Metabreeders pt 1

Karim paced nervously as he waited for Arthur to meet him in the lobby of

his apartment complex. The muscle-bound gym instructor wasn't used to being

so jittery before a date, but things had been going well with Arthur and

Karim always got worried when he got close to a guy. If he wanted to keep

on seeing Arthur, he would need to come clean about something, and not all

guys took it well.

Sure, some people loved Karim's "gift". It came in handy when you worked at

a gym, for sure. But some saw it as freaky or disturbing, and others got a

little crazy about it in the opposite way. Karim didn't like being

fetishized for his gift, and he especially hated feeling used.

But Arthur was a cool guy, it seemed. He definitely had some fire in him,

and he was certainly competitive, but Karim liked these qualities in a man.

He enjoyed small games with Arthur, competing to see who could lift the

most weight or do the most crunches, though no matter who "won", Karim

ultimately won in the end. If Karim could bench more, he enjoyed fucking

the frustration out of Arthur, and if Arthur could curl more, he enjoyed

showing him who was really boss.

Hell, Karim even liked it when Arthur sucked his cock. For the most part,

Karim was not a passive person in the slightest. He got bored during sex

when he wasn't doing something to the other guy, and for that reason

usually didn't like getting blown or ridden. Even skull fucking felt boring

to him when he could instead be coring out a man's hole. But blowjobs from

Arthur were fantastic. You'd have to be a sucker to turn down that man's

mouth. He could deepthroat to the base, and his beard against Karim's

thighs sent shivers through them both.

But before they could go any further, Karim had to be upfront and honest.

No point in getting attached if Arthur was going to freak or get weird.

Arthur walked out of the elevator, a smile splitting his scruffy face as

soon as he saw the jock waiting for him in the lobby. He walked straight up

to the taller man, resting his face in the crook of his neck as they

embraced.

"Where you taking me tonight, Karim?" Arthur asked, easily reaching for

Karim's hand as they left the apartment complex. "Think you can top the

date I took you on last weekend?"

"I think I can top anything you deal me," Karim said with a smile, though

his heart wasn't quite in the quip. He tried his best to calm his nerves,

or at least provide a facade of normalcy.

"Promises, promises," Arthur teased back, squeezing Karim's hand. They

chatted about their weeks as Karim led Arthur through the balmy streets,

the summer evening's orange light painting the sidewalk a lazy amber while

wildfires burned in the windows overhead. Nobody glanced twice at the two

men holding hands, except maybe for a few jealous gay dudes checking out

the body building hunk.

When they arrived at Partito Salsiccia, a fancy Italian restaurant ran by

the esteemed Chef Hector, Karim made sure to open the door to get a glance

at Arthur's shapely ass as it walked through. It certainly wasn't the

biggest or bounciest he'd ever fucked, but Karim was always someone to

focus more on what's inside a man. In this case, a seven inch colon that

could take a non-stop pounding.

After ordering, Arthur reached across the quaintly set table to place his

hand over Karim's. "Hey, are you okay man? I hope I'm not moving to fast

for you, I'm sorry if holding your hand on the way over was too much." He

realized he was holding Karim's hand as he said this and removed it. "I

really like you, but we can take things slower."

"No, I really like you too. Really," Karim responded, reaching to keep

Arthur's hand in his. "It's just that, well, I should really come clean

about something before we go any further. It's part of the reason why I've

always used condoms with you, and I understand if it's a deal breaker, but."

"Karim, don't worry about it. I'm not one of those jerks who cares if

you're poz or not. I'm on prep, I'm cool with playing safe. I really like

you for who you are."

Karim smiled. "Thanks for that, but that's not quite the issue. I'm not

sure if you know what a metabreeder is?" Arthur shook his head blankly.

"Well, I'm one of them."

"Okay," Arthur said, his voice making it clear that he wasn't about to get

shaken by unknown terminology. "What's a meta breeder?"

"I'm not sure of the history, or how exactly it works. I don't know if it's

magic, or science, or genetics, or voodoo. But basically, my cum changes

people." Karim held his breath.

