Locked Boyfriend

When Hunter agreed to be locked, he thought it was just with a chain around his neck. He felt a sense of security with it around his neck, a sense of commitment from his boyfriend. When he woke up the next morning with a cage around his cock however, he couldn't have been more shocked, his morning boner pressing against the metal while his boyfriend played with his body. 

Hunter didn't know why he felt like putty in his boyfriend's hands while the two made out. Everything felt more...

Pig Rubber

You loved the bulging look of rubber thongs. There was something about the smooth sheen of the material and the elastic tightness against the skin that drove you crazy. Not to mention how well it supported the junk it contained. You couldn't help but fantasize how it would look on you. You hoped to accentuate your own package when you bought one, wanting to look well endowed for hungry bottoms. 

You should have paid more attention to the store you had patroned. Within the week a pa...

Head Fucked

You didn't know how long you'd been there that night. You were placed in a dark space with the heavy smell of manly musk trapped in your head. You knew it was caused by the thick wet rod taking up your entire space in your mouth, its rich taste filling your mind. Not to mention the countless other loads you'd taken that night. All you felt was the urge to take the current cock deeper, force it to cut off your breath as you tried to swallow it.

You felt fur on your forehead and rough han...

Workout Headhones

The only thing Savi wasn't happy with was his size. He felt he couldn't be more lucky with his body: he had a full head of hair, smooth unblemished skin, little beard growth that was easy to manage. His only issue was that he felt small and weak. He felt no matter how much he worked out, he just couldn't put any muscle mass on his body. He wasn't trying to bulk up much, wanting to be more toned and show definition. He didn't want to end up fat like a brute.

Savi was trying to find anyth...

Relaxing Beer

One swig was all it took to get Dad hooked on the beer you picked up for him. He had always been a hardass on you, previously a professional athlete only interested in staying fit. He made sure to stick to the same diet and exercise, trying to engrain the same values in you by force. He'd treat you like trash if you did anything against his beliefs, belittling you in an attempt to control you. He was in your phone every day trying to control you. You had had enough.

Once you heard of an...

Monkey Head (POV)

Abe hadn't been taking the protein shake 'Monkey Head' long before he started noticing a major difference. He had always been big, but never had any definition until now. He couldn't get enough of seeing his body in the mirror, sharp toned curves forming under his skin from his calves up to his shoulders. His arms had changed the most, his biceps growing permanently visible above his widened forearms. He could see his veins ripple simply by flexing his fingers.

He could tell it wasn't j...

Speed Bag

Boxers can't look away. As long as their arms still work, their eyes are trapped by the speed bag, unknowingly hypnotized by its swinging movement. Their minds go numb as all their oxygen is taken up by their muscle, their eyes glazing over as their thoughts are taken up by a single purpose.

They don't know how long they've been doing it for, each visit growing longer as their arms widen thicker and thicker. The image sticks in their memories, taking up more space in their head the long...

Caged Game

Devin lost another game, his rating further falling on global. He thought playing it would distract him from his swollen cock in its cage, stimulated erect by the ring at its base. At least, as erect it could be. He felt the constant wet flow of precum escaping it into his jockstrap. His entire skin was sensitive from how limited his blood could fill his tool, it instead flowing to other locations. He couldn't escape his arousal, making it more difficult to think.

All Devin wanted to be...

Swine Tattoo

It started out as a joke, calling Carter 'swine'. He would always take everyone's leftovers if they allowed him. His friends didn't mind the frugalness, knowing the type of guy Carter was. They began even offering him their food expecting him to just eat it. It became a running joke that he couldn't say no, his friends beginning to call him a pig, a victim to his gut. Carter had been small at the time, no thought of offending his slim figure. Once he got the tattoo however, everything changed...

Bearjamas

Ben had to admit how effective the 'Bearjamas' sales tactics worked on him. He kept seeing ads for the PJs, huge men of different sizes displaying the brand on their bodies. Ben wasn't a big guy himself, but definitely had an eye for those sort of men. He loved the ones that looked like big plush pillows. He'd imagine tackling them and being embraced by their warm enveloping figures, their soft flesh like a weighted blanket on him.

