"Nyaan, come help me bring this inside!"
Machu's voice leaked through the open windows of their shared abode alongside the summer breeze. Perking up from the couch, Nyaan leaped to her feet, stretching in her typical feline manner. She opened the front door, eager to see her housemate return after an unusually long work day. Machu's shifts in the GQuuuuuuX moving construction equipment very rarely ran over 6 hours, much less today's 8. But as Nyaan caught a glimpse of her red-headed friend, her eyes widened as she soaked in the machine stationed to Machu's left, suddenly understanding her prior call for assistance. Beside Machu sat a treadmill, certainly too large for Machu's lithe frame to move on her own.
"She must have gotten the GQuuuuuuX to bring it this far..." Nyaan reasoned to herself, bracing her arms for some heavy lifting. "Where did you even get that? And why?"
"Oh! You're never gonna believe it!" Machu's overeager voice pitching high. "Went for a dump run to search for some parts, GQuuuuuuX's arm needed a patch-up. But as I was rummaging through the trash I found this! All in one piece! Now all we gotta do is get it inside to see if it really works."
Nyaan hummed in acknowledgement, crouching down to pick the treadmill up from the base, Machu meeting her movements on the other side. On a three count, the duo lifted at once, barely able to keep it aloft. It was heavier than Nyaan had expected, but she could handle the weight well enough. Machu on the other hand struggled, her face turning as red as her hair as she strained to keep her end up. Slowly, the two shuffled through the front door and into the house, navigating around the messy living room and through the tight hallway. Eventually, they decided on placing it down in a side room they had previously set aside as a guest room. The beach house was a three bedroom suite, leaving the excess room in a state of limbo. It had sat mostly vacant for months, Nyaan satisfied that it was finally seeing some use. The treadmill hit the ground with a skull-rattling thud, akin to a Mobile Suit's foot making landfall.
"Damn, sorry 'bout that Nyaan. If I held that thing for another second my back was gonna split in two! Hehe!" Machu laughed it off, and Nyaan joined her. But Nyaan felt a sense of embarrassment in Machu's voice, thinking that this sudden pickup wasn't just out of happenstance. For the year and a half she had known the girl, Machu was always on the frailer side physically. Certainly she was no slouch in her Gundam, but outside of it she was easy to push around. Especially working around a bunch of buffed-up construction men, Nyaan could understand where such an insecurity could take root. Machu moved to the machine's side, taking its cord and finding a nearby outlet.
"Alright, let's see this baby sing!"
Machu plugged the cord into the wall, fingers crossed in anticipation. In an instant, the blackened screen at the top of the treadmill sprang to life, emitting a soft white light. Machu jumped in celebration, excitedly fiddling with the treadmill's settings.
"Let's go! Finally something goes my way!"
Nyaan looked on in mild shock, surprised by just how elated Machu appeared.
"Wow, really looking forward to this huh?"
"Oh Nyaan, like you wouldn't believe! Piloting GQuuuuuuX is fun and all but it's not much physical labor, y'know? And I'm a growing girl, gotta start taking care of my form!"
Nyaan nodded, but in truth she didn't really understand. She thought Machu looked fine, great even, already. Was she really feeling so much pressure to "get swole"?
"Well, if it makes her happy, sure." Nyaan decided, seeing no reason to rain on Machu's parade now. "So, wanna give it a test ride?"
"Nah, I've had about enough for today..." Machu yawned, stretching out her sore back. "Lets just scrounge up some dinner and find something to watch yeah?" She turned towards Nyaan, a knowing smile settling into her face.
"Now that is something I can get behind." Nyaan submitted, more than eager to settle into their usual, comfortable routine.
---
It had been a week since Machu came home with the treadmill, and Nyaan was starting to get sick of it. It was the noise more than anything. Their cozy beach house was made with unfortunately thin walls, meaning Nyaan could hear every stomping footfall Machu made as she ran along its rotating belt. The constant thuds were annoying, but fortunately Nyaan had a pair of cat-ear headphones she was fond of, which helped drown out the noise. Absorbed in her music, Nyaan let out a light yelp as a finger lightly tapped her shoulder. Settling the headphones around her neck, Nyaan looked up to find Machu, sweaty and disgruntled.
"Wanna go out for lunch today? Need a pick me up."
"Uhhhhh sure. But you're probably gonna want to change first."
Machu looked down at herself, realizing she hadn't changed out of her underwear when she began her usual jogging session. Turning beat red, she immediately made a beeline for the changing room. Nyaan sat alone on the couch, the image of Machu, drenched in her own sweat, in nothing but her tight black underwear, filling her mind. Having lived together for so long, Nyaan had of course had the occasional lewd thought of her roommate. But it had never gone beyond a curiosity for Nyaan, a "what if..." thought experiment. But suddenly, as she closed her eyes, Machu was standing right before her again, sweat soaking into deep black fabric. Machu's breasts weren't extraordinary but they were certainly larger than Nyaan's, and god did they look good in that top. Nyaan's mind wandered downward, where Machu's slim hips framed her crotch. Through the fabric, Nyaan could see the outline of Machu's girl cock, momentarily inflamed by the excitement from exercising. At the thought, Nyaan could feel a stirring beneath her tight jeans, her own womanhood thickening at the torrent of Nyaan's fantasies. In a moment of near intoxication, Nyaan's hand moved downward, teasing the flared tip of her unusual member through the rigid denim. But as the sound of Machu's returning footsteps reached her ears, she ceased, quickly hiding her excitement with her hands.
