I Went About My Life Normally Without Noticing It Was a World With Few Men, and Things Went Terribly Wrong - 3

Chapter 3: The Strange Nature of Women

ーーーーーーーーーーーーーーーーーーーー

At the moment of ejaculation, Yuka-san was likely climaxing as well. Her entire body spasmed and bucked so violently I worried she might be ill, yet her grip on me never faltered. On the contrary, the instant her uterus caught the semen, the strength in her arms and legs intensified to a staggering degree. It was as if there were another level of power I hadn’t imagined. I felt a fierce will emanating from her, something akin to fighting spirit or a thirst for battle, signaling that she had no intention of letting me go. 

Just who is this woman?

Even now, every time a slick residue of semen was squeezed out by the tightening of her vagina, Yuka-san’s body gave a little jolt. 

Men can feel the sensation of even a small amount of fluid passing through the urethra, but do women also feel the sensation of liquid splashing against the cervix? 

I didn’t think a woman’s body was that sensitive, but… Finding my hands idle, I instinctively hugged her back. The body temperature of her back against my palms was burning hot. Both my hands and the futon were already drenched from the sweat pouring off her. 

Should I feel disgusted? A stranger like this invaded my room, attacked me, and defiled me in so many ways. Strangely, however, I didn’t feel that way. The fact that her appearance was exactly my type played a large part. So did the atmosphere she had when she was calm. I liked her scent too, so physiologically speaking, she was a “pass.” Though, I’d really appreciate it if she’d lay off the kitchen knives, and the part about her rummaging through my mailbox was quite a turn-off. 

I mean, aren’t both of those completely criminal acts?

That said, now that it was over, I could say it was a bit of a lucky break for me. I was not particularly popular with women. Sure, I’ve had partners in the past, but they never lasted long. It had been quite a while since I last had sex.

When someone seeked me out so fervently, and that someone happened to be my type, it was only natural that I’d be won over or at least find it difficult to harbor ill will against her. On top of that, she was likely a virgin, yet she climaxed so intensely even with my premature ejaculating penis. She was like a woman out of a fantasy. It was only natural for me to think she was cute.

As long as I could persuade her never to commit another home invasion, I’d have nothing to complain about. As for the matter of finishing inside…

About that, I’m surely not the one responsible for it.

“Yuka-san?” 

“…………” 

“Hey.”

I called out to her as she remained stationed on top of me. I tried shaking her, but there was no reply. Did she actually fall asleep? Yet, the hold of her legs remained as forceful as ever. Even though I felt completely spent and unable to produce another drop, my penis was trapped inside her vagina and couldn’t be withdrawn. Despite having shrunk a bit after finishing, I was being squeezed so tightly that she seemed to be demanding more semen as if by inertia.

“Uu…”

She’s faking it, right? 

I gave her a few light slaps on the butt, but she didn’t react beyond a faint groan. I gradually increased the strength of the slaps, finally giving her a fairly merciless smack, but even then she didn’t wake up. Sweat sprayed from her rear, and my own hand began to sting.

I suspected she was faking, but even so, she was leaning her weight into me quite unreservedly. Usually, a woman wouldn’t want to be thought of as heavy, but she was slumped over me so limply that I felt her weight quite distinctly.

Maybe she really was asleep. She had been so incredibly excited, after all. I still hadn’t quite made sense of her motives, but she had gone through the extraordinary, violent emotional strain of preparing a knife and breaking in. Add to that the completion of her goal—the reverse rape—and perhaps after reaching the peak of psychological and sexual excitement, it was as if her internal fuse had suddenly blown.

What should I do? My eyes happened to catch my smartphone lying on the bed, and I picked it up. Under normal circumstances, the correct answer would be to dial the police right now… But a part of me didn’t want to turn this girl into a criminal.

Besides, the fact that I actually enjoyed myself was a bit of a sticking point. Would the police even take a “reverse rape” case seriously? The idea that such a cute girl would do that to someone like me would be the first point of suspicion. In the worst-case scenario, wouldn’t I end up being the one accused of rape?

