You live to grow
Reblog if you think about your body thickening and exploding with muscle more than anything else. I want to be your friend.
Thank you! I love this so much. <3 Didn't thought I would won that, but I promise to put this new body to good use. Gonna have some fun with it too, of course. ;P
I'm so sorry, I'm not sure how I missed your instruction that guesses for your anniversary post is to be sent to your inbox. đ I kinda rebloged it, but let me do this properly.
Is one of your favorite actor Henry Cavill?
Before I start, I just want to say that I never expected that Henry Cavill would be the name arriving in my inbox more than any other. Is it because our names are so similar? Sure, Iâve used him in a fair few stories in the past, both here on tumblr like âMorfoniâs Festivalâ and over on Patreon with the likes of âDirecting Supermanâ, but to have no less than five people certain that heâd make my top ten was a surprise! Luckily for one of you, Cavill was indeed a correct guess (although he did have to duke it out with one or two other guys to solidify his place), and it just so happens that you were the first person to deliver his name to my inbox!
Now of course we need to consider how to get you into Henryâs body and Iâm trying to keep things interesting for each winner, so Iâll be taking another avenue with you. This involves plucking your consciousness out of your body - donât worry, Iâll have one of my employees slip into your body and live your life on autopilot in your absence - and then getting it settled in its brand new home for the next six months. The complete weightlessness is a little alarming at first, I know, but youâll only stay that way for a few minutes at most. Trust me, in no time at all youâll be feeling very solid again!
Ah, there he is: Henry Cavill. Take in that gorgeous sight - the tall stature, the bulging muscles, the confidence with which he holds himself. Heâs a lucky man for winning the genetic lottery in such incredible fashion but heâs also done a lot to turn himself into the A-List superstar that he is today while still maintaining his nerdier roots. Of course from now on that luck is going to be yours, because your spirit is being catapulted directly into his body at this very moment! Youâre sucked in through his open mouth and immediately begin to stretch out, filling every inch of his body with your presence. Itâs not exactly an easy takeover - it never is with these overconfident Hollywood types - but with a little help from your good friend Mr Cavanaugh, it wonât be long before youâre asserting your dominance and forcing him to stay put in the passenger seat!
Itâs a remarkable sensation, feeling yourself spread out in a body much larger than your own, but equally pleasurable. I can tell as much too, thanks to that growing tent in the front of your deliciously tight jeans! Every little movement might feel strange at first given how much heavier and bulkier you are now, but with a bit of flexing Iâm sure youâll get used to it. Go on, give those arms a try. Lift them up and watch the biceps rise into mountains as you strike a pose! How about you have a go at popping those delightful pecs for us too? Youâre putting on quite the show! I hope youâre enjoying it just as much as your audience is!
Interestingly enough, youâve entered Mr Cavillâs body at quite the unique turning point. With no more Superman projects lined up and with him having turned down future seasons of The Witcher, youâve got a relatively clean slate ahead of you! Of course, you could continue things as normal and get some exciting new acting roles lined up for the next six months, but you also might want to use this freedom to be a little more daring. I can imagine it now: Henry Cavill as the star of Magic Mike Live! With a body like that, youâd have men and women all but begging to be the one youâre grinding up on each night. You may even want to take things a step further and forge out a new career in adult films or as an OnlyFans star! So whatâs it going to be, Henry? The choice is yours!

