Gas Leak
Four days into their stay at their Airbnb, John and Tim get the evacuation notice. Apparently, some company has accidentally had some experimental gas leak into the surrounding areas. They were supposed to be here for a week, a much needed vacation from their lives. Tim getting over a rough breakup with his boyfriend and John just needing a break from his horrendous corporate job.
After getting the email, John gets a text from Tim, who's out buying groceries for the big dinner they were planning on cooking together. They've been friends for so long. John having a debilitating crush on Tim but Tim has made it clear that he doesn't want to ruin their friendship. Considerate but it still hurts when people think they're a couple and Tim has to clarify that they're just friends.
The nearest grocery store is around 5 miles away. John cannot imagine the traffic. A ten minute drive probably doubled.
John: Be safe! Do you have a mask in the car?
Tim: yeah make sure all the windows are closed. I'll be back as soon as I can.
John's in his pajamas - just a T-shirt and boxers - and his bathrobe. According to the email, the gas smells musky, and is not "contagious" as far as the company is aware. Which is strange enough to make John wonder what this company was making. He's never even heard of it and a bunch of Google searches yields nothing. He starts in the living room and makes sure the glass door to the pool is shut tight, the front door and windows. Then into the kitchen/dining room. Down the hall into the bathroom where a small window in the shower is closed tightly.
On his way to Tim's bedroom, he pauses. Takes a good long whiff. It's like a locker room has suddenly appeared in the bedroom and a bunch of hot sweaty men are in there post-workout.
Oh no.
Covering his mouth with his shirt, he runs down the hall to find the open window in Tim's room. The smell is so overwhelming it seeps through his shirt and makes him cough. He shuts the window and locks it, makes sure it's completely sealed as the gas, almost like a fog rolling off a lake, goes into John's lungs and fills the small bedroom. His heart pounds as he takes his phone out of his pockets with shaky hands, desperately searching for the evacuation email for a phone number, a website, any kind of instructions on what to do if you accidentally inhale the gas.
But there's nothing.
Doesn't help either that his hands are burning, a pleasant tingly burn that makes his heart thud harder, makes him take deeper breaths and inhale more of the gas, and makes him notice that his hands are, in fact, growing. Blood slowly pumps into his cock as he holds a hand to his face and watches as his fingers stretch and expand, the palms inflating and fattening, wrists widening. The growth is slow and feels so good. All these bones and muscles growing and rearranging should be painful, but instead, it makes his cock rigid, harder than it's ever been in his life, as he drops his phone on the floor. He holds both of his hands in front of his face as they grow into huge, meaty paws. Big hands with thick fingers, the kind of hands attached to jocks or bodybuilders. He also sees that they're darkening, becoming tan. No not tanned, this looks like a new skin color overtaking his pale skin. The burn goes away and he's left staring at this massive hands, with a hard cock pressing against his boxers.
He makes a fist with his hands and moans, the action sending pure sex to his cock, which feels much more sensitive than it used to. He uncurls his fingers - fuck, fuck, fuck - as he grabs his phone. He tries using his fingerprint but the phone doesn't recognize it. Panicking, he stumbles out into the hallway as his cock heaves forward, like it's trying to fuck something, as his feet start burning. He trips over them and lands on his sensitive, bigger hands as he feels his toes and feet start thickening and growing and putting immense strain on his socks. He hugs his stomach as a bunch of horny butterflies just settle there as his feet stretch and grow, ripping right through his socks as his darker toes poke through, the soles widening and filling with strong, lithe muscle and veins. He tries his hardest to suppress the loud moans he wants to make, instead covering his mouth with his big hands and whimpering into the palms as he lies on the floor, his feet pushing into double digit territory. He looks like a freak, with massive hands and size 14 feet attached to unremarkable arms and legs, both two shades darker than the rest of his body.
A huge wet spot forms on the front of his boxers as a loud, sighing moan escapes his lips.
He's never cum hands free before.
His cock pulses and the swollen head rubs against the fabric in such a way that it makes his legs shake, trembling as it feels like his cock is getting an expert handjob. But it's still rock hard, as if he hadn't just cum, as he stands and staggers on his bigger feet into the kitchen. He pants, sweat starting to drip down his face, as he leans onto the counter and tries unlocking his phone. His nipples tighten and then harden against his white T-shirt, now being stained with the sweat pouring out of his body. Fuck he can smell himself. He's starting to smell like the gas. This thick, musky, gym rat funk that he, unathletic him, is starting to produce. With his phone in one hand, he brings the other, trembling hand to a nipple which is so hard, harder than he's ever known his nipples to get. The moment his hand touches his nipple, he moans like he's getting fucked and his knees buckle, the sensation so overwhelming he's cumming again, soaking through his boxers. His hand spasms and he throws his phone into the living room.
