Bros to Dads - Part 1

Commission

The double doors of Delta Pi slammed open with a bang, and Brady swaggered inside, fresh off a two-hour chest and butt session at the gym. Standing tall at 6’4” and weighing about 240 pounds of prime beef, he drew attention without even trying. But every step he took was cocky, almost theatrical, making him the center of attention. He was still slick with sweat, and the collar of his cutoff hoodie stretched thin over the girthy curve of his pecs, clinging in patches to the solid muscle beneath. His shorts hung low on his hips, tight enough to accentuate the thick curve of his thighs and the bouncing roundness of his meaty ass.

“Daddy’s home,” Brady shouted, stretching both arms behind his head to flex his biceps and give the hallway a full view of his deep V-cut waist. The hallway echoed with a few cheers but mostly groans—half the bros were nursing hangovers, the others halfway through preparty beers. Brady didn’t care. He grinned like he owned the place—he kind of did. He was the biggest guy in the frat house and the one leading most of the crazy stuff they did.

He strutted past the main living room, which was already beginning to fill with bodies, giving a couple of bros playful smacks on the back and tossing a protein bar at one bro napping on the couch. “You gonna sleep through Chug Night, Mikey?” Brady barked, flexing over him to tease the young man. “Where’s your spirit, bro? What are you? A 40-year-old dad?”

Brady moved like a superstar on stage. Every motion was exaggerated enough to make people look. Every pause he took was timed to give his muscles the right spotlight. His thick chest bounced with each step, accentuating its size and fullness. His torso tapered into a trim waist, but his ass was colossal. His shorts rode up each time he bent forward, practically cleaved in the middle by the volume of muscle he carried back there.

He was proud of his magnificent physique and never missed a chance to show off before his frat bros or any person he met. He playfully reached for his crotch and gave it a shake to adjust his thick cock and hefty balls, smirking as always when he felt his bulge filling his hand and then some. He was a big guy all over, but his bull balls were one of his favorite assets.

He cut through the kitchen with a loud clap. “Where’s my crew?”

“Over here, Big Ass,” came Tyson’s voice, laughing as he leaned against the fridge, chugging a water bottle like it was beer. He constantly teased Brady about the big butt, partly as a form of respect for the big guy.

Tyson was 6’1” and lean. He was the laid-back MVP of the track team. He had long legs that he loved to show off with too-short shorts. He wore mismatched socks and a half-zipped hoodie over a tank top. He was the type of guy who could make dishevelment look hot. As much as Brady was cocky about his looks, Tyson was a cocky jockster, too confident to mind his words before they came out of his mouth.

“Big Ass, huh? Bro, look at it,” Brady said, turning around and playfully flexing his massive glutes. “Fucking smashed the workout.”

“Dude, you’re reeking confidence today,” Tyson said, grinning. “You knock out the whole gym or just scare off the mirrors?”

“Didn’t even break a sweat ‘til I saw my own reflection.” Brady walked up and flexed both arms. “But anyways, Chug Night! Come on!”

Zander snorted from behind his phone in the corner, tapping out something sarcastic on the group chat. He was shorter than Brady but wide and thick with ex-wrestler mass. He had one of those builds that carried strength like a barrel: thick arms, a thick neck, and a belly that was already more muscle than fat, even in his off-season. His tank top was snug against his thick chest, and the hem barely covered the curve of his core. His shorts left little to the imagination, accentuating his powerful thighs.

“You’re not gonna fit through the door if your ego gets any bigger,” Zander said, not looking up. “Maybe that ass is the result of that ego.”

“That’s the plan, bro,” Brady grinned. “It’s not ego. Just look at me.”

“Brady, focus!” Jamal said, leaning against a wall with a Bluetooth speaker on one shoulder and his shirt already half unbuttoned. “You hitting the liquor store run or what? We’re down to like two sad-ass White Claws and some mystery seltzer.”

Jamal was tall and powerful. His broad chest flexed with every gesture, and his smile was downright dangerous. His joggers clung to his hips in a way that always made heads turn, and he knew it. He was known among the brothers for having the second biggest butt in the frat house—only Brady beat him. He was slightly more serious than the others but playful and childish when needed.

