Chapter 288 – Semen Collection

Even after we talked about our homework, we would hold each other close to each other and talk about this and that, then take a shower before going to bed and sleep in the same bed.

The next morning that came like that.

The first thing that caught my eye as soon as I got up from bed was Hwayoung senior, who seemed to have already finished her morning grooming.

“Woke up?”

“It’s early in the morning.”

“If I’m in good shape, I usually get up around 6 in the morning. The sunlight and air in the morning are the best for replenishing mana. In the days when tar cigarettes ran out, I was not in very good condition, so it spread every day.”

Is that why Cha Yu-ri, who consistently wakes up every morning, has a lot of magic attribute?

As a latecomer, in order to catch up with the two of them, I also need to try the lifestyle of waking up a little earlier.

“Clothes… You are all dressed.”

“Why are you sorry?”

“A little bit.”

Even if I didn’t have time to go out after having sex one more time, I wanted to see the senior’s breasts one more time.

There seemed to be no bugs caught by birds that didn’t wake up early. You must wake up early next time.

“Senior, do you have a schedule for today?”

“Me? I need to go home and make potions. I have to work diligently for a while to meet the due date. Yesterday too, I took a little bit of time.”

“Why don’t you do it in advance.”

“You did this because you were disturbed by your semen study. So why don’t you tell me that sperm concentration can be controlled…”

Senior Hwayoung, who had been muttering so, rubbed her own belly lightly and muttered in a slightly suspicious voice.

“… When I packed it inside yesterday, it wasn’t cheap with ‘something’ just in case… ?”

“He’s a guy with that level of reasoning. I don’t think I would have begged irresponsibly without seeking consent from my seniors.”

“… Until now, they didn’t even explain properly and packed everything inside.”

“Of course, at that time, everything was set at 0% and cheap. And if it’s the contraceptive pill for you, you don’t have to worry about getting pregnant in the first place.”

“It is.”

One day, if the time comes when the senior wants my child, she will do it without hesitation and raise the sperm concentration to the maximum level to cum inside her.

Apparently, neither I nor my seniors had plans for a second generation, so it was right to restrain ourselves for now.

… On top of that, having children with anyone would be such a big deal that you would have to discuss it with other women as well.

“Anyway, as much as you said, I won’t take birth control pills from now on either. So be careful not to suddenly become wrapped up in ‘what’s in me’.”

“I was still like that.”

“… And, sit there for a while before you get dressed.”

“Yes?”

“It’s okay, hurry up.”

I wanted to say something. As she said, I quietly sat on the edge of her bed, and Hwayoung knelt down on her knees and quietly pushed her face between my groin.

“This time, wrap it with ‘what you have’. I will study properly once again.”

Come to think of it, you asked for semen with sperm for research purposes.

As promised, senior Hwayoung, who was diligently trying to get her into fellatio, was proud of me in many ways.

“If ‘there is’, what concentration do you mean?”

“… What?”

“Sperm concentration. You said you could control it.”

“… Can that be controlled?”

“Is it okay?”

“How many percent can it be adjusted?”

“First of all, it is said to be 50% as a figure in the function.”

“Crazy. Are you really human?”

As soon as she heard my words, she reacted with shock and swear words.

“Junior, do you know what percentage of sperm in the semen of a typical male is?”

“Well. I’m not sure, but maybe 10 to 20 percent?”

“It’s around 1%.”

“… Yes?”

“Generally, the percentage of sperm in semen is around 1%. Did you understand?”

… Something, quite different from what I expected.

It was only after hearing her sincere explanation that I realized once again how absurd this ‘sperm concentration control function’ I had was.

Wait, then how does the gauge value of the ‘sperm concentration control function’ that I am using change?

“To explain the function, the gauge value of the sperm concentration control function does not move in direct proportion to the value. 1, 2, 3, 4, 5%, starting with the smallest number of 0%. Then, it can be changed in eleven stages of 10, 20, 30, 40, and 50%.”

‘Why are you telling me that important thing now?’

「When the owner first used the function, I was still ‘before being purchased’ by the owner.」

‘… Okay.’

Certainly, this part also had my problem of just pulling the gauge to the left without checking it properly beforehand.

Of course, I thought the number would change in direct proportion, so I thought the third column was 10%.

It was the moment I first learned from the words of my senior that the third column where the gauge was initially located meant 2%.

“Do you understand now? What do you mean by that 50%?”

“… I’m sure you know. That’s also why the seniors reacted like that.”

“First of all, never tell anyone about that function. If other researchers heard it, not me, it must be a human experiment subject.”

“… All right.”

Even if it wasn’t that, I was fully aware that the existence itself was an experimental research subject.

Male awakener. Colorless history. And to this I found out today.

It was a moment when I was reminded once again that I was a foreign being in this world in many ways.

