Yandere Simulator Life

[At the end of the day, Arisu emerged victorious once again. It seems impossible to escape her grasp; even when you felt determined to pursue Shiina's path, you found yourself inevitably drawn back to your sister's embrace—her warm yet chillingly possessive grip.]

[It wasn't a forceful hold; she didn't coerce you, nor did she leave you feeling repulsed. Instead, you chose her willingly, not once but twice, sealing your fate by spending the rest of your days entangled in the web of her desires and affections.]

[Shiina lost, and in the end, your sister prevailed.]

[You often wondered if this was fate, a cruel, inescapable destiny, or if there was a hidden path somewhere, a chance to break free from this cycle and venture down a different route.]

[Yet, regardless of those lingering doubts, in this particular world line, the ending diverged from what had come before. This time, your sister was noticeably more magnanimous, softened after learning more about your innermost thoughts during your last heartfelt conversation. Her approach towards you became significantly gentler, showing genuine concern for your emotions.]

[This was a stark contrast to the earlier timeline, where her self-centered attitude led to countless misunderstandings and a toxic high school relationship that only warmed up much later, when the damage had already been done.]

[In the early stages of your renewed relationship, she proposed something that shattered even the wildest bounds of your imagination.]

[Arisu invited Kamuro Masumi to join you both, intending to explore uncharted territory in your intimacy. She was precise in her reasoning; she didn't want to dive in headfirst without testing her comfort level. Arisu needed to know if she would feel jealousy, discomfort, or irritation. It was her way of gauging the boundaries before fully committing to something so unconventional.]

[Arisu was acutely aware of her physical limitations. She knew how her health issues made intense, vigorous sex not only inconvenient but outright risky. You, ever considerate, refrained from pressuring her, choosing instead to cuddle, engage in light foreplay, and show patience. This moved her deeply. It wasn't just that you accepted her limitations without complaint; you actively took care of her, prioritizing her well-being above your own desires.]

[This left her with an overwhelming sense of imbalance. Her pride and ego couldn't accept the dynamic where she only received your kindness without being able to reciprocate. She feared becoming a burden, feeling indebted to you without a way to level the scales.]

[Determined to resolve this disparity, Arisu devised a solution. Aware of her inability to satisfy you sexually due to her health constraints, she knew that your sex drive far exceeded her own. It was clear that this mismatch in libido was creating a significant strain on your intimacy.]

[So, she began to contemplate an unorthodox idea: could she find comfort in allowing another woman to satisfy your needs? It was a risky proposition, one that needed testing before it became a regular part of our lives. Kamuro was the ideal candidate—pragmatic, emotionally detached, and entirely transactional in her approach. There was no risk of her developing feelings; it was simply a physical arrangement.]

[With no emotional entanglement between you and Kamuro, Arisu felt bold enough to proceed with her experiment.]

[You found yourself naked in your dorm room, with Kamuro and Arisu by your side. The atmosphere was charged with anticipation as they began to attend to your need.]

"Are you certain about this, Arisu? We've been in a relationship for two years. I don't believe this was ever the issue before. Why is this coming up all of a sudden?" I asked, unable to hide the confusion in my voice.

It wasn't that I was unwilling to sleep with Kamuro. Despite our lack of emotional depth and connection, she was an undeniably attractive girl. I didn't mind indulging in sex with her—that much was true. But for me, that was all it was ever meant to be: just a sex release, nothing more. Any normal man, when placed in my position, would likely make the same choice as I did.

"Fufufu... But your little friend down here seems to be telling a different story, brother," Arisu teased, her fingers tracing the outline of my erection.

Her gaze was chillingly flirtatious rather than filled with jealousy, making me wonder if this was merely the calm before the storm, or if she was actually testing me.

In the end, it was just my own paranoia. Arisu confidently took hold of my shaft, guiding it towards Kamuro Masumi's face. Kamuro was already on her knees, obedient and ready, as if she had been waiting for this moment all along.

Without hesitation, she took my cock into her mouth, swallowing me down entirely as Arisu instructed her with gentle but firm touches. I couldn't tell if I should be worried or simply take this as an unexpectedly generous gift from my sister.

Rational thought kept trying to claw its way to the surface, insisting that this was wrong, that I should stop.

But my cock, throbbing and fully erect, made the final decision as it always did. I found myself thrusting deeper into Kamuro's throat, driven by pure, animalistic lust, while Arisu held Kamuro's head firmly in place, pressing her against my erection without hesitation.

Even with my body pressed intimately against Kamuro's, my attention remained solely on Arisu. It felt as though I was communicating only with her, sharing some unspoken understanding.

I knew better than to show any signs of affection or concern towards Kamuro; if I did, my sister's calm demeanor would undoubtedly shatter. She was smiling now, but I could sense the possessiveness lurking beneath that expression.

"Sister, I'm about to come," I panted, feeling the pressure building up.

"Inside her, brother," Arisu commanded, her voice smooth and authoritative.

[The sensation overwhelmed you as you released inside Kamuro's eager mouth. The thrill of fucking another woman while your sister watched, teasing and encouraging you, was intoxicating beyond belief. It was a fresh, raw pleasure that sent shivers down your spine.]