“The woman was so strong I couldn’t shake her off, and she forced me to ejaculate inside her!”—who would believe a testimony like that? At best, they’d just think I was the one who wanted to finish inside. I’d be forced to explain the sexual situation in grueling detail, only to be doubted and told, “Well, you ejaculated, so you must have enjoyed it too.” Wouldn’t that be a “secondary reverse rape”?

No, I’d better skip the police. No man ever won that way. The smartphone screen showed 2:05 AM. I reflected on how barely forty-five minutes ago, before I left for the convenience store, I never could have imagined things turning out like this.

Looking back, everything was really happening so fast. I’d hurried through my shopping at the convenience store, so assuming it took about fifteen minutes to get home, in the remaining thirty minutes I had been attacked, argued, introduced myself, then was inserted into and made to ejaculate, after which I spent some time dazed. 

The sex itself probably didn’t even take five minutes. The fact that Yuka-san had been so excited and reached such a climax even from such a paltry act made her seem like an irreplaceable, dear existence to me. Yeah, turning this girl into a criminal was definitely off the table. When I softly stroked her head, she smiled faintly with an air of satisfaction. Even when drenched in sweat, she still smelled good.

Girls really are mysterious creatures.

Regardless, I was thirsty. I tried to stand up, but Yuka-san’s legs were still locked in a rigid grip that seemed impossible to peel off. With a bit of struggle, I managed to sit up. Since she was still clinging to me, we were in a “sitting position while facing each other” style. As I sat on the edge of the bed to catch my breath, the kitchen knife lying on the floor caught my eye.

“Seriously, if it weren’t for this, I’d have no complaints…”

Even though I’d decided not to turn her in, I couldn’t stop a sigh from escaping. For now, since it was scary, I decided to hide it. There was no guarantee that Yuka-san wouldn’t undergo another sudden change of personality once she woke up. I managed to stretch out my leg and kick it into the gap under the bed. It wasn’t a gap you could fit a hand into, so if she wanted to get it out, she’d have to find a long pole or move the entire bed. Now I could feel at ease.

Still carrying Yuka-san as she clung to me, I stood up and headed toward the brightly lit hallway where the lights were still on. I leaned over slightly to pick up the convenience store bag I had dropped earlier.

“Nngh!?”

The moment I put strength into my knees to steady my posture, the tip of my member seemed to gouge deep into her inner depths. She trembled, and the strength of her limbs clinging to me intensified again. When would she finally let go? My penis was just as stubborn;. It seemed to find the inside of Yuka-san’s vagina so comfortable that it showed no desire to come out. What an uncooperative son.

I took a drink and finally felt like myself again. I would have liked to give Yuka-san something to drink too, but there was nothing I could do while she was asleep. If she were faking, I’d bet on her giving up at this point to ask for a drink, but it seemed she really was sound asleep. Or rather, she had lost consciousness.

Even so, now that we were in a brightly lit area, I could get a clear look at her body. Her body  was truly provocative indeed. Her white skin was without a single blemish. Her massive, drooping breasts were of a weight and size that could never maintain their shape without a bra. Dangling such enormous things, she must have trouble even seeing what was directly beneath her. I, too, was blocked by those breasts and couldn’t see our firmly locked junction.

Feeling a bit regretful about that, I turned on my heel to return to the bed, only for something chilling to catch my eye. A trail of blood droplets followed the path I had just walked! I trembled for a moment, wondering what on earth had happened, but it was nothing so dire. It was just Yuka-san’s hymeneal blood.

If it was like this here, she must have bled quite a lot. Even if only for a short time, we had moved quite violently. She didn’t seem to feel any pain, but while I worried if she was alright, I also resigned myself to the fact that the bed was going to be a disaster. The sweat was also incredible. It hadn’t bothered me until now, but after getting up once, I felt reluctant to lie down there again.

