The Dairy Cow Procedure
A tingling sensation spread across my breasts, coated in the carefully applied liquid. It gradually grew hotter before finally fading away completely, leaving no feeling at all.
“How is it?”
Maria pinched my nipple with her fingers, but I felt nothing.
“I don’t feel anything at all.”
“The medicine I just applied softens the cells while simultaneously acting as an anesthetic.”
“Here’s the slime,” Isabel said, handing Maria a small, white slime from a round container.
Maria kneaded the squishy slime moving in her palm, splitting it neatly into two portions. She then pressed each piece against my nipples. The slimes clung to my skin for a moment, as if examining the surface, before slipping along the milk ducts and beginning to burrow into my breasts.
“It feels similar to when I first received the dairy cow treatment.”
“The method is exactly the same. Only the technology has improved. We loosen the breast tissue, inject the slime, and help it settle properly. That’s all there is to it.”
Maria gently massaged my breasts with both hands to help the slime spread evenly through the ducts. Despite her small frame and tiny hands, her practiced movements skillfully worked the breasts that couldn’t even fit entirely in her grasp. Through her glasses, I could see the milk ducts fusing with the slime, becoming denser and expanding in volume.
After massaging my breasts steadily for a long while, Maria wiped the sweat from her forehead with her arm and spoke.
“Phew, it’s been so long that it feels more tiring than usual. The fusion should be complete by now. It doesn’t hurt, does it?”
“No, I still don’t feel anything.”
“It’s a new, heavily improved slime, so that makes sense. Now it’s Isabel’s turn.”
While Maria applied the anesthetic to Isabel’s breasts, a piece of knowledge suddenly surfaced in my mind. Breast milk is produced when blood is filtered through the mammary glands. Since I was a full-body prosthesis that used artificially manufactured blood rather than normal human blood, I wondered if I could even produce proper breast milk.
“By the way, can normal breast milk be produced using the artificial blood that flows through my body?”
“The artificial blood used in full-body prostheses contains all the necessary components for producing breast milk, with the sole exception of genetic factors. There’s virtually no difference from regular blood in that regard.”
“I see. That makes sense.”
Since I knew so little about the technology used in my own body, this was the first time I had learned that fact.
Maria finished massaging Isabel’s breasts and, with slightly trembling hands, picked up another device.
“All dairy cows must have their dairy cow registration entered into their ear tag.”
“We don’t need to attach anything extra, right?”
“The ear tags for mares and dairy cows are identical, so we just input the data.”
The dairy cow registration was completed very simply. All it took was entering the information into the device and holding it against the ear tag to transmit the data. Since Isabel didn’t have an ear tag yet, it took a little longer to attach one.
I was fiddling with the ear tag now dangling from my left ear when Maria, while cleaning up, said,
“From now on, when the handlers scan your ear tag, both your physical information and dairy cow data will be displayed.”
“How long will it take until I can start being milked?”
“It varies by individual, but the premium-grade slime we used on you only needs to be milked about once a week.”
“I don’t think I’ll be able to visit the park that often.”
“Regular milking is ideal, but it’s not a problem even if you can’t empty them completely. The slime will reabsorb any aged milk and convert it back into nutrients for your body. That way, it always maintains a fresh state.”
“It really has advanced a lot.”
In the past, even when breasts were completely full, milk production would continue without stopping. If you didn’t milk them regularly, it would become incredibly painful. Now, the system had reached an astonishing level where it could automatically reabsorb old milk and manage freshness on its own.
“It’s a technology that greatly reduces the burden on dairy cows and has played a major role in popularizing the practice. Impressive, isn’t it?”
“I’m genuinely amazed.”
“On top of that, we developed nutritional supplements specifically for dairy cows that promote milk production and ensure a steady supply.”
“So that’s why they were milking cows on the spot at the milk shop.”
I could clearly feel how much tremendous effort had been poured into this from every angle.
“The dairy cow business is one of Eden’s most important industries. Our goal is to convert all the angels into dairy cows and establish a steady export stream to the neighboring countries.”
“Turning over twenty thousand angels into dairy cows must keep you busy.”
“We’re short on manpower and the budget is tight. Since it’s a national project, it’s difficult to bring in private capital.”
“Unlike the mares, dairy cows need to remain Eden’s exclusive asset, right?”
“Oh? You understand well. You really have gotten smarter.”
For some reason, I seemed to hear people telling me I had gotten smarter quite often lately. Was I really that stupid in the past? I grumbled internally that it couldn’t have been that bad.
While I was thinking that, Isabel approached, touching her now firmer and more perky breasts.
“For Eden, which possesses almost no material resources, the answer lies in making maximum use of human resources. That applies to both the prostitution industry and scientific research. Once milk exports stabilize, we expect it to provide significant support to Eden’s finances.”
