Finally, delighted that I had deflowered Chaerin, I had sex with her for quite a while.
Chaerin climaxed so many times that it was difficult to keep count.
Her body was already trembling faintly, as though it had reached its limit, and her voice was completely hoarse.
But I showed her no mercy. Rather, as if testing her limits, I thrust deeper and harder.
In the end, when Chaerin climaxed again, I ejaculated inside her for the second time.
Once our violent movements ended, the room was filled with nothing but our ragged breathing.
It felt like we were gradually coming to the end of our sex. I pulled my cock out, wiped the sweat from her forehead, and said.
“Good job, Chaerin. Your pussy really knows how to squeeze.”
“Hng… ah, really…?”
She smiled weakly at my praise. She was completely exhausted now and would have trouble having any more sex.
An orgasm normally demands an enormous expenditure of stamina from a woman. Unless she was someone like Yeji, who exercised every day, she couldn't go on any longer.
Now that the most important sex was over, I thought we could have a serious conversation.
The air touching our still-aroused bodies gradually began to feel cold.
So I picked up the T-shirt lying on the floor and put it on.
But….
“Sihyeok….”
Chaerin called out to me. She was straining to somehow raise her upper body.
“I can still do more. I can have sex better than them….”
Chaerin spoke pleadingly as she came over and rubbed her face against my thigh.
It was her coquettish way of saying she wanted to taste my cock more.
Watching her, I felt slightly puzzled. Chaerin was clinging to sex itself far too desperately right now, even though she was on the verge of collapsing from exhaustion.
Of course, I understood wanting to have more sex after losing one's virginity, but this was an excessively intense obsession.
And the words Chaerin had just said, ‘I can do it better than them.’ felt strange.
“You can do it better than them? Who are they?”
At my question, Chaerin froze. She hesitated for a moment, then answered in a small voice.
“…Than Nari or Yuna. And even Subin… I want to be better than them.”
“What do you mean?”
Still not understanding, I asked again, and Chaerin continued explaining hesitantly.
It turned out that Chaerin had been confident in her ability to satisfy me sexually, but had grown anxious after seeing the other women's skills at the academy.
Nari's overwhelming blowjob skills in particular had dealt a major blow to Chaerin's pride.
I chuckled because I found that lewd competitiveness cute.
She had even heard the sounds of Subin and me having sex just moments ago, so it was understandable that she would feel anxious.
Thinking that, I let my guard down for just a moment, and Chaerin climbed on top of me.
Since she was still wearing only her top, my cock was fully exposed, and Chaerin aligned her pussy with it and slowly lowered her hips.
The second round began with cowgirl-position sex.
-Thrust!
“Hngh…!”
As my cock entered her, Chaerin was intensely aroused, yet desperately tried not to come off it.
Instead, she leaned her upper body toward me and began rocking herself slightly back and forth.
“Oh… this feels good.”
It felt as though the tightly squeezing entrance of her pussy was caressing my cock from inside.
Besides, the sight of Chaerin's large breasts pressing against and flattening over my T-shirt was incredibly arousing.
Since she hadn't yet learned about sexual positions at the academy, her movements weren't skilled.
But that made it even better: the inexperienced movements of a waist filled with pure desire.
That purity made my cock hard again.
As our mucous membranes rubbed together in perfect alignment, a pleasurable sigh escaped me.
“Haa… ah…! Sihyeok, do you like it…?”
“I like it. Keep moving.”
“Yeah, ah, hng, mmm…!”
At my encouragement, Chaerin's movements gradually grew bolder.
Her hips, which had only been moving back and forth, now began drawing circles, kneading my cock from every angle.
Her breasts swayed greatly in time with her movements. The way she shook her hips and squeezed my cock made her look like a ravenous female craving pleasure and semen itself.
Then, true to her quick-climaxing pussy, Chaerin moaned intensely and climaxed first, collapsing on top of me.
-Pshhhhhhht!
“U, u, hwaaang…!”
Her spectacular climax made my cock slip out, and a fountain poured copiously downward from her pussy.
My cock and the mattress were completely drenched in Chaerin's climax fluid.
Because of her consecutive orgasms, Chaerin's eyes nearly rolled back until only the whites showed, but she barely held on.
“Haa, haa, I'm sorry I came again….”
Before I could say anything, Chaerin grabbed my cock again and put it back inside her pussy.
-Squelch!
“Aaaang, ngh…!”
But now that she had truly reached her limit, her body only twitched, and she could barely move her hips.

“Don't overdo it.”
I said gently, but she shook her head.
“No, I'm okay… I can do more, more…. Hngh, huuuh…!”
Watching her move solely to make me feel good was pitiful, yet incredibly arousing at the same time.
So, half out of pity and half because I was aroused, I grabbed Chaerin's buttocks and thrust my hips upward from below.
-Thud!
“Hngiiit…!”
Chaerin screamed at the sudden stimulation. My upward thrusts did not stop.
-Thud! Thud! Thud!
“Hngh! Ah! Ah! This, Sihyeok, ah! Huaa!”
Chaerin covered her mouth, then shook her head back and forth at the mind-melting pleasure. But she never actually told me to stop, struggling somehow to endure. Her willpower was incredible.
Even as I thrust upward from below, knocking against her weak point, her cervix, with my glans, she merely gripped my arm tightly.
“Hieek, hieek, ngh…!”
Chaerin was gradually nearing unconsciousness, making sounds less like a cute woman and more like a female genuinely in the throes of orgasm.
Once again, Chaerin tightly embraced me, kissed me, and reached an incredible climax.
