Team RWBY's dorm room was so quiet you could hear the pages being turned by Ruby, Weiss and Blake and Yang's fingers tapping on her scroll. On this quiet midweek afternoon, there was nothing but peace and quiet in the room until Blake spoke up from her bunk.

"Is it just me, or is the milk at Beacon kind of sub-par?" she idly asked.

"Thank you!" Ruby exclaimed, throwing her arms in the air, almost punching the roof from her top bunk. "I thought I was the only one who noticed."

"I've noticed that too," Weiss responded, setting her book down on the desk she was working at. "I even started having my coffee black with how bad it is."

"Wait a second," Yang interrupted, finally pulled from her scroll. "Aren't you rich enough to buy your own milk? Hell, I'm sure your Schnee Money could buy a whole farm."

"Maybe my father could buy a farm, but I certainly can't. And while I could buy my own milk, I don't exactly have a lot of opportunities to go into Vale, let alone to do grocery shopping. That, and any milk that could be mailed here might actually be worse than what we already have," Weiss answered.

"And I don't think we can bring a cow to Beacon. I'm not even allowed to have Zwei in here," Ruby added, with a beeping alarm interrupting her. Ruby checked her scroll, making her eyes open wide with shock. "Oh geez, I gotta go. I was gonna go hang out with Penny. Let's talk about this later, bye!" she said as she clambered off her bunk and shot out the door. After a moment of silent thought, Yang jumped down from her own bunk.

"Alright, so, what Ruby said gave me a crazy idea. We might not be able to bring a cow to Beacon, but we could… make one," Yang suggested, garnering raised eyebrows from the monochrome pair.

"I'm not sure what you're getting at," Weiss responded slowly, thinking as she spoke.

"It'd be easy. I'd take some stuff to make me lactate and then I'll provide all we need," Yang said with full confidence.

"You're right, that is a crazy idea," Blake deadpanned.

"That only sounds slight less practical than bringing a cow to Beacon. Also, I doubt you can provide enough for four people," Weiss added. The pair's comments gave Yang a momentary pause.

"Well, it was just an idea, can't say I blame you for not being into it," Yang replied with a nonchalant shrug. 'Guess I'll just have to prove them wrong', Yang thought as she whipped out her scroll and started doing her research. Before long a pair of private messages from her teammates appeared on her scroll.

Weiss: I apologise for doubting your idea, but I have to admit that I am curious. Let me know if you are still interested. Please do not tell anyone.

Blake: Sorry for saying your idea was crazy, I didn't want Weiss to think I'm into this idea. Do you still want to try it?

As she read the messages, a devilish grin crept on to her face. 'This'll be fun.'

That weekend Yang had her concoction set up and ready to demonstrate for Weiss and Blake. Of course, the two girls were unaware that the other would be joining them, with each of them silently waiting for the other to leave before Yang arrived. That was when Yang strolled on in with a little bottle in hand.

"Alright, ladies, you ready for this?" Yang said, confident as can be. A flurry of emotions hit Weiss and Blake's faces, primarily panic.

"I-I-I have no idea what you are talking about," Weiss unconvincingly defended. Blake kept silent, but her face said everything it needed to.

"I dunno, this message you sent me says you know exactly what I'm talking about," Yang said with an almost insufferably smug smirk. "But don't worry, nothing from today is gonna leave this room, assuming you two can keep a secret." Blake responded with an almost frantic nod, while Weiss's response was more subdued, yet equally in favour. Yang ditched her jacket and sidled on up next to where Blake was sitting on the edge of her bed, beckoning Weiss to join them.

"Do we have to watch? I can't imagine it being that quick," Weiss said as she sat down.

"Well, assuming I wasn't a victim of false advertising, I'm about to prove you wrong," Yang said, yet to ease off the smug. She opened up the bottle, filled the cap with the neon liquid and downed it in one swift motion. "And now we wait."

The gasp that escaped Yang's mouth moments later made it clear that this wasn't going to be a long wait. Her tube top began to stretch as her breasts grew beneath it. Within moments Yang's bust had gotten so big that they began to spill out the top of Yang's top, with the quiet strain on the seams of the top barely audible, but increasingly visible, as small patches of flesh became visible between gaps in the seams. Yang quickly shoved her top down to save it from bursting, revealing a strapless bra that was equally snug, with flesh spilling out everywhere it could. She immediately reached back and undid the clasp of her bra. The tension immediately faded for Yang as her breasts were freed from their restraints, revealing that her nipples had grown larger and firmer, while having turned a darker brown colour.

"Oh, wow, this is way faster than I expected," Yang breathed.

"I didn't even know this was possible," Weiss added.

"It's incredible," Blake said with a rapturous tone.

Tension began to build in Yang's chest again, as her soft chest began to perk up and grow firmer, filling out into a rounder, more taut shape.

"Uh, guys, I think they're getting full. Did you guys bring anything to… uh…" Yang said, nervousness creeping into her voice.

"I thought you did!" Weiss interrupted in a panic.

"I have an idea," Blake said, focused and collected as she leant in and latched on to one of Yang's swollen nipples with her mouth. As Blake began to suckle, Yang felt waves of pleasure and relief emanate from where Blake was attached. Yang couldn't relax just yet though, as a white bead began to form on her other nipple.

"Hey, Weiss, I know this is a lot to ask, but can you help me out before I start leaking?" Yang asked, almost pleading with Weiss.

"Tell. No one," Weiss said firmly, eyes locked with Yang's. She then looked at the free nipple, from which a very small trickle of white liquid had begun. Slowly and reluctantly, Weiss lapped up the trickle before latching on and suckling on Yang's erect nipple. With both milk-laden breasts being dealt with, Yang gently rolled her head back and let out a long moan of contented pleasure.

"Oh my gods, this feels so gooooood," Yang gasped as her arms almost instinctively reached around to cradle Blake and Weiss's heads as they fed from Yang's bloated breasts. While Yang wouldn't fully admit it out loud, there was a warming in her core that was telling her just how incredibly aroused by this she was. She made a mental note to deal with that later and let Blake and Weiss carry on. She kept on letting out shorter, quieter moans and gasps of pleasure as her newly sensitive breasts were suckled and fondled by Blake and Weiss, Blake being the more enthusiastic of the two by far.

After an amount of time that Yang wished could go on forever, Blake detached herself from Yang's breast, which had finally deflated back to its normal size, something that Yang hadn't even noticed in her pleasured haze.

"So, how was it?" Yang asked, blushing slightly.

"I… I really don't know how to describe it, but it was amazing," Blake said reverentially. As if on cue, Weiss finished her drink too and let Yang's other breast be free.

"That may be the best milk I've drunk in my entire life," Weiss said, almost sounding confused at the words coming out of her mouth. A beaming smile rose to Yang's face as she wrapped the pair in a big hug.

"Oh, I'm so glad you guys enjoyed it," Yang cheered. "We gotta do this again, except, y'know, better organised."

"I am in full agreement with you. Maybe you and Ruby will actually be able to drink some of the next batch," Weiss stated.

"I really, really want more," Blake said desperately.

"Don't worry Blakey, there's a whole lot more where that came from," Yang answered with a winning smile.

[AN: I'll probably turn this into a multi-part thing, but not a lot of parts. Expect maybe another three or four parts, depending on how these ideas go and whether I get distracted writing other stuff]
