"Well, still… that was quite a lot…"
I muttered to myself as I held the heavy container in my hand.
In exchange for postponing various procedures in a way that benefited us, they demanded that we hand over the goods first. We also wanted to conduct checks for diseases and other issues, so it was definitely preferable for us to extract it beforehand.
Ideally, I would have had Misago handle it, but after reaching climax from just a kiss earlier, she turned out to be completely useless and never came back.
"Well, can't blame her. The girl's still a virgin."
Being the youngest of our generation, she never had the opportunity for such experiences. Given her age and her vivid imagination, her pent-up sexual desires probably made her perceive the real thing as something even greater than it actually was.
If the reality was worse than expected, the disappointment would be severe, but that Hisui turned out to be a jackpot. From what I could see, he exceeded all her expectations and fantasies.
"Having too much experience is a double-edged sword, though."
If there was a previous man, or if there was any sense of being cuckolded, it would initially trigger an intense burst, but afterward, it could lead to distancing, disillusionment, or even erectile dysfunction (ED). The side effects weren't exactly desirable, so it wasn't something I'd recommend.
"You have to be as extreme as I am, right?"
Since I was the most experienced among us and the only one who could handle it in that situation, I simply followed the flow and drained him completely.
By the way, when I extracted this much from Grandpa back in the day, he got mad and asked if I was trying to kill him. It was a fond memory.
That time, Grandpa couldn't stand on his feet for about two days.
On a related note, when I tasted what was left in the cleaning process, it was thick and rich—excellent quality. If he can produce this three times a day, there's no way his rank would be B or C. At the very least, he's an A, possibly even S-class. At that level, just producing it would be enough to live comfortably off the subsidy—what they call a "purchase price."
Honestly, that guy, Hisui, probably just had the misfortune of being born in the wrong place. If left to his own devices, he could survive just fine.
Whether we can tie him down or not will depend on Misago's skills.
"Quite the heavy responsibility, huh?"
I chuckled to myself as I walked along in a good mood.
"Grandmother?! Where have you been?!"
While lost in thought, Tsugumi appeared.
"Perfect timing. Here."
I casually tossed the sealed container I had just extracted into the air towards her.
By the way, this thing is generally used as an extraction device, but the lotion-like liquid inside is an artificial seminal plasma—basically, a synthetic version of the non-sperm components of semen, recreated with saline solution to efficiently extract and preserve sperm. It can be stored in this state for about a full day.
Of course, adding saliva or bodily fluids would introduce digestive enzymes, bacteria, and foreign immune cells, rendering the sample useless. So, preparing with the mouth—whether upper or lower—would ruin everything. Naturally, extracting or spitting it out from either mouth is also not recommended.
"Eh? W-Wah?!"
Tsugumi fumbled with it as she tried to catch it.
Because of its unique elasticity, it bounced around wildly.
"That's the, uh, stuff I extracted from Hisui, the guy Misago brought in. Just send it to the hospital under my name, and they should understand. I'm counting on you."
Tsugumi had a puzzled expression, as if struggling to process what I just said.
Before she could react, I tried to slip past her.
But—grab.
I was caught.
"What do you mean by that?"
Tsugumi's eyes were bloodshot.
She cradled the extraction device carefully in one arm while gripping the back of my neck with her other hand.
"Exactly what it sounds like. It's fresh, straight-from-the-source, thick white essence from Hisui. If you don't hurry and deliver it, the rank will drop."
Her gaze darted around in confusion.
"The artificial seminal plasma has stabilizers in it, so a little delay won't matter!"
Her comeback was quick.
"Tch, you already knew, huh?"
Grandpa had also used this method in his later years since direct extraction became too taxing, so it wasn't surprising that she was aware.
A woman like her wouldn't be caught off guard by a visiting male.
"Was everything okay?!"
She was likely concerned about whether we had treated the guest respectfully, or how things had gone in terms of male hospitality.
"From what I could tell, he was quite pleased. Even thanked me."
"No way…"
By the way, under normal circumstances, extracting that much from an average male would leave him unable to stand the next day—if not outright filing a complaint about a near-death experience.
In this case, we both enjoyed ourselves, so it worked out fine. It's all about finding the right rhythm with your partner.
For reference, the average male these days has a sex drive that requires release roughly once every three days. Producing three times a day is already way outside the norm.
"That Hisui… he's a good man. Just like Grandpa was."
I didn't survive this long in the hospitality business out of sheer luck—I have an eye for people.
"Like Grandfather?"
A short, simple explanation was all she needed.
"Tsugumi, I'm pretty sure you'd be able to handle him just fine. You should try pushing him a little later."
They were probably around the same age. She was good-looking, too, so it'd be a waste otherwise.
"Hyahhahaha!"
Tsugumi's face turned bright red, and she completely froze up, overloaded by all the information.
With that, I finally withdrew to my room. Interacting with young people is fun, but exhausting.
Time for a nap.
Author's note :On the Concept of Cuckoldry and Sexual Competition
The idea of "cuckold-induced ejaculation" stems from biological competition.
For example, chimpanzees, which live in promiscuous social structures, are constantly in a state of being cuckolded. Their evolutionary strategy compensates for this by developing large testicles, roughly the size of golf balls, to maximize sperm competition.
In contrast, gorillas, which enforce strict mating monopolies, have much smaller testicles—about the size of ginkgo nuts.
By the way, I personally hate NTR (Netorare, or cuckoldry), so rest assured, this story is NTR-free. While the protagonist may "steal" partners, he will not be the one getting cuckolded. There will be some degree of harem elements, but everything is centered around the male protagonist.
As for semen preservation, under normal conditions, sperm can survive for about a day as long as it isn't exposed to extreme heat, cold, or dryness. However, in this world, they're even more fragile.
Also, mixing semen with anything other than vaginal secretions will kill the sperm. So, using generic lubricants is a bad idea.
For reference, artificial seminal plasma is commonly used in fish artificial insemination—it helps extend sperm lifespan and improves fertilization efficiency.
