ONLY MENS HERE NOT GIRL / WOMAN

My dad bet his brother 20$ that he couldn’t drink all 4 quarts of beer in one sitting. Little did my dad know that uncle eats this much on a weekly basis. As usual, my uncle won the 20$ and stumbled away with a huge hard gut and a tighter pair of pants. Dad tried to hide it, but I knew he got aroused by his brother’s gluttony.

After dad went to sleep, I checked in on his brother. He was laying naked in bed, moaning softly with how big he felt. I stayed there all night rubbing his gut and congratulating him for his arousing show. Good night uncle…

Jason looks down,staring at his new form. He can’t believe he went from being  scrawny to being this. Jason begins to touch and feel his newly obtained muscles, a part of him thinking he should be concerned with the sudden growth, but another part of him dismisses that concern as he begins to smile dumbly and begins to flex. ‘Fucking hot’ he grunts, looking at himself in a mirror at the gym. Jason mind begins to dim the more he flexes forgetting his old life as well as his IQ dropping drastically till all he can think about now is working on maintain his physique, getting bigger, and sex.

[stupidhimbo]

He's a shy guy, always has been, getting fully red at the slightest shit, even after growing into this massive himbo. That only makes his dick even more hard when you tell him to show off and take his clothes off slowly just for you.

“I had to leave the meeting early as I could feel my belly starting to strain the buttons on my shirt. As soon as I got outside all the buttons burst off immediately allowing my squirming belly to balloon out in front of me! What’s happening to me?!”

[megamusclefan]

After the painstakingly slow process of lowering yourself on his absolute beast of a cock, your asscheeks finally reach his balls and you are stretched well beyond your limit!

It was such a tight fit, not sure how much longer you can take it, you ask him if he's already close.

The movement from nodding was enough to send him over the edge, me pulls your face into his solid pecs, threatening to crush your face, whilst a what feels like a gallon of cum explodes so powerfully, you feel yourbody rise slightly. Your body is filling up and excess cum pours out of your overly stretched asshole

His orgasm finally subsides and his beasty cock remains deeeeeep inside you. He continues to breathe heavily in your ear, then he whispers "now that's out of the way, we can have some REAL fun!". He stands up with you still impaled on his still rock-hard cock, holding you with his incredibly strong arms and proceeds to fuck you at an alarming pace - you're thankful the bountiful amounts of cum inside you as you need all the lube you can get if you want to survive a raging cock like this!

He uses many positions and lays you on various pieces of furniture whilst his athletic energy never ceases. Your feet don't touch the floor for nearly three hours, and in that time, he has 5 intense orgasms inside you, bloating your stomach.

[megamusclefan]

I lay on the bed, covered in sweat and panting hard - I must have passed out. My body aches and my stomach is burning, I feel like my insides have been scrambled. As I gently press my bloated and pained stomach, I feel a small squirt of warm leakage from my ass. I put my hand to it to see what it could be, but my fingers slip right in - when did I become so loose down there? Three of my fingers just slipped into my usually tight hole... Then I remember the guy from the bar!

This guy was gorgeous, tall with jet-black hair down to his shoulders, his skin was smooth, dark and every inch was packed full of muscle, he was an absolute hunk! I invited him back and we made out. I wanted to take it slow, but he continued stripping, revealing more and more of his godlike body, finally showing off his supreme endowment. But when I said he was too big, he got rough.

My bedroom door flies open, and the abusive man from last night struts across the room in only a towel, holding a cup of coffee.

I can smell my shower gell on him, from here, it's oddly comforting despite the genuine fear I have right now. Whilst I was unconscious, he must have helped himself to a shower and to things in my kitchen.

My body aches too much to move. He stares at me with his intense eyes, he downs the coffee in one go, making an exaggerated "aah" as he finishes.

"Right, " he says forcefully, smashing the mug on the floor as he talks, "time to finish you off!" my towel is torn off his waist, revealing his monstrous appendage.

[megamusclefan]

"damn, you're the first person who hasn't run away when they've seen my cock... Don't lick it too much, if it gets too hard, it'll never fit inside you.

"... That's it, lay back against my hand, I'll support you... Raise your ass and I'll ease it in. Ooooh, you feel tight, but you're stretching nicely around the thickening shaft, damn, nearly fully erect now, I'll push further in veeeery slowly. Oooh fuck, you feel so good, I can feel your organs moving out of the way.

"Look at your stomach, its bulging from how far my dick is! You can't be human, I've never made it balls deep without inflicting severe internal damage!

"That's it, I need you to be my official fucktoy... I'll pay you handsomely for it - but first, I wanna see how you balloon up when you take my load... Fuck! Here... It.... Cummssssss!!"

