Uterine Intrusion
I was practicing my singing in time with the music flowing from the state-of-the-art speakers I had painstakingly manifested, when the door burst open with a loud bang and Kyubey barged in.
"Elisha!"
"What is it?"
"You need some way to see outside, don't you? Uriel's fighting monsters right now."
"Ah, just a moment."
Kyubey grabbed my hand and pulled me into her room. The TV there had grown much larger, covering the entire wall, and the speakers delivered the vivid sounds of battle.
"Let's sit here and watch."
"Who are those men?"
Around Kyubey, lounging on the luxurious wide sofa, stood men in odd outfits, each holding some object and waiting attentively. One of them approached me, guided me to the sofa, and helped me sit.
"They're butlers I made in my spare time. Handsome, right?"
"They look like celebrities I've seen on TV. But do you really need butlers here?"
"Doesn't it feel good to be waited on by handsome men? I've made sure their cocks are nice and thick to my taste. Want to try one?"
Kyubey said this while fondling the crotch of the rabbit-eared man standing beside her with a tray of drinks. As always, her sexual appetite seemed endless.
"I'll just watch, thanks."
"Oh my, watching while having sex would be even better. Fine, at least get a massage then."
She snapped her fingers at the man beside me, and he knelt at my feet. He pulled a bottle from his pocket, poured massage oil onto my legs, and began rubbing it in.
Handsome men weren't my type, but having a well-built guy sitting at my feet and massaging my legs felt surprisingly pleasant.
My attention had drifted to him when a thunderous monster roar pulled my gaze back to the screen. A reptilian monster resembling a crocodile, its massive body showcasing enormous power, came charging forward.
The hyper-realistic sight of earth ripping apart and small plants shattering drew an admiring gasp from me.
"Wow~ That's impressive."
"Should I record it and upload it online?"
"No. God's appearance would be in it. Eep."
The man's hands, which had stayed at my feet, traveled up my calves. His gentle rubbing at just the right pressure felt faintly sensual.
I deliberately turned my focus back to the screen to watch the fight.
Unlike Kyubey, who had no talent for combat, Uriel was holding her own quite well. Her bold swings with the folding battle axe as she smashed monsters were especially striking.
The screen continued to fill with the screams and bloodshed of monsters being hacked, crushed, and severed by the axe for some time.
"Hngh."
"Hehe, feels good, doesn't it?"
The hands that had moved from my calves to my thighs grew steadily bolder. Every time his fingertips brushed near my pussy while rubbing my inner thighs, pleasure bloomed and stoked the heat inside me.
I hadn't thought much of it at first, but once my body began to feel the pleasure, it heated up quickly and the desire to stop vanished.
"As expected, Elisha is so weak to pleasure, you know~ Let's enjoy this together."
"Hah!"
Kyubey leaned close and kissed me. I knew she was a separate being, yet having someone with the exact same face as mine pressing her lips to me felt strangely disorienting.
Her tongue invaded my mouth and skillfully ravaged every inch. She'd surely had experiences similar to mine, yet she was far too good at it.
"Mmph, haa."
"Haa, what a cute face. I love seeing you flushed with pleasure. You're not acting, are you?"
"Mm, about half and half?"
"Don't act. Just feel the pleasure exactly as it comes. Good girl."
When I stopped performing and let my body react naturally, the eyes that met mine were those of a predator eyeing its prey.
Kyubey's caresses combined with the men's massages made my body burn hotter and hotter. Yet they avoided every truly sensitive spot, leaving only growing frustration.
"Haa, now…"
"Hmm~ If you want something, you have to say it clearly, don't you?"
"Ugh."
The way Kyubey's fingers only circled my nipples and the hands only massaged around my pussy made their teasing intent obvious.
For some reason I didn't want to give in to her, so I kept holding out. After enduring for so long, I reached the very brink of climax.
"Ah, I'm going to…"
"Hmm. Stop."
At Kyubey's command, the men massaging my body froze, then seized my wrists and ankles, pinning me down.
I thrashed at the agony of being halted right before release, but my pleasure-drained body couldn't break free from her hold.
"Hngh, why are you doing this?"
"Because tormenting you is so much fun, Elisha."
Looking down at me, Kyubey licked her lips, her eyes gleaming with dangerous hunger. She wagged her tail in front of my face—pulled out at some point without me noticing—and said,
"Now, tell me quickly. Where and how do you want me to make you cum~"
"Hii!"
