Jaxy Syndrome
🕑 Added 2023-06-11 21:16:08 +0000 UTCJack Maraja snorted herself awake, nose stinging and throat claggy as always. She had to have the worst roommate in the world. It wasn't conscious cruelty - Jack wasn't even sure Roxy knew she existed, sometimes - it was just that the bitch was oblivious... and BIG. Her physicals didn't report anything unusual. She wasn't on drugs. Her parents didn't have a bit of the same traits...
No. Roxanne Coetzee had just showed up to college at the age of 18 as an eight foot tall, curvy Hyena shemale with a fat 12 inch cock and proceeded to quite literally dick around for six years, finally on course to leave the university with her bachelor's degree... as a TWELVE foot tall shemale with a monstrous TWENTY inch cock.
Sometimes Jack swore she could HEAR her roommate growing.
Jack, on the other hand, had shown up as a lanky, six foot shark girl proud of her height... and was STILL a lanky, six foot shark girl because normal people did not grow constantly and arbitrarily.
She -was- about to be a doctor, though, so that was nice. Her roommate had even provided a nice topic for her dissertation, studying the biological and genetic cause of sheer size in real time. Jack was even grateful for that part!
Having to sleep in a literal cloud of musk every night... that not so much.
Said musk’s supplier was laying on her bunk across the room from Jack and snored, each snore loud enough to almost shake the windows- her footpaws hanging off the end of the bed and her shorts bunched around the immense morning wood that reached up against her own stomach, the waistband barely holding it there. To most it was also a stretch to call it morning wood, she had slept in until 10am, after being out partying all night and adding the smell of cheap booze to the dorm.
Roxy was massive, saying she was 12' tall didn’t capture the whole picture if you stopped to consider just how big the rest of her was. Most of the time, she didn't even need to try to bully Jack; just being in her presence was enough to be uncomfortable. Roxy's body heat was such that the room was always sweltering, and her musk coated everything in her scent. When she was actively trying to tease the cute shark? That just made it worse.
She was clearly planning to skip class today, despite being two years behind already. The snores were dotted with bouts of sleep-cackling, in that horrible hyena fashion, as drool oozed from her agape maw.
Wait a minute.. If Roxy slept in, that means Jack slept in too! It's already 10am!
"GOD FUCKING DAMNIT." Jack swore as she hopped out of bed, frantically looking around. Roxy had kept her up long into the night, fucking the girls in the room next door until 11 pm... then breaking for fifteen minutes and fucking the two in the room on the OTHER side until 2 am! Why did she have to do it on their block TONIGHT of all nights. She had an experiment in the lab!
The shark girl grabbed her main lab-coat... only to find it soaking wet with sweat.
Not her sweat either.
She growled, checking in the closet... only for the door to knock her on the chin as the entire closet was filled up with a used condom bloated to the size of a beanbag chair.
There was no time. Underpants or not, an explosion would be far, FAR worse than indecent exposure. Jack moved to dash out of the room clad in nothing but her nightclothes, visibly frantic.
Roxanne had jolted awake at Jack’s shout. "Huh? Is there a fire?" she said as she rolled over, letting her dong flop heavily across the side of the bed and splatter pre across the floor. "What's the rush?" Of course Roxy didn't really care either way, yawning and stretching as her roommate scrambled. One of the many roles Roxy played with her paramores was "Scientist" which meant stealing Jack's clothes and wearing them while fucking their neighbors into submission- and last night that's just what she did! Jack wasn't the only one kept awake, you could probably hear her from three stories up. Which meant at least Jack would have a clear shot if she could get out of her room.
"Heeey, where are you going? Can I come?" Roxy isn't even close to decent yet, bare save her shorts.
"No, shut up," Jack made it out the door before the giant hyena could block her, rushing downstairs and off to the biomaterials lab. Jack's current theory was that her roommate's secret was in the form of a short-lived radioactive pseudo-protein that underpinned her soft-tissues. It would explain everything. If her cells were primarily comprised of a material capable of hyper-efficient energy extraction in seeming defiance of the square cube law, was inherently super flexible and stretchy, but rapidly destabilized and had to be replaced, it would come as close to anything could to explain all of... THAT... that she was leaving behind.
INCLUDING why nobody else believed her. The proteins and even the molecules that made them up decayed outside of Roxy's body. They needed incredibly precise conditions to germinate. Conditions that Jack had finally gotten set up in the lab. Conditions that would not last much longer!
