The Larvae Grow
The larvae, which had grown rapidly by alternating between feeding on breast milk and sleeping peacefully, had now reached a size slightly smaller than a hand—just like when they first encountered the parasitic tentacle tails. Ruya looked at the larvae curled up and tangled together on the bed and asked,
“Are they fully grown now?”
“Yes, when I first met my tentacle tail, it was about this size too.”
“Then it’s about time they found hosts. Starting with me.”
“Go ahead and pick whichever one you like.”
Ruya tilted her head while watching the larvae bob their round heads, pondering which one to choose. In the end, she selected the one with the brightest body color among the four and lifted it up.
“I’ll take this one. I like the color.”
“It is quite unique because it’s so pale.”
Unlike my own tentacle tail—which had been such a deep purple that it could be mistaken for black at first glance—the larvae each had distinctly different shades. They were all in the purple spectrum, but the intensity varied so much that they were easily distinguishable at a glance. The one Ruya had chosen was especially light, possessing a soft lavender-colored body.
“What do I do now? Do I just press it against my butt?”
“I’m not entirely sure. Even I didn’t see how it entered my anus the first time, so I don’t know the exact process. For now, take off your clothes and lie face down.”
Ruya quickly stripped naked and lay prone on the bed. I spread her buttocks apart to expose her anus and commented,
“Such a clean anus. Not a single hair either.”
“Hey~ Don’t look so closely.”
“Once the tentacle tail settles in, you won’t have many chances to see it again anyway. Let’s see here…”
When I spread her anus with my fingers, it opened surprisingly easily without much resistance. Consciously relaxing the anal sphincter like this was a skill not easily learned without experience in anal intercourse.
“It seems you’ve enjoyed quite a bit of anal sex while I wasn’t looking. With Gwangnam oppa, I assume?”
“Who else would it be? He kept begging to do it in the back, so just remembering how I had to stretch my anus makes me sigh~”
“Hehe, but it must have felt good, right?”
“Well, it did feel good. The sensation was nice. Though I did suffer a bit because of how stretched it became.”
“That makes sense.”
Since she had to accommodate Gwangnam oppa’s rather massive member, the expansion must have been considerable. No matter how strong the sphincter’s contraction power, repeated stretching and anal sex would eventually weaken it, making it unable to tighten properly. In the worst case, it could lead to leakage. I had seen many angels whose anuses were ruined by anal sex; if left untreated, they couldn’t contain feces, so many of them wore anal plugs even in daily life.
“Still, thanks to Master, I’ve been rejuvenated and my anus is back to normal.”
“It’ll be plugged up again soon enough. But becoming a host means you won’t be able to have anal sex with Gwangnam oppa anymore. Is that okay?”
“Madam convinced Gwangnam that anal sex isn’t good for his concubines’ health, so we’ve decided to limit it to only very occasionally with Madam from now on.”
“Using the concubines’ health as an excuse somehow feels like a pretext to me.”
“Honestly, I think so too. It felt like Madam wanted to monopolize anal sex.”
I didn’t know the reason, but it seemed Madam had no intention of letting the concubines service anal sex. Maybe she thought Gwangnam oppa particularly enjoyed it and wanted it all to herself? While pondering why Madam had taken such measures, I continued caressing Ruya’s anus to loosen it even more gently. I scooped up the thick, sticky love juices flowing from her moist pussy, coated my fingers, and stirred them inside her anus as I spoke.
“I didn’t even do much foreplay, yet your panties were already soaked. At this rate, I’m not sure if you shouldn’t be wearing a diaper.”
“Hey~ Stop teasing and just do it already.”
“Alright.”
At Ruya’s urging, as she wiggled her hips impatiently, I grabbed the pale lavender larva and pressed its head against her anus. The moment the round head touched her hole, the previously docile creature began to wriggle and forcefully push its head inside.
“Ahng!”
“Try to relax more.”
“I’m relaxing as much as I can. It’s not going in easily because it’s shrunk back down.”
Ruya kept fluttering her anus, trying to widen the opening, while I helped by spreading her cheeks wide. After a long struggle, the larva finally succeeded in shoving its head inside with a wet pop.
“Aahng~”
“It’s in. Now we just have to wait.”
“Ugh… It feels so unfamiliar because it’s back to its pre-stretched state.”