The soft, plush touch of her tail alternated between my labia and clitoris, tickling them. The gentle movements seemed to guide me exactly where to speak, and my mouth opened on its own.
"P-please make me cum with my pussy."
I reflexively closed my eyes so I couldn't see her, but the sound of laughter told me she was smiling.
"Hehe, Elisha really is adorable. Uriel is too obedient, so she lacks that cute charm. What a shame."
"You did it with Uriel too? Hngh."
"I'm the one who taught that girl her sex techniques."
"Whoa, that's unexpected."
I had assumed Uriel, born with the memories and knowledge of archangels, would be naturally skilled, but it turned out Kyubey had taught her.
At that moment, Kyubey's tail thrust deep inside me in a single stroke.
"Ungh! How can you put it in while I'm still talking!"
"Yes, that feisty reaction is exactly what makes it good~ Oh, did you know this?"
The tail that had been spiraling inside me to stimulate every wall suddenly stopped and remained perfectly still.
"What the…"
"A succubus's tail can invade a female's uterus. Like this."
The tail, which had maintained a decent thickness, thinned to the width of a needle and began piercing through my cervix into the womb.
The sensation of a foreign object invading my uterus made me struggle, but I was held so tightly that even my full strength couldn't move me an inch.
"Hik, what are you suddenly doing?"
"Just stay still~ Uriel liked this too."
The tail entered my womb with surprising ease. Even without looking, I could feel it split into two branches and begin groping around inside.
The unknown sensation of my womb being touched sent shivers across my skin, yet I also felt the organ itself growing hotter.
"It should be around here~ Ah, found it."
"Haa, haa."
The tail that had been exploring my womb dug into a narrow passage. The pleasure surging through that tight channel pushed me over the edge.
"Haaang!"
The climax that bleached my vision white made my body convulse uncontrollably. Ah, direct internal stimulation of the womb was overwhelmingly intense.
As the waves of pleasure slowly receded, I caught my ragged breath and opened my eyes to see Kyubey's triumphant face.
Irritation flared, and I snapped,
"No matter if you're my sister, isn't this too much? Take it out now."
"Oh my, you looked like you were enjoying it. Fine. I finished the procedure while you were climaxing anyway~"
"What procedure… ngh."
Even as the tail withdrew from my womb, it left powerful stimulation all the way out. Kyubey rubbed my lower belly as she explained.
"A succubus's tail is an organ for special modifications that raise a female's vital energy. It's less obvious than a yin brand, but more efficient for this purpose. It enters the uterus, locates the ovaries, and injects a special secretion."
"What is that? When and where did you learn about it? More importantly, this is a mental space—can that even work here?"
Kyubey climbed off me, sat down, and snapped her fingers. The men restraining my body immediately withdrew in perfect order.
As I sat up, Kyubey continued.
"Well, it worked, didn't it? No matter how much of a mental specialist I am as a succubus, this space is an unknown domain, so there's a lot I don't understand. Anyway, the ovaries injected with the secretion develop a powerful breeding urge. They begin producing substances that send the body into heat to encourage mating with males."
"Sigh. When I see things like this, I sometimes suspect succubi really are monsters."
"Call us a species, please. And the ovarian modification will be complete in three days."
Both QA and Kyubey had a tendency to act first and think later. Was it a racial trait of succubi? It was fortunate this was only happening inside the mental space; it would have been troublesome if it affected my real body.
"Wait, you said you did it to Uriel too, right?"
"Yes, the modification finished after three days. You wouldn't know, Elisha, but seeing Uriel flushed and restless from sexual frustration was incredibly cute~ Hehehe."
"So that's why she enjoys sex with God so much?"
I had wondered why the seemingly conservative Uriel was so eager for sex. It turned out Kyubey was the reason. But she had done the same thing to me?
"Can't this be reversed? It's a pretty dangerous ability, isn't it?"
"Ehh~ I want to see you overwhelmed by frustration and not knowing what to do. If you really want, try handling it yourself~"
"That's not fair!"
"Ah!"
The moment I protested to the mischievous Kyubey, the mental space shook violently. After the heavy tremor subsided and I tried to understand what had happened, Kyubey's shout rang out.
