It kind of… tingles, I suppose.
Blake hummed thoughtfully as she applied the dust to herself. This kind of dust was supposed to be absorbed through skin contact, so she had taken a small amount and rubbed it on her skin. There was no need to apply it directly to the area that would be affected; the dust took care of that on its own.
Though, she did that for a second reason. While true that there was no direct contact needed, the dust would work much faster when done so. For example, this dust would make her breasts grow bigger. If she really wanted to get immediate results, then she’d have to take off her bra and apply the dust on her naked boobs. But Blake had other plans.
She wanted the growth to be less noticeable for now. Later on it would certainly be noticed, but revenge was a dish best served cold, wasn’t it? Blake had it all planned out.
The dust was gone in an instant; immediately absorbed into her bloodstream and ready. Blake was satisfied with what she came for. After carefully placing the used dust and equipment away where it belonged, she sneaked out of the classroom again, but not without her own brand of dust. One by one, each vial was stored in a bag. She would need to hide the small supply somewhere. Probably a place where her teammates wouldn’t start looking.
Blake contemplated on a good hiding spot, almost reaching the dorms, when she noticed a lone figure wandering the hallway. Her amber eyes lit up as she found her solution.
“Jaune, can I talk to you for a moment?”
The blonde knight stopped in his tracks, turning around to give her a polite wave. “Hey, Blake. How’s it going?”
“I’m doing fine. Thank you for asking.” She smiled somewhat, trying to be as friendly as possible. Knowing him, however, it would be easy to get what she wanted. “I want to ask you for a small favor.”
“Well, anything to help out a friend. What’s wrong?”
Blake held up the bag of dust for him to see. “Today I bought some special dust, but forgot that there isn’t a lot of space in my room to store it away. Between Ruby’s comic books, Weiss’ own dust, and Yang’s hair products, there really isn’t any spot I could put it. Not to mention it might get mixed with Weiss’ dust, or an accident could happen because of Ruby. Do you see what I’m getting at?”
“Ha, I think I do.” Jaune chuckled and nodded. “Don’t worry; I’m not that much of a doofus. Sure, I’ll gladly keep an eye on it for you. And you don’t need to fear Nora accidentally using it or anything. Last time she did that with Pyrrha’s, she got a stern warning from Ren, so now she stays away from other people’s dust supplies.”
Did she feel bad for taking advantage of his kindness to cover up her little plot? A little, admittedly. But Blake was too invested in this to care.
“Great. I appreciate your help. I’ll see you later, then?”
“Yeah, see you later, Blake.”
And as the leader of team JNPR entered his own dorm room with the bag of dust in his hands, Blake smiled a predatory grin.
…
“Ugh, I’m so glad the day is over.” Yang sighed dramatically. Her teammates rolled their eyes, watching the brawler throw herself on her bed with reckless abandon. “Oobleck’s lessons are killing me. Either his or Port’s. Seriously, one goes way too fast to understand anything of what he’s saying, and the other makes you fall asleep faster than counting sheep.”
Weiss held her head up high. “Well, at least someone was taking notes and could keep up. Don’t come to me for any copies either; just so you know”
And there was the typical Schnee arrogance, Blake idly noticed. The faunus student tried to ignore the haughty attitude that Weiss was showing. Instead, she moved to get changed like the others. No doubt the girls would be surprised in a few seconds…
After all, the dust had worked wonders throughout the day. Subtle as it might have been, Blake knew what to look for and what to expect, and she’d kept an eye on her bust the entire team; at lunch, during class and even now. Her shirt had gotten tighter, and her bra fitted a bit more snugly as well. Blake smirked in delight. Luckily her jacket helped conceal her progress.
“Right, Blake?”
The sudden voice broke her out of her thoughts. “Hmm? Oh, sorry. I wasn’t listening.”
“Yang was asking if you agreed that Oobleck needs to take it easy.” Ruby clarified.
“Sure, why not.”
“Betrayed by own partner!” The petite girl’s more buxom sister wailed dramatically.
The group calmed down after that, and began to prepare themselves for a good night’s rest. However, for once it would be Blake who would shake things up a little. It was finally time to put the next phase of her plan into motion.
“Yang, do you mind lending me one of your bras?” She asked innocently, turning around with nothing on her upper body save for her normal one; a modest C-cup.
The brawler blinked. “Huh? What do you mea—wow! Uh, sure thing. Let me take a look real quick.”
Both Ruby and Weiss were now interested in what was happening, and they were equally surprised by Blake’s sudden bust increase. The latter’s shock and indignation was exactly what she had hoped for, though she was careful enough not to show it.
“Wha-- how?” Weiss’ eyes were filled with jealousy as she openly gawked at Blake’s boobs.
While not exactly larger than Yang’s, her expanded tits were noticeably an entire cup size larger. Their shape was still perfectly round, but they looked fuller and had more volume. The dark bra was no longer enough to contain her breasts. Bits of titflesh poked through from underneath and at the sides. Blake took pride in how her bust was almost on par with Yang’s legendary chest. Just a bit more and they would be equals.
And more importantly, they’d be even bigger than Weiss.
“I suppose I went through a growth spurt.” Blake shrugged idly. Her carefree manners seemed to annoy the heiress even further. “Honestly, it’s not that uncommon. We’re still growing, after all. Or at least, most of us.”
Even Ruby winced at that last remark. Yang hissed loudly, muttering the word 'burn' almost inaudibly. But they weren’t the ones whose cheeks flushed red. Blake watched victoriously as Weiss immediately went to bed, clearly not in the mood for any kind of conversation.
"Sheesh, that was cold, Blakey." Yang grinned, amused by the display. "Seriously though; looks like they grew a lot."
Blake was smug, slightly squeezing her globes together with her arms. "Looks like it. Still, I think I'm nowhere near done."
Soon enough they were all fast asleep, except for Blake. She was too busy celebrating her victory by patting her grown tits, a pleased smirk ever present on her gorgeous face.
