Pregnancy Clinic with Yu Sieun

"It's an astonishing volume of sperm..." Yu Sieun explained, pointing at the results sheet. "This section measures semen volume, but once it fills the entire container, the metric becomes meaningless."

The paper showed 'Normal range: 1.5ml' in red text. My result read 'Over 80ml' with '(Unmeasurable)' in parentheses beside it.

"This measures sperm count per milliliter. The normal threshold is 15 or higher, yet yours sits at 2,451."

"Only 15 is considered normal? Is the sperm count usually that low?"

"The unit is in millions."

"Ah."

"You have approximately 2.4 billion sperm per milliliter."

Each figure she announced added another red underline to the sheet.

"For morphology, 4 out of 10 is normal, but here it shows 10. When fewer than 5 out of 100 sperm are abnormal, the result appears this way."

Then Yu Sieun pulled out her phone and showed it to us.

"This app displays your sperm specifications as percentages. The sample pool covers Gyeonggi Province and Seoul. As you can see, you're in the top 0%. It normally shows decimal places, but I've heard that once it exceeds four decimal points, the system simply registers it as 0%."

So I possessed the highest-grade sperm in the province. A fresh surge of pride straightened my shoulders.

"Motility, nutrient levels, and so on... This is simply..." Yu Sieun shook her head, at a loss for words. "At this level, you could likely impregnate someone with pre-ejaculate alone."

She turned to Seong Yua. "It appears the issue may lie with your wife. Would you like to undergo testing?"

"Ah, Team Leader... My wife has already been examined elsewhere. The results showed no abnormalities whatsoever."

"Pardon? Then..."

I opened the app and spoke up. "It seems the problem lies..."

"...on the other side."

"The other side?"

"Sexual intercourse."

Inside an empty, pitch-black space, only my body floated.

"Keyword search. Kim Junyoung."

A sphere labeled [Kim Junyoung] appeared, with another sphere for [Seong Yua] attached right beside it.

I connected the [Kim Junyoung] and [Seong Yua] spheres and created a new one.

The weight I felt in my hands while creating the sphere was light. That meant the burden on Yu Sieun was minimal.

'She has a constitution that accepts modifications easily. I can push the progress quickly.'

I added one more.

'That should be enough.'

I ended Modification Mode.

The scenery returned to normal and the conversation continued.

"Yes, I reached the same conclusion. The problem appears to stem from the way the two of you engage in sexual intercourse."

"What should we do?"

"Well... Our hospital operates a program called the 'Pregnancy Clinic.' Would you like to hear more about it?"

Yu Sieun smiled gently as she explained.

"Through the Pregnancy Clinic, we correct sexual technique. For reference, Stage 1 consists of regular visits for semen collection. I will personally extract Kim Junyoung's semen."

"When you say extract semen..."

I deliberately showed a hint of discomfort. The concepts I had reinforced last time would be stimulated by this.

As if she had expected this reaction, Yu Sieun spoke in a kind, professional tone to persuade me.

"There may be some sexual contact involved. However, please do not worry. I am a doctor, and this is a medical procedure. There is absolutely no need to feel embarrassed."

I smiled awkwardly and said, "Um... haha... I can handle being touched, but..."

"Yes, please continue."

"Being the only one naked... would be far too embarrassing."

Looking directly at Yu Sieun's face, I continued, "Wouldn't it be less embarrassing if you took your clothes off as well, Doctor?"

"Pardon?"

The smile that had remained on Yu Sieun's face throughout her persuasion wavered for the first time.

"You want... me to undress too?"

"Yes. Ah, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠not completely. Just the lower half, like me, should be sufficient."

Yu Sieun's expression gradually froze with bewilderment.

When things got this delicate, touching just a few strong concepts was enough. Seeing her expression, I quickly raised my voice.

"Y-You feel it's strange too, right? See! No matter how you look at it, even for an OB/GYN, touching a dick is weird! I can't do this!"

"Ah...! P-Please wait! Calm down!"

Yu Sieun seemed to regain her composure and began persuading me more actively.

"Very well. I... I will undress as well! How about that? It will feel less embarrassing then, correct?"

"...You're really going to do it?"