The purchase was a no-brainer. He felt lucky the brand ...

Monkey Head

A new batch of protein shakes, Monkey Head, had started taking over the gym. It spread like wildfire as men witnessed the results. Their figures were growing huge, ripped with muscles, becoming giant brutes. It wasn't long before it became one of the more popular supplements, all its users overlooking the side effects.

The men who used it were able to spend more and more time in the gym, their bodies driven to be in a state of constant work. They didn't realize how their testosterone le...

Home Spouse

Cad wasn't sure he made right choice when he got married. His partner seemed to make them fall into traditional roles becoming the breadwinner, expecting Cad to handle everything else. Cad was to take up all the house chores, managing the bills, cooking, something that took his entire day to day life giving him little personal time outside from when the husband got home.

Cad did not enjoy feeling stuck, helplessly watching as his routine changed him. He'd had a fit body before, having b...

Monkey Rings

You thought the piercing's name was a joke when you got them, 'monkey rings'. You played along, thinking they were just normal nipple rings, not realizing that the shop you had gone to was in any way special. You'd been wanting them for a while as way to emphasize your nipples, get them to show under your shirts, maybe be a little bit more sensitive. As they recovered, however, you learned they served a different purpose.

You watched over the course of the month as hair spread out aroun...

Throat Dom

You couldn't breathe with his belt wrapped around your neck. His cock was settled deep in your throat, growing more snug as he pulled on the end of the leather, pleasuring himself. Your lungs were spasming, trying to bring in air, only serving to lodge his member further down your neck.

You thought this was what you wanted, having fantasized about being dominated in this way before. You wanted to be tied up, have your mind fucked into oblivion, be left in a mess with your body used to i...

Dad's Cigars

You shouldn't have gotten into your dad's cigar stash.

Your dad had always been a huge man, overweight with a huge ball gut, carrying it in front of him everywhere he went. He didn't try to hide it either, even wearing tight shirts that pronounced it, his midriff visible in all of them. A huge cigar couldn't look more at home in his mouth, surrounded by a thick beard the color of the clouds he constantly emmited. His shirts had gained permanent ash stains right under where the tip of th...

Daddy Skinhead

I walked into the bathroom to find my roommate with a generous amount of cream on his head, covering the sparse hair on his skull. He had lathered it as thick as shaving cream would be, hiding all skin underneath. If I had to guess, I would have assumed he was shaving his head, but that didn't seem like him after fighting with his thinning hair for so long.

"Dude, what are you doing?" I asked, surprised.

"Trying this new hair growth product. Just got it today, reviews say results ...

Athletic Briefs

Men think that just having athletic underwear will make them more active, be viewed as being more masculine having a sporty appearance. They ignore the boxers and supporters other athletes would tend to prefer, instead going for the briefs they're so used to. They never consider how those articles are made for a different purpose.

As men start wearing the briefs in their daily lives, they feel the changes start to happen. They feel their stances change, their muscles growing toned as th...

Secondhand Smoke (Smoke Force)

Rob didn't smoke. At least, not anymore. Having quit a while back, he couldn't understand how everyone else in his department suddenly picked it up. It had to be from the new recruit that had started bringing cigars to the office. Everyone seemed to want to be like him. It spread like wildfire, all his coworkers now with a cigar permanently stuck in their mouths. The office space was contaminated with a constant haze, forcing Rob to want to spend almost all his time outside of the building. H...

Pupsitting

You had been asked to housesit by a friend while they were away, asked to watch the place and make sure there were no issues. When you arrived however, you couldn't have been more surprised to find a pup in a jockstrap standing in the hallway. They were muscled and furry all over, body on full display, but would communicate with grunts and whines. You were taken aback, not sure what to make of the situation.

You searched the house and found a note from your friend, explaining that the p...

