I Tried To Inflate This Stud's Pecs, But It Looked Odd. So Then I Tried To Shrink His Head A Bit To Make

I tried to inflate this stud's pecs, but it looked odd. So then I tried to shrink his head a bit to make his muscles look bigger, and now he looks like this! Haha, still kinda nice I think.

31 Days of Derek Hale

Day 01: Headshrink

Info │ 01

Alpha werewolf Derek Hale stalked into the decrepit room where Stiles was hiding. He eyed the human curiously, wondering why Stiles was staring intently at some old looking book, only to wave his hands sporadically at an empty Coke can.

Stiles sharply exhaled through his nose and then shot one hand forward, gritting his teeth with the movement.

Nothing happened.

“Damn it,” the human cursed to himself.

“What are you doing?” Derek asked, trying to hold back his smirk. He kept his usual scowl plastered onto his face to hide his deep admiration for the hyperactive human.

Stiles jerked back and then blushed when he saw the werewolf eyeing him. “Um,” he muttered quietly, rubbing the back of his neck nervously, “Deaton said that he saw a ‘spark’ in me, so I’ve been trying to test it.”

Derek let his tough guy façade crack for a moment, his bushy eyebrows rising in surprise. “Really?” he pressed, taking a step forward, leaning in so close to Stiles that he could smell his cologne. “I used to have a pack member who had a spark. Maybe I can help you?”

Stiles’s face broke out into a large smile, making Derek’s heart flutter. “That’d be great!” Stiles practically cheered. He leaned in closer to the werewolf, showing off the spell book that he’d been studying. “I’m trying to use this shrinking spell to make the can smaller.”

Derek tensed up at the closeness, unconsciously leaning in even closer to the human, nearly engulfing him in his bulk. Although he denied it outwardly to anyone who asked, Derek had a serious thing for Stiles, and after years of repressing it, their physical closeness was too tempting to ignore. Hence, Derek leaned as close to Stiles as he could, glancing over his shoulder at the book.

“Just focus your mind on what you want to shrink,” Derek breathed, so close to Stiles’s ear that his breath wafted over the human’s face. He smirked when he saw Stiles’s skin break out in goosebumps.

Stiles gulped. “O-okay,” he stammered.

Derek couldn’t help but preen at the effect he was having on Stiles, so he decided to up the ante. He leaned in even closer, his stubble brushing up against his face. “Focus on the image in your mind,” he whispered, his lips so close to Stiles’s cheek that he could just give one little—

POOF!

Derek felt like the room was spinning, as if it were on some sort of hydraulic system. He stumbled back, his vision full of stars. Once it cleared, he stared up at Stiles who only gazed back with wide, stunned eyes.

“What happened?” Derek asked, flinching when he heard his voice. It had shot up several octaves, sounding like he was some cartoon chipmunk. Derek made a move to clutch at his throat in surprise, but froze when he looked at his hands, which now seemed to be the size of dinner plates. His hands were massive; and when he frantically looked around at the rest of his body, the rest of him was just as large. His pecs appeared to jut off unbelievably far in front of him and his shoulders were crazily broad.

Stiles paled, but then quickly grew red. “Um, well I guess I can shrink stuff after all?” he cheekily muttered.

“Shrink?” Derek demanded in his squeaky voice. “I’m huge! What are you talking about?”

Stiles bit down on his lip and held out his phone for a second, taking a quick photo before turning it around for the werewolf to see.

Derek’s stomach fell when saw that his body hadn’t grown, his head had shrunk. Instead of its normal size, his head was now about the size of a baseball, looking comically tiny atop his muscular frame. “You were supposed to shrink the can!” Derek growled, his squeaky voice completely eliminating any threatening tone to his words. “Not my head!”

Stiles held his hands up in front of himself in surrender. “You told me to focus on an image in my head, and then you kissed me!” he blurted. “So… unfortunately, I thought of you.”

Derek just smoldered, irritated that the very second he made his move, his head shrank. “Just turn me back then!” Derek huffed.

“Y-yeah! Totally!” Stiles said as he frantically flipped through the magic book. “Just gimme a sec, and then we’ll have you back to normal. I mean, hey, if you want, I can also make something else bigger on you too?” He eyed the werewolf knowingly, offering a playful smirk.

Despite Derek’s irritation, he couldn’t help but feel his shoulders relax the smallest bit. “After you fix my head,” he agreed. “And only if I get to try its new size out on you.”