“That’s true. We can’t hold neighboring countries hostage with technology like we did in the old days, so we have to pioneer new paths.”
In the past, when God ruled Eden, the city had carried out inhumane experiments and acted like a technological thug nation, using its extremely advanced technology as leverage to extort money from neighboring countries. While it had brought in a great deal of wealth, Eden’s reputation among the surrounding nations at the time had been quite poor.
Isabel quickly dressed herself again and spoke to me.
“By the way, why are you still naked? You can put your clothes back on now.”
“Ah, I’m so used to being naked in the lab that I didn’t even think about it.”
Ever since my days as an angel, I had been treated as an experimental subject so frequently that being naked felt more natural the moment I entered a laboratory. It was only after Isabel pointed it out that I began searching for my underwear and putting it on.
Isabel, who had been staring intently at me, pointed at my parasitic tentacle tail and asked,
“With a tail like that, can you even wear underwear?”
“That’s why I usually don’t wear any. Pants are uncomfortable too, so I only wear skirts.”
Even now, I was wearing a skirt that reached mid-thigh with nothing underneath. My parasitic tentacle tail slipped out from beneath the hem, curving gently upward.
Upon hearing my answer, Isabel clapped her hands together.
“Wow, so that means your pussy is completely visible under the skirt? That’s so lewd~”
“Honestly, I need a bra because it helps stop my breasts from bouncing around, but I don’t need panties. My body doesn’t secrete any fluids, and even if it’s exposed, there’s no real problem.”
“Ehh.”
Isabel suddenly approached me as I was putting on my top and flipped my skirt up. Of course, my fully exposed crotch came into view, and she laughed as she spoke.
“It’s still that neatly closed, pretty pussy. It matches perfectly with the succubus pattern on your lower abdomen.”
“Thank you.”
“Still, you should cover it. Especially if you’re wearing a skirt. There’s such a thing as the dignity a human should maintain.”
“But wearing Las all the time would be uncomfortable for both of us.”
“Hmm, I’ll modify some dairy cow underwear for you. Just wait a moment.”
With those words, Isabel disappeared into the deeper part of the laboratory.
Maria, who had finished cleaning up, saw Isabel running off and asked,
“What’s going on? Why is she running like that?”
“She said she’d make me some underwear and told me to wait.”
“Huh? Ohhh, you mean the dairy cow underwear. Since Elisha will be living outside, there’s no real need to prepare any for her.”
“Dairy cow underwear… you mean the kind the cows in the park were wearing?”
All the dairy cows here had been completely naked except for their underwear. The top piece only consisted of a section supporting the underside of the breasts and a band wrapping beneath them, leaving the nipples and upper portions of the breasts exposed. It existed purely to stabilize the breasts. The bottom piece was even more peculiar. It left the anus completely uncovered and consisted only of a metal section covering the crotch, secured solely by straps around the pelvis. These unusual undergarments seemed designed to make it easier for the handlers to manage the cows.
“That’s right. They were developed specifically to make it easier for handlers to manage the dairy cows.”
“She saw my tail and thought I might need them.”
I lifted my skirt and showed Maria my crotch and buttocks. Rather than being unbothered, Maria looked genuinely horrified by my shameless behavior.
“Put your skirt down right now. Aren’t you embarrassed? I don’t understand why succubi have no sense of shame whatsoever.”
“Since when have you cared about that? You received training from QA and Kyubey too, so you don’t have any aversion to exposure either.”
“I had to undergo re-education because I frequently appear in official settings. My values regarding clothing and exposure are those of an ordinary human.”
“Aww, that’s a shame. I thought the Maria who wore lewd outfits without a care was really cute.”
No wonder she only wore dresses with almost no exposure. It was because of the re-education. After all, as the ruler and public face of Eden, appearing in official settings while shamelessly exposing herself would cause problems.
Seeing the clear heart shape in Maria’s pupils, I suddenly thought of Ruya, who must be with her family right now. Since she was the first slave I had created myself, I felt especially attached to her and worried about her. I wondered if she was doing well.
While I was chatting with Maria over tea and snacks, Isabel came running back with underwear in both hands.
“I’m done! Exclusive dairy cow underwear for Lady Elisha.”
“Thank you for your hard work. You even made the top piece?”
“Since I was making them, I figured they should match as a set. Here, try them on right away.”
At Isabel’s urging, I took off my clothes again, and she began dressing me herself. First, she positioned the top piece under my breasts and pushed it upward, then secured the support band that wrapped just beneath my chest right above my waist. She pulled the fastening straps tight and locked them in place.
“Ohhh, this really supports and holds my breasts firmly. It feels incredibly comfortable. And there are no shoulder straps, so it’s even better.”
