Shady Unit

ϟ gay to straight tf, muscle growth, cop tf, forced tf, changed by surroundings, mental tf, reality tf, breeder/conservative tf

Peyton accepted his friends' dare against his better judgment; the gaggle of gays had been walking home from their early morning brunch, mimosas fizzling inside their dizzy heads, when they noticed the parked cop car with a wide open door. No pigs in sight, only an abandoned police unit just begging them to come over and snoop around. "Ohhh my god, you have got to let us take a picture with you sitting in the driver's seat, Peyton! That would be so funny!" This made the boy in question frown, blonde curls hanging in his face and obscuring his narrowed, baby blue eyes. Looking at the group, the least straight OR cop passing of the whole bunch would be Peyton, the twink runt, so that just made his friends laugh louder at the thought and push him closer to the unguarded vehicle. "Come on, Peyton, do it! You've got this!"

Making sure once more that the coast was clear, he decided that there was no harm in it. All he had to do was run over, strike a cute pose, and then get the fuck out and go home! He marched his way over, struggling a bit as he pulled the heavy, solid door a little further away so that he could squeeze inside, and then he turned to smile at his friends with flushed cheeks, hands lifted up in a double thumbs up pose. It was just a shame that the car door slammed shut before his buddies could snap their pictures, a faint murmur of gasps and sounds of confusion behind the thick shell of steel as Peyton found himself trapped and silenced within the car, panic rising in his system as he tried and failed to get the door to budge as he pressed and yanked trying to open it. All to no avail.

That was when he heard the rustling on the dashboard, the bulky pair of black sunglasses rattling in place, as if charged with energy and about to combust. He was staring at them in shock and fear when they suddenly leaped forward, opening their hinges and sliding right onto his frightened face, covering his shocked vision in a shield of dim, repressed light. Honestly, the jumping object would have been the most frightening part, if not for the pain that suddenly flared in the space between his temples. He gasped out in pain, muscles tensing, spine locking in place as shocks began to pulse through his body.

Little thoughts began to dance with his begs for mercy, his brain was a battlefield of trying to rationalize what was happening to him, and trying to ignore the presence that was steadily making itself known inside of himself. Another man's casual thoughts were overlapping his own, overpowering them. "Fuck, I can't wait for this shift to be over so I get home to my girl." Peyton grimaced, another shock rolling through him, his jaw stinging as it cracked outward into a chiseled, strong, pitch black stubbled line. The twink was confused and alarmed to hear this gruff voice speaking, especially one that gave a shit about getting home to a girl.

He reached up to pull the glasses off, trying to exert control over his spasming limbs, but then he could feel the muscles in his arms tearing apart and stitching themselves back together in an instant, his spindly arms vibrating in the air as suddenly they ballooned out into firm, solid, vascular biceps that were swollen with raw strength. Except now they were forced into a double bicep pose and no longer reaching for the glasses still trapped on his head.

"Fuccck, I just want to get home and flood her cunt. The good book says to be fruitful and multiply, my only purpose in life is to be a traditional man, to fulfill my duty as a male," the low, bovine voice kept talking despite Peyton's inner protests, his newly large and calloused hand reaching down to cup his bulge, lithe fingers fattening into sausages. His rough fingertips could feel a different and more durable fabric where his mesh shorts had once been. But that all paled in comparison to the heat radiating from his crotch, the trembling of his little nub cock as it began to engorge, fattening into a thick, girthy, vein covered shaft.

His cock head flared out into a large purple mushroom that was already leaking pre into his tight and sweaty boxers, a sun kissed hue washing across his pasty skin with every twitch of his bulking up body. He was the definition of tall, dark, and handsome. His firm jaw itched as black, wiry beard hairs burst through the coarse skin, making look him manly and intimidating. His blonde curls retracted into a dark black, traditional cut.

