I Went About My Life Normally Without Noticing It Was a World With Few Men, and Things Went Terribly Wrong - 18

Chapter 18: The Beginning of a New Daily Life

ーーーーーーーーーーーーーーーーーーーー

It had been about a week since I returned from the hospital. I had been cooped up in my house since then. The very first thing I did upon returning was clean the house. Not only did I retrieve the kitchen knife from under the bed, but I also wanted to keep the room clean if Yuka-san or Celly were going to be visiting from now on.

Yuka-san, who had the knife returned to her, was deeply apologetic and thanked me again. I had thought she was a pushover for falling for someone like me, but perhaps it wasn’t just that. After all, think about it. Setting aside the reverse rape, to readily forgive someone who broke in to commit a robbery and then continue to speak with them normally afterward wasn’t just being “generous.” It would only be natural for her to have a lifelong debt of gratitude to me because I had left her scot-free after all that.  Yuka-san seemed to view me almost like a saint. 

Well, I’m not actually a man with such a broad heart…

For the most part, I was just after her body, but that kind of idea probably didn’t even exist in this world. Now then. These days, university exams for most subjects had changed to a format where they could be taken while staying at home. Reports, of course, could be submitted via email or through the academic information system. My exams finished today, but since there were still various reports to do, I hadn’t become idle. Right now, I was in the middle of reading a book in bed.

My only opportunities to go outside were for nighttime trips to the convenience store. However, the one thing that had changed from before was that Yuka-san now accompanies me.

Whether it was thanks to her presence, or whether there were actually few dangerous people like her, either way, this past week had consisted of peaceful days where I hadn’t been attacked like that first time I went out. 

Should I breathe a sigh of relief that it’s over, or should I feel lonely because of it? 

…To be honest, there was a part of me that couldn’t deny the latter feeling was quite strong. Initially, I had been apprehensive, thinking I didn’t want to be attacked by an ugly older woman. But thanks to my conversation with Yoshino-sensei, I realized there was almost no risk of that.

First was the content of what she told me regarding her daughter Celestine’s(Celly’s) circumstances in this country. I realized that this country had seen an influx of foreign blood for about a hundred years, and thanks to that, appearances were overall diverse and the average level of beauty was high. In addition, the intense libido that caused one to become agitated during heat and resort to reverse rape was limited to young women. Specifically, it was said to be from puberty to the mid-twenties.

And one more thing. When Sensei was choosing subjects for the experiment, she mentioned that she herself had long since gone through menopause. I looked up her career after returning home. She was still forty-five. Feeling a sense of incongruity, I looked into it and found that for women in this world, menopause was usually complete by the late thirties. This, too, must be a result of evolution. It was nothing but a waste of resources to bleed every month and feel unwell even at an age when one could no longer bear children.

Taking all the above together, the possibility of me being attacked was basically limited to lovely women twenty-five years old or younger. At most, it wouldn’t exceed the mid-thirties. Once I realized that, I had nothing left to fear. I felt like saying, “Go ahead and attack me as much as you want!” but since it was not my intention to worry Yuka-san or Celly unnecessarily, I was currently restraining myself for the time being.

As for those girls… Celly only came over to visit once. Of course, when it came to things to do at home, there was only one thing we would be doing. The reason she only came once was likely because she was busy with the exam period. She was a medical student, after all. I wanted to believe it was not because she disliked me…

Since Yuka-san was originally a resident of the room next door, she spent all her time in this room every day. We basically had been living together since then. In fact, she had already brought over various personal belongings from her own room, and right now she was in the middle of taking a bath here… No. It seemed she had finished bathing and was drying her hair instead. 

Surely she isn’t marking her territory by spreading her scent, is she? Is that why it’s been difficult for Celly to come over?

“Meow.” 

“Whoops. What’s up?”

Speak of the devil. It seemed she had finished drying her hair, and she slumped down on top of me as I lay facedown reading a book. That sensation… It seemed she wasn’t wearing a bra under her pajamas. She was deliberately pressing her breasts against my back to appeal for something.

No, I won’t say “something.” She’s definitely trying to coax me to have sex with her…

Aside from the first day, which was the peak of her estrus, she seemed to be satisfied with doing it once a day. During the day, she went to school normally, and once it got  to this time at night, she sought me out. That had been the recent routine between the two of us. 

The issue of the rigidity time caused by the Semen Sensing Reflex was, as expected, an exception on that first day when she was anxious due to being a virgin. Since then, the rigidity time had been steadily shortening. Yesterday, for the first time, it dropped below an hour and a half. Just as Yoshino-sensei had explained, the time would shorten with a sense of security. It seemed things were fine as she came to understand that I was always at home and wouldn’t run away. 

“Hey, don’t just take my clothes off on your own.” 

“It’s fine, isn’t it? This is today’s reward.” 

“…For which one of us?”

Yuka-san wordlessly pulled off my underwear. She understood that she would be accepted regardless. I didn’t resist either.

“Hehe. It’s getting big.” 

“Of course it is.” 