[Arisu's doubts had been answered in her own twisted way. It wasn't that she didn't mind you sleeping around—she clearly hated it. But she only tolerated it, even took pleasure from it, when she maintained complete control over the situation. The fact that you ignored Kamuro and focused entirely on her, treating her as the center of your world, pleased Arisu immensely. It solidified a bizarre, unspoken agreement between us, an understanding that this was how things would be from now on.]

[In the mornings, afternoons, or whenever lust overtook you, you were free to indulge in your desires with Kamuro, spending countless hours lost in purely physical passion. But come nightfall, you made love to your sister instead, with a gentleness you'd never shown before. There was no urgency or wild lust when you was with Arisu; instead, you took your time, savoring the moments, cuddling her close, and sharing a deep emotional bond. The raw, flesh-driven sex was reserved for Kamuro, while the true intimacy, the connection of hearts, was for your sister alone.]

[In this world line, neither of us ended up as teachers or headmasters of the school. Instead, we found ourselves with much more freedom in the outside world. You eventually married Kamuro Masumi in name only, while your sister, Arisu, continued living in our home.]

[We reached a mutual agreement that Kamuro would manage any inconveniences caused by Arisu's frail health. In return, Kamuro would enjoy a life of luxury and have the freedom to do whatever she pleased—except one thing: she could not choose another partner. Kamuro had no desire for such things; she preferred her current lifestyle, one where she could indulge in stealing and commit petty theft without fear of any repercussions, as Arisu would always compensate the victims far beyond their wildest expectations.]

[Yes, it could be said that Kamuro suffered from kleptomania, a compulsive urge to steal for the sheer thrill rather than out of financial need. It was a mental illness deeply rooted in her psyche, difficult to cure because it involved complex physiological and psychological factors. The disorder would only worsen over time without proper treatment, but Arisu had no interest in providing that kind of help. Instead, she used Kamuro's condition to bind her to us, keeping her dependent and loyal through this twisted cycle of indulgence and reward.]

[But that's not all there is to our story. To secure a life of luxury and to support both your sister and Kamuro, you started your own company from scratch, building a sprawling business empire. You poured massive investments into the entertainment industry and quickly became a media mogul in Japan. This gave you control over public opinion and ensured that no scandal could harm us.]

[Meanwhile, Arisu inherited her father's vast network of institutions and schools spread across Japan and beyond. In contrast to the previous timeline, where we were confined to the school grounds, hiding our relationship in the shadows, this version of our lives was a resounding success—in terms of our relationship, our wealth, and our pride. This time, we lost nothing.]

[Except for one thing: You were still trapped in her warm, icy grip—your sister's grip, to be precise.]

[And yet, you were content with how things turned out. Your life wasn't perfect, and you carried your share of regrets, just like any other human being. There was the unresolved tension with Shiina, the guilt of exploiting Kamuro's condition, but in the end, your relationship with Arisu was far better than in the previous timeline's ending.]

[However, there was one nagging thought that plagued you...]

[If you could turn back time and leap into another world line, could you make everything perfect? Could you navigate Shiina's route smoothly this time? Could you transform your relationship with Kamuro from something merely transactional into a genuine, heartfelt connection?]

[You don't know the answer. You only know one thing: this is your life—your forbidden, incestuous life with Arisu.]

[In the end, this world belongs to the two of you.]

[Happy Ending 2 (Arisu Sakayanagi & Kamuro Masumi's Route): Her Warm, Icy Grip]

[Evaluation: Damn, man, you're a legend! You managed to get a yandere to willingly join a threesome and share you with another woman. What a Gigachad! What a legend! I knew I chose the right person!]

And so, that's how it all turned out. I ignored the evaluation displayed before me, focusing instead on the two women lying naked beside me in bed: Arisu Sakayanagi and Kamuro Masumi, their bodies entangled as they held onto me.

Now, I only wanted to spend more time with them, savoring every moment until death eventually tore us apart. The game could wait—I had my own paradise right here.

...

A/N: Here we go—the ending, my friends.

Yeah, I know I'm kinda late with this, but hey, better late than never, right?

I'm not sure if I'll be back updating regularly tomorrow, next week, or even next month. Meh, I just wanted to let you know—I'm not dropping this fic, so don't worry about that.

Next up is the Hiyori Shiina route. It's gonna start as her solo route, but I'm also considering making it Hiyori Shiina & Arisu together.

That was always supposed to be the main route, but I haven't fully decided yet. I mean, I don't even have a stockpile of chapters for this right now.

I'll update when I've stocked enough chapters for both the Shiina route and the Shiina & Arisu route. And yeah, to be precise, it's gonna be a threesome route—wink wink.

Once we're done with their route, we'll move on to the other heroines.

Arisu, though, she's special. She's the kind of character who can be anything depending on the route—a powerful ally, a main heroine, or even the antagonist.

That's exactly why she's one of the main girls.

Anyway, that's all for now.

Goodbye, and I hope you enjoyed this ending.

See you in the next route!