With only the tip of the tail remaining outside, the larva’s body fully inserted into her anus, it became docile again as if its earlier vigor had never existed. Ruya, who seemed to find the sensation very strange, touched her buttocks and sat up, then looked at the remaining three larvae.
“What are you going to do with the others? It doesn’t seem like we can just release them into the wild.”
“Hmm… I was thinking of asking the women I know around here first.”
“That would probably be best. Ugh, I need to lie down for a bit. My butt feels uncomfortable.”
Unlike me, Ruya had a normal body, so having the larva inside seemed quite uncomfortable for her. After leaving Ruya in the room, I was walking to find women who might become hosts when Elsa spoke to me.
'Leave one as a sample for me.'
“What are you going to do with it?”
'I want to run various experiments. Drug tests, dissection, that sort of thing.'
“Ugh, thinking about using one of the children I gave birth to as a test subject gives me such strong aversion. Is this because of the maternal instinct granted to me?”
The moment I considered using the larva for experiments, an overwhelming sense of rejection washed over me. It seemed to be due to the maternal love imposed by the mother system.
'Well… based on the information we have so far, it appears to be a symbiotic organism that’s harmless to the host, so there isn’t much need for further research. If the aversion is that strong, I’ll drop it.'
“Yeah, you should. It’s making me nauseous.”
The aversion vanished the instant she agreed to cancel the experiment, confirming that it was indeed caused by artificially amplified maternal love.
'I don’t have any particular complaints, but is it really necessary to forcibly inject maternal love like this?'
'It’s a necessary measure. Maternal love is also an emotion generated by hormonal reactions, and since you’re a full-body prosthesis, sister, it doesn’t occur naturally for you.'
“Is that so… I see.”
'Anyway, now that your womb is empty, we can begin bioroid production. Since I’ll be raising my sibling’s AI, please keep it empty for a while longer.'
“Understood.”
While walking and listening to Elsa’s request, I ran into one of the maids. Since it was a maid I interacted with frequently, I thought she might have less resistance to symbiosis and approached her.
“Excuse me.”
“Yes, Lady Elisha.”
The maid answered with a graceful smile. I explained about the parasitic tentacle tail larvae and tried to persuade her to become a host.
“Oh my, you want to give me one of your tails, Lady Elisha…?”
“What do you think? Would you be willing to become a host?”
“To be allowed to receive Lady Elisha’s symbol into my body—it would be an honor. Please take good care of me.”
“Ah, yes.”
Contrary to my expectations, the maid gladly accepted, even seeming delighted. But when had the tentacle tail become my symbol? This was more bewildering to me.
“Ah, by any chance, are there two more maids willing to become hosts? There are three larvae in total.”
“Please wait a moment.”
The maid turned her head, touched the communicator attached to her hair ornament, and spoke.
Thanks to my auditory sensors faintly picking up the communication, I could hear both the chief maid and the other maids’ responses. The maid who had put down the communicator bowed her head politely and said,
“If you wait a moment, I will select candidates and inform you.”
“Yes… Thank you.”
I was taken aback by how enthusiastically even the chief maid reacted. I had no idea why the tentacle tail was causing such a commotion, but it seemed there would be no problem finding hosts, which put my mind at ease.
That night, the chief maid, the maid I had spoken with earlier, and one other maid came to me, bowing their heads respectfully.
“Lady Elisha, we have selected three candidates.”
“Hmm… Three candidates, so the chief maid is also…?”
“Yes. We fairly selected them after considering various factors such as loyalty and devotion to the Eden royal family.”
“I see… Thank you for accepting my request.”
“It is our greater honor.”
Seeing them bow again while saying it was an honor, I signaled them. One by one, they entered the room. I carefully took the sleeping larvae out of the basket and gently placed them on the bed. The larvae, suddenly moved to the bed, woke up and wriggled, but calmed down when I stroked their heads.
Ruya, who had been watching from where she lay on her side on the bed, asked,
“Should I leave the room?”
“It might be embarrassing to show such a sight to others, so fewer eyes would be better.”
At my answer, she stood up and said,
“Ugh, my anus feels so full that it’s uncomfortable to move.”
“It’s because the settlement isn’t complete yet. Once it’s done, the discomfort should mostly disappear.”
“Yeah. Anyway, I’ll step out.”
Ruya left the room with an awkward, waddling gait. A short while later, I called for them to enter, and the chief maid opened the door and came in.