Brady flexed his arms, heading for the door. “Say no more. I’m feelin’ pumped. I’ll do it.”

From the back of the kitchen, Noel raised a cautious hand. “I can go too. You know, so you don’t bring back, like, six bottles of coconut rum again.”

Noel was the smallest of the group at 5’10”, clean-cut and well-built in a quietly impressive way. He was always the helpful one, the one making sure no one chugged on an empty stomach. He wore a Delta Chi shirt tucked into gym shorts. His short dark hair and bright blue eyes gave him a youthful appearance, but his devilish smile betrayed his thoughts.

Brady grabbed his keys and spun them on one finger. “Let’s roll out, bros.”

The group squeezed into Brady’s truck, all five of them crammed in like a protein-packed clown car. The corner store they rolled up to was a faded red box of a building, glowing under a flickering neon sign that just read “DR!NKS.” Inside, the lighting buzzed and the aisles smelled vaguely of popcorn and lemon-scented bleach. They roamed the coolers, unimpressed by the familiar brands.

“No way I’m paying eighteen bucks for Coors,” Zander said.

“Dude, come on! Don’t be so cheap!” Tyson said.

“Bros!” Brady called out from the very back. “Come check this out?”

He pointed to a half-forgotten metal shelf pushed near the loading door, where dust-covered six-packs sat stacked haphazardly. The labels were hand-stamped in bold, retro lettering: “Dadbod.” Each case was marked $1.

Noel picked up a six-pack and gave it a shake. “It looks like a prank.”

“It looks dangerous,” Jamal added.

“It looks like a great deal,” Brady smirked. “It’s a dollar. I say we take every single one.”

Zander nodded, hoisting two cases into his arms. “Either it’s beer, or we drink a lame juice or something. It’s only a dollar, and there’s a lot here. Win-win.”

“If this poisons me or turns me into a freak, I’ll fucking kill you all,” Tyson teased.

“Come on!” Brady said, flexing. “Worst things worse, you get a dad bod,” he said, laughing as they went to pay for all available six-packs of “Dadbod.”

Back at the Frat House, the bros awaited impatiently in the living room. Some guys in tanks and sweatpants leaned on couches or perched on counters. The speakers thumped with bass, and everyone cheered as the five entered with arms full of mysterious beer.

Brady climbed on the coffee table, holding one can high. “Gentlemen! We were lucky! A dollar a case, so we brought a lot! Let’s drink!”

They cracked open the first cans as laughter echoed through the house. The beer was surprisingly smooth—malty, strong, and slightly sweet. Can after can disappeared into the bros’ wide throats. It was chaos. It was frat heaven. Some of the guys only had one and didn’t feel much after they had finished them. But here and there, subtle shifts began: a groan from the couch, or a shirt stretching tighter than it had a moment ago. It was subtle but undeniable.

Zander leaned back, rubbing his stomach. “Damn. Is it just me, or is this stuff heavy?”

Jamal’s hands went to the waistband of his joggers. “I know! Bro, I feel like, dude, I’m so full. Even my pants are tighter. Like, I’m not imagining that, right?”

Brady laughed, patting his slightly rounded abdomen. “Y’all lightweights. Drink more!”

Tyson was sitting cross-legged on the floor, watching his hoodie ride up inch by inch. “I feel...warm. Like, really warm. Fuck, this thing is good,” he said, laughing and drinking more.

Noel tugged at the hem of his shorts, blushing but smiling. “I must admit that this Dadbod thing is awesome,” he said as his inhibitions faded the drunker he got.

All around them, guys were casually adjusting, unbothered, even amused, as their pecs thickened slightly, their balls swelled heavy in their laps, and bellies began to round. Nothing dramatic yet, but something was happening. But no one was stopping.

Brady grabbed another can, slammed it back, and his massive chest rose and fell with every chug. “Keep it coming, bros! The night’s young.”

Burps, moans, creaking couches, and laughter filled the room. Shirts rolled up, pants unbuttoned, and abs gave way to soft curves. But the party didn’t slow down.

The frat house roared louder as the first wave of changes slipped under the radar—tents in shorts, fuller faces, and grunts of surprise that turned into laughs. They had no idea it was only getting started.