That said, there was nothing else I could do in this cramped room. After putting my lunch box in the refrigerator, I gave up and lay down on the bed. It was cold and wet with fluids, though I couldn’t tell which were mine and which were Yuka-san’s.

◆◆◆

I decided to run from reality. I didn’t want to clean the bed or the floor right now and postponed the problem. I could just do it with Yuka-san after we woke up in the morning. It was not like I was the only one who made a mess. Anyway, I intended to sleep, but I couldn’t because Yuka-san was still slumped on top of me. Honestly, I was impressed she could sleep like this.

Left with no choice, I browsed the internet on my smartphone. It was then that many mysteries were solved.

Listen carefully, okay? It seems I’ve somehow ended up in a “reversed world” where men are incredibly few and precious…

“Why?”

Even though I muttered it aloud, there was no way to know. But let me voice one more complaint.

“……The timing is way too bad.”

Looking back now, that sensation of the world shaking around 1:20 AM, just before I went to the convenience store, must have been it.

Why did it have to happen in the middle of the night? If it had been during the day, I would have noticed the moment I looked outside that everyone around was a woman and realized something was wrong. I would have checked the news immediately. But because it happened late at night, I only happened to see Yuka-san and the convenience store clerk. While I felt a slight sense of unease that a young woman was out so late, I never would have dreamed such a fantasy-like event was occurring.

I had read a few stories like this, but didn’t these things usually start with an awakening? Like waking up in the morning to find the world reversed, or waking up from unconsciousness after an accident or illness. It was usually one of those two. Then a sister or a nurse explained the situation to you. To have it happen suddenly while I was alone at night… 

Oi, you really shouldn’t ignore the common tropes like that.

So, the fact that I went outside defenseless and ended up like this wasn’t because I was being thoughtless. Nobody could have predicted this, and it wasn’t because I wasn’t being careful enough. I was just unlucky. Thus, the proof was complete.

Now, as for why I noticed the gender ratio and the reversal of sexual morality… Of course, it was not like I suddenly searched for those specific terms. When I opened the browser on my phone, I first searched for “dangerous day pregnancy probability.” That was the start of the feeling that something was off. The term “dangerous day” didn’t seem to be used in this world at all, and the search results were all strangely off-target.

Well, it’s slang after all.

I thought, and switched the search to “ovulation day pregnancy probability.” And boy, was I surprised. It was a staggering 99.99%. 

No way, that can’t be right. 

My memory was fuzzy, but wasn’t it like 20 or 30 percent? I searched to confirm that, but every site said roughly the same thing. As I kept digging—assuming this wasn’t one massive prank involving the entire internet—I came to realize that the biology of women in this world was different from what I knew.

Apparently, if a woman had sexual intercourse on her ovulation day, she had a 99.99% chance of becoming pregnant. This was incomparably high compared to other creatures where males and females existed in equal numbers, but in the case of humans, it was the result of evolving to ensure that not a single drop of a precious male’s sperm would be wasted. Furthermore, when a woman sensed the ejaculation of her male partner, her arms and legs would lock up, and she would exert extraordinary strength to ensure the male never escaped. This was called the “Semen Sensing Reflex.” 

There were individual differences in this reflex, but normally it would be hard to escape for several minutes to several dozen minutes after ejaculation… I also thought this was absolutely ridiculous, but at the same time, it also made sense. The proof was here, after all. Yuka-san, who was still on top of me right now, refused to let go of my penis. It turned out it wasn’t because she had abnormally trained muscles or the fact that she was a “menhera.” Rather, every woman in this world was like this. 

That is, if the information on the internet is to be believed.

Conversely, men seemed to be much weaker than the ones I knew. Their average build and muscle strength were lower than in the previous world, and above all, they had no sex drive. You could guess the specs of their penises. Since I hadn’t changed at all, my height of 175cm—which should originally be only slightly above average—seemed to be considered quite tall here. As for sex drive, I even felt like mine had strengthened. The penis inside Yuka-san’s vagina wouldn’t calm down at all. 