"Of course!"

After a bit more back-and-forth, a short while later I lay on the examination table with my lower half completely exposed.

"Huu..."

Yu Sieun hesitated for a moment, then grabbed her skirt and panties and pulled them down in one motion.

"Huu... haa..."

It was a sigh heavy with tension. Her pubic hair was neatly trimmed, as meticulously maintained as her crisp professional appearance.

Yu Sieun grasped my limp cock.

"Huu, haa, huu..."

She simply held it without moving.

"...What are you doing?"

"Eh? Ah, I-I'm sorry. Um... I suppose I should move it up and down... right?"

She began stroking.

Pat. Pat. Pat.

"..."

Shockingly, she was moving my flaccid cock up and down according to her own standards, essentially waving it toward my belly and thighs. Could that even be called stroking? 'Waving' seemed more accurate.

"By any chance... do you lack experience with men?"

"...I'm sorry."

"Ah, no. There's no need to apologize."

She seemed to be a virgin. Then why had she trimmed her pubic hair so neatly? 'Is it simply personal grooming? Even without any experience?'

I couldn't decide whether to call this professional dedication or lewd preparation.

Yu Sieun apparently hadn't noticed her mistake from our earlier conversation, as she continued awkwardly waving my cock back and forth between my navel and thighs. At this rate, I wouldn't get hard, let alone ejaculate.

'...Should I hold back?'

Suddenly, a rather good idea came to mind. I recalled the skill I had drawn after last week's session.

I had thought it was trash at the time, but it might prove surprisingly useful. For now, I clenched my pelvic floor muscles and suppressed my erection.

About ten minutes passed.

"...It doesn't seem to be working."

"Could you be suffering from erectile dysfunction?"

"...What? No, I'm perfectly healthy."

"My husband does not have erectile dysfunction."

"I-I'm sorry."

Seong Yua, who had been watching from the side, spoke up to help.

"We need to achieve an erection first before we can do anything."

"That's true. But... isn't it impossible for a man to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠become erect through willpower alone?"

"You know your stuff. Therefore, Doctor, you will need to make it stand."

Still lying down, I tapped the examination table. "Would you climb up here?"

Yu Sieun got onto the table.

"Place your head toward my lower body and your legs over here... Yes, like that."

"W-Wait! This position...!"

Her white doctor's coat draped over my head like a curtain. I grabbed her thighs as she tried to pull away.

"N-No! If we do this, everything will be... Ahh...!"

"You took your clothes off to show me in the first place. Besides, you're far too clumsy, so we need to do it this way to get me hard."

Right before my eyes, her pussy was fully exposed. If we took each other's genitals into our mouths from here, it would be a perfect sixty-nine.

Seeing such a beautiful pussy up close made my cock twitch with life.

"Look. It's getting hard."

"E-Ehh...!"

Since it had happened exactly as I said, Yu Sieun couldn't argue.

I stroked her outer labia.

"Kyaa?! W-Why are you using your hand...!"

"If I don't do at least this much, my erection will fade. It's medical contact, so it can't be helped, right?"

I answered curtly while lightly tapping her clitoris.

"Hngh...! Th-That spot..."

"I'm barely managing to stay hard right now. Please make me ejaculate quickly."

"...Understood."

Blushing, Yu Sieun hurriedly began stroking me. However, her movements were fast yet incredibly awkward; there was no way she could make me cum like this.

Normally, the innocent clumsiness of her handjob would have made me leak pre-cum, but right now I was using Ejaculation Control to completely suppress any rising urge.

"Why... why isn't it coming out...!"

"Last week, when you collected my semen, I finished in ten minutes."

"Then why now..."

"As you know, last time my wife... the team leader helped. With her mouth."

"Wh-What?!"

I had only just completed the second round of modifications. Would she accept going that far already? It was worth trying. After all, Yu Sieun had a constitution that accepted modifications well.

"With such an awkward handjob, it's impossible. You're not even producing pre-cum."

"B-But... how could I use my mouth..."

I continued stimulating the implanted concepts.

"You were the one who first suggested this as a treatment. I worked up the courage to ask as well."

"Th-That may be true... but using my mouth..."