Stiles flipped through the book at a much faster pace.

Day 07: Dad Bod

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07

After moving into a new neighborhood to raise his young son, Eli, Derek made the conscious decision to attempt to be friendly… at least for his son’s sake. No matter how much the werewolf hated people, he didn’t want his son to grow up friendless due to his father’s cold attitude.

Hence, Derek started to go to PTA meetings and even Parents’ Night at Eli’s school, forcing a smile onto his face whenever he had to socialize with other parents. It worked, and Derek became a hit.

Unfortunately, it worked a little too well.

A large group of moms were quickly enamored with the hunky single father. Derek was in his late twenties and he had nicely shaped muscles. Plus, thanks to his werewolf metabolism, he had impressive abs that always popped against his t-shirts.

The lustful stares from the moms only led to Derek also receiving envious glares from the dads, a majority of them having big dad bods that were complete with jiggly bellies. Derek wasn’t oblivious to the jealous looks he’d gotten from the dads, which was why he was confused when they’d invited him to a barbecue.

Again, wanting to be neighborly and hopefully quell any hard feelings, Derek accepted.

When he arrived to one of the dad’s house, he tried his best to be as friendly as possible. The host, a beefy man named Jim, warmly welcomed Derek and led him to the backyard where a bunch of the other dads were.

At first, Derek felt a little awkward at the barbecue, trying to engage some of the other dads in conversation. It always seemed to go the same way though:

“Hey, how’s it going?” Derek would ask one of them.

It seemed to always be met with an envious, silent glare from whichever dad Derek had tried to talk to. The dad would only shift his eyes from his gut towards Derek’s rigid abs, a frown set deep on his face.

Derek was about to leave when Jim walked up and clapped a large hand onto Derek’s shoulder. “Here, Man,” he cheerfully said as he handed Derek a beer, “this will help ya loosen up a bit.”

“Um, thanks?” Derek muttered as he took the offered drink, noting that the silver can lacked a distinguishable brand. Still, not wanting to be rude and alienate all the dads at Eli’s school, Derek brought the can up to his lips and took a hesitant sip.

The werewolf caught the almost victorious grins from the other dads as he drank the beer. None of them were being stealth, causing the hairs on the back of his neck to stand up.

“Wha— UURRPP!” Derek’s words were cut off when he belched loudly. He covered his mouth and blushed.

Jim only snickered and clapped Derek on the back. “Y’know Derek?” he asked, a playful quality to his deep voice. “You’re a nice guy and all, but a couple of us dads are growin’ a little irritated with the way you just stroll into town and show off your chiseled abs for our wives to gawk at.”

Derek cocked his eyebrow at the other guy. “What, UUURRPP, do you mean?” he asked, bristling at his seemingly uncontrollable burping.

Jim snorted and grabbed at his rotund belly with both hands, giving it a shake and causing the fat to jiggle. “My wife actually said, ‘Why can’t you work out and get a bod like Mr. Hale?’” he mocked, his voice going higher when he imitated his wife. “Yeah, fuck that. I hate cardio, so we all figured that it’d be easier if we made you look like one of us.”

“UUURRPP!” Derek burped, wincing when he felt a tightness growing in his stomach. The werewolf looked down and his eyes nearly bulged out of his skull at what he saw.

Derek witnessed his impressive abs pushing outwards against his tight t-shirt. Given his tight clothing, he could easily see every crevice of his hard-earned abdominals. Therefore, it was all the more jarring for him to watch as his six pack steadily went to a four pack, then two, and then flat. However that flatness didn’t last before his belly lurched forward, straining against his constricting shirt.

“What, UURRPP, are you doing to me?” Derek panicked as his frantic hands tried to press against his growing stomach, as if he could actually prevent it from getting bigger. Unfortunately, his gut only continued to pack on more fat as was evident by the way it began to jiggle as Derek readjusted his stance to account for his new weight. He could even feel his pants start to tighten as love handles sprouted and started to sag over his jeans. Toned pecs even puffed up, sagging slightly yet still showing off the impressive muscle beneath the layers of fat. His nipples stretched out to the size of sand dollars and perked up, becoming large and nubby at they strained against his shirt.

RIIIPPPP!

Derek’s straining t-shirt finally lost its battle against his growing bulk, and as he grew, Derek couldn’t stop the loud burping that echoed from his agape mouth. 