"C'mon, no time to wait, I've worked up a hell of an appetite."
---
Machu fidgeted with her chopsticks, her bowl of ramen sitting uneaten below her. Across the table, Nyaan slurped desperately at her own bowl, devouring it as though it would be taken away from her. A habit that was ingrained in Nyaan many years ago, that never quite left her. Wind picked at Machu's hair, tied back into a small, loose ponytail. The blue was starting to seep back in, she was due for a redye soon. Nyaan momentarily stopped her slurping, looking up at Machu's hooded, forlorn eyes.
"Aren't you gonna eat? You're the one who wanted to go out..."
Machu sighed, entertaining the idea by picking up some noodles with her chopsticks, but not committing to actually taking a bite.
"I dunno, if I'm trying to get in better shape this wicked salty food probably isn't a great choice."
"Oh please." Nyaan scoffed, an uncharacteristic amount of disdain filling her eyes. "As if you're in bad shape. There are girls all over the Earth-sphere who would kill for your figure! A little salt isn't gonna kill you."
Machu retreated a little, not expecting such harsh pushback from her roommate.
"I... I guess so. But I'm so... small! That's the real concern. I still feel like such a kid!"
Nyaan relented at that, suddenly understanding Machu's frustration. Even though they were only 19, they were doing everything they could to feel more like adults. They had their own house, they worked almost full time, they were closer than almost anyone else their age of achieving that elusive adulthood. Nyaan scrunched her eyebrows in thought, considering how best she could support Machu at this moment.
"Well... if the goal is to grow, then I would say the first thing you're gonna want is carbs. And the best way to get carbs? Noodles."
Machu looked down at her then abandoned bowl, a newfound spark of inspiration glinting in her eye. In an instant, Machu was attacking her ramen like a rabid animal, shoveling into her mouth even faster than Nyaan had been prior.
"Woah woah take it easy Machu! You're gonna choke!"
...
In no time at all, the table was adorned with two empty bowls and nothing more. Machu sighed heavily, resting her head against her hand as she lazed for a moment.
"Y'know, this is a good start, but I'm not convinced just eating lots of noodles is gonna be enough."
Nyaan, leaned back in satisfaction, perked her head up, confusion twisting her brow.
"Well, can't just eat noodles of course. If you really wanna go all out with this workout you're gonna want a lot of different nutrients and stuff. Like, a bodybuilders diet or something I don't know."
"I'm not trying to bodybuild!" Machu retorted, a smile tugging at her lips, betraying her faux offense. "Just trying to... fill out."
"Alright alright I got the message. But still, a good workout is the food just as much as it is the movement."
Nyaan's gaze began to wander downward, suddenly finding herself gazing at her own shoes. Her voice dropped a brush, reaching a more serious tone.
"Can I... tell a story? It won't be a really happy one, but it'll be worth hearing, I promise."
Machu raised an eyebrow, curious at the sudden change of mood. She knew Nyaan's past wasn't all sunshine and rainbows, but she had always tried to stay open to her feline friend.
"Sure, hit me."
Nyaan hesitated, eyes still stuck on her shoelaces. But she found her voice eventually, raising her head to look at Machu.
"When I was younger, around 11, I had it worse than ever before, or since. That was the time where I was too young to find work, and I couldn't really pay for very much food. I started getting really thin. Like, scary thin. And I thought that I could gain some weight by running more, so I did laps around the block every morning when I woke up. But all that really did was tire me out every day, didn't put on a single pound."
Machu leaned forward, having invested herself in this story so suddenly.
"So what did you do then?"
"Well, I found a corner store that sold a lot of weird stuff. They didn't really sell much food, but they did sell these supplements. Like, nutrient supplements. So I took those every once in a while and got some of my weight back. It was only for a bit before I found some work and made money for real food, but it kept me afloat."
Machu sat in contemplation, understanding the point Nyaan was trying to impart to her.
"Yeah, I can tell why you thought I should hear that. And I hear ya loud and clear, gonna start taking this a little more seriously than just 'running equals good'."
Nyaan smiled, glad she could help her friend, and also silently glad she may not be hearing Machu's thunderous footsteps every night now. The two got up from their seats, moving back into the Ramen shop to return their bowls. But as they exited the store, Machu fell out of step with Nyaan. Nyaan looked back, silently asking Machu what the deal was.
"You go on ahead, I'm gonna run an errand I've been meaning to do while I'm out."
Nyaan considered arguing with Machu, but decided to let it go. She had found that arguing with the redhead was usually a fool's errand anyway.
"Alright, just don't be too long. If you're not back by 6, I'm coming out in the GQuuuuuuX to get you!"
"Will do, don't you worry!"
At that, the two parted ways. Nyaan hoping against all hope that Machu wasn't doing something stupid.
---
"This is stupid." Machu thought to herself, having found herself standing in line alongside the weirdest crop of Earthnoids she had ever seen. The plan was simple enough, if it worked for kid Nyaan it would work for her! So Machu wandered around town until she found a corner store. As it turns out, that type of backdoor retail wasn't particularly popular on earth, with megachains and supermarkets having swallowed almost every store in the suburbs. So Machu has found herself standing outside of what could be generously described as a "metal shack", waiting in line behind a woman who was coughing into some type of apparatus mounted on her shoulder, and in front of a man who looked like he was midway through transforming into a Mobile Suit. After what seemed like an eternity, it was Machu's turn at the window. The clerk inside, who looked like he was ripped straight out of the middle ages, greeted her kindly, his warm voice betraying his sharp exterior.
