COGM-052 I can tolerate my sister being a nudist, but it's really troublesome that she masturbates anywhere and anytime.

*A new label has appeared in Koguma! The name is organic INRAN! The theme is "What should I do if there is such a perverted child in everyday life!" My older sister is a tribe. It's still acceptable. It's a story I hear a lot. But she is also addicted to masturbation. I'm not lying. Really, she probably masturbates to the level that if she doesn't touch her pussy on a daily basis, she won't die. But I'm a college student. I can't say anything before my sister works and earns her living expenses. No, I know that I should say it as my younger brother, but I can't say it because I get excited when I see it. If you pay attention and say, "Oh, I understand.", that's sad. When I was annoyed by such a thing, my girlfriend's older sister told me not to help me with masturbation. What am I going to do! ? I'm almost a virgin!
