A few hours later, when night fell even more across this pleasant little village, Sekh and I were cuddling in bed. She wrapped her arms around my chest and rested her head against my shoulder. Niva hugged a clone version of my slime form. Her smile was so big when she petted it, and I was happy for her. Pulling out the songleaf from [Storage], I started to play a rich, airy melody. It was poetic in nature—collecting and distributing a wafting, ethereal tone with highs and lows across this extravagant mansion. Perhaps that was the very definition of irony? Especially considering my true nature being of an abominable monster hated by the world for simply existing and being able to play this enchanting song?
Did it matter? Playing it soothed my heart.
Once I was done, I stored the leaf away and cuddled with Sekh after she complimented me on my performance. After a few seconds, a random thought came to my mind about the AI. When asked if it could ‘read,’ I was happily informed it was literate. Even more incredible was that, with my permission, it could ‘upload’ the information to my mind as a form of photographic memory. If that was too invasive, it could connect my mind to a databank created within the AI’s information database. If that didn’t work, the AI told me I could leave everything to it and query it for what I needed. And that was probably the best way to go about this. But I was going to try the other ways once it had some info.
With that in mind, I headed to Murag’s room to store as many of his tomes as possible because I had the space after using those cores. There were still about 200 books left, but I had more than enough. The AI was given the command to read through everything as I slipped into bed and cuddled with Sekh.
Somehow, the conversation turned lewd and involved slime. I already knew I could form it into things and break it off, but using it for sex? Sekh and I experimented a little bit, and it took a few attempts to form my slime into a rectangular shape slightly longer and girthier than my penis. Sekh held it in her hands and squeezed it a bit while I pulled off the covers and jerked off. However, I returned my penis to its original length and watched as Sekh grabbed my dick with one hand while pushing down the slime sex toy with the other.
I think these things are called onaholes.
Biting my lip, I lightly moaned as she continued to push it down until my whole penis was completely covered. The slime was so squishy and blubbery, but it had little folds ribbed around it. Sekh licked her lips when she pulled the slimy fuck toy off my penis. “Oh, fuck... That feels good~~~” She moved her hands faster, alternating between hasty and deep, slow strokes. Before I knew it, I thrust my hips to match her handjob and came without warning. Thick ropes of semen ejaculated up, filling up the slime until the forest green had a solid white interior.
“That’s a lot,” Sekh noted when she stared at the onahole. Thanks to how it was made, semen couldn't leak out of the bottom. Exasperated and out of breath, I stared at Sekh with pleasured-filled eyes, wondering what her next move was.
Never did I expect her to touch the slime to her lips and drink my semen as if it was a nutritional drink. My sperm dribbled down her chin and onto her breasts, but she continued swallowing until it was empty.
“It’s always so delicious,” Sekh seductively whispered. She was always so erotic, even when she didn’t mean to be.
I jerked off while staring at her beauty, and she seductively crawled across the bed to kiss me. She played with my tits, her hands molding them as if they were putty. They felt heavier than usual... And then a familiar feeling came across me as warm, creamy milk flowed from my nipples, covering Sekh’s soft palms...
“Milk...? Breast milk...?” Sekh’s tail quizzically slithered across the bed as she licked her fingers. I felt this same feeling when the clone’s mana returned to me but experiencing it in the flesh?
It was...nearly indescribable. My boobs felt hot and full. Sekh cautiously put a hand on my nipple and slightly squeezed, causing me to cover her stomach with semen as I climaxed. It was like tiny needles danced across my breasts, but the warm, hot feeling never left me for a moment as my lactation continued.
“Damn, that’s a lot more than the clone. Hey, Big Tits. Drink it up good, and maybe you’ll have some honkers as big as her... Wait... On second thought, don’t. Those fat udders don’t need to get any bigger, hahahaha!” Tilde laughed, but I saw her groping her lacking chest. “But for real. Cowfolk milk is, and I’m being serious here, way better than milk from an actual cow. It’s higher quality, has way more nutrients, and if you’re sick or recovering, a nice glass of Cowfolk tiddie juice is just what the doctor ordered. And I’m being a thousand percent serious, Master.”
“So... You’re saying Niva should drink my milk? Would that help her recover faster?” Tilde nodded, then stated I could mold my slime into a bottle, then stash that within [Storage]. Items placed within would never go bad, after all. “Niva? It’s up to you, honestly. I won’t force you to do anything.”
“Ahhh...” She opened her mouth to speak, but only mere sounds flowed out. She quickly nodded, though, and pointed to her wounds with her remaining hand.