“These breasts were always just in the way, but I’m happy they’ve become useful.”

Incidentally, in this world, small breasts weren’t particularly prized. Breasts, as symbols of motherhood and femininity, were generally considered more attractive the larger they were. However, it seemed that once they reached an overwhelming scale like Yuka-san’s, they were considered excessive. My crotch was fondled, and she confirmed that I had become erect from the sensation of her breasts. Without resisting her urging, I turned onto my back.

“Wait, you weren’t wearing anything underneath?” 

“Well, yeah. We’re going to do it anyway. You’re erect, so it looks like I can insert it right away.”

Looking closely, Yuka-san was wearing no panties. Arousal fluid was overflowing from her crotch, making it clear that she was already fully prepared. She rubbed that slipperiness against the underside of my penis.

“I heard it was difficult to get boys in the mood, but Hikari-san is easy. I’m really grateful for that…” 

“…Is that so?” 

“It’s easy to make you come, too. Like this…”

Saying so, Yuka-san swallowed my meat rod with a squelch. It felt good to be enveloped in her vagina, which had a high body temperature from having just stepped out of the bath. She then began to slowly move her hips back and forth.

“Just by thrusting like this, you’ll come right away, won’t you?”

Being pointed out for my premature ejaculation, I didn’t know how to answer and fell silent. She might not have intended it as an insult, though.

“That’s what’s cute about you. Is the inside of my vagina really that comfortable? Oh, is it because I’m good at it?”

Making squishing sounds, she stepped up her attack while gradually increasing her speed. Without any special technique, I was about to come from just that.

“Ah, crap, wait…!” 

“Look, you’re already going to come. You can ejaculate. Ejaculate that ‘good stuff’ in me…”

Entwined by Yuka-san, who had sensed my impending ejaculation, I became unable to escape. There was nothing left to do but endure with all my might. Come to think of it, she said that before, too. I thought her phrase “good stuff” meant “proof that I had felt good,” but knowing the reason for her climax, it might actually mean “the liquid that makes her feel good.”

“Cum for me.” 

“Mgh…!? Nn!?”

As I tried to endure for even a second longer, my lips were stolen by Yuka-san, who intended to deliver the finishing blow. Her tongue invaded and licked around my mouth, and my strength drained away. That was the end.

“Nnuuuuuuuuh!!”

The white fluid I had saved up for a day was spat out, and Yuka-san, receiving it at her cervix, began to convulse violently. Her uterus relaxed and then contracted, gulping and sucking it all up. She, who had been boasting of her composure until just a moment ago, was now thrashing like a dying fish, yet she didn’t let go of my mouth, trying to suck the air out of my lungs.

Having regained my composure the moment I ejaculated, I hugged Yuka-san’s body as she continued to climax and gently stroked her hair. I waited for her to calm down for a while.

“Phew, phew… Th-that felt so good.”

With an expression of complete satisfaction, Yuka-san said that and rolled onto her side, falling fast asleep while still clinging to me. So that she could rest, I used the bedside remote to turn off the lights, leaving only the nightlight. I quietly checked the time on my smartphone screen.

Whether it was because she had become used to me, Yuka-san had started to show this kind of defenseless and unreserved side of herself. So far, it had always been Yuka-san who seek out sex. Of course, I wanted to do it too, but since she always came to me even if I didn’t say anything, things just became like this. 

Her libido was quite something. If I think about it in terms of a man from the previous world, you could say her libido was exactly like a monkey that just learned about sex. Thanks to the climax reaction to internal ejaculation, she was guaranteed to come, and if the plausible saying that “a woman’s climax feels better than a man’s” was true, it was no wonder her libido was even more than a normal man from the previous world.

Her being somewhat selfish in a way was also typical. Toward me, who was just lying there, she would get horny at night and had crude sex by just swinging her hips without thinking about anything. Once she cum and satisfied herself, she just went to sleep. 

It was not that she had any particular spirit to get better at it. Rather, since I ejaculated regardless, she was starting to think her own vagina must feel amazing and that she was good at sex. Lately, I also got the sense that she was feeling a sort of superiority in making me come with a kiss.

In a sense, I feel like a “tuna woman” dealing with a selfish, delusional boyfriend. Well, since I’m actually coming, that part is different.

Even so, it was not as if I had any complaints about Yuka-san. I actually found that delusional side of her endearing, and of course, her appearance when she was climaxing shamelessly was cute. Since she was satisfied with someone like me, naturally, I had come to like her too. 

I wonder… Perhaps the “tuna women” of the original world also loved their boyfriends in that way, and were happy and satisfied that they could make them feel good with their own vaginas without doing anything in particular? 

I hope that’s the case… What a kind world we live in.

My current standing right now was very comfortable. Here I was, internally finding fault with Yuka-san not actually being good at sex, but I wasn’t good at it either and I wasn’t trying to be. Why? Because I was allowed to stay like this and that was why I didn’t actually blame her at all. I truly believed it was fine for us to stay the way we were. 

I guess that’s what it means to know one’s place as a “tuna,” after all?
