For Sale. Fallen Lady. Never Used.

Crack.

Was it because we were underwater? Carla’s insides felt much clearer than usual.

No, was I supposed to endure this?

How?

Though the lack of lubricant might make rough movements painful for both of us, moving gently seemed like it would feel better than ever before.

However, unaware of my feelings, Carla briefly frowned, then soon flashed an open smile.

“Wow… doing it underwater makes it feel tight, just like the first time with Master.”

“It wasn’t a pleasant memory for you, was it?”

“Ah, it wasn’t that bad. Of course, I prefer the gentler Master now over the forceful one back then… but still, Master did fulfill my request.”

“Request?”

What did I do?

Even with my exceptional memory, all I could recall was Carla whimpering in fear and me giving orders.

Ah, and that ridiculous dad joke, too.

…Could the library be the root of all evil?

Trying to divert my thoughts, it seemed even that wasn’t allowed.

Carla puffed her cheeks slightly and spoke in a sulking tone.

“Before we started properly, I asked for a kiss. I was really touched when Master granted it… but to think Master forgot…”

“I do remember it, of course… I was going to do it anyway, so I wondered if it even needed to be requested.”

“You were planning to anyway?! Wow…”

Carla’s face suddenly relaxed into a daze.

She looked like someone who had grasped all the happiness in the world with an expression of clumsy contentment.

“…What? Is there some other meaning to a kiss besides expressing affection?”

Not just Carla, but Elisha, Iris, and Faye had also begged for kisses.

Wondering if there was something more to it, I tilted my head, and Carla did the same.

“Expression of affection is everything. But it’s not something you do with just anyone, right? It’s kind of a vow.”

“Ah.”

Now that I think about it, this is a fantasy world set in medieval times.

The meaning of a kiss being much heavier than it was in modern times wouldn’t be strange.

No, more precisely, the weight lay in the vow.

In a world where honor was paramount, a vow was a promise that staked one’s social standing.

Now I understand their eagerness for kisses.

This isn’t just a fling, right? You’ll cherish me in the future, too, won’t you? It must have been their roundabout way of asking.

Suddenly, I remembered the vow Carla made by kissing me in the dungeon of Gef City, and I felt unexpectedly emotional.

“Carla, do you want to kiss?”

“…? Yes!”

Though not entirely sure, Carla smiled brightly and nodded.

Squish.

Naturally, Carla’s ample chest pressed against my upper body and flattened.

This soft yet resilient sensation always sharpened my senses, but…

Now, there was something more pressing.

Chu.

The ticklishness of our lips touching, the ticklishness created by our breaths, and the resonance of the word “vow” we had discussed earlier.

Who knew such an ordinary kiss could make my heart flutter this much?

Surely, we’ve done it numerous times before, but today, I seem to be overly sensitive.

“Ah! Master’s face turned red! How cute!”

“Hmm. Let’s leave this topic and continue with the Resonance training discussion.”

“Right! I almost forgot. Did I explain why we’re doing it in this posture?”

“No, you didn’t explain why we have to endure moving and climaxing in this state.”

“Then I’ll tell you now! Remember when I said that magicians with the same core can synchronize their magical wavelengths and share magical sensations?”

“Of course. I learned to cast magic through you when I was learning basic magic. But this was useless for Resonance, right?”

Basic magic was just about causing phenomena, so it didn’t matter.

But from low-level magic onwards, one must imagine a clear goal, making it impossible to replicate with borrowed sensations alone.

Especially not the secrets of the Lindelheit family, known as a magic nobility.

Carla, knowing this better than anyone, grinned.

“Today will be a bit different. Instead of me synchronizing with you, you’ll need to synchronize with me.”

“Eh? How’s that different?”

“It is very different. First, matching magical wavelengths to synchronize is inherently related to Resonance.”

“So, it’s not just about sharing the sensation of manipulating magic but also knowing how to match it?”

Thinking about it, it made sense.

Learning magic through Carla’s synchronization was like being spoon-fed.

But eating and cooking were different things, weren’t they?

“…But do we have to do it while inserted like this?”

“Unless you are a mid-level magician. As a low-level magician, to feel and replicate another person’s mana pattern, you have to become one as much as possible.”

“Indeed. If I could do it like Carla, I would have mastered Resonance long ago and even reached mid-level magician status by now.”

In fact, thanks to Carla’s tutoring and system tricks, I was getting stronger much faster than during my H&A days.

Still, I haven’t reached mid-level magician status yet.

As I nodded, Carla added seriously.

“But don’t focus too much on the mana. If you do, your penis will become flaccid and fall out.”

“…You said we can’t move or climax, right?”

“Yes. Then I can’t hold on, and my mana will scatter.”

“So what should I do?!”