As the night wore on, the transformations escalated. The ones who had sipped a single can started changing slowly but undeniably. Garrett, a lean track bro with a runner’s frame, had only taken one can and was now lounging on the couch, absentmindedly rubbing his thickening pecs through his hoodie. They had puffed up subtly, firmer and broader, and his nipples were constantly pressing against the fabric. His ass was once barely there and now was plumped out roundly against the cushions as his track pants clung tighter with each passing minute. He was too buzzed to realize anything was off, laughing and chatting with whoever passed by.

Caleb, who had finished a whole can, was starting to shift more dramatically. His thighs thickened, spreading enough that his joggers crept up his legs. His balls swelled beneath the fabric, stretching out into cantaloupe-sized bulges that shifted every time he moved. His abdomen slowly inflated from its former flatness, quickly resembling a small beach ball. His face had grown slightly scruffier, and a soft fuzz now dusted his belly and chest, pushing out gently under his snug shirt. And still, the transformations continued on all the bros.

Others had gone deeper. The three-can guys were waddling now—literally. Their bellies were a lot bigger. Their butts resembled beach balls, jiggling and bouncing with each step as their shorts or joggers slowly shrank, revealing more skin and accentuating their new curves. The front of all their pants expanded, giving their expanding balls enough space to grow and their cocks enough room to sneak down their legs. All the changes were evident, but the bros were too drunk to mind. Deep down, they knew what was happening. The drinks were turning them into daddies, heavily pregnant daddies with each other’s children growing in their wombs.

Zander’s transformation was impossible to ignore. His outfit now looked like a joke. His pecs had exploded into broad, milk-laden mounds, jiggling with every breath. You could see the veins beneath his chest as it ballooned outward, straining the seams. And his belly protruded round and heavy, wobbling forward as he walked. He waddled to the snack table, making his massive ass jostle behind him. Each cheek was rounded, thick, and firm, looking deliciously inviting.

Tyson was nearby, slouched on the floor and cradling his fourth beer, with his hoodie bunched up over his gut. His belly had pushed out suddenly, tight and high, like a yoga ball under his ribs. His hips had widened as his thighs spread to support the weight. And the sweatpants he wore had ridden low on his hips, clinging now to his inflated backside like spandex. His balls swung low between his legs, oversized and clearly visible under the tight cloth.

“Bro,” Tyson said, blinking as he stared down at his swollen stomach. “I feel... juicy.” He laughed loudly, eagerly reaching for a fifth can.

Jamal had become a spectacle. His chest was massive, like two sloshing tanks strapped to his torso. His tank top had morphed into a deep-cut crop, clinging so tightly to his new frame that his nipples were fully exposed, dark and swollen, and leaking faintly. His belly pushed far out in front of him like a wrecking ball, taut and smooth, with veins starting to show. He grabbed two cans, popped them at once, and double-chugged them with a roar.

“Dude! I’m gonna be the beefiest damn daddy in this house!” He shouted playfully, unaware of the actual implications of his words.

Noel had settled on a beanbag, but he barely looked like the soft-spoken young man anymore. His arms had thickened with dense muscle and plushness, his neck looked broader, and his gut rested heavily between his thick thighs. His pecs were massive now, draping just over the top of his belly, and his hands kept rubbing the round mound like he couldn’t quite believe it was real. He had to spread his legs wide to accommodate his beach ball-sized testicles that were almost resting on the ground in this position.

Across the room, the beer pyramid had started collapsing—but the center of attention was Brady. Brady was no longer just a jock; he was a mountain of beef, fat, and pregnancy. The guy had already emptied a full six-pack and was now halfway through his seventh can. His transformation pushed far beyond anything the others had seen. His body was a hulking mass of massive dad-bulk and pregnancy-swollen weight.

His gym shorts had long since transformed into hyper-stretched, glistening athletic briefs, and the fabric was so tight that it looked painted on, riding deep into the crevice of his impossibly massive ass. Each cheek jiggled like twin waterbeds, wobbling with a rhythm of their own as he took a heavy step. Every movement set them bouncing hypnotically, emphasized by the juicy slap of his balls—gigantic and sagging, each one the size of a yoga ball, glossy and veined, swaying between his thunder-thickened thighs.

