I Went About My Life Normally Without Noticing It Was a World With Few Men, and Things Went Terribly Wrong - 20

Chapter 20: A Secret Technique for Multiplayer Play

ーーーーーーーーーーーーーーーーーーーー

“It smells kind of strange in here. …Oh? You are…”

The girl who entered the elevator, which was thick with the scent of sex, had an innocent look about her, like she was still in high school. But since she was living alone in this apartment, she was likely a university student.

Looking at her, she seemed to recognize me, and I remembered her too. A week ago, when I was being carried away in the ambulance with Yuka-san, she was one of the people I had run into here on the first floor.

“Hey, do you know this guy? Anyway, you’re coming with us for a bit.”

While the girl and I were staring at each other, the elevator had reached the sixth floor before I knew it. Natsumi, who had completed her reboot, had apparently pressed the button quickly. It must be the floor where one of the three gyaru lived.

“W-wait a minute. What is this! I’m going to my own room…” “

Just come along and give us a moment. Kei, here’s the key.”

Regardless of my inner thoughts, the gyaru felt that since she had witnessed them gang-raping a man, they couldn’t just let her roam free. I didn’t know how they planned to silence her, but Natsumi pulled me—still carrying Leona—and the new girl out of the elevator, while Kei quickly unlocked the door and led us into the room. Room 601, directly below my own.

“This is Leona’s room. Is Leona… okay?” 

“S-so good… A man’s cock is insane…”

The owner of the room seemed to be Leona. She was still showing an ahegao face in my arms. At Natsumi’s instruction, I laid the still-twitching Leona onto the bed. However, since my waist was still held fast by the Semen Sensing Reflex, I couldn’t pull away. Consequently, I ended up hovering over Leona, pinning her down in the missionary position.

Come to think of it, it seemed they didn’t call this the “normal position” in this world. That was because it was considered normal for the woman to be on top.

Just as Yuka-san and Celly had done as if it were natural, the cowgirl position was thought to be the most standard posture, and that was what they called the “normal position.” Of course, because it looked like riding a horse, the term “cowgirl position” also existed, but it was used as a perfect synonym for the normal position.

So, as for the position Leona and I were in now, it was apparently called the “submissive position,” because the woman, who was supposed to be the dominant one, was being made to yield. If I were to lift the woman’s legs from here, it would be called the “flexed position” or “leg-raised position,” just like in the original world I knew.

Even though names like that existed, the weak men of this world rarely practiced them. Rather than being something initiated by men, it was regarded as something that the not-so-numerous, hardcore M-type women deliberately made them do. Seeing Leona in such a shameful, perverted position, her gyaru friends looked as if they had been struck by lightning.

“Haah… G-give me more…” 

“L-Leona…”

While pinning Leona down in that submissive position, I ground my hips, wondering if I could pull out soon. Faced with the sight of Leona begging for more with a blissful expression, the others looked at her with pity, yet also with a hint of excitement.

Soon enough, the rigidity wore off and Leona’s legs opened up. It seemed the information that the rigidity time for some people was only a few minutes was true. I had also seen info that it lasted longer for “menhera” types, but the opposite might be true. For an easy, straightforward woman like her, the rigidity period might be exceptionally short.

Leona remained with her legs sprawled wide, twitching even after my penis slipped out, while my penis shone glossily with her arousal fluid. The women looking at them back and forth swallowed hard.

“Does it really feel that good…?”

It was Kei who spoke, looking red-faced yet still half-doubting. But Natsumi, who had shown interest from the start, was quick to act. To my surprise, she stripped off everything from the waist down, rolled onto the floor in the same posture as Leona with her legs open, and directed her defenselessly exposed private parts toward me.

“P-put it in me, too…”

It seemed she was an extreme masochist, which should be very rare here. To think that was her true nature… You really couldn’t judge a book by its cover. Kei stared at her friend’s hidden side, speechless.

As for the last person here, the girl who had been brought along, she remained silent as if she were seeing something strange she had never witnessed before. It wasn’t a look of disgust, but rather a very calm observation of the situation, like someone interested in a mysterious, rare species of animal they couldn’t understand.

Well, in this world, seeing two women lined up and spreading their legs for a man on their own must certainly be a “rare sight.” Deciding to leave her be since she wasn’t running away—though since it was the gyaru who would be in trouble if she escaped, it wasn’t really my concern—I crawled over Natsumi, who was dripping arousal fluid longingly.

When a woman is spreading her legs because she wants my penis, there’s no need for extra words. 

Silently pressing the tip of my penis against her slit, I plunged into Natsumi’s vagina in one breath without hesitation, making her jump and shiver in surprise.

“Nnnnnnnnh!!”

Natsumi froze for a moment from the sharp pain, but reached a light climax immediately after. It was probably because the semen remaining in my urethra, which hadn’t been fully discharged into Leona, shot out inside of her. Since she climaxed, she must have sucked in a fair amount of semen. This fact alone made it certain she would get pregnant.

Incidentally, the Semen Sensing Reflex didn’t occur. That must be because my penis wasn’t currently on the verge of ejaculation. It was merely the remaining sperm coming out. The rigidity reaction, where the vaginal walls sensed the precursor to ejaculation, and the climax reaction, where the cervix sensed the semen, were separate things. The latter had no name yet since it was only just discovered. Once the experiment I was planning with Yoshino-sensei took place and she published her paper, the world would come to know about it, and there may be a chance to rename the former, which was currently a misnomer. If a need to distinguish them arose, it was only natural the names would change.

