NACR-201 Big-breasted girl Kitagawa Riko, whose entire body was secretly filmed by her geeky brother

Recently, I can't help but feel like someone is watching me. That's why I can't relax even when I'm at home... I talked to my brother about it. But then I noticed something suspicious about his behavior... So I peeked into his room and found him muttering to himself while editing a video he'd secretly filmed me. I felt disgusted and confronted him, but he got mad and raped me...
