It was a normal, quiet Saturday morning in Team RWBY's dorm room. To Weiss' surprise, she was up before even Blake, the team's earlybird, meaning she was the only one up right now. Quietly, she set her feet down on the floor and padded to the bathroom to freshen up.
Once she had washed her face and brushed her teeth, she took a moment to admire what she saw in the mirror. Her hand drifted down to her belly, and the small pouch of fat she had grown there. It hung low on her marginally widened hips, jiggling with every move Weiss made and being soft enough to easily take Weiss' fingers as they sunk into her belly fat. It was big enough to begin to press against her combat outfit, and it made Weiss' nightgown, which she was wearing at that moment, pull tight enough across her belly that it showed an outline of her navel. It was even getting to the point where Weiss was on the verge of needing to upsize her Beacon Academy uniform, as opposed to before when it was just a good idea. It was not much of a gain, maybe a 10kg gain at most, and it did not make much of an appearance on the rest of her body beyond just a very slight bit of fat, but Weiss was proud of it.
The cause of the gains was, primarily, due to her bonding binges that she undertook with her team leader and partner, Ruby. Sure, the two of them would indulge in snacks from time to time, but what they did every Saturday was beyond mere indulgence. These binges were the two of them throwing out every last ounce of restraint they had and giving into pure, unbridled gluttony. When the pair got to wherever they were eating, they would eat and eat and eat. They would not stop eating until their bellies were large, full and heavy, they would not stop eating until it hurt too much for them to keep eating. Weiss could not speak for Ruby, but Weiss absolutely loved it. In fact, 'loved' might have been putting it lightly, she was borderline addicted to it, the feeling of an achingly full belly, the feeling of letting go of all restraint, being able to stuff herself with all sorts of delicious food, all of it. Her Saturdays were mostly spent waiting for it to happen, and after the two of them stuffed themselves to their absolute limits, Weiss always needed to duck into the bathroom to quickly masturbate, just to clear her mind for long enough for the two of them to get back to Beacon Academy.
Sinking her fingers into her belly brought Weiss back to a common daydream of hers. In it, well in the future, she had the opportunity to fully give in to gluttony, and to never again need to hold back. She would grow to an immense size, wide enough for normal doors to be too narrow for her, with a big enough belly to block her view of not just her feet but of almost everything beneath her. She would be so heavy that every waddling foot step was slow and laborious, making her entire body wobble and jiggle like jelly, not that she would be walking much at that size. Ideally she would be spending as much time as possible sitting or laying down, eating as much as she could whenever she could, just growing fatter and fatter by the day.
Such a dream was incredibly titillating for Weiss, enough so that her core began to immediately heat up. She slipped her hands under her nightgown, one gliding up to rub and grope her little belly while the other slipped into her panties so she could finger herself. Weiss' time at Beacon had sent her sex drive through the roof, and, due to sharing a dorm, Weiss got very good at masturbating quietly. All anyone would have heard was Weiss' fingers working her slick core and her panting for air, and that was only because Weiss felt safe behind this bathroom door.
One orgasm and a pair of washed hands later, Weiss was ready to face the day. Surprisingly, no one else was. Being Saturday, Weiss was in the mood to get absolutely stuffed, but she did not want to do it without Ruby there. So, carefully, slowly, Weiss crept over towards the bunks. With a flick of her hands she set up a series of small glowing glyph platforms, giving her steps up to Ruby's bed. Once up there, Weiss took a moment to look at Ruby. Weiss had never woken Ruby up before, so there were some things Weiss had not noticed until now. When Ruby slept, she seemed to have a small smile on her lips, and she seemed to rub her modest potbelly as she slept. She also seemed to be one to sleep on her side, facing away from the rest of the team.