His belly was otherworldly. It was far bigger than his ball, dense and weighty like an overfilled tank, stuffed with seventy unborn babies, each one adding to the immense stretch of his gut. It gurgled and groaned with each breath he took, visibly pulsing as it inflated before everyone’s eyes. The skin was flushed and slick with sweat, shiny under the party lights, and a web of stretch marks trailed along the sides. Dark hair sprouted thickly from his navel and spread upward across his torso in a carpet of coarse man-fur. His whole frame radiated virile dad energy that left some guys captivated.

His pecs had become monumental—great milky domes that jutted proudly from his chest like two rising loaves of bread. They sloshed with every breath, dripping milk from his swollen nipples that poked clearly through the shredded remnants of what used to be a tank top. That shirt was now barely more than two strips of cotton clinging to his back, framing his pecs like a spotlight on stage.

His shoulders were packed with dense, hairy muscle, thick and burly, while his neck looked like it belonged to a heavyweight lifter. His arms were dense and flushed, and his face had softened. His once clean-cut and boyish face was now fuller and shadowed with stubble, and his cheekbones were lost to the swell of dad-chub. Even his voice had changed, becoming a low rumble of baritone warmth when he laughed between gulps.

He was a living embodiment of over-the-top, blissful fertility—fattened, softened, broadened, and still eagerly pounding back more.

“Drink! Drink! Drink!” the room chanted.

Brady laughed. “Y’all are just jealous,” he slurred, raising another can. “I’m gonna out-dad all of you!”

With exaggerated swagger, he tipped back can after can. Eight. Nine. Ten. Eleven. The crowd cheered louder with each one. Some of them were too pregnant and heavy to move easily, but they clapped from couches and chairs. With each gulp, Brady’s belly pushed out farther, forcing his stance wider. His thighs rubbed, his belly bounced and shifted, and his entire torso jiggled with the movement. By his twelfth can, he was nearly spherical, moving around like a balloon filled with life.

The rest of the house was in chaos. Two bros bumped bellies trying to pass through a hallway. Both let out surprised oofs and then laughed as their bloated, heavy guts jostled against each other like two overfilled balloons.

They playfully leaned into the contact, and one of them gave his belly a proud rub. “Hey, careful. I’m carrying ten babies here.”

The other one winked, patting his enormous abdomen. “Yeah? I’ve got twenty brewing in here, dude. Make way.”

Not far away, another guy leaned against the fridge with a groan of exaggerated drama, rubbing the small of his back while the other nursed another can of Dadbod. “My hips are killing me,” he said, puffing out his lower lip. “Carrying this much beef really does a number on you.” His belly sloshed visibly when he shifted, and his tiny crop top and short-shorts shrank even more, leaving his hairy abdomen and part of his ass exposed.

The house had turned into a showcase of hilariously hot dadhood. Clothes were no longer what they were. Every item had shifted and shrunk, as if deliberately chosen to tease and flaunt. Crop tops clung to heavy pecs that leaked trickles of milk. Deep-cut tanks exposed thick tufts of chest hair and bulging bellies. Shorts barely covered anything, riding so high they bunched into wedgies and showcased cheeks round enough to let grown men sit on them. At the front, the waistbands were low, pushed down by their enormous balls, revealing the base of thick cocks.

One bro lay spread-eagled on a beanbag, grinning as his hand lazily rubbed the side of his stretched-out belly. “I think I felt a kick,” he said in disbelief. “Or maybe that was just gas. Either way, I’m keeping it.”

Nobody questioned it. Not a single one of them. Not the new hair, not the bulk, not the fact that everyone had gone from bro to daddy-to-be in under an hour. They just laughed, moaned, grunted, waddled, burped, rubbed their bellies, and kept drinking.

And in the center of it all was Brady, standing with his arms outstretched. His belly was gigantic, overfilled with over a hundred babies. His balls reached almost down to the ground. His ass surpassed the size of sofas. His pecs blocked most of his view, glistening with sweat and milk. And still, his body was expanding.

“I’m gonna need a bigger house,” he chuckled, feeling his body grow in all directions as the others erupted with laughter, not realizing the house had already begun to expand around them, changing to accommodate their bodies and their large upcoming broods.