Maybe it’s because I’m a reincarnated person with memories from another world.

It was still an unknown part to me, so it was meaningless to question it.

“Anyway, I’ll think about that later. Right now, you need my semen to use for research, right?”

“… It doesn’t.”

“If you’re going to use it for research, wouldn’t it be much more useful if it was 50%?”

“… No, stop that. It’s clearly a level of concentration that’s out of the human range. Perhaps the aftermath will hit your body as well.”

“An aftershock?”

“Imagine that you ejaculate 50 times in a row right here. Can you stand it?”

“… It would be nice if it ended up being taken to the emergency room.”

It wouldn’t be strange if she actually became a mummy instead of figuratively. After hearing the realistic analogy, I feel bloody for nothing.

“Of course, I don’t know if that much of a burden will actually be given, but it’s good to increase it little by little and check whether there is a risk or not.”

“… Well, there’s nothing wrong with hearing what the seniors say. After all, you must know the wisdom of living in the world much better as you have lived longer, don’t you?”

“Good idea.”

Hwayoung senior, who dismissed her story about her 50% semen, pondered for a while, then carefully pushed three of her fingers in.

“For now, this much.”

“30%?”

“It’s 3%. 30% or 50% is the same as being far out of the human category. Did you really listen to me?”

“It was just a joke. But according to what you said, isn’t even 3% out of the human category?”

“… She just decided on her own that this would be fine. Assuming that every 1% increase in sperm concentration puts the burden of one ejaculation on the body, 3% is three times, so I thought you would be able to endure it.”

“Is that based on the fact that I ejaculated five times at my senior’s house the other day and went back?”

“Huh. If you feel like this is too much of a burden, it doesn’t matter if it’s 1% or 2%.”

“No, let’s do it at 3%.”

If 3%… There won’t be any problems whatsoever.

Considering that my basic number was 2% in the first place, 3% was about 1.5 times the burden, not three times.

And I had the experience of being cheap up to four times in a row before this sperm concentration control function came into being.

『0%—-●——–50%』

I pulled the gauge three steps and set it to 3% for the senior who approached me with an empty potion bottle.

“… You know, junior.”

“Yes.”

“Couldn’t you tell me in advance at the moment when you are about to ejaculate? Right before I come out, I’ll be putting this on my junior’s stuff, so if you wrap it…”

“Senior, I clearly said that I would only offer fellatio. And I think fellatio should be finished with ejaculation in the mouth.”

“… Cowardly, for real.”

If I didn’t do this, I was thinking of pulling out 1 liter at a time.

Sensing that her own proposal didn’t work, her senior, despite her grunts, gently opened her mouth and covered the front of her cock with her lips.

“Yes.”

Her little mouth full of my cock, eagerly moving her mouth and tongue.

It was an impression I had heard before, but there really was no word that could describe her better than ‘a hamster biting a banana’.

It was originally cute, but the senpai who became especially cuter began to bite my cock and start fellatio.

Little bit little bit

“Um, um…”

Peck, peck

“Huh, yup, um…”

The senpai’s tongue movements, which filled my cock in the cheek pockets, instantly soaked my cock with warm bodily fluids.

To solve morning erections with senior Hwayoung’s fellatio. In many ways, it’s really the end of extravagance.

In addition to that, the senior also seemed to be quite good at fellatio, probably because he had already sucked my cock three times.

I licked my tongue under her glans and felt the sensation of my cock.

Knowing how to use your tongue boldly was a move that confirmed that the beginner’s fellatio had already graduated.

In particular, seeing that he focused on the glans rather than the pillar, the man clearly knew exactly where he felt the stimulation.

A few minutes from the moment I started to feel the soft cheeks and soft tongue.

Her cock, which was still erect from her morning period, quickly filled her mouth with the desire to release the semen.

“I’ll eat it, senior!”

“Huh!”

As soon as I said I was going to cum, she panicked and tried to pull her face back for a moment, but I reflexively grabbed the back of her head and pulled her closer to me.

I vomited the semen that had accumulated all night into the senior’s mouth, which filled one cheek with my cock.

“Fubuuuuu… !!”

There was still a senior tapping on my thighs in agony as if I wasn’t used to the taste, but a promise is still a promise.

After squeezing out all the remaining drops of semen from her cock, I freed my cock from the back of Moon Hwa-young’s head.

“Thank you for your hard work, sun…”

“Fuuuuu… ! Hevehehe…”

“…”

“Ugh, ugh… Hey, it looks like there are tadpoles crawling inside her mouth… Bhehehe…”

… Seeing the senior spit out the semen collected in her mouth into the potion bottle while her tears welled up, it seemed like he would develop a strange taste for nothing.

I’m sure you’ll get angry if I say this, but I inadvertently entered into my head that it would be nice if this research didn’t work out.

So next time we meet, he’ll give me a blowjob to get my semen.
