A Love-Comedy Comes Along with Sex! ~ It Seems the Human Race Will Perish Unless I, Who has Zero Dating Experience, Use my Cheat Penis to Create a Harem and Ensure the Proliferation of Our Descendants ~

Chapter 66: Son, Sleep.

The laboratory is made of a one-way mirror, so the room’s interior is visible from the outside. There are dozens of researchers outside the room, busily working. This facility is for them to monitor the room’s situation without missing a single detail.

“Finally, we can conduct a proper experiment.”

Doctor, the experiment fanatic, grins lewdly. In fact, she had been planning this experiment for quite some time, and she was very excited that it had come to fruition.

“Thank you for your hard work, Doctor.”

Among the people watching over Hiro, there are also Doctor and Aizawa. The two of them are observing Hiro with slightly tense expressions.

“Wow, it’s a monster. It’s beyond human common sense.”

The girl-like Doctor, who is called Doctor, sighed as she looked at the numerous experimental results submitted to her.

“Adam is that amazing, huh?”

There are still many things we don’t understand about Adam. Doctor has the most knowledge, but even she was sweating at the sight before her.

“Adam is amazing, but that boy is abnormal.”

“Hiro-sama… you say?”

“His compatibility with Adam is too high. Normally, there should be some resistance between Adam and his body tissues, but they’ve fused perfectly. That’s dangerous.”

“I see…”

For Doctor to say that much. The researchers around her couldn’t help but hold their breath. Some of them felt fear towards the boy Hiro, while others felt hope.

“Well, everyone. Do you remember the main purpose of this experiment?”

Doctor gives a glance to the researcher who looks the most docile nearby.

“Umm… the purpose of this experiment is to investigate the changes in Hiro-sama’s body due to Adam’s influence…”

“Come on! That’s too long! In short! The erectile power, the amount of semen, and the recovery power. We want to know how much they’ve changed. That’s why we prepared such a large number of females…”

However, Doctor couldn’t continue her words as she watched the trampling drama unfolding before her eyes.

This experiment had been planned a long time ago. Therefore, they had taken every precaution to ensure the experiment wouldn’t fail, mobilizing people and money to the fullest extent.

“Aizawa-chan, do we still have any spare females?”

“Yes… there are about ten left.”

“Let’s deploy them soon. At the same time, we’ll recover the pathetic females who are knocked out already. We’ll have those who seem to be able to recover to try again.”

“Understood.”

It goes without saying that the researchers are trembling. They are trembling at Hiro’s, the experimental subject’s, virility.

One of the researchers checks the results of the tally and mutters.

“A monster…”

—Report of the Findings—

Total Number of Mating Partners: 68

Hiro’s potential was far beyond anyone’s expectations. His stamina was inhuman. And it wasn’t just that. All the women he had sex with had fallen under Hiro’s spell. Although we had given all the women aphrodisiacs, they had been still directly affected by Adam’s effects, and they were craving Hiro to the point of madness. From the outside, it looked like a zombie movie. He had knocked out almost all of them single-handedly, and he was truly terrifying.

“Five hours and thirty minutes have passed since the start of the experiment!”

“Okay, okay. We’re almost at the end of the experiment.”

Doctor looks at Hiro with shining eyes. Her expression is full of hope.

In my confused consciousness, I was somehow still thrusting my hips. I didn’t know why I was there. Why was I naked? Why was I thrusting my hips? Who were these women?

The female bodies lying on the ground were twitching all over, and white liquid was overflowing from their vaginas.

“I’m… going to cum…”

I don’t know how many times I’ve ejaculated. I’m emotionless, and I release my semen into a beautiful woman I don’t even know. She has a beautiful appearance that could be an idol, and she lets out a scream-like voice as she cums inside at the same time I ejaculate. She collapses on the bed and loses consciousness.

Finally, I can sleep… I thought that moment. But then, one after another, more beautiful women climb on top of my crotch. My son, who is my parent, has no time to sleep, and his penis becomes erect again.

My son becomes erect without my consciousness. And then he has sex with another woman. How many times has it been now? My penis feels like it’s about to break.

This is truly a living hell. It’s a harem sex hell. Normally, I would enjoy sex with beautiful women, but now it’s only painful. Oh, I feel like I’m just a sperm machine.

“Damn! I’m cumming again!”

“Ahh! I’m cumming too~~~!”

My son releases a little bit of semen, and the battle with the last one comes to an end. My son shrinks as much as he can. It seems to be begging for mercy.

I close my eyes, comforting my son, who is in agony. It’s not just that I’m tired; I probably had sex for a lifetime.

My consciousness melts into the bed.