"They say Heo Jun once sucked pus from a patient's abscess with his mouth. Are you really hesitating to simply take a cock in yours?"

"Aah..."

At that moment, Seong Yua murmured softly from the side.

"I wanted... to have a baby..."

"...!"

Yu Sieun's wriggling hips, which had been moving in embarrassment, suddenly stopped.

I had perfectly stimulated both the implanted concepts and her original professional beliefs as a doctor.

'As expected of Seong Yua.'

She wasn't called an ace at the company for nothing.

"...From now on... I will use my mouth."

Having made her resolute declaration, Yu Sieun immediately took my cock into her mouth.

"Hngh..."

"Oh..."

Just as every pussy felt new, so did every mouth. The real difference lay in the sucking technique rather than internal shape. An inexperienced, clumsy mouth-pussy like Yu Sieun's had its own special charm.

"Don't just hold it in your mouth. Try using your tongue. Purse your lips more tightly and then..."

Just like during Seong Yua's first time giving fellatio, she was simply holding it in her mouth, so I gave her instructions bit by bit.

It was the complete opposite of the Pregnancy Clinic's original purpose, but what did it matter? All I needed was to extract what I wanted.

"Mmmph, mmm, gmmph..."

Saliva flowed down my shaft in thick streams. As I played with Yu Sieun's pussy, it quickly grew ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠soaking wet, dripping honey onto my face.

My fingerwork was enhanced by various skills. If I truly focused, I could make her cum instantly, but giving her any more aversion right now would be dangerous, so I held back.

'Ah... It's been a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠while since I've enjoyed such an innocent mouth-pussy. It feels incredible...'

The mental stimulation was so intense that my cock twitched wildly. Each time it did, Yu Sieun would flinch, her pussy clenching in surprise.

After a long while, I finally activated Ejaculation Control to accelerate the urge, and the sensation of impending climax finally rose.

"I'm about to cum."

"Mmph, bff?! Hua! W-What should I do?"

Even now it was borderline. Taking it in her mouth would be too much. I was about to tell her to bring a container when—

"I will receive the semen."

The fellatio specialist had stepped in.

Seong Yua immediately took the glans into her mouth. She must have anticipated this and gathered saliva beforehand; the inside of her mouth felt as full and warm as a womb filled with amniotic fluid.

"Slurp! Gulp! Mmmgh, shluuurp!"

"Oh, ohhh, fuck...!"

She made wet, obscene sounds while using incredible tongue technique and vacuum pressure to suck on the glans. Both hands gripped my balls, massaging them with care, delicacy, and incredible variety.

Squeeze, knead, roll, massage, squeeze...

"Mmmgh, slurp! Hngh, gmmph! Mmm..."

"Khk, ugh...!"

A trickle of saliva escaped from the corner of my mouth. The dizzying pleasure made my hips buck involuntarily.

"Haa, this is insane...!"

Seong Yua's fellatio was always pure fantasy no matter how many times I experienced it. My cock swelled as if it would burst. Semen surged up from the base of my balls.

Sensing the pulsing at my urethra, Seong Yua squeezed my sack as if milking it and pulled upward with a long, firm stroke.

"Ohh, shit...! C-Cumming...! Hngh...!"

Bwooouuuuk— Bjjjuuuuk— Splurt, splurt, splurt—

"Gulp, gulp, gulp, gulp, gulp..."

The enormous volume of semen produced a continuous series of swallowing sounds. Not a single drop escaped her lips.

"Gulp, gulp, gulp... Shlup!"

"Hngh!"

Like sucking on a straw, Seong Yua drew out the last remnants from my urethra, then lifted her head while running her lips along my shaft. The sensation of being sucked from deep inside my urethra drew a stupid moan from me.

"Gulp. ...Thank you for your hard work."

That signature closing remark again.

Yu Sieun, who had witnessed a near-perfect fellatio, remained frozen in place with her mouth open and eyes wide.

I tucked my now-clean cock—glistening only with Seong Yua's saliva, with no trace of semen or love juice—back into my pants.

"Huu... We'll come again next week."

"...Pardon? Ah, yes..."

I straightened my clothes and left the examination room.