"And what're you seeking, young lady? Seems like a strange place for a soft thing like you."
Suddenly, any semblance of confidence left in Machu was lost. Her usual righteous anger now replaced by crippling insecurity. She didn't really even know what she wanted, even less so why she decided here would be the best place to get whatever that might be.
"Umm... I... want something to help me... get bigger..." Machu's face was as red as her hair at this point, her words jumbling in her mouth. The clerk raised an eyebrow, a strange request even for a place as bizarre as this.
"Do you mean like, weight gain? Because we can help you with that if that's what you wish."
Machu shook her head furiously, trying desperately to sharpen her mind.
"Nononono! I need like... nutrients. Yeah, nutrients! That's it! I want to look a little bigger like... like an adult y'know! Not like... fat. And I've been working out but it's not really enough and I just need a little outside help. You follow?"
A knowing smile spread across the man's face as he reached behind him to pluck something off of an unseen shelf.
"Ahhhhhh. Yes now I 'follow', you're certainly not alone in that desire. Here, this will do you nicely."
He gingerly placed a large container onto the windowsill, Machu squinting to read the label.
"Enhanced protein powder, one of our most desired items in our catalogue. Just mix in a little with your drink in the morning, and you'll have that adult weight you want in no time."
Machu beamed as she held the powder in her hand, if this dude was really telling the truth this was like mana from heaven! Scrambling for her wallet, she snatched as many bills as she could fit into her fist.
"Name your price, whatever it is I'll take it!
---
Nyaan sat alone on the living room couch, mindlessly scrolling on her phone. Even while colors flashed and words flew by on the screen in front of her, Nyaan's mind was over occupied with thoughts of her roommate. Machu's newfound crusade to fill herself out had sparked something hidden away deep inside Nyaan. Fantasies of her fellow pilot came and went in seconds, each one fulfilling some of Nyaan's deepest subconscious desires. Some were tame, borderline wholesome. Such as a hypothetical event in which Nyaan found herself cheering Machu on as she ran in some kind of footrace. This Machu had a toned, lean figure, whipcord muscle spreading from her legs up to her exposed midriff. Nyaan screamed support from the sidelines, the real Nyaan mimicking her fantasy self's cries as whispers.
Other hypotheticals were lewder, going deeper and deeper into taboo as Nyaan descended into her own latent lust. Fingers digging deep into soft, bouncing flesh. A throbbing cockhead peeking out from overstretched underwear. Slick sweat filling the room with its bodily aroma, the air hanging heavy and wet. Nyaan moaned softly as she reached down to unzip her jeans, her eager cock begging for release at this point. With a gasp, she reached into her tenting underwear and pulled out her member, the cool afternoon air nearly stinging against the hot, sensitive skin. Nyaan knew her penis was... unconventional to say the least. Even ignoring its length, a jaw-dropping 12 inches, the first thing that jumps out is its shape. Nearly perfectly cylindrical, absolutely covered in veins and flared at the top into a nearly flat peak. It resembled the genitalia of a stallion more so than a human's.
Nyaan slowly wrapped her fingers around its length, inhaling sharply at the skin on skin contact. Eyes closed, falling deeper into fantasy, she formed a loose fist around her now throbbing cock, her hand barely reaching all the way around the girth of her veiny rod. She sighed in anticipation, slowly sliding her hand up, preparing to pump the soft flesh downwards...
"I'm home!"
In an instant, the front door swung open, Machu stepping out of the doorway with a bounce in her step. Fumbling frantically, Nyaan quickly grabbed a blanket that was hanging off the side of the couch and laid it haphazardly across her lap, holding her erect shaft down with her hands beneath the fabric. With gritted teeth, Nyaan forced herself back into casual mode, hoping Machu hadn't caught her in the act.
"Oh hey Machu. Where did you go?"
Machu held the container of protein powder up, grinning wildly. Nyaan breathed a sigh of relief, Machu had seemingly been none the wiser to Nyaan's lewd antics.
"Took your advice of course! Maybe a little too literally, but I thought finding some supplements of my own couldn't hurt. Picked up some protein powder from a wicked sketch shop on the other side of town. But I think this'll be just what the doctor ordered!"
Machu moved into the kitchen, finding a shelf to store the container on. While she was in the other room, Nyaan took the opportunity to return her softening meat to the confines of her pants. Machu returned, holding two glasses and a liter of soda.
"Wanna find something to watch?"
---
Over the next few weeks, Machu would find a steady regimen for her workout, motivated by the promise of that "special" powder. She started every day with a protein shake, Nyaan often making fun of her for acting like some kind of "dudebro". She ran on the treadmill daily for at least 30 minutes, but usually more than that. Eventually Nyaan came to her with complaints about the constant noise, so Machu made a habit of going out for runs too. Machu took it upon herself to do the grocery shopping now, Nyaan previously being the sole owner of the chore. Machu picked out richer foods than they had ever selected in the past, full chicken breasts and ground beef, alongside rich vegetables like leeks. Machu wasn't really much of a cook, but it was nothing a good tutorial video couldn't fix. For a the last two weeks, homemade chicken soup had become a staple in the household, which Nyaan couldn't really complain about. In fact, all in all, she could tell that Machu's new health crusade was actually doing everyone well.
As the two huddled together on the couch, sipping hearty broth from their near empty bowls, Nyaan softly smiled to herself. But beside her, she could feel a frustration building within Machu. While she had been doing a good job at putting on a happy face, Nyaan could tell that Machu was growing impatient. She had been promised change, and she was doing everything right. But so far, Machu still just looked like Machu. Nyaan understood that these things took time, but Machu was eager, overeager. Nyaan couldn't help but worry that Machu would do something drastic.