The chief maid was an ultra-elite who had graduated at the top of Eden’s maid training program. A woman of outstanding beauty, she had earned Maria’s trust and was now in charge of managing the entire Eden royal household. Her reddish-gold hair was neatly tied up, and she wore a spotless maid uniform with a gold-embroidered belt denoting her position as chief maid. Though her breasts were not particularly large, her naturally excellent bone structure made her uniform look stunning. Simply standing there in her maid attire, she was a beautiful sight.
She gave a slight bow and said,
“Please take good care of me.”
“I should be the one saying that. Now, please lift your skirt and lie face down on the bed.”
“Yes.”
Without hesitation, she skillfully gathered the long skirt of her ankle-length maid uniform, exposing her lower body, and lay down on the bed. Her buttocks were rather slim due to low body fat, but her wide pelvis—thanks to her good skeletal frame—made them quite attractive.
“I’ll lower your underwear. And please relax your buttocks as much as possible.”
“Understood.”
When I pulled down her immaculate underwear, I saw a neatly groomed pussy and a perfectly round anus. It seemed she had washed and prepared beforehand; even her anus gave off a pleasant fragrance. I spread it wide open and said,
“The sensation of it entering will feel strange, but if you endure it and stay relaxed, it will be over quickly.”
“I understand.”
“I’ll begin now.”
I pressed the head of the larva—which was such a deep purple it could almost be mistaken for black—against her anus. Just like with Ruya, it immediately began moving on its own, trying to burrow inside. A startled moan escaped the chief maid.
“Kyaaht!”
“It’s going well, so stay calm. And relax your muscles.”
However, perhaps because she had no experience, she couldn’t relax easily. The larva also seemed confused by the strong force pushing it out and was hesitating. Left with no choice, I gathered essence in my hands and massaged her lower belly and buttocks to ease her tension.
“There, relax. That’s it. Doesn’t it feel good? Just surrender your body to it.”
“Hngh…”
Her body relaxed under the pleasure brought by the essence, and the tension in her anus began to loosen. Sensing that the force pushing it out had weakened, the larva once again vigorously pushed its head inside. After helping it enter by loosening her body with essence, it didn’t take long before the symbiosis was safely completed.
“Hoo… Thank you for your help.”
“Not at all. You’re becoming a host, so of course I should help. It may feel a bit uncomfortable for a few days while the tail settles in. It’s a smart one, so it should avoid danger on its own, but please be careful not to let it touch hot water.”
“Yes, Lady Elisha.”
With a flushed face and twitching buttocks, the chief maid listened to my explanation before leaving the room. The next maid then entered. In this way, the larvae that had safely found hosts and been distributed grew remarkably fast.
They grew even faster than I had. In just a few days, they had grown large enough to reach just above the thighs and were moving about actively.
“Their growth is unusually fast.”
“Isn’t this normal?”
“No, it took me quite a long time. I only grew quickly after I started consuming semen in earnest. But these children grew this much in just a few days.”
I said this while examining the tail on Ruya, who was lying face down on the bed and pushing her buttocks toward me. When I spread her cheeks apart, I could see that the tail’s body had already fused with her anus and become connected. I touched the seamless junction where the hole had been completely sealed and said,
“It seems their original food is indeed the host’s… that. Since I don’t defecate, I could only consume semen, which slowed my growth.”
“Ugh, it tickles.”
“Since the anus and tail are almost fully fused now, it should grow even faster soon. Lie on your back.”
“Mmm.”
Following my instructions, Ruya lay flat on the bed. I placed my hand on her abdomen and injected essence to examine her condition. Through the essence that spread out like waves, I could sense the energy of the tentacle tail that had filled most of her large intestine. From the way it had fused only up to the end of the large intestine—just before the small intestine—it seemed this species normally settled by attaching only to the large intestine, unlike T-12, which had entered all the way to the small intestine and fused there. It made me realize just how much my own tentacle tail must have struggled when it settled in my body, which lacked a proper large intestine and only had similarly shaped bio-parts. No wonder it had been so desperate for semen; it had been trying to make up for the lack of normal nutrition.
“It’s settling in smoothly.”
“I could control my urine at will, so that was convenient, but I couldn’t do anything about the big one. Ever since this one came in, I haven’t had to go for the big one at all, so it’s much more comfortable.”
“That’s one of the advantages of anal-symbiotic organisms.”
After the simple examination, Ruya got up, put on her clothes, and brought up a different topic.