“The weight of a dairy cow’s breasts isn’t just from their size. The milk makes them far heavier than those of ordinary women, so normal bras can’t handle them. That’s why we developed these specialized undergarments that distribute the weight and make them comfortable.”
“Amazing. It’s much more comfortable than I expected.”
Thanks to the undergarment’s support band firmly anchored around my ribcage, my heavy breasts were held securely in place. Even when I jumped on the spot, they barely bounced, dramatically reducing the feeling of weight. I had thought my usual bras fixed my chest fairly well, but compared to these garments developed for a special purpose, they were nothing.
“It’s made from shape-memory material, so the longer you wear it, the more it will adapt to the wearer’s exact breast shape and size before locking in. That makes it even more comfortable. It truly is custom-made underwear.”
“I love it. From now on, I’m only going to wear these.”
I moved my body this way and that as I spoke. The breast support only reached just above my waist, so moving my torso felt comfortable too.
Maria, who had been watching me with a pleased expression, smiled proudly.
“If I had known you’d like it this much, I would have given it to you much sooner.”
“Wouldn’t this sell really well to women who suffer from having large breasts?”
“The production cost is too high to sell commercially. It uses quite a few cutting-edge technologies.”
After listening to Maria, I realized it would indeed be difficult to sell these on the market. Even with simple consideration, the price of the materials and the complexity of the applied technology would make mass production difficult, meaning the unit cost would be very high.
“I didn’t even consider the low demand factor.”
“Women with breasts as large as a dairy cow’s probably don’t even make up the top 0.1% of the population. The market wouldn’t form in the first place.”
“And they’d be too expensive to make to order. It’s a shame in so many ways.”
“Alright, now it’s time for the bottom piece.”
Following Isabel’s instructions, I lifted my legs to help her put the underwear on me. The garment, perfectly sized and shaped to cover only my crotch except for the area with the clitoral ring, clung tightly to my skin the moment it touched. She then lifted the straps, hooked them over the protruding parts of my pelvis, and pulled them hard before releasing. The underwear automatically tightened and locked itself in place.
“How is it? The tail doesn’t get caught, right?”
“Yeah, it’s only covering my crotch perfectly.”
“Originally, these are chastity belt-style undergarments.”
“Ah, that’s why it felt familiar. It’s very similar to the chastity belt Elisa used.”
Other than the added straps, it looked remarkably similar to the chastity belt I had worn to prevent sex while pregnant with the bioroid that would become Elisa’s body.
“Wait, then is this a chastity belt too?”
“Normally it can only be removed with a handler’s permission, but I removed that function so you can take it off yourself.”
“That’s a relief.”
With Dahgon and Zadin frequently using my pussy, a real chastity belt would have been problematic.
“All the other functions besides the chastity feature are intact. It has vibration and orgasm denial capabilities.”
“Why did you add such scary functions?”
“They’re rewards and punishments given by handlers to dairy cows. Because of livestock conversion brainwashing, their instincts become stronger than reason. This method is very effective for controlling them.”
When Isabel took out a small device and operated it, the underwear began vibrating on its own. The subtle stimulation at just the right intensity made my legs instinctively press together.
“Ah! Is that the controller?”
“Yes, it’s exclusively for you, Lady Elisha. There’s no locking function, so it isn’t forced, but it’s perfect for enjoyment, don’t you think?”
“Mmm.”
The vibration provided pleasure at a moderate intensity, and there was even an orgasm denial function that sensed an approaching climax and stopped right before it. It really was underwear well-suited for regular enjoyment.
I learned how to use the controller from Isabel and tried operating it myself.
“Ugh, you can even adjust the intensity. And this is the orgasm denial function.”
“I’m glad you like it. To remove it, just pull both straps at the same time and release.”
“Thank you.”
“Elisha, I don’t have much time. We should head out soon, so get dressed.”
“Ah, yes.”
At Maria’s words while she glanced at the clock on the wall, I set the vibration to the weakest level and put my clothes back on over the new dairy cow underwear. After receiving Isabel’s farewell, we walked for quite a while again, left the underground laboratory, and returned to the surface.
“Oh no, it took longer than I expected. We might be late.”
“Really? Here, get on my back.”
I knelt down in front of Maria, showing her my back.
“You’re going to carry me?”
“When else would I use a mare that runs so well? Hurry up.”
“Thank you, Elisha.”
I immediately began running lightly across the park grounds with the light Maria on my back.
“Thanks to the new underwear, there’s less bouncing, so it’s easier to run. I’m going to pick up the pace now, so hold on tight.”
“Okay.”
Feeling Maria’s slender arms wrapped firmly around my neck, I put real strength into my legs.
