You Better Fix This!

“You better fix this!”

You Better Fix This!

Seeing this picture, I can imagine Stiles playing around with some magical spells, and poor Derek getting affected by them. Therefore, in the following photoshops that I’ve attempted to make, in each in every one of them, I can imagine Derek being shocked by his transformation, telling Stiles that he better fix him...

You Better Fix This!

Derek unable to stop giggling and laughing in a goofy manner. “You, *giggle, better fix this!” he’d chuckle.

You Better Fix This!

Derek would be too embarrassed over his squeaky voice, which is a side effect of his tiny head. Instead, he’d glare at Stiles, telepathically telling him to fix this.

-- -- --

You Better Fix This!

“You, *snort, better fix this!” Derek would oink.

-- -- --

You Better Fix This!

“You better fix this!” Derek would grunt in his deeper voice, blushing at how nice it felt to press the smaller human against his bulky muscles.

“Mmmph!” Stiles would struggle to reply with his face buried in Derek’s muscletits.

Officer Counihan Ticketed A Strange Guy For Speeding, And The Next Morning When He Woke Up, His Head

Officer Counihan ticketed a strange guy for speeding, and the next morning when he woke up, his head was hilariously tiny. His squeaky voice and awkward proportions made him humiliated at first. However, the hot cop eventually came to enjoy the way his tiny head made his muscles look all the more bigger by comparison.

"You Ever Seen Biceps This Big, Little Guy?" Matt Teased, Flexing His Bowling Ball Sized Bicep And Shoving

"You ever seen biceps this big, Little Guy?" Matt teased, flexing his bowling ball sized bicep and shoving it into the smaller bodybuilder's face. He couldn't fight the large smirk on his cocky face, knowing deep down that his win was practically guaranteed since he easily outweighed every other competitor.

"...yeah," the smaller bodybuilder muttered, his eyes honing in on the small bulge in front of Matt.

The skintight pink posers easily showcased just how little the superheavyweight bodybuilder's manliest muscle was. Thanks to his massive amounts of fans and online followers, everyone knew of the imposing muscle man with the tiny cock. The other men in the gym where he worked out would sometimes gain a sneak peek of Matt's small dick, shocked speechless at the two inch nub and marble-sized balls that the stud possessed, looking all the more hilarious attached to such a hulk of a man.

At first, Matt was beyond humiliated at the thought of people seeing his microdick, but in the end, that only pushed him to grow his muscles all the more bigger.

The large Matt saw his competitor's line of sight and snorted. "May be small," he countered, "but I'm bigger where it matters." He leaned forward and performed an impressive most muscular pose, loving the look of dread on the other man's face; and not at all bothered by how tiny his bulge looked as it was thrusted forward by his wide thighs.

Tyler Hoechlin Frowned As He Looked In The Mirror, Noting That There Was A Gray Hair In His Beard. The

Tyler Hoechlin frowned as he looked in the mirror, noting that there was a gray hair in his beard. The actor sighed, frowning to himself as he studied his reflection. He took some solace in the fact that he still possessed a chiseled form with washboard abs and perfectly sculpted pecs. He’d even stepped on the scale to make sure he was staying at his peak 175 pounds. The actor was a hunk, plain and simple. That being said, he was peeved at the gray hair that was on his chin.

With some tweezers, Tyler plucked the gray, grimacing when it was off his face. “Dammit,” he huffed to himself. Although the actor was only thirty-three years old, he frowned at the thought of growing older and potentially losing roles due to him being too old, which was just how it worked in Hollywood.

He’d brought it up to one of his screen partners earlier that day, and he’d responded with: “Well, believe it or not, there’s a high demand for daddies.”

Tyler had nearly lashed out at the younger actor, pissed that he’d been technically referred to as a “Daddy”. He wasn’t old— he just had one, singular gray hair. And he didn’t even have that anymore now that he’d plucked it. All he had to do was keep up his workout regimen to maintain his chiseled muscles and maybe look into dying his hair every now and then.

Yawning, Tyler walked to his bedroom and stripped down to his boxers. He got underneath the covers, grumbling to himself as he drifted off to sleep, still irritated at his screen partner.

“I’m not some daddy,” he muttered to no one before he fell asleep, a tingling sensation settling over his body as he slept.

— — —

The alarm went off, waking up the sleeping actor and letting him know it was time for him to get up and head to the set. With a deep grunt, he rolled over, ignoring the loud creaking of the bed frame and the heavy thuds of his footsteps. He nearly stumbled when he felt that his weight was off, but he ignored it and waddled to the bathroom to shower.

Tyler paused when he looked in the mirror, studying his reflection. He felt like something was off, but there was a thick fog settling in his head, muddling his thoughts like he was on sleep medication. He moved closer to the mirror, running a beefy hand through his salt-and-pepper hair before glancing at his gray beard. He tried to think about why he was odded out by his hair, but he’d had grays before and had eventually decided to embrace them, right? He shook his head and scratched at his hairy gut that was firm and jutted out in front of him, his thick, meaty pecs resting on it. Again, he had a flicker in his brain that told him that this was wrong, but he laughed it away. Tyler knew that he gave up on having abs as he grew older, deciding to fully take on the muscle daddy look, complete with large pillowy pecs and a huge roidgut.