“Wait, j-just.. w-wait.. fo-or.. me.. oooohhh♡ I'm cumming♡”
Along with Chaerin's final climax, I ejaculated into her slick, thoroughly ripe pussy.
* * *
After the sex ended, Chaerin lay with her head on my arm, having barely managed not to pass out.
The room where our incestuous sex had ended was filled with languid heat and the erotic scent created by the two of us.
Listening to Chaerin's breathing with her head on my arm, I sank into a strangely peaceful atmosphere.
The afterglow of our intense pleasure made me feel nothing but happiness, like a drug.
The note and everything else—I didn't want to think about any of it at this moment.
I simply wanted to hold on a little longer to this warmth, this sensation of another person's body heat beside me.
It was a different kind of security from what I felt when I was with Subin.
If being with Subin had felt like thrilling first-time sex with a first girlfriend, then my time with Chaerin had the comfort of finally making it home and lying down on a bed.
Maybe it was because Chaerin was my only family.
‘Family….’
The moment that word began circling through my mind, I suddenly thought of my previous life.
When I was young in my previous life, I often spent entire days just staring at the ceiling like this.
I kept staring and staring and staring at the ceiling illuminated by the blue moonlight coming through the window. I had been alone then, but…
That was when Chaerin burrowed a little deeper into my chest and whispered to me, who had become sentimental while lost in thought.
“…I love you, Sihyeok.”
I briefly held my breath at that confession of love.
Love.
Receiving a confession of love from Chaerin in such a quiet atmosphere, rather than in the middle of sex, made me feel strange.
Thump. Thump. Thump. My heart began beating rapidly.
The heart that had merely fluttered at Subin's confession now throbbed painfully, as though something had struck it.
My body reacted with surprising violence.
I slowly turned my head and looked down at my twin younger sister in my arms. The eyelashes facing me trembled faintly.
“…Could you say that one more time?”
There wasn't a trace of playfulness in my voice; it was utterly serious.
Chaerin's face paled slightly as she met my deep, serious gaze.
But I could see in her eyes that she gradually steeled herself.
At first, she had been afraid of the fact that she had confessed, but as time passed, she seemed to organize her thoughts, gather her courage, and open her mouth.
In a trembling voice, Chaerin brought out the feelings that had festered inside her for more than a decade.
“I mean it. Since long before you could remember… I’ve always loved you. As the only family I had left, and… as a woman.”
Chaerin's confession was etched into my mind. At the same time, it called up memories that had been sleeping deep within me.
So, without realizing it, I told Chaerin the feelings I had hidden from her.
“…The truth is, no one has ever loved me before.”
That was the one sentence that summed up my previous life.
My memories had always been cold: an orphanage where I had been abandoned without knowing my parents' faces or warmth.
The empty playground I looked down on from an old bunk bed.
Sometimes, on weekends, when neatly dressed couples took other children's hands and left, I always watched from the window until their backs disappeared.
No one ever called my name, and no one ever held my hand.
My ugly appearance and introverted personality, so devoid of presence that I was like a shadow.
Girls never paid me any attention, and boys never played with me.
I was always alone, without even a proper friend, let alone a female friend.
My only escape was studying. So I buried myself in my studies, working myself to the bone at my desk.
My dream wasn't grand. Just a stable job, a respectable business card that no one would look down on me for having, and a happy family.
And at last, I did it.
The day I checked the text message announcing my acceptance, I dreamed of the future for the first time, my heart swelling as I stood before a crosswalk.
I thought that now I, too, could live an ordinary life. That I could love someone and be loved in return like everyone else. That at least I would care for my own child with love.
And I was hit by a car while crossing at a crosswalk.
And then Chaerin told me she loved me.
“…Tell me again. Again.”
This time, unlike Chaerin, I was the one who managed to say it in a trembling voice. Chaerin looked at me with a dazed expression.
“What…?”
“That you love me. Say it again.”
Perhaps she had read the desperation in my heart, because Chaerin no longer hesitated.
She gently cupped my cheek, met my eyes, and whispered with all her sincerity.
“I love you. I really love you.”
“Ah….”
I knew nothing about love. I had never received it, so I didn't know.
How to love, what was good about it, or what it did to people.
After coming to this world, ironically, I had only had sex and never loved anyone.
Only now did I feel the magnitude of the love someone else was giving me.
The love Chaerin and Subin had held onto for so long filled my parched heart.
Now I could feel it. I understood what Chaerin and Subin had felt when they confessed to me.
Happiness poured out as though a faucet that had been clogged until now had finally been opened.
So I began to laugh. At first it was a small chuckle, but soon it burst out because I couldn't hold it back.
Yes, now I understand.
All of this was a reward.
If there was a god, then this heaven was a perfect and overwhelming reward for my brutally unfair previous life.
What did it matter if this was fake, or if it was a dream?
The person telling me she loved me, Chaerin's warm body, and all this pleasure were so vividly real.
The note, the conspiracy—none of it mattered anymore.
I stopped laughing and pulled Chaerin into a deep, tight embrace.
A dream I had vaguely cherished long ago, envying the happy family I could see through the orphanage window.
The dream I had given up on as a child, the dream I thought had ended with the accident, now began burning inside me as a vivid future.
So I confessed to Chaerin.
“Let’s get married.”
“Yeah… Huh?!”
“I’m going to build a large family.”
A family filled with love and warmth, with not a single child as lonely as I had been.
I would build a huge family filled with women who loved me and children who resembled them, a family everyone would envy.
I had completely shaken off the ghosts of the past.
I was no longer shaken by my previous life or the note.
My heart burned with a fierce ambition toward a new goal.
‘The first objective in pursuing my goal of building a large family is….’
Selecting women. I needed to choose women suitable to take as my wives.
