I Went About My Life Normally Without Noticing It Was a World With Few Men, and Things Went Terribly Wrong - 13

Chapter 13: Orgasm Experiment

ーーーーーーーーーーーーーーーーーーーー

“Ah, I’m sorry, but I won’t do as a subject myself. Though my husband has passed away, I remain faithful to his memory. Furthermore, I’ve long since gone through menopause, making me unsuitable as a test subject. Above all, I am outside the scope of Wago-kun’s sexual interest.”

I felt a sharp sting from her words. Perhaps she was still bothered by the fact that I hadn’t gotten an erection when she touched me earlier.

Still, her sense of chastity seemed remarkably firm. I suppose because men were so rare, women cherished the one man they were lucky enough to encounter. Well, if I were in the position of her late husband, Mr. Yoshino, I wouldn’t be too thrilled about my wife touching a stranger’s penis, even if she was a doctor. Since I’d feel like it was an act of infidelity even knowing it was purely professional, the professor had been outside my “strike zone” from the very beginning as well.

“Speaking of sexual interest, my daughter Celestine is a perfect fit. After all, the moment he laid eyes on Celly, his penis grew quite large.” 

“Wait!?”

She made an outrageous statement. It was technically true, but her way of saying it felt malicious! I hurriedly looked at Yuka-san. She was smiling, so was she okay with it…? Well, she already understood that I would eventually take other women, and according to social common sense, it was only natural. It might be me who was being strange for feeling guilty.

The real issue, however, was Celestine-san herself. If she didn’t consent, the conversation would end there. I looked over at her with a bit of anticipation, wondering how she’d react. Her mother, Yoshino-sensei, was egging her daughter on. Apparently, even proverbs were gender-reversed in this world.

“What do you say, Celly? There is a man right here getting an erection for you. As they say in Japan, ‘It is a woman’s shame to leave a meal untouched when it is served.'” 

“Yeah. I want to do it.”

Wait, just like that? I was surprised by how easily Celly agreed. 

Is this one of those convenient things where the hurdles are incredibly low because men are precious? 

I wondered, but it didn’t seem quite like that. Something was off about Celly’s demeanor.

“Hm. Celly, has your heat started? It should still be five or six days away.”

It was just as the professor said. I had become accustomed to seeing it with Yuka-san, but Celly, who had been calm moments ago, was now flushing red and exhaling hot breaths. She stared fixedly at me and my penis as if she were about to pounce at any second. Still, why did the professor know her daughter’s menstrual cycle? And none of the women around her seemed to find it odd. They accepted it as a matter of course.

…I was told later that in this society, information regarding menstruation was not a taboo at all. It was standard for schedules to be shared at workplaces and schools. Well, this was a society run almost entirely by women after all. Being open about periods was a natural development. And because they understood the hardships of their own gender, they automatically received time off during their periods. Women from my old world would probably weep with envy if they heard that. At any rate, the cycles had to be known for this reason.

Furthermore, because approaching a man during heat could potentially trigger a crime, those in professions that interact with men are strictly removed from duty during that period. Today, the crew members who rushed to my emergency and the hospital staff who treated us were all presumably chosen on the premise that they were not in heat. This was another reason why cycles needed to be tracked at the workplace.

Thus, Yoshino-sensei had called the students after confirming they weren’t currently in heat before meeting me. The fact that Celly was in heat now was what struck her as suspicious. Sensei, who had been deep in thought with her hand on her chin, muttered as if she’d realized something.

“Could it be… No, if that’s the case…! Honestly, how many historical discoveries are going to emerge today alone!” 

“Professor, what do you mean?” 

“Ah, this is merely a conjecture, but… Celly was stroking your penis and intently smelling it and its secretions earlier. There is a possibility that your presence… Accelerated her ovulation.”

It was true that before Yuka-san and the others arrived, Celly had given me a handjob nearly to the point of ejaculation and observed my penis from up close. Just a moment ago, she was even smelling the scent of the fluid on her hand. 

But can that really accelerate her ovulation…?

Celly was fidgeting restlessly. If I was allowed to do it with a beautiful half-Japanese girl like her, I wanted to get started quickly. Our eyes met, and we exchanged a silent intent to begin. Right then, an unrefined voice cut in.

“Wait a minute! We won’t allow such a thing in front of the police!” 

“Isn’t this an experiment we’re conducting for the sake of the police?”

Yoshino-sensei spoke up, but the detectives refused to back down, insisting on stopping us. 

Though, Professor, you just want to satisfy your own academic curiosity, don’t you?

Just as I thought it would turn into a heated argument, Sensei started rummaging through her bag. She pulled out a tablet, operated it for a moment, and declared.