Crying out in disbelief, Carla’s lips curled up.

“I have a plan! Since we’re keeping the core close to make it easier for you to feel…”

Squish.

This time, it wasn’t just her soft chest pressing against my body, but she also hugged me tightly enough to hurt a bit.

Right. Faintly, I could feel Carla’s heartbeat transmitted to me as clearly as if it were my own.

“How about now? It won’t slip out, right?”

“Rather, I should be worried about my self-control.”

Perhaps pleased with my somewhat disgruntled answer, Carla smiled lightly and brought her lips close to my ear.

“Let’s start then. First, close your eyes and concentrate on the beat of my heart, Master.”

“Okay.”

I followed Carla’s instructions, closing my eyes and honing my senses.

The sound of water manipulated by Elisha nearby.

Droplets of water falling somewhere.

And Carla’s faint breathing.

As I concentrated, the sounds gradually faded away.

What initially seemed difficult had become a natural, meditation-like focus as I learned magic.

Less than a minute after closing my eyes, the only sound I could hear was my own heart beating.

Thump, thump.

My heart pulsated vigorously as usual, with the mana core rotating in sync with its rhythm.

However, the sensation from my lower body inside her and the increasingly firm touch of her nipples against my chest also began to make their presence known.

I inadvertently started counting the ridges inside her instead of following the heartbeat.

Carla, somehow noticing my diverted attention, whispered again.

“I’ll let you play with it as much as you want later, so please focus here for now.”

Groan.

A tingling sensation in my chest, as if in protest, made mana burst forth.

Somehow, I managed to refocus and began to concentrate once more.

Deeper and deeper. Sinking into a swamp, losing myself in it. Downward, further down.

Until I reached the very bottom, where even the sound of my own heart could no longer be heard.

A feeling of complete emptiness, as if in a dark room with no windows, blindfolded.

At the end of my inner precipice, there was nothing.

Or perhaps, with my current state, I was incapable of sensing anything.

Floundering in the water, I started to desperately search around.

Hoping to find even the slightest stimulation.

How long had I been doing this?

Thump.

A faint vibration was coming from somewhere.

It definitely wasn’t coming from within me. My heart and my core didn’t beat like this.

Thump, thump.

But the more I focused, the clearer the sensation became.

Instinctively, I realized what it was. This wasn’t mine; it was Carla’s heart and core.

Our chests touched, and our lower abdomens connected.

Though we were originally two separate beings, at least for now, Carla and I have become one.

Perhaps that was why.

Even though I was concentrating on my inner self, the deeper I went, the closer I felt to Carla’s core.

No, I was actually getting closer.

The sound of the heartbeat grew louder, and the intensity of the core’s brilliance increased.

Unknowingly, I let out a sigh of admiration when it seemed within reach.

Unlike my core, which merely circulated around my heart, Carla’s core was on a completely different level in terms of the number of rings, size, and even the way it rotated.

Only a strange sense of kinship allowed me to guess that we were using the same breathing technique to create our cores.

For a moment, I was lost in front of Carla’s core.

Then, Carla’s gentle whisper guided me to the next step.

“You’ve done well. Now, imagine overlaying your core on mine. Despite the differences in size, the number of rings, and the way it rotates, try to overlay them.”

…Could I?

Until now, I’ve followed along well, but from here, I felt uncertain.

But I had to at least try.

While focusing on Carla’s core, I slowly brought my own core, which I had momentarily forgotten, to the surface.

The emerging location was naturally where Carla’s core was.

Of course, it wasn’t that my core and Carla’s core were actually overlapping, but rather the image of it.

Thump, thump.

Thump, thump.

Our heartbeats were slightly out of sync, like a missed beat. I needed to synchronize them.

Controlling one’s heartbeat on demand was nonsense.

But I had already hinted at it.

Essentially, it was like turning on and off the Blessing of the Sea.

Both the heartbeat and the mana wavelength were merely secondary changes that followed.

The important thing was to integrate my core with Carla’s core.

Although it seemed the system correction didn’t apply to pure mana manipulation…

At this level, I should be able to manage somehow with my current abilities.

As naturally as moving my arm, I began to synchronize my core with Carla’s.

Noise, resistance, cancellation, distortion, etc.

There were a few trials and errors, but somehow, it worked, thanks to my knowing the trick.

Thump, thump.

Our heartbeats sounded unified. Simultaneously, a rapid expansion of perception occurred.

It must be a phenomenon caused by sharing Carla’s mana sense.

…However, this didn’t last long.

I reflexively pushed Carla away as my concentration broke.

“Why is it that not only our magical senses but also our physical senses are shared?!”

“So, the sensation of my vagina that Master feels is… like this…?”

I didn’t want to know the sensation of being inside her right now!
