The night I spent with Karlia was one of the most memorable of my life.
It was amazing beyond description. All my pent-up tension was released, and I became a brand new man once everything was over.
According to her, I passed out after doing it four times.
"Is that a lot?" I asked her.
"No. Pretty average."
As someone who had spent so much time with many men, Karlia probably thought I wasn't anything special.
It hurt my pride a little, but I had gotten what I wanted.
The research ended with the results I already expected.
Her Original Magic didn't work on me.
She said it was the same for her.
Neither of us became stronger thanks to the sex. With that out of the way, there was no longer any need for sexual relations.
The problem with memorable incidents, though, is that one often tended to think about them a lot.
And so, barely a week after my first time with Karlia—or with anyone for that matter—I was back in her room.
"What is it now, Lewis?"
It was shameless of me, but... I was beyond redemption at that point. My thoughts and body had sunk into depravity.
Was it love? Not really.
It was simply uncontrollable lust. This immense emotion forced me to go further into something I had initially wholeheartedly avoided.
"W-we can't be sure it's a failure!"
"What?"
"Your Original Magic! Let's try it again. It's too early to judge its effects."
"Lewis, my Original Magic's effects are instant."
"Ngh!"
She wasn't wrong. However... I couldn't accept that at this point.
"J-just cus it hasn't happened before doesn't make it less of a possibility!"
"Lewis..."
"I'm an Inept, right? An exception! Maybe it takes longer. Who knows if—"
"If you want to fvck me, just say it straight!"
I instantly fell silent.
"Jeez..." Her exasperated voice was filled with disinterest as she looked away.
Her words surprised me, making my timid self realize just how roundabout and selfish I had been.
No, I probably realized that a while back. I just didn't have the resolve to go beyond what was convenient for me.
Based on her stance, Karlia wasn't going to budge unless I fulfilled her condition.
She was right, though. I truly wanted to fvck her.
"... F-fvck..."
"What was that?" Her voice echoed in my ears as I stuttered with my speech.
Everything was at stake. And, even though I had thrown away my pride many times to get what I wanted, doing this was extremely difficult.
However, no pain, no gain!
"P-please let me fvck you!!!"
I was surprised by my earnest and desperate words. They were loud, and echoed throughout the room.
Silence filled the area and I returned to my senses.
'Shit... what have I... what did I just say?!'
My body shivered even more as I felt the uncomfortable decorum reach a climax.
However...
"Kekeke."
... I found out my worries were not necessary.
"Finally. You've finally said it, haven't you?"
Karlia looked happy, and then she stared at me with her seductive eyes, stripping me down with every gaze.
"Very well, then. Let's do it again!"
And so, we did it once more.
************************
It initially started as something I would do once in a few days—as a means of releasing my sexual tension.
However, it soon became a daily routine.
Every day, I would go into Karlia's room... and we would have sex.
Day after day, I became one of her customers. But, unlike those suckers, I was getting everything free of charge.
Karlia taught me many things.
Magic. Demon Culture. Miasma... Sex!
We tried various positions, and she showed me a new world I never knew existed in the realm of intercourse.
No moment was boring, and I found myself learning new things as the times progressed.
It didn't take long for my memories of Emilia to start eroding.
I hadn't forgotten her entirely, but, it was simply easier to let her go.
Maybe it was cowardice that caused me to so easily abandon the memories I had with her, or perhaps they were simply overwritten by more exciting ones with Karlia.
Either way, it happened.
Slowly, my feelings began aligning with Karlia... until I was certain it became love. I found it a bit difficult to believe, but before I knew it, I had fallen in love with the Succubus.
A Human and a Demon—who would have thought?
I never told her this, of course. Knowing someone of her caliber, she must have noticed it.
Thankfully, she never mentioned anything about intimate feelings or love.
And so, time elapsed, and two years went by since I first met the Succubus, Karlia.
I got used to my life there.
And, to be honest... I had completely given up on returning home.
My life of Magic research and blissful companionship was the pinnacle of fulfillment.
Each moment, as Karlia got new abilities from new customers, she would show me.
We would study it together, and explore the possibilities.
There were some days when business was slow, but I didn't mind.
That only meant I would have Karlia all to myself.
Many would feel uncomfortable with the idea of having to share the one they loved with others, but I actually didn't mind.
I would be a hypocrite if I did.
It was business. Besides, her interactions with other Demons brought me information concerning the ongoing War, as well as more Intel on Magic.
The latter was more important, as I had given up on ever returning.
According to what I heard... the battle was still at a stalemate.
Usually, Demons gained sustenance by feeding on the corrupted souls of other Races.
Their habitat had grown desolate with the absence of sources of food, so they turned their gazes on the other Races.
That was what caused the war.
Unlike them, Karlia could simply gain sustenance by having intercourse with the Demons who patronized her, so she never lacked her meals.
Since it was necessary, I couldn't exactly complain about her relations with other people.
