Decided to take a crack at some story-writing. Got a LOT of size growth, hair growth, daddy-son bonding, but most of all some good ol’ fashioned male lactation. Daddy’s been saving up his milk, boy, and he’s ready to turn you into a man. Got pretty horny writing it up, so I hope it does the same for you!
Walter admired himself in the mirror. Big swollen pecs, his belly protruding into his lap, thick leaking cock and big bull balls hanging low underneath. He stroked his meaty nipples, each bigger than an average man’s dick, and took in his huge hairy form. Every inch of him was covered in hair, from his furry toes to the carpet over his gut and chest before curling over his broad steady shoulders. Only his head was the truly hairless part of him, the bare top rimmed by a crown of hair. Walter blew out his thick mustache, barely able to handle his horniness, his bushy beard buried in the cleavage between his massive pecs.
As Walter’s hairy hands worked his meaty nipples, his pecs quivered and swelled further ever so slightly. Waves of pleasure coursed through his body. Walter loved being such a big hairy man and the attention it brought him, but he knew there was one thing he’d love even more – making another big hairy man.
For the past eight years, Walter’s pecs had steadily grown, and not just from his consistent time in the gym. See, in Walter’s family, boys didn’t go through puberty the way a normal boy would. When it was time for a boy to hit puberty, his father would undergo his own changes. His pecs would start to produce a thick, creamy man milk. As the boy grew, he would feed on his daddy and become just as big and strong and hairy. He’d become the manliest boy in his class, sure to be bigger and thicker and hairier than any of his friends by the time he left for college. The thing is, the longer the father waited before first feeding his son, the beefier and manlier his son would become. Walter’s own father could barely wait two years before letting him taste his milk. At fifteen, Walter finally suckled on his dad’s meaty man tits and experienced the greatest pleasure of his life, exploding in mass and fur. He fed on his father every day until he left for college, but nothing matched that first drop of man milk hitting his stomach.
That’s why, for the past eight years, Walter resisted the urge to feed his son. Much as his man tits demanded his son’s mouth, Walter decided instead to edge his nipples every day. He’d wanted nothing more than to blow his creamy man milk every time he thought of how huge and hairy his son would be once he fed, but he held it in. Now, his son would visit home for his twentieth birthday, and receive the best gift a boy could ask for – eight years worth of potent, creamy man milk, straight from the source.
Walter pulled a wife beater over his broad form when he heard the knock at the door. The shirt didn’t do much to cover his round hairy gut, and he liked the way his shoulder hair curled over the straps. Most importantly, it did enough to hide his nipples, since he didn’t want to surprise his son with his cream just yet. His nipples weren’t erect yet, but he knew that wouldn’t last long.
Walter opened the door to his boy’s smiling face. His youthful appearance betrayed his age. Sam was twenty years old yet still looked a small fifteen-year-old. Walter knew his son was sad about his lack of development, especially considering his beast of a father, but he had done well to build himself a toned physique in the meantime. And soon enough, his son would be more a man than he had ever imagined.
“Hey, dad,” Sam said, leaning in for a hug. He was so small, his head barely cresting Walter’s hefty gut. His head came to rest on Walter’s mighty tit, tempting Walter’s nipples to swell. “Looks like you’ve been living at the gym, these pecs are massive!”
“You’ve done well yourself, boy,” Walter replied, bringing his son in closer. He reveled in how huge he seemed compared to his son, but he knew this wouldn’t last long.
“Still hairy as ever, too,” Sam chuckled, giving Walter’s back hair a tug. Walter’s cock throbbed. God, he loved being a big hairy man.
Sam and Walter spent the afternoon catching up before settling down for dinner. They bought a few pies from Sam’s favourite hometown pizzeria. Sam had just a few slices, but Walter polished off three whole pizzas on his own. He belched and sat back, giving his gut a good slap. It felt damn good to stuff this tank.
“I wish I could eat as much as you, dad,” Sam said, “but I just can’t seem to gain weight.”
“Is that something you’d want, boy? To grow… bigger?” Walter’s cock throbbed again and started to harden. His nipples were following suit.
“Who wouldn’t? I mean, I don’t mind being small, but sometimes I wonder what it would be like to be big and strong… you know, like you.”