Weiss reached for the sheets covering Ruby and lifted them off of her ever so delicately, as if they would shatter if she was too rough with them. She was about to lean in to quietly wake up Ruby when Ruby rolled over on to her back, still asleep. Weiss then saw something she, frankly, never expected to see. There was a rather large tent pitched in Ruby's pyjama pants. Weiss may have had a somewhat sheltered upbringing, but even she knew what it was, even if it was far bigger than she thought they could be. She had no clue Ruby had one of these, but this was probably not a good way to find out.
Once Weiss's brain had finished processing what she was seeing, it then, very quickly, processed that she was accidentally perving on Ruby. Weiss let out a yelp as she threw up the sheets and stumbled backwards. Unfortunately, her glyph platforms did not give her much room to step back, so all her foot found was air. If accidentally perving on Ruby got a yelp out of Weiss, falling a good meter to land on her decently padded rear got just shy of a full on scream. That managed to wake up everyone very suddenly, with everyone bolting upright. The previously sleeping members of the team tried to piece everything together to figure out what in the world just happened. Yang was the first to figure it out when she saw Ruby quickly covering her crotch with her pillow. Yang let out a long sigh as she sat up and brushed her messy hair out of her face.
"Weiss, did you see what I think you saw?" Yang drawled.
"Y-yes," Weiss quickly answered in a small voice. Yang let out another sigh.
"Alright, give me, like, 10 minutes to wake up, me and Ruby can talk to you two about it," Yang said, groaning as her body complained about being up so early involuntarily.
Not long later, everyone was sitting down on the lower bunks, Ruby and Yang on one bed and Blake and Weiss on the other.
"So, Ruby, want me to do the talking, or do you wanna do it?" Yang offered.
"Um… can you do it for me?" Ruby asked in a small voice, her eyes locked on the ground.
"Don't worry Ruby, I got this," Yang said in a soft, reassuring voice as she gently patted Ruby on the back. "So, uh, yeah, you weren't seeing things, Ruby's… built a little different from the rest of us." Ruby's eyes went wide.
"I-I am?" Ruby asked, clearly confused and concerned.
"Ah crap, that might not have been the best euphemism, but yeah, you are. Me and Dad didn't wanna say anything, but that was probably a bad call and this is why," Yang explained, gesturing to the rest of the team. "I'll be honest, I was hoping we wouldn't have to have had this conversation any time soon."
"You told me it was normal," Ruby murmured, her face looking sadder and more pitiful than a puppy caught in the rain. Yang let out a sigh.
"I'm sorry Ruby," Yang said, putting an arm around Ruby. Weiss could not help but feel intensely awkward, knowing this was all her fault. "So, yeah, Ruby has a penis, she was born with it, and… shoot, I dunno… what else do you guys need to know? Excluding anything Ruby doesn't want me saying, obviously."
Not long later, with the remaining misunderstanding cleared up thanks to the follow-up questions Blake and Weiss had, things mostly seemed to go back to normal, or at least as normal as things could be for the team after all of that information.
"Well, that was… a lot," Blake commented.
"Yeah, I'm glad you guys were so chill about it, at least, after the first freakout" Yang replied. Weiss' face burned red, not wanting to be reminded of that.
"Y-yeah, me too," Ruby quietly slipped in.
"So… breakfast?" Yang suggested.
"Sounds good to me," Blake agreed, rising from the bed.
"I'll wait a bit. I want to speak with Ruby in private, if no one has any objections," Weiss requested. The other three agreed, and soon Yang and Blake were off to have breakfast.
Ruby made her way over to Blake's bed where Weiss was sitting and took a seat next to her.
"So, Weiss, what did you…" Before Ruby could finish, Weiss struck, leaping at her and pinning her to the bed, the pair's pudgy bodies pressed against each other. Ruby yelped in surprise, but that was quickly muffled by Weiss leaning in and locking lips with her. Ruby froze for a moment, before suddenly feeling very, very relaxed as she melted into the kiss, reaching and gently holding Weiss by the hips. She was almost disappointed when Weiss broke off the kiss. That was when Weiss reached between Ruby's legs for her bulge to begin rubbing it.