Team Party

Each football party ended the same way for James. He'd wake up in the morning with a pounding headache and his ass in numb pain, accompanied by the dull sense of pleasure from his bruised prostate. His underwear would be around his knees, and he'd have no clue where his pants disappeared to. The smell of sex sat heavy around him, his sweat and the fluids of his teammates soaked into the coach underneath him- not to mention the sizable deposit of cum leaking from his crack.

James was the...

Summer Bros

You used to make fun of the typical "bro" guys all the time, with their snapback hats, beards, and lack of care for anything other than their ripped bodies. You and your friend would laugh at their excessive tattoos and the fact that they didn't even bother wearing deodorant, embracing their body hair and letting it grow wild. You couldn't understand how anyone could live with such little concern for their appearance.

At least, until you saw your friend again during a beach vacay after ...

Ape Mind

George watched as a new supplement began taking over the gym, 'Ape Mind'. He saw it appear in online forums, his friends using it, watching their progress. It couldn't have seemed to be more effective, turning men into massive beasts, all the evidence pointing toward the substance. George had no doubt about it as he started using it every day.

The changes couldn't come faster. He felt he had laser focus in the gym for his lifts now, feeling as though he had more energy and could go for ...

Growing Role

Ethan had been thrilled when he was selected for the promotion, at least at first. He was selected to fill in as the manager of the team he had been a part of, and definitely had earned it given his hard work. He was now in charge of the progress of each team member, keeping them on track and ensuring the project was completed on time. It took a little getting used to being called "boss" by his former peers. As his time in the role went on, however, he learned just how much more was on his pl...

Leather Boy

Leather was something Ben's dad had always engrained into his son. To the father it was a symbol of power and authority, showing wealth in having the money for authentic tradework. Leather jackets were the best for keeping warm, leather belts for waists. Leather shoes for formal events or boat shoes for casual wear.

Ben didn't really understand it growing up. For him it was just another piece of clothing, something that could be replaced. It was just some engrained quirk in his dad that...

Plush Boyfriend

Danny was relaxing on the couch when he noticed his boyfriend Kurt laughing, taking pictures of Danny in his reclined state. Danny looked up amused. It couldn't have been his boxers that his boyfriend had seen so many times, so why was Kurt laughing?
"What are you doing?" Danny asked curiously.

"Just wondering when you said you were heading back to the gym." Kurt replied, a sly smile on his face.

"You know I go to the gym" Danny sighed, "I've just been on break."

"Really?...

Faun Glide

"The instructions should have been more clear" Julian thought, thinking about the bottle of lube he had picked up. It seemed to have been a rebrand of an existing one for Halloween, the name now "Faun Glide". "For sex-crazed bottoms with fur" The package said. The image of a hairy man with goat legs accompanied the text, displaying a cartoonishly sized tool hanging from their groin and a puddle of precum forming at their feet. Looking down at himself now, Julian realized he must about look th...

Pig Bath

Nolan loved taking baths now. It started when he came across some soap brand, 'Pig Bath', on clearance. It was supposedly all-natural, using real fats and oils produced on a farm. It must not have been doing too well, especially since Nolan had never heard of them. The prices were dirt cheap however, a whole line-up of products all meant for ambiance - candles, salt, soap, scents. He'd been needing a reason to take time and relax in his bathtub, hoping to enjoy it, and felt this couldn't be a...

Bear Park

You were walking along in the park when you passed a shirtless older gentleman in glasses going the other way. You couldn't help but be disgusted by the view of their body. Underneath their beard, hair spread across their entire surface, so thick in some places that you couldn't see the skin underneath. Even though their figure was built, all you saw them as was an ape. You couldn't comprehend who in their right mind would allow their body to become so brutishly unattractive, much less expose...

Gym Perks

Vance was upset he had to move for work, forced to leave behind his old gym and the routine he had built in the city. He was frustrated needing to find a new power lifting gym that would suit his needs, particularly one that opened early enough for his schedule. After some searching, he finally found one, heading in early one morning to get his exercise in.

He was pleasantly surprised to receive a free pair of headphones as a perk to signing up. He expected them to be rather cheap, but ...
