroked his back with one finger, smiling down at him with half-lidded eyes.

“Next time,” she whispered, kissing the top of his head with her full lips, “I’ll let you explore every inch of me. But for now… you’re mine, jock boy. Your little witch finally got what she wanted.”

Shawn flexed in the mirror of the college gym, his 6’4” frame a sculpted masterpiece of rippling muscle. At 28, he was the star personal trainer on campus—broad shoulders, boulder-like delts, a chest that could bench a small car, and abs carved deep enough to lose fingers in. Veins snaked over his arms like rivers on a map, and his quads strained every pair of shorts he owned. He lived for the pump, the stares, the raw power thrumming through his veins.

When the art department email popped up asking for a “life model with exceptional physique” for a special session, he jumped at it. Show off for a room full of students? Hell yeah. He showed up in loose sweats and a tank that barely contained him, already half-hard at the thought of stripping down and holding poses while eyes traced every inch of him.

The studio was the usual—high ceilings, easels in a semicircle, soft lighting from overhead lamps. But the chalkboard stopped him cold:

LIFE DRAWING: GIANT MODEL

Macro Session – Temporary Growth Protocol

The professor, a sharp-eyed woman in her forties, smiled. “Shawn, right? We use a special compound for these advanced classes. Completely safe, reversible in two hours. You’ll grow to twenty feet. Think you can handle it?”

His cock twitched hard in his sweats. Grow? The fantasy hit him like a freight train—towering, unstoppable, every muscle magnified to godlike proportions. “Fuck yes,” he grinned, already peeling off his tank.

They gave him the injection in his thick glute—cool fire spreading through his veins. Then the students filed in, sketchbooks ready, a mix of wide-eyed undergrads who clearly hadn’t expected the model to be this built even before the growth.

It started slow. A deep, throbbing heat in his core. Shawn stepped onto the low platform, dropping his sweats and wrapping a white sheet low around his hips like a classical statue. His cock was already thickening, half-hard and heavy against his thigh. Then the surge hit.

“Oh… shit,” he groaned, voice dropping deeper as his body expanded. Bones lengthened with wet, powerful cracks. Muscles ballooned outward, fibers splitting and reforming thicker, denser. His chest surged forward, pecs becoming massive slabs that cast shadows over the room. Abs deepened into an armored eight-pack. Arms thickened to the size of tree trunks, biceps peaking like mountains. His legs exploded with size—quads and hamstrings swelling until the sheet strained and tore at the seams, barely clinging to his now enormous, muscular ass and thickening cock.

The students gasped as Shawn shot upward. Ten feet. Fifteen. Twenty. The platform groaned beneath his massive bare feet. His head nearly brushed the high ceiling, and the sheet finally gave way, fluttering down like a surrendered flag. His cock—now a veiny, throbbing monster the size of a grown man’s arm—swung free, heavy and semi-erect, pulsing with every heartbeat. Pre-cum already beaded at the tip, thick as honey.

“Fuuuuck…” Shawn’s voice boomed, low and resonant. He struck the pose from the demonstration photo—right arm flexed high, left extended in a powerful reach, one thick leg forward. Every movement sent ripples across his hypertrophied physique. His traps rose like cliffs beside his neck. Lats flared so wide they blocked light from the windows. The deep cuts of his obliques pointed like arrows toward the base of his colossal dick, which now hung heavily between thighs thicker than the students’ waists.

The class went silent except for the frantic scratch of charcoal. Eyes darted from his boulder-sized calves up the endless columns of his legs, over the ridged landscape of his abs, across the vast expanse of his chest. A few students were flushed, shifting in their seats. One girl in the front row bit her lip so hard Shawn noticed.

“Like what you see?” he rumbled, voice vibrating through the floor. He adjusted his stance, flexing his pecs so they bounced with heavy, powerful weight. His cock twitched visibly, lifting slightly as blood rushed in. Being this huge felt incredible—every nerve ending amplified, the cool studio air kissing his hyper-sensitive skin, the weight of his own muscles pressing down on him like the ultimate pump.

One brave student, a lean guy with a beanie, raised his hand. “Can… can you do a different pose? Something more… dynamic?”

Shawn smirked down at them. At twenty feet, they looked like dolls. He dropped into a side chest pose, turning slightly so the striations across his pecs and the sweep of his delts caught the light. His massive cock swayed with the motion, now fully hard and pointing upward like a weapon, the head glistening. He reached down with one enormous hand and gave it a slow, lazy stroke—fingers barely able to wrap around the girth. A low, erotic groan escaped him, echoing off the walls.