Well, I’ll reserve judgment on that since it’s possible her pussy is just that amazing… 

Wait a minute? If the average man had a small penis with thin semen and a low ejaculation volume, then the meaning of the data I saw earlier changed. If even a shallow insertion and a small amount of sperm resulted in a 99.99% pregnancy rate, then the probability that Yuka-san got pregnant from my ejaculation, which reached her cervix… There must be several more nines following that decimal point…

For a moment, I felt faint, but on second thought, that was just a margin of error. No matter how many nines you added, the difference between 99.99% and 99.999999…% was less than 0.01 points. Either way, it was better to proceed on the assumption that Yuka-san was already pregnant with my child.

My child? Seriously? 

Saying it out loud made the impact incredible. I was still only a junior in college. What was I supposed to do? I hurriedly started looking up the costs of childbirth, childcare, taking a leave of absence from school, and marriage. There were simply too many things to look into. It was getting out of hand.

Driven by a sense of crisis, I spent about an hour desperately researching… But to put it simply…

Let’s just say it looks like things will be okay. Because it’s a world where men are precious, it’s kind and easy for men. Men don’t have to feel responsibility. That’s how it is.

Marriage, huh… At first, the future of taking responsibility and marrying Yuka-san crossed my mind, but being told I didn’t have to actually made me more conflicted. It was difficult precisely because there was room for choice. 

Look, it’s basically the same as being asked what you want for dinner and “anything” being the most troublesome answer. 

It was a problem serious enough to make me want to joke about it like that. What should I do with her? Then again, this was not a topic I could decide on my own. I would have to hear her will first.

“Is she ever going to wake up?”

Or rather, I didn’t even care if she woke up or not, I just wanted her to let me go. It had been two hours, and I thought I’d be able to pull away by now, but for some reason, her strength hadn’t faded. My muscles started to ache. I understood this was a physiological phenomenon called the Semen Sensing Reflex, but was it within the range of individual variation for it not to release after two hours, when this phenomenon normally lasted around several dozen minutes?

The Semen Sensing Reflex was profound. Just as Yuka-san sensed I was about to climax and forced an ejaculation, this phenomenon wasn’t triggered after actually receiving the ejaculation, but was said to predict the moment a man was about to ejaculate. 

You might think it sounds like the occult or ESP, but it’s not quite like that!

Any man knew beforehand when he was about to ejaculate, right? I didn’t know why, but a man just knew naturally. It was like instinct, just as you knew how to move your fingers or how to walk without falling, any healthy person knew, but they couldn’t explain the mechanism. That didn’t mean the mechanism hadn’t been discovered though. I was certain this instinct was written in detail in medical or sports science books.

Anyway! Just as a man understood the sensation of ejaculation, women in this world sensed the minute movements of the penis inserted into the vagina and realized that the man is about to ejaculate shortly. That sensation was something they couldn’t explain themselves, but that didn’t mean they had super power. It seemed to be common knowledge in this world, so I was certain this thing was scientifically explained in books.

When they sensed the sign of ejaculation, they reflexively put strength into their legs and arms, exerting an incredible force like “herculean strength.” It seemed they themselves couldn’t control it with reason. No matter how much a man struggled or how much they might feel sorry for him, and even if the woman herself tried to let go, she supposedly couldn’t release her strength. The women of this world sure had a strange ecology.

The muscle strength at this time was truly fearsome. In fact, there were experimental results like this: Suppose a woman has her legs spread wide as if for a pelvic exam at an obgyn and her hands and feet are fixed with equipment. In this state, if a man is made to insert and ejaculate to trigger the reflex, even an average woman will easily tear apart something like a rope and exert enough force to slightly distort even iron fixtures. Of course, you can rest assured that the experiment was conducted with the proper consent of both parties.

Sexology, is it? 

It was interesting that people seriously and scientifically research such erotic topics. I didn’t usually read articles in the science field, but I found myself engrossed in articles and papers like this. While doing so, the long-awaited sleepiness finally arrived, and I fell asleep without resisting it.