Finally, Derek felt the tightness in his stomach disappear and he breathed a sigh of relief as he stopped growing. That relief, however, was short lived when he looked in the sliding glass door and saw his opaque reflection. Derek’s previously toned musculature was completely gone, replaced with a total dad bod that was complete with a huge, hairy belly. Instead of looking like he’d visited the gym religiously, Derek gave off the appearance of a couch potato who drank lots of beer and gorged on tons of junk food. Derek looked downward and frowned when his newly inflated gut blocked the view of his lower half. He pressed both of his hands against his massive gut and gave it a tentative shake, paling when it jiggled almost as much as Jim’s huge gut.

“Here ya go, Bud,” one of the other dads said as he tossed a shirt at Derek.

Silent in shock, Derek caught the offered shirt, noting that it was a size XXL. His arms seemingly moved on their accord, and Derek tugged the white t-shirt on. Due to his increased size, his pecs strained the shirt to bursting, and his nubby nipples pressed against the tight fabric noticeably. Worse for the werewolf was that his new gut was so large that the bottom of the shirt kept riding up it and exposing his fuzzy bellybutton, making it look like Derek was wearing a crop top.

Derek’s face was beet red when he took a hesitant step forward and felt his unwanted bulk shake with every step he took, his gut protruding far out in front of him and jiggling constantly. He looked around the group of dads and realized that he was nearly on par with all of them, his new massive belly matching every other dads’ in the group.

Jim offered Derek another beer, this one with a recognizable brand which indicated that it was a normal one. “Hey Derek,” he said, giving Derek a playful slap on his new belly, sending ripples through the werewolf’s new gut, “a couple of us dads are in a bowling league and we’re lookin’ for a new player. You in?”

Derek’s words dried up in his mouth, and despite his anger, he found himself nodding, some unknown force making him calm down the slightest bit, especially as he took a sip of the offered beer.

“Great!” Jim happily said. “I don’t know if we have a uniform shirt big enough for that massive dad bod ya got there, but you don’t mind, right?”

Derek felt the corners of his mouth pull up and he ran his free hand over his exposed, hairy belly. “I’m used to it,” he heard himself say. “It’s hard to find a shirt that fits over this big belly— UURRRPP!”

Day 06: FaceApp

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06

Stiles giggled to himself as he messed around with FaceApp on his phone, playing with a picture of his boyfriend, Derek. He’d decided to occupy his time while waiting on the bed as Derek finished getting ready for their date night by playing around with random apps.

Stiles had taken a photo featuring Derek’s trademark scowl, and was having a great time playing with the lighting and some of the features. When he saw an ad for the premium edition, offering “Magical Changes”, Stiles shrugged and paid the $2.99.

A plethora of extra photo manipulation options popped up on screen, including a makeup section.

“‘Magical Changes’?” Stiles snickered as he clicked the makeup option…

Derek spritzed some of his cologne on as he got ready for his and Stiles’s date night. The werewolf pulled on a white button down shirt, leaving the top few buttons undone to let the cleft of his manly pecs be showcased. He looked like a total man’s man, and as he finished getting ready, Derek gave himself one last look in the mirror.

“Huh?” he wondered aloud as it looked like he was puckering his lips.

Then his eyes widened as his lips gradually inflated, becoming plump and more full as if he’d had some filler. His lips went from thin to a nice set of DSLs before a shimmering substance coated itself over them. The stunned Derek was helpless to do anything except watch as his lips turned pink and glossy, makeup somehow appearing all over his masculine face. His eyelashes lengthened as mascara was applied, and slight eyeshadow formed on his orbitals.

Derek went from looking tough and manly, to pretty and made up.

“What the fuck?” Derek panicked as he stared at his made up face in the mirror. He turned on the hot water at the sink and scrubbed at his face with soap, but no matter how hard he rubbed, the makeup remained. “I can’t go out looking like this!”

The alpha was humiliated at the thought of going around Beacon Hills wearing lipstick and eye shadow, complete with plump lips. His heart raced in his chest as he wondered what was going on…

“Hmm,” Stiles hummed as he continued to play around with his phone. Despite thinking that Derek did look pretty with the makeup filter, it didn’t really suit him too well. He cleared the filters and decided to start anew when a magnifying glass icon caught his eye…

“What the fuck was that?!” Derek huffed as his face changed back to normal in the blink of an eye. The makeup had completely disappeared and his lips were back to their normal size.

