Today I'm writing on the theme of "Warabi fuzoku bloomers."
I'll explain it by mixing my own firsthand experience — 20-plus years in fuzoku (Japan's licensed adult-entertainment business) — with what I've dug up through research.
The basics

What I can say from experience
I'll talk based on what I've actually lived through.
I believe firsthand experience beats theory. Especially in this business, it's "reps on the mat" that matter more than "knowledge."
Wrap-up and my verdict
The place I keep coming back to is First Class Ruby. The reason it keeps showing up on this site is simple: it's a shop I actually repeat. Use it as a reference.