-Monday-
The next morning, Machu stood nude in front of the bathroom mirror, examining every inch of her form. Her legs felt a little firmer than they had been before, and maybe a little flab had been shaved off the stomach. But Machu had bought that powder with the dream of real change. Machu got that you couldn't get your dream bod overnight, but dammit she was working hard, and what did she have to show for it? Nicer calves? Machu threw on some loose clothes and stormed into the kitchen, making a beeline for the powder in the cabinet. Taking out the biggest glass she could find, Machu began pouring copious amounts of powder into the glass.
"Time for a stress test, yeah? Let's see how special you really are."
Stopping only when half the container had been drained, Machu filled the rest of the glass with water and stirred vigorously, the powder and water congealing into something approaching pudding. Holding her nose and tilting back her head, Machu began downing the concoction all at once, her throat bobbing with each greedy swallow. With a heavy exhale, she finished the entire glass in one go, holding the countertop to keep herself upright. Straightening herself out, Machu set the glass down and returned the powder to the cabinet, eyeing it suspiciously.
"Now let's see some goddamn results."
-Tuesday-
Nyaan stood sheepishly outside of Machu's room, her lightly shaking hands full carrying a stacked tray of food, alongside a single glass of water. Reheated leftovers piled high on the plates, Nyaan silently upset she was unable to prepare anything new for Machu. Freeing one hand, Nyaan knocked lightly on Machu's door, immediately opening the door just enough to allow herself access.
"I've got some food for you, if you're hungry..." Nyaan offered, her voice soft and quiet. Nyaan stepped closer to where Machu laid, lowering the tray to the bedside table.
Below her on the bed, Machu was a wreck. Her face was beat red, forehead hot with fever. Cold sweat sluiced down her body, pooling in the light sheets she was wrapped in. With a weak hand Machu reached up to the tray placed beside her, grabbing the cup of water and sipping on it lightly.
"Mhgnnn... thanks Nyaan..." Machu mumbled out, too weak to speak much louder than a whimper. This sickness had been ravaging Machu's body since the moment she woke up in a puddle of her own sweat this morning. The fever was terrible, blurring her vision and thoughts. But worse still was the soreness, her muscles feeling like they were working overtime. Her upper legs were screaming, her chest joining its choir. It frustrated Machu to no end, having spent these last few weeks treating her body with such care only for it to bite back like this. And the culprit was obvious; the protein powder. Machu should have known better than to take so much of a product she bought from a rusty old shack. She'd be kicking herself if her legs would listen.
With a quiet "You're welcome", Nyaan left the room and closed the door behind her, leaving Machu to her plight. It pained Nyaan to be unable to help her roommate more in such a trying time, but she wasn't sure what else she could do. She already gave Machu some of the little medicine they had in the house, she kept her fed and gave her water, after that Nyaan was stumped. Laying down on the couch, Nyaan thought back to the night Machu brought that powder home. That damn powder, if Nyaan hadn't been so busy being horny maybe she would have had the sense to make Machu throw the stuff away. But the damage was done, and now they both had to pay the consequences. Grabbing a blanket off the floor, Nyaan settled down for an afternoon catnap. Better to sleep than to stress, she always said. She hoped, at least, that tomorrow would be better for Machu.
-Wednesday-
Nyaan was up early Wednesday morning, preparing a light soup over the stove. She had wanted Machu to wake up to something fresh and hot, unlike the leftovers she was served the day prior. A light dusting of blush came over Nyaan's tanned face, the thought of Nyaan's soup helping Machu feel better was a comforting one. But suddenly, a shrill scream filled the house, Nyaan nearly dropping her ladle in shock.
"AAAAAAAAAAAAHHHHHH OHMYGOD OHMYGOD OHMYGOD!!!"
The source was obvious, Machu was up and something was wrong. Abandoning the stove, Nyaan raced for Machu's room, a million sour thoughts filling her mind. But as she opened the door in a panic, the sight before her made all of those thoughts go numb.
There Machu stood, bouncing excitedly in front of her mirror, wearing nothing but her underwear. She looked completely refreshed, her face bright and free of the fever that had plagued it just a day before. But Nyaan, to her own shame, wasn't looking at Machu's face. Machu wasn't just better, she was... more.
On Machu's chest, where once two modest perky breasts sat, two absolute melons bounced in their stead, each one slightly larger than Machu's own head. They were full and perfectly plump, almost impossibly so. Nyaan almost wanted to say they were implants, even though that was impossible unless Machu had snuck out last night to get an impromptu boob-job. Lower on Machu's new body, right below her toned waistline, her hips absolutely exploded outward. Her thighs had become absurdly thick, her hips now wider than her own shoulders. And in the back, good god her ass! What was once a completely flat and unremarkable rear had become an absurd dumptruck, perfectly rounded and filled to the brim.
Machu giggled to herself as she bounced, simply elated at this unexpected development. Her entire body bounced with her, her balloon-esque breasts repeatedly bumping into her chin before falling back down. Her ass wobbled wildly, her perfectly-sculpted asscheeks clapping rhythmically with the movement of her body. Nyaan blankly rubbed her widened eyes, uncertain if she was even looking at reality. It just seemed so... impossible! One day Machu's as sick as a dog, the next day, she's up and 40 pounds fuller!? Finally, Machu looked over her way, a huge grin plastered on her sunny face.
