9.

A few days had passed since I received the injection gifted by Baek Juha.

My body was visibly changing.

My height and frame grew larger, and while excess fat disappeared, my skeletal frame and muscle mass increased.

My face also became slimmer, giving off a feeling of looking slightly better than before.

'Is becoming handsome also thanks to the monster's Mana Particles?'

The contents of the injection were Mana Particles extracted from a sample of Black Cristales, a black-armored dragon monster possessing the hardest exterior and overwhelming monstrous strength even among S-rank dungeon bosses.

Gahyeon had made it a daily routine to grope all over my body—up, down, sides, and every nook and cranny.

"It's hard. It got even harder than yesterday."

More than anything, the biggest change was that my physical body itself had become hard as steel.

"Can I try hitting you once?"

"Uh, uh-huh? Gahyeon-ah? Wait a second?"

With her eyes sparkling with curiosity, Gahyeon loaded mana into her fist and swung it flat out.

Peo-eok!!!!!

"Aaa....agh...?"

"....Are you okay? Doesn't it hurt?"

"Huh...?, Why doesn't it hurt?"

"Really? It really doesn't hurt at all?!"

"Yeah! Doesn't hurt one bit!"

"I wanna hit you more!! I wanna hit you harder!!!"

"Uh... Y-Yeah!!"

"I'm really not holding back and hitting hard, okay?"

"Hit me! Give it a shot!"

Wooooong....!!!!

This time, the amount of mana was several times greater.

Peo-eoeoeoeok!!!!!

"H-How is it?"

"It doesn't... hurt though?"

Only the sound was loud; I didn't budge in the slightest.

By this point, Gahyeon seemed to be getting a bit stubborn.

"This time I'm giving it my all."

"Heheh. Go right ahead."

"A mere B-rank is laughing at an S-rank?"

Kwaaaang!!!!!!!

This time, the sound alone was different.

However, the result was the same.

"Weak~ling. It doesn't hurt at all though?"

Gahyeon's lips twitched.

"I don't know whether to get mad or be happy about this..."

"You're an S-rank, yet you can't ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠do anything, huh? Can't even beat a mere B-rank, can you?"

At those words, the sound of a string snapping in Gahyeon's head could be heard.

"Huh....? W-Wait a second. Gahyeon-ah? Why are you taking that out?"

"Seonghyun-ah, this is all for your sake."

"Even so, wouldn't a weapon be a bit too much? Huh?!"

Gahyeon squeezed out every ounce of her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠strength to draw up mana and wrap it around her twin swords.

"Here I come?"

"Wait! Wait a second!!!!"

"Iyaaaaaaaaap!!!!!!!!"

"Aaaagh...!!! Help meee...!!!!"

Kkaaaaang.....!!!!!!!!

".....!!"

".....?!"

Even from my perspective, that was definitely a strike delivered with full sincerity.

Yet, it was bounced right off.

Yeomcheonmyeolhwageom, crafted from the bones of the S-rank dungeon boss Red Breser, was pushed back, unable to overcome a mere human's forearm.

The mana wrapped around the swords dispersed as well, and the hand gripping the swords could be seen trembling as if numb.

A brief silence flowed, and our eyes met.

"W-Www-Waaaaargh!!! I won!!!"

"It worked!! You did it!! You really did it, Seonghyun-ah!!!!"

We embraced each other, jumping up and down in insane joy.

That touching moment was also short-lived.

"Eh?"

Something hot and elongated kept pressing against my belly and legs.

Wondering what it was, as I looked down.

"H-Huh?"

"Seonghyun-ah. Are you erect?"

"No...? I didn't...? Why is it like this?"

Inside my pants, a huge pillar was standing bolt upright.

I carefully slipped down the crotch of my pants.

And my underwear, too.

Then, something thick and gigantic, comparable to the holy sword Excalibur, revealed its figure.

Even after taking that unidentified arousal drug it had been amazing, but this was on an incomparable level.

And its color was also dyed a complete shade of black.

.

.

.

"Ah...♥ Ahh...♥ Ah...♥ Aaaah....♥ Ahh...♥ Ah....♥"

Gahyeon twitched her entire body while completely out of her mind.

"Get up, you bitch of a female who only knows how to mate."

Jja-ak!!!

I lightly slapped her plump butt.

"Ah-euk...."

Having been spanked so much throughout the night, both of her butt cheeks were bright red.

This time, it wasn't some kind of act, but a complete defeat-submission mating.

Because Gahyeon couldn't use her strength against me even once and had to endure being pounded just as I pleased.