The werewolf rubbed at his eyes as if they were just playing tricks on him, which they must’ve, since when Derek examined his reflection, his face looked normal. That was until he felt his ears tingled slightly.

Derek gasped loudly as both of his ears seemingly pulled away from his head, steadily growing larger. They flapped a little outward so that they were forward-facing, giving the shocked Derek a full view of his massive ears that made him look like Dumbo. They were hilariously big, jutting out from his head at a severe angle.

Next, the werewolf nearly went cross-eyed as he watched his nose pack on more size. It wasn’t like a Pinocchio-growth, instead the whole nose packed on size to become larger, taking up more of his face as it jutted further out.

Before long, Derek had a large set of ears and a massive nose that made him feel like he was staring into a funhouse mirror instead of his bathroom mirror.

“What’s happening to me?!” Derek cried out as he grasped at his huge ears in a panic, wondering why his face kept changing…

Stiles could barely contain his hysterics at the silly picture of his boyfriend on his phone. He was about to call it quits when he saw another set of filters: Impressions.

Altering clearing the current filters, Stiles selected the folder and scrolled through the numerous options before finding an interesting one simply labeled “Giga-Chad”…

Again, Derek’s altered face snapped back to normal— his ears and nose deflating to their normal size, giving the werewolf a temporary sense of relief. He kept a cautious eye on the mirror lest his face start to change some more, but as more time passed, Derek breathed out a sigh of relief.

“Maybe I’m just losing my mind…” he trailed off, his eyes widening at the deep baritone to his voice. His voice sounded like it was several octaves deeper, sounding much more masculine than intended.

It was then that Derek watched his lower jaw shift and start to pull outwards. As it grew longer, it also widened significantly, giving the werewolf’s face a squared appearance. A deep cleft formed in his jaw as well, giving it a noticeable dimple. Cheekbones became more pronounced and Derek’s stubble gradually darkened.

“I… uh, I g-guess this look’s not too bad,” Derek muttered in his deeper voice as he ran a shaky hand over his widened jaw…

Stiles nodded with satisfaction over his handy work and pressed “Save” on the app, figuring that he’d show Derek later for a good laugh. He pocketed his phone and sighed as he waited for Derek to finish getting ready, starting to get impatient.

“Der?” Stiles called out. “Are you ready yet?”

“Um, coming!” Derek called out, yet his voice sounded much deeper than usual.

“Are you getting sick?” Stiles asked, concerned at the sound of Derek’s voice. He got off the bed and walked over to the bathroom, pausing at the sight of his altered boyfriend.

Derek was dressed up in his white button down shirt that showcased his muscles perfectly, and his slacks did little to conceal his massive bulge. Yet, most of the focus was his manly square jaw and high cheekbones. The dimpled chin was covered in manly stubble, oozing masculinity.

“How do I look?” Derek asked cheekily in his deep voice, gesturing at his face. “Wait— what are you doing?”

Stiles was already unbuttoning his pants, getting ready to ride the new Giga-Chad all night long.

Day 04: Hypnotized

Info │ 01 │ 02 │ 03 │ 04

At Peter’s behest, Derek had begrudgingly agreed to start seeing a therapist to help him deal with some of his anger issues. At first, the werewolf was dead set against talking to some random stranger about his life, yet once he’d actually met Dr. Callahan, the therapist had somehow managed to get Derek to lower his walls. Dr. Callahan got Derek to feel extremely relaxed in his office and open up, leading to the stud to being all ears whenever the older man spoke. The therapist clearly knew his stuff, because almost overnight, Derek could feel his mood lifting and his thoughts refusing to drift towards anything that would piss him off. He would instead spend his days in an almost giddy haze, smiling happily as he went about his work and hobbies, completely unbothered. 

Derek felt like his life had changed for the better, all thanks to Dr. Callahan.

Still, every now and then, Derek would feel a little confused whenever he’d be going about his day, and tons of guys would keep staring at him. It wasn’t the fact that they were staring that was so weird, it was the fact that Derek loved them staring.

When all eyes were on him, the werewolf couldn’t help but bask in the warmth that the mens’ gazes brought him, leading to him either flexing his massive arms or unbuttoning his shirt for them.