"Look over there!"
When I turned to the screen she pointed at, I saw a figure surrounded by countless monsters. The slightly blurry image suggested the earlier impact had come from a blow to the head that rattled the brain.
"I thought she was fighting well, but her lack of real combat experience is clearly a major issue. She's not used to wielding a battle axe, either."
With monsters rushing in from every direction, Uriel's panic from her lack of practical experience could be felt even here. Still, her body was incredibly sturdy; even after taking a hit to the head, her brain had only shaken slightly and she remained functional. If she hadn't been a full-body prosthesis, her skull might have burst.
"Looks like you should head out there."
"I'd like to, but I only have experience in hand-to-hand combat…"
"That god fellow over there is killing them with his bare hands, though?"
Indeed, in one corner of the view, the god was slaughtering monsters with his bare hands. Whether struck or hit, he paid it no mind and focused solely on killing. Without dodging or blocking, he simply chained attacks together, making his killing speed noticeably faster. Was that why he preferred fighting while taking hits?
"Wow, he's as hot-blooded in battle as he is in bed."
"Ah, he must have gotten annoyed. He's picked up a travel bag and started using it."
With an expression of clear irritation, he stopped killing them one by one, grabbed the heavy metal travel bag, and began swinging it wildly. Each swing sent monsters exploding or flying through the air in ever-increasing numbers. The hesitant creatures faltered, giving Uriel breathing room to regain her composure.
Now more cautious after the blow to her head, Uriel's precise axe work combined with the god's storm-like bludgeoning quickly finished off the reptile-type monsters.
"It's over."
"They're moving on immediately."
As soon as the monsters were dealt with, the pair started running again without rest. Our bodies were full prostheses, but how could the other archangels maintain this pace? The well-trained physique I had noticed before was clearly a necessity.
"Now that it's safe, shall we continue?"
"No thanks. The mood is gone."
Kyubey looked disappointed but withdrew with a mysterious smile.
Our journey continued for two more days. During that time we encountered a wide variety of monsters—giant fish-like creatures that lived on land, bipedal turtle-like monsters, and more. They were all slaughtered the moment we met them, but seeing such strange creatures up close was genuinely entertaining.
After two days of real combat, Uriel had grown skilled with her axe. She swung it powerfully, bisecting the torso of a plant-type monster blocking the path.
Watching her, the god said,
"You've become quite proficient with the axe, Uriel."
"Thank you."
"These past few days only you have come out. Don't the other personalities appear?"
The question was so abrupt that for a moment I couldn't process it. Huh? What? He knew about the other personalities?
What? When did he find out?
Now that I think about it, it would be strange if he hadn't noticed. But does he usually ask so suddenly?
"For smoother service, I asked the others for their understanding."
You told him!
Why would you say that?
"Previously, when Kyubey was having sex with God and we got caught, I told him then."
Ehehe. Did I enjoy it too much?
In the end it was Kyubey's fault again.
I had thought he'd simply noticed on his own, but it turned out Uriel had told him everything. I hoped she hadn't revealed our plans as well.
"He noticed, so I revealed it. I judged it necessary anyway."
Did you tell him our plans too?
"Not that. Not yet."
Ugh.
"Are you conversing with each other right now? The ability for personalities to communicate is quite fascinating."
His eyes, which usually showed almost no emotion, now held clear interest. Yes, our situation was indeed very interesting—especially to scientists.
Argh! Since it's come to this, why don't we just reveal everything?
What do you mean?
Our purpose. He seems more reasonable than we expected, doesn't he?
But wouldn't it be better to follow the original plan?
The original plan of winning first and then making him listen was meant to create an attitude where he would hear us out. It's essentially the same.
"I agree with that."
Even Uriel, who was carving a path by chopping down the lush vegetation with her axe, expressed agreement.
Still, I wondered whether the self-willed god would be persuaded by mere words. Unlike my worries, both Kyubey and Uriel seemed to trust him deeply.
That man does as he pleases, but if something neither helps nor hinders what he wants, he doesn't pay it any attention.
"God will actually be pleased."
That makes sense coming from you, Uriel, but when did Kyubey start evaluating him so favorably?
I felt it clearly when we had intense fun before. A cock doesn't lie.
The standard of judgment seemed questionable, but since it came from a succubus, it somehow sounded almost convincing.