With what little control he could muster, he reached up to the driver's side mirror, pulling down the flap and gasping in absolute shock. Or at least he meant to, but now his permanently fixed cocky smirk could only speak with the same voice that was inside his head. "Fuck, I look clean as shit! My bitch is gonna be dripping all over my cock all night long." He watched clear as day as his now douchey, older, masculine face moved on its own accord, speaking without his say in the same dumb, harsh, jock voice he had heard earlier. Now looking at himself in the reflection, unable to control the posing body of the conceited bodybuilder cop he was trapped within, he could see what had become of his clothes. His little rainbow buttons and badges were now deadly gear strapped to his vest and belt, and his cute outfit was now a traditional and crisp police uniform.

Nothing that made up Peyton was left once that door slammed shut, leaving behind a smug and newly minted Officer Dickson sitting inside his very own unit. Flipping on the siren lights, he popped open the car door with a casual lean of his bulky body, Peyton wailing inside his mental prison at the sight of his former friends. This was their idea, and they needed to help him! He just wanted to be set free, safe to go home and far away from this awful, backwards minded brain his essence had now been shoved into.

But the massive man only sneered and glared at the group of fairies behind his dark black, emotionless lenses. "Clear the fuck out, or I'll take you all in for processing." He was okay watching them sprint to run away, vowing to deal with their presence another day. As much as he loved bringing alpha men into this world by changing gay men to serve the police unit, repurposed to better suit traditional society, he would always have a fondness of doing it the old fashioned way. And his wife was certainly gonna end up inflated with a few alpha sons in her belly once he was finished with her tonight. Peyton would just have to get used to the countless flashes of bouncing tits and squirting pussies inside his new cage. Officer Dickson wasn't going to change his mindset for anyone, let alone the skinny little queer he didn't even remember being.

Do you have what it takes?

"Young man, do you think you what have what it takes?" one of the cops said to Jack as he walked by their booth.

"Uhm, I-" he muttered. He was nervous being near them and was trying to hurry past.

"Are you sure you don't want a career in law enforcement?" asked another cop. "You look like the kind of guy who could really benefit from our services."

Jack stopped and looked at the cops, then back down at his clothes. He was wearing a loose t-shirt, jeans, and sneakers. It felt weird that they were encouraging him to be like them, but he didn't think he had the body for it. "I don't know... I'm not sure I could do that kind of work."

The cops looked at each other, then back at Jack. The one who first mentioned his outfit stepped forward and said, "You can't be serious! Look at you!" He reached out and grabbed Jack's shirt, pulling it up to expose his stomach.

Jack was shocked, but didn't resist. "What? What are you doing?"

"See that gut?" the cop asked as he poked Jack's soft belly. "We can fix that." He turned to his partners and said, "He's got a great frame. With just a little work he could be a real man."

Jack looked down at his stomach. It wasn't fat, but it wasn't toned either. Could they really make him more muscular? "Uh... I don't know..."

The other cop patted him on the back. "Don't worry, kid. We'll take great care of you." He smiled.

Jack smiled nervously. "Thanks, but I'm not sure I want to be in law enforcement."

The university student had been failing his classes and was on the path of being forced to drop out of his bachelor. Only by mere chance had he managed to pass his first year. Now, in his second year, his lack of studying was starting to catch up rather quickly.

In anticipation of not being able to continue with university, he had decided to go to his local career fair to look for possible new jobs that would fit him.

He didn't expect however to be approached by and felt up by multiple policemen seemingly promising him muscles and masculinity.

As he was preoccupied with his internal monologue, the third cop had grabbed his arm and started feeling his bicep. Jack flexed a little bit out of reflex. "You see that? He's got some muscle already. We can make you real strong."

Jack looked at his arms. He was clearly not impressed. "I want to be stronger, but I don't know about being a cop..."

The first cop grabbed the hem of Jack's shirt and pulled it up further to expose more of his gut. "You worry too much, kid. We can make you into anything. Do you want to be strong? We can give you all the muscle you need. Do you want a bigger dick? No problem. Want to get smarter or dumber? We can do that too."

Jack looked at the other cops, then back down at his flat stomach.

