My older sister is a late-20s NEET loser. When I was little, my mother left home and ran off with another man, abandoning me. Every night, my father cried. It was heartbreaking. At school, I always acted cheerful—I didn’t want anyone to know about my family. A few years later, my father remarried and we gained a new family: a kind stepmother and a loving sister. We lived happily together. Truly happy. Years passed, and I left my hometown for Tokyo to attend university. Living alone for the first time was scary, but my parents were proud—seeing their joy made me happy too. Then, years later, my father passed away. Today marks the anniversary of his death, and I’ve returned home after a long time. My hometown hasn’t changed. My mother is healthy. My sister is the same as ever. Just seeing that made me happy. But I couldn’t express it in words. Deep inside me, there was a feeling I’d never resolved. I moved to Tokyo to bury that emotion. Looking up at the sky, I saw the same beautiful expanse as before. And suddenly, I wanted to scream, “I’m way too worried about my sister!!!!!!!” She’s a late-20s loser: messy room, wearing ugly sweatpants, dorky glasses, addicted to gaming, unemployed, no bra, wearing old man socks. A full-house loser. She’s endlessly playing a Game Boy Advance. My sister hasn’t changed—still glued to her Game Boy Advance, playing Metroid Fusion. Worried about her lifestyle, I secretly peeked into her room. There she was, shamelessly masturbating. Using a worn-out piston vibrator, squatting awkwardly, poking at her genitals. Prodding away. Poke, poke, poke, poke. Like a woodpecker. Woodpecker, poke poke, woodpecker cunt. Years without seeing a cock. Without touching one. Without feeling anything. So she had no choice but to relieve herself. It was pitiful. I wanted to cry. To sob out loud. To sprint across an endless plain. To scream until I vanished into a thousand winds. But honestly, I was rock hard. Rock hard for my sister. So I attacked. I ruthlessly pounded her with the vibrator. I brutally deep-throated her. I slammed my fully erect cock into my sister’s pussy, ready and waiting. “Sister, is a cock after years away feeling good?” “Sister, is it warm?” Again and again, intense creampie after creampie. My sister, overwhelmed by years of pent-up lust, orgasmed violently. Then I came inside her. But her sexual frenzy didn’t stop. “We’re not even blood-related…” Turned into a sex beast, she forced me into a second creampie, twisting my nipples with her saliva… Sister… Ameiri-nee… If a child is born, please forgive me. If it’s a boy, I’ll name him 【Satoshi】. After Father’s name…!!!!!!