“I guess that’s that... Sekh?”
“Hmm?” She stared at my face.
“Can you...milk me?” I quickly crafted two slime bottles with one hand and moved Sekh’s fingers with my breasts with the other.
“My liege...” She softly repeated. She grabbed one of the bottles and placed it around my nipple, then had me turn around until I leaned my back against her chest. Slowly, she used both hands to wrap around my boobs, then gently milked me.
“Ahhhh~~~” I couldn’t hold back the moans. Both hands went to my stiff, erect penis, and I jerked off without shame.
A moment later, I produced a clone of Sekh and filled her mouth with my cock. The slime clone Niva held vanished, but she wasn’t alarmed after Tilde explained things.
When the first bottle was full, my boobs were bigger and heavier, and I orgasmed four times. Utterly devoid of breath, I was nearly at the cusp of insanity when it came time to fill the second one. Clone!Sekh was quiet, devoid of emotion, and didn’t even look up to meet my gaze, but her mouth was comfy and warm. Her tongue was a nice, hot, sultry bed to lay my cock upon, and she sucked with such enthusiasm to swallow the last bit of semen stubbornly stuck in my urethra.
But my erection never died down. Even when Sekh brought a bottle to Niva, and she drank it dry, all I could focus on was fucking the clone’s mouth. She relaxed her throat and let me take the lead. Caressing her soft cheeks, which were full of my cock, I offered my affection. My semen was like a waterfall. It drained past the corners of her mouth to her tits, where it collected in her lap. Niva licked her lips to clean them, placed a hand over her heart as if to thank me, and laid her tired head on her pillow.
The bottle Sekh held dissolved into mana and returned to me, and Tilde flew to the second bottle to stash it in our [Storage]. Clone!Sekh vanished when the real one sat down, and I wasted little time jumping towards her. We tumbled and rolled until I was on top. My fingers found hers, and we held hands while my erection rubbed her stomach. “I can’t take it... Sekh, I need you... I want to fuck you so bad...”
“Then fuck me, my liege,” she said with a cute smile. Leaning up, she kissed my lips, but I didn’t think she expected the passion I imparted.
We descended into a salacious mess to satisfy our growing desires and exhausted ourselves twice before moving to the pond, where Sekh straddled my hips while I sat with my legs in the water. She gyrated her hips with heavy salaciousness that I was drawn to her every desire. I licked her neck, cheeks, and lips with such vigor that I almost wanted to become one with her.
And I did that. I felt my slime wrap around my body like a layer of sugar, then it spread outwards and up until it enclosed Sekh. We were like two beings in one—the same body—the same passion—the same sexual lust building between our senses. My heat—her heat—our heat. It felt like her, me, and our yearning to bring out the ultimate pleasure within the other were the only things that existed in this world.
“AAAHHHHHHHH~~~~~” We erupted into a loud cry simultaneously as the slime enclosing us broke apart like a cracking egg. I shot my thick load deep within Sekh's pussy, straining with every ounce of strength to keep pulsating my hips for a second longer. The desire to remain upright abandoned me for greener pastures, and my back slammed against the cool grass.
“Ahhhhh.... Ahhhhhh... Ahhhhh...” Sekh’s hastened breaths were the only noises other than the nocturnal hoots of the owls flying near the Eagle Yew. My flaccid penis eventually slipped out of her, causing the semen to gush into the pond. But it was cleaned moments later when the water purified itself. I checked on Sekh and rubbed her back, then scratched her behind the ears before caressing her cheeks with both hands.
We remained like that—myself on the ground and her on my chest—until she had gained the strength to sit up. I took her hand in mind, and we shared another loving gaze. We dipped our post-coitus bodies in the warm water to relax our muscles. Sekh stole little pecks and licked my lips, and I’d return them with a whisper of my love.
“My liege, what do you think Irisa’s doing?” Sekh asked me, holding my erect penis by the shaft. It was like we held hands.
Kinda.
Or maybe not. But I grew my dick to its full length. If she wanted to hold it, I wasn’t going to deny her.
Besides, I was horny...very horny. Being milked must’ve awakened something within me.
“I dunno. Let’s find out,” I replied, telling the AI to search for Irisa and display the results in satellite mode. Twenty seconds later, the AI materialized and did what I asked. And there she was—a green-skinned beauty with fascinating horns sprouting off her forehead, sitting at the dinner table with her mom and dad.
