Chapter 5: Epilogue: My Beloved Sister Part 1 (Ending 1)
[Since that day, you began to isolate yourself in your dorm, wholly devoting your focus to your writing. You abandoned nearly all social interactions, didn't participate in study groups, nor felt any urge to hang out with others. You became absorbed in immersing yourself within your own world, with Shiina as your only companion; other people held no significance to you.]
[Attending classes, studying, and fulfilling other academic responsibilities were nothing more than obligatory tasks—duties you performed mechanically to remain minimally adapted to society. Despite being a loner and avoiding others, people didn't see you as a NEET; instead, they perceived you as a homebody. Naturally, being attractive played a significant role—if you had been ugly, no amount of excuses would have prevented people from labeling you as a NEET and a loser.]
[As long as Arisu didn't follow her canon path and didn't end up infatuated with Ayanokouji, Class A's position remained essentially stable. It wasn't due to any plot armor for the MC but because of Arisu herself was stronger than plot armor that Ayanokouji have combined and becomes his plot armor instead. Her presence alone created the possibility of Class A being challenged by Class D. Had events unfolded exactly as they did in the original storyline, there would have been a much higher chance of their downfall—such is the impact of Arisu whim, after all.]
[Fortunately, that never came to pass. Arisu did not fall for the protagonist Ayanokouji, nor did she seem to have the time or inclination to do so. As for her feelings toward you, they remained a mystery. Perhaps she has already forgotten about you; even when you don't greet her, she stays indifferent and distant, immersing herself entirely in building her own faction, power, and connections within the school.]
[If all her actions were merely part of a performance, you would find it difficult, almost impossible, to believe. In your earlier years, you gained experience in the performing arts, participating in idol activities and doing part-time acting work as a child. Although you left that world behind, it gave you an understanding of how demanding acting is, how much skill is required to fully embody a character's role. Becoming an actor requires immersing oneself deeply into a character's persona, understanding everything from personality traits to likes and dislikes, a process involving rigorous research and training—training Arisu never had.]
[Maybe your past words dissuaded her entirely, and you didn't pursue the matter further. It was her choice to accept or reject you; you moved on, finding others to care for, and began a new chapter in your life with Shiina.]
[You love her for who she is and would be willing to give her the world.]
[Even writing stories feels endlessly inspiring when you see her smile and witness the lengths she goes to for the sake of the tales you create.]
[Maybe, things aren't so bad after all.]
[Even if you never complete Arisu's yandere storyline, well, life continues, doesn't it?]
[Your phone rang, piercing the silence of the night. You wondered who would be calling at such an hour. To your surprise, you didn't even have Shiina's number, and you realized you had forgotten to ask her for it. The only person who actually knew your number was your sister.]
[Choose:]
[1. Answer the call. You were curious as to why Arisu would suddenly care to reach out, especially at this time of night.]
[2. Don't answer. Your story with her was over. There was no need to respond to her now. She was the one who had started ignoring you, and now it seemed suspicious for her to be calling you in the middle of the night.]
I couldn't help but think—
Why would my sister call me now?
Is this a trap?
Or does she actually need my help?
For safety's sake, no matter how distant we'd grown in our relationship, if she needed help, I would certainly answer her call and do what I could. I picked up the call.
"Brother... Help..." Her voice was soft and trembling before her phone seemed to cut out abruptly. I heard a clattering sound, like the phone slipping from her grasp, followed by silence.
I didn't waste any more time. I rushed to her location, searching for the spare key she had given me when I first enrolled in this school. Back then, before our relationship had grown cold, she had trusted me with it.
Finally, I found it, pocketed it, and raced to her dorm.
Arriving at her door, I unlocked it with her key, only to find her room strangely empty.
I looked around, searching for Arisu, but there was no sign of her.
Just as I was about to leave, the door closed behind me, and I felt a petite figure wrap tightly around me.
"Brother… I missed you," she whispered, her voice filled with an unexpected warmth.
My heart tightened, skipping a beat.
How is this possible?
How could she still have feelings for me after all this time?
I turned toward her, only to be caught off guard as she leaned in and pressed her lips against mine. Her kiss was fervent, filled with a possessiveness I hadn't anticipated.
The intensity blurred my senses, and heat spread through every part of my body as primal instincts took over.
I found myself holding her close, our embrace deepening.
Our lips met passionately, biting at one another until we tasted blood, but no pain or logic could break us from this intense state of need.
She pushed me backward onto the bed, her eyes blazing with an overwhelming lust.
As she pulled down my trousers, I stared at her with equal lust, admiring her bared form as she began stroking me with her hand, softly kissing the tip.
"Brother… Make me yours," she murmured, her voice low and filled with longing.
This cute voice...
This obedient form.
Everything reminded me of how she was still clinging to me. The moment her begging, needy voice formed in my mind, I couldn't hold back any longer.
I pushed her down onto the bed and took her virginity in this very night.
My brain was clouded with pure lust.
No logic, no feelings for Shiina could stop the resurgence of the twisted desire I'd always harbored for my sister.
I kept thrusting into her, holding nothing back.
Even after I'd torn through her hymen, I didn't relent, pounding her wet pussy with everything I had.
Yet, Arisu didn't try to push me away. Despite the roughness, she only held onto me tighter, her arms locking me in place, refusing to let go.
She bit down on my shoulder as if to make sure I couldn't escape.
Even when I felt the need to pull out and cum, she wouldn't let me go, tightening her grip around me.
I had no choice but to shoot my load deep inside her again and again.
We spent hours wrapped up in each other, lost in that intoxicating haze of lust.
When morning finally arrived, I began to grasp the weight of what I'd done.
I'd fucked my own sister, and I'd cheated on Shiina.
How could I have done something so completely depraved?
This is wrong…
But no matter how much I told myself that, a part of me couldn't shake the feeling that everything had felt undeniably right.
Arisu then wrapped her arms around me and whispered in a soft, comforting voice.
"Brother… if you want, you can go back to her and forget everything that happened. I'll give you my blessing."
Is that so?
After everything she did to bring us to this point, would she just let me go?
As my rational mind returned, I realized that I had fallen into her trap from the start. She'd never needed any help—she had orchestrated this moment perfectly, using every step to get exactly what she wanted.
And yet, I felt something else stir inside me.
When she kissed me and trapped me previously, a wave of intense heat spread through my entire body, like a deeper, primal lust awakening and heightening within me, this is not natural.
But instead of questioning it, I said nothing.
I simply leaned in and kissed her, knowing full well that I was committing to everything that had happened.
Now that we were here, there was no point in regret.
I lowered my lips to her neck, ready to give myself to her entirely, accepting the consequences of my own actions.
No matter how carefully she'd set me up, it didn't change the fact that I'd willingly fallen for it, and I wasn't about to run from my responsibilities after taking her virginity.
Unseen by me, a victorious smirk formed on Arisu's face as she stroked my back, her fingers tracing my skin.
We began to fuck again, quickly and passionately, both of us surrendering to the insatiable need for each other.
Her pussy clenched around me, tightening with every intense thrust I drove into her, refusing to let me go.
And so, that's how we spent our morning, tangled together in our moment of raw, unrestrained lust.