Roxanne cackled loudly, sitting up in bed now and grinning with her big sharp teeth, "Hey~! You can't leave yet, you haven't even helped me with my morning routine!" that meant a handjob, which Roxy insisted on every morning when she woke up (though didn't always get, like today). Waving and scoffing as the shark ran away in her nightie.
Jack skidded to a halt at the door to the lab, frantically shoving her keycard in and stepping inside, seeing several red warning lights on the incubator she was using along with a literal mound of data on the floor. She swore again, rushing to the chamber and unlatching it, tearing it open...
It had been… more than easy to get the genetic material to analyze. Roxy didn’t particularly care why she was growing and didn’t intend to stop, but had no problem with Jack doing research, and even less problem with people running off with some of her cum. The blood was trickier, the hyena practically healed AROUND needles, but Jack had her ways.
When Jack entered the lab and opened the incubation chamber, she could see the rack of vials shaking. One of them had already popped and spilled out, a couple more looked filled to bursting, their contents expanding rapidly. Worst of all, though, was the one Jack had thought most promising, it was glowing red hot from its secure position in the center.
Suddenly, Jack's ears were ringing and the incubator looked rather far up. In fact, her hand wasn't on the release lever at all. Instead she was quite a few feet back from where she should be. And on the ground by the looks of it.
"Huh, that's funny." Jack looked down at herself. Where was her labcoat? Where was her safety gear? ...Oh right, she'd lost it to a giant hyena. Well it probably wasn't that important. The gaping hole in her stomach didn't really seem to hurt much.
...Hmm, she didn't think she was supposed to have one of those. She pushed a claw to her stomach, trying to hold the blood in. It worked perfectly! All her blood went right back inside and her stomach sealed right up. Man, this was the most convenient thing to happen in months.
...Although that was weird, too. Convenient things didn't USUALLY happen to her. Although maybe they would now.
Jack rose to her feet, feeling a brief sense of vertigo that quickly passed as she looked down on the incubator. The interior was pink and torn open, the mechanical innards completely destroyed, nothing but a few clumps of rapidly disintegrating flesh inside it. It had even shrunk at some point! It's spot on the counter closer to waist height than chest height.
Jack looked around the lab, aside from her exploded corner, everything SEEMED fine. Her underpants were on the floor, and picking them up quickly revealed that they'd shrunk from the heat. There was no way she could get an A-cup bra built for a child's frame around her DD-cup chest, and she wasn't even sure why she'd tried shoving her cock in such tiny panties anyway.
...Wait.
Roxy entered the lab a few minutes later, yawning and calling out, " Hey Jack! You forgot your labcoat~" She had brought along the sweat stained garment and held it out as she pushed through (and ducked under) the laboratory door. Her usual cackling subsided as she looked at the mess. "Wow, you really fucked this place up! Isn't that going to... Like... Cost a lot? Man they might even kick you out for this." She walked right up to Jack... And noticed she doesn't quite need to look down at her! "Hey, did you get your hair done?" And Roxy swung a paw to smack the shark on the butt.
Jack ran a hand through her hair as her ass let out a deafening 'Clap' from the massive hyena's hand hitting cake that definitely wasn't there that morning, the messy red waves were about as fluffy as they always were, them and the glasses the only thing that hadn't changed, "Nah, I just grew a whole bunch."
Jack answered, grabbing Roxy's wrist firmly and prying it off her ass... before clapping the hyena's own cheeks, enjoying having them at perfect hand height, suddenly. Jack actually found herself with surprisingly few questions, looking Roxy in the eye for the first time. She'd certainly work out the specifics of what happened later, for science, of course, but right now she was dealing with a perfect explanation for Roxy's behavior up until now.
Roxy's body - and now her body too, as far as she could tell - were biologically incapable of feeling stress.
"So now that I've had a big breakthrough, I was thinking of calling this body-type 'Jaxy Syndrome', what do you think?"
“Ooh!” Roxy jumped as her thick furred butt was clapped. Her rod almost snaped the waistband of her shorts, standing tall in front of her roomate. "You know, I don't think someone who "had a big breakthrough" and "Grew a whole bunch" but still isn't taller than me should be in charge of naming it. How about "Big but not as big as Roxy syndrome?"” She cackles loudly, almost leaning over with the effort of laughing as she holds onto Jack's shoulder and shakes her.
"Well, now that you're as big as me, what are you going to do? Write some paper about it?" She said grinning at her roomate.