"I... I guess if you think I could do it," Jack said. "It can't be that hard."

"Oh, we'll make sure you meet our standards," the first cop replied as he turned Jack around. He reached down and grabbed the skinny guy's ass through his jeans.

Jack gasped and blushed. He was straight, but it still felt good. The cop squeezed his butt so hard that the skinny young man yelped. "Ahh... stop!"

The other cops laughed as the first cop continued to playing with Jack's ass. As the cop's calloused hands explored Jack's globes, the cop could feel the surface start to expand. While he was busy, the other cops reached out and started poking at Jack's chest. The last cop had other ideas. He hands found his way down to Jack's waist, swiftly pulling down his jeans, exposing more of his pale body. Jack looked around nervously as they felt him up in public.

"I don't know about this..." he said.

"As I said before, you worry too much," the first cop reiterated, slapping his ass hard enough to make the skinny man jump. "Just relax." he said with a laugh.

The more the cops touched him, the more the strain on his clothes could be felt. As he looked down he could see two slim slabs of meat on what used to be his flat chest. He was still not at the level of the cops, but it felt like there was just a little more muscle there than before. Had they really made him more muscular already? "I don't know..."

"Relax, kid." The cop in front of him turned Jack around to face him. "We'll take good care of you." He leaned down and kissed the nervous young man on the lips.

Jack was shocked at first, but he had been getting more turned on as the cops played with his body. He opened his mouth and let the cop kiss him. The man's tongue slid into his mouth and played around with his own tongue. Jack could feel his erection growing in his pants as they kissed in front of the other cops.

"See?" the cop breaking the kiss said to the others. "I told you he has potential."

Jack blushed, but didn't say anything as the cop behind him slapped his ass again. The nervous young man felt like there was even more muscle there now.

The first cop now looked at Jack with hungry eyes. In one a single movement he grabbed the overly tightened guy's collar and split his shirt in two halves. Jack was now left wearing just his sneakers and a pair of briefs in front of the cops. "Let's see what we're working with..."

He reached down and continued like before, feeling up Jack's ass through his jeans. The other cops crowded around him, feeling up his arms, legs, back, and chest. Jack looked around nervously as they felt him up in public. He could feel their fingers sliding along his skin. It felt so good, but it was also scary being at their mercy.

"He's still a little too scrawny," one of the cops said as he squeezed Jack's bicep. "We need to bulk him up."

Jack looked down at his chest. There was still not much there, but it did look fuller than before.

The first cop had again circled around now standing behind Jack.

"Let's first see how that dick measures up" the first cop whispered in Jack's ear. He could feel the cop's bulge push up against his ass. At the same time, the other cops reached out and started feeling up his crotch through the fabric.

Jack blushed and tried to cover himself, but the cops were too strong. "Stop... please..." he said softly.

The cop in front of him reached down and pulled off the skinny guy's boxers, leaving him completely naked in front of the other cops. They laughed as they got their first look at his small cock.

"Hmm, not bad but we like to have a bit of fun at the station" one of the cops said with a laugh. "This wont do."

Jack felt like he was going to die from embarrassment, but the cop holding him laughed and said, "Don't worry, we can fix that too." He reached out and started stroking Jack's dick, making it grow harder.

The other cops crowded around him, continuing to feel up his arms, legs, back, chest, and balls. The cop still holding him said, "Let's get you a proper uniform." He reached into his bag and pulled out a pair of handcuffs.

Jack's eyes widened in shock. "W-what are those for?"

The cop smiled at him. "You're going to be our new recruit. And as a recruit, you need to follow our orders. So do what I say and put your hands behind your back."

Jack felt like he was in a dream. He did as the cop ordered and turned around, putting his hands behind his back. The cop quickly cuffed him, making it impossible for him to move his arms. Then he reached down and untied Jack's shoes. "Now, let's get started..."

The cop laughed and turned to the others. "Watch this," he said with a grin. He reached into his bag again and pulled out something that looked like a weird tube of toothpaste. "This here is called Growth Factor," he explained as he squeezed some onto his hand. "It's what we use to help new recruits get up to our standards."