Speaking of shirts, Derek would usually have to force himself to wear one… or really anything at all. The thought of wearing clothes was so constricting to the young man, and he loathed the idea of covering his large muscles with any sort of fabric. There were numerous times when he’d be out in public, and it would take him a good deal of time to realize that he’d been wandering around town without a shirt on, letting his plump chest muscles be on full display. After a bit of shopping, Derek had eventually changed his wardrobe so that it consisted of nothing but skintight, synthetic material that hugged his massive muscles tantalizingly. His shorts never went past mid-thigh, and he refused to wear underwear, allowing his perpetually hard cock to press against the front nonstop. And all of his shirts (a total of three since he hated to wear them) were so small that they were more like crop tops, never passing his belly button and always having the collar so low that his pecs frequently spilled out of them. Whenever he went out, Derek was sure to attract loads of lustful stares from men.

And Derek took full advantage of the lustful staring, bedding man after man.

Not a night went by when Derek wasn’t bouncing on some guy’s dick or sucking a guy off— sometimes at the same time. The werewolf was nearly insatiable now, constantly thinking about dick or drooling over a guy who would wander into his line of sight. It wouldn’t be long before Derek would approach him, flex a bit and playfully flirt, before the two would go find a private location. Or sometimes it didn’t even have to be private. There were a few times at the local gay bar where Derek would get loudly fucked on the dancefloor by a line of guys, feeling incredibly turned on by the fact that many other men were watching.

All in all, Derek’s life had done a complete one-eighty for the best, and Derek had Dr. Callahan to thank for that. Every night when he’d go to bed and place his headphones on over his ears to listen to the tapes his therapist had made just for him, he’d dreamily smile and be extremely thankful that he’d listened to Peter and had attended Dr. Callahan’s hypno therapy sessions.

“You’re a dumb muscleslut,” Dr. Callahan’s quiet voice murmured underneath the soothing wave sounds of the relaxation session Derek listened to. “All you’re made for is showing off your muscles and fucking. You’re just a dumb muscleslut…"

@musclejedi7

Request: Love this one! I’d love to be turned into a huge guy like that. 😍😍😍🍆🍆 [Link]

-- -- --

Your life magically changed one day at the gym. You were working out after a particularly hectic day at the office, blowing off some steam at the weight pile and enjoying the sights of the muscled up studs as they waddled around.

Your attention quickly snapped away from your workout when you instantly went hard, your five inch cock rocketing to life. At first, you blushed at how tented out your shorts were, but then your eyes widened when you witnessed your cock throb and lengthen.

Every time your member throbbed, it pulled further away and thickened until your normal five incher had morphed into a nine inch beast that was nearly as thick as your wrist.

Before you could react, your entire body seemingly exploded with size. Your shoulders broadened as your back muscles thickened to larger proportions. Your arms followed suit, beefing up with serious size, turning your biceps from little mounds to the size of bowling balls that clashed with your inflated lats. Your pecs puffed up and protruded off your chest at a crazy degree, stretching your tank top to the limit. You were forced to readjust your stance as your thighs steadily grew rounder and larger, forcing you to stand almost bowlegged. The sheer size of your thighs forced your lengthened cock and orange-sized balls out in front as they pressed noticeably against your shorts. The thin material of your shorts seemingly vacuumed around your package of your ass ballooned to the size of basketballs.

As a final touch, you felt your skin start to prickle as manly hair sprouted out, covering your inflated muscles, especially your massive chest.

"Holy shit," you mumbled to yourself, bristling at your deeper voice. You examined your hulking form in the mirror, figuring that you must've packed on at least one-hundred pounds of beefy muscle.

Without a second thought, you flexed a massive bicep, marveling at its size. The action left your hairy pit exposed and the stench of manly musk permeated the air, causing your throbbing cock to twitch with want.

"Damn, wait 'til the guys at the office see..." you trailed off and your eyes widened as a fog settled inside your head. A brief flicker of panic rippled through your new bodybuilder form as you struggled to remember your office job... or really much of anything. You even looked towards one of the placards on the gym wall and scrunched up your brow in confusion as you tried hard to read what it said. Your slow brain struggled to focus on anything besides muscles and cock.

The panic quickly left when one of the other guys at the gym walked up and clapped a hand onto your broadened shoulder. "Lookin' big, Dude," he gushed.

Without a moment's hesitation, you threw both of your massive arms above your head and performed a double biceps pose. "Wanna feel, Little Man?" you asked the much smaller guy, leaning in closer.

The other guy hungrily ran his hands over your bulging muscles in awe.

The whole time, your cock throbbed as he worshipped you, and you gradually fell into your new life as a dumb, perpetually horny musclestud.