"I -discovered- it and did the research. Technically I don't even have to include you. I could just call 'em Jackmazons." Jack stuck her tongue out at the laughing hyena, swatting her with a tail. "But nah, not immediately. I figured first I could fuck a few dozen girls, go to the gym and kinda informally figure out what my abilities are, and THEN do the documentation later."
Jack was getting hard as well, her own cock peach colored and veinier than the hyena's, but just as big, and it just felt natural to dip a hand to it, stroking it as she talked. "Actually -first- thing might be getting a plus-sized desk I can hide people under."
Roxanne cackled, and slid to stand side-to-side with Jack, pressing their cocks together so she could try and get the shark’s hand around both of them. Roxy lended her own hand too, stroking as thick ropes of pre start to splatter to the messy lab floor. "Oh? Going to start your career as a sex-fiend like me? What about your dissertation?" The shark wasn't exactly a prude, but she never was this overt about sex.
"Still finishing it! Might make it short though. "Dear review committee, you can see by the enclosed pinups that I grew to 10 times my size and 100 times my beauty. First person to make me a doctor gets to learn how. Okay go." Something like that! Really turn it around on 'em." Jack snickered, joining the fun, pressing her balls into her roommates and breathing deep, loving the scent of her OWN musk being noticeable over the hyena's usual cloud. "It's not 'sex-fiend' if they're all eager and I still do other things."
Roxy rocked her hips back and forth, she could feel her balls growling and churning with production. "Ten times? That’s just bullshit, unless you're planning on getting even bigger somehow." She cackled, "I haven't had a growth spurt in a few months, remember." Roxy gave Jack another heavy spank on the butt and let out a howl as she peaks! Thick heavy ropes of dense hyena-seed rocket across the lab and coat someone else's experiments, the musk only increasing as that boiling hot load pours from her heavy balls. So stringy and potent.
"No, see, this is why you had to leave the math classes, if I -double- in height, that's an inherent eight times bigger I am," Jack smirked as she explained, "Since we're three dimensional. If I double in one dimension but stay even, I actually get multiplied by 2^3, which is eight." Jack gripped the base of her own cock, licking off the thick yeen cum coating her, how had she never realized how delicious it was? "But I -didn't- keep the same proportions. I added a whole lot of curves,"
Jack shook her hips, an ass almost twice the size of her waist jiggling beneath her, "A whole lot of MUSCLE," Jack flexed her stomach, the outline of abs appearing across her as she tightened, "And a whole lot of... well... THIS!"
Jack came as well, a thick, white GEYSER rocketing into the ceiling and splattering down over everything, sprinkling over Roxanne's own load as fifty gallons of musky, STEAMING pudding quickly became a hundred.
"So really, ten is a conservative estimate, especially if -I- have a growth spurt before I meet them~"
Roxy rolls her eyes and cackled, "Jackie, no one gives a shit about volume, it's all about height and stuff, don't be a nerd." She pats her butt again. Of course both of them were still hard, and so Roxy just began to stroke again! Their cum-soaked cocks grinding against each other, each immense cock already throbbing back into hardness. Another change, just like the hyena, the shark had better get used to never being empty. She could just go and go and go! Roxy was quite aggressive with her stroking- but now that Jack was the same size as her, it wasn't so... Rough!
"Oh my god," Jack deadpanned, rolling her eyes as she circled around to get out of masturbation range for round two... before raising a leg and planting her clawed foot firmly on Roxy's ass, "Y'know what? I know you don't mean it. I've caught a bad case of empathy here. You really can't help the years of bullying, being the planet's shittiest roommate. It MIGHT even come as news to you. I woke up this morning half-hating you."
Jack pushed the hyena to the floor, knocking her over, ass pointed in the air, "But I don't have that malice in me anymore. And I realize that your issue is you've never needed to learn. Not ONE authority has ever been able to pound some manners into you."
Jack leaned against her roomie, throbbing shark-cock lining up with her backdoor, pouring pre down her legs. "So I'll be the authority, and this will be the pounding."
Roxy let out an oof as she fell to the floor, her thick fluffy butt pressed into the air! "Hey~! If you didn't like me, why did you keep giving me all those handjobs?" She said punctuated by a still confident cackle as she swished her tail around, heavy chest smushed to either side of her torso and visible from behind. "You think you have what it takes? I've had every guy in the dorm fuck me and none can keep up~ How about a wager? If you can't fuck me senseless before lunch I get to show you how it's done~" She reached back, and spread her own cheeks. Even as thick shark pre began matting her fur.