Jack watched with wide eyes as the cop rubbed the gel between his fingers, then reached out and started stroking his cock again. Jack gasped at how good it felt, but also at what he saw happening to his penis. It was starting to grow! The other cops laughed and cheered as they watched him get a proper dick.

"Holy shit!" one of them exclaimed. "He's growing like a weed!"

Jack looked down at his crotch in amazement. His pecker was quickly becoming a big, thick cock! He had never felt so turned on in his life. The cop continued to stroke him as he watched his own cock grow longer and harder. It felt like someone was giving him the best handjob ever.

The other cops cheered as Jack's new cock reached full length. It was now 8 inches long and rock hard, with a huge ballsack hanging beneath it. Jack looked down at his crotch in amazement. He was now sporting a massive dick!

The cop stopped stroking him and said, "There you go. That's a proper cock if I've ever seen one." The other cops laughed as they stared at Jack's new equipment. He felt like he was the biggest stud in the world with his huge tool between his legs.

"Now," the cop continued, "let's get started on the rest of you..."

The first cop passed the gel to his colleagues who squeezed out a glob of the paste in their hands, ready to mold their new recruit.

The first cop turned Jack around so he was facing away from them again. He reached down and started feeling up the skinny guy's legs. "These need a little work," he said as he squeezed Jack's skinny thighs. "But they're a good foundation to build on."

Jack looked at his legs in amazement. As the cop's hands made their up his legs, he could see his legs start to expand with pure muscle. Jack looked down at his feet in shock. His legs had grown so much that the shoes he was wearing were now too small for him.

The other cops reached out and started feeling up Jack's arms, back, chest, and abdomen. They laughed as they felt his body growing more muscular under their fingers. "He's like Mr. Incredible," one of them joked.

Jack looked down at his stomach in amazement. He now had a clearly outlined six pack. The cops continued to feel up his body, making it grow more even muscular and attractive everywhere they touched. Jack felt like he was turning into a total hunk!

The first cop stepped back and looked at Jack's new body. "Not bad," he said with a grin. "You're almost ready for your new uniform."

Jack felt like he was going to die from embarrassment from being fully naked in public, but also from the feeling of the cops touching him all over. They were turning him into a total stud! The cop in front of him untied his shoes and reached down to pull off Jack's sneakers and socks.

The first cop continued to rub the growth factor into Jack's stomach, making it grow even more toned and muscular. His abs bulged out so much that they looked like they were about to pop out of his skin. Jack couldn't believe how good it felt to have his body changing right before their eyes. The cop finished with his stomach and said, "Watch this."

He reached down and started rubbing the growth factor directly into Jack's cock, making it grow even harder and longer. Jack gasped at how good it felt to have his dick getting even larger and more sensitive. The other cops cheered as they watched him get a proper cock!

The first cop finished with Jack's cock and said, "There you go. That's a recruit who's ready for his new uniform." He reached into his bag again and pulled out some clothes.

Jack looked down at himself in amazement. He had gone from being a scrawny, nerdy university student to looking like a total hunk! The cops were staring at him with their jaws open in shock. They couldn't believe how good he looked now that he was all muscular and toned.

The first cop handed Jack his new uniform: a pair of tight, blue slacks that showed off his huge ass; a dark blue blouse that was one size too small to show off his toned stomach even if it was closed; and a leather belt to carry around his utility needed for his duties.

Jack put on his new clothes, feeling like a total badass as he did. The other cops couldn't take their eyes off him.

The first cop unlocked the cuffs from around his wrists and said, "Alright, you're almost part of our team now."

Still enthralled by his physical changes Jack had no idea what the cops still had left in store for him.

Then he realized there was one place the men had not been to yet: his face. As if on cue, two cops held Jack by the shoulder from behind as the remaining cop procured another item from his bag.

The cop held in front of Jack a small round brown tin filled with a thick white paste.

