This book is a fanfic written by the author based on his high school obscenity. Don't let anyone offend you. The characters in the book are all replaced by letters. Only the protagonist has a name. You can read it as a quick travel story and have fun.
Why is it only allowed to have sexual intercourse and not to have sexual intercourse with boys? This kind of thing is unfair. That's why I thought of uploading some erotic essays I wrote in high school.
Intention: lust is the most important thing