“Is there a way we can communicate with them?” Honestly, I was curious about that. I thought it over for a second and realized my waypoints could form letters if I used enough. It took a minute to get my idea across to the AI, but if it produced a keyboard for me to type my message, then displayed those words in front of Irisa using my waypoints, then possibly...
Another minute later, I was typing a simple message: ‘I hope things are going fine. - Mila’ and watched in real-time as sparks of pillars appeared and suddenly shrunk to the size of a marble
“WAAA!!!” Irisa cutely yelped. She dropped her chunk of fish in her lap and hurriedly grabbed it with her hands to not let it be corrupted by the floor.
“Mila?” Kokan whispered my name. He looked up and smiled with a friendly wave.
“Wait, she can see us? Mila, dear? Are you there?” Ichiha asked.
Yes, I am. I’m sorry for scaring you, Irisa.
“That’s fine. I’m just really glad you’re okay. That blue waypoint thingie hasn’t moved in a while, so I got a bit scared.”
Oh, so it works even while in a bounded field? That’s good news. But yes, we’re doing fine. Enap’s working on the order as we speak.
We chatted for a few minutes while they ate dinner, and it was awesome that I could communicate with them like this, even though we were days away. According to them, the situation still hadn’t changed. The mines were still closed off, and it almost looked like things would arrive at a boiling point soon if Gloria didn’t fix her stubborn ways. Word of what had been going on had reached a few small villages to the north, so they were sending a few wagons of supplies, but 19,000 people were a lot. Again, it was such a boon they were a cliff / coastal city. But the dangers of overfishing would soon rear their head if this continued.
For a proper city to survive, it needed a thriving economy, and you couldn’t really have that if one of the primary components in the circle of trade—the dungeon—was cut off without a single warning. But talk of potential dangers in the future soured our conversation, so we turned it to the village. I explained about Ruru, Arguna, Aello, and even the little Dryad I’d met. I also told them I accomplished my goal of assimilating a slime and draingi and explained my evolution and acquirement of [Base Body].
It really warmed my heart to see them happy for me.
I do miss you guys.
“Aww, Mila... We miss you too. But it won’t be long, right?” Irisa said. She gave me a wink, causing my heart to skip many, many beats. “When you get back, let’s have a big dinner to celebrate!”
That sounds like fun. I’ll talk to you guys later.
Irisa and her parents looked up and waved, and Sekh and I did the same even though they couldn’t see us. When the display vanished along with the AI, I still saw Irisa’s face in my mind. Her cute smile and bubbly personality were almost infectious.
And I believed I wanted to be infected.
abdominal monster
Abominable?
“But for real. Cowfolk milk is, and I’m being serious here, way better than milk from an actual cow. It’s higher quality, has way more nutrients, and if you’re sick or recovering, a nice glass of Cowfolk tiddie juice is just what the doctor ordered. And I’m being a thousand percent serious, Master.”
Man I'd like a taste, Truly the perks of chimera being able to satisfy all your lovers fetish and needs.
Hmm yes reading with 1 hand is how the pro does it, Tftc
Abominable?
Whoops! Another typo. Sorry about that, and thanks for the correction!
Man I'd like a taste, Truly the perks of chimera being able to satisfy all your lovers fetish and needs.
Yep. A chimera can literally change any physical aspect about themselves should they have the right skill. It's the perfect existence for a lewd deviant, or someone that falls to the lewd side, such as Mila.
Hmm yes reading with 1 hand is how the pro does it, Tftc
Thanks for reading!
@RuggyRuggy
Especially considering my true nature being of an abdominal monster
I'm sure her abdomen is as monstrous as the rest of her XD
I took her hand in mind,
I'm sure that there is a joke in their somewhere, I just can't bother finding it right now...
@Jeanean
I'm sure her abdomen is as monstrous as the rest of her XD
Whoops! I thought I fixed that typo. Sorry about that. I'll correct it now.
Thanks for the chapter.
Gotta say, I was not expecting that bit of spice, tho maybe I should've... hmm.
Thanks for reading!
Chapter 47.5 is super spicy as well. It's like 5.2k words of a ton of lewds and a lot of fun between Mila and Sekh.
Am I the only one that's thinking Gloria is trying to permanently get rid of the dungeon
It's possible. She's certainly ruining the town by keeping the dungeon closed. And there's no sign of it ever reopening anytime soon. A smart ruler wouldn't want to cripple a town within their country, that's for sure. So unless she has some hidden agenda, she's just a foolish woman with a crazy amount of power.