"I want this, Ruby. I want all of it," Weiss said in a low, husky voice that sent a shiver up Ruby's spine. All she could do was whimper and shuffle over so she was all the way on Blake's bed. Ruby could not make herself try to stop Weiss. Maybe she did not want to stop Weiss, she thought. Maybe she wanted this almost as much as Weiss did, as there was no way she was matching Weiss' extremely obvious horniness. Ruby squirmed in place as Weiss' hand kept working, making Ruby's member grow, and grow, and grow. Weiss was actually caught somewhat off guard by just how big it was getting, it was even bigger than what she saw when she woke Ruby up. She just had to see it with her own eyes to be sure. She tugged off Ruby's flannel pyjama pants and revealed the behemoth between Ruby's legs. It would have run all the way down to Ruby's knee if it had not instantly sprung up to stand at attention, and it was as thick as Ruby's arm. Weiss had never seen something like this before, not in real life and not in fiction. As she gawked at Ruby's monster cock, she noticed Ruby's belly begin to swell. Ruby already had a bit of a potbelly, thanks to the pair's bonding binges and Ruby's rampant sweet tooth, but this was much, much more. Her belly was growing large and round, almost spherical, and by the end of her swelling it looked like Ruby was five or six months pregnant. It pushed Ruby's pyjama top up and out of the way, making sure it was very, very visible. That growth surprised Weiss even more than Ruby's enormous dick.
"Um, Ruby, why did your stomach get bigger?" Weiss asked carefully.
"Oh, that. Uh, well, I'm not built like most people with penises, the bits that make the stuff that comes out when I masturbate are inside, and they swell up when I'm… y'know… in the mood. So, uh, can you promise not to… get me in the mood in public, please?" Ruby explained.
"Well, since you asked nicely, I suppose I can," Weiss acquiesced as she rubbed big, slow circles on Ruby's swollen belly. "I really like this though, so maybe I'll do this again sometime. Just when we're in private though," she cooed, nuzzling up against Ruby's belly. "Speaking of private…" Weiss began. She moved up towards Ruby's mammoth member. She opened her mouth and let Ruby's cock rest on her stuck-out tongue. Then, slowly, she took Ruby's cock into her warm, wet mouth. It was just the tip at first, but even just that was enough for Ruby to let out a quiet moan.
"Weiss… ah… s-so good," Ruby struggled to get out. If Ruby was this much of a mess now, Weiss thought, she was going to love what Weiss was going to do next. Slowly, steadily, Weiss took in more and more of Ruby's shaft, until she had taken Ruby's whole length. Ruby had no idea how Weiss managed it, and she did not care. She was too busy being on cloud nine, reaching new heights of pleasure she did not know were possible. And that was before Weiss even began to suck her off. Once she did, Ruby was instinctively grabbing the sheets and letting moans spill forth uncontrollably. Ruby's back arched and her heart raced as the pleasure was racing throughout her body. Ruby was panting, letting out the occasional moan of pleasure as Weiss kept sucking her off. Then, suddenly…
"Ah! W-Weiss! I'm…! I'm…!" Ruby could not quite get it out, but Weiss was about to find out exactly what Ruby was trying to say. Ruby's cock was throbbing in her mouth, Ruby's belly swelled just a little bit more, filling with just a bit more cum, all signs that Ruby had hit her point of no return. In one sudden moment, Ruby cried out Weiss' name in a passionate outburst as the dam broke. Ruby's cock began pumping an absolute torrent of cum into Weiss' mouth. Weiss was caught off guard, but despite that she managed to drink it all up. As it flowed out of Ruby, Ruby's belly began to deflate, slowly and steadily going down to Ruby's natural pudgy potbelly. As it poured into Weiss' stomach, it began to balloon up quickly. Weiss' belly grew from modestly pudgy to large, heavy, round, much like when the pair binged. The feeling was getting Weiss all hot and bothered as her mind and vision went hazy. She felt her belly tear through her nightgown, ruining a seam to escape the confines of Weiss' clothes. After escaping, Weiss' belly hung down enough to rest on the bed, making it clear how much Weiss' belly had swollen, as Weiss was on her hands and knees and there was a good amount of distance for her belly to cover, which it did with ease.