"We need you to also look authoritative, criminals will not take you serious otherwise," he remarked.

Jack could feel the cream being spread on his eye brows and cheeks. As the paste was absorbed into the skin, he understood why the other cops had restrained him. His face became incredibly itchy and it felt like a thousand small needles were pinned onto his face.

Whilst Jack couldn't see it he could feel all the small hairs that had now formed a full beard, and busy eyebrows.

"Now you look like like a real man" the cop exclaimed.

"You don't know the first thing about being cop yet, but don't worry, we'll show you the ropes" he said with suggestive wink, motioning for Jack and his other colleague to head to the patrol car.

This is my first time trying to use AI assistance in writing stories. I was inspired by fellow users like @fafnir19 and @artificial-transmutations using it in their hot stories! I must say the freedom it offers in finding a fitting picture is really useful! For text generation it's also good but you really can't expect to write everything for you! Still a lot of intervention required. To be really honest, there are still some parts which are iffy but for an experiment I think it's fine!

I did want to include some mental changes/reprogramming but aside from Jack gaining confidence I don't think I could have included it since it would make this story extremely long.

If anyone is curious about more of the technical workings on how I managed to create the artworks or text just let me know.

Hope you enjoyed it. If anyone wants I can post a couple more images that I generated but did not make the final selection!

Cop Out

--- Originally posted on 2021-06-25 by newyoutf ---

Nick, a young, headstrong journalist, had been investigating strange goings-on at the police department for months. Odd reports of trainees at the police academy disappearing while the number of senior cops seemed to increase, and without any known source of extra funding. But his only informant, a trainee at the academy himself, soon mysteriously vanished as well. Convinced the police were covering something up, Nick felt compelled to investigate.

Before they fell off the grid, Nick's informants mentioned a company that seemed to be tied up with the disappearances - New You Industries. But despite his best efforts, the intrepid investigator couldn't find any reference to such a business ever having existed. The last he heard from his mole was that a shipment was due to arrive at the police training academy in a week.

And so, seven days later, Nick found himself staking out the storage garage of the academy in the dead of night. From a long distance in the safety of his car, he snapped pictures of a man getting out of an unmarked car and handing three small boxes to someone Nick recognized the city's police chief, Chief Barrow. But this evidence was meaningless without knowing what the shipment contained.

He waited patiently for all parties to depart and snuck up on the garage, snapping the lock with bolt cutters and using his camera's flash to illuminate the pitch-black room. Nick was dismayed to find two police badges sitting on the shelf, along with three boxes, now empty.

"Did I just stake out a shipment of police badges?" Nick muttered to himself. He jumped back in fright as the lights were suddenly switched on.

"C-Chief Barrow?" Nick stammered as he turned to see the police chief standing next to the light switch.

"You think we didn't know you'd been following us?" he growled as he stepped toward Nick.

"What happened to the students?! Did you kill them?!" Nick yelled as if to try and bolster himself against the fear he was currently experiencing.

The police chief stopped in his tracks and made a sly expression, "They're not dead. They're in the station, working."

"W-what?" Nick replied with the same look of bewilderment, "I-I was told students were vanishing from the academy?"

"They got - how should I say this - fast-tracked through the program," Barrow responded with a smirk, "You're about to find how. Catch!"

Nick flinched as the chief tossed a small metallic object at him. Reacting instinctively, Nick caught it in his hands. It was a badge, just like the two behind him. He shuddered and his hand tensed around the badge. Incredible energy surged up his arm and spread through him. He desperately wanted to let go of the enchanted badge, but he couldn't.

"Sorry, but we can't have you reporting on this," Barrow chuckled as he exited and slammed the garage closed behind him. As the door crashed down Nick's legs gave out and he fell to his knees, his fingers still firmly grasping the badge. The young journalist was terrified, but at the same time engrossed in the power bubbling through his body. Finally, his fingers unclenched and dropped the badge to the floor, but the damage had been done. Nick pushed onto all fours and let out a long moan as his body began to change.

