My junior high school sister, who has been living in a dirty room for seven years, knows that she is sleeping her first experience, and after that I have spent the night urinating (a contraceptive tool) and processing sexual desires. Kashiwaba-toge Pass

I've been home for the first time in seven years and have a sister who is five years old. My sister is surrounded by junior high school, and I know that she doesn't go to Confucian school, but lives in a nice life, and does not make boyfriends, and is immersed in games and anime. I wondered if her desire to affirm her existence somewhere led to the nightmare, so what should be done as an older brother?
