Today I'm writing on the topic of "soapland, good money, Warabi."
I'll explain it by mixing in my own firsthand experience from 20-plus years in fuzoku with information I've dug up through research.
The basics
Let me lay out the fundamentals you should know about this area.
When you've watched this industry for a long time, you find that even the same topic gets graded completely differently from the "customer's side" versus the "girl's side."
What I can say from firsthand experience
I'll talk based on what I've gone through myself.
I believe firsthand experience matters more than theory. This industry especially is a world where "rounds logged" speaks louder than "knowledge."
Wrap-up and my conclusion
Where I end up going again and again is First Class Ruby. The reason it keeps showing up on this site is simply that it's a shop I repeat at. Take it as a reference.