“This is an official experiment for academic purposes, conducted by the Yoshino Laboratory of Sexology. I’ll have Wago-kun and Celestine sign the experimental consent forms.”

She showed us the tablet screen. 

Even consent forms are digital these days, huh?

I had participated in psychology experiments at university before, and this had similar cautionary notes, along with fields for name, age, and a handwritten signature.

The experimental procedure was described as inserting the male subject’s penis as deep as possible into the female subject’s vagina and ejaculating at that point. The research objective was stated as confirming whether this would trigger a sexual climax in the female subject. There were explanations about the handling of personal information, and a clause stating that subjects could request to stop at any time if they felt uneasy. 

But stopping right before the finish line during sex sounds like the ultimate punishment.

I checked one point regarding the setup of the experiment with the professor.

“Um, it says ‘video recording’ here…” 

“It’s to record the subjects’ reactions as data. Of course, that information will be handled with strict confidentiality. It’s written right there, isn’t it?”

Good grief, this is practically a porn shoot. 

A smartphone seemed sufficient for a camera, and Yoshino-sensei was giving filming instructions to the remaining two students as research assistants. She intended to film from three different angles including her own.

“You, from this angle, make sure Celly’s whole body is in the frame. You, be careful not to get yourself in the shot and zoom in to film the area around the union of the two.”

Preparations proceeded at a breakneck pace. During this time, Celly and I read the consent form carefully and signed. Celly was excited due to her heat. I wondered if there was an issue with consent in this state, but then I realized the logic was sound. After all, if actions taken during heat lacked consent or legal capacity, then raping a man during that time would go unpunished. But since people are actually held criminally liable, it is considered that one has social responsibility for their judgments even during heat.

Celly stripped off her clothes and climbed onto the bed. It seemed she was becoming fully nude so that every detail like the flushing of the skin and the erection of the nipples, could be recorded as deciding factors for the climax.

She had D-cup-sized, relatively modest breasts topped with light pink nipples and areolae, characteristic of her Caucasian heritage. Seeing them made my penis grow even larger. Since I’d been teased and stopped right before the end several times by her handjob, I felt like I might ejaculate at any moment.

“We will now begin the experiment. Officers, and Shirasago-kun, I’m sorry, but could you please leave the room? You may request the experimental results as data later through the proper procedures.”

Even the police couldn’t do anything when told by a professor from Japan’s top medical research institute that this was an official experiment. They prepared to leave, pulling Yuka-san’s wheelchair. But then I remembered—though I’d nearly forgotten in my excitement over the prospect of ejaculating inside Celly—that my main goal was to clear Yuka-san’s name right here and now.

“Excuse me, Professor, and Celly too. If possible, I’d like the detectives to stay and witness this.” 

“Hmm… As long as they don’t interfere with the filming, I don’t mind.” 

“I’m fine with it too.”

My request was granted easily. Wasn’t Celly embarrassed about having her sex—and her loss of virginity, at that—witnessed? Perhaps she was too excited by her heat to care, or maybe she was the type of girl who felt arousal from being watched. If so, I could sympathize a little with her.

“I have a request as well.” 

“…Yuka-san?” 

“May I hold Hikari-san’s hand? I won’t interfere with the experiment.”

Yuka-san, who had been silently watching the turn of events, finally spoke up with a demand. It seemed she couldn’t simply feel nothing about me having sex with another woman. She turned to me with a smile that seemed to want to say something. 

…Wait, does she know that I was holding the trainee Fukakusa-san’s hand during that internal ejaculation when we arrived in the ambulance?

“Even if it’s for an experiment, my husband is about to be made to ejaculate. As his wife, surely it’s fine for me to stay by his side?” 

“That’s true. I’ll allow it.” 

“Thank you.”

We’re not married yet, though. But we’ve done plenty of things to get her pregnant, so I guess it’s a common-law marriage. 

I didn’t particularly feel any anxiety, but considering the weakness of men in this world, I might be seen as a pitiful figure who was being forced to be violated and made to ejaculate for the sake of experimental cooperation.

The filming was done from three points: Celly in the cowgirl position filmed from the front-left and front-right, and a zoom-in on the union from behind my head. Moving the hospital bed would be a hassle, so I just moved the pillow and lay down with my head and feet reversed. This allowed for a shot from above my head—essentially a “point-of-view” angle.

While paying attention to the camera positions, Yuka-san sat right next to my head and held my hand.

“Good luck with your ejaculation.” 

“Y-Yeah…”

After encouraging me, she also spoke to Celly, who was straddling me and about to insert my penis into her pussy. Was she about to give Celly a warning?

“Yoshino-san, was it? As his primary wife, I shall witness the moment my husband impregnates you.” 

“Okay. Thank you.”

Is that something you say thank you for? 