The students drew faster. Some were openly staring now, sketchbooks forgotten for moments at a time. Shawn could smell their arousal mixing with the scent of charcoal and linseed oil. He posed for them—crab most muscular, hitting every angle, letting his body dominate the room. Sweat gleamed across the vast planes of his muscles. His balls hung heavy and full beneath his shaft, churning visibly.

“God, you’re fucking huge,” someone whispered.

Shawn’s cock throbbed at the words. He was leaking steadily now, thick drops falling to the platform with audible plaps. The power rush was intoxicating—being a living colossus, worshipped by dozens of eyes while his body screamed with erotic energy. He flexed his biceps again, watching the peak rise like a volcano, and felt his orgasm building from the sheer intensity of it all.

When the professor finally announced the reversal was coming, Shawn was panting, muscles pumped to their absolute limit, cock still rock-hard and aching. As he slowly shrank back down—muscles deflating but still enormous by normal standards—he caught the hungry looks from the class.

“Same time next week?” he asked, voice husky, wrapping the ruined sheet around his waist again.

The entire room nodded.

The morning light filtered through the half-drawn blinds of their modern apartment, casting a soft glow over the living room where they’d crashed the night before after a late movie marathon. Alex stirred first, his body feeling strangely heavy and the world around him... off. He blinked, rubbing his eyes, and realized he was standing on what felt like a vast, shaggy blue rug the size of a football field. His heart slammed against his ribs as he looked up.

Towering above him, like a living goddess sprawled across the horizon, was his girlfriend, Mia.

She was enormous. At least eighteen feet tall, her lithe, athletic body stretched out lazily on the floor, propped up on one elbow with her long brown hair cascading like a waterfall over her shoulder. She wore the same light gray sports bra and matching boy shorts she’d fallen asleep in—now stretched taut over curves that had scaled up to breathtaking proportions. Her full breasts strained against the fabric, rising and falling with each slow breath, the soft swell of her cleavage deep enough to lose himself in. Her long legs, smooth and toned, extended endlessly across the room, one knee slightly bent, her bare feet dangling near the far wall. A patterned pillow cradled her hip, and her free hand rested possessively on the rug, fingers splayed like they could scoop up a car.

Alex, now barely two feet tall, stood in nothing but his black boxer briefs, staring up at her in stunned awe. The rug’s fibers felt like thick grass under his tiny feet. The couch behind him loomed like a mountain range.

“Mia?” His voice came out high and squeaky, barely a whisper in the vast space.

She stirred, a soft groan escaping her full lips. Her eyes fluttered open—those deep, expressive eyes now the size of dinner plates— and she blinked down at him, confusion flickering across her beautiful face. Then her gaze focused, and her eyebrows shot up.

“Oh my God... Alex?” Her voice was the same warm, slightly husky tone he loved, but amplified, rumbling through the air like distant thunder wrapped in velvet. She shifted, her massive body rolling slightly toward him, the motion sending a subtle tremor through the floor. Her hand lifted from the rug and hovered above him, casting a shadow. “What... what happened to you? You’re so... tiny.”

She sat up a little more, her abs flexing under the thin fabric of her top, and propped herself on both elbows. The movement made her breasts sway heavily, drawing his eyes helplessly. From his perspective, she was a landscape of soft skin and inviting curves. Her nipples, faintly outlined through the sports bra, had hardened slightly in the cool morning air.

Alex’s cock twitched in his briefs, a confusing mix of fear and raw arousal flooding him. “I... I think we both changed. You’re huge, Mia. Like... giantess huge.”

A slow, intrigued smile curved her lips. She bit the lower one gently, her eyes darkening with something hungry as she took in his miniature form. “Giantess, huh?” She chuckled, the sound vibrating through his chest. “And you... my little man. God, you look adorable down there. So helpless.”

She extended one long arm, her fingers—each as thick as his torso—descending slowly toward him. Alex didn’t run. Instead, he stood frozen as her warm fingertips brushed his back, gentle despite their size. The touch was electric. She carefully pinched the back of his briefs between thumb and forefinger, lifting him effortlessly off the rug. He dangled in the air for a moment, legs kicking lightly, before she lowered him onto the warm, smooth expanse of her bare stomach, just below the hem of her sports bra.