"YOU GOING OFF IN MY LAP AFTER COCK-SLAPPING MY PALM IS NOT A HAND JOB!!!" Jack may not have been capable of anger anymore... but she was definitely capable of yelling, giving the Hyena a strong dressing down as she shoved her cock inside. Unfortunately, the hyper hyena really had bitten off quite a bit more than she could chew. There were WORLDS of difference between taking an eight inch cock and taking a 20 inch one. And, for that matter, entire universes between a guy intimidated and impressed by you trying to pleasure you... and a monster shemale with encyclopedic knowledge of the human body targeting your prostate for a seek and destroy.
As Jack slammed forward and sunk all 20 inches inside, Roxy yelped and arched hard as the shark's fat tip glanced off her prostate. Her own immense dong throbbing and rocketing a jet of pre across the floor, splattering it into the underside of her own chest! "Y..yeah! That's it! And it totally does count, you just pretended not to.. Nnh!" she forced out even as her toes curled on reflex. Pressing back against Jack as they start to fuck right in the middle lab on the floor, just as some people try to enter, though they only see the pair for a moment before their goggles fog up and they flee.
"Cumming because -your pheromones- are a bigger part of the atmosphere than carbon dioxide is NOT the same thing as a sexual encounter," Jack gestured at the pair of scientists running off from the pair of hyper-futas, their faces already flushed and leaving a trail behind them as they came in their pants. "Otherwise those two idiots would both count as sexual partners. If sexual stimulation was love, then that'd mean once I plow your brains out you'd have to marry me," Jack scoffed, reaching around and groping Roxy's massive balls even as she bottomed out again and again, ruthlessly overwhelming the giant with sensations her body thought it could only give, not receive.
Roxy finds the time to cackle, even as she goes cross eyed and starts to pour out vile hyena -seed across the floor~ her heavy balls tensing and growling as they're groped. "Nnh.. G..got a ring saved up somewhere, nerd girl? You.. Ah.. don't have as much experience as me.. I'm.. nNnhh.. Gonna make you beg me to marry you." The constant assault against her prostate made the huge hyena twitch and tense, she was already getting close. Jack had her work cut out for her! It was going to take more than one forced climax to break in her big belligerent roomie.
"The thing about experience is - it only really counts if you practice EFFECTIVELY," Jack leaned in, biting Roxy's shoulder, teasing her neck with her teeth as the shemale instantly recovered from her orgasm... only to IMMEDIATELY start in on another, soaking her own front as Jack remembered the sweet spot and treated it mercilessly, pressing, sliding, twisting, motion in every sort with superhuman force on her most sensitive spots. "That's why I'm about to be a doctor, and you're about to be my bitch."
Roxy moaned, drooling with her mouth agape from the pleasure. "Nnh.. you.. you call this a rutting? Harder you nerd~ I can't feel it yet." She said moments before erupting a second time as her prostate is railed over and over, rocketing hundreds more gallons across the floor as the lab starts to flood. By now musk was starting to fill other nearby areas of the building. Each moment Roxy was getting more and more worn down, her resistances failing as her body reacted more intensely to each rut.
"Oh no you poor thing!" Jack gasped in fake horror, adding her tail to the routine, grappling Roxy's cock and controlling her output, forcing the hyena to get backed up, release, and paint herself thoroughly in a vicious cycle as the proverbial sea of seed climbed higher. "All that cum and you don't even feel ANY sexual pleasure! I'd better fuck you HARDER." Jack slammed into the floor, shaking the building as her balls clapped against Roxy's, "LONGER." The yeen unloaded again, digging through the concrete floor with the force of her stream. "Better. I'll have to lead by example, show you what it's like to have somebody with some control, somebody just... better."
Roxy squeezed hard around her cock, the hyena in a state of near constant orgasm, her balls don't never even gettting close to being empty! "You study this sp..speech before starting? W..when are you going to fill my ass, nerd?" She howled out as she climaxed again, rolling to her side and lifting one leg, thrusting into Jackie's tail as she was ruined! Her poor prostate is going to be bruised at this rate!
"You don't get a drop of MY cum until you're done spilling all that inferior garbage," Jack leaned in, still teasing her toy. "It's hardly MY fault that we both have eight times the neurons of a normal person and I'm the only one who knows enough about Metcalfe's Law to see the possibilities there. But that's why I'm doing this. To teach."
