It was times like this when Yang was glad to have friends outside of Team RWBY. Yang had a dust studies project to finish and she just couldn't find her notebook, the notebook she could've sworn she'd taken with her to class that morning. Ruby and Blake were out shopping, and besides, they were a little too into their PDA for Yang's taste. Meanwhile, Weiss was working on the project on her own and while Yang wouldn't mind an expert like Weiss to help her out, she wasn't too keen on working with a perfectionist like Weiss. And so, with Team JNPR being the obvious choice, Yang marched on up and knocked. Nora was more than happy to let her in and help Yang out. She was already halfway through, but her notes were more than enough for Yang. Once Yang had the notes down, she was avidly watching Nora work, far more diligently and carefully than she expected, especially with all the protective gear on the table and the surrounding area.

"Ok, so here's the tricky bit," Nora warned, eyeing up the smoky deep purple concoction. "The moment this heat turns off, it's gonna start setting. Gotta be careful with it until it's all one big solid clump."

"Why's that?" Yang asked curiously.

"Apparently it's a little weird while it's still a bunch of particles, but it's not super consistent, so I don't know what's gonna happen. It all depends on how hot it is when I turn the bunsen burner off, how long I heated it, how long it's cooled for, all kinds of stuff," Nora explained cheerily, beaming a little with pride.

"That's pretty cool. I didn't know you were so good with dust," Yang praised. Nora's smile grew dramatically.

"Aw, thanks Yang. This is kinda my specialty, especially since I have to make my own grenades," Nora mentioned. "Oh hey, it's almost done," she interrupted herself, pointing to the dust and moving in close for a better look

"Huh, it is. That's pretty quick," Yang commented, moving in closer, spotting the smaller lumps the dust was beginning to form as it faded into a lavender colour, not too different from the colour of Yang's eyes.

"Yeah, it only take a... ah..." Yang had just enough time to realise what was about to happen, but not enough to react before...

"ACHOO!"

A puff of smoke exploded out of the beaker, enveloping the girls in a lilac cloud of smoke. The two of them were coughing up dust and doing their best to wave it away as they pulled back for some fresh air. After a minute or so, the two had recovered enough to start breathing normally and thinking straight.

"Nora are you... you okay?" Yang asked, trying to shake the dust out of her hair.

"Me? Are you okay? You must've gotten a faceful of that stuff," Nora replied, totally ignoring the purple tinge on her face and in her hair.

"And you definitely got one. You're all purple." Nora scoffed.

"I've had worse. Besides, if something bad was gonna happen, it'd happen by now unless we created some crazy new side effect. Now, let's get these notes done so we can clean up."

A few minutes of diligent work later and the pair had their notes all in order.

"Phew, that's that sorted," Yang said as she stretched. "I'm gonna go shower. Wanna work on the report together afterwards?"

"Heck yeah!" Nora cheered, getting a quick look at Yang. "Oh, hey, you're looking a little less purple now. I think I'm less purple too." Yang let out a sigh of relief. The pair were unaware that the dust hadn't disappeared or washed off, instead it had been slowly seeping into their skin to join the dust the pair had breathed in during the original burst of dust.

"Oh, thank goodness. Guess that stuff didn't do anything weird to us."

"It might still do something. If it does, we've got notes so we can say we did science and maybe get a reward or something once the effects go away."

With that, the two girls got up and went their separate ways, Nora to the bathroom and Yang back to her team's dorm. Yang felt a little light headed as she stood and moved, but she just assumed it was from getting up too quickly and shrugged it off. As expected, Weiss was at the desk writing away at her report. As the door closed behind Yang, Weiss turned to face her entering teammate.

"Oh, good, you're finally back. Maybe you should get started on the dust studies project." Yang pulled out her scroll and tossed it lazily in front of Weiss.

"I already got started. I've got notes and everything. You wanna read them before I start on the report, go nuts," Yang drawled as she sat heavily on the chair next to Weiss.

"Oh, excellent," Weiss said as she eagerly perused Yang's notes. As Weiss read, Yang held her heavy head in her hand.

'Maybe that dust is doing something,' Yang thought, both feeling like she needed a good stretch and to stay completely still. Her clothes began to feel uncomfortable all over, but Yang only felt like she had the energy to toss her shoes off. As soon as that was dealt with, Yang felt herself doze off, and she didn't really feel the need to fight it off.

