[My Stepmom Sister Is a 30-Something NEET Virgin (Sob)] When I was just six years old, my father remarried. I was genuinely happy to have a new family—having a mother and sister, all getting along so well, truly made me happy. A few years later, I moved to Tokyo for a new job. My father was proud, my mother was proud—it was the happiest moment of my life. But a few years after that, my father suddenly passed away. Today marks his death anniversary, and I've returned home after a long time. The hometown hasn't changed. My mother is healthy, and my sister remains the same. Just seeing that filled my heart. Yet, deep down, something lingered. A feeling I've suppressed for years. Maybe that was why I left home in the first place. At that moment, gazing at the sky, emotions welled up inside me. I couldn't stop worrying about my sister. She's a 30-something NEET virgin who's been using the same Game Boy Advance for ten years straight. Her game? "Let's Gather!! Melodin World." Her life hasn't changed at all. Watching her secretly as she walked toward her room, my heart trembled. She was pleasuring herself with a worn-out piston vibrator, tormenting her vagina that hadn't felt a man's touch in a decade. Poking awkwardly, masturbating shamelessly. Seeing her like that, my chest ached. She was forcing herself into a sweet, artificial life just to find release. And at that moment, I pounced on her. I ruthlessly pounded her with the vibrator, made her climax like a beast. Then, fully erect and burning with arousal, I shoved my cock into my sister's pussy. "Sister, is this cock after ten years feeling good?" "Sister, is this cock after ten years warm enough?" Again and again, brutal deep thrusts. My sister, overwhelmed by a cock after ten years, burned with intense lust, climaxing violently. Then, creampie. But her excitement didn't stop. In the end, I came inside her pussy three times. Sister... Iori-nee... if you get pregnant, please forgive me.