Damn, Mila's biological AI sure did provide a better way for her to communicating with people that are close to her. A really nice feature if I do say so myself. Looking forward to seeing more uses of this feature of the AI in future chapters.
And that's not even half of it. Since she can share the waypoints to communicate with people on the other side of the world (there's no distance limit to her waypoints, one thing that makes them massively OP) Who's to say she can't use them to blind her enemies? Or make one of her enemies think they're gone crazy?
Imagine this: Mila is trying to sneak into a camp to either kill a bandit leader or rescue a prisoner or something. She can use the AI to make a 'glasses of waypoint' for the lack of a better word, and effectively blind all of the enemies. Or she can just blind one, and have everyone else think that opponent has gone crazy.
A way around this is to fight without sight. Or have eyes sharp enough to see through the waypoints.
On second thought, she can use them to form words in the sky and act as if they're from some sort of god or goddess that only a few people can see. She could probably manipulate a bunch of people that way, especially if they're very religious.
@RuggyRuggy All the ideas that you mentioned for the use of the AI on her enemies are pretty interesting.
It will be a big problem if that dungeon doesn't open, won't it??.
Thank you for the chapter ✨✨✨
A few hours later, when night fell even more across this pleasant little village, Sekh and I were cuddling in bed. She wrapped her arms around my chest and rested her head against my shoulder. Niva hugged a clone version of my slime form. Her smile was so big when she petted it, and I was happy for her. Pulling out the songleaf from [Storage], I started to play a rich, airy melody.
Cute. I wish I could see an illustration of this scene with a good angle on Niva and the slime.
How does it feel to touch the clone in slime form?
Since the slime onahole is part of Mila, would having s*x with her count as masturbation or selfcest?
Is the onahole instance as sensitive as a vagina?
“But for real. Cowfolk milk is, and I’m being serious here, way better than milk from an actual cow. It’s higher quality, has way more nutrients, and if you’re sick or recovering, a nice glass of Cowfolk tiddie juice is just what the doctor ordered. And I’m being a thousand percent serious, Master.”
Is it nutritious enough for a vampire to use Cowfolk's milk as a blood substitute?
I hope Niva can suckle straight from Mila's tiddies in the near future.
Now that I think about it, what would Niva's reaction be if Mila asked if she would be okay with sucking on her tiddies, is it faster than filling the bottle by the bottle?
Thanks for the chapter
Cute. I wish I could see an illustration of this scene with a good angle on Niva and the slime.
Speaking of images, I'm having a few problems locally generating the AI images on my computer. Until I get it fixed, images are going to be temporarily delayed for maybe a week or so. But I'm going to try my hardest to get an image of Niva and the slime. I can't promise all the details will be correct.
How does it feel to touch the clone in slime form?
Slimes are a gelatinous creature, I suppose. They're 'blubbery' and cool to the touch. Though if a slime is from a volcanic region, then they're hot/warm. But in this case, it's cool, slightly below normal room temperature.
Since the slime onahole is part of Mila, would having s*x with her count as masturbation or selfcest?
I would say selfcest, honestly. Mila's physiology does mean she's part slime. Like genetically, that is. So when she made a clone of Sekh before and had s*x with it, then she was really having s*x with herself at the same time.
Is the onahole instance as sensitive as a vagina?
They can be, but in this case, it was just a slime cylinder without any folds pressed in it. It was a new sensation, which led to Mila climaxing pretty hard. But eventually, she can make slime onaholes of Sekh's vagina, which will feel like 99.999999% like the real thing.
Is it nutritious enough for a vampire to use Cowfolk's milk as a blood substitute?
Not quite. They can get a lot of nutrients from it, but they still need blood. Not as much blood, but still need it.
I hope Niva can suckle straight from Mila's tiddies in the near future.
Something tells me that definitely is going to happen. Perhaps not right away, but it is only a logical expectation as their relationship deepens.
Now that I think about it, what would Niva's reaction be if Mila asked if she would be okay with sucking on her tiddies, is it faster than filling the bottle by the bottle?
Possibly alarmed/shocked at first, and she might need to be convinced that it's truly alright for her to do so.
And yes, it is faster than filling the bottle because of the stimulation.
@RuggyRuggy
Speaking of images, I'm having a few problems locally generating the AI images on my computer. Until I get it fixed, images are going to be temporarily delayed for maybe a week or so. But I'm going to try my hardest to get an image of Niva and the slime. I can't promise all the details will be correct.
No problem and thanks for her dedication.