His legs stretched out from his slacks, exposing more and more of his shins. Likewise, his arms extended from his sleeves while his entire torso was pulled longer and longer. "What's ah... happening to me?!" Nick groaned as his cock hardened to full mast.

Muscles fluttered and twitched all over his body. They grew across his arms, bulging from his biceps and triceps as his shoulders grew wider, tearing at his shirt. Pecs slowly protruded from his bony chest, growing large and dense. Abs rippled out along his stomach, leading down to a sharper, V-shaped set of cum gutters. His legs surged with strength, copious amounts of muscle growing and forming in his thighs and calves, stretching his fly apart and revealing the wet, hard, bulging underwear underneath. Behind him, his flat butt began to press outward, bigger and rounder, matching his thick, muscular thighs.

He couldn't help himself, clasping at the exposed muscle as hairs darted across the surface. Soon he found himself grabbing fabric, much to his surprise. He opened his eyes to see his tattered clothes repairing and reshaping into the uniform of the local precinct. His bulging arms still strained the new shirt. A bulky, heavy vest replete with a radio and utilities formed over the top.

"Ngh! Fuck!" he grunted, bucking his hips involuntarily as his feet stretched and pressed against his tight leather brogues just as they too morphed to accommodate his changing body. The pressure lowered as his size nine dress shoes rapidly bloated outward into heavy, size fourteen boots. Long toes shredded through his socks, clutching at the insole as they stretched along with his extending soles.

Nick clambered to his feet, clutching his head, only to feel his hair pulling inward, short and tidy. Not only that, but he could feel some hair vanishing completely from his temples, leaving him with the slightly receded hairline of a man maybe five or more years older than he was. His fingers cracked as they began to slide longer across his scalp, pushing through the neat, handsome cut of hair. He held the stretching, trembling hands in front of him, gasping as he watched them swell huge and powerful.

He slammed his massive fists into the wall with a deepening roar, feeling his head creak and reshape. His features broadened and enlarged. A strong chin and jaw pressed out of his face and light stubble sprouted from the skin. "Must be... some way to s-stop this..." Nick groaned, his eyes widening at the sound of his new and completely unfamiliar voice. Nick frantically reached for the police badge on the floor that had started all of this, hoping, praying for some way to revert his changes. His eyes scanned the metallic chest piece, but there was no sign of any method to stall or revert what was happening. Rather, he caught a glimmer of his new reflection in the shiny metal. Nick's wide, handsome jaw fell open at the sight. Not only did he look easily seven or more years older, but he looked completely different; he couldn't help but think he looked much manlier and sexier.

Meanwhile, downstairs, his hard cock ached for touch as it stretched down the leg of his pants. "Oh, god!" Nick gasped. His balls swelled larger while his python thickened and lengthened against his muscular leg. He couldn't contain himself anymore, pulling the fly on his new pants down and fishing his swelling cock out, allowing it to stretch into the open. He couldn't believe how big it had already gotten, easily inches larger than what he was used to. Reluctant but unable to resist, he gripped it in his hand and pumped, growling loudly with every stroke. Nick was too busy relishing his increased size and virility to realize his mind was filling with policing skills and years of experience. Before he knew it he had an eight-inch weapon in his hand. He couldn't take it anymore; his height, his muscles, his size. He felt so virile, so masculine, so powerful. Screaming in ecstasy, Nick blew load after load against the concrete wall.

Once the post-orgasmic fog lifted, Nick quickly tidied himself and brushed a large hand through his shorter hair, dazed and confused. His memory was intact, but they competed for attention with new skills, desires, and traits. The muscular sergeant lifted the garage door with ease, spotting Chief Barrow waiting for him in the car park just in the distance.

"Ready, Sergeant?" Barrow asked.

"I... I...", Nick stuttered as he looked down at his muscular frame, suddenly noticing how much taller he was now. His huge cock twitched in response, causing Nick to moan just a little. "Y-Yes, sir!" he parroted as he proceeded toward the car, eagerly accepting his new life as Officer Nick Collins.