"Oh, Weiss! That felt so good!" Ruby cried out. Weiss removed Ruby's cock from her mouth, looking up at Ruby's face. When she did, looking through her hazy eyes, Weiss could have sworn Ruby looked bigger. Although, right now, Weiss did not fully trust her own vision. She had hoped to keep looking, to let her vision focus, but she was interrupted by a banging on the door.
"Ruby?! Weiss?! What the heck is going on in there?!" Yang yelled, her voice muffled by the door. Ruby yelped and dashed off to the bathroom, leaving Weiss there all alone as Yang barged in with enough noise to suggest that she probably did not use the scroll lock to unlock the door. Weiss whirled around to face Yang, with her belly overswinging, before correcting with a loud, heavy slosh and steadying.
"Oh, hey Yang," Weiss slurred, her blurry vision only barely registering who it was.
"Weiss, what the heck were you thinking, going after Ruby like that!?" Yang asked, almost accusingly.
"Your sister needed to grow up," Weiss answered, probably not intending to be so cryptic. Whatever point she had was quickly undercut, as Weiss let out a long, low, rumbling belch that went on for about ten seconds straight. As soon as that was over, Weiss' eyes rolled up, back into her head, as she passed out. She flopped back down onto Blake's bed, bouncing slightly and making her belly slosh even more as it bounced even more. All Yang could do was let out a long, annoyed sigh.
"Godsdamnit Weiss," Yang quietly grumbled, before leaving the way she came in, completely unaware of what had truly happened to Ruby.
Meanwhile, in the bathroom, Ruby was freaking out. In fact, saying she was freaking out might have been an understatement. Ruby was full on panicking in there. Every jittery, jumpy move she made made her newly expanded breasts, now each the size of coconuts, bounce and slosh. Even Ruby's new bountiful behind, which was even larger than her new breasts, just would not stop bouncing with every move Ruby made. To make matters worse, Ruby's expanded body no longer fit into her clothes properly. Her new breasts stretched her shirt so tight it was threatening to tear, and parts of it had gone see through. Her diamond-hard nipples were poking through the fabric, as if Ruby's massive breasts needed anything else to try and draw more attention to them. Meanwhile, Ruby was making an attempt to get her pyjama pants back on. Unfortunately, with her bountiful bouncing behind came equally large thighs and wide hips. No matter how hard Ruby heaved and tugged, Ruby's pants just were not going to make it up to cover her, or at least not intact. All of this was not even taking into account something that Ruby had barely noticed in all of the panic. Ruby had shot up about an extra six inches in height, now putting her around Yang's height. That had been enough for Ruby's top to ride up and expose some of her potbelly, and even if Ruby had been able to squeeze into her pyjama pants, they would have been far, far too short for her now.
All of this left Ruby feeling very conflicted. On the one hand, hoo boy, that had been the mother of all orgasms for inexperienced Ruby. Every orgasm Ruby had had until now had been her jerking herself off or humping a pillow or mattress until she came. None of that compared to the mind blowing pleasure of a blowjob. She had no idea whether Weiss knew what she was doing or not, but it still felt incredible. On the other hand, now she was in a hell of a predicament, being too big for her pyjamas and almost certainly everything else, and all of this was just because she woke up just a little too late and had Weiss reveal her secret. Honestly, Ruby was wondering whether it would have been better if all of this had never happened. At the very least, Ruby was going to be more careful from now on, and maybe remember to set an alarm even on the weekend.