John crawls to the living room, leaving a snail trail of musky cum into the living room. The pleasure is so overwhelming he can't think straight, crawling on his elbows as the dark tan races up his hands and into his forearms, that pleasurable burn causing his forearms to bloat and expand. Dark hair bursts from his pores as he collapses - face down, ass up - as he squeezes his eyes shut, silently pleading for it to stop as his biceps start expanding and straining his sleeves. His overheating forehead feels incredible on the cold tile as he flexes involuntarily as his biceps split the sleeves, his shoulders widening and tearing through his soaked T-shirt. His eyes pop open as he can feel his pit hairs become denser, thicker and darker, damp with sweat with powerful musk radiating through the widening tear of his bloating biceps, muscular shoulders pressing against the soft robe and making him hump the air once as another orgasm rips through him. He leans against the couch as he flexes his bicep and moans at the huge peak splitting the rest of his sleeves, the huge muscle exposed to the air as well as the jungle of his pit hairs.
Panting, sweaty, cock steel hard and a hormonal fog smothering his brain, John grabs his phone and calls Tim. He rubs his stomach as he feels his soft gut gurgle and twitch, the fat underneath his hand squirming and preparing for something. He goes cross-eyed at the sensation as his cock jumps in his boxers.
"John, holy shit you won't believe it! I don't know what this gas is doing but it's making dudes jerk off in the store and fuck each other! The cashier who checked me out was getting absolutely railed."
"Tim.."
He feels his gut implode as the fat in his stomach suddenly shifts in two directions. First up into his flat, slightly pudgy chest, and then down into his flat ass. His ass cheeks stretch and inflate, as a few pounds of fat land squarely in them. Both sensations make him throw his head back against the couch and moan, literally screaming in pleasure as he starts grinding his bigger, plushier ass on the floor, the tightness of his boxers intensifying the pleasure.
"John!?"
"I - I inhaled - pant - inhaled some of the gas."
His pecs swell behind his swollen nipples, splitting his shirt right down the middle. Hairy, muscular cleavage exposed as the dark color spreads through his pecs, bloating them with muscle and fat. It spreads to his neck and he can feel his Adam's apple inflate into a huge knob in his neck, throat widening and expanding.
"Your - your window was open. Aw FUCK."
His voice is so deep, so sexy. A hint of a Greek accent comes through and textures his words.
"John!? What's happening to you!?"
His pecs inflate with muscle and fat, nipples spreading and just dragging against the damp fabric making him moan and groan as they keep growing. A pair of huge, muscular tits that belong to him and him alone. He doesn't really have it in him to explain what's happening. Because he's so horny and also because his brain feels so sluggish, the panic and fear he felt earlier slowly receding as his pecs give a final lurch and form an enviable shelf above his now flat stomach. The top of his tit-flesh presses against his robe and it feels so good. He needs a pair of hands worshiping and squeezing these muscles. Yeah, that's all he needs. A nice cute bottom to suck his cock, give up their ass to him, worship his sweaty hairy muscles. Those beautiful pecs, suck on his greedy nipples.
His back expands and stretches, shredding his shirt as dense muscle packs into his torso. He takes his big, strong hands and rips his shirt off as he feels hair grow on his stomach, connecting to the growing bush of musky pubes above his cock. He looks down and sees his expanding abs punching through his skin, tightening and flexing as his waist and hips widen, snapping the waistband of his boxers. He can feel a brief moment of clarity claw its way through the horny fog in his mind as another few shots of cum exit his cock.
"Tim, Tim, don't - MMPH - don't come back."
"I'm not going to leave you here!"
"Tim this isn't a- FUCK!" An Adonis belt goes straight to his hard, trembling, oozing cock. A thick 8-pack carves through his hairy, sweaty tanned skin, as he rubs his hands up and down his washboard abs, feeling the little bit of unburned fat softening them. The strength of his core is so erotic, so intoxicating. Fuck how many sit-ups can he do? "I don't - I don't think I'm gonna be here much longer."
His face tickles as his lips expand into kissable, plump lips and a beard grows across his jaw. It's thick and dense, covering his chiseling jaw, the model-worthy cheekbones.
"I'm hanging up. I'll be there soon! Hang on!"
But John - John? - really can't.
Not when he doesn't even remember his own name.
The deep skin tone spreads to his lower body, and he groans as his ass inflates even more, his hole spasming and becoming so sensitive it makes him fall onto his back, writhing as his ass rips through the back of his tight boxers. The cheeks bloat with pounds and pounds of muscle and fat, the weight hanging off his lower back and jiggling, the plush ass pressing against the cool tiles and relieving the pressure on his hot bulge. He rips his boxers off and lets his soft, muscular bubble butt inflate and drag on the floor as his cock slaps his lower abs, the big pink head oozing pre onto his hairy abs and thick pubes. He grabs fistfuls of his ass and feels the flesh spill through his hands, thick fingers teasing his sensitive hole. His fat ass jiggles as he thrusts into the air, moaning in his sexy voice, as his hair grows thick and lush.
