COGM-052 — I Can Forgive My Sister Being A Naturist, But I'm Very Bothered By The Fact That She Masturbates Anywhere And Everywhere.

※A new label has arrived at Koguma! It's called Organic INRAN! The theme is "What if I had a pervert like this in my daily life!" My sister is a naturist. I can still forgive that. I hear about it quite often. But she's also addicted to masturbation. It's not a lie. She probably masturbates to the point where she'll die if she doesn't touch her pussy every day. But I'm a college student. My sister works and earns us a living, so I can't say anything. Well, I know that I should say something as her younger brother, but I get excited when I see that, so I can't bring myself to say it. If I warned her and she said, "Okay. I get it," that would be sad in itself. So I was in a state of turmoil, and then my sister asked me to help her masturbate. What should I do?! I'm almost a virgin!
