[Instant Loss, Lactation, Brain Drain]

"What a peaceful summer day. Wouldn't you say, my dear Byleth?"

"It's nice. Are you holding up alright, Rhea?"

"Of course, my dear. As long as you're with here, I'll be as right as rain. As long as I can see your adorable face, that won't change."

Rhea, the Archbishop of the Church of Seiros, and one of her closest confidants, the mercenary-turned-teacher Byleth, were spending a bit of their free time sitting upon a rather unremarkable beach, just letting the sun shine down on them and bless them with the warmth that they had earned. Sure, this wasn't their own world, they had been rather rudely pulled into some sort of mishmash between the many worlds that possessed the so-called Fire Emblem... But that didn't matter when they had one another.

At least that's what Rhea thought. Byleth's emotions were much less elaborate. She liked the sun shining down on her. And she liked that Rhea was here with her. That's all she really needed to smile ever so slightly. She wasn't good at smiling, though she never knew why. But it was a bit easier with the green-haired matron sitting this close to her, breathing down her neck.

But nothing would last forever. This peace that they had been dealt would be swept aside as they heard the sound of something driving towards them. It wasn't a carriage, much less the strange machines that one of the other Kingdoms were able to use. So what was happening behind them, exactly?

Rhea and Byleth looked behind them, only to both raise an eyebrow as they laid their eyes on a mostly white four-wheeled vehicle with a single hand clenching the earth sprayed onto its side. It seemed utterly unremarkable, aside from the fact that it didn't seem to be moving using traditional methods like horses or magic. It seemed entirely automated, prompting the two ladies to get up and approach it to try and figure out what they were looking at.

"There you are! Took me long enough to find you, I thought you'd be back home at your Monastery, but you've wandered all the way out here? Sheesh, give a boy a break, will you?"

Rhea and Byleth both turned to look at the driver who leapt out of the window of the truck, a young man with bright white hair and sharp red eyes. Combine that with the suit he wore, and he only added to the strangeness of this entire situation. No matter, they could find a way to deal with him and deal with all of this. They were adults, after all.

"Excuse me." Byleth spoke as she kneeled down to look the boy in the eye. A boy that was about half her size, which meant that his eyes had already gravitated towards her rather large assets before she had even started speaking. "Who are you? What is that vehicle? And why exactly were you looking for us?" She asked the obvious questions, questions that made her green-haired companion pull her back up to her feet.

"Byleth, sweetie. I know he's a cute little thing and all, but that doesn't mean you can just trust him. There's something about him that rubs me the wrong way." Rhea whispered into the teacher's ear, before bending over a bit as she let go of her and talked down to the short boy. "Sorry about that, sweetie. Why don't you tell us a little about why you came here? I'm sure that we can figure something out, if you've been trying to find us."

The boy's eyes gleamed ever slightly as he grinned. "Oh, nothing, really. I was just looking for you two cows. Cow 24 and 25, right? I think I have your numbers right." The boy said as he pulled out two pictures that he showed to the two ladies, letting them identify themselves. "That's you, right? I'm not getting this wrong?"

It did seem like he was getting it wrong at a simple glance. Sure, it was definitely a picture of them, but their tits were way bigger than their heads, and despite the fact that they were clearly wearing their color-appropriate bikinis, the versions in the pictures were wearing cow-themed bikinis. Not only that, but Cow 24 and 25 were definitely not marked with a number right above their wombs nor a tag in their ears. That was just wrong.

"You must have the wrong cows." Cow 24, the woman formerly known as Rhea, smiled as she handed the picture back to the young boy. "But I'm sure you'll find them soon. They should be around here somewhere, shouldn't they, 25?"

Cow 25 nodded as she handed the picture back. Strange, it felt like something was even more off than her fellow cow implied. Maybe they were just backed up a bit. Nothing that a bit of mutual milking couldn't help with.

"Are you kidding? You two really must have brains full of milk, because that's you two!" The boy cried out as he grabbed ahold of one of their respective tits, tugging a bit. "Now quit acting like you're anything but cows and get ready. I didn't make this damned company just so my cows could go out and act like humans!"

As the young boy grabbed ahold of their nipples, a powerful shock pierced through the two women, and the moan that left their lips could only be described as orgasmic. Especially since their pussies were on the verge of flowing over with how much cum they had been drooling. Silly cows.