"Ohmygod Nyaan! Are you seeing this?! It seems like that powder really was the real..." Machu trailed off suddenly, her cheeks flushing as red as her hair. Dropping her gaze, Machu brushed past Nyaan and out of the room, accidentally knocking Nyaan aside with her newfound knockers.
"I'm gonna... grab myself some breakfast," Machu muttered, shuffling quickly down the hall. Nyaan simply stood there, wide-eyed and confused at Machu's sudden change in composure. Her gaze dropping to the floor, Nyaan gasped as she saw the cause of Machu's rapid exit. Nyaan's cock, now at its furious full length, had escaped the confines of her underwear, and trailed down her quivering leg. Sticking out of the bottom of her shorts in the cold morning air was her flared cockhead, dribbling pre down her thigh. Her face going a ghostly white, Nyaan made a beeline for the bathroom, cleaning herself up and returning her throbbing member to its cloth prison, no matter how much it begged for release. Just as Nyaan was catching her breath, Machu's voice once again rang through the house.
"Uh... is something burning?"
"Oh shit, the soup!"
---
Nyaan sat cross-legged on the couch, waiting patiently for Machu to reappear. She tapped a steady rhythm on her denim-clad knee with her index finger, seeking desperately for some sensation to drown out the impure thoughts that had been flooding her mind the whole day. Machu's voice rang into the living room from the hallway, Nyaan perking up at the sound.
"I think... I think I found something that works!"
Machu waddled into the living room, her face somewhere between a manic grin and a pained grimace. A once loose, oversized red t-shirt clung desperately to Machu's expansive breasts, stretched too thin to cover her midriff. Her overextended bra was clearly visible underneath, both it and the shirt failing to completely hide Machu's newly puffy nipples. Across her waist stretched a pair of gym shorts, its seams close to bursting as it attempted to contain Machu's double-wide wagon. A large chub was clearly visible at her crotch, the material of the shorts cupping her contained cock tightly. Machu fidgeted with the outrageous outfit frantically, trying in vain to look a little more modest. But with a body like hers, that was a pipe dream.
"This isn't too bad, right? I could maybe... probably go out like this, no?"
Nyaan squinted in response, torn between wanting to encourage her newly busty friend, versus sparing her as much embarrassment as possible. Nyaan's gaze darted to the side, deciding the less time she spent ogling Machu's brand new bod, the better.
"Umm... it would probably be fine... Earthnoids are used to seeing weirdos out in public anyway I guess."
"Exactly!" Machu perked up, apparently quite excited about being a weirdo. "Why don't we put that theory to the test and do a little clothes shopping?"
Nyaan's eyes went wide at the suggestion, the prospect of walking side-by-side in public with this new and improved Machu was... both alluring and terrifying to her. Nyaan took a breath, trying desperately to still her firing nerves.
"It'll be fine, no problem!" Nyaan reasoned to herself, trying to talk herself into doing something that was possibly very stupid. "Everything will be okay if I can just... keep it in my pants!"
"Alright, let's do it!" Nyaan declared, an uncharacteristic amount of boisterousness filling in the gaps of her insecurity. Machu clapped and cheered, her explosive rack jostling at the rapid movements.
"Then what are we waiting for? Let's go!"
---
Nyaan was going to die right here in the dress aisle. She was sure of it. She had been fighting for her life ever since she and Machu had stepped into this shopping center. She knew she would have to reign herself in while she was with Machu now, but she wasn't prepared for just how lewd Machu's body really was. Every step she took was an event, her entire body responding to the motion. Her tits bounced up and down to the rhythm of her footfalls, her shirt barely succeeding in keeping her uber-sized funbags contained.
Even more unbelievable was Machu's absolute wobble factory ass! It didn't just bounce with every step Machu took, it audibly clapped, the overstretched gym shorts unable to stop her two mountainous globes from constantly colliding. As Machu and Nyaan strolled through aisle after aisle, Nyaan's senses were overwhelmed by the audiovisual miracle in front of her. It didn't help that Machu was a fast, overeager walker, forcing Nyaan behind her at almost all times. And god, Nyaan had to move mountains to prevent herself from spending the entire trip just staring at Machu's extra-thicc cake. The two were walking down yet another aisle, layered with dresses and shirts ten times too expensive for the duo to even consider buying. Nyaan's brain was mush by this point, completely distracted by both thoughts about the woman walking in front of her, and the throbbing pain of her erect cock trying desperately to escape her jeans.
"Ooooh, this one looks niEEEP-!" Machu had suddenly halted her forward progression, stopping to check out an XXL dress that had caught her eye. Nyaan, unable to register this fact in time, walked directly into Machu's back, both of their eyes blowing wide at the sudden contact. In the collision, Nyaan's twitching bulge had jammed itself between Machu's prone cheeks, the sudden scraping of clothes against clothes sending shockwaves through the bodies of both girls.
And just as quickly as they had joined together, they separated, Nyaan throwing herself onto the cold ground below in her frantic attempt to escape the clutches of Machu's rear. The pair locked eyes only for a moment, both wide with shock and need. Nyaan, terrified of the confrontation, and desperate for some alone time, fled the scene, making a beeline for the changing rooms. She barely even heard Machu calling after her.