"Changes? Like how?" Arthur didn't seem freaked out, which Karim saw as a

good sign, but he didn't seem to fully understand yet. "Like, if you breed

me am I going to become a metabreeder too?"

Karim chuckled a little. That wasn't too bad of a first question. "No. I

can guarantee that. People are born metabreeders, you can't become one. My

uncle explained it to me. He was a musclebreeder like me, so he was able to

pass on his experience."

"Musclebreeders? Sounds like a porn site."

"If you saw my uncle, you'd probably think he belongs on one. That man had

boys hanging off his like flies. He'd have a new twink every month, and by

the time he was done with them they put on like thirty pounds of muscle."

"So are you saying he changed them?" Arthur asked, slightly incredulous.

"Yeah. With his cum," Karim replied. "The way he explained it was that

every time he shot in a man's ass, it'd put a pound of muscle on their

lower body. Every time he filled up a man's stomach, it'd put a pound of

muscle on their upper body. I don't think my numbers measure up quite to

that exactly, but maybe I'm just less potent than he was."

"So... is that why you're so jacked?"

"What!? Cuz I fucked my uncle?! Fuck no dude!"

"Nononono," Arthur put his hands up to defuse the situation. "Cuz you're a

musclebreeder. Does that make you super jacked too?" he asked. "Besides, I

can't see you bottoming for anyone anyway," he added as an afterthought.

"Oh, nah. Sorry. I love my uncle but I've had creepy gay guys imply that

shit about us cuz we're both gay. But nah man, I got this body cuz I worked

for it. This was from hours at the gym."

"But you're saying you can give that kinda body to anyone if they suck your

dick?"

"Yeah... pretty much. Well, maybe not this good, but close," Karim said with

a smirk.

"If you told me that on the first day we met, I'd think it was a terrible

pickup line," Arthur said. "Sounds like a bad pop-up ad. `Want to lose fat

and gain muscle quick? Just bend over for Karim!'. Not that you need any

extra advertisement."

"It'd be false advertising anyway. My cum doesn't make you lose fat, just

gain muscle," Karim said as the food arrived. "So these carbs are all on

you!"

"I'm sure we can burn them off later tonight," Arthur said with a wink

through a mouthful of ragu. Karim took the first few bites of his lasagne

before hesitantly asking:

"So, this doesn't freak you out at all?"

"Nah, dude, not really. I mean, if you're telling the truth, what's the

downside? I get more fit, right?"

"Right."

"Then I don't see the big deal. If you're making this up, you're kinda

crazy, but I think a little crazy is cute. And if you're not making this

up, then I can start posing a challenge for you in lifting contests."

"You wish," Karim snapped back, some sauce dripping from his lips. He

blushed as Arthur laughed.

"So... what else can you tell me about metabreeders? There's gotta be some

sorta downside right?"

"Well, some guys go crazy for my cum. I had one ex who would pester me to

fuck him two, three times a day so he could grow bigger. I don't think it

was my cum doing that to him though, I just think he had a growing fetish.

He was already somewhere in the range of 280." Karim shrugged. "I can see

why he wanted to grow more, I'm not kinkshaming here. But I just didn't

like feeling like I was a protein shake dispensary."

"Well, I promise not to go crazy for your cum like that. Though it is kinda

hot imagining how big you could make a guy."

Karim laughed. "Haha it definitely is. My uncle's longest relationship was

with a boy who started out at like 120 pounds, soaking wet. A year later,

he was topping out on 300, of pure muscle. On a 5'7", 20 year old

former-twink, it looked pretty intense."

"You ever thought about selling your cum in shakes?" Arthur asked.

"Nah, like I said I don't like the feeling of being used like that. Even if

I make money off it. Before I met you, I would fuck some of the guys I

trained, especially the ones who loved to skip leg day, just to give them

the extra boost up. I figure I'm just doing my job."

"That's kind of hot, dude."

"But I haven't done that for awhile. The last guy I did it to just got

invited to join the gym elite a month or so back, and I don't fuck them.

Especially now that I got a boyf- guy I'm dating."

`Real smooth, Karim,' he thought to himself. But Arthur just smiled.

"Give it another date and we can make it facebook official," he said. Karim

smiled back.