Walter’s nipples were achingly huge now, begging to be sucked. Huge, like me. My son wants to be a big, hairy man like me.
“You want a gut like this?” Walter said with a laugh, giving his belly a meaty slap. “Not many guys do.”
Sam blushed. That wasn’t something a boy would admit to his dad.
“Why don’t you take your shirt off, son? Let me see how big you’ve gotten on your own.”
Sam peeled off his shirt. He was comfortable in his skin, and Walter could admire his slim physique, but damn if all he could think of was his son exploding with size and fur.
Walter broke out of his reverie.
“It’s your turn. To t—take your shirt off.”
Walter’s nipples and cock throbbed. He saw his son cover up his own package.
“Besides,” Sam continued, “it looks like you’ve stained your shirt anyway.”
Walter looked down at his chest and saw that his wife beater was wet just around his nipple, meaty and poking through the material. He was leaking, his son’s mere presence nearly enough to put his man tits over the edge.
“Well, alright,” Walter grumbled. He stood up and peeled off his own shirt, baring his chest in front of his boy. He scratched at his hairy gut and the cleavage between his pecs.
“Gosh, you’re so massive, dad,” Sam said, stepping forward. Walter’s cock was at full mast now, the tent in his pants clear as day. “Even… even your nipples. Have your nipples always been this big, dad?”
Sam licked his lips ever so slightly. Walter wasn’t even sure his son was aware that he did it.
“Ha, they might’ve gotten bigger over the years.” He gave one a playful flick, nearly doubling over from the pleasure. Sam’s eyes were transfixed. “Why don’t you come join me on the couch?”
The two made their way over to the couches, and Walter was pleased that Sam sidled right up against his father’s side. His eyes were still fixed on his dad’s meaty nipples. Walter decided to risk it and started stroking his nipples, stimulating their growth into the throbbing nipcocks they were. He took a moment to revel in the pleasure, hyperaware of the milk sloshing around in his man tits. Sam wasn’t turned off by the view, instead staring intently at his dad’s wide hairy chest.
“You know, boy, it’s every man’s dream for his son to grow bigger and hairier than he ever was.”
That got Sam’s attention. His eyes were still fixed on Walter’s chest, but he looked… ashamed.
“Well, sorry to disappoint you there, dad.”
“Oh no, boy, you haven’t disappointed me! You just haven’t had the chance to grow yet!”
“Haven’t had the chance? Dad, I’m twenty years old, I think I’ve missed the chance.”
“Son, your chance is right here.”
Sam cocked his head. He waited for his dad to continue.
“It’ll be easier to show you.” Walter’s nipples were nice and swollen now. He put his hand behind is son’s head and guided him closer to his chest. “You want to get bigger, eh, boy? Just give your daddy a nice suckle, you’ll see.”
Ever so slowly, Sam’s mouth approached his dad’s fat, juicy nipple. He placed on hand on his dad’s hairy gut to stabilize himself.
Oh fuck, Walter thought. Oh fuck, it’s finally happening… my son’s about to feed…
Sam was hesitant. Walter knew there was a part of him trying to resist – it had happened to him too. But the other part of him would win, his instinct to grow.
“Just… suckle on my daddy…”
Sam stuck out his tongue and licked Walter’s fat nip. Waves of pleasure immediately coursed through his chest, through his whole body. His cock wanted to blow it’s load just from that small lick.
“Come on, boy, fucking suck it!”
Walter rammed his son’s head into his chest. Sam lost all inhibition and suckled. He sucked at his bull dad’s chest, gnawing on that fat juicy nipple. He crawled over his dad’s lap, his arms wrapped around Walter’s giant gut, his hand’s grasping at Walter’s fur. Walter wrapped one thick hairy arm around his son while Sam sucked and sucked and sucked. The pressure was building in his man tit just behind his nipple, the milk threating to burst forth.
