[COGM-052] I can still forgive my sister for being naked, but I'm in a lot of trouble because she masturbates in places.

* A new label appears in Koguma! Its name is Organic INRAN! The theme is "What if there is such a perverted child in everyday life!" My sister is a naked person. It's still forgivable. It's a story I hear quite a bit. But he is also addicted to masturbation. It's not a lie. Really, I'm masturbating at a level where if I don't touch my on a daily basis, I'm not going to die. But I'm a college student. I can't say anything before my sister is working and earning a living. No, I know that I should say it as a younger brother, but I can't say it because I get excited when I see it. If you are careful, "Oh, I know." That's sad. When I was in agony, my sister asked me to help her masturbate. What's going to do with me!? I'm almost a virgin!