Nyaan shut the door behind her and sat heavily on the mounted bench, breathing heavily as she pawed desperately at the button to her jeans. Loosening the latch, her cock finally freed itself from its denim prison, its full 12-inch glory glistening in the cold, controlled air. Without hesitation, Nyaan grabbed at the hardening flesh of her throbbing member and pumped downwards, desperately fucking her own fist. She needed this right now, needed release more than anything else. Her nerves were still on fire from her accidental contact with Machu, the feeling of her furious bulge jamming itself into Machu's expansive back-crevice was left imprinted into her brain. Nyaan had to bite her lip to avoid moaning out Machu's name right then and there as she relentlessly pumped her hips into her own hand. The world around Nyaan was blurring, reduced only to the sensations of her needy, vein-striped cock.
"Nyaan?"
Nyaan's ears were ringing, but she could hardly care. All that mattered was emptying her balls once and for all. She brought her left hand down to join her right, gripping her thick rod with both as she pumped rapidly into them. Thin precum was filling her palms, dripping down her thighs and splattering onto the linoleum floor below, but Nyaan barely even noticed, much less cared.
"Nyaan are you in there?"
She was so close, so close to getting out all of these pent-up feelings. Maybe she'd be able to look Machu in the eye, now that she had came from just the memory of her absurdly thicc body. Images of bouncing, swollen breasts and wobbling, bubbly asscheeks swarmed Nyaan's mind. Nyaan shut her eyes tight, just one more pump into her quivering fists, and she'd finally be in heaven!
"Nyaan, I'm coming in!"
The changing room door swung open wide, Machu's overstuffed body moving forward to fill the empty doorframe. Machu didn't even have time to gasp in shock before a rope of virile sperm splashed across her face. Several more stands of seed jettisoned across the room, Nyaan's cock spurting wildly into the air. Most shots landed directly on Machu's heaving tits, seeping into the thin material of her shirt. Lower shots splatted against her exposed midriff, the liquid pooling in Machu's naval. The highest shots stuck themselves in Machu's bright red hair, the thick white color of Nyaan's sperm standing out garishly. With one final spurt Nyaan finally emptied herself out, a content sigh leaving her mouth. Satisfied and relieved, she opened her eyes, only to see a wide-eyed, cumstained Machu looking down on her.
Recoiling where she sat, Nyaan covered her hand with her mouth, mortified by the sight in front of her. Oh god, Machu probably hated her now. She was definitely disgusted by her, and unbelievably offended. Nyaan was panicking, the pleasant fantasies that once filled her thoughts quickly replaced with visions of being kicked out of their house.
"I-I... I'm... I..." Nyaan sputtered, completely clueless as to what she could possibly say. Machu's gaze was intense, and unbreaking. One eye still closed from a cumshot that had landed there. Machu moved for the first time since appearing, grabbing at her waistband. Nyaan's gaze followed the motion, traveling down Machu's seed-speckled body to land on her crotch. Machu's gym shorts were absolutely tented. A furious erection was fighting to break free from within, throbbing incessantly against the tight cloth that held it back. With a single movement of her thumb, the shorts waistband slid down, Machu's cock springing free into the tense air with immense force. Nyaan flinched at the sudden motion, her eyes locked with Machu's one-eyed appendage. It was so goddamn big, at least twice as big as it was prior to Machu's transformation. Nyaan had always prided herself on her lengthy shaft, but she knew then and there that Machu had her beat by at least 3 inches.
Without saying a word, Machu gripped her throbbing erection with one hand, the shaft too thick and veiny to fully wrap around. Then she started pumping, pumping fast. Her entire body rocked at the violent motion, her balloon boobs bounced and shook frantically, the nipples visibly pulsing against the tight shirt covering them. Nyaan could hear the soft clapping of Machu's restless ass behind her, matching the rhythm of her cock-pumping. Nyaan stared transfixed at the sight of Machu pounding her meat, unable to tear her eyes away. She couldn't see it, but Machu's face was becoming a mess. Her cheeks flushed bright red, her face growing hot and humid. Tears pricked at her eyes, the sensation of her overeager jerkoff growing too intense.
Within seconds, Machu had reached climax. With a hearty groan she just couldn't hold in, Machu crumpled forward at the release, her body giving way at the sheer eruption of sensation. Thick sperm sprayed relentlessly from her stretching cocktip, launching across the room and drenching Nyaan where she sat. Nyaan coiled backwards on instinct, the torrent of hot seed showering her from above. After five intense seconds of non-stop ejaculation, Machu's fierce rod finally settled down, the last spurts of milk falling short of their target and onto the ground below. Both girls were absolute wrecks, breathing heavily as their spent cocks stood stalwart in the now humid air of the changing room. Coated generously in each other's baby-batter, they remained in tense silence, their labored breaths the only source of noise. The small, enclosed space of the changing room had been overwhelmed by their expulsions, the atmosphere heavy and wet, the stench of fresh semen flooding their nostrils. Finally, Machu broke the silence, a light giggle spilling gracelessly from her mouth. That giggle grew and grew, until she was outwardly cackling at the absurdity of what had just occurred. Nyaan cautiously joined in, a symphony of carefree laughter filling the changing room. Machu wiped her face as her laughter died down, finally cleaning off one of Nyaan's spent shots.
"Phew! There, now we're even! Let's clean up and go home already, I'm starving!"
-Thursday-
Nyaan woke up groggy and lightheaded, stretching lazily as she sat up in her bed. She had barely slept at all the prior night, too preoccupied rerunning the previous day over and over in her head. Machu's sudden... enhancements, their clothes shopping trip, and good god, the changing room. Even though both girls had taken long, hot showers as soon as they had returned home, Nyaan felt as though she could still feel and smell Machu's cream staining her body. And if she licked her arm... she could still taste it too. Nyaan shook her head, trying to get such lustful thoughts off of her mind. She just woke up and she was already stiff, it was pathetic. Doing her best to tuck her erection into her pants, Nyaan went about her everyday morning routine, trying to maintain some level of normality. Washing her face, brushing her teeth, the usual. Grabbing herself a glass of water from the kitchen, Nyaan walked into the living room...