“Fuck, boy, that’s it,” Walter said. His boy was latched onto one tit while Walter worked the other with his hairy mitt. Pleasure coursed through his body in waves. “I can feel it coming, boy… my milk is— is fucking – ugh—”
As if a dam had broken, Walter’s fat juicy nipple came straight into his son’s hungry mouth. Sam jerked in surprise, but without hesitation he drank down his dad’s warm cream. Walter’s chest kept cumming and Sam kept sucking. With every suck, Sam pulled more of his dad’s nipcum out of that swollen man tit, each suck more pleasurable than the last. Sam tightened his grip on his father’s fur and started humping the gut, lost in his own ecstasy.
Walter reached down to free his cock from his pants. He was rock hard and leaking pre, more than enough to jerk his thick cock. From his nipples to his dick, Walter’s body was wracked with orgasmic bliss.
“Keep fuckin suckling, boy,” Walter growled. He flexed his hairy pec, forcing more milk down into his son’s stomach. The release of this pent-up milk felt better than he had ever imagined. “Yeah, feed on your big hairy bull dad.”
After one more long, desperate suck, Sam leaned back, supported by his father’s meaty arm. He was panting, milk leaking out of the corners of his mouth. Walter collected it with his thumb and let his son lick it up.
“Holy shit, dad,” Sam sad. He patted his small, bloated belly. “What the fuck was that? Did you just fucking breastfeed me? And why did I… why…”
Sam looked over and saw his dad jerking his cock, and that’s when the realization of what just happened truly dawned on him.
“Are you… jerking off?” He looked down at his package. “Am I hard?”
“What the fuck is happening? Dad!”
Walter, one hand jerking his cock and the other his nipple, made no reply. His son would soon see.
Sam stumbled over to the door.
He rested one hand on the doorframe. Put his head down. It was starting.
“What – what’s this – ugh – feeling?” Sam squirmed, rolling his shoulders back. “Why do I feel so – ugh – good?”
Walter watched his son hump the empty air and saw it. It always started with the muscles.
Sam’s shoulders broadened, ever so slightly. His muscles grew in a course down his body, his back widening and his ass plumping up, his legs gaining size and definition.
“Dad?” Sam turned, his hands on his thickening chest. “Dad, I’m growing, and I feel so… good. So… horny. I’m getting so buff.” He moaned in pleasure as another wave of growth washed over him.
Walter watched Sam explore his body, his arms thicker, his abs defined.
Sam looked to his dad, a question on his face, but the fat started to pile on as if on cue. Everywhere he had just gained muscle definition, he gained a new covering of fat. It made him broader, thickened his arms and shoulders and chest, gave him a bit of a starter belly and a fatter ass. Sam closed his eyes, lost in the pleasure of growing bigger. His hands soon found light dustings of fur growing around his nipples and up to his navel.
“Dad, what’s happening? I’m finally growing and I… I love it… but why?”
Walter cupped his man tits and gave them a light squeeze.
“Eight years’ worth of the most potent man milk is stored in these swollen tits. You wanna become a real big man? Then come feed on daddy bull.”
In an instant, Sam was back on his father’s gut, his mouth latched onto Walter’s man milker. He was gonna suck his dad dry.
The two sat there, each lost in their own pleasure. Walter was finally being milked after eight long years, his man tits finally releasing their thick cream. His nipples pulsed with each suck, the thick milk forcing its way out and into Sam’s hungry mouth. Sam was finally experiencing the growth he had always craved. With each mouthful of man milk, he felt himself expand, his muscles hardening only to be covered by a juicy layer of chub. Soon he felt the fur of his own small belly rubbing up against that of his dad’s. He buried his face in farther, his dad’s chest hair caressing his face as he suckled harder.
Walter loved watching his son grow. He had waited so long for this moment, and it was worth it. With the milk now in his system, the changes were piling on rapidly. Sam was getting heavy on Walter’s lap, his chest growing into his own smaller pair of man tits, his gut ballooning outward. He soon looked like a veritable beefy ex-jock. His muscles would be impressively defined if it weren’t for the chub rounding him out.
With a loud rip, Walter heard Sam’s shorts finally give way. Sam groaned, reveling in the experience of bursting out of his clothes. Walter reached around and tore apart his son’s shorts and underwear. He cupped his sons plump, now-hairy ass. Sam started to grind his freed cock against his dad’s hairy gut as Walter snuck some hairy fingers into his son’s hairy crack.