Slimes are a gelatinous creature, I suppose. They're 'blubbery' and cool to the touch. Though if a slime is from a volcanic region, then they're hot/warm. But in this case, it's cool, slightly below normal room temperature.
When you said 'Blubbery' did you mean literally similar to fat? That's what I found when I tried to translate the word and search.
Not quite. They can get a lot of nutrients from it, but they still need blood. Not as much blood, but still need it.
So, for vampires Cowlfolk's milk could be used as a supplement to reduce the need for blood, but not zero it, right?
I've read stories with vampires using breast milk as a substitute for blood, and from what I've researched the composition of milk is very similar to blood with the main differences being the absence of blood cells and the presence of lactose. And if I remember correctly 4 liters of blood pass through the mammary glands of a cow to produce 1 liter of milk.
Possibly alarmed/shocked at first, and she might need to be convinced that it's truly alright for her to do so.
Once convinced, how would Niva react to being sat on Mila's lap to be breastfed while being hugged and headpatted like a baby?
Now that I stop to think about it, does Niva also have a mother complex?
Can cowfolks lactate without ever becoming pregnant?
From what I can see, does a Cowfolk's breast sensitivity increase during lactation, or is lactation itself pleasurable for them?
With the current sensitivity of her tiddies, could Mila come even if Niva just suckled seriously like a baby?
@Gin_Otamegane
When you said 'Blubbery' did you mean literally similar to fat? That's what I found when I tried to translate the word and search.
Perhaps that was the wrong word. Think of the slime as feeling like thick jello. Don't know why I used the word blubbery, but think of thick jello, and it's like that. If you press or push on a slime's body, it'll bounce back with a nice jiggle.
So, for vampires Cowlfolk's milk could be used as a supplement to reduce the need for blood, but not zero it, right?
Yes. A vampire would need less blood if they regularly drank Cowfolk milk.
Once convinced, how would Niva react to being sat on Mila's lap to be breastfed while being hugged and headpatted like a baby?
Oh, she would love that a lot. Like a lot a lot.
Now that I stop to think about it, does Niva also have a mother complex?
She has a slight one. I can't get into any spoilers about her mother/family since her family and her expanded past is talked about in chapter 51.
But yes, you could say she has one.
Can cowfolks lactate without ever becoming pregnant?
Yes, they can.
From what I can see, does a Cowfolk's breast sensitivity increase during lactation, or is lactation itself pleasurable for them?
It's both.
With the current sensitivity of her tiddies, could Mila come even if Niva just suckled seriously like a baby?
Definitely. Without a doubt. And she'll be a quick shot.
@RuggyRuggy
Perhaps that was the wrong word. Think of the slime as feeling like thick jello. Don't know why I used the word blubbery, but think of thick jello, and it's like that. If you press or push on a slime's body, it'll bounce back with a nice jiggle.
I see. Looks like it would make a nice hugging pillow.
Making a clone for Niva to hug was also part of Mila's training to level the skill?
Yes. A vampire would need less blood if they regularly drank Cowfolk milk.
To what extent could the need for blood be reduced?
Now that I come to think of it, how often do the vampires in your world need blood normally?
Oh, she would love that a lot. Like a lot a lot.
If Niva would love it so much, the scene would be even better to watch.
If Niva was fully healed, could she come just from being breastfed, pampered, feeling the affection/love and noticing Mila's reactions to the pleasure of having her tiddies suckled by her?
Yes, they can.
At what age do Cowfolk girls usually start lactating?
What normally triggers a Cowfolk girl's lactation for the first time?
It's both.
If so, Cowfolk mothers must often cum when they breastfeed their babies, right? Or would they need to be very excited to get to that point?
Definitely. Without a doubt. And she'll be a quick shot.
Would Mila be a quick shot due to not being used to the pleasure of Cowfolk tiddies or because Cowfolk tiddies during lactation are even more sensitive than her pp?
@Gin_Otamegane
Making a clone for Niva to hug was also part of Mila's training to level the skill?
Yes. Creating clones will be vital to Mila's success in the future since it opens up a whole bunch of new tactics for her, so she wanted to get a start on training the skill as soon as possible
To what extent could the need for blood be reduced?
Now that I come to think of it, how often do the vampires in your world need blood normally?
Okay, a regular, healthy vampire needs to drink blood 3x a week. About a liter each time, so 3 liters per week. A wounded or injured or sick vampire would need more blood than that.
A healthy vampire drinking a glass of cowfolk milk would just need blood once a week, at 1 liter per week.