And then the topic of conversation drifted away from Karim's reproductive

peculiarity. They chatted about the newest episode of *Come West*, about

how Buck was finally opening up to Curly and about how Joe needed to have

more shirtless scenes. They talked about the strange wolf sighting near the

docks. They laughed about stories from their past, about the time Karim had

accidentally entered Volur's Sauna, the lesbian steamroom across from

Seidrman's Bathhouse, eliciting a number of sarcastic quips from the women

inside, the best of which was that no matter how much he worked his pecs,

he probably wouldn't be the topic of affection there, and about the time

Arthur had decided the lines for the bathroom at Club Lux were too long and

had gone outside to pee in the alley to find two bears getting blown by a

twink who looked like he was a little over his head but was still eagerly

enthusiastic.

"You didn't give him any help?" Karim asked as he gave his card to the

waiter. "With your blowjob skills you could've had both of them finished in

seconds."

"Honestly, I was thinking about it. Only reason I didn't was cuz I

recognized one as a guy my dad plays poker with." They both burst out

laughing. The laughter melted into the smiling lull of two slightly

intoxicated people who just shared a joke and wanted to share another. "So,

there's no downside at all to being a metabreeder? I'm asking cuz I really

want you to fuck a load into me tonight, and I just wanna be sure."

"None at all. Unless of course..."

"Unless?"

"Unless you got a pussy hidden somewhere that I don't know about.

Metabreeders can't have children. My uncle was bi and he learned the hard

way."

"Why not?"

"I don't know all the details. I just know that if a metabreeder knocks

someone up, bad things happen. I was only a kid when it happened, and I

only got a glimpse... but it was like the hulk. On steroids."

"Yeah?" Arthur asked, horrified fascination in his eyes.

"They kept it in the basement. It was only a few weeks old, but bigger than

my dad. It looked like one of those roided-out competitive bodybuilders.

The adults were all talking about what to do with it, and I wandered into

the basement. It would've killed me if my uncle hadn't intervened. It was

afraid of him for some reason. When I was older, my uncle told me that was

when he first suspected I was a musclebreeder like him. He thinks that if I

wasn't, it would've snapped my neck without hesitating."

"Whoa..." Arthur whistled, wide eyed. "That's crazy, Karim. What did they end

up doing with it?"

"I don't know. My uncle doesn't like talking about it. Sounds like a cheesy

horror story, I know, but I promise I won't jumpscare you." Arthur chuckled

nervously as the waiter returned. "But don't worry, that can't happen to

you."

"Eh, it'd be worth the risk anyway," Arthur said with a wink.

*-* * -**

When they got back to Arthur's apartment, neither man could keep his hands

off the other. Karim felt exhilarated that his secret was off his chest and

Arthur had taken it so casually. Arthur was if anything even hornier for

Karim's cock, and was curious if his cum was as magic as he claimed.

In the elevator, they made out furiously, surprising an older lady who got

on at the third floor. "Oh, don't mind me boys," she said after the shock

left her face. "I've lived in this town long enough to see more than my

fair share of young bucks like you going at it."

Despite her encouragements, the men kept their lips to themselves for the

rest of the trip up, though Karim couldn't help but grip Arthur's jean-clad

ass in his hands, pulling the shorter man into him. Arthur let out a

stifled squeal, which turned into laughter from all three people.

Arthur fumbled with the keys to his apartment as Karim continued to paw at

his ass. He had barely opened the door a crack before Karim pushed them

both inside, catching Arthur and pulling him against his body before he

knocked the other man down with his exuberance. Arthur leaned into the

strong man, whose arms wrapped around him in a sturdy embrace, kissing his

lips feverishly with his arms pinned to his side.

Karim loosened his grasp enough for Arthur to step away, reaching back to

grab Karim's hand and pull him to the bedroom. Karim resisted though, his

greater strength pulling Arthur back into his kisses, before he hoisted the

man up into the air. Instinctually, Arthur's legs wrapped around Karim's

waist. He could feel a lump in the bigger man's jeans pushing against his

ass.