He closes his eyes and feels himself melt, going all the way down to his balls which bloat and grow, swelling into massive golf balls as his cum churns in his fat balls. His thighs grow, inflating into thick pillars of hairy flesh as the dark skin inflates his calves, spreading hair everywhere. His thick thighs grow with muscle and fat, pressing into his balls and forcing them forward. They're so hot, so full. The load he's about to dump will be huge, and after that...he will be gone. With each pulsating wave of growth across his thighs, his hips push wider as his ass grows bigger to make his thighs work to carry the fat, swaying masses of flesh on his lower back. He rubs his thighs, flexing and squeezing the muscles, feeling how thick and strong they are.
He oozes sex and unbridled hormones. He could fuck a man into next year, leave them a whimpering, cum-filled mess in his big arms. Or a guy could get lost in his hole, that soft ass of his.
He lets go of his thighs and flexes his biceps, exposing his musky pits as the dark color finally begins spreading along his below-average - below-average? that can't be right - cock and making it jump and twitch and slap his abs. He feels his cock pump and pulse harder, so much blood pouring into it he feels lightheaded. The old him leaks through his cock and coats his pubes and hairy abs, musky and thick. He gathers some on his fingers, careful not to touch his swelling sensitive cockhead, and tastes himself.
Fuck I taste good.
He sucks his fingers like he's sucking a cock. His own cock stretching into above average territory, but not the overblown man-meat he's going to possess. The edging he's going through as his cock stretches and grows, extending towards his belly button, blows out whatever brain cells he has left. Whatever brain cells that are not totally devoted to getting off, lifting, and simple survival are destroyed as his still growing cock cums like a broken dam. He blacks out, shutting his eyes and feeling like he's falling, tumbling into his fat balls and then firing out of his massive cock. It's a cock built for fucking. It cruises past 8 inches into 9 inches with no problem, thickening as he continues to erupt. The sheer amount of cum is staggering. Thick. Musky. So manly. So strong.
After what feels like an hour, his cock finally stops shooting at 9.5 inches. Out of breath and smelling like he's just gotten back from the gym, he rubs his sticky, cum covered body. A few more burps of cum exit his cock, and along with it, any of his old worries and fears.
Jace opens his eyes as his phone pings.
He doesn't recognize the man texting him but he can imagine the man's - Tim, is his name apparently - fat bubble butt just from the contact photo. Tim is apparently almost there, and asking for some guy named Jason.
In the driveway, Tim tries to will his sudden boner down. He looks down and sees his cock pulsing and throbbing. It started when he looked at the video this guy named Jace, apparently who John turned into, sent him using John's phone. The guy looks a little like John but 10 years older. John was already handsome, but now? He's model-level gorgeous.
He shifts in his seat and his eyes widen as he hears a tear. He gets out of the car and notices his ass has swollen to such an immense size it's torn through his sweatpants. It's so big and meaty, sticking out a full ninety degrees from his back. He's underwear tears off as his thighs thicken in proportion to his meaty ass.
He looks down at the message John - Jace - sent him.
After I fuck that fat ass of yours, we can look for your friend.
He feels a momentary stab of grief at the loss of his friend. John's not dead but he's definitely not here.
But still.....
Tim rubs his swollen ass, bites his lip to suppress a horny moan and looks at the front door of the Airbnb they'd rented. He briefly thinks back to the cashier getting his back blown out by one of the hottest men he'd ever seen.
The door opens and Jace appears, leaning against the doorframe in John's robe, rock hard cock pointing right at him. He looks to be in his early thirties, still short but stacked now, thick and built with muscle. Jace smiles. It makes his whole face light up.
Tim blushes, feels his own cock make an obvious imprint on his sweats.
"Are you Tim?"
There's nothing left of John in there. He wonders if John would even care.
"Yes," Tim says, "I am."
Jace steps out, barefoot and smelling of pure musk, and closes the distance. Jace kisses Tim like he's never been kissed before. Beard scratching his face, plump lips, the right amount of tongue. He's so hard he thinks he might cum right in his sweats in the driveway, just from kissing. He grabs Jace's own huge, soft bubble butt and squeezes, making him moan into Tim's mouth.
Judging by the way Jace manhandles and kneads his fat cheeks, the way his cock pushes out so much pre it puddles on the stone drive, Tim knows that once this man gets him in that house, he's going to get fucked senseless.
Tim came here with the old Jace to get over his breakup.
And it looks like the new Jace - breaking the kiss and looking at Tim with dopey, horny eyes - will be just what the doctor ordered.