Seeing her completely wrecked expression, Gahyeon looked thoroughly satisfied as well.

"Hurry up and set the breakfast table, serve me, and wash your Master, shouldn't you?"

"Yeees... Master... Just... just a moment... to rest, a bit...."

Even though I pounded her like crazy all night long without sleeping, I didn't feel tired or exhausted in the slightest.

"I told you to get up, you bitch of a female!"

"Heu-euk...!!

Chalssak!!!!

"Ah, it hurts...!! I'll get up, so please stop hitting my butt now..."

Jjaaaa-ak!!!!

"Eut-heu-eung...!!!"

Somehow or other, we got ready and headed to the dungeon.

I wanted to test my strength, but because Baek Juha said there might be side effects, I kept a low profile for the time being.

Besides, even if I didn't step in, Gahyeon's level was more than enough.

After the dungeon raid routine ended.

I had a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠short meeting with Representative-nim, and an exhausted Gahyeon went outside the dungeon first.

Having to do it all night long every day and still having to offer up her pussy even when coming to the dungeon, she looked utterly exhausted.

If there was a difference, unlike before, these days I was dragging her by force and pounding her.

I was gradually becoming addicted to the pleasure of forcibly treating a bride-to-be as a pussy slave in the dungeon...

"Seonghyun-ssi? Seonghyun-ssi! Are you listening?"

"Ah, yes."

The image of Gahyeon getting her butt spanked in the dungeon kept coming to mind.

"What did you say?"

"This is already the third time I'm asking if something is going on with Gahyeon-ssi."

"Yes. Nothing is going on, so you don't need to worry."

However, Representative-nim still wore a worried expression.

"Haa... Really, I'm a bit hesitant because it might be rude of me to ask about this kind of thing, but...."

"It's fine. Go ahead and ask."

"By any chance, are you... receiving something like blackmail? Or threats... right?"

"Threats?"

"The kind like telling you they'll treat you much better so transfer to AH Guild, or something..."

"No. There's been nothing like that at all."

"Really? For real? Swear to the heavens?"

Yoo Soyoon had already requested a meeting several times over the past few days for the exact same reason.

I understood her worried heart, but since she kept needlessly bothering me even though I repeatedly said no, annoyance was slowly welling up.

"Representative-nim."

"Yes?"

"If you call me out for the same reason next time as well, I will no longer comply."

"Ah... I understand. I'm sorry for troubling you..."

Yoo Soyoon lowered her head with a gloomy expression.

After giving my one-sided notice, while I was walking out of the dungeon, several guild members called out and stopped me.

After calling me over, they awkwardly watched my expression before one of them cautiously brought up a topic.

"Hyung, nothing's bothering you lately, right?"

'Hyung?'

It was a title I was hearing for the first time since joining this guild.

Moreover, the guy who just spoke was a magic dealer C-rank hunter named Jeong Sueon, who used to be the busiest badmouthing me. He was also the culprit who made several female guild members leave after acting like a skirt-chaser.

For a guy like that to approach so politely and respectfully was quite a fresh shock.

"Not really."

"Ah... Then that's a relief. Why did Representative-nim call Hyung over?"

I knew it.

So Yoo Soyoon is the target now.

"None of your business."

"Ah, aha. T-That's true."

Bastard.

I can see the corners of your mouth trembling.

If you're going to hide your rotting expression, at least hide it properly.

"If you don't have any business, I'm leaving."

"N-No! Wait! Just wait a second!"

"What is it? What's going on that you're acting like this?"

"Well, we wanted to ask you to get Han Gahyeon-nim's autographs for us. All of us."

"Autographs?"

"Could you, maybe? Haha."

All the guild members who came along looked at me with earnest eyes.

"I'll at least bring it up."

"Really?! For real?!"

'Like she would?'

The reason I didn't want to bring up the conversation was out of genuine concern for them.

Because Gahyeon was always itching to slaughter the guild members.

Coming out of the dungeon, I got into Gahyeon's car.

Gahyeon, who had been taking a short nap, grabbed the steering wheel with hollow eyes.

"Shall I drive?"

"No. Master. I can do it. Don't worry."

Gahyeon's form of address only changed when the two of us were alone, or when we were with Baek Juha as a group of three.

The place we arrived at earlier than expected was a jaw-droppingly magnificent house.

"What's this? Where is this?"

"Today, Eonni told us to come to her house."

"Huh? You're not coming together?"

Even though I got out of the car, Gahyeon still had her seatbelt on.

"I have some errands Eonni told me to do, so I'll be back."