Karim carried Arthur to the bathroom, where he set him on the bathroom

counter. He was pushing Arthur against the mirror, almost bending him in

two, before he let up, leaving the smaller otter breathless. "Strip," Karim

ordered, stepping back to take off his own shirt.

Arthur was stunned for a moment, as he always was, when Karim revealed his

ripped body. Each muscle was stenciled perfectly onto smooth skin. His pecs

jutted out over a sixpack, the lats giving Karim an almost upside-down

pyramid look. Karim smiled at the admiration he was receiving before

repeating, "I said strip, boy."

Arthur scooted off the counter, ripping his shirt off before his feet hit

the floor. His stepped out of his jeans, his cock springing free

immediately. "Freeballing, huh? Lucky that lady in the elevator didn't see

anything," Karim mused as he stripped off his own pants and underwear.

"Nah, she's cool. I've seen her at pride rallies stuffing ones into gogo

boy's thongs. She's a bro," Arthur said, kneeling before Karim's manhood

and opening his mouth expectantly. Karim grabbed him by the armpits,

lifting him up and almost carrying him over to the scale by the wall.

"Before we do this, I wanna see how much you weigh," Karim said.

Arthur stepped on the scale impatiently, waiting for the display to

stabilize. "One fifty two."

"Ready to hit 160?" Karim asked as he sank to his knees in front of Arthur.

He quickly devoured the hairy man's cock, taking it all the way to the

pubes in an instant. Arthur wasn't long; in fact, he was shorter than most

guys he knew, but he was also thicker than the same guys. Karim really had

his work cut out in stretching his jaw, but Karim loved nothing if not a

challenge.

Arthur admitted that he was getting pretty good at sucking him. Most guys

tended to scrape their teeth, and he didn't blame them, but Karim was

managing to keep it mostly smooth. As Karim bobbed up and down on his cock,

Arthur leaned back against the wall, panting. The numbers on the scale

fluctuated wildly as the muscular demigod sucked the cock of his hairy

partner, both of them moaning at the heat of the situation.

Before Arthur could cum, Karim had stood up again, this time looping one

arm under Arthur's and the other under his knees, lifting him up bride and

groom style. Carrying him to the bedroom, he tossed the smaller man onto

the sheets, grabbing his legs and pulling his hips to the end of the bed

before he had even finished bouncing.

Karim descended like a vulture to eat out Arthur's furry hole, the natural

musk of his crack invigorating his tongue. He started out with fast,

furious licks around, before beginning to penetrate deeper and deeper.

Arthur was moaning, his back arching occasionally as he played with his

nipples. The last couple of dates, Karim had spent ten to fifteen minutes

just eating out Arthur's hole, until it was practically begging to be

fucked. But tonight he couldn't wait.

He crawled up over Arthur's body, licking the sweat off his abs, his

nipples, his pits, before coming in for a kiss. Karim's experienced cock

was already aimed straight at Arthur's opening, Karim confident that his

spit and copious precum would be enough.

Without a word, the head of Karim's cock pushed inside Arthur, who arched

his back with that initial shock that bottoms learn to love. He had been

fucked by Karim before, and each time just got better, as his hole got more

used to the intrusion. Arthur had to admit, he'd taken bigger cocks before

(much bigger, Arthur had a bit of a size queen phase), but none of them hit

his joy spot like Karim's. Maybe it was just because of the shape of

Karim's cock, maybe it was because Karim wanted his bottoms to enjoy being

fucked as much as he enjoyed fucking them. Either way, in this moment

Arthur was seeing stars.

Balls deep, Karim gave Arthur a few seconds to adjust, before beginning to

thrust. He was a sensuous lover, adjusting and readjusting his thrusts to

elicit the most torturous of moans from Arthur, who lay panting sweaty

beneath him, gasping and making high-pitched whines every other thrust.

Arthur was fully rock hard, and it was only a few minutes into the fuck

that he started to whimper uncontrollably.

"I'm going to, ah, uh fuck me baby, fuck me, I'm, fuck--" Arthur screamed,

his untouched cock shooting short bursts of cum over his furry abs. It

soaked into the hair, though Arthur swiped a finger through it to give

Karim a taste. "Look what you made me do," he said with a wink.

