Vol 1 Chapter 3 – The Doctor and the Younger Sister

A few days after Yukina’s… proposal? I was summoned by my doctor and found myself in an examination room inside the hospital.

“Yuuma Kisaragi-kun… about you…”

“Yes…?”

The doctor explained things to me while showing me a paper with my test results.

It described the abnormalities in my body.

“Your sperm is abnormally active. The concentration is nearly one hundred times the normal value. This is clearly an anomaly… Could it be, Kisaragi-kun… that you’re going to get hard just looking at me?”

I swallowed hard as I looked at the female doctor in the white coat before me.

She was about 160 cm tall, with a stunning figure. With her long hair and well-defined features, the word “beautiful” suited her perfectly.

Her chest was also extremely large.

Honestly, she’s my type.

And now, this very woman was crossing her legs seductively and staring right at me. It would be stranger not to react.

I glanced down at my lower body.

Sure enough, a certain part of my pants was bulging.

I scrambled to hide it, but it was too late.

A bewitching smile played on the doctor’s lips.

I hung my head, embarrassed.

“Just as I thought… Your body is like that of a man from three hundred years ago. To put it simply, you’re in the throes of puberty. That’s why your sexual desire for the opposite sex is heightened. And as a result, your semen has become abnormally active.”

A man from three hundred years ago, huh…

It seems I haven’t just come to a world with flipped gender roles…

As I was thinking this, my expression must have turned grim.

Seeing my state, the doctor’s face filled with concern.

Then, she placed her hand on my forehead.

Her hand was cool and felt wonderful.

Maybe that was why.

My heart began to pound violently.

ba-dump, ba-dump

“Are you all right? You don’t have a fever, do you?”

My face flushed red and I froze solid.

The doctor peered into my face and tilted her head.

God, she’s so alluring… Is this the charm of a mature woman…?

The deep cleavage peeking out from under her white coat was captivating.

On top of that, she was peering up at me from under her lashes.

For someone like me, who had zero romantic experience in my past life, this was too much stimulation.

My self-control was about to crumble.

So, I decided to look away.

But that was a mistake.

I averted my gaze downward, and my eyes fell on what was there.

It was the doctor’s beautiful legs, wrapped in stockings.

In that instant, she grabbed my right hand and made me touch her thigh through the stocking.

It was soft and incredibly warm.

“Fufu, how cute~. Are you getting turned on by me? If you like this body so much, I’ll let you touch it as much as you want.”

The doctor said it with a playful laugh.

“St-Stop it. This is sexual harassment, isn’t it!?”

In this world, it should be sexual harassment when a woman touches a man’s body.

I used what little self-control I had left to push her hand away.

“Oh? I’m sorry. But what am I supposed to do? I can’t hold back when there’s such an attractive man in front of me.”

“Wh-What…?”

“And my, your ‘thing’ really is quite large…”

As she said that, the doctor touched my swollen lower half in a lewd way.

At that moment, a thrill shot through me.

A jolt ran through my body, and I nearly fell out of my chair.

Seeing my reaction, the doctor let out a little laugh.

She’s completely toying with me…

Overcome with shame, I stood up to flee the room.

But the doctor pushed down on my shoulders, forcing me to sit again.

As if to say, You’re not getting away this time, she sat on my lap and hugged me.

Then, she brought her lips to my ear.

Her sweet breath washed over me.

My body temperature was skyrocketing.

This is it… I can’t take any more.

I struggled, trying to break free with all my strength.

But I was no match for her.

The doctor wouldn’t let go. In fact, she pressed herself even closer.

The feeling of her soft breasts made me even more aroused.

“H-Hey!? Let go of me!”

“I won’t. Because, as your doctor, I’m about to treat your little problem down there. Now, be a good boy!”

“W-Wait, where are you touching!?”

“What do you mean? I’m treating this right here. Just leave it to me. I’ll be done in a flash!”

“No, wait!? Not there, anywhere but there!?”

“It’s okay! I’ll be gentle!”

“Noooooo!!”

— After that, I was treated very, very thoroughly.

“Ehehe~♪ Dearest Onii-sama♡”

“Y-Yukina… could you let go of me?”

“No! I’m going to take a bath now, so let’s get in together.”

Yukina started trying to pull my clothes off.

I was desperately trying to stop her.

We were in the changing room of the large bathhouse located inside the hospital.

Why is there a bathhouse in a hospital? you might be wondering.

Apparently, only super-VIPs like the wealthy, politicians, and their families are allowed to be admitted to this hospital.

Which means it’s strange for a commoner like me to be here… but it seems there’s a bit of a story behind that…

Well, putting that aside for now.

I was currently in the process of being assaulted by Yukina yet again.

I tried to peel her off me somehow, but she was too strong.

Why are the women in this world so powerful?

It looks like I have way more muscle mass…

As for why I was in this situation, it all happened after I was finished being “treated” by the doctor in the examination room.

In the end, I was milked dry until my “son” was completely cured.

And after my little problem was fully resolved, the doctor told me about this large bathhouse as she was leaving.

Just as I was about to go in, Yukina appeared out of nowhere, which brings us to the present.

“So please, could you let me go? This is just too embarrassing…”

“Fine… Then I’ll wash your back for you. After that, it won’t be a problem, right? Let’s go.”

“Hey, is ignoring what I say your default setting?”

“Come, come, hurry up. We’re running out of time!”

Without a shred of hesitation, Yukina began to take off her clothes.

I quickly looked away.

But I still caught a glimpse of her naked body.

Yukina had an amazing figure. Her breasts were large and perfectly shaped.

Her waist was cinched tight, her hips were small, and her legs were long and slender.

Honestly, it was incredibly erotic.

My self-control was on the verge of exploding.

But I couldn’t lose here.

I grit my teeth and focused on maintaining my composure.

Then, as if she’d seen my reaction, Yukina approached with a bewitching smile. She grabbed my hand and pressed it against her chest.

A soft sensation spread through my palm.

My mind went blank, and my thoughts came to a halt.

Seeing me like this, Yukina pressed my hand even harder.

Then, she brought her face close to mine and stole my lips.

*Mmph… schlick… mwah… ahh…*

I was kissed, completely at her mercy.

A few seconds later, I was finally released.

A silver thread connected our lips.

I was in a daze.

Seeing my state, Yukina smiled again.

“Shall we go? Dearest Onii-sama…♡”

“Ah, yeah…”

And so, I was completely and utterly defeated by the doctor and Yukina.