The skin there was silky and fever-hot, rising and falling with her breathing. Alex pressed his tiny hands against her, feeling the faint thrum of her pulse. Her scent—familiar vanilla lotion mixed with her natural musk—enveloped him like a cloud.

“Mmm,” Mia purred, her free hand sliding down to rest near him, one finger tracing lazy circles on her own thigh. “This feels... weirdly good. Look at you, baby. So small on me. I could just...”

She trailed off, her breath hitching as she watched him explore. Alex crawled higher, drawn irresistibly toward the deep valley between her breasts. The sports bra hugged them like a second skin, the fabric slightly damp from sleep. He reached the underside of one massive mound and pressed his body against it, his face sinking into the yielding softness. It was like being hugged by warm, living pillows—plush, heavy, and overwhelmingly feminine.

Mia moaned softly, her head tilting back. “Fuck, Alex... I can feel you. Your little hands... they’re teasing me.” Her hand came up, cupping the breast he clung to from the outside, gently pressing him deeper into the cleavage. The pressure was firm but careful, smothering him in her warmth. He could hear her heartbeat thundering around him, feel the subtle jiggle as she shifted.

His erection strained painfully against his briefs now. He rubbed himself against the inner curve of her breast, humping instinctively, the friction driving him wild. Precum soaked the fabric as he ground against her.

“Ohhh, you naughty little thing,” she whispered, voice thick with lust. Her other hand slid down her body, slipping under the waistband of her boy shorts. He could see the outline of her fingers moving slowly between her legs, the fabric tenting as she touched herself. “You’re making me so wet already. My tiny boyfriend, getting off on my tits...”

She lifted him again, this time bringing him up to her face. Her lips parted, glossy and full, and she gave him a slow, deliberate lick—her tongue, warm and wet, dragging from his chest to his face in one long stroke. The sensation was overwhelming, coating him in her saliva.

“Delicious,” she murmured, eyes half-lidded. “Now... let’s see how you feel somewhere else.”

Carefully, she peeled down the front of her sports bra with one hand, exposing one perfect, heavy breast. The nipple was stiff and pink, larger than his head. She lowered him onto it, letting him straddle the sensitive peak. Alex wrapped his arms and legs around it as best he could, sucking and grinding against the firm bud. Mia gasped, her back arching, which lifted him higher into the air.

“Yes... just like that, baby. Worship your giant girlfriend.”

Her fingers returned between her thighs, moving faster now, the wet sounds faintly audible even to his tiny ears. She was breathing harder, her chest heaving beneath him. Alex lost himself in the rhythm—licking, humping, clinging to her nipple like it was his entire world. The power imbalance, her sheer size, the way she could crush him without effort but chose instead to moan and tremble for him... it was intoxicating.

Mia’s free hand eventually scooped him up again, sliding him down her body. She tugged her boy shorts aside, revealing her glistening pussy—smooth, swollen, and towering like a warm, slick cave. The heat radiating from her was intense.

“Be a good little toy for me,” she whispered, her voice husky and commanding.

She positioned him carefully, pressing his tiny body against her clit first. The sensitive nub was engorged and slippery. Alex thrust against it with his whole body, his cock sliding along the slick folds as he hugged and rubbed her. Mia cried out, her thighs quivering on either side of him like warm walls.

He felt her fingers guiding him lower, dipping his lower body into her entrance—just enough for him to feel the tight, velvet heat clenching around his legs. She used him like a living dildo, sliding his body in and out in shallow, controlled strokes while her other hand worked her clit.

The world was nothing but her—her scent, her heat, her moans growing louder and more desperate. “Alex... oh fuck, I’m gonna...”

Her orgasm hit like a storm. Her walls pulsed around him, flooding him with her juices as her body shook. She kept him pressed there through the aftershocks, panting, her giant hand gently stroking his back.

When she finally lifted him, spent and glistening, she brought him to her lips for a soft, affectionate kiss that covered most of his body.

“My perfect little man,” she murmured, smiling down at him with heavy-lidded eyes. “We’re going to have so much fun figuring this out... but first, I think you deserve a reward.”

She laid back fully, placing him between her breasts again, letting them pillow around him like a warm, living bed. As her breathing slowed, one finger idly stroked his tiny, aching cock until he came hard against her skin, shuddering in ecstasy.
