PPS-259 — Sister Marriage (Siscon)! 4 Minato Riku

Just when I was getting used to living alone, my little sister suddenly showed up at my place! My sister has a vivid imagination and started rummaging through my belongings and masturbating. Finally, my sister went beyond mere fantasy and began seducing me, a shut-in anime fan, with various cosplay outfits. With such a cute little sister coming onto me, I couldn't help but lose my self-control! Our relationship had to be kept a secret from our parents. "It's a secret," she said, and I was overcome with a sense of transgressive excitement as I ejaculated inside her with all my might!