"I can finish quick," Karim said, but Arthur interrupted,

"No babe, I can go for a second round. At least." Karim grinned, taking

that as a sign to redouble his efforts. Sure enough, Arthur stayed hard,

his cock head dripping both cum and precum onto his happy trail.

For a few minutes, Karim allowed himself to be a little selfish. He focused

on his own pleasure, really ramming his cock into the grunting man beneath

him, reveling in the tight, velvet glove wrapped around his throbbing cock.

Each exhalation from Arthur made him feel strong, like a bigger man, and he

admired his own arms as he fucked, each one planted like pillars beside his

partner's head. He flexed surreptitiously, his own cock flexing too inside

Arthur's rectum. Arthur letting out a moan of pleasure, almost swearing

that he could see his abs push out with the flex of that beautiful man meat.

The clenching around Karim's dick was beginning to become too much, and he

picked up the pace. Sweat dripped from his body onto Arthur's as he rammed

his cock into the other man's hole, both grunting like primal cavemen.

Karim's arms wrapped around Arthur's back, pulling the two bodies close,

and Arthur's back arched involuntarily as his untouched cock suddenly

rubbed against the sweat-slicked sixpack above him.

Arthur's cock, rubbed perfectly down the crease in Karim's abdominals,

began shooting once more, spraying up between both bodies and splattering

on the lower one. The uncontrollable anal clenching set Karim off too,

though he tried to hold it back, and before he could stop himself he was

bellowing as he got his own nut.

He could feel the walls of Arthur's ass get slicker as he sprayed his load

deep inside his guts. Arthur could feel it too, heating up his insides.

Though he, like many bottoms, imagined that they could actually feel the

cum spurting inside them, this time he really could feel each individual

jet, like hot spurts of molten gold shooting inside his body.

As Karim came down from his orgasm, his muscular, sweaty body slowly

collapsed onto Arthur, who felt an intense heat from his gut. A moment

before it became unbearable, it stopped, dissipating throughout his body,

leaving him with a warm buzzing feeling as though he had just taken a shot

of whiskey.

Karim, never one to rest for too long, hauled himself up, his semi-hard

cock slipping out of Arthur's hole with a pop. "Let's see how it worked,"

he said, gripping Arthur's wrist and pulling him out of bed.

Waddling to the bathroom, Arthur reached back and fingered his hole. Karim

had launched that load in him deep, and it didn't feel like any was

slipping out of him.

"Time for the moment of truth," he said, stepping on the scale. After a few

seconds of stabilization, a number appeared. "One fifty three."

"Told you," Karim said with a wink as he leaned against the doorframe.

"Hey, for all we know, the extra weight could've come from the gallon of

cum you dumped in me!" Arthur said, though as he did he couldn't help but

feel up his biceps. They did seem a little bigger.

"How's that pound of muscle feel on you," Karim asked. Arthur checked his

body out in the mirror. He didn't see too much of a noticeable change. He

still definitely looked like him. But it did seem as though he had a bit of

pump to his muscle, as though he had just worked out. Though after that

fuck, he may as well have.

"And how'd you like another pound?"

*-* * -**

The third fuck of the night ended with Arthur kneeling on the couch,

bracing himself on the backrest as Karim slammed his fourth load of the

night into Arthur's wrecked ass. Arthur hadn't even gotten hard during this

fuck, but he moaned all the same as Karim turned his hole to mush.

Standing on the scale after, he admired Karim's handiwork. One hundred and

fifty six pounds didn't seem like he had come that far, but he definitely

noticed it. He felt stronger than ever, despite having just been cored out

like the sluttiest of twinks, and even his hole felt stronger as he

clenched it shut, not letting a single drop of Karim's virility spill out

of him.

That night, the two of them cuddled together, the sheets thrown to the

floor. Arthur had all the warmth he had from his own furry body, Karim's

sweaty body wrapped around his, and the load of muscle-growth cum still

burning its way through his veins. As he closed his eyes, he felt Karim's

cock poke around at his loosened hole, and as he drifted to sleep he

thought to himself.

`I could get use to dating a metabreeder.'