And if a vampire is especially active or doing a lot of fighting, then the blood they need increases as well.
But 3x a week without any cowfolk milk to provide nutrients is about the average. For vampire colonies and towns, they usually have a blood farm where they extract blood from their slaves/prisoners/enemies.
If Niva would love it so much, the scene would be even better to watch.
If Niva was fully healed, could she come just from being breastfed, pampered, feeling the affection/love and noticing Mila's reactions to the pleasure of having her tiddies suckled by her?
Yep. Should she be healthy/fully/mostly healed, then a combination of the milk, Mila's reactions, and Niva's own affection for Mila would be enough for her to climax.
At what age do Cowfolk girls usually start lactating?
What normally triggers a Cowfolk girl's lactation for the first time?
Cowfolk are late bloomers, so they don't start lactating until they reach puberty, which happens, usually, when they're around 16-ish years old. It lasts about 2-3 years.
What triggers it? A feeling of strong love or affection for someone. In the Cowfolk community, lactating for the first time means you've fallen in love, and when you get these strong feelings, they will usually lactate, but some Cowfolk can purposely trigger their lactation. Mila can do it, but it's more like a weird cheat/workaround because she's a chimera.
If so, Cowfolk mothers must often cum when they breastfeed their babies, right? Or would they need to be very excited to get to that point?
Their motherly instinct takes over their sexual feelings/excitement and numbs it so they can feed their child in peace. It isn't rare for that to happen, but it also isn't super common.
Would Mila be a quick shot due to not being used to the pleasure of Cowfolk tiddies or because Cowfolk tiddies during lactation are even more sensitive than her pp?
It's a little bit of both. Lactating is a brand new feeling for her, much like discovering s*x for the first time when she made love with Sekh after moving in with Irisa and her mother. But their nipples are also way more sensitive when they do lactate, and the only time they aren't that sensitive is when they're breastfeeding their child.
@RuggyRuggy
Yes. Creating clones will be vital to Mila's success in the future since it opens up a whole bunch of new tactics for her, so she wanted to get a start on training the skill as soon as possible
Yes, many new tactics for both the battlefield and the bed.
But 3x a week without any cowfolk milk to provide nutrients is about the average. For vampire colonies and towns, they usually have a blood farm where they extract blood from their slaves/prisoners/enemies.
Is there no one who earns a living by selling his own blood of his own free will?
Yep. Should she be healthy/fully/mostly healed, then a combination of the milk, Mila's reactions, and Niva's own affection for Mila would be enough for her to climax.
What would Mila, Sekh and Tilde's reactions be to seeing Niva cum because of this, without having any of her sensitive parts touched?
What triggers it? A feeling of strong love or affection for someone. In the Cowfolk community, lactating for the first time means you've fallen in love, and when you get these strong feelings, they will usually lactate, but some Cowfolk can purposely trigger their lactation. Mila can do it, but it's more like a weird cheat/workaround because she's a chimera.
If so, why did Mila only start lactating when she was lovemaking with Tilde using the mini-clone and not before with Sekh?
Their motherly instinct takes over their sexual feelings/excitement and numbs it so they can feed their child in peace. It isn't rare for that to happen, but it also isn't super common.
If so, it must be pretty hard for Cowlfoks without babies to milk themselves to sell their milk, without getting exhausted from cumming during the milking, right?
@Gin_Otamegane
Is there no one who earns a living by selling his own blood of his own free will?
There are, but they're not common.
What would Mila, Sekh and Tilde's reactions be to seeing Niva cum because of this, without having any of her sensitive parts touched?
They'd probably think it was cute.
If so, why did Mila only start lactating when she was lovemaking with Tilde using the mini-clone and not before with Sekh?
That is a slight spoiler(?) I think, but probably not, but the answer lies within the AI. The AI can take control of a clone, and what the clone feels the AI can feel. It's how the AI can learn more about emotions and touching and all that. But in this case, the AI didn't have full control over the clone. It just implanted it's consciousness in it, and since the AI came from Tilde, the conduit of the TDL Training System, the love the AI has for Tilde unconsciously triggered a Cowfolk's lactation.
But now that the clone has lactated, when it returned to Mila, Mila received everything it did, including the inherent know-how to lactate on command, and also when she's feeling really horny or in a really loving mood.
If so, it must be pretty hard for Cowlfoks without babies to milk themselves to sell their milk, without getting exhausted from cumming during the milking, right?
Yep. It's a little bit of a challenge for them.