I know everyone fluffs up their fantasies for the sake of fantasy, but I want to address some pregnancy/general reproduction misconceptions that are becoming pet peeves:
Labor does not start when the water breaks. Labor starts at the first contraction and can go on for tens of hours, even multiple days.
Water breaking usually isn't a big gush of liquid like a water fall
Water breaking is not an indicator of crowning
Water breaking happens long before the cervix is dilated enough to give birth but it is an indicator of active labor, which just means labor is getting more intense (Active Labor generally lasts 4-8+ hours)
Milk comes in after birth, usually a few days after
A belly usually won't start to be visible until around 3-4 months into a pregnancy, and barely at that
The vulva is the actual hole. The vagina is the inside of the hole. The cervix is the base of the hole. The cervix opens up into the uterus.
The clitoris is both inside and outside the body. Clitoral vs vaginal stimulation is actually stimulating the outside head that's visible vs the ends just outside the vaginal walls
Fucked Silly
You didnât think much of what heâd said at first. He was just a Grindr hookup, and tops will say literally anything. The message didnât even crack the top 5 weirdest things youâd been sent. But still:
âGonna see you fucked silly.â
It was so specific. Okay, maybe you looked like a bit of a dummy, with your sturdy muscles and habitual smile. But you were getting a doctorate! There was nothing silly about a PhD in Historiography.
âGonna see you fucked silly.â
You looked at the message one last time as you waited rang for him to unlock the door of his building. You rolled your eyes. Bullshit tops.
But as his fat cock penetrated your hole, you started to feel weird. Your thoughts started to slow down and drift away. âWhatâs⌠happening?â you groaned as he bottomed out.
âYouâre getting fucked silly, like all the other guys I top,â the top told you, and shifted inside you. You felt his cock rub up against your prostate and some of your thoughts popped like shiny, glittery soap bubbles.
âNoooo,â you moaned, shocked at how slutty your voice sounded. âI donât wanna be a silly boyyyy.â You were smart, right? You were getting a Historoâ Histrioâ Hisâ a big degree!
âYeah, you do,â said the top, starting to fuck you harder. âYou wanna be a silly bottom boi with big juicy muscles.â
âIâm moooore than a joocy muscle boiiiii,â you moaned, caught between bliss and horror as your whole body lit up from the fucking. More and more of your thoughts, memories, and knowledge slipped out of your grasp and vanished as he kept on fucking. You tried to hold onto things like your high school math class and your favourite show, but they vanished so fast you forgot youâd ever known them.
You felt your brain getting lighter and lighter as everything inside it dissolved and went away. As the topâs rhythm broke down with approaching orgasm, you moaned wantonly and fucked back into him, desperate for stimulation as the last of your smarts vanished.
The top came, and the sensation of him filling you up with his cum ripped away everything that you had left. You spurted all over the bed with an empty-headed groan. The sight of all the globs of cum on the sheets suddenly struck you as hilarious, and you started to laugh. âHuhuhuhuâŚâ
The top pulled out. âAnother happy customer,â he said, patting you on your broad back.
You twerked back at him, feeling empty. You flipped over and grinned up at him. âI wanna go dancingggg,â you whined in your new dumb, slutty voice. âLetâs go partyyyyy.â You were just a dumb, airheaded himbo with bouncy muscles and a goofy personality.

Youâd been fucked silly.

never let people forget that the main target of nazis are jews.
Lgbt people are targets, black people are targets, other poc are targets.
but their main targets are always Jews. donât forget about us. Donât forget that theyâre targeting jews.Â
because everyone seems to be doing so, and its not fair. Weâre real people, being targeted. our death, our elimination, is being Claimed as a main goal publicly on television by these neo-nazis.Â
You donât get to leave us out of your solidarity posts about the victims and targets of these white supremacists.Â
To do so is to perpetuate the very antisemitism that these people are spreading. To do so is to be complicit in these neo-nazis goals.Â
I know most people making posts in solidarity with the targets of these people mean well, but you canât leave out their main target, for any reason.Â
Please, if youâre not jewish, reblog this.Â
If it's okay for me to participate, perhaps Henry Cavill? đ
What do you think of transforming all of your followers/fans into men you find hot to celebrate 10 years of Cavanaugh? It could be very hot to meet up with a few Chris Evansâ, Alex Crockfords, Nick Bosas or others you find attractive and you of course, to celebrate together.
Now this is an idea I can absolutely get behind! How about we even make this into a little game?
I've picked ten of my absolute top crushes whose bodies will be up for grabs in this event. Whoever manages to successfully guess one of the men on the list wins his body! This will be on a first come first serve basis, so get guessing!