Before I could even ask what it was, Gahyeon zoomed off.

'Mmm....'

While I was blankly wondering how a main gate larger than my living room would open, the rails at the bottom of the gate suddenly began to move.

When the gate opened, Baek Juha was visible, smiling brightly with her bottoms missing.

"Welcome, Master. My eyes almost popped out from waiting."

"Why aren't you wearing pants?"

Baek Juha, wearing only a white lab coat, had her private parts completely exposed in plain view.

"Oh, Master, really. Isn't it about time you addressed me comfortably?"

"Mmm... C-Can I really do, do that...?"

"Of course, Master♥"

Baek Juha clung right beside me like a vixen, grabbed my hand, and had me squeeze her luscious butt as is. Just like lovers or a married couple,

In that very posture, we walked across the vast yard for quite a while before arriving at the building.

"Please channel Master's mana into this place."

When I channeled mana into the device Baek Juha pointed at, the red light turned green, and the door clanked open.

"I changed the settings so that the door opens when Master's Mana Particles are inserted."

Coming inside the house, she hugged me tightly and added.

"Now, this house is practically Master's house. Whenever and anytime you want, please come and pamper me to your heart's content, okay? Fuhut."

Jjo-o-ok...♥ Jjo-ok♥

Baek Juha's kiss was a level more voluptuous, a mature flavor compared to Gahyeon's.

"Why did you call..., call me to your house today?"

"For the last remaining test, while getting the results takes a full day, the test itself finishes quickly. So, in the leftover time, I wanted to do plenty of what I've been holding back...♥ you know? Gahyeon happens to be busy, too."

For the past few days, I had undergone examinations daily in Baek Juha's private office at the AH Magic Research Institute.

Because the tests regarding the Mana Particles I received took quite some time, I hadn't been able to mate with Baek Juha even once yet.

As if she was quite dissatisfied with only enjoying brief foreplay, she seemed completely determined today.

"The test we are doing today is a Mana Circuit test. It's a test to see how many types of Mana Particles Master's Mana Circuit can accommodate."

The test didn't take as long as expected.

No, it ended far too quickly.

About 10 minutes? 15 minutes?

During that time, entering a huge capsule and waiting was all there was to it.

As soon as the capsule opened, Baek Juha ran over and embraced me.

Interlocking her fingers with mine.

A dense kiss that felt like whispering sticky love.

Jjo-o-ok...♥ Jjo-o-ok...♥ Jjo-ok...♥ Jjo-o-ok...♥

Lips pressed against lips without a gap.

The communion of tongues taking place within.

Exploring the inside of each other's mouths, we gradually began to burn with passion.

I groped and squeezed the huge breasts that seemed ready to burst through her white lab coat this way and that.

Then, suddenly.

A question I had harbored in my heart surfaced.

It was the relationship between An Hyeonwoo and Gahyeon.

I had felt it when An Hyeonwoo came looking for us a few days ago.

Gahyeon was one thing, but An Hyeonwoo, who left the woman he was supposed to marry with another man and departed, didn't seem normal either.

Seeing how fairly tight-knit her relationship with Gahyeon had been over the past few days, perhaps Baek Juha knew.

Paa♥♥

Taking the chance as a breathless Baek Juha pulled her lips away, I brought it up.

"Baek Juha.... No, Juha-ya."

"Yes...? Master...♥ Why did you call me...? So gently...♥ and lovingly...♥♥"

"There's something I'm curious about."

Noticing my quite serious tone, Baek Juha straightened her demeanor.

"If it's something I know, I will answer anything, Master."

"By any chance, can you tell me what kind of relationship An Hyeonwoo and Gahyeon have?"

"When you say relationship, what kind of..."

"There was a time when An Hyeonwoo came to see us."

In a split second, Baek Juha's expression stiffened slightly before relaxing again.

"Their relationship was so strange back then, so I was asking to see if you knew anything. I've also been curious ever since Gahyeon moved into my house to live with me."

A brief silence flowed.

Baek Juha, wearing a somewhat bitter expression, opened her mouth with difficulty.

"Because Master is special—no. Because it's a story Master must know someday as well. It can't be helped, then."

Baek Juha let out a small sigh and sat down on the edge of the bed.

"Would you like to listen to the story held in my embrace? Because it's a bit—no, quite a heavy story."

'Is she deliberately shaking her breasts even more vulgarly because it's heavy?'

In any case, it wasn't a bad thing.

Drawn by her maternal instinct, I opened both arms, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠and she softly enveloped me with her warm breasts.

And then, she began a long story.