[megamusclefan]

Fuck I can't believe he took it all - these jock-types are usually fucking wimps when it come to taking something this big!! He's taking me like a fucking champ. All 16 fucking inches.

Ugh, and the sound of my balls slamming into his cheeks... Fuck... They're full to max right now, I've been saving this load for a whole week, they're the size of coconuts... Fuck.... They're about to burst...i should warn him befo-ugh-ARGHfuck... FUCK. take it. TAKE IT! Let me FLOOD THEM GUTS... Take it ALL

Fuck lad, that's it, CHOKE ON MY CUM! cough it up, lad, that's it, cough it up... I know it's thick, it don't come up easy, but I don't want you drowning in it. Not yet, at least, I've still got another round in me.

The Bigger Person

"What are you doing?" Terry asked as he peeked over his boyfriend's shoulder.

"Nothing, why?" Geoff responded as he quickly closed his phone.

Terry reached around and snatched the phone out of his hands. He opened the phone to find the confirmation of an Uber order.

"You're ordering out again!?" Terry scolded. "Babe, we talked about this. I thought we're gonna start eating healthier."

"Just cuz I'm delivering it doesn't mean it's unhealthy." Geoff defended.

"I can see that the order is for Crumbl cookie."

"Fine! You caught me. So what." Geoff scoffed.

"So what? Would you grow up! You've gained 40 pounds in the last year, this isn't healthy."

"That's just what happens when people hit thirty, they gain a bit of weight. What's not normal is someone spending multiple hours every day at the gym. You barely even work, you should be glad I make the money to feed us in the first place." Geoff started to shed a few tears.

"Maybe a few pounds would be normal, but you've jumped off the deep end. You sit on your ass all day and wonder why you've turned into the fat ass that you are. I'm trying to be the bigger person here and help you lose the weight." Terry continued.

"The bigger person!? All you do is judge how I look. Why don't you be the bigger person and admit that you only loved me because I was fit."

The words echoed around the room like a shockwave. Terry stopped dead in his tracks, as if the words froze him in time. Then, all of a sudden, his body started to grow. The once 5"7 Terry quickly shit past 6 feet as his body stretched and his limbs lengthened to match. His shirt looked like a crop top as he passed 6"3, and his basketball shorts didn't even cover his knees anymore.

Geoff couldn't help but watch as his boyfriend gained nearly a foot in height, he just kept tilting his head back to keep eye contact. Little did he know, that was only the beginning.

The tight abs that peeked under his tiny shirt began to soften. It was subtle at first, just a small layer of fat that softened his six pack. But then it sped up. Fat piled into his midsection as his stomach swelled into soft belly, and his tight hips widened until his love handles spilled over his waistband. His shirt rode up to his chest as his belly continued to grow until it put Geoff's beer belly to shame. It hung over his shorts, showing off his enlarged belly button.

Geoff didn't even have time to react before the rest of his body started to grow as well. His juicy pecs inflated into thick man tits that ripped right through his shirt. His shoulders broadened to match his hulking height, and the layer of fat growing over his arms made him look even stronger.

His shorts tightened around his legs as his thighs grew larger than his own head, making it hard to walk without them rubbing together. And his fattened ass cheeks won't make it any easier.

Meanwhile, Terry's hands and feet start to grow. They nearly double in size as his fingers swell and his feet widen. He drops the phone as his hands grow too large to easily handle it. At the same time, the bulge in his skin tight shorts started to grow, snaking its way down the side of his leg until his dick was nearly hanging out of his shorts.

Hell, even his face began to change. His cheeks puffed out slightly and his sharp jawline softened under a layer of fat.

As the transformation came to an end, Geoff simply stared at his massive boyfriend, unable to find words to speak.

Terry, now able to move again, simply reached down and picked up Geoff's phone off the floor. He groaned as he stood back up, seemingly not used to having to lift such a heavy body.

"God, this things really weighing me down." Terry chuckled as he patted his exposed belly. "Good thing the food just got here." He said as he looked out the front door.

"You want some of my Crumbl cookie?" Geoff asked, still bewildered.

"Do you even need to ask that?" Terry scoffed. "And once we're done, I'll make you a nice dinner and stuff you until you can barely walk. How's that sound?"

Geoff smiled, "that sounds great."

The bigger your biceps get, the smaller your mind becomes. It was a sacrifice you didn’t think twice about making back when you were a scrawny nerd who would have done anything to get bigger. So, when you were given the opportunity, you gladly agreed to give up small pieces of your intelligence in order to make your muscles grow. You had intelligence to spare, you figured. And you’d know when to stop. All you wanted was just a little bit of muscle, you had told yourself.