Meanwhile, Weiss was reading away at Yang's notes, trying to figure out the right compliment for this impressive work without being excessive. Weiss thought she had done a decent job of being subtle. Her focus was broken as she heard a quiet plinking sound near her. She found a button sitting on top of her own notes. 'That wasn't there...' Her thoughts were interrupted by something bouncing off her cheek. "What the...?" she started, picking up another button. There was another interruption as Weiss heard the unmistakable sound of fabric tearing. Slowly, cautiously, Weiss turned. She reared back as she saw the cause.

Yang had already grown quite a bit in the short time Weiss had looked away. Her lengthening limbs made the chair look too small for her, while the growing torso kept everything in proportion, just taller. It wasn't just her height that had changed. Yang's already impressive breasts had grown dramatically, stretching her top and pushing against her jacket buttons. Her rear appeared to be plumper, filling out and overfilling her already tight shorts. On top of all of that, Yang's muscles were growing all over her body, bulking her up and straining her clothes. Weiss sat, transfixed by the display in front of her, frozen and tongue tied. Yang was already tall, strong, buxom and beautiful, but Weiss couldn't have imagined this except in her wildest dreams. But Yang wasn't done growing. Seams were giving out all throughout Yang's outfit, revealing more and more skin as her meaty body expanded. First her tank top gave out on her, the shredded remains falling around her. Her simple beige bra didn't last much longer, her flesh squeezing out everywhere there was an opening until the clasp and seams all gave out in a single explosive moment. Yang's jacket burst open at the front, revealing both her big bare breasts and her rippling, perfectly defined abdomen. Then went Yang's little black shorts. Her thick thighs split the seams around the hems of her shorts. Her hips popped the button on her waistband and pushed her fly down. Her sizable rear split the seams at the back and tore. Yang's plain white panties were stretched so tight they looked like they were painted on, and they were being swallowed by the gap between Yang's growing buttocks. Her panties and skin peeked through the little holes in her shorts. Then there seemed to be more holes than shorts. Then, finally, her shorts were finished, torn and useless, much like her panties just a moment later. Finally, there was Yang's jacket. Until now she'd gotten away with it just bursting open. Now, however, it had to contend with broadening shoulders and bulging biceps. The biceps were easy as the buttons on the cuffs popped and her previously puffy sleeves were filled in. The shoulders, however, were putting a lot of pressure on the jacket, pulling the back tight between them. Weiss snapped from her daze long enough to pull the jacket off, still mostly intact. Weiss couldn't help but feel just a little nervous doing this, but she figured that Yang's own body had done most of the work and she was just helping her out. If anything, she was kicking herself for not saving more of Yang's clothes. Soon, Yang was stripped bare, the destroyed remnants of her outfit tossed away.

Meanwhile, Yang was just finishing her growth spurt, filling out into a muscular mountain of an amazonian woman. She was much taller than before, and much, much curvier. It was an hourglass figure that had been majorly increased by plenty of muscle mass. With her growing over and done with, Yang's eyes fluttered for a moment before shooting open.

"Oh wow, that was a hell of a nap. I feel great now," Yang cheered, sitting up nice and straight and stretching her beefy arms out. She looked over at Weiss, about to ask for her notes back, when she saw her sitting there, slack jawed and staring at her. "Hey, Remnant to Snow Angel, you there?"

"S-Snow Angel?" Weiss stammered, her cheeks going pink and her eyes still fixed on Yang's superhuman body.

"Yeah, I figured you just ignore when people call you Ice Queen, and you always react when Jaune calls you Snow Angel..." Yang trailed off as she realised that she had lost Weiss' attention. "Seriously, is something on my shirt or...?" Yang looked down and saw a very different, and much more naked, body from what she saw when she fell asleep. "Uh, Weiss, is this real?" Yang asked slowly. Weiss nodded even slower. Yang carefully stood up, carefully balancing her new weight and rising to her new full height, putting her head above the top bunks in the room. She carefully paced around the dorm, slowly getting used to her new body. "Oh, man, I'm not gonna lie, being a total beefcake like this is pretty neat. I feel like I could tear an Ursa in half with my bare hands," Yang said, flexing her impressive biceps and feeling that they were built for unbeatable strength and definitely not just for show. Her hands ran down her massive mammaries and her curvy rear. "Can't complain about these either," Yang added, gently biting her lip before remembering that Weiss was right there. "Oh, uh, sorry. Getting a little carried away, aren't I?" Weiss nodded absentmindedly, her mind off with an annoyingly common thought.