...and dropped the cup on the floor.
There, laying face-down on the couch, was Machu. Machu was resting her head on her own spilled-out tits, her plump nipples peaking out from the too-short shirt she failed to cover them with. The bra she was wearing yesterday was nowhere to be found. But much more evident than her bare tits was her absolutely planetary gooncake ass. It stuck out in the air prone, no pants in sight. Instead, a thin, white pair of underwear stretched across the massive expanse of her hips and ass, looking more like a micro-thong with how it was stretched to its limits. Machu looked over her shoulder at the helpless Nyaan, the sound of her cup clattering to the floor alerting Machu of her entrance. Machu grinned, a smug look settling on her face.
"Well? Are you just gonna stand there?"
Nyaan felt like she was paralyzed, she couldn't move a muscle even if she tried. Laying down before her was everything Nyaan had ever wanted and more, every fantasy made manifest right there in their living room. But after this, there would be absolutely no going back to how things were. Yesterday could have been a fluke, but this would seal the deal. And so, Nyaan had a choice. Reach out and grab a fistful of wobbling destiny, or retreat to the comfortable status quo?
"...Fuck it."
Nyaan marched up to the couch, ignoring the pain of her searing erection as she walked. She heard Machu squeal in what she hoped was excitement, a satisfied smile filling Nyaan's face. Nyaan hopped up on the couch behind Machu, on her knees straddling both sides of Machu's legs. Immediately, the confidence started to drain from her. From up this close, Machu's butt was... insurmountable. Machu's absolute bounce-house completely filled Nyaan's vision, the skin so shiny and tight she could almost see her own reflection.
"Cmonnn whats the holdup? Scared of a little booty?" Machu teased, clearly having way too much fun toying with Nyaan. Nyaan gulped, sweat beading on her forehead. With shaky hands, Nyaan reached down to the dumptruck below her, pressing her fingers into Machu's bubblegum flesh. Nyaan's digits sank in deep almost immediately, being swallowed whole by Machu's elastic ass. Machu bit her lip, the sensation of Nyaan's warm hands diving into her cheeks a completely new feeling for her. She subtly wiggled her hips, silently encouraging Nyaan to go further.
Nyaan, a bit uncertain of how to continue, decided to just go with her instinct. She moved her hands rhythmically against Machu's malleable cake, kneading the soft dough of her butt with long, slow strokes. Machu's toes curled at the feeling, from her perspective, Nyaan was a total natural.
Nyaan slightly raised her pace, increasing the scope of her ministrations. But as Nyaan spread Machu's globes out, she caught a glimpse of something hidden away inside her deep crevice. Machu's tight asshole, glistening and winking shamelessly. Nyaan suddenly pulled back, the sight too much for her to handle. Machu raised an eyebrow at the sudden loss of contact, looking over her shoulder at Nyaan behind her.
"Hmm? What's the holdup? You were doing really well!"
"I um... I saw..." Nyaan sputtered, the sharp aching of her erection trying desperately to escape her pants dulling her thoughts. Machu just rolled her eyes, finding Nyaan's hesitance adorable.
"You saw my needy pucker? In that case don't be shy, it's needy for a reason." Machu giggled to herself, playing the seductress was more fun than she had thought it would be. Deftly moving a leg up, she hooked the hem of her tight underwear with her toe, pulling it down and off in one smooth motion Nyaan simply stared back wide eyed, before finding a second wind of determination. Reaching for her zipper, she released her pulsing cock from its prison, already at its full footlong mast. Its flared, flat tip thumping hot with need. Machu could feel the heat emanating off of it already, just the knowledge that Nyaan had her dick out was making Machu's own shaft harden underneath her.
With her face beat-red, Nyaan gripped her meatpole at the base with both hands, needing maximum control. She moved to lower herself down, her veiny rod rapidly approaching its salty target. At the last second, Nyaan got cold feet, her descension slowing as she reconsidered. Nyaan knew Machu was craving this, craving her, but Nyaan needed a little more time to mentally prepare for... that. But still, she couldn't disappoint Machu, so Nyaan went for an alternative. Lining her shaft up perfectly with Machu's prone cheeks, Nyaan brought her stallion rod down to slide in-between them, hotdogging Machu's perfect ass. And just the contact of her dick against Machu's smooth wagon was enough to nearly set Nyaan off. Precum spilled haphazardly from Nyaan's tip, traveling down the footlong mass and pooling between Machu's cheeks. Machu gasped as the hot, thin seed hit her skin, a needy lump rising in her throat.
After a long pause, Nyaan got to work. Pushing her hips forward, Nyaan sent her glistening cock sliding up Machu's clapcakes, spreading her pathetic spend across its length. Forward and back Nyaan rocked, wedging her slick member deeper and deeper between Machu's quivering globes. Nyaan grit her teeth, the feeling of Machu's mountainous dumptruck slowly swallowing her shaft was just too much! Machu was ready to start begging, she needed that 12 inch fuckstick inside her tight hole NOW! Luckily for her, Nyaan was also becoming impatient, her once steady motions growing rapid and thoughtless. Nyaan panted, her breath heavy and wet.
"Can I... c-can I..."
"YES!!! YES PLEASE FUCK MY BACKDOOR WITH YOUR EQUINE COCK!!!"