But having muscle, getting bigger and bigger every day… Watching the muscle grow and expand right in front of your eyes… You had no idea that it would feel so good. And the more of your intelligence that you gave up, the less you cared about studying and learning and passing your classes in school… It just seemed so much easier to let it all go and just keep getting bigger….

Now you’ve got the biggest biceps of anyone you know… Sure, you can hardly string a proper sentence together any more… But those biceps, bro… It was all worth it, wasn’t it?

[jockboyaj]

Bryce couldn’t believe that he met a hot Doctor who was running a muscle growth study. He had always wanted to put on muscle but his skinny frame seemed intent on remaining that way. When the Doctor informed him that he still had one spot open, he quickly volunteered to join the study.

Throughout the next year, Bryce would arrive to the Doctor’s lab once a weak and strip down naked so measurements could be taken. Then he would watch a few videos about a new workout technique or diet option. At first these videos were annoying to watch. Sometimes he swore he heard someone talking in the background or saw a random word quickly flash across the screen. When he told the Doctor about this, the Doctor just told him to stopping worrying about it and ignore it so that is exactly what Bryce did.

As the months went by, Bryce found himself incapable of focusing on his studies and found that he only cared about his workouts and diet. He eventually stopped going to classes. He continued to ignore all requests from his teachers and guidance counselors. He just found school so boring now that he couldn’t even give it a moment of his attention anymore. All that mattered now was giving the study his all.

He eventually received a letter that stated that he flunked out school but by the time it arrived, he found that he couldn’t read it so he took it to his next appointment with the Doctor. As the Doctor read the letter to him, he smiled at the end, put his hand on his pumped up pecs and informed him that he was now ready for Part 2 of the study. Bryce found himself cumming uncontrollably as the Doctor said that.

As part 2 of the study started, without even realizing it, he started to isolate himself. His friends and family no longer interested in. They would always act concerned about the changes he was making to his life but he knew deep down that they didn’t care. The only person who cared about him and wanted what’s best for him was the Doctor so he would do anything the Doctor says.

Eventually, Bryce was evicted from his small apartment but he didn’t worry. Today was his least appointment with the Doctor. He couldn’t wait to see if the Doctor would be proud of his growth.

He quickly rushed to the Doctor’s office, went to exam room one, removed his shirt, and waited. The moment the Doctor entered the room, Bryce’s cock started yo throb. He started yo tell the Doctor that he was evicted but the Doctor told him that he was already aware and had a solution for that problem but first, all he had to do was watch a new video.

When Bryce awoke, he has no memory of how he use to be but found that he didn’t care at all about that. He knew now who he was and now, he was the Doctor’s perfect muscle toy. All he must do now, is serve the Doctor so he was so happy when the Doctor informed him that the study was a success and that he was ready for Phase 3.

As Bryce listened to the Doctor explain Phase 3, he found his cock start to constantly leak. For phase 3, Bryce would be sold to the highest bidder at a secret auction. Once sold, Bryce would be programmed into his owner’s personal sex toy.

When the Doctor finished speaking, he found himself getting on his knees and crawling to the Doctor. He was so happy that the Doctor chose him for the study that he started to deep throat the Doctor’s cock. He just didn’t know any other way to thank the man for transforming him into the perfect muscle slave.

As the Doctor started to cum, Bryce felt at peace. Soon he would be an owned boy and sign away all his rights. He couldn’t be happier because after all, all that mattered was the Doctor’s needs and if the Doctor needed him to be a muscle slave, then that is what he would be.

Cum addicted himbo

He's addicted, he needs your cum like he needs water, it's simply intoxicating to him, he goes all day thinking to the moment when he will come back home, get on his knees and finally get your cum in his mouth, he lives for it, and you love to give him what he wants.

[qingtong]

[allalphas]

“Mmmm you suck so fucking good, baby” he moaned.

"Cup my balls and twist and squeeze them!" he ordered me.

"You like that my cock keeps hitting the back of your throat, don't you, you faggot cum slut pig?" he grinned as he asked me.

“God, damn I love that throat!” he grunted.

"Hold on, get ready, I'm gonna skull fuck you now. I'm gonna grab you head with both my hands and let loose," he said.

"I know you want this, my big asian cock as far down your throat as possible, go ahead, squeal like a pig as I push harder and deeper down you throat!" he barked as he pummeled my hungry and eager throat.

“Fuck yes, fuck yes, fuck yes,” he sighed.

“Fuck, your mouth feels insane!,” he almost howled.

"You are my slut, you are my slut! Whimper! Squeal! Moan!" he shouted.

“Fuckkkk! Fuckkkk, take it, take it, slut, fuck yes, take my cum!” he yelled as he held his cock deep down my throat and shot his load. It was heavy and thick.