Froy and Zane were the picturesque It Couple. Two young gay men who were unafraid to be affectionate in public was enough to bring social media into an applause.
The cutesy couple made out in the bedroom one night, getting ready for some sexy time when Froy paused.
He pulled back for a moment in confusion, having slid his hands up his boyfriend's shirt. "Um, Babe?" he asked. "Did you grow out your chest hair?" His fingers ran through a thick pelt of fur that seemingly covered Zane's pecs.
Zane looked back in confusion as well, having been naturally smooth for years. "No...?" he trailed off, looking downward at himself. His voice disappeared in his throat the second he saw the new chest hair curling over his collar. "What the hell?"
The second he looked down, Zane's eyes nearly popped out of his skull as he watched his pecs grow. The mounds seemingly inflated and rounded, the buttons on his shirt popping off as he grew. The hairy muscletits came into view as they burst out of his shirt, being capped with large, nubby nipples.
Not to be outdone, Zane's gut followed suit. His abs disappeared before his stomach grew outwards. His gut steadily inflated until he had a complete hairy muscle gut that protruded far out in front of him.
"Wh-what happened to me?" Zane panicked as his hands ran over his rotund belly. "I'm huge!"
Before Froy could attempt to comfort his larger boyfriend, flinched when he felt his own shirt begin to constrict around him. His jaw dropped when he looked down at himself, watching as his own chest inflated and grew hairy.
The two boyfriends could only watch in shock as they grew larger and much hairier. Their arms grew in size, their biceps packing on much more meat. They had to shift their stance on the bed as their asses inflated and rounded out, their thighs getting bigger too.
As a final touch, the boyfriends felt their faces start to itch as beards sprouted out over their smooth faces. Their baby faces were completely altered as wrinkle lines formed near their eyes and their cheeks even rounded out some more, their necks widening to account for their deeper voices that uttered from their beefier bodies.
"Babe, what happened to us?" Zane cried out in his deeper, baritone-filled voice.
"We look like daddies," Froy muttered as his hands explored his larger and much hairier body. Despite how freaked out his was over his mysterious transformation, the sight of his now older boyfriend with a large set of fuzzy pecs that rested atop a large musclegut turned him on.
"What?" Zane asked when he saw his dady of a boyfriend hungrily staring at him.
"You really make a sexy daddy," Froy playfully growled, reached over and running an admiring hand through his boyfriend's thick chest hair, pausing to thumb a nubby nipple.
Zane bellowed out a low moan and allowed to himself to be felt up by his larger boyfriend, totally succumbing to his new life as a large muscle daddy.

The Things I Live For:
MUSCLE GROWTH
THE PUMP
SEEING OTHERS GET OFF ON MY BODY Reblog if you feel the same.Â

When "The Rut" hits, a bull is at the peak of his virility. His already impressive masculinity grows even more so as his body produces many times amount of testosterone. His massive muscle will look so pumped like it was just freshly worked on in the gym. His manly hair carpets even denser all over. His beefy cuntbreaker throbs with needs as his balls continuously over-produce inhuman amount of hyper potent cum, capable of knocking up his boys with even a single drop. His musk is filled with pheromone that can get even the straightest of men into Heat, horny and fertile.
Even more so, however, is the drive to breed. The bull's reproductive instinct, strong even at the calmest of time, goes into overdrive as the desire to knock up bottoms and propagate his Alpha DNA becomes unbearable. This goes on from a week up to a year in most bulls.
Image is on my other blog: https://beastcz.bdsmlr.com/post/636821813 The young jock didn't know what to expect from the new supplement his bros recommended to him. They swore it gonna blows his mind. And he could see why, his bros looked like they have been on gear for years, and with none of the usual side effects on their junk, if the giant bulges he saw was anything to go by.
He didin't think it would be near this literal, however. It's been a couple of days since he took the unassuming capsule, and he felt amazing. Too amazing. He could feel how his much his usual thoughts were slipping away, pushed deep beneath the onslaught of horniness and drive to get jacked and manly.
He's been cumming three huge load in the past couple of hours alone, and there's no sign of stopping. It's almost like his balls produced more cum than he could get rid off.
Everything felt so sensitive; The muscle filling his rapidly too small clothes, the hair sprouting all over his body, his nose picking up his increasingly intense musk and pheromone, especially his growing cock and balls.
Not that he has the mind to care anymore, what's left of his mind is devoting to experience all this pleasure and satisfying his overwhelming desire to breed.