Sam released his dad’s tit and leaned back. Walter nearly blew his load at the sight. His boy was a fucking man. A broad-chested, fat-gutted man. Fur covered his chest and gut in a carpet most men could only dream of. His face was shadowed by a new growth of stubble. His cock was leaking pre onto Walter’s own hairy belly.
“I want you to fuck me, dad,” Sam said. “Fuck me and make me grow. Give me more muscle, more fat, more fucking hair.”
Walter’s cock quivered. The pre was spurting out of his cockhead now. He did need to fuck.
Walter lowered his son onto the floor, positioned himself by his son’s hungry ass. Looking down, his view was dominated by his own pecs and fat gut, but his son was catching up to him. Lost in his body, rubbing his hands through his fur, squeezing his belly and pecs.
“Bigger, daddy, bigger…” he mumbled.
Walter couldn’t take it anymore. With his natural lube, he forced his dick up his son’s ass. Sam’s hole was tight, but it was hungry.
“Yes, daddy, yes! Give me your thick bull cock!”
Walter started thrusting. He fell forward onto all fours, his fat gut and tits hanging low over his son. Sam reached up and around his dad’s belly, wrapped his legs around his dad. He pulled Walter down and latched onto a thick nipple.
“Fuuuuuck, boy!” Walter exclaimed. He never knows he could experience so much pleasure. “Fucking suckle on me while a fuck you! That’s it, swallow my thick cream!”
Sam grew while his father fucked him. He had swallowed so much of his dad’s man milk, the growth was piling on. His gut grew and grew, ballooning out to rival his dad’s. Walter watched the fur spread from Sam’s chest over his shoulders and down his arms. Sam grasped at his dad’s tits, watched as the fur crept over his hands and knuckles. Walter felt a new, scratching sensation on his nipples, and realized his son’s beard must have grown out, too.
Walter fucked and Sam sucked, the pleasure in their bodies growing to massive proportions. Sam exploded in size, his fat and muscle piling on. He had grown so large, too big to reach his dad’s nipple in missionary anymore. Walter raised himself, used his son’s hairy outstretched legs to keep thrusting, his fat gut still rubbing up against his son’s own, and he nearly came when he looked down at his boy.
Sam’s belly and own set of man tits bounced as Walter fucked him, but it was his face that nearly pushed Walter over the edge. A thick beard, reaching high on his cheeks and down into the cleavage of his pecs, was soaked in Walter’s thick milk. It had grown so fast, and as Walter watched, it kept growing, getting bushier with each passing second. Sam’s mustache all but covered his mouth. But even higher on his head, Sam was balding. His hairline was receding in realtime.
I’m turning my boy into a real man… Walter thought. Fuck, this is so hot. He’s growing fat and hairy and fucking bald, just like a real big man.
But it wasn’t enough for Sam.
“More, daddy, give me more. More milk, more fucking,” Sam said, twisting his own nipples. He was as large as Walter now, maybe bigger. Walter knew what he had to do, but he hated leaving his son, even for just a moment.
“Daddy bull knows just what we need,” Walter said, standing up. “I’ll be right back.”
Sam was moaning and groaning when Walter left the room, and he could hear his son loving the changes even as he went upstairs to his room. He rummaged through his closet and found what he was looking for. Two suckers, one for each nipple, each with a long tube that connected the two together. He slipped each nipple into a sucker. They’d gotten bigger with Sam’s ravenous suckling and he had to force them into the suckers, but now he’d be able to fuck his son and keep him feeding.
When Walter got back to the living room, he nearly blew his load once more.
That’s… my son? He though to himself.
Sam stood a full head taller than his dad, and at least a foot wider. His shoulders, his arms, his pecs… they were massive, each bigger than Walter’s head – bigger than Sam’s own head, his beautiful, bearded, bald head. But the main attraction was Sam’s gut, huge, round, and heavy. He had to lean backwards in order to support its massive weight. Sam rubbed it with his hairy paws. His cock curved up underneath that hairy monstrosity, his swollen bull balls hanging low. With each slap to his gut, his cock squirted just a bit.
“My… boy…” Walter said, stepping forward.
Sam looked over to his dad.