Jack punctuated another nerdy taunt by leaving a crater in the laboratory floor.
"So beg. Say 'yes, sensei' or 'yes, my goddess'. And beg."
Roxy was cross eyed and moaning, god this felt so good. It was nice to be on the bottom for once, and Jack seemed to be enjoying herself. It was getting harder to think... Maybe she deserved this for teasing the shark for years and years straight, but that's just the name of the game, isn't it? "Sensei? Y..you weeabo-" she choked as more cum got forced out of her, splattering against the far wall as her head got all fuzzy. Man... She has no clue what she's talking about. Metal cafe's law? What's that shit about. "N..No matter how strong you get you won't be able to teach me a thing" She manages before climaxing again, dozens upon dozens of times as she pants like a dog, "God yes, M..Mistress fucking fill.. MMm..Yes...sss~"
"Oh, there's really only one thing you need to learn. Who's in charge?"
"Y..yooouuu!" Roxy howls.
"Good girl~" Jack cooed, pulling the hyena tight as she finally let herself go, the 99% of her brain that had been dedicating to holding back her own orgasm finally relaxing... and letting her paint every inch of the yeen's insides. The first blast of tar-like cum against her prostate was harder than any of the thrusts have been, and Roxy quickly started to BULGE under the massive, gluey load, Jack getting blue balled and pent up in only the half hour they'd been on the ground rutting.
But hey, roommate issues: resolved.
Roxy was sure they will get along fine now, and they can even help each other out every morning. Roxy was a mess, totally bloated out as excessively thick shark-sludge pours out all over the floor! And all she can think is that... Jackie isn't going to stop at only one orgasm, right? Her own cock oozing and spitting seed as her prostate got ruined~ The musk so intense it fogs up windows and beakers all over the lab, almost hard to see!
Jack only had one thought occupying her own mind now.
"God, that is a LOT of cum."
Jack unloaded again into her hyena dump, bloating the shemale into a sphere, her g-spot crushed in constantly by the load of cream-colored tar gumming up her insides.
But she didn't feel any less pent up.
So she withdrew her cock, sat on the floor, floating atop Roxanne's ocean, and bent over to suck her own dick, quickly getting another load out of herself, bloating her own gut wide.
But if anything she felt MORE pent up.
So she stood up, went over to the bio-weave reactor on the far side of the lab, and unloaded into its stores, filling it up in seconds.
She... still felt PRETTY pent up after that. But Roxy could just suck the rest out of her later.
Roxy lay sprawled out on her stomach, excess cum pouring out of her stretched ass as she deflated, "How you feeling doll?" The hyena had quickly regained her senses.. she didn't have much going on in her head, so it was easy to put it back together. "Come over here, you don't look empty yet~" Making a stroking motion in the air. "I'm gonna make sure you don't get sore~ Trust me, I know how this stuff works better than you." She cackled! Nothing had ever made her grow as much as self-sucking did, and if Jack was the same, well, she still had one secret to get one over on the shark with.
"I think we -both- know I'll never be empty again. But we can go back to the room, maybe redecorate a little." Jack turned on the bioreactor after inputting a few details, preparing a surprise for her new pet later.
"Besides, I do believe you lost a bet," Jack swooped up the bloated hyena, carrying her in her arms as she readied to leave the lab, wading through shin-deep nut sludge flooding the entire building, pouring out of the halls. "And I've got a few requests for you~"
Roxy let herself get picked right up, slapping at her tail a few times, "A bet? Did you say what you get if I lose?" The hyena had her tongue hanging lolling out, and her asshole was totally ruined. "What kind of requests? You want me to rail you this time?"
"Haha, you'll see." Jack said as she kicked open the door and left the materials building... only to come face to face with a bit of a surprise LONG before their dorm. The entire building was surrounded by biohazard tape. A plastic quarantine tent had been lowered over the facility. And on the quad outside, there was a dividing line... between an aggressive orgy of pheromone-poisoned students eagerly rutting each other, desperate for relief... and a military unit crouched behind sandbags, pointed right at them.
Jack looked around again, willing herself past the constant haze of dominance in her mind, letting herself really SEE the fact that the air was practically opaque inside the bubble, a building sized-condom with a swamp of jizz constantly lapping at its sides.
"Wow. We -did- make a mess." Jack said finally, taking a deep, very familiar smelling breath as the rifles tracked her. "Y'know what? Actually? I've just got one request."
"Follow my lead."