'Why would she be interested in you?' her mind cruelly teased her. She never believed that thought at first, a little size difference like the half a foot between her and original Yang wasn't unusual. But now, Yang had to be the tallest, strongest, most beautiful person in Beacon Academy. Yang could have almost anyone in Beacon as her significant other, Weiss thought, so why would she pick someone so small and pathetic like her.

"Weiss, you okay there? You're looking really down," Yang asked softly.

"No! I love you, and you'll never feel that way about me!" Weiss blurted out. Weiss sat in mortified silence as she buried her face in her hands, just wanting the planet to swallow her whole and take her away from here, somewhere she didn't have to deal with her mouth going before her brain. Yang pulled up a chair and sat on down next to her, sitting carefully when she remembered how the chair was going to be much lower than it used to be. She put a big, gentle hand on Weiss' shuddering shoulder.

"Hey, why would you think like that?" Yang asked softly, rubbing Weiss' back.

"You'd never settle for someone like me, not when you could have whoever you want," Weiss answered in a brittle voice, still muffled by her hand. "Someone beautiful and attractive and amazing and kind and caring like you deserves someone better than me."

"Hey, c'mon, I'm not like that. I don't need to date some handsome stud or some hot babe to have a good time. I want to date some I like as a person. Someone... maybe like you." Weiss' hands dropped and she looked up at Yang's softly smiling face with watery eyes and a quivering lip.

"You... you really mean it?" Yang nodded.

"You're not the same person you were at the start of the year, Weiss. You're kinder, nicer, and honestly a better person. I probably wouldn't have dated the old you, but now, I could consider it. Your body won't change a thing, because I want a partner, someone I care about and someone who cares about me, not just eye candy." A surge of confidence flowed through Weiss as she rose to her feet.

"Speaking of nice, can I offer to get you a new wardrobe?" Weiss offered, back to her normal self.

"You don't need to do that," Yang dismissed, her arms drifting to cover her bare breasts and exposed core.

"But it will be so very expensive," Weiss interrupted. "You'll need uniforms, underwear, battle outfits..." Weiss paused for dramatic effect, "and maybe a new dress for dinner tomorrow night." It took a moment for Yang, but soon she was letting out a hearty chuckle that made her hefty bosom jiggle like jelly.

"Oh, wow, I don't think it's legal to say 'no' to something that smooth," Yang said with a big grin. "Guess you gotta measure me up for my new clothes," she added, standing and exposing her goddess-like nude form. Weiss' face flushed red.

"Yang, you need to warn me when you do that," Weiss said, trying and failing to admonish Yang.

"Hey, if you're gonna date all of this, you gotta be able to handle it," Yang said with a smug grin as she moved into Weiss' personal space. As Weiss got an eyeful of cavernous cleavage, she failed to notice Yang bringing her in for a hug. Weiss melted into the hug, comfortable and safe in Yang's mighty arms. With her face buried in Yang's cleavage, Weiss might have had less air than she would have liked, but everything else definitely overshadowed that minor, unimportant complaint. Yang craned her neck and bent down to softly kiss the top of Weiss' head. Weiss couldn't help but wrap her arms around Yang, barely reaching around Yang's beefy body and pulling herself in nice and close. "You liked that?" Yang asked, easing up on the hug. Weiss nodded quickly. "Well, maybe you'll like this." She lifted Weiss up so she could barely touch the ground. She brought her chin up with a delicate grip that Weiss couldn't help but follow. Then, she went in for the kiss. Their soft lips met, locking together like they were made for each other and the couple kissed like they needed it. And so, they kissed until they ran out of breath, breaking reluctantly for air as Yang held Weiss as if she were as light as a feather.

"I... wow," Weiss mumbled, waiting for her brain to turn back on. "I should get your new clothes sorted." Yang put on a devious grin.

"Or you could relax in bed with me and do it later," Yang suggested in a lilting voice. Yang's grip may have been feather light, barely a fraction of what her new body was capable of, but Weiss certainly didn't have the willpower to escape it.

"Yes, you're right. It can wait," Weiss said dreamily as the couple gently fell into bed, Yang basically being Weiss' beautiful, muscular mattress and her mammoth breasts the pillows. "This is nice," Weiss whispered, every little bit of tension disappearing immediately as she lay on Yang. Yang nodded and hummed in agreement. This was nice, and it could only get better. Maybe that dust accident wasn't so bad after all.