“Dad,” he said, “look what you’ve done to me. You’ve grown me so big, so hairy.” Sam’s body quivered and Walter’s nipples throbbed. “You made me into such a man, dad, and I fucking love it. But I want more, I need more.”
Walter was speechless. He patted his son’s huge hairy tank, rubbed it. The fur was matted from all his son’s sweat.
“Make me bigger, dad,” Sam begged. “Please.”
“Boy,” Walter started, “There’s nothing I’d like to do more. But there’s no way I can fuck you on your back with these huge nuts in the way. Down on all fours, boy.”
Sam fell to his knees, then down onto his arms. His gut, so large, grazed against the floor, and his tits hung down in two big meaty mounds. Walter reveled at the sight of his son’s huge hairy ass, the fur traveling down two thighs, each thicker than the average man’s whole body. The fur stretched up Sam’s back, too, dense and sweaty. It coursed over he lats, his shoulders, and up his thick bull neck before stopping to make way for Sam’s bald head.
“My boy… my big hairy boy…” Walter said, looping the suckling tubes over his son’s hairy shoulders. Sam put the tube in his mouth and immediately started sucking. Walter’s nipples were ready to comply, the milk pouring out into the tubing straight to Sam’s hungry mouth.
Through the pleasure of his cumming pecs, it was Sam’s hungry ass that Walter was focused on. Walter didn’t even need to get down on his knees to fuck his son. Sam had grown so tall that his ass was nearly at just the right height to breed.
Walter rammed his cock into his son’s hairy hole. He thrust hard, his big daddy gut resting atop Sam’s hairy back. Walter leaned forward and grabbed fistfuls of his son’s fur, used it as leverage to fuck harder, faster.
My son’s a fucking man, he thought. A huge hairy man. And I did that to him. I grew him so big, so fat, so hairy. My fucking milk did this.
And it still was. Sam drank it down desperately, sucking and sucking, desperate for more mass, more hair.
Before his eyes, Walter saw his son expand to massive proportions. His ass two big hairy globes, his back wider than Walter three times over. His shoulders were gigantic, two huge boulders leading to arms thicker than a man. And the hair, oh god the hair. Sam was covered in fur, matted and sweaty, skin barely visible through the dense forest.
“Bigger, daddy!” Sam said through mouthfuls of his father’s milk. “Fucking bigger! Make me huge! Make me a giant hairy fucking bull man!”
Walter thrust and thrust. His son grew, expanded. Sam’s legs lengthened, his ass getting too high to fuck, but Walter wouldn’t give up.
I must keep fucking my son!
Walter climb onto his son’s calves, tightened his grip on his son’s fur, and he kept fucking.
“Bigger! Bigger! I wanna be huge, daddy! I – oh – oh—I’m cumming, dad! My nipples, my fat nipples are cumming!”
That was enough to put Walter over the edge. With one last thrust, he groaned and came hard into his son’s hairy ass. Load after load shot deep into Sam’s ass, into his gut, emptying Walter’s daddy bull balls. He squeezed his pecs one last time, getting those last drops of growth into his son. Sam drank them down, and he came. His nipples came, shooting his own bull milk out of his man tits, and his cock came again and again, his huge nuts happy to supply his bull seed.
“FuuUUUuuuUUUuuuckk,” Sam moaned out. He was shaking, his body wracked with an orgasmic pleasure that seemed to last an eternity. He felt it in all his muscle, in his gut and his tits and his ass. And with his father’s milk and cum, he grew, exploding in size and mass and fur. Bigger, hairier, manlier. He was huge, a massive fucking bull man. He came and came and came, his nipples and cock shooting load after load.
Sam was finally able to catch his breath, his nipples and cock still leaking their manly juices. He turned over to look at his father, his huge pecs and gut in the way. He had to prop himself up on his elbows.
“Dad… you… you’re so small…”
Walter looked up at his son’s huge form. His son’s gut alone dwarfed him, Sam’s navel big enough for Walter’s whole head.
“My boy, my big hairy boy…” Walter said.
He stepped forward and grasped Sam’s cock, thicker than Walter’s own leg. He brought it to his lips and buried his face into the slit, lapping up his son’s warm load. He looked up at his son, the cum clinging to his beard.