He pulled out and was still cumming, so he glazed me good.

"Good boy, let me smear your face with my cum! You are my slut, my personal cum slut," he said teasingly.

whoops… is it that noticeable? 😬

Jerk Off Material

Shit huff huff I’m close. C’mon there’s gotta be a good one around here somewhere.

Nah not this, I’ve already jerked to that one last week, this too... hmm maybe tumblr has something new.

Don’t think I’ve seen this writer before, let’s see.

#muscle tf, #cock growth, #himbo tf.

Yeah... this is the one. Hmm, I'll just skip to the good parts, I'm sure it wouldn't hurt.

He glossed over the contents of the link sent to him, not paying attention as the words magnified the ongoing transformation in his brain and body, each scroll speeding up the growth and slowing down his thoughts.

Heh, there it is, this guy’s not gonna know what hit him. All these muscle-obsessed writers sure love a good dumbing down, huh? Can’t blame them though, must feel nice to be a meathead. Growing big and worshipping yourself...

Oblivious to the changes, his pecs started to swell with muscle, forming a meaty shelf that accompanied his new big dark nipples. They were toned yet squeezable, a symbol of a good himbo.

Fuck. My chest feels pumped just reading that. Though, they do look huge as hell right now, ngh, my nipples also feel extra sensitive... but I guess they've always been like that right? So soft but hard... I can- a-ah! I can definitely get off with this. 

His thick fingers fumbled with the site, getting harder and harder to scroll as his arms bulged out. All the friction caused an intense musk to waft through the air, reeking of pre-cum and testosterone.

Mmpfh- feels a little different today, these calluses rubbing up and down my cock like that. Guess the gym's paying off huhu, can't get arms as huge as these without a little wear and tear. So fucking big.

Next were his back and shoulders, which widened themselves to perfect proportions, complementing his newly carved abs and obliques that begged to show themselves off to the world.

It's getting so hot in here, shit, I'm getting sweat all over. But it smells so... so ggooood. W-Why am I so horny... I just want to... need to flex.

A loud moan erupted as his thighs pressed together, threatening to compress his balls from their sheer size. His ass followed suit, rounding into a juicy bubble butt that sent chills up his spine and into his brain, relieving it from its duties of thinking and processing for pleasure and lust.

NgHHH - god I'm throbbing like hell down there, this dude sounds like an absolute beast. Mmmnhh that ass must be so grabbable, so fuckable. Just like mine. No room left to spread, everything's so tight.

He pounded his palm like a wild animal in heat, sending drops of pre-cum that drenched everything with its scent. Every pump only made his dick grow further, adding inches upon inches, as his balls dropped with heavy cum, becoming so long and thick until he had no choice but to cum.

Huff huff I can feel it coming, I'm close, too close, I'm gonna mmfph - just take every inch of my fat fucking cockkkkk UGHhh!

So much cummmm -Ooooughhhh - again and again, spilling everywhere, more fucking MORE-

Fff-ffuckkkkkkkkkkkk that was… that was fucking amazing bro… I gotta share this one with the rest, it felt soooo... uhhh, real yeah real. Dude in the story sounds just like me, huhuhuh, sexed up and horny for more.

Mmm... fuck I still got another load left, I wonder if there's anything else around.

------ ------ ------

I'm back again! Wrote this really quick one because I NEEEEED to get back to writing. I had wayy too much stuff going on during the holiday season, but hopefully 2026 will be the year I write more!

[builtforbreeding]

Bro can’t get enough bating his cock with dudes online. He goes from video room to video room milking himself for hours. He used to feel ashamed about masturbating solo for hours but now doing it with other men on camera it feels so connected and positive to proudly pump his prick. Bringing himself to the edge over and over and over. Seems like all he does now is hit the gym and bate his cock. That’s all he needs to be a happy boy.

[parkertfs-deactivated20260118]

(via builtforbreeding)

It doesn’t take long for the side effects to set in. His cock gets bigger with each sesh, pumping blood into it day after day has a serious impact on his girth, thickening the shaft while his length barely progressed an inch from his original. His balls empty on their own now too. He just has to think a horny thought and he starts to leak, precum flowing like a tap. He can even cum just by waiting long enough. His balls get too full? They empty soon enough with no effort on his part. He can’t help it. It has ruined multiple shorts and underwear so now he just wears a jockstrap. It dries up most of the cum just fine, the rest soaks into his pubes and cooks up his new, purely masculine, cum-flavored-B.O. Add onto that the brain fog he can’t escape from due to the horny stupor and you’ve got the beginnings of a top rated pole, ready to ride.

Be the pole.
