G-cup busty NEET stepsister, a NEET (Not in Education, Employment, or Training) girl. Despite her exposed breasts, she's very introverted. Liberate your dormant soul with breast sex and cumshot! Yuuki Koya FOCS-276

It's been a long time since I've been back to my hometown. I heard that my adopted sister, who came into my parents' lives after their remarriage, seems to be a shut-in. I was worried about her, so I went to visit her. It seems Xiao Cai started shutting in because she was teased for having big breasts… Occasionally, I did things like an older brother. When I comforted Xiao Cai, her expression gradually changed… But they're adopted siblings, so it's okay, right? Tempted by her large breasts, I, useless as I am, succumbed to her charm.