Feeling aroused from Natsumi’s moans, which sounded like a normal woman’s, I hammered my hips against her. Come to think of it, this was the first time I had done it in the “normal position” since coming to this world. I should consider asking Yuka-san and Celly to try this next time. I was a little scared of what they might think, but I had a feeling Yuka-san might actually accept it quite easily if I just ask.

“H-hey, do it to me, too…”

While I was pumping Natsumi while thinking about other women, Kei, who had been left out in the cold, tugged on the hem of my shirt. She seemed interested, but couldn’t quite take the plunge, fidgeting while still fully clothed. Of course, I had intended to do her next anyway.

“Pardon me for a second.” 

“Wah! Wh-where are you putting your hand!” 

“I’m going to insert it here anyway, so I’m just checking.”

I thrust my hand under Kei’s skirt, shifted her crotch aside, and felt her private parts. Well, she was actually quite wet. I wonder if my dick would fit into her. But she didn’t seem as intensely aroused as Leona or Natsumi, so she might be feeling a bit of a pain.

I then thought of a good way to avoid causing pain and proposed it to Kei while continuing my strokes into Natsumi.

“I know, try straddling Natsumi-san like this.” 

“Huh!?”

Is threesome sex not practiced much here? 

In a society where polygamy was the norm, I thought this position would be generally known, regardless of their personal feelings. Ah, I overlooked the weakness of male stamina. 

Even in polygamy, a play style where you handle multiple women at once might be unthinkable for a man. Good grief.

“H-hey, I don’t have that kind of hobby.” 

“Just do it. It’s necessary so it won’t hurt as much.”

When I encouraged the hesitant Kei by making her pussy squelchy with my hand, she finally resigned herself. She crawled over Natsumi, and showed me her buttocks. 

Oh, this is quite a magnificent view. 

I had started to feel the reality of polygamy once Celly was added, but doing it with two women at once was a first, and the excitement was overwhelming. While poking Natsumi’s pussy, I toyed with Kei’s pussy above her with my hand. My urge to ejaculate rose rapidly.

At that moment, Natsumi—who sensed the impending ejaculation from my penis and triggered her rigidity reflex—snapped her legs shut, firmly holding the waist of Kei, who was layered on top of her.

“Natsumi!? What are you doing, let go!” 

“N-no, that’s not it! It’s the penis!”

The two were in chaos. Especially Kei, who hadn’t had the penis inside her yet, found it incomprehensible why Natsumi was suddenly clinging to her. I was surprised by how much better this worked than expected. It turned out that if I inserted into one woman while two were layered like this, the instinct of the one being penetrated would misidentify the woman in front of her as the target to be captured.

Whoops, I don’t have time for leisurely analysis. I’m about to ejaculate. 

I pulled my penis—which had reached its peak in Natsumi’s pussy—out, and immediately shifted Kei’s panties and thrust it into her slit.

“Nnu!?”

The moment the tip of my penis entered, Kei also sensed that I was on the verge of ejaculation and triggered her rigidity. Her legs, naturally, bound Natsumi’s body.

“W-wait, don’t tell me…”

The one on the bottom of the intertwined human dolls—that was, Natsumi—looked at me with horrified eyes, as if she had glimpsed the future a few seconds ahead. It was surely exactly as she imagined. The tip of my penis reached the very back of Kei’s vagina. Into the vagina that tightened from the pain of the moment her maidenhood broke, and against the cervix that had descended in anticipation of ejaculation, I spat out my semen.

“Huaaaaaahhh!?” 

“A-ah, no way, that’s cruel… The sperm meant for me…”

Natsumi, unable to move while being squeezed by Kei as she climaxed, shed a tear as she watched me ejaculating into Kei.

Seeing that, I actually felt a bit sorry for her, and I put the remainder of the ejaculation into Natsumi. She might be angry at me later, but for now, she seemed to be climaxing from the leftover semen and forgetting everything else, so I decided it should be fine anyway. As a side note, I pulled Kei’s panties back into place and squeezed her labia majora together to seal it so the semen wouldn’t leak out.

This method of avoiding being restrained by sandwiching my penis between two women… Since I was still free and both women were simultaneously incapacitated, I could say this was an extremely convenient and powerful technique. However, there was a high risk of being resented by both parties, as I essentially used the instinct meant to make a man ejaculate to play with their bodies.

Well, since these were just random women I wasn’t planning on making my girlfriends, I tried it anyway since a good opportunity like this wouldn’t come twice. However, I should probably avoid playing around by layering Yuka-san and Celly. 

This might be due to illogical feelings, but both Yuka-san and Celly seemed to want to hold me when they climax from internal ejaculation. To be forced to hold someone else as a substitute would naturally make them angry.

Or, there might be a chance if Yuka-san and Celly became very close as female friends… But even if they consented, I would then have to watch the two of them hugging each other tightly for several dozen minutes, and I might get lonely being left out in the cold.

So, as expected, it seemed difficult to find the right time to use it. This was a secret technique reserved for when the woman was someone I didn’t particularly care about.