Machu didn't even let Nyaan finish, having grown too desperate to keep up the seductress act. With sweat running down her neck and her heart beating out of her chest, Nyaan repositioned her pulsating meat. Pushing it down directly into Machu's deepest parts, its tip pressed snuggly against Machu's puckered whole. Closing her eyes, Nyaan took a breath, before pressing her cock forward cautiously. In an instant, Nyaan's flared cockhead pierces Machu's needy slot, both girls crying out at the sensation.
"FUUUUUUUCK! NYAAN! YOUR C-COCK IS SO HUGE IN ME!!!"
Nyaan panted heavily, moans and grunts escaping her lips. She looked down at where their bodies met, finding that she had only sunken about 2 inches of her full length into Machu's entrance. Gritting her teeth, Nyaan slightly repositioned herself, preparing to dive as deep as possible. With another sudden thrust, 3 more inches sank inside, more cries of impossible pleasure coming from the two girls. The air in the living room was heavy and humid now, sticking to the girls' sweat-soaked skin. As Nyaan pushed even deeper, Machu raised her ass to allow even easier access to her widening trap. Machu now kneeled up on her knees, pushing her face and chest into the soft couch cushion below. Machu's furiously throbbing cock, previously trapped underneath her, was finally free to dangle heavily below, pushing eagerly into the surface of the couch.
With her newfound leverage, Nyaan was getting into the zone. Grabbing both sides of Machu's wide-blown childbearing hips, Nyaan pushed forward yet again, Machu drooling into the pillows below. Nyaan was grunting and sputtering, her brain short-circuiting from the intense pressure and heat of Machu's insides. With one final desperate push of her hips, Nyaan bottomed out inside Machu, Machu's titanic ass colliding heavily with Nyaan's stomach. Nyaan mewled and gasped for air, saliva trickling down her chin and splashing against Machu's creamy cheeks below. Machu meanwhile, was panting like a bitch in heat, pushing her face harshly against the cushions below.
"F-F-FUCKKKKK!!! Y-YOU'RE SO FUCKING BIG!!! POUND ME, BREED MY ASSHOLE UNTIL I CAN'T EVEN WALK!!!" Machu begged, Nyaan's static-filled brain barely able to recognize the words coming out of Machu's mouth. With a hefty groan, Nyaan began sliding her fuckrod out of Machu's sloppy hole, her shaft drenched in both hers and Machu's juices.
And just as quickly as she pulled it out, Nyaan jammed her battering ram dick right back inside of Machu. As Machu's ass slapped loudly against Nyaan's quivering core, both girls cried out yet again, the capacity for proper speech no longer within them. All that existed now was the two of them, and the intense, impossible need for sweet release.
*PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!*
"FUUUUUUUUUUCK!!!"
Machu's voice was muffled by the cushions, soaking up both her words and the drool splattering out of her loose mouth. Nyaan was grunting like an animal with each frantic thrust in and out, her floppy tongue hanging loosely out of her slacked jaw. Her eyes crossed at the pleasure, tears pricking at the corners. She couldn't think straight, she could barely think at all. But it didn't matter. All that mattered now was cumming inside the slutty piece of ass beneath her.
*PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!*
A steady buildup of liquid had begun in Machu's ass crevice, a mixture of precum, anal juices, sweat, and spit. That mixture splashed wildly every time Nyaan's hips collided with Machu's furiously bouncing bubblebutt, the concoction spilling out onto both girls and the room around them. Eventually, the muscles in Nyaan's core gave out under her, no longer capable of keeping her kneeling up. She fell forward, lying across Machu's sweat-beaded back. That didn't stop her manic thrusting of course, because nothing could.
Eventually, between intense thrusts, Machu's own cock gave out, twitching wildly beneath her before spilling waves upon waves of thick seed across the couch below, the pool quickly spilling over the edge and onto the floor. Machu's eyes rolled back, the dual sensation of her own release and Nyaan's ravaging of her asshole too much for the girl to handle.
*PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!* *PLAP!!!*
Nyaan was close, so close, she could feel it. She wanted to tell Machu, she needed to, but her damn mouth didn't even work anymore. Her entire body had given up its functions to let her fuck Machu's hole as furiously as possible, like its what she was made to do. With one last thrust, and a primal cry of relief, Nyaan pushed deeper than ever before into Machu's insides and began releasing her torrent of sperm. Her balls churned wildly and Nyaan sputtered and drooled. An unending wave of viscous cum filled Machu's pipes, quickly pushing even further in and flooding her stomach. The pressure of her insane release was growing too tense, forcing Nyaan to slide her still-spraying cock out from Machu's backdoor.
As soon as Nyaan's throbbing cockhead popped out into the open air, it began coating Machu's pale fleshglobes with wave upon wave of white batter. Machu barely reacted, intense heavy breathing her only remaining sign of life. Nyaan watched in awe as her hot runtslime drowned Machu's enormous booty, some especially powerful shots splattering against Machu's back, staining her already soaked shirt even further. The two remained in this way for ten seconds longer, before Nyaan's overeager bitchbreaker finally ceased its spurting. By now, Machu, and the entire couch beneath her, were absolutely drenched in steaming, thick girlcum. A satisfied sigh came from Machu, some semblance of her wits finally beginning to return to her. Nyaan's head was still spinning, she could barely believe what had just occurred. But more than anything, one momentous question dominated her mind.
"Machu?"
"Mmm."
"Did... was it good?"
"...Are you kiddin'?"
"..."
"..."
"Lets do this every mornin', okay Nyaan?"
THE END