Celly spoke concisely, her head already seemingly filled with nothing but thoughts of my penis. Yuka-san added one more word of caution to her.

“Hikari-san’s member is incredible. Prepare yourself.” 

“I know. But I’m confident in my composure. Even if he ejaculates, I won’t lose my head. I’ll report exactly how the sensation of the semen being released feels.”

As a record for the research and as evidence to clear Yuka-san’s suspicion, Celly wanted to leave a record of what she felt during the internal ejaculation. Whether she was truly “composed” while in heat was highly questionable… At the very least, she hadn’t tried to rush and attack me like Yuka-san had, nor had she raised her voice yet. Naturally, there are individual differences in heat as well.

And so, the filming finally began. Celly gripped my penis and slowly lowered her hips. The tip brushed against her hairless slit, and she searched for the vaginal opening while making a lewd squelching sound.

“Is it here? Huff, huff…”

She seemed to have found the spot for insertion, and her hand gripping my penis stopped moving. However, her hip movements stopped as well. Though Celly was usually expressionless, I could tell she had reached a state of extreme tension and anxiety.

But if she didn’t insert it soon, I was going to go just from her hand gripping me. I’d been teased and stopped so many times already. If things stayed like this, I’d pathetically misfire and fail the experiment. I really didn’t want to become a laughingstock like that, so I endured with all my might.

“Yoshino-san, I know you’re scared, but please hurry. Otherwise, Hikari-san will…” 

“I-I understand.”

Truly, a difference of a single day’s experience. Yuka-san, who was more experienced by exactly one day, seemed to have sensed from my expression or something that I was about to ejaculate. Prompted by those words, Celly finally made up her mind and lowered her hips. Just two or three centimeters. Only the glans was tucked into Celly’s narrow pussy, just enough that the hymen wasn’t broken yet.

The anomaly occurred at that exact moment.

“Ah… unyaaaaaaah!?” 

“Celly!?”

Celly, who had let out a momentary, silly cry, suddenly moved her body. Her legs snapped shut, sandwiching my waist. It was the Semen Sensing Reflex. She had sensed with her internal membranes that I was already about to go. Directly against her own will, the strength of her own legs forced my penis deep into her vagina. Her hymen tore with a series of pops, and she let out a groan of agony.

“Kh…! Wait, un moment… kuuuu…”

Sweat beaded on her face as she endured the pain. Perhaps because she was calmer than Yuka-san even in heat, or because she was a bit more petite, the pain was apparently quite intense.

Nevertheless, her instincts made her vagina peristaltically undulate. From bottom to top, the vaginal walls rippled rhythmically as if it was wringing out my semen eagerly. Her insides were coaxing my ejaculation. Her cervix descended and latched onto the tip of my penis.

Ah, the ejaculation is coming…

 Even without me putting it into words, Celly sensed it through a woman’s instinct, and Yuka-san through a woman’s experience. The other women around us also sensitively picked up on the change in the air, and everyone watched the moment with bated breath.

“Yoshino-san, the ejaculation is coming. Make sure you catch every drop.” 

“Ah, n-no. If you let out that much ejaculation…!”

I could tell a massive amount of ejaculation was coming. Celly seemed to realize it too. Celly’s eyes, filled with the fear of the frenzy she was about to enter, looked at me. Staring back into those eyes, I released my seed into her cervix with every ounce of my soul.

“Ngoooooooooh!!! Oh, oah… gah…!”

The sudden beast-like scream made all the spectators’ hair stand on end with shock. I heard the sound of the assistant filming from the front-left dropping her camera in surprise.

I couldn’t see Celly’s expression as she arched back and stared at the ceiling, but I was certain it was something one could hardly look at directly. Her white throat was exposed, her pink nipples were standing tall and erect, and sweat was pouring from every inch of her skin.

Even Yoshino-sensei, who was barely managing to continue filming, widened her eyes in shock, looking in disbelief at the unseemly display of her daughter, who was usually so quiet. The detectives also stood frozen with faces as if they’d seen something terrifying. Even Yuka-san, the only one who had already experienced this climax, was startled. Was she aghast to learn that she had been like this? No, Yuka-san hadn’t climaxed with such a hideous voice, so she should rest easy.

Each time the remaining semen was sucked out into her tightly squeezing vagina, Celly gave a jolt and convulsion that made the watching women shudder. Everyone remained speechless as if in awe, yet they couldn’t seem to look away from the sight of Celly’s beautiful limbs trembling with pleasure. All of them were staring fixedly as if frozen in time.

“Wago-san!? What happened!?”

I wonder how long time had passed. A nurse who had apparently heard Celly’s scream from the same floor burst into the room, and finally, everyone’s paralysis was broken.