Both Cow 24 and 25 responded positively to their owner's tugs as they put their hands behind their stupid heads, all while letting out more and more mooing moans as their tits rapidly started to expand until they weren't just as big as the tits that were in the pictures, but even bigger. That's right, those pictures were from when they first accepted their roles as Cows. They had grown to at least double the size at this point, it was a wonder they hadn't fallen over from how heavy they were!

Of course with that heavy load on their chests, their brains rapidly started to take hits. They were stupid Cows after all, they only had milk for brains. So as soon as they started to leak from their owner tugging and making them squirt lots of that precious milk, the milk inside their heads started to drain into their titties to make sure that they were topped up.

Cow 24, being the more mature of the two Cows, giggled as she started to finger her other nipple. She hadn't even noticed that her bikini had turned back into her incredibly flimsy cow duds, as she pierced straight through the useless fabric and played with her nipple. It felt so good to try and milk herself, but she stopped once her owner slapped her tit and made her moo as more of her milk leaked right down into those tits.

Cow 25 was... Really backed up. She wasn't used to being milked, in fact she could feel her consciousness trembling in balance. She wanted to be milked. But she knew that if a Cow like her, who had never before been milked, went through the euphoria of having her milk drained from her udders? She would break completely. And... And that was something she wanted to save.

"Right, you two have both wasted my time way too much by going all the way out here." The owner scoffed as he walked around them, slapping both of them on their respective asses, making those cheeks bounce around and make their Atlas Corp tattoos more apparent in the process. "Get in. We're speed-milking you two and getting you back to your stalls.

The stupid Cows saluted as their owner gave them an order, squeezing into the back of the truck as they noticed two large suction cups waiting for them. They were big enough to fit both of their tits inside, meaning each cow only got one. Not that they cared. They were Cows! The fact they got to be automatically milked dry was a privilege!

Cow 24 and 25 let out yet another moo as their owner stuffed their fat fucking number-branded tits into their respective cup, the look in their eyes growing dimmer and dimmer the more their tits got stimulated. It felt like they were forgetting something important. Something that they had been born to do. And how this was all sorts of wrong. But at the same time, they were Cows. They were probably just thinking of the kind of dreams that they had that made them feel human. Silly Cows.

"Alright. Brace yourselves, stupid Cows, because you're gonna be completely brainless once this thing's done." Their owner said as he shined a grin, and the two stupid Cows just stood there on all fours, already brimming with anticipation as they couldn't wait to feel their brains sinking straight into their boobies and out through the cup.

He didn't give them a chance to properly brace themselves before he switched the machine on. And the suction was fierce, the two Cows letting out so many moos that you could get lost in them with how loud they were. All while their expressions melted from stupid to completely mindless as they couldn't stop themselves from losing everything that made them human.

Cow 24 didn't even think about the fact that she had once been an Archbishop. Nor did she think about the fact that she was a Dragon at heart. She was now nothing more than a Cow. Her tits were growing the more they were being sucked on, so much milk pouring into the tube at the end of the cup. She even started to roll her eyes back into her head, those very same eyes spinning and spinning until they ended on a matching pair of Cows as the rest of her brain drained right down into her tits, leaving her completely and utterly stupified. And the drooling puddle underneath her happened to show where any stray thoughts had gone, the stupid cow cumming the rest out when she wasn't busy letting it pool into her tits as saliva.

Cow 25 knew nothing about her true origins. And they didn't matter now that she felt her mind draining straight into her tits, making them explode until they were three times as large as her head. Because she was too busy mooing the rest of her life away, cumming and drooling in tandem as her eyes turned black and white repeatedly until her irises zoomed out and revealed themselves to be spotted cows. She was just as stupified as the former Archbishop, though the incredibly mindless smile on her face happened to be even stupider due to her previous inability to properly emote. It was truly a sight to behold.

As the two Cows continued to cum everything away, the boy that had claimed ownership of them carefully looked at the many bottles that were starting to be filled at the other end of the tube. A whole dozen bottles were ready to be shipped, and they weren't even close to empty. All he had to do was slap their dignified faces onto the bottles and sell them as high quality milk. Then the Cows would do the rest.

"You know, I expected less of you two." The owner said as he slapped their tits, making them both moan. "But even though you've been free range, you're still giving me a whole lot of milk. Good work, Cows. Your Rhea and Byleth milk will bring me so much cash that I can afford another bath. And you two get the same crummy stalls as always. Doesn't that sound good to you two stupid Cows?"

Cow 24 and 25 would nod if they could hear him. But no. They were just happy to be milked. That was their sole purpose in life. Even as they were driven off to a facility, never to be let out of their stalls ever again...

They were happy little stupid cows, mooing their lives away…