As per his morning routine, Tyler hopped onto the scale, having to bend more to peek over his gut at what it read: 302 lbs. H-had he put on weight… like a pound or two? The actor took off his boxers (which were ripped for some reason) and got in the shower. Tyler felt like he was going crazy as his broad shoulders kept banging against the shower tiles and door constantly. He felt awkward as he washed his large, beefy body, feeling as if his gut was hindering his movement a little. 

Weirder was that his bulk was so sensitive.

Just running his hands over his musclegut or over his nubby nipples on his massive muscletits made his ten inch cock go rock hard. And soaping up his large, hairy asscheeks made him bellow out a deep moan and shoot perhaps the largest load of his life all over the shower tiles, leaving the actor panting and spent.

His heart raced in his beefy chest for some reason, but the daddy shook it away and got out of the shower. He waddled back to his room, his large thighs rolling over one another while his enormous cock dangled wildly in front of him. He could even feel the shifting of his massive bubblebutt behind him, further confusing the actor.

“What is going on with me today?” he asked himself as he pulled on his jockstrap, his large cock filling the pouch and the back straps lifting his ass cheeks. His jeans were even plastered against his thighs, looking like they were painted on. He had difficulty buttoning them since he couldn’t see over his large pecs and gut, which was normal though… wasn’t it? He shrugged it off as he tugged on his black tank top, which was so tight that it barely fit over his massive pecs and gut. The bottom of the shirt kept riding up when he walked… well, waddled. And his large, nubby nipples poked against the fabric making themselves known to all who would pass by.

The beefy man took one last look in the mirror before he left, wondering why his brain was screaming that something was wrong. Everything was fine, he thought, right?

Tyler snorted and squared his broad shoulders, puffing out his musclegut with pride as he strutted out to his sports car. After having to adjust the seat (quite a lot), the muscle daddy sped off to the movie set. For the millionth time, Tyler felt an odd anxiety creeping up on him over the sensation of his gut brushing against the steering wheel and his pecs constantly colliding with his huge biceps.

“I need some coffee,” the daddy grunted to himself as he parked and waddled onto the set.

Everyone nodded at him like usual, some even greeting him with a hearty “Good morning!” It made Tyler feel more at ease, convincing himself that everything was alright and he was just having an off day for some reason.

He entered his dressing room and saw the younger actor from yesterday.

“Hey there, Tyler!” the young man waved at him, his eyes mischievously running up and down his beefy form.

“Good morning!” Tyler bellowed in his deep voice, immediately peeling out of his tank top and jeans. He began to shuffle around the dressing room to get his stuff ready, barely registering that he was strutting around in nothing but a skimpy jockstrap with his beefy ass hanging out for the other man to see.

The young man walked up to him, a smirk on his face as he ran a slender finger up the curvature of Tyler’s large gut, pausing to flick a large nipple.

Tyler’s head rolled back and he let out a low moan, his bulk shivering as the slight touch sent ripples of electricity throughout his beefy body straight to his massive cock, which sprang up into the air proudly. Tyler began to run his hands all over this own body, focusing more on his gut and pecs than his cock for some reason. Sure it felt nice to play with his own cock, but Tyler could get off a lot easier by rubbing his musclegut or by tugging on his nubby nipples… wait, no. That’s wasn’t right.

“I have to admit that I love the new look, Daddy,” the young man teased, his mouth latching onto a larger than normal nipple.

“Wh-what?” Tyler gasped, his face paling as he looked in the mirror at his inflated, older form. He must’ve put on over one-hundred pounds of a mixture of muscle and fat, most of it centered on his chest which suddenly felt so heavy and cumbersome. He ran his shaky hands through his graying hair and finally noticed the crow’s feet near his eyes. The entire time his larger cock oozed precum as the younger man tongued his inflated nipples.

The young man looked up and smiled at him, briefly pulling away for a second. “You look like the hottest muscle daddy ever,” he grinned, running his hands all over the older man’s protruding and uber sensitive gut.

Tyler felt himself tense up and blow his load, his gut and pecs bouncing as he came. “Ooohhh!” he cried as his cum splattered all over the younger man. As he came the old Tyler screamed as he sank deeper and deeper into the recesses of the new Tyler’s mind, being locked away in a box where he could observe and feel everything that his new body experienced, but not able to have any control over it.

“You doing okay?” the young man asked.

A large smile formed on Tyler Hoechlin’s face, and there was a fluttering in his beefy chest at the sight of the small guy. He couldn’t help but flex both of his massive arms in what was a double biceps pose, pushing out his gut with pride. 

“Hell yeah, Boy,” Tyler grunted, “Daddy’s doin’ just great. Now c’mere and suck on these muscletits some more.”
